Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a water circuit system for a twin-tub washing machine. Background Technology

[0002] As people's living standards improve, their functional needs for washing machines are becoming increasingly diverse. In daily life, users often need to process different types or colors of clothing at the same time, such as dark and light-colored clothes, or ordinary clothes and underwear, to avoid staining and cross-contamination. Therefore, they use twin-tub washing machines to process different types or colors of clothing simultaneously.

[0003] The safe operation of washing machines is also a key concern for users, especially the reliability of the drainage system, which directly affects the lifespan of the washing machine and the safety of household property. However, considering that most traditional washing machines use a single water circuit design, users must wash different types or colors of clothing in batches. This not only wastes a lot of time but also consumes more water during repeated washing. Furthermore, in a single water circuit system, wastewater from different batches of washing can easily mix, leading to cross-contamination of clothes and affecting washing performance and hygiene. Therefore, a twin-tub washing machine water circuit system is proposed to solve these problems.

[0004] In this invention, a special water system is used to fix the nozzle body to the upper outer side of the water tank and connect it along the circumferential tangential direction, so that the water flow forms a high-speed rotating external vortex. The centrifugal force is used to flush the tank wall to achieve self-cleaning and effectively reduce dirt residue. At the same time, the spiral water inlet can quickly reduce the temperature of the wastewater when draining, avoiding high temperature damage to the water pipes. This not only improves the cleaning and maintenance efficiency of the washing machine, but also extends the service life of the water system, combining practicality and economy.

[0023] 2. In this utility model, a special water system is used to fix the nozzle body to the upper outer side of the water tank and connect it along the circumferential tangential direction, so that the water flow forms a high-speed rotating external vortex. Centrifugal force is used to flush the tank wall to achieve self-cleaning and effectively reduce dirt residue.

[0024] 3. In this utility model, users only need one inlet pipe and one outlet pipe to achieve the installation and use effect equivalent to two washing machines, greatly simplifying the installation process and reducing the need for complex pipe layouts. Whether it is new house renovation or old house renovation, it can flexibly adapt to different drainage environments, reducing installation costs and difficulties.

[0025] 4. In this utility model, the four-way drainage design combined with the overflow water channel not only effectively collects the sewage discharged from the two water tanks, but also handles the overflow water. When the machine is running normally, the four-way drainage ensures efficient sewage discharge; if a malfunction causes water to overflow, the overflow water can be discharged through the four-way drainage via a dedicated water channel, avoiding electrical safety hazards and water damage accidents, and comprehensively ensuring the safe operation of the washing machine.

[0026] 5. In this utility model, water is introduced along the tangential direction of the nozzle body around the circumference of the water tank, forming a high-speed rotating external vortex. During the washing process, the dirt on the drum wall is simultaneously washed away, effectively preventing dirt residue from breeding bacteria and achieving self-cleaning of the drum. At the same time, cold water quickly penetrates into the high-temperature wastewater layer in a spiral manner, using centrifugal force to accelerate the hot and cold convection, which promotes the rapid cooling of the high-temperature wastewater. This not only prevents the high-temperature wastewater from damaging the drainage pipes and extends the service life of the water system, but also reduces the energy consumption of subsequent sewage treatment. It has multiple advantages of cleaning, energy saving and safety protection, significantly improving the performance of the washing machine and the user experience. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-2 , Figure 4This utility model provides an embodiment of a water system for a twin-tub washing machine, including a housing 1. The housing 1 serves as the outer shell of the entire washing machine, providing installation space and protection for the internal components. A water tank 6 is fixedly connected to the inner surface of the housing 1. The fixedly connected water tank 6 can stably hold the washing water and clothes, ensuring that the washing machine will not generate noise or affect the washing effect due to the shaking of the water tank 6 during operation. There are two sets of water tanks 6, and the two sets of water tanks 6 are symmetrically arranged on the left and right sides of the inner surface of the housing 1. The two sets of symmetrical water tanks 6 can simultaneously wash different types or colors of clothes, improving washing efficiency. At the same time, the symmetrical distribution design helps to maintain the overall balance of the washing machine and reduce vibration during operation. A nozzle body 1 is fixedly connected to the top of the outer surface of each set of water tanks 6. 5. The nozzle body 15 can evenly spray water into the water tank 6, avoiding concentrated water flow that could cause clothes to tangle. This allows clothes to fully contact water and detergent during washing, improving washing quality. An inner water inlet pipe 10 is fixedly connected to the bottom of the outer surface of the nozzle body 15. The inner water inlet pipe 10 is responsible for guiding the water flow delivered by the water inlet valve 4 to the nozzle body 15. Its reasonable pipe diameter and layout can ensure stable water flow, meet the water spraying needs of the nozzle body 15, and ensure smooth water intake. The water inlet valve 4 is fixedly connected to the bottom of the outer surface of the inner water inlet pipe 10. The water inlet valve 4 is a key component for controlling the water flow into the washing machine. By precisely controlling the opening and closing of the water inlet valve 4, the water intake can be accurately adjusted to achieve the set water level requirements, avoiding water waste and providing a basis for the intelligent control of the washing machine.

