Description

Hidden drainer for building

Technical Field

The invention relates to a hidden drainer for a building.

Background

The floor drain of the wet area of the dry-wet separated toilet is the only drainage position.

In the prior art, a plurality of drainage holes on the surface of a floor drain are used for draining water, after the water is drained, a filter screen arranged in the floor drain is used for filtering the water, and then the water is discharged downwards into a drainage pipeline; the filtering mode can meet the drainage requirement when aiming at the drainage with small flow. However, the quality of life of people is improved at present, the shower head adopts a large-flow pressurized shower head, the water yield in unit time is larger, and the floor drain with the traditional structure has lower drainage efficiency because the mesh size of the filter screen is blocked by hairs; meanwhile, the number of the drainage holes on the surface of the water tank is small, so that the drainage efficiency is further reduced. Therefore, during bathing, water can be found to accumulate in the wet area, causing the personnel to fall over. Meanwhile, the traditional sunken floor drain has higher installation requirement when being installed; slight height deviations can result in water accumulation.

Based on the problems, the hidden type water drainer for the building is designed to be larger in draining area, higher in draining efficiency and lower in installation difficulty.

Disclosure of Invention

The invention aims to solve the technical problem of providing a hidden type drainer for a building, which has larger draining area and higher draining efficiency and reduces the installation difficulty.

In order to solve the problems, the invention adopts the following technical scheme:

a hidden drainer for buildings comprises an embedded box body, wherein an opening is formed in the upper end of the box body, an outer edge part is arranged at the top extending edge of the box body, a sewer pipe opening is formed in the bottom of the box body, an inner box body is arranged inside the box body, a convex edge part is arranged on the outer wall of the box body, a sealing strip is assembled on the upper part of the convex edge part, the sealing strip is in contact with the inner wall of the box body and then forms sealing with the inner wall, and a water inlet hole is formed in the outer wall of the inner box body and positioned above the convex edge part; a launching gap is formed between the box body and the inner box body; the bottom of the inner box body is provided with a detachable box cover; a water inlet pipe is arranged at the inner bottom of the box cover; the lower end of the water inlet pipe is downwards inserted into the sewer pipe opening; a plurality of water inlet grooves are annularly formed in the outer wall of the water inlet pipe; an end cover is screwed in the upper end of the water inlet pipe, a plurality of through holes are annularly formed in the outer wall of the end cover, rubber ends are arranged in the through holes, steel wire bristles are inserted into the rubber ends, and the bottoms of the two adjacent steel wire bristles are mutually staggered.

Preferably, an upward convex ring is arranged at the inner bottom of the box body; the bottom of the box cover is provided with an annular groove embedded into the convex ring; the structure realizes the contraposition installation of the box body and the inner box body, and ensures the uniform distance between the outer wall of the convex edge part and the inner wall of the box body; the sealing strip is convenient for sealing in the later stage.

Preferably, an annular slot is arranged at the bottom of the end cover, a filter screen is inserted into the annular slot, and the filter screen is positioned on the inner side of the steel wire bristles; a water gap is formed between the tops of two adjacent steel wire brush hairs; the arrangement of the filter screen increases the water discharge when the water level of the inner box body rises to the position of the water passing gap. In a conventional state, the sewage is filtered and intercepted through the steel wire bristles, but when the sewage amount is large and the water permeation efficiency of the steel wire bristles is insufficient, the sewage can cross the steel wire bristles and then is filtered through the filter screen; the drainage rate is increased, and the filtering effect on drainage is increased; reducing the chance of the sewer line becoming clogged with hair.

Preferably, an inner ring made of rubber is clamped between the water inlet pipe and the end cover, and first steel wire bristles are implanted into the inner wall of the inner ring; the first steel wire brush bristles positioned on the inner wall of the inner ring form a launching gap at the center of the inner ring; a conical water inlet hole is formed in the center of the end cover; above-mentioned technical scheme, mainly be that the efficiency of launching in intake chamber department is not enough, perhaps steel wire brush hair department has bonded too much hair, when leading to launching the efficiency reduction, the water level rises in the inner box body, then accessible toper inlet opening launch the flow, guarantees that there is not obvious ponding above the bathroom ceramic tile. In addition, the water which is discharged from the lower row through the conical water inlet hole needs to pass through the first steel wire brush bristles; to a certain extent, the water is simply filtered on the basis of meeting the drainage requirement. In the structure, the tail ends of the first steel wire brush hairs form a lower water gap; when the water level rises to the top of the end cover, water slowly enters from the outer wall of the conical water inlet hole, and at the moment, a launching gap does not work; when the water level accumulation speed is too high, so that the water drainage efficiency at the gap of the first steel wire bristles is insufficient, the water level can overflow the end cover, and the water drainage efficiency can be increased through the water drainage gap; avoid the bathroom ponding.

Preferably, a water absorption sponge is arranged between the box body and the inner box body and below the convex edge part; the water absorption sponge is mainly used for absorbing water permeating between the box body and the inner box body.

Preferably, the top of the sealing strip is provided with a water guide inclined plane, and the water guide inclined plane is inclined towards the water inlet hole; the water guide inclined plane can increase the water inlet efficiency.

Preferably, the bottom of the sealing strip is provided with an embedding strip, and the top of the convex edge part is provided with an embedding groove for clamping the embedding strip; above-mentioned structure for the sealing strip can be replaced, and the sealing strip is the rubber product, has ageing, therefore above-mentioned structure can be to the sealing strip after ageing replacement.

Preferably, a glue filling groove which transversely penetrates through the top of the inner box body is formed in the top of the inner box body; the ceramic tile needs to be laid in the bathroom, and the glue filling groove can better fix the ceramic tile and the ceramic tile.

The invention has the beneficial effects that:

1) the device is installed in a hidden mode, so that no obvious appearance exposure exists in a wet area, and the design is simpler and more elegant;

2) compared with the traditional floor drain, the device has the advantages that the drainage area is larger, the number of water inlet holes is larger, and the drainage efficiency is higher;

3) the device filters the discharged water by matching the rotatably-taken end cover with the steel wire bristles, so that hairs are prevented from entering a drainage pipeline;

4) in the device, the inner box body can be upwards taken out, so that the interior of the box body can be conveniently cleaned after being taken out, the operation is simple, and the odor is avoided; meanwhile, the box cover can be opened, and the inside of the inner box body can be cleaned after the box cover is opened;

5) the installation area of this device is great, consequently has bigger area of intaking, during the installation, only need simple ground of making level can, the installation degree of difficulty reduces.
