Detecting device for air conditioner wind-sweeping fan blade drive signal, test method for detecting device and air conditioner

Abstract

The invention provides a detecting device for an air conditioner wind-sweeping fan blade drive signal, a test method for the detecting device and an air conditioner. The detecting device comprises a drive circuit which is respectively connected with a master control circuit and an indicator circuit, and is used for receiving a wind-sweeping fan blade signal conveyed by the master control circuit, and converting the wind-sweeping fan blade signal into a wind-sweeping fan blade drive signal; and the indicator circuit is used for receiving the wind-sweeping fan blade drive signal and carrying out indication under the control of the wind-sweeping fan blade drive signal. The detecting device is used for detecting whether the wind-sweeping fan blade drive signal is normal or not before the whole air conditioner is assembled, and is quick and effective, so that the problem that time cost and labor cost are wasted due to the fact that a conventional whole machine test is required to return to repair and re-assemble when a wind-sweeping fan blade is found to be abnormal is avoided, product production quality is guaranteed, and generalizability is high.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a detection device for driving signals of air-conditioning sweeping fan blades, a testing method thereof, and an air conditioner. Background technique [0002] The change of the up, down, left, and right sweeping angles of the air-conditioning sweeping blades is realized by controlling the stepping motor through the main board program of the air-conditioning. The traditional way to test whether the air conditioner’s sweeping fan blades sweep up, down, left, and right is to test the whole machine, that is, before the air conditioner leaves the factory, the whole machine is powered on to see whether the stepping motor operates or whether the action is normal. If it is not normal, the whole machine needs to be tested. Disassemble and reassemble the whole machine after the motherboard is repaired or replaced with a new motherboard. This test method not only wastes a lot of time an...