[0036] Reference Figure 2 , Figures 4-5The outer surface of the water inlet valve 4 is fixedly connected to the bottom of the outer surface of the housing 1. Fixing the water inlet valve 4 to the bottom of the housing 1 facilitates connection to an external water source and makes the layout of the entire water system more compact and reasonable, facilitating installation and maintenance. A drain motor 18 is fixedly connected to the bottom of the outer surface of the water tank 6. The drain motor 18 serves as a power source, driving the drain valve 13 to ensure that the wastewater in the water tank 6 is discharged in a timely manner when drainage is needed, ensuring the continuity of the washing and spin-drying processes. The output end of the drain motor 18 is fixedly connected to the drain valve 13. The drain valve 13 opens or closes under the drive of the drain motor 18, precisely controlling the drainage process and preventing water leakage in non-draining states, ensuring the stability of the internal environment of the washing machine. An inner drain pipe 9 is fixedly connected to the outer surface of the drain valve 13. The inner drain pipe 9 is used to transport the wastewater discharged from the drain valve 13. The wastewater is fed to the drain four-way valve 8. The drain four-way valve 8 is fixedly connected to the bottom of the outer surface of the casing 1. The drain four-way valve 8 plays the role of diverting and collecting, and can collect the sewage discharged from the two water tanks 6 and the overflow water discharged from the overflow pipe 11. It is then discharged from the washing machine through the drain outlet 5 or the drain connector 22, making the drainage system more efficient and orderly. The drain connector 22 is fixedly connected to the rear of the outer surface of the drain four-way valve 8. The drain connector 22 is convenient to connect to the external drainage pipe, ensuring that the sewage can be discharged smoothly into the sewer. Its connection method is stable and can effectively prevent leakage during the drainage process. The outer surface of the inner drain pipe 9 is fixedly connected to the outer surface of the drain connector 22. This connection method ensures the sealing between the inner drain pipe 9 and the drain four-way valve 8, so that the sewage can flow into the drain four-way valve 8 accurately and without error, avoiding sewage overflow and damage to the inside of the washing machine.

[0037] Reference Figures 3-5 An overflow groove 20 is provided on the top of the outer surface of the water tank 6. The overflow groove 20 can collect the overflowing water in time when the water level in the water tank 6 is too high, preventing water from overflowing directly from the top of the water tank 6 onto other parts inside the washing machine and damaging electrical components, thus ensuring the safe operation of the washing machine. An overflow hole 21 is provided on the bottom of the inner surface of the overflow groove 20. The overflow hole 21 provides a channel for the overflowing water, allowing the water collected in the overflow groove 20 to flow smoothly into the overflow pipe 11. The overflow pipe 11 is fixedly connected to the outer surface of the overflow hole 21, and the overflow pipe 11 will carry the overflowing water. Water discharged from hole 21 is delivered to drain four-way valve 8. An overflow connector 23 is fixedly connected to the top of the outer surface of drain four-way valve 8. Overflow connector 23 is used to connect overflow pipe 11 and drain four-way valve 8. Its stable connection method can ensure that overflow water can smoothly enter drain four-way valve 8. The bottom of the outer surface of overflow pipe 11 is fixedly connected to the top of the outer surface of overflow connector 23, which ensures the sealing and connection stability between overflow pipe 11 and drain four-way valve 8, so that overflow water can flow smoothly from overflow pipe 11 into drain four-way valve 8, effectively avoiding overflow water from damaging the inside of washing machine.

[0038] Reference Figure 2 , Figure 4 A water level sensor 17 is fixedly connected to the top of the outer surface of the water tank 6. The water level sensor 17 can monitor the water level in the water tank 6 in real time and feed the water level information back to the washing machine's control system. The control system precisely controls the opening and closing of the water inlet valve 4 based on the feedback signal from the water level sensor 17, realizing automatic water intake and water level control, making the washing machine's operation more intelligent and energy-efficient. The outer surface of the water level sensor 17 is fixedly connected to the top of the outer surface of the water tank 6 through an air pressure conduit 16. The air pressure conduit 16 is used to transmit changes in air pressure inside the water tank 6, enabling the water level sensor 17 to accurately sense the water level. Its material and connection method can ensure the accuracy and stability of air pressure transmission, ensuring the precision of water level monitoring.

[0039] Reference Figure 3 A washing motor 14 is fixedly connected to the bottom of the outer surface of the water tank 6. The output shaft of the washing motor 14 is fixedly connected to the spin-drying tub 19. The washing motor 14 provides power for the washing process of the washing machine. By driving the spin-drying tub 19 to rotate, the clothes are continuously tumbled and rubbed inside the water tank 6, achieving effective washing of the clothes. The outer surface of the spin-drying tub 19 is rotatably connected to the inner surface of the water tank 6, ensuring that the spin-drying tub 19 can rotate flexibly inside the water tank 6. It also plays a certain supporting and positioning role, keeping the spin-drying tub 19 stable during high-speed rotation and reducing vibration and noise.

