By changing the length of time for performing the first cleaning step and / or the second cleaning step. In each cleaning of the object to be cleaned, the total amount of cleaning water sprayed onto the object to be cleaned is adjusted. A cleaning method characterized by the above is provided.
[0015] Thereby, among the plurality of nozzles, the total amount of cleaning water sprayed from the first nozzle and the second nozzle is made different between the first cleaning step and the second cleaning step, and the total amount of cleaning water sprayed onto the object to be cleaned in each cleaning can be equalized.
[0016] And when changing the length of time for performing the first cleaning step and / or the second cleaning step so that cleaning water with a desired total amount is sprayed from a nozzle with a small total amount of cleaning water among the plurality of nozzles in each cleaning, compared with the case where the total amount of cleaning water sprayed from the first nozzle and the second nozzle is not equalized, even if the total amount of cleaning water sprayed from the nozzle is set to the desired total amount, the length of time for performing the first cleaning step and / or the second cleaning step can be shortened.
[0017] As a result, the total amount of cleaning water sprayed from the entire plurality of nozzles can be reduced, and the energy for spraying the cleaning water can be reduced.
[0018] In the second invention, in the first invention, The first flow path and the second flow path are provided in a common pipe, In the first cleaning step, the cleaning water flowing in from the first inlet is stored in the common pipe, For a predetermined time from the start of the second cleaning step, the cleaning water stored in the common pipe is sprayed from the plurality of nozzles This is a cleaning method characterized by the above.
[0019] Thereby, in the second cleaning step, the amount of cleaning water flowing in from the second inlet can be reduced by the amount of the cleaning water stored in the common pipe in the first cleaning step, and the second cleaning step can be started quickly.
[0020] And the cleaning time of the object to be cleaned per time can be made as short as possible, and the energy for spraying the cleaning water can be reduced.

[0022] In the third invention, in the second invention, The cleaning water for cleaning the object to be cleaned by spraying from a plurality of nozzles is The cleaning water flowing from the first inlet to the common pipe is defined as the first cleaning water, The cleaning water flowing from the second inlet to the common pipe is defined as the second cleaning water, For a predetermined time from the start of the second cleaning step, the first cleaning water stored in the common pipe in the first cleaning step is sprayed from the plurality of nozzles This is a cleaning method characterized by the above.
[0023] Thus, from the start of the second cleaning step for a predetermined time, by injecting the first cleaning water stored in the common pipe such that the total amount of the cleaning water injected from the first nozzle and the second nozzle is different from that in the first cleaning step, the total amount of the first cleaning water injected from the first nozzle and the second nozzle per cleaning of the object to be cleaned is equalized, and the degree of cleaning with the first cleaning water can be equalized among a plurality of objects to be cleaned.
[0024] In the fourth invention, in the third invention, In the second cleaning step, second cleaning water having a temperature higher than that of the first cleaning water flowing into the common pipe from the first inlet in the first cleaning step is caused to flow into and be stored in the common pipe, By performing the first cleaning step after the second cleaning step, for a predetermined time from the start of the first cleaning step, the first cleaning water stored in the common pipe in the second cleaning step is injected from a plurality of nozzles This is a cleaning method characterized by the above.
[0025] Thereby, the second cleaning water having a temperature higher than that of the first cleaning water gives heat to the object to be cleaned and the dirt components attached to the object to be cleaned in advance to increase the fluidity of the dirt components, promotes the removal of the dirt components by the first cleaning water, and can improve the cleanability of the object to be cleaned.
[0026] Also, the length of the cleaning time per time can be made as short as possible, and the energy for injecting the cleaning water can be reduced.

[0030] As a result, the total amount of cleaning water jetted from the entire plurality of nozzles can be reduced, and the energy for jetting the cleaning water can be reduced.

[0032] As a result, cleaning water can be stored in the common pipe, and after storage, when cleaning water is made to flow into the common pipe from the first inlet or the second inlet, while reducing the amount of cleaning water flowing in from the first inlet or the second inlet by the amount of cleaning water stored in the common pipe, cleaning water can be quickly jetted from the plurality of nozzles.
[0033] Moreover, the cleaning time for the object to be cleaned per cycle can be made as short as possible, and the energy for injecting the cleaning water can be reduced.
[0034] Also, when the cleaning water is allowed to flow from the first inlet or the second inlet into the common pipe for a predetermined time, compared with the case where the cleaning water is not stored in the common pipe, the cleaning water can be injected for a longer time, and the cleanability of the object to be cleaned can be improved.
[0035] In the seventh invention, in the sixth invention, the cleaning water for cleaning the object to be cleaned by injecting from a plurality of nozzles is the cleaning water flowing from the first inlet into the common pipe is defined as the first cleaning water, the cleaning water flowing from the second inlet into the common pipe is defined as the second cleaning water, after the first cleaning water is allowed to flow from the first inlet into the common pipe and injected from the plurality of nozzles, when the second cleaning water is allowed to flow from the second inlet into the common pipe, the first cleaning water stored in the common pipe is injected from the plurality of nozzles together with the second cleaning water which is characterized as a cleaning device.
[0036] Thereby, when the second cleaning water is allowed to flow from the second inlet and the cleaning water is injected from the plurality of nozzles, the total amount of the cleaning water injected from the first nozzle and the second nozzle is different from that when the first cleaning water is allowed to flow from the first inlet and injected from the plurality of nozzles. By injecting the first cleaning water stored in the common pipe, the total amount of the first cleaning water injected from the first nozzle and the second nozzle can be equalized in one cleaning of the object to be cleaned, and the cleaning degree by the first cleaning water can be equalized among a plurality of objects to be cleaned.
[0037] In the eighth invention, in the seventh invention, the second cleaning water flowing from the second inlet into the common pipe is cleaning water having a higher temperature than the first cleaning water flowing from the first inlet into the common pipe, After causing the second cleaning water to flow from the second inlet into the common pipe and be jetted from the plurality of nozzles, when causing the first cleaning water to flow from the first inlet into the common pipe, the second cleaning water stored in the common pipe is jetted from the plurality of nozzles together with the first cleaning water. It is a cleaning device characterized by this.
[0038] Thereby, the second cleaning water having a temperature higher than that of the first cleaning water gives heat to the object to be cleaned and the dirt components attached to the object to be cleaned in advance to increase the fluidity of the dirt components, and promotes the removal of the dirt components by the first cleaning water, so that the cleanability of the object to be cleaned can be improved.
[0039] In addition, the length of the cleaning time per time can be made as short as possible, and the energy for jetting the cleaning water can be reduced.

[0059] (Cleaning chamber) As shown in FIGS. 2, 4, and 6, the cleaning chamber 30 is a space surrounded by the wall surfaces on the left side, right side, back side, and top side of a housing formed of sheet metal or the like, a partition member 38 on the bottom side, and a door portion 4 provided on the front side. The bottle G to be cleaned is accommodated in the cleaning chamber 30, and the bottle G is cleaned by spraying cleaning water thereon.
[0060] In the cleaning chamber 30, On the front side of the cleaning chamber 30, there is an openable and closable door portion 4 that can communicate the outside of the cleaning device 1 with the cleaning chamber 30 when opened and can make the cleaning chamber 30 in a substantially sealed state when closed, a rack 50 for storing the bottle G to be cleaned, a rack support portion 31 for supporting the rack 50 from below in the cleaning chamber 30, a rotary nozzle 40 that sprays the inflowing cleaning water from above the bottle G from an upper connection opening 32 that allows the cleaning water to flow to the nozzles in the cleaning chamber 30, a nozzle 52 that sprays the cleaning water flowing in from a lower connection opening 35 that allows the cleaning water to flow to the nozzles in the cleaning chamber 30 from below the bottle G through a connection portion 60 to a common pipe 51 fixed to the rack 50, are provided.
[0061] The door portion 4 is configured to be openable and closable at an opening provided on the front side of the cleaning device 1 so as to allow access to the inside of the cleaning chamber 30 when loading and unloading the bottle G into and out of the cleaning chamber 30, and during cleaning and maintenance inside the cleaning chamber 30.
[0062] The rack 50 can accommodate a plurality of bottles G, and is configured to be freely removable between the inside of the cleaning chamber 30 and the outside of the cleaning device 1 with the door portion 4 on the front side of the cleaning chamber 30 open. Thereby, a plurality of bottles G can be loaded into or unloaded from the cleaning chamber 30 at once.
[0063] Inside the wall surfaces on the left and right sides in the cleaning chamber 30, a pair of rack support portions 31 for supporting the rack 50 carried into the cleaning chamber 30 from below are provided, and the rack 50 carried into the cleaning chamber 30 is supported at a predetermined height position in the cleaning chamber 30.
[0064] At the upper and lower parts of the cleaning chamber 30, there are provided an upper connection opening 32 and a lower connection opening 35 for flowing the cleaning water discharged from the cleaning water supply means 13 and 23 into the cleaning chamber 30.
[0065] A rotary nozzle 40 for jetting the cleaning water flowing in from the upper connection opening 32 downward from the upper part of the cleaning chamber 30 is attached to the upper connection opening 32.
[0066] A connection part 60 for flowing the cleaning water to the common pipe 51 fixed to the rack 50 is attached to the lower connection opening 35, and the cleaning water flowing into the common pipe 51 from the lower connection opening 35 through the connection part 60 is jetted upward from a plurality of nozzles 52 attached to the common pipe 51.
[0067] The bottle G stored in the rack 50 is cleaned on the outside and the inside in the cleaning chamber 30 by jetting the cleaning water from the rotary nozzle 40 from above and by jetting the cleaning water from the nozzle 52 of the common pipe 51 from below.
[0068] (Door part) As shown in FIGS. 1, 4, and 6, the door part 4 has a handle 4a attached to the upper front part of the door part 4 for opening and closing the door part 4 by gripping and operating it, and a rack standby part 5 attached to the inner surface of the door part 4 for supporting the rack 50 carried out from the cleaning chamber 30 from below, and a door sensor (sensor) 4b for detecting that the door part 4 is closed, and is provided.
[0069] The door part 4 is configured to be rotatable from a closed state in a substantially vertical direction to a substantially horizontal direction in a fully open state by gripping the handle 4a and pulling it forward. The rack waiting part 5 on the inner surface side (upper surface side) of the door part 4 in the fully open state can place the rack 50 carried out from the cleaning chamber 30. And it serves as a placement table when replacing the objects to be cleaned before and after cleaning stored in the rack 50. (See Fig. 6) Thus, the door part 4 functions not only to seal the cleaning chamber 30 but also as a placement table for the rack 50 carried out from the cleaning chamber 30.
[0070] The rack waiting part 5 is a long member having a horizontal plane formed by sheet metal or the like, and a pair of them are provided facing each other so as to be at substantially the same height position as the rack support part 31 in the cleaning chamber 30 described later when the door part 4 is fully opened. The rack waiting part 5 is configured such that when pulling out and carrying out the rack 50 from the cleaning chamber 30, the rack 50 can be easily transferred from the rack support part 31 in the cleaning chamber 30 to the rack waiting part 5. And the bottles G before and after cleaning can be replaced at the "rack waiting position" where the rack 50 is placed on the rack waiting part 5.
[0071] Inside the side walls on the left side and the right side of the cleaning device 1, at the location where the stay 4c that supports the opening and closing operation of the door part 4 contacts when the door part 4 is closed, a door sensor 4b, which is a limit switch for example, is provided. The door sensor 4b is electrically connected to the control part 6 and is configured to detect that the door part 4 is in the closed state and send a signal to the control part 6. Note that the door sensor 4b is not limited to a limit switch as long as it can detect that the door part 4 is in the closed state, and it may be configured with a proximity switch or the like, or may be provided on only one of the left side and the right side.
[0072] (Rack) As shown in FIGS. 2, 9, and 10, the rack 50 is formed, for example, of resin or the like into a substantially rectangular shape in top view, and the inside is partitioned in a grid pattern to form a plurality of storage spaces 50a. By storing the bottles G in the respective storage spaces 50a, the plurality of bottles G can be arranged at a predetermined interval in the horizontal direction. Then, a plurality of bottles G can be carried into the cleaning chamber 30 at once for cleaning and also carried out from the cleaning chamber 30.
