Description

[Detailed Description of the Invention] In recent years, soft finishing agents have become popular, especially for making clothes that come in contact with the skin feel soft by softening laundry, and are often used for washing baby diapers.

This soft finishing agent needs to be injected at the right time, and it is not effective if it is injected with detergent at the beginning of washing, but it is effective if it is added after the rinse water is clean.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a washing machine softening agent dosing device that can timely and effectively add a softening agent.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In the figure, reference numeral 1 denotes the main body of the dehydrating washing machine, which is provided with a top plate 3 having an input port 2 for loading and unloading laundry at the top, and a water supply valve 6 connected to a water faucet 4 via a pressure hose 5 at the rear. A panel 7 is installed to house the.

Reference numeral 5 holds the washing liquid and rinsing liquid during washing and rinsing, and receives the liquid extracted from the laundry during spin-drying.

16 covers between the washing and dehydration tank 10 and the liquid tank 15;
It is also a tank cover detachably attached to the upper part of the liquid tank 15.

Further, a bearing cylinder 18 is provided at the lower part of the liquid tank 15 to receive the dehydrating shaft 17 connected to the washing/dehydrating tank 10.
7 is hollow and holds a blade shaft 19 connected to the rotary blade 13 inside.

A motor 20 drives a pulley 22 via a belt 21.

The power transmitted to this pulley 22 is transferred to the bearing sleeve 18.
By switching the clutch built in, the water is transmitted from the dehydration shaft 17 to the washing and dehydration tank 10 for dehydration, or from the blade shaft 19 to the rotary blade 13 for washing and rinsing.

A drain hose 23 is connected to a drain port 24 provided at the bottom of the liquid tank 15, and is connected to the external drain hose 2 through a drain cock 25.
It communicates with 6.

27 is an overflow port provided on the side wall of the liquid tank 15, and the overflow hose 2
8 to the outlet side of the drain cock 25, and also to an external drain hose 26.

Although not shown, the liquid tank 15 is elastically suspended from the four corners of the main body 1.

Reference numeral 29 denotes an inlet provided at a part of the front corner of the upper surface plate 3, into which the soft finishing agent is inserted.
0, a socket 31 is provided in the tank cover 16 attached to the upper part of the liquid tank 15, and below the outlet 32 of this socket 31, there is a socket 31 separated from the inside of the liquid tank 15 by a partition plate 33. An injection receiver 34 is provided on the side wall of the liquid tank 15.

The partition plate 33 is provided with a substantially U-shaped pipe 35 that communicates the injection receiver 34 side with the inside of the liquid tank 15, and the lower end of this substantially U-shaped pipe 35 is connected to the inside of the liquid tank 15. is low.

In the above configuration, the effect of the soft finishing agent will be explained.

First, when putting laundry and detergent into the washing and dehydrating tank 10 during washing, a liquid soft finishing agent is injected from the injection port 29 of the top plate 3.

The soft finishing agent then enters the injection receptacle 34 of the liquid tank 15 through the receptacle 31 of the tank cover 16.

Also, a water faucet 4 is connected to the inside of the liquid tank 15 via a water supply valve 6.
When the water reaches a specified water level required for washing, washing is performed by rotating the rotary blades 130 times.

In this case, since the upper end of the partition plate 33 is formed higher than the specified water level 36 for washing, the soft finishing agent in the water injection receiver 34 does not flow out to the washing liquid side.

Next, drain and dewater as shown in the program in Figure 3.

Even during this dehydration, the soft finishing agent does not flow out from the water injection receiver 34.

When this dehydration is completed, water is supplied into the liquid tank 15 for rinsing.

In this case as well, the soft finishing agent does not flow out as in the case of washing.

Next, after rinsing is completed, drainage and dehydration are performed.

When the dehydration is completed, a water rinse is then performed.

In this case, water is poured into the washing and dehydration tank 10 from the water faucet 4 while the rotary blade 13 is rotated to perform rinsing.

During this rinsing, the water level in the liquid tank 15 rises above the specified water level, and the liquid flows through the approximately U-shaped pipe 35 to the injection receiver 34.
As the water enters the reservoir 34, the water enters the reservoir 34 over the upper end of the partition plate 33, so that the softening agent and the water mix, are diluted, and automatically flow into the liquid reservoir 15.

