Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage groove buried in the floor of a commercial kitchen, a food factory or the like.

[0002]

2. Description of the Related Art In commercial kitchens and food factories, it is important to cook and process food in a clean environment. For that purpose, the commercial kitchen and the food factory must be kept clean at all times. In order to maintain such a clean condition, hygienic maintenance of the drainage system is of utmost importance, and general public supervision is becoming strict.

However, as shown in FIGS. 9 and 10, a groove 21 having a substantially rectangular cross section is formed on the floor surface forming a part of the drainage system of a conventional commercial kitchen or food factory. 21
A step portion 23 on which the lattice lid 22 is placed is formed at the edge of the. The floor surfaces 24 on both sides of the groove 21 are set so as to descend to the groove 21 with a gentle slope.
The food leftovers and the like that have fallen to the inside are introduced into the groove 21 through the grid 25 of the grid lid 22 with cleaning water or the like, collected in the basin, and then drained to the outside.

[0004]

However, the above-mentioned lattice lid 2 is used.
2 and the gap 26 between the stepped portion 23 of the groove 21, and the grid lid 2
Food lattices and the like are clogged in the second grid 25, and by self-digesting them, they become a culture medium of bacteria and the bacteria propagate and spoil to give off a bad odor. Then, the worker or the like who walks on the lattice lid 22 uses the propagated bacteria for the floor surface 2 other than the groove 21.
By moving to 4, the bacteria will propagate throughout the room, and due to scattering, there are many opportunities for bacteria to easily attach to foods placed on food shelves, tables, etc. It promotes food spoilage and increases the risk of food poisoning.

Further, since the groove 21 is made of concrete itself, the surface of the groove 21 has a rough surface so that food residues and the like are easily adhered, and the adhered food residues and the like are self-digested. In this case, as in the above, the bacteria become a good medium and the bacteria grow, and the grown bacteria scatter in the room, which promotes the spoilage of foods and increases the risk of food poisoning.

Further, as described above, since the surface of the groove 21 is a rough surface, it is difficult to completely remove the food residue left over by a brush or the like even during cleaning.

The present invention has been made in order to solve the above problems of the prior art, and an object thereof is to provide a drainage groove having a groove structure which reduces the chances of bacterial growth at low cost.

[0008]

[Means for Solving the Problems] (1) A narrow groove opening formed along the axial direction is opened upward to form an inner wall surface of a smooth surface in which a floor portion provided under the floor surface is curved. A groove main body having, and a groove introducing portion having an inner wall surface of a substantially vertical smooth surface provided so as to rise from both end edges of the groove mouth of the groove main body and form a narrow and narrow opening on the floor surface. The groove introduction portion has a difference in vertical length at one end in the length direction and a vertical length at the other end, and the difference in the vertical length gradually increases from one end to the other end. The drainage groove is formed so as to change toward the end of the drainage groove.
(2) A substantially vertical groove introduction portion provided so as to rise from both edges of the groove mouth of the groove body and form a narrow and narrow opening on the floor surface, and extends outward from the upper end of the groove introduction portion. And a substantially vertical groove introduction part that is continuous to the floor surface that is bent at a gentle slope and is formed, and the outer wall surface of the groove body and the substantially vertical groove introduction part, and the substantially horizontal groove introduction part.

[0009]

In the above structure, the drainage flowing after cleaning the equipment in the room and flowing it to the floor surface and cleaning the floor surface from the horizontal groove introduction part along with the floor slope along with food leftovers etc. Water is guided to the groove body through the vertical introduction part and is drained to the outside. At this time, since the inner wall surfaces of the introduction portion and the groove body are smooth surfaces, frictional resistance is small, and food leftovers and the like are smoothly discharged to the outside without stopping. Further, the opening along the floor surface of the groove and the groove introducing portion leading to the groove is narrow and does not hinder the walking of the worker even if the lid is not covered, and there is room for bacteria to propagate in the opening. Since the workers do not walk, bacteria are not transferred to the floor by walking, and the room is kept clean at all times.

The general manufacturing method of the drainage groove 2 is as follows.
m) narrowed upward along the axial direction (eg, 25 mm)
1 is manufactured by cutting out the opening of FIG. 1, and a horizontal groove introduction portion 7 in which a horizontal width portion (for example, 30 mm) is separately formed from a ready-made stainless steel plate, Bending so as to have a vertical groove introduction portion 6 forming a vertical wall, and at a distance (for example, 5000 mm) from one end to the other end in the length direction on the vertical wall, By providing a difference (for example, 75 mm) in height from the horizontal width portion, that is, a bent portion, a gradient is formed from one end of the vertical wall to the lower edge of the other end (for example, 75/50).
00) added to the pair of symmetrical horizontal width portions 7 shown in FIG.
a component corresponding to the horizontal groove introduction part 7 composed of a and 7b and a vertical groove introduction part 6 composed of a vertical wall is manufactured, and then along the opening edge of the component part corresponding to the groove body 4. It is achieved by welding 8 a lower edge having a slope and a receiving portion from one end of the constituent portion corresponding to the groove introduction portion 6 to the other end.

