Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a cooking equipment. Background Art

[0002] In the related art, for cooking equipment with steam heating function, water from a water source flows into the steam generating chamber through a water inlet pipe. After the water is injected, a portion of water will remain in the water inlet pipe. This portion of water will breed bacteria if it remains in the water inlet pipe for a long time, causing the steam generating chamber to be contaminated when water is injected next time. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, the utility model proposes a cooking device, comprising: a shell; a water supply pipeline, which is arranged on the shell; a steam generating component, the steam generating component comprising a steam generating chamber and a heating plate, the heating plate being used to heat water in the steam generating chamber to generate steam; a water control component, which is located in the shell, and is used to open or close the passage between the water supply pipeline and the steam generating chamber; a waste water pipeline, which is arranged on the shell, and one end of the waste water pipeline is connected to the water supply pipeline; and a valve body, which is used to switch the waste water pipeline between a passage state and a cut-off state.

[0005] The steam generating assembly includes a heating plate and a steam generating chamber. Exemplarily, the heating plate includes a plate body and a heating element. The heating element may be a heating device such as a heating tube. The heating plate can heat the water to steam by increasing the temperature, thereby enabling the heating plate to heat the water in the steam generating chamber to generate steam. When the water control assembly opens the passage between the water supply pipeline and the steam generating chamber, the water at the water supply end enters the steam generating chamber. When the water control assembly closes the passage between the water supply pipeline and the steam generating chamber, the water at the water supply end stops entering the steam generating chamber.

[0006] When the water injection into the steam generating chamber stops, some water will remain in the water supply pipeline, and this water can be discharged to the outside through the wastewater pipeline. Specifically, the wastewater pipeline is connected to the water supply pipeline, and when it is not necessary to discharge the water in the water supply pipeline, the valve body closes the wastewater pipeline. When it is necessary to discharge the residual water in the water supply pipeline, the wastewater pipeline is opened through the valve body, and the water in the water supply pipeline flows out along the wastewater pipeline, thereby emptying the residual water in the water supply pipeline, avoiding the long-term residual water accumulation in the water supply pipeline, keeping the water supply pipeline in a dry state, avoiding the growth of bacteria in the water supply pipeline, and ensuring the cleanliness of the water injected into the steam generating chamber.

[0007] Moreover, when the user needs to clean the water supply pipeline, the user can also close the passage between the water supply pipeline and the steam generating chamber through the water control component, and then open the waste water pipeline, so that the water supply pipeline can be cleaned by injecting water into the water supply pipeline.

[0008] In addition, the cooking device in the above technical solution provided by the utility model may also have the following additional technical features:

[0009] In some technical solutions, optionally, the valve body is connected to the shell and can move relative to the shell. When the valve body is in a first position, the wastewater pipeline is in a passage state. When the valve body is in a second position, the valve body squeezes the wastewater pipeline to put the wastewater pipeline in a cut-off state.

[0010] The valve body can move relative to the shell. When the valve body is in the first position, the valve body is separated from the wastewater pipeline, or the valve body and the wastewater pipeline just fit together. At this time, the channel in the wastewater pipeline is in an open state, and the water in the water supply pipeline can be discharged through the wastewater pipeline. When the valve body is in the second position, the valve body squeezes the wastewater pipeline. At this time, the channel in the wastewater pipeline is in a closed state, and the water in the water supply pipeline cannot be discharged through the wastewater pipeline. The user can manually drive the valve body to open or close the wastewater pipeline. The structure of the valve body is simple and easy to implement.

[0011] In some technical solutions, optionally, when the valve body is in an open state, the wastewater pipeline is in a passage state, and when the valve body is in a closed state, the wastewater pipeline is in a cut-off state.

[0012] A valve body can be installed on the wastewater pipeline. When the valve body is in the open state, the wastewater pipeline is in the open state, and the water in the water supply pipeline can be discharged through the wastewater pipeline. When the valve body is in the closed state, the wastewater pipeline is in the cut-off state, and the water in the water supply pipeline cannot be discharged through the wastewater pipeline. The valve body can be a manual valve body or an electric valve body. The valve body can improve the sealing of the wastewater pipeline when it is cut off, and avoid water leakage in the water supply pipeline.

[0013] In some technical solutions, optionally, from one end of the wastewater pipeline to the other end of the wastewater pipeline, at least a portion of the wastewater pipeline is inclined toward the bottom wall of the shell.

