Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a cooking device. Background Art

[0002] In the related art, for cooking devices with a steam heating function, after a water source injects water into a steam generating chamber, the water is heated into steam in the steam generating chamber. When the water in the steam generating chamber is dried up, the water source continues to inject water into the steam generating chamber. Currently, cooking devices generate steam at a slow speed, resulting in a long cooking time, and users need to wait a long time to complete cooking. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] In view of this, the present application provides a cooking device, which includes: a shell, a steam generating assembly and a valve assembly. A water supply pipeline is provided in the shell, the steam generating assembly is connected to the shell, and the steam generating assembly includes a steam generating chamber. The valve assembly is located in the shell, and a water outlet is provided on the valve assembly, the water outlet is located in the steam generating chamber, and the water supply pipeline is used to inject water into the steam generating chamber through the water outlet. When the valve assembly is in a first state, the water supply pipeline is connected to the water outlet, and when the valve assembly is in a second state, the valve assembly closes the water outlet.

[0005] In this technical solution, the steam generating assembly is connected to the shell, and the steam generating assembly is located inside the shell. The steam generating assembly includes a steam generating chamber, and the steam in the steam generating chamber can heat the food for cooking.

[0006] When the valve assembly is in the first state, the water supply pipeline is connected to the water outlet, so that the water in the water supply pipeline enters the steam generating chamber through the water outlet, thereby enabling the steam generating chamber to generate steam for heating the container. When the valve assembly is in the second state, the valve assembly closes the water outlet, and the water supply pipeline stops supplying water to the steam generating chamber.

[0007] In this way, the water supply pipeline between the valve assembly and the water source can always be in a water storage state. Since the water outlet is located in the steam generating chamber, when the valve assembly is opened, the time for water to circulate in the pipeline is saved, and water can flow directly from the water outlet into the steam generating chamber, thereby increasing the water inlet speed of the steam generating chamber, shortening the water inlet time of the steam generating chamber, and improving the steam generation efficiency. Steam can be generated quickly in the steam generating chamber, shortening the cooking time, and reducing the waiting time of the user during the cooking process, which is beneficial to improving the user experience of the cooking equipment.

[0008] In addition, the cooking device in the above embodiment provided by the present application may also have the following additional technical features:

[0009] In some technical solutions provided in the present application, optionally, the water outlets are distributed along the circumference of the valve assembly.

[0010] The water outlet is distributed circumferentially. When the water outlet discharges water into the steam generating chamber, the water enters the steam generating chamber in a circumferential spray manner. The water distribution in various parts of the steam generating chamber is relatively uniform, so that the water will not be too concentrated in a certain area. A small amount of water is distributed in various parts of the steam generating chamber. A small amount of water contacts with the high-temperature inner wall and can be quickly converted into steam, thereby increasing the steam generation rate.

[0011] In some technical solutions provided in the present application, optionally, the valve assembly is located in the steam generating chamber, and the valve assembly is spaced apart from the inner wall of the steam generating chamber.

[0012] In this technical solution, the valve assembly is spaced apart from any inner wall of the steam generating chamber so that there is a distance between the valve assembly and the side wall of the steam generating chamber, thereby reducing the obstruction of the water outlet of the valve assembly caused by the side wall, and placing the water outlet close to the center of the steam generating chamber. After the water falls into the center of the steam generating chamber, it diffuses to the surrounding areas, so that the water in various places in the steam generating chamber is evenly distributed, avoiding water accumulation caused by the side wall blocking the water outlet, making the steam generation effect of the steam generating assembly uniform, and steam can be generated simultaneously in various places in the steam generating chamber, thereby improving the steam generation efficiency.

[0013] In some technical solutions provided in the present application, optionally, a water guiding channel is provided on the valve assembly, the water guiding channel is connected to the water outlet, and the water guiding channel is distributed along the circumference of the water outlet.

[0014] In this technical solution, a water guide channel is provided on the valve assembly, and the water guide channel connects the water outlet and the steam generating chamber, so that the water discharged from the water outlet can enter the steam generating chamber through the water guide channel. The water guide channel is distributed along the circumference of the water outlet, that is, the water outlet is arranged at the center of the water guide channel, so that the water discharged from the water outlet can flow into the water guide channel evenly along the circumference, and then the water outlet can evenly discharge water to the periphery through the water guide channel, thereby expanding the water outlet range, allowing the water outlet to spread quickly and evenly, increasing the contact area between the water and the steam generating chamber, improving the uniformity and water outlet efficiency of the valve assembly, and improving the steam generation efficiency.

[0015] In some technical solutions provided in the present application, optionally, the valve assembly includes a nozzle, and the nozzle is provided with water outlets, and the water outlets are distributed along the circumference of the nozzle.

[0016] In this technical solution, the nozzle can increase the water outlet pressure of the valve assembly and expand the range of the water outlet position. The nozzle is provided with a water outlet, which is distributed along the circumference of the nozzle, so that the valve assembly can evenly discharge water along the periphery, so that the water outlet can be quickly and evenly spread, increasing the contact area between the water and the steam generation chamber, improving the uniformity and water outlet efficiency of the valve assembly, and improving the steam generation efficiency.

[0017] In some technical solutions provided in the present application, optionally, the water outlet is higher than the bottom wall of the steam generating chamber.

[0018] In this technical solution, the bottom wall of the steam generating chamber is usually provided with a heating component, so that the temperature of the bottom wall is relatively high, and the water outlet is higher than the bottom wall of the steam generating chamber, so that the water flowing out of the water outlet can directly fall on the bottom wall of the steam generating chamber under the action of gravity for heating, thereby improving the heating efficiency of the steam generating component, and thus improving the steam generation efficiency. In addition, a gap is formed between the water outlet and the bottom wall, which reduces the impact of the high temperature of the bottom wall on the valve component, avoids damage to the valve component due to high temperature, and thus avoids affecting the valve component controlling the opening and closing components of the water outlet.

