[0027] An embodiment of the present application provides a cooking device, which can be a steamer, a steam oven, or any device with cooking function and water supply requirement, without limitation. The cooking device comprises an inner container and a water inlet assembly. The inner container is provided with a cooking cavity for placing and cooking food materials, and the cooking cavity will have temperature changes when cooking food materials. The water inlet assembly is provided with a water inlet channel communicated with the cooking cavity to supply water to the cooking cavity, thereby meeting the cooking requirement of the food materials. Optionally, the water inlet assembly further comprises a water source, which can be a water source outside the cooking device or a water tank provided by the cooking device. The water inlet channel is communicated with the water source and the cooking cavity to make the water flow from the water source into the cooking cavity through the water inlet channel.

[0028] Referring to Figure 1 , Figure 1This diagram shows a perspective view of the on / off device 100 in one embodiment of the present application. The water inlet assembly includes the on / off device 100 located on the path of the water inlet channel. The on / off device 100 is connected to the inner liner and located on one side of the cooking cavity. Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 A cross-sectional schematic diagram of an on / off device 100 according to an embodiment of this application is shown. The on / off device 100 includes a housing 110 with an internal receiving cavity 111 and a partition 120 located inside the receiving cavity 111. The housing 110 is made of a heat-conducting material. Since the on / off device 100 is located on one side of the cooking cavity, when food is cooked in the cooking cavity, the temperature inside the cooking cavity will rise, and the heat conduction of the housing 110 will cause the temperature inside the receiving cavity 111 to rise accordingly. The partition 120 divides the receiving cavity 111 into a sealed cavity 1111 and a water-passing cavity 1112. The sealed cavity 1111 is a sealed space. When the temperature of the housing 110 and the sealed cavity 1111 rises, the gas inside the sealed cavity 1111 will expand due to heat, increasing the pressure inside the sealed cavity 1111, thereby pushing the partition 120 to move. The water passage 1112 is part of the water inlet channel for water to flow through. The baffle 120 is movably connected to the housing 110 to open or close the water passage 1112. When the baffle 120 opens or closes the water passage 1112, the water inlet channel is opened or closed.

[0029] like Figures 1 to 3 As shown, in one embodiment, the housing 110 has an inlet 112 and an outlet 113 on different end faces. Both the inlet 112 and the outlet 113 are connected to the receiving cavity 111, and the outlet 113 is opened on the bottom surface 115 of the housing 110, so that the height of the inlet 112 opened on the other end face is higher than that of the outlet 113 opened on the bottom surface 115, so that the water flows to the outlet 113 under the action of gravity, without the need for a water pump to control the direction of the water flow.

[0030] In one embodiment, the water inlet 112 is located on the top surface 114 of the housing 110. In other embodiments, the water inlet 112 may also be located on the side of the housing 110, provided that the height of the water inlet 112 is higher than the height of the water outlet 113, and this is not a limitation.

[0031] In one embodiment, the inlet 112 and the outlet 113 correspond to different positions on the movement path of the partition 120, and the outlet 113 is closer to the partition 120 than the inlet 112. In one embodiment, when the partition 120 is located as follows... Figure 3When the position indicated by the dotted line is between the water outlet 113 and the water inlet 112, the partition 120 can effectively isolate the connection between the water outlet 113 and the water inlet 112, preventing water from entering the water outlet 113 and thus preventing it from flowing into the cooking cavity. This achieves the effect of the partition 120 moving to disconnect the water passage 1112. The moving distance of the partition 120 can be calculated based on the initial volume and initial air pressure of the sealed cavity 1111, combined with the temperature changes in the cooking cavity and the force required for the partition 120 to move. Therefore, by setting different initial volumes of the sealed cavity 1111 and the force required for the partition 120 to move, the moving distance of the partition 120 during cooking can be controlled, ensuring that it moves as expected during cooking. Figure 3 The dotted line shown in the figure stops precisely between the outlet 113 and the inlet 112, thus isolating the connection between the outlet 113 and the inlet 112.

[0032] like Figures 1 to 3 As shown, in one embodiment, the housing 110 includes a limiting block 130 protruding toward the interior of the receiving cavity 111. The limiting block 130 is located on the moving path of the partition 120 and on the side of the partition 120 toward the sealed cavity 1111, so as to avoid the partition 120 moving too far to compress the space of the sealed cavity 1111, resulting in insufficient airflow in the sealed cavity 1111, and to prevent the air pressure change in the sealed cavity 1111 from being insufficient to push the partition 120 to move a specific distance when the temperature inside the cooking cavity changes.

