Description

TECHNICAL FIELD

[0001] The utility model relates to the field of air conditioners, in particular to a heat-sensitive support, a compressor and an air conditioner. BACKGROUND

[0002] At present, the industry usually adopts temperature sensing bags to monitor the temperature of the bend of the exhaust pipe of the compressor, which is used as an important reference index of the overall temperature state of the compressor. However, this traditional method of monitoring the temperature of the bend of the exhaust pipe based on the temperature sensing bag has exposed some defects that cannot be ignored in actual application.

[0003] On the one hand, the temperature of the bend of the exhaust pipe is often much lower than the actual temperature of the motor, and only relying on the temperature of the bend to evaluate the overall temperature state of the compressor may lead to misjudgment of the actual temperature of the motor. On the other hand, the temperature monitored by the temperature sensing bag is easily disturbed by external environmental factors, such as changes in the temperature of the surrounding air and the influence of air flow, which may cause deviations in the temperature data measured by the temperature sensing bag, thereby failing to accurately reflect the real temperature situation inside the compressor.

[0004] Therefore, how to improve the existing compressor temperature monitoring method and improve the accuracy and reliability of temperature monitoring has become an important problem to be solved in the current compressor technology field. SUMMARY

[0005] One purpose of the utility model is to overcome at least one defect in the prior art and provide a heat-sensitive support, a compressor and an air conditioner.

[0006] A further purpose of the utility model is to abut the thermistor against the upper surface of the compressor top cover, thereby improving the reliability of compressor temperature detection.

[0007] Another further purpose of the utility model is to limit the free movement of the thermistor in the slot and prevent the thermistor from accidentally falling out of the slot.

[0008] In particular, according to the first aspect of the utility model, the utility model provides a heat-sensitive support for fixing a thermistor to a compressor top cover, comprising:

[0009] a shell that is buckled on the compressor top cover and defines a slot for accommodating the thermistor between the compressor top cover and the shell; and

[0010] The two side inner walls of the shell are respectively formed with protrusions protruding inward, which are used to extrude the thermistor downward during the insertion of the thermistor, so that the thermistor is abutted against the upper surface of the compressor top cover.

[0011] Optionally, the shell comprises:

[0012] a top plate, arranged in a spaced-apart manner above or below the compressor top cover;

[0013] two first side plates, extending downwardly and gradually away from each other from two sides of the top plate; and

[0014] two second side plates, respectively extending downwardly and vertically from lower ends of the corresponding first side plates;

[0015] The top plate, the two first side plates and the two second side plates together enclose the insertion slot with the compressor top cover.

[0016] Optionally, the protrusions are a plurality of protruding points arranged in a spaced-apart manner along the length direction of the shell; or

[0017] The protrusions are protruding strips extending along the length direction of the shell.

[0018] Optionally, the outer side of the first side plate is provided with a plurality of stamping points, and each of the stamping points correspondingly forms the protruding point on the inner side of the first side plate.

[0019] Optionally, the outer side of the first side plate is provided with a stamping groove, and the stamping groove forms the protruding strip on the inner side of the first side plate.

[0020] Optionally, the shell further comprises:

[0021] two bottom plates, respectively extending horizontally from lower ends of the corresponding second side plates away from the other second side plate, for fixed connection with the compressor top cover.

[0022] Optionally, one end of the shell is formed with an insertion opening for the thermistor to be inserted into the insertion slot, and the other end of the shell is formed with a stop plate for stopping the thermistor; and

[0023] The stop plate extends gradually downwardly from the top plate in the insertion direction of the thermistor.

[0024] Optionally, one end of the first side plate away from the insertion opening is formed with a pressing plate bent inwardly into the insertion slot, and the pressing plate is used for elastically extruding the thermistor so that the thermistor is tightly pressed against the compressor top cover.

[0025] According to a second aspect of the present application, the present application provides a compressor, comprising a compressor top cover, a thermistor and any one of the thermistor supports described above.

[0026] According to a third aspect of the present application, the present application provides an air conditioner, comprising the compressor described above.

[0027] This utility model relates to a thermistor bracket, whose outer shell fastens to the compressor top cover, defining a slot between the thermistor and the compressor top cover to accommodate a thermistor, ensuring a stable mounting position for the thermistor. The inner walls on both sides of the outer shell have inwardly protruding protrusions. These protrusions press the thermistor downwards during insertion, ensuring it presses firmly against the upper surface of the compressor top cover and guaranteeing good contact between the thermistor and the compressor top cover. In this way, the thermistor can more accurately sense temperature changes inside the compressor, improving the accuracy of temperature detection.

