DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a dehydrating and washing machine will be described below with reference to the drawings. First, in FIG. 1, reference numeral 1 denotes an outer box, in which a water tank 3 is elastically suspended via an elastic suspension mechanism 2, and a motor 4 and a mechanism part 5 are mounted on the outer bottom of the water tank 3. A belt transmission mechanism 6 and the like are provided. Further, a rotating tank 7 which serves as a washing machine and a dehydrating tank is disposed inside the water receiving tank 3, and an agitator 8 is disposed at the bottom of the rotating tub 7. The rotating tank 7 is connected to a rotating shaft 9 of the mechanism section 5, and the stirring body 8 is connected to a stirring shaft (not shown) in the mechanism section 5 via a deceleration mechanism 10 disposed at the inner bottom of the rotating tank 7. . Then,
The mechanism section 5 has a clutch mechanism 11,
The clutch mechanism 11 selectively transmits the rotational power of the motor 4 to the stirring shaft and the rotating shaft 9, so that the stirring body 8 is rotated during washing, and the rotating tank 7 and stirring body 8 are rotated integrally during dehydration. It's summery. Further, the stirring body 8 is configured to repeatedly rotate in the forward direction and in the reverse direction, for example, it is set to be rotated three times in the forward direction, then reversed, and then rotated again three times in the reverse direction. Now, to describe the specific structure of the stirring body 8, in FIGS. 1 and 2, 12 is a base part, which is formed in a circular shape large enough to cover almost the entire circumference of the inner bottom of the rotating tank 7. Four wing parts 13 are protruded from the upper surface of the base part 13 in a substantially radial manner, and the base part 12
A protrusion 14 is provided at a central portion thereof to protrude higher than the wing portion 13 . A shaft connecting portion 15 is attached to the upper part of this protrusion 14 so as to coincide with the center of the base portion 12, and the speed reduction mechanism 1 is attached to this shaft connecting portion 15.
0 output shaft 10a (FIG. 1) is connected.
Now, as can be seen from FIG. 2, this protrusion 14 is
The planar shape (upper end shape) is formed to be an oblate shape, for example, an ellipse shape, which is eccentric from the rotation center of the base portion 12 (the center of the shaft connecting portion 15). In this case, this protrusion 14 is
The longest distance L1 from the center of rotation of the base portion 12 in the left-right direction in the figure is set in a range of 1.5 to 2.5 times the shortest distance L2.

れ、総じて高い洗浄効果を得ることができる。 Now, the operation of the above configuration will be explained with reference to FIG. Now, when we consider washing when the agitator 8 is rotated, for example, in the direction of the arrow in FIG. However, in some parts, the rotational direction side surface 14a of the protrusion 14 that protrudes higher than the wing portion 14 causes the eddy water flow to flow in the centrifugal direction, forming a turbulent water flow, resulting in a stirring effect on the washing water. becomes higher. On the other hand, laundry A is stored in the rotating tub 7 together with the washing water (see Fig. 3).
is flowed in a complicated manner by the complicated water flow caused by the above-mentioned swirling water flow and turbulent water flow, and as a result, the laundry A itself changes in a complicated manner and causes twist washing and kneading, thereby reducing the cleaning effect of water washing. becomes higher. In particular, as the protrusion 14 rotates within the rotating tank 7 as shown by the arrow in FIG.
Applying an external force to the laundry A by the whole a so as to shake it in the centrifugal direction, that is, causing shaking washing,
In particular, at this time, the surface 14a also acts to rub the laundry A, that is, causes rubbing, and furthermore, the protrusion 14
also acts to push the laundry A with its longest end 14b, that is, pushing washing also occurs. Moreover, after the laundry A is shaken off in the centrifugal direction by the protrusion 14, the surface 14c of the protrusion 14 in the counter-rotation direction is
As a result, the laundry A is moved in the rotary tub 7 from the inside to the outside and from the outside to the inside again while swinging, which means that the agitation effect on the laundry A is also great, and the laundry is washed in general. The cleaning effect for item A can be greatly enhanced, and uneven washing can be eliminated. Also, when the agitator 8 reverses from forward rotation to reverse rotation or from reverse rotation to forward rotation, the water flow reverses with a slight delay in time, but during the transition period, the laundry A temporarily The protrusion 14 of the agitator 8, which is in a stopped state and has already been reversed and is in a rotating state, acts to squeeze the almost stopped laundry A more reliably and powerfully than when it is flowing. The above-mentioned shaking and scrubbing are extremely effectively promoted, and a high overall cleaning effect can be obtained.

が形成されるため、洗濯物がそのうず水流により
常に突起部に向かつて流動され、この結果該突起
部に洗濯物が巻きつくこともあつて洗濯物全体と
しての入れ替りが少なく、洗浄効果に乏しいと共
に洗濯むらも生じる不具合があつた。 By the way, some recent washing machines have a cylindrical protrusion fixed to the center of the agitator, but with this type of washing machine, only a swirling water flow is formed, so the laundry is washed away by the swirling water flow. The laundry always flows toward the protrusions, and as a result, the laundry may wrap around the protrusions, resulting in less replacement of the laundry as a whole, resulting in poor cleaning effects and uneven washing.

槽７にて内側及び外側に揺動させることもでき、
よつて洗浄効果を大ならしめ得ると共に、洗濯物
の入れ替りも良好に行ない得て洗濯むらもなくし
得る。 In this regard, according to this embodiment, since the planar shape of the protrusion 14 is made into an oblate shape that is eccentric from the center of rotation of the base part 12, it is possible to give the washing water a movement in the centrifugal direction from the center of the base part 12. Moreover, the laundry can be spread out in the centrifugal direction, and the laundry can also be swung inward and outward in the rotating tub 7.
As a result, the cleaning effect can be increased, and the laundry can be changed easily, thereby eliminating uneven washing.

If the ratio L1/L2 between the longest distance L1 and the shortest distance L2 from the center of rotation in 2 is increased, the degree of agitation will increase and uneven washing will become smaller, but the resistance from the washing water will increase. Therefore, the input to the motor 4 becomes large. This relationship is shown in Figure 4, in which the vertical axis shows uneven washing and motor input, and the horizontal axis shows eccentricity (L1/L2).
Line P shows the characteristic of uneven washing, and line Q shows the input characteristic of the motor. As you can see from this figure 4
When L1/L2 is 1.5 to 2.5, uneven washing is small and the motor input is also small.
従つて突起部１４の長手方向における基盤部１

The longest distance L1 from the center of rotation in 2 is 1.5 of the shortest distance L2.
According to this embodiment, which is set to ~2.5 times, it is possible to effectively reduce uneven washing while suppressing the input to the motor 4.
