Abstract

PURPOSE:To improve the durability of a gear mechanism, to decrease the number of one-way clutches and to reduce cost for manufacture by interposing the rotary driving shaft of a driving means, with which an inner tank is revolved around a horizontal axial line or inclined axial line, and a high speed/low speed ratio difference axis gear mechanism between the rotary driving shaft and an orthogonal rotary shaft. CONSTITUTION:By switching a switching mechanism 80, the revolution of an inner tank 30 at the time of washing operation and drying operation and the high speed revolution of a middle tank 21 and inner tank 30 at the time of dehydration can be executed based on the rotation of one motor 51 for tank drive. Especially, since the power transmission from a rotary driving shaft 58 to a rotary shaft 66 is executed by a high speed/low speed ratio pinion 63 and a hypoid gear 68, it is not necessary to separately interpose a deceleration gear mechanism in the rotary driving shaft 58. Accordingly, the number of parts is decreased and work for production and assembly can be easily executed. Further, the power transmission from the rotary driving shaft 58 to the rotary shaft 66 can be smoothly executed and the gear is suppressed to be worn. Then the durability is improved and noise to be generated from a bevel gear or planet gear mechanism can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a drive device for a dehydrating washing machine that can perform washing, rinsing, and dehydrating operations of laundry items.

[Prior Art] Recently, the inventors of this application have invented a dehydrating washing machine as described below. This dehydrating washing machine has an outer tank that can contain water inside the case body, and a support that can rotate around a vertical axis is provided inside the outer tank, and the support can hold the items to be washed. It has a structure in which an inner tank for accommodating the container is rotatably arranged around a horizontal axis.

The items to be washed are washed by rotating the inner tank around the horizontal axis while supplying water to the outer tank so that the water level reaches the inside of the inner tank containing the items to be washed. It has become.

Further, after draining the water in the outer tank, the support body and the inner tank are rotated at high speed around the vertical axis, thereby dewatering the items to be washed.

[Problems to be Solved by the Invention] However, in order to rotate the inner tub in the above-mentioned washing machine, there is a horizontal rotating shaft that supports a drive gear that meshes with a driven gear on the outer periphery of the inner tub, and a vertical shaft that drives this. Although the rotary drive shaft is configured to transmit power through a pair of upper and lower bevel gears, a sufficient reduction ratio cannot be secured between this bevel gear and the driving and driven gears.
The vertical rotary drive shaft must be divided into upper and lower halves and a planetary gear reduction mechanism must be inserted between them, which increases the number of parts and makes manufacturing and assembly laborious. Ta.

Furthermore, since the power transmission of the bevel gear is not smooth, there are problems in that the noise is increased, and the bevel gear is prone to wear and durability is reduced.

Furthermore, at the end of dewatering, the power supply to the drive motor is stopped and a braking force is applied to the shaft supporting the support to stop the support, but the support and the inner tank are rotated around the vertical axis due to inertia. trying to keep spinning. For this reason, the umbrella tII wheel on the horizontal rotation shaft revolves on the lower driving *tIK wheel together with the horizontal rotation shaft. Naturally, there is a risk that the horizontal rotation shaft and the bevel gear thereon that do not follow this revolution rotate, and the inner tank is rotated about the horizontal axis via the driven gear. In other words, the inner tank rotates both horizontally and vertically due to inertia, and the opening for loading and unloading laundry items becomes misaligned with the opening of the washing machine case, which poses a problem in loading and unloading laundry items.

In addition, when washing by horizontal rotation of the inner tank, if a rotational force faster than the rotational force from the drive motor is applied to the inner tank due to items falling into the tank due to the rotation of the inner tank, etc. , the power is reversely transmitted from the internal phase to the motor. Therefore, in this case, the rotation transmission state fluctuates and abnormal noise may occur.

In addition, if the rotation direction of the motor is changed to change the direction of rotation of the inner tank during washing or drying, or if a momentary restraining force is applied to the inner tank due to some reason such as washing glue falling, the support The body may rotate.

In other words, the shaft that supports the support body is a cylindrical shaft through which the bevel gear shaft between the drives is inserted, and braking force is applied to the support shaft when washing or drying, but when changing the rotation direction or momentarily The braking force does not act effectively against instantaneous rotational fluctuations like a restraining force. Therefore, the support shaft rotates together with the support body, and this rotation causes the clutch between the support shaft and the motor to open. There is a risk of abnormal connection and damage. To prevent this, conventionally a one-way clutch has been provided between the case and the support shaft to prevent abnormal rotation of the support shaft, which further increases the number of parts.

