Here, the type of detergent can be changed by touching the icons “1” to “7” in the selection column corresponding to the detergent it on the detergent setting screen 94. Similarly, when each item of the bleach type (for example, the “chi” portion of the bleach type of the fourth main cleaning section shown in FIG. 6) is touched, a bleach setting screen 95 is displayed, and the bleach setting screen 95 is displayed. A plurality of detergent bottles are displayed. Here, the type of the bleaching agent can be changed by touching any one of the icons “1” to “3” in the selection column corresponding to the detergent chain on the bleaching agent setting screen 95.

  Furthermore, when the part of the third screen 93 corresponding to the set temperature of the cleaning water, the cleaning water, the concentration of the bleaching agent, and the conveyor speed is touched, a numeric keypad (not shown) is displayed. Washing conditions for water, bleach concentration and conveyor speed can be changed.

  After performing such a change operation, when the “confirm” icon on the third screen 93 is touched, the changed condition is input to a condition setting unit 32A (described later) of the control unit 32 (see FIG. 4). As a result, the preset cleaning conditions are changed (updated), and the third screen 93 is switched to the second screen 92. On the other hand, when the “return” icon is touched, even if the cleaning condition or the like is changed, the cleaning condition is not reflected and the screen is switched to the second screen 92.

  Finally, returning to the first screen 91, when one of the plurality of cleaning modes A to E on the first screen 91 is selected and touched by the operator, the signal of the selected cleaning mode is It is output to the control unit 32.

6). About Control Unit 32 The control unit 32 mainly includes a CPU, a memory, an AD converter, and a DA converter as hardware (not shown). Here, the CPU selects a cleaning condition corresponding to each cleaning mode, and controls the deviation of each parameter in order to feedback-control the temperature of the cleaning water and the concentration of the detergent so as to satisfy the selected cleaning condition. Output a signal. That is, in the CPU, processing of a condition selection unit 32B and control execution unit 32C, which are software described later, is performed. The memory stores cleaning conditions corresponding to each cleaning mode, and is associated with a condition setting unit 32A as software.

  As shown in FIG. 4, the control unit 32 includes a condition setting unit 32A, a condition selection unit 32B, and a control execution unit 32C as software. The condition setting unit 32A sets a plurality of different cleaning conditions according to the plurality of cleaning modes A to E. Specifically, in the condition setting unit 32A, the cleaning water w2 to w6 is associated with the cleaning modes A to E so that the stains attached to the tableware P can be effectively washed away by the menu or ingredients used for the tableware P. The cleaning conditions of the set temperatures T1 to T5, the types of detergents and bleaches, and the set concentrations D1 to D4 of the detergents and bleaches are set. In the present embodiment, a rinsing agent may be used instead of the detergent / bleaching agent in the washing water w6 of the rinsing washing unit.

  For example, in the present embodiment, the condition setting unit 32A, as shown in FIG. 7, in the case of the cleaning mode A, for example, a set temperature (T1 = a1, T2 = suitable for cleaning dishes used in meat dishes). b1,...), detergents (I, B), bleach (H), their concentrations (D1 = f1, D2 = g1,...), and conveyor speed (not shown). Similarly, in the case of the cleaning mode B, the condition setting unit 32A, for example, a set temperature (T1 = a2, T2 = b2,...) Suitable for cleaning the tableware P used in egg dishes, a detergent (I, (B, c) Bleaching agent (Li), its concentration (D1 = f2, D2 = g2,...) And conveyor speed (not shown) are set. In the other cleaning modes C to E, the condition setting unit 32A has cleaning conditions suitable for cleaning the tableware P used in each dish. As described above, the condition setting unit 32 </ b> A matches the cleaning modes A to E with the set temperature, the detergent / bleaching agent, the concentration, and the conveyor speed (conveyor speed) suitable for cleaning the tableware P used in the dish. Is set. Hereinafter, “detergent / bleaching agent” is collectively referred to as “detergent”.

  Here, data such as cleaning conditions regarding the respective cleaning modes A to E set by the condition setting unit 32 </ b> A is also output to the input unit 31 in accordance with the operation of the input unit 31 using the touch panel described above. Further, as described above, these data are rewritten by changing the cleaning condition by the input unit 31.

