Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a finishing agent feeding device for a two-tank washing machine having a dehydrating and rinsing function.

[Conventional technology]

This type of washing machine is equipped with a finishing agent dispenser to perform a finishing treatment in which a soft finishing agent, etc. is applied to the items to be washed after dehydration and rinsing, and the finishing agent is poured out little by little from this dispenser. However, soft finishing agents are highly viscous and tend to clog the outlet of the dispenser, requiring frequent cleaning to prevent this.

Therefore, a reservoir for charging the soft finishing agent is formed in the inner lid of the dehydration tank, which has a conduit for water sprinkling in the washing machine, and a portion of the water for sprinkling the dehydration tank is poured into this input part. It has been proposed that the finishing agent be diluted with water and sprinkled on the items to be washed.

For example, Utility Model Publication No. 58-138583 and Japanese Patent Application Laid-open No. 58-
The one shown in Publication No. 192585 is one example.

However, among these, the one disclosed in Japanese Utility Model Application Publication No. 58-138583 has something like a weir plate installed between the conduit of the inner cover and the finishing agent reservoir, and the water from the conduit is diverted from the weir plate. The soft finishing agent is guided directly through the slit into the finishing agent reservoir, and the soft finishing agent is diluted and flushed out. Therefore, the time to start adding the finishing agent to the item to be washed is determined by the timing of flowing water into the conduit of the inner lid, and the finishing agent continues to flow while water is flowing through the conduit of the inner lid for dehydration and rinsing. It turns out.

By the way, soft finishing agents are cationic, and if they are added to items to be washed that still contain anionic detergents, they will not exhibit their finishing effects. That is, if a soft finishing agent is mixed into the rinsing water during dehydration and rinsing, the finishing agent will not act on the items being washed and will be wasted. For this reason, in the above-mentioned Japanese Utility Model Application Publication No. 58-138583, the water supply is stopped once after the dewatering and rinsing process is completed, and then a separate process is specially provided to flow water into a conduit for watering. However, the number of steps increases and the cleaning time increases.

Another technique disclosed in Japanese Patent Application Laid-Open No. 58-192585 uses a movable piece that is manually opened and closed to control the period during which water is poured into the finishing agent reservoir. However, since this is a manual operation, it is difficult to select the final stage of dehydration and rinsing, and a special process is still provided after the completion of the rinsing process, similar to the above-mentioned Japanese Utility Model Application Publication No. 138583/1983.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a finishing agent feeding device for a washing machine capable of automatically and surely feeding a soft finishing agent while diluting it with water almost at the end of a dewatering and rinsing step, thereby simplifying finishing work.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a washing machine in which a water conduit is formed in the inner lid of a dehydration tank. A water storage box having a spout at the top and a top opening closed by a top plate has a part of the top plate formed into a downwardly protruding slot-shaped recess, a drop hole in the bottom of the recess, and a transparent hole in the side. A hole shall be formed respectively,
The tip of the bypass flow path branched from the dewatering side outflow part of the water supply electromagnetic valve, which consists of two valves divided into a water outflow part on the washing tank side and a water outflow part on the dehydration tank side, is connected to the reservoir part for charging the finishing agent. The gist is that an electrically opened/closed valve is provided in the middle of the bypass path, protruding into the interior of the water storage box and close to the through hole in the side of the concave portion.

[Effect]

According to the present invention, water is forcefully discharged from the bypass flow path of the water supply solenoid valve into the water storage box of the finishing agent injection storage part provided on the inner lid of the dehydration tank, and this causes the water to fill up the storage part. Dilutes and releases the finishing agent inside while rinsing the inner wall surface. In addition, water from the bypass flow path enters the slot-shaped recess through the through-hole due to its force, swirling along the inner surface of the groove, diluting the soft finishing agent in this area, and storing water from the drop-hole. flows into the box. Since the timing of introducing water into this reservoir can be automatically controlled by opening and closing a valve, the final stage of the dehydration and rinsing process can be appropriately selected.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of a finishing agent feeding device for a washing machine, and FIG. 2 is an explanatory view of the same operation. In the figure, 1 indicates the inner lid of the dehydration tank.

As is well known, this inner lid 1 is provided directly above the dewatering basket 2 so as to be openable and closable, and has a water conduit formed on its surface consisting of a water conduit 1a and a curved recess 1b communicating with the conduit 1a, and the center of the recess 1b. It has a discharge port 1c at the deepest part. When the inner lid 1 is closed and in a horizontal state, the discharge port 1c faces the upper opening of the water spray tube 2a, which is erected in the center of the dehydration basket 2 and has a large number of small holes on its surface.

3 in the figure is a water receiving case that is partitioned by a partition plate 3a and supplies water to the washing tank and the dehydration tank, and above it is a double series divided into a water outlet 4a on the washing tank side and a water outlet 4b on the dehydration tank side. A water supply solenoid valve 4 consisting of a valve is provided, and although not shown, the solenoid valve 4 is connected to a water faucet 5 via a hose and a hose joint.