[0019] In some technical solutions provided in the present application, optionally, the valve assembly includes a water storage chamber, the water outlet is arranged on the cavity wall of the water storage chamber, and the water supply pipeline is connected to the water storage chamber.

[0020] In this technical solution, the water outlet is arranged on the wall of the water storage chamber, specifically, the water outlet is arranged on the bottom wall of the water storage chamber. The water supply pipeline is connected with the water storage chamber, so that the water in the water supply pipeline can enter the water storage chamber through the water outlet, and the water in the water storage chamber can be discharged immediately after the outlet water is opened, which reduces the waiting time for water discharge and improves the water discharge efficiency of the water outlet.

[0021] In some technical solutions provided in the present application, optionally, the valve assembly includes a valve, the valve includes a movable part and a sealing part, the sealing part is connected to the end of the movable part, a part of the movable part extends into the water outlet, a gap is left between the inner wall of the water outlet and the movable part, the movable part can move relative to the water outlet, when the valve assembly is in a first state, the sealing part is separated from the water outlet, and when the valve assembly is in a second state, the sealing part covers the water outlet.

[0022] In this technical solution, the sealing part is connected to the end of the movable part, the sealing part is located above the movable part, at least a part of the movable part extends into the water outlet, and a gap is left between the inner wall of the water outlet and the movable part, so that water can flow out of the water outlet through the gap. In addition, the movable part is spaced from the inner wall of the water outlet so that the movable part can move relative to the water outlet, and when the movable part moves along the axial direction of the water outlet, a part of the movable part can extend out of or enter the water outlet.

[0023] The shape of the matching position of the sealing part and the water outlet is adapted to the shape of the water outlet. On the matching surface of the sealing part and the water outlet, the area of ​​the sealing part is larger than the area of ​​the water outlet, so that the sealing part can cover the water outlet. Exemplarily, the sealing part can be umbrella-shaped or cone-shaped. When the valve assembly is in the first state, the sealing part covers the water outlet, and the water supply pipeline stops supplying water to the steam generating chamber. When the valve assembly is in the second state, the sealing part is separated from the water outlet, and the water in the water supply pipeline can enter the steam generating chamber through the water outlet.

[0024] In this way, the gap between the movable part and the inner wall of the water outlet can ensure that water flows out of the water outlet smoothly, avoiding the movable part from hindering the movement of water flow, and the movable part can drive the sealing part to open or close the water outlet, ensuring the smoothness and accuracy of opening and closing the water outlet.

[0025] In some technical solutions provided in the present application, optionally, the valve further includes: a shell, a connecting portion and an elastic portion. The shell is connected to the steam generating assembly, the connecting portion is connected to the shell, the elastic portion is connected to the movable portion and the connecting portion, and the elastic portion is located between the connecting portion and the movable portion. The cooking device further includes a driving assembly, the driving assembly is connected to the steam generating assembly or the shell, and the driving assembly is used to drive the movable portion to move relative to the water outlet.

[0026] In this technical solution, the shell is connected to the steam generating assembly, and the connecting part is connected to the shell. For example, the connecting part and the shell can be connected by a connecting member, which can be a screw or a pin. Alternatively, the connecting part and the shell are respectively provided with a buckle and a slot structure, so that the connecting part is connected to the shell by a snap connection.

[0027] The driving assembly is connected to the steam generating assembly or the shell, and at least part of the driving assembly is located in the valve, so that the driving assembly can drive the movable part to move relative to the water outlet, and then the driving assembly can drive the sealing part to open or close the water outlet.

[0028] The elastic part is connected to the movable part and the connecting part, and the elastic part is located between the connecting part and the movable part. For example, the connecting part can be an annular structure, so that the connecting part is arranged around the outer periphery of the elastic part. Or the number of connecting parts can be multiple, and the multiple connecting parts are arranged around the outer periphery of the elastic part, and the multiple connecting parts are evenly distributed. When the movable part moves, the elastic part can provide a force to reset it, so that the movable part has a tendency to move in the reset direction.

[0029] In this way, the connecting part ensures the connection effect between the valve and the outer shell, the elastic part can provide a pulling force in the resetting direction to the movable part, thereby ensuring the resetting effect of the movable part, and the driving component realizes the control function of opening or closing the water outlet by driving the movable part to move, thereby improving the controllability and accuracy of the valve component in opening or closing the water outlet.

[0030] In some technical solutions provided in the present application, optionally, the steam generating assembly further includes a heating plate, and the heating plate is used to heat the water in the steam generating chamber. The driving assembly includes a temperature switch and a push rod assembly, and the temperature switch is connected to the heating plate. When the temperature of the heating plate reaches a set temperature, the temperature switch is in a first deformation state, and when the temperature of the heating plate is less than the set temperature, the temperature switch is in a second deformation state. The push rod assembly contacts the temperature switch, and the push rod assembly is used to push the movable part. In the first deformation state, the movable part is in a driving position so that the sealing part opens the water outlet, and in the second deformation state, the movable part is in an initial position.

[0031] In this technical solution, the heating plate is used to heat the water in the steam generating chamber. Exemplarily, the heating plate includes a plate body and a heating element, and the heating element can be a heating device such as a heating tube. The heating plate can heat the water to steam by increasing the temperature, and then the heating plate can heat the water in the steam generating chamber to generate steam. The heating plate is located at the bottom of the steam generating chamber, which is convenient for heating the water in the steam generating chamber.