[0014] One end of the wastewater pipe is connected to the water supply pipe, and the wastewater pipe is inclined toward the bottom wall of the shell. Therefore, from one end of the wastewater pipe to the other end of the wastewater pipe, the height of the wastewater pipe gradually decreases compared to the bottom wall of the shell. When the wastewater pipe is in an open state, water can be discharged along the wastewater pipe under the action of gravity, thereby improving the smoothness of water discharge and avoiding the problem of water accumulation in the wastewater pipe.

[0015] In some technical solutions, optionally, the cooking device further includes: a waste water box connected to the shell, and the other end of the waste water pipeline is connected to the waste water box.

[0016] A waste water box is installed on the shell. When the water in the water supply pipe is discharged, the water flows into the waste water box along the waste water pipe. The waste water box can collect the accumulated water. When there is no pool or other place near the cooking equipment, the accumulated water can be prevented from remaining outside the shell of the cooking equipment, saving the user the workload of cleaning the external drainage of the cooking equipment, which is conducive to improving the user experience of the cooking equipment.

[0017] In some technical solutions, optionally, a water inlet is provided on the shell. When the temperature of the heating plate reaches a set temperature, the water control component opens the water inlet to connect the water inlet with the steam generating chamber. When the temperature of the heating plate is lower than the set temperature, the water control component closes the water inlet.

[0018] The water control component is connected to the shell. When the cooking device is in working state, the heating plate is heated and heated. When the temperature of the heating plate reaches the set temperature, the water control component opens the water inlet to connect the water inlet with the steam generating chamber, and the water at the water supply end enters the steam generating chamber through the water inlet. In this case, the heating plate is in a hot state with a relatively high temperature. 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 liquid water in the steam generating chamber. When the temperature of the heating plate is lower than the set temperature, the water control component closes the water inlet, so that the water inlet is in a closed state, and the liquid at the water supply end 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. The water control component opens the water inlet again and repeats the above process.

[0019] In this way, the water control component can open or close the water inlet according to the temperature of the heating plate, so that the water control component can control the connection state between the water inlet and the steam generating chamber, and then the cooking device controls the water supply end and the water inlet state in the steam generating chamber through the temperature of the heating plate. The cooking device can realize the automatic water inlet function, avoid the user manually opening or closing the water inlet, reduce the risk of the heating plate drying for a long time, and improve the convenience and safety of the water supply of the cooking device. In addition, the water control component can ensure 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 improves the steam generation efficiency in the steam generating chamber.

[0020] In some technical solutions, optionally, the temperature is set to T, where T satisfies 100°C<T<150°C.

[0021] When the preset temperature is within the above range, the steam generating component can achieve dry burning to a certain extent, and the water control component can ensure that a certain amount of water enters the steam generating chamber. The heating plate heats the certain amount of water, which reduces the steam generation time and increases the speed at which the heating plate generates steam.

[0022] In some technical schemes, optionally, the water control component includes: a valve component, connected to the shell, the valve component is used to open or close the water inlet; a drive component, connected to the shell, when the temperature of the heating plate reaches the set temperature, the drive component is used to push the valve component, the valve component is deformed and opens the water inlet, when the temperature of the heating plate is lower than the set temperature, the valve component closes the water inlet.

[0023] The driving assembly is connected to the heating plate. When the temperature of the heating plate does not reach the set temperature, the driving assembly can be against the valve assembly, or a distance can be set between the driving assembly and the valve assembly. When the temperature of the heating plate reaches the set temperature, the driving assembly moves toward the valve assembly, so that the driving assembly can push the valve assembly, and the valve assembly opens the water inlet, so that the water inlet is connected to the steam generating chamber, and the water at the water supply end enters the steam generating chamber through the water inlet. When the temperature of the heating plate is lower than the set temperature, the valve assembly closes the water inlet, so that the water inlet is in a closed state relative to the steam generating chamber, and the liquid at the water supply end stops entering the steam generating chamber.

[0024] In this way, the deformation state of the valve assembly is controlled by the movement of the driving assembly, so that the valve assembly can open or close the water inlet. The control method is direct and the structure is flexible, which facilitates the installation of the water control assembly and the maintenance and replacement in subsequent use.

[0025] In a possible application, the valve component includes an elastic rubber component or an elastic silicone component.

[0026] The valve assembly is an elastic part, and the valve assembly is relatively soft, so the valve assembly can fit tightly with the housing, thereby being able to effectively seal the water inlet, and optimizing the closing effect of the water control assembly on the water inlet. When the driving assembly stops driving the valve assembly, the valve assembly can automatically reset under the action of elasticity to seal the water inlet.

