Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, in particular to a double-drum fully automatic washing machine. Background Art

[0002] With the improvement of living standards and the accelerated pace of life, washing machines have become an indispensable household appliance in modern families. Common washing machines on the market are mainly divided into single-drum and twin-drum models. Although simple to operate and relatively inexpensive, single-drum models can easily cause cross-contamination when washing different types of clothing simultaneously. For example, when washing both clothing and baby clothes, bacteria and viruses on the clothes can spread, affecting the cleanliness and hygiene of the clothes. This poses a significant health hazard for family members with allergies or when washing baby clothes.

[0003] Although existing twin-tub washing machines have solved the problem of classified washing of clothes to a certain extent, their water supply and drainage systems often interfere with each other. When filling water, water enters the two inner drums at the same time, which makes it difficult to accurately control the water level, affecting the washing effect; when draining, the sewage in the two drums cannot be discharged completely independently, and there is still the risk of sewage backflow and mixing, and cross-contamination cannot be completely avoided. In addition, during the operation of the washing machine, vibration and noise problems have always been key factors affecting the user experience. During the washing and dehydration stages of traditional washing machines, the motor directly drives the inner drum to rotate at high speed, which generates large vibrations and easily causes the body to shake, which not only affects the washing effect, but may also damage key components inside the washing machine and increase maintenance costs. In addition, the large operating noise will interfere with the home environment and reduce user satisfaction.

[0004] Based on this, those skilled in the art have proposed a double-drum fully automatic washing machine to solve the above problems. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a double-drum fully automatic washing machine that solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a double-drum fully automatic washing machine, comprising a casing, a cover plate rotatably mounted on the casing, water tubs with two water holding chambers mounted side by side inside the casing, each water tub being fixedly connected to the casing by three springs, the springs being used to buffer the vibrations generated by the water tub during operation of the washing machine to maintain the stability of the water tub, a dehydration drum being provided inside each of the water tubs, a gap being present between the dehydration drum and the inner wall of the water tub, a washing motor being installed at the outer bottom of each of the water tubs, the washing motor being coaxially arranged with the dehydration drum, a washing shaft being fixedly connected to the output end of the washing motor, the top end of the washing shaft extending into the water tub and being fixedly connected to a pulsator, the pulsator being used for In order to stir the water flow during the washing process, a dehydration shaft that can rotate relatively is installed on the outside of the washing shaft, and a bearing seat is installed on the outside of the dehydration shaft. The dehydration shaft realizes relative rotation with the washing shaft through the bearing inside the bearing seat. A tooth is slidably installed on the bottom of the bearing seat, and a groove matching the dehydration shaft is provided on the inner side of the tooth. Two clutch switching motors are symmetrically installed on the inner side of the water tub, and the output end of the clutch switching motor is fixedly connected to a driving cam. A shift fork is installed on the inner side of the water tub through a rotating shaft, and a return spring is installed on the top of the fork and the inner side of the tooth. The clutch switching motor drives the driving cam to rotate, and cooperates with the action of the shift fork and the tooth to realize power connection or disconnection between the dehydration shaft and the washing shaft, thereby smoothly switching the washing and dehydration modes.

[0007] Through the above technical solution, by setting up a double-drum structure, an independent water supply and drainage system, the coordination of the washing motor and the impeller, the clutch switching mechanism, and the synergy of the teeth and the dehydration shaft, the classified washing of different types of clothes is achieved, effectively avoiding cross-contamination, and at the same time ensuring the stable operation and high efficiency of the washing machine during the washing and dehydration process, providing users with a healthy, convenient and stable laundry solution.

[0008] Preferably, an electric heating pipe is installed at the bottom of the water tub, and the electric heating pipe is connected to a control panel via a wire, and the control panel is used to control the overall operation of the washing machine.

[0009] Through the above technical solution, the water in the barrel is heated during the washing process to meet the user's needs for washing at different water temperatures, improve the decontamination effect and washing quality, and is particularly suitable for clothes that require high-temperature disinfection or cleaning of stubborn stains. The control panel is responsible for precise control of the electric heating tube to ensure the overall intelligent and efficient operation of the washing machine.

[0010] Preferably, the cover is provided with a touch-type operation interface, which has a built-in intelligent control program and can preset multiple washing modes.