An object of the present invention is to prevent as much as possible the phenomenon in which power is reversely transmitted from the inner tank to the motor side when the inner tank is stopped after completion of dewatering, and to stop the inner tank in a predetermined position, which is inconvenient when loading and unloading items to be washed. Reduction gear 8! It is possible to eliminate the need for side panels and one-way clutches, reducing the number of parts and making manufacturing and assembly easier. To provide a drive device for a dehydrating washing machine that can transmit power smoothly, improve the durability of a gear mechanism, reduce noise, and reduce manufacturing costs by eliminating the need for a one-way clutch. be.

[Means for Solving the Problems] The present invention includes an outer tank, a support body rotatably supported in the outer layer around a vertical axis, and a horizontal axis or a predetermined angle with respect to the horizontal axis on the support body. rotatably supported about a tilt axis tilted at.

An inner tank having a large number of small holes in a peripheral wall and capable of accommodating items to be washed; a washing driving means for rotating the inner tank around the horizontal axis or an inclined axis to wash the washing; configured to be able to be connected to and disengaged from the driving means, and to allow rotation of the inner tub about the horizontal axis or the inclined axis when released from the washing driving means;
When connected to a washing drive means, the support body and the inner tank are integrally rotated at high speed around the vertical axis at the same speed and in the same direction, and the relative rotation of the inner tank with respect to the support body is restricted. The washing drive means includes a rotational drive shaft rotatably supported by the outer tank and rotationally driven by a drive motor, and an axis of the rotational drive shaft. A transmission device that is rotatably supported by the support body at a predetermined distance apart across one plane and about an axis that is parallel to the plane and orthogonal to the axis, and that transmits rotation to the inner tank. The rotary shaft is provided with a mechanism, and the rotary shaft and the rotary drive shaft are operatively connected by staggered shaft gears.

[Function] In the dehydrating and washing machine of the present invention, when the washing drive means is operated in a state where the dewatering drive means is separated from the washing drive means, the rotation is smoothly transmitted to the inner tank by the staggered shaft gears. The inner tub is rotated about a horizontal axis or an inclined axis to wash the items stored in the inner tub. At this time, even if a restraining force or the like moves against the inner tank due to some reason, the rotation of the support body is prevented by the action of the staggered gears.

Furthermore, when the washing drive means is operated while the dewatering drive means is connected to the washing drive means, the inner tank does not rotate about the horizontal axis or the tilt axis, but is integrated with the support body. The machine is rotated at high speed around a vertical axis to dehydrate the laundry.

(Operation) Next, dehydrate and dry the tank bottom as described above! ! An overview of the operation of the washing machine will be explained with reference to FIG.

First, with the main body opening/closing W4 and the inner tank lid 37 open, the items to be washed are put into the inner tank 30, then the inner tank lid 37 and the main body opening/closing lid 4 are closed, and a start switch (not shown) is operated. , under the control of the control circuit 111, the series of operations shown in the time chart of FIG. 6 are automatically performed sequentially as follows.

(a) Water supply operation by the water supply device 81 (b) Washing operation based on the rotation of the inner tank 30 that rises to the washing drive means 76 (c) Drainage operation by opening the drain valve 85 (d)
Dewatering operation based on the rotation of the inner tank 21 by the dewatering drive means 77 (e) Water supply operation by the water supply device 81 (f) Water supply by the water supply device 81 and rinsing operation based on the rotation of the inner tank 30 by the washing drive means 76 (g ) Drainage operation by opening the drain valve 85 (h)
Dewatering operation 5 based on the rotation of the inner tank 21 by the dewatering drive means 77 (i) Drying operation based on the warm air supply by the hot air supply device 94 and the rotation of the inner tank 30 by the washing drive means 76 Note that each of the above operations Between (a) and (1), the stop positioning of the middle tank 21 or the inner tank 30 is performed by the control circuit 111 based on a detection signal from a sensor (not shown).

Next, each of the above operations will be explained in detail.

Now, when washing is to be carried out with the items to be washed stored in the inside 30, the drain valve 85 is closed, the spring clutch 71 is disengaged, and the washing driving means 76 is formed. The brake body 75 enters a braking state and the rotation of the inner tank 21 is regulated. In this state, the water supply device 81
The water supply valve is opened, and water is supplied into the outer tank 15 from the water supply port 82. When the water level in the outer tank 15 reaches the inside of the inner tank 30 and reaches the normal water level Wn, the phase drive motor 51 is rotated, and the washing drive means 76 drives the inner WJ.
30 is rotated at a reduced speed around the horizontal axis X-X to begin the washing operation.

