Description

[Detailed Description of the Invention] The present invention relates to a dehydrator that can perform rinsing in a dehydration tank, and particularly aims to allow rinsing water to sufficiently penetrate into the lower part of the laundry in the tank.

Conventionally, in this type of dehydrator, water was supplied to the dehydrating tank through the dehydrating lid, and the supplied water entered from the upper part of the laundry to the lower part. However, as it is, the infiltration speed is slow and the rinsing time becomes long.To solve this problem, a net-shaped water supply cylinder with approximately the same diameter is installed on the inner peripheral wall of the dehydration tank in advance, and the water overflowing at the top is drained into the cylinder. The idea was to introduce water into the gap between the inner circumferences and supply water to the lower part in a short time. However, during this water supply process, the dewatering tank rotates continuously or intermittently, exerting centrifugal force, and while it is stopped, the lower part can be adequately supplied with water as mentioned above, but while it is rotating, it overflows. The water was directly drained out of the tank, and the water supply to the lower part was still insufficient. Therefore, the rinsing effect could not be satisfied as it was.

In addition, even when water was supplied from above and from the sides, the laundry in the center of the tub did not receive sufficient water.

The present invention ensures water supply to the lower part and also to the laundry in the center part.

Below, the diagrams of the example will be explained.
is a cylindrical dehydration tank of a two-tub washing machine, which is rotated continuously or intermittently by a lower motor (not shown), and has dehydration holes 2 bored in the tank wall. There is. Reference numeral 3 denotes a substantially triangular water supply cylinder detachably installed in the center of the inner bottom of the dehydration tank 1, with a flow regulator 4 provided at the upper opening, and a water outlet 5 on the ridge line at the middle and lower part of the cylinder wall. It is drilled. 6 are buttfull plates fixed vertically at three locations on the tank wall in the dehydration tank 1 at intervals from each other, forming vertical supply channels 7 between them and the tank walls, and vertically installed at the top. A water inlet 9 constituted by a slit 8 in the direction is provided, and a water outlet 10 is provided throughout the upper and lower regions.

11 is an upper lid 12 and a lower lid 1 molded from soft resin.
A substantially disc-shaped dehydration lid consisting of 3, which supplies enough water to the dehydration tank 1 when rinsing is performed in the dehydration tank 1, and a filter 14 for removing rust from the water.
It is inserted removably into the lower part of the constriction 15 formed at the upper opening edge of the dehydration tank 1 using its own elasticity, and is prevented from coming off by the constriction 15. be done.

Here, the upper lid 12 forms a notch 16 facing and surrounding each water inlet 9 of the buttful plate 6 at the peripheral edge that is connected to the lower part of the constricted portion 15, and bulges upward. A concave dish-shaped center part is provided in the center part, and introduction holes 17 and upwardly protruding ribs 18 are formed in this center part in a radial manner that alternately rises up to the peripheral wall, and the three places in the bulging center part are formed. 120 for

Arc-shaped punch holes 21 with a rotation angle of 60 degrees are formed at intervals of 120 degrees, and upward guide walls 22 are arranged in parallel at both ends of each punch hole 21.
Guide walls 22, 22 within a range of about 30 degrees counterclockwise
A roof member 23 is formed to cover the space between the guide walls 22, 22, and a low upward partition wall 24 is formed to partition the guide walls 22, 22 within the remaining 30 degrees. An engagement floor 25 is formed so as to bridge, and a guide wall 2 is provided at the counterclockwise end.
2, 22 and the partition wall 24, an upper part of the partition wall 26 protrudes clockwise, and a downward engaging piece 27 is formed on this protrusion. Incidentally, on both sides of the downward protrusion 19, connecting pieces 28 are formed which are connected to the respective rising peripheral walls of the bulging central part and the concave central part.

Next, the lower lid 13 is formed with grooves 29 that protrude somewhat at 120 degree intervals at three locations on the periphery, and the other portions are made to stand up to form a peripheral wall, and at the top of the peripheral wall. partially forms a flat surface 30. In addition, at three locations between the concave grooves 29..., inverted U-shaped engagement grooves 31 are formed by extending the peripheral wall further upward by a width of about 30 degrees and continuously bending outward and downward. However, an engaging pawl 32 is formed protruding from the counterclockwise end of the outer wall of the engaging groove 31. Furthermore, a lead-out hole 33 is radially bored in the center part, and an annular downward recess 34 is formed surrounding the center part. The pieces 35 are arranged radially and slenderly in a radial manner between the outlet holes 33. A weir plate 36 lower than the peripheral wall is provided in the communication path from this central part to the groove 29,
Two projecting pieces 37, 37 are provided at the tips of the grooves 29, respectively.

