Shell structure and cooking apparatus

Abstract

The application provides a shell structure and a cooking device. The shell structure comprises an inner shell, an outer shell and a heat insulation member. The inner shell is provided with a cooking cavity for cooking food. The outer shell surrounds the inner shell and forms an air passage between the inner shell and the outer shell. The outer shell is provided with an air inlet and an air outlet which are connected to the air passage. Air enters the air passage through the air inlet and then is discharged through the air outlet. During cooking, heat is transferred from the inner shell to the air passage. When air flows through the air passage, the air can take away part of the heat. Finally, the heat is taken away from the air outlet. The heat insulation member is connected to the inner shell and can block the transfer of part of the heat from the inner shell to the outer shell. Through the heat dissipation of the air passage and the heat insulation effect of the heat insulation member, the heat transferred to the outer shell can be significantly reduced, thereby reducing the surface temperature of the cooking device and eliminating the safety hazards caused by the high surface temperature of the cooking device.

Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a housing structure and cooking equipment. Background Technology

[0002] Due to the high strength, easy cleaning, durability, lack of odor, and non-toxicity of stainless steel, the shells of most current cooking equipment are made of stainless steel.

[0003] Taking a stainless steel air fryer as an example, the air fryer is equipped with a cooking chamber and a heating module. When working, the air fryer heats the food in the cooking chamber by the hot air generated by the internal heating module, thereby achieving the cooking effect.

[0004] Because stainless steel has good thermal conductivity, the heat from the internal hot air can easily be directed to the outer shell of the air fryer during operation, causing the surface temperature of the air fryer to become too high, which poses a certain safety hazard. Utility Model Content

[0005] This application provides a shell structure and cooking equipment. The shell structure prevents heat from being transferred to the surface of the shell structure by forming a ventilation interlayer inside for heat dissipation and by providing heat insulation of the insulation component set in the ventilation interlayer. This solves the technical problem that the surface temperature of the shell of a stainless steel air fryer is too high, which poses certain safety hazards.

[0006] On one hand, this application provides a shell structure, including:

[0007] The inner shell is equipped with a cooking cavity;

[0008] The outer shell surrounds the inner shell and forms a ventilation channel between them. The outer shell is provided with an air inlet and an air outlet, and the air inlet and the air outlet are connected to the ventilation channel.

[0009] A heat insulation element is located in the ventilation channel and connected to the inner shell.

[0010] In some embodiments, the inner shell includes a cavity enclosure, a reflector, and a mounting cover. The reflector is fixed to the top side of the cavity enclosure and together with the cavity enclosure forms the cooking cavity. The mounting cover is connected to the reflector for mounting a heating assembly. The heat insulation member encloses at least a portion of the mounting cover.

[0011] In some embodiments, the side of the oven cavity enclosure is provided with an insertion port for inserting a cooking bucket, the insertion port communicating with the cooking cavity, and the heat insulation member is at least partially disposed on the side of the reflector near the insertion port.

[0012] In some embodiments, the heat insulation component includes a heat insulation portion and a connecting portion, the heat insulation portion being fitted to the side of the mounting cover near the insertion port, and the connecting portion being disposed on the heat insulation portion for connecting the cooking pot.

[0013] In some embodiments, the reflector has an extension on its periphery, the extension extending to the ventilation channel and connecting to the housing, the extension dividing the ventilation channel into an air inlet section and an air outlet section, the air inlet section surrounding the cooking cavity, the air outlet section surrounding the mounting cover, the extension having a plurality of spaced-apart connecting holes, each connecting hole connecting the air inlet section and the air outlet section, the air inlet and the air outlet respectively connecting the air inlet section and the air outlet section.

[0014] In some embodiments, the edge of the extension is bent toward the cooking cavity and forms a flange, the flange being connected to the outer casing.

[0015] In some embodiments, the housing includes a base, a bottom enclosure, and a top enclosure. The base is connected to the bottom side of the furnace cavity enclosure. The bottom enclosure surrounds the furnace cavity enclosure and forms the air inlet section between the bottom enclosure and the furnace cavity enclosure. The upper and lower sides of the bottom enclosure are respectively connected to the base and the extension. The top enclosure is connected to and surrounds the mounting cover and forms the air outlet section between the top enclosure and the mounting cover.

