It should be noted that description and claims of this specification and term " first " in above-mentioned attached drawing, " Two " etc. be to be used to distinguish similar objects, without being used to describe a particular order or precedence order.
Embodiment 1
The embodiment of the invention provides a kind of starting methods of air-conditioning self-cleaning function.Fig. 1 is that the embodiment of the present invention is hollow The flow chart of the starting method of self-cleaning function is adjusted, as shown in Figure 1, this method comprises:
Step S101 obtains the first current value of operation of air conditioner in air conditioner refrigerating operational process, wherein current value is Complete machine current value;
Step S103 determines whether to start the certainly clear of air-conditioning according to the difference of the standard current value of the first current value and air-conditioning Clean function.
By the above method, in air conditioner refrigerating operational process, the first current value of the operation of air conditioner is obtained, wherein The current value of acquisition is complete machine current value;Determine whether that starting is empty according to the difference of the standard current value of the first current value and air-conditioning The self-cleaning function of tune.Solve the problems, such as in the prior art air-conditioning can not automatic trigger cleaning function so that air-conditioning was using Cheng Zhong can automatically decide whether triggering self-cleaning function according to the variation of current value, improve the working efficiency of air-conditioning, improve User experience.
It should be noted that the complete machine current value current value obtained is operation of air conditioner herein when, it can be by current detecting Sensor measures.Alternatively, it is also possible to reach identical purpose by detection complete machine power or Energy Efficiency Ratio.Wherein, complete machine power With the relationship of complete machine electric current are as follows: complete machine power W=complete machine voltage U* complete machine electric current I;The relationship of Energy Efficiency Ratio and complete machine electric current: efficiency Than APF=refrigerating capacity/(complete machine voltage U* complete machine electric current I).By above-mentioned two formula it is found that either complete machine power still can Ratio is imitated, it can be with indirect gain complete machine current value, thus according to the complete machine current value and air-conditioning that are obtained during operation of air conditioner Standard current value difference determine whether start air-conditioning self-cleaning function.
