[0086] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0089] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0090] This application discloses a cooking device, combined with Figures 1 to 8 As shown, in some embodiments, the cooking device includes a cooking chamber 1100, a steam generator 5000, a combustion device 3000, and a gas path regulating device 4000. The steam generator 5000 is adapted to generate steam that flows to the cooking chamber 1100. The combustion device 3000 is adapted to supply gas for combustion to generate flue gas. The gas path regulating device 4000 is adapted to connect the cooking chamber 1100 and the combustion device 3000, and is also adapted to isolate the cooking chamber 1100 and the combustion device 3000. When the gas path regulating device 4000 connects the cooking chamber 1100 and the combustion device 3000, the flue gas generated by the combustion device 3000 is adapted to flow to the cooking chamber 1100 through the gas path regulating device 4000.

[0091] The cooking cavity 1100 is a space for placing food ingredients. Generally, the cooking cavity 1100 has an opening on the front side. The cooking device has a door 8000, which can move between an open position and a closed position. When the door 8000 moves to the closed position, it closes the opening. When the door 8000 moves to the open position, it opens the opening.

[0092] The steam generator 5000 is a component for generating steam. In this embodiment, steam refers to water vapor. The steam generator 5000 is connected to the cooking cavity 1100, and the steam generated by the steam generator 5000 is suitable for being directed to the cooking cavity 1100.

[0093] The combustion device 3000 generates flue gas based on the combustion of gas. That is, the flue gas is a high-temperature gas flow generated by the combustion of gas. For example, the combustion device 3000 includes a burner 3100. After the gas is sprayed out through the burner 3100, it is ignited to form a flame. Flue gas is generated during the continuous combustion of the gas.

[0094] During baking and cooking, the ingredients are placed in the cooking chamber 1100. The gas path regulating device 4000 connects the cooking chamber 1100 and the combustion device 3000. The flue gas generated by the combustion device 3000 is input into the cooking chamber 1100 through the gas path regulating device 4000, thereby realizing the baking and cooking of the ingredients.

[0095] When steam cooking is performed, the food is placed in the cooking chamber 1100, and steam is input into the cooking chamber 1100. The gas path regulating device 4000 isolates the cooking chamber 1100 from the combustion device 3000. The steam input into the cooking chamber 1100 will not enter the combustion device 3000 through the gas path regulating device 4000. This achieves steam cooking of the food without affecting the subsequent operation of the combustion device 3000.

[0096] Optionally, in some embodiments, the gas path regulating device 4000 has a first state and a second state; the gas path regulating device 4000 is adapted to connect the combustion device 3000 and the cooking cavity 1100 when it is in the first state; the gas path regulating device 4000 is adapted to disconnect the combustion device 3000 and the cooking cavity 1100 when it is in the second state.

[0097] Isolation refers to the disconnection of a passage, while connection refers to the opening of a channel. During baking / cooking, the food is placed in the cooking chamber 1100, and the gas path regulating device 4000 switches to its first state, connecting the cooking chamber 1100 and the combustion device 3000. The flue gas generated by the combustion device 3000 enters the cooking chamber 1100 through the gas path regulating device 4000, thus achieving baking / cooking of the food. During steam cooking, the food is placed in the cooking chamber 1100, and steam is input into the cooking chamber 1100. The gas path regulating device 4000 switches to its second state, isolating the cooking chamber 1100 and the combustion device 3000. The steam input into the cooking chamber 1100 will not enter the combustion device 3000 through the gas path regulating device 4000, thus achieving steam cooking of the food without affecting the subsequent operation of the combustion device 3000.

[0098] The gas path regulating device 4000 controls the connection and isolation between the combustion device 3000 and the cooking cavity 1100 through the following scheme, combined with Figures 8 to 13 As shown, in some embodiments, the gas path regulating device 4000 is provided with a first smoke inlet 4110. The gas path regulating device 4000 is adapted to open the first smoke inlet 4110 when it is in a first state. The combustion device 3000 is adapted to communicate with the cooking chamber 1100 through the first smoke inlet 4110. The flue gas generated by the combustion device 3000 flows to the cooking chamber 1100 through the first smoke inlet 4110. The gas path regulating device 4000 is adapted to close the first smoke inlet 4110 when it is in a second state. The steam from the steam generator 5000 to the cooking chamber 1100 cannot flow to the combustion device 3000 through the first smoke inlet 4110.

[0099] The structure of the air path regulating device 4000 is as follows, combined with Figures 8 to 13As shown, in some embodiments, the gas path regulating device 4000 includes a first housing 4100, a second housing 4200, and a drive mechanism 4300. The first housing 4100 is provided with a first smoke inlet 4110. The second housing 4200 is movably disposed. The drive mechanism 4300 is connected to the second housing 4200 to be adapted to drive the second housing 4200 to a first position and a second position. The second housing 4200 is adapted to open the first smoke inlet 4110 when it is moved to the first position, so that the gas path regulating device 4000 is in a first state. The second housing 4200 is adapted to close the first smoke inlet 4110 when it is moved to the second position, so that the gas path regulating device 4000 is in a second state.

