PROBLEM TO BE SOLVED: To equalize the temperature distribution inside a room with very simple structure by providing with the air intake hole member of a sheet heater having insulation to the outside and can generate Joule heat on the inner side of a cylindrical member held to a partition wall. SOLUTION: An air intake hole member 1 comprises a cylinder part 2, a flange part 3 being held to a partition wall W, a sliding lid 4 that is able to control the width of outer air path and a sheet heater 5. The sheet heater 5 can be a flexible cylindrical form, a square envelope form or rigid one. The cylinder part 2, the flange part 3, etc., are formed with heat resistant plastic. The sheet heater 5 has the heating circuit formed by etching a metal foil with a pattern inside insulating protection sheets mainly made of silicon rubber. The heater 5 is formed to a cylindrical form, supported by the inner surface of the cylinder part 2 and the area of contacting outer air is increased. Setting of temperature is done by a thermostat 8. With this, a vicinity of the air intake hole member inside the room is prevented from being cooled by the intake outer air. |
