Description

[Technical field]

[0001] The present invention relates to a washing method for washing tableware and a washing system applied in a washing facility for washing tableware. [Background technology]

[0002] Conventionally, when providing meals in various facilities (e.g., schools, medical facilities, and nursing homes), the tableware used at the facility has been collected and transported to a washing facility, where it is washed, and then disinfected and stored so that it can be used again (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-256965 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional tableware transport and washing system described above, the efficiency of the system is improved, for example, by storing used tableware in a special basket and transporting it to a washing facility in a container, where the tableware is placed in the basket while still stored in the basket and the basket and tableware are washed by the washing machine. In other words, the basket used to store and transport tableware has a special shape that can be used for both transport and washing, so that the tableware can be kept in the washing position not only during transport but also when washed by the washing machine. In addition, in order to operate the system, all baskets used in the system need to be dual-purpose tableware baskets having this special shape.

[0005] Such a multi-purpose dish basket is generally complicated in structure, and therefore more expensive than the transport baskets used in conventional general washing systems (i.e., systems in which tableware transported in a transport basket is removed from the transport basket, lined up one by one on a conveyor for washing, and the washed tableware is stored in the transport basket for the next use). Therefore, when replacing the above-mentioned general washing system with a new washing machine using a multi-purpose dish basket that washes tableware while it is stored in the basket due to a breakdown or deterioration over time, not only the washing machine but also the transport baskets must be replaced to accommodate the new washing machine. Furthermore, since the size and number of tableware that can be stored in the multi-purpose dish basket and the transport basket of the general washing system are different, it may be necessary to replace them with a disinfection storage cabinet or a mobile container that can accommodate the multi-purpose dish basket. For these reasons, in conventional systems, the cost of replacing the washing machine and the basket (and thus the operating cost of the washing equipment) is high.

[0006] One object of the present invention is to provide a tableware washing method and washing system that is advantageous in terms of operating costs of the washing equipment. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the cleaning method and cleaning system according to the present invention are characterized as follows. [1] A method for washing tableware used in a food service facility, comprising: A transporting process of storing the tableware in a transport basket and transporting the tableware to a washing facility; a pre-washing process of removing the tableware from the transport basket transported in the transporting process and transferring and storing the tableware in a washing basket that stores the tableware in a washing position; a first washing step of washing the tableware using a first washing machine which conveys the washing basket containing the tableware in the pre-washing step and sprays washing water to wash the tableware; a post-washing process of removing the tableware washed in the first washing process from the washing basket and transferring it to the transport basket for storage; and a re-transportation process of transporting the transport basket containing the tableware in the post-cleaning process to the food service facility. It is a cleaning method. [2] The cleaning method according to the above [1], The method further includes a second washing step of washing the transport basket by using a second washing machine which sprays washing water onto the transport basket while transporting the transport basket emptied of the tableware removed in the pre-washing step, In the post-cleaning step, The tableware washed in the first washing step is removed from the washing basket and transferred to the transport basket washed in the second washing step for storage. It is a cleaning method. [3] In the cleaning method according to the above item [1], The cleaning posture is: The tableware is in an open position facing forward in the conveying direction of the first washer, In the pre-cleaning step, The plurality of dishes in the washing position are stored in the washing basket in a stacked state in the conveying direction. It is a cleaning method. [4] The cleaning method according to the above [1], The washing basket is emptied after the tableware is removed in the post-washing step, and the washing basket is returned to the washing inlet of the first washing machine from the washing outlet of the first washing machine. It is a cleaning method. [5] In the cleaning method according to the above item [1], The number of dishes that can be stored in the washing basket is greater than the number of dishes that can be stored in the transport basket. It is a cleaning method. [6] A washing system for use in a washing facility for washing tableware, comprising: A transport basket for storing the tableware used in the food service facility and transporting it to the washing facility; A washing basket for storing and washing the tableware; a first washing machine that conveys the washing basket containing the tableware while spraying washing water to wash the tableware; Equipped with The tableware used at the food service facility is stored in the transport basket and carried to the washing facility; The tableware is removed from the transport basket brought into the washing facility, and transferred to the washing basket in a predetermined washing position and stored therein; Using the first washing machine, the tableware is washed; The dishwashing basket is configured to take out the dishwashed by the first dishwasher from the dishwashing basket, to transfer the dishwashing basket to the dishwashing basket, and to transport the dishwashing basket from the dishwashing facility. It is a cleaning system. [7] The cleaning system according to [6] above, Further provided is a second cleaning machine that cleans the transport basket while transporting it; The transport basket is emptied after the tableware used in the food service facility is removed, and is washed using the second washing machine; The tableware washed by the first washing machine is removed from the washing basket and transferred to and stored in the transport basket washed by the second washing machine. It is a cleaning system. [8] In the cleaning system according to the above [6], the washing position is a position in which the tableware is opened forward in a conveying direction of the first washing machine, The plurality of dishes in the washing position are stored in the washing basket in a stacked state in the conveying direction. It is a cleaning system. [9] In the cleaning system according to the above [6], The first cleaning machine is The washing unit washes the tableware, and the return unit moves the washing basket, which is emptied after the tableware washed in the washing unit is removed, from the washing outlet of the washing unit to the washing inlet. It is a cleaning system.

