Air conditioner

Abstract

The invention discloses an air conditioner. The air conditioner comprises a controller, a cleaning box and a liquid level switch; a water inlet and a water overflow port are formed in the upper part of the cleaning box; a drain port is formed in the bottom of the cleaning box; the liquid level switch is connected with the controller and is used for detecting the liquid level in the cleaning box; cleaning of a filter net includes water cleaning and dry cleaning according to the fact whether the liquid level in the cleaning box reaches a preset liquid level; when the liquid level switch detects that the liquid level in the cleaning box reaches the preset liquid level, the controller judges the dry cleaning time number recorded at the moment, if the dry cleaning time number is larger than or equal to N, the drain port is controlled by the controller to be opened to drain water in the cleaning box, if the dry cleaning time number is smaller than N, the cleaning box is controlled by the controller to perform water cleaning on the filter net, and N is a positive integer. According to the air conditioner, the liquid level switch is arranged on one side wall of the cleaning box, and the controller which is connected with the liquid level switch and can control opening and closing of the drain port is also arranged, so that the cleaning effect of the cleaning box on the filter net is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner. Background technique [0002] After the air conditioner is used for a period of time, a layer of dirt will accumulate on the filter screen, which includes dust, textile fibers and animal hair, etc., and will produce a large number of harmful substances such as bacteria and viruses. If the filter screen is not cleaned regularly, these harmful substances will circulate indoors with the air when the air conditioner is running, polluting the air, spreading diseases, and causing adverse effects on the health of users. Moreover, these dirt will reduce the cooling and heating efficiency of the air conditioner, increase energy consumption, and shorten the service life of the air conditioner. [0003] Since the cleaning water of the cleaning box of the air conditioner comes from the condensed water produced by the cooling of the air conditioner, and there is ...

AI Technical Summary

Problems solved by technology

However, the air conditioner has been heated for a long time in winter, and the cleaning box has dry-cleaned the filter screen several times. The dust on the filter screen is washed off by the cleaning box and accumulated in the cleaning box. The condensed water flows into the cleaning box. At this time, the cleaning box washes the filter screen with water, and the dust accumulated in the cleaning box will float on the water surface after being soaked in water in the cleaning box, thus polluting the filter screen during the washing process and affecting the filtration.
