Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking equipment technology, and more specifically, to a base assembly and a cooking device. Background Technology
[0002] Steam cookers heat the stew pot and the food inside using steam. To ensure cooking speed, the temperature inside the cooking chamber needs to rise rapidly and remain stable throughout the cooking process, which requires a stable supply of water to the heating element and continuous steam generation.
[0003] During the cooking process, users need to manually control the water supply to and from the heating element, requiring them to stay by the steam cooker, which is inconvenient for users. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] In view of this, in a first aspect, the present invention proposes a base assembly for a cooking device, the cooking device having a cooking cavity, the base assembly comprising: a base; a steam generating assembly disposed within the base, the steam generating assembly comprising a heating element and a steam generating element, the heating element being used to heat the steam generating element, the steam generating element having a groove, with the bottom surface of the base as a reference, at least a portion of the heating element being higher than the bottom wall of the groove; and a water control assembly disposed within the base, the water control assembly comprising a temperature switch, the temperature of the temperature switch changing with the temperature of the heating plate, the water control assembly being used to connect the water supply end to the steam generating element when the temperature of the temperature switch is greater than or equal to a first set temperature T1, and at least a portion of the temperature switch being offset from the groove in a direction perpendicular to the bottom surface.
[0006] Water from the water supply end can enter the steam generator through pipes. The steam generator heats up, causing the water to turn into steam. The cooking equipment has a cooking chamber, and the steam in the steam generator heats the food inside.
[0007] The water control component is located inside the base. When the steam generator is in operation, the steam generator heats up, and the temperature switch in the water control component changes accordingly; that is, as the temperature of the steam generator rises, the temperature switch also rises. When the temperature switch reaches the first set temperature T1, the passage between the water supply and the steam generator is opened, allowing water from the supply end to enter the steam generator. In this state, the steam generator is at a high temperature, and the water entering the generator evaporates rapidly to form steam. During the evaporation process, the temperature of the steam generator gradually decreases, and the temperature switch also decreases. When the temperature switch temperature falls below the second set temperature T2, the water control component closes the passage between the water supply and the steam generator, stopping water from entering. The steam generator continues to heat up until the temperature switch temperature reaches the first set temperature T1 again. Then, the water control component reopens the passage between the water supply and the steam generator, repeating the process.
[0008] In this way, the water control component can open or close the passage between the water supply and the steam generator based on the temperature of the temperature switch, thereby allowing the cooking equipment to control the water intake status of the steam generator through the temperature switch. This enables the cooking equipment to automatically fill with water, eliminating the need for users to manually open or close the water inlet, reducing the risk of the steam generator burning dry for extended periods, and improving the convenience and safety of water supply. Users do not need to be present during cooking, providing greater convenience. Furthermore, the water control component ensures a precise amount of water enters the steam generator, which heats this precise amount of water, increasing the rate at which steam is generated and helping to shorten cooking time.
[0009] In order to ensure that the water intake-boiling-re-water intake process can proceed smoothly, the temperature switch usually only rises to the first set temperature after the water in the steam generator has boiled dry. This is because the actual temperature of the temperature switch during the boiling stage must be lower than the first set temperature to avoid the water in the steam generator overflowing due to water not being boiled dry in the previous operation. For this reason, there is a certain amount of time between the water boiling dry and the temperature switch reaching the first set temperature, and the water supply end introducing water into the steam generator. This will cause several problems: (1) No steam is generated during this time, that is, the steam is discontinuous, which will affect the food. (1) The cooking effect of the ingredients; (2) The steam generator is also in a dry-burning state during this period, and the overall temperature is high, which affects the service life. If a coating is used, it will affect the reliability of the coating; (3) During this period, the steam generator will rise to a high temperature. In the early stage of water intake, obvious modal boiling will occur. The heat transfer between the steam generator and water is slow. On the one hand, the violent boiling of water at this time will generate noise, and hot water may splash out and injure people. On the other hand, since the temperature of the steam generator cannot be reduced quickly, the heating element cannot be restored to work quickly due to the influence of thermistors or temperature controllers and other protective devices, which further prolongs the steam interruption time.
