DETAILED DESCRIPTION

[0019] In order to make the skilled in the art better understand the technical scheme of the utility model, the utility model is described in detail below in combination with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.

[0020] As Figure 1The utility model discloses a kind of gesture induction and touch color screen display of range hood, including shell 1 and touch color screen 4, electric control board 2 is provided in the shell 1, display module 3 is provided in the middle part of electric control board 2, and display module 3 cooperates with touch color screen 4, gesture induction module 6 is located in the both sides of display module 3, and gesture induction module 6 and display module 3 are electrically connected with electric control board 2, and the sensing signal generated by two gesture induction module 6 is used to control switch and air extraction gear adjustment, the gesture induction module 6 cooperates time relay.

[0021] The content represented by the sensing signal of the specific gesture induction module 6 in the scheme of the present application is as follows: first, the time relay is timed when the first gesture induction signal is generated, and the signal collection time is generally 10-15, the sensing signal is generated by the left gesture induction module 6 first, and then the sensing signal is generated by the right gesture induction module 6, and no other signal is generated within the timing interval of the time relay, which indicates that the air extraction gear is controlled to be increased by 1, otherwise, the signal is generated by the right gesture induction module 6 first, and then the signal is generated by the left gesture induction module 6, which indicates that the air extraction gear is controlled to be decreased by 1, the sensing signal is generated by the left gesture induction module 6 first, and then the sensing signal is generated by the right gesture induction module 6, and the operation is repeated twice or more within the timing interval, which indicates that the machine is controlled to be turned on, otherwise, the signal is generated by the right gesture induction module 6 first, and then the signal is generated by the left gesture induction module 6, and the operation is repeated twice or more within the timing interval, which indicates that the machine is controlled to be turned off; through the gesture induction and touch color screen display of the range hood of the present application, the display can be operated through the touch color screen during cleaning, or the display can be operated through gestures, and if the display screen is stained with oil stains, the display can be operated through gesture induction without contact.

[0022] As Figures 1-3 shown, the scheme of the present application is further optimized, the first display film 5 is pasted on the touch color screen 4, and the integrated film pressing block 9 is arranged on the left side, the right side and the upper side of the shell 1, the front side of the film pressing block 9 is a pressing block for shielding the edge of the shell 1, the second display film 8 is pasted on the part of the gesture induction area of the first display film 5, and the part corresponding to the second display film 8 of the film pressing block 9 is a separately movable film pressing movable block 11.

[0023] Through the design of the first display film 5 and the second display film 8, the effect of intercepting oil stains can be achieved, and when there are many oil stains, the display can be kept clean by replacing the display film, according to the corresponding situation, the gesture induction area needs to ensure the accuracy of induction, so the requirement for oil stains is higher, the second display film 8 designed separately can handle the stains in this area separately to ensure the precision and stability of gesture induction.

[0024] As Figure 3Further, the first display film 5 is provided with a tapered ring 7 around the gesture sensing area, and the second display film 8 is attached to the tapered ring 7.

[0025] The gesture sensing area is protruded forward relative to other areas of the display screen by the tapered ring 7, which effectively reduces the oil stain attached to the gesture sensing area and improves the gesture sensing accuracy and stability of the gesture sensing area.
