Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehydrating and washing machine in which additives such as bleach or antistatic agents are placed between a rotary tank and a water receiving tank so as not to damage the laundry.

In recent years, the rotating tank has been formed into a tapered shape that expands upward, and the water that is removed from the laundry during spin-drying is pumped up by rotational centrifugal force, and the water is pumped from the discharge section formed in the upper part to the upper outer periphery of the water receiving tank. A dehydrating and dehydrating washing machine has been considered in which the water is discharged into the drainage space of an annular body formed in the cylindrical body. If the laundry is put into the water tank, the laundry will come into direct contact with the additive and the fabric will be damaged or yellowed, so to prevent this, add the additive into the water tank and drain the water It is desirable that when the water flows into the rotary tank from the communication hole formed in the bottom wall of the rotary tank by the pumping action caused by the rotation of the stirring blade, the water flows into the rotary tank together with the water.

However, in this type of dehydrating and dehydrating washing machine, the water released from the rotating tank during dehydration is discharged into an annular body formed at the top of the water receiving tank. In order to save water, the gap between the two tanks is designed to be as narrow as possible, since this eliminates the inconvenience of the space between the tank and the water receiving tank being filled with bubbles.

Therefore, it is difficult to introduce additives into the water receiving tank through such a narrow gap between the two tanks, and it is difficult to introduce additives directly into the rotating tank or into the drainage space of the annular body. This may cause inconvenience such as spillage.

The present invention was developed in view of the above circumstances, and its purpose is to bulge out a predetermined portion of the upper circumferential side wall of the water receiving tank toward the drainage space of the annular body, so that the receiver forms a concave portion, while the annular body By providing an introduction body having an outlet facing the recess at the upper end of the receiver, and further providing an input body having an outlet facing the introduction body at the upper end of the outer box, additives can be easily and reliably introduced. To provide a washing machine for dehydration and dehydration which can be put into a water receiving tank.

Incidentally, this input body 34 is closed simultaneously with the opening 10a of the lid 10 when the lid 11 is closed.

Next, the operation of this embodiment configured as described above will be described.

After putting laundry and detergent into the rotating tub 4 through the opening 10a of the lid 10, when the timer device is set,
Water is supplied into the rotary tank 4 and the water receiving tank 1 through a water supply device (not shown), and reaches a predetermined water level (lower than the normal washing water level), for example, as shown by the two-dot chain line A in FIG. Then, a water level switch (not shown) is activated in response to the air pressure in the air trap 25 depending on the water level, and based on this, the water supply is stopped, and the motor 21 is energized to rotate the stirring blades 18. A so-called detergent washing operation is performed.

Then, due to the pump action accompanying the rotation of the stirring blades 18,
Since the water in the water tank 1 is sucked into the rotating tank 4 through the communication hole 23, the water level in the water tank 1 is, for example, indicated by the solid line B in FIG.
On the other hand, the water level in the rotary tank 4 rises to the normal washing water level as shown by the solid line C.

When the detergent washing operation is completed, the drain valve 27 is opened, so that the water in the rotating tank 4 and the water receiving tank 1 flows through the drain port 24 and the connection hose 26. The water is drained out of the machine via the drain valve 27 and the drain hose 28 in this order.

After this, a so-called intermediate dehydration operation is performed before rinsing, and the rotating tank 4 is rotated at high speed.

At this time, the drain valve 27 is in an open state, but the water removed from the laundry due to the rotational centrifugal force is mainly pumped up along the inner peripheral surface of the rotating tub 4 as shown by arrows 36 and 37, and eventually It jumps out from the upper discharge part 6 with force in a substantially horizontal direction, is stopped by the circumferential wall of the annular body 8, and is directly discharged into the drain space 7, connecting the drain port 29°, the connecting hose 30, and the drain hose 28. It is ejected out of the aircraft through the air.

Note that the water discharged from the rotating tank 4 contains a large amount of detergent and tends to foam, but the water is discharged only into the drainage space 7 and not into the water receiving tank 1. Since it is possible to eliminate inconveniences such as the space between the rotating tanks 4 being filled with bubbles and applying large rotational resistance to the rotating tanks 4, it is possible to narrow the gap between the two tanks 1 and 4 and to save water. be.

Now, when the above dehydration operation is completed, water supply and
A so-called rinsing operation is performed in which rinsing consisting of washing and drainage is repeated a predetermined number of times.

When a predetermined amount of an additive, such as bleach, is poured into the input body 34 during the final rinse, this bleach falls into the introduction body 32 from the outlet 35 of the input body 34, and further flows into the introduction body 32. The receiver falls into the recess 31 from the outlet 33 and dissolves into the water in the water tank 1 as it is.

This bleach flows into the rotating tub 4 along with the water sucked into the rotating tub 4 from the communication hole 23 by the pump action accompanying the rotation of the stirring blade 18, and effectively acts on the laundry. .

In addition, since the stirring blade 18 rotates forward and reverse at predetermined intervals not only in the detergent washing operation but also in the rinsing operation, water flows out between the water receiving tank 1 and the rotating tank 4 each time the rotation direction is changed. The bleaching agent is diffused and the concentration of bleaching agent in the water receiving tank 1 and the rotating tank 4 does not differ and is therefore uniform.

After the final rinsing is completed, the water receiving tank 1 and the rotating tank 4 are filled.
When the water inside is discharged, the rotary tub 4 is rotated at high speed, shakes off the water from the laundry, performs a dehydration operation, and completes the washing.

At this time as well, the water discharged from the rotating tank 4 is discharged as it is into the drainage space 7 of the annular body 8, as in the case of the intermediate dewatering operation described above.

As described above, according to this embodiment, since the additive such as bleach is put into the water receiving tank 1, the laundry does not come into direct contact with the additive, and it is possible to prevent damage and yellowing of the fabric.

Moreover, once the additive is poured into the input body 34 formed on the lid body 10, the input body 34, the introduction body 32, and the receiver are placed in the recess 31.
Since the water is automatically poured into the water receiving tank 1 through the water tank 1 in this order, the pouring operation can be performed extremely easily.

Furthermore, it is necessary to provide an interval of a predetermined height and width sufficient to allow water discharged from the discharge section 6 to pass between the outlet 33 of the introduction body 32 and the upper end of the peripheral wall of the rotating tank 4. It is not possible to adopt a configuration in which the additive is extended downward and its lower end is located in the water receiving tank 1, and therefore, the additive must be passed from above into the water receiving tank 1 from the outlet 33, and such a configuration is not possible. Despite the circumstances, the gap between the water receiving tank 1 and the rotating tank 4 should be made as narrow as possible in order to save water. Since the receiver bulged toward the 7 side and formed a recess 31,
Even if the gap between the water receiving tank 1 and the rotating tank 4 is narrow, and even if the outer box 2 is installed with a slight incline, the water can be reliably removed without spilling the additive into the rotating tank 4 or the drainage space 7. The water can be poured into the receiving tank 1, so there is no need to widen the gap between the tanks 1 and 4 in order to ensure reliability of charging, and water can be saved.

In addition, the input body 34. The introducer 32 and the receiver recess 31 can be used when introducing general additives used in washing, such as not only bleach but also antistatic agents and liquid detergent, into the water receiver tank 1. It is.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with various modifications without departing from the gist thereof.

As is clear from the above description, the present invention enables additives to be easily and reliably introduced into the water tank without impairing the water-saving effect, and effectively prevents laundry from becoming damaged or yellowing. It is possible to provide a dehydrating and washing machine that is capable of dehydrating and dehydrating.
