Description

Drainage system for bathroom {piping system for bethroom}

The present invention relates to a drainage system of a bathroom made by applying integrated trap means for a sink, a bath and a bathroom floor.

In general, a bathroom is provided with a sink, a bathtub, a toilet, and a water supply system for supplying water to each of these appliances and a drainage system for discharging sewage from each appliance and the bathroom floor.

Conventional bathroom drainage system, as shown in Figure 1, each drain pipe 12, 22, 32 connecting the sink 10 and the bath 20 and the bathroom floor 30 and the drainage cross pipe (5) ), And respective trap means for preventing the odor gas and the like backflowed from the drainage vertical pipe (not shown) to flow into the drainage pipes 12, 22 and 32 via the drainage horizontal pipe 5; It consists of

As a trap means applied to the drain pipe 32 of the bathroom floor 30, a trench trap 34 buried under the drain hole of the bathroom floor 30 is used, and the trench trap 34 is a kind of water collecting tank. As a structure, the water flowing from the drain of the bathroom floor 30 is stored in a certain amount, and only the excess amount of water is allowed to flow down.

In addition, unlike the trench trap 34, a so-called seal trap type trap means for sealing a certain amount of water in a closed pipe is applied to the sinks 10 and the drain pipes 12 and 22 of the tub 20. .

Here, as a trap means applied to the drainage pipe 12 of the sink 10, the sink 10 is received at the top of the sewage flows from the top to the bottom of the bathroom floor 30, and sealed and discharged downward S trap 14 is applied (in some cases, P trap may be applied), and as a trap means applied to the tub 20, the tub 20 is in contact with the bathroom floor 30 due to the characteristics of the bathroom floor ( It is installed at a lower position than 30) to receive the sewage flowing in from the top to the bottom and P trap 24 is applied to discharge to the side.

On the other hand, according to the drainage system of the conventional bathroom including each of the trap means, various problems are caused due to the characteristics of the trap means and the overall piping factor, which will be described below.

First, the trench trap 34 has a high construction cost due to a complex structure including a water collecting container, and is difficult to install because it is mounted in a manner of being embedded in a floor slab. The trap 14 and the trap P (24) has a problem in that it is not easy to maintain a stable water sealing action because a phenomenon of self-siphon (phenomena in which the water in the trap is sucked out to the drain pipe side) is likely to occur.

Particularly, in the case of the P trap 24 used in the bathtub 20, it is realistic to have a seal depth of about 12 mm in the floor slab structure of a multi-family house, while at least 35 mm to maintain a proper trap function. As the above-mentioned seal depth should be set, it can be said that the functional stability is greatly reduced.

On the other hand, when the drainage action is made in the drainage pipe, the air is compressed or aspirated to generate a positive pressure or a negative pressure. When the fluctuation range of the pressure exceeds a certain value, the seal in the trap is destroyed and the trap loses its function.

Therefore, the inside of the drainage pipe communicates with the atmosphere so that the air in the pipe can escape or the air is supplied to the pipe according to the pressure fluctuation, thereby reducing the air pressure fluctuation width in the pipe, thereby requiring a ventilation structure to maintain the trap function stably. do.

Conventionally, the ventilation structure applied to the drainage system of the bathroom includes an individual ventilation system, a loop ventilation system, a new ventilation system, etc., each ventilation system is provided with a separate vent pipe for each trap, and each vent pipe communicates with the atmosphere. As to be connected to the vent pipe, all of the drainage system has a high stability due to the stable aeration characteristics, but there is a disadvantage in terms of construction cost and space utilization.

The loop ventilation method is to vent two or more traps collectively, and there is a difference in the allowable flow rate from each individual ventilation method, but it is vulnerable to the self siphoning phenomenon.

New ventilation system has the advantage of simple construction and simple construction as it is a method of venting through the new authentic pipe which extends from the top of the drain vertical pipe and is open to the air without installing a separate vent pipe. However, the negative pressure relieving function is poor, and the ventilation effect is properly made only within a certain length from the drainage pipe, so it can be regarded as suitable for small apartment houses.

In consideration of each ventilation method as described above, in terms of ventilation stability, each ventilation method or loop ventilation method is more advantageous than the new ventilation method. However, in recent years, high-rise apartment houses have recently considered construction efficiency. The situation is adopting the new ventilation system.

Accordingly, the bathroom drainage system of the high-rise apartment house, as mentioned above, each trap means configured in the sink (10), the tub 20 and the drainage pipes 12, 22, 32 of the bathroom floor 30 and It is generally made of a combination of the new ventilation system, according to this, there is a problem in that the construction is complicated, as each trap means is provided separately, so that the construction efficiency is low, and the stability of the trap function is also reduced.

The present invention is to solve the above problems, by including an integrated trap means for performing an integrated trap action for the drainage pipe of the sink, bath tub, bathroom floor, simplifying the piping configuration, construction efficiency and trap action To provide a bathroom drainage system that improves the stability of the.

The drainage system of the bathroom according to the present invention, which is provided to achieve the above object, is connected to each drain pipe connected to each appliance and bathroom floor drain in the bathroom, and connected to the respective drain pipe to lead to the drain vertical pipe. And an integrated trap means for integrally performing a trapping action on each of the drain pipes by blocking the odor gas flowing back from the drain pipe and the odor gas flowing back from the drain pipe.

The integrated trap means forms a drain port downward, a main body forming a plurality of connection ports of a branched shape upward, an elbow tube rotatably connected to each drain port of the main body, the drain of the main body It is configured to include a sealing means for selectively sealing the port, the one elbow pipe is connected to each of the drain pipe, the other elbow pipe is made of a sealing unit is installed in a structure that is connected with the drain vertical pipe.

The main body of the sealing unit is a 'U' form, consisting of a structure to form a seal depth more than 35mm at one end.

The sealing means includes a sealing cap that is detachably coupled to the drain port of the main body by a screwing method, and a packing disc fitted to the inside of the drain port so that the sewage introduced into the main body does not come into contact with the sealing cap. Is done.

The packing disk has a center portion, a rim portion formed around the outer circumferential surface of the center portion and thicker than the center portion and curved downwardly, and a close contact portion spaced up and down as protruding outwardly from the rim portion, and downward from the center of the center portion. It includes a fixing protrusion formed to protrude.

The sealing cap is formed with a ring-shaped support jaw supporting the packing disc in a state mounted to the drain port, and a protrusion groove into which the fixing protrusion is fitted.
