[Brief explanation of the drawings]

[0014] [Figure 1]1 is a schematic diagram of a small washing machine according to the present invention; [Figure 2] 1 is a cross-sectional view of a small washing machine according to the present invention; [Figure 3] 1 is a schematic diagram of the bottom structure of the washing machine of the present invention; [Figure 4] 1 is a schematic diagram of the pumping and draining structure of a small washing machine according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0015] We will now further describe specific embodiments of the present invention in combination with the drawings. The description of these embodiments is intended to aid in understanding the present invention, but is not intended to limit the present invention.

[0016] As shown in Figure 1-4, the small washing machine comprises washing tub 1, a wave-generating rotating member located inside washing tub 1, drive motor 4, control system, storage battery 7, and lower base body 13, and the output shaft of the drive motor is connected to wave-generating rotating member 5 to rotate the wave-generating rotating member inside the washing tub. The small washing machine further comprises water tub 2, pumping pump 8, drain pump 9, and pumping and drainage pipe 6, and the pumping pump communicates with the water tub and washing tub via the pumping and drainage pipe, and the drain pump communicates with the washing tub and drain outlet via the pumping and drainage pipe.

[0017] A tank seat is provided on the lower base body, a water stop valve seat is provided on the tank seat, a water stop valve 21 is attached to the bottom of the tank, a push-up rod is provided on one end of the water stop valve seat to push up the water stop valve, and the other end is connected to a pumping and drainage pipeline.

[0018] The inside of the washing tub 1 is provided with a ribbed wall that protrudes inward, and a control button 3 controls the start and stop of the small washing machine.

[0019] The pumping and drainage pipeline has a three-way pipe, which is composed of a first branch pipe 61, a second branch pipe 62 and a third branch pipe 63, the first branch pipe leading to the washing tub, the second branch pipe leading to the pumping pump, and the third branch pipe leading to the drainage pump.

[0020] A bottom drain seat 130 is provided on the lower base body, and the bottom drain seat has an open cavity that bulges upward. A first water pipe 131 passes through the open cavity, and the first water pipe 131 communicates with the hose 14 and the drain pump 9 respectively.

[0021] The edge of the bottom drain seat approaching the lower base is provided with a notch 134 for passing a pipe.

[0022] The bottom surface of the lower base is provided with a groove for accommodating hose 14. Before the washing machine is started, the hose is removed from the groove and one end of the hose is inserted into the outer side 132 of the first water pipe 131 of the washing machine, and the other end is extended from the pipe passage notch 134, allowing water to be drained out of the washing machine. After washing is finished, the hose is removed and stored in the groove.

[0023] The inside of washing tub 1 is provided with a ribbed wall 12 that protrudes inward. Control button 3 controls the start and stop of the small washing machine. Washing tub 1 is fixed to the base, and water tub 2 is placed on the tub seat of the base. A stop valve seat is provided in the center of the tub seat, the bottom of which connects to pumping and draining pipe 6, and a stop valve is attached to the bottom of the water tub. When the water tub is properly placed on the tub seat, the stop valve's push-up rod pushes up the stop valve, opening it, allowing clean water to pass through the stop valve and enter pumping and draining pipe 6. Pumping and draining pipe 6 has a three-way pipe consisting of first branch pipe 61, second branch pipe 62, and third branch pipe 63. First branch pipe 61 leads to washing tub 1, second branch pipe 62 leads to pumping pump 8, and third branch pipe 63 leads to draining pump 9, which control the flow of water between pumping pump 8 and draining pump 9. Water lift pump 8 serves to supply water from water tub 2 to washing tub 1. The flow path is water tub 2 → water pipe → water lift pump 8 → second branch pipe 62 → first branch pipe 61 → washing tub 1. Water drain pump 9 serves to discharge wastewater remaining in washing tub 1 after washing into an external water main via hose 14 at the bottom. The flow path is washing tub 1 → first branch pipe 61 → third branch pipe 63 → drain pump 9 → pump outlet 91 → water pipe (not shown) → bottom drain seat 130 → hose 14. The wastewater is discharged via hose 14.

[0024] The working process of this invention: The water tub can store and supply the clean water needed for washing. The washing mechanism mainly consists of a drive motor installed at the bottom of the washing tub and a ribbed rotating member connected to the drive motor's output shaft. During operation, the ribs on the surface of the ribbed rotating member and the obvious vortexes generated on the ribbed wall of the washing tub cause the clothes to roll and collide, washing them in all directions.

[0025] This washing machine has a washing tub located on the left and a water tub located on the right, and the water tub is portable. To use it, clothes are placed in the washing tub, fresh water is poured in, and the water tub is simultaneously filled to the MAX position. The power is turned on and operation begins. After the water from the water tub is poured into the washing tub and the washing machine is washed for three minutes, the wastewater is discharged outside via the drain pump. After detecting the drain pump's dry running using an electric current, the drain pump is stopped and the pumping pump is started. At the same time, the pumping time is detected and water is pumped into the washing tub to approximately half its capacity. After pumping for, for example, two minutes, the second wash begins. It is possible to set up three wash cycles.

[0026] In the water tank of a small washing machine, a water stop valve is movably installed on the lower base body, and a drain pump and a positive water pump are provided to control the flow of water in and out, and connecting pipes are provided to the drain pump and the positive water pump, and the water from the drain pump can be discharged outside the washing machine through a hose hidden at the bottom.
