  However, since the thing described in the said patent document 1 immerses all the bowls (storage implements) which stored the tableware in the immersion tank, immersion tank itself becomes large and it is necessary to store a lot of washing water here In addition, there is a need to remove soil components from the stored washing water, or to replace them with clean washing water. In addition, there are many components such as a dipping tank itself, a lift mechanism that moves up and down a bowl that contains tableware, and a jet cleaning part that is taken out of the dipping tank and washed with water from the nozzle, which makes the entire cleaning apparatus large and complicated. . Furthermore, it is necessary to immerse the ridge in the immersion tank for a predetermined time, and there is a problem that the time required for the entire cleaning becomes long.

  In addition, the structure described in Patent Document 2 has a complicated structure because the cleaning tub is rotated by the spraying power of the cleaning water sprayed from the nozzle to the cylindrical cleaning tub in which the object is to be cleaned. Noise caused by rotation is large. Furthermore, since the object to be cleaned is put in and out of the cylindrical cleaning rod each time, there are problems such as complicated handling and unsuitable for continuous cleaning.

  An object of the present invention is to solve the above-described conventional problems, and to efficiently clean an object to be cleaned, and to reduce the size of the cleaning device and simplify the configuration.

  In order to solve the above-described conventional problems, a cleaning method of the present invention provides a storage tool for storing an object to be cleaned, transport means for transporting the storage tool, and a predetermined interval along the transport direction of the storage tool. A plurality of nozzles for injecting cleaning water, and for each of the plurality of arranged nozzles, the cleaning water is sequentially sprayed from the upper side of the container to be transported, and the sprayed cleaning water is an abbreviation of an object to be cleaned. A predetermined amount of water is stored in the storage device so as to be immersed in the storage device and drained out of the storage device, and the object to be cleaned is sequentially washed along the transport direction of the storage device.

  According to the cleaning method of the present invention, the object to be cleaned can be efficiently cleaned, and the size and configuration of the cleaning device can be simplified.

  A first invention is a storage device for storing an object to be cleaned, a transport means for transporting the storage device, and a nozzle for injecting a plurality of cleaning waters arranged at predetermined intervals along the transport direction of the storage device. And for each of the plurality of nozzles arranged, the cleaning water is sequentially ejected from the upper side of the container to be transported, and the sprayed cleaning water is immersed in the container so that substantially the entire object to be cleaned is immersed therein. The cleaning method is characterized by draining outside the storage tool while storing a predetermined amount of water, and sequentially cleaning the object to be cleaned along the transport direction of the storage tool.

  In the cleaning method of the present invention, the immersion cleaning action in the storage tool by storing water so that substantially the entire object to be cleaned is immersed in the storage tool that stores the cleaning object, and the cleaning water in the storage tool in order. Intense fluidization of the cleaning water in the storage device by discharging water while spraying and storing water, and cleaning of the cleaning water itself to be cleaned by sequentially injecting cleaning water from the upper side of the storage device A direct abutting action on an object can be generated in combination. Further, the combined action can be generated a plurality of times at the position of the nozzle for injecting a plurality of cleaning waters arranged at predetermined intervals along the conveying direction of the storage tool. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  Furthermore, when a separate immersion cleaning tank is provided as in the prior art and the storage tool is sequentially immersed in the cleaning water, dirt components increase in the cleaning water in the immersion cleaning tank and the cleaning action decreases. become. 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 sprayed from the upper side of the storage tool and drained out of the storage tool together with the dirt component while storing water in the storage tool. Clean water is always stored inside. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  In addition, an immersion cleaning tank is provided separately for a predetermined time (for example, 10 minutes) by the immersion cleaning action in the storage tool by storing water so that substantially the entire target object is immersed in the storage tool that stores the cleaning object. Degree) The step of immersing the storage device storing the object to be cleaned is not necessary. Therefore, also from this point, the object to be cleaned can be efficiently cleaned.

  As described above, it is not necessary to provide a separately fixed immersion cleaning tank, that there is no need for a mechanism for putting the storage tool in and out of the immersion cleaning tank, and that it is only necessary to transport the storage tool in the horizontal direction. The entire cleaning apparatus can be reduced in size and the configuration can be simplified.

  A second aspect of the invention is the cleaning method according to the first aspect of the invention, wherein the cleaning water sprayed from the nozzle is drained out of the storage tool as an overflow at the lower side of the water storage and at the level of water stored while storing a predetermined amount of water. It is what.

