Abstract
Toilet ventilation system of the present utility model, comprises ventilation stack and the gravity vent being communicated with every floor washroom and ventilation stack, also comprises the back-flow preventer be arranged on each gravity vent and the induced draft fan being arranged at ventilation stack outlet; Described back-flow preventer comprises inclination mozzle and vertical mozzle, and inclination mozzle is fixed on gravity vent through wall, and vertical mozzle is fixed on the upper end of inclination mozzle.Toilet ventilation system of the present utility model, is provided with back-flow preventer, effectively can prevent floor gap smell crossfire; And in ventilation stack exit, induced draft fan is set to extract the gas in ventilation stack, improve exhaust effect.
Description
Technical field
The utility model relates to a kind of toilet ventilation system, belongs to building construction support device technical field.
Background technology
At present, the gravity vent of washroom in traditional building, is generally above wall, open a gravity vent be connected with interior wall ventilation stack, is discharged by the smell of indoor via gravity vent in ventilation stack.But, when the smell that lower floor's building is discharged upwards discharges in ventilation stack, when running into the gravity vent on wall, will, to pore diffusion, make the room air of upper strata building suffer odor contamination.In order to prevent peculiar smell, generally in each washroom, exhaust fan is installed, or on each toilet, exhaust plant is installed, but these measure exhaust effects are general, and the words of exhaust plant installed by each washroom or toilet, bothering very much, when having exhaust fan or other exhaust plant damage, must keep in repair in turn.
Utility model content
The utility model, in order to overcome the deficiency of above technology, provides a kind of toilet ventilation system, prevents floor gap smell crossfire, improves exhaust effect.
the utility model overcomes the technical scheme that its technical problem adopts:
A kind of toilet ventilation system, comprises ventilation stack and the gravity vent being communicated with every floor washroom and ventilation stack, also comprises the back-flow preventer be arranged on each gravity vent and the induced draft fan being arranged at ventilation stack outlet; Described back-flow preventer comprises inclination mozzle and vertical mozzle, and inclination mozzle is fixed on gravity vent through wall, and vertical mozzle is fixed on the upper end of inclination mozzle.
Preferred according to the utility model, the angle of described inclination mozzle and vertical direction is 20-80 °.
Preferred according to the utility model, the length of described vertical mozzle is 10-40cm.
Preferred according to the utility model, described induced draft fan is negative pressure induced draft fan.
Preferred according to the utility model, be provided with fan shroud above described induced draft fan.
the beneficial effects of the utility model are:
Toilet ventilation system of the present utility model, is provided with back-flow preventer, effectively can prevent floor gap smell crossfire; And in ventilation stack exit, induced draft fan is set to extract the gas in ventilation stack, improve exhaust effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, ventilation stack, 2, gravity vent, 3, back-flow preventer, 31, inclination mozzle, 32, vertically mozzle, 4, induced draft fan, 5, fan shroud.
Detailed description of the invention
Better understand the utility model for the ease of those skilled in the art, be described in further details below in conjunction with the drawings and specific embodiments to the utility model, following is only exemplary do not limit protection domain of the present utility model.
As shown in Figure 1; toilet ventilation system of the present utility model; comprise ventilation stack 1 and the gravity vent 2 being communicated with every floor washroom and ventilation stack; described each gravity vent is provided with back-flow preventer 3; the roof in ventilation stack exit is provided with negative pressure induced draft fan 4, negative-pressure air fan exhausting usefulness is good, and a general ventilation stack selects a negative pressure induced draft fan; the top of negative pressure induced draft fan 4 is provided with fan shroud 5, avoids by extraneous adverse weather conditions in order to protect blower fan.Described back-flow preventer 3 comprises inclination mozzle 31 and vertical mozzle 32, and inclination mozzle 31 is fixed on gravity vent 2 through wall, and vertical mozzle 32 is fixed on the upper end of inclination mozzle 31; The utility model medium dip mozzle 31 is 20-80 ° with the angle of vertical direction, more preferably 60 °; The length of vertical mozzle 32 is 10-40cm, further preferred 20cm.
The gas of every floor washroom enters in ventilation stack 1 through the back-flow preventer 3 of each floor, when having gas flow in ventilation stack 1 when the gravity vent 2 of upper strata building, the vertical mozzle 32 of back-flow preventer 3 stops smell horizontal proliferation, add the draft effect of ventilation stack 1 exit negative pressure induced draft fan 4, make upper strata building can not suffer the smell crossfire of lower floor's building, also improve exhaust effect.
Above only describes general principle of the present utility model and preferred embodiment, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection domain of the present utility model.
