[0019]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0020]
(Example 1)
As shown in FIG. 1, the dishwasher main body 8 has a washing tank 9 provided therein, and the washing tank 9 has a dish basket 10 arranged therein. The cleaning tank 9 has an opening 11 in the front, and is configured to be opened and closed by an upper door body 12 and a lower door body 13. An upper support member 14 is fixed to the upper door body 12, and the upper support member 14 is rotatably supported on a base member 16 by an upper fixed pivot 15. A lower support member 17 is fixed to the lower door body 13, and the lower support member 17 is rotatably supported on the base member 16 by a lower fixed pivot 18. When the doors (the upper door 12 and the lower door 13) are closed, the lower door 13 is made larger in the vertical direction with respect to the upper door 12, and when the door is opened, the lower door 13 is raised. It protrudes forward with respect to the door body 12.
[0021]
The base members 16 are fixed to left and right outer wall surfaces of the cleaning tank 9, respectively. Further, an interlocking link 19 is provided as an interlocking means for interlocking the upper support member 14 and the lower support member 17, and the upper link member 20 and the lower link shaft 21 support the upper support member 14 and the lower support member 17 respectively. The upper door body 12 and the lower door body 13 are prevented from contacting each other during the opening / closing operation. The base member 16, the upper support member 14, and the lower support member 17 are provided on both left and right sides of the cleaning tank 9.
[0022]
The upper fixed pivot 15 is located above the opening 11 of the cleaning tank 9 so that the upper door body 12 rotates and the inner surface side is upward, and below the opening 11 of the cleaning tank 9 when it is horizontal. Are placed. When the door is opened, the lower fixed pivot 17 is moved from the upper door body 12 at the time of opening so that the lower door body 13 overlaps below the upper door body 12 with the inner side facing upward as shown in FIG. It is located below.
[0023]
Further, the base member 16 is provided with a stopper portion 22 such that the inner surface side of the upper door body 12 is lower than the opening 11 of the cleaning tank 9 provided in the cleaning tank 9 when the door body is open.
[0024]
At the lower end of the upper door body 12, a guide portion 23 is provided near the front lower end of the tableware basket 10 when the door is open, and an exhaust port 24 for discharging steam is provided at the upper portion.
[0025]
A seal member (not shown) having an elastic body is provided for the seal between the lower door body 13 and the upper door body 12 and the opening 11, and the seal between the lower door body 13 and the upper door body 12.
[0026]
The handle 25 is operated when the door is opened or closed, and is provided near the upper end of the lower door 13. The latch 26 locks the door body to the dishwasher body 8 and is provided on the lower door body 12, and the lower door body 12 projects forward with respect to the upper door body 13 when the door body is opened. Provided in space.
[0027]
The operation of the above configuration will be described. The upper door body 12 and the lower door body 13 are both opened and closed downward by the upper support member 14 and the lower support member 17, respectively. By the rotation, both the upper door body 12 and the lower door body 13 are turned downward with the inner side facing upward from the opening 11 of the cleaning tank 9.
[0028]
At this time, since both the upper door body 12 and the lower door body 13 open and close downward, an installation space above the dishwasher main body 8 is not required, and therefore, as shown in FIG. Is eliminated, so that installability can be improved. In addition, depending on the strength of the top surface of the dishwasher main body 8, it is possible to effectively use the dishwasher, such as placing objects.
[0029]
In addition, the front of the dishwasher main body 8 occupies half the installation space required for the conventional one-piece door body. Therefore, as shown in FIG. 3, even if the sink 28 is installed horizontally, it is possible to reduce the possibility of blocking the sink 28.
[0030]
In addition, since the upper door body 12 and the lower door body 13 are both below the opening 11 at the time of opening, the opening 11 is large, and can accommodate tableware of substantially the same size as the opening 11, Compared with the conventional one in which the upper door body is located in the middle of the opening, the size of the dishwasher main body 8 can be reduced while securing the size of the tableware that can be accommodated, thereby improving the installation property. can do.
[0031]
Further, when the upper and lower doors are opened, the lower door 13 is configured to protrude forward with respect to the upper door 12, so that it is easy to operate the lower door 13 to open and close the doors. Since the door body 12 is small, it is possible to eliminate a feeling of oppression when the upper door body 12 largely moves from the upper part to the lower part of the dishwasher main body 8.
[0032]
Further, since the handle 25 is provided near the end of the lower door body 13, workability when opening and closing the door body can be made extremely good.
[0033]
The latch 26 is located in a space where the lower door body 13 projects forward with respect to the upper door body 13 when the door body is opened, and the upper door body 13 and the lower door body 12 when the door body is opened. Can be reduced in the vertical direction, the size of the lower part from the lower door body 12 can be reduced, and a compact dishwasher can be realized.
[0034]
(Example 2)
As shown in FIG. 4, the upper door body 29 and the lower door body 30 are configured to open and close the opening 11 in front of the cleaning tank 9, and the upper door body 29 and the lower door body 30 have substantially the same dimensions. As shown in FIG. 5, when the doors (the upper door 29 and the lower door 30) are opened, the lower door 30 is configured to protrude forward with respect to the upper door 29. Specifically, this is realized by providing a lower fixed pivot 18 for determining the opening locus of the lower door body 30 in front of the dishwasher main body 8. The other configuration is the same as that of the first embodiment, and the same reference numerals are given and the description is omitted.
[0035]
Thereby, the usability when operating the lower door body 30 to open and close the door body is improved, and since the upper door body 29 and the lower door body 30 have substantially the same dimensions, the drawer basket 10 for accommodating the tableware is drawn out. The amount can be increased, and the setting property of tableware can be improved.
[0036]
【The invention's effect】
As described above, according to the first aspect of the present invention, the upper door body and the lower door body are configured so as to be overlapped and opened at the lower end side of the opening of the cleaning tank, and the door body is opened. At the time, the lower door body is configured to protrude forward with respect to the upper door body, so that it can be accommodated without blocking the space in front of and above the dishwasher main body and without increasing the size of the dishwasher main body. The size of the dishes can be ensured, and the installation space can be improved by eliminating the need for a space above the dishwasher body, so that the lower door body can be moved forward with respect to the upper door body when the door is opened. , It is possible to improve the usability when the lower door body is operated to open and close the door body.