[0027] In some technical schemes, optionally, the driving assembly includes: a temperature switch, which is connected to the shell, and when the temperature of the heating plate reaches the set temperature, the temperature switch is in a first deformation state, and when the temperature of the heating plate is lower than the set temperature, the temperature switch is in a second deformation state; a push rod assembly, which is in contact with the temperature switch, and the push rod assembly is used to push the valve assembly, and when the temperature switch is in the first deformation state, the push rod assembly is in a driving position to enable the valve assembly to open the water inlet, and when the temperature switch is in the second deformation state, the push rod assembly is in an initial position.

[0028] The temperature switch can deform 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.

[0029] 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 a first deformation state. When the temperature of the heating plate is lower than the set temperature, the temperature switch is in a 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.

[0030] 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 valve assembly, so that the push rod assembly pushes the valve assembly to deform. 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.

[0031] 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 valve assembly to open the water inlet, thereby allowing the water at the water supply end to enter the steam generating chamber through the water inlet. When the temperature switch is in the second deformation state, the push rod assembly is in the initial position, and the valve assembly seals the water inlet, thereby stopping the liquid at the water supply end from entering the steam generating chamber.

[0032] In this way, the push rod assembly controls the deformation of the valve assembly through the deformation of the temperature switch, and then controls the opening and closing state of the water inlet. The control method is simple and direct, and the control effect is flexible and accurate, which improves the flexibility and accuracy of the driving assembly in opening and closing the water inlet.

[0033] In some technical schemes, optionally, the push rod assembly includes: a paddle, which contacts the temperature switch, and the temperature switch is used to push the paddle; a push rod, one end of the push rod is in contact with the paddle, and the other end of the push rod is in contact with the valve assembly, the paddle is used to push the push rod, and the push rod is used to push the valve assembly.

[0034] The paddle is in contact with the temperature switch, and the paddle is overlapped at a position where the temperature switch can be deformed. The temperature switch is used to push the paddle. When the temperature switch is deformed, the paddle can move following the deformation of the temperature switch.

[0035] One end of the push rod contacts the paddle, and the other end of the push rod contacts the valve assembly. For example, the paddle can be a strip plate, and the two ends of the paddle are respectively connected to the temperature switch and the top plate, so that the paddle can push the push rod to move when following the movement of the temperature switch, and then the push rod can push the valve assembly to move, so as to open or close the water inlet, thereby controlling the connection state between the water supply end and the steam generating chamber.

[0036] In this way, the paddle extends the distance between the temperature switch and the top rod, thereby extending the position of the heating plate relative to the top rod and the water inlet, expanding the position range of the water supply end, and facilitating the reasonable layout of the internal structure of the cooking device. In addition, the paddle transmits the deformation of the temperature switch to the top rod, reducing the size of the temperature switch and reducing the production cost of the temperature switch.

[0037] In some technical solutions, optionally, the cooking device further includes: a water tank connected to the shell, and a water supply pipeline connected to a water outlet of the water tank.

[0038] The water tank can hold water for delivery to the steam generating assembly, that is, the water tank realizes the water storage function of the water supply end. 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.

[0039] One end of the water supply pipeline is connected to the water tank, and the other two ends of the water supply pipeline are connected to the water inlet, so that the water tank and the water inlet are connected through the water supply pipeline, which extends the distance between the water tank and the water inlet, expands the position range of the water tank, and facilitates the reasonable layout of the water tank.

DETAILED DESCRIPTION

[0054] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model 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.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0056] Refer to the following Figures 1 to 10 The cooking device provided according to some embodiments of the present invention is described.

[0057] Combination Figure 1 and Figure 2As shown, in an embodiment of the utility model, a cooking device is proposed, comprising: a housing 100, a water supply pipeline 200, a steam generating assembly 400, a water control assembly 500, a waste water pipeline 600 and a valve body 700. The water supply pipeline 200 is arranged on the housing 100. The steam generating assembly 400 is connected to the housing 100, and the steam generating assembly 400 comprises a steam generating chamber 410 and a heating plate 420, and the heating plate 420 is used to heat the water in the steam generating chamber 410 to generate steam. The water control assembly 500 is located in the housing 100, and the water control assembly 500 is used to open or close the passage between the water supply pipeline 200 and the steam generating chamber 410, and when the water inlet 110 is in an open state, the water inlet 110 is connected to the steam generating chamber 410. The wastewater pipeline 600 is disposed on the housing 100 , one end of the wastewater pipeline 600 is connected to the water supply pipeline 200 , and the valve body 700 is used to switch the wastewater pipeline 600 between a passage state and a cutoff state.

