On the other hand, 24 is a detergent outlet at the tip of the detergent delivery section 9, and the upper end of a small lid 25 is pivoted to the outer wall 12 by a shaft 26. As shown in FIG. 3, the small lid 25 has a protrusion 27 formed near its upper end.
A diagonal tongue piece 28 is formed at the rear part near the lower end. In addition, on the outer wall 12 of the hopper 13, a claw 29 is formed on one side (the left side in FIG. 1) of the lowermost sides, and on the other side (the right side in the figure).
is provided with a claw 31 that is integrated with a push button 30 that is removably installed here, and the push button 30 and the small lid 2 are connected to each other.
A spring 32 is interposed between the push button 30 and the protrusion 27 of the push button 30, and the spring 32 urges the push button 30 outward and the small lid 25 inward (toward the detergent outlet 24).

On the other hand, numeral 33 is a recess formed in the rear panel 6 by surrounding the upper edge with a rib 34 as shown in FIG. 35, and a hole 36 is formed on the other side (right side in the figure), of which hole 3
The hopper 13 is attached to the rear panel 6 by engaging the claw 29 in the hole 36 and engaging the claw 31 in the hole 36. When the hopper 13 is installed, the detergent delivery part 9 is located inside the recess 33 and therefore inside the rear panel 6, and the hopper 13 is mainly located above the rear panel 6. There is. Further, a motor 37, which is a driving source for the detergent supply device 8, is installed at the left end of the upper cover 3 in FIG. It is covered and attached using screws 40 shown in FIG. 41 is the rotating shaft 3 of the motor 37
A drive gear that also serves as a waterproof cap is attached to the drive gear 7a, and the driven gear 23 is meshed with this drive gear.
Reference numeral 42 designates a convex portion protruding from the bottom of the concave portion 33 of the rear panel 6, and the diagonal tongue piece 28 is engaged with this convex portion to slide the small lid 25 outward against the biasing force of the spring 32 ( The detergent outlet 24 is opened.

For the detergent supply device 8 described above, reference numeral 43 denotes a recess extending over almost the entire rear edge of the upper cover 3, which the rear panel 6 covers. A drain port 44 facing the inside of a washing tub (not shown) disposed inside the outer box 1 is formed near the tip of the water receiving portion 38 at the bottom thereof. In addition, in the recessed portion 43, a portion located below the detergent outlet 24, which is a portion other than the portion where the detergent delivery portion 9, which is a part of the detergent supply device 8, and the motor 37, etc. are located, includes: The detergent receiving portion 45 is formed separated by partition walls 46 and 47. As shown in FIG. 6, this detergent receiving part 45 has a front-downward slope, and has a supply port 48 facing the inside of the washing tub at its tip, and a rear end. A water supply device 49 is disposed in the portion adjacent to the detergent receiving portion 45, that is, in the recessed portion 43 which is the inner portion of the rear panel 6, and is a part of the detergent supply device 8. A certain detergent delivery section 9
and the water supply valves 50 arranged in other parts except the part where the motor 37 etc. are located are communicated. Reference numeral 51 denotes an opening formed at the bottom of the recess 33 of the rear panel 6, located above the detergent receiving portion 45, for passing the detergent through and also for cleaning.

Now, in the case of the device constructed as described above, when using it, with the hopper 13 attached as shown in FIG. 1, open the lid 15, put the powdered detergent 14 into the hopper 13, By closing the lid 15, the powdered detergent 14 is left stored in the hopper 13. In this state, when you operate the necessary switches on the operation panel 5 to wash the clothes, a control device (not shown), for example, a microcomputer built into the lower part of the operation panel 5, starts operating. The motor 37 and the water supply valve 50 are energized and operate together, and the motor 37 transmits its rotational force from the rotating shaft 37a to the driving gear 41, and from the driving gear 41 to the driven gear 23, and transmits the rotational force to the transmission shaft 22 and the driven gear 23. By transmitting the signal to the detergent dispensing member 21, the detergent dispensing member 21 is rotated, particularly in a so-called spiral direction. Therefore, the powdered detergent 14 in the hopper 13 is transferred to the detergent dispensing member 21.
Due to the rotation of the detergent, the detergent is advanced in the detergent delivery section 9 toward the detergent outlet 24, and is taken out from the detergent outlet 24 as shown by arrow A in FIGS. 1 and 6,
The detergent falls onto the detergent receiving portion 45. On the other hand, the water supply valve 50 is
Water flows through the water supply device 49 onto the detergent receiver 45 as shown by arrow B in FIG.
are swept away, and both are supplied from the supply port 48 into the washing tub (not shown).

