Description

Technical Field

[0001] This invention belongs to the field of fully automatic textile washing machinery, and specifically relates to a two-hand hand-washing washing machine. Background Technology

[0002] Currently, the mainstream structures of washing machines on the market can be divided into two types: top-loading washing machines and front-loading washing machines. The so-called "hand-washing" washing machine simply uses an inner drum and a top-loading impeller rotating in opposite directions. Several metal protrusions are set on the inner drum wall, which act as a washboard to rub against the surface of the fabric to remove stains. In short, none of the washing machines currently in use have changed the motion mode of surface rotation rubbing against the fabric. The biggest drawback of this motion mode is that in order to wash away a small stain on the fabric, the entire fabric must be rubbed repeatedly. Excessive friction can easily cause clothes to tangle, and even with long-term friction, it is difficult to clean the stains inside the clothes. It is energy-consuming and time-consuming, and is not suitable for washing silk and wool fabrics.

[0003] To address the shortcomings of the aforementioned washing machine modes, this invention provides a two-handed hand-washing washing machine. Summary of the Invention

[0004] A fully automatic dual-hand washing machine includes the following main components: a square columnar outer shell supporting the machine body, and a rotating inner drum equipped with multiple components. The inner drum is arranged in a cross shape with grooves that can accommodate four hand-washing components. During washing, the hand-washing components move towards the center of the drum from four directions with the help of an electromagnetic attractor. Normally, an elastic reset plate bounces the hand-washing components back into the grooves. The arms of the hand-washing components are elastic and can wash clothes with different levels of stains, especially suitable for soft silk fabrics and protein-based wool fabrics.

[0005] The rotating inner drum tapers inward at the bottom, forming a smaller cylinder. Inside the cylinder is a hollow axial flow pump with a hollow shaft. A circulating water tank is located outside the shaft. The hollow shaft extends through the outside of the machine. The hollow axial flow pump has three functions: 1. It discharges wastewater from inside the machine through its hollow structure. 2. A spiral groove is engraved on the outer wall of the shaft, and a sealing sleeve is installed to start the motor, drawing water from the circulating tank and spraying it into the drum to agitate and tumble the clothes inside. 3. An electrically controlled dual-function brake engages the hollow shaft to start the motor. The motor housing drives the inner drum to rotate, thus drying the clothes inside.

[0006] The four motors that drive the hand-rubbing components are located on the outer wall of the small cylindrical barrel and are arranged symmetrically in a cross shape with the hand-rubbing components inside the rotating large barrel. The motors are connected to the hand-rubbing components inside the barrel through a transmission flexible shaft.

[0007] The aforementioned electrically controlled dual-function brake is a stationary outer shell connected to a rotating inner cylinder. The electrically controlled dual-function brake is connected outward to four spring supports for adjusting the center of gravity. It is located on the outside of the hollow shaft of the hollow axial flow pump and on the inside of the rotating inner cylinder wall. When open, it is integrated with the rotating inner cylinder, and when closed, it is integrated with the hollow pump shaft. At the moment of opening and closing, it can direct the function of the motor rotor and the stator of the hollow axial flow pump to switch between each other.

[0008] The working principle of the aforementioned two-handed fully automatic washing machine is as follows: Washing Stage: First, press the start button. The program control software controls the following components: open the water inlet valve to fill the machine with water; heating is optional. At this time, the upper and lower electromagnetic suction plates attract each other, driving the hand-washing components to move towards the center of the drum from four directions. The finger clamping plates clamp the clothes. At this time, the four direct drive motors at the bottom of the drum start, driving the four hand-washing components to perform cross-reciprocating motion via flexible shafts. After about 8 seconds, under the control of the software, the four drive motors stop, the upper and lower electromagnetic suction plates separate, and the automatic reset springs bounce the four hand-washing components back into their grooves. At this time, the electronically controlled dual-function brake is in the released state. The hollow axial flow pump and the hollow shaft work together with the motor housing to spray water from the circulation tank directly into the rotating drum. The water column agitates and tumbles the clothes. Under the control of the program control module, the water stops after about 5 seconds, the upper and lower suction plates re-attract each other, and the hand-washing components rub the clothes again, repeating the above working mode. This cycle repeats for about a few minutes, and even heavily stained clothes can be washed clean.

[0009] Bleaching stage: The program control module instructs the electronically controlled drain valve to open, and the sewage is discharged outside the machine through the hollow shaft. Then, it instructs the electronically controlled drain valve to close, instructs the injection of clean water into the machine, and instructs the hollow axial flow pump to continuously spray water into the drum. This process is repeated two or three times to clean the clothes.

