The big thickness of layer and region, and make that identical device is presented with like reference characters, thus omission retouches them
It states.
Referring to figs. 1 and 2, according to an embodiment of the invention, providing a kind of method of range hood control.
Specifically, method includes the following steps: periodically detecting range hood during range hood operation
The revolving speed of motor whether be located in abnormal sound section, if the revolving speed of motor is located in abnormal sound section, the revolving speed of motor is adjusted, until motor
Revolving speed be located at outside abnormal sound section.
In the present embodiment, by periodically detecting whether the motor speed of range hood is located in abnormal sound section, thus
The revolving speed of motor is adjusted, is located at its revolving speed outside abnormal sound section, setting in this way can efficiently reduce range hood
Noise improves the use feeling of user.
Wherein, this method is further comprising the steps of: during detecting the revolving speed of motor, the revolving speed of motor is when default
It is interior to be respectively positioned in abnormal sound section, adjust the control signal of the gear of range hood.The accuracy that can be improved adjustment is set in this way,
Avoid the situation that mistuning is whole.Preferably, preset time t, wherein 4s≤t≤6s.
It is the skill of the gear in the detection of range hood during adjusting the control signal of gear of range hood
It is adjusted in art.Setting can be improved the reliability for adjusting motor speed in this way.
Wherein, the revolving speed for adjusting motor includes the control signal for adjusting the gear of motor, and control signal includes pwm signal.
The revolving speed of motor is adjusted the following steps are included: pwm signal is increasedd or decreased.Preferably, the control of the gear of range hood is adjusted
Signal processed includes that pwm signal is increased by 3%, alternatively, pwm signal is reduced 3%.
This method further include: before range hood is installed and used, according to the installation of range hood system and range hood
Mode determines the abnormal sound section and duty ratio corresponding range of range hood, during range hood operation, if the revolving speed of motor
In abnormal sound section, adjustment duty ratio is until the revolving speed of motor is located at outside abnormal sound section.Duty ratio is adjusted the following steps are included: every time
Adjustment duty ratio is a%, wherein a% >=T/n, wherein T is the difference of the duty ratio of abnormal sound section, and n is integer.Preferably, n=
3。
It takes for the bad problem of range hood part speed stage sound quality using the technical solution of the application and keeps away revolving speed
Solution.Since the shell frequency of range hood is identical with the frequency multiplication of electric machine frequency or motor, generates and resonate, or due to
There are the abnormal sounds that error, range hood are generated in certain speed stages in smoke machine assembly or production process, by evading revolving speed
Method, that is, increase or decrease duty ratio to adjust revolving speed, to evade the undesirable speed stage of sound quality.
After the gear of kitchen ventilator reaches certain abnormal sound sections, revolving speed can be adjusted by adjusting duty ratio, to reach rule
Keep away the effect of revolving speed.
Since the shell frequency of range hood is identical with the frequency multiplication of electric machine frequency or motor, resonance is generated, or due to cigarette
There are the abnormal sounds that error, range hood are generated in certain speed stages in machine assembly or production process, by increasing or decreasing
Duty ratio adjusts revolving speed, evading the undesirable speed stage of sound quality i.e. abnormal sound section.
After range hood is stable, the revolving speed of range hood is detected, because the gear of some range hoods is not in its revolving speed
Section, but detect 5s Zhong Houjun and carry out revolving speed if detection still falls within abnormal sound section after revolving speed 5 seconds in abnormal sound section and evade.In
After increasing or decreasing 3%, detection revolving speed 5 seconds on the pwm signal of original gear, detects whether to belong to abnormal sound section again, adjust
3% is increased or decreased on pwm signal after whole again, repeatedly, until revolving speed adjusted not until abnormal sound section.
Preferably, the detection time of revolving speed should be greater than or be equal to 5 seconds, if detection time is too short, during shift position,
It may be stopped in abnormal sound section, cause to judge by accident, so general detection time is greater than 5 seconds when between when detecting.
Preferably, depending on the length for neglecting abnormal sound section greatly of each duty ratio adjustment, general select adjustment 3 times is adjusted to
Except abnormal sound section, corresponding duty ratio can be read according to different blower fan systems and mounting means according to set abnormal sound section
S1 to s2, i.e., percentage a% >=(s2-s1)/n of adjustment duty ratio, n generally take 3 every time.
Preferably, because the actual measurement revolving speed of range hood operation is by the position of installation smoke pipe, the pressure of common flue is opened every time
Revolving speed corresponding to machine duty ratio can be all varied, therefore be reset after shutdown into standby mode duty ratio adjustment amount every time, depending on
Situation readjusts duty ratio.
Preferably, smoke machine switchs to position of transferring the files upwards by position of transferring the files downwards, or switchs to position of transferring the files downwards by position of transferring the files upwards, accounts for
Sky is reset than adjustment amount, and its object is to avoid generating accumulative adjustment amount.
