The present disclosure relates to a cooking apparatus, and in particular, a cooking apparatus provided with a door for opening and closing a cooking compartment.
Cooking apparatuses are installed in the kitchen and used to cook food items as the user wants. Cooking apparatuses can fall into different categories, based on a heat source or a type, and the sort of fuel.
Additionally, cooking apparatuses can be categorized into an open cooking apparatus in which a food item is placed in an open space, and a sealed cooking apparatus in which a food item is placed in a closed space, based on a space in which a food item is placed. The sealed cooking apparatus comprises an oven, a microwave oven and the like, and the open cooking apparatus comprises a cooktop, a hob, a griddle and the like.
In the sealed cooking apparatus, a space in which a food item is placed is shielded, and the shielded space is heated to cook the food item.
In the sealed cooking apparatus, provided is a cooking compartment in which a food item is placed and which is shielded when a food item is cooked, is provided in a main body. The cooking compartment is a space in which a food item is substantially cooked.
A door is swivably provided at the sealed cooking apparatus and selectively opens and closes the cooking compartment. The door may be swivably installed at a main body by a door hinge provided between the main body having the cooking compartment therein and the door. The door swivels around a portion where the door is coupled to the main body through the door hinge, to open and close the cooking compartment selectively.
A heat source may be provided in the inner space of the cooking compartment opened and closed by the door. The heat source is provided to heat the cooking compartment. The heat source may comprise a gas burner or an electric heater and the like.
An electronic component compartment may be disposed over the cooking compartment. Electronic components needed to operate the sealed cooking apparatus may be provided in the electronic component compartment. The electronic component compartment is formed apart from the cooking compartment.
A cooling fan for cooling the electronic component compartment may be provided in the electronic component compartment. The cooling fan may be provided in the form of a centrifugal fan such as sirocco fan, and disposed eccentrically toward the rear of the electronic component compartment.
The cooling fan may suction external air and allow the external air to flow into the electronic component compartment, and discharge hot air in the electronic component compartment forcibly to the outside to cool the electronic component compartment.
The main body may comprise a cavity and a front panel. The cavity may form the skeleton of the main body, and the cooking compartment may be formed in the cavity. The front panel may be disposed at the front of the cavity and form the front surface of the main body.
The electronic component compartment may be disposed over the cavity. The front surface of the electronic component compartment may be shielded by the front panel. For example, at least a portion of the front panel may protrude to the upper portion of the cavity, and the upper area of the front panel disposed over the cavity may shield the front surface of the electronic component compartment.
The front panel may have an exhaust opening. The exhaust opening may be formed in such a way that the exhaust opening penetrates the front panel in a front-rear direction. The exhaust opening may form a passage for discharging air in the electronic component compartment to the outside, on the front panel.
The exhaust opening may be disposed on the front surface of the electronic component compartment, i.e., in the upper area of the front panel. Additionally, a discharge flow path may be formed at the front side of the exhaust opening. A control panel and the door may be disposed at the front side of the exhaust opening, and a gap of predetermined height may be formed between the control panel and the door that are disposed in an up-down direction. The discharge flow path may be formed in the gap between the control panel and the door.
The exhaust opening may connect to the discharge flow path while being exposed toward the discharge flow path. Additionally, at least a portion of the exhaust opening may be exposed to the front of the cooking apparatus through the discharge flow path. That is, at least a portion of the exhaust opening may be exposed forward through the gap between the control panel and the door.
Air drawn into the electronic component compartment by the cooling fan in the electronic component compartment may be discharged out of the electronic component compartment through the exhaust opening. Additionally, the air discharged through the exhaust opening may be discharged to the front of the cooking apparatus through the discharge flow path between the control panel and the door.
Further, heat generated in the cooking compartment during cooking may be transferred to the outside of the door through the door. To block the conductive heat, the door may be provided with a plurality of glasses.
For example, a front glass disposed on the outer surface of the door and a rear glass disposed on the inner surface of the door may be provided at the door, and a plurality of intermediate glasses may be installed between the front glass and the rear glass. Each of the intermediate glasses may be provided in such a way that the intermediate glass is coated for heat shielding.
Heat in the cooking compartment may be transferred to the inner surface of the door and then to the front glass through the intermediate glass in the door, such that conductive heat is blocked by the radiation energy reflection coating of the inner glass.
Further, a discharge hole may be provided at the upper end of the door. The discharge hole may be formed in such a way that the discharge hole penetrates the upper end of the door in the up-down direction. Through the discharge hole, hot air in the door may be discharged to the discharge flow path. At the same time, cold air may be suctioned into the door from which the hot air escapes, through the lower portion of the door.
That is, hot air in the door may be discharged to the upper portion of the door, and cold air is drawn into the door through the lower portion of the door, and based on the flow of the air, the door may cool.
As described above, the discharge hole may be disposed at the upper end of the door. The discharge hole disposed at the upper end of the door may connect to the discharge flow path. That is, hot air discharged through the exhaust opening and hot air discharged through the discharge hole may be combined in the discharge flow path.
Hot air discharged out of the electronic component compartment through the exhaust opening may pass through the upper area of the discharge hole and then be discharged out of the cooking apparatus, while passing through the discharge flow path. During the process, hot air flowing in the discharge flow path may flow reversely into the door through the discharge hole.
That is, air discharged out of the electronic component compartment may flow reversely into the door through the discharge hole without escaping out of the cooking apparatus. In the case where such a reverse flow occurs, cold air may not be properly drawn into the door, and accordingly, the door may not cool smoothly.
An oven is disclosed in prior art document 1 (KR Patent Publication No. 10-2015-0030016)
The oven 1 in prior art document 1, as illustrated in
The cooking compartment 20 is a cooking space formed by an upper plate 21, a bottom plate 22, both lateral plates 23 and a rear plate 24. A variety of components constituting the oven 1 may be built into a space (hereinafter, “electronic component compartment”) between the outer portion of the cooking compartment 20 and the casing 10. A control panel 12 for controlling the operation of the oven 1 may be installed in the upper end portion of the casing 10.
A cooling fan 50 may be installed outside the upper plate 21. The cooling fan 50 may suction external air into the electronic component compartment through at least one of openings installed on the rear plate 11 of the casing 10 and the like, and then be discharged the air drawn into the electronic component compartment to the outside again.
A cooling flow path 55 may be provided in the electronic component compartment. The cooling flow path 55 forms a passage allowing air suctioned by the cooling fan 50 to flow toward the front surface of the oven 1.
A cooling outlet 57 may be provided at the front side of the cooling flow path 55. Air having passed through the cooling flow path 55 may be discharged to the upper portion of the door 30 through the cooling outlet 57. The cooling outlet 57 may be disposed further rearward than the door 30.
A cooling guide 80 may be installed in the end portion of the front side of the cooling outlet 57. The cooling guide 80 may be shaped into a bracket that bends to narrow the width of the cooling outlet 57.
In the cooling outlet 57 the width of which is narrowed by the cooling guide 80, the flow velocity of air passing through the cooling outlet 57 may increase. Accordingly, the air passing through the cooling outlet 57 is discharged out of the oven 1 at high speed, and while the pressure of the cooling outlet 57 decreases, air around the cooling outlet 57 may be collected around the cooling outlet 57.
The force of collecting air around the cooling outlet 57 to the upper portion of the door 30 may lead to discharge of air in the door 30 to the upper portion of the door 30.
In prior art document 1, the discharge of air in the door 30, guided as described above, helps to facilitate the inflow of cold air into the door 30 and suppress a reverse flow of air discharged through the cooling outlet 57 into the door 30.
