Abstract

PURPOSE:To surely prevent an inner basket from rotating with an excessive vibration during start-up period by a method wherein the inner basket is stopped at a position where two laundry turning-over protruding ribs among two or more of them are located below the rotating axial line of the inner basket and arranged symmetrically to the right and left sides across a vertical plane intersecting the rotating axial line. CONSTITUTION:Washing or laundry is carried out by rotating an inner basket 33 around a horizontal axial line X-X. Dewatering is performed by spinning the inner basket, in which the washed laundry is held, around a vertical axial line Y-Y at high speed together with a support 21. Further, the inner basket 33 is stopped at a position where at least two laundry turning-over protruding ribs 38 among two or more of them are located below the rotating axial line of the inner basket 33 and arranged symmetrically to the left and right sides across a vertical plane intersecting the rotating axial line, so that the laundry in the inner basket is restricted to move up beyond the two symmetric protruding ribs 38. Therefore, the support 21 and the inner basket 33 are prevented from rotating with an excessive vibration during high speed spinning in dewatering operation because unbalanced loading of the laundry is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dehydrating washing machine capable of washing and dehydrating items to be washed.

[Prior Art] Conventionally, the following two types of washing machines have been known as typical configurations.

The first type consists of an aquarium, a dehydration tank supported rotatably around a vertical axis within the aquarium, and a dehydration tank with a number of small holes perforated in the surrounding wall, and a dehydration tank rotatably supported around a vertical axis within the dehydration tank. Equipped with rotatably supported stirring blades, by rotation of the stirring blades,
This dehydrating washing machine not only washes the items to be washed, but also dehydrates the items after washing by rotating the dehydrating tank at high speed.

The second type includes an aquarium and a rotating drum that is rotatably supported around a horizontal axis within the aquarium and has a large number of small holes in its peripheral wall, and contains water in the aquarium. This is a washing machine that washes the items to be washed in the rotating drum by rotating the rotating drum with Since the items to be washed are submerged and then stirred by a stirring blade and washed by a stream of water, a large amount of water is required for washing, and in addition, the washing action can cause the items to be washed to become twisted or tangled. If this twisting and entanglement of the items to be washed is not corrected after the washing operation is completed, the center of gravity of the dehydration tank will be unbalanced and the dehydration operation will not be performed smoothly, making it impossible to perform the washing and dehydration operations continuously. Something happened.

In addition, in the second type, washing is performed by rotating the rotating drum around the horizontal axis and transferring the items to be washed without depending on the water flow, so compared to the first type, The amount of water used when washing is reduced, and the items to be washed are no longer twisted or tangled. However, with this second type, at the end of the washing operation, the object to be washed is unevenly distributed at the bottom of the rotating drum due to its own flow rate, causing the center of gravity of the rotating drum to be unbalanced, so it continues to rotate in this state. It was not possible to perform a dewatering operation by rotating the drum at high speed around a horizontal axis. For this reason, this type of washing machine that performs dehydration uses a large weight such as a flywheel to suppress vibrations. Therefore, this type of washing machine was heavy and unsuitable for household use.

This invention was made by paying attention to the problems that exist in the conventional technology, and its purpose is to wash the items without twisting, tangling, or fabric damage. The objective is to provide a machine that can perform the following steps continuously and effectively without dehydration and washing.

Furthermore, it is an object of the present invention to always stop the inner tank for accommodating the items to be washed at a predetermined position at the end of the washing operation, so that the items to be washed in the inner tank are not shifted to one side during spin-drying. It can be arranged in an average manner,
To provide a dehydrating washing machine capable of smoothly starting dehydrating operation without excessive vibration.

