DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grease strap used for drainage equipment, and more particularly, to a grease strap installed in a drainage system such as a kitchen where oils and fats and sewage are mixed in drainage. .

[0002]

2. Description of the Related Art In a kitchen drainage system, a grease trap for collecting solids such as fats and oils, leftovers, and cooking wastes is provided in a gutter (kitchen floor). Is installed between the main drainage.

A grease trap of this type is provided with a receiving basket (having an infinite number of net-like or small-diameter openings at least at a lower portion thereof) for collecting solids such as leftovers mixed with kitchen drainage, and a drain main pipe. It is provided with a partition plate (having a function of generating an upflow / downflow with respect to drainage from a receiving basket) installed at the entrance, a trap tube, and the like. The operation of the grease trap having such a configuration will be described. First, solids such as leftovers when cooking food is prepared in the kitchen fall on the floor surface, and this is washed down by a kitchen worker by a mop or a watering operation into a drain gutter. Solid matter such as leftovers in the gutter flows in the gutter along with the drainage toward the grease trap, and flows into the receiving basket in the grease trap. Solids such as leftovers are collected by the receiving basket, only drainage flows out, flows into the drainage main pipe via the partition plate, and is finally drained outside the building. In this way, solid matter is collected by the grease trap and does not flow out to the drain main pipe,
No sediment or decay is generated in the drain main pipe and the pipes thereafter.

[0004]

However, in the case of the conventional grease strap, when this is used for kitchen drainage,
There are the following problems.

(1) That is, the layout of the kitchen drainage system often involves several design changes, and the layout does not conform to the initial plan. At present, the drainage trench must be moved. The fitting around the grease strap tends to be complicated. In addition, since the inflow of drainage can usually only be performed from the side of the catch basket (the drainage main can not be attached to the lower side of the grease strap, etc.), it is difficult to examine the fit around the grease strap from this surface. I have.

[0006] (2) The amount of garbage (chips from cooking materials, leftovers, bird heads and feet, crab and shrimp peeled shells, etc.) from kitchens is large, but currently available green Since the size of the strap receiving basket is small for a commercial kitchen, the collection limit is reached in a short time and maintenance and inspection must be performed frequently.

(3) Since the drainage from the grease trap is regulated on the opposite side of the receiving basket, it is difficult to connect with the drainage main pipe. Generally, the priority of the extraction position in the kitchen is
[Kitchen appliance layout> trench layout> grease strap inflow direction> drainage main horizontal position determined by the greatest common divisor of drainage point> grease strap drainage extraction position], so the direction of drainage from the grease strap depends on the kitchen appliance layout, etc. It depends.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a grease strap that can easily fit around a grease strap even if a design change occurs.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a grease strap for preventing oils and fats from flowing into a drain main pipe, which is installed in a floor and sealed. A main body having a water structure, a catcher disposed in the main body to collect solids such as oils and fats supplied together with the drainage, and the catchment which is supplied to the drainage when the incoming wastewater is supplied from any direction. A lid having a shape to flow in and detachably attached to cover an upper part of the main body,
A drain outlet having a plurality of openings which are attached to the inner wall of the main body in close contact with the receiving basket and which can communicate with a drain main pipe, and are disposed between the drain outlet and the receiving basket; And a partition plate to be provided.

[0010] In addition, a discharge valve mechanism can be provided to discharge the deposits to the bottom of the main body.

Further, a cap may be provided for closing an unused one of the drain outlets.

[0012] The lid may be formed into a shape having an inclined surface descending toward the center and an opening at a lower end thereof.

[0013]

According to the above-mentioned means, the lid can be guided to the receiving basket regardless of the direction of the drain outlet in any direction of 360 degrees. In addition, the drainage outlet having a structure not depending on the pipe shape is disposed adjacent to the receiving basket, and has an opening on each side that can communicate with the drainage outlet, so that the outlet position of the drainage is not regulated, and the drainage outlet is located at the lower part. Connection with drainage pipes, and thickness (depth)
Can be made thinner. Therefore, the drainage can be received from all directions, and the restriction on the mounting position of the drainage main pipe can be greatly eased. Therefore, even when the design is changed, it is possible to easily fit around the grease strap.

