Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and more specifically, to a base assembly and a cooking device. Background Technology

[0002] Steam cookers heat the stew pot and the food inside using steam. To ensure cooking speed, the temperature inside the cooking chamber needs to rise rapidly and remain stable throughout the cooking process, which requires a stable supply of water to the heating element and continuous steam generation.

[0003] During the cooking process, users need to manually control the water supply to and from the heating element, requiring them to stay by the steam cooker, which is inconvenient for users. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, in a first aspect, the present invention proposes a base assembly for a cooking device having a cooking cavity. The base assembly includes: 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 having a heating surface for heating water within the steam generating element to supply steam to the cooking cavity, the heating surface including a first part and a second part, the first part being higher than the second part relative to the bottom surface of the base; and a water control assembly disposed within the base, the water control assembly including a temperature switch, the temperature of which 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. In a direction perpendicular to the bottom surface, at least a portion of the temperature switch is disposed opposite to the first portion.

[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 first set temperature T1, the passage between the water supply and the steam generator is opened, allowing water from the supply end to enter the steam generator. In this state, the 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 T2, 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 T1 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] In order to ensure that the water intake-boiling-re-water intake process can proceed smoothly, the temperature switch usually only rises to the first set temperature after the water in the heating element has boiled dry. This is because the actual temperature of the temperature switch during the boiling stage must be lower than the first set temperature to avoid the water from the previous water not being boiled dry before water is added, which would cause the water in the steam generator to increase and overflow. For this reason, there is a certain amount of time between the water boiling dry and the temperature switch reaching the first set temperature, and the water supply end adding water to the steam generator. This will cause several problems: (1) No steam is generated during this period, that is, the steam is discontinuous, which will affect the cooking of the food. Effects; (2) The steam generating component is also in a dry-burning state during this period, and the overall temperature is high, which affects the service life. If a coating is used, it will affect the reliability of the coating; (3) During this period, the steam generating component will rise to a high temperature. In the early stage of water inlet, obvious modal boiling will occur. The steam generating component and water heat transfer is slow. On the one hand, the violent boiling of water at this time will generate noise, and hot water may splash out and injure people. On the other hand, because the temperature of the steam generating component cannot be reduced quickly, the steam generating component cannot be restored to work quickly due to the influence of thermistors or temperature controllers and other protective devices, which further prolongs the steam interruption time.

[0010] The top surface of the heating plate is the heating surface, which is used to heat the water in the steam generator. The height of different positions on the heating surface is different. The first part of the heating surface is higher than the second part. The temperature switch is set opposite to the first part, that is, the installation position of the temperature switch corresponds to the first part.

[0011] As the water inside the steam generator gradually evaporates, the liquid level inside the steam generator gradually decreases. The water at the higher position on the heating surface evaporates first. Taking the first and second parts as examples, when the amount of water in the steam generator is small, the first part is higher, so the water in the first part evaporates first. At this time, the first part is in a dry-burning state, and its temperature begins to rise. Since the temperature switch is opposite to the first part, its temperature also rises, allowing it to reach the first set temperature. During this process, water in the second part continues to be heated. Through this solution, when water begins to enter the steam generator, the second part heats the water and generates steam, which helps to achieve uninterrupted steam throughout the entire operation, greatly shortening the dry-burning time of the entire steam generator assembly, avoiding or shortening the steam interval problem, reducing the maximum temperature reached and the area of ​​dry burning during the dry-burning stage of the steam generator assembly, and improving the reliability of the steam generator assembly.

[0012] In addition, the base assembly according to the above-described technical solution provided by this utility model may also have the following additional technical features:

[0013] In some technical solutions, the temperature switch is optionally staggered from the second part in a direction perpendicular to the bottom surface.

[0014] The temperature switch is installed opposite to the first part, and its installation position is staggered from the second part. Therefore, the temperature of the temperature switch is affected by the first part but not so much by the second part. After the water in the first part boils dry, there is still water in the second part. This allows the temperature switch to avoid the lower part of the heating surface, meaning it can avoid the lower-temperature areas on the heating surface. When dry burning occurs at a higher part of the heating surface, the temperature switch can respond quickly, thereby rapidly reaching the first set temperature and shortening the dry burning time of the heating surface.

