The nozzles 10 and 11 are arranged with a predetermined angle (θ1) with respect to the vertical plane as shown in FIG. The predetermined angle (θ1) of the nozzles 10 and 11 is set to, for example, approximately 10 degrees with respect to the vertical plane.

  In the cleaning space 7, a water storage unit 14 that stores the tub 18 along the moving direction of the conveyor 2 is located on the conveyor 2, and the cleaning space 7 starts from the inlet side of the water storage unit 14 to the rough cleaning zone 7 a, intermediate The cleaning process is divided into cleaning zones 7b and 7c and a finishing cleaning zone 7d. Each cleaning zone is provided with at least one tank 8 for storing cleaning water, a pump 9 and nozzles 10 and 11 as one unit. The classification and number of cleaning zones, and the number of tanks 8, pumps 9, and nozzles 10 and 11 disposed in each cleaning zone are merely examples, and the present invention is not limited to this.

  The shape of the nozzles 10 and 11 for injecting the cleaning water shown in FIGS. 3A and 3B has a rectangular opening cross section, and the short side (t1) is along the moving direction of the water storage unit 14 and is long. The side (t2) is arranged in a direction substantially orthogonal to the moving direction of the water storage unit 14.

  The water storage unit 14 shown in FIG. 4 is formed in a cylindrical square shape with vertical walls 15a, 15b, 15c, and 15d, and bottom plates 16a and 16b are fixed to the lower portion. An opening 17 is formed between the bottom plates 16a and 16b, and the bottom plates 16a and 16b are inclined so that the side of the opening 17 is lower. The upper part of the water storage unit 14 formed into a cylindrical shape by the vertical walls 15a, 15b, 15c, and 15d is in an open state. A storage portion 15 for the jar 18 is configured in the water storage unit 14. The water storage unit 14 is made of metal such as stainless steel or resin.

  5 is configured in a cylindrical square shape using, for example, a wire made of stainless steel or the like, and a lower portion below the plurality of dishes 20 is provided. It has the support bodies 19a and 19b which support the peripheral edge part of the above-mentioned along a pile direction. The dish 20 is taken in and out through the opening at the top of the cylindrical bowl 18. The number of supports 19a and 19b is only an example, and a larger number of supports may be provided. Note that all of the components of the ridge 18 are configured such that the wash water can flow without resistance.

  When a plurality of dishes 20 are stacked with their surfaces facing up, a plurality of dishes 20 are provided with respect to the distance between all the dishes 20 on the front surface side of the dish 20 located at the top and the rear surface side of the dish 20 located at the rearmost side. Is stored in the basket 18 by giving a distance of, for example, 10 to 20 millimeters with respect to the distance between all the dishes 20.

  As a result, the supports 19a and 19b are accommodated in such a manner that the plurality of dishes 20 slide and move within the distance of 10 to 20 millimeters. Further, the plurality of dishes 20 are inclined at a predetermined angle in the same direction.

  The cross-sectional block diagram of the water storage unit 14 when the jar 18 is accommodated in FIG. 6 is shown. The outer dimension of the jar 18 is configured to be smaller than the inner dimension of the water storage unit 14, and the jar 18 can be accommodated in the water storage unit 14 from the upper part of the water storage unit 14. Further, the bottom surface of the flange 18 is placed on the bottom plates 16a and 16b. In addition, when the tub 18 is accommodated in the water storage unit 14, the longitudinal direction of the opening 17 provided in the water storage unit 14 is a direction along the stacking direction of the plurality of dishes 20.

  In addition, when the basket 18 is accommodated in the water storage unit 14, the upper ends of the vertical walls 15 a, 15 b, 15 c, and 15 d of the water storage unit 14 are positioned higher than the upper ends of the plurality of dishes 20. For example, a slit hole (not shown) may be formed in the upper part of the vertical walls 15a, 15b, 15c, 15d, and the lower end of the slit hole may be higher than the upper ends of the plurality of dishes 20. Good.

