Further, on the descending slope 51b of the bank portion 51, there are provided a stopper 62 for stopping and holding the cart B after rinsing and a pedal 63 for releasing the stop by the stopper 62.

The cleaning apparatus 10 of the present embodiment has the above-described configuration, and the usage method will be described next.
First, in the container washing machine 12 of the food container A arranged in the upper stage of the washing apparatus 10, the food container A is placed on the conveyor 14 and supplied to the first washing unit 15 and the second washing unit 16 in the container washing means 33. Then, washing water is jetted by the jet nozzle 19 to wash the food container A. Usually, the food container A supplied to the conveyor 14 is directed downward or sideways. In the rinsing cleaning unit 17, the rinsing water is sprayed by the spray nozzle 20 to rinse the food container A.
After the cleaning and rinsing by the container cleaning means 33 are completed, the food container A is transported to the container drying means 34, dried by spraying dry air with the drying air nozzle 29 in the drying section 18, and discharged outside.

On the other hand, in the cart cleaning machine 11, the cart transport mechanism 36 provided in the narrow space below the housing 12 a of the container cleaning means 33 is driven by the movable bar 40 to reciprocate by a predetermined distance, whereby the transport stopper 42. Thus, the carriage B is sequentially conveyed forward by a predetermined distance on the base.
When the carriage B is sequentially pushed by the conveyance stopper 42 and reaches the carriage cleaning means 37 from the carriage conveyance mechanism 36, the carriage B ascends and climbs over the ascending slope 50a in the bank 50 of the immersion tank 48, and descends the slope 50b. Then, it descends by its own weight and is immersed in the cleaning water in the immersion tank 48. In this state, the wheel 46 of the carriage B is located below the surface of the washing water. In the immersion tank 48, a large number of fine bubbles of air or nitrogen gas rise from the plurality of discharge ports 53a of the bubbling box 53, and the dirt adhering to the wheels 46 is separated and floated together with the washing action of the washing water. .

The frame 45 of the carriage B immersed in the immersion tank 48 is cleaned with cleaning water sprayed from the spray nozzle 55. Then, the carriage B is transported forward while being washed in the immersion tank 48 by the frame 45 being pushed by the conveyance arm 58 provided on the chain conveyor 57, and the carriage B which has been cleaned by the bubbling box 53 and the injection nozzle 55 is finished. Is lifted from the immersion bath 48 up the ascending slope 51 a of the bank 51.
Thereafter, rinsing water is sprayed onto the carriage B by the rinsing nozzle 60 of the carriage rinsing means 38, and dry air is further jetted from the draining nozzle 61 by the carriage drying means 39 to dry the carriage B. The carriage B descends the down slope 51 b of the bank 51 and is held in a stopped state by the stopper 62. In order to discharge the washed carriage B to the outside, the stopper 62 is released by depressing the pedal 63, and the carriage B stopped on the descending slope 51b is discharged.
Therefore, the washing of the carriage B is performed by the operator pushing the foot with the foot and pushing it into the carriage transport mechanism 36, and the washed carriage B stopped by the stopper 62 can be discharged by stepping on the pedal 63 with the foot. Can be used for cleaning.

Here, in many cases, about 10 to 20 food containers A are loaded on the carriage B and conveyed. Therefore, in the process of washing 10 to 20 food containers A with the upper container washing machine 12, one carriage B is washed with the lower

carriage washing machine

11, and 10 to 20 pieces of the carriage B after this washing are washed. It is preferable from the viewpoint of work efficiency to load and transport the washed food container A.
Moreover, since the food container A and the cart B can be cleaned separately and simultaneously in the upper and lower two-stage container cleaner 12 and the cart cleaner 11, no cross contamination occurs.

As described above, according to the cleaning apparatus 10 of the present embodiment, the lower cart washing machine 11 and the upper container washing machine 12 are stacked to form a two-stage configuration, so that the cart B and the food container are individually provided. A can be cleaned, saving space, and does not cause cross contamination.
Moreover, the food container A can be placed on the conveyor 14 around the waist and transported by an operator by hand, etc., and the cart B can be pushed into the cart transport mechanism 36 with feet or the like to be transported and washed, so that work efficiency is improved. Well, no cross contamination occurs at this point. Further, since the food container A washed by the upper container washing machine 12 can be loaded on the carriage B washed by the lower carriage washing machine 11 and discharged at the same time, the working efficiency is also very high in this respect.

