Title:
DEODORIZING DEVICE
Document Type and Number:
Japanese Patent JP3684664
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To restrain smell, generated at the time of heating and reproducing a deodorizing catalyst, provided in a combustion chamber, and improve the handling convenience of a deodorizing device by heating the deodorizing catalyst quickly.
SOLUTION: A deodorizing device is provided with a combustion chamber 2, in which exhaust gas, generated in the combustion of gas, is mixed into air, taken from the outside of the instrument, a fan 3 for sending and supplying the mixed warm-air to the outside of the instrument, a deodorizing catalyst 10, provided in a duct after mixing the exhaust gas in the combustion chamber 2 into air and decomposing the adsorbed smell by heating to reproduce it, a temperature detector 6, an operation switch 7 and a control means 14. Upon starting combustion, the fan 3 is turned at a low speed until the temperature of the temperature detector 6 becomes a predetermined temperature and the deodorizing catalyst 10, into which smell is adsorbed, is heated quickly to a predetermined temperature to increase the capacity of oxidization and decomposition of the deodorizing catalyst 10, oxidizing and decomposing the smell at a temperature higher than the predetermined temperature, and reduce the smell, discharged at a temperature lower than the predetermined temperature in a stage on the half way of the oxidizing decomposition.
