Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to an electric control panel assembly, an electric heating appliance and an electric heating device. Background Art

[0002] Existing electric heating appliances, such as electronic kettles, require an electronic control board to control the kettle and other products. Furthermore, a connector is required on the kettle body assembly, which then connects to the power supply on the base assembly to power the components on the kettle body assembly. However, in this structure, the connector and electronic control board are separate components, both located at the bottom of the kettle body. This results in a large number of components at the bottom of the kettle body, making installation inconvenient. Furthermore, during installation, this structure requires the connector and electronic control board to be separately installed at the bottom of the kettle body, requiring at least multiple installation steps, resulting in low installation efficiency and high overall product cost.

[0003] Therefore, how to propose an electric heating device that can simplify the product structure and reduce product cost has become a problem that needs to be solved urgently. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, one object of the present invention is to provide an electric control board assembly.

[0006] Another object of the present invention is to provide an electric heating appliance comprising the above-mentioned electric control board assembly.

[0007] Another object of the present invention is to provide an electric heating device comprising the above-mentioned electric heating appliance.

[0008] In view of this, an embodiment of the first aspect of the present invention provides an electric control board assembly for an electric heating appliance, wherein the electric heating appliance includes an appliance assembly, wherein the electric control board assembly includes: an electric control board; a connector including a plurality of power connectors for connecting electricity, the connector and the electric control board are assembled into one, and after the connector and the electric control board are assembled into one, they can be installed to the appliance assembly and control the operation of the appliance assembly.

[0009] The electric control board assembly provided according to an embodiment of the present invention can be specifically used for electric heating appliances such as kettles, and preferably, for electronic electric heating appliances such as electronic kettles. The electric control board assembly includes an electric control board and a connector that are assembled into one body. The electric control board can be used to specifically control the operation of the electric heating appliance, such as controlling whether the product is powered on or not, such as controlling whether the heating device is powered on or not, based on the temperature detected by the temperature sensor. Of course, the electric control board can also be used to control other operations of the product. The connector is mainly used to connect to other power supply devices or external power sources to realize power supply of the electric heating appliance. For example, the connector can be connected to the power supply device on the base assembly of the electric heating device so that the power supply device and the connector can be used to introduce electricity from the base assembly to the appliance assembly of the electric heating appliance. Specifically, the power connection on the connector can specifically include a positive terminal connected to the live wire and a negative terminal connected to the neutral wire. The electric control board assembly provided by this structure integrates the connector and the electric control board into a single unit, achieving modularization of multiple discrete components. This allows the electric control board assembly to integrate control and power connection functions. In actual use, the electric control board assembly can be assembled as a whole and then installed as a whole on the kettle body or other appliance component of the electric heating appliance. This optimizes the product structure and reduces the space occupied by the electric control board assembly at the bottom of the kettle body or other appliance component. This solves the problem of the existing technology in which the electric control board and the existing connector are separate parts and are both installed at the bottom of the kettle body or other appliance component, resulting in a complex structure and inconvenient installation. Furthermore, this structure only requires the electric control board assembly to be installed as a whole on the kettle body or other appliance component, eliminating the need to install the connector and the electric control board in multiple steps. This simplifies the product installation steps, improves installation efficiency, reduces labor, and thus reduces the production cost of the product, solving the problem of excessively high production costs of products such as electronic kettles.

[0010] When the connector and the electronic control board are assembled into one, they can be assembled into a detachable structure in a detachable manner, or they can be assembled into a non-detachable integral structure by welding or other methods. In this application, "assembling multiple parts into one" means assembling multiple parts into a whole, rather than connecting multiple parts in an integral manner. Furthermore, when connecting the electronic control board and the connector, the connector can be directly rigidly connected to the electronic control board, such as by using a rigid connector such as metal, or a connecting wire can be provided between the electronic control board and the connector to achieve a non-rigid connection between the electronic control board and the connector.

[0011] In any of the above technical solutions, preferably, the electric control board includes a substrate and an electric control device, and the electric control device is mounted on the substrate; wherein the connector is mounted on the substrate.

The substrate is used to implement control operations, mount other components, and integrate circuits. The electrical control device is preferably a relay, which can control the on and off of the product's power supply. The connector can be directly assembled on the substrate.

[0013] In any of the above technical solutions, preferably, the electric control board assembly further includes: a detection element, mounted on the substrate and connected to the electric control device; wherein the electric control board, the connector and the detection element are assembled into one body.

[0014] In these technical solutions, the detection element can be specifically used to detect parameters such as the temperature, pressure or liquid level of the appliance component such as the kettle body, so that the temperature, pressure or liquid level parameters such as the electric heating appliance can be known at any time during operation, so that the electronic control board can perform subsequent product operation control based on these parameters. The electronic control board assembly provided by this structure assembles the connector, the detection element and the electronic control board into a whole, realizing the modularization of multiple discrete parts, so that the electronic control board assembly can integrate functions such as control, power connection and temperature measurement into one. In this way, when in use, the electronic control board assembly can be assembled first, and then the electronic control board assembly can be installed as a whole on the appliance component such as the kettle body of the electric heating appliance. This can optimize the product structure and reduce the space occupied by the electronic control board assembly at the bottom of the appliance component such as the kettle body, solving the problem that the electronic control board, the thermostat and the existing connector are all independent parts and are all arranged at the bottom of the appliance component such as the kettle body, which makes the structure of the bottom of the appliance component such as the kettle body relatively complicated and inconvenient to install.

[0015] In any of the above technical solutions, preferably, the detection element includes a pressure sensor and / or a temperature sensor.

[0016] In these technical solutions, the detection element can preferably be a temperature sensor, which can detect the temperature so that the product can be controlled based on the temperature of the kettle body or other appliance components.

Of course, the detection element can also be other components that can detect container parameters, such as a liquid level sensor.

The positive and negative connectors can be installed on the baseplate using any conventional installation method, but preferably, they are installed on the baseplate by riveting or welding, as these methods are more reliable and easy to operate. Of course, the positive and negative connectors can also be installed on the baseplate using snaps, screws, plug-ins, or other installation methods. Soldering is preferred for welding, while terminal blocks are preferred for plugging.

[0020] In any of the above technical solutions, preferably, the electrical control device is a relay.

[0021] In these technical solutions, the electrical control device is a relay, and the relay can be used to control the on and off of the power supply, so that the start and stop control of the product can be achieved through the control of the electrical control board.

[0022] In any of the above technical solutions, preferably, the electronic control board is a PCB board.

[0023] In these technical solutions, the electronic control board is preferably a PCB board, because the PCB board is a common electronic control component, and thus it is relatively common and easier to purchase.

[0024] In any of the above technical solutions, preferably, the connector further comprises: a grounding structure connected to the appliance assembly for grounding the appliance assembly.

[0025] In these technical solutions, a grounding structure can be provided on the connector. One end of the grounding structure is used to connect to the ground wire of the user's home three-wire power cord, while the other end of the grounding structure can be directly or indirectly connected to the appliance components such as the kettle body. In this way, the appliance components can be grounded through the grounding structure.

Simultaneously, the first conductive connector can be connected to a grounding structure, so that the grounding structure can be connected to the appliance assembly via the first conductive connector, thereby achieving grounding of the appliance assembly. In another solution, a second conductive connector can be provided directly between the appliance assembly and the grounding structure to achieve a connection between the appliance assembly and the grounding structure. In this case, the second conductive connector can be provided on the electrical control panel or independently of the electrical control panel. Of course, the second conductive connector can also be a structure provided on a connector and connected to the appliance assembly. Furthermore, the grounding structure can also be directly mounted to the appliance assembly to achieve a grounding connection with the appliance assembly. For example, an extension structure can be provided on the grounding structure, and then the extension structure can be secured to the appliance assembly via the first fastener.

[0028] In the above-mentioned another technical solution, preferably, a third conductive connector connected to the grounding structure is provided on the electric control board, and the electric control board assembly also includes a sensor, and the sensor includes: a fourth conductive connector connected to the instrument assembly; and a fifth conductive connector, one end of the fifth conductive connector is connected to the fourth conductive connector, and the other end of the fifth conductive connector is connected to the third conductive connector.