  Accordingly, it is possible to efficiently wash the object to be cleaned by fluidizing the cleaning water in multiple directions in the storage tool. Further, relatively heavy components can be discharged from the lower side of the stored water, and light components can be quickly discharged out of the storage device together with overflowing water, so that the washing water stored can be kept clean. Furthermore, after washing, the water can be quickly drained from the lower side of the stored water to the outside of the storage tool. Accordingly, sterilization and drying, which are steps after washing, can be performed efficiently, and the complexity of handling the storage tool can be eliminated.

  According to a third aspect of the present invention, in the first or second aspect of the invention, the cleaning method includes a cleaning step in which the water level for storing the cleaning water sprayed from the nozzle in the storage device is lowered in the transport direction of the storage device, It is a thing.

  This enhances the direct contact action of the spray cleaning water itself on the object to be cleaned exposed to the stored water level and promotes the separation of dirt components from the object to be cleaned. Cleaning of the entire apparatus can be performed more efficiently. The means for lowering the level of water stored can be easily adjusted by balancing the amount of washing water sprayed from the nozzle with the amount of water drained from the lower side of the stored water to the outside of the storage device.

  A fourth invention is a cleaning method according to any one of the first to third inventions, wherein the object to be cleaned is chopsticks.

  This makes it possible to reliably and efficiently clean the chopsticks that are rod-shaped bodies.

  The lid portion 23 has a frame 24 made of a wire rod on the outside, and a plurality of wire rods 25 and 26 fixed vertically and horizontally inside the frame 24. The lid portion 23 and the storage portion 15 are held by a plurality of rotating members 27, and the lid portion 23 is configured to be openable and closable with respect to the storage portion 15.

  A plurality of chopsticks 28 as objects to be cleaned are stacked on the bottom plate 17 of the storage unit 15 in a plurality of stages, and the chopsticks 28 are stored so that the ends in the longitudinal direction (axis length direction) are located on the openings 18 and 19 side. To do. In addition, a plurality of chopsticks 28 are stacked on the bottom plate 17 in a plurality of stages, and the upper end of the stacked chopsticks 28 is stored with a margin so as to have a predetermined distance from the lid 23.

  Furthermore, the dimension between both ends in the longitudinal direction of the chopsticks 28 is made shorter than the interval between the vertical walls 16b and 16d, and the chopsticks 28 are stored with a margin so that they can move within a predetermined range in the longitudinal direction. This is to store the chopsticks 28 with a margin so that the chopsticks 28 do not rotate greatly in the longitudinal direction, and the chopsticks 28 can move within a predetermined range within a range where the chopsticks 28 are substantially aligned in the longitudinal direction.

  In addition, a handle 20 is provided so that the storage tool 14 is portable. The fixing position of the handle 20 to the storage tool 14 is not limited to the configuration of the embodiment, and may be provided at an arbitrary position.

  The storage tool 14 moves in the cleaning space 7 so that the longitudinal direction of the stored chopsticks 28 is substantially orthogonal to the moving direction of the storage tool 14. Further, since the short sides (t1) of the nozzles 10 and 11 are arranged along the moving direction of the storage tool 14, the narrower cleaning water is sequentially ejected in a direction substantially orthogonal to the longitudinal direction of the chopsticks 28. .

  Next, the cleaning state of the chopsticks 28 will be described with reference to FIGS. In the figure, W indicates the flow of the injected cleaning water, and indicates the flow of the cleaning water injected into the storage device 14 and the outflow path to the outside of the storage device 14 by solid arrows and Fa and Fb.

  FIG. 8A shows a cleaning state when the cleaning water from the nozzles 10 and 11 reaches the front part in the transport direction of the storage unit 15 by the movement of the storage tool 14.

The cleaning water (w) having a predetermined spray speed from the nozzles 10 and 11 pushes the portion of the chopsticks 28 to which the cleaning water hits downward, and a part of the chopsticks 28 moves in the storage unit 15 in the direction where the cleaning water is not sprayed. .
At this time, the lid 23 prevents the jumping out of the storage unit 15 and holds it in the storage unit 15.

  The washing water sprayed into the storage unit 15 is stored in the storage unit 15 and flows as indicated by solid arrows, and overflows (Fa) from the upper ends of the vertical walls 16a, 16b, 16c, and 16d of the storage unit 15. leak. Further, as shown in FIG. 9, the water is stored in the storage unit 15 and flows downward from the openings 18 and 19.

  The amount of washing water from the nozzles 10 and 11 is set so that the overflow (Fa) flows out from at least the upper ends of the vertical walls 16a, 16b, 16c and 16d at the same time as flowing downward from the openings 18 and 19. When the cleaning water is sprayed from the nozzles 10 and 11 into the storage unit 15, the water is always stored in the storage unit 15. That is, the areas of the openings 18 and 19 are set so that the overflow (Fa) flows out from the upper ends of the vertical walls 16a, 16b, 16c, and 16d with respect to the amount of the cleaning water sprayed from the nozzles 10 and 11 into the storage unit 15. That's fine.

