Abstract

The present invention relates to a method for the ventilation of a toilet, particularly to a ventilation method which can make air in the toilet circulated and people had comfortable smell when the people use the toilet. The present invention has the main design ideas that the discharging direction of an air flow from the toilet is changed, particularly the discharging direction of excrement. The original air flow which flows to a ceiling from the excrement is changed to flow to an air outlet near a closet from any place in the toilet, and therefore, air in the toilet can circulate; simultaneously, abnormal smell in the toilet can be reduced to minimum through the air flow which circulates in the toilet. The present invention has the secondary aim that the aim of the present invention is ensured, and simultaneously, the present invention has the advantages of convenient construction and low cost.

Description

The method of toilet ventilation

Technical field

The present invention relates to the method for a toilet ventilation, relate in particular to a kind ofly when making the washroom circulation of air, the comfortable method of ventilation of toileting person's sense of smell of maintenance is arranged.

Background technology

According to observations, existing most lavatory, perhaps washroom, especially the design of ubiquitous public lavatory, town and country, China's Mainland, especially lack the consideration that peculiar smell is eliminated,, also exist design philosophy confusion in logic and the defective that details is not very pursued even if consider to some extent.

As: the exhaust blower that forced ventilation is used, according to observations, just often be located at the ceiling of position, perhaps directly over the toileting person.So the defective of design is, when having the air of peculiar smell from closet up, through toileting person's olfactory organ, arrive the exhaust blower that is positioned at ceiling again, discharge the washroom at last, its result well imagines, although that is: air is circulated in the washroom, but the toileting person can't avoid standing the torment of peculiar smell, makes the behavior of going to toilet become a kind of decocting of nose of holding the breath, pinch, the enjoyment and the pleasant sensation of be far from being fully light body, release.

Summary of the invention

The present invention is in view of the defective of above-mentioned existing washroom design, for avoiding it, main core design thought is: change air stream and discharge the washroom, especially discharge the just direction of position, change near from washroom in Anywhere flow to closet air outlet from just bit stream to ceiling by in the past air-flow.

In brief, main purpose of the present invention is to provide a kind of washroom air that makes to be circulated, but makes the peculiar smell in the washroom be reduced to minimum method by the air-flow that circulates simultaneously again;

Secondary objective of the present invention when being to guarantee the foregoing invention purpose, also is convenient to construction, and cost is also reduced.

For achieving the above object, the invention provides a kind of method of toilet ventilation, comprising: air outlet is located near the closet, top at exhaust air shaft, that is, axial flow blower being set with the part that the external world communicates, described axial flow blower makes just the air in the position flow from top to bottom generally.

Description of drawings

Fig. 1 is a floor map of the present invention;

Fig. 2 is a side generalized section of the present invention.

The specific embodiment

As shown in the figure, the contaminated air that the toileting person causes, because in the air outlet 1 is civil engineering air channel 3, space in the civil engineering air channel 3 communicates with exhaust air shaft 5 again, exhaust air shaft 5 tops are provided with by indoor device to outdoor pump drainage air, as axial flow blower, force toward extraneous exhausting, so in civil engineering air channel 3, caused in the exhaust air shaft 5 with respect to atmospheric negative pressure in 2 between just, therefore, air outlet 1 is near the air of toileting person, especially contaminated air, inspiration civil engineering air channel 3, and then enter exhaust air shaft 5, again through extracting out extraneous by indoor device to outdoor pump drainage air.Arrow is represented the trend of air stream among Fig. 1 and Fig. 2.

With respect to lavatory design in the past, i.e. " toileting person's ambient air comprises contaminated air; begun by excreta, through toileting person's sense of smell sense organ, arrives the air exhaust device that the toileting person top is provided with again; discharge at last ", the present invention has reduced the discomfort in toileting person's sense of smell as possible.

Except such scheme, when air outlet 1 is positioned at closet 4, especially during 5 to 50 centimetres of the back upper places of pan, best to air-polluting suction effect.

If adopt the air quantity valve in air outlet 1, especially adjustable air quantity formula air quantity valve can be regulated the suction function according to different meteorological conditions.

Wherein civil engineering air channel 3 can be designed as with respect to the horizontal quadrature direction of closet and arranges that can build the air channel wall with non-prefabricated component, also available prefabricated component is built the air channel wall.So, construction cost is minimized,, has only an axial flow blower in the present embodiment because whole exhaust system has used the device of pump drainage air minimumly, therefore the consumption to electricity has dropped to minimum, simultaneously, because do not use pipe prefabrication spare, and usefulness is the civil engineering structure, therefore, make washroom interior and exterior finishes operation,, just save a lot as the engineering of covering to pipeline.When the washroom was the public lavatory, the civil engineering air channel 3 of lateral arrangement made each 2 all air outlet 1 might be set between just.

The body of wall of closet 4 one sides or closet 4 back is built the bay wall structure 7 into hollow, and cavity links to each other with near the air outlet the closet 41 in the bay wall.

It is indoor by wall displacement that exhaust air shaft 5 is located at the washroom, is connected with civil engineering air channel 3.

On the top of exhaust air shaft 5, that is, be provided with, as axial flow blower, to force air draft by indoor device 6 to outdoor pump drainage air with the part that the external world communicates.

Civil engineering air channel 3 in the air outlet 1, bay wall and exhaust air shaft 5 mutually between space for being connected: if the housing width between two bodies of wall is designed to 8 to 30 centimetres in the bay wall, housing depth is 150 to 250 centimetres, and the effect in reality will be the best so.

The above is only in order to explain preferred embodiment of the present invention, and it is not that the present invention is done any pro forma restriction, all have following of identical creation spirit do about any modification of the present invention or change, all should be included in the category that the invention is intended to protect.

Claims
