Problems solved by technology

Under this control method, although the air conditioner can enter the sleep mode relatively intelligently, it only reduces the speed of the indoor fan motor, and the effect is single. Although the noise is low, it may still cause poor cooling and heating

Embodiment 1

[0026] Below with the air conditioner of 1.5 horses in the state of cold room, illustrate content of the present invention by way of example.

[0027] When the air conditioner is running in a cold room, when the air conditioner is in the normal mode, if the light sensor detects that the current light brightness S45Lx (default value A), then exit the sleep mode;

[0028] After entering the sleep mode, first limit the maximum limit value C of the indoor fan motor speed, and the maximum limit value is set to 680rpm; then according to the difference D between the currently detected indoor air temperature T1 and the temperature T2 set by the remote control (that is, T1-T2) to determine the current area, and then determine the operating frequency of the compressor and the actual speed of the indoor fan motor. Such as Figure 4 As shown, it is divided into three regions, and the D value is in a downward trend. When D>0.5℃, it is region 3; when -1.0℃<D≤0.5℃, it is region 2; when D≤-...

Abstract

The invention discloses a method for controlling a sleep mode of an air conditioner. The method comprises the following steps of: performing indoor brightness detection through an optical sensor, and determining whether the air conditioner is in a sleep mode according to the brightness detection result; and detecting the indoor air temperature through an indoor air temperature sensor, and controlling the operating frequency of a compressor and the rotating speed of an indoor fan motor according to the difference between the indoor air temperature and the current temperature set by a remote controller. The room brightness intensity is detected, so that whether the air conditioner is in the sleep mode is judged, meanwhile the indoor air temperature is detected, the detection result is integrated according to the difference between the indoor air temperature and the current temperature set by the remote controller, the operating frequency of the compressor and the rotating speed of the indoor fan motor are intelligently controlled, low noise is realized, the refrigeration and heating effects are ensured, and a silent and comfortable sleep mode is realized.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method for controlling the sleep mode of the air conditioner. Background technique [0002] At present, the sleep mode of the air conditioner is mainly realized through the following two control methods: [0003] a kind of like figure 1 As shown, on the product with sleep mode function, the indoor fan motor speed will be reduced through artificial setting operation (remote control operation to enter), this control method has a single entry method, and cannot enter the sleep mode intelligently. And it may lead to poor cooling and heating. [0004] another such as figure 2 As shown, it automatically enters the sleep mode according to a specific detection (such as a light sensor), but after entering the sleep mode, the low-noise effect is achieved simply by reducing the speed of the indoor fan motor. At this time, the so-called sleep mode is quiet and low-noise operation model...
