[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0057] See Figure 2 Define the length direction of the cooking device 100 as X, the width direction of the cooking device 100 as Y, and the height direction of the cooking device 100 as Z.

[0058] Combination Figures 1-4The cooking equipment 100 provided in this application embodiment can be an integrated stove, a steam oven, or a steam oven / microwave oven, etc. This application embodiment mainly uses an integrated stove as an example for illustration.

[0059] An integrated cooktop combines the functions of a gas stove, steamer, oven, and steam oven. Because one unit is equivalent to multiple independently functioning kitchen appliances, it allows for simultaneous stir-frying / stewing on the top and steaming / baking below, freeing up kitchen space. Its principle involves using the appliance's heating system to heat water into steam, which is then used to steam food; or using microwaves to heat food; or using air and food for baking.

[0060] In some embodiments, the cooking device 100 includes a host computer and a slave computer. The host computer is equipped with a cooktop, and the slave computer is equipped with an inner pot 110 and components disposed around the inner pot 110, such as a hot air assembly, a magnetron assembly, etc.

[0061] For example, the inner liner 110 has one or more cooking cavities. The cooking cavities can be used to cook food in a steaming mode, a baking mode, or a steam-bake mode.

[0062] The cooking device 100 in this embodiment further includes a liquid supply assembly 120 and a steam assembly 130. The liquid supply assembly 120 includes a liquid storage tank 121 and a connecting pipe 122, and the steam assembly 130 includes a steam generator 131 and a steam supply pipe. The steam generator 131 and the liquid storage tank 121 are connected by the connecting pipe 122, and the steam generator 131 and the cooking chamber are connected by the steam supply pipe. Thus, water stored in the liquid storage tank 121 enters the inner cavity of the steam generator 131 through the connecting pipe 122. The water is heated by the steam generator 131 and converted into high-temperature steam, which then enters the cooking chamber through the steam supply pipe to cook food.

[0063] In some embodiments, the liquid supply assembly 120 is located on the top of the inner pot 110, and the steam generator 131 and part of the steam supply pipe are also located on the top of the inner pot 110, so that the liquid storage tank 121 and the steam generator 131 are connected by the connecting pipe 122, optimizing the pipeline layout of the connecting pipe 122 and reducing the cost of the cooking equipment 100. Furthermore, by arranging the liquid supply assembly 120 and the steam generator 131 on the top of the inner pot 110, the number of components located on the side of the inner pot 110 along the width direction (Y) of the cooking equipment 100 is reduced, thereby reducing the space ratio of the cooking equipment 100 along its own width direction (Y). At the same time, the space on the top of the inner pot 110 is effectively utilized, improving the space utilization rate of the top of the inner pot 110.

[0064] The cooking device 100 in this embodiment further includes an exhaust pipe 140, the inlet of which is connected to the cooking chamber, and the outlet of which is used to discharge gas. During the use of the cooking chamber, the exhaust pipe 140 discharges the steam or gas in the cooking chamber, which stabilizes the pressure in the cooking chamber and prevents excessive pressure from causing accidental damage to the inner pot 110, thereby improving the safety of the cooking device 100.

[0065] It should be noted that, in this embodiment of the application, along the width direction (Y) of the cooking device 100, one side of the inner pot 110 has an opening, which is connected to the cooking cavity, so that the user can put food into the cooking cavity or take food out of the cooking cavity through the opening.

[0066] In some embodiments, along the width direction (Y) of the cooking appliance 100, the exhaust pipe 140 is located on the side of the inner pot 110 opposite to the outlet. Simultaneously, the side of the inner pot 110 opposite to the outlet also houses the blower assembly, flue, etc. On the one hand, the concentration of too many components on the side of the inner pot 110 opposite to the outlet occupies space along the width direction (Y) of the cooking appliance 100. Furthermore, as the volume of the inner pot 110 gradually increases, its size along the width direction (Y) of the cooking appliance 100 also increases, further making it difficult to reduce the space ratio in the width direction (Y) of the cooking appliance 100. On the other hand, since multiple components are located on the side of the inner pot 110 opposite to the outlet, these components can easily compress the exhaust pipe 140 during installation, causing the exhaust pipe 140 to become jammed, resulting in poor exhaust of the cooking appliance 100 and reduced safety.