[0010] Because the groove can store a certain amount of water, as the water in the steam generator gradually evaporates, the temperature of the part of the steam generator not covered by water will rise. However, the temperature at the bottom of the groove will not rise excessively if the water in the groove is not completely boiled away. Since at least a part of the temperature switch is misaligned with the groove, the temperature of the temperature switch is not significantly affected by the temperature at the bottom of the groove. When the part of the steam generator that has boiled away begins to heat up, it will cause the temperature switch to heat up as well. During the temperature switch's heating process, steam is still generated inside the steam generator because the water in the groove has not been completely boiled away. This solution, by heating the water inside the groove and generating steam when water begins to enter the steam generator, helps to achieve uninterrupted steam supply throughout the entire operation, greatly shortening the dry-burning time of the entire steam generator assembly, avoiding or reducing steam interval problems, and lowering the maximum temperature reached and the area affected by dry burning during the dry-burning stage of the steam generator, thus improving the reliability of the steam generator assembly.
[0011] The heating element is used to heat the steam generator, and at least a portion of the heating element is higher than the bottom wall of the groove. This allows the heating element to be moved away from the bottom of the steam generator, which can increase the speed at which the heating element heats the water and thus improve the steam generation rate.
[0012] In addition, the base assembly according to the above-described technical solution provided by this utility model may also have the following additional technical features:
[0013] In some technical solutions, optionally, the heating element is staggered with the bottom wall of the groove in a direction perpendicular to the bottom surface.
[0014] The heating element is offset from the bottom wall of the groove, meaning that the heating element is not located at the bottom of the groove, thus enabling the heating element to quickly heat the water above the bottom of the groove.
[0015] In some technical solutions, the heating element may optionally be annular, with at least a portion of the groove located within the annular region of the heating element.
[0016] In this design, the heating element is defined as an annular shape, and the annular heating element is distributed along the circumference of the groove, forming a shape in which the groove extends into the annular structure of the heating element. This arrangement is beneficial to improving the heating efficiency of the water in the groove and increasing the steam generation rate.
[0017] In some technical solutions, optionally, the distance between the bottom of the steam generator and the heating element is L1, and the distance between the heating element and the groove is L2, where L1 < L2.
[0018] The heating elements are distributed circumferentially along the groove, and the distance between the bottom of the steam generator and the heating elements is small, while the distance between the side of the groove and the heating elements is large. This brings the heating elements close to the bottom of the steam generator, preventing overheating and damage in areas with little water when there is little water in the steam generator (especially in the groove). Furthermore, the heating elements are closer to the edge of the steam generator, making it easier for dry burning to occur near the water control component, which is beneficial to the operation of the water control component.
[0019] In some technical solutions, optionally, a first direction is set parallel to the bottom surface, and in the first direction, at least a portion of the temperature switch overlaps with the heating element.
[0020] In this design, the temperature switch is positioned near the heating element. This allows the temperature of the heating element to be transferred to the temperature switch more quickly during the heating process, enabling the temperature switch to respond faster and reach the first set temperature T1 more easily, thus ensuring that the steam generator can be fed with water in a timely manner.
[0021] In some technical solutions, optionally, in a direction perpendicular to the bottom surface, the top of the temperature switch is flush with the top of the heating element, or at least a portion of the temperature switch is higher than the heating element.
[0022] When the temperature switch is flush with the heating element, the distances from the temperature switch and the heating element to the bottom of the heating plate are equal. When the temperature switch is higher than the heating element, the distance between the temperature switch and the bottom of the heating plate is smaller than the distance between the heating element and the bottom of the heating plate. By limiting the distance between the temperature switch and the heating plate, the temperature of the temperature switch is more sensitive to the influence of the heating plate.
[0023] In some technical solutions, the temperature switch and the heating element are optionally staggered in the direction perpendicular to the bottom surface.
