And an opening / closing opening 12 for taking in and out the tableware 2 with respect to the storage space 11.

  The storage space 11 which is a tableware storage section in the tableware basket 3 does not store a plurality of tableware 2 in a stationary state, but the tableware 2 is placed in the stacking direction when the tableware washing apparatus 1 cleans the tableware. A plurality of dishes 2 are stacked one on top of the other and stored, leaving a space (room) 13 for movement.

  At this time, as for several tableware 2, the surface (inner surface) of one tableware 2 of the tableware 2 adjacent to each other, and the back surface (outer surface) of the other tableware 2 do not go through an interposition member (conventional holding member etc.). Are stacked and stored in a state of being in contact with each other and facing each other.

  In addition, when the surface of one tableware 2 and the back surface of the other tableware 2 here contact each other, the surface and the back surface are substantially in contact with each other in addition to the case where the surface and the back surface are in a strict sense. Cases are also included. That is, for example, there is a case where an adhering substance that is a dirt adhering to the tableware 2 between the adjacent tableware 2, that is, a residue such as, for example, leftover rice or residual juice, and the front surface and the back surface are slightly separated.

  As shown in FIG. 5, the tableware basket 3 includes an upper restricting portion (one-side restricting portion) 16 disposed on the upper surface of the storage space portion 11. The upper restricting portion 16 includes, for example, an upper restricting rod 17 in the left and right longitudinal direction that is bent at a plurality of locations, an upper restricting rod 18 in the straight left and right longitudinal shape that is not bent, An upper connecting rod 19 that connects the central portions of the regulating rods 17 and 18 is provided. A moving space 13 exists between the upper restricting portion 16 and the tableware 2 at the upper end.

  Furthermore, the tableware basket 3 is disposed on the lower surface of the storage space portion 11, and is a lower restricting portion that supports the plurality of tableware 2 that are stored in the storage space portion 11 in contact with each other and stacked vertically. The other side restricting part) 21 is provided. The lower restricting portion 21 has, for example, a plurality of (for example, three) lower restricting rods 22 that are longitudinal in the front-rear direction.

  The tableware basket 3 is disposed on the front surface of the storage space portion 11, and before the forward movement of the plurality of tableware 2 stored in the storage space portion 11 in contact with each other and stacked vertically is stored. A regulation unit 23 is provided. The front restricting portion 23 has, for example, two front restricting rods 24 in a pair of left and right elongated in the vertical direction.

  Further, the tableware basket 3 is disposed on the rear surface of the storage space portion 11, and is configured to restrict rearward movement of the plurality of tableware 2 stored in the storage space portion 11 so as to contact each other and be stacked in the vertical direction.

In addition, the outer peripheral part of each rear regulating rod 27 having a round bar shape with a circular cross section is formed of, for example, a resin having a small coefficient of friction with the tableware 2.

  At the time of dishwashing by the dishwashing apparatus 1, the tableware basket 3 is moved from the normal posture state of FIG. 5 to the washing posture state rotated 90 degrees so that the front regulating portion 23 is located on the upper side as shown in FIG. The posture is changed.

  In the cleaning posture state of FIG. 6, the rear restricting portion 26, which is a support rod portion, contacts the storage space portion 11 with each other, and the peripheral end portions of the plurality of tableware 2 stored in the horizontal direction are placed in the tabletop stacking direction. It is movably supported from below. At this time, at least a part of the plurality of tableware 2 is inclined with respect to the vertical direction so as to lean against the adjacent tableware 2 based on its own weight (an inclined posture in which the opening surface 4 faces obliquely upward). It becomes.

  Further, in this cleaning posture state, the upper restricting portion 16 contacts the storage space portion 11 and comes into contact with the surface of the tableware 2 at one end of the plurality of tableware 2 stored in the horizontal direction. Thus, the movement of the tableware 2 in one direction (the movement direction of the tableware basket 3) is restricted. Similarly, the lower restricting portion 21 is brought into contact with the storage space portion 11 so as to come into contact with the back surface of the tableware 2 at the other end of the plurality of tableware 2 stored in the horizontal direction. The movement in the other direction (the anti-movement direction of the tableware basket 3) is restricted.

