[0028] In order to make the personnel in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0029] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or a sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0030] According to the embodiments of the present application, a touch key control method embodiment is provided. It should be noted that the steps shown in the flow chart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0031] As shown in Figure 1 , the method comprises the following steps:

[0032] Step S101, based on the time characteristics of the capacitance detection value of the touch key, the key anti-interference processing is performed, or based on the environmental characteristics of the touch key, the key anti-interference processing is performed.

[0033] In an embodiment, after a user contacts a touch key, the capacitance value of the touch key changes, so that the capacitance detection value changes. The capacitance detection value refers to the detection value of each touch key obtained by detecting the capacitance value of each touch key.

[0034] The time feature of the capacitance detection value refers to the time related to the capacitance detection value, for example, the duration that the capacitance detection value is maintained in a certain interval, for example, the duration that the capacitance detection value exceeds a certain threshold, or for example, the time required for the capacitance detection value to reach a certain threshold. The embodiment is not limited in this regard.

[0035] The environmental feature refers to the environment related to the touch key, for example, the temperature of the touch key, or the temperature in the space where the touch key is located, and the like. The embodiment is not limited in this regard.

[0036] In an embodiment, the key anti-interference processing is used to perform anti-interference processing on the touch key to prevent the touch key from malfunctioning due to temperature and causing false triggering, and to prevent the false triggering touch key from affecting the triggering of other normal touch keys.

[0037] Step S102, after the key anti-interference processing, triggering a corresponding action in response to the trigger signal of the touch key.

[0038] After performing the key anti-interference processing, if a touch key is triggered, i.e., a trigger signal is generated, the action of the corresponding touch key is triggered.

[0039] According to the environmental feature of the touch key or the time feature of the capacitance detection value, the corresponding key anti-interference processing is adopted. Through the key anti-interference processing, it is helpful to avoid false triggering or failure to trigger normally due to damage or malfunction of the touch key, and improve the control effect of the touch key.

[0040] In another embodiment of the present application, the touch key is arranged on a clothes treatment apparatus, and the clothes treatment apparatus has a temperature rising function.

[0041] For ease of understanding, for example, for a clothes treatment apparatus with a drying function, the clothes treatment apparatus heats the airflow to dry the clothes by using hot airflow when drying. During the process of heating the airflow, the clothes treatment apparatus is in the temperature rising stage, and the corresponding temperature rising function is performed.

[0042] In another embodiment of the present application, the key anti-interference processing based on the environmental feature of the touch key includes:

[0043] If the capacitance detection value of any one touch key exceeds the corresponding capacitance threshold value and the capacitance detection value of at least one touch key other than the any one touch key also exceeds the corresponding capacitance threshold value in the temperature rising stage of the clothes treatment apparatus, the any one touch key and the at least one touch key are not effective.

[0044] In an embodiment, the temperature rising stage of the clothes treatment apparatus can be that the clothes treatment apparatus performs a drying function, and the airflow is heated, or the clothes treatment apparatus performs a care function, and the clothes are heated, which is not limited in the embodiment.

[0045] In an embodiment, when the capacitance detection value of the touch key exceeds the corresponding capacitance threshold value, it is proved that the touch key is in a triggered state. The capacitance threshold value corresponding to each touch key can be the same or different, which is not limited in the embodiment.

[0046] Through the above steps, the number of triggered touch keys is combined with the stage (i.e. the environmental feature) of the clothes treatment apparatus to determine whether the touch key failure occurs, and the key anti-interference processing is performed by controlling all triggered touch keys to be ineffective, which helps to reduce the probability of touch key error triggering and improve the control effect of the touch key.

[0047] In another embodiment of the present application, the key anti-interference processing based on the environmental feature of the touch key further includes:

[0048] The key chip is reset, and the capacitance detection value of the touch key is detected again.

[0049] In an embodiment, the key chip is reset, and the capacitance detection value of each touch key is zeroed or reduced.

[0050] Through the above steps, since no capacitance detection value of the touch key reaches the corresponding preset capacitance threshold value, it is proved that the user does not touch each touch key. At this time, if the capacitance detection value of the touch key gradually increases, it is proved that the touch key may be damaged or fail. The key chip is reset, so that the capacitance detection value of the damaged or failed touch key is not easy to reach the corresponding preset capacitance threshold value, thereby reducing the probability of the damaged or failed touch key being triggered and not easily affecting the use of other keys.

[0051] In another embodiment of the present application, after the key anti-interference processing, a corresponding action is triggered in response to the trigger signal of the touch key, including:

[0052] After the key anti-interference processing, when the re-detected touch key is triggered and the effective condition is met, the function flow corresponding to the triggered touch key is executed.

[0053] It should be noted that each key has a corresponding function flow, for example, for the washing key on the washing machine, the corresponding is the washing flow, the user triggers and makes the washing key effective, the washing machine executes the pre-set washing flow. For example, for the shutdown key on the washing machine, the corresponding is the shutdown flow, the user triggers and makes the shutdown key effective, the washing machine shuts down.

[0054] For further understanding, as shown in Figure 2 For example, for the washing machine, there are display operation panel 1, display area 2 and key touch area 3, and the key touch area 3 includes washing key, rinsing key, dewatering key, drying key, starting key and switching key. The user triggers the switching key, the starting key and the washing key in turn, so that the washing machine executes the washing flow.

[0055] In another embodiment of the present application, the method further comprises:

[0056] In the heating stage of the clothes processing equipment, the priority of the touch key of the clothes processing equipment is adjusted to be the same, and the touch key of the clothes processing equipment includes the any touch key and the at least one touch key.

