Description

TECHNICAL FIELD [0001] The present invention relates to an integrated structure of a washing tub and a water-repellent wing, a washing machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine area, and more particularly, to an integrated structure of a washing tub and a water-repellent wing, a washing machine, and a washing method thereof.

Conventional technologies divide the washing machine into a drum washing machine, an impeller washing machine, and a stir bar washing machine. In principle, the impeller washer and stir bar washer are very similar. The impeller washing machine rotates laundry with irregular water by swirling water with water-repellent wings to complete washing and rinsing process of laundry. The stir bar type washing machine borrows the force of the water by the stirring rod directly or indirectly, and rotates the laundry in the water to complete the washing of the laundry. The drum washing machine relies on a myriad of jaws fixed on the inner wall of the washing tub, and the process of washing and rinsing is completed by repeating the process of raising and lowering the laundry by raising the laundry.

Conventional technology is that the drum washing machine uses less water in the washing process, less damage to the fabric, it can set the hot water device without tangling the laundry and easily realize the automation, but the washing power is weak, the washing time is long, the structure is complicated, It is large, consumes large amount of metal raw material, and costs are high. And it is relatively difficult to control the equilibrium when dewatering by velocity. Stirrer-type washing machines can evenly wash, have strong washing power, have less damage to cloth, and have a large washing amount. However, the washing time is long, the noise is large, and the rotating structure of the water repellent wing is complicated, so that the processing is difficult, the cost is high, and the volume is also large. The impeller washing machine has a simple structure, strong washing ability, short washing time, low cost and light weight. However, the rate of damage and tangling of the fabric is high, and it can not be washed evenly, and water is used a lot.

Currently, washing machines are widely used in homes, but most of them are double-motor or double washing machine washing machines. In order to install water repellent blades in a washing machine of a general impeller washing machine, the structure is relatively complicated, installation work is troublesome, and the cost is high. If the washing machine and the water repellent structure are manufactured in an integrated structure, the difficulty of the installation work and the cost will be drastically reduced. So, it is a big problem for us to connect the advantages of the above-mentioned washing machines in some way.

Patent No. CN200510094191.3 disclosed a washing method which is excellent in washing power, low in cost, and free from environmental pollution. It includes the following procedures. First, put an appropriate amount of detergent and defoamer in a washing machine containing laundry. Second, the controller controls the rotation speed of the washing tub to be between 3 rpm and 12 rpm, alternately rotating the washing machine in the forward and reverse directions, rotating the washing machine 0.3 to 1.5 times, and reversing the washing machine 0.3 to 1.5 degrees. This rotation is continued for 0.4 to 1.5 minutes and then stopped for 0.3 to 1.5 minutes. Third, repeat the above second procedure 3 ~ 20 times. Fourth, the washing machine is rotated in one direction and the course is distributed evenly. After completion of the course, dehydration proceeds for 0.3 to 3.5 minutes. Fifth, the process from the first to the fourth is repeated 2 to 12 times, thereby completing one washing process. However, in the case of a drum washing machine, there is still a problem that it is difficult to control the equilibrium maintenance when dehydration is performed at a high speed.

In the Chinese patent with patent number CN03276136.8, we unveiled a washer that removes the time well and reduces the tangling and damage. This spiral washing machine not only improved cleaning power, but also washes evenly and lowered laundry tangling and damage. However, the structure of the washing machine is simple, the bottom of the washing machine is integrally connected to the inner wall, there is no clutch, and the inner wall of the washing machine is composed of a helical pattern in a double line shape. This washing machine cleans the laundry through a comprehensive action such as rubbing in the angular direction, centrifugal cleaning without side effects, cavitation, and inertia operated at high speed through pressure during the course of running, stopping, and reversing. However, the washing machine mentioned in the aforementioned patent has added a spiral structure to the inner wall of the washing tub, and the structure of the bottom of the washing tub is not defined, and the space of the bottom of the washing tub is wasted.

Patent No. CN00215731.4 discloses a fully automatic washing machine without a water-repellent wing, which includes a washing tub, an outer tube, a water-repellent rubber and a motor. The feature is that the water-repellent rubber of the washing tub and the bottom of the washing tub are integrally connected and replaced the water-repellent wing of the conventional impeller washing machine with the water-repellent rubber on the bottom of the washing tub. The rotor of the motor is fixed to the main shaft of the washing machine, and the rotor of the motor and the washing machine cooperate with the main shaft of the washing machine. Since the washing machine and the water-repellent rubber on the bottom of the washing machine are integrally connected, the water-repellent rubber on the bottom of the washing machine acts as a water-repellent wing when the motor leads the rotation of the washing machine in the normal direction and the reverse direction. The above-mentioned patent does not disclose the structure of the water-repellent wing, and the structure of the bottom of the washing machine and its side surface is not described. As shown in the drawing, the structure of the bottom of the washing machine did not cause any additional action to the rotation of the laundry, and the side has no corresponding water repellent wings to stir the water in the washing tub.

