| 摘要 |
The present application discloses a combustion apparatus including: an air supply/exhaust port formed such that an air supply passage surrounds the outside of an exhaust passage; and an air supply port in which an air supply passage is formed. This combustion apparatus is configured such that in a case where this apparatus is installed in the double-pipe system, the air supply passage of the air supply port is closed, whereas in a case where it is installed in the separate-pipe system, the air supply passage of the air supply/exhaust port is closed. The combustion apparatus includes: a supplied-air temperature sensor; and a guide member, which is located near the air supply passage of the air supply/exhaust port or the air supply passage of the air supply port, and by which air flowing into the space in the housing is guided to the supplied-air temperature sensor. |

1. A combustion apparatus that can selectively be installed in a double-pipe system using a double pipe in which an exhaust pipe is accommodated in an air supply pipe or in a separate-pipe system using an exhaust pipe and an air supply pipe separately, the apparatus comprising:
an air supply/exhaust port formed such that an air supply passage surrounds the outside of an exhaust passage, and an air supply port in which an air supply passage is formed,
wherein both the air supply passage of the air supply/exhaust port and the air supply passage of the air supply port communicate with the space in a housing, andwherein in a case where the apparatus is installed in the double-pipe system, the air supply passage of the air supply port is closed, whereas in a case where the apparatus is installed in the separate-pipe system, the air supply passage of the air supply/exhaust port is closed; a supplied-air temperature sensor that measures, in the space in the housing, the temperature of supplied air, and a guide member, which is located near the air supply passage of the air supply/exhaust port or the air supply passage of the air supply port, and by which air flowing into the space in the housing from the air supply passage of the air supply/exhaust port or from the air supply passage of the air supply port is guided to the supplied-air temperature sensor. |
