Technical Field

[0001] The utility model relates to the technical field of inverters, in particular to an inverter suitable for high-dust environments. Background Art

[0002] Inverter, electricity is indispensable in people's daily life. People not only need low-voltage direct current supplied by batteries or storage batteries, but also need 220-volt alternating current. In order to convert direct current into alternating current, inverters come into being. Inverter is a converter that converts direct current power into constant-frequency and constant-voltage or frequency-modulated and voltage-regulated alternating current. It consists of an inverter bridge, control logic and filter circuit, and is widely used in air conditioners, power tools, computers, televisions and washing machines. Publication No. CN214674921U discloses an inverter, characterized in that it includes: a shell, a suspension assembly and two card-connecting plates, the two card-connecting plates are relatively arranged on the shell, and each of the card-connecting plates is provided with a card-connecting groove, the suspension assembly includes: a wall-mounted fixing plate and two side plates, the two side plates Two clamping protrusions are arranged on the wall-mounted fixing plate at two ends relatively to each other, each of the clamping protrusions is clamped in a clamping groove, each of the clamping plates is provided with a first locking hole, each of the side plates is provided with a second locking hole, and each of the first locking holes is aligned with a second locking hole. In actual application of the above technology, the inverter will emit a lot of heat when working, and the air holes on the surface of the inverter body can release the heat, but the dust in the air will also enter the interior of the inverter body at the same time. When the dust enters the interior of the inverter and adheres to the surface of the electronic components inside the inverter, the resistance of the electronic components will increase, and it may also cause damage to the internal components, thereby increasing the cost of use, and improvement is needed.

The dust cover is connected to the surface of the inverter body by sliding, and can be disassembled and cleaned, thereby increasing the service life of the entire inverter.

[0013] 2. In the utility model, by providing a washer, a movable plate, and a hanging hole structure, the washer helps to place the inverter body on a plane, thereby improving the stability of the inverter. The sliding plate can move inside the washer and the inverter body.
