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, firstly, this utility model proposes a base assembly for a cooking device. The cooking device has a cooking cavity. The base assembly includes: a base with a steam supply port for communicating with the cooking cavity; a steam generating assembly disposed within the base, comprising a heating plate and a steam generating element, wherein the heating plate heats water within the steam generating element to generate steam, and the steam generating element is connected to the steam supply port; the heating plate includes a mounting portion; a shielding element disposed on the base or the steam generating element, the shielding element being located above the heating plate; and a water control assembly disposed within the base, comprising a temperature switch disposed on the mounting portion. The temperature of the temperature switch changes with the temperature of the heating plate. When the temperature of the temperature switch is greater than or equal to a first set temperature T1, the water control assembly connects the water supply end to the steam generating element. When the temperature of the temperature switch is less than a second set temperature T2, the water control assembly closes the passage between the water supply end and the steam generating element. When T1 ≥ T2, the shielding element projects onto the heating plate, and the mounting portion is located within the projection coverage area of ​​the shielding element.

[0006] After the water from the water supply end enters the steam generator, the heating plate raises the temperature and turns the water into steam. The steam in the steam generator can flow into the cooking cavity, thereby heating the food inside.

[0007] The water control component is located within the base. When the steam generator is operational, the heating plate heats up, and the temperature switch in the water control component adjusts accordingly; that is, as the heating plate temperature rises, the temperature switch temperature also rises. When the temperature switch reaches the first set temperature, 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 heating plate is at a high temperature, and the water entering the steam generator evaporates rapidly to form steam. During the evaporation process, the temperature of the heating plate gradually decreases, and the temperature switch temperature also decreases. When the temperature switch temperature falls below the second set temperature, the water control component closes the passage between the water supply and the steam generator, stopping water from entering the steam generator. In this state, the heating plate continues to heat up until the temperature switch temperature reaches the first set temperature again. Then, the water control component reopens the passage between the water supply and the steam generator, repeating the above 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 within 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 heating plate 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, and the heating plate heats this precise amount of water, increasing the speed at which the heating plate generates steam and helping to shorten cooking time.

[0009] Under actual usage conditions, the aforementioned water inlet control scheme is affected by various factors. During operation, condensation formed on the lid, container, and other structures flows back to the heating plate along the steam supply port. Due to structural limitations, the temperature switch is usually located near the edge of the heating plate. The returning condensation first contacts the surface of the heating plate edge and evaporates, carrying away a large amount of heat. This prevents the temperature switch from reaching its deformation temperature T1, and water from the water supply cannot properly enter the steam generator. Normal operation can only resume after all the condensation flowing back to the edge of the heating plate has evaporated. When the cooking equipment resumes normal operation and generates steam, newly formed condensation flows back to the heating plate, causing periodic reductions or interruptions in steam volume and a drop in cooking cavity temperature during operation. This significantly affects product performance and the cooking effect.

[0010] To address the aforementioned issues, a shielding element is installed on the base or steam generator. When the shielding element projects onto the heating plate, the mounting portion is located within the projection area of ​​the shielding element. As condensate drips downwards, the shielding element blocks the condensate, allowing it to drip from the unshielded area onto the heating plate. Condensate is less likely to drip from the projected area of ​​the shielding element on the heating plate, thus preventing it from contacting the mounting portion and affecting its temperature. With the temperature switch mounted on the mounting portion, its temperature is also less affected by the condensate, minimizing the adverse effects of condensate on the switch. In other words, it prevents the condensate's heat absorption and evaporation from affecting the switch's temperature. Under these conditions, the temperature switch can respond accurately and quickly, ensuring timely water intake for the steam generator. This reduces the likelihood of reduced or interrupted steam output during operation, improving the cooking results.

[0011] 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:

[0012] In some technical solutions, the shielding element can optionally be detachably connected to the base or the steam generator.

[0013] The shield is detachable, allowing users to remove it from the base or steam generator when not in use. Alternatively, the shield can be removed for separate cleaning, improving its ease of maintenance.

[0014] In some technical solutions, optionally, the base includes a top wall, a steam supply port is located on the top wall, a shield is located on the top wall, and a portion of the shield covers the steam supply port.

[0015] The steam generator is connected to the steam supply port, which is also connected to the cooking cavity. The steam generated inside the steam generator flows into the cooking cavity through the steam supply port.