[0032] The heating plate is located below the container, and there is a distance between the heating plate and the bottom wall of the container. The bottom wall and at least part of the side wall of the container are accommodated in the steam generating chamber. Due to the high temperature of the steam, the steam in the steam generating chamber can heat the container, thereby cooking the food in the container.

[0033] The temperature switch can be deformed according to its own temperature change. For example, the material of the temperature switch can be a temperature-sensitive material, such as a liquid crystal elastomer and a memory metal, or the temperature switch can be a bimetallic material synthesized by pressing two metals with different thermal expansion and contraction coefficients. The temperature switch is connected to the heating plate so that the temperature of the heating plate can be transmitted to the temperature switch. When the temperature of the heating plate reaches the set temperature, the temperature switch is in the first deformation state. When the temperature of the heating plate is lower than the set temperature, the temperature switch is in the second deformation state. The temperature switch can freely switch between the first deformation state and the second deformation state according to the temperature of the heating plate.

[0034] The push rod assembly is in contact with the temperature switch, one end of the push rod assembly is connected to the position where the temperature switch can be deformed, and the other end of the push rod assembly can be in contact with the movable part, so that the push rod assembly can push the movable part to move. Specifically, the temperature switch can be a circular plate or a strip plate, and the radial outer end portion of the temperature switch can be deformed under the influence of temperature, so that the radial outer end portion can change its axial position, even if the edge of the temperature switch can be flipped up and down, the end of the push rod assembly overlaps the edge of the temperature switch, so that the deformation of the temperature switch can change the axial position of the push rod assembly.

[0035] When the temperature switch is in the first deformation state, the push rod assembly is in the driving position, and the push rod assembly pushes the movable part so that the sealing part opens the water outlet, thereby allowing the water in the water supply pipeline to enter the steam generating chamber through the water outlet. When the temperature switch is in the second deformation state, the push rod assembly is in the initial position, and the sealing part seals the water outlet, thereby stopping the water in the water supply pipeline from entering the steam generating chamber.

[0036] When the cooking device is in working state, the heating plate is heated and heated up. When the temperature of the heating plate reaches the set temperature, the valve assembly opens the water outlet to connect the water outlet with the steam generating chamber, and the water in the water supply line enters the steam generating chamber through the water outlet. In this case, the heating plate is in a hot state with a relatively high temperature, and the water enters the steam generating chamber and is quickly evaporated by the heat to form steam. At the same time, the temperature of the heating plate is gradually reduced through heat exchange of the liquid water in the steam generating chamber. When the temperature of the heating plate is lower than the set temperature, the valve assembly closes the water outlet, so that the water outlet is in the second state, and the water in the water supply line stops entering the steam generating chamber. In this case, the heating plate can continue to heat up until the temperature of the heating plate reaches the set temperature again, and the water control assembly opens the water outlet again, and the above process is repeated.

[0037] In this way, the valve assembly can open or close the water outlet according to the temperature of the heating plate, so that the valve assembly can control the connection state between the water outlet and the steam generating chamber, and then the cooking device controls the water supply pipeline and the water inlet state in the steam generating chamber through the temperature of the heating plate. In addition, the valve assembly ensures that a certain amount of water enters the steam generating chamber, and the heating plate heats the certain amount of water, which reduces the time of steam generation, increases the speed of steam generation by the heating plate, and increases the steam generation efficiency in the steam generating chamber.

[0038] Moreover, the present application can also solve the problem of the speed of water valve response in the related art, because after water is poured in, the thermistor will be activated and the valve will be closed. Water can no longer enter, and water can only be added after it is boiled dry. In the present solution, after the water flows out, especially under the premise of having multiple water outlets, a small amount of water contacts the high-temperature inner wall and can quickly turn into steam. The temperature of the heating plate does not drop so obviously, and water can continue to enter. Even if the valve assembly is closed, there is not so much water in the steam generating chamber, and the valve assembly can be activated again more quickly, thereby extending the time for the valve assembly to enter water and the time for each steam generation. At the same time, the action of the valve assembly can be accelerated and steam can be generated quickly.

[0039] In some technical solutions provided in the present application, optionally, the temperature is set to T, and T satisfies 100°C<T<150°C.

[0040] When the preset temperature is within the above range, the steam generating assembly can achieve dry burning to a certain extent, and the valve assembly can ensure that a certain amount of water enters the steam generating chamber, and the heating plate heats the certain amount of water, thereby reducing the steam generation time and increasing the speed at which the heating plate generates steam.

[0041] In some technical solutions provided in the present application, optionally, the cooking device further comprises a water tank. The water tank is connected to the housing, and a water outlet of the water tank is connected to a water supply pipeline.

[0042] In this technical solution, the water tank can accommodate water for delivery to the steam generating assembly, and the water outlet of the water tank is connected to the water supply pipeline, so that the water stored in the water tank can enter the water supply pipeline, and the water tank realizes the water storage function. The water tank is connected to the shell, so that the shell provides structural support for the water tank. Exemplarily, the water tank is detachably connected to the shell, which is convenient for installation and replacement of the water tank, and water storage operation after the water tank is removed.

[0043] In some technical solutions provided in the present application, optionally, taking the bottom wall of the shell as a reference plane, the drain outlet of the water tank is higher than the water storage chamber.

[0044] The drain outlet of the water tank is higher than the water storage chamber, so that after the water in the water tank flows out of the water tank, it can flow directly to the water storage chamber under the action of gravity, reducing auxiliary components such as water pumps, saving components required for water supply, and simplifying the product structure.

[0045] In some technical solutions provided in the present application, optionally, taking the bottom wall of the shell as a reference plane, the drain port of the water tank is higher than the water outlet.

