However, as described above, the dishes are rotated in sequence by the water pressure of the washing water, but depending on how the washing water hits the dishes, the dishes may move unexpectedly and the dishes may be lifted. It was.

The present invention has been made in view of such a point, and an object of the present invention is to wash dishes in a tableware basket while transporting the dishes in a stacking direction with the opening surface facing horizontally. It is an object of the present invention to provide a tableware basket capable of preferably forming a gap for washing between the front and rear tableware by preventing the tableware at the head in the transport direction from rising when spraying.

In view of the above problems, as a result of diligent studies by the inventors, by suppressing the lifting of the tableware at the head, the lifting of the tableware stacked in the standing posture after that is also suppressed, and the tableware can be placed in any position. It was discovered that the cleaning operation can be continued smoothly without sneaking in. Therefore, if a member that prevents such lifting is provided at the minimum necessary location, a simpler configuration can be realized. Therefore, the tableware and the tableware basket for accommodating the tableware are mechanically provided. It was thought that such interference could be reduced.

The present invention has been made in view of such a point, and the tableware basket according to the present invention accommodates a plurality of tableware stacked in the same direction, and the opening surfaces of the plurality of stacked tableware are formed on the tableware. A tableware basket for sequentially washing the plurality of tableware with washing water from the first tableware while transporting the plurality of tableware in a state of being oriented in the horizontal direction, which is the transport direction of the tableware. Is formed with a storage space for accommodating the plurality of tableware stacked in the same direction, and the tableware basket is in the storage space with the opening surfaces of the plurality of tableware facing in the horizontal direction. A support member that supports a plurality of tableware from below and a regulation member that regulates the upward movement of the tableware in the storage space are provided, and the storage space has the opening surface of the plurality of tableware horizontal. In a state where the plurality of tableware is housed in the direction, the opening surface of the tableware is inclined with respect to the vertical direction due to the weight of the tableware, and under each tableware in contact with the support member. A size that allows the plurality of tableware to freely take a second posture in which each tableware stands up by rotating from the first tableware in order from the first tableware with the side edge as a fulcrum. The restricting member is arranged at a position where the upward movement of only the tableware on the front side is restricted in the state of taking the second posture.

According to the present invention, when washing a plurality of tableware contained in a tableware basket, the plurality of tableware is conveyed in the stacking direction with the opening surfaces of the plurality of stacked tableware facing horizontally in the tableware basket. While doing so, spray wash water from the top of the tableware basket onto the dishes in the tableware basket. Before the washing water is sprayed, the plurality of dishes housed in the tableware basket take a first posture in which the opening surface of the dishes is inclined with respect to the vertical direction due to the weight of the dishes.

Then, when the washing water is sequentially sprayed on a plurality of dishes as the tableware basket is transported, the second posture in a state of standing up from the first posture in order from the first tableware in the tableware transport direction due to the water pressure of the washing water. A gap is formed between the rotated tableware and the next tableware, and the washing water flows into this gap.

Here, according to the present invention, by providing the regulating member, the leading tableware is in the state of taking the first to the second posture, and the regulating member above the leading tableware causes the leading tableware to be on the leading side. The upward movement of only tableware is restricted. As a result, the regulation member with a simpler structure keeps the first tableware in the upright second posture without lifting during cleaning, which causes the inconvenience that the next tableware slips under the first tableware. It does not occur. As a result, the dishes are sequentially rotated from the first posture to the second posture by the washing water from the first tableware to the last tableware stacked, and a gap is sequentially formed between them. It is possible to pour washing water into the gap and wash the dishes in sequence. The term "only the first tableware" as used in the present invention means only the first tableware or only two or three dishes including the first tableware.

In a more preferred embodiment, the restricting member has a pair of extending portions extending from the front side in the transport direction to both sides above the leading tableware, and the pair of extending portions is said to be said. The leading tableware is formed so as to restrict the upward movement of only the leading tableware in the state of taking the second posture.

