FIG. 1 is a cross-sectional view illustrating a ceiling-type air conditioner blowing fan according to a preferred embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating a rotary vane, and FIG. 3 is a plan view showing a rotary vane. A ceiling-type air conditioner blowing fan, which is one embodiment, includes a ceiling-type air conditioner having a structure in which a heat exchanger and a blowing fan for generating cold air are installed inside a ceiling wall surface 1, or a ceiling-type air conditioner equipped with a chiller supply duct for supplying heat- It is applicable.

The ceiling-type air conditioner blowing fan includes driving means (10) mounted on a wall surface (1) provided with a discharge port through which cold air is discharged, a rotating blade (20) rotatably mounted by the driving means (10) And an air blowing nozzle 30 mounted on the outer circumferential surface of the rotary vane 20 for discharging cool air.

The rotary vane 20 is rotatably fixed to a rotary shaft 40 mounted on the wall surface 1. The rotary vane 20 includes a shaft portion 22 into which the rotary shaft 40 is inserted and a plurality of vane portions 23 radially protruding from the circumferential surface of the shaft portion 22. The rotary vane 20 has a plurality of vanes 23 protruding radially to form a screw shape. The rotary vane 20 generates a strong air flow toward the downward direction where the cool air is discharged while rotating. The outer shape of the rotary vane 20 is the same as the rotary vane structure of the ceiling fan.

A guide passage (21) for guiding cool air is formed inside the rotary vane (20), and the blowing nozzle (30) communicates with the guide passage (21). One side of the guide passage (21) communicates with the cold air discharge opening formed in the wall surface (1). The guide passage 21 penetrates the inside of the shaft portion 22 and extends to the inside of the wing portion 23.

The blowing nozzle (30) communicates with the guide passage (21) formed in the blade portion (23). The blowing nozzle (30) is formed in a direction perpendicular to the longitudinal direction of the wing (23) so that the cool air is discharged toward the front side of the rotary vane (20). 2, the blowing nozzle 30 may be inclined so as to approach the center axis of the wing 23 toward the end of the wing 23. When the blowing nozzle 30 is formed to be inclined toward the outward direction at the end of the wing portion 23, the discharged cold air can spread further. That is, as shown in Fig. 2, the angle of inclination of each blowing nozzle 30 with respect to the center line of the rotary vane 20 is formed such that angle a is larger than angle b and angle b is larger than angle c. The angle a is close to 90 degrees, and the angle c is formed close to 0 degrees.

The driving means 10 is formed of a motor mounted on the wall surface 1 so as to rotate the shaft portion 22. [ In the present invention, the structure in which the driving means 10 rotates the outer circumferential surface of the shaft portion 22 has been described as an example, but it is also possible to apply a motor having a structure for rotating the center shaft.

The rotary shaft (40) has its end fixed to the wall surface (1) and passes through the center of the shaft portion (22) of the rotary vane (20). The shaft portion (21) of the rotary vane (20) is rotatably supported on the rotary shaft (40). At the end of the rotary shaft (40), a locking protrusion for preventing the detachment of the rotary vane (20) is formed, and a lamp (41) is mounted on the bottom surface exposed to the outside. In addition to the illumination lamps 41, jewelry may be attached.

1, an air purifying filter 50 is provided in the flow passage of the discharge port 20 through which cool air is guided. The air cleaning filter 50 is preferably replaceable and can be replaced with a perfume, a mosquito repellent, or the like in accordance with a user's request.

The operation of the ceiling-type air conditioner blowing fan, which is a preferred embodiment of the present invention, is as follows.

In the case of an air conditioner in which a separate heat exchanger and a blower fan are provided on the ceiling, the process of sucking the cold air through the air outlet is such that the room air is sucked, the heat exchanger exchanges heat to generate cool air, There is a case where the cool air is discharged toward the discharge port and a case where the cool air is discharged to the discharge port by being communicated with the cool air supply duct for supplying the heat exchanged cool air. The cool air discharged through the discharge port is supplied to the inside of the rotary vane 20 through the guide passage 21. At this time, the rotary vane 20 is forced to blow the room air downward while rotating.

The supplied cold air is discharged to the room through the blowing nozzle 30. At this time, the discharged cold air is quickly diffused into the room by being mixed with the air blown by the rotating blades 20.

In addition, the cool air supplied through the discharge port may be discharged to the outside by the blowing air generated by the rotation of the rotary vane 20. That is, the cold air can be discharged to the air blowing nozzle 30 through the guide passage 21 through the air outlet by the air blown by the rotary vane 20.

When the rotary vane 20 is rotated without operating the air conditioner, the indoor air is sucked through the separate suction port, and then guided to the discharge port. The air is guided to the discharge nozzle 30 through the discharge passage, Can be performed. At this time, the air guided through the guide passage 21 can perform the purifying action of the indoor air while passing through the air purifying filter 50. If the air purifying filter 50 is replaced with a fragrance, a mosquito repellent, etc., functions other than indoor air purification can be performed.

Likewise, a ceiling-type air conditioner blowing fan according to a second preferred embodiment of the present invention has a structure in which a ceiling-type air conditioner is equipped with a heat exchanger 61 and a fan 62, as shown in FIGS. A heat exchange chamber (61a) is provided inside the roof type air conditioner. One side of the heat exchange chamber (61a) is connected to the discharge port (2), and the other side is connected to the inflow path (63) through which the outside air flows. At the entrance of the inflow path 63, a damper 64 for controlling the direction of air to be sucked is rotatably mounted.

As shown in Fig. 4, the damper 64 is kept inclined in a closing direction, and outside air is introduced through the inflow path 63 in this state. The introduced outside air is forcibly blown to the heat exchanger 61 by the fan 62, and the temperature of the air is lowered to generate cool air. The cold air whose temperature has been lowered is guided to the guide passage 21 of the rotary vane 20 through the discharge port 2.

 At this time, the rotary vane 20 is forced to blow the room air downward while rotating. The supplied cold air is discharged to the room through the blowing nozzle 30. At this time, the discharged cold air is quickly diffused into the room by being mixed with the air blown by the rotating blades 20.

In addition, the cool air supplied through the discharge port may be discharged to the outside by the blowing air generated by the rotation of the rotary vane 20. That is, the cold air can be discharged to the air blowing nozzle 30 through the guide passage 21 through the air outlet by the air blown by the rotary vane 20.

5, when the rotary vane 20 is rotated in the opposite direction without operating the air conditioner, the indoor air is blown in the upward direction and the damper 64 is converted into the open state. Then, the blown air flows into the inflow path (63). The indoor air is sucked through the separate inflow passage 63 and then guided to the discharge port and discharged through the discharge passage to the blowing nozzle 30 through the guide passage 21. [ At this time, the air guided through the guide passage 21 can perform the purifying action of the indoor air while passing through the air purifying filter 50. If the air purifying filter 50 is replaced with a fragrance, a mosquito repellent, etc., functions other than indoor air purification can be performed.

As described above, the ceiling-type air conditioner blowing fan according to the present invention promotes the diffusion of the cold air discharged through the discharge port by using the forced air blown by the rotation of the rotary vane.

In the ceiling-type air conditioner blowing fan according to the present invention, when the rotating blades are rotated in a state where the air conditioner is not operated, the room air is purified by the air cleaning filter while passing through the inside of the roof air conditioner. It is also possible to install a fragrance or mosquito repelling agent in place of the air purifying filter.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
