Title: Hot water feeder housing type range hood
Inventor: SUZUKI TOSHIAKI
IPC: F24F7/06
Filed: 1990-09-05
Abstract: PURPOSE:To prevent dewing from generating in a range hood due to a high temperature exhaust burning gas by extending a duct from above a heat exchanger and positioning an exhaust port in the neighborhood of the suction port of a blower. CONSTITUTION:A hot water feeder 29 has a suction port 35 communicating with a casing 30, being projected from the lower portion of the left side face plate 21d of a hood body 21 and opened, draws the burning air of a burner 31. The hot water feeder 29 has an exhaust port 36 positioned in the neighborhood of the suction port 23 of a blower 24 without being connected thereto by a duct 37 for exhausting the exhaust burning gas of the burner 31. The exhaust burning gas of the burner 31 does not spread in a space inside the hood body 21 from an exhaust port 36 via the duct 37 but is blown by the blower 24 to be surely discharged from an exhaust port 27 via an exhaust duct 28. Further, since the exhaust ducts themselves are heated by exhaust heat generated in cooking even when a hot water supply is stopped, dewing is not generated in the hood body and the exhaust ducts themselves, preventing an apparatus from being damaged by dewing.

The gas which has not undergone combustion flows into a fuel supply line 6 and passes backward through a fuel electrode interruption valve 5 and an auxiliary-burner fuel control valve 9 before being introduced into an auxiliary burner 11. The residual air also flows backward in an air supply line 22 and passes through an air exhaust line 28 before being introduced into the auxiliary burner 11. Compressed air supplied from an air compressor 15 is also supplied into the auxiliary burner 11. A mixture gas composed of the compressed gas and the gas which has not undergone combustion is burned with a burner 12.
