Description

  The present invention relates to a commercial sink installed in a large-scale kitchen where a large amount of food is made, for example, a school lunch, a supermarket, a hotel, an inn, a restaurant and the like.

  The sink provided in the commercial sink has, for example, a plurality of tanks each having a length of 800 cm to 900 cm and an open upper surface, and the adjacent tanks are partitioned in a separated state by the partitions of the sink.

  A drainage device is attached to each tank on the outer bottom surface of the sink. Furthermore, an overflow portion is formed at the longitudinal end portion where the faucet of the sink is not attached, and at the partition portion, a concave portion whose upper surface is opened. These overflows are walls to separate them, ie, an overflow wall that defines the highest water level in the tank, a partition wall that is at the same height as or higher than this wall, and a bottom wall that spans the lower ends of these walls. At least. The bottom wall of the overflow section is located higher than the bottom wall of the tank, and the bottom wall of the overflow section has an overflow outlet. The overflow outlet communicates with the lower part of the drainage device.

  The drainage device drains water directly from the tank located thereabove without passing through the overflow part, and shuts off the drainage and collects the water supplied from the faucet opposed to the tank. You can choose the state. If the water level in the tank located above the drainage device whose drainage blocking state is selected exceeds the maximum water level of this tank, the water supplied from the faucet thereafter will One part overflows the overflow wall over the overflow wall. This overflowing water flows out from the overflow outlet and is drained through the lower part of the drainage device. For this reason, when the drainage blocking state of the drainage device is selected in each tank separated and independent from each other, each tank is placed in the tank under flowing water condition in which water flows separately to each tank. The food material etc. can be washed (this is called individual running water washing). And, for example, when washing with running water for use in a school lunch supply sink, in general, in a state where water is stored substantially full in the tank for running water washing, these water faucets from all the water faucets Approximately 7 to 22 liters of water per minute are supplied to the opposite vessel.

Unexamined-Japanese-Patent No. 10-211042 gazette

  As described above, the conventional business use sink which is configured to enable independent flushing for each tank separately has a rapid progress of the water contamination in the tank accompanying the cleaning of the food. For this reason, when a large amount of food is to be washed with running water, when the operator judges that the water contamination accumulated in the tank has progressed to some extent, the soiled water is drained out of the tank, and thereafter it is contaminated. It is necessary to continue the cleaning work after supplying no new water to the tank after drainage. Thus, there is a problem that the water which is accumulated and soiled in each tank for each tank is drained each time, and as a result, a large amount of water is consumed and it is economically disadvantageous. At the same time, since the washing operation is interrupted with the replacement of water, there is a problem that the workability of the washing is not good when trying to wash a large amount of food in running water.

  An object of the present invention is to provide a business-use sink which can wash objects to be washed in running water while saving water.

In order to solve the above problems, the commercial use sink according to the present invention includes a sink in which a plurality of tanks for cleaning objects to be cleaned are arranged, and one end and the other end of the sink in the longitudinal direction in which the tanks are arranged. And at least one weir separating the baths adjacent in the longitudinal direction of the stream, and the bath provided at the other end of the stream and adjacent to the other end of the stream It is attached to each of the tanks on the outer bottom surface of the sink and is attached to the outer bottom surface of the sink, and is switched between the drainage state and the drainage blocking state. a plurality of drainage apparatus capable comprises.
The overflow section has an overflow outlet in communication with the drainage device attached to the tank adjacent to the other end of the sink, and the weir is of the one end of the sink against the weir It has an intermediate overflow portion which allows flooding from the tank adjacent to the side to the tank adjacent to the side of the other end of the sink relative to the weir,
An intermediate flood height of the intermediate flood section enabling flooding of the tank adjacent to the side of the other end of the sink with respect to the weir, and the tank from the tank adjacent to the other end of the stream It is characterized in that the overflow height which enables the overflow to the overflow section is set lower the closer to the other end of the sink .

  According to the present invention, with water flowing from one end side to the other end side of the sink across all the tanks, the cleaning worker is first required to wash the object to be washed first on the downstream side of the flow direction of water Since the objects to be cleaned can be sequentially transferred to the tank on the upstream side of the flow direction of the water to be cleaned, it is possible to wash the objects to be washed while running water-saving. The effect is that it can be provided.

It overflows beyond the upstream partition wall 21a which defines the overflow height h3. Then, the water received by the overflow portion 21 flows out from the overflow outlet 22 opened in the bottom wall 21 c of the overflow portion 21 into the third drainage pipe line 23 and flows into the lower portion of the third drainage device 20. It flows into the drainage pipe 48 from the outlet 20 b of the third drainage device 20. Thereby, the state where water flows from one end 11 a to the other end 11 b of the sink 11 is secured.

  In such a state of running water, the food which is first to be washed is roughly washed by the washing operator in the third tank 14 which is at the most downstream side in the flow direction of the running water and the progress of the soiling accompanying the washing is fast. Next, the food is transferred from the third tank 14 to the second tank 13 located at the middle position in the flow direction of the flowing water by the washing worker, and the food is washed. Since the food material to be transferred into the second tank 13 has been washed in the third tank 14 before that, the progress of water contamination in the second tank 14 accompanying the washing of the food material in the second tank 13 is slow. Finally, in the first tank 12 which is the uppermost stream in the flow direction of the running water and in which the progress of the soiling accompanying the washing of the food is the slowest by the washing worker, the food which has already been sufficiently washed in the second tank 13. The food is transferred and rinsed in the first tank 12.

