Abstract

The utility model discloses a closet without odour, which mainly solves the insufficiency that the existing closet can not exhaust odour in time. The closet without odour is provided with a seat type or a squat type closet, annular flushing paths are distributed on the periphery of the upper edge of the closet, the flushing paths are communicated with one end of a flushing pipe, the other end of the flushing pipe is provided with a flushing valve, the flushing pipe is also communicated with an air inlet pipe which is connected to an exhaust pipe by an induced fan, and the exhaust pipe can directly extend out of a room or is connected to an odour removal filter. The closet without odour has the advantages of simple structure, reasonable design, convenient installation and economical use. The closet without odour can efficiently suppress the diffusion of odour after users ease nature, and the indoor environment can be purified.

Description

Closet without odour

The utility model relates to the closet in the indoor toilets, is meant a kind of Closet without odour that smell comes out that suppresses especially.

At present, the closet that install indoor toilets the inside mostly is common seat formula or squatting pan greatly, and during excrements, the foul smell of generation can be dispersed in the room air people simultaneously, and is both unhygienic, also makes the people be difficult to stand in the closet of this no odor removal.The baneful influence that produces in order to destroy foul odors, people place aromatic, deodorant in the washroom, or exhaust fan is installed.But aromatic, deodorant just improve indoor smell, can not destroy foul odors, and change room air with exhaust fan, because of its air flue is big, air draft pressure is little, needs to discharge a large amount of air, could satisfy the needs of deodorizing, also can lose indoor a large amount of heat energy in winter, and power consumption consuming time, lose more than gain.More than these all are the removing measures of taking again after foul smell diffusion, belong to the act of mending the fold after the sheep is lost in fact.

The purpose of this utility model is exactly will provide a kind of simple and reliable for structure, installation and use cost is cheap, can effectively stop foul smell to the indoor Closet without odour that distributes.

For realizing this purpose, the Closet without odour that the utility model is designed, comprise original formula or crouching formula urinal, this urinal upper edge circumferential distribution has annular water flushing channel, water flushing channel communicates with an end of jet water spout, the other end of jet water spout is provided with the flushing valve that opens and closes the water source, its main points are that this jet water spout also links with an end of an air inlet pipe, the other end of air inlet pipe and the import of induced draft fan link, the outlet and the stack of induced draft fan link, stack can directly stretch out outdoor, so that foul smell is discharged to outdoor.Or on stack, connect an odor removal filter, be emitted on the cleaned air behind the filtration deodorization indoor.

Advantage of the present utility model is: utilize water flushing channel and jet water spout thereof around being distributed in the existing urinal, the foul smell that produces in the time of will defecating by induced draft fan is directly discharged outdoor, or is emitted on indoorly by odor removal filter, and it is simple in structure, easy for installation, be easy to transform existing closet.Its air flue is little simultaneously, and air draft pressure is big, and it is concentrated, timely, thorough to extract or purify foul smell, has suppressed foul smell effectively and has distributed, and has guaranteed that IAQ (indoor air quality) is good.And its induced draft fan Miniaturizable, noise is low during work, and indoor heat-energy losses is little, and power consumption is few, and is very economical and practical.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is the structural representation of a kind of formula Closet without odour.

Fig. 2 is the structural representation of another kind of seat formula Closet without odour.

Fig. 3 is a kind of structural representation of the formula Closet without odour of squatting.

Seat formula Closet without odour as shown in Figure 1, has more pond 1 of a formula, urinal 1 upper edge circumferential distribution has annular water flushing channel 4, and water flushing channel 4 communicates with an end of jet water spout 5, and the other end of jet water spout 5 links with the flushing valve 10 that is installed in water storage box 2 bottoms of urinal 1 top.Because jet water spout 5 exposes outside, and its length is enough, make an end of air inlet pipe 6 can be connected in the centre of jet water spout 5 easily, the import of the other end of air inlet pipe 6 and induced draft fan 7 is joined, the outlet of induced draft fan 7 and stack 8 join, stack 8 can directly reach outdoor, also can connect an odor removal filter 14 on stack 8.In water storage box 2, be provided with the bleed off pipe 3 that communicates with jet water spout 5,, guarantee foul smell extraction effect, be connected with an overflowing bent pipe 12 that stretches in the water, make mouth of pipe sealing at the top of bleed off pipe 3 in order not lower the exhausting negative pressure of induced draft fan.Simultaneously in flooding process, produce siphonage, have an air vent 13 on the top of overflowing bent pipe 12, communicate with atmosphere in order to prevent.Aqueous reflux is considered induced draft fan 7 and the difference in height of air inlet pipe 6 in jet water spout 5 junctions during installation in induced draft fan 7 when preventing flushing toilet bowl, the height that guarantees induced draft fan 7 to exceed bleed off pipe 3 from degree.When this formula Closet without odour uses, open induced draft fan 7, produce negative pressure in the air inlet pipe 6, foul smell after an action of the bowels can be by the water flushing channel 4 that distributes around urinal 1 upper edge, arrive induced draft fan 7 through jet water spout 5, air inlet pipe 6, discharge outdoorly by stack 8, or be cleaned, be emitted on indoor through odor removal filter 14.

Another kind of seat formula Closet without odour as shown in Figure 2, its basic structure is identical with closet shown in Figure 1, and just the distance between its water storage box 2 and the urinal 1 is very little, and jet water spout 5 is very short even be sealed in urinal 1 and water storage box 2 centres, and inconvenience connects air inlet pipe 6 thereon.Can directly link the top of the bleed off pipe 3 that communicates with jet water spout 5 this moment with air inlet pipe 6, and at inferior top connection one overflowing bent pipe 12 that stretches in the water of bleed off pipe 3.Because of air inlet pipe 6 and induced draft fan 7 lead to atmosphere, thus can siphonage not take place when overflow, after induced draft fan 7 is opened, foul smell by water flushing channel 4 through jet water spout 5, bleed off pipe 3, air inlet pipe 6 to induced draft fan 7, discharge outdoor by stack 8.

Crouching formula Closet without odour as shown in Figure 3, its basic structure are also roughly with last identical, and just its bath water source is from running water pipe 9, and hydraulic pressure is bigger.For preventing that tap water from flowing backward in the induced draft fan 7, can on air inlet pipe 6, install one and only allow air communication to cross and the float valve 11 that do not allow current to pass through.When water flowed into air inlet pipe 6, the ball float in the float valve 11 will rise and the top valve base sealing, stoped water to flow in the induced draft fan 7.And drop on the web plate of valve bottom under the ball float when anhydrous, can allow foul smell to pass through, discharge through stack 8.
