## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a wall fan, particularly to a hanging structure for a wall fan.
2. Description of the Prior Art
In order to use fans with convenience, save fan installing space effectively and increase circulating distance and range of air sent by fan blades, most users of fans will choose to have fans installed on a wall, thus needless to provide other spaces for placing fans. A first conventional hanging structure for a wall fan, as shown in FIG. 1, includes a hanging member 1 and a hooking member 2. The hooking member 2 is firmly locked on a wall 3, while the hanging member 1 is hung on the hooking member 2 and locked with a wall fan 4. Thus, to hang a wall fan on a wall, only have the hooking member 2 secured on the wall 3 in advance and then, have the hanging member 1 locked with the wall fan 4, and after having the hanging member 1 aligned to the hooking member 2, the hanging member 1 together with the wall fan 4 is hung on the hooking member 2, thus hanging the wall fan 4 on the wall 3. Since the hooking member 2 merely has supporting function; therefore, displacement between the hanging member 1 and the hooking member 2 may cause to happen and the wall fan 4 may fall off because of collision and earthquake.
To improve foresaid defect, a second conventional hanging structure for a wall fan was developed. The second conventional hanging structure for a wall fan, as shown in FIGS. 2 and 3, is formed with a hanging member 5 and a hooking member 6, which are the same as those described in the first preferred embodiment in use and characteristic and unnecessary to make superfluous statement. Different from the first conventional hanging structure, the second conventional hanging structure for a wall fan has two sides of the hanging member 5 respectively formed with a stop face so that when the hanging member 5 is hung on the hooking member 6, the hanging member 5 and the hooking member 6 will be impossible to carry out horizontal displacement, able to protect the wall fan 7 from falling off due to horizontal displacement of the hanging member 5. However, the hanging member 5 and the hooking member 6 can only carry out a single point of support but cannot be prevented from shifting longitudinally and thus, during shaking violently, the hanging member 5 may be disengaged from the hooking member 6 and the wall fan 7 may fall off. Therefore, the second conventional hanging structure for a wall fan still has to be ameliorated.
An improved conventional hanging structure for a wall fan, as shown in FIG. 4, includes two hanging members 8 and two hooking member 9, which are almost the same as those described in foresaid preferred embodiments in use and characteristic, except that the hanging members 8 and the hooking members 9 are increased in number and correspondingly provided on a wall and on a wall fan to have the hanging members 8 hung on the hooking members 9 to form doubt support for attaining effect of stability, thus improving foresaid risk that the hanging structure may be turned over and fall off when swaying violently. However, this improved hanging structure for a wall fan still cannot restrict the hanging members 8 and the hooking members 9 to shift longitudinally and further, before the hanging members 8 and the hooking members 9 are locked together, each other's spacing distance and position height must be accurately measured in advance; otherwise the hanging members 8 may be impossible to be hung on the hooking members 9; therefore, this hanging structure for a wall fan still has to be further improved.
Having observed foresaid defects of the conventional hanging structure for a wall fan, the inventor of this invention adheres to the spirit of constantly striving for perfection and concentrates on study and research for improving the hanging structure for a wall fan and hence devises this invention.
SUMMARY OF THE INVENTION
The objective of this invention is to offer a hanging structure for a wall fan, easy to be assembled with a wall fan and installed on a wall, able to simplify aligning, positioning and locking operation and enabling a wall fan to be firmly hung on a wall to avoid displacement for protection of the wall fan.
The hanging structure for a wall fan, able to have a wall fan firmly hung on a wall, includes a fixing unit provided with a board to be locked on a wall. The board is formed with at least one first hanging member and a least one first locking member, the first hanging member being longitudinally fixed on the board. A hanging unit contains a casing, which is fixed with the wall fan and serves as a power source control box. The casing is provided therein with at least one second hanging member by which the casing can be hung on the first hanging member of the board. The casing is further disposed with at least one second locking member corresponding to the first locking member of the board to enable the casing to be secured with the board from the outside via the first and the second locking members, with the casing roughly covering the board.
The hanging structure for a wall fan of this invention is easy to have the second hanging member of the casing and the first hanging member of the board aligned to each other, fixed in position and hung together, and by having the first locking member of the board and the second locking member of the casing locked together, the wall fan can be firmly hung on the wall and avoid displacement, attaining effect of protection of the wall fan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A first preferred embodiment of a hanging structure 100 for a wall fan in the present invention, as shown in FIGS. 5 and 6, includes a fixing unit 10 and a hanging unit 20 as main components combined together.
The fixing unit 10 consists of a board 11 to be locked on a wall. The board 11 is provided thereon with two first hanging members 12 and two first locking members 13, and the two first locking members 13 are longitudinally fixed on the board 11 and respectively bored with a threaded hole 14, which is spaced apart from the board 11. The two first hanging members 12 are respectively a hook, formed integrally with the board 11 and fixed longitudinally on the board 11.
