[0002] The utility model patent of Chinese patent announcement number CN217678105U discloses an external ultrasonic washing machine, including a washing machine box, wherein a pre-wetting device, a plurality of sequentially arranged drum boxes and a vacuum water absorption device are sequentially arranged in the washing machine box along the cloth conveying direction, wherein the drum box is arranged at the inner bottom of the washing machine box, and a U-shaped drum groove is opened at the top of the drum box, and a drum is rotatably installed in the drum groove, and a plurality of ultrasonic vibrators are distributed in an annular manner on the outer wall of the bottom of the drum groove, and the plurality of ultrasonic vibrators release ultrasonic waves in the direction of the drum, and ultrasonic vibration cleaning is performed on the cloth close to the outer wall of the drum. When the device is used, the ultrasonic generator emits a high-frequency oscillation signal, which is then converted into a high-frequency mechanical oscillation by a transducer and propagated into the cleaning liquid, and the shock wave generated by the "cavitation effect" of ultrasonic waves in the liquid is used to remove the dirt on the surface of the printed and dyed fabric, so as to achieve the purpose of cleaning the printed and dyed fabric. However, due to the thin thickness of the fabric, the ultrasonic energy is mostly absorbed by the liquid in the washing box, resulting in large energy loss, and there is still a large room for improvement in energy utilization. On the other hand, the ultrasonic vibrator is installed on the inner bottom of the cleaning cabinet, which makes maintenance very inconvenient.

[0003] The utility model patent with Chinese patent announcement number CN215366350U discloses an ultrasonic washing machine, which has an ultrasonic vibration plate vertically arranged above the washing tank roller, and uses the ultrasonic vibration plate to cavitationally wash the fabrics on both sides. It has a simple structure, is easy to install, has low manufacturing costs, and does not require lying on the inner bottom of the washing machine box during maintenance, which makes maintenance more convenient. However, in this structure, the fabrics on both sides of the ultrasonic vibration plate are free in the water and will float with the ultrasonic source, resulting in a weakened ultrasonic force and poor actual washing effect.

[0004] In view of this, it is urgent to innovate the structure of ultrasonic washing machines to improve energy utilization. Utility Model Content

[0005] The utility model aims to provide an ultrasonic water cleaning device.

[0006] The technical solution for achieving the purpose of the utility model is: an ultrasonic water washing device, which includes a water washing tank, in which a cloth guide roller unit is installed, the cloth guide roller unit includes two groups of cloth guide roller groups arranged front and back in the cloth feeding and discharging directions, the cloth guide roller group close to the cloth feeding side is the front cloth guide roller group, and the cloth guide roller group close to the cloth discharging side is the rear cloth guide roller group, the front cloth guide roller group includes several front cloth guide rollers, the rear cloth guide roller group includes several rear cloth guide rollers, a support member for guiding and supporting the fabric is arranged between the front cloth guide roller group and the rear cloth guide roller group, the fabric passes through the support member between each of the front cloth guide rollers and each of the rear cloth guide rollers, and reciprocates back and forth around the same section of the support member and each of the front cloth guide rollers and each of the rear cloth guide rollers before the fabric is discharged, and an ultrasonic vibrator assembly is installed on one side of the fabric threading path on the support member.

[0007] Furthermore, several cloth guide roller units are installed in sequence from front to back in the washing tank, and a transition roller is installed between two adjacent cloth guide roller units. After the fabric is discharged from the front cloth guide roller unit, it bypasses the transition roller and enters another cloth guide roller unit adjacent to the cloth guide roller unit.

[0008] Furthermore, the support is in the shape of a plate or a roller, and a vibrator installation chamber is provided on the front side of the fabric on the support in the washing tank, and the ultrasonic vibrator assembly is installed in the vibrator installation chamber. When the ultrasonic wave hits the fabric surface, the other side of the fabric is blocked by the support, so the impact force is increased, thereby improving the washing efficiency.

[0009] Furthermore, the bottom of the washing tank body is recessed toward the top side of the washing tank body to form a maintenance channel, the maintenance channel is located between the front cloth guide roller group and the rear cloth guide roller group, the maintenance channel has a channel top and two channel side walls, the height of the maintenance channel is limited to the staff being able to pass through upright, the channel top is arched, the length of the channel top is greater than the width of the fabric, the channel top has a top inner wall and a top outer wall, the top inner wall is located in the washing tank body, the top inner wall forms the support, and the ultrasonic vibrator assembly is evenly installed on the top outer wall. The washing tank breaks through the rectangular box structure of the traditional washing tank, and is provided with a maintenance channel for the staff to pass upright, and the top inner wall is directly used as the winding surface of the fabric, which has a compact structure, high energy utilization, and a large maintenance operation space, and equipment maintenance is more convenient.