[10] In the cleaning system according to the above [9], The first cleaning machine is The cleaning unit and the return unit are arranged so as to overlap each other in the vertical direction in the installation posture of the first cleaning machine. It is a cleaning system.

[11] In the cleaning system according to the above [6], The number of dishes that can be stored in the washing basket is greater than the number of dishes that can be stored in the transport basket. It is a cleaning system. Effect of the Invention

[0008] According to the washing method of the configuration of [1] above and the washing system of the configuration of [6] above, the transport basket for transporting tableware and the washing basket for washing tableware are different. Then, the tableware used in the food service facility are stored in the transport basket and transported, and the tableware is transferred from the transport basket to the washing basket and stored, and then the tableware is washed by the first washing machine. After that, the washed tableware is transferred from the washing basket to the transport basket and stored, and the transport basket and the tableware are transported again. As a result, when the washing machine used in the above-mentioned conventional general washing system is replaced with a new first washing machine that can wash the tableware while it is stored in the washing basket, even if the washing basket for washing the tableware with the new first washing machine is required to be purchased or replaced, the transport basket can be continued to be used as it is, so that the replacement of the transport basket can be avoided. Furthermore, since the replacement of the transport basket can be avoided, there is no need to change the disinfection storage cabinet or container. Therefore, the washing method and washing system of this configuration are excellent in terms of operating costs of washing equipment.

[0009] However, in the conventional system described above, when tableware is stored in the transport basket at the food service facility, not all of the tableware is stored in a position suitable for washing in the first washer. In contrast, with the washing method and washing system configured as described above, when tableware used at the food service facility is transferred from the transport basket to the washing basket and stored, the tableware can be stored in the washing basket in a washing position suitable for washing. This increases the washing efficiency of the tableware in the first washer, and the tableware can be washed properly. Therefore, the washing method and washing system configured as described above are also excellent in terms of tableware hygiene.

[0010] According to the washing method of the above-mentioned [2] and the washing system of the above-mentioned [7], the transport basket is washed with the second washer, and the washed tableware is transferred from the washing basket to the washed transport basket for storage. Thus, the washed tableware can be transported again in a more hygienic manner.

[0011] According to the washing method configured as [3] above and the washing system configured as [8] above, a plurality of dishes are stored in the washing basket in a posture (washing posture) in which the dishes are open toward the front in the conveying direction by the first washer. As a result, for example, by spraying washing water onto the dishes from above, the washing water flows through the gaps between adjacent dishes and reaches the entirety of the dishes, so that even if a plurality of dishes are stacked, each of the dishes can be washed efficiently.

[0012] According to the washing method of the configuration [4] above and the washing system of the configuration [9] above, the washing basket that has been emptied after the washed dishes are removed is moved from the washing outlet to the washing inlet of the first washing machine. The washing basket moved in this way can be used again in the pre-washing process. This allows a large number of dishes to be washed without preparing an excessively large number of washing baskets. More specifically, the first washing machine has a washing section that washes the dishes and washing basket while transporting them, and a return section that moves the washing basket after washing from the washing outlet to the washing inlet of the washing section. This improves the workability of the washing operation compared to when an operator manually carries the washing basket from the washing outlet to the washing inlet. Here, the return section may be installed, for example, next to the washing section, or may be installed so as to be placed on top of the washing section. If the washing section and the return section are arranged so as to overlap each other in the vertical direction, as in the washing system of the configuration

[10] above, the installation space of the first washing machine can be reduced compared to when the washing section and the return section are installed next to each other.

