[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0024] like Figures 1 to 3 As shown, a guide roller includes a roller body 1. Several rows of amplitude adjustment units 2 are arranged parallel to each other at equal intervals along the circumference of the outer wall 11 of the roller body 1. Each amplitude adjustment unit 2 includes a first convex ridge segment 21 and a second convex ridge segment 22. Both the first convex ridge segment 21 and the second convex ridge segment 22 are oblique lines. When the roller body 1 is unfolded into a plane, the first convex ridge segment 21 and the second convex ridge segment 22 are mirror-symmetrical about the outer wall line of the roller circumference corresponding to the axial center of the roller body 1. A third convex ridge segment 23 connects the first convex ridge segment 21 and the second convex ridge segment 22, and the third convex ridge segment 23 is parallel to the axial direction of the roller body 1.

[0025] In this embodiment, as Figure 3 The amplitude adjustment unit 2 shown is arranged around the circumference of the roller body 1 to form a roller body with a wave pattern. Compared with the pattern of the traditional straight-line convex wave roller, the wave pattern has the following advantages: In the washing machine, when the fabric passes through the guide roller and the guide roller rotates in an expanded direction, the first convex section and the second convex section form an angle difference with the axial direction of the guide roller, which can peel the fabric to both sides, making the fabric surface flat, effectively reducing wrinkles and improving the washing quality. Example 2

[0026] like Figure 4 and Figure 5 As shown, the difference between Embodiment 2 and Embodiment 1 is that the guide roller does not have a third convex ridge section, and the ends of the first convex ridge section 21 and the second convex ridge section 22 are connected. This structure has the best expansion effect. Example 3

[0027] like Figure 6As shown, a water washing machine, which comprises an upper fabric guide roller set 20 and a lower fabric guide roller set 30 installed in a water washing tank 10, the upper fabric guide roller set 20 comprises a plurality of upper fabric guide rollers 201, the lower fabric guide roller set 30 comprises a plurality of lower fabric guide rollers 301, the axes of the upper fabric guide rollers 201 and the lower fabric guide rollers 301 are parallel to each other, the upper fabric guide rollers 201 and the lower fabric guide rollers 301 are passive rollers, a fabric 100 is wound between each of the lower fabric guide rollers 301 and each of the upper fabric guide rollers 201 in a serpentine shape along the running direction of the fabric, the structure of the upper fabric guide rollers 201 is the structure of the guide roller described in Embodiment 1, the turning direction of the upper fabric guide rollers is limited to the effect that the fabric is peeled off from both sides in the width direction when the fabric 100 passes through the upper fabric guide rollers, and the upper fabric guide rollers rotate clockwise in this embodiment.

[0028] The end portions of the first ridge segments and the second ridge segments can not be connected, and the first ridge segments and the second ridge segments of the same size in each amplitude modulation unit can ensure the accurate expansion of the fabric during the running process.

[0029] The third ridge segments are arranged according to needs, and the relative end portions of the first ridge segments and the second ridge segments can not be connected, which can improve the strength of the roller body and improve the washing effect.

[0030] The first ridge segments and the second ridge segments are not limited to oblique lines, and can also be arc-shaped spiral segments extending to the end portions of the roller body, and the size of the spiral segments is limited to the effect that the fabric is peeled off from both sides in the width direction when the fabric passes through the guide roller.

[0031] The application of the guide roller is not limited to the embodiment, and when the turning direction of the guide roller is opposite to that of Embodiment 2, the two sides of the fabric are contracted in the middle in the width direction, which plays a role of reducing the amplitude.

[0032] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent process transformation or direct or indirect application in other related technical fields according to the content of the utility model specification is also included in the patent protection range of the utility model.
