The fan motor 18 is configured to rotationally drive the movable body 18a around a fixed core. By fixing the base of the fan 16 to the outer peripheral surface of the movable body 18a, the fan motor 18 rotates with the rotation of the movable body 18a. The fan 16 is driven to rotate.
Thus, by arranging the fan 16 and the movable body 18a on the same plane, the thickness of the rotating body is minimized.

The fan 16 has a function of introducing air from the side of the apparatus and blowing out the introduced air from the apparatus along the ceiling surface 10. For this reason, the fan 16 includes an intake blade 16a for sucking air and the air supply blade 1 for sending air.
6b consists of two parts. Inlet blade 16
a is arranged on the center side of the fan 16,
b is disposed on the outer edge side of the fan 16. Inlet blade 16
a is formed in a flat plate shape having a gentle inclination angle. One end of the air supply blade 16b is connected to an end of the intake blade 16a,
The other end side is formed so as to be curved in an arc shape to have an upright shape.

The fan 16 of the embodiment has an intake blade 16a.
However, it is needless to say that the intake blade 16a and the air supply blade 16b may be formed integrally with each other. As a configuration of the fan 16, it is important that an air suction portion (introduction portion) is provided on the center portion side and an air sending portion is provided on the outer edge side, and the intake blade portion 16a and the air supply blade portion 16b are provided. Is not limited to the shape of the embodiment.

In FIG. 2, reference numeral 14 denotes the above-mentioned lighting fixture mounting plate, and reference numeral 20 denotes a shielding plate which is arranged at a distance from the lighting fixture mounting plate 14 and is arranged on the front surface of the fan 16. The shielding plate 20 is provided so as to shield the opening of the device main body having the side surface opened so as to be vertically divided into two parts, and is arranged so that the edge protrudes outward from the outer peripheral edge of the lighting fixture mounting plate 14. In the embodiment, the edge side of the shielding plate 20 is arranged to be slightly inclined downward, but this takes into consideration the intake of air into the apparatus main body and the supply of air from the apparatus main body. Since the lighting fixture mounting plate 14 is formed in a rectangular shape, in the present embodiment, the shielding plate 20 is formed in a frame shape as shown in FIG. Shield plate 2
0 is mounted slightly apart from the lighting fixture mounting plate 14 in order to make the opening A between the lighting fixture mounting plate 14 and the shielding plate 20 an inflow portion for introducing air into the device.

As shown in FIG. 3, the shielding plate 20 is provided with an opening hole 22a which opens in a range where the intake blade 16a rotates. Reference numeral 22 denotes an auxiliary plate provided inside the frame-shaped shielding plate 20 for forming the circular opening hole 22a. Of course, the shielding plate 20 and the auxiliary plate 22 may be integrally formed as a shielding plate. When the illuminating body 12 is formed in a circular shape, the shielding plate 20 can be modified to be formed in a circular shape in accordance with the illuminating body 12.

As shown in FIG. 2, the shield plate 20 is disposed at the front side of the intake blade 16a on the intake side, while the air supply blade 16b is located between the rear surface of the shield plate 20 and the ceiling surface 10. Arrange to rotate. Reference numeral 24 denotes the ceiling of the apparatus body.
It is a mounting plate to be attached to. The air supply blade 16b is arranged to rotate at the opening between the mounting plate 24 and the shielding plate 20. The position of the extension end of the shield plate 20 is
b is extended beyond the tip of the air supply blade 16b so that the air delivered by the rotation of the air supply blade 16b is
This is because the air is guided along the ceiling surface 10 and is blown out along the ceiling surface 10.

As described above, by arranging the fan 16 and the shielding plate 20, air flows in from the side of the apparatus main body, that is, between the shielding plate 20 and the lighting fixture mounting plate 14, as the fan 16 rotates. Then, after passing through the opening hole 22a, air is discharged from between the shielding plate 20 and the mounting plate 24. That is, the indoor air convection device takes in the air in the room from below the device main body into the device, and generates an air flow that sends the air to the periphery of the device along the ceiling surface 10.

The apparatus was actually mounted, and the temperature distribution in the room and the flow of air were observed. The dimensions of each part of the apparatus used in the experiment are as follows. The radius of the opening hole 22a is 640 mm. A set of five intake blades and air supply blades. The size of the intake blade 16a is about 100 mm x 200 mm. The area of the air supply blade 16b is about 40 mm x 220 mm. Lighting fixture mounting plate approx. 650mm x 650mm. Shielding plate about 1030
mm × 1030 mm. The ceiling height is 2060mm. Floor area 26
m ² . 98 rotations / minute of the fan motor.

The flow of air in the room was performed by observing the flow of smoke. According to the observation results, as shown in FIG. 1, the air sent from the apparatus main body along the ceiling surface 10 goes downward along the wall surface. The flow of air along the wall surface does not appear clearly at a distance of 150 to 200 mm from the wall surface. That is, it can be seen that the air flow sent from the device is a flow along the ceiling surface 10 and the wall surface. The downward air flow along the wall surface is 14
Clear flow disappears at a height of about 00 mm. From below the height, the flow is directed toward the apparatus body attached to the ceiling surface 10.

