The clothes of the embodiment do not need to be completely soaked in the cleaning tank 4, and only need to be contacted with the ultrasonic vibration end of the ultrasonic generating device 3 to reach resonance after being soaked, so that the effect of thorough cleaning is achieved. Because this scheme only needs to soak clothing, does not need to put ultrasonic generating device into liquid and produces resonance, consequently only need a small amount of liquid, the washing tank 4 that needs is also shallower, and its degree of depth only needs be greater than thicker clothing can. Therefore, the volume requirement of the cleaning tank 4 is small, and a good cleaning effect can be achieved only by a small amount of water, so that the occupied space can be saved, the water consumption can be greatly saved, and the cleaning process is convenient and quick.

The ultrasonic vibration end of the ultrasonic wave generating device 3 is contacted with the liquid level in the cleaning tank 4 or has a certain interval, and the interval is that when the upper surface of the laundry 8 is contacted with the ultrasonic vibration end, at least the lower surface of the laundry 8 is contacted with the liquid level of the cleaning liquid 9.

When the ultrasonic vibration end of the ultrasonic generating device 3 is in contact with the liquid level in the cleaning tank 4, the laundry 8 is completely immersed in the cleaning tank 4, and the upper surface of the laundry 8 is in contact with the ultrasonic vibration end. When the ultrasonic generating device 3 works, ultrasonic vibration directly reaches clothes, so that consumption of ultrasonic waves is reduced, meanwhile, the high-frequency ultrasonic vibration emitted by the ultrasonic generating device vibrates liquid soaked in the clothes 8 to be washed, a plurality of tiny high-frequency bubbles are generated, and the tiny bubbles continuously strike the surface and inner layer of the clothes to be washed and resonate with stains and the like on the surface and inner layer of the clothes to be washed, so that the stains fall off.

In addition, the ultrasonic generating device 3 can also move relative to the cleaning tank 4, and the ultrasonic vibration end can horizontally slide along the length direction of the cleaning tank 4, so that the ultrasonic generating device can automatically move to clean stains with larger area, such as collars and the like.

The ultrasonic wave generating device 3 can also rotate above the cleaning tank 4 in a lifting and falling way, so that the clothes can be conveniently put into the cleaning tank 4 for infiltration, and the cleaning treatment of the cleaning tank 4 and the like is also convenient. When the clothes are needed to be placed, the ultrasonic generating device 3 is rotated upwards and lifted; after the placement, the ultrasonic generator 3 is rotated reversely, and the ultrasonic vibration end is directed to the cleaning tank 4 to prepare for cleaning.

In a further scheme, the ultrasonic vibration end of the ultrasonic generating device 3 can move up and down in the vertical direction, and the distance between the ultrasonic vibration end and the cleaning tank 4 is adjusted. At least two gears are arranged at the interval between the ultrasonic vibration end and the cleaning tank 4, and when the ultrasonic vibration end stretches below the liquid level, the ultrasonic vibration end directly vibrates the cleaning liquid 9 to clean rigid articles placed in the cleaning liquid 9; when the ultrasonic vibration end is spaced from the liquid surface, the ultrasonic vibration end is directly contacted with the clothes to vibrate and clean the clothes.

The liquid level in this solution can be the liquid level of the fixed height that the washing liquid 9 that sets up reaches after getting into washing tank 4, and the height of liquid level can be set up according to the specification size of washing tank 4. The ultrasonic vibration end can move up and down in the vertical direction, and the distance between the ultrasonic vibration end and the cleaning tank 4 can be adjusted, so that the cleaning objects can be adjusted according to the requirements.

Further, a plurality of ultrasonic vibrators are arranged, and the heights of the ultrasonic vibrators protruding out of the bottom surface of the shell are consistent.

The ultrasonic vibrators act together, so that the ultrasonic contact area can be increased, and the cleaning efficiency is improved. When the heights of the ultrasonic vibrators protruding out of the bottom surface of the shell are consistent, a resonance plane can be formed, and a good resonance effect is achieved. The heights of the ultrasonic vibrators protruding from the bottom surface of the shell can be inconsistent, so that a plurality of resonance surfaces are formed to act together.

Meanwhile, the arrangement mode of the ultrasonic vibrators has a great influence on the cleaning effect and the cleaning efficiency of clothes. The plurality of ultrasonic vibrators may be staggered or uniformly distributed, and may be set according to the area of the ultrasonic vibration end and the power of the ultrasonic generator 3.

