Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic liquid dispenser for a dehydrating/washing machine which utilizes centrifugal force to dispense liquid.

Conventional Structure and Problems Conventionally, this type of automatic liquid dosing device has a liquid dosing container that can be detachably attached to a part of a vibration-suppressing balance ring that is installed at the upper opening edge of the inner tub of a washing machine that also serves as a dehydrator. The liquid agent is moved from the liquid agent input container to the liquid agent holding chamber on the balance ring side by using centrifugal force when the inner tank rotates at high speed, and is transferred to several holding chambers provided in the balance ring. The liquid is introduced sequentially and then introduced during rinsing operation, but with this configuration, when moving from the liquid injection container to the liquid holding chamber of the balance ring, the liquid that has been injected is ensured to protrude from the communication port and work effectively. If the liquid holding container is not attached to the balance ring, it may not be held securely, and during high-speed rotation it may fall off the balance ring and fall into the inner tank, damaging the liquid injection container or flying out of the inner tank, resulting in injury to humans. There was a strong possibility that it would pose a danger to 'Furthermore, since the liquid agent input container is detachably attached to the balance ring, the mounting structure becomes complicated, and as a result, the number of parts increases, resulting in an increase in cost.

It has a pulsator 8 at the bottom. 9 is a motor, and the power of this motor 9 is transmitted by a V-belt, and is also transmitted to the inner tank 7 and the pulsator 8 via a mechanism section 10.

11 is a balance ring provided on the upper opening edge of the inner tank 7;
Reference numeral 2 denotes a liquid agent automatic injection mechanism section of the present invention provided in a part of the balance ring 11. The parallax 27g 11 is formed by liquid-tightly welding annular groove bodies 111L and 11b made of synthetic resin with a hot plate or the like so as to have a cavity inside, and liquid is sealed in the cavity.

FIG. 2 shows a part of the balance ring 11 provided with the liquid agent automatic injection mechanism 12 of the present invention. A liquid agent storage chamber 14 is provided below the injection hole 13 and is comprised of an annular groove body 11a and 11b.

Figure 3 shows the automatic liquid dispenser (
Reference numeral 17 indicates a plurality of chambers in the entire portion 12, and below the injection hole 13, there is a liquid agent storage chamber 1 as described above.
4, and an outlet portion 15 is provided at the upper part of the outer wall surface of the liquid agent storage chamber 14.

Further, a first rotation holding chamber 16 is arranged adjacent to the outlet section 15 of the liquid agent storage chamber 14 so as to communicate with the outlet section 15 .

Reference numeral 17 denotes a stop-time holding chamber that communicates with the first rotation-time holding chamber 16 through a passage 18, and this stop-time holding chamber 17 is provided with a liquid agent outflow window 19 on the upper side wall of the inner tank 7 on the side opposite to the center of rotation. . 2o is a second holding chamber during rotation adjacent to the first holding chamber 16 during rotation and the holding chamber 17 during stoppage, and communicates with the holding chamber 17 during stoppage via the liquid agent outflow window 19. 21 is the second
The outlet 21 communicates with the holding chamber 2o through a passage 22 during rotation, and the outlet 21 is connected to the inside of the inner tank 7. Then, ribs provided from the inner bottoms of the annular groove bodies 111L and 11b of the rehabilitation balance ring 11 for partitioning each room and passageway are welded and formed.

Further, the outlet portion 16 from the liquid agent storage chamber 14 and the liquid agent outflow window 19 from the holding chamber 17 at the time of stop are respectively connected to the liquid agent storage chamber 1.
4 and the stop holding chamber 170, it is located at the farthest point from the rotation center of the inner tank 7, and the side walls of these rooms are covered with liquid material due to centrifugal force when the inner tank 7 rotates at high speed. It is sloped so that all the remaining parts can be moved to the next first rotational holding chamber 16 and second rotational holding chamber 2o.

Further, the first rotational holding chamber 16 and the second rotational holding chamber 2o each have an inclined bottom surface, and the passage 18 is provided with a step. As a result, when the inner tank 7 is stopped, the liquid agent is guided by gravity to the holding chamber 17 and the outlet 21 at the next stop.