[0011] Through the above technical solution, the touch-screen operation interface set on the cover has a built-in intelligent control program, which can preset multiple washing modes. Its function is to facilitate users to choose the appropriate washing method according to different clothing materials, degree of stains, etc., to achieve personalized laundry needs, and at the same time improve the operation convenience and intelligence level of the washing machine.

[0012] Preferably, the drainage spool is connected to a drainage valve via an internal drainage pipe, the drainage valve is driven by a drainage motor to open or close the valve, and the drainage spool is connected to the outside of the casing via an overflow pipe.

[0013] This technical solution achieves efficient wastewater drainage by installing a drain spool at the bottom of each tub, connecting the internal drain pipe to the drain motor, and then discharging the wastewater through the drain valve and overflow pipe. The drain motor serves as the power source, ensuring smooth wastewater discharge, while the overflow pipe automatically drains the water when the water level is too high, preventing overflow and ensuring normal operation of the washing machine and a clean user environment.

[0014] Preferably, a second counterweight and a first counterweight are provided on the inner side of the water tub from top to bottom in sequence. The second counterweight and the first counterweight are irregularly shaped and are used to balance the weight of the water tub and move the center of gravity of the water tub downward, thereby enhancing the stability of the entire machine.

[0015] Through the above technical solution, the weight of the water tub is balanced and its center of gravity is lowered, thereby enhancing the stability of the entire washing machine and preventing shaking due to unstable center of gravity during operation.

[0016] Preferably, a water inlet valve is provided on one side of the housing, and the water inlet valve is connected to the nozzle body through an internal water inlet pipe. The nozzle body is located above the water tub and is used to spray water into the water tub.

[0017] Through the above technical solution, by increasing the weight on the side of the water tub, a balance is formed with the weight of the clothes and water in the tub, preventing the washing machine from shaking due to uneven load during operation, ensuring that the washing machine as a whole maintains balanced and stable operation.

[0018] Preferably, a plurality of spring shock-absorbing feet are installed at the bottom of the casing, and the spring shock-absorbing feet are used to reduce the vibration of the washing machine when it is in operation.

[0019] The above technical solution can reduce the vibration generated by the washing machine during operation. When the washing machine's motor drives the pulsator or spin drum to operate at high speed, vibration is inevitable. The spring shock-absorbing feet can effectively absorb and buffer these vibrations through their elastic properties, reducing the shaking amplitude of the washing machine body.

[0020] Preferably, the shift fork is arranged at an angle, and the distance from the top of the shift fork to the rotating shaft is greater than the distance from the rotating shaft to the bottom of the shift fork.

[0021] With this technical solution, the shift fork's tilted position ensures that the distance between its top and the rotating shaft is greater than the distance between the rotating shaft and the bottom of the shift fork. When the clutch switching motor drives the drive cam to rotate, the drive cam can more easily push one end of the shift fork upward, thereby moving the other end of the shift fork downward, pushing the tooth to engage with the dehydration shaft.

[0022] Preferably, the dehydration shaft is fixedly connected to the dehydration cylinder, and the dehydration shaft is used to control the rotation of the dehydration cylinder.

[0023] Through this technical solution, the high-speed rotation of the spin drum generates centrifugal force, which removes moisture from the clothes, achieving efficient dehydration. The fixed connection between the spin shaft and the spin drum ensures direct and efficient power transmission, avoiding problems such as reduced dehydration efficiency or equipment damage caused by loose or slipping connections during high-speed rotation.

[0024] Preferably, the power adapter is installed in the bottom area inside the casing, and the power adapter is electrically connected to the control board.

[0025] Through the above technical solution, the voltage of the external power supply is converted into the low-voltage direct current required by the control panel and other electrical components, ensuring the normal operation of various electrical systems of the washing machine.

[0026] The present invention provides a double-drum fully automatic washing machine. It has the following beneficial effects:

[0027] 1. By providing two separate water tubs, each equipped with a completely independent water inlet and drainage system, different types of clothing can be washed separately, effectively avoiding cross-contamination. This design not only provides users with a healthier and more hygienic laundry environment, especially suitable for washing baby clothes or family members with allergies, but also avoids unnecessary mixed washing, reducing the number of repeated washes caused by clothing contamination, thereby reducing energy and water consumption.

[0028] 2. The multiple sets of spring damping feet and the precise power transmission of the tooth clutch significantly enhance the stability of the entire machine. During the washing and spinning processes, the vibration amplitude and operating noise are effectively reduced, which not only improves the user experience, but also effectively extends the service life of the key components of the washing machine and reduces maintenance costs.