According to this aspect, at the time of washing, the leading tableware takes the first to second postures, and the support member below the leading tableware and the pair of rolls above the leading tableware. With the existing part, it is possible to stably suppress the upward movement of only the tableware on the front side.

Further, in a preferred embodiment in which the regulating member is provided with a pair of extending portions, the pair of extending portions extend from the front side in the transport direction toward both upper sides of the leading tableware. The distance between the tips of the extending portions toward the leading tableware is wider than the width of the leading tableware.

According to this aspect, the extending portion extends toward both sides above the leading tableware, and the distance between the tips of the extending portions toward the leading tableware is wider than the width of the leading tableware. Therefore, when the stacked tableware is stored in the tableware basket, it is possible to prevent the leading tableware from coming into contact with the extending portion.

In a more preferred embodiment, the tableware basket is further provided with an adjusting mechanism that adjusts the size of the storage space along the direction in which the tableware overlaps according to the number of a plurality of tableware to be stored.

According to this aspect, the accommodation space can be adjusted to the optimum size by the adjusting mechanism according to the number of dishes to be washed. Therefore, even if the number of dishes is different, the regulating member can be used. It is possible to prevent the top tableware from rising.

According to the present invention, when washing water is sprayed on the tableware in the tableware basket while transporting the tableware in the stacking direction with the opening surface facing the horizontal direction as the transport direction, the tableware at the head of the transport direction It is possible to prevent lifting. As a result, by spraying the washing water, a gap for washing is suitably formed between the front and rear dishes, and the dishes can be washed more effectively.

The tableware basket according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 13.

1. 1. About the dishwashing apparatus FIG. 1 is a schematic side view of the dishwashing apparatus 1 used for the tableware basket 3 according to the embodiment of the present invention. The dishwasher 1 is a commercial tableware that continuously cleans a plurality of dishes of the same type using the washing water W which is the jet water without immersing the tableware basket 3 in the immersion water while being housed in the tableware basket 3. It is a washing machine.

The dishwashing device 1 includes, for example, three washing units 10 along the transport direction d in which the tableware basket 3 is transported. In FIG. 1, the same reference numerals are given to the symbols of each cleaning unit 10 and the members constituting the cleaning unit 10, but each cleaning unit 10 controls the temperature of the cleaning water, adds detergent, etc., according to the cleaning purpose. Has been done. For example, each cleaning unit 10 may be composed of a rough cleaning unit, a detergent cleaning unit, and a finish cleaning unit in order from the upstream side in the tableware transport direction d. Further, the dishwashing apparatus 1 of the present embodiment is composed of three washing parts 10, but the number of washing parts and the like can be determined depending on the purpose of the washing, and the number thereof is particularly limited. is not it.

In each cleaning unit 10, an upper nozzle 11 and a lower nozzle 12 for spraying the cleaning water W onto the tableware housed in the tableware basket 3 conveyed to the conveyor 2 are arranged. The upper nozzle 11 and the lower nozzle 12 are arranged so that the spraying direction of the washing water W is inclined to the upstream side of the tableware transport direction d. In the dishwashing described later, if the tableware can be effectively washed only with the washing water W of the upper nozzle 11, the lower nozzle 12 may be omitted.

Each cleaning unit 10 is provided with a storage tank 16 that collects the cleaning water W discharged from the cleaning water W of the upper nozzle 11 and the lower nozzle 12 and houses the cleaning water W. In the storage tank 16, a pump 17 that pumps the stored washing water W to the upper nozzle 11 and the lower nozzle 12 is arranged. With this configuration, the cleaning water W of each cleaning unit 10 can be circulated and used in each cleaning unit 10.

