Alternatively, it may be bent in a U-shape facing toward the bottom or a Z-shape in which the tip portions of the bottom portions 43 and 51 face downward.

  As shown in FIGS. 2 and 3, the water storage chamber 6 is provided with a tank 7 that receives the cleaning water W used in the cleaning chamber 2. The tank 7 is a tank for storing the cleaning water W and circulating it to the cleaning chamber 2. The tank 7 is connected from the suction port 71 to the pump 61, and is cleaned from the discharge port 62 of the pump 61 through the cleaning water pipe 31. Each of the nozzles 33 and 34 provided in the chamber 2 is connected to each other. Further, the tank 7 is provided with a water pipe 32 connected to the water through a water valve (not shown). When this water supply valve is opened, water is supplied from the water supply pipe 32 to the tank 7.

  Furthermore, a heater 63 for heating the cleaning water W is provided in the tank 7, and a strainer 64 that removes the residue that has flowed down from the tableware D is provided between the transport conveyor 27 and the tank 7. A water return 72 is provided on the inner wall of the tank 7 to prevent the water surface of the cleaning water W in the tank 7 from undulating due to the steam blown from the heater 63 and getting over the tank 7.

  Further, an overflow receiving portion 73 as one configuration of the tank 7 is provided at one end or both ends of the tank 7 in the front-rear direction. When the washing water W stored in the tank 7 exceeds a predetermined amount, the overflow receiving portion 73 gets over the partition plate 74 provided between the overflow receiving portion 73 and flows into the overflow receiving portion 73 to be drained. To 75. Thereby, the washing water W stored in the tank 7 can be maintained at a predetermined amount.

  In addition, when the detergent cleaning unit 21 is further divided into the rough cleaning unit 22 and the main cleaning unit 23, tanks 7a and 7b corresponding to the rough cleaning unit 22 and the main cleaning unit 23 are provided, respectively. The tank 7a of the rough cleaning section 22 is connected to the pump 61a from the suction port 71a, and has a plurality of upper nozzles 33a and lower ports provided in the cleaning chamber 2 from the discharge port 62a of the pump 61a through the cleaning water pipe 31a. It is connected to the side nozzle 34a. Further, the tank 7 b of the main cleaning unit 23 is also connected to a plurality of upper nozzles 33 b and lower nozzles 34 b as with the rough cleaning unit 22.

  In this case, the downstream tank 7b is provided across the main cleaning section 23 and the rinsing cleaning section 24 of the cleaning chamber 2, and from the upper nozzle 33b and the lower nozzle 34b of the main cleaning section 23 disposed on the downstream side. The sprayed wash water W and the clean water sprayed from the upper nozzle 35 and the lower nozzle 36 connected to the clean water pipe 32c can be received.

  In the case where an overflow receiving part 73b ′ is provided between the tank 7a of the rough cleaning part 22 and the tank 7b of the main cleaning part 23, for example, the cleaning water W used in the main cleaning part 23 is relatively less contaminated. In order to reuse the mixed water of the clean water used in the rinsing washing section 24, the drain pipe 75b 'of the overflow receiving section 73b' is closed by a valve and is moved upstream from the main washing tank 7b provided on the downstream side. If it does not need to be reused, the valve may be opened and discharged to the drain pipe 75b 'as it is.

  At the upper ends of these tanks 7a and 7b, a flange 8 formed by bending is formed. As shown in FIGS. 2 and 3, the flange 8 is provided at the edge of the upper opening of the tanks 7a and 7b on which the upper cover 4 and the door 5 are placed, and extends upward from the bottom of the tanks 7a and 7b. The horizontal mounting portion 81 is formed by bending the extended inner wall outward, and a rising portion 82 that is bent upward from the tip of the mounting portion 81 and covers the upper cover 4 and the vicinity of the lower portion of the door 5.

  The flange portion 8 provided in the tank 7 forms a rectangular shape in top view so as to surround the periphery of the cleaning device 1. When a plurality of tanks 7 are used as shown in FIG. 4 (a), when the cleaning device 1 is formed by connecting a plurality of tanks 7a and 7b, similarly, the flange 8 that continuously surrounds the periphery of the cleaning device 1 is used. All the mounting portions 81 are formed with a horizontal surface having no step as a whole, and all the rising portions 82 extend upward at the same height on the rectangular outer ring in the top view of the cleaning device 1. When a plurality of tanks 7a and 7b are connected, a partition plate 74 is provided at an edge portion of each tank 7a and 7b that is not located around the cleaning device 1, that is, a joint surface between the tank 7a and the tank 7b.

  In addition, the flange portion 8 is provided with a leak-proof plate 9 that is disposed so as to cover the rising portion 82 from above and is formed by bending an elongated flat plate into a J-shape in cross-sectional view. The short side piece 91 of the leak-proof plate 9 is in contact with the inside of the rising portion 82, and the tip thereof is located up to the placement portion 81. The long side piece 92 of the leak-proof plate 9 is in contact with the outside of the rising portion 82, the tip thereof is located below the mounting portion 81, and the long side piece 92 of the leak-proof plate 9 is the water storage chamber 6. It covers so as to support the upper part of the decorative board 65 attached to.

