Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to heating components and household appliances. Background Technology

[0002] For electrical appliances with heating functions, PTC elements (such as PTC ceramic discs) are the core heating components and are typically fixed in the equipment using injection-molded brackets. PTC brackets are usually injection-molded from engineering plastics (such as nylon or polycarbonate) to reduce cost and weight. However, during PTC element operation, due to the concentrated localized heat generation when current flows, the contact point between the PTC bracket and the PTC element (i.e., the mating surface between the PTC bracket and the PTC element) is highly susceptible to overheating, leading to scorching and melting. Therefore, PTC brackets need to have high-temperature resistance, but high-temperature resistant materials are difficult to use for molding complex parts and are also costly. Summary of the Invention

[0003] In view of this, the present invention provides a heating component and a household appliance to solve the problem that the contact point between the PTC bracket and the PTC element is prone to burning and melting due to overheating.

[0004] In a first aspect, the present invention provides a heating component, comprising: The heating bracket has multiple support positions, and each support position has mounting holes. A buffer component is provided at the support position. The buffer component includes a buffer body and a connecting part provided at the buffer body. The connecting part is provided with a fastening part. After the connecting part passes through the mounting hole, the fastening part abuts against the side of the support position away from the buffer body. The heating element is supported on the buffer.

[0005] Beneficial effects: By setting a buffer element on the support position, the heating element is supported on the buffer element, and the heating element and the support position are separated by the buffer element. This prevents localized heat concentration when the heating element current passes through, which could cause the support position to overheat and burn or melt. Because the heating element and the support position are separated by the buffer element, the heating bracket can be made of a material with relatively low heat resistance, which is convenient for the heating bracket to be formed and can reduce material costs. The buffer element can be made of a material with high heat resistance, and because the buffer element is relatively small, it is easy to process and manufacture. By setting a mounting hole in the support position and providing a fastening part in the connecting part, after the connecting part passes through the mounting hole, the fastening part abuts against the side of the support position away from the buffer body, thereby fixing the buffer body to the support position and facilitating the assembly of the buffer element.

[0006] In one alternative embodiment, the connecting portion includes at least two cantilever rods spaced apart, and the fastening portion is located at the end of the cantilever rods.

[0007] Beneficial effects: The connecting part includes at least two cantilever rods spaced apart, and the fastening part is located at the end of the cantilever rod. Therefore, at least two cantilever rods can retract to a certain extent. When assembling the buffer, the lower ends of at least two cantilever rods are first gathered together, so that the buckle can enter the mounting hole and apply downward pressure to the buffer body, so that the fastening part and the connecting part pass through the mounting hole. After the fastening part passes through the mounting hole, at least two cantilever rods return to their initial state. The fastening part abuts against the side of the support position away from the buffer body, and the connecting part is not easy to come out of the mounting hole, thereby fixing the buffer to the support position.

[0008] In one alternative implementation, the buffer body and the support position are connected by a positioning structure.

[0009] Beneficial effects: The support position is provided with a mounting hole, and the connecting part is provided with a fastening part. After the connecting part passes through the mounting hole, the fastening part abuts against the side of the support position away from the buffer body. At the same time, the buffer body and the support position are connected by a positioning structure, which can prevent the position of the buffer body from shaking and fix the buffer body on the support position.

[0010] In one optional embodiment, the positioning structure includes a mounting track and a mounting groove. The mounting track is disposed in one of the support position and the buffer body, and the mounting groove is disposed in the other of the support position and the buffer body. The shape of the mounting track is adapted to the mounting groove, and the mounting track is adapted to be embedded in the mounting groove. The extending direction of the mounting track is parallel to the extending direction of the mounting hole.

[0011] Beneficial effects: The positioning structure includes a mounting track and a mounting groove. The mounting track is located in one of the support position and the buffer body, and the mounting groove is located in the other of the support position and the buffer body. The shape of the mounting track and the mounting groove are adapted to each other. The extension direction of the mounting track is parallel to the extension direction of the mounting hole. Therefore, when assembling the buffer, the mounting track and the mounting groove are aligned in the vertical direction. When the mounting track and the mounting groove are aligned, the connecting part and the mounting hole are also aligned synchronously. Then, a downward pressure is applied to the buffer, and the mounting track enters into the mounting groove. The two slide relative to each other, and the connecting part gradually passes through the mounting hole. When the buffer body abuts against the support position, the fastening part abuts against the side of the support position away from the buffer body.