In this case, a fifth conductive connector may be provided on the sensor to connect the sensor to the connector. Preferably, a third conductive connector may be provided on the electronic control board so that the fifth conductive connector on the sensor is first connected to the electronic control board and then to the ground structure via the electronic control board.

[0030] Further preferably, the fourth conductive connecting member may be a sensor mounting plate, and the sensor also includes a sensor element for detection, a sensor line for sending information sensed by the sensor element, a wiring terminal for connecting to an electrical control board, and a sealing structure, such as sealant, for sealing the sensor to the appliance assembly.

[0031] In any of the above technical solutions, preferably, the connector is provided with a three-layer structure from the inside to the outside, one layer of the three-layer structure is a negative electrode connector, another layer of the three-layer structure is a positive electrode connector, and the third layer of the three-layer structure is a grounding structure.

[0032] In these technical solutions, the connector can preferably be configured as a three-layer structure from the inside out, so as to serve as the connector's negative terminal, positive terminal, and grounding structure. Preferably, the grounding structure can be configured as the innermost layer, the negative terminal as the outermost layer, and the positive terminal as the middle layer. Of course, the positions of the negative terminal, positive terminal, and grounding structure can also be interchanged. For example, the positive terminal can be configured as the innermost layer, the negative terminal as the middle layer, and the grounding structure as the outermost layer.

[0033] In another solution, the negative electrode connector, the positive electrode connector and the grounding structure may also be three independently provided conductive sheets, and do not necessarily have to be a nested three-layer structure.

[0034] In any of the above technical solutions, preferably, the grounding structure is a grounding wire or a grounding conductive sheet, and / or the grounding structure is riveted or welded to the electric control board.

[0035] In these technical solutions, the grounding structure can be specifically a grounding wire, a conductive sheet connected to the ground, or a grounding terminal. The type of grounding structure can be selected according to actual needs. Preferably, the grounding structure is a grounding wire, that is, the grounding structure is preferably a groundable wire. This can make the grounding structure simpler and thus reduce product costs. Preferably, the grounding structure is installed on the electronic control board by riveting or welding. Of course, the grounding structure can also be installed on the electronic control board by plugging.

[0036] In any of the above technical solutions, preferably, an extension structure is provided on the grounding structure.

[0037] In these technical solutions, by setting an extension structure on the grounding structure, the grounding structure can be connected to the appliance components such as the kettle body through the extension structure, which makes it more convenient to connect the grounding structure with the appliance components, the electronic control board or the sensor.

[0038] Further preferably, the extension structure is an elastic conductive sheet or a wire, which makes it easier to install the grounding structure and the kettle body and other appliance components.

[0039] In any of the above technical solutions, preferably, the grounding structure is a copper ring or a copper rod, and the extension structure is arranged on the copper ring or the copper rod and extends along the outer side of the copper ring or the copper rod.

[0040] In these technical solutions, the innermost layer of the three-layer structure can be preferably set as a grounding structure. In this case, the extension structure can first extend from the bottom of the grounding structure and then extend to the side of the connector. Of course, the extension structure can also be extended from the bottom to the top so that the extension structure can be fixed to the bottom of the appliance component such as the kettle body.

[0041] Further preferably, the grounding structure is a copper structure.

[0042] In any of the above technical solutions, the extension structure is preferably mounted on the appliance assembly via a threaded connector. In this arrangement, the extension structure can be mounted on the appliance assembly via a threaded connector, such as a screw or bolt. Preferably, holes are pre-drilled in the extension structure to facilitate installation with the screws or bolts. Alternatively, holes can be drilled in the extension structure during installation to facilitate installation with the screws or bolts. Alternatively, the extension structure can be mounted to the appliance assembly via self-tapping screws, eliminating the need for drilling holes in the extension structure. Furthermore, the extension structure can also be configured as a wire.

[0043] In any of the above technical solutions, preferably, the electric control board assembly further includes: a fuse, which is arranged on the connector or on the electric control board.

[0044] In these technical solutions, the fuse automatically disconnects when the current exceeds its limit, thereby preventing excessive current from flowing through the electronic control board. The fuse can be installed on the connector or electronic control board using screws, rivets, welding, elastic connections, snap-fit connections, and other connection methods.

[0045] In any of the above technical solutions, preferably, the connector is assembled on one side of the electric control board, an avoidance hole is provided on the electric control board, and an impact-resistant structure is provided on the connector, and the impact-resistant structure can pass through the avoidance hole.

[0046] In these technical solutions, when assembling the connector and the electric control board, the connector can be installed on the side of the electric control board away from the appliance assembly. By providing an avoidance hole on the electric control board and providing an impact-resistant structure on the connector, after the connector and the electric control board are assembled into a whole, the impact-resistant structure on the connector can pass through the electric control board and form a support on the other side of the electric control board. In this way, after the electric control board assembly is installed as a whole on the appliance assembly such as the kettle body, the impact-resistant structure can support the appliance assembly such as the kettle body, thereby preventing the appliance assembly such as the kettle body from directly squeezing the electric control board. In this way, the force applied to the electric control board can be improved, and the possibility of the electric control board being squeezed and damaged during use can be reduced.

[0047] In any of the above technical solutions, preferably, the impact-resistant structure is a plastic structure, a metal structure, a rubber structure, or a silicone structure.

[0048] In these technical solutions, the impact-resistant structure can be a plastic structure, a rubber structure, a silicone structure, or a metal structure, as long as it can bear a certain pressure. However, the impact-resistant structure can preferably be a softer structure such as plastic, rubber, or silicone, so that it can form a certain buffer for the impact force and improve the impact resistance of the impact-resistant structure.

[0049] In any of the above technical solutions, preferably, a first positioning structure is provided on the connector, a second positioning structure is provided on the electric control board, and the connector is mounted on the electric control board through the cooperation of the first positioning structure and the second positioning structure.

[0050] In these technical solutions, a first positioning structure can be provided on the connector, while a second positioning structure can be provided on the electronic control board. This allows the first and second positioning structures to cooperate to achieve preliminary positioning of the connector on the electronic control board. After this preliminary positioning, the positive and negative terminals of the connector can be directly connected to the electronic control board. This preliminary positioning can pre-fix the positions of the electronic control board and connector, preventing the positive and negative terminals of the connector from moving when connected to the electronic control board.

[0051] When the connector is equipped with an impact-resistant structure, the first positioning structure is not required. Positioning can be performed directly using the impact-resistant structure, effectively combining the impact-resistant structure and the first positioning structure into one. Of course, the impact-resistant structure and the first positioning structure can also be provided simultaneously. If the connector is not equipped with an impact-resistant structure, it is preferred that the first positioning structure be provided.

[0052] In any of the above technical solutions, preferably, the number of the first positioning structures is multiple, and the number of the second positioning structures is consistent with the number of the first positioning structures.

[0053] In these technical solutions, the number of the first positioning structures and the number of the second positioning structures are preferably multiple, so that multiple positioning can be achieved to ensure the reliability of positioning.

[0054] In any of the above technical solutions, preferably, the first positioning structure is one of a positioning post and a positioning hole, and the second positioning structure is the other of the positioning post and the positioning hole, and the positioning post can be inserted and installed in the positioning hole.

[0055] In these technical solutions, the first positioning structure is preferably a positioning post or a positioning hole. In this case, the second positioning structure is the other of the positioning post and the positioning hole. In this way, the positioning between the connector and the electronic control board can be achieved through the plug-in fit of the positioning post and the positioning hole. Preferably, the first positioning structure is the positioning hole, and the second positioning structure is the positioning post.

[0056] In any of the above technical solutions, preferably, the positioning column is a circular column, and the positioning hole is a circular hole that is compatible with the circular column.

[0057] In these technical solutions, the positioning column is preferably a circular column, and the positioning hole is preferably a circular hole that matches the circular column, because the circular structure is more common and thus easier to process.