  Furthermore, in this cleaning posture state, the tableware 2 at the other end receives the weight of the other tableware 2 and is in contact with the lower restricting portion 21. For example, the tableware 2 at one end has its opening surface 4 obliquely upward. The table in the tableware basket 3 is not between the tableware 2 on the one end and the upper control unit 16 at the time of tableware washing. 2 has a space 13 for movement on the rear restricting portion 26, and the tableware 2 is unstable in the tableware stacking direction in the tableware basket 3 (movable in the tableware stacking direction, and has an inclined posture and a vertical posture. The posture can be changed between

  Depending on the shape of the tableware 2, for example, when only the lower part of the tableware 2 that is inclined in the tableware basket 3 is in contact with the upper restricting portion 16, Of course, all tableware 2 may be stored in a vertical posture.

  As shown in FIGS. 1 and 2, the tableware washing apparatus 1 includes a tableware basket 3 in a cleaning posture state in which a plurality of tablewares 2 are in contact with each other without interposition of members and are stored in a horizontal direction. The table includes a transport means 31 such as a bar conveyor that moves the table 2 in the moving direction along the tabletop stacking direction with the opening surface 4 of the tableware 2 facing the moving direction.

  The conveyance means 31 has a pair of left and right endless bodies 33 that rotate in a predetermined direction based on power from a drive source 32 such as a motor. The endless bodies 33 are connected to the drive rotating body 34 and the driven rotating body 35. It is being handed over. Between both endless bodies 33, a plurality of round bar-shaped transport rods 36 on which the tableware basket 3 containing the tableware 2 is placed and moved in the transporting direction, which is the transporting direction, are equidistantly spaced in the direction of endless body circulation. It is erected. Each tableware basket 3 is transported in a state of being placed on a plurality of (for example, four) transport rods 36.

  Moreover, the tableware washing apparatus 1 is arrange | positioned above the movement area | region where the tableware basket 3 moves, and injects the wash water W downward toward the tableware 2 in the tableware basket 3 from the downward upward injection port part 41a. A plurality of lower nozzles 41 are disposed below the moving region in which the tableware basket 3 moves, and sprays the washing water W upward from the upward lower injection port portion 42a toward the tableware 2 in the tableware basket 3. Nozzle 42.

  Each upper nozzle 41 is a rectangular tube having a longitudinal direction in the horizontal direction perpendicular to the moving direction of the tableware basket 3, and a cylindrical portion 45 to which cleaning water W is supplied therein, and a lower surface of the cylindrical portion 45. And a single horizontally long nozzle portion 46 that is positioned over substantially the entire length of the cylindrical portion 45. An upper injection port 41a, which is a slit-like water outlet having a longitudinal direction in the horizontal direction orthogonal to the moving direction of the tableware basket 3, is formed on the tip surface of the nozzle unit 46. The upper injection port 41a The curtain-like washing water W is jetted from the outside. Note that the length in the longitudinal direction of the upper injection port portion 41a is substantially the same as the width of the conveying means 31.

  Each lower nozzle 42 has a cylindrical shape having a longitudinal direction in a horizontal direction perpendicular to the moving direction of the tableware basket 3 and a cleaning portion W supplied with cleaning water W therein, and this cylindrical portion. A plurality of nozzle portions 48 that protrude from the outer peripheral surface of the cylindrical portion 47 and are arranged at intervals in the longitudinal direction of the cylindrical portion 47 are provided. A circular lower injection port portion 42 a for injecting the linear cleaning water W is formed on the tip surface of each nozzle portion 48. That is, the linear wash water W is sprayed from the plurality of lower spray ports 42a arranged at intervals in the horizontal direction orthogonal to the moving direction of the tableware basket 3, respectively. The lower nozzle 42 is disposed between the transport rod 36 on the forward path side and the transport rod 36 on the return path side.

