In the above-mentioned embodiment, the "normal washing program" specifically refers to a program related to washing clothes, which can be executed by the laundry appliance and does not involve the ultrasonic device 1, such as a washing program, a rinsing program, a dewatering program, a draining program of the laundry appliance having only a washing function, a drying program of the laundry appliance having washing and drying functions, and the like. The "normal washing program starting instruction" is an instruction for starting any one of the above-listed washing programs.
The first obtaining module is any one of instruction input modules capable of obtaining a program starting instruction, such as a touch panel, an operation button key, a voice instruction receiving device and the like of laundry equipment. The second acquiring means is any means capable of acquiring the position of the ultrasound device 1, such as a distance sensor, an image acquiring device such as a camera or a video camera, and acquires the position state of the ultrasound device 1 by acquiring the distance between an arbitrary position on the ultrasound device 1 and a reference point of the housing chamber or acquiring an image of the position of the ultrasound device 1 with respect to the housing chamber.
