Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to a compressor housing component, a compressor, and an air conditioner. Background Art

[0002] The compressor is a key component of an air conditioner, compressing and driving the refrigerant in the refrigerant circuit. The compressor is typically installed inside the air conditioner's outdoor unit, providing the driving force for the refrigerant. The compressor is typically equipped with a temperature sensor, inserted into a sleeve and secured to the compressor exhaust pipe using a tightening band and insulation tubing to detect temperature. This fixed structure of the temperature sensor has low assembly efficiency and cannot meet the requirements of automated assembly on production lines. Furthermore, the detected temperature has a lag. The air conditioner controls the compressor based on the temperature data detected by the temperature sensor, potentially preventing timely protective action, which can lead to compressor failures such as motor demagnetization.

[0003] In order to overcome the above-mentioned shortcomings of the prior art, a temperature sensor fixing bracket assembled on the compressor housing is proposed in the related art, such as Figure 1 As shown, the top surface of the sensor fixing bracket is a planar structure, and a plurality of elastic convex structures extending toward one side of the sensor are arranged at intervals on the planar structure along the direction of sensor insertion, so that the free end of the elastic convex is used to form an elastic resistance force on the outer surface of the sensor, and then the elastic resistance force is used to achieve clamping and fixing of the sensor. In specific applications, the temperature sensor (also called temperature sensing package) is a cylinder, and the free ends of each elastic convex structure on the top surface of the planar structure objectively achieve fixation of the sensor in a single-point contact manner (or a line contact with a very short distance along the sensor insertion direction). When the aforementioned elastic resistance force is small, the continuous vibration of the compressor during operation will cause the sensor to be loosely installed or even fall off. When the aforementioned elastic resistance force is large, the local stress of the sensor is too large due to the small force area, which makes the sensor insertion process difficult on the one hand, and on the other hand, there is a risk of scratching the sensor or even damaging the sensor.

[0010] In some embodiments, each of the elastic clamping convexes is punched on the fixed frame body.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] For the convenience of description, spatial relative terms can be used herein, such as "over", "above", "upper surface", "upper" and the like, to describe the spatial position relationship of one device or feature with other devices or features as shown in the figure. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the figure.

[0035] In addition, it should be noted that the use of "first", "second" and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, and therefore cannot be understood as a limitation on the protection scope of the utility model.

[0036] Referring to Figure 2 and Figure 10As shown, according to the embodiment of the utility model, provide a kind of compressor shell assembly, including compressor shell (not shown in drawing) and the sensor fixing frame 1 of fixed connection on the outer side of the compressor shell, the sensor fixing frame 1 includes fixing frame body 11 and the connecting seat 14 at the both side ends of this fixing frame body 11, the sensor fixing frame 1 is fixedly connected with compressor shell via the connecting seat 14, for example, corresponding welding point 141 is equipped on the bottom surface of connecting seat 14, to facilitate the convenient and reliable welding between connecting seat 14 and compressor shell, temperature sensor (not shown in drawing) has temperature measuring cylinder section, generally speaking, the temperature measuring main body of temperature sensor is a cylinder, the aforementioned temperature measuring cylinder section is at least a part of the cylinder, the fixing frame body 11 has the compression part (not marked in drawing) that can be along the circumferential direction of the temperature measuring cylinder section and the cylindrical surface of the temperature measuring cylinder section forms camber surface contact, the temperature sensor is clamped between the compression part and the compressor shell.

[0037] In the technical solution, the fixing frame body 11 has the compression part that can be along the circumferential direction of the temperature measuring cylinder section and the cylindrical surface of the temperature measuring cylinder section forms camber surface contact, so as to realize the camber surface compression of the outer circumferential wall of the temperature sensor.Compared with the compression mode of point contact or line contact in the prior art, the utility model has larger force application area for the temperature sensor, so that the anti-vibration and anti-falling effect of the temperature sensor is better under the premise of applying the same compression force to the temperature sensor, and the local stress formed on the outer surface of the temperature sensor is not too large, so that the phenomenon of scratching or even damaging the temperature sensor caused by excessive local stress is avoided, thereby effectively preventing the temperature sensor from being inaccurate in temperature measurement or even losing the temperature measurement function due to deformation of the temperature measurement structure.

