Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an installation structure for installing a temperature sensing module. Background Technology

[0002] A range hood, also known as a cooking hood, is an appliance installed above a kitchen stove to purify the kitchen environment. It quickly removes waste from combustion and harmful fumes produced during cooking, expelling them outdoors, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions. It effectively protects the kitchen environment and human health.

[0003] Existing range hoods are equipped with temperature sensing modules to monitor the temperature of the cooking area, allowing the range hood to make timely adjustments. The temperature sensing module includes a temperature sensor probe and a circuit board for processing the signal detected by the temperature sensor probe. To facilitate the installation of the temperature sensor probe, it is usually fixed to the circuit board, and then the circuit board is fixed to the mounting bracket of the range hood to complete the installation of the temperature sensor probe.

[0004] However, setting corresponding positioning holes on the circuit board and the mounting base for positioning and assembly will take a lot of time during assembly to align the positioning holes on the temperature sensor probe and the positioning holes on the mounting base. Otherwise, assembly may not be completed, resulting in low assembly efficiency. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an installation structure for installing a temperature sensing module, which effectively improves the assembly efficiency of the temperature sensing probe.

[0006] The above-mentioned technical problems are solved by the following technical solutions: An installation structure for mounting a temperature sensing module, the temperature sensing module including a circuit board and a temperature sensing probe fixed on the circuit board, the circuit board having a second positioning hole, the installation structure including a fixing base, the upper surface of the fixing base having a first positioning hole corresponding to the second positioning hole; The upper surface of the fixing base is inclined, and a first positioning edge is protruding on the fixing base. The first positioning edge is located at the lowest point of the upper surface of the fixing base, and the extension direction of the first positioning edge is perpendicular to the inclination direction of the upper surface of the fixing base. When the circuit board is placed on the upper surface of the fixing base, the first positioning edge is in contact with the side wall of the circuit board, and the vertical distance between the first positioning edge and the first positioning hole is equal to the vertical distance between the first positioning edge and the second positioning hole. Compared with the prior art, the temperature sensing module installation structure of this utility model has the following advantages: By setting a first positioning edge on the fixing base, the first positioning edge protrudes from the lowest point of the upper surface of the fixing base. In this way, when assembling the circuit board to the fixing base, the side wall of the circuit board can be pre-aligned with the first positioning edge. Since the vertical distance between the first positioning edge and the first positioning hole is equal to the vertical distance between the first positioning edge and the second positioning hole, the circuit board only needs to be moved along the extension direction of the first positioning edge to align with the first positioning hole and the second positioning hole. The operator does not need to spend a lot of time aligning the first positioning hole and the second positioning hole, resulting in higher assembly efficiency. At the same time, since the circuit board and the fixing base are generally fixed by screws, the circuit board is prone to rotation during the screwing process. By setting the first positioning edge, the circuit board can be resisted and prevented from rotating and slipping, ensuring the assembly effect. Furthermore, since the upper surface of the fixing base is inclined, the temperature sensing probe can also be tilted to face the corresponding stove area to detect the temperature.

[0007] In one embodiment, the fixing base is provided with a second positioning edge, which is disposed adjacent to the first positioning edge; When the circuit board is placed on the upper surface of the fixing base, the first positioning edge and the second positioning edge are respectively attached to the two adjacent side walls of the circuit board in a one-to-one correspondence, and the vertical distance between the second positioning edge and the first positioning hole is equal to the vertical distance between the second positioning edge and the second positioning hole.

[0008] In one embodiment, the first positioning edge and the second positioning edge are arranged perpendicularly, and the two adjacent sidewalls of the circuit board are arranged perpendicularly.

[0009] In one embodiment, the first positioning edge and the second positioning edge are arranged in an L-shape, wherein the first positioning edge is the short edge and the second positioning edge is the long edge; The two adjacent sidewalls of the circuit board are arranged in an L-shape, each sidewall including a long side and a short side. The long sidewall of the circuit board corresponds to the second positioning side, and the short sidewall of the circuit board corresponds to the first positioning side.

[0010] In one embodiment, an overlap area is formed between the inner side of the first positioning edge and the upper surface of the corresponding fixing seat, and the circuit board is disposed on the overlap area.

[0011] In one embodiment, the inner side of the second positioning edge abuts against the outer side of the circuit board.

[0012] In one embodiment, there are two first positioning holes, and the two first positioning holes are arranged asymmetrically. There are two second positioning holes, which are arranged asymmetrically.

[0013] In one embodiment, the two second positioning holes are respectively disposed on both sides of the circuit board, and the line connecting the two second positioning holes is not intersecting with the center point of the circuit board.