  Furthermore, the tableware washing apparatus 1 includes a plurality of pumps 52 that suck in the washing water W in the tank 51 and pump it. One upper nozzle 41 and one lower nozzle 42 are connected to each connecting pipe 53 connected to each pump 52, and the lower nozzle 42 is slightly shifted from the position directly below the upper nozzle 41 toward the moving direction of the tableware basket 3. It is arranged at the position. That is, the plurality of upper nozzles 41 and the lower nozzles 42 are all arranged in parallel with each other in the moving direction of the tableware basket 3, but the lower nozzle 42 is supplied with the washing water W from the same connection pipe 53. The table is disposed at a position shifted from the position just below the corresponding upper nozzle 41 by a predetermined distance toward the moving direction of the tableware basket 3.

  The tableware washing apparatus 1 also includes a washing chamber 55 for washing the tableware 2 in the tableware basket 3 with the washing water W sprayed from the upper and lower nozzles 41 and 42. The cleaning chamber 55 is constituted by, for example, a rough cleaning chamber portion 56, an intermediate cleaning chamber portion 57, and a finishing cleaning chamber portion 58. When the tableware basket 3 moves in the three cleaning chamber portions 56, 57, 58, the tableware The tableware 2 in the basket 3 is washed with washing water W from the upper and lower nozzles 41 and 42.

  In the rough cleaning chamber 56, a plurality of, for example, three upper nozzles 41 are disposed at the upper portion thereof, and the same number of lower nozzles 42 are disposed at the lower portion thereof. The intermediate cleaning chamber 57 is also provided with a plurality of, for example, three upper nozzles 41 at the upper portion thereof, and the same number of lower nozzles 42 at the lower portion thereof. A plurality of, for example, two upper nozzles 41 are disposed in the upper portion of the finishing cleaning chamber 58, and the same number of lower nozzles 42 are disposed in the lower portion thereof. The number of nozzles 41 and 42 in each of the cleaning chambers 56, 57, and 58 is not limited to this and is arbitrary.

  Here, as shown in FIGS. 1 and 2, the plurality of upper nozzles 41 arranged at intervals in the moving direction of the tableware basket 3 in the upper part in the cleaning chamber 55 are all in the same direction according to the type of the tableware 2. Is directed to. In other words, the direction of the upper injection port 41a of all the upper nozzles 41 in the cleaning chamber 55 is such that the washing water W flows smoothly between the adjacent tablewares 2 (the shape of the tableware 2). Etc.) is set in a certain direction.

  In other words, the spraying direction of the cleaning water W sprayed downward from each upper nozzle 41 (the opening direction of the upper spraying port 41a) is on the opposite side of the tableware basket 3 to the vertical direction (the moving direction rear side). All are inclined at the same inclination angle α.

  The inclination angle (inclination angle of the upper nozzle 41) α with respect to the vertical downward direction of the spray direction of the washing water W is set to “10 degrees or less not including 0 degrees” so that it can correspond to any tableware 2, and more preferably. For example, in the example shown in FIG. 2, it is possible to cope with many commonly used tableware 2. For example, in the example shown in FIG. The angle is set to 5 degrees.

  Further, unlike the upper nozzle 41, the plurality of lower nozzles 42 arranged at intervals in the moving direction of the tableware basket 3 at the lower part in the cleaning chamber 55 are directed in a plurality of directions.

