Description

Drain trench

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage trench embedded in the bottom of a cooking chamber such as a food service center or a restaurant, and relates to a drainage trench which can prevent a flow velocity drop and a safety accident and can be automatically cleaned.

Generally, in a kitchen such as a large restaurant or a food service station, a plurality of drainage trench units are buried on the floor surface in order to discharge dirt and sewage to a sewer line. As drainage trenches, there is known a structure in which trenches are directly poured into concrete structures, and in recent years, a structure in which a drainage trench of a metal material is buried on the concrete floor surface is widely used.

Hereinafter, a conventional metal drainage trench will be described in detail with reference to the accompanying drawings.

FIG. 1 is a conventional drainage trench disassembly perspective view, and FIG. 2 is a plan view showing a conventional drainage trench mounting structure.

As shown in FIG. 1, the conventional drainage trench includes a main body 10, which is formed in a duct shape having an open upper side so as to serve as a drainage passage and which is seated in a drainage channel made of concrete, And a cover (20) formed to cover the upper opening of the main body (10). A flange 12 having a seating jaw 14 is formed on the left and right side walls of the main body 10. The cover 20 is mounted on the seating jaw 14 at both sides in the width direction.

At this time, in order to drain a large amount of water in a short time, the opening of the main body 10 should be made wide and the through-hole 22 should be made large. In this case, Not only a phenomenon of falling into or engaging with the ball 22 may occur, but also a safety problem such as a foot hanging when the user moves may occur. Also, since the bending strength of the cover 20 is reduced as the width of the cover 20 is increased, there is also a disadvantage that the cover 20 may be easily deformed and damaged.

When the flow rate of the sewage flowing into the main body 10 is small, the main body 10, which is applied to the conventional drainage trench, is constructed of a flat duct having a flat bottom. The flow velocity is lowered, and foreign matters may be accumulated.

Hereinafter, embodiments of a drainage trench according to the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 are an exploded perspective view and a perspective view of a drainage trench according to the present invention.

The drainage trench according to the present invention is a type of drainage facility installed on the floor of a space where water is frequently used, such as a restaurant or a foodservice station, to discharge sewage or small dirt. It is characterized in that it is constituted. That is, the drainage trench according to the present invention comprises a main body 100 inserted into a drainage channel recessed at the bottom of a building structure and serving as a channel for sewage and dirt, And a washing water splash tube 200 for sweeping dirt to the washing water spray pressure. The first feature is that the main body 100 is formed in a circular tube shape.

When the main body 100 serving as the channel of the sewage is formed in the shape of a circular pipe, the sewage introduced into the main body 100 collectively flows on the bottom of the main body 100, It is possible to obtain an effect that the frictional resistance is reduced. That is, the sewage flowing in the circular tube-shaped main body 100 has a lower frictional resistance with respect to the bottom of the main body 100 as compared with the case where the bottom of the main body 10 (see FIGS. 1 and 2) Even if the amount of the sewage water flowing into the main body 100 is small, it is possible to smoothly flow the sewage and foreign matter.

In addition, when the cross section of the bottom of the main body 100 is formed in a concave shape, the sewage water flow rate is higher than that in the case where the bottom of the main body 100 is flat, even if the flow rate of the main body 100 is the same. It is possible to obtain an effect that the discharge of sewage and dirt is smoothly performed.

The drainage trench according to the present invention is also characterized in that the width of a portion where sewage and dirt are introduced is narrowed so as to prevent the wheels of the car or the user's foot from being caught or caught. That is, the main body 100 included in the drainage trench according to the present invention is formed in the shape of a slit 102 in which the upper opening through which sewage and dirt is introduced extends in the longitudinal direction of the drainage, And a pair of flanges 120 extending in a direction away from the upper ends of the pair of vertical walls 110. The vertical walls 110 and the pair of vertical walls 110 are connected to each other. At this time, it is also possible to provide a method in which the flange 120 is directly coupled to both ends of the slit 102 in the width direction without the pair of vertical walls 110. However, since the flange 120 is provided at both ends in the width direction of the slit 102 When the flange 120 is directly coupled, the thickness of the concrete structure on which the flange 120 is seated is reduced, so that the body 100 may not be stably fixed. Therefore, it is preferable that a vertical wall 110 is provided between the slit 102 and the flange 120 as shown in the present embodiment.

As described above, in the drainage trench according to the present invention, the portion into which the sewage and the dirt are introduced is made narrow so that the wheels of the car are caught in the portion where sewage and dirt are introduced, It is advantageous not to be. Particularly, when the washing water distributing pipe 200 is installed in any one of the vertical walls 110 (in this embodiment, the left vertical wall 110) of the pair of vertical walls 110, The width of the portion into which the sewage and the dirt are introduced becomes narrower because only the narrow space between the vertical wall 200 and the right vertical wall body 110 can be introduced into the main body 100. As a result, And the effect that the user's feet are not stuck can be increased.

The conventional drainage trench is constructed such that sewage flows into the through hole 22 formed in the cover 20 so that the sewage flowing between the adjacent two through holes 22 does not flow down below the cover 20, (20). In other words, in the case of using the conventional drainage trench shown in FIGS. 1 and 2, all of the sewage supplied to the drainage trench can not be introduced into the drainage trench, and some of the drainage trenches may be crossed over to the opposite side. However, in the drainage trench according to the present invention, since the space through which the sewage flows is formed in the shape of one slit 102 over the entire length of the drainage trench, the drainage provided to the drainage trench can not be passed to the drainage trench, . That is, when the drainage trench according to the present invention is used, the effect of discharging sewage and dirt is remarkably improved.

