Description

  The present invention relates to a tableware storage tool and a tableware cleaning method in a situation where a relatively large amount of tableware, such as dishes, bowls, and trays, is used, particularly in school, hospital, etc. .

  Conventionally, with regard to a tableware cleaning device that is an object to be cleaned, the tableware and the storage device (tableware bowl) are separated and placed on a conveyor for cleaning, or the tableware is stored in the storage device and cleaned in the cleaning device. There is something to do. In recent years, in order to save labor, facilitate handling, and reduce the size of the cleaning device and tableware storage device, products that have been cleaned in the cleaning device while storing the tableware in the storage device have been developed. It has been known.

  As described in Japanese Patent Application Laid-Open No. H10-228561, there is a type in which tableware is stored by giving a certain interval between dishes, and washing water is supplied at a certain interval provided between the dishes to wash the tableware. In order to provide a fixed interval between the plurality of tableware, a plurality of bent metal bars for supporting the vicinity of the central portion of the tableware are provided in the longitudinal direction of the rectangular tableware storage basket.

  Moreover, as described in Patent Document 2, a tableware container capable of freely expanding and reducing the interval between adjacent tableware can be separated, and the interval between adjacent tableware can be separated during cleaning, while being conveyed. When it is desired to have a small volume, such as when storing or storing, there is a tableware container that can narrow the interval between adjacent tableware.

  In the said patent document 2, in order to expand and contract the space | interval of adjacent tableware freely, it is comprised as follows. A plurality of U-shaped frames that are juxtaposed to each other to form a tableware storage space for storing a plurality of tableware, and are connected to each side of the U-shaped frame so that adjacent U-shaped frames can be separated and approached. A pair of link members to be connected, a receiving frame extending between the pair of link members, and a pair of projections provided at the upper end of the U-shaped frame and projecting toward the tableware storage space, In a state in which the shape frame approaches, the pitch between the protrusions is set to be substantially the same as the pitch between the outer edges of the plurality of tableware to be stored, and the outer surface of the tableware stored in the tableware storage space is adjacent to the receptacle By engaging the edge of the plate, the protrusion engages with the outer edge of the tableware, and the edge of the tableware engages with the side of the main body of the receiving plate located in front of the tableware. When they are separated from each other, Accommodating space accommodating ware are spaced apart from each other, when the U-shaped frame to each other is brought close are those dishes contained in tableware housing space was made to approach each other.

  In addition, as described in Patent Document 3, a plurality of support bars arranged along the stacking direction of the tableware around the tableware storage unit, and each of these support bars to hold the peripheral edge of the tableware, respectively. A holding member having a locking portion that is mounted so as to be movable plurally is provided, the inner surfaces of a plurality of tableware corresponding to the number of holding members are directed upward, and a holding member is interposed between each tableware. When the tableware is stored in a stacked state in the tableware storage section, the tableware bowl is configured so that the tableware can move together with the holding member by a predetermined distance according to the shape and size of the tableware above the tableware at the top. is there.

  In Patent Document 3, a plurality of tableware are stored in a tableware storage section of the tableware table with a holding member interposed between the tableware, and the inner surface of the tableware is directed in the traveling direction. By moving through the cleaning device equipped with the cleaning water jet nozzle in a posture and sequentially applying cleaning water from the top tableware, the tableware is moved forward in the direction of movement of the tableware together with the holding member by the energy of the cleaning water. This is a tableware cleaning method in which cleaning is performed sequentially with cleaning water while moving and creating an interval necessary for cleaning between adjacent tableware. The thing described in the said patent document 3 has the characteristics which can make a tableware container small and lightweight also at the time of washing | cleaning other than the time of washing | cleaning compared with what was described in patent document 2. FIG.

Moreover, as described in Patent Document 4, the peripheral ends of a plurality of tableware in which the front side and the back side are overlapped in the horizontal direction are supported by the plurality of supports along the overlap direction, and located at the top. The position of the front side of the tableware and the back side of the tableware is regulated by a position regulating member so that movement and change of posture along the stacking direction of the plurality of tableware can be freely controlled within a predetermined range. The cleaning water is sequentially sprayed along the overlapping direction from the nozzles to the peripheral ends of the plurality of tableware stored in the storage tool, and the contacting adjacent tableware is separated by the cleaning water sprayed from the nozzles. The plurality of dishes are sequentially washed by the flow of washing water that has flowed into the separated intervals.

