Problems solved by technology

[0003] With this shutdown control method, after the user sends a shutdown command, the user perceives that the air conditioner is still running because the indoor fan is still running, making it impossible for the user to determine the current operating status of the air conditioner, resulting in poor user experience.

Embodiment Construction

[0050] The air conditioner operates in heating mode. After receiving the shutdown command, if the indoor fan of the air conditioner is turned off directly due to the high temperature of the indoor unit, there will be a lot of residual heat in the indoor unit. On the other hand, when the air conditioner starts up again, the residual heat inside the indoor unit accumulates inside the indoor unit, which causes the indoor ambient temperature detected by the indoor ambient temperature sensor to be too high, causing the air conditioner to The device cannot start.

[0051]At present, in order to avoid the residual heat of the indoor unit, after receiving the shutdown command, the compressor of the air conditioner stops running, and the indoor fan needs to continue to run for a certain period of time before turning off the indoor fan and closing the air guide door. This kind of shutdown control method, after the user issues a shutdown command, the user can still perceive the operation...

Abstract

The invention provides an air conditioner shutdown control method and device and an air conditioner. The air conditioner shutdown control method comprises the following steps: a heating shutdown instruction of the air conditioner is acquired; an indoor fan is closed, and a guide damper of an indoor unit is closed; the operation mode of the air conditioner is switched to a refrigeration mode; whether the shutdown condition of a compressor is met or not is judged according to the internal temperature of the indoor unit; if the shutdown condition of the compressor is met, the compressor stops operation. According to the air conditioner shutdown control method, after the heating shutdown instruction of the air conditioner is obtained, residual heat inside the indoor unit is removed through heat absorption by a low-temperature refrigerant flowing through an indoor heat exchanger, a user can sense that the air conditioner stops running after the shutdown instruction is emitted while residualheat inside the indoor unit is removed, and troubles to the user of the air conditioner due to the fact that the indoor fan runs continuously after shutdown and whether the air conditioner is currently in a shutdown process or not cannot be judged are avoided.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner shutdown control method and device, and an air conditioner. Background technique [0002] In the prior art, when the air conditioner is turned off in the heating state, in order to avoid residual heat from the indoor unit, the compressor stops running after receiving the shutdown command, and the indoor fan needs to continue running for a certain period of time before turning off the indoor fan and closing the air guide door. [0003] With this shutdown control method, after the user sends a shutdown command, the user perceives that the air conditioner is still running because the indoor fan is still running, making it impossible for the user to determine the current operating status of the air conditioner, resulting in poor user experience. Contents of the invention [0004] The problem solved by the present invention is that the user percei...
