Abstract

PURPOSE:To prevent water centrifugally dehydrated from jumping to the outside passing the drain hole of the drain receiving part of a tub cover when performing dehydration by providing a parting plate part to close the upstream side of a rotary tub in a dehydrating rotating direction at the inward aperture of an inundation port, and providing the drain hole at the upstream side of the rotary tub in the dehydrating rotating direction at the drain receiving part of the tub cover. CONSTITUTION:The upstream side in the dehydrating rotating direction P of the inward aperture 16b of the inundation port 16 is closed with the parting plate part 10. Therefore, since the water splashed to the upstream side of the inward aperture 16b of the inundation port 16 is abutted against the parting plate part 19, it is prevented entering into an inundation drain part 15. On the other hand, the water splashed to the downstream side of the inward aperture 16b of the inundation port 16 enters into the inundation drain part 15 passing the downstream side, however, at this time, since the drain hole 17a of the drain receiving part 17 of the tub cover 14 is provided at the upstreams side in the dehydrating rotating direction P of the drain receiving part 17, it is possible to prevent the water jumping to the outside passing the drain hole 17a of the drain receiving part 17 since no drain hole is provided at the upper side even when the water entering into the inundation drain part 15 is raised with an up-draft air current.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a dehydrating and washing machine having an overflow drain section on a tub and a drain receiving section on a tub cover.

(Prior Art) An example of this type of dehydrating and washing machine is shown in FIG. In this Fig. 6, A has a rotating tank for both washing and dehydration (
(not shown), a tab cover B is provided on the upper edge of the tab A, and an overflow drain part is provided with an overflow port C that opens inwardly and upwardly on the upper side wall of the tab A. It is provided on the tab A. A drainage receiving part E is provided on the tub cover B so as to close the upward opening of the overflow port C, and a drainage hole F communicating with the overflow drainage part is provided in this drainage receiving part E. In this configuration, tab A
When the water supplied inside exceeds the overflow level, the water is discharged from the inward opening of the overflow port C through the overflow drainage section.

On the other hand, when wastewater discharged from a clothes dryer (not shown) placed above the washing machine is discharged and treated on the washing machine side, the wastewater is passed through a drain hose (not shown) led out from the clothes dryer to the washing machine. It is received in the drain port of the upper cover (not shown). Then, this drainage water is guided to the drainage receiving part E of the tub cover B through a tubular drain passage (not shown) provided in the upper cover, and the water is then directed from the drain hole F of the drainage receiving part E to the overflow drainage part. It is discharged through.

(Problems to be Solved by the Invention) In the conventional configuration described above, when the water that has been centrifugally dehydrated from the laundry is shaken off from the rotating tank during dewatering (especially when an unbalanced state occurs), the large amount of water is The portion hits the inner wall of tub A and is discharged from a drain provided at the bottom of tub A. However, some of the water enters the overflow drain section through the inward opening of the overflow port C, and furthermore, the above water flows into the drain receiving section E of the tub cover B due to the upward air flow generated by the rotation of the rotating tank. Occasionally, it would leak out through drain hole F.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a dehydrating and washing machine that can prevent water centrifugally dehydrated from laundry from flowing out through a drain hole in a drain receiving part of a tub cover during dewatering.

[Structure of the Invention] (Means for Solving the Problems) The dehydrating and dehydrating washing machine of the present invention includes a tub in which a rotating tub for both washing and dehydrating is provided, and a tub cover provided on the upper edge of the tab. an overflow drain part provided on the tub and having an overflow port opening facing inwardly and upwardly at the upper side wall of the tub, and provided in the tub cover so as to close the upward opening of the overflow port. In the drain receiving part having a drainage hole communicating with the overflow drainage part, a partition plate part is provided for closing an inward opening of the overflow opening on an upstream side in the dewatering rotation direction of the rotary tank, and A feature is that the drainage hole is provided in the drainage receiving part on the upstream side in the rotational direction of dehydration of the rotary tank.

(Function) During dehydration, water centrifugally dehydrated from the laundry is shaken off from the rotating tank. Since the water is thrown off almost tangentially to the rotating tank, in the conventional system where the inward opening of the overflow port is completely open, the splashed water is mainly upstream of the inward opening of the overflow port in the direction of dewatering rotation. Air tends to rise as well as jump into the overflow port from the side. On the other hand, according to the above means, since the upstream side of the inward opening of the overflow port in the direction of dewatering rotation is closed by the partition plate, the amount of splashed water entering the overflow port is reduced, and the upward There is also less air flow. Even if water enters the overflow port and rises due to air flow, the drainage hole in the drainage receiving part is provided on the upstream side of the drainage receiving part in the direction of dewatering rotation.
There is no drainage hole above it, so water can be prevented from flowing out through the drainage hole.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 5.

First, in FIGS. 3 and 5, a tab 3 is disposed within an outer box 1 of a washing machine with a dehydrating function via an elastic suspension mechanism 2. As shown in FIGS. A rotary tank 4 for both washing and dehydration is disposed within the tub 3. A container-shaped stirring body 5 is disposed within the rotating tank 4 . A motor 6 and a mechanism section 7 are provided on the outer bottom of the tab 3. Note that 8 is a drain valve provided at the drain port of the tub 3, and 9 is a drain hose connected to the drain valve 8 and led out of the outer box 1.

