Therefore, the appearance integrity of the washing machine can be kept, the obstruction and the influence on the normal washing of the washing machine can be avoided, and the use of a user is facilitated.

In a further aspect, the ultrasonic washing apparatus includes a body 100 having an ultrasonic generating device 200 and a washing tank 400 for containing a washing liquid 7, the ultrasonic generating device 200 has an ultrasonic vibrating end for generating vibration, the ultrasonic vibrating end faces the washing tank 400; the body 100 is rotatably, or slidably, or liftably and lowerably mounted in the housing 1 or on the tray 3 of the washing machine through the movable mechanism 8, so as to be extended for ultrasonic washing or retracted for hiding according to the use requirement.

The ultrasonic cleaning apparatus of the present embodiment includes an ultrasonic generator 200 and a cleaning tank 400, which are vertically disposed in correspondence to each other. After at least partial clothes 5 to be washed are placed between the ultrasonic wave generating device 200 and the washing tank 400, the clothes 5 to be washed are soaked by the washing liquid 7 in the washing tank 400, and can be completely soaked or partially soaked; the upper surface of the soaked clothes 5 to be washed is contacted with the ultrasonic vibration end of the ultrasonic generating device 200, when the ultrasonic generating device 200 works, the stains of the clothes 5 to be washed and the ultrasonic vibration end generate resonance, the resonance can directly reach the deep layer of the clothes fiber, and stubborn stains on the surface and the deep layer of the clothes can fall off along with the resonance of the ultrasonic vibration wave, so that the stain removing effect is better.

The laundry is not required to be completely soaked in the cleaning tank 400, and the laundry is only required to be contacted with the ultrasonic vibration end of the ultrasonic wave generating device 200 after being soaked to achieve resonance, so that the effect of thorough cleaning is achieved. Because the scheme only needs to soak the clothes, the ultrasonic generating device does not need to be placed in liquid to generate resonance, only a small amount of liquid is needed, the needed cleaning tank 400 is shallow, and the depth of the cleaning tank is only needed to be larger than that of the thicker clothes.

When the ultrasonic wave generating device 200 works, the ultrasonic wave vibration directly reaches the clothes, so that the consumption of the ultrasonic wave is reduced, meanwhile, the high-frequency ultrasonic wave generated by the ultrasonic wave vibrates the liquid soaked in the clothes 5 to be washed, a plurality of tiny high-frequency bubbles are generated, and the tiny bubbles continuously hit the surface and the inner layer of the clothes to be washed, generate resonance with stains on the surface and the inner layer of the clothes to be washed, and enable the stains to fall off.

When the ultrasonic vibration end of the ultrasonic wave generating device 200 has a certain distance from the liquid level in the washing tank 400, the distance needs to be the largest enough to allow the lower surface of the laundry 5 to contact the liquid level of the washing liquid 7 when the upper surface of the laundry 5 contacts the ultrasonic vibration end. Therefore, the clothes 5 to be washed can be ensured to be continuously soaked in the washing liquid 7, so that resonance is achieved during ultrasonic work, and the washing effect is achieved.

For the convenience of the user, the ultrasonic washing device is installed on the upper part of the washing machine through a movable mechanism 8, preferably installed in the shell 1 or the tray 3 of the washing machine, and the movable mechanism 8 is connected with the shell 1 or the tray 3 of the washing machine in a rotatable, or push-pull, or lifting manner, so as to drive the ultrasonic washing device to be exposed for ultrasonic washing or to be retracted and hidden.

In a further scheme, the washing machine is provided with a main water inlet pipeline which is used for feeding water into a washing barrel 2 of the washing machine and feeding water into a detergent box of the washing machine, so that detergent, softener and the like in the detergent box are brought into the washing barrel 2, and the whole piece of clothes is cleaned. The main water inlet pipeline is arranged at the upper part of the washing machine.

The ultrasonic washing device of the scheme is provided with a water supply box or a washing tank 400 water inlet pipeline. If a water inlet pipeline of the cleaning tank 400 is arranged, the upstream of the water inlet pipeline of the cleaning tank 400 is communicated with a main water inlet pipeline of the washing machine, and the downstream of the water inlet pipeline of the cleaning tank 400 is communicated with the cleaning tank 400. The water inlet pipeline of the cleaning tank 400 is preferably a flexible slender pipe, and a certain length is reserved, so that the movement of the ultrasonic cleaning device is not influenced.

After the operation of the user, the control unit controls the driving mechanism to drive the movable mechanism 8 to automatically turn over or pop up/retract, so that the exposure and the retraction of the ultrasonic washing device are automatically controlled.

The working process is as follows:

when a user needs to carry out ultrasonic washing on clothes, the movable mechanism 8 is pulled out/turned over manually to take out the ultrasonic washing device, or corresponding keys are operated, and the washing machine automatically pops up the hidden ultrasonic washing device. After the user starts the ultrasonic washing device, the water supply box or the water inlet pipe of the washing tank 400 conveys the washing liquid 7 to the washing tank 400, the liquid level in the washing tank 400 is stopped after reaching a certain height, the user puts local clothes in for washing, and the washing liquid 7 is discharged after the washing is finished. Or the washing tub 400 is filled with water and the pipe discharges the liquid into the inner tub of the washing machine or the drain pipe, forming a flowing liquid in the washing tub 400. Therefore, when the ultrasonic vibration enables the stains to fall off in a resonant mode, the falling stains can be washed away by the flowing liquid, and a better washing effect is achieved. The speed of the liquid inlet and outlet is required to keep the liquid flowing, and the washing liquid 7 buffered in the washing tank 400 soaks or partially soaks the laundry 5. In addition, the flowing liquid also enhances the resonance effect, and since the cleaning tank 400 has a small volume and a shallow interior, water is not wasted.
