Abstract

The utility model relates to a deodorizing and sealing device for a drain pipe of a washing basin. An overflow tee is arranged between a washing basin and a water preserving bent pipe, and the overflow tee is connected with the washing basin and an overflow hole by an overflow pipe and a sealing member. One end of the overflow tee is inserted into the water preserving bent pipe so as to form water seal. The overflow pipe of the washing basin is arranged on the upper part of a water preserving pipe bend, and one deodorizing water preserving pipe bend is shared by the overflow pipe and a drain pipe. The deodorizing and sealing device for a drain pipe of a washing basin has the advantages of simple structure, easy processing, less material input and convenient installation and maintenance, and can be suitable for a single washing basin or a plurality of side-by-side washing basins. The drain pipe can be arranged at the lateral side of the lower part of the washing basin so that occupied space is less and a utilizable area and space are increased.

Description

The odour seal device of pot sink gutter

The utility model relates to a kind of odour seal device that is applicable to the pot sink gutter.

In the prior art, the odour seal device of single pot sink gutter mostly is the odour seal device that has U font trap; The gutter odour seal device of two pot sinks mostly is internal and external casing formula odour seal device side by side, and an internal and external casing formula odour seal device is installed below each pot sink, two odour seal devices is coupled together with T shape pipe again.And the bleed off pipe of pot sink does not have deodorization apparatus mostly.Along with the upgrading of product and the raising of quality of life, people press for the gutter that also has deodorization apparatus on the bleed off pipe, to improve environmental quality.The utility model also is to the further improvement of my No. 992360358 " the odour seal device of pot sink gutter " patents and perfect.

The purpose of this utility model aims to provide a kind of rational in infrastructure, simple, and fabrication and installation are convenient, and the odour seal device of the pot sink gutter of dependable performance is to overcome the deficiencies in the prior art part.

Press the odour seal device of a kind of pot sink gutter of this purpose design, comprise the trap and the gutter thereof that communicate with pot sink, its architectural feature is to be provided with the overflow threeway between described pot sink and the trap; The overflow threeway links to each other with the spout hole of pot sink by bleed off pipe and seal; One end of overflow threeway inserts in the trap and constitutes water seal.

Described trap is U-shaped trap or internal and external casing trap.Described gutter is the L shaped gutter of single pot sink or two pot sink T shape gutter.

The bleed off pipe of this pot sink is arranged on the top of trap, with the shared deodorization trap of gutter, it is simple in structure, handling ease, materials are less, and installation and maintenance are all more convenient, applicable to single or a plurality of side by side pot sinks, it can be installed in gutter the avris of pot sink below, and it is less to take up room, and available area and space are increased.

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

Fig. 1 is the odour seal apparatus structure schematic diagram of two pot sinks;

Fig. 2 is the plan structure schematic diagram (dwindling) of Fig. 1;

Fig. 3 is the A-A section structure for amplifying schematic diagram among Fig. 2.

Fig. 4 is the odour seal apparatus structure schematic diagram of single pot sink;

Fig. 5 is the plan structure schematic diagram of Fig. 4;

Fig. 6 is the left TV structure schematic diagram (removing bleed off pipe) of Fig. 4.

Referring to Fig. 1-Fig. 3, be provided with overflow threeway 2 between pot sink 1 and the trap 3; The overflow threeway links to each other with the spout hole of pot sink upper limb by bleed off pipe 4 and seal 5; The lower end of overflow threeway 2 is inserted in the internal and external casing trap 3 and is constituted water seal.The upper end of internal and external casing trap 3 is connected sealing by pipe nut 8 and conical seal ring 7 with the overflow threeway, and the lower end is provided with sealing ring 9, is convenient to cleaning maintenance back sealing.Adopt T shape gutter 6 to be communicated with both sides trap 3 between two pot sinks.Drainage direction is shown in arrow among the figure.

The odour seal device of single pot sink of Fig. 4-shown in Figure 6, its gutter 10 is L shaped, other structure is identical with two pot sink structures.

Trap can also be the U-shaped trap except that being the internal and external casing.Overflow threeway, trap and gutter are the engineering plastics injection mo(u)lding.
