Hereinafter, embodiments of the present disclosure will be described in detail through exemplary drawings. In describing embodiments of the present disclosure, detailed descriptions of related known components or functions will be omitted if they are judged to be obvious to those skilled in the art.
In addition, it should be noted in advance that, for convenience of explanation and understanding, the following embodiments only illustrate a refrigerator in which the refrigerating chamber is provided above the freezing chamber, and the present disclosure is not limited thereto, and the present disclosure is applicable to all types of refrigerators in which ducts can be placed on the rear surface and the upper surface of the storage space.
Before explaining, the direction is defined. In an embodiment of the present invention, the direction toward the open entrance of the storage space illustrated in
As illustrated, the refrigerator 1 according to an embodiment of the present disclosure includes a cabinet 10 in which a storage space is formed and a door 20 that opens and closes the storage space.
For example, the storage space may be divided up and down, with a refrigerating chamber 11 formed at the upper portion and a freezing chamber 12 formed at the lower portion. For example, the refrigerating chamber 11 may be referred to as a first storage space, and the freezing chamber 12 may be referred to as a second storage space.
Additionally, the door 20 may include a refrigerating chamber door 21 that opens and closes the refrigerating chamber 11 and a freezing chamber door 22 that opens and closes the freezing chamber 12. The refrigerating chamber door 21 may be referred to as a first door, and the freezing chamber door 22 may be referred to as a second door. For example, the refrigerating chamber door 21 may be rotatably mounted on the cabinet 10 to open and close the refrigerating chamber 11. In addition, a pair of refrigerating chamber doors 21 are provided on both left and right sides, so that the pair of refrigerating chamber doors can partially open and close the refrigerating chamber, respectively. Additionally, the freezing chamber door 22 may be rotatably mounted on the cabinet 10 to open and close the freezing chamber 12. In addition, a pair of freezing chamber doors 22 are provided on both left and right sides, so that the pair of freezing chamber doors can partially open and close the freezing chamber, respectively.
Of course, the present disclosure is not limited to the storage space and door shape and may be applied to various types of refrigerators.
The refrigerating chamber 11 and the freezing chamber 12 can be cooled by cold air supplied from the evaporator 13. As an example, the evaporator 13 may include a refrigerating chamber evaporator provided in the refrigerating chamber 11 and a freezing chamber evaporator provided in the freezing chamber 12. As another example, the evaporator 13 may be provided only in the freezing chamber 12, and the cold air from the evaporator 13 may be supplied to both the refrigerating chamber 11 and the freezing chamber 12.
The storage space may be provided with a cold air duct that guides the cold air generated from the evaporator 13 into the storage space. As an example, the cold air duct may include a first duct 15 and a second duct 16.
The rear wall of the refrigerating chamber 11 may be provided with a first duct 15 that moves cold air generated in the refrigerating chamber evaporator 13 upward. The first duct 15 may be referred to as a rear duct or a refrigerating chamber duct. The first duct 15 may be covered by the rear wall of the refrigerating chamber 11, and an insulating material may be disposed on at least a portion of the front of the first duct 15. In other words, at least a portion of the first duct 15 may be insulated.
The inside of the first duct 15 may be divided into multiple flow paths and may be referred to as a multi-duct. In addition, the first duct 15 may include a duct cover 110 that forms the rear surface of the refrigerating chamber 11. A plurality of rear discharge ports 111 may be formed in the first duct 15. The rear discharge port 111 may pass through the duct cover 110, open toward the refrigerating chamber 11, and discharge cold air flowing through the first duct 15 forward. The rear discharge port 111 may be referred to as a first discharge port.
A blowing fan 14 is provided at the rear of the first duct 15 to force air flow inside the first duct 15. The blowing fan 14 may be provided on one side communicating with the first duct 15. The blowing fan 14 may be provided on one side of the refrigerating chamber evaporator 13. Additionally, cold air can be circulated between the refrigerating chamber evaporator 13 and the refrigerating chamber 11 by driving the blowing fan 14.
The first duct 15 may extend to the upper end of the rear surface of the refrigerating chamber 11 and communicate with the second duct 16. The second duct 16 may be referred to as an upper duct or a door cooling duct.
