The domestic apparatus for the detection and expulsion of gas is provided with a casing (2) which includes an encapsulated motor (1) which, by means of the fan propellers (3), sucks, through the grid (7) visible from the inside of the house wherein is installed the apparatus, the accumulated and localised gas, through the grid (10), by means of the sensor (5) which actuates the motor (1), and sound and light warning alarms (9) arranged next to the light indicator (8) which indicates the proper operation of the apparatus. The gas is extracted through the expulsion conduit (6) which, after a short section from the grid (7), describes a curved lateral section channel having a flexion point or is branched to two or more similar conduits (6) which describe facing trajectories, diametrically opposite and equidistant to each other, terminating at external grids (4) for each conduit; the motor (1) is centered in a same horizontal plan with respect to the fan (3) and is encapsulated in a sealed housing wherein the extracted gas can not enter because of the sealed connection point (12) between the axis (11) of the fan (3) which actuates the motor (1) and its encapsulated housing. Alternatingly, there are provided two or more conduits (6) between which the motor (1) remains in position with a 90 DEG rotation with respect to the arrangement the motor has when only one conduit (6) is provided. |
