After adopting said structure, this utility model has the advantage that
This utility model compressor of air conditioner adopts multispeed electric machine to drive, control relatively simple, it is not necessary to special driving controller, it is only necessary to temperature-detecting device, switching device and general controller are set in outside, the adjustment of various rotating speed can be realized, therefore less costly；In addition compare constant speed compressor, owing to the adjustment of multiple rotating speed can be realized, can be prevented effectively from frequently to shut down to temperature and restart the impact to electrical network, and noise is less, power consumption is also less.
As preferably, described controller is the controller that air-conditioning carries.This setting can reduce cost further.
As preferably, described switching device is relay, the number of described relay is equal with the number of speed governing tap, the control end of the primary side of described each relay is electrically connected with the controller respectively, one end of secondary side electrically connects with the live wire of supply terminals or zero line, and the other end electrically connects with each speed governing tap respectively.This arranges simple and reliable, and cost is low, and is beneficial to and automatically controls.
As preferably, described multispeed electric machine is three-speed motor, and described three-speed motor is provided with three speed governing taps.Three-speed motor both can meet user demand, does not too much increase again cost.
