Description

Technical Field

[0001] The utility model belongs to the field of integrated firewood stoves, and specifically relates to a novel integrated firewood stove structure. Background Art

[0002] The integrated wood-burning stove is an integrated stove that combines a wood-burning stove and a range hood.

[0003] The power control of a wood-burning stove is mainly determined by the fuel and the air flow into the furnace. In existing wood-burning stoves, air can actively flow into the furnace because a range hood is connected to the flue. When the range hood is working, the flue and the furnace generate negative pressure to inhale air. Generally, the air flow is controlled by the range hood to control the combustion power.

[0004] This structure for controlling combustion power requires the use of circuits to control the fan power of the range hood and to control the flow rate of inhaled air. However, when the fan power decreases, the suction force of the range hood on the inside of the furnace decreases, the range hood's ability to absorb oil fumes will become weaker, and the oil fumes cannot be completely sucked into the flue, affecting the use environment of the integrated stove.

[0005] In view of this, the present utility model is proposed. Utility Model Content
