The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1

As shown in fig. 1 to 6, an object of the present invention is to provide a washing machine with a partial pre-washing function. The washing machine comprises an ultrasonic washing device; the ultrasonic washing device comprises an ultrasonic generating device 6 and a washing tank 7 which are connected with each other and are positioned at the lower part of the ultrasonic generating device 6, and the ultrasonic generating device and the washing tank are connected with each other through a rotatable connecting device 5. The ultrasonic washing device is rotatably connected with the control panel seat 1 of the washing machine through the rotatable connecting device 5. The control panel base 1 is provided with a containing space 3 for containing the ultrasonic washing device. As shown in fig. 1 and 3, the ultrasonic cleaning device is provided in the accommodation space 3 so as to be rotatable in and out.

The ultrasonic washing device independently performs pretreatment of clothes or washing of the clothes in an ultrasonic washing mode; the ultrasonic washing device can be arranged on the washing machine in a hidden way by utilizing the accommodating space 3. The rotatable connecting means 5 in this embodiment is connected to the bottom surface of the accommodating space 3, and the ultrasonic wave generating means 6 can rotate around the rotatable connecting means 5 to rotate in/out of the accommodating space 3 through the accommodating space opening 9.

As shown in the figure, the accommodating space 3 is recessed from the upper surface of the control panel 1 and located between the clothes input opening 2 of the control panel 1 and the peripheral wall 4 of the control panel, the sidewall of the accommodating space 3 is opened at the clothes input opening 2, and the ultrasonic washing device is screwed into/out of the accommodating space through the accommodating space opening 9.

Preferably, the rotatable connecting means 5 in this embodiment is a rotating shaft connecting means connected to the bottom surface of the accommodating space 3.

In order to make it possible to hide the ultrasonic cleaning device after it has been screwed into the receiving space 3, the width of the ultrasonic generator 6 in this embodiment is not greater than the width of the receiving space 3, and the width of the receiving space 3 is the distance between the receiving space opening 9 of the receiving space and the side wall of the receiving space 3 opposite to the opening. Due to the design, after the ultrasonic wave generating device 6 is completely screwed into the accommodating space 3, the clothes throwing-in opening 2 cannot be shielded, and the requirement of throwing amplified clothes by the washing machine is met. Further, the total width of the ultrasonic cleaning device including the cleaning tank 7 is smaller than the width of the accommodating space 3, so that the shielding effect of the equipment is improved.

In order to further optimize the hiding effect of the accommodating space 3 for the ultrasonic washing device, as shown in fig. 5, the height of the ultrasonic washing device is not higher than the height of the side wall of the accommodating space. The ultrasonic washing device does not affect the opening and closing of the upper cover of the washing machine, and the ultrasonic washing device can be completely shielded after the upper cover of the washing machine is closed. Thereby ensuring the integrity of the external appearance of the washing machine.

As shown in fig. 1, 3 and 6, the ultrasonic washing device is provided with a limit position and a working position according to the position relationship between the ultrasonic generator and the accommodating space. As shown in fig. 3, when the ultrasonic wave generating device 6 is completely screwed into the accommodating space 3, the ultrasonic wave washing device is in a limit position; as shown in fig. 1 or fig. 6, when the ultrasonic wave generating device 6 is rotated around the rotatable connecting device 5 and is at least screwed out of the accommodating space 3, the ultrasonic washing device is in the working position. The ultrasonic washing device provides a partial pre-washing function to the laundry when in the working position.

When the rotatable connecting device of the ultrasonic washing device is positioned on the side walls of the left side and the right side of the control panel seat, the rotating angle of the ultrasonic washing device is not more than 180 degrees when the ultrasonic washing device is switched from the limiting position to the working position.

In the embodiment shown in the figures, when the rotatable device is arranged at one corner of the control panel seat of the washing machine, the rotation angle of the ultrasonic washing device is not more than 90 degrees when the ultrasonic washing device is switched from the limit position to the working position.

