9. The no-wind-feeling control method of the air conditioner is used for controlling the air conditioner, the air conditioner comprises an indoor unit and an outdoor unit, and the no-wind-feeling control method of the air conditioner is characterized in that: the indoor unit of a cabinet air conditioner as claimed in any one of claims 1 to 8, further comprising a temperature sensor electrically connected to the control system;
the outdoor unit comprises a compressor, and the compressor is electrically connected with the control system;
the control method comprises the following steps:
inputting a preset temperature and at least two preset distance ranges in a control system;
step two, acquiring the position of a user through a position detection device and feeding back the position to a control system, and acquiring the indoor temperature of a room where an indoor unit of the cabinet air conditioner is located through a temperature sensor and feeding back the indoor temperature to the control system;
step three, the control system calculates the distance between the user and the indoor unit of the cabinet air conditioner according to the position of the user and corresponds to one of the preset distance ranges; the control system compares the indoor temperature with a preset temperature and calculates the temperature deviation;
step four, the corresponding preset distance range and the corresponding temperature deviation are used as the control input of the control system, and then the control system controls the operation of the driving device and the compressor;
and step five, when the position of the user and/or the indoor temperature is detected to be changed, repeating the step two to the step four.
10. The no-wind feeling control method of the air conditioner according to claim 9, wherein: in the first step, three preset distance ranges of A, B and C are input into a control system, wherein A is more than 0 and less than 0.5m, B is more than or equal to 0.5m and less than or equal to 2m, and C is more than 2 m;
the fourth step also comprises the following steps:
when the distance between the user and the indoor unit is less than 0.5m, the distance corresponds to a preset distance range A, at the moment, the control system controls the driving device to drive the winding drum (220) to wind the air outlet net (210), so that the ribs of the air outlet net (210) shield 2/3 of the cross section area of the air through hole (111);
when the distance between the user and the indoor unit is greater than or equal to 0.5m and less than or equal to 2m, the distance corresponds to a preset distance range B, at the moment, the control system controls the driving device to drive the winding drum (220) to wind the air outlet net (210), so that ribs of the air outlet net (210) shield 1/3 of the cross section area of the air permeable holes (111);
when the distance between the user and the indoor unit is larger than 2 meters, the distance corresponds to a preset distance range C, at the moment, the control system controls the driving device to drive the winding drum (220) to wind the air outlet net (210), and therefore meshes of the air outlet net (210) are overlapped with the air ventilation holes (111).
