Description

Air compensation device and supply and exhaust hearth system

Technical field

The utility model relates to a kind of air compensation devices, further relate to a kind of supply and exhaust hearth system.

Background technique

With rapid economic development, the quantity of civilian kitchen and commercial kitchen is quickly increased, cook's working environment Temperature is high and often sucks many housewives of harmful oil smoke and cook therefore obtained tuberculosis or even obtained lung cancer, traditional benefit Wind is there are energy consumption height, the problem of the isolation of cook's oil smoke and the not strong low efficiency of cooling specific aim and water conservancy diversion low efficiency.Main performance By multivane mouth or other air outlets to indoor benefit wind on the furred ceiling other than enclosure, since the system of air supply pipeline hinders Power causes air supply efficiency low, and the uneven problem of each air outlet air-supply, the serious relatively low, specific aim of whole efficiency is not strong and cannot be same When multidirectional blast.Besides the round mouth air outlet in adjustable direction is equipped on petticoat pipe, similar to the air-supply of the passenger on aircraft Mouthful, the plane of structure region that this air outlet influences fluid spilling is small, and protrusion petticoat pipe is more, influences the operating space of user, mixes up It can only be blown toward a direction behind direction, limitation and specific aim are very low, to user's air-supply and cannot influence fluid motion simultaneously The region in direction is blown, and it is multi-purpose cannot to achieve the effect that a wind, and equally exists that air supply efficiency is low, and each air outlet air-supply is uneven The problem of, the serious relatively low problem of whole efficiency.

Utility model content

Air-supply specific aim in order to solve the problems, such as existing air supply device is not strong, and the utility model provides a kind of benefit wind dress It sets.The air compensation device is provided with the first air outlet directed downwardly and the second air outlet facing forward, the air-flow energy of the first air outlet discharge It is enough that airflow barrier is formed between pernicious gas and user, to protect the health of user；The air-flow of second air outlet blowout Can make pernicious gas acceleration flow to fume extractor, thus increase collection cigarette area and reduce pernicious gas it is excessive.Benefit wind dress The specific aim for not only increasing air-supply is set, the efficiency of smoke evacuation and air-supply is also improved, more can protect the health of user.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

The beneficial effects of the utility model are: the air compensation device is equipped with multiple air outlets, multiple air outlet can be distinguished It blows into user's air-supply and petticoat pipe.The air-flow blown to user can form air-flow between pernicious gas and user Barrier can provide a healthy new wind environment to user, to protect the health of user.The air-flow blown into petticoat pipe Can make pernicious gas acceleration flow to petticoat pipe, thus increase collection cigarette area and reduce pernicious gas it is excessive.The air compensation device can Specific aim blows or simultaneously to a direction air-supply or multidirectional blast, raising smoke exhaust efficiency, improves air supply efficiency energy conservation and environmental protection.
