Description

[Detailed Description of the Invention] The present invention relates to a rinsing dehydrator in which a water injection container is provided above the rotation tank for pouring water into the water spray cylinder of the rotation tank during dewatering and rinsing.

Conventionally, in this type of rinsing dehydrator, a water injection container with a water injection port formed at the bottom for injecting water into a water spray tube is provided above the rotating tank, and a water injection container is provided on the upper surface of the water injection container on the peripheral wall of the water injection container. A transparent container lid having an engaging claw that engages with the engaging hole is attached by the engaging means. However, according to the above configuration, since the container lid is attached to the top surface of the water injection container, there is a drawback that the cost is high, and when cleaning the water injection container, the engaging claw of the container lid is removed from the water injection container. The lid had to be removed by pulling it out from the engaging hole, which was troublesome to clean, and the engaging claw broke, making it impossible to reattach the container lid to the water injection container.

The present invention was developed in view of the above circumstances.The purpose of the present invention is to eliminate the need for a container lid attached to the water injection container, thereby reducing costs, simplifying cleaning, and making the water injection container open at the top. To provide a rinsing dehydrator which does not cause water to scatter outward from a water injection container despite the presence of water.

An embodiment in which the present invention is applied to a two-tub washing machine will be described below with reference to FIGS. 1 to 3. 1
is an outer box, and inside of this box, a washing tub 2 and a water receiving tank 3, which are integrally molded from plastic in a juxtaposed state, are housed. Reference numeral 4 denotes a rotary tank having a large number of dewatering holes 4a, which is rotatably disposed within the water receiving tank 3 and is rotated by a drive motor 5. Reference numeral 6 denotes a water sprinkler tube installed inside the rotating tank 4, which is formed by, for example, sintering resin powder and having countless micropores on the peripheral wall, and rotates together with the rotating tank 4 to spray water into the interior. Water is sprinkled into the rotating tank 4 by centrifugal force. 7
is a water injection switching lever that selectively supplies tap water to the washing tub 2 and the water receiving tank 3. Reference numeral 8 denotes an upper cover attached to the upper opening of the water receiving tank 3, and a laundry loading/unloading port communicating with the upper opening of the rotary tub 4 is formed in this upper cover. Now, reference numeral 9 denotes a water filling container with an open top, and hinge shafts 10 provided on the left and right sides of the rear end are rotatably supported on the rear part of the upper cover 8, so that the water filling container 9 can be rotated upward. Upper cover 8
The laundry inlet/outlet provided in the laundry can be opened. The peripheral wall 11 of the water injection container 9 is formed into a U-shape with a substantially arcuate front half.
Reference numeral 12 designates a water inlet body as a water inlet formed at the bottom of the water inlet container 9 so as to protrude downward, and a crisscrossing rib 13 is integrally formed at the upper end of this body. Reference numeral 14 denotes a guide protrusion protruding substantially parallel to the left end portion of the peripheral wall 11, and an inflow portion 15 is defined between this and the peripheral wall. 16 and 1
Reference numerals 7 denote first and second guide protrusions, which are provided on the inner bottom surface 9a of the water injection container 9, and these first and second guide protrusions 16, 1
7 has one end facing the inner surface of the peripheral wall 11 via gaps 18 and 19 of a predetermined size as notches, and the other end thereof is directed toward the water inlet body 12. The protrusion height of the first guide protrusion 16 near the inflow portion 15 is set to be greater than that of the second guide protrusion 17. Reference numerals 20 to 22 denote first to third bank portions which are bulgingly formed at the rear portion of the water injection container 9, and an overflow portion 23 is formed at the right end portion of the first bank portion 20 on the upper stage side. The middle second bank 21 is formed to have the same protrusion height as the guide protrusion 14, and the lower third bank 22 has approximately the same protrusion height as the second guide protrusion 17. The tip of the third embankment 22 is connected to the water inlet body 1.
A protrusion 24 extending in two directions is provided. The gate when molding the above-mentioned water injection container 9 is located at the center of the lower surface of the rib 13, and 25 is a protrusion that is the mark of this gate. Note that 26 is a pulsator disposed at the inner bottom of the washing tub 2, and 27 is a transparent lid rotatably provided above the water receiving tub 3.

Next, the operation of this embodiment with the above configuration will be described. The lid 27 and the water pouring container 9 are rotated upward, respectively, and the laundry that has been washed in the washing tub 2 is transferred around the water sprinkling tube 6 in the rotating tub 4. After that, the water pouring container 9 and the lid 27 are rotated downward. Turn the water injection switch lever 7 to
Switch the selection to the water receiving tank 3 side, and open the water faucet. Then, the water flows into the inflow portion 15 of the water injection container 9 through a water supply channel (not shown), and flows into the first guide protrusion 16, the second guide protrusion 17, and the protrusion 24.
The water is guided through the water inlet body 12 and injected into the water spray tube 6. In this state, when the drive motor 5 is driven to rotate the rotary tub 4 at high speed, the water in the water sprinkling tube 6 is sprinkled onto the laundry from the peripheral wall of the water sprinkling tube 6, and further passes through the inside of the laundry and is transferred to the rotary tub 4. The detergent contained in the laundry is discharged from the dehydration hole 4a into the water receiving tank 3, whereupon the laundry is rinsed and dehydrated by centrifugal dehydration.