Next, the principle of operation of this liquid agent automatic injection mechanism section 12 will be explained based on FIGS. 4 and 5.

First, a liquid, for example, a softening agent, is injected into the liquid storage chamber 14 from the injection hole 13 on the upper surface of the balance ring 11 .

The injected liquid drops from the injection hole 13 into the liquid storage chamber 14 and accumulates therein. During normal washing operation, the inner tank 7 is stationary, and the liquid up to 'i' is held in the liquid storage chamber 14. This state is shown in FIG. 5(A). After the washing operation is finished and the water is drained, when the inner tank 7 starts rotating for centrifugal dewatering, the balance ring 11 and automatic liquid injection mechanism 12 also rotate, and the liquid in the liquid storage chamber 14 is moved by centrifugal force. Therefore, it is pressed against the side wall and rises up the wall surface. The liquid agent that has reached the outlet portion 16 at the upper part of the outer peripheral wall surface flows into the first rotational holding chamber 16 on the balance ring 11 side.
It also sticks to the wall.

This state is shown in FIG. 5(B).

When dewatering is completed and the rotation of the inner tank 7 is stopped, the liquid agent falls to the bottom of the first rotating holding chamber 16 due to gravity and flows into the stopping holding chamber 17 through the passage 18 due to the slope of the bottom surface. During this time, a rinsing operation following water supply to the inner tank 7 is executed, and the liquid agent remains held in the holding chamber 17 during stoppage. This state is shown in (8) of FIG.

After the rinsing operation and draining are completed, when the inner tank 7 starts rotating again for centrifugal dehydration, the liquid flows from the stop holding chamber 17 to the second liquid outflow window 19 due to the centrifugal force, just as described above. During rotation, it flows into the holding chamber 20 and sticks to the wall surface.

This state is shown in FIG. 6 (CO).

When dehydration is completed and the rotation of the inner tank 7 is stopped, the liquid agent falls to the bottom of the second rotating holding chamber 2o due to gravity, and flows through the passage 22 due to the slope of the bottom surface to the outflow port 21, just as described above. flows into. At this time, the inner tank 7 has started a rinsing operation following the next water supply.

Since the outlet 21 communicates with the inner tank 7, the liquid agent is poured into the rinsing water.

Let us now discuss the relationship with the dehydration rotation speed.

After washing 1M operation and draining, foaming during dewatering 11
- In the intermittent dehydration operation of Nodame, the first rotation holding chamber 16
The liquid agent stuck to the wall falls to the bottom due to gravity and starts moving to the next room.The rotation speed is 1oo~2001', p, m.
Therefore, the dehydration rotation speed should always be kept at 20 Or, p, m or more. In addition, when starting spin-drying, the vibration of the inner tub 7 increases due to the laundry being shifted to one side, and the safety device is activated and the spin-drying rotation stops.The maximum rotation speed is 50 to 10.
0 r, p, m, so if the size of the liquid outflow window 19 is small and it is installed at a high position, the liquid can already flow into the second rotation holding chamber 20 at this time and be thrown in early. You can prevent it from getting stuck. For this reason, the control valve can be eliminated.

Note that in the above embodiment, the liquid agent automatic injection mechanism section 1
2 is provided with one liquid injection hole 13, and first and second holding chambers 16 and 20 during rotation and a holding chamber 17 during stoppage are provided respectively. By appropriately increasing the number of injection holes 13 and the holding chambers during rotation and holding chambers during stoppage, it is possible to accommodate an arbitrary number of spin-drying operations, and a wider range of washing cycles can be obtained.

Effects of the Invention As described above, according to the present invention, since the liquid agent automatic injection mechanism is integrated with the balance ring, it is small and lightweight, and there is no leakage when moving the liquid, and unlike the conventional one, Since the detergent storage chamber is not separate from the balance ring, there is no uncertainty when attaching the balance ring, and therefore, the risk of damage to the equipment or to the human body can be eliminated.

In addition, since it is formed integrally with the balance ring, the number of parts can be reduced, the cost can be reduced, and the mass production efficiency can be improved, which is of great industrial value.
