DETAILED DESCRIPTION

FIGS. 1 through 17, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged device. Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings.

FIG. 1 is a perspective view of a gas oven in accordance with a first embodiment of the present disclosure. FIG. 2 is a perspective view illustrating an inside of the gas oven in accordance with the first embodiment of the present disclosure.

Referring to FIGS. 1 and 2, a gas oven 1 includes a cooking space 40 that is provided inside a body 10 and accommodates ingredients, a plurality of burners 61 that generates heat by burning gas, and a plurality of convection fans 51 and 52 that convect air in the cooking space 40.

The cooking space 40 is formed in an approximate box shape that includes a top wall 31, a bottom wall 32, a left sidewall 33, and a right sidewall 34, and a rear wall 35 as inner walls thereof, and an open front to withdraw and insert ingredients. The open front may be opened and closed by a door 20 hinge-coupled with the body 10 to be pivotable up and down. The door 20 may include a handle 21.

On a top end of the body 10, a cooktop portion 13 on which a container in which ingredients are contained is disposed to be heated, a display portion 11 that displays various pieces of operation information of the gas oven 1, and an operation portion 12 for operating an operation of the gas oven 1.

Meanwhile, a plurality of supporters 36 on which a rack (not shown) to put ingredients thereon is mountable are provided inside the cooking space 40. The plurality of supporters 36 may be provided to protrude from the left sidewall 33 and the right sidewall 34.

A divider 43 capable of dividing the cooking space 40 may be separably mounted on the plurality of supporters 36. The divider 43 may be horizontally mounted in the cooking space 40 to divide the cooking space 40 into an upper separate cooking space 41 and a lower separate cooking space 42.

Hereinafter, the upper separate cooking space 41 will be referred to as a first separate cooking space 41, and the lower separate cooking space 42 will be referred to as a second separate cooking space 42. Respective sizes of the first separate cooking space 41 and the second separate cooking space 42 are not necessarily identical to each other and may be different from each other. The divider 43 may have an insulating material, and may insulate the first separate cooking space 41 and the second separate cooking space 42 from each other.

One of the plurality of burners 61 is provided in the first separate cooking space 41, and another burner (not shown) of the plurality of burners 61 is provided in the second separate cooking space 42. Hereinafter, the burner 61 provided in the first separate cooking space 41 will be referred to as a first burner 61 and the burner provided in the second separate cooking space 42 will be referred to as a second burner (not shown). Accordingly, the first burner 61 may emit heat to the first separate cooking space 41 and the second burner may emit heat to the second separate cooking space 42. The second burner is disposed below a second air supply flow channel 70, that is, below the bottom wall 32 to discharge heated air through the second air supply flow channel 70.

Also, one convection fan 51 of the plurality of convection fans 51 and 52 is provided in the first separate cooking space 41 and the other convection fan 52 of the plurality of convection fans 51 and 52 is provided in the second separate cooking space 42. Accordingly, the convection fan 51 may convect air in the first separate cooking space 41 and the convection fan 52 may convect air in the second separate cooking space 42.

A storage compartment 90 capable of storing cooking containers may be provided below the cooking space 40. The storage compartment 90 may be opened and closed by a drawer 91 slidably inserted and withdrawn. The drawer 91 may include a handle 92.

Meanwhile, the gas oven 1 may include the second air supply flow channel 70 that connects the second separate cooking space 42 with an outside of the body 10 to supply air to the second separate cooking space 42. As is well known, gas, air, and flames are necessary for combustion, and the air for combustion may be supplied to the second separate cooking space 42 through the second air supply flow channel 70.

The second air supply flow channel 70 may supply air to the second separate cooking space 42 when the divider 43 is mounted in the cooking space 40 and may supply air to the entire cooking space 40 when the divider 43 is removed from the cooking space 40.

Also, the gas oven 1 may include a main air discharge flow channel (not shown) that connects the first separate cooking space 41 with the outside of the body 10 to discharge waste gas of the first separate cooking space 41. Here, the waste gas means combustion gas that occurs after combustion. When gas is completely burned, carbon monoxide, steam, etc. may occur. When gas is incompletely burned, carbon monoxide, hydrogen, sulfur, etc. may occur. When the waste gas is not discharged and remains, since incomplete combustion occurs at a burner, it is necessary to discharge the waste gas outward.

The main air discharge flow channel may be formed of an air discharge hole that passes through the top wall 31 and an air discharge duct that connects the air discharge hole with the outside of the body 10.

