Description
- (1) Fields of the Invention
- The present invention relates to a fan, and more particularly, to an air circulation fan to quickly circulate air in a room, and the air is filtered by the filtering members of the fan.
- (2) Descriptions of Related Art
- Generally, when using an air conditioner to cool down the air temperature in a room, it takes about 15 to 20 minutes for the operation of the compressor of the air conditioner to let the air temperature to drop to the desired value. However, this action consumes a lot of electric energy, so that people uses a ceiling fan to accelerate the air circulation to reduce the time required.
- The conventional ceiling fan generally comprises a motor which drives the fans to blow the air in the upper portion of the room downward. However, the hot air usually is located in the upper portion of the room so that the conventional ceiling fan blows the hot air downward, while the cold air is still located in the lower portion of the room, so that the air circulation is not efficient. The purpose of reducing the air temperature in the room mentioned above cannot achieve quickly, and the electric energy cannot be saved as expected. Besides, the downward blowing of the air can blow the dust on the floor and which is not good for the people in the room.
- The present invention intends to provide an improved ceiling fan that improves the shortcomings mentioned above.
- The present invention relates to an air circulation fan and comprises a rod having a fixing portion fixed to a ceiling. A motor is connected to the lower end of the rod. A fan has a base, an annular cover and multiple upright blades. The base is connected to the motor and driven by the motor. The cover is horizontally connected to the underside of the base so as to form a space between the base and the cover. The blades are connected between the base and the cover. The blades are arranged along the periphery of the fan. Multiple outlets are defined between the blades and communicate with the space. An inlet is defined through the underside of the fan and communicates with the space. Multiple filtering members are connected between the base and the cover and located on the periphery of the fan to cover up the outlets. Air is sucked from the inlet and circulates by the rotation of the blades, and passes through the filtering members and flows out from the outlets.
- The primary object of the present invention is to provide an air circulation fan wherein the rotation of the blades of the fan sucks air from the inlet and generates spiral air flows which flow out from the outlets via the filtering members. The cool air in the lower portion of the room is sucked upward and circulates with the hot air in the upper portion of the room so that the temperature of the room can be quickly reduced by the mixture of the hot and cool air. The filtering members filter the air to increase the quality of the air in the room.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

FIG. 4 is another angle to show that the filtering members are to be connected to the air circulation fan of the present invention; -
FIG. 5 is a perspective view, viewed from the underside of the air circulation fan of the present invention, and -
FIG. 6 is a cross sectional view to show the air flows through the air circulation fan of the present invention. - Referring to
FIGS. 1 to 6 , the air circulation fan of the present invention comprises arod 10, amotor 20, afan 30 andmultiple filtering members 40. - The
rod 10 has afixing portion 11 on the top end thereof and thefixing portion 11 is fixed to aRC truss 50 or a solid board, and the lower end of therod 10 extends through aceiling 51 and reaches into the room. - The
motor 20 is connected to the lower end of therod 10 and wires (not shown) from themotor 20 are connected to the power source and switch so as to control the operation of themotor 20. - The
fan 30 comprises abase 31, anannular cover 32, multipleupright blades 33,multiple shafts 34 and acap 35. Thebase 31 is connected to themotor 20 bymultiple bolts 310 so that thebase 31 is driven by themotor 20 to rotate in one direction. Thebase 31 has aprotrusion 311 extending downward from the central portion thereof. Theprotrusion 311 has a curved outer surface and the diameter of theprotrusion 311 is gradually reduced along the curvature of the curved outer surface of theprotrusion 311. Thecap 35 is connected to the underside of theprotrusion 311. Thebase 31 has arecess 312 defined in the top thereof and themotor 20 is accommodated in therecess 312. Thebase 31 hasmultiple blade slots 313 defined in the underside thereof and theblade slots 313 are located around theprotrusion 311. Thebase 31 has multipleengaging holes 314 defined in the underside thereof and theengaging holes 314 are located close to a periphery of thebase 31. Thecover 32 is horizontally connected to the underside of thebase 31 so as to form aspace 36 between thebase 31 and thecover 32. Theblades 33 are connected between thebase 31 and thecover 32. Theblades 33 are arranged along the periphery of thefan 30.Multiple outlets 37 are defined between theblades 33 and communicate with thespace 36. Aninlet 38 is defined through the underside of thefan 30 and communicates with thespace 36. Thecover 32 has a U-shaped cross section. Thecover 32 hasmultiple restriction slots 320 defined in the top thereof, eachrestriction slot 320 is defined between two restriction blocks. Thecover 32 hasmultiple positioning members 321 on the top thereof. The top end and the bottom end of each of theblades 33 are respectively engaged with theblade slot 313 and therestriction slot 320 corresponding thereto. Theblades 33 each is posed an angle relative to the radial direction of thebase 31, so that air in the lower portion of the room is sucked from theinlet 38 and circulates by the rotation of theblades 33, and passes through the filteringmembers 40 and flows out from theoutlets 37. - Each of the
blades 33 has apassage 330 defined axially therethrough. Ashaft 34 extends through thepassage 330 of each of theblades 33. Two ends of each of theshafts 34 are connected to thebase 31 and thecover 32 respectively. The top end of each of theshafts 34 is connected with anut 340. - The