  However, what was described in the said patent document 1 is set so that the tableware which is a to-be-cleaned object may mutually be located at predetermined intervals. Therefore, the volume occupied by the container becomes larger than when the tableware is simply transported in a stacked state, and a longer space is required in the cleaning device to provide a fixed interval between the plurality of tableware. There is a limit to downsizing. Furthermore, a relatively large space is required in the process of transporting the container containing the tableware, and it is necessary to set the tableware one by one in the tableware bowl, which is problematic in terms of labor saving.

  Moreover, although what was described in the said patent document 2 can miniaturize a container except at the time of washing | cleaning, it is the several tableware which is a to-be-washed object similarly to what was described in patent document 1 at the time of washing | cleaning. Since a certain interval is provided between them, a longer space is required in the cleaning device, and there is a limit to downsizing the cleaning device. Further, it takes time and labor to expand and contract the tableware container, and the configuration becomes complicated, resulting in an increase in weight and cost.

  Furthermore, since it is necessary to support and restrain each of the plurality of tableware, the pair of protrusions provided on the upper end portion of the U-shaped frame of the tableware container are projected with the plurality of U-shaped frames approaching. It is necessary to set the pitch between the outer edges of the plurality of tablewares to be accommodated to be substantially the same. However, solids such as leftovers and pieces of meat tend to remain on the surface of the tableware after eating. If left outside the center, the stacked tableware will tilt. Therefore, the pitch between the outer edges of the plurality of tableware does not match the pitch between the projections, and there is a possibility that the tableware cannot be stored in the tableware container.

  Furthermore, especially in the case of tableware (porcelain tableware) produced by the baking method, there is a large variation in the height and radial outer edge size of each tableware, and the pitch and protrusions between the outer edges of the plurality of tableware due to the accumulated size variation of the plurality of tableware. There is a risk that it cannot be stored in the tableware container because the pitch does not match. Moreover, depending on the tableware used for eating, the table | surface where the pitch of the outer edges of tableware is small and close is included. In this case, it is difficult to form protrusions for holding each tableware, and the strength is remarkably lowered and easily damaged. Furthermore, the tableware stored in the tableware container must be limited or sorted, and is not versatile. Moreover, since the configuration of the tableware container is complicated, there is a problem that it is difficult for the washing water to hit the tableware sufficiently and it takes time to clean the tableware container itself together with the tableware.

  Moreover, since what was described in above-mentioned patent document 3 needs to support each of the several tableware which is a to-be-cleaned object, the several support rod arrange | positioned along the stacking direction of tableware, and tableware In order to hold the peripheral edge, a holding member having a locking portion movably mounted on each of these support rods is provided. However, like what was described in Patent Document 2, solids such as leftovers and pieces of meat are likely to remain on the surface of the tableware after eating, and when these tableware are stacked, the pitch between the outer edges of a plurality of tableware And the pitch of the holding members do not match and there is a possibility that they cannot be stored in the tableware container. In particular, in the case of tableware by the baking method, the height and radial outer edge size variation of each tableware is large, and due to the cumulative size variation of the plurality of tableware, the pitch between the outer edges of the plurality of tableware and the pitch between the holding members. There is a risk that it will not fit in the tableware.

  Moreover, depending on the tableware used for eating, the table | surface where the pitch of the outer edges of tableware is small and close is included. In this case, it is difficult to form a holding member for holding each tableware, and the strength is remarkably lowered and easily damaged. Furthermore, the tableware stored in the tableware container must be limited or sorted, and is not versatile. In addition, there is a possibility that the holding member having the locking portion cannot be freely moved with respect to the support bar due to the presence of foreign matter, etc., thereby causing the problem that the tableware cannot be separated and the cleaning performance is adversely affected. Furthermore, there is a problem that the configuration is complicated and the cost is increased.

Moreover, what was described in said patent document 4 was applied by this applicant in order to solve the subject of the tableware storage tool, the washing | cleaning method, and washing | cleaning apparatus which were described in the said patent documents 1 to 3. However, it is necessary to correspond to various tableware stored in the tableware storage tool.
In other words, tableware such as dishes, bowls, trays, etc., which are made of porcelain or metal and whose size is large, is increasing, and the mass is increased compared to resin. For this reason, especially in school lunches, when a child superimposes a predetermined number (for example, 20 to 40) of tableware and holds it as a unit in his / her hand, it becomes very heavy. This requires a lot of effort and there is a need for improvement in this handling. In addition, the posture of the tableware stored in the storage tool may become unstable.

