Description

Technical Field

[0001] The present invention relates to the field of heating devices, and in particular to a temperature sensor and a heating device component. Background Art

[0002] Existing heating appliances such as induction cookers are equipped with temperature sensors for measuring the temperature of the cooker. Figure 1 As shown, during the assembly process, the temperature sensing component 10' and other parts need to be installed into the housing 20' of the temperature sensor from bottom to top, and then the temperature sensing component 10' is pressed upward by the sleeve 40', and then the limiting clamp 30' is assembled with the housing 20' and pressed upward against the sleeve 40' to limit it so that the sleeve 40' maintains the pressing of the temperature sensing component 10', preventing the temperature sensing component 10' and other parts inside the housing 20' from being pulled downward. This structure has many parts, complex assembly, and many assembly processes, which affects production efficiency. Summary of the invention

[0003] In order to solve at least one of the above technical problems, an object of the present invention is to provide a temperature sensor.

[0004] Another object of the present invention is to provide a heating device assembly having the above temperature sensor.

[0005] To achieve the above-mentioned objectives, an embodiment of the first aspect of the present invention provides a temperature sensor, comprising: a bracket, on which a support position is provided; a temperature sensing component, having a temperature sensing module, which is installed on the bracket and supported by the support position; a temperature sensing cap, which is covered on the bracket and assembled and connected to the bracket through an assembly structure, and the temperature sensing cap stops against the temperature sensing module to limit the temperature sensing module to the support position.

[0006] In the temperature sensor provided by the above embodiment of the present invention, the temperature sensing component is located on the bracket, and the temperature sensing cap is installed on the bracket while pressing the temperature sensing component to limit the position on the bracket, thereby realizing modular assembly and fixation of the temperature sensing cap, the bracket and the temperature sensing component, without the need to use limit springs, sleeves and other parts to achieve the limit fixation of the temperature sensing component and the bracket. The number of parts and components of the product is reduced, the number of installation steps is also reduced, and the assembly efficiency of the product is higher.

[0007] In addition, the temperature sensor in the above embodiment provided by the present invention may also have the following additional technical features:

[0008] In the above technical solution, the bracket is provided with a through hole, the support position includes a support step located around the through hole, the temperature sensing module is connected to the through hole, and the temperature sensing module is provided with a flange, and the flange rests on the support step.

[0009] In the present solution, a through hole is provided on the bracket, and the temperature sensing module is connected to the through hole, and its flange rests on the supporting step. The structure is simple and easy to assemble, and the interference between the supporting step and the flange can effectively limit the temperature sensing module to prevent the temperature sensing module from being pulled downward, thereby ensuring that the temperature sensing module is stably and reliably assembled in the assembled product. The structure can also effectively pre-fix the temperature sensing module on the bracket, so that the temperature sensing cap is not likely to cause the temperature sensing module to be displaced when it is installed on the bracket, and the product assembly accuracy is higher, and the yield rate is correspondingly higher.

[0010] In any of the above technical solutions, the temperature sensor further includes: an elastic buffer, and the elastic buffer is provided between the supporting position and the opposite surface of the temperature sensing module.

[0011] In this solution, an elastic buffer is provided between the support position and the relative surface of the temperature sensing module, which can buffer the impact between the bracket and the temperature sensing module, reduce the probability of impact damage to the temperature sensing module, and improve the durability of the product.

[0012] In any of the above technical solutions, the bracket is provided with a supporting portion located around the temperature sensing module, and the top wall cover of the temperature sensing cap is pressed on the supporting portion and stops against the temperature sensing module.

[0013] In the present solution, a supporting portion is provided on the bracket at the portion surrounding the temperature sensing cap, and when the top wall of the temperature sensing cap stops against the temperature sensing module to limit it in the supporting position, it is simultaneously pressed against the supporting portion of the bracket. In this way, on the one hand, the supporting area of ​​the top wall of the temperature sensing cap can be increased to prevent it from collapsing and deforming, and on the other hand, the impact of external force on the temperature sensing module can be shared, thereby achieving effective protection for the temperature sensing module.

[0014] Preferably, there is a spacing between the top support portion and the temperature sensing module, that is, a gap is formed between the side surface of the temperature sensing module and the top support portion. The gap can serve to insulate the temperature sensing module from the top support portion, reduce heat transfer from the temperature sensing module to the bracket, and allow more heat on the surface of the temperature sensing module to be transferred to the temperature-sensitive parts inside it, thereby improving the temperature measurement accuracy. At the same time, it can reduce the thermal impact of the bracket's heat storage on the temperature sensing module, thereby improving the temperature measurement sensitivity of the temperature sensing module.

[0015] In any of the above technical solutions, the bracket includes: a bracket body, the temperature sensing module is located on the bracket body; a base, the bracket body is located on the base, and the temperature sensing cap is installed on the bracket body and connected to the base through the assembly structure.

[0016] In the present solution, the bracket is formed into a component structure and specifically includes a bracket body and a base, so that the materials of the bracket body and the base can be selected respectively to take into account the temperature resistance and economy of the bracket. Specifically, the temperature sensing module is arranged on the bracket body, and the temperature sensing cap is installed on the bracket body and connected to the base through the assembly structure. When the product is working, since the temperature sensing cap will directly contact the temperature measuring component of the pot, the temperature is generally high. Correspondingly, the temperature of the bracket body covered by it is also correspondingly high. In comparison, the base that plays a connecting and fixing role is lower in temperature than the bracket body. In this way, the normal operation of the product is guaranteed. On the premise of reliable use, the structure of the bracket in the form of a component can enable the bracket body part of the bracket to select a material with slightly higher temperature resistance, while the base part can select a material with slightly lower temperature resistance, thereby reducing product costs and making the product more economical. Compared with the structure in which the base and the bracket body are constructed as the same component, the bracket is formed as a component structure of the bracket body and the base, and a heat transfer resistance between the components can be formed between the bracket body and the base. In this way, the external heat dissipation efficiency of the temperature sensing module through the bracket is reduced, so that the heat on the surface of the temperature sensing module can be transferred more to the temperature-sensitive parts inside it, thereby improving the temperature measurement accuracy.