[0012] In one alternative embodiment, the mounting groove is a dovetail groove.

[0013] Beneficial effects: The mounting groove is a dovetail groove, and the shape of the mounting track is adapted to the shape of the mounting groove. Therefore, the mounting track can only move relative to the mounting groove in the vertical direction, and cannot detach from the mounting groove in other directions.

[0014] In one alternative embodiment, the buffer body is L-shaped, including a horizontal portion and a vertical portion, and the heating element is adapted to be supported on the horizontal portion.

[0015] Beneficial effects: Since the buffer body is L-shaped, including a horizontal part and a vertical part, the buffer can have a heating element and a heating support spaced apart in the horizontal and vertical directions, which prevents the local heat from concentrating when the current passes through the heating element, which may cause the support to burn or melt due to overheating.

[0016] In one alternative embodiment, one of the mounting track and the mounting groove is located in the vertical portion.

[0017] Beneficial effects: One of the mounting rails and mounting slots is located in the vertical part. Since the vertical part has a certain height, the mounting rails or mounting slots can have a certain length, thereby ensuring the assembly stability of the buffer and the support.

[0018] In one alternative embodiment, the heat resistance of the buffer is higher than that of the heating bracket.

[0019] Beneficial effects: The heat resistance of the buffer component is higher than that of the heating bracket. The heating bracket can be made of materials with relatively low heat resistance, which makes it easier to form the heating bracket and reduces material costs. The buffer component can be made of materials with high heat resistance. Since the buffer component is relatively small, it is easy to process and manufacture.

[0020] In a second aspect, the present invention also provides an electrical device, comprising: The aforementioned heating element.

[0021] Beneficial effects: This electrical device, by incorporating a buffer at the support position, with the heating element supported on the buffer and separated from the support position by the buffer, prevents localized heat concentration when current flows through the heating element, thus preventing the support position from overheating and burning or melting. Because the heating element and support position are separated by the buffer, the heating bracket can be made of a material with relatively low heat resistance, facilitating its molding and reducing material costs. Conversely, the buffer can be made of a material with high heat resistance, and its relatively small size facilitates its processing and manufacturing. Attached Figure Description

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] For electrical appliances with heating functions, PTC elements (such as PTC ceramic discs) are the core heating components and are typically fixed in the equipment using injection-molded brackets. PTC brackets are usually injection-molded from engineering plastics (such as nylon or polycarbonate) to reduce cost and weight. However, during PTC element operation, due to the concentrated localized heat generation when current flows, the contact point between the PTC bracket and the PTC element (i.e., the mating surface between the PTC bracket and the PTC element) is highly susceptible to overheating, leading to scorching and melting. Therefore, PTC brackets need to have high-temperature resistance, but high-temperature resistant materials are difficult to use for molding complex parts and are also costly.

[0030] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0031] According to an embodiment of the present invention, a heating component is provided, comprising: a heating bracket 1, a buffer 2, and a heating element 3.

[0032] The heating bracket 1 is provided with multiple support positions 101, and each support position 101 is provided with a mounting hole 1011; the buffer 2 is provided on the support position 101, and the buffer 2 includes a buffer body 201 and a connecting part provided on the buffer body 201. The connecting part is provided with a fastening part 203. After the connecting part passes through the mounting hole 1011, the fastening part 203 abuts against the side of the support position 101 away from the buffer body 201; the heating element 3 is supported on the buffer 2.

[0033] In this embodiment, by providing a buffer 2 on the support position 101, the heating element 3 is supported on the buffer 2, and the heating element 3 and the support position 101 are separated by the buffer 2. This prevents the local heat generation from concentrating when the current passes through the heating element 3, which could cause the support position 101 to easily overheat and burn or melt. Since the heating element 3 and the support position 101 are separated by the buffer 2, the heating bracket 1 can be made of a material with relatively low heat resistance, which is convenient for the heating bracket 1 to be formed and can reduce material costs. The buffer 2 can be made of a material with high heat resistance. Since the buffer 2 is relatively small, it is convenient for the processing and manufacturing of the buffer 2. The support position 101 is provided with a mounting hole 1011, and the connecting part is provided with a fastening part 203. After the connecting part passes through the mounting hole 1011, the fastening part 203 abuts against the side of the support position 101 away from the buffer body 201, thereby fixing the buffer body 201 on the support position 101 and facilitating the assembly of the buffer 2.

