Air conditioner indoor unit, control method and air conditioner

Abstract

The invention provides an air conditioner indoor unit, a control method and an air conditioner. The air conditioner indoor unit comprises a shell and a fan. The fan is arranged in the shell and is a centrifugal fan. The shell comprises a first side face and a second side face which are oppositely arranged. The first side face and the second side face are both opposite to the axis direction of thecentrifugal fan. A first air inlet is formed in the first side face. A second air inlet is formed in the second side face. According to the air conditioner indoor unit, the control method and the airconditioner, the air inlet area is effectively increased, the air volume of the whole unit can be effectively increased, heat circulation and cold circulation of a room are accelerated, the air conditioner efficiency is improved, power consumption is reduced, and the refrigerating and heating effects of the indoor unit are improved; and the two air inlets are formed in the upper side face and thelower side face correspondingly, a function of up-down air inlet of the air conditioner can be effectively fulfilled, and the air inlet volume of the air conditioner can be remarkably increased through the two air inlets.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit, a control method and an air conditioner. Background technique [0002] Air-conditioning wall-mounted units usually use single-flow as the main fan system, which consists of a single air inlet and a single air outlet. There is a dirty filter at the air inlet, and the evaporator has a large resistance to falling dust. single issue. [0003] In recent years, some manufacturers have also proposed to use double cross-flow fans to realize the partitioned air supply function of wall-mounted machines, but this will lead to the problem that the size of the whole machine is too large, and the appearance does not conform to the public's aesthetics. There are phenomena such as insufficient heating capacity or limited air supply range. [0004] Patent CN110056967A proposes to use double centrifugal to send air forward to realize partitioned air suppl...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is mainly to overcome the disadvantages of the air-conditioning indoor unit in the prior art that the air inlet is concentrated on one side, the air inlet area is small, and the performance of the fan cannot be effectively utilized, thereby providing an air-conditioning indoor unit , control method and air conditioner