[0017] In any of the above technical solutions, the bracket is provided with a connecting rod for installing the temperature sensor, wherein the connecting rod is provided with a lug protruding to the side of the connecting rod; and / or the temperature sensor also includes a spring, which abuts against the bracket and is used to elastically support the bracket so that the bracket can float along the extension and contraction direction of the spring.

[0018] In this solution, a connecting rod is arranged on the bracket. The connecting rod is used to engage with the corresponding mounting holes on the heating device or other equipment when the temperature sensor is assembled with the heating device or other equipment. A lug is provided on the connecting rod. The lug can be used to limit the connecting rod and even the temperature sensor when the connecting rod moves along the mounting hole until the lug abuts against the area around the mounting hole, thereby preventing the connecting rod from falling out of the mounting hole and ensuring reliable assembly of the temperature sensor.

[0019] More preferably, the connecting rod is a hollow cylindrical structure and communicates with the through hole on the bracket, and the lead wire of the temperature sensing component is led out from the inside of the connecting rod.

[0020] The temperature sensor also includes a spring. When the temperature sensor is assembled with a heating device or other equipment, the spring is pressed against the bracket and the heating device to realize the floating assembly of the temperature sensor on the heating device. In this way, the elastic force of the spring can be used to cause the component to be measured to maintain contact with the temperature sensing cap, thereby ensuring good contact between the temperature sensor and the component to be measured and improving the temperature measurement accuracy.

[0021] An embodiment of the second aspect of the present invention provides a heating device assembly, comprising: a heating device; and a temperature sensor as described in any of the above technical solutions, mounted on the heating device.

[0022] The heating device assembly provided in the above embodiment of the present invention has all the above beneficial effects by being provided with the temperature sensor described in any of the above technical solutions, which will not be described in detail here.

[0023] In the above technical solution, a mounting hole is provided on the heating device, and the connecting rod of the temperature sensor is connected to the mounting hole and can move along the mounting hole, wherein the lug of the connecting rod is located at the portion where the connecting rod passes out of the mounting hole, and the lug can abut against the portion around the mounting hole to limit the connecting rod from detaching from the mounting hole.

[0024] In this solution, the heating device is provided with a mounting hole and a connecting rod for connecting and assembling the temperature sensor, wherein the lug can be used to limit the connecting rod and even the temperature sensor when the connecting rod moves along the mounting hole until the lug abuts against the area around the mounting hole, thereby preventing the connecting rod from falling out of the mounting hole and ensuring reliable assembly of the temperature sensor.

[0025] In the above technical solution, an avoidance recess is provided on the hole wall of the mounting hole, and the avoidance recess is used to avoid the lug when it corresponds to the lug to facilitate the assembly and disassembly of the connecting rod and the mounting hole.

[0026] In the present scheme, an avoidance recess is provided at the hole wall of the mounting hole, so that when the connecting rod moves axially along the mounting hole with the lug corresponding to the avoidance recess, the avoidance recess avoids the lug to realize the connection rod being installed into or out of the mounting hole. This has the advantage of convenient loading and unloading of the connecting rod, and prevents damage to the mounting hole or the lug during loading and unloading of the connecting rod. After the connecting rod and the mounting hole are assembled, the connecting rod can be rotated to a position where the lug and the avoidance recess are misaligned, so that the lug can effectively limit the connecting rod. The structure is simple, and the assembly process between the temperature sensor and the heating device is convenient and quick, and does not require the use of limit springs, pins and other components. The product has fewer parts and the assembly steps are correspondingly reduced, which is more suitable for assembly line occasions.

[0027] In the above technical solution, a rotation limiting structure is provided between the temperature sensor and the heating device. The rotation limiting structure is used to form a limiting fit between the temperature sensor and the heating device to limit the rotation of the connecting rod when the connecting rod is passed through the mounting hole and rotated to a position where the lug is misaligned with the avoidance recess, so as to maintain the temperature sensor at a position where the lug is misaligned with the avoidance recess.

[0028] In the present embodiment, a rotation limiting structure is provided, and when the connecting rod is inserted into the mounting hole and rotated to a position where the lug is misaligned with the avoidance recess, a rotation limiting fit is formed between the temperature sensor and the heating device bracket through the rotation limiting structure to limit the rotation of the connecting rod, thereby maintaining the temperature sensor in the position where the lug is misaligned with the avoidance recess, thereby ensuring that the limiting effect of the lug is maintained reliably after the assembly is completed, thereby ensuring stable assembly of the temperature sensor and the heating device.

[0029] In any of the above technical solutions, the heating device is provided with a mounting hole penetrating from top to bottom, the connecting rod protrudes downward and penetrates the mounting hole, and the temperature sensor is located above the mounting hole to block the opening of the mounting hole.

[0030] In this solution, the mounting hole is in the form of a vertical penetration, so that the temperature sensor is located above the mounting hole to block the upward opening of the mounting hole. In this way, the temperature sensor can be used to block water from the mounting hole to prevent water from entering the mounting hole, which can help to waterproof the temperature sensing component inside the temperature sensor.

[0031] In the above technical solution, the heating device is provided with a stopper at a position below the mounting hole, and the stopper is used to abut against the connecting rod to limit the connecting rod from continuing to move downward when the connecting rod moves to a preset lowest position along the mounting hole.

