Description
Technical field
The present invention relates to fields of home appliance technology, and in particular to a kind of range hood and its control method.
Background technique
Currently, range hood on the market can generally be equipped with headlamp on kitchen ventilator, light switch is set on panel,
When carrying out culinary art work, user opens light switch and opens headlamp, and after culinary art, user closes light switch
Headlamp is closed.The above process needs the opening and closing operations that user is switched, and the convenience used is bad, and user leaves and forgets
In the case that note is turned off the light, headlamp can then work on power always, consume unnecessary electricity.
In this regard, prior art discloses a kind of kitchen ventilator control method, by kitchen ventilator start extract oil smoke it
Before, by around pyroelectric human body infrared sensor detection kitchen ventilator whether presence of people, and will test result and be sent to micro process
Device, microprocessor control the ON/OFF of headlamp, indicator light and display board according to the testing result;Start to be taken out in kitchen ventilator
After taking oil smoke, by pyroelectric human body infrared sensor detection kitchen ventilator around whether presence of people, and will test result transmission
To microprocessor, microprocessor controls the ON/OFF of headlamp according to the testing result.
Although above scheme can be realized opening and closing automatically for smoke-exhauster illuminating lamp, but there is control precision not
It is good, it may appear that the situation accidentally opened or closed influences user experience.User is in range hood in use, especially at night simultaneously
Evening carries out in use, the headlamp of range hood can have the case where being turned on or off suddenly, and user experience is bad.
Summary of the invention
The main purpose of the present invention is to provide a kind of range hood and its control methods, to solve oil suction in the prior art
Headlamp automatic control precision is bad in smoke machine, the bad problem of user experience.
To achieve the above object, the present invention provides a kind of range hood control methods, comprising:
In the standby mode of range hood, whether it is greater than critical open at a distance from kitchen ventilator main body by sensor senses user
L1 meters of distance are opened, and whether the duration is greater than T1 seconds;
If the distance between user and kitchen ventilator main body are greater than L1 meters or the distance between user and kitchen ventilator main body are small
In L1 meters and the duration is less than T1 second, and the voltage or electric current exported to headlamp is less than N1;
If the distance between user and kitchen ventilator main body are less than L1 meters and the duration is greater than T1 seconds, exported to headlamp
Voltage or electric current be greater than N2;
Wherein, it is less than N1 in the voltage or electric current of headlamp input, the headlamp can not be lighted in closing shape
State, the voltage or electric current of the headlamp input are greater than N2, and the headlamp can be lighted in the open state.
Further, comprising:
In the open state of the headlamp, whether it is less than L2 at a distance from kitchen ventilator main body by sensor senses user
Rice;
If the distance between user and kitchen ventilator main body are less than L2 meters, the voltage or electric current exported to headlamp is greater than or waits
In N3;
Wherein, it is less than L1 meters for described L2 meters, N3 is greater than N2, is more than or equal in the voltage or electric current of headlamp input
N3, the brightness of the headlamp is greater than the voltage of headlamp input or electric current is greater than N2 and is less than the brightness of N3.
Further, comprising:
In the open state of the headlamp, whether it is less than L1 meters at a distance from kitchen ventilator main body by sensor senses user
And whether in lasting reduction;
If user is less than L1 meters at a distance from kitchen ventilator main body and in lasting reduction, the voltage or electricity exported to headlamp
Stream is greater than N2 and is increasing;
If user is less than L3 meters at a distance from kitchen ventilator main body and in lasting reduction, the voltage or electricity exported to headlamp
Stream keeps N4 constant;
Wherein, it is less than L1 meters for L3 meters, N4 is greater than N2.
Further, comprising:
In the open state of the headlamp, it is whether to be greater than L3 at a distance from kitchen ventilator main body by sensor senses user
Rice and in lasting increase;
If user is greater than L3 meters at a distance from kitchen ventilator main body and in lasting increase, the voltage that is exported to headlamp or
Electric current is less than N4 and is constantly reducing;