The conventional drainage trench is required to have a separate cover 20 because the upper side opening of the main body 10 is wide. However, since the upper side opening of the drainage trench according to the present invention is narrow, There is a difference that it is not necessary. If such a separate cover is not required, the cost of manufacturing the cover can be reduced, so that the manufacturing cost of the drain trench can be reduced, and the repair cost and replacement cost incurred when the cover is damaged or broken can be reduced It is possible to expect the advantage of saving.

5 and 6 are a cross-sectional view and a longitudinal sectional view of the drainage trench according to the present invention.

The drainage trench according to the present invention is a drainage trench which is connected to the drainage trench and the drainage trench 200 by a distance between the vertical wall body 110 (right vertical wall body 110 in this embodiment) When the dirt is introduced, if the spacing space is deformed or narrowed, the drainage can not be performed smoothly. The drainage trench according to the present invention is provided with a plurality of drainage trenches 200 coupled between the vertical wall 110 and the washing water distributing pipe 200 so that the spacing space between the washing water distributing pipe 200 and the vertical walling 110 can be maintained constant. And an interval holder 300 is provided.

The gap fixing table 300 is formed in a square pipe shape so as to have a high compressive strength and bending strength with respect to weight, and both longitudinal ends thereof are coupled to the vertical wall body 110 and the washing water distributing pipe 200. On the other hand, if a step is formed between the upper surface of the flange 120 and the upper surface of the gap fixing member 300, an impact may be generated when the guide wheel is pivoting on the gap fixing member 300, . Therefore, it is preferable that the upper surface of the gap fixing table 300 is disposed to coincide with the upper surface of the flange 120 as shown in FIG.

The washing water distributing pipe 200 is also formed to have a rectangular pipe shape so as to have a high bending strength and the upper surface of the washing water pipe 200 is arranged to coincide with the upper surface of the flange 120 Do. In this embodiment, only the structure in which the gap fixing table 300 is mounted on the upper part of the washing water distributing pipe 200 is shown. However, the upper and lower sides of the washing water distributing pipe 200 are uniformly pressed The gap fixing table 300 may be mounted on the upper side and the lower side of the washing water distributing pipe 200, respectively. In addition, the height of the gap fixing member 300 and the height of the washing water distributing pipe 200 may be set to be the same so that the washing water distributing pipe 200 can be more stably fixed.

The main body 100 included in the present invention is installed such that the longitudinal direction thereof is directed horizontally or slightly inclined toward the drainage direction. When the flow rate of the sewage flowing in the main body 100 is not large, There may be a case where foreign matter stays on the floor of the main body 100 without flowing down along with the sewage. As a result, the foreign matter on the bottom of the main body 100 is adhered to the bottom of the main body 100 with time, and the main body 100 is periodically required to be internally cleaned.

In order to perform manual cleaning of the inside of the main body 100, there is a problem that it takes a lot of time and a lot of time. Therefore, the drainage trench according to the present invention includes a washing water distributing pipe 200 for automatically washing the bottom of the main body 100, wherein the injection nozzle 210 of the washing water distributing pipe 200 vertically downwardly discharges washing water The cleaning liquid injected through the injection nozzle 210 is not rapidly drained and remains in the main body 100 for a certain period of time, so that the effect of discharging foreign substances is somewhat deteriorated.

In order to solve such a problem, the drainage trench according to the present invention is installed diagonally so that the injection nozzle 210 of the washing water distributing pipe 200 injects the washing water in a sloping direction along the sewage flow direction inside the main body 100 . The spray angle of the spray nozzle 210 is appropriately set according to various conditions such as the size of the main body 100 and the washing liquid injection pressure.

Meanwhile, when the disinfectant is provided by the washing water distributing pipe 200, the washing water distributing pipe 200 may be used for disinfecting the inside of the main body 100 by injecting the disinfectant into the main body 100 at a high pressure have. In addition, when the high-temperature compressed air is supplied to the washing water distributing pipe 200, the washing water distributing pipe 200 may be used to dry the inside of the main body 100. That is, the type of fluid supplied to the washing water distributing pipe 200 can be changed into various kinds of fluids according to the user's choice, and a detailed description thereof will be omitted.

7 is a plan view showing a mounting structure of a drainage trench according to the present invention.

7, when the drainage trench according to the present invention is mounted on the floor as shown in FIG. 7, since the width of the space through which the sewage is introduced is very narrow, there is less concern that the wheel of the car is caught, Since the space is formed to be long in the longitudinal direction of the drainage trench (left and right direction in FIG. 7), it flows into the drainage trench even if the drainage flows to any site. At this time, as the width of the space through which the sewage flows is narrow, the wheels of the truck are caught, and there is less concern of people's feet being caught. Therefore, the width of the space into which the sewage is introduced is preferably set to 2 cm or less. However, if the width of the space through which the sewage is introduced is too narrow, the sewage and the dirt may not flow normally. Therefore, the width of the space through which the sewage is introduced is suitably set according to various conditions such as the type of sewage and dirt.

In addition, since the drain trench according to the present invention has a very small area exposed to the outside as compared with the conventional drain trench (see FIG. 2), it is also advantageous in that the appearance is improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