[0038] In a feasible implementation manner, referring to Figures 2 to 5 As shown, the compression part is the arc-shaped wall surface 111 formed on the side surface of the fixing frame body 11 towards the compressor shell, and the arc-shaped wall surface 111 is in interference fit with the temperature sensor when the temperature sensor is assembled in the sensor fixing frame 1.

[0039] In the technical solution, the compression part is designed as the arc-shaped wall surface 111, and the arc-shaped wall surface 111 is in interference fit with the temperature measuring cylinder section of the temperature sensor, so that the aforementioned camber surface contact can be realized by the shape matching between the arc-shaped wall surface 111 and the temperature measuring cylinder section, and the area of the camber surface contact is large enough, and the anti-vibration and anti-falling effect is higher.

[0040] Specifically, the interference fit between the arc-shaped wall 111 and the temperature sensor has an interference fit of 0.1 mm to 0.5 mm. As shown in the table below, it can be seen from the test data that when the interference fit exceeds 0.5 mm, the interference fit is too large, resulting in difficulty in assembling the temperature sensor and even scratches or crushing. In addition, when the interference fit is less than 0.1 mm, the interference fit is too small, and the clamping force of the fixed frame 11 on the temperature sensor is insufficient, resulting in falling off.

[0041] Number of tests d / mm h / mm Average value of moving resistance / N Number of scratches 10 6 6 0 0 10 6 5.95 10.2 0 10 6 5.9 18.1 0 10 6 5.7 20.5 0 10 6 5.6 23.3 0 10 6 5.5 25.5 0 10 6 5.4 30.7 2 10 6 5.3 37.8 1 10 6 5.2 44.0 3 10 6 5.1 52 5

[0042] The interference can be controlled in a variety of ways. For example, in one embodiment, the maximum clearance height between the arc-shaped wall 111 and the area where the compressor housing faces each other is h, the diameter of the temperature measuring cylindrical section of the temperature sensor is d, and 0.1 mm ≤ dh ≤ 0.5 mm ( Figure 4 As shown), at this time, there is at least partial arc surface contact and fit between the top arc segment of the temperature measuring cylindrical segment and the aforementioned arc wall surface 111, thereby forming a reliable limit and positioning for the temperature sensor, and / or, in another embodiment, the arc wall surface 111 is an arc wall surface concentric with the temperature measuring cylindrical segment, and the diameter of the arc wall surface 111 is D, 0.1mm≤dD≤0.5mm, so that the arc wall surface and the temperature measuring cylindrical segment are concentrically arranged. When the temperature sensor is in the assembled state, the top arc segment of the temperature measuring cylindrical segment and the arc wall surface achieve a larger area of ​​arc surface contact and fit, which has a better centering, limiting and positioning effect on the temperature sensor.

[0043] In another feasible embodiment, see Figures 9 to 10 As shown, the pressing portion is a plurality of elastic clamping protrusions 12 formed on the fixing frame 11 and extending toward the central axis of the temperature measuring cylindrical segment of the temperature sensor. The free ends of the plurality of elastic clamping protrusions 12 are arranged at intervals along the circumferential direction of the temperature measuring cylindrical segment to form an envelope interference with a part of the cylindrical surface of the temperature measuring cylindrical segment, thereby realizing that each elastic clamping protrusion 12 applies a pressing force to the temperature measuring cylindrical segment. The plurality of elastic clamping protrusions 12 are also arranged at intervals along the axial direction of the temperature measuring cylindrical segment to achieve balanced compression of the temperature measuring cylindrical segment in its axial direction. For details, see Figure 9As shown, each elastic clamping protrusion 12 has a fixed end connected with the fixed frame body 11 and a free end used for abutting against the cylindrical surface of the temperature measuring cylindrical segment, wherein the fixed end is located at the side close to the temperature sensor insertion side of the corresponding free end. The abutting against the envelope specifically refers to that the free ends of each elastic clamping protrusion 12 arranged at intervals along the circumferential direction of the same radial plane of the temperature measuring cylindrical segment are all located on a circle concentric with the temperature measuring cylindrical segment in the free state or the state of abutting against the cylindrical surface of the temperature measuring cylindrical segment to apply force, thereby realizing the profiled surrounding of the corresponding circumferential direction of the temperature sensor in the assembled state of the temperature sensor.