[0100] The drive mechanism 4300 is used to output mechanical energy to move the second housing 4200. For example, the drive mechanism 4300 can convert electrical energy into mechanical energy to drive the second housing 4200 to move. The movement of the second housing 4200 can take various forms, including but not limited to translation, extension, and deformation. When the drive mechanism 4300 moves the second housing 4200 to the first position, the second housing 4200 opens the first smoke inlet 4110, and the flue gas generated by the combustion device 3000 can flow through the first smoke inlet 4110 into the cooking chamber 1100. When the drive mechanism 4300 moves the second housing 4200 to the second position, the second housing 4200 closes the first smoke inlet 4110, and the steam from the steam generator 5000 to the cooking chamber 1100 cannot flow to the combustion device 3000 through the first smoke inlet 4110. The second housing 4200 is moved to the first position and the second position by the drive mechanism 4300, so that the second housing 4200 can be moved to the first position and the second position, so as to facilitate the opening and closing of the first smoke inlet 4110.

[0101] Combination Figures 8 to 13 As shown, in some embodiments, the second housing 4200 includes a first blocking portion 4210. The first blocking portion 4210 is adapted to be offset from the first smoke inlet 4110 when the second housing 4200 is moved to a first position to open the first smoke inlet 4110, and is also adapted to be opposite to the first smoke inlet 4110 when the second housing 4200 is moved to a second position to close the first smoke inlet 4110. Based on the movable configuration of the second housing 4200, the first blocking portion 4210 moves with the second housing 4200. By providing the first blocking portion 4210, it is convenient to open and close the first smoke inlet 4110.

[0102] Combination Figures 8 to 13As shown, in some embodiments, the second housing 4200 further includes a first communication port 4230, which is adapted to connect to the first smoke inlet 4110 to open the first smoke inlet 4110 when the first shielding portion 4210 and the first smoke inlet 4110 are misaligned. When the second housing 4200 moves to the first position, the first shielding part 4210 and the first smoke inlet 4110 are misaligned, and the first connecting port 4230 and the first smoke inlet 4110 are opposite to each other, thus connecting the first smoke inlet 4110. In this way, the first smoke inlet 4110 is opened, and the flue gas generated by the combustion device 3000 flows to the cooking chamber 1100 through the first smoke inlet 4110. When the second housing 4200 moves to the second position, the first shielding part 4210 and the first smoke inlet 4110 are opposite to each other, and the first connecting port 4230 and the first smoke inlet 4110 are misaligned, thus closing the first smoke inlet 4110. The steam generated by the steam generator 5000 enters the cooking chamber 1100 and cannot flow to the combustion device 3000 through the first smoke inlet 4110.

[0103] Optionally, the number of the first smoke inlet 4110, the first connecting port 4230, and the first shielding part 4210 are multiple, which can increase the flow area.

[0104] Combination Figures 1 to 8 As shown, in some embodiments, the cooking device further includes a heat preservation cavity 2100, and the gas path regulating device 4000 is adapted to isolate the heat preservation cavity 2100 and the combustion device 3000 when the cooking cavity 1100 and the combustion device 3000 are connected, and is also adapted to connect the heat preservation cavity 2100 and the combustion device 3000 when the cooking cavity 1100 and the combustion device 3000 are isolated.

[0105] When the gas path regulating device 4000 connects the heat preservation cavity 2100 and the combustion device 3000, the flue gas generated by the combustion device 3000 is suitable for passing through the gas path regulating device 4000 to the heat preservation cavity 2100, so that the heat preservation cavity 2100 transfers heat towards the cooking cavity 1100. The heat preservation cavity 2100 is suitable for transferring heat to the cooking cavity 1100. For example, the heat preservation cavity 2100 is located on the outside of the cooking cavity 1100 and is in close contact with the cooking cavity 1100. The heat preservation cavity 2100 can transfer heat to the cooking cavity 1100, thereby achieving heat preservation / auxiliary heating of the cooking cavity 1100.

[0106] During baking and cooking, the ingredients are placed in the cooking chamber 1100. The gas path regulating device 4000 connects the cooking chamber 1100 and the combustion device 3000 and separates the heat preservation chamber 2100 and the combustion device 3000. The flue gas generated by the combustion device 3000 is input into the cooking chamber 1100 through the gas path regulating device 4000, thereby realizing the baking and cooking of the ingredients.

[0107] During steam cooking, the ingredients are placed in the cooking chamber 1100, and steam is input into the cooking chamber 1100. The gas path regulating device 4000 separates the cooking chamber 1100 from the combustion device 3000 and connects the heat preservation chamber 2100 and the combustion device 3000. The steam generated by the steam generator 5000 is input into the cooking chamber 1100 without passing through the gas path regulating device 4000 into the combustion device 3000. The flue gas generated by the combustion device 3000 passes through the gas path regulating device 4000 to the heat preservation chamber 2100. The heat preservation chamber 2100 provides heat preservation / auxiliary heating for the cooking chamber 1100, reduces the condensation of steam in the cooking chamber 1100, and helps to improve cooking efficiency and cooking results.

