Description

Technical Field

[0001] The utility model relates to the technical field of building roof structures, in particular to a natural ventilator for a house. Background Art

[0002] Air towers, also known as ventilation skylights, are generally used for ventilation of rooftops of light steel and heavy steel plants. Ventilation is a building environment control technology that uses ventilation dilution or ventilation removal to control the spread and harm of air pollutants, thereby ensuring the quality of indoor and outdoor air environments.

[0003] However, existing widely used ventilation products, such as unpowered rotating hoods, have the following problems: unpowered rotating hoods are easily damaged, have large wind resistance and need to be replaced frequently, resulting in waste; unpowered hoods have slow heat dissipation and exhaust effects; unpowered rotating hoods not only fail to exhaust gas in windy weather, but also cause wind backflow into the house; unpowered rotating hoods are prone to roof leaks after installation; poor lighting and the air outlet being connected to the outside world can easily cause foreign objects to enter the house through the air outlet. Utility Model Content

The side panels are fixed along the groove direction of the roof tiles, the right-angle baffle is located between the first frame and the second frame, and the two ends of the right-angle baffle are respectively fixedly connected to the inner sides of the side panels on both sides, the right-angle baffle is L-shaped, the upper end of the right-angle baffle is connected to the upper end of the second frame, and the lower end of the right-angle baffle faces one side of the first frame, so that the exhaust in the house forms an L-shaped air outlet route along the right-angle baffle. By adopting the chimney effect, based on the thermal pressure effect, that is, due to the temperature difference between the air inside and outside the chimney, the temperature difference makes the air density inside and outside different (high temperature air has a small density, and low temperature air has a large density), and finally drives the directional flow of air inside and outside the chimney. When the stove or boiler is in operation, the hot air generated rises along the chimney and leaves at the top of the chimney.

[0006] Preferably, an isolation breathable net is provided on the upper end of the right-angle baffle, and both ends of the isolation breathable net are respectively connected to the upper end of the first frame and the upper end of the second frame, so that debris is blocked from the air outlet through the isolation breathable net.

[0007] Preferably, a notch is provided on each of the two lateral sides of the right-angle baffle on the side plates, and a wind-blocking baffle is provided outside the notch to block cross wind from entering the ventilator.

[0008] Preferably, a drainage outlet is provided between the lower end of the wind blocking baffle and the right-angle baffle, and rainwater falling into the right-angle baffle is discharged laterally through the drainage outlet.

[0009] Preferably, the lower end of the right-angle baffle is close to the first frame, and the lower end of the right-angle baffle is parallel to the isolation and breathable net above.

[0010] Preferably, the lower end of the right-angle baffle exceeds the roof end surface at the air outlet, and rainwater passes through the isolation and breathable net and falls to the lateral part of the right-angle baffle, flows to the roof surface below the air outlet, and flows down along the roof tile grooves.

[0011] Preferably, both ends of the ridge tile are respectively located above the lower end of the second frame, thereby preventing rainwater from leaking into the air outlet, and the rainwater falling on the ridge tile flows out laterally.

[0012] Preferably, the first frame and the second frame are arranged on the roof surface in an inverted cone shape, guiding the wind trajectory along the first frame and the second frame to flow toward the central isolation breathable net, and through the Bernoulli effect, the greater the outdoor wind force, the faster the exhaust speed is achieved.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model is more economical, environmentally friendly, efficient and convenient to solve the problems of roof heat dissipation failure and poor indoor air circulation faced by many houses, without any machinery and equipment or external power equipment. Compared with the existing widely used ventilation products, the utility model specifically includes the following advantages:

[0014] 1) The design has low wind resistance, one-time installation and lifelong maintenance-free, energy-saving and environmentally friendly, which solves the problem of waste caused by the unpowered rotating hood being easily damaged and the large wind resistance requiring frequent replacement;

[0015] 2) The chimney effect can solve the problem of roof heat dissipation and indoor air circulation more quickly. Its heat dissipation and exhaust capacity is more than 5 times that of the unpowered hood, solving the problem of slow heat dissipation and exhaust effect of the unpowered hood;

[0016] 3) Using the Bernoulli principle effect, the greater the outdoor wind force, the faster the exhaust speed. Its structural design prevents the wind from flowing back into the factory through the air outlet. This product solves the problem that the unpowered hood not only cannot exhaust gas in windy weather, but also causes the wind to flow back into the house;

[0017] 4) Easy installation, perfect rainproof design, solves the problem of roof leakage after the installation of the unpowered hood;

[0018] 5) The first frame can be made of stainless steel, and the middle area can be made of transparent lighting materials to increase indoor lighting in the house, solving the problem that existing ventilation and exhaust products cannot provide lighting;