[0016] In this design, the shielding component is installed on the top wall of the base. When the condensate drips directly onto the steam supply port, the shielding component covers part of the steam supply port, allowing the condensate to only drip through the area without a steam supply port, thus preventing the condensate from dripping onto the mounting area.

[0017] Similarly, when condensate drips onto the top wall, the condensate on the top wall will flow towards the steam supply port. If some of the condensate flows onto the shield, it will drip onto the heating plate after reaching the edge of the shield. The condensate will not drip within the projection range of the shield, thus preventing the condensate from affecting the temperature at the installation location.

[0018] The shielding component in this design can be removed from the top wall.

[0019] In some technical solutions, the shielding element can optionally be annular, and the shielding element is distributed circumferentially along the steam supply port.

[0020] In this design, the shielding component is a ring-shaped structure, distributed circumferentially around the steam supply port. Each ring-shaped shielding component has a through-hole at its center, connected to the steam supply port. The through-hole allows steam to pass through and condensate to drip onto the heating plate. By designing the shielding component as a ring, the condensate drips onto the heating plate closer to its center, thus keeping the dripping point away from the edge of the heating plate. This allows the mounting part to be conveniently placed at any position on the edge of the heating plate.

[0021] In some technical solutions, optionally, the shielding member is provided on the steam generator and the shielding member is located inside the steam generator.

[0022] In this design, the shield is installed inside the steam generator, and the shield is mounted on the inner wall of the steam generator. By embedding the shield inside the steam generator, the user is less likely to touch the shield when using the cooking appliance, thus preventing the shield from dislodging from its installation position.

[0023] The shielding component in this design can be detached from the steam generator.

[0024] In some technical solutions, optionally, a portion of the steam generator is provided with a shielding element along the circumference of the steam generator.

[0025] In the circumferential direction of the steam generator, only a portion of the steam generator is equipped with a shielding component. That is, the shielding component inside the steam generator is not a ring structure, which makes it easy to remove and insert the shielding component into the steam generator.

[0026] In some technical solutions, the shielding element may optionally be spaced apart from the top surface of the heating plate.

[0027] When the shielding component is installed inside the steam generator, it is spaced apart from the heating plate, meaning it is not in contact with the heating plate. During operation, the heating plate reaches a high temperature. Maintaining a gap between the shielding component and the heating plate prevents the shielding component from being affected by the high temperature of the heating plate, thereby reducing the damage rate of the shielding component.

[0028] In some technical solutions, the shielding element may optionally be set at an angle relative to the horizontal plane.

[0029] The shield is installed at an angle on the top wall or inside the shield generator. When condensate flows onto the shield, the condensate will flow along the shield and drip from the side of the shield that is lower onto the heating plate.

[0030] By setting the shield to be installed at an angle, condensate is less likely to flow along the bottom wall of the shield, thus preventing condensate from dripping into the projection area of ​​the shield.

[0031] In some technical solutions, optionally, the first side of the heating plate faces the steam generator, and with the horizontal plane as a reference, a part of the mounting part is higher than the lowest point on the first side of the heating plate.

[0032] The first side of the heating plate faces the steam generator, and this first side is the top surface of the heating plate. A portion of the mounting part is higher than the lowest point of the top of the heating plate. Therefore, when condensate drips onto the heating plate, the condensate will flow to a lower position and will not accumulate at the mounting part, thus preventing continuous evaporation and heat dissipation of the condensate at the mounting part and avoiding affecting the temperature of the temperature switch.

[0033] In some technical solutions, optionally, a steam supply port is provided on the top wall of the base, and the top wall is inclined toward the steam supply port.

[0034] In some technical solutions, the base assembly may optionally include a perimeter, which is disposed on the top wall and distributed circumferentially along the steam supply port. The perimeter has a notch in the circumferential direction, through which condensate on the top wall flows into the steam generator.

[0035] In some technical solutions, optionally, the mounting part and the notch are misaligned in a direction perpendicular to the horizontal plane.

[0036] In some technical solutions, the shielding element and the notch are optionally separated.

[0037] Secondly, this utility model proposes a cooking device, including a base assembly as described in the first aspect.

[0038] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

Detailed Implementation

[0050] 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.

[0051] 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.

