[0002] The steam cooker heats stew cup and food material in stew cup through water vapor, in order to guarantee the cooking speed, the temperature in the cooking cavity needs to be raised quickly and kept stable in the whole cooking process, that is, water needs to be stably supplied to the heating assembly and steam needs to be continuously generated.

[0003] In the cooking process, the user needs to manually control the water inlet and stop of the heating assembly, and the user needs to stay beside the steam cooker, thereby bringing inconvenience to the user's use of the steam cooker. UTILITY MODEL CONTENTS

[0004] The utility model aims at solving one of the technical problems existing in the prior art or related art.

[0005] Therefore, in a first aspect, the utility model provides a base assembly, which comprises: a base, a steam supply port being arranged on the base; a surrounding rib, which is arranged on the top of the base and is distributed along the circumference of the steam supply port, and a gap is arranged on the circumference of the surrounding rib, and a first part of the steam supply port is arranged opposite to the gap; a steam generating assembly, which is arranged in the base, and the steam generating assembly comprises a heating assembly and a steam generating piece, the heating assembly is used for heating water in the steam generating piece to generate steam, and the steam generating piece is in communication with the steam supply port; a water control assembly, which is arranged in the base, and the water control assembly comprises a temperature switch, the temperature of the temperature switch changes with the temperature change of the heating assembly, when the temperature of the temperature switch is greater than or equal to a first set temperature T1, the water control assembly is used for connecting a water supply end with the steam generating piece, 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 piece, T1 is greater than or equal to T2, and the first part and the temperature switch are distributed in a staggered manner in the height direction of the base based on the bottom surface of the base.

[0006] The steam generating assembly comprises the heating assembly and the steam generating piece, and the water of the water supply end can enter the steam generating piece through the pipeline. The heating assembly can make the water become steam by increasing the temperature. The base is provided with the steam supply port, the cooking equipment has a cooking cavity, and the steam in the steam generating piece can flow into the cooking cavity through the steam supply port, and the steam in the steam generating piece can heat the food material in the cooking cavity.

[0007] The water control assembly is arranged in the base. In the working state, the heating assembly is heated and warmed up, and the temperature of the temperature switch in the water control assembly changes with the heating assembly, that is, when the temperature of the heating assembly rises, the temperature of the temperature switch also rises. When the temperature of the temperature switch reaches the first set temperature, the passage between the water supply end and the steam generating element is opened, and the water in the water supply end can enter the steam generating element. In this case, the heating assembly is in a high-temperature state, and the water entering the steam generating element is rapidly evaporated to form steam. During the evaporation of the water in the steam generating element, the temperature of the heating assembly gradually decreases, and the temperature of the temperature switch also decreases. When the temperature of the temperature switch is less than the second set temperature, the water control assembly closes the passage between the water supply end and the steam generating element, and the water in the water supply end stops entering the steam generating element. In this case, the heating assembly can continue to warm up until the temperature of the temperature switch reaches the first set temperature again, the water control assembly opens the passage between the water supply end and the steam generating element again, and the above process is repeated.

[0008] In this way, the water control assembly can open or close the passage between the water supply end and the steam generating element according to the temperature of the temperature switch, thereby enabling the cooking device to control the water inlet state in the steam generating element through the temperature of the temperature switch. The cooking device realizes the automatic water inlet function, avoids the user manually opening or closing the water inlet, reduces the risk of long-time dry burning of the heating assembly, improves the water supply convenience and safety of the cooking device, and the user does not need to stay near the cooking device during cooking, which provides convenience for the user to use the cooking device. Moreover, the water control assembly ensures that a certain amount of water enters the steam generating element, the heating assembly heats the certain amount of water, improves the steam generation speed of the heating assembly, and is beneficial to shorten the cooking time.

[0009] In actual use conditions, the above-mentioned water inlet control scheme can be affected by various factors. During the working process, condensate water formed on the structure of the pot cover, the container and the like can flow back to the heating assembly through the steam supply port. Due to the structural limitation, the above-mentioned temperature switch is usually close to the edge of the heating disc, and the condensate water flowing back will first contact and evaporate the surface of the edge of the heating disc, thereby taking away a large amount of heat, so that the temperature of the temperature switch cannot normally reach the deformation temperature T1, and the water in the water supply end cannot normally enter the steam generating element. Only after the condensate water flowing back to the edge of the heating assembly is completely evaporated, the normal working can be restored. When the cooking device restores the normal working to generate steam, new condensate water is formed and flows back to the heating assembly, thereby causing the problem that the steam amount periodically decreases or is interrupted during the working process of the cooking device, and the temperature of the cooking cavity decreases, which greatly affects the product performance and the cooking effect of the food material.

