Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a detergent supply device for a washing machine, etc., which is configured to supply detergent, particularly powdered detergent, to a detergent receiving portion of a washing machine, etc. using the power of a motor. Regarding.

(Prior Art) Conventionally, detergent supply devices such as washing machines used for supplying powdered detergent of this kind have generally used a detergent supply device that is driven by a motor to collect and store powdered detergent stored in a hopper-shaped detergent storage section. There is a detergent dispenser such as a screw that dispenses the detergent and supplies it into a washing tub serving as a detergent receiver.

(Problem to be Solved by the Invention) However, the above-mentioned detergent has a problem in that it tends to harden due to moisture and humidity, which is characteristic of equipment that handles water such as washing machines, before the powdered detergent is supplied. On the other hand, since the motor was normally energized and the detergent dispensing member was normally driven, the torque was insufficient and the detergent dispensing member tended to stop in the solidified powder detergent, resulting in the powder detergent supply being interrupted. There was a problem in that sufficient washing performance could not be obtained due to the insufficient amount, and variations occurred in the amount supplied, resulting in uneven washing.

The present invention has been made to solve the above-mentioned problems, and therefore, its purpose is to be able to forcefully drive the detergent dispensing member even in the case of hardened powder detergent, thereby making it possible to supply a sufficient amount of powder detergent and to stabilize it. Our goal is to provide an excellent detergent supply device for washing machines, etc.

In FIG. 4, 34 is a timer, which controls first to seventh timer switches 36 to 42, which are opened and closed as shown in FIG. 5 through a first timer motor 35 and a cam (not shown). In addition, a second timer motor 43 and an eighth timer switch 44 which is opened and closed as shown in FIG. In FIG. 5, the hatched area represents the closed state between the switch contacts, and the other blank areas represent the open state between the switch contacts. 45 is a water level switch that responds to the water level stored in the washing tub; 46 is a lid switch that responds to opening and closing of the lid 4; 47 is a first electromagnet that is a driving source for the water supply valve 27; 48 is not shown in the figure. The second electromagnet 49, which is the driving source for the drain valve, is a motor for washing and dewatering. Also, 50
A plug is plugged and connected to a power outlet (not shown), and is connected to the first and second electromagnets 47, 48, the motor 49, and the motor 3 for driving the detergent dispenser member 28.
1, the water level switch 45. The connections are made through a lid switch 46 and a timer 34 as shown.

Now, in the case of the device configured as described above, in order to use it, first open the lid 15 of the hopper 11, put powder detergent≦1 into the hopper 11 in this state, then close the lid 15, and then is stored in the hopper 11. Then, when the necessary switches on the operation panel 5 are operated to wash the clothes, in the first "wash" process, the timer 34 is activated as shown in FIG. Close the contacts C-a of the timer switch 38 of the second timer switch 37.2i3, the contacts C-a of the fourth timer switch 39, and the contacts C-a of the fifth timer switch 40. Moreover, at this time, the water level switch 45 is in a state where the contact piece COM-NC on the normally closed side is closed based on the fact that water has not been supplied to the washing tub yet, so the first timer switch 36- Contact piece COM-NC of water level switch 45 - third timer switch 3
The first electromagnet 47 is energized through the contact pieces ca and 8, and the energized first electromagnet 47 opens the water supply valve 27. Therefore, water supply from the water supply valve 27 to the inside of the washing tub is started, and in this situation, the second timer motor 43 is simultaneously energized, and the contact piece C of the third timer switch 38 is turned on. -a to the contact piece C-a of the fourth timer switch 39 and the eighth timer switch 4
A motor 31 for driving the detergent dispensing member 28 is energized via the motor 4 . At this time, the eighth timer switch 44 is intermittently closed by the second timer motor 43 as shown in FIG. It is energized periodically and is therefore operated intermittently.

Therefore, the detergent dispensing member 28 is connected to the rotating shaft 3 of the motor 31.
2, the motor 31 is repeatedly subjected to a large torque at startup through the engagement structure between the transmission bottle 33 and the connector 30 and the transmission shaft 29, and as a result, the rotation progresses powerfully. Even if 51 is frozen, it continues to rotate without being restricted by it. Note that the rotation of the detergent dispensing member 28 at this time is performed in the so-called spiral direction of the coil, so that the detergent dispensing member 28 crushes or loosens the powdered detergent 51 while moving the detergent dispensing portion 22 to the outlet 23. Proceed towards it, and exit 2

In addition, in the case of the above-described embodiment, when the water level in the washing tub reaches the set value based on the water supply to the washing tub, the water level switch 45 is actuated accordingly and the contact piece COM-N is activated.
Since the contact between C and No is opened and the contact between COM and No. , the supply of the powdered detergent 51 from the hopper 11 is also stopped, and the first timer motor 35 is instead energized via the second timer switch 37.
from the timer switch 37 to the fifth timer switch 4
The motor 49 is alternately energized in both forward and reverse directions through the contacts C-a of the 7th timer switch 42 and between the contacts ca and C-b of the seventh timer switch 42 (alternately opened). Laundry t
Washing is carried out by rotating the agitator (also not shown) in 6 alternately in both forward and reverse directions. In addition, the operation of the washing machine is as follows:
After this, "drain", "dewater", "rinse", "drain"...
・The detailed explanation thereof is not directly related to the present invention and is therefore omitted.

6 and 7 show different embodiments of the present invention. In particular, as shown in FIG. 6, a hopper 52, which is a detergent storage section, is provided above the detergent receiving section 25 of the receiving plate 24. At the lower end of this hopper 52, in place of the aforementioned coil-shaped detergent dispensing member 28, a rotary impeller-shaped detergent dispensing member 53 is provided, housed in a casing 54, for storing and dispensing a fixed amount of powdered detergent 51. Fig. 7 shows the detergent dispensing member 5.
3, a rotary shaft 56 is connected to a shaft 55 by a connector 57, and a motor 58 is shown. Of course, this motor 58 is initially operated intermittently when the powdered detergent 51 is supplied, so that the same effect as described above can be obtained.

In each of the above-mentioned embodiments, the motor 31.58 is operated intermittently only at the beginning of the detergent supply process.
By crushing the powder detergent 51, the detergent dispensing member 28 can be rotated smoothly even during continuous operation, and the time required to finish supplying the required amount of the powder detergent 51 can be shortened accordingly. If this is not necessary, the motors 31, 58 may be operated intermittently throughout the detergent supply process.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and in particular, regarding the supply of the powdered detergent 51 together with the aforementioned water supply and the stirring member 20, etc. It may be selected and implemented as appropriate. Further, the detergent receiving portion is not limited to the detergent receiving portion 125 on the receiving plate 24, but may be placed inside the washing tub. In other words, the powdered detergent 51 may be directly supplied into the washing tub. As a whole, it is not limited to washing machines, but can be similarly applied to all devices such as dishwashers that function using the powdered detergent 51, and the operation is not limited to the timer 34 but by a microcomputer etc. It may be controlled by.

[Effects of the Invention] As is clear from the above description, according to the present invention, although the detergent dispensing member can be powerfully driven by repeating the large starting torque of the motor, the detergent does not solidify in the powdered detergent. The dispensing member can be driven reliably, and the required amount of powdered detergent can be sufficiently supplied, resulting in a sufficient washing effect.Also, the supply amount can be stabilized without fluctuations, and unevenness can be avoided. This has the excellent effect of providing washing effects that would otherwise be difficult to achieve.