  In addition, in the case where a plurality of dishes are washed by the flow of washing water that has flowed into spaced apart spaces, the adjacent dishes that are in contact with each other are separated from each other by the washing water sprayed from the nozzle. In the cleaning method, it is necessary to increase the spray pressure of the cleaning water for cleaning the tableware adjacent to each other, and it is necessary to devise in order to reduce the size of the cleaning device and save power.

  The present invention solves the above-described conventional problems, and aims to improve the storage of various tableware and stabilize the posture of the stored tableware. Moreover, it aims at removing the stain | pollution | contamination of the tableware accommodated in the storage tool reliably and efficiently.

  In order to solve the above-mentioned conventional problems, the tableware storage tool of the present invention includes a plurality of support bodies that support the peripheral ends of a plurality of tableware in which the front side and the back side are overlapped in the horizontal direction, along the overlapping direction, A position regulating member for partitioning the plurality of tableware into a plurality in the stacking direction, and a position on the front surface side of the tableware positioned at the top and the back side of the tableware positioned at the end for each of the plurality of partitioned tableware A position restricting member is provided, and the plurality of partitioned tableware are accommodated so that movement and posture change along the overlapping direction can be freely performed within a predetermined range.

  Further, in the tableware cleaning method of the present invention, the cleaning water is sequentially sprayed along the overlapping direction from the nozzles to the peripheral ends of the plurality of tableware stored in the storage tool, and the cleaning water sprayed from the nozzles makes contact therewith. The tableware adjacent to each other is separated and separated, and the plurality of dishes are sequentially washed by the flow of washing water that flows into the separated intervals.

  According to the tableware storage device of the present invention, it is possible to improve the storage of various tableware and to stabilize the posture of the stored tableware. In addition, according to the tableware cleaning method of the present invention, it is possible to reliably and efficiently remove tableware stains.

The peripheral end portions 37c of the plurality of dishes 37 are supported so as to freely slide along the overlapping direction by sliding freely on the support bodies 22, 23, 33, and 34.

Furthermore, a predetermined number of pieces of tableware stacked in the vertical direction (longitudinal direction) as one unit are positioned at the head of the plates 37 stored on the base plates 16 and 27 (position restricting members) of the storage device 14. The lower part on the front surface 37a side of the plate 37 is in contact with the position regulating member 38 for partitioning, and the part on the back surface 37b side of the plate 37 located at the tail is in contact with the base plates 16 and 27 (position regulating member). The position of is regulated.

In this state, this corresponds to a predetermined space (L2) between the front surface 37a of the plate 37 and the lower surface of the partitioning position regulating member 38 when the plurality of plates 37 are stored with the storage device 14 in the vertical direction. In a predetermined range, peripheral end portions 37c of the plurality of dishes 37 are supported so as to freely slide along the overlapping direction by freely sliding on the support bodies 22, 23, 33, and 34.

  As described above, the peripheral end portions 37c of the plurality of dishes 37 partitioned and stored by the partition position regulating member 38 can freely slide along the overlapping direction by sliding freely on the support bodies 22, 23, 33, and 34. While supporting, only the peripheral edge part 37c of the several plate | plate 37 whole, the surface 37a side of the plate | plate 37 located in the head, and the back surface 37b side of the plate | plate 37 located in the tail end are position-regulated. Thus, for each of the plurality of partitioned plates 37, a plurality of plates 37 in which the front surface 37a side and the back surface 37b side are horizontally stacked in a predetermined range corresponding to a predetermined space (L2) are moved along the stacking direction. In addition, the posture change in the vertical direction (longitudinal direction) and the horizontal direction (lateral direction) can be accommodated within a predetermined range.

  When the storage tool 14 is set in the horizontal direction, the center of gravity of the plate 37 is positioned on the back surface 37b side of the plate 37, whereby the plurality of plates 37 have the back end 37b side of the plate 37 facing down and the peripheral end portion 37c is the support 22. , 23, 33, 34, the plurality of dishes 37 are in contact with each other, and are inclined in the same direction and inclined at a predetermined angle (θ3) so as to overlap. Moreover, the space | interval (S2) of the lower side peripheral edge part 37c of the mutually adjacent dishes 37 will be in the state wider than the space | interval (S3) of the upper side peripheral edge part 37c.

