Description

Technical Field

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

[0002] Currently, for electric hot pots with detachable power cords, the temperature sensor on the power cord may deform during transportation due to collisions, thus affecting the accuracy of temperature sensing. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, firstly, this utility model proposes a power coupler for use in cooking equipment, the cooking equipment including a container, the power coupler including: a connecting wire; a plug connected to one end of the connecting wire; a housing connected to the other end of the connecting wire; a temperature sensing part located inside the housing, the temperature sensing part having a plug hole for connecting to a heat-conducting component on the container; and a temperature control component connected to the temperature sensing part, the temperature control component switching on and off according to the temperature of the temperature sensing part.

[0005] The two ends of the connecting cable are connected to the plug and the housing, respectively. The plug is used to connect to the power source, and the housing is used to connect to the socket on the cooking device. The power source supplies power to the cooking device through the power coupler.

[0006] A temperature sensing element is installed inside the casing. When the casing is connected to the port on the cooking device, the temperature of the container can be conducted to the temperature sensing element. A temperature control component is installed on the temperature sensing element, which can act according to the temperature of the sensing element. When the temperature of the container is too high, the temperature of the container is abnormal, and the temperature of the temperature sensing element is also too high. At this time, the temperature control component disconnects the power supply and the heating element in the cooking device, and the heating element stops heating the container, thereby reducing the temperature of the container to a reasonable range.

[0007] The temperature of the container is conducted to the temperature control component through the temperature sensing element. In this solution, the temperature sensing element is set inside the shell, that is, the temperature sensing element does not extend to the outside of the shell. By embedding the temperature sensing element inside the shell, the temperature sensing element is less likely to come into contact with external components. In scenarios such as transportation or handling, the temperature sensing element is less likely to be touched, thereby avoiding deformation of the temperature sensing element and ensuring that the temperature sensing element can stably and accurately conduct the temperature to the temperature control component.

[0008] The temperature sensing element, built into the housing, has a connector hole. When connecting the temperature sensing element to the connector, the heat-conducting component on the cooking device needs to be inserted into the connector hole to make contact with the temperature sensing element. Compared to the external temperature probe of the coupler in related technologies, the temperature sensing element in this solution does not protrude from the housing. Therefore, the distance between the position of the heat-conducting component in the power coupler and the temperature control component is smaller. When the temperature of the container is conducted to the temperature sensing element, the temperature sensing element can quickly conduct the temperature to the temperature control component, reducing energy loss during temperature conduction, avoiding temperature deviation in the temperature control process, and ensuring the accuracy of temperature control.

[0009] In some technical solutions, optionally, the housing is provided with mounting holes, and the temperature sensing part and the mounting holes are spaced apart.

[0010] The housing has mounting holes through which the heat-conducting component extends into the housing. There is a gap between the temperature sensing part and the outer surface of the housing, which further increases the difficulty of contact between the external component and the temperature sensing part, thereby helping to further reduce the damage rate of the temperature sensing part.

[0011] In some technical solutions, the temperature sensing part may optionally include: a first temperature sensing part having a plug hole; a second temperature sensing part connected to the first temperature sensing part, with an included angle between the first and second temperature sensing parts, and a temperature control component disposed on the second temperature sensing part.

[0012] A plug hole is provided on the first temperature sensing part. When the power coupler is connected to the plug on the cooking device, the heat-conducting component is plugged into the plug hole. The heat-conducting component and the temperature sensing part are connected by plugging. The two can be stably connected, which helps to improve the stability of the temperature conduction process.

[0013] The temperature control component is installed on the second temperature sensing part, which is connected to the first temperature sensing part. Since the temperature sensing part needs to be equipped with both a plug hole and the temperature control component, this solution sets an angle between the second and first temperature sensing parts, so that the first and second temperature sensing parts extend in different directions. This avoids the temperature sensing parts occupying too much space in one direction and avoids the housing being too large in one direction, which helps to improve the user's convenience in storing and using the power coupler.