When the detergent dispenser 21 is rotated as described above, the stirring member 20, which has one of the protrusions 19 engaged with the detergent dispenser 21, sequentially engages the protrusions 19 with the detergent dispenser 21. The powder detergent 14 in the hopper 13 is thereby
The powdered detergent 14 can be more smoothly introduced into the detergent delivery section 9 by stirring the powdered detergent 14.

As described above, according to this embodiment, the powdered detergent 14 can be supplied without leaving it in the hands of the user, and furthermore, in this structure, the detergent supplying device 8 is mounted on the upper surface of the washing machine main body 1. A part (detergent delivery unit 9, motor 37, etc.) is located inside the rear panel 6, which is a mounted panel, and a part of the detergent supply device 8 inside the panel 6. Since the water supply valve 50 is disposed in a portion other than the portion where the There will be no protrusions that would interfere with the installation of the flat rear panel 52 as shown in Figure 7. Therefore, it is possible to subsequently replace the panel 6 with the rear panel 52 without any problem, thereby easily converting a model equipped with the detergent supply device 8 into a model without it. For this reason, compared to the conventional model which required dedicated molds, etc. for manufacturing a model equipped with the detergent supply device 8 and a model without it, this is no longer necessary, improving productivity. This makes it possible to reduce the prices of both models.
In addition, in the case of the detergent supply device 8, only a part of the detergent supply device 8 is located inside the rear panel 6, and the rest protrudes above the rear panel 6. Therefore, the interior of the rear panel 6 is narrowed by the configuration of the detergent supply device 8. Since this can be avoided as much as possible and a large space can be left, the power switch 7 and water supply valve 5, which are the original equipment of the rear panel 6, can be removed.
0 It is easier to arrange other parts.

In particular, in the case of the above embodiment, when the push button 30 is pushed inward against the urging force of the spring 32, the claw 31 is removed from the hole 36 accordingly. Therefore, by removing the claw 29 from the hole 35, the hopper 13 can be removed as shown in FIG. 42 and is released from the outward forced rotational force by the convex portion 42, the spring 3
The detergent outlet 2 is rotated inward with the biasing force of the detergent outlet 2.
4 to close the outlet 24. And again,
When the hopper 13 is reattached from this state, the small lid 25 also engages the tongue piece 28 with the convex portion 42 again and slides, and is rotated outward against the biasing force of the spring 32 as described above. The outlet 24 is opened.

However, the present invention is not limited to the embodiments described above and shown in the drawings, and therefore, it is not necessary to necessarily include the opening/closing structure of the small lid 25 as described above, and the small lid 25 itself may not be provided. There's no need to.

Further, the rear panels 6, 52 may be narrower than those shown in the drawings to the minimum necessary width, while the detergent may flow directly into the washing tub without passing through the detergent receiving portion 45. The water may be supplied without using the water supply. Further, the detergent dispensing member is not limited to the above-mentioned coil, but may also be a valve, screw, etc., for example. In addition, the drive source for rotationally driving the detergent dispensing member is not limited to the motor 37, and may be, for example, a water wheel operating in a water supply channel. The detergent is not limited to the powder detergent 14, but may be a liquid detergent, etc. In addition, it is not necessary to necessarily include the agitator 20, etc., and the detergent supply device 8 is provided inside the rear panels 6, 52. In addition to the water supply valve 50, for example, a water level switch and the like may be arranged so as to avoid a portion of the water supply valve 50.

[Effects of the Invention] As is clear from the above description, the washing machine of the present invention is equipped with a detergent supply device, and the detergent supply device is attached to the upper surface of the washing machine main body. A part of the panel is located inside the panel and the rest projects upward from the panel, and at least the water supply valve is installed in the other part of the panel except for the part where the detergent supply device is located inside the panel. Since it is installed in a section, it is possible to easily modify models that are equipped with a detergent supply device with models that are not equipped with one by simply changing the panel, improving productivity and reducing costs. In addition to achieving cost reduction, if the panel part is equipped with a detergent supply device, the inner part of the panel is less narrowed by the configuration of the detergent supply device, and the original equipment of the panel can be reduced. This has the excellent effect of making the arrangement easier.