As shown in fig. 1, 3 and 6, the clothes inlet 2 of the control panel base of the present embodiment is located in the middle of the control panel base 1 with a quadrilateral outer edge of the cross section of the overall peripheral wall 4, and the control panel 8 of the washing machine is installed on the control panel base 1 and is close to one side of the quadrilateral, and the peripheral wall corresponding to the side is a first side; the accommodating space is positioned between the peripheral wall of the control panel seat opposite to and/or adjacent to the first side surface and the clothes input opening. That is, the ultrasonic cleaning device is placed inside the seat on the side other than the side where the control panel is located, because there are many control lines or interfaces in the space of the sidewall where the control panel is located, and the internal accommodation space is very limited, which is not favorable for providing the accommodation space for the ultrasonic cleaning device. Also, from the viewpoint of convenience of use, the arrangement of placing the rotatable means in any one of the two corners of the control panel base close to the back plate as in the present invention enables the accommodation space to be provided on the upper surfaces of both sides and the back side of the control panel base, making full use of the relatively large installation space at the corners of the panel base, thereby making the installation structure more compact.

Example 2

This embodiment is a supplement to embodiment 1, and as shown in fig. 1 to 5, this embodiment discloses a washing machine with a partial pre-washing function to which the control panel of the washing machine described in embodiment 1 is applied. The washing machine includes an ultrasonic washing device as in embodiment 1; the control panel base 1 is provided with a containing space 3 for containing the ultrasonic washing device, and the ultrasonic washing device can be arranged in the containing space 3 in a screwing-in/screwing-out mode.

The washing barrel and the ultrasonic washing device of the washing machine can work independently respectively, the washing barrel is used for washing a large amount of whole clothes, the ultrasonic washing device is mainly used for washing parts, such as collars, cuffs and clothes edges, of the clothes, which are not easy to wash, and performing pretreatment or independent ultrasonic washing, and can also be used for washing the clothes or the local stains of soft articles, so that the effect of quickly removing stubborn stains is achieved.

The washing machine of the present embodiment may be any one of a drum washing machine, a pulsator washing machine, a twin drum washing machine, and the like.

For convenience of description, the present embodiment takes a pulsator washing machine as an example for explanation:

the ultrasonic generator 6 in this embodiment is fixedly connected to the cleaning tank 7 through the rotatable connecting device 5, and the cleaning tank 7 moves integrally with the ultrasonic generator 6 and maintains a fixed relative position relationship therebetween. As shown in fig. 1 to 5, the ultrasonic cleaning apparatus is provided with a limit position and a working position according to a positional relationship between the ultrasonic generator 6 and the housing space 3. As shown in fig. 3, when the ultrasonic wave generating device 6 is completely screwed into the accommodating space 3, the ultrasonic wave washing device is in a limit position; as shown in fig. 1 or fig. 6, when the ultrasonic wave generating device is rotated around the rotatable connecting device and is at least screwed out of the accommodating space, the ultrasonic wave washing device is in a working position for providing ultrasonic pre-washing for the clothes.

According to the washing machine, the ultrasonic washing device is mounted on the washing machine in a hidden mode, when the washing machine is not used, the ultrasonic washing device is hidden in the containing space of the control panel seat of the washing machine, the appearance of the washing machine is complete, and the ultrasonic washing device cannot be seen; when it is necessary to use the ultrasonic cleaning apparatus, the ultrasonic cleaning apparatus is rotated out to expose the ultrasonic generator 6 and the cleaning tank 7, and ultrasonic cleaning is performed. 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 scheme, the ultrasonic washing device comprises an ultrasonic generating device 6 and a washing tank 7 for containing washing liquid, wherein the ultrasonic generating device 6 is provided with an ultrasonic generating device for generating vibration, and the ultrasonic generating device faces the washing tank 7; the ultrasonic wave generating device 6 and the cleaning tank 7 are rotatably mounted on the control panel base 1 through the rotatable connecting device 5 so as to be unscrewed for ultrasonic cleaning or retracted for hiding according to use requirements.

