Claims (9)

1. Вытяжной воздушный вентилятор, предназначенный для размещения на здании на выходе вентиляционного контура, имеющий нормальный выпускной проход для выпуска воздуха наружу, отличающийся тем, что содержит деформируемую часть (30), закрывающую проход наружу, и выполненную с возможностью деформации во время пожара под действием расхода горячих газов в вентиляторе, таким образом, чтобы образовать выпускной проход, дополнительный к нормальному выпускному проходу с увеличением полного сечения прохода наружу.1. An exhaust air fan designed to be installed on the building at the outlet of the ventilation circuit, having a normal exhaust passage for letting air out, characterized in that it contains a deformable part (30) that closes the passage outward and is capable of deformation during a fire under the action of the flow of hot gases in the fan, so as to form an exhaust passage additional to the normal exhaust passage with an increase in the total cross section of the passage to the outside. 2. Вытяжной воздушный вентилятор по п. 1, отличающийся тем, что деформируемая часть (30) расположена под нормальным выпускным проходом для выпуска воздуха.2. An exhaust air fan according to claim 1, characterized in that the deformable part (30) is located under the normal exhaust passage for exhausting air. 3. Вытяжной воздушный вентилятор по п. 2, отличающийся тем, что деформируемая часть (30) образует расширяющуюся обечайку, расширяющуюся в направлении наружу по мере приближения к нормальному выпускному проходу для выпуска воздуха.3. An exhaust air fan according to claim 2, characterized in that the deformable part (30) forms an expanding casing expanding outward as it approaches the normal exhaust passage for exhausting air. 4. Вытяжной воздушный вентилятор по п. 3, отличающийся тем, что включает в себя по порядку, начиная снизу, цилиндр (2) основания, расширяющуюся обечайку (30) деформируемой части, соединенную плотной посадкой с указанным цилиндром, нормальный выпускной проход цилиндрической формы для воздуха и колпак (14), накрывающий указанный проход.4. An exhaust air fan according to claim 3, characterized in that it includes, in order, starting from the bottom, a base cylinder (2), an expanding shell of a deformable part (30) connected by a tight fit to the specified cylinder, a normal cylindrical exhaust passage for air and a cap (14) covering the specified passage. 5. Вытяжной воздушный вентилятор по любому из пп. 1-4, отличающийся тем, что деформируемая часть (30) содержит пластмассу, не создающую горящей капли во время пожара, форма которой придана методом литья или термоформования.5. Exhaust air fan according to any one of paragraphs. 1-4, characterized in that the deformable part (30) contains plastic that does not create a burning drop during a fire, the shape of which is given by casting or thermoforming. 6. Вытяжной воздушный вентилятор по любому из пп. 1-5, отличающийся тем, что включает в себя вытяжную воздушную турбину, приводимую в действие двигателем.6. Exhaust air fan according to any one of paragraphs. 1-5, characterized in that it includes an exhaust air turbine driven by an engine. 7. Вытяжной воздушный вентилятор по п. 6, отличающийся тем, что вытяжная турбина содержит пластмассу, выполненную с возможностью размягчения и сгибания под действием температуры горячих газов в вентиляторе.7. The exhaust air fan according to claim 6, characterized in that the exhaust turbine contains plastic made with the possibility of softening and bending under the action of the temperature of the hot gases in the fan. 8. Вытяжной воздушный вентилятор по любому из пп. 1-7, отличающийся тем, что нормальный выпускной проход содержит защитную решетку (50).8. Exhaust air fan according to any one of paragraphs. 1-7, characterized in that the normal exhaust passage contains a protective grill (50). 9. Вытяжной воздушный вентилятор по любому из пп. 1-8, отличающийся тем, что сечение дополнительного выпускного прохода вентилятора равно по меньшей мере сечению нормального выпускного прохода.9. Exhaust air fan according to any one of paragraphs. 1-8, characterized in that the cross section of the additional exhaust passage of the fan is equal to at least the cross section of the normal exhaust passage.