[0067] Therefore, in this embodiment, the exhaust pipe 140 is at least partially located on the top of the inner pot 110. This makes the structure of the cooking device 100 more compact along its width direction (Y), reducing its space occupancy in that direction. Simultaneously, it avoids interference from components installed on the side of the inner pot 110 away from the opening, facilitating the installation and connection between the exhaust pipe 140 and the inner pot 110. It also reduces the likelihood of the exhaust pipe 140 becoming stuck, ensuring smooth exhaust from the cooking device 100 and further enhancing its safety. Furthermore, placing the exhaust pipe 140 on top of the inner pot 110 improves the space utilization of the top of the inner pot 110.

[0068] As an alternative implementation, the exhaust pipe 140 and the connecting pipe 122 are located on the same side of the inner pot 110 along the width direction (Y) of the cooking device 100. This simplifies the arrangement and installation of the pipes in the cooking device 100, reduces pipe crossings and complex connections, and thus reduces the manufacturing and maintenance difficulty of the cooking device 100.

[0069] In this embodiment, the connecting pipe 122 and the exhaust pipe 140 are spaced apart along the height direction (Z) of the cooking device 100 to prevent the connecting pipe 122 and the exhaust pipe 140 from affecting each other, reduce mutual interference between the connecting pipe 122 and the exhaust pipe 140, avoid mutual compression between the connecting pipe 122 and the exhaust pipe 140, and ensure that both the connecting pipe 122 and the exhaust pipe 140 remain unobstructed.

[0070] For example, in combination Figure 2 and Figure 3 Along the width direction (Y) of the cooking device 100, the exhaust pipe 140 and the connecting pipe 122 are located on the same side of the inner pot 110 away from the outlet.

[0071] In this embodiment, along the width direction (Y) of the cooking device 100, the positions of the exhaust pipe 140 and the connecting pipe 122 can be staggered. That is, the distance between the exhaust pipe 140 and the opening side of the inner pot 110 is less than the distance between the connecting pipe 122 and the opening side of the inner pot 110, or the distance between the exhaust pipe 140 and the opening side of the inner pot 110 is greater than the distance between the connecting pipe 122 and the opening side of the inner pot 110. This embodiment does not make specific requirements in this regard.

[0072] It should be noted that, in this embodiment of the application, along the height direction (Z) of the cooking device 100, the exhaust pipe 140 may be located above the connecting pipe 122. Alternatively, the connecting pipe 122 may be located above the exhaust pipe 140.

[0073] In some embodiments, along the top-to-bottom direction of the cooking appliance 100, the exhaust pipe 140 is located on the side of the connecting pipe 122 near the top of the inner pot 110. That is, along the height direction (Z) of the cooking appliance 100, the exhaust pipe 140 is located below the connecting pipe 122.

[0074] During implementation, if the exhaust pipe 140 and the connecting pipe 122 are staggered along the width direction (Y) of the cooking device 100, the installation of the connecting pipe 122 and the exhaust pipe 140 will be inconvenient, and it will also increase the size of the cooking device 100 in its own width direction (Y). That is to say, the space ratio of the cooking device 100 along the width direction (Y) will increase, which is not conducive to the miniaturization of the cooking device 100.

[0075] Therefore, in the embodiments of the application, the exhaust pipe 140 and the connecting pipe 122 are at least partially arranged opposite each other along the height direction (Z) of the cooking device 100 to reduce the distance between the exhaust pipe 140 and the connecting pipe 122 along the width direction (Y) of the cooking device 100. The structure of the cooking device 100 along the width direction (Y) is compact, thereby reducing the space ratio of the cooking device 100 along the width direction (Y) and contributing to the miniaturization of the cooking device 100.

[0076] In some implementations, combined Figure 2 and Figure 3 The extension direction of the exhaust pipe 140 and the extension direction of the connecting pipe 122 are at least partially parallel. In this embodiment, the parallel arrangement of the exhaust pipe 140 and the connecting pipe 122 makes the installation of the pipeline more intuitive and easier, reduces complex bends and cross connections, thereby reducing the installation difficulty and time, and also reduces the number of bent connectors, thus reducing the cost of the cooking equipment 100.

[0077] It should be noted that the extension direction of the exhaust pipe 140 is the length extension direction of the exhaust pipe 140, and the extension direction of the connecting pipe 122 is the length extension direction of the connecting pipe 122.