In addition, the inner lid 1 is attached to the dehydration tank side of the water receiving case 3.
It is connected to the water guide groove 1a.

The above is the same structure as a conventional washing machine, but
In the present invention, a rectangular water storage box 6 is integrally formed on the inner lid 1, and a spout 6a is formed on the side of the water storage box 6 to face above the curved recess 1b of the inner lid 1.

Furthermore, the upper opening of this water storage box 6 is closed by an upper plate 7, and a part of the upper plate 7 is formed as a concave portion 7a projecting downward, and a drop hole 7b is provided at the bottom of the concave portion 7a, and a drop hole 7b is provided at the bottom of the concave portion 7a. A through hole 7c is provided in the hole 7c.

In this way, the water storage box 6 and the top plate 7 form a reservoir for charging the soft finishing agent.

On the other hand, the dewatering tank side water outlet 4b of the water supply electromagnetic valve 4 is branched to form a bypass flow path 8, the tip of which projects into the water storage box 6, and a through hole 7c on the side of the concave portion 7a. placed close to.

Note that it is desirable that the top plate 7 including the concave portion 7a be a transparent plate made of synthetic resin. In this way, the inside of the water storage box 6 can be observed from the outside, and the state of dirt etc. can be known at a glance.

A valve 9 was provided in the middle of the bypass channel 8, and a solenoid 10 was connected to the valve 9. In this way, the valve 9 is electrically opened and closed by the solenoid 10, and the opening operation of the valve 9 by the solenoid 10 is performed at the final stage of the dewatering and rinsing process as described later.

Next, usage and operation will be explained. In the dehydration rinsing step, the items to be washed are set in the dehydration basket 2, and the dehydration basket 2 is rotated at high speed by a motor to perform dehydration. At the same time, water from the water faucet 5 flows from the dehydration tank side water outlet 4b of the water supply solenoid valve 4 through the water receiving case 3, through the water guide groove 1a of the inner lid 1, and from there, the water flows through the water guide groove 1a of the inner lid 1.
recess 1b → discharge port 1c → watering tube 2 of dehydration basket 2
a, water is sprayed from the water spray tube 2a and sprinkled on the items to be washed, and dehydration and rinsing is performed.

At the final stage of the dewatering and rinsing process, the soft finishing agent 11 is put into the mortar-shaped recess 7a, and it falls little by little into the water storage box 6 through the drop hole 7b at the bottom. At the same time, valve 9 is operated by solenoid 10.
is automatically opened, and part of the water coming out of the water supply electromagnetic valve 4 flows through the bypass passage 8 and is vigorously discharged from its tip into the water storage box 6, diluting the soft finishing agent 11 therein.

Also, a part of the water discharged from the tip of the bypass channel 8 enters into the concave portion 7a through the through hole 7c due to the force, and swirls along the inner surface of the concave portion 7a. It flows into the water storage box 6 from the drop hole 7b while diluting the soft finishing agent 11 in the area.

As the water swirls in this way, the concave portion 7a is also cleaned cleanly, and the soft finishing agent 11 diluted in the water storage box 6 comes out from the spout 6a, flows over the inner lid 1, and flows from the discharge port 1c. The water is transferred to the water spray tube 2a and sprinkled on the items to be washed.

Note that there is no problem in charging the soft finishing agent 11 from the container into the mortar-shaped recess 7a before the start of the dehydration and rinsing process, for example, at the start of washing.
In this case, most of the soft finishing agent 11 is in the water storage box 6.
Some of it will remain in the concave portion 7a due to its viscosity.

Then, when the valve 9 is opened, water is poured in with great force, so that the water is diluted in a rinsing manner as described above. In particular, since the upper part of the water storage box 6 is closed by the top plate 7 and is in a substantially airtight state, the poured water is forcefully pushed out from the spout 6a so as to entrain the soft finishing agent 11.

[Effect of idea]

As described above, the finishing agent feeding device for a washing machine according to the present invention can be used in a washing machine in which a water conduit is formed in the inner lid of a dehydration tank for dewatering and rinsing.
This inner lid has a reservoir for adding the finishing agent, and when water is poured into this reservoir and the diluted finishing agent is sprinkled onto the items to be washed, the start of the water injection can be automatically selected by opening and closing the valve. The final stage of the rinsing process can be selected to effectively supply the soft finishing agent to the item to be washed.

In addition, unlike the system in which water is obtained from a branched conduit in the inner lid, water is obtained directly from the solenoid valve for water supply through a bypass flow path, so water can be injected with force, and water can be obtained from the reservoir. In this method, a part of the top plate of the water storage box is formed into a groove-shaped recess that projects downward, and a drop hole is formed at the bottom of the recess and a through hole is formed at the side, so that it can be used with viscous soft finishing agents. The finishing agent can be washed away without leaving any residue, and there is no need to clean the finishing agent reservoir.
