Embodiment Construction

[0031] The air conditioner in this embodiment can be but not limited to wall-mounted air conditioners, cabinet-type air conditioners, window-type air conditioners, and ceiling-mounted air conditioners, and can include indoor units and outdoor units (those skilled in the art should know that for integrated air conditioners, such as For window air conditioners, the indoor unit can be understood as the part used to exchange heat indoors).

[0032] The air conditioner in this embodiment has the self-cleaning function of the heat exchanger of the indoor unit. The self-cleaning process can be that the indoor unit of the air conditioner generates condensed water through frost condensation and defrosting of the heat exchanger itself, and uses the condensed water to flush the heat exchanger to remove the heat exchanger. The dust and mold on the surface of the heater can be eliminated, and the healthy and clean air supply of the air conditioner can be realized. Since the self-cleaning p...

Abstract

The invention provides a heat exchanger self-cleaning control method of an air conditioner indoor unit and an air conditioner. The self-cleaning control method comprises the steps of recording an operation state of the indoor unit; calculating dirt accumulation parameters of a heat exchanger according to the operation state; matching the dirt accumulation parameters with a preset cleaning strategyto determine a cleaning mode of the indoor unit, wherein a corresponding relation between a dirt accumulation parameter range and a cleaning mode is stipulated in the cleaning strategy; and making the indoor unit and / or control equipment of the indoor unit execute the cleaning mode. Due to a fact that the dirt accumulation parameters are obtained through operation state statistics of the indoor unit, a dirt accumulation condition of the heat exchanger is reflected, self-cleaning is ensured to be executed when the heat exchanger needs to be cleaned, self-cleaning mistaken starting or untimelystarting is avoided, an intelligent level is improved, and a requirement of a user for intelligent household appliances is met.

Description

technical field [0001] The invention relates to intelligent home appliance control, in particular to a heat exchanger self-cleaning control method of an indoor unit of an air conditioner and the air conditioner. Background technique [0002] After the indoor unit of 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 and cause the performance of the air conditioner to decline; Odors are generated in the unit, if not cleaned up in time, it will seriously threaten the health of air conditioner users. [0003] In order to solve the above-mentioned problems caused by the adhesion of dirt on the heat exchanger of the air conditioner, a technical means has emerged in the prior art to use the heat exchanger as an evaporator to generate condensed water and take away the dirt on the surface o...
