Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for dispensing finishing agents, etc., in a dishwasher.

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

Conventional finishing agent injection devices have been constructed as shown in FIGS. 9 and 10. That is, a main body 1 of the finishing agent injection device is attached to a lid (not shown) of a dishwasher, and a container 2 for storing a liquid processing agent is welded to the main body 1 all around. The metering chamber 3 is welded to the main body 1 and includes two cup-shaped chambers, and an input path 4 for guiding the metered processing agent from the metering chamber 3 to the input port 6. It is composed of a valve body e that is biased by a spring 7 to close the input path 4 and is opened and closed by a solenoid 8, an adjustment screw 9 that opens and closes a communication hole 10 that connects one chamber 3-a of the measuring chamber 3 and the input path 4, etc. was.

To explain the operation of the above configuration, approximately 100 d of processing agent such as finishing agent is stored in the container 2, and the loading device makes approximately 900 reciprocating movements as shown by arrow 11 as the lid of the dishwasher opens and closes. (Figure 10 shows the lid closed). At this time, the processing agent accumulated in the measuring chamber 3 or the bottom 12 of the container 2 flows up to the overflow line 13 in a manner that scoops it up, and each part M3-a, 3-b of the measuring chamber 3 is filled with about 0.
4M! Accumulate. The processing agent accumulated in the metering chamber 3 is discharged from the input port 6 through the input path 4 when the valve body 6 is opened. It was decided whether or not to discharge the processing agent accumulated in room 3-a, and adjustments were made in three stages (approximately 0.4 or 0.8111/).

Problems to be Solved by the Invention In such a conventional dishwasher finishing agent feeding device,
There was a problem in that the amount of processing agent to be added could only be set in two stages. In other words, since the standard amount of processing agents, such as drying finishing agents, is generally determined depending on the amount of water used in the dishwasher, it is necessary to change the volume of the measuring chamber depending on the capacity (model) of the dishwasher. Furthermore, since drying performance improves when the amount of treatment agent added is increased, there has been a desire for users to arbitrarily set the amount of treatment agent added within a certain range.

In addition, there is a desire to install a finishing agent dosing device in a small dishwasher called a tabletop type, and to expand the interior of the dishwasher to increase its capacity. Furthermore, regarding the so-called built-in type that is incorporated into a system kitchen, there is a strong demand for a decorative board to be attached to the lid of the dishwasher that is compatible with the system kitchen, and this decorative board is generally around 2o. It is. In order to meet these demands while maintaining the amount of dishes that can be stored, it is essential to make the lid of the dishwasher thinner.

The present invention solves the above-mentioned problems. Even in a thinner container, the amount of treatment agent can be arbitrarily set in multiple stages, improving processing accuracy, and providing a highly reliable finishing agent dosing device for dishwashers. is intended to provide.

Means for Solving the Problems In order to achieve the above object, the present invention has a first means for solving the problems, which includes a flat container for storing a processing agent attached to the inside of the lid of a cleaning tank, and one side wall of the container. a main body part provided inside the lid so as to be exposed to the inside of the cleaning tank; a measuring chamber provided in the container with a substantially cylindrical wall surface for measuring and storing the treatment agent; and this measuring chamber. The adjustment shaft is provided with a substantially cylindrical adjustment shaft rotatably provided on the main body, and the adjustment shaft has stepwise notches on the circumference of the adjustment shaft corresponding to the measurement scale provided on the surface of the main body. In addition, a second means for solving the problem is to provide an input path in the container that leads the processing agent from a measuring chamber into the cleaning tank, and to arrange ribs for joining with gaps around the measuring chamber and the input path, and to The container and the main body are welded together by a method of welding the container and the main body part.A third means to solve the problem is that the ribs provided around the measuring chamber and the input route have a sealed space, and a communication opening from this sealed space to the outside is provided. It has holes.