However, problems of prior art document 1 are described as follows.
According to prior art document 1, air having passed through the cooling outlet 57 and air having been discharged from the door 30 are discharged to the front of the cooling outlet 57 and a space on the door 30.
That is, while air discharged through the cooling outlet 57 and air discharged out of the door 30 are combined in one space, eddy current may be generated in the space. As the eddy current is generated, the air having passed through the cooling outlet 57 and the air having been discharged from the door 30 may not be properly discharged out of the oven 1, and air in the space may flow reversely into the door 30.
At this time, the inner portion of the electronic component compartment may not cool properly, and the inner portion of the door 30 may not cool properly.
Additionally, in prior art document 1, the cooling guide 80 may be elongated in the lengthwise direction thereof, along the lower portion of the cooling outlet 57, and fixed to the lower portion of the cooling outlet 57.
If the cooling outlet 57 is formed in such a way that the cooling outlet 57 is divided into a plurality of cooling outlets along the widthwise direction of the oven 1, the cooling guide 80 fixed to the lower portion of the cooling outlet 57 needs to be provided in a plurality of numbers.
At this time, the man-hour of assembly and the number of components required to install the cooling guide 80 increase.
Additionally, in the case where the cooling outlet 57 is provided in succession along the widthwise direction of the oven 1, that is, in the case where one long cooling outlet 57 is only formed at the oven 1, the strength of the front surface of the casing 1 decreases.
Additionally, in the case where meat or a food item containing meat is heated and cooked with a sealed cooking apparatus described above, an oily ingredient such as fat or oil and the like from the food item, floating in the cooking compartment, is attached to the wall surface of the cooking compartment and contaminates the inner wall of the cooking compartment.
The oily ingredient attached (adhering) to the wall surface of the cooking compartment may be polymerized (reacted) and firmly fixed, and may be hardly cleaned (removed).
Among cooking apparatuses that have been launched in recent years, cooking apparatuses have a self-cleaning function of automatically removing contaminants such as an oily ingredient and the like described above.
The self-cleaning function involves automatically removing a contaminant such as an oily ingredient and the like attached (adhering) to the wall surface of the cooking compartment.
In a cooking apparatus, the self-cleaning function is performed in such a way that a heat source such as a burner or a heater heats the inner portion of the cooking compartment to keep the inner portion of the cooking compartment at high temperature for a long period, such that a contaminant is burned and removed based on pyrolysis (thermal degradation) in the case where a contaminant such as an oily ingredient and the like is attached to the wall surface of the cooking compartment.
A thermal degradation cleaning function similar to or the same as the self-cleaning function is also disclosed in prior art document 1. The cleaning function is performed in such a way a control unit 38 in prior art document 1 increases temperature in the cooking compartment 20 to thermally degrade a contaminant. The thermal degradation cleaning function may be performed in such a way that an electric heater 42 is used to keep the inner portion of the cooking compartment 20 at high temperature for a long period to burn and remove a contaminant.
During the thermal degradation cleaning, the inner portion of the cooking compartment 20 may be maintained at high temperature. To prevent an accident, the door of the cooking apparatus needs to be closed firmly during the self-cleaning operation.
To the end, the oven 1 may be provided with a door locking mechanism. The door locking mechanism may be installed on the front surface of the oven 1, and may comprise a latch provided in such a way that the latch is holdable at the door 30, and a driving unit for operating the latch.
The driving unit may comprise a motor, and the driving unit and the latch may be connected by a link structure. While the door 30 needs to remain closed, the latch remains held at the door 150. In the case where the door 30 does not need to remain closed, the latch may be unheld from the door 30.
The latch may be installed on the front surface of the oven 1, and protrude to the front of the oven 1 while rotating forward. The latch may protrude while rotating forward and be held at the door 30, and escape from the door 30 while rotating rearward.
A hold groove may be provided at the upper end of the door 30, and the latch may be inserted into the hold groove from the upper portion of the hold groove and held at the door 30, such that the door 30 is locked by the door locking mechanism.
When necessary, the latch may be installed on the front surface of the oven 1 in such a way that the latch is exposed to the front of the oven 1. The latch may be disposed further upward than the door 30 such that the latch comes in and out of the hold groove provided at the upper end of the door 30.
According to prior art document 1, in the case where the latch is installed at the above-described position, the latch is exposed to the front of the oven 1 in the state where the door 30 closes the cooking compartment 20 as well as the state where the door 30 opens the cooking compartment 20.
That is, the latch disposed further upward than the door 30 is exposed to the front of the oven 1 through a gap between the door 30 and a control panel, causing deterioration in the aesthetic quality of the oven 1.
Further, a cooking apparatus is disclosed in prior art document 2 (FR Patent No. 2746903).
The cooking apparatus in prior art document 2, as illustrated in
The component 5 may be installed at the door 2 and divide a second air current F2 flowing along a cooling flow path formed by the duct 3 in the up-down direction. The component 5 may divide the second air flow F2 into an upper air current Fa2 at an upper side and a lower air current F2b at a lower side, at the outlet side of the cooling flow path.
Out of the upper air current Fa2 and the lower air current F2b divided as described above, the lower air current F2b moves at higher speed than the upper air current Fa2. The lower air current F2b may be discharged forward after being combined with the first air current F1 moving upward in the door 2.
Problems of prior art document 2 are described as follows.
According to prior art document 2, the lower air current F2b at the lower side is combined with the first air current F1, such that flow resistance increases in a space between the upper portion of the door 2 and the component 5.
As the flow resistance increases as described above, the amounts of the first air current F1 and the second air current F2, discharged forward, decrease, causing deterioration in the cooling performance of the cooking apparatus.
Further, as the flow resistance increases as described above, noise around the door 2 increases.
According to prior art document 2, the first air current F1 and the lower air current F2b are discharged through the lower side of the component 5, and the air currents are discharged forward at a position very close to the door 2.
During this process, the flow of discharge of hot air increases the temperature of the front surface of the door 2, while contacting a glass panel 2a of the door 2.
Further, according to prior art document 2, a path in which the lower air current F2b flows through the lower portion of the component 5 communicates with an outlet of the upper end of the door 2. Accordingly, a portion of the lower air current F2b may be drawn into the door 2, or a portion of the first air current F may flow reversely into the door 2.
As the above-described phenomenon occurs, the temperature of the door 2 may increase, causing deterioration in product reliability and increasing the possibility that the user is burned.
Further, according to prior art document 2, the component 5 contacts the flow of discharge of hot air for a long period at a time of operation of the cooking apparatus. Since the component 5 is installed at the door 2, the component moves toward the user along the door 2 in the case where the door 2 is opened.
Thus, at a time when the door 2 is opened, the user is highly likely to be burned by the component 5 of high temperature.
The objective of the present disclosure is to provide a cooking apparatus having an improved structure in which flow resistance that is generated while air discharged from an electronic component compartment and air discharged from a door are combined.
Another objective of the present disclosure is to provide a cooking apparatus having an improved structure in which an increase in the temperature of the front surface of the door, caused by a flow of discharge of hot air, is suppressed.

Another objective of the present disclosure is to provide a cooking apparatus having an improved structure in which the cooking apparatus is less affected by high-temperature air discharged from the cooking apparatus, and the aesthetic quality of the cooking apparatus improves.
Yet another objective of the present disclosure is to provide a cooking apparatus having an improved structure in which improvement in the aesthetic quality of the cooking apparatus as well as suppression of the generation of eddy current are ensured.