  As shown in FIG. 4B, when a plurality of tanks 7a and 7b are connected, a slight gap is formed between the rising portions 82 of both adjacent tanks 7a and 7b. A rectangular shape in a top view is formed so as to cover the gap and surround the cleaning device 1 without interruption. That is, the leak-proof plate 9 covers all of the plurality of rising portions 82.

  Next, the operation and effect of the cleaning apparatus 1 according to the present invention will be described.

  After opening the water supply valve and supplying the water to the tanks 7a and 7b via the water supply pipes 32a and 32b to fill the tank, the water supply valve is closed and the heaters 63a and 63b are operated to operate the tank 7a. 7b water is heated to a predetermined temperature. A detergent is put into the tank 7 a according to the type of tableware D and the degree of dirt, and the door 5 is attached to the door openings 41 on the left and right side surfaces of the upper cover 4.

  The conveyor 27 and the pumps 61a and 61b are driven, the water supply valve of the rinse cleaning unit 24 is also opened, and the operation of the cleaning device 1 is started. The cleaning water W sucked by the pump 61a connected to the tank 7a passes through the cleaning water pipe 31a to the upper nozzle 33a and the lower nozzle 34a of the rough cleaning section 22, and is sucked by the pump 61b connected to the tank 7b. The washing water W is pumped to the upper nozzle 33b and the lower nozzle 34b of the main washing section 23 through the washing water pipe 31b, respectively, and is pressed from the carry conveyor 27 to the carry-out port 26 while being pressed by the hold conveyor 28. It sprays from the up-down direction toward the flowing tableware D. During cleaning, when the cleaning water W in the tanks 7a and 7b becomes lower than a predetermined water level, the water supply valve is opened and water is appropriately supplied via the water supply pipes 32a and 32b. Further, the temperature management of the cleaning water W and the transport speed of the transport conveyor 27 are controlled by the control device 45.

  The tableware D cleaned by the rough cleaning unit 22 and the main cleaning unit 23 is transported to the rinse cleaning unit 24, and the detergent is washed away by the clean water sprayed from the upper nozzle 35 and the lower nozzle 36. It is carried out of the cleaning device 1.

  In such a series of flows, the cleaning water W sprayed from the upper nozzle 33a and the lower nozzle 34a disposed in the rough cleaning section 22 in the cleaning chamber 2 and the main cleaning section 23 are disposed. The washing water W sprayed from the upper nozzle 33b and the lower nozzle 34b hits the tableware D to wash away dirt adhering to the tableware D. And it returns to each tank 7a, 7b as it is, and it collects and recycles, or flows into the overflow receiving part 73a, 73b, 73b ', and is discharged | emitted.

  A part of the sprayed washing water W adheres to the inner wall of the upper cover 4 and the door 5 when it hits the tableware D and the conveyor 26 and is scattered to the periphery, and flows down downward as it is. Also, the cleaning water W heated in the tank 7 is sprayed from the upper nozzle nozzle 33 and the lower nozzle 34 to fill the cleaning chamber 2 with steam, and the steam touches the inner walls of the upper cover 4 and the door 5. As a result, the water droplets flow down toward the bottom of the upper cover 4 and the door 5.

  In this way, most of the washing water W that has reached the bottom 43 of the upper cover 4 and the bottom 51 of the door 5 flows down into the tank 7, but the bottom 43 and the door 5 of the upper cover 4. There is also cleaning water W that enters the gap between the bottom portion 51 of the base plate and the mounting portion 81 of the flange portion 8 and remains without falling into the tank 7 due to the action of surface tension.

  In this case, the cleaning water W remaining between the bottom 43 of the upper cover 4 and the bottom 51 of the door 5 and the mounting portion 81 of the flange 8 will be described with reference to FIG. However, in a portion where the bottom 43 of a part of the upper cover 4 and the mounting portion 81 of the flange 8 of the tank 7 are fixed, the space between the bottom 43 of the upper cover 4 and the mounting portion 81 of the flange 8 Since there is almost no gap, and there is little washing water W entering the gap, the washing water W stayed between the bottom 51 of the door 5 which is not fixed and the mounting portion 81 of the flange 8 of the tank 7 is concerned. I will explain.

  In addition, as shown in FIG.5 (b), the washing | cleaning water W which entered between the door opening part 41 and the door 5 ran out to the outer surface side of the washing chamber 2 along the side part 52 of the door 5, and flowed down, It is also conceivable that after entering the space between the bottom 51 of the door 5 and the mounting portion 81 of the flange portion 8 of the tank 7, the air flows out of the cleaning device 1 again.

