Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a rotating drum in which laundry is placed, and after washing, the laundry is dehydrated and then hot air is sent into the drum to dry the laundry. Regarding type washer/dryers.

In conventional automatic washer/dryers of this type, the laundry in the rotating drum is dehydrated at high speed after washing and then automatically moves to the drying process, so the laundry sticks to the peripheral wall of the drum and hardens during dehydration. The laundry is left to dry for 5 minutes, the laundry becomes wrinkled, it is difficult to take out the laundry after drying, and it takes a long time to dry because the ventilation performance is poor when drying hard laundry. Was.

In order to eliminate this drawback, for example, Japanese Patent Publication No. 39-14565 proposes a method of pouring water onto the laundry stuck to the peripheral wall of the drum during dewatering to cause the laundry to fall.

However, pouring water into laundry that has already been dehydrated results in rewetting the laundry, which has little effect on smoothing out wrinkles when it is subsequently dried. This causes waste and cannot contribute to shortening the drying time.

The present invention was invented with the aim of eliminating wrinkles in the laundry when it is finished drying. It was discovered that cloth with relatively low moisture content is less likely to wrinkle, and this principle is used to prevent laundry from wrinkling.

Another purpose is that if the laundry is sufficiently wet and is squeezed all at once, it may stick to the peripheral wall of the drum and dry without peeling off even when the drum is stopped. The smaller the amount of laundry, the less likely it is that the laundry will stick to the peripheral wall of the drum and fall off during dehydration, so that when moving to the drying process, the laundry will be reliably peeled off without sticking to the peripheral wall of the drum and dry. To provide an automatic washer/dryer that can sometimes unravel laundry and perform drying effectively.

An embodiment for achieving the object of the present invention will be described with reference to the drawings. 1 is a machine frame, and inside the machine frame 1 is a rotating drum 3 supported on a horizontal shaft 2. A water receiving tank 4 is provided outside the drum.

2 and 3 show an electric circuit diagram and a control circuit diagram, 11 is a three-phase power supply, timer cam switches 12, 1
3, 14, 15, 16, and 17 are controlled to open and close by a program timer motor 18, and open and close as shown in the programming diagram in FIG.

40 are provided respectively, and are connected as shown in FIG.
are delay switches, which are instantaneously closed after a predetermined period of time after the delay relays 38, 39, and 40 are activated.

51 indicates a clutch.

Next, to explain the present invention in detail, each cam switch of the timer is set to a predetermined position of the washing process, the laundry is loaded into the rotating drum 3, and the door 52 is closed, the door switch 53 is closed. The cam switch 12, 13.1 is activated.
4 and through the contact E side of the liquid level control switch 19, the water supply valve 20 is operated.

At the same time, the rotating drum 3 is driven in reverse by the low-speed electromagnetic switches 23 and 24.

At this time, the rotating drum 3 sweeps up the laundry in the drum with a baffle provided in the drum and then drops it, transferring it to perform a cleaning action.

At this time, the clutch 51 operates to transmit the rotational force of the low-speed drive motor 5 to the rotating drum 3 via the pulley and belt.

During drainage, the drainage solenoid 21 is activated when the cam switch 13 is switched.

In the first dehydration process after the suji process, the cam switch 14
Since the cam switch 15 is switched to the contact side and the cam switch 15 is switched to the contact side, only the low speed electromagnetic switch 23 is operated and the rotary drum 3 rotates in one direction at a low speed, that is, transfer speed.

At this time, the normally closed switch 45 of the relay 37 and the relay 36
The relay 35 and the delay relay 38 are energized via the normally closed switch 46.

After a predetermined period of time (for example, 10 seconds) has elapsed, the delay switch 48 of the delay IJ relay 8 closes instantaneously, so the relay 3
6 is energized and self-maintained by closing the switch 43, (
At the same time, the relay 35 is demagnetized) Therefore, the delay relay 39 and the medium-speed electromagnetic switch 27 are energized, and the switch 29 is closed, so the rotating drum 3 rotates at a low centrifugal speed of medium speed, and the laundry is transferred to the rotating drum. It is pressed against the circumferential wall by centrifugal force and squeezed slightly.

