Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine that performs so-called dehydration and rinsing, and more particularly to a washing machine that has an improved water supply structure.

Conventionally, dehydration rinsing has been an attempt to effectively rinse the laundry by sprinkling water on it after washing with detergent and dehydrating it, and there is no concept of doing this in dehydrating washing machines as well. be. However, in conventional washing machines with both dehydrating and dehydrating functions, this is done by supplying water from the water inlet of the water supply device into the interior of the rotating washing/dehydrating tank, that is, into the center of the rotating tank. Therefore, at this time, the laundry scattered around the tub receives centrifugal force due to the rotation of the tub, and water is not directly and effectively applied to it, so the dehydration and rinsing process is delayed. The drawback was that it was not very effective.

The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to enable water to be directly and effectively applied to the laundry in the rotating tub, thereby effectively dehydrating and rinsing the laundry, and at the same time To provide a washing machine for dehydrating and dehydrating, which can protect a user from a tank and prevent it from getting wet due to splashing of water.

Embodiments of the present invention will be described below with reference to the drawings. First, in the first embodiment shown in FIGS. 1 to 4, 1 in FIG. 1 is an outer box, and 2 is an outer box 1. 4 is a washing shaft 5 vertically disposed approximately at the center of the bottom of the outer tub 2.
9 is a motor disposed on one side (left side in the figure) of the mechanism section 4, and 10 is a belt transmission mechanism that connects the motor 9 and the mechanism section 4. . On the other hand, 11 is a drain port formed at the bottom corner of the outer tank 2 on the other side (right side in the figure) of the mechanism section 4, and this has a drain valve 12.
A drain hose 13 is connected to the drain valve 12, and an overflow hose 14 is connected to the drain hose 13 at its base. Then 15
is a rotary tub for both washing and dewatering, which is disposed inside the outer tub 2 and attached to the dehydrating shaft 6; a pulsator 16 is disposed approximately in the center of the inner bottom of this tub, and the pulsator 16 is connected to the washing shaft 5; On the other hand, a balance ring 17 is attached to the upper opening edge of the rotating tank 15.
A cover ring 18 is attached to the upper opening edge of the outer tank 2, and a water sprinkler 19 is removably fitted and held in this cover ring 18 as a non-rotating part. It is positioned at the upper part like a lid that closes off almost the entire area. Here, as shown in FIG. 2 in detail, the water sprinkler 19 has an annular depression in the inner peripheral part of the outermost flange part 19a, and a large number of small water passage holes 19c at the bottom of the depression part 19b. It consists of a circular container with a hole in it, and a plurality of claws 19 on the lower surface of the flange portion 19a.
d, and its claw 19d is attached to the cover ring 18.
It is elastically engaged with the inner edge of. In addition, the bottom of the water sprinkler 19 is thereby connected to the inside of the balance ring 17, which has become a part of the rotating tank 15, and thus the rotating tank 1.
It is located within 5. Reference numeral 20 designates a top plate on the outer box 1, which has an opening 21 for loading and unloading the laundry, and a lid 22 for opening and closing the opening 21. An operation box 23 is provided protrudingly provided, and in addition to the operation control device 24, a water supply device 27 consisting of a water supply valve 25, a water supply gutter 26, etc. is disposed thereon.
The tip of the water supply gutter 26 faces into the water sprinkler 19.

