The present invention relates to a washing machine which is composed of a body and a container-shaped stirring body disposed below the inside of the body, and mainly performs cleaning by frictional contact between each peripheral part of the body and the laundry.

In the conventional washing machine, the rotary blade type which generates water flow by the rotary blades and performs the washing action is required to flow the laundry into the water stream, so a large washing tank volume is required according to the amount of laundry, which can be washed at a time. It means that the amount is small.

In addition, when the amount of laundry is small, the water flow becomes extremely strong, resulting in an over-cleaning shape, and when the amount of laundry increases, the water flow rate decreases and the cleaning effect tends to decrease rapidly. In addition, since the contact between the laundry and the rotary wing is accidental and only partially in contact, the effect of rubbing on the entire laundry cannot be expected, so-called laundry stains are likely to occur, and the laundry is easily damaged.

On the other hand, recently, it is a new way to remove the rotor blade, it is proposed to obtain the washing action by the speed difference between the water and the laundry by rotating the washing tank intermittently with the water and the laundry contained, this is the laundry There is an advantage of not being damaged, but the speed difference between the laundry and water is small and has a disadvantage of low cleaning effect due to a simple operation.

The object of the present invention is to prevent the strong and stain-free cleaning effect and the damage of the laundry more than conventional, without the conventional rotating blade or the rotation of the entire washing tank, while at the same time can maintain a large amount of washing and a proper cleaning effect at once An object of the present invention is to provide a washing machine with a wide range of laundry.

The present invention arranges a container-shaped stirring body in the lower part of the tank, accommodates the laundry with water in the tank, and allows the laundry to flow by the water flow and the contact friction generated by the container-stirring body. Washing is performed by synergy with the frictional force received from the upper circumferential wall of the tank to form a projection projecting upward in the center of the bottom of the container-shaped stirring body, and to drive the container-shaped stirring body from below. By fitting the shafts, the upper and lower sides of the laundry can be further completed, thereby improving the washing effect.

Hereinafter, a first embodiment in which the present invention is applied to a combined washing machine for dehydration will be described with reference to FIGS. 1 and 2.

(1) is an outer box, and the drip tank (2) is provided inside, and it is elastically supported by rocking material by opening the zip rod mechanism (3). (4) is a washing tank. In this embodiment, it is comprised by the combination of the tank 5 which rotates at the time of dehydration operation, and stops at the time of washing, and the stirring container 6 with a shallow bottom. This is described in detail below. The tank 5 is arranged in the drip tank 2 to connect the outer bottom part to the hollow dewatering shaft 7, and the container-shaped stirring body 6 is disposed below the inner circumferential wall surface of the fixing tank 5. do. At this time, in particular, the container-shaped stirring body 6 is formed in a tapered shape in which the circumferential wall height is approximately half the height of the tank 5, that is, the depth, and the inner and outer sides are gradually increased in size from the lower part to the upper part. In addition, the inner surface thereof is formed on the concave-convex t-1 by a plurality of grooves 8 extending in the vertical direction, respectively. (9) forms a recessed part (t-2) (10) (11) in the protrusion part which protrudes upward in the bottom center of the container-shaped stirring body 6, respectively at the outer bottom side and the upper end side, and the recessed part 10 The hole 12 which communicates the 11 is formed. The recessed part 10 is fitted to the washing shaft 13 and fixed to the washing shaft 13 by a screw 14, whereby the container-shaped stirring body 6 is connected to the washing side 13. do. On the other hand, in this embodiment, the washing tank 4 is configured to serve as a dehydration tank, thereby forming a dehydration hole 15 in the circumferential wall of the shell 5. Numeral 16 is a power control mechanism, which transmits the rotational force of the washing machine motor 17 to the washing shaft 13 when the washing machine decelerates, and alternately reverses the washing power, and dehydration shaft 7 and the washing shaft 13 when dewatering. (18) is a drain valve and water in the washing tank (4) in order to rotate the tank (5) integrally with the vessel-shaped agitator (6). It is configured to discharge to the outside from the bottom of the drip tank (2) via a drain hose (19). 20 is a timer and is configured to automatically control the temporary stroke from washing to final dewatering.

In the above structure, in the washing operation, the tank 5 is exposed upward from the circumferential wall of the container-stirred body 6 by restraining the tank 5 by rotating the container-shaped stirring body 6 by restraining it by the brake mechanism. The main wall part of the washing tank 4 functions as a fixed main part in the main wall of the washing tub 4, and the main wall of the container-stirred body 6 functions as a movable main wall part.

Next, the operation of the above configuration will be described. At the time of washing | cleaning, water is supplied to the drip tray 2 and therefore washing tank 4 like water washing | cleaning quantity similar to a normal washing machine, and a laundry is input. And the washing operation is settled only the container-shaped stirring body 6 in the state constrained by the brake mechanism so that the tank 5 may not rotate. Reverse rotation drive.

In this embodiment, the rotational speed of the container-shaped stirring body 6 is within the range of 120 to 180 revolutions per minute, and the rotation direction is reversed approximately every 2 to 3 revolutions.

