Description

Concealed floor drain

Technical Field

The utility model relates to the technical field of toilet drainage, in particular to a novel drainage technology for a concealed floor drain.

Background

The bathroom in the north is designed to be double-layer waterproof, and a hidden floor drain is independently arranged between the two layers of waterproof to drain the accumulated water in the filling layer and prevent the upper layer from damaging the accumulated water in the filling layer. If the hidden floor drain is blocked in the construction process, the hidden floor drain cannot be cleaned. The water accumulation in the filling layer is gradually increased for a long time, so that the outer wall of the toilet is easy to be damp and moldy, and peculiar smell is generated. When the upper waterproof layer is not damaged, the hidden floor drain can be dried for a long time and cannot form a water seal effect, so that the odor return condition can be caused. Therefore, a novel drainage technology of the hidden floor drain in the toilet is needed, and the problem that the traditional hidden floor drain generates peculiar smell can be solved while accumulated water in the toilet is drained.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the novel hidden floor drain provides a toilet hidden floor drain drainage technology which is convenient to install, accurate in positioning, capable of discharging accumulated water in a toilet filling layer and solving the problem of peculiar smell generated by a traditional hidden floor drain, and suitable for drainage construction operation of toilets and rooms which are likely to generate accumulated water and return odor.

In order to realize the purpose, the novel hidden floor drain is realized by adopting the following technical scheme:

novel hidden floor drain, including direct-burried floor drain, trap, foraminiferous nozzle stub, direct-burried floor drain is by direct-burried floor drain under subsection, interpolation sleeve constitute, direct-burried floor drain under the subsection be straight cylindric siphunculus, its lower extreme inboard sets up the ring channel, sets up location portion on the inner wall of ring channel, the foraminiferous nozzle stub of inserting in the upper end of location portion, trap is connected to the bottom of location portion, the upper end and the interpolation sleeve of foraminiferous nozzle stub link to each other, set up the comb hole on the interpolation sleeve.

Furthermore, an extruded sheet with a diversion trench is laid at the upper end of the lower part of the direct-buried floor drain, and the direction of the diversion trench of the extruded sheet is consistent with the direction of the main slope.

Furthermore, a water filtering layer is paved on the periphery of the extruded sheet, and aluminum foil paper is paved on the water filtering layer.

Furthermore, an inspection opening is formed in the bottom end of the trap.

Furthermore, the annular groove is filled with sand and ash.

Further, the trap is of a P-type or an S-type.

Compare novel dark floor drain's beneficial effect with traditional technique and do: novel hidden floor drain, it is that the independent research of dark floor drain drainage construction operation of bathroom proposes to, and the drainage standpipe is shared with bright floor drain (being interpolation sleeve) to the hidden floor drain (being directly-buried floor drain lower subsection) among the novel hidden floor drain to adopt foraminiferous nozzle stub to connect in the middle of the bright and dark floor drain, be convenient for discharge in the filling layer ponding and can guarantee that dark floor drain lower extreme trap keeps the water seal for a long time, solve the traditional hidden floor drain of bathroom and produce the peculiar smell problem, wholly have following advancement:

1. the drainage effect is better: the hidden floor drain and the bright floor drain are positioned at the same position, the slope layer of the light and dark floor drain in the toilet finds the slope to the same point, the drainage is more concentrated, the problem of secondary drainage of the structural plate is solved, and the accumulated water in the filling layer is prevented from flashing to the wall body and the doorway part;

2. prevent that dark floor drain from producing the peculiar smell: the trap is additionally arranged on the lower side of the hidden floor drain, so that the problem of peculiar smell in a toilet is solved, and the use environment of the toilet is more comfortable;

3. construction cost reduction: compared with the traditional technology, the hidden floor drain technology can economically achieve the purposes of reducing cost of materials and reducing cost of manual installation of corresponding parts;

4. installation and can shorten installation period convenient to: compared with the traditional technology, the hidden floor drain technology combines a hidden floor drain and a visible floor drain on two branch vertical pipes in a toilet on one branch vertical pipe, is convenient to install, and can reduce the construction amount of the drainage pipeline in the toilet, thereby achieving the effect of shortening the installation period of the drainage pipeline in the toilet.

5. The construction quality is improved: compared with the traditional hidden floor drain technology, the novel hidden floor drain technology reduces a reserved hole on a toilet structural plate, and correspondingly reduces the water leakage probability of a floor slab; and in the work progress, because of the dark floor drain lower extreme adds the reason of installing the trap in the novel dark floor drain technique, if the dark floor drain takes place to block up in the work progress, the inspection socket of detachable trap bottom carries out the inside inspection mediation clearance of floor drain, will trap inspection flap after the clearance is accomplished resume screw can, convenient and fast.