[0013] According to the washing method as described in [5] above and the washing system as described in

[11] above, the number of dishes that can be stored in the washing basket is greater than the number of dishes that can be stored in the transport basket. This makes it possible to reduce the size of the basket and the weight of the dishes so that they are easy for workers at the food service facility to carry, while efficiently washing a large amount of dishes.

[0014] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading the following description of the embodiment of the present invention (hereinafter, referred to as "embodiment") with reference to the accompanying drawings. [Brief description of the drawings]

[0015] [Figure 1] FIG. 1 is a conceptual diagram showing the flow of work relating to the transportation and washing of tableware in a washing method and washing system according to an embodiment of the present invention. [Diagram 2]2(a) is a top view of the transport basket shown in FIG. 1, and FIG. 2(b) is a top view of the cleaning basket shown in FIG. [Diagram 3] FIG. 3 is a side view of the dishwasher shown in FIG. [Figure 4] FIG. 4 is a diagram for explaining how dishes and a washing basket are conveyed and washed together inside the dishwasher shown in FIG. [Diagram 5] FIG. 5 is a diagram for explaining how a transport basket is transported and washed inside the instrument washer shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] <Embodiment> Hereinafter, a washing method and a washing system 100 according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the washing system 100 is applied to a washing facility 1 for washing tableware 3, and tableware 3 used in a school or other food service facility 2 before washing (in other words, after use in the food service facility 2) is carried into the washing facility 1 to be washed and then carried out from the washing facility 1 to be used again in the food service facility 2. A washing method according to an embodiment of the present invention is applied to the washing system 100. Typical examples of the food service facility 2 include schools, medical facilities, and nursing care facilities. In this example, the washing system 100 is applied to the washing facility 1 as a facility separate from the food service facility 2. However, the washing system 100 may be applied to a washing room (washing facility 1) in the same facility, for example, by regarding a washing room and a dining room in the same facility as the washing facility 1 and the food service facility 2, respectively.

[0017] As shown in FIG. 1, used tableware 3 used in the food service facility 2 is stored in a transport basket 4 and placed in a container 5. Then, the tableware 3 stored in the transport basket 4 is carried into the washing facility 1. The used tableware 3 carried into the washing facility 1 is transferred from the transport basket 4 to a washing basket 7 for storage. At this time, as described later, a plurality of tableware 3 are stored in the washing basket 7 in a state where they are stacked in the front-to-rear direction so that each opens toward the front in the conveying direction of the dishwasher 10. Then, the tableware 3 and the washing basket 7 are washed together (i.e., collectively) by the dishwasher 10. The washing basket 7 has a shape suitable for washing by the dishwasher 10. The dishwasher 10 corresponds to the "first washing machine" in this invention.

[0018] Furthermore, the transport basket 4, which has become empty by transferring the tableware 3 to the washing basket 7, is washed by the utensil washer 20. The transport basket 4 has a shape suitable for transporting the tableware 3, and also suitable for washing by the utensil washer 20. The washed tableware 3 is transferred from the washed washing basket 7 to the washed transport basket 4 and stored, and is carried out from the washing facility 1 in the washed transport basket 4. More specifically, the washed tableware 3 is stored in the washed transport basket 4 in the disinfection storage cabinet 6, and the tableware 3 and the transport basket 4 are temporarily stored until the next use after being subjected to a process such as disinfection. Then, at the time of the next use, the container 5 containing the tableware 3 and the transport basket 4 is transported to the food service facility 2, and the tableware 3 is used again in the food service facility 2. The utensil washer 20 corresponds to the "second washer" in this invention.

[0019] In this way, the transport basket 4 is washed by the utensil washer 20 and is not washed by the dishwasher 10. Therefore, even if the dishwasher 10 is replaced and the shape or the like of the dishwasher 10 is changed, it is possible to avoid replacing the transport basket 4 and the disinfection storage cabinet 6 and container 5 that store the transport basket 4 containing the tableware 3.

[0020] For the sake of convenience, the terms "front", "rear", "left", "right", "upper" and "lower" are defined as shown in Figs. 2 to 5. The "front-rear direction", "left-right direction" and "up-down direction" are mutually perpendicular. The front-rear direction coincides with the conveying direction (direction of conveying path) of the tableware 3 and the washing basket 7 by the washing section 11 (see Fig. 3) of the dishwasher 10, which will be described later, the conveying direction (direction of conveying path) of the washing basket 7 by the return section 12 (see Fig. 3) of the dishwasher 10, which will be described later, and the conveying direction (direction of conveying path) of the transport basket 4 by the utensil washer 20, and the front side and the rear side correspond to the front and rear of the conveying path of the washing section 11 of the dishwasher 10 and the utensil washer 20, respectively, and also correspond to the rear and front of the conveying path of the return section 12 of the dishwasher 10, respectively. The transport basket 4, the washing basket 7, the dishwasher 10 and the utensil washer 20 will be described below in order.