[0073] At the bottom of the rack 50, there is provided a common pipe 51 having nozzles 52 for flowing two types of cleaning water arranged in the horizontal direction and injecting the flowing cleaning water. A plurality of nozzles 52 having a predetermined length and having injection ports 52a for injecting the cleaning water upward are provided upward so as to be arranged in the respective storage spaces 50a. Then, with the opening G1 of the bottle G facing downward in an inverted posture, the nozzles 52 are inserted into the bottle G from the opening G1 into the interior of the bottle G, and the bottle G is stored in the storage space 50a of the rack 50.
[0074] Note that the lengths, inner diameters of the nozzles 52, and the diameters of the injection ports 52a are configured to be substantially the same in the plurality of nozzles 52.
[0075] At the lower end portions of both side surfaces of the rack 50, sliding members 50b formed of resin or the like along both side surfaces of the rack 50 are provided. When the rack 50 is carried into the cleaning chamber 30, the rack 50 is supported from below by the rack support portion 31 via the sliding members 50b. Thereby, the sliding resistance when carrying the rack 50 having increased weight by storing the bottle G into and out of the cleaning chamber 30 can be reduced.
[0076] (Rack support portion) As shown in FIGS. 2 and 4, the rack support portion 31 is a long member having a horizontal plane formed of sheet metal or the like, and a pair of them are provided opposite to each other at a predetermined height position inside the wall surfaces of the left and right side surfaces in the cleaning chamber 30.
[0077] The rack support portion 31 supports the rack 50 from below via sliding members 50b formed of resin or the like provided at the lower end portions on both side surfaces of the rack 50. Thereby, the rack 50 is supported at a predetermined height position in the washing chamber 30, and when the rack 50 is carried in and out, it can slide smoothly on the rack support portion 31. Then, the rack 50 storing the bottles G and having an increased weight can be smoothly carried in and out of the washing chamber 30.
[0078] Note that the rack support portion 31 is not particularly limited as long as it can make the rack 50 slidable. For example, it may be configured by a resin plate or rollers instead of sheet metal.
[0079] (Connection opening) As shown in FIG. 2, the connection openings 32 and 35 are connected to the first washing water supply means 13 and the second washing water supply means 23 by the first washing pipe 14 and the second washing pipe 24, and are formed by a double pipe in which large-diameter pipes 33 and 36 that are the ends of the flow paths of the first washing pipe 14 are combined outside small-diameter pipes 34 and 37 that are the ends of the flow paths of the second washing pipe 24. That is, the connection openings 32 and 35 are members that gather the ends of the flow paths of the first washing pipe 14 and the second washing pipe 24. The washing chamber 30 is provided with two connection openings. An upper connection opening 32 is provided at the upper part of the substantially central portion in the horizontal direction of the washing chamber 30, and a lower connection opening 35 is provided at the lower part of the substantially central portion in the horizontal direction of the washing chamber 30 so as to face each other in the vertical direction. Hereinafter, the specific configuration of the connection openings 32 and 35 will be described taking the lower connection opening 35 as an example.
[0080] As shown in FIG. 16, in the lower connection opening 35, the pipe between the inner surface of the large-diameter pipe 36 and the outer surface of the small-diameter pipe 37 forms a first flow path (flow path) 36a through which the first washing water W1 can flow from the first washing pipe 14, and the pipe of the small-diameter pipe 37 forms a second flow path (flow path) 37a through which the second washing water W2 can flow from the second washing pipe 24.
[0081] The end face of the small-diameter pipe 37 protrudes from the end face of the large-diameter pipe 36, and a threaded portion 37b is formed at the tip. By inserting a connection portion 60 (described later) into the protruding portion of the small-diameter pipe 37 via a plurality of bearing portions (not numbered) and attaching a cap 35a to the threaded portion 37b, it can be rotatably and detachably attached to the lower connection opening 35.
[0082] On the tip side of the small-diameter pipe 37, a hole 37c is formed in the wall surface. By attaching a cap 35a to the threaded portion 37b at the tip of the small-diameter pipe 37, the tip is closed, but the second cleaning water W2 flowing through the second flow path 37a can flow out from the hole 37c in the wall surface.
[0083] The large-diameter pipe 36 has an opening at the tip, and is configured such that the first cleaning water W1 flowing through the first flow path 36a can flow out from the opening at the tip.
[0084] The upper connection opening 32 has a structure that is the reverse of the lower connection opening 35 in the vertical direction, and a specific description is omitted.
[0085] Details will be described later, but the joint portions 42, 44 of the rotary nozzle 40 are attached to the upper connection opening 32, and the joint portions 61, 63 of the connection portion 60 connected to the common pipe 51 of the rack 50 are attached to the lower connection opening 35.
[0086] (Rotary Nozzle) As shown in FIGS. 4, 5, and 8, the rotary nozzle 40 is composed of a first cleaning nozzle (rotary nozzle) 41 and a second cleaning nozzle (rotary nozzle) 43.
[0087] The first cleaning nozzle 41 is a nozzle formed in a long hollow shape and flattened in the vertical direction, and has a flow path for flowing the first cleaning water W1 inside. On the lower surface, a plurality of injection ports 41a for injecting cleaning water downward are provided.
[0088] At approximately the center in the longitudinal direction of the first cleaning nozzle 41, there is provided a first joint portion (joint portion) 42 that is rotatably connected to the small-diameter pipe 34 of the upper connection opening 32. Inside the first joint portion 42, there is a flow path that communicates with the inside of the first cleaning nozzle 41. By attaching the rotary nozzle 40 to the upper connection opening 32, the first joint portion 42 is arranged so as to cover the opening of the end face of the large-diameter pipe 33 of the upper connection opening 32, and the first flow path (flow path) 33a of the upper connection opening 32 and the flow path inside the first cleaning nozzle 41 communicate with each other via the first joint portion 42.
[0089] The second cleaning nozzle 43 is a long, round pipe-shaped nozzle with both ends closed, and has a flow path inside through which the second cleaning water W2 flows. A plurality of injection ports 43a are provided at the apex of the lower surface.
[0090] At approximately the center in the longitudinal direction of the second cleaning nozzle 43, there is provided a second joint portion (joint portion) 44 that is rotatably connected to the protruding portion of the small-diameter pipe 34 of the upper connection opening 32. Inside the second joint portion 44, there is a flow path that communicates with the inside of the second cleaning nozzle 43. By attaching the rotary nozzle 40 to the upper connection opening 32, the second joint portion 44 is arranged so as to cover the hole 37c in the wall surface on the tip side of the small-diameter pipe 34, and the second flow path (flow path) 34a of the upper connection opening 32 and the flow path inside the second cleaning nozzle 43 communicate with each other via the second joint portion 44.
[0091] The first cleaning nozzle 41 and the second cleaning nozzle 43 are integrally coupled by bolts or the like with a predetermined angle, for example, 25 degrees to 26 degrees, in the rotational direction around the approximate center. The first joint portion 42 and the second joint portion 44 have a plurality of bearing portions (not shown) so as to be rotatable with respect to the small-diameter pipe 34 of the upper connection opening 32. By inserting the rotary nozzle 40 into the small-diameter pipe 34 of the upper connection opening 32 and attaching the cap 32a, it can be rotatably attached to the upper connection opening 32.
[0092] When the rotary nozzle 40 is attached to the upper connection opening 32, the first flow path 33a of the upper connection opening 32 communicates with the flow path of the first joint portion 42, and the first cleaning water W1 can flow to the first cleaning nozzle 41. Similarly, the second flow path 34a of the upper connection opening 32 communicates with the flow path of the second joint portion 44, and the second cleaning water W2 can flow to the second cleaning nozzle 43. In this way, the first cleaning water W1 and the second cleaning water W2 can be made to flow to the rotary nozzle 40 through separate flow paths respectively.
[0093] At both ends of each of the first cleaning nozzle 41 and the second cleaning nozzle 43, injection ports for rotation (not shown) are provided, and the rotary nozzles 41 and 43 are configured to be rotated by the injection pressure of the cleaning water injected from the injection ports for rotation. Thereby, the first cleaning water W1 and the second cleaning water W2 can be evenly injected onto a plurality of bottles G stored in the rack 50.
[0094] (Common pipe) As shown in FIGS. 9 and 10, the common pipe 51 is formed in a comb shape in top view with its pipe path bent and branched in a substantially horizontal direction, and a plurality of nozzles 52 provided so as to extend upward from the common pipe 51 are fixed to the bottom of the rack 50 so as to be arranged substantially at the center in top view within each storage space 50a, forming one continuous pipe path from one end side to the other end side.
[0095] A first inlet (inlet) 53 for allowing the first cleaning water W1 to flow in is provided at one end side of the common pipe 51. A first connection pipe (connection pipe) 62 connected to a connection portion 60 described later is connected to the first inlet 53 via a first check valve (check valve) 53a. The first check valve 53a is attached so that the cleaning water in the common pipe 51 does not flow back from the common pipe 51 to the first connection pipe 62.
[0096] On the other end side of the common pipe 51, a second inlet (inlet) 55 for allowing the second washing water W2 to flow in is provided. A second connection pipe (connection pipe) 64 connected to the connection part 60 is connected to the second inlet 55 via a second check valve (check valve) 55a. The second check valve 55a is attached so that the washing water in the common pipe 51 does not flow backward from the common pipe 51 into the second connection pipe 64. By configuring the common pipe 51 in this way, the following flow path is formed.
[0097] As shown in FIG. 11, when the first washing water W1 flows in from the first inlet 53, since the second check valve 55a is in a closed state, the common pipe 51 forms a first flow path (flow path) 54 which is a continuous single flow path with the end of the pipe blocked.
[0098] Conversely, as shown in FIG. 12, when the second washing water W2 flows in from the second inlet 55, since the first check valve 53a is in a closed state, the common pipe 51 forms a second flow path (flow path) 56 which is a continuous single flow path with the end of the pipe blocked.
[0099] Also, when washing water does not flow into the common pipe 51 from either inlet 53, 55, that is, when both the washing water supply means 13, 23 are stopped and no discharge pressure is applied from the washing water supply means 13, 23, both the first check valve 53a and the second check valve 55a are in a closed state, so that the washing water that last flowed into the common pipe 51 can be stored.
[0100] Thereby, it is possible to prevent the washing water in the common pipe 51 from flowing backward from the inlets 53, 55 and different washing waters from mixing in the washing water supply means 13, 23 and the tanks 10, 20, and it is possible to store the washing water in the common pipe 51.
[0101] Also, in the common pipe 51, since the positions where the first inlet 53 and the second inlet 55 are provided are different, the pipe lengths (flow path lengths) from the inlets 53, 55 to each nozzle 52 are different in the first flow path 54 and the second flow path 56.
[0102] For example, among the plurality of nozzles 52 of the rack 50, the nozzle 52 at the position with the shortest flow path length from the first inlet 53 (the nozzle 52 closest to the first inlet 53) is defined as the first nozzle (nozzle) 52X at the X position, and the nozzle 52 at the position with the shortest flow path length from the second inlet 55 (the nozzle 52 closest to the second inlet 55) is defined as the second nozzle (nozzle) 52Y at the Y position. This will be described below.
[0103] As shown in FIG. 11, in the first flow path 54, the flow path length from the first inlet 53 to the second nozzle 52Y at the Y position is longer than the flow path length from the first inlet 53 to the first nozzle 52X at the X position. That is, the second nozzle 52Y at the Y position is located at a position farther than the distance between the first nozzle 52X at the X position, which is the closest position to the first inlet 53, with respect to the first inlet 53.
[0104] Also, as shown in FIG. 12, in the second flow path 56, the flow path length from the second inlet 55 to the first nozzle 52X at the X position is longer than the flow path length from the second inlet 55 to the second nozzle 52Y at the Y position. That is, the first nozzle 52X at the X position is located at a position farther than the distance between the second nozzle 52Y at the Y position, which is the closest position to the second inlet 55, with respect to the second inlet 55. Thus, by providing the inlets 53 and 55 at different locations of the common pipe 51, the flow path lengths to the respective nozzles 52 with respect to the inlets 53 and 55 are configured to be different.
[0105] Note that the plurality of nozzles 52 may include a nozzle 52 having the same flow path length from the first inlet 53 and the second inlet 55 in the first flow path 54 and the second flow path 56, and at least two or more nozzles 52 may be configured such that their flow path lengths are different.
