Problems solved by technology
[0002] Most of the fresh air fans on the market are in the form of a fixed entry and exit in the corresponding direction or a separate volute assembly. The installation form cannot adjust the connection direction according to the site conditions. Due to too many elbows, the air volume loss is increased, and the equipment is not flexible. To meet the later needs of customers (same as customer reasons or environmental changes cannot flexibly increase or decrease functions)

The invention discloses a novel combined type air supplying and discharging universal fan which comprises a mainframe shell (3), a fan (4) arranged on the mainframe shell (3), a power supply cord and a switch; wherein the top and the bottom of the mainframe shell (3) are closed, the three ones of the four side surfaces are respectively provided with an air inlet (2), and the fourth side surface is provided with an air outlet (7); the air outlet (7) is selectively matched with an air outlet unit (5) or a pipeline interface (9); the air inlet (2) of the side surface of the mainframe shell (3) relative to the air outlet (7) is selectively matched with an air inlet unit (1) or the pipeline interface (9), and the other two air inlets (2) are selectively matched with a blind plate (8) or the pipeline interface (9); the inner wall of the mainframe shell (3) is fixed with a sound-absorbing panel (8). The invention has the advantages of the simple and reasonable structure, one machine with three purposes, air supplying and discharging, the middle pressurization, reducing the loss of the air quantity, saving energy sources, suitable for the standard mass production and reducing the cost, and thereby is applied to various pipeline ventilation systems.
Description
technical field [0001] The invention relates to an air supply and exhaust device, in particular to a combined general fresh air blower for air supply and exhaust. Background technique [0002] Most of the fresh air fans on the market are in the form of a fixed entry and exit in the corresponding direction or a separate volute assembly. The installation form cannot adjust the connection direction according to the site conditions. Due to too many elbows, the air volume loss is increased, and the equipment is not flexible. Meet the customer's later needs (the same as the customer's reasons or environmental changes cannot flexibly increase or decrease functions). Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a combined general-purpose fresh air blower for supplying and exhausting air that reduces air volume loss and is flexible in equipment installation. [0004] The purpose of the present ...