[0108] Optionally, in some embodiments, the gas path regulating device 4000 is adapted to switch between a first state and a second state. When the gas path regulating device 4000 is in the first state, the combustion device 3000 and the cooking chamber 1100 are connected, while the combustion device 3000 and the heat preservation chamber 2100 are disconnected. The connection between the combustion device 3000 and the cooking chamber 1100 allows the flue gas generated by the combustion device 3000 to flow into the cooking chamber 1100. When the gas path regulating device 4000 is in the second state, the combustion device 3000 and the cooking chamber 1100 are disconnected, while the combustion device 3000 and the heat preservation chamber 2100 are connected. The connection between the combustion device 3000 and the heat preservation chamber 2100 allows the flue gas generated by the combustion device 3000 to flow into the heat preservation chamber 2100, and the steam generated by the steam generator 5000 is input into the cooking chamber 1100 without entering the combustion device 3000 through the gas path regulating device 4000.

[0109] The combustion device 3000 is connected to the cooking chamber 1100 / heat preservation chamber 2100, meaning that the flue gas generated by the combustion device 3000 can flow through the gas path regulating device 4000 and then to the cooking chamber 1100 / heat preservation chamber 2100. For example, the combustion device 3000 includes a combustion chamber 3200 and a burner 3100. The burner 3100 is disposed in the combustion chamber 3200. Gas is introduced into the burner 3100 and sprayed towards the combustion chamber 3200 to be ignited and form a flame. The flame is generated in the combustion chamber 3200, and flue gas is formed in this process. The flue gas is discharged from the combustion chamber 3200. When the combustion device 3000 and the cooking chamber 1100 are connected, the combustion chamber 3200 is connected to the cooking chamber 1100 through the gas path regulating device 4000. The flue gas is discharged from the combustion chamber 3200 and flows through the gas path regulating device 4000 to the cooking chamber 1100. When the combustion device 3000 and the heat preservation chamber 2100 are connected, the combustion chamber 3200 is connected to the heat preservation chamber 2100 through the gas path regulating device 4000. The flue gas is discharged from the combustion chamber 3200 and flows through the gas path regulating device 4000 to the heat preservation chamber 2100.

[0110] The combustion device 3000 and the cooking chamber 1100 / heat preservation chamber 2100 are isolated, that is, the gas path regulating device 4000 separates the combustion device 3000 from the cooking chamber 1100 / heat preservation chamber 2100. The flue gas generated by the combustion device 3000 cannot flow through the gas path regulating device 4000 to the cooking chamber 1100 / heat preservation chamber 2100. It is worth noting that when food is placed in the cooking chamber 1100 for cooking and the gas path regulating device 4000 is in its second state, because the gas path regulating device 4000 isolates the combustion device 3000 from the cooking chamber 1100, the moisture in the cooking chamber 1100 cannot enter the combustion device 3000 through the gas path regulating device 4000 while the food is being cooked, thus preventing any impact on the subsequent operation of the combustion device 3000. During baking and cooking, the ingredients are placed in the cooking chamber 1100, and the gas path regulating device 4000 is switched to the first state to connect the cooking chamber 1100 and the combustion device 3000 and isolate the heat preservation chamber 2100 and the combustion device 3000. The flue gas generated by the combustion device 3000 is input into the cooking chamber 1100 through the gas path regulating device 4000, thereby realizing the baking and cooking of the ingredients.

[0111] During steam cooking, the ingredients are placed in the cooking chamber 1100, and steam is input into the cooking chamber 1100. The gas path regulating device 4000 switches to the second state, thereby isolating the cooking chamber 1100 from the combustion device 3000 and connecting the heat preservation chamber 2100 and the combustion device 3000. The steam generated by the steam generator 5000 is input into the cooking chamber 1100 without passing through the gas path regulating device 4000 into the combustion device 3000 and the heat preservation chamber 2100. The flue gas generated by the combustion device 3000 is input into the heat preservation chamber 2100 through the gas path regulating device 4000. The heat preservation chamber 2100 can transfer heat to the cooking chamber 1100, which plays a role in heat preservation / auxiliary heating for steam cooking, reduces steam condensation, helps to improve cooking efficiency, and improves cooking results.

[0112] The gas path regulating device 4000 controls the connection and isolation between the combustion device 3000 and the cooking cavity 1100 / heat preservation cavity 2100 through the following scheme, combined with Figures 8 to 13As shown, in some embodiments, the gas path regulating device 4000 includes a first smoke inlet 4110 and a second smoke inlet 4120. The gas path regulating device 4000 is adapted to open the first smoke inlet 4110 and close the second smoke inlet 4120 when in a first state. The combustion device 3000 is adapted to communicate with the cooking chamber 1100 through the first smoke inlet 4110. The flue gas generated by the combustion device 3000 flows through the first smoke inlet 4110 to the cooking chamber 1100. Since the second smoke inlet 4120 is closed, the flue gas generated by the combustion device 3000 cannot flow through the second smoke inlet 4120 to the heat preservation chamber 2100. The gas flow regulating device 4000 is adapted to close the first smoke inlet 4110 and open the second smoke inlet 4120 when in the second state. The combustion device 3000 is adapted to be connected to the heat preservation chamber 2100 through the second smoke inlet 4120. The flue gas generated by the combustion device 3000 flows to the heat preservation chamber 2100 through the second smoke inlet 4120. Since the first smoke inlet 4110 is closed, the flue gas generated by the combustion device 3000 cannot flow to the cooking chamber 1100 through the first smoke inlet 4110. The steam generated by the steam generator 5000 flows to the cooking chamber 1100 and then cannot flow to the heat preservation chamber 2100 and the combustion device 3000 through the first smoke inlet 4110. The arrangement of the first smoke inlet 4110 and the second smoke inlet 4120 facilitates the connection and isolation between the combustion device 3000 and the cooking chamber 1100 / heat preservation chamber 2100.