[0058] An embodiment of the second aspect of the present invention provides an electric heating appliance, comprising: an appliance assembly; a bottom cover mounted to the appliance assembly; and an electric control board assembly provided by any embodiment of the first aspect, the electric control board assembly being arranged between the bottom cover and the appliance assembly.

[0059] According to an embodiment of the present invention, an electric heating device includes a bottom cover, the electric heating device, and an electric control board assembly. The bottom cover is preferably installed at the bottom of the device assembly, and the electric control board assembly is disposed between the bottom cover and the device assembly and can be installed on either the device assembly or the bottom cover. Furthermore, the connector of the electric control board assembly can partially extend out of the bottom cover to facilitate electrical connection with the base assembly. Furthermore, since the electric heating device provided by an embodiment of the present invention includes the electric control board assembly provided by any embodiment of the first aspect, the electric heating device provided by an embodiment of the present invention has all the beneficial effects of the electric control board assembly provided by any embodiment of the first aspect, which are not listed here one by one.

[0060] In one embodiment, the electronic control board assembly is mounted on the bottom cover and assembled integrally with the bottom cover. During installation, the connector and electronic control board can be assembled first, and then assembled integrally with the bottom cover. Finally, the bottom cover, connector, and electronic control board assembly can be assembled onto the appliance assembly. In another embodiment, the electronic control board assembly is mounted on the appliance assembly. In this case, the electronic control board assembly can be mounted first on the bottom of the appliance assembly, and then the bottom cover can be mounted onto the bottom of the appliance assembly.

[0061] In any of the above technical solutions, preferably, the projection of the electric control board assembly on the appliance assembly is located within an area centered on the center of the appliance assembly.

[0062] In these technical solutions, the electric control board assembly can be installed at the center of the bottom of the appliance assembly. In this way, when the electric heating appliance and the base assembly are powered, the electric heating appliance can be connected to the power supply on the base assembly through the middle of the electric heating appliance. Of course, the electric control board assembly can also be installed on the edge of the bottom of the appliance assembly.

[0063] In any of the above technical solutions, preferably, the electric heating device further comprises: a bracket installed at the bottom of the device assembly; wherein the bottom cover is installed on the bracket, and the electric control board assembly is installed on a side of the bracket close to the bottom cover.

[0064] In these technical solutions, a bracket may be provided at the bottom of the appliance assembly so that the electrical control panel assembly, the bottom cover, etc. can be installed with the appliance assembly through the bracket.

[0065] In one embodiment, the bracket can be mounted directly to the bottom of the appliance assembly, and then the electrical control board assembly and bottom cover can be mounted on the bracket. Alternatively, the electrical control board assembly and bottom cover can be assembled as a whole before being mounted on the bracket. In another embodiment, the bracket can be mounted directly to the bottom cover, and then the bottom cover, electrical control board assembly, and bracket can be assembled as a whole before being mounted on the bottom of the appliance assembly.

[0066] In any of the above technical solutions, preferably, the bracket includes: a bracket plate, located between the appliance assembly and the electric control board assembly; a first structure, arranged on the bracket plate, for fixing the bracket plate to the appliance assembly, and / or a second structure, arranged on the bracket plate, and the bottom cover can be mounted on the bracket plate through the second structure; a third structure, arranged on the bracket plate, for mounting the electric control board assembly.

[0067] In these technical solutions, the bracket includes a bracket plate, a first structure, a second structure, and a third structure. The bracket plate can be connected to the appliance assembly via the first structure, while the bottom cover is installed on the bracket plate via the second structure. The third structure is used to install the electric control board assembly and the bracket. This structure allows the bracket to be used to install parts such as the appliance assembly, the bottom cover, and the electric control board assembly. That is, by providing the bracket, the surrounding parts of the bracket, such as the appliance assembly, the bottom cover, and the electric control board assembly, can be integrated and installed together. This makes the bottom structure of the appliance assembly more compact, thereby reducing the space occupied by surrounding parts such as the bottom cover and the electric control board assembly at the bottom of the appliance assembly, and achieving miniaturization of electric heating appliances such as kettles. At the same time, during installation, this structure can fix corresponding parts in corresponding positions through corresponding structures, thereby achieving sequential assembly, which can simplify the product assembly process, improve the product assembly convenience, and thus reduce the product cost.

[0068] The first structure and the second structure are preferably provided at the same time, but only one may be provided.

[0069] In any of the above technical solutions, preferably, the electric heating device further includes a detection element that can be connected to the electric control board, and the bracket further includes: a fourth structure, provided on the bracket plate, for mounting the detection element.

[0070] In this technical solution, when the electric heating device also includes a temperature, pressure, or liquid level detection element, a corresponding fourth structure can be provided on the bracket to facilitate mounting of the detection element on the bracket. The detection element can be used to detect parameters such as temperature, pressure, or liquid level of the device assembly, so that the temperature, pressure, or liquid level parameters of the electric heating device can be readily monitored during operation. The detection element can then be connected to an electronic control board, allowing the board to control subsequent product operations based on these parameters.

[0071] In another embodiment, the detection element may be installed directly on the instrument assembly instead of on the bracket plate. In this case, there is no need to set up a structure for installing the detection element on the bracket plate, and the detection element may preferably be installed on the instrument assembly by screws.

[0072] In any of the above technical solutions, preferably, the detection element includes a pressure sensor and / or a temperature sensor.

[0073] In these technical solutions, the detection element may preferably be a temperature sensor, which can detect temperature and thus control the product based on the temperature of the appliance component. Of course, the detection element may also be a pressure sensor, which can detect pressure and thus control the product based on the pressure of the appliance component. Of course, the detection element may also be other components capable of detecting container parameters, such as a liquid level sensor.

[0074] The temperature sensor and other detection elements may be mounted on the substrate of the electronic control board in a manner such as fixed connection, connection with a soft body such as silicone, or elastic connection such as a spring.

[0075] Wherein, preferably, the detection element is a thermistor.

[0076] In any of the above technical solutions, preferably, the fourth structure includes a threaded connector, and the detection element is installed on the bracket plate through the threaded connector, or the fourth structure includes a mounting groove and an elastic fixing member installed in the mounting groove, and the detection element is installed on the elastic fixing member.

[0077] In these technical solutions, screws, threaded holes, and other structures can be provided on the bracket plate so that detection elements such as temperature sensors can be threadedly mounted on the bracket plate through the screws, threaded holes, and other structures. Furthermore, mounting grooves can be provided on the bracket plate, and elastic fixings can be provided within the mounting grooves. The temperature sensor and other detection elements can then be mounted on the elastic fixings. The provision of elastic fixings can reduce vibration of the detection elements and improve their safety.

[0078] In any of the above technical solutions, preferably, the elastic fixing member is a spring, silicone or rubber, and a slot is provided on the elastic fixing member, and the detection element is installed in the slot.

[0079] In these technical solutions, the elastic fixing member may preferably be a relatively common and elastic part such as a spring, silicone or rubber. In this case, a card slot may be provided on the elastic fixing member so that a detection element such as a temperature sensor can be clipped into and installed on the elastic fixing member. Preferably, the detection element such as the temperature sensor is installed in the card slot with interference fit, so that the detection element such as the temperature sensor can be installed more tightly to prevent the detection element such as the temperature sensor from falling off the bracket plate. Of course, the detection element such as the temperature sensor may also be installed in the card slot without interference fit. In this case, the detection element such as the temperature sensor can be pressed down by the bracket plate and the device assembly to achieve the fixation of the detection element such as the temperature sensor.

[0080] In any of the above technical solutions, preferably, the detection element includes a temperature sensor, and the temperature sensor is arranged in a low temperature area of the device assembly.

