Is set. FIG. 4 is a cross-sectional view of the ventilation heater 5 0 1 installed on the ceiling 39 of a room such as a bathroom, and shows the periphery of the circulation fan 5. The flange portion 10 of the main body 1 is located in the room 3 8 of the room, and is installed in the installation opening 40 of the ceiling 3 9. The main body 1 is arranged outside the room 3 8 with respect to the ceiling 3 9. Circulating blower 5 includes a motor-4 2 provided on the top surface 4 1 of the main body 1, a fan 4 3 directly connected to motor ₄ 2, the fan 4 3 orifice plate is provided as the suction side to the lower side of the 4 4 and. The outlet side 4 5 of the fan 4 3 is connected to the heater unit 6. In the evening unit 6, the connection part on the outlet side 45 opens and communicates. The lower surface 46 of the heater unit 6 is open, and the halogen heaters 4 7 A and 4 7 B are attached as heating elements inside the heater unit 6. On the back of the halogen heaters 4 7 A and 4 7 B, there is a reflector 4 9 formed with ventilation slits 4 8 to secure a predetermined air flow. The reflector 4 9 is a heater 4 7 A, 4 7 The heat rays from B are reflected to the lower surface 4 6 of unit 6. An opening 6 A is formed in the lower surface 46 of the heater unit 6, and a guard 50 made of iron wire in a lattice shape is attached to the opening 6 A. Louver 1 2 frame 1 8 is between louver 1 2 lower surface 1 5 and ceiling 3 9 Block.

Since the frame bar 1 2 is attached to the main body 1 so that the frame 1 8 contacts the flange portion 10, the inside of the frame 1 8 forms a suction air passage 51. The frame 17 of the heater unit 6 is inserted into the opening 16 provided in the lower surface 15 of the louver 1 2. A gap σ 1 is provided between the frame 17 and the opening 16 so as to prevent heat conduction. When the louver 1 2 is securely installed on the main body 1, the lower surface 4 6 of the heater unit 6 protrudes from the lower surface 15 of the louver 1 2 by a length σ 2 (about 2 mm). When the ventilation heater 5 0 1 is operated, the fan 4 3 rotates and the air in the room 3 8 is sucked from the suction port 2 4 of the louver 1 2. The sucked air enters the heater unit 6 from the outlet side 45, passes through the ventilation slit 48 of the reflector plate 49, and is heated by the halogen heaters 47 A and 47 B, and then heated. Evening unit 6 is blown out from the bottom surface 4 6 to the room 3 8 as heating air. The blown-out air: diffuses into the room 38, descends, and rises along the walls of the room. The rising air reaches the ceiling 39 and returns to the suction port 24 located in the vicinity of the ceiling 39, so that an air flow that circulates almost the entire room 38 is formed.

The louver 1 2 inlet 2 4 has a larger area at the center 2 1 A than the side 2 1 B, so the louver out of the air sucked by the fan 4 3 — 1 2 2 1 A The air sucked in through the suction port 2 4 reaches the side surface 5 2 1 along the frame 17 of the heater unit 6 through the suction air passage 51 and forms an air flow sucked into the fan 43. Suction port 2 4 louver 1 Side 2 2 Side 1 2 1 B suction port 2 4 has a smaller area than the central 2 1 A side suction port 2 4 The air sucked from the suction port 2 4 The air is sucked into fan 4 3 as it is. In order to make the fan 43 suck air more efficiently or to reduce the wind speed from the side suction port 24, a lower surface suction port 26 is provided on the lower surface 15 of the louver 12. May be. Considering the air flow from the suction port 24, the lower surface suction port 26 is opposed to the suction side 45 of the fan 43 and is located at a position away from the center side. Therefore, the bottom suction port 2 6 The unit 6 can be separated from the lower surface 4 6.

The inside of the frame 1 8 of the louver 1 2 is a space in the main body 1. In addition, the outside of the frame 18 is a space communicating with the interior 38 of the bathroom, and an air flow by circulation and an air flow induced by it are formed near the ceiling 39. Therefore, a space where air stagnates is not formed between the rubber bar 1 2 and the ceiling 39. The air flow along the ceiling 39 promotes the evaporation of moisture condensed on the ceiling 39, prevents the dripping of water droplets, and prevents the generation of mold.

When the halogen heaters 4 7 A and 4 7 B are energized, the heaters themselves become hot and the circulating airflow is heated and radiant heat is emitted. Since the lower surface 4 6 of the heater unit 6 protrudes from the lower surface 15 of the louver 1 2, this radiant heat is radiated into the room 3 8 without directly irradiating the louver 1 2, and the louver 1 2 It is not affected by heat. Therefore, the rubber 12 can be formed of a material having low heat resistance such as resin. By confirming that the frame 1 7 of the heater unit 6 protrudes from the louver 1 2, it can be confirmed that the louver 1 2 is correctly attached. Can be installed efficiently.

Since the louver 1 2 is installed with the frame 1 8 in contact with the flange 10, its dimensions are not affected by variations in the installation site such as the thickness of the ceiling 39. Therefore, the louver 1 2 can be installed accurately. That is, it can be seen that the lower surface 46 of the heater unit 6 is not in the proper position unless the louver 12 is correctly attached. In this embodiment, the frame 18 of the rubber bar 1 2 contacts the flange portion 10, but the frame 18 is formed along the outer periphery of the flange portion 10, and the frame 18 is attached to the ceiling 39. You may touch.

In addition, the guide bar 2 7 is hooked on the louver holding metal fitting 12 to match the position at which the lumber 1 2 can be attached to the main body 1. Therefore, when screwing the filter 1 2 to the main body 1, it is not necessary to find the screw hole of the main body 1, so that it is not necessary to support the filter 1 2 in the meantime. Can be attached. The louver 1 2 will not come off and fall even when the screw is removed during maintenance. In the ventilation heater 5 0 1 according to the embodiment, the area of the lower surface 15 of the louver 1 2 facing the main body 1 opening 9 of the louver 1 2 is surrounded by the frame 18 of the louver 1 2. Larger than the area formed by being surrounded by the flange portion 10. As a result, the periphery of the lower surface 15 of the louver 1 2 protrudes, so that even if water droplets condensed on the frame 1 8 of the ruby bar 1 2 drop along the wall surface 18 A of the frame 1 8, Received and does not drip directly. Further, the protruding portion of the lower surface 15 of the louver 1 2 makes it difficult to see the connection portion between the frame 1 8 of the louver 1 2 and the main body 1 or the ceiling 3 9.

In addition, since the louver 12 has a large strength due to the curved lower surface 15, the louver 12 can be produced with a small amount of material, and the suction port 24, which serves as an air passage for the circulation blower and the ventilation blower, can be enlarged. As a result, the resistance in the air path is reduced, and the driving noise is reduced and the driving efficiency is improved. Industrial applicability

In the heating and ventilating apparatus according to the present invention, the occurrence of force drift near the louver can be reduced.