[0014] In some technical solutions, the temperature sensing part may optionally include an extension part connected to the first temperature sensing part, the extension part having an extension hole that communicates with the insertion hole.

[0015] An extension section with an annular structure is provided on the first temperature sensing part. An extension hole is provided within the extension section, and this extension hole communicates with the insertion hole, effectively extending the length of the insertion hole. A heat-conducting component can be inserted into both the extension hole and the insertion hole, resulting in a larger contact area between the heat-conducting component and the temperature sensing part. This improves the thermal conductivity of both the container and the temperature sensing part, allowing the temperature control component to respond quickly to the container's temperature and enhancing the accuracy of the temperature control process.

[0016] In some technical solutions, optionally, the diameter of the extension hole is R1, where R1 satisfies: 0cm < R1 ≤ 20cm.

[0017] A larger orifice diameter results in a larger contact area between the extension and the heat-conducting component, leading to higher heat exchange efficiency. However, excessively large orifice diameters result in excessively large extension dimensions, consequently leading to an oversized housing, which is inconvenient for users to store and use. This design limits the orifice diameter to less than or equal to 20cm. By restricting the orifice diameter within this range, the housing size is prevented from becoming too large, thus improving the user's convenience in storing and using the power coupler.

[0018] In some technical solutions, the extension may be integrally formed with the first temperature sensing part; or the extension may be welded and fixed to the first temperature sensing part.

[0019] The extension and the first temperature sensing part can be an integral structure, and the heat on the extension can be quickly transferred to the first temperature sensing part, which is beneficial to improving the heat conduction efficiency.

[0020] Of course, to facilitate the processing of the temperature sensing part, the first temperature sensing part and the extension part can be processed separately, and then the extension part can be welded and fixed to the first temperature sensing part. Connecting the first temperature sensing part and the extension part by welding can also make the first temperature sensing part and the extension part fit tightly together, ensuring heat conduction efficiency.

[0021] In some technical solutions, optionally, a guide portion is provided inside the housing to guide the heat-conducting component to the insertion hole.

[0022] Inside the housing is a guide section that guides the heat-conducting component, ensuring that it is accurately inserted into the insertion hole without requiring frequent adjustments to the relative position of the heat-conducting component and the insertion hole, thus guaranteeing convenience during the installation of the power coupler.

[0023] In some technical solutions, optionally, the length of the temperature sensing part is L, where 0m < L ≤ 1m.

[0024] The length of the temperature sensing element can be increased or decreased proportionally to the length of the housing. For larger housings, the size of the temperature sensing element can be increased accordingly. If the temperature sensing element is too long, it may affect the response speed of the temperature control component. In this solution, the length of the temperature sensing element is limited to less than or equal to 1m. Within this range, the temperature of the container can be quickly conducted to the temperature control component, ensuring that the temperature control component has a good response speed.

[0025] In some technical solutions, the temperature control component may optionally include: a temperature controller connected to the temperature sensing element; and a circuit breaker connected to the temperature sensing element.

[0026] The temperature of the container is transmitted to the thermostat via the temperature sensor. The thermostat controls the tripping of the cooking equipment during normal operation, thus keeping the container temperature within the range corresponding to the current setting. The container temperature can also be transmitted to the circuit breaker via the temperature sensor. If the container temperature becomes too high, the circuit breaker disconnects the power supply to the heating element, ensuring safety during cooking.

[0027] In some technical solutions, the circuit breaker is optionally located on the adjacent side of the thermostat.

[0028] The circuit breaker is placed on the side of the thermostat, and the circuit breaker and thermostat are installed adjacent to each other on the temperature sensing part. This ensures that the circuit breaker and thermostat collect approximately the same temperature from the temperature sensing part, allowing the circuit breaker to respond quickly based on the temperature of the temperature sensing part. This avoids the problem of excessive protection distance caused by the circuit breaker being placed too far away.

[0029] To ensure a rapid response from the thermostat, there is usually not a large gap between the thermostat and the container. The circuit breaker is located on the adjacent side of the thermostat, so there is also not a large gap between the circuit breaker and the container. The rapid response of the circuit breaker can reduce safety hazards and ensure the safety of users during the use of cooking equipment.

