Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a detergent supply device for a washing machine, etc., for supplying detergent, particularly powdered detergent, to a detergent receiving section of a washing machine, etc.

(Prior Art) Conventionally, detergent supply devices such as washing machines used to supply this type of powdered detergent include those shown in, for example, Japanese Patent Publication No. 42-18769 and Japanese Patent Publication No. 54-43827. In these devices, powdered detergent stored in a suitable detergent storage portion is discharged by a detergent dispensing member such as a screw or a valve, and is supplied to a washing tub serving as a detergent receiving portion.

(Problems to be Solved by the Invention) In the case of the above-mentioned conventional product, the powdered detergent stored in the detergent storage part has a tendency to harden due to moisture and moisture, which is characteristic of equipment that handles water such as washing machines. However, it has not been designed to have an effective effect to eliminate this problem, resulting in frequent clogging of detergent and problems in that smooth and reliable supply cannot be carried out. Moreover, detergents were sometimes supplied in large lumps, which took a long time to dissolve and could not effectively contribute to cleaning.

In addition, in the method shown in Japanese Patent Publication No. 42-18769, when a lump of powdered detergent occurs, the powder detergent can be scraped from the lump with a screw and fed into small pieces. Although this does not cause as much of a problem, the powdered detergent still tends to solidify within the detergent reservoir, and therefore there is still a problem in that the supply of the powdered detergent is not smooth and reliable.

The present invention has been made in view of the above-mentioned circumstances, and therefore, its purpose is to loosen powder detergent in a detergent reservoir and supply it sufficiently smoothly and reliably, and in addition, to leave powder detergent in the detergent reservoir. It is an object of the present invention to provide an excellent detergent supply device for a washing machine, etc., which does not have the above-mentioned problems and can also ensure a sufficiently large internal volume of the detergent storage section.

[Structure of the Invention] (Means for Solving the Problems) A detergent supply device for a washing machine or the like of the present invention includes a detergent storage section that accommodates and stores powdered detergent, and a detergent receiving section that receives the powdered detergent from the detergent storage section. The detergent dispenser is provided with a detergent dispensing part for discharging the detergent toward the detergent reservoir, and a stirring member that operates together with the detergent dispensing member and is located in the detergent reservoir and stirs the powder detergent, and further includes a detergent dispensing member on the inner surface of the detergent reservoir. , is characterized by having an inclination angle of 30 to 50 degrees with respect to the vertical plane.

(Function) According to the above means, the stirring member that operates together with the detergent dispensing member stirs and loosens the powder detergent in the detergent reservoir, and the effect of the stirring member breaking down the powder detergent is that the detergent reservoir It has a shape that allows it to expand its internal volume, so it extends all the way to its inner surface.

(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.
The top cover 3 has a lid 4 that can be opened and closed (in addition to a partition), an operation panel 5 is provided on the front edge of the lid 4. , a table-like part 6 is provided at the rear edge.The table-like part 6 is provided with an operation knob 7 for setting the water level at the right end in the figure, and an operation knob 7 for setting the detergent 2 is provided on the left side. A knob 8 is provided.A hopper set port 9 is formed from the left side of the operating knob 8 to the left end of the platform 6.
A hopper receiving part 10 is formed below the hopper receiving part 10, which has a V-shaped cross section as shown in FIG. 3 and is open at both ends as shown in FIGS. 4 and 1.

A hopper 11, which is a detergent storage part whose lower part is formed in a V-shape in cross section to match the hopper receiving part 10 and whose left and right side surfaces are also formed obliquely, is accommodated in the hopper receiving part 10 through the hopper set opening 9. are doing.

Here, regarding the inclination of the inner surface of the hopper 11, the angle with respect to the vertical surface is θ1 shown in FIG.
, θ2 shown in FIG. 3 on both the front and rear sides, both of which are set in the range of 30 to 50'. For fixing the hopper 11, a claw portion 12 formed on the left side of the hopper 11 in FIG. This is done by elastically engaging the elastic claw portion 14 with the right edge of the hopper set opening 9.