[0016] In some embodiments, the top enclosure includes an arcuate guide portion and an enclosure portion, one side of the arcuate guide portion being connected to the extension portion, the other side of the arcuate guide portion being bent toward the mounting cover, and the enclosure portion being connected to the side of the arcuate guide portion near the mounting cover.

[0017] In some embodiments, the housing structure further includes a heating support member, one side of which is connected to and surrounds the mounting cover, and the other side of which extends toward the housing.

[0018] On the other hand, this application provides a cooking device, including:

[0019] Shell structure;

[0020] A cooking bucket, installed in the cooking cavity of the aforementioned shell structure;

[0021] A heating component, installed in the inner shell of the aforementioned shell structure, is used to supply heat to the cooking pot.

[0022] The shell structure provided in this application comprises an inner shell, an outer shell, and a heat insulation component. The inner shell has a cooking cavity for cooking food. The outer shell surrounds the inner shell, forming a ventilation channel between them. The outer shell has an air inlet and an air outlet connecting to the ventilation channel. Air enters the ventilation channel through the air inlet and exits through the air outlet. During cooking, heat is transferred from the inner shell to the ventilation channel. As air flows through the ventilation channel, it carries away some of the heat, ultimately expelling it through the air outlet. The heat insulation component, connected to the inner shell, prevents some heat from being transferred from the inner shell to the outer shell. Through the heat dissipation of the ventilation channel and the heat insulation effect of the heat insulation component, the heat transferred to the outer shell is significantly reduced, thereby lowering the surface temperature of the cooking equipment and eliminating safety hazards caused by excessively high surface temperatures.

[0037] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] Based on the characteristics of stainless steel, such as high strength, easy cleaning, durability, non-odor generation, and non-toxicity, the outer shell of most cooking equipment is currently made of stainless steel and other metal materials. Taking air fryers made of stainless steel and other metal materials as an example, because stainless steel has good thermal conductivity, the internal heat of cooking equipment such as air fryers is easily conducted to the stainless steel outer shell during operation, causing the outer shell temperature to rise, which poses certain safety hazards.

[0040] To address the technical problem of excessively high surface temperature in stainless steel air fryers, which poses a safety hazard, this application provides a shell structure. The shell structure 50 prevents heat transfer to the surface of the shell structure 50 by forming a ventilation interlayer for heat dissipation and by using a heat insulation component 30 disposed in the ventilation interlayer for heat insulation. The heat insulation component 30 disposed in the heat dissipation interlayer also prevents a large amount of heat from being transferred to the shell surface, thus solving the problem of overheating of the air fryer surface.

[0041] It should be noted that the shell structure 50 described in this application is used in, but not limited to, air fryers, and can also be applied to cooking equipment that uses high temperature for cooking, such as ovens and steam-roast-fryer combos. For ease of explanation, this application only uses the application of the shell structure 50 in an air fryer as an example. The principle of the shell structure 50 in other cooking equipment is essentially the same as that in an air fryer, and will not be described in detail here.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] To better understand this application, the following is combined with... Figures 1 to 6 The technical solution of this application is described in detail below:

[0044] The shell structure provided in the embodiments of this application, such as Figure 1 and Figure 2 As shown, the device includes an inner shell 10, an outer shell 20, and a heat insulation component 30. The inner shell 10 is provided with a cooking cavity 11. The outer shell 20 surrounds the inner shell 10 and forms a ventilation channel 10a between the outer shell 20 and the inner shell 10. The outer shell 20 is provided with an air inlet 21 and an air outlet 22, which are connected to the ventilation channel 10a. The heat insulation component 30 is located in the ventilation channel 10a and connected to the inner shell 10.

[0045] Specifically, the shell structure 50 is provided with an inner shell 10, an outer shell 20 and a heat insulation component 30. The inner shell 10 is provided with a cooking cavity 11. The inner shell 10 can be provided with a heating component to supply heat to the cooking cavity 11. Under the heat supply of the heating component, the cooking cavity 11 can cook the food inside. The outer shell 20 surrounds the inner shell 10 and forms a ventilation channel 10a between the outer shell 20 and the inner shell 10. The outer shell 20 is provided with an air inlet 21 and an air outlet 22 that connect to the ventilation channel 10a. Air can enter the ventilation channel 10a through the air inlet 21 and then exit through the air outlet 22.

