Embodiment Construction

[0060] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Such as figure 1 As shown, a first embodiment of the method for controlling dirty blockage of an air conditioner indoor unit according to the present invention is proposed. The method for controlling the dirty blockage of the indoor unit of the air conditioner in this embodiment includes the following steps:

[0062] Step S11, obtaining the operating parameters of the motor, the operating parameters include the motor speed, motor voltage, and motor current;

[0063] The acquisition order of the above-mentioned motor speed, motor voltage and motor current is in no particular order. In this embodiment, for the convenience of description, the first example is the motor speed ω r of acquisition. In this embodiment, specifically through the vector control technology (Field-Oriented Control, FOC) based on the roto...

Abstract

The invention discloses a filth blockage control method of an air conditioner indoor unit. According to the filth blockage control method, firstly real-time power of a motor is obtained; then the influence of air conditioner input voltage, humidity and compressor frequency on motor power is considered, the real-time power of the motor is modified, and therefore a new filth blockage value is obtained; the new filth blockage value is compared with a preset filth blockage standard value corresponding to the rotating speed equal to that of the motor, and whether an air conditioner meets the filth blockage condition or not is judged; when the air conditioner meets the filth blockage condition, a warning message is sent to a user so as to warn the user to remove dust. Factors such as network voltage, environment humidity and compressor frequency which affect filth blockage judgment are considered so that the filth blockage situation of an outdoor heat exchanger and the demands for removing dust timely can be accurately detected; the influence of the factors such as user network voltage, air humidity and compressor frequency is avoided; the refrigeration and heating effects of the air conditioner are guaranteed, and the health degree and comfort of the user are further improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an indoor unit of an air conditioner and a method for controlling dirty blockage thereof. Background technique [0002] At present, all indoor units of air conditioners are equipped with filter screens, and 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 unit. , thus affecting the cooling and heating effects of the air conditioner. However, if the outdoor unit of the air conditioner is placed outdoors, the heat exchanger is also prone to collecting dust. 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 conditione...