  Next, the partition position regulating member 38 shown in FIG. 8 will be described. The partition position regulating member 38 is made of a material having elasticity, such as silicon rubber, for example, and the insertion port 38a is inserted from the circumferential direction of the support bodies 22, 23, 33, 34 and is held by the shaft hole 38b portion. Install. Since the partitioning position regulating member 38 has elasticity, it can be detachably attached to the supports 22, 23, 33, and 34, and also moved in the axial direction of the supports 22, 23, 33, and 34. It is configured to be able to. The material, configuration, and fixing method of the partition position regulating member 38 are not limited to this, and other means may be used.

As described above, the tableware storage device of the present invention includes a plurality of supports that support the peripheral ends of a plurality of tableware in which the front surface side and the back surface side are horizontally stacked, and the plurality of tableware. And a position regulating member for regulating the position of the front surface side of the tableware located at the top and the back side of the tableware located at the end for each of the plurality of partitioned tableware. Have
The partitioned plurality of tableware is stored so that movement and posture change along the stacking direction can be freely performed within a predetermined range (L2).

  In this way, a plurality of tableware is divided and stored in the storage device 14 partitioned into a plurality of sections by the partition position regulating member 38, and even if it is a heavy tableware, a large tableware, etc., the optimum number is one unit. This is set to be stored in the storage tool 14 or taken out. Thereby, the labor of storing or taking out the tableware in the storage tool 14 can be reduced. Therefore, the storage property of various tableware can be improved.

  Furthermore, it has a position regulating member that regulates the position of the front surface side of the tableware located at the head and the back surface side of the tableware located at the rearmost position, and the movement and posture change along the stacking direction of the plurality of partitioned tableware are predetermined. By storing the table so as to be free within the range, the posture of the stored tableware can be stabilized. Moreover, the washing with the washing water can be performed stably.

  Next, using FIG. 9 and FIG. 10, the tableware position adjusting members 100 a and 100 b are attached to the supports 22, 23, 33, and 34, and the plate located on the front side and the rearmost plate 37. An example will be described in which a plurality of dishes 37 are accommodated so that the distance between the positions that regulate the back side of 37 can be adjusted. The tableware position adjusting members 100a and 100b are the same as the partition position regulating member 38 described above.

In particular, in school lunches, the number of dishes 37 stored may vary depending on slight variations in the number of students in a class. When the number of students decreases, the number of dishes 37 stored in the storage device 14 also decreases, and the predetermined space (L2) increases. As a result, the inclination angle of the plurality of dishes 37 increases when the storage tool 14 is set in the horizontal direction, and the postures of the plurality of dishes 37 in the storage tool 14 vary and become unstable, and are adjacent to each other during cleaning, which will be described later. In some cases, the dish 37 cannot be reliably separated by the washing water.

  For this reason, as shown in FIG. 9 and FIG. 10 as an example, the predetermined space (L2) is adjusted to the optimum dimension by using the tableware position adjusting members 100a and 100b when the number of storages decreases. The tableware position adjusting members 100a and 100b are mounted on the support bodies 22, 23, 33, and 34 at positions corresponding to the interval (pitch) of the decrease in the peripheral end portion 37c of the plate 37, and the plate 37 shown in FIG. The predetermined space (L2) is adjusted to be the same as the case where it is stored as a number. In this case, the tableware position adjusting members 100a and 100b have a function of a position regulating member on the surface side 37a of the plate 37 at the head.

In the embodiment, the tableware position adjusting members 100a and 100b can be detachably attached to the support bodies 22, 23, 33, and 34 using the same member as the partitioning position regulating member 38, and are supported. The body 22, 23, 33, 34 can be moved in the axial direction. The tableware position adjusting members 100a and 100b are not limited in material, configuration, and fixing method, and may be other means.

For each of the plurality of partitioned dishes, tableware position adjusting members 100a and 100b are provided in the stacking direction of the plurality of dishes 37, and the front side of the dish 37 positioned at the top and the back side of the dish 37 positioned at the tail are regulated. Since the distance between the positions can be adjusted, it is possible to flexibly cope with the change in the number of the dishes 37 stored without changing the entire storage tool 14.

  Moreover, by providing the tableware position adjusting members 100a and 100b on the supports 22, 23, 33, and 34, the tableware position adjusting members 100a and 100b can be easily mounted according to necessity. Furthermore, since the tableware position adjusting members 100a and 100b can be moved in the stacking direction of the plurality of dishes 37, it is possible to easily cope with more fluctuations in the number of stored dishes 37. In addition, since the tableware position adjusting members 100a and 100b are detachable, it is possible to easily cope with the necessity.