[0058] The steam generating assembly 400 includes a heating plate 420 and a steam generating chamber 410. For example, the heating plate 420 includes a plate body and a heating element. The heating element can be a heating device such as a heating tube. The heating plate 420 can heat the water to steam by increasing the temperature, so that the heating plate 420 can heat the water in the steam generating chamber 410 to generate steam. When the water control assembly 500 opens the passage between the water supply pipeline 200 and the steam generating chamber 410, the water at the water supply end enters the steam generating chamber 410. When the water control assembly 500 closes the passage between the water supply pipeline 200 and the steam generating chamber 410, the water at the water supply end stops entering the steam generating chamber 410.

[0059] When the water injection into the steam generating chamber 410 is stopped, a part of water will remain in the water supply pipe 200, and the part of water can be discharged outward through the waste water pipe 600. Specifically, the waste water pipe 600 is connected with the water supply pipe 200, and when the water in the water supply pipe 200 does not need to be discharged, the valve body 700 closes the waste water pipe 600. When the residual water in the water supply pipe 200 needs to be discharged, the waste water pipe 600 is opened through the valve body 700, and the water in the water supply pipe 200 flows out along the waste water pipe 600, thereby emptying the residual water in the water supply pipe 200, avoiding the water accumulation in the water supply pipe 200 for a long time, keeping the water supply pipe 200 in a dry state, avoiding the growth of bacteria in the water supply pipe 200, and ensuring the cleanliness of the water injected into the steam generating chamber 410.

[0060] Moreover, when the user needs to clean the water supply pipeline 200, the user can also close the passage between the water supply pipeline 200 and the steam generating chamber 410 through the water control component 500, and then open the waste water pipeline 600, so that the water supply pipeline 200 can be cleaned by injecting water into the water supply pipeline 200.

[0061] In a possible application, the water supply pipeline 200 and the wastewater pipeline 600 may be pipeline structures independently installed on the housing 100 , or the water supply pipeline 200 and the wastewater pipeline 600 may be structures formed based on the housing 100 .

[0062] In a possible application, the cooking device further comprises a container 300, and the steam generated in the steam generating chamber 410 is used to heat the container. Alternatively, in other embodiments, a steamer waiting for heating component may be arranged on the housing 100.

[0063] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the valve body 700 is connected to the shell 100, and the valve body 700 can move relative to the shell 100. When the valve body 700 is in a first position, the wastewater pipe 600 is in a passage state. When the valve body 700 is in a second position, the valve body 700 squeezes the wastewater pipe 600 so that the wastewater pipe 600 is in a cut-off state.

[0064] The valve body 700 can move relative to the housing 100. When the valve body 700 is in the first position, the valve body 700 is separated from the wastewater pipeline 600, or the valve body 700 is just fitted with the wastewater pipeline 600. At this time, the channel in the wastewater pipeline 600 is in an open state, and the water in the water supply pipeline 200 can be discharged through the wastewater pipeline 600. When the valve body 700 is in the second position, the valve body 700 squeezes the wastewater pipeline 600. At this time, the channel in the wastewater pipeline 600 is in a closed state, and the water in the water supply pipeline 200 cannot be discharged through the wastewater pipeline 600. The user can manually drive the valve body 700 to open or close the wastewater pipeline 600. The structure of the valve body 700 is simple and easy to implement.

[0065] In some embodiments, optionally, when the valve body 700 is in an open state, the wastewater pipeline 600 is in a passage state, and when the valve body 700 is in a closed state, the wastewater pipeline 600 is in a cut-off state.

[0066] A valve body 700 may be installed on the wastewater pipeline 600, and the valve body 700 can be opened or closed. When the valve body 700 is in the open state, the wastewater pipeline 600 is in a passage state, and the water in the water supply pipeline 200 can be discharged through the wastewater pipeline 600. When the valve body 700 is in the closed state, the wastewater pipeline 600 is in a cut-off state, and the water in the water supply pipeline 200 cannot be discharged through the wastewater pipeline 600. The valve body 700 may be a manual valve or an electric valve, and the valve body 700 may improve the sealing of the wastewater pipeline 600 when it is cut off, thereby avoiding water leakage in the water supply pipeline 200.

