INTELLIGENT AIR CURTAIN FUME HOOD

摘要

The present invention provides an intelligent air curtain fume hood, which includes cabinet, inclined air curtain module, intelligent window control module and processing module. Feature of the present invention is that the inclined air curtain module is the use of inclined air flow field distribution generated during the operation of shelter in the work space, and with variable air volume theory in order to reduce the gas leaking chance to further achieve security and energy saving effect.

主权项

1. An intelligent air curtain fume hood, comprising:
a cabinet comprising a working platform, an observation window and an exhaust device; the working platform disposed in the cabinet and forming a work space with the observation window for operating; an inclined air curtain module providing an air curtain flow field to prevent gas leaking to environment, the inclined air curtains module comprising an air-out device and an air weight control device; the air-out device disposed on the working platform and adjacent to one side of the observation window, the air-out device and the exhaust device spaced a distance, the air-out device spraying air flow upwardly to the exhaust device to form an inclined air flow field and controlling a matched proportion of an air-out amount of the air-out device and an air-exhaust amount of the exhaust device to form the air curtain flow field by the air weight control device; an intelligent window control module comprising a window driving device controlling operation of the observation window, and a window positioning detection device detecting a relative position of the observation window and returning a position signal; and a processing module disposed in the cabinet and electrically connected with the cabinet, the inclined air curtain module and the intelligent window control module; the processing module receiving the position signal and adjusting air volumes of the exhaust device and the air-out device by a variable air volume theory.
