The invention relates to vacuum cleaners of the so-called "detergent type, i.e. able to absorb liquids.

Vacuum cleaners are well-known for their ability to absorb liquids used for cleaning spills. In addition, these vacuums can be adapted for the cleaning of floors, such as carpet, by coating the liquid on the surface to be cleaned and removed by suction. One well-known type of such a vacuum cleaner includes a housing in the form of capacity or containing vessel in which contaminants, including liquid can be sucked through the suction hose connected to it. The motor and fan made with the possibility of suction of air from the tank and lowering the pressure therein so that the air and carry out the liquid or other contaminants can be absorbed into the container through the sleeve. Outlet from the tank, passing to the fan, is located in its upper part, and, usually, in that the discharge channel is the float valve so that when the container is filled, the outlet channel is closed, thus preventing the absorption of fluid in the fan and leaving the vacuum cleaner through the exhaust channel of the fan. One known type of such a float valve includes a casing, passing down into the tank from the e exhaust channel, containing the float element, which when lling POPs up inside the casing until then, until it reaches the outlet and will not block it.

To ensure the effective suction of liquids vacuum cleaners usually contain relatively powerful motors and fans, and the air flow rate through the fan, capacity, suction hose and any cleaning attachment or fitting, which are located at the free end of the sleeve, is high. Liquid, carry out such air flow, must be separated from the air stream, so that it remains inside the tank and not out through the fan, even when the container is not filled. It is known that the suction hose can be connected to the tank through the fitting, which includes a cranked tube, so that any carry out liquid is separated from the air stream as a result of changing flow direction and, hence, reduction of the flow velocity at the entrance to the tank. However, such a device on the intake hole in a container includes the use of additional and more complex element, which may be insufficient to block, if absorbed separate large solid objects.

Therefore, the General purpose of the present invention is to improve the device is VA, in which liquid is carried away by the air flow device remains in the container.

Thus, in accordance with one aspect of the present invention generated steam cleaners containing tank having inlet for the suction air stream and the exhaust port leading to the fan, for creating a suction force, and the site of the float valve containing casing and the float element that moves relative to the shell to ensure the closing of the outlet, with the inlet opening directs the intake air flow for colliding with part of the casing, while the casing has a hole leading to the outlet, which is a part of the casing, facing away from the inlet, and the casing further comprises deflecting means for deflection hits contaminant particles from the hole.

In accordance with another aspect of the present invention, the set of node float valve for installation in a detergent cleaner containing casing having a discharge outlet, or made interoperable with the outlet, the float element is able to move relative to the casing to ensure the closure of the outlet opening of the reflective surface on the outer side of the casing facing the first direction, the hole on the outside with the Auron casing, leading to the outlet, the opening facing in a direction generally opposite to the direction in which the facing reflective surface, and deflecting means for deflection of polluting particles from the reflective surface away from the hole in the casing.

The casing of the host float valve may be largely circular in cross-section constant or non-constant diameter or may have any other appropriate shape. The reflective surface may contain about half the periphery of the casing, and a hole leading to the interior of the casing and thence to the outer hole can contain about half of its opposite periphery. The deflecting means may include a wall, passing outward from the outer surface of the casing between the hole and a reflective surface.

The capacity of the vacuum cleaner may be essentially circular or other shape in top view, and the site of the float valve passes down into the container from a position in the center or near the center of the housing that is installed in the upper part of the tank casing that contains the motor and fan). In this case, the discharge opening can be on the upper end of the casing, or formed in the casing, or part of the body of the vacuum cleaner, which connects the casing. The inlet opening into the container may be formed in its accessories is rinoy the wall at an appropriate distance above the bottom part of the vessel and pass in the radial direction to access the site of the float valve.

In accordance with this configuration, the casing and other elements of the vacuum cleaner deflecting means containing a rib or wall, passing outward from the outer surface of the casing, can be carried down from the upper end of the casing at its opposite sides, and opposite side edges can converge to intersect with each other at the bottom of the casing on its side facing the inlet opening (front holes). Thus, a wall or the edge can, in General, to have a basically C-shaped. The hole in the casing may be formed in the upper part of the casing above the maximum liquid level, which can be expected in it) on his side, facing away from the inlet.

The float element may be spherical or cylindrical, guided to move up and down within the casing by means of elements, for example, passing inside edges that are oriented up and down inside the casing.

Although the scope of the present invention includes deflecting means formed as a separate element or elements that are attached or connected to the casing of the host float valve, preferably, the deflecting tool was designed as one piece with the casing, for example, in the form of an element obtained by molding plastic.

