Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular, to a control method for a household electrical appliance, a household electrical appliance, and a computer-readable storage medium. Background Art

[0002] In the related art, the control panel of a household electrical appliance mostly adopts touch buttons. When there is water on the user's hand or water droplets on the touch button, multiple touch buttons may be triggered simultaneously, resulting in touch failure and poor user experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a control method for a household electrical appliance.

[0005] A second aspect of the present invention provides a household electrical appliance.

[0006] A third aspect of the present invention provides a computer-readable storage medium.

[0007] In view of this, a first aspect of the present invention provides a control method for a household electrical appliance. The household electrical appliance includes a plurality of function keys, and the function keys can respond to a trigger operation and generate corresponding trigger signals. The control method includes: in response to the trigger signal, obtaining a trigger induction amount corresponding to the trigger signal; determining a target function key from the plurality of function keys according to the trigger induction amount, and controlling the household electrical appliance to execute the function corresponding to the target function key.

[0008] In this technical solution, the target function key is determined from the plurality of function keys by obtaining the trigger induction amount of the trigger signal. Specifically, for a touch button, such as a capacitive touch button, when a user's finger touches the button, a coupling capacitance will be formed. Therefore, a threshold, such as a coupling capacitance threshold, is generally set. When the sensed coupling capacitance value exceeds the coupling capacitance threshold, a trigger signal will be generated correspondingly. When there is water on the user's hand, the coupling capacitance formed by the water droplets may also exceed the capacitance threshold, resulting in the simultaneous generation of multiple trigger signals.

[0009] In an embodiment of the present invention, by further determining the trigger induction amount corresponding to the trigger signal, and according to the magnitude of the trigger induction amount, among the function keys corresponding to the multiple possible trigger signals, a target function key is determined. The target function key is the function key that the user is most likely to touch, and then the household electrical appliance is controlled to execute the function corresponding to the target function key to meet the actual needs of the user.

[0010] Applying the embodiment provided by the present invention, after receiving the trigger signal of the function key, a target function key is further determined through the trigger induction amount of the trigger signal, thereby avoiding the mis-touch phenomenon caused by the external environment, enabling the home appliance device to always execute the function desired by the user, avoiding the situation of touch failure, and effectively improving the use experience of the home appliance device.

[0011] In addition, the control method of the home appliance device in the above technical solution provided by the present invention may further have the following additional technical features:

[0012] In the above technical solution, the step of determining the target function key from multiple function keys according to the trigger induction amount specifically includes: based on the situation that the trigger induction amount is within the target intensity range, determining the corresponding trigger signal as a valid trigger signal; based on the situation that the number of valid trigger signals is multiple, determining the function key corresponding to the valid trigger signal with the largest trigger induction amount as the target function key.

[0013] In this technical solution, different from the traditional method of judging whether it is a valid trigger by setting a lower threshold, the embodiment of the present invention sets a target intensity range, that is, defines a lower limit value and at the same time defines an upper limit value. Only when the trigger induction amount corresponding to the trigger signal is within this target intensity range, the corresponding trigger signal is determined to be a valid trigger signal. Thereby, it can effectively avoid the mis-trigger caused by signal abnormality, improve the accuracy of the touch button, and further improve the control experience of the home appliance device.

[0014] If there are multiple valid trigger signals at the same time, that is, when the trigger induction amounts respectively corresponding to multiple trigger signals all fall within the target intensity range, then according to the size of the trigger induction amount, the multiple valid trigger signals are sorted, and the valid trigger signal with the largest trigger induction amount in the sorted sequence is selected as the signal for final control, and the function key corresponding to the valid trigger signal with the largest trigger induction amount is determined as the target function key to control the home appliance device to execute the function corresponding to the target function key.