The present invention has been made in view of the above.

It is an object of the present invention to overcome the drawbacks of the prior art and to provide an integrated structure of a new type of washing tub and water repellent wing and to add a water repellent structure to the bottom of the washing tub. This structure extends from the bottom of the washing tub to the inner wall of the washing tub, thereby not only repeating the process of raising and lowering the laundry in the circumferential direction, but also washing the laundry so as to be cleaned as a whole. Therefore, the laundry can complete the washing, rinsing and dehydrating process by using only one washing machine, and the structure of the washing machine is simple, not only the difficulty of the installation work is reduced, but also the cost is reduced.

Another object of the present invention is to disclose a washing machine having an integrated structure of the washing tub and the water-repellent blades.

Still another object of the present invention is to disclose the washing method of the washing machine described above. This washing method reduces the tangling of the laundry by using the time difference progression between the forward running and the backward running and prevents the cloth from being washed at the same position, The method of increasing the strength to rise during washing, the centrifugal rotation, tapping, rubbing due to friction, etc.

In order to realize this object, the present invention applies the following technology.

It is an integrated structure of a washing tub and a water-repellent wing, which includes a vertical washing tub and a water-repellent wing on the bottom of the washing tub. The water repellent wings and the bottom of the washing tub are integrally provided. The water repellent wings are two or more convex structures provided on the bottom of the washing tub, and each water repellent wing extends from the center of the washing tub to the inner wall of the washing tub. Each water-repellent wing extends from the bottom of the washing tub to the highest point in the radial direction and is connected to the inner wall of the washing tub. It extends from one side along the circumference to a gentle slope peak, then descends to the bottom of the washing machine with a steep slope.

The number of the water repellent blades is 2 to 4 and the number of the water repellent blades is uniformly distributed in the radial direction from the bottom of the washing tub in the clockwise direction or the opposite direction of the circumference of the washing tub, .

The gently rising slope of the water-repellent wing is smoothly raised, the steep falling slope of the water-repellent wing is smoothly lowered, and the bottom of the washing machine, the gentle rising slope, and the steep falling slope smoothly follow. The above water-repellent wing smoothly goes outward in the radial direction from the bottom of the washing machine, and the inner wall of the washing machine and the water-repellent wing smoothly extend.

The water-repellent blades form a ridge at the highest point in the radial direction of the washing tub, and the ridge is formed of two curved lines. The centrifuges of the bifurcated curves are distributed on the other side of each ridge. The center of the curve near the center of the washing tub is on a gentle ascending slope, and the center of the curve located on the inner wall of the washing tub is on a steep descending slope.

Mentioned water repellent blades are different in the inclination at both sides of arbitrary points of the ridge and the inclination of the gentle ascending slope is smaller than the inclination of the steep descending slope.

The intersection line of the water repellent wing and the bottom of the washing machine has a curved line, and the intersection of the gently rising slope and the bottom of the washing machine bottom is steeply inclined with respect to the inclined plane of the descending slope and the bottom of the washing machine.

The ratio of the height of the washing tub to the diameter of the washing tub is 0.4 to 2, and the height of the optimum washing tub is equal to or smaller than the diameter of the washing tub.

The ratio of the height of the washing tub to the diameter of the washing tub is 0.6.

In the center of the washing tub described above, there is provided a shaft hole in which a power shaft can be inserted, and a plurality of leakage holes are distributed in the inner wall of the washing tub or in the bottom of the washing tub.

The above-described integrated structure of the washing machine and the water-repellent blades is integrated into the washing machine, and the power shaft of the washing machine is inserted into the yoke of the sole located at the center of the bottom of the washing machine having the integrated structure of the washing tub and the water-

As a kind of washing method, this method controls the time interval between the normal running and the reverse running of the washing machine so that the laundry is rotated in the washing tub and completed washing. In this method, the angle of the normal running of the washing machine is different every time, the angle of the backward running is different each time, and the angle of the regular running is different from the angle of the backward running. By the integrated structure of the washing tub and the water-repellent wing, when the laundry is placed in the circumferential direction, the laundry is pulled up and almost vertically dropped, and when the laundry is run in reverse, the laundry collides with the vertical surface in the circumferential direction. The centrifugal force formed in the radial direction and the structure of the bottom of the washing machine cause the laundry to be rotated to the outside and the upper side and to be rotated inward and downward against the inner wall of the washing machine.

