Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent dissolving device for a washing machine.

[0002]

2. Description of the Related Art As a detergent dissolving device for a washing machine, a rotary impeller that is rotated by a water injection pressure is provided in a detergent container, and the synthetic detergent or powdered soap etc. placed in the detergent container is melted and put into a washing tub. What is done is disclosed in Japanese Utility Model Publication No. 61-38553.

[0003]

However, the water supply pressure may be low and the water supply amount may be small depending on the time of day and region, and in this case, there is a problem that the detergent is not sufficiently dissolved.

The present invention solves these problems.

[0005]

The solution according to the present invention is a detergent dissolving apparatus for a washing machine, which has a water supply path connecting a water supply hose connected to a water supply source and a washing tub, in the water supply path. A dissolving case provided in the dissolving case, a detergent container detachably mounted in the dissolving case, and a stirring member rotatably mounted in the container, and a rotating shaft of the stirring member. And the motor shaft are connected by a joint.

[0006]

When the water supply to the detergent container is started, the detergent is stirred and dissolved by the stirring member and flows out into the washing tub. Further, thereafter, the inside of the detergent container is cleaned by driving the stirring member during the water supply time and stirring the water with the supplied water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in the drawings. The present invention is not limited to this.

FIG. 4 shows a fully automatic washing machine equipped with the detergent dissolving device 1, 2 is a machine frame, 3 is a washing / dehydrating tank installed in a water receiving tank 3A, and 4 is an upper end of the machine frame 2. The upper surface plate is made of synthetic resin. This top plate 4 is provided with a clothes inlet 5
A frame portion 4a that forms a housing, an operation portion 4b that stores electrical components, and a water supply device 10 that will be described later in part of the operation portion 4b.
And a detergent dissolving device 1 in which is installed. Various operation buttons (not shown), a display 7 and the like are arranged on the front panel 6 of the operation section 4b. Reference numeral 8 is a water supply hose directly connected to the tap, and the water supply device has a water supply port 9 for a washing tub via a double water supply solenoid valve and a plurality of water injection ports 11 provided in the detergent dissolving device 1. Water is supplied to 10.

1 to 3 are detailed views for explaining the detergent dissolving device 1. Reference numeral 12 is a synthetic resin box-shaped melting case having an open front surface, which is integrally formed with the operating portion 4b. The water supply device 10 is provided above the melting case 12. A step portion 13 is integrally formed on the left and right side walls of the melting case 12, the bottom surface portion is inclined downward from the rear to the front, and an outflow port 14 is provided at the front end portion. 15 is a melting case 1
2 A detergent container that can be put in and taken out through an opening on the front side. The bottom surface of the detergent container 15 is an arc-shaped mesh member of 40 to 50 mesh.
6 is fixed by a frame member 17. Reference numeral 18 denotes a protrusion integrally formed with the detergent container 15, which is held in and out with the handle 19 using the stepped portion 13 as a guide.

Reference numeral 20 denotes a stirring member, which is composed of a rotary shaft 21, blades 22 made of an elastic material, bearings 23 and 24, and a connecting pin 25 penetrating the tip of the rotary shaft 21.

Reference numeral 26 is a mower attached to the melting case 12.
The connection receiver 28 is fixed to the tip of the motor shaft 27. The connection receiver 28 has a shape of a shallow circular container, and a plurality of recesses 29 for engaging the connection pins 25 are provided at the edges of the connection receiver 28. To do.

The joint 31 is composed of the connection pin 25 and the connection receiver 28. The operation will be described based on such a configuration.

First, the detergent container 15 is pulled out from the dissolving case 12 in advance, and an appropriate amount of detergent is put into the detergent container 15. The detergent container 15 is inserted and attached while sliding with the protrusion 18 using the step portion 13 of the dissolving case 12 as a guide (the detergent container 15 shown by the broken line in FIG. 1 is taken in and out in the direction of the arrow). The connection pins 25 formed so as to project from the detergent container 15 are connected by locking all the inclined surfaces 30 of the connection receiver 28 in the recesses 29.

Next, when the operation button is operated to start washing, the solenoid valve on the washing tub side of the dual type solenoid valve for water supply is opened from the water supply hose 8 connected to the tap water tap, and the water supply port 9 is opened. Water is supplied to the washing / dehydrating tub 3 from the above, and the solenoid valve on the dissolving device 1 side is opened after a predetermined time delay and is also supplied to the water supply device 10 of the dissolving device 1. Motor 2 to dissolve the detergent
6 rotates at low speed (100 to 300 rpm), and the joint 31 drives the stirring member 20 to rotate. Then, the water is supplied from the water injection port 11 to the detergent container 15 in a shower shape, and is stirred, and the detergent is dissolved and flows out from the outlet port 14 into the washing tub. At this time, the blades 22 are pressed against the net member 16 provided at the bottom of the detergent container 15 and rotate while elastically deforming, and the detergent in the detergent container 15 is kneaded so as not to harden during that time, and the detergent does not remain. The inside of the detergent container 15 is cleaned by being stirred with water.

As described above, even when the water supply pressure is low or the water supply amount is small depending on the region and the time when the washing machine is used, the inside of the detergent container 15 is agitated by the blades 22 to allow the detergent to remain. Dissolve all the appropriate amount of detergent without adding.
Further, since the dissolved detergent is put in after the water supply is started and the laundry is wet, it is possible to prevent the detergent from intensively adhering to or remaining on the laundry, which may cause discoloration of the laundry.

[0016]

EFFECTS OF THE INVENTION According to the present invention, even if the amount of water supplied decreases due to the time of day etc., the detergent is forcibly dissolved by the stirring member in the detergent container. Can be made The detergent container can be removed from the washing machine and the detergent can be put therein without impairing the operability.