The water supplied to the inlet 15 in the water injection container 9 flows along the inner surface of the peripheral wall 11 as shown by arrows A, B, and C, but a portion of the water is diverted when passing through the gap 18. The arrow D is
As shown in FIG.
When passing through, a part of the flow is diverted by the second guide protrusion 17 as shown by the arrow E, and is gradually guided away from the inner surface of the peripheral wall 11 and toward the water inlet body 12, and as shown by the arrow C The water flowing along the inner surface of the water inlet 11 is guided to the water inlet body 12 by the protrusions 24 as shown by arrow F. By the way, if the water faucet is opened too wide and the water flow as shown by arrow C increases, some of the water will go over the second and third embankments 21 and 22 as shown by arrow G and flow into the overflow area. 23 and overflows into the water receiving tank 3. Therefore, the user only needs to observe this situation while looking through the lid 27 and adjust the water faucet to supply an appropriate amount of water to the water injection container 9.

According to this embodiment configured in this way, the following effects can be obtained. That is, the peripheral wall 1 is provided on the inner bottom surface of the water injection container 9.
Since the first and second guide protrusions 16 and 17 are provided with gaps 18 and 19 from the inflow part 1
A part of the water flowing in from 5 is smoothly diverted by the guide protrusions 16 and 17,
The divided water is guided to the water inlet body 12 by the first and second guide protrusions 16 and 17 and the protrusion 24.

By the way, conventionally, after the water supplied to the water injection container flows along the inner surface of the circumferential wall formed in a substantially arc shape, the water is flowed along the inner surface of the circumferential wall formed in a substantially arc shape, and then is guided by a guide rib that protrudes from the inner bottom surface of the water injection container and has one end connected to the peripheral wall. It is designed to guide you towards the water inlet body. At this time, the water that has reached the guide ribs is not diverted in any way and the flow direction is suddenly changed toward the water inlet body, causing it to collide with the guide ribs and splash upwards. It had come to collide with the inner surface of the container lid. Therefore, if the container lid is omitted with the conventional structure as it is, the water that has splashed up will overcome the peripheral wall and overflow onto the top surface of the cover.
However, in this embodiment, gaps 18 and 19 are provided as notches between the peripheral wall 11 and the first and second guide protrusions 16 and 17.
The first and second guide protrusions 16 and 17 gradually separate the inflowing water and direct it toward the water inlet body 12, so that the flow direction of the water is suddenly changed and the water is This will surely prevent the container from popping up, and therefore, even if the container lid is omitted, there is no risk of the problem that would occur if the container lid was simply removed from a conventional structure. The cost can be reduced by omitting the lid, and when cleaning the water injection container 9, it can be easily cleaned by simply opening the lid 27, and furthermore, the water injection container 9 can be easily cleaned by simply opening the lid 27, and the container is conventionally attached to the top surface of the water injection container by an engaging means. Since the lid is omitted, there is no risk of breakage of the engaging claw.
In addition, the first guide protrusion 16 adjacent to the inflow portion 15
Since the projecting height is set larger than that of the second guide protrusion 17, even if a large amount of water is supplied from the inflow part 15, some of the water will be blocked by the first guide protrusion 16. water can be reliably guided in the direction of the water inlet body 12, and a large amount of water will not go over and pass through the first guide protrusion 16, thereby preventing water from flowing wastefully toward the overflowing part 23. can be sufficiently prevented. In addition, in this embodiment, since the protrusion 25 generated by the gate during molding is positioned on the lower surface of the intersection of the crisscrossing ribs 13, the protrusion 25 does not protrude from the lower surface of the water inlet body 12.
Therefore, troublesome post-processing such as cutting off the protrusion or scraping it off with a file can be omitted.

Furthermore, in this embodiment, since the criss-crossing ribs 13 are provided at the inlet portion of the water inlet body 12, the first and second guide protrusions 16 and 17 and the protrusion 24 form the water inlet body. The water guided toward 12 is rectified by the ribs 13 and flows smoothly into the water inlet body 12, resulting in the effect that water can be well injected into the water spray tube 6. In addition, with the conventional structure, the water overflowing from the overflowing area is observed through transparent plastic windows provided on each of the plastic lid and the container lid, making it difficult to see the overflowing area due to the reflection of light. Although it had some drawbacks, the present embodiment has the advantage that it is easier to see than the conventional method because there is no container lid and the container can be observed only through the transparent plastic window provided in the lid 27.

FIG. 4 shows another embodiment of the present invention, and only the parts different from the above embodiment will be explained below. That is, 28 and 29 are first and second guide protrusions that replace the first and second guide protrusions 16 and 17, respectively, and one end of each of these extends to the peripheral wall 11. , cutouts 30 and 31 of a predetermined size are formed on one end side of these to form the low protrusion 2.
8a and 29a are formed.

According to the other embodiment with the above configuration, the water flow indicated by arrow A is partially guided as indicated by arrow D by the low protrusion 28a of the first guide protrusion 28. Although a large amount of water flow can be produced in the direction of arrow D, it is prevented from violently colliding and flying up as in the previous embodiment, and furthermore, the water flow shown by arrow B is unified by the low protrusion 29a of the second guide protrusion 29. Part arrow E
Since the water is guided as shown by , a large amount of water flow in the direction of the arrow E can be generated, and the water can be prevented from flying up violently as described above. Furthermore, the force of the water flowing along the peripheral wall 11 is weakened by passing over these low protrusions 28a and 29a, which has the advantage that the force of the water flow inside the water injection container 9 can be made weaker than in the previous embodiment, and the force of the water flow is reduced. This has the effect of preventing wasteful overflow of water from the overflowing portion 23 due to this, and of reliably guiding the water flow to the water inlet body 12.

As is clear from the embodiments described above, the present invention has a notch formed between the inner bottom surface of the water injection container and the peripheral wall, and a guide protrusion that guides water from the inlet toward the water injection port. This reliably prevents water from colliding violently with the guide protrusion and scattering upwards, so the container lid attached to the water injection container can be omitted, reducing costs and making cleaning easier. To provide a rinsing dehydrator in which water does not scatter outward from a water injection container even though the water injection container has an open top surface.
