Description
Technical field
It the utility model is related to a kind of non-contact control device of range hood.
Background technology
Range hood changes the overall situation in kitchen, can take the oil smoke harmful to kitchen environment and human body rapidly away,
Oil smoke is discharged to outdoor, reduces pollution, purifies air, and has gas defence, the effect of explosion-proof safety guarantee.Range hood has turned into
The essential cooking apparatus of Modern Family.Range hood after a long time use, its contact panel or by the upper meeting that compresses switch
Greasy dirt is infected with, now goes operation to make finger dirty, is manipulated in addition when having kitchen tools or very dirty hand in hand, then can pollute tactile
Control panel or by compressing switch.
Patent No. ZL 201520881739.8 (notification number CN205156087U) Chinese patent discloses a kind of oil pumping
Cigarette machine gestural control system, it includes display module, reminding module, lighting module and main control module, apart from induction module and moves
Make induction module, wherein including capacitance sensor and capacitance detecting chips apart from induction module, capacitance sensor is used to sense people
Range information is simultaneously converted into corresponding capacitance by the distance of hand, and capacitance detecting chips are used for the capacitance for detecting capacitance sensor
And the first feedback signal is sent when capacitance reaches predetermined value；Action sensing module is used to detect the gesture of operator and examined
The second feedback signal is exported when measuring predetermined gesture；Main control module can control the start and stop of blower fan according to the first feedback signal,
Main control module controls the rotating speed of blower fan according to the second feedback signal.In this non-contact control mode, action sensing module uses
One group of infrared transmitter and infrared remote receiver judge the gesture of operating personnel, i.e. main control module covers infrared simultaneously according to human hand
The number of transmitter and infrared remote receiver controls rotation speed of fan, when simultaneously human hand covers infrared transmitter and infrared remote receiver
When number is one time, rotation speed of fan is low grade, when simultaneously the number that human hand covers infrared transmitter and infrared remote receiver is secondary
When, rotation speed of fan is middle-grade, when human hand cover simultaneously the number of infrared transmitter and infrared remote receiver for three times when, rotation speed of fan
For top grade, the mode that this unlatching and rotating speed by way of counting to blower fan is controlled is very clumsy, and counts and hold very much
Error-prone (particularly when oil smoke concentration is larger, serious interference, count and be easier to malfunction), so as to cause user to lose patience,
Consumer's Experience is bad.
Application No. CN201510011826.2 (notification number CN104566591A) Chinese patent discloses a kind of oil suction

With some infrared receiver inductors of the extraneous infrared light reflected of detection, some infrared-emitting diodes and some infrared connect
Receive inductor to correspond, infrared light is sent out successively by several infrared-emitting diodes, several infrared receivers pass
Sensor detects infrared luminous intensity when corresponding infrared-emitting diode lights and corresponded to when infrared-emitting diode extinguishes successively
The infrared luminous intensity of background, the infrared luminous intensity Real time identification then detected according to each infrared receiver inductor control gesture；
Further according to control gesture generation control instruction control range hood.This mode, detected according to each infrared receiver inductor
Infrared luminous intensity Real time identification control gesture, then lampblack absorber is controlled according to predetermined gesture, this mode compared with " meter
Number " control mode has larger improvement, is avoided that the inaccurate problem of control that Acquisition Error is brought that counts；It is but dense in oil smoke
Spend it is larger, or when user's height is higher, the part of oil smoke and user's body the reception of infrared light can be interfered (oil smoke and
Human body can reflect or scattered infrared light), its dry resistance can be still poor, therefore non-contact control mode still needs improvement.