The dishwashing device 1 is provided with a conveyor 2 that conveys the dishes stored in the tableware basket 3 from the inlet 15 of the dishwashing device 1 through each washing unit 10 to the outlet 18 of the dishwashing device 1. The conveyor 2 includes a chain belt 21 that moves from the inlet 15 to the outlet 18 of the dishwashing device while placing the tableware basket 3 housed in the dishes, a driven roller 23 around which the chain belt 21 is wound, and a drive roller 24. It has. The drive roller 24 is connected to the drive motor 25 via a drive belt 26.

With this configuration, when the drive motor 25 is driven, the drive roller 24 rotates via the drive belt 26, and the chain belt 21 wound around the drive roller 24 rotates the driven roller 23 while rotating each cleaning unit. Move within 10. As a result, the tableware basket 3 placed on the chain belt 21 can be transported from the inlet 15 to the outlet 18 of the dishwashing device 1.

2. 2. About the tableware basket 3 The tableware basket 3 will be described below. The tableware basket 3 shown in FIG. 2 is a posture for accommodating tableware, and the tableware basket 3 is, for example, a box-shaped structure formed by combining a plurality of linear members made of metal (for example, a wire having a circular cross section). It is a wire net basket, and its outer shell is approximately rectangular parallelepiped.

The tableware basket 3 has a frame body 32 formed by a rod-shaped frame material 32a arranged along the sides of the rectangular parallelepiped space so as to form a storage space 31 inside. The frame body 32 is integrated by bending a metal wire rod to be the frame material 32a or welding the wire rods to each other. Further, connecting rods 33, 33A, 33B, and 33C are connected to the portions of the frame members 32a facing each other of the frame body 32, which is each side portion of the tableware basket 3. As a result, the rigidity of the frame body 32 can be increased.

More specifically, the frame body 32 is formed by passing the frame material 32a to the sides other than one of the twelve sides of the rectangular parallelepiped that is the outer shell thereof. The position where the frame material 32a is not passed over the frame body 32 is the position of the upper side when the tableware basket 3 takes the posture of accommodating the tableware P in the accommodating space 31.

At this position, the tableware P can be introduced into the storage space 31 from above, and an opening 31a for taking in and out the tableware for taking out the stored tableware P from the storage space 31 can be formed (see FIGS. 2 and 3). ).

The opening 31a is a connecting rod located at an upper portion so that the tableware P can be accommodated from above when the tableware basket 3 takes a posture of accommodating the tableware P in the accommodating space 31, as shown in FIGS. 2 and 3. It is formed by bending a part of the fall prevention portion 41 of 33A and the regulation member 4 described later. The connecting rod 33A is connected to the pair of supporting members 36, 36 and the pair of guide members 51, 51, which will be described later, to the supporting connecting rod 33C via the connecting rod 33B.

In the tableware basket 3, three bottom support rods 34 that support the bottom surface of the tableware P when the tableware basket 3 takes a posture of accommodating the tableware P in the storage space 31 are provided in the frame body 32 and the connecting rod 33. It is connected to 33C. The bottom support rod 34 can support the load of the stacked tableware P in a state where the tableware P shown in FIG. 2 is housed in the tableware basket 3, and the tableware basket 3 shown in FIG. 6 cleans the tableware P. Even in the posture, it is possible to support the bottom of the tail end of the stacked and inclined tableware P.

A pair of support members 36, 36 are attached to the frame body 32 of the tableware basket 3. As shown in FIGS. 5 and 6, the pair of support members 36, 36 have the edges of the plurality of tableware P downward in the accommodation space 31 with the opening surfaces f of the plurality of tableware P oriented in the horizontal direction. It is supported by the connecting rods 33C and 33C.

In the present embodiment, the support member 36 has a round bar shape, and its surface is coated with resin. Further, as shown in FIG. 4, the support members 36, 36 are arranged so that the distance between them is narrower than the width B1 of the tableware P.