[0021] First, the transport basket 4 will be described. The transport basket 4 is a basket for storing and transporting a plurality of tableware 3. In this example, as shown in Fig. 2(a) and Fig. 5, the transport basket 4 has a substantially rectangular box shape having a bottom wall and four side walls and opening upward. Each of the bottom wall and four side walls of the transport basket 4 has a structure in which a plurality of rod-shaped members are arranged vertically and horizontally in a lattice pattern to form a plurality of openings. In this example, as shown in Fig. 2(a), the transport basket 4 stores a plurality of tableware 3 stacked vertically so that each opens upward. In the example shown in Fig. 2(a), a stack of a plurality of tableware 3 stacked vertically is stored so as to be arranged in two rows in the front-rear direction and two rows in the left-right direction. However, the storage posture of the tableware 3 in the transport basket 4 is not particularly limited, and multiple pieces of tableware 3 may be stored in the transport basket 4 stacked with each piece opening downward, forward or backward, or multiple pieces of tableware 3 may be stored in the transport basket 4 with some of the tableware 3 stacked in a different direction from the other parts.

[0022] Next, the washing basket 7 will be described. The washing basket 7 is a basket for storing and washing a plurality of tableware 3. The washing basket 7 has a shape suitable for washing by the dishwasher 10 (more specifically, the washing unit 11), and in this example, as shown in FIG. 2(b) and FIG. 4, etc., has a substantially rectangular box shape having a bottom wall and four side walls and opening upward. Each of the bottom wall and four side walls of the washing basket 7 has a structure in which a plurality of rod-shaped members are arranged vertically and horizontally in a lattice pattern to form a plurality of openings. The washing basket 7 is designed so that the number of tableware 3 that can be stored in the washing basket 7 is greater than the number of tableware 3 that can be stored in the transport basket 4. As a result, a large amount of tableware 3 can be washed efficiently. As shown in FIG. 2(b), the washing basket 7 stores a plurality of tableware 3 stacked in the front-rear direction so that each opens toward the front. In the example shown in FIG. 2(b), a stack of a plurality of tableware 3 stacked in the front-rear direction is stored so as to be arranged in multiple rows in the left-right direction.

[0023] Next, the dishwasher 10 will be described. As shown in FIG. 3, the dishwasher 10 is composed of a washing section 11 and a return section 12. The return section 12 is arranged so as to overlap (place) on top of the washing section 11. This allows the installation space of the dishwasher 10 to be smaller than when the washing section 11 and the return section 12 are installed side by side. As described below, the washing section 11 performs the function of washing the washing basket 7 containing the tableware 3 while transporting it. The return section 12 performs the function of moving the washing basket 7, which has become empty by transferring the tableware 3 from the washing basket 7 to the transport basket 4 after washing by the washing section 11, from the washing outlet 13b to the washing inlet 13a of the washing section 11.

[0024] As shown in Fig. 3, the washing section 11 has a housing 13 having a generally rectangular cylindrical shape that is long in the front-rear direction. The rear end opening of the housing 13 functions as a washing inlet 13a through which the washing basket 7 containing the tableware 3 is inserted, and the front end opening of the housing 13 functions as a washing outlet 13b through which the tableware 3 and the washing basket 7 are discharged after washing. The internal space that is long in the front-rear direction of the housing 13 functions as a washing space R1 (see Fig. 4) in which the tableware 3 and the washing basket 7 are washed together as they are transported. A plurality of opening / closing doors 16 for maintenance are provided on a side wall that is long in the front-rear direction of the housing 13 so as to be spaced apart in the front-rear direction.