The present image is eenie will be described as an example with reference to the accompanying drawings, on which:

figure 1 is a side view in partial section of a vacuum cleaner in accordance with the present invention;

figure 2 is a perspective view with partial cut vacuum cleaner parts;

3 and 4, a side view and front view, respectively, of the casing of the float valve of the vacuum cleaner; and

5 is a perspective view of a shroud.

Figures 1 and 2 illustrate "detergent type cleaner in accordance with the present invention. The vacuum cleaner includes a tank 10, which has a round shape in top view, having a peripheral wall 12, which is slightly narrowed from top to bottom, with the bottom wall, which has a complex shape, having a series of peripheral passing upward and radially inward of the notches, two of which are denoted by reference positions 14, 16, which are relevant to the wheels, providing the movement of the vacuum cleaner on a floor surface. The upper part of the vessel 10 is closed by a housing, generally indicated by the reference position 20.

The housing 20 is held up from the top of the tank 10, and installed inside the motor and fan site, through which air can be sucked from the interior of the tank 10, and which cause the air to be sucked into the container through the inlet opening 22 in the peripheral wall 12 of the tank. The inlet opening 22 contains the fitting 24 for bayonet connection of suction hoses (not the rendered). Such education inlet openings in the peripheral wall of the capacity of the vacuum cleaner and the location of the motor and fan in the upper part of the housing of the vacuum cleaner is well known and therefore will not be described in more detail in this document. Facing the interior of the tank 10, the housing 20 includes an exhaust hole that leads to the fan and from the fan outlet to intake air through the tank by means of the fan leads into the environment.

The site of the float valve, wholly indicated with the reference position 30, passes downwards in the vessel 10 from the center of the housing 20. The site of the float valve includes a casing, the configuration of which is shown in more detail in figure 3-5. The casing is entirely marked reference position 32, is a narrowing down partially conical configuration with a lateral flange 34 on the upper end. The flange 34 includes three spaced along the circumference at a distance from each other holes, one of which is denoted by the reference position 36 for insertion of fasteners, such as bolts or screws by which the casing may be attached to the bottom surface of the housing 20 around the exhaust hole in it. The casing contains six located at a distance from each other along the circumference passing radially inward direction is the corresponding edges denoted by the reference position 38, which guide the float element (not shown) to move up and down inside the casing 32. The float element may be spherical or perhaps cylindrical or may have a different shape and is configured to contact and close the outlet when the liquid level in the tank reaches the permissible maximum, thus preventing further absorption of air from the interior of the tank, the fan of the vacuum cleaner and, thus, additional liquid intake. Such a device in a washing vacuum cleaners are well known.

The housing 32 contains on one side the upper part of the reflective surface 40 that faces the inlet opening 22 into the container. The reflective surface is limited deflecting element 42 in the form of a wall, which runs in a radial direction outward from the outer surface of the casing 32. Opposite ends 44, 46 of the deflecting element 42 are held down by the peripheral flange 34 at the top of the casing 32, and then the appropriate parts of the deflecting element bent at 48, 50 as long as they do not pass along the circumference of the casing and will not intersect with each other at 52. Thus, the deflecting element, in General, usually has a C - or U-shaped.

On the opposite side of the casing 32 reflected from the positive surface of the casing 40 includes a hole 54, leading into the inner casing, and the hole is divided into three parts by two ribs 38. They provide access of air to the interior of casing 32, whence it is drawn through the outlet into the fan and then released into the environment, provided that the liquid level inside the tank 10 is not sufficient to float the element has risen high enough inside the casing 32 for closing the outlet opening.

The reflective surface 40 of the casing facing the inlet opening 22. If the liquid is captured in the intake air flow incoming into the container through the inlet opening 22, it is facing surface 40, which causes the liquid droplets to separate from the air flow. This separated liquid flows down under the action of gravity on the surface 40 directed deflecting element 42 in the lower portion 52 of the element, and falls into the tank. Parts 44, 46 of the deflecting element to keep the coolant from the suction intake air flow through the opening 54 for the passage in the outlet and the fan.

It is obvious that modifications relative to the variant illustrated implementation of the present invention without departing from the basic scope of the present invention. For example, the capacity of the vacuum cleaner may have a different Faure is, non-circular shape in top view, as well as the site of the float valve, and the latter does not necessarily have to be in the center of the vessel, but instead may be located closer to one of the vessel wall than to the other.