[0030] In some technical solutions, optionally, the width of the thermostat is W, and the distance between the thermostat and the circuit breaker is less than W.

[0031] The distance between the thermostat and the circuit breaker is less than the width of the thermostat. Within the above range, the distance between the thermostat and the circuit breaker is relatively small, so that the temperature conducted from the temperature sensing part to the thermostat and the temperature conducted to the circuit breaker are basically the same, which is beneficial for the circuit breaker to respond quickly.

[0032] In some technical solutions, optionally, the number of circuit breakers is at least one.

[0033] When there is only one circuit breaker, the power supply to the cooking appliance stops when the circuit breaker disconnects the circuit. When there are two or more circuit breakers, each circuit breaker is connected to one circuit loop. Multiple circuit loops can be set up inside the cooking appliance. For example, the heating element is in a separate circuit loop, the light source on the cooking appliance body is in a separate circuit loop, and the display component of the cooking appliance is in a separate circuit loop. Each circuit loop is equipped with a circuit breaker, so that the light source can continue to work when the circuit containing the heating element is broken.

[0034] In some technical solutions, optionally, the housing is provided with at least one electrical connection part for connecting with the heating element in the cooking device. The electrical connection part includes a first connection hole and a second connection hole. The first connection hole is used to connect with one end of the heating element, and the second connection hole is used to connect with the other end of the heating element.

[0035] An electrical connection portion is provided on the housing. When the power coupler is plugged into the main body, the electrical connection portion is electrically connected to the heating element on the main body. The heating element typically has two connection ends, namely a neutral wire end and a live wire end. An electrical connection portion includes a first connection hole and a second connection hole. The live wire end can be inserted into the first connection hole, and the neutral wire end can be inserted into the second connection hole.

[0036] The number of electrical connections can be multiple, allowing for cooperation with multiple heating elements to achieve cooking functions with different power levels.

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

[0038] In some technical solutions, the cooking device may optionally include: a body; a container disposed on the body; and a heat-conducting component disposed within the body, wherein the heat-conducting component is connected to the container, the heat-conducting component is inserted into the insertion hole, and the temperature of the container is conducted to the temperature sensing part through the heat-conducting component.

[0039] The heat-conducting component is used to connect with the insertion hole. The temperature of the container is conducted to the temperature control component sequentially through the heat-conducting component and the temperature sensing element. Since the heat-conducting component is connected to the container, its temperature is basically the same as that of the container. When the heat-conducting component and the temperature sensing element are connected, the distance between the heat-conducting component and the temperature control component is small, which allows the temperature of the container to be quickly conducted to the temperature control component, shortening the heat conduction distance and facilitating a rapid response from the temperature control component.

[0040] In some technical solutions, the heat-conducting component can optionally be integrally molded with the container.

[0041] The heat-conducting component and the container are designed as a single unit, so that the temperature of the container and the temperature of the heat-conducting component are basically the same, and there will be no large temperature difference between them. The temperature of the heat-conducting component is basically the temperature of the container. The distance between the heat-conducting component and the temperature control component is the effective heat conduction distance. By shortening the heat conduction distance in the above way, the response speed of the temperature control component is improved.

[0042] In some technical solutions, the cooking device may optionally include: heating elements for heating the container, wherein the number of heating elements is greater than 0 and less than or equal to 100.

[0043] An electrical connection portion is provided on the housing. When the power coupler is plugged into the main body, the electrical connection portion is electrically connected to the heating element on the main body. The heating element typically has two connection ends, namely a neutral wire end and a live wire end. An electrical connection portion includes a first connection hole and a second connection hole. The live wire end can be inserted into the first connection hole, and the neutral wire end can be inserted into the second connection hole.

[0044] The number of heating elements can be multiple, allowing them to cooperate with multiple electrical connections to achieve cooking functions with different power levels.

[0045] In some technical solutions, the cross-section of the heat-conducting element may optionally be circular or polygonal.