The upper and lower lids 12 and 13 are integrally molded with each other.

When constructing the dehydration lid 11 from the upper and lower lids 12 and 13, first place the filter 14 on the lower lid 13 at the center and the support pieces 35, and then insert the upper lid 12 into the handle hole 2.
Pinch and polymerize from above using 0... During this superposition, the roof member 23 of the guide walls 22, 22 is passed through the hole 21 and covered over the engagement groove 31, and the upper lid 12 is placed over the engagement groove 31.
The lower surface of the periphery is brought into close contact with the flat surface 30 of the lower lid 13, and the downward protrusion 19 and the recessed center portion are pressed onto the filter 14. Next, from this state, the upper cover 12 is rotated clockwise to engage the engagement groove 31.
straddles the partition wall 24, and the filter 14
The upper cover 12 is rotated approximately 30 degrees while suppressing the elasticity by the contact between the outer lower end of the engagement groove 31 and the floor surface of the engagement floor 25, and the engagement claw 32 is pressed against the engagement piece 27 by its own elasticity. Use this to engage. Then, the upper and lower lids 12 and 13 are connected to each other in the rotational direction and the vertical direction to form the dehydration lid 11, and the filter 14 is also connected to the upper and lower lids 1.
The grooves 29 of the lower lid 13 face the notches 16 and together with the upper lid 12 form water spouts 38.

When inserting the completed dehydration lid 11 into the dehydration tank 1, the water supply channel 7, which is made up of each double plate 6...
While visually checking through the notches 16, insert the notches 16 into each of the 8-shaped water inlets 9 of the

…is faced to the water inlet 9…. And each protrusion 3
7... is inserted into the vertical slit 8 from above. Therefore, the dehydration lid 11 is restrained from moving in the rotational direction because the protrusions 37 engage with the slits 8 in the rotational direction, and even if the dehydration tank 1 rotates eccentrically or intermittently, it follows the rotation, and the spout 38 is surely opposed to the water inlet 9. A water supply port 39 is opposed above the center of the upper lid 12, and the upper end of the water supply cylinder 13 is closely opposed to the lower center of the lower lid 13, and is surrounded by a recess 34.

Next, the case where the laundry is rinsed in the spin tub 1 will be described. The laundry in the washing tub is transferred into the spin tub 1, and the spin lid 11 is inserted. Then, before supplying water from the water supply port 39, the laundry is first spin-dried to shake off the washing water. After this, water is continuously supplied from the water supply port 39, and the spin tub 1 is rotated continuously or intermittently. This rotation can be selected by a timer knob (not shown).

Regardless of which option is selected, water that falls from the water supply port 39 enters the dish-shaped center of the top cover 12 and enters the water introduction hole 17.
It reaches the filter 14 via... Then, it falls to the upper part of the laundry from the outlet hole 33, enters the water supply cylinder 3, and enters the middle and lower part of the laundry from the water outlet 5.
Further, from the three water spouts 38, the water enters the water supply channel 7 constituted by each split plate 6 via the water inlet 9,
While falling, the water infiltrates from the water outlet 10 all over the top and bottom of the laundry. The water that has entered the laundry in this way is discharged from the dehydration holes 2 as the dehydration tank 1 rotates, and by repeating this process, the laundry is rinsed. The water supply from the water supply port 39 is stopped at an appropriate time, and then a dehydration process is performed to dehydrate the rinsed laundry, and at this point, the rinsing process and dehydration process in the dehydration tank are completed.

The water that falls from the water supply port 39 into the dish-shaped center of the upper lid 12 collides with the upwardly protruding ribs 18, flows around each rib 18, and flows directly into the introduction hole 17.
It flows into... Further, the ribs 18 prevent the particles from colliding directly with the center and scattering to the surrounding area. Therefore, the fallen supply water flows through the ribs 18...
The water is rectified by the water, suppressing splashing, and quickly flows into the water guide holes 17. Also, the sound of water splashing is reduced.

In this way, the dehydrator according to the present invention has a downward water guide hole and a plurality of radial water spout holes in the dehydration lid that receives the supplied water, and the water inlet of the vertical water supply channel is opposed to the water spout hole. Therefore, rinsing water can be discharged from substantially the entire upper and lower regions of the water supply channel and can enter the laundry. In addition, instead of supplying overflow water to the bottom, the water spout is placed opposite the water inlet of the water supply channel, so even if the dehydration tank is rotating and centrifugal force is working, water can be reliably supplied to the water supply channel. , which can reliably supply water to the laundry from the top to the bottom.

Moreover, since water is supplied from the water guide hole to the water supply cylinder located approximately in the center, water can sufficiently penetrate into the laundry at the center.
