Description

A kind of suspended double pulsator turning and kneading laundry method

technical field

The invention relates to a washing method, in particular to a hanging double wave wheel turning and kneading washing method.

Background technique

In the prior art, fully automatic washing machines can be roughly divided into two types, one is a top-opening vertical axis pulsator washing machine, and the other is a drum washing machine.

The pulsator washing machine relies on the pulsator at the bottom of the inner tub to turn the water flow forward and reverse to drive the clothes to turn over and wash. There is also a "hand rubbing" washing technology that rotates the inner tub while the pulsator is reversing. The pulsator of the existing pulsator washing machine can only turn the clothes in forward and reverse directions, and entanglement is likely to occur after a large amount of clothes are washed or washed for a long time. Since the pulsator washing machine relies on the water flow to drive the clothes to be turned over for washing, the water consumption is large during washing, and the water must be injected into 3/5 to 4/5 of the height of the washing bucket (outer bucket). For example, a pulsator with a capacity of 60 liters Washing machine with a water capacity of 53 liters for the high water level and 43 liters for the low water level.

The drum washing machine is driven by a rotating drum soaked in detergent to turn over the laundry loaded in the drum to achieve the purpose of washing the clothes. As long as the laundry can enter the washing water, it can be washed, so the drum washing machine saves water, but the drum washing machine with the front opening door is generally inconvenient to use; although the drum washing machine with the top opening door is easy to use, the structure is complicated and expensive. The high-end drum washing machine can only roll in one direction around the drum shaft, and the washing effect of the clothes wrapped in the center is poor; the wave-wheel washing machine is popular in the market for its clean washing and easy use.

It is one of the long-term goals of the washing machine industry to provide a washing method for a washing machine that has the advantages of high cleaning rate, convenient use, low price, and water-saving and time-saving advantages of a drum washing machine.

Detailed ways

Figure 1 is a flow chart of the method of the present invention. The invention provides a suspended double pulsator turning and kneading laundry method. During the washing process, a pair of rotating pulsators with at least one convex rib are used to turn, knead and squeeze the laundry to be washed. Squeeze out the stains in the laundry fibers, such turning and squeezing can improve the washing effect. The laundry method also includes: water intake, soaking (optional), washing, draining, rinsing, dehydration and other steps.

Step 1. According to the amount of laundry and the type of laundry, the system automatically controls the water intake to the set water level; the system automatically controls the water level according to the amount of laundry and the type of laundry, including fuzzy set water level and Set the water level by weighing method. Both of these two water level control methods are known technologies and will not be described in detail here.

The water level controlled is much lower than that of ordinary pulsator washing machines. Generally, the height of the washing liquid is the height of just soaking the clothes. When the water is in, the inner bucket runs at a low speed, and the pulsator rotates intermittently, driving the clothes to turn over so that they can be better soaked in water. . Therefore, under the condition of the same amount of laundry, a higher concentration of washing liquid can be obtained under the condition that the amount of detergent used is less than that of the ordinary automatic top-loading washing machine, which is beneficial to the removal of stains and reduces the washing time.

Step 2: Wash the inner tub without turning, use a pair of pulsators with convex ribs that are opposite to each other at an acute angle to rotate in the same direction, and the convex ribs on the two pulsators are set opposite to each other with a difference of 180 degrees, and use the convex ribs to drive the laundry to turn over and knead Wash for several minutes; the acute angle between the two pulsators is 60°. The laundry is first turned over by the ribs of one of the pulsators, because the ridges of the pulsator on one side mainly drive the laundry to move , so when the laundry is turned forward, it also has the effect of turning the other pulsator sideways. After rotating 180 degrees, the ribs of the other pulsator will drive the laundry to turn forward, and there is also a sideways Another role of the pulsator is to turn over, so that the clothes are turned and washed alternately forward and backward. After a certain period of time, the washing is completed, and after dehydration, it enters the rinsing step.

Step 3: Rinse the water to the water level automatically set in step 1, the pulsator rotates, and the clothes are repeatedly immersed in water for rinsing. This rinsing method belongs to water-saving rinsing, and the water used is generally only one-third of the height of the pulsator.