[0015] Specifically, taking the function key as a capacitive touch key as an example, since the target intensity range is determined according to the effective touch value of the user, when the user accurately touches a function key, a trigger signal with a large trigger induction amount is generally triggered, such as forming a large coupling capacitance value. If there are water droplets on the panel, or when the user's finger touches and presses a function key, and other parts of the side of the finger touch other function keys, causing other function keys to be triggered, since the function key accurately touched by the user's finger has the largest contact area with the user's body, a large coupling capacitance will be formed, that is, a larger trigger induction amount. Therefore, selecting the target function key according to the effective trigger signal with the largest trigger induction amount can more accurately determine the function that the user actually wants to execute.

[0016] In the embodiment of the present invention, by comparing the trigger induction amounts of multiple effective trigger signals and selecting the effective trigger signal with the largest trigger induction amount to determine the final target function key, it can effectively avoid the situation that multiple function keys are simultaneously triggered due to water droplets, environmental humidity or the user's "off-target pressing", resulting in mis-triggering or key failure, so that the household electrical appliance can always execute the function desired by the user, thereby effectively improving the use experience of the household electrical appliance.

[0017] In any of the above technical solutions, based on the fact that there are multiple effective trigger signals and there is a situation where the trigger induction amounts corresponding to at least two effective trigger signals are equal and the largest, the step of determining the target function key from multiple function keys according to the trigger induction amount further includes: obtaining the priority of each function key corresponding to each effective trigger signal among at least two effective trigger signals; determining the function key with the highest priority as the target function key.

[0018] In this technical solution, since the contact area between the function key accurately touched by the user's finger and the user's body is larger than that of the function key touched by other parts of the user's hand or mis-triggered due to environmental factors such as water droplets, the trigger induction amount of the effective trigger signal corresponding to the function key actually touched by the user is generally larger than that of the mis-triggered effective trigger signal.

[0019] For some special situations, there will still be a situation where among the multiple generated effective trigger signals, there are two or more effective trigger signals whose corresponding trigger induction amounts are exactly equal, or the trigger induction amounts of these effective trigger signals are very close, and the recognition accuracy of the system cannot distinguish the size of their trigger induction amounts. For the above situations, in order to accurately identify the function to be realized by the user, the embodiment of the present invention sets a unique priority for each function key. When the trigger induction amounts of more than two effective trigger signals are recognized as the same, obtain the priorities of the function keys corresponding to these effective trigger signals, perform secondary sorting on these function keys according to the priority order, and select the function key with the highest priority as the target function key.

[0020] For example, assume that the function keys of a household electrical appliance device include a power key, a start / pause key, and a preset function key. The priorities are set for the above three function keys as follows: The power key has the highest priority, which is set to 3; the start / pause key has a priority of 2; the preset function key has the lowest priority, which is set to 1. If all of the above three function keys are triggered to be valid trigger signals and the trigger induction amounts are equal, only the function corresponding to the power key with the highest priority is executed.

[0021] In an embodiment of the present invention, by setting a unique priority for each function key, when a special situation where the trigger induction amounts are equal occurs, the touch operation can still be accurately executed, avoiding touch failure and improving the user experience.

[0022] In any of the above technical solutions, the control method further includes: in response to a setting instruction, obtaining a plurality of sample trigger signals; calculating an average value of the trigger induction amounts corresponding to the sample trigger signals, and determining a target intensity range according to the average value.

[0023] In this technical solution, in order to ensure the accuracy of the target intensity range, in an embodiment of the present invention, the setting mode is entered through a setting instruction. Specifically, this setting operation can be performed before the household electrical appliance device leaves the factory. After receiving the setting instruction, the household electrical appliance device enters the setting mode. At this time, the function keys start to continuously obtain sample trigger signals. During the corresponding operation, testers with different physical conditions (different ages, genders, weights, and skin states) can touch each function key multiple times respectively to obtain a sufficient number of sample trigger signals.

