Controllable ventilation domatic roof
Technical field
The utility model relates to field of house buildings, particularly relates to a kind of controllable ventilation domatic roof.
Background technology
There is a kind of design of roof at present, the basis on original flat roof arranges the inclined roof that does not live people, inside, domatic roof is cavity structure, the advantage of this design is the solar irradiation decreasing former roof summer, improve the surface temperature on former roof winter, totally reduce the energy consumption of its top-floor house, improve its comfort level.If but summer temp is too high, because air in cavity cannot circulate, the heat of cavity inside will by bulk deposition, even can exceed outdoor temperature, once the temperature of indoor is lower than the temperature in cavity, the heat in cavity will, to indoor transmission, make indoor temperature raise further.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, cost is low, it is ingenious to design, the controllable ventilation domatic roof of good cooling effect.
The utility model controllable ventilation domatic roof, comprise domatic roof, inside, domatic roof is provided with cavity, wherein: comprise discharge duct and inlet channel, bottom, domatic roof is provided with admission line, the new wind outlet of admission line one end and the cavity connects of inside, domatic roof, the fresh inlet of the other end is communicated with the space outerpace of bottom, domatic roof, the top on domatic roof is provided with discharge duct, the upper end open of discharge duct and the cavity connects of inside, domatic roof, the lower ending opening of discharge duct is communicated with the space outerpace on top, domatic roof.
The utility model controllable ventilation domatic roof, wherein said controllable ventilation domatic roof also comprises rain cover, and rain cover is arranged on above the upper end open of discharge duct.
The utility model controllable ventilation domatic roof, the pipeline at wherein said fresh inlet place is provided with the first stop valve.
The utility model controllable ventilation domatic roof, the quantity of wherein said admission line is at least one, and all admission lines are all evenly arranged along the edge of bottom, domatic roof.
The utility model controllable ventilation domatic roof, wherein said discharge duct is vertically arranged on the top on domatic roof.
The utility model controllable ventilation domatic roof, the lower ending opening place of wherein said discharge duct is provided with the second stop valve.
The utility model controllable ventilation domatic roof difference from prior art is: the utility model structure is simple, cost is low, be skillfully constructed, good to the cooling-down effect of indoor.Admission line and discharge duct is respectively arranged with in bottom, domatic roof and top, admission line is provided with the first stop valve, discharge duct is provided with the second stop valve, under the effect of the temperature difference, fresh air enters the cavity of inside, domatic roof from admission line, original air in cavity is discharged by discharge duct, ensure that the air in cavity is in circulation status, greatly reduce the temperature of the air in cavity, thus reduce indoor temperature.The quantity that can also opened by adjustable cut-off valve or close, is changed the speed that cavity air flow is logical, thus makes indoor reach the object of cooling in summer Winter protection.
Below in conjunction with accompanying drawing, the utility model controllable ventilation domatic roof is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation on the utility model controllable ventilation domatic roof.
Detailed description of the invention
As shown in Figure 1, be the structural representation on the utility model controllable ventilation domatic roof, comprise domatic roof 1, discharge duct 4, rain cover 5 and many inlet channels 3.Inside, domatic roof 1 is provided with cavity 2, edge along bottom, domatic roof 1 is evenly provided with many admission lines 3, the new wind outlet of admission line 3 one end is communicated with the cavity 2 of inside, domatic roof 1, the fresh inlet of the other end is communicated with the space outerpace of bottom, domatic roof 1, and the pipeline at each fresh inlet place is separately installed with the first stop valve.Discharge duct 4 is vertically provided with on the top along domatic roof 1, the lower ending opening of discharge duct 4 is communicated with the cavity 2 of inside, domatic roof 1, the upper end open of discharge duct 4 is communicated with the space outerpace on top, domatic roof 1, is provided with the second stop valve at the lower ending opening place of discharge duct 4.On discharge duct 4 upper end open, rain cover 5 is installed, prevents rainwater, dust or some impurity from entering into the cavity 2 of inside, domatic roof 1 by discharge duct 4.
Operation principle of the present utility model is: in summer, when too high temperature of air in the cavity 2 of inside, domatic roof 1, open the first stop valve on fresh inlet place pipeline, open the second stop valve on discharge duct 4, fresh air extraneous under the effect of internal-external temperature difference is pumped in the cavity 2 of inside, domatic roof 1 by admission line 3 simultaneously.Because in the cavity 2 of inside, domatic roof 1, original air themperature is higher, when fresh air enters cavity 2 inside from bottom, domatic roof 1, original high temperature air moves upward, finally discharge from the discharge duct 4 on top, domatic roof 1, the gas in domatic roof 1 internal cavities 2 is made constantly to circulate by this way, greatly reduce the temperature of cavity 2 inside, thus indoor temperature is declined.If the air passage rates of cavity 2 inside is excessively slow, multiple first stop valve can be opened simultaneously, increase the velocity of liquid assets of cavity 2 inner air.In the winter time, when not needing to reduce indoor temperature, close the first stop valve on fresh inlet place pipeline and the second stop valve on discharge duct 4 simultaneously, the gas in domatic roof 1 internal cavities 2 is not circulated, makes indoor reach the object of insulation.
The utility model controllable ventilation domatic roof, admission line 3 and discharge duct 4 is respectively arranged with in bottom, domatic roof 1 and top, admission line 3 is provided with the first stop valve, discharge duct 4 is provided with the second stop valve, under the effect of the temperature difference, make fresh air enter the cavity 2 of inside, domatic roof 1 from admission line 3, original air in cavity 2 is discharged by discharge duct 4, ensure that the air in cavity 2 is in circulation status, greatly reduce the temperature of the air in cavity 2, thus reduce indoor temperature.The quantity that can also opened by adjustment first stop valve or be closed, changes the speed that cavity 2 air flow is logical, thus makes indoor reach livable temperature.The utility model structure is simple, cost is low, be skillfully constructed, good to the cooling-down effect of indoor, compared with prior art there is obvious advantage.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