[0015] In some technical solutions, optionally, the second part is a groove, with the bottom surface of the base as a reference, and the first part is higher than the bottom wall of the groove.

[0016] In this scheme, grooves are provided on the heating surface, and the position on the heating surface without grooves is higher than the bottom wall of the groove. The position on the heating surface without grooves is defined as the first part, and the position on the heating surface with grooves is defined as the second part.

[0017] As the water inside the steam generator evaporates, the water in the area without the groove on the heating surface dries up first, while water in the groove is still being heated. The temperature switch is installed in the area without the groove on the heating surface. Therefore, when the water in the area without the groove on the heating surface dries up, the temperature of the temperature switch will start to rise. During the temperature rise process, steam is still generated inside the steam generator, reducing the dry burning time of the heating surface and improving the reliability of the steam generating assembly.

[0018] In some technical solutions, the first set temperature T1 is optionally positively correlated with the volume of the groove.

[0019] The larger the volume of the groove, the greater its water storage capacity. After the water in the first part boils dry, the greater the water storage capacity of the groove, the longer it takes for all the water on the heating surface to boil dry. Therefore, for products with a large groove volume, when selecting the temperature switch model, it is necessary to choose a temperature switch with a larger deformation temperature. That is, after the water in the first part boils dry, the greater the water storage capacity of the groove, the longer it takes for the temperature switch to reach its deformation temperature. This ensures that some of the water in the groove can evaporate, preventing the temperature switch from deforming just as the water in the first part boils dry. This also prevents frequent water ingress into the steam generator, ensuring a continuous steam generation time.

[0020] In some technical solutions, optionally, the first part is a boss, with the top of the boss higher than the second part, based on the bottom surface of the base.

[0021] In this solution, a boss is provided on the heating surface. The boss is higher than other positions on the heating surface. The position of the boss on the heating surface is defined as the first part, and the position of the boss on the heating surface is defined as the second part.

[0022] As the water inside the steam generator evaporates, the water on the boss is dried up first. At this time, water is still being heated in the areas of the heating surface without bosses. The temperature switch is installed at the location of the boss. Therefore, when the water on the boss is dried up, the temperature of the temperature switch will start to rise. During the temperature switch heating process, steam is still generated inside the steam generator, reducing the dry burning time of the heating surface and improving the reliability of the steam generating assembly.

[0023] In some technical solutions, the heating surface can optionally be an inclined plane, with the height of the inclined plane decreasing from the bottom surface of the base to the second part.

[0024] From the first section to the second, the heating surface is an inclined plane with a gradually decreasing height. As the water inside the steam generator evaporates, the water at the higher position on the inclined plane is dried up first, while water at the lower position on the inclined plane is still being heated. The temperature switch is installed at the higher position on the inclined plane. Therefore, when the water at the higher position on the inclined plane is dried up, the temperature of the temperature switch will start to rise. During the temperature switch's heating process, steam is still generated inside the steam generator, reducing the dry-burning time of the heating surface and improving the reliability of the steam generating assembly.

[0025] In some technical solutions, the steam generating assembly may optionally include a heating element for heating the heating plate, with the bottom surface of the base serving as the projection surface for the heating element and the second part, and at least a portion of the projection of the second part being located within the projection range of the heating element.

[0026] The projection of the second part falls within the projection range of the heating element. The relative position of the second part and the heating element allows the heating element to be distributed circumferentially along the second part, which is beneficial to improving the heating uniformity of the second part.

[0027] In some technical solutions, optionally, the bottom surface of the base is used as the projection surface for the heating element and the temperature switch, and the projection of the temperature switch is located outside the projection range of the heating element.

[0028] The temperature switch is attached to the heating plate, but it needs to be spaced apart from the heating element. The temperature change of the temperature switch should be mainly affected by the temperature of the heating plate, which is used to indicate whether there is water in the steam generator. Therefore, by spaced apart from the heating element, the temperature influence of the heating element on the temperature switch can be reduced, thereby ensuring that the water control component accurately controls the timing of water inlet and water stoppage.

[0029] In some technical solutions, optionally, the distance between the edge of the heating surface and the heating element is greater than the distance between the edge of the heating surface and the temperature switch.