[0081] In these technical solutions, a heating device for heating is provided at the bottom of the appliance assembly, and the specific structure of the heating device can be a heating tube or a heating plate. However, regardless of whether it is a heating plate or a heating tube, the heating component is generally a tubular structure. When the tubular structure is coiled and arranged at the bottom of the appliance assembly, it cannot be evenly distributed at the bottom of the appliance assembly, thereby forming a high-temperature zone and a low-temperature zone at the bottom of the appliance assembly. The low-temperature zone is the area at the bottom of the appliance assembly where no heating tube is provided or the area is relatively far from the heating tube, while the high-temperature zone is the area of the appliance assembly directly corresponding to the heating tube, that is, the area where the heating tube is provided or the area very close to the heating tube. When the detection element includes a temperature sensor, it is preferred that the temperature sensor be installed in the low-temperature zone of the appliance assembly so that the temperature sensor can avoid the high-temperature zone of the appliance assembly. This can reduce the influence of the heating device on the temperature sensor, thereby ensuring the temperature measurement accuracy of the temperature sensor.

[0082] Among them, when the heating device is a heating tube, the low temperature zone of the electric heating appliance is the same as the low temperature zone of the appliance assembly, and when a heating plate is provided at the bottom of the appliance assembly and a heating tube is provided at the bottom of the heating plate, the bracket and the like can be installed on the heating plate, and at this time the low temperature zone of the appliance assembly is the low temperature zone of the heating plate, and at this time detection elements such as temperature sensors are installed in the low temperature zone of the heating plate.

[0083] In any of the above technical solutions, preferably, the electric heating device further includes a temperature fuse or a temperature switch, and the bracket further includes: a fifth structure, provided on the bracket plate, for mounting the temperature fuse or the temperature switch.

[0084] In these technical solutions, a temperature fuse or temperature switch can be installed on the bracket board to provide overheat protection. This allows for dual temperature control via the electrical control board and the temperature fuse or temperature switch, allowing the product to automatically shut down when the temperature is too high. The temperature fuse can be configured with a fuse that blows when the temperature exceeds a certain value, providing overheat protection.

[0085] Preferably, the fifth structure is a limiting groove, and the temperature fuse or the temperature switch is installed in the installation groove. Of course, the fifth structure can also be set to other structures.

[0086] In any of the above technical solutions, preferably, the first structure includes a plurality of fixing holes arranged on the bracket plate, and the bracket plate is fixedly installed to the appliance assembly through the plurality of fixing holes; the second structure includes a plurality of mounting columns arranged on the bracket plate, and the mounting columns are provided with mounting holes, and the bottom cover is installed on the bracket plate through the plurality of mounting columns.

[0087] In these technical solutions, multiple fixing holes can be provided on the bracket plate, and then screws or bolts can be used to fit into the fixing holes to achieve the installation between the bracket plate and the appliance assembly. Furthermore, multiple mounting posts can be provided on the bracket plate, and mounting holes can be provided on the mounting posts. During installation, the bottom cover can be mounted on the mounting posts, for example, by screws or bolts.

[0088] In any of the above technical solutions, preferably, the number of the mounting posts is consistent with the number of the fixing holes, and / or each of the fixing holes is correspondingly arranged around one of the mounting posts.

[0089] In these technical solutions, the number of mounting posts and fixing holes is preferably equal, but of course, the number of mounting posts and fixing holes may be unequal. Furthermore, since providing fixing holes on the bracket plate weakens the bracket plate at the fixing holes, while providing mounting posts on the bracket plate strengthens the bracket plate at the mounting posts, it is preferred that each fixing hole be provided around a corresponding mounting post, i.e., the fixing holes be provided next to the mounting posts. This allows the weaker and stronger parts of the bracket plate to be closer together, thereby enhancing the overall strength of the bracket plate.

[0090] Preferably, the minimum distance between the fixing hole and the mounting post is less than or equal to 10 mm. More preferably, the minimum distance between the fixing hole and the mounting post is less than or equal to 6 mm. For example, the minimum distance between the fixing hole and the mounting post can be set to 5 mm, 3 mm, 2 mm, or 1 mm. Of course, the minimum distance between the fixing hole and the mounting post can also be set to 7 mm or 8 mm.

[0091] In any of the above technical solutions, preferably, the bracket is mounted to the bottom of the appliance assembly via fasteners.

[0092] In these technical solutions, when installing the bracket, it is preferred to use fasteners such as screws to achieve the installation between the bracket and the device assembly, because the screwing method is easy to operate, reliable to install and inexpensive.

[0094] In these technical solutions, the support plate includes a base plate and a surrounding plate. These base plate and surrounding plate form a storage space for accommodating and installing components such as the electronic control panel assembly. The surrounding plate limits the installation boundaries of these components and also provides support for other objects to prevent them from squeezing other components within the storage space. Preferably, the surrounding plate is arranged in an annular shape, i.e., arranged in a circle around the base plate.

[0095] In any of the above technical solutions, preferably, at least one reinforcing rib is provided on the other side of the base plate, wherein one side of the base plate is one of the back side of the base plate and the front side of the base plate, and the other side of the base plate is the other of the back side of the base plate and the front side of the base plate.

[0096] In these technical solutions, the enclosure plate may preferably be set on one side of the bracket plate, such as the front side. At this time, one or more reinforcing ribs may be set on the back side of the bracket plate to enhance the strength of the bracket plate and prevent deformation due to insufficient strength of the bracket plate.

[0097] In any of the above technical solutions, preferably, the bracket is a high temperature resistant part.

[0098] In these technical solutions, the bracket is a high-temperature resistant bracket, which can improve the heat resistance of the bracket and prevent the bracket from deforming under high-temperature conditions.

An impact-resistant structure is provided on the bottom wall of the receiving groove and one of the connectors, and the impact-resistant structure can pass through the avoidance hole and cooperate with the bottom wall of the receiving groove and the other of the connectors.

[0100] In these technical solutions, a receiving groove can be provided on the bracket plate to facilitate installation of the electric control board on the bracket plate, that is, the electric control board assembly can be directly installed in the receiving groove. At the same time, an impact-resistant structure can be provided on the bottom of the receiving groove to facilitate positioning and installation between the bracket plate and the electric control board assembly. During installation, the connector can be preferably assembled on the side of the electric control board close to the bottom cover, and a relief hole can be provided on the connector. During installation, the impact-resistant structure can be extended from the relief hole and then abutted against or fixed to the connector. In this way, after the electric control board assembly is installed, the impact-resistant structure can pass through the electric control board and form a support on the other side of the electric control board, thereby preventing the bracket plate, bottom cover, etc. from directly squeezing the electric control board. This can improve the stress on the electric control board and reduce the probability of the electric control board being squeezed and damaged during use. Of course, in another solution, the impact-resistant structure can also be provided on the connector, and then pass through the relief hole to form a support with the bracket, which can also prevent the bracket plate, bottom cover, etc. from directly squeezing the electric control board.

The container is used to hold food such as water, and the heating device is used to heat and cook the food within the container. The electrical control board assembly is used to supply power to the heating device and other components of the appliance assembly and to detect the temperature of the container. Furthermore, if the electrical control board assembly also includes an electrical control board, the electrical control board assembly can also control the power supply to the heating device and other components via the electrical control board.

[0105] In these technical solutions, the electric heating device also includes a shell, in which an appliance assembly is arranged. In this structure, the appliance assembly is used to directly contact the food, and the shell is used to protect the appliance assembly and to insulate the appliance assembly to prevent heat from escaping from the appliance assembly. The operation display panel is used to display the content that the electric heating device needs to display, such as temperature, working status, etc., and is used to specifically control the operation of the product. For example, operation buttons can be set on the operation display panel, so that the corresponding operation buttons can be used to control the product to work according to the corresponding workflow or program. Among them, the operation display panel here is connected to the electric control board, so that the instructions issued by the user through the operation display panel can be transmitted to the electric control board, so that the electric control board can perform corresponding controls according to the user's operation.

By providing a handle on the outer shell, the user can use the handle to move the entire electric heating appliance, and by providing a container lid, the container body can be opened and closed. Signal transmission between the operation display panel and the electronic control board is preferably effectively transmitted via wires, but wireless transmission can also be achieved through a wireless module, which is not specifically limited here.

DETAILED DESCRIPTION

[0139] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0140] In the following description, many specific details are set forth to facilitate 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.