[0032] In the present solution, a stopper is provided at a position below the mounting hole of the heating device for abutting against the connecting rod to limit the temperature sensor, which can protect the spring of the temperature sensor. At the same time, the lowest position of the temperature sensor is controlled to prevent problems such as poor temperature measurement caused by the temperature sensor being positioned too low.

[0033] In any of the above technical solutions, the heating device includes: a panel with a through hole provided thereon; a coil disk bracket located below the panel; and a base located below the coil disk bracket, wherein the temperature sensor is mounted on the coil disk bracket or on the base, and the top of the temperature sensor protrudes to the outside of the panel along the through hole.

[0034] In this solution, the temperature sensor is installed on the coil disk bracket or base and is extended to the outside of the panel through the through hole on the panel. This allows the temperature sensor to contact the temperature measuring component of the pot outside the panel for temperature measurement, which helps to improve the accuracy of temperature measurement.

[0035] In the above technical solution, the coil disk bracket is provided with a groove opposite to the through hole, and the heating device assembly also includes: a sealing ring, having a sealing portion located between the panel and the coil disk bracket and sealingly connecting the panel and the coil disk bracket, and a water retaining ring connected to the sealing portion and protruding downward into the groove, and the temperature sensor is nested in the water retaining ring.

[0036] In the present solution, a sealing ring is provided, and its sealing portion seals and connects the panel and the coil disk bracket, and a water retaining ring is provided on the sealing portion and protrudes downward into the groove of the coil disk bracket. In this way, the gap between the coil disk bracket and the panel can be reliably sealed, and water entering through the through hole is prevented from spreading along the gap between the coil disk bracket and the panel to the coil winding part of the coil disk bracket, thereby improving the electrical safety of the product.

[0037] In the above technical solution, an adhesive layer is provided between the sealing portion and the panel; and / or an adhesive layer is provided between the sealing portion and the coil disk support; and / or the panel and the coil disk support clamp the sealing portion.

[0038] In the present scheme, an adhesive layer is provided between the sealing part and the panel, which can further improve the tightness of the sealing fit between the sealing part and the panel, prevent water from spreading to the coil winding part along the gap between the sealing part and the panel, and improve the electrical safety of the product. The sealing part and the panel are bonded by the adhesive layer, which can also play a role in positioning the sealing ring and the panel, improve the assembly accuracy of the sealing ring, and improve the waterproof performance; an adhesive layer is provided between the sealing part and the coil disk bracket, which can further improve the tightness of the sealing fit between the sealing part and the coil disk bracket, prevent water from spreading to the coil winding part along the gap between the sealing part and the coil disk bracket, and improve the electrical safety of the product. The sealing part and the coil disk bracket are bonded by the adhesive layer, which can also play a role in positioning the sealing ring and the coil disk bracket, and improve the waterproof performance; the panel and the coil disk bracket are provided to clamp the sealing part, so as to achieve a close fit between the sealing part and the panel and the coil disk bracket by squeezing the sealing part, prevent water from spreading to the coil winding part along the gap between the sealing part and the panel or the coil disk bracket, and improve the electrical safety of the product.

[0039] In the above technical solution, the outer diameter of the water retaining ring is larger than the inner diameter of the groove; and / or the position of the temperature sensor in the groove is constructed with a rib, and the width of the temperature sensor at the rib is consistent with the width of the groove.

[0040] In the present scheme, the outer diameter of the water retaining ring is set to be larger than the inner diameter of the groove, so that the part of the water retaining ring extending into the groove forms an interference fit with the groove, which can achieve the gap between the inner wall of the groove and the outer surface of the water retaining ring to seal, thereby preventing water from entering the coil winding part of the coil disk bracket through the gap between the inner wall of the groove and the outer surface of the water retaining ring, thereby improving the electrical safety of the product; a convex rib is provided at the part where the temperature sensor is located in the groove, so as to reduce the radial shaking of the temperature sensor in the groove, so that the sensor assembly is more stable.

[0041] In the above technical solution, the heating device is provided with a drainage structure, which is communicated with the groove and is used to guide the liquid in the groove to the outside of the heating device.

[0042] In this solution, a drainage structure is provided to drain the water in the groove to the outside of the heating device, so that the water in the groove can be drained in time, avoiding hygiene problems and electrical safety hazards caused by liquid accumulation in the groove.

[0043] Optionally, the heating appliance assembly is an induction cooker, a stove, an electric rice cooker, an electric pressure cooker, etc.

DETAILED DESCRIPTION

[0059] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0060] 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0061] Refer to the following Figures 2 to 9 A temperature sensor and a heating device assembly according to some embodiments of the present invention are described.

[0062] like Figure 2 and Figure 3As shown, the temperature sensor 100 provided by the embodiment of the first aspect of the present invention includes: a bracket 110 , a temperature sensing member 120 and a temperature sensing cap 130 .

[0063] Specifically, a support position 1121 is provided on the bracket 110; the temperature sensing component 120 has a temperature sensing module 122, the temperature sensing module 122 is installed on the bracket 110 and supported by the support position 1121; the temperature sensing cap 130 is covered on the bracket 110 and assembled and connected with the bracket 110 through an assembly structure, and the temperature sensing cap 130 stops against the temperature sensing module 122, limiting the temperature sensing module 122 on the support position 1121.

[0064] In the temperature sensor 100 provided by the above embodiment of the present invention, the temperature sensing element 120 is located on the bracket 110, and the temperature sensing cap 130 can be connected to the bracket 110 component through an assembly structure, so that the temperature sensing cap 130 can be used to fix and limit the temperature sensing element 120, so that the temperature sensing cap 130 is covered on the bracket 110 and the temperature sensing element 120 is pressed and limited on the bracket 110, thereby realizing modular assembly and fixation of the temperature sensing cap 130, the bracket 110 and the temperature sensing element 120, without the need to use limit springs, sleeves and other parts to realize the limit fixation of the temperature sensing element 120 and the bracket 110, the number of parts of the product is reduced, the installation steps are also reduced, and the assembly efficiency of the product is higher.

