Abstract

The invention relates to a fan blade fault detection device and method, an air conditioner outdoor unit and an air conditioning unit. The device comprises induction devices, a radio frequency identification device and a controller, wherein the induction devices are placed in fan blades through injection molding, and can form closed loops when the fan blades do not crack, and transmits induction signals, the radio frequency identification device is used for receiving the induction signals, and the controller is used for judging whether the fan blades have cracks or not according to the receiving situation of the induction signals. According to the technical scheme, automatic detection of fan blade damage is realized, working states of the fan blades can be simply and effectively judged forusers, meanwhile, aerial work for judging whether the fan blades of the outdoor unit are faulty by the users is avoided, an air conditioner fault caused by continuous operation of the air conditioneroutdoor unit after the fan blades crack is avoided, and the service life of an air conditioner whole machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of air-conditioning units, in particular to a fan blade fault detection device and method, an air-conditioning external unit and an air-conditioning unit. Background technique [0002] During the use of the external fan of the existing split-type air conditioner, there is a risk of cracks in the blades of the fan blades. After the cracks appear on the fan blades, the dynamic balance value of the blades increases, causing vibration of the motor and bracket, and even causing noise in the operation of the external fan. If it is too large, it will cause the fan blades to break completely and cause the external unit of the air conditioner to malfunction, which will affect the service life of the air conditioner. Contents of the invention [0003] In view of this, the object of the present invention is to provide a fan blade fault detection device, method, air conditioner external unit and air conditioner unit t...
