FIG. 5 is a perspective view showing a state where the wiper blade is attached to the cleaning tank. FIG. 6 is a sectional view taken along the line VI-VI of FIG. 2 and shows a floor on which a washing tank and a dishwasher are installed. In FIG. 6, illustration of the tableware basket is omitted. As shown in FIG. 1 to FIG.
Reference numeral 20 denotes a substantially box-like shape, and its front surface (the left side in FIGS. 2 and 3; the right side in the drawings is the rear side) is open. The cleaning tank 122 has a drawer shape whose upper part is open, and is slidable between a position shown in FIG. 2 pulled out from the main body 120 of the cleaning machine 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, and the washing tank 122 is placed in the storage position shown in FIG. 3, and the dishwasher 110 is operated to wash the tableware 133. After the operation of the dishwasher 110, the washing tank 122
Is pulled out to the drawer position, and the washed tableware 133 is taken out of the washing tank 122.

[0003] A seal plate 144 is provided so that the washing water 130 does not leak from the washing tank 122 during washing. The seal plate 144 is disposed above the main body 120 of the cleaning machine. When the cleaning tank 122 is stored in the storage position, the seal plate 144 is lowered. When the seal plate 144 descends, the seal 144a attached to the peripheral edge of the lower surface of the seal plate 144 becomes the upper edge 1 of the cleaning tank.
The cleaning water 13 is pressed against the cleaning tank 122
Cover so that 0 does not leak. During the operation of the dishwasher 110, the washing water 130 accumulated at the bottom of the washing tank 122 is sucked by the washing pump 124, and
The cleaning water 130 pressurized in step 4 gushes out from the plurality of nozzle holes 128a of the cleaning nozzle 128. The tableware 133 stored in the tableware basket 132 is washed by the washing water 130 that spouts vigorously. Blow out tableware 133
Is returned to the bottom of the cleaning tank 122.

The cleaning water 130 is supplied to a plurality of nozzle holes 128a.
The cleaning water 130 is applied to the lower surface of the seal plate 144 and the upper edge 122a of the cleaning tank so that the water droplets 13
It adheres as 0a. When the dishwasher 110 is performing a normal operation including a drying process, the cleaning water 130 attached to the lower surface of the seal plate 144 and the upper edge 122a of the cleaning tank evaporates in the drying process, and thus after the operation is stopped. No water droplet 130a remains. However, when the operation is temporarily stopped before the drying step is performed, or when the operation is performed in the operation mode in which the drying step is omitted, the water droplets 130a of the cleaning water 130 remain on the lower surface of the seal plate 144 even after the operation is stopped.
Is attached. Further, the water droplets 130 are also placed inside the seal 144a of the seal plate 144 on the upper edge 122a of the cleaning tank.
a is attached.

[0005] As shown in FIG. 2, when the cleaning tank 122 is pulled out with the water drops 130 a adhered to the lower surface of the seal plate 144, the cleaning water 130 falls to the bottom of the main body 120 of the cleaning machine. When a long time elapses while the washing water 130 remains at the bottom of the washing machine body 120, the washing machine body 1
Causes 20 corrosion. Corrosion can be suppressed by manufacturing the main body 120 of the washing machine with stainless steel having high corrosion resistance, but this increases the product cost. When the washing tank 122 is accommodated in a state where the washing water 130 is stored at the bottom of the washing machine main body 120, the humidity inside the washing machine main body 120 increases. When the humidity inside the cleaning machine main body 120 becomes high, the components inside the cleaning machine main body 120 (for example, the cleaning pump 124) are corroded. When the cleaning tank 122 is pulled out with the water droplets 130a attached to the upper edge 122a of the cleaning tank, the water droplets 130a are
0 and the floor 171 where the dishwasher 110 is installed
To fall.

[0006] Water droplets 130 are formed on the lower surface of the seal plate 144.
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 in which the a
A wiper blade 145 is attached along a rear upper edge of the rear end 22 (for example, JP-A-2000-166850). This is shown in detail in FIGS. When the wiper blade 145 is provided, the wiper blade 14
5 is a water droplet 130 attached to the lower surface of the seal plate 144
a is wiped and returned into the cleaning tank 122. That is, in the conventional dishwasher 110, by attaching the wiper blade 145 along the rear upper edge of the washing tank 122, it is possible to prevent the water droplets 130 a attached to the lower surface of the seal plate 144 from falling to the bottom of the main body 120 of the washing machine. Had been prevented. Also,
In the above publication, a water detection sensor 157 is provided at the bottom of the main body 120 of the washing machine, and the water droplets 130 a
There is described a technique for detecting that the camera has dropped.

