Problems solved by technology
This method can prevent false triggering during normal operation, but during use, the user will wipe the touch panel. During the wiping process, the user stays on the touch key for a relatively long time, and can meet the condition that the touch key is triggered. In this process, the situation of false triggering of touch keys is greatly improved, especially for kitchen appliances that are always powered on, such as range hoods, which brings unnecessary troubles to users for cleaning kitchen appliances.

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] The anti-mistouch touch panel in this embodiment can be applied to various electrical appliances with touch panels. The touch panel is described in detail.
[0027] Such as figure 1 As shown, the range hood in this embodiment includes a range hood body, a controller disposed inside the range hood, and an anti-mistouch touch panel disposed on the range hood body. The anti-mistouch touch panel is arranged on the front panel of the range hood body.
[0028] The anti-mistouch touch panel includes a panel 1, a touch key 2 embedded in the panel 1, and at least two brightness sensors 3, and each touch key 2 and each brightness sensor 3 are electrically connected to the controller.
[0029] The brightness sensor 3 is located at the periphery of the touch key 2, so the quantity of the brightness sensor 3 is specifically determined according t...

The invention relates to a mistake touch preventing touch panel which comprises a panel and touch keys arranged in the panel in an embedded manner. The mistake touch preventing touch panel is characterized by further comprising at least two brightness sensors arranged in the panel in an embedded manner, and the brightness sensors are located on the periphery of the touch keys. The invention relates to an exhaust hood which comprises an exhaust hood body, a controller arranged in the exhaust hood and the mistake touch preventing touch panel arranged on the exhaust hood body. All the brightnesssensors and the touch keys in the mistake touch preventing touch panel are electrically connected with the controller. The invention further relates to a mistake touch preventing method of the touch panel. The mistake touch preventing method is characterized in that after one brightness sensor detects a shielding signal, the touch keys are controlled to be locked for short time, and after more than one brightness sensor detects the shielding signal, the touch keys are controlled to be locked for a long time. By means of the mistake touch preventing touch panel, the exhaust hood and the mistaketouch preventing method of the touch panel, the mistake triggering probability in the wiping and cleaning process can be lowered, and the cleaning convenience is greatly improved.
Description
technical field [0001] The invention relates to an anti-mistouch touch panel, and also relates to a touch panel with the anti-mistouch, and also relates to an anti-touch method for the touch panel. Background technique [0002] Most of the existing electric appliances in the market use touch buttons, which are easy to operate and easy to clean. However, due to the principle characteristics of the touch button itself, there is a situation of false triggering, which greatly affects the user experience. [0003] The announcement number is CN15361707 (application number is 201410441525.9) Chinese invention patent "Electric Cooker and Its Control Method", in which the disclosed control method is to detect the capacitance value of the touch button in real time after the electric cooker is powered on; Calculate the difference DF1 between the capacitance value of the touch key and the current value on the first change baseline of the touch key during a preset time, and calculate th...