[0113] The structure of the air path regulating device 4000 is as follows, combined with Figures 8 to 13 As shown, in some embodiments, the gas path regulating device 4000 includes a first housing 4100, a second housing 4200, and a drive mechanism 4300. The first housing 4100 is provided with the aforementioned first smoke inlet 4110 and second smoke inlet 4120. The second housing 4200 is movably disposed. The drive mechanism 4300 is connected to the second housing 4200. The drive mechanism 4300 can drive the second housing 4200 to move to a first position and a second position. When the drive mechanism 4300 drives the second housing 4200 to move to the first position, the second housing 4200 opens the first smoke inlet 4110 and closes the second smoke inlet 4120. At this time, the gas path regulating device 4000 is in the first state. When the drive mechanism 4300 drives the second housing 4200 to move to the second position, the second housing 4200 closes the first smoke inlet 4110 and opens the second smoke inlet 4120. At this time, the gas path regulating device 4000 is in the second state.

[0114] The drive mechanism 4300 is used to output mechanical energy to make the second housing 4200 move. For example, the drive mechanism 4300 can convert electrical energy into mechanical energy to drive the second housing 4200 to move. The second housing 4200 can move in various ways, including but not limited to translation, extension, and deformation. When the drive mechanism 4300 moves the second housing 4200 to the first position, the second housing 4200 opens the first smoke inlet 4110 and closes the second smoke inlet 4120. The flue gas generated by the combustion device 3000 can flow through the first smoke inlet 4110 into the cooking chamber 1100 but cannot flow through the second smoke inlet 4120 into the heat preservation chamber 2100. When the drive mechanism 4300 moves the second housing 4200 to the second position, the second housing 4200 closes the first smoke inlet 4110 and opens the second smoke inlet 4120. The flue gas generated by the combustion device 3000 can flow through the second smoke inlet 4120 into the heat preservation chamber 2100 but cannot flow through the first smoke inlet 4110 into the cooking chamber 1100. The steam generated by the steam generator 5000, after passing through the cooking chamber 1100, cannot flow through the first smoke inlet 4110 but flows into the heat preservation chamber 2100 and the combustion device 3000. The second housing 4200 is moved to the first position and the second position by the drive mechanism 4300, so that the second housing 4200 can be moved to the first position and the second position, so as to facilitate the opening and closing of the first smoke inlet 4110 / second smoke inlet 4120.

[0115] The opening and closing of the first smoke inlet 4110 is achieved through the following scheme, combined with Figures 8 to 13 As shown, in some embodiments, the second housing 4200 includes a first blocking portion 4210. The first blocking portion 4210 is adapted to be offset from the first smoke inlet 4110 when the second housing 4200 is moved to a first position to open the first smoke inlet 4110, and is also adapted to be opposite to the first smoke inlet 4110 when the second housing 4200 is moved to a second position to close the first smoke inlet 4110. Based on the movable configuration of the second housing 4200, the first blocking portion 4210 moves with the second housing 4200. By providing the first blocking portion 4210, it is convenient to open and close the first smoke inlet 4110.

[0116] Similarly, the opening and closing of the second smoke inlet 4120 is achieved through the following scheme, combined with... Figures 8 to 13As shown, in some embodiments, the second housing 4200 includes a second blocking portion 4220. The second blocking portion 4220 is adapted to be opposite to the second smoke inlet 4120 to close the second smoke inlet 4120 when the second housing 4200 is moved to a first position, and is also adapted to be offset from the second smoke inlet 4120 to open the second smoke inlet 4120 when the second housing 4200 is moved to a second position. Based on the movable configuration of the second housing 4200, the second blocking portion 4220 moves with the second housing 4200. By providing the second blocking portion 4220, it is convenient to open and close the second smoke inlet 4120.

[0117] Combination Figures 8 to 13 As shown, in some embodiments, the second housing 4200 further includes a first communication port 4230, which is adapted to connect to the first smoke inlet 4110 to open the first smoke inlet 4110 when the first shielding portion 4210 and the first smoke inlet 4110 are misaligned. When the second housing 4200 moves to the first position, the first shielding part 4210 and the first smoke inlet 4110 are misaligned, and the first connecting port 4230 and the first smoke inlet 4110 are opposite to each other, thus connecting the first smoke inlet 4110. In this way, the first smoke inlet 4110 is opened, and the flue gas generated by the combustion device 3000 passes through the first smoke inlet 4110 to the cooking chamber 1100. When the second housing 4200 moves to the second position, the first shielding part 4210 and the first smoke inlet 4110 are opposite to each other, and the first connecting port 4230 and the first smoke inlet 4110 are misaligned, thus closing the first smoke inlet 4110. The flue gas generated by the combustion device 3000 cannot pass through the first smoke inlet 4110 to the cooking chamber 1100, and the steam generated by the steam generator 5000, after passing through the cooking chamber 1100, cannot flow through the first smoke inlet 4110 but instead flows to the heat preservation chamber 2100 and the combustion device 3000.

