[0002] Front-loading washing machines are the most commonly used washing machines nowadays. They are generally composed of a stainless steel inner tub, a program controller, an outer shell, and a heavy cement block for balance. When in use, laundry detergent or liquid detergent and water are added, and the huge centrifugal force generated by the rotation of the drum washes the clothes, making them clean.

[0003] With the development of society and economy and the improvement of living standards, people's awareness of hygiene has gradually increased, and they are paying more attention to their own health. Clothing sorting and washing has become a trend. Many users sort their clothes for washing, such as washing inner and outer garments separately, washing baby and adult clothes separately, washing clothes with different levels of soiling separately, and washing clothes of different colors separately. At present, since families have a lot of different types of clothes, if all the clothes are put in one washing machine for mixed washing, the risk of coloring will increase. In addition, washing different clothes separately multiple times and then draining the washing water after dehydration will waste water resources and increase living costs.

[0004] In view of the above factors, a multi-drum washing machine is provided, which can not only achieve the purpose of sorting and washing clothes to meet people's personalized requirements, but also achieve water-saving effect. Summary of the Invention

[0023] like Figure 1-11As shown, a multi-drum washing machine includes a circular door 2 connected to an outer casing 1 by a hinge. A controller 3 is also provided on the upper side of the outer casing 1. The outer casing 1 includes at least three sets of parallel washing drum assemblies 4. The parallel washing drum assemblies 4 are electrically connected to the controller 3. The controller 3 includes a computer chip, a control panel, and control buttons. (The controller 3 is a prior art form and will not be described in detail here. The door lock locking method between the circular door and the outer casing adopts a prior art form and will not be described in detail here.) It also includes a liquid storage tank 5 disposed on the outside of the outer casing 1. The liquid storage tank 5 is connected to the external drain pipe branch pipe 6 of the three sets of parallel washing drum assemblies 4. The liquid storage tank 5 is also provided with a water inlet pipe 7 connected to the other washing drum assemblies 4 on the outer casing 1 except for the first washing drum assembly 4. The washing tub assembly 4 includes an outer tub 8 and an inner washing tub 9. The outer tub 8 is connected and fixed to the outer casing 1 by an outer tub fork bracket 10. The inner washing tub 9 is coaxially arranged with the outer tub 8, and the inner washing tub 9 is rotated by a drive assembly 11.

[0024] The inner washing drum 9 is connected to the outer drum 8 via an inner drum fork frame. The outer drum 8 is used to hold the washing liquid and also serves as a support. The outer drum is made of high-quality steel plate and the surface is enamel treated.

[0025] The outer cylinder 8 is equipped with a fork-shaped frame that supports the cylinder body. It is formed by die casting of aluminum alloy. The fork-shaped frame and bushing of the inner washing cylinder 9 are cast as one piece and then fixed to the rear end face of the inner washing cylinder 9 with bolts to support the inner washing cylinder 9. The outer cylinder 8 is equipped with a fork-shaped frame that supports the cylinder body. There is also a bearing bracket connected to the outside of the center hole of the fork-shaped frame of the outer cylinder. The main shaft of the inner washing cylinder 9 passes through the center hole of the fork-shaped frame of the outer cylinder and then through the bearing inner hole of the bearing bracket. A pulley is installed at the shaft end. The pulley is connected to the motor pulley through the transmission belt. When the motor runs, the inner washing cylinder rotates.

[0026] To reduce vibration of the machine during washing and spin-drying, a counterweight (not shown in the figure) is fixed on the outer cylinder 8.

[0027] In order to ensure that the washing tub assembly 4 can work independently during use, each washing tub assembly 4 is independently provided with a water supply device 12 and a drainage device 13, and the water supply device 12 and the drainage device 13 are electrically connected to the controller 3. The water supply device 12 includes a water inlet channel 12A disposed inside the outer casing 1. One end of the water inlet channel 12A is connected to an external faucet, and the other end of the water inlet channel 12A is connected to a detergent box 12B. The detergent box 12B is connected to the washing drum assembly 4. The liquid storage tank 5 is also provided with a water inlet pipe 7 that is connected to the detergent box 12B on the outer casing 1. The drainage device 13 includes an external drainage pipe 13A that communicates with the outer cylinder 8. A pipe filter 13B is installed on the external drainage pipe 13A. The pipe filter 13B is connected to a branch pipe 6 of the external drainage pipe, and the branch pipe 6 of the external drainage pipe is connected to the liquid storage tank 5.

[0028] In order to facilitate the operation of the washing drum by driving the drive assembly during use, the drive assembly 11 includes a dual-speed motor 11A. The output end of the dual-speed motor 11A is connected to a pulley 11C through a triangular transmission belt 11B. The pulley 11C is connected to the rotating shaft of the washing drum 9.

[0029] A pipeline pump is installed on the water inlet pipe 7 provided on the liquid storage tank 5, and the pipeline pump is electrically connected to the controller 3; The liquid storage tank 5 is provided with a washing liquid filling chamber 14, which is connected to the liquid storage tank 5 through a pipe, and a suction pump is provided on the pipe.

[0030] In use, by setting up a liquid storage tank, it can be ensured that after the first washing drum assembly 4 of the three parallel washing drum assemblies 4 is dehydrated, the liquid is discharged into the liquid storage tank 5, and the liquid in the liquid storage tank 5 is pumped into the second washing drum assembly 4 by the action of the pipeline pump. After the second washing drum assembly 4 is dehydrated, the liquid is discharged into the liquid storage tank 5, and the liquid in the liquid storage tank 5 is pumped into the third washing drum assembly 4 by the action of the pipeline pump, and so on.