[0024] The temperature change of the temperature switch should be mainly affected by the temperature of the steam generator. The temperature change of the steam generator is used to detect whether there is water inside the steam generator. Therefore, setting the temperature switch and the heating element separately can reduce the temperature influence of the heating element on the temperature switch, and ensure that the temperature change of the temperature switch can also accurately detect whether there is water inside the steam generator. This ensures that the water control component can accurately control the timing of water intake and the timing of stopping water intake.
[0025] In some technical solutions, the steam generator may optionally include a heating plate and a shroud, with the heating plate located at the bottom of the shroud, a groove provided on the heating plate, and the top surface of the heating plate used to heat the water inside the shroud to generate steam.
[0026] The bottom of the heating plate is sealed, forming a cavity between the heating plate and the cover. The heating element heats the heating plate, causing its temperature to rise. The top surface of the heating plate heats the water, generating steam. Both the grooved and non-grooved areas on the heating plate can heat water and generate steam. As the water evaporates, the water in the non-grooved areas of the heating plate boils dry first. Because the temperature switch is staggered with the grooves, it is directly opposite the non-grooved area. When the non-grooved area begins to heat up, the temperature switch also heats up, allowing the water in the grooves to continue heating and generating steam, thus minimizing steam interruption.
[0027] In some technical solutions, optionally, the distance between the edge of the top surface of the heating plate and the heating element is greater than the distance between the edge of the top surface of the heating plate and the temperature switch.
[0028] The distance between the top edge of the heating plate and the heating element is relatively large, while the distance between the top edge of the heating plate and the temperature switch is relatively small. Therefore, the temperature switch is located outside the heating element, that is, the temperature switch is not set in the area enclosed by the heating element. This can reduce the temperature influence of the heating element on the temperature switch, thereby ensuring that the water control component accurately controls the timing of water inlet and water stoppage.
[0029] In some technical solutions, optionally, a steam generator is used to heat the water in the groove to generate steam, which flows from the opening of the groove into the cooking cavity.
[0030] The grooves in the steam generator are used to store water. Areas on the steam generator without grooves will not be covered by water. When water enters the steam generator, it only enters the grooves. When the water in the grooves is heated, steam is discharged from the openings of the grooves.
[0031] In some technical solutions, the opening area of the groove may optionally be larger than the area of the portion of the top surface of the steam generator that is not provided with a groove.
[0032] Since the area on the steam generator without a groove will not be covered by water, in order to increase the water storage capacity of the groove and improve its volume, this solution limits the opening area of the groove to be larger than the area of the part on the top surface of the steam generator without a groove, thereby increasing the opening area of the groove and enabling it to store a larger amount of water.
[0033] In some technical solutions, optionally, the water control assembly further includes: a valve body shell connected to a steam generator, the valve body shell having an inlet pipe, an inlet port, and an inlet cavity, the inlet pipe and the inlet cavity being connected through the inlet port, and the inlet cavity being connected to the steam generator; an elastic seal located in the inlet cavity; and a push rod slidably connected to the valve body shell, one end of the push rod contacting the elastic seal, and the other end of the push rod contacting a temperature switch, the temperature switch being used to drive the push rod to move relative to the valve body shell, the elastic seal opening the inlet port when pushed by the push rod, and closing the inlet port when the elastic seal is in its initial position.
[0034] The temperature switch actuates the push rod, which in turn pushes the elastic seal. When the elastic seal is pushed, it opens the water inlet, connecting the water inlet pipe to the water inlet cavity. Water from the supply end flows sequentially through the water inlet pipe, the water inlet, and the water inlet cavity into the steam generator. When the temperature switch does not push the push rod, the push rod does not push the elastic seal, and the elastic seal closes the water inlet, preventing water from flowing into the steam generator.
[0035] The elastic seal possesses stable and highly elastic properties. It is easily deformable, requiring only a small driving force to induce deformation, thus improving triggering flexibility. When the push rod stops pushing the elastic seal, it automatically resets under the action of its elastic force. Furthermore, the elastic seal is relatively soft, allowing it to fit tightly against the valve body shell, effectively sealing the passage between the water supply and steam generator.
