Is inserted through. The filter 52 functions to prevent a large foreign matter or the like that has fallen on the receiving portion 34 from entering the connecting pipe 38 and clogging.
[0010]
[Effect of the embodiment]
Next, the operation of the dishwasher according to the embodiment will be described below. When the top plate 32 of the tableware washing machine 22 is used as a work table, an empty tableware rack 30 is placed on the receiving portion 34 of the top plate 32 (see FIG. 2). Then, the tableware pre-processed by the soil table (see FIG. 5) is set in the tableware rack 30. In this case, the residue adhering to the tableware and the sewage such as the washing water attached when prewashed are received by the receiving portion 34 and dropped onto the installation floor surface along the outer wall surface of the main body. And can prevent the floor from getting wet. In addition, since sewage does not flow on the side and rear of the washing machine main body 24, which is difficult to clean due to walls and other kitchen equipment, the surface and installation floor are not contaminated, and it is hygienic without frequent cleaning. Can be kept in.
[0011]
The sewage received by the receiving portion 34 flows into the hose 40 from the drain port 36 through the connection pipe 38 and is discharged to the outside through the collective drainage portion 42, the main body drain port 44 and the drain pipe 46. . That is, even if a large amount of sewage falls from the tableware to the receiving unit 34, the sewage can be discharged quickly, so that a large amount of sewage does not accumulate in the receiving unit 34 and overflow, It is not necessary to wipe off the dirty water in 34. Thereby, an operator's burden can be reduced.
[0012]
Further, in the case where the top plate 32 of the dishwasher 22 is used as a table for the tableware after washing, if the tableware is placed in the receiving portion 34, water drops dripping from the tableware can be received by the receiving portion 34. Further, wetting the outer wall surface of the main body and the installation floor surface with the water droplets is prevented. And this water droplet is discharged | emitted out of the machine from the said drain outlet 36, and does not accumulate in the receiving part 34 for a long time.
[0013]
A filter 52 is disposed at the drain port 36 of the receiving portion 34, and the filter 52 prevents large foreign matter from entering the connection pipe 38, so that the connection pipe 38 is prevented from being clogged by foreign matter. Can do. Even if sludge-like foreign matter accumulates in the connection pipe 38, it can be easily washed away with tap water or the like by removing the filter 52. Further, since the filter 52 prevents large foreign matter from clogging the connection pipe 38, the pipe diameter of the connection pipe 38 and the hose 40 can be increased, and a sufficient drainage flow rate can be secured.
[0014]
Here, for example, when foreign matter enters the connection pipe 38 due to forgetting to attach the filter 52 or the like, it may be removed by sticking with a bar 54 such as a ladder as shown in FIG. In this case, since the connection pipe 38 is formed in a substantially L shape, even when the bar 54 hits the connection pipe 38 when removing foreign matter, it hits the rubber or synthetic resin hose 40. There is nothing. That is, the rod 54 does not hit the hose 40 connected to the connection pipe 38 and no force is applied, and the hose 40 can be prevented from being damaged or coming out of the connection pipe 38 in advance. Thereby, it can prevent that water leaks from the connection part of the hose 40 and the connection pipe 38, or the hose itself.
[0015]
【The invention's effect】
As described above, according to the dishwasher according to the present invention, when the top plate is used as a work table or a table, sewage or the like that falls from the table is main body. It can prevent dripping on an installation floor surface along an outer wall surface. That is, the outer wall surface and the installation floor surface of the cleaning machine main body can be prevented from getting wet or dirty, and can be kept hygienic. Further, since the sewage received by the receiving part is quickly discharged through the drain port, there is no need to frequently wipe off the sewage and the like, and the burden on the operator can be reduced. In addition, since a hose for discharging sewage discharged from the drainage port to the outside of the machine is connected to the drainage port via a connection pipe formed in an approximately L shape, foreign substances clogged in the connection pipe are removed. Even in the case of removing by striking with a bar material such as a shim, it is possible to prevent the bar material from directly hitting the hose and damaging the hose or coming out of the connecting pipe. Thereby, it can prevent that water leaks from the connection part of a hose and a connection pipe, or the hose itself.