Further, an upper cover 10 is provided at the upper part of the outer box 1, and an entrance/exit for clothing (not shown) is formed in this upper cover 10. The upper cover 10 is provided with a bifold lid 11 that opens and closes the above-mentioned entrance/exit. Here, as shown in FIG. 4, a drain port 12 is provided on the back side of the upper cover 10, and a clothes dryer (not shown) located above the main body of the washing machine is connected to the drain port 12. A drain hose 13 led out from the machine is connected.

On the other hand, as shown in FIG. 5, an annular tab cover 14 is provided at the upper peripheral edge of the tab 3. As shown in FIG. Tab 3
As shown in FIGS. 1 and 2, an overflow drainage section 15 is provided on the outer circumferential portion of the side wall so as to protrude outward.

Drainage passage section 15 formed at the lower part of this overflow drainage section 15
g communicates with the drainage hose 9. Overflow drainage section 1
An overflow port 16 is formed at the top of the tub 5 and opens inwardly and upwardly from the top of the side wall of the tub 3. A drainage receiving portion 17 is provided at a portion of the tub cover 14 corresponding to the overflow drainage portion 15 so as to close the upward opening 16a of the overflow port 16.
is formed. This drainage receiving part 17 is the overflow drainage part 15.
It has a funnel shape with a drainage hole 17a communicating with the
The drain hole 17a is formed in the dehydration rotation direction (first direction) of the rotary tank 4.
It is disposed on the upstream side (direction indicated by arrow P in the figure), that is, on the right side in the figure. As shown in FIG. 4, the other end of a tubular drain passage 18 provided in the upper cover 10 and connected to the drain port 12 at the other end is connected to the drain receiving portion 17 from above. I'm making it happen. This results in
The waste water discharged from the clothes dryer is received through the drain hose 13 into the drain port 12, and the waste water is guided through the drain passage 18 to the waste water receiving part 17 of the tub cover 14, thereby causing the waste water to overflow from the drain hole 17a of the waste water receiving part 17. Drainage section 15
It is designed to be discharged through. On the other hand, as shown in FIG. 1, the partition plate part 19 is attached to the tub 3 so as to close the right side in the figure, which is the upstream side of the inward opening 16b of the overflow port 16 in the dewatering rotation direction P of the rotary tank 4. It is formed.

Next, the operation of the above configuration will be explained.

First, when the water supplied into the tub 3 exceeds the overflow level, that is, the lower edge of the inward opening 16b of the overflow port 16 shown in FIG. 15 and is discharged from the drain hose 9 through the drain passage section 15a at the lower part thereof. On the other hand, when discharging wastewater discharged from a clothes dryer placed above the washing machine, the wastewater is passed through a drain hose led out from the clothes dryer to the drain port of the upper cover 10 of the washing machine. Received on 12th. Then, this drainage water is guided to the drainage receiving part 17 of the tub cover 14 through a drain passage 18 provided in the upper cover 10. As a result, drained water enters the overflow drain section 15 through the drain hole 17g of the drain receiving section 17, and is discharged in the same manner as described above.

In addition, during spin-drying, when the water centrifugally dehydrated from the laundry is shaken off from the rotating tub 4, most of the drained water scatters in the tangential direction of the rotating tub 4, hits the inner wall of the tub 3, and It is discharged from the drain port provided at the bottom of 3. on the other hand,
A portion of the water hits the overflowing hole 16 of the tub 3. At this time, since the upstream side of the inward opening 16b of the overflow port 16 in the dewatering rotation direction P is blocked by the partition plate portion 19, some of the water is scattered to the upstream side of the inward opening 16b of the overflow port 16. Since the objects hit the partition plate part 19, they do not enter the overflow drainage part 15. On the other hand, some of the water that has scattered to the downstream side of the inward opening 16b of the overflow port 16 passes through the downstream side and enters the overflow drain section 15, but at this time, the water that has flown to the downstream side of the inward opening 16b of the overflow port 16 enters the overflow drain section 15. Drain hole 1
7a is provided on the upstream side of the drainage receiving part 17 in the dewatering rotation direction P, so even if the water that has entered the overflow drainage part 15 rises due to the upward air flow, there is no drainage hole above it. Therefore, drained water can be prevented from flowing out through the drainage hole 17a of the drainage receiving portion 17.

In the above embodiment, the partition plate portion 19 is provided integrally with the tab 3, but a separate partition plate may be attached to the tab.

[Effects of the Invention] As is clear from the above description, the present invention provides a partition plate portion that closes the inward opening of the overflow port on the upstream side in the dewatering rotation direction of the rotating tank, and also Since the drainage hole is provided on the upstream side of the rotating tub in the direction of dewatering rotation, it is possible to prevent the water centrifugally dehydrated from the laundry from flowing out through the drain hole in the drain receptacle of the tub cover during dewatering. It has this excellent effect.
