Embodiment 1

As shown in FIG. 1 to FIG. 4, the present embodiment provides an ultrasonic cleaning device comprising an ultrasonic generating device 2 capable of generating ultrasonic waves and a cleaning tank 3 for holding a washing liquid 12, the ultrasonic generating device 2 being located above the cleaning tank 3. The ultrasonic vibration end of the ultrasonic generating device 2 faces the cleaning tank; the laundry 4 is placed between the ultrasonic generating device 2 and the washing tank 3 and is infiltrated by the washing liquid 12 while the upper surface of the laundry 4 and the ultrasonic generating device 2 The ultrasonic vibration end contacts.

The ultrasonic washing apparatus of this embodiment can clean some parts of the laundry that are not easily cleaned, such as collars, cuffs, edges of clothes, etc., and can also clean stains 13 of the articles of clothing or soft materials.

Both the ultrasonic generating device 2 and the cleaning tank 3 of the present embodiment can be mounted on the body 1 of the ultrasonic washing device, and are disposed correspondingly above and below. After at least part of the laundry 4 is placed between the ultrasonic generating device 2 and the washing tank 3, the laundry 4 is wetted by the washing liquid 12 in the washing tank 3, and may be completely wetted or partially infiltrated; The upper surface of the object 4 is in contact with the ultrasonic vibration end of the ultrasonic generating device 2, and when the ultrasonic generating device 2 is operated, the stain of the laundry 4 resonates with the ultrasonic vibration end, and the resonance can directly reach the deep layer of the clothing fiber, the surface of the laundry and the deep layer. Stubborn stains can fall with the resonance of ultrasonic vibration waves, so the effect of removing stains is better.

The laundry of the present embodiment does not need to be completely immersed in the cleaning tank 3, and only needs to be in contact with the ultrasonic vibration end of the ultrasonic generating device 2 to resonate after being infiltrated, thereby achieving the effect of thorough cleaning. Since the solution only needs to infiltrate the laundry, it is not necessary to place the ultrasonic generating device in the liquid to generate resonance, so only a small amount of liquid is needed, and the required cleaning tank 3 is also shallow, and the depth only needs to be larger than the thicker clothes. Therefore, the volume requirement of the cleaning tank 3 is small, and only a small amount of water is required to achieve a good cleaning effect, which can save space and save water consumption, and the cleaning process is convenient and quick.

The ultrasonic vibration end of the ultrasonic generating device 2 is in contact with the liquid surface in the cleaning tank 3 or has a certain distance, and the spacing satisfies at least when the upper surface of the laundry 4 is in contact with the ultrasonic vibration end, at least under the laundry 4 The surface is in contact with the liquid surface of the washing liquid 12.

When the ultrasonic vibration end of the ultrasonic generating device 2 comes into contact with the liquid surface in the washing tank 3, the laundry 4 is completely wetted in the washing tank 3 while the upper surface of the laundry 4 comes into contact with the ultrasonic vibration end. When the ultrasonic generating device 2 is in operation, the ultrasonic vibration directly reaches the clothes, which reduces the consumption of the ultrasonic waves, and the high-frequency ultrasonic waves emitted by the ultrasonic generating device vibrate the liquid infiltrated into the laundry 4, generating many small high-frequency bubbles, which are continuously hit. The surface and the inner layer of the washed laundry resonate with the stains on the surface of the laundry and the inner layer to cause the stain to fall off.

After the laundry 4 is wetted in the cleaning tank 3, the upper surface needs to be in contact with the ultrasonic vibration end, and the ultrasonic generating device 2 is located above the inside of the cleaning tank 3. First, the ultrasonic vibration wave can be ensured to act on the laundry in the cleaning tank 3 to the maximum extent. The stained area ensures the decontamination effect, and the second is to ensure that the washing liquid 12 is concentrated in the washing tank 3 without splashing into other areas.

In addition, the ultrasonic generating device 2 can also move relative to the cleaning tank 3, and the ultrasonic vibration end can be horizontally slid along the length direction of the cleaning tank 3, so that it can be automatically moved to clean a large-area stain such as a collar.

The ultrasonic generating device 2 can also be lifted and lowered above the washing tank 3, so that it is easier to infiltrate the laundry into the washing tank 3, and it is also convenient for the cleaning process of the washing tank 3 and the like. When the laundry needs to be placed, the ultrasonic generating device 2 is rotated upward and raised; after the placement is completed, the ultrasonic generating device 2 is dropped in the opposite direction, and the ultrasonic vibration end is directed toward the cleaning tank 3 to prepare for the cleaning operation.

In a further aspect, the ultrasonic vibration end of the ultrasonic generating device can move up and down in the vertical direction to adjust the spacing between the ultrasonic vibration end and the cleaning tank. The distance between the ultrasonic vibration end and the cleaning tank is at least two. When the ultrasonic vibration end extends below the liquid surface, the ultrasonic vibration end directly vibrates the washing liquid, and the rigid article placed in the washing liquid is cleaned; the ultrasonic vibration end and the liquid surface have At certain intervals, the ultrasonic vibration end is in direct contact with the clothes, and the clothes are vibrated and cleaned.

The liquid level of the solution can be a fixed level of liquid level reached after the set washing liquid enters the washing tank, and the height of the liquid surface can be set according to the size of the washing tank. The ultrasonic vibration end can move up and down in the vertical direction, and the spacing between the ultrasonic vibration end and the cleaning tank can be adjusted to facilitate adjustment according to items to be cleaned. The movement of the ultrasonic vibration end in the vertical direction may be set to a fixed pitch of several steps, or may be set to be arbitrarily adjustable within a certain range of height. The ultrasonic vibration end can be inserted into the washing liquid at the minimum, and is used for cleaning small rigid articles such as glasses and accessories to achieve a good cleaning effect. When cleaning the clothes, the ultrasonic vibration end is raised upwards so that the ultrasonic vibration end is only in contact with the liquid surface or has a certain interval, and is directly in contact with the wetted clothes, vibrating and washing the clothes, thereby simultaneously achieving both rigid articles and flexible clothes. Achieve good washing results.

The laundry 4 is contacted, and then spreads to the surface of the laundry 4 and the deep immersion liquid, and the microbubbles are generated to hit the surface and the deep layer of the washed laundry, so that the stain is expected to reach a resonance drop effect.

In a further aspect, the ultrasonic vibrator 6 is provided in plurality, and the plurality of ultrasonic vibrators 6 protrude from the bottom surface of the casing 7 at a uniform height.

The plurality of ultrasonic vibrators 6 work together to increase the ultrasonic contact area and improve the cleaning efficiency. When the height of the ultrasonic vibrator 6 protruding from the bottom surface of the casing 7 is uniform, a resonance plane can be formed to achieve a better resonance effect. The height of the ultrasonic vibrator 6 protruding from the bottom surface of the casing 7 may also be inconsistent, forming a plurality of resonance faces, which work together.

At the same time, the arrangement of the plurality of ultrasonic vibrators 6 has a great influence on the cleaning effect and cleaning efficiency of the clothes. The plurality of ultrasonic vibrators 6 may be arranged in a staggered manner or uniformly distributed, and may be set according to the area of the ultrasonic vibration end and the power of the ultrasonic generating device 2.

As shown in FIG. 2, as a more preferable embodiment, the plurality of ultrasonic vibrators 6 are arranged in a plurality of rows along the longitudinal direction of the cleaning tank 3, and the ultrasonic vibrators 6 between the rows are alternately distributed. In this way, a smaller contact area with the clothes can be realized with fewer ultrasonic vibrators 6, thereby saving cost and ensuring cleaning efficiency.
