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 having a cooking cavity, the base assembly comprising: a base; a steam generating assembly disposed within the base, the steam generating assembly including a heating plate and a steam generating element, the heating plate being used to heat water within the steam generating element to provide steam to the cooking cavity; a temperature detection element connected to the steam generating assembly, the temperature detection element being used to detect the temperature of the heating plate, controlling the heating plate to stop heating when the temperature of the heating plate is greater than or equal to a first set temperature T1, and controlling the heating plate to start heating when the temperature of the heating plate is less than the first set temperature T1; and a water control assembly disposed within the base, the water control assembly including a temperature switch, the temperature of the temperature switch changing with the temperature of the heating plate, the temperature switch being disposed adjacent to the temperature detection element, 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 second set temperature T2, and the water control assembly being used to close the passage between the water supply end and the steam generating element when the temperature of the temperature switch is less than a third set temperature T3, where T2>T1, T2≥T3.

[0006] The steam generating assembly includes a heating plate and a steam generator. Water from the water supply end can enter the steam generator through pipes. The heating plate heats the water, turning it into steam. The cooking equipment has a cooking chamber, where the steam from the steam generator heats the food being cooked.

[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 second set temperature T2, 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 third set temperature T3, the water control component closes the passage between the water supply and the steam generator, stopping water from entering the steam generator. Under these conditions, the heating plate continues to heat up until the temperature switch temperature reaches the second set temperature T2 again. The water control component then 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 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] During the heating process of the heating plate, if there is water in the steam generator, the temperature of the heating plate will rise to a certain value and then remain basically stable. If the heating plate continues to rise from a stable temperature, it indicates that the water in the steam generator has boiled away. When the temperature of the heating plate reaches the first set temperature T1, the heating plate is controlled to stop heating; that is, the first set temperature T1 is the jump-off temperature of the heating plate. By controlling the heating plate to stop heating, prolonged dry burning of the heating plate can be avoided, preventing damage to the heating plate and related circuits due to high temperatures. After water enters the steam generator, the temperature inside the heating plate decreases. When the temperature of the heating plate decreases, the heating plate is controlled to resume heating.

[0010] In this design, the temperature switch and temperature sensor are placed adjacent to each other, meaning no other components are placed between them. This shortens the installation distance between the temperature switch and the temperature sensor. Placing the temperature sensor near the temperature switch allows for better control of the temperature switch based on the sensor's temperature. Since both the temperature sensor and the temperature switch are affected by the heating element's temperature, their close proximity minimizes the difference in their measured temperature values, thus avoiding errors in the control process. Changes in the size or power of the steam generating components will not affect the normal operation of the system.

[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 steam generating assembly may optionally include: a heating element connected to a heating plate, the heating element being used to heat the heating plate, and a temperature switch and a temperature sensing element located on the same side of the heating element.

[0013] The heating element heats the heating plate, and once the temperature of the heating plate rises, it can heat the water in the steam generator. The heat from the heating element affects the temperature switch and the temperature sensor. By placing the temperature switch and the temperature sensor on the same side of the heating element, the effects of the heating element on the temperature switch and the temperature sensor are essentially the same, thereby improving the synchronization of the temperature response of the temperature switch and the temperature sensor.

[0014] In some technical solutions, the heating element may optionally include: a heating part; a wiring part connected to the heating part, wherein the minimum distance between the heating part and the temperature detection element is less than the minimum distance between the wiring part and the temperature detection element.

[0015] The wiring section is used to connect to external wiring, and the heating section is used to generate heat. Therefore, in the heating element, the heating section is the main heat source. In this design, the distance between the temperature detection element and the heating section is limited to a small area, that is, the temperature detection element is close to the personnel area of ​​the heating element, so that the temperature detection element can detect temperature changes more quickly and thus respond rapidly.

[0016] In some technical solutions, optionally, the distance between the temperature sensing element and the temperature switch is L, where L satisfies 0mm≤L≤1cm.

