Description

A kind of floor drain

Technical field

The present invention relates to drainage structures field, specifically one be embedded at ground, bottom and connect with drainage pipeline Floor drain.

Background technology

Floor drain is the important interface connecting sewerage system and flooring, be often applied to toilet, bathroom or Balcony, the quality of its performance directly affects the quality of room air.The drainage speed of floor drain, odor-resistant result, easy to clean and anti- Stifled performance is the principal element affecting its using effect, and at present frequently with the mode deodorant of fluid-tight, inner part uses and detachably connects The mode connect with easy cleaning, arrange between panel with outlet together with filter screen to avoid the deposit such as hair blocking outlet Or drainage pipeline, and in order to ensure the strainability of filter screen, frequently with densely covered circle or the filter screen of regular polygon network. It is disclosed in the utility model patent on January 22nd, 2014 at China Authorization Notice No. CN 203403489 U, authorized announcement date A kind of floor drain, its structure includes drain cover, floor drain body, water storing vessel, leak pipe and button bowl, and floor drain body and water storing vessel, to detain bowl equal Use metal material；Water storing vessel is threaded connection with floor drain body, and its middle and upper part is provided with uniform leaking hole；The pipe that leaks is suspended on In the middle of water storing vessel, the pipe bottom that leaks extends bottom water storing vessel；Being provided with support muscle inside button bowl, surface is one layer of metal net shaped knot of detailed catalogue Structure, in floor drain body, portion is provided with two hasps, and button bowl can be installed by being rotated on floor drain body of handle or be unloaded.This invention interior Portion's structure convenient disassembly, the cleaning of the most each parts, button bowl is relatively big with the contact area of current, can effectively increase the stream of draining Speed, but, current can show stronger tension force under detailed catalogue metallic netted structural, thus affects the flow velocity of draining, and hair is also Easily blocking detailed catalogue metallic netted structural.

Summary of the invention

For problem above, it is an object of the invention to provide a kind of anti-blocking property is good and floor drain that draining is fast.

For reaching above-mentioned purpose, the present invention takes techniques below scheme:

A kind of floor drain, the screen plate including panel, being arranged at panel centre position, the drainage chamber being fixedly connected on lower panels, It is connected to the water seal cup of bottom, drainage chamber and removably connects with water seal cup and be limited in the water seal in the middle part of water seal cup Inner core, screen plate is provided with the drainage slotted eye of lattice-shaped, and the middle and upper part of water seal cup has outlet, and described drainage intracavity sets Being equipped with the defecator of a shell structure, described defecator is by the upper filter screen of hemisphere cavity structure and hemisphere cavity structure Lower filter screen composition, described upper filter screen has the slotted eye A along axis of symmetry directional spreding, described lower filter screen has along cross section The slotted eye B of annular outer wall directional spreding.

Wherein, the lower end in described drainage chamber is provided with interior step, and all sides at the maximum outside diameter of described defecator are arranged There is the outer step coordinated with interior step clearance.

Wherein, described upper filter screen removably connects with described lower filter screen.

Wherein, it is provided with carrying handle in the middle part of the upper surface of described upper filter screen.

Wherein, described slotted eye A and described slotted eye B is bar shape trench hole.

Wherein, the bottom of described water seal cup is hemisphere cavity structure.

The invention have the advantage that internals easy accessibility, it is convenient to clean, the wire side up and down that upper filter screen forms with lower filter screen The defecator being staggered in length and breadth, had both had sufficiently large water flow section to guarantee drainage speed, had had again stronger interception longer The ability of hair is to prevent blocking, very useful.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of floor drain, the screen plate 2 including panel 1, being arranged at panel 1 centre position, the company of fixing The drainage chamber 3, the water seal cup 4 being connected to bottom, drainage chamber 3 that are connected on panel 1 bottom and removably connect also with water seal cup 4 Being limited in the water seal inner core 5 in the middle part of water seal cup 4, in the present embodiment, water seal inner core 5 is shelved on the inner convex platform 42 of water seal cup 4 On, to facilitate arrangement and to take out.It is provided with the drainage slotted eye of lattice-shaped on screen plate 2, the foreign material such as hair are carried out ground floor Filtering, in water seal cup 4, upper position has the outlet 41 uniform along the whole body.

Further, in drainage chamber 3, the defecator 6 of a shell structure it is provided with, by the upper filter screen of hemisphere cavity structure 61 and the lower filter screen 62 of hemisphere cavity structure form, in particular, upper filter screen 61 has the groove along its axis of symmetry directional spreding Hole A611, lower filter screen 62 has the slotted eye B621 of the annular outer wall directional spreding along its cross section, and is bar shape trench hole, as This, upper filter screen 61 and lower filter screen 62 form the filtration in cross pilotaxitic texture with vertical gradient, both enhance filtration The ability of the foreign material such as hair, does not the most affect drainage speed.

The lower end in drainage chamber 3 is provided with interior step 31, and all sides at the maximum outside diameter of defecator 6 are provided with and interior step The outer step 63 of 31 matched in clearance, on the interior step 31 in defecator 6 is shelved on drainage chamber 3 during use.

For convenience of the cleaning of the inside and outside layer of defecator 6, upper filter screen 61 uses, with lower filter screen 62, the mode removably connected, The present embodiment uses threaded.It addition, be provided with carrying handle 612 in the middle part of the upper surface of upper filter screen 61, to facilitate defecator 6 Take out in drainage chamber 3.

The bottom of water seal cup 4 is hemisphere cavity structure, can effectively prevent bottom from piling up bigger miscellaneous of silt isodensity Thing, is also convenient for the cleaning of inside.

When the present invention uses, current are usually whirlpool after flowing to drainage chamber 3 and flow to form, first pass through the hemisphere of evagination state The upper filter screen 61 of body cavity structure, due to foreign material appearances such as hole shape and the perforate direction of slotted eye A611, the hairs of slightly larger volume Easily being blocked in the downside of upper filter screen 61, hereafter current flow through the lower filter screen 62 of hemisphere cavity structure of concave configuration, to logical Cross the foreign material such as hair of upper filter screen 61 to carry out the interception again of different angles and filter, greatly improve the mistake of larger volume foreign material Filter ability, and vertical gradient distribution filtration there is sufficiently large water flow section, little to the resistance of current, it can be ensured that Water velocity, internals easy accessibility, it is beneficial to overall comprehensive cleaning, very useful.
