A compact undergarment washing machine

Abstract

This invention provides a small underwear washing machine, belonging to the technical field of small washing machines. It includes a main housing and a water supply mechanism, comprising a water tank located inside the main housing for storing and supplying water for cleaning clothes; and a cleaning mechanism, including a drive motor located at the bottom of the main housing and a cleaning wheel connected to the output shaft of the drive motor. During operation, the invention utilizes a spiral turbine-like design with large protrusions and ribs to generate rotating vortices when the cleaning wheel rotates. This not only drives the clothes to rotate and tumble, increasing the contact stress between the clothes and water, but also improves the overall cleaning effect regardless of the size of the clothes. Furthermore, the ribs provide flexible protection during washing, preventing clothes from twisting together and improving the cleaning effect. They also prevent excessive rotational resistance caused by clumped clothes, which could increase the resistance of the drive motor and burn out the internal coils.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments.

[0036] Example

[0037] Reference Figures 1-8 A small underwear washing machine includes a main housing 1, and further includes:

[0038] The water supply mechanism includes a water storage tank 25 disposed inside the main housing 1, which can store and provide water for cleaning clothes for the device;

[0039] The cleaning mechanism includes a drive motor 7 located at the bottom of the main housing 1 and a cleaning wheel 9 connected to the output shaft of the drive motor 7. When working, the vortex generated by the rotation of the ribs 901 and the large protrusions 904 on the surface of the cleaning wheel 9 can tumble and collide with the clothes, thus cleaning the clothes in all directions.

[0040] The disinfection mechanism includes a heating plate 16 and a UVC ultraviolet disinfection lamp 12 installed inside the main housing 1. During washing, different temperatures of water-heat disinfection or ultraviolet disinfection can be used to disinfect clothes according to different clothing materials and disinfection requirements.

[0041] Reference Figure 1 The main housing 1 houses a washing tub 3, which has multiple protrusions 302 on its inner wall. A bottom shell 4 provides support and sealing protection. A top cover 6, matching the opening at the top of the washing tub 3, is hinged to the top of the tub 3. An upper cover 2 is mounted on top of the upper cover 6, and a sealing ring 5 is placed between the upper cover 2 and the top cover 6 for sealing. A drive motor 7 is located directly below the washing tub 3 inside the main housing 1. A motor shaft sealing ring 26 is placed between the output shaft of the drive motor 7 and the washing tub 3. A UVC ultraviolet disinfection lamp 12 is also installed inside the main housing 1. A notch is provided on one side of the top of the washing tub 3, and a [further details about the notch are missing]. A limiting slot 303 is provided, and a cover opening button assembly 305 is provided at the limiting slot 303. The cover opening button assembly 305 and the edge of the upper cover 2 adopt a matching snap-on design. A power supply and control board 701 is fixedly installed inside the main housing 1, facing the side wall of the washing tub 3. An infrared emitting sensor 703 and an infrared receiving sensor 704 are fixedly installed on the side wall of the power supply and control board 701. The power supply and control board 701 is also connected to a power cord 702 extending to the outside of the device. A knob display screen 15 is provided on the top of the main housing 1. A drain solenoid valve 802 is provided at the bottom of the washing tub 3. The input end of the drain solenoid valve 802 is connected to the drain outlet of the washing tub 3, and the output end of the drain solenoid valve 802 is connected to the external drain pipe.

[0042] The disinfection mechanism includes a heating plate 16, which is located at the center of the bottom of the inner cavity of the washing tub 3. A heating plate sealing ring 20 is provided between the edge of the heating plate 16 and the washing tub 3 for sealing. A temperature sensor 161 is provided on the top of the heating plate 16. A set of rotating shafts connected to the output shaft of the drive motor 7 are rotatably connected to the center of the heating plate 16 through a bearing seal. The cleaning mechanism includes a cleaning wheel 9, which is limited and sleeved on the outside of the rotating shaft. A motor shaft waterproof sealing ring 21 is also provided between the rotating shaft and the cleaning wheel 9 for sealing. A bushing 903 is provided on the top of the cleaning wheel 9.

[0043] Furthermore, the cleaning wheel 9 has a design that is large at the bottom and small at the top, and the waistline of the cleaning wheel 9 has a streamlined design. The bottom of the cleaning wheel 9 has a through hole 902, and the side wall of the cleaning wheel 9 has a large arc-shaped protrusion 904 with a spiral twist. The top of the large protrusion 904 is fixedly installed with a rib 901, which is made of fluorosilicone butyl rubber material that is resistant to high temperature, waterproof, impact, and corrosion.

[0044] It should be noted that the vortex generated by the directional rotation of the large raised platform 904 and the flexible raised ribs 901 driven by the first motor 7 can quickly rotate and tumble the clothes. When the clothes rotate and hit the large raised platform on the washing tub 3 and the top cover 6, the clothes will continuously tumble and hit these raised platforms, which will have a washing effect of slapping and impacting until the stains on all parts of the clothes are cleaned.

