Background technology

See also TaiWan, China patent application case number No. 094204719 " being applicable to the Improvement type ventilation device of extractor fan " patent, it is a cover body, is provided with one first opening and one second opening; One baffle plate comprises several guide vanes, and this baffle plate engages with this first opening, and the air that this cover body imports/derives derives/be directed into the opposite side of this baffle plate via these several guide vanes; At least three connect workpiece, are the lower surfaces of being located at this workpiece, and this at least three connections workpiece is to be connected with an extractor fan.

Though aforementioned patent can be offered the conducting of several guide vanes as air by baffle plate, yet, its baffle plate is the passage that is directly connected in wall of no headspace, be with, its guide vane there is no and does extension in the normal direction, or the length that extends internally is easily restricted, and that the too short situation of vane plate easily causes anti-rainwater to sprinkle into effect is clear, and the opening of the external conducting of its cover body only has one, its air conducting effect only can circulate to some extent by indoor air and just be produced the water conservancy diversion effect, and its water conservancy diversion efficient of only having movement in one direction truly has improved space.

The utility model content

Go up guide vane development length deficiency in order to overcome its design of aforementioned patent, the not good shortcoming of cover body water conservancy diversion efficient, the utility model provides a kind of outdoor vent hood, it can effectively extend long flow deflector, and its guide functions not only can be by initiatively outwards circulation of room air, also can discharge, reach the design of bidirectional guide by extraneous air flow guidance inner air.

The utility model " outdoor vent hood " comprises a diversion seat portion and an outer cover body, this diversion seat portion is for the ventilating opening that is arranged at building walls, this diversion seat portion is a hollow body, this diversion seat portion is provided with the section of setting and outer peripheral edges greater than the elongated end of the section of setting, this diversion seat portion is mounted on the ventilating opening of wall by the section of setting, this is provided with Duan Yiduan and is provided with a blow vent, this blow vent conducting is in an indoor end of building, this extension is an outdoor end that exposes to building, this extension one end is a rectification face, and planning has several inwardly oblique flow deflectors on this rectification face;

This outer cover body extends the building outside by extension one end, this outer cover body is integrated in the profile of extension upper limb to both sides, and extend to the extension lower position and form a ventilating opening, and this outer cover body with respect to ventilating opening in directly over offer several pod apertures, and ventilating opening and pod apertures are the hole portion and the blow vent conductings of offering by flow deflector.

The utlity model has following characteristics:

1. the indoor air of building can be via blow vent, the hole portion that offers by flow deflector lead to pod apertures also or ventilating opening discharge.

2. this flow deflector is by space that the extension discharged, be able to the long length that internally extends to diversion seat portion, be with, even if rainwater is infiltrated in rectification face one end by pod apertures, this flow deflector also can provide fruit of preferable waterproof, avoids rainwater to infiltrate in diversion seat portion inside.

3. when room air does not initiatively circulate, also can be flowed into by ventilating opening by outdoor wind-force, the priming room air is discharged by pod apertures more in the lump via the hole portion of blow vent outflow flow deflector.

The number in the figure explanation:

1 diversion seat portion, 11 sections of setting, 111 passages

12 extensions, 121 rectification faces, 122 flow deflectors

123 hole portions, 2 outer cover bodies, 21 ventilating openings

22 pod apertures

The specific embodiment

See also Fig. 1 to shown in Figure 3, the utility model " outdoor vent hood " includes diversion seat portion 1 and outer cover body 2;

This diversion seat portion 1 is a hollow body, this diversion seat portion 1 is provided with one for the section of setting 11 that is arranged at the wall ventilating opening, reach one and expose to outdoor extension 12, the outer peripheral edges of this extension 12 are greater than the section of setting 11, this section of setting 11 1 ends are provided with a conducting in indoor blow vent 111, these extension 12 1 ends are provided with a rectification face 121, planning has several inwardly oblique flow deflectors 122 on this rectification face 121, and this flow deflector 122 is connected in rectification face 121 for the bottom, upper limb is located away from rectification face 121, tilt to be inserted into the aspect in the diversion seat portion 1 from the bottom to top, this rectification face 121 offers several hole portions 123 by flow deflector 122;