  The water storage unit 14 is made of a metal such as stainless steel or a resin. However, the entire water storage unit 14 is made of a resin or rubber material having elasticity, and is attached to the outer surface of the rod 18. May be. In this case, the water storage unit 14 is more compact, and the outer surface of the ridges 18 can be protected and the impact caused by contact between the ridges 18 or other objects can be reduced.

  Next, the state at the time of washing | cleaning of the dish 20 in the washing | cleaning apparatus 1 is demonstrated using FIGS. The state at the time of cleaning shown in FIGS. 7 and 8 is such that the stacking direction of the plurality of dishes 20 stored in the basket 18 is along the conveying direction of the water storage unit 14 by the conveyor 2, and the entrance side starts with the surface side of the dishes 20 at the top. To the rough cleaning zone 7a, the intermediate cleaning zones 7b and 7c, and the finishing cleaning zone 7d are transported and sequentially cleaned.

  In addition, W in the figure indicates cleaning water sprayed from the nozzles 10 and 11, Wa is cleaning water drained downward from the opening 17 of the water storage unit 14, and Wb is drained as overflow water from the upper end of the water storage unit 14. Indicates the washing water to be used. Solid arrows indicate the flow of wash water.

  Since the short sides (t1) of the nozzles 10 and 11 are arranged along the moving direction of the storage tool 14 (the stacking direction of the dishes), washing water having a narrower width is sequentially ejected in the stacking direction of the dishes 20. .

  Wash water (W) sprayed into the water storage unit 14 is stored in the water storage unit 14, and the stored wash water is drained downward from the opening 17 of the water storage unit 14 and the water storage unit. The washing water (Wb) drained as overflow from the upper end of 14 flows as indicated by solid line arrows.

  The amount of cleaning water sprayed into the water storage unit 14 from the nozzles 10 and 11 is set to be larger than the amount of cleaning water (Wa) discharged from the opening 17 of the water storage unit 14 and discharged downward. The washing water is always stored at the water level up to the upper end of the water storage unit 14. A part of the stored washing water flows out and drains as overflow water (Wb).

  The wash water (W) jetted at high speed from the nozzles 10 and 11 by the high-pressure pump 9 passes through the surface of the stored wash water and reaches the upper peripheral edge of the dish 20. Entering between the peripheral ends, the dynamic pressure and static pressure of the washing water (W) act on the back side and the front side of the plate 20 to push and spread the plates 20 adjacent to each other. At this time, the plurality of dishes 20 change from an inclined posture to a vertical posture.

  Thereby, the plates 20 adjacent to each other are separated in the stored washing water. Wash water (W) sprayed from the nozzles 10 and 11 flows while pushing away the stored wash water in the spaced intervals. When the dishes 20 stored in the basket 18 together with the water storage unit 14 move in the overlapping direction, the dishes 20 adjacent to each other are sequentially separated from the surface side of the dish 20 located at the head.

  The cleaning water (W) sprayed from the nozzles 10 and 11 flows while pushing away the stored cleaning water in the above-mentioned spaced intervals, so that the dirt on the back side and the front side of the dish 20 is surely removed. .

  Further, the cleaning water sprayed from the nozzles 10 and 11 is drained downward (Wa) from the opening 17 of the water storage unit 14 while being stored in the water storage unit 14, so that the cleaning water (W) sprayed from the nozzles 10 and 11 and The wash water stored in the water storage unit 14 flows from the upper part of the dish 20 to the lower part.

  Further, since the opening 17 is formed at the lower center of the dish 20, the cleaning water (W) sprayed from the nozzles 10 and 11 and the cleaning water stored in the water storage unit 14 are surely along the upper part to the lower part of the dish 20. To flow. Thereby, the dirt of the plurality of dishes 20 stored in the basket 18 is more efficiently removed.

