An intelligent range hood

Abstract

The invention relates to an intelligent range hood, which includes a body, a fan assembly, a smoke baffle, a control board, and three sets of gesture detection sensors, all of which are electrically connected to the control board, and is characterized in that: the body passes through a first The lifting mechanism is fixed on the wall, or / and, the smoke baffle is fixed on the body through the second lifting mechanism, and the first lifting mechanism or / and the second lifting mechanism are also electrically connected to the control panel, so The control board calculates the radius of curvature and the center of circle of the user's hand by detecting the signals of three groups of gesture detection sensors, and then obtains the body height matched with the user's height, thereby controlling the first lifting mechanism or / and the second lifting mechanism. Compared with the prior art, the present invention has the advantage that it does not need additional hardware such as fingerprints and camera detection, and uses the detection signal of the existing gesture detection sensor to adjust the height of the body or the height of the smoke baffle to meet the needs of different users. Comfortable, high degree of automation.

Description

technical field [0001] The invention relates to an intelligent range hood. Background technique [0002] The range hood is a necessary household appliance for sucking and exhausting the range hood when people cook daily. In order to prevent the user from directly operating the buttons or touch panel on the body, to prevent the buttons or touch panel from being contaminated with oil, or to avoid manipulating the buttons or touch panel on the body when there are kitchen utensils in the hands or the hands are dirty, polluting the buttons or touch panel panel. At present, there are range hoods with infrared gesture control function designed on the basis of infrared sending and receiving principles on the market. Gestures are used to realize the operation of some functions of the range hood, such as the function of waving to stir-fry, waving to increase the air volume gear, Wave hand switch machine and other functions. For example, in the Chinese patent application with the app...

Problems solved by technology

However, after this type of range hood is installed, the height is fixed and cannot be adjusted, and there may be many people in the family who participate in cooking activities alternately at different times, and the heights of different family members often have large differences. There will be situations where the smoke baffle blocks the line of sight or the height of the switch is too high to be inconvenient to operate. It cannot adjust its height according to the height of the specific user. The degree of intelligence is low and still needs further improvement.