[0106] Also, the positions of the first inlet 53 and the second inlet 55 are not limited to one end side and the other end side of the common pipe 51, and may be different positions. However, as will be described later, for example, when comparing the total amounts of the cleaning waters W1 and W2 jetted from the first nozzle 52X at the X position and the second nozzle 52Y at the Y position, the first flow path 54 and the second flow path 56 are arranged such that the amounts of the total cleaning waters W1 and W2 jetted are substantially reversed. It is preferable to provide the first inlet 53 and the second inlet 55 at one end side and the other end side of the common pipe 51 that are as far apart from each other as possible (distant positions).
[0107] As shown in FIGS. 2 and 10, a plurality of nozzles 52 for jetting the cleaning waters W1 and W2 flowing in the common pipe 51 are provided upward in the common pipe 51.
[0108] The nozzle 52 is a hollow pipe formed with a predetermined length, has an injection port 52a on the upper surface of the upper end portion, and the lower end portion is attached to a hole provided in the upper portion of the horizontally formed common pipe 51 by welding or the like, and is configured such that the inside of the nozzle 52 communicates with the inside of the common pipe 51. Thereby, the cleaning waters W1 and W2 flowing in the common pipe 51 flow upward in the nozzle 52 and can be jetted upward from the injection port 52a.
[0109] The plurality of nozzles 52 provided in the common pipe 51 are attached to the common pipe 51 so as to be respectively arranged substantially at the center in a top view of the storage space 50a of the rack 50 when the common pipe 51 is arranged at the bottom of the rack 50.
[0110] Note that the lengths, inner diameters of the nozzles 52, and the diameters of the injection ports 52a are configured to be substantially the same in the plurality of nozzles 52.
[0111] As shown in FIGS. 2 and 13, a spacer 57 formed in an annular shape by resin or the like is detachably provided near the base of the nozzle 52 provided in the common pipe 51 (near the joint between the common pipe 51 and the nozzle 52). With the opening G1 of the bottle G facing downward in an inverted posture, when the nozzle 52 is inserted into the bottle G from the opening G1 and the bottle G is stored in the storage space 50a of the rack 50, the opening G1 of the bottle G is placed on the upper surface of the spacer 57. Thereby, it is possible to prevent the bottle G formed of, for example, glass from being damaged by vibration or the like caused by the injection of washing water.
[0112] The spacer 57 is provided with a notch 57a penetrating the spacer 57 in the vertical direction, so that the washing water jetted from the nozzle 52 into the bottle G can flow down the inner surface of the bottle G and flow out from the opening G1 of the bottle G through the notch 57a. Note that the notch 57a does not necessarily penetrate the spacer 57 in the vertical direction, and may have a notch 57a extending from the upper surface to the side surface, for example, as long as the washing water in the bottle G can flow out. The amount of washing water flowing out from the opening G1 of the bottle G per unit time can be adjusted by the size of the area of the notch 57a.
[0113] The shape of the spacer 57 is not limited to an annular shape, and may be other shapes such as a rectangular shape. Also, the shape including the notch 57a is not limited to a C-shaped view from above, and may be other shapes such as a polygonal shape or a petal shape in a top view. In this case, it is preferable to maintain a state in which the opening G1 of the bottle G can be stably placed and set the size and shape of the opening of the notch 57a.
[0114] Also, by changing the thickness of the spacer 57, the position of the bottle G in the height direction with respect to the position of the injection port 52a of the nozzle 52 can be changed. For example, when cleaning bottles G with different height positions of the neck G4 of the bottle G, such as storing and cleaning a plurality of bottles G with different shapes together in the rack 50, by using spacers 57 with different thicknesses, the height position of the shoulder G3 of the bottle G with respect to the injection port 52a can be adjusted to a desired position without changing the height of the nozzle 52.
[0115] Thereby, when the washing water injected into the bottle G temporarily stays near the neck G4 until it flows out from the notch portion 57a, it is possible to prevent the injection port 52a from being submerged in the retained washing water and the washing water injected from the injection port 52a from not being injected to a desired position inside the bottle G.
[0116] Also, for example, when it is desired to concentrate and inject the washing water toward a portion where dirt is likely to accumulate, such as the bottom surface inside the bottle G, the thickness of the spacer 57 may be changed to adjust the position of the injection port 52a in the height direction of the bottle G so that the washing water comes into good contact with the bottom surface of the bottle G. Thereby, optimal cleaning can be performed according to the shape of the bottle G and the location where dirt has accumulated.
[0117] Note that the pipeline shape (piping layout) of the common pipe 51 is an example, and any pipeline shape may be used as long as a plurality of nozzles 52 can be arranged in each storage space 50a. For example, the pipeline shape of the common pipe can also be a loop pipe having a substantially rectangular shape in top view without an end. Also in this case, the positions of the first inlet 53 and the second inlet 55 may be provided at different positions of the loop pipe, and it is preferable to provide them, for example, at diagonal positions or opposite side positions in top view so as to be as far apart from each other as possible.
[0118] (Connection part) As shown in FIGS. 2, 14, 15, and 16, the connection portion 60 is rotatably and detachably connected to the lower connection opening 35, and constitutes a flow path for flowing the cleaning water from the lower connection opening 35 to the common pipe 51 of the rack 50.
[0119] The connection portion 60 is connected to the first inlet 53 of the common pipe 51 via the first check valve 53a, and a first connection pipe 62 for flowing the first cleaning water W1; connected to the second inlet 55 of the common pipe 51 via the second check valve 55a, and a second connection pipe 64 for flowing the second cleaning water W2; a first joint portion (joint portion) 61 for flowing the first cleaning water W1 from the first flow path 36a of the lower connection opening 35 to the first connection pipe 62; a second joint portion (joint portion) 63 for flowing the second cleaning water W2 from the second flow path 37a of the lower connection opening 35 to the second connection pipe 64; and includes.
[0120] Note that FIG. 16 is shown in a state where the D-D cross section and the E-E cross section of FIG. 14 are combined in consideration of the visibility of the drawing.
[0121] The first connection pipe 62 and the second connection pipe 64 are, for example, rubber hoses formed of a deformable material, and are configured to be deformable so as to follow the movement of the rack 50 when the rack 50 is taken in and out of the cleaning chamber 30.
[0122] Inside the first joint portion 61, there is a flow path that communicates the first flow path 36a and the first connection pipe 62. By attaching the connection portion 60 to the lower connection opening 35, the first joint portion 61 is arranged to cover the opening of the end face of the large-diameter pipe 36 of the lower connection opening 35, and the first flow path 36a of the lower connection opening 35 and the first connection pipe 62 communicate with each other via the first joint portion 61.
[0123] Inside the second joint portion 63, there is a flow path that communicates the second flow path 37a and the second connection pipe 64. By attaching the connection portion 60 to the lower connection opening 35, the second joint portion 63 is arranged to cover the hole 37c in the wall surface on the tip side of the small-diameter pipe 37, and the second flow path 37a of the lower connection opening 35 and the second connection pipe 64 communicate with each other via the second joint portion 63.
[0124] The first joint portion 61 and the second joint portion 63 are integrally coupled in the vertical direction by bolts or the like, and have a bearing portion (not shown) so as to be rotatable with respect to the small-diameter pipe 37 of the lower connection opening 35. The connection portion 60 can be rotatably attached to the lower connection opening 35 by inserting it into the small-diameter pipe 37 of the lower connection opening 35 and attaching the cap 35a. In this way, the connection portion 60 is a member that gathers the ends of the connection pipes 62 and 64 through which the cleaning waters W1 and W2 flow from the lower connection opening 35 to the common pipe 51 of the rack 50, and acts to transfer the cleaning waters W1 and W2 flowing from the lower connection opening 35 to the common pipe 51.
[0125] When the connection portion 60 is attached to the lower connection opening 35, the first flow path 36a of the lower connection opening 35 and the flow path of the first joint portion 61 communicate with each other, and the first cleaning water W1 can flow into the first connection pipe 62. Then, the first cleaning water W1 can be made to flow from the first connection pipe 62 to the first inlet 53. Similarly, the second flow path 37a of the lower connection opening 35 and the flow path of the second joint portion 63 communicate with each other, and the second cleaning water W2 can flow into the second connection pipe 64. Then, the second cleaning water W2 can be made to flow from the second connection pipe 64 to the second inlet 55. In this way, the first cleaning water W1 and the second cleaning water W2 can be made to flow into the common pipe 51 of the rack 50 through different flow paths.
[0126] By attaching the connection part 60 to the lower connection opening 35, while suppressing the leakage of the cleaning water, when carrying the rack 50 into or out of the cleaning chamber 30, the connection part 60 rotates in accordance with the movement of the rack 50 and the connection pipes 62, 64 are deformed so as to follow, and the loading and unloading of the rack 50 can be performed more smoothly. (See FIGS. 4 and 6)
[0127] Also, since the connection part 60 is configured to be detachably connected to the lower connection opening 35, for example, when cleaning bottles G having different shapes (such as height), when replacing the storage space 50a and the rack 50 provided with the nozzles 52 (for example, nozzles having different heights) according to the shape of the bottle G, by simply removing the cap 35a of the lower connection opening 35, the connection part 60, the connection pipes 62, 64, the common pipe 51, and the entire set of the rack 50 can be removed at once.
[0128] Thereby, when cleaning bottles G having different shapes, the replacement work for the rack 50 and the nozzles 52 according to the shape of the bottle G is facilitated, and cleaning suitable for the shapes of different objects to be cleaned can be performed to improve the cleaning power.
[0129] (The first tank and the first cleaning water supply means) As shown in FIG. 2, the first tank 10 stores the first cleaning water W1 and receives the cleaning water sprayed from the rotary nozzle 40 and the nozzle 52 of the rack 50 in the cleaning chamber 30, and stores it as the first cleaning water W1. Further, the first tank 10 is connected by a pipe to the suction port of the first cleaning water supply means 13 which is a pump or the like. The discharge port of the first cleaning water supply means 13 is connected to the upper connection opening 32 and the lower connection opening 35 by the first cleaning pipe 14. The first cleaning water supply means 13 is electrically connected to the control unit 6.
[0130] The first tank 10 is the first heating means (heating means) 11 for heating the first cleaning water W1 stored in the first tank 10, the first temperature sensor (sensor) 12 for detecting the temperature of the first cleaning water W1, An upper limit water level sensor (sensor) 17a for detecting the upper limit water level of the first washing water W1, A lower limit water level sensor (sensor) 17b for detecting the lower limit water level of the first washing water W1, A drain port 15 provided at the bottom for draining the first washing water W1 stored in the first tank 10, An overflow and drain plug 16 detachably connected to the drain port 15 for overflowing the first washing water W1 exceeding a predetermined water level and guiding it to the drain port 15, are provided.
[0131] The first heating means 11 is, for example, an electric heater electrically connected to the control unit 6, and heats and maintains the first washing water W1 stored in the first tank 10 at a predetermined temperature, for example, 60 degrees C.
[0132] The first temperature sensor 12 is electrically connected to the control unit 6 and is configured to detect the temperature of the first washing water W1 and send a signal to the control unit 6. When the first temperature sensor 12 detects that the first washing water W1 is lower than a predetermined temperature, for example, 60 degrees C, the control unit 6 operates the first heating means 11 to heat the first washing water W1 until it reaches the predetermined temperature. Further, when the first temperature sensor 12 detects that the first washing water W1 has exceeded the predetermined temperature, the control unit 6 stops the operation of the first heating means 11 and controls to maintain the first washing water W1 at the predetermined temperature.
[0133] The upper limit water level sensor 17a is electrically connected to the control unit 6 and is, for example, an electrode type sensor provided at the water level where the first tank 10 is full, and is configured to detect that the first washing water W1 stored in the first tank 10 is full and send a signal to the control unit 6.
[0134] The lower water level sensor 17b is, for example, an electrode type sensor provided at the lower limit water level of the first tank 10, and is provided at a position slightly higher than the first heating means 11 in the first tank 10. When the control unit 6 detects that the water level of the first washing water W1 is lower than the lower limit water level, the control unit 6 stops the first heating means 11. Thereby, dry burning of the first heating means 11 can be prevented.
[0135] A drain pipe 15a that enables drainage to the drainage facility in the facility is provided at the drain port 15 provided at the bottom of the first tank 10.
[0136] The overflow and drain plug 16 has its lower end side detachably connected to the drain port 15, and its upper end is disposed at a position slightly higher than the full water level of the first washing water W1. Then, the first washing water W1 that has become higher than the full water level overflows into the overflow and drain plug 16 from the opening provided at the upper end of the overflow and drain plug 16, and is drained from the drain pipe 15a through the drain port 15. In this way, the first washing water W1 is not stored in the first tank 10 beyond the upper end of the overflow and drain plug 16.