  Further, the cleaning water (W) sprayed from the nozzles 10 and 11 after the cleaning in the cleaning device 1 and the cleaning water stored in the water storage unit 14 can be quickly drained out of the water storage unit 14 through the opening 17. Accordingly, it is possible to efficiently sterilize and dry the dish 20 as a process after washing, and to eliminate the troublesome handling of the water storage unit 14 and the drainage of the basket 18. Further, the bottom plates 16a and 16b forming the opening 17 are inclined so that the opening 17 side is lowered, so that the water can be drained more quickly.

  Further, the washing water sprayed from the nozzles 10 and 11 is drained as overflow from the lower part of the water storage unit 14 and the upper part of the water storage unit 14 while being stored in the water storage unit 14. Accordingly, the washing water can be fluidized in multiple directions in the water storage unit 14 and the dish 20 can be washed efficiently. In addition, it is possible to keep the cleaning water to be kept clean by discharging dirt of components having a relatively high specific gravity from the lower side of the water storage, and discharging dirt of components having a low specific gravity together with overflow to the outside of the water storage unit 14 quickly.

  Further, since the tub 18 itself is also accommodated in the water storage unit 14, it can be cleaned by the flow of the cleaning water sprayed from the nozzles 10 and 11 and the cleaning water stored in the water storage unit 14, and adheres to the basin 18. The removed dirt can be removed efficiently.

  Further, conventionally, the cleaning water is sprayed from the nozzle onto the tableware (dish) taken out of the immersion tank and stored in the table, and the cleaning water is scattered on the tableware. In addition, there is a problem that the washing water sprayed from the nozzle hardly flows over the entire surface of the tableware, and the entire amount of the washing water sprayed from the nozzle is not effectively used for washing the tableware.

  On the other hand, in the cleaning method of the present invention, the cleaning water sprayed from the nozzles 10 and 11 is reliably captured in the water storage unit 14 and, as described above, the cleaning water (W) sprayed from the nozzles 10 and 11. The washing water stored in the water storage unit 14 flows reliably from the upper part of the dish 20 to the lower part. As a result, the cleaning water sprayed from the nozzles 10 and 11 can effectively and effectively remove the dirt by cleaning the scissors 18 and the plurality of dishes 20 stored in the scissors 18 without waste.

  As described above, it is not necessary to provide a separately fixed immersion cleaning tank, there is no need for a mechanism for taking in and out the tub containing the object to be cleaned, and the tub storing the object to be cleaned is stored. By only transporting the water storage unit 14 in the horizontal direction, the entire cleaning device can be downsized and the configuration can be simplified.

  Furthermore, conventionally, by sequentially immersing the basket containing the object to be cleaned in a fixed dip cleaning tank, dirt components increase in the cleaning water in the dip cleaning tank, and the dip cleaning action decreases. For this reason, it is necessary to periodically replace the cleaning water in the immersion cleaning tank.

  On the other hand, in the cleaning method of the present invention, clean cleaning water is jetted from the upper side of the water storage unit 14 and continuously drained out of the water storage unit 14 together with dirt components while storing the water in the water storage unit 14. In the water storage unit 14, clean wash water is always stored. As a result, dirt on the dish 20 can be reliably removed and cleaning can be performed efficiently.

  In addition, an immersion cleaning tank is separately provided for a predetermined time (for example, 10 to 20 minutes) by a dipping action in the water storage unit 14 by storing water so that substantially the entire dish 20 is immersed in the water storage unit 14. A step of immersing the stored basket 18 becomes unnecessary. Therefore, also from this point, the dish 20 can be efficiently cleaned.

  Furthermore, by allowing the bowl 18 containing the dish 20 to be accommodated in the water storage unit 14, the bowl 18 containing the dish 20 to be cleaned is accommodated in the water storage unit 14 before washing in the cleaning device 1. After cleaning, after the cleaning, the basket 18 storing the object to be cleaned can be taken out from the water storage unit 14, and the general purpose one can be used as it is for storing the object to be cleaned.

