Description
Technical Field
The utility model belongs to the technical field of smoke exhaust and exhaust, in particular to a device for collecting and discharging rainwater in a hood; the utility model discloses provide a hood simultaneously.
Background
At present, the blast caps installed at the air outlets of the house exhaust passage system on the roof can be divided into three categories: the first type of hood is provided with a flat plate-shaped or umbrella-shaped top cover plate right above the air outlet, and the flue gas is discharged from the lower part of the top cover plate to the periphery. The disadvantages of this type of hood are: the structure is too simple, and when encountering the cross rain of oblique wind, the wind and rain can flow backward into the exhaust passage easily, thereby not only preventing the smoke in the exhaust passage from being discharged normally, but also enabling the rainwater to flow into the indoor space along the exhaust passage. The second type hood is an improvement on the first type hood, and is characterized in that a rainproof shutter is arranged at an exhaust port below a top cover plate, so that the rainproof performance of the hood is improved to a certain degree, but the effective ventilation area of the exhaust port is obviously reduced, the air speed at the exhaust port is reduced, the exhaust wind resistance of the hood is obviously increased, and unsmooth exhaust is caused. To solve this problem, it is necessary to significantly increase the size of the louver, resulting in a waste of building space and an unattractive appearance. The third type of hood is also an improvement on the first type of hood, a circle of wind shielding side plate is arranged on the outer side of the exhaust port below the flat plate cover plate or the umbrella-shaped cover plate, and smoke is discharged outwards from a gap between the cover plate and the side plate. If the clearance between the wind shielding side plate of the hood and the cover plate is too small, the exhaust wind resistance is large, and the difficulty in smoke exhaust is caused; if the clearance between the wind shielding side plate and the cover plate of the wind cap is too large, the wind and the rain can flow backwards into the exhaust passage inevitably in the weather of oblique wind and transverse rain.
In order to overcome the defects, the applicant proposes an improvement (application number is 201911291499.5), an inner air duct extends upwards along the upper end surface of the flow guide body to form a side wall capable of receiving rebound air or rainwater generated after falling to the inner wall of the outer air duct, and a drainage section which is communicated with the upper part and the lower part and exhausts air is formed between the side wall and the inner wall of the outer air duct; the mode can effectively solve the phenomenon of wind or rainwater rebounding, but during heavy rainfall, a large amount of rainwater enters the hood to form a rain curtain to block the process of outward emission of smoke, and rainwater and smoke directly collide to cause water splash to splash in the process, so that a small amount of rainwater rebounds to enter the exhaust passage.