[0046] The drain port of the water tank is higher than the water outlet, so that the water in the water tank can flow directly to the water outlet under the action of gravity after flowing out of the water tank, reducing auxiliary components such as water pumps, saving components required for water supply, and simplifying the product structure.

DETAILED DESCRIPTION

[0060] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0061] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0062] Refer to the following Figures 1 to 9 A cooking device 10 according to some embodiments of the present application is described.

[0063] The embodiment of the present application provides a cooking device 10, such as Figure 1 As shown, the cooking device 10 includes: a housing 100, a steam generating assembly 300 and a valve assembly 400. A water supply pipeline 110 is provided in the housing 100, the steam generating assembly 300 is connected to the housing 100, and the steam generating assembly 300 includes a steam generating chamber 310. The valve assembly 400 is located in the housing 100, and a water outlet 410 is provided on the valve assembly 400, and the water outlet 410 is located in the steam generating chamber 310. The water supply pipeline 110 is used to inject water into the steam generating chamber 310 through the water outlet 410. When the valve assembly 400 is in a first state, the water supply pipeline 110 is connected to the water outlet 410. When the valve assembly 400 is in a second state, the valve assembly 400 closes the water outlet 410.

[0064] In this embodiment, the steam generating assembly 300 is connected to the housing 100. The steam generating assembly 300 is located inside the housing 100. The steam generating assembly 300 includes a steam generating chamber 310. The steam in the steam generating chamber 310 can heat food materials for cooking.

[0065] When the valve assembly 400 is in the first state, the water supply pipeline 110 is connected to the water outlet 410, so that the water in the water supply pipeline 110 enters the steam generating chamber 310 through the water outlet 410, thereby enabling steam to be generated in the steam generating chamber 310. When the valve assembly 400 is in the second state, the valve assembly 400 closes the water outlet 410, and the water supply pipeline 110 stops supplying water to the steam generating chamber 310.

[0066] In this way, the water supply pipe 110 between the valve assembly 400 and the water source can always be in a water storage state. Since the water outlet 410 is located in the steam generating chamber 310, when the valve assembly 400 is opened, the time for water to circulate in the pipe is saved, and water can flow directly from the water outlet 410 into the steam generating chamber, thereby increasing the water inlet speed of the steam generating chamber 310, shortening the water inlet time of the steam generating chamber 310, and improving the steam generation efficiency. Steam can be quickly generated in the steam generating chamber 310, shortening the cooking time, and reducing the waiting time of the user during the cooking process, which is beneficial to improving the user experience of the cooking equipment.

[0067] In a possible application, the cooking device further includes: a container 200, and the steam generated by the steam generating chamber 310 is used to heat the container 200. In other embodiments, a steam waiting heating component may also be provided on the housing 100.

[0068] In some embodiments provided in the present application, optionally, the water outlet 410 is arranged along the circumference of the valve assembly 400 ( Figure 8 The arrow at c in the figure points to the distribution.

[0069] The water outlet 410 is distributed circumferentially. When the water outlet 410 discharges water into the steam generating chamber 310, water enters the steam generating chamber 310 in a circumferential spray manner. The water distribution in various parts of the steam generating chamber 310 is relatively uniform, so that the water will not be too concentrated in a certain area. A small amount of water is distributed in various parts of the steam generating chamber 310. The small amount of water contacts the high-temperature inner wall and can be quickly converted into steam, thereby increasing the steam generation rate.

[0070] Exemplarily, the first state refers to the valve assembly 400 being in an open state, and the second state refers to the valve assembly 400 being in a closed state.

[0071] In some embodiments provided in this application, Figure 2 and Figure 3 As shown, optionally, the valve assembly 400 is located in the steam generating chamber 310 , and the valve assembly 400 is spaced apart from the inner wall of the steam generating chamber 310 .

[0072] In this embodiment, the valve assembly 400 is spaced apart from any inner wall of the steam generating chamber 310 so that there is a distance between the valve assembly 400 and the side wall of the steam generating chamber 310, thereby reducing the obstruction of the water outlet of the valve assembly 400 caused by the side wall, and the water outlet 410 is close to the center of the steam generating chamber 310. After the water falls into the center of the steam generating chamber 310, it diffuses to the surroundings, so that the water volume in various places in the steam generating chamber 310 is evenly distributed, and the side wall blocking the water outlet and causing water flow accumulation is avoided, so that the steam generating assembly 300 can generate steam evenly, and steam can be generated simultaneously in various places in the steam generating chamber 310, thereby improving the steam generation efficiency.

[0073] Exemplarily, the valve assembly 400 is equidistant from any inner sidewall of the steam generating chamber 310 , that is, the valve assembly 400 is located at the center of the steam generating chamber 310 .

[0074] Of course, in other embodiments, the valve assembly 400 may also be installed outside the steam generating chamber 310 , and only the water outlet 410 may be arranged inside the steam generating chamber 310 .

[0075] In some embodiments provided in this application, Figure 4 and Figure 8 As shown, optionally, a water guiding channel 420 is provided on the valve assembly 400 , the water guiding channel 420 is connected to the water outlet 410 , and the water guiding channel 420 is distributed along the circumference of the water outlet 410 .

[0076] In this embodiment, a water guide channel 420 is provided on the valve assembly 400, and the water guide channel 420 connects the water outlet 410 and the steam generating chamber 310, so that the water discharged from the water outlet 410 can enter the steam generating chamber 310 through the water guide channel 420. The water guide channel 420 is distributed along the circumference of the water outlet 410, that is, the water outlet 410 is arranged at the center of the water guide channel 420, so that the water discharged from the water outlet 410 can flow into the water guide channel 420 uniformly along the circumference, and then the water outlet 410 can evenly discharge water to the periphery through the water guide channel 420, thereby expanding the water discharge range, allowing the water to be quickly and evenly spread, increasing the contact area between the water and the steam generating chamber 310, improving the uniformity and water discharge efficiency of the valve assembly 400, and improving the steam generation efficiency.