[0014] In one embodiment, the fixing base includes a fixing body and an insertion structure disposed within the fixing body.

[0023] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0024] According to an embodiment of the present invention, in one aspect, an installation structure for installing a temperature sensing module is provided. The temperature sensing module includes a circuit board 2 and a temperature sensing probe 1 fixed on the circuit board 2. The circuit board 2 is provided with a second positioning hole 201. The mounting structure 100 includes a fixing base 3, and the upper surface of the fixing base 3 is provided with a first positioning hole 304 corresponding to the second positioning hole 201. The upper surface of the fixing base 3 is inclined, and a first positioning edge 301 is protruding on the fixing base 3. The first positioning edge 301 is located at the lowest point of the upper surface of the fixing base 3, and the extension direction of the first positioning edge 301 is perpendicular to the inclination direction of the upper surface of the fixing base 3. When the circuit board 2 is placed on the upper surface of the mounting base 3, the first positioning edge 301 is in contact with the side wall of the circuit board 2, and the vertical distance between the first positioning edge 301 and the first positioning hole 304 is equal to the vertical distance between the first positioning edge 301 and the second positioning hole 201. By setting a first positioning edge 301 on the fixing base 3, the first positioning edge 301 protrudes from the lowest point of the upper surface of the fixing base 3. When assembling the circuit board 2 onto the fixing base 3, the second positioning edge 305 of the circuit board 2 can be pre-aligned with the first positioning edge 301. Since the vertical distance between the first positioning edge 301 and the first positioning hole 304 is equal to the vertical distance between the first positioning edge 301 and the second positioning hole 201, the circuit board only needs to be moved along the extension direction of the first positioning edge to align with the first positioning hole 304 and the second positioning hole 201. This eliminates the need for the operator to spend a lot of time aligning the first positioning hole 304 and the second positioning hole 201, resulting in high assembly efficiency. At the same time, since the circuit board 2 and the fixing base 3 are generally fixed by screws, the circuit board 2 is prone to rotation during the screw-tightening process. By setting the first positioning edge 301, the circuit board 2 can be resisted to prevent it from rotating and slipping, ensuring the assembly effect. Furthermore, since the upper surface of the fixing base is tilted, the temperature sensor can also be tilted to face the corresponding stove area to detect the temperature.

[0025] Specifically, circuit board 2 is a PCB board.

[0026] like Figure 3 and Figure 4 As shown, a second positioning edge 305 protrudes from the fixed base 3, and the second positioning edge 305 is arranged adjacent to the first positioning edge 301; When the circuit board 2 is placed on the upper surface of the fixing base 3, the first positioning edge 301 and the second positioning edge 305 are respectively attached to the two adjacent side walls of the circuit board 2 in a one-to-one correspondence, and the vertical distance between the second positioning edge 305 and the first positioning hole 304 is equal to the vertical distance between the second positioning edge 305 and the second positioning hole 201.

[0027] By providing a second positioning edge 305 protruding from the fixing base 3, and with the second positioning edge 305 being adjacent to the first positioning edge 301, the circuit board 2 and the fixing base 3 can be positioned in both directions. This ensures that when the first positioning edge 301 and the second positioning edge 305 of the fixing base 3 are respectively attached to the two adjacent sidewalls of the circuit board 2, the first positioning hole 304 and the second positioning hole 201 are aligned because the vertical distance between the second positioning edge 305 and the first positioning hole 304 is equal to the vertical distance between the second positioning edge 305 and the second positioning hole 201.

[0028] As an alternative implementation, the fixed base 3 may only have a first positioning edge 301.

[0029] In one embodiment, the first positioning edge 301 and the second positioning edge 305 are vertically arranged, and the two adjacent sidewalls of the circuit board 2 are also vertically arranged. By vertically arranging the first positioning edge 301 and the second positioning edge 305, and the two adjacent sidewalls of the circuit board 2, the design of the circuit board 2 is facilitated, and the assembly of the circuit board 2 with the mounting base 3 is also facilitated. Alternatively, the first positioning edge 301 and the second positioning edge 305 may be arranged at other angles, and this angle may be the same as the included angle between the two adjacent sidewalls of the circuit board 2.

[0030] Specifically, the first positioning edge 301 and the second positioning edge 305 are arranged in an L-shape, wherein the first positioning edge 301 is the short edge and the second positioning edge 305 is the long edge; The two adjacent sidewalls of the circuit board 2 are arranged in an L-shape. The two adjacent sidewalls of the circuit board 2 include a long side and a short side. The long side of the circuit board 2 is arranged to correspond to the second positioning side 305, and the short side of the circuit board 2 is arranged to correspond to the first positioning side 301.

