Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor and a refrigeration device. Background Art

[0002] Currently, a compressor includes a housing and a temperature sensing component. The temperature sensing component is mounted on the housing and is capable of detecting the housing temperature. In related art, a bracket for the temperature sensing component is provided on the housing, and the temperature sensing component is fixed to the housing via the bracket, allowing the temperature sensing component to contact the housing and thereby detect the housing temperature. However, due to poor consistency in the position of the temperature sensing component during installation, Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a compressor.

[0005] A second aspect of the present invention provides a refrigeration device.

[0006] In view of this, a first aspect of the present invention provides a compressor comprising a housing, a position-limiting component, and a temperature detection component. The position-limiting component is connected to the housing, and the position-limiting component and the housing enclose a mounting cavity, wherein at least one side of the mounting cavity is provided with a first opening. The position-limiting component includes a positioning portion, the positioning portion being located on a side of the mounting cavity away from the first opening, and the positioning portion protruding from the inner wall of the mounting cavity toward the interior of the mounting cavity. The temperature detection component is inserted into the first opening, extends into the mounting cavity, and abuts against the positioning portion.

[0007] The compressor provided by the present application includes a shell and a limiting component. The limiting component is connected to the shell, and the limiting component is supported by the shell, thereby improving the stability of the limiting component. An installation cavity is set between the limiting component and the shell, and a first opening is set on at least one side of the installation cavity. The compressor also includes a temperature detection component. The temperature detection component is inserted into the installation cavity through the first opening. The limiting component can install and fix the temperature detection component, thereby improving the stability of the temperature detection component. Moreover, since the first opening is set on at least one side of the installation cavity, when installing the temperature detection component, the temperature detection component can be installed by inserting the temperature detection component into the installation cavity through the first opening, thereby simplifying the installation process of the temperature detection component, reducing the difficulty of installing the temperature detection component, and improving the installation efficiency of the temperature detection component.

[0008] The limiting component includes a positioning portion, the positioning portion is located on a side of the installation cavity away from the first opening, the positioning portion protrudes from the inner wall of the installation cavity toward the inside of the installation cavity, and after the temperature detection component is inserted into the installation cavity, it abuts against the positioning portion, and then the temperature detection component is positioned by the positioning portion. Since the limiting component is provided with a positioning portion protruding toward the inside of the installation cavity, the installation positions of the temperature detection components of different compressors have a higher consistency, thereby improving the detection accuracy of the temperature detection component. Since the consistency of the installation position of the temperature detection component is improved, after the temperature detected by the temperature detection component matches the control program of the refrigeration equipment, the deviation between the temperature detected by the temperature detection component and the preset control program is reduced, thereby reducing the fluctuation during the operation of the compressor, and the control program of the refrigeration equipment controls the accuracy of the compressor operation process.

[0009] Specifically, during the assembly of the compressor, the limiting component is first fixed to the housing, and then the temperature detecting component is inserted into the mounting cavity through the first opening until the temperature detecting component contacts the positioning portion.

[0013] In this technical solution, the limiting component also includes a mounting portion, which extends from the first side to the second side, first in a direction away from the shell, and then in a direction close to the shell, thereby forming a mounting cavity between the mounting portion and the surface of the shell to facilitate limiting the temperature detection component.

[0014] The limiting component also includes at least two fixing parts, which are respectively connected to the first side of the mounting part and the second side of the mounting part, and are connected to the housing. The at least two fixing parts can be installed and fixed on both sides of the mounting part, thereby improving the stability of the mounting part. At least two fixing parts are installed and fixed on both sides of the mounting part. The mounting part can press the temperature detection component more stably on the surface of the housing, thereby improving the tightness of the contact between the temperature detection component and the housing, and the temperature detected by the temperature detection component can be closer to the actual temperature of the housing surface. At least two fixing parts are installed and fixed on both sides of the mounting part, so that the mounting part can be pressed more stably on the temperature detection component. After the temperature detection component is installed, due to the higher stability of the mounting part, the tightness of the contact between the temperature detection component and the housing is also more consistent, further improving the detection accuracy of the temperature detection component, reducing the deviation between the temperature detected by the temperature detection component and the preset control program, thereby reducing the fluctuation during the operation of the compressor, and the control program of the refrigeration equipment controls the accuracy of the compressor operation process.

DETAILED DESCRIPTION

[0070] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0071] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0072] Refer to the following Figures 1 to 9 The present invention describes a compressor and a refrigeration device according to some embodiments of the present invention.

