Description

[Detailed Description of the Invention] The present invention relates to a detergent supply device that supplies detergent to a washing machine.

As a conventional detergent supply device, Utility Model Publication No. 52-54933
As described in the publication, there was a system in which powdered detergent was conveyed using a lead screw, but because the chute for supplying the detergent was cylindrical, it was said that the chute would easily become clogged when the detergent aggregated. There were disadvantages: the detergent supply device was only for powder, so it could not be used for liquid detergent, and there was no window to check the amount of detergent stored, so it was impossible to check the amount of detergent inside.

The present invention was developed in view of the shortcomings of the conventional methods, and its main feature is that it is possible to supply the required amount of powder, liquid, or any detergent to the washing machine with the operation of a single dial and knob. To provide a detergent supplying device which allows the amount of detergent to be confirmed from the outside and prevents clogging with powdered detergent.

Hereinafter, the present invention will be described in detail according to illustrated embodiments.

As shown in FIGS. 4 and 5, the detergent supply device A is available for powder use and for liquid use. First, the detergent feed device A1 for powder use will be explained.

The detergent storage box 2 has a rectangular cylindrical shape with an upward opening, and the bottom plate 3 has a V-shape as a whole, and a lead screw 5 is disposed in the front and back direction along this V-shaped groove 3a. Furthermore, this lead screw 5 is rotatable.

The lead screw 5 spirally moves around the shaft 9 into the feed plate 10.
is wound around the lead screw 5, and powder detergent is sent out as the lead screw 5 rotates.

Further, a detergent outlet 6 is bored at the front end of the V-shaped groove 3a of the bottom plate 3, and a chute runs from the detergent outlet 6 through the front surface 2a of the detergent storage box 2 to above the sink 7 of the washing machine 1. 8 is provided.

The chute 8 is in the form of a gutter with a substantially U-shaped cross section, and slopes downward toward the front.

Further, the front end of the shaft 9 of the lead screw 5 protrudes from the front surface 2a of the detergent storage box 2, and a dial 11 is attached thereto.

Furthermore, a canopy plate 33 is provided above the detergent outlet 6 and is inclined downwardly toward the rear to prevent the detergent 4 from falling directly into the detergent outlet 6.

Reference numeral 12a denotes a detergent storage amount confirmation window formed vertically on the front surface 2a of the detergent storage box 2, and a measuring scale 13a is provided along this window 12a.

Reference numeral 14a denotes a lid whose rear end is pivoted to the rear edge of the upper opening end of the detergent storage box 2, so that it can be opened and closed freely.

Next, the detergent supply device A2 for liquid detergent will be explained.

In this case, the shape of the detergent storage box 2 is the same as that for powder, but the bottom plate 3 is shaped like a mortar, and a detergent outlet 6 is provided at the lowest end, and further below the detergent outlet 6. A closure storage section 15 is provided in the.

The obturator storage portion 15 has a truncated conical obturator storage hole 1 with a front opening.
6 is bored, and a truncated conical closure 17 is rotatably disposed therein.

The closure 17 has detergent flow holes 18 from one side to the other side.
A rotary shaft 19 is provided forward from the front surface.

This rotating shaft 19 projects from the front surface 2a of the detergent storage box 2 and has a knob 20 attached thereto.

Further, a spring 32 is disposed on the rotating shaft 19, and the closing member 1
7 is pressed into the closed housing hole 16.

The lower end of the closure storage section 15 has a bellows-like chute 29.
is pulled out to the front.

In addition, the detergent storage box 2 for liquid detergent includes a lid 14b, a detergent storage amount confirmation window 12b, and a measuring scale 1, as in the case of powder detergent.
3b is provided.

Reference numeral 21 denotes an installation stand on which the washing machine 1 is installed, and the detergent supply device A. , A2 are juxtaposed.

The installation plate 23 of the installation stand 21 is plate-shaped and is designed to catch water overflowing from the washing machine 1, and drain it from a drain hole 24 provided at the bottom.

In addition, the ceiling 25 of the installation stand 21 is hollow, and a fan 26 is installed therein.
The air is let out from 7.

Further, a rail (not shown) is provided around the ceiling portion 25, and a bellows-shaped shielding cloth 28 is suspended from this rail.

Next, a case in which washing is performed using this device will be explained.

First, pour water into the sink 7. Next, powder detergent 4
When using the dial 11, rotate the dial 11 in one direction.

Then, the powdered detergent is sequentially sent forward by the lead screw 5 and falls through the chutes 8 into the water in the sink 7.

The amount of detergent 4 to be supplied is determined by the amount of feed of the lead screw 5, so if the dial 11 is rotated by the required amount, the required amount of powdered detergent 4 will be supplied.

On the other hand, when using liquid detergent 4, turn the knob 20,
If the detergent flow hole 18 of the closure 17 is connected to the detergent outlet 6 and the bellows-like chute 29, the detergent will flow down through these and into the sink 7.
It flows within.

When the appropriate amount of liquid detergent 4 has flowed into the sink 7, the inflow of detergent is stopped by returning the knob 20 to its original position.

Further, in this case, the inflow amount of the detergent 4 can be known even by looking at the measuring scale 13b.

After dissolving the required amount of detergent 4 in the water in the sink 7 in this manner, the laundry 31 is placed in the sink 7 and washed.

In addition, after washing is completed, the laundry is pulled onto a fishing rod 30 provided on the installation table 21, and the shielding cloth 28 is stretched out to hang the laundry 3.
1, and when the fan 26 is turned, the air containing moisture is discharged from the air vent hole 27 in the ceiling part 25, and the air with low humidity is introduced from below to dry the laundry 31. It can also be used as a drying area.

In addition, these detergent supply devices A. , A2 may be directly attached to the washing machine 1 as shown in FIG.

As mentioned above, in this invention, detergent is supplied from a chute using a lead screw placed along the bottom plate of the detergent storage box, so the required amount of detergent can be determined by the amount of rotation of the lead screw. This has the advantage that the metered supply of detergent can be carried out very easily.

Further, since the chute is shaped like a gutter with an upward opening, even if powdered detergent becomes wet and aggregates, it will not fall down and become clogged in the chute.

Furthermore, a detergent supply device that can supply liquid detergent by opening and closing the closure is attached to the powder detergent supply device, and can be used with either powder or liquid detergent. It has the advantage of not being limited to any type of detergent, and in addition, the front of the detergent storage box has a long and thin window for checking the amount of detergent stored at the top and bottom, so you can check the remaining amount of detergent from the outside and also check when adding detergent. Another advantage is that the amount can be visually checked.
