[0002] Kitchen cooking equipment such as steam ovens and microwave ovens generally include a cavity forming a cooking cavity and a cooking component arranged in the cavity. The cavity generally includes a U-shaped frame and a front panel and an inner rear panel sealedly connected to the front and rear of the U-shaped frame. The cooking medium such as hot air / heat radiation / steam / microwaves generated by the cooking component after operation enters the cooking cavity from one side of the U-shaped frame and / or the inner rear panel to cook the food placed in the cooking cavity.

[0003] In order to ensure that the food placed in the cooking cavity is heated evenly, the cavity in the prior art generally requires that the distance between the entry surface of the cooking medium and the opposite surface (the surface opposite to the entry surface) cannot be too large, so as to avoid a significant temperature difference between the side where the entry surface is located and the side where the opposite surface is located due to the large distance.

[0097] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0098] It should be clear that the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0100] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0101] In addition, in this application, unless otherwise specified, "plurality" refers to two or more.

For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0102] Kitchen cooking equipment such as steam ovens and microwave ovens are kitchen appliances that combine steam heating, baking heating, etc., and generally include a cavity forming a cooking cavity and a cooking component arranged in the cavity. The cavity generally includes a U-shaped frame and a front panel and an inner rear panel sealedly connected to the front and rear of the U-shaped frame. The cooking medium such as hot air / heat radiation / steam / microwaves generated by the cooking component after operation enters the cooking cavity from one side of the U-shaped frame and / or the inner rear panel to cook the food placed in the cooking cavity.

[0103] In order to ensure that the food placed in the cooking cavity is heated evenly, the cavity in the prior art generally requires that the distance between the entry surface of the cooking medium and the opposite surface (the surface opposite to the entry surface) cannot be too large, so as to avoid a significant temperature difference between the side where the entry surface is located and the side where the opposite surface is located due to the large distance. However, this limits the use scenarios of kitchen cooking equipment.

[0104] To this end, the present application provides a cavity assembly and a kitchen cooking device, the structure of which can effectively improve the above-mentioned problems. Specific embodiments will be provided below to illustrate.

[0105] Example 1

[0106] like Figure 1 As shown, a kitchen cooking device according to an exemplary embodiment of the present application includes: a cavity component 1, a partition plate 2, a convection component 3, and a steam cooking component 4.

[0107] The cavity assembly 1 includes a cavity, and a cooking cavity 11 is formed in the cavity. The cooking cavity 11 is in the shape of a house with a sloping roof.

[0108] Specifically, the cooking cavity 11 includes a first surface 111 , a second surface 112 , a third surface 113 , and a fourth surface 114 .

[0109] The first surface 111 is a bottom surface.

[0110] The second surface 112 is disposed opposite to the first surface 111 . Specifically, the second surface 112 is a top surface disposed opposite to the bottom surface. The second surface 112 includes a first cooking surface 1121 and a second cooking surface 1122 .

[0111] The third surface 113 is the left side surface, and the third surface 113 is connected to the first cooking surface 1121. Specifically, the top of the third surface 113 is connected to the left portion of the first cooking surface 1121, and the bottom of the third surface 113 is connected to the left portion of the first surface 111.

[0112] Fourth side 114 is the right side and is disposed opposite third side 113. Fourth side 114 is connected to second cooking surface 1122. Specifically, the top of fourth side 114 is connected to the right portion of second cooking surface 1122, and the bottom of fourth side 114 is connected to the right portion of first side 111. It should be understood that in other embodiments, the positions of the first through fourth sides can be interchanged. For example, first side 111 can be the bottom side, second side 112 can be the top side, third side 113 can be the front side, and fourth side 114 can be the rear side.

[0113] The first and second cooking surfaces define an angle A between them, where 0°<A<180°. For example, the first and second cooking surfaces are planar, and the angle A between them is 140°. Of course, in other embodiments, the first and second cooking surfaces may also be curved, and the angle A may be other degrees.

[0114] The cooking medium can enter the cooking cavity 11 from the first cooking surface 1121 and / or the second cooking surface 1122. Specifically, the angle A is 140°. This prevents a too small angle A from causing a sharp shape in the second surface 112 of the entire cooking cavity 11 and preventing the two streams of cooking medium from colliding when entering the cooking cavity 11, thereby wasting energy. It also prevents a too large angle A from preventing the cooking medium from entering the cooking cavity parallel to the first cooking surface 1121 and the second cooking surface 1122, thereby causing uneven heating of the food.

