Description

The present invention relates to household appliances, and more particularly to vacuum cleaners with a water filter.

Known Vacuum Cleaner Designs according to U.S. Pat. 2886127, 07.07.1960. No. 295553 and No. 02 of 1987; 4,640,697 patents.

According to the patents, the structures are characterized by the fact that during cleaning, debris and dust remain in the water, and clean, healthy air is blown out of the pump.

As an analogue, the vacuum cleaner design according to patent no. 4640697, wherein a fluid is used for air filtration.

The main disadvantage of this design is that the unit has two fans, one for cooling the engine and the other for backpressure preventing water from entering the compressor while the engine is running.

When using a backpressure fan, the construction of the unit becomes complicated and at the same time requires more engine power to obtain the required vacuum.

The removal of air for cooling the engine from the center of the housing is also a drawback, since the housing needs to be made of two parts to produce openings - slits, which complicates the construction ii 'increases in cost.

There are no guides at the front of the unit for better airflow from the lower housing, and the cleaning efficiency depends on the amount of air passing through.

The object of the present invention is to simplify the design and reduce energy loss.

The proposed vacuum cleaner design does not have the aforementioned drawbacks in both the air intake assembly and the pump itself.

According to the present invention, the construction of a vacuum cleaner comprises: a special unit with a fan for cooling the engine; a separator for separating dirt from the air stream; continuous outer casing; top cover with baffle, pull-out handle with switch;

two internal housings; base with ring at the back and bottom housing with spherical cover.

The bottom housing cover has an opening through which the separator sits. The bottom housing may be integral with a spherical cap with raised edges corresponding to the shape of a vacuum cleaner.

when the vacuum cleaner is turned on, a vacuum is created in the lower housing through the separator slits. Using a flexible hose, the debris is sucked into the lower casing with water through a hole in the lower housing, where the debris gets wet and stays in the water, and fine and light airborne dust is drawn into the separator slots. Because the separator slits are flat and have walls of appropriate thickness (the width and thickness of the slits are calculated, particles cannot enter the separator because, under centrifugal force, they are pushed back from the separator walls to the lower housing with water. the outer cover of the bearing cap ii 'assembly and the other part of the air flow into the gap between the baffle plate and the separator holder. Further, through the side opening of the bracket, it enters the cavity between the bracket and the outer housing, and then through the crevices between the outer housing and the upper contour of the lower housing, enters the environment.

DETAILED DESCRIPTION OF THE WATER FILTER - a longitudinal section of the vacuum cleaner and assembly according to the present invention.

picture - air intake cover.

picture - lower body with spherical cover.

The water filter vacuum cleaner consists of a bottom housing 1 with a hole 40 for connecting a flexible hose and a spherical cap 2; base 3; continuous outer housing 4; unit 6 (motor with two-stage compressor and separator 7); the two inner housings 5, 11 and the cap 16.

The assembly unit 6 is mounted on a base 3 by means of two dampers 8, 9, screwed 10 and secured in an upright position by an inner housing 5. The housing 5 has a hole 17 for air passage from cavity 35 to cavity 18. , through which the assembly lid 12 is pierced through a hole. A rubber seal 13 is provided between the assembly cover 12 and the housing 11, which seals the cavity 39 and quenches the vibration of the assembly cover.

The housing 11 in the lower portion has a flap 22 and a plurality of slots 14 for the output of engine cooling air from cavity 39 to cavity 15. Folding 22 is for forming two cavities 16 and 18, the first between the outer 4 and inner 11 bodies, the second between outer 4 and inner 5 bodies.

The housing 11 is mounted on the housing 5 and fastened with screws. On the top of the housing 11, an outer housing 4 and a cap 16 are fitted with a pull-out handle ii 'with a switch 37, which are fixed by screws 46.

There is an air gap 25 between the cap 16 and the outer housing 4 The space 30 between the cap 16 and the housing 4 is divided by a barrier 30 into two parts: a pressure cavity 24 and a vacuum 31. The cavity 31 is for cooling the engine and opening 25 into the environment.

In the upper part of the outer housing 4 there are a number of openings 23 for the air inlet and the outlet into the chamber '24.

The assembled upper motor housing is positioned on the lower housing such that the separator enters through the spherical cap hole into the lower housing, and the spherical cap 2 aperture edges rest on a rubber gasket 9. .