Function The above-mentioned first problem-solving means has stepwise notches on the circumference of the adjustment shaft, so it is possible to adjust the adjustment stepwise by rotating the adjustment shaft in accordance with the measurement scale. can be,
In addition, the second problem-solving means works because the joining rib has a gap around the measuring chamber and the feeding path, so the resin that melts during welding sticks to the gap and flows into the measuring chamber. In addition, the third problem-solving means works by blowing compressed air through the communication hole to check the airtightness of the sealed space formed by the ribs and inspect the welding. It is possible.

EXAMPLES Hereinafter, examples of the present invention will be explained based on FIGS. 1 to 8.

As shown in the figure, the dishwasher has a washing tank 4 which stores tableware 15 and stores washing water at the bottom. It is composed of a cleaning pump 16 that sends cleaning water into a cleaning nozzle 17 and jets it out toward the tableware 15, and a lid 19 that forms one wall of the cleaning tank 14. A main body 18 of the processing agent injection device is attached to the inside of a lid 19, and a container 20 for storing a liquid dry finishing agent is welded to a welding rib 21 of the main body 18 at an outer peripheral end surface 22. A replenishment port 23 through which a processing agent is introduced into the container 20 is closed by a replenishment cap 24. The measuring chamber 25 has a cylindrical rib 26 provided on the main body 18.
and a semi-cylindrical inner wall 2 provided in the container 20.
As shown in FIG. 6, the adjusting shaft 28 has a cutout 3o on the inner wall of the rib 26 so that the ridgeline 29 is horizontal or mountain-shaped all around. 3

The input port 33 is for discharging a predetermined amount of dry finishing agent into the washing tank 14 of the dishwasher, and the input path 34 is provided from the measuring chamber 26 to the input port 33 via a substantially U-shaped rib 35. , is formed by matching the end surface 36 of the rib 35 and the main body portion 18. A gap 37 is provided around the measuring chamber 26 on the outside of the cylindrical rib 26 on the main body 18 side, and a gap 38 is provided around the rib 35 of the input path 34 to close the closed space 3.
9 is formed, and a welding part 40 is disposed so as to surround the input port 33, and the main body part 18 and the container 2o are welded together at the welding part 40. Note that the container 2o is provided with a communication hole 41 that communicates the closed space 39 with the outside.

Further, the guide plate 42 is located at the top 43 of the inner wall 26 of the measuring chamber 25.
It is disposed in the container portion 2o so as to be inclined upward, and a notch portion 44 is provided on the top portion 43 on the main body portion 18 side. The outer peripheral wall 45 slopes downward from the top 43 of the inner wall 27 of the measuring chamber 25 toward the outside. Valve body 46 is input route 3
4, the periphery is fixed by a cylindrical support member 47, and is pressed against the valve seat 6o via a shaft 49 by a coil spring 48, and is pulled via the shaft 49 by a renoid 51 to open and close the input path 34. It is supposed to be done.

To explain the operation in the above configuration, the number of times the dishwasher is loaded into the container part 2Q from the refill port 23 is 80 to 80.
Processing agents such as drying finishing agents required for 100 times are stored. As shown in FIG. 2, after opening the lid 19 of the dishwasher and putting tableware 15 therein, the lid 19 is closed to start operation. As the lid 19 is opened and closed, the processing agent charging device is raised from the horizontal position 18'. At this time, when the container 20 is in a horizontal state, the processing agent that has accumulated above the measuring chamber 26 and the guide plate 42 flows into the measuring chamber 25 along the guide plate 42 and the like. The measuring chamber 26 is provided with a substantially cylindrical adjustment shaft 28, and the processing agent enters the measuring space 62 formed up to the top 43 by the notch 30 and the inner wall 2a, and the volume is adjusted. Those exceeding this amount overflow from the top 43 of the inner wall 27 along the outer peripheral wall 45. This measurement space 62 is located at the notch 3 of the adjustment shaft 28.
Depending on the shape of the o, an arbitrary volume is set according to the position in the rotational direction, and the user can select the desired amount of input by turning the adjustment shaft 28 using the operating section 63 on the front side.

The operation of the dishwasher proceeds in the order of prewashing, washing, rinsing, heating rinsing, and drying, but when the temperature of the washing water reaches a predetermined value in the heating rinsing process, the renoid 5