[Means for Solving the Problem] In order to achieve the above object, the dehydration washing machine of the present invention includes an outer tank, a support body rotatably supported around a vertical axis within the outer tank, The support body includes an inner tank rotatably supported around a horizontal axis or an inclined axis tilted at a predetermined angle with respect to the horizontal axis, and an inner tank having a large number of small holes in the peripheral wall, and a water level that reaches the interior of the inner tank. a washing driving means for washing by rotating the inner tank around the horizontal axis or the inclined axis with water contained in the outer tank and items to be washed stored in the inner tank; a dewatering drive means for dewatering by rotating the support body integrally with the inner tank at high speed around the vertical axis while the items to be washed after being washed are housed in the inner tank; is equipped with multiple protrusions for reversing the items to be washed, and at the end of the washing operation,
A setting for stopping the rotation of the inner tank in a state in which at least two of the plurality of protrusions are arranged below the rotation axis of the inner tank and symmetrically with respect to a vertical plane passing through the rotation axis. It is equipped with position stopping means.

[Function] In the dehydrating washing machine configured as described above, water is stored in the outer tank and objects to be washed are stored in the inner tank, and the inner tank rotates around the horizontal axis or the inclined axis. The washing machine is rotated by the machine to wash the items to be washed. Further, with the items to be washed stored in the inner tank, the support body is rotated at high speed around a vertical axis integrally with the inner tank to dehydrate the items to be washed.

Furthermore, in this dehydrating washing machine, at the end of the washing operation, at least two of the plurality of protrusions for reversing the washing object are arranged below the rotational axis of the inner tank in a vertical plane passing through the rotational axis. On the other hand, in the symmetrically arranged state, the rotation of the inner tub is stopped, and the upward movement of the items to be washed in the inner tub is restricted by the two symmetrically positioned protrusions. Therefore, uneven distribution of some of the clothes is prevented during high-speed rotation during the dewatering operation, and the support and the inner tub are not rotated with excessive vibration.

Later, the locked state of the main body opening/closing fi4 is confirmed by the lid lock switch 105, and when it is not in the locked state, the solenoid 10 is turned off and then returns to the above-mentioned stellar 731 (steps S3 and S4), and when it is in the locked state, The operating state of the lid switch 104 is confirmed again, and if it is not in the operating state, the process returns to step S1 (step S5). Therefore, the closed state of the main body opening/closing lid 4 is double confirmed by both the switches 104 and 105. become.

After the operating state of the lid switch 104 is reconfirmed, the lid sensor 106 checks whether the inner tank lid 42 is in the closed position, and the locking member 47 locks the tank lid 42 in the closed position. If the fi body 42 is not completely locked in the closed position, the action proceeds to the next step (step S6). If it is opened to the point where it touches Tt, the open state is detected by the beneficial body sensor 106, and an abnormality is displayed by operating the piezoelectric buzzer 136 or the like (step S7).

Therefore, the washing operation is not started when the inner tank lid 42 is not completely locked in the closed position, and the lid 42 is opened as the inner tank 33 rotates during the washing operation. The beneficial body 42 collides with the inner surface of the middle W421 and the beneficial body 42
It is possible to reliably prevent the risk of damage to the inner tank 33 or its surroundings, or the objects to be washed flying out from inside the inner tank 33.

After the Bodhisattva closure confirmation operation, the water supply device 83 performs a water supply operation to start the washing operation, but during this washing operation, the drain valve and the clutch solenoid 90 are turned off, and the spring clutch 74 is turned off. The first driving machine side 79 is formed in the cut-off state, and the brake body 78 is in the braking state to restrict the rotation of the inner tank 21.

In this state, the seed part drive motor 55 is rotated, and the first drive motor #! The inner tub 33 is rotated around the horizontal axis X-X through the 7 rotors, and the items to be washed are transferred by the plurality of reversing ridges 38, 46, 54, and washing is performed in a so-called tumble washing process.