  In other words, the direction in which the cleaning water W is sprayed upward from the lower nozzle 42 of the plurality of lower nozzles 42, that is, the first lower nozzle 42 of each of the cleaning chambers 56, 57, 58, for example (lower injection port). The opening direction of the portion 42a is inclined at a first inclination angle β1 toward the counter-moving direction side (the moving direction rear side) of the tableware basket 3 with respect to the vertical direction. The spraying direction of the cleaning water W sprayed upward from the lower nozzle 42, that is, the second lower nozzle 42 of each of the cleaning chambers 56, 57, 58, for example, is on the side opposite to the vertical direction of the tableware basket 3 From the other lower nozzle 42 of the plurality of lower nozzles 42, that is, from the third lower nozzle 42 of the rough cleaning chamber portion 56 and the intermediate cleaning chamber portion 57, for example. The spraying direction of the cleaning water W sprayed upward is that of the tableware basket 3 with respect to the vertical direction. It inclines with the 3rd inclination-angle (beta) 3 toward the anti-movement direction side.

  Note that the inclination angles (inclination angles of the lower nozzle 42) β1, β2, and β3 with respect to the vertical upward direction of the washing water W injection direction are different from each other. For example, in the example shown in FIG. β2 is set to 40 degrees and β3 is set to 20 degrees. The inclination angle of each lower nozzle 42 can be individually adjusted within a range of 0 to 45 degrees, for example.

  Moreover, the spraying pressure of the wash water W sprayed downward from the upper nozzle 41a of the upper nozzle 41 separates the tableware 2 adjacent to each other by separating the entire tableware 2 adjacent to each other. The size is set such that a gap in the form of an opening on both the upper and lower sides is generated between the entire tableware 2. The spray pressure of the cleaning water W from each upper nozzle 41 is all constant (including substantially constant).

  On the other hand, the spraying pressure of the washing water W sprayed upward from the lower nozzle part 42a of the lower nozzle 42 does not completely separate the adjacent tablewares 2 that are in contact with each other, and the upper parts of the adjacent tablewares 2 are separated. Instead, it is set to such a size that only a lower part is separated to create a downward opening-like gap only between the lower parts of the tableware 2 adjacent to each other. Note that the spray pressure of the cleaning water W from each lower nozzle 42 is all constant (including substantially constant).

  Next, a dish washing method for washing dishes using the tableware washing apparatus 1 will be described.

  The worker rotates the tableware basket 3 in the normal posture state in which a plurality of tableware 2 of the same type to which the adhering matter is attached is stored in a stacked manner and rotates them 90 degrees to the washing posture state, and then the dishwasher 1 Are sequentially put into the cleaning chamber 55.

  The tableware basket 3 in the cleaning posture put into the cleaning chamber 55 is placed on the plurality of transport bars 36 of the transport means 31 and is transported by the plurality of transport bars 36. The

  That is, as shown in FIG. 3 (a), the tableware basket 3 in which a plurality of tablewares 2 are in contact with each other and stored in a horizontal direction is moved along the opening surface 4 of the tableware 2 in the tableware basket 3. It is moved in the moving direction along the tabletop stacking direction.

  And as shown in FIG.3 (b), the upper injection port part 41a of the upper nozzle 41 in the direction match | combined with the tableware 2 in the tableware basket 3 currently moving to the moving direction by the conveyance means 31 according to the kind of tableware 2 is shown. By applying the washing water W from above from the upper side, the entire tableware 2 adjacent to each other is separated to create a gap in the form of both upper and lower openings between the entire tableware 2 adjacent to each other. The washing water W is introduced from above, and the entered washing water W flows from the top to the bottom in the gap so that the deposits of the tableware 2 are washed down to wash the tableware 2.

  In other words, the tableware 2 is sequentially moved one by one by the cleaning water W from the upper nozzle 41 to form a gap in the form of both upper and lower openings between the adjacent tableware 2, and the cleaning water W enters the gap to set the tableware. Remove the deposit (dirt) of 2. The tableware 2 washed by the upper nozzle 41 has an inclined posture inclined with respect to the vertical direction so that the opening surface 4 faces obliquely downward in the tableware basket 3.