The air guide comprises a first guide part configured to partition the space between the control panel and the door in an up-down direction, and a second guide part configured to block a space between the first guide part and the door.
Accordingly, in the present disclosure, air currents may be combined in the upper space of the air guide rather than the lower space of the air guide, which is adjacent to a door exhaust opening, and air may be discharged only through the upper space, ensuing a decrease in flow resistance generated in the process of combining the air currents.

In the cooking apparatus of the present disclosure, air may be discharged only based on a flow through the upper space of an air guide in the state where the lower space of the air guide, adjacent to a door exhaust opening, is blocked by the air guide.
In the air guide of the present disclosure, air currents may be combined in the upper space of the air guide rather than the lower space of the air guide, adjacent to the door exhaust opening, and air may be discharged only through the upper space of the air guide.
The air guide guiding the flow of discharge of air may help to reduce flow resistance generated while air currents are combined, such that the generation of eddy current decreases significantly at the fronts of the air guide and the cooking apparatus.
Accordingly, in the present disclosure, the amount of air discharged after the cooking apparatus cools may increase effectively, and noise generated due to flow resistance and eddy current may decrease.
In the present disclosure, the flow of air may be guided to discharge the air through a first space of an anterior space, which is eccentric upward, such that a distance between hot air discharged to the front of the cooking apparatus and a door increases.

In the cooking apparatus comprising the air guide, the possibility that the user contacts the air guide that may have high temperature due to its contact with the flow of discharge of hot air may decrease, such that the user is effectively prevented from being burned by a high-temperature component in the case where the user opens the door.
In the cooking apparatus, flow resistance generated while air is combined may decrease, and air may move in the upper space of the air guide, which is far away from the door, such that a reverse flow of air discharged from an electronic component compartment into the door is suppressed effectively.
In the cooking apparatus, the door exhaust opening may be disposed at a position where the door exhaust opening escapes to a maximum degree from an area where air discharged through an exhaust opening flows, such that a reverse flow of hot air discharged to an anterior space into the door is suppressed effectively.
In the cooking apparatus, a portion of structures exposed trough an anterior gap may be covered by the air guide providing a structure that covers an anterior gap while crossing the anterior gap laterally, such that the aesthetic quality of the front surface of the cooking apparatus improves.
In the cooking apparatus, the user's gaze may be focused on the air guide in the case where the user looks at the anterior gap, such that the user feels like the air guide is only in the anterior gap because of an optical illusion, ensuring improvement in the aesthetic quality of the front surface of the cooking apparatus.
In the cooking apparatus, since a first guide part forming the front surface of the air guide is disposed in a central position of the anterior gap, the upper area of the anterior gap and the lower area of the anterior gap may be symmetrical to each other, such that the exterior of the front surface of the cooking apparatus looks reliably while the aesthetic quality of the cooking apparatus improves.
In the cooking apparatus, the lower area of the anterior gap may be covered further by a second guide part that is disposed at a less noticeable position than the first guide part disposed at the front of the air guide.
In the cooking apparatus, the shape of the front surface of the cooking apparatus may look reliably while the aesthetic quality of the front surface of the cooking apparatus may improve.
In the cooking apparatus, a structure such as a latch having a large complex shape may be covered by an outer cover projection provided to fix the air guide, such that the air guide is fixed reliably while the aesthetic quality of the front surface of the cooking apparatus improves.
In the cooking apparatus, an inner cover projection may be disposed at a position where the inner cover projection covers a separation wall partitioning between an exhaust opening and an exhaust opening from forward such that the inner cover projection does not interfere with the discharge of air through the exhaust opening and is less likely to be thermally deformed, while the aesthetic quality of the front surface of the cooking apparatus improves.
In the cooking apparatus, the air guide may be made of a metal material having excellent heat resistance, such that the air guide disposed on a path in which high-temperature air is discharged is not easily deformed despite high-temperature heat and is not easily damaged despite an impact, while its metallic luster helps to improve the aesthetic quality of the cooking apparatus.
In the cooking apparatus, the air guide may be disposed eccentrically toward the front of the anterior space, in the anterior space, such that the generation of eddy current is suppressed in the anterior space, while the aesthetic quality of the cooking apparatus improves.

In this embodiment, the cover projection 210, 220 may be coupled to at least any one of the first guide part 310 and the second guide part 320.
In another example, the air guide 300 may only comprise the first guide part 310 or the second guide part 320. In this embodiment, the air guide 300 comprises both the first guide part 310 and the second guide part 320, for example.
The second guide part 320 may be a portion disposed at the rear side of the air guide 300, and disposed further rearward than the first guide part 310. The second guide part 320 may connect to the first guide part 310, at the rear side of the first guide part 310. The second guide part 320 provided as described above may block the second space S2.
The second guide part 320 may be provided to block the second space S2, between the first guide part 310 and the door exhaust opening 152. The second guide part 320 may extend from the first guide part 310 rearward in such a way that the second guide part 320 inclines downward.
In an example, the first guide part 310 may be shaped into a planar surface parallel with the lower surface of the control panel 120 or the upper end surface of the door 150. At this time, the first guide part 310 may have a shape comprising a planar surface across the up-down axis.
The second guide part 320 may be provided in such a way that the second guide part 320 connects to the first guide part 310 in the front-rear direction. The second guide part 320 may be formed to extend rearward from the rear end of the first guide part 310.
In an example, the second guide part 320 may be shaped into an inclination surface that extends rearward from the rear end of the first guide part 310. At this time, the second guide part 320 may be shaped into an inclination surface that extends downward toward the rear side of the second guide part 320.
The second guide part 320 formed as described above may block the second space S2, between the first guide part 310 and the door exhaust opening 152, and prevent a forward movement of air through the second space S2. Detailed description in relation to this is provided hereinafter.
In another example, an air guide 300a may comprise a first guide part 310a and a second guide part 320 that connect to each other linearly (see
At this time, the first guide part 310a may be shaped into an inclination surface that extends to the front of the second guide part 320 linearly.
The air guide 300a formed as described above may allow expand an area covered by the air guide 300a, in the up-down direction, in an anterior gap, and allow air to be discharged to the front of the cooking apparatus through the anterior space.
In another example, an air guide 300b may comprise a second guide part 320b that has a curved line shape (see
At this time, the second guide part 320a may have a curved shape the upper surface of which is convex, while the second guide part 320a is formed to incline downward toward the rear thereof.
The air guide 300b formed as described above may smoothly guide a flow of air toward the second guide part 320b forward along the curved surface of the second guide part 320b.
The air guide 300b may decrease resistance that is generated as air discharged through the exhaust opening 122 contacts the second guide part 320b.
The air guide 300b may allow air to be discharged smoothly to the front of the cooking apparatus through the anterior space.
In another example, an air guide 300c may comprise a first guide part 320c and the second guide part 320b that connect in the form of one curved line (see
At this time, while the first guide part 320c extends to the front of the second guide part 320b, the first guide part 320c may be shaped into a curved line smoothly connecting to the second guide part 320b. At this time, like the second guide part 320b, the first guide part 320c may be shaped into a curved line the upper surface of which is convex.
The air guide 300c formed as described above may have an exterior more smooth than the exterior of the air guide 300b illustrated in
Further, the air guide 300, as illustrated in
In this embodiment, the fastening projection 330 may be disposed toward the second guide part 320 that is disposed further rearward than the first guide part 310. The fastening projection 330 may be formed to protrude from the second guide part 320 in the up-down direction.
