DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a dishwasher for washing dishes. In particular, it relates to a type in which the cleaning tank is of a drawer type.

[0002]

2. Description of the Related Art A conventional drawer-type dishwasher (hereinafter, referred to as a dishwasher)
An example of a dishwasher will be described with reference to FIGS. FIG. 1 is a schematic longitudinal sectional view showing a state where the cleaning tank is pulled out from the main body of the cleaning machine. FIG. 2 is a schematic longitudinal sectional view showing a state in which the cleaning tank is accommodated. FIG. 3 is a cross-sectional view showing the wiper blade when the cleaning tank is at a position pulled out of the main body of the cleaning machine. FIG. 4 is a perspective view showing a state where the wiper blade is attached to the upper portion of the cleaning tank. The washing machine main body 120 has a substantially box shape and an open front surface. The cleaning tank 122 has a drawer shape with an open top, and is slidable between a position where the cleaning tank 122 is pulled out from the cleaning machine main body 120 shown in FIG. 1 and a stored position shown in FIG. The user of the dishwasher 110 is shown in FIG.
The unwashed tableware 133 is placed in the tableware basket 132 in the washing tank 122 at the drawer position, washed at the storage position shown in FIG.
Take out the washed dishes 133 from 22.

[0003] A seal plate 144 is provided so that the washing water 130 does not leak from the upper opening of the washing tank 122 during washing. The seal plate 144 is disposed at an upper position in the main body 120 of the cleaning machine. When the cleaning tank 122 is stored in the storage position, the seal plate 144 covers the upper opening of the cleaning tank 122 and moves out of the cleaning tank 122. Prevent the washing water 130 from leaking. During operation of the dishwasher 110, the washing water 130 collected at the bottom of the washing tank 122 is sucked by the washing pump 124, and the washing water 130 pressurized by the washing pump 124 is supplied to the plurality of nozzle holes 128a of the washing nozzle 128.
Spouts vigorously from Washing water 1
30 and the tableware 133 stored in the tableware basket 132
Is washed. The jetted cleaning water 130 is supplied to the cleaning tank 122.
Return to the bottom of.

The cleaning water 130 is supplied to a plurality of nozzle holes 128a.
The cleaning water 130 adheres to the lower surface of the seal plate 144 as water droplets in order to squirt vigorously. When the dishwasher 110 is performing a normal operation including a drying process, the washing water 130 attached to the lower surface of the seal plate 144 evaporates in the drying process. No water droplets remain. However, if the operation was temporarily stopped before the drying process was performed (for example, the tableware that had been forgotten to be stored was additionally stored) or the operation was performed in the operation mode in which the drying process was omitted, the operation was stopped. Even after that, water droplets remain on the lower surface of the seal plate 144.

When the cleaning tank 122 is pulled out with water droplets attached to the lower surface of the seal plate 144, the cleaning water 130 falls on the bottom of the box-shaped main body 120 of the cleaning machine. Wash water 13
If a long time elapses while 0 remains at the bottom of the main body 120, the main body 120 is corroded. Cleaning machine body 1
By manufacturing 20 from stainless steel or the like having high corrosion resistance, it is possible to suppress corrosion, but it is difficult to process and causes an increase in product cost. Further, when the cleaning tank 122 is accommodated in a state in which the cleaning water 130 is stored at the bottom of the cleaning machine main body 120, the humidity inside the cleaning machine main body 120 increases. When the humidity inside the cleaning machine body 120 increases, the cleaning machine body 12
0 (for example, the cleaning pump 124) is easily corroded.

[0006] In order to prevent the washing water 130 from dropping to the bottom of the washing machine main body 120 even when the washing tank 122 is pulled out in a state where water droplets adhere to the lower surface of the seal plate 144, the conventional dishwashing machine 110 is used. A wiper blade 145 for removing water droplets is attached along the rear upper edge of the cleaning tank 122. This is shown in detail in FIGS.
When the wiper blade 145 is provided, the cleaning tank 1
When the nozzle 22 is pulled out to the pull-out position, the wiper blade 145 wipes off water droplets adhering to the lower surface of the seal plate 144 and removes the wiped cleaning water 130 from the cleaning tank 1.
22. That is, in the conventional dishwashing machine 110, by attaching the wiper blade 145, water drops attached to the lower surface of the seal plate 144 are prevented from dropping to the bottom of the washing machine main body 120.

[0007]

However, the wiper blade 145 is worn and deformed as the cleaning tank 122 slides repeatedly. For this reason, if the conventional dishwasher 110 is used for a long period of time, the wiper blade 145 will be worn and deformed, and it will be difficult to wipe off water droplets attached to the lower surface of the seal plate 144. Since the wiper blade 145 is attached along the rear upper edge of the cleaning tank 122, even if the cleaning tank is pulled out to the drawn-out position, it is hidden below the front edge of the seal plate 144 as shown in FIG. . For this reason, it is difficult to visually check the state of wear and deformation of the wiper blade 145, or to check with a tactile sensation by inserting a hand. If it is difficult to confirm the state of wear and deformation of the wiper blade 145, the user continues to use the dishwasher 110 without noticing the malfunction of the wiper blade 145, and corrosion of the main body 120 of the washer proceeds. Further, the seal plate 144 hinders replacement of the wiper blade 145.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dishwasher in which the state of a water drop removing means such as a wiper blade can be easily checked and the replacement operation of the water drop removing means is simple.

[0009]