[0010] To solve the above problems, the top of the base is provided with a drainage structure, that is, a surrounding rib is arranged on the top of the base, the surrounding rib is distributed along the circumference of the steam supply port, so that the surrounding rib can prevent the condensed water dripping on the top of the base from flowing to the steam supply port, a gap is arranged on the circumference of the surrounding rib, the gap is communicated with the steam supply port, that is, the condensed water on the top of the base can only flow to the steam supply port through the gap, the gap is arranged at a position corresponding to the first part in the steam supply port, and the condensed water on the top of the base drips into the steam generating element through the first part on the steam supply port.

[0011] The installation position of the temperature switch is distributed in a staggered manner with the first part, that is, the position where the condensed water drips on the heating assembly is distributed in a staggered manner with the temperature switch, so that the condensed water flows downward from a direction away from the installation position of the temperature switch, and when the condensed water flows back to the heating assembly, the condensed water does not immediately contact the installation position of the temperature switch, thereby reducing the adverse effect of the condensed water on the temperature switch and avoiding the influence of the heat absorption and evaporation of the condensed water on the temperature of the temperature switch.

[0012] In addition, the base assembly in the above technical solution provided by the utility model can also have the following additional technical features:

[0013] In some technical solutions, optionally, the second part in the steam supply port is arranged away from the gap, and the distance between the temperature switch and the first part is greater than the distance between the temperature switch and the second part.

[0014] The first part in the steam supply port corresponds to the position of the gap, and the second part in the steam supply port is arranged away from the gap, for example, the second part is arranged on the opposite side of the first part.

[0015] The distance between the temperature switch and the first part is relatively large, and the distance between the temperature switch and the second part is relatively small, so the temperature switch is closer to the second part, and the temperature switch is exemplarily arranged below the second part. In this way, the temperature switch is arranged away from the first part, so that the temperature switch is arranged away from the dripping position of the condensed water on the heating assembly, and the influence of the condensed water on the temperature of the temperature switch is further reduced.

[0016] In some technical solutions, optionally, the bottom of the base is a projection surface, the steam supply port and the temperature switch are projected on the projection surface, and the projection of the temperature switch is located outside the projection area of the steam supply port.

[0017] The bottom surface of the base is a projection surface, the steam supply port and the temperature switch are projected on the projection surface, and the projection of the temperature switch is distributed in a staggered manner with the projection of the steam supply port, that is, the projection of the temperature switch does not fall within the projection range of the steam supply port. The condensed water will fall on the heating assembly under the action of gravity, and when the relative positions of the temperature switch and the steam supply port satisfy the above conditions, it can be ensured that the condensed water will not drip on the installation position of the temperature switch, thereby avoiding the influence on the temperature of the temperature switch.

[0018] In some embodiments, the cross-sectional area of the steam generating element decreases from the bottom of the steam generating element to the top of the steam generating element.

[0019] The cross-sectional area of the bottom of the steam generating element is larger than the cross-sectional area of the top of the steam generating element, so that the steam generating element has a tapered structure. In the case where the heating assembly is arranged at the bottom of the steam generating element, the opening area of the steam supply port is smaller than the top area of the heating assembly, so that the gap on the side of the steam supply port and the temperature switch are misaligned.

[0020] In some embodiments, the rim is connected to the inner wall of the steam supply port.

[0021] In the present embodiment, the rim is arranged on the inner wall of the steam supply port, so that there is no gap between the rim and the inner wall of the steam supply port. The condensed water flowing through the rim directly flows into the steam supply port, without flowing between the rim and the steam supply port, so that the condensed water can pass through the steam supply port through the first part of the steam supply port, thereby ensuring that the dripping position of the condensed water on the heating assembly avoids the mounting position of the temperature switch.

