Description

Technical Field

[0002] With the development of science and technology, refrigeration equipment such as air conditioners and refrigerators are widely used in daily life. The compressor, as the power unit of the refrigeration system, drives the refrigerant to circulate and exchange heat in the pipeline, thereby meeting the needs of cooling or heating. However, prolonged use of the refrigeration system under high load can cause the compressor motor temperature to become too high and trigger a series of effects such as demagnetization, leading to a decrease in compressor cooling capacity and refrigeration equipment malfunction.

[0003] Currently, existing technologies typically employ external temperature sensors to detect the real-time operating temperature of the compressor and control the rotary compressor based on the detected temperature, providing effective protection. These external temperature sensors are mounted to the compressor using a mounting bracket. However, this bracket, which clamps the temperature sensor between itself and the compressor using spring clips, cannot reliably guarantee the stability of the connection between the temperature sensor and the compressor. Significant vibrations during compressor operation can cause the temperature sensor to shift or even fall off, leading to inaccurate or no temperature readings. This, in turn, prevents the compressor from operating normally and stably, and may even cause it to burn out. Utility Model Content

[0061] In the prior art, the external temperature sensing module is usually installed on the discharge pipe of the compressor, but it is still a certain distance from the compressor body, and it detects the temperature of the compressor discharge pipe in real time, while the temperature of the compressor discharge pipe decays relative to the temperature of the compressor body, which will cause a lag phenomenon in the control and protection of the compressor, and in severe cases, it can even cause the compressor to burn out. Moreover, since the temperature sensing module is far away from the compressor body, there can be other heat sources in the environment where the compressor is located, which will interfere with the detection of the temperature of the compressor body by the temperature sensing module.

[0062] With reference to Figure 1 and Figure 2 In the present embodiment, the compressor includes a temperature sensing element fixing bracket 100, and a casing upper cover 710.

Further, the temperature sensing element fixing support 100 can stably fix the temperature sensing element 800 on the compressor. Therefore, the temperature sensing element fixing support 100 can improve the stability of the temperature sensing element 800 installed on the compressor, ensure that the compressor can stably operate, and effectively limit the occurrence of the compressor burning out.

[0077] It can be understood that the temperature sensing element fixing support 100 of the embodiment sets the range of the height of the fixing structure 400 protruding into the cover cavity 310 to be greater than or equal to 0.05 mm and less than or equal to 2 mm, which can ensure that the fixing structure 400 can limit the temperature sensing element 800 installed in the cover cavity 310, while avoiding damage to the temperature sensing element 800 by the fixing structure 400 during the process of installing the temperature sensing element 800 into the cover cavity 310.

And the cover shell 300 will leave a stamping groove 500 on the outer side surface after stamping. Further, the depth of the stamping groove 500 can be equal to the height of the fixing structure 400 protruding into the cover cavity 310, so as to ensure the manufacturing precision of the fixing structure 400 during the production of the temperature sensing element fixing bracket 100, ensure the limiting effect of the fixing structure 400 on the temperature sensing element 800, and ensure the performance of the temperature sensing element fixing bracket 100.

[0101] It can be understood that, by arranging the limiting structure 600, the temperature sensing element 800 can be limited from being taken out of the cover cavity 310 from the limiting opening 312, and thus the temperature sensing element fixing support 100 of the embodiment can further improve the stability of the installation of the temperature sensing element 800 on the compressor. Moreover, compared with the limiting opening 312 being a completely closed wall of the cover cavity 310, the embodiment can reduce the overall weight of the temperature sensing element fixing support 100 by arranging the limiting opening 312 and the limiting structure 600, so as to make the temperature sensing element fixing support 100 lightweight and reduce the production cost of the temperature sensing element fixing support 100.

Therefore, the fixing structure 400 can be arranged only on the surrounding side plate 320, and not arranged on the first connecting plate 330 and the second connecting plate 340, so as to ensure the limiting effect of the fixing structure 400 on the temperature sensing element 800, avoid the use of materials / unnecessary processes, ensure the performance of the temperature sensing element fixing support 100, and ensure that the temperature sensing element fixing support 100 can have a lower production cost.

[0108] In an alternative embodiment of the limiting structure 600, the limiting structure 600 can be a plurality of limiting plates connected to the cover 300 and arranged at the limiting opening 312, and the plurality of limiting plates can be arranged along the circumference of the limiting opening 312, so that the limiting structure 600 covers the limiting opening 312.

[0109] Referring to Figure 4 In this embodiment, the width E of the first limiting plate 610 and the second limiting plate 620 in the length direction of the cover 300 can be greater than or equal to 0.2 mm and less than or equal to 15 mm.