[0141] Refer to the following Figures 1 to 24 The electric control panel assembly 1, the electric heating appliance and the electric heating device provided according to some embodiments of the present invention are described.

[0142] like Figures 1 to 7 As shown, an embodiment of the first aspect of the present invention provides an electric control board assembly 1 for an electric heating appliance, the electric heating appliance including an appliance assembly, wherein the electric control board assembly 1 includes an electric control board 12 and a connector 14, the connector 14 includes a plurality of power connectors for connecting electricity, the connector 14 is assembled into one with the electric control board 12, and after the connector 14 is assembled into one with the electric control board 12, it can be installed to the appliance assembly and control the operation of the appliance assembly.

[0143] The electric control board assembly 1 provided according to an embodiment of the present invention can be specifically used in electric heating appliances such as kettles, and preferably in electronic electric heating appliances such as electronic kettles. The electric control board assembly 1 includes an electric control board 12 and a connector 14, which are integrally assembled. The electric control board 12 can be used to control the operation of the electric heating appliance, such as controlling whether the product is powered on or off, such as controlling whether the heating device 34 is powered on or off, based on the temperature detected by a temperature sensor. Of course, the electric control board 12 can also be used to control other functions of the product. The connector 14 is primarily used to connect to another power connection device 52 or an external power source to power the electric heating appliance. For example, the connector 14 can be connected to the power connection device 52 on the base assembly 5 of the electric heating device, so that electricity from the base assembly 5 can be introduced to the appliance assembly of the electric heating appliance via the power connection device 52 and the connector 14. Specifically, the power connections on the connector 14 can include a positive terminal 142 connected to the live wire and a negative terminal 144 connected to the neutral wire. The electric control board assembly 1 provided by this structure assembles the connector 14 and the electric control board 12 into a whole, realizing the modularization of multiple scattered parts, so that the electric control board assembly 1 can integrate control, power connection and other functions into one. In this way, when in specific use, the electric control board assembly 1 can be assembled as a whole first, and then the electric control board assembly 1 can be installed as a whole on the kettle body or other appliance components of the electric heating appliance. In this way, the structure of the product can be optimized, and the space occupied by the electric control board assembly 1 at the bottom of the kettle body or other appliance components can be reduced, solving the problem in the prior art that the electric control board 12 and the existing connector 14 are both independent parts and are both arranged at the bottom of the kettle body or other appliance components, which makes the structure of the bottom of the kettle body or other appliance components more complicated and inconvenient to install. At the same time, this structure only requires the electronic control board assembly 1 to be installed as a whole on the kettle body or other appliance components, so there is no need to install the connector 14 and the electronic control board 12 on the bottom of the kettle body or other appliance components in multiple steps. This can simplify the installation steps of the product, improve installation efficiency, reduce manpower, thereby reducing the production cost of the product, and solving the problem of excessively high production costs of products such as electronic kettles.

[0144] When the connector 14 and the electric control board 12 are assembled into one, they can be assembled into a detachable structure in a detachable manner, or they can be assembled into an integral structure that cannot be disassembled by welding or other methods. In this application, assembling multiple parts into one means assembling multiple parts into a whole, rather than connecting multiple parts in an integral manner. At the same time, when the electric control board 12 is connected to the connector 14, the connector 14 can be directly rigidly connected to the electric control board 12, for example, Figure 23 As shown, the connection is made by a rigid connector 9a such as metal, or as Figure 24As shown, a connecting line 9 b is provided between the electric control board 12 and the connector 14 so as to realize a non-rigid connection between the electric control board 12 and the connector 14 through the connecting line 9 b.

[0145] In any of the above embodiments, preferably, Figure 1 and Figure 2 As shown, the electric control board 12 includes a substrate 122 and an electric control device (which can be specifically Figure 1 and Figure 2 The relay 124 in the circuit board is mounted on the substrate 122 , and the connector 14 is mounted on the substrate 122 .

[0146] In these embodiments, the electronic control board 12 includes a substrate 122 and an electrical control component. The substrate 122 is used to implement control operations, mount other components, and integrate circuits. The electrical control component is preferably a relay 124, which can control the power supply of the product. The connector 14 can be directly assembled on the substrate 122.

[0147] In any of the above embodiments, preferably, Figure 21 As shown, the electric control board assembly 1 further includes: a detection element, which is installed on the substrate 122 and connected to the electric control device; wherein the electric control board 12, the connector 14 and the detection element are assembled into one body.

[0148] In these embodiments, the detection element can be specifically used to detect parameters such as the temperature, pressure, or liquid level of the appliance component such as the kettle body, so that the temperature, pressure, or liquid level parameters such as the electric heating appliance can be known at any time during operation, so that the electronic control board 12 can perform subsequent product operation control based on these parameters. The electronic control board assembly 1 provided by this structure assembles the connector 14, the detection element, and the electronic control board 12 into an integral whole, realizing the modularization of multiple discrete components, thereby enabling the electronic control board assembly 1 to integrate functions such as control, power connection, and temperature measurement. In actual use, the electronic control board assembly 1 can be assembled first, and then installed as a whole on the appliance component such as the kettle body of the electric heating appliance. This can optimize the product structure and reduce the space occupied by the electronic control board assembly 1 at the bottom of the appliance component such as the kettle body, thereby solving the problem that the electronic control board 12, the thermostat, and the existing connector 14 are all independent parts and are all arranged at the bottom of the appliance component such as the kettle body, which makes the bottom structure of the appliance component such as the kettle body relatively complicated and inconvenient to install.

[0149] Preferably, the detection element includes a pressure sensor and / or a temperature sensor.

[0150] In these embodiments, the detection element may preferably be a temperature sensor, which can detect temperature so that the product can be controlled based on the temperature of the kettle body or other appliance components. Of course, the detection element may also be a pressure sensor, which can detect pressure so that the product can be controlled based on the pressure of the kettle body or other appliance components. Of course, the detection element may also be other components capable of detecting container parameters, such as a liquid level sensor.

[0151] The detection elements such as the temperature sensor are mounted on the substrate 122 of the electronic control board 12 by a fixed connection, a connection with a soft body such as silicone, or an elastic connection such as a spring.

[0152] More preferably, Figures 3 to 5 As shown, the multiple electrical connectors include a positive connector 142 and a negative connector 144 . The positive connector 142 and the negative connector 144 are both welded or riveted to the substrate 122 , or the positive connector 142 and the negative connector 144 are both plugged and installed on the substrate 122 .

[0153] In these embodiments, the positive and negative connectors 142, 144 can form a power supply circuit with the live and neutral wires in the user's home. The positive and negative connectors 142, 144 can be mounted to the base plate 122 using any conventional mounting method. Preferably, the positive and negative connectors 142, 144 are riveted or welded to the base plate 122, as these methods are more reliable and easier to operate. Of course, the positive and negative connectors 142, 144 can also be mounted to the base plate 122 using snaps, screws, or plug-ins. Soldering is preferred for welding, while plug-in connections are preferably made using terminal blocks 168.

[0156] In any of the above embodiments, preferably, the electric control board 12 is a PCB board.

[0157] In these embodiments, the electronic control board 12 is preferably a PCB board, because the PCB board is a common electronic control component, and thus it is relatively common and easier to purchase.

This allows the grounding structure 146 to be connected to the appliance assembly via the first conductive connector 126, thereby grounding the appliance assembly. In another embodiment, a second conductive connector 8 can be positioned directly between the appliance assembly and the grounding structure 146 to achieve a connection between the appliance assembly and the grounding structure 146. In this case, the second conductive connector 8 can be positioned on the electrical control board 12 or independently of the electrical control board 12. Alternatively, the second conductive connector 8 can be positioned on the connector 14 and connected to the appliance assembly. Furthermore, the grounding structure 146 can be mounted directly to the appliance assembly for grounding. For example, an extension structure 1462 can be positioned on the grounding structure 146 and then secured to the appliance assembly via the first fastener 6.