[0030] The distance between the edge of the heating surface and the heating element is relatively large, while the distance between the edge of the heating surface and the temperature switch is relatively small. Therefore, the temperature switch is located outside the heating element, that is, the temperature switch is not set in the area enclosed by the heating element. This can reduce the temperature influence of the heating element on the temperature switch, thereby ensuring that the water control component accurately controls the timing of water inlet and water stoppage.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] Secondly, this utility model proposes a base assembly for a cooking device. The cooking device has a cooking cavity. The base assembly includes: 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 having a heating surface for heating water within the steam generating element to provide steam to the cooking cavity, the heating surface including a first part and a second part; 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. 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. In a direction perpendicular to the bottom surface, at least a portion of the temperature switch is positioned opposite to the first part. In a first state, the difference between the highest temperature of the first part and the highest temperature of the second part is less than or equal to a preset value T3. In a second state, the highest temperature of the first part is higher than the highest temperature of the second part, and the difference between the highest temperature of the first part and the highest temperature of the second part is greater than the preset value T3.

[0035] 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.

[0036] 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 T1, the passage between the water supply and the steam generator is opened, allowing water from the supply end to enter the steam generator. In this state, the 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 T2, 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 T1 again. Then, the water control component reopens the passage between the water supply and the steam generator, repeating the above process.

[0037] 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.

[0038] In order to ensure that the water intake-boiling-re-water intake process can proceed smoothly, the temperature switch usually only rises to the first set temperature after the water in the heating element has boiled dry. This is because the actual temperature of the temperature switch during the boiling stage must be lower than the first set temperature to avoid the water from the previous water not being boiled dry before water is added, which would cause the water in the steam generator to increase and overflow. For this reason, there is a certain amount of time between the water boiling dry and the temperature switch reaching the first set temperature, and the water supply end adding water to the steam generator. This will cause several problems: (1) No steam is generated during this period, that is, the steam is discontinuous, which will affect the cooking of the food. Effects; (2) The steam generating component is also in a dry-burning state during this period, and the overall temperature is high, which affects the service life. If a coating is used, it will affect the reliability of the coating; (3) During this period, the steam generating component will rise to a high temperature. In the early stage of water inlet, obvious modal boiling will occur. The steam generating component and water heat transfer is slow. On the one hand, the violent boiling of water at this time will generate noise, and hot water may splash out and injure people. On the other hand, because the temperature of the steam generating component cannot be reduced quickly, the steam generating component cannot be restored to work quickly due to the influence of thermistors or temperature controllers and other protective devices, which further prolongs the steam interruption time.

[0039] The top surface of the heating plate is the heating surface, used to heat the water inside the steam generator. The heating surface is divided into two parts: a first part and a second part. Throughout the cooking process, the heating plate exists in a first state and a second state. In the first state, the difference between the highest temperature of the first part and the highest temperature of the second part is less than or equal to a preset value. The highest temperature of the first part may be higher than the highest temperature of the second part, and vice versa. However, the difference between the highest temperatures of the first part and the second part will not exceed the preset value. That is, the highest temperatures of the first part and the second part can be basically the same or fluctuate within a certain range. Therefore, in the first state, both the first and second parts are covered with water, and the water on both parts does not boil dry.

[0040] In the second state, if the highest temperature of the first part is higher than the highest temperature of the second part, and the difference between the highest temperatures of the first and second parts is greater than the preset value T3, it indicates that at least a portion of the first part is in a dry-burning state, meaning the water in the first part dries up before the water in the second part. Since the temperature switch is opposite to the first part, its temperature also rises, allowing it to reach the first set temperature. During this process, water covers the second part, and water continues to be heated on the second part. This solution allows the second part to heat the water and generate steam when water begins to enter the steam generator, helping to achieve uninterrupted steam throughout the entire operation. This significantly shortens the dry-burning time of the entire steam generator assembly, avoids or reduces steam interval problems, lowers the highest temperature reached during the dry-burning stage of the steam generator assembly, and reduces the area affected by dry burning, thus improving the reliability of the steam generator assembly.

[0041] In some embodiments, the preset value T3 may optionally satisfy: 5℃≤T3≤15℃.

[0042] In the first state, the difference between the highest temperature of the first part and the highest temperature of the second part satisfies: 5℃≤T3≤15℃. Under this condition, the difference between the highest temperature of the first part and the highest temperature of the second part is small, indicating that the water in both the first and second parts has not been boiled dry.