Step 4: After dehydration and drainage, the inner barrel rotates from low speed to high speed for dehydration.

Step five, repeat steps three, four one to two times.

The hanging type double pulsator turning and kneading laundry method of the present invention can also be that the convex ribs on the two pulsators are arranged at the same height relative to each other. As a result of such setting, the laundry is only tumbling forward and lacks sideways tumbling, which is different from the existing ones. Drum washing machines are similar.

In the hanging type double pulsator turning and kneading laundry method of the present invention, a soaking step can also be set before washing after water intake.

The soaking is soaking in a high-concentration washing solution for several minutes. Due to the suspension type double pulsator turning and kneading laundry method of the present invention, as long as the washing solution can soak into the laundry, it can be washed, so the concentration of the washing solution is relatively high. High, good for stain removal, less soaking time.

The above rinsing step can also be set to consist of two steps of low water level rinsing and high water level rinsing. in:

Low water level rinsing is to add water to the height set by the washing machine in step 1 to saturate the clothes, make the pulsator rotate, and use the convex ribs to drive the laundry to be turned over and rinsed for several minutes; through turning and squeezing, the dirty water and Stains drain.

High water level rinsing is to add water to a higher rinsing water level. The higher water level means that the height of the water level exceeds the height of the clothes by at least 30mm, so that the pulsator rotates to generate a vertically rotating and tumbling water flow to rinse the clothes.

The above-mentioned rinsing step can also only use high water level rinsing instead of low water level rinsing.

In the second high-water level rinse, a variety of different rinsing and rotating water flows can be obtained by setting different rotation combinations of the inner barrel and the pulsator: including:

Rotate the inner tub to generate horizontally rotating and tumbling water flow to rinse the clothes;

The pulsator and the inner tub are rotated at the same time to generate obliquely rotating and tumbling water currents to rinse the clothes.

Make the pulsator and the inner barrel rotate at intervals to generate rotating and tumbling water flow to rinse the clothes, and the washing is completed by repeatedly immersing the laundry in water.

Shown in Fig. 2 is the used turning and kneading pulsator washing machine of the present invention's suspended double pulsator turning and kneading laundry method, described turning and kneading pulsator washing machine, comprising inner tub 1, outer tub 2, pulsator 3 and transmission device 4, Wherein, there are two pulsators 3, which are relatively pivotally arranged below the side of the inner tub. This is the biggest difference from the existing pulsator washing machine, because it is possible to realize the tumbling and washing of the laundry due to the adoption of two oppositely arranged pulsators. The two pulsators are disk-shaped, and are pivotally arranged under the side of the inner tub 1 at a certain angle. In order to prevent the clothes from being caught between the pulsator and the inner tub, the bottom of the inner tub 1 is designed to be The spherical shape makes the gap between the disc-shaped pulsator 3 and the inner bucket 1 smaller, so as to ensure that the clothes are not pinched. The bucket bottom of the outer bucket 2 is also correspondingly spherical, and another effect brought by such a design is water saving.

Figure 3 is a three-dimensional schematic view of the pulsator used in the hanging double pulsator method of turning and kneading laundry according to the present invention. As can be seen from the figure, the pulsator 3 is in the shape of a concave spherical crown. The convex rib 6 formed by the water front 7 and the rear slope surface 8, the rib of the convex rib 6 is roughly parallel to the diameter of the wave wheel and tangent to the central mounting column 5, and the convex rib 6 is roughly connected to the central mounting column 5 of the concave spherical crown surface. Going to the edge with the involute line, in the process of washing and rinsing, add water to the water level just before submerging the clothes, and in high-concentration detergent, use the above-mentioned pair of pulsators set opposite to each other at an acute angle to rotate in the same direction to drive.

The above are only specific embodiments of the present invention, and those who are familiar with the art can easily make various modifications or changes accordingly. Therefore, all equivalent replacements that do not depart from the spirit of the claims of the present invention should include within the scope of protection of this patent.
