Furthermore, there is a partition wall 38 at the bottom of the four parts 37 of the rear panel 5 below.
A detergent receiving part formed separately from other parts by 39,
For this purpose, a water supply valve 41 in a water supply channel 40 is exposed through a water supply vibrator 42 and a water supply device 43 shown in detail in FIG. It faces the inside of a washing tub (not shown) arranged inside the outer box 1.

Reference numeral 45 designates a small lid for opening and closing the detergent outlet 17 from below, and is pivoted to the opening 35 portion of the rear panel 5 at the rear of the detergent outlet 17 by means of a support 46 for upper rotation for opening and closing. Further, a compression coil spring 47 provided between the hopper 6 and the inner wall 7 of the hopper 6 above the rear of the hopper 6 is normally biased to the closed state. On the other hand, reference numeral 48 is an operating rod provided at the lower rear position of the small lid 45, and as shown in FIG. So, that one character-shaped part 4
At the lower end of 8b, there are four support protrusions next to the detergent receiving part 36.
It is rotatably supported by.

Reference numeral 51 denotes a bifurcated portion formed at the upper end of the single-character portion 48b. 52 is an electromagnet located on the side opposite to the small lid 45 of the operating rod 48, placed on a support stand 53, and fixed with a screw 54, and has a plunger 52a, and the tip of the plunger 52a is connected by a pin 55 to the bifurcated portion 51 with an operating angle of 11°45.

When using the device constructed as described above, with the hopper 6 mounted on the rear panel 5, the lid 9 is opened and the powdered detergent 56 is poured into the hopper 6 (inside the inner wall 7). Then, by closing M9, the powdered detergent 56 is left stored in the hopper 6. In this state,
When the necessary switch operations are performed to perform laundry, a control device (not shown) using a microcomputer, for example, starts operating, and first, the electromagnet 52, motor 22, and water supply valve 41 are energized. However, among those energized in this way, the electromagnet 52 is energized, causing the plunger 5 to move.

Therefore, the operating rod 48 is moved simultaneously, and the tip of the L-shaped portion 48a pushes up the rear part of the small M45 as shown in FIG. It is liberated against the forces. On the other hand, the motor 22 is activated by energization and transmits its rotational force from the rotating shaft 23 to the driving gear 24, and further from the driving gear 24 to the driven gear 21, and then to the transmission shaft 20 and the detergent delivery member 18. By rotating the detergent delivery member 18,
In particular, the blade side 18a is rotated in a so-called screwing direction, and the other side is rotated in a so-called screwing back direction. Therefore, the powdered detergent 56 in the hopper 6 is advanced inside the detergent delivery section 16 toward the detergent outlet 17 on both sides of the detergent outlet 17 by the rotation of one side 18a and the other side 18b of the detergent delivery member 18. ,
The small M45 mentioned above is opened from the detergent outlet 17.
The detergent is discharged through the top and falls onto the detergent receiver 36. The water supply valve 41 allows water to flow onto the detergent receiver 36 through the water supply vibrator 42 and the water supply device 43, and the powdered detergent 56 that has fallen onto the detergent receiver 36 is washed away by the flowing water. Both are supplied into a washing tub (not shown).

Note that when the powdered detergent 56 is supplied as described above, the first stirring body 25 with one of the protrusions 33 engaged with one side 18a of the detergent delivery member 18 and the other side of the detergent delivery member 18 18b is engaged with one of the protrusions 34, and each protrusion 33. 34 are sequentially rotated into engagement with the detergent delivery member 18, thereby stirring and dislodging the powdered detergent 56 in the hopper 6.

According to this embodiment as described above, since the length of the hopper 6, which is the detergent storage section, in the direction of the water 314 is increased, the volume (powder detergent 5) can be increased without increasing the height.
It is possible to secure a large storage amount (accommodation storage amount of No. 6) and reduce the number of times of replenishment and storage. And like this,
Since a large capacity can be secured without increasing the height of the hopper 6, the washing machine can be easily installed without the upper part of the hopper 6 hitting the water faucet. Furthermore, even when a dryer is placed above an installed washing machine, the dryer can be placed low, making it easier to use.

In addition, powdered detergent 5 from a horizontally elongated hopper 6
The powder detergent 56 can be supplied from both sides of the detergent outlet 17 by the detergent delivery members 18 located on both sides of the detergent outlet 17. Therefore, the powder detergent 56 can also be supplied conveniently and quickly. Moreover, in this case, since the twisting directions of the coils of the detergent delivery member 18 are opposite on both sides 18a and 18b, it can be driven by a single motor 22, and the increase in cost can therefore be kept to a minimum. can.

In addition, FIG. 6 shows a different embodiment of the present invention, in which the detergent delivery member 18 consisting of one coil described above is replaced with -
In short, a detergent delivery member 6'0 consisting of two coils is used, in which a coil 57 on the blade side and a coil 58 on the other side with the opposite twist direction are connected by a connecting member 59. However, the powdered detergent 56 from the hopper 6
With the supply of , the same effects as described above can be obtained.

Also, although not particularly shown in the drawings, the detergent delivery member is not limited to a coil, but may also be a conventional screw, and a drive device for rotationally driving the detergent delivery member may also be used. However, the drive source is not limited to a motor, and may also be a conventional water wheel operating in a water supply channel. In addition, the detergent receiving portion may be other than the detergent receiving portion 36 formed in the rear panel 5 described above, for example, a washing tub. In other words, the powdered detergent in the detergent storage portion is directly inside the washing tub. Water may be supplied without using the water supply. As a whole, the present invention is not limited to washing machines, but can be similarly applied to all appliances that function using powdered detergent, such as dishwashers.

[Effects of the Invention] As is clear from the above description, the detergent supply device for a washing machine or the like of the present invention is provided with a horizontally long detergent reservoir for storing powdered detergent, and the detergent reservoir has a detergent reservoir located in the lower part of the detergent reservoir. It is characterized in that it has a detergent delivery member made of coils or screws with opposite twisting directions on both sides of the detergent outlet, and a drive device that rotates the detergent delivery member. As a result, the amount of powdered detergent stored can be increased without causing any trouble in installing a washing machine, etc., or making it difficult to use a dryer, etc. placed above it. In itself, the supply of powdered detergent can be done conveniently and quickly, and in addition, it has various excellent effects such as being able to suppress the increase in cost.