Each fastening projection 330 may be coupled to the cover projection 210, 220. In an example, the plurality of cover projections 210, 220 and the fastening projection 330 may be disposed in such a way that each cover projection 210, 220 and the fastening projection 330 touch each other in the up-down direction. As each cover projection 210, 220 and the fastening projection 330 touching each other in the up-down direction are coupled, the control panel 120 and the air guide 300 may be coupled to each other.
The air guide 300 may further comprise an extension part 315. The extension part 315 may be disposed at both sides of the first guide part 310 in the lateral direction thereof. The extension part 315 may be formed to protrude from the first guide part 310 laterally.
The extension part 315 is not a portion that is coupled to the cover projection 210, 220. Accordingly, the length of the extension part 315 may be less than the entire length of the air guide 300.
Since the extension part 315 is formed in such a way that the length of the extension part 315 is less than the entire length of the air guide 300, the entire size and the weight of the air guide 300 may not increase unnecessarily.
The extension part 315 may be disposed eccentrically toward the front side of the air guide 300, on the air guide 300. Preferably, the first guide part 310 and the extension part 315 may connect laterally, such that the end portion of the front side of the extension part 315 and the end portion of the front side of the first guide part 310 are disposed on the same line.
In this embodiment, the extension part 315 protrudes from the first guide part 310 to have the same length as the length of the first guide part 310, for example.
Accordingly, despite the fact that the length of the extension part 315 is less than the entire length of the air guide 300, the exterior of the air guide 300 viewed from forward may be formed to connect smoothly.
Further, the extension part 315, as illustrated in
The extension part 315 disposed at the front of the protrusion surface part 123 has a length less than the length of the first guide part 310, as described above, and is disposed eccentrically toward the front of the air guide 300, on the air guide 300, to avoid interference with the protrusion surface part 123.
That is, the extension part 315 formed as described above may produce the effects of maintaining the aesthetic quality of the air guide 300 viewed from forward and preventing an unnecessary increase in the size and weight of the air guide 300, while avoiding interference with the protrusion surface part 123.
Referring to
In an example, a portion of the front panel 120 may be exposed to the front of the cooking apparatus through the anterior gap. Specifically, the plurality of exhaust openings 122 provided at the control panel 200 may be exposed to the front of the cooking apparatus through the anterior gap. Additionally, the separation walls 121 disposed between the exhaust openings 122 may be exposed to the front of the cooking apparatus through the anterior gap.
Further, a portion of a variety of electronic components disposed in the electronic component compartment 250, which is disposed at the rear of the exhaust opening 122, may be exposed to the front of the cooking apparatus through the anterior gap.
Further, at least a portion of the door locking mechanism may also be exposed to the front of the cooking apparatus through the anterior gap. For example, most of the latch 140 may be exposed to the front of the cooking apparatus through the anterior gap. Further, a portion of the driving unit 145 together with the latch 140 may be exposed to the front of the cooking apparatus through the anterior gap.
In the case where the above components are exposed to the front of the cooking apparatus, the components may adversely affect the exterior of the front surface of the cooking apparatus. That is, structures such as an exhaust opening 122 and a separation wall 121 formed at the front panel 120, a structure such as a latch 140 and the like having a complex structure, and electronic components exposed through the exhaust opening 122 may be factors causing deterioration in the aesthetic quality of the front surface of the cooking apparatus.
To reduce the effect of the components on the aesthetic quality of the front surface of the cooking apparatus, in this embodiment, the air guide 300 may be provided at the cooking apparatus, as illustrated in
The air guide 300 may be disposed in the anterior gap described above. The air guide 300 may be disposed between the control panel 200 and the door 150, and provided to cover a portion of the font panel 120, the latch 140, the electronic components and the like from forward.
The air guide 300 may cover a portion of the anterior gap, between the control panel 200) and the door 150, and accordingly, a portion of the font panel 120, the latch 140, the electronic components and the like exposed to the front of the cooking apparatus through the anterior gap may be covered by the air guide 300.
In the case where the thickness of the air guide 300 increases, the area covered by the air guide 300 may expand. In the case where the area covered by the air guide 300 expands, the aesthetic quality of the front surface of the cooking apparatus may improve, making it difficult for air to be discharged to the front of the cooking apparatus through the anterior space S (see
In the case where the thickness of the air guide 300 decreases, the area covered by the air guide 300 may shrink. In the case where the area covered by the air guide 300 shrinks, improvement in the aesthetic quality of the front surface of the cooking apparatus may deteriorate, making it easy for air to be smoothly discharged to the front of the cooking apparatus through the anterior space S.
Considering this, the thickness of the air guide 300 may be set to a maximum one within the range where air is smoothly discharged to the front of the cooking apparatus through the anterior space S, preferably.
In the case where the thickness of the air guide 300 is set to satisfy the above-described conditions, the aesthetic quality of the front surface of the cooking apparatus may improve effectively, while the efficiency of discharging air through the anterior gap may be maintained at a certain level or above.
In this embodiment, a portion of the area exposed to the front of the cooking apparatus through the anterior gap may be covered by the air guide 300, ensuring improvement in the aesthetic quality of the front surface of the cooking apparatus.
In an example, the air guide 300 may be disposed in such a way that the first guide part 310 is disposed at the center of the anterior gap in the up-down direction, while being disposed in the anterior gap. That is, the air guide 300 may be disposed at a position (hereinafter, “central position”) where a distance between the first guide part 310 and the control panel 200 in the up-down direction and a distance between the first guide part 310 and the door 150 in the up-down direction are set to be the same, while the air guide 300 is disposed between the door 150 having closed the cooking compartment and the control panel 200.
Accordingly, the air guide 300 may form a structure that allows the first guide part 310 to cover the center of the anterior gap in the up-down direction thereof, i.e., to cover the anterior gap at the central position.
The air guide 300 allows the upper area of the anterior gap and the lower area of the anterior gap to be symmetrical to each other with respect to the first guide part 310, making the shape of the front surface of the cooking apparatus look reliable and ensuring improvement in the aesthetic quality of the front surface of the cooking apparatus.
Additionally, the air guide 300 in this embodiment may cover the lower area of the anterior gap through the second guide part 320 disposed at the rear side of the first guide part 310. At this time, the second guide part 320 is disposed at the rear side of the first guide part 310, and when viewed from forward, is less noticeable than the first guide part 310.
That is, the second guide part 320 may cover the lower area of the anterior gap at a position that is less noticeable than the position the first guide part 310.
While the air guide 300 having the second guide part 320 may cover the anterior gap in such a way that the upper area of the anterior gap is symmetrical to the lower area of the anterior gap with respect to the first guide part 310, the second guide part 320 less noticeable than the first guide part 310 may be used to cover the lower area of the anterior gap further.
The air guide 300 in this embodiment may make the shape of the front surface of the cooking apparatus look reliable and effectively ensure improvement in the aesthetic quality of the front surface of the cooking apparatus.
As described above, the air guide 300 may be coupled to the control panel 200 by the cover projection 210, 220.
In an example, the cover projection 210, 220 may comprise an outer cover projection 210.
The outer cover projection 210 may be provided to protrude downward from the lower end of the control panel 200. The outer cover projection 210 may be coupled to the air guide 300, under the control panel 200. Based on a coupling between the outer cover projection 210 and the air guide 300, the air guide 300 may be coupled to the control panel 200 while being spaced a predetermined distance apart from the lower end of the control panel 200.
Preferably, in the case where the outer cover projection 210 is coupled to the air guide 300, the air guide 300 may be disposed at the central position.
The outer cover projection 210 may be disposed at a position where at least a portion of the outer cover projection 210 covers at least a portion of the latch 140 from forward. For example, the outer cover projection 210 may protrude from the upper side of the latch 140 in the perpendicular direction thereof, while protruding downward from the lower end of the control panel 200.