On the other hand, a lid 15 is attached to the upper opening of the hopper 11, and a lid 15 is attached to the shaft 1 at the rear end.
6 (see FIGS. 3 and 4), the hopper 11 is pivoted to be openable and closable, and the inside of the hopper 11 has a plurality of protrusions 17 that protrude in the front-rear direction, as well as protrusions that protrude outward from the periphery. The stirring member 2 has a large number of holes 18 and also has holes 19.
0 is rotatably supported with a shaft 21 passing between the front and back of the hopper 11, and furthermore, at the lower end of the hopper 11, there is a cylindrical part protruding exclusively outward from the inside of the hopper 11 to the right side in FIG. A detergent delivery portion 22 is formed, and an outlet 23 at the tip thereof faces a detergent receiving portion 25 located approximately in the center of the upper surface of a receiving plate 24 disposed inside the platform portion 6. The upper surface of the receiving plate 24 also serves as a water supply channel, and as shown in FIG.
The water supply valve 27 is disposed on the uppermost rear end of the water supply valve.

A coil 28, which is a detergent dispensing member, is rotatably housed in the detergent dispensing section 22 over its entire length as shown in FIG. is engaged with the coil 28. On the other hand, a coil 2 is provided at the end of the detergent delivery section 22 opposite to the outlet 23.
A power transmission shaft 29 is inserted in which the base end of the coil 28 is connected, and a connector 30 is attached to the end of the power transmission shaft 29 on the opposite side from the coil 28. A motor 31 is attached to the inner surface of the left side of the platform 6 in FIG. 30 is removably engaged.

Now, in the case of the device constructed as described above, when using it, first open the lid 15 of the hopper 11 as shown by the two-dot chain line in FIG.
4, then close the lid 15 and add the powdered detergent 34.
is stored in the hopper 11. Then, when the necessary switches on the operation panel 5 are operated to wash the clothes, the motor 31 is energized before washing starts, and the energized motor 31 starts, so its rotational force is transmitted from the rotating shaft 32. It is transmitted to the transmission shaft 29 through the engagement structure between the pin 33 and the connector 30, and further transmitted to the transmission shaft 29.
9 to the coil 28.

In this way, the coil 28 is rotated, particularly in a so-called spiral direction, and the coil 28 rotated in this manner moves while contacting the powdered detergent 34 in the hopper 11 to finely powder the powdered detergent 34. The inside of the detergent delivery section 22 is connected to the outlet 23.
Proceed towards it and exit through exit 23. on the other hand,
At this time, as the coil 28 is rotationally driven as described above, the stirring member 20 that has one of the protrusions 18 engaged with the coil 28 causes the protrusion 18 to sequentially engage with the coil 28. The powder detergent 34 in the hopper 11 is thereby stirred and loosened, so that the detergent can be smoothly introduced into the detergent delivery section 22. Therefore, in the case of this embodiment, the powder detergent 34 is no longer similar to the conventional one.
The powder detergent 34 can be supplied smoothly and reliably without causing any clogging.

By the way, when the stirring member 20 acts as described above,
The powdered detergent 34 in the hopper 11 that is located around the stirring member 20 is broken down, and the effect of breaking off the powder is due to the inclination angle θ1 of the inner surface of the hopper 11. θ2
When it is small, the powder detergent 34 will not be left in the inside of the hopper 11 because it will not reach all the way to the inside surface, but if it is too large, it will not reach all the way to the inside of the hopper 11. This will leave powdered detergent behind. Therefore, the inclination angle θ of the inner surface of the hopper 11
1. The smaller θ2 is, the better; however, if it is too small, the internal volume of the hopper 11 will become small, making it impossible to accommodate and store a sufficient amount of powdered detergent 34. This is θ
1, the motor 3 is the drive device for the coil 28.
1 and the connector 30, etc., on one side, and a cylindrical part for the detergent outlet 23 (without this part, the detergent would easily flow out due to its own weight) on the other side. The lower end position of the inner surface of the hopper 11 cannot be moved, and the only way to set the inclination angle θl is to move the upper end of the inner surface. Similarly, for θ2, the lower end position of the inner surface is determined by the diameter of the coil 28. Therefore, θ1. If θ2 is made smaller, the internal volume of the hopper 11 becomes smaller.