  As described above, the cleaning method of the present invention is carried out in the water storage unit 14 by storing water so that substantially the whole of the dish 20 is immersed in the water storage unit 14 that houses the bowl 18 that houses the dish 20 to be cleaned. , The replacement action to clean washing water by spraying washing water into the moving water storage unit 14 and draining it while storing it, and the washing water stored in the entire water storage unit 14 touching the dish 20 The fluid fluidizing action, the rocking action of the dish 20 in the stored water, and the direct contact action of the cleaning water itself on the dish 20 by sequentially ejecting the cleaning water from the upper side of the water storage unit 14. It can be generated in combination.

  Further, the combined action can be continuously generated by a change in the injection position of the washing water from the nozzles 10 and 11 due to the movement of the water storage unit 14. Further, it can be generated a plurality of times at the positions of the nozzles 10 and 11 for injecting a plurality of cleaning waters arranged along the transport direction of the water storage unit 14. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  Next, the cleaning state shown in FIG. 9 will be described. FIG. 9 shows a state in which the wash water sprayed from the nozzles 10 and 11 is stored in the water storage unit 14, and the water level is lowered and the dish 20 as the object to be cleaned is exposed above the stored water level. is there. In this state, an example is shown in which the water level for storing water is a position approximately half the diameter of the dish 20.

  The means for lowering the level of water stored and maintaining this level can be easily adjusted by balancing the amount of washing water jetted from the nozzles 10 and 11 with the amount drained from the lower side of the water storage to the outside of the water storage unit 14. Can do. This adjustment can be performed, for example, by setting the nozzles 10 and 11 to have a smaller opening cross section, maintaining the injection speed, and reducing the injection amount.

  In the cleaning process in the cleaning state shown in FIG. 9, the water stored in the water storage unit 14 is stored outside the water storage unit 14 while the cleaning water sprayed from the nozzles 10 and 11 is immersed in substantially the entire plate 20. In addition to the cleaning step of draining, the cleaning device 1 is configured.

  The washing water sprayed into the water storage unit 14 from the nozzles 10 and 11 flows downward from the opening 17 of the water storage unit 14 and is drained. Washing water (W) jetted at high speed from the nozzles 10 and 11 by the high-pressure pump 9 enters between the peripheral ends of the plates 20 adjacent to each other above the plate 20 exposed above the water level. ) Act on the back side and the front side of the plate 20 to push and spread the plates 20 adjacent to each other. At this time, the dish 20 stored in the basket 18 changes from an inclined posture to a vertical posture.

  Furthermore, the stored wash water passes through the surface of the wash water that enters the space between the adjacent dishes 20, and the wash water stored in this space is pushed downward to flow. Further, when the dishes 20 stored in the basket 18 together with the water storage unit 14 move in the overlapping direction, the adjacent dishes 20 are sequentially separated from the front surface side of the dish 20 located at the head.

  The cleaning water sprayed from the nozzles 10 and 11 flows while pushing away the stored cleaning water in the above-mentioned spaced interval, and the sprayed cleaning water itself directly to the portion of the dish 20 exposed above the stored water level By the abutting action, peeling of the dirt component from the dish 20 can be promoted, so that the cleaning apparatus as a whole can be more efficiently cleaned.

  Next, the cleaning state shown in FIG. 10 will be described. In FIG. 10, the cleaning water sprayed from the nozzles 10 and 11 is not stored in the water storage unit 14, but the sprayed cleaning water itself is brought into direct contact with the exposed portion of the dish 20 for cleaning.

  The means for preventing the cleaning water sprayed from the nozzles 10 and 11 from being stored in the water storage unit 14 balances the injection amount of the cleaning water from the nozzles 10 and 11 with the amount of water discharged from the lower side of the water storage to the outside of the water storage unit 14. Can be adjusted easily. This adjustment can be performed, for example, by setting the nozzles 10 and 11 to have a smaller opening cross section, maintaining the injection speed, and reducing the injection amount.

