Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Application Field) 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 the washing machine, etc.

(Prior Art) Conventionally, as a detergent supply device for a washing machine or the like used to supply this kind of powdered detergent, detergent is housed and stored in a hopper-shaped detergent storage section, as shown in Japanese Patent Publication No. 54-43827, for example. There is a screw-shaped detergent delivery member that dispenses powdered detergent in fixed quantities, one that collects and then dispenses powdered detergent, and another that dispenses powdered detergent stored in a similar detergent reservoir as shown in Japanese Patent Publication No. 42-18769. A typical example is one that is delivered and supplied by the rotation of the cylinder.

(Problem to be solved by the invention) However, among the above, the former Japanese Patent Publication No. 54-43827
In what is shown in the publication, even though the washing machine and other equipment that handle water have a tendency to harden due to moisture and humidity at 0°C, the powder detergent is λ・1 before it is supplied. The detergent is not designed to have an effective action to eliminate the problem, and as a result, the detergent often gets clogged, making it difficult to ensure a smooth and reliable cleaning.
There was a problem in that they were not paid. Moreover, detergents were sometimes supplied in large lumps, which took a long time to dissolve and could not effectively contribute to cleaning.

On the other hand, the latter method disclosed in Japanese Patent Publication No. 42-18769 allows powdered detergent, which tends to harden, to be fed while being loosened by the detergent delivery member, and is therefore smoother, more reliable, and more convenient than the above-mentioned method. It is now available for supply. However, in this case, at the end of the supply operation, the detergent delivery member sends the powdered detergent to the dispenser cup of the detergent delivery section and stops its operation, so that the dehydration process continues even during subsequent operations. Powdered detergent may spill from the outlet of the detergent delivery section due to vibrations caused by operation, etc.
There was a problem in that the powdered detergent would stick to the areas where it fell. Also, items that fall into the washing tub,
There was even a problem in that it fell off during rinsing, reducing the rinsing effect.

The present invention has been made in view of the above-mentioned circumstances, and therefore, the first object is to supply powder detergent smoothly, reliably, and conveniently, and to provide a detergent outlet after the supply operation is completed. To provide an excellent detergent supply device for a washing machine, etc., which can be used comfortably without causing the problem of powdered Zu agent spilling from the washing machine, and which can also improve cleaning performance of a detergent storage part. It is in.

[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 delivery section facing the detergent receiving section at the lower end of the detergent storage section that accommodates and stores powdered detergent. A detergent delivery member is housed in the detergent delivery unit, and the detergent delivery member is rotatably driven by a drive device, and a lid is provided at the outlet of the detergent delivery unit. The lid is opened by an electric drive source when powdered detergent is supplied, and is closed at all other times.Also, the electric drive source is left in the main body of the washing machine, etc., and the detergent reservoir is connected from the main body of the device. The feature is that it is constructed so that it can be removed.

(Function) According to the present invention of the above means, the rotating detergent delivery member
By its rotation, the powdered detergent in the detergent storage section is sent out through the detergent delivery section and from its outlet, and after the feeding operation is completed, the detergent delivery section is closed by a lid that closes the outlet of the detergent delivery section by driving the electric drive source. This prevents detergent from spilling out. Furthermore, when cleaning the detergent reservoir, the electrical drive source for driving the lid can be left in the main body of the washing machine and the detergent reservoir can be removed, so there is no chance of the electrical drive source getting wet with water. The detergent storage section can be cleaned as desired without worrying about.

(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. 2, has an outer shell made up of an outer box 2 and an upper cover 3. In addition to being pivoted to the lid 4, an operation panel 5 is provided at the front edge in front of the lid 4, and a platform 6 is provided at the rear edge. The platform part 6 is provided with an operating knob 7 for setting the water level at the right end in the figure, and an operating knob 8 for setting the amount of detergent on the left side thereof. A hopper set port 9 is formed from the left side of the operation knob 8 to the left end of the platform 6, and below the hopper set port 9 is a box shown in FIG. As shown in FIG. 1, the hopper receiving portion 1 is formed into a square-shaped cross section and open at both ends as shown in FIG.

The hopper receiving part 10 houses a hopper 11 which is a detergent storage part and has a V-shaped cross section to match the hopper receiving part 10 and also has both sides formed obliquely, through the hopper set opening 9. At the same time, the claw part 2 formed on the left side of the hopper 11 in FIG. The claw portion 14 is elastically engaged with the right side edge of the hopper set opening 9 to fix the hopper 11 in a removable manner.