  It is also possible to adjust the number of the plurality of partitioned dishes by changing the position of the partitioning position regulating member 38 in the stacking direction of the dishes. In this case, tableware with different materials, shapes, etc. can be stored in the same storage device 14 according to the respective conditions.

  Further, the partition position regulating member 38 can be easily mounted according to necessity by providing the support bodies 22, 23, 33, 34 in the same manner as the tableware position adjusting members 100a, 100b. Furthermore, by making the partitioning position regulating member 38 movable in the stacking direction of the plurality of dishes 37, it is possible to easily cope with more fluctuations in the number of stored dishes 37. Further, since the partitioning position regulating member 38 is detachable, it can be easily dealt with according to necessity.

  Next, FIGS. 11 to 13 are diagrams illustrating changes in the posture state of the dish during cleaning when a partition position regulating member and a tableware position adjusting member are provided and a plurality of dishes are stored in the storage tool. Moreover, in the figure, W shows the flow of the jetted washing water.

  11 (a), 11 (b), 12 (a), and 12 (b), the storage tool 14 is moved by the conveyor 2 with respect to the nozzles 10 and 11 that are fixedly arranged, so that the position restricting member 38 for partitioning is used. The state of washing the plurality of dishes 37 partitioned on the front side is shown.

  FIG. 11A shows a cleaning state of the surface 37a of the dish 37 located at the head in the moving direction of the storage tool 14. FIG. Washing water is sprayed from the nozzles 10 and 11 to the space between the surface 37a of the dish 37 and the frames 17 and 28 located at the head. As a result, the washing water from the nozzles 10 and 11 becomes a collision flow on the surface 37a of the dish 37 and diffuses to remove dirt. In particular, the cleaning water splashes between the surface 37a portion of the dish 37 and the frames 17 and 28 and strikes the surface 37a portion to reliably remove the dirt.

  In the state of FIG. 11A, the plurality of dishes 37 are inclined at a predetermined angle, but the washing water from the nozzles 10 and 11 gives dynamic pressure to the surface 37 a of the dish 37, As the washing water flows from above to below the space between the surface 37a and the frames 17, 28, the lower portion of the surface 37a of the dish 37 is separated from the tableware position adjusting member 100a as shown in FIG. The plurality of dishes 37 that are spaced apart and located from the head to the tail change from a posture inclined at a predetermined angle to a substantially vertical posture. Further, the washing water flows from the upper side to the lower side of the space between the surface 37a portion of the plate 37 and the frames 17 and 28, thereby removing dirt on the surface 37a of the plate 37.

  FIG. 12A shows a peripheral end portion 37c of a dish 37 in which the storage tool 14 is moved by the conveyor 2 with respect to the nozzles 10 and 11 fixedly arranged from the state of FIG. After hitting, the wash water enters the space (S3) between the peripheral end portion 37c of the dish 37 located at the head and the peripheral end portion 37c of the second dish 37 adjacent thereto, and the dynamic pressure and static pressure of the entered wash water The pressure acts on the back surface 37b of the top plate 37 and the front surface 37a of the second plate 37 to spread them, and the top plate 37 moves the support bodies 22, 23, 33 and 34, the peripheral end portion 37c slides and moves to contact the tableware position adjusting member 100a, and at the same time, the plate 37 located at the head and the adjacent second plate 37 are separated from the contacted state. The width in the moving direction of the storage device 14 for the cleaning water sprayed from the nozzles 10 and 11 does not need to be narrowed, and may be, for example, about the pitch dimension of the peripheral end portions 37 of the plates 37 adjacent to each other.

  Wash water flows from the upper part to the lower direction and from the upper part to the lateral direction in the spaced intervals, and the dirt on the back surface 37b of the dish 37 located at the head and the surface 37a of the second dish 37 is removed and washed. is there. When the washing water flows in the spaced intervals, the dirt on the front surface 37a and the back surface 37b of the dish 37 can be reliably removed and the formation of the spaced intervals can be maintained. In addition, the plurality of dishes 37 stored in the storage tool 14 is maintained in a substantially vertical posture.

Furthermore, after the container 14 moves, the cleaning water hits the peripheral end portion 37c of the second dish 37 and then the peripheral end of the third dish 37 adjacent to the peripheral end portion 37c of the second dish 37. The washing water enters the space (S3) with the portion 37c, and the dynamic pressure and static pressure of the entering washing water act on the back surface 37b of the second dish 37 and the surface 37a of the third dish 37 to push them. The second plate 37 is spread and contacts the first plate 37 as the peripheral end 37c is moved by sliding the support members 22, 23, 33, 34 toward the frames 17, 28. And the third plate 37 adjacent to the plate 37 are spaced apart from each other (not shown). When the washing water flows in the spaced intervals, the dirt on the front surface 37a and the back surface 37b of the dish 37 can be reliably removed and the formation of the spaced intervals can be maintained. This operation is sequentially repeated as the storage tool 14 moves.