  First, in order to wash the tableware D in the cleaning chamber 2, since the nozzles 33, 34, 35, and 36 are sprayed, a turbulent air flow is generated in the cleaning chamber 2 by the momentum of the cleaning water W. As a result, a pressure is generated to push the air in the cleaning chamber 2 out of the cleaning device 1. At this time, a pressure for pushing out the air in the cleaning chamber 2 is also generated in the gap between the bottom portion 51 of the door 5 and the placement portion 81 of the flange portion 8 of the tank 7.

  Therefore, the cleaning water 1 that has entered the space between the bottom 51 of the door 5 that overlaps without flowing toward the inside of the tank 7 and the mounting portion 81 of the flange 8 of the tank 7 is washed by the pressure in the cleaning chamber 1. It is pushed out.

  However, by providing the rising portion 82 that is bent upward from the tip of the mounting portion 81, the mounting portion 81 is provided even if pressure is generated to push the air in the cleaning chamber 2 out of the cleaning device 1. The cleaning water W staying between the door 5 and the bottom portion 51 of the door 5 does not reach the start-up portion 82 and is retained between the door 5 and the start-up portion 82.

  Further, for the cleaning water W that has flowed down the outer surface side of the cleaning chamber 2 through the side portion 52 of the door 5, the rising portion 82 is positioned outward from the outer surface side of the cleaning chamber 2, It does not get over the rising portion 82, flows inward from the rising portion 82, and is eventually fastened by a gap between the bottom 51 of the door 5 and the mounting portion 81 of the flange 8.

  For this reason, the cleaning water W cleaning the tableware D in the cleaning chamber 2 enters between the bottom portion 51 of the door 5 and the mounting portion 81 of the flange portion 8 of the tank 7 and remains. Even so, the cleaning water W that has stopped remaining due to the action of the surface tension always flows toward the inside of the tank 7, and the cleaning water W can be prevented from leaking out of the cleaning device 1.

  Further, in order to prevent the water in the tank 7 from getting over and leaking outside by the water return 72 of the tank 7, the wash water W leaks by having the water return 72 in addition to the collar portion 8. Can be prevented more effectively.

  Further, when a plurality of tanks 7 a and 7 b are provided in the cleaning device 1, the cleaning water W leaks from a gap generated between the adjacent rising portions 82, and the decorative plate 65 is streaked. There is a risk that the appearance of 1 will be soiled. However, since the leak-proof plate 9 covers all the rising portions 82 and closes the gaps, water leakage from any portion of the rising portions 82 is prevented. For this reason, even the cleaning device 1 having a plurality of tanks 7 can reliably prevent water leakage to the outside of the cleaning device 1 and maintain a clean state without contaminating the appearance of the cleaning device 1. .

  Moreover, since the rising part 82 is covered from the top by the leak-proof board 9, the rising part used as the front-end | tip part of the collar part 8 which the operator bent and formed one board from the exterior of the washing | cleaning apparatus 1 is used. Injury due to hooking a finger or the like can be prevented without directly touching 82.

  Further, when the door 5 is removed from the door opening 41, the gap between the bottom 51 of the door 5 and the mounting portion 81 of the flange 8 is increased by temporarily lifting the door 5 from the door opening 41, and remains in the meantime. Since the washing water W flows down to the mounting portion 81 side of the collar portion 8 and further to the tank side without getting over the start-up portion 82, the water leaks out of the washing apparatus 1 and the appearance is contaminated. Can be prevented.

  The rising portion 82 of the flange portion 8 is formed so as to cover the vicinity of the lower portion of the upper cover 4 and the door 5. Thereby, when the door 5 is mounted on the door opening 41 of the upper cover 4, the rising portion 82 of the flange 8 is configured so that the bottom 51 of the door 5 placed on the placement portion 81 of the flange 8 is a cleaning device. The door 5 can be prevented from being detached from the door opening 41.

  Further, the short side piece 91 of the leak-proof plate 9 is in contact with the inside of the rising portion 82 of the flange portion 8, and the tip thereof is located up to the placement portion 81. Thereby, the clearance gap between the bottom part 51 of the door 5 and the mounting part 81 of the collar part 8 can be decreased, and the quantity of the washing water W which tends to stay in the meantime can be decreased.

  On the other hand, the long side piece 92 of the leak-proof plate 9 is in contact with the outside of the rising portion 82, and the tip thereof is located below the placement portion 81, and the upper portion of the decorative plate 65 attached to the water storage chamber 6. Covered to support. As a result, the long side piece 92 of the leak-proof plate 9 only supports the top of the decorative plate 65, so that all the decorative plates 65 covering the water storage chamber 6 can be installed without falling down, and can be easily attached and detached. be able to.

  The upper cover 4 covering the cleaning chamber 2 is provided with a door 5 for opening the cleaning chamber 2, but has a bottom similar to the door 5 for opening other portions. Things may be wearable.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment, In the range which does not deviate from the objective of this invention, it can change suitably.

  In the cleaning device of the present embodiment, a continuous type is used. However, the present invention is not limited to this, and a batch type cleaning device can achieve the same effects.