[0036] Secondly, this utility model proposes a cooking device, including: the cooking device as described in any of the above technical solutions.

Detailed Implementation
[0054] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0055] Many specific details are set forth in the following description in order to provide 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 scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0056] The following reference Figures 1 to 13 This invention describes a base assembly and cooking device provided according to some embodiments of the present invention.
[0057] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of this utility model, a base assembly 100 is proposed. The base assembly 100 is used for a cooking device, which has a cooking cavity 310. The base assembly 100 includes: a base 110, a steam generating assembly 120, and a water control assembly 130. The steam generating assembly 120 and the water control assembly 130 are both disposed within the base 110. The steam generating assembly 120 includes a heating element 123 and a steam generating element 122. The heating element 123 is used to heat the steam generating element 122. A groove 127 is provided on the steam generating element 122. With the bottom surface 111 of the base 110 as a reference, at least a portion of the heating element 123 is higher than the bottom wall of the groove 127. The water control assembly 130 includes a temperature switch 131. The temperature of the temperature switch 131 changes with the temperature of the heating plate 121. When the temperature of the temperature switch 131 is greater than or equal to a first set temperature T1, the water control assembly 130 is used to connect the water supply end 200 with the steam generating element 122 in a direction perpendicular to the bottom surface 111. Figure 3 (As indicated by the arrow at point H), at least a portion of the temperature switch 131 is misaligned with the groove 127.
[0058] Water from the water supply end 200 can enter the steam generator 122 through a pipe. The temperature of the steam generator 122 rises, causing the water to heat up and turn into steam. The cooking equipment has a cooking chamber 310, and the steam in the steam generator 122 can heat the food inside the cooking chamber.
[0059] The water control component 130 is housed within the base 110. When the steam generating component 120 is operational, the steam generator 122 heats up. The temperature of the temperature switch 131 within the water control component 130 changes with the temperature of the steam generator 122; that is, as the temperature of the steam generator 122 increases, the temperature of the temperature switch 131 also increases. When the temperature of the temperature switch 131 reaches the first set temperature T1, the passage between the water supply end 200 and the steam generator 122 is opened, allowing water from the water supply end 200 to enter the steam generator 122. In this state, the steam generator 122 is at a high temperature, and the water entering the steam generator 122 is rapidly heated and evaporates to form steam. During the evaporation process, the temperature of the steam generator 122 gradually decreases, and the temperature of the temperature switch 131 also decreases. When the temperature of temperature switch 131 is lower than the second set temperature T2, water control component 130 closes the passage between water supply end 200 and steam generator 122, and water from water supply end 200 stops entering steam generator 122. Under these circumstances, steam generator 122 can continue to heat up until the temperature of temperature switch 131 reaches the first set temperature T1 again. Then, water control component 130 reopens the passage between water supply end 200 and steam generator 122, and repeats the above process.
[0060] Thus, the water control component 130 can open or close the passage between the water supply end 200 and the steam generator 122 according to the temperature of the temperature switch 131, thereby enabling the cooking equipment to control the water intake state in the steam generator 122 through the temperature of the temperature switch 131. This enables the cooking equipment to achieve automatic water intake, avoiding the need for the user to manually open or close the water inlet 136, reducing the risk of prolonged dry burning of the steam generator 122, and improving the convenience and safety of water supply to the cooking equipment. During the cooking process, the user does not need to be by the cooking equipment, providing convenience for the user's use of the cooking equipment. Furthermore, the water control component 130 ensures that a fixed amount of water enters the steam generator 122, and the steam generator 122 heats the fixed amount of water, increasing the speed at which the steam generator 122 generates steam, which helps to shorten the cooking time.
