Description

Technical field

The technical solution relates to a liquid odor trap that can be used in air-conditioning ventilation, ventilation, exhaust hoods or sewage systems to prevent backflow.

BACKGROUND OF THE INVENTION

At present, the most common siphons are used as odor closures. The drain pipe is submerged in the waste liquid to prevent backflow of air at the sewer pipe. The newer type is a U-bent pipe and the drain pipe is situated above the U-bend in which the waste liquid is held. In air conditioning and ventilation systems, simple non-return valves are used, which are swiveling in the direction of the flowing air and blocked in the opposite direction. The electric control uses blind systems where the blinds are closed and opened by means of a rod and thus the air flow is allowed or not. These systems are not entirely perfect and also have their drawbacks in terms of failure or drying out of water and thus contaminating the space with odor from the pipeline.

The essence of the technical solution

These drawbacks are overcome by a solution according to this utility model, the essence of which is that the liquid odor closure is formed by a main part which is tightly closed from the top by a lid. The side walls of the main part are equipped with a branch for connection to the sewer pipe and a water inlet. The main part may have a circular cross section or a rectangular cross section in the transverse direction. From the bottom of the main part opposite the age is situated the air supply duct. The air intake duct extends into the interior of the main body and is provided with an air outlet to the sewer duct at the branch, the opening being in the same position as the branch. A closure is located on the pipeline in the interior of the main part, with at least three guide rails between the pipeline and the closure to allow the closure to move smoothly along the pipeline. The closure and the pipe correspond in shape to each other. The closure is made of a material that floats on the water, its bulk density being so low that the buoyancy of the air during suction lifts it above the surface of the liquid to such an extent that it unlocks an opening into the sewer, for example of polystyrene. Water supply 1 to the interior of the main part is provided, for example, from a toilet flushing cistern or other dispensing device. Excess water is discharged to the sewer pipe via a branch.

Examples of technical solution

The liquid odor closure comprises a main part 1, which is tightly closed from the top by a lid 2. The side walls of the main part 1 are provided with a branch 3 for connection to the sewer pipe and a water inlet 4. The main part 1 may have a circular cross-section or a rectangular cross-section in the transverse direction. An air intake duct 5 is situated from the underside of the main part 1 opposite the lid 2. The air inlet duct 5 extends into the interior of the main body and is provided with an air outlet opening 6 into the sewage duct from the branch 3, the opening 6 being in the same position as the branch 3. wherein at least three guide rails 8 are provided between the conduit 5 and the closure 7 to allow the closure 7 to move smoothly along the conduit 5. The closure 7 and the conduit 5 correspond in shape to each other. The closure 7 is made of a material that floats on the water, its bulk density being so low that the buoyancy of the air during suction lifts it above the liquid level to block the opening to the sewer, for example of polystyrene. The water supply to the interior of the main part 1 is provided, for example, from a toilet bowl flushing unit B or from another dispensing device. Excess water is discharged to the sewer line via branch 3.

Below is an example of the use of a liquid odor closure, which does not limit its use in other cases. The example according to figure 4 works in such a way that when the ventilator A is started, the odor is extracted from the space of the toilet bowl B and air duct 5 through the liquid odor trap. The air pressure lifts the closure 7, its stability being ensured by three guide rails 8 and the air outlet opening 62 is unlocked, through which it is led through the branch 3 into the sewer line. When the ventilator A is turned off, the closure closes the duct 5. When the water from the flush tank of the toilet bowl B is triggered, the liquid is filled through the spout 4, the excess water being drained from the liquid odor closure via a branch to the sewer.