[0046] The cross-section of the heat-conducting component can be circular or polygonal, and the shape of the heat-conducting component can be designed according to actual usage requirements.

[0047] In some technical solutions, optionally, the maximum width of the heat-conducting component is R2, where R2 satisfies: 0cm < R2 ≤ 20cm.

[0048] The wider the heat-conducting component, the larger the contact area between it and the temperature-sensing part, resulting in higher heat exchange efficiency. However, if the width of the heat-conducting component is too large, it will occupy too much space within the main body. In this solution, the maximum width of the heat-conducting component is limited to less than or equal to 20cm. Limiting the width of the heat-conducting component within this range avoids making the component too large and facilitates a more rational layout of the internal space.

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 8This invention describes a power coupler and a cooking device provided according to some embodiments of the present invention.

[0064] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of this utility model, a power coupler 100 is provided. The power coupler 100 is used in a cooking device 600, which includes a container 300. The power coupler 100 includes a connecting wire 110, a plug 120, a housing 130, a temperature sensing part 140, and a temperature control component 150. The plug 120 is connected to one end of the connecting wire 110, and the housing 130 is connected to the other end of the connecting wire 110. The temperature sensing part 140 is located inside the housing 130 and has a plug hole 141 for connecting to a heat-conducting element 400 on the container 300. The temperature sensing part 140 is used to conduct the temperature of the container 300. The temperature control component 150 is connected to the temperature sensing part 140 and switches on and off according to the temperature of the temperature sensing part 140.

[0065] The two ends of the connecting wire 110 are connected to the plug 120 and the housing 130 respectively. The plug 120 is used to connect to the power supply, and the housing 130 is used to connect to the socket 210 on the cooking device 600. The power supply provides power to the cooking device 600 through the power coupler 100.

[0066] A temperature sensing element 140 is disposed inside the housing 130. When the housing 130 is connected to the inlet 210 on the cooking appliance 600, the temperature of the container 300 can be conducted to the temperature sensing element 140. A temperature control component 150 is installed on the temperature sensing element 140, and the temperature control component 150 can act according to the temperature of the temperature sensing element 140. When the temperature of the container 300 is too high, the temperature of the container 300 is abnormal, and the temperature of the temperature sensing element 140 is also too high. At this time, the temperature control component 150 disconnects the power supply and the heating element 500 in the cooking appliance 600, and the heating element 500 stops heating the container 300, thereby reducing the temperature of the container 300 to a reasonable range.

[0067] The temperature of container 300 is conducted to temperature control component 150 through temperature sensing element 140. In this solution, temperature sensing element 140 is set inside housing 130, that is, temperature sensing element 140 does not extend to the outside of housing 130. By embedding temperature sensing element 140 inside housing 130, temperature sensing element 140 is less likely to come into contact with external components of housing 130. In scenarios such as transportation or handling, temperature sensing element 140 is less likely to be touched, thereby avoiding deformation of temperature sensing element 140 and ensuring that temperature sensing element 140 can stably and accurately conduct temperature to temperature control component 150.

[0068] The temperature sensing element 140, built into the housing 130, is provided with a connector hole. When connecting the temperature sensing element 140 to the connector 210, the heat-conducting component 400 on the cooking device 600 needs to be inserted into the connector hole 141 to bring the heat-conducting component 400 into contact with the temperature sensing element 140. Compared to the externally mounted temperature probe of the coupler in related technologies, the temperature sensing element 140 in this solution does not protrude from the housing 130. Therefore, the distance between the position of the power coupler 100 used to connect the heat-conducting component 400 and the temperature control component 150 is smaller. When the temperature of the container 300 is conducted to the temperature sensing element 140, the temperature sensing element 140 can quickly conduct the temperature to the temperature control component 150, reducing energy loss during temperature conduction, avoiding temperature deviation in the temperature control process of the temperature control component 150, and ensuring the accuracy of temperature control.

[0069] In some embodiments, the housing 130 is optionally provided with a mounting hole 131, and the temperature sensing part 140 and the mounting hole 131 are spaced apart.

