Problems solved by technology

[0002] At present, there are three major defects in the capacitive sensing touch control switch used in the range hood on the market: 1. It is vulnerable to strong electromagnetic interference and causes malfunction; 2. When there is water mist on the operation panel of the range hood, it cannot work normally; 3. If the use time is a little longer, oil stains will often penetrate between the switch sensing electrode surface and the operation panel, and the touch will become insensitive due to the change of the medium

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0020] Such as Figure 1 to Figure 4 As shown, according to an embodiment of the light-controlled touch key operation provided by the present invention, it includes a casing 1, a control panel 2 arranged on the casing, and a control panel connected to the control panel 2. circuit, the control panel 2 is provided with a function key 3, and the inner surface of the control panel 2 is provided with a photosensitive element corresponding to the function key 3, and the photosensitive element senses the change of the light environment on the function key. Corresponding control commands are output to the control circuit, and the range hood provided by the present invention uses photosensitive elements to sense the light environment changes at the function keys to realize the control of the range hood, which makes up for some shortcomings in the performance of the current cap...

Abstract

The present invention provides a light-operated touching-type keying operation-based range hood, which comprises a shell, a control panel arranged on the shell, and a control circuit connected with the control panel. The control panel is provided thereon with function keys. The range hood is characterized in that the inner surface of the control panel is provided with a light-sensitive element corresponding to the function key. The light-sensitive elements output a corresponding control instruction to the control circuit through sensing the variation of the luminous environment of the function keys. The light-operated touching-type keying operation-based range hood is good in resistance to strong electromagnetic interference, water-repellent and oil-repellent. Meanwhile, the surface of an operation keyboard is easy to clean. By means of the above light-operated touching-type key, the defects of conventional capacitance sensing type touch keys are overcome. The above range hood can run reliably in strong-electromagnetic environments with water steams and oil stains, and is longer in service life and wider in application range.

Description

technical field [0001] The invention relates to a light-controlled and touch-type key-operated range hood. Background technique [0002] At present, there are three major defects in the capacitive sensing touch control switch used in the range hood on the market: 1. It is vulnerable to strong electromagnetic interference and causes malfunction; 2. When there is water mist on the operation panel of the range hood, it cannot work normally; 3. After a long time of use, oil stains tend to penetrate between the switch sensing electrode surface and the operation panel, and the touch becomes insensitive due to the change of the medium. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a range hood operated by light-controlled touch keys. [0004] According to the main technical scheme adopted by the range hood operated by light-controlled touch-type keying p...
