[0002] Washing machines are now widely used in people's lives as household appliances. However, most washing machines on the market cannot clean localized stains on clothes separately. If clothes are stained in one area, the entire garment needs to be washed, and frequent washing can damage clothes, especially delicate fabrics. Summary of the Invention
[0003] The purpose of this invention is to provide a localized laundry device that can clean specific stains on clothing individually.
[0004] This invention is achieved through the following technical solution: a partial washing device, comprising an upper shell and a lower shell; A water tank is installed on the lower shell, and a washboard is installed in the water tank; the water tank is connected to a water supply device, and the water tank is also connected to a drain pipe; The upper shell is fitted with a cylindrical body with an open lower end, and the lower end of the cylindrical body is fastened to the water tank; a vertical output shaft is installed in the cylindrical body; the upper end of the vertical output shaft is connected to a power device for driving the vertical output shaft to rotate, and the lower end of the vertical output shaft is connected to a cleaning brush that cooperates with the washboard in the water tank. The cylinder has ventilation holes and is connected to a blower.
[0005] Furthermore, the water supply device is installed in the lower housing and includes a water storage tank; the water inlet of the water storage tank is connected to an inlet pipe, and the water outlet of the water storage tank is connected to a detergent dispensing box via a pipe; the detergent dispensing box is connected to the water tank via a pipe; and electromagnetic water valves are installed in both the pipe and the drain pipe.
[0006] The power unit is installed in the upper housing. The power unit includes a ring-shaped fifth internal gear, and a second transmission shaft is provided on the shaft of the fifth internal gear. A support plate is fixed to the lower end of the second transmission shaft. The upper end of the vertical output shaft is rotatably mounted on the support plate through a bearing. A third gear that meshes with the fifth internal gear is also fixed to the upper end of the vertical output shaft.
[0007] The power unit also includes a first transmission shaft parallel to the second transmission shaft, and a motor; a first bevel gear is fixedly mounted on the output shaft of the motor; a second bevel gear and a first gear are fixedly mounted on the first transmission shaft, and the second bevel gear meshes with the first bevel gear; a second gear is fixedly mounted on the second transmission shaft, and the second gear meshes with the first gear.
[0008] A pair of slide rods parallel to the vertical output shaft are fixed on the support plate; The cleaning brush includes a fine-bristle brush disc and a coarse-bristle brush disc slidably mounted on the lower end of the slide rod, with the coarse-bristle brush disc located above the fine-bristle brush disc; the lower end of the vertical output shaft has a bidirectional threaded screw; the upper and lower sections of the bidirectional threaded screw have opposite thread directions, and the upper and lower sections of the bidirectional threaded screw are correspondingly connected to the fine-bristle brush disc and the coarse-bristle brush disc. A fine brush is fixed to the lower side of the fine brush plate, and a coarse brush is fixed to the lower side of the coarse brush plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are: Controlling the motor to rotate forward and reverse can switch the rotation direction of the vertical output shaft. During the movement, the two brush discs move closer to each other, the fine brush bristles retract and the coarse brush bristles extend; conversely, the coarse brush disc moves upward and the fine brush disc moves downward, the fine brush bristles extend and the coarse brush bristles retract; the whole process generates alternating rubbing force on the clothes, improving the cleaning effect. The washing station is equipped with a washboard surface to increase friction during the washing process and improve cleaning efficiency. The water tank and drum are well sealed to prevent water leakage during the washing process. The blower blows air into the inner drum through the air duct and comes into contact with the clothes. The generated hot steam is quickly discharged through the air vents on the inner drum, thus drying the clothes so they can be worn soon after washing. This invention can clean local stains on clothing separately, washing and drying immediately, which is more convenient, saves time and effort, and can also reduce the damage to clothing caused by machine washing to a certain extent.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Combination Figures 1 to 3 As shown, a partial washing device comprises an upper housing 3 and a lower housing 4. A water tank 24 is mounted on the lower housing 4, and a washboard 25 is installed within the water tank 24. A drum 5 with an open lower end is mounted on the upper housing 3, and the lower end of the drum 5 is fastened to the water tank 24. A power unit, a cleaning brush, and a blower are installed in the upper housing 3. A water supply device is installed in the lower housing 4.
[0023] Combined Figure 4As shown, the power unit drives the vertical output shaft 19 to rotate and revolve. The power unit includes a ring-shaped fifth internal gear 20, with a second transmission shaft 17 mounted on its axis. A support plate 35 is fixed to the lower end of the second transmission shaft 17, and a second gear 16 is fixedly mounted on it. The upper end of the vertical output shaft 19 is rotatably mounted on the support plate 35 via bearings, and a third gear 18, meshing with the fifth internal gear 20, is also fixed to the upper end of the vertical output shaft 19. The first transmission shaft 14 is parallel to the second transmission shaft 17. A first bevel gear 12 is fixedly mounted on the output shaft of the motor 11. A second bevel gear 13 and a first gear 15 are fixedly mounted on the first transmission shaft 14; the second bevel gear 13 meshes with the first bevel gear 12, and the first gear 15 meshes with the second gear 16.