The observation result of the air flow is shown in FIG.
The air flow sent from the device body attached to the ceiling 1
0 means that a steady flow returning from the floor surface and the wall surface to the apparatus main body is formed so as to flow down along the wall surface and wrap the whole room. Fan 1 of the present embodiment
The rotation speed of 6 is not so fast. However, forming a steady flow surrounding the entire room even with such a gentle flow is extremely effective in terms of making the entire room a uniform temperature. Actually, fan 1
It was confirmed that it was effective to generate a steady flow with a slow air flow from the fact that an effective result was not always obtained when the rotation speed of 6 was increased.

The temperature distribution in the room was measured by placing a thermometer at a height of 200 mm from the floor and at a height of 2400 mm from the floor. A warm air heater was installed on the floor as a heating source, and the temperature was set so that the temperature became 24 ° at a position 4 m away from the heater. The following results were obtained by measuring how the room temperature changes with time when the outside air temperature was -1 ° C and the room air convection device was used and not used. Note that the floor surface means a temperature at a height of 200 mm from the floor surface, and the ceiling surface means a temperature at a height of 2400 mm from the floor surface.

[0022]

[Table 1]

In the experimental results shown in Table 1, the room temperature rises only gradually after the start of heating. This is because it takes time for the entire room to warm up due to heat being absorbed by the wall surface. The outside temperature is -7 ° C
In the case where the temperature setting of the warm air heating device is 24 ° C., the ceiling surface temperature is 20 ° C. after 30 minutes by using the indoor air convection device,
The floor temperature was 16 ° C., the ceiling temperature was 24 ° C. after 60 minutes, and the floor temperature was 19 ° C. When the outside air temperature is 10 ° C. and the temperature setting of the hot air heating device is 24 ° C., when the indoor air convection device is not used, the ceiling temperature is 28 ° C. and the floor temperature is 18 ° C.
However, when using the indoor air convection device,
The ceiling temperature was 23 ° C and the floor temperature was 20 ° C.

The above measurement results of the indoor temperature distribution show that the indoor air convection apparatus according to the present invention is very effective in making the indoor temperature uniform. That is, when the outside air temperature is relatively high at about 10 ° C., the temperature difference between the ceiling surface and the floor surface is reduced by 3 ° C. by using the indoor air convection device.
When the outside air temperature is relatively low, such as -1 ° C, the temperature difference between the ceiling and floor can be reduced to about 4 ° C by using an indoor air convection device. It becomes possible. In addition, when a room with high heat insulation is used, it is possible to further reduce the temperature difference between the ceiling surface and the floor surface as compared with the above experimental results.

By uniformizing the room temperature in this manner, the entire room can be efficiently heated during heating, and the entire room can be heated comfortably by increasing the heating effect particularly on the floor surface. And the heating efficiency can be increased. Actually, by making the indoor temperature uniform by effectively convection of the indoor air, it is possible to shorten the combustion time of the heater and save energy.

Further, the indoor air convection device according to the present invention causes the air to wrap around from the ceiling surface and the wall surface of the room toward the center of the room. Because the air does not hit the person directly in the room and the fan is not visible from the outside by taking in air from the side of the device, there is no sense of incongruity even during use, making it extremely natural There is an advantage that it is possible to cool and heat.

Since the indoor air convection device according to the present invention has the function of circulating the air in the room, a filter for removing dust in the air is provided in the main body of the device, and the indoor air convection device is simultaneously operated while operating. It is also possible to adopt a configuration for purifying indoor air. In FIG. 2, a filter 26 is provided at an opening between the lighting fixture mounting plate 14 and the shielding plate 20. Alternatively, activated carbon may be disposed in the apparatus main body to perform deodorization, moisture absorption, and the like.

Further, as a method of ventilating the air in the room, it is possible to adopt a configuration in which the outside air is taken in by utilizing the suction action of the indoor air convection device. In FIG. 2, reference numeral 28 denotes an outside air intake pipe installed in communication with the main body of the indoor air convection device. In the embodiment, the outside air intake pipe 2
8 is used as a fixed core of the fan motor 18, and one end of the outside air intake pipe 28 is opened at the back of the lighting fixture mounting plate 14 through the core of the fan motor 18. In addition,
A power supply line for driving the fan motor 18 may be passed through the outside air intake pipe 28.

The other end of the outside air intake pipe 28 is provided so as to communicate with the outside of the building, and the outside air is taken in little by little from the outside air intake pipe 28 by an intake action generated by the rotation of the fan 16. When the fan 16 rotates, the air in the room flows in from the opening between the lighting fixture mounting plate 14 and the shielding plate 20, and the air is sent out by the air supply blade 16b. The open end has a negative pressure, and the outside air intake pipe 28
The outside air comes to be sucked in from. When such a configuration is adopted, the room temperature can be made uniform while ventilating by taking in outside air, and there is an advantage that a more comfortable indoor environment can be obtained.

[0030]

As described above, the indoor air convection apparatus according to the present invention introduces air in a room into the apparatus main body attached to the ceiling surface and sends out air from the apparatus main body along the ceiling surface. It can generate an air flow that wraps around the entire room, which can cause effective convection in the room even with a gentle air flow, and effectively uniform the temperature of the entire room Can be In addition, since the illuminating body attached to the ceiling surface can be installed together, the installation space is advantageous, more effective convection action can be achieved, and the appearance is good.