[0028] Furthermore, the baffle of this utility model's thermistor bracket not only ensures easier insertion of the thermistor but also prevents it from coming out from the end furthest from the socket. The pressure plate causes the insertion end of the thermistor to be elastically squeezed inward after insertion into the slot, effectively limiting the movement space of the thermistor within the slot. In particular, it ensures good contact between the insertion end of the thermistor and the compressor top cover, significantly enhancing the fixing stability of the thermistor.

The various embodiments provided are intended to explain the present invention and not to limit it. In fact, various modifications and variations to the present invention will be apparent to those skilled in the art without departing from the scope or spirit of the invention. For example, a feature illustrated or described as part of one embodiment may be used with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover such modifications and variations within the scope of the appended claims and their equivalents.

[0046] The following reference Figures 1 to 12This invention describes a thermally sensitive bracket, compressor, and air conditioner according to embodiments of the present invention.

When a feature "includes or contains" one or more of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may be further included.

[0048] In the description of this embodiment, the terms "one embodiment," "some embodiments," "some examples," "one example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] This utility model embodiment first provides a thermistor bracket 10, which is mainly used to fix the thermistor 20 to the compressor top cover 30.

[0050] Traditional monitoring methods typically focus on the bend in the compressor's exhaust pipe, while this invention enables direct monitoring of the compressor's top cover 30. Compared to traditional monitoring methods, this approach offers faster temperature response, higher temperature measurement accuracy, and stronger anti-interference capabilities. This allows for a more precise and stable reflection of the compressor's actual operating temperature, preventing electrical safety accidents caused by inaccurate compressor temperature measurement and improving the compressor's safety factor.

[0051] Figure 1 This is a schematic layout diagram of the installation position of the thermal support 10 according to an embodiment of the present invention. Figure 2 This is a schematic structural diagram of a thermal support 10 according to an embodiment of the present invention.

[0052] like Figure 1 and Figure 2As shown, the thermistor bracket 10 generally includes a housing 100, which is fastened to the compressor top cover 30, defining a slot 101 for receiving the thermistor 20 between the housing 100 and the compressor top cover 30. Furthermore, inwardly protruding protrusions 200 are formed on the inner walls of both sides of the housing 100. These protrusions 200 are used to press the thermistor 20 downwards during insertion, thereby pressing the thermistor 20 against the upper surface of the compressor top cover 30.

[0053] With the above structure, the outer casing 100 is fastened to the compressor top cover 30, defining a slot 101 between the casing 100 and the compressor top cover 30 to accommodate the thermistor 20, ensuring a stable mounting position for the thermistor 20. The inner walls on both sides of the outer casing 100 have inwardly protruding protrusions 200. These protrusions 200 press the thermistor 20 downwards during insertion, pressing it firmly against the upper surface of the compressor top cover 30, ensuring good contact between the thermistor 20 and the compressor top cover 30. Thus, the thermistor 20 can more accurately sense temperature changes inside the compressor, improving the accuracy of temperature detection.

[0054] In one optional embodiment, the housing 100 includes a top plate 110, two first side plates 120, and two second side plates 130. The top plate 110 and the compressor top cover 30 are arranged vertically at a distance. The two first side plates 120 extend downward at an angle from both sides of the top plate 110 and gradually move away from each other. The two second side plates 130 extend vertically downward from the lower ends of their respective first side plates 120. The top plate 110, the two first side plates 120, and the two second side plates 130, together with the compressor top cover 30, enclose a slot 101.

[0055] Thus, when the thermistor 20 is inserted into the slot 101, its position is defined and secured by the top plate 110, the two first side plates 120, the two second side plates 130, and the compressor top cover 30.

[0056] In an optional embodiment, the housing 100 further includes two base plates 140, which extend horizontally from the lower end of the corresponding second side plate 130 in a direction away from the other second side plate 130, for fixed connection with the compressor top cover 30.

[0057] In some alternative embodiments, the top plate 110, the first side plate 120, the second side plate 130 and the bottom plate 140 of the outer casing 100 are integrally formed. The bottom plate 140 is provided with a plurality of welding points 141, and the bottom plate 140 is welded and fixed to the compressor top cover 30 through the welding points 141.

