Therefore, if the washing water of the immersion tank 48 is simple water, it is difficult to Since it is washed off, it is preferable to use hot water of, for example, about 50 ° C to 80 ° C. Then, in the washing water in the dipping tank 48, the wheel 46 of the bogie B is cleaned by floating fine bubbles of air or nitrogen from the discharge port 53a of the bubbler box 53.

However, in this case, the steam of the hot water floats upward and flows forward. The steam flows into the outlet of the trolley B after the completion of the cleaning. However, since the trolley drying unit 39 is provided in the vicinity of the outlet, and the trolley B is dried by the dehydrating nozzle 61 that discharges the dry air, the steam is caused by the discharge of the dry air. The entrance 37a on the rear side in the trolley washing unit 37, that is, the vicinity of the exit of the carriage conveying mechanism 36 is reached. Therefore, since the vicinity is an open structure, there is a problem that steam is scattered from the gap of the trolley washing unit 37 to the outside to fill the room.

The trolley washing machine 11 of the cleaning device 10 of the second embodiment can also improve such a problem.

Fig. 7 is a diagram showing the main components of the washing machine 11 of the washing apparatus 10 according to the second embodiment of the present invention.

In the second embodiment, the washing water stored in the immersion tank 48 is made of hot water of about 50 ° C to 80 ° C. Further, an intermediate cover 65 for recovering the vapor evaporated from the washing water in the dipping tank 48 is disposed in the upper portion of the dipping tank 48, and the intermediate cover 65 is passed from the intermediate exhaust port 66 via the intermediate exhaust port 66. The exhaust duct 67 is coupled to the exhaust fan 68. The steam recovered by the exhaust fan 68 will be discharged to the outside of the house or recycled for other uses.

Further, the inlet 37a of the carriage B on the rear side of the trolley washing unit 37 is an area where the carriage B is discharged from the exit of the carriage conveying mechanism 36. For example, a rising slope 50a of the bank 50 is disposed in the vicinity of the inlet 37a of the carriage B, and a base cover 70 for steam recovery is disposed above the rising slope 50a. The base exhaust port 71 coupled to the base cover 70 is connected to the exhaust duct 67 via a base exhaust duct 72. Further, the base cover 70 for recovering steam is provided in the region of the rising slope 50a of the bank 50, but may extend to the descending slope 50b. Further, the base exhaust port 71 provided with the base cover 70, the base exhaust duct 72, and the exhaust fan 68 constitute the first The exhaust unit, the intermediate exhaust port 66 provided with the intermediate cover 65, the exhaust duct 67, and the exhaust fan 68 constitute a second exhaust unit.

Therefore, the trolley washing machine 11 of the cleaning device 10 according to the second embodiment floats with the discharge port 53a of the self-foaming box 53 in the washing water stored in the immersion tank 48 in a state where the carriage B is not cleaned. The fine air bubbles of air or nitrogen combine to raise the steam into the air, and the steam is concentratedly absorbed by the intermediate cover 65, and is recovered by the exhaust fan 68 through the intermediate exhaust port 66 and the exhaust duct 67.

Then, in the washing state of the carriage B, the carriage B is washed by the trolley washing unit 37, then conveyed to the trolley drying unit 39, and the trolley B is quickly dried by the air injection from the dewatering nozzle 61. At this time, the steam floating in the air from the liquid surface of the washing water stored in the dipping tank 48 and the air bubbles flows toward the outlet direction of the trolley drying unit 39, but the steam is blown by the dewatering nozzle 61 along the trolley washing unit 37. The top of the head is returned to the vicinity of the inlet 37a of the trolley washing unit 37. Thereafter, the steam is sucked into the base cover 70 in the vicinity of the inlet 37a of the trolley washing unit 37, and is recovered by the exhaust fan 68 through the base exhaust port 71 and the base exhaust duct 72.

According to the cleaning apparatus 10 of the second embodiment as described above, even if hot water is used as the washing water, the steam that has floated from the immersion tank 48 to the air and flows toward the outlet direction is blown off by the dehydration nozzle 61 of the trolley washing machine 11. Further, it is sent to the vicinity of the inlet 37a of the trolley washing unit 37, and is quickly recovered by the base cover 70 and the base exhaust port 71. Therefore, it is possible to prevent the interior of the trolley from being filled with steam and causing inconvenience to the work.

Next, the cleaning device 10 of the third embodiment will be described with reference to Fig. 8 .

In the trolley washing machine 11 of the cleaning device 10 of the third embodiment, Instead of the intermediate cover 65 and the base cover 70, the unit for recovering steam is provided with a cylindrical exhaust cover 75 that covers at least the entire of the trolley cleaning unit 37. The exhaust hood 75 is preferably covered from the inlet 37a of the trolley washing unit 37 to the trolley drying unit 39, and the inlet 37a and the outlet 75a are provided as openings through which the carriage B passes. Further, the intermediate exhaust port 66 and the base exhaust port 71 are connected to the exhaust hood 75, and the steam floating in the immersion tank 48 of the carriage washing unit 37 or the steam blown to the inlet 37a side by the dehydration nozzle 61 is performed. The suction is recovered by the exhaust fan 68.

Further, since the exhaust cover 75 is provided with a top portion and a bottom surface in the trolley cleaning unit 37, it may be configured to cover only the side surface or to cover the top or bottom surface. Further, only one of the intermediate exhaust port 66 and the base exhaust port 71 may be provided as an exhaust port.

According to the trolley washing machine 11 of the third embodiment, the steam can be reliably sucked and collected over a wider range than the intermediate cover 65 and the base cover 70 of the second embodiment.

Further, in the cart washing machine 11 of the washing apparatus 10 according to each of the above-described embodiments or its modifications, the dipping tank 48 provided in the cart washing unit 37 is provided on the base, and the bank 50, the bank 51, and the wall surface are provided. 49 is surrounded by the periphery, and the cleaning liquid is filled in the inside of the dipping tank 48. However, instead of this configuration, the recess may be excavated below the base to form a recessed portion, and a descending slope and a rising bevel may be formed at the front and rear positions of the recess. The inside of the recess is filled with the cleaning liquid to form the immersion tank 48.

According to this configuration, the height of the trolley washing unit 37 can be set smaller, so that a margin is generated in the space.