[0077] For example, the outer wall of the water channel 420 is provided with a drain port, the number of which may be one, and the shape of the drain port is annular. Alternatively, the number of the drain ports may be multiple, and the multiple annular drain ports are arranged at intervals to improve the water discharge efficiency of the water channel 420. Alternatively, the multiple drain ports are distributed in the circumference of the outer wall, and the multiple drain ports are evenly distributed along the circumference.

[0078] In some embodiments provided in this application, Fig. 9 As shown, optionally, the valve assembly 400 includes a nozzle 430 , and the nozzle 430 is provided with water outlets 410 , and the water outlets 410 are distributed along the circumference of the nozzle 430 .

[0079] In this embodiment, the nozzle 430 can increase the water outlet pressure of the valve assembly 400 and expand the range of the water outlet position. The nozzle 430 is provided with a water outlet 410, and the water outlet 410 is distributed along the circumference of the nozzle 430, so that the valve assembly 400 can evenly discharge water along the periphery, so that the water outlet can be quickly and evenly spread, increasing the contact area between the water and the steam generating chamber 310, improving the uniformity and water outlet efficiency of the valve assembly 400, and improving the steam generation efficiency.

[0080] For example, the number of the water outlet 410 may be one, and the shape of the water outlet 410 is annular. Alternatively, the number of the water outlet 410 may be multiple, and multiple annular water outlets 410 are arranged at intervals to improve the water outlet efficiency of the valve assembly 400. Alternatively, the multiple water outlets 410 are distributed in the circumference of the valve assembly 400, and the multiple water outlets 410 are evenly distributed along the circumference.

[0081] In some embodiments provided in this application, Figure 2 and Figure 3 As shown, optionally, the water outlet 410 is higher than the bottom wall of the steam generating chamber 310 .

[0082] In this embodiment, the bottom wall of the steam generating chamber 310 is usually provided with a heating component, so that the temperature of the bottom wall is relatively high, and the water outlet 410 is higher than the bottom wall of the steam generating chamber 310, so that the water flowing out of the water outlet 410 can directly fall on the bottom wall of the steam generating chamber 310 under the action of gravity to be heated, thereby improving the heating efficiency of the steam generating assembly 300, and further improving the steam generation efficiency. In addition, a gap is formed between the water outlet 410 and the bottom wall, which reduces the impact of the high temperature of the bottom wall on the valve assembly 400, avoids the valve assembly 400 from being damaged by the high temperature, and thus avoids affecting the valve assembly 400 to control the opening and closing components of the water outlet 410.

[0083] In some embodiments provided in this application, Figure 2 and Figure 3 As shown, optionally, the valve assembly 400 includes a water storage chamber 440 , the water outlet 410 is disposed on the chamber wall of the water storage chamber 440 , and the water supply pipeline 110 is connected to the water storage chamber 440 .

[0084] In this embodiment, the water outlet 410 is disposed on the cavity wall of the water storage cavity 440, specifically, the water outlet 410 is disposed on the bottom wall of the water storage cavity 440. The water supply pipeline 110 is connected with the water storage cavity 440, so that the water in the water supply pipeline 110 can enter the water storage cavity 440 through the water outlet 410, and the water in the water storage cavity 440 can be discharged immediately after the outlet water is turned on, thereby reducing the waiting time for water discharge and improving the water discharge efficiency of the water outlet 410.

[0085] In some embodiments provided in this application, Figure 4 As shown, optionally, the valve assembly 400 includes a valve 450, and the valve 450 includes a movable part 451 and a sealing part 452. The sealing part 452 is connected to the end of the movable part 451, and a part of the movable part 451 extends into the water outlet 410. A gap is left between the inner wall of the water outlet 410 and the movable part 451, and the movable part 451 can move relative to the water outlet 410. When the valve assembly 400 is in a first state, the sealing part 452 is separated from the water outlet 410, and when the valve assembly 400 is in a second state, the sealing part 452 covers the water outlet 410.

[0086] In this embodiment, the sealing portion 452 is connected to the end of the movable portion 451, the sealing portion 452 is located above the movable portion 451, at least a portion of the movable portion 451 extends into the water outlet 410, and a gap is left between the inner wall of the water outlet 410 and the movable portion 451, so that water can flow out of the water outlet 410 through the gap. In addition, the movable portion 451 is spaced from the inner wall of the water outlet 410, so that the movable portion 451 can move relative to the water outlet 410, and when the movable portion 451 moves along the axial direction of the water outlet 410, a portion of the movable portion 451 can extend out of or enter the water outlet 410.

[0087] The shape of the matching position of the sealing portion 452 and the water outlet 410 is adapted to the shape of the water outlet 410. On the matching surface of the sealing portion 452 and the water outlet 410, the area of ​​the sealing portion 452 is larger than the area of ​​the water outlet 410, so that the sealing portion 452 can cover the water outlet 410. Exemplarily, the sealing portion 452 can be umbrella-shaped or cone-shaped. When the valve assembly 400 is in the first state, the sealing portion 452 covers the water outlet 410, and the water supply pipeline 110 stops conveying water to the steam generating chamber 310. When the valve assembly 400 is in the second state, the sealing portion 452 is separated from the water outlet 410, and the water in the water supply pipeline 110 can enter the steam generating chamber 310 through the water outlet 410.