By providing the pair of support members 36, 36, even if the tableware basket 3 is rotated by 90 ° from the posture of accommodating the tableware P in the storage space 31 to the posture of washing the tableware P, the tableware P is the tableware basket 3. Never get out of. Further, since the support member 36 is coated with resin, the tableware P can easily slide on them. Therefore, as shown in FIGS. 7A and 7B, in the state where the plurality of tableware P is accommodated, the opening surface f of the tableware P becomes vertical in the vertical direction due to the weight of the tableware P before and after washing. It is possible to take a first tilted posture.

Here, the size of the accommodation space 31 can be adjusted by the adjustment mechanism 5 described later, and the size of the stacked tableware P can be adjusted to the above-mentioned first posture and the second posture. It has become.

The first posture is that when the tableware basket 3 takes the posture of washing the tableware P, the opening surface f of the tableware P is vertical due to the weight of the tableware P, as shown in FIGS. 7A and 7B. The posture is tilted with respect to the direction. The second posture is, as shown in FIGS. 7C and 7D, each tableware P that comes into contact with the pair of support members 36, 36 when the tableware basket 3 takes the posture of washing the tableware P. Each tableware P stands upright by rotating from the first tableware in order from the first tableware P1 with the lower edge as a fulcrum. 7 (c) and 7 (d) show a state in which the first three tableware Ps are in the second posture.

In the present embodiment, the edges of the tableware P are supported by arranging a pair of support members 36, 36 side by side, but the support members do not allow the tableware P to come out of the accommodation space 31 and are stacked. As long as the tableware P can be supported, the shape and number of the support members are not particularly limited.

As shown in FIG. 2, a pair of removal prevention frames 37, 37 for preventing the tableware P from coming out of the accommodation space 31 are further attached to the frame body 32 of the tableware basket 3. Specifically, the pair of pull-out prevention frames 37, 37 are attached along the opposite frame material 32a at a position opposite to the position where the support members 36, 36 are arranged. The space between the pair of pull-out prevention frames 37, 37 is narrower than the width B1 of the tableware P, like the support members 36, 36, and is further combined with the bending portion of the connecting rod 33A and the fall prevention portion 41. An opening 31a is formed so that the tableware P stacked in the vertical direction can pass through the accommodation space 31 (see FIGS. 2 and 3).

As a result, the stacked tableware P is accommodated from above through the opening 31a on the side of the accommodation space 31 to prevent the tableware from coming off 37, 37, and the stacked tableware P is supported by the bottom support rod 34, which is further supported by the support member 36. By pushing it toward the 36 side, the tableware P can be smoothly rotated to the posture of washing.

By the way, in the conventional tableware basket, for example, the water pressure of the washing water from above pushes the tableware in an inclined posture downward, and the action of trying to get under the tableware in front works, and the tableware in front is lifted. There was something. In addition, depending on the shape and weight of the tableware, it may be lifted by the washing water from below. By lifting the tableware in this way, the next tableware can easily slip under the previous tableware, and if the tableware slips in, it will be difficult for the subsequent tableware to rotate to the upright state. It was sometimes difficult to form a gap for cleaning before and after the tableware. On the other hand, if a lifting member that prevents lifting is installed over the entire stacked tableware so that it comes into contact with the upper edge of the standing tableware, the tableware at any position is pressed by the lifting member in the second posture and lifts. Although it is possible to prevent the next tableware from slipping in, the movement and posture change of the tableware becomes slow, and there is an inconvenience that the storage and removal of the tableware becomes inconvenient.

Therefore, by suppressing the lifting of only the tableware on the front side, the inventors also suppress the lifting of the tableware that is piled up in the standing posture after that, and the tableware does not slip into the tableware at any position and the washing operation is smooth. Found to be continued. From this point of view, the inventors arranged the following regulating member 4 in the tableware basket 3.

