FIELD: designs of vacuum cleaners that may by used with single-use paper filter or with multiple filter according to selection of user. ^ SUBSTANCE: housing of vacuum cleaner includes chamber for mounting motor and dust accumulating chamber separated from chamber for motor by means of partition and communicated with chamber for motor through passage provided in partition. Dust accumulating chamber includes air intake in its wall and it has outlet to outside. Dust collecting means having single use paper filter and long-period multiple-use filter are arranged in dust accumulating chamber for separating dust from air sucked through air intake. Dust accumulating chamber has members for reliable mounting of paper filter or multiple-use filter. The last includes body whose outline is defined by front surface having first opening, upper and lower surfaces passing from upper and lower edges of front surface, by both lateral surfaces passing from both edges of front surface and having first and second guiding grooves and by back surface passing from upper and lower surfaces and from both lateral surfaces and having second opening. Filtering device is mounted with possibility of dismounting it in second opening of back surface. There are fastening members for separately mounting filtering device in second opening. In variant of invention vacuum cleaner includes cover detachably mounted in opening of filter body that is made of porous plastics that is why it works as filter. ^ EFFECT: lowered investment for designing vacuum cleaner, reduced cost of maintaining and repairing it. ^ 7 cl, 12 dwg |