[0010] Spin-dry: The program control module commands the electromagnetic drain valve to open, the electronically controlled dual-function brake to tighten the hollow shaft, and the axial flow hollow pump motor to start, driving the inner drum to rotate at high speed. The clothes water isolation sheet isolates the clothes water, and the wastewater is discharged outside the machine through the hollow shaft. At this time, a crisp alarm bell will be heard, and the entire washing process is over. Attached Figure Description

[0013] To make the technical solution of the present invention clearer, the specific implementation method is further described in detail below with reference to the accompanying drawings. First, the working sequence of all components of the present invention is controlled by the program control module 1. First, press the start button to fill the machine with water (the water level gauge is not marked). Whether hot water washing is required is optional. Then, the program control module 1 instructs the electromagnetic suction plates 13 and 14 to engage, which drive the hand-washing components 1, 4, 5, and 6 to move towards the center of the rotating drum 3 and squeeze the clothes through the flexible shaft 9. At the same time, the program controller 1 instructs the finger clamping plates 24 and 25 to clamp the clothes. Simultaneously, the program controller 1 instructs the four direct drive motors 11 to drive the gear set 6 through the flexible shaft 9, which drives the elastic long arm washing component 1 and the elastic short arm washing component 5 to move up and down back and forth, just like a human hand, to rub the clothes for 8-9 seconds. The elastic washing arm components can accurately wash the stains on the clothes of different sizes and softness without causing unnecessary damage to silk and wool fabrics. The above machine operation process is for the clothes After the first 8-9 second wash, the program controller 1 instructs the electromagnetic suction plate to separate. The automatic reset spring 19 then pushes the elastic arm scrubbing attachments 1, 4, 5, and 6 back into the grooves of the rotating inner drum 3. Simultaneously, the program controller 1 instructs the electromagnetic dual-function brake 16 to release the hollow shaft 15 and tighten the rotating inner drum 3. The hollow shaft water pump motor 12 drives the hollow shaft 15 to rotate, drawing water from the circulating water tank 17 into the rotating drum 3 to form a water column, agitating the clothes inside and changing their shape. The program controller 1 then... The hand-washing components 1, 4, 5, and 6 are instructed to move closer to the center of the rotating inner drum 3 to perform a second wave of washing on the clothes inside. Each component repeats the sequence of actions from the first wave of washing. Due to the agitation of the clothes inside the rotating inner drum 3 by the water jets from the hollow shaft water pumps 12 and 15, the clothes change shape. The first wave washes the collar and cuffs of the clothes, while the second wave washes the placket. This process of washing and spraying water changes the shape of the clothes inside the drum, and then washing them again is repeated for about 10 minutes. Even heavy stains on the clothes can be cleaned.

[0014] Second stage rinsing: Program control module 1 instructs the electronically controlled drain switch 16 to open, and the sewage in the drum is discharged outside the machine through the hollow axial flow pump and hollow shaft 15. Program control module 1 instructs the electronically controlled drain switch 16 to close, and at the same time, program control module 1 injects clean water into the machine and instructs the electronically controlled dual-function brake 20 to release the axial flow pump hollow shaft 15 and tighten the rotating inner drum 3. Driven by the hollow axial flow pump motor 12, the hollow shaft 15 is driven to rotate at high speed, continuously rinsing the clothes in the rotating inner drum 3.

[0015] The third stage of spin drying: After the clothes are rinsed clean, the program control module 1 instructs the electronically controlled drain switch 16 to open. The program control module 1 then instructs the electronically controlled dual-function brake 20 to hold the hollow shaft 15 tightly. The hollow axial flow pump motor 12 drives the rotating inner drum 3 to rotate at high speed. The clothes inside the drum are separated from the water by the clothes water isolation plate 23. The sewage is discharged outside the machine through the hollow shaft 15. At this time, the alarm bell 24 can be heard to make a crisp ringing sound. The entire washing process is over.

[0016] The working mode of the two-handed washing machine of this invention is different from that of washing machines currently in use in society. The biggest advantage of this washing machine is that it accurately imitates the human washing method. The arms drive the palms and the fingers hold the clothes and soak them in the washing liquid. The clothes are repeatedly squeezed and rubbed, which forces the washing liquid to shuttle between the fabric threads, effectively removing the stains on the threads. The washing liquid can rub the fabric surface 100 times, but it is not as effective as shuttle between the threads once.