[0078] As the cooking equipment 100 becomes more and more functional, and users have different requirements for the cooking modes of the cooking equipment 100, multiple cooking cavities can be set to meet the user's need to operate in different cooking modes at the same time. Therefore, in some embodiments, the cooking cavity includes a first cooking cavity and a second cooking cavity, which are arranged along the length direction (X) of the cooking equipment 100.

[0079] The first cooking chamber can be used to cook food in a steaming mode, and the second cooking chamber can be used to cook food in a steaming / baking mode. Alternatively, both the first and second cooking chambers can be used to cook food in a steaming / baking mode.

[0080] It is easy to understand that the first cooking chamber and the second cooking chamber can be connected to different steam supply pipes and different steam generators 131, so that steam can be introduced into the corresponding first and second cooking chambers through different steam generators 131 to cook food. In this way, the first and second cooking chambers can cook food independently. However, with multiple steam generators 131 and steam pipes that have the same function, it is difficult to improve the integration of the cooking device 100 and reduce costs when they are set up independently.

[0081] Therefore, in this embodiment, the gas supply pipe includes a first gas supply pipe 132 and a second gas supply pipe 133. The first cooking chamber is connected to the steam generator 131 via the first gas supply pipe 132, and the second cooking chamber is connected to the steam generator 131 via the second gas supply pipe 133. In this way, steam is generated by the steam generator 131 and then supplied to the corresponding first and second cooking chambers via the first and second gas supply pipes 132 and 133. This modular design improves the integration of the cooking device 100, reduces its cost, and minimizes its space requirements.

[0082] To facilitate control over the connection between the first cooking chamber and the steam generator 131 via the first gas supply pipe 132, and the connection between the second cooking chamber and the steam generator 131 via the second gas supply pipe 133, allowing the first and second cooking chambers to operate in different modes, a control valve is provided on the steam pipeline in this embodiment. It is easy to understand that this is to facilitate independent control of the on / off states of the first and second gas supply pipes 132 and 133.

[0083] In some embodiments, the steam assembly 130 further includes a first control valve 134 disposed on the first gas supply pipe 132, and the first control valve 134 is used to control the on / off state of the first gas supply pipe 132.

[0084] The first control valve 134 is opened, and the first gas supply pipe 132 connects the first cooking chamber and the steam generator 131. After the steam generator 131 is started, the water in the steam generator 131 is heated and turned into high-temperature steam, which then enters the first cooking chamber through the first gas supply pipe 132 to cook the food in the first cooking chamber.

[0085] When the first control valve 134 is closed and the first gas supply pipe 132 is shut off, the first cooking chamber and the steam generator 131 are not connected, and steam cannot enter the first cooking chamber. The first cooking chamber can be left unused or used to cook food in baking or microwave mode.

[0086] In some embodiments, the steam assembly 130 further includes a second control valve 135 disposed on the second air supply pipe 133, and the second control valve 135 is used to control the on / off state of the second air supply pipe 133.

[0087] The second control valve 135 is opened, and the second air supply pipe 133 connects the second cooking chamber and the steam generator 131. After the steam generator 131 is started, the water in the steam generator 131 is heated and turned into high-temperature steam, which then enters the second cooking chamber through the second air supply pipe 133 to cook the food in the second cooking chamber.

[0088] When the second control valve 135 is closed and the second gas supply pipe 133 is shut off, the second cooking chamber and the steam generator 131 are not connected, and steam cannot enter the second cooking chamber. The second cooking chamber can be turned off or used to cook food in baking or microwave mode.

[0089] In some embodiments, a first control valve 134 is provided on the first gas supply pipe 132, while a second control valve 135 may not be provided on the second gas supply pipe 133. That is, the on / off state of the first gas supply pipe 132 can be controlled by the first control valve 134, so that the first cooking chamber and the steam generator 131 have different communication states, so that non-steaming cooking operations can be completed through the first cooking chamber. In this case, the second cooking chamber can only complete the steaming mode.

[0090] In some embodiments, the first control valve 134 is not provided on the first gas supply pipe 132, but a second control valve 135 may be provided on the second gas supply pipe 133. That is, the on / off state of the second gas supply pipe 133 can be controlled by the second control valve 135, so that the second cooking chamber and the steam generator 131 have different communication states, so that non-steaming cooking operations can be completed through the second cooking chamber. In this case, the first cooking chamber can only complete the steaming mode.