[0040] Reference Figures 1-3A spring-loaded shock-absorbing foot 7 is fixedly connected to the bottom of the outer surface of the water tank 6. This foot effectively absorbs vibrations generated during washing machine operation, reducing the transmission of vibrations to the ground, lowering noise levels, and protecting internal components from vibration damage, thus extending the washing machine's lifespan. The bottom of the outer surface of the spring-loaded shock-absorbing foot 7 is fixedly connected to the bottom of the inner surface of the housing 1. This connection ensures the stable installation of the spring-loaded shock-absorbing foot 7, allowing it to fully exert its shock-absorbing effect and ensuring the stability of the water tank 6 during washing machine operation. A plug 3 is fixedly connected to the bottom of the outer surface of the housing 1, connecting the washing machine to an external power source to provide power for its operation. Two sets of drain connectors 22 are provided, each corresponding to the drainage needs of one of the two water tanks 6, allowing the wastewater from the two tanks 6 to drain independently. To prevent mutual interference and improve drainage efficiency, the drain four-way valve 8 has a drain outlet 5 on its front surface, which serves as the final outlet for wastewater to be discharged from the washing machine. The top of the outer surface of the cabinet 1 is hinged with a door cover 2, which is used to open and close the washing machine for easy loading and unloading of clothes. The hinged design allows the door cover 2 to open and close flexibly. When the door cover 2 is closed, it can prevent water and detergent from splashing out during the washing process. The door cover has a small gap where it fits against the cabinet 1 to prevent a vacuum from forming inside when the door is opened, which would make it difficult to open the door. At the same time, it can also allow the buzzer sound on the main control board to be heard by the user, increasing the buzzer volume so that the user can hear it immediately from a distance when the washing is complete or other alarms are triggered, thus ensuring a clean and safe washing environment.

[0041] Reference Figures 2-4 The nozzle body 15 is fixedly connected to the upper outer side of the water tank 6 and is aligned with the circumferential tangent direction of the water tank 6. This design allows tap water to enter the water tank 6 and directly form a high-speed rotating outer vortex by contacting the arc-shaped inner surface of the water tank 6. The centrifugal force of the water flow can effectively flush and clean the inner surface of the water tank 6. Furthermore, through this spiral water inlet, the wastewater in the water tank 6 can be quickly cooled down when it is discharged at a higher temperature.

[0042] Working principle: The water inlet valve 4 acts as a control switch for water flow into the washing machine, precisely controlling the water inlet time and flow rate to ensure that the water volume meets the set requirements and avoids water waste. Then, the tap water is sprayed into the water tank 6 by the two sets of nozzles 15 on the two sets of inner water inlet pipes 10 on the water inlet valve 4. The water flow into the water tank 6 spirals along the inner wall of the water tank 6 to the bottom of the water tank 6. Then, the water flow seeps into the inner drum through the small holes on the outer wall of the spin-drying drum 19 to wet the clothes. Then, the washing machine is started to wash the clothes. When draining, the inlet valve 4 is activated first, allowing external cold water to enter from the top of the water tank 6. Because the nozzle body 15 is positioned tangentially to the circumference of the water tank 6, the external cold water forms a spiral flow by contacting the curved surface inside the water tank 6, quickly cooling the wastewater inside. This prevents damage to the water pipes due to high temperatures during discharge. Then, the drain motor 18 is activated, allowing water from the water tank 6 to drain through the drain valve 13 along the inner drain pipe 9 into the drain valve 8, ensuring rapid and thorough drainage and smooth operation of the washing and dehydration processes. The wastewater is discharged through the drain outlet 5 on the drain valve 8. The well-designed drain valve 8 concentrates and smoothly discharges wastewater from both water tanks 6, and the layout and size of the drain outlet 5 ensure smooth drainage and prevent wastewater residue.

[0043] When the machine malfunctions and overflows, the water overflowing from the container 6 flows into the overflow tank 20. The overflow tank 20 collects the overflowing water promptly, preventing it from spreading to other components inside the washing machine and damaging electrical components, thus ensuring the electrical safety of the washing machine. The water then drains into the overflow pipe 11 through the overflow hole 21 at the bottom of the overflow tank 20. The overflow hole 21 provides a dedicated drainage channel for the overflowing water, ensuring that the overflowing water can quickly drain out of the overflow tank 20 and prevent excessive water accumulation. Water entering the overflow pipe 11 will also be discharged outside the machine through the drain four-way connector 8 because the bottom of the overflow pipe 11 is connected to the overflow connector 23 at the top of the drain four-way connector 8. This prevents electrical safety and water damage accidents. The overflow system design effectively prevents various safety hazards that may be caused by overflowing water, improving the safety and reliability of the washing machine.
