Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
With reference to the accompanying drawing come describe the embodiment of the present invention air conditioner dust accumulation detection method, device and air conditioner.
Fig. 1 is the flow chart of the dust accumulation detection method of air conditioner according to an embodiment of the invention, as shown in Figure 1, should
Dust accumulation detection method includes:

It is run three minutes under low wind file.
S104 judges whether indoor unit wind wheel power of fan is less than other work wind files under the conditions of other work wind files
Set power threshold.
If so, entering step S105；If it is not, return step S101.
In the embodiment of the present invention, under the conditions of other work wind files, the indoor unit wind wheel wind under other work wind files is judged
Whether machine power is less than other work wind files setting power threshold, other work wind files set power threshold and are less than other work wind
Shelves rated power, wherein work wind file is higher, and the difference of corresponding setting power threshold and rated power is bigger, as one kind
Feasible embodiment can run the room obtained after setting time under other work wind files by machine indoors under other work wind files
Interior machine wind wheel fan power judges whether indoor unit runs into the visible S101 step of method of stable state and specifically describes, this
Place repeats no more.
For example, air conditioner includes high wind file, middle wind file, low wind file, work at present wind file is high wind file, then other work wind
Gear is middle wind file, low wind file, and high wind file, middle wind file, low wind file rated power are respectively Peh, Pem, Pel, high wind file, apoplexy
Shelves, setting power threshold is respectively Peh-a, Pem-b, Pel-c under low wind file, wherein and a > b > c > 0 is wind file in acquisition, low
Indoor unit wind wheel power of fan Pim, Pil of wind file, judge whether Pim < Pem-b and Pil < Pel-c.
S105 judges that indoor unit dust accumulation is serious.
In the embodiment of the present invention, if the indoor unit wind wheel power of fan under other work wind files is less than other work wind files
Under setting power threshold, then judge that indoor unit dust accumulation is serious.
S106, control indoor unit are issued for prompting the serious information of indoor unit dust accumulation.
In the embodiment of the present invention, after judging that indoor unit dust accumulation is serious, control indoor unit is issued for prompting indoor unit
The serious information of dust accumulation reminds user to clear up strainer.
S107 continues to execute S101 step after being spaced setting time.
In the embodiment of the present invention, after judging that indoor unit dust accumulation is serious, after being spaced setting time, continues to execute and judge room
Whether interior machine reaches steady operation condition step, that is, continues to execute S101 step, wherein concretely 40000 points of setting time
Clock.
It is exemplified by Table 1 below and above-described embodiment is discussed in detail.
Table 1 blocks up return air area simulation dust accumulation area test result table
Table 1 is that stifled return air area simulates dust accumulation area test result table, after blocking 3/4 return air area, assert dust accumulation
Seriously.Under same voltage conditions, rated motor power: high wind file Peh=54W, middle wind file Pem=38W, low wind file Pel=is remembered
31W, be arranged under high wind file, middle wind file, low wind file set power threshold be respectively Peh-20W=34W, Pem-14W=24W,
Pel-8W=23W, when blocking 3/4 return air area, under high wind file, middle wind file, low wind file power of motor be respectively 31W, 23W,
22W then assert that indoor unit dust accumulation is serious, issues prompt information at this time.
The dust accumulation detection method of the air conditioner proposed according to embodiments of the present invention, judges whether indoor unit reaches steady operation
Condition；If so, judging under work at present wind file, whether indoor unit wind wheel power of fan is less than work at present wind file setting power
