The tableware 2 rotates in the tableware basket 3. Although not shown, for example, the immersion water a in the immersion tank 21 is supplied by being pumped and supplied to the tableware rotation injection means 31 in the immersion tank 21, and the injection port portion of the tableware rotation injection means 31 is supplied. As the cleaning water (cleaning liquid) b sprayed from 34, the immersion water (immersion liquid) a in the immersion tank 21 is used.

  The cleaning chamber 22 includes a lower main cleaning chamber portion (first cleaning chamber portion) 41 and an upper main cleaning chamber portion (second cleaning chamber portion) positioned above the front side, which is one side of the lower main cleaning chamber portion 41. 42 and a finish cleaning chamber portion (third cleaning chamber portion) 43 positioned on the upper rear side, which is above the other side of the lower main cleaning chamber portion 41.

  Tableware in the tableware basket 3 being transported (moving) by the transport means 23 above the tableware basket moving region of the lower main cleaning chamber unit 41 (the region in which the tableware basket 3 moves in the lower main cleaning chamber unit 41). A plurality (for example, 12) of upper spraying means (upper cleaning nozzles) 46 for spraying curtain-like cleaning water b vertically downward with respect to 2 are disposed at intervals. Below the tableware basket movement area of the lower main washing chamber 41, the wash water b is obliquely above the tableware 2 in the tableware basket 3 being transferred (moved) by the transfer means 23 (moving direction of the tableware 2). A plurality of (for example, six) lower injection means (lower cleaning nozzles) 47 that inject toward the upper side of the horizontal direction are arranged at intervals.

  In the upper main cleaning chamber section 42, similarly to the lower main cleaning chamber section 41, a plurality (for example, six) of the upper injection means 46 and a plurality (for example, three) of the lower injection means 47 are provided in the tableware basket movement region. Are respectively disposed above and below. In the finishing cleaning chamber 43, as in the lower main cleaning chamber 41, a plurality (for example, seven) of the upper injection means 46 and a plurality (for example, four) of the lower injection means 47 are provided in the tableware basket movement region. Arranged above and below, respectively.

  The upper injection means 46 has a slit-like injection port portion 50 which is elongated in the left-right direction for injecting the curtain-like washing water b vertically downward to the tableware 2 in the tableware basket 3 on the horizontal lower surface. Yes.

  The lower injection means 47 includes a horizontal pipe portion 52 that is elongated in the left-right direction, and a plurality of nozzle portions 53 that are provided so as to protrude upward from the pipe portion 52 and are arranged in the left-right direction at intervals. doing. The nozzle portion 53 has a generally U shape when viewed from the front, and has an injection port portion 54 for injecting the washing water b obliquely upward toward the tableware 2 in the tableware basket 3 on the inclined upper end surface. ing. The longitudinal dimension of the pipe portion 52 is substantially the same as the longitudinal dimension of the slit-like ejection port portion 50 of the upper ejection means 46 (width dimension which is the lateral dimension of the conveying means 23) (see FIG. 2). .

  Further, the injection port portion 54 of each nozzle portion 53 provided in the pipe portion 52 of the lower injection means 47 disposed in each of the lower main cleaning chamber portion 41, the upper main cleaning chamber portion 42, and the finishing cleaning chamber portion 43. Are all directed in the same direction and are in the same direction as the injection port portion 34 of each nozzle portion 33 provided in the pipe portion 32 of the table rotating injection means 31 disposed in the immersion tank 21. .

  Note that the slit-shaped injection port portion 50 of the upper injection means 46 and the plurality of injection port portions 54 arranged at intervals in the longitudinal direction of the pipe portion 52 of the lower injection means 47 are located on the same vertical plane. The rotation of the tableware 2 due to the washing water from the injection port portion 54 of the lower injection means 47 is prevented from being weakened by the washing water from the injection port portion 50 of the upper injection means 46. ing. That is, the injection port portion 54 of the lower injection means 47 is arranged at a position slightly shifted from the position directly below the slit-shaped injection port portion 50 of the upper injection means 46 in the direction along the tableware movement direction.

  Further, as shown in FIG. 1, the cleaning water b in the main cleaning tank 56 is used for the main cleaning in the upper injection means 46 of the lower main cleaning chamber section 41 and the upper injection means 46 of the upper main cleaning chamber section 42. It is supplied from the main cleaning pipe 58 by the operation of the pump 57. Further, the cleaning water b in the finishing cleaning tank 61 is supplied from the finishing cleaning pipe 63 to the upper spraying means 46 of the finishing cleaning chamber 43 by the operation of the finishing cleaning pump 62.