[0061] To ensure the smooth operation of the water intake-boiling-re-water intake process, the temperature switch 131 usually only reaches the first set temperature after the water in the steam generator 122 has boiled dry. This is because the actual temperature of the temperature switch 131 during the boiling stage must be lower than the first set temperature to avoid the previous water not being boiled dry before water is added, which would cause the water in the steam generator 122 to overflow. For this reason, there is a certain amount of time between the water boiling dry and the temperature switch 131 reaching the first set temperature, and the water supply end 200 adding water to the steam generator 122. This will lead to several problems: (1) No steam is generated during this time, that is, the steam is discontinuous, which will affect the operation of the steam generator 122. (1) The cooking effect of the ingredients is affected; (2) The steam generator 122 is also in a dry burning state during this period, and the overall temperature is high, which affects the service life. If a coating is used, it will affect the reliability of the coating; (3) During this period, the steam generator 122 will rise to a high temperature. In the early stage of water intake, obvious modal boiling will occur. The heat transfer between the steam generator 122 and water is slow. On the one hand, the violent boiling of water at this time will generate noise, and hot water may splash out and injure people. On the other hand, since the temperature of the steam generator 122 cannot be reduced quickly, the steam generator 122 cannot be restored to work quickly due to the influence of thermistors or temperature controllers and other protective devices, which further prolongs the steam interruption time.
[0062] Because the groove 127 can store a certain amount of water, as the water in the steam generator 122 gradually evaporates, the temperature of the part of the steam generator 122 not covered by water will rise. However, the temperature at the bottom of the groove 127 will not rise excessively if the water in the groove 127 is not completely evaporated. Since at least a portion of the temperature switch 131 is misaligned with the groove 127, the temperature of the temperature switch 131 is not significantly affected by the temperature at the bottom of the groove 127. When the part of the steam generator 122 where the water has evaporated begins to heat up, it will cause the temperature switch 131 to heat up as well. During the heating process of the temperature switch 131, steam is still generated in the steam generator 122 because the water in the groove 127 has not been completely evaporated. With this solution, when water begins to enter the steam generator 122, the water inside the groove 127 is heated and steam is generated, which helps to achieve the purpose of uninterrupted steam throughout the working process, greatly shortens the dry burning time of the entire steam generator assembly 120, avoids the problem of steam interval or shortens the steam interval time, and reduces the maximum temperature reached by the steam generator 122 during the dry burning stage and the area where dry burning occurs, thereby improving the reliability of the steam generator 122.
[0063] The heating element 123 is used to heat the steam generator 122, and at least a portion of the heating element 123 is higher than the bottom wall of the groove 127. This allows the heating element 123 to be moved away from the bottom of the steam generator 122, thereby increasing the speed at which the heating element 123 heats the water and improving the steam generation speed.
[0064] In one possible application, the first set temperature T1 is greater than 100°C. For example, the first set temperature T1 is 110°C or 120°C.
[0065] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, the heating element 123 and the bottom wall of the groove 127 are misaligned in a direction perpendicular to the bottom surface 111.
[0066] The heating element 123 is misaligned with the bottom wall of the groove 127, that is, the heating element 123 is not located at the bottom of the groove 127, so that the heating element 123 can heat the water above the bottom of the groove 127.
[0067] Combination Figure 4 and Figure 5 As shown, in some embodiments, the heating element 123 is optionally annular, and at least a portion of the groove 127 is located within the annular region of the heating element 123.
[0068] In this design, the heating element 123 is defined as an annular shape, and the annular heating element 123 is distributed along the circumference of the groove 127, forming a shape in which the groove 127 extends into the annular structure of the heating element 123. This arrangement is beneficial to improving the heating efficiency of the water in the groove 127 and increasing the steam generation rate.
[0069] In some embodiments, the distance between the bottom of the steam generator 122 and the heating element 123 is L1, and the distance between the heating element 123 and the groove 127 is L2, where L1 < L2.
[0070] The heating element 123 is distributed circumferentially along the groove 127, and the distance between the bottom of the steam generator 122 and the heating element 123 is small, while the distance between the side of the groove 127 and the heating element 123 is large. This makes the heating element 123 close to the bottom of the steam generator 122, so that when the amount of water in the steam generator 122 is small, the problem of overheating and damage to the part without water is avoided.