[0052] The following reference Figures 1 to 8 This invention describes a base assembly and cooking device provided according to some embodiments of the present invention.

[0053] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments of this utility model, a base assembly 100 is provided. The base assembly 100 is used for a cooking device 200, which has a cooking cavity 210. The base assembly 100 includes: a base 110, a steam generating assembly 120, a shielding member 140, and a water control assembly 130. A steam supply port 112 is provided on the base 110, which communicates with the cooking cavity 210. The steam generating assembly 120 is disposed within the base 110 and includes a heating plate 121 and a steam generator 122. The heating plate 121 heats the water in the steam generator 122 to generate steam. The steam generator 122 communicates with the steam supply port 112, and the heating plate 121 includes a mounting portion 127. The shielding member 140 is disposed on the base 110 or the steam generator 122, and is located above the heating plate 121. The water control component 130 is located inside the base 110. The water control component 130 includes a temperature switch 131, which is mounted on the mounting part 127. 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 the first set temperature T1, the water control component 130 connects the water supply end 300 to the steam generator 122. When the temperature of the temperature switch 131 is less than the second set temperature T2, the water control component 130 closes the passage between the water supply end 300 and the steam generator 122. When T1≥T2, the shielding member 140 projects onto the heating plate 121, and the mounting part 127 is located within the projection coverage area of ​​the shielding member 140.

[0054] After the water from the water supply end 300 enters the steam generator 122, the heating plate 121 can heat the water and turn it into steam by raising the temperature. The steam in the steam generator 122 can flow into the cooking chamber 210, thereby heating the food inside.

[0055] The water control component 130 is housed within the base 110. When the steam generating component 120 is operational, the heating plate 121 heats up. The temperature of the temperature switch 131 within the water control component 130 changes with the temperature of the heating plate 121; that is, as the temperature of the heating plate 121 increases, the temperature of the temperature switch 131 also increases. When the temperature of the temperature switch 131 reaches a first set temperature, the passage between the water supply end 300 and the steam generating component 122 is opened, allowing water from the water supply end 300 to enter the steam generating component 122. In this state, the heating plate 121 is at a high temperature, and the water entering the steam generating component 122 is rapidly heated and evaporates to form steam. During the evaporation process, the temperature of the heating plate 121 gradually decreases, and the temperature of the temperature switch 131 also decreases. When the temperature of the temperature switch 131 is lower than the second set temperature, the water control component 130 closes the passage between the water supply end 300 and the steam generator 122, and the water from the water supply end 300 stops entering the steam generator 122. Under these circumstances, the heating plate 121 can continue to heat up until the temperature of the temperature switch 131 reaches the first set temperature again. Then, the water control component 130 reopens the passage between the water supply end 300 and the steam generator 122, and repeats the above process.

[0056] Thus, the water control component 130 can open or close the passage between the water supply terminal 300 and the steam generator 122 according to the temperature of the temperature switch 131, thereby enabling the cooking equipment 200 to control the water intake state in the steam generator 122 through the temperature of the temperature switch 131. This allows the cooking equipment 200 to achieve automatic water intake, avoiding the need for the user to manually open or close the water inlet, reducing the risk of prolonged dry burning of the heating plate 121, and improving the convenience and safety of water supply to the cooking equipment 200. During the cooking process, the user does not need to be present next to the cooking equipment 200, providing convenience for the user's use of the cooking equipment 200. Furthermore, the water control component 130 ensures that a fixed amount of water enters the steam generator 122, and the heating plate 121 heats the fixed amount of water, increasing the speed at which the heating plate 121 generates steam, which helps to shorten the cooking time.

[0057] Under actual usage conditions, the aforementioned water inlet control scheme is affected by various factors. During operation, condensate formed on the lid, container, and other structures flows back to the heating plate 121 via the steam supply port 112. Due to structural limitations, the temperature switch 131 is usually located near the edge of the heating plate. The flowing condensate first contacts the surface of the heating plate's edge and evaporates, carrying away a large amount of heat. This prevents the temperature switch 131 from reaching its deformation temperature T1, and water in the water supply end 300 cannot properly enter the steam generator 122 until all the condensate flowing back to the edge of the heating plate 121 has evaporated, at which point normal operation can resume. When the cooking device 200 resumes normal operation and generates steam, newly formed condensate flows back to the heating plate 121, causing the cooking device 200 to periodically experience a reduction or interruption in steam volume and a decrease in the temperature of the cooking chamber 210 during operation. This significantly affects product performance and the cooking effect of the food.

