Description

[Detailed description of the invention] Industrial applications The present invention relates to a processing agent charging device for a dishwasher.

BACKGROUND OF THE INVENTION In recent years, dishwashers have become widely used, and are equipped with processing agent charging devices to improve cleaning efficiency.

Conventionally, the treatment agent charging device for this type of dishwasher generally had a configuration as shown in FIGS. 7 and 8. As shown in the figure, a loading device main body 1 is attached to the inside of a lid that opens and closes an opening on the side of the dishwasher, and a recess 2 for storing detergent.
It consists of a detergent reservoir 3 and a container 4 for storing a liquid finishing agent. The recess 2 of the detergent reservoir 3 is covered with a rotating opening/closing lid 6. Additionally, the device body 1 has an input port 6 for discharging a certain amount of the dry finishing agent accumulated in the container 4.
A replenishment lower for replenishing the finishing agent is provided in the container 4. This refilling lower has a refilling cap 9 with a transparent remaining amount indicating rod 8 having a substantially conical tip protruding into the container 4.
It is provided so that it can be attached and detached with a screw.

The operation of the above configuration will be explained. The container 4 stores an amount of liquid drying finishing agent equivalent to 80 to 100 operations of the dishwasher, and the remaining amount is determined by the change in color of the remaining amount indicator bar 8. When there is a large amount remaining when the lid of the dishwasher is opened (Fig. 8), the tip 1o of the remaining amount indicator bar 8 is immersed in a processing liquid such as a drying finishing agent, so the external The light entering from the remaining amount indicator rod 8 passes through the tip 10 and goes to the dry finishing agent in the container s, so that when looking into the remaining amount indicator rod 8 from the outside, the color appears dark. When the remaining amount gradually decreases and a part of the tip 1o begins to be exposed, part of the light entering from the outside will be absorbed by the tip 1o.
As a result of being reflected at the exposed area of 0 and returning to the outside,
The user noticed that the remaining amount display bar 8 appeared to be a bright color. .

Problems to be Solved by the Invention In such a conventional dishwasher processing agent dispensing device, if the amount of light incident on the remaining amount display bar 8 is not large, it will be reflected at the tip 1o and the remaining amount display bar 8 will not appear bright. In a typical kitchen where a dishwasher is installed, there is a problem in that the difference in color of the remaining amount indicator bar 8 when there is processing liquid left and when it does not is very difficult to distinguish. In addition, after the remaining liquid level drops below the conical tip 10, the area around the remaining amount display bar 8 starts to change to a bright color, but the length of the tip 1o is short and furthermore, due to surface tension, the tip 1o There was also the problem that the central part appeared dark until it left the liquid surface, making it very difficult to tell how much liquid remained.

Recently, there has been a growing demand for small tabletop dishwashers to be equipped with finisher dispensers, as well as for expanding the interior of the dishwasher to increase its capacity. Furthermore, regarding built-in type dishwashers that are incorporated into system kitchens, there is a strong desire to attach a decorative board to the lid of the dishwasher that is compatible with the system kitchen, and this decorative board is generally around 20 meters long. . In order to meet these demands, it was necessary to make the lid of the dishwasher thinner so as not to affect the number of dishes stored, or in other words, to make the detergent and drying agent dispenser thinner. . However, if the container 4 in which the drying finishing agent is stored in the conventional configuration is made thinner while leaving its capacity as it is, the bottom area of the container 4 will increase and the remaining amount will be smaller when the remaining amount display bar 1o indicates empty. The problem was that there were too many.

The present invention solves the above problems, and aims to make it easier to display the remaining amount of finishing agent even in a thinner container, and to make the movement of the float smoother and improve reliability.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a first problem-solving means: a lid part that forms one side wall of the cleaning tank and maintains a horizontal position when opened; a flat-shaped container for accommodating the processing liquid; an inlet and a discharge port for the processing liquid are provided on a surface of the container facing the cleaning tank; and a remaining amount display section for the processing liquid is provided; comprises a transparent member for the cleaning tank, a guide groove that is inclined with respect to the surface of the transparent member and communicates with the processing liquid storage part, and a display float movably provided in the guide groove. According to the second problem-solving means, the remaining amount display section is provided with a recessed portion on the inclined surface.

Function In the above-mentioned configuration, the function of the first problem solving means is that the float for displaying the remaining amount moves along the inclined surface, so that the processing liquid container can be held horizontally even though the lid is flat. In this state, the display can be sufficiently long.
Because you can see the remaining amount in a wide range, you can also use the second
The effect of the problem solving means is that by providing a recess in the slope, the contact area between the slope and the float is small, and the float can move smoothly without being attracted when moving. EXAMPLES Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 4.

As shown in the figure, the main body of the dishwasher includes a washing tank 11 that stores tableware 12 and collects washing water at the bottom, and a washing bond that sends washing water to a washing nozzle 14 and sprays it toward the tableware 12. and a lid 16 that covers the front opening of the cleaning tank 11. The lid portion 16 is provided so as to be able to be turned upside down, and a processing agent injection device main body 15 is attached to the inside thereof. On the inner surface of the dispenser main body 15, there are a detergent reservoir 17 consisting of a recess 18 for storing detergent, and an opening/closing lid 19 that rotates to cover the detergent reservoir 17. Further, the feeding device main body 15 is provided with a container 20 for storing a processing liquid such as a liquid drying finishing agent, and a replenishment port 21 for introducing the processing liquid into the container 2o.
