Description:

FIELD OF INVENTION

The present invention relates to an exhaust fan, particularly, to an easily installed ceiling pipeline exhaust fan.

BACKGROUND OF THE INVENTION

The currently available ceiling pipeline exhaust fans in the market are comprised of a panel, a housing unit, a motor, a fan wheel and other components; the vulnerable components, such as motor, fan wheel, and capacitor etc., cannot be taken down separately. The ceiling pipeline exhaust fan with this type of structure not only is difficult to install, when there is a broke down (such as a bad motor or capacitor), the entire fan has to be taken apart piece by piece, burdening the maintenance work, it is costly in maintenance, and incurs unnecessary waste. In addition, there is another type of exhaust fax that integrates the vulnerable components, such as a volute, a motor, a fan wheel, and capacitors etc.; a hole is formed on a sidewall of the housing unit, and a hooking unit is installed on the volute; when installing the volute, the hooking unit is first inserted into the hole, then the volute evolves by pivoting on the hooking unit, the volute is then installed into the housing unit. Because of this evolutional installation, the housing unit is large than the volute. By the same token, for the hooking unit to be inserted into the hole, the volute needs to preserve some space for evolution; furthermore, the installation staff has to support the volute by hand when trying to have it fix in the housing unit from the other end. This type of installation requirements cause material waste when manufacturing the housing unit, transportation and package costs are also high; on the other hand, the installation is very inconvenient.

SUMMARY

Accordingly, the present invention is aimed to resolve the above described disadvantages of the current technology, an integrated structure of brand new volute and housing unit is adopted, an exhaust system with easy installation is provided.

The present invention of pipeline exhaust fan provides the technical solution: an exhaust system with easy installation includes an exhaust fan housing unit, a panel module and a motor module installed within the housing unit; the motor module at least includes a motor, a vane wheel, a volute and a motor fixed plate and inter-connected with each other; it is characterized in that there is a clip-in connecting unit provided at the inner sidewall of the housing unit; the clip-in connecting unit is used to fix the motor module after being perpendicularly inserted into the housing unit and then horizontally moved to a settled position; the clip-in connecting unit is fixed to the support plate of the motor module, the motor module is fixed to the support plate through a fastener.

The clip-in connecting unit can be bulges formed at the two corresponding sidewalls of the housing unit, and a support plate is installed at one of the sidewalls neighboring to the bulges; a location column corresponding to the bulge is provided at the motor module. A hole is provided at a sidewall that corresponds to the housing unit and support plate; a tongue piece is formed at a motor fixed plate of the motor module.

The clip-in connecting unit can also be two symmetrical check flakes formed at the same sidewall of the housing unit; a groove is formed between the two check flakes and the housing unit that is connected to the check flakes, and the groove extends along the depth of the housing unit; there is an edge board installed on the volute of the motor module, and the edge board and the volute form an integral unit.

As the improvements of the present invention, an immovable mounting strip and a movable mounting strip are symmetrically provided on the corresponding sidewalls of the housing unit, the immovable mounting strips and the housing unit are fixedly connected; a slot for adjusting the corresponding position of the housing unit is provided on the movable mounting strip along the length of the housing unit. The purpose for providing the slot is to, on top of the traditional installation of installing a bolt at the housing unit sidewall, provide an installation of mounting strips; that is, to install a balk at the ceiling first, then through the mounting aperture of the mounting strip to fix the mounting strip to the balk by a bolt, which can avoid the noise and vibration caused by installing the product directly to the ceiling, furthermore, the movable mounting strip can be adjusted to different sizes to fit between balks to ensure safe installation and to improve reliability.

For convenient installation, the present invention also improves the installation structure of the panel module; the panel module includes a panel and a garter spring underneath the panel, a mounting base is provided at a spot corresponding to the garter spring of the volute, two long grooves are symmetrically provided at the mounting base, two jaws of the garter spring are snapped into the corresponding long groove respectively. The two jaws of the garter spring are arc curvature extending outward respectively; the long groove of the mounting is higher than the end face of the housing unit after installation.

One of the advantages of the present invention is to package a motor, a motor fixed plate, a vane wheel, a capacitor, a volute into an individual motor module; the motor module is conveniently and quickly connects to the housing unit through the support plate and the clip-in connecting unit. Because the positioning method of clip-in after moving horizontally is adopted, the size of the exhaust fan housing unit is economically minimized in comparison to the evolving style installation; further, because of the substantial depth of the groove along the length of the housing unit and, after one end of the motor module is fixed in the groove, a small angle is formed between the edge board and the groove, which displaces the barycenter of the motor module, the groove carries the most weight of the motor module; or, the entire weight of the motor module can be carried by the bulges on the sidewall of the housing unit, when the motor module and the support plate are fixed together by a screw, the operator does not need to use a lot of strength to support the motor module, the motor module can be easily installed into the housing unit. Furthermore, because the top of the long groove is higher than the end face of the housing unit, the two jaws of the garter spring can be easily and accurately snapped into the long groove, it makes the installation and disassembly of the panel module real easy. During installation, because the housing unit is lighter, less effort required, the panel module and motor module can be takedown first, and install them back after fixing the housing unit onto the balk.