  Based on the cleaning mode signal input from the input unit 31, the condition selection unit 32B is input from the plurality of cleaning conditions corresponding to the plurality of cleaning modes A to E set by the condition setting unit 32A. Select cleaning conditions according to the conditions. For example, when the cleaning mode A is selected on the first screen 91 of the input unit 31 shown in FIG. 5, the cleaning conditions corresponding to the plurality of cleaning modes shown in FIG. Select cleaning conditions.

  The control execution unit 32C sets the cleaning water w2 to w6 of the first to fourth main cleaning units 12 to 15 and the rinsing cleaning unit 16 so as to be the set temperature of the cleaning water of the cleaning condition selected by the condition selection unit 32B. Control the temperature. At the same time, the control execution unit 32C selects the detergent having the cleaning condition selected by the condition selection unit 32B, and sets the concentration of the detergent contained in the cleaning water w2 to w5 of the first to fourth main cleaning units 12 to 15. Control. Further, the control execution unit 32C controls the conveyor 20 (specifically, the drive motor 25) so as to achieve the conveyor speed set in the cleaning condition.

  More specifically, the control execution unit 32C outputs a control signal to each heating device 53 so that the temperature of the washing water w2 to w6 measured by each temperature measuring device 54 becomes the set temperature T1 to T5. . For example, when the heating device 53 is a heating resistor that generates heat by energization, the temperature of the heating by the heating device 53 is controlled by controlling the value of the current supplied to the heating device 53. Thereby, the temperature of the washing water w2 to w6 can be controlled. Further, in order to lower the temperature of the cleaning water w2 to w6, water having a temperature lower than that of the cleaning water may be supplied by the control execution unit 32C.

  On the other hand, the control execution unit 32C selects the detergent having the cleaning condition selected by the condition selection unit 32B from a plurality of detergents, and controls the concentration of the selected detergent so that this becomes the set concentration. In the present embodiment, the operation of the detergent supply device 52 is controlled so that the detergent having the cleaning condition selected from the plurality of detergent supply devices 52 containing different detergents is supplied to the cleaning water in the storage tank 51. At this time, the control execution part 32C is the detergent supplied from the detergent supply device 52 so that the concentration of the detergent contained in the washing water w2 to w5 measured by each concentration measuring device 55 becomes the set concentration D1 to D4. (For example, the opening degree of the supply valve is controlled). Further, in order to reduce the concentration of the detergent contained in the cleaning water w2 to w5, for example, the cleaning water w6 or clean water of the rinsing cleaning unit 16 may be supplied to the cleaning water w2 to w5 by the control execution unit 32C.

  In this embodiment, a plurality of detergent supply devices 52 containing different detergents are provided. However, a plurality of detergent supply devices 52 containing the same detergent are provided, and depending on the number of operating detergent supply devices 52, the detergent supply devices. The supply amount (detergent concentration) of the detergent supplied from 52 may be controlled.

7). About the usage method of the tableware washing apparatus 1 Below, the usage method of the tableware washing apparatus 1 mentioned above is demonstrated.
The used tableware is washed in a state of being stored in the tableware basket 70 shown in FIGS. The tableware basket 70 is, for example, a rectangular parallelepiped wire mesh basket configured by combining a plurality of bar members, and is used in the normal posture state of FIGS. As shown in FIG. 8B, the tableware is used in a cleaning posture state in which dishes are stacked upward as shown in FIG. 8B (a state in which the front surface is rotated 90 degrees from the normal posture state to the upper surface). At the time of dishwashing by the dishwashing apparatus 1, the tableware basket 70 is put into the dishwashing apparatus 1 in the cleaning posture state of FIG. 8B, and the use surface of the tableware P in the tableware basket 70 is in the transport direction M. Are conveyed along a conveying direction M along the stacking direction of the tableware.