On the other hand, an M] 5 is pivotally installed in the upper opening of the hopper 11 so that it can be opened and closed by means of a lug 16 at the rear end (see Figs. 3 and 4, 5), and inside the hopper 11, A stirring member 20 having a plurality of protrusions 17 protruding in the front-rear direction, a large number of protrusions 18 protruding outward from the periphery, and a plurality of holes 19 is provided by passing the shaft 21 between the front and rear of the hopper 11. It is rotatably supported. Further, at the end of the hopper 11, a detergent delivery section 22 is formed extending from the inside of the hopper 11 to a cylindrical portion projecting outwardly to the right in FIG. A member 23 is rotatably housed over its entire length, and one of the protrusions 18 of the stirring member 20 is engaged with the member 23.

Here, 24 is an outlet located at the right end in the figure of the detergent delivery section 22, and a lid support protrusion 25 is provided above the outlet 24, and a lid 26 for opening and closing the outlet 24 is attached to this. It is pivoted so that it can be moved up and down for opening and closing. 27 is a torsion coil spring wound around the lid support protrusion 25;
One end of this is hooked onto the upper surface of the detergent feeder 22, and the other end is hooked onto the outer surface of the lid 26, so that the detergent feeder 22 is attached to the lid 26.
Roll of 2 2 J Gives rotational force in the Jj direction, and with that the lid 2
6, the outlet 24 of the detergent delivery section 22 is closed. Reference numeral 28 denotes a support piece protruding from the inner surface of the table-shaped portion 6 in one direction toward the lid 26, and 29 denotes an electric drive source, such as an electromagnet, attached thereto. The whole or part of the material is magnetic, and the lid 2
6 is magnetized by an electromagnet 29 in the opening direction.

As described above, the outlet 24 of the detergent delivery section 22 provided with the lid 26 is located on the upper surface of the receiving plate 30 disposed inside the table-like section 6, especially at the detergent receiving section 31 located approximately in the center thereof. I'm making it happen. Further, as shown in FIG. 4, the upper surface of the receiving plate 30 also serves as a water supply channel, and the receiving plate 30 is designed to gradually descend toward the supply port 2 at the tip facing the washing tub (not shown) inside the outer box 2. A water supply valve 33 is provided on the uppermost rear end portion of the water supply valve 33.

On the other hand, a transmission shaft 34 to which the base end of the detergent delivery member 23 is engaged is inserted into the end of the detergent delivery section 22 opposite to the outlet 24, as shown in FIG. A connector 35 is connected to the end opposite to the detergent delivery member 23. Corresponding to the connector 35, a motor 36, which is a driving device, is attached to the inner surface of the left side of the platform 6 in FIG. A provided transmission pin 38 is removably engaged with the connector 35.

Now, in the case of the above-mentioned item (1), when using it, first open the lid 15 of the hopper 11 as shown by the two-dot chain line in Fig. After that, the lid 15 is closed and the powdered detergent 39 is stored in the hopper 11.When the necessary switches on the operation panel 5 are operated to wash the clothes, the water supply valve 33 is first energized. In this situation, the electromagnet 29 and the motor 36 are energized, and two of the electromagnets magnetize the lid 26 to open the outlet 24 of the detergent delivery section 22 as shown in FIG. On the other hand, the rotational force of the motor '36 is transmitted from the rotating shaft '37 to the transmission shaft 34 through the engagement structure between the transmission pin 38 and the connector 35, This is transmitted to the detergent delivery member 23.The detergent delivery member 23 is thus driven to rotate, particularly in the spiral direction.
The powdered detergent in the hopper 11 moves while loosening the powdered detergent and passes through the detergent delivery section 22 to the outlet 2.
4 and exit through the opened exit 24 as shown by arrow A in FIGS. 5 and 4. The three powdered detergents thus dispensed fall into the detergent receiver 31 on the receiving plate 30, and are supplied to the detergent receiver 31 through the water supply valve 33 as shown by arrow B in FIG. The washing machine is flushed with the water, and together with the water, it is supplied from the supply port 32 into the washing tub (not shown).

Particularly in the case of this embodiment, when the detergent delivery member 23 is rotationally driven as described above, the protrusion 1 is formed on the detergent delivery member 23.
The agitating member 20 that has been engaged with one of the detergent delivery members 23 rotates so that its protrusions 18 are sequentially engaged with the detergent delivery member 23,
This agitates the powdered detergent 30 in the hopper 11, loosens any lumps of three powdered detergents, and allows smooth introduction into the detergent delivery section 22.