Detailed Implementation

[0061] 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.

[0062] 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.

[0063] The following reference Figures 1 to 13 This invention describes a base assembly and cooking device provided according to some embodiments of the present invention.

[0064] Combination Figure 1 , Figure 2 , Figure 3 and Figure 7 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, and a water control assembly 130. Both the steam generating assembly 120 and the water control assembly 130 are disposed within the base 110. The steam generating assembly 120 includes a heating plate 121 and a steam generating element 122. The heating plate 121 has a heating surface 124, which heats the water within the steam generating element 122 to provide steam to the cooking cavity 310. The heating surface 124 includes a first portion 125 and a second portion 126. With the bottom surface 111 of the base 110 as a reference, the first portion 125 is higher than the second portion 126. The water control assembly 130 includes a temperature switch 131. The temperature of the temperature switch 131 changes with the temperature of the heating plate 121. When the temperature of the temperature switch 131 is greater than or equal to the first set temperature T1, the water control assembly 130 is used to connect the water supply end 200 to the steam generator 122. In the direction perpendicular to the bottom surface 111, at least a portion of the temperature switch 131 is arranged opposite to the first portion 125.

[0065] 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.

[0066] 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 first set temperature T1, 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 the temperature switch 131 is lower than the second set temperature T2, the water control component 130 closes the passage between the water supply end 200 and the steam generator 122, and the water from the water supply end 200 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 T1 again. Then, the water control component 130 reopens the passage between the water supply end 200 and the steam generator 122, and repeats the above process.

[0067] 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.

[0068] In order to ensure that the water intake-boiling-re-water intake process can proceed smoothly, the temperature switch 131 usually only rises to the first set temperature after the water in the heating element has boiled dry. This is because the actual temperature of the temperature switch 131 during the boiling stage needs to be lower than the first set temperature to avoid the previous water not being boiled dry before water is added, which would cause the water in the steam generator 122 to increase and overflow. For this reason, there is a certain amount of time between the water boiling dry and the temperature switch 131 reaching the first set temperature, and the water supply end 200 adding water to the steam generator 122. This will cause several problems: (1) No steam is generated during this time, that is, the steam is discontinuous, which will affect the food. Cooking effect; (2) During this period, the steam generating component 120 is also in a dry-burning state, with a high overall temperature, which affects the service life. If a coating is used, it will affect the reliability of the coating; (3) During this period, the steam generating component 120 will rise to a high temperature. In the early stage of water intake, obvious modal boiling will occur. The steam generating component 120 and water heat transfer is slow. On the one hand, the violent boiling of water at this time will generate noise, and hot water may splash out and injure people. On the other hand, since the temperature of the steam generating component 120 cannot be reduced quickly, the steam generating component 120 cannot be restored to work quickly due to the influence of thermistors or temperature controllers and other protective devices, which further prolongs the steam interruption time.

[0069] The top surface of the heating plate 121 is the heating surface 124, which is used to heat the water in the steam generator 122. The height of different positions on the heating surface 124 is different. The first part 125 of the heating surface 124 is higher than the second part 126. The temperature switch 131 is set opposite to the first part 125, that is, the installation position of the temperature switch 131 corresponds to the first part 125.

[0070] As the water in the steam generator 122 gradually evaporates, the liquid level in the steam generator 122 gradually decreases. The water at the higher position on the heating surface 124 evaporates first. Taking the first part 125 and the second part 126 as examples, when the amount of water in the steam generator 122 is small, the height of the first part 125 is higher, so the water on the first part 125 evaporates first. At this time, the first part 125 is in a dry-burning state, and the temperature of the first part 125 begins to rise. Since the temperature switch 131 is opposite to the first part 125, the temperature of the temperature switch 131 will also rise, so that the temperature of the temperature switch 131 can reach the first set temperature. During this process, water on the second part 126 is still being heated continuously. With this solution, when water begins to enter the steam generator 122, the second part 126 heats the water and generates steam, which helps to achieve uninterrupted steam throughout the entire working process, greatly shortens the dry burning time of the entire steam generator assembly 120, avoids the problem of steam interval or shortens the steam interval time, and reduces the maximum temperature reached and the area of ​​dry burning of the steam generator assembly 120 during the dry burning stage, thereby improving the reliability of the steam generator assembly 120.

