Description

[Detailed Description of the Invention] The present invention aims to provide a washing machine suitable for washing large items such as blankets that are easily damaged by direct contact with the rotary blades without damaging the fabric. It is.

This will be explained below based on the drawings.

Reference numeral 1 denotes a washing tub which also serves as a dehydration tank, and has a large number of small holes 2 for dehydration in its peripheral wall, and a rotary blade 3 is disposed at its bottom.

Further, a balance ring 5 having a liquid 4 sealed therein is attached to the mouth edge of the washing tub 1. Reference numeral 6 denotes an outer tub in which the washing tub 1 is housed, and a drive motor 7 for rotating the rotary blade 3 and the washing tub 1 and a bearing case 8 are attached to the bottom of the outer tub. It is suspended from the upper part of the machine frame (not shown) by a hanging rod 9.

An annular rail groove 10 is formed on the lower surface of the balance IJ ring 5 along the edge of the opening of the washing tub 1, and the lower end of the groove 10 is formed with a rail plate having a slit 11 in the center along the edge of the opening of the washing tub 1. 12, and this rail plate and the rail groove 10 constitute a rail 13.

The upper disk 15 of a slider 14 as shown in FIG. A hook 18 is formed on the lower disc 17 of the slider 14, which is connected to the upper disc 15 by a columnar rattan 16. A plurality of such sliders 14 are inserted into the rail 13. The upper disk 15 or the lower disk 17 may be rotatable about the shaft 16 or fixed to the shaft. Reference numeral 19 denotes a bag of approximately the same size as the washing tub 1, which is placed in the washing tub 1. Its side parts are made of flexible silk 20, and its bottom part is made of a relatively soft, abrasion-resistant bag with no large holes. It consists of a base body 21, and these base bodies 21 and silk 20 are connected by a connecting wire 22.

A green band 23 is sewn to the edge of the net 20, and a plurality of hooks 24 as shown in FIG. 2 are attached to this edge band. This hook 24 is hooked onto the hook 18 of the slider 14. In such a structure, when washing a large item such as a blanket that is easily damaged, the hook 24 of the bag 19 is connected to the hook 1 of the slider 14.
8 and insert the bag 19 into the washing tub 1 as shown in FIG.

In other words, the bag 19 can be freely rotated by the slider 14.
Then, a blanket etc. A is put into this bag 19. At this time, bag 19
It is assumed that the base body 21 is in contact with the rotor blade 3. Then, when water is supplied to the specified water level and the rotor 3 is rotated, a swirling water flow is generated, and this water flow penetrates into the blanket etc. A in the bag 19 and washes the blanket etc. At this time, since the bag 19 is rotatably attached by the slider 14, it is rotated in the direction of rotation by the swirling water flow. Especially in this case, the base 2 of the bag 19
1 comes into contact with the rotor 3, the base body 21 tends to be rotated together with the rotor 3, and the rotation of the bag 19 is promoted. Therefore, the object A in the bag 19 rotates with the rotation of the bag and constantly changes its position, so that the swirling water flow sufficiently penetrates all parts of the object A and washes it evenly. can.

Moreover, since the blanket A is placed in the bag 19 and does not come into contact with the rotor 3, there is no chance of the cloth being damaged. In addition, since the side surface of the bag 19 is made of flexible silk, it is possible to push the contents A toward the washing tub 1 when the bag 19 rotates, resulting in a push-washing effect. It will be done.

Furthermore, when the rotation of the rotary blade 3 is reversed, the bag 19 is twisted,
This twisting produces the same effect as pressing the contents A, and further improves the cleaning power. In addition to blankets, the bag 19 can also be filled with stockings, sweaters, etc. that tend to get damaged. At this time, bag 1
If the amount of laundry in bag 9 is small, the bag will become too light and the swirling water will twist the bag and damage the laundry inside, resulting in a weight at the bottom of bag 19 as shown by the dotted line in Figure 1. A movable disk 25 is fitted with iron so that the bag 19 can rotate smoothly. Hook 24 of bag 19 to slider 14
If the bag 19 is removed from the bag 19, items made of durable fabrics that do not easily get damaged can be washed directly in the washing tub 1 using the rotary blades as before.

4 and 5 show other embodiments of the rail 26 constructed on the lower surface of the balance ring 5. In FIG. 4, the inner side 27 of the rail is integrally molded with the balance ring 5, and the outer side 28 of the rail is fixed to the bottom surface of the balance ring with a screw 29.

In addition, instead of screwing the outside 28 of the rail, Fig. 5 shows a pin 31 that is vertically inserted into the hole 3 provided on the outside 28 of the rail from the underside of the balance ring, and the lower end of the pin is melted 32. It is. Furthermore, Fig. 6 shows a seal 33 formed on the side surface of the balance ring 5, which is made by welding the openings of the two upper and lower annular groove bodies 5' and 5''. Then, annular rail pieces 34 and 35 facing each other are integrally protruded from the inner walls of the double-concave conductors 5' and 5'', respectively, and inside the rail 33 constituted by these rail pieces 34 and 35, as shown in FIG. A rotating part 37 of a slider 36 such as the one shown in FIG.

43 is a hole for hooking the hook 24 of the bag 19.

In this way, the welded portions 38 of the two concave groove bodies 5', 5'' can be covered and hidden by the rail pieces 34, 35 that are close to each other.
Also, in FIG. 8, a flange 39 is similarly protruded from the side surface of the balance ring 5 to serve as a rail. In this case, an annular slider 40 is slidably installed on the rail 39, and the slider 4 is mounted on the rail 39. The bag 19 is fixed to the bag 19 via the connecting odor 41. In this way, when the bag 19 is inserted into or taken out from the washing tub, the slider 40 does not need to be attached to or removed from the slider 14 or 36 as in the previous embodiments. You can work with it on. Here, in order to reduce the friction between the rail 39 and the slider 40, an annular lip 42 is protruded from the slider 40 as shown in FIG. Further, a roller or the like may be attached to the slider. In the above example,
When the bag 19 is inserted into the washing tub 1, the base body 21 of the bag is brought into contact with the rotary blade 3 to promote rotation of the bag. As shown in FIGS. 10 and 11, radial blades 44 may be vertically provided on the back surface of the base body 21, and the rotation of the bag 19 may be promoted by receiving the swirling water flow from the rotary blades.

Furthermore, although the washing tub also serves as a dehydration tub, it goes without saying that the present invention can also be applied to a simple washing tub. As described above, according to the present invention, a silk-like bag is rotatably inserted into a washing tub, a blanket or other material that is likely to be damaged is placed in the bag, and the rotary blade is rotated. It is possible to wash items in the swirling water flow generated by the rotary blades without the objects coming into contact with the rotary blades, that is, without causing damage to the fabric.

In addition, since the bag is rotated by the swirling water stream, the objects inside the bag are rotated and their positions are constantly changed, and the swirling water stream penetrates evenly to obtain a good cleaning effect. This method is particularly effective for large items such as blankets, which conventionally have insufficient fabric circumference, because the rotation of the bag generates fabric circumference, and the fabric does not get damaged. Furthermore, since the bag is rotatably supported at the top of the washing tub, there is no fear that the bag will sink into the water while the bag is rotating, and the laundry inside can be reliably protected.

In addition, the deformation of the bag during rotation also provides a push-washing effect, further improving the cleaning effect. Furthermore, by bringing the bottom of the bag into contact with the rotary blades, or by providing radial blades on the back surface of the bag to receive the swirling water flow instead of contacting the bottom of the bag, the rotation of the bag can be promoted and the cleaning effect can be further improved.