[0029] 3. When water enters the tub, it creates a high-pressure spiral flow that flushes along the inner wall, achieving a self-cleaning function. This design reduces dirt accumulation on the tub walls, lowering the risk of bacterial growth. It also reduces the frequency and intensity of manual cleaning, making maintenance easier and ensuring a clean interior even after long-term use, ensuring hygienic laundry.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Please see the attached Figure 1 -Attached Figure 6An embodiment of the present invention provides a twin-drum fully automatic washing machine, comprising a housing 1, characterized in that a cover plate 2 is rotatably mounted on the housing 1, and water tubs 15 having two water storage chambers are mounted side by side inside the housing 1, each water tub 15 being fixedly connected to the housing 1 via three springs, and springs 7 being used to buffer the vibration generated by the water tub 15 during operation of the washing machine to maintain the stability of the water tub 15, and a dehydration drum 16 is disposed inside each water tub 15, with a gap between the dehydration drum 16 and the inner wall of the water tub 15, and a washing motor 4 is mounted on the outer bottom of each water tub 15, the washing motor 4 being coaxially arranged with the dehydration drum 16, and the output end of the washing motor 4 being fixedly connected to a washing shaft 24, the top end of the washing shaft 24 extending into the interior of the water tub 15 and being fixedly connected to a pulsator 20, which is used to agitate during the washing process. Water flow, a dehydration shaft 26 that can rotate relatively is installed on the outside of the washing shaft 24, and a bearing seat 23 is installed on the outside of the dehydration shaft 26. The dehydration shaft 26 realizes relative rotation with the washing shaft 24 through the bearing inside the bearing seat 23. A tooth 25 is slidably installed on the bottom of the bearing seat 23, and a groove matching the dehydration shaft 26 is provided on the inner side of the tooth 25. Two clutch switching motors 19 are symmetrically installed on the inner side of the water tub 15. The output end of the clutch switching motor 19 is fixedly connected to a driving cam. A fork 21 is installed on the inner side of the water tub 15 through a rotating shaft. A return spring is installed on the top of the fork 21 and the inner side of the tooth 25. The driving cam is driven to rotate by the clutch switching motor 19, and the action of the fork 21 and the tooth 25 can realize the power connection or disconnection between the dehydration shaft 26 and the washing shaft 24, thereby smoothly switching the washing and dehydration modes.

[0039] Specifically, the casing 1 serves as the outer frame of the entire washing machine, supporting and protecting the various internal components. It also provides a relatively enclosed working environment, preventing water and clothing from splashing out and ensuring stable operation. A cover 2 is rotatably mounted on the casing 1, allowing the user to open it when needed to load and unload clothing. The water tub 15 holds the laundry and wash water, providing a space for washing. A gap exists between its inner wall and the spin drum 16, facilitating smooth rotation and drying of the laundry during the spin cycle. The spin drum 16 is located within the water tub 15, with a gap between the inner wall and the drum. During the spin cycle, the spin drum 16 rotates at high speed, using centrifugal force to remove moisture from the laundry, effectively dehydrating the laundry. The output end of the washing motor 4 is fixedly connected to the washing shaft 24. Rotating the washing shaft 24 drives the pulsator 20, ensuring thorough agitation of the laundry within the water tub 15 for efficient washing. The pulsator 20 is mounted at the top of the washing shaft 24, within the water tub 15. During the washing process, the pulsator 20 rotates and stirs the water flow, simulating the action of manual scrubbing, so that the clothes are fully in contact with the water flow, thereby achieving the effect of removing dirt.

[0040] The bearing seat 23 supports and stabilizes the washing shaft 24, ensuring that the washing shaft 24 remains stable during rotation, reducing vibration and shaking, and extending the service life of the washing shaft 24 and related components. The dehydration shaft 26 is connected to the washing shaft 24 via two bearings. This structural design allows the dehydration shaft 26 to work in conjunction with the washing shaft 24 or independently when needed to achieve the dehydration function. The dehydration shaft 26 is fixedly connected to the dehydration drum 16. When the dehydration shaft 26 rotates, it drives the dehydration drum 16 to rotate at high speed to complete the dehydration operation. The inner side of the tooth 25 is provided with a groove that matches the dehydration shaft 26. With the cooperation of the clutch switching motor 19 and the shift fork 21, the tooth 25 can engage or disengage with the dehydration shaft 26, thereby controlling the power transmission relationship between the dehydration shaft 26 and the washing shaft 24 and realizing the switching between the washing and dehydration modes.

