Description

[Detailed explanation of the invention] This invention relates to an improvement of a wind fan that allows air intake and exhaust air to be taken in by rotating the main body panel, and the operating part is exposed to the outside during both intake and exhaust operations. The purpose of this invention is to obtain a safe wind fan in which electrical parts are not exposed to rainwater or the like.

Hereinafter, one embodiment of this invention will be described with reference to FIGS.
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 rotatable approximately at the center. Reference numeral 5 denotes a front panel forming the front surface (indoor side) of this main body panel, which is formed into a substantially semi-cylindrical shape, and has a vortex stabilizer 6 of the blower, which will be described later, integrally formed therein, and has a concave portion 7 formed therein. An outlet 8 is provided.
9 is a discharge side grill provided at this discharge port; 10
The recess 7 is located on the right side of the main body panel 4 when facing the front.
11 is a fin provided so that the air blowing direction can be arbitrarily changed; 12 is a rear panel forming the rear surface (outdoor side) of the main body panel 4; It is formed into a substantially semi-cylindrical shape and is provided with a suction port 13. 14 is a filter provided at the intake port 13, 15 is an intake side grill provided outside this filter, 16 is a blower installed inside the wind fan body, and the above-mentioned vortex stabilizer 6 and rear guide wall 17 It is formed from a casing 18 consisting of a rotary blade 19, an electric motor (not shown), and the like. The front panel 5 and the rear panel 12 are assembled so as to be separable by screws 20, and are formed into a circular shape.

In the wind fan configured as described above, when taking in outside air, the main body panel 4 is
As shown in the figure, the discharge port 8 is placed on the indoor side, and the suction port 1 is placed on the indoor side.
3 is located outside the room and the blower 16 is operated to blow outside air from the suction port 13 through the filter 14 and into the room from the discharge port 8. On the other hand, when discharging indoor air, rotate the main body panel 4 so that the operation part 10 faces the front and is located on the left side, position the suction port 13 on the indoor side and the discharge port 8 on the outdoor side, and then This is done by driving 16. Since the switch is rotated and used in this manner, the operation part 10 of the switch is formed so as not to protrude beyond the circumference so as not to impede the rotation, and this non-protrusion also provides safety. In addition, the fan casing 18
Instead of rotating the main body 4 to change the air flow direction, the main body 4 is rotated to change the direction of the air flow.
The flow direction in the filter 14 is constant, and dust that has once adhered to the filter 14 does not scatter as it does when changing the flow, which is also sanitary. In addition, air intake and exhaust can be performed by simply moving the operating section 10 from the right side to the left side inside the room, and the operation can be easily performed from the indoor side.Moreover, since the operating section does not come into contact with rainwater or the like, there is no risk of electric shock or the like.

In the above embodiment, the operating section 10 is provided on the right side and is moved from the right side to the left side, but the same effect can be obtained even if the operating section 10 is provided on the left side and moved from the left side to the right side. can get.

As explained above, the operation part provided on the main body panel is located on the indoor side when the main body panel is rotated so that the discharge port is on the indoor side and the suction port is on the outdoor side with respect to the frame. When the main body panel is rotated so that the discharge port is on the outdoor side and the suction port is on the indoor side with respect to the frame, it is operable to be located on the other side of the indoor side. Since it is located in a recess formed in the main body panel, the operation part can be located on the indoor side for both intake and exhaust operations, and is especially useful for wind fans installed on windows. It will be safe.
Additionally, since the operating section is not located outdoors, it is safe from rainwater, etc., and there is no risk of electric shock.