In a preferred embodiment, a plurality of ultrasonic transducers are arranged in a plurality of rows along the longitudinal direction of the cleaning tank 4, and the ultrasonic transducers in each row are staggered in the front-rear direction.

The water inlet stage is a water storage device, namely, the process that water in a water storage box enters a cleaning tank, the ultrasonic cleaning stage is a process that an ultrasonic generating device generates ultrasonic vibration to clean the laundry, and the process lasts for a certain time. The drainage stage is the process of draining the washing liquid in the washing tank into the waste water box, so that the whole washing process is completed.

For the ultrasonic cleaning device capable of automatically feeding water, whether the water storage device has insufficient water quantity can be judged by only detecting the liquid level; for the ultrasonic cleaning device with water inflow control, various conditions can be judged by detecting the liquid amount or detecting the liquid level and the liquid amount simultaneously.

In the stage of intaking, ultrasonic cleaning device real-time supervision washing tank liquid level's height and get into the liquid measure in the washing tank to cooperate the detection time to judge whether the liquid level in the washing tank satisfies the liquid level that the clothing was soaked, if do not satisfy then send suggestion or report to the police, thereby can guarantee abluent going on smoothly, reduce clothing and ultrasonic cleaning device wearing and tearing, improve the cleaning performance.

In a further scheme, in the water inlet stage of the ultrasonic cleaning device, if the liquid level and/or the liquid amount in the cleaning tank reach the set value in the set time, the ultrasonic cleaning stage is started, vibration cleaning is started, and if the liquid level and/or the liquid amount in the cleaning tank does not reach the set value, a user is prompted that the water amount in the water storage device is insufficient.

The ultrasonic cleaning device is started to start the cleaning process, and firstly, water in the water storage box enters the cleaning tank, namely, the water inlet stage. At this stage, the level of the liquid in the washing tank is monitored by timing and in real time and/or the amount of liquid entering the tank is detected to ensure that sufficient water/washing liquid has entered the tank to infiltrate the laundry. Through the set time, the liquid level and/or the liquid amount in the time period reaches the set value, if the set time is not exceeded and the set value is not reached, the lack of a water inlet source is indicated, the water storage device is indicated to have insufficient water amount, or an alarm is sent to remind a user that water is needed to be replenished. If the ultrasonic cleaning is achieved, the ultrasonic cleaning stage is directly carried out for cleaning.

Further, the liquid level and/or the liquid amount in the cleaning tank is detected in real time in the water inlet stage, if the liquid level and/or the liquid amount does not reach a set value, whether the set time is reached or not is judged, if the set time is not reached, water inlet is continued, and if the set time is reached or exceeded, a user is prompted that the water amount in the water storage device is insufficient.

The flow detection means may be a flow meter which meters the amount of water/wash liquid entering the wash tank from the water storage means. If the detected quantity of the liquid entering the cleaning tank is smaller than the set value within a certain time, the water inlet source is small, and the water quantity in the water storage device is insufficient, a prompt or an alarm is sent, a user is reminded of timely adding water, and the liquid level in the cleaning tank can be guaranteed to fully infiltrate clothes.

In a further scheme, in the water inlet stage, when the set time is reached or exceeded, the liquid quantity entering the cleaning tank and the liquid level in the cleaning tank, which are detected in real time, are respectively lower than the set value, and a user is prompted that the water quantity in the water storage device is insufficient.

In order to ensure the accuracy of judgment and avoid false alarm, in the scheme, in the water inlet stage, when the detected liquid amount and liquid level are lower than the set values, the water storage device is judged to be insufficient in water amount, and then a user is prompted.

Further, when the liquid level in the cleaning tank is lower than the set value when the liquid level in the cleaning tank reaches or exceeds the set value in the set time, judging that the cleaning tank leaks water, and simultaneously prompting or alarming;

or when the liquid amount entering the cleaning tank is detected to reach a set value in a set time, obtaining a theoretical liquid level in the cleaning tank according to the liquid amount entering the cleaning tank and the shape and volume analysis of the cleaning tank; if the actual liquid level of the cleaning tank monitored in real time is lower than the theoretical liquid level, judging that the cleaning tank leaks water, and simultaneously prompting or alarming.