The second duct 16 may be provided on the upper surface of the refrigerating chamber 11. The second duct 16 may extend forward from the rear end of the upper surface of the refrigerating chamber 11. The front end of the second duct 16 may extend to a position adjacent to the front end of the refrigerating chamber 11. Additionally, an upper discharge port 122 that discharges cold air may be formed in the second duct 16. The upper discharge port 122 may be referred to as a second discharge port. The upper discharge port 122 may be exposed to the upper surface 120 of the refrigerating chamber 11. The upper discharge port 122 may be positioned above the door storage space 211 provided at the rear surface of the refrigerating chamber door 21.
As an example, the door storage space 211 may have a basket structure. If necessary, the door storage space 211 may be a separate storage space provided at the rear surface of the refrigerating chamber door 21.
The door storage space 211 may protrude rearward from the rear surface of the refrigerating chamber door 21. Additionally, the door storage space 211 may be positioned below the upper discharge port 122. Accordingly, cold air discharged from the second duct 16 can be supplied to the door storage space 211.
The rear end of the second duct 16 may be connected to the upper end of the first duct 15. Therefore, cold air flowing along the first duct 15 may be guided to the second duct 16. Additionally, cold air flowing along the second duct 16 may be supplied downward from one side of the front end of the upper surface of the refrigerating chamber 11 and directed to the inside of the refrigerating chamber 11. In addition, some of the cold air discharged from the upper discharge port 122 of the second duct 16 may be directed to the door storage space 211.
The suction port 112 that suctions air from the refrigerating chamber toward the evaporator 13 may be positioned at the lower end of the rear wall of the refrigerating chamber 11. Accordingly, the suction port 112 may be disposed diagonally from the cold air discharged from the second duct 16 and the deodorizing discharge port 333 of the deodorizing device 30, which will be described below. Accordingly, overall circulation of cold air and deodorization/sterilization air may be possible within the refrigerating chamber 11.
As illustrated in the drawing, the cabinet 10 may include an outer case 101 that forms the outer appearance, and an inner case 102 that is spaced apart from the outer case 101 and forms the storage space. Additionally, an insulating material 103 may be filled between the outer case 101 and the inner case 102.
A lighting device 17 may be provided on the upper surface of the refrigerating chamber 11 to illuminate the refrigerating chamber 11. Additionally, a deodorizing device 30 may be provided on the upper surface of the refrigerating chamber 11 to provide deodorized air into the refrigerating chamber 11. The deodorizing device 30 may be a device capable of deodorizing as well as sterilizing.
In addition, the second duct 16 may be provided inside the upper surface of the refrigerating chamber 11. The second duct 16 may be provided between the inner case 102 and the inner case 102 above the refrigerating chamber 11. Accordingly, the second duct 16 may be at least partially embedded in the insulating material 103.
The front end of the second duct 16 may communicate with the upper surface of the refrigerating chamber 11 to form the upper discharge port 122. The upper discharge port 122 may extend long from the upper surface of the refrigerating chamber 11 in the left and right direction. The upper discharge port 122 may be positioned somewhat rearward than the front end of the refrigerating chamber 11 and may be positioned forward of the deodorizing device 30. In addition, the upper discharge port 122 may be positioned between the lighting device 17 that illuminates the refrigerating chamber 11 and the deodorizing device 30.
A first inclined surface 121 may be formed in a portion of the inner case 102 that forms the front end of the refrigerating chamber 11. The first inclined surface 121 may become lower toward the rear, and may form a space into which a portion of the circumference of the refrigerating chamber door 21 is inserted when the refrigerating chamber door 21 is closed.
The lighting device 17 may be provided at the end portion of the first inclined surface 121. The lighting device 17 may extend long in the left and right directions, together with a plurality of LEDs, and may include a cover 172 through which light is transmitted. The cover 172 may shield the LED 171. One surface of the lighting device 17, that is, the surface of the cover 172 through which light transmits, may form a second inclined surface 173. The second inclined surface 173 may have a slope that increases toward the rear. Accordingly, the lighting device 17 is provided at the front end of the upper surface of the refrigerating chamber 11, but can illuminate the entire storage space.
