Specific embodiment
Present invention is further described in detail in the following with reference to the drawings and specific embodiments, it should be understood that described herein Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
In subsequent description, it is only using the suffix for indicating such as " module ", " component " or " unit " of element Be conducive to explanation of the invention, itself there is no a specific meaning.Therefore, " module ", " component " or " unit " can mix Ground uses.
At present for the place of the heavy oil cigarette such as kitchen, air-conditioning needs to carry out permanent wind quantity test after unlatching, to bring good Good wind speed, brings better experience to user.But the debugging of permanent wind amount, it is sometimes necessary to 3 to 6 minutes；And the present invention is just It is the time for shortening the debugging.
Fig. 1 is the flow chart of permanent wind amount adjustment method according to an embodiment of the present invention, as shown in Figure 1, this method include with Lower step:
Step S101 determines the accumulative days running of equipment after opening of device；
Step S102, in the case where accumulative days running is not zero, according to accumulative days running and a preceding permanent wind amount The history data of debugging determines the object run data of this permanent wind amount debugging.
