Description

Technical Field

[0001] This utility model relates to the field of kettle technology, and in particular to a heating plate mounting structure for a kettle. Background Technology

[0002] Electric kettles are a common household appliance. Existing kettles are usually made of stainless steel or glass, and the heating element is embedded in the glass kettle to achieve the effect of heating and keeping the water warm. For example, utility model patent CN202023348593.0 discloses a base structure and a health-preserving kettle. The base structure is used for the installation of the kettle body and heating plate. The heating plate is set on the base. The bottom of the kettle body narrows to form a support part. The edge of the heating plate extends downward to form a retaining edge. The heating plate abuts against the support part using the retaining edge to form a receiving cavity. Silicone is injected into the receiving cavity. The base includes a base and an annular bracket set above the base. The annular bracket is hollow in the middle, and the support part is interference-fitted and placed below the receiving cavity. The thermoplasticity of the silicone allows it to be integrated into the receiving cavity, which can maintain the seal between them. It can be used without waiting for the silicone to solidify for a long time. The annular bracket above the base can catch excess silicone injected, preventing it from flowing into the base and avoiding damage to other devices set in the base. This patent installs the heating plate inside the glass kettle by embedding it, which cannot avoid the water in the kettle coming into direct contact with the metal heating plate, resulting in heavy metal pollution. In addition, the installation method between the coupler, the heating plate, and the base is cumbersome and not conducive to rapid production and installation. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heating plate mounting structure for a kettle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A heating plate mounting structure for a kettle includes a kettle body, a kettle body base, and a power base. The kettle body base is located below the kettle body and is electrically connected to the power base to heat the kettle body. The lower part of the kettle body has a groove. The kettle body base includes an outer shell, a heating plate, a high-temperature resistant coupler, and a clamp. The heating plate is detachably installed to the outer shell via the high-temperature resistant coupler, and the top surface of the heating plate is opposite to the bottom surface of the kettle body. The clamp is wrapped in the groove and fitted to the outer shell, so that the heating plate is tightly attached to the bottom surface of the kettle body.

[0006] Furthermore, the clamp has a first mounting ear at its front end and a second mounting ear at its rear end. The screw passes through the first and second mounting ears to fasten and fix the clamp. The first mounting ear has an inclined surface that is adapted to the screw head.

[0007] Furthermore, the clamp is provided with an elastic element, which is connected to the clamp at both ends.

[0008] Furthermore, the elastic element has gaskets extending outward on both sides, and the inner wall of the clamp has gasket grooves corresponding to the positions of the gaskets, with the gaskets being fitted and installed in the gasket grooves.

[0009] Furthermore, the clamp is L-shaped, with a clamping edge and an outward flange. The clamping edge is adapted to the shape of the groove and is set close to the inner wall of the groove. The outward flange folds outward from the top of the clamping edge and abuts against the top of the groove.

[0010] Furthermore, the clamp is Z-shaped and has a clamping edge, an outward folded edge, and an inward folded edge. The clamping edge is adapted to the shape of the groove and is set close to the inner wall of the groove. The outward folded edge folds outward from the top of the clamping edge and abuts against the top of the groove. The inward folded edge folds inward from the bottom of the clamping edge and fits against the bottom surface of the heating plate, so that the heating plate is close to the bottom of the kettle body.

[0011] Furthermore, the outer casing is provided with a first connecting post, and the clamp is provided with a clamp connecting post corresponding to the position of the first connecting post. The first connecting post and the clamp connecting post abut against each other and are fixed together by screws.

[0012] Furthermore, a connecting strap is provided between the kettle body and the outer shell, and a slot is provided at the bottom of the connecting strap. The top of the outer shell is adapted to be installed in the slot. The inner edge of the connecting strap is adapted to the shape of the outer edge of the kettle body to form an inner / outer and upper / lower fastening structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] Example 1:

[0040] like Figures 1-5 As shown, a heating element mounting structure for a kettle includes a kettle body 1, a kettle body base 2, and a power base 3. The kettle body base 2 is fixed to the bottom of the kettle body 1. The kettle body 1 and the power base 3 are detachable and compatible. The kettle body base 2 and the power base 3 are electrically connected to heat the kettle body 1. Specifically, the kettle body 1 is an all-glass structure with a flat bottom surface and includes a handle, lid, and spout. The kettle body base 2 has a heating structure fixed to the bottom of the kettle body 1 to heat or keep the liquid inside the kettle body 1 warm. The power base 3 is electrically connected to a power source and coupled to the kettle body base 2.