[0091] However, when the steam generator 131 of such cooking device 100 is working, steam is always introduced into one of the first cooking chamber and the second cooking chamber. This results in the steam in the first cooking chamber or the second cooking chamber being wasted when not in use, and the energy consumption of cooking device 100 increases.

[0092] Therefore, see Figure 3 In this embodiment of the application, a first control valve 134 is provided on the first gas supply pipe 132, and a second control valve 135 is provided on the second gas supply pipe. In this way, the first gas supply pipe 132 and the second gas supply pipe 133 can be controlled independently of each other, thereby improving the utilization rate of the steam generated by the steam generator 131 and reducing the energy consumption of the cooking equipment 100.

[0093] The steam operation mode of the cooking device 100 is explained below in conjunction with the functions of the first control valve 134 and the second control valve 135.

[0094] The first control valve 134 is open, the second control valve 135 is closed, and steam can be introduced into the first cooking chamber.

[0095] The first control valve 134 is open, and the second control valve 135 is open, allowing steam to enter both the first and second cooking chambers.

[0096] The first control valve 134 is closed, and the second control valve 135 is open; steam can only be introduced into the second cooking chamber.

[0097] In this way, users can select the first cooking chamber and / or the second cooking chamber for cooking during use, improving the user experience. It should be noted that in this embodiment, when the steam generator 131 is not working, such as in the microwave or grill mode of the cooking device 100, the first control valve 134 and the second control valve 135 remain in the normally open state.

[0098] When the steam generator 131 is started, the first control valve 134 and the second control valve 135 can enter different working states, and the corresponding first gas supply pipe 132 and second gas supply pipe 133 can be in different closed states. It is easy to understand that when the first control valve 134 and the second control valve 135 fail, the first control valve 134 and the second control valve 135 may be closed at the same time. The steam generator 131 is still heating the liquid, and the pressure inside the steam generator 131 cannot be discharged in time. The steam generator 131 is prone to explosion, which reduces the safety of the cooking equipment 100.

[0099] To address this issue, the cooking device 100 in this embodiment further includes a pressure relief pipe 150 and a pressure relief valve 160, with the pressure relief valve 160 and the pressure relief pipe 150 located at the top of the inner liner 110; the pressure relief pipe 150 is connected to the steam generator 131, and the pressure relief valve 160 is disposed on the pressure relief pipe 150, which is used to control the on / off state of the pressure relief pipe 150.

[0100] For example, the pressure relief valve 160 can be a check valve, which may be a spring-loaded check valve.

[0101] When the pressure inside the steam generator 131 is greater than the opening pressure of the pressure relief valve 160, the pressure relief valve 160 opens, and the pressure relief pipe 150 is connected to the steam generator 131, which can discharge the gas in the steam generator 131 to reduce the pressure inside the steam generator 131, thereby improving the safety of the steam generator 131 and the safety of the cooking equipment 100, and extending the service life of the cooking equipment 100.

[0102] It is easy to understand that the first gas supply pipe 132, the second gas supply pipe 133, and the pressure relief pipe 150 all need to be connected to the outlet 1315 of the steam generator 131. If the first gas supply pipe 132, the second gas supply pipe 133, and the pressure relief pipe 150 are connected to the steam generator 131 respectively, the connection process of the cooking equipment 100 is complicated, and the steam generator 131 needs to be equipped with multiple outlets. Such a cooking equipment 100 has low integration and high production cost.

[0103] Therefore, in some embodiments, the steam assembly 130 further includes a four-way connector 136 having an inlet end 1361, a first outlet end 1362, a second outlet end 1363, and a third outlet end 1364; the inlet end 1361 is connected to the steam generator 131, the first outlet end 1362 is connected to the first air supply pipe 132, the second outlet end 1363 is connected to the second air supply pipe 133, and the third outlet end 1364 is connected to the pressure relief pipe 150.

