The invention relates to the field of household appliances, namely, to household cleaners dry cleaning.

Most manufactured household cleaners dry cleaning consist of a case, the air suction unit, dust collector filters.

Famous Hoover ARIANNE Hoover company (UK), (GIAS Service Hoover & Candy, Technical Information Book 2nd Edition, Candy, V1, Floorcare Products, p. 20-22), having a housing with a separated element in the form of a wall, which divides it into a compartment of the bag and compartment. In aggregate compartment is air suction unit having inlet and outlet openings and preloaded to the wall of the inlet, and a mechanism for winding the cord with power cord. In the wall of the holes located opposite the inlet of the air suction unit and covered with a preliminary filter. Compartment is closed by a cover. In the lid with holes air outlet is blocked by a filter, closed his cap from the exhaust holes. Case in aggregate compartment has an insertion opening for the power cord, fitted with a lid with a groove for passing a cord. Compartment dust collector also closed with a lid having an aperture for connection of a hose.

Air suction unit when enabled, creates a vacuum in the compartment dust collector and the air through a hose inserted into the hole cover of the dust collection unit, is sucked in from the EC of the bag. Then sucked in air through a prefilter and openings in the casing wall enters into the inlet of the air suction unit, which throws out the air in the compartment. The air from the propulsion compartment out through the holes in the cover aggregate cover, filter and then through the holes of the filter cover into the room, and through the slot cover input cord.

The disadvantage of this vacuum cleaner is the air outlet of the propulsion compartment not only through the filter and through the slot cover input power cord. Therefore, part of the air with dust, milled in Assembly into fine particles, and wear products unit is thrown into the room, bypassing the filter. It is known that fine dust in the room is deposited within a few days and when it is inhaled it can cause allergies.

The closest analogue of the claimed group of inventions is known a vacuum cleaner, comprising a housing holds the separating element with through-holes, forming a compartment with a lid having outlet openings, and compartment box with lid that has an input socket, pre-filter, overlapping holes of the separation element mounted in the aggregate compartment damper air suction unit with input and output open the s and made in the aggregate compartment channel for the passage of air from the outlet air suction unit to the outlet openings of the cover aggregate cover (US 6336244 And, 08.01.2002).

The disadvantage of this vacuum cleaner are its large size and weight, which is caused by the presence of a special corps of aggregate compartment with a channel for passage of air from the outlet air suction unit to the outlet cover aggregate cover.

The task of the group of inventions is the creation of a vacuum cleaner, providing technical result consists in reducing the size and weight of the vacuum cleaner without compromising the degree of filter vent air to improve ease of use of the cleaner and reduce the cost of production.

This technical result in cleaner, comprising a housing holds the separating element with through-holes, forming a compartment with a lid having outlet openings, and compartment box with lid that has an input socket, pre-filter, overlapping holes of the separation element mounted in the aggregate compartment damper air suction unit with input and output holes and made in the aggregate compartment channel for the passage of air from the outlet air suction unit to the outlet openings of the cover aggregate cover, is achieved by the fact that in the aggregate compartment on the bottom of the casing is set partitions, and on the inner side which does not cover set the return walls, when this channel for the passage of air formed by the said walls, the bottom of the case and the inner surface of the cover aggregate cover.

In a variant of the invention the specified technical result is achieved in that the vacuum cleaner includes a housing holds the separating element with through-holes, forming a compartment with a lid having outlet openings, and compartment box with lid that has an input socket, pre-filter, overlapping holes of the separation element mounted in the aggregate compartment damper air suction unit with input and output holes and made in the aggregate compartment channel for the passage of air from the outlet air suction unit to the outlet openings of the cover aggregate cover, and in the aggregate compartment on the bottom of the casing is set partitions, resting their inner ends the surface of the cover aggregate cover, with a channel for passage of air formed by the said walls, the bottom of the case and the inner surface of the cover aggregate cover.

In another embodiment, the cleaner includes a housing holds the separating element with through-holes, forming a compartment with a lid having outlet openings, and a compartment piles is mica with lid, having input socket, pre-filter, overlapping holes of the separation element mounted in the aggregate compartment damper air suction unit with input and output holes and made in the aggregate compartment channel for the passage of air from the outlet air suction unit to the outlet openings of the cover aggregate cover, and in the aggregate compartment on the inner surface of its cover installed partitions, resting his butt on the bottom of the case, with a channel for passage of air formed by the said walls, the bottom of the case and the inner surface of the cover aggregate cover.

In the housing 1 of the vacuum cleaner has air suction unit 2 having an inlet 3 and the outlet 4. In the housing 1 is placed a separator element 5, separating the compartment dust collector 6 and the compartment 7. The separating element 5 is designed as a wall. In the separation element 5 opposite the inlet 3 air suction unit 2 with holes 8, blocked pre-filter 9. Compartment 7 is closed by a cover 10 having outlet openings 11. In the aggregate compartment 7 is made of walls 12 and in the cover aggregate cover 10 is made of the response of the walls 13 forming with the walls of the aggregate compartment 11 channel for the passage of air 14 from the output of the air suction holes 4 of the unit 2 to the outlet openings 11 of the cover aggregate cover 10. Outlet openings of the cover aggregate cover 11 is blocked exhaust filter 15. Phi is Tr 15 is closed by a cover 16, having exhaust openings 17. Compartment dust collector 6 is closed by a cover 18 which is located inlet pipe 19. In a particular implementation of cleaner air suction unit 2 installed using shock absorbers front 20 and rear 21. Front shock absorber 20 seals the channel for air passage 14. In addition, in the aggregate compartment 7 has a mechanism for winding the cord 22 with power cord 23.

The cleaner works as follows.

When you enable air suction unit 2 in the compartment dust collector 6 is formed a vacuum and air is sucked through the inlet 19 in the cover of the dust collection unit 18 in the compartment dust collector 6, and then passes through a preliminary filter 9, the holes 8 of the separating element 5 and is drawn into the inlet of the 3 air suction unit 2, which emits the air through the outlet 4 into the channel for air passage 14. The air on channel 14 extends through the holes 11 of the cover aggregate cover 10, the exhaust filter 15 and the exhaust holes 17 of the filter cover 16.

In the proposed vacuum channel for the passage of air arranged partitions its housing and cover aggregate cover and bottom housing and the top part of the cover. While in the claimed vacuum cleaner kinematic and volume loss of the air flow does not exceed the losses in the prototype, so the AK pathway and through cross-section for air flow there and there are the same. Organization channel for the passage of air baffles and shell elements and cover aggregate cover allows to reduce the dimensions of the vacuum cleaner, its mass and due to the reduction of material consumption to reduce the cost of products (in mass production, the share of materials in the cost is ~70%). The proposed vacuum cleaner allows you to reduce the height of 8 mm, a mass of 6.5 kg to 5.4 kg, the cost with ~5000 rubles. up to ~4280 RUB the calculation of the cost reductions made under the assumption that the share of materials in cost is ~70% and ceteris paribus. Besides reducing the overall mass with preservation of other consumer properties leads to facilitate the use of the product.

Typically, the vacuum cleaner housing and cover aggregate cover are made from thermoplastic materials by injection molding, so the execution of the partitions in these parts to form a cavity for accommodation air suction unit is not technically challenging.