The hanging unit 20 contains a casing 21 fixed on the wall fan and serving as a power source control box. The casing 21 is provided therein with a second hanging member 22, which is a cross bar spaced apart from the casing 21 and by which the casing 21 can be hung on the first hanging members 12 of the board 11. Further, the casing 21 is formed with two second locking members 23 respectively corresponding to the first locking members 13 of the board 11, and the second locking members 23 are respectively a locking hole 24 corresponding with the threaded hole 14 of the first locking member 13 so that screws can be inserted through the locking holes 24 and screwed with the threaded hole 14 from the outside to lock the casing 21 on the board 11, letting the casing 21 roughly cover the board 11. The casing 21 is further formed with an opening 25 for power source wires of the wall fan to be inserted therethrough for facilitating connection of a power source.
Referring to FIGS. 7 and 8, the hanging structure 100 for a wall fan in the present invention, able to hang a wall fan 200 on a wall, further includes a connecting rod 21 and a wall fan control member 40.
The connecting rod 30 has one end connected with the casing 21 and another end connected with the wall fan 200.
The wall fan control member 40 is received in the casing 21 and extended out of the casing 21 and electrically connected with the wall fan 200 for controlling rotation speed and intensity of the wall fan 200.
Referring to FIGS. 6, 7 and 8, to make use of the hanging structure 100 for hanging the wall fan 200 on a wall, firstly, have the board 11 of the fixing unit 10 firmly locked on a wall 300 and then, make the second hanging member 22 of the casing 21 aligned to the first hanging members 12 of the board 11 and thus the casing 21 can easily be positioned and hung on the board 11. Lastly, screws are inserted through the second locking members 23 (locking holes 24) and screwed in the threaded holes 14 of the first locking members 13 to assemble the casing 21 on the board 11 and have the wall fan 200 hung on the wall 300 via the hanging structure 100.
Referring to FIGS. 6-8, since the first hanging members 12 are formed integrally with the board 11 and made in a metal processing way of punching press; therefore, the first hanging members 12 has good supporting and hanging functions. Moreover, by having the second hanging member 22 of the casing 21 hung on the first hanging members 12 of the board 11, aligning and positioning operation between the threaded holes 14 of the board 11 and the second locking members 23 (locking holes 24) of the casing 21 can be completed at the same time, able to simplify locking operation out of the casing 21. Thus, by having the board 11 and the casing 21 of the hanging structure 100 assembled together, the risk that positioning and locking operation of the conventional hanging structure always results in failure because of wrong measure in space and distance can be eliminated. The hanging structure for a wall fan of this invention is impossible to carry out horizontal and longitudinal displacement and hence can be firmly hung on a wall, able to attain effect of protection and improve the shortcomings that the conventional hanging structure can only be prevented from shifting horizontally but cannot avoid carrying out longitudinal displacement. Further, the casing 21 can roughly cover the board 11, able to increase visual beauty.
A second preferred embodiment of a hanging structure 100 for a wall fan in the present invention, as shown in FIGS. 9, 10 and 11, has the board 11 of the fixing unit 10 provided thereon with four first hanging members 12 and a first locking member 13, and the casing 21 of the hanging unit 20 provided with four second hanging members 22 and a second locking member 23 (locking hole 24). The first hanging members 12 are respectively a hook, and the second hanging members 22 are respectively an insert hole and thus, the casing 21 can be hung on the first hanging members 12 of the board 11 via the second hanging members 22. The first locking member 13 of the fixing unit 10 is extended out of the casing 21 to make the threaded hole 14 of the first locking member 13 and the second locking member 23 (locking hole 24) of the casing 21 aligned to each other so that a screw can be inserted in both the threaded hole 14 and the second locking member 23 (locking hole 24) from the outside for firmly locking the casing 21 on the board 11.
Referring to FIGS. 11 and 12, compared with the first preferred embodiment, the second preferred embodiment that is provided with the four second hanging members 12 is easy to attain aligning and positioning effects and has good supporting function and further can evenly distribute hanging load of the first hanging members 12, able to support the hanging structure more stably. In addition, the first locking member 13 of the fixing unit 10 is extended out of the casing 21 to let the threaded hole 14 of the first locking member 13 and the second locking member 23 (locking hole 24) of the casing 21 corresponding with each other, not only facilitating carrying out aligning and locking operation from the outside, but also stabilizing the hanging structure after the hanging structure is locked. And by so designing, the hanging structure 100 and the wall fan 200 are impossible to carry out horizontal and longitudinal displacement, thus achieving effect of protection.
To sun up, the hanging structure for a wall fan of this invention is easy to have the second hanging members of the casing and the first hanging members of the board aligned mutually, fixed in position and hung together, and the first locking member of the board and the second locking member of the casing can conveniently be locked together to complete hanging a wall fan on a wall. Thus, the wall fan can be firmly hung on a wall to avoid displacement, able to attain effect of protection and simplify aligning, positioning and locking operation.