[0115] The cooking medium may be hot air, microwaves, or thermal radiation. For example, the first cooking surface 1121 and / or the second cooking surface 1122 may be provided with holes, through which hot air enters the cooking cavity 11, thereby heating the food. Of course, in other embodiments, the first cooking surface 1121 and / or the second cooking surface 1122 may also be provided with microwave inlets or thermal radiation heating elements, thereby allowing microwaves or thermal radiation, serving as the cooking medium, to enter the cooking cavity 11. It should be understood that in other embodiments, the cooking mediums entering the cooking cavity 11 through the first cooking surface 1121 and the second cooking surface 1122 may be different cooking media, and multiple cooking media may pass through the first cooking surface 1121 and the second cooking surface 1122. For example, microwaves and hot air may enter the cooking cavity 11 through the first cooking surface 1121, while thermal radiation and hot air may enter the cooking cavity 11 through the second cooking surface 1122.

[0116] The kitchen cooking device can also control whether the cooking medium can enter the cooking cavity through the first cooking surface 1121 and the second cooking surface 1122, enabling multiple cooking modes for more evenly heated food. For example, the cooking medium can only enter the cooking cavity 11 through the first cooking surface 1121, only through the second cooking surface 1122, or only through both the first and second cooking surfaces 1121, 1122. If the left side of the food is overheated, the cooking medium can be prevented from entering the cooking cavity 11 through the first cooking surface 1121; if the right side of the food is overheated, the cooking medium can be prevented from entering the cooking cavity 11 through the second cooking surface 1122, thereby achieving even heating of the food. These multiple cooking modes can be achieved by turning on or off the motors, microwave emitting devices, or heat radiant heating elements of the first and second cooking surfaces 1121, 1122.

[0117] In this embodiment, by defining an angle A between the first and second cooking surfaces, the second surface 112 is shaped to surround the food. This shortens the overall distance between each portion of the food and the second surface 112, allowing the cooking medium to heat the food more evenly when entering the cooking cavity 11. Furthermore, since the cooking medium can enter the cooking cavity from either the first or second cooking surface, the cooking medium can enter the cooking cavity 11 from either the first or second cooking surface depending on the food being heated. This allows for diverse heating modes, meets cooking needs, and ensures even heating of the food.

[0118] Preferably, the cooking cavity 11 further comprises a front side and a rear side (not shown) arranged opposite to the front side. A cavity opening 115 is provided on the front side, through which food can be placed in or taken out of the cooking cavity 11.

[0119] Preferably, in this embodiment, first openings 11211 are provided on the first cooking surface 1121 and the second cooking surface 1122. Hot air can enter the cooking cavity 11 through the first openings 11211, thereby heating the food. Of course, in other embodiments, depending on the type of food being heated, the first cooking surface 1121 may be provided with a first opening 11211 for hot air to enter through the first opening 11211, while the second cooking surface 1122 may be provided with a microwave inlet or a heat radiation heating element for microwaves or heat radiation to enter through the second cooking surface.

[0120] The partition plate 2 is removably mounted within the cooking cavity 11. The partition plate 2 can be sealed against the inner wall of the cooking cavity 11 to divide the cooking cavity 11 into two independent upper and lower cooking cavities. Specifically, the partition plate 2 is placed on the third surface 113 and the fourth surface 114. For example, the inner sides of the third surface 113 and the fourth surface 114 have ridges, and the partition plate 2 can be placed on the ridges. For example, the periphery of the partition plate 2 is a rubber strip. When placed on the ridges, the rubber strip around the partition plate 2 can seal the inner wall of the cooking cavity 11, thereby dividing the cooking cavity 11 into two independent upper and lower cooking cavities. The user can choose to place or remove the partition plate 2 according to the type of food to be heated or the heating mode. When the partition plate 2 is removed, the kitchen cooking device can heat the food in the entire cooking cavity 11; when the partition plate 2 is added, the first and second cooking surfaces can heat the food in the upper cooking cavity separately. At the same time, because the food is closer to the first and second cooking surfaces, the food is heated more evenly. When the lower cooking cavity is also provided with a corresponding heating component, the food in the lower cooking cavity can also be heated, so that the kitchen cooking device can heat the upper and lower cooking cavities, the heating modes are more diverse, the food heating effect is better, and the efficiency is higher.