Preferably, the grounding structure 146 may be configured as the innermost layer, the negative terminal 144 as the outermost layer, and the positive terminal 142 as the middle layer.

The type of grounding structure 146 can be selected based on actual needs. Preferably, the grounding structure 146 is a grounding wire, that is, the grounding structure 146 is preferably a grounding wire. This can make the grounding structure 146 simpler, thereby reducing product costs. Preferably, the grounding structure 146 is mounted on the electronic control board 12 by riveting or welding.

[0174] In these embodiments, the innermost layer of the three-layer structure may be preferably provided as the grounding structure 146. In this case, the extension structure 1462 may first extend from the bottom of the grounding structure 146 and then extend to the side of the connector 14. Of course, the extension structure 1462 may also be extended from the bottom to the top so that the extension structure 1462 can be fixedly mounted to the bottom of a device component such as a kettle body.

[0175] More preferably, the grounding structure 146 is a copper structure.

[0176] In any of the above embodiments, preferably, Figure 8As shown, extension structure 1462 is mounted on the appliance assembly via a threaded connector. With this arrangement, extension structure 1462 can be mounted on the appliance assembly via threaded connectors, such as screws or bolts. Preferably, holes are pre-drilled in extension structure 1462 to facilitate installation with screws or bolts. Alternatively, holes can be drilled in extension structure 1462 during installation to facilitate installation with screws or bolts. Alternatively, self-tapping screws can be used to mount extension structure 1462 to the appliance assembly, eliminating the need for drilling holes in extension structure 1462. Furthermore, extension structure 1462 can also be configured as a wire.

[0177] In any of the above embodiments, preferably, the electric control board assembly 1 further includes: a fuse (not shown in the figures), which is arranged on the connector 14 or on the electric control board 12 .

[0178] In these embodiments, the fuse automatically disconnects when the current exceeds its limit value, thereby preventing excessive current from flowing through the electrical control board 12. Thus, the provision of the fuse provides current limiting protection for the electrical control board 12. Specifically, the fuse can be mounted on the connector 14 or the electrical control board 12 by screwing, riveting, welding, elastic connection, snap-fit connection, or other connection methods.

[0179] In any of the above embodiments, preferably, Figures 1 to 7 As shown, the connector 14 is assembled on one side of the electric control board 12. Figure 12 As shown, an avoidance hole is provided on the electric control board 12 , and an impact-resistant structure 148 is provided on the connector 14 , and the impact-resistant structure 148 can pass through the avoidance hole.

[0180] In these embodiments, when the connector 14 and the electric control board 12 are assembled, the connector 14 can be installed on the side of the electric control board 12 away from the appliance assembly, and by providing an avoidance hole on the electric control board 12 and providing an impact-resistant structure 148 on the connector 14, after the connector 14 and the electric control board 12 are assembled into a whole, the impact-resistant structure 148 on the connector 14 can pass through the electric control board 12 and form a support on the other side of the electric control board 12. In this way, after the electric control board assembly 1 is installed as a whole on an appliance assembly such as a kettle body, the impact-resistant structure 148 can support the appliance assembly such as the kettle body, thereby preventing the appliance assembly such as the kettle body from directly squeezing the electric control board 12. In this way, the force applied to the electric control board 12 can be improved, and the possibility of the electric control board 12 being squeezed and damaged during use can be reduced.

[0181] In any of the above embodiments, preferably, the impact-resistant structure 148 is a plastic structure, a metal structure, a rubber structure, or a silicone structure.

[0182] In these embodiments, the impact-resistant structure 148 may be a plastic structure, a rubber structure, a silicone structure, or a metal structure, etc., as long as it can withstand a certain pressure. However, the impact-resistant structure 148 may preferably be a softer structure such as plastic, rubber, or silicone, so that it can form a certain buffer against the impact force and improve the impact resistance of the impact-resistant structure 148.

[0183] In any of the above embodiments, preferably, a first positioning structure is provided on the connector 14 and a second positioning structure is provided on the electric control board 12 , and the connector 14 is mounted on the electric control board 12 through the cooperation between the first positioning structure and the second positioning structure.

[0184] In these embodiments, a first positioning structure may be provided on the connector 14, while a second positioning structure may be provided on the electric control board 12. This allows the first and second positioning structures to cooperate to achieve preliminary positioning of the connector 14 on the electric control board 12. After this preliminary positioning, the positive terminal 142 and the negative terminal 144 of the connector 14 can be directly connected to the electric control board 12. This preliminary positioning can secure the positions of the electric control board 12 and the connector 14 in advance, preventing the positive terminal 142 and the negative terminal 144 of the connector 14 from moving when connected to the electric control board 12.

[0185] When the impact-resistant structure 148 is provided on the connector 14, the first positioning structure is not required. In this case, the impact-resistant structure 148 can be used directly for positioning, that is, the impact-resistant structure 148 and the first positioning structure can be combined into one. Of course, the impact-resistant structure 148 and the first positioning structure can also be provided simultaneously. If the impact-resistant structure 148 is not provided on the connector 14, it is preferred that the first positioning structure be provided on the connector 14.

[0186] In any of the above embodiments, preferably, the number of the first positioning structures is plural, and the number of the second positioning structures is the same as the number of the first positioning structures.

[0187] In these embodiments, the number of the first positioning structures and the number of the second positioning structures are preferably multiple, so that multiple positioning can be achieved to ensure the reliability of positioning.

[0188] In any of the above embodiments, preferably, the first positioning structure is one of the positioning column 464 and the positioning hole, and the second positioning structure is the other of the positioning column 464 and the positioning hole, and the positioning column 464 can be inserted and installed in the positioning hole.

[0189] In these embodiments, the first positioning structure is preferably a positioning post 464 or a positioning hole. In this case, the second positioning structure is the other of the positioning post 464 and the positioning hole. In this way, the positioning between the connector 14 and the electronic control board 12 can be achieved through the plug-in fit between the positioning post 464 and the positioning hole. Preferably, the first positioning structure is the positioning hole, and the second positioning structure is the positioning post 464.

[0190] In any of the above embodiments, preferably, the positioning column 464 is a circular column, and the positioning hole is a circular hole that matches the circular column.

[0191] In these embodiments, the positioning column 464 is preferably a circular column, and the positioning hole is preferably a circular hole that matches the circular column, because circular structures are more common and therefore easier to process.

[0193] The electric heating appliance provided in accordance with an embodiment of the present invention comprises a bottom cover 2, the electric heating appliance, and an electric control board assembly 1. The bottom cover 2 is preferably mounted on the bottom of the appliance assembly, while the electric control board assembly 1 is disposed between the bottom cover 2 and the appliance assembly and can be mounted on either the appliance assembly or the bottom cover 2. Furthermore, since the electric heating appliance provided in accordance with an embodiment of the present invention comprises the electric control board assembly 1 provided in any embodiment of the first aspect, the electric heating appliance provided in accordance with an embodiment of the present invention possesses all the beneficial effects of the electric control board assembly 1 provided in any embodiment of the first aspect, which are not enumerated here.

Finally, the bottom cover 2, the connector 14 and the electric control board 12 can be assembled to the appliance assembly. In another embodiment, the electric control board assembly 1 is installed on the appliance assembly. In this case, the electric control board assembly 1 can be installed on the bottom of the appliance assembly first, and then the bottom cover 2 can be installed on the bottom of the appliance assembly. In addition, during the specific installation, it is also possible to first install the electric control board assembly as shown in FIG. Figure 15 As shown, the connector 14 and the bottom cover 2 are assembled into a whole.

[0195] In any of the above embodiments, preferably, Figures 8 to 12 as well as Figure 21As shown, the projection of the electric control panel assembly 1 on the appliance assembly is located within an area centered on the center of the appliance assembly.

[0196] In these embodiments, the electric control board assembly 1 can be installed at the center of the bottom of the appliance assembly. In this way, when the electric heating appliance and the base assembly 5 are powered on, the electric control board assembly 1 can be connected to the power supply on the base assembly 5 through the middle of the electric heating appliance. Of course, the electric control board assembly 1 can also be installed on the edge of the bottom of the appliance assembly.