[0017] In this design, the distance between the temperature sensor and the temperature switch is limited to less than or equal to 1 cm. Therefore, the temperature sensor and the temperature switch are placed close to each other. This allows for better control of the temperature switch based on the temperature of the temperature sensor. By placing them close together, the temperature values ​​they obtain are less different, thus avoiding errors in the control process.

[0018] In some technical solutions, optionally, the bottom surface of the base is used as the projection surface, and the temperature detection element and the temperature switch are projected onto the projection surface, with the projection of the temperature detection element being separate from the projection of the temperature switch.

[0019] The projection area of ​​the temperature sensing element does not coincide with the projection of the temperature switch to avoid interference with the wiring of the temperature switch and to avoid affecting the deformation and recovery of the temperature switch.

[0020] In some technical solutions, the temperature sensing element and the temperature switch are optionally located at the bottom of the heating plate.

[0021] Both the temperature sensor and the temperature switch occupy the bottom space of the heating plate, making it easy to place the temperature sensor and the temperature switch close together.

[0022] In some technical solutions, optionally, the water control assembly further includes: a valve body shell connected to the heating plate, 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.

[0023] 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.

[0024] 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.

[0025] In some technical solutions, the temperature switch may optionally include: a deformation part connected to the heating plate, which deforms when the temperature of the deformation part is greater than or equal to a second set temperature T2, and remains in its original state when the temperature of the deformation part is less than a third set temperature T3; and a pushing part connected to the deformation part, which pushes the push rod when the deformation part deforms.

[0026] The pushing part comes into contact with the deforming part, and the pushing part overlaps in the deforming part at a position where deformation can occur. The deforming part is used to push the pushing part, and when the deforming part deforms, the pushing part can follow the deformation of the deforming part to move.

[0027] One end of the push rod contacts the pushing part, and the other end of the push rod contacts the elastic seal. For example, the pushing part can be a strip plate, with both ends connected to the deformable part and the push rod respectively, so that the pushing part can push the push rod to move when it follows the deformable part, thereby enabling the push rod to push the elastic seal to move, thus opening or closing the passage between the water supply end and the steam generator.

[0028] Thus, with the deformation section and the push rod staggered, the linkage between the two can be achieved through the pushing section, which facilitates the rational layout of the internal structure of the cooking equipment.

[0029] In some technical solutions, optionally, the water inlet pipe includes a bottom wall with a recessed portion and the water inlet is located on the recessed portion.

[0030] The bottom wall of the water inlet pipe is defined as the pipe bottom wall. A recessed section is located on this bottom wall, lower than other parts of the pipe. The water inlet is situated on the inner wall of this recessed section. Because of its recessed structure, the recess is positioned at a lower point within the pipe bottom wall, allowing water to flow easily towards it and ensuring smooth water intake.

[0031] In some technical solutions, optionally, the first end of the water inlet pipe is used to connect to the water inlet, and the water inlet pipe is inclined towards the water inlet from the second end of the water inlet pipe to the first end of the water inlet pipe.

[0032] Incline the water inlet pipe toward the water inlet hole so that the water inside the pipe can gather toward the inlet, improving the smoothness of water intake.

[0033] Secondly, this utility model proposes a cooking device, including: a base assembly as described in the first aspect.

Detailed Implementation

[0048] 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.

[0049] 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.

[0050] The following reference Figures 1 to 10 This invention describes a base assembly and cooking device provided according to some embodiments of the present invention.

[0051] Combination Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, in some embodiments of this utility model, a base assembly 100 is provided for a cooking device having a cooking cavity 310. The base assembly 100 includes a base 110, a steam generating assembly 120, a temperature detection element 140, and a water control assembly 130. 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 within the steam generator 122 to provide steam to the cooking cavity 310. The temperature detection element 140 is connected to the steam generating assembly 120 and detects the temperature of the heating plate 121. When the temperature of the heating plate 121 is greater than or equal to a first set temperature T1, the heating plate 121 is controlled to stop heating; when the temperature of the heating plate 121 is less than the first set temperature T1, the heating plate 121 is controlled to start heating. The water control component 130 is located inside the base 110. The water control component 130 includes a temperature switch 131. The temperature of the temperature switch 131 changes with the temperature of the heating plate 121. The temperature switch 131 is arranged adjacent to the temperature detection element 140. When the temperature of the temperature switch 131 is greater than or equal to the second set temperature T2, the water control component 130 is used to connect the water supply end 200 with the steam generator 122. When the temperature of the temperature switch 131 is less than the third set temperature T3, the water control component 130 closes the passage between the water supply end 200 and the steam generator 122, where T2 > T1 and T2 ≥ T3.