[0034] It should be noted that in related technologies, the heating element 3 is in direct contact with the support position 101. Therefore, when current flows through the heating element 3, the localized heat generation is concentrated, which can easily cause the support position 101 to overheat and burn or melt. Manufacturing the heating bracket 1 with a material that has high overall heat resistance would result in higher costs. Compared with related technologies, in this embodiment, the heating element 3 and the support position 101 are separated by a buffer 2, which can prevent the localized heat generation from the heating element 3 from concentrating and causing the support position 101 to overheat and burn or melt. Because the heating element 3 and the support position 101 are separated by the buffer 2, the heating bracket 1 can be made of a material with relatively low heat resistance, which facilitates the molding of the heating bracket 1 and reduces material costs. The buffer 2 can be made of a material with high heat resistance, and because the buffer 2 is relatively small, it is easy to process and manufacture.

[0035] In one specific embodiment, the heating bracket 1 has a square frame, and three walls of the square frame are provided with support positions 101. Each support position 101 is provided with a buffer 2. Another wall of the square frame is provided with a slot 102. The heating element 3 is supported on the buffer 2, and the terminals of the heating element 3 are supported in the slot 102.

[0036] Specifically, such as Figure 7 As shown, the slot 102 is V-shaped, which facilitates placing the terminals of the heating element 3 into the slot 102 and also limits the bottom of the terminals.

[0037] Specifically, each of the three walls of the square frame is provided with two support positions 101, so there are a total of six support positions 101, which can support the left and right sides and one end of the heating element 3.

[0038] In one specific embodiment, the heating element 3 is a PTC element.

[0039] Specifically, such as Figure 8 As shown, the axis of the mounting hole 1011 extends vertically. When assembling the buffer 2, the connecting part passes through the mounting hole 1011 from top to bottom. After the connecting part passes through the mounting hole 1011, the fastening part 203 abuts against the side of the support position 101 away from the buffer body 201. The connecting part is not easy to come out of the mounting hole 101, thereby fixing the buffer 2 on the support position 101.

[0040] In an alternative embodiment, the support 101 is provided with a fixing groove, and the side wall of the fixing groove is provided with a buckle. When the buffer 2 is assembled, pressure is applied to the buffer 2 from top to bottom, so that the buffer 2 is embedded in the fixing groove and fixed by the buckle.

[0041] In one embodiment, the connecting portion includes at least two cantilever rods 202 spaced apart, and the fastening portion 203 is provided at the end of the cantilever rod 202.

[0042] In this embodiment, the connecting part includes at least two cantilever rods 202 spaced apart, and the fastening part 203 is provided at the end of the cantilever rod 202. Therefore, at least two cantilever rods 202 can retract to a certain extent. When assembling the buffer 2, the lower ends of at least two cantilever rods 202 are first gathered together, so that the buckle can enter the mounting hole 1011 and apply downward pressure to the buffer body 201, so that the fastening part 203 and the connecting part pass through the mounting hole 1011. After the fastening part 203 passes through the mounting hole 1011, at least two cantilever rods 202 return to the initial state. The fastening part 203 abuts against the side of the support position 101 away from the buffer body 201, and the connecting part is not easy to come out of the mounting hole 1011, thereby fixing the buffer 2 on the support position 101.

[0043] Specifically in one embodiment, such as Figure 9 and Figure 11 As shown, the connecting part includes two cantilever rods 202 spaced apart. The two cantilever rods 202 are symmetrically arranged with a gap between them. The fastening part 203 is provided at the end of the cantilever rod 202. When assembling the buffer 2, the lower ends of the two cantilever rods 202 are first gathered together, so that the fastening part 203 can enter the mounting hole 1011 and apply downward pressure to the buffer body 201, so that the fastening part 203 and the connecting part pass through the mounting hole 1011. After the fastening part 203 passes through the mounting hole 1011, the two cantilever rods 202 return to their initial state. The fastening part 203 abuts against the side of the support position 101 away from the buffer body 201, and the connecting part is not easy to come out of the mounting hole 1011, thereby fixing the buffer 2 on the support position 101.