  Thereafter, as shown in FIG. 3 (c), the lower nozzle 42 is placed on the tableware 2 in the tableware basket 3 being moved in the movement direction by the conveying means 31 at a position ahead of the upper nozzle 41 in the movement direction. The upper part of the tableware 2 adjacent to each other is kept in contact with each other by applying the washing water W from the lower jetting port portion 42a from the lower side (that is, one tableware 2 on the front side in the moving direction is connected to the other table on the rear side in the moving direction). The tableware 2 is tilted in a leaning position with the upper surface of one tableware 2 and the upper surface of the other tableware 2 in contact with each other), and by separating only the lower portions of the tableware 2 adjacent to each other. A gap having a lower opening is formed only between the lower parts of the adjacent dishes 2, and the cleaning water W enters the generated gap from below, and is sandwiched between the lower parts of the adjacent dishes 2 by the inserted cleaning water W. Flow the remaining deposits downward Dropped by washing the dishes 2.

  That is, the cleaning water W from the lower nozzle 42 changes the posture of the tableware 2 one by one from the inclined posture (the inclined posture in which the opening surface 4 faces obliquely downward) to the vertical posture, and between the lower portions of the adjacent tableware 2 In the lower opening, a large gap is formed on the lower end side, and the washing water W is introduced into the generated gap from below, so that the upper nozzle 41 stays between the lower parts of the adjacent dishes 2 during washing. Remove the kimono.

  At the same time, the blind spot portion of the cleaning by the upper nozzle 41 is cleaned by the cleaning water W from the lower nozzle 42, and the vicinity of the lower portion of the tableware 2 is cleaned, for example, the deposits caught on the support rod 27 of the tableware basket 3 etc. Remove.

  Further, as shown by the solid line in FIG. 4, for example, when the cleaning water W from the first lower nozzle 42 of the rough cleaning chamber 56 hits the transport rod 36, the cleaning water W from the first lower nozzle 42. Therefore, it is not possible to generate a gap between the lower part of the back surface of the first tableware 2 and the lower surface of the next tableware 2.

  However, as indicated by a two-dot chain line in FIG. 4, for example, the cleaning water W from the second lower nozzle 42 of the rough cleaning chamber 56 is sprayed of the cleaning water W from the first lower nozzle 42 in the injection direction. Since it is different from the direction, it does not hit the transport bar 36 but passes between the transport bars 36 adjacent to each other and hits the lower part of the leading tableware 2. As a result, the wash water W from the second lower nozzle 42 creates a downward opening-like gap between the lower back surface of the leading tableware 2 and the lower surface of the next tableware 2, and this generated gap Washing water W enters and the tableware 2 is washed.

  In this way, the tableware 2 in the tableware basket 3 is sequentially cleaned by the cleaning water W from the upper and lower nozzles 41 and 42 in the rough cleaning chamber 56, and then from the upper and lower nozzles 41 and 42 in the intermediate cleaning chamber 57. The tableware 2 in the tableware basket 3 is sequentially cleaned by the cleaning water W, and then the tableware 2 in the tableware basket 3 is sequentially cleaned by the cleaning water W from the upper and lower nozzles 41 and 42 in the finishing cleaning chamber 58. The cleaning operation of the tableware 2 is completed, and the tableware basket 3 that has completed the cleaning operation is discharged out of the cleaning chamber 55 of the tableware cleaning device 1.

  According to such a tableware washing method, the tableware basket 3 in which a plurality of tableware 2 of the same type are stacked and stored is moved in the moving direction along the tableware stacking direction, and the inside of the tableware basket 3 being moved In order to wash the dishes by creating gaps between the adjacent dishes 2 by applying washing water W from a plurality of upper nozzles 41 directed to the same direction in accordance with the type of the dishes 2, An appropriate amount of washing water W can flow into the gap formed between the adjacent tableware 2, an appropriate immersion effect can be realized, and a plurality of tableware 2 can be efficiently cleaned while being stored in the tableware basket 3.