[0031] To facilitate the spin-drying of clothes and to allow for friction between the clothes and the lifting ribs, the circumferential surface of the washing drum 9 is evenly distributed with through holes 15, and the inner wall of the washing drum 9 is evenly distributed with lifting ribs 16. The lifting ribs 16 are convex arc-shaped structures and are S-shaped along the axial direction of the washing drum 9.

[0032] The inner wall of the washing drum 9 is covered with round holes with a diameter of 3.5-5 mm, and the distance between adjacent holes is about 15-20 mm. The front center of the inner washing drum 9 has a large round hole for loading and unloading clothes.

[0033] By setting up lifting ribs in the washing drum, on the one hand, the clothes are made to rub against the liquid. The part of the clothes near the lifting ribs rubs against the relatively moving parts, creating a kneading effect. On the other hand, the lifting ribs drive the clothes to rotate together, lifting the clothes out of the liquid and sending them to a certain height. Due to gravity, they fall back into the detergent, colliding with the detergent and creating a beating and tumbling effect, thereby achieving the washing effect.

[0034] To facilitate increasing the washing liquid temperature and washing activity during use, a heating device 17 is provided on the outer drum 8. The heating device 17 is installed at the bottom of the outer drum 8 between the outer drum 8 and the inner washing drum 9. The heating device 17 is arranged in three sets at intervals, and the three sets of heating devices 17 are arranged along the bottom circumference of the outer drum 8. The heating device 17 is a tubular heater structure, and the heating device 17 is electrically connected to the controller 3.

[0035] The three sets of heating devices 17 are arranged such that the first set is located at the lowest position of the outer cylinder 8, and the other two sets are arranged at intervals along the arc of the outer cylinder 8.

[0036] The controller 3 can control the working mode of the three sets of heating devices 17, and can control one set to work alone, or any two sets to work at the same time, or control all three sets to work together.

[0037] The three sets of parallel washing drum assemblies 4 are provided with a number of air nozzles 18 inside. The air nozzles 18 are located on the side wall of the washing drum assembly 4 where washing water is stored. Each air nozzle 18 is connected to an air pump 21 located on the outside of the outer casing 1. To improve the washing effect during use, the jet nozzle 18 includes a disc-shaped body 19, the surface of which is provided with a plurality of jet outlets 20, and the body 19 is provided with an interface 22 that is sealed to the air supply pipe of the air pump 21.

[0038] The surface of the body 19 is provided with a concave arc-shaped structure, and the density of the jet outlet 20 at the center of the arc-shaped structure is greater than the density of the jet outlet 20 on its outer side.

[0039] Each jet outlet 20 is connected to each air supply pipe of the air pump 21 in a sealed manner. The main body 19 is provided with an interface for sealed connection with the air supply pipe of the air pump 21. In order to form a concentrated and more numerous air bubbles ejected from the jet nozzle 18, while having fewer bubbles on the outside, thus forming a tumbling bubble bundle, the surface of the main body 19 is provided with a concave arc-shaped structure. In order to increase the stability of the airflow from the jet outlet 20, the main body 19 is provided with an interface 22 for sealed connection with the air supply pipe of the air pump 21. In order to ensure that the air entering the jet nozzle 18 can be evenly ejected from the jet outlet 20, the main body 19 is provided with a buffer chamber 23 connected to the interface 22 and an air chamber 24 connected to the jet outlet 20. The buffer chamber 23 and the air chamber can play a role in making the airflow from the jet outlet 20 uniform and stable.

[0040] The air pump 21 provides air to the air nozzle 18. The air enters the washing water inside the washing drum assembly 4, generating a large number of bubbles to increase the washing effect. The bubbles generated by the air increase the surface area of ​​the washing water, effectively carrying away dirt under the washing machine. When the air nozzle 18 sprays air for washing, the amount of detergent or washing powder used can be reduced by 1 / 3 or 1 / 2, thereby reducing the amount of chemical detergent in the wastewater and achieving the purpose of environmental protection and energy saving.

[0041] In order to ensure that the airflow from the jet outlet is uniform and stable during use, the body 19 is provided with a buffer cavity 23 communicating with the interface 22 and an air cavity 24 communicating with the jet outlet 20. The air chamber 24 is a spindle-shaped structure that is small at both ends and large in the middle. One end of the spindle-shaped structure is the jet outlet 20, and the other end of the spindle-shaped structure is the jet inlet.

[0042] To improve the stability of the washing drum assembly 4 during use, a support structure is provided between the outer casing 1 and the washing drum assembly 4. The support structure includes an elastic support shock absorber located at the bottom of the outer casing 1. One end of the elastic support shock absorber is connected to the outer casing 1, and the other end of the elastic support shock absorber (existing technology is disclosed and will not be described in detail here) is connected to the outer drum 8 of the washing drum assembly 4. The outer tub 8 of the washing tub assembly 4 is installed as a whole. Four tension springs are installed on the upper part of the outer tub 8 to suspend the outer tub 8 at the four top corners of the outer casing 1. The bottom of the outer tub 8 is supported by two elastic support shock absorbers at the bottom of the outer casing 1.

[0043] The above-mentioned elastic connection allows the vibration of the outer cylinder to be attenuated by the upper tension spring and the lower shock absorber, providing sufficient stability during operation, especially during high-speed rotation in dehydration.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