[0073] In one embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a compressor is provided, comprising a housing 100, a limiting component 200, and a temperature detection component 300. The limiting component 200 is connected to the housing 100, and the limiting component 200 and the housing 100 enclose a mounting cavity 210. A first opening 220 is provided on at least one side of the mounting cavity 210. The limiting component 200 includes a positioning portion 230, which is located on a side of the mounting cavity 210 away from the first opening 220. The positioning portion 230 protrudes from the inner wall 212 of the mounting cavity 210 toward the interior of the mounting cavity 210. The temperature detection component 300 is inserted into the first opening 220, extends into the mounting cavity 210, and abuts against the positioning portion 230.

[0074] In this embodiment, the compressor includes a housing 100 and a limiting component 200 . The limiting component 200 is connected to the housing 100 , and the housing 100 supports the limiting component 200 , thereby improving the stability of the limiting component 200 . An installation cavity 210 is defined between the limiting component 200 and the shell 100, and a first opening 220 is provided on at least one side of the installation cavity 210. The compressor also includes a temperature detection component 300, which is inserted into the installation cavity 210 through the first opening 220. The limiting component 200 can install and fix the temperature detection component 300, thereby improving the stability of the temperature detection component 300. Moreover, since a first opening 220 is provided on at least one side of the installation cavity 210, when installing the temperature detection component 300, the temperature detection component 300 can be installed by inserting the temperature detection component 300 into the installation cavity 210 through the first opening 220, thereby simplifying the installation process of the temperature detection component 300, reducing the difficulty of installing the temperature detection component 300, and improving the installation efficiency of the temperature detection component 300.

[0075] The limiting component 200 includes a positioning portion 230 located on a side of the mounting cavity 210 away from the first opening 220. The positioning portion 230 protrudes from the inner wall 212 of the mounting cavity 210 toward the interior of the mounting cavity 210. After the temperature sensing component 300 is inserted into the mounting cavity 210, it abuts against the positioning portion 230, thereby positioning the temperature sensing component 300. Because the limiting component 200 is provided with the positioning portion 230 protruding into the mounting cavity 210, the installation position of the temperature sensing component 300 of different compressors is more consistent, thereby improving the detection accuracy of the temperature sensing component 300. Due to the improved consistency of the installation position of the temperature sensing component 300, the temperature detected by the temperature sensing component 300 matches the control program of the refrigeration equipment, reducing the deviation between the temperature detected by the temperature sensing component 300 and the preset control program, thereby reducing fluctuations in the operation of the compressor and improving the accuracy of the control program of the refrigeration equipment in controlling the operation of the compressor.

[0076] Specifically, during the compressor assembly process, the limiting component 200 is first fixed to the housing 100 , and then the temperature sensing component 300 is inserted into the mounting cavity 210 through the first opening 220 until the temperature sensing component 300 contacts the positioning portion 230 .

[0077] Specifically, if Figure 5 As shown, the temperature detection component 300 can be a component for detecting temperature, such as a temperature sensor or a temperature probe.

[0078] Specifically, the housing 100 may be an upper housing, a lower housing, or a cover of the compressor.

[0079] This embodiment provides a compressor. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0080] like Figure 6 and Figure 8 As shown, the limiting component 200 further includes a mounting portion 240 and at least two fixing portions 250. The mounting portion 240 first moves away from the housing 100 from the first side to the second side ( Figure 8 The direction indicated by the arrow A in the middle) extends and then extends toward the direction close to the housing 100 ( Figure 8 at least two fixing portions 250 are respectively connected to the first side of the mounting portion 240 and the second side of the mounting portion 240, and are connected to the housing 100.

[0081] In this embodiment, the limiting component 200 also includes a mounting portion 240, which extends from the first side to the second side first in a direction away from the shell 100, and then extends in a direction close to the shell 100, thereby forming a mounting cavity 210 between the mounting portion 240 and the surface of the shell 100 to facilitate limiting the temperature detection component 300.

