Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehydrator configured to perform so-called dewatering and rinsing.

Conventionally, in a dehydrator that performs so-called dewatering and rinsing, in which the washed laundry is placed in a rotating spinning tank and the laundry is rotated at high speed and centrifugally dehydrated while being injected with water and rinsed, the water injection hose is placed above the rotating tub. Some have a structure that allows them to be inserted into the opening/closing lid. This structure has the drawback that the hose outlet is formed in the opening/closing lid, which impairs the appearance. Another conventional example that prevents this problem is to provide a water inlet on the inner surface of the opening/closing lid and connect this to the water inlet via a bellows hose inside the outer box. However, according to this configuration, since the water inlet body is always connected to the water inlet, if the user forgets to close the water tap leading to the water inlet and opens the opening/closing lid, water may splash out of the machine from the water inlet body, causing the user to The problem was that it would sprinkle on the floor.

The present invention has been made to eliminate the above-mentioned drawbacks, and its purpose is to prevent opening and closing even when a water receiver for water injection that receives water from a water supply unit connected to a water source such as a tap is provided in an opening/closing lid. Water is no longer automatically supplied to the water receiver when the lid is opened, and water is discharged from the water receiver to the outside of the machine when the lid is opened due to forgetting to close the water source plug. To provide a dewatering machine that can reliably prevent this and also prevent water from backflowing and overflowing from a water receiver due to its force during water injection.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a dehydration receiving tank of a two-tub type washing machine, which is arranged side by side with a washing tank 3 in an outer box 2. This is equipped with a well-known dehydration basket 4, which is a rotating tank for dehydration, and its upper end Near the opening 5, a cloth pressing plate 7 having a central opening 6 can be detachably attached. Reference numeral 8 denotes a fountain tube with a large number of fountain holes 9 formed around it, which is located at the center of rotation within the dewatering basket 4 and stands upright at its inner bottom, and its upper end serves as a cloth presser plate 7 when it is in the installed state. It passes through the central opening 6 in a non-contact manner. 1
Reference numeral 0 designates a lid plate having a laundry loading/unloading port 11 formed in a portion facing the upper end opening 5 of the dehydration basket 4. Inside the laundry loading/unloading port 11, there is an opening/closing lid 12 made of a transparent material that can be opened and closed freely. It is provided via a hinge shaft 13, and the cover plate 10 is attached to the open upper end of the dewatering tank 1. 14 is an outer lid located above the opening/closing lid 12. Reference numeral 15 denotes a water receiver having a circular bottom shape, and its upper edge is integrally attached to the lower surface of the opening/closing lid 12 by appropriate means. below,
This water receiver 15 will be explained in detail. That is, 16
is a short cylindrical water inlet portion formed in the center of the bottom wall of the water receiver 15 at a position facing the upper end of the water fountain tube 8;
17 is a partition wall 19, 2 which is introduced into the water receiver 15 by penetrating its outer circumferential wall 18 and extending substantially linearly.
0, and its outer peripheral wall 18
The part that opens outside serves as a water socket 21. 2
Reference numeral 2 denotes a water supply pipe installed in the operation box 2a so as to function as a water supply unit connected to a water source, for example, a water supply, and its water outlet end 23 is connected to the water receiver 15 when the opening/closing lid 12 is closed. Water supply part 17
Although it is mechanically separated from the water socket 21 of the opening/closing lid 12, it is positioned, for example, close to and facing the water socket 21 so as to form a corresponding relationship that allows water to pass through when the opening/closing lid 12 is in the closed position. There is. Reference numeral 24 denotes a main water passage, one end of which extends in an approximately arc shape as a whole so as to communicate with the water supply receiving portion 17 in an approximately tangential direction, and the other end of which is a approximately circular water conduit near the entrance of the water inlet portion 16. It communicates with the recess 25. The main water passage 24 is defined by an overflow bank 26 on the outside thereof and an intermediate partition wall 27 on the inside. and,
The overflow bank 26 has a protrusion height lower than that of the partition walls 19 and 20 and is continuous with one of the partition walls 19, and the overflow bank 26 and the outer peripheral wall of the water receiver 15 18 and the first detection waterway 2
8 is formed. This first detection waterway 28 is therefore adjacent to the outside of the main waterway 24 via the overflow bank 26 along the main waterway 24, and its bottom wall in particular is formed higher than that of the main waterway 24. ing.
Reference numeral 29 denotes a second detection waterway located inside the main flow waterway 24 and extending along the main waterway 24, which is an extension of the partition wall 20 that surrounds the circular water confluence recess 25 over approximately half its circumference, and the middle partition wall 27. In particular, the bottom wall of the second detection water channel 29 is formed to be gradually lower than that of the main water flow channel 24 in the downstream direction. Reference numeral 30 designates a plate-shaped eddy current suppressing member that prevents water from turning into a vortex in the water confluence recess 25 and passing through the water inlet portion 16 while rotating. It is placed near the entrance. Reference numeral 31 denotes a terminal partition wall for smoothly flowing water into the water confluence recess 25, and an outlet section 32 for the first detection channel 28 is formed between this terminal partition wall and the terminal end of the overflow bank section 26. ing. In addition, the main waterway 2
4 and the first detection waterway 28 are also gradually inclined in the direction of water flow.