[0197] In any of the above embodiments, preferably, Figure 16 As shown, the electric heating appliance further includes: a bracket 4 installed at the bottom of the appliance assembly; wherein, the bottom cover 2 is installed on the bracket 4, and the electric control board assembly 1 is installed on a side of the bracket 4 close to the bottom cover 2.

[0198] In these embodiments, a bracket 4 may be provided at the bottom of the appliance assembly so that the electrical control board assembly 1 , the bottom cover 2 , etc. can be installed with the appliance assembly through the bracket 4 .

[0199] In one embodiment, the bracket 4 can be directly mounted to the bottom of the appliance assembly, and then the electric control board assembly 1 and bottom cover 2 can be mounted on the bracket 4. Of course, the electric control board assembly 1 and bottom cover 2 can also be assembled into a whole before being mounted on the bracket 4. In another embodiment, the bracket 4 can also be directly mounted to the bottom cover 2, and then the bottom cover 2, electric control board assembly 1, and bracket 4 can be assembled into a whole before being mounted on the bottom of the appliance assembly.

[0201] In these embodiments, the bracket 4 includes a bracket plate 40, a first structure, a second structure, and a third structure 46. The bracket plate 40 is connected to the appliance assembly via the first structure, while the bottom cover 2 is mounted on the bracket plate 40 via the second structure. The third structure 46 is used to mount the electrical control board assembly 1 to the bracket 4. This structure allows the bracket 4 to facilitate the installation of components such as the appliance assembly, bottom cover 2, and electrical control board assembly 1. Specifically, the bracket 4 allows the appliance assembly, bottom cover 2, and electrical control board assembly 1, along with other components surrounding the bracket 4, to be integrated and mounted together. This makes the bottom structure of the appliance assembly more compact, thereby reducing the space occupied by surrounding components such as the bottom cover 2 and electrical control board assembly 1, and achieving miniaturization of electric heating appliances such as kettles. Furthermore, during installation, this structure allows corresponding components to be fixed in their respective positions via corresponding structures, enabling sequential assembly. This simplifies the product assembly process, improves product assembly convenience, and reduces product cost.

[0202] The first structure and the second structure are preferably provided at the same time, but only one may be provided.

[0203] In any of the above embodiments, preferably, Figure 17 、 Figure 18 and Figure 21 As shown, the electric heating device also includes a detection element (which can be specifically Figure 21 The sensor 16 in the bracket 4 further includes: a fourth structure 48, which is provided on the bracket plate 40 and is used to install the detection element.

[0204] In this embodiment, when the electric heating device also includes a temperature, pressure, or liquid level detection element, a corresponding fourth structure 48 may be provided on the bracket 4 to facilitate mounting of the detection element on the bracket 4. The detection element may be used to detect parameters such as temperature, pressure, or liquid level of the device assembly, thereby enabling timely monitoring of the temperature, pressure, or liquid level parameters of the electric heating device during operation. The detection element may then be connected to the electronic control board 12 so that the electronic control board 12 can control subsequent product operation based on these parameters.

[0205] In another embodiment, the detection element may be installed directly on the instrument assembly instead of on the bracket plate 40. In this case, there is no need to set up a structure for installing the detection element on the bracket plate 40, and the detection element may preferably be installed on the instrument assembly by screws.

[0206] Preferably, the detection element includes a pressure sensor and / or a temperature sensor.

[0207] In these embodiments, the detection element may preferably be a temperature sensor, which can detect temperature so that the product can be controlled based on the temperature of the appliance component. Of course, the detection element may also be a pressure sensor, which can detect pressure so that the product can be controlled based on the pressure of the appliance component. Of course, the detection element may also be other components capable of detecting container parameters, such as a liquid level sensor.

[0208] The detection elements such as the temperature sensor are mounted on the substrate 122 of the electronic control board 12 by a fixed connection, a connection with a soft body such as silicone, or an elastic connection such as a spring.

[0209] Wherein, preferably, the detection element is a thermistor.

[0210] In any of the above embodiments, preferably, Figure 17 and Figure 18 As shown, the fourth structure 48 includes a threaded connector, and the detection element is mounted on the bracket plate 40 via the threaded connector, or the fourth structure 48 includes a mounting groove 482 and an elastic fixing member 484 installed in the mounting groove 482, and the detection element is mounted on the elastic fixing member 484.

[0211] In these embodiments, screws, threaded holes, and other structures may be provided on the support plate 40 so that detection elements such as temperature sensors can be threadedly mounted on the support plate 40 through the screws, threaded holes, and other structures. Furthermore, a mounting groove 482 may be provided on the support plate 40, and an elastic fixing member 484 may be provided within the mounting groove 482. Then, a detection element such as a temperature sensor may be mounted on the elastic fixing member 484. The provision of the elastic fixing member 484 can reduce vibration of the detection element and improve its safety.

[0212] More preferably, Figure 21 As shown, the elastic fixing member 484 is a spring or silicone or rubber, and a slot 4842 is provided on the elastic fixing member 484 , and the detection element is installed in the slot 4842 .

[0213] In these embodiments, the elastic fixing member 484 may preferably be a relatively common and elastic part such as a spring, silicone, or rubber. In this case, a card slot 4842 may be provided on the elastic fixing member 484 so that a detection element such as a temperature sensor can be clipped into and installed on the elastic fixing member 484. Preferably, the detection element such as the temperature sensor is installed in the card slot 4842 with an interference fit, so that the detection element such as the temperature sensor can be installed more tightly and prevent the detection element such as the temperature sensor from falling off the bracket plate 40. Of course, the detection element such as the temperature sensor can also be installed in the card slot 4842 without interference fit. In this case, the detection element such as the temperature sensor can be pressed by the bracket plate 40 and the device assembly to achieve the fixation of the detection element such as the temperature sensor.

[0214] In any of the above embodiments, preferably, Figure 19 and Figure 20 As shown, the detection element includes a temperature sensor, which is arranged in the low temperature area A of the instrument assembly.

[0215] In these embodiments, a heating device 34 for heating is provided at the bottom of the device assembly, and the specific structure of the heating device 34 can be a heating tube or a heating plate. However, regardless of whether it is a heating plate or a heating tube, the parts used for heating are generally tubular structures. When the tubular structure is coiled and arranged at the bottom of the device assembly, it cannot be evenly distributed at the bottom of the device assembly, thereby forming a high temperature zone and a low temperature zone A at the bottom of the device assembly. The low temperature zone A is the area at the bottom of the device assembly where no heating tube is provided or the area is relatively far from the heating tube, while the high temperature zone is the area directly corresponding to the device assembly and the heating tube, that is, the area provided at the heating tube or the area very close to the heating tube. When the detection element includes a temperature sensor, it is preferred that the temperature sensor be installed in the low temperature zone A of the device assembly so that the temperature sensor can avoid the high temperature zone of the device assembly. This can reduce the influence of the heating device 34 on the temperature sensor, thereby ensuring the temperature measurement accuracy of the temperature sensor.

[0216] Among them, when the heating device 34 is a heating tube, the low temperature zone A of the electric heating device is the same as the low temperature zone A of the device assembly, and a heating plate is provided at the bottom of the device assembly, and a heating tube is provided at the bottom of the heating plate, the bracket 4 etc. can be installed on the heating plate, and at this time the low temperature zone A of the device assembly is the low temperature zone A of the heating plate, and at this time the temperature sensor and other detection elements are installed in the low temperature zone A of the heating plate.

[0217] In any of the above embodiments, preferably, Figure 17 and Figure 18 As shown, the electric heating device further includes a temperature fuse or a temperature switch, and the bracket further includes: a fifth structure 49, which is provided on the bracket plate 40 and is used to install the temperature fuse or the temperature switch.

[0218] In these embodiments, a temperature fuse or temperature switch may be provided on the support plate 40 to provide overheat protection. This allows for dual temperature control via the electrical control panel 12 and the temperature fuse or temperature switch, allowing the product to automatically shut down when the temperature is too high. The temperature fuse may be provided with a fuse that blows when the temperature exceeds a certain value, providing overheat protection.