During this washing operation, the spherical inner tank 30 containing the items to be washed is rotated around the horizontal axis @X-X, and with the rotation, the items to be washed are rolled by the plurality of reversing protrusions 3440, etc. At the same time, so-called washing is performed. Therefore, the amount of water used when washing is small, and since the items to be washed are hardly twisted or tangled, the washing operation can be carried out effectively without causing any damage to the items to be washed. After the operation is finished, the washing operation can automatically shift to the draining operation and the dewatering operation without requiring the troublesome work of correcting twists and entanglements of the items to be washed.

In addition, when rinsing is performed after washing items,
As in the case of washing, the inner tank 30 is rotated by the phase drive motor 51 via the washing drive means 76. Further, when the water supply valve of the water supply device 81 is opened, water is supplied from the first water supply port 82 toward the outer peripheral upper surface of the inner tank 30, and the rinsing water in the outer tank 15 passes through the overflow port and overflow hose 87 (not shown). The water level is maintained at a constant level. Therefore, while the rinsing water is replaced one after another, the water from the water supply port 82 effectively washes away the foam adhering to the outer peripheral surface of the inner tank a30 and the foam adhering to the items to be washed in the inner tank 30. .

Furthermore, when dewatering is performed after the washing and rinsing of the laundry, the spring clutch 71 is brought into a continuous state to form a dewatering driving means 77, and the brake body 7
5 is placed in a non-braking state, and rotation of the inner tank 21 is allowed.

When the phase drive motor 51 is rotated in this state, the rotary drive shaft 58 and the upper and lower hollow shafts 24.54 are rotated together,
Therefore, the inner tank 21 and the inner tank 3 are moved by the dewatering drive means 77 while the inner tank 21 is kept fixed to the inner tank 21.
0 are integrally rotated at high speed around the vertical axis MY-Y, and the laundry is dehydrated. Therefore, the rotational axis of the inner tank 30 containing the items to be washed is changed from the horizontal axis X-X to the vertical axis Y-Y during the transition from the washing or rinsing operation to the dewatering operation without changing the attitude of the tank. This allows the process to be carried out smoothly and in a short period of time. During this dehydration, the inner tank 30 is not rotated by the rotary drive shaft 58 through the meshing of the drive gear 69 and the driven gear 44, so the inner tank 30 does not move by itself. Therefore, for example, as shown in FIG. As shown, if the center of weight B of the items to be washed in the inner tank 30 is off the vertical 1!41 line Y-Y,
A centrifugal force acts on the item to be washed in the direction in which it came off, and the inner tank 30 rotates as shown by arrow A, and the item to be washed moves to ff1l.
tffll, resulting in imbalance and large vibrations, but as mentioned above,
This kind of thing can be prevented because 130's erratic movements are prevented.

In addition, when drying is performed after the dehydration of the items to be washed, the inner tank 3 is
0 is rotated around the horizontal axis X-X, and the fan motor 96 and heating heater 98 are energized to generate warm air from the hot air source 95 of the hot air supply device 94. Connecting cylinder 100, hot air supply passage 99, air outlet 1
01 and the rear shaft portion 31 into the inner tank 30, and is discharged from each small hole 35. Therefore, while transferring the items to be washed, hot air can be applied to the items to be washed to effectively dry the items.

During this drying operation, the hot and humid air in the inner tank 830 flows from the overflow port (not shown) provided in the outer tank 15 which also serves as a hot air exhaust port, through the overflow hose 87, and into the expansion cooling chamber 8.
After being cooled and dehumidified in the overflow hose 87, expansion cooling chamber 88, etc., it is discharged to the outside through the drainage hose 86. Therefore, the hot and humid air in the inner tank 30 is not directly discharged to the outside.

Note that the reduction ratio of the gear transmission system of this example is as follows. The rotation speed of the motor 51 is 1800 rpm, which is reduced to 900 rpm between the pulleys 53 and 61.
Next, hypoid 1i1 car 63°68, 1/5 of 18
The speed is reduced to 0 rpm, and the gear speed is reduced to 1/6 at 69.44.
The speed is reduced to 30 rpm.