  Although not shown, the cleaning water b in the main cleaning tank 56 is pumped and supplied to the lower jetting means 47 of the lower main cleaning chamber section 41 and the lower jetting means 47 of the upper main cleaning chamber section 42 to finish the cleaning chamber. The washing water b in the finishing washing tank 61 is pumped and supplied to the lower injection means 47 of the section 43.

  Further, a main cleaning water receptacle 59 is disposed below each of the lower injection means 47 of the lower main cleaning chamber section 41 and the lower injection means 47 of the upper main cleaning chamber section 42. Then, cleaning water (main cleaning water which is dirty waste water after cleaning) b that has entered the main cleaning water receiver 59 flows from the main cleaning water receiver 59 to the main cleaning tank 56. Further, a finishing cleaning water receiver 64 is disposed below the lower spraying means 47 of the finishing cleaning chamber 43. Then, the cleaning water (finish cleaning water which is dirty waste water after cleaning) b flowing in the finishing cleaning water receiver 64 flows from the finishing cleaning water receiver 64 to the finishing cleaning tank 61.

  Further, the conveying means 23 has a pair of left and right endless chains 71 that are opposed to each other, and this chain 71 rotates in a predetermined direction with power from a motor 72 that is a driving means. A plurality of, for example, four tableware baskets 3, on which a plurality of, for example, four tableware baskets 3 can be placed, are provided at a plurality of locations at equal intervals in the chain 71.

  The tableware basket support 73 has a pair of left and right rotating frames 75 that can rotate about a horizontal axis 74 with respect to the chain 71, and the tableware basket 3 mounted on the rotating frame 75. A foldable tableware basket support frame (mounting frame) 76 and a guide roller 77 that is rotatably attached to the rotating frame 75 and runs on a horizontal guide plate 80 are provided. Since the guide roller 77 runs while rotating on the guide plate 80, the tableware basket 3 on the tableware basket support frame 76 does not rotate back and forth even when the washing water b hits.

  The tableware basket support frame 76 is configured by combining a plurality of metal rod-like members, for example, like the tableware basket 3. The tableware basket support frame 76 is compared with the normal state in which the tableware basket 3 is supported only when the vicinity of the bottom of the immersion tank 21 is moved toward the inlet 26 in the immersion water a in the immersion tank 21. The folded state is low and the volume of the immersion tank 21 is suppressed (see FIG. 1).

  Next, the operation of the tableware washing apparatus 1 will be described.

  The worker, for example, puts the tableware basket 3 in the state shown in FIGS. 3 to 5 in which a plurality of tableware 2 stacked in the vertical direction is stored sideways into the immersion tank 21 from the input port 26, and the immersion tank 21. It is placed on the tableware basket support frame 76 in the immersion water a.

  At this time, there are two ways to place the tableware basket 3. That is, the first way of placing the tableware basket 3 is the tableware of the transport means 23 so that the moving direction (transport direction) of the tableware basket 3 being transported (moving) by the transport means 23 is orthogonal to the tableware stacking direction. This is a method of placing on the basket support frame 76 (see FIGS. 6 and 7). The second way of loading is to support the tableware basket 3 in the conveyance means 23 so that the movement direction (conveyance direction) of the tableware basket 3 being conveyed (moving) by the conveyance means 23 coincides with the tableware stacking direction. This is a method of placing on the frame 76 (see FIGS. 8 and 9).

  Therefore, first, the cleaning in the case of the first mounting method (see FIGS. 6 and 7) will be described.

  The plurality of tableware 2 in the tableware basket 3 which is inserted from the input port 26 and placed on the bottom of the tableware basket support frame 76 is supplied from the opening 5 of the tableware 2 and the tableware rotation injection means 31 in the immersion tank 21. The entire tableware is immersed in the immersion water a in the immersion tank 21 together with the tableware basket 3 so that the sprayed washing water b faces each other, and the tableware basket in the immersion tank 21 is moved in this immersed state. The region is moved in a predetermined movement direction (A direction in FIG. 1).

  At this time, the tableware 2 in the tableware basket 3 is washed by immersion in the immersion water a, and the deposits on the tableware 2 are removed. In addition, for example, the adhered matter firmly attached to the surface of the tableware 2 absorbs moisture and becomes softened and easily removed.

