Automatic dust removal electrical box, outdoor unit and air conditioning unit

Abstract

The invention relates to an automatic dust removing type electric appliance box, an outdoor unit and an air conditioning unit. The automatic dust removing type electric appliance box comprises an electric appliance box shell. Windows are formed in the electric appliance box shell and provided with filter screens. The electric appliance box shell is provided with automatic dust removing devices which comprise dust removing components. The dust removing components can reciprocate along the filter screens so as to clean the filter screens. Due to the fact that the automatic dust removing devices are arranged in the positions of the filter screens, dust accumulated on the filter screens can be automatically removed, it is guaranteed that air flows into the windows normally to take away heat in the electric appliance box, and safe and normal work of electronic elements is guaranteed.

Description

technical field [0001] The invention relates to the field of electrical components, in particular to an automatic dust-removing electrical box, an outdoor unit and an air-conditioning unit. Background technique [0002] The electrical box of the outdoor unit of the air conditioner is in an outdoor environment. In order to prevent the intrusion of dust and debris, a sealed structure is generally adopted. However, as the load of the outdoor unit of the air conditioner increases, the heat generated by the electronic components inside the electrical box is also increasing. , the life of electronic components is directly affected by the temperature of their working environment. Therefore, it is very important to effectively dissipate heat inside the electrical box. [0003] At present, it is a simple and economical way to add heat dissipation windows to the electrical box and use air ducts to introduce flow to dissipate heat from the internal electrical components, but this will ...

Problems solved by technology

[0003] At present, it is a simple and economical way to add heat dissipation windows to the electrical box and use air ducts to introduce flow to dissipate heat from the internal electrical components, but this will also bring dust and debris into the interior of the electrical box from the heat dissipation windows, and accumulate On the PCB board and electronic components, it affects the heat dissipation of the components, and even causes electrical safety problems such as short circuits, which seriously affects the service life of the equipment

The existing method is to add a filter screen on the heat dissipation window to reduce the entry of dust and debris, but after a long time, the dust and debris accumulate on the filter screen, blocking the mesh, affecting the external airflow into the inside of the electrical box, thereby affecting the electronic components. Heat dissipation, reducing the service life of components