[0070] The housing 130 is provided with a mounting hole 131, through which the heat-conducting component 400 extends into the housing 130. There is a gap between the temperature sensing part 140 and the outer surface of the housing 130, which further increases the difficulty of contact between external components and the temperature sensing part 140, thereby helping to further reduce the damage rate of the temperature sensing part 140.

[0071] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the temperature sensing part 140 includes: a first temperature sensing part 142 and a second temperature sensing part 143. The first temperature sensing part 142 is provided with a plug hole 141, the second temperature sensing part 143 is connected to the first temperature sensing part 142, there is an included angle α between the first temperature sensing part 142 and the second temperature sensing part 143, and the temperature control component 150 is disposed on the second temperature sensing part 143.

[0072] A plug hole 141 is provided on the first temperature sensing part 142. When the power coupler 100 is connected to the plug 210 on the cooking device 600, the heat-conducting component 400 is plugged into the plug hole 141. The heat-conducting component 400 and the temperature sensing part 140 are connected by plugging. The two can be stably connected, which helps to improve the stability of the temperature conduction process.

[0073] The temperature control component 150 is installed on the second temperature sensing part 143, which is connected to the first temperature sensing part 142. Since the temperature sensing part 140 needs to be provided with both the insertion hole 141 and the temperature control component 150, this solution sets an angle between the second temperature sensing part 143 and the first temperature sensing part 142, so that the first temperature sensing part 142 and the second temperature sensing part 143 extend in different directions. This avoids the temperature sensing part 140 occupying too much space in one direction and avoids the housing 130 being too large in one direction, which is beneficial to improving the user's storage convenience and ease of use of the power coupler 100.

[0074] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the temperature sensing part 140 may optionally include an extension part 144, which is connected to the first temperature sensing part 142. The extension part 144 is provided with an extension hole 145, which is connected to the insertion hole 141.

[0075] An extension 144 is provided on the first temperature sensing part 142. The extension 144 has a ring structure, and an extension hole 145 is provided inside the extension 144. The extension hole 145 is connected to the insertion hole 141, which is equivalent to extending the length of the insertion hole 141. The heat-conducting component 400 can be inserted into the extension hole 145 and the insertion hole 141, so that the heat-conducting component 400 and the temperature sensing part 140 have a large contact area. This is beneficial to improving the heat conduction efficiency of the container 300 and the temperature sensing part 140, so that the temperature control component 150 can respond quickly according to the temperature of the container 300, which is beneficial to improving the accuracy of the temperature control process.

[0076] like Figure 5 As shown, in some embodiments, optionally, the diameter of the extension hole 145 is R1, where R1 satisfies: 0cm < R1 ≤ 20cm.

[0077] The larger the diameter of the extension hole 145, the larger the contact area between the extension portion 144 and the heat-conducting element 400, resulting in higher heat exchange efficiency. However, if the diameter of the extension hole 145 is too large, the size of the extension portion 144 will also be too large, leading to an excessively large housing 130, which is inconvenient for users to store and use. In this solution, the diameter of the extension hole 145 is limited to less than or equal to 20 cm. By limiting the diameter of the extension hole 145 to this range, the size of the housing 130 is prevented from becoming too large, which improves the user's convenience in storing and using the power coupler 100.

[0078] In some embodiments, the extension 144 may be integrally formed on the first temperature sensing part 142, or the extension 144 may be welded to the first temperature sensing part 142.

[0079] The extension 144 and the first temperature sensing part 142 can be an integral structure, and the heat on the extension 144 can be quickly transferred to the first temperature sensing part 142, which is beneficial to improving the heat conduction efficiency.

[0080] Of course, to facilitate the processing of the temperature sensing part 140, the first temperature sensing part 142 and the extension part 144 can be processed separately, and then the extension part 144 can be welded and fixed to the first temperature sensing part 142. By connecting the first temperature sensing part 142 and the extension part 144 by welding, the first temperature sensing part 142 and the extension part 144 can be tightly fitted together, ensuring heat conduction efficiency.