Therefore, compared to a method in which the items to be washed are stirred with water using a pulsator, etc., the amount of water used during washing can be reduced, and there is almost no twisting or entanglement of the items to be washed during the washing operation, so there is little chance of fabric damage. It is possible to perform the washing motion effectively without causing any problems, and furthermore, there is no need for the troublesome work of correcting twists and entanglements of the items to be washed after the washing motion is completed, and the washing motion can be changed from the washing motion to the draining motion and the spin-drying motion. Can be migrated automatically.

(Operation of Stopping the Inner Tank in a Fixed Position) Next, the operation of stopping the inner tank 33 in a fixed position at the end of the washing and drying operations will be described in detail according to the flowchart of FIG. 11.

Now, at the end of washing and drying operations, etc., when the seed section driving motor 55 is stopped and the inner tank 33 is stopped after inertial rotation, a predetermined period of time in anticipation of the end of the inertial rotation (
After about 2 seconds), the motor 55 is rotated forward and inching by turning on and off the triax 128 on the main winding 55a side at predetermined intervals (for example, 0.1 seconds on and 2 seconds off).
The inner tank 33 is rotated in small increments at a low speed (steps S1 and S2). In this rotating state, the inner tank position sensor 111 detects the magnet 110, and when a detection signal is input, the auxiliary winding By the reverse half-wave operation of the motor 55 based on the intermittent ON of the triac 129 of 55 bflll, the inner tank 33 is slightly rotated in the opposite direction at a very low speed to correct the overrun (steps S3 and 34).

In this rotating state, the magnet 11 is detected by the inner tank position sensor 111.
0 detection operation is performed and a detection signal is input, the motor 55 is stopped and the rotation of the inner tank 33 is stopped (steps S5 and S6). > When the detection operation of the inner tank position sensor 111 is performed again at f& and a detection signal is input,
Assuming that the inner tank 33 has been stopped at a predetermined position, the process moves on to the next step (step 7).

If the detection signal is not input during the re-detection operation of the position sensor 111, that is, if the inner tub 33 rotates after the motor stops due to uneven distribution of laundry items, etc., the main winding 55
Motor 5 based on intermittent ON of triac 128 on side a
5, the inner tank 49133 is rotated in the forward direction at a very low speed (step S8). In this rotating state, the detection operation of the inner tank position sensor 111 is performed and a detection signal is input. , the motor 55 is stopped and the rotation of the inner tank 33 is stopped (steps S9 and 310).

After a predetermined time (approximately 1 second) after the motor stops,
The detection operation of the inner tank position sensor 111 is performed again, and if a detection signal is input, it is assumed that the inner tank 33 has been stopped at a predetermined position, and the process moves to the next step (step 11).

By the way, when the inner tank 33 is stopped at the fixed position,
As shown in FIG. 2, the two washing object reversing protrusions 38 on the inner circumferential surface of the inner tub 33 are located below the rotational axes X and -X of the inner tub 33 on a vertical plane passing through the rotational axis X-X. It is arranged symmetrically with respect to the left and right sides.

Therefore, when the washing operation or the rinsing operation is completed and the transition is made to the dewatering operation, the objects to be washed in the inner tank 33 are prevented from moving upward between the two protrusions 38 by the protrusions 38. The inner tub 21 and the inner tub 33 are arranged evenly on the inner bottom of the spherical inner tub 33, and due to the unbalance of the items to be washed, the inner tub 21 and the inner tub 33 are Excessive vibration rotation can be prevented.

Further, when the inner tank 33 is stopped at the fixed position, the first
As shown in the drawings and FIG. 7, the lid 42 of the inner tank 33 is placed in a position that matches the opening 17 of the outer tank cover 16.

Therefore, at the end of the drying operation, etc., after opening the main body opening/closing lid 4, the inner M4 base body lid can be opened without any hindrance through the opening 17, and the items to be washed in the inner tank 33 can be easily removed. You can take it out or put other items in it to be washed.

