DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, rather than any limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] In the description of the utility model, it is understood that the orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship is usually based on the orientation or position relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, without making the opposite statement, these orientation words do not indicate and imply that the indicated device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the protection scope of the utility model; the orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0030] For purposes of the description hereinafter, spatial relative terms, such as "above", "below", "upper", "lower", and the like, can be used to describe the relative position of one element or feature to another element or feature as illustrated in the figures. It will be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if a device in the figures is inverted, elements described as "above" or "above" other elements or features would then be oriented "below" or "below" the other elements or features. Thus, the exemplary term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatial relative descriptors used herein interpreted accordingly.

[0031] In addition, it should be noted that the use of "first", "second", and the like words of distinction do not have a special meaning, and are only used to distinguish corresponding parts, and therefore cannot be understood as limiting the scope of protection of the utility model.

[0032] The utility model provides a kind of temperature sensor fixing, compressor, air conditioner and refrigerator, it can solve the technical problem of temperature sensor in prior art to the temperature detection of compressor not sensitive.

[0033] Referring to Figures 1-8 As shown in the figure, a kind of temperature sensor fixing 2 is fixed on metal piece, temperature sensor 1 fixing includes connecting portion 201 and installation portion 202, the connecting portion 201 is fixed together with the metal piece, the installation portion 202, the installation portion 202 is provided with mounting hole 203, the side wall of the mounting hole 203 is provided with the deformation joint 204 extending along the axial direction of the mounting hole 203, temperature sensor 1 can be set in the mounting hole 203 to the temperature of the metal piece and detect.

[0034] Temperature sensor 1 is inserted into mounting hole 203 with interference, so that installation portion 202 is deformed, expansion joint is enlarged, correspondingly, installation portion 202 generates the force of wrapping temperature sensor 1, and then firmly fixes temperature sensor 1.The temperature sensor 1 of the present application is fixed on the metal piece to be detected temperature by the above-mentioned temperature sensor fixing 2, and the sensitivity of temperature sensor 1 to the temperature detection of metal piece is improved.When the metal piece is the upper cover 4 of compressor, temperature sensor 1 is fixed by the above-mentioned mode, and the temperature change of compressor can be more sensitive, the protection of compressor is improved, and it is beneficial to the more stable operation of compressor.

[0035] Preferably, asFigures 1-4 As shown in the drawings, the first end of the mounting portion 202 is fixedly connected with the connecting portion 201, the second end of the mounting portion 202 is a threaded segment 205, the outer periphery of the threaded segment 205 is provided with a tapered thread, one end of the tapered thread close to the second end is a small end, one end of the tapered thread close to the first end is a large end, and the threaded segment 205 is provided with a first nut 301.

[0036] The thread of the threaded segment 205 is a tapered thread, when the first nut 301 is arranged on the tapered thread, the first nut 301 has a tendency to reduce the mounting hole 203 in the process of being screwed, thereby increasing the wrapping force on the temperature sensor 1; further improving the stability of the fixation of the temperature sensor 1, avoiding the temperature sensor 1 from being loosened and separated due to the vibration of the metal part.

[0037] Preferably, as shown in the drawings, Figures 1-4 As shown in the drawings, the mounting portion 202 is provided with a stop portion 206, and the end face of the first nut 301 towards the first end is in contact with the stop portion 206.

[0038] The stop portion 206 limits the first nut 301, preventing the first nut 301 from extruding the threaded segment 205 too tightly, which causes the temperature sensor 1 in the mounting hole 203 to be damaged. Further, the stop portion 206 is a baffle.

[0039] Preferably, as shown in the drawings, Figures 1-4 As shown in the drawings, the connecting portion 201 is provided with a connecting face towards the metal part, and the connecting face is provided with a welding spot 207.

[0040] The temperature sensor fixing part 2 is welded on the metal part through the welding spot 207 on the connecting portion 201, and the welding connection is relatively firm and reliable.

[0041] Preferably, as shown in the drawings, Figure 1 As shown in the drawings, the length direction of the temperature sensor 1 is consistent with the depth direction of the mounting hole 203, and the depth L1 of the mounting hole 203 is less than the length L2 of the temperature sensor 1.

[0042] When the temperature sensor 1 is inserted into the mounting hole 203, part of the temperature sensor 1 still leaks out of the mounting portion 202, which is beneficial to the more balanced wrapping force of the mounting portion 202 on the temperature sensor 1.

[0043] Preferably, as shown in the drawings, Figure 3 As shown in the drawings, the mounting hole 203 is a circular hole, and the thickness between the outer periphery of the mounting portion 202 and the inner wall of the mounting hole 203 is t, 2mm≤t≤5mm.