The outer cover projection 210 disposed as described above covers at least a portion of the latch 140. Accordingly, when viewed from forward, at least a portion of the latch 140 is covered by the outer cover projection 210 and is not seen.
In an example, the outer cover projection 210 may be formed to protrude from the lower end of the control panel 200 up to the central position. Additionally, the width of the outer cover projection 210 may be set to be the width of the latch 140 or greater. The outer cover projection 210 may cover the upper half of the latch 140, exposed through the anterior gap, from forward. The lower half of the latch 140 may be exposed to the lower side of the air guide 300.
In this embodiment, the shape of the lateral surface of the latch 140 may be shaped into an approximate “¬” shape. The latch 140 may be formed in such a way that the upper end portion of the latch 140 protrudes forward. Accordingly, when viewed from forward, the upper half of the latch 140 has a shape more complex than the shape of the lower half of the latch 40.
While the outer cover projection 210 protrudes from the control panel 200 to have a length that is enough for the outer cover projection 210 to be coupled to the air guide 300, the outer cover projection 210 may protrude from the control panel 200 to have a length that is enough to cover the upper half of the latch 140.
That is, the outer cover projection 210 does not protrude to have a length that is greater than the length at which the outer cover projection 210 covers the upper half of the latch 140 as well as fixing the air guide 300 at the central position.
If the outer cover projection 210 protrudes further, a coupling structure between the outer cover projection 210 and the air guide 300 may become complex or their coupling itself may not occur, although the outer cover projection 210 covers the latch 140 further. Additionally, because of a structure protruding unnecessarily, the aesthetic quality of the front surface of the cooking apparatus may deteriorate.
Considering this, the outer cover projection 210 in this embodiment protrudes to have a length at which the outer cover projection 210 covers the upper half of the latch 140 as well as fixing the air guide 300 at the central position, without protruding in such a way that the outer cover projection 210 is long unnecessarily.
The outer cover projection 210 may help the upper half of the latch 140, which a portion significantly affecting the aesthetic quality of the front surface of the cooking apparatus, to be covered first, and help the air guide 300 at the central position, effectively ensuring improvement in the aesthetic quality of the font surface of the cooking apparatus.
In another example, the air guide 300 may be disposed at a position eccentric to the lower portion of the anterior gap from the center of the anterior gap in the up-down direction thereof, while being disposed in the anterior gap.
Considering that the height of the eye level of the user is ordinarily greater than the height of the air guide 300 disposed between the door 150 and the control panel 200, the user may identify the air guide 300 readily in the case where the air guide 300 is disposed at the position described above.
The air guide 300 needs to be disposed at a position where the air guide 300 is noticeable outside the cooking apparatus, such that the aesthetic quality provided by the air guide 300 is shown effectively.
That is, since the air guide 300 is disposed at a position eccentric to the lower portion of the anterior gap from the center of the anterior gap in the up-down direction, to embody an esthetic quality effectively.
In the case where the air guide 300 is disposed at the above-described position, the length of the cover projection 210, 220, in particular, the outer cover projection 210, in the up-down direction increases.
In the case where the length of the outer cover projection 210 increases, the outer cover projection 210 may cover an area greater than the upper half of the latch 140, while the outer cover projection 210 covers the latch 140. Since a greater portion of the latch 140 is covered by the outer cover projection 210 as described above, the aesthetic quality of the front surface of the cooking apparatus may improve effectively.
In this embodiment, the latch 140) is disposed at one side of the main body 100 in the lateral direction thereof, for example. For example, one latch 140 may be disposed at a position eccentric to one side of the main body 100 in the lateral direction thereof, in the cooking apparatus. At this time, the latch 140 may be disposed at a position more eccentric to one side of the main body 100 in the lateral direction thereof than the exhaust opening 122.
In this embodiment, a pair of outer cover projections 210 may be disposed between the control panel 200 and the air guide 300. The pair of outer cover projections 210 may be disposed in such a way that the pair of outer cover projections 210 is symmetrical to each other with respect to the center of the cooking compartment in the lateral direction thereof, i.e., the center of the main body 100 in the lateral direction thereof. To put it another way, the pair of outer cover projections 210 is disposed in such a way that the pair of outer cover projections 210 is symmetrical to each other with respect to the center of the control panel 200 in the lateral direction thereof.
One of the pair of outer cove projections 210 may be disposed at the front of the latch 140 and cover the upper half of the latch 140. The other of the pair of outer cover projections 210 is not disposed at the front of the latch 140.
Since the pair of outer cover projections 210 is symmetrically disposed as described above, the shapes of the cover projection 210, 220 and the air guide 300 that are exposed through the anterior gap may look balanced.
The cover projection 210, 220 may comprise an inner cover projection 220.
The inner cover projection 220 may be provided in such a way that the inner cover projection 220 protrudes downward from the lower end of the control panel 200. The inner cove projection 220 may be coupled to the air guide 300, under the control panel 200. Based on a coupling between the inner cover projection 220 and the air guide 300, the air guide 300 may be coupled to the control panel 200 while being spaced a predetermined distance apart from the lower end of the control panel 200.
Preferably, in the case where the inner cover projection 220 is coupled to the air guide 300, the air guide 300 may be disposed at the central position.
At least a portion of the inner cover projection 220 may be disposed at a position where at least a portion of the inner cover projection 220 covers at least a portion of the separation wall 121 from forward. For example, the inner cove projection 220 may protrude from the upper side of the separation wall 121 in the perpendicular direction thereof, while protruding downward from the lower end of the control panel 200.
The inner cover projection 220 disposed as described above covers at least a portion of the separation wall 121. Accordingly, when viewed from forward, at least a portion of the separation wall 121 is covered by the inner cover projection 220 and not be seen.
The inner cover projection 220 disposed as described above may be disposed between the pair of outer cover projections 210. For example, out of the plurality of cover projections 210, 220 arranged laterally, the outer cover projections 210 may be disposed at outermost sides laterally, and the inner cover projections 220 may be disposed between the outer cover projections 210.
The inner cover projection 220 and the outer cover projection 210 may allow the air guide 300 to be coupled to the cover projections 210, 220 at a plurality of points laterally and to be fixed to the lower portion of the control panel 200 reliably.
That is, the inner cover projection 220 may increase the number of coupling points between the control panel 200 and the air guide 300, and help the air guide 300 to be fixed reliably.
Additionally, the inner cover projection 220 may be disposed at a position where the inner cover projection 220 covers the separation wall 121 from forward, such that the number of vertical structures exposed through the anterior gap does not increase.
That is, the inner cover projection 220 may be disposed in such a way that the separation wall 121 as a vertical structure unavoidably exposed through the anterior gap is covered by the inner cover projection 220. As a result, apparently, the number of vertical structures exposed through the anterior gap does not increase.
Thus, the vertical structure exposed through the anterior gap may prevent deterioration in the aesthetic quality of the front surface of the cooking apparatus effectively.
Additionally, the inner cover projection 220 disposed as described above may be disposed at a position where the inner cover projection 220 avoids the exhaust opening 122. The exhaust opening 122 may form a passage required for air of the electronic component compartment 250 (see
Air drawn into the electronic component compartment 250 by the fan 260 (see
Under the assumption that the inner cover projection 220 is made of a plastic material, the inner cover projection 220 is highly likely to be thermally deformed, in the case where the inner cover projection 220 is ordinarily exposed to high-temperature air discharged through the exhaust opening 122.
