[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1 to 4 The washing machine shown includes a pulsator type for underwear, comprising a casing 1 and a control system 2. The casing 1 contains a water tank 3, and the water tank 3 contains a washing tub 4. The casing 1 has an inlet 11 for placing clothes into the washing tub 4 and a cover 12 for closing the inlet 11. A pulsator 5 is located at the bottom of the washing tub 4. A drive mechanism 6 for rotating the pulsator 5 is located inside the casing 1. Several brush plates 7 with bristles are connected to the inner wall of the washing tub 4. The upper part of the washing tub 4 has an inwardly protruding ring 41, and the lower part of the ring 41 has a slot 411. The upper part of each brush plate 7 has a plug 71 that can be inserted into the slot 411, and the lower part of each brush plate 7 has an inwardly extending mounting foot 72. The mounting foot 72 has a mounting hole 721 open on one side. The washing tub 4 also has a connecting structure 8 that cooperates with the mounting hole 721 to fix the brush plate 7.

[0025] This invention provides additional physical friction during washing by installing a brush plate 7 with bristles on the inner wall of the washing tub 4, which helps to remove stains more effectively, especially stubborn stains on underwear or hard-to-reach areas. The brush plate 7 is inserted into the slot 411 via an upper insert 71, allowing the brush plate 7 to be easily inserted and locked in place. The lower part has an open mounting hole 721, which facilitates the fixing of the brush plate 7 by the connection structure 8 and the mounting hole 721, thereby improving assembly efficiency.

[0026] In one embodiment, the cross-section of the inner wall of the slot 411 is arc-shaped, and the inner side of the insert 71 is provided with an arc-shaped surface 711 that matches the inner wall of the slot 411. The arc-shaped design gives the insert 71 a certain self-guiding ability when inserted into the slot 411. Even if it is not perfectly aligned with the slot 411, the insert 71 can slide along the arc surface to the correct position, ensuring a smooth installation process. The tighter fit between the arc surfaces can effectively reduce installation errors caused by manufacturing tolerances or assembly inaccuracies, improving the consistency and accuracy of the brush plate 7 installation. The arc-shaped contact surface can provide a more uniform pressure distribution between the insert 71 and the slot 411, avoiding local stress concentration that may be caused by sharp corners or straight contact, thereby enhancing the stability and durability of the connection.

[0027] In one embodiment, the connecting structure 8 may be a threaded fastener such as a bolt or screw that is threadedly connected to the washing tub 4.

[0028] In one embodiment, the washing tub 4 is provided with a water inlet channel 42 that allows water from the water tank 3 to flow into the washing tub 4. A water channel 73 is provided on the back of the brush plate 7, and the brush plate 7 is provided with water outlets 74 that allow water from the water channel 73 to flow into the inner side of the brush plate 7, thus facilitating water intake. The pulsator-type underwear washing machine is also provided with a water inlet pipe that can connect to an external tap water pipe to supply water to the water tank 3, and a drain channel that can drain water from the water tank 3. Both the water inlet pipe and the drain channel are equipped with on / off valves for control.

[0029] In one embodiment, the drive mechanism 6 includes a rotating shaft 61 mounted on the water tank 3 and extending into the washing tub 4 and fixedly connected to the impeller 5, a motor fixedly connected to the housing 1, and a transmission assembly located between the motor output shaft and the rotating shaft 61. The transmission assembly may be a belt pulley drive group 610, a gear drive group, or a sprocket drive group.

[0030] Furthermore, a clutch 62 is provided between the rotating shaft 61 and the washing tub 4, enabling the washing tub 4 to rotate with the rotating shaft 61. The clutch 62 is a conventional clutch structure used in traditional pulsator washing machines to control the rotation of the washing tub 4 following the pulsator 5, and will not be described in detail here. The clutch 62 can be the clutch component described in patent publication number CN209397386U.

[0031] In one embodiment, the water tank 3 is suspended from the upper part of the inner cavity of the casing 1 by ropes 9. One end of each rope 9 is connected to the inner top of the casing 1, and the other end is connected to the outer wall of the water tank 3. There are three or more ropes 9, evenly distributed circumferentially on the outer side of the water tank 3. The even distribution of multiple ropes 9 provides multi-point support, ensuring that the water tank 3 remains stable under various operating conditions, reducing swaying and displacement. The suspension design can effectively absorb and disperse the vibrations generated during the operation of the washing machine, especially under the rotation of the impeller and the impact of water flow, preventing collisions between the water tank and the casing and reducing noise.

[0032] In one embodiment, both the water tank 3 and the washing tub 4 are cylindrical, allowing for a more even distribution of water flow within the tub. This avoids problems with poor water flow at corners or edges, helping to ensure that all clothes are thoroughly soaked and cleaned. The circular tub walls reduce water turbulence within the tub, resulting in a smoother flow and improved cleaning efficiency. This provides an ideal rotational environment for the impeller 5, enabling it to more effectively generate the necessary mechanical force and enhance the cleaning effect on clothes. It also facilitates the centrifugal spin-drying of the washing tub 4 after washing.