[0024] After collecting sufficient sample trigger signals, the trigger induction amount corresponding to each sample trigger signal is obtained and determined respectively, and the average value of these trigger induction amounts is calculated. This average value can reflect the trigger induction amounts of different possible users when touching the function keys. Therefore, by determining the target intensity range through the obtained average value, it can accurately cover the possible trigger induction amounts of users with different application conditions, and at the same time eliminate the "false trigger" signals caused by environmental factors, improve the recognition accuracy of the function keys, and further improve the user experience of the household electrical appliance device.

[0025] In any of the above technical solutions, the step of determining the target intensity range according to the average value specifically includes: calculating the product of the average value and a preset constant; taking the difference between the average value and the product as the lower limit, and taking the sum of the average value and the product as the upper limit to determine the target intensity range; where the range of the preset constant is: 1 / 12 to 1 / 4.

[0026] In this technical solution, first, the average value of multiple trigger induction amounts of the sample trigger signal is calculated. Here, let this average value be X. Then, the product of the average value X and the preset constant is calculated. Here, let this product be ΔX. Specifically, according to the specific model performance of the touch chip, the preset constant can be set to 1 / 12 to 1 / 4. That is to say, ΔX will be much smaller than X, and the specific value range can be set to 1 / 12X to 1 / 4X.

[0027] Taking the sum of the average value X and the product ΔX, that is, X + ΔX as the upper limit, and at the same time taking the difference between the average value X and the product, that is, X - ΔX as the lower limit, the target intensity range, (X - ΔX, X + ΔX), can be determined. This target intensity range is the intensity range that can accurately identify the touch operations of different users. When the trigger induction amount corresponding to a touch signal falls within the interval of (X - ΔX, X + ΔX), the touch signal is identified as a valid touch signal, which can accurately cover the possible trigger induction amounts of users with different application statuses, and at the same time eliminate the "false trigger" signals caused by environmental factors, improve the recognition accuracy of the function keys, and thus improve the use experience of the home appliance device.

[0028] In any of the above technical solutions, the trigger induction amount is: current value, voltage value, capacitance value or resistance value.

[0029] In this technical solution, the function key can be selected and set as a membrane switch, a capacitive touch switch, a clear switch or a micro switch, etc. according to the specific model, appearance design, function requirements or market reaction of the home appliance device. Therefore, according to the specific hardware of the function key, for the function key with a current signal, the trigger induction amount can specifically correspond to the current value; for the function key with a voltage signal, the trigger induction amount can also specifically correspond to the voltage value; for the capacitive function key, the trigger induction amount can also specifically correspond to the capacitance value; for the resistive function key, the trigger induction amount can also specifically correspond to the resistance value.

[0030] In any of the above technical solutions, the step of determining the target function key from multiple function keys according to the trigger induction amount further includes: based on the situation where the number of valid trigger signals is one, determining the function key corresponding to the valid trigger signal as the target function key.

[0031] In this technical solution, when only the trigger induction amount corresponding to one trigger signal falls within the target intensity range, it means that there is no "interference signal" or "false touch signal" at present. Therefore, this unique trigger signal can be used as a valid trigger signal, and the function key corresponding to this valid trigger signal can be determined as the target function key to control the home appliance device to execute the corresponding function.

[0032] In any of the above technical solutions, the household electrical appliance includes at least one of the following: washing machine, water heater, water dispenser, refrigerator, air conditioner, electric fan, range hood, electric oven, microwave oven, rice cooker, automatic cooking machine.

[0033] In this technical solution, the household electrical appliance can be any household electrical appliance with touch function keys, such as a washing machine, water heater, water dispenser, refrigerator, air conditioner, electric fan, range hood, electric oven, microwave oven, rice cooker or automatic cooking machine. It can be understood that the types of household electrical appliances in the embodiments of the present invention include but are not limited to the household electrical appliance types mentioned above. Any household electrical appliance applying touch function keys is a feasible embodiment of the present invention.