[0052] The steam generating assembly 120 includes a heating plate 121 and a steam generator 122. Water from the water supply end 200 can enter the steam generator 122 through a pipe. The heating plate 121 heats the water to produce steam. The cooking equipment has a cooking chamber 310, and the steam in the steam generator 122 can heat the food inside.

[0053] 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 the second set temperature T2, the passage between the water supply end 200 and the steam generating component 122 is opened, allowing water from the water supply end 200 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 temperature switch 131 is lower than the third set temperature T3, 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, heating plate 121 can continue to heat up until the temperature of temperature switch 131 reaches the second set temperature T2 again. Then, water control component 130 reopens the passage between water supply end 200 and steam generator 122, and repeats the above process.

[0054] 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 heating plate 121, 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 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.

[0055] During the heating process of heating plate 121, if there is water in steam generator 122, the temperature of heating plate 121 will rise to a certain value and remain basically unchanged. If the temperature of heating plate 121 continues to rise from a stable temperature, it indicates that the water in steam generator 122 has boiled away. When the temperature of heating plate 121 reaches the first set temperature T1, heating plate 121 is stopped. That is, the first set temperature T1 is the set temperature of heating plate 121. By controlling heating plate 121 to stop heating, prolonged dry burning of heating plate 121 can be avoided, preventing damage to heating plate 121 and related circuits due to high temperature. After water enters steam generator 122, the temperature inside heating plate 121 decreases. After the temperature of heating plate 121 decreases, heating plate 121 is controlled to continue heating.

[0056] In this design, the temperature switch 131 and the temperature sensor 140 are arranged adjacent to each other, meaning no other components are placed between them. This shortens the installation distance between the temperature switch 131 and the temperature sensor 140. Placing the temperature sensor 140 near the temperature switch 131 allows for better control of the temperature of the temperature switch 131 based on the temperature of the sensor 140. Since both the temperature sensor 140 and the temperature switch 131 are affected by the temperature of the heating plate, their close proximity minimizes the difference in their temperature readings, thus avoiding errors in the control process. Changes in the size or power of the steam generating assembly 120 will not affect the normal operation of the system.

[0057] The second set temperature T2 is greater than 100°C. For example, the second set temperature T2 is 110°C or 120°C.

[0058] Combination Figure 3 , Figure 9 and Figure 10 As shown, in some embodiments, optionally, the steam generating assembly 120 further includes a heating element 123 connected to the heating plate 121, the heating element 123 being used to heat the heating plate 121, and the temperature switch 131 and the temperature detection element 140 being located on the same side of the heating element 123.

[0059] Heating element 123 heats heating plate 121. After the temperature of heating plate 121 rises, it can heat the water in steam generator 122. The heat from heating element 123 affects temperature switch 131 and temperature sensor 140. By placing temperature switch 131 and temperature sensor 140 on the same side of heating element 123, the effects of heating element 123 on temperature switch 131 and temperature sensor 140 are basically the same, thereby improving the synchronization of temperature response of temperature switch 131 and temperature sensor 140.

[0060] like Figure 9 As shown, in some embodiments, optionally, the heating element 123 includes a heating part 124 and a wiring part 125, the wiring part 125 is connected to the heating part 124, and the minimum distance between the heating part 124 and the temperature detection element 140 is less than the minimum distance between the wiring part 125 and the temperature detection element 140.

[0061] The wiring section 125 is used to connect to external wiring, and the heating section 124 is used to generate heat. Therefore, in the heating element 123, the heating section 124 is the main heat source. In this design, the distance between the temperature detection element 140 and the heating section 124 is limited, that is, the temperature detection element 140 is close to the personnel area of ​​the heating element, so that the temperature detection element 140 can detect temperature changes more quickly and thus respond quickly.

