For example, in this type of device in a washing machine, a processing agent storage container is generally provided in an operation box, and a processing agent inlet opening for entering the processing agent storage container from above is formed on the upper surface of the operation box.

[Problems with background technology]

However, in the conventional structure described above, since the processing agent storage container and the inlet body are separated, it is difficult to visually check how much processing agent has accumulated in the container when adding the processing agent, and if too much is added, it overflows. Sometimes I let it come out. In addition, during post-assembly inspections at the factory, whether or not the processing agent storage container was working properly was confirmed by the sound of the container colliding with the bottom of the operation box when it rotated downward; It is not the preferred testing method in large factories.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to easily check the amount of processing agent in the processing agent storage container, and also to be able to check whether the processing agent storage container is operating normally without relying on sound. An object of the present invention is to provide a processing agent charging device for a washing machine or the like that can be easily inspected visually.

[Summary of the invention]

The present invention has a structure in which the inlet body extends downward from the top of the processing agent storage container in the standby position and is positioned within the container, and thereby the processing agent is supplied to the processing agent storage container. J: so that it can be easily recognized by entering the inside of the inlet.

[Embodiments of the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a dehydrating and washing machine will be described below with reference to the drawings. Reference numeral 1 designates an outer box of a washing machine for dehydration and dehydration, which is equipped with a water receiving tank 3 and a rotating tank 2 that also serves as a washing tank. is an operation unit 7 having an internal operation control device 6,
8. Electromagnetic water supply valve whose rear part will be described later. It is an electrical equipment storage part 10 in which a water level switch 9 and the like are installed. Reference numeral 11 designates a bottom plate of the electrical component storage section 10, and a water filling chamber 12 surrounded by ribs 11a is formed on the top surface of the bottom plate, and a water outlet 8a of the electromagnetic water supply valve 8 faces into this water filling chamber 12. In addition, 12a is water injection chamber 1
This is a water inlet for injecting water supplied into the rotating tank 2 into the rotating tank 2. 13 is a porous body provided below the water outlet 8a to weaken the water force. Reference numeral 14 denotes a processing agent storage container with an open top and approximately shaped like the bottom of a ship, and is provided within the water injection chamber 12 on the side of the electromagnetic water supply valve 8. It is rotatably supported by another rib 11b standing between the rib 11a and the electromagnetic water supply valve 8. Reference numeral 15 denotes a projecting piece protruding from the front right side of the processing agent storage container 14, and reference numeral 16 denotes a buzzer fixedly arranged on the outside of the rib 11a, and the buzzer 16 includes a coil 16a and a diaphragm 16b.

The diaphragm 16b of the buzzer 16 has a fixed lower end and a free upper end, and the free end is bent into a substantially "W" shape. In the state shown in FIGS. 3 to 5, the protruding piece 15 of the processing agent storage container 14 is placed on the free end of the diaphragm 16b, thereby locking the container 14 in the horizontal standby position. In this state, when the coil 16a is energized for a short time, the vibration plate 16b is attracted by the magnetic force of the coil 16a and is displaced to the state shown by the two-dot chain line in FIG. is released, and the container 14 pivots downward around the shaft 14a under its own weight, reaching the inclined input position shown by the two-dot chain line in FIG. Reference numeral 17 denotes an inlet body for supplying a processing agent that is integrally formed on the upper surface of the electrical component storage section 10, and its lower end is extended downward from the top of the processing agent storage container 14 in the standby position, that is, the upper end of the opening. Inlet 17
a is located within the container 14 as shown in FIG.

A scale 18 is provided on the inner surface of the lower part of the inlet body 17 located inside the processing agent storage container 14, as shown in FIG. Reference numeral 19 denotes a lid member for opening and closing the upper opening of the input port body 17, and a shaft portion (not shown) protruding from both sides of the rear end is rotatably supported on the rear end of the input port body 17. There is. still,
Although not shown, as a mechanism for returning the processing agent storage container 14 from the loading position to the standby position, a lever is extended to the lid member 19, and a lever receiving portion is formed on the processing agent storage container 14, so that when the lid member 19 is opened. A well-known structure is adopted in which the lever rotates in response to this, and the lever receiver abuts against the part, thereby returning and rotating the processing agent storage container 14 from the input position to the standby position.