  Note that the cleaning process in the cleaning state shown in FIG. 10 is performed outside the water storage unit 14 while storing the cleaning water sprayed from the nozzles 10 and 11 in the water storage unit 14 so that substantially the whole of the dish 20 is immersed. In addition to the cleaning step of draining, the cleaning device 1 is configured.

  The washing water sprayed into the water storage unit 14 from the nozzles 10 and 11 flows downward from the opening 17 of the water storage unit 14 and is drained. Washing water (W) jetted at high speed from the nozzles 10 and 11 by the high-pressure pump 9 enters between the peripheral ends of the plates 20 adjacent to each other above the plate 20 exposed above the water level. ) Act on the back side and the front side of the plate 20 to push and spread the plates 20 apart. At this time, the dish 20 stored in the basket 18 changes from an inclined posture to a vertical posture.

  Further, the plates 20 stored in the basket 18 together with the water storage unit 14 move in the overlapping direction, so that the plates 20 adjacent to each other are sequentially separated from the surface side of the plate 20 located at the head. The cleaning water (W) sprayed from the nozzles 10 and 11 flows in the above-mentioned spaced intervals, thereby enhancing the direct contact action of the sprayed cleaning water itself to the exposed parts to be cleaned. The peeling from the object to be cleaned can be promoted, and the cleaning apparatus as a whole can be more efficiently cleaned.

  9 and 10 is preferably used in the finishing cleaning zone 7d after the cleaning in the rough cleaning zone 7a and the intermediate cleaning zones 7b and 7c of the cleaning apparatus 1.

I changed to the posture and washed. On the other hand, in the state at the time of cleaning shown in FIG. 11, the cleaning is performed in the inclined posture when the dish 20 stored in the basket 18 is stored.

  In addition, by adjusting the capacity of the pump 9 and increasing the openings of the nozzles 10 and 11 to maintain the amount of cleaning water sprayed from the nozzles 10 and 11 and lowering the spray pressure, the dish 20 remains in an inclined posture. Can be set to perform cleaning.

  In the state at the time of cleaning shown in FIG. 11, the dish 20 is in an inclined posture, a part of the upper end part of the dish 20 is in contact with each other, and is separated away from each other toward the lower end part. The wash water stored in the water storage unit 14 flows through the lower end portion and is spaced apart from each other, and drains (Wa, Wb) from the lower opening 17 and the upper end portion of the water storage unit 14.

  Since the dish 20 is located in the wash water stored in the water storage unit 14, the plurality of dishes 20 are finely oscillated by the flow of wash water that receives buoyancy and constantly changes. As a result, contact and separation are repeated at locations where the upper end portions of the plate 20 are in contact with each other. By these, the stain | pollution | contamination of the some dish 20 can be efficiently removed like the state at the time of washing | cleaning shown in FIG. 7, FIG. In addition, you may implement the washing | cleaning which reduced the water level shown in FIG. 9, FIG.

  Next, the cleaning state shown in FIG. 12 will be described. In the state at the time of cleaning shown in FIG. 12, the dish 20 as the object to be cleaned is supported by a plurality of support members 19c provided on the basket 18, and is stored in the basket 18 after being separated by a predetermined distance (for example, 10 to 20 mm). Then, the washing water sprayed from the nozzles 10 and 11 is made to flow along the front surface and the back surface in the spaced distance between the adjacent dishes 20 to wash the dishes 20.

  The wash water sprayed from the nozzles 10 and 11 sequentially flows in the interval that is separated in advance, and the wash water stored in the water storage unit 14 simultaneously flows in the interval that the plurality of dishes 20 are separated. To do. Thereby, the dirt of the plurality of dishes 20 can be efficiently removed. In addition, you may implement the washing | cleaning which reduced the water level shown in FIG. 9, FIG.