[0071] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, a first direction is set ( Figure 3 The arrow at point D points parallel to the bottom surface 111. In the first direction, at least a portion of the temperature switch 131 overlaps with the heating element 123.
[0072] In this design, the temperature switch 131 is positioned near the heating element 123. This allows the temperature of the heating element 123 to be transferred to the temperature switch 131 more quickly during the heating process, enabling the temperature switch 131 to respond more quickly and reach the first set temperature T1 more easily, thus ensuring that the steam generator 122 can be filled with water in a timely manner.
[0073] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, in a direction perpendicular to the bottom surface 111, the top of the temperature switch 131 is flush with the top of the heating element 123, or at least a portion of the temperature switch 131 is higher than the heating element 123.
[0074] When the temperature switch 131 is flush with the heating element 123, the distances from the temperature switch 131 and the heating element 123 to the bottom of the heating plate 121 are equal. When the temperature switch 131 is higher than the heating element 123, the distance between the temperature switch 131 and the bottom of the heating plate 121 is smaller than the distance between the heating element 123 and the bottom of the heating plate 121. By limiting the distance between the temperature switch 131 and the heating plate 121, the temperature of the temperature switch 131 is more sensitively affected by the heating plate 121.
[0075] Combination Figure 4 and Figure 5 As shown, in some embodiments, the temperature switch 131 and the heating element 123 are optionally staggered in the direction perpendicular to the bottom surface 111.
[0076] The temperature change of temperature switch 131 should be mainly affected by the temperature of steam generator 122. The temperature change of steam generator 122 is used to detect whether there is water in steam generator 122. Therefore, by setting temperature switch 131 and heating element 123 separately, the temperature influence of heating element 123 on temperature switch 131 can be reduced, ensuring that the temperature change of temperature switch 131 can also accurately detect whether there is water in steam generator 122, thereby ensuring that water control component 130 accurately controls the timing of water intake and water intake stoppage.
[0077] Combination Figure 3 and Figure 12 As shown, in some embodiments, optionally, the steam generator 122 includes a heating plate 121 and a cover 128. The heating plate 121 is located at the bottom of the cover 128, and a groove 127 is provided on the heating plate 121. The top surface of the heating plate 121 is used to heat the water in the cover 128 to generate steam.
[0078] The bottom of the heating plate 121 is sealed by the cover 128, forming a cavity between the heating plate 121 and the cover 128. The heating element 123 heats the heating plate 121, causing its temperature to rise. The top surface of the heating plate 121 heats water to generate steam. Both the location with the groove 127 and the location without the groove 127 on the heating plate 121 can heat water to generate steam. As the water evaporates, the water in the location without the groove 127 on the heating plate 121 dries up first. Because the temperature switch 131 is misaligned with the groove 127, the temperature switch 131 is directly opposite the location without the groove 127 in the heating plate 121. When the location without the groove 127 starts to heat up, the temperature switch 131 heats up as well. At this time, the water in the groove 127 continues to be heated to generate steam, making it less likely for the steam to be interrupted.
[0079] like Figure 5 As shown, in some embodiments, optionally, the distance between the edge of the top surface of the heating plate 121 and the heating element 123 is greater than the distance between the edge of the top surface of the heating plate 121 and the temperature switch 131.
[0080] The distance between the edge of the top surface of the heating plate 121 and the heating element 123 is relatively large, while the distance between the edge of the top surface of the heating plate 121 and the temperature switch 131 is relatively small. Therefore, the temperature switch 131 is located outside the heating element 123, that is, the temperature switch 131 is not set in the area enclosed by the heating element 123. This can reduce the temperature influence of the heating element 123 on the temperature switch 131, thereby ensuring that the water control assembly 130 accurately controls the timing of water inlet and water stoppage.
[0081] like Figure 13 As shown, in some embodiments, optionally, the steam generator 122 is used to heat the water in the groove 127 to generate steam, which flows from the opening of the groove 127 to the cooking chamber 310.