[0025] A conveying device 14 (see FIG. 4) for conveying tableware 3 and washing basket 7 is provided on the bottom wall (wall defining the lower end of washing space R1) long in the front-rear direction of the housing 13. Specifically, the conveying device 14 includes a conveying conveyor that is wound around a plurality of gears (not shown) arranged at intervals in the front-rear direction so as to extend in the front-rear direction. The conveying conveyor is driven to rotate in the direction indicated by the white arrow in FIG. 4 by an electric motor (not shown), so that the washing basket 7 containing the tableware 3 inserted from the washing inlet 13a and placed on the conveying conveyor moves forward (forward of the conveying path by the conveying device 14) toward the washing outlet 13b in the washing space R1. A plurality of spray nozzles 15 (see FIG. 1 and FIG. 4) for spraying washing water downward into the washing space R1 are provided at intervals in the front-rear direction on the ceiling wall (wall defining the upper end of washing space R1) long in the front-rear direction of the housing 13. For this reason, in the washing space R1, washing water is sprayed toward the tableware 3 and the washing basket 7 from above as they are moved forward by the transport device 14. Furthermore, a spray nozzle (not shown) is provided on the ceiling wall of the housing 13, forward of the multiple spray nozzles 15, for spraying rinsing water onto the tableware 3 and the washing basket 7 after they have been washed with the washing water.

[0026] As shown in FIG. 3, the return section 12 is arranged so as to overlap (place) on the housing 13 of the cleaning section 11, which is long in the front-rear direction. The return section 12 is provided with a transport device 17 that has a transport conveyor and extends in the front-rear direction, similar to the transport device 14 of the cleaning section 11. The transport conveyor of the transport device 17 is rotated by an electric motor (not shown) in the opposite direction to the transport conveyor of the transport device 14. As a result, by placing the emptied cleaning basket 7 after cleaning at a position located above the cleaning outlet 13b on the transport device 17 (transport conveyor), the cleaning basket 7 after cleaning moves backward (forward of the transport path by the transport device 17) from the cleaning outlet 13b toward the cleaning inlet 13a. Note that since the upper surface of the housing 13 is at a high position relative to the operator, the starting end and the terminal end of the return section 12 are each inclined downward. The transport conveyor of the transport device 17 does not extend to the terminal end, and another transport conveyor is provided at the terminal end. This allows the cleaning basket 7 to wait on the return section 12 until the worker takes the cleaning basket 7 from the return section 12. The terminal end of the return section 12 may be a placement table without a transport conveyor.

[0027] Next, the utensil washer 20 will be described. As shown in Figure 1, the utensil washer 20 has a housing 21 that is a generally rectangular cylinder that is long in the front-rear direction. The rear end opening of the housing 21 functions as a cleaning inlet 21a through which empty transport baskets 4 are inserted, and the front end opening of the housing 21 functions as a cleaning outlet 21b through which cleaned transport baskets 4 are discharged. The internal space of the housing 21 that is long in the front-rear direction functions as a cleaning space R2 (see Figure 5) in which the transport baskets 4 are cleaned as they are transported.

[0028] A conveying device 22 (see FIG. 5) for conveying the conveying basket 4 is provided on the bottom wall (wall defining the lower end of the cleaning space R2) long in the front-rear direction of the housing 21. Specifically, the conveying device 22 is configured to include a conveying conveyor that is wound around a plurality of gears (not shown) arranged at intervals in the front-rear direction so as to extend in the front-rear direction. This conveying conveyor is driven to rotate in the direction indicated by the white arrow in FIG. 5 by an electric motor (not shown), so that the conveying basket 4 that has been inserted from the cleaning inlet 21a and placed on the conveying conveyor moves forward (to the front of the conveying path by the conveying device 22) toward the cleaning outlet 21b in the cleaning space R2. A plurality of spray nozzles 23 (see FIG. 1 and FIG. 5) for spraying cleaning water downward into the cleaning space R2 are provided at intervals in the front-rear direction on the ceiling wall (wall defining the upper end of the cleaning space R2) long in the front-rear direction of the housing 21. For this reason, in the cleaning space R2, cleaning water is sprayed toward the transport basket 4 from above the transport basket 4 which is moved forward by the transport device 22. Furthermore, on the ceiling wall of the housing 21, a spray nozzle (not shown) is provided forward of the multiple spray nozzles 23 for spraying rinsing water onto the transport basket 4 after it has been cleaned with the cleaning water.

[0029] Next, a procedure (i.e., a washing method) for washing tableware 3 in the washing facility 1 will be described. First, tableware 3 used in a school or other school lunch facility 2 is placed in a transport basket 4 and then put into a container 5, and transported to the washing facility 1. This work process corresponds to the "transport process" in this invention.