[0058] To solve the above problems, a shielding member 140 is provided on the base 110 or the steam generator 122. When the shielding member 140 is projected onto the heating plate 121, the mounting part 127 is located within the projection coverage area of ​​the shielding member 140. Figure 6 In the diagram, the dashed line at point A indicates the position of the mounting part 127 on the top surface of the heating plate 121, with the mounting part 127 positioned below the dashed line. When condensate drips downwards, the shielding member 140 can block the condensate, allowing it to drip onto the heating plate 121 from the area where the shielding member 140 is not present. Condensate is less likely to drip from the projection of the shielding member 140 onto the heating plate 121, thus preventing the condensate from contacting the mounting part 127 and minimizing its impact on the temperature of the mounting part 127. Since the temperature of the mounting part 127 is not affected by the condensate, the temperature of the temperature switch 131 is also less likely to be affected, reducing the adverse effects of condensate on the temperature switch 131. In other words, it prevents the condensate from absorbing heat and evaporating, thus avoiding any impact on the temperature of the temperature switch 131. In this situation, the temperature switch 131 can respond accurately and quickly, ensuring that the steam generator 122 receives water in time. This prevents the cooking equipment 200 from experiencing a reduction or interruption in steam volume during operation, which is beneficial for improving the cooking effect on the ingredients.

[0059] In one possible application, the steam generating assembly 120 further includes a heating element 124 connected to the heating plate 121 for heating the heating plate 121. Exemplarily, the heating element 124 may be a heating tube or a heating wire.

[0060] In one possible application, the first set temperature is greater than 100°C; for example, the first set temperature is 110°C or 120°C.

[0061] In some embodiments, the shield 140 may optionally be detachably connected to the base 110 or the steam generator 122.

[0062] The shield 140 is detachable, allowing the user to remove it from the base 110 or the steam generator 122 when it is not in use. Alternatively, the shield 140 can be removed and cleaned separately, improving the ease of cleaning.

[0063] For example, the shield 140 is locked to the base 110 or the steam generator 122 by screws or clips.

[0064] Combination Figure 6 and Figure 7 As shown, in some embodiments, optionally, the base 110 includes a top wall 113, a steam supply port 112 is disposed on the top wall 113, a shield 140 is disposed on the top wall 113, and a portion of the shield 140 covers the steam supply port 112.

[0065] The interior of the steam generator 122 is connected to the steam supply port 112, which is also connected to the cooking chamber 210. The steam generated in the steam generator 122 flows into the cooking chamber 210 through the steam supply port 112.

[0066] In this design, the shielding member 140 is installed on the top wall 113 of the base 110. When the condensate drips directly onto the steam supply port 112, the shielding member 140 covers part of the steam supply port 112, so that the condensate can only pass through the position where the steam supply port 112 is not provided, thereby preventing the condensate from dripping onto the arrangement position of the mounting part 127.

[0067] Similarly, when condensate drips onto the top wall 113, the condensate on the top wall 113 will flow towards the steam supply port 112. When some of the condensate flows onto the shield 140, the condensate will drip onto the heating plate 121 after flowing to the edge of the shield 140. The condensate will not drip into the projection range of the shield 140, thereby preventing the condensate from affecting the temperature at the installation position of the mounting part 127.

[0068] The shielding component 140 in this design can be detached from the top wall 113.

[0069] Combination Figure 6 and Figure 7 As shown, in some embodiments, optionally, the shield 140 is annular, and the shield 140 is circumferential along the steam supply port 112. Figure 7 The arrow at point C points to the distribution.

[0070] In this design, the shielding member 140 is an annular structure, distributed circumferentially around the steam supply port 112. The annular shielding member 140 has a through hole at its center, which connects to the steam supply port 112. The through hole allows steam to pass through and allows condensate to drip onto the heating plate 121. By configuring the shielding member 140 as an annular structure, the dripping position of condensate on the heating plate 121 is close to the center of the heating plate 121, thus keeping the dripping position away from the edge of the heating plate 121. This allows the mounting part 127 to be conveniently positioned at any location on the edge of the heating plate 121.

