Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehydrator having a single row structure for rinsing and dewatering, and more particularly to a dehydrator having a single row structure for rinsing and dewatering, and more particularly to a dehydrator whose purpose is to improve the rinsing efficiency.

In recent years, various dehydrators of this kind have been devised for the purpose of saving water and energy. Generally, water is supplied to the tank for rinsing.

However, in such conventional dehydrators, the water supplied to the laundry at the bottom of the tub does not penetrate the laundry sufficiently and is immediately discharged through the dehydration hole, making it difficult to rinse thoroughly. There are very few flaws that cannot be avoided.

Therefore, in view of the conventional situation as described above, the present invention has been devised to supply water into the dehydration tank during the inertial operation of the dehydration tank, which is performed when the dehydration operation is stopped at predetermined intervals by rotating the dehydration tank. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4, which provides a dehydrator that efficiently rinses laundry when water is supplied.

In FIG. 1, reference numeral 1 denotes a dehydration tank with a large number of dehydration holes 1 provided at the lower end of the peripheral wall, and the peripheral wall is formed into a generally cylindrical shape that tapers from the top to the bottom. 3 is arranged around the lower end of the peripheral wall of the dehydration tank 1 so as to surround the dehydration hole 2. It is formed into a substantially tapered cylindrical shape and is fixedly attached to the dehydration tank 1 with a set screw 4. ing.

Reference numeral 5 denotes an electric motor for driving the dehydrator, that is, as a rotating device for rotating the dehydrator, which is supported by the vibration-proof spring 6, and its drive shaft 51& is fixed to the bottom wall of the outer tank 3 and is substantially connected to the dehydrator 1. ing. This electric motor 5 is connected to a motor operating circuit which will be described later.

T is a drainage tank that covers one circumference of the dehydration tank, and 8 drainage ports are provided at the bottom. S is the opening 1 on the top of the dehydrator main body 15.
It is an opening/closing lid that covers 5a, and one end is rotatably supported by the main body 15# so that it can be opened and closed freely, and on the back side there is a water channel that supplies water from the top opening 15 into the dehydration tank 1. 10
is provided, and water supplied from 14 water supply hoses is guided to the water channel 10.
.

Reference numeral 11 denotes a water supply valve as a normally closed water supply device installed in the water supply hose 14, which is connected to a water supply valve operating circuit to be described later and is opened when electricity is applied.

12 turns on a lid switching circuit that operates in conjunction with the opening/closing lid 9.

Reference numeral 13 denotes an automatic timer serving as a control device for sequentially performing rinsing and dehydration, which will be described in detail later.

The dehydrator includes the rotating device, a switching device for switching the drive of the water supply device, and a control device for controlling the operation of the switching device so that the switching operation is performed at predetermined time intervals. , will be equipped.

That is, FIG. 2 shows the operating circuit of the dehydrator, and 15 is the power supply.

Then, the lid switch 1 is connected to the power source 15 of the circuit.
2 and the main switch 1T of the circuit of the automatic timer 13 are connected in series, and the drive motor 18 of the automatic timer 13 and the changeover switch 1 as the switching device 9 are connected in parallel. This changeover switch 19 is for switching between the motor operating circuit 20 connected in series and the water supply valve operating circuit 21 connected in parallel to this circuit 20 with respect to the foreboard power supply 15. The terminal a connected to the water supply valve operating circuit 20 and the terminal A connected to the water supply valve operating circuit 21 are selectively closed.

The automatic timer 13 is driven by a drive motor 18, and the changeover switch 19 is configured to alternately switch between the motor operating circuit 20 and the water supply valve operating circuit 21 at predetermined time intervals during the rinsing process. , the operation of the changeover switch 19 is controlled to switch over to the motor operating circuit 20 within a certain period of time during the dehydration process after the completion of the rinsing process, and the control is performed as shown in the operating mode diagram shown in FIG. .

Next, the operation of this dehydrator will be explained.

First, the laundry to be rinsed is put into the dehydration tank 1, the opening/closing lid s'6 is closed, and then the automatic timer 13 is set to the rinsing process, and the main switch 17 is closed as shown in the operation mode diagram. At the same time, the changeover switch 1g is closed to the a terminal side. At this point, the lid switch 12 is also closed, so the drive motor 18 is energized, the timer 13 is driven, and the dehydration tank driving electric motor 5 is driven to rotate the dehydration tank 1 and start dewatering operation. Therefore,
The detergent liquid contained in the laundry flows down the inner a wall of the dehydration tank 1 due to centrifugal force and is directed downward from the dehydration hole 2 to the outer tank 3.
The water is moved to the upper part of the outer tank 3 and discharged into the drainage tank 1 by centrifugal force.

In this way, the detergent liquid contained in the laundry is dehydrated, and when a predetermined time has elapsed, the automatic timer 13 switches to the selector switch 191-b terminal according to the operation mode diagram shown in FIG. The power to the dehydration tank driving motor 5 is cut off, and the water supply valve 11 is now powered.

Therefore, the water supply valve 11 is opened, the water supply hose 14 is opened, and water from a water supply source (not shown) is guided to the water supply channel 10.
Water is supplied into the dehydration tank 1 from here.

Here, the inertial operation of one dehydration tank continues after the rotational drive is stopped, and the centrifugal force generated by this causes water to be supplied and the nine bottles are forcibly guided to the inner bottom of the dehydration tank 1.

After that, 10 revolutions of the dehydration tank gradually decrease, and when the rotation stops, the water in the dehydration tank 1 and the outer tank 3 loses centrifugal force, so the laundry at the center bottom of each of them is the least likely to get wet. Furthermore, since the water supply continues, the laundry is sufficiently rinsed and water is supplied, and when the preset time for water to overflow from the outer tub 3 is reached, the automatic timer 13 starts as shown in Figure 3. As shown in the operation mode diagram shown in FIG. 1, the selector switch I B'a is again switched to the terminal side, so that the dehydration tank driving electric aS rotates, the water supply valve 11 is closed, and dehydration operation resumes.

As described above, when the rinsing process for a predetermined period of time for the laundry, in which the spin-drying and rinsing operations are repeated and alternately completed, the automatic timer 13 switches the changeover switch 11 to the a terminal side, and the operation mode diagram When the laundry is dehydrated for a predetermined time and the scheduled time is reached, the main switch 17 of the automatic timer 13 is opened and the operation of the dehydrator itself is stopped and the rinsing and dewatering power (completed) is reached. It shows the number of rotations of Dehydration!1 versus time.

According to the above explanation, the rinse water supplied into the dehydration tank 1 during inertial operation of the dehydration tank 1 is forcibly guided to the inner bottom of the dehydration tank 1 by the weak centrifugal force generated by the rotation of the dehydration tank 1. Water can be sufficiently supplied even to the laundry at the center of the bottom where WK water is difficult to be supplied in the dewatering tank 1, and the laundry can be rinsed efficiently.

As explained above, according to the present invention, the dehydration tank 411 is operated for a predetermined time and then stopped, and the process of repeatedly supplying water during the subsequent inertia operation of the dehydration tank is repeated. The laundry can be sufficiently watered and rinsed efficiently without light.