[0104] Thus, in this embodiment of the application, the first gas supply pipe 132, the second gas supply pipe 133 and the pressure relief pipe 150 are connected to the steam generator 131 through the four-way connector 136, which improves the integration of the cooking equipment 100, reduces the number of connecting parts on the steam generator 131, reduces the space ratio of the steam generator 131 and the production cost of the cooking equipment 100, and at the same time, as the space ratio of the steam generator 131 decreases, the space utilization rate of the top of the inner pot 110 increases.

[0105] It is easy to understand that the connecting pipe 122 connects the liquid storage tank 121 and the steam generator 131. With the use of the cooking device 100, there is a possibility of unexpected liquid leakage at the connection between the connecting pipe 122 and the steam generator 131, such as aging of the connecting pipe 122, damage to the connecting pipe 122, or detachment of the connecting pipe 122. In order to prevent the liquid from flowing freely, the cooking device 100 in this embodiment of the application also includes a first liquid blocking component 170. Along the height direction (Z) of the cooking device 100, the first liquid blocking component 170 is disposed between the top of the inner pot 110 and the connecting pipe 122; along the length direction (X) of the cooking device 100, the first liquid blocking component 170 extends to the connection between the connecting pipe 122 and the steam generator 131.

[0106] Thus, after the connecting pipe 122 and the steam generator 131 are accidentally disconnected, the connecting pipe 122 falls to the first liquid blocking element 170, and the first liquid blocking element 170 blocks the water overflowing from the connecting pipe 122 and the steam generator 131, and finally flows through the outer wall of the inner tank 110.

[0107] In some implementations, combined Figure 4 and Figure 5 A heating terminal 190 is provided on the side of the inner pot 110 away from the outlet. The heating terminal 190 is electrically connected to the heating element in the first cooking cavity. The first liquid blocking element 170 can cover the part of the heating terminal 190 outside the inner pot 110 to prevent water from flowing onto the heating terminal 190, thereby further improving the safety of the cooking device 100.

[0108] In some embodiments, the liquid supply assembly 120 further includes an inlet pump 123 and an outlet pump 124, which are spaced apart along the length (X) of the cooking equipment 100. The inlet pump 123 is connected to the liquid storage tank 121, and the outlet pump 123 is connected to the connecting pipe 122. The other end of the connecting pipe 122 is connected to the steam generator 131. Thus, the liquid in the liquid storage tank 121 can be pumped to the steam generator 131 by the inlet pump 123. The inlet pump 123 in this embodiment can provide power for the flow of liquid to increase the flow rate of liquid, so that the liquid can flow quickly and smoothly to the steam generator 131, thereby improving the cooking efficiency of the cooking equipment 100 and further reducing the energy consumption of the cooking equipment 100.

[0109] The inlet of the liquid discharge pump 124 is connected to the connecting pipe 122, and the outlet of the liquid discharge pump 124 is connected to the liquid storage tank 121. It is easy to understand that after the steam generator 131 finishes operating, the liquid discharge pump 124 can discharge the liquid inside the steam generator 131, keeping the inside of the steam generator 131 dry and preventing odors from developing, thus improving the user experience. Furthermore, the liquid discharge pump 124 provides power to the flow of liquid, increasing the flow rate and allowing the liquid to flow quickly and smoothly from the steam generator 131 to the liquid storage tank 121.

[0110] In some embodiments, the liquid supply assembly 120 further includes a three-way connector 125, which has a first connecting end, a second connecting end, and a third connecting end. The first connecting end is connected to the connecting pipe 122, the second connecting end is connected to the outlet end of the inlet pump 123, and the third connecting end is connected to the inlet end 1361 of the outlet pump 124. Thus, by connecting the inlet pump 123, the outlet pump 124, and the connecting pipe 122 through the three-way connector 125, the liquid inlet and outlet of the steam generator 131 are achieved through only one connecting pipe 122, thereby improving the integration of the cooking equipment 100, reducing the number of connecting parts in the cooking equipment 100, and lowering the cost of the cooking equipment 100.

[0111] It is easy to understand that the three-way connector 125 connects the inlet pump 123, the outlet pump 124, and the connecting pipe 122 respectively. With the use of the cooking equipment 100, liquid leakage may occur at each connection point of the three-way connector 125 due to pipe aging, damage, or accidental detachment. To prevent the liquid from flowing freely after leakage, the cooking equipment 100 in this embodiment of the application also includes a second liquid stop 180; along the height direction (Z) of the cooking equipment 100, the second liquid stop 180 is disposed between the top of the inner pot 110 and the three-way connector 125.

