Abstract

The present invention relates to a sanitary ware, particularly a toilet bowl having air suction and exhaustion function. A air suction machine and a plate type check valve is arranged in a space designed on front end of the cultivate toilet bowl, an open door is arranged on the shell of the relative position of the toilet bowl, when it is opened, the air machine valve assembly integrated with the check valve and the air suction machine are fetched out or pushed in, the inlet of the air suction machine and the air suction passage connect with cavity of the urinal center through strip type air suction port, the air suction passage is close to the previous loop water spraying passage but not connected with the same, the water spraying passage connects with the cavity via the water spraying port. The toilet is maintained clear in air when defecating by using air exhausting structure integrated with the toilet bowl, which discharging bad smelly air into the downcomer.

Description

Band is bled automatically, anti-foul smell flows backwards, direct water closet to the exhaust of water seal hypomere

Technical field:

The present invention relates to a kind of sanitaryware, particularly a kind of water closet that has the pump drainage airway dysfunction.

Background technology:

Washroom in the Modern Residence is luxurious day by day, but blemish in an otherwise perfect thing is: the foul smell that produces at one's leisure in the washroom, have only by foul smell to be dispersed into whole washroom, enter public air channel by the washroom exhaust fan again and enter atmosphere and solve.The foul smell of excrements generation is forced to own " enjoying " earlier like this, drains really a kind of helpless thing again.

At present existing a kind of patent is to utilize to be provided with on toilet lid to bleed exhaust plant; Link by external exhaust hose and to arrange smellyly outside window, this also is good method, especially need not change existing water closet, invest less, but inconvenient be the exhaust of need external hose, influential to the toilet space moulding.Washroom to not near the window is equipped with certain difficulty.

Summary of the invention:

The present invention is that directly a kind of outward appearance of manufacturing is the same with common water closet, but has row's foul smell function, and need not additionally increase stack installs, do not influence the toilet space moulding, utilize and the incorporate a kind of structure of bleeding of water closet, enter sewer pipe with the foul smell that is about to produce at one's leisure the people, make the washroom when defecation, still keep with fresh air.

The present invention is achieved by the following technical solutions:

Band is bled automatically, anti-foul smell flows backwards, direct water closet to the exhaust of water seal hypomere, air exhauster and board-like check (non-return) valve are laid in space of Front-end Design at water closet, on the shell of water closet relevant position, stay a mouth door, can take out or push the blower fan valve member of air exhauster and check (non-return) valve one after opening, bleed fans entrance place and aspirating unit, communicate with urinal center pelvic cavity by the strip air entry, aspirating unit is adjacent with original ring-type water spray road but do not communicate, and the water spray road communicates with pelvic cavity by water jet.The exhaust duct that increases newly links to each other with board-like check (non-return) valve by elastic sealing gasket, and forward intersects outlet with the exit formation of original S shape water sealing (sealing water) pipe.The human body sensor that drives induced draft fan work as inductive switch is set in the water closet front end outside.Bleed and air exhauster inlet joins.

Advantage of the present invention and effect are:

1, start air exhauster automatically, Starting mode has induction type and microswitch formula circuit power to be taken to civil power 220V to use to the 5-12V direct current through step-down rectifier, and circuit and control system are set to strong water proofing property, guarantees safety, and it is also unaffected to scrub urinal.

2, air exhauster has continuous operation, and enough pumping performances are arranged, and blower fan adopts centrifugal.

3, have one reliably between air exhauster and water seal downstream blow-off pipe, unidirectional plate valve conveniently finishes the people, the bath defecation; Air exhauster is bled and is postponed 5-10 and shut down after second, and one way valve is closed automatically, prevents that the sewer foul smell from flowing backwards.

4, different with ordinary porcelain water closet parts are except that be provided with the air exhauster position in the bottom, outside check (non-return) valve and the exhaust duct position, inboard ring-like air intake passage and the bottom air exhauster that also has suction hole and communicate with it joins in the bedpan of top, and this ring-like aspirating unit has dual mode:

A, a ring-type road is set separately above drain is adjacent, air-breathing, bath mutually noninterfere, parallel simultaneously the use.

B, with the shared passage of drain, but one float-ball type automatic valve is arranged in the total air-breathing entrance that communicates with exhaust fan, when bath, hydraulic pressure holds up ball float, blocks air-breathing inlet, anti-sealing pours exhaust duct, bath finishes; Ball float falls, and aspirating unit is open-minded, more than two kinds be reliable with a but make and acquire a certain degree of difficulty.

5, maintenance should be able to be installed and take out to hidden exhaust fan and check plate valve assembling device below urinal easily, and the better elastic sealing is arranged between aspirating unit and exhaust duct, with anti-gas-leak.

6, the exhaust duct outlet is installed in S type blow-off pipe exit, is designed to forward intersect, and prevents that sewage is splashed into exhaust duct.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present invention;

Fig. 2 is components A of the present invention-A sectional view.

The specific embodiment:

Below in conjunction with the accompanying drawing illustrated embodiment the present invention is further described:

Core concept of the present invention is that the special pipeline that the direct suction of foul smell is located in the water closet is entered in the blowdown main of water seal hypomere, conveniently finishes simultaneously, and when exhauster quit work, the check (non-return) valve on the exhaust duct cut out automatically, prevents that foul smell from flowing backwards.

The pump drainage gas course of work of water closet is as follows: human body is near water closet, sensor (16) perception, the driving switch circuit, open centrifuge air exhauster (2), go up some air entries (11) by aspirating unit (15) and will be pumped into negative pressure state in the water closet pelvic cavity, foul smell enters aspirating unit (15) by air entry (11) in the fresh air air bag band pelvic cavity of outside, pressurize through air exhauster (2), open board-like check (non-return) valve (3), through exhaust duct (4), outlet (5) enters supply mains under the blowdown of S shape (sewer pipe has communicating pipe to lead to atmosphere) again.

When the people leaves water closet, sensor (16) driving switch circuit postpones to shut down in some seconds, and board-like check (non-return) valve (3) is by spring and the effect of electromagnetism leverage, reliably closes valve and stops that foul smell flows backwards to aspirating unit (15) by exhaust duct (4) in the sewer pipe.

When water spray road (14), sparge pipe (7) water filling, because water jet (13) is down, air entry (11) is last, and is dislocatedly distributed, and air entry can not blocked, and former water seal liquid level (12) remains unchanged by gutter (9) for water tank (8).

Induced draft fan, the structural relation of board-like check (non-return) valve composite member is:

Locate to join with air exhauster inlet (18) in aspirating unit (10), (15), air exhauster (17) is centrifugal, and the air channel is eccentric shape.The air exhauster startup while board-like valve block of tractive magnet (22) adhesive (19) is pulled to be opened, groups of springs (21) compression, and rubber seal (20) locates to occur passage, and air-flow enters exhaust duct (4) through passage from outlet.Whole air exhauster is packed into behind the water closet bottom, utilizes elastic rubber fitting (23) to withstand on the mouth end sealing of exhast duct (4).

Electromagnet when blower fan stops (22) discharges, under groups of springs (21) effect, and board-like valve block and sealing ring (20) pressing draught excluder air flue.