The upper discharge port 122 may be provided at the rear of the lighting device 17. The upper discharge port 122 may be positioned at the same height as the rear end of the lighting device 17. Therefore, when viewed from the front by the user, direct exposure of the upper discharge port 122 can be prevented. At this time, the upper discharge port 122 may be positioned in an area vertically above the door storage space 211.
The deodorizing device 30 may be provided behind the upper discharge port 122. The deodorizing device 30 is positioned behind the upper discharge port 122, but may be positioned significantly forward with respect to the center of the upper surface of the refrigerating chamber 11. Therefore, the deodorizing device 30 can be expressed as being positioned in the first half or the front end of the upper surface of the refrigerating chamber 11.
The deodorizing device 30 may be mounted on the upper surface of the refrigerating chamber 11, and in this case, the lower end of the deodorizing device 30 may be positioned to be higher than the lower end of the first inclined surface 121 or the second inclined surface 173. Therefore, when the user views from the front, the deodorizing device 30 may not be exposed, or only a minimal portion of the deodorizing device 30 may be visible.
The deodorizing device 30 may be disposed so that at least a portion of the deodorizing device 30 is positioned higher than the upper surface of the refrigerating chamber 11. Additionally, the deodorizing device 30 may be disposed so that at least a portion of the deodorizing device 30 protrudes toward the inside of the refrigerating chamber 11.
A deodorizing discharge port 333 may be formed in the deodorizing device 30, and deodorized air may be supplied to the refrigerating chamber 11. The deodorizing discharge port 333 may be referred to as a third discharge port. At this time, the deodorizing device 30 is positioned close to the front end of the upper surface of the refrigerating chamber 11, so that when the user opens the refrigerating chamber door 21 and approaches to the refrigerating chamber, the user can be in contact with the deodorizing and sterilized air, thereby preventing the user from being exposed to odors or bacteria.
The above drawing only illustrates the location of the deodorizing device 30, and the deodorizing device 30 may have various structures and dispositions. Below, various examples of the disposition and structure of the deodorizing device 30 will be described.
As illustrated, a lighting device 17 may be provided on the upper surface of the refrigerating chamber 11, and the upper discharge port 122 may be positioned at the rear end of the lighting device 17. Additionally, the second duct 16 may be disposed between the outer case 101 and the inner case 102.
Due to the disposition of the second duct 16, the insulation thickness of the upper surface of the refrigerating chamber 11 is reduced, and, to compensate for this, an additional insulating material 104 may be disposed above the second duct 16. The additional insulating material 104 may be an insulating material that has a higher insulation coefficient or has better insulation performance compared to the insulating material. As an example, the additional insulating material 104 may be a vacuum insulating material (VIP).
The deodorizing device 30 may be connected to the second duct 16 at the upper surface of the refrigerating chamber 11. Additionally, the deodorizing device 30 can deodorize and sterilize the air flowing through the second duct 16.
In detail, the deodorizing device 30 may include a deodorizing filter 32. The deodorizing filter 32 may be provided inside the second duct 16. Additionally, the deodorizing filter 32 may be positioned on a path through which cold air flows in the second duct 16.
The deodorizing filter 32 may contain a deodorizing agent capable of trapping or removing odor factors. Additionally, the deodorizing filter 32 may be composed of multiple layers containing various deodorizing agents overlapping one another.
The deodorizing filter 32 may be configured to divide at least a portion of the inside of the second duct 16. Accordingly, the air flowing through the second duct 16 can be deodorized while passing through the deodorizing filter 32.
The deodorizing device 30 may include a sterilization LED 161. The sterilization LED 161 may be fixed to one side of the second duct 16 and may irradiate light toward the deodorizing filter 32. For example, the sterilization LED 161 may be an LED that irradiates ultraviolet rays, and may sterilize bacteria in the deodorizing filter 32. In addition, the sterilization LED 161 can activate the catalyst of the deodorization filter 32 to enable deodorization and sterilization more smoothly.
The sterilization LED 161 is provided in the second duct 16, and when the deodorizing device 30 is separated, the sterilization LED may be in a state of being mounted in the second duct 16 separately from the deodorizing filter 32 and the deodorizing device cover 33. Therefore, there is an advantage in that the sterilization LED is easy to dispose and service wires.