[0219] Among them, preferably, Figure 17 and Figure 18As shown, the fifth structure 49 is a limiting groove, and the temperature fuse or temperature switch is installed in the installation groove. Of course, the fifth structure 49 can also be set to other structures.

[0220] In any of the above embodiments, preferably, the first structure includes a plurality of fixing holes 42 provided on the bracket plate 40, and the bracket plate 40 is fixedly mounted to the appliance assembly through the plurality of fixing holes 42; the second structure includes a plurality of mounting columns 44 provided on the bracket plate 40, and the mounting columns 44 are provided with mounting holes 442, and the bottom cover 2 is mounted on the bracket plate 40 through the plurality of mounting columns 44.

[0221] In these embodiments, a plurality of fixing holes 42 can be provided on the support plate 40, and the support plate 40 and the appliance assembly can be mounted by engaging screws or bolts with the fixing holes 42. Furthermore, a plurality of mounting posts 44 can be provided on the support plate 40, each with mounting holes 442. During installation, the bottom cover 2 can be mounted on the mounting posts 44, for example, by using screws or bolts.

[0222] More preferably, Figure 17 and Figure 18 As shown, the number of the mounting posts 44 is consistent with the number of the fixing holes 42 , and / or each fixing hole 42 is correspondingly disposed around a mounting post 44 .

[0223] In these embodiments, the number of mounting posts 44 and fixing holes 42 is preferably equal. Of course, the number of mounting posts 44 and fixing holes 42 may also be unequal. At the same time, since the provision of fixing holes 42 on the bracket plate 40 weakens the bracket plate 40 at the fixing holes 42, while the provision of mounting posts 44 on the bracket plate 40 increases the strength of the bracket plate 40 at the mounting posts 44, it is preferred that each fixing hole 42 be provided around a corresponding mounting post 44, that is, the fixing holes 42 be provided next to the mounting posts 44. This allows the weaker portion of the bracket plate 40 to be closer to the stronger portion, thereby enhancing the overall strength of the bracket plate 40.

[0224] Preferably, the minimum distance between the fixing hole 42 and the mounting post 44 is less than or equal to 10 mm. More preferably, the minimum distance between the fixing hole 42 and the mounting post 44 is less than or equal to 6 mm. For example, the minimum distance between the fixing hole 42 and the mounting post 44 can be set to 5 mm, 3 mm, 2 mm, or 1 mm. Of course, the minimum distance between the fixing hole 42 and the mounting post 44 can also be set to 7 mm or 8 mm.

[0225] In any of the above embodiments, preferably, the bracket 4 is mounted to the bottom of the appliance assembly by fasteners.

[0226] In these embodiments, when specifically installing the bracket 4, it is preferred to use fasteners such as screws to achieve the installation between the bracket 4 and the device assembly, because the screwing method is easy to operate, reliable to install, and inexpensive.

[0227] In any of the above embodiments, preferably, Figure 17 and Figure 18 As shown, the bracket plate 40 includes a base plate 402 and a surrounding plate 404 . The surrounding plate 404 is arranged on one surface of the base plate 402 , and the surrounding plate 404 is arranged around the edge of the base plate 402 and is arranged in a ring shape along the circumferential direction of the base plate 402 .

[0228] In these embodiments, the support plate 40 includes a base plate 402 and a surrounding plate 404. These base plate 402 and surrounding plate 404 form a receiving space for accommodating and installing components such as the electronic control panel assembly 1. The surrounding plate 404 limits the installation boundaries of these components and also provides support for other objects, preventing them from squeezing other components within the receiving space. Preferably, the surrounding plate 404 is annular, i.e., arranged in a circle around the circumference of the base plate 402.

[0229] In any of the above embodiments, preferably, Figure 17 and Figure 18 As shown, at least one reinforcing rib 406 is provided on the other side of the base plate 402, wherein one side of the base plate 402 is one of the back side of the base plate 402 and the front side of the base plate 402, and the other side of the base plate 402 is the other of the back side of the base plate 402 and the front side of the base plate 402.

[0230] In these embodiments, the enclosure 404 may preferably be disposed on one side of the support plate 40, such as the front side. In this case, one or more reinforcing ribs 406 may be disposed on the back side of the support plate 40 to enhance the strength of the support plate 40 and prevent deformation of the support plate 40 due to insufficient strength.

[0231] In any of the above embodiments, preferably, the bracket 4 is a high temperature resistant component.

[0232] In these embodiments, the bracket 4 is a high-temperature resistant bracket, which can improve the heat resistance of the bracket 4 and prevent the bracket 4 from being deformed under high temperature conditions.

[0233] In any of the above embodiments, preferably, Figure 17 and Figure 18As shown, the third structure 46 includes a receiving groove 462 arranged on the surface of the bracket plate 40 close to the bottom cover 2, the electric control board 12 is installed in the receiving groove 462, the connector 14 is assembled on the side of the electric control board 12 away from the appliance assembly, and an avoidance hole is provided on the electric control board 12. The bottom wall of the receiving groove 462 and one of the connectors 14 are provided with an impact-resistant structure 148. The impact-resistant structure 148 can pass through the avoidance hole and cooperate with the bottom wall of the receiving groove 462 and the other of the connector 14.

[0234] In these embodiments, a receiving groove 462 may be provided on the support plate 40 to facilitate installation of the electric control board assembly 1 on the support plate 40, that is, the electric control board assembly 1 may be directly installed in the receiving groove 462. Simultaneously, an impact-resistant structure 148 may be provided on the bottom of the receiving groove 462 to facilitate positioning and installation between the support plate 40 and the electric control board assembly 1. During installation, the connector 14 may preferably be assembled on the side of the electric control board 12 close to the bottom cover 2, and a relief hole may be provided on the connector 14. During installation, the impact-resistant structure 148 may be extended from the relief hole and then abutted against or fixed to the connector 14. In this way, after the electric control board assembly 1 is installed, the impact-resistant structure 148 may pass through the electric control board 12 and form support on the other side of the electric control board 12, thereby preventing the support plate 40, the bottom cover 2, etc. from directly squeezing the electric control board 12. This improves the stress on the electric control board 12 and reduces the probability of the electric control board 12 being squeezed and damaged during use. Of course, in another solution, an impact-resistant structure 148 may be provided on the connector 14 , and then pass through the avoidance hole to form a support with the bracket 4 , which can also prevent the bracket plate 40 , the bottom cover 2 , etc. from directly squeezing the electronic control board 12 .

[0235] Preferably, if Figures 9 to 12 and Figure 21 As shown, the receiving groove 462 is surrounded by the bottom plate 402 and the surrounding plate 404 .

At the same time, when the electric control board assembly 1 also includes the electric control board 12, the electric control board assembly 1 can also control whether the heating device 34 and other components are energized or not through the electric control board 12.

[0239] In these embodiments, the electric heating device further includes a housing 36, in which an appliance assembly is disposed. In this structure, the appliance assembly is used to come into direct contact with food, and the housing 36 is used to protect the appliance assembly and to insulate the appliance assembly to prevent heat from escaping from the appliance assembly. The operation display panel 38 is used to display the content that the electric heating device needs to display, such as temperature, operating status, etc., and to specifically control the operation of the product. For example, operation buttons can be provided on the operation display panel 38, so that the corresponding operation buttons can be used to control the product to operate according to the corresponding workflow or procedure. The operation display panel 38 is connected to the electric control board 12, so that the instructions issued by the user through the operation display panel 38 can be transmitted to the electric control board 12, so that the electric control board 12 can perform corresponding control according to the user's operation.

Of course, the housing 36 can also be made of stainless steel to ensure the strength of the housing 36. The appliance assembly is preferably made of stainless steel because stainless steel is relatively stable and therefore healthier and more hygienic when in direct contact with food. By providing a handle 362 on the housing 36, the user can use the handle 362 to move the entire electric heating appliance, and by providing a container lid 39, the container body 32 can be opened and closed.