Specifically, the tableware basket 3 is a regulating member 4 that regulates the upward movement of only the leading tableware P1 in which the opening surface f is exposed among the plurality of tableware P in the posture of washing the tableware P shown in FIG. It has. The regulating member 4 includes a fall prevention portion 41 attached to an adjusting mechanism 5 described later, and a pair of extending portions 42, 42 attached to both sides of the fall prevention portion 41. In this embodiment and the modified examples described later, the upward movement of only the leading tableware P1 is restricted. For example, the restricting member is the leading tableware P1 and several sheets (2 or 3 sheets) including it. ) May restrict the upward movement of tableware.

As shown in FIGS. 7A and 7B, when the tableware basket 3 takes a posture of washing the tableware P, the first tableware P1 before washing is moved from the first posture. It is intended to prevent the accommodation space 31 from being further inclined due to its own weight. Further, as shown in FIGS. 7C and 7D, the fall prevention unit 41 prevents the leading tableware P1 at the time of washing from falling further forward in the transport direction d from the second posture described later. It is a part to do. The fall prevention portion 41 is a frame material in which a wire rod is bent into a substantially quadrangular shape, and a reinforcing rod 43 is attached to the center thereof in order to increase the rigidity of the fall prevention portion 41.

As shown in FIGS. 8A and 8B, the reinforcing rod 43 is attached to the inner surface side of the fall prevention portion 41, that is, the side in contact with the opening surface f of the leading tableware P1. Therefore, the upper end 43a and the lower end 43b of the reinforcing rod 43 are in a state of being located inside the opening surface f when the front tableware P1 is rotated to the second posture, and the lower end 43b of the reinforcing rod 43 is at the front. It is in a state of substantially facing the inner surface of the lower end portion of the tableware P1.

The fall prevention unit 41 is formed so that when the tableware basket 3 takes a posture of washing the tableware P, the leading tableware P1 supports the lower edge of the leading tableware P1 in the first posture. There is. As a result, the lower edge of the leading tableware P1 is supported by the fall prevention portion 41, so that the plurality of tableware P in the stacked state is the tableware P as shown in FIGS. 7A and 7B. Due to its own weight, the opening surface f of the tableware P can take a first posture in which it is inclined at a desired angle with respect to the vertical direction.

As shown in FIG. 4, in order to create an opening gap between the tableware P that has been rotated during cleaning and is in the second posture and the next tableware P, the fall prevention unit 41 and the top (top) tableware. A tableware moving space 31b is formed between the tableware and the P1. The tableware moving space 31b is a part of the accommodation space 31, and it is desirable that the tableware moving space 31b is specifically adjusted to a space in which two or three pieces of tableware are pulled out by the adjustment mechanism 5 described later.

Further, the fall prevention unit 41 supports the leading tableware P1 pressed to the transport direction d side by the water pressure of the washing water at the time of washing so as to be in the second posture described later, so that the opening surface f of the tableware P is vertical. It is fixed to the guide members 51, 51 along the direction (that is, so that the leading tableware P1 does not fall further due to the washing water W).

As described above, the regulating member 4 is formed at a position where the upward movement of only the leading tableware P1 is restricted while the leading tableware P1 is in the second posture. Such restrictions on the upward movement of the leading tableware P1 can be achieved by the extending portions 42, 42 attached to the upper side of the fall prevention portion 41.

Specifically, as shown in FIG. 6, the pair of extending portions 42, 42 are provided on both sides above the leading tableware P1 when the tableware basket 3 takes a posture of washing the tableware P (specifically). Is a U-shaped frame in which an extending upper side portion 42b is formed (at a position above the center of the tableware P1).

As shown in FIGS. 5 and 6, the pair of extending portions 42, 42 extend so as to spread from the front side in the conveying direction d in which the tableware P is conveyed toward both upper sides of the leading tableware P1. doing. As shown in FIG. 4, the distance B2 between the extending portions 42, 42, the upper side portions 42b, 42b, and the tips 42a, 42a toward the leading tableware P1 is wider than the width B1 of the leading tableware P1. .. It is desirable that the lengths of the upper side portions 42b and 42b are about the same as or longer than the tableware moving space 31b.

