Description

DESCRIPTION

HYDROCYCLONIC FILTER FOR DRY AND WET VACUUM CLEANER

TECHNIQUE SECTOR

The present invention is based on a hydrocidonic filter for a vacuum cleaner for domestic use with a water tank for cleaning dry or wet floors with liquids, which allows the collection of suspended solids aspirated. Thus, by means of a circular movement of the water contained in the tank, the sucked solids are removed and grouped concentrically in a central settling vessel or bucket at the end of the vacuum cleaner's function.

It can be used in automatic, semi-automatic or manual vacuum cleaners for cleaning surfaces, whether electric or with rechargeable batteries.

BACKGROUND OF THE INVENTION

At present, multiple-use suction devices are widely known, which allow, for example, the simultaneous collection of substances in solid and liquid state.

This type of product has a container or dirt tank where a suction tube is connected to collect dirt, in solid or liquid state. Said dirt is absorbed into the tank or container using the vacuum generated by an electric suction motor, generally located in the upper part of said tank and which serves as a cover to generate the necessary depression for absorption.

Conventionally, these vacuum cleaners indifferently aspirate solids and liquids, depositing said materials in the same container without making any distinction. That is to say, there is no filtering between the particles in the liquid state and those in the solid state, forming a mixture of both types of waste inside the receptacle of the apparatus. This mixture can be homogeneous or heterogeneous in depending on the nature of the items collected

On the other hand, it is widely known in the state of the art of this category of products the existence of a filter located in the upper part of the product whose function is to filter the dust particles that have been sucked through the tube. Said filter is widely known for use and is widely extended, not only in liquid and solid vacuum cleaners, but also as a general rule in any type of suction cleaning device. Normally, this filter should not get wet, unless such an option has been considered in its design and as long as its material is resistant to water.

In the European patent EP0921748B1 GORE & ASS (1999) we can see a vacuum cleaner capable of collecting both liquid and solid material, which is made up of a tank, a suction unit, a suction tube and an air outlet. This vacuum cleaner has a filter cartridge in the suction unit that is in contact with the liquid material and when the filter membrane is completely covered by the liquid material the suction unit would turn off thus avoiding the overflow of the liquid material from the tank. . This document protects the filter from working with liquid material, but does not affect solid material.

Additionally, the European document EP1000579A2 SHOP VAC CORP (2000) describes a vacuum cleaner having a double filter assembly, comprising: a filter support; a primary filter arranged on the filter holder; a secondary filter arranged downstream of the primary filter; and a valve to prevent liquid from coming into contact with the secondary filter. In this case, two filters are presented, one to control the level of the liquid material and another, which must not come into contact with the liquid material, which will serve as protection against the solid material found in the aspirated air.

In relation to the above, it is reflected that in the state of the art the use of filters for vacuum cleaners of liquid and solid material capable of performing a separation between both materials is not addressed, which would thus allow the improvement of cleaning, maintenance and evacuation of the deposit dirt.

EXPLANATION OF THE INVENTION

The present invention has a vacuum cleaner capable of collecting solid and liquid material that contains, at least, the following necessary technical elements:

- A top cover;

- A suction motor;

- A power cord or battery;

- A dirt tank for vacuumed material;

- A filter for cleaning the aspirated air;

- A lower base;

- Wheels or conveyor wheels;

- A suction tube.

The technical problem to be solved with the present invention focuses on the lack of solutions that allow the separation between the liquid material and the solid material sucked by domestic or industrial vacuum cleaners.

This invention intends to solve the previously stated problem present in the apparatus belonging to the state of the art, and in the means currently known. The components of this innovation consist of a circular-shaped dish with a certain inclination towards the interior, a concentric beaker with the previous dish, a mesh, mesh supports, support ropes and an upper support. The elements that make up the invention are preferably removable from the assembly. This facilitates the maintenance and repair of the invention, since, in case of breakage, it is possible to change the damaged component instead of the entire complete system.

The material used for the components of the plate, the central cup or cube, the mesh support and the upper support are preferably made of plastic. The mesh will preferably have a porosity of 1 mm width for the interstitial holes or mesh size between them. In this way, the passage of water is allowed, but not the solid components that have been sucked by the vacuum cleaner.

In addition, the support ropes must be capable of resisting a tensile force that would be required to lift the lid with the dirt tank filled with the entire volume of liquid and solid material.

The components described above and that form part of the invention of the filter that is being considered are located in the dirt storage area of the aspirated material which, in a preferred embodiment, will have a cylindrical shape, and may have different radii. Being directly connected to the head or upper cover of the vacuum cleaner in its internal part.

The functionality of the filter is as follows: The liquid or solid material is introduced into the dirt deposit through the suction tube that has previously sucked it. The ejector mouth of the suction tube in the dirt deposit will be located between the base plate, normally circular, and the mesh proposed in the invention. The discharge of liquid or solid materials sucked into the dirt tank are dumped in such a way that the sucked air, in which the sucked substances are found, forms a whirlpool inside the dirt tank when it is expelled at the outer end of the dirt tank. the base of said dirt deposit propelled by its own suction force. By forming a vortex inside the tank, the solid state materials move concentrically towards the central area of this dirt tank where the cyclonic filter has been inserted. Depending on the density of the solid materials, they will be deposited at the bottom of the tank or will remain floating in the liquid material. If the solid materials are denser than water, then they will fall to the bottom of the container where they will be introduced into the central beaker or bucket that is part of the filter. If, on the contrary, they are less dense than the liquid material, they will remain floating in it. In either of the two cases, the materials in the solid state will remain retained within the filter presented by this invention, while the material in the liquid state can come out of it.

Once the vacuum cleaner has finished working, the material that is located inside the vacuum cleaner tank stabilizes, that is, the eddy that had formed when introducing the sucked air with the solid or liquid materials ends. In this moment the liquid material would be distributed throughout the tank, having the possibility of entering or leaving the filter. And so, the solid material that is denser than the liquid material would settle and settle in the beaker. Just as, the solid material less dense than the liquid material would be floating, but located inside the filter. In this way, a system capable of separating the solid materials from the liquid materials is obtained, thus favoring the cleaning of the dirt deposit by the user, since the solid materials have been screened from the liquid ones.

To clean the inside of the dirt tank that contains the filter, once the suction tasks have been completed, two situations are contemplated: First, the user must decide whether to first remove the liquid material and then the solid material or vice versa. In the event that the liquid material is to be removed first, an outlet conduit for liquid material must be located at the base of the vacuum cleaner. In this way, the vacuum cleaner is emptied of liquid content and the solid material would remain located inside the filter itself. If, on the other hand, you want to proceed with the cleaning in the opposite way to that mentioned above, when removing the cover of the vacuum cleaner, the filter that is connected to the upper cover of the vacuum cleaner, would allow that, when removing the cover with an upward manual movement , the solid material would come out together with the filter at the top while the liquid material would remain inside the dirt tank itself.