In the above manufacturing method, instead of notching a narrow opening above the ready-made stainless pipe, one cut line is provided above the ready-made stainless pipe along the axial direction, As shown in FIG. 6, it is also possible to fold the cut line portion upward to provide a groove opening 5 and butt weld the welded portion 4a, 4b with the inclined lower edge.

As another method of forming the drainage groove 2,
The pipe-shaped groove main body 4 and the folded-back portions 4a and 4b rising on both side edges of the groove opening 5 are integrally formed from a single stainless steel plate, and the groove-introduced portion 6 having the slope is formed in the folded-back portions 4a and 4b.

It is also possible to continuously bend the vertical groove introducing portion 6 and the continuous horizontal groove introducing portion 7, respectively.

The drainage groove 2 may be formed as an integral elongated member having an axial length extending from upstream to downstream, but a plurality of divided drainage members are sequentially connected in series to form a long length. Sometimes it is a scale. Especially when the room is large, the drainage groove 2 is constructed by the latter connection method.

As described above, the use of stainless steel as the raw material for the respective constituent parts of the drainage groove 2 (the groove main body 4, the groove introduction portions 6, 7) is for discharging food leftovers and the like from the kitchen floor surface 1 to the outside. This is because the surfaces, wall surfaces and inner surfaces of the drainage grooves 2 are made smooth in order to reduce the frictional resistance between the food residues and the like and the drainage grooves 2.

Further, narrowing the opening 9 of the groove opening 5 and the groove introduction portion 6 with respect to the diameter of the groove main body 4 makes the structure of the drainage groove 2 which does not hinder the walking of the worker without the lid. This is because the structure of the lid and the fitting step portion of the lid (see FIGS. 9 and 10) serving as a culture medium for bacteria is positively omitted.

In constructing the drainage groove 2, as shown in FIG. 3, when the reinforcing bar 10 of the floor 1 is assembled, a supporting frame composed of the leg portion 11 and the receiving portion 12 is also incorporated to form the receiving portion. 12, the slope of the groove body 4, the groove opening 5 and the opening 9 of the groove introduction portion 6
After setting the respective positions to appropriate values, the concrete 14 is driven in to give a gentle gradient to the surface of the concrete 14 and finish the horizontal groove introduction portion 7 continuously. The receiving portion 12 may be fixed in advance to the groove body 4 of the drainage groove 2 by welding or the like, or the receiving portion 12 may be installed in advance during construction, and the groove body 4 may be installed on the receiving portion 12. By providing the receiving portion 12, the horizontal groove introducing portion 7 is aligned with the floor surface FL to facilitate the burying work.

The drainage groove 2 can also be installed in the existing drainage groove 15. In that case, as shown in FIG. 5, after setting the gradient of the groove main body 4, the position of the groove opening 5 and the opening 9 of the groove introducing portion 6 in the existing drainage groove 15 through the support frame 13, respectively, are properly set. The concrete 14 is poured into the existing drainage groove 15, and the surface of the concrete 14 is continuously finished to the existing floor surface FL and the horizontal groove introduction portion 7 at a gentle gradient.

At the upstream end of the drainage groove 2, as shown in FIG. 4, the groove opening 5 of the groove main body 4 is located at a depth of 25 mm below the floor surface FL, and the groove introduction portion 6 above the groove opening 5 is located. The drainage of food residues and the like on the sloped portion 1a on the upstream side of the floor 1 is configured to flow into the opening 9, and the opening of the groove introduction portion 6 is formed on both left and right sides of the entire length of the drainage groove 2 from the upstream side to the downstream side. The left and right rims of the floor 9 are configured so that drainage of food leftovers and the like on the left and right slope portions 1b and 1c of the floor 1 flows into the rim 9, and
The downstream end of the is connected to the basin buried under the floor surface FL.

The basin 3 comprises an upper water collecting basin 16 and a lower draining basin 17. The downstream end of the drainage groove 2 is connected to the side of the water collecting basin 16, a grid-like lid 18 is capped on the upper side, and the detachable strainer 1 is on the lower side.
9 is attached and faces the upper part of the drainage basin 17 below.