[0071] Combination Figure 6 and Figure 8 As shown, in some embodiments, optionally, the shielding member 140 is disposed on the steam generator 122, and the shielding member 140 is located inside the steam generator 122.

[0072] In this design, the shield 140 is installed inside the steam generator 122, and the shield 140 is installed on the inner wall of the steam generator 122. By embedding the shield 140 inside the steam generator 122, the user is less likely to touch the shield 140 when using the cooking device 200, thus preventing the shield 140 from falling out of its installation position.

[0073] The shielding component 140 in this design can be detached from the steam generator 122.

[0074] Combination Figure 6 and Figure 8 As shown, in some embodiments, optionally, along the circumferential direction of the steam generator 122 ( Figure 7 (The arrow at point C points to) A portion of the steam generator 122 is equipped with a shielding element 140.

[0075] In the circumferential direction of the steam generator 122, only a portion of the steam generator 122 is provided with a shielding member 140. That is, the shielding member 140 provided in the steam generator 122 is not a ring structure, which makes it easy to remove and put the shielding member 140 into the steam generator 122.

[0076] In some embodiments, the shield 140 is optionally spaced apart from the top surface of the heating plate 121.

[0077] When the shielding member 140 is installed inside the steam generator 122, the shielding member 140 is spaced apart from the heating plate 121, that is, the shielding member 140 is not in contact with the heating plate 121. When the steam generator 120 is running, the heating plate 121 has a high temperature. Leaving a gap between the shielding member 140 and the heating plate 121 can prevent the shielding member 140 from being affected by the high temperature of the heating plate 121, thereby reducing the damage rate of the shielding member 140.

[0078] In some embodiments, the shielding member 140 is optionally inclined relative to the horizontal plane 111.

[0079] The shield 140 is installed at an angle in the top wall 113 or inside the shield 140 generator. When condensate flows onto the shield 140, the condensate will flow along the shield 140 and drip from the side of the shield 140 with a lower height onto the heating plate 121.

[0080] By setting the shield 140 to be installed at an angle, condensate is less likely to flow along the bottom wall of the shield 140, thereby preventing condensate from dripping onto the projection area of ​​the shield 140.

[0081] Combination Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, optionally, the first side of the heating plate 121 faces the steam generator 122, and with the horizontal plane 111 as a reference, a portion of the mounting portion 127 is higher than the lowest point on the first side of the heating plate 121.

[0082] The first side of the heating plate 121 faces the steam generator 122, and the first side of the heating plate 121 is the top surface of the heating plate 121. A portion of the mounting portion 127 is higher than the lowest point of the top of the heating plate 121. Therefore, when condensate drips onto the heating plate 121, the condensate will flow to a lower position and will not accumulate at the mounting portion 127, thus preventing the condensate from continuously evaporating and dissipating heat at the mounting portion 127 and thus avoiding affecting the temperature of the temperature switch 131.

[0083] During operation, it is necessary to prevent condensate from flowing directly to the mounting position of temperature switch 131. Instead, the condensate should first come into contact with other areas of heating plate 121. Therefore, a shield can be installed within the projection area of ​​the mounting position of temperature switch 131. The method of shielding is not limited. For example, a separate removable baffle 140 can be installed on the top wall 113 of base 110 as a shielding component. It is installed on the top wall 113 during use and can be removed for cleaning after use, preventing condensate from flowing directly to the fixed position of temperature switch 131 during operation. Alternatively, a partial shielding structure can be designed directly on the top wall 113. Whether the shielding feature is fixed or removable, its projected area must at least cover the projection of the mounting part 127 and be higher than the heating plate 121.

[0084] like Figure 6 As shown, in some embodiments, optionally, a steam supply port 112 is provided on the top wall 113 of the base 110, and the top wall 113 is inclined toward the steam supply port 112.

[0085] Since the top wall 113 is inclined toward the steam supply port 112, when there is condensate on the top wall 113, the condensate can flow along the top wall 113 to the steam supply port 112, avoiding the accumulation of condensate on the top wall 113 and reducing the amount of cleaning work for the user.

[0086] like Figure 6 As shown, in some embodiments, optionally, the base 110 assembly includes a perimeter 150, which is disposed on the top wall 113. The perimeter 150 is distributed circumferentially along the steam supply port 112, and a notch 151 is provided circumferentially on the perimeter 150. Condensate on the top wall 113 flows into the steam generator 122 through the notch 151.