[0065] More specifically, if Figure 1 As shown, in the prior art, the temperature sensing cap of the temperature sensor is integrally connected with the plastic shell through insert injection molding to form a shell 20'. The temperature sensing component 10' is installed into the shell 20' from bottom to top, and the temperature sensing module of the temperature sensing component 10' is pressed against the inner wall of the shell 20' through the sleeve 40'. Finally, the sleeve 40' and the temperature sensing component 10' are limited by the limit spring 30'. The structure has a large number of parts and many assembly steps. It can be understood that the temperature sensing component 10' is basically connected to its temperature sensing module with a lead wire. The structure of limiting the position by the limit spring 30' will bring the risk of the limit spring 30' touching the lead wire, which poses a safety hazard. In the present solution, the temperature sensing module 122 is mounted on the bracket 110 and supported by the support position 1121 of the bracket 110. The temperature sensing cap 130 is covered on the bracket 110 to press and limit the temperature sensing module 122. The dimension chain for limiting the temperature sensing module 122 is shorter, the assembly is simpler and more convenient, and the assembly accuracy is higher. When the temperature sensing cap 130, the bracket 110 and the temperature sensing element 120 are assembled and fixed, there is no need to use the limiting spring 30', the sleeve 40' and other components for limiting. This not only simplifies the number of parts of the product, reduces the assembly steps and increases the assembly efficiency, but also avoids the risk of touch breakdown, making the product safer and more reliable.

[0066] In one embodiment of the present invention, Figure 2 and Figure 3As shown, the assembly structure includes a protrusion 134 and a slot 1141, wherein one of the temperature sensing cap 130 and the bracket 110 is provided with a protrusion 134, and the other is provided with a slot 1141. After the temperature sensing cap 130 is covered on the bracket 110, the protrusion 134 is snapped into the slot 1141 to realize the assembly and fixation between the temperature sensing cap 130 and the bracket 110, which can ensure that the temperature sensing cap 130 is reliably pressed and fixed to the temperature sensing module 122, and has the advantage of easy assembly.

[0067] In one embodiment of the present invention, the assembly structure is a threaded connection structure, specifically including internal threads and external threads that can be screwed together, wherein one of the temperature sensing cap 130 and the bracket 110 is provided with an internal thread, and the other is provided with an external thread. After the temperature sensing cap 130 is covered on the bracket 110, it can be screwed together and fixed with the bracket 110 thread, which can ensure that the temperature sensing cap 130 is reliably pressed and fixed to the temperature sensing module 122, and has the advantage of easy assembly.

[0068] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the bracket 110 is provided with a through hole 1122, and the support position 1121 includes a supporting step located around the through hole 1122, the temperature sensing module 122 is connected to the through hole 1122, and the temperature sensing module 122 is provided with a flange 1222, and the flange 1222 rests on the supporting step, wherein the interference between the supporting step and the flange 1222 can effectively limit the temperature sensing module 122, prevent the temperature sensing module 122 from being pulled downward, and ensure that the temperature sensing module 122 in the assembled product is stably and reliably assembled, and the bracket 110 structure can also realize effective pre-fixation of the temperature sensing module 122 on the bracket 110, so that it is not easy to cause the temperature sensing module 122 to be offset when the temperature sensing cap 130 is installed on the bracket 110, the product assembly accuracy is higher, and the yield rate is correspondingly higher.

[0069] In addition, this structure can realize the assembly of the temperature sensor 100 components from top to bottom, which is more convenient and has higher assembly accuracy. Specifically, in this structure, the temperature sensing element 120 is passed downward through the through hole 1122 from the end of the lead wire 124 thereof until the flange 1222 of the temperature sensing module 122 rests on the supporting step, so that the temperature sensing module 122 and the bracket 110 are assembled. Thereafter, the temperature sensing cap 130 is downwardly covered on the bracket 110 and the temperature sensing cap 130 and the bracket 110 are assembled and connected through the assembly structure to complete the whole structure. The packaging of the temperature sensor 100 has few assembly steps and high assembly efficiency. In the entire assembly structure, the functional components (bracket 110 and temperature sensing cap 130) for limiting the temperature sensing module 122 are basically directly matched with the temperature sensing module 122, with a short dimensional chain, higher assembly accuracy, and more convenient assembly operation. Compared with the existing structure that requires the temperature sensing component to be extended into the shell for blind installation, the temperature sensing cap 130 is finally used for packaging in this solution, and before packaging, it is an open external assembly from top to bottom, which can be more conducive to improving the assembly accuracy of the product.

[0070] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the temperature sensor 100 also includes an elastic buffer 140, and an elastic buffer 140 is provided between the supporting position 1121 and the relative surface of the temperature sensing module 122, so that the elastic buffer 140 can provide buffering between the two, thereby reducing the impact between the bracket 110 and the temperature sensing module 122, reducing the probability of impact damage to the temperature sensing module 122, and improving the durability of the product.

[0071] Optionally, the elastic buffer 140 is a rubber piece, a silicone piece, a buffer cotton or other elastic material piece.