[0031] By arranging the first positioning edge 301 and the second positioning edge 305 in an L-shape, the two adjacent sidewalls of the circuit board 2 are also arranged in an L-shape, including a long side and a short side. When assembling the circuit board 2 onto the fixing base 3, the first positioning edge 301 and the short sidewall of the circuit board 2 can be aligned, and the second positioning edge 305 and the long sidewall of the circuit board 2 can be aligned. This facilitates assembly. Since the first positioning edge 301 and the second positioning edge 305 are arranged with one long and one short sidewall, the two adjacent sidewalls of the circuit board 2 are also arranged with one long and one short sidewall. If the arrangement is reversed during assembly, i.e., the first positioning edge 301 is aligned with the long sidewall of the circuit board 2 and the second positioning edge 305 is aligned with the short sidewall of the circuit board 2, the circuit board 2 may overlap the first positioning edge 301 and cannot be assembled horizontally on the fixing base 3. This would prevent the circuit board 2 from working properly. Therefore, the arrangement of the first positioning edge 301 and the second positioning edge 305 can also play a certain role in preventing mistakes.

[0032] Alternatively, the lengths of the first positioning edge 301 and the second positioning edge can be the same, and the lengths of the two adjacent sidewalls of the circuit board 2 can be the same.

[0033] like Figure 3 and Figure 4 As shown, an overlap area 3021 is formed between the inner side of the first positioning edge 301 and the upper surface of the corresponding fixed seat 3, and the circuit board 2 is disposed on the overlap area 3021.

[0034] By providing an overlap area 3021 between the inner side of the first positioning edge 301 and the upper surface of the fixing base 3, it is convenient to place the circuit board 2 on the overlap area 3021, which can increase the contact area between the fixing base 3 and the circuit board 2 and improve the assembly stability.

[0035] As an alternative implementation, the short side of the first positioning edge 301 may not have an overlap area 3021 between it and the upper surface of the fixing base 3. Instead, the outer side of the short side of the circuit board 2 may be abutted against the inner side of the first positioning edge 301 of the fixing base 3.

[0036] like Figure 3 and Figure 4 As shown, the inner side of the second positioning edge 305 is abutted against the outer side of the circuit board 2.

[0037] By setting the inner side of the second positioning edge 305 to abut against the outer side of the circuit board 2, there is no need to set an overlapping area between the second positioning edge 305 and the upper surface of the fixing seat 3, which can reduce the setting area of ​​the fixing seat 3 and reduce material costs.

[0038] Alternatively, an overlap area may be provided between the second positioning edge 305 and the upper surface of its corresponding fixing seat 3.

[0039] like Figure 2 As shown, the circuit board 2 is rectangular, and the two adjacent sidewalls of the circuit board 2 are the long side and the short side of one of the adjacent sides of the rectangle.

[0040] like Figure 2 and Figure 3 As shown, there are two first positioning holes 304, and the two first positioning holes 304 are arranged asymmetrically; There are two second positioning holes 201, and the two second positioning holes 201 are arranged asymmetrically.

[0041] By setting two first positioning holes 304, and the two first positioning holes 304 are asymmetrically arranged, and setting two second positioning holes 201, and the two second positioning holes 201 are asymmetrically arranged, a foolproof function can be played when assembling the circuit board 2 to the fixing seat 3. If the operator misoperates and fails to assemble the corresponding first positioning holes 304 and second positioning holes 201, the first positioning holes 304 and second positioning holes 201 cannot be aligned. In this way, when screws are driven into the first positioning holes 304 and second positioning holes 201 for fixing, the screws will not be exposed, and effective assembly cannot be achieved.

[0042] Alternatively, the first positioning hole 304 may have three or more holes, and the second positioning hole 201 may have three or more holes.

[0043] like Figure 2As shown, two second positioning holes 201 are respectively provided on both sides of the circuit board 2, and the line connecting the two second positioning holes 201 is not intersected with the center point of the circuit board 2.

[0044] Specifically, the circuit board 2 is rectangular in shape, with one second positioning hole 201 located near the junction of one long side and one short side of the rectangle, and the other second positioning hole 201 located on the other long side of the rectangle, but the line connecting the two second positioning holes 201 does not pass through the center point of the circuit board 2.

[0045] Alternatively, the two second positioning holes 201 can be located at other positions on the circuit board 2, as long as they are asymmetrically arranged.

