BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described along with examples with reference to the drawings. FIG. 1 is an operation explanatory view showing one embodiment of the dishwashing apparatus 1, FIG. 2 is an explanatory plan view thereof, and FIG. 3 is a side view thereof. As shown in FIG. 2, the dishwashing apparatus 1 includes a conveyor-type washing machine 2, a first stocker 3 for storing dishes, a second stocker 4, and a transport device 5. In the embodiment, the stockers 3 and 4 include two stockers, a stocker 3 for a regular bowl and a stocker 4 for a large bowl or a special bowl, but the present invention is not limited to this.
[0010]
As shown in FIG. 1, the conveyor-type washing machine 2 has a washing unit 6 for washing tableware mainly by injecting high-pressure water from below, and carries in the tableware with a circulating conveyor 7 passing through the washing unit 6. It is sent from the port 8 to the exit 9. The circulating conveyor 7 is rotated and circulated by a drive motor 10. In addition, since the washing unit 6 in the present invention is for cleaning dishes by mainly spraying high-pressure water from below, the tableware is brought into the carry-in port 8 in a face-down state (with the tableware such as the bowl 13 lying down). That is, with the main cleaning surface facing downward). In addition, as shown in FIG. 4, the carry-in entrance 8 of the conveyor-type washing machine 2 is installed on the hall side, and the stockers 3 and 4 are installed on the cooking place side.
[0011]
The circulating conveyor 7 of the conveyor-type cleaning device 1 is separated into a bowl cleaning line 11 serving as a deep-bottom tableware cleaning line and various tableware cleaning lines 12. The line on the right in FIG. 1 is a bowl washing line 11, and the line on the left is various dish washing lines 12 mainly for washing shallow dishes and the like. The bowl 13 washed in the bowl washing line 11 includes a special bowl, a large bowl, and a regular bowl, and the dishes washed in the dishwashing line 12 include dishes, small bowls, and a half for storing them. Also includes the rack 19 and the like.
[0012]
The bowl washing line 11 is provided with a washing section 6, a bowl holding device 27, and an air jet nozzle 26 as a drainer downstream of the washing section 6.
[0013]
The cleaning unit 6 includes a main cleaning nozzle 23 that is connected to the high-pressure water generating pump 22 and injects high-pressure water, and a rinse nozzle 24 that is provided downstream of the main cleaning nozzle 23. Since the washing unit 6 is mainly for washing tableware by injecting high-pressure water from below, the main washing nozzles 23 are arranged upward from below the circulating conveyor 7 in the embodiment. 7 are installed from above to below.
[0014]
In the embodiment, the number of the rinsing nozzles 24 is one for each of the upper and lower sides. Therefore, the circulating conveyor 7 has a structure through which the jet water from the main cleaning nozzle 23 and the rinsing nozzle 24 can pass, but the circulating conveyor 7 is not different from the conventional products.
[0015]
Further, a bowl holding device 27 for preventing the bowl 13 from being blown by the high-pressure water is provided above the circulation type conveyor 7 from which the high-pressure water is jetted from the main cleaning nozzle 23. An air injection nozzle 26 connected to an air blow 25 is provided downstream of the washing unit 6 to blow off water remaining on the bottom of the bowl 13.
[0016]
In the various dish washing lines 12, only the washing section 6 and the dish holding device 28 are provided. These components are the same as those of the bowl washing line 11. However, the air jet nozzle 26 is unnecessary and is not provided in the various dish washing lines 12, and the structure of the dish holding device 28 is different from that of the bowl holding device 27.
[0017]
Immediately after the outlet 9 of the conveyor-type washing machine 2, there is a separation chute 14. The bowl 13 unloaded from the bowl washing line 11 and the conveyer other than the bowl 13 are removed by the separation chute 14, and the bowl 13 is transported by the transport conveyor 15. The transport conveyor 15 is mounted at an angle, and transports the bowl 13 to one side of the transport conveyor 15.
[0018]
A separation conveyor 16 is installed downstream of the conveyor 15 and is sorted according to size. Only the small row of rice bowls is dropped on the first transfer conveyor 17 and stacked on the first stocker 3. The large bowl 13 does not fall on the separation conveyor 16, but is stacked on the second stocker 4 by the second transfer conveyor 18. The first stocker 3 and the second stocker 4 are provided with a lifter that pushes up the bowl 13 with the bowl 13 lying down and a turntable that stacks the bowl 13.
[0019]
The half rack 19 and tableware carried out from the various dishwashing line 12 are dropped from the separation chute 34 into the tableware basket 20 for the small tableware, and the half rack 19 not sorted by the separation chute 34 is separated by the rack stock conveyor 21. It is stored in a separate storage device (not shown).
[0020]
【The invention's effect】
The present invention has a washing section for washing dishes by mainly spraying high-pressure water from below, and a conveyor-type washing machine for sending dishes from a carry-in port to a carry-out port by a circulating conveyor passing through the washing section; Dishwasher having a plurality of stockers for storing tableware and a transport device for transporting dishes to the stocker from a carry-out port of the conveyor-type washing machine, the circulation-type conveyor of the conveyor-type washing device uses a deep-bottom dishwashing line and various types of dishwashing. Separated from the line, the deep dishwashing line was equipped with a drainer that sprays gas downstream of the washing section, and the dishwasher was installed above the washing section in the deep dishwashing line and various dishwashing lines. The dishwasher was characterized by the following features: it can be used for a wide variety of tableware, and can be automatically processed at the time of unloading without manual intervention.
[0021]
According to the effect of the second aspect of the present invention, an arbitrary number of stockers out of the plurality of stockers are used for storing deep-dish dishes, and a lifter and a deep-dish dish are pushed up in a state where the deep-dish dishes are laid down on the stockers. With a turntable, there is no need to manually stack washed deep-bottom dishes.
[0022]
Although it is an effect of the invention according to claim 3, since the carry-in entrance of the conveyor-type washing machine is installed on the hall side and a plurality of stockers are installed on the cooking site side, no manual work is required, Used tableware brought in from the hall can be washed and stored in the kitchen. This is also very hygienic at the same time.