Furthermore, after a predetermined period of time has elapsed (for example, after 30 seconds), the delay relay 39
The delay switch 49 is closed, the relay 37 is self-held by the switch 44, and the high-speed electromagnetic switch 28 is operated to deliquify the rotating drum 3 at a high centrifugal speed.

In this case, the laundry may stick to the peripheral wall of the drum due to liquid removal, but the laundry will be wetted again in the next scrubbing process and can be easily peeled off.

In the second draining process after the second rinsing process and before the drying process, the cam switch 16 is connected to the contact side for a predetermined period of time (for example, 2 minutes), so there is a delay at medium speed. Even if the delay switch 49 of the relay 39 is instantaneously closed, the high-speed electromagnetic switch 28 is not energized, the relay 37 is energized and self-held by the switch 44, and the third delay relay 40 is energized.

At this time, since the normally closed switch 45 of the relay 37 is opened, the power to the electromagnetic switch 27 is cut off, and therefore the rotating drum 3
rotates freely due to inertia without receiving any driving force, and is finally brought to a stop.

Mechanical brakes make stopping even faster.

The third delay relay 40
When the delay switch 50 is closed and activated, the relay 35 is energized and self-held by the switch 42, and at the same time the delay relay 38 is activated, and from then on, low speed - medium speed - stop - low speed - medium speed stop. It operates repeatedly.

It is difficult to adjust the time required for the delay switch 50 to close due to the action of the third delay relay 40 so that the rotating drum always stops, at least once the rotating drum becomes lower than the transfer speed. Since the laundry stuck to the outer peripheral wall of the rotating drum will fall and be torn off, it is sufficient to reduce the rotation speed from the transfer speed to the point where it stops.

Therefore, the water content of the dehydrated product in the rotating drum is gradually removed, and even if the laundry is then strongly squeezed at a high centrifugal speed, the laundry will not stick to the outer peripheral wall of the rotating drum 3 and fall when it stops.

This means that the drier the wetter the wetter the
This method takes advantage of the fact that it loosens easily even when squeezed hard and rarely hardens.

Next, when the cam switch 16 is connected to the contact a side after a predetermined period of time (for example, 2 minutes after the start of the dehydration process) in order to strongly squeeze the rotating drum 3, the high-speed electromagnetic switch is activated when the relay 37 is energized. 28 is energized and the switch 30 is closed to change the number of poles of the 1 drive motor 6 and drive the rotating drum at a high centrifugal speed.

When the cam switches 14, 15, 16, and 17 are switched, the dehydration process is completed, the drying electromagnetic switch 31 is excited, and the heater 9 and blower motor 32 are energized.

At this time, the rotating drum 3 is rotated at a low swing speed.

When entering this drying process, the laundry reliably falls from the outer circumferential wall of the rotating drum 3, is separated and shaken, and can be dried while minimizing wrinkles.

When the main cam switch 12 is opened, all circuits are cut off and operation is stopped.

Therefore, according to the configuration of the present invention, at the start of the dewatering process before drying, the rotation of the rotating drum is controlled by a low centrifugal speed at which the laundry sticks to the inner peripheral wall of the drum, and a low centrifugal speed at which the laundry sticks to the inner circumferential wall of the drum, and at least a rotation at which the laundry rotates within the drum. Low speeds below the required rolling speed (including stopping) are repeated several times at relatively short intervals, and then the liquid is removed at high centrifugal speeds, which minimizes the wrinkling of the laundry at the end of drying. In addition, when the rotating drum is stopped at the end of the dewatering process before drying, the laundry is loosely squeezed against the inner peripheral wall of the drum, and is not tightly tangled, and can be easily removed from the inner peripheral wall. It can be removed reliably, and there is no need to worry about laundry sticking to the inner periphery of the drum like conventional products, where it dries or gets wrinkled. It can be easily finished and electrically operated reliably, which is of great industrial benefit.
