JP-A-10-180212 (paragraphs [0017]-[0022], FIG. 1, FIG. 2)

  When many container-like objects to be cleaned (eg, baby bottles) are to be washed at one time, there are the following disadvantages if they are simply placed in a simple basket-like general purpose rack. That is, even if the opening (for example, the opening of the bottle) of the object to be cleaned is directed downward, the object to be cleaned may fall down by the jet flow at the time of cleaning, and the inside can not be cleaned. In addition, even if the object to be cleaned does not fall, there is a possibility that the inside of all the objects to be cleaned can not be reliably cleaned due to the positional relationship with the jet port of the cleaning nozzle (nozzle arm). Specifically, since the jet nozzles are formed at regular intervals in the cleaning nozzle, if the opening of the object to be cleaned is not disposed at the position corresponding to the jet openings, the cleaning water is introduced into the object to be cleaned. Can not be washed without Therefore, conventionally, when cleaning a container-like to-be-cleaned object, a rack provided with a jet nozzle (jet pipe) is used like the jet rack described above.

  However, also in this case, there are the following disadvantages. That is, there is a limit to the number of injection nozzles (and hence the number of sets of objects to be cleaned) in the jet rack. In addition to the limited space for installing the water pipe to the injection nozzle, the water pressure of the injection water and hence the cleaning effect decrease if the number of installation of the injection nozzle is increased, so the number of injection nozzles can not be increased.

  Further, in addition to the cleaning nozzle (nozzle arm) for each rack, water is also injected from the injection nozzle in the jet rack, so the water pressure is dispersed that much and the cleaning performance is lowered.

  Furthermore, if the object to be cleaned is inverted only on the injection nozzle (injection pipe), the object to be cleaned may oscillate due to the jet flow at the time of cleaning, contact with the adjacent object to be cleaned, and contact noise or damage may occur. is there. In addition, when the bottom surface in the object to be cleaned is in contact with the upper surface of the spray nozzle (wash pipe), there is a possibility that the jet water does not hit well and can not be cleaned.

As a result, the cleaning nozzle 4 can be rotated in the horizontal direction by the jet flow from the injection port 12. The cleaning nozzle 4 provided at the upper end in the cleaning tank 3 jets the liquid only downward, and the other cleaning nozzles 4 are basically in the present embodiment (that is, the cleaning nozzle 4 is rotated). The liquid is injected only upward (except for the injection port 12 of

  The liquid reservoir 5 is connected to the lower portion of the cleaning tank 3. Specifically, the liquid storage portion 5 is formed on the bottom surface of the cleaning tank 3 so as to be recessed downward. Conversely, the liquid storage portion 5 is provided on the bottom surface of the cleaning tank 3 so as to open upward. In addition, it is preferable that the bottom surface of the cleaning tank 3 be formed to be inclined downward toward the opening edge of the liquid storage portion 5.

  The water supply means 6 supplies water to the liquid storage unit 5 via the water supply passage 13. A water supply valve 14 is provided in the water supply passage 13. By opening the water supply valve 14, water can be supplied to the liquid storage unit 5. In addition, the water supply means 6 may be comprised so that supply of the water selected from multiple types of water (for example, tap water, warm water, membrane filtration water etc.) is possible.

  The drainage means 7 drains water from the liquid storage unit 5 via the drainage path 15. A drainage valve 16 is provided in the drainage passage 15. By opening the drain valve 16, it is possible to drain water from the washing tank 3 and the liquid storage unit 5.

  The chemical solution supply unit 8 supplies the chemical solution from the chemical solution tank 17 to the liquid storage unit 5 through the liquid supply passage 18. A chemical solution pump 19 is provided in the liquid supply passage 18. By operating the drug solution pump 19, it is possible to supply a set amount of drug solution to the liquid storage unit 5. The chemical solution supply unit 8 may be configured to be able to supply a chemical solution selected from a plurality of types of chemical solutions (for example, alkaline detergents, enzyme-containing detergents, lubricating rust inhibitors, drying accelerators, etc.).

  The circulation means 9 circulates and supplies the liquid in the liquid reservoir 5 to the cleaning nozzle 4. Specifically, the circulation means 9 includes a circulation pipe 20 and a circulation pump 21. The circulation pipe 20 is a pipe from the liquid reservoir 5 to the support member 11 of each cleaning nozzle 4, and a circulation pump 21 is provided in the middle thereof. A check valve 22 is provided on the outlet side of the circulation pump 21 in the circulation pipe 20. When the circulation pump 21 is operated, the liquid in the liquid storage unit 5 can be supplied to the cleaning nozzle 4 via the circulation pipe 20 and the support member 11 and jetted, and can be returned to the liquid storage unit 5 in the lower part of the cleaning tank 3 .