The soft finishing agent then comes into contact with the laundry to make it soft.

Further, the soft finishing agent does not flow out into the liquid tank 15 from the beginning of water injection rinsing, but flows out after the water level rises due to water injection and enters the injection receiver 34.

When water is drained after water injection and rinsing, the water in the water injection receiver 34 is discharged by a siphon effect due to the presence of the substantially U-shaped pipe 35, so that no water remains.

Once this drainage is completed, the next step is dehydration.

In general, it is necessary to add a soft finish agent after the rinse water is clean, so conventionally, you wait for the water to become clean by rinsing before adding it, or you stop it at the end of the rinse, and then wait until the water is clean before applying the soft finish agent. Previously, a method was used to dehydrate by adding a finishing agent, rinsing again, and stirring, but in one embodiment of the present invention, the soft finishing agent is simply placed in the injection receiver 34 at the beginning, and the timing during water injection and rinsing can be adjusted. Yo (it automatically flows out and takes effect.

Therefore, there is no need to add a soft finishing agent during the process, which saves time and effort.

Moreover, during this water injection rinsing, rinsing is performed by injecting water into the liquid tank 15 through the washing/dehydration tank 10 during the final rinse, so the water is clean, so the soft finishing agent is removed during this water injection rinsing. It is very effective when used.

Additionally, only the final rinse is a water rinse, and the rest are water rinses, which saves water.

Furthermore, the rinsing can be switched between a trial rinse and a water pouring rinse, and when the soft finishing agent stored in the injection receiver 34 is used, it is switched to the water pouring rinse, so that the usability is extremely good.

Further, if the soft finishing agent is only to be flowed out, water may be poured until the soft finishing agent flows out, and the water pouring may be stopped once the soft finishing agent has flowed out.

Also, if water remains in the injection receiver 34 provided on the side wall of the liquid tank 15, when the soft finishing agent is injected the next time washing is done, the water will overflow and the soft finishing agent will not remain in the injection receiver 34. Therefore, a substantially U-shaped pipe 35 is installed on the partition plate 33 to communicate the injection receiver 34 and the liquid tank 15,
The water remaining in the injection receiver 34 is surely drained by the siphon effect during draining.

During washing or rinsing, the water level may fluctuate due to the rotation of the water flow, and the water level may rise slightly. Since the water level is set high, even if the water level rises a little, water will not overflow from the overflow port 27.

In addition, if the water level rises to such an extent that it overflows from the overflow port 27, the height of the partition plate 33 is adjusted so that the water overflows from the overflow port 27 and does not enter the injection receptacle 34 that stores the soft finishing agent. It is higher than the height.

Therefore, the soft finishing agent will not flow out from the injection receiver 34 during washing or rinsing.

Since the injection receiver 34 protrudes outward from the outer wall of the liquid tank 15, the distance between it and the main body 1 is narrow, but since it is provided at a part of the corner of the main body, the liquid tank 15 does not oscillate laterally during dewatering. Even if it does, it will not easily hit the main body 1.

Also, when the soft finishing agent spills out, there is an overflow port 2 nearby.
7, the water will overflow before entering the washing and dewatering tank 10. Therefore, in one embodiment of the present invention, the location of the overflow port is separated from the location of the injection receptacle 34 that stores the soft finishing agent, that is, the water is separated from each other. This is prevented by providing parts of the corners of different main bodies 1.

Furthermore, the soft finishing agent is poured into the injection receiver 34 by gravity from the injection port 29 of the top plate 3 through the tank cover 16, so the operation is very simple and the injection can be carried out reliably. .

In addition, although the above embodiment described a dehydrating washing machine,
In a two-tub type washing machine, even if an injection receiver is provided in the washing tub, the same effect as in the above-mentioned embodiment can be obtained.

As is clear from the above embodiments, according to the present invention, by simply putting the soft finishing agent into the injection receiver first, it automatically flows out at the right time and comes into contact with the laundry during water injection rinsing, so that the soft finishing agent can be softened midway through the process. It does not require the troublesome work of adding a detergent, and it is possible to efficiently finish the laundry with flexibility.