For example, in the case where the inner cover projection 220 is disposed at the front of the exhaust opening 122 rather than being disposed at the front of the separation wall 121, the inner cove projection 220 may be thermally deformed due to the high-temperature air discharged through the exhaust opening 122.
Considering this, the inner cover projection 220 may be disposed at a position where the inner cover projection 220 avoids the exhaust opening 122, i.e., at the front of the separation wall 121 rather than the front of the exhaust opening 122, in this embodiment.
Accordingly, the thermal deformation of the inner cover projection 220 may be prevented effectively, and air may be discharged smoothly through the exhaust opening 122 without being interfering with by the inner cover projection 220.
That is, the inner cover projection 220 in this embodiment may be disposed at a position where the inner cover projection 220 covers the exhaust opening 122 from forward, such that the inner cover projection 220 may be disposed at a position where the inner cover projection 220 is less likely to be thermally deformed without interfering with the discharge of air through the exhaust opening 122, and a position where the aesthetic quality of the front surface of the cooking apparatus improves.
In summary, the air guide 300 disposed as described above, and the cover projection 210, 220 for fixing the air guide 300 produce the following effects.
First, a portion of the structures exposed through the anterior gap is covered by the air guide 300 providing a structure that covers the anterior gap while crossing the anterior gap laterally, ensuring improvement in the aesthetic quality of the front surface of the cooking apparatus.
In the case where the user looks at the anterior gap, the user's gaze is focused on the air guide 300 such that the user feels like the air guide 300 is only in the anterior gap because of an optical illusion, at the same time as the air guide 300 covers a portion of other structures at the rear of the air guide 300.
Additionally, since the air guide 300 may form a structure covering the anterior gap at a central position of the anterior gap, the upper area of the anterior gap and the lower area of the anterior gap may be symmetrical to each other, and the shape of the front surface of the cooking apparatus may look reliably.
Accordingly, the air guide 300 may help to improve the aesthetic quality of the front surface of the cooking apparatus effectively.
Second, at least a portion of a structure such as a latch 140 having a large complex shape may be covered by the outer cover projection 210, effectively ensuring improvement in the aesthetic quality of the front surface of the cooking apparatus.
In this embodiment, the upper half of the latch 140, which is a portion significantly affecting the aesthetic quality of the front surface of the cooking apparatus, may be covered by the outer cover projection 210 provided for fixing the air guide 300.
That is, since the outer cover projection 210 provided for fixing the air guide 300 is properly disposed at the front of the latch 140, the air guide 300 may be fixed reliably, and the aesthetic quality of the front surface of the cooking apparatus may improve.
Third, since the inner cover projection 220 may be disposed at a position where the inner cover projection 220 covers the separation wall 121 partitioning between the exhaust opening 122 and the exhaust opening 122 from forward, the inner cover projection 220 is less likely to be thermally deformed without interfering with discharge of air through the exhaust opening 122, and the aesthetic quality of the front surface of the cooking apparatus may improve.
Referring to
In this embodiment, the lower end of the front panel 120 and the cover projection 210, 220 are made of a plastic material, for example. Since the cover projection 210, 220 made of a plastic material is integrated with the lower end of the front panel 120, costs incurred for adding the cover projection 210, 220 may decrease, and the cover projection 210, 220 made of a plastic material may weigh much less than a cover projection 210, 220 made of a metal material.
The air guide 300 may be made of a metal material. In an example, the air guide 300 may be made of a metal material having excellent heat resistance and metallic luster. The air guide 300 may not be easily deformed despite high-temperature heat and not be easily damaged despite an impact, and its metallic luster may help to improve the aesthetic quality of the cooking apparatus.
Considering that the air guide 300 is disposed on a path in which high-temperature air is discharged, disposed at a noticeably position on the front surface of the cooking apparatus, and disposed at a position where the air guide 300 is frequently contacted by the user, the air guide 300 in this embodiment is made of a metal material.
The cover projection 210, 220 may be coupled to the fastening projection 330. Each of the cover projection 210, 220 may have a hollow hole, and the fastening projection 330 may have a fastening hole that is formed in such a way that the fastening hole penetrates the fastening projection 330 in the up-down direction, and communicates with the hollow hole. The cover projection 210, 220 and the fastening projection 330 may be coupled by a fastening member 305 such as a screw and the like.
Referring to
Specifically, external air may be drawn into the cooking apparatus through the lower portion of the main body 100. The external air drawn through the lower portion of the main body 100 may cool a variety of components, e.g., a motor for driving the convection part 160 and the like, disposed in the space at the rear side of the cooking apparatus, while passing through the space at the rear side of the cooking apparatus, where the convection part 160 and the like is disposed.
The air having moved upward by passing through the space at the rear side of the cooking apparatus may move to the electronic component compartment 250 through the space covered by the electronic component compartment 133, between the space at the rear side of the cooking apparatus and the electronic component compartment 250.
The air having moved into the electronic component compartment 250 may be suctioned by the fan 260 and drawn into the cooling flow path 255. The air drawn into the cooling flow path 255 may cool the electronic components in the electronic component compartment 250 while moving forward in the cooling flow path 255.
The air having moved forward in the electronic component compartment 250 may be discharged to the front of the electronic component compartment 250, i.e., the anterior space S, through the exhaust opening 122.
During a cooking process, air in the door 150, heated by heat transferred from the cooking compartment 130, may be discharged out of the door 150 through the door exhaust opening 152 provided at the upper end of the door 150.
As the hot air in the door 150 is discharged, external air at the lower side of the front of the cooking apparatus may be drawn into the door 150 through an air flow hole provided in the lower portion of the door 150 and move upward. In this process, the door 150 that is heated by heat transferred to the door 150 from the cooking compartment 130 may cool.
Additionally, the air, having moved upward in the door 150 while cooling the door 150, may be discharged to the anterior space S through the door exhaust opening 152. That is, the air discharged through the exhaust opening 122 and the air discharged through the door exhaust opening 152 may be discharged to the front of the cooking apparatus while being combined in the anterior space S.
In this embodiment, the anterior space S may be a space surrounded by the door 150, the front panel 120 and the control panel 200, and the air guide 300 may be disposed in the anterior space S.
The exhaust opening 122 may communicate with the anterior space S, at the rear side of the anterior space S, and the door exhaust opening 152 may communicate with the anterior space S, at the lower side of the anterior space S. Additionally, the anterior space S may be open toward the front of the cooking apparatus.
The door exhaust opening 152 may be disposed between the air guide 300 and the front panel 120. Specifically, the door exhaust opening 152 may be disposed at the front of the exhaust opening 122. That is, the door exhaust opening 152 may be disposed between the air guide 300 and the exhaust opening 122 with respect to the front-rear direction.
Additionally, the door exhaust opening 152 may be disposed at the lower sides of the air guide 300 and the exhaust opening 122. Further, the door exhaust opening 152 may be provided on the posterior part 150b while being provided at the upper end of the door 150.
Accordingly, the door exhaust opening 152 may be disposed at a position that is eccentric rearward on the door 150, and disposed further downward than an uppermost end of the door 150, formed by the anterior part 150a.
In a disposition relationship among the exhaust opening 122 and the door exhaust opening 152 and the air guide 300, the door exhaust opening 152 is disposed at a position closest to the exhaust opening 122 in the front-rear direction, on the door 150.
If the door exhaust opening 152 is disposed at the anterior part 150a of the door 150 rather than the posterior part 150b of the door 150, hot air discharged through the exhaust opening 122 is highly likely to flow reversely into the door 150 through the door exhaust opening 152.