[0071] For example, the first set temperature can be greater than 100 degrees Celsius, that is, the first set temperature is greater than the vaporization temperature of water.

[0072] In some embodiments, optionally, both the first portion 125 and the second portion 126 are used to heat water to generate steam.

[0073] Combination Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments, the temperature switch 131 is optionally misaligned with the second portion 126 in a direction perpendicular to the bottom surface 111.

[0074] The temperature switch 131 is installed opposite to the first part 125, and its installation position is staggered from that of the second part 126. Therefore, the temperature of the temperature switch 131 is affected by the first part 125, but not so much by the second part 126. After the water on the first part 125 has boiled dry, there is still water on the second part 126. This allows the temperature switch 131 to avoid the lower position on the heating surface 124, meaning the temperature switch 131 can avoid the lower-temperature position on the heating surface 124. When dry burning occurs on the higher position of the heating surface 124, the temperature switch 131 can respond quickly, thereby rapidly reaching the first set temperature and shortening the dry burning time of the heating surface 124.

[0075] like Figure 4As shown, in some embodiments, optionally, the second portion 126 includes a groove 127, with the bottom surface 111 of the base 110 as a reference, and the first portion 125 is higher than the bottom wall of the groove 127.

[0076] In this design, the heating surface 124 is provided with a groove 127. The position on the heating surface 124 without the groove 127 is higher than the bottom wall of the groove 127. The position on the heating surface 124 without the groove 127 is defined as the first part 125, and the position on the heating surface 124 with the groove 127 is defined as the second part 126.

[0077] As the water in the steam generator 122 evaporates, the water in the area without the groove 127 on the heating surface 124 is dried up first, while water in the groove 127 is still being heated. The temperature switch 131 is installed at the position in the heating surface 124 where the groove 127 is not provided. Therefore, when the water in the area without the groove 127 on the heating surface 124 is dried up, the temperature of the temperature switch 131 will start to rise. During the heating process of the temperature switch 131, steam is still generated in the steam generator 122, reducing the dry burning time of the heating surface 124 and improving the reliability of the steam generator assembly 120.

[0078] In some embodiments, the first set temperature T1 is optionally positively correlated with the volume of the groove 127.

[0079] The larger the volume of groove 127, the greater its water storage capacity. After the water in the first part 125 boils dry, the greater the water storage capacity of groove 127, the longer it takes for all the water on the heating surface to boil dry. Therefore, for products with a larger groove 127 volume, when selecting the model of temperature switch 131, it is necessary to select a temperature switch 131 with a larger deformation temperature. That is, after the water in the first part 125 boils dry, the greater the water storage capacity of groove 127, the longer it takes for temperature switch 131 to reach its deformation temperature. This ensures that some of the water in groove 127 can evaporate, preventing the temperature of temperature switch 131 from deforming just as the water in the first part 125 boils dry. This also prevents frequent water ingress into the steam generator, ensuring the continuous generation of steam.

[0080] like Figure 5 As shown, in some embodiments, optionally, the first portion 125 includes a boss 128 with the top of the boss 128 being higher than the second portion 126, with the bottom surface 111 of the base 110 as a reference.

[0081] In this design, a boss 128 is provided on the heating surface 124. The boss 128 is higher than other positions on the heating surface 124. The position of the boss 128 on the heating surface 124 is limited to the first part 125, and the position of the boss 128 on the heating surface 124 is limited to the second part 126.

[0082] As the water inside the steam generator 122 evaporates, the water on the boss 128 is dried up first. At this time, water is still being heated in the area of ​​the heating surface 124 where the boss 128 is not located. The installation position of the temperature switch 131 corresponds to the position of the boss 128. Therefore, when the water on the boss 128 is dried up, the temperature of the temperature switch 131 will start to rise. During the heating process of the temperature switch 131, steam is still generated inside the steam generator 122, reducing the dry burning time of the heating surface 124 and improving the reliability of the steam generator assembly 120.

[0083] In some embodiments, the temperature switch 131 may be disposed below the boss 128.

[0084] The temperature switch 131 is positioned near the boss 128 so that the water on the heating surface 124 adjacent to the temperature switch 131 is dried first, and the temperature switch 131 can start to operate before all the water on the heating surface 124 is dried.

