The installation positions of the first spray head 4 and the second spray head 40 are not limited to the positions shown in the figure. For example, the first spray head 4 above and the second spray head 40 below can also be placed at a certain position staggered in the circumferential direction, but it is necessary to ensure that the spray coverage area of ​​the spray head is as large as possible, but it cannot affect the placement of clothes.

[0051] In one embodiment, the length of the first spray head 4 extending into the washing tub 3 does not exceed 1 / 2 of the diameter of the washing tub 3, and the first spray head 4 extends horizontally in a direction close to the center of the washing tub 3, ensuring that the clothes can be fully washed without affecting the placement of the clothes. The structural forms of the first spray head 4 and the second spray head 40 can be diversified, and can be retractable or foldable.

[0052] The placement plate 5 is provided with water-permeable holes 52, which not only allow the spray water of the second spray head 40 at the bottom to spray and wash the clothes smoothly from the bottom, but also facilitate the washing water and foam on the upper part of the placement plate 5 to flow to the bottom of the washing tub 3, avoiding the washing water from being retained on the placement plate 5. The washing water is led to the first spray head 4 again through the circulating water pipeline, thereby facilitating the recycling of the washing water and improving the recycling efficiency of the washing water. The water-permeable holes 52 can be parallelograms, circles, triangles, etc., or other regular or irregular shapes without limitation.

[0053] The placement plate 5 includes a circular plate 51 on which an arc-shaped groove 53 is arranged. The arc-shaped groove 53 is used as a mark for users to place clothes. It is simple and clear, and can facilitate shaping of underwear during the washing process to avoid deformation of the underwear.

[0054] In one embodiment, the number of arc-shaped grooves 53 is an even number, and the even number of arc-shaped grooves 53 are symmetrically arranged about the rotation axis of the placement plate 5, which can not only ensure the balance of the overall structure of the placement plate 5 during the rotation process, but also increase the number of arc-shaped grooves 53, so that multiple pieces of underwear can be placed and washed on the placement plate 5 at the same time, thereby improving the underwear washing efficiency.

[0055] The bottom of the placement plate 5 is provided with a support rib 54, which is located between two adjacent arc-shaped grooves 53 or directly at the bottom of the arc-shaped groove 53. The support rib 54 is arranged at the bottom of the circular plate 51 of the placement plate 5, and can support the circular plate 51, thereby supporting the placement plate 5 and increasing the structural strength. The four support ribs 54 are composed of two long support ribs and two short support ribs, all of which are plates with a certain thickness and a certain structure. In order to increase reliability, the support rib 54 is made into one piece with the placement plate 5. In addition, the upper end surface of the short support rib just contacts the bottom of the arc-shaped groove 53 of the placement plate, so its upper end surface is made into an arc shape that fits the bottom of the arc-shaped groove 53. The two long support ribs and the two short support ribs are arranged in a cross-symmetric manner to support the placement plate 5, and are connected to the rotating shaft 8 at the center of the cross-symmetry.