In the upper container washer 12, the container cleaning means 33 for performing cleaning and rinsing is provided with the cleaning tank 23, the rinsing tank 26, the cleaning pump 24, and the rinsing pump 27. 25 is provided with a housing 12a extending further downward. For this reason, only the cleaning carriage B is transported as the carriage transport mechanism 36 in the narrow space below. In addition, a cart cleaning means 37 is installed in a relatively large space below the housing 12b of the container drying means 34. Thus, since the cart washing machine 11 is installed by effectively utilizing the small space on the lower side in the height direction of the container washing machine 12, the space saving effect is high.

Note that the cleaning apparatus 10 of the present invention is not limited to the above-described embodiment, and various modifications and replacements can be made without departing from the scope of the invention. Hereinafter, modifications and other embodiments of the present embodiment will be described, but the same or similar parts and components as those of the above-described cleaning device 10 of the first embodiment will be described using the same reference numerals.

For example, in FIG. 6, as the cleaning device of the first modified example of the cleaning device 10 of the first embodiment described above, the container cleaning unit 12 is not provided in the container cleaning machine 12, and only the container cleaning unit 33 is provided. In this case, the cart cleaning machine 11 is provided with a cart transport mechanism 36 having a small height below the casing 12a of the container cleaning means 33, and the cart cleaning means 37 that requires a large space in front of the container cleaning means 33. It can be provided so as to protrude above the transport mechanism 36.
In this case, the tableware container A after washing is naturally dried, or a separate dryer for the food container A is used.
The cleaning device 10 of such a modification is effective when the installation space is narrow and a space for installing the container drying means 34 cannot be obtained, and the cleaning device 10 with further space saving can be obtained.

Further, as a second modification of the first embodiment, for example, an existing food container A washing machine 12 in which a conveyor 14 is installed around the waist of the operator can be installed at the lower stage thereof. The cart cleaning machine 11 for step stacking will be described. The cart cleaning machine 11 of the second modification has the same configuration as that of the above-described embodiment, and the cart transport mechanism 36 having a small height and the cart cleaning means 37 having a height higher than the cart transport mechanism 36 are provided. Are continuously arranged.

Moreover, the existing container cleaning machine 12 includes the first cleaning unit 15, the second cleaning unit 16, and the rinsing cleaning unit 17 in the container cleaning means 33, and the cleaning tank 23, the rinsing tank 26, Since it has the housing | casing 12a which each arrange | positioned the washing | cleaning pump 24 and the rinse pump 27, it occupies the volume protruded below rather than the housing | casing 12b of the drying part 18 which does not have a tank and a pump.
Therefore, in the cart cleaning machine 11 of the second modified example, the cart transport mechanism 36 having a small height is installed below the container cleaning device 33, and the cart cleaning device 37 having a large height below the container drying device 34. The space-saving two-stage laminating type cleaning apparatus 10 can be obtained.

By the way, in the cart washing machine 11 of the washing apparatus 10 of the present embodiment, dust and dirt, and further oil such as fats and oils adhere to the wheels 46 of the cart B. Therefore, it is preferable to use hot water of about 50 ° C. to 80 ° C., for example. The wheels 46 of the carriage B are washed by causing fine bubbles of air or nitrogen gas to float from the outlet 53a of the bubbling box 53 to the washing water in the immersion tank 48.

However, in this case, the steam of the hot water floats upward and flows forward and flows to the exit of the carriage B after the completion of washing. However, the carriage drying means 39 is provided in the vicinity of the exit, and the draining nozzle 61 that ejects dry air is used. In order to dry the carriage B, the steam is driven to the rear entrance 37a in the carriage washing means 37, that is, the vicinity of the exit of the carriage transport mechanism 36, due to the blowing of dry air. Then, there is a problem that the vicinity of this structure is an open structure, so that steam is scattered outside through the gap between the carriage cleaning means 37 and fills the room.
The cart washing machine 11 of the washing apparatus 10 in the second embodiment can improve such a problem.

FIG. 7 shows a configuration of a main part of the cart washing machine 11 of the washing apparatus 10 according to the second embodiment of the present invention.
In the second embodiment, hot water of about 50 ° C. to 80 ° C. is used as the cleaning water stored in the immersion tank 48. An intermediate cover 65 for recovering vapor evaporated from the cleaning water in the immersion tank 48 is disposed above the immersion tank 48. The intermediate cover 65 is exhausted from the intermediate exhaust port 66 through the exhaust duct 67. A fan 68 is connected. The steam collected by the exhaust fan 68 is discharged outdoors or collected and used for other purposes.

