A detergent supply unit 9 is located inside the recess 33 and therefore inside the rear panel 6, and the detergent supply device 8 is located at the left end in FIG. 1 inside the upper cover 3 which is also inside the panel 6. A motor 37, which is a driving source, is covered by a waterproof cover 39 which integrally has a water receiver 38, and is attached using screws 40 shown in FIG. Reference numeral 41 denotes a drive gear which also serves as a waterproof cap attached to the rotating shaft 37a of the motor 37, and the driven gear 23 is meshed with this. Further, 42 is 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 and slid, so that the small lid 25 is attached to the spring 32.
The detergent outlet 24 is rotated outward (to the side opposite to the detergent outlet 24 direction) against the urging force of the detergent outlet 24 to open the detergent outlet 24.

Regarding the detergent supply device 8 described below, 43 are four parts that cover almost the entire rear edge of the cover 3, and cover the rear panel 6. The inner portion has a drain port 44 near the tip of the water receiving portion 38 at its bottom facing into a washing tub (not shown) disposed inside the outer box 1. . or,
In the concave portion 43, a portion located below the detergent outlet 24, which is a portion other than a portion where the detergent delivery portion 9 and the motor 37, which are a part of the detergent supply device 8, are located, includes:
The detergent receiving portion 45 is separated by partition walls 46 and 47. As shown in Fig. 6, this detergent receiving part 45 has a sloped surface with a downward slope, and a supply port 48 facing the inside of the two-legged washing tub is formed at the tip thereof. A water supply device 49 is provided at the end, and the detergent receiving portion 4 is connected to this water supply device 49.
5 and other parts except for the part in the fourth part 43 which is the inner part of the rear panel 6 and where the detergent delivery part 9 and the motor 37 etc. which are part of the detergent supply device 8 are located. The provided water supply valve 50 is 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, the hopper 13 is removed as shown in FIG. By closing the hopper 15, the powdered detergent 14 is left stored in the hopper 13. In this state, when the necessary switches on the operation panel 5 are operated to wash the clothes, a control device (not shown) using a microcomputer, for example, 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 drive gear 41, and further the drive gear 4

Rotate, especially in the 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 the detergent is discharged from the detergent outlet 24 as shown by arrow A in FIGS.
fall into. On the other hand, the water supply valve 5o allows water to flow through the water supply device 49 to the detergent receiver 4542 as shown by arrow B in FIG. Both of them are supplied from a supply port 48 into a washing tub (not shown).

Incidentally, when the detergent dispensing member 21 is rotationally driven as described above, the stirring member 2o, which has one of the protrusions 19 engaged with the detergent dispensing member 21, sequentially moves the protrusion 19 to the detergent dispensing member 21.
hopper 1.
The powdered detergent 14 in the detergent 3 is stirred so that the powdered detergent 14 can be introduced into the detergent delivery section 9 more smoothly.

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 configuration, 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.), and the opening and rear part of the panel 6, except for the part where the detergent supply device 8 is located, are provided with the detergent delivery unit 9, motor 37, etc. Since the water supply valve 50 is provided as an accessory, if the detergent supply device 8 is not installed and the rear panel 6 is not attached, then instead of the panel 6, for example, as shown in FIG. This means that there is no protrusion at all that would obstruct the attachment of the rear panel 52. Therefore, the panel 6 can be replaced with the rear panel 52 afterwards without any problem, and as a result, the model equipped with the detergent supply device 8 can be replaced with the rear panel 52 without any problem.
You can easily replace it with a model that doesn't. For this reason, compared to conventional models that required dedicated molds, etc. to manufacture models equipped with the detergent supply device 8 and models without, this is no longer necessary, improving productivity. In addition, it is possible to achieve lower prices for both models.

In particular, in the case of the above embodiment, when the push button 30 is pushed inward against the (=1 force) of the spring 32, the pawl 31 comes out of the hole 36.
9 from the hole 35, the hopper 13 can be removed as shown in FIG. Since it is released from the force of outward rotation by the convex portion 42, it is rotated inward by the biasing force of the spring 32, and comes into pressure contact with the detergent outlet 24 to close the outlet 24.

Then, from this state, the hopper 13 is removed again (=I), and the small lid 25 is again slid by engaging the tongue 28 with the convex portion 42, and is removed against the biasing force of the spring 32 as described above. The detergent outlet 24 is opened by being rotated in the opposite direction.

However, the present invention is not limited to the embodiments described above and shown in the drawings, and therefore the small lid 2 as described in -1-
It is not necessary to provide the opening/closing structure of 5, and it is not necessary to provide the small lid 25 itself.

Furthermore, the rear panel 6.52 may have a width narrower than that shown in the figure to the minimum necessary, and on the other hand, the detergent is supplied directly into the washing tub without passing through the detergent receiving portion 45. It may also be supplied without using.

Further, the detergent dispensing member is not limited to the above-mentioned coil, but may also be a valve, a screw, or the like. 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. And the detergent is powder detergent 14
In addition, it is not necessary to necessarily include an agitator 20, etc., and it may be arranged inside the rear panel 6.52, avoiding a part of the detergent supply device 8. Other than the water supply valve 50, a water level switch and the like may be considered as the original equipment for the washing operation.

[Effects of the Invention] As is clear from the following description, the washing machine of the present invention has the following effects:
The washing machine is equipped with a detergent supply device, and the detergent supply device is provided so that a part of the detergent supply device is located inside a panel that is attached to the top surface of the washing machine main body, and Since the original equipment for washing operation is installed in a part of the detergent supply device other than the part where it is located, this makes it difficult for models equipped with a detergent supply device to This can be done skillfully by modifying a model that is not compatible or by changing the panel, which has the excellent effect of increasing productivity and lowering the price.