[0022] In some embodiments, the inner wall of the steam supply port has a circumference L1, and the gap has a circumference L2. The circumference L1 is greater than or equal to 4 times the circumference L2.

[0023] The circumference L1 of the steam supply port and the circumference L2 of the gap satisfy L1≥4×L2, so that the circumference of the gap is not too large, thereby limiting the range of the condensed water flowing to the steam supply port, and ensuring that the dripping position of the condensed water on the heating assembly is away from the mounting position of the temperature switch.

[0024] In some embodiments, the height H of the rim satisfies H≥2mm.

[0025] The rim can block the condensed water on the top of the base. If the height of the rim is too low, the condensed water may flow over the rim when the condensed water accumulates on the top of the base, which causes the rim to fail to block the condensed water. In the present embodiment, the height of the rim is greater than or equal to 2mm, which ensures that the rim can stably block the condensed water on the top of the base.

[0026] In some embodiments, the top surface of the base is provided with the steam supply port, and the top surface is arranged to be inclined towards the steam supply port.

[0027] In the case where the top surface is arranged to be inclined towards the steam supply port, the steam supply port is arranged at a lower position, so that the condensed water can flow to the steam supply port and flow into the steam generating element.

[0028] In some embodiments, the notch is lower than the highest point on the top surface.

[0029] The notch is arranged at a lower position on the top surface, so that the condensed water can flow along the inclined surface to the notch, ensuring that the condensed water can flow to the steam generating element through the notch.

[0030] In some embodiments, the steam supply port is arranged at the lowest position on the top surface.

[0031] Since the steam supply port is arranged at the lowest position on the top surface, most of the condensed water on the top surface can flow to the steam supply port, avoiding excessive accumulation of condensed water on the top surface.

[0032] In some embodiments, the top of the heating assembly is arranged as a heating surface, and the height of at least a portion of the heating surface decreases from the edge of the heating surface to the middle of the heating surface, and the temperature switch is higher than the lowest point of the heating surface.

[0033] The top surface of the heating assembly is arranged in a form of high in the periphery and low in the middle, so that when the condensed water drops on the heating surface, the condensed water will flow to the low position along the heating surface, i.e., the condensed water will flow to the middle of the heating surface, the condensed water will be concentrated in the middle of the heating surface, and the condensed water will be evaporated and absorbed in the middle of the heating surface. The installation position of the temperature switch is higher than the lowest point of the heating surface, so that the condensed water is not easy to concentrate at the installation position of the temperature switch, thereby avoiding the influence of the condensed water on the temperature of the temperature switch.

[0034] In some embodiments, the water control assembly further comprises: a valve body shell connected to the heating assembly, the valve body shell being provided with a water inlet and a water inlet cavity, the water inlet being used for connecting the water supply end and the water inlet cavity, and the water inlet cavity being connected to the steam generating element; and an elastic sealing member located in the water inlet cavity; the temperature switch is used for driving the elastic sealing member to move, so that the elastic sealing member opens the water inlet, and the elastic sealing member closes the water inlet when the elastic sealing member is in an initial position.

[0035] The temperature switch can push the elastic sealing member, and the elastic sealing member opens the water inlet when the elastic sealing member is pushed, so that the water inlet pipeline connected to the water supply end is connected to the water inlet cavity, and the water of the water supply end flows into the steam generating element through the water inlet pipeline, the water inlet, and the water inlet cavity in sequence. When the temperature switch does not push the elastic sealing member, the elastic sealing member closes the water inlet, and the water of the water supply end cannot flow into the steam generating element.

[0036] The elastic sealing piece has stable high-elasticity effect, is easy to deform, and can be deformed by a small driving force, so that the triggering flexibility is improved, and the elastic sealing piece can be automatically reset under the elastic force when the temperature switch stops pushing the elastic sealing piece.

[0037] In some embodiments, the temperature switch comprises: a deformation portion connected to the heating assembly, the deformation portion deforms when the temperature of the deformation portion is greater than or equal to the first set temperature T1, and the deformation portion is in an original state when the temperature of the deformation portion is less than the second set temperature T2; and a pushing portion connected to the deformation portion, the pushing portion pushes the elastic sealing piece when the deformation portion deforms.