The deodorizing device 30 may include a filter mounting part 31. The filter mounting part 31 is for fixing the deodorizing filter 32 and can be coupled to the second duct 16 or the deodorizing device cover 33. Accordingly, the filter mounting part 31 may be configured as a separate structure and coupled to the second duct 16 or the deodorizing device cover 33. Additionally, the filter mounting part 31 may be formed integrally with the second duct 16 or the deodorizing device cover 33.
The deodorizing filter 32 may be disposed at an angle based on the upper surface of the refrigerating chamber 11 by the filter mounting part 31. Additionally, the deodorizing filter may be disposed at an angle so as to cross the direction of air flow through the second duct 16. Accordingly, the air flowing along the second duct 16 can easily pass through the deodorizing filter 32. In addition, the filter mounting part 31 can maintain a gap between the deodorizing filter 32 and the deodorizing device cover 33.
Accordingly, it is possible to secure a flow space in which the air that has passed through the deodorizing filter 32 can be smoothly discharged through the deodorizing cover 172. One surface of the deodorizing filter 32 and the deodorizing device cover 33 may be disposed to have different inclinations by the filter mounting part 31.
The deodorizing filter 32 may be positioned between the second duct 16 and the upper discharge port 122. Accordingly, the air deodorized by the deodorizing filter 32 may be supplied to the refrigerating chamber 11 through the upper discharge port 122.
The deodorizing device 30 may include a deodorizing device cover 33. The deodorizing device cover 33 may be mounted on the end portion of the second duct 16. In addition, the deodorizing device cover may protrude from the inner case 102 forming the upper surface of the refrigerating chamber 11.
The deodorizing device cover 33 may be disposed between the upper discharge ports 122. The upper discharge port 122 may be disposed on both left and right sides of the deodorizing device cover 33. Additionally, the deodorizing device cover 33 may be disposed so that at least a portion of the deodorizing device cover overlaps the upper discharge port 122. Additionally, the deodorizing device 30 may partially communicate with the upper discharge port 122.
The deodorizing device cover 33 is provided below the deodorizing filter 32 and can shield the deodorizing filter 32. The deodorizing device cover 33 may further shield the end portion of the second duct 16.
The deodorizing device cover 33 may include a first surface 331 and a second surface 332 that are exposed when mounted on the upper surface of the refrigerating chamber 11. The first surface 331 may extend rearward from the front end of the deodorizing device cover 33. The first surface 331 may be in contact with the rear end of the lighting device 17. The first surface 331 shields the deodorizing filter 32 from below and may extend rearward to pass through the area of the deodorizing filter 32. Additionally, the first surface 331 may be formed to become lower as it extends rearward, forming the third inclined surface 331.
The third inclined surface 331 is disposed to be inclined in the same direction as the first inclined surface 121, but may have a greater inclination than the first inclined surface 121. In addition, the first surface 331 may be formed to be inclined in a direction that crosses the second inclined surface 173 of the lighting device 17. Accordingly, the light emitted from the LED 171 of the lighting device 17 may be irradiated onto the first surface 331 of the deodorizing device cover 33. Accordingly, the first surface 331 can be highlighted by the lighting device 17, and thus the deodorizing function can be emphasized to the user.
The extended rear end of the first surface 331 may be the lowest part of the deodorizing device 30. Additionally, the rear end of the first surface 331 may be the position that protrudes most from the upper surface of the refrigerating chamber 11. At this time, the extended rear end of the first surface 331, that is, the lower end of the deodorizing device 30, may be positioned higher than the lower end of the first inclined surface 121 and the lower end of the second inclined surface 173. Accordingly, it is possible to prevent excessive exposure or protrusion of the deodorizing device 30 when viewed from the front by the user.
The second surface 332 may be bent at the rear end of the first surface 331. The second surface 332 may extend in a direction crossing the first surface 331. The second surface 332 extends rearward from the rear end of the first surface 331 and may extend upward. In other words, the second surface 332 may have an upward slope as the second surface extends rearward. In addition, the rear end of the second surface 332 may be in contact with the inner case 102.