The discharge valve mechanism provided at the bottom of the main body can discharge the sediment deposited at the bottom, thereby facilitating the cleaning of the inside of the main body and improving the cleanliness of the grease strap.

One of the openings of the drainage outlet is connected to the drainage main pipe, and the other is not used.
Drainage flows out of the drainage outlet through these openings, and cannot be efficiently sent to the drainage main pipe, and the trap function is also reduced. Therefore, if a cap for closing the unused opening is provided, the drainage can be led to the drainage pipe without waste, and the trap function does not decrease. Further, by reducing the size of the portion having the trap function, the capacity of the receiving basket can be increased, and it is possible to cope with a large-scale kitchen.

The lid is formed in a mortar shape having an inclined surface descending toward the center, so that the supplied drainage (in some cases, only drainage, regardless of the direction of the outlet of the pipe or the gutter). If there is a case where solid matter is mixed), the opening provided at the lower end (central part) of the mortar-shaped part allows all the drainage supplied from the pipes and gutters to flow into the receiving basket. . Therefore, even if a design change occurs, it is possible to easily fit around the grease strap.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front sectional view showing an embodiment of a grease strap according to the present invention. The grease strap 1 is installed on the floor 3 of the kitchen by being connected to an end of a drain pipe 2 connected to a gutter provided in the kitchen. The main body 4 constitutes the housing of the grease strap 1, and a receiving basket 5 is arranged in the main body 4 so as to occupy 50% or more of the volume thereof. This receiving basket 5 is designed to have a larger volume than a conventional receiving basket, and its shape is a square trough, and in a certain height range of its lower peripheral surface (it can be provided also on the bottom surface). Micro-sized holes are formed vertically and horizontally at regular intervals.

In the vicinity of the side surface of the receiving basket 5 on the drain side, a detachable partition plate 6 having a height slightly lower than the height of the receiving basket 5 and processed into a shape as shown in FIG. (The opening 6a is formed at the center of the opening.) The partition plate 6 is attached such that both side ends and a lower end thereof are in close contact with the inner wall surface and the bottom surface so that the drainage discharged from the main body 4 can overflow.

On the upper part of the receiving basket 5, a middle lid 7 is detachably provided so as to form a mortar-like shape, open at the center lower end, and cover the upper end of the main body 4. The inner lid 7 is made of a highly corrosion-resistant stainless steel or the like.
An openable / closable handle 8 is attached to facilitate the attaching / detaching operation. Further, on the lower surface of the main body 4, a discharge valve 9 whose built-in valve is opened only when cleaning the inside of the grease strap 1 is attached.

Further, on the inner wall facing the partition plate 6, there is provided a drain outlet 11 for guiding drain water overflowing from the partition plate 6 to a drain main pipe 10 (attached to the outer wall surface of the main body 4). Is provided. As shown in FIG. 3, the drainage take-out portion 11 has a box shape whose depth is smaller than its size.
Inside, a partition plate 14 is provided so as to guide the drainage taken in from a water inlet 12 provided on one surface to a drain main pipe 10 while bypassing the drainage to a drainage port 13 on the other surface. The drainage discharge unit 11 configured as described above has the same function as the S-shaped trap.

It is to be noted that the drain main pipe 10 is mounted so that the drain main pipe 10 can be attached to different places according to design changes.
A plurality of openings 15 are provided at key points where the number is zero, in accordance with the outer diameter of the drain main pipe 10. With such a configuration,
The drain main pipe 10 can be attached as shown by a solid line in FIG. 1 or by a dotted line. The unused opening 15 is covered with a cap 20 made of rubber, vinyl chloride, or the like.