[0137] Also, during cleaning or the like, by removing the overflow and drain plug 16 from the drain port 15, the first washing water W1 stored in the first tank 10 can be directly drained from the drain pipe 15a through the drain port 15.
[0138] (Second Tank and Second Washing Water Supply Means) As shown in FIG. 2, the second tank 20 stores the second washing water W2 which is clean water. The second tank 20 is connected to the suction port of the second washing water supply means 23 which is a pump or the like by a pipe, and the discharge port of the second washing water supply means 23 is connected to the upper connection opening 32 and the lower connection opening 35 by the second washing pipe 24. The second washing water supply means 23 is electrically connected to the control unit 6.
[0139] The second tank 20 A water supply pipe 28 connected to a water supply such as a water pipe in a facility where the cleaning device 1 is installed, A second heating means (heating means) 21 for heating the second cleaning water W2 stored in the second tank 20, A second temperature sensor (sensor) 22 for detecting the temperature of the second cleaning water W2, An upper limit water level sensor (sensor) 27a for detecting the upper limit water level of the second cleaning water W2, A lower limit water level sensor (sensor) 27b for detecting the lower limit water level of the second cleaning water W2, A drain port 25 provided at the bottom for draining the second cleaning water W2 stored in the second tank 20, An overflow pipe 26 for overflowing and draining the second cleaning water W2 that exceeds a predetermined water level, is provided.
[0140] The water supply pipe 28 is provided with a solenoid valve 28a electrically connected to the control unit 6. The control unit 6 opens the solenoid valve 28a until it is detected by the upper limit water level sensor 27a that the tank is full, and controls to supply the second cleaning water W2, which is clean water, to the second tank 20. Further, when the upper limit water level sensor 27a detects that the tank is full, the control unit 6 closes the solenoid valve 28a and controls to stop the water supply.
[0141] The second heating means 21 is, for example, an electric heater electrically connected to the control unit 6, and heats and maintains the second cleaning water W2 stored in the second tank 20 at a predetermined temperature, for example, 80 degrees Celsius.
[0142] The second temperature sensor 22 is electrically connected to the control unit 6, and is configured to detect the temperature of the second cleaning water W2 and send a signal to the control unit 6. When the second temperature sensor 22 detects that the second cleaning water W2 is lower than a predetermined temperature, for example, 80 degrees Celsius, the control unit 6 operates the second heating means 21 to heat the second cleaning water W2 until it reaches the predetermined temperature. Further, when the second temperature sensor 22 detects that the second cleaning water W2 has reached the predetermined temperature, the control unit 6 stops the operation of the second heating means 21 and controls to maintain the second cleaning water W2 at the predetermined temperature.
[0143] The upper limit water level sensor 27a is electrically connected to the control unit 6, and is, for example, a float type water level sensor provided at the water level where the second tank 20 is full. It is configured to detect that the second washing water W2 stored in the second tank 20 is full and send a signal to the control unit 6.
[0144] The lower limit water level sensor 27b is, for example, a float type water level sensor provided at the lower limit water level of the second tank 20, and is provided at a position slightly higher than the second heating means 21 in the second tank 20. When it detects that the water level of the second washing water W2 is lower than the lower limit water level, the control unit 6 stops the operation of the second heating means 21. Thereby, dry burning of the second heating means 21 can be prevented.
[0145] A drain pipe 25a that can drain to the drainage facility in the facility is attached to the drain port 25 provided at the bottom of the second tank 20. A detachable drain cap 25b is attached to the end side of the drain pipe 25a. When draining the second washing water W2 in the second tank 20, it can be drained by removing the drain cap 25b. Note that instead of the drain cap 25b, an on - off valve such as a manual on - off valve or a solenoid valve may be provided so that the on - off valve can be operated to drain the water.
[0146] An overflow pipe 26 is connected to a position slightly higher than the upper limit water level at which the second tank 20 is full. When the amount of water supplied exceeds the upper limit water level, it overflows into the overflow pipe 26 and is drained to the drainage facility in the facility.
[0147] Note that although the first heating means 11 and the second heating means 21 have been described as electric heaters, they may be, for example, gas combustion type heaters, and can be appropriately selected according to the facilities of the facility where the cleaning device 1 is installed.
[0148] Incidentally, although the case where both the first cleaning water supply means 13 and the second cleaning water supply means 23 are pumps or the like has been described as an example, either one or both of them may be directly connected to a water supply according to the object to be cleaned and the dirt to be cleaned. In this case, the water outlet of the water supply can be directly connected to the first cleaning pipe 14 or the second cleaning pipe 24 without passing through the tank, and the cleaning water can be supplied by the water supply pressure of the water supply. Thereby, the cleaning device 1 can be miniaturized.
[0149] (Partition member) As shown in FIG. 7, the partition member 38 is detachably placed on the upper surface of the first tank 10, and is composed of a cover member 38a that closes the central portion of the upper surface of the first tank 10 and filter members 38b that close the openings on both sides of the cover member 38a. The filter member 38b is formed of a punching plate or the like having a plurality of holes. The cleaning water sprayed in the cleaning chamber 30 flows down through the plurality of holes of the filter member 38b into the first tank 10 and is stored therein. At this time, dirt larger than the holes of the filter member 38b, such as solids mixed in the cleaning water, is collected by the filter member 38b. Thereby, it is possible to suppress a decrease in the cleanliness of the first cleaning water W1 stored in the first tank 10.
[0150] Also, at the time of cleaning or the like, by removing the filter member 38b from the cleaning chamber 30, solids larger than the holes of the filter member 38b collected by the filter member 38b can be easily removed with a broom or the like. Further, by removing the cover member 38a in addition to the filter member 38b, it becomes possible to access the inside of the first tank 10, and the inside of the first tank 10 can be easily cleaned.
[0151] Incidentally, although the partition member 38 in FIGS. 2, 4, 6, and 17 to 22 is described as being separated from the first tank 10, in reality, it is placed on and in contact with the first tank 10. This is a convenient expression for indicating that the partition member 38 is a member different from the first tank 10.
[0152] (Cleaning water flow system) The cleaning water flow system is a path through which cleaning water flows from tanks 10 and 20 to the rotating nozzle 40 and the nozzle 52 of the rack 50, and includes a first cleaning water flow system 71 through which the first cleaning water W1 flows and a second cleaning water flow system 72 through which the second cleaning water W2 flows.
[0153] (First cleaning water flow system) As shown in FIGS. 5, 16, and 17, the first cleaning water flow system 71 continues from the first tank 10 to the first cleaning water supply means 13 and the first cleaning pipe 14 in sequence, and branches into an upper connection opening 32 side and a lower connection opening 35 side in the middle of the first cleaning pipe 14.
[0154] The path branched to the upper connection opening 32 continues to the first flow path 33a of the upper connection opening 32, the first joint portion 42 of the rotating nozzle 40, and the first cleaning nozzle 41 in sequence. Also, the path branched to the lower connection opening 35 continues to the first flow path 36a of the lower connection opening 35, the first joint portion 61 of the connection portion 60, the first connection pipe 62, the first check valve 53a, and the first inlet 53 and the common pipe 51 in sequence.
[0155] Then, the first cleaning water W1 flowing through the first cleaning water flow system 71 is sucked from the first tank 10 by the first cleaning water supply means 13 and discharged into the first cleaning pipe 14, and branches into an upper connection opening 32 side and a lower connection opening 35 side and flows in the middle of the first cleaning pipe 14.
[0156] The first cleaning water W1 that branches and flows to the upper connection opening 32 side flows into the first cleaning nozzle 41 through the first flow path 33a and the flow path of the first joint portion 42, and is ejected from the ejection port 41a.
[0157] Also, the first cleaning water W1 that branches and flows to the lower connection opening 35 side flows into the first connection pipe 62 through the first flow path 36a and the first joint portion 61. Further, it flows into the common pipe 51 from the first inlet 53 through the first check valve 53a from the first connection pipe 62.
[0158] The first cleaning water W1 that has flowed into the common pipe 51 flows through the first flow path 54 while bending or branching from the first inlet 53 toward the second inlet 55 side, and is ejected from the ejection port 52a of the nozzle 52.
[0159] (Second cleaning water flow system) As shown in FIGS. 5, 16, and 17, the second cleaning water flow system 72 continues from the second tank 20 to the second cleaning water supply means 23 and then to the second cleaning pipe 24, and branches in the middle of the second cleaning pipe 24 into an upper connection opening 32 side and a lower connection opening 35 side.
[0160] The path branched to the upper connection opening 32 continues in order to the second flow path 34a of the upper connection opening 32, the second joint portion 44 of the rotary nozzle 40, and the second cleaning nozzle 43. Also, the path branched to the lower connection opening 35 continues in order to the second flow path 37a of the lower connection opening 35, the second joint portion 63 of the connection portion 60, the second connection pipe 64, the second check valve 55a, the second inlet 55, and the common pipe 51.
[0161] Then, the second cleaning water W2 flowing through the second cleaning water flow system 72 is sucked from the second tank 20 by the second cleaning water supply means 23 and discharged into the second cleaning pipe 24, and branches and flows into an upper connection opening 32 side and a lower connection opening 35 side in the middle of the second cleaning pipe 24.
[0162] The second cleaning water W2 that branches and flows toward the upper connection opening 32 side flows into the second cleaning nozzle 43 through the second flow path 37a and the flow path of the second joint portion 44, and is ejected from the ejection port 43a.
[0163] Also, the second cleaning water W2 that branches and flows toward the lower connection opening 35 side flows from the second flow path 37a through the second joint portion 63 into the second connection pipe 64. Further, it flows from the second connection pipe 64 into the common pipe 51 through the second check valve 55a from the second inlet 55.
[0164] The second cleaning water W2 that has flowed into the common pipe 51 flows through the second flow path 56 while bending or branching from the second inlet 55 toward the first inlet 53 side, and is ejected from the ejection port 52a of the nozzle 52.
[0165] (Control unit) As shown in FIG. 2, the control unit 6 is disposed in the lower outer housing 3 of the cleaning device 1 and is electrically connected to the operation unit 7, the first cleaning water supply means 13, the second cleaning water supply means 23, the first temperature sensor 12, the second temperature sensor 22, the upper limit water level sensors 17a, 27a, the lower limit water level sensors 17b, 27b, the door sensor 4b, the solenoid valve 28a, the first heating means 11, and the second heating means 21. It receives signals from these members and controls the operation of the members according to a pre-programmed program.
[0166] (Cleaning method using the cleaning device) Next, the cleaning method using the cleaning device 1 of the present embodiment will be described with reference to FIGS. 18 to 22.
[0167] In the cleaning method using the cleaning device 1, a preparation step S1 of storing cleaning water at a predetermined temperature in the first tank 10 and the second tank 20 of the cleaning device 1 to make the bottle G, which is the object to be cleaned, in a state where it can be cleaned; after the preparation step S1, a loading step S2 of storing the bottle G in the rack 50 and loading the rack 50 into the cleaning chamber 30 of the cleaning device 1; after the loading step S2, a first cleaning step (cleaning step) S3 of ejecting the first cleaning water W1 to clean the bottle G; after the first cleaning step S3, a second cleaning step (cleaning step) S4 of ejecting the second cleaning water W2 to clean the bottle G; after the second cleaning step S4, an unloading step S5 of unloading the rack 50 in which the bottle G is stored from the cleaning chamber 30; are performed.
[0168] (Preparation step) The preparation step S1 will be specifically described with reference to FIGS. 18 to 20.
[0169] As shown in FIG. 18, first, check that the door portion 4 is closed and turn on the power switch of the operation unit 7. The door sensor 4b detects that the door portion 4 is closed and sends a signal to the control unit 6. The control unit 6 opens the electromagnetic valve 28a provided in the water supply pipe 28 and starts supplying clean water, which is the second cleaning water W2, from the water supply pipe 28 to the second tank 20.
[0170] When the second cleaning water W2 reaches the full water level, the upper limit water level sensor 27a and the lower limit water level sensor 27b detect the full water level and send a signal to the control unit 6. The control unit 6 closes the electromagnetic valve 28a of the water supply pipe 28 to stop the supply of clean water, activates the second heating means 21, and starts heating the second cleaning water W2. The second temperature sensor 22 detects that the second cleaning water W2 stored in the second tank 20 has reached a predetermined temperature, for example, 80 degrees C, and sends a signal to the control unit 6. The control unit 6 stops the second heating means 21.