[0118] The second housing 4200 also includes a second communication port 4240, which is adapted to connect to the second smoke inlet 4120 to open the second smoke inlet 4120 when the second shielding portion 4220 and the second smoke inlet 4120 are misaligned. When the second housing 4200 is moved to the first position, the second shielding part 4220 and the second smoke inlet 4120 are opposite to each other, and the second connecting port 4240 and the second smoke inlet 4120 are staggered. In this way, the second smoke inlet 4120 is closed, and the flue gas generated by the combustion device 3000 cannot pass through the second smoke inlet 4120 to the heat preservation cavity 2100. When the second housing 4200 is moved to the second position, the second shielding part 4220 and the second smoke inlet 4120 are staggered, and the second connecting port 4240 and the second smoke inlet 4120 are opposite to each other, thereby connecting the second smoke inlet 4120. In this way, the second smoke inlet 4120 is opened, and the flue gas generated by the combustion device 3000 passes through the second smoke inlet 4120 to the heat preservation cavity 2100.

[0119] Optionally, the number of the first smoke inlet 4110, the second smoke inlet 4120, the first connecting port 4230, the second connecting port 4240, the first shielding part 4210, and the second shielding part 4220 are multiple, which can increase the flow area.

[0120] Combination Figures 8 to 13 As shown, in some embodiments, the second housing 4200 is rotatably configured, and the drive mechanism 4300 is adapted to drive the second housing 4200 to rotate to a first position and a second position. That is, the movement of the second housing 4200 is rotation. The rotatable configuration of the second housing 4200 makes it easier to achieve position changes in a limited space, which helps to simplify the structure. Based on the rotatable configuration of the second housing 4200, since the second housing 4200 needs to rotate to the first position and the second position to switch the first state and the second state of the air path regulating device 4000, the drive mechanism 4300 drives the second housing 4200 to rotate back and forth, which helps to further simplify the structure. For example, the drive mechanism 4300 drives the second housing 4200 to rotate clockwise to the first position, so that the air path regulating device 4000 is in the first state; the drive mechanism 4300 drives the second housing 4200 to rotate counterclockwise to the second position, so that the air path regulating device 4000 is in the second state.

[0121] Since the second housing 4200 needs to open and close the first smoke inlet 4110 / second smoke inlet 4120, and since the second housing 4200 is configured to be rotatable, in some embodiments, the second housing 4200 and the first housing 4100 are rotatably connected to achieve a better fit. For example, the first housing 4100 is fixed, and the second housing 4200 is rotatably connected to the first housing 4100, allowing the second housing 4200 to rotate relative to the first housing 4100 to a first position and a second position. The rotatable connection between the second housing 4200 and the first housing 4100 can be achieved in various ways, such as by riveting. This arrangement ensures the rotatability of the second housing 4200 and facilitates the opening and closing (sealing) of the first smoke inlet 4110 / second smoke inlet 4120.

[0122] Combination Figures 8 to 13As shown, in some embodiments, the first housing 4100 is provided with a first cavity 4101, and the second housing 4200 is rotatably disposed in the first cavity 4101. The second housing 4200 is provided with a second cavity 4201 that is open away from the first cavity 4101. The second cavity 4201 is adapted to receive the flue gas generated by the combustion device 3000, and the second cavity 4201 is adapted to communicate with the first smoke inlet 4110 when the second housing 4200 is rotated to the first position, and is adapted to communicate with the second smoke inlet 4120 when the second housing 4200 is rotated to the second position.

[0123] The second housing 4200 is rotatably disposed in the first cavity 4101. When the second housing 4200 is rotated to the first position, the first smoke inlet 4110 is opened and the second smoke inlet 4120 is closed. The first smoke inlet 4110 and the second cavity 4201 are connected. The flue gas generated by the combustion device 3000 first enters the second cavity 4201 and then flows to the cooking cavity 1100 through the first smoke inlet 4110. When the second housing 4200 is rotated to the second position, the first smoke inlet 4110 is closed and the second smoke inlet 4120 is opened. The second smoke inlet 4120 and the second cavity 4201 are connected. The flue gas generated by the combustion device 3000 first enters the second cavity 4201 and then flows to the heat preservation cavity 2100 through the second smoke inlet 4120.

[0124] The second concave cavity 4201 receives the flue gas generated by the combustion device 3000 as follows: The combustion device 3000 includes a combustion chamber 3200 and a burner 3100. The burner 3100 is disposed in the combustion chamber 3200. The combustion chamber 3200 and the second concave cavity 4201 are connected. When the flue gas generated by the combustion of the gas is discharged from the combustion chamber 3200, it enters the second concave cavity 4201. When the second housing 4200 opens the first smoke inlet 4110 and closes the second smoke inlet 4120, the flue gas flows through the first smoke inlet 4110 into the cooking chamber 1100. When the second housing 4200 closes the first smoke inlet 4110 and opens the second smoke inlet 4120, the flue gas flows through the second smoke inlet 4120 into the heat preservation chamber 2100. The second concave cavity 4201 is designed to more conveniently cooperate with the combustion device 3000 to receive the flue gas generated by the combustion device 3000.