[0067] In some embodiments, optionally, from one end of the wastewater pipe 600 to the other end of the wastewater pipe 600 , at least a portion of the wastewater pipe 600 is inclined toward the bottom wall of the shell 100 .

[0068] One end of the wastewater pipe 600 is connected to the water supply pipe 200, and the wastewater pipe 600 is inclined toward the bottom wall of the shell 100. Therefore, from one end of the wastewater pipe 600 to the other end of the wastewater pipe 600, the height of the wastewater pipe 600 gradually decreases compared to the bottom wall of the shell 100. When the wastewater pipe 600 is in an open state, the water flow can be discharged along the wastewater pipe 600 under the action of gravity, thereby improving the smoothness of the water flow during discharge and avoiding the problem of water storage in the wastewater pipe 600.

[0069] In some embodiments, optionally, the cooking device further includes: a waste water box 800 , the waste water box 800 is connected to the housing 100 , and the other end of the waste water pipe 600 is connected to the waste water box 800 .

[0070] A waste water box 800 is installed on the shell 100. When the water in the water supply pipe 200 is discharged, the water flows into the waste water box 800 along the waste water pipe 600. The waste water box 800 can collect the accumulated water. When there is no pool or other place near the cooking equipment, the accumulated water can be prevented from remaining outside the cooking equipment shell 100, which saves the user the cleaning workload of draining the outside of the cooking equipment, and is conducive to improving the user's experience of using the cooking equipment.

[0071] In a possible application, the waste water box 800 can be pulled out of the housing 100 , so that the waste water box 800 can be pulled out of the housing 100 , so as to facilitate dumping of the accumulated water in the waste water box 800 .

[0072] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, a water inlet 110 is provided on the housing 100. When the temperature of the heating plate 420 reaches a set temperature, the water control component 500 opens the water inlet 110 to connect the water inlet 110 with the steam generating chamber 410. When the temperature of the heating plate 420 is lower than the set temperature, the water control component 500 closes the water inlet 110 ( Figure 6 The dotted line in the middle indicates the direction of water flow).

[0073] The water control component 500 is connected to the housing 100. When the cooking device is in working state, the heating plate 420 is heated and heated. When the temperature of the heating plate 420 reaches the set temperature, the water control component 500 opens the water inlet 110 so that the water inlet 110 is connected with the steam generating chamber 410, and the water at the water supply end enters the steam generating chamber 410 through the water inlet 110. In this case, the heating plate 420 is in a hot state with a relatively high temperature, and the water enters the steam generating chamber 410 and evaporates rapidly to form steam. At the same time, the liquid water gradually reduces the temperature of the heating plate 420 through heat exchange in the steam generating chamber 410. When the temperature of the heating plate 420 is lower than the set temperature, the water control component 500 closes the water inlet 110, so that the water inlet 110 is in a closed state, and the liquid at the water supply end stops entering the steam generating chamber 410. In this case, the heating plate 420 can continue to heat up until the temperature of the heating plate 420 reaches the set temperature again, and the water control component 500 opens the water inlet 110 again, and repeats the above process.

[0074] In this way, the water control component 500 can open or close the water inlet 110 according to the temperature of the heating plate 420, so that the water control component 500 can control the connection state between the water inlet 110 and the steam generating chamber 410, and then the cooking device controls the water supply end and the water inlet state in the steam generating chamber 410 through the temperature of the heating plate 420. The cooking device realizes the automatic water inlet function, avoids the user manually opening or closing the water inlet 110, reduces the risk of the heating plate 420 burning dry for a long time, and improves the convenience and safety of the water supply of the cooking device. In addition, the water control component 500 can ensure that a certain amount of water enters the steam generating chamber 410, and the heating plate 420 heats the certain amount of water, which reduces the time of steam generation, increases the speed of steam generation by the heating plate 420, and improves the steam generation efficiency in the steam generating chamber 410.

[0075] When the water inlet 110 is opened, the passage between the water supply pipeline 200 and the steam generating chamber 410 is opened, and when the water inlet 110 is closed, the passage between the water supply pipeline 200 and the steam generating chamber 410 is closed.

[0076] In some technical solutions, optionally, the temperature is set to T, where T satisfies 100°C<T<150°C.

[0077] When the preset temperature is within the above range, the steam generating component 400 can achieve dry burning to a certain extent, and the water control component 500 can ensure that a certain amount of water enters the steam generating chamber 410, and the heating plate 420 heats the certain amount of water, thereby reducing the steam generation time and increasing the speed at which the heating plate 420 generates steam.