[0082] The limiting component 200 also includes at least two fixing portions 250, which are respectively connected to the first side and the second side of the mounting portion 240, and are connected to the housing 100. The at least two fixing portions 250 can be mounted and fixed on both sides of the mounting portion 240, thereby improving the stability of the mounting portion 240. The at least two fixing portions 250 mount and fix both sides of the mounting portion 240, allowing the mounting portion 240 to more stably press the temperature sensing component 300 against the surface of the housing 100, thereby improving the contact between the temperature sensing component 300 and the housing 100, and the temperature detected by the temperature sensing component 300 is closer to the actual temperature of the housing 100 surface. Furthermore, the at least two fixing portions 250 mount and fix both sides of the mounting portion 240, ensuring that the mounting portion 240 is more stably pressed against the temperature sensing component 300. After the temperature detection component 300 is installed, since the installation part 240 has higher stability, the degree of contact between the temperature detection component 300 and the shell 100 is also more consistent, further improving the detection accuracy of the temperature detection component 300, and reducing the deviation between the temperature detected by the temperature detection component 300 and the preset control program, thereby reducing the fluctuation in the working process of the compressor, and the control program of the refrigeration equipment controls the accuracy of the working process of the compressor.

[0083] Furthermore, there are two fixing portions 250 , which are respectively disposed on both sides of the mounting portion 240 and connected to the housing 100 .

[0084] The number of fixing portions 250 may also be four, and the four fixing portions 250 are respectively disposed on both sides of the mounting portion 240 and connected to the housing 100. Two fixing portions 250 may be disposed on each side of the mounting portion 240; alternatively, one fixing portion 250 may be disposed on one side of the mounting portion 240 and three fixing portions 250 may be disposed on the other side of the mounting portion 240.

[0085] The number of the fixing portions 250 may also be five or six. The five or six fixing portions 250 are respectively disposed on both sides of the mounting portion 240 and connected to the housing 100 .

[0086] Furthermore, the mounting portion 240 extends in a broken line, or the mounting portion 240 extends in an arc shape.

[0087] This embodiment provides a compressor. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0088] like Figure 8 As shown, at least two fixing portions 250 are welded to the housing 100 ; and / or the compressor further includes a connecting member 400 , which passes through the fixing portion 250 and is connected to the housing 100 .

[0089] In this embodiment, at least two fixing portions 250 are welded to the housing 100, thereby securing the position-limiting component 200 and improving the stability of the position-limiting component 200. Furthermore, the welding of the fixing portions 250 to the housing 100 reduces the probability of separation between the fixing portions 250 and the housing 100 due to factors such as compressor vibration, thereby improving the reliability of the position-limiting component 200 and extending its service life.

[0090] The compressor further includes a connector 400, which passes through the fixing portion 250 and is connected to the housing 100, thereby securing the position-limiting component 200 and improving the stability of the position-limiting component 200. Furthermore, the securing of the position-limiting component 200 by the connector 400 facilitates disassembly and maintenance of the position-limiting component 200 and the temperature sensor.

[0091] Specifically, the fixing portion 250 is welded to the housing 100. The fixing portion 250 can be a sheet metal part that is attached to the surface of the housing 100. The fixing portion 250 can be provided with a through hole for welding, and a welder welds the fixing portion 250 to the housing 100 at the through hole; the fixing portion 250 can also be welded to the housing 100 at the edge of the fixing portion 250 using a welder.

[0092] Specifically, the fixing portion 250 is fixed to the housing 100 via a connector 400, which can be a screw, rivet, or other connecting component. If the connector 400 is a screw, a threaded hole can be provided in the housing 100, and a through hole can be provided in the fixing portion 250. The screw passes through the through hole and is screwed into the threaded hole in the housing 100, thereby installing and securing the fixing portion 250. Alternatively, a nut can be welded to the housing 100, and the screw passes through the through hole in the fixing portion 250 and is screwed into the nut, thereby installing and securing the fixing portion 250.

[0093] After the fixing portion 250 is fixed to the housing 100 via the connecting piece 400 , the fixing portion 250 and the connecting piece 400 may be welded to prevent the connecting piece 400 from falling off due to factors such as vibration, thereby improving the stability of the connection between the fixing portion 250 and the housing 100 .

[0094] Furthermore, a pin hole is provided on the housing 100 , and the compressor further includes a pin, which is passed through the pin hole and connected to the fixing portion 250 , thereby achieving positioning between the fixing portion 250 and the housing 100 .

[0095] No pins may be provided between the fixing portion 250 and the housing 100 , and the relative position between the housing 100 and the fixing portion 250 may be restricted by tooling.

[0096] This embodiment provides a compressor. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0097] like Figure 3 、 Figure 4 and Figure 7 As shown, the limiting component 200 further includes a guide portion 260, which is connected to the mounting portion 240 and arranged around the first opening 220.
