The upper end 57 of the slit 1 is rotatably provided by inserting the
5, and a knob 58 is provided at the tip of the penetration. As shown in FIG. 7, this operating lever 52 is rotatable within a range that moves from the original position A through the container return area B to the end of the processing agent supply area C. For convenience, the words "low water level", "middle water level", and "high water level" are displayed in the agent supply area C portion. The operating lever 52 has a pressing portion 59 extending upward from the pivot hole 53 thereof, and an extending piece 61 extending in an arc shape from the lowermost engagement end 60. This operating lever 52 also forms one interlocking mechanism 62 with the protrusion 27 that receives the processing agent input container 25 . Reference numeral 63 denotes a tension spring that always urges the operating lever 52 to rotate in the direction of the original position A. Reference numeral 64 denotes a storage tank serving as a processing agent storage source, and as shown in FIG. Finishing agent is stored by supplying from. Reference numeral 66 is a cap provided on the refill port 65. 67 is a processing agent supply device, and cylinder 68
and a piston 69, and an operation panel 6.
It is installed in an inclined manner on the back side of the board with screws. Suction port 7 formed at the top of the cylinder 68
0 communicates with the bottom of the processing agent storage tank 64, a discharge port 71 formed at the bottom is connected to one end of the tube 72, and the other end is temporarily connected to the processing agent storage tank 6.
A position higher than the maximum liquid level of No. 4 is radiated so as to face into the processing agent input container 25 from above. The piston 69 has a liquid passage hole 7 having a check valve 73.
4, a pressure receiving member 76 is attached to the tip of a piston rod 75 that passes through the end wall of the cylinder 68, and a compression member 76 is provided between the pressure receiving member 76 and the end surface of the cylinder 67. The piston 69 is always connected to the suction hole 70 by the coil spring 77.
It is biased to move in the direction. In this state, the pressure receiving member 76 is pressed against the pressing portion 5 of the operating lever 52.
It is in a relationship that opposes 9. A water level switch 78 is attached to the operation panel 6 via a fixture 79 so as to be adjacent to the operation lever 52 on the left side. As is well known, this water level switch 78
It is a pressure-responsive type switch that receives air pressure through a tube 80 according to the water supply level in the rotating tank 4, that is, the washing tank. The water level can be set to three levels: low water level, medium water level, and high water level. 83 is the cam 8
1, and a gear 8 in the middle.
4, and a water level switching knob 85 is provided at the tip of the water level setting shaft 83 that extends through and projects from the operation panel 6. On the upper surface of the operation panel 6 where the water level switching knob 85 is located, "Low", "Medium", "High" and "Refill" are displayed as shown in FIG. In FIGS. 5, 6, 11, and 13, reference numeral 86 denotes a movable stopper member in the form of a horizontally long plate with a rack 87 formed on its upper edge, and the rack 87 meshes with the gear 84. It is disposed on the back surface of the operation panel 6 so as to be slidable in the left and right directions in this state, and is held so as to be slidably guided by guide protrusions 88 provided on the operation panel 6 in a three-point arrangement. In the upper edge of such a movable stopper member 86,
By forming a two-step difference on the right side where the rack 87 is not formed, a predetermined portion of the operating lever 52 from the pivot hole 53 to the operating end side selectively abuts. Stopper surface 89a, stopper surface 89b for medium water level, stopper surface 89c for high water level
has been established. As a result of the above, the processing agent measuring mechanism 90
is configured. Therefore, in this processing agent metering mechanism 90, when the water level switching knob 85 is rotated, the gear 84 rotates and the movable stopper member 86 having the rack 87 meshed with the gear 84 moves, so that the low water level stopper surface 89a and the middle Water level stopper surface 89b
And the high water level stopper surface 89c is the water level switching knob 8
5 to "low", "medium" and "high", the slits 1 are used to move the operating lever 52, respectively.
5, particularly the processing agent supply area C, so that the operating lever 52 returns to its original position A in FIG.
When the stopper surface 89a, 89b, 89c rotates toward the terminal end, which is the lower end, the slit 15 of the stopper surfaces 89a, 89b, 89c
It will come into contact with something facing you and prevent it from moving any further. In this way, the movement stroke of the operating lever 52 from the original position A is regulated to an amount corresponding to the amount of rotation of the water level setting shaft 83 of the water level switch 78, and thus the set water level.