[0121] The convection component 3 cooperates with the first cooking surface 1121 or the second cooking surface 1122 to form airflow in the cooking cavity 11. In this embodiment, the first cooking surface 1121 and the second cooking surface 1122 are each equipped with a convection component 3.

[0122] Specifically, the convection assembly 3 includes a motor shaft 31, a motor 32 connected to one end of the motor shaft 31, and fan blades 33 connected to the other end of the motor shaft 31. The fan blades 33 are located within the air duct. To ensure airflow, the first opening 11211 includes an air inlet 112111 and an air outlet 112112. The cooking cavity 11 also includes an air duct mounted on the upper surface of the second surface 112. The air duct is a hood covering the first opening 11211. Airflow can flow between the air duct and the cooking cavity 11 through the air inlet 112111 and the air outlet 112112. In this embodiment, the air outlet 112112 is located on both sides of the air inlet 112111. In other embodiments, multiple air outlets 112112 can be evenly distributed around the air inlet 112111 to achieve a more uniform heating effect.

[0123] The motor 32 rotates the fan blades 33, causing the gas within the cooking chamber 11 to enter the air duct through the air inlet 112111 of the first cooking surface 1121 or the second cooking surface 1122, and then return to the cooking chamber 11 through the air outlet 112112 of the first cooking surface 1121 or the second cooking surface 1122, thereby forming a first airflow. For example, the fan blades 33 are centrifugal blades, which can radially push gas at the fan axis away from the centrifugal blades. The air inlet 112111 is located below the fan blade 33 axis, and the air outlet 112112 is located on either side of the fan blade 33. When the fan blades 33 rotate, the gas within the cooking chamber 11 is drawn into the air duct through the air inlet 112111. Simultaneously, the fan blades 33 push the gas away, and the gas within the air duct returns to the cooking chamber 11 through the air outlet 112112.

[0124] Preferably, the convection assembly 3 further includes a heating element 34 disposed in the air duct and close to the fan blades 33. Specifically, the heating element 34 is a heating tube, which is installed between the fan blades 33 and the air inlet holes 112111 and can heat the moving air, turning the first airflow into a hot airflow, thereby heating the food.

[0125] It should be understood that in other embodiments, the fan blades 33 may also be axial flow fan blades.

[0126] The steam cooking assembly 4 is capable of steam heating the cooking cavity 11. The steam cooking assembly 4 includes a steam generator and an air inlet duct 41, which communicates with the lower cooking cavity. Specifically, in this embodiment, the air inlet duct 41 communicates with the lower cooking cavity. When the cooking cavity 11 is removed from the partition 2, the cooking cavity 11 can be steam heated. When the partition 2 is placed in the cooking cavity 11, the lower cooking cavity can be steam heated independently. In another embodiment, the air inlet duct 41 can communicate with the upper cooking cavity alone, steam heating only the upper cooking cavity. In another embodiment, the air inlet duct 41 can communicate with both the upper and lower cooking cavities simultaneously, allowing the upper and lower cooking cavities to be steam heated independently when the partition 2 is placed in the cooking cavity 11.

[0127] Example 2

[0128] like Figure 2 FIG. 1 shows a second exemplary embodiment of a kitchen cooking device of the present application, which is substantially the same as the kitchen cooking device of Example 1. The difference between the two is that:

[0129] The third side 113 is provided with a second opening 1131, and the fourth side 114 is provided with a second opening 1141. Specifically, second openings 1131 and 1141 are positioned below the partition plate 4. In this case, the heated airflow can enter the cooking cavity 11 through the second openings 1131 and 1141, thereby heating the bottom of the food and heating the food more evenly. When the partition plate 4 is removed, the airflow entering the cooking cavity 11 through the second openings 1131 and 1141 can heat the food simultaneously with the airflow entering the cooking cavity 11 through the first opening 11211, heating the food more evenly. When the partition plate 4 is placed, the cooking medium passing through the first opening 11211 can heat the food in the upper cooking cavity, while the cooking medium passing through the second openings 1131 and 1141 and the steam provided by the steam cooking assembly 4 can heat the food in the lower cooking cavity, providing the user with more heating modes to choose from.

[0130] It should be understood that in other embodiments, the second openings 1131 and 1141 may also be provided above the partition plate or simultaneously provided above and below the partition plate.

[0131] Example 3

[0132] like Figure 3 As shown, the kitchen cooking device of the third exemplary embodiment of the present application includes: a cavity component 1, a partition plate 2, a convection component 3, a steam cooking component 4, and an opening control switch 5.