[0072] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the bracket 110 is provided with a top supporting portion 1123 located around the temperature sensing module 122, and the top wall 132 of the temperature sensing cap 130 is pressed on the top supporting portion 1123 and stops against the temperature sensing module 122. Among them, by setting the top wall 132 of the temperature sensing cap 130 to stop against the temperature sensing module 122 to limit it to the support position 1121, it is also pressed on the top supporting portion 1123 of the bracket 110. In this way, on the one hand, the support area of ​​the top wall 132 of the temperature sensing cap 130 can be increased to prevent it from collapsing and deforming, and on the other hand, the impact of external force on the temperature sensing module 122 can be shared, so that the temperature sensing module 122 can be effectively protected.

[0073] Preferably, if Figure 2As shown, there is a gap between the top support portion 1123 and the temperature sensing module 122. In other words, a gap is formed between the side surface of the temperature sensing module 122 and the top support portion 1123. The gap can play a role in thermal insulation between the temperature sensing module 122 and the top support portion 1123, thereby reducing heat transfer from the temperature sensing module 122 to the bracket 110, allowing more heat on the surface of the temperature sensing module 122 to be transferred to the temperature sensitive component 1223 inside it, thereby improving the temperature measurement accuracy. At the same time, the thermal influence of the heat storage of the bracket 110 on the temperature sensing module 122 can be reduced, thereby improving the temperature measurement sensitivity of the temperature sensing module 122.

[0074] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the bracket 110 includes: a bracket body 112 and a base 114, the temperature sensing module 122 is located on the bracket body 112; the bracket body 112 is located on the base 114, and the temperature sensing cap 130 is covered on the bracket body 112 and connected to the base 114 through an assembly structure.

[0075] More specifically, if Figure 2 As shown, a through groove is provided on the base 114, and the bracket body 112 is connected to the through groove, wherein the bracket body 112 is provided with a radially extending extension edge, the top surface of the extension edge is higher than the supporting step and serves as a supporting portion 1123 to rest on the temperature sensing cap 130, and the bottom surface of the extension edge rests on the base 114. When the temperature sensing cap 130 is connected to the base 114, the extension edge of the bracket body 112 is limited between the temperature sensing cap 130 and the base 114, and the temperature sensing module 122 is limited between the supporting step and the temperature sensing cap 130.

[0076] In the present solution, the bracket 110 is formed into a component structure and specifically includes a bracket body 112 and a base 114, so that the materials of the bracket body 112 and the base 114 can be selected respectively to take into account the temperature resistance and economy of the bracket 110. Specifically, the temperature sensing module 122 is arranged on the bracket body 112, and the temperature sensing cap 130 is covered on the bracket body 112 and connected to the base 114 through the assembly structure. When the product is working, since the temperature sensing cap 130 will directly contact the temperature measuring component of the pot, the temperature is generally high. Correspondingly, the temperature of the bracket body 112 covered by it is also correspondingly high. In comparison, the base 114, which plays a connecting and fixing role, has a lower temperature than the bracket body 112. In this way, the product is guaranteed Under the premise of reliable normal use, the bracket 110 is a component-type structure, which allows the bracket body 112 of the bracket 110 to use a material with slightly higher temperature resistance, while the base 114 can use a material with slightly lower temperature resistance, thereby reducing product costs and making the product more economical. Compared with the structure in which the base 114 and the bracket body 112 are constructed as the same component, the bracket 110 is formed as a component-type structure of the bracket body 112 and the base 114, and a heat transfer resistance between the components can be formed between the bracket body 112 and the base 114. In this way, the external heat dissipation efficiency of the temperature sensing module 122 through the bracket 110 is reduced, so that the heat on the surface of the temperature sensing module 122 can be transferred more to the temperature-sensitive parts inside it, thereby improving the temperature measurement accuracy.

[0077] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the bracket 110 is provided with a connecting rod 1124 for installing the temperature sensor 100, wherein the connecting rod 1124 is provided with a lug 1125 protruding to the side of the connecting rod 1124. More preferably, the connecting rod 1124 is a hollow cylindrical structure and communicates with the through hole 1122 on the bracket 110, and the lead wire 124 of the temperature sensing element 120 is led out from the inside of the connecting rod 1124.

[0078] In the present embodiment, a connecting rod 1124 is provided on the bracket 110. The connecting rod 1124 is used to engage with the corresponding mounting holes 222 on the heating device 200 and other equipment when the temperature sensor 100 is assembled with the heating device 200 and other equipment. A lug 1125 is provided on the connecting rod 1124. The lug 1125 can be used to limit the connecting rod 1124 and even the temperature sensor 100 when the connecting rod 1124 moves along the mounting hole 222 until the lug 1125 abuts against the area around the mounting hole 222, thereby preventing the connecting rod 1124 from slipping out of the mounting hole 222 and ensuring that the temperature sensor 100 is assembled reliably.

[0079] In one embodiment of the present invention, Figure 2 and Figure 3As shown, the temperature sensor 100 also includes a spring 150, which rests on the bracket 110 and is used to elastically support the bracket 110 so that the bracket 110 can float along the expansion and contraction direction of the spring 150. In this way, the elastic force of the spring 150 can be used to cause the temperature-measured component to maintain abutment with the temperature-sensing cap 130, thereby ensuring that the temperature sensor 100 is in good contact with the temperature-measured component and improving the temperature measurement accuracy.

[0080] In a preferred embodiment of the present invention, the temperature sensing cap 130 is a heat conducting member. Specifically, the temperature sensing cap 130 is preferably a component whose material has a temperature resistance value greater than or equal to 500°C. More preferably, the temperature sensing cap 130 is a component whose material has a temperature resistance value of 800°C to 1000°C, such as a metal cap such as an aluminum alloy cap, a stainless steel cap, or a ceramic cap. The temperature sensing cap 130 is in direct contact with the heat source (the theoretical distance value is 0). For example, in a normal dry-burning scene of an induction cooker, it has been measured that before program protection, the temperature of the heat source at the bottom of the pot can reach 450°C to 500°C. This design makes the temperature sensing cap 130 a component whose material has a temperature resistance value greater than or equal to 500°C, ensuring that it will not deform at high temperatures.

