Embodiment Construction

[0012] The specific implementation of the present invention will be further described in detail below in conjunction with a section of washing machine remote control key input program.

[0013] Such as figure 2 As shown in , there are four control keys on the control panel of the washing machine. That is, the four keys [On / Off], [Mode+], [Mode-], and [Start / Stop]. The combined functions of each key are as follows:

[0014] 1. [On / Off]

[0015] If you press this button, the washing machine starts to run. If the washing machine is running, when this button is pressed, the washing machine will pause, and pressing it again will restart the washing machine.

[0016] 2. Child lock button

[0017] The Child Lock key is a hidden key. If you press the [MODE+] and [MODE-] buttons at the same time for more than 2 seconds, the child lock function will be triggered. The child lock function can only be triggered in two states, when the washing machine is turned off and when it is ru...

Abstract

This invention discloses an anti-interference control method of household appliance input, which comprises key input phase, key scanning module phase, anti-interference control module phase, function phase and key process close phase. This invention can clearly distinguish the key input and noise interference, which does not trigger when there is interference and triggers when there is real input. Furthermore, the user also adjusts the reaction speed of the key according to user needs and habits.

Description

technical field [0001] The invention relates to an anti-interference control of a household electrical appliance and its remote control key input, in particular to an anti-interference control method for the key input of a household electrical appliance. Background technique [0002] The existing key input control technology: directly enters the key function processing stage after the key scanning stage ends. Such as figure 1 As shown, its control program is: after the key is input, enter the key scanning module to determine which key is input, enter the key function function processing after the key scanning is completed, perform different functions according to the key input, and then wait for the key input again. Its control program does not have a special processing program against noise. Therefore, the anti-interference ability of home appliances is relatively poor. Under severe conditions such as lightning strikes, disturbances will be recognized as normal key input...
