Slowly the mode risen avoids the noise for issuing burst when rotation speed of the fan transient rise, improves the comfort that air conditioner uses.
Detailed description of the invention
Fig. 1 is the control method process principle total figure of air conditioner room unit rotation speed of the fan of the present invention.
Fig. 2 is the sub-step process principle figure of step S2 of the present invention.
Below by way of the drawings and specific embodiments, the invention will be further described:
Specific embodiment
Fig. 1 and 2 show the control flow chart of the method for the present invention, now in conjunction with Fig. 1 and 2 in air conditioner chamber of the present invention
The control method of machine rotation speed of the fan is described in detail, control method of the present invention the following steps are included:
Step S1: judging whether there is revolving speed and rise alteration command, if it is, S2 is entered step, if it is not, then keeping room
The interior existing revolving speed of machine fan.
Step S2: analysis air conditioner function sets and judges whether that revolving speed is needed slowly to rise, if it is, entering step
S3, if it is not, then indoor machine fan revolving speed is climbed to rotating speed of target by existing normal mode.
Step S3: calculating rotational speed difference △ R=rotating speed of target-current rotating speed, and comparison rotational speed difference △ R is determined in corresponding range
Rotation speed of the fan rises change rate t:
1) as △ R < 100rpm, then indoor machine fan revolving speed is climbed to rotating speed of target by existing normal mode, i.e.,
T=existing normal mode rotation speed of the fan rises change rate；
2) as 100rpm≤△ R≤1500rpm, there is 2rpm/s≤t≤300rpm/s, i.e., when 100rpm≤△ R≤
When 1500rpm, rotation speed of the fan rise change rate t can between 2rpm/s~300rpm/s any value；In order to further preferred,
Function can slowly be risen by following several hierarchical subdivisions to advanced optimize rotation speed of the fan:
21) as 100rpm≤△ R≤300rpm, there is 30rpm/s < t≤300rpm/s.
22) as 300rpm < △ R≤600rpm, there is 2rpm/s≤t≤10rpm/s.
23) as 600rpm < △ R≤900rpm, there is 10rpm/s < t≤15rpm/s.
24) as 900rpm < △ R≤1200rpm, there is 15rpm/s < t≤20rpm/s.
25) as 1200rpm < △ R≤1500rpm, there is 20rpm/s < t≤30rpm/s.
It should be noted that the when marquis of rotation speed change will not generate obvious noise as 100rpm≤△ R≤300rpm,
It will not rising at once, it is possible to which by within the scope of the rotational speed difference revolving speed rising change rate value is scheduled on relatively large
Value.
3) as △ R > 1500rpm, there is t=35rpm/s.
S4: indoor machine fan rises change rate t according to the rotation speed of the fan of above-mentioned determination and rises to rotating speed of target.
Further specific, in step s 2, air conditioner function setting includes the slow ascending fashion setting of revolving speed, sleep pattern
Setting, the setting of human body sensing mode, wherein sleep pattern, human body sensing mode are that existing air-conditioned conventional func is no longer superfluous herein
It says, and the slow ascending fashion of revolving speed needs that function choosing is being added in airconditioning control chip and remote controler in air conditioner manufacture
, in this step S2, judge whether that needing revolving speed slowly to rise specifically includes following sub-step, as shown in Figure 2
S21: judging whether to start the slow ascending fashion of revolving speed, if it is, S3 is entered step, if it is not, then entering step
Rapid S22；
S22: judge whether to start sleep pattern, if it is, S3 is entered step, if it is not, then entering step S23；
S23: judge whether to start human body sensing mode, if it is, S24 is entered step, if it is not, then indoor machine fan
Revolving speed is climbed to rotating speed of target by existing normal mode；
S24: judging the size of human activity amount, if it is small, then enters step S3, if it is big, then indoor machine fan
Revolving speed is climbed to rotating speed of target by existing normal mode.
In order to be further described further to control of the invention, now by taking one of air conditioner model as an example: the sky
Adjust parameter as follows:
High revolving speed: 1300rpm；Middle revolving speed: 1020rpm；The slow-speed of revolution: 780rpm；It is mute: when 700rpm air quantity is automatic:
It is changed between 680rpm~900rpm.
1) when i.e. air quantity is automatic, rotation speed of the fan exists: changing between 680rpm and 900rpm, △ R=220 belongs to 100rpm
The range of≤△ R≤300rpm, then the rising change rate of indoor machine fan revolving speed is corresponding are as follows: 30rpm/s < t≤300rpm/s,
That is t can be in any value of the range, it is assumed that t=40rpm/s, that is to say, that revolving speed is since 680rpm, with the speed of 40rpm/s
Until rising to 900rpm；
2), with remote controler from the mute supreme revolving speed of switching: rotational speed difference △ R=1300rpm-700rpm=600rpm belongs to
The range of 300rpm < △ R≤600rpm, then the rising change rate of indoor machine fan revolving speed is corresponding are as follows: and 2rpm/s≤t≤
A wherein value may be selected, it is assumed that t=8rpm/s, that is to say, that revolving speed is since 700rpm, with the revolving speed of 8rpm/s in 10rpm/s
Until rising change rate rises to 1300rpm.
3, the slow-speed of revolution is switched to from mute with remote controler: rotational speed difference △ R=780rpm-700rpm=80rpm < 100rpm, then
Indoor machine fan revolving speed is climbed to rotating speed of target by existing normal mode.