[0034] The second aspect of the present invention provides a household electrical appliance, which includes a memory and a processor. The memory is used to store a computer program, and the processor is used to implement the control method of the household electrical appliance provided in any of the above technical solutions when executing the computer program on the memory. Therefore, this household electrical appliance also includes all the beneficial effects of the control method of the household electrical appliance provided in any of the above technical solutions, which will not be elaborated here.

[0036] In this technical solution, the household electrical appliance includes a plurality of function keys, and each function key corresponds to a function of the household electrical appliance. When the user touches a function key, the function key can generate a corresponding trigger signal according to the user's touch operation. The trigger signal has a certain trigger induction amount, and the household electrical appliance judges whether the trigger signal is a valid trigger signal according to the trigger induction amount, and then controls the household electrical appliance to execute the corresponding function, which can avoid false touch caused by the external environment, so that the household electrical appliance can always execute the function desired by the user, avoid the situation of touch failure, and effectively improve the use experience of the household electrical appliance.

[0047] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0048] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0049] Next, refer to Figures 1 to 8 Describe the control method of the household electrical appliance, the household electrical appliance and the computer-readable storage medium according to some embodiments of the present invention.

[0050] Embodiment 1

[0051] Figure 1FIG. 0 shows one of the flowcharts of the control method of a household electrical appliance according to an embodiment of the present invention. A plurality of function keys are provided on the household electrical appliance, and each function key can respond to a user's triggering operation and generate a corresponding triggering signal according to the triggering operation. Specifically, the control method of the household electrical appliance may include the following steps:

[0052] Step 102, after receiving the triggering signal, obtain the triggering induction amount of the triggering signal;

[0053] Step 104, determine a target function key among a plurality of function keys according to the obtained triggering induction amount;

[0054] Step 106, control the household electrical appliance to execute the function corresponding to the target function key.

[0055] In steps 102 and 104, the triggering induction amount is: a current value, a voltage value, a capacitance value or a resistance value.

[0056] In the embodiment of the present invention, by obtaining the triggering induction amount of the triggering signal, a target function key is determined among a plurality of function keys. Specifically, for a touch key, such as a capacitive touch key, when a user's finger touches the key, a coupling capacitance will be formed. Therefore, a threshold value, such as a coupling capacitance threshold value, is generally set. When the sensed coupling capacitance value exceeds the coupling capacitance threshold value, a triggering signal will be generated correspondingly. When the user's hand is wet, it may cause the coupling capacitance formed by the water droplets to also exceed the capacitance threshold value, so that multiple triggering signals will be generated simultaneously.

[0057] Among them, the function key can be selected to set a membrane switch, a capacitive touch switch, a clear switch or a micro switch, etc. according to the specific model, appearance design, function requirements or market response of the household electrical appliance. Therefore, according to the specific hardware of the function key, for a function key with a current signal, the triggering induction amount can specifically correspond to a current value, for a function key with a voltage signal, the triggering induction amount can also specifically correspond to a voltage value, for a capacitive function key, the triggering induction amount can also specifically correspond to a capacitance value, and for a resistive function key, the triggering induction amount can also specifically correspond to a resistance value.

[0058] The embodiment of the present invention further determines the triggering induction amount corresponding to the triggering signal, and determines a target function key among the function keys corresponding to multiple possible triggering signals according to the magnitude of the triggering induction amount. The target function key is the function key that the user is most likely to touch, and then controls the household electrical appliance to execute the function corresponding to the target function key to meet the actual needs of the user.

[0059] Applying the embodiment provided by the present invention, after receiving the trigger signal of the function key, a target function key is further determined through the trigger induction amount of the trigger signal, thereby avoiding the phenomenon of accidental touch caused by the external environment, enabling the household appliance device to always execute the function desired by the user, avoiding the situation of touch failure, and effectively improving the use experience of the household appliance device.