Air discharged through the exhaust opening 122 moves to the front of the anterior space S while spreading in the anterior space S gradually. That is, air discharged through the exhaust opening 122 moves forward while spreading in the up-down direction as well as the front-rear direction in the anterior space S.
Accordingly, in the case where the door exhaust opening 152 is disposed further forward in the anterior space S, air discharged through the exhaust opening 122 is highly likely to be drawn toward the door exhaust opening 152. In the case where hot air discharged through the exhaust opening 122 flows reversely into the door 150 through the door exhaust opening 152, the door 150 may not cool smoothly, and heat drawn into the anterior space S may not be discharged smoothly out of the cooking apparatus.
Considering this, the door exhaust opening 152 may be disposed at the posterior part 150b of the door 150, and accordingly, the door exhaust opening 152 may be disposed at a position closest to the exhaust opening 122 in the front-rear direction, on the door 150, in this embodiment.
Thus, the door exhaust opening 152 may be disposed at a position where the door exhaust opening 152 escapes to a maximum degree from an area in which air discharged through the exhaust opening 122 flows, among positions in the front-rear direction, which may be selected in the door 150.
Further, in this embodiment, since the door exhaust opening 152 is disposed at the posterior part 150b, door exhaust opening 152 may be disposed further downward than an uppermost end of the door 150, formed by the anterior part 150a. That is, the door exhaust opening 152 may be disposed at a position that is far from the area in which air discharged through the exhaust opening 122 flows, in the downward direction.
Thus, the door exhaust opening 152 may be disposed at a position where the door exhaust opening 152 escapes to a maximum degree from the area in which air discharged through the exhaust opening 122 flows. The door exhaust opening 152 disposed as described above may help to suppress a reverse flow of hot air discharged to the anterior space S into the door 150 effectively.
Further, the door exhaust opening 152 may be disposed further rearward than the air guide 300, without being disposed at the lower side of the air guide 300 in the perpendicular direction thereof. Thus, the flow of air discharged from the door exhaust opening 152 may not be interfered with by the air guide 300, and the air may flow toward the anterior space S smoothly.
In this embodiment, the door exhaust opening 152 may be disposed between the air guide 300 and the front panel 120. That is, the air guide 300 may be disposed at the front sides of the exhaust opening 122 and the door exhaust opening 152. The air guide 300 may be disposed at a position that is eccentric forward in the anterior space S.
The air guide 300, disposed as described above, may guide the flow of air, discharged from the exhaust opening 122 and the door exhaust opening 152 to the anterior Space S, at the front side of the anterior space S.
For example, air discharged to the anterior space S respectively from the exhaust opening 122 and the door exhaust opening 152 may be discharged to the front of the cooking apparatus while being combined in the anterior space S. The air guide 300, as described above, may be disposed on a flow path (hereinafter, “discharge flow path”) of the air discharged from the anterior space S to the front of the cooking apparatus.
The air guide 300 disposed as described above may be shaped into a frame the width of which is greater than the length and thickness of the air guide 300 and the thickness of which is less than the length and width of the air guide 300.
The air guide 300 may partition a space between the control panel 120 and the door 150 into a first space S1 and a second space S2.
The first guide part 310 of the air guide 300 is disposed at the center of the anterior space S in the up-down direction thereof. Additionally, the second guide part 320 disposed at the rear side of the first guide part 310 blocks the second space S2, at the lower side of the first guide part 310.
Accordingly, air drawn into the anterior space S through the exhaust opening 122 may flow forward only through the first space S1 disposed at the upper side of the second space S2, without moving forward through the second space S2 blocked by the second guide part 320. Thus, air discharged from the exhaust opening 122 may be discharged to the front of the cooking apparatus through a space of the anterior space S, which is eccentric upward.
Additionally, air discharged from the door exhaust opening 152 may also flow forward only through the first space S1, without moving forward through the second space S2. Accordingly, the air discharged from the door exhaust opening 152 may move to a higher position than the second space S2 and then be discharged to the front of the cooking apparatus through a space of the anterior space S, which is eccentric upward.
Thus, air drawn to the anterior space S through the exhaust opening 122 and the door exhaust opening 152 may be combined in the anterior space S and move forward through the first space S1.
At this time, the air combined in the anterior space S after being discharged from the exhaust opening 122 and the door exhaust opening 152 as described above may be discharged to the front of the cooking apparatus while forming one flow passing through the first space S1, without being branched into a variety of flows by the air guide 300.
Additionally, the air forming the above-described flow may be discharged to the front of the cooking apparatus through a space of the anterior space S, which is eccentric upward.
In the case where the flow discharged forward from the anterior space S is separated in the up-down direction by the air guide 300, there may be a difference between the velocity of the flow of air passing through the upper side of the air guide 200 and the velocity of the flow of air passing through the lower side of the air guide 300.
In the case where the velocities of the two flows of the separated air differ, eddy current may occur at the front of the air guide 300.
In the case where eddy current occurs as described above, air drawn into the anterior space S may not be discharged properly out of the cooking apparatus, or air of the anterior space S may flow reversely into the door 150 through the door exhaust opening 152.
Considering this, air may flow only through one space formed at the upper side of the air guide 300, i.e., the first space S1, in this embodiment.
To this end, the air guide 300 of this embodiment may block the second space S2 through the second guide part 320, such that air is prevented from moving forward through the second space S2.
Accordingly, in the anterior space S, air may move forward only based one flow through the first space S1.
In the case where air moves forward only based one flow through the first space S1, it is much less likely to generate eddy current at the fronts of the air guide 300 and the cooking apparatus.
That is, the air guide 300 provided to block a space at the lower side of the air guide 300 may not allow the flow of air flowing through the discharge flow path to separate and may allow the same forward, ensuring a smooth discharge toward the front of the cooking apparatus.
Additionally, the air guide 300 may guide the flow of air such that air is discharged through the first space S1 of the anterior space S, which is eccentric to upward. The air guide 300 may guide the flow of air such that a distance between the flow of the air discharged and the door 150 increases.
Accordingly, since air is charged toward the front of the cooking apparatus, at a side of the anterior space S far away from the door 150, a distance between hot air discharged from the front of the cooking apparatus and the door 150 increases.
In the case where a distance between hot air discharged from the front of the cooking apparatus and the door 150 increases, reducing the possibility of an increase in the temperature of the door 150 based on contact between the hot air and the door 150.
Since air discharged from the exhaust opening 122 and the door exhaust opening 152 moves through a space of the anterior space S, which is eccentric upward, it is less likely that air discharged from the exhaust opening 122 moves downward and flows into the door 150 through the door exhaust opening 152 or it is less likely that air discharged from the door exhaust opening 152 flows reversely into the door 150 again.
Since the flow of air toward the front of the cooking apparatus is guided in the upward direction where the flow of the air becomes far away from the door exhaust opening 152, air drawn into the anterior space S is much less likely to be drawn into the door 150.
To this end, the second guide part 320 may block the flow of air through a space adjacent to the door exhaust opening 152 by blocking the second space S2 adjacent to the door exhaust opening 152.
Additionally, the second guide part 320 may form a blocking wall that inclines forward and upward, to guide an upward movement of air drawn into the anterior space S.
The air guide 300 of this embodiment, as described above, may effectively suppress a reverse flow of air discharged out of the electronic component compartment or the door 150 into the door 150 as well as effectively suppressing an increase in the temperature of the door 150 cause by hot air discharged to the front of the cooking compartment.