  Moreover, since the injection direction of the wash water W from each upper nozzle 41 is inclined with the same inclination angle α toward the counter-movement direction side of the tableware basket 3 with respect to the vertical direction, the tableware 2 and the tableware adjacent to each other. It is easy to separate the two, and the cleaning water W easily flows into the separated gap, so that the plurality of dishes 2 can be washed more efficiently.

  Furthermore, after washing | cleaning the tableware 2 by making the water 2 from the upper nozzle 41 apply the washing | cleaning water W from the upper nozzle 41 to the tableware 2 in the tableware basket 3 which is moving, the gap | interval of both upper and lower openings was produced. In order to clean the tableware 2 by causing the cleaning water W from the lower nozzle 42 to be applied to the tableware 2 in the tableware basket 3 that is moving, a gap between the lower portions of the tableware 2 adjacent to each other is generated. In the unlikely event that there is an adhering matter that cannot be washed away by the washing water W from the upper nozzle 41 and is sandwiched between the lower parts of the adjacent dishes 2, the adhering matter can be removed appropriately and sprayed from the upper nozzle 41. The washing water W from the lower nozzle 42 is sprayed also near the lower part of the tableware 2 that is difficult to wash with the washed water W that has been washed, and the entire tableware is washed. In the tableware basket 3 It can be cleaned efficiently as it is.

  The tableware 2 that is the object to be cleaned is not limited to a circular dish, and may be, for example, a circular bowl or tray, or may be a polygonal dish, bowl, or tray. Then, the inclination angle α of the upper nozzle 41 is set in accordance with the type of the tableware 2.

  Further, the upper injection port portion 41a of the upper nozzle 41 is not limited to a slit-like long hole portion for injecting the curtain-like cleaning water W, and for example, a circular shape for injecting the linear cleaning water W Things may be used.

  Further, for example, an angle adjusting means that can adjust the inclination angles of all the plurality of upper nozzles 41 may be provided. Note that all the plurality of upper nozzles 41 may be directed vertically downward.

  Further, the lower nozzle 42 is not necessarily required, and the cleaning may be performed only with the cleaning water W from the plurality of upper nozzles 41 facing in the same direction according to the type of the tableware 2.

  In addition, depending on the shape of the tableware 2 stacked and stored on the tableware basket 3, when the tableware basket 3 is in the cleaning posture state, the tableware stacking direction of the plurality of tableware 2 is not the horizontal direction but the front-rear direction (the horizontal movement direction). The support rod (rear regulating rod) 27 supporting the peripheral edge of the tableware 2 is attached with the longitudinal direction inclined with respect to the basket body 3a of the tableware basket 3 so that the inclination direction is inclined with respect to You may make it (refer Fig.7 (a)). That is, in the tableware basket 3 shown in FIG. 7A, the support rod 27 is positioned in a front, rear, and lower slope shape that gradually rises upward toward the front of the tableware basket 3 in the cleaning posture state. It is like that.

  In this way, by tilting the support rod 27 of the tableware basket 3 in the longitudinal direction according to the type of the tableware 2, the direction of the upper nozzle 41 a of the upper nozzle 41 (inclination angle of the upper nozzle 41) can be changed. It is possible to obtain the same effect as setting in a certain direction according to the type.

  Further, by attaching the support rod 27 to the tableware basket 3 so that the inclination in the longitudinal direction can be adjusted, even if the types of the tableware 2 to be cleaned increase, the support rods 27 are arranged in the respective cleaning chambers of the tableware cleaning apparatus 1. It is possible to suppress the setting of the inclination angle of the upper nozzle 41 according to the type of the tableware 2 as much as possible.

  In addition, when the tableware basket 3 is placed on the horizontal transfer surface of the transfer means 31, the basket body 3a of the tableware basket 3 in the cleaning posture is formed to be inclined with respect to the longitudinal direction of the support rod 27, and a plurality of The tableware stacking direction of the tableware 2 may be an inclined direction inclined with respect to the front-rear direction (horizontal movement direction) instead of the horizontal direction (see FIG. 7B).