[0171] Next, as shown in FIG. 19, the control unit 6 drives the second cleaning water supply means 23. Then, the second cleaning water W2 flows through the second cleaning water flow system 72 and is sprayed into the cleaning chamber 30 from the second cleaning nozzle 43 of the rotary nozzle 40 and the nozzle 52 of the rack 50 for a predetermined time, for example, 12 seconds.
[0172] Specifically, the second cleaning water W2 sucked from the second tank 20 by the second cleaning water supply means 23 and discharged into the second cleaning pipe 24 branches from the second cleaning pipe 24 to the upper connection opening 32 and the lower connection opening 35 and flows into the respective second flow paths 34a, 37a.
[0173] The second cleaning water W2 flowing into the second flow path 34a of the upper connection opening 32 flows into the second cleaning nozzle 43 of the rotary nozzle 40 through the second joint portion 44 and is sprayed downward from the spray port 43a.
[0174] The second cleaning water W2 that has flowed into the second flow path 37a of the lower connection opening 35 flows into the second connection pipe 64 through the second joint portion 63, passes through the second check valve 55a, and flows into the common pipe 51 from the second inlet 55. At this time, the first check valve 53a is closed, and the second cleaning water W2 flows through the second flow path 56 of the common pipe 51 and is jetted upward from the nozzles 52 of the respective racks 50. In this way, the second cleaning water W2 is jetted from the rotary nozzle 40 and the nozzles 52.
[0175] The second cleaning water W2 jetted into the cleaning chamber 30 flows down while raising the temperature in the cleaning chamber 30, flows down into the first tank 10 through the filter member 38b of the partition member 38, and is stored as the first cleaning water W1.
[0176] When the water storage amount of the second cleaning water W2 in the second tank 20 decreases and the upper limit water level sensor 27a detects that it is not full, a signal is sent to the control unit 6. The control unit 6 opens the solenoid valve 28a of the water supply pipe 28 and supplies clean water to the second tank 20 until the upper limit water level sensor 27a detects full water. At this time, the control unit 6 continues heating by the second heating means 21 only when the lower limit water level sensor 27b does not detect that the water level of the second cleaning water W2 is lower than the lower limit water level.
[0177] When the control unit 6 detects that the second cleaning water W2 in the second tank 20 is full, it closes the solenoid valve 28a of the water supply pipe 28 and stops the water supply. When the second temperature sensor 22 detects that the second cleaning water W2 stored in the second tank 20 has reached a predetermined temperature, for example, 80 degrees C, the control unit 6 stops the second heating means 21. Then, the second cleaning water supply means 23 is driven to jet the second cleaning water W2 from the rotary nozzle 40 and the nozzles 52 of the rack 50 and store it in the first tank 10. This is repeated until the first tank 10 is filled to the full water level.
[0178] When the second cleaning water W2 fills the first tank 10, the upper limit water level sensor 17a detects the full water and sends a signal to the control unit 6. The control unit 6 stops the drive of the second cleaning water supply means 23.
[0179] At this time, since both the first check valve 53a and the second check valve 55a are closed, the second cleaning water W2 is stored in the common pipe 51.
[0180] The control unit 6 monitors the temperature of the stored cleaning water by the first temperature sensor 12 of the first tank 10, and when the temperature becomes lower than a predetermined temperature, the control unit 6 appropriately operates the first heating means 11 to control it to maintain the predetermined temperature. This continues until the first cleaning step S3 is started.
[0181] Then, when the control unit 6 detects that the temperature of the second cleaning water W2 stored up to the full water level in the second tank 20 has reached a predetermined temperature by the second temperature sensor 22, the control unit 6 stops the second heating means 21. Also, the control unit 6 monitors the temperature of the second cleaning water W2 stored by the second temperature sensor 22, and when the temperature becomes lower than a predetermined temperature, the control unit 6 appropriately operates the second heating means 21 to control it to maintain the predetermined temperature. This continues until the second cleaning step S4 is started.
[0182] In addition, a detergent supply means (not shown) is driven to put detergent into the first tank 10 so as to reach a predetermined concentration, and the first cleaning water W1 stored in the first tank 10 becomes the first cleaning water W1 containing detergent.
[0183] As shown in FIG. 20, the control unit 6 detects that the cleaning waters in the first tank 10 and the second tank 20 are both at a predetermined temperature and full, and notifies the operator by sounding a buzzer (not shown) provided in the operation unit 7 that the preparation for performing the cleaning steps S3 and S4 is completed, and the preparation step S1 ends.
[0184] (Loading Step) As shown in FIG. 6, after the preparation step S1, the door portion 4 is opened, the rack 50 in the cleaning chamber 30 is pulled out by hand, slid from the rack support portion 31 to the rack standby portion 5, and moved to the rack standby position. At this time, following the movement of the rack 50, the first connection pipe 62 and the second connection pipe 64 are deformed, and the connection portion 60 rotates with respect to the lower connection opening 35, so that it can move smoothly.
[0185] Then, the opening G1 of the bottle G is stored in the storage space 50a of the rack 50 in an inverted posture with the opening G1 facing downward. At this time, the opening G1 of the bottle G is stored so as to be inserted into the nozzle 52 of the rack 50, and the opening G1 of the bottle G is stored so as to be placed on the upper surface of the spacer 57.
[0186] After storing a plurality of bottles G in the rack 50, the rack 50 is held by hand and pushed, and carried from the rack standby position to a predetermined position of the rack support portion 31. At this time, following the movement of the rack 50, the first connection pipe 62 and the second connection pipe 64 are deformed, and the connection portion 60 rotates with respect to the lower connection opening 35, so that it can be carried in smoothly. When the rack 50 is carried into the predetermined position, the door portion 4 is closed, and the carry-in step S2 ends.
[0187] (First cleaning step) After the carry-in step S2, the cleaning operation start switch (not shown) of the operation unit 7 is operated to start the first cleaning step S3. The control unit 6 that has received a signal from the operation unit 7 detects that the door portion 4 is closed by the door sensor 4b, and starts driving the first cleaning water supply means 13. When the first cleaning water supply means 13 is driven, the first cleaning water flows through the first cleaning water flow system 71, and the first cleaning water W1 is sprayed from the rotary nozzle 40 and the nozzle 52 of the rack 50, and the bottle G is cleaned.
[0188] As shown in FIG. 21, the first washing water supply means 13 sucks the first washing water W1 from the first tank 10 and discharges it into the first washing pipe 14. The first washing water W1 discharged into the first washing pipe 14 branches from the first washing pipe 14 into the upper connection opening 32 and the lower connection opening 35, and flows into the respective first flow paths 33a, 36a.
[0189] The first washing water W1 that has flowed into the upper connection opening 32 flows into the first washing nozzle 41 of the rotary nozzle 40 through the first joint portion 42, and is sprayed downward from the spray port 41a for a predetermined time, for example, 75 seconds. The first washing water W1 that has come into contact with the bottle G washes away the dirt components adhering to the outer surface of the bottle G. Then, the first washing water W1 containing the dirt components flows down to the partition member 38 at the lower part of the washing chamber 30.
[0190] The first washing water W1 that has flowed into the lower connection opening 35 flows into the first connection pipe 62 through the first joint portion 61 of the connection portion 60, passes through the first check valve 53a, and flows into the common pipe 51 from the first inlet 53. At this time, the second check valve 55a is closed.
[0191] Then, the first washing water W1 that has flowed into the common pipe 51 flows through the first flow path 54 in the common pipe 51 and is sprayed upward from the spray ports 52a of the respective nozzles 52.
[0192] At this time, since the common pipe 51 is filled with the second washing water W2 stored in the preparation step S1, the second washing water W2 is pushed out by the first washing water W1 and is sprayed into the bottle G for a predetermined time before the first washing water W1.
[0193] As a result, before the first washing water W1 is ejected from each nozzle 52 after the first washing water supply means 13 is driven, the second washing water W2 can be ejected to wash the inside of the bottle G. In particular, since the second washing water W2 stored in the common pipe 51 in the preparation step S1 is at a higher temperature than the first washing water W1, for example, if the preparation step S1 and the first washing step S3 are carried out without leaving much time between them and the temperature drop is suppressed as much as possible until the first washing step S3 is started, the second washing water W2 at a higher temperature than the first washing water W1 can be ejected into the bottle G.
[0194] And, for example, when the dirt components inside the bottle G are oils and fats contained in sugars, seasonings, etc. contained in beverages, etc., by applying heat to the dirt components to increase their fluidity, they can then be washed with the first washing water W1. That is, the second washing water W2 can promote the removal of the dirt components with the first washing water W1.
[0195] As a result, the second washing water W2 at a higher temperature than the first washing water W1 can apply heat to the bottle G, which is the object to be washed, and the dirt components adhering to the bottle G in advance, and increase the fluidity of the dirt components. And it can promote the removal of the dirt components with the first washing water W1 and improve the washability of the bottle G.
[0196] Also, since the temperature of the bottle G itself can be increased by the second washing water W2 stored in the common pipe 51, it is possible to suppress the temperature drop when the first washing water W1 ejected after the second washing water W2 contacts the bottle G, suppress the drop of the first washing water W1 stored in the first tank 10 from a predetermined temperature, and reduce the energy for reheating the first washing water W1 to a predetermined temperature.
[0197] In addition to the first cleaning water W1 injected from the nozzle 52 of the rack 50 into the bottle G, the first cleaning water W1 is also injected from the first cleaning nozzle 41 of the rotary nozzle 40, and the outer surface of the bottle G is cleaned. At this time, the first cleaning water W1 injected from the first cleaning nozzle 41 cleans the outer surface of the bottle G and raises the temperature of the bottle G. Therefore, in addition to the dirt components adhering to the outer surface of the bottle G, heat from the first cleaning water W1 injected from the first cleaning nozzle 41 also acts on the dirt components adhering to the inner surface of the bottle G. And when the dirt components adhering to the bottle G are saccharides or oils and fats, the fluidity of the dirt components is increased, making it easier to wash them off.
[0198] Thereby, while injecting more cleaning water onto the bottle G, which is the object to be cleaned, to improve the cleaning power of the bottle G, the temperature of the bottle G can be raised, making it easier to remove the dirt adhering to the bottle G.
[0199] Also, since the second cleaning water W2 stored in the preparation step S1 fills the common pipe 51, in the first cleaning step S3, the amount of the first cleaning water W1 flowing in from the first inlet 53 can be reduced by the amount of the second cleaning water W2 stored in the common pipe 51, and the first cleaning step S3 can be started quickly.
[0200] And it is not necessary to set the driving time of the first cleaning water supply means 13 to the time including the time (time lag) until the cleaning water fills the common pipe 51 and is injected from the plurality of nozzles 52. The cleaning time of the bottle G, which is the object to be cleaned per time, can be made as short as possible, and the energy for injecting the cleaning waters W1 and W2 can be reduced.
[0201] Also, the cleaning waters W1 and W2 can be injected for a longer time from the start to the end of the first cleaning step S3 implemented for a predetermined time, and the cleanability of the bottle G cleaned in the first cleaning step S3 can be improved.
[0202] When the second cleaning water W2 stored in the common pipe 51 is replaced by the first cleaning water W1, the first cleaning water W1 is sprayed from each nozzle 52.
[0203] At this time, in the first flow path 54, the second cleaning water W2 and the first cleaning water W1 stored in the common pipe 51 in the preparation step S1 are such that the total amount of water sprayed from the second nozzle 52Y at the Y position is larger than the total amount of water sprayed from the first nozzle 52X at the X position. Details will be described later.
[0204] The second cleaning water W2 and the first cleaning water W1 sprayed inside the bottle G contact the inner surface of the bottle G or scatter inside the bottle G to wash away the dirt components. The cleaning water containing the dirt components flows down the inner surface of the bottle G or falls inside the bottle G and temporarily stays at the neck G4, and then flows out from the opening G1 through the notch 57a of the spacer 57 into the cleaning chamber 30. Then, the cleaning water containing the dirt components flows down to the partition member 38 at the lower part of the cleaning chamber 30.
[0205] In this way, the first cleaning water W1 is sprayed from the first cleaning nozzle 41 of the rotary nozzle 40, the second cleaning water W2 and the first cleaning water W1 are sprayed from the nozzle 52 of the rack 50 for a predetermined time, for example, 75 seconds, to clean the inner surface and the outer surface of the bottle G.