[0087] The steam supply port 112 has a circumferential rim 150 with a notch 151. The rim 150 blocks condensate from the top wall 113, allowing condensate to flow into the steam generator 122 only through the notch 151. By providing the notch 151 on the circumferential rim 150, condensate flows into the steam generator 122 at a specific point. Adjusting the position where condensate flows into the steam generator 122 can improve the effect of condensate on the temperature switch 131.

[0088] like Figure 6 As shown, in some embodiments, optionally, the mounting portion 127 and the notch 151 are misaligned in the direction perpendicular to the horizontal plane 111.

[0089] When the mounting part 127 and the notch 151 are misaligned, and condensate flows into the steam generator 122 through the notch 151, the dripping position of the condensate on the heating plate 121 avoids the mounting position of the mounting part 127. This makes it difficult for the condensate to come into contact with the position on the heating plate 121 corresponding to the mounting part 127, and avoids the condensate from evaporating and affecting the temperature of the mounting part 127. This ensures that the temperature switch 131 can respond stably according to the temperature of the mounting part 127.

[0090] like Figure 6 As shown, in some embodiments, the shield 140 is optionally separated from the notch 151.

[0091] The shield 140 is used to shield the condensate dripping directly from the top of the cooking cavity, and the notch 151 is used to prevent the condensate on the top wall 113 from being positioned above the mounting part 127 on the heating plate 121. Therefore, the shield 140 needs to be positioned above the mounting part 127, and the notch 151 needs to be positioned above the mounting part 127. Separating the shield 140 and the notch 151 helps to improve the rationality of their arrangement and reduces the impact of condensate on the temperature of the mounting part 127.

[0092] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the water control assembly 130 further includes: a valve body housing 133 and an elastic seal 135. The valve body housing 133 is connected to the heating plate 121, and the valve body housing 133 is provided with a water inlet 134, which is connected to the steam generator 122. The elastic seal 135 is disposed on the valve body housing 133. The temperature switch 131 is used to drive the elastic seal 135 to move relative to the valve body housing 133. When the elastic seal 135 is pushed by the temperature switch 131, the elastic seal 135 opens the water inlet 134 so that the water inlet 134 is connected to the water supply end 300. When the elastic seal 135 is in the initial position, the elastic seal 135 closes the water inlet 134.

[0093] Temperature switch 131 can push elastic seal 135. When elastic seal 135 is pushed, it opens water inlet 134, connecting water supply end 300 to connecting pipe, allowing water from water supply end 300 to flow into steam generator 122 through connecting pipe. When temperature switch 131 does not push elastic seal 135, it closes water inlet 134, preventing water from water supply end 300 from flowing into steam generator 122.

[0094] When the temperature switch 131 stops pushing the elastic seal 135, the elastic seal 135 can automatically reset under the action of elastic force, realizing the function of automatically opening and closing the water inlet 134. In addition, the elastic seal 135 is relatively soft, so the elastic seal 135 can fit tightly with the valve body shell 133, which helps to improve the sealing effect of the water inlet 134.

[0095] The temperature switch 131 directly actuates the elastic seal 135, eliminating the need for any intermediate components between them. This avoids issues caused by installation errors between the intermediate components and the valve body housing 133, preventing the intermediate components from failing to lift the elastic seal 135 or the elastic seal 135 from failing to close the inlet 134 under the action of the intermediate components after the temperature switch 131 returns to its original position. By eliminating intermediate components, the stability of the fit between the temperature switch 131 and the elastic seal 135 is ensured, as well as the ability of the elastic seal 135 to reliably open and close the inlet 134.

[0096] The valve body housing 133 is mounted on the heating plate 121, which facilitates the control of assembly and dimensional errors and avoids deviations in height after assembly when each component is assembled on different components. This prevents the temperature switch 131 from deforming and failing to push the elastic seal 135, thus ensuring installation accuracy.

[0097] For example, the resilient seal 135 is a rubber resilient or a silicone resilient.

[0098] Combination Figure 4 and Figure 5 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 mounting portion 127. 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 elastic seal 135.

[0099] 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.