[0045] Furthermore, the water supply mechanism includes a water storage tank 25, which is movably fitted inside the main housing 1. A set of inlet solenoid valves 801 with their output ends connected to the inner cavity of the water storage tank 25 is fixedly installed inside the main housing 1. A one-way valve 27 is also provided at the bottom of the water storage tank 25. A water tank support 23 is provided inside the water storage tank 25. A water tank cover 24 is provided at the top of the water storage tank 25. A water tank handle 22 is provided at the top of the water storage tank 25. A magnetic induction switch 13 is provided inside the main housing 1. A magnetic levitation device 14 is provided inside the water storage tank 25. A water pump 11 is provided inside the main housing 1. A water inlet 101 is provided at the bottom of the water storage tank 25. A connecting pipe 10 connects the water inlet 101 and the water pump 11. A flow sensor 8 is connected to the output end of the water pump 11. The output end of the flow sensor 8 is connected to the outlet 102.

[0046] Furthermore, the maglev 14 is connected to the water tank 25 in a limited sliding sleeve via a set of vertical slide rails;

[0047] It should be noted that, through the vertical limiting sliding connection, the magnetic levitation 14 can rise vertically along the slide rail as the water volume increases, driven by the buoyancy of the water. When the magnetic levitation 14 rises to the position corresponding to the magnetic induction switch 13, the water volume inside the water tank 25 reaches the set height of the magnetic induction switch 13. The magnetic force of the permanent magnet inside the magnetic levitation 14 can cause the magnetic induction switch 13 to be attracted and quickly close short-circuit. At the same time, a signal is sent through the circuit to the central control unit to inform that the water tank 25 is full. At this time, the central control unit sends a stop water filling command to the circuit, de-energizes the water inlet solenoid valve 801 to stop water filling, and feeds back to the central control unit to proceed to the next working step.

[0048] Furthermore, a ring-shaped water spray device 18 is fixedly installed inside the top cover 6. The water spray device 18 is connected to the water outlet 102 through a set of vertically designed straight pipes. At the bottom of the water spray device 18, there are also multiple sets of spray heads 181 extending to the outside of the top cover 6.

[0049] It should be noted that a set of T-shaped tee pipes is provided at the connection part between the water spray device 18 and the straight pipe, and the tee pipes are rotatably connected to the connection part of the water spray device 18, and the connection part is waterproof and sealed.

[0050] Specifically, through the rotating connection design, when the top cover 6 is rotated open to take out or put in clothes, the water spray device 18 can maintain synchronous rotation through the sealed rotating connection between the T-shaped three-way pipes.

[0051] Furthermore, a torsion spring 17 is provided at the connection between the washing tub 3 and the top cover 2, and a set of pins 19 is provided at the center of the torsion spring 17 for hinged connection of the torsion spring 17, the washing tub 3 and the top cover 2.

[0052] Reference Figure 1 The rotary display screen 15 is electrically connected to the power supply and control board 701 via a set of connecting cables. The drive motor 7, flow sensor 8, water pump 11, magnetic induction switch 13, water inlet solenoid valve 801, and drain solenoid valve 802 are all electrically connected to the power supply and control board 701.

[0053] The working principle of this small underwear washing machine:

[0054] First, rotate the top cover 2. Place the clothes and detergent inside the washing tub 3, then close the top cover 2. Turn on the machine by rotating the knob on the display screen 15, select the washing mode, and confirm. The system, sensing that the top cover 2 is closed via the infrared transmitter sensor 703 and the infrared receiver sensor 704, begins operation. First, water is added to the water tank 25 via the water supply system. The central processing unit opens the inlet solenoid valve 801, allowing tap water to flow into the water tank 25 through the inlet solenoid valve 801 and the one-way valve 27. The magnetic levitation system 14 inside the water tank 25 then... When the water level rises, the buoyancy can drive the magnetic levitation 14 to rise until it reaches the position set by the magnetic induction switch 13, that is, when the water volume for one cleaning is reached, the magnetic levitation 14 in the water storage tank 25 floats to the rated water level line due to the buoyancy of the water, which will trigger the magnetic induction switch 13 inside the machine to indicate that the system is full of water. The magnetic induction switch 13 circuit is connected to the central processing unit. After the central processing unit receives the magnetic induction switch 13 being turned on, it sends a power-off command to the water inlet solenoid valve 801 to stop adding water. The water inlet solenoid valve 801 is de-energized, and the faucet stops adding water to the water storage tank 25.