  The heating means 10 is comprised from the heater 23 provided in the liquid storage part 5 in the present Example. The heater 23 is an electric heater in the illustrated example, but may be a steam heater as the case may be.

  The liquid reservoir 5 is provided with a liquid level detector 24. The liquid level detector 24 is not particularly limited in its configuration, and is constituted of, for example, a pressure sensor installed at the bottom of the liquid reservoir 5. In this case, depending on the liquid level in the liquid storage unit 5 or the cleaning tank 3, the liquid level is grasped using the change in water pressure.

  The liquid storage unit 5 is provided with a temperature sensor 25. By controlling the heater 23 based on the temperature detected by the temperature sensor 25, the temperature of the stored liquid in the liquid storage portion 5 can be adjusted.

  In addition, the ultrasonic transducer 26 is provided in the cleaning device 1 as desired. In the illustrated example, ultrasonic transducers 26 are provided on the left and right inclined surfaces in the lower portion of the cleaning tank 3 respectively. The ultrasonic transducer 26 is connected to an ultrasonic oscillator to control oscillation. By operating the ultrasonic transducer 26 in a state in which the object to be cleaned B is immersed, the object to be cleaned B can be ultrasonically cleaned.

  The control means is a controller (not shown) connected to the liquid level detector 24 and the temperature sensor 25 in addition to the respective means 6 to 10 described above. Specifically, the feed water valve 14, the drainage valve 16, the chemical solution pump 19, the circulation pump 21, the heater 23, the ultrasonic oscillator (26), the liquid level detector 24, the temperature sensor 25, etc. are connected to the controller . Then, the controller cleans the object B in the cleaning tank 3 in accordance with a predetermined procedure (program). At this time, at least a shower cleaning operation described below can be performed.

  In the shower cleaning operation, the liquid is stored in the liquid storage unit 5, and the liquid is circulated and supplied to the cleaning nozzle 4 by the circulating unit 9, and is jetted from the cleaning nozzle 4 to the object to be cleaned B. Specifically, water is supplied to the liquid reservoir 5 by the water supply means 6 until the liquid level detector 24 detects the set water level. Since the water level drops when the circulation pump 21 is operated later, the set water level at the time of initial water supply may be above the liquid reservoir 5.

  After water supply to the liquid storage unit 5, a desired chemical solution is introduced into the liquid storage unit 5 by the chemical solution supply unit 8 as necessary. The chemical solution supplied by the chemical solution supply means 8 is supplied to the water supply by the water supply means 6 by a set amount so as to have a set concentration. Furthermore, the storage water in the liquid storage unit 5 is heated to the set temperature by the heating unit 10 as needed. The introduction of the chemical solution and the heating of the stored water may be performed not only before the operation of the circulation unit 9 but also during the operation of the circulation unit 9.

  In any case, in a state where a desired amount of liquid is stored in the liquid storage unit 5, the circulation pump 21 is operated to supply the stored liquid to the cleaning nozzle 4 via the circulation pipe 20 and the support member 11 and inject it. The cleaning object B is cleaned while rotating the cleaning nozzle 4. Then, the liquid jetted from each cleaning nozzle 4 is returned to the liquid reservoir 5 in the lower part of the cleaning tank 3. When a predetermined termination condition (for example, an elapse of a set time) is satisfied, the circulation pump 21 is stopped, and the liquid in the liquid storage unit 5 is discharged by the drainage unit 7.

  Typically, such shower cleaning operation is repeated to wash and rinse the object to be cleaned B. For example, pre-washing with cold water without adding chemical solution, main washing with warm water optionally containing detergent (typically multiple times), rinsing with warm water optionally containing rinsing agent (typically multiple times) Etc. are made sequentially.

Below, the washing rack 2 of a present Example is demonstrated concretely.
2 and 3 are schematic views showing the usage state of the cleaning rack 2 of the present embodiment, FIG. 2 is a longitudinal sectional view of a front view, FIG. 3 is a longitudinal sectional view of a side view, and FIG. The part is cut and shown. Moreover, FIG. 4 is a schematic perspective view which shows the basket 27 and the partition material 28 etc. which are mounted on the washing rack 2 of a present Example.