A deodorizing discharge port 333 may be formed on the second surface 332. The deodorizing discharge port 333 passes through the second surface 332 and may be opened to face rearward. Accordingly, the air passing through the deodorizing filter 32 may be discharged toward the inside of the refrigerating chamber 11. In addition, the opening direction of the deodorizing discharge port 333 may cross the opening direction of the upper discharge port 122. Accordingly, cold air discharged through the second duct 16 may be simultaneously discharged in one direction through the upper discharge port 122 and in another direction through the deodorizing discharge port 333. At this time, the discharge direction of the deodorizing discharge port 333 may be toward the center of the refrigerating chamber 11.
In addition, the deodorizing device cover 33 can be separated from the deodorizing filter 32 by a sufficient distance due to the inclined structure of the first surface 331 and the second surface 332, and a flow space can be secured so that the air that has passed through the deodorizing filter 32 can be smoothly discharged toward the center of the refrigerating chamber 11.
Meanwhile, the cold air generated for the evaporator 13 flows along the first duct 15 and the second duct 16 by driving the blowing fan 14, passes through the deodorizing device 30, and may be discharged into the refrigerating chamber 11. Therefore, it is possible to supply deodorized air to the refrigerating chamber 11 without a separate fan for deodorization. In other words, since a flow structure for deodorization can exist on the cold air supply system in the refrigerator, there is an advantage of reducing unnecessary configuration and reducing power consumption.
In addition, the odor factor in the air, which is primarily deodorized by removing in the very low-temperature evaporator 13, does not spread because the odor factor flows through the insulated first duct 15 and second duct 16, and the odor factor in the air when the temperature is still low may be discharged in a finally deodorized state from the deodorizing device 30 disposed at the end of the cold air flow path.
Accordingly, when the refrigerating chamber door 21 is opened, the user positioned in the front surface of the refrigerating chamber 11 is exposed to a cold air environment in a deodorized state, and thus discomfort caused by odor can be prevented.
Additionally, cold air deodorized and discharged from the front end of the upper surface of the refrigerating chamber 11 may be suctioned into the lower end of the rear surface of the refrigerating chamber 11 and flow into the evaporator 13. Therefore, the path on the upper discharge port 122 and the suction port 112, which are diagonally separated from each other, can be a path crossing the refrigerating chamber 11, and the cooling efficiency and deodorizing efficiency of the refrigerating chamber 11 can be maximized.
Meanwhile, the present disclosure may have various other embodiments in addition to the above-described embodiments. Hereinafter, another embodiment of the present disclosure will be described in detail with reference to the drawings. In addition, since configurations not described below are the same as the above-described embodiments, detailed descriptions and illustrations thereof are omitted to prevent duplication of description, and the configurations not described below are described using the same reference numerals. In other words, hereinafter, only the configuration that differs from the above-described embodiment will be described in detail.
As illustrated, the cabinet 10 of the refrigerator 1 according to the second embodiment of the present disclosure is composed of an outer case 101 and an inner case 102, and the inside thereof may be filled with insulating material 103.
In addition, a lighting device 17 may be provided on the upper surface 120 of the refrigerating chamber 11, and the upper discharge port 122 may be positioned at the rear end of the lighting device 17. Additionally, the second duct 18 may be disposed between the outer case 101 and the inner case 102. The second duct 18 may be embedded in the insulating material 103.
Additionally, the deodorizing device 40 may be provided behind the upper discharge port 122. The deodorizing device 40 may be disposed adjacent to the front end of the upper surface 120 of the refrigerating chamber 11. Additionally, the deodorizing device 40 may be placed adjacent to the upper discharge port 122.
The deodorizing device 40 may be mounted on the inner case 102 forming the upper surface 120 of the refrigerating chamber 11. In addition, the inner case 102 may be formed with a recessed part 124 to accommodate at least a portion of the deodorizing device 40.
Accordingly, at least a portion of the deodorizing device 40 may be disposed upward with respect to the upper surface of the refrigerating chamber 11. The deodorizing device 40 may be positioned below the second duct 18. Accordingly, the deodorizing device 40 can be inserted into the space formed between the second duct 18 and the inner case 102.
In addition, at least a portion of the deodorizing device 40 may protrude downward from the upper surface of the refrigerating chamber 11. At this time, the protruding lower end of the deodorizing device 40 may be positioned higher than the lower ends of the first inclined surface 121 and the second inclined surface 173. Accordingly, when viewed from the front, at least a portion of the deodorizing device 40 may be covered by the first inclined surface 121 or the second inclined surface 173.
