Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a treatment agent charging device for a dishwasher.

2. Description of the Related Art In recent years, dishwashers have been widely used, and a treatment agent feeding device is provided to improve washing efficiency.

Heretofore, this type of dishwasher treatment apparatus generally has a structure as shown in FIGS. 7 and 8. As shown in the figure, the main body 1 of the dispenser is attached to the inside of a lid for opening and closing a side opening of the dishwasher, and a detergent reservoir 3 formed by a recess 2 for retaining a detergent and a container for retaining a liquid finishing agent. Consists of four. The recess 2 of the detergent reservoir 3 is covered with a rotating lid 5. In addition, the container 4 is
An inlet 6 for discharging a certain amount of the dry finishing agent stored therein and a replenishing port 7 for replenishing the finishing agent in the container 4 are provided. The refill port 7 is provided with a refill port lid 9 having a transparent remaining amount indicating rod 8 whose tip projects into the container 4 in a substantially conical shape so as to be detachable with a screw.

The operation of the above configuration will be described. The container 4 stores a liquid dry finishing agent in an amount corresponding to 80 to 100 times of the operation of the dishwasher. The remaining amount is determined by a change in the color of the remaining amount indicating bar 8. In other words, when the lid of the dishwasher is opened (FIG. 8), when the remaining amount is large, the tip 10 of the remaining amount indicating rod 8 is in a state of being immersed in a processing liquid such as a dry finishing agent. The incoming light passes through the tip 10 from the remaining amount indicator rod 8 and goes to the dry finish in the container 4, and as a result, it looks dark when looking into the remaining amount indicator rod 8 from the outside.
As the remaining amount gradually decreases and part of the tip 10 begins to be exposed, part of the light that enters from outside reflects off the exposed part of the tip 10 and returns to the outside again. Indicates that the remaining amount indicator rod 8 looks bright.

Problems to be Solved by the Invention In such a conventional processing agent dispenser of a dishwasher, if the amount of light incident on the remaining amount display rod 8 is not large, the light is reflected at the tip 10 and the remaining amount display rod 8 does not look bright. However, in a normal kitchen in which a dishwasher is installed, there is a problem that it is very difficult to see the difference in color between the remaining amount indicating rod 8 when the processing liquid remains and when it is not. Also, after the remaining liquid level falls below the conical tip 10, the periphery of the remaining amount indicator rod 8 starts to change to a bright color, but the length of the tip 10 is short, and furthermore, the tip 10 is reduced due to surface tension. However, there is also a problem that the level of the remaining amount is very difficult to understand because the central portion looks dark until the liquid leaves the liquid surface.

Recently, there has been a demand that a small-sized dishwasher called a table-top type be provided with a finishing agent feeding device, and that the capacity of the dishwasher be increased by enlarging the inside thereof. As for the built-in type that is built into the system kitchen, there is a strong demand for a dishwasher lid that is compatible with the system kitchen, which is generally around 20mm. . In order to realize these demands, it was necessary to make the lid of the dishwasher thin so as not to affect the number of stored dishes, that is, to make the detergent and drying finish feeding device thinner. . However, if the container 4 in which the dry finish is stored in the conventional configuration is thinned while the capacity thereof is kept as it is, the bottom area of the container 4 becomes large, and the remaining amount when the remaining amount indicator rod 10 is empty is reduced. There was a problem of becoming very large.

An object of the present invention is to solve the above-mentioned problem, and to make it easy to recognize the remaining amount of the finishing agent even in a thinned container, to smoothly operate the float, and to improve the reliability.

Means for Solving the Problems In order to achieve the above object, a first object of the present invention is to provide a lid which forms one side wall of a washing tank and keeps a horizontal position when opened, and a lid inside the lid. A container accommodating the attached flat processing liquid, a processing liquid input portion and a discharge port provided on a surface of the container facing the cleaning tank, and a processing liquid remaining amount display portion provided; Is composed of a transparent member facing the cleaning tank, a guide groove inclined with respect to the surface of the transparent member, and communicating with the processing liquid storage portion, and a display float movably provided in the guide groove. And
A second means for solving the problem is that the remaining amount display section has a concave portion on the inclined surface.

Operation In the above-described configuration, the operation 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 is leveled even though the lid has a flat shape. In the state, the length of the display can be sufficiently taken, and the remaining amount can be seen in a wide range. The operation of the second problem solving means is that the concave portion is provided on the inclined surface. The contact area between the float and the float is reduced, and the float can be moved smoothly without being sucked when the float moves.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