[0044] In a preferred embodiment, the cross-section of the cantilever 202 is semi-circular, and when two cantilever 202s are joined together, they form a cylinder. Therefore, the outer surface of the fastening part 203 is spherical, and when two fastening parts 203 are joined together, they form a hemisphere. The outer diameter of the fastening part 203 is larger than the diameter of the mounting hole 1011. Therefore, when the fastening part 203 passes through the mounting hole 1011, the two cantilever 202s return to their initial state, and the fastening part 203 abuts against the side of the support position 101 away from the buffer body 201. The connecting part is not easily dislodged from the mounting hole 1011, thereby fixing the buffer 2 to the support position 101. Since the outer surface of the fastening part 203 is spherical, it can guide the fastening part 203 into the mounting hole 1011, allowing the fastening part 203 to smoothly enter and pass through the mounting hole 1011.

[0045] In one embodiment, the buffer body 201 and the support position 101 are connected by a positioning structure.

[0046] In this embodiment, the support position 101 is provided with a mounting hole 1011, and the connecting part is provided with a fastening part 203. After the connecting part passes through the mounting hole 1011, the fastening part 203 abuts against the side of the support position 101 away from the buffer body 201. At the same time, the buffer body 201 and the support position 101 are connected by a positioning structure, which can prevent the position of the buffer body 201 from shaking and fix the buffer body 201 on the support position 101.

[0047] In one embodiment, the positioning structure includes a mounting track 1012 and a mounting groove 204. The mounting track 1012 is disposed in one of the support position 101 and the buffer body 201, and the mounting groove 204 is disposed in the other of the support position 101 and the buffer body 201. The shape of the mounting track 1012 is adapted to the mounting groove 204. The mounting track 1012 is adapted to be embedded in the mounting groove 204. The extending direction of the mounting track 1012 is parallel to the extending direction of the mounting hole 1011.

[0048] In this embodiment, the positioning structure includes a mounting track 1012 and a mounting groove 204. The mounting track 1012 is located in one of the support position 101 and the buffer body 201, and the mounting groove 204 is located in the other of the support position 101 and the buffer body 201. The shapes of the mounting track 1012 and the mounting groove 204 are adapted to each other. The extension direction of the mounting track 1012 is parallel to the extension direction of the mounting hole 1011. Therefore, when assembling the buffer 2, the mounting track 1012 and the mounting groove 204 are aligned in the vertical direction. When the mounting track 1012 and the mounting groove 204 are aligned, the connecting part and the mounting hole 1011 are also aligned synchronously. Then, a downward pressure is applied to the buffer 2, and the mounting track 1012 enters into the mounting groove 204 and the two slide relative to each other. The connecting part gradually passes through the mounting hole 1011. When the buffer body 201 abuts against the support position 101, the fastening part 203 abuts against the side of the support position 101 away from the buffer body 201.

[0049] In one specific embodiment, the mounting track 1012 is located on the upper side of the support position 101 and close to the edge of the support position 101. The mounting track 1012 extends upward and the mounting groove 204 is located on the buffer body 201.

[0050] In one embodiment not shown in the figure, the mounting track 1012 can be disposed on the buffer body 201, and the mounting groove 204 can be disposed on the support position 101.

[0051] In an alternative embodiment, the positioning structure may include a positioning post and a positioning hole. The positioning post is located in one of the support position 101 and the buffer body 201, and the positioning hole is located in the other of the support position 101 and the buffer body 201. The extending direction of the positioning post is parallel to the extending direction of the mounting hole 1011, and the positioning post is adapted to be inserted into the positioning hole. When assembling the buffer 2, the positioning post and the positioning hole are aligned in the vertical direction. When the positioning post and the positioning hole are aligned, the connecting part is also aligned with the mounting hole 1011 simultaneously. Then, a downward pressure is applied to the buffer 2, and the positioning post is gradually inserted into the positioning hole. At the same time, the connecting part gradually passes through the mounting hole 1011. When the buffer body 201 abuts against the support position 101, the fastening part 203 abuts against the side of the support position 101 opposite to the buffer body 201.