When dewatering is to be performed after the washing operation is completed, the drain valve and the clutch solenoid 90 are turned on, the spring clutch 74 is connected, and the second driving machine #I80 is formed. , the brake body 78 enters the non-braking state and rotation of the inner tank 21 is allowed. In this state, the seed part driving motor 55 is rotated forward by the conduction of the triac 128 on the main winding 55a side, and the inner tank 21 is integrally moved along the vertical axis Y-Y with the inner tank 33 via the second drive side 80. It rotates at high speed around the machine to dehydrate the items being washed. Therefore, the rotational axis of the inner tank 33 containing the items to be washed can be changed from the horizontal axis
By changing to -Y, it can be done smoothly in a short time.

(Operation of Stopping the Inner Tank in a Fixed Position) Next, the operation of stopping the inner tank 21 in a fixed position at the end of the dewatering operation will be described in detail according to the flowchart of FIG. 12.

Now, at the end of the dewatering operation, etc., the seed part movement motor 5
5 is stopped and the inertial rotation speed of the intermediate tank 21 becomes low.
After a predetermined period of time in anticipation of the decrease in rotation, the drain valve and clutch solenoid 90 are turned off, and the brake body 78
enters the braking state, and the rotation of the inner tank 21 is stopped by braking (
In steps Sl and S2), in this state, the inner tank position sensor 109 detects the magnet 108, and if a detection signal is not input within a predetermined time (about 1 second), the inner tank 21 is stopped. By turning on the solenoid 90, the brake body 78 is switched to a non-braking state (steps S3 and S4).

After that, the triac 128 on the main winding 55a side is turned on and off at predetermined time intervals (for example, 0.1 seconds on, 2 seconds off).
As a result, the motor 55 is operated in normal rotation, and the intermediate tank 2
1 is rotated in small increments at a low speed (step S5). In this rotating state, the detection operation of the middle tank position sensor 109 is performed,
When the detection signal is input, the solenoid 90 is turned off, the brake body 78 enters a braking state, and the rotation of the inner tank 21 is stopped by braking (steps s6 and s7).

In this stopped state, the middle tank position sensor 109
If the detection operation is performed and the intermediate tank 21 is stopped at a predetermined position, the process moves to the next process operation, and if it is not stopped at a predetermined position, the process returns to step S3 and the above-mentioned predetermined process is performed. The position stop operation is repeated (Stella 7S8).

By the way, in this embodiment, the magnet 108 as the object to be detected is provided on the balancer 22 so as to be located near the installed radial position of the inner tank 21, that is, at the part where the rotation angle is the smallest with respect to the amount of rotation. Therefore, the position sensor 109
Based on the sensing of the magnet 108 by the magnet 108, the position of the inner tank 21 is accurately detected with almost no error, and the inner tank 21 is accurately stopped at a predetermined position. When the inner tank 21 is stopped in its fixed position, the inner tank 21 doubles as an air outlet, as shown in FIG. The rear bearing part 30 of s21 and the rear shaft part 34 of the inner tank 33 are arranged in a position that matches the air outlet 101 of the outer part 4115. Therefore, at the end of the dewatering operation, the hot air supply device 95 is connected to the inside of the inner tank 33 via the air passage 99, the air outlet 101, the rear bearing section 30, and the rear shaft section 34, and in this state. A smooth transition to drying operation is possible.

(Other operations) Next, the rinsing operation and drying operation of the object to be washed will be described in detail.

First, when rinsing is performed after washing the items to be washed, the lateral drive motor 55 moves the inner i! 833 is the horizontal axis x-
While being rotated around X, the water supply valve 8 of the water supply device 83
4 is opened, water is supplied from the first water supply port 85 toward the outer peripheral surface of the inner tank 33, and at the same time, water is supplied from the second water supply port 86 to the ventilation ventilation F! @99, water is supplied to the inside of the inner tank 33 through the air outlet 101 and the rear shaft part 34, and the rinsing water in the outer tank 15 is discharged from a drainage channel (not shown) of an overflow port (not shown). Water level is maintained constant. Therefore, the rinsing water is replaced one after another, and the bubbles adhering to the outer circumferential surface of the inner tank 33 are gently washed away along the spherical outer circumferential surface by the water from the first water supply port 85, and the inside of the inner tank 33 is Foam adhering to the item to be washed is effectively washed away by water from the second water supply port 86.

