Description

Technical Field

[0001] This utility model relates to the field of washing device technology, and in particular to a small washing machine. Background Technology

[0002] Washing machines are common household appliances. They typically handle large loads and are bulky, making them unsuitable for carrying or transporting. With improved living standards and increased demands for laundry sorting, more and more families and frequent travelers are opting for smaller washing machines. For example, Chinese utility model application CN202320946228.4 discloses a small underwear washing machine, belonging to the field of small washing machine technology. It includes a main casing and a water supply mechanism, including a water storage tank inside the main casing to store and supply water for cleaning clothes; and a cleaning mechanism, including a drive motor located at the bottom of the main casing and a cleaning wheel connected to the output shaft of the drive motor. During operation, this utility model utilizes a spiral turbine design with large protrusions and ribs to generate rotating vortices when the cleaning wheel rotates. This not only tumbles the clothes, increasing the contact stress between the clothes and water, but also improves the overall cleaning effect regardless of the size of the clothes. However, this small washing machine has both a washing tub and a spin-drying basket, as well as different sterilization devices such as heating and ultraviolet lamps, making the product structure relatively complex and bulky, heavy, and costly, requiring further improvement.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] See Figures 1-4 As shown, this utility model discloses a small washing machine, including a washing tub 1 and an impeller inside it, a drive motor, a control system, and a base 13. The output shaft of the drive motor is connected to the impeller and drives the impeller to rotate inside the washing tub. The feature is that it also includes a water storage tank 2, a water pump 8, a drain pump 9, and a water pumping and draining pipe 6. The water pump is connected to the water storage tank and the washing tub through the water pumping and draining pipe, and the drain pump is connected to the washing tub and the drain outlet through the water pumping and draining pipe.

[0023] The base is equipped with a bucket seat, and the bucket seat is equipped with a water stop valve seat. The bottom of the water storage tank is equipped with a water stop valve. One end of the water stop valve seat is equipped with a pin for opening the water stop valve, and the other end is connected to the drainage pipe.

[0024] The inner side of the washing tub 1 is provided with inwardly protruding ribs, and the control button 3 controls the start and stop of the small washing machine.

[0025] The drainage pipeline includes a tee pipe, which includes a first branch pipe 61, a second branch pipe 62, and a third branch pipe 63. The first branch pipe is connected to the washing tub, the second branch pipe is connected to the water pump, and the third branch pipe is connected to the drain pump.

[0026] A base drain seat 130 is provided on the base. The base drain seat has an upward-bulging open mouth. A first water pipe passes through the open mouth and is connected to a hose 14 and a drain pump.

[0027] The base drain seat has a pipe passage notch 134 near the edge of the base.

[0028] The bottom surface of the base is provided with a slot for storing the hose 14.

[0029] The inner side of the washing tub 1 has inwardly protruding ribs, and the control button 3 controls the start and stop of the small washing machine. The washing tub 1 is fixed on the base, and the water storage tank 2 is placed on the tub seat of the base. A water stop valve seat is set in the center of the tub seat, and the bottom of the water stop valve seat is connected to the drain pipe 6. A water stop valve is installed at the bottom of the water storage tank. When the water storage tank is correctly placed on the tub seat, the pin of the water stop valve seat presses against the water stop valve to open the valve, and the cleaning water can enter the drain pipe through the water stop valve. The drain pipe 6 is equipped with a three-way pipe, which consists of a first branch pipe 61, a second branch pipe 62, and a third branch pipe 63. The first branch pipe 61 is connected to the washing tub 1, the second branch pipe 62 is connected to the water pump 8, and the third branch pipe 63 is connected to the drain pump 9. The flow is controlled by the water pump 8 and the drain pump 9. The water pump 8 is responsible for supplying water from the water storage tank 2 to the washing tub 1. The flow direction is: water storage tank 2 -- water pipe -- water pump 8 -- second branch pipe 62 -- first branch pipe 61 -- washing tub 1. The drain pump 9 is responsible for draining the wastewater from the washing tub 1 after washing to the external water channel through the bottom hose 14. The flow direction is: washing tub 1 -- first branch pipe 61 -- third branch pipe 63 -- drain pump 9 -- pump outlet 91 -- water pipe -- base drain seat 130 -- hose 14. The wastewater is discharged through the hose 14.

[0030] The working process of this invention: The water storage tank can store and provide the cleaning water needed for washing. The cleaning mechanism mainly includes a drive motor located at the bottom of the washing tub and a washing impeller connected to the output shaft of the drive motor. During operation, the vortex generated by the ribs and protrusions on the surface of the washing impeller can tumble and collide with the clothes, achieving all-round cleaning.

[0031] This washing machine consists of two parts: a washing tub on the left and a water tank on the right. To use, place clothes in the washing tub and pour in clean water. Simultaneously, fill the water tank (which is liftable). Turn on the machine and run for approximately three minutes. The wastewater from the washing tub will be pumped out of the main unit by the drain pump. After the water pump stops empty (based on current detection), it shuts off and the intake pump turns on, pumping half the water from the storage tank into the washing tub (time detection, approximately 2 minutes). The second wash cycle begins. After three minutes, the drain pump turns on again, draining the remaining water from the storage tank into the washing tub (based on current detection). Then, the final wash cycle begins. After the final wash cycle, the drain pump resumes draining, completing the entire washing process. Remove the clothes, wring them out, and hang them to dry.

[0032] The water storage tank is mounted on the base using a movable sleeve with a stop valve. Two water pumps, one for drainage and one for water supply, control the inlet and outlet of the water. The inlet and outlet pumps are connected by pipes, and the water from the drain pump can be discharged to the outside of the washing machine through a hose hidden at the bottom.

[0033] The machine has a simple structure, optimized parts, low cost, and practical functions. It reduces unnecessary functions such as disinfection and water spraying, and is characterized by its simplicity and practicality.

[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