[0112] In some embodiments, along the length (X) of the cooking device 100, the second liquid-blocking member 180 extends to the connection between the connecting pipe 122 and the tee connector 125 to block the leakage of liquid at the connection between the connecting pipe 122 and the tee connector 125 and guide the liquid to the outer wall of the inner liner 110.

[0113] And / or, in some embodiments, along the width direction (Y) of the cooking appliance 100, the second liquid stop 180 may also extend to the connection between the tee connector 125 and the inlet pump 123, and the connection between the tee connector 125 and the outlet pump 124. In this way, the second liquid stop 180 can block leaked liquid at the connection between the tee connector 125 and the inlet pump 123, and at the connection between the tee connector 125 and the outlet pump 124, and guide that portion of the liquid to the outer wall of the inner liner 110.

[0114] See Figure 4 A heating terminal 190 is provided on the side of the inner pot 110 away from the outlet. The heating terminal 190 is electrically connected to the heating element in the second cooking cavity. The second liquid blocking element 180 can cover the part of the heating terminal 190 on the outside of the inner pot 110 to prevent water from flowing onto the heating terminal 190, thereby further improving the safety of the cooking equipment 100.

[0115] In some implementations, combined Figures 6-8 The steam generator 131 has a receiving cavity and a partition plate 1311 disposed within the receiving cavity. Along the height direction (Z) of the cooking equipment 100, the partition plate 1311 divides the receiving cavity into a steam chamber 1312 and a heating chamber 1313. The partition plate 1311 has a through hole 1314 to allow steam generated in the heating chamber 1313 to enter the steam chamber 1312. The outlet 1315 of the steam generator 131 communicates with the steam chamber 1312. Along the height direction (Z) of the cooking equipment 100, the outlet 1315 of the steam generator 131 is located at the top of the steam generator 131. The outlet 1315 of the steam generator 131 communicates with the inlet of the four-way connector 136 to discharge steam from the steam chamber 1312.

[0116] See Figure 8 The first direction is defined as the P direction. It should be noted that, in this embodiment of the application, the first direction is described as being along the length of the steam generator 131.

[0117] When the water in the heating chamber 1313 boils, some of the liquid is carried into the steam chamber 1312, and further carried out from the outlet 1315 of the steam generator 131 by the flow of steam. To prevent the liquid from flowing into the steam generator 131 after boiling, in this embodiment, the outlet 1315 and the through hole 1314 of the steam generator 131 are located on different sides of the steam generator 131 along a first direction (P); wherein, the first direction (P) is along the length or width direction of the steam generator 131. In this way, by increasing the distance between the outlet 1315 and the through hole 1314, the relative positions of the outlet 1315 and the through hole 1314 are adjusted so that after the liquid boils, it flows in the steam chamber 1312 and finally collects in the steam chamber 1312, thereby preventing the liquid from being carried out from the outlet 1315 of the steam generator 131.

[0118] The cooking apparatus 100 provided in this application embodiment includes: an inner pot 110, a liquid supply assembly 120, a steam assembly 130, and an exhaust pipe 140. The inner pot 110 has a cooking cavity; the liquid supply assembly 120 is located at the top of the inner pot 110, and the liquid supply assembly 120 includes a liquid storage tank 121 and a connecting pipe 122; the steam assembly 130 includes a steam generator 131 and a steam supply pipe, the steam generator 131 is located at the top of the inner pot 110, the steam generator 131 and the liquid storage tank 121 are connected through the connecting pipe 122, and the steam generator 131 and the cooking cavity are connected through the steam supply pipe; at least a portion of the exhaust pipe 140 is located at the top of the inner pot 110; the inlet of the exhaust pipe 140 is connected to the cooking cavity, and the outlet of the exhaust pipe 140 is used for gas discharge. By placing the exhaust pipe 140 at the top of the inner pot 110, the utilization rate of the top space of the inner pot 110 is improved. At the same time, the space ratio of the cooking device 100 in the width direction can be reduced, and the exhaust pipe 140, the gas supply pipe and the connecting pipe 122 can be prevented from getting stuck, so that the gas and / or liquid flow smoothly and the reliability and stability of the cooking device 100 are improved.
