Problems solved by technology

[0002] Touch buttons are popular because of their advantages such as no mechanical action, no loss, and neat and clean button surfaces, especially in the field of home appliances. However, there is a fatal problem with touch buttons: the cleaning process of the button panel under other unconscious actions In the middle, it is easy to accidentally trigger the touch button. If this problem cannot be solved, the device will malfunction due to false triggering, which may have serious consequences.
But there is no good solution for some more general occasions

Embodiment 1

[0012] Embodiment one: if figure 1 The central position of the center is the "lock / unlock" button (1), and 4 common function buttons (2) are evenly distributed around it. From the area covered by these four function buttons (2), any object (including Human body) will trigger the surrounding function buttons (2) first, and then the "Lock / Unlock" button (1), but a touch vertically approaching from the upper part of the "Lock / Unlock" button can produce a normal touch effect.

[0013] The identification and processing method of the key is as mentioned above, only when the "lock / unlock" is touched and the other keys are not touched, the touch is considered to be a valid touch, and then the timing is started, only if the touch remains for more than the set time (such as 2.5 Seconds), the touch is considered to be valid. If there are other key inputs or if the touch hold time exceeds the maximum allowable value (such as 10 seconds), it is considered to be a false trigger and re-enter...

Embodiment 2

[0016] Embodiment two: figure 2 The central position of the lock is the "lock / unlock" button (1), and 3 common function buttons (2) are evenly distributed around the periphery.

[0017] Other implementation measures are the same as in Embodiment 1.

[0018] Since the three circular buttons surround the "lock / unlock" button with a large air gap, the circular buttons can be arranged in an oval shape, reducing the probability of false triggering.

[0019] The advantage of this solution is that fewer keys are required, but there are more leaky areas around it than the first option, and approaching from the leaky area may cause false triggering, and the preventive effect is slightly inferior to the first option.

Abstract

The invention relates to a multi-touch key false triggering prevention method and structure. According to the method and structure, a locking / unlocking key is set, and common function keys or manuallyadded invisible keys are arranged around the locking / unlocking key. The method comprises the following steps of: when the locking / unlocking key is located in a locking state, considering that the input of the other keys is invalid and only the input of the locking / unlocking key is valid; when the locking / unlocking key is located in an unlocking state, considering that the input of all the keys isvalid; when no keys carry out input for a certain time, automatically entering the locking state or entering the locking state via manual triggering; and if the locking state needs to be released, carrying out touch, keeping locking / unlocking for a certain time and carrying out releasing when the other keys do not carry out input, and if releasing is not carried out after a set time, consideringthat the input is invalid and re-entering into the locking state.

Description

technical field [0001] The invention relates to the field of touch keys, in particular to a method and structure for preventing false triggering of multi-touch keys Background technique [0002] Touch buttons are popular because of their advantages such as no mechanical action, no loss, and neat and clean button surfaces, especially in the field of home appliances. However, there is a fatal problem with touch buttons: the cleaning process of the button panel under other unconscious actions In the process, it is easy to accidentally trigger the touch button. If this problem cannot be solved, the device may malfunction due to false triggering, which may have serious consequences. How to avoid false triggering is a headache for many technicians, and some solutions have been proposed for this purpose: such as pressing certain keys in a specific state at a specific time is invalid, using a key combination recognition method, and so on. But there is no good solution for some more...
