Air-outlet windproof and energy-saving device

Abstract

The invention discloses an air-outlet windproof and energy-saving device and aims to provide a device which is arranged on the air outlet of smoke exhaustion equipment such as all kinds of gas water heaters, range hoods and the like and can prevent smoke from flowing backwards. The air-outlet windproof and energy-saving device comprises a wind scooper [1], a variable flow cone [2], an exhaust pipe [3], a wind limitation disk [4], and a connector [5]; the smoke is exhausted outwards from an interface of the exhaust pipe to a large port and a small port of the wind scooper; and overflowing sectional area is widened segment by segment, smoke is smoothly exhausted without backward flow, and wind in all directions does not obstruct smoke exhaustion, so the air-outlet windproof and energy-saving device is particularly suitable for a stove-piped gas water heater and the smoke is exhausted by utilizing raising force of hot smoke and the smoke does not need to be forcibly exhausted. When the windproof and energy-saving device is used for exhaust equipment such as forced exhaustion type gas water heaters, ventilators and the like, the device can lower the forced exhaustion power, reduce heat loss, realize energy conservation and carbon emission reduction, improve energy utilization rate, and reduce noise and pollution; and a rectangular or circular large-scale air-outlet windproof and energy-saving device which is formed by arranging and combining a plurality of air-outlet windproof and energy-saving devices and used for a rectangular or circular large-area air outlet has the advantages of small longitudinal size and attractive appearance.

Description

technical field [0001] The invention relates to a device installed on the exhaust outlet of the smoke exhaust equipment, more specifically, the invention relates to a windproof and energy-saving device for the exhaust outlet that prevents the smoke from being poured back by wind force and is beneficial to exhaust the smoke. Background technique [0002] Under the existing technology, strong wind pours back from the exhaust pipe, causing the gas water heater to stop midway, fail to ignite, ignite and explode, and carbon monoxide poisoning to cause personal casualties and property damage. large, increasing energy consumption. The range hood is exhausted outdoors, which will cause the fume to flow backward due to strong winds. Exhaust to the public airway. When you don’t exhaust the oil fume, other people’s house is exhausting it, causing a pressure difference between the inside and outside of the public airway and causing the smoke to smell. be polluted.
