Description

A kind of floor drain

The utility model relates to a kind of waste water dewatering installation, particularly relates to a kind of floor drain.

In the prior art, floor drain adopts cast iron to make mostly, and the cast iron color and luster is rust, and not only outward appearance is not good enough, and rough surface, easily gets rusty, and is not easy to clean.A kind of deep water seal deodorant floor drain is disclosed among the Chinese patent ZL92216661.7, traditional grid type floor drain is improved, it comprises that floor drain body, envelope bowl and drain cover constitute, the envelope bowl directly is bearing in the water sealing (sealing water) pipe upper end of floor drain body, perhaps fixedly hang on drain cover, its weak point is: (1) sewage leaking when flowing into floor drain body from drain cover, occupied most of zone of drain cover below because of the envelope bowl, the envelope bowl top so sewage must be flowed through, year in and year out, meeting incrustation on the envelope bowl end face, and produce foul smell; (2) for avoiding envelope bowl incrustation, just need often cleaning envelope bowl, troublesome maintenance; (3) the envelope bowl is independent, consume material, cost up; (4) the drain cover grid is bigger, not anti-cockroach; (5) outlet pipe on the floor drain body is positioned on the center line of floor drain body, is difficult to be applicable to that sewer pipe leans on the situation of corner or wall partially.

The purpose of this utility model provide a kind of attractive in appearance easy to clean, can avoid two degree incrustation, floor drain simple in structure.

The utility model is realized by following technical measures: it comprises floor drain body, envelope bowl and drain cover, wherein, the bottom of floor drain body has downward outlet pipe, the part that outlet pipe extends upwardly in the floor drain body is a water sealing (sealing water) pipe, the upper port of drain cover and floor drain body matches, it is characterized in that: the envelope bowl is integrated with drain cover, one pipe box is set below drain cover, this pipe box is bound by drain cover and forms the envelope bowl, when drain cover covers the upper port of floor drain body, the envelope bowl just is enclosed within the water sealing (sealing water) pipe top in the floor drain body, can form water seal in floor drain body, and the foul smell in the isolated sewer pipe is outwards overflowed; Leaking hole on the drain cover is arranged in the position beyond the envelope bowl region.

As further improvement of the utility model, can suitably control the leaking hole size on the drain cover, leaking hole is a circular hole, diameter is in the scope of 3-10 millimeter, to prevent the discrepancy of cockroach.The stronger big cockroach of vitality is because of the volume leaking hole of can't coming in and going out greatly, though little blackbeetle can pierce in the floor drain body from leaking hole, can because of its vitality a little less than, and be drowned in the water seal in floor drain body.

As further improvement of the utility model, for fear of imperforate section ponding, can make the upper surface at this position form the conical surface, by declivity around the mind-set in the drain cover at the drain cover middle part, this conical surface can be extended to the edge from the drain cover center, also can only limit to the aporate area of drain cover.

As further improvement of the utility model, hemispherical can be made in the floor drain body middle part, the location bias of outlet pipe, promptly the axis of floor drain body is departed from the axis of outlet pipe, so that adapt to the situation that sewer pipe leans on corner or wall partially.Be technologic reason, the also corresponding biasing of water sealing (sealing water) pipe in envelope bowl on the drain cover and the floor drain body.

As further improvement of the utility model, on the diagonal at four angles that the floor drain body upper port forms to extending, the stiffener muscle is set all around, to reduce the distortion that in production process, forms.

As further improvement of the utility model, floor drain body and drain cover are made by cast iron enamel.

The utility model compared with prior art has the following advantages: (1) deodorization: because envelope bowl of the present utility model and drain cover are connected as a single entity, have avoided envelope bowl incrustation and produced foul smell, and removed the hardship of the amid reek and squalor envelope bowl of cleaning from; (2) because the envelope bowl is integrated with drain cover, only need one-shot forming to make, saved these parts of envelope bowl, both simplified structure reduced cost, and easier cleaning; (3) anti-cockroach: the leaking hole on the drain cover limits its size, can prevent the discrepancy of big cockroach, and the water seal liquid level then can be drowned little blackbeetle; (4) because the middle part of floor drain body is hemispherical, and its spherical outline can be suitable with the sewer pipe of different tube diameters, its applicability is wider; (5) water sealing (sealing water) pipe biasing even lean under the situation of corner or wall partially at sewer pipe, still can directly link to each other with sewer pipe, and reach overall appearance; (6) adopt enamel material can make floor drain have the intensity of cast iron and the anti-corrosion stain resistance of enamel concurrently, and surface color is good, easy to clean, and can has abundant colors to select,, reach the overall appearance in room so that arrange in pairs or groups mutually with the decoration floor tile in room.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the main pseudosection of first embodiment of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the main pseudosection of second embodiment of the present utility model.

That illustrated in figures 1 and 2 is first embodiment of the present invention, it comprises floor drain body 1, envelope bowl 4 and drain cover 2, wherein, the middle part of floor drain body 1 is hemispherical, its upper end round mouth is square to extending into outer rim all around, the bottom has downward outlet pipe 3, and the part that outlet pipe 3 extends upwardly to floor drain body 1 inside is a water sealing (sealing water) pipe; Drain cover 2 is circular, matches with the round mouth of floor drain body 1 upper end; Envelope bowl 4 is integrated with drain cover 2, one circular pipe box promptly is set under drain cover 2, this pipe box is bound by drain cover 2 and forms envelope bowl 4, when drain cover 2 covers the upper port of floor drain body 1, envelope bowl 4 water sealing (sealing water) pipe 3 tops that just are enclosed within the floor drain body 1, can form water seal in floor drain body, the foul smell in the isolated sewer pipe is outwards overflowed; Leaking hole 5 on the drain cover 2 is arranged in the position beyond envelope bowl 4 regions, along the circumferential direction evenly arranges, and Circularhole diameter is 5 millimeters.For the ease of moulding, it is coniform that circular hole slightly becomes.Floor drain body 1 and drain cover 2 are made by the cast iron enamel material.