The above laundry is pulled up when it is placed in the circumferential direction, then dropped, collided when it reverses, and at the same time, the rotation in the radial direction is progressing simultaneously, so that the laundry is continuously rotated continuously in the washing tub, It is washed evenly.

The above-described rotational movement of the laundry in the circumferential direction and the radial direction is due to the convex structure of the washing tub.

At least two convex structures and two or four convex structures are optimum, and the convex structures are distributed around the central axis of the washing tub according to the clockwise or counterclockwise direction of the bottom of the washing tub. As shown in Fig. This convex structure extends outwardly in the radial direction from the bottom of the washing machine and extends to the highest point and is connected to the inner wall of the washing tub. As the circumferential direction increases from one side to the gentle slope, it extends to the highest point and then descends to the bottom of the washing machine with a steep slope.

In the circumferential direction during the washing process, the laundry gradually rises up to the peak along the convex structure, then falls along a steep slope close to the vertical, and when it is reversed, the laundry hits the steep slope near the vertical.

In the radial direction of the washing tub during the washing process, the laundry is rotated outwardly and upwardly along the convex structure due to the centrifugal force formed by the rotation, and the tub is rotated inward and downward against the inner wall of the washing tub.

During the washing or rinsing of the washing method, the washing tub rises to the constant traveling speed X according to a constant acceleration, rotates for a predetermined time T1, stops for a while, and then rises to the reverse traveling speed Y according to a constant acceleration. Rotate. Each time the angle is different from the backward angle, the above-described procedure is repeated 5 to 500 times for washing or rinsing each time.

The normal running speed X and the reverse running speed Y are 20 to 100 rpm, respectively, and the normal running time T1 and the inverse running time T2 are 1 to 5 s and XxT1YxT2, respectively.

The above-described washing method includes the following procedures.

1) Put the detergent and laundry into the washing machine and operate the washing machine.

2) In order to control the washing machine, the fixed traveling speed is raised to X at a constant acceleration, and the rotation is continued for a certain time T1 and then stopped temporarily. Then, the reverse traveling speed is increased to Y at a constant acceleration and rotated for a predetermined time T2. Each time the angle of the forward run is different from the angle of the backward run, repeat this process 5 to 500 times.

3) When entering the dehydration stage: After the laundry is uniformly distributed by controlling the forward running and reverse running of the washing tub, the washing tub is rotated at a very high speed to proceed dehydration.

4) If you wash more times, add more detergent and repeat steps 2) and 3).

5) Control the water supply to the washing machine and repeat steps 2) and 3) 1 ~ 8 times.

The present invention has the following beneficial effects by applying the above-described technology.

3. In the present invention, the water-repellent blade of the bottom of the washing machine gradually rises along the circumferential direction and then descends rapidly, thereby pulling up and dropping the laundry when putting it down to see the effect of tapping, . The laundry is gradually raised in the direction of the inner wall of the washing tub from the center of the washing tub, then connected to the inner wall of the washing tub at the highest point, and the laundry is rotated upward and outward in the radial direction and is rotated downward and inward by being hit against the inner wall of the washing tub.

FIG. 1 shows an integrated structure of a washing tub and a water-repellent bladder according to the present invention, and includes a washing tub 1 used vertically and a water repellent bladder 2 of a washing tub bottom 11. The water repellent blade 2 and the washing tub 1 are provided in the same body. The water repellent blades 2 should have at least two water repellent blades as convex structures of the washing tub bottom 11 and each water repellent blades 2 are arranged in the circumferential direction of the washing tub bottom 11 and outwardly along the radial direction of the washing tub Extends up to the highest point outward along the radial direction of the washing tub bottom 11 and is connected to the inner tub 12 of the washing tub. Then, along the circumferential direction, it extends upward along a gentle upward slope toward one side, and then connects to the bottom of the washing machine along a steep descending slope at the highest point.

That is, the water-repelling blades 2 extend from the center of the washing tub bottom 11 to the inner tub 12 of the washing tub 11 and the water-repellent blades 2 of the washing tub bottom 11 rise gradually to the highest point in the circumferential direction, And gradually rises in the direction of the inner wall 12 of the washing tub from the center of the washing tub 1 to be connected to the inner tub 12 at the highest point.