[0133] The cavity assembly 1 includes a cavity, in which a cooking cavity 11 is formed. The cavity assembly 1 also includes a first flow guide 12 and a second flow guide 13.

Second side 112 is the top side disposed opposite the bottom side. Second side 112 includes a first cooking surface 1121 and a second cooking surface 1122. Third side 113 is the left side and is connected to first cooking surface 1121. Fourth side 114 is the right side and is connected to second cooking surface 1122. Third and fourth sides 113 and 114 are disposed opposite each other.

[0135] There is an angle A between the first and second cooking surfaces, and 0°<A<180°. Specifically, the angle A is 140°.

[0136] Cooking medium can enter the cooking cavity 11 from the first cooking surface 1121 and / or the second cooking surface 1122 .

[0137] Preferably, the cooking cavity 11 further comprises a front side and a rear side opposite to the front side. A cavity opening 115 is provided on the front side.

[0138] Preferably, a first opening 11211 is provided on the first cooking surface 1121 and the second cooking surface 1122. Hot air can enter the cooking cavity 11 through the first opening 11211, thereby heating food.

[0139] Preferably, the third surface 113 is provided with a second opening 1131 , and the fourth surface 114 is provided with a second opening 1141 . The second openings 1131 and 1141 are provided below the partition plate 4 .

[0140] Specifically, the first air guide 12 is disposed on one side of the cavity and includes a first air duct 121. One end of the first air duct 121 connects to a first opening 11211 on the first cooking surface 1121, and the other end connects to a second opening 1131 on the third surface 113. Specifically, the first air guide 12 is disposed on the left side of the cavity, with a portion mounted on the first cooking surface 1121 and a portion mounted on the third surface 113. The first air duct 121 is an L-shaped cover plate that covers the first opening 11211 and the second opening 1131, allowing airflow within the cooking cavity 11 and within the first air guide 12 to interchange through the first opening 11211 and the second opening 1131. Similarly, the second air guide 13 is disposed on the right side of the cavity and includes a second air duct 131. It should be understood that in other embodiments, only one of the first and second air guides may be provided, and the first and second air guides may also have other shapes.

[0141] The partition plate 2 is removably mounted within the cooking cavity 11. The partition plate 2 is hermetically connected to the inner wall of the cooking cavity 11 to divide the cooking cavity 11 into two independent upper and lower cooking cavities. Specifically, the partition plate 2 is positioned on the third side 113 and the fourth side 114.

[0142] The convection assembly 3 cooperates with the first cooking surface 1121 or the second cooking surface 1122 to generate airflow within the cooking cavity. The convection assembly 3 includes a motor shaft 31, a motor 32 connected to one end of the motor shaft 31, and fan blades 33 connected to the other end of the motor shaft 31. The fan blades 33 are positioned within the air duct. Specifically, in this embodiment, the motor 32 rotates the fan blades 33, causing the gas within the cooking cavity 11 to enter the first air duct 121 through the second openings 1131 and 1141 of the third and fourth surfaces, and then return to the cooking cavity 11 through the first opening 11211 of the first cooking surface 1121 or the second cooking surface 1122, thereby generating airflow.

[0143] For example, the fan blades 33 are axial flow fan blades, which can push air away from the fan blades in the axial direction. The first opening 11211 is located below the fan blades 33. When the fan blades 33 rotate, the air in the first air duct 121 returns to the cooking cavity 11 through the first opening 11211, and the air in the cooking cavity 11 is replenished into the air duct through the second opening 1131, thus forming an air circulation.

[0144] It should be understood that in other embodiments, the first cooking surface 1121 and the second cooking surface 1122 may further include air inlets, allowing the gas within the cooking cavity 11 to re-enter the first air duct 121 and the second air duct 131 through the air inlets, thereby creating air circulation. When the partition plate 2 is removed, the gas within the first air duct 121 and the second air duct 131 enters the cooking cavity 11 through the first opening 11211 to heat the food. Simultaneously, the airflow within the cooking cavity 11 returns to the first air duct 121 through the second openings 1131 and 1141 and the air inlets, thereby creating air circulation and heating the food. When the partition plate 2 is placed, the gas within the first air duct 121 enters the upper cooking cavity through the first opening 11211 to heat the food. Simultaneously, the airflow within the upper cooking cavity returns to the first air duct 121 through the air inlet, thereby creating air circulation and heating the food. In this case, the gas within the lower cooking cavity does not participate in the circulation.