[0060] Embodiment Two

[0061] Figure 2 Fig. 2 shows the second flowchart of the control method of the household appliance device provided by the embodiment of the present invention. Specifically, the control method of the household appliance device may include the following steps:

[0062] Step 202, after receiving the trigger signal, obtain the trigger induction amount of the trigger signal;

[0063] Step 204, when the trigger induction amount falls within the target intensity range, determine the corresponding trigger signal as a valid trigger signal;

[0064] Step 206, if there are multiple valid trigger signals, determine the valid trigger signal with the largest trigger induction amount, and determine the function key corresponding to it as the target function key;

[0065] Step 208, control the household appliance device to execute the function corresponding to the target function key.

[0066] In the embodiment of the present invention, the target function key is determined among multiple function keys by obtaining the trigger induction amount of the trigger signal. Different from the traditional method of judging whether it is a valid trigger by setting a lower threshold, the embodiment of the present invention sets a target intensity range, that is, defines a lower limit value and simultaneously defines an upper limit value. Only when the trigger induction amount corresponding to the trigger signal is within the target intensity range, it is determined that the corresponding trigger signal is a valid trigger signal, thereby effectively avoiding accidental triggers caused by signal abnormalities, improving the accuracy of touch buttons, and further improving the control experience of household appliance devices.

[0067] If there are multiple valid trigger signals at the same time, that is, the trigger induction amounts respectively corresponding to multiple trigger signals all fall within the target intensity range, then according to the magnitude of the trigger induction amount, the multiple valid trigger signals are sorted, and the valid trigger signal with the largest trigger induction amount in the sorted sequence is selected as the signal for final control, and the function key corresponding to the valid trigger signal with the largest trigger induction amount is determined as the target function key to control the household appliance device to execute the function corresponding to the target function key.

[0068] Specifically, taking the function key as a capacitive touch button as an example, since the target intensity range is determined according to the user's effective touch value, when the user accurately touches a function key, generally a trigger signal with a large trigger induction amount will be triggered, such as forming a large coupling capacitance value. And if there are water droplets on the panel, or when the user's finger touches and presses a function key, and other parts of the side of the finger touch other function keys, resulting in the triggering of other function keys, since the function key accurately touched by the user's finger has the largest contact area with the user's body, a large coupling capacitance will be formed, that is, a larger trigger induction amount. Therefore, by selecting an effective trigger signal with the largest trigger induction amount to determine the target function button, the function that the user actually wants to execute can be determined more accurately.

[0069] In the embodiment of the present invention, by comparing the trigger induction amounts of multiple effective trigger signals and selecting an effective trigger signal with the largest trigger induction amount to determine the final target function button, it can effectively avoid the situation of simultaneously triggering multiple function keys due to water droplets, environmental humidity, or the user "pressing off", resulting in mis-triggering or button failure, so that the household electrical appliance device can always execute the function desired by the user, thereby effectively improving the use experience of the household electrical appliance device.

[0070] Embodiment 3

[0071] Figure 3 Fig. 3 shows the third flowchart of the control method of the household electrical appliance device provided by the embodiment of the present invention. Specifically, the control method of the household electrical appliance device may include the following steps:

[0072] Step 302, after receiving the trigger signal, obtain the trigger induction amount of the trigger signal;

[0073] Step 304, when the trigger induction amount falls within the target intensity range, determine the corresponding trigger signal as an effective trigger signal;

[0074] Step 306, if there are multiple effective trigger signals, and the trigger induction amounts corresponding to at least two of the effective trigger signals are equal and the largest, obtain the priorities of the function keys corresponding to each of the at least two effective trigger signals;

[0075] Step 308, determine the function key with the highest priority as the target function key.

[0076] Step 310, control the household electrical appliance device to execute the function corresponding to the target function key.

[0077] In an embodiment of the present invention, by obtaining the triggering induction amount of a triggering signal, a target function key is determined among a plurality of function keys. Different from the traditional method of determining whether it is a valid trigger by setting a lower threshold, in the embodiment of the present invention, a target intensity range is set, that is, a lower limit value is defined, and at the same time an upper limit value is defined. Only when the triggering induction amount corresponding to the triggering signal is within the target intensity range, the corresponding triggering signal is recognized as a valid triggering signal. Thus, it is possible to effectively avoid false triggers caused by signal abnormalities, improve the accuracy of touch keys, and further improve the control experience of household electrical appliances.

