Washing machine with ultrasonic pre-washing function and control method thereof

Abstract

The invention belongs to the technical field of clothes washing, and aims to solve the problems of how to ensure that the use of functions of washing, rinsing, dewatering and the like of a washing machine is not influenced after a push-pull type ultrasonic device structure is additionally arranged in the washing machine and how to more conveniently operate by a user when the washing machine is used. The invention provides a control method of a washing machine with an ultrasonic pre-washing function. The control method comprises the steps that the state of a start-stop key is obtained; if the state of the start-stop key is a selected state, obtaining the state of the ultrasonic function key and the position of the ultrasonic device; if the state of the ultrasonic function key is a non-selected state and the position of the ultrasonic device is a non-working position, executing a conventional washing program; the position where the ultrasonic device is pushed into the containing cavity is the non-working position of the ultrasonic device. According to the washing machine, the use of the functions of washing, rinsing, dewatering and the like of the washing machine can be prevented from being affected, and user operation can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of laundry washing, and specifically provides a washing machine with an ultrasonic pre-wash function and a control method thereof. Background technique [0002] Most washing machines can only clean the clothes as a whole, and cannot individually and specifically clean the stubborn and stained parts such as collars and sleeves. This can be achieved by increasing the detergent dosage, prolonging the washing time, and prolonging the soaking time before washing, etc. However, the above methods will inevitably lead to more serious wear and tear of the clothes and damage caused by the detergent. Therefore, an ultrasonic device is added to the washing machine so that the user can pre-wash the clothes before the normal washing, rinsing and other procedures. [0003] Initially, the ultrasonic device was fixed on the washing machine, whether it was used or not, it was always exposed, which easily caused dust to accum...