[0044] When t>5mm, the sidewall thickness of the mounting portion 202 is too large, which is not conducive to the deformation of the mounting portion 202 to generate a squeezing force on the temperature sensor 1. When t<2mm, the sidewall thickness of the mounting portion 202 is too small, and the squeezing force of the mounting portion 202 on the temperature sensor 1 is insufficient. When 2mm≤t≤5mm, the mounting portion 202 can provide a more appropriate squeezing force on the temperature sensor 1.

[0045] Further, such as Figure 2 As shown, in the circumferential direction of the mounting hole 203 , the size of the expansion gap is L3, L3≤2mm, to avoid insufficient extrusion force caused by an excessively large expansion gap.

[0046] The utility model provides a compressor, comprising a temperature sensor 1 and the temperature sensor fixing member 2 , wherein the temperature sensor 1 is fixed in the mounting hole 203 .

[0047] The temperature sensor 1 is fixed in the mounting hole 203 of the mounting portion 202 , so that the temperature sensor 1 can be fixed more stably, thereby improving the stability of the fixing of the temperature sensor 1 .

[0048] The “up and down” in this application refers to the “up and down” positions with reference to the spatial orientation of the compressor when it is working normally.

[0049] Preferably, the compressor includes a shell, and the metal part is the upper cover 4 of the shell. When a welding point 207 is provided on the connecting surface, the connecting part 201 is welded to the upper cover 4 through the welding point 207, and the sensing end of the temperature sensor 1 is inserted into the mounting hole 203 and abuts against the upper cover 4.

[0050] The high-temperature, high-pressure refrigerant generated by the compressor flows out of the pump body and into the high-pressure chamber, where it directly contacts the compressor's upper cover 4. This makes measuring the temperature of the compressor's upper cover 4 more accurate than measuring the refrigerant temperature in the exhaust pipe. Connecting portion 201 is secured to upper cover 4 via welds 207. This welded connection improves the stability of the connection between connecting portion 201 and upper cover 4. Temperature sensor 1 is installed by directly inserting it into mounting hole 203, making installation easier.

[0051] Furthermore, a recessed portion is provided on the outer surface of the upper cover 4, and the thickness of the upper cover 4 in the recessed portion is smaller than the thickness at other positions of the upper cover 4. The mounting hole 203 corresponds to the recessed portion, and the sensing end of the temperature sensor 1 is inserted into the recessed portion. In this way, the refrigerant in the outer shell can transfer heat to the temperature sensor 1 through the recessed portion more quickly, that is, the temperature sensor 1 can detect the temperature of the refrigerant faster and more sensitively.

[0052] The upper cover 4 refers to the upper cover of the compressor shell when the compressor is working normally.

[0053] Preferably, as Figure 1 As shown in the drawings, the upper cover 4 is provided with a terminal post 501 and a box cover 502, and the box cover 502 covers the temperature sensor 1 and the terminal post 501.

[0054] By covering the temperature sensor 1 and the terminal post 501 with the box cover 502, the safety of the temperature sensor 1 and the terminal post 501 is improved, the terminal post 501 and the temperature sensor 1 are prevented from being affected by the external environment (water, oil, dust, etc.), the stability of the terminal post 501 is improved, and the sensitivity and stability of the temperature sensor 1 in detecting temperature are improved. Since the temperature of the compressor body can be directly measured, and the high-temperature and high-pressure refrigerant directly acts on the upper cover 4, more accurate and sensitive temperature measurement of the refrigerant is realized, which is conducive to ensuring that the compressor works more stably, avoids safety problems caused by excessively high temperature, and greatly reduces the safety hazards of the compressor.

[0055] Further, the upper cover 4 is fixed with a screw rod 504, the length direction of the screw rod 504 is vertically upward, the screw rod 504 penetrates the box cover 502, and a second nut 302 is arranged on the screw rod 504, and the box cover 502 is fixed on the upper cover 4 through the second nut 302.

[0056] Further, an insulating pad 503 is arranged between the box cover 502 and the upper cover 4, as Figure 7 and Figure 8 As shown in the drawings, the insulating pad 503 is provided with three clearance holes, one for the terminal post 501, one for the temperature sensor fixing part 2, and one for the screw rod 504 fixed on the upper cover 4, and one for the screw rod 504. Among them, the insulating pad 503 includes an insulating part around the screw rod 504, so as to avoid the electrical connection between the wire in the box cover 502 and the screw rod 504.

[0057] Further, as Figure 5 and Figure 6 As shown in the drawings, the inner cavity of the box cover 502 can include two cavities, one for accommodating the terminal post 501 and the other for accommodating the temperature sensor 1, and the screw rod 504 is arranged between the two cavities.

[0058] Further, the box cover 502 is provided with a wire outlet hole 505, and the wires on the terminal post 501 and the wires on the temperature sensor 1 are all discharged from the wire outlet hole 505.