[0046] After assembling the heating components in the inner shell 10, the shell structure 50 can form a corresponding cooking device. For example, when the heating components are configured as heating tubes, fans, etc., an air fryer structure can be formed; when the heating components are configured as upper and lower dual heating tubes, centrifugal fans, etc., an oven structure can be formed; and when the heating components are configured as heating tubes, fans, and a steam generator located in the cooking cavity 11, a steam oven structure can be formed.

[0047] During the cooking process of the food in the cooking chamber 11, the heat from the heating element and the cooking chamber 11 is transferred from the inner shell 10 to the ventilation channel 10a. When the air flows through the ventilation channel 10a, it can carry away some of the heat. After the air is released through the air outlet 22, it can carry away some of the heat, thus blocking the transfer of heat to the outer shell 20 through heat dissipation. The heat insulation component 30 is connected to the inner shell 10 and can block some of the heat from the inner shell 10 to the outer shell 20. Therefore, with the ventilation and heat dissipation of the ventilation channel 10a and the heat insulation of the heat insulation component 30, the heat transferred to the outer shell 20 can be significantly reduced, thereby reducing the surface temperature of the air fryer and other cooking equipment and eliminating the safety hazards caused by the air fryer being too hot.

[0048] In this embodiment, the inner shell 10 primarily serves to support the heating components and cooking ingredients. It can be made of any non-toxic and harmless material capable of withstanding and maintaining high temperatures during operation. For example, the inner shell 10 can be made of metal materials such as stainless steel, aluminum alloy, and carbon steel, or plastic materials such as PEEK (polyetheretherketone) and PES (polyethersulfone). This embodiment does not impose specific limitations.

[0049] Understandably, the volume and shape of the inner shell 10 can be adapted to actual needs. The cooking cavity 11 of the inner shell 10 can be a single cavity, a double cavity, or a multi-cavity structure with more than two cavities. The cooking cavity 11 is mainly used to accommodate the cooking bucket 60 filled with ingredients. When the cooking cavity 11 of the inner shell 10 is a multi-cavity structure with more than two cavities, only the corresponding number of cooking buckets 60 need to be set.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the inner shell 10 includes a cavity enclosure 12, a reflector 14, and a mounting cover 15. The reflector 14 is fixed to the top side of the cavity enclosure 12 and together with the cavity enclosure 12 forms a cooking cavity 11. The mounting cover 15 is connected to the reflector 14 and is used to install heating components. The heat insulation member 30 encloses at least part of the mounting cover 15. Specifically, the reflector 14 is installed on the top side of the cavity enclosure 12. By enclosing the cavity enclosure 12, the cooking cavity 11 structure is formed. When high-temperature hot air enters the cooking cavity 11, the heat can be "locked" in the cooking cavity 11 by the reflection of the cavity enclosure 12 and the reflector 14. The mounting cover 15 is installed on the reflector 14 and can be used to install heating components such as fans and heating elements that provide hot air, maintaining a constant high temperature inside the cooking cavity 11.

[0051] In this embodiment, the side of the oven cavity enclosure 12 is provided with an insertion port 13 for inserting the cooking pot 60, and the insertion port 13 communicates with the cooking cavity 11. Specifically, the insertion port 13 allows the cooking pot 60 to be inserted into the cooking cavity 11, facilitating the installation and removal of the cooking pot 60.

[0052] In this embodiment, as Figure 3 As shown, the oven cavity enclosure 12 includes an inner seat 121 and a cavity enclosure 122. The lower side of the cavity enclosure 122 is mounted on the base 23, forming a cooking cavity 11 with an opening on one side. This side opening is the insertion port 13 for the cooking pot 60 to be inserted into the cooking cavity 11. The reflector 14 is mounted on the upper side of the cavity enclosure 122.