Next, the operation of the above configuration will be explained. Now, when operating the operation control device 6 to start the washing operation, the processing agent storage container 1
4 is in a horizontal standby position as shown by the solid line in FIG. 5, and a processing agent such as a soft finishing agent is already stored inside. When the washing operation is started in this state, the processes proceed in order from washing, intermediate dehydration, and intermediate washing, and in each process of washing and intermediate rinsing, the electromagnetic water supply valve 8 is energized, so that water is not supplied to the electromagnetic water supply valve. The water is discharged from 8 into the porous body 13, passes through the water inlet 12 as shown by arrow A in FIG. 3, and is supplied into the rotating tank 2 through the water inlet 12a. Now, when the processing agent is to be supplied into the rotating tank 2 at a predetermined time, for example, in the final rinsing process, the electromagnetic water supply valve 8 is energized and starts supplying water, and the fill 16a of the buzzer 16 is activated for a very short time. Electricity is applied to attract and displace the diaphragm 16b.

As a result, the diaphragm 16b is connected to the protruding piece 1 of the processing agent storage container 14.
5, the container 14 rotates downward due to its own weight from the standby position to the input position shown by the two dots @ line in FIG.
The processing agent inside is discharged into the water injection chamber 12 from its tip. The processing agent discharged into the water injection chamber 12 is dissolved in the water flowing inside the water injection chamber 12 and is supplied into the rotating tank 2 together with the water. After the final step 71-', a final dewatering step is performed, and the operation of the washing machine ends.

Now, in order to supply the processing agent into the processing agent storage container 14 during the next washing, one lid member is rotated in the opening direction. Then,
In conjunction with the rotation of the lid member 19, the processing agent storage container 14 rotates upward and returns to the standby position where the protrusion 15 is placed on the diaphragm 16b. Now, after opening the lid member 19, when the processing agent is injected into the input chamber 17, the processing agent flows down from the lower end injection port 17a of the input port body 17 into the processing agent storage container 14 and is stored therein. Then, due to an increase in the amount of processing agent stored, the liquid level of the inlet body 1 remains within the processing agent storage container 14.
When the lower end of No. 7 is reached, the fourth
As shown by liquid level B in the figure, the processing agent also enters into the input chamber 17.

At this time, the liquid level in the input chamber 17 is the same as the liquid level in the processing agent storage container 14, so by visually observing the liquid level, you can determine how much processing agent is in the processing agent storage container 14. You can easily check whether the agent has been stored. Therefore, the processing agent does not overflow from the processing agent storage container 14, and only the appropriate amount can be injected into the valve at all times.

Also, during factory inspections, for example, water is poured into the inlet body 1.
If you visually confirm that water enters the input chamber 17 by injecting water from 7 and that the water in the input chamber 17 disappears by energizing the buzzer 16, the processing agent storage container 14 is confirmed. Since it means that the product is operating normally, the inspection method is more reasonable than the conventional method of inspecting by sound in a noisy factory, and it is possible to reliably determine whether the product is good or bad.

The present invention may be applied not only to soft finishing agents but also to detergent or bleach dispensing devices, and may be applied not only to washing machines but also to dishwashers.

〔Effect of the invention〕

As explained above, in the present invention, the inlet body extends downward from the top of the processing agent storage container in the standby position and is positioned inside the container, so that when the processing agent is supplied, the processing agent is By visually observing the liquid level of the processing agent that has entered the inlet, the amount of processing agent supplied can be confirmed, preventing the processing agent from overflowing from the processing agent storage container, and preventing the factory from overflowing. An excellent effect is that even during inspections, it is possible to accurately check whether the processing agent storage container is operating normally by visually confirming whether the liquid enters the inlet body and disappears when liquid is injected. It is something that plays.
