Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a detergent for a washing machine, etc., which is installed in a device such as a washing machine and supplies detergent, particularly powdered detergent, to a detergent receptacle thereof. Regarding the supply device.

(Prior Art) Conventionally, as a detergent supply device such as a washing machine used for supplying this type of powdered detergent, there exists, for example, the one shown in Japanese Patent Publication No. 18769/1983. This product is installed in a washing machine as a whole, and the powdered detergent stored in the washing machine is discharged by a screw driven by a water wheel installed in the water supply channel and supplied to the washing tub. It is supposed to be done.

(Problems to be Solved by the Invention) In the case of the above-mentioned conventional detergent storage part, the volume is small considering the shape of the hopper, and therefore the amount of powdered detergent that can be stored at one time is small. However, there was a problem in that powder detergent had to be replenished relatively frequently.

A possible solution is to increase the size of the detergent reservoir, both in the vertical and horizontal directions. However, in the case where the detergent storage section is made larger in the vertical direction, the overall height increases, resulting in an unsightly appearance.In addition, it is difficult to install other equipment such as a dryer above. The problem arises that the condition also worsens.

On the other hand, if the detergent storage section is made larger in the horizontal direction, the appearance will not be bad, and it will not be convenient to install other equipment such as a dryer above. Only the powdered detergent located above the screw in the detergent storage part enlarged in the direction is dispensed.
A problem arises in that powdered detergent remains in other parts.

The present invention has been made in view of the above-mentioned circumstances, and the object thereof is to provide powder powder without making it look bad or making it difficult to install other equipment such as a dryer above. To provide an excellent detergent supply device for a washing machine, etc., which can secure a large amount of detergent stored at one time and can be used without leaving any powdered detergent.

[Configuration of the Invention (Means for Solving the Problems) The detergent supply device for a washing machine or the like of the present invention is provided with a detergent storage section formed in an oblong box shape for accommodating and storing powdered detergent. A detergent dispensing member is provided in a part of the detergent storage section and dispenses the powdered detergent from an upper part toward the detergent receiving section, and the detergent dispensing member is moved in the direction of the detergent dispensing member and in the opposite direction. The present invention is characterized in that it is provided with a scraping member that is movable toward the detergent dispenser member and scrapes the powdered detergent in the detergent reservoir toward the detergent dispenser member by moving toward the detergent dispenser member.

(Function) According to the second method, the amount of powdered detergent stored at one time is:
Due to the horizontally long box-like form of the detergent storage section, a large amount of detergent storage can be secured. Then, by moving the scraping member toward the detergent dispensing member toward the horizontally long box-shaped detergent storage section, the powdered detergent other than the powdered detergent that was present in the upper part of the detergent dispensing member is removed from the detergent dispensing member. can reach the upper part of the

(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.

Reference numeral 22 denotes a coil serving as a detergent dispensing member rotatably disposed over the entire length of the detergent dispensing section 17;
One of the projections 14 of the stirring member 12 is engaged with this. Further, reference numeral 23 denotes a power transmission shaft which is inserted into the base of the detergent delivery section 17 and engages the base end of the coil 22, and a connector 24 is attached to the end opposite to the coil 22. . Reference numeral 25 denotes a motor attached to the inner surface of the left end in FIG. It is engaged.

On the other hand, reference numeral 28 denotes a guide groove formed in the lid 29 from a location adjacent to the left side of the detergent storage section 6 to the right end thereof, and as shown in FIG.
A scraping member 30 having a surface extending completely inside the coil is provided so as to be movable with its upper neck portion 31 in the direction of the coil 22 and in the opposite direction, lateral direction (horizontal direction in FIG. 1). There is. In addition, 32 is a knob projecting above the scraping member 30, 33 is a self-hinge part formed at the boundary between the part extending from the knob 32 to the neck part 31 and the lower part, This self-hinge part 3

The neck portion 31 of the scraping member 30 is inserted through the slit 35 while elastically deforming the side edge portion of the slit 35. As shown in FIG. 2, reference numeral 36 is a see-through section formed on the front surface of the detergent reservoir 6, which allows the remaining amount of detergent in the detergent reservoir 6 to be determined over approximately the entire width.