The main air discharge flow channel may discharge the waste gas in the first separate cooking space 41 when the divider 43 is mounted in the cooking space 40, and may discharge the waste gas in the entire cooking space 40 when the divider 43 is removed from the cooking space 40.

Also, the gas oven 1 includes an air supply device 100 that may naturally or forcibly supply air to the first separate cooking space 41. Basically, the air supply device 100 is intended to supply air to the first separate cooking space 41 when the divider 43 is mounted in the cooking space 40.

This is because air supplied to the second separate cooking space 42 through the second air supply flow channel 70 is prevented from flowing to the first separate cooking space 41 when the divider 43 is mounted in the cooking space 40.

In addition, the air supply device 100 supplies air to the first separate cooking space 41 when the first burner 61 and the second burner are operated together. Particularly, in this case, the air supply device 100 forcibly supplies air to the first separate cooking space 41. In this aspect, the air supply device 100 may be referred to as a forced air supply device. Detailed components and functions of the air supply device 100 will be additionally described below.

Also, the gas oven 1 includes an auxiliary air discharge device that may discharge waste gas in the second separate cooking space 42. The auxiliary air discharge device is intended to discharge the waste gas in the second separate cooking space 42 when the divider 43 is mounted in the cooking space 40.

This is because the waste gas in the second separate cooking space 42 cannot be discharged through the main air discharge flow channel when the divider 43 is mounted in the cooking space 40. The auxiliary air discharge device will be additionally described below.

Referring to FIG. 6, the air supply device 100 may include an air supply duct 114, a first air supply flow channel 110 that connects the first separate cooking space 41 with the outside of the body 10 in the air supply duct 114, and an air supply fan 120 that forces air outside the cooking space 40 to be moved to the first separate cooking space 41 through the first air supply flow channel 110.

The first air supply flow channel 110 may pass through both the rear wall 35 of the cooking space 40 and an external case 14 of the body 10. The first air supply flow channel 110 may be formed inside the air supply duct 114. A part of the air supply duct 114 may be disposed in the first separate cooking space 41. Gas and air may flow into an internal space 63 of the first burner 61 through a head portion 66 of the first burner 61. Gas may be guided to an inside of the head portion 66 through a gas supply flow channel, and may be jetted into the internal space 63 of the first burner 61 through a nozzle 76 provided at an end of the gas supply flow channel. The gas supply flow channel may be fixed to the rear wall 35 using a holder.

When gas is jetted to the internal space 63 of the first burner 61 through the nozzle 76, part of air in the air supply duct 114 may be suctioned together with gas into the internal space 63 of the first burner 61 through an inlet hole 64 formed in the head portion 66.

The gas and air that flow into the internal space 63 of the first burner 61 may be mixed in the internal space 63 of the first burner 61 and may be ejected through an ejection hole 65 (refer to FIG. 2) of the first burner 61. The mixed gas may be burned by flames ignited at an igniter (not shown). Here, the air that flows together with the gas into the first burner 61 as described above may be referred to as a primary air.

Air to be supplied to the first separate cooking space 41 through a supply guide portion 170 of a distribution unit 140 that will be described below may flow around the ejection hole 65 of the first burner 61 and be mixed with the gas ejected from the ejection hole 65 to be burned. Here, the air that does not flow into the first burner 61 and flows around the ejection hole 65 of the first burner 61 through the supply guide portion 170 may be referred to as a secondary air.

Accordingly, the first burner 61 receives the primary air and secondary air to produce combustion.

Meanwhile, the air supply fan 120 forcibly suctions air outside the cooking space 40 and allows the air to flow into the first burner 61 or around the first burner 61. As described above, the reason that the air supply fan 120 forces the air to flow is to allow the first burner 61 and the second burner to operate at the same time.

This is because waste gas, which occurs at the second burner when the first burner 61 and the second burner operate at the same time, rises and flows around the first burner 61 and then incomplete combustion occurs at the first burner 61 due to the waste gas that flows around the first burner 61 as described above. In another aspect, due to the waste gas of the second burner, it is difficult to supply the secondary air to the first burner 61.

Accordingly, to allow the first burner 61 and the second burner to operate at the same time an amount of air ejected through an overflow portion 174 among the air forcibly supplied by the air supply fan 120 must be enough to push the waste gas of the second burner to the main air discharge flow channel.