[0082] The groove 127 of the steam generator 122 is used to store water. The areas of the steam generator 122 without the groove 127 will not be covered by water. When water enters the steam generator 122, the water will only enter the groove 127. When the water in the groove 127 is heated, steam will be discharged from the opening of the groove 127.
[0083] like Figure 13 As shown, in some embodiments, optionally, the opening area of the groove 127 is larger than the area of the portion of the top surface of the steam generator 122 where the groove 127 is not provided.
[0084] Since the area on the steam generator 122 without the groove 127 will not be covered by water, in order to increase the water storage capacity of the groove 127, the opening area of the groove 127 is limited to be larger than the area of the part on the top surface of the steam generator 122 without the groove 127, so that the opening area of the groove 127 is larger and the groove 127 can have a larger water storage capacity.
[0085] Combination Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the water control assembly 130 further includes: a valve body housing 132, an elastic seal 138, and a push rod 139. The valve body housing 132 is connected to the steam generator 122. The valve body housing 132 is provided with a water inlet pipe 135, a water inlet 136, and a water inlet cavity 137. The water inlet pipe 135 and the water inlet cavity 137 are connected through the water inlet 136, and the water inlet cavity 137 is connected to the steam generator 122. The elastic seal 138 is located in the water inlet cavity 137. The push rod 139 is slidably connected to the valve body shell 132. One end of the push rod 139 is in contact with the elastic seal 138, and the other end of the push rod 139 is in contact with the temperature switch 131. The temperature switch 131 is used to drive the push rod 139 to move relative to the valve body shell 132. When the elastic seal 138 is pushed by the push rod 139, the elastic seal 138 opens the water inlet 136. When the elastic seal 138 is in the initial position, the elastic seal 138 closes the water inlet 136.
[0086] Temperature switch 131 can push push rod 139, which in turn pushes elastic seal 138. When elastic seal 138 is pushed, it opens water inlet 136, connecting water inlet pipe 135 to water inlet cavity 137. Water from supply end 200 flows sequentially into steam generator 122 through water inlet pipe 135, water inlet 136, and water inlet cavity 137. When temperature switch 131 does not push push rod 139, push rod 139 does not push elastic seal 138, and elastic seal 138 closes water inlet 136, preventing water from supplying end 200 from flowing into steam generator 122.
[0087] The elastic seal 138 has a stable and highly elastic effect. It is easily deformable, requiring only a small driving force to deform, thus improving triggering flexibility. When the push rod 139 stops pushing the elastic seal 138, it automatically resets under the action of elastic force. Furthermore, the elastic seal 138 is relatively soft, allowing it to fit tightly against the valve body housing 132, effectively sealing the passage between the water supply end 200 and the steam generator 122.
[0088] The valve body housing 132 includes a water valve upper cover 133 and a water valve lower cover 134, with an elastic seal 138 installed between the water valve upper cover 133 and the water valve lower cover 134. The water valve lower cover 134 is mounted on the heating plate 121. The elastic seal 138 is fixed to the water valve lower cover 134, and the water inlet is located on the water valve upper cover 133. When the push rod 139 pushes the elastic seal 138, a portion of the elastic seal 138 rises, thereby opening the water inlet 136.
[0089] For example, the resilient seal 138 is a rubber resilient or a silicone resilient.
[0090] In some embodiments, the valve body housing 132 and the temperature switch 131 are both connected to the heating plate 121.
[0091] All components in the water control assembly 130 are assembled on the same component, which facilitates the control of assembly and dimensional errors and avoids the deviation in height after assembly when each component is assembled on different components, which would cause the temperature switch 131 to deform and fail to push the push rod 139. In this solution, all components are assembled on the heating plate 121 of the steam generating assembly 120 to ensure installation accuracy.