[0100] Thus, with the deformable part 1311 and the elastic seal 135 staggered, the linkage between the two can be achieved by the pushing part 1312, which facilitates the rational layout of the internal structure of the cooking equipment 200.

[0101] 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.

[0102] The water control assembly 130 also includes a connecting pipe 132, which is an integral structure with the elastic seal 135. The water inlet 134 is connected to the steam generator 122 through the connecting pipe 132.

[0103] The connecting pipe 132 is connected to the elastic seal 135, and the connecting pipe 132 is integrally formed into the elastic seal 135. Therefore, it is not necessary to process the connecting pipe 132 and the elastic seal 135 separately, which reduces the processing difficulty of the water control component 130 and can also improve the installation accuracy of the connecting pipe 132 and the elastic seal 135.

[0104] like Figure 4As shown, in some embodiments, optionally, the resilient seal 135 includes: a movable part 136 and an elastic part 137, the temperature switch 131 is used to push the movable part 136, the end of the movable part 136 is used to open or close the water inlet 134, the elastic part 137 is connected to the movable part 136 and the valve body housing 133, and the elastic part 137 deforms when the movable part 136 is pushed.

[0105] Temperature switch 131 can push movable part 136, which moves relative to valve body housing 133 and opens water inlet 134. An elastic part 137 is provided between movable part 136 and valve body housing 133. During the movement of movable part 136, the elastic part deforms, accumulating elastic potential energy. When temperature switch 131 stops pushing movable part 136, the elastic part, through its elastic force, drives movable part 136 to move back to its original position, thereby closing water inlet 134.

[0106] A portion of the elastic seal 135 is configured to fit the inlet 134, thereby tightly closing the inlet 134. Another portion of the elastic seal 135 is configured to be deformable, thereby stably driving the movable part 136 to reset.

[0107] Combination Figure 4 and Figure 5 As shown, in some embodiments, the resilient seal 135 may optionally include a spring 138, which is sleeved on the movable part 136 and located between the movable part 136 and the valve body housing 133. When the movable part 136 is pushed, the spring 138 deforms.

[0108] A spring 138 is fitted onto the movable part 136, with one end of the spring 138 abutting against the movable part 136 and the other end abutting against the valve body housing 133. When the movable part 136 is pushed, the spring 138 is compressed; when the movable part 136 stops being pushed, the spring 138, together with the elastic part 137, drives the movable part 136 to reset. By adding the spring 138 as the component driving the movable part 136 to reset, the reset stability of the movable part 136 can be improved, ensuring that the movable part 136 can stably close the water inlet 134 and preventing water overflow caused by continuous water entering the steam generator 122.

[0109] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, at least a portion of the elastic seal 135 is located inside the valve body housing 133, the valve body housing 133 is provided with an installation port 139, one end of the elastic seal 135 extends out of the installation port 139, the temperature switch 131 is used to push one end of the movable part 136, and the other end of the elastic seal 135 is used to open or close the water inlet 134.

[0110] The valve body housing 133 is provided with a mounting port 139 for the elastic seal 135 to extend out. The temperature switch 131 can push a portion of the elastic seal 135 extending out of the mounting port 139. A portion of the elastic seal 135 is installed inside the valve body housing 133, and the valve body housing 133 limits the elastic seal 135 to prevent it from dislodging from its mounting position.

[0111] The valve body housing 133 includes an upper valve body cover 1331 and a lower valve body cover 1332. A portion of the resilient seal 135 is installed between the upper valve body cover 1331 and the lower valve body cover 1332. The lower valve body cover 1332 is mounted on the heating plate 121. A water inlet 134 is located on the upper valve body cover 1331, and a mounting port 139 is located on the upper valve body cover 1331. When the temperature switch 131 pushes the resilient seal 135, a portion of the resilient seal 135 descends, thereby opening the water inlet 134.

[0113] For example, the cooking appliance 200 can be a steam stew pot, a steam cooking machine, etc.

[0114] Combination Figure 1 and Figure 2 As shown, the water supply end 300 includes a water tank for storing water, 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. When the water supply end 300 and the connecting pipe 132 are connected, the water tank and the steam generator 122 are connected by a communicating vessel principle to allow water to enter the steam generator 122. The cooking device 200 also includes a cover 400, which is mounted on the base assembly 100, forming a cooking cavity 210 between the cover 400 and the base assembly 100.
