Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of exhaust fan, specifically is a kind of window type exhaust fan suitable for outside open window free drilling. BACKGROUND

[0002] With the rapid development of society, more and more residents move into the building to live, and carry out various life activities in the room, such as pet, moxa, smoking, worship, etc. However, the traditional building design usually only installs active ventilation device in kitchen and bathroom and other areas, and lacks corresponding active ventilation equipment in living room, study, bedroom and other areas. In view of this situation, the market currently needs a window type exhaust fan suitable for outside open window and convenient to install. SUMMARY

[0003] The utility model aims at the above problems, provide a kind of window type exhaust fan suitable for outside open window free drilling, can improve the convenience of installation.

[0004] To achieve the above purpose, the utility model adopts the technical scheme of a kind of window type exhaust fan suitable for outside open window free drilling, it includes the frame installed in ventilation, outside open window is arranged in the outdoor side of frame, fan is installed on the frame, and telescopic shielding mechanism is arranged between the fan and frame. After outside open window is opened, ventilation opening is formed, and active ventilation is realized along with the work of fan, at this time, the space between fan and frame is shielded by telescopic shielding mechanism, to avoid return air;When it rains or does not need active ventilation, close outside open window.

[0005] Further, to facilitate the opening and closing of outside open window, the fan is located at the proximal end of the rotating connection of the outside open window.

[0006] The utility model has the beneficial effects that without drilling, adding air duct and other complex changes, when installing, user only needs to install frame on existing window directly to complete installation by oneself. Compared with traditional exhaust device needing to lay ventilation pipe or drilling on glass, the exhaust fan recorded in the utility model has significant advantages in installation convenience, and is more suitable for use after decoration or transformation.

[0011] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0012] Example 1, such as Figs. 1-3 As shown, the specific structure of this embodiment is as follows: it includes a frame 1 installed at the ventilation point. The frame 1 can be made of thermally broken aluminum alloy profiles, etc. A fan 3 is installed on the frame 1. The fan 3 is preferably installed near the rotating connection of the outward-opening window 2. A telescopic blocking mechanism 4 is provided between the fan 3 and the frame 1. The telescopic blocking mechanism 4 can be an existing mechanism such as a louver, or it can be made of a retractable or foldable material such as fabric.

[0013] Specific installation process: Based on the measured dimensions of the window frame 6 of the outward-opening window 2, the required frame 1 is processed.

[0014] Then, the fan 3 is installed on the frame 1 using bolts, clips, etc. To secure the fan 3 and prevent air leakage between the fan 3 housing and the frame 1, a vertical section 5 is provided inside the frame 1. The vertical section 5 divides the inner space of the frame into two parts, left and right, which are named the window opening area and the fan area for ease of description. The size of the fan 3 housing is adapted to the size of the fan area. The fan housing contacts the vertical section 5. The fan area is located on one side of the rotating connection between the outward-opening window 2 and its window frame 6. The fan 3 can be a long strip exhaust fan. A telescopic shielding mechanism 4 is installed in the fan area. When the telescopic shielding mechanism 4 is extended, it can close the window opening area. One end of the telescopic shielding mechanism 4 is fixed to the frame 1 or the vertical section 5. At this time, the opposite end is provided with a slot, hook, or other mechanism for temporarily fixing the telescopic shielding mechanism 4. After the fan 3 and the telescopic shielding mechanism 4 are installed, the frame is installed on the window frame 6 of the outward-opening window 2 using bolts, etc. For aesthetic purposes, a cover can be inserted into the bolt insertion point.

[0015] Specific usage instructions: After installation, open the outward-opening window 2 to create a ventilation opening. Then, extend the telescopic blocking mechanism 4 to close the window area to prevent backflow and avoid the air being exhausted and blown back, which would affect the ventilation effect. To close the outward-opening window 2, shorten the telescopic blocking mechanism 4 and then close the outward-opening window 2.

[0016] The utility model discloses make a detailed explanation to the utility model above with the embodiment, but the content only is the preferred embodiment of the utility model, can not be considered for limiting the implementation scope of the utility model. Any familiar technical person in the technical field according to the utility model technical scheme and the utility model conception of the utility model of the utility model disclosed technology range makes equivalent replacement or changes, all should cover in the protection range of the utility model.