Meanwhile, air must be forcibly supplied using the air supply fan 120 not only when the divider 43 is removed from the cooking space 40, but also when the divider 43 is mounted in the cooking space 40. Since the waste gas of the second burner may flow in around the first burner 61 through a gap between the divider 43 and the door 20, a gap between the divider 43 and both of the left and right sidewalls 33 and 34 (refer to FIG. 2), and a gap between the divider 43 and the rear wall 35 even when the divider 43 is mounted in the cooking space 40.

FIG. 3 is an enlarged view of the distribution unit 140 in accordance with the first embodiment of the present disclosure. FIG. 4 is a perspective view of the distribution unit 140 in accordance with the first embodiment of the present disclosure. FIG. 5 is a perspective view illustrating a coupled state of the distribution unit 140 in accordance with the first embodiment of the present disclosure. FIG. 6 is a cross-sectional view of the air supply device 100 in accordance with the first embodiment of the present disclosure, which illustrates an air flow therein. FIG. 7 is a view illustrating an air flow in the distribution unit 140 accordance with the first embodiment of the present disclosure.

The distribution unit 140 is provided in an ejection portion 112 of the air supply flow channels 70 and 110 to distribute air supplied through the air supply flow channels 70 and 110. In detail, the distribution unit 140 is disposed in an ejection direction of the ejection portion 112 of the first air supply flow channel 110 to distribute outside air supplied through the first air supply flow channel 110 as the primary air and the secondary air. Also, the secondary air may be allowed to be efficiently supplied to the first separate cooking space 41 through the distribution unit 140.

The distribution unit 140 may be provided so as to not expose the ejection portion 112 of the air supply flow channels 70 and 110 to the cooking space 40.

That is, the distribution unit 140 may be disposed in the ejection direction of the ejection portion 112 and may be provided so as to not directly expose the ejection portion 112 to the cooking space 40. In detail, the distribution unit 140 is disposed in the ejection direction of the ejection portion 112 to cut off the air ejected from the ejection portion 112. Since the distribution unit 140 is disposed in the (air) ejection direction of the ejection portion 112, heated air formed in the cooking space 40 may be prevented from flowing back toward the ejection portion 112. In the embodiment, since the ejection portion 112 is provided in the rear wall 35, the distribution unit 140 may be disposed in front of the ejection portion 112.

Since the ejection portion 112 of the first air supply flow channel 110 for supplying outside air to the first separate cooking space 41 is disposed on the rear wall 35, the distribution unit 140 is disposed on the rear wall 35 in the embodiment. However, the distribution unit 140 is not limited thereto, and may be disposed in any one of the top wall 31, the bottom wall 32, the left sidewall 33, the right sidewall 34, and the rear wall 35 that form the inner walls of the cooking space 40 depending on a disposition of the first air supply flow channel 110.

The distribution unit 140 may be coupled with the rear wall 35 by a unit coupling portion 142. The unit coupling portion 142 may be provided above the overflow portion 174, which will be described below, and may protrude further than the overflow portion 174 to allow the overflow portion 174 to form an overflow gap 175 between the overflow portion 174 and the rear wall 35.

The distribution unit 140 may include a distribution guide portion 150 and the supply guide portion 170. The air supplied through the first air supply flow channel 110 is passed through the distribution guide portion 150 and may be discharged outside the distribution unit 140 through the supply guide portion 170. That is, the air supplied through the first air supply flow channel 110 may supply the primary air to a burner through the supply guide portion 170, or may supply the secondary air to the first separate cooking space 41. The supply guide portion 170 includes a supply portion 172 and the overflow portion 174. The supply guide portion 170 will be described below.

The distribution guide portion 150 is provided to distribute or guide the air supplied through the air supply flow channels 70 and 110. The distribution guide portion 150 may form a distribution flow channel 154 and a guide flow channel 158, which will be described below, due to an inner surface thereof. To reduce air resistance of air that flows through flow channels, the inner surface of the distribution guide portion 150 may be curved.

The distribution guide portion 150 may include a distribution portion 152 and a guide portion 156.

The distribution portion 152 may distribute the air supplied through the first air supply flow channel 110. The distribution portion 152 may be formed so as to be closer to the ejection portion 112 of the first air supply flow channel 110 than the adjacent inner surface of the distribution unit 140. In detail, in the embodiment, since the ejection portion 112 of the first air supply flow channel 110 is provided in the rear wall 35 of the cooking space 40, the distribution portion 152 may be formed closer to the ejection portion 112 of the first air supply flow channel 110 formed in the rear wall 35 than the adjacent inner surface of the distribution unit 140. In the embodiment, the distribution portion 152 may protrude further toward the rear wall 35 from the inner surface of the distribution unit 140 than an inner surface of the guide portion 156.