The ultrasonic cleaning apparatus of the present embodiment includes an ultrasonic generator 6 and a cleaning tank 7, which are vertically disposed in correspondence with each other. After at least partial clothes to be washed are placed between the ultrasonic wave generating device 6 and the washing tank 7, the clothes to be washed are soaked by the washing liquid in the washing tank 7, and the clothes can be completely soaked or partially soaked; the upper surface of the soaked clothes to be washed is contacted with the ultrasonic generating device of the ultrasonic generating device 6, when the ultrasonic generating device 6 works, the stains of the clothes to be washed and the ultrasonic generating device 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 effect of removing the stains is better.

The clothes do not need to be completely soaked in the cleaning tank 7, and only need to be contacted with the ultrasonic wave generating device of the ultrasonic wave generating device 6 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 wave 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 7 is shallow, and the depth of the cleaning tank is only needed to be larger than that of the thicker clothes. Therefore, the volume of the cleaning tank 7 is very 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 fast.

The ultrasonic wave generating means of the ultrasonic wave generating means 6 is in contact with or has a certain distance from the liquid level in the washing tub 7, said distance being such that at least the lower surface of the laundry is in contact with the liquid level of the washing liquid when the upper surface of the laundry is in contact with the ultrasonic wave generating means.

The liquid level of this scheme can be the liquid level of the fixed height that reaches after washing liquid that sets for gets into washing tank 7, and the height of liquid level can be set for according to the specification size of washing tank 7.

When the ultrasonic wave generating means of the ultrasonic wave generating means 6 is brought into contact with the liquid surface in the cleaning tank 7, the laundry is completely soaked in the cleaning tank 7 while the upper surface of the laundry is brought into contact with the ultrasonic wave generating means. When the ultrasonic wave generating device 6 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 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 to generate resonance with stains on the surface and the inner layer of the clothes to be washed, so that the stains fall off.

When the ultrasonic wave generating device of the ultrasonic wave generating device 6 has a certain distance with the liquid level in the washing tank 7, the distance needs to be the largest enough to allow the lower surface of the laundry to contact with the liquid level of the washing liquid when the upper surface of the laundry contacts with the ultrasonic wave generating device. Therefore, the clothes to be washed can be ensured to be continuously soaked in the washing liquid, so that resonance is achieved during ultrasonic work, and the washing effect is achieved.

Example 3

The present embodiment is different from embodiment 2 in that, as shown in fig. 1 and 3 and fig. 6, the ultrasonic wave generating device of the present embodiment is connected with the cleaning tank through a movable connecting device, so that at least two different relative positions between the ultrasonic wave generating device 6 and the cleaning tank 7 are realized. As shown in fig. 6, the ultrasonic wave generating device 6 and the cleaning tank 7 in the present embodiment are connected by the rotatable device 5. The ultrasonic wave generating device has a first working position which is positioned right above the projection of the cleaning tank and is shown in figure 1, and a second working position which is formed by rotating the ultrasonic wave generating device around the rotatable device and has an included angle with the cleaning tank and is shown in figure 6.

The arrangement enables the ultrasonic wave generating device to have more new choices when the clothes are pre-washed, when large clothes exist, the ultrasonic wave generating device can be positioned at the second working position through the rotation of the rotatable connecting device, and the ultrasonic wave generating device 6 and the washing tank 7 are staggered mutually at the moment, so that the pre-washing operation of the clothes can be more conveniently processed.

The working process is as follows:

when a user needs to carry out ultrasonic washing on clothes, the movable mechanism is pulled out/turned over manually to take out the ultrasonic washing device, or corresponding keys are operated, and the washing machine automatically pops out the hidden ultrasonic washing device. After a user starts the ultrasonic washing device, the water supply box or the water inlet pipe of the washing tank conveys washing liquid into the washing tank, the liquid level in the washing tank stops after reaching a certain height, the user puts local clothes into the washing tank to wash, and the washing liquid is discharged after the washing liquid is washed. Or the washing tank is filled with water and the pipeline discharges the liquid into an inner barrel or a drain pipe of the washing machine, so that the flowing liquid is formed in the washing tank. 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 liquid inlet speed and the liquid outlet speed need to keep the liquid flowing, and meanwhile, the washing liquid buffered in the washing tank soaks or partially soaks the clothes to be washed. In addition, the flowing liquid also enhances the resonance effect, and water is not wasted due to the small volume and shallow inside of the cleaning tank.
