Interlayer water-stop tray for house

Abstract

The invention discloses an interlayer water-stop tray for a house. The interlayer water-stop tray for the house is installed at the bottom of a floor and is connected to a through pipe, vertically penetrating through the floor, of an upper water passing device. The interlayer water-stop tray for the house comprises a tray base, a tray connecting piece and an anti-odor valve. The tray connecting piece and the anti-odor valve are installed on the tray base. The tray base comprises a tray body and a drain pipe arranged in the middle of the tray body. The anti-odor valve is arranged adjacent to the drain pipe. The anti-odor valve is a one-way valve. The water outlet of the anti-odor valve is connected to the wall of the drain pipe. The tray connecting piece is installed on the tray body, and connects and penetrates the bottom of the through pipe and the top of the drain pipe. Through the method, the odor escape and backwater phenomenon generated during use can be effectively suppressed, and small animals such as flying insects and ants are prevented from entering the room from a pipeline.

Description

technical field [0001] The invention relates to the field of waterproof pipelines, in particular to an interlayer waterproof tray for houses. Background technique [0002] As a commonly used waterproof device between floors of buildings, the water-stop tray is usually installed at the bottom of the floor partition, corresponding to the water pipe or water area such as the kitchen sink and bathroom facilities, to prevent the water flow along the upper floor due to water pipe bursts or waterproof defects in the water area. The gaps around the drainage pipes directly or infiltrate into the lower room, affecting the work and life of the lower staff. Although the existing water-stop tray has a protective effect, the odor generated in the waste water accumulated in the drain pipe easily diffuses into the room through the overflow hole on the water-stop tray, causing indoor air pollution, and the overflow hole is not closed when not in use. It is not conducive to preventing water ...