When the laundry is placed in the circumferential direction during the washing process, the laundry is raised by the water-repelling blades 2 to a highest point along the gradually rising slope 22 and dropped along the steep descending slope 22 near the vertical, Receive. The laundry is hit by a steep descending slope 22, which is close to vertical, and is subjected to an impact force. The centrifugal force generated by the rotation in the radial direction of the washing tub and the water repellent blades 2 on the bottom 11 of the washing tub gradually rise from the center of the washing tub to the inner wall of the washing tub so that the laundry rotates outward and upward along the water- Bumps into the inner wall 12 and then rotates inward and downward. When the washing machine is rotated in the circumferential direction, when it is pulled up or downwardly, it collides with the rotation in the radial direction, so that the laundry keeps rotating continuously in the washing tub. It rubs against the bottom and inner wall of the washing machine, Are washed.

Rotation in the direction in which the washing tub 1 is lifted is referred to as an inverse running, and in the opposite case, it is defined as a constant running.

The number of the water repellent blades 2 is 2 to 4 and the number of the water repellent blades 2 is distributed around the central axis of the washing tub bottom 11 and rises along the clockwise or counterclockwise direction of the circumference of the washing tub bottom 11 . When the number of the water repellent blades 2 is two, the two water repellent blades 2 should be symmetrically distributed. When there are three water repellent blades, the angle between any two water repellent blades should be 120 degrees. When the number of the water repellent blades 2 is plural, the water repellent wings should be distributed uniformly in a radial shape surrounding the central axis of the washing tub 1.

When the water repellent blade 2 is raised or extended in a clockwise or counterclockwise direction in the circumferential direction of the washing tub bottom 11, the water repellent blade 2 gradually extends from low to high, and the water repellent vane 2 is moved outward along the radial direction of the washing tub When extended, the width is gradually increased from low to high, the width between both sides extending from low to high is gradually widened, and the width of the inner wall 12 is the widest.

The gently rising slope 21 of the water repellent vane 2 gradually increases and the steep falling slope 22 of the water repellent vane 2 is gradually lowered. The water level of the water repellent blade 2 is gradually increased along the radial direction of the washing tub bottom 11 and the washing tub bottom wall 11 and the washing tub inner wall 12 are smoothly connected to each other. The water repellent blade 2 is smoothly connected.

The water-repellent blades 2 form the ridge 23 of the water-repelling blades at different positions in the radial direction of the washing tub 1, and the main shaft 23 is formed of a bifurcated curve. The centrifugal of the bifurcated curve is distributed on the other side of the ridge 23. The center of the curve located near the axis of the washing tub is located on the gentle ascending slope 21 and the center of the curve located near the inner wall of the washing tub is located on the steep descending slope 22). The bifurcated curve is smoothly connected, and the shape of the water-repellent blade (2) is similar to that of "~" when viewed from above the washing tub (1).

When the water-repellent blade 2 is inclined such that the cylindrical surface of the cylindrical column, such as the washing tub 1 in which the arbitrary point on the ridge 23 is located, is different in inclination from both sides of the point of inclination and the inclination of the gently rising slope 21 is steep Is lower than the inclination of the descending slope (22).

The intersection of the water repellent vane 2 and the washing tub bottom 11 is a curved line and the intersection a between the gently rising slope 21 and the washing tub bottom 11 and the intersection of the steep descending slope 22 and the washing tub bottom 11 b are the same but have different bending radii. The radius of the line of intersection (a) between the gently rising slope 21 and the bottom of the washing tub 11 is smaller than the radius of the line of intersection b between the steep falling slope 22 and the bottom of the washing tub 11, The outer periphery smoothly extends. Such a structure can not avoid widening the width of both sides in a direction extending from low to high, and the width of the inner wall 12 of the washing tub is the largest.

The ratio of the height of the washing tub 1 to the diameter of the washing tub 1 is in the range of 0.4 to 2. The height of the optimum washing tub is smaller than or equal to the diameter of the washing tub 1 and the height of the washing portion inside the washing tub is smaller than the minimum diameter , And the case where the ratio of the height and diameter of the washing tub is 0.6 is the case of optimization. The water-repellent wings thus sufficiently utilized the impact force applied to the laundry and the centrifugal force.

