Description

[Detailed description of the invention] The present invention simultaneously washes laundry that is made of thick fabrics such as jeans or cotton, which are difficult to cause fabric damage, and laundry that is thin, such as synthetic fibers, that are prone to fabric damage. The aim is to obtain a washing machine that can do the following.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on figures showing one embodiment. Reference numeral 1 denotes a washing tub which also serves as a dehydration tub, and has a large number of small holes 2 for dehydration in its peripheral wall, and a rotating shaft 3 protrudes into the washing tub from its bottom. Rotating axis 3
There is a drive shaft 20 of the washing tub 1 on the outer periphery of the washing tub 1 . 4 is an outer tub in which the washing tub 1 is housed, and a rotating shaft 3 is attached to the bottom of the outer tub.
A drive motor 5 for rotating a drive shaft 20 and a bearing case 6 are attached, and the outer tank 4 is suspended from the upper part of a machine frame (not shown) by a hanger having a vibration damping mechanism. A balance ring 8 having a liquid 7 sealed therein is attached to the mouth edge of the washing tub 1.

An auxiliary washing container 9 is attached to the rotating shaft 3 by tightening a screw 12 to the upper end of the rotating shaft 3. This container 9 has a cylindrical shape, and has a plurality of vertically long protrusions 13 formed on its inner wall, and a plurality of blades 14 protruding from its outer wall. Also, there are many small holes 15 in the side wall of this container.
is provided.

In such a configuration, when trying to wash items that are less susceptible to fabric damage, such as jeans, and items that are more likely to cause fabric damage, such as synthetic fibers, laundry A that is more likely to cause fabric damage is placed in the container 9, and laundry A that is more likely to cause fabric damage is placed in the container Laundry B is placed between the container 9 and the washing tub 1, and water is supplied to the specified water level H. When the drive motor 5 is driven to rotate the rotary shaft 3, the container 9 rotates, so that the laundry A in the container 9 is pushed outward by centrifugal force, resulting in a washing action and the protrusion 13. The scrubbing effect created by lightly rubbing against each other allows the fabric to be washed without damaging it. If the rotary shaft 3 is stopped periodically, the laundry A will rub against the projections 13 due to inertia each time the rotary shaft, that is, the container 9, stops, thereby increasing the scrubbing effect. Furthermore, if the direction of rotation of the rotating shaft is changed periodically, this scrubbing effect becomes even more pronounced.

On the other hand, the laundry B between the container 9 and the washing tub 1 is washed by a strong water flow generated by the agitation action of the blades 14 protruding from the outer wall of the container, and by a scrubbing action caused by direct rubbing against the blades 14.

In other words, material A that is easily damaged and material B that is not.
and can be washed inside and outside the container 9 at the same time.

When washing is finished, the drain valve 16 is opened to drain the liquid in the washing tub 1 and container 9 through the drain channel 17. Then, rinse in the same way as washing.

When rinsing is completed, the washing tub 1 is rotated at high speed to dehydrate the washing tub B between the container 9 and the washing tub 1. At this time, the rotating shaft 3 is also rotated at high speed at the same rotation speed as the washing tub 1 by a clutch mechanism (not shown). The container 9 also rotates at high speed. Therefore, the water contained in the laundry A in the container 9 is also dehydrated through the small holes 15 by centrifugal force. In this case, the inner diameter of container 9 is
Since it is smaller, the centrifugal force exerted on laundry A is smaller than the centrifugal force exerted on laundry B, and laundry A will not be damaged.

In this way, in the embodiment shown in FIG.
Item A that is prone to fabric damage and item B that is not.
Not only washing but also dehydration can be performed simultaneously inside and outside the container 9.

In addition, although a small hole 15 is provided in the peripheral wall of the container 9 in FIG. 1, if the small hole 15 is not provided, the flow of liquid between the inside and outside of the container 9 will be cut off, so that colored items and white items cannot be separated. It is also possible to wash both at the same time.

Further, protrusions 13 and blades 14 are provided on the inner and outer walls of the container 9, respectively, to wash the laundry A and B, but even without such protrusions or blades, the point is to prevent the laundry from being exposed to impact. It may be anything that provides an impact part that gives a strong impact. FIG. 3 shows another embodiment of the container 9, in which a projection 18 is provided outward from the side wall, and this projection 18 serves as the vane 14 in FIG. It also serves as the protrusion 13 in the figure.

As described above, according to the washing device of the present invention, the rotating shaft at the bottom of the washing tub has impact parts (protrusions 13 and vanes 1
By installing an auxiliary laundry container with 4), it is possible to wash laundry items that are prone to damage, such as synthetic fibers, and laundry items that are less likely to cause damage, such as jeans, at the same time inside and outside this container. This eliminates the need to separate the laundry into several batches for each type as in the past, which saves time and simplifies the process.

Moreover, since the laundry in the auxiliary laundry container is pressed against the side wall of this container by centrifugal force, the weight of the laundry is not applied to the bottom of the container 9, which corresponds to the position of the conventional rotor, and the drive motor On the other hand, the presence of the auxiliary laundry container reduces the amount of laundry that gets tangled with each other, making it easier to take out the laundry. It is something.

If the rotating shaft is periodically stopped during washing, the scrubbing effect of the impact part of the laundry in the auxiliary washing container can be improved, and if the auxiliary washing container is made non-porous, It is also possible to wash colored items and white items at the same time inside and outside the container. Furthermore, as in the embodiment, the washing tub is also used as a dehydration tub, and a large number of small holes are provided in the peripheral wall of the auxiliary washing container.
If the rotating shaft, ie, the container, is made to rotate at the same speed when the washing tub is rotated at high speed, it is possible to simultaneously wash and dehydrate items that are easily damaged and items that are not.

Furthermore, if the auxiliary washing container is removed from the rotating shaft and a conventional rotary blade is attached to this rotating shaft, it is possible to wash a large amount of laundry at once in the washing tub using the rotary blade.
