Hybrid ventilation apparatus capable of both natural and forced ventilation

摘要

Disclosed herein is a hybrid ventilation apparatus capable of both natural and forced ventilation. In the case of a natural ventilation mode, a worm gear is rotated in a normal direction by drive force of a drive unit under control of a control unit so that a pressing member engages with a rotation guide protrusion and rotates a damper, thus opening a flow passage, and then the worm gear is reversely rotated by drive force of the drive unit to return the pressing member to its original position, thus allowing a user to rotate a roller upwards and downwards and rotate the damper so that the degree of opening of the flow passage can be adjusted. Thereby, rapid inflow of outdoor air can be blocked, and a cold graft phenomenon, in which the temperature of indoor air rapidly drops, can be prevented.

主权项

1. A hybrid ventilation apparatus (100) for naturally and forcedly ventilating indoor air of a building, comprising:
a housing (110) comprising: a base plate (111) on which a natural ventilation unit (120) for naturally ventilating indoor air of the building and a forced ventilation unit (130) for forcedly ventilating the indoor air are installed; and a cover (112) mounted to the base plate (111), the cover (112) receiving and protecting the natural ventilation unit (120) and the forced ventilation unit (130) therein, with an inlet port (112′) provided on the cover (112), the inlet port (112′) being open downwards; a natural ventilation unit (120) installed in the housing (110), the a natural ventilation unit (120) having therein flow passage (121a′) communicating with the inlet port (112′), wherein a worm gear (123b) is rotated in a normal direction by drive force of a drive unit (123) under control of a control unit (140) and, simultaneously, pressing members (123c) that protrude from the worm gear (123b) engage with rotation guide protrusions (122c) and rotates dampers (122) and (122′) and open the flow passage (121a′), and after the flow passage (121a′) has been opened, the worm gear (123b) is reversely rotated by drive force of the drive unit (123) to return the pressing members (123c) to original positions thereof, and rollers (124b) and (124b′) are rotated upwards or downwards by a user so that the dampers (122) and (122′) are rotated, whereby a degree of opening of the flow passage (121a′) is adjusted such that the indoor air is naturally ventilated through the flow passage (121′a); a forced ventilation unit (130) comprising a forced ventilation member (131) provided above the natural ventilation unit (120) and closely mounted to a sidewall of the housing (110) that is in an indoor side of the building, the forced ventilation unit (130) having a heat exchange element (132) therein, the forced ventilation unit (130) comprising a supply fan (133a) and an exhaust fan (133b) rotating to forcedly ventilate the indoor air under control of the control unit (140), and an air flow sensor (150) installed in an end of the flow passage (121a′) to measure a flow and pressure of air.