[0125] With the first housing 4100 having a first recess 4101 and the second housing 4200 having a second recess 4201, the bottom wall of the first housing 4100 (the bottom of the first recess 4101) is provided with a first smoke inlet 4110, the peripheral wall of the first housing 4100 (the peripheral side of the first recess 4101) is provided with a second smoke inlet 4120, the bottom wall of the second housing 4200 (the bottom of the second recess 4201) is provided with a first shielding part 4210, and its (referring to the second housing 4200) peripheral wall (the peripheral side of the second recess 4201) is provided with a second shielding part 4220. Alternatively, the bottom wall of the first housing 4100 (the bottom of the first cavity 4101) is provided with a first smoke inlet 4110, the peripheral wall of the first housing 4100 (the peripheral side of the first cavity 4101) is provided with a second smoke inlet 4120, the bottom wall of the second housing 4200 (the bottom of the second cavity 4201) is provided with a first shielding part 4210 and a first connecting port 4230, and its (referring to the second housing 4200) peripheral wall (the peripheral side of the second cavity 4201) is provided with a second shielding part 4220 and a second connecting port 4240. Thus, the flue gas entering the cooking chamber 1100 from the first smoke inlet 4110 flows roughly along the axial direction of the airflow regulating device 4000, and the flue gas entering the heat preservation chamber 2100 from the second smoke inlet 4120 flows roughly along the radial direction of the airflow regulating device 4000 (the extension direction of the rotation axis of the second housing 4200 is axial). This arrangement is more conducive to the coordination between the airflow regulating device 4000 and the cooking chamber 1100 and the heat preservation chamber 2100 when the heat preservation chamber 2100 is located outside the cooking chamber 1100.

[0126] Combination Figures 8 to 11As shown, in some embodiments, the second housing 4200 is provided with a connecting arm 4250 extending away from the rotation center of the second housing 4200. The drive mechanism 4300 is coupled to the connecting arm 4250 to drive the second housing 4200 to rotate. As described above, the gas path regulating device 4000 is used to regulate the flow of flue gas to either the cooking chamber 1100 or the heat preservation chamber 2100. That is, the flue gas needs to flow through the gas path regulating device 4000. The flue gas has a high temperature. To minimize the contact between the flue gas and the drive mechanism 4300, in this embodiment, the second housing 4200 is provided with a connecting arm 4250 extending away from the rotation center of the second housing 4200. The drive mechanism 4300 is coupled to the connecting arm 4250, thereby driving the second housing 4200 to rotate. Since the connecting arm 425 is far from the rotation center of the second housing 4200, the drive mechanism 4300 can be set at a position far from the rotation center of the second housing 4200. Since the second housing 4200 is used to open and close the first smoke inlet 4110 and the second smoke inlet 4120, that is, the flue gas needs to flow through the second housing 4200, by setting it as described above, the drive mechanism 4300 is far from the second housing 4200, which can avoid the flue gas from contacting the drive mechanism 4300 as much as possible, and also avoid blocking the flue gas from entering the second cavity 4201.

[0127] Combination Figures 8 to 11 As shown, in some embodiments, the drive mechanism 4300 includes a motor 4310, a lever 4320, and a pin 4330. The motor 4310 includes a drive shaft 4311. The lever 4320 is disposed on the drive shaft 4311 and can rotate with the drive shaft 4311. The pin 4330 is disposed on the lever 4320 and can rotate with the lever 4320. The connecting arm 4250 is provided with a slot 4251. The pin 4330 is inserted into the slot 4251 to couple with the connecting arm 4250. The pin 4330 is adapted to move in the extension direction of the slot 4251 when driving the second housing 4200 to rotate. In this embodiment, the lever 4320 extends approximately away from the rotation axis of the drive shaft 4311. When the drive shaft 4311 of the motor 4310 rotates, it drives the lever 4320 to rotate as well, thereby causing the pin 4330 to rotate as well. The slot 4251 has a certain extension length, and the pin 4330 can move along the extension direction of the slot 4251 when it rotates as well, synchronously driving the second housing 4200 to rotate.

[0128] Optionally, combined Figures 8 to 11 as well as Figure 14 , Figure 15As shown, in some embodiments, at least a portion of the connecting arm 4250 is located in the heat preservation cavity 2100, the motor 4310 and the lever 4320 are located outside the cooking cavity 1100 and the heat preservation cavity 2100, the cavity wall of the heat preservation cavity 2100 is provided with an arc-shaped groove 2300, the drive mechanism 4300 also includes a baffle 4340, the baffle 4340 is rotatably disposed and covers the arc-shaped groove 2300, the pin 4330 passes through the baffle 4340 and the arc-shaped groove 2300, the pin 4330 can drive the baffle 4340 to rotate with it, and is adapted to move along the extension direction of the arc-shaped groove 2300.