The cleaning tank, the water storage device and the like of the ultrasonic cleaning device can be detachable. When the user installs the water tank, the water tank is possibly not installed in place, and water leakage and the like occur. In order to avoid water leakage caused by misoperation, the ultrasonic cleaning device of the scheme judges that the cleaning tank leaks water when the detected liquid amount entering the cleaning tank reaches a set value but the actual liquid level in the cleaning tank does not reach the set value, and reminds a user to check, so that the phenomenon that clothes cannot be soaked due to the fact that the liquid level in the cleaning tank cannot reach a preset value can be avoided, the influence of water leakage on the surrounding environment can be avoided, the cleaning effect is guaranteed, and the user experience can be improved.

Further, the control method further includes: after the liquid level in the water inlet stage reaches a set value, entering an ultrasonic cleaning stage, and monitoring the liquid level in the cleaning tank in real time in the ultrasonic cleaning stage; when the liquid level is lower than the set value in a period of time, the user is prompted that the water quantity in the water storage device is insufficient.

In this scheme, at ultrasonic cleaning stage, after clothing infiltration part liquid, ultrasonic cleaning stage real-time supervision washing tank liquid level ensures the cleaning process in, and the liquid level in the washing tank remains at the liquid level of predetermineeing all the time to guarantee the cleaning performance of clothing, avoid the liquid level to reduce the back, ultrasonic cleaning causes wearing and tearing to the clothing. When the liquid level is lower than the set value in a period of time, the fact that the liquid level is not supplemented due to insufficient water in the water storage device is judged, and then a prompt is sent to a user to timely supplement the water in the water storage box.

In a further specific scheme, in the ultrasonic cleaning stage, when the liquid level monitored in real time is lower than a set value, the liquid level is controlled to reach the set value by controlling water inflow; if the liquid level in the cleaning tank is detected to be lower than the set value in a period of time, prompting a user that the water quantity in the water storage device is insufficient.

When the liquid level monitored in real time is lower than a set value, the control device of the ultrasonic cleaning device firstly controls the control valve on the water inlet pipeline to be opened, the water inlet pipeline is used for feeding water into the cleaning tank, and the water inlet is stopped when the liquid level reaches a preset value. The water inlet is controlled to be opened and closed for a plurality of times, so that the liquid level in the cleaning tank is maintained at a set value in the ultrasonic cleaning stage. The ultrasonic cleaning device with automatic water inlet does not need to be controlled. When the liquid level in the cleaning tank is detected to be lower than the set value in a period of time, the user is prompted that the water quantity in the water storage device is insufficient.

The "preset value", "set time", "period of time" and the like described in this embodiment may be preset in the control device according to the model, size, washing program and the like of the ultrasonic cleaning device, or may be set by the user.

Further, in order to detect the drainage condition, the drainage abnormality is found in time, when the ultrasonic cleaning device drains water, the liquid level in the cleaning tank is monitored in real time, and if the liquid level in the cleaning tank is higher than a set value within a certain period of time after the water drainage, the drainage abnormality is judged, and meanwhile a prompt or an alarm is sent.

In the drainage process, the ultrasonic cleaning device detects the liquid level in the cleaning tank, if the liquid level does not drop or drops less after draining for a certain time, the problem of unsmooth drainage exists, the abnormal drainage is judged, the user is reminded to check, and the smooth cleaning is ensured.

Preferably, in a certain time after draining, if the liquid level in the cleaning tank is lower than a set value, stopping draining;

in the preferred scheme, when the liquid level in the cleaning tank is detected to be empty, the water discharge is stopped, so that the water in the cleaning tank is ensured to be discharged cleanly, and the ultrasonic cleaning device is kept clean and dry when empty.

In order to wash the cleaning tank, when the liquid level in the cleaning tank is lower than a set value, the water draining is stopped, then water is fed for a certain time, and after water feeding is stopped, the water draining is performed until the cleaning tank is emptied.

In addition, the embodiment also provides an ultrasonic cleaning device, which comprises an ultrasonic generating device, a cleaning tank and a water storage device for providing water for the cleaning tank, wherein in the water inlet stage, the liquid level and/or the liquid quantity in the cleaning tank are detected, and if the detected liquid level and/or liquid quantity is lower than a set value, a prompt or an alarm is given.

In a specific scheme, because the volume of the cleaning tank of the ultrasonic cleaning device is smaller, the liquid level of the cleaning liquid required in the cleaning tank is lower, and in order to accurately detect the liquid level in the cleaning tank, a detection device can be arranged in the cleaning tank and used for detecting the liquid level in the tank or the water quantity in the tank.
