Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a washing tank with a washing nozzle inside, and a lid back plate that covers the front opening of the washing tank so that it can be freely opened and closed using a shaft provided on the lower end side as a fulcrum, and is located substantially horizontally in the open state. This invention relates to a dishwasher equipped with a lid having a lid and a dish basket that is removably inserted into the washing tank and can be placed on the lid back plate in a pulled-out state, and the load of the dish basket is lower than that of the dish basket. Even if it is intensively applied to the lid back plate through the running pieces provided on both sides,
This prevents deformation such as denting of the lid back plate.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In Figures 1 to 5, 1 is the main body of the dishwasher, 2 is the washing tank installed in the main body 1, and 3 is the main body of the dishwasher.
is a pump that circulates cleaning water, and pump motor 4
Rotationally driven by. The discharge port side of the pump 3 faces into the cleaning tank 2 from the center of its bottom, and a lower nozzle bearing 5 is fixed to this discharge port side from inside the cleaning tank 2. 6 is a lower washing nozzle supported by a bearing 5 for the lower nozzle, and 7 is a lower tableware basket disposed directly above the lower washing nozzle 6.

8 is a discharge hose for the upper nozzle, which is led to the upper surface of the cleaning tank 2. A tower nozzle 9 is fixed to the tableware basket 10. Reference numeral 11 denotes an upper nozzle bearing, which rotatably supports the upper cleaning nozzle 12.

Reference numeral 13 denotes a lid body that covers the front opening of the cleaning tank 2 so that it can be opened and closed, and is a front-opening type supported by a shaft 20 provided on the lower end side. It has 14.

Reference numeral 15 denotes top support rods protruding from both sides of the lower tableware basket 7, and is formed of a horizontal portion 15a and a vertical portion 15b. The tip of the vertical portion 15b of this top support rod 15 serves as a tip insertion portion 16 into which the top shaft 17 is inserted. This distal end insertion portion 16 is directed diagonally downward. That is, it is inclined downward by the dimension A with respect to the horizontal plane. 18
The running top rotates around the top shaft 17 and rolls on a guide 2a on the inner surface of the cleaning tank 2.
Reference numerals 19 and 19 designate a pair of protruding guides provided on the lid back plate 14 on the left and right sides. This is a protruding guide. These protruding guides 19, 19 connect the lower tableware basket 7 to the lid back plate 14.
A circumferential corner portion 18a on the outer surface side of the top 18, which is located outside the running surface of the top 18 when pulled upward.
substantially corresponds to the root corner portion 19a.

In the above configuration, the operation will be explained next. First, regarding the conventional structure shown in FIG. 6, as shown in FIG. 6A, when there is almost no load from the tableware, the tip insertion portion 16' is in a horizontal state. When the tableware load is applied in the direction of the arrow X, as shown in FIG.
6' is deformed, and the rolling contact position between the lid back plate 14 and the running top 18 is at a location away from the protrusion guides 19, 19 and at the circumferential corner 18b on the inner side of the running top 18. , the surface of the lid back plate 14 is deformed into a concave shape a. A countermeasure would be to increase the thickness of the lid back plate 14, but the lid back plate 14 is generally formed of a metal plate, which increases the cost and the weight of the lid body 13, and reduces its pivot support. This raises concerns about the strength of the parts. Moreover, since the weight is large, a problem arises in operability.

However, according to this embodiment, as shown in FIG. 5A, the distal end insertion portion 16 of the top support rod 15 is inclined downward, and when the load of tableware is applied, the tip insertion portion 16 is tilted downward as shown in FIG. Although the distal end insertion portion 16 is deformed, since it is originally inclined downward, it approaches a horizontal state. Therefore, the circumferential corner portion 18a on the outer surface side of the traveling top and the lid back plate 1
Root corner portion 9a of protrusion guide 19, 19 of No. 4
When the root corner part 19a is pressed by the circumferential corner part 18a, the root corner part 19a has no problem in terms of strength due to bending, and there is no risk of deformation. There is no.

In addition, since the running top 18 rotates during running due to the contact of the circumferential corner portion 18a, running performance is improved.

As described above, according to the present invention, top support rods for supporting the traveling top that are inclined diagonally downward are provided on both sides of the tableware basket, and the top support rods for supporting the traveling top are provided on the lid back plate of the front-opening lid. A pair of protruding guides are provided at the base corners located on the outside of the running surface of the top, and correspond to the circumferential corners on the outside surface side of the top. It can prevent the lid back plate from being dented and deformed due to the pressure of the traveling top, and
The structure is such that the top support rod is only slightly inclined, and can be implemented without requiring any special steps or materials.