  As shown in FIG. 8 (b), the tableware basket 70 includes a plurality of frames 72 so that an accommodation space 71 for accommodating the stacked tableware P is formed. Further, on the frame body 72 of the tableware basket 70, as shown in FIG. 8A, three support members 73 that support the bottom of the tableware P stacked in the normal posture state, as shown in FIG. 8B. In addition, a pair of support members 77 and 77 for supporting the tableware P stacked in a cleaning posture while being positioned are attached. Furthermore, restricting members 74 and 75 for restricting the movement of the tableware are attached so that the tableware P stacked in the accommodation space 71 is accommodated.

  Here, the worker who cleans the tableware P first confirms what menu or food is used for the tableware P accommodated in the tableware basket 70. Next, the operator can select one cleaning mode from the plurality of cleaning modes A to E at the input unit 31 according to the menu or food of the plurality of dishes to be cleaned. For example, when the menu is meat dishes and the ingredients are pig meat or beef, the “cleaning mode A” icon of the input unit 31 is touched to select the cleaning mode A.

  In addition, when confirming the cleaning contents of the cleaning mode A, the “detailed confirmation” of the first screen 91 shown in FIG. 5 is touched to switch to the second screen 92, not only the cleaning conditions of the cleaning mode A, Menus and ingredients suitable for the cleaning mode A can be confirmed. The change of the cleaning condition in the cleaning mode A is as described above.

  When the cleaning mode is selected by the input unit 31, a signal of the selected cleaning mode is input from the input unit 31 to the condition selection unit 32B of the control unit 32. Based on the cleaning mode signal input from the input unit 31, the condition selection unit 32B selects a cleaning condition corresponding to the input cleaning mode from the plurality of cleaning conditions of the condition setting unit 32A. The control execution unit 32C selects a detergent having the cleaning condition selected by the condition selection unit 32B, and outputs a control signal for controlling the temperature of the cleaning water and the concentration of the detergent so that the cleaning water has the preset temperature and the detergent concentration. Output. A specific control method by the control execution unit 32C is as described above.

  As a result of this, the operator only needs to select one cleaning mode from the input unit 31 in accordance with the state of dirt on the tableware, so that the cleaning water controlled to the optimal cleaning temperature and optimal detergent concentration can be obtained. , Can be sprayed on the tableware P being conveyed. Thereby, the stain | pollution | contamination adhering to tableware can be washed away easily. In particular, in the present embodiment, the temperature of the cleaning water w2 to w5 and the concentration of the detergent can be controlled according to the cleaning pattern for each of the first to fourth main cleaning units 12 to 15, so that finer cleaning is performed. Tableware can be washed under conditions.

  Here, in this embodiment, in the 1st-4th main washing | cleaning parts 12-15, the wash water w2-w5 sprayed on the tableware is collect | recovered in the storage tank 51, and the collect | recovered wash water is used for the conveyed tableware. Sequentially sprayed and reused cleaning water w2 to w5. When performing such washing, the washing ability decreases when a large amount of a plurality of types of soil components adhering to the tableware P are mixed in the washing water w2 to w5, and the concentration of the detergent contained in the washing water w2 to w5 is reduced. Even if it is controlled, the cleaning effect by the detergent may not be sufficiently exhibited.

  However, in this embodiment, before the tableware P passes through the first to fourth main cleaning units 12 to 15, the rough cleaning unit 11 can preliminarily wash the tableware and remove the deposits. The dirt adhering to the tableware P conveyed to the 1st-4th main washing | cleaning parts 12-15 is reduced. Thereby, even if it reuses the wash water of the 1st-4th main washing | cleaning parts 12-15, it suppresses that the stain | pollution | contamination component of tableware P mixes abundantly into washing water w2-w5, and the 1st-4th. In the main cleaning sections 12 to 15, the cleaning effect by the detergent whose concentration is controlled can be effectively exhibited.

  In particular, in the present embodiment, since the rough cleaning unit 11 is provided with a device for collecting the dust (residue) attached to the tableware P, the cleaning water w1 to be reused is cleaned, and the tableware P is reattached with dirt. Can be prevented. Thereby, in the 1st-4th main washing | cleaning parts 12-15, the washing | cleaning effect by the detergent by which density control was carried out can be exhibited further.

