Description
Technical field
The utility model is related to a kind of public lavatory post unpowered exhaust system of formula, belongs to architectural design field.
Background technology
At present office building, hotel, premises public lavatory（Toilet）It is long-standing one old that stink is unpleasant
Problem, the conventional method for using now is that, by outer wall window ventilation, do not have the lavatory of window（Toilet）By the reserved row of building
Stomata is divulged information.More advanced has using electrically ventilating machine, this draft type is taken a breath in the presence of start, noise is big, power consumption is big,
It is the problems such as labor management is costly, relatively costly, be not suitable for the energy-conserving and environment-protective theory of modern promotion.
Utility model content
The purpose of this utility model is：For the problem that above-mentioned prior art is present, propose a kind of structural principle it is simple,
The public lavatory post unpowered exhaust system of formula that low cost, exhaust effect are good, energy consumption is low.
In order to reach object above, a kind of public lavatory post unpowered exhaust system of formula that the utility model is related to, bag
Include the vertical exhaust duct for being arranged on the outdoor unpowered blast cap in floor top and being attached thereto installation；It is characterized in that：Also include
It is disposed in the interior the horizontal exhaust duct connected with vertical exhaust duct；The horizontal exhaust duct is small away from vertical air draft tube end diameter
In the reducer pipe of connection end diameter；One group of low level exhaust outlet corresponding with crouching formula lavatory position position, institute are set on the reducer pipe
State and blast pipe branch pipe is installed on low level exhaust outlet.
The utility model further the technical scheme that limits as：Ventilating fan and unidirectional is installed in the end of the reducer pipe
Air door.
Further, the unidirectional air door is to be hinged on the deep bead at the top of the reducing tube wall of ventilating fan inner side；It is described to keep out the wind
Limited block is provided with reducing tube wall immediately below plate.
Further, the blast pipe branch pipe is L-shaped structure, and its horizontal ends is arranged on horizontal row parallel to horizontal exhaust duct
In airduct；Its vertical end is arranged on lavatory position back upper place.
Further, the blast pipe branch pipe is horn-like structure near the port of lavatory position position.
The beneficial effects of the utility model：Formula unpowered exhaust system in post of the present utility model is one kind several lavatories
Low level exhaust outlet, horizontal exhaust duct, vertical exhaust duct that position is set by each lavatory position（Well）And unpowered blast cap composition into
A kind of exhaust system of group arrangement, the Natural Ventilation Principle formed using blast and hot pressing, using upper air inlet, the row of sending of lower return air
Wind mode organizes the air-flow in public lavatory, using vertical exhaust duct（Well）Stack effect and unpowered blast cap strengthen from bottom to top
Vertical air flow, exhaust system is pumped into by the dirty gas below the position of lavatory, and in air discharge high, is reached and led in raising public lavatory
Wind ventilation effect.The utility model exhaust system does not need driven by power, can for a long time operate and noise is relatively low, and exhaust duct is used
The common stainless steel being easy to get or PVC anticorrosives make, simple structure, it is easy to install and make, cheap, energy-saving and emission-reduction.
Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the local scheme of installation of the horizontal exhaust duct of the utility model and blast pipe branch pipe.
Specific embodiment
Embodiment one
A kind of public lavatory post unpowered exhaust system of formula of the present embodiment, basic structure is as shown in Figure 1-2：Including setting
Put outdoor unpowered blast cap 1 at the top of floor and be attached thereto the vertical exhaust duct 2 of installation；Also include being disposed in the interior and erecting
To the horizontal exhaust duct 3 that exhaust duct 2 is connected；Horizontal exhaust duct 3 is to be less than connection end diameter away from vertical air draft tube end diameter
Reducer pipe；One group of low level exhaust outlet corresponding with crouching formula lavatory position position, the row of being provided with low level exhaust outlet are set on reducer pipe
Tracheae branch pipe 4.Ventilating fan 5 and unidirectional air door are installed in the end of reducer pipe.
Due to horizontal exhaust duct 3 from vertical exhaust duct 2 more away from end, blast is smaller；So horizontal exhaust duct 3 is set to
The reducer pipe of head wide and tail narrow, enhances the blast in the end of horizontal exhaust duct 3, that is, strengthen remote lavatory position blast, and then increased whole
Individual system exhaust ventilation effect.
Unidirectional air door is that the deep bead 7 at the top of the inner side reducing tube wall of ventilating fan 5 is hinged on by hinge 9；Deep bead 7 just under
Limited block 8 is provided with the reducing tube wall of side.Exhaust fan effect is standby, and exhaust fan is opened as needed.Indoors stink compared with
Standby ventilating fan is opened when greatly, distributing slower, air draft is carried out because the effect of ventilating fan wind-force blows deep bead 7 open, work as nothing
Power blast cap works independently when meeting air draft needs, and deep bead 7 is blown to bottom and is limited by limited block 8 by the blast in horizontal exhaust duct
Position sealing, so as to ensure that the blast in horizontal exhaust duct.
One end port of blast pipe branch pipe 4 is plugged in horizontal exhaust duct towards vertical exhaust duct level, and the other end is located at
The back upper place of lavatory position, in inverted L-shaped attachment structure.Blast pipe branch pipe 4 is horn-like collection port 6 near the port of lavatory position position.Lavatory
The effect that position one end of air exhaust branch pipe 4 is plugged in horizontal exhaust duct is smoothly, by the gas collection discharge of this lavatory position, to prevent reverse biography
To face lavatory position.The effect of horn-like collection port 6 improves gas collection efficiency.
In addition to the implementation, the utility model can also have other embodiment.All use equivalents or equivalent change
The technical scheme to be formed is changed, the protection domain of the utility model requirement is all fallen within.