[0206] The cleaning water containing the dirt components flows down from the cleaning chamber 30 through the filter member 38b of the partition member 38 into the first tank 10, and is mixed with the first cleaning water W1 stored in the first tank 10 and stored. At this time, the dirt larger than the holes of the filter member 38b (such as leftover food) among the dirt mixed in the cleaning water containing the dirt components will be collected by the filter member 38b. Thereby, the decrease in the cleanliness of the first cleaning water W1 stored in the first tank 10 is suppressed, and the bottle G can be cleaned with cleaner cleaning water.
[0207] The first cleaning water W1 stored in the first tank 10 flows again through the first cleaning water flow system 71 by the first cleaning water supply means 13, is jetted from the rotary nozzle 40 and the nozzles 52 of the rack 50, and is used for cleaning the bottle G. Thus, the first cleaning water W1 is recycled.
[0208] After continuously driving for a predetermined time, the control unit 6 stops the first cleaning water supply means 13.
[0209] The inflow of the first cleaning water W1 from the first inlet 53 into the common pipe 51 stops, and the first check valve 53a closes. That is, both the first check valve 53a and the second check valve 55a are in a closed state, and the first cleaning water W1 is stored in the common pipe 51. Then, the control unit 6 maintains the state in which the cleaning water supply means 13 and 23 are stopped for a predetermined time, for example, 3 seconds, for draining the bottle G, and the first cleaning step S3 ends.
[0210] (Second cleaning step) After the first cleaning step S3, the control unit 6 drives the second cleaning water supply means 23 to start the second cleaning step S4.
[0211] As shown in FIG. 22, the second cleaning water supply means 23 sucks the second cleaning water W2 from the second tank 20 and discharges it to the second cleaning pipe 24. The second cleaning water W2 discharged to the second cleaning pipe 24 branches from the second cleaning pipe 24 to the upper connection opening 32 and the lower connection opening 35, and flows into the respective second flow paths 34a and 37a.
[0212] The second cleaning water W2 that has flowed into the upper connection opening 32 flows into the second cleaning nozzle 43 of the rotary nozzle 40 through the second joint portion 44 and is jetted downward from the jet port 43a for a predetermined time, for example, 12 seconds. The second cleaning water W2 that has contacted the bottle G washes away the first cleaning water W1 adhering to the outer surface of the bottle G and the dirt components that could not be washed away in the first cleaning step S3. Then, the second cleaning water W2 containing the dirt components that could not be washed away in the first cleaning water W1 and the first cleaning step S3 flows down to the partition member 38 at the lower part of the cleaning chamber 30.
[0213] The second cleaning water W2 that has flowed into the lower connection opening 35 flows into the second connection pipe 64 through the second joint portion 63 of the connection portion 60, passes through the second check valve 55a, and flows into the common pipe 51 from the second inlet 55. At this time, the first check valve 53a is closed.
[0214] Then, the second cleaning water W2 that has flowed into the common pipe 51 flows through the second flow path 56 in the common pipe 51 and is jetted upward from the jet ports 52a of the respective nozzles 52.
[0215] At this time, since the common pipe 51 is filled with the first cleaning water W1 stored in the first cleaning step S3, it is pushed out by the second cleaning water W2, and the first cleaning water W1 is jetted into the bottle G for a predetermined time before the second cleaning water W2.
[0216] As a result, in the second cleaning step S4, while reducing the amount of the second cleaning water W2 flowing in from the second inlet 55 by the amount of the first cleaning water W1 stored in the common pipe 51 in the first cleaning step S3, the second cleaning step S4 can be started quickly.
[0217] Then, it is not necessary to set the driving time of the second cleaning water supply means 23 to a time including the time (time lag) until the cleaning water fills the common pipe 51 and is sprayed from the plurality of nozzles 52. The cleaning time of the bottle G, which is the object to be cleaned each time, can be made as short as possible, and the energy for spraying the cleaning waters W1 and W2 can be reduced.
[0218] Also, the cleaning waters W1 and W2 can be sprayed for a longer time from the start to the end of the second cleaning step S4 that is carried out for a predetermined time, and the cleanability of the bottle G cleaned in the second cleaning step S4 can be improved.
[0219] In addition to the second cleaning water W2 sprayed from the nozzles 52 of the rack 50 into the bottle G, the second cleaning water W2 is also sprayed from the second cleaning nozzles 43 of the rotary nozzle 40, and the outer surface of the bottle G is cleaned. At this time, the second cleaning water W2 sprayed from the second cleaning nozzles 43 cleans the outer surface of the bottle G and also raises the temperature of the bottle G. For this reason, in addition to the dirt components adhering to the outer surface of the bottle G that could not be completely removed in the first cleaning step S3, the heat of the second cleaning water W2 sprayed from the second cleaning nozzles 43 also acts on the dirt components adhering to the inner surface of the bottle G. And when the dirt components adhering to the bottle G are saccharides or oils and fats, the fluidity of the dirt components is increased, making them easier to wash off.
[0220] Thereby, while spraying more cleaning water on the bottle G, which is the object to be cleaned, to improve the cleaning power of the bottle G, the temperature of the bottle G can be raised, making it easier to remove the dirt adhering to the bottle G.
[0221] Then, when the first cleaning water W1 stored in the common pipe 51 is replaced by the second cleaning water W2, the second cleaning water W2 is sprayed from each nozzle 52.
[0222] At this time, in the second flow path 56, unlike the first flow path 54, the total amount of the first cleaning water W1 and the second cleaning water W2 stored in the common pipe 51 in the first cleaning step S3 is less than the total amount of water jetted from the second nozzle 52Y at the Y position than the total amount of water jetted from the first nozzle 52X at the X position. Details will be described later.
[0223] The first cleaning water W1 and the second cleaning water W2 stored in the common pipe 51 and jetted inside the bottle G contact the inner surface of the bottle G or scatter inside the bottle G, and wash away the dirt components that could not be completely removed in the first cleaning step S3 and adhered to the inner surface of the bottle G. The cleaning water containing the dirt components that could not be completely removed in the first cleaning step S3 flows down the inner surface of the bottle G or falls inside the bottle G, temporarily stays at the neck portion G4, and then flows out from the bottle G to the cleaning chamber 30 through the notch portion 57a of the spacer 57 from the opening G1. Then, the cleaning water containing the dirt components that could not be completely removed in the first cleaning step S3 flows down to the partition member 38 at the lower part of the cleaning chamber 30.
[0224] At this time, after the first cleaning water W1 stored in the common pipe 51 is replaced by the second cleaning water W2, the second cleaning water W2 jetted from each nozzle 52 washes away the first cleaning water W1 adhered to the inner surface of the bottle G and the dirt components that could not be completely removed in the first cleaning step S3.
[0225] In this way, the second cleaning water W2 is jetted from the second cleaning nozzle 43 of the rotary nozzle 40, and the first cleaning water W1 and the second cleaning water W2 are jetted from the nozzle 52 of the rack 50 for a predetermined time, for example, 12 seconds, to clean the inner surface and the outer surface of the bottle G.
[0226] The washing water containing the dirt components that could not be completely removed in the first washing step S3 flows down from the washing chamber 30 through the filter member 38b of the partition member 38 into the first tank 10, mixes with the first washing water W1 stored in the first tank 10, and is stored as the first washing water W1. At this time, among the dirt mixed in the washing water, dirt (such as leftover food) larger than the holes of the filter member 38b will be collected by the filter member 38b. Thereby, the decrease in the cleanliness of the first washing water W1 stored in the first tank 10 is suppressed, and the bottle G can be washed with cleaner washing water.
[0227] Also, the amount of washing water in the first tank 10 increases by the amount of the second washing water W2 sprayed from the second washing nozzle 43 of the rotary nozzle 40 and the nozzle 52 of the rack 50 in the washing chamber 30. The increased washing water overflows from the upper end of the overflow and drain plug 16 and is drained through the drain pipe 15a to the drainage ditch on the facility side from the washing device 1.
[0228] Thereby, the dirt components that have passed through the filter member 38b floating near the water surface of the first tank 10 are drained together with the washing water, so that the decrease in the cleanliness of the first washing water W1 stored in the first tank 10 can be suppressed.
[0229] Also, when the second washing water W2 is clean water, since the second washing water W2 has a higher cleanliness (cleaner) compared to the first washing water W1, the cleanliness of the first washing water W1 can be increased by mixing it with the first washing water W1.
[0230] In this case, when the second washing water W2, which is clean water, mixes with the first washing water W1, the detergent concentration of the first washing water W1 will decrease. However, a detergent concentration sensor (not shown) detects the concentration decrease and sends a signal to the control unit 6. The control unit 6 controls the driving of a detergent supply means (not shown) to input detergent into the first tank 10 so as to reach a predetermined concentration. Thereby, the detergent concentration of the first washing water W1 can be maintained.
[0231] After driving the second cleaning water supply means 23 continuously for a predetermined time, the control unit 6 stops it.
[0232] The inflow of the cleaning water into the common pipe 51 from the second inlet 55 stops, and the second check valve 55a closes. That is, both the first check valve 53a and the second check valve 55a are in a closed state, and the second cleaning water W2 is stored in the common pipe 51. Then, after a predetermined time, for example, 3 seconds, has elapsed for draining the bottle G, the control unit 6 notifies the operator by sounding a buzzer that the second cleaning step S4 has ended, and the second cleaning step S4 ends.
[0233] (Carrying-out step) After the second cleaning step S4 ends, the rack 50 is carried out from the cleaning chamber 30.
[0234] As shown in FIGS. 4 and 6, the door portion 4 is opened, the rack 50 storing the bottle G is pulled out by hand, and carried out from the rack support portion 31 to a predetermined position of the rack standby portion 5. At this time, following the movement of the rack 50, the first connection pipe 62 and the second connection pipe 64 are deformed, and the connection portion 60 rotates, so that it can be carried out smoothly. Then, the washed bottle G is taken out from the rack 50, and one-time cleaning ends.
[0235] (Regarding the cleaning cycle) After performing from the preparation step S1 and finishing the first carrying-out step S5, when continuously cleaning the bottle G, a cleaning cycle can be performed by repeating from the second preparation step S1 to the carrying-out step S5.
[0236] To perform the cleaning cycle, the second cleaning water W2 in the second tank 20 whose water level has dropped by performing the second cleaning step S4 is stored again up to full water and heated to a predetermined temperature, and the second preparation step S1 is performed.
[0237] The second preparation step S1 is different from the first preparation step S1 described above in that it is carried out from the state where the first cleaning water W1 has already been stored in the first tank 10 until it is full. That is, in the second preparation step S1, in order to store the cleaning water in the first tank 10, the second cleaning water supply means 23 does not spray the second cleaning water W2 from the rotary nozzle 40 and the nozzle 52 of the rack 50, but stores the second cleaning water W2, which is fresh water, in the second tank 20 until it is full, and heats and maintains the temperature of the second cleaning water W2 until it reaches a predetermined temperature.
[0238] Specifically, during the implementation of the second cleaning step S4, the upper limit water level sensor 27a of the second tank 20 detects that the second cleaning water W2 is not full and sends a signal to the control unit 6. The control unit 6 sends a signal to the solenoid valve 28a of the water supply pipe 28 to open it and starts storing fresh water until it is full. When the upper limit water level sensor 27a detects that it is full, it sends a signal to the control unit 6 to close the solenoid valve 28a. Then, the control unit 6 operates the second heating means 21 to heat the second cleaning water W2 and maintain it at a predetermined temperature.
[0239] When the second cleaning step S4 ends, since the first cleaning water W1 has been stored in the first tank 10 until it is full, the control unit 6 detects that the upper limit water level sensor 17a of the first tank 10 is full and operates the first heating means 11 to heat the first cleaning water W1 to a predetermined temperature and maintain it at the predetermined temperature.
[0240] Then, the control unit 6 prepares for the next first cleaning step S3 with the state that both the first cleaning water W1 stored in the first tank 10 and the second cleaning water W2 stored in the second tank 20 are stored until they are full at a predetermined temperature.
[0241] After the unloading step S5, the operator takes out the washed bottle G from the rack 50, then stores the bottle G before washing, which is to be washed next, in the rack 50, and performs the second loading step S2 of carrying the rack 50 storing the bottle G into the washing chamber 30. After that, the second first washing step S3 is started, and the second washing step S4 and the unloading step S5 are performed in sequence.
