Description

Secondary drainage structure of toilet

Technical Field

The utility model relates to the technical field of toilet drainage, in particular to a secondary drainage structure of a toilet.

Background

The problem of water accumulation in a caisson of a falling-plate type toilet is common in the falling-plate type toilet, and the key of designing a secondary drainage system is to design a drainage system on the same layer. Water accumulation in the caisson may be due to: the water leakage caused by the untight waterproof layer of the toilet floor, the damage and water leakage of a pipeline system in the caisson, the water leakage caused by the untight guide of the joint of the periphery of the floor drain and the floor, the water leakage caused by the untight seal of the joint of the closestool and the floor and the like. The common two-row drainage system has the following disadvantages:

1. the floor drain sets up on the caisson bottom plate, and the horizontal branch pipe of drainage lays in the caisson below, and the secondary drain pipe can't be with the layer, and lower one deck needs local this branch pipe of hidden with the furred ceiling.

2. The side-drainage or bottom-drainage floor drain is arranged, the secondary drainage branch pipe is connected with the sewage vertical pipe, the wastewater vertical pipe or the ventilation vertical pipe, and the secondary drainage system is communicated with the sewage and wastewater pipe, so that the gas cannot be isolated, and the problem of odor return in a toilet exists.

3. The water stopping joint with the secondary drainage function is adopted, so that the problem of odor return of a toilet caused by overflow of gas in a drainage pipeline cannot be solved.

Therefore, it is necessary to provide a secondary drainage structure for a toilet to solve the above problems.