[0058] In this embodiment, the thermistor 20 is cylindrical and is horizontally installed in the slot 101 of the thermistor bracket 10, making linear contact with the compressor top cover 30 to monitor the temperature.

[0059] To improve the accuracy of temperature detection, a wide horizontal surface is selected in the area of ​​the compressor top cover 30 used to install the thermistor bracket 10 to ensure full contact between the thermistor 20 and the compressor top cover 30.

[0060] In an alternative embodiment, the protrusions 200 are a plurality of protrusions spaced apart along the length of the housing 100. These protrusions may be spherical, ellipsoidal, or other shapes.

[0061] Preferably, the bump is spherical. Due to its smooth surface, the spherical bump can effectively prevent the thermistor 20 from being scratched during disassembly and assembly.

[0062] In some embodiments, a plurality of stamping points 201 are provided on the outer side of the first side plate 120, and each stamping point 201 is correspondingly formed as a protrusion on the inner side of the first side plate 120.

[0063] In the actual manufacturing process, the mold can be used to apply pressure inward from the outer side of the first side plate 120 to cause plastic deformation, thereby forming the stamping point 201. Since the first side plate 120 has a certain thickness, the inner side of the first side plate 120 will also be squeezed and deformed during the stamping process, thereby forming the protrusion 200 corresponding to the outer stamping point 201.

[0064] The formation process of the stamping point 201 also enhances the structural strength of the first side plate 120, making it more durable. Because the protrusion is formed using a stamping process, it is tightly bonded to the first side plate 120, exhibiting high wear resistance and maintaining its shape and dimensional stability over a long period.

[0065] In another alternative embodiment, the protrusion 200 is a ridge extending along the length of the housing 100. The ridge can be a cylindrical ridge, a prism ridge, or other forms of polyhedral ridge.

[0066] Preferably, the protrusion is a cylindrical protrusion, which also has the characteristic of a smooth surface, effectively preventing the thermistor 20 from being scratched during disassembly and assembly.

[0067] In some embodiments, a stamping groove 202 is provided on the outer side of the first side plate 120, and the stamping groove 202 forms a protrusion on the inner side of the first side plate 120.

[0068] like Figures 11 to 12 As shown, unlike discrete bumps, the ridges provide continuous pressure for the thermistor 20, making the thermistor 20 more securely fixed in the slot 101 and reducing the risk of displacement due to vibration or impact.

[0069] The raised strip design allows the pressure on the thermistor 20 to be distributed more evenly on its surface when it is squeezed, avoiding deformation or damage caused by excessive local pressure.

[0070] In addition, the design of the stamping groove 202 makes the formation of the convex strip easier, which can be completed in just one stamping operation, simplifying the processing flow and improving production efficiency.

[0071] In an optional embodiment, one end of the housing 100 is formed with a socket for inserting the thermistor 20 into the slot 101, and the other end of the housing 100 is formed with a baffle 150 to stop the thermistor 20. The baffle 150 extends gradually downward from the top plate 110 along the insertion direction of the thermistor 20.

[0072] Typically, the socket is formed on the front side of the housing 100, and the baffle 150 is formed on the rear side of the housing 100. The thermistor 20 is inserted into the slot 101 from front to back. The design of the socket and the baffle 150 provides clear directional guidance for the insertion of the thermistor 20, making the installation process simpler and faster. The presence of the baffle 150 ensures that the thermistor 20 is effectively stopped after being inserted into the predetermined position, preventing over-insertion or under-insertion, thereby ensuring the precise positioning of the thermistor 20 in the slot 101.

[0073] In an alternative embodiment, the end of the first side plate 120 away from the socket is formed with a pressure plate 160 that bends inward toward the slot 101. The pressure plate 160 is used to elastically compress the thermistor 20, so that the thermistor 20 is pressed against the compressor top cover 30.

[0074] The pressure plate 160 causes the insertion end of the thermistor 20 to be subjected to inward elastic compression after it is inserted into the slot 101, which effectively restricts the movement space of the thermistor 20 in the slot 101. In particular, it ensures good contact between the insertion end of the thermistor 20 and the compressor top cover 30. This close contact not only improves the heat transfer efficiency, but also significantly enhances the fixed stability of the thermistor 20.