[0242] When repeating the washing cycle, when the first second washing step S4 ends, the second washing water W2 is stored in the common pipe 51. Therefore, in the next second first washing step S3, before the first washing water W1 is sprayed, the second washing water W2 stored in the common pipe 51 can be sprayed toward the inside of the bottle G.
[0243] Thereby, the second washing water W2 having a temperature higher than that of the first washing water W1 can heat the bottle G, which is the object to be washed, and the dirt components attached to the bottle G in advance, and increase the fluidity of the dirt components. Then, the removal of the dirt components by the first washing water W1 can be promoted, and the cleanability of the bottle G can be improved.
[0244] In addition, since the cleanability of the bottle G by the first washing water W1 is improved, the time for performing the first washing step S3 can be shortened, the length of the washing time per time can be shortened as much as possible, and the energy for spraying the first washing water W1 can be reduced.
[0245] (Regarding the change in the length of the time for performing the washing step) In the cleaning device 1 of the first embodiment, by operating the operation unit 7, the control of each member by the control unit 6 is changed, and the length of time for performing the first cleaning step S3 and the length of time for performing the second cleaning step S4 can be changed. Then, by changing the length of time for performing the first cleaning step S3 and the length of time for performing the second cleaning step S4, the cleaning of the bottle G can be made more reliable without significantly increasing the energy consumption used for cleaning. Hereinafter, the cleaning method of the cleaning device 1 having such a configuration will be described.
[0246] Before explaining the method here, hypothetically, different from the first embodiment, a case will be described where in the first cleaning step S3, the first cleaning water W1 flows from the first inlet 53 into the common pipe 51, and in the second cleaning step S4, the second cleaning water W2 also flows from the first inlet 53 into the common pipe 51.
[0247] Generally, in a batch-type cleaning device for an object to be cleaned such as the cleaning device 1 of the first embodiment, in the cleaning of the object to be cleaned per time, the total amount of cleaning water sprayed from the nozzle closest to the inlet is less than the total amount of cleaning water sprayed from other nozzles.
[0248] Therefore, in the common pipe 51 shown in FIG. 9, even when the first cleaning water W1 flows from the first inlet 53 into the common pipe 51 in the first cleaning step S3 and the second cleaning water W2 flows from the first inlet 53 into the common pipe 51 in the second cleaning step S4, in the cleaning of the bottle G per time, the total amount of the first cleaning water W1 sprayed from the first nozzle 52X at the X position in the first cleaning step S3 is less than the total amount of the first cleaning water W1 sprayed from other nozzles 52. On the other hand, the total amount of the first cleaning water W1 sprayed from the second nozzle 52Y at the Y position is more than the total amount of the first cleaning water W1 sprayed from the first nozzle 52X at the X position.
[0249] Also, the total amount of the second cleaning water W2 jetted from the first nozzle 52X at the X position in the second cleaning step S4 is less than the total amount of the second cleaning water W2 jetted from the other nozzles 52, and the total amount of the second cleaning water W2 jetted from the second nozzle 52Y at the Y position is more than the total amount of the first cleaning water W1 jetted from the first nozzle 52X at the X position.
[0250] As a result, in the cleaning of the bottle G per time, the total amount of the cleaning waters W1 and W2 jetted from the first nozzle 52X at the X position is less than the total amount of the cleaning waters W1 and W2 jetted from the other nozzles 52, and the total amount of the cleaning waters W1 and W2 jetted from the second nozzle 52Y at the Y position is extremely more than the total amount of the cleaning waters W1 and W2 jetted from the first nozzle 52X at the X position.
[0251] And although there are differences depending on the length of time for performing the cleaning steps S3 and S4, the bottle G cleaned by the nozzle 52 with an extremely small total amount of the cleaning waters W1 and W2 to be jetted, particularly the first nozzle 52X, may not be cleaned to a desired level. Also, from the nozzle 52 with an extremely large total amount of the cleaning waters W1 and W2 to be jetted, particularly the second nozzle 52Y, there is a possibility that the cleaning water is jetted more than necessary.
[0252] Also, even if the cleaning waters W1 and W2 are made to flow into the common pipe 51 from the second inlet 55 which is the same inlet in any of the cleaning steps S3 and S4 and made to flow through the second flow path 56 which becomes the same flow path, the total amount of the cleaning waters W1 and W2 jetted by the nozzle 52 may be extremely small or extremely large.
[0253] And in these cases, when trying to clean the bottle G washed with the washing water W1 and W2 jetted from the first nozzles 52X at the X position and the bottle G washed with the washing water W1 and W2 jetted from the second nozzles 52Y at the Y position to a desired level, based on the nozzles 52 where the total amount of the washing water W1 and W2 jetted in each washing of the bottle G is extremely small, the length of the time for performing the first washing step S3 and the length of the time for performing the second washing step S4 will be adjusted. By adjusting the length of the time for performing the washing steps S3 and S4, the total amount of the washing water W1 and W2 jetted in each washing of the bottle G will be adjusted.
[0254] For example, when the washing water W1 and W2 are made to flow from the first inlet 53, which is the same inlet for both washing steps S3 and S4, into the common pipe 51 and flow through the first flow path 54, which is the same flow path, the length of the time for performing the washing steps S3 and S4 will be changed to extend the time so as to increase the total amount of the washing water W1 and W2 from the first nozzles 52X at the X position where the total amount of the washing water W1 and W2 jetted in each washing of the bottle G is extremely small.
[0255] As a result, both the bottle G washed with the washing water W1 and W2 jetted from the first nozzles 52X at the X position and the bottle G washed with the washing water W1 and W2 jetted from the second nozzles 52Y at the Y position can be washed to the desired level. However, from the second nozzles 52Y at the Y position where the total amount of the washing water W1 and W2 jetted in each washing of the bottle G is extremely large, more washing water W1 and W2 will be jetted more than necessary, and the energy consumed by the washing water supply means 13 and 23 for discharging the washing water W1 and W2 will increase wastefully.
[0256] On the other hand, in the washing method using the washing apparatus 1 of the first embodiment, as shown in FIG. 21, in the first washing step S3, the first washing water W1 is made to flow from the first inlet 53 into the common pipe 51 and flow through the first flow path 54.
[0257] As a result, in the first cleaning step S3 per cycle, the total amount of the first cleaning water W1 ejected from the first nozzle 52X at the X position shown in FIG. 11 is less than the total amount of the first cleaning water W1 ejected from the second nozzle 52Y at the Y position, and the total amount of the first cleaning water W1 ejected from the second nozzle 52Y at the Y position is more than the total amount of the first cleaning water W1 ejected from the first nozzle 52X at the X position.
[0258] Also, as shown in FIG. 22, in the second cleaning step S4, the second cleaning water W2 is made to flow from the second inlet 55 to the common pipe 51 and flow through the second flow path 56.
[0259] As a result, in the second cleaning step S4 per cycle, the total amount of the second cleaning water W2 ejected from the second nozzle 52Y at the Y position shown in FIG. 12 is less than the total amount of the second cleaning water W2 ejected from the first nozzle 52X at the X position, and the total amount of the second cleaning water W2 ejected from the first nozzle 52X at the X position is more than the total amount of the second cleaning water W2 ejected from the second nozzle 52Y at the Y position.
[0260] In this way, in the first cleaning step S3 and the second cleaning step S4, by making the positions of the inlets 53 and 55 through which the cleaning waters W1 and W2 flow into the common pipe 51 different and making them flow through different flow paths 54 and 56 in the common pipe 51, the nozzle 52 with a small total amount of water in the first cleaning step S3 can have a large total amount of water in the second cleaning step S4, and the nozzle 52 with a large total amount of water in the first cleaning step S3 can have a small total amount of water in the second cleaning step S4.
[0261] As a result, in the cleaning of the bottle G per cycle, it is possible to equalize the total amounts of the cleaning waters W1 and W2 ejected from the first nozzle 52X at the X position, which is closest to the first inlet 53, to the bottle G and the total amounts of the cleaning waters W1 and W2 ejected from the second nozzle 52Y at the Y position, which is closest to the second inlet 55, to the bottle G.
[0262] By equalizing the total amount of the washing waters W1 and W2 in this way, for example, when changing the length of the time for performing the first washing step S3 and the length of the time for performing the second washing step S4 to such an extent that a bottle G that could not be washed to a desired level can be washed to the desired level, the change amount of the length of the time for performing the first washing step S3 and / or the length of the time for performing the second washing step S4 can be made as short as possible. That is, the length of the time for performing the first washing step S3 and / or the length of the time for performing the second washing step S4 can be shortened as compared with the case where equalization is not performed.
[0263] As a result, the driving time of the washing water supply means 13 and 23 for injecting the washing waters W1 and W2 in the washing steps S3 and S4 can be shortened, the total amount of the washing water injected from the entire plurality of nozzles 52 can be reduced, and the energy for injecting the washing water can be reduced.
[0264] And, as compared with the case where equalization is not performed, the washing of the bottle G as an object to be washed can be made more reliable without significantly increasing the consumption amount of the energy used for washing.
[0265] Also, as shown in FIG. 23, as compared with the case where equalization of the total amounts of the washing waters W1 and W2 is not attempted, the total amount of the second washing water W2 injected in the second washing step S4 can be made larger at the first nozzle 52X at the X position and smaller at the second nozzle 52Y at the Y position. That is, a part of the second washing water W2 injected more than necessary from the second nozzle 52Y at the Y position can compensate for the shortage of the total amount of the second washing water W2 injected from the first nozzle 52X at the X position.
[0266] Note that the length of the time for performing the first washing step S3 and the length of the time for performing the second washing step S4 may be extended or shortened for both times, or only the length of one of the times may be extended or shortened. Or, one of them may be extended and the other may be shortened.
[0267] (Regarding the first washing water stored in the common pipe) Also, in the washing of the bottle G per cycle, in the second washing step S4, before the second washing water W2 flowing from the second inlet 55 into the common pipe 51 is ejected from the plurality of nozzles 52, the first washing water W1 stored in the common pipe 51 in the first washing step S3 is ejected for a predetermined time.
[0268] At this time, the first washing water W1 stored in the common pipe 51 is ejected so as to be pushed out from the plurality of nozzles 52 by the second washing water W2 flowing from the second inlet 55 into the common pipe 51 and flowing through the second flow path 56.
[0269] As a result, the total amount of the first washing water W1 stored in the common pipe 51 and ejected from the first nozzle 52X at the X position is larger than the total amount of the first washing water W1 ejected from the second nozzle 52Y at the Y position, and the total amount of the first washing water W1 stored in the common pipe 51 and ejected from the second nozzle 52Y at the Y position is smaller than the total amount of the first washing water W1 ejected from the first nozzle 52X at the X position.
[0270] That is, the first washing water W1 stored in the common pipe 51 is ejected in a larger amount of the first washing water W1 stored from the first nozzle 52X at the X position where the total amount of the first washing water W1 ejected in the first washing step S3 was small, and the first washing water W1 stored in the common pipe 51 is ejected in a smaller amount from the second nozzle 52Y at the Y position where the total amount of the first washing water W1 ejected in the first washing step S3 was large.
[0271] As a result, in the washing of the bottle G per cycle, the total amount of the first washing water W1 ejected from the first nozzle 52X at the X position and the second nozzle 52Y at the Y position can be equalized.
[0272] And when the first washing water W1 is washing water containing a detergent, the cleaning effect (cleaning degree) of the first washing water W1 with the detergent can be equalized among the plurality of bottles G.
[0273] In addition, the length of time for allowing the first washing water W1 to flow into the common pipe 51 from the first inlet 53 can be shortened by the amount of the first washing water W1 stored in the common pipe 51 in the first washing step S3.
[0274] As a result, the driving time of the first washing water supply means 13 for jetting the first washing water W1 in the first washing step S3 can be shortened, the total amount of the washing water jetted from the entire plurality of nozzles 52 can be reduced, and the energy for jetting the washing waters W1 and W2 can be reduced.
[0275] And, compared with the case where equalization is not performed, the washing of the bottle G, which is the object to be washed, can be made more reliable without significantly increasing the energy consumption for performing the washing.
[0276] In the first embodiment, the common pipe 51 has been described by way of example as a single continuous pipe forming the first flow path 54 and the second flow path 56. However, instead of the common pipe 51, a pipe forming the first flow path 54 and a pipe forming the second flow path 56 may be provided adjacent to each other, and a plurality of nozzles 52 communicating with the respective pipes may be provided.
