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.
Embodiment one
Fig. 1 is the flow chart of fin clean method according to an embodiment of the present invention, as shown in Figure 1, this method includes following
Step:
Step S101, detection blower fan electric current；
Step S102 judges that whether dirty fin is stifled according to the blower electric current, if so, starting fin automatically cleaning operation.
That is, the embodiment of the present invention only needs to detect that blower electric current, the dirty stifled situation of fin is judged according to blower electric current,
And when determining that blower is dirty stifled, by starting fin automatically cleaning operation, to guarantee effective air agitation of fin, and then improve
The performance and reliability of unit solve the problems, such as in real time effectively clear up fin in the prior art.
When dirty stifled due to fin, in order to reach scheduled air quantity, blower will improve revolving speed, and after improving revolving speed, blower
Electric current can also increase with it, and be based on this, and whether the embodiment of the present invention judges fin by detection blower fan electric current dirty stifled, and in wing
When piece is dirty stifled, starting fin automatically cleaning operation.
When it is implemented, the method for the embodiment of the present invention, before step S101, further includes: when default fin is dirty stifled
Blower current threshold, and judge that by the blower current threshold, whether dirty fin is stifled, wherein wind described in the embodiment of the present invention
Machine current threshold is greater than blower current value when blower operates normally.
Step S102 in the embodiment of the present invention, comprising: judge whether the blower electric current is greater than the blower current threshold,
If it is, entering in next step, otherwise, the blower electric current is continued to test；It is described further to judge that the blower electric current is greater than
Whether the duration of blower current threshold is greater than preset duration threshold, if it is, starting fin automatically cleaning operation,
Otherwise, the blower electric current is continued to test.
In order to improve fin judgment accuracy dirty plugging, the embodiment of the present invention is detecting blower electric current greater than preset wind
After machine current threshold, it is also necessary to which further detection blower fan electric current is greater than the duration of blower current threshold, when the duration
After preset duration threshold, just start the operation of fin automatically cleaning.

Unit operates normally.
In order to preferably understand method of the present invention, below in conjunction with Fig. 2 to method of the present invention
Carry out detailed explanation and illustration:
After blocking up since fin longtime running is dirty, the running current of unit blower be will increase, and pass through the fortune for detecting unit blower
Row electric current, i.e., above-mentioned blower electric current to judge the dirty stifled situation of fin, and clean fin.
Step S201, judge whether air-conditioner set starts, if it is, entering in next step；
Step S202, detection blower fan electric current；
Step S203, judge whether blower electric current Is is greater than preset blower current threshold Ic, if it is, entering step
Otherwise S204 enters step S208；
It is pre- to judge whether blower electric current Is is greater than greater than the duration T s of preset blower current threshold Ic by step S204
If duration threshold Tc otherwise, enter step S208 if it is, entering step S205；
That is, if duration T s of the blower electric current Is greater than preset blower current threshold Ic is greater than default hold
Continuous time threshold Tc, unit enter self-cleaning function；
Step S205, unit shutdown, Dan Kaifeng machine；
Step S206, blower reversion operation, and maintain predetermined time Tf；
Step S207 closes blower；
Step S208, unit operate normally.
On the whole, method described in the embodiment of the present invention, it is only necessary to increase in existing control and blower electric current is held
The detection of continuous runing time, can realize the detection and judgement of stifled situation dirty to fin, so that reaching sky proposes unit automatic implementation
Fin cleaning dirty plugging, reduce because fin it is dirty it is stifled caused by unit performance, reliability reduce, while reducing unit and tieing up after sale
The manpower and material resources of shield.And the practicability and versatility of method of the present invention are very high, and being suitable for all heat exchangers is fin