  According to such running water washing, the food can be successively transferred to the tank on the flow direction upstream side of the flowing water 11 and washed successively, so that the water in the third tank 14 may be excessively contaminated. Even if it is necessary to replace, in addition to the frequency of replacing water in the second tank 13 becoming low, there is almost no need to replace the water in the first tank 12.

  Moreover, in flush water washing, flush water washing can be performed in a state in which only the first faucet 41 disposed on the most upstream side in the flush direction is opened. At this time, about 7 to 22 liters of water per minute is supplied from the opened first faucet 41 to the first tank 12 opposed to the faucet. In the case of such flush water washing, even if water is not supplied from the second faucet 42 and the third faucet 43, flowing water from the first tank 12 to the third tank 14 is formed, so all the faucets were opened. It is preferable at the point which can carry out a large amount of water saving compared with the case where a running water washing | cleaning is carried out in a state.

  Therefore, according to the sink 1 of the said structure, a large amount of foodstuffs can be washed in running water, achieving water saving as demonstrated above.

  Moreover, the sink 1 of the structure demonstrated above can also perform separate running water washing | cleaning using at least 1 tank of the 1st tank 12-3rd tank 14. FIG. For example, in the individual flush water washing in the first tank 12, the first drainage device 18 is in the drainage blocking state, the first plug 29 is removed, and the first intermediate overflow outlet 27 of the first intermediate overflow 26 is opened. Then, the first water faucet 41 is held in the open state.

  Thus, the water stored in the first tank 12 at a water level lower than the downstream partition wall 26b of the first intermediate flooded portion 26 flows into the first intermediate flooded portion 26 in the first intermediate flooded portion 26 as a first overflow It overflows beyond the upstream partition wall 26a which defines the height h1. Then, the water received by the first intermediate flooded portion 26 flows out from the first intermediate flooded outlet 27 opened in the bottom wall 26 c of the first intermediate flooded portion 26 to the first drainage pipeline 28 and is the first drainage device It flows into the lower part of 18 and is further drained to the drainage pipe 48 from the outlet 18 b of the first drainage device 18. The food material can be washed in running water in the first tank 12 by using the first tank 12 kept in the flowing water state in this manner. Such individual running water washing is suitable for washing a small amount of food.

  Similarly, in the individual flushing with water in the second tank 13, the second drainage device 19 is in the drainage blocking state, the second plug 34 is removed, and the second intermediate overflow outlet 32 of the second intermediate overflow 31 is opened. In the state, the second faucet 42 is held in the open state and performed. As a result, the water stored in the second tank 13 is blocked from flowing into the first tank 12 by the downstream partition wall 26b of the first middle flood part 26, and under this condition, the second middle flood part 31 Overflow the upstream partition wall 31a defining the second overflow height h2 into the second intermediate overflow section 31 and, further, the drainage pipe 48 from the second drainage pipe 33 via the second drainage device 19 The food can be washed with running water in the second tank 13.

  Similarly, in the individual flush cleaning in the third tank 14, since the overflow outlet 22 of the overflow section 21 is held in the open state, the third drainage device 20 is brought into the drainage blocking state, and the third water tap 43 Hold it open and be done. As a result, the water stored in the third tank 13 is blocked from flowing into the second tank 13 by the downstream partition wall 31 b of the second intermediate flooding section 31. Under this condition, the third section 13 Since the fluid overflows into the flooding portion 21 beyond the upstream partition wall 21a which defines the flooding height h3, the water is further drained from the third drainage pipe 23 to the drainage pipe 48 via the third drainage device 20, The food can be washed with running water in the third tank 14.

  Also, using the first tank 12 to the third tank 14 in a state in which the drainage by the first drainage device 18 to the third drainage device 20 is blocked, the first flooding height h1 to the third flooding height h3 or less It is also possible to wash the food while keeping the water in the water level.

  As explained above, the sink 1 of one embodiment selects either the running water washing which can aim at improvement of water saving performance using all the tanks which the sink 11 has, and an individual running water wash, and selects a foodstuff. It can be washed.

  The present invention is not limited to the one embodiment. For example, in the present invention, the number of vessels may be two or four, and the number of weirs varies depending on the number. Further, the present invention is also applicable to the sink 1 of the specification for use on both sides used in a state where the worker stands on both sides in the width direction of the sink 11. In this case, the overflow portion 21 is provided at the longitudinal middle portion of the other end 11b of the sink 11, and similarly, the first intermediate flood portion 26 is provided at the longitudinal intermediate portion of the first weir 16; The middle flood portion 31 is provided at the longitudinal middle portion of the second weir 17. Furthermore, in the application to the sink 1 of the specification for two-sided use, the first faucet 41 is respectively provided at both ends in the longitudinal direction of the one end 11a of the sink 11, and similarly, the second faucet 42 is the first weir The third faucets 43 are respectively provided at both longitudinal end portions 16 and at the longitudinal end portions of the second weir 17.