[0110] It can be understood that the width E of the first limiting plate 610 and the second limiting plate 620 in the length direction of the cover 300 can be greater than or equal to 0.2 mm and less than or equal to 15 mm, so that the limiting effect of the temperature sensing element 800 can be ensured, and the temperature sensing element 800 can be prevented from being pulled out of the cover cavity 310 from the limiting opening 312.

[0111] Referring to Figure 4 In this embodiment, the width E of the first limiting plate 610 and the second limiting plate 620 in the length direction of the cover 300 can be greater than or equal to 0.5 mm and less than or equal to 10 mm.

[0112] It can be understood that the width E of the first limiting plate 610 and the second limiting plate 620 in the length direction of the cover 300 can be greater than or equal to 0.5 mm and less than or equal to 10 mm. For example, the width of the first limiting plate 610 and the second limiting plate 620 in the length direction of the cover 300 can be 0.5 mm, 2 mm, 4 mm, 6 mm, 8 mm, and 10 mm, so that the limiting effect of the temperature sensing element 800 can be ensured, the temperature sensing element 800 can be prevented from being pulled out of the cover cavity 310 from the limiting opening 312, and the compactness of the temperature sensing element fixing bracket 100 can be ensured.

[0113] Referring to Figure 5In the embodiment, the thickness F of the first limiting plate 610 and the second limiting plate 620 is greater than or equal to 1 mm and less than or equal to 2 mm, so as to ensure the limiting effect on the temperature sensing element 800.

[0114] With reference to Figure 5 and Figure 8 In the embodiment, the first limiting plate 610 and the second limiting plate 620 respectively coincide with the projection of the temperature sensing element 800 in the length direction of the shell 300.

[0115] It should be understood that the length of the extension of the first limiting plate 610 and the second limiting plate 620 to the limiting opening 312 should ensure the limiting effect on the temperature sensing element 800, that is, the first limiting plate 610 and the second limiting plate 620 respectively coincide with the projection of the temperature sensing element 800 in the length direction of the shell 300, or the distance G between the first limiting plate 610 and the second limiting plate 620 is less than or equal to the overlapping distance H of the temperature sensing element 800 and the limiting structure 600. Moreover, the calculation method of the overlapping distance of the temperature sensing element 800 and the limiting structure 600 can be calculated by the following formula:

[0116]

[0117] Wherein, T is the thickness of the base 200, and L is the diameter of the temperature sensing element 800.

[0118] Therefore, the above setting can avoid the situation that the length of the extension of the first limiting plate 610 and the second limiting plate 620 to the limiting opening 312 is too short to play a limiting effect on the temperature sensing element 800, so that the temperature sensing element 800 is out of the shell cavity 310 from the limiting opening 312.

[0119] It should also be understood that the first limiting plate 610, the second limiting plate 620, the first mounting plate 210 and the second mounting plate 220 are arranged on the same surface, and the first limiting plate 610 and the second limiting plate 620 are arranged at the two ends of the shell 300 close to the compressor / the parts of the limiting opening 312 close to the compressor (i.e. the first limiting plate 610 and the second limiting plate 620 are arranged at the bottom end of the limiting opening 312 / the shell 300 in the figure). Therefore, the distance G between the first limiting plate 610 and the second limiting plate 620 can be set to be less than or equal to 0.5 mm, so as to ensure that the first limiting plate 610 and the second limiting plate 620 can play a limiting effect on the temperature sensing element 800.

[0120] With reference to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7In the present embodiment, the first limiting plate 610, the second limiting plate 620, the first mounting plate 210 and the second mounting plate 220 are all arranged parallel to the target mounting surface 720, and are on the same plane.

[0121] It should be understood that the arrangement of the first limiting plate 610, the second limiting plate 620, the first mounting plate 210 and the second mounting plate 220 parallel to the target mounting surface 720 can ensure the stability of the mounting of the temperature sensing element fixing bracket 100 and the temperature sensing element 800 to the compressor. Moreover, the arrangement of the first limiting plate 610, the second limiting plate 620, the first mounting plate 210 and the second mounting plate 220 on the same plane can reduce the complexity of the production process of the temperature sensing element fixing bracket 100, i.e., the base 200, the first limiting plate 610 and the second limiting plate 620 can be punched from one plate piece. Moreover, there is no need to further bend the first limiting plate 610 and the second limiting plate 620 (in order to shield the limiting structure 600 at the limiting opening 312) and other processes, thereby reducing the production cost of the temperature sensing element fixing bracket 100.

[0122] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 , in the present embodiment, the mounting surface can be, for example, the plane of the outer top surface of the compressor shell upper cover 710, in which case the first limiting plate 610, the second limiting plate 620, the first mounting plate 210 and the second mounting plate 220 can all be flat plates.