[0277] Specifically, one flow path is formed by a single pipe having one end and the other end and being closed at both ends, with an inlet on one end side of the pipe and the other end side being closed. Two pipes configured in this way are prepared, and one pipe is used as a first pipe 81 forming the first flow path 54, and the other pipe is used as a second pipe 82 forming the second flow path 56, and they are arranged adjacent to each other.
[0278] A plurality of nozzles 52 are attached to the first pipe 81 and the second pipe 82 at predetermined positions respectively. When the first pipe 81 and the second pipe 82 are arranged adjacent to each other, the plurality of nozzles 52 of the first pipe 81 and the plurality of nozzles 52 of the second pipe 82 are configured to be adjacent to each other. In this case, it is preferable to configure such that the adjacent nozzles 52 can be inserted together from the opening G1 of the bottle G, which is the object to be cleaned, into the bottle G.
[0279] Then, a first inlet 53 is provided on one end side of the first pipe 81, and a second inlet 55 is provided on one end side of the second pipe 82. When the first pipe 81 and the second pipe 82 are arranged adjacent to each other, the first inlet 53 and the second inlet 55 are configured to be at different positions. For example, when the first pipe 81 and the second pipe 82 are formed of pipes having substantially the same shape, the end of the first pipe 81 on the side where the first inlet 53 is provided and the end of the second pipe 82 on the terminal side are arranged to be adjacent to each other. Further, the end of the second pipe 82 on the side where the second inlet 55 is provided and the end of the first pipe 81 on the terminal side are arranged to be adjacent to each other. By arranging in this way, the positions of the first inlet 53 and the second inlet 55 are at different positions.
[0280] Among the plurality of nozzles 52 of the first pipe 81, the nozzle having the shortest flow path length from the first inlet 53 is defined as the first nozzle 52X at the X position, and among the plurality of nozzles 52 of the second pipe 82, the nozzle having the shortest flow path length from the second inlet 55 is defined as the second nozzle 52Y at the Y position.
[0281] By configuring in this way, the flow path length from the first inlet 53 of the first pipe 81 to the first nozzle 52X at the X position is shorter than the flow path length from the first inlet 53 to the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position of the second pipe 82. That is, the first nozzle 52X at the X position is at a position where the distance from the first inlet 53 of the first pipe 81 is closer than the distance from the first inlet 53 to the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position of the second pipe 82.
[0282] Conversely, the flow path length from the first inlet 53 of the first pipe 81 to the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position of the second pipe 82 is longer than the flow path length from the first inlet 53 to the first nozzle 52X at the X position. That is, the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position of the second pipe 82 is at a position farther from the first inlet 53 of the first pipe 81 than the distance from the first inlet 53 to the first nozzle 52X at the X position.
[0283] Also, the flow path length from the second inlet 55 of the second pipe 82 to the second nozzle 52Y at the Y position is shorter than the flow path length from the second inlet 55 to the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position of the first pipe 81. That is, the second nozzle 52Y at the Y position is at a position closer to the second inlet 55 of the second pipe 82 than the distance from the second inlet 55 to the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position of the first pipe 81.
[0284] Conversely, the flow path length from the second inlet 55 of the second pipe 82 to the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position of the first pipe 81 is longer than the flow path length from the second inlet 55 to the second nozzle 52Y at the Y position. That is, the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position of the first pipe 81 is at a position farther from the second inlet 55 of the second pipe 82 than the distance from the second inlet 55 to the second nozzle 52Y at the Y position.
[0285] Even when configured in this way, in the first cleaning step S3, the total amount of the first cleaning water W1 jetted from the first nozzle 52X at the X position, which is the position closest to the first inlet 53 in the first pipe 81, and the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position, which is the position closest to the second inlet 55 in the second pipe 82, is such that the first nozzle 52X at the X position is less than the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position. Conversely, the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position is more than the first nozzle 52X at the X position.
[0286] Also, in the second cleaning step S4, the total amount of the second cleaning water W2 jetted from the second nozzle 52Y at the Y position, which is the position closest to the second inlet 55 in the second pipe 82, and the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position, which is the position closest to the first inlet 53 in the first pipe 81, is such that the second nozzle 52Y at the Y position is less than the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position. Conversely, the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position is more than the second nozzle 52Y at the Y position, and the same operation as that described in this embodiment can be exhibited.
[0287] Thereby, among the plurality of nozzles 52 communicating with the first pipe 81 and the second pipe 82 respectively, the total amount of the cleaning water jetted from the first nozzle 52X at the X position and the nozzle 52 in the second pipe 82 adjacent to the first nozzle 52X at the X position, and the second nozzle 52Y at the Y position and the nozzle 52 in the first pipe 81 adjacent to the second nozzle 52Y at the Y position, is made different between the first cleaning step S3 and the second cleaning step S4, so that the total amount of the cleaning water jetted onto the bottle G, which is the object to be cleaned, in each cleaning can be equalized.
[0288] Then, when changing the length of time for performing the first cleaning step S3 and / or the second cleaning step S4 so that cleaning water with a desired total amount is ejected from the nozzles 52 with a small total amount of the cleaning water ejected among the plurality of nozzles 52 in each cleaning, compared with the case where the total amount of the cleaning water ejected from the first nozzle 52X at the X position, the nozzles 52 provided in the second pipe 82 adjacent to the first nozzle 52X at the X position, the second nozzle 52Y at the Y position, and the nozzles 52 provided in the first pipe 81 adjacent to the second nozzle 52Y at the Y position is not equalized, even if the total amount of the cleaning water ejected from the nozzles is set to the desired total amount, the length of time for performing the first cleaning step S3 and / or the second cleaning step S4 can be shortened.
[0289] As a result, the total amount of the cleaning waters W1 and W2 ejected from the entire plurality of nozzles 52 can be reduced, and the energy for ejecting the cleaning waters W1 and W2 can be reduced.
[0290] And, compared with the case where equalization is not performed, the cleaning of the bottle G, which is the object to be cleaned, can be made more reliable without significantly increasing the energy consumption for performing the cleaning.
[0291] Further, by providing the first check valve 53a at the first inlet 53 so that the cleaning water in the first pipe 81 does not flow backward to the side of the first cleaning water supply means 13, the first cleaning water W1 can be stored in the first pipe 81 after the first cleaning step S3.
[0292] Thereby, in the second first cleaning step S3 in the cleaning cycle, while reducing the amount of the first cleaning water W1 flowing in from the first inlet 53 by the amount of the first cleaning water W1 stored in the first pipe 81 in the first first cleaning step S3, the first cleaning water W1 can be quickly ejected from the plurality of nozzles 52.
[0293] In addition, a second check valve 55a is provided at the second inlet 55 so that the cleaning water in the second pipe 82 does not flow back to the side of the second cleaning water supply means 23. Thus, after the second cleaning step S4, the second cleaning water W2 can be stored in the second pipe 82.
[0294] Accordingly, in the second cleaning step S4 of the second time during the execution of the cleaning cycle, while reducing the amount of the second cleaning water W2 flowing in from the second inlet 55 by the amount of the second cleaning water W2 stored in the second pipe 82 during the first second cleaning step S4, the second cleaning water W2 can be quickly jetted from the plurality of nozzles 52.
[0295] And, it is not necessary to set the driving time of the cleaning water supply means 13 and 23 to the time (time lag) until the cleaning water fills the first pipe 81 or the second pipe 82 and is jetted from the plurality of nozzles 52. Thus, the cleaning time of the bottle G, which is the object to be cleaned each time, can be made as short as possible, and the energy for jetting the cleaning water can be reduced.
[0296] Also, when the cleaning steps S3 and S4 are each carried out for a predetermined time, as compared with the case where the cleaning water is not stored in the first pipe 81 and the second pipe 82, the cleaning water W1 and W2 can be jetted from the plurality of nozzles 52 for a longer time from the start to the end of the cleaning steps S3 and S4, and the cleanability of the bottle G, which is the object to be cleaned, can be improved.
[0297] In addition, although the case where the first pipe 81 and the second pipe 82 are arranged adjacent to each other together with a plurality of nozzles 52 provided respectively has been described, for example, the pipe in the common pipe 51 may be partitioned into two regions along the pipe length direction, and one pipe may be the first pipe 81 forming the first flow path 54, and the other pipe may be the second pipe 82 forming the second flow path 56. That is, the pipes partitioned into two regions are also in an adjacent state to each other. In this case, a plurality of nozzles are provided with a plurality of nozzles communicating with the first pipe 81 and the second pipe 82. For example, as one nozzle having two injection ports, the inside of the nozzle may be partitioned into two regions along the pipe length direction, and one injection port may be communicated with the first pipe 81, and the other injection port may be communicated with the second pipe 82. Also in this case, the above-described effects can be similarly exhibited.
[0298] Also, regarding the predetermined temperature of the washing water, although the first washing water W1 has been described as 60 degrees C and the second washing water W2 has been described as 80 degrees C, it is not limited thereto. It can be appropriately changed according to the type of dirt component to be washed.
[0299] Further, the cleaning device 1 may be configured not to include either the first tank 10 and the first washing water supply means 13, or the second tank 20 and the second washing water supply means 23. Alternatively, it may be configured not to include both.
[0300] When the first tank 10 and the first washing water supply means 13 are not provided, for example, a water pipe for supplying the first washing water W1 is connected to the first washing pipe 14. And it is preferable to provide the first heating means 11 or the like for heating the first washing water W1 in-line in the first washing pipe 14.
[0301] When the second tank 20 and the second washing water supply means 23 are not provided, for example, a water pipe for supplying the second washing water W2 is connected to the second washing pipe 24. Also, it is preferable to provide the second heating means 21 or the like for heating the second washing water W2 in-line in the second washing pipe 24.
[0302] In addition, since the connection part 60 is detachably connected to the lower connection opening 35, a plurality of racks 50 corresponding to the shape and size of the bottle G can be prepared, and the rack 50 can be replaced according to the shape and size of the bottle G to be cleaned.
[0303] In addition, the object to be cleaned is not limited to the bottle G, and it may be tableware or the like. In that case, the storage space 50a of the rack 50 is not a lattice shape for storing the bottle G in an inverted posture, but may be, for example, a flat net shape in which tableware such as bowls and plates can be placed in a face-down posture (with the food serving surface facing downward) above the tip of the nozzle 52. Thereby, it is possible to perform cleaning that equalizes the degree of cleaning in one cleaning.
[0304] In addition, the nozzle connected to the upper connection opening 32 is not limited to the rotary nozzle 40, and may be a nozzle fixed in the cleaning chamber 30, for example, the common pipe 51.
[0305] In addition, when there is a lot of dirt attached to the bottle G, before performing the first cleaning step S3, a preliminary cleaning step using the second cleaning water flow system 72 may be performed as in the second cleaning step S4. Thereby, heat can be applied to the object to be cleaned and the dirt component with the high-temperature second cleaning water W2, and so-called preliminary cleaning can be performed to promote the removal of the dirt component with the first cleaning water W1 in the first cleaning step S3.
[0306] In addition, since the second cleaning water W2 having a temperature higher than that of the first cleaning water W1 can be stored in the common pipe 51 in advance immediately before the first cleaning step S3, during the carry-in step S2 in the cleaning cycle, the second cleaning water W2 having a higher temperature than the second cleaning water W2 stored in the common pipe 51 with a decreased temperature can be sprayed into the bottle G in the first cleaning step S3. Thereby, the cleanability with the first cleaning water W1 in the first cleaning step S3 can be improved.
[0307] Also, in the cleaning cycle, after performing the unloading step S5, before performing the next loading step S2, the door portion 4 may be closed once, and the first cleaning step S3 may be performed in advance to store the first cleaning water W1 in the common pipe 51. As a result, in the first cleaning step S3, since the common pipe 51 is filled with the first cleaning water W1, when the first cleaning water W1 starts to be sprayed from the plurality of nozzles 52, the cleaning water that first touches the object to be cleaned can be the first cleaning water W1. Particularly when the first cleaning water W1 contains a detergent, the detergent can touch the object to be cleaned from the beginning, and the cleaning effect of the detergent can be exerted for a longer time in the first cleaning step S3.
[0308] The cleaning device 1 can also be used as a bottle cleaning machine by attaching the rack 50 together with the connecting portion 60 to the lower connection opening 35 instead of the rotary nozzle 40 attached to the lower connection opening 35, from a normal batch-type tableware cleaning machine with the rotary nozzle 40 attached to the upper connection opening 32 and the lower connection opening 35.
