Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention manually operates each of the washing, rinsing, and dehydrating steps.
The present invention relates to a single-tank washing machine that is simple and convenient to carry.

[Background of the invention]

Conventional single-tank washing machines cannot wash, rinse, or spin water.

[Purpose of the invention]

The present invention provides a system in which washing, rinsing, and dehydration can be controlled manually.

[Summary of the invention]

The rotating washing tub has a forward and reverse rotation inside the washing tub, and a rotating washing tub that rotates in one direction is provided with a speed reduction mechanism that changes the rotation speed between forward and reverse rotation and reverse rotation.

[Embodiments of the invention]

“Embodiments of the present invention will be described below in detail based on the drawings.As shown in FIG. 1, a washing tub 2 is provided inside an outer frame 1. A tank 3 is provided.

The electric motor 4 is attached to the lower part of the outer frame 1.

A cooling 7/6 is attached to the rotating shaft 5 of the electric motor 4. A shaft joint 7 is formed in the cooling fan 6. A rotating shaft 9 hanging downward from a clutch portion 8 provided on the lower surface of the bottom of the washing tub 2 is fitted into a shaft coupling 7 and fixed. A rotating shaft 10 rising upward from the clutch portion 8 is fixed to the rotating washing tub 3. A drain hole 11 is provided at the bottom of the washing tub 2. Drain hose 1 to this drain hole 11
2 is installed.

The rotating washing tub 3 does not have small holes for water passage formed in the side wall.

A plurality of stirring blades 13 are formed on the outer periphery of this. This stirring blade 13 extends vertically.

Also, at the inner bottom of the rotating washing tub 3, a low mountain-shaped stirring blade 1 is installed.
4 is formed. This rotary washing tub 3 is rotated by a short cycle forward and reverse rotation of an electric motor 4.

Now, by dividing the laundry into the inside and outside of the rotating washing tub 3, adding detergent and washing water, and operating the electric motor 4, the rotating washing tub 3 is rotated forward and backward in short cycles, and the laundry is Washing is performed.

Since there is no exchange of washing water between the inside and outside of the rotating washing tub 3,
This allows you to wash colored items and white items separately.

The outside of the rotating washing tub 3 has strong cleaning power. The cleaning power on the inside is weak. Workers who get a lot of dirt can clean their clothes by washing their underwear on the outside and their underwear, which is less dirty, on the inside. Also, by washing items made from weak fabrics on the inside, damage to the fabric can be suppressed. Furthermore, you can wash large items on the outside and small items such as handkerchiefs and stockings on the inside.

In FIG. 2, the outer frame 1 and the washing tub 2 are integrally formed of plastic. Since the outer frame 1 is usually formed of a steel plate, it is necessary to provide a sealing backing at the part where it meets the washing tub 2. Since the outer frame 1 and the washing tub 2 are integrally formed of glass, it is easy to manufacture. In addition, since the outer frame 1 and the washing tub 2 are integrally connected at the upper part, water does not leak into the outer frame 1 even without providing a seal backing, and the electric motor etc. installed inside the outer frame 1 can be Insulation defects of parts (not shown) can be suppressed.

The washing tub 2 vibrates due to forward and reverse rotation of the rotating washing tub 3 or high-speed rotation during spin-drying, but since the outer frame 1 is made of plastic, the vibrations and noise are absorbed. It is lighter than steel plate. Since this washing machine is a portable type washing machine, it is particularly desirable to make it lightweight.

Moreover, when the washing tub 2 is integrated, the internal volume of the washing tub 2 can be increased compared to when it is made separately.

The one shown in FIG. 3 is characterized by the fact that a large number of small water passage holes 15 are provided in the rotating washing tub 3', and the other configurations are the same as the one shown in FIG. 1.

Now, when the electric motor 4 is operated to rotate the rotating washing tub 3' forward and backward in a short period of time, the washing water in the rotating washing tub 3' flows from the small water passage hole 15 to the rotating washing tub 3' due to the action of centrifugal force. leaks out to the outside. Since the 5-turn washing tub 3' repeats forward and reverse rotation,
The washing water that flows out during switching returns from the small water passage hole 15. First, washing water enters and exits the rotating washing tub 3' through the small water passage holes 15, and the water level in the rotating washing tub 3' rises and falls as the rotating washing tub 3' rotates in the forward and backward directions. Due to this vertical fluctuation of the water level, the laundry in the rotating washing tub 3' has a pushing action of moving up and down, making it suitable for washing items made of weak fabrics such as wool and stockings. Also, items with little dirt can be thoroughly washed inside. Items with a lot of dirt can be removed by cleaning them outside.

The laundry can be dehydrated by draining the washing water and continuously rotating the rotating washing tub 3' in one direction.

The one shown in FIG. 4 differs from the one in FIG. 1 in the rotary washing tub 3''.The other configurations are the same as in FIG. 1.

In other words, there is a lance ring 1 on the top of the rotating washing tub 3''.
6, the inner lower part of the balance ring 16 is used as a locking part, and a lint collection filter 17 which also serves as a safety force and (-) is detachably attached to this locking part.This lint collection filter Reference numeral 17 is made of flexible plastic and has a large number of small holes.The outer diameter is slightly larger than the inner diameter of the rotary washing tub 3''.

The lint collecting filter 17 should be bent and the lance ring 1
6 and is inserted into the inner circumferential surface of the rotating washing tub 3" to be held there. Note that the balance ring 1
The lower part of the inner side of 6 is used as a locking part to prevent the lint collecting filter 17 from coming off due to the rotation of the rotary washing tub 3''.

