In some embodiments, the household appliance 100 may be a refrigerator. The touch device 120 may be disposed on a door located on the upper side of the refrigerator.
In the illustrated embodiment, the refrigerator may include a cabinet 110 defining a refrigerating compartment and a freezing compartment, and a refrigerating door 111 and a freezing door 112 for opening and closing the refrigerating compartment and the freezing compartment, respectively, and the touch device 120 is disposed on the refrigerating door 111 located at an upper side.
In other embodiments, the household appliance 100 may also be an air conditioner, a washing machine, a water heater, or other household appliances 100.
The memory may store a computer program. The computer program is executable by a processor for implementing a control method for the home appliance 100 of the embodiment of the present invention.
Fig. 2 is a schematic front view of the touch area 130 in fig. 1. Referring to fig. 2, each touch area 130 may be divided into an active area 131 and an inactive area 132. In the illustrated embodiment, the predetermined active area 131 may be a middle portion of the touch area 130, and the inactive area 132 may be annular and located outside the active area 131.
In particular, the processor may be configured to acquire an action position of a touch operation applied to the touch device 120, and determine that the touch operation is valid when the action position is located in the valid area 131 of the touch area 130 of the touch device 120; when the action position is located outside the effective area 131 of the touch area 130 of the touch device 120, it is determined that the touch operation is invalid, and the touch operation is a false touch.
The household appliance 100 of the invention judges whether the touch operation is effective or not through the action position of the touch operation, and compared with the method for judging whether the touch operation is effective or not through detecting the action direction of the touch operation, the influence of factors such as the height of a user, the standing position of the user and the like can be avoided, and the accuracy is higher.
In some embodiments, in the case that the touch operation is determined to be valid, the processor may be further configured to obtain operation information of the touch operation, and output a corresponding control signal according to the operation information, so as to obtain a plurality of control instructions through one key, thereby reducing the occupied area of the touch area 130.

While obtaining the operation information of the touch operation, the processor may be further configured to output a feedback signal to cause the touch device 120 to generate corresponding frequency and amplitude vibrations according to the pressing pressure and the pressing time, so that the user can more accurately implement the corresponding touch action of the instruction that the user desires to input, thereby improving the interaction experience.
The touch device 120 may be provided with a vibration film (e.g., attached to an inner wall of the touch screen) to generate vibration in the entire area or a part of the touch region 130. In some embodiments, the diaphragm may be a piezoelectric actuation film to generate corresponding vibration feedback by receiving a touch operation.
In some embodiments, in the case that the touch operation is determined to be invalid, the processor may be further configured to re-determine the effective area 131 according to the preset effective area 131 and the action position before determining whether the action position is located in the effective area 131 of the touch area 130 of the touch device 120 next time, that is, re-determine the effective area 131 according to the operation habit of the user, so as to improve the intelligence of the home appliance 100 and improve the user experience.
Specifically, the processor may be configured to record an action position at which the touch operation is invalid and a corresponding action number within a set time range, and re-determine the effective area 131 according to a preset effective area 131 and the action position when the action number is greater than or equal to a preset number threshold; when the action times are less than the preset time threshold value, the effective area 131 is kept unchanged, so that the effective area 131 is prevented from being excessively enlarged, and the staggering rate of the door body is improved.