[0081] Combination Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, a guide portion 132 is provided inside the housing 130, which is used to guide the heat-conducting element 400 to the insertion hole 141.

[0082] Inside the housing 130, there is a guide portion 132, which guides the heat-conducting component 400 so that the heat-conducting component 400 is accurately inserted into the insertion hole 141 under the guidance of the guide portion 132. This eliminates the need for the user to frequently adjust the relative position of the heat-conducting component 400 and the insertion hole 141, ensuring the convenience of the power coupler 100 during installation.

[0083] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, the length of the temperature sensing part 140 is L, where 0m < L ≤ 1m.

[0084] The length of the temperature sensing element 140 can be increased or decreased proportionally to the length of the housing 130. For a larger housing 130, the size of the temperature sensing element 140 can be increased accordingly. If the length of the temperature sensing element 140 is too long, it may affect the response speed of the temperature control component 150. In this solution, the length of the temperature sensing element 140 is limited to less than or equal to 1m. Within this range, the temperature of the container 300 can be quickly conducted to the temperature control component 150, ensuring that the temperature control component 150 has a good response speed.

[0085] Combination Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the temperature control component 150 may optionally include a temperature controller 151 and a circuit breaker 152, wherein the temperature controller 151 is connected to the temperature sensing unit 140 and the circuit breaker 152 is connected to the temperature sensing unit 140.

[0086] The temperature of container 300 can be transmitted to thermostat 151 via temperature sensor 140. Thermostat 151 is used to control the tripping of cooking equipment 600 during normal operation, thereby controlling the temperature of container 300 within the range corresponding to the current setting. The temperature of container 300 can also be transmitted to circuit breaker 152 via temperature sensor 140. When the temperature of container 300 is too high, circuit breaker 152 disconnects the power supply to heating element 500, thereby ensuring safety during the cooking process.

[0087] Combination Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the circuit breaker 152 is optionally located adjacent to the thermostat 151.

[0088] The circuit breaker 152 is placed on the side of the temperature controller 151, and the circuit breaker 152 and the temperature controller 151 are arranged adjacent to each other. The installation positions of the circuit breaker 152 and the temperature controller 151 on the temperature sensing part 140 are close to each other, so that the temperature collected by the circuit breaker 152 and the temperature controller 151 on the temperature sensing part 140 is basically the same. This allows the circuit breaker 152 to respond quickly according to the temperature of the temperature sensing part 140, avoiding the problem of excessive protection distance caused by the circuit breaker 152 being set too far away.

[0089] To ensure that the thermostat 151 can respond quickly, there is usually not a large gap between the thermostat 151 and the container 300. The circuit breaker 152 is located on the adjacent side of the thermostat 151, so there is also not a large gap between the circuit breaker 152 and the container 300. The quick response of the circuit breaker 152 can reduce safety hazards and ensure the safety of users during the use of the cooking equipment 600.

[0090] Combination Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, in some embodiments, optionally, the width of the thermostat 151 is W, and the distance H between the thermostat 151 and the circuit breaker 152 is less than W.

[0091] The distance between the thermostat 151 and the circuit breaker 152 is less than the width of the thermostat 151. Within the above range, the distance between the thermostat 151 and the circuit breaker 152 is small, so that the temperature conducted from the temperature sensing part 140 to the thermostat 151 and the temperature conducted to the circuit breaker 152 are basically the same, which is beneficial for the circuit breaker to respond quickly.

[0092] In some embodiments, the number of circuit breakers 152 may be at least one.

[0093] When there is only one circuit breaker 152, the power supply to the cooking appliance 600 stops when the circuit breaker 152 disconnects the circuit. When there are two or more circuit breakers 152, each circuit breaker 152 is connected to one circuit loop. Multiple circuit loops can be set in the body 200 of the cooking appliance 600. For example, the heating element 500 is in a separate circuit loop, the light source on the body 200 is in a separate circuit loop, and the display component of the cooking appliance 600 is in a separate circuit loop. Each circuit loop is equipped with a circuit breaker 152. When the circuit containing the heating element 500 is disconnected, the light source can still continue to work.

