The detergent is dispensed in fixed amounts by a manually operated valve and supplied into the washing tub.

(Problems to be Solved by the Invention) However, in the case of the above-mentioned valve, since the valve is manually operated, there is a problem that handling is troublesome.

The present invention has been made in view of the above-mentioned circumstances, and therefore, its purpose is to provide a detergent supply device such as a washing machine that can supply detergent without bothering the user, and is also highly safe. It is on offer.

[Configuration of the Invention (Means for Solving the Problems) The detergent supply device for a washing machine or the like of the present invention includes a detergent storage container with an openable/closable lid, and a detergent storage container provided inside the detergent storage container. a detergent dispensing member, a drive device using a motor as a drive source for driving the detergent dispensing member, and a switch responsive to opening/closing of the lid of the detergent storage container, the switch closing the lid. The present invention is characterized in that the motor can be energized only in the state.

(Function) According to the above means, the detergent stored in the detergent storage container is dispensed by the detergent dispensing member driven by the drive device and supplied to the washing section of the washing machine or the like. Also, this is done only when the lid of the detergent storage container is closed to prevent hands etc. from entering the container.

(Example) An example in which the present invention is applied to a detergent supply device for a washing machine will be described below with reference to the drawings.

First of all, the washing machine main body 1, whose entire structure is shown in FIG.
It is constructed by applying 1 cover 3 to the
The upper cover 3 has a lid 4 pivoted thereon so that it can be opened and closed, and also has an operation panel 5 located on the front edge in front of the lid 4, and a platform 6 on the rear edge. The platform part 6 is provided with an operation knob 7 for setting the water level at the right end in the figure, an operation knob 8 for setting the detergent 2 on the left side, and further from the left side. A rectangular opening 9 is formed toward the left end. Below the opening 9 is a receiving part 10 which has a V-shaped cross section as shown in FIG. 3 and has both ends open as shown in FIG.
It is formed in series with the peripheral edge of the opening mouth 9. Uke is part 10
A detergent storage container 11 whose lower part is formed into a V-shaped cross section to match the receiving part 10 and whose both sides are also formed obliquely is housed through the opening 9.1. At the same time, the claw portion 12 formed on the left side of the detergent storage container 11 in FIG.
An operation protrusion 13 formed on the right side and engaged with the left side edge of the
By elastically engaging the elastic claw portion 14 with the right side edge of the opening 9, the detergent storage container 11 is prevented from falling off with a removable structure that will become clear later.

On the other hand, inside the detergent storage container 11, there is a stirring member 18 having a plurality of protrusions 15 protruding in the front-rear direction, a large number of protrusions 16 protruding outward from the periphery, and a plurality of holes 17. is rotatably supported between the front and rear of the detergent storage container 11, and furthermore, at the lower end of the detergent storage container 11, there is a cylinder projecting from inside the detergent storage container 11 exclusively outward to the right in FIG. A detergent delivery portion 20 is formed across the shaped portion, and an outlet 21 at the tip thereof faces a detergent receiving portion 23 located approximately in the center of the upper surface of a receiving plate 22 disposed inside the platform portion 6. . The receiving plate 22 has two sides that also serve as water supply channels, and as shown in FIG. 4, it gradually slopes downward toward the supply port 24 at the tip facing the washing tub (not shown), which is the washing section inside the outer box 2. A water supply valve 25 is disposed on the rear end, which is the outermost part. A coil 26, which is a detergent dispensing member, is rotatably housed in the detergent dispensing section 20 over its entire length as shown in FIG. One of the projections 16 is engaged with the coil 26. A transmission shaft 27 is inserted into the end of the detergent delivery section 20 opposite to the outlet 21, and the transmission shaft 27 engages the base end of the coil 26.
A connector 28 is attached to the end of the transmission shaft 27 opposite to the coil 26 to prevent the coil 26 from coming off, thereby integrating the coil 26 with the detergent storage container 11 and making them into a unit. I'm trying. Further, a driving device 32 is provided on the inner surface of the left side of the platform 6 in FIG. , the transmission pin 31 is removably engaged with the connector 28, so that the entire unit of the detergent storage container 11 and the coil 26 can be separated from the drive device 32.

Here, on the open upper surface of the detergent storage container 11,
The lid 33 is pivoted to be openable and closable by a shaft 34 at the rear end shown in FIG. 5 as well as FIGS. A fan-shaped operation part 35 is formed in series with the side wall 33a of the lid 33, and the upper part is enlarged when the lid 33 is closed, and the radial distance from the shaft 34 to the rear is shown in FIG. As shown in FIG. 6, 36 is a cylindrical portion formed on the back surface of the detergent storage container 11 toward the operating portion 35 so as to be oriented downward, and a rod 37 can be moved downwardly into this cylindrical portion. (See Figure 7)
A spring 38 is also inserted into the cylindrical portion 36 at the same time, thereby applying an upward moving force to the rod 37, and causing the upper end of the rod 37 to come into contact with the operating portion 35 from below. There is. 39 is located below the cylindrical portion 36 i! l' is an operating member attached to the lower end of the rod 37 with a screw 40, and correspondingly, a switch 41 is installed in the platform part 6 of the upper cover 3 and is attached to a switch support part 42. and the actuator 43 is connected to the operating member 39.
When the lid 33 is closed, the switch 4 is pressed.
1 is in an open state. Therefore, the switch 41
As shown in the figure, a timer 45 and the motor 29 of the driving device 32 are connected in series to a power source 44 .