Now, when the rotating washing tub 3'' is rotated forward and reverse by the electric motor 4,
The washing water in the rotating washing tub 3'' is diverted to the outside of the rotating washing tub 3'' through the small water passage holes 15 by centrifugal action. The outside washing water flows into the rotating washing tub 3'' through the small holes of the lint collecting filter 17 in proportion to the outflow. When washing is finished, the lint collecting filter 17 is immediately removed and the lint is removed.

The rotating washing tub 3'' pauses at the time of switching between forward and reverse rotation, but in order to prevent the collected lint from floating up from the lint collection filter 17, it is desirable to make the pause time as short as possible.

Further, since the lint collecting filter 17 has a large area, it does not become clogged even when a large amount of lint is collected, and has a good collection effect.

When the rotating washing tub 3'' is used as a dehydrator that rotates continuously in one direction, it can be used as a safety cover to prevent laundry from flying out.

FIG. 5 shows the inside of the clutch section 8 mainly from the perspective of operation. This one consists of two coupling parts. The driving side coupling 18 is attached to the rotating shaft 9, and the driven side coupling 19 is attached to the rotating shaft 10.

A protrusion 20 is provided on the outer surface of the driving side coupling 18, and a bone protrusion 21 is provided on the inner surface of the driven side coupling 20.

When the electric motor rotates 400 times, the drive side coupling 18 rotates, and the protrusion 20 engages with the two bone protrusions, whereby the rotation of the drive side coupling 18 is transmitted to the conventional side coupling 19.

This rotation transmission will be explained in relation to the torque of the electric motor 4 based on FIG. 6. The electric motor 4 starts rotating from T. 1
From 0 to Nvn' while rotating! After the protrusion 20 of the driving side coupling 18 engages with the bone protrusion 21 of the driven side coupling 19, it reverses and returns to Nw1. During this time, the rotating washing tub 3 is rotated in a forward and reverse cycle to wash and rinse. Do the following. Note that it is necessary to always perform the torque rw+1w2 between NwH and NWZ before T+a i x.

In dehydration operation, since the rotation is continuous in one direction, the rotation speed becomes more than N t m after the motor torque TmM, so dehydration can be performed using NI, , →N□, and X. .

In addition, the time of NwI + Nw 2 is 0.5" to 0.8"
Demeru.

The embodiments shown in FIGS. 7 and 8 relate to vibration isolation.

The one shown in FIG. 7 has a rotary washing tub 3a with a smaller diameter, and has the same structure as the one shown in FIG. 3 in other respects. That is, in the rotary washing tub 3a, the outer diameter d of the cylindrical portion into which the laundry is placed is made much smaller than the outer diameter of the bottom substrate. d (set to 1/2D).

For this reason, the occurrence of lance in the rotating washing tub 3a can be suppressed to a minimum.This is particularly suitable for centrifugal water washing operation.Although the volume of the rotating washing tub 3a is small, the amount of laundry put therein can be reduced. Since there are many small items, this is not a big problem.

The one shown in Fig. 8 is one in which balance rings 22 and 23e are provided at the upper and lower parts of the rotating washing tub 3b.
It has the same configuration as shown in the figure.

This one has 3 rotating washing tubs with balance rings 22 and 23.
This suppresses the unbalanced vibration of b. There is an advantage that there is no need to reduce the volume of the rotating washing tub 3a.

Since this washing machine does not elastically support the washing tub 2, it is particularly desirable to suppress unbalanced vibrations of the rotating washing tub.

FIG. 9, FIG. 1θ, and FIG. 11 show the division.

The washing machine shown in FIG. 9 is a washing machine having the configuration shown in FIG. 3, in which the rotating washing tub 3 is rotated forward and reverse while water is poured into the washing tub 3 from above. In this rinse,
As with washing, by separating the laundry by placing small items inside the rotating washing tub 3 and larger items outside,
This allows efficient rinsing without large and small items getting tangled.

The one shown in FIG. 10 is the same as the one shown in FIG. 3 except for the rotary washing tub 3c.

This rotary washing tub 3C has no small water passage holes in the cylindrical part into which the laundry is placed, and has a configuration that tapers upward.

Rotating washing tub 3 while pouring water into rotating washing tub 3C from above.
When it is rotated in the forward and reverse direction, the washing water travels along the inner wall surface of the rotating washing tub 3C and rises towards the water, due to the centrifugal action.
It is emitted from the top of C.

Since the washing water in the washing tub 2 overflows from the overflow filter, the water level in the washing tub 2 does not exceed a certain value even if water continues to be poured.

Rinsing is performed in this way, but the rinsing water in the rotary washing tub 3C becomes cleaner than in the washing tub 2, so the rinse water can be separated. Discoloration can be prevented by placing white cloth in the rotating washing tub 3C.

The one shown in FIG. 11 is the same as the one shown in FIG. 3 except for the rotary washing tub 3d.

This rotary washing tub 3d is provided with small water passage holes 15 from the upper end to the lower side of about 100W.

Rotating washing tub 3 while pouring water into rotating washing tub 3d from above.
When d is turned forward or backward, the rinsing water in the rotating washing tub 3d is discharged from the small water passage hole. Rinsing is otherwise carried out in the same manner as in the embodiment of FIG.

FIG. 12, FIG. 13, and FIG. 14 show a summary of the washing, rinsing, and dehydration described above.

That is, FIG. 12 shows a state in which washing is performed by rotating the rotary washing tub 3e. FIG. 13 shows a state in which rinsing is performed. This rinse consists of a pre-rinse and a water-filling rinse. In addition, preliminary dehydration rinsing is performed by repeating water supply and dehydration alternately.

Figure 14 shows dehydration. Dehydration is the same as preliminary dehydration.
Laundry is placed in a rotating washing tub 3e and continuously rotated in one direction.

In addition, as shown in FIGS. 13 and 14, 24 is a hot water filter, 25 is a drain valve, and 26 is a switching cock strap.