[0094] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the housing 130 is provided with at least one electrical connection portion 133, which is used to connect with the heating element 500 in the cooking device 600. The electrical connection portion 133 includes a first connection hole 134 and a second connection hole 135. The first connection hole 134 is used to connect with one end of the heating element 500, and the second connection hole 135 is used to connect with the other end of the heating element 500.

[0095] An electrical connection portion 133 is provided on the housing 130. When the power coupler 100 is plugged into the body 200, the electrical connection portion 133 is electrically connected to the heating element 500 on the body 200. The heating element 500 typically has two connection ends, namely a neutral wire end 510 and a live wire end 520. An electrical connection portion 133 includes a first connection hole 134 and a second connection hole 135. The live wire end 520 can be plugged into the first connection hole 134, and the neutral wire end 510 can be plugged into the second connection hole 135.

[0096] The number of electrical connection parts 133 can be multiple, so that they can be used with multiple heating elements 500 to realize cooking functions with different power levels.

[0097] In some embodiments of this utility model, a cooking device 600 is proposed, including a power coupler 100 as described in any of the above embodiments, and can achieve the same technical effect, which will not be repeated here.

[0098] Combination Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, in some embodiments, optionally, the cooking device 600 further includes: a body 200, a container 300, and a heat-conducting element 400. The container 300 and the heat-conducting element 400 are disposed on the body 200. The heat-conducting element 400 is connected to the container 300 and inserted into the insertion hole 141. The temperature of the container 300 is conducted to the temperature sensing part 140 through the heat-conducting element 400.

[0099] The heat-conducting component 400 is used to connect with the insertion hole 141. The temperature of the container 300 is conducted to the temperature control component 150 through the heat-conducting component 400 and the temperature sensing part 140 in sequence. Since the heat-conducting component 400 is connected to the container 300, the temperature of the heat-conducting component 400 is basically the same as the temperature of the container 300. When the heat-conducting component 400 is connected with the insertion hole 141 on the temperature sensing part 140, the distance between the heat-conducting component 400 and the temperature control component 150 is small, so that the temperature of the container 300 can be quickly conducted to the temperature control component 150, shortening the heat conduction distance and facilitating the rapid response of the temperature control component 150.

[0100] In some embodiments, the heat-conducting element 400 may be integrally formed with the container 300.

[0101] The heat-conducting component 400 and the container 300 are designed as a single unit, so that the temperature of the container 300 and the temperature of the heat-conducting component 400 are basically the same, and there will be no large temperature difference between them. The temperature of the heat-conducting component 400 is basically the temperature of the container 300. The distance between the heat-conducting component 400 and the temperature control component 150 is the effective heat conduction distance. By means of the above method, the heat conduction distance is shortened and the response speed of the temperature control component 150 is improved.

[0102] In other embodiments, the heat-conducting element 400 can also be connected to the container 300 by compression fitting. Of course, the connection method between the heat-conducting element 400 and the container 300 is not limited to the above-described method. The heat-conducting element 400 can be made of a material with a high thermal conductivity, thereby improving the thermal conductivity.

[0103] The thermostat 151 is used to control the switching of the cooking equipment 600 during normal operation. In abnormal situations, such as when the thermostat 151 fails, the circuit breaker 152 can protect the temperature sensor as quickly as possible because its temperature point is close to that of the thermostat 151.

[0104] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, the cooking device 600 further includes a heating element 500, which is used to heat the container 300, and the number of heating elements 500 is greater than 0 and less than or equal to 100.

[0105] An electrical connection portion 133 is provided on the housing 130. When the power coupler 100 is plugged into the body 200, the electrical connection portion 133 is electrically connected to the heating element 500 on the body 200. The heating element 500 typically has two connection ends, namely a neutral wire end 510 and a live wire end 520. An electrical connection portion 133 includes a first connection hole 134 and a second connection hole 135. The live wire end 520 can be plugged into the first connection hole 134, and the neutral wire end 510 can be plugged into the second connection hole 135.