[0038] The pushing portion is in contact with the deformation portion, the pushing portion is overlapped on a position of the deformation portion where the deformation occurs, the deformation portion is used to push the pushing portion, and the pushing portion can move following the deformation of the deformation portion when the deformation portion deforms.

[0039] In this way, when the deformation portion and the elastic sealing piece are staggered, the linkage between the two can be realized by the pushing portion, so that the internal structure of the cooking device is arranged reasonably.

[0040] In a second aspect, the utility model provides a kind of cooking equipment, comprising: the base component in any of the above technical solutions.

[0041] The additional aspects and advantages of the utility model will become apparent from the following description, or be appreciated by practice of the utility model. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0053] In order to enable the above object, features and advantages of the utility model to be more clearly understood, the utility model will be further described below with reference to the drawings and specific embodiments. It should be explained that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0055] The following refers to Figures 1 to 8 The base assembly and the cooking equipment provided according to some embodiments of the utility model are described.

[0056] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of this utility model, a base assembly 100 is proposed, including: a base 110, a surrounding rib 140, a steam generating assembly 120, and a water control assembly 130. The base 110 is provided with a steam supply port 111, and the surrounding rib 140 is located at the top of the base 110, with the surrounding rib 140 extending circumferentially around the steam supply port 111. Figure 4 The arrow at point C points to the distribution, and the circumferential notch 141 is provided in the circumferential direction of the reinforcing bars 140. The first part 112 of the steam supply port 111 ( Figure 4 The area within the dashed box at reference number 112 represents the first part, and the size of the first part 112 is not limited to... Figure 4 The size shown in the dashed box is positioned opposite to the notch 141. A steam generating assembly 120 is located within the base 110. The steam generating assembly 120 includes a heating assembly 121 and a steam generator 122. The heating assembly 121 heats the water within the steam generator 122 to generate steam. The steam generator 122 is connected to the steam supply port 111. A water control assembly 130 is located within the base 110. The water control assembly 130 includes a temperature switch 131. The temperature of the temperature switch 131 changes with the temperature of the heating assembly 121. When the temperature of the temperature switch 131 is greater than or equal to the first set temperature T1, the water control assembly 130 connects the water supply end 200 to the steam generator 122. When the temperature of the temperature switch 131 is less than the second set temperature T2, the water control assembly 130 closes the passage between the water supply end 200 and the steam generator 122. T1 ≥ T2. With the bottom surface of the base 110 as a reference, in the height direction of the base 110 (… Figure 4 The arrow at h1 points upwards, and the first part 112 is misaligned with the temperature switch 131.

[0057] The steam generating assembly 120 includes a heating assembly 121 and a steam generator 122. Water from the water supply end 200 can enter the steam generator 122 through a pipe. The heating assembly 121 heats the water to produce steam. The base 110 is provided with a steam supply port 111. The cooking device has a cooking chamber 310. Steam from the steam generator 122 can flow into the cooking chamber 310 through the steam supply port 111, and the steam from the steam generator 122 can heat the food inside the cooking chamber.

[0058] The water control assembly 130 is arranged in the base 110. In the working state of the steam generating assembly 120, the heating assembly 121 is heated and warmed up, and the temperature of the temperature switch 131 in the water control assembly 130 changes with the heating assembly 121, that is, when the temperature of the heating assembly 121 rises, the temperature of the temperature switch 131 also rises. When the temperature of the temperature switch 131 reaches the first set temperature, the passage between the water supply end 200 and the steam generating element 122 is opened, and the water of the water supply end 200 can enter the steam generating element 122. In this case, the heating assembly 121 is in a high-temperature state, and the water entering the steam generating element 122 is rapidly evaporated to form steam. During the evaporation of the water in the steam generating element 122, the temperature of the heating assembly 121 gradually decreases, and the temperature of the temperature switch 131 also decreases. When the temperature of the temperature switch 131 is less than the second set temperature, the water control assembly 130 closes the passage between the water supply end 200 and the steam generating element 122, and the water of the water supply end 200 stops entering the steam generating element 122. In this case, the heating assembly 121 can continue to warm up until the temperature of the temperature switch 131 reaches the first set temperature again, the water control assembly 130 opens the passage between the water supply end 200 and the steam generating element 122 again, and the above process is repeated.