[0010] Furthermore, the maintenance passage passes through two side walls of the washing tank.

[0011] Furthermore, the contour of the top of the channel is in an arc shape, and the central angle of the arc at the top of the channel is greater than 180°, which can increase the contact area between the fabric and the inner wall of the top.

[0012] Furthermore, the channel side wall is arranged perpendicular to the horizontal plane.

[0013] The utility model innovates the traditional way of threading fabrics in ultrasonic washing machines. The fabric is wound back and forth between the front cloth guide rollers and the rear cloth guide rollers through the fabric support member and then discharged. The single-layer fabric when feeding in is stacked into multiple layers. The support member further reduces the spacing between the multiple layers of fabrics between the front cloth guide roller group and the rear cloth guide roller group. A rubbing effect is produced between the layers of fabric. The ultrasonic vibrator exerts a balanced force on the fabric, and the energy can be absorbed by the fabric as much as possible. The energy utilization rate is high, and compared with the traditional way of threading fabrics, about 70% of energy can be saved, which significantly improves the cleaning effect of the washing device.

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Example 1

[0020] like Figure 1As shown, an ultrasonic washing device comprises a washing tank 1, wherein two cloth guide roller units 2 are installed in the washing tank 1, wherein any cloth guide roller unit 2 comprises two cloth guide roller groups arranged front and back in the cloth feeding and cloth outlet directions, wherein the cloth guide roller group close to the cloth feeding side is a front cloth guide roller group 21, and the cloth guide roller group close to the cloth outlet side is a rear cloth guide roller group 22, wherein the front cloth guide roller group 21 comprises three front cloth guide rollers 211, and the rear cloth guide roller group 22 comprises three rear cloth guide rollers 221, and a plate-shaped support member 3 for guiding and supporting a fabric 100 is arranged between the front cloth guide roller group 21 and the rear cloth guide roller group 22, wherein the fabric 100 The fabric 100 passes through the support member 3 between each of the front cloth guide rollers 211 and each of the rear cloth guide rollers 221, and passes back and forth around the same section of the support member and each of the front cloth guide rollers and each of the rear cloth guide rollers before and after the fabric is discharged; a transition roller 4 is installed between two adjacent cloth guide roller units 2, and the fabric 100 passes through the transition roller 4 after being discharged from the front cloth guide roller unit 2 and enters the other cloth guide roller unit 2 adjacent to the cloth guide roller unit; a vibrator installation chamber 5 is provided on the front side of the fabric 100 on the support member 3 in the washing tank 1, and an ultrasonic vibrator assembly 6 is installed in the vibrator installation chamber 5.

[0021] During operation, the fabric passes through the fabric support between the front fabric guide roller and the rear fabric guide rollers in the fabric guide roller unit located at the front end, and reciprocates back and forth around the same section of the support and the front fabric guide rollers and the rear fabric guide rollers before being discharged. After being discharged, the fabric passes through the transition roller 4 and enters the fabric guide roller unit 2 located at the rear end. The fabric guide roller unit stacks the single-layer fabric into multiple layers when feeding the fabric. The support further reduces the spacing between the multiple layers of fabric between the front fabric guide roller group and the rear fabric guide roller group, and a rubbing effect is produced between the layers of fabric. Compared with the unsupported state of the fabric, the fabric will not float with the ultrasonic source, resulting in a weakening of the ultrasonic force. Therefore, the impact force of the shock wave generated by the "cavitation effect" of the ultrasonic wave in the liquid on the fabric can be increased. Moreover, after the fabric is stacked in multiple layers, the ultrasonic wave can be absorbed by the fabric as much as possible, and the energy utilization rate is high. Compared with the traditional cloth threading method, it can save energy by about 70%, significantly improving the cleaning effect of the water washing device, and is particularly suitable for fabrics that are relatively resistant to friction and need to imitate hand washing.

A roller-shaped support member 3 for guiding and supporting the fabric 100 is arranged between the cloth guide roller group 211 and the rear cloth guide roller group 221. The fabric 100 is reciprocated back and forth around the support member 3 between the front cloth guide rollers 211 and the rear cloth guide rollers 221 and then discharged. A vibrator installation chamber 5 is arranged on the front side of the fabric 100 on the support member 3 in the washing tank 1, and an ultrasonic vibrator assembly 6 is installed in the vibrator installation chamber 5.

[0023] Compared with the plate-shaped support member in Example 1, the roller-shaped support member in Example 2 has a curved contact surface between the fabric and the roller-shaped support member at the same width, and the contact surface between the fabric and the plate-shaped support member is at both ends of the support member. The contact surface between the roller-shaped support member and the fabric is larger, the effective impact force of the ultrasonic wave on the fabric is greater, and the cleaning effect is better.