The distribution portion 152 may form the distribution flow channel 154 that distributes the air supplied through the ejection portion 112 of the first air supply flow channel 110. The distribution flow channel 154 may include a first distribution flow channel 154a that faces downwards and a second distribution flow channel 154b that faces upwards. The first distribution flow channel 154a may be provided to be guided by a first guide portion 156a, which will be described below, to be discharged toward a bottom of the cooking space 40. The second distribution flow channel 154b may be provided to be guided by a second guide portion 156b, which will be described below, to be discharged toward the middle and top of the cooking space 40.

The guide portion 156 is provided adjacent to the distribution portion 152 to guide the air distributed from the distribution portion 152. The guide portion 156 is provided to be connected with the distribution portion 152. The guide flow channel 158 connected with the distribution flow channel 154 is formed in the guide portion 156.

The guide portion 156 may include the first guide portion 156a and the second guide portion 156b.

The first guide portion 156a is disposed on one side of the distribution portion 152 and may be disposed closer to a bottom surface of the cooking space 40 than the distribution portion 152. The first guide portion 156a focus a first guide flow channel 158a in a longitudinal direction parallel to the bottom surface of the cooking space 40. The first guide flow channel 158a is provided to be connected with the first distribution flow channel 154a described above.

That is, air that flows through the first distribution flow channel 154a among the air distributed by the distribution portion 152 is guided to the first guide flow channel 158a.

The first guide flow channel 158a is formed in the longitudinal direction parallel to the bottom surface of the cooking space 40 to allow the secondary air to be discharged to the bottom surface of the cooking space 40. In detail, the air supplied through the first guide flow channel 158a may be discharged to the bottom surface of the cooking space 40 due to a first overflow portion 174a that will be described below. Since the distribution unit 140 is disposed in the first separate cooking space 41 in the embodiment, the air supplied through the first guide flow channel 158a and the first overflow portion 174a may be supplied to a top surface 43a of the divider 43, which forms a bottom surface of the first separate cooking space 41. Since, as will be described, the first overflow portion 174a is formed along a circumference of the first guide portion 156a, the air guided through the first guide flow channel 158a of the first guide portion 156a may be discharged not only to the bottom surface of the cooking space 40, but also to both sides of the cooking space 40.

Since the first guide flow channel 158a is formed to elongate in a longitudinal direction parallel to the top surface 43a of the divider 43 compared with the first distribution flow channel 154a, it is possible to supply the secondary air to a larger area of the top surface 43a of the divider 43 through the first guide flow channel 158a.

The second guide portion 156b is disposed on the other side of the distribution portion 152. The second guide portion 156b fauns a second guide flow channel 158b. The second guide flow channel 158b is provided to be connected with the second distribution flow channel 154b described above.

That is, air that flows through the second distribution flow channel 154b among the air distributed by the distribution portion 152 may be guided to the second guide flow channel 158b.

The second guide portion 156b is disposed above the distribution portion 152 to guide part of the air distributed by the distribution portion 152 to the supply portion 172 and a second overflow portion 174b that will be described below.

A shape of the second guide portion 156b is not limited, but may be formed as a hemispherical shape in the embodiment. In detail, the air supplied through the second guide flow channel 158b may be discharged to the top and sides of the cooking space 40 due to the second overflow portion 174b that will be described below. Since the distribution unit 140 is disposed in the first separate cooking space 41 in the embodiment, the air supplied through the second guide flow channel 158b and the second overflow portion 174b may be supplied to the top wall 31, the left sidewall 33, and the right sidewall 34 of the first separate cooking space 41. As will be described below, since the second overflow portion 174b is faulted along a circumference of the second guide portion 156b, the air guided through the second guide flow channel 158b of the second guide portion 156b may be discharged not only to the top and both sides of the cooking space 40, but also to the bottom of the cooking space 40.

The first guide portion 156a is configured to be parallel to the top surface 43a of the divider 43 in the embodiment, but is not limited thereto. Also, the guide portion 156 has been described as including a pair of such guide portions 156 for convenience of description, but is not limited thereto.
