Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the improvement of a wind fan, and its purpose is to provide a wind fan with good moldability and assembly workability.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 is a frame attached to a window, and this frame includes an upper frame 2 and a lower frame 3.
It is formed so that it can freely slide up and down. Reference numeral 4 denotes a main body panel of the wind fan attached to the frame 1, which is formed in a cylindrical shape and is formed to be freely rotatable approximately at the center. Reference numeral 5 denotes a front panel forming the front surface of this main body panel, which is formed in a substantially semi-cylindrical shape, and has a vortex stabilizer 6 of the blower, which will be described later, integrally formed therein, a recess 7, and a discharge port 8. It is being Reference numeral 9 denotes a discharge-side grill provided at the outlet, reference numeral 10 indicates an operation unit such as a switch, which is provided so that its tip does not protrude into the recess 7, and reference numeral 11 is provided so that the air blowing direction cannot be changed arbitrarily. The fin 12 is a rear panel forming the rear surface of the main body panel 4, and is formed into a substantially semi-cylindrical shape, and is provided with a suction port 13. 14 is a filter provided at the suction port 13, 15 is an intake side grill provided outside the filter, and 16 is a blower installed inside the wind fan body. In the blower 16, a rotary blade 19 is covered by a casing 18 consisting of the vortex stabilizer 6 and the rear guide wall 17, and an electric motor (not shown) for driving the rotary blade 19 is connected to the front and rear panels 5, 12. It is arranged inside the lower end. In addition, the above casing 1
8 is arranged on the inner peripheral side of the front and rear panels 5 and 12,
At one side between the discharge port 8 and the suction port 13, the guide wall 17 on one side is attached to the rear panel 12 with a fixing screw 20.
b and is integrated with the rear panel 12, and on the other side between the discharge port 8 and the suction port 13, the vortex stabilizer 6 of the front panel 5 is arranged on the discharge port 8 side, and the rear panel 5 is fixed on the suction port 13 side. A guide wall 17 on the other side integrally molded with the panel 12 is arranged,
This guide wall 17 and the vortex stabilizer 6 are brought into contact with each other. In addition, the front panel 5 and the rear panel 12 are fastened on one side with a fixing screw 20a via the guide wall 17 on one side, and on the other side are directly fastened with a fixing screw 20a, so that they can be combined in a divisible manner. Main body panel 4 in cylindrical shape
is formed.

In the wind fan configured as described above, by operating the blower 16, outside air is blown from the suction port 13 through the filter 14 and into the room from the discharge port 8. On the other hand, when indoor air is to be discharged, the main body panel 4 is rotated and the blower 16 is operated.
Since the switch is used by rotating in this manner, the operation part 10 of the switch is formed so as not to protrude from the circumferential outer wall so as not to impede the rotation, and it is also safer because it does not protrude in this way. Moreover, since the main body 4 is rotated to change the direction of air flow, instead of rotating the fan casing 18 to change the air flow as in the conventional case, the flow direction in the filter 14 is constant, and once Filter 14
It is also hygienic because the dust attached to the flow does not scatter as it does when changing the flow. Furthermore, since each of the front panel 5 and the rear panel 12 is formed into a semi-cylindrical shape, and the vortex stabilizer 6 is integrally molded on the front panel 5, the front panel 5 and the rear panel 12 can be easily molded. Therefore, during assembly, there is no need to attach the vortex stabilizer 6 to the front panel 5 with screws or the like, and the assembly time is shortened. Furthermore, since there is no need to attach the vortex stabilizer 6 to the front panel 5 with screws or the like, there is no joint between them, so rainwater or the like that enters from the outside will not accumulate, and rust will not occur. In the above embodiment, the front panel 5 is provided with the vortex stabilizer 6, but the rear panel 12 is provided with the vortex stabilizer 6.
may be provided. (In this case, it will be an exhaust type.) As explained above, the wind fan of this invention is formed by forming a cylindrical main body panel into two roughly semi-cylindrical halves, a front panel and a rear panel, and a front panel or a rear panel. Since the vortex stabilizer is integrally molded on either side, it is easy to integrally mold the panel and the vortex stabilizer.By integrally molding, there is no need to separately attach the vortex stabilizer to the panel. There are no joints during installation, as shown in the figure, so there is no risk of rainwater entering from the outside, and rust and corrosion caused by rainwater can be prevented. Furthermore, since there is no need to assemble the vortex stabilizer during assembly, there is an effect that the assembly work time is significantly shortened.