[0129] The motor 4310 is located on the outer wall of the cooking cavity 1100 and the heat preservation cavity 2100 to avoid direct exposure to heat and / or moisture. In this embodiment, at least a portion of the connecting arm 4250 extends into the heat preservation cavity 2100. To enable the motor 4310 to drive the connecting arm 4250, an arc-shaped groove 2300 is provided in the cavity wall (hereinafter, the surrounding plate 2000) of the heat preservation cavity 2100. The pin 4330 needs to pass through the arc-shaped groove 2300 to couple with the connecting arm 4250. When the drive shaft 4311 of the motor 4310 rotates, The pin 4330 moves along the arc-shaped groove 2300. To prevent the flue gas entering the insulation cavity 2100 from leaking out of the arc-shaped groove 2300, a rotatable baffle 4340 is provided. The baffle 4340 covers the arc-shaped groove 2300 to form a seal. The pin 4330 also passes through the baffle 4340. When the pin 4330 drives the second housing 4200 to rotate, the pin 4330 synchronously drives the baffle 4340 to rotate as well. This ensures that the baffle 4340 covers and seals the arc-shaped groove 2300 during the rotation process.

[0130] Since the baffle 4340 is rotatable and needs to cover and seal the arc-shaped groove 2300, to improve the fit between the baffle 4340 and the arc-shaped groove 2300, optionally, the baffle 4340 and the cavity wall (hereinafter referred to as the enclosure plate 2000) of the insulation cavity 2100 can be rotatably connected, thus achieving a tighter fit between the baffle 4340 and the arc-shaped groove 2300. There are several ways to achieve a rotatable connection between the baffle 4340 and the cavity wall (hereinafter referred to as the enclosure plate 2000) of the insulation cavity 2100, such as by riveting, which allows for rotation and also helps to achieve a covering and sealing effect.

[0131] Optionally, the drive shaft 4311 abuts against the rotation center of the baffle 4340. Since the baffle 4340 can rotate synchronously with the pin 4330, when the drive shaft 4311 abuts against the baffle 4340 and the drive shaft 4311 rotates, the rotation of the drive shaft 4311 and the baffle 4340 is synchronous. This not only drives the baffle 4340 to rotate, but also allows the baffle 4340 to be close to the cavity wall of the insulation cavity 2100 (the surrounding plate 2000 below), which is more conducive to achieving a covering seal on the basis of rotatability.

[0132] Optionally, combined Figure 14 As shown, in some embodiments, the drive mechanism 4300 further includes a mounting bracket 4350, which is connected to the cavity wall (hereinafter referred to as the enclosure 2000) of the insulation cavity 2100, and the motor 4310 is connected to the mounting bracket 4350. The bracket is configured to provide a foundation for mounting the motor 4310 and to allow a certain distance between the motor 4310 and the cavity wall (hereinafter referred to as the enclosure 2000) of the insulation cavity 2100, thereby reducing the heat transfer from the insulation cavity 2100 to the motor 4310.

[0133] Combination Figure 16 and Figure 17 As shown, in some embodiments, the cooking device further includes a first outlet 6100, which is connected to the cooking chamber 1100. Gas (including but not limited to steam, flue gas, etc.) in the cooking chamber 1100 can be discharged from the first outlet 6100. Optionally, the highest point of the first outlet 6100 is lower than the lowest point of the first smoke inlet 4110. Flue gas entering the cooking chamber 1100 from the first smoke inlet 4110 fills the cooking chamber 1100 from top to bottom and then exits from the first outlet 6100. By making the highest point of the first outlet 6100 lower than the lowest point of the first smoke inlet 4110, the flue gas is prevented from being quickly discharged from the first outlet 6100 after entering the cooking chamber 1100, which helps to make the flue gas evenly distributed in the cooking chamber 1100, thereby making the heat evenly distributed. It is understood that a similar effect is achieved when steam is introduced into the cooking chamber 1100, which will not be repeated here.

[0134] The cooking equipment also includes a second outlet 6200, which is connected to a heat preservation cavity 2100. Gas (including but not limited to flue gas) in the heat preservation cavity 2100 can be discharged from the second outlet 6200. By making the highest point of the second outlet 6200 lower than the lowest point of the second smoke inlet 4120, the flue gas entering the heat preservation cavity 2100 from the second smoke inlet 4120 fills the heat preservation cavity 2100 from top to bottom and then exits from the second outlet 6200. Before the flue gas fills the heat preservation cavity 2100, the cold air in the heat preservation cavity 2100 is gradually discharged through the second outlet 6200, which prevents the flue gas from entering the heat preservation cavity 2100 and being quickly discharged from the second outlet 6200. This helps to make the flue gas evenly distributed in the heat preservation cavity 2100 and achieve a better heat preservation effect.

[0135] Combination Figure 6 and Figure 17 As shown, in some embodiments, the cooking device also includes an exhaust channel 6300, with a first outlet 6100 connected to the exhaust channel 6300 and a second outlet 6200 connected to the exhaust channel 6300. That is, the first outlet 6100 and the second outlet 6200 share the exhaust channel 6300, which helps to simplify the structure.

[0136] Since the first outlet 6100 and the second outlet 6200 share the same exhaust channel 6300, under the premise that no smoke enters the insulation cavity 2100 and exits through the second outlet 6200, in order to prevent gas in the cooking cavity 1100 from entering the insulation cavity 2100 through the second outlet 6200 when it exits from the first outlet 6100, in this embodiment, combined with Figures 16 to 18 As shown, the cooking device also includes a one-way valve 7000, which is located at the second outlet 6200 to allow gas to flow unidirectionally from the heat preservation chamber 2100 toward the exhaust passage 6300.