[0085] like Figure 6 As shown, in some embodiments, optionally, the heating surface 124 includes a ramp 129 from a first portion 125 to a second portion 126, with the height of the ramp 129 decreasing relative to the bottom surface 111 of the base 110.

[0086] From the first part 125 to the second part 126, the heating surface 124 is an inclined plane 129 with a gradually decreasing height. As the water in the steam generator 122 evaporates, the water at the higher position on the inclined plane 129 is dried up first. At this time, water at the lower position on the inclined plane 129 is still being heated. The installation position of the temperature switch 131 corresponds to the higher position on the inclined plane 129. Therefore, when the water at the higher position on the inclined plane 129 is dried up, the temperature of the temperature switch 131 will start to rise. During the heating process of the temperature switch 131, steam is still generated in the steam generator 122, reducing the dry burning time of the heating surface 124 and improving the reliability of the steam generator assembly 120.

[0087] Combination Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments, optionally, the steam generating assembly 120 further includes a heating element 123 for heating the heating plate 121, with the bottom surface 111 of the base 110 as the projection surface for the projection of the heating element 123 and the second part 126, and at least a portion of the projection of the second part 126 is located within the projection range of the heating element 123.

[0088] The projection of the second part 126 falls within the projection range of the heating element 123. The relative positions of the second part 126 and the heating element 123 allow the heating element 123 to be distributed circumferentially along the second part 126, which is beneficial to improving the heating uniformity of the second part 126.

[0089] In some embodiments, optionally, the bottom surface 111 of the base 110 is used as the projection surface for the projection of the heating element 123 and the temperature switch 131, and the projection of the temperature switch 131 is located outside the projection range of the heating element 123.

[0090] Temperature switch 131 is attached to heating plate 121, but temperature switch 131 needs to be spaced apart from heating element 123. The temperature change of temperature switch 131 should be mainly affected by the temperature of heating plate 121. The temperature change of heating plate 121 is used to detect whether there is water in steam generator 122. Therefore, by spaced apart temperature switch 131 and heating element 123, the temperature influence of heating element 123 on temperature switch 131 can be reduced, thereby ensuring that water control component 130 accurately controls the timing of water inlet and water stoppage.

[0091] like Figure 7 As shown, in some embodiments, optionally, the distance between the edge of the heating surface 124 and the heating element 123 is greater than the distance between the edge of the heating surface 124 and the temperature switch 131.

[0092] The distance between the edge of the heating surface 124 and the heating element 123 is relatively large, while the distance between the edge of the heating surface 124 and the temperature switch 131 is relatively small. Therefore, the temperature switch 131 is located outside the heating element 123, that is, the temperature switch 131 is not set in the area enclosed by the heating element 123. This can reduce the temperature influence of the heating element 123 on the temperature switch 131, thereby ensuring that the water control assembly 130 accurately controls the timing of water inlet and water stoppage.

[0093] Temperature switch 131 is attached to heating plate 121, so that the temperature of temperature switch 131 is close to the temperature of heating plate 121. In this design, the assembly position of temperature switch 131 is set near heating element 123. In this way, during the heating process, the temperature of heating element 123 can be transferred to temperature switch 131 more quickly, so that temperature switch 131 can respond more quickly and its temperature can reach the first set temperature T1 more easily, ensuring that steam generator 122 can be filled with water in time.

[0094] Combination Figure 2 , Figure 8 , Figure 9 and Figure 10As 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 housing 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 housing 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.

[0095] 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.

[0096] 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.

[0097] The valve body housing 132 includes a water valve upper cover 133 and a water valve lower cover 134, with an elastic seal 138 installed between the water valve upper cover 133 and the water valve lower cover 134. The water valve lower cover 134 is mounted on the heating plate 121. The elastic seal 138 is fixed to the water valve lower cover 134, and the water inlet is located on the water valve upper cover 133. When the push rod 139 pushes the elastic seal 138, a portion of the elastic seal 138 rises, thereby opening the water inlet 136.

[0098] For example, the resilient seal 138 is a rubber resilient or a silicone resilient.

[0099] In some embodiments, the valve body housing 132 and the temperature switch 131 are both connected to the heating plate 121.

[0100] 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.