[0041] like Figure 2As shown, the lower part of the pot body 1 is provided with a groove 11. Specifically, the groove 11 is arranged around the side wall of the pot body 1 and near the bottom of the pot body 1. The cross-section of the groove 11 includes a first inclined surface 111, a vertical surface 112, and a second inclined surface 113. The first inclined surface 111, the vertical surface 112, and the second inclined surface 113 form a concave groove. The first inclined surface 111 is an inclined surface, and the second inclined surface is an arc-shaped inclined surface. By setting this specific groove 11 structure, the pot body base 2 and the pot body 1 are coupled and fastened internally and externally and vertically. That is, the pot body base 2 is fixedly installed at the bottom of the pot body 1 through the groove 11.

[0042] Furthermore, such as Figure 1 As shown, the kettle base 2 includes a shell 21, a heating structure, and a clamp 23. Specifically, the heating structure consists of a heating plate 22 and a high-temperature resistant coupler 24. The high-temperature resistant coupler 24 is divided into a female end and a male end. The female end is installed inside the kettle base 1, and the female end is installed inside the power supply base 3. The two are coaxially arranged and work together to connect the kettle base 2 to the power supply and heat or keep the kettle 1 warm. Specifically, the high-temperature resistant coupler 24 is an integrated coupler, specifically model Huilide KSD-568A. It is a high-temperature resistant coupler 24 that integrates a snap-action temperature controller and a thermal fuse, which can effectively improve its heat resistance temperature. Under normal circumstances, it can withstand a high temperature of 220℃, while ordinary couplers need to be electrically connected to the snap-action temperature controller and the thermal fuse separately, and can only withstand a maximum temperature of 150℃. The high-temperature resistant coupler 24 is fixedly installed at the bottom of the heating plate 22. Specifically, the heating plate 22 is made of die-cast aluminum. Since the high-temperature resistant coupler 24 can withstand high temperatures, it can be directly fixed to the bottom of the heating plate 22 and electrically connected by screws, thereby saving installation steps and making production and installation simpler and faster, effectively improving production efficiency.

[0043] Furthermore, such as Figure 1 , Figure 3 As shown, the bottom of the outer casing 21 has a mounting port, the diameter of which is adapted to the diameter of the high-temperature coupler 24. The high-temperature coupler 24 is fixedly installed inside the outer casing 21 with screws, corresponding to the position of the mounting port. In other words, the heating plate 22 is fixedly installed inside the outer casing 21 with screws via the high-temperature coupler 24. After installation, the top surface of the heating plate 22 is opposite to the bottom surface of the kettle body 1. Specifically, the outer casing 21 has a second connecting post 212, and the high-temperature coupler 24 has a coupler mounting ear 241 corresponding to the position of the second connecting post 212. During installation, the two are positioned correspondingly and fixed with screws.

[0044] Furthermore, the clamp 23 encircles the groove 11 and is fitted and installed in conjunction with the outer shell 21, so that the heating plate 22 is tightly attached to the bottom surface of the kettle body 1. Specifically, the outer shell 21 is provided with a first connecting post 211, and the clamp 23 is provided with a clamp connecting post 237 corresponding to the position of the first connecting post 211. The first connecting post 211 and the clamp connecting post 237 abut against each other and are fixed together by screws. The clamp 23 fixes the outer shell to the bottom of the kettle body 1, and the distance between the outer shell 21 and the bottom of the kettle body 1 is tightened upward by screws.

[0045] Furthermore, the clamp 23 is ring-shaped and connected end to end. Its first end has a first mounting ear 231, and its last end has a second mounting ear 232. A screw passes through the first and second mounting ears 232 to fasten and fix the clamp 23, thereby limiting its lateral movement and ensuring it is embedded within the groove 11 without loosening. Moreover, for aesthetic purposes and to prevent screw heads from protruding and causing short circuits due to wiring collisions, the first mounting ear 231 has a bevel 233 adapted to the screw head, allowing the screw to be fully screwed in and effectively concealing the screw head.

[0046] Furthermore, such as Figure 4 As shown, since the kettle body 1 is an all-glass structure, it may experience thermal expansion and contraction when heated. Because the kettle body 1 and the clamp 23 are made of different materials (the clamp 23 is mostly made of metal), their thermal expansion rates are inconsistent, which could easily cause the kettle body 1 to crack during heating. To avoid this, the clamp 23 is equipped with an elastic element 25 made of silicone. This elastic element 25, in conjunction with the clamp 23, provides a buffering effect of elastic stretching when the kettle body 1 expands due to heat, thus accommodating the thermal expansion and contraction of the kettle body 1. Specifically, the elastic element 25 and the clamp 23 are connected end-to-end to form a ring shape, embedded in the groove 11. That is, the elastic element 25 connects to the first and last ends of the clamp 23, and the connection method is screw fixing. The screw passes sequentially through the first mounting ear 231, the elastic element 25, and the second mounting ear 232 to connect and fix the clamp 23 and the elastic element 25.