Referring to
At this time, since the second guide part 320 is disposed at the upper side of the posterior part 150b, at least a portion of the second guide part 320 may contact the posterior part 150b, at the upper side of the posterior part 150b. That is, the second guide part 320 may contact the posterior part 150b at a position where the second guide part 320 overlaps the posterior part 150b in the up-down direction.
In the case where the second guide part 320 contacts the posterior part 150b as described above, the gap between the air guide 300 and the door 150 in the second space S2 may be blocked. Accordingly, a forward movement of air through the second space S1 may be effectively prevented by the second guide part 320.
In this embodiment, the posterior part 150b may be shaped into an inclination surface that inclines downward toward the rear of the posterior part 150b. Additionally, the second guide part 320 may be shaped into an inclination surface parallel with the posterior part 150b.
Accordingly, at least a portion of the second guide part 320 may contact the posterior part 150b while forming an inclination surface parallel with the inclination surface of the posterior part 150b. The second guide part 320 and the posterior part 150b may contact each other at a position where the second guide part 320 and the posterior part 150b overlap each other in the up-down direction, and at this time, a contact surface between the second guide part 320 and the posterior part 150b may form an inclination surface that inclines downward toward the rear of the contact surface.
Additionally, since the contact surface between the second guide part 320 and the posterior part 150b is formed to incline as described above, at least a portion of the second guide part 320 may contact the posterior part 150b at a lower position than the upper end of the anterior part 150a.
To the end, the second guide part 320 may have a length at which the lower end of the second guide part 320 reaches a lower position than the upper end of the anterior part 150a.
In an example, the length of the second guide part 320 in the up-down direction may be set to a length at which the second guide part 320 reaches a position where the lower end of the second guide part 320 is lower than the upper end of the anterior part 150a and higher than the upper end of the door exhaust opening 122.
Additionally, the length of the second guide part 320 in the front-rear direction may be set to a length at which the rear end of the second guide part 320 is disposed between the anterior part 150a and the door exhaust opening 150b. At this time, the rear end of the second guide part 320 may be disposed between the rear end of the anterior part 150a and the door exhaust opening 150b, with respect to the front-rear direction.
Accordingly, the second guide part 320) and the posterior part 150b may contact each other at a position where the second guide part 320 and the posterior part 150b overlap each other in the up-down direction and the front-rear direction.
Since the second guide part 320 and the posterior part 150b contact each other in this way, the gap between the air guide 300 and the door 150 in the second space S2 may be blocked effectively.
In the case where the shape and length of the second guide part 320 are set as described above and the contact surface between the second guide part 320 and the posterior part 150b is formed to incline, any portion of the second guide part 320 may not overlap a range in which the door 150 moves, while the second guide part 320 is disposed at a position where the second guide part 320 overlaps at least a portion of the door 150 in the up-down direction.
Thus, the second guide part 320 may contact the door 150 at a position where the second guide part 320 does not interfere with the movement of the door 150. The second guide part 320 may block the second space S2 while blocking the gap between the air guide 300 and the door effectively, without interfering with the door 50's movement for opening and closing.
Additionally, the inner cover projection 220 fixing the air guide 300 to the control panel 200, as illustrated in
The inner cover projection 220 may be disposed at a position where the inner cover projection does not overlap the exhaust opening 122, while covering the separation wall 121 from the front of the separation wall 121 (see
Further, the end portion 301 of the front of the air guide 300 disposed at the front side of the anterior space S in the anterior space S, i.e., the end portion 301 of the front of the first guide part 310, as described above, may be disposed at a position where the end portion of the front of the air guide 300 overlaps at least a portion of the front glass 153 of the door 150 in the up-down direction.
In an example, the end portion 301 of the front of the air guide 300 may be disposed at the same position as the rear end of the front glass 152, or at a position protruding further forward than the rear end of the front glass 152, with respect to the front-rear direction.
Since the air guide 300 is disposed as described above at a position that is eccentric forward in the anterior space S, the flow of air flowing toward the front of the cooking apparatus in the anterior space S may be guided by the air guide 300 effectively.
Additionally, since the air guide 300 is disposed as described above at a position where the air guide 300 is noticeable outside the cooking apparatus, the aesthetic quality provided by the air guide 300 may be shown effectively.
In the process of discharging hot air from the anterior space S, a portion of the air discharged may contact the lower end of the control panel 200, and accordingly, condensed water may be formed at the lower end of the control panel 200.
In the case where the condensed water formed at the lower end of the control panel 200) as described above drops to the upper end of the door 150, the water having hit the door 150 splashes around the door 150 and contaminates surroundings thereof.
In the case where the air guide 300 is disposed at a position that is eccentric forward in the anterior space S as described above, the air guide 300 may block between the control panel 200 and the door 150 such that the condensed water formed at the lower end of the control panel 200 does not fall to the door 150.
Since the distance between the control panel 200 and the air guide 300 is much less than the distance between the control panel 200 and the door 150, the amount of the water splashing around the air guide is not that great, even if the condensed water drops to the air guide 300.
That is, the air guide 300 disposed in the above-described way may significantly reduce the occurrence of contamination around the cooking apparatus, caused by the condensed water.
Additionally, in the case of an air guide 300 of this embodiment, the second guide part 320 is formed to incline downward and rearward. Accordingly, the condensed water falling to the air guide 300 may flow down the rear side of the door 150 along the inclination surface of the second guide part 320.
In particular, in the case where the first guide part is formed to incline downward and rearward like the air guide 300a illustrated in
Since the air guide allows the condensed water falling toward the door 150 to flow down the rear side of the door 150 as described above, the occurrence of contamination around the cooking apparatus, caused by the condensed water, may decrease effectively.
Further, the end portion 303 of the rear of the air guide 300, i.e., the end portion 303 of the rear of the second guide part 320, may be disposed further forward than the door exhaust opening 152, with respect to the front-rear direction.
Accordingly, a passage having an enough height may be formed between the door exhaust opening 152 and the air guide 300, to discharge air in the door 150 to the anterior space S through the door exhaust opening 152.
Thus, air discharged from the door exhaust opening 152 and air discharged from the exhaust opening 112 may be combined sufficiently and then pass through the section where the air guide 300 is disposed.
Additionally, in the case where the end portion of the rear of the air guide 300 is disposed at the above-described position, the air guide 300 does not act as an obstacle that is disposed perpendicularly over the door exhaust opening 152. The air guide 300 may reduce flow resistance effectively around the door exhaust opening 152.
In another example, the end portion 301 of the front of the air guide 300 may be disposed at a position where the end portion 301 of the front of the air guide 300 is aligned with the position of at least any one of the end portion of the front side of the control panel 200 and the end portion of the front side of the door 150 in the front-rear direction.
For example, when viewed laterally, the end portion 301 of the front of the air guide 300 and the edge of the lower end of the front side of the control panel 200 may be disposed on the same line. Additionally, when viewed laterally, the end portion 301 of the front of the air guide 300 and the edge of the upper end of the front side of the door 150 may be disposed on the same line.
Since the air guide 300 is disposed as described above, the positions of the control panel 200 and the air guide 300 and the door 150 are aligned, such that the exterior of the cooking apparatus looks balanced, ensuring improvement in the aesthetic quality of the cooking apparatus.
The improvement in the aesthetic quality of the cooking apparatus may be ensured by disposing the air guide 300 eccentrically toward the front side of the anterior space S, in the anterior space S.
That is, the air guide 300 of this embodiment is disposed eccentrically toward the front side of the anterior space S, in the anterior space S, producing the effects of suppressing the occurrence of eddy current in the anterior space S and ensuring improvement in the aesthetic quality of the cooking apparatus.