Now, in the case of the device constructed as described above, in order to use it, first open the lid 29 of the detergent storage section 6, and in this state pour powdered detergent (not shown) into the internal cup of the detergent storage section 6, and then The member 30 is moved in the opposite direction to the coil 22 (the first
(right side in the figure) and close the lid 29 by moving it all the way. When the necessary switches on the operation panel 4 are operated in order to do laundry, the water supply valve (not shown) is first energized to start water supply.In this situation, the motor 25 is then energized, and the is started, and its rotational force is transmitted from the rotation shaft 26 to the transmission shaft 23 via the engagement structure between the transmission pin 27 and the connector 24, and further transmitted from the transmission shaft 23 to the coil 22. In this way, the coil 22 is rotated, particularly in a so-called spiral direction, and the coil 22 rotated in this manner moves while coming into contact with the powdered detergent around it, and delivers the detergent while loosening the powdered detergent. Detergent outlet 19 inside part 17
Then, the detergent is discharged from the detergent outlet 19 as shown by A on the right side in FIG. The powdered detergent thus dispensed falls into the detergent receiver 21 on the receiving plate 20, where it is washed away by the water supplied through the water supply valve, and is washed away with the water, not shown. Supplied into the tank. Particularly in the case of this embodiment, when the coil 22 is rotationally driven as described above, the stirring member 12 that has one of the protrusions 14 engaged with the coil 22 sequentially moves the protrusion 14 into the coil 22.
The powder detergent is rotated so as to be engaged with the detergent powder, thereby stirring the powder detergent around the detergent powder, and if there are any lumps in the detergent powder,
By loosening it, the detergent can be smoothly introduced into the detergent delivery section 17.

By repeating the above operations, the detergent reservoir 6
Inside, the powder detergent gradually decreases particularly in the upper part of the coil 22, that is, in the left side in FIG. 1, and this can be visually confirmed by the transparent part 36. If it is confirmed that the amount of powdered detergent in the upper part of the coil 22 has decreased in this way, the knob 3

As a result, the powdered detergent existing in the part of the detergent storage section 6 in the opposite direction to the coil 22 (on the right side in the figure) is scraped up in the direction of the coil 22, and the powdered detergent is deposited in the upper part of the coil 22. is replenished. Therefore, from now on, it can be used in the same manner as described above, and if it is confirmed that the amount of powdered detergent in the side part of the coil 22 has decreased, replenish the powdered detergent in the upper part of the coil 22 by performing the same operation as described above. Repeat.

In this way, in the case of this embodiment, the powder detergent in the horizontally enlarged detergent reservoir 6 can be used without leaving any powder in the horizontally elongated box-shaped detergent reservoir 6. It is also possible to obtain the desired effect, that is, it has a better appearance because it has a better sense of stability than one that is larger in the vertical direction, and it also makes it easier to install other equipment such as a dryer above. In such a situation, a large amount of powdered detergent can be stored and stored at one time without causing any inconvenience, and the user can be freed from the trouble of frequently storing and replenishing the powdered detergent.

In particular, in the case of the above embodiment, the scraping member 30 is prevented from rotating from the self-hinge portion 33 to the left in FIG. As a result, the powdered detergent is transferred to the coil 22 of the detergent reservoir 6.
This has the further effect of preventing the particles from being deposited and remaining at the end in the opposite direction. However, this is not always necessary, and therefore, the scraping member 30 may not have the double self-hinge portions 33. In addition, the transparent part 36 may be provided only if it is necessary, and even if it is provided, the detergent storage part 6 may be entirely made of a transparent material other than the above-mentioned form. It may also be provided by doing so. Furthermore, regarding the knob 32 of the scraping member 30, it is not made to protrude from the lid 29, and the lid 29 and the detergent storage portion 6 are
It may be made to protrude from the joint part with the main body part. In addition, the detergent dispensing member exemplified by the coil 22 may be, for example, a conventional screw other than the coil 22, or may be a valve or the like. In addition, the detergent receiving part is also the receiving plate 20.
It is not limited to the upper detergent receiving portion 21, but may be placed inside the washing tub. In other words, the powdered detergent dispensed by the detergent dispensing member may be directly supplied into the washing tub. 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 description below, according to the present invention, a detergent supply device for a washing machine or the like that is installed in a device such as a washing machine and supplies powdered detergent to a detergent receiving portion thereof. The detergent storage part is formed in a horizontally elongated box shape to accommodate and store the powdered detergent, and is provided in a part of the detergent storage part to direct the powdered detergent from an upper part to the detergent receiving part. and a detergent dispensing member disposed in the detergent reservoir so as to be operable to move in the direction of the detergent dispensing member and in the opposite direction, the powder detergent in the detergent reservoir being moved in the direction of the detergent dispensing member. Since it is equipped with a scraping member that scrapes the detergent in the direction of the detergent dispensing member, it is possible to remove powdered detergent without making it look bad or making it difficult to install other equipment such as a dryer above. This has the excellent effect that a large amount of detergent can be stored at one time, and that it can be used without leaving any powder detergent behind.