As mentioned above, in the dehydrating/drying/washing machine of this embodiment, the switching f! By switching the canopy 80, the rotation of the inner tank M30 during the washing operation and the drying operation and the high-speed rotation of the middle WI 21 and the inner tank 30 during the dehydration operation can be changed to 1.
This can be accomplished based on the rotation of the two phase motors 51.

In particular, in the embodiment described above, power transmission from the rotary drive shaft 58 to the rotary shaft 66 is performed by the high reduction ratio binion 63 and the hypoid gear 68;
8 does not require a separate reduction gear mechanism, therefore,
By reducing the number of parts, manufacturing and assembly operations can be easily performed.

Furthermore, power can be smoothly transmitted from the rotary drive shaft 58 to the rotary shaft 66, suppressing gear wear and improving durability, and reducing noise generated from bevel gears and the top of the planetary TK vehicle machine. I can do it. Furthermore, since the binion 63 can be formed integrally with the rotary drive shaft 58, manufacturing and assembly can be easily performed from this point as well.

Furthermore, even if the inner tank 21 and the inner tank 30 try to continue rotating around the vertical axis due to inertia at the end of dewatering, the hypoid gear 68 does not revolve on the binion 58. Because their axes are at odds with each other, as is clear from FIG. Moreover, since it has a high reduction ratio, the hypoid gear 68
As a result, the rotation (rotation) of the hypoid gear 68 is prevented, and the revolution around the vertical axis YY is also prevented.
f! Rotation about the vertical axis of I21 and In [30 is prevented. Therefore, misalignment between the washing article openings of the inner tub 30 and the middle tub 21 and the opening of the washing machine case can be almost prevented. Even if a positional shift occurs, the shift can be made small, so correction can be easily carried out in a short time.

In addition, when washing by horizontal rotation of the inner tank, if a rotational force faster than the rotational force from the drive motor is applied to the inner phase due to the falling of the items to be washed in the tank due to the rotation of the inner tank, etc. , the power is going to be reversely transmitted from the inner tank to the motor, but this reverse transmission is a hypoid gear! ! Since this is prevented by the ellipse, the rotation transmission state does not fluctuate and abnormal noises are not generated.

In addition, when the rotation direction of the motor is changed to change the rotation direction of the inner tank during washing or drying, or when a momentary restraining force is applied to the inner tank due to some reason such as washing glue falling, Even if the braking force from the brake device does not work effectively, there is no risk that the middle m21 will rotate.

That is, since the hypoid gear 68 cannot revolve on the pinion 63, the hollow shaft 24,54 supporting the inner tank 21 does not rotate, and therefore, there is no possibility that the spring clutch 71 will be connected abnormally.

Therefore, it is possible to eliminate the one-way clutch that prevents abnormal rotation of the hollow shaft 24.54, and the number of parts can be reduced.

[Modification] Note that the present invention is not limited to the configuration of the embodiment described above7, but can be modified and embodied as follows.

<1> The inner tank 21 is formed into a substantially cylindrical shape using a wire mesh or the like, and the mesh on the peripheral wall is used as a drainage part, or a plurality of columns are combined to form a substantially cylindrical framework, and the gap between each column is Alternatively, a stainless steel plate or the like may be formed into a cylindrical shape with a bottom, and a drain hole may be provided through the peripheral wall and bottom wall.

(2) The inner tank 30 is rotatably supported around an inclined axis inclined at a predetermined angle with respect to the horizontal II#i line XX.

(3) using a worm instead of the binion 63 and a worm wheel instead of the hypoid gear 68;
In this case as well, the same effect as in the previous embodiment can be obtained.

[Effects of the Invention] As explained above, the present invention provides a high reduction ratio between the rotary drive shaft of the drive means for rotating the inner tank around the horizontal axis or the inclined axis and the rotary shaft orthogonal thereto. Since a gear mechanism with staggered shafts is installed, there is no need to provide a separate reduction gear on the rotary drive shaft, and a one-way clutch is used to prevent reverse rotation of the inner tank. l It is also possible to omit the treetop, thus reducing the number of parts, making manufacturing and assembly easier, and allowing smooth power transmission from the rotary drive shaft to the rotary shaft. , improve the durability of gears,
Noise generated from the bevel gear and the reduction gear m structure can be reduced. In addition, this invention prevents as much as possible the phenomenon in which power is reversely transmitted from the inner tank to the motor side when the inner tank is stopped after completion of dewatering, etc., and stops the inner tank in a predetermined position. This has an excellent effect in that the entrances and exits of the baths can be easily aligned and there is no problem in putting in and taking out the items to be washed.