[0092] Combination Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, optionally, the temperature switch 131 includes a deformable portion 1311 and a pushing portion 1312. The deformable portion 1311 is connected to the heating plate 121. When the temperature of the deformable portion 1311 is greater than or equal to a first set temperature T1, the deformable portion 1311 deforms. When the temperature of the deformable portion 1311 is less than a second set temperature T2, the deformable portion 1311 remains in its original state. The pushing portion 1312 is connected to the deformable portion 1311. When the deformable portion 1311 deforms, the pushing portion 1312 pushes the push rod 139.
[0093] The pushing part 1312 contacts the deformable part 1311. The pushing part 1312 overlaps the deformable part 1311 at a position where deformation can occur. The deformable part 1311 is used to push the pushing part 1312. When the deformable part 1311 deforms, the pushing part 1312 can move in accordance with the deformation of the deformable part 1311.
[0094] One end of the push rod 139 contacts the push part 1312, and the other end of the push rod 139 contacts the elastic seal 138. Exemplarily, the push part 1312 can be a strip plate, with both ends connected to the deformable part 1311 and the push rod 139, respectively. This allows the push part 1312 to push the push rod 139 as it moves following the deformable part 1311, thereby enabling the push rod 139 to push the elastic seal 138 to open or close the passage between the water supply end 200 and the steam generator 122.
[0095] Thus, with the deformation section 1311 and the push rod 139 staggered, the linkage between the two can be achieved through the push section 1312, which facilitates the rational layout of the internal structure of the cooking equipment.
[0096] Figure 10 In the middle, the deformable part 1311 did not deform and did not push the pushing part 1312. Figure 11 In the middle, the deformable part 1311 deforms and pushes the pushing part 1312. Figure 11 The left side of the central propulsion unit 1312 curves upward.
[0097] Temperature switch 131 can deform according to its own temperature change. For example, the material of temperature switch 131 can be a temperature-sensitive material, such as liquid crystal elastomer and memory metal, or temperature switch 131 can be a bimetallic material made of two metals with different coefficients of thermal expansion and contraction.
[0098] Combination Figure 6 and Figure 7 As shown, in some embodiments, optionally, the water inlet pipe 135 includes a pipe bottom wall 1351, a recess 1352 is provided on the pipe bottom wall 1351, and the water inlet 136 is provided on the recess 1352.
[0099] The bottom wall of the water inlet pipe 135 is designated as the pipe bottom wall 1351. A recessed portion 1352 is located on the pipe bottom wall 1351, lower than other positions within the pipe bottom wall 1351. The water inlet 136 is located on the inner wall of the recessed portion 1352. Because the recessed portion 1352 has a recessed structure, it is positioned at a lower level within the pipe bottom wall 1351, allowing water in the water inlet pipe 135 to easily flow towards the recessed portion 1352, ensuring smooth water intake.
[0100] like Figure 7As shown, in some embodiments, optionally, the first end of the water inlet pipe 135 is connected to the water inlet 136, and the water inlet pipe 135 is inclined toward the water inlet 136 from the second end of the water inlet pipe 135 to the first end of the water inlet pipe 135.
[0101] Incline the water inlet pipe 135 toward the water inlet hole so that the water inside the water inlet pipe 135 can gather toward the water inlet 136, thereby improving the smoothness of water intake.

[0103] For example, the cooking equipment can be a steam stew pot, a steam cooking machine, etc.
[0104] The water supply end 200 includes a water tank, which is mounted on the base assembly 100. The water control assembly 130 is used to open or close the passage between the water tank and the steam generator 122. The cooking device also includes a cover 300, which covers the base assembly 100, forming a cooking cavity 310 between the cover 300 and the base assembly 100.
[0105] The water tank is used to store water and is located at a higher position, while the steam generating assembly 120 is located at a lower position, ensuring that the water flows smoothly into the steam generating assembly 120 by gravity.
[0106] Water is supplied to the steam generator 122 by the water control component 130 in conjunction with the water tank. There is no need to set up a water pump to provide water inlet power, so the noise of the cooking equipment during operation can be reduced and the user's comfort in using the cooking equipment can be improved.