[0145] Preferably, the convection assembly 3 further includes a heating element 34 disposed in the air duct and close to the fan blades 33. Specifically, the heating element 34 is a heating tube installed between the fan blades 33 and the first opening 11211, which can heat the moving gas, turning the airflow into hot airflow, thereby heating the food.

[0146] Preferably, the air duct is provided with a secondary heating element 35 near the second openings 1131 and 1141. Specifically, the first air duct 121 and the second air duct 131 are both provided with a secondary heating element 35, and the secondary heating element 35 is a heating tube.

[0147] The steam cooking assembly 4 is capable of steam heating the cooking cavity 11. It includes a steam generator and an air inlet pipe 41, which communicates with the lower cooking cavity. Specifically, in this embodiment, the air inlet pipe 41 communicates with the lower cooking cavity. When the cooking cavity 11 is removed from the partition plate 2, the cooking cavity 11 can be steam heated. When the partition plate 2 is placed in the cooking cavity 11, the lower cooking cavity can be steam heated independently.

[0148] The opening control switch 5 can be used to adjust the opening of the air duct for flow. Specifically, the opening control switch 5 is located at the bend between the L-shaped first air duct 121 and the second air duct 131. The opening control switch 5 includes a motor, a motor shaft, and a baffle. When the motor rotates, the motor shaft drives the baffle to rotate, thereby adjusting the opening of the air duct for flow.

[0149] Example 4:

[0150] like Figure 4-6 As shown, the kitchen cooking device of the fourth exemplary embodiment of the present application includes: a cavity component 1, a partition plate 2, a convection component 3, a steam cooking component 4, and an opening control switch 5.

[0151] The cavity assembly 1 includes a cavity, in which a cooking cavity 11 is formed. The cooking cavity 11 is in the shape of a house with a sloping roof. The cavity assembly 1 also includes a first flow guide 12 and a second flow guide 13.

[0152] Specifically, cooking cavity 11 includes a first side 111, a second side 112, a third side 113, and a fourth side 114. First side 111 is the bottom side. Second side 112 is disposed opposite first side 111. Specifically, second side 112 is the top side disposed opposite the bottom side. Second side 112 includes a first cooking surface 1121 and a second cooking surface 1122. Third side 113 is the left side and is connected to first cooking surface 1121. Fourth side 114 is the right side and is connected to second cooking surface 1122. Third side 113 and fourth side 114 are disposed opposite each other.

[0153] The first and second cooking surfaces have an angle A therebetween, and 0°<A<180°. For example, the first and second cooking surfaces are planes, and the angle A therebetween is 140°.

[0154] Preferably, the cooking cavity 11 further comprises a front side and a rear side (not shown) arranged opposite to the front side. A cavity opening 115 is provided on the front side, through which food can be placed in or taken out of the cooking cavity 11.

[0155] Preferably, a first opening 11211 is provided on the first cooking surface 1121 and / or the second cooking surface 1122. Airflow can enter the cooking cavity 11 through the first opening 11211, thereby heating food. The first opening 11211 includes an air inlet 112111 and an air outlet 112112.

[0156] Preferably, the third surface 113 is provided with a second opening 1131 , and the fourth surface 114 is provided with a second opening 1141 . The second openings 1131 and 1141 are provided below the partition plate 4 .

[0157] The first air guide 12 is located on one side of the cavity and includes a first air duct 121. One end of the first air duct 121 is connected to the first opening 11211 on the first cooking surface 1121, and the other end is connected to the second opening 1131 on the third surface 113. Specifically, the first air guide 12 is located on the left side of the cavity. The first air duct 121 is an L-shaped cover that covers the first opening 11211 and the second opening 1131. Similarly, the second air guide 13 is located on the right side of the cavity and includes a second air duct 131.

[0158] Gas in the cooking chamber 11 enters the air duct through the air inlet 112111 and then returns to the cooking chamber 11 through the air outlet 112112, forming a first airflow. Gas in the cooking chamber 11 enters the air duct through the air inlet 112111 and then returns to the cooking chamber 11 through the second opening 1131, forming a second airflow. Specifically, gas in the cooking chamber 11 enters the first air duct 121 through the air inlet 112111 of the first cooking surface 1121. A portion of the gas in the first air duct 121 can return to the cooking chamber through the air outlet 112112, forming the first airflow. A portion of the gas in the first air duct 121 can continue flowing along the first air duct 121 and return to the cooking chamber through the second opening 1131, forming the second airflow. The first and second airflows heat the food together, resulting in more even heating and enabling the cooking device to operate in multiple heating modes. Similarly, airflow passing through the second cooking surface 1122 can also form the first and second airflows. In this embodiment, the first airflow, due to its short travel distance, can achieve an air frying heating mode; the second airflow, due to its longer travel distance, can achieve a forced convection circulation heating mode. In this embodiment, the presence or absence of the second airflow can also be controlled by controlling the opening of the air duct. For example, the cooking chamber 11 may contain only the first airflow, or both the first and second airflows.

