Title:
WOOD STOVE
Document Type and Number:
WIPO Patent Application WO/2011/018819
Kind Code:
A1
Abstract:
Two vent holes (12, 13), that are used to introduce outside air into a combustion chamber by means of natural aeration, are created at locations at the lower end of an outer wall part (4f) of the combustion chamber (4) of a wood stove (1). Rectangular open frames (14, 15) are attached to vent holes (12, 13), and opening/closing covers (16, 17) are attached to the rectangular open frames (14, 15). Outside air introduced through the vent holes (12, 13) is directed tangentially along the circular inner circumferential surface (4g) of the outer wall part (4f) of the combustion chamber (4) by the rectangular open frames (14, 15) and the opening/closing covers (16, 17), and an uprising swirling air flow (B) is formed inside the combustion chamber, whereby wood combustion efficiency can be improved. The opening/closing covers (16, 17) can be used to automatically change the degree of opening of the vent holes (12, 13) according to the combustion chamber temperature, and the interior of the combustion chamber can be prevented from overheating.