The drainage basin 17 has the strainer 1 on the upper side.
It is connected to the lower side of the water collecting basin 16 via 9 and the side is connected to the outside.

The grid-like lid 18 has a slope portion 1d on the downstream side of the floor 1 and right and left slope portions 1b, 1 adjacent to the slope portion 1d.
It is configured so that the waste water such as food leftovers of c can flow in.

The groove body 4 of the drainage groove 2, the groove introduction portion 6,
Although each constituent part such as 7 is made of stainless steel as a raw material, it is not limited to stainless steel as long as each constituent part has a smooth surface, and other raw materials such as synthetic resin can be selected.

The drainage groove 2 may be formed by successively joining a plurality of concrete blocks (not shown). In this case, the groove wall surface is formed by each concrete block itself to form a smooth surface. The smooth surface can be formed by adjusting the cement ratio or by polishing the groove wall surface, but a synthetic resin pipe can be fitted in each concrete block, or a synthetic resin sheet can be lined. .

Further, in the embodiment, the cross-sectional shape of the groove body 4 is circular, but it is not limited to this, but the lowermost portion is shown in FIGS. 1, 3, 5, 5 and 6. 8
As shown in (1), the U-shaped curved smooth surface allows smooth collection and flow of the residual food and discharged water.

Next, the operation of the above-mentioned embodiment will be described.

When water is sprayed on the surface of the floor 1, the slopes 1a, 1b, 1c, 1 of the floor 1 on which food residues and the like are attached are attached.
d is washed with the sprayed water, and the water becomes drainage mixed with the washed food residues and the like, passes through the horizontal groove introduction portion 7 of the drainage groove 2, and has a narrow narrow width. Water is collected in the opening 9 of the book. At this time, the vertical groove introduction portion 6
Has a difference in vertical length between the upstream end of one end and the downstream end of the other end in the longitudinal direction, and by making the groove main body 4 have a slope, drainage is performed at the inclined portions of the floors 1b and 1c. Groove 2
The drainage water can be collected into the groove main body 4 from anywhere in the opening 9 without providing an inclination in the longitudinal direction, and the surface of the floor can be constituted by a simple inclined surface.

Since the opening 9 is not covered with a lid, the drainage flows directly from the opening 9 into the vertical groove introduction portion 6 and is guided to the vertical inner wall surfaces 6a and 6b, and the groove opening 5 is formed. And then flows into the groove body 4.

At this time, since the surfaces of the horizontal groove introducing portion 7 and the inner wall surfaces 6a and 6b of the vertical groove introducing portion 6 are all smooth surfaces, the resistance to food residues and the like is reduced during cleaning drainage. It does not stop, and is easily transferred to the groove body 4.

The drainage in the groove main body 4 is collected in the water collecting basin 16 due to its gradient. At this time, the groove main body 4 preferably has a circular cross-sectional shape, and by providing a smooth surface, food residues and the like are unlikely to stay on the peripheral surface and are collected at the lowest position, and the U-shaped curve is formed even at the lowest position. Therefore, the resistance is reduced and the water is easily flown into the water collecting basin 16 and the sanitary effect is great.

The waste water collected in the water collecting basin 16 is filtered by a strainer 19 for food residues and the like, dropped into the water discharging basin 17, and then discharged to the outside.

Since the inside of the groove main body 4 is a smooth surface, when cleaning, the main body 20a of the cleaner 20 having the flat shape and along the cross section of the groove main body 4 shown in FIG. 6 is inserted into the groove main body 4 and rotated by 90 degrees to form the handle portion 20.
All the inner walls in the groove body 4 can be easily cleaned by grasping b and moving it from the upstream side to the downstream side of the opening 5.

[0038]

As described above, in short, according to the present invention, the groove having the inner wall of the smooth surface provided below the floor surface is formed by opening the narrow groove opening formed along the axial direction upward. Drainage because it is composed of a main body and a groove introduction section having an inner wall surface of a smooth surface provided so as to rise from both side edges of the groove opening of the groove main body and form a narrow and narrow opening on the floor surface. The floor cleaning wastewater guided into the groove flows into the groove main body of the drain groove without stopping food leftovers or the like in the narrow groove introduction portion of the drain groove, and even in the groove main body. There is no room for bacteria to flow into the basin without stopping. Therefore, unlike the conventional case, the labor for removing the groove lid and the cleaning labor for rubbing the inner wall of the groove can be omitted to facilitate the cleaning, and since the operation for removing the lid can be omitted, bacteria are not scattered. For workers working on the floor, the opening of the narrow groove introduction part not only does not hinder walking, but it may become a breeding medium for migrating bacteria during walking. A small amount keeps the room clean, and food and the like are handled hygienically.