Now, in the case of the device constructed as described above, when using it, first open the lid 33 of the detergent storage container 11 as shown by the two-dot chain line in FIG. Accept 46 and then! Close 33. Then, in response to this, the switch 41 is opened as described above, and on the other hand, after closing the lid 33, when the necessary switches on the panel 5 are operated to wash the clothes, the washing is done. Prior to the start of the rotation, the motor 29 of the drive device 32 is energized via the above-mentioned closed switch 41 and timer 45, and since the energized motor 29 is started, its rotational force is applied to the rotating shaft 30. From transmission pin 3
1 and the connector 28 to the transmission shaft 27, and from the transmission shaft 27 to the coil 26. In this way, the coil 26 is rotated, particularly in a so-called spiral direction, and the coil 26 is rotated in this manner.
The detergent 6 moves in contact with the powdered detergent 46 in the detergent storage container 11, breaks the powdered detergent 46 into small pieces, advances the interior of the detergent delivery section 20 toward the outlet 21, and then discharges the powdered detergent 46 from the outlet 21. The powdered detergent 46 thus dispensed is received in a detergent receiver 23 on the slope 22 as shown by arrow A in FIG. 4 as well as in FIG. 25 as shown by arrow B in FIG. 4, and is supplied together with the water from the supply port 24 into the washing tub (not shown).

In particular, in the case of the above embodiment, when the coil 26 is rotationally driven as described above, the stirring member 18 that has engaged one of the protrusions 15 with the coil 26 sequentially engages the protrusion 15 with the coil 26. The powder detergent 46 in the detergent storage container 11 is thereby stirred, loosened, and introduced into the detergent delivery section 20 smoothly.

As described above, according to the present embodiment, the detergent, particularly the powdered detergent, stored in the detergent storage container 11 is discharged by the coil 26 driven by the drive device 32 having the motor 29 as the drive source. It can be supplied to the washing tub, and unlike conventional manually operated valves, it does not require the user's hands and is thus easy to handle.
1 can be done.

Furthermore, in the case of this embodiment, when the lid 33 of the detergent storage container 311 is opened, the rod 37 is pressed from above by the operating portion 35 of the lid 33 and compresses the spring 38, as shown in FIGS. 9 and 10. As a result, the operating member 39 is lowered and the pressure on the actuator 45 of the switch 41 is released, so the switch 41 becomes open.
The energizing circuit to the motor 29 is cut off. Therefore, deafness,
That is, when the lid 33 is opened, the detergent storage container 11
If you insert your hand etc. inside the motor 2 and it starts to warp, the
9 is not energized, and the coil 26 and stirring member 1
Since the parts 8 are no longer rotated, injuries caused by touching them can also be avoided, making it much safer.

In particular, in the case of the above embodiment, once the operating protrusion 13 of the elastic claw part 14 is operated to remove the elastic claw part 14 from the edge of the opening 9, the rest is as shown in FIG. By pulling out the elastic claw portion 14 from the opening 9, and further removing the claw portion 12 from the edge of the opening 9, the connector 28 is separated from the transmission pin 31, and the detergent storage container 11 including the coil 26 is removed. can be completely removed from the washing machine, thereby removing the coil 26 and the detergent storage container 11.
(An additional effect is achieved in that the removal can be carried out easily and as desired by handling them individually and washing them with water, etc.).

And at this time, the aforementioned rod 37 and the operating section Jr.
A 39 etc. are also removed at the same time, so that the suppression of the actuator 45 can be released, so the switch 41 becomes open and the energizing circuit to the motor 29 is cut off. Even if the storage container 11 is removed and the transmission bottle 31 etc. can be touched, the motor 29 is no longer energized, and therefore the transmission pin 31 is no longer rotated, so that the user cannot touch it. It is possible to eliminate the occurrence of injuries due to this, and it is possible to make it even safer.

However, as described above, the ability to remove the detergent storage container 11 together with the coil 26 and the like, and the fact that the switch 41 responds to this, are not necessarily required in the present invention. Therefore, the detergent storage container 11 may be irremovably installed in the washing machine along with the coil 26, or the switch 41 may not respond to the removal of the detergent storage container 11. In addition, the detergent discharged from the detergent storage container 11 may be directly supplied into the washing tub, and the detergent dispensing member is not limited to the coil 26 but may also be a screw or the like. The invention as a whole is not limited to washing machines, but can be similarly applied to all devices that function using detergent, such as dishwashers.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate changes within the scope of the invention.

[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 equipped with a detergent storage container having an openable/closable lid, and has a detergent storage container installed inside the detergent storage container. a detergent dispensing member, a drive device using a motor as a drive source for driving the detergent dispensing member, and a switch responsive to opening/closing of the lid of the detergent storage container, the switch closing the lid. Since the motor can be energized only when the detergent is in a state of There is no need for hands or the like to touch the member while it is in a drivable state, resulting in excellent safety.