[0057] It should be noted that when two keys with the same priority are triggered at the same time, both keys are not effective by default. Therefore, setting the priority of the triggered multiple touch keys to be the same will make the triggered multiple touch keys not effective, reducing the probability of changing the function flow due to key damage or malfunction or accidental touch.

[0058] In another embodiment of the present application, the anti-interference processing of the key based on the time characteristics of the capacitance detection value of the touch key comprises:

[0059] If the capacitance detection value of the touch key is within a preset fluctuation range less than the capacitance threshold and the duration satisfies the time threshold, the key chip is reset.

[0060] Through the above steps, the capacitance detection value of the touch key is less than the capacitance threshold, but is in the fluctuation range for a long time, proving that the touch key is damaged or malfunctioning. At this time, the key chip is reset, so that the capacitance detection value of the damaged or malfunctioning touch key is reduced or zeroed, making it easy to detect other normal touch keys triggered by the user, and the touch keys triggered by the user are effective, so that the damage or malfunction of the touch key does not easily affect the normal triggering of other touch keys by the user, improving the control effect of the touch key.

[0061] In another embodiment of the present application, the anti-interference processing of the key based on the environmental characteristics of the touch key comprises:

[0062] In the temperature rising stage of the clothes treatment device, and the air inlet temperature meets the preset first temperature threshold, the trigger sensitivity of the trigger button is reduced.

[0063] For the convenience of understanding, as Figure 3 shown, taking a washing machine as an example, it is judged whether to enter the drying temperature rising stage, if it is the drying temperature rising stage, it is judged whether the air inlet temperature is between the first temperature threshold T1, i.e. 65-80 degrees Celsius, if it is not the drying temperature rising stage, it is re-executed whether to enter the drying temperature rising stage.

[0064] If the air inlet temperature is between 65-80 degrees Celsius, the trigger sensitivity of part or all of the buttons is reduced, and the trigger sensitivity of the buttons in the high temperature area is reduced more than that in the low temperature area.

[0065] If the air inlet temperature is not between 65-80 degrees Celsius, it is re-executed whether the air inlet temperature is between the first temperature threshold T1, i.e. 65-80 degrees Celsius.

[0066] After reducing the trigger sensitivity of the button, it is judged whether to enter the drying temperature falling stage. If it is to enter the drying temperature falling stage, it is judged whether the air inlet temperature is less than or equal to the second temperature threshold T2, i.e. 65 degrees Celsius.

[0067] If the air inlet temperature is between the second temperature threshold T2, i.e. less than or equal to 65 degrees Celsius, the trigger sensitivity of all buttons is restored to the original state.

[0068] If the air inlet temperature is not between the second temperature threshold T2, i.e. less than or equal to 65 degrees Celsius, it is re-executed whether the air inlet temperature is between the second temperature threshold T2, i.e. less than or equal to 65 degrees Celsius.

[0069] For the convenience of understanding the scheme, as Figure 4 shown, taking a washing machine as an example, after the control method starts to execute, it is judged whether the capacitance value of a certain button is greater than or equal to the trigger threshold B, if not, it is proved to be in the stage before the button is triggered, it is judged whether the capacitance value of the button is greater than or equal to the set threshold A, if less than the set threshold A, it returns to the step of judging whether the capacitance value of a certain button is greater than or equal to the trigger threshold B; if greater than or equal to the set threshold A, it is judged whether the capacitance value of a certain button is greater than or equal to the set threshold A and less than the trigger threshold B for a duration t; if the duration t has been continued, the button chip is reset and the capacitance value is re-detected; if the duration t has not been continued, it returns to the step of judging whether the capacitance value of a certain button is greater than or equal to the trigger threshold B.

[0070] If the capacitance value of the key is greater than or equal to the trigger threshold B, it is proved that it is in the stage after the key is triggered, whether the switch key (i.e. the target key) and other single or multiple keys are triggered is judged, if the switch key and other single or multiple keys are not triggered, the current switch key priority (the highest) is maintained to perform normal key control flow identification and control; if the switch key and other single or multiple keys are triggered, whether to enter the drying temperature rising stage is judged.

[0071] If the drying temperature rising stage is not entered, the priority of the switch key is adjusted to the highest.

[0072] If the drying temperature rising stage is entered, the priority of the switch key is adjusted to be consistent with the priority of other keys; and the key chip is reset, and whether the switch key and other single or multiple keys are triggered is detected again.

[0073] If the switch key and other single or multiple keys are not triggered again, it is returned to the step of judging whether the capacitance value of the key is greater than or equal to the trigger threshold B.

[0074] If the switch key and other single or multiple keys are triggered again, the priority of the switch key is adjusted to the highest, and whether the switch key is triggered for 2 seconds is judged.

[0075] If the switch key is triggered for 2 seconds, the shutdown state is entered, otherwise it is returned to the step of judging whether the capacitance value of the key is greater than or equal to the trigger threshold B.

[0076] Through the above example, before the key is triggered, the key with the capacitance cumulative value between A and B is reset, and the capacitance cumulative value of each key is detected again, so that each key is not easy to be triggered by mistake before being triggered by the user, and is not easy to be triggered due to damage or failure.

[0077] After the key is triggered, only the temperature rising stage is judged, so that the switch key does not take effect at the first time of triggering, preventing the switch key from taking effect due to damage or failure, causing the washing machine to shut down, taking effect when the switch key is triggered for the second time and meets the effective condition, ensuring that the washing machine can normally start and shut down when other keys are damaged or fail, and improving the control effect of key taking effect.