  As described above, the object to be cleaned B is taken in and out of the cleaning tank 3 via the cleaning rack 2. At this time, the object to be cleaned B is put in the basket 27 and placed on the shelf 2 a of the cleaning rack 2, and the whole cleaning rack 2 is taken in and out of the cleaning tank 3.

  The cleaning rack 2 is provided with substantially rectangular frame bodies 29 on the left and right sides, and is provided with shelves 2 a in a plurality of upper and lower stages so as to bridge the frame bodies 29. Specifically, as shown in FIG. 3, the left and right frame bodies 29 are horizontally arranged in an upper piece 29a, and front and rear pieces 29b, 29b extending downward from the front and rear ends of the upper piece 29a. The lower piece 29c connecting the lower ends of the front and rear pieces 29b and 29b forms a substantially rectangular shape as a whole. Then, as shown in FIG. 2, in the left and right frame bodies 29, the upper pieces 29 a are appropriately connected by the upper member 30, and the lower pieces 29 c are also appropriately connected by the lower member 31. Thereby, the washing rack 2 is configured in a substantially rectangular parallelepiped shape as a whole. The lower pieces 29c of the left and right frames 29 are provided with a plurality of wheels (not shown) spaced apart in the longitudinal direction, and these wheels are attached to the bottom (or the rails provided thereto) in the washing tank 3. By running, the washing rack 2 can be easily taken in and out of the washing tank 3.

  The washing rack 2 is provided with shelves 2 a in a plurality of upper and lower stages (two upper and lower stages in the illustrated example). Specifically, each shelf 2 a is held horizontally so as to bridge the left and right frame bodies 29. Each shelf 2a is constructed by assembling bars in a grid, but in some cases, it may be configured by punching metal or the like.

  A cleaning nozzle 4 is rotatably provided below the respective shelves 2a. Specifically, as shown in FIG. 2, a water distribution member 32 is provided along the vertical direction on one side of the central portion in the front-rear direction of the cleaning rack 2, and the water distribution member 32 is supported by the support member 11. The cleaning nozzle 4 is provided via. In FIG. 2, the water distribution member 32 is fixed to the frame 29 on the right side along the vertical direction, and the support member 11 is fixed to a plurality of upper and lower locations of the water distribution member 32 (lower by a predetermined dimension than each shelf 2 a) It is done. One end of each support member 11 is fixed to the water distribution member 32, and the other end extends to the lateral center of the washing rack 2. And the longitudinal direction center part of the washing nozzle 4 is rotatably hold | maintained at the extended front-end | tip part.

  The cleaning rack 2 and the pump 21 are detachably connected so that the liquid from the circulation pump 21 can be supplied to the cleaning nozzle 4 of the cleaning rack 2 in a state in which the cleaning rack 2 is accommodated in the cleaning tank 3. Specifically, when the cleaning rack 2 is stored at a predetermined position in the cleaning tank 3, the circulation pipe 20 from the circulation pump 21 is connected to the water supply port formed in the water distribution member 32 of the cleaning rack 2. Therefore, when the circulation pump 21 is operated, the liquid from the liquid storage unit 5 is supplied from the circulation pipe 20 to the cleaning nozzle 4 through the water distribution member 32 and the support member 11.

  The object to be cleaned B is placed on the shelf 2 a of the cleaning rack 2 via the basket 27. In the present embodiment, as shown in FIG. 2, two baskets 27 are placed side by side on the upper and lower shelves 2 a respectively viewed from the front. Each basket 27 has the same configuration (the same shape and size). When the washing rack 2 and the basket 27 are viewed in a plan view, the size of each basket 27 substantially corresponds to the size obtained by dividing the shelf 2 a of the washing rack 2 into two equal halves. Therefore, two baskets 27 can be placed side by side on the shelf 2 a of the washing rack 2. At that time, by arranging the two baskets 27 adjacent to each other (arranging the side edges so as to be in contact), the baskets 27 are arranged in a substantially rectangular shape as a whole and at the shelf 2 a of the washing rack 2. Centrally located. That is, in a state where the cleaning rack 2 carrying the plurality of baskets 27 is accommodated in the cleaning tank 1 and viewed in a plan view, the plurality of baskets 27 arranged in the cleaning tank 1 on the rotation shaft of the cleaning nozzle 4 The central part of will be located.

  As shown in FIG. 4, the basket 27 is in the form of a substantially rectangular box that opens upward. The front and rear, right and left sides and the bottom of the basket 27 are formed of a mesh material or a perforated plate. In the illustrated example, the basket 27 is provided with a wire mesh in a frame made of a wire, but may be made of punching metal. Alternatively, the wires may be combined in a grid shape. In any case, it is preferable to provide the basket 27 with a handle 27a, for example, at the top of the front and rear sides.