[0078] If there are multiple valid triggering signals at the same time, that is, when the triggering induction amounts respectively corresponding to multiple triggering signals all fall within the target intensity range, since the contact area between the function key accurately touched by the user's finger and the user's body is larger than that of the function key touched by other parts of the user's hand or mis-triggered due to environmental factors such as water droplets, the triggering induction amount of the valid triggering signal corresponding to the function key actually touched by the user is generally greater than that of the mis-triggered valid triggering signal.

[0079] For some special cases, after sorting multiple valid triggering signals according to the magnitude of the triggering induction amount, there will be two or more valid triggering signals whose corresponding triggering induction amounts are exactly equal and the largest, or the triggering induction amounts of these valid triggering signals are very close, and the recognition accuracy of the system cannot distinguish the magnitudes of their triggering induction amounts. For the above situations, in order to accurately identify the function to be realized by the user, in the embodiment of the present invention, each function key is set with a unique priority. When the triggering induction amounts of two or more valid triggering signals are recognized as the same and the largest, the priorities of the function keys corresponding to these valid triggering signals are obtained, and these function keys are sorted secondarily according to the priority order, and the function key with the highest priority is selected as the target function key.

[0080] For example, assume that the function keys of a household electrical appliance include a power key, a start / pause key, and a preset function key. The priorities are set for the above three function keys as follows: the power key has the highest priority, set to 3; the start / pause key has a priority set to 2; the preset function key has the lowest priority, set to 1. If all of the above three function keys are triggered as valid triggering signals and the triggering induction amounts are equal and the largest, only the function corresponding to the power key with the highest priority is executed.

[0081] In the embodiment of the present invention, by setting a unique priority for each function key, when a special situation where the triggering induction amounts are equal occurs, the touch operation can still be accurately executed, touch failure is avoided, and the user experience is improved.

[0082] Embodiment 4

[0083] Figure 4 Figure 4 shows a flowchart of a control method for a home appliance according to an embodiment of the present invention. Specifically, the control method for the home appliance may include the following steps:

[0084] Step 402: Continuously obtain a plurality of sample trigger signals after receiving a setting instruction;

[0085] Step 404: Calculate the average value of the trigger induction amounts corresponding to the plurality of sample trigger signals, and determine a target intensity range based on this average value.

[0086] In the embodiment of the present invention, in order to ensure the accuracy of the target intensity range, the embodiment of the present invention enters the setting mode through a setting instruction. Specifically, this setting operation can be performed before the home appliance leaves the factory. After receiving the setting instruction, the home appliance enters the setting mode. At this time, the function keys start to continuously obtain sample trigger signals. During the corresponding operation, testers with different physical conditions (different ages, genders, weights, and skin conditions) can touch each function key multiple times respectively to obtain a sufficient number of sample trigger signals.

[0087] After collecting sufficient sample trigger signals, the trigger induction amount corresponding to each sample trigger signal is obtained and determined respectively, and the average value of these trigger induction amounts is calculated. This average value can reflect the trigger induction amounts of different possible users when touching the function keys. Therefore, determining the target intensity range based on the obtained average value can accurately cover the possible trigger induction amounts of users with different application conditions, and at the same time eliminate the "false trigger" signals caused by environmental factors, improve the recognition accuracy of the function keys, and thus improve the use experience of the home appliance.

[0088] Figure 5 Figure 5 shows a flowchart of a control method for a home appliance according to an embodiment of the present invention. Specifically, the control method for the home appliance may include the following steps:

[0089] Step 502: Continuously obtain a plurality of sample trigger signals after receiving a setting instruction;

[0090] Step 504: Calculate the average value of the trigger induction amounts corresponding to the plurality of sample trigger signals, and calculate the product of the average value and a preset constant;

[0091] Step 506: Determine the target intensity range with the difference between the average value and the product as the lower limit and the sum of the average value and the product as the upper limit.

