Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a washing machine equipped with detergent loading means.

(b) Prior Art This type of washing machine has been proposed, for example, in Japanese Utility Model Publication No. 56-49586, but the conventional washing machine is of a type in which a rotating drum is disposed in the washing tub to perform so-called beating washing. Shown in Figure 2. In the same figure, 1 is the machine frame of a drum-type washing machine, and multiple springs 2
A horizontally long cylindrical washing tub 4 is elastically suspended by... and a shock absorber 3. Reference numeral 5 denotes a rotary drum with horizontal shaft and multiple holes disposed in the washing tub 4, which is intermittently rotated forward and backward at low speed during washing by a motor 6 and a pulley belt. Incidentally, during dewatering, this rotary drum 5 is rotated forward at high speed by the motor 6 or another motor (not shown) to perform centrifugal dewatering.

7 is a clothes entrance 8 for the washing tub 4 and the rotating drum 5
A lid body 9 opens and closes, and 9 is a clothing entrance on the front side of the machine frame 1.

10 is a flexible first water supply pipe that supplies washing water to the washing tub 4 from the rear, and is provided with a first water supply valve 11. 12 is a flexible drain pipe communicating with the bottom of the washing tub 4, and is provided with a drain valve 13.

14 is a detergent container located above the washing tub 4 and fixed to the top surface of the machine frame 1;
6 is provided, and this input port 16 is communicated with the upper part of the washing tub 4 via a joint pipe 17 and a flexible input pipe 18. A second water supply pipe 19 is branched from the first water supply pipe 10 from the upstream side of the first water supply valve 11, and communicates with a water supply port 20 on the side of the detergent container 14, with a second water supply valve 21 provided in the middle. . 2
Reference numeral 2 denotes a rectifier plate fixed to the upper part of the inner surface of the detergent container 14, which is inclined so as to expand downward and faces the water supply port 20. The lower end of this rectifying plate 22 is positioned with a small distance from the bottom surface 15 of the container. 23
A lid body opens and closes the upper opening of the detergent container 14, and also serves as the top surface of the machine frame 1, and is opened when detergent S is added.

The detergent S is placed in the detergent container 14 in advance. The second water supply valve 21 is opened at an appropriate time in the washing program to supply water to the container 14. Supply water is supplied by rectifier plate 22
The water is rectified to form a planar water stream, which flows down to the inlet 16 so as to wash away the detergent S. The detergent S and running water are supplied into the washing tub 4 and used for washing.

Here, if the detergent S is a powder, there is no problem because it is stored in the container 14, but if it is a liquid, it will flow directly into the washing tub 4 when it is put into the container 14, and the synchronization with the washing program will be delayed. It was difficult to take it. Therefore, a separate container is provided for the liquid detergent, and a normally-closed valve is provided, making the structure complicated and expensive.

On the other hand, it has been considered to raise the lip 24 of the input port 16 as shown in FIG. 3 to store liquid detergent. However, in this case, water remains after adding the detergent, and when the next time liquid detergent is added, the overflowing detergent may be added as is, causing water scale, etc., which has a negative impact on subsequent washing. Ta.

(c) Purpose of the invention The present invention eliminates the above-mentioned drawbacks and makes it possible to supply both powder and liquid detergents.

(d) Structure of the invention The present invention is a washing machine in which a cylindrical bush having a flange that protrudes higher than the bottom is removably inserted into an input port provided at the bottom of a detergent container.

That is, when using liquid detergent, a bucket is inserted to store the detergent, and after injection, it is removed and the remaining water in the container is drained. Therefore, not only can residual water in the container be disposed of, but also liquid detergent can be used.

(E) Embodiment The overall mechanism will be explained with reference to FIG. 1, and the main parts of the present invention will be explained with reference to FIG. 3. Elements that are the same as those of the conventional example will be given the same reference numerals and explanations will be omitted. .

A cylindrical bush 25 is inserted from above into the input port 16 on the bottom surface 15 of the container, and is made of elastic rubber, and has an annular flange 26 at the top that protrudes higher than the bottom surface 15. It is locked to the rim of the input port 16 by this. Reference numeral 27 denotes a spiral formed on the outer peripheral surface of the bush 25, which elastically presses against the inner surface of the joint pipe 17 to stabilize the inserted state. Reference numeral 28 denotes a knob that is integrally provided on the upper part of the bush 25, and is used when the bush 25 is pulled out from the input port 16.

Thus, when putting the detergent into the container 14, the lid 2
3, insert the bushing 25 into the slot 16,
Add an appropriate amount of detergent. At an appropriate time in the washing program, the second water supply valve 21 is opened to supply water, and the detergent flows down the input pipe 18 over the flange 26 by the water flow. When the program progresses and ends, turn knob 28 and press button 2.
5 from the input port 16, and the remaining water is discharged through the washing tub 4.

Incidentally, the bush 25 may be inserted only when using liquid detergent.

(f) Effects of the invention As described above, according to the invention, it is possible to dispense both powder and liquid detergents while eliminating the drawbacks caused by residual water, and the simple structure of adding a bush makes it extremely practical. It is possible to provide a washing machine of the same size.