[0041] The shift fork 21 is rotatably mounted on the inside of the housing 1 via a rotating shaft. Return springs are installed on its top and on the inside of the tooth 25. Driven by the clutch switching motor 19 and the return spring, the shift fork 21 pushes the tooth 25 to move, connecting and disconnecting the spin shaft 26 and the wash shaft 24, ensuring stable operation in different operating modes.

[0042] An electric heating tube 22 is installed at the bottom of the water tub 15, and the electric heating tube 22 is connected to the control board 27 through a wire. The control board 27 is used to control the overall operation of the washing machine. A touch operation interface is provided on the cover 2, which has a built-in intelligent control program and can preset multiple washing modes.

[0043] Specifically, the electric heating tube 22 heats the water in the tub during the washing process. Controlled by the control panel 27, the electric heating tube 22 can raise the water temperature to the set temperature, significantly improving the washing effect while also meeting the user's diverse washing needs, such as selecting the appropriate water temperature for washing clothes made of different materials. The control panel 27 is responsible for controlling the overall operation of the washing machine. It can precisely control each component according to a preset program, including but not limited to starting and stopping the washing motor 4, adjusting the speed of the impeller 20, controlling the heating of the electric heating tube 22, draining the water from the drain motor 8, and switching the clutch switching motor 19. The intelligent control of the control panel 27 enables the washing machine to perform a variety of complex washing functions, providing users with a convenient and efficient washing experience.

[0044] The washing machine also includes a drain motor 8. A drain spool 5 is connected to the bottom of each water tub 15. This spool 5 is connected to a drain valve 10 via an internal drain pipe 9. The drain valve 10 is driven by the drain motor 8 to open and close. The drain spool 5 is connected to the exterior of the casing 1 via an overflow pipe 11. A water inlet valve 12 is installed on one side of the casing 1. This inlet valve 12 is connected to a spray head 14 via an internal inlet pipe 13. The spray head 14 is located above the water tub 15 and is used to spray water into the tub 15. Multiple spring-loaded shock-absorbing feet 7 are installed at the bottom of the casing 1 to mitigate vibrations during operation.

[0045] Specifically, the water inlet valve 12 is the switch that controls water inflow. The user can set water inlet parameters via the control panel 27. The water inlet valve 12 opens or closes according to the control panel 27, controlling the amount of water entering and ensuring the water level in the water tub 15 meets washing requirements. The internal water inlet pipe 13 connects the water inlet valve 12 to the showerhead 14, transporting fresh water introduced by the water inlet valve 12 to the showerhead 14.

[0046] The nozzle body 14 is used to evenly spray the clean water delivered by the inner water inlet pipe 13 onto the clothes in the water tub 15, so that the clothes are fully soaked and ready for the subsequent washing process. The design of the nozzle body 14 can ensure that the water flow is evenly distributed, improve the soaking effect of the clothes, and optimize the washing effect.

[0047] The inner side of the water tub 15 is provided with a counterweight block 2 18 and a counterweight block 1 3 from top to bottom. The counterweight block 2 18 and the counterweight block 1 3 are irregularly shaped and are used to balance the weight of the water tub 15 and move the center of gravity of the water tub 15 downward, thereby enhancing the stability of the entire machine.

[0048] The shift fork 21 is tilted, and the distance from the top of the shift fork 21 to the rotating shaft is greater than the distance between the rotating shaft and the bottom of the shift fork 21. The dehydration shaft 26 is fixedly connected to the dehydration cylinder 16, and the dehydration shaft 26 is used to control the rotation of the dehydration cylinder 16.

[0049] Specifically, when the clutch switching motor 19 drives the drive cam to rotate, the raised portion of the drive cam effectively pushes one end of the shift fork 21 upward. Due to the tilted design of the shift fork 21, its other end moves downward accordingly. This design allows for more precise control of the depth and force of engagement between the jaws 25 and the dehydration shaft 26, ensuring reliable and smooth power transmission during the clutch switching process. Furthermore, the tilted shift fork 21 allows for a greater range of motion within a limited space, improving the efficiency and flexibility of the entire clutch switching mechanism.

