Problems to be Solved by the Invention In such a conventional finisher charging device for a dishwasher, there is a problem that the amount of the processing agent charged can be set in only two stages. That is, in general, the standard amount of a treatment agent, for example, a dry finish agent, is determined according to the amount of water used in the dishwasher. Therefore, it is necessary to change the volume of the measuring chamber according to the capacity (model) of the dishwasher, Since the drying performance is improved by increasing the input amount of the processing agent, there is a demand that the user wants to set the input amount arbitrarily within a certain range.

In addition, there is a demand that a small-sized dishwasher called a desktop type be provided with a finishing agent feeding device, and that the capacity of the dishwasher be increased by enlarging the inside thereof. In addition, as for the built-in type, which is built into the system kitchen, there is a strong demand to attach a decorative plate corresponding to the system kitchen to the lid of the dishwasher, and this decorative plate is generally around 20 mm. is there. In order to fulfill these demands while maintaining the amount of tableware to be stored, it was essential to make the lid of the dishwasher thin.

The present invention solves the above-mentioned problems, and can set the weighing of the treatment agent in multiple stages arbitrarily even in a thinned container, improving the processing accuracy, and providing a highly reliable finisher feeding device for a dishwasher. It is intended to provide.

Means for Solving the Problems In order to achieve the above object, the present invention has a first problem solving means which is formed on one side of a cleaning tank, and which is tilted forward when opened with a lower piece as a rotation axis so that a horizontal position is obtained. A container for holding the eccentric treatment agent mounted inside the lid, a main body provided on the lid so as to expose one side wall of the container to the inside of the cleaning tank, and A measuring chamber comprising a substantially cylindrical wall provided in the container for measuring and storing a treatment agent such as a finishing agent, and a substantially cylindrical adjusting shaft rotatably provided in the measuring chamber; Has a stepped cutout on the circumference of the adjustment shaft corresponding to the measurement scale provided on the surface of the main body, and aims at the processing agent in the container in conjunction with the opening and closing operation of the lid. The second means for solving the problem is to introduce a treatment agent into a container from a measuring chamber into a cleaning tank. An inlet path is provided, and ribs for bonding are arranged around the metering and charging path with a gap therebetween, and the container and the main body are welded by the rib. Further, the rib provided around the charging path has a closed space, and a communication hole that opens outward from the closed space is provided.

Operation The operation of the first means for solving the problems described above has a stepped notch provided on the circumference of the adjustment shaft, so that the adjustment can be adjusted stepwise by rotating the adjustment shaft in accordance with the weighing scale. ,
The operation of the second means for solving the problem is that the joining rib has a gap around the measuring chamber and the charging path, so that the resin melted during welding adheres to the gap and enters the measuring chamber. Intrusion can be prevented, and the effect of the third problem solving means is that compressed air or the like is blown from the communication hole to check the airtightness of the closed space formed by the ribs and to inspect welding. It is assumed that.

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

As shown in FIG. 2, the dishwasher includes a washing tank 14 for storing dishes 15 and storing washing water at the bottom, a washing pump 16 for sending washing water to a washing nozzle 17 and jetting toward the dishes 15 and a washing tank 14. It is constituted by a lid 19 forming one wall surface.
The main body 18 of the processing agent introducing device is attached to the inside of the lid 19, and the container 20 for storing the liquid dry finish is provided with a welding rib 21 of the main body 18 as shown in FIGS. Are welded on the outer peripheral end face 22 of the rim. The replenishing port 23 for charging the processing agent into the container 20 is closed by a replenishing palate 24. The measuring chamber 25 is a cylindrical rib provided on the main body 18.
26 and a semicircular inner wall 27 provided in the container 20
As shown in FIGS. 6 and 7, the adjusting shaft 28 is provided with a notch 30 so that the ridge portion 29 is horizontal or mountain-shaped over the entire circumference. inner wall
It is rotatably supported by 31 via an O-ring 32. FIG. 1 is an exploded view of the treatment agent introduction device, in which a welding rib 21 and an outer peripheral end face 22 are welded on the outer periphery of a main body portion 18 and a container portion 20 and a peripheral portion from a measuring chamber 25 to an introduction port 33 is formed. ,
It is welded at the welding part 40 on the container part 20 side and the welding part 40 (rib shape) on the main body part 18 side. As shown in FIG. 8, the charging path 34 extending from the measuring chamber 25 to the valve body 46 is connected to the end face 36 of the rib 35 and the main body 18.
A welding portion 40 is provided outside the rib 35 with a gap 38 interposed therebetween. In the welding portion 40, a closed space 39 is formed by making the main body 18 into a rib shape. As shown in FIG. 7, a gap 37 is provided below the rib 26 supporting the adjustment shaft 28, and a closed space 39 is similarly formed in the welded portion 40 by making the main body 18 side into a rib shape. ing. Since the closed space 39 is surrounded by the welded portion 40 (rib shape) on the main body 18 side as shown in FIGS. 1 and 5, it becomes a closed space after welding. As shown in FIG. 3 and FIG. 3, a communication hole 41 communicating with the outside is provided on the container section 20 side.