[0053] In this embodiment, a sealing element (not shown in the figure) is provided between the mounting cover 15 and the reflector 14. The sealing element can improve the sealing performance between the mounting cover 15 and the reflector 14, prevent hot air inside the mounting cover 15 and the reflector 14 from leaking into the ventilation channel 10a through the gap between the mounting cover 15 and the reflector 14, and prevent the airflow of the ventilation channel 10a from entering the mounting cover 15 through the gap between the mounting cover 15 and the reflector 14.

[0054] In this embodiment, the area below the reflector 14 is the cooking section for cooking food, and the area above the reflector 14 is the heating section for providing hot air. This design separates the cooking section from the heating section, ensuring that cooking and heating in the air fryer do not interfere with each other. Therefore, the reflector 14 can be any structure capable of separating the cooking section from the heating section.

[0055] In some embodiments, such as Figure 2 and Figure 3As shown, the reflector 14 has an extension 141 on its periphery. The extension 141 extends to the ventilation channel 10a and connects to the outer shell 20. The extension 141 divides the ventilation channel 10a into an air inlet section 11a and an air outlet section 12a. The air inlet section 11a surrounds the cooking cavity 11, and the air outlet section 12a surrounds the mounting cover 15. The extension 141 has a number of spaced-apart connecting holes 1411. Each connecting hole 1411 connects the air inlet section 11a and the air outlet section 12a. The air inlet 21 and the air outlet 22 connect the air inlet section 11a and the air outlet section 12a, respectively. Specifically, the reflector 14 divides the ventilation channel 10a into an air inlet section 11a and an air outlet section 12a by forming an extension 141 extending toward the ventilation channel 10a. The extension 141 is provided with spaced-apart connecting holes 1411, which connect the air inlet section 11a and the air outlet section 12a. Air first enters the air inlet section 11a through the air inlet 21, then enters the air outlet section 12a through the connecting holes 1411, and finally exits from the air outlet 22. The air inlet section 11a encloses the cooking cavity 11, and the air flowing in the air inlet section 11a can carry away the heat transferred from the lower cooking part to the outer shell 20. The air outlet section 12a encloses the mounting cover 15, and the air flowing in the air outlet section 12a can carry away the heat transferred from the upper heating part to the outer shell 20. Since the structures of the air inlet section 11a and the air outlet section 12a are quite different, by setting the air inlet section 11a and the air outlet section 12a at intervals, the airflow of the air inlet section 11a and the air outlet section 12a can avoid mutual interference. Each connecting hole 1411 can smoothly guide the airflow from the air inlet section 11a to the air outlet section 12a, making the airflow in the ventilation channel 10a more orderly and enhancing the heat insulation effect.

[0056] In some embodiments, such as Figure 3 and Figure 4 As shown, the edge of the extension 141 bends toward the cooking cavity 11 to form a flange 1412, which is connected to the outer shell 20. Specifically, the flange 1412 can improve the stability of the outer shell 20 by connecting it, and can also prevent the edge of the extension 141 from scratching the assembly personnel during the assembly of the outer shell 20.

[0057] In this embodiment, the mounting cover 15 is mainly used for the installation of heating components such as fans and heating tubes. Due to the heat generated by the heating components, the surface temperature of the mounting cover 15 is relatively high.

[0058] Understandably, the outer shell 20 can be any shell structure 50 capable of enclosing the inner shell 10.

[0059] In some embodiments, such as Figure 1 and Figure 2As shown, the outer casing 20 includes a base 23, a bottom enclosure 24, and a top enclosure 25. The base 23 is connected to the bottom side of the furnace cavity enclosure 12. The bottom enclosure 24 encloses the furnace cavity enclosure 12 and forms an air inlet section 11a between them. The upper and lower sides of the bottom enclosure 24 are respectively connected to the base 23 and the extension 141. The top enclosure 25 is connected to and encloses the mounting cover 15, forming an air outlet section 12a between it and the mounting cover 15. Specifically, by enclosing the furnace cavity enclosure 12 with the bottom enclosure 24 and enclosing the mounting cover 15 with the top enclosure 25, a segmented outer casing 20 can be formed. This facilitates the assembly of the outer casing 20, improves the stability of the assembled outer casing 20, and ensures that the bottom and top insulation operations of the outer casing 20 do not interfere with each other, thus facilitating insulation.