  In the present embodiment, the condition setting unit 32A sets the detergent to be supplied to the washing waters w2 to w5 among the plurality of types of detergents and bleaches for each of the plurality of washing modes. When a detergent that is one of the cleaning conditions selected and input by the input unit 31 is selected by the condition selection unit 32B, the detergent selected by the control execution unit 32C from the plurality of detergents is selected by the control execution unit 32C. The concentration of the selected detergent can be controlled so that the concentration becomes a preset concentration. As a result, the tableware P is washed using the washing waters w2 to w5 adjusted (controlled) so that an appropriate type of detergent has a set concentration only by selecting the washing mode at the input unit 31. Can do.

  Here, for example, in the condition setting unit 32A, among the first to fourth main cleaning units 12 to 15, the cleaning conditions of some adjacent main cleaning units (for example, the first and second main cleaning units 12 and 13). May be set to the same cleaning conditions. Accordingly, the tableware P is transported to the adjacent main cleaning units (first and second main cleaning units 12 and 13) set to the same cleaning conditions, thereby substantially reducing the transport speed of the transport unit. In addition, the cleaning time for cleaning under the cleaning conditions can be extended.

  Further, in the condition setting unit 32A, among the first to fourth main cleaning units 12 to 15, in some adjacent main cleaning units (for example, the second and third main cleaning units 13 and 14), The temperature of the cleaning water (w4) of the downstream main cleaning unit (third main cleaning unit 14) is higher than the temperature of the cleaning water (w3) of the upstream main cleaning unit (second main cleaning unit 13). As described above, the set temperature of the cleaning condition may be set.

  Thereby, in the main washing part (second main washing part 13) on the upstream side in the transport direction M, the relatively large dirt and protein adhering to the tableware P are washed away with the washing water (w3) having a relatively low temperature. In the main cleaning section (the third main cleaning section 14) on the downstream side, since the temperature of the cleaning water (w4) is increased, dirt such as oil and fat adhering to the tableware P can be washed away.

  When the tableware P is washed, as shown in FIG. 9A, the tableware basket 70 in which a plurality of tableware P is stacked by the conveyor 20 is used by the table 20 in the tableware basket 70. Is transported in the transport direction M toward the tableware transport direction M.

  Here, the cleaning water w1 to w6 (see FIG. 9B) from the upper cleaning nozzle 41 of the rough cleaning unit 11, the first to fourth main cleaning units 12 to 15 and the rinse cleaning unit 16, and the finish cleaning The washing water w7 from the upper washing nozzle 81 of the unit 17 is sprayed from the upper side to the stacked tableware P being conveyed. A gap is sequentially formed between the upper portions of the tableware P, P in the tableware basket 70 being conveyed in the conveyance direction M by the spraying pressure of the washing water w1 to w7, and the washing water w1 to w7 is formed in the gap. Enters. Thereby, the tableware is washed one by one.

  Thereafter, the cleaning waters w1 to w6 (see FIG. 9C) from the lower cleaning nozzles 42 of the first to fourth main cleaning units 12 to 15 and the rinse cleaning unit 16, and the bottom cleaning unit 17 The washing water w7 from the side washing nozzle 82 is sprayed from the lower side to the stacked tableware P being conveyed. Thereby, with the spraying pressure of the washing waters w1 to w7, a gap is sequentially formed between the lower portions of the tableware P, P in the stacked state in the tableware basket 70 being transferred in the transfer direction M, and the tableware P, P Washing water and deposits accumulated at the lower part of each other can be removed.

  In the cleaning using the tableware basket 70 described above, the tableware P is cleaned with a small amount of the cleaning water w1 to w7 flowing into the gap between the tableware P and P, so the temperature of the cleaning water w2 to w6 and the cleaning water w2 Cleaning efficiency greatly depends on the detergent added to w5 and its concentration. In the present embodiment, the temperature of the washing water w2 to w6 and the concentration of the detergent of the washing water w2 to w5 are controlled in accordance with each washing mode A to E, and thus is particularly effective for such a dishwashing apparatus 1. As described above, one of the cleaning modes A to E set in advance as a plurality of different cleaning conditions is selected for each stain attached to the tableware by using different menus or ingredients. Therefore, anyone can easily perform the cleaning operation without making a mistake.