[0078] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, optionally, a water inlet 110 is provided on the housing 100, and the water control assembly 500 includes: a valve assembly 510 and a drive assembly 520, wherein the valve assembly 510 is connected to the housing 100, and the valve assembly 510 is used to open or close the water inlet 110. The drive assembly 520 is connected to the housing 100, and when the temperature of the heating plate 420 reaches the set temperature, the drive assembly 520 is used to push the valve assembly 510, and the valve assembly 510 is deformed and opens the water inlet 110, and when the temperature of the heating plate 420 is lower than the set temperature, the valve assembly 510 is reset and closes the water inlet 110.

[0079] The valve assembly 510 is connected to the housing 100 . The valve assembly 510 is disposed at the water inlet 110 . The valve assembly 510 can generate elastic deformation to open or close the water inlet 110 .

[0080] The driving assembly 520 is connected to the heating disk 420. When the temperature of the heating disk 420 does not reach the set temperature, the driving assembly 520 can be against the valve assembly 510, or a distance can be set between the driving assembly 520 and the valve assembly 510. When the temperature of the heating disk 420 reaches the set temperature, the driving assembly 520 moves toward the valve assembly 510, so that the driving assembly 520 can push the valve assembly 510, and the valve assembly 510 deforms and opens the water inlet 110, so that the water inlet 110 is connected to the steam generating chamber 410, and the water at the water supply end enters the steam generating chamber 410 through the water inlet 110. When the temperature of the heating disk 420 is lower than the set temperature, the valve assembly 510 resets and closes the water inlet 110, so that the water inlet 110 is in a closed state relative to the steam generating chamber 410, and the liquid at the water supply end stops entering the steam generating chamber 410.

[0081] In this way, the deformation state of the valve assembly 510 is controlled by the movement of the driving assembly 520, so that the valve assembly 510 can open or close the water inlet 110. The control method is direct and the structure is flexible, which facilitates the installation of the water control assembly 500 and the maintenance and replacement in subsequent use.

[0082] In a possible application, a water inlet pipeline 120 is disposed between the water inlet 110 and the steam generating chamber 410 , and the water inlet pipeline 120 is used to connect the water inlet 110 and the steam generating chamber 410 .

[0083] In some embodiments, the valve assembly 510 may include a rubber elastic member or a silicone elastic member. The valve assembly 510 has a stable and highly elastic elastic effect, and the valve assembly 510 is easy to deform. A small driving force can deform the valve assembly 510, thereby improving the triggering flexibility. The valve assembly 510 can form a large elastic deformation, expand the deformation range of the valve assembly 510, optimize the reset effect of the valve assembly 510, and thus improve the flexibility and accuracy of the valve assembly 510 in opening and closing the water inlet 110.

[0084] Combination Figure 3 , Figure 7 , Fig. 9 and Fig.10 As shown, in some embodiments, optionally, the driving assembly 520 includes: a temperature switch 521 and a push rod assembly 522. The temperature switch 521 is connected to the housing 100. When the temperature of the heating plate 420 reaches the set temperature, the temperature switch 521 is in a first deformation state. When the temperature of the heating plate 420 is less than the set temperature, the temperature switch 521 is in a second deformation state. The push rod assembly 522 is in contact with the temperature switch 521. The push rod assembly 522 is used to push the valve assembly 510. When the temperature switch 521 is in the first deformation state, the push rod assembly 522 is in a driving position to enable the valve assembly 510 to open the water inlet 110. When the temperature switch 521 is in the second deformation state, the push rod assembly 522 is in an initial position.

[0085] The temperature switch 521 can be deformed according to its own temperature change. Exemplarily, the material of the temperature switch 521 can be a temperature-sensitive material, such as a liquid crystal elastomer and a memory metal, or the temperature switch 521 uses a bimetallic material synthesized by pressing two metals with different thermal expansion and contraction coefficients.

[0086] The temperature switch 521 is connected to the heating disk 420 so that the temperature of the heating disk 420 can be transmitted to the temperature switch 521. When the temperature of the heating disk 420 reaches the set temperature, the temperature switch 521 is in the first deformation state. When the temperature of the heating disk 420 is lower than the set temperature, the temperature switch 521 is in the second deformation state. The temperature switch 521 can freely switch between the first deformation state and the second deformation state according to the temperature of the heating disk 420.