  The inside of the basket 27 is partitioned in a lattice shape, and a plurality of storage portions for the object to be cleaned B are provided (symbols a to g in FIG. 5). In the illustrated example, by putting the partition member 28 in the basket 27, the inside of the basket 27 is partitioned in a grid shape. The partition member 28 is preferably composed of a plurality of horizontal plates 28a arranged with the plate surfaces facing back and forth, and a plurality of vertical plates 28b arranged with the plate surfaces facing left and right, which are preferably combined It is integrally formed of resin. The plurality of horizontal plates 28a are disposed in parallel at a constant interval, and the plurality of vertical plates 28b are disposed in parallel at a constant interval so as to be orthogonal to the horizontal plates 28a. In FIG. 4, the installation of the foremost and / or the last lateral plate 28 a may be omitted. Further, in the same figure, vertical plates 28b may be added along the left ends of the partition members 28 to connect the left ends of the horizontal plates 28a, or the right ends of the horizontal plates 28a may be connected. The vertical plate 28 b may be added along the right end portion of the partition member 28 as described above. In the partition member 28 (horizontal plate 28a, vertical plate 28b), an appropriate opening may be formed in the plate surface.

  By putting the partition member 28 in the basket 27, in the illustrated example, the basket 27 is partitioned into a total of 32 partitions, eight in front and back, and four in left and right. However, as will be described later, depending on the positional relationship between the jet nozzle 12 (12a to 12g) of the cleaning nozzle 4, only a part (specifically, 26) of them is the storage portion a to It functions as g.

  In a plan view of the washing rack 2 on which the basket 27 is placed, the basket 27 overlaps the rotation area of the washing nozzle 4 by a predetermined amount or more. Then, in the same plan view, among the sections partitioned by the partition member 28, a section overlapping the rotation area of the cleaning nozzle 4 by a predetermined amount or more (for example, 30% or more or 40% or more, preferably 50% or more) It is good to be taken as ~ g. The sections not used as the storage portions a to g may be configured to be unable to store the object to be cleaned B or to be marked unusable by appropriate means.

  The height of the partition member 28 corresponds to the height in the basket 27 in the illustrated example. That is, in the state in which the partition member 28 is put in the basket 27, the upper edge of the basket 27 and the upper edge of the partition member 28 are arranged at the corresponding height. However, in some cases, the upper edge of the partition member 28 may be disposed above the upper edge of the basket 27, or conversely, may be disposed below the upper edge of the basket 27.

  In each of the storage sections a to g, a hollow container (a baby bottle in the illustrated example) having an opening is stored as the cleaning object B. At this time, the container-like object to be cleaned B is stored in the storage portions a to g in the basket 27 with the mouth directed downward. The size of each of the storage portions a to g in the basket 27 is such that the to-be-cleaned object B does not fall down in accordance with the to-be-cleaned object B. It is sized so that it can be positioned in the placed state.

  FIG. 5 is a schematic plan view showing the rotation range of each injection port 12 (12a to 12g) of the cleaning nozzle 4 of the cleaning rack 2, in which the two baskets 27 are accommodated side by side on the shelf 2a of the cleaning rack 2. It is indicated by a two-dot chain line.

  As described above, the cleaning nozzle 4 is rotatable while injecting the liquid upward from the injection port 12, but the injection port 12 is formed at a position passing through each of the storage portions a to g. Conversely, among the compartments formed by partitioning the inside of the basket 27, the area to which the liquid jetted upward from the cleaning nozzle 4 hits is used as the storage parts a to g of the object to be cleaned B. In particular, in the case where the cleaning object B is a hollow container whose mouth is directed downward, the cleaning nozzle 4 of the cleaning rack 2 is a mouth of the cleaning object B held in each of the storage portions a to g. The injection port 12 is formed in the position which passes through.

  In FIG. 5, the cleaning nozzle 4 has at least one of the following requirements (a) to (g) as the injection port 12 in the process of rotating around the central portion in the longitudinal direction. In particular, it is preferable to provide a plurality of requirements (for example, (a) to (c) etc.), and it is preferable to have more requirements, and it is most preferable to have all the requirements. In the following, the two left and right baskets 27 of FIG. 5 are described without distinction (in other words, assuming that the two baskets 27 and 27 shown in FIG. 5 are one basket 27). As will be described later, how many baskets 27 achieve the state of FIG. 5 can be changed as appropriate.