Next, the operation of the above structure will be explained. First, dehydration and rinsing is performed as follows. That is,
The laundry that has been washed in the washing tank 3 is transferred to the water receiver 15.
Open the opening/closing lid 12 that integrally has the dehydration basket 4.
After that, the cloth holding plate 7 is attached as shown in FIG. 2, and the opening/closing lid 12 is then rotated to the closed position. As a result, the water inlet portion 16 of the water receiver 15 faces the upper end of the water fountain tube 8 . After that, when you open the water faucet (not shown), water flows through the water supply pipe 22 and the water socket 21 of the water receiver 15.
Finally, the water inlet 16 of the water receiver 15 is
When the spinner basket 4 is rotated at high speed in this state, the water is sprayed onto the laundry from the fountain hole 9 of the fountain tube 8, and passes through the laundry due to its centrifugal dewatering action. Water is discharged into the dehydration receiving tank 1 from a group of dehydration holes provided on the outer periphery of the dehydration basket 4, and dewatering and rinsing is performed by continuing such action. During dehydration rinsing with continuous water injection, the opening/closing lid 12 is opened without closing the water tap.
When the water receiver 15 is opened, the water receiver 15 integrated therewith is also rotated upward together with the opening/closing lid 12, so that the water supply receiver 17 in the water receiver 15
The water inlet 21 is located at a position where water cannot be received due to the previous relationship where water can be received, that is, the water outlet end 23 of the water supply pipe 22.
The water supply receiving part 1 is moved out of the range facing the water supply part 1.
7 is not automatically conducted, so when the opening/closing lid 12 is opened, water may be discharged from the water inlet 16 and splash onto the user or wet the surrounding floor. Prevents water from being released outside. Next, the flow of water within the water receiver 15 will be described in detail.
That is, from the water outlet end 23 of the water supply pipe 22 to the water supply receiving part 17
Of course, if the water flow rate is appropriate, the water supplied through the water inlet 21 will flow into the second detection waterway 29, which forms the lowest bottom wall, but at the same time, the water will flow into the second detection waterway 29, which forms the lowest bottom wall. The water flows into the water channel 24, passes through it, flows out into the water confluence recess 25 in a spiral shape, and is discharged from there into the fountain tube 8 via the water inlet 16. On the other hand, when the water supply flow rate to the water supply receiving section 17 is large, the water overflows from the overflow bank section 26 into the first detection channel 28 while passing through the main water channel 24, and the overflow water is ultimately The water flows out from the outlet portion 32 of the first detection waterway 28 toward the water confluence recess 25 . On the other hand, when the water supply flow rate to the water supply receiving section 17 is low, most of the water flows into and passes through the second detection channel 29 whose lower wall is lower than that of the main water channel 24. . In this way, when the water supply flow rate to the water supply receiving part 17 is appropriate, water passes through both the main water passage 24 and the second detection water channel 29, and when it is low, almost only the second detection water channel 29 is passed. street, and if there is too much, the first detection waterway 2
8, and when the user confirms this state by looking through the opening/closing lid 12 made of transparent material,
It is possible to easily judge whether or not the flow rate of water injected into the dewatering basket 4 from the water inlet part 16 of the water receiver 15 is appropriate, and this allows the user to adjust the water flow rate such as adjusting the opening of the water faucet. This can prevent uneven rinsing and wasteful use of water. Further, according to the above configuration, the main water passage 24, the first detection waterway 28, and the second detection waterway 29 are configured to extend in an arc shape from the water supply receiving portion 17 to reach the vicinity of the water inlet portion 16, so that water is The water flows from the water supply receiving part 17 toward the water inlet part 16 while being forced to change its direction in a spiral shape, and the water force is gradually weakened, so that the water flow becomes smooth and due to the backflow of water from the water receiving part 21. Overflow can be prevented.
In such a configuration, the eddy current suppression member 30
Assuming that there is no water flowing into the water confluence recess 25
The water becomes a whirlpool inside and passes through the water inlet part 16 while rotating, and as a result, water at the lower discharge end of the water inlet part 16 is scattered around by rotational centrifugal force and falls outside the upper end of the water fountain tube 8. There is a concern that a cavity will be created within the water inlet portion 16 and that the opening area will not be utilized effectively. However, according to the above embodiment,
Since the eddy current suppression member 30 is provided upright on the periphery of the water inlet portion 16, the eddy current phenomenon of water at the periphery is suppressed by the eddy current suppression member 30, and there is no concern as described above. Note that the eddy current suppressing member 30 may not only be provided on the periphery of the water inlet portion 16 but also in the water inlet portion 1.
6 may be provided in a rib shape on the inner surface.

As described above, the present invention provides a water receiver having a main channel extending in a substantially arc shape from a water supply receiving portion to a water inlet portion on the opening/closing lid side located above a rotating tank for dewatering. , and the water inlet of the water supply part and the water outlet end of the water supply part connected to the water source are configured to face each other so that water can pass through at the closed position of the opening/closing lid. As a result, water is no longer automatically supplied to the water supply receptacle, and it is therefore possible to reliably prevent water from being discharged from the water inlet to the outside of the machine due to the opening of the opening/closing lid caused by forgetting to close the water source tap. In addition, since the main channel for guiding water from the water inlet to the water inlet is formed in a substantially arc shape, it is possible to provide a dewatering machine that has excellent effects such as weakening the water force and preventing backflow overflow caused by the water force. .