[0101] Combination Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, optionally, the temperature switch 131 includes a deformable portion 1311 and a pushing portion 1312. The deformable portion 1311 is connected to the heating plate 121. When the temperature of the deformable portion 1311 is greater than or equal to a first set temperature T1, the deformable portion 1311 deforms. When the temperature of the deformable portion 1311 is less than a second set temperature T2, the deformable portion 1311 remains in its original state. The pushing portion 1312 is connected to the deformable portion 1311. When the deformable portion 1311 deforms, the pushing portion 1312 pushes the push rod 139.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] Figure 12In the middle, the deformable part 1311 did not deform and did not push the pushing part 1312. Figure 13 In the middle, the deformable part 1311 deforms and pushes the pushing part 1312. Figure 13 The left side of the central propulsion unit 1312 curves upward.

[0106] 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.

[0107] Combination Figure 8 and Figure 9 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.

[0108] 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.

[0109] like Figure 8 As shown, in some embodiments, optionally, the first end of the water inlet pipe 135 is connected to the water inlet 136, and the water inlet pipe 135 is inclined toward the water inlet 136 from the second end of the water inlet pipe 135 to the first end of the water inlet pipe 135.

[0110] 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.

[0111] In an embodiment 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, 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 generating element 122. The heating plate 121 has a heating surface 124 for heating water within the steam generating element 122 to provide steam to the cooking cavity 310. The heating surface 124 includes a first portion 125 and a second portion 126. A water control assembly 130 is disposed 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 plate 121. When the temperature of the temperature switch 131 is greater than or equal to a first set temperature T1, the water control assembly 130 connects the water supply end to the steam generator 122. In a direction perpendicular to the bottom surface 111, at least a portion of the temperature switch 131 is positioned opposite to the first portion 125. In a first state, the difference between the highest temperature of the first portion 125 and the highest temperature of the second portion 126 is less than or equal to a preset value T3. In a second state, the highest temperature of the first portion 125 is higher than the highest temperature of the second portion 126, and the difference between the highest temperatures of the first portion 125 and the second portion 126 is greater than the preset value T3.

[0112] The steam generating assembly 120 includes a heating plate 121 and a steam generator 122. Water from the water supply end can enter the steam generator 122 through a pipe. The heating plate 121 heats the water to turn it into steam. The cooking equipment has a cooking chamber 310, and the steam in the steam generator 122 can heat the food inside the cooking chamber.

[0113] 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 first set temperature T1, the passage between the water supply end and the steam generating component 122 is opened, allowing water from the water supply end 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 second set temperature T2, water control component 130 closes the passage between water supply end and steam generator 122, and water from the water supply end stops entering the steam generator 122. Under these circumstances, heating plate 121 can continue to heat up until the temperature of temperature switch 131 reaches the first set temperature T1 again. Then, water control component 130 reopens the passage between water supply end and steam generator 122, and repeats the above process.

[0114] Thus, the water control component 130 can open or close the passage between the water supply end 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 allows the cooking equipment 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. During the cooking process, the user does not need to stay 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.

[0115] In order to ensure that the water intake-boiling-re-water intake process can proceed smoothly, the temperature switch 131 usually only rises to the first set temperature after the water in the heating element has boiled dry. This is because the actual temperature of the temperature switch 131 during the boiling stage needs to be lower than the first set temperature to avoid the water from the previous water not being boiled dry before water is added, which would cause the water in the steam generator 122 to increase and overflow. For this reason, there is a certain amount of time between the water boiling dry and the temperature switch 131 reaching the first set temperature and the water supply end adding water to the steam generator 122. This will cause several problems: (1) No steam is generated during this period, that is, the steam is discontinuous, which will affect the cooking of the food. Effects; (2) During this period, the steam generating component 120 is also in a dry-burning state, with a high overall temperature, which affects its service life. If a coating is used, it will affect the reliability of the coating; (3) During this period, the steam generating component 120 will rise to a high temperature. In the early stage of water intake, obvious modal boiling will occur. The steam generating component 120 and water heat transfer is slow. On the one hand, the violent boiling of water at this time will generate noise, and hot water may splash out and injure people. On the other hand, since the temperature of the steam generating component 120 cannot be reduced quickly, the steam generating component 120 cannot be restored to work quickly due to the influence of thermistors or temperature controllers and other protective devices, which further prolongs the steam interruption time.