[0060] In this embodiment, as Figure 1 and Figure 2 As shown, the inner seat 121 of the furnace cavity enclosure 12 is fixed to the base 23. The two ends of the cavity enclosure 122 of the furnace cavity enclosure 12 are provided with connecting edges 1221. The two ends of the bottom enclosure 24 are fixed to the connecting edges 1221. The upper and lower sides of the bottom enclosure 24 are fixed to the base 23 and the extension 141. The bottom enclosure 24 is stabilized by fixing the two ends of the bottom enclosure 24 with the connecting edges 1221 and fixing the upper and lower sides of the bottom enclosure 24 with the base 23 and the extension 141.

[0061] In this embodiment, both the bottom enclosure 24 and the top enclosure 25 are made of metal materials such as stainless steel. Through the heat dissipation of the ventilation channel 10a and the heat insulation of the heat insulation component 30, it can be ensured that the surface temperature of the bottom enclosure 24 and the top enclosure 25 does not become too high.

[0062] Understandably, the air inlet 21 and the air outlet 22 can be any shape that allows air to enter and exit. The air inlet 21 and the air outlet 22 can be set at any part of the housing 20, as long as air can flow smoothly throughout the ventilation channel 10a. For example, the air inlet 21 and the air outlet 22 can be set at the top and bottom of the housing 20, or both can be set on the side of the housing 20.

[0063] In this embodiment, as Figure 1 and Figure 2 As shown, several air inlets 21 are provided, each air inlet 21 is spaced apart along the periphery of the base 23, so that air can enter the air intake section 11a evenly through the base 23. Each air inlet 21 corresponds to each connecting hole 1411. The air outlet 22 is provided on the side opposite to the insertion port 13 of the top enclosure 25, so that the airflow carrying heat can pass out from this side. Since this side is away from the human body, the air passing through the air outlet 22 will not blow towards the human body.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the top enclosure 25 includes an arc-shaped guide portion 251 and an enclosure portion 252. One side of the arc-shaped guide portion 251 is connected to the extension portion 141, and the other side of the arc-shaped guide portion 251 bends towards the mounting cover 15. The enclosure portion 252 is connected to the side of the arc-shaped guide portion 251 near the mounting cover 15. Specifically, when the airflow flows through the connecting hole 1411 and enters the exhaust section 12a, it will be guided by the arc-shaped guide portion 251. In conjunction with the airflow distribution by the connecting hole 1411, the airflow will smoothly and evenly transition to the exhaust section 12a, effectively avoiding turbulence during the transition of the airflow from the intake section 11a to the exhaust section 12a, thereby ensuring the heat dissipation effect of the exhaust section 12a.

[0065] In this embodiment, the height of the arc-shaped guide portion 251 is lower than the height of the heat insulation component 30.

[0066] In this embodiment, as Figure 1 and Figure 2 As shown, the housing 20 also includes a display screen 26, which is fixed to the top of the top enclosure 25.

[0067] Understandably, the insulation component 30 can be made of any high-temperature resistant insulation material, such as rock wool board, ceramic fiber rigid felt, or aluminum foil foam interlayer. The insulation component 30 can surround the entire surface of the inner shell 10, or surround part of the surface of the inner shell 10, and only needs to provide insulation.

[0068] To prevent a large amount of heat from diffusing to the housing 20 via the mounting cover 15, in some embodiments, the heat insulation member 30 encloses at least a portion of the mounting cover 15. Specifically, since the area of ​​the mounting cover 15 has a higher heat content, by enclosing at least a portion of the mounting cover 15 with the heat insulation member 30, the heat transferred from the mounting cover 15 to the housing 20 can be effectively reduced, thus preventing the housing 20 from overheating.

[0069] In some embodiments, the heat insulation element 30 is at least partially disposed on the side of the reflector 14 near the insertion port 13. Specifically, since the side of the air fryer near the insertion port 13 has more contact with the human body, by partially or entirely disposing of the heat insulation element 30 on the side of the reflector 14 near the insertion port 13, the temperature on that side can be effectively prevented from becoming too high, thus effectively preventing burns to the human body.