[0019] 6) An isolation and breathable net made of mesh material is set above the air outlet to cover it, which solves the problem of foreign objects such as birds and garbage entering the house through the air outlet of the unpowered hood. BRIEF DESCRIPTION OF THE DRAWINGS

The ventilator is correspondingly arranged above the air outlet 1. The ventilator includes a first frame 3, a second frame 4, a right-angle baffle 5 and a side panel 8. The first frame 3 and the second frame 4 can be made of durable materials, such as stainless steel, fiberglass and the like, and the middle area can be replaced with transparent lighting materials, such as tempered glass, transparent tiles, etc. according to needs; the first frame 3 is located at the lower end of the air outlet 1, the second frame 4 is located at the upper end of the air outlet 1, and the side panel 8 The first frame 3 and the second frame 4 are respectively located on both sides to fix the two, and the lower end of the first frame 3 is fixed to the surface of the roof tile 6 on the roof surface, and the lower end of the second frame 4 is fixed to both sides of the ridge tile 2 in the middle of the roof. At the same time, the lower end position of the second frame 4 can be adjusted according to the position of the air outlet, and is sealed and connected to the roof surface through a sealing strip to prevent rainwater from leaking into the air outlet along the lower end of the second frame; the lower end of the side panel 8 is fixed along the groove direction of the roof tile, and the right-angle baffle 5 is located between the first frame 3 and the second frame 4, and the two ends of the right-angle baffle 5 They are respectively fixedly connected to the inner sides of the side panels 8 on both sides, the right-angle baffle 5 is L-shaped, the upper end of the right-angle baffle 5 is connected to the upper end of the second frame 4, the lower end of the right-angle baffle 5 is close to the side of the first frame 3, and the lower end of the right-angle baffle 5 is parallel to the isolation and ventilation net 7 above, and the exhaust in the house forms an L-shaped air outlet route along the right-angle baffle 5, and the right-angle baffle 5 is provided with a notch on the side panels 8 on both sides of the horizontal direction, and a wind-blocking baffle 9 is provided on the outside of the notch to prevent cross wind from entering the ventilator, and a drain outlet 10 is provided between the lower end of the wind-blocking baffle 9 and the right-angle baffle 5. The rainwater falling into the right-angle baffle 5 is discharged laterally through the drain port 10. The first frame 3 and the second frame 4 are arranged on the roof surface in an inverted cone shape, guiding the wind trajectory along the first frame 3 and the second frame 4 to flow toward the central isolation breathable net 7, and through the Bernoulli effect, the greater the outdoor wind force, the faster the exhaust speed is achieved. By adopting the chimney effect, based on the thermal pressure effect, that is, due to the temperature difference between the air inside and outside the chimney, the temperature difference makes the air density inside and outside different (high temperature air has a small density, and low temperature air has a large density), which ultimately drives the directional flow of air inside and outside the chimney.When the stove or boiler is in operation, the hot air generated rises along the chimney and leaves at the top of the chimney.

The air outlet 1 is closed by the isolating and breathable net 7, that is, the air outlet 1 is blocked by the isolating and breathable net 7, thereby solving the problem of foreign objects such as birds and garbage entering the house through the air outlet of the unpowered rotating hood. The lower end of the right-angle baffle 5 exceeds the roof end surface at the air outlet 1, and rainwater falls through the isolating and breathable net 7 to the lateral part of the right-angle baffle 5, and flows to the roof surface below the air outlet 1, and flows down along the grooves of the roof tiles 6. The two ends of the ridge tiles 2 are respectively pressed on the lower end of the second frame 4, thereby preventing rainwater from leaking into the air outlet 1, and the rainwater falling on the ridge tiles 2 flows out laterally.

[0032] The specific working principle is that the hot air in the house passes through the chimney effect, such as Figure 5 As shown, the air efficiently rises from the air outlet 1 at the top of the roof, flows along the L-shaped right-angle baffle 5, and is finally discharged from the isolation air-permeable net 7. The utility model also combines the Bernoulli effect, such as Figure 6 As shown in the figure, the stronger the outdoor wind is, the faster the indoor hot air will be exhausted. At the same time, when it rains, Figure 7 As shown, rainwater falls from the isolation breathable net 7 to the inside of the first frame 3 and the second frame 4, and falls to the lateral part of the L-shaped right-angle baffle 5, and flows toward the lower end along the right-angle baffle 5, and finally falls into the tile groove of the roof tile 6 at the lower end, and naturally flows downward, and the rainwater falling between the second frame 4 will fall to the surface of the ridge tile 2, and the rainwater here will naturally flow out horizontally.

[0033] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