[0052] In one embodiment, the mounting groove 204 is a dovetail groove.

[0053] In this embodiment, the mounting groove 204 is a dovetail groove, and the shape of the mounting track 1012 is adapted to the shape of the mounting groove 204. Therefore, the mounting track 1012 can only move relative to the mounting groove 204 in the vertical direction, and cannot detach from the mounting groove 204 in other directions.

[0054] Specifically, such as Figure 9 and Figure 10As shown, the mounting groove 204 is provided on the buffer body 201. On the horizontal projection plane, the mounting groove 204 is trapezoidal. The mounting groove 204 penetrates the buffer body 201 in the vertical direction, and the side opening of the mounting groove 204 is smaller than the bottom area of ​​the mounting groove 204.

[0055] In other alternative embodiments, the cross-section of the mounting slot 204 may be of other shapes, such as triangles, rectangles, etc.

[0056] In one embodiment, the buffer body 201 is L-shaped, including a horizontal part 2011 and a vertical part 2012, and the heating element 3 is adapted to be supported on the horizontal part 2011.

[0057] In this embodiment, since the buffer body 201 is L-shaped, including a horizontal part 2011 and a vertical part 2012, the buffer member 2 can be spaced apart in the horizontal and vertical directions to develop the heating element 3 and the heating support 1, so as to prevent the local heat generation from concentrating when the current passes through the heating element 3, which may cause the support position 101 to burn or melt due to overheating.

[0058] In one embodiment, there is a gap between the heating element 3 and the vertical part 2012, the gap being d, where d≤1.5mm, to prevent the heating element 3 from shaking significantly.

[0059] In one embodiment, one of the mounting rail 1012 and the mounting groove 204 is provided in the vertical portion 2012.

[0060] In this embodiment, one of the mounting track 1012 and the mounting groove 204 is located in the vertical part 2012. Since the vertical part 2012 has a certain height, the mounting track 1012 or the mounting groove 204 can have a certain length, thereby ensuring the assembly stability of the buffer 2 and the support position 101.

[0061] In one specific embodiment, the mounting groove 204 is provided in the vertical portion 2012.

[0062] In one embodiment, the heat resistance of the buffer 2 is higher than that of the heating bracket 1.

[0063] In this embodiment, the heat resistance of the buffer 2 is higher than that of the heating bracket 1. The heating bracket 1 can be made of a material with relatively low heat resistance, which is convenient for the heating bracket 1 to be formed and can reduce material costs. The buffer 2 can be made of a material with high heat resistance. Since the buffer 2 is relatively small in size, it is convenient to process and manufacture the buffer 2.

[0064] In addition, since manufacturing defects are prone to occur when using materials with high heat resistance to form more complex parts, the heating bracket 1 is made of a material with relatively low heat resistance, which can improve the production qualification rate of the heating bracket 1.

[0065] In one specific embodiment, the buffer 2 can be made of BMC material, and the heating bracket 1 can be made of materials such as PC and PA66-GF30.

[0066] According to an embodiment of the present invention, another aspect provides an electrical device including the heating component provided in the above embodiments.

[0067] This electrical device, by setting a buffer 2 on the support position 101, with the heating element 3 supported on the buffer 2 and the heating element 3 and the support position 101 separated by the buffer 2, can prevent the local heat concentration when the current passes through the heating element 3, which could easily cause the support position 101 to burn or melt due to overheating. Since the heating element 3 and the support position 101 are separated by the buffer 2, the heating bracket 1 can be made of a material with relatively low heat resistance, which is convenient for the heating bracket 1 to be formed and can reduce material costs. The buffer 2 can be made of a material with high heat resistance. Since the buffer 2 is relatively small in size, it is easy to process and manufacture.

[0068] In one embodiment, the electrical appliance may be an electric heater, an electric fan, a warm air blower, etc.

[0069] In one embodiment, the electrical device includes a base 4, a heating element is disposed in the base 4, and the base 4 is provided with a heat dissipation grille for heat dissipation.

[0070] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