Therefore, the inclination angle θ1. of the inner surface of the hopper 11. θ2 is
The maximum value at which things around the stirring part 20 collapse due to the action of the stirring part 20 is determined in the design, and first of all, the humidity of the atmosphere must be taken into consideration. After repeating many experiments on this, I found that
It has been found that if the powder detergent 34 crumbles at a humidity of 80%, it means that the inclination angle is at an appropriate angle. Therefore, when the experiment was repeated, the results shown in FIG. 5 were obtained. This study investigated the relationship between humidity and the angle at which detergent A (marked with O in the figure) and detergent B (marked with x) have the lowest degree of hardening due to humidity, and detergent B (marked with × in the figure), which has the highest degree of hardening due to humidity. [%] The angle at which detergent A collapses is 50° and detergent B is 30". Based on this, in this embodiment, the inclination angles θ1 and θ2 of the inner surface of the hopper 11 are 30 to 50". ” As a result, the powder detergent 34 is in the hopper 11.
This makes it possible to secure a volume large enough to accommodate and store a sufficient amount of powdered detergent 34 without leaving any residue.

Note that, as described above, the powdered detergent 34 discharged from the outlet 23 of the detergent delivery section 22, especially in the case of this embodiment, is transferred to the detergent receiver on the receiving plate 24 as shown by the arrow A in the Ryuteki 4 diagram in FIG. The water supply valve 2 can be received in the detergent receiving part 25.
7 through the water supply port 26 as shown by the arrow B in FIG.

Also, at this time, the water starts flowing before the powdered detergent 34 falls into the detergent receiving part 25'' and continues to flow even after the powdered detergent 34 has been drained, so that the powdered detergent 34 is applied to the laundry. Not only is the powder detergent 34 prevented from directly adhering to the detergent to prevent its yellowing and staining, but in particular, the powder detergent 34 is flushed out from the detergent receiving part 25 without being left behind, so that it does not become stuck. Further, regarding the rotation of the motor 31 and the delivery of the powdered detergent 34 by the coil 28, the amount of time and amount of time to be delivered can be adjusted according to the type of the powdered detergent 34 by operating the operating knob 8. In addition, in this case, the adjustment of the delivery amount by the operation knob 8 refers to a supplement to a predetermined basic delivery amount, and the basic delivery amount is determined according to the water level set by the operation of the operation knob 7. .

However, as mentioned above, it is necessary to supply powder detergent 34 together with water supply, control the time width of water supply at that time, and adjust the delivery amount according to the type of powder detergent 34. It is also possible to select and implement only the following as appropriate. Furthermore, the detergent receiving part is not limited to the detergent receiving part 25 on the receiving plate 24, but may be inside the washing tub.
4 may be directly supplied into the washing tub. Moreover, the detergent dispensing member is not limited to the above-mentioned coil 28,
It may be a conventional screw or valve, etc., and the motor 3 can also be used as a drive device to rotate these detergent dispensing members.
1, and may be, for example, a water turbine that operates in a water supply channel. The stirring member 20 is not limited to one that receives rotational force from the detergent dispensing member (coil 28), but may be rotated by receiving a separate driving force. In addition, the invention as a whole is not limited to washing machines, but can be similarly applied to all appliances that function using powdered 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 practiced with appropriate changes, particularly in terms of the specific shape of the stirring member, etc., without departing from the gist of the invention. obtain.

[Effects of the Invention] As is clear from the above description, the present invention provides a detergent supply device for a washing machine, etc., which supplies powdered detergent to a detergent receiving portion of a washing machine, etc., which accommodates the powdered detergent. A detergent storage section that stores detergent, a detergent dispensing member that discharges the powdered detergent from the detergent reservoir toward a detergent receiving section, and a stirring member that operates together with the detergent dispensing member and is located in the detergent storage section and stirs the powdered detergent. Since the inner surface of the detergent storage part has an inclination angle of 30 to 50 degrees with respect to the vertical plane, the powder detergent tends to harden due to moisture and humidity, which is characteristic of washing machines and other equipment that handle water. The powder detergent can be loosened in the detergent reservoir and supplied smoothly and reliably, and in addition, no powder detergent remains in the detergent reservoir, and the internal volume of the detergent reservoir is sufficiently large. It has an excellent effect in that it can also be used.