[0087] The push rod assembly 522 is in contact with the temperature switch 521, one end of the push rod assembly 522 is connected to the position where the temperature switch 521 can be deformed, and the other end of the push rod assembly 522 can be in contact with the valve assembly 510, so that the push rod assembly 522 pushes the valve assembly 510 to deform. Specifically, the temperature switch 521 can be a circular plate or a strip plate, and the radial outer end portion of the temperature switch 521 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 521 can be flipped up and down, the end of the push rod assembly 522 overlaps the edge of the temperature switch 521, so that the deformation of the temperature switch 521 can change the axial position of the push rod assembly 522.

[0088] When the temperature switch 521 is in the first deformation state, the push rod assembly 522 is in the driving position, and the push rod assembly 522 pushes the valve assembly 510, so that the valve assembly 510 opens the water inlet 110, thereby allowing the water at the water supply end to enter the steam generating chamber 410 through the water inlet 110. When the temperature switch 521 is in the second deformation state, the push rod assembly 522 is in the initial position, and the valve assembly 510 seals the water inlet 110, thereby stopping the liquid at the water supply end from entering the steam generating chamber 410.

[0089] In this way, the push rod assembly 522 controls the deformation of the valve assembly 510 through the deformation of the temperature switch 521, and then controls the opening and closing state of the water inlet 110. The control method is simple and direct, and the control effect is flexible and accurate, which improves the flexibility and accuracy of the driving assembly 520 to open and close the water inlet 110.

[0090] Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, the push rod assembly 522 includes: a paddle 523 and a push rod 524, the paddle 523 contacts the temperature switch 521, the temperature switch 521 is used to push the paddle 523, one end of the push rod 524 contacts the paddle 523, the other end of the push rod 524 contacts the valve assembly 510, the paddle 523 is used to push the push rod 524, and the push rod 524 is used to push the valve assembly 510.

[0091] The paddle 523 contacts the temperature switch 521 , and the paddle 523 overlaps the position where the temperature switch 521 can be deformed. The temperature switch 521 is used to push the paddle 523 . When the temperature switch 521 is deformed, the paddle 523 can move following the deformation of the temperature switch 521 .

[0092] One end of the push rod 524 contacts the paddle 523, and the other end of the push rod 524 contacts the valve assembly 510. Exemplarily, the paddle 523 may be a strip plate, and the two ends of the paddle 523 are respectively connected to the temperature switch 521 and the top plate, so that the paddle 523 can push the push rod 524 to move when following the movement of the temperature switch 521, and then the push rod 524 can push the valve assembly 510 to move, so as to open or close the water inlet 110, and then control the communication state between the water supply end and the steam generating chamber 410.

[0093] In this way, the paddle 523 extends the distance between the temperature switch 521 and the top rod 524, thereby extending the position of the heating plate 420 relative to the top rod 524 and the water inlet 110, expanding the position range of the water supply end, and facilitating the reasonable layout of the internal structure of the cooking device. In addition, the paddle 523 transmits the deformation of the temperature switch 521 to the top rod 524, reducing the size of the temperature switch 521 and reducing the production cost of the temperature switch 521.

[0094] Exemplarily, the temperature switch 521 can deform according to its own temperature change. Exemplarily, the material of the temperature switch 521 can be a temperature-sensitive material, such as a liquid crystal elastomer and a memory metal, or the temperature switch 521 uses a bimetallic material synthesized by pressing two metals with different thermal expansion and contraction coefficients.

[0095] In some embodiments, the temperature switch 521 is attached to the heating plate 420. Alternatively, the cooking device further includes a heat conducting member, and the heat of the heating plate 420 is transferred to the temperature switch 521 through the heat conducting member.

[0096] The temperature switch 521 fits the heating plate 420 , so that the temperature of the heating plate 420 is directly transferred to the temperature switch 521 , thereby improving the transfer efficiency and accuracy of the temperature of the heating plate 420 .

[0097] The cooking device also includes a heat conductor, through which the heat of the heating plate 420 is transferred to the temperature switch 521 , thereby extending the distance between the heating plate 420 and the temperature switch 521 , expanding the position range of the temperature switch 521 , and facilitating the reasonable layout of the position of the temperature switch 521 .

[0098] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the cooking device further includes: a water tank 900 , the water tank 900 is connected to the housing 100 , and the water supply pipeline 200 is connected to the water outlet of the water tank 900 .

