Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The invention provides an indoor unit of an air conditioner. like figure 1 and figure 2 As shown, the indoor unit of the air conditioner is provided with a heat exchanger 10 , an indoor fan 20 , an electric control board 30 and an indoor motor 40 for driving the indoor fan 20 . The electric control board 30 is provided with a control device 50 for controlling the dirty blockage of the outdoor unit, and the control device 50 includes:

[0047] The motor information acquisition unit 51 is used to acquire the operating parameters of the motor, and the operating parameters include motor speed, motor voltage, and motor current;

[0048] The real-time power calculation unit 52 is used to calculate and obtain the real-time power of the motor according to the motor voltage and the motor current;

[0049] The first...

Abstract

The invention discloses a method for filth blockage control of an air conditioner. The method for filth blockage control comprises: acquiring real-time power of a motor, considering influence of air conditioner input voltage, heat exchanger temperature and wind guiding angles on power of the motor, to correct the real-time power of the motor, so as to obtain a new filth blockage value, then comparing the new filth blockage value with a preset filth blockage standard value which is corresponding to the rotating speed same with the rotating speed of the motor, to determine whether the air conditioner meets filth blockage conditions; and when the air conditioner meets the filth blockage conditions, prompting users to perform filth blockage processing. The invention also discloses a device for filth blockage control and an air conditioner indoor unit. The method and the device can accurately detect filth blockage conditions and timely dedusting requirement of an indoor heat exchanger and / or a filter screen, and the method and the device are not influenced by network voltage of a user, temperature of a heat exchanger, and wind-guiding angles and other factors, and refrigeration and heating effects of the air conditioner are ensured, and user health degree and comfortableness are further improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method and device for controlling dirty blockage of an air conditioner and an indoor unit. Background technique [0002] At present, the indoor units of air conditioners are equipped with filter screens, and the dust is deposited on the filter screens after being filtered. Users need to clean them regularly, otherwise bacteria will easily breed and cause secondary pollution, and dust will affect the air supply volume and air supply distance of the indoor units. Thus affecting the cooling and heating effect of the air conditioner. At the same time, the heat exchanger of the indoor unit is also prone to dust collection, and the dust on the heat exchanger will also affect the air supply volume of the indoor unit, thereby affecting the cooling and heating effects of the air conditioner. [0003] In view of this, in the process of research on air conditioner dirty blockage control, ...
