Abstract

FIELD: vacuum cleaning equipment for removing dust out of living rooms.

SUBSTANCE: vacuum cleaner includes turtle like housing divided in its mean portion by means of fluid-tight partition by two separate cavities. In front cavity there is filter for primary air cleaning; such filter includes bushing with metallic grid. In lower rear part of housing bottom with openings is mounted. Nozzles are mounted in said openings and their lower ends are immersed into water poured in pan secured to lower part of housing having labyrinth for removing air-laden superfine water drops. Air passing through vacuum cleaner is cleaned three times. Primary cleaning is realized before blower by means of metallic grid and bushing. Secondary cleaning is realized after blower by means of nozzles that divide air flow by fine streams passing through water layer in the form of small-volume bubbles. Third stage of cleaning by removing superfine water drops is realized when air flows through labyrinth.

EFFECT: enhanced degree of cleaning air passing through vacuum cleaner, improved comfort of using vacuum cleaner.

Description

The invention relates to household appliances and is intended for cleaning residential premises from dust.

Currently, domestic and foreign vacuum cleaners with fabric and paper filters are used, which have a number of significant drawbacks:

1. If the filters (dust bag and paper filters) become dirty, the suction capacity of the vacuum cleaner decreases.

2. After each use of the vacuum cleaner, it becomes necessary to shake out the bag of the dust bag with access to the street, which creates inconvenience in operation.

The closest analogue of the claimed vacuum cleaner is a known vacuum cleaner containing a housing divided in the middle part by a partition into two independent volumes, a supercharger with an electric motor and a primary filter for air purification located in the front volume, having a glass (RU 2240027 C1, 11/20/2004).

In this vacuum cleaner, the above disadvantages are eliminated due to the use of water as a filter medium with the simplicity and ease of maintenance of the vacuum cleaner.

The aim of the invention is a more complete cleaning of the air passing through the vacuum cleaner, simplicity and ease of use.

This goal is in a vacuum cleaner containing a tortoise-shaped case, in the middle part divided by a sealed partition dividing the case into two independent volumes, a primary air purification filter containing a glass with a metal mesh is placed in the front volume, the bottom with holes is fixed in the back of the case in the lower part in which nozzles are fixed, the lower ends immersed in water poured into a pan fixed in the lower part of the housing containing a labyrinth for cleaning from the smallest drops of water in the air is achieved the fact that the air passing through the vacuum cleaner is subjected to three times cleaning, the primary occurs before the blower using a metal mesh and a glass, the second degree of cleaning occurs after the blower using nozzles dividing the air stream into small jets, in the form of small volume bubbles passing through a layer of water , and the third degree of air purification from the smallest drops of water occurs when air passes through a maze.

The proposed vacuum cleaner is schematically shown in the drawings, where Fig. 1 shows a longitudinal section of a vacuum cleaner body; figure 2 shows a longitudinal section of a pallet; figure 3 shows the pallet, a top view; figure 4 shows a longitudinal section of the nozzle.

The proposed vacuum cleaner contains a tortoise-shaped body 1 (Fig. 1), in the middle part separated by an airtight partition 2, on which a supercharger 3 is mounted, which is rotationally driven by an electric motor 4.

In the front of the housing there is a glass 5 (Fig. 1), closed on top with a metal mesh 6, with its central hole mounted on the suction pipe 7, mounted in a removable cover 8, containing a fitting 9 for attaching the sleeve of the dust collector. In the lower part of the body, a bottom 10 is fixed with holes in which the nozzles 11 are fixed, the lower ends immersed in water poured to a certain level 12 into the cup of the pallet 13 fixed in the lower part of the housing 1. The pallet is a double-sided cup containing drain channels 15 and filler neck 16; to the bottom 10 (figure 1) in the lower part is attached a skirt 14 (figure 1), dividing the space between the sides of the pallet and forming a labyrinth for air to escape from the pallet. Nozzles 11 (figure 4) are conical tubes, narrowly fixed in the holes of the bottom, in the lower wide part there are a number of lateral 17 and one central hole 18 (figure 4).

The proposed vacuum cleaner works as follows:

During the operation of the supercharger, a vacuum is generated in the volume up to the supercharger. The air from the dust collector rushes along the sleeve into the suction pipe 4 (Fig. 1), when leaving the pipe, the air changes its direction by 180 degrees, rises, passes through the strainer and fills the volume to the supercharger. Heavy particles with speed fall to the bottom of the glass, and light bulk particles settle on the grid. Thus, the primary air purification to the supercharger occurs. Having passed the supercharger, the air flow using nozzles is divided into many small jets. After passing through the cone nozzles, the air velocity decreases, which reduces the seething layer of water in the pan. At the exit from the nozzle by means of holes in the nozzle, the air stream is additionally divided into smaller jets and passes through a layer of water in the form of small bubbles. Upon reaching the surface, the bubbles burst and dust particles dissolve in water. Thus, secondary fine cleaning of the air passing through the vacuum cleaner occurs. The air cleaned from dust through the maze formed by the sides of the pallet and the skirt 14, comes out. The smallest drops of water in the air, passing the maze, settle on the walls of the labyrinth and merge through channels 15 into a pan tray. Thus, the air is cleaned of moisture.