[0092] In step 504, the range of the preset constant is: 1 / 12 to 1 / 4.

[0093] In an embodiment of the present invention, first, the average value of multiple trigger induction amounts of a sample trigger signal is calculated. Here, let this average value be X. Then, the product of the average value X and a preset constant is calculated. Here, let this product be ΔX. Specifically, according to the specific model performance of the touch chip, the preset constant can be set to 1 / 12 to 1 / 4. That is to say, ΔX will be much smaller than X, and the specific value range can be set to 1 / 12X to 1 / 4X.

[0094] Taking the sum of the average value X and the product ΔX, that is, X + ΔX as the upper limit, and at the same time taking the difference between the average value X and the product, that is, X - ΔX as the lower limit, a target intensity range, (X - ΔX, X + ΔX), can be determined. This target intensity range is the intensity range that can accurately identify the touch operations of different users. When the trigger induction amount corresponding to a touch signal falls within the interval of (X - ΔX, X + ΔX), the touch signal is identified as a valid touch signal, which can accurately encompass the possible trigger induction amounts of users with different application statuses, and at the same time eliminate the "false trigger" signals caused by environmental factors, improve the recognition accuracy of the function keys, and thus improve the use experience of the household electrical appliance device.

[0095] Embodiment Five

[0096] Figure 6 Fig. 6 shows a flowchart of a control method for a household electrical appliance device according to an embodiment of the present invention. Specifically, the control method of the household electrical appliance device may include the following steps:

[0097] Step 602, after receiving a trigger signal, obtain the trigger induction amount of the trigger signal;

[0098] Step 604, when the trigger induction amount falls within the target intensity range, determine the corresponding trigger signal as a valid trigger signal;

[0099] Step 606, when the number of valid trigger signals is one, determine the function key corresponding to the valid trigger signal as the target function key.

[0100] In an embodiment of the present invention, by obtaining the trigger induction amount of the trigger signal, the target function key is determined among multiple function keys. Different from the traditional method of judging whether it is a valid trigger by setting a threshold lower limit, in an embodiment of the present invention, by setting a target intensity range, that is, defining a lower limit value and at the same time defining an upper limit value, when and only when the trigger induction amount corresponding to the trigger signal is within this target intensity range, the corresponding trigger signal is determined to be a valid trigger signal, and thus the false trigger caused by signal abnormality can be effectively avoided, the accuracy of the touch key can be improved, and thus the control experience of the household electrical appliance device can be improved.

[0101] If only the trigger induction quantity corresponding to one trigger signal falls within the target intensity range, it indicates that there is no "interference signal" or "false trigger signal" currently. Therefore, this unique trigger signal can be used as the valid trigger signal, and the function key corresponding to this valid trigger signal can be determined as the target function key to control the household electrical appliance to execute the corresponding function.

[0102] In some embodiments of the present invention, the household electrical appliance includes at least one of the following: washing machine, water heater, water dispenser, refrigerator, air conditioner, electric fan, range hood, electric oven, microwave oven, rice cooker, automatic cooking machine.

[0103] Specifically, the household electrical appliance can be any household electrical appliance with touch function keys, such as a washing machine, water heater, water dispenser, refrigerator, air conditioner, electric fan, range hood, electric oven, microwave oven, rice cooker or automatic cooking machine. It can be understood that the types of household electrical appliances in the embodiments of the present invention include but are not limited to the above-mentioned household electrical appliance types, and any household electrical appliance applying touch function keys is a feasible embodiment of the present invention.

