According to the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will be brighter
The above and other objects, advantages and features of the present invention.
Detailed description of the invention
Some specific embodiments of the present invention is described in detail by way of example and not limitation with reference to the accompanying drawings hereinafter.
Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that these
What attached drawing was not necessarily drawn to scale.In attached drawing:
Fig. 1 is the schematic flow chart of the control method of air cleaning unit according to an embodiment of the invention.
Specific embodiment
Fig. 1 is the schematic flow chart of the control method of air cleaning unit according to an embodiment of the invention.Such as Fig. 1
Shown, the embodiment of the invention provides a kind of control methods of air cleaning unit.Air cleaning unit may include air outlet, mistake
Filter module, air supply module, air volume test module and noise measuring module.Air supply module is configured to promote to pass the gas through filter module mistake
Air outlet is flowed to after filter.Air volume test module is configured to the air quantity at detection air outlet.It is empty that noise measuring module is configured to detection
The noise that air purifying apparatus generates.Filtering module is preferably filter screen, and air supply module is preferably blower.Wherein, air cleaning fills
The control method set can include:
Using the air quantity at air volume test module detection air outlet, airflow value is obtained；And it is examined using noise measuring module
The noise that air cleaning unit generates is surveyed, level of noise is obtained.
Air supply module is controlled according to the airflow value and first object airflow value, so that the air quantity at the air outlet is kept
At the first object airflow value, until the level of noise is greater than the target noise value.That is, making an uproar in level of noise greater than target
Before value, air supply module is controlled according to first object airflow value permanent wind amount.
After level of noise is greater than target noise value, air supply module is controlled according to level of noise and target noise value, so that air
Whether the noise that purification device generates is maintained at target noise value, and judge airflow value less than the second target air volume value；If wind
Magnitude then judges that filtering module loses filtering function less than the second target air volume value.If airflow value is greater than or equal to the second target
Airflow value can make air cleaning unit work on, until airflow value less than the second target air volume value, judges that filtering module loses
Filtering function.Further, air supply module is controlled using PID controller.
That is, air cleaning unit measures electrical power and the revolving speed of blower to be controlled after booting, PID adjusts wind
Machine revolving speed meets permanent wind amount, wherein level of noise is necessarily less than equal to target noise value while meeting permanent wind amount.When meeting permanent wind
When amount, when noise figure is greater than target noise value, into next control logic, and a logic is not returned again to.At this point, can be by target
Noise figure carries out PID adjusting as control target, adjusts rotation speed of fan to meet noise of equipment value, judges that airflow value is at this time
It is no less than the second target air volume value, the second target air volume value can be the minimum air quantity for meeting clean-up effect.If airflow value is less than
Second target air volume value, it is believed that filtering module loses filtering function, need to carry out screen replacing.
Inventors discovered through research that with the use of air cleaning unit, if constantly protected by improving revolving speed
Permanent wind amount is demonstrate,proved, the noise of air cleaning unit is increasing, and after increasing to a certain extent, will affect the life and work of user.
Therefore inventors herein proposing makes air before noise reaches goal-selling level of noise according to the work that level of noise controls blower
Purification device works according to the permanent wind amount of first object airflow value, after level of noise reaches goal-selling level of noise, makes air
Purification device works according to permanent level of noise, to make the noise of air cleaning unit no longer increase and make as far as possible when noise is higher
Air output is bigger, keeps comfortable living and working environment as much as possible.Control method i.e. proposed by the present invention guarantees air
Meet noise objective while the air quantity of purification device again to meet the comfort requirement of air cleaning unit.In order to improve inspection
The accuracy of survey, can be used multiple detection modules while detection is averaged, and also the desirable multiple numerical value continuously detected carry out flat
It calculates and obtains.
In some embodiments of the invention, first object airflow value and the second target air volume are determined according to room area
Value.That is Q=KS, K are multiple, and S is room area.Before first powering on, room area signal is received.First object airflow value is
13 to 17 times of room area, preferably 15 times.Ratio between first object airflow value and the second target air volume value be 1.5 to
2.1.Second target air volume value is preferably 8 times of room area.Target noise value can be 43dB to 48dB, preferably 45dB,
48dB.Second target air volume can be the minimum air quantity for meeting clean-up effect.
