Touch key control method and control device and household appliance

Abstract

The invention discloses a touch key control method and control device and a household appliance, and the control method comprises the steps: obtaining a real-time touch value and the number of detection times of a touch key in preset time; when the number of times that the real-time touch value exceeds the preset range is larger than the preset number of times, judging that radio frequency conduction interference exists in the touch key; the reference value being increased from the initial reference value to the first reference value, and after interference disappears, adjusting the reference value back to the initial reference value. According to the control method of the touch key, whether radio frequency conduction interference exists at present or not is judged by monitoring the fluctuation condition of the real-time touch value of the touch key, the reference value of the touch key is synchronously adjusted, when the radio frequency conduction interference is detected, the reference value of the touch key is increased, and when it is detected that the interference disappears, the reference value is called back. The user experience of the touch key is improved, the touch key is prevented from jumping when being interfered by radio frequency conduction, and the safety is improved.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, in particular to a control method for a touch key, a control device and a household electrical appliance. Background technique [0002] Since the experience of using touch buttons is better than that of micro switches, more and more household appliances use touch buttons. The touch button is not like a micro switch that generates signals mechanically, but by an analog circuit, which makes the touch button vulnerable to interference and key skipping. While high-sensitivity keys bring a good touch experience, they are more likely to cause key jumps due to external interference; low-sensitivity keys have a lower risk of key jumps, but the keys may not respond normally. Contents of the invention [0003] In order to solve the technical problem that the existing touch keys mentioned in the background technology cannot take into account high sensitivity and high anti-...

Problems solved by technology

[0003] In order to solve the technical problem that the existing touch keys mentioned in the background technology cannot take into account high sensitivity and high anti-interference ability at the same time, the present invention provides a touch key control method, a control device and a household appliance. When radio frequency conduction interference occurs, increase the reference value of the touch key, and when the interference disappears, return to the initial reference value, effectively preventing the touch key from jumping due to radio frequency conduction interference, and improving security
