Description

  The present invention relates to air conditioning equipment for non-room spaces in buildings such as stairs, corridors, dressing rooms, washrooms, and bathrooms.

  In winter, the temperature difference between the living room and the non-living room is severe. For this reason, when a senior citizen moves from a living room to a non-living room (dressing room, bathroom) and takes off clothes or takes a bath, the so-called heat shock, which causes the body to adapt to a sudden temperature change and fall down, becomes a problem. ing. As a countermeasure against heat shock, it is effective to keep non-room spaces such as corridors (spaces above the corridor floors) and stairs (spaces above the stairs) warm to reduce the temperature difference in the house.

  However, since the corridor is narrow, it is difficult to secure a space for installing air conditioning equipment. Therefore, conventionally, for example, as described in Japanese Utility Model Laid-Open No. 6-69624 (Patent Document 1), Japanese Patent Application Laid-Open No. 7-190469 (Patent Document 2), and Japanese Patent No. 3230930 (Patent Document 3), It is known to install an air conditioner in the space under the stairs.

Japanese Utility Model Publication No. 6-69624 JP 7-190469 A Japanese Patent No. 3230930

  However, the conventional air conditioning equipment has the following problems. That is, in the air-conditioning facilities of Patent Documents 1 to 3, the temperature of the living room is adjusted by connecting the air conditioner and the living room with the air duct, so that the effect of warming the non-residential space cannot be expected so much. However, it is only necessary to provide an air outlet and intake port for the stair kick formed of plate material, and to install an air conditioner in the space below the stairs, when heating the air conditioner and heating the non-room space on the stairs The wall surface of the space under the stairs (back of the stairs) will be directly warmed, the temperature difference between the tread surface of the stairs (step surface) and the wall of the space under the stairs (back surface of the stairs) will increase, and the stairs will dry and shrink. It may cause a sound.

  In view of the above-described circumstances, the present invention provides an air conditioning structure under a staircase that can effectively adjust the temperature of a non-living room connected to a space above a staircase and that is effective in preventing the sound of a staircase made of a plate material. For the purpose.

  For this purpose, the air conditioning structure under the stairs according to the present invention sucks in the air taken into the space below the stairs from the air intake that is installed in the space below the stairs and the air intake and the air outlet provided in the stairs of the building.