[0030] Next, the used tableware 3 brought into the washing facility 1 is transferred from the transport basket 4 to the washing basket 7 for storage as described above. At this time, although multiple types of tableware 3 are stored in the transport basket 4, all the tableware 3 are temporarily removed from the transport basket 4 and, together with the tableware 3 in the other transport baskets 4, a specified number of tableware 3 are stacked for each type of tableware 3. Then, as shown in FIG. 2(b), multiple specified numbers of tableware are lined up and stored in the washing basket 7. This allows the worker to store the specified number of tableware 3, improving the workability of the work of transferring the washed tableware 3 to the transport basket 4. This work process corresponds to the "pre-washing process" in this invention.

[0031] Next, the washing basket 7 containing the used tableware 3 is put into the washing space R1 of the dishwasher 10 (washing section 11) through the washing inlet 13a. The put-in tableware 3 and washing basket 7 are moved forward in the washing space R1 toward the washing outlet 13b by the conveying device 14, and are washed with washing water sprayed from above by the multiple spray nozzles 15. Here, the washing basket 7 stores multiple tableware 3 in a washing position (i.e., stacks and stores the tableware 3 so that it opens toward the front (the front of the conveying path by the conveying device 14)) and washing water is sprayed toward the tableware 3 from above, so that the washing water flows through the gaps between adjacent tableware 3 and spreads over the entire tableware 3, so that even if a large number of tableware 3 are stacked, the entire tableware 3 can be washed efficiently. The tableware 3 and washing basket 7 washed in the washing space R1 of the dishwasher 10 are discharged to the outside of the dishwasher 10 (washing section 11) through the washing outlet 13b. This process corresponds to the "first cleaning process" in this invention.

[0032] Furthermore, the transport basket 4, which has been emptied by transferring the tableware 3 to the washing basket 7, is placed into the washing space R2 of the utensil washing machine 20 via the washing inlet 21a. The placed transport basket 4 is moved forward within the washing space R2 toward the washing outlet 21b by the conveying device 22, and is washed with washing water sprayed from above by the multiple spray nozzles 23. The transport basket 4 washed in the washing space R2 of the utensil washing machine 20 is discharged outside the utensil washing machine 20 via the washing outlet 21b. This work process corresponds to the "second washing process" in this invention.

[0033] Next, the washed tableware 3 discharged from the washing outlet 13b of the dishwasher 10 to the outside are transferred and stored from the washing basket 7 to the transport basket 4 discharged from the washing outlet 21b of the utensil washer 20 to the outside. At that time, the appropriate number of tableware 3 is counted and stored for each transport basket 4. This work process corresponds to the "post-washing process" in the present invention. In this example, after the tableware 3 and the transport basket 4 are subjected to a process such as disinfection, the tableware 3 and the transport basket 4 are temporarily stored in the disinfection storage cabinet 6 until the next use.

[0034] Furthermore, the washing basket 7, which has become empty by transferring the washed tableware 3 from the washing basket 7 to the transport basket 4, is placed at a location above the washing outlet 13b on the transport device 17 (transport conveyor) of the return section 12 of the dishwasher 10. As a result, the washing basket 7 after washing moves backward (to the front of the transport path by the transport device 17) from the washing outlet 13b toward the washing entrance 13a. This improves the workability of the washing operation compared to the case where an operator manually transports the washing basket 7 from the washing outlet 13b to the washing entrance 13a. The used tableware 3 that is subsequently brought into the washing facility 1 is transferred from the transport basket 4 to the washing basket 7 transported to the washing entrance 13a by the transport device 17 of the return section 12. This work process corresponds to the "return process" in this invention.

[0035] Next, when the tableware 3 is to be used next time, the transport basket 4 is taken out from the disinfection storage cabinet 6, and the transport basket 4 is stored in the container 5 and removed from the washing facility 1. In this way, the washed tableware 3 is transported stored in the post-wash transport basket 4, so that the washed tableware 3 can be hygienically reused. This work process corresponds to the "re-transport process" in this invention.