Next, the operation of the above configuration will be explained. Now, as shown by the solid line in FIG. 5, the processing agent input container 25 is
Assume that the washing machine has been rotated counterclockwise, that is, to the loading position, due to the previous washing operation. Also,
The water level switching knob 85 is turned to the middle water level, that is, "middle" in FIG.
Suppose you are facing 5. In this state, in order to automatically inject a processing agent, such as a finishing agent, in the current washing operation, the operating lever 52 is brought into contact with the mid-water level stopper surface 89b of the movable stopper member 86 from the original position A as shown in FIG. All you have to do is rotate it all at once. This will be explained in detail below. When the operating lever 52 is rotated counterclockwise from the original position A to the terminal end D of the container return area B, the engaging end 60 of the operating lever 52 moves the processing agent input container 25 to its receiving protrusion 27. As shown in FIG. 5 by the two-dot chain line E, the processing agent input container 25 is rotated clockwise as shown by the two-dot chain line E in FIG. 51 is restored and held at the input standby position. From this state, the operating lever 52 moves up to the "middle water level" display position in the processing agent supply area C, as shown by the two-dot chain line F in FIG.
9b, the pressing portion 59 presses and moves the piston 69 in the direction of the discharge port 71 of the cylinder 68 via the pressure receiving member 76 of the piston rod 75, so that the piston 69 A certain amount of finishing agent corresponding to the stroke at this time, that is, the movement stroke of the operating lever 52 from the D position in FIG. It is supplied into the input container 25. in this case,
The above processing agent supply area C of the operation lever 52
When the operating lever 52 and the extending piece 61 are rotated in the interior, the extending piece 61 that is integrated with the operating lever 52 engages the receiving protrusion 2
It simply slides on the arcuate surface 28 of No. 7, thereby preventing further rotation of the processing agent input container 25 in the clockwise direction. Also, move the operating lever 52 from the original position A to the intermediate water level stopper surface 89b as described above.
As described above, the processing agent input container 25 is returned to its original position and a predetermined amount of automatically measured processing agent is supplied thereto by rotating the container 25 at once until it comes into contact with the operating lever 52. When released, it is automatically returned to its original position A by the tension spring 63, and its engaging end 60 separates from the receiving protrusion 27, so that the processing agent input container 25 is prevented from rotating counterclockwise by the operating lever 52. It will no longer be done. Now, the washing operation is started in the above state, and when it moves to a predetermined stroke, for example, the final rinse stroke, of course the water supply valve 12 is operated at this time, but the operating rod 45 is connected to the cam protrusion of the cam 11. 44 in the opposite direction of the arrow 48 to release the holding caused by the engagement between the engaging claw portion 51 and the engaging protrusion 50, so that the processing agent input container 25 is moved by gravity to the position shown in FIG. As shown by the solid line, it rotates to the loading position and discharges the finishing agent inside, which is finally discharged from the water inlet 24 into the rotating tank 4, completing the so-called automatic loading of the finishing agent. .

For the above, the water level switching knob 85 is set as shown in FIG.
When the rotation is set to "low" or "high", the movement stroke of the operating lever 52 is regulated to the "low water level" or "high water level" display position in FIG. amount of finishing agent is added.

Next, the second embodiment will be explained with reference to FIG. 14, in which the same parts as in FIG. In addition, one end of a lever 93 is fixed to the water level setting shaft 83 instead of a gear, and the other end is rotatably engaged with a pin 94 in the elongated hole 92, so that as the water level switching knob 85 is rotated, The movable stopper member 91 is made to slide left and right.

In addition, the present invention is not limited to the above embodiments. For example, the gear 84 may be used as the water level switching knob 8.
It may be formed integrally with the washing tank 5, or the finishing agent may be directly fed into the washing tank from the processing agent supply device 67. Furthermore, the operating lever 52 is returned to the original position A and each selected stopper surface 89a, 89b, 8.
The processing agent may be supplied in a fixed amount by moving the processing agent to and from the processing agent 9c a plurality of predetermined times. It goes without saying that the treatment agent here includes not only finishing agents but also detergents and the like.

As is clear from the above description, the present invention can provide the following effects. The processing agent is supplied from the processing agent storage source by the processing agent supply device in an amount corresponding to the movement stroke of the operating rod (the operating lever described in the example), and the movement stroke of the operating rod is controlled by the water level switch. Since it is configured to be regulated by a movable stopper member interlocked with the water level setting shaft, it is possible to always supply the processing agent in an amount corresponding to the water supply level. In addition, in this case, the movement stroke of the operating rod is regulated by being stopped by the movable stopper member, so that the operating rod does not move too far, and it is possible to prevent excessive and erroneous injection of processing agent. Since it is only necessary to move the movable stopper member until it receives a movement-preventing force from the movable stopper member, the operation can be easily performed without having to read the scale or the like. These effects are achieved by interlocking the movable stopper member with the water level setting shaft of the water level switch, so there is no need for an independent operation for measuring, and in this respect, the operation is extremely easy. At the same time, the configuration is also extremely simple.

In particular, in the embodiment described above, since the operating rod is arranged horizontally adjacent to the water level setting shaft and the movable stopper member is arranged so as to be slidable, the displacement of the water level setting shaft is transmitted to the movable stopper member. In addition, the configuration for determining the relative positional relationship between the displaced position of the movable stopper member and the operating rod in a predetermined stroke relationship is facilitated, and as a result of the movable stopper member having a sliding structure, The necessary strength against the external force received from the operating rod can be easily obtained with a simple configuration of only the sliding guide portion such as the guide protrusion.