[0081] Of course, the temperature sensing cap 130 is not limited to a structure in which the whole is a heat-conducting part. According to needs, the temperature sensing cap can also be designed to include a plastic part and a heat-conducting (such as metal or ceramic) part. The plastic part constructs the annular wall of the temperature sensing cap, and the heat-conducting part is connected to the plastic part and sealed at one axial end of the plastic part for heat conduction between the temperature sensing module and the component to be measured.

[0082] In a preferred embodiment of the present invention, the bracket body 112 is a component whose material has a temperature resistance value greater than or equal to 300°C. More preferably, the bracket body 112 is a component whose material has a temperature resistance value of 300°C to 350°C, such as a heat-resistant plastic. The distance between the bracket body 112 and the heat source is 1 mm, and the temperature of the heated field is measured to be 250°C to 300°C. The temperature resistance value of the material is controlled to be 300°C to 350°C, ensuring that the bracket body 112 will not deform at high temperatures.

[0083] In a preferred embodiment of the present invention, Figure 2 As shown, the temperature sensing module 122 includes a shell 1221, a temperature-sensitive component 1223 and a packaging material 1224. The temperature-sensitive component 1223 is located in the shell 1221. The packaging material 1224 is located in the shell 1221 and packages and fixes the temperature-sensitive component 1223. The shell 1221 is an insulating component, and the temperature resistance of its material is greater than or equal to 500°C. More preferably, the shell 1221 is an insulating component with a temperature resistance of 800°C to 1000°C, such as insulating thermal conductive materials such as ceramics.

[0084] In a preferred embodiment of the present invention, the elastic buffer 140 is a component whose material has a temperature resistance value greater than or equal to 180°C, such as PET (polyethylene terephthalate), PA66 (nylon-66) or other modified temperature-resistant materials that meet the requirements. Among them, since the elastic buffer 140 is located in the space defined by the temperature sensing cap 130 and the bracket 110, and there is no direct contact between it and the temperature sensing cap 130, it has been measured that the temperature of the space defined by the temperature sensing cap 130 and the bracket 110 in the dry burning scene is between 150°C and 180°C. In this design, the elastic buffer 140 is set as a component whose material has a temperature resistance value greater than or equal to 180°C to ensure that it will not deform at high temperatures.

[0085] like Figures 4 to 9 As shown, the heating device assembly provided by the embodiment of the second aspect of the present invention includes: a heating device 200 and the temperature sensor 100 described in any one of the above embodiments, and the temperature sensor 100 is installed on the heating device 200.

[0086] The heating device assembly provided in the above embodiment of the present invention has all the above beneficial effects by being provided with the temperature sensor 100 described in any of the above technical solutions, which will not be described in detail here.

[0087] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, a mounting hole 222 is provided on the heating device 200, and a connecting rod 1124 of the temperature sensor 100 is connected to the mounting hole 222 and can move along the mounting hole 222, wherein a lug 1125 of the connecting rod 1124 is located at a portion where the connecting rod 1124 passes out of the mounting hole 222, and the lug 1125 can abut against a portion around the mounting hole 222 to limit the connecting rod 1124 from being separated from the mounting hole 222.

[0088] In one embodiment of the present invention, Figure 5 and Figure 6As shown, an avoidance recess is provided at the hole wall of the mounting hole 222 , and the avoidance recess is used to avoid the lug 1125 when it corresponds to the lug 1125 so as to facilitate the connection rod 1124 to be assembled and unassembled from the mounting hole 222 . Among them, when the connecting rod 1124 moves axially along the mounting hole 222 with the lug 1125 corresponding to the avoidance recess, the avoidance recess avoids the lug 1125 to realize the connection rod 1124 to be installed in or out of the mounting hole 222. This has the advantage of convenient loading and unloading of the connecting rod 1124, and prevents damage to the mounting hole 222 or the lug 1125 during loading and unloading of the connecting rod 1124. After the connecting rod 1124 and the mounting hole 222 are assembled, the connecting rod 1124 can be rotated to a position where the lug 1125 is misaligned with the avoidance recess, so that the lug 1125 can effectively limit the connection rod 1124. The structure is simple, and the assembly process between the temperature sensor 100 and the heating device 200 is convenient and quick, and does not require the use of limit springs, pins and other components. The product has fewer parts and the assembly steps are correspondingly reduced, which is more suitable for assembly line occasions.

[0089] More specifically, if Figure 8 and Fig. 9 As shown, two lugs 1125 are provided on the connecting rod 1124, and the mounting hole 222 is a rectangular hole. The outer diameter of the connecting rod 1124 is suitable for the width of the short side of the rectangular hole, and the part where the long side of the rectangular hole is wider than the short side is used as an avoidance recess. Of course, this solution is not limited to this, and those skilled in the art can also select the mounting hole 222 according to needs, such as an elliptical hole, a triangular hole, etc.

[0090] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, a rotation limiting structure is provided between the temperature sensor 100 and the heating device 200. The rotation limiting structure is used to form a limiting fit between the temperature sensor 100 and the heating device 200 to limit the rotation of the connecting rod 1124 when the connecting rod 1124 is connected to the mounting hole 222 and rotated to a position where the lug 1125 is misaligned with the avoidance recess, so as to maintain the temperature sensor 100 at a position where the lug 1125 is misaligned with the avoidance recess. In this way, it can be ensured that the limiting effect of the lug 1125 is maintained reliably after the assembly is completed, thereby ensuring that the temperature sensor 100 and the heating device 200 are stably assembled.

