Technical Field

[0001] The utility model relates to the technical field of inverters, in particular to a special DC inverter device for a power background with waterproof and moisture-proof functions. Background Technique

[0002] An inverter is a converter that converts DC electrical energy into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated AC electrical energy. It consists of an inverter bridge, control logic, and a filter circuit. Generally, it is composed of a boost circuit and an inverter bridge circuit. The boost circuit boosts the DC voltage to the DC voltage required for the output control of the inverter, and the inverter bridge circuit equivalently converts the boosted DC voltage into an AC voltage of a common frequency. Therefore, it is widely applicable to equipment components such as air conditioners, home theaters, electric grinders, power tools, sewing machines, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, and lighting. For heat dissipation, the inverter is generally installed outdoors;

[0003] The inverters installed outdoors generally use a cabinet as the main loading component. Some components of the inverter are arranged inside the cabinet, and heat dissipation holes for heat dissipation are opened on both side walls of the cabinet. As a result, during the use of the inverter, the rainwater that falls will flow along the side wall of the cabinet into the heat dissipation holes, and then flow into the cabinet through the heat dissipation holes, causing the electrical components inside the cabinet to be soaked by the rainwater and easily damaging the inverter. Therefore, a special DC inverter device for a power background with waterproof and moisture-proof functions is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a special DC inverter device for a power background with waterproof and moisture-proof functions to solve the above problems.

A plurality of water outlet holes communicated with the water guide grooves are evenly opened on the side surface of the DC inverter box body. A first drying member is arranged at the inner end of the heat dissipation groove. Second drying members are symmetrically arranged inside the DC inverter box body.

[0007] Preferably, the first drying member includes an annular rubber ring arranged in the heat dissipation groove. A first mesh box is installed on the annular rubber ring. A drying agent is filled in the first mesh box.

[0008] Preferably, the second drying member includes a mounting rack disposed on the rear end face inside the DC inverter box. A rectangular groove is formed on the front end face of the mounting rack. An installation block is slidably disposed in the rectangular groove. A second net box is provided on the front end face of the installation block. The second net box is filled with a desiccant. Rectangular cavities are symmetrically formed in the installation block, and fixing members are disposed in the rectangular cavities.

[0009] Preferably, the fixing member includes a pressing plate slidably disposed in the rectangular cavity. A fixing rod is provided on one side face of the pressing plate. A plurality of fixing holes are uniformly formed on the inner wall of the rectangular groove. An extrusion spring is disposed between the pressing plate and the rectangular cavity.

[0010] Preferably, a dust-proof net is installed at the outer end of the heat dissipation groove.

[0011] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:
