Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing agent dispensing device for a washing machine, etc., which is capable of automatically dispensing a predetermined amount of processing agents such as detergents and finishing agents into a washing tank in a desired process.

In conventional washing machines, in order to automatically add a finishing agent, such as a finishing agent, into the washing tank at a desired process, a processing agent input container that stores a single load of finishing agent is placed below the operating box of the washing machine. However, some washers are rotatable between an input standby position where the finishing agent is stored and received and an input position where the finishing agent is discharged into the washing tank. However, according to this type of device, a part of the opening of the processing agent input container is made to protrude into the laundry loading/unloading opening, and a single use amount of finishing agent is supplied from the protruding opening to the processing agent input container. When the desired stroke is reached, the treatment agent input container is rotated to the input position and the finishing agent is discharged into the washing tank. When loading the laundry next time, it is necessary to manually return the treatment agent container that has been rotated to the loading position to the loading standby position where it can be stored again. However, there are disadvantages in that the operation becomes extremely troublesome due to the large opening/closing lid that is not easy to open and close at the entrance. Further, since it was necessary to manually measure the amount of finishing agent to be added using a cup or the like, the work involved in adding the finishing agent was troublesome in this respect as well.

The present invention has been made to eliminate the above-mentioned drawbacks, and its purpose is to easily return the processing agent input container from the input position to the input standby position on the operation panel, and to make it possible to easily return the processing agent input container from the input position to the input standby position. It is an object of the present invention to provide a processing agent charging device for a washing machine, etc., in which a fixed amount of processing agent can be supplied to a processing agent charging container in connection with the above-mentioned return operation, and the preparatory operation related to automatic charging of the processing agent is simplified overall.

It is a water guide wall protruding into the water injection chamber 19 of No. 6,
The water thus received is caused to flow into the treatment agent input container 25 at the input position as shown by an arrow 37 through a water flow gap 36 formed between the partition wall 18 and the partition wall 18. Another water guide wall 39 is provided protruding into the processing agent charging container 25 so as to guide the water that has flowed in further into the processing agent charging container 25 as shown by an arrow 38. The inside of the processing agent input container 25 is cleaned. Further, as will be understood from the description below, when the processing agent input container 25 is rotated to the input position, the processing agent inside is released from the discharge end 26 into the storage chamber 20, and the released processing agent is indicated by the arrow 4. The water filling chamber 19 and the storage chamber 20 are communicated with each other through a passage 41 at the front portion thereof so that the water flows as shown in FIG. . Next, the lock mechanism 42 will be described. That is, two gum protrusions 43 and 44 corresponding to the so-called standard course and the saving course are formed on the outer periphery of the cam 11, and the cam 11 is operated so as to be pressed and rotated by the cam protrusions 43 and 44. A boss 46 is provided approximately in the middle of the rod 45 protruding from the back surface of the operation panel 6.
The operating rod 45 is rotatably supported by a tension spring 47 at all times in the holding direction indicated by an arrow 48 to a position where it abuts against a stopper 49. An engaging claw portion 51 is formed at the lower end of the operating rod 45 to engage and disengage an engaging protrusion 50 formed on one side of the processing agent input container 25, and the processing agent input container 25 is approximately opened by the engagement. It is designed so that it can be held in a horizontal loading standby position. Reference numeral 52 denotes an operation lever that is a moving member for operation, and a pivot hole 53 having an intermediate portion thereof, and a through hole 5 at the tip of a pair of supports 54 protruding from the operation panel 6 so as to straddle the slit 15.

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. "Low water level", "Medium water level", "High water level" in the agent supply area C part
characters are displayed. Now, the operating lever 52 has a pressing portion 5 extending upward from the pivot hole 53 position.
9, and an extending piece 61 extending in an arc shape from an engaging end 60, which is the lowermost end. This operating lever 52 also forms one interlocking mechanism 62 with the receiving protrusion 27 of 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.
It is supported at the upper part of the inside, and there is a refill port 65 inside.
Finishing agent is stored by supplying from.
66 is a cap provided in the replenishment port 65. 6
7 is a processing agent supply device, which includes a cylinder 68 and a piston 6.
9, which is attached to the back surface of the operation panel 6 in an inclined manner with screws. An inlet 70 formed at the upper part of the cylinder 68 is communicated with the bottom of the processing agent storage tank 64 , a discharge port 71 formed at the lower part is connected to one end of a tube 72 , and the other end is connected to the bottom of the processing agent storage tank 64 . After passing through a position higher than the maximum liquid level, the processing agent input container 2
5, facing from above. The piston 69
A liquid passage hole 74 having a check valve 73 is formed in the cylinder 67, and a pressure receiving member 76 is attached to the tip of a piston rod 75 passing through the end wall of the cylinder 67. A compression coil spring 77 interposed between the piston 69 and the end surface of the cylinder 67 constantly urges the piston 69 to move toward the suction hole 70 . In this state, the pressure receiving member 76
is opposed to the pressing portion 59 of the operating lever 52.

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. In this state, in order to automatically add a treatment agent, such as a finishing agent, in the current washing operation, move the operating lever 52 to the original position A.
From there, a setting operation may be performed to rotate it to a position corresponding to the water level in the rotating tank 4, which is a washing tank, among "low water level", "middle water level", and "high water level", for example, "high water level". This will be explained in detail below.
When it rotates counterclockwise from the original position A to the terminal end D of the container return area B, its engaging end 60 engages the processing agent input container 25 with its receiving protrusion 27 as indicated by the two-dot chain line E in FIG. As the treatment agent input container 25 is rotated clockwise by contacting each other, the engagement between the engagement protrusion 50 and the engagement claw 51 of the operating rod 45 is finally restored and the treatment agent input container 25 is ready for input. held in position. While the operating lever 52 is rotated clockwise from this state to the "high water level" in the processing agent supply area C as shown by the two-dot chain line F in FIG. The piston 69 is connected to the discharge port 71 of the cylinder 68 via the member 76.
Since the finishing agent is pressed and moved in the direction, a certain amount of finishing agent corresponding to one stroke of the piston 69 is supplied from the cylinder 68 through the discharge port 71 and the tube 72 into the processing agent input container 25. In this case, when the operating lever 52 rotates within the processing agent supply area C as described above, the extending piece 61 integrated with the operating lever 52 simply touches the arcuate surface 28 of the receiving protrusion 27 in the processing agent input container 25. It only slides,
This prevents the processing agent input container 25 from further rotating clockwise. In addition, by rotating the operating lever 52 from the original position A to the "high water level" position all at once as described above, the processing agent input container 25 is returned to its original position and a certain amount of automatically measured amount is processed. The processing agent is supplied, but when you release the operating lever 25, it is automatically returned to the original position A by the tension spring 63, and the engaging end 60 is separated from the receiving protrusion 27, so that the processing agent input container is removed. 25 is no longer prevented from rotating counterclockwise by the operating lever 52. Now, the washing operation is started in the above state, and when it moves to a predetermined process, for example, the final rinse process, the water supply valve 12 is of course operated at this time, but the operating rod 4
5 is caused by the cam protrusion 44 of the cam 11 to the opposite arrow 48
As the treatment agent charging container 25 is pressed and rotated in the direction shown in FIG. The finishing agent inside is released by rotating, and this is finally sent from the water inlet part 24 to the rotating tank 4.
The so-called automatic injection of the finishing agent is completed.

Regarding the above, if the operating lever 52 is rotated to the "medium water level" or "low water level" position, the stroke of the piston 69 will change depending on the magnitude of the rotation angle, so the amount of water that depends on the water level will change. The finishing agent is automatically supplied into the processing agent input container 25.

Next, another embodiment of the present invention will be described with reference to FIG. 11, in which the same parts as in FIG. 10 are denoted by the same reference numerals. The processing agent supply device 78 of this embodiment is provided with two pistons 79 and 80 facing each other in the cylinder 68, and the processing agent storage tank 64 is disposed between the pistons 79 and 80 at the non-supply position shown by the solid line. Both pistons 79 and 8 receive the finishing agent and are pushed to the supply position shown by the two-dot chain line.
A certain amount of finishing agent between 0 and 0 is naturally discharged from the discharge port 71 through the tube 81 into the processing agent input container 25, and there is no need to locate the middle part of the tube 81 at a high place. .

In particular, in any of the above-mentioned embodiments, the finishing agent may be measured by rotating the operating lever back and forth within the processing agent supply area and by the number of times the control lever is rotated back and forth within the processing agent supply area.

In the above embodiment, the treatment agent input container is rotated to the input position by its gravity, but it may also be rotated by a spring means. Also, the release of the holding in the lock mechanism may be performed using a timer. Although this is done by interlocking cams, it may alternatively be done by electromagnets. Furthermore, it goes without saying that the concept of the processing agent includes detergent.

As can be understood from the above description, the present invention includes rotating and returning a processing agent input container from an input position to an input standby position after inputting the processing agent, and processing the processing agent input container that has returned to the input standby position. Supplying a new fixed amount of processing agent can be completed by simply moving the operation moving member on the operation panel from its original position through the container return area to a predetermined position within the processing agent supply area. This makes it possible to perform preparatory operations for automatic processing agent injection extremely easily.