[0106] The number of heating elements 500 can be multiple, so that they can be used with multiple electrical connection parts 133 to realize cooking functions with different power levels.

[0107] In some embodiments, the cross-section of the heat-conducting element 400 may be circular or polygonal.

[0108] The cross-section of the heat-conducting component 400 can be circular or polygonal, and the shape of the heat-conducting component 400 can be designed according to actual usage requirements.

[0109] like Figure 7 As shown, in some embodiments, optionally, the maximum width of the heat-conducting element 400 is R2, where R2 satisfies: 0cm < R2 ≤ 20cm.

[0110] The wider the heat-conducting component 400, the larger the contact area between it and the temperature-sensing part 140, resulting in higher heat exchange efficiency. However, if the width of the heat-conducting component 400 is too large, it will occupy too much space within the main body 200. In this solution, the maximum width of the heat-conducting component 400 is limited to less than or equal to 20cm. Limiting the width of the heat-conducting component 400 within this range avoids making the size of the heat-conducting component 400 too large, which is beneficial for a reasonable layout of the space within the main body 200.

[0111] For example, the cooking device 600 in this embodiment can be a hot pot, a steamer, or a wok.

[0112] In an embodiment of this utility model, the power coupler 100 is assembled with the body 200 by inserting the heat-conducting component 400 on the body 200 into the insertion hole 141 on the temperature sensing part 140.

[0113] The extension 144 and the first temperature sensing part 142 are integrally formed or formed in other ways, such as by welding.

[0114] The circuit breaker 152 can be of different specifications and can be installed in different ways to form a complete protection circuit together with the thermostat 151, the heat-conducting component 400, etc.

[0115] Figure 6The neutral wire 510 and the live wire 520 are inserted into the same power coupler 100 (or another heating element 500 is electrically connected to the power coupler 100). Figure 6 There are two heating elements 500, and the heating elements 500 are connected to the neutral and live wires of the power coupler 100 to form a circuit.

[0116] The shape of the heat-conducting component 400 is not limited (circular, square, etc.), the position of the heat-conducting component 400 inside the body 200 is not limited (front, back, left, right, etc.), the method of fitting the heat-conducting component 400 to the body 200 is not limited (pressing, welding, integral molding, screw fixing, etc.), and the material used for the heat-conducting component 400 is not limited (materials with high thermal coefficients such as aluminum). The width R2 of the heat-conducting component 400 is: 0cm < R2 ≤ 20cm, and the number of heat-conducting components 400 assembled in the product is greater than 0 and less than 100.

[0117] The shape of the extension 144 is consistent with that of the heat-conducting element 400. The radial dimension of the extension 144 is less than or equal to 20cm, and the length of the temperature-sensing part 140 is less than or equal to 1m.

[0118] The circuit breaker 152 can be a fuse, a trip thermostat, etc. The number of circuit breakers 152 is less than or equal to 5, and their position within the power coupler 100 is not limited.

[0119] The number of heating elements 500 that can be paired with the same power coupler 100 is unlimited.

[0120] The number of neutral / live wire interfaces of the heating element 500 and the power coupler 100 is less than or equal to 100.

[0121] After setting the above parameters, the user experience is greatly reduced. Previously, due to the excessively long sensing distance and complex structure, the temperature controller 151 would trip or fail to activate after reaching the internal temperature of the body 200, resulting in a poor user experience. The current structure can achieve real-time temperature sensing, reducing temperature loss and transmission time.

[0122] The above settings can significantly solve the safety hazards such as fire caused by the slow temperature sensing and untimely action of the circuit breaker 152 when the temperature controller 151 fails in this type of power coupler 100 in the current industry.

[0123] The new structure eliminates the risk of deformation of the temperature sensing probe due to collisions during transportation, which could affect its temperature sensing capabilities.

[0124] The structure of the multi-heating element 500 allows for multiple cooking scenarios with different power levels.

[0125] In this utility model, the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0126] In the description of this specification, the terms "one embodiment," "some embodiments," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