[0088] For example, the sealing part 452 is made of elastic material, such as rubber or silicone material. The elastic part is soft, so the elastic part can fit tightly with the housing 100, thereby effectively sealing the water outlet 410 and optimizing the closing effect of the water control component on the water outlet 410.

[0089] In this way, the gap between the movable part 451 and the inner wall of the water outlet 410 can ensure that water flows out of the water outlet 410 smoothly, avoiding the movable part 451 from hindering the movement of water flow, and the movable part 451 can drive the sealing part 452 to open or close the water outlet 410, ensuring the smoothness and accuracy of opening and closing of the water outlet 410.

[0090] In some embodiments provided in this application, Figure 4 As shown, optionally, the valve 450 further includes: a housing 455, a connecting portion 453 and an elastic portion 454. The housing 455 is connected to the steam generating assembly 300, the connecting portion 453 is connected to the housing 455, the elastic portion 454 is connected to the movable portion 451 and the connecting portion 453, and the elastic portion 454 is located between the connecting portion 453 and the movable portion 451. The cooking device 10 further includes a driving assembly 500, which is connected to the steam generating assembly 300 or the housing 100, and is used to drive the movable portion 451 to move relative to the water outlet 410.

[0091] In this embodiment, the housing 455 is connected to the steam generating assembly 300, and the connecting portion 453 is connected to the housing 455. For example, the connecting portion 453 and the housing 455 can be connected by a connecting member, which can be a screw or a pin. Alternatively, the connecting portion 453 and the housing 455 are respectively provided with a buckle and a slot structure, so that the connecting portion 453 is connected to the housing 455 by a snap connection.

[0092] The driving assembly 500 is connected to the steam generating assembly 300 or the shell 100 , and at least part of the driving assembly 500 is located in the valve 450 , so that the driving assembly 500 can drive the movable part 451 to move relative to the water outlet 410 , and then the driving assembly 500 can drive the sealing part 452 to open or close the water outlet 410 .

[0093] The elastic part 454 is connected to the movable part 451 and the connecting part 453, and the elastic part 454 is located between the connecting part 453 and the movable part 451. For example, the connecting part 453 may be an annular structure, so that the connecting part 453 is arranged around the outer periphery of the elastic part 454. Alternatively, the number of the connecting parts 453 may be multiple, and multiple connecting parts 453 are arranged around the outer periphery of the elastic part 454, and the multiple connecting parts 453 are evenly distributed. When the movable part 451 moves, the elastic part 454 can provide a force to reset it, so that the movable part 451 has a tendency to move in the reset direction.

[0094] Specifically, a portion of the elastic portion 454 is bent in a direction away from the driving assembly 500. The bending direction is beneficial for the elastic portion 454 to provide a pulling force toward the driving assembly 500 to the movable portion 451 when it is deformed, so that the movable portion 451 has a tendency to drive the sealing portion 452 to move in the direction of the sealed water outlet 410.

[0095] In this way, the connecting part 453 ensures the connection effect between the valve 450 and the shell 455, the elastic part 454 can provide a pulling force in the resetting direction to the movable part 451, thereby ensuring the resetting effect of the movable part 451, and the driving component 500 realizes the control function of opening or closing the water outlet 410 by driving the movable part 451 to move, thereby improving the controllability and accuracy of the valve component 400 in opening or closing the water outlet 410.

[0096] In some embodiments provided in this application, Figure 2 and Figure 3 As shown, optionally, the steam generating assembly 300 further includes a heating plate 320, and the heating plate 320 is used to heat the water in the steam generating chamber 310. The driving assembly 500 includes a temperature switch 510 and a push rod assembly 520, and the temperature switch 510 is connected to the heating plate 320. When the temperature of the heating plate 320 reaches the set temperature, the temperature switch 510 is in a first deformation state, and when the temperature of the heating plate 320 is less than the set temperature, the temperature switch 510 is in a second deformation state. The push rod assembly 520 contacts the temperature switch 510, and the push rod assembly 520 is used to push the movable part 451. In the first deformation state, the movable part 451 is in the driving position so that the sealing part 452 opens the water outlet 410, and in the second deformation state, the movable part 451 is in the initial position.

[0097] In this embodiment, the heating plate 320 is used to heat the water in the steam generating chamber 310. Exemplarily, the heating plate 320 includes a plate body and a heating element, and the heating element can be a heating device such as a heating tube. The heating plate 320 can heat the water to steam by increasing the temperature, so that the heating plate 320 can heat the water in the steam generating chamber 310 to generate steam. The heating plate 320 is located at the bottom of the steam generating chamber 310, so as to heat the water in the steam generating chamber 310.

[0098] The heating plate 320 is located below the container 200, and a distance is provided between the heating plate 320 and the bottom wall of the container 200. The bottom wall and at least a portion of the side wall of the container 200 are accommodated in the steam generating chamber 310. Since the temperature of the steam is relatively high, the steam in the steam generating chamber 310 can heat the container 200, thereby cooking the food in the container 200.

[0099] The temperature switch 510 can be deformed according to its own temperature change. For example, the material of the temperature switch 510 can be a temperature-sensitive material, such as a liquid crystal elastomer and a memory metal, or the temperature switch 510 uses a bimetallic material that is pressed and synthesized by two metals with different thermal expansion and contraction coefficients. The temperature switch 510 is connected to the heating plate 320 so that the temperature of the heating plate 320 can be transmitted to the temperature switch 510. When the temperature of the heating plate 320 reaches the set temperature, the temperature switch 510 is in a first deformation state. When the temperature of the heating plate 320 is less than the set temperature, the temperature switch 510 is in a second deformation state. The temperature switch 510 can freely switch between the first deformation state and the second deformation state according to the temperature of the heating plate 320.

