Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a washing machine in which an agitator disposed inside a J tank is improved.

(Technical Background of the Invention) Conventional J: Washing 2'll 1 As a method, a pulsator is disposed at the inner bottom of the tank [), and the rotation of this pulsator forms a swirling water flow inside the tank. There are well-known devices configured to wash laundry.

[Problems with back M technology]

However, in the above-mentioned conventional washing machine, since washing is carried out using only swirling water, the laundry tends to be strongly twisted, and the washing effect is unsatisfactory, such as uneven washing.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and therefore, its purpose is to provide a washing method that can enhance the washing effect.

[Summary of the invention]

The present invention includes a stirring body disposed inside a tank, a base portion, and a base portion.
It consists of a main part protruding from this base part, and a protrusion part protruding from the approximate center of the base part higher than the wing part, and the tυ111' body is rotated forward and backward 1t for washing. The shape of the instep 1111 of A is eccentric from the center of rotation of the front 1, 11Ua parts, and one of the protrusions is made into a flat shape with <r
T1 stroke (forms this, makes the water flow complicated, and shakes it in addition to running water) and scrubs it with IJ.
I also did 1 wash and 1 + 76 strokes, which covered 41 features.

[Embodiments of the invention]

The present invention will be described below with reference to the drawings, showing an embodiment applicable to a water washing machine. , 1, Zff11 is Jj in the figure, 1 has an outer box, and inside is a bullet ↑ mark 11 holding mechanism 2 (!: through which a water receiving tank 3 is suspended by a bullet f1,

In addition, -1-, ne Irl stirring body 8 is arranged so as to repeat forward rotation and j further rotation, for example, it is rotated 3 times in the forward direction, 1v is reversed, and then it is turned again in the φ direction. It is set to repeat. Now, regarding the structure of shells in 1-1 stirring period 8, as shown in Figures 1 and 2 (,1
2 is the base part, which rotates 1f! It is formed into a culm-like circular shape that extends almost all around the inner bottom of the i7, and four wing parts 13 are protruded from the -1 side of the culm to extend approximately in the shape of a 71. In addition, a protrusion 14 is provided at the central portion of the base al (section 12) to protrude higher than the wing section 13''.A base mold (section 1

Sa-C1 This protrusion 1 /l 1. L. As can be seen from FIG. 2, the 11-sided shape (upper end shape) is shaped like a J-shaped elliptical shape extending from the center of rotation of the base part 12 (the center of the shaft connecting part 15). has been done. And in this case, this 5! The origin 1/l is the longitudinal direction of the groove (left and right direction in Figure 2)
The best distance 11 from the center of rotation of the first part 11a section 12 is set within a range of 1.5 to 2.5 times the shortest distance 12.

Now, the operation of the above configuration will be explained with reference to FIG. now,
Considering the case where the body 8 is rotated, for example, in the direction of the arrow in FIG.
The washing water stored in the interior is generally turned into a swirling water flow by the 9:1 part 14, but in some parts, it is turned into a swirling water flow by the wing part 1/I'', the surface 14a on the rotation direction side of the projection part 14 that protrudes higher. The eddy water flow is made to flow in a centrifugal direction, and a turbulent water flow is formed, resulting in a high tυ1〒 effect on the washing water. on the other hand,
The laundry Δ(
(see Figure 3) is due to the above-mentioned eddy water flow and turbulent water flow.
By 4I water flow? ! 7. As a result, the washed material A itself changes in a complicated manner, causing twisting washing and rubbing washing in the washing itself, thereby increasing the washing effect of washing with water. In particular, when the agitator 8 rotates, the part 14 of the protrusion 5 rotates in the rotating tank 7 as shown by the arrow in FIG. Apply an external force to object A so as to shake it in the centrifugal direction (i.e., shake it) 51. In particular, this cleaning surface i4a also acts to rub the laundry A, that is, causes scrubbing, and furthermore, the protrusion 14 has the longest end 14
At b, it also acts to push the laundry A, that is, pushing washing also occurs. Moreover, after the washed ηr laundry A is shaken off in the centrifugal direction by the protrusion 171, it comes to wrap around the surface 140 of the protrusion 14 in the counter-rotation direction, and as a result, the laundry Δ moves inside the rotating tub 7. It is transferred while rocking from the outside and from the outside to the inside again, that is, the stirring effect on the laundry Δ is great, and overall the cleaning effect on the laundry A can be greatly enhanced and uneven washing can be eliminated. . Also, when the agitator 8 is reversed from forward rotation to reverse rotation, or from reverse rotation to forward rotation, the water flow is reversed with a slight delay in time, but during this transition period, the laundry A is temporarily suspended. The protrusion 14 of the stirring body 8, which is in a stopped state and has already been reversed and is in a rotating state, is -

Effectively promoted and has a total C high cleaning effect! Iru (:
I can do that.

By the way, recent ifr washing machines (13) have a cylindrical protrusion fixed to the central part of lft I'I', but this one (11)
Since only the eddy water current is formed, the laundry items are always flowed towards the protrusion by the eddy water flow, and as a result, the laundry items may wrap around the protrusion, causing the entire laundry to be washed away. There was a problem that there was a problem that there was little replacement of the parts and the cleaning effect was poor, but the Jt also had i'A: frf ml).

According to this embodiment, the planar shape of the protrusion BII 14 is made into an oblate shape that is eccentric from the rotation center of the base part 12.
It is also possible to spread the laundry in the direction of the center of gravity by giving 1 ft of movement in the direction of the laundry, and it is also possible to roughly swing the 3L laundry inward and outward. Therefore, it is possible to make the cleaning effect more human-like, and also to store the laundry items on the 11th floor.

Here, if the degree of eccentricity of the protrusion 1/I is measured η, then the base portion 1 extending in the longitudinal direction J-31-J

This relationship is shown in Figure 4, in which the vertical axis
The horizontal axis shows the degree of eccentricity (1-

The unevenness of the wash is small and the input of the motor is also small.

Therefore, in the longitudinal direction of the protrusion 14,
The longest distance 11-1 from the center of rotation is In-know distance 1111
11-, 2 to 1.5/2.5 times, it is possible to suppress the input to the motor 4 and achieve the effect of reducing uneven washing in the right column.

In the above embodiment, the planar shape of the protrusion 14 is an oval shape, but it can also be formed into a substantially elliptical shape, a substantially horizontally rectangular shape, etc.

[Efficacy of invention]

Kibuto Akira (: It is clear from the i [j statement that i J uniformly,
(The le!l'l' body arranged inside 5Q of a is made up of a base part, a wing part protruding from the base part, and a wing part protruding from the base part higher than the main part at a substantially central part of the base part. The washing machine is constructed of a protrusion that rotates the agitator 4M' body forward and backward to wash the clothes, and the protrusion has a planar shape that corresponds to the rotation of the M vibration section. It is characterized by a flattened shape that is eccentric from the center and is uniformly formed, and this makes the water flow more coarse than the conventional eddying water flow, making it easier to wash with water. Not only can the effect be improved, but also the external force applied to the laundry can be applied to shaking, scrubbing, and pressing the laundry, and the stirring effect can be significantly enhanced, and the replacement of the laundry can be done well, and the overall cleaning effect can be improved. It has excellent effects such as greatly increasing 1q and also reliably eliminating VR unevenness.