[0091] Specifically, the rotation limiting structure includes a guide portion 262 and a limiting groove 264. The guide portion 262 extends into the limiting groove 264. When the connecting rod 1124 moves along the mounting hole 222, the guide portion 262 can slide along the limiting groove 264. When the connecting rod 1124 rotates in the mounting hole 222, the groove wall of the limiting groove 264 abuts against the guide portion 262 to limit the rotation of the connecting rod 1124. Preferably, as Figure 7As shown, the heating device 200 is provided with a limiting groove 264 at a position below the mounting hole 222 , and the temperature sensor 100 uses its lug 1125 as a guide portion 262 , so that the lug 1125 cooperates with the limiting groove 264 to limit the rotation of the connecting rod 1124 .

[0092] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, the heating device 200 is provided with a mounting hole 222 which passes through from top to bottom, the connecting rod 1124 protrudes downward and is connected to the mounting hole 222, and the temperature sensor 100 is located above the mounting hole 222 to block the opening of the mounting hole 222. In this way, the temperature sensor 100 can be used to block water from the mounting hole 222 to prevent water from entering the mounting hole 222, which can help to waterproof the temperature sensing component 120 inside the temperature sensor 100.

[0093] Furthermore, if Figure 6 As shown, the heating device 200 is provided with a stopper 232 at a position below the mounting hole 222. The stopper 232 is used to abut against the connecting rod 1124 to limit the connecting rod 1124 from continuing to move downward when the connecting rod 1124 moves to a preset lowest position along the mounting hole 222. This can protect the spring 150 of the temperature sensor 100. At the same time, it can control the lowest position of the temperature sensor 100 to prevent problems such as poor temperature measurement caused by the temperature sensor 100 being positioned too low.

[0094] In one embodiment of the present invention, Figure 4 , Figure 5 and Figure 6 As shown, the heating device 200 includes: a panel 210, a coil disk bracket 220 and a base 230, the panel 210 is provided with a through hole 212; the coil disk bracket 220 is located below the panel 210; the base 230 is located below the coil disk bracket 220, the temperature sensor 100 is installed on the coil disk bracket 220 or on the base 230, and the top of the temperature sensor 100 protrudes to the outside of the panel 210 along the through hole 212, so that the temperature sensor 100 and the temperature measuring component of the pot outside the panel 210 can contact and measure the temperature, which is conducive to improving the accuracy of temperature measurement.

[0095] In one embodiment of the present invention, Figure 4 , Figure 5 and Figure 6As shown, the coil disk support 220 is provided with a groove 224 opposite to the through hole 212, and the heating device assembly further includes a sealing ring 240, the sealing ring 240 has a sealing portion 242 and a water retaining ring 246, the sealing portion 242 is located between the panel 210 and the coil disk support 220 and seals and connects the panel 210 and the coil disk support 220, the water retaining ring 246 is connected to the sealing portion 242 and protrudes downward into the groove 224, and the temperature sensor 100 is nested in the water retaining ring 246. This structure can achieve reliable sealing of the gap between the coil disk support 220 and the panel 210, prevent water entering along the through hole 212 from expanding along the gap between the coil disk support 220 and the panel 210 to the coil winding part of the coil disk support 220, and improve the electrical safety of the product.

[0096] In a preferred embodiment of the present invention, the sealing ring 240 is a component whose material has a temperature resistance value greater than or equal to 200°C to 250°C. In this structure, the sealing ring 240 is preferably completely below the panel 210 and is not exposed at the through hole 212. Since the sealing ring 240 is not directly radiated by the heat source, its heat is transferred through the panel 210. According to measurement, in the dry burning scenario, the temperature of this area is 180°C to 200°C. In this design, the sealing ring 240 is set to be a component whose material has a temperature resistance value greater than or equal to 200°C to 250°C to ensure that it will not deform at high temperatures to ensure the sealing effect.

[0097] Of course, in the case where the sealing ring 240 is partially exposed at the through hole 212, the sealing ring 240 needs to be designed to be a component with a temperature resistance value greater than or equal to 300℃~350℃. Among them, since the exposed part of the sealing ring 240 is directly exposed to the heat radiation from the heat source, it has been measured that the temperature of the exposed part of the sealing ring 240 is 250℃~300℃ within a range of 1mm from the heat source. The sealing ring 240 needs to be designed to be a component with a temperature resistance value greater than or equal to 300℃~350℃ to ensure its sealing reliability at high temperatures.

[0098] Preferably, an adhesive layer 250 is provided between the sealing portion 242 and the panel 210. Specifically, a glue groove is provided on the upper surface of the sealing portion 242, and an adhesive material is provided in the glue groove. The adhesive material solidifies to form an adhesive layer 250 that bonds the sealing portion 242 and the panel 210. Of course, the present solution is not limited thereto. According to requirements, it is also possible to design that an adhesive layer is provided between the sealing portion 242 and the coil disk bracket 220, and / or the panel 210 and the coil disk bracket 220 clamp the sealing portion 242.

[0099] Preferably, the outer diameter of the water retaining ring 246 is larger than the inner diameter of the groove 224. In this way, the portion of the water retaining ring 246 extending into the groove 224 forms an interference fit with the groove 224, which can seal the gap between the inner wall of the groove 224 and the outer surface of the water retaining ring 246, thereby preventing water from entering the coil winding portion of the coil disk bracket 220 through the gap between the inner wall of the groove 224 and the outer surface of the water retaining ring 246, thereby improving the electrical safety of the product.

[0100] In one embodiment of the present invention, Figure 6 As shown, the portion of the temperature sensor 100 located in the groove 224 is constructed with a rib 1142, and the width of the temperature sensor 100 at the rib 1142 is consistent with the width of the groove 224, so that the radial shaking of the temperature sensor 100 in the groove 224 can be reduced, making the assembly of the temperature sensor 100 more stable.