The deodorizing device 40 may be disposed in the front half of the refrigerating chamber 11 adjacent to the lighting device 17. Therefore, the light irradiated through the second surface 332 of the lighting device 17 can illuminate a portion of the deodorizing device 40, and when viewed by the user, the portion of the deodorizing device 40 may be emphasized.
The deodorizing device 40 may include a deodorizing fan 43, a deodorizing filter 42, and a deodorizing device cover 41.
The deodorizing device cover 41 may be mounted on the inner case 102 and form the outer appearance of the deodorizing device 40. In addition, the deodorizing device cover 41 may shield the deodorizing fan 43 and the deodorizing filter 42.
The lower surface of the deodorizing device cover 41 may be formed in a planar shape parallel to the upper surface of the refrigerating chamber 11. The lower surface of the deodorizing device cover 41 may be positioned higher than the lower end of the first inclined surface 121 or the second inclined surface 173.
A deodorizing device suction port 412 and a deodorizing device discharge port 413 may be formed on the circumferential surface of the deodorizing device cover 41. The deodorizing device suction port 412 and the deodorizing device discharge port 413 may be formed along the circumferential surface of the deodorizing device cover 41. A plurality of the deodorizing device suction port 412 and the deodorizing device discharge port 413 may be formed along the deodorizing device cover 41.
For example, the deodorizing device suction port 412 may be positioned higher than the deodorizing device discharge port 413. In addition, at least some of the deodorizing device suction port 412 may be disposed adjacent to the upper discharge port 122. Therefore, the cold air discharged from the upper discharge port 122 can immediately flow into the deodorizing device suction port 412 and be deodorized.
A deodorizing filter mounting part 411 may be formed on the deodorizing device cover 41. The deodorizing filter mounting part 411 may be disposed between the deodorizing device suction port 412 and the deodorizing device discharge port 413 and may allow the deodorizing filter 42 to be fixedly mounted.
Additionally, the deodorizing fan 43 may be provided above the deodorizing filter 42. The deodorizing fan 43 may be configured as a box fan structure. Therefore, when the deodorizing fan 43 is driven, the air suctioned into the deodorizing device suction port 412 may pass through the deodorizing filter 42, the air passing through the deodorizing filter 42 pass through the deodorizing device discharge port 413, and be discharged into the refrigerating chamber 11.
In addition, the deodorizing device 40 may further include a sterilization LED 44. The sterilization LED 44 may be provided between the deodorizing fan 43 and the deodorizing filter 42, and may irradiate light toward the deodorizing filter 42. The deodorizing performance of the deodorizing filter 42 is activated by the sterilization LED 44 and thus sterilization becomes possible. The structure of the deodorizing filter 42 and the sterilization LED 44 may be the same as the above-described embodiment.
Meanwhile, the cold air generated in the evaporator 13 may flow along the first duct 15 and the second duct 18 by driving the blowing fan 14, flow through the upper discharge port 122, and be discharged into the refrigerating chamber 11.
Additionally, the cold air discharged from the upper discharge port 122 may flow into the adjacent deodorizing device 40, be deodorized, and then be discharged back into the refrigerating chamber 11. At this time, the upper discharge port 122 and the deodorizing device suction port 412 are so close that the cold air discharged from the second duct 18 can substantially directly pass through the deodorizing device 40. The upper discharge port 122 and the deodorizing device suction port 412 may have a structure that communicates with each other.
Therefore, the odor factor in the air that is primarily deodorized by being removed in the evaporator 13, which has a very low temperature, does not spread because the odor factor flows through the insulated first duct 15 and the second duct 18, and the odor factor in the air, which is still at a low temperature, may be discharged in a finally deodorized state from the deodorizing device 40 disposed at the end of the cold air flow path.
Accordingly, when the refrigerating chamber door 21 is opened, the user positioned in the front surface of the refrigerating chamber 11 is exposed to a cold air environment in a deodorized state, and thus discomfort caused by odor can be prevented.
In addition, the cold air deodorized and discharged through the deodorizing device 40 at the front end of the upper surface of the refrigerating chamber 11 may be suctioned into the suction port 112 at the lower end of the rear surface of the refrigerating chamber 11 and flow into the evaporator 13 to be circulated.
