FIG. 1 shows a plan view of the inside of the control box 10. Reference numeral 15 is a water supply solenoid valve whose inflow side is connected to a faucet through a hose 16, and whose discharge side is connected to a special pipe 18 through a hose 17.
It is connected to the. The special pipe 18 is branched into two, one of which 19 is connected to a water injection case 20 with a hose 21, and the other one 22 has a nozzle 23 formed at its tip. The special pipe 18 has claws 24 protruding from one side thereof and is engaged with the rear rising wall 25 of the base 11, and a mounting piece 26 provided on the other side.
is attached by screwing 28 to a boss 27 that stands up from the bottom wall of the base 11. The water injection case 20 has a side wall 29 integrally projecting from the base 11, and its upper surface is covered with a cover 30 that is fitted into the side wall 29, and its tip 31 protrudes outside the control box 10 for washing. It opens toward tank 2. That is, the tip opening 31 becomes a water inlet to the washing tub 2, and the hoses 17, 21 and the water inlet case 2
0 is the water supply channel heading towards the water inlet 31, and the water channel 22
becomes a branch road branching from this water supply channel. 32 is a screw for attaching the cover 30 to a boss 33 protruding from the base 11. A large number of rectifying pins 34 are vertically provided on the cover 30.

Numeral 35 is a water receiver that receives water spouted from the nozzle 23, and the water that has entered the water receiver 35 flows out from its outlet 36. A rotation shaft 37 extends integrally with the water receiver 35 . The tip of this shaft 37 is fitted into a cylinder 39 provided in a bearing pedestal 38 integrally projecting from the base 11, and the opposite side thereof is fitted into a recess 41 of a bearing pedestal 40, which is also integrally provided from the base 11. fitted inside. (See FIG. 4) A cam lever 42 is integrally formed with the rotation shaft 37. This shaft 37 is wound around the outer periphery of the shaft 37, and has one end 43 locked to a cam lever 42 and the other end 43.
5 is locked to the locking portion of the base 11 by a spring 44, so that the outlet 36 is always in the position shown by the dashed line in FIG.
2 is at the position indicated by the dashed line) in these figures, it is biased counterclockwise. At this time, cam lever 4
A stopper 46 provided on the base 11 contacts a protrusion 47 provided on the base 11 to prevent the rotation shaft 37 from rotating further in the same direction. Cam lever 42
is pushed at a predetermined time by an operating cam 49 attached to the shaft 48 of the program timer 12 to rotate the rotating shaft 37 against the spring 44, resulting in the solid line in FIGS. 2 and 5. The positions of the outlet 36 and the cam lever 42 are changed as shown in FIG.

A container 50 for storing a finishing agent in advance is integrally formed on the base 11. This container 50
A cover 51 is attached to the upper opening with screws 52 and 53. This cover 51 has an opening 54 for introducing water from the outlet 36 into the container 50 when the outlet 36 reaches the solid line position in FIG.
and a relatively large opening 55 for taking the finishing agent into the container 50, as well as a suction pipe 56 that sucks up the liquid in the container 50 by siphon action and the sucked up liquid into the washing tub. A discharge pipe 57 for injecting toward the 2 is integrally molded. 58
The two pipes 56 and 5 constitute a siphon pipe.
This is a plug that seals the upper end opening of 7. Further, as is clear from FIG. 4, this cover 51 is also integrally formed with a bearing cover 59 that presses the rotating shaft 37 of the water receiver fitted into the bearing recess 41 so that it does not slip upward. There is.

A finishing agent is charged into the container 50 by a feeder 60. This input device 60 is shaped like a gutter and is curved upward in an arc shape. Then, it is inserted into the control box 10 through the guide hole 61 provided in the front panel 9, and when it is inserted all the way (solid line state in FIG. 2), its tip is inserted into the container 50 through the opening 55 provided in the cover 51. invade. When charging the finishing agent, the finishing agent is pulled out as shown by the dashed line in the figure and the finishing agent is dripped onto the container 60, and the finishing agent flows into the container 50 due to the inclination of the charging device 60.

On the back side of the front panel 9, the input device 60 is provided.
A dosing device cover 62 surrounding the is integrally provided so that even if a large amount of finishing agent is accidentally put in at once, it will not scatter around and wet the electrical components. Also, on the back side of the input device 60, when the input device 60 is pulled out, the guide hole 6 is formed.
A stopper 64 is provided that comes into contact with a protrusion 63 provided on the edge of the opening 1 to regulate the amount of withdrawal.

