Main Categories Of Modern Washing Machines
Wave wheel washing machine
Wave wheel washing machine: a washing machine in which the washing material is immersed in the washing water and is washed by the continuous rotation or timed forward and reverse rotation of the wave wheel. The wave wheel washing machine mainly drives clothes and water to rotate through the rotation of the wave wheel, relying on the friction between the wave wheel and clothes, clothes and clothes, clothes and bucket walls, water flow to wash clothes, and washing clothes under the action of detergent.
Basic structure of fully automatic wave wheel washing machine
The principle is similar to the scrubbing process of our daily laundry.
Manual scrubbing
Laundry features: microcomputer controlled washing and drying functions, time-saving and labor-saving.
Disadvantages: Power consumption, water consumption, easy entanglement of clothing, poor cleanliness.
Suitable for washing clothes: All clothes except those that require special washing.
Wave wheel washing machines are popular in Japan, China, Southeast Asia, and other places
Washing machines are generally divided into three types based on their washing functions: universal, semi-automatic, and fully automatic.
Popular: A general term for a single drum washing machine without dehydration function. Most of these washing machines are equipped with a timer switch, which can control the intermittent forward and reverse rotation of the wave wheel or drum during the washing and rinsing process, and can automatically stop according to the selected washing and rinsing time.
Semi automatic type: generally double simplified, combining washing machine and dewatering machine into a whole, with washing, rinsing, and dewatering functions, but clothes need to be manually removed and placed in the dewatering machine for dehydration. This type of washing machine is not only equipped with a timer switch for washing and rinsing, but also with a timer switch for dehydration. Currently, double drum washing machines produced in China belong to this type. Compared with the single drum popular type, they only have one more dehydration function, so they are generally referred to as the double drum popular type to distinguish them from the single drum popular type.
Fully automatic type: It is a single barrel type, and washing, rinsing, and dehydration are all carried out in one barrel. In addition to picking and placing clothes, as long as the required work program is followed and the control button position is adjusted, water inlet, washing, rinsing, dehydration, and drainage are all automatically carried out.
Main components of a wave wheel washing machine:
Wave wheel: The wave wheel washing machine mainly relies on the rotation of the wave wheel to stir water and clothes to achieve the purpose of washing. Due to the vortex of the washing solution generated by the wave wheel during high-speed rotation, it is also known as the scroll type.
Washing bucket: The washing process of clothes is carried out inside the washing bucket; Therefore, the washing bucket is also an important component of the washing machine. The combination of the washing bucket and the wave wheel can enhance the vortex and the convex ribs on the laundry wall, which is equivalent to the wiping plate we use in daily life. The friction between the clothes and the bucket wall during rotation can greatly improve the washing effect.
Dehydration bucket: In addition to the washing bucket, there is also a dehydration bucket for double bucket laundry water. Dehydration of clothes is achieved by the high-speed movement of the spin drying basket inside the dehydration bucket. The spin drying basket is mostly made of ABS plastic and also made of enamel, with a rotation speed of about 700-1000 revolutions per minute. The centrifugal force generated causes the clothes to be pressed against the basket wall with water, and the water flies out of the small holes on the basket wall, gradually dehydrating and drying the clothes.
Transmission mechanism: motor, belt and pulley.
Box and support: inner tube frame, shaft, outer tube frame, and rolling bearings. Supporting parts (crossbeam, lifting spring, reinforcing ribs, two fixed damping shock absorbers, outer box body, feet, and rear cover, etc.).
Inlet and drainage system: inlet pipe filter, inlet pipe, inlet solenoid valve, detergent material box, overflow pipe, drainage filter, drainage pump, and drainage pipe.
Control system: There are mechanical and computer controls, both composed of program controllers, water level control relays, water temperature controllers and power switches, energy-saving switches, door safety switches, and other control circuits
Drum washing machine
Drum washing machine: A washing machine in which the washing material is placed in a drum, partially immersed in water, and is washed by continuous or timed forward and reverse rotation of the drum. The outer bucket is filled with water, and the clothes are partially submerged in the water. The inner bucket rotates, and there are protrusions on the inner bucket wall that can drive the clothes to rise. When the clothes reach near the top, due to gravity, they fall to the bottom of the bucket. This repeated beating is similar to the washing method of a manual hammer. To improve the cleaning ability, drum machines generally have a heating and washing function.
Basic structure of drum washing machine
The principle is similar to the process of beating clothes with a hammer.
Laundry features: The microcomputer controls all functions, and the clothes are free from entanglement. The least damaging way to wear clothes
Disadvantages: time-consuming, several times longer than usual, and once the door is closed, it cannot be opened during the laundry process, resulting in weak cleaning power.
Suitable for washing clothes: wool, cashmere, silk, and pure wool fabrics.
Popular in regions such as Europe and South America where wool and cotton are the main clothing, almost 100% of households use drum washing machines.
Stirring washing machine
Simply put, a stirring washing machine is a device that uses a wave wheel to circulate and stir clothes, which emerged before the wave wheel washing machine. The fully automatic stirring washing machine originated in the United States and is popular in the United States, but it is difficult to see it in China. Only domestic manufacturers such as Haier and Rongshida have launched this type of washing machine, and the response is not enthusiastic. Due to the small production volume, the price is relatively high, and the sales are very low. The biggest difference between it and a wave wheel washing machine is that the maximum rotation of the wave wheel is only 270 degrees, unlike the wave wheel of a wave wheel washing machine which rotates 360 degrees.
Basic Structure of Stirring Washing Machine
Structure: Generally composed of inner barrel, outer barrel, stirring wave wheel, motor, and computer controller.
Working principle: The washed object is immersed in the washing solution and is washed by a stirrer installed on the central axis of the washing cylinder, which swings back and forth. The swing amplitude is generally around 120 °~180 °, causing friction between the stirring blade and the clothes, as well as between the clothes. Its bending, stretching, and friction effects are similar to manual rubbing movements.
Laundry features: Clothes have the strongest cleaning power and save laundry detergent. This washing machine has a large washing capacity and is suitable for washing fabrics with fine texture. The washing ratio and wear rate are between the wave wheel type and the drum type.
Disadvantages: Likes to wrap, increases damage compared to the first two methods, and produces the highest level of noise
Suitable for washing clothes: All clothes except those that require special washing. Commonly used in North America.
Comparison of Three Washing Machines
Due to the rotation of the washing wheel, a large ball of clothes in the bucket will inevitably get tangled together, and pulling and pulling between clothes can easily cause fabric damage. Some particularly expensive clothes are not suitable for cleaning with a washing machine. During the rotation process, the force is uneven, and the entire washing machine experiences significant shaking. The advantage is that the operation is simple, it can be stopped and used at any time, and clothes can be added during the laundry process.
The drum, which uses gravity to impact laundry, has much better stability than the wave wheel and is not prone to shaking, making it very suitable for embedded design. It can be directly embedded into the cabinet during decoration, saving space. The disadvantage is that the laundry time is relatively long, and clothes cannot be added midway (some models have added the midway adding function).