[0050] The housing 1 further includes a power adapter 6 , which is installed in the bottom area inside the housing 1 and is electrically connected to the control board 27 .

[0051] Specifically, the power adapter 6 converts the voltage of the external power supply into low-voltage direct current required by the control board 27 and other electrical components, ensuring that the various electrical systems of the washing machine can operate normally.

[0052] Working principle: When using this device, it includes the following operating principles:

[0053] After placing clothes in tub 15, the user starts the washing machine via the touchscreen interface. A signal from control panel 27 opens water inlet valve 12, allowing water to flow in through internal inlet pipe 13 and reach nozzle body 14. Nozzle body 14 evenly sprays water into tub 15, thoroughly soaking the clothes. Simultaneously, the high-pressure water flow from nozzle body 14 creates a spiraling motion along the inner wall of the tub, providing a self-cleaning effect.

[0054] The washing motor 4 is powered on and started, and its output end drives the washing shaft 24 to rotate. The pulsator 20 on the washing shaft 24 rotates accordingly, vigorously stirring the clothes in the barrel, simulating the manual scrubbing action to remove the dirt on the clothes.

[0055] If the hot water washing mode is selected, the control panel 27 controls the electric heating tube 22 at the bottom of the water tub 15 to energize and heat the water to the set temperature, thereby improving the dirt removal effect, which is especially suitable for clothes with stubborn stains or requiring high-temperature disinfection.

[0056] After washing is complete, control panel 27 activates drain motor 8. Wastewater in tub 15 is collected through drain spool 5 and flows through internal drain pipe 9 into drain motor 8. Drain motor 8 pumps the wastewater out through drain valve 10. Overflow pipe 11 automatically drains the wastewater if the water level is too high, preventing overflow.

[0057] After drainage is completed, the water inlet valve 12 is opened again, and clean water flows into the water tub 15. At this time, the pulsator 20 stirs the water flow at a lower speed to rinse the clothes and remove residual detergent.

[0058] After rinsing is complete, the control panel 27 activates the clutch motor 19. The clutch motor 19 rotates the drive cam. When the cam's protrusion contacts the end of the drive fork 21, it tilts one end of the drive fork 21 upward, causing the other end of the drive fork 21 to move downward. The drive fork 21, in conjunction with the return spring on the tooth 25, pushes the tooth 25 downward, causing the tooth 25 to slide and engage with the groove on the spin shaft 26. Because the spin shaft 26 is fixedly connected to the spin drum 16, when the tooth 25 engages the spin shaft 26, the wash shaft 24 drives the spin shaft 26 to rotate at high speed, causing the spin drum 16 to rotate rapidly. This centrifugal force removes water from the clothes, achieving efficient dehydration. The removed water is discharged through the drainage system. When the convex part of the driving cam is not in contact with the end of the driving fork 21, under the elastic force of the return spring on the driving fork 21, one end of the fork 21 is driven to move upward, and then the tooth 25 at the other end of the fork 21 is driven to move downward, completing the switching.

[0059] In hot water washing mode, after washing is complete, control panel 27 activates drain motor 8 to drain the hot water from tub 15. Because the hot water is relatively hot, to prevent damage to the drainage system or potential safety hazards, the washing machine uses forced cooling to cool the hot water before draining. The cooled hot water is then discharged through drain spool 5, internal drain pipe 9, drain motor 8, and drain valve 10. Overflow pipe 11 automatically drains the water if the water level is too high, preventing overflow.

[0060] During the entire washing and dehydration process, the spring shock-absorbing feet 7 at the bottom of the housing 1 effectively buffer the vibration generated by the operation of the washing machine, prevent the machine body from excessive shaking, reduce noise, and extend the service life of components.

[0061] The counterweights 1 3 and 2 18 on the outside of the tub 15 are connected to the housing 1 via the mounting bracket 17. Depending on the load conditions, the counterweights form a dynamic balance with the tub 15 and the clothes inside, ensuring smooth operation of the washing machine and avoiding damage caused by polarization.

[0062] The control panel 27 monitors the operating status of various components in real time, such as water level, temperature, and motor speed. It automatically switches between wash, rinse, and spin modes according to pre-set programs, optimizing wash time and energy consumption and enhancing the user experience. The touch-sensitive interface allows users to select personalized wash plans based on different fabrics and soiling levels.

[0063] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