With this configuration, as shown in FIGS. 3 and 4, even if the tableware P is supported by the bottom support rod 34 and further pushed toward the support members 36, 36, the extending portions 42, 42 In addition, the leading tableware P1 can pass between the extending portions 42 and 42 without contacting the tableware P1.

Further, the pair of upper side portions 42b, 42b are positioned so as to come into contact with the upper peripheral edge of the leading tableware P1 that stands up when the tableware P is washed. As a result, the leading tableware P1 is located between the pair of extending portions 42, 42 of the regulating member 4 and the support members 36, 36, and in some cases, until all the subsequent tableware P is washed. , It is sandwiched between them, and the movement of up, down, left and right with respect to the transport direction d is restricted.

At this time, since the upper side portions 42b and 42b have a C-shape that expands toward the tableware P side, they are inclined to abut with the edge of the leading tableware P1 and are in contact with the supporting members 36 and 36 at the leading tableware P1. Does not fit. When the pressure on the fall prevention unit 41 due to water pressure is released (that is, when the water pressure on the last tableware P does not work), the first tableware P1 separates from the upper side portions 42b and 42b due to its own weight and tilts quickly. You can return to the first posture you did. Further, since the upper side portions 42b and 42b inclined in a V shape are located at the upper part of the tableware moving space 31b, even if the leading tableware P1 tries to rotate away from the support members 36 and 36 to a position shifted from the support members 36 and 36, It can also be guided to the upper side portions 42b and 42b and guided to an appropriate position.

As shown in FIGS. 5 and 6, the tableware basket 3 is further provided with an adjusting mechanism 5 that adjusts the size of the accommodation space 31 along the direction in which the tableware Ps overlap according to the number of the plurality of tableware Ps. ing. The adjusting mechanism 5 includes a pair of guide members 51 and 51, and a slide member 52 slidably attached to each guide member 51. The slide member 52 can be fixed to each guide member 51 at a predetermined position, and the fall prevention portion 41 of the regulation member 4 is fixed to the slide member 52.

By moving the slide member 52 along the guide member 51, the pair of extending portions 42, 42 are also moved along with the fall prevention portion 41 along the guide member 51, and the size corresponding to the number of a plurality of tableware P. In addition, the size of the accommodation space 31 can be adjusted.

Since the above-mentioned tableware moving space 31b is formed between the tableware P1 and the fall prevention portion 41 in the accommodation space 31, the tableware basket 3 is rotated by 90 °, and the tableware basket 3 moves the tableware P. When taking the washing posture, the lower side of the leading tableware P1 slides on the support members 36, 36 and slips into the tableware moving space 31b. As a result, the opening surfaces f of the plurality of stacked tableware P are inclined in the vertical direction in the first posture.

3. 3. Cleaning of Tableware P Using Tableware Basket 3 First, the storage of tableware P in the tableware basket 3 will be described with reference to FIGS. 2 to 4. As shown in FIG. 2, first, a plurality of tableware P having the same shape and a predetermined number of dishes P are stacked in the same direction so that the opening surface f faces upward.

The storage space 31 of the tableware basket 3 is set to a size that can accommodate a predetermined number of tableware P by adjusting the position (height) of the regulation member 4 by the adjusting mechanism 5. Has been done. When changing the number of dishes P to be washed, the slide member 52 is moved to adjust the position of the regulating member 4 according to the number of dishes P.

Next, as shown in FIG. 2, the tableware basket 3 is arranged so that the opening 31a faces upward. Next, as shown in FIGS. 2 and 3, the stacked tableware P is housed in the storage space 31 from above through the opening 31a, and the stacked tableware P is supported by the bottom support rod 34, which is further supported. Push it toward the members 36 and 36.

In this state, as shown in FIG. 4, the tableware P1 at the head (top) and the tip 42a of the extending portion 42 (upper side 42b) of the regulating member 4 are in a non-contact state, and are at the head (most). A tableware moving space 31b is formed between the tableware P1 in the upper row) and the fall prevention portion 41 of the regulating member 4.