[0099] The water tank 900 can contain water for delivery to the steam generating assembly 400, that is, the water tank 900 realizes the water storage function of the water supply end. The water tank 900 is connected to the housing 100, so that the housing 100 provides structural support for the water tank 900. Exemplarily, the water tank 900 is detachably connected to the housing 100, which facilitates the installation and replacement of the water tank 900, and the water storage operation after the water tank 900 is removed.

[0100] One end of the water supply pipe 200 is connected to the water tank 900, and the other two ends of the water supply pipe 200 are connected to the water inlet 110, so that the water tank 900 and the water inlet 110 are connected through the water supply pipe 200, which extends the distance between the water tank 900 and the water inlet 110, expands the position range of the water tank 900, and facilitates the reasonable layout of the water tank 900.

[0101] In some embodiments, optionally, with the bottom wall of the housing 100 as a reference plane, the water outlet of the water tank 900 is higher than the water inlet 110. The water outlet of the water tank 900 is higher than the water inlet 110, so that after the water in the water tank 900 flows out of the water tank 900, it can directly enter the water inlet 110 under the action of gravity, reducing auxiliary components such as water pumps, saving components required for water supply, and simplifying the structure of the water supply end.

[0102] In an embodiment of the utility model, the cooking device can be a steam stew pot, which is mainly composed of a water tank 900, a water control component 500, a steam generating component 400, and a cooking area. Its main features are: the water control component 500 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 storage structure due to temperature changes).

[0103] The steam generating assembly 400 may be Figure 1 As shown, the structure has a certain water storage function, and a heat source is provided at the bottom, which heats the liquid to generate steam during operation. The main function of the water tank 900 is to store water, and it needs to be placed at a higher position. The cooking area is located above the steam generating assembly 400, and steam enters the cooking area to cook food after being generated. The water tank 900, the water control assembly 500, and the steam generating assembly 400 are connected by pipelines.

[0104] The temperature switch 521 of the water control assembly 500 may be Figure 8 In the structure shown, when the temperature reaches a specific value, the deformation zone of the temperature switch 521 is deformed, the position of the paddle 523 changes to push the push rod 524, the push rod 524 pushes the valve assembly 510, the valve assembly 510 is deformed, the water-sealed opening is opened, and the water in the water tank 900 enters the steam generating assembly 400 (Note: the paddle 523 and the push rod 524 are not necessary structures, these structures are only the parts that transmit the deformation. In essence, the two deformation states or position states of the temperature switch 521 correspond to the two states of the water control assembly 500 of water intake and water non-intake. In theory, as long as the temperature response can be transmitted to the water control assembly 500, it will be fine).

[0105] After the work is completed, the water control component 500 is closed, and there may be residual water in the pipe between the water tank 900 and the water control component 500, which will affect the user's experience next time. To solve this problem, a branch pipe is set in the pipe between the water tank 900 and the water control component 500, namely the waste water pipe 600. The branch pipe is in a closed state in a normal state. The closing method is that the knob switch (valve body) protrudes to press the branch pipe. When the knob is rotated outward, the pressed branch pipe is loosened, and the residual water in the pipe flows into the waste water box 800 through the branch pipe. In addition, when the pipeline needs to be cleaned, the branch pipe can be loosened to open the passage to allow water to flow and complete the cleaning.

[0106] Working principle: When the cooking equipment is working, the steam generating component 400 is heated and the temperature is transmitted to the temperature switch 521. The temperature switch 521 is deformed to change the state of the water control component 500 from closed to open. Water flows through the pipeline to the water control component 500, and then flows to the steam generating component 400. At this time, the steam generating module is in a hot state. After the water enters, it is heated and evaporates rapidly to produce steam. At the same time, after the liquid water enters the steam generating module, the temperature of the hot plate will be reduced (heat exchange). After the temperature is reduced, the temperature switch 521 will be closed, and the water control component 500 will be further closed, ensuring that only a certain amount of water enters the steam generating component 400, thereby improving the steam generation efficiency.

[0107] The steam generating assembly 400 continues to heat, and after all the quantitative water is converted into steam, the heating plate 420 starts to heat up again, the temperature switch 521 is turned on, the water control assembly 500 is turned on, and water enters the steam generating assembly 400 again, and the above process is repeated, and cooking is finished.

[0108] Only heating an appropriate amount of water each time can quickly produce steam, and the water inlet is controlled by the temperature change of the heating plate 420, and the residual water in the pipeline can be discharged through the branch pipe.