It should be noted that the upper surface should be at the same height as the floor 3 so that there is no problem even if a person rests on the grease strap 1.
A grating 16 (top cover) is detachably provided. In the present embodiment having the above configuration, the drain pipe 2
And the drainage mixed with solid matter (oil and fat, leftovers, cooking material scraps, etc.) from the gutter formed on the floor 3 falls onto the inner lid 7 and passes through the opening provided at the center thereof to receive the basket. 5 flows into. By providing the inner lid 7 in this way, drainage from the gutter and the pipe can be received from any direction.

In the drainage flowing into the receiving basket 5, only moisture flows out into the main body 4 through each of the small holes provided in the lower part of the receiving basket 5, and the solid content mixed in the drainage stays in the receiving basket 5. . The drainage flowing out of the receiving basket 5 overflows the partition plate 6, further flows into the drainage outlet 11 through the water inlet 12, flows around the drainage outlet 11 in an S-shape, and finally drains. It flows out to the mouth 13 and further to the drain main pipe 10.

As described above, by forming the drainage to bypass the inside of the drainage take-out section 11, U (or P, S)
Etc.) While having the same function as the trap, it contributes to downsizing of the drain trap part. Due to this compactness, the size of the receiving basket 5 can be increased, and the maintenance and inspection cycle can be lengthened. The solid matter flowing through the inner lid 7 is collected by the receiving basket 5, but the sludge is settled at the bottom of the main body 4, and is removed periodically (or as needed). There is a need to. In such a case, the discharge valve 9 is opened to remove sludge and fine solids remaining at the bottom of the main body 4.

Next, a maintenance method will be described. First, the grating 16 is removed, and the inner lid 7 is further removed.
Remove. Thereafter, a coagulant is introduced into the receiving basket 5 to solidify the fats and oils floating on the uppermost part in the receiving basket 5 (garbage is retained below the fats and oils), and the fats and oils are solidified. . Next, as shown in FIG. 4, the solidified fat 17 by coagulation is taken out of the receiving basket 5 by the jig 18. Further, the grease strap 1 is taken out from the receiving basket 5, and the garbage 19 accumulated inside is dumped into a garbage bag or the like as shown in FIG. Thus, the receiving basket 5 is taken out and the garbage 1
The process up to disposal of 9 is a daily maintenance management operation.

Further, in the case of periodic maintenance and inspection, for example, monthly maintenance and management, in addition to the same work as daily maintenance and management,
The drainage take-out part 11 is taken out, and as shown in FIG. 6, the cap 20 of the opening not communicating with the drainage main pipe 10 is removed, and the inside and the outside are cleaned by spraying water or the like. Thereafter, the cap 20 is attached to each of the openings 15 that do not communicate with the drain main pipe 10, but is attached to the main body 4 later. Next, the partition plate 6 is pulled out in the vertical direction, and the surface is cleaned by applying water in the same manner. Furthermore,
The discharge valve 9 is opened for the main body portion 4 in which the inside of the main body portion 4 is empty, and the inside of the main body portion 4 is cleaned while water is poured from outside using a water hose or the like. Thereafter, the discharge valve 9 is closed. Further, the drainage extraction unit 11 is attached to a predetermined position, and the receiving basket 5 is installed at a predetermined position. In addition, the cleaned partition plate 6 is inserted into a predetermined position. Thus, the monthly maintenance management work is completed.

In the above embodiment, one basket 5 is mounted on one main body 4, but FIG.
As shown in the figure, a plurality of receiving baskets 5 (in this example, receiving baskets 5a,
5b) to increase the capacity. In this case, as shown in FIG. 8, the number of the inner lids 7 is set to the number corresponding to the number of the receiving baskets 5 (the inner lids 7a and 7b). It can be dealt with by changing. Further, the inner lid 7 does not need to be symmetrical with respect to the center, and may have a structure in which the center is moved according to the amount and direction of drainage flowing into the center.