  In the state of FIG. 8A, the portion of the chopsticks 28 to which the cleaning water hits is pushed downward, and a part of the chopsticks 28 moves in the storage unit 15 in the direction in which the cleaning water is not jetted, and the stored cleaning water storage unit The plurality of chopsticks 28 housed in the housing portion 15 are rotated by the rotating flow in the housing 15. In addition, the plurality of chopsticks 28 move and rotate in the storage unit 15, and the individual chopsticks 28 rotate while being rubbed with each other.

  Furthermore, the dimension between both ends in the longitudinal direction of the chopsticks 28 is shorter than the interval between the vertical walls 16b and 16d, and the chopsticks 28 are accommodated so as to be movable within a predetermined range in the longitudinal direction. Individual chopsticks 28 move in the longitudinal direction and rub against each other.

  As a result, the dirt adhering to the surface of the chopsticks 28 can be reliably and efficiently removed and cleaned. The removed dirt component is discharged out of the storage unit 15 together with the cleaning water that flows downward from the openings 18 and 19 and the cleaning water that flows out as overflow (Fa) from the upper ends of the vertical walls 16a, 16b, 16c, and 16d. Further, the cleaning water is replenished from the nozzles 10 and 11 and the stored water is maintained, so that it is always replaced with clean cleaning water, and the removed dirt component does not stay in the storage unit 15.

  FIG. 8B shows a cleaning state when the cleaning water from the nozzles 10 and 11 reaches the substantially central portion in the transport direction of the storage unit 15 by the movement of the storage tool 14.

  Washing water (w) having a predetermined spray speed from the nozzles 10 and 11 causes the chopsticks 28 in the portion to which the cleaning water hits to be pushed downward to move to both sides in the storage unit 15 where no cleaning water is jetted. To do.

  The washing water sprayed into the storage unit 15 is stored in the storage unit 15 and flows as indicated by solid line arrows. The washing water stored in the storage unit 15 overflows from the upper ends of the vertical walls 16a, 16b, 16c, and 16d of the storage unit 15 while forming two circulating flows that convect in the storage unit 15 as indicated by solid arrows. Fa) flows out, and further flows out downward from the openings 18 and 19 along the longitudinal direction of the chopsticks 28 as shown in FIG.

  The state of FIG. 8C shows a cleaning state when the cleaning water from the nozzles 10 and 11 reaches the rear part in the transport direction of the storage unit 15 due to the movement of the storage tool 14.

  In the state of FIG. 8C, the portion of the chopsticks 28 to which the cleaning water hits is pushed downward to move in the storage unit 15 in a direction in which the cleaning water is not jetted, and in the storage unit 15 of the stored cleaning water. Due to the rotating flow, the entire stored chopsticks 28 also rotate within the storage portion 15. In addition, the plurality of chopsticks 28 move and rotate in the storage unit 15, and the individual chopsticks 28 rotate while being rubbed with each other.

  As described above, the cleaning operation shown in FIGS. 8 and 9 is repeated for each of the plurality of arranged nozzles 10 and 11 to complete the cleaning of the chopsticks 28 stored together with the storage tool 14. The chopsticks 28 that have been washed are stored in the storage tool 14 by being dried, sterilized, or the like in the next step.

  Although not shown, the storage tool 14 is reciprocated by the driving means from one direction to clean the chopsticks 28, or the storage tool 14 is fixed and the nozzles 10, 11 are reciprocated by the driving means. By cleaning the chopsticks 28, it is possible to reduce the size of the cleaning device and save space.

  FIG. 10 shows a configuration in which the bottom plate 17 is formed with an opening 19 for washing water outflow only on the vertical wall 16d side. As a result, the wash water stored in the storage unit 15 flows out as overflow (Fa) from the upper ends of the vertical walls 16a, 16b, 16c, and 16d of the storage unit 15, and further downward from the opening 19 along the longitudinal direction of the chopsticks 28. It will be in a state of flowing out. In the configuration shown in FIG. 10, the fluid flows in one direction along the longitudinal direction of the plurality of chopsticks 28 and flows downward from the opening 19.

  When a plurality of objects to be cleaned are chopsticks 28, the tapered tip end portion sandwiching the food is set as the opening 19 side, and the handle portion is stored in the storage portion 15 in the direction without the opening. As a result, the tip of the tapered portion where the dirt adheres is located on the opening 19 side, and the removed dirt quickly flows out from the opening 19 together with the washing water stored in water, so that the washing water stored in the storage part 15 is discharged. The diffusion of dirt components to the whole is reduced, and the cleanliness of the cleaning water stored in the storage unit 15 can be further increased.

