Embodiment Construction

[0041] The present application is further described in conjunction with the following examples.

[0042] Such as Figure 1 to Figure 3 , an air conditioner, comprising a housing, an air inlet, an air outlet, an air deflector, an air volume adjustment module 1, a control module 2, a fan module 3, a detection module 4 and a display module 5; the air deflector is located at the outlet on the tuyere, and driven by a motor to swing; the air volume adjustment module 1 is located at the air inlet; the control module 2 is electrically connected to the air volume adjustment module 1, the fan module 3, the detection module 4, and the display module 5 respectively sexual connection; the fan module 3 includes a fan motor; the detection module 4 is a speed sensor. By setting the air volume adjustment module 1 at the air inlet, it is used to adjust the air intake of the air inlet. When the detection module 4 detects that the speed control signal of the fan motor is lower than the original ...

Abstract

The invention relates to a control method of the constant air volume of an air conditioner indoor unit. An air volume adjusting module for adjusting the air inlet volume is arranged at an air inlet. Whether the rotating speed control signal of a fan motor is lower than original data or not is judged, and if yes, the air volume adjusting module is driven to work to increase the air inlet volume ofthe air inlet. By means of the control method of the constant air volume of the air conditioner indoor unit, the control over the constant air volume is realized, and the problem that user experienceis affected when the air conditioner is blocked by dirt and the performance of the air conditioner is degraded is avoided. The invention further provides the air conditioner for implementing the control method of the constant air volume of the air conditioner indoor unit.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a method for controlling the constant air volume of an air conditioner internal unit, and also relates to an air conditioner for realizing the method for controlling the constant air volume of an air conditioner internal unit. Background technique [0002] In daily life, when the air inlet of the air conditioner is dirty and blocked, the air intake volume of the air conditioner becomes smaller, resulting in reduced heat exchange of the evaporator of the air conditioner, lowering the performance of the air conditioner, and resulting in poor user experience. Therefore, in the existing technology, the detection of the change of the fan current of the fan is used to determine the degree of dirty blockage at the air inlet, and the constant wind of the air conditioner is maintained by adjusting the motor speed. However, due to the loss of the current of the circuit duri...