By the way, in this washing operation, the laundry contacts the circumferential wall of the container-stirred body 6 and the circumferential wall of the tank 5, so that the lower part of the laundry is contacted by frictional contact with this from the stirrer 6. As shown by the middle arrow X, rotational force is applied, and on the upper side, it is restrained by frictional contact with the tank 5 and simultaneously receives frictional force in the other direction, thereby imparting a twisting action or pressing action to the laundry. The laundry is repeatedly pressed in the direction of the circumferential wall of the washing tank 4 by the centrifugal force caused by the rotation of the container-stirring body 6 while being repeatedly performed by reversal of the rotational direction of the container-stirring body 6. By receiving inward from the circumferential wall of (5), as shown in the direction of arrow Y in the figure, the inverting action also occurs. It made easy. In particular, in the present embodiment, since the container-shaped stirring body 6 is formed into a tapered shape that gradually increases from the bottom to the upper part, the laundry is smoothly operated by the centrifugal force, and the water is also smoothly operated so that the rising is easy and Since the protrusion 9 is formed at the center of the bottom of the gas phase agitator 6, the flowing water flows smoothly to the outside from the center bottom of the container agitator 6 and outwards. This is facilitated. Therefore, the laundry is rubbed by the large friction between the laundry and the large friction between the main body 5 and the circumferential wall of the container agitator 6 by the above complicated operation, while washing is a kind of twisting or repeated pressure The washing effect is excellent because all of the laundry evenly washes uniformly on all the laundry. The cleaning effect is the same as that shown in FIG. 2 as an example of the experimental results. In FIG. In the case of following, B indicates that the surface C according to the conventional rotary vane method shows the cleaning ratio characteristics in the case of the washing tank rotating method considered in advance of the present invention, and the cleaning effect of the present invention is high.

In addition, as described above, the laundry is moved by frictional contact with the main wall of the tank 5 and the container-shaped stirring body 6, so that the greater the amount of the laundry, the greater the frictional force, thereby reducing the degree of movement of the laundry due to the increase in the amount of the laundry. Therefore, the reduction rate of the washing | cleaning effect is small. In addition, when the amount of the laundry is small, the frequency of contact with the circumferential wall of the container agitator 6 is low and the contact friction is extremely small, and the laundry is flowed and washed mainly by the flow of water generated by the rotation of the agitator 6. In this case, as in the case of the conventional rotary blades, the water flow does not become excessively strong, so there is no fear of over-cleaning, and the washing is appropriately performed without regard to the amount of laundry. These mean that the range of laundry amount which can maintain an appropriate cleaning effect is wider than that of the above-mentioned prior art (see FIG. 2).

In particular, in this embodiment, since the inner surface of the container-shaped agitator body 6 is formed on the unevenness (t-3), first, the adhesion of the laundry in the main direction is favorably obtained, so that a strong rubbing action is obtained and rubbed and sucked. The action is also strengthened, while the laundry is easily separated from each other, and the recess (groove 8) is not blocked by the laundry but becomes a passage for water flowing through the centrifugal force to impart a force to push the laundry up. It is easier to fall further upward, and the projection 9 smoothly guides the flow of water downward from the center of the container-shaped agitator 6 to the outside, thereby making the laundry more vigorous and ultimately more powerful. In addition, a more stain-free cleaning effect can be obtained.

In addition, as a structural effect, the protrusion 9 is provided at the bottom central portion of the container-shaped stirring body 6, so that the depth D (FIG. 1) of the recessed part 10 formed on the lower outer side of the protrusion 9 can be deepened. In addition, the washing shaft 13, the recessed part 10, and the fitting depth can be increased more than before, and this improves the fixing strength of the container-shaped agitator body 6, and fluctuations of the container-shaped agitator body 6 at the time of operation. And the distance E (FIG. 1) of the bottom of the drip tray 2 and the outer bottom of the tank 5 can be made small, and at the same time with the main part of the upper end of the tank 5 and the container-shaped stirring body 6. Since the gap F (FIG. 1) can be made small, the washing volume of laundry can be increased without increasing the external dimension of a gas.

Next, the second embodiment shown in FIG. 3 will be described with the same reference numerals as in the first embodiment. (21) protrudes upward at the bottom center of the vessel stirring (6). As a projection, its outer surface forms a conical shape that slopes outwardly.

This conical projection 21 effectively exerts an effect of smoothly inducing water flow inverted up and down during washing, in particular, flowing down from the central bottom of the container-shaped agitator 6 toward the outside, and effectively washes the laundry. The upper and lower reversal is further promoted, and the cleaning effect is greatly improved, and the mounting strength of the container-shaped agitator 6 is structurally improved as described above, and the washing volume can be increased without increasing the external dimension of the gas. The same excellent effect as in Example 1 is obtained.

On the other hand, in the dehydration operation in the above embodiment, after the drain valve 18 is drained, the clutch mechanism and the like (not shown) are operated to integrally rotate the tank 5 and the container-shaped stirring body 6 in one direction. Is written.

In addition, the present invention is not limited to the above embodiment, but may be applied to a washing tank having no dehydration function. Therefore, the main wall of the tank 5 is made non-imaging so that water can be stored therein and the water tank is removed. In addition, the main wall of the vessel-shaped stirring body is gradually composed of a stool from the bottom to the top, and is not limited to the above tapered one, for example, air-like and other gradually reaching the sloping plane. May be only an inner surface of the inner and outer surfaces.

As described above, the washing machine of the present invention is composed of a body and a yogi agitator body which is located in the lower part of the body and is driven forward and backward, so that the laundry is accommodated together with water in the washing tank and the laundry is mainly used when the amount of the laundry is small. Depending on the water flow generated by the container-type agitator, the amount of the laundry increases, allowing the fluid to flow by the contact friction force with the main wall of the container-type agitator, and at the same time, washing is performed by synergy with the frictional force received from the upper wall of the tank. Since it is possible to perform uniform cleaning without damaging the laundry regardless of the amount of the laundry, it is possible to form a protrusion protruding upward from the center of the bottom of the container agitator, and fitting the laundry shaft from the bottom to the proper Can generate upside down water flow, maintain proper cleaning effect and wash It is possible to hold more than one would expect a good cleaning effect with projections washing shaft length fitting, etc. to expand the amount of range, the number of excellent practical effects, such as to improve the mounting strength of the composition for vapor stirred.
