[Prior Art]

 Conventionally, the function of a lighting fixture that aims to illuminate the interior of the room and the elimination of the temperature unevenness phenomenon where warm air gathers near the ceiling during heating by forcedly circulating the air in the room and the feet do not heat up or the feet cool only during cooling The illuminator with a circulator that combines the functions of a circulator for the purpose of integrating the same ceiling-mounted fixture to save space, improve aesthetics, and improve air circulation efficiency by installing the circulator in the center of the room. Proposed. FIGS. 9 and 10 are sectional views showing a conventional illuminator with a circulator shown in, for example, Japanese Utility Model Laid-Open No. 59-125010 and air circulation when the illuminator with a circulator is mounted in a room. It is a state diagram. In the figure, reference numeral 1 denotes an illuminator, which is attached to the ceiling 2 near the center thereof. Reference numeral 3 is a case of a lighting fixture, to which a translucent acrylic resin cover 4 can be attached. A plurality of fluorescent lamps 5 are arranged in the illuminator 1 near the outer circumference. 6 is an incandescent lamp, which is arranged near the center of the luminaire 1 at four corners of a quadrangle. Reference numeral 7 designates an air inflow hole for incandescent lamps, which is formed in four places on the cover 4 in correspondence with the position of the incandescent lamp 6. Occurs to the extent that Reference numeral 9 is an air inflow hole, which is formed on the side surface of the lighting fixture 1. A circulator fan 10 is provided at the central position in the lighting fixture 1 so as to blow air downward. Reference numeral 11 denotes an air outlet, which has a hole formed in the cover 4 corresponding to the fan 10 and provided with a louver 12 composed of a large number of holes. Reference numeral 13 indicates a fan motor. Reference numeral 14 denotes an indoor air circulation path generated by the fan motor.

The conventional illuminator with a circulator is configured as described above, and by rotating the motor 13 and rotating the fan 10, the air inlet gap of the air inflow hole 9 and the incandescent lamp / air inflow hole 7 is introduced. 8 sucks the indoor air into the luminaire 1 with a circulator, blows the air downwards from the air outlet 11 at the center of the luminaire 1 through the louver 12, and the indoor air is shown in the air circulation path 14. It is designed to circulate.

[0004]

[Problems to be solved by the device]

 In the conventional luminaire with a circulator as described above, the luminaire 1 is attached to the center of the ceiling 2, the air outlet 11 is provided in the central portion of the cover 4, and the fan 10 for the circulator allows the air to flow. Since the air is blown downward, the air in the room becomes like the air circulation path 14, and only the air in the vicinity of the center of the room can circulate, and the air in the vicinity of the wall of the room is difficult to circulate. Therefore, there is a problem in that the temperature inside the room differs between the central area and near the wall, and it is difficult to make the room temperature uniform. Further, since the air outlet 11 is provided in the central portion of the cover 4 and the circulator fan 10 blows out the air downward, the blown air reaches strongly under the lighting device 1 and directly under it. When there is a person in the vicinity, there is also a problem that it becomes uncomfortable due to the draft feeling due to the influence of air flow.

The present invention was made in order to solve the problems of the above-described conventional ones, and the temperature of the room is controlled by sufficiently circulating the air in the room not only near the center of the room but also near the wall and near the ceiling. The purpose is to reduce the difference and make the temperature uniform throughout the room. Furthermore, it is an object of the present invention to provide a lighting fixture with a circulator that eliminates the draft feeling caused by the influence of the air flow in the room and improves comfort.

[0006]

[Means for Solving the Problems]

 In the luminaire with a circulator according to the present invention, in order to generate an air flow for effectively circulating the air in the room widely throughout the room, one motor is provided in the luminaire, and the rotation shaft of the motor is Configure so that it is oriented vertically. The rotary shaft is constructed so that both ends project from the motor, and one circulator fan is attached to each of the upper and lower ends of the rotary shaft.

Further, in order to reverse the directions of the air flows generated by the fan, the twisting directions of the blades of the fan fixed to the upper end and the lower end of the motor are made opposite to each other.

Further, in order to make the temperature inside the room uniform, air is provided at the center of the case, which is the upper part of the lighting equipment, and the center of the cover, which is the lower part, facing the two fans. It is provided with a suction port.

A partition plate that divides the air blown out by the two fans into an upper layer portion and a lower layer portion is provided inside the lighting fixture, and the side surface of the case and the side surface of the cover are provided with the upper layer portion and the lower layer portion. A corresponding air outlet is provided.

Further, the partition plate is provided with several ventilation holes so that air having a high temperature flowing above the partition plate and air having a low temperature flowing below the partition plate are mixed with each other.

[0011]

[Action]

 Since the luminaire with a circulator in this invention is configured as described above, when the lower fan attached to the lower end of the rotation shaft of the motor rotates by rotating the motor, it faces the lower fan. Air near the center of the room flows into the luminaire through the lower air inlet provided in the center of the cover. Then, due to the effect of the partition plate provided in the luminaire, the air flow changes its direction laterally and is blown obliquely downward through the air lower outlet port provided on the side surface of the cover to circulate in the room. .. In addition, the upper fan and the lower fan attached to the upper and lower ends of the motor's rotating shaft rotate in the same direction at the same time by rotating the motor, but the twisting directions of the blades are opposite to each other. The air near the wall of the room passes through the vicinity of the ceiling and flows into the luminaire through the upper air inlet on the upper surface of the center of the case facing the upper fan. Due to the effect of the partition plate installed in the lighting equipment, the air flow changes its direction laterally, and is blown and circulates obliquely downward through the air upper outlet on the side of the case.

[Effect of the device]

 Since the present invention is configured as described above, the following effects can be obtained.

The structure of two fans provided in the lighting fixture, which are different in the twisting direction of the blades from each other, and an air intake port, an air outlet port, and a partition plate provided in the lighting fixture, Since there are two routes, a route that circulates in the center of the room and a route that circulates from the wall to the ceiling, it is possible to mix the air in the entire room, making it easier to equalize the temperature inside the room and Warm air gathers only near the ceiling, and it is possible to eliminate the temperature unevenness phenomenon, such as the fact that your feet do not warm and that your feet just cool during cooling.

In addition, since the airflow near the luminaire is not a blow from the top but a suction, and the blow from the side of the luminaire is also obliquely downward, it is close to the bottom. Even if there are people in the room, the draft feeling caused by the influence of the air flow is eliminated and an environment with increased comfort is obtained.

Further, since the partition plate is provided with the ventilation holes, the air having a high temperature and the air having a low temperature are mixed in the lighting device and are blown out in a state where the temperature is made uniform, so that the temperature in the room can be made more uniform.

Since the dustproof filter is provided at the air inlet of the lighting equipment, dust in the air can be removed, and a hygienic environment can be obtained.
