As Figure 1-5, electric fan 100 according to the present invention comprises housing 110, lid 120 and rotary unit 130.
Housing 110 has polygonal frame shape.Housing 110 has the polygonal one or more section of formation.
In the present invention, housing 110 is depicted as the streamline-shaped with two sections or the square configuration with four sections.The shape of housing 110 is not limited to certain concrete shape.
Specifically, as shown in Figure 4, the housing 110 with streamline-shaped is configured to have two column structures, thus makes space 111 spaced.Impeller 132 is uprightly furnished with in each space 111.
As shown in Figure 4, construct the housing 110 of square configuration as follows, described mode is that formation two row is connected each other continuously with the space 111 of two row sections.Level or be vertically provided with impeller 132 in each space in the space 111 being formed at top, bottom, left part and right part position.
Generally speaking, the housing 110 with this polygonal shape defines annular shape, thus makes the first opening 114 be formed in the central part of housing 110.
Here, the main body of polygonal housing 110 is called as framework.
Each section of polygonal frame defining therein respective space 111.Import 112 is formed on the outer surface of the border of housing 110, and exports 113 and be formed on the internal surface of the border of housing 110.Import 112 is communicated with space 111 with outlet 113.
Rotary unit 130 comprises the impeller 132 be arranged in each space 111, and is constructed to make when impeller 132 is rotated by driver element 133, and outside air is inhaled in space 111 by import 112, is then discharged into outside by outlet 113.
Each impeller 132 comprises the axle 132a with predetermined length and the multiple blade 132b arranged around the external peripheral surface radial direction of axle 132a.
Multiple driver element 133 is arranged on each impeller 132.The running shaft 132a of the motor of each driver element 133 is connected on the axle 132a of corresponding impeller 132, thus impeller 132 directly can be rotated by the active force produced by driver element 133.
In addition, each impeller 132 is supported by support 140 in corresponding space 111.
Support 140 comprises connected element 141, fixed component 142, supporting part 144 and connection bracket 145.
Connected element 141 has the predetermined length corresponding with the length of impeller 132.
In addition, fixed component 142 is bending from the upper end of connected element 141, and has attachment hole 143, and axle 132a is couple on fixed component 142 by this attachment hole.
Supporting part 144 is bending from the lower end of connected element 141, and is couple to the lower end of driver element 133.
Connection bracket 145 is separately positioned on fixed component 142 and supporting part 144, and is integrally couple on the fixed support 115 of the correspondence be arranged in space 111.
So, support 140 is arranged in space 111 by this way, and described mode makes connection bracket 145 be couple to be arranged on the fixed support 115 in space 111.Between the connected element 141 that each impeller 132 being provided with driver element 133 is installed in corresponding support 140 and fixed component 142.
In other words, adopt support 140 to be arranged on by impeller 132 in each space 111 in the section being defined in toroidal shell 110, be therefore convenient to the installation of impeller 132, the manufacturing efficiency of electric fan can be improved whereby.
In the electric fan 100 with said structure, when driver element 133 rotary blade 132, outside air is inhaled in space 111 by import 112, is then discharged into outside by outlet 113.
Lid 120 is arranged on the front portion of housing 110 in the mode directly contacted, and has the second opening 121 be communicated with the first opening 114 wherein, thus the air provided by outlet 113 is discharged from the second opening 121.
Preferably, the internal surface of the second opening 121 tilts as follows, and described mode is make the second opening 121 cross section be increase from its rear end forward end.
The air of discharging from one or more outlet 113 moves to the second opening 121 through the first opening 114; And air stream partly combines each other, therefore increased sharply emission flow.
That is, the air pressure step-down in the first opening 114 of housing 110, the flow of air is relatively high herein; The pressure of the air simultaneously in the second opening 121 becomes relative increase.As a result, because the active force of air is from high side to low side, make outside air therewith through housing 110 with relatively high speed through the air of housing 110, because which form constant and strong air stream.
As mentioned above, in electric fan 100 according to the present invention, lid 120 is coupled to each other with the housing 110 with frame shape, and rotary unit 130 is installed in inner space 111.Electric fan 100 runs as follows, which makes outside air suck in space 111 by import 112, therefore pressure in space 111 increase, then the pressure owing to increasing in space 111 makes air discharge from outlet 113 with high flow capacity, outside air thus around lid 120 is through lid 120, thus produce air stream, and owing to making the flow of air increase at air from the air pressure difference before electric fan discharge.Therefore, the monsoon intensity of electric fan can increase further.
Although for explanatory purposes, describing the preferred embodiments of the present invention, those skilled in the art will appreciate that when not departing from claims invention disclosed scope and spirit, various amendment, it is also possible for increasing and substituting.