  In FIG. 11, the storage unit 15 has vertical walls 16a, 16b, 16c, and 16d, and a gap 30 is formed above the bottom plate 17 in the interior surrounded by the vertical walls 16a, 16b, 16c, and 16d. Is configured to be fixed to the vertical walls 16a, 16b, 16c, 16d or the bottom plate 17. The porous body 29 is composed of a punching plate having a large number of small holes or a wire mesh. A plurality of chopsticks 28, which are objects to be cleaned, are stacked on the porous body 29 over a plurality of stages, and the chopsticks 28 are stored so that the ends in the longitudinal direction (axial length direction) are located on the openings 18 and 19 side.

  In the configuration of FIG. 11, a part of the cleaning water stored in the storage unit 15 flows through the gaps in the axial direction of the plurality of stacked chopsticks 28 and passes below the porous body 29 and enters the gap 30 to enter the gap. It flows through the inside 30 and flows out from the openings 18 and 19.

  Dirt removed from the plurality of chopsticks 28 quickly flows out of the porous body 29 together with the washing water stored in water and flows out from the openings 18 and 19, so that the dirt components are diffused throughout the washing water stored in the storage unit 15. And the cleanliness of the cleaning water stored in the storage unit 15 can be further increased. Note that the gap 30 between the bottom plate 17 and the porous body 29 may be set to 3 to 5 millimeters, for example.

  In the embodiment, the object to be cleaned is described as the chopsticks 28. However, the present invention is not limited to this, and can be applied to various other objects to be cleaned.

  As described above, in the cleaning method of the present invention, the immersion cleaning action in the storage tool by storing water so that substantially the entire target object is immersed in the storage tool that stores the target object, The washing water is ejected sequentially and drained while being stored, and the fluid is intensively fluidized in the storage device, and the cleaning water is sprayed from the upper side of the storage device in order to spray the object to be cleaned. A direct abutting action of water itself on an object to be cleaned can be generated in combination. Further, the combined action can be generated a plurality of times at the position of the nozzle for injecting a plurality of cleaning waters arranged at predetermined intervals along the conveying direction of the storage tool. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  Furthermore, when a separate immersion cleaning tank is provided as in the prior art and the storage tool is sequentially immersed in the cleaning water, dirt components increase in the cleaning water in the immersion cleaning tank and the cleaning action decreases. become. 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 sprayed from the upper side of the storage tool and drained out of the storage tool together with the dirt component while storing water in the storage tool. Clean water is always stored inside. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  In addition, an immersion cleaning tank is provided separately for a predetermined time (for example, 10 minutes) by the immersion cleaning action in the storage tool by storing water so that substantially the entire target object is immersed in the storage tool that stores the cleaning object. Degree) The step of immersing the storage device storing the object to be cleaned is not necessary. Therefore, also from this point, the object to be cleaned can be efficiently cleaned.

  As described above, it is not necessary to provide a separately fixed immersion cleaning tank, that there is no need for a mechanism for putting the storage tool in and out of the immersion cleaning tank, and that it is only necessary to transport the storage tool in the horizontal direction. The entire cleaning apparatus can be reduced in size and the configuration can be simplified.

  In addition, while storing a predetermined amount of washing water sprayed from the nozzle, it is drained out of the storage tool as overflow at the lower side of the water storage and at the water level to be stored. Accordingly, it is possible to efficiently wash the object to be cleaned by fluidizing the cleaning water in multiple directions in the storage tool. Further, relatively heavy components can be discharged from the lower side of the stored water, and light components can be quickly discharged out of the storage device together with overflowing water, so that the washing water stored can be kept clean. Furthermore, after washing, the water can be quickly drained from the lower side of the stored water to the outside of the storage tool. Accordingly, sterilization and drying, which are steps after washing, can be performed efficiently, and the complexity of handling the storage tool can be eliminated.

  In addition, the cleaning process in which the cleaning water sprayed from the nozzle is stored in the storage tool is lowered to include the cleaning process in the transport direction of the storage tool, thereby spraying the object to be cleaned exposed above the stored water level. The direct contact action of the water itself with the object to be cleaned is strengthened, and the peeling of the dirt component from the object to be cleaned is promoted, so that the cleaning apparatus as a whole can be more efficiently cleaned. The means for lowering the level of water to be stored can be easily adjusted by balancing the amount of washing water jetted from the nozzle with the amount of water discharged from the lower side of the stored water to the outside of the storage device.

  The present invention is not limited to tableware, and can also be applied to cleaning objects to be cleaned such as machined parts.