  FIG. 12B shows a cleaning state when the cleaning water from the nozzles 10 and 11 is moved to the position of the back surface 37b of the dish 37 located at the tail by the movement of the storage tool 14. The washing water of the nozzles 10 and 11 flows in contact with the back surface 37b of the dish 37 located at the tail, and the dirt on the back surface 37b of the dish 37 located at the tail is removed and washed.

  In general, the back surface of the tableware is less dirty than the surface of the tableware, but the above operation reliably removes the stain on the back surface 37b of the plate 37 located at the tail.

  13 (a) and 13 (b) show that a plurality of dishes 37 partitioned by the conveyor 2 with respect to the nozzles 10 and 11 that are fixedly arranged are partitioned rearward of the partitioning position regulating member 38. Shows the state of washing.

  In FIG. 13A, as in the state of FIG. 11A, cleaning water is sprayed from the nozzles 10 and 11 onto the surface 37a of the dish 37 located at the head. As a result, the washing water from the nozzles 10 and 11 becomes a collision flow on the surface 37a of the dish 37 and diffuses to remove dirt.

  Thereafter, the cleaning operation similar to that shown in FIGS. 11A, 11B, 12A, and 12B is performed behind the partition position regulating member 38 by the movement of the storage tool 14 by the conveyor 2. Repeatedly in the plurality of dishes 37 divided on the side, the whole of the plurality of dishes 37 stored in the storage tool 14 is thereby washed. In the cleaning operation shown in FIGS. 11 to 13, the container 14 itself is also cleaned by the flow of the cleaning water sprayed from the nozzles 10 and 11 and the cleaning water from the dish 37.

  As described above, the cleaning operation shown in FIGS. 11 to 13 is performed in the rough cleaning zone 7a, the intermediate cleaning zone 7b, and the final cleaning zone 7c, and the cleaning of the dish 37 stored together with the storage tool 14 is completed. The dish 37 that has been cleaned is stored in the storage tool 14 by being dried, sterilized, or the like in the next step. In one cleaning zone, the cleaning operation shown in FIGS. 11 to 13 may be performed a plurality of times by movement in one direction of the storage device 14 and is selected as necessary.

In addition, although a bowl is a round-shaped tableware, and there are a square-shaped dish and a tray, the tableware storage device and the washing | cleaning method become the structure, washing | cleaning operation | movement, an effect | action, and an effect similar to the said dish 37.

Although not shown, the container 14 is moved back and forth by a driving means from one direction to clean the dish 37, or the container 14 is fixed and the nozzles 10 and 11 are moved back and forth by the driving means. By washing the dish 37, it is possible to reduce the size of the washing apparatus and save space. This is particularly suitable when the number of dishes 37 to be cleaned is relatively small.

As described above, in the tableware cleaning method of the present invention, the cleaning water is overlapped in the stacking direction from the nozzle to the peripheral edge of the tableware for each of the plurality of tableware partitioned by the partitioning position regulating member and stored in the storage tool. A plurality of dishes are sequentially washed by the flow of washing water that has flowed into the spaced intervals. This is a cleaning method for tableware.

Conventionally, in heavy tableware made of porcelain, metal, etc., or large tableware, a plurality of items stored in an inclined posture are used when the adjacent tableware that are in contact with each other are separated by washing water sprayed from a nozzle. It was difficult to change the tableware to a substantially vertical posture, and it was necessary to increase the washing water injection pressure.

In the cleaning method of the present invention, the cleaning water is sequentially sprayed from the nozzles for each of the plurality of tableware stored by dividing the heavy tableware and large tableware by the partitioning position regulating member into the storage tools. Therefore, it is easy to change a plurality of tableware stored in an inclined posture into a substantially vertical posture without increasing the spraying pressure of the washing water, and the adjacent tableware that are in contact with each other are reliably separated and separated. Cleaning can be carried out by the flow of the cleaning water flowing into the. Therefore, according to the washing | cleaning method of the tableware of this invention, the stain | pollution | contamination of tableware can be removed reliably and efficiently.

  The present invention is not limited to tableware, and can also be applied to cleaning objects to be cleaned such as machined parts.