Next, the tableware basket 3 is changed to the posture for washing the tableware P, and the tableware basket 3 is placed on the conveyor 2. Specifically, with a plurality of tableware Ps housed in the tableware basket 3, the tableware basket 3 is rotated by 90 ° so that the opening surface f of the leading tableware P1 faces the transport direction d. Is placed on the chain belt 21 at the entrance 15.

As a result, as shown in FIGS. 6, 7 (a) and 7 (b), the opening surface f of the leading tableware P1 faces in the horizontal direction, and due to the weight of the tableware P, each tableware P has an opening surface f. It is possible to take the first posture inclined with respect to the vertical direction.

In this state, the tableware basket 3 containing the tableware P is sequentially conveyed to each cleaning unit 10. As shown in FIG. 9A, an upper nozzle 11 and a lower nozzle 12 are arranged in each cleaning unit 10, and the cleaning water W of the upper nozzle 11 and the lower nozzle 12 is placed in the tableware basket 3. It is sprayed toward.

Here, in the present embodiment, since the regulating member 4 is provided, first, the leading tableware P1 rotates with the lower edge of the leading tableware P1 in contact with the support members 36, 36 as a fulcrum from the first posture. Move. The rotated front tableware P1 changes from the inclined posture of the first posture to the standing posture of the second posture. In this second posture, the upward movement of the leading tableware P1 is restricted by the extending portions 42, 42 of the regulating member 4 above the leading tableware P1. In some cases, the leading tableware P1 is sandwiched between the supporting members 36, 36 below and the extending portions 42, 42 of the regulating member 4 above the leading tableware P1 (see FIG. 9B). ).

In particular, when the leading tableware P1 is sandwiched, in the present embodiment, the leading tableware P1 is placed below the leading tableware P1 in a state where the leading tableware P1 is in the first to second postures during washing. The leading tableware P1 is stably sandwiched at 3 points or more (specifically, 4 points) by the two supporting members 36, 36 and the pair of extending portions 42, 42 above the leading tableware P1. can do.

As a result, during washing, the second tableware P1 in which the leading tableware P1 stands up is maintained, so that the next tableware does not slip under the leading tableware P1 and the leading tableware P1 does not rise. In particular, the pair of extending portions 42, 42 above the leading tableware P1 can stably suppress the lifting of the leading tableware P1.

As a result, when the washing water W of the upper nozzle 11 is sequentially sprayed on the plurality of tableware P as the tableware basket 3 is transported from the first tableware P1 to the last tableware P stacked, the tableware P becomes the first tableware P. It is sequentially rotated from the posture of No. 1 to the second posture, and a gap is sequentially formed between them. Since the washing water W flows into the sequentially formed gaps, the tableware P can be washed sequentially (see FIG. 9C).

The tableware P of the tableware basket 3 that has passed through one upper nozzle 11 returns from the second posture to the first posture, and further passes through the next upper nozzle 11, the first tableware P shown in FIG. 9A. Maintain the posture of.

In the present embodiment, the leading tableware P1 is in an environment where it is easy to float due to the water pressure from below by the washing water W from the lower nozzle 12, but even in a situation where the washing water W is not sprayed by the lower nozzle 12. When the water pressure of the washing water W of the upper nozzle 11 acts on the upper edge of the tableware P immediately after the first tableware P1, the lower end of the next tableware P slips under the standing first tableware P1. As a result, the leading tableware P1 is likely to come up. Even in such a case, in the present embodiment, the leading tableware P1 that stands up is restricted from moving upward by the extending portions 42, 42 of the regulating member 4, so that the leading tableware P1 floats up. There is no such thing. Then, since the tableware P after that is also in an upright posture so as to fit into the upright leading tableware P1, even if it tries to rise in the same manner, it is locked to the previous tableware and is prevented from floating. ..

