Description

[Detailed description of the invention] The present invention relates to a dehydrator that can perform rinsing in a dehydration tank, and includes a dehydration lid that is provided with a spout that discharges supply water in a radial direction, and a water supply that is supplied from this spout. The water supply channel is fixed in the vertical direction so that sufficient water can be supplied to the lower part of the laundry from this water supply channel, and the opposing relationship between the spout and the water inlet of the water supply channel is ensured even when the spinner tank rotates. It has been made possible to do so.

This type of dehydrator is equipped with a dehydrating lid to prevent the laundry from being pulled out, so rinsing water is supplied through the dehydrating lid. The supplied rinsing water gradually infiltrates from the top to the bottom of the laundry, but this takes time, so one idea was to create a gap in the inner circumferential wall of the tank and introduce the overflow water, allowing it to infiltrate from the bottom. However, if water is supplied while the dehydration tank is rotating, overflowing water may be directly dehydrated, resulting in insufficient water supply to the lower part. Therefore, we created a system in which the water outlet in the radial direction of the dehydration lid faces the water inlet of the water supply channel provided on the inner wall of the tank, so that water can be reliably supplied to the water supply channel even when the dehydration tank rotates and centrifugal force is exerted. it was thought. However, when the dehydration tank rotates eccentrically or continues to rotate, the dehydration lid shifts, making it impossible to maintain the opposing relationship between the water spout and the water inlet.

In order to maintain the opposing relationship between the water spout and the water inlet and ensure water supply, this invention engages the protrusion of the water spout in the slit of the water inlet, and connects the water supply channel and the dewatering lid in the rotational direction. It is engaged.

Below, the diagrams of the example will be explained.
is a cylindrical dewatering tank of a two-tub washing machine, which is rotated continuously or continuously by a lower motor (not shown), and has dewatering holes 2 bored in the wall of the tank. There is. Reference numeral 3 denotes a substantially triangular water supply cylinder which is removably 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 twill 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 water outlets 10 are provided throughout the upper and lower regions.

Here, the upper lid 12 forms a notch 16 that faces and surrounds each water inlet 9 of the buttful plate 6 when it is connected to 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 about 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 gap, and a low upward partition wall 24 is formed to partition the guide walls 22, 22 within the remaining 30 degrees, and a partition wall 24 is formed between the partition wall 24 and each lower part of the outer guide wall 22. An engagement floor 25 is formed so as to bridge, and a guide wall 2 is provided at the counterclockwise end.
A barrier wall 26 is formed to integrally connect the partition walls 2, 22 and the partition wall 24, and the upper part of the barrier 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 connect the upper lid 12 and the hand 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 13, 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.

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 continuously, it follows the rotation, and the spout 38 is surely opposed to the water inlet 9. A water supply port 39 of a water supply device is opposed to the upper center of the upper cover 12, and the upper end of the water supply cylinder 3 is closely opposed to the lower center of the lower cover 13, and is surrounded by a recess 34.

Next, a case in which laundry is rinsed in the dehydration tank 1 will be described. The laundry in the washing tub is transferred to the dehydration tank 1, and the dehydration lid 11 is inserted. Then, before supplying water from the water supply port 39, the laundry is first dehydrated and the washing water is shaken off. Thereafter, water is continuously supplied from the water supply port 39, and the dehydration tank 1 is rotated continuously or continuously. This rotation can be selected using 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 introduction hole 17.
It reaches the filter 14 through... Then, it falls from the outlet hole 33 onto the top of the laundry, and the water supply tube 3
The water enters the middle and lower part of the laundry through the water outlet 5, and further enters the water supply channel 7 formed by the three full plates 6 from the three water outlets 38 via the water inlet 9, and falls. The water enters all over the top and bottom of the laundry from the water outlet 10. As the dehydration tank 1 rotates, the water that has entered the laundry is transferred to the dehydration hole 2.
...and by repeating this process, the laundry will be rinsed. The water supply from the water supply port 39 is stopped at an appropriate time, and then a dewatering process is performed to dehydrate the rinsed laundry, and at this point, the rinsing process and the dewatering process in the dehydrating 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... Furthermore, the ribs 18 prevent objects that would directly collide with the center and scatter to the surroundings. Therefore, the fallen supply water flows through the ribs 18.
The water is rectified by the water, suppresses splashing, and quickly flows into the introduction holes 17. Also, the sound of water splashing is reduced.

In this way, the dehydrator according to the present invention has a plurality of radial water spouts in the dehydration lid through which rinse water is supplied, and also forms a water supply channel in the vertical direction on the inner circumferential wall of the dehydration tank. Since the water spout is made to face the water spout and the protrusion of the water spout is inserted into the slit of the water inlet, the dehydration lid can be engaged with the water supply channel in the rotational direction, and the water spout can be reliably opposed to the water inlet. I can maintain this. Therefore, even if the dehydration tank rotates eccentrically or is operated intermittently, water can be reliably supplied to the water supply channel and sufficient rinsing water can infiltrate the laundry in the lower part.