[0059] In this way, the water control assembly 130 can open or close the passage between the water supply end 200 and the steam generating element 122 according to the temperature of the temperature switch 131, so as to control the water inlet state in the steam generating element 122 through the temperature of the temperature switch 131. The cooking device realizes the automatic water inlet function, avoids the user manually opening or closing the water inlet port 136, reduces the risk of long-time dry burning of the heating assembly 121, improves the water supply convenience and safety of the cooking device, and the user does not need to stay near the cooking device during cooking, which provides convenience for the user to use the cooking device. Moreover, the water control assembly 130 ensures that a certain amount of water enters the steam generating element 122, and the heating assembly 121 heats the certain amount of water, which improves the steam generation speed of the heating assembly 121 and is beneficial to shorten the cooking time.

[0060] In actual use conditions, the above control water inlet scheme can be affected by various factors. Condensate formed on the structure of the pot cover, the container and the like during work can flow back to the heating assembly 121 along the steam supply port 111. Due to structural limitations, the temperature switch 131 is usually close to the edge of the heating disc, and the backflow condensate can first contact the surface of the edge of the heating disc and be heated and evaporated, thereby taking away a large amount of heat, causing the temperature of the temperature switch 131 to fail to normally reach the deformation temperature T1, and the water in the water supply end 200 failing to normally enter the steam generating piece 122, until the condensate backflowing to the edge of the heating assembly 121 is completely evaporated to restore normal work. When the cooking device resumes normal work to generate steam, newly formed condensate can flow back to the heating assembly 121, thereby causing the cooking device to periodically reduce or interrupt the amount of steam during work, and the temperature of the cooking cavity 310 to decrease, which greatly affects the product performance and the cooking effect of the food material.

[0061] To solve the above problem, the top of the base 110 is provided with a drainage structure, that is, a surrounding rib 140 is arranged on the top of the base 110, the surrounding rib 140 is distributed along the circumference of the steam supply port 111, so that the surrounding rib 140 can prevent the condensate dripping onto the top of the base 110 from flowing to the steam supply port 111. The surrounding rib 140 is provided with a gap 141 in the circumferential direction, the gap 141 is in communication with the steam supply port 111, that is, the condensate on the top of the base 110 can only flow to the steam supply port 111 through the gap 141, and the gap 141 is arranged at a position corresponding to the first part 112 in the steam supply port 111. The condensate on the top of the base 110 drips into the steam generating piece 122 through the first part 112 on the steam supply port 111.

[0062] The installation position of the temperature switch 131 is distributed in a staggered manner with the first part 112, that is, the position of the condensate dripping onto the heating assembly 121 is distributed in a staggered manner with the temperature switch 131, so that the condensate flows down from a direction away from the installation position of the temperature switch 131. In this way, when the condensate flows back to the heating assembly 121, it will not immediately contact the installation position of the temperature switch 131, thereby reducing the adverse effects of the condensate on the temperature switch 131, and avoiding the influence of the heat absorption and evaporation of the condensate on the temperature of the temperature switch 131.

[0063] The first set temperature T1 is greater than 100°C. For example, the first set temperature T1 is 110°C or 120°C.

[0064] Figure 4 In the above embodiment, the installation position of the temperature switch 131 corresponds to the dashed box at label a on the heating assembly 121.

[0065] In combination with Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, optionally, a second portion 113 of the steam supply port 111 is set Figure 4 The area in the dashed line box at reference numeral 113 is used to represent the second portion, and the size of the second portion 113 is not limited to Figure 4 The size and position shown in the dashed line box are such that the temperature switch 131 is farther away from the notch 141 than from the first portion 112.

[0066] The first portion 112 of the steam supply port 111 corresponds to the position of the notch 141, and the second portion 113 of the steam supply port 111 is away from the notch 141, for example, the second portion 113 is set on the opposite side of the first portion 112.

[0067] The temperature switch 131 is farther away from the first portion 112 than from the second portion 113, so the temperature switch 131 is closer to the second portion 113, and exemplarily, the temperature switch 131 is below the second portion 113. This arrangement can keep the temperature switch 131 away from the first portion 112, so that the temperature switch 131 is away from the position where the condensed water drops on the heating assembly 121, further reducing the temperature influence of the condensed water on the temperature switch 131.