[0007]

However, the wiper blade 145 is deteriorated (wear, deformation, crack, etc.) by repeated sliding of the cleaning tank 122. For this reason, if the conventional dishwasher 110 is continuously used, the wiper blade 145 deteriorates and the sheet plate 144 is deteriorated.
The water droplets 130a of the cleaning water 130 attached to the lower surface cannot be wiped well. When the wiper blade 145 deteriorates and the water droplet 130a attached to the lower surface of the seal plate 144 cannot be wiped, the cleaning tank 122 is pulled out.
The washing water 130 falls on the bottom of the washing machine main body 120. Since the wiper blade 145 is attached along the rear upper edge of the cleaning tank 122, as shown in FIG. Hiding. For this reason, the state of deterioration of the wiper blade 145 is visually recognized, or
It is difficult to put in your hand and check with the tactile sensation. If it is difficult to confirm the state of deterioration of the wiper blade 145, the user continues to use the dishwasher 110, and the washing water 130 continues to fall on the bottom of the main body 120 of the washer. When the washing water 130 is left at the bottom of the washing machine main body 120,
Corrosion of the cleaning machine main body 120 proceeds.

The seal 14 of the seal plate 144
4a may be deteriorated (wear, deformation, cracking, etc.) or the connection between the cleaning pump 124 and the cleaning water passage may be damaged, so that the cleaning water 130 may leak out. Hereinafter, it is referred to as leakage water). Leaked water is the main body of the washing machine 12
If it falls to the bottom of 0, corrosion of the cleaning machine main body 120 will progress.

As shown in FIG. 6, when the cleaning tank 122 is pulled out of the housing position with the water droplets 130a of the cleaning water 130 adhered to the upper edge 122a of the cleaning tank, the water droplets 130a are shaken off by this movement. Water drops 13 shaken off
0a is the cleaning machine main body 120 and the drawn out cleaning tank 12
Floor 171 where the dishwasher 110 below 2 is installed
To fall. The water droplets 130 a of the cleaning water 130 that has fallen to the bottom of the main body 120 cause corrosion of the main body 120. The water droplets 130a that have fallen on the floor 171 are particularly conspicuous as dirt when the cleaning tank 122 is returned to the storage position, and give the user discomfort. Also, the cleaning machine body 120
Even if the water detection sensor is provided at the bottom of the cleaning tank 122, if the cleaning water 130 leaks from the cleaning tank 122 in a state where the cleaning tank 122 is pulled out to the draw-out position, it cannot be detected.

According to the present invention, the cleaning water is supplied to the main body of the cleaning machine, and / or
Another object is to provide a dishwasher capable of preventing the dishwasher from dropping on a floor on which the dishwasher is installed.

And a washing tank water receiving pan. According to the dishwasher according to the present invention, the leaked water does not fall to the bottom of the main body of the washing machine, but is received by the washing tank water receiving pan. For this reason, water does not fall on the main body of the washing machine, so that corrosion of the main body of the washing machine does not occur. Further, according to the dishwasher according to the present invention, when the washing tank is pulled out, water drops of washing water falling from the upper edge of the washing tank are received by the washing tank water receiving pan. Therefore, the water drops do not fall on the floor on which the main body of the washing machine and the dishwasher are installed. Therefore, according to the configuration of the present invention, it is possible to prevent the washing water from dropping on the floor where the washing machine main body and the dishwasher are installed.

[0013] In the dishwasher according to the second aspect, it is preferable that a water detection sensor for detecting water is attached to the washing tank water pan. ADVANTAGE OF THE INVENTION According to the dishwasher which concerns on this invention, the leaking water and the water droplet of the washing water which falls from the upper edge of a washing tank when a washing tank is pulled out are received by a washing tank water receiving pan. The washing water received by the washing tank water receiving pan is detected by the water sensor before overflowing from the washing tank water receiving pan. Therefore, the washing water does not overflow from the washing tank water receiving pan and drop onto the floor on which the dishwasher body and the dishwasher are installed. Therefore, according to the configuration of the present invention, it is possible to prevent the washing water from dropping on the floor where the main body of the washing machine and the dishwasher are installed. Also, unlike a conventional dishwasher in which a water detection sensor is attached to the main body of the washing machine (Japanese Patent Laid-Open No. 2000-166850), the water detection sensor of the present invention is provided with a washing water receiving pan. Therefore, even if the washing water leaks from the washing tank when the washing tank is pulled out to the draw-out position, it can be detected.