A bypass path 65 is formed between the container 50 and the water injection case 20. That is, the bypass path 65 is formed by the water filling case side side wall 66 and rear side wall 67 of the container 50, the container side side wall 29' of the water filling case 20, the partition wall 68 protruding from the base 11, and the rear rising wall 25 of the base 11. The front end is inclined so that the front side is lower, and the front end, which serves as the outlet, has an opening 69 toward the washing tub 2, as is clear from FIG.
This outlet 69 is adjacent to the water inlet 31 of the water inlet case 20. The outlet 36 of the water receiver 35 is
The spring 44 always directs it toward this bypass path 65. (Dotted chain line state in FIG. 2) Therefore, the side wall 66 of the container 50 has an overflowing part 7.
A notch is formed so that when the liquid level in the container 50 rises, the liquid inside the container 50 overflows into the bypass passage 65 from this overflow part 70.

Next, the operation will be explained. This washing machine automatically performs a series of processes such as washing, rinsing, and dehydration using a program timer 12, and the cam lever 42 is operated by an operating cam 49 during the final rinsing process.
The outlet 36 of the water receiver 35 is pushed by the container 5.
0 (solid line state in FIG. 2), otherwise the outlet 36 is directed toward the bypass path 65.

Therefore, when washing or intermediate rinsing, water supply solenoid valve 1
Most of the water that comes out from the nozzle 5 is sent to the water filling case 20 via the hose 21, rectified by a number of pins 34, and supplied to the washing tub 2 from the water filling port 31. It is ejected towards. Since the outlet 36 of the water receiver faces the bypass passage 65, the water received by the water receiver passes through the bypass passage 65 and is discharged into the washing tub 2 from its outlet 69. At this time, since the outlet 69 and the water inlet 31 are adjacent to each other, the water released from the outlet 69 is combined with the water coming out from the water inlet 31, effectively becoming one water injection, and the user can avoid water leakage. There is no fear of making a mistake, and the appearance is also pleasing.

Next, when water is supplied for the final rinse, most of the water is supplied from the water inlet 31 of the water inlet case 20, but the water that is ejected from the nozzle 23 and enters the water receiver 35 has its outlet 36 in the container. 50, it is poured into the container 50 to dilute the finishing agent A stored in advance. At this time, a resistive plate 71 is integrally protruded from the bottom surface of the container 50, and the resistive plate 71 disturbs the water coming out from the outlet 36 so that the finishing agent and water are sufficiently mixed. When the liquid level in the container rises, a siphon action is activated, and the diluted liquid is sucked up through the suction pipe 56 and poured into the washing tub through the discharge pipe 57. The liquid in the container 50 is poured into the washing tub until the liquid level drops to the lower end of the suction pipe 56.

By the way, if too much water is injected into the container 50 from the outlet 36, the liquid level in the container 50 will rise abnormally, but as mentioned above, the water will overflow from the overflow part 70 into the bypass passage 65 and the water will be washed from the outlet 69. There is no possibility that the liquid will be discharged into the tank 2 and overflow into the control box 10 through the cover 51 of the container and wet the electrical components inside. If the liquid level still rises, it will overflow from the rear side wall 67 of the container to the bypass path 65. In this case, this wall 67 becomes the flood part.

In the above embodiment, the finishing agent water injection device that pours the finishing agent into the container 50 has been described, but the container 50
It is also possible to use these injection devices by putting detergent or bleach other than finishing agents in the container.

The features of the injection device according to the present invention configured as described above are summarized as follows.

Finishing agents are stored in a container in advance and are diluted with water and injected into the washing tub when needed, so there is no risk of damaging the clothes if they are exposed to highly concentrated finishing agents directly on the clothes. There is no fear.

The water poured into the container to dilute the finishing agent, etc. is an appropriate amount of water that is branched from the water supply channel leading to the water inlet to the washing tub, so a large amount of water enters the container and the mixture of finishing agent, etc. and water spreads around the area. It will not scatter.
In addition, this branched water receiver receives an appropriate amount of water, and when necessary, it is rotated to direct the outlet toward the container and inject finishing agent, etc. into the washing tub, so the water receiver receives large amounts of water. No force is applied, no large force is required for the rotation operation, and a simple operation member such as the operation cam provided in the program timer of this embodiment is sufficient, making the operation inexpensive and smooth.

An appropriate amount of water is always supplied to the water receiver regardless of whether finishing agents, etc. are injected, and when finishing agents, etc. are not injected, this water is guided to the washing tub via a bypass path.
A separate solenoid valve for supplying water to the water receiver is not required, the cost is low, and water is supplied to the washing tub even when no finishing agent or the like is injected, so that water is not wasted.

Even if the amount of water injected into the container is too large, the liquid in the container overflows from the overflow part provided in the container into the bypass path and is discharged from the bypass path into the washing tub.
The liquid in the container will not overflow into the control box and wet the electrical components inside. All of the finishing agent is poured into the washing tub, so nothing goes to waste.

In this way, the injection device is generally inexpensive, economical, and excellent.

In addition, the outlet 69 of the bypass path is connected to the water inlet 3 to the washing tub.
1, the liquid coming out of the outlet 69 will be combined with the water coming out of the water inlet 31, effectively becoming one water injection, which will improve the appearance, and there is also the risk that the liquid coming out of the bypass path will be mistaken for a water leak. do not have.
