Air conditioner indoor unit with self-cleaning function

Abstract

The invention provides an air conditioner indoor unit with a self-cleaning function. The air conditioner indoor unit comprises a case, a humidifying assembly, a spray opening and a heat exchanger of the indoor unit. The case comprises a skeleton and a housing, wherein the skeleton is used for supporting a fan and the heat exchanger of the indoor unit, and the housing covers the skeleton and is provided with an air inlet and an air outlet. The humidifying assembly comprises a water tank and an atomization device used for atomizing water in the water tank. The spray opening is formed in the case and located in the air inlet upstream position of the heat exchanger of the indoor unit and used for outputting water mist formed by the atomization device. The humidifying assembly starts the atomization device when the air conditioner indoor unit executes the self-cleaning function, so that the spray opening is utilized to spray out the water mist to flow through the heat exchanger of the indoor unit, and accordingly the frosting degree at the heat exchanger of the indoor unit is improved. The heat exchanger of the indoor unit operates a condenser mode after frosting, and accordingly attached contaminants are taken away by water formed by defrosting. According to the scheme, the problem that a self-cleaning air conditioner cannot generate enough condensed water in the dry environment, and consequently the self-cleaning effect is affected is solved.

Description

technical field [0001] The invention relates to a household air conditioner, in particular to an air conditioner indoor unit with self-cleaning function. Background technique [0002] After the air conditioner is placed or used for a long time, there will be a lot of dust in the air conditioner. The dust attached to the heat exchanger of the indoor unit will reduce the heat transfer performance of the heat exchanger on the one hand, resulting in a decrease in the performance of the air conditioner and an increase in energy consumption; Bacteria and mildew will produce peculiar smell in the unit, if not cleaned in time, it will seriously threaten the health of air conditioner users. [0003] The solution adopted by traditional air conditioners is generally to clean them regularly, which brings serious inconvenience to users. Therefore, in order to solve the above-mentioned problems caused by the adhesion of dust and dirt on the heat exchanger of the air conditioner, the exis...

AI Technical Summary

Problems solved by technology

The dirt adheres to the heat exchanger of the indoor unit. On the one hand, it will reduce the heat transfer performance of the heat exchanger, resulting in a decrease in the performance of the air conditioner and an increase in energy consumption; Bacteria and mildew will produce peculiar smell in the unit, if not cleaned in time, it will seriously threaten the health of air conditioner users

[0003] The solution adopted by traditional air conditioners is generally to clean them regularly, which brings serious inconvenience to users. Therefore, in order to solve the above-mentioned problems caused by the adhesion of dust and dirt on the heat exchanger of the air conditioner, the existing technology has appeared to use the heat exchanger as an evaporator. When the air conditioner is in use, condensed water is generated, and the dust on the surface of the heat exchanger is taken away by the condensed water, so as to realize the self-cleaning of the heat exchanger of the indoor unit of the air conditioner

[0004] However, the above-mentioned scheme of using condensed water to clean the heat exchanger of the indoor unit of the air conditioner, in the actual use process, it is found that the cleaning effect will be unsatisfactory, which affects the use of users.