[0068] In combination with Figure 2 and Figure 5 As shown, in some embodiments, optionally, the bottom of the base 110 is set as a projection surface, the steam supply port 111 and the temperature switch 131 are projected on the projection surface, and the projection of the temperature switch 131 is located outside the projection area of the steam supply port 111.

[0069] The bottom surface of the base 110 is set as a projection surface, the steam supply port 111 and the temperature switch 131 are projected on the projection surface, and the projection of the temperature switch 131 is distributed in a staggered manner with the projection of the steam supply port 111, that is, the projection of the temperature switch 131 does not fall within the projection range of the steam supply port 111. The condensed water will fall on the heating assembly 121 under the action of gravity, and in the case that the relative positions of the temperature switch 131 and the steam supply port 111 meet the above conditions, it can be ensured that the condensed water will not drop on the installation position of the temperature switch 131, thereby avoiding the temperature influence on the temperature switch 131.

[0070] In some embodiments, optionally, the cross-sectional area of the steam generation piece 122 decreases from the bottom of the steam generation piece 122 to the top of the steam generation piece 122.

[0071] The bottom cross-sectional area of ​​the steam generator 122 is larger, while the top cross-sectional area is smaller, resulting in a constricted structure. With the heating assembly 121 located at the bottom of the steam generator 122, the opening area of ​​the steam supply port 111 is smaller than the top area of ​​the heating assembly 121, which facilitates the staggered distribution of the notch 141 on the side of the steam supply port 111 and the temperature switch 131.

[0072] like Figure 4 As shown, in some embodiments, optionally, the reinforcing rib 140 is connected to the inner wall of the steam supply port 111.

[0073] In this design, the retaining rib 140 is installed on the inner wall of the steam supply port 111. Therefore, there is no gap between the retaining rib 140 and the inner wall of the steam supply port 111. The condensate flowing through the retaining rib 140 will flow directly into the steam supply port 111 and will not flow between the retaining rib 140 and the steam supply port 111. This ensures that the condensate can pass through the first part 112 in the steam supply port 111, thereby ensuring that the dripping position of the condensate on the heating component 121 avoids the installation position of the temperature switch 131.

[0074] like Figure 4 As shown, in some embodiments, optionally, the perimeter of the inner wall of the steam supply port 111 is L1, and the perimeter of the notch 141 along the circumference of the steam supply port 111 is L2, where L1≥4×L2.

[0075] The perimeter L1 of the steam supply port 111 and the perimeter L2 of the notch 141 satisfy L1≥4×L2, so that the opening perimeter of the notch 141 will not be too large, thereby limiting the range of condensate flowing to the steam supply port 111 and ensuring that the dripping position of condensate on the heating component 121 is far away from the installation position of the temperature switch 131.

[0076] In some embodiments, the height H of the reinforcing bar 140 may optionally satisfy H≥2mm.

[0077] The retaining rib 140 is designed to block condensation on the top of the base 110. If the height of the retaining rib 140 is too low, condensation may overflow the retaining rib 140 when it accumulates on the top of the base 110, causing the retaining rib 140 to fail to block condensation. In this design, the height of the retaining rib 140 is limited to 2mm or greater to ensure that the retaining rib 140 can stably block condensation on the top of the base 110.

[0078] In some technical solutions, optionally, a steam supply port 111 is provided on the top surface 114 of the base 110, and the top surface 114 is inclined toward the steam supply port 111.

[0079] In the case that the top surface 114 is inclined towards the steam supply port 111, the steam supply port 111 is arranged at a lower position, so that the condensed water can flow to the steam supply port 111 and then flow into the steam generating element 122.

[0080] In some embodiments, the notch 141 is arranged below the highest point on the top surface 114.

[0081] The notch 141 is arranged at a lower position on the top surface 114, so that the condensed water can flow along the inclined surface to the notch 141, and then flow into the steam generating element 122 through the notch 141.

[0082] In some embodiments, the steam supply port 111 is arranged at the lowest position on the top surface 114.

[0083] Since the steam supply port 111 is arranged at the lowest position on the top surface 114, most of the condensed water on the top surface 114 can flow to the steam supply port 111, so that the top surface 114 is not easily filled with too much condensed water.