  At this time, the table rotating means 31 in the submerged water a has a washing water b on the surface orthogonal to the moving direction of the tableware basket 3 with respect to the tableware 2 in the tableware basket 3 passing above. It sprays toward the diagonally upper side substantially along. Then, a cleaning gap is generated between the adjacent dishes 2 in the tableware basket 3 in the immersion water a based on the injection of the cleaning water b, and the cleaning water b enters the gap, so that the inside of the tableware basket 3 The tableware 2 is washed, and the deposits on the tableware 2 are removed.

  Moreover, when the washing water b from the tableware rotating spray means 31 hits a portion deviated from the center of the circle of the tableware 2, the tableware 2 in the tableware basket 3 is immersed in the immersion water a based on the jetting of the washing water b. Rotating in one direction and the other direction with respect to the tableware basket 3 around the center of the circle of the circular tableware 2, and the position where the washing water b hits the tableware 2 changes, so that the deposits 2 are removed and immersed. Promoted. In addition, since buoyancy acts on the tableware 2 in the immersion water a, the tableware 2 is easily rotated in the tableware basket 3.

  And after washing | cleaning in such an immersion tank 21, the tableware basket 3 mounted on the tableware basket support frame 76 is a predetermined | prescribed moving direction (in FIG. 1, in the tableware basket movement area | region of the lower main washing chamber part 41). B direction), and then the respective tableware basket movement areas of the upper main cleaning chamber section 42 and the finishing cleaning chamber section 43 are moved in a predetermined movement direction (C direction in FIG. 1).

  At this time, the upper injection means 46 injects the curtain-like washing water b toward the tableware 2 in the tableware basket 3 vertically downward, and the lower injection means 47 applies to the tableware 2 in the tableware basket 3. Then, the washing water b is sprayed obliquely upward in the horizontal direction along a plane orthogonal to the moving direction of the tableware basket 3. Then, a cleaning gap is generated between the adjacent dishes 2 in the tableware basket 3 based on the injection of the cleaning water b, and the cleaning water b enters the gap, thereby cleaning the tableware 2 in the tableware basket 3. Is done.

  That is, as shown in FIG. 6, the horizontal dimension perpendicular to the moving direction of the curtain-like washing water b, that is, the tableware basket 3, along the tableware stacking direction from the slit-shaped injection port portion 50 of the upper injection unit 46. If the curtain-like washing water b having the width dimension of the table 2 hits all the tableware 2 in each tableware basket 3 from above, the tableware 2 other than the tableware 2 on the other end contacting the other side contact portion 17 is, for example, Until the tableware 2 at one end contacts the one-side contact portion 16, the tableware 2 horizontally moves all at once toward the space 20 side on the one-side contact portion 16 side, and separates from the adjacent tableware 2. As a result, with respect to all the dishes 2 in the tableware basket 3, a gap for cleaning is simultaneously generated between the adjacent dishes 2, and a part of the washing water b enters each of these gaps, and the washing water b that has entered enters the tableware. The deposits adhering to the front and back surfaces of 2 are removed. The size of each gap generated by the curtain-shaped washing water b is substantially equal, and is large enough for the washing water b to enter and remove the deposits on the tableware 2. Even if the gap is a slight size, if the washing water b enters, the dirt of the tableware 2 is removed by the water flow and the immersion effect.

  It should be noted that there is a cleaning gap between adjacent tableware 2 with respect to all tableware 2, but “all” here includes not only the strict meaning but also almost all the meanings. In other words, for example, because a deposit such as leftovers adheres between the adjacent tableware 2, a cleaning gap may not easily occur. In this case, a gap is generated between the adjacent dishes 2 by the washing water b from at least one of the second and subsequent upper injection means 46.

  Further, at this time, as shown in FIG. 7, when the washing water b from the upper injection means 46 hits a portion shifted from the center of the circle of the tableware 2, the cleaning gap is maintained between the adjacent tableware 2. Thus, all tableware 2 in the tableware basket 3 is mainly subjected to the force received from the curtain-like washing water b from the upper injection means 46, and the direction in which the front side of the tableware basket 3 moves downward (one direction) and the tableware basket Since the position where the curtain-like washing water b hits is changed by rotating with respect to the tableware basket 3 in the direction (the other direction) in which the rear side of the movement direction 3 is directed downward, the curtain-like washing water b is applied to the tableware 2 as a whole. It will hit efficiently and the washing | cleaning of the tableware 2 will be ensured.