[0159] The partition plate 2 is detachably mounted in the cooking cavity 11. The partition plate 2 can be sealedly connected to the inner wall of the cooking cavity 11 to divide the cooking cavity 11 into two independent upper and lower cooking cavities.

[0160] The convection assembly 3 cooperates with the first cooking surface 1121 or the second cooking surface 1122 to form a first airflow or a second airflow within the cooking cavity. The convection assembly 3 includes a motor shaft 31, a motor 32 connected to one end of the motor shaft 31, and a fan blade 33 connected to the other end of the motor shaft 31. The fan blade 33 is located within the air duct. Specifically, the fan blade 33 is a centrifugal fan blade. When the fan blade 33 rotates, the gas within the cooking cavity 11 is drawn into the air duct through the air inlet 112111. Simultaneously, the fan blade 33 pushes away the gas, and some of the gas within the air duct re-enters the cooking cavity 11 through the air outlet 112112, forming a first airflow. Some of the gas within the air duct continues to flow along the first air duct 121, passing through the second opening 1131 and returning to the cooking cavity, forming a second airflow.

[0161] Preferably, the convection assembly 3 further includes a heating element 34 disposed in the air duct and close to the fan blades 33. Specifically, the heating element 34 is a heating tube, which is installed between the fan blades 33 and the air inlet holes 112111 and can heat the moving air, turning the first airflow into a hot airflow, thereby heating the food.

[0162] Preferably, the air duct is provided with a secondary heating element 35 near the second openings 1131 and 1141. Specifically, the first air duct 121 and the second air duct 131 are both provided with a secondary heating element 35 ( Figure 4 The secondary heating element 35 in the second air duct 131 is omitted, and the secondary heating element 35 is a heating tube, which can heat the second airflow.

[0163] When the partition plate 2 is removed, the first airflow and the second airflow heat the food together. When the partition plate 2 is placed, the first airflow can heat the food in the upper cooking cavity, and the second airflow can heat the food in the lower cooking cavity.

[0164] The steam cooking assembly 4 is capable of steam heating the cooking cavity 11. It includes a steam generator and an air inlet pipe 41, which communicates with the lower cooking cavity. Specifically, in this embodiment, the air inlet pipe 41 communicates with the lower cooking cavity. When the cooking cavity 11 is removed from the partition plate 2, the cooking cavity 11 can be steam heated. When the partition plate 2 is placed in the cooking cavity 11, the lower cooking cavity can be steam heated independently.

[0165] Among them, the opening control switch 5 can be used to adjust the opening size of the air duct flow. Specifically, the opening control switch 5 is set at the bend of the L-shaped first air duct 121 and the second air duct 131. The opening control switch 5 includes a motor, a motor shaft, and a baffle. When the motor rotates, the motor shaft drives the baffle to rotate, thereby adjusting the opening size of the air duct flow. When the opening is zero, there is no airflow flowing through the second openings 1131 and 1141 in the air duct, and thus the second airflow cannot be formed. When the temperature of the top of the food is too high, the opening control switch 5 controls the opening to open, forming a second airflow, so that the temperature of the heated top of the food drops; when the bottom of the food is heated unevenly, the opening control switch 5 can increase the opening to increase the flow rate of the second airflow, so that the bottom of the food is heated evenly.

[0166] Preferably, the cooking device can also be provided with temperature sensors, which are arranged in the upper cooking cavity and the lower cooking cavity to detect the temperature of the upper cooking cavity and the lower cooking cavity. The opening control switch 5 can control the opening size of the air duct flow according to the parameters of the temperature sensor, thereby further improving the heating effect.

Specifically, air can enter the cooking cavity through the first opening 11211 on the first cooking surface 1121, heating the top of the food. Air can then enter the second air duct 131 through the second opening 1141, and then re-enter the cooking cavity through the first opening 11211 on the second cooking surface 1122, creating an air circulation system. This allows air to circulate around the food, evenly heating it.