[0046] like Figure 3 As shown, the fixing base 3 includes a fixing body 302 and an insertion structure 303 disposed in the fixing body 302. The insertion structure 303 is provided with a hollow insertion hole, and the temperature sensing probe 1 is inserted into the insertion hole. One of the two first positioning holes 304 is disposed on the surface of the fixing body 302, and the other is disposed on the surface of the insertion structure 303.

[0047] Specifically, one of the two first positioning holes 304 is located at the connection between two adjacent sides of the fixed body 302. The insertion structure 303 includes an insertion body 3031 and a connecting part 3032. The insertion hole is located on the insertion body 3031. One end of the connecting part 3032 is connected to the insertion body 3031, and the other end is connected to the fixed body 302. One of the first positioning holes 304 is located on the surface of the connecting part 3032. A gap is provided between the outer side of the insertion body 3031 and the inner side of the fixed body 302.

[0048] By setting the insertion structure 303 to include an insertion body 3031 and a connecting part 3032, the connecting part 3032 connects the insertion body 3031 to the fixed body 302, which can ensure the overall connection strength, and at the same time facilitates the setting of an insertion hole and one of the first positioning holes 304 on the insertion structure 303.

[0049] By placing one of the two first positioning holes 304 at the connection between two adjacent sides of the fixing body 302, and placing the other first positioning hole 304 on the surface of the connecting part 3032, the foolproof effect of the two first positioning holes 304 is improved, and multiple connecting parts 3032 are not required on the fixing seat 3. Furthermore, by setting a gap between the outer side of the insertion body 3031 and the inner side of the fixing body 302, i.e., by providing a hollow part between the insertion body 3031 and the fixing body 302, material can be saved to the greatest extent without affecting the installation. Moreover, when the fixing seat 3 and the range hood panel are integrally injection molded, the hollow part between the insertion body 3031 and the fixing body 302 can reduce the thickness of the wall of the fixing seat 3, avoiding the imbalance of cooling rate caused by the large difference between the thickness of the wall of the fixing seat 3 and the thickness of the range hood panel during the injection molding cooling stage. In this way, during the injection molding cooling stage, the thick area of ​​the fixing seat 3 and the thin area of ​​the range hood panel can complete the cooling and solidification at a relatively similar rate, thereby preventing the residual stress in the thick area from pulling on the thin area and causing deformation problems such as warping and denting of the panel. This ensures that the flatness of the range hood panel meets the design requirements and lays the foundation for the precise assembly of the temperature sensing module in the future.

[0050] As an alternative implementation, the two first positioning holes 304 can also be located in other positions of the fixing base 3, as long as they are asymmetrically arranged. No further restrictions are imposed here.

[0051] The upper surface of the fixing body 302 of the fixing base 3 and the upper surface of the insertion structure 303 are coplanar, so that when the circuit board 2 is assembled on the fixing base 3, the lower surface of the circuit board 2 fits against the upper surface of the fixing body 302 without any gap between them. The first positioning edge 301 and the second positioning edge 305 protrude from the upper surface of the fixing body 302. The first positioning edge 301, the second positioning edge 305 and the fixing body 302 form an installation space to accommodate the circuit board 2. Since the circuit board 2 is rectangular, the installation space formed between the fixing body 302 and the first positioning edge 301 is also rectangular to better match the circuit board 2.

[0052] During actual assembly, the short side of the circuit board 2 can be placed against the first positioning edge 301 of the fixing base 3, and the long side of the circuit board 2 can be placed against the second positioning edge 305 of the fixing base 3. This ensures that the lower surface of the circuit board 2, where the temperature sensor 1 is located, is completely in contact with the upper surface of the fixing base 3. At this time, the two first positioning holes 304 on the fixing base 3 and the two second positioning holes 201 on the circuit board 2 can be aligned one-to-one, achieving the effect of quick edge assembly and quick positioning. Furthermore, since the short side of the circuit board 2 abuts against the first positioning edge 301 of the fixing base 3, and the long side of the circuit board 2 abuts against the second positioning edge 305 of the fixing base 3, when the circuit board 2 and the fixing base 3 are correctly installed, the two adjacent sidewalls of the circuit board 2 are parallel to the first positioning edge 301 and the second positioning edge 305 of the fixing base 3 without any gap. When screws are used for fixing, the temperature sensor module will not rotate due to the mechanical stress of the screw rotation, thus speeding up the installation efficiency of the temperature sensor module and the fixing base 3.

[0053] According to an embodiment of the present invention, another aspect provides a range hood, including a housing 200, a temperature sensing module, and the aforementioned mounting structure 100 for mounting the temperature module. The mounting structure 100 is disposed within the housing 200. Figure 5 As shown.

[0054] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0055] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