[0137] For example, when fumes are introduced into the cooking chamber 1100 (gas path regulating device 4000 is in the first state), the fumes are discharged from the first outlet 6100. Due to the one-way valve 7000, the fumes discharged from the first outlet 6100 cannot enter the heat preservation chamber 2100 through the second outlet 6200, but are discharged along the exhaust channel 6300. When steam is introduced into the cooking chamber 1100 (gas path regulating device 4000 is in the second state), the steam is discharged from the first outlet 6100. Due to the one-way valve 7000, the steam discharged from the first outlet 6100 cannot enter the heat preservation chamber 2100 through the second outlet 6200, and the fumes are discharged from the second outlet 6200. Due to the steam pressure, the fumes discharged from the second outlet 6200 cannot enter the cooking chamber 1100 through the first outlet 6100, but are discharged along the exhaust channel 6300.

[0138] The structure of the 7000 check valve is as follows, combined with... Figures 16 to 18As shown, the one-way valve 7000 includes a sealing plate 7100, a support 7200, and an elastic element 7300. The second outlet 6200 has a first side 6210 facing the insulation cavity 2100 and a second side 6220 facing away from the insulation cavity 2100. The sealing plate 7100 is disposed on the second side 6220. The support 7200 is disposed on the sealing plate 7100 and extends from the sealing plate 7100 through the periphery of the second outlet 6200 to the first side 6210. The elastic element 7300 abuts against the end of the support 7200 exposed on the first side 6210 and between the periphery of the second outlet 6200. The elastic element 7300, such as a spring, causes the baffle 4340 to abut against the second side 6220, thereby closing the second outlet 6200. When the air pressure on the first side 6210 is greater than the air pressure on the second side 6220 and the force applied to the baffle 4340 is greater than the elastic force generated by the elastic element 7300, the baffle 4340 moves away from the second outlet 6200, thereby opening the second outlet 6200. Gas can be discharged from the insulation cavity 2100 through the second outlet 6200. When flue gas enters the insulation cavity 2100, the flue gas pressure in the insulation cavity 2100 increases, thereby pushing open the baffle 4340 to be discharged from the second outlet 6200. When the air pressure on the first side 6210 is less than the air pressure on the second side 6220 and the force applied to the baffle 4340 is less than the elastic force generated by the elastic member 7300, the baffle 4340 abuts against the second side 6220 to keep the second outlet 6200 closed. When steam enters the cooking chamber 1100 and exits from the first outlet 6100, it cannot enter the heat preservation chamber 2100 through the second outlet 6200.

[0139] Combination Figure 7 and Figure 8 As shown, in some embodiments, the cooking cavity 1100 and the heat preservation cavity 2100 are arranged with a common wall, which is more conducive to the heat preservation cavity 2100 providing heat preservation / auxiliary heating to the cooking cavity 1100. Optionally, the heat preservation cavity 2100 is located on the rear, left, and right sides of the cooking cavity 1100, so that the heat preservation cavity 2100 and the cooking cavity 1100 form a larger heat transfer area, which is more conducive to the heat preservation cavity 2100 providing heat preservation / auxiliary heating to the cooking cavity 1100.

[0140] Optionally, the cooking device includes an inner pot 1000 and a surrounding plate 2000. The inner pot 1000 has a cooking cavity 1100 inside. The surrounding plate 2000 is located outside the cooking cavity 1100 and together with the inner pot 1000, it encloses a heat preservation cavity 2100. The surrounding plate 2000 can be a single piece of board or composed of multiple (two or more) boards connected together. For example, the surrounding plate 2000 is a U-shaped plate, which is placed around the left, right and rear sides of the inner pot 1000 and together with the inner pot 1000, it encloses the heat preservation cavity 2100.

[0141] Combination Figure 2 , Figure 7 and Figure 8As shown, the inner liner 1000 has a mounting hole 1200 communicating with the cooking cavity 1100, the surrounding plate 2000 has an opening 2200, and the gas path regulating device 4000 is located between the mounting hole 1200 and the opening 2200. The opening 2200 is connected to the combustion device 3000 to allow the flue gas generated by the combustion device 3000 to flow out of the combustion device 3000. The gas path regulating device 4000 is adapted to control the flue gas generated by the combustion device 3000 to flow through the mounting hole 1200 to the cooking cavity 1100. With this arrangement, given that the heat preservation cavity 2100 is located outside the cooking cavity 1100, it is more advantageous for the cooking cavity 1100 and the heat preservation cavity 2100 to cooperate with the gas path regulating device 4000 respectively.

[0142] The combustion chamber 3200 of the combustion device 3000 is connected to the opening 2200. When the gas path regulating device 4000 is in the first state, since the first smoke inlet 4110 is open and the second smoke inlet 4120 is closed, the cooking chamber 1100, mounting hole 1200, first smoke inlet 4110, second concave cavity 4201, opening 2200, and combustion chamber 3200 are connected, and flue gas can flow to the cooking chamber 1100. When the gas path regulating device 4000 is in the second state, since the first smoke inlet 4110 is closed and the second smoke inlet 4120 is open, the heat preservation chamber 2100, second smoke inlet 4120, second concave cavity 4201, opening 2200, and combustion chamber 3200 are connected, and flue gas can flow to the heat preservation chamber 2100.