  The tableware 2 in the tableware basket 3 also receives an auxiliary rotational force from the washing water b from the lower injection means 47. Further, the lower side of the gap between the adjacent dishes 2 in the tableware basket 3 tends to be narrower than the upper side by the curtain-like washing water b from the upper injection means 46, but the washing water b from the lower injection means 47 is adjacent to the upper side. By feeding to the lower side of the gap between the matching tableware 2, the lower side of the gap between the tableware 2 is prevented from being narrowed.

  In this way, the tableware 2 in the tableware basket 3 is cleaned in each of the cleaning chamber portions 41, 42, 43 in the cleaning chamber 22, and the deposits on the tableware 2 are removed. The operator lifts the tableware basket 3 after washing the tableware from the tableware basket support frame 76 and removes it from the discharge port 27.

  Next, a description will be given of the cleaning when the second mounting method is used (see FIGS. 8 and 9).

  The plurality of tableware 2 in the tableware basket 3 introduced from the input port 26 and placed on the bottom part of the tableware basket support frame 76 is immersed in the whole with the tableware basket 3 in the same manner as in the first loading method. It is immersed in the immersion water a in 21 and moves in the tableware basket movement region in the immersion tank 21 in a predetermined movement direction (direction A in FIG. 1) while being immersed.

  At this time, the tableware 2 in the tableware basket 3 is washed by immersion in the immersion water a, and the deposits on the tableware 2 are removed. In addition, for example, the adhered matter firmly attached to the surface of the tableware 2 absorbs moisture and becomes softened and easily removed.

  At this time, the table rotating means 31 in the submerged water a has a washing water b on the surface orthogonal to the moving direction of the tableware basket 3 with respect to the tableware 2 in the tableware basket 3 passing above. It sprays toward the diagonally upper side substantially along. Then, on the tableware 2 in the tableware basket 3 in the immersion water a based on the injection of the cleaning water b, a cleaning gap is generated between the adjacent tablewares 2 from the leading end side in the moving direction, and the cleaning water b is formed in the gap. , The dishes 2 in the tableware basket 3 are sequentially washed, and the deposits on the tableware 2 are removed.

  In addition, since the washing water b from the tableware rotating spray means 31 hits a portion shifted from the center of the circle of the tableware 2, the tableware 2 in the tableware basket 3 is immersed in the immersion water a based on the jetting of the washing water b. The circular tableware 2 rotates about the center of the circle in only one direction with respect to the tableware basket 3, and the position where the washing water b hits the tableware 2 is changed. The In addition, since buoyancy acts on the tableware 2 in the immersion water a, the tableware 2 is easily rotated in the tableware basket 3.

  And after washing | cleaning in such an immersion tank 21, the tableware basket 3 mounted on the tableware basket support frame 76 is a predetermined | prescribed moving direction (in FIG. 1, in the tableware basket movement area | region of the lower main washing chamber part 41). B direction), and then the respective tableware basket movement areas of the upper main cleaning chamber section 42 and the finishing cleaning chamber section 43 are moved in a predetermined movement direction (C direction in FIG. 1).

  At this time, the upper injection means 46 injects the curtain-like washing water b toward the tableware 2 in the tableware basket 3 vertically downward, and the lower injection means 47 applies to the tableware 2 in the tableware basket 3. Then, the washing water b is sprayed obliquely upward in the horizontal direction along a plane orthogonal to the moving direction of the tableware basket 3. Then, a cleaning gap is generated between the adjacent dishes 2 in the tableware basket 3 based on the injection of the cleaning water b, and the cleaning water b enters the gap, thereby cleaning the tableware 2 in the tableware basket 3. Is done.

  That is, as shown in FIG. 9, when the curtain-like washing water b along the tableware stacking direction from the slit-shaped injection port portion 50 of the upper injection means 46 hits the tableware 2 in the tableware basket 3 from above, The tableware 2 moves horizontally one by one toward the space 20 side, and leaves the adjacent tableware 2. As a result, with the movement of the tableware basket 3, a cleaning gap is sequentially generated between adjacent tableware 2 in the tableware basket 3, and a part of the cleaning water b enters the sequentially generated gap. Deposits adhering to the front and back surfaces of the tableware 2 are removed by the washing water b.