[0033] like Figures 1 to 3 As shown, in one embodiment, the on / off device 100 includes an elastic element 140. One end of the elastic element 140 is connected to the partition 120, and the other end is connected to the housing 110. The elastic element 140 has a tendency to move the partition 120 toward the compression sealed cavity 1111, so that after cooking, when the temperature in the cooking cavity drops, the temperature and pressure in the sealed cavity 1111 also drop. At this time, the elastic element 140 drives the partition 120 to reset. In this embodiment, the elastic element 140 drives the partition 120 to reset to abut against the limiting block 130. In this embodiment, the elastic element 140 is a spring; in other embodiments, the elastic element 140 may also be an elastic rope, etc.

[0034] like Figures 1 to 3 As shown, in one embodiment, the elastic element 140 is located within the water passage cavity 1112, and the end of the elastic element 140 away from the partition 120 is connected to the end face of the housing 110 away from the sealed cavity 1111. In other embodiments, the elastic element 140 may also be located within the sealed cavity 1111, and the end of the elastic element 140 away from the partition 120 is connected to the end face of the housing 110 away from the water passage cavity 1112.

[0035] In one embodiment, the on-off device 100 further comprises a trigger connected to the housing 110 and located inside the accommodating cavity 111, the trigger is located on the moving path of the partition 120 and configured to be triggered when the partition 120 contacts the trigger, to indicate that the partition 120 moves to the position of the trigger. In this embodiment, the trigger is a sensing bar code. Exemplarily, in this embodiment, the trigger is arranged on the inner wall of the housing 110 and faces the water outlet 113. In other embodiments, the trigger can also be arranged at other positions.

[0036] In one embodiment, the on-off device 100 further comprises a closure connected to the housing 110 and facing the water inlet 112, and the closure is configured to be able to open and close the water inlet 112. When the closure closes the water inlet 112, the water flow cannot flow into the water passage cavity 1112 through the water inlet 112, and when the closure is opened, the water flow can enter the water passage cavity 1112 through the water inlet 112.

[0037] In one embodiment, the closure is communicatively connected to be controlled by the trigger, and the closure is configured to close the water inlet 112 when the trigger is triggered. In this embodiment, the closure is also controlled by the switch signal of the cooking device. When the cooking device starts the steaming program, the closure is automatically opened, and at this time the water flow can enter the water passage cavity 1112 through the water inlet 112. When the trigger is triggered, the closure is closed and blocks the water inlet 112. In other embodiments, the closure can also be arranged to be able to automatically open under the gravity of the water flow itself, and close to block the water inlet 112 when the trigger is triggered, for example, a rotating baffle structure.

[0038] In the cooking device provided in the above scheme, when the cooking device is used to steam food, when the cooking device starts the steaming function, the closing member is opened, at this time, water flows from the water source into the water passage 1112 through the water inlet 112, and then enters the cooking cavity through the water outlet 113. As the cooking device enters the preheating state, the heating disc of the cooking device starts to work, and the temperature inside the cooking cavity rises to 100℃. Since the on-off device 100 is located on one side of the cooking cavity and the shell 110 is made of heat-conducting material, as the temperature in the cooking cavity continues to rise, the heat in the cooking cavity will be conducted to the shell 110 and the containing cavity 111, and since the closed cavity 1111 is a closed space, the temperature continues to rise, the gas in the closed cavity 1111 continues to expand and the pressure increases, and when the pressure of the closed cavity 1111 exceeds the force of the elastic member 140 on the partition plate 120, the partition plate 120 will be pushed to move towards the direction of the water inlet 112 to compress the elastic member 140. During the movement, the partition plate 120 passes through the trigger member and triggers the trigger member, at this time the trigger member releases an electrical signal, the closing member is closed to block the water inlet 112, and the water flow stops entering the cooking cavity. When the cooking is completed, the temperature in the cooking cavity continues to decrease, and due to the elastic force of the elastic member 140 and the decrease of the temperature in the closed cavity 1111, the internal pressure decreases, so that the partition plate 120 is reset to the position abutting against the limiting block 130.

[0039] In the cooking device provided in the above scheme, by arranging the on-off device 100 on one side of the cooking cavity in the water inlet channel, and arranging the closed cavity 1111 and the partition plate 120 on one side of the closed cavity 1111 inside the on-off device 100, when the cooking cavity starts to cook food, as the temperature in the cooking cavity continues to rise, the heat in the cooking cavity will be conducted to the shell 110 and the containing cavity 111, and since the closed cavity 1111 is a closed space, the temperature continues to rise, the gas in the closed cavity 1111 continues to expand and the pressure increases, thereby pushing the partition plate 120 to move, realizing the on-off of the water passage 1112 on the other side of the partition plate 120, and realizing the on-off of the whole water inlet channel, which realizes the control of the on-off of the water passage 1112 by absorbing the heat of the cooking cavity, so that the water inlet channel directly supplies water to the cooking cavity during the start and preheating of the cooking device, but stops water supply after the preheating of the cooking device is completed, so that it automatically adjusts the on-off according to the working state of the cooking device. Compared with the control mode of water pump and electromagnetic valve in the prior art, the structure is simple and the cost is lower.

[0040] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0041] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
