Controllable flue gas discharge structure and stove

Abstract

The invention provides a controllable flue gas discharge structure and a stove, and belongs to the field of stove accessories. The controllable flue gas discharge structure comprises a flue gas collecting hood for covering a furnace mouth, and a chimney connecting pipe which communicates with the flue gas collecting hood and is provided with a chimney connector and an air inlet with an adjustableopening area. By increasing the opening area of the air inlet during fire banking, so that suction force of a chimney to outside air is gradually increased through the air inlet, the suction force ofthe chimney to the interior of the flue gas collecting hood is reduced, combustion in a furnace is slowed down, although suction force of the chimney to the interior of the flue gas collecting hood isreduced, a channel from the flue gas collecting hood to the chimney through the chimney connecting pipe is always kept unobstructed, flue gas in the flue gas collecting hood can be discharged outdoorfrom the chimney through the chimney connecting pipe, and carbon monoxide poisoning of indoor personnel is avoided. By adopting the controllable flue gas discharge structure for the stove, the effectthat flue gas is completely discharged outdoor during fire banking can be ensured, and carbon monoxide poisoning of indoor personnel is avoided.

Description

technical field [0001] The invention belongs to the technical field of stove accessories, and more specifically relates to a controllable smoke discharge structure and a stove. Background technique [0002] Existing stoves are equipped with a smoke collection hood at the furnace mouth, and the smoke collection hood is connected with the chimney. The gas flow in the furnace is improved, so that the fire is strong. [0003] When there is no need for the flame of the stove to be too strong, it is generally used to block the communication port between the smoke collection hood and the chimney to reduce the suction force of the chimney to the smoke collection hood, so that the gas flow in the furnace is slowed down, and the combustion in the furnace is slowed down. However, in some cases, after the communication port between the fume collection hood and the chimney is blocked, although the combustion in the furnace will slow down, a large amount of smoke will still be produced, ...
