[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Example 1

[0014] like Figure 1As shown, a cloth guide roller unit for a washing machine comprises two cloth guide roller groups arranged front and back in cloth feeding and cloth discharging directions, the cloth guide roller group close to the cloth feeding side is the front cloth guide roller group 10, and the cloth guide roller group close to the cloth discharging side is the rear cloth guide roller group 20, the front cloth guide roller group 10 comprises a plurality of front cloth guide rollers 101, the rear cloth guide roller group 20 comprises a plurality of rear cloth guide rollers 201, each of the front cloth guide rollers 101 and each of the rear cloth guide rollers 201 is horizontally distributed, the fabric 100 is reciprocated back and forth between each of the front cloth guide rollers 101 and each of the rear cloth guide rollers 201 before the fabric is discharged, and the horizontal positions of the horizontal low points A and B of the covering sections of the fabric 100 on two adjacent front cloth guide rollers 101 and the rear cloth guide rollers 201 are lower than the horizontal positions of the horizontal low points of the covering sections of the fabric 100 on the remaining front cloth guide rollers 101 and the rear cloth guide rollers 201. Example 2

[0015] like Figure 2 As shown, a washing machine comprises a washing tank 1, in which two cloth guide roller units 2 described in Example 1 are installed, and a transition roller 3 is installed between adjacent cloth guide roller units 2. After the fabric 100 is discharged from the cloth guide roller unit 2 at the front end, it bypasses the transition roller 3 and enters the cloth guide roller unit 2 adjacent to the cloth guide roller unit 2; in the washing tank 1, a vibrator mounting groove 4 is arranged at a close distance below the fabric 100 between two adjacent front cloth guide rollers 101 and the rear cloth guide roller 202 in each of the cloth guide roller units 2, and an ultrasonic vibrator assembly 5 is installed in the vibrator mounting groove 4.

[0016] During operation, the fabric is reciprocatedly wound between the front cloth guide roller and the rear cloth guide rollers in the cloth guide roller unit located at the front end and then discharged. After discharged, the fabric bypasses the transition roller 4 and enters the cloth guide roller unit 2 located at the rear end. The cloth guide roller unit stacks the single-layer fabric into multiple layers when the fabric is fed in. The support further reduces the spacing between the multiple layers of fabric between the front cloth guide roller group and the rear cloth guide roller group. The shock waves generated by the "cavitation effect" of ultrasonic waves in the liquid are absorbed by the fabric as much as possible, with high energy utilization rate. Compared with the traditional cloth threading method, it can save energy by about 70%, and significantly improve the cleaning effect of the water washing device.

[0017] The number and size of the front cloth guide roller and the rear cloth guide roller of the utility model are not limited, and they are designed according to specific working conditions, as long as the fabric can be wound back and forth between the front cloth guide rollers and the rear cloth guide rollers through the support member and then discharged. Usually, thin fabrics have more layers, such as five layers, and thick fabrics have three layers.

[0018] The horizontal position of the lowest point of the covering section of the fabric on the two adjacent front cloth guide rollers and the rear cloth guide roller is limited to the closeness of the layers of fabric between the front cloth guide roller and the rear cloth guide roller. When the horizontal position of the lowest point of the covering section of the fabric on the two adjacent front cloth guide rollers and the rear cloth guide roller is lower than the horizontal position of the lowest point of the covering section of the fabric on the remaining front cloth guide rollers and the rear cloth guide rollers, the layers of fabric between the adjacent front cloth guide rollers and the rear cloth guide rollers can be overlapped, and the ultrasonic washing effect is better.

[0019] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
