A lid portion 5 for closing the front surface is a detergent / drying agent charging device, which comprises a detergent reservoir 57 formed by a concave portion 56 and a container 58 for storing a dry finishing agent. An opening / closing lid 59 that rotates so as to cover is provided, and the container 58 has a storage port 60 for storing a dry finish.
And a reservoir cap 61 for covering the same, and a dry finishing agent inlet for feeding a predetermined amount of the dry finishing agent into the cleaning tank 1.
62 are provided. And, in order to make the remaining amount of the dry finish in the container 58 externally visible, the storage cap 61 has a transparent and substantially cylindrical remaining amount indicating portion 64 with a thinned end portion 63 provided at the center. ing. 6 is a heater.

Next, the operation of the above conventional example will be described. The operation of the dishwasher proceeds in the order of pre-washing, washing, rinsing, heating rinsing, and drying. First, after storing the dishes, the user puts a predetermined amount of powder into the recess 56 of the detergent reservoir 57. After putting the detergent in a shape, the opening / closing lid 59 is closed and the lid 4 of the dishwasher is closed, and then the dishwasher is operated. When the cleaning process is started, the opening / closing lid 59 is opened, and the detergent in the concave portion 56 is dissolved in the water jetted from the cleaning nozzle 3 to become cleaning water. Then, after being heated to a predetermined temperature by the heater 6 in the heating and rinsing step, a predetermined amount of the dry finish is introduced into the cleaning tank 1 through the dry finish inlet 62. By the way, in the container 58, an amount of liquid dry finishing agent corresponding to 80 to 100 times of the operation of the dishwasher is stored,
The remaining amount is determined by a change in the color of the remaining amount display section 64. In other words, when the remaining amount is large, the leading end 63 of the remaining amount display portion 64 is in a state of being immersed in the drying finish, so that light entering from outside passes through the leading end portion 63 from the remaining amount display portion 64 and is dried in the container 58. As a result of going to the finishing agent, it looks dark when looking into the remaining amount display portion 64 from outside. When the remaining amount gradually decreases and part of the tip 63 begins to be exposed, part of the light that has entered from the outside
As a result, the user sees the remaining amount display portion 64 in a bright color as a result of being reflected at the exposed portion and returning to the outside again.

(Problems to be Solved by the Invention) Recently, there has been a demand for providing a detergent and a dry finish to a small dishwasher called a desktop type, and also to increase the number of containers by expanding the inside of the dishwasher. Therefore, it is necessary to reduce the thickness of the detergent and the dry finish. However, if the container 58 in which the dry finishing agent is stored in the conventional configuration is left as it is and the thickness is reduced, the bottom area of the container 58 becomes large, and the remaining amount when the remaining amount display portion 64 is empty is extremely low. There was a problem of becoming large. Even if only the vicinity of the remaining amount display portion 64 is deepened, the space obtained by multiplying the depth by the depth and the bottom area of the container 58 is reduced, so that the conventional remaining amount display method cannot respond to thinning after all. was there.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a thinner detergent / drying agent feeding device.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a lid that closes a front surface of a washing tub of a dishwasher and opens and closes around a bottom side as a rotation axis, and is attached to the lid. A container for storing a liquid detergent or a dry finish, a charging mechanism for discharging a certain amount of the detergent or the dry finish from the container,

Is located below the container when the container is closed, and has an inflow port into which the detergent or the dry finish in the container flows, and stores the flowed detergent or the dry finish when the lid is opened. It is like that.

(Operation) Therefore, according to the present invention, when the lid of the dishwasher is closed, the remaining amount display portion is located below the container, and even when the remaining amount of the dry finishing agent is small, the reservoir portion has the lid portion. It is located below the container when it is closed, and has an inflow port for the detergent or dry finish in the container to flow in. When the lid is opened, store the detergent or dry finish that has flowed in. Can be. For this reason, it is possible to display the remaining amount corresponding to an extremely small amount of remaining amount, and to cope with a reduction in the thickness of the detergent / drying agent input device.