[0084] In combination with Figure 2 and Figure 5 In some embodiments, the top of the heating assembly 121 is arranged as a heating surface 124, and the height of at least a portion of the heating surface 124 decreases from the edge of the heating surface 124 to the middle of the heating surface 124, and the temperature switch 131 is arranged higher than the lowest point of the heating surface 124.

[0085] The top surface of the heating assembly 121 is arranged as a periphery-high middle-low structure, so that when the condensed water drops on the heating surface 124, the condensed water can flow along the heating surface 124 to the low position, i.e., the condensed water can flow to the middle of the heating surface 124, and the condensed water can be concentrated in the middle of the heating surface 124 and then evaporated and absorbed. The installation position of the temperature switch 131 is arranged higher than the lowest point of the heating surface 124, so that the condensed water is not easily concentrated at the installation position of the temperature switch 131, thereby avoiding the condensed water affecting the temperature of the temperature switch 131.

[0086] In combination with Figure 2 and Figure 5 In some embodiments, the steam generating assembly 120 further includes the heating assembly 121, and the heating assembly 121 includes a heating disc 125 and a heating element 123, wherein the heating element 123 is connected to the heating disc 125 and is used to heat the heating disc 125, and the temperature switch 131 is arranged in contact with the heating disc 125 and is located at the side of the heating element 123.

[0087] During the operation of the steam generating assembly 120, the heating element 123 heats the heating disc 125, and the heating disc 125 can heat the water in the steam generating element 122. The temperature switch 131 is attached to the heating disc 125, so that the temperature of the temperature switch 131 is close to the temperature of the heating disc 125. In the present scheme, the temperature switch 131 is arranged near the heating element 123, so that the temperature of the heating element 123 can be quickly transmitted to the temperature switch 131 during the heating process, so that the temperature switch 131 can respond more quickly, and the temperature of the temperature switch 131 can more easily reach the first set temperature T1, so as to ensure that the steam generating element 122 can be watered in time.

[0088] As shown in Figure 5 , in some embodiments, the temperature switch 131 is arranged apart from the heating element 123.

[0089] The temperature switch 131 is attached to the heating disc 125, but the temperature switch 131 needs to be arranged apart from the heating element 123. The temperature change of the temperature switch 131 should be mainly affected by the temperature of the heating disc 125, and the temperature change of the heating disc 125 is used to reflect whether there is water in the steam generating element 122, so that the temperature switch 131 is arranged apart from the heating element 123, which can reduce the temperature influence of the heating element 123 on the temperature switch 131, and ensure that the temperature change of the temperature switch 131 can also accurately reflect whether there is water in the steam generating element 122, so as to ensure that the water control assembly 130 can accurately control the water filling time and the water stopping time.

[0090] As shown in Figure 2 , Figure 3 and Figure 5 , in some embodiments, the water control assembly 130 further comprises a valve body shell 132 and an elastic sealing element 138, the valve body shell 132 is connected with the heating assembly 121, the valve body shell 132 is provided with a water inlet 136 and a water inlet cavity 137, the water inlet 136 is used to communicate the water supply end 200 and the water inlet cavity 137, the water inlet cavity 137 is communicated with the steam generating element 122. The elastic sealing element 138 is located in the water inlet cavity 137, the temperature switch 131 is used to drive the elastic sealing element 138 to move, the elastic sealing element 138 is opened under the condition that the elastic sealing element 138 is pushed, the elastic sealing element 138 is closed under the condition that the elastic sealing element 138 is in the initial position.

[0091] The water supply end 200 and the water inlet 136 are connected by the water inlet pipe 135 in this embodiment. The temperature switch 131 can push the elastic sealing member 138. When the elastic sealing member 138 is pushed, the elastic sealing member opens the water inlet 136. At this time, the water inlet pipe 135 is connected with the water inlet cavity 137, and the water in the water supply end 200 flows into the steam generating member 122 through the water inlet pipe 135, the water inlet 136 and the water inlet cavity 137 in sequence. When the temperature switch 131 does not push the elastic sealing member 138, the elastic sealing member 138 closes the water inlet 136, and the water in the water supply end 200 cannot flow into the steam generating member 122.