[0123] In some other embodiments, the mounting surface can be, for example, the curved surface of the compressor shell side wall, in which case the first limiting plate 610, the second limiting plate 620, the first mounting plate 210 and the second mounting plate 220 can all be curved plate bodies.

[0124] Referring to Figure 5 and Figure 8 , in the present embodiment, the cross section of the surrounding side plate 320 has a semi-arc structure; and the inner diameter R of the semi-arc structure is equal to the depth I of the cover cavity 310 (or the inner radius r of the semi-arc structure is equal to the sum of the thickness T of the base 200 and the height K of the first connecting plate 330 away from the mounting surface / compressor).

[0125] It can be understood that the inner diameter R of the semi-arc structure is set to be equal to the depth I of the cover cavity 310 to ensure the regularity of the cover cavity 310. Further, after the temperature sensing element 800 is installed into the cover cavity 310, the area of the contact between the temperature sensing element 800 and the surrounding side plate 320 can be the largest, and therefore, setting the inner diameter R of the semi-arc structure to be equal to the depth I of the cover cavity 310 can further ensure the stability of the fixing bracket in setting the temperature sensing element 800 on the compressor.

[0126] With reference to Figure 5 , Figure 8 and Figure 9 In the present embodiment, the depth I of the cover cavity 310 can be greater than or equal to the diameter L of the cylindrical temperature sensing element 800 to ensure that the temperature sensing element 800 can be installed into the cover cavity 310.

[0127] With reference to Figure 5 In the present embodiment, the height M of the temperature sensing element fixing bracket 100 in the direction away from the mounting surface / compressor can be equal to the sum of twice the thickness T of the base 200, the height K of the first connecting plate 330 in the direction away from the mounting surface / compressor, and the inner radius r of the semi-arc structure.

[0128] In the present embodiment, the cross section of the surrounding side plate 320 can also be a semi-rectangular structure, a semi-polygonal structure, which can be designed and produced according to the specific shape of the temperature sensing element 800.

[0129] With reference to Figure 5 In the present embodiment, the thickness N of the cover shell 300 and the thickness T of the base 200 are both greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0130] It can be understood that the thickness of the cover shell 300 and the base 200 are both greater than or equal to 0.5 mm and less than or equal to 5 mm to ensure the stability of the temperature sensing element fixing bracket 100 in fixing the temperature sensing element 800 on the compressor.

[0131] With reference to Figure 5 In the present embodiment, the thickness N of the cover shell 300 and the thickness T of the base 200 are both greater than or equal to 1 mm and less than or equal to 2 mm.

[0132] It can be understood that the thickness of the cover shell 300 and the base 200 can be 1 mm, 1.2 mm, 1.4 mm, 1.8 mm, 2 mm, which can further ensure the stability of the temperature sensing element fixing bracket 100 in fixing the temperature sensing element 800 on the compressor, while effectively ensuring the compactness of the temperature sensing element fixing bracket 100, and ensuring that the temperature sensing element fixing bracket 100 can have a lower production cost.

[0133] With reference to Figure 4 and Figure 9In the embodiment, the length P of the cover 300 can be less than the length Q of the temperature sensing element 800, and the difference between the length of the cover 300 and the length of the temperature sensing element 800 is less than or equal to 10 mm.

[0134] It can be understood that the length of the cover 300 can be set to be less than the length of the temperature sensing element 800, and the difference between the length of the cover 300 and the length of the temperature sensing element 800 is less than or equal to 10 mm, so as to ensure the stability of the temperature sensing element fixing support 100 in fixing the temperature sensing element 800 on the compressor, and ensure the compactness of the temperature sensing element fixing support 100.

[0135] Referring to Figure 4 and Figure 9 In the embodiment, the length P of the cover 300 can be less than the length Q of the temperature sensing element 800, and the difference between the length of the cover 300 and the length of the temperature sensing element 800 is less than or equal to 5 mm.

[0136] It can be understood that the difference between the length of the cover 300 and the length of the temperature sensing element 800 can be set to 1 mm, 2 mm, 3 mm, 4 mm and 5 mm, so as to further ensure the stability of the temperature sensing element fixing support 100 in fixing the temperature sensing element 800 on the compressor, and ensure the compactness of the temperature sensing element fixing support 100.

[0137] It should be further pointed out that the length of the cover 300 can be designed according to actual needs without interfering with the wiring end cover 730.

[0138] At this point, those skilled in the art should recognize that although the present application has been shown and described in detail in the above embodiments, many other variations or modifications can be determined or deduced directly according to the disclosure of the present application without departing from the spirit and scope of the present application.