[0104] Embodiment Six

[0105] In the embodiment of the present invention, taking the household electrical appliance as a washing machine, where there are at least three function keys set on the washing machine, one of the function keys is the power key, the second function key is the start / pause key, and the third function key is other function keys as an example, the embodiments of the present invention will be specifically described.

[0106] Figure 7 The control logic block diagram of the function keys of the washing machine according to the embodiment of the present invention is shown. Among them, the washing machine control system 702 is the main control component of the washing machine. The washing machine control system 702 can generate drive signals for each component of the washing machine according to the operation instructions, and then realize each phase function of the washing machine.

[0107] Among the function keys, the power key 706, the start / pause key 708 and the other function key 710 are all connected to the touch control chip 704. When the user touches the above function keys, a trigger signal with a certain trigger induction quantity will be formed. The touch control chip 704 determines which function key is specifically triggered according to the trigger signal, and then sends this signal to the washing machine control system 702, and finally controls the washing machine to execute the corresponding function.

[0108] During the touch control process, in a normal environment, assuming that the touch induction quantity of the human body is between 2α and 3α, and the trigger threshold is set to α, then during the normal use process by the user, each touch control button can be normally triggered.

[0109] However, due to environmental impacts, such as in some areas being relatively humid and hot (or the washing machine being placed in a humid environment such as a bathroom), the user's fingers are wet, or the buttons are wet. During the touch process, it may occur that multiple buttons are triggered simultaneously (the triggering induction amounts of multiple triggers all exceed the triggering threshold). In this case, the touch control chip cannot determine which button the user is pressing, or whether the user is using the combined button function, resulting in the washing machine being unable to work properly.

[0110] To solve the above problems, embodiments of the present invention first define the activation method of the combined buttons. Since combined buttons are generally used for pre - factory testing and users do not use combined buttons during daily use, the activation conditions of the combined buttons can be set to relatively strict conditions. For example, only within 10 seconds after the washing machine is powered on, the combined buttons can be recognized, and after more than 10 seconds, the combined buttons cannot be activated.

[0111] Meanwhile, embodiments of the present invention limit the target intensity range of the effective trigger signal. Specifically, assume that the normal triggering induction amount of the user is X, where X can be determined by repeatedly triggering the function keys by multiple testers to input sample trigger signals and calculating the average value of the triggering induction amounts of the sample trigger signals. This application limits the target intensity range between X - ΔX and X + ΔX, where ΔX is much smaller than X. Depending on the touch control chip, the value of ΔX can be set to 1 / 10 to 1 / 5 of X.

[0112] Among them, X - ΔX is also greater than the triggering threshold α.

[0113] When mis - triggering occurs, that is, when there are multiple effective trigger signals simultaneously, assume that the triggering induction amount of the power button is M, and the triggering induction amount of the start / pause button is N, and satisfy X - ΔX < M < X + ΔX, and at the same time satisfy X - ΔX < N < X + ΔX, then continue to compare the magnitudes of M and N.

[0114] If M > N, it is determined that the user touches the power button, and at this time, the washing machine is controlled to only execute the function corresponding to the power button, such as turning on or off.

[0115] If M < N, it is determined that the user touches the start / pause button, and at this time, the washing machine is controlled to only execute the function corresponding to the start / pause button, such as starting washing or pausing washing.

[0116] If a special situation of M = N occurs, then further obtain the priorities of the power button and the start / pause button. Generally speaking, the priority of the power button is higher than that of the start / pause button. At this time, the washing machine is controlled to only execute the function corresponding to the power button.

[0117] By comparing the trigger induction amounts of multiple valid trigger signals and selecting the valid trigger signal with the largest trigger induction amount to determine the final target function key, and setting a unique priority for each function key, in the special case where the trigger induction amounts are equal, it can effectively avoid the situation of multiple function keys being triggered simultaneously due to water droplets, environmental humidity, or the user pressing "off-center", resulting in mis-triggering or key failure, so that the household electrical appliance can always execute the function desired by the user, thereby effectively improving the use experience of the household electrical appliance.
