Smoke exhausting channel fresh air system and using method

Abstract

The invention relates to a smoke exhausting channel fresh air system and a using method. According to the technical scheme, the bottom of a public smoke channel is connected with a dredging pipeline system, the dredging pipeline system is in an L shape, a dredging device is connected to the bottom of the dredging pipeline system and provided with a receiving controller, the public smoke channel isconnected with a range hood of each layer through a smoke pipe, a pressure detector is installed in the public smoke channel, and a suction fan and a wind cap are installed on the top of the public smoke channel. The system has the beneficial effects that the smoke exhausting efficiency is up to 99%, and less smoke remains. In addition, during daily, except for cooking time, the suction fan is started in a timing manner or periodically, negative pressure is formed in the public smoke channel, thus gas in rooms of all layers is sucked into the public smoke channel and exhausted, the fresh airventilating function is achieved, the installing expense of the fresh air system is reduced, the system is applicable to most houses, the fresh air system is used by common families, the indoor area is not occupied, and the price is reasonable and relatively low.

Description

technical field [0001] The invention relates to an indoor smoke exhaust and ventilation device and method, in particular to a fresh air system for exhaust air duct and its use method. Background technique [0002] Indoor pollution, except for decoration and other factors, the biggest source of pollution is the kitchen, which is the hardest hit area of ​​household air pollution. Research from the Indoor Environment Monitoring Center of China Interior Decoration Association shows that there are two main pollution sources in the kitchen: one is coal gas and liquefied petroleum gas. Such as the kitchen fire source, may release harmful gases such as carbon monoxide and nitrogen oxides when burning; the second is the cooking fumes produced when cooking dishes, and the harmful substances radon, formaldehyde, and other harmful substances that cause cancer and leukemia when food is heated at high temperature Benzene, ammonia and esters, trichlorethylene. Indoor environmental polluti...

Problems solved by technology

[0003] Due to the unsmooth exhaust of the flue, poor sealing and other reasons, these harmful substances have passed through the flue to the neighbor's house. During the installation of the existing building flue, the bottom of the bottom flue is blocked. During the process, due to the low air pressure in the flue, the oil fume recharges, resulting in a string of smoke and smell! The existing exhaust system has high cost, low smoke exhaust rate, large residual smoke, short service life, occupies kitchen area, and is noisy

[0004] In addition, the existing fresh air system generally adds a new system when decorating the house, which generates an investment. Moreover, the installation of indoor pipelines causes some space to be occupied in the small house, and Small houses are not suitable for installing a fresh air system, so that the fresh air system can only be applied in small groups such as large houses or villas