[0047] Furthermore, the elastic element 25 has gaskets 251 extending outwards on both sides. Since the clamp 23 is made of metal, it is fixed by screws when tightened. Its head and tail ends can easily put pressure on the pot body 1, causing damage or breakage. The gaskets 251 can provide a buffering effect. Specifically, the inner wall of the clamp 23 has a gasket groove 238 corresponding to the position of the gasket 251. The gasket 251 is fitted into the gasket groove 238 to buffer the pressure on the pot body 1 when the clamp 23 is tightened, thereby protecting the pot body 1.

[0048] Furthermore, such as Figure 1 , Figure 3As shown, the clamp 23 is L-shaped, with a clamping edge 234 and an outward-flared edge 235. The clamping edge 234 is fitted to fit the shape of the groove 11 and is set close to the inner wall of the groove 11. The outward-flared edge 235 folds outward from the top of the clamping edge 234 and abuts against the top of the groove 11, that is, it fits and abuts against the first inclined surface 111, playing a supporting and limiting role, so that the clamp 23 is fixed in the groove 11 in the vertical direction. Specifically, the clamp connecting post 237 extends downward from the bottom surface of the outward-flared edge 235 and is integrally formed with it. The outer circumference of the clamp connecting post 237 is close to the outer wall of the clamping edge 234, so that the connection between the clamp connecting post 237 and the clamp 23 is tighter, and the clamp connecting post 237 provides better support and bearing capacity for the clamp 23.

[0049] Furthermore, such as Figure 1 , Figure 7 As shown, a connecting strap 26 is provided between the kettle body 1 and the outer shell 21. The connecting strap 26 is ring-shaped and has a slot 261 at its bottom. The top of the outer shell 21 is fitted into the slot 261. The inner edge of the connecting strap 26 matches the outer edge of the kettle body 1 to form an inner / outer and upper / lower fastening structure, used to transition the connection between the upper edge of the outer shell 21 and the kettle body 1. Specifically, the connecting strap 26 can be made of metal to make the connection smoother and serve a decorative purpose, or it can be made of silicone to provide cushioning, shock absorption, and sealing, preventing water from overflowing outwards and entering the interior through the gap between the kettle body 1 and the outer shell 21 when the kettle body 1 is full or boiling, thus preventing damage to electrical components.

[0050] In this embodiment, the heating plate 22 is directly screwed to the high-temperature resistant coupler 24, the high-temperature resistant coupler 24 is directly screwed to the outer shell 21, the outer shell 21 is directly screwed to the clamp 23, and the clamp 23 is directly embedded in the groove 11 for limiting, so that the installation between the kettle body 1 and the kettle body base 2 is simple and tight, so that the heating plate 22 is always in close contact with the bottom surface of the kettle body 1 to heat and keep it warm.

[0051] Example 2:

[0052] like Figure 5 , Figure 6As shown, unlike Embodiment 1, the clamp 23 is Z-shaped and has a clamping edge 234, an outer flange 235, and an inner flange 236. The clamping edge 234 is adapted to the shape of the groove 11 and is set close to the inner wall of the groove 11. The outer flange 235 is folded outward from the top of the clamping edge 234 and abuts against the top of the groove 11, that is, it is adapted to fit and abut against the first inclined surface 111, which plays the role of lifting and limiting, so that the clamp 23 is fixed in the groove 11 in the upper and lower directions. The inward folding edge 236 folds inward from the bottom of the clamping edge 234 and fits onto the bottom surface of the heating plate 22, limiting the heating plate 22 in the vertical and horizontal directions, so that the heating plate 22 is in close contact with the bottom of the kettle body 1, further ensuring its heating efficiency to the kettle body 1, and preventing the heating plate 22 from tilting or shifting if the screws between the heating plate 22 and the high-temperature coupler 24 or between the high-temperature coupler 24 and the outer shell 21 become loose, which would affect the heating effect or even normal use.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. All technical solutions that those skilled in the art can obtain based on the concept of the present utility model and on the basis of the prior art through logical analysis, reasoning or limited experiments should be within the protection scope determined by the claims.