[0100] The push rod assembly 520 is in contact with the temperature switch 510, one end of the push rod assembly 520 is connected to the position where the temperature switch 510 can be deformed, and the other end of the push rod assembly 520 can be in contact with the movable part 451, so that the push rod assembly 520 can push the movable part 451 to move. Specifically, the temperature switch 510 can be a circular plate or a strip plate, and the radial outer end portion of the temperature switch 510 can be deformed under the influence of temperature, so that the radial outer end portion can change its axial position, even if the edge of the temperature switch 510 can be flipped up and down, the end of the push rod assembly 520 overlaps the edge of the temperature switch 510, so that the deformation of the temperature switch 510 can change the axial position of the push rod assembly 520.

[0101] When the temperature switch 510 is in the first deformation state, the push rod assembly 520 is in the driving position, and the push rod assembly 520 pushes the movable part 451 to make the sealing part 452 open the water outlet 410, thereby allowing the water in the water supply pipeline 110 to enter the steam generating chamber 310 through the water outlet 410. When the temperature switch 510 is in the second deformation state, the push rod assembly 520 is in the initial position, and the sealing part 452 seals the water outlet 410, thereby stopping the water in the water supply pipeline 110 from entering the steam generating chamber 310.

[0102] When the cooking device 10 is in the working state, the heating plate 320 is heated and heated. When the temperature of the heating plate 320 reaches the set temperature, the valve assembly 400 opens the water outlet 410 so that the water outlet 410 is connected to the steam generating chamber 310, and the water in the water supply pipeline 110 enters the steam generating chamber 310 through the water outlet 410. In this case, the heating plate 320 is in a hot state with a relatively high temperature, and the water enters the steam generating chamber 310 and evaporates rapidly to form steam. At the same time, the temperature of the heating plate 320 is gradually reduced by heat exchange of liquid water in the steam generating chamber 310. When the temperature of the heating plate 320 is lower than the set temperature, the valve assembly 400 closes the water outlet 410, so that the water outlet 410 is in the second state, and the water in the water supply pipeline 110 stops entering the steam generating chamber 310. In this case, the heating plate 320 can continue to heat up until the temperature of the heating plate 320 reaches the set temperature again, and the water control assembly opens the water outlet 410 again, and the above process is repeated.

[0103] In this way, the valve assembly 400 can open or close the water outlet 410 according to the temperature of the heating plate 320, so that the valve assembly 400 can control the communication state between the water outlet 410 and the steam generating chamber 310, and then the cooking device 10 controls the water supply pipeline 110 and the water inlet state in the steam generating chamber 310 through the temperature of the heating plate 320. In addition, the valve assembly 400 ensures that a certain amount of water enters the steam generating chamber 310, and the heating plate 320 heats the certain amount of water, which reduces the time of steam generation, increases the speed of steam generation by the heating plate 320, and increases the steam generation efficiency in the steam generating chamber 310.

[0104] Moreover, the present application can also solve the problem of the speed of water valve response in the related art, because after water is poured in, the thermistor will be activated and the valve will be closed. Water can no longer enter, and water can only be added after it is boiled dry. In the present solution, after the water flows out, especially under the premise of having multiple water outlets 410, a small amount of water contacts the high-temperature inner wall and can quickly turn into steam. The temperature of the heating plate 320 does not drop so obviously, and water can continue to enter. Even if the valve assembly 400 is closed, there is not so much water in the steam generating chamber 310, and the valve assembly 400 can be activated again more quickly, thereby extending the time for the valve assembly 400 to enter water and the time for each steam generation. At the same time, the action of the valve assembly 400 can be accelerated and steam can be generated quickly.

[0105] In some technical solutions provided in the present application, optionally, the temperature is set to T, and T satisfies 100°C<T<150°C.

[0106] When the preset temperature is within the above range, the steam generating assembly 300 can achieve dry burning to a certain extent, and the valve assembly can ensure that a certain amount of water enters the steam generating chamber 310, and the heating plate 320 heats the certain amount of water, thereby reducing the time for steam generation and increasing the speed at which the heating plate generates steam.

[0107] Exemplarily, the set temperature T may be 100°C, 120°C or 150°C.

[0108] In some embodiments provided in this application, Figure 5 , Figure 6 and Figure 7 As shown, optionally, the push rod assembly 520 includes: a paddle 530 and a push rod. The paddle 530 contacts the temperature switch 510, and the temperature switch 510 is used to push the paddle 530. One end of the push rod contacts the paddle 530, and the paddle 530 is used to push the push rod, and the push rod is used to push the elastic member.

[0109] In this embodiment, the paddle 530 contacts the temperature switch 510, and the paddle 530 overlaps the position where the temperature switch 510 can be deformed. The temperature switch 510 is used to push the paddle 530. When the temperature switch 510 is deformed, the paddle 530 can move following the deformation of the temperature switch 510.

[0110] One end of the top rod contacts the paddle 530, and the other end of the top rod contacts the elastic member. Exemplarily, the paddle 530 may be a strip plate, and the two ends of the paddle 530 are respectively connected to the temperature switch 510 and the top plate, so that the paddle 530 can push the top rod to move when following the movement of the temperature switch 510, and then the top rod can push the elastic member to move, so as to open or close the water outlet 410, and then control the connection state between the water supply end and the steam generating chamber 310.

[0111] like Figure 6 As shown, when the temperature of the heating plate 320 is lower than the set temperature, the temperature switch 510 is in the second deformation state, and the outer edge of the temperature switch 510 extends downwardly. Figure 7 As shown, when the temperature of the heating plate 320 reaches the set temperature, the temperature switch 510 is in the first deformation state, the outer edge of the temperature switch 510 extends upwardly tilted, and the paddle 530 is lifted by the outer edge of the temperature switch 510, thereby causing the paddle 530 to move upward driven by the temperature switch 510.