Now, in the case of this embodiment configured as above,
There are two types of operation: the "standard course" shown in Figure 3a and the "saving course" shown in Figure 3b. In other words, the rotating tub 15 is rotated intermittently by the motor 9, thereby first supplying water to the laundry in the rotating tub 15 while dewatering it, and then only supplying water to the dehydrated laundry. Combined with a moderate centrifugal force due to the inertial rotation of the rotating tank 15, the water is uniformly soaked, and then water is supplied and dewatered again.
After that, only water supply is repeated, thereby performing dehydration rinsing that effectively removes the detergent contained in the laundry after "washing" (detergent washing). Regarding the water supply at that time,
Water is supplied from the water supply gutter 26 to the water sprinkler 19 based on the opening of the water supply valve 25 of the water supply device 27. When water is supplied in this way, the water sprinkler 19 distributes the received water to the bottom of the surrounding depression. The water is diffused and supplied from the small hole 19c to the inner periphery of the rotating tank 15 as shown in FIG. Ivy laundry 28
Because of this location, the water supplied as described above is effectively applied directly to the laundry 28, and thus dewatering and rinsing can be performed more effectively. Also, in this case, the water passage small hole 19 of the water sprinkler 19
Because the bottom part where c is located is located inside the rotating tank 15, all of the water supplied from the small water passage hole 19c, including splashed water, does not leak out of the rotating tank 15 and flows into the rotating tank 15. Therefore, it can also be supplied to the laundry 18, and the effectiveness of sprinkling on the laundry 18, in other words, the effect of dewatering and rinsing can be further enhanced. In addition to this, since the water sprinkler 19 is positioned like a lid that covers almost the entire upper part of the rotating tank 15,
Even when the lid 22 is opened during dehydration or dehydration rinsing, the user is prevented from touching the rotating tank 15 which continues to rotate due to inertia.
In addition, the sprinkler 19 prevents the supplied water from splashing against the laundry and coming out of the rotating tub 15 when water is supplied. Therefore, it is possible to prevent the entire side from getting wet due to splashing of water.

For the specific method of "dehydration rinsing", please refer to
Water may be supplied continuously and the rotating tank 15 may be continuously rotated at a constant speed.

On the other hand, FIG. 5 shows a second embodiment of the present invention, in particular, this one uses a water sprinkler 29 with a deeper bottom than the water sprinkler 19 described above, and connects it to the pivot shaft 22a of the lid 22. Top plate 2 as a non-rotating part using
By doing so, when loading and unloading the laundry, the lid 22 is opened, the sprinkler 29 is also raised, and the sprinkler 29 is placed against the lid 22. It is possible.

Further, FIG. 6 shows a third embodiment of the present invention, in which the above-mentioned sprinkler 29 is pivotally supported on the top plate 20 via a link 30. The water sprinkler 29 can be raised and stood as shown in FIG.

Furthermore, FIG. 8 shows a fourth embodiment of the present invention, in which the water sprinkler 19 described above is pivoted to the cover ring 18, also a non-rotating part, by a shaft 31 so as to be movable up and down. In addition, a spring body, for example, a torsion coil spring 32 wound around the shaft 31, is provided at the pivot portion to bias the water sprinkler 19 in the upward rotational direction. The sprinkler 19 can be easily raised.

FIG. 9 shows a fifth embodiment of the present invention, in which the bottom is formed into a concentric step shape as shown in FIGS. 10 and 11, and the stepped portion is utilized. A water sprinkler 34 is used, each of which has a large number of small water passage holes 19c, and a display section with a character display or a numerical display, especially a display section 33 that indicates the appropriateness of the water supply amount. By doing so, it is possible to supply an appropriate amount of water to each laundry according to the amount (distribution) of laundry, especially in the 12th
As shown in the figure, even when there is a large amount of laundry 28 not only in the periphery but also in the center of the rotating tub 15, uniform water supply can be achieved with an appropriate amount of water.

Incidentally, the display section 33 may be formed by using the slope of the sprinkler 35 having a sloped bottom as shown in FIG. 13 to display the above-mentioned characters or numbers.

Furthermore, in this case, the total area of the water passage holes 19c in the excess water supply display part of the display section is set to be larger than the total area of each water passage hole 19c in the other display parts, and thereby It is also possible to prevent water from overflowing from the water sprinkler 34.

Furthermore, in this case, as shown in FIG.
By forming an opening 36 in the center of the display and attaching a see-through plate 37 to the opening 36, it is possible to see through the display, allowing more accurate and easier confirmation of the amount of water supplied. can.

However, the present invention is not limited to the embodiments described above and shown in the drawings, and may be implemented with appropriate modifications within the scope of the invention.

As described above, in summary, the present invention provides at least a peripheral portion that is positioned like a lid in a non-rotating part above a rotating tank used for both washing and dehydration, and diffuses water supplied from a water supply device into the inner part of the rotating tank. A water sprinkler having a large number of small water passage holes is provided at the bottom of the rotary tank so that the bottom of the water sprinkler is located within the rotating tank, so that during dehydration and rinsing, the washing inside the rotating tank is Water can be applied directly to objects without leaking, allowing for effective dehydration and rinsing. At the same time, it protects the user of the rotating tank and prevents it from getting wet due to water sloshing around. It is possible to provide a washing machine that can perform both dehydration and dehydration.