[0036] <Actions and Effects> According to the washing method and washing system 100 of this embodiment, the transport basket 4 for transporting the tableware 3 and the washing basket 7 for washing the tableware 3 are different. The tableware 3 used in the food service facility 2 is stored in the transport basket 4 and transported, and the tableware 3 is transferred from the transport basket 4 to the washing basket 7, and then the tableware 3 is washed by the dishwasher 10. After that, the washed tableware 3 is transferred from the washing basket 7 to the transport basket 4 and stored, and the transport basket 4 and the tableware 3 are transported again. As a result, when replacing the dishwasher used in the conventional general washing system with a new dishwasher 10 that can wash the tableware 3 while it is stored in the washing basket 7, even if the washing basket 7 for washing the tableware 3 with the new dishwasher 10 is required to be purchased or replaced, the transport basket 4 can be continued to be used as it is, and replacement of the transport basket 4 can be avoided. Furthermore, since replacement of the transport basket 4 can be avoided, there is no need to change the disinfection storage cabinet 6 or the container 5. Therefore, the cleaning method and cleaning system 100 according to this embodiment are advantageous in terms of operating costs of the cleaning equipment.

[0037] Furthermore, when the tableware 3 is stored in the transport basket 4 in the food service facility 2, not all of the tableware 3 is stored in a position suitable for washing in the dishwasher 10. In contrast, according to the washing method and washing system of this embodiment, when the tableware 3 used in the food service facility 2 is transferred from the transport basket 4 to the washing basket 7, the tableware 3 is stored in the washing basket 7 in a washing position suitable for washing. This improves the washing efficiency of the tableware 3 in the dishwasher 10, and the tableware 3 can be washed appropriately. Therefore, the washing method and washing system 100 of this embodiment is also excellent in terms of hygiene of the tableware 3.

[0038] Furthermore, according to the washing method and washing system 100 of this embodiment, the transport basket 4 is washed in a utensil washer, and the washed tableware 3 is transferred from the washing basket 7 to the washed transport basket 4 and stored therein. Therefore, the washed tableware 3 can be transported again in a more hygienic manner.

[0039] Furthermore, according to the washing method and washing system 100 of this embodiment, multiple dishes 3 are stored in the washing basket 7 in a posture (washing posture) in which the dishes 3 are open toward the front in the conveying direction by the dishwasher 10. As a result, for example, by spraying washing water toward the dishes 3 from above, the washing water flows through the gaps between adjacent dishes 3 and reaches the entire dishes 3, so that even if multiple dishes 3 are stacked, each of the dishes 3 can be washed efficiently in its entirety.

[0040] Furthermore, according to the washing method and washing system 100 of this embodiment, the washing basket 7 that has been emptied after the washed tableware 3 has been removed is reused in the pre-washing process. This allows a large number of tableware 3 to be washed without preparing an excessively large number of washing baskets 7. More specifically, the dishwasher 10 has a washing section that washes the tableware 3 and the washing basket 7 while transporting them, and a return section that moves the washing basket 7 after washing from the washing outlet to the washing inlet of the washing section. This improves the workability of the washing operation compared to when an operator manually carries the washing basket 7 from the washing outlet to the washing inlet. Here, the return section may be installed, for example, next to the washing section, or may be installed so as to be placed on top of the washing section. Furthermore, by arranging the washing section and the return section so as to overlap each other in the vertical direction, the installation space of the dishwasher 10 can be reduced compared to when the washing section and the return section are installed next to each other.

[0041] Furthermore, according to the washing method and washing system 100 of this embodiment, the number of tableware 3 that can be stored in the washing basket 7 is greater than the number of tableware 3 that can be stored in the transport basket 4. This allows the size of the basket and the weight of the tableware 3 to be kept small so that workers at the food service facility 2 can easily transport the tableware 3, while allowing a large amount of tableware 3 to be washed efficiently.

[0042] <Other forms> The present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiments, and appropriate modifications, improvements, etc. are possible. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

[0043] In the above embodiment, the washing system 100 includes the utensil washing machine 20 in addition to the dishwasher 10. In contrast, the washing system 100 does not necessarily need to include the utensil washing machine 20. In this case, for example, the transport basket 4 that has been emptied by transferring the tableware 3 to the washing basket 7 may be manually washed by an operator, and the washed tableware 3 may be transferred from the washing basket 7 to the washed transport basket 4 for storage.

[0044] Furthermore, in the above embodiment, dishwasher 10 includes return section 12 in addition to washing section 11. However, dishwasher 10 does not need to include return section 12. In this case, an operator manually carries empty washing basket 7 from washing outlet 13b to washing inlet 13a. Furthermore, in the above embodiment, dishwasher 10 includes washing section 11 and return section 12 arranged so as to be stacked vertically. However, dishwasher 10 may include washing section 11 and return section 12 arranged so as to be adjacent to each other.