Reinforced rubber strips 3 for reducing the deformation of the washing tub 1 are provided on the inner wall 12 of the washing tub 1 or on the washing tub bottom 11. [ The reinforcing rubber band 3 is provided on the outer surface of the inner wall 12 of the washing tub 1 along the direction of the axis or in the circumferential direction and is arranged on the outer surface of the washing tub bottom 11 of the washing tub 1, It is installed on the outer surface.

The reinforcing rubber strips 3 on the outer surface of the washing tub inner wall 12 may be installed along the direction of the axis on the outer surface of the inner wall 12 of the washing tub 12 or horizontally along the circumferential direction, have. The reinforced rubber strip provided on the outer surface of the washing tub bottom 11 is installed on the outer surface of the washing tub bottom 11 in the circumferential direction or in the axial direction or in the circumferential direction and the axial direction. Therefore, the strength of the washing tub 1 is greatly enhanced.

A shaft hole 4 (see FIG. 4) for inserting a power shaft is provided at a center position of the washing tub bottom 11, and a power shaft is inserted into the shaft hole 4 to guide the rotation of the washing tub to complete the washing process. Numerous water leakage holes 5 are distributed on the inner wall 12 of the washing tub 1 or on the bottom 11 of the washing tub 1 to help exchange water inside and outside during washing and draining.

In the present invention, a kind of washing method is described. In this method, the time interval between the normal traveling and the reverse traveling of the washing machine is controlled, whereby the laundry is rotated in the washing tub and completed. In this method, the angle of the forward running of the washing machine is different each time, the angle of the backward running is different each time, and the angle of the regular running is different from the angle of the backward running. By the integrated structure of the washing tub and the water-repellent blades, when the laundry is placed in the circumferential direction, the laundry is pulled up and almost vertically dropped, and when the laundry is reversed, the laundry collides with the vertical surface in the circumferential direction. The centrifugal force formed in the radial direction and the structure of the bottom of the washing machine cause the laundry to be rotated to the outside and the upper side and to be rotated inward and downward against the inner wall of the washing machine.

The above laundry is pulled up when it is placed in the circumferential direction, then dropped, collided when it reverses, and at the same time, the rotation in the radial direction is progressing simultaneously, so that the laundry is continuously rotated continuously in the washing tub, And the washing power is increased. The above-described rotational movement of the laundry in the circumferential direction and the radial direction is due to the convex structure of the washing tub. In the circumferential direction, when the laundry is placed in the circumferential direction, the laundry gradually rises up to the highest point along the convex structure and then falls along a steep slope close to the vertical. When the laundry is reversed, the laundry hits the steep slope near the vertical. During the washing process, the laundry is rotated to the outside and the upper side along the convex structure due to the centrifugal force formed while rotating in the radial direction of the washing tub, so that the laundry is rotated inward and downward against the inner wall of the washing tub.

During the washing or rinsing of the washing method, the washing tub rises to the constant traveling speed X according to a constant acceleration, rotates for a predetermined time T1, stops for a while, and then rises to the reverse traveling speed Y according to a constant acceleration. Rotate. Each time the angle is changed from the inverse direction, the above procedure is repeated 5 to 500 times. Each time the angle of the forward running is larger or smaller than the angle of inversion.

The normal running speed X and the reverse running speed Y are 20 to 100 rpm, respectively. The normal running time T1 and the inverse running time T2 are 1 to 5 s, and XxT1YxT2, XxT1 > YxT2 or XxT1 <

The above-described washing method includes the following procedures.

1) Put the detergent and laundry into the washing machine and operate the washing machine.

2) In order to control the washing tub, the fixed travel speed is increased to X at a constant acceleration, and the rotation is continued for a certain time T1. After a short stop, the reverse rotation speed is increased to Y at a constant acceleration and rotated for a predetermined time T2. Each time the angle of the forward run is different from the angle of the backward run, repeat this process 5 to 500 times.

3) After entering the dehydration step: the laundry is uniformly distributed by controlling the forward running and reverse running of the washing tub, and then the washing tub is rotated at a very high speed to proceed dehydration.

4) If you wash more than one time, you should add more detergent.

5) Control the water supply to the washing machine and repeat steps 2) and 3) 1 ~ 8 times.

A washing machine applying a kind of the above-described washing method is disclosed. This washing machine has various trajectory of the laundry, pulls up the laundry, drops it down, and causes the laundry to be thoroughly washed uniformly under the action of centrifugal rotation, bump, friction, rubbing and the like. The laundry is simultaneously washed in the circumferential direction and the radial direction, so that the laundry is evenly washed and the cleaning effect is excellent.