[0112] In this way, the paddle 530 extends the distance between the temperature switch 510 and the top rod, thereby extending the position of the heating plate 320 relative to the top rod and the water outlet 410, expanding the position range of the water supply end, and facilitating the reasonable layout of the internal structure of the cooking device 10. In addition, the paddle 530 transmits the deformation of the temperature switch 510 to the top rod, reducing the size of the temperature switch 510 and reducing the production cost of the temperature switch 510.

[0113] In some embodiments provided in the present application, optionally, the temperature switch 510 is fitted with the heating plate 320. Or the cooking device 10 further includes a heat conducting member, and the heat of the heating plate 320 is transferred to the temperature switch 510 through the heat conducting member.

[0114] In this embodiment, the temperature switch 510 fits the heating plate 320 , so that the temperature of the heating plate 320 is directly transmitted to the temperature switch 510 , thereby improving the transmission efficiency and accuracy of the temperature of the heating plate 320 .

[0115] The cooking device 10 also includes a heat conductor, through which the heat of the heating plate 320 is transferred to the temperature switch 510, thereby extending the distance between the heating plate 320 and the temperature switch 510, expanding the position range of the temperature switch 510, and facilitating the reasonable layout of the position of the temperature switch 510.

[0116] In some embodiments provided in this application, Figure 1 As shown, optionally, the cooking device 10 further includes a water tank 600 . The water tank 600 is connected to the housing 100 , and the water outlet 410 of the water tank 600 is connected to the water supply pipeline 110 .

[0117] In this embodiment, the water tank 600 can accommodate water for delivery to the steam generating assembly 300, and the water outlet 410 of the water tank 600 is connected to the water supply pipeline 110, so that the water stored in the water tank 600 can enter the water supply pipeline 110, and the water tank 600 realizes the water storage function. The water tank 600 is connected to the housing 100, so that the housing 100 provides structural support for the water tank 600. Exemplarily, the water tank 600 is detachably connected to the housing 100, which is convenient for the installation and replacement of the water tank 600, and the water storage operation after the water tank 600 is removed.

[0118] In some technical solutions provided in the present application, optionally, with the bottom wall of the shell 100 as a reference plane, the drain outlet of the water tank 600 is higher than the water storage chamber 440 .

[0119] The drain outlet of the water tank 600 is higher than the water storage chamber 440, so that after the water in the water tank 600 flows out of the water tank 600, it can flow directly to the water storage chamber 440 under the action of gravity, reducing auxiliary components such as water pumps, saving components required for water supply, and simplifying the product structure.

[0120] In some technical solutions provided in the present application, optionally, taking the bottom wall of the shell 100 as a reference plane, the drain port of the water tank 600 is higher than the water outlet 410 .

[0121] The drain outlet of the water tank 600 is higher than the water outlet 410, so that after the water in the water tank 600 flows out of the water tank 600, it can flow directly to the water outlet 410 under the action of gravity, reducing auxiliary components such as water pumps, saving components required for water supply, and simplifying the product structure.

[0122] In a possible embodiment, the cooking device 10 may be a steam stew pot, which is mainly composed of a water supply pipeline 110, a valve assembly 400, and a steam generating assembly 300, and its main features are: the valve assembly 400 has a switch structure that can respond to temperature changes (a switch in a broad sense that can control the water inlet and outlet of the water supply pipeline 110 due to temperature changes).

[0123] The valve assembly 400 has a water storage chamber 440, a water channel 420, a water outlet 410, a temperature switch 510 and an elastic part 454; the main feature of the water outlet 410 is that it can discharge water circumferentially, and the circumferential water outlet 410 is approximately located at the center of the steam generation area of ​​the steam generation assembly 300. The water storage chamber 440 has a certain water storage function, and the temperature switch 510 is a structure that can respond to temperature changes. When the temperature is lower than the set value, the temperature switch 510 does not change, and the water in the water storage chamber 440 cannot enter the steam generation chamber 310. When the temperature is higher than the set value, the temperature switch 510 deforms, and the deformation is transmitted to the elastic part 454 through the driving assembly 500. The deformation of the elastic part 454 causes the water in the water storage chamber 440 to flow evenly into the steam generation chamber 310 through the circumferential water outlet 410.

[0124] Working principle: When the steam generating assembly 300 is working, the heating plate 320 is heated and the temperature is transmitted to the temperature switch 510. The temperature switch 510 is deformed and changes the state of the valve assembly 400 from closed to open. Water flows from the water storage chamber 440 to the steam generating chamber 310 through the circumferential water outlet 410. At this time, the heating plate 320 is in a hot state. After the water enters, it is quickly evaporated by the heat to produce steam. At the same time, after the liquid water enters the steam generating chamber 310, the temperature of the heating plate 320 is reduced due to heat exchange. After the temperature of the heating plate 320 is reduced, the temperature switch 510 will be closed, and the valve assembly 400 will be further closed, ensuring that only a certain amount of water enters the steam generating chamber 310, thereby improving the steam generation efficiency. The heating plate 320 continues to heat, and after a certain amount of water is completely converted into steam, the heating plate 320 starts to heat up again, the temperature switch 510 opens, the valve assembly 400, and the water enters the steam generating chamber 310 again, and the above process is repeated. Only an appropriate amount of water is heated each time to quickly produce steam. The water inlet is controlled by the temperature change of the heating plate 320, and the circumferential water discharge makes the steam more evenly distributed.