[0101] In one embodiment of the present invention, the heating device 200 is provided with a drainage structure, which is communicated with the groove 224 and is used to guide the liquid in the groove 224 to the outside of the heating device 200, so that the water in the groove 224 can be discharged in time, avoiding hygiene problems and electrical safety hazards caused by liquid accumulation in the groove 224.

[0102] More specifically, if Figure 6 and Fig. 9 As shown, the drainage structure includes a drainage hole 2241 provided on the groove 224 for draining the groove 224, and a water outlet 236 provided on the base 230, wherein the water discharged through the drainage hole 2241 reaches the base 230 and can be discharged outside the base 230 along the water outlet 236. Preferably, as Figure 6 As shown, a water retaining rib 234 is provided on the base 230, and a water outlet 236 is provided at a position of the base 230 corresponding to the area enclosed by the water retaining rib 234, wherein a drainage hole 2241 is located above the area enclosed by the water retaining rib 234, and water discharged from the drainage hole 2241 is discharged into the area enclosed by the water retaining rib 234, and will not flow to a position of the base 230 located outside the water retaining rib 234, thereby avoiding affecting components in the base 230.

[0103] Optionally, the heating appliance assembly is an induction cooker, a stove, an electric rice cooker, an electric pressure cooker, etc.

[0106] The temperature sensing component 120 includes a lead wire 124 and a temperature sensing module 122. The temperature sensing module 122 is preferably a thermistor module, which specifically includes a shell 1221, a temperature-sensitive component 1223 and a packaging material 1224. The shell 1221 is preferably a ceramic sleeve. The shell 1221 is provided with a flange 1222. The temperature-sensitive component 1223 is located in the shell 1221. The packaging material 1224 is located in the shell 1221 and packages and fixes the temperature-sensitive component 1223. The temperature-sensitive component 1223 can be specifically a thermistor, and the temperature-sensitive component 1223 is electrically connected to the lead wire 124.

[0107] The bracket 110 includes a bracket body 112 and a base 114. The center of the bracket body 112 is a through hole 1122, and a supporting step is constructed around the through hole 1122, wherein an extension edge extending outward from the outer edge of the supporting step is provided on the bracket body 112, and the top of the extension edge is a circular ring structure, and the lower surface of the extension edge contacts the top of the base 114. The flange 1222 of the shell 1221 of the temperature sensing module 122 rests on the supporting step, and an elastic buffer 140 is provided between the flange 1222 and the supporting step. The elastic buffer 140 plays a role in buffering the force between the temperature sensing module 122 and the bracket body 112.

[0108] The temperature sensing cap 130 is a metal cap, which is mounted on the bracket body 112. Three convex buckles 134 are evenly distributed on the outer edge of the temperature sensing cap 130. The convex buckles 134 are squeezed into the card slots 1141 of the base 114 to complete the packaging of the entire temperature sensor 100. There are four convex ribs 1142 on the outside of the base 114. The outer diameter of the base 114 at the convex ribs 1142 is smaller than the inner diameter of the groove 224 of the coil disk bracket 220. The convex ribs 1142 play a role in limiting the radial shaking of the temperature sensor 100. Of course, the number of convex buckles 134 is not limited to 3. Those skilled in the art can adjust the number of convex buckles 134 to 1, 2, 4, 5, etc. according to needs. The number of convex ribs 1142 is not limited to 4. Those skilled in the art can adjust the number of convex ribs 1142 to 2, 3, 5, etc. according to needs.

[0109] Specific embodiment 2 (such as Figures 4 to 9 (shown)

[0110] The heating device assembly is an induction cooker, including a heating device 200 and the temperature sensor 100 in the first specific embodiment.

[0111] The heating device 200 includes a panel 210, a coil disk bracket 220 and a base 230. The temperature sensor 100 is installed on the coil disk bracket 220, and the coil disk bracket 220 is installed on the base 230. The panel 210 is preferably a microcrystalline board. The panel 210 is located above the coil disk bracket 220, and a through hole 212 is provided on the panel 210. The temperature sensor 100 passes through the through hole 212 upward and protrudes to the outside of the panel 210, wherein the portion of the temperature sensor 100 located in the through hole 212 is clearance-matched with the through hole 212.

[0112] A sealing ring 240 is provided between the panel 210 and the coil disk bracket 220. A glue groove is provided on the upper side of the sealing ring 240. Solid glue is placed in the groove to stick the sealing ring 240 to the panel 210. Of course, the sealing ring 240 can also be designed to be stuck to the coil disk bracket 220, wherein the inner circle of the sealing ring 240 has a downwardly extending water retaining ring 246. The outer diameter of the water retaining ring 246 is larger than the inner diameter of the groove 224 on the coil disk bracket 220, and the water retaining ring 246 protrudes downward into the groove 224. The water retaining ring 246 can be used to prevent liquid entering the through hole 212 of the panel 210 from entering the coil winding part of the coil disk bracket 220.

[0113] A mounting hole 222 is provided on the coil disk bracket 220, and a limiting rib is provided at a position below the mounting hole 222 of the coil disk bracket 220, and the limiting rib defines a limiting groove 264.

[0115] The base 114 of the temperature sensor 100 blocks the upper opening of the mounting hole 222 on the upper side. When liquid flows in from the gap between the panel 210 and the temperature sensor 100, the water cannot fall directly into the mounting hole 222 due to the obstruction of the temperature sensor 100, but falls into the groove 224 of the coil disk bracket 220 located on the outside of the mounting hole 222.

The number of parts and components of the product is reduced, the installation steps are also reduced, and the assembly efficiency of the product is higher.