Further, the entrance 37 a of the carriage B on the rear side of the carriage cleaning means 37 is an area where the carriage B is discharged from the exit of the carriage transport mechanism 36. In the vicinity of the entrance 37a of the carriage B, for example, a rising slope 50a of the bank 50 is disposed, and a base cover 70 for steam recovery is disposed above the slope 50a. A base exhaust port 71 connected to the base cover 70 is connected to an exhaust duct 67 via a base exhaust duct 72. The base cover 70 for collecting the steam is installed in the region of the ascending slope 50a of the bank portion 50, but may extend to the descending slope 50b. The base exhaust port 71 provided with the base cover 70, the base exhaust duct 72, and the exhaust fan 68 constitute a first exhaust means, and the intermediate exhaust port 66 provided with the intermediate cover 65, the exhaust duct 67, and the exhaust fan 68 include A second exhaust means is configured.

Therefore, according to the cart cleaning machine 11 of the cleaning apparatus 10 of the second embodiment, in the state where the cart B is not cleaned, the cleaning water stored in the immersion bath 48 is discharged from the discharge port 53a of the bubbling box 53. In combination with air bubbles or fine bubbles of nitrogen gas that rise, the vapor rises into the air, and the vapor is collected through the intermediate cover 65 and absorbed, and is collected by the exhaust fan 68 through the intermediate exhaust port 66 and the exhaust duct 67.

Further, in the cleaning state of the carriage B, the carriage B is washed by the carriage washing means 37 and then conveyed to the carriage drying means 39, and the carriage B is quickly dried by air injection from the draining nozzle 61. At that time, the steam that floats in the air together with bubbles from the surface of the washing water stored in the immersion tank 48 flows in the direction of the exit of the carriage drying means 39. Is returned to the vicinity of the entrance 37a of the carriage cleaning means 37. Thereafter, the air is sucked into the base cover 70 in the vicinity of the inlet 37 a of the carriage cleaning means 37 and is collected by the exhaust fan 68 through the base exhaust port 71 and the base exhaust duct 72.

As described above, according to the cleaning device 10 of the second embodiment, even if hot water is used as cleaning water, the steam that floats from the immersion tank 48 and flows in the outlet direction is discharged from the drain nozzle 61 of the cart cleaning machine 11. Since it is blown off and sent to the vicinity of the inlet 37a of the carriage cleaning means 37 and quickly recovered through the base cover 70 and the base exhaust port 71, it is possible to prevent the interior from being filled with steam and causing inconvenience to work.

Next, the cleaning apparatus 10 of the third embodiment will be described with reference to FIG.
In the cart cleaning machine 11 of the cleaning apparatus 10 of the third embodiment, a cylindrical exhaust cover 75 that covers at least the entire cart cleaning means 37 is disposed as a means for collecting steam, instead of the intermediate cover 65 and the base cover 70. Has been established. The exhaust cover 75 preferably covers from the entrance 37a of the carriage cleaning means 37 to the carriage drying means 39, and the entrance 37a and the outlet 75a are openings through which the carriage B passes. An intermediate exhaust port 66 and a base exhaust port 71 are connected to the exhaust cover 75, and sucks steam that floats in the immersion tank 48 of the cart cleaning means 37, steam blown off to the inlet 37a side by the draining nozzle 61, and the like. Then, the exhaust fan 68 collects it.

It should be noted that the exhaust cover 75 may be configured to cover only the side surface because the carriage cleaning means 37 is provided with a ceiling or floor surface, or may be configured to cover the ceiling or floor surface. Further, only one of the intermediate exhaust port 66 and the base exhaust port 71 may be provided as the exhaust port.

According to the cart washing machine 11 of the third embodiment, it is possible to reliably suck and collect steam over a wider range than the intermediate cover 65 and the base cover 70 in the second embodiment.

In the cart washing machine 11 of the washing apparatus 10 in each of the above-described embodiments and modifications thereof, the immersion tank 48 provided in the cart washing means 37 is installed on the base, and the surroundings are the

dams

50 and 51 and the wall surface 49. However, instead of this configuration, a dimple is dug down below the base to form a recess, and a down slope and an up slope are formed at its front and back positions. The dipping tank 48 may be formed by filling a cleaning liquid.
If such a configuration is adopted, the height of the carriage cleaning means 37 can be set smaller, so that there is a margin in the space.