[0024] The transmission process is as follows: Motor 11 drives the first bevel gear 12 to rotate, the rotation of the first bevel gear 12 drives the second bevel gear 13 to rotate, and then the second bevel gear 13 drives the first transmission shaft 14 to rotate. The rotation of the first transmission shaft 14 drives the first gear 15 to rotate, the rotation of the first gear 15 drives the second gear 16 to rotate, and then the second gear 16 causes the second transmission shaft 17 to rotate. The rotation of the second transmission shaft 17 causes the third gear 18 to revolve around the fifth internal gear 20, while simultaneously rotating on its own axis. The rotation of the third gear 18, while rotating, drives the vertical output shaft 19 to rotate.
[0025] Combination Figure 4 and Figure 5 As shown, a pair of slide rods 23 parallel to the vertical output shaft 19 are fixed on the support plate 35. The cleaning brush includes a fine brush disc 22 and a coarse brush disc 21 slidably mounted on the lower end of the slide rods 23, with the coarse brush disc 21 located above the fine brush disc 22. The lower end of the vertical output shaft 19 has a bidirectional threaded screw 34; the upper and lower sections of the bidirectional threaded screw 34 have opposite thread directions, and the upper and lower sections of the bidirectional threaded screw 34 are correspondingly connected to the fine brush disc 22 and the coarse brush disc 21. A fine brush is fixed to the lower side of the fine brush disc 22, and a coarse brush is fixed to the lower side of the coarse brush disc 21. The fine brush disc 22 has holes for the coarse brush to pass through.
[0026] When the motor starts, the bidirectional threaded screw 34 rotates forward or backward. Driven by the rotation of the bidirectional threaded screw 34, the fine brush disc 22 and the coarse brush disc 21 revolve and move closer or further apart, respectively. The fine and coarse brushes under the fine brush disc 22 and the coarse brush disc 21 apply varying pressure to the clothing. The forward and reverse rotation times of the motor need to be set in advance. Before the fine brush disc 22 and the coarse brush disc 21 reach their extreme positions of approaching or separating, the motor needs to reverse direction.
[0027] Combination Figure 3 and Figure 6As shown, the blowing device is installed in the upper housing 3. The blowing device includes a blower 8, and the air outlet of the blower 8 is connected to the cylinder 5 through a ventilation duct 9. A heating pipe 10 is installed in the ventilation duct 9. The cylinder 5 is provided with a ventilation hole 6.
[0028] Blower 8 draws in cold air from the outside, which enters the inner drum 5 through ventilation duct 9. A heating element 10 is built into ventilation duct 9, which turns the cold air into dry hot air, which is then blown into the inner drum through ventilation duct 9 to contact the clothes. The inner drum 5 is equipped with vents 6. The hot steam generated after the hot air comes into contact with the moisture on the clothes is quickly discharged from the inner drum through the vents 6, preventing moisture from accumulating inside the drum, thereby achieving the purpose of drying clothes.
[0029] Combination Figure 3 and Figure 7 As shown, the water supply device is installed in the lower housing 4, and includes a water storage tank 27. The water inlet of the water storage tank 27 is connected to an inlet pipe 29, and the water outlet of the water storage tank 27 is connected to a detergent dispenser 26 via a pipe. The detergent dispenser 26 is connected to a water tank 24 via a pipe, and the water tank 24 is connected to a drain pipe 33. Electromagnetic water valves 28 are installed in both the pipes and the drain pipe 33. A sealing gasket 7 is fixed to the edge of the water tank 24, and the sealing gasket 7 mates with the lower end of the cylinder 5 to ensure that water does not leak out during the cleaning process.
[0030] During use, water enters through the inlet, and the inlet and outlet are automatically controlled by an electromagnetic water valve. The water flows through the water pipe to the detergent dispenser 26, where it mixes with the pre-added detergent. The detergent-mixed water is then sent to the sink 24 through the water pipe. When the water level is higher than the plane of the washboard 25, the water flows through the holes in the washboard 5 into the inner drum 5 to wet the clothes. The wastewater after washing is discharged from the drain pipe 33 through the drain pipe.
[0031] Combination Figure 1 As shown, a cover plate 1 is fixed to the upper end of the upper housing 3, and a base plate 2 is fixed to the lower end of the lower housing 4. A lifting mechanism 32 is fixed to the end of the upper housing 3 away from the cylinder 5, and the lifting mechanism 32 is hinged to the lower housing 4. A lifting button 31 is installed on the lower housing 4 to position the lifting mechanism 32 to the lower housing 4. A control knob 30 is used to control the power unit, the air blowing device, and the water supply device.
[0032] The upper housing 3 and the lower housing 4 are connected by a lifting mechanism 32. In use, first press the lifting button to lift the upper housing 3, lay the stained area of the garment flat on the washboard 25, then press the lifting button again to press the upper body back down. At this time, the cleaning brush inside the inner drum 5 can touch the surface of the garment for cleaning.
[0033] In this embodiment, controlling the motor's forward and reverse rotation switches the rotation direction of the vertical output shaft. During movement, the two brush discs move closer together, with the finer bristles retracting and the coarser bristles extending; conversely, the coarser brush disc moves upward while the finer brush disc moves downward, with the finer bristles extending and the coarser bristles retracting. This process generates alternating rubbing forces on the clothes. The blower blows air into the inner drum through the air duct, contacting the clothes. The generated hot steam is quickly discharged through the vents on the inner drum, thus drying the clothes, allowing them to be worn quickly after washing. This invention allows for targeted cleaning of localized stains on clothing, enabling immediate washing and drying, which is more convenient, saves time and effort, and reduces damage to clothing caused by machine washing of the entire garment.