Figure 5 yes Figure 2 A schematic front view of the thermal support 10. Figure 6 yes Figure 5 Schematic sectional view along the BB direction. Figure 7 This is a schematic structural diagram of a thermistor 20 according to an embodiment of the present invention. Figure 8 This is a schematic assembly diagram of the thermistor 20 and the thermistor bracket 10 according to one embodiment of the present invention.Figure 9 yes Figure 8 A schematic cross-sectional view, Figure 10 yes Figure 9 A schematic cross-sectional view along the CC direction.

[0076] like Figures 3 to 10 As shown, in a specific example, I can make the following detailed settings for the dimensions and angle parameters of the thermal support 10 and its associated components:

[0077] First, the basic structural parameters of the outer shell 100 include: the thickness of the top plate 110, the first side plate 120, the second side plate 130 and the bottom plate 140 of the outer shell 100 is T, where 0.1≤T≤5mm, preferably, T is 0.5mm~2mm, the total height of the outer shell 100 is H, the total width is L, the width of the slot 101 is L1, the length of the first side plate 120 is L2, the length of the bottom plate 140 is L3, and the total length of the outer shell 100 is L4.

[0078] Next, the parameters of the stamping point 201 and the convex point include: the radius of the stamping point 201 is R1, the radius of the convex point is R2, the included angle formed by the center lines of any two left and right symmetrical convex points is α, where 0°≤α≤180°, and L6 is the vertical distance between the center of the convex point and the central axis of the thermistor 20.

[0079] Secondly, the parameters of the pressure plate 160 and the baffle 150 include:

[0080] The included angle between the pressure plate 160 and the first side plate 120 connected to it is β. After assembly, the pressure plate 160 is pushed upward by the thermistor 20, and β increases to β1, satisfying 90°≤β(β1)≤180°. The included angle between the baffle 150 and the top plate 110 connected to it is γ, satisfying 90°≤γ≤150°.

[0081] Furthermore, the assembly relationship between the thermistor 20 and the thermistor bracket 10 is as follows:

[0082] The thermistor 20 has a diameter of φB and a length of L5, where L6 - R2 = (1 / 2)φB. This ensures the proper positioning of the thermistor 20 during assembly. The total length L4 of the housing 100, the length L5 of the thermistor 20, and the length L3 of the base plate 140 satisfy L4 ≥ L5 ≥ L3, and the difference between L5 and L3 does not exceed 5mm, i.e., L5 - L3 ≤ 5mm.

[0083] Finally, regarding the assembly conditions of thermistor 20:

[0084] Considering the assembly of the thermistor 20, the following condition should be met: T+H1≥(1 / 2)φB. This ensures that the sum of the height of the third side plate and the thickness of the base plate 140 is greater than or equal to the radius of the thermistor 20, so as to ensure that the thermistor 20 can be correctly assembled and work stably.

[0085] The thermal bracket 10 in this embodiment facilitates the installation and removal of the thermistor 20. The thermal bracket 10 ensures that the thermistor 20 remains attached to the housing 100 during actual operation, and allows for immediate monitoring of the compressor's exhaust temperature. This improves the accuracy of compressor temperature measurement and control, enhances the reliability of related test data, avoids electrical safety accidents caused by inaccurate compressor temperature measurement, and increases the compressor's safety factor.

[0086] This utility model embodiment also provides a compressor, which may include a compressor top cover 30, a thermistor 20, and a thermistor bracket 10 of any of the above embodiments.

[0087] The compressor using the aforementioned thermistor bracket 10 can achieve a more stable installation of the thermistor 20, effectively improving the accuracy and reliability of temperature detection, while reducing the risk of performance degradation due to improper installation or external environmental factors.

[0088] In addition, a cover 310 is provided on the top cover 30 of the compressor. When selecting the installation position of the thermal bracket 10, it is necessary to ensure that the cover 310 will not interfere with the thermal bracket 10 after assembly.

[0089] This utility model embodiment also provides an air conditioner, which includes the compressor described above.

[0090] The compressor can adjust its operating frequency according to the indoor temperature. When the indoor temperature is high, the compressor can run at a higher frequency to lower the indoor temperature. The thermistor 20 is pressed against the compressor top cover 30 to detect the compressor's exhaust temperature in real time, thereby controlling the compressor's operating frequency based on the exhaust temperature to protect the compressor.

[0091] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
