Automatic ash removal device for outdoor unit of outdoor air conditioner in northern area

Abstract

The invention relates to the field of air conditioner outdoor unit cleaning, in particular to an automatic ash removal device for an outdoor unit of an outdoor air conditioner in the northern area. The automatic ash removal device comprises a rotating portion and a flow guide sheet. The flow guide sheet is fixedly connected in the rotating portion. The lower end of the rotating portion is movablyconnected with a rotating layer. A cleaning wheel is fixedly connected to the rotating layer. The flow guide sheet is mounted on the periphery in the rotating portion, the left side of the flow guidesheet is obliquely arranged in an inwards concaved manner, the inwards concaved radian of the upper end of the flow guide sheet is larger than that of the lower end of the flow guide sheet, when windblows over, airflow can pass through the flow guide sheet, acting force to the rotating portion can be increased through inclination and inwards concaving of the upper end, and therefore the rotatingportion can be driven to rotate more easily; and an airflow groove and air stop blocks are arranged on the flow guide sheet, the airflow groove gradually becomes smaller from bottom to top and is arranged in an inwards concaved arc shape, the air stop blocks are staggered, and are overall triangular, the lower end of each air stop block is in an inwards concaved arc shape, the airflow can enter more easily, meanwhile, the airflow can be stopped more easily during movement, acting force to the flow guide sheet is further increased, and therefore the rotating efficiency of the rotating portion is improved.

Description

technical field [0001] The invention relates to the cleaning field of an air conditioner external unit, in particular to an automatic dust cleaning device for an outdoor air conditioner in northern China. Background technique [0002] Air conditioners are devices that process the temperature, humidity, purity, and airflow velocity of the air to meet the needs of people's production and life. With the improvement of people's living conditions, air conditioners are widely used in family life and office spaces, covering more and more areas. wide. [0003] However, in order for the air conditioner to work normally, it is necessary to install an external unit of the air conditioner outdoors, but the existing external unit of the air conditioner lacks a dust cleaning device, which makes it easy for the loose sand in the Loess Plateau and desert in the north to be blown up by the wind. The sand carries them into the air, making it easy for the heat sink in the northern air conditi...

[0003] However, in order for the air conditioner to work normally, it is necessary to install an external unit of the air conditioner outdoors, but the existing external unit of the air conditioner lacks a dust cleaning device, which makes it easy for the loose sand in the Loess Plateau and desert in the north to be blown up by the wind. The sand carries them into the air, making it easy for the heat sink in the northern air conditioner to accumulate dust and affect the heat dissipation efficiency