[0116] The top surface of the heating plate 121 is the heating surface 124, which is used to heat the water in the steam generator 122. The heating surface 124 is divided into two parts, namely the first part 125 and the second part 126. During the entire cooking process, the heating plate 121 has a first state and a second state. In the first state, the difference between the highest temperature of the first part 125 and the highest temperature of the second part 126 is less than or equal to a preset value. The highest temperature of the first part 125 may be higher than the highest temperature of the second part 126, and the highest temperature of the second part 126 may also be higher than the highest temperature of the first part 125. However, the difference between the highest temperature of the first part 125 and the highest temperature of the second part 126 will not exceed the preset value. That is, the highest temperature of the first part 125 and the highest temperature of the second part 126 can be basically the same or fluctuate within a certain range. Therefore, in the first state, both the first part 125 and the second part 126 are covered with water, and the water on the first part 125 and the second part 126 has not boiled dry.

[0117] In the second state, the heating plate 121 has a higher maximum temperature in the first part 125 than in the second part 126, and the difference between the maximum temperatures of the first part 125 and the second part 126 is greater than the preset value T3. This indicates that at least a portion of the first part 125 is in a dry-burning state, meaning the water in the first part 125 dries up before the water in the second part 126. Since the temperature switch 131 is opposite to the first part 125, its temperature also increases, reaching the first set temperature. During this process, water covers the second part 126, and water continues to be heated on the second part 126. Through this solution, when water begins to enter the steam generator 122, the second part 126 heats the water and generates steam, helping to achieve uninterrupted steam throughout the entire operation. This significantly shortens the dry-burning time of the entire steam generator assembly 120, avoids or reduces steam interval problems, and lowers the maximum temperature and dry-burning area reached during the dry-burning stage of the steam generator assembly 120, thus improving the reliability of the steam generator assembly 120.

[0118] In one possible application, with the bottom surface 111 of the base 110 as a reference, the first part 125 is higher than the second part 126.

[0119] As the water in the steam generator 122 gradually evaporates, the liquid level in the steam generator 122 gradually decreases. The water at the higher position on the heating surface 124 evaporates first. Taking the first part 125 and the second part 126 as examples, when the amount of water in the steam generator 122 is small, the height of the first part 125 is higher, so the water on the first part 125 evaporates first. At this time, the first part 125 is in a dry-burning state, and the temperature of the first part 125 begins to rise. Since the temperature switch 131 is opposite to the first part 125, the temperature of the temperature switch 131 will also rise, so that the temperature of the temperature switch 131 can reach the first set temperature. During this process, water on the second part 126 is still being heated continuously. With this solution, when water begins to enter the steam generator 122, the second part 126 heats the water and generates steam, which helps to achieve uninterrupted steam throughout the entire working process, greatly shortens the dry burning time of the entire steam generator assembly 120, avoids the problem of steam interval or shortens the steam interval time, and reduces the maximum temperature reached and the area of ​​dry burning of the steam generator assembly 120 during the dry burning stage, thereby improving the reliability of the steam generator assembly 120.

[0120] When the first part 125 is higher than the second part 126, the specific implementation method can refer to the implementation method in any of the above embodiments.

[0121] In other embodiments, the heating temperature on the heating plate 121 can be changed so that the temperature at the first part 125 is higher and the temperature at the second part 126 is lower. When there is less water on the heating surface 124, the water on the first part 125 will boil dry first.

[0122] In some embodiments, the preset value T3 may optionally satisfy: 5℃≤T3≤15℃.

[0123] In the first state, the difference between the highest temperature of the first part 125 and the highest temperature of the second part 126 satisfies: 5℃≤T3≤15℃. Under this condition, the difference between the highest temperature of the first part 125 and the highest temperature of the second part 126 is small, indicating that the water on both the first part 125 and the second part 126 has not been boiled dry.

[0124] For example, T3 is 5°C, 10°C, or 15°C.

[0125] In an embodiment of this utility model, a cooking device is provided, comprising: a base assembly as described in any of the above embodiments.

[0126] For example, the cooking equipment can be a steam stew pot, a steam cooking machine, etc.

[0127] The water supply end 200 is a water tank, which is mounted on the base assembly 100, giving the cooking device water storage capacity.
