step S102, a first difference value between a first key value generated by the touch key and a reference value and a system threshold value are obtained, wherein the reference value is the key value generated when the touch key is not triggered.
Specifically, the system threshold may be a threshold preset when the cooking appliance leaves a factory, the threshold is stored in a memory of the cooking appliance, the cooking appliance may automatically read the system threshold stored in the memory after being powered on, and whether the touch key is valid is determined through the system threshold, where the cooking appliance may be an electric pressure cooker, an electric rice cooker, a food processor, and the like.

And step S106, under the condition that the touch key is judged to be invalid, acquiring a plurality of difference value intervals and a threshold value adjusting mode corresponding to each difference value interval.
Optionally, the number of the plurality of difference intervals is 2-6.
Specifically, 2-6 difference intervals can be preset according to the actual use environment, and the threshold value adjustment modes corresponding to each difference interval are different, so that the adjusted threshold values are different, that is, the sensitivities of different use environments are different.
Step S108, matching the first difference value with the plurality of difference value intervals to obtain a threshold adjustment manner corresponding to the first difference value.
And step S110, adjusting the system threshold according to the threshold adjusting mode corresponding to the first difference value to obtain an adjusted threshold.
In an optional scheme, after the cooking appliance is powered on, the key value generated by the touch key can be detected in real time, whether the touch key is valid or not is judged by calculating the difference value between the key value and the reference value and combining with the system threshold value read from the memory, and in order to further judge whether the touch key is invalid due to the change of the use environment, a corresponding threshold value adjusting mode can be selected according to the calculated difference value after the touch key is judged to be invalid, so that the sensitivity meeting the current use environment is obtained.
According to the above embodiment of the present invention, the key value generated by the touch key can be obtained in real time, the variation of the key value can be obtained according to the difference between the key value and the reference value, by comparing the variation of the key value with the system threshold value, whether the touch key is effective is determined, a plurality of difference value intervals can be further divided in advance, the threshold value adjusting modes corresponding to the difference value intervals are different, under the condition that the touch key is judged to be invalid, the corresponding threshold value adjusting mode can be obtained according to the change quantity of the key value, and the system threshold value is adjusted, so that the touch key can be used for different use environments, the sensitivity of the touch key is adjusted in different modes, thereby achieving the technical effects of improving the accuracy of judging the touch key and expanding the application range of the touch key, and then the technical problem that the touch key is possibly invalid due to the fact that the sensitivity of the touch key in the prior art is fixed is solved.
Optionally, the plurality of difference intervals comprises: a first difference interval, a second difference interval, and a third difference interval, where, in step S110, the system threshold is adjusted according to a threshold adjustment mode corresponding to the first difference, and obtaining an adjusted threshold includes: under the condition that the first difference value and the first difference value interval are successfully matched, taking a first preset threshold value as an adjusted threshold value; under the condition that the first difference value and the second difference value are matched successfully, taking a second preset threshold value as an adjusted threshold value; and under the condition that the first difference value and the third difference value are matched successfully, taking the system threshold value as the adjusted threshold value.
Optionally, the first difference interval is smaller than the system threshold and greater than or equal to the product of the system threshold and the first preset value, the second difference interval is smaller than the product of the system threshold and the first preset value and greater than or equal to the product of the system threshold and the second preset value, and the third difference interval is smaller than the product of the system threshold and the second preset value, wherein the first preset value and the second preset value are smaller than 1, and the first preset value is greater than the second preset value.
Optionally, the first preset value is 0.6, and the second preset value is 0.2.
In an optional scheme, under the condition of the read system threshold value X1, three difference intervals may be preset, where a first difference interval is 0.6 × X1 to X1, a second difference interval is 0.2 × X1 to 0.6 × X1, and a third difference interval is 0 to 0.2 × X1, and if the calculated difference is in the first difference interval, that is, the difference is successfully matched with the first difference interval, the first preset threshold value X2 may be used as a new system threshold value; if the calculated difference value is in the second difference value interval, that is, the difference value is successfully matched with the second difference value interval, the second preset threshold value X3 may be used as a new system threshold value; if the calculated difference value is in the third difference value interval, that is, the difference value is successfully matched with the third difference value interval, the current system threshold value may not be changed, that is, the current system threshold value is used as a new system threshold value.
It should be noted that, when the first difference and the third difference are successfully matched, it may be determined that the key value is substantially the same as the reference value at this time, and it is determined that the usage environment is not changed, and the key value is different from the reference value due to normal fluctuation or system abnormal fluctuation. For example, when the first difference is less than or equal to 0.1 × X1, the per-key value is determined to be a normal fluctuation; when 0.1 × X1 < the first difference <0.2 × X1, the key value is determined to be a system abnormal fluctuation.
According to the scheme, three difference value intervals are divided in advance, the threshold value adjusting mode corresponding to the first difference value interval and the second difference value interval is that the system threshold value is replaced by the corresponding preset threshold value, the adjusting mode corresponding to the third difference value interval is not adjusted, the first preset value is set to be 0.6, the second preset value is set to be 0.2, the first difference value interval, the second difference value interval and the third difference value interval are sequentially reduced, the situation that the system threshold value is changed due to fluctuation of key values and the accuracy of touch key judgment is affected is avoided, the accuracy of touch key judgment is further improved, and the application range of the touch key is expanded.

In an alternative scheme, after determining that 0.2 × X1 is not greater than the first difference value <0.6 × X1, the key value of the touch key may be obtained again after the touch key is released, and if the result of the resampling is consistent with the previous sampling, that is, the second difference value obtained from the result of the resampling satisfies 0.2 × X1 is not greater than the second difference value <0.6 × X1, the second preset threshold may be determined as a new system threshold; if the result of the resampling does not coincide with the previous sampling, a new system threshold may be determined based on the result of the resampling, e.g., if the second difference < 0.2X 1, the system threshold is not processed; if 0.6X 1 is less than or equal to the second difference, the second predetermined threshold may be determined as the new system threshold.
Through the scheme, after the first difference value is determined to belong to the second difference value interval, the touch key is released and sampling is performed again, the system threshold value is replaced by the second preset threshold value if sampling for two times is consistent, and adjustment is performed according to the key value of the sampling for the second time if sampling for two times is inconsistent, so that the effects of improving the accuracy of judgment of the touch key and expanding the application range of the touch key are achieved.
Optionally, in step S110, the system threshold is adjusted according to the threshold adjustment mode corresponding to the first difference value, after the adjusted threshold is obtained, the adjusted threshold is stored in the memory, and after the power is turned on again, the adjusted threshold is used as the system threshold.
In an optional scheme, after the system threshold is adjusted, a new system threshold may be stored in the memory, specifically, it may be determined whether the new system threshold is the same as the system threshold before the adjustment, and if the new system threshold is the same as the system threshold before the adjustment, the new system threshold may not be stored because the system threshold is unchanged; if the system threshold value is different from the system threshold value, the new system threshold value can be stored in the memory, so that after the cooking appliance is powered on again, the new system threshold value stored in the memory can be directly read, and whether the touch key is effective or not can be judged according to the new system threshold value.
Through the scheme, after the system threshold is adjusted, the adjusted threshold is stored in the memory, so that after the cooking appliance is powered on again, the adjusted threshold can be used as the system threshold, the accuracy of touch key judgment is further improved, and the application range of the touch key is expanded.

By the scheme, the key value of the cooking appliance during power-on is used as the reference value, so that whether the touch key is effective or not is determined, the accuracy of judging the touch key is further improved, and the application range of the touch key is expanded.