Further, in the present embodiment, as shown in FIG. 8B, the lower end portion 43b of the reinforcing rod 43 of the fall prevention portion 41 may be used as the regulating member 4 to prevent the leading tableware P1 from rising. That is, when the leading tableware P1 is in the upright second posture, the inner surface and the lower edge of the lower end portion of the leading tableware P1 are formed with the lower end portion 43b of the reinforcing rod 43 and the support members 36, 36. By being located between the two, it is possible to prevent the leading tableware P1 in the second posture from rising. Depending on the shape and size of the tableware, the lower end portion 43b of the reinforcing rod 43 may be extended downward, or the diameter of the reinforcing rod 43 may be increased. Alternatively, a resin restricting member (not shown) extending toward the inner surface of the lower end portion of the leading tableware P1 may be fixed to the lower portion of the fall prevention portion 41.

As described above, the regulating member 4 of the present embodiment can not only press the upper edge portion of the leading tableware P1 but also suppress the lower side thereof from the inner surface. From this point of view, the extending portions 42, 42 may be omitted, but in the present embodiment, the extending portions 42, 42 are also provided on the upper side of the fall prevention portion 41, so that the leading tableware P1 is more lifted. It can be surely suppressed.

FIG. 10 is a schematic perspective view showing a tableware basket according to a first modification of the tableware basket 3 shown in FIG. In the tableware basket 3 shown in FIG. 10, the regulating member 4 is attached to the frame 32 of the tableware basket 3. If the number of tableware P to be stored in the tableware basket 3 is determined in advance, the adjusting mechanism 5 for adjusting the size of the storage space may be omitted as in the first modification.

FIG. 11 is a schematic perspective view showing the tableware basket 3 according to the second modification of the tableware basket 3 shown in FIG. In the tableware basket 3 shown in FIG. 11, the regulating member 4 is attached to the frame 32 of the tableware basket 3, and unlike the one shown in FIG. 5, the regulating member 4 is not attached to the adjusting mechanism 5.

Specifically, the adjustment mechanism 5 includes an adjustment frame 53 that adjusts the size of the accommodation space 31 along the direction in which the tableware overlaps according to the number of a plurality of tableware, and the adjustment frame 53 is a pair. It is attached to the slide members 52, 52 of. The adjusting frame 53 functions as a support frame for supporting the bottoms of the stacked tableware P, and can be moved along the pair of guide members 51, 51 via the slide members 52, 52. The adjusting frame 53 is a frame material in which a wire rod is bent into a substantially quadrangular shape, and a reinforcing rod 54 is attached to the center thereof in order to increase the rigidity of the adjusting frame 53.

According to this modification, by moving the adjusting frame 53 along the pair of guide members 51, 51, the tableware P is accommodated along the overlapping direction according to the number of the plurality of stacked tableware P to be accommodated. The size of the space 31 can be adjusted.

FIG. 12 is a schematic perspective view of a state in which the tableware P is housed in the tableware basket 3 according to the third modification of the tableware basket shown in FIG. The tableware basket 3 shown in FIG. 12 is provided with a regulating rod 42A installed in an upwardly inclined manner from the front side to the rear side in the transport direction d instead of the extending portion 42 of the regulating member 4. The regulation rod 42A is attached to the tip of the reinforcing rod 43 attached to the center of the fall prevention portion 41 via a hinge 42e.

Although not shown, the regulation rod 42A has a nesting structure, and its length can be adjusted according to the number of stacked tableware P to be accommodated. A locking claw 42d that locks to the bottom support rod 34 is formed at the tip of the regulation rod 42A. Although not shown, the angle of the regulation rod 42A in which the bottom support rod 34 is supported by the locking claw 42d can also be changed according to the number of tableware P.

According to this modification, as shown in FIG. 13A, the regulation rod 42A is rotated to open the accommodation space 31, and the tableware P stacked from the released accommodation space 31 is accommodated.