(Embodiment) FIG. 1 shows a detergent / dry finishing agent feeding device according to one embodiment of the present invention, and FIGS. 2 and 3 show containers of the detergent / dry finishing agent feeding device of FIG. It shows a cross section. The overall structure of the dishwasher is the same as that shown in FIG. In FIGS. 1 to 3, reference numeral 11 denotes a detergent / dry finishing agent charging device attached to the inside of a lid portion 4 (FIG. 4) of a dishwasher, 12 denotes a detergent reservoir having a concave portion for storing detergent, 13 Is an opening / closing lid that rotates so as to cover the detergent reservoir 12, 19 is a container for storing a liquid dry finishing agent, 20 is a storage port for storing the dry finishing agent in the container 19, and a stopper is closed by a storage port cap 21. Have been. Reference numeral 22 denotes a measuring chamber for measuring a predetermined amount of the dry finish, reference numeral 23 denotes a guide plate provided to incline above the container 19 toward the measuring chamber 22, and reference numeral 24 denotes the inlet 25 for the dry finish from the measuring chamber 22. Is a valve body provided in the charging path 24,

Reference numeral 30 denotes a substantially cylindrical transparent remaining amount display portion provided at the lower portion of the container 19 and having a thin tip portion 31. Reference numeral 32 denotes a wall member projecting from the bottom portion 33 of the container 19 so as to surround the remaining amount display portion 30. , 34 is a gap, 35 is a cup part,
36 is the lower surface of the container.

Next, the operation of the detergent / dry finishing agent feeding device configured as described above will be described. In the above embodiment,
The container 19 stores a dry finish necessary for 80 to 100 times of the number of times of operation of the dishwasher. The user opens the lid 4 of the dishwasher, stores the dishes, puts a predetermined amount of powdered detergent into the detergent reservoir 12, closes the opening / closing lid 13, closes the lid 4 of the dishwasher, and operates. Start. The dishwasher proceeds in the order of pre-washing, washing, rinsing, heating rinsing, and drying. In the washing process, first, the opening / closing lid 13 is opened and washing is performed. And in the heating rinsing step,
The solenoid 29 is energized for a certain period of time, and the valve 26 opens the charging path 24 so that the dry finish in the measuring chamber 22 flows out from the charging port 25. The operation of flowing the dry finish into the measuring chamber 22 is performed by first opening the guide plate 23 when the lid 4 of the dishwasher is opened.
When the lid 4 is closed, the dry finish agent between the container and the container 19 rises when the cover 19 is closed, flows down along the guide plate 23 into the measuring chamber 22, and a predetermined amount of the weighing agent is measured.

By the way, the display of the remaining amount of the dry finish in the container 19 is determined by the change in the color of the remaining amount display portion 30 when the user opens the lid 4 of the dishwasher. That is, when the distal end portion 33 of the remaining amount display portion 30 is immersed in the dry finish, light from the outside passes through the distal end portion 33 to the dry finish, so that the remaining amount display portion 30 looks dark. When the tip 33 gradually begins to be exposed from the liquid surface, a part of the light entering from the outside is reflected at the exposed portion and returns to the outside again, so that the remaining amount display portion 30 looks bright. In this embodiment, even when the container 19 is thin and the remaining amount of the dry finish is small, the dry finish is filled in the gap 34 between the remaining amount display portion 30 and the wall member 32 when the lid 4 of the dishwasher is closed. It can be stored (Fig. 2). Even when the lid 4 is opened, the dry finish that has accumulated in the gap 34 is removed from the wall member 32 and the container 19.
Remains in the cup portion 35 formed by the bottom portion 33. As described above, the capacity near the remaining amount display unit 30 below the container 19 when the lid unit 4 is closed is reduced, and the lower surface portion of the container 19 is reduced.
If the bottom of 36 is tilted up, even if the remaining amount of the dry finish becomes extremely small, the presence or absence of the remaining amount can be confirmed on the remaining amount display section 30.