If the lower body is integral with a spherical cover, it is only an intermediate 9. The base 3 has a cylindrical bow at the lower part

- an extension 21 which prevents damage to the separator by removing the upper part of the pump from the lower housing. The extension of the base 3 always has an air gap with respect to the cap 2. The composite lower housing is connected to the upper by external clips.

The air suction assembly consists of the following units — an electric motor, a special compressor, a separator, and an engine cooling fan.

At the front of the assembly are two caps: a cap 26 on which a separator 27 is mounted to prevent water from entering the compressor of the assembly 6 through the crevices between the holder 28 and the inner side of the cap 26 firmly attached to the cap of the compressor 29; the cap 29 is for mounting the third bearing (rubber sleeve) and is also an airflow guide, which is turbinated by slots 46 (Fig. 2) and enters through an opening 42 (Fig. 1) in the center of the compressor cap into zone 32 , into the deflector 43, the second turbine 32, then the slit 34 and into the cavity 35.

There are bumps on the surface of the cover 29 to improve the passage of the air flow created by the compressor into the crevices 46 (Fig. 2) and to reduce the air flow loss.

The bracket 28 (Fig. 1) is mounted on the axis of the assembly and is fastened by a nut 38. The bracket 28 is cylindrical on one side for inserting the separator 7 and on the other is provided with a flap which includes a flap. In the flat part of the separator there are a number of windows 41 for the passage of air through the slots by pumping air from the lower housing. The bracket 28 rotates with the separator 7 and has an air gap between the hinged cylindrical portion of the cap 26.

The separator 7 is placed through its central hole on the axis of the assembly and its outer part with its rim is resting on the cylindrical part of the holder 28.

The separator is a tapered sleeve with slits of corresponding size on the outer surface.

The bottom housing 48 (Fig. 3) and the cover 49 are of a solid construction, without having to be removed and cleaned for cleaning, and the cabinet itself is easily handled by the upper edges, which are always clean.

In the case of a solid housing with a spherical cover, the clamps connecting the upper and lower housing can be mounted on the cylindrical part 21 of the base 3 (Fig. 1), which rests on the rubber gasket 52 (Fig. 3).

The vacuum cleaner with water filter (Fig. 1) operates as follows: when the motor of unit 6 is turned on, the compressor turbines 32, fan 33 and separator 7 rotate.

As the turbines 32 rotate, the lower casing creates air depletion which, through a flexible hose connected to the orifice 40, draws in air with the debris and the resulting pressure rotating the separator 7 dampens the debris in the lower casing. Wet debris falls to the bottom of the lower housing, and very fine dust particles in a slurry state are exposed to the exhaust air and drawn into the flat slits of the separator 7.

Centrifugal force ii 'is exerted on the outer part of the rotating separator by the fine dust particles trapped on the separator and applied back to the lower cusp ii' by the applied centrifugal forces so that they cannot enter the separator. As a result, only air enters the separator 7. After this, clean air passes through the opening of the holder 28 into the opening ii 'of the baffle plate 27' and enters the cavity formed between the baffle 27 and the cap 29. Since the holes in the baffle plate 27 are smaller than the openings in the cap 29, the part passes through the resulting gap between the rotating bracket 28 and the separator plate and creates back pressure, which prevents water from entering the compressor of the unit through the slits.

The air passes through slots 46 (Fig. 2) of the cap 29, further through a hole 42 (Fig. 1) in the compressor cap, and enters the first turbine 32 into the deflector 43, and from there to the vent 42 and the second turbine 32 and discharges. through the slit 34 in the outer compressor housing into the cavity 35, thence through the opening 17 into the cavity 18. From the cavity 18 through the slit 19, the clean air from the base and housing 4 is discharged into the environment at a lower airflow rate.

At the same time, the fan 33 begins to pump air through the slit 36 into the cavity 31 and cools the engine. After the engine has cooled, air enters cavity 39 and further into cavity 15 through slots 14 of housing 11. Air from cavity 15 enters cavity 24 in cap 16 and passes through opening 24 in upper portion 4 of housing 4 through slit 25.

This design solution made it possible to simplify the design of the vacuum cleaner, eliminating the additional fan needed to create backpressure that prevents water from entering the compressor. The separator 27 is used instead of a fan.