  At this time, as shown in FIG. 8, the tableware 2 in the tableware basket 3 passing above the lower injection means 47 is unidirectionally driven by the force received from the washing water b from the lower injection means 47 (FIG. 8). Among them, since the position where the washing water b is rotated by rotating with respect to the tableware basket 3 in the counterclockwise direction is changed, the curtain-like washing water b efficiently hits the tableware 2 as a whole. This ensures the cleaning.

  In this way, the tableware 2 in the tableware basket 3 is cleaned in each of the cleaning chamber portions 41, 42, 43 in the cleaning chamber 22, and the deposits on the tableware 2 are removed. The operator lifts the tableware basket 3 after washing the tableware from the tableware basket support frame 76 and removes it from the discharge port 27.

  And according to the tableware washing apparatus 1, before washing the tableware 2 in the tableware basket 3 in the washing room 22 in the case of either the first or second mounting method, The tableware 2 in the tableware basket 3 is soaked in the immersion water a to wash the tableware 2 in the tableware basket 3, so that the tableware 2 can be properly cleaned regardless of the state of the deposits attached to the tableware 2. .

  Moreover, it is arrange | positioned under the tableware basket movement area | region in the immersion tank 21, and wash water b is sprayed diagonally upward with respect to the tableware 2 in the tableware basket 3, and the immersion water in the immersion tank 21 by this injection Since the table rotating injection means 31 for rotating the tableware 2 in the tableware basket 3 in a is provided, the tableware 2 is efficiently washed by immersion in the immersion water a, and the tableware 2 can be more appropriately cleaned. .

  Furthermore, since the washing room 22 is disposed above the immersion tank 21, the overall size of the tableware washing apparatus 1 can be easily reduced without increasing the installation area of the tableware washing apparatus 1.

  Further, since the lower side of the tableware 2 overlapped in the tableware basket 3 is supported by only two parallel support rods 14, the cleaning water b in the cleaning chamber 22 and during the immersion in the immersion water a in the immersion tank 21 is also provided. During the spraying, the deposits removed from the tableware 2 are less likely to adhere to the tableware basket 3, and the deposits on the tableware basket 3 can be suppressed.

  Further, there is no need to interpose an intervening member between the adjacent dishes 2 in the tableware basket 3, for example, a plurality of stacked tableware 2 can be easily stored in the tableware basket 3, and the stacked tableware 2 can be stored in the tableware basket 3. It can be easily taken out from the inside.

  For example, although not shown, the posture of the tableware 2 in the tableware basket 3 changes depending on the type of the tableware 2 and the state of the tableware 2 when stored in the tableware basket 3. When the opening 5 changes from the inclined posture inclined with respect to the vertical plane to generate a gap between the adjacent tableware 2, when the opening 5 moves in the inclined posture and generates a gap between the tableware 2, There are cases where a gap is generated between the tableware 2 by changing from the posture to the inclined posture, and a gap is generated between the tableware 2 by changing from the one-side inclined posture to the other-side inclined posture.

  Further, the configuration is not limited to the configuration in which the cleaning chamber 22 is disposed above the immersion bath 21, and for example, the configuration in which the cleaning chamber 22 is disposed behind or on the side of the immersion bath 21 may be employed.

  Further, the cleaning chamber 22 is not limited to the two-stage one having the upper main cleaning chamber section 42 and the lower main cleaning chamber section 41, and may be one stage or three or more stages, for example.

  Further, as the immersion liquid in the immersion tank 21, it is preferable to use, for example, warm water of a predetermined temperature or higher. Further, as the cleaning liquid sprayed from the tableware rotation spraying means 31 in the immersion tank 21, for example, in the main cleaning tank 56 Washing water b may be used.

  Furthermore, the direction of the cleaning liquid (spraying liquid) sprayed from the table rotating means 31 in the immersion tank 21 and the bottom spraying means 47 in the cleaning chamber 22 is not limited to a certain diagonally upward direction. It may be possible to change the size according to the size or the cleaning state. That is, for example, the configuration may be such that the orientation of the nozzle portions 33 and 53 can be changed.

  For example, in order to prevent the tableware 2 in the tableware basket 3 from jumping out from the opening 12 on the upper surface during washing, an opening / closing lid that covers the opening 12 so as to be openable / closable may be provided on the tableware basket 3. Good.
