Description
Technical field
The present invention relates to smoke exhaust ventilator technical field, range hood and its control more particularly to gesture control function
Method.
Background technology
Existing lampblack absorber, the air quantity regulation of range hood can only be completed by hand touch key-press.
In actual use, some mechanical keys susceptible under oil smoke, this adverse circumstances of vapor, and these
The regulative mode of contact used in cooking process when having greasy dirt on hand or having water it is also inconvenient, be easily caused by
Key fails.
For drawbacks described above, although there are some range hood manufacturers to be improved, but still there is many not
Foot.
For example, Patent document number 205536035U, patent name are《A kind of range hood for sensing gesture》, patent public affairs
The range hood that controller is provided with a kind of cigarette machine body is opened, nationality is sent signal and detected and is blocked and the letter that turns back by controller
Number adjust rotation speed of fan, but the technology mainly controls range hood by user's number of times of waving, and in actual applications, again
Can not possibly so user for open a range hood function can upper ten hands several times, it is less therefore, it is possible to the function of realization.
And for example, Patent document number 204593508U, patent name are《A kind of range hood with infrared sensing switch》,
The patent utilization one group of infrared ray sensor corresponding with mechanical button replaces mechanical button, blocks infrared by operator
Line produces the function that correlation is triggered after reflection；However, in actual use, due to there is multiple RF transmitters and reception
Device, and the control panel of range hood is relatively small, and user often triggers after the generation reflection of some infrared ray is blocked
Multiple infrared receivers, cause the confusion of control system, therefore practical effect is excessively poor.
For another example, Patent document number 104566591A, name of patent application《A kind of Untouched control side of range hood
Method》, a kind of range hood for including multigroup one-to-one infrared opposite-radiation device is the patent application disclose, nationality is by using red
Want to solve the mode penetrated diffusion and refraction problems of the signal in the environment of oil smoke and vapor is mixed outside, but this knot
Structure needs the two rows mutually relative infrared emitting and sampling apparatus penetrated, and user must be between the infrared facility to penetrating
Operation could realize the control to range hood, and this structure not only causes extractor hood structure complicated, and Consumer's Experience is also paid no attention to
Think.
Accordingly, it would be desirable to which the control mode to existing range hood is improved, to overcome the defect of prior art.
The content of the invention
In view of the drawbacks described above of prior art, the present invention provides range hood and its control with gesture control function
Method, the first purpose of realization be nationality by increasing a gesture control module, by being sampled to the gesture that user makes,
The reflected light change produced when acting is converted into electric signal, contactless regulating air volume is realized, existing skill is overcome with this
The defect of art.
To achieve the above object, the invention discloses the range hood with gesture control function, including lampblack absorber main body,
Gesture control module.Wherein, the gesture control module is connected with the control module of the lampblack absorber main body, the control module
The user that nationality is gathered by the gesture control module does the operation that the gesture information sold controls the lampblack absorber main body；It is described
Gesture control module includes a sampling end, and minimum two signal transmitting terminals；The signal of each signal transmitting terminal transmitting
The reflected signal formed after the gesture reflection that nationality is made by user is gathered by the sampling end, and forms the gesture letter
Breath.
It is preferred that, each signal transmitting terminal transmitting is infrared ray.
It is preferred that, the ultrared wavelength of each signal transmitting terminal transmitting is differed.
It is preferred that, the front of the sampling end and the signal transmitting terminal is provided with transparent transmission region, the sampling end,
And the back side of the signal transmitting terminal and side are provided with for passing through infrared light, and prevent the filter coating of visible ray.
The invention also discloses the control method for the above-mentioned range hood with gesture control function, step is as follows：
A. the gesture control module starts, all outside transmission signals of signal transmitting terminal, while the sampling end
It is output as not collecting the reflected signal, confirms not to be blocked in front of the gesture control module, system normally starts；
B. the reflected signal that the sampling end record is each collected, by some reflected signal arrangement form numbers
According to chain, the Data-Link records all reflected signals and interval time in connecting；
C. the sampling end is contrasted the data in the Data-Link and preset value, when in the Data-Link occur with
During the preset value identical data paragraph, the data segment is shaved one's head and delivers to the control module, the control module according to
Corresponding function of the data paragraph in the preset value, control smoke exhaust ventilator work.
It is preferred that, in the step a, if the sampling end has been output as reflected signal, alarm is sent, by user
Confirm after not being blocked in front of the gesture control module, continuing subsequent step.
It is preferred that, the sampling end is infrared ray sampling end, and it is ultrared that the sampling end both sides are respectively equipped with a transmitting
The signal transmitting terminal, and positioned at the sampling end both sides the signal transmitting terminal launch the ultrared wavelength not
Together；
In the step c, operated in the lampblack absorber under air quantity shelves state, the data paragraph is included described in two
Reflected signal, first reflected signal is the signal of the signal transmitting terminal on the left of the sampling end, described in second
When reflected signal is the signal of the signal transmitting terminal on the right side of the sampling end, corresponding function in the preset value is by institute
State the air quantity increase of lampblack absorber；Conversely, then the corresponding function in the preset value is that the air quantity increase and decrease of the lampblack absorber is small.
It is preferred that, when the lampblack absorber is operated under other states, the data paragraph includes two reflected signals, the
First, it is described pre- when reflected signal described in second is respectively the signal of the signal transmitting terminal of the sampling end arranged on left and right sides
If the corresponding function in value is to adjust the lampblack absorber to the most high-grade operation of air quantity shelves.
It is preferred that, the sampling end, the coverage of the signal transmitting terminal are less than 18CM, and the hand of the user is drawn
The speed for crossing two signal transmitting terminals is more than 0.3m/s.
It is preferred that, it is spaced minimum 2s between the every two changes lampblack absorber working condition of control module.
Beneficial effects of the present invention：
Nationality of the present invention in existing smoke exhaust ventilator control module by increasing a gesture control module, by user
The gesture made carries out sampling run-length encoding, and the reflected light change produced when acting is converted into electric signal, realized contactless
Regulating air volume, the defect of prior art is overcome with this.
During using the present invention, when having water on hand or having greasy dirt, regulation air quantity is unaffected, will not cause air quantity button
Failure；High-speed response can be realized, is quick on the draw, it is reliable；Infrared penetration is strong, in the severe bar such as oil smoke, vapor
It is barely affected under part.
The technique effect of the design of the present invention, concrete structure and generation is described further below with reference to accompanying drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
