Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The main solution of the embodiment of the present invention is: the air conditioner is provided with a control circuit of the AC fan, and after the air conditioner obtains the operating current value of the AC fan detected by the detection unit on the control circuit of the AC fan, control The air conditioner executes an action corresponding to the operating current value.

[0042] Based on the indirect detection of the working state of the AC fan of the air conditioner, the detection result is inaccurate and there is a problem of hysteresis. The present invention proposes a control circuit of the AC fan, and a direct detection of the current of the AC fan is set on the control circuit of the AC fan. The current detection unit judges the working state of the AC fan by detecting the working current of the AC fa...

Abstract

The invention discloses a control circuit of an alternating-current fan. The control circuit of the alternating-current fan comprises a controller, a fan driving unit and a current detection unit, wherein the fan driving unit is connected between the controller and the alternating-current fan and is used for starting or stopping the alternating-current fan according to a control signal of the controller; and the current detection unit is connected between the alternating-current fan and the controller and is used for detecting the current of the alternating-current fan and outputting the current to the controller. The invention further provides a state detection method of the alternating-current fan of an air conditioner. The current detection unit is arranged on the control circuit of thealternating-current fan and is used for detecting the working current of the alternating-current fan in real time or regularly, and different working currents reflect different working states of thealternating-current fan; and the working state of the alternating-current fan is detected by directly detecting the working current, so that detection is more accurate and timely, and hysteresis is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control circuit of an AC fan, an air conditioner and a method for detecting the state of the AC fan, and a storage medium. Background technique [0002] Whether the status of the AC fan of the air conditioner is abnormal is generally determined by detecting whether the temperature of the condenser is abnormal. Using this indirect method to detect the status of the fan is not accurate enough and has hysteresis. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a control circuit of an AC fan, an air conditioner and a method for detecting the state of the AC fan and a storage medium thereof, aiming at solving the technical problems of inaccurate dete...
