[0002] At present, most of the drum or impeller washing machines on the market are used to wash daily clothes. In actual use, they are rarely used to wash underpants. On the one hand, the ordinary washing machine drum contains many bacteria, and it is not sanitary to wash underpants. On the other hand, the capacity of underpants is small, and it is a waste of water and electricity to use a large washing machine to wash a few underpants. Therefore, in daily life, underwear is usually washed by hand, which is time-consuming and laborious.

[0003] Therefore, small impeller or drum washing machines specially used for washing underpants appear on the market. For example, the washing machine with patent number ZL202110470713.4 adopts a special mechanical structure to simulate manual washing action to realize the washing of underpants and socks. However, the shape and structure of this washing machine are special, the washing space is small, it is not easy to wash clean, and it is limited by the space for placing the washing machine in the user's home, so the application range has many limitations.

[0004] In addition, small impeller and drum washing machines have been designed for the special washing of underwear.

[0051] The complete operation process of the washing device of the embodiment is as follows:

[0052] ①Open the upper cover 11, put the clothes (such as underwear) to be washed into the washing barrel 4, and add detergent.

[0053] ②The water inlet valve is opened, the water pump 6 is started, after reaching the preset time t, the water inlet valve is closed, and the water pump 6 is always running to ensure that the jet flow of the spraying device always occurs.

[0054] ③The motor 81 starts to work, the rotating and pressing device acts, and the pressing plate 73 rotates and descends until it presses the clothes to be washed in the washing barrel 4;

[0055] At the same time, the current value of the motor 81 is detected in real time, and compared with the set pressing threshold and no-load threshold. When the real-time current value of the motor 81 reaches the pressing threshold, the pressing plate 73 stops descending and reverses to ascend. When the real-time current value of the motor 81 reaches the no-load threshold, the pressing plate 73 reverses and descends again. Repeat this process, through the pressing of the clothes to be washed by the pressing plate 73 and the friction between the convex ribs 731 at the bottom of the pressing plate 73 and the clothes to be washed, and combined with the jet flow of the spraying device, to realize the washing of the clothes, until the main washing program ends.

[0056] ④After the main washing program ends, open the drain valve 521, and the water pump 6 is still on until all the water in the water storage tank 13 is drained.

[0057] ⑤Execute the rinsing program, repeat steps ②, ③ and ④ above, until the rinsing is finished and the drainage is completed, and the washing process is finished.

[0058] The washing device of the embodiment is compact and small, can be used in different washing environments, and is easy to operate. By combining the jet washing and pressing friction, the washing of the clothes (such as underwear) is realized. Compared with the traditional pulsator and drum washing method, the washing rate is greatly improved. In addition, there is only one washing barrel 4, because there is no outer barrel, which can effectively avoid the accumulation of dirt and the breeding of bacteria, so that the washing barrel 4 is more easily disassembled and cleaned.
