A through hole 44c is formed at an appropriate position on the front side of the main body 44a of the side splash prevention member 44, and the shaft portion 36a of the front horizontal rod 36 is inserted into the through hole 44c. The side eaves portion 44b
The rear end portion extends rearward from the rear end portion of the main body 44a, and the extended portion 44d is mounted on the shaft portion 40a of the rear lateral rod 40. A through hole 44e is formed in the extension portion 44d, and a screw 48 inserted into the through hole 44e is screwed into a screw hole 40b provided in the shaft portion 40a of the rear horizontal rod 40, thereby forming the hole. The side splash prevention member 44 is attached to the side of the rack rail 22. The front rail 42 and the both-side rails 44, 44
The main body 44a, 44 of the side water splash prevention members 44, 44 is attached to both ends in the width direction of the front water splash prevention member 42 with the
a is configured to abut.

[0018]

Next, the operation of the dishwasher according to the embodiment will be described below. As shown in FIGS. 1 and 2, each of the shaft portions 40 a of the rear horizontal rod 40 is provided with a rack rail 22 disposed inside the cleaning tank 14.
6 is engaged with the engagement concave portion 30 defined by the rear water splash prevention member 28, and the positioning portion 34b of each of the vertical rods 34 is set in the washing posture in which the positioning portion 34b is placed on the step portion 14b of the washing tank 14. ing. Therefore, tableware (not shown) is attached to the rack rail 22.
Can be placed horizontally.

The washing tank 14 is covered from above by lowering the casing-like lid 16, and surrounds the tableware rack 32 placed on the rack rail 22. Casing lid 1
The washing in the dishwasher 10 is started by the lid 6 and the washing liquid is jetted and supplied from the upper and lower washing nozzles toward the tableware, and rinse water is supplied from the upper and lower rinsing nozzles after the washing is completed. At the front and side portions of the rack rail 22, the front water splash prevention member 42 and the side water splash prevention member 4 are provided.
Since 4,44 is provided, the washing liquid and the rinsing water are prevented from splashing to other than the tableware. Further, the rear water-splash prevention members 28, 28 attached to the left and right supports 26, 26 are provided on both sides of the rack rail 22.
4 and 44, it extends rearward by a predetermined length, and the back splash prevention members 28 also prevent the washing liquid and the rinsing water from splashing. After a predetermined time, the washing and rinsing of the dishes is completed, and the casing-like lid 16 is lifted to raise the washing tank 1.
The tableware washing is completed by opening the tableware 4 and taking out the tableware rack 32 to the outside.

Next, when cleaning the inside of the washing tank 14 or performing maintenance such as inspection of the lower washing nozzle or the lower rinsing nozzle, as shown in FIG. By rotating the hook 24 backward about the center 40a and hooking the hook 24 on the front horizontal rod 36 and holding the hook 24 in the retracted position, the inside of the cleaning tank 14 is opened. In this state, by removing members such as the filter, the overflow pipe, and the slope, cleaning of the inside of the cleaning tank 14 and inspection of the lower cleaning nozzle or the lower rinsing nozzle can be easily performed. In addition, since the front water-stopping member 42 and both-side water-stopping members 44, 44 also rotate integrally with the rack rail 22, the rack rail 22 and the water-stopping members 42, 44, 44 are removed from the cleaning tank 14. There is no need to place it outside, and it is not necessary to search for a place where the rail 22 or the water splash prevention members 42, 44, 44 are placed or to secure a space. In addition, the rack rail 22 and the water-prevention member 4
Since 2,44,44 does not become dirty, it is sanitary.

The rack rails 22 and the water splash prevention member 4
2,44,44 are shaft portions 40a, 40a of the rear horizontal rod 40.
Is simply pulled up from the engagement recesses 30, 30, and the cleaning tank 14
The rack rails 22 and the water splash prevention members 42, 44, 44 can be cleaned externally and can be kept hygienic at all times. Moreover, the rack rail 22
And the water splash prevention members 42, 44, 44 can be integrally handled, so that the number of components to be removed from the cleaning tank 14 during maintenance can be reduced, and the work load can be reduced. Further, it is possible to prevent the water splash prevention members 42, 44, 44 from being lost by being handled alone.

Here, it is necessary to provide a water splash prevention member behind the rotation supporting portions (shaft portions 40a, 40a) of the rack rail 22. In the embodiment, the water splash prevention member 44 is formed separately from the side water splash prevention member 44. After that, a water splash prevention member 28 is attached to the support 26 to cope with the problem. And, in this way, the back-flight preventing member 2
When the rack rails 22 are rotated, the side splash preventing members 44 do not interfere with the inner bottom surface of the cleaning tank 14 when the rack rails 22 rotate. That is, it is possible to cope with this without requiring a change in the design of the bottom of the cleaning tank 14 and the like. In addition, the back-splash prevention member 28 can be removed from the support 26 and cleaned outside.

In the embodiment, a casing-like lid is provided so as to cover the washing tank so as to be able to move up and down from the upper part. In the covered state, a washing chamber is defined inside and the casing-like lid is raised by a required distance. Although a dishwasher of the type which is opened by being made open has been described as an example, the present invention is not limited to this. For example, a dishwasher of a type in which a door is hingedly connected to an opening on the front or side surface of the washing tank so as to be tiltable, and the opening is opened by tilting the door toward the front side may be used.

[0024]

As described above, according to the dishwasher according to the present invention, since the water splash prevention member is rotatably disposed inside the washing tank, maintenance such as cleaning and inspection of the washing tank is performed. In this case, there is no need to remove the water-prevention member from the cleaning tank and place it outside, and it is not necessary to find a place where the water-prevention member is to be placed or to secure a space. In addition, since the water splash prevention member does not become dirty, it is sanitary.

[0025] A water splash prevention member is provided on a rack support member rotatably disposed inside the washing tank, and the water splash prevention member is configured to be able to rotate integrally with the rack support member. In addition, the number of components to be attached to and detached from the cleaning tank during maintenance such as cleaning and inspection of the cleaning tank can be reduced, and the work load can be reduced. In addition, it is not necessary to secure a space for placing the rack support member and the splash prevention member, and it is possible to prevent the rack support member and the splash prevention member from being soiled. In addition, since a water splash prevention member is provided on a rack support member detachably provided inside the washing tank, and the water splash prevention member can be integrally attached to and detached from the rack support member, the cleaning tank is provided. During maintenance such as cleaning and inspection, the number of components as a whole to be attached to and detached from the cleaning tank can be reduced, and the work load can be reduced. Furthermore, since the rack support member and the splash prevention member can be handled integrally, it is possible to prevent the work from being performed without removing the splash prevention member due to troublesome maintenance, and to keep the dishwasher hygienic at all times. obtain.
