Embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical scheme will be carried out below
Detailed description.Obviously, described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all on the premise of creative work is not made
Other embodiment, belongs to the scope that the present invention is protected.
Fig. 1 is the basic flow chart of the present invention, and the humidifier of control method of the invention application includes two kinds of humidifying modes:
Common humidifying mode and nasal cavity humidifying mode, wherein common humidifying mode refer in the case of normal room temperature and humidity, be
Alleviate the humidifying mode that indoor seasoning uses;Nasal cavity humidifying mode refers to that working as user's nasal cavity feels excessively dry, actively moves close to
After humidifier, humidifying mode that humidifier is used according to the distance of user face and humidifier fog outlet;
As shown in Fig. 2, show a kind of embodiment of humidifier control method provided by the invention.The humidification of the embodiment
Device control method comprises the following steps:
Step S1:Control humidifier enters common humidifying mode;
Step S2:Start the imaging sensor positioned at humidifier fog outlet, obtain user's face profile, calculate contour area
SProfile, when the contour area meets preset condition, start the position detector for being located at fog outlet by the contour area with controlling
Face contour area S is preset in device processedIn advanceCompare, as 80%≤SProfile/SIn advanceWhen≤100%, start the position detection positioned at fog outlet
Device;Work as SProfile/SIn advanceWhen being unsatisfactory for preset condition, humidifier maintains current dehumidification mode;
In step S2 when user's face is close to humidifier fog outlet, imaging sensor can gather facial contour, due to normal
The side face contour area of people is less than positive face contour area, and the increase of the angle with facial orientation sensor, side face profile
The ratio of area and positive face contour area is increasing, therefore, as 80%≤S of satisfactionProfile/SIn advanceWhen≤100%, illustrate user towards
Humidifier fog outlet, it is possible to which there is the demand of moistening nasal cavity;At this time, S3 is entered step.
Step S3:Face and humidifier fog outlet distance D are obtained using position detector, as 10cm≤D≤20cm, control
Device control humidifier processed enters nasal cavity humidifying mode;
When detecting user in step s 2 towards humidifier fog outlet, illustrate that user there may be the need of moistening nasal cavity
Ask, but it could also be possible that in rotary head, it is not intended in see that, to humidifier fog outlet, therefore, it is necessary to sentence by the distance of step S3
Disconnected step, when user's face meets 10cm≤D≤20cm with humidifier outlet distance D, illustrates that face faces humidification at this time
Device fog outlet, and it is close from humidifier fog outlet, then it can be determined that user needs to soak nasal cavity, therefore, controller
Controllable humidifier enters nasal cavity humidifying mode.
In addition, the position detector is infrared human body sensor, belonging positions detector acquisition face and humidification are utilized
The step of device fog outlet distance D, includes:
Infrared detection steps, human body infrared image is obtained using infrared human body sensor;
Analysis On Heat Source step, when heat source temperature is more than or equal to normal human body temperature's lower limit and is less than or equal to normal person's body temperature
When spending upper limit value, the heat source is determined as human body heat source, calculates face and humidifier fog outlet distance D;
Nasal cavity humidifying mode is:Controller adjusts humidifier according to the mapping relations of the distance D and humidifier fog-supplying amount S
Fog outlet area and rotation speed of fan adjustment fog-supplying amount;
Wherein, the mapping relations of fog-supplying amount S and distance D are S=a*D+b, wherein, a, b are constant.
It should be noted that calculating comfortable fog-supplying amount S by formula S=a*D+b, wherein a, b is constant, for example, S=
0.025*D+0.01, unit ml/s, fog-supplying amount increase with the increase of distance D, work as D>During 20cm, stop nasal cavity humidification mould
Formula, is converted to common humidifying mode.It is understood that the value of the parameter such as a, b in above-mentioned formula can be as the case may be
And flexibly set, do not limit the present invention.
It is the conventional technique hand of this area by adjusting humidifier fog outlet area and rotation speed of fan adjustment fog-supplying amount
Section, herein without being expanded on further, those of skill in the art would appreciate that adjustment fog outlet area can adjust the shape of fog
Shape, during nasal cavity humidifying mode, can suitably turn fog outlet area down, increase the mode of rotation speed of fan to be adapted to fog-supplying amount, reach
More comfortable purpose.
Further, include after the step S3:When being unsatisfactory for 10cm≤D≤20cm, humidifier remains current
Dehumidification mode.
Controller can be adjusted according to the infrared fog-supplying amount according to the human body temperature that infrared human body sensor obtains, example
Such as, when human body temperature is excessive, illustrates indoor seasoning, suitably fog-supplying amount can be adjusted, increase fog-supplying amount.
Further, when controller control humidifier enters nasal cavity humidifying mode, prompting is sent, reminds user to enter nose
Chamber humidifying mode.
It is described to prompt for alarm and reminding, voice prompt, one kind of LED light prompting.
