[0003] There is no method for judging whether the external unit is powered on in the existing air conditioner units. If the air conditioner unit does not start because the external unit is not powered on, it is very inconvenient to check the cause, especially for those where the external unit is located at high altitude. For air conditioning units, the inspection will be more inconvenient

Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0018] The embodiment of the invention discloses a method for judging power-on of an external unit of an air-conditioning unit. figure 1 is a structural block diagram of the air-conditioning unit applied to the method for judging the power-on of the external unit of the air-conditioning unit according to the embodiment of the present invention, figure 2 It is a flow chart of the method for judging the power-on of the external unit of the air-conditioning unit according to the embodiment of the present invention.
[0019] Such as figure 1 As shown, the air conditioner unit includes an internal unit 1 and an external unit 2, the internal unit 1 includes a main power supply of the internal unit and a main control part of the internal unit connected thereto, and the main power supply of ...

The invention discloses an external unit power-on judging method of an air conditioner. The air conditioner comprises an internal unit and an external unit; the internal unit comprises an internal unit main power source and an internal unit master control unit; the external unit comprises an external unit main power source, an external unit master control unit and a driving unit, wherein the master control unit and the driving unit are connected with the external unit main power source. The method comprises the following steps that the external unit main power source is controlled to be powered on; after being powered on, the external unit main power source supplies power to the driving unit and the external unit master control unit; the external unit master control unit communicates with the driving unit, if communicating with the driving unit normally, the external unit master control units determines that the external unit is powered on normally, and if not, determines power-on failure and transmits power-on failure signals. The external unit power-on judging method of the air conditioner saves manual inspection, and the external unit can determine the power-on failure by itself, so that manual inspection costs can be reduced; particularly, for an air conditioner with the external unit arranged overhead, the external unit power-on judging method can avoid inspection at height. Besides, the external unit power-on judging method of the air conditioner can avoid customer complaints due to the problem that the external unit fails in power-on.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a method for judging when an external unit of an air conditioning unit is powered on. Background technique [0002] With the development of frequency conversion technology, frequency conversion air conditioners have become mainstream products, and the control part is relatively complicated, which also increases the number of faults. Some minor problems may have to be checked one by one. For air-conditioning units with low power consumption requirements, the control of disconnecting the main power supply of the external unit in standby will be added to reduce standby power consumption. [0003] There is no method for judging whether the external unit is powered on in the existing air conditioner units. If the air conditioner unit does not start because the external unit is not powered on, it is very inconvenient to check the cause, especially for those where the external unit is lo...
