DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples embodying the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention. It should be noted that the following examples are examples of embodying the present invention, and are not intended to limit the technical scope of the present invention. Here, FIG. 1 is a schematic cross-sectional view showing the internal structure of a dishwasher according to an embodiment of the present invention, FIG. 2 is an explanatory view showing the detailed structure of the section viewed from arrow C in FIG. 1, and FIG. It shows the structure of the main part of the tableware storage part which comprises a washing machine, (A) is a top view, (B) is a side view. Further, the same reference numerals are used for elements common to those of the conventional dishwasher A shown in FIG. 4, and detailed explanation thereof will be omitted. As shown in FIG. 1, the dishwasher B according to this embodiment has almost the same basic structure as the conventional dishwasher A. The tableware storage section 11 to be placed in the tableware storage section 11 is supported so as to be able to swing up and down in a vertical plane including the direction in which a plurality of supporting sections 11a are arranged in parallel to support the tableware 13. The tableware storage section 11 is tilted in conjunction with the spraying operation. That is, in the dishwasher B according to this embodiment, as shown in FIGS. 1 to 3, a plurality of dishes 13 are installed on the top surface of the dish storage section 11 so that the dishes 13 can be inserted and placed from above in a substantially vertical state. The supporting parts 11a, 11a,
... are arranged in parallel, and one end of the tableware storage section 11 is
It is pivotally supported by the tableware basket 10 so as to be able to swing vertically within a vertical plane including the direction in which the support portions 11a are arranged side by side. By making the support part 11a have the above structure,
The tableware 13 can be easily placed on or taken out from the tableware storage section 11. Above tableware basket 10
The tableware storage section 1 is swingably supported at one end thereof.
1, the tip of a piston rod 15 is engaged with the other end. The piston rod 15 is connected to the cylinder 1
The cylinder 12 is fitted in the inside of the nozzle 2 so as to be slidable in the vertical direction, and the cylinder 12 is connected to the communication pipe 4 that communicates the lower water tank 9 and the nozzle 1 via a communication pipe 14. In dishwasher B configured as above,
During washing, the washing water stored in the lower water tank 9 is fed by the action of the washing pump 3 and is sprayed from the injection hole 2 of the nozzle 1 toward the dishes 13 in the dish basket 10. A part of the pressure water from the cleaning pump 3 is introduced into the cylinder 12 through the communication pipe 14 connected to the communication pipe 4 to the nozzle 1, and the piston rod 15 is pushed up by the action of the water pressure. . As the piston rod 15 rises, the tableware storage section 11 tilts. As the tableware storage section 11 is tilted as described above, the tableware 13 that was supported vertically by the support section 11a of the tableware storage section 11 is also tilted, and the washing water from the injection hole 2 of the nozzle 1 is directed toward the tableware storage section 11. The entire inner surface of the tableware 13 is easily touched. As a result, the cleaning efficiency for the tableware 13 is improved. When the cleaning operation is completed as described above and the cleaning pump 3 is stopped, the water pressure inside the cylinder 12 is reduced. Then, the piston rod 15 contracts downward due to the weight of itself, the tableware storage section 11, and the tableware 13 housed in the tableware storage section 11. As a result, the tableware storage section 11 returns to its original state, and the opening surface of the thread bottom 13a of the tableware 13 stands approximately vertically. As a result, the cleaning water does not stay inside the container and all of it flows down, which greatly reduces the time required for drying. In the above embodiment, the tableware storage section 11 is tilted using the pressure of the washing water supplied by the washing pump 3. The storage section 11 may be tilted.