Further, the guide plate 42 is disposed in the container portion 20 so as to be inclined upward from the uppermost portion 43 of the inner wall 27 of the weighing chamber 25, and has a cutout portion 44 on the main body portion 18 side of the uppermost portion 43. Outer wall 45 is weighing chamber 25
The inner wall 27 is inclined downward from the uppermost portion 43 to the outside. As shown in FIG. 4, the valve body 46 is provided in the input path 34, and its periphery is fixed by a cylindrical support member 47. The valve body 46 is pressed against a valve seat 50 via a shaft 49 by a coil spring 48, and is controlled by a solenoid 51. The feeding path 34 is opened and closed by being pulled through the shaft 49.

The operation in the above configuration will be described. The number of times the dishwasher has been operated from 80 to 100
Processing agents such as a dry finishing agent necessary for the batch are stored. As shown in FIG. 2, after the lid 19 of the dishwasher is opened and the dishes 15 are put, the lid 19 is closed and the operation is started. This lid
With the opening and closing of 19, the processing agent feeding device is raised from the horizontal state 18 '. At this time, as shown in FIG. 1, the processing agent accumulated above the measuring chamber 25 and the guide plate 42 when the container 20 is in a horizontal state flows into the measuring chamber 25 along the guide plate 42 and the like. The measuring chamber 25 is provided with a substantially cylindrical adjustment shaft 28,
A metering space 52 formed up to the uppermost part 43 by 30 and the inner wall 27
The processing agent enters the inside, and those exceeding the capacity
From the uppermost part 43 along the outer peripheral wall 45. This metric space
52 is set to an arbitrary volume according to the position in the rotation direction depending on the shape of the cutout portion 30 of the adjustment shaft 28, and a user can select a desired input amount by turning the adjustment shaft 28 with the operation unit 53 on the front side.

And the operation of the dishwasher is pre-washing, washing, rinsing,
The heating and rinsing process proceeds in order, but when the temperature of the washing water reaches a predetermined value in the heating and rinsing process, the solenoid
Electric current is supplied to the valve 51 for a certain period of time, and the valve body 46 is pulled, so that the treatment agent in the measuring chamber 25 flows out of the charging port 33 through the charging path 34.

Incidentally, welding using a hot plate or the like is often used as a method of stabilizing the sealing state and reducing the number of steps during mass production. Also in this embodiment, as shown in FIGS. 7 and 8, the outer periphery of the container section 20 and the main body section 18 as well as the measuring chamber 25, the charging path 34, and the charging port 33 are welded. Resin burrs accumulate and adhere to the surrounding gap 37 in the measuring chamber 25, so that burrs do not enter the measuring chamber 25. Similarly, the rib 35 of the container section 20 comes into contact with the main body section 18 and dams the burrs in the charging path 34. For this reason, the rotation of the adjustment shaft 28 is not hindered by the burr, and the cross-sectional area of the charging path 34 is always uniform.

Further, it is necessary to inspect all products in order to completely guarantee the liquid leakage from the welding portion, but an air leak test is generally used as an inspection method. That is, air at a constant pressure is sent from the replenishing port 23, pressurized and held for a certain time, and the pressure in the container is measured. If there is a small hole due to poor welding, air leaks from this hole, and the pressure decreases, so that poor welding can be known. However, if there is no closed space 39 and the communication hole 41, the welding portion 40 around the measuring chamber 25 and the charging path 34 cannot be detected even if there is a hole due to poor welding because no air leaks to the outside. It is possible. If there is poor welding in this portion, the dry finish agent accumulated in the measuring chamber 25 leaks into the container portion 20 due to the opening / closing operation of the lid 19 of the dishwasher, so that measurement cannot be performed. That is, if there is a defect in the welding portion 40 in the above-described air leak test, the air leaking into the closed space 39 leaks to the outside via the communication hole 41, and as a result, the pressure is reduced and the welding defect can be detected. In the inspection method in which air is sent from the above-described replenishing port 23, it cannot be determined whether the leakage is at the welding rib 21 on the outer periphery of the container portion 20 or at the internal welding portion 40. If the air leak test is carried out, it is possible to determine whether or not the internal weld 40 is the cause.Moreover, since the ridge 29 of the notch 30 of the adjustment shaft 28 has a mountain shape, the lid 19 of the dishwasher When closed, the processing agent flowing into the measuring chamber 25 does not accumulate in the notch 30 on the upper side of the adjustment shaft 28 and flows down smoothly. Further, the processing agent overflowing from the uppermost portion 43 of the inner wall 27 of the measuring chamber 25 flows smoothly because the outer peripheral wall 45 is inclined, and does not accumulate in this portion due to surface tension. Therefore, the processing agent stored in the measuring chamber 25 maintains a constant ridge and stabilizes the measuring.

The same effect can be obtained as long as the treating agent is a liquid such as a dry finish or a detergent.

As is clear from the above description of the embodiment, according to the present invention, a container containing a flat processing agent mounted inside the lid of the cleaning tank, and a side wall of the cleaning tank forming one side wall of the container. A main body provided inside the lid so as to be exposed to the inside, a measuring chamber provided in the container and having a substantially cylindrical wall surface for measuring and storing the processing agent, and rotatably provided in the measuring chamber. The adjustment shaft has a substantially cylindrical shape, and the adjustment shaft has a configuration in which a notch is provided in a stepwise shape on the circumference of the adjustment shaft corresponding to the design scale provided on the surface of the main body portion, so that the thickness is reduced. Even if a lid is used, it can be arbitrarily weighed according to the application, and the weighing accuracy can be improved.