[0044] In the technical scheme, multiple elastic clamping protrusions 12 capable of abutting against the envelope of the outer circumferential wall of the temperature measuring cylindrical segment are arranged at the same radial plane of the temperature measuring cylindrical segment, so that the elastic clamping protrusions 12 collectively apply a pressing force to the temperature measuring cylindrical segment, forming intermittent arc surface contact and having a larger pressing contact area, thereby having higher anti-vibration and anti-falling effects.

[0045] As a preferred embodiment, each elastic clamping protrusion 12 is punched on the fixed frame body 11, thereby simplifying the manufacturing difficulty of the elastic clamping protrusion 12. In a specific embodiment, the sensor fixed frame 1 can be formed by bending a metal sheet of a predetermined size, and at this time, the elastic clamping protrusion 12 should be punched on the metal sheet in a flat state, thereby being more convenient to manufacture. Of course, in some embodiments, the sensor fixed frame 1 can also be manufactured by injection molding.

[0046] In some embodiments, the fixed frame body 11 extends along the axial direction of the temperature measuring cylindrical segment, and the top of the fixed frame body 11 has a semicircular fan ring shape, and the two ends of the semicircular fan ring shape are integrally formed with the connecting seat 14 through corresponding connecting segments (not labeled in the figure), and the two connecting segments on the two sides can form an isosceles trapezoid or a rectangle.

[0047] In the technical scheme, the fixed frame body 11 has a semicircular fan ring shape with a uniform thickness, thereby facilitating the bending of a metal sheet with the same thickness or the forming consistency when injection molding.

[0048] In a preferred embodiment, an included angle of not less than 90° is formed between the connecting seat 14 and the connecting segment connected therewith, thereby facilitating the smooth demolding when injection molding.

[0049] For reference Figures 6 to 8As shown, in some embodiments, the fixed frame body 11 has an insertion entrance end and an insertion tail end arranged in sequence along the insertion direction of the temperature sensor, and a notch 13 extending along the axial direction of the temperature measuring cylindrical segment is formed on the insertion tail end, see Figure 8 As shown, the notch 13 extends along the axial direction of the temperature measuring cylindrical segment for a certain length without penetrating through the entire length of the fixed frame body 11, so that the interference deformation amount of the fixed frame body 11 can be increased, the assembly smoothness can be improved, and the uncontrolled cracking of the frame body caused by the uncontrollable compression force during the interference fit deformation process can be effectively prevented. In a preferred embodiment, the notch 13 has two notches, and the two notches are left-right symmetrical about the left-right symmetrical surface of the sensor fixed frame 1.

[0050] In another possible embodiment, the clearance height between the fixed frame body 11 and the compressor shell in the direction from the insertion entrance end to the insertion tail end is gradually reduced, and the clearance height of the insertion entrance end is greater than the diameter of the temperature measuring cylindrical segment, so that the temperature sensor can be smoothly inserted into the fixed frame body 11, and the gradually increasing adjustment of the compression force of the temperature sensor can be realized by using the gradually reduced structure. At this time, the part with a clearance height less than the diameter of the temperature measuring cylindrical segment forms the compression part.

[0051] According to the embodiments of the present application, a compressor is also provided, which comprises the compressor shell assembly described above. At this time, the compressor shell can be a top cover or a compressor side wall, so that the real-time temperature in the shell can be accurately detected.

[0052] According to the embodiments of the present application, an air conditioner is also provided, which comprises the compressor described above.

[0053] It is easy for those skilled in the art to understand that the advantageous technical features of the above-mentioned modes can be freely combined and superimposed without conflict.

[0054] The above description is only the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above description is only the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications shall be regarded as the protection scope of the present application.