[0055] Furthermore, the cleaning system is controlled by the power supply and control board 701 to initiate the cleaning process. First, the central processing unit powers on the water pump 11. Water in the water tank 25, under the suction of the pump, flows through the pipeline via the check valve 27, the water pump 11, and the flow sensor 8 into the washing tub 3. When the central processing unit detects through the flow sensor 8 that the amount of water flowing into the washing tub 3 has reached the rated value, the central processing unit issues a stop water-addition command to the water pump 11. The water pump 11 is immediately de-energized, and the system enters the cleaning phase. The central processing unit then powers on the drive motor 7. The machine starts washing clothes by rotating forward at low speed for 15 seconds and then reverse for 15 seconds according to the preset software program. At this time, the turbine-shaped washing wheel 9 above the drive motor 7 shaft starts to rotate, which makes the water containing the washing liquid in the washing tub 3 rotate and form a vortex inside the washing tub 3. The rotating vortex can drive the clothes to rotate and tumble. When the clothes rotate, they will hit the multiple protrusions 302 on the inside of the washing tub 3, which will generate huge friction. Through orderly forward and reverse rotation for a set time, the clothes are continuously thrashed and rubbed back and forth on the protrusions 302 to clean them.

[0056] After the rated washing time is completed, the system enters the drainage stage. The central processing unit de-energizes and stops the drive motor 7, and issues a drainage command. The water supply and drainage solenoid valve 802 is energized and opens for the rated time. The wastewater in the washing tub 3 is discharged to the outside of the machine through the drainage pipe via the drainage solenoid valve 802. The drainage solenoid valve 802 is connected to the drain pipe to direct the wastewater into the user's sewer or other wastewater storage place. After the rated drainage time is completed, the system enters the rinsing stage. The central processing unit energizes the water pump 11 to inject the rated amount of water into the washing tub 3 from the water storage tank 25. When the central processing unit detects through the flow sensor 8 that the amount meets the rated amount, the central processing unit de-energizes the water pump 11 to stop water injection. At the same time, the central processing unit energizes the drive motor 7, and the drive motor 7 starts to rotate forward at low speed for 15 seconds and then reverse for 15 seconds to rinse the clothes according to the preset software program. After the rinsing operation reaches the rated time, the central processing unit... The drive motor 7 is de-energized and stops operating. At the same time, the central processing unit's water supply and drainage solenoid valve 802 is energized to open the drainage system. The wastewater after rinsing is discharged from the machine through the drainage pipe, completing the first rinse. Then, the same process is repeated to complete the second rinse, followed by a third rinse. During the third rinse, high-temperature sterilization must be performed simultaneously. Users can select the appropriate washing mode when starting the machine, such as the "Gentle Clean" mode, which is suitable for fabrics that are not heat-resistant or cannot be vigorously rubbed, such as silk and lace. High-temperature sterilization cannot be used during this mode; instead, UVC ultraviolet light sterilization is performed after water is added. The UVC ultraviolet sterilization lamp 12 uses UVC ultraviolet light and ozone. The "Super Fast Wash" mode is mainly for clothes that are not particularly dirty, such as those with light sweat stains or dust. Due to the short time, high-temperature washing is not used, and sterilization is also performed using UVC ultraviolet light sterilization. The UVC ultraviolet sterilization lamp 12 uses UVC ultraviolet light sterilization.

[0057] It should be noted that the heating plate 16 can heat the water inside the washing tub 3 to different sterilization temperatures. The 65-degree high-efficiency sterilization mode is mainly for everyday clothing washing, with a moderate washing time. The high-temperature boil-wash mode only heats the water to 65 degrees Celsius, completing the wash quickly while effectively sterilizing most bacteria and viruses. The 90-degree and above strong sterilization washing mode is mainly for heavily soiled or contaminated clothing, or clothing for people with allergies, such as women's underwear with significant menstrual discharge, and diapers and clothes for newborns. These items require a longer washing time, and the water temperature needs to be heated to above 90 degrees Celsius for high-temperature sterilization. Specifically, after the water pump 11 fills the washing tub 3 with water, the central processing unit energizes the relay to connect the power supply to the heating plate 16, which then begins to heat the water inside the washing tub. A temperature sensor 161 is provided to monitor the water temperature. The temperature sensor 161 circuit is connected to the central processing unit. When the water in the washing tub is heated to the rated temperature for each mode, it will send a signal to the central processing unit. After the central processing unit detects this, it will cut off the power to the relay to stop the heating plate 16 and stop heating. At the same time, the central processing unit will power on the drive motor 7, and the drive motor 7 will continue to complete the final rinse and high-temperature sterilization. After draining the water, it will enter the final stage of spin-drying the clothes. At this time, the central processing unit will drive the drive motor 7 to a high-speed running state, and the drain solenoid valve 802 will continue to be open. The high-speed running drive motor 7 will continuously hit the clothes against the protrusions 302 on the inner wall of the washing tub 3 to spin off the residual water in the clothes. The spun water will be discharged to the outside of the machine through the drain solenoid valve 802, and the washing work will be completed.

[0058] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
