Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a variable frequency compressor. Background Technology

[0002] With the increasing application and popularization of commercial variable frequency compressors in the light commercial sector, the simple, convenient, time-saving and labor-saving installation of variable frequency board components is an important function required by manufacturers of light commercial refrigeration appliances (freezers, ice cream cabinets, cola cabinets, wine cabinets, etc.).

[0003] Specifically, when installing and connecting the compressor and inverter board assembly in light commercial refrigeration appliances (freezers, ice cream freezers, cola freezers, wine freezers, etc.), it is necessary to find a location in the compressor compartment of the refrigeration appliance to install and fix the inverter board assembly. The wiring harness on the inverter board assembly is connected to the compressor wiring harness in the junction box on the back of the compressor. This method is cumbersome, time-consuming, space-consuming, inefficient, and requires a long wire length. Utility Model Content

[0004] To overcome the problems of cumbersome and time-consuming installation and connection processes of existing frequency converter board assemblies and compressors, this utility model provides a frequency converter compressor.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The variable frequency compressor includes a compressor and a variable frequency board assembly. A junction box is located on the back of the compressor. The wiring harness of the variable frequency board assembly is connected to the wiring harness of the compressor. The side of the junction box away from the back of the compressor extends outward to form an installation platform. The variable frequency board assembly is connected to the installation platform.

[0007] In this application, the installation and connection process of the inverter board assembly and the compressor is simplified by improving the junction box structure on the back of the compressor. Specifically, the inverter board assembly is connected and installed on the mounting platform formed by the outward extension of the junction box, which avoids the need to find a suitable location for installation in practice, thus simplifying the subsequent installation process. Moreover, this implementation requires shorter wire lengths and can be standardized for production. The mounting platform is formed by the outward extension of the junction box, so that the space occupied after the inverter assembly and the compressor are connected and installed is smaller.

[0008] In some embodiments, the minimum height of the mounting platform is higher than the minimum height of the compressor in the vertical direction.

[0009] In some embodiments, the inverter board assembly only contacts the mounting platform on its bottom surface, with a gap between the side surface and the junction box.

[0010] In some embodiments, the mounting platform extends outward from the bottom of the junction box.

[0011] In some embodiments, the inverter board assembly is detachably connected to the mounting platform.

[0012] In some embodiments, the inverter board assembly and the mounting platform are provided with corresponding mounting holes, and the inverter board assembly and the mounting platform are detachably connected by bolts and mounting holes.

[0013] In some embodiments, the inverter board assembly has a pin on its bottom surface and a corresponding socket on the mounting platform. The inverter board assembly and the mounting platform are detachably connected via the pin and the socket.

[0014] The beneficial effects of this utility model are:

[0015] By improving the structure of the junction box on the back of the compressor and modularizing it, the step of finding a fixed location for the refrigeration appliance is eliminated, making the operation simple, quick, time-saving, and space-saving. Specifically, the inverter board assembly is connected and installed on the mounting platform formed by the outward extension of the junction box, avoiding the need to find a suitable location for installation in practice, thus simplifying the subsequent installation process. Moreover, this implementation requires shorter wire lengths and can be standardized for production. The mounting platform is formed by the outward extension of the junction box, so that the space occupied after the inverter assembly and compressor are connected and installed is smaller.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] like Figure 1-3 As shown, this utility model provides a variable frequency compressor.

[0023] The variable frequency compressor includes a compressor 1 and a variable frequency board assembly 3. A junction box 2 is provided on the back of the compressor 1. The wiring harness of the variable frequency board assembly 3 is connected to the wiring harness of the compressor 1. The side of the junction box 2 away from the back of the compressor 1 extends outward to form an installation platform 21. The variable frequency board assembly 3 is connected to the installation platform 21.

[0024] In this application, the installation and connection process of the inverter board assembly 3 and the compressor 1 is simplified by improving the structure of the junction box 2 on the back of the compressor 1. Specifically, the inverter board assembly 3 is connected and installed on the installation platform 21 formed by the outward extension of the junction box 2, which avoids the need to find a suitable location for installation in practice, thus simplifying the subsequent installation process. Moreover, the required wire length is shorter and can be standardized for production. The installation platform 21 is formed by the outward extension of the junction box 2, so that the space occupied after the inverter assembly and the compressor 1 are connected and installed is smaller.

[0025] The junction box 2 on the back of the compressor 1 is existing technology. The connection between the junction box 2 and the compressor 1 will not be described in detail here. The connection method between the junction box 2 and the compressor 1 is not the focus of protection in this application. Therefore, no specific restrictions are made on the connection method between the junction box 2 and the compressor 1.

[0026] In this embodiment, the lowest height of the mounting platform 21 is higher than the lowest height of the compressor 1 in the vertical direction.

[0027] Considering that compressor 1 may vibrate during actual operation, the above implementation is preferred to avoid interference between junction box 2 and other components when compressor 1 is running.

[0028] In this embodiment, the inverter board assembly 3 only contacts the mounting platform 21 on its bottom surface, and there is a gap between its side surface and the junction box 2.

[0029] The above implementation facilitates heat dissipation of the inverter board assembly 3.

[0030] In this embodiment, the installation platform 21 is formed by extending outward from the bottom of the junction box 2.

[0031] This implementation allows the inverter board assembly 3 to be positioned lower, optimizing the overall space occupied by the device and facilitating its implementation.

[0032] In this embodiment, the frequency converter board assembly 3 is detachably connected to the mounting platform 21.

[0033] The detachable connection of the frequency converter board assembly 3 enables the replacement and maintenance of the frequency converter board assembly 3, facilitating implementation and improving the applicability of the device.

[0034] In this embodiment, the inverter board assembly 3 and the mounting platform 21 are respectively provided with mounting holes 50, and the inverter board assembly 3 and the mounting platform 21 are detachably connected by bolts 60 and mounting holes 50.

[0035] In some embodiments, the inverter board assembly 3 is provided with a pin on its bottom surface and a corresponding socket is provided on the mounting platform 21. The inverter board assembly 3 and the mounting platform 21 are detachably connected by the pin and the socket.

[0036] The inverter board assembly 3 and the mounting platform 21 are detachably connected in the manner described above to facilitate operation.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