As described above, according to this embodiment, the powdered detergent 39 accommodated and stored in the hopper 11 (detergent storage section) can be delivered by the rotation of the detergent delivery member 23. Because the powdered detergent 39 can be fed out while being loosened by contact, compared to the conventional detergent storage section in which a fixed amount is dispensed, the detergent is stored once, and then dispensed.
Ensures that 11 powder detergents run smoothly without clogging 3 powder detergents,
In addition, it can be conveniently supplied in powder form without solidification.

After the supply is finished, the motor 36 is cut off and the electromagnet 29 is cut off, so that the rotation of the detergent delivery member 23 is stopped and the delivery of the powdered detergent is stopped.
- At the same time, M26 is released from the magnetic force of the electromagnet 29 and returned to its original state by the spring force of the torsion coil spring 27 to close the outlet 24 of the detergent delivery section 22. Also, the powdered detergent 9 is not spilled from the outlet 24 of the detergent delivery section 22, and in this way, the powdered detergent 34 is prevented from getting stuck, especially in the case of this embodiment, at the detergent receiving section 31.
．． It also prevents the detergent from falling into the washing tub through the detergent receiver 30 that whitens the detergent receiver 31, especially during the process after supply, especially during the "rinsing" process. Since it is possible to prevent the liquid from falling in the washing tub, it is possible to prevent the rinsing effect from deteriorating, and the washing machine can be used comfortably without being bothered by these problems.

In addition, in the case of the above-mentioned IIXt configuration, the hopper 11 is
Press I/■ Essay 1113 to remove the elastic claw part 14 from the right edge of the hopper set opening 9 as shown in FIG. 6, and then remove the claw part 12 from the left edge of the hopper set opening 9. The entire hopper 11 can be removed from the washing machine main body 1 while leaving the electromagnet 29 in the washing machine main body 1. When the electromagnet 29 is left in the washing machine main body 1 and the hopper 11 is removed, the water in the electromagnet 29 can be removed. The hopper 11 can be washed completely without worrying about getting wet, and desired cleaning can be performed.

Particularly in the case of this embodiment, when the hopper 11 is removed as described above, the detergent delivery member 23 is also disconnected from the transmission pin 38 and eventually the motor 36 by the connector 35.
The detergent delivery member 23 can be removed from the main body 1 of the washing machine 1, and the cleaning of the detergent delivery member 23 can be carried out as desired at the same time as the cleaning of the hopper 11.

Although one embodiment of the present invention has been described above, the present invention is not limited thereto, and in particular, the electric drive source for opening the lid 26 may be other than the electromagnet 29, for example, a motor or the like. Also, if the detergent delivery member 23 is coil-shaped, the powder detergent 39 will easily come out through the cavity after the supply is finished, so the value of the lid 26 will be even higher, but if it is screw-shaped. Even if there is, 1
(After the supply is finished, the powder detergent 39 has a fairly high profile, so it may be shaped like this screw.) The supply and the presence or absence of the agitating member 20 are also selected and implemented as appropriate. Historically, the detergent receiving part is not limited to the detergent receiving part 1 on the receiver 30, but has been used in the washing tub. In other words, the powdered detergent 30 may be directly supplied into the washing tub.
Even if '3' is a rotary drive shear drive device, it is not limited to the motor '6, but may be, for example, a water 11 operating in a water supply channel. The invention as a whole is not limited to washing machines, but can be similarly applied to all machines 2= such as dishwashers that function using powdered detergent.

[Effects of the Invention] As is clear from the above description, according to the detergent supply device for a washing machine or the like of the present invention, the lower end of the detergent storage part that accommodates and stores powdered detergent is oriented toward the detergent receiving part. A detergent delivery section is provided,
A detergent delivery member is housed and disposed in the detergent delivery unit, and the detergent delivery member is rotatably driven by a drive device, and a lid is provided at the outlet of the detergent delivery unit, and the lid is opened by an electric drive source to powder powder. Detergent #1! The detergent storage section was left open at the time of town delivery and closed at all other times, and the electrical drive source was left in the main body of the washing machine, etc., and the detergent storage section was removed from the main body of the device. Apply powdered detergent, which tends to harden due to water or humidity, to equipment that handles water, such as washing machines, smoothly, reliably, and in good condition.<1j1. In addition, it can be used comfortably without causing the problem of powder detergent spilling out from the outlet of the detergent delivery section after the supply operation is completed. This has the effect that the detergent reservoir can be cleaned as desired without worrying about such problems.