[0092] The elastic sealing member 138 has a stable high-elasticity effect. The elastic sealing member 138 is easy to deform, and a small driving force can make the elastic sealing member 138 deform, thereby improving the triggering flexibility. When the temperature switch 131 stops pushing the elastic sealing member 138, the elastic sealing member 138 can automatically reset under the action of the elastic force. In addition, the elastic sealing member 138 is soft in texture, so the elastic sealing member 138 can be closely attached to the valve body shell 132, thereby effectively sealing the passage between the water supply end 200 and the steam generating member 122.

[0093] The valve body shell 132 includes a water valve upper cover 133 and a water valve lower cover 134. The elastic sealing member 138 is installed between the water valve upper cover 133 and the water valve lower cover 134. The water valve lower cover 134 is installed on the heating assembly 121. The elastic sealing member 138 is fixed on the water valve lower cover 134, and the water inlet hole is arranged on the water valve upper cover 133. When the temperature switch 131 pushes the elastic sealing member 138, part of the elastic sealing member 138 rises, thereby opening the water inlet 136.

[0094] Exemplarily, the elastic sealing member 138 is a rubber elastic member or a silica gel elastic member.

[0095] A communication pipe is arranged between the water inlet cavity 137 and the steam generating member 122. The water in the water inlet cavity 137 flows into the steam generating member 122 through the communication pipe.

[0096] In combination Figure 3 and Figure 5 As shown in FIG. 13, in a possible application, the water control assembly 130 further includes an elastic member 150. The elastic member 150 is sleeved on the elastic sealing member 138. When the elastic sealing member 138 is pushed, the elastic member 150 deforms. When the elastic sealing member 138 stops being pushed, the elastic member 150 assists the elastic sealing member 138 to reset by the elastic force.

[0097] As Figure 5As shown in some embodiments, the valve body shell 132 and the temperature switch 131 are connected to the heating assembly 121.

[0098] The various components in the water control assembly 130 are assembled on the same component, facilitating the control of assembly and dimensional error, avoiding the deviation in height after assembly when the components are assembled on different components, resulting in the deformation of the temperature switch 131 and the inability to push the elastic sealing element 138. In the present solution, the components are assembled on the heating assembly 121 of the steam generation assembly 120, ensuring the installation accuracy.

[0099] As shown in combination with Figure 3 , Figure 5 and Figure 6 , in some embodiments, the temperature switch 131 includes a deformation part 1311 and a pushing part 1312. The deformation part 1311 is connected to the heating assembly 121. When the temperature of the deformation part 1311 is greater than or equal to a first set temperature T1, the deformation part 1311 deforms. When the temperature of the deformation part 1311 is less than a second set temperature T2, the deformation part 1311 is in the original state. The pushing part 1312 is connected to the deformation part 1311. In the case that the deformation part 1311 deforms, the pushing part 1312 pushes the elastic sealing element 138.

[0100] The pushing part 1312 is in contact with the deformation part 1311. The pushing part 1312 is overlapped at the position where the deformation part 1311 can deform. The deformation part 1311 is used to push the pushing part 1312. In the case that the deformation part 1311 deforms, the pushing part 1312 can move following the deformation of the deformation part 1311.

[0101] In this way, in the case that the deformation part 1311 and the elastic sealing element 138 are distributed staggeredly, the linkage between the two can be realized through the pushing part 1312, facilitating the reasonable layout of the internal structure of the cooking equipment.

[0102] Figure 7 In the case of Figure 8 , the deformation part 1311 deforms and pushes the pushing part 1312, Figure 8 In the case of

[0103] The temperature switch 131 can deform according to the change of its own temperature. Exemplarily, the material of the temperature switch 131 can be a temperature-sensitive material, such as liquid crystal elastomer and memory metal, or the temperature switch 131 adopts a bimetallic material composed of two metals with different thermal expansion and cold contraction coefficients.

The cooking equipment further includes a cover 300, which is arranged on the base assembly 100, and a cooking cavity 310 is formed between the cover 300 and the base assembly 100.

[0107] The water tank is used for storing water, and is arranged at a higher position, and the steam generating assembly 120 is arranged at a lower position, so as to ensure that the water flows into the steam generating assembly 120 smoothly by gravity.

[0108] The water control assembly 130 cooperates with the water tank to supply water to the steam generating component 122, without the need to arrange a water pump to provide water power, so that the noise of the cooking equipment during operation can be reduced, and the user's comfort for using the cooking equipment can be improved.