[0070] Since the cooking pot 60 is inserted into the cooking cavity 11, to ensure the stability of the cooking pot 60, the inner shell 10 is usually provided with a connecting part 32 to lock the cooking pot 60. This connecting part 32 is located in the ventilation channel 10a and will obstruct airflow. Therefore, to improve the heat insulation effect of this part, in some embodiments, such as Figure 3 , Figure 4 and Figure 5As shown, the heat insulation component 30 includes a heat insulation part 31 and a connecting part 32. The heat insulation part 31 is attached to the side of the mounting cover 15 near the insertion port 13, and the connecting part 32 is disposed on the heat insulation part 31 for connecting the cooking pot 60. Specifically, the connecting part 32 can serve as a locking component. After the cooking pot 60 is inserted into the cooking cavity 11, it connects and locks the cooking pot 60. The heat insulation part 31 can insulate the reflector 14, thereby compensating for the deficiency of insufficient gas flow caused by the connecting part 32, which prevents the heat dissipation from being adequate, thus effectively avoiding excessive local temperature of the outer casing 20 at that location.

[0071] Understandably, the connecting part 32 can be any structure capable of connecting to the cooking container 60. For example, the connecting part 32 can be provided with a locking groove 321 and a micro switch 322, and the top of the cooking container 60 can be provided with a buckle and a push rod corresponding to the locking groove 321 and the micro switch 322. When the cooking container 60 is inserted into the cooking cavity 11, the buckle on the top of the cooking container 60 engages with the locking groove 321, thereby locking the cooking container 60. At this time, the push rod pushes the micro switch 322 to trigger a trigger signal that the cooking container 60 is fully pushed in, indicating that the cooking container 60 has been installed and the food inside the cooking container 60 can be cooked.

[0072] In this embodiment, the lower side of the heat insulation component 30 extends to the reflector 14. The heat insulation component 30 can be fixed to the reflector 14, or fixed to the mounting cover 15, or fixed to both the reflector 14 and the mounting cover 15. It is only necessary to maintain a stable shape and keep it in close contact with the reflector 14.

[0073] In some embodiments, such as Figure 2 and Figure 3 As shown, the housing structure 50 also includes a heating support member 40. One side of the heating support member 40 is connected to and surrounds the mounting cover 15, and the other side of the heating support member 40 extends toward the outer casing 20. Specifically, the heating support member 40 can be used to connect heating components such as fans inside the mounting cover 15, thereby ensuring the stability of the heating components. By extending toward the outer casing 20, the heating support member 40 can guide the airflow toward the outer casing 20, allowing the airflow to fully contact the outer casing 20, thereby reducing the surface temperature of the outer casing 20.

[0074] In this embodiment, the outer side of the heating support 40 extends at an angle away from the cooking cavity 11.

[0075] This application also provides a cooking device, such as... Figure 6 As shown, the device includes a shell structure 50, a cooking pot 60, and a heating component (not shown in the figure). The cooking pot 60 is installed in the cooking cavity 11 of the shell structure 50, and the heating component is installed in the inner shell 10 of the shell structure 50 for supplying heat to the cooking pot 60.

[0076] Specifically, by incorporating this housing structure 50, the cooking equipment can effectively prevent the surface temperature from becoming too high during operation, thereby eliminating the safety hazard of burns to the human body caused by stainless steel cooking equipment during operation and facilitating the use of the cooking equipment.

[0077] In this embodiment, the cooking equipment includes, but is not limited to, air fryers, ovens, steam ovens and fryers, and other cooking equipment that uses high temperatures for cooking.

[0078] In this embodiment, the shell structure 50 may be provided with a single cooking chamber 11, or by forming two or more cooking chambers 11 spaced apart by partitions, the number of cooking pots 60 is adapted to the number of cooking chambers 11.

[0079] For example, the shell structure 50 can be provided with two cooking chambers 11, which are separated by a partition. Correspondingly, there are two cooking pots 60, which are installed in the two cooking chambers 11 respectively. The cooking equipment is provided with burners corresponding to the two cooking chambers 11 respectively. The two burners are separated by a partition and heat the two cooking chambers 11 respectively, so that the cooking work of the two cooking pots 60 does not interfere with each other.

[0080] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein.