Furthermore, if the laundry is dried after dehydration,
As in the case of washing, the horizontal drive motor 55 causes the first
Inside via 7 drive mechanisms! 1133 is rotated around the horizontal axis X-X, and the fan motor 96 and the heating heater 98 are energized, so that the hot air generated from the hot air supply bag 'IL95 is connected in a visible bellows-like manner. Cylindrical body 100, ventilation passage 99, ventilation port 101, and rear shaft portion 34
The water is supplied into the inner tank 33 through the holes 40 and discharged from each small hole 40 . Therefore, as the inner tank 33 rotates, the items to be washed are transferred and the drying operation can be carried out effectively.

During this drying operation, the high-temperature and humid air in the inner tank 33 is transferred to the rear shaft portion 34 of the inner tank 33, which also serves as an air outlet.
On the opposite side, the water is discharged into the overflow hose 91 from an overflow port (not shown) that also serves as a hot air exhaust port formed in the side wall of the outer tank 11.5, and is further discharged to the outside via the drain hose 89. The hot and humid air is cooled and dehumidified in the overflow hose 91, expansion cooling chamber 92, and eight drainage hoses.

(4) In the embodiment described above, three reinforcing annular protrusions are formed on the outer peripheral surface of the inner tank 33. Formed on the inner peripheral surface of Pi33.

When the annular protrusion 39 is formed on the inner circumferential surface of the inner tub 33 in this way, compared to the case where it is formed on the outer circumferential surface, when the inner tub 33 rotates during a rinsing operation, the annular protrusion 39 It is possible to suppress the generation of bubbles due to agitation of water, and also prevent the items to be washed from coming into close contact with the inner peripheral surface of the inner tank 33 during drying, so that drying can be carried out effectively. It can be carried out.

(5) In the embodiment described above, when the intermediate tank 21 is stopped at a fixed position, the fixed position is detected while rotating the inner tank 21 at a low speed by the inching operation of the seed part movement motor 55. 55 to perform fixed position detection while rotating the intermediate tank 21 at a very low speed.

(6) In the above embodiment, a total of three protrusions 38, 46 and partial protrusions 54 for reversing the laundry are provided at 120 degree intervals, but for example, in the stopped state shown in FIG.

[Effects of the Invention] This invention has the following features:
It has the following effects.

The support body is supported within the outer tank so as to be rotatable around a vertical axis, and the inner tank is supported within the support body so as to be rotatable around a horizontal axis or an inclined axis, and the rotation axes of the support body and the inner tank can be selectively used. Since the washing machine is configured to perform washing and dewatering operations, the washing, rinsing, and dewatering operations can be performed continuously. In addition, the items to be washed can be washed without using swirling water currents, so the amount of water used during washing can be reduced, and the items to be washed are almost never twisted or tangled during the washing operation, resulting in fabric damage. The washing operation can be performed effectively with almost no problems, and after the washing operation is finished, there is no need for the troublesome work of correcting twists and entanglements of the items to be washed, and the washing operation automatically shifts to the dehydration operation. can do.

Further, at the end of the washing operation, etc., at least two of the plurality of protrusions for reversing the items to be washed are arranged below the rotation axis of the inner tub and symmetrically with respect to a vertical plane passing through the rotation axis. Since the rotation of the inner tank is stopped in this state, the items to be washed in the inner tank are arranged evenly and unevenly at the inner bottom of the inner tank by the two protrusions during dewatering operation that involves high-speed rotation. At the same time, the upward drive is restricted, and it is possible to reliably prevent the support body and the inner tank from rotating due to excessive vibrations at the start of the dewatering operation.