[0062] like Figure 10 As shown, in some embodiments, optionally, the distance between the temperature sensing element 140 and the temperature switch 131 is L, where L satisfies 0mm≤L≤1cm.

[0063] In this design, the distance between the temperature sensor 140 and the temperature switch 131 is limited to less than or equal to 1 cm. Therefore, the temperature sensor 140 and the temperature switch 131 are close to each other. This allows for better control of the temperature of the temperature switch 131 based on the temperature of the temperature sensor 140. By placing the two close together, the temperature values ​​obtained by the two devices are less different, which helps to avoid errors in the control process.

[0064] In some embodiments, optionally, the bottom surface 111 of the base 110 is used as the projection surface, and the temperature detection element 140 and the temperature switch 131 are projected onto the projection surface, and the projection of the temperature detection element 140 is separate from the projection of the temperature switch 131.

[0065] The projection area of ​​the temperature sensing element 140 does not coincide with the projection of the temperature switch 131, so as to avoid interference with the wiring of the temperature switch 131 and to avoid affecting the deformation and recovery of the temperature switch 131.

[0066] In some embodiments, the temperature sensor 140 and the temperature switch 131 are both located at the bottom of the heating plate 121.

[0067] The temperature sensor 140 and the temperature switch 131 both occupy the bottom space of the heating plate 121, which makes it easy to place the temperature sensor 140 and the temperature switch 131 close together.

[0068] In some embodiments, optionally, with the bottom surface 111 of the base 110 as the projection surface, the projections of the temperature switch 131 and the temperature detection element 140 are spaced apart from the projection of the heating element 123, and the projections of the temperature switch 131 and the temperature detection element 140 are located outside the projection of the heating element 123.

[0069] The temperature of the temperature switch 131 changes with the temperature of the heating plate 121. The temperature detection element 140 is used to detect the temperature of the heating plate 121. By setting the temperature switch 131 and the temperature detection element 140 at intervals from the heating element 123, the influence of the heating plate 121 on the temperature switch 131 and the temperature detection element 140 can be reduced.

[0070] The temperature switch 131 and the temperature sensor 140 are positioned outside the heating element 123 to prevent the heating element 123 from surrounding the temperature switch 131 and the temperature sensor 140. This also reduces the influence of the heating plate 121 on the temperature switch 131 and the temperature sensor 140.

[0071] 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 132, an elastic seal 138, and a push rod 139. The valve body housing 132 is connected to the heating plate 121. 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. 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.

[0072] 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.

[0073] 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.

[0074] For example, the resilient seal 138 is a rubber resilient or a silicone resilient.

[0075] The water inlet cavity 137 and the steam generator 122 are connected by a pipe.

[0076] The valve body housing 132 includes a water valve upper cover 133 and a water valve lower cover 134, which are detachably connected.

[0077] In some embodiments, the valve body housing 132 and the temperature switch 131 are both connected to the heating plate 121.

[0078] 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.

[0079] Combination Figure 4 , Figure 6 , Figure 7 and Figure 8 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 second set temperature T2, the deformable portion 1311 deforms. When the temperature of the deformable portion 1311 is less than a third set temperature T3, 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] Figure 7 In the middle, the deformable part 1311 did not deform and did not push the pushing part 1312. Figure 8 In the middle, the deformable part 1311 deforms and pushes the pushing part 1312. Figure 8 The left side of the central propulsion unit 1312 curves upward.

[0084] 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.

[0085] Combination Figure 4 and Figure 5 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.

[0086] 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.

[0087] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, the first end of the water inlet pipe 135 is used to connect 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.

[0088] 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.

[0089] In an embodiment of this utility model, a cooking device is proposed, including a base assembly as described in any of the above embodiments, and can achieve the same technical effect, which will not be repeated here.

[0090] For example, the cooking equipment can be a steam stew pot, a steam cooking machine, etc.

[0091] 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.

[0092] 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.

[0093] 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.
