DE202006018995U1 - Under-panel device for sucking up fine dust has cut-out in which a filter can be inserted so as to be flush fitting, bottom opening via which fan sucks air and vents air out via vent holes on outlet side of housing - Google Patents

Abstract

The device consists of a housing (3), a filter (5) and a radial fan with a drive. The upper side of the device has a cut-out (4) in which a filter can be inserted so as to be flush fitting and in whose bottom an opening (2) is cut out via which a fan sucks air and vents the air out via vent holes (1) on the outlet side of the housing.

Description

The The invention relates to a lower table device for sucking fine Dust.

Fine dusts arise on diverse Way, but especially in the cosmetic processing of fingernails through Filing. For example, to prevent their absorption via the respiratory system, come so-called under-table suction devices used. In so far known design These are devices that are fixed to the bottom attached to the treatment table, and the contaminated air over a Suck recess in the worktop and with the help of a fan downstream filter cleaned below the work surface to the Blow out the environment.

there come so-called axial fans used in which the individual rotor blades a centrally located spindle are arranged so that the axis of rotation of the rotor runs parallel (axially) to the air flow and either directly via a Electric motor, whose shaft reaches into the rotor, or over one Riehmenantrieb is set in rotational motion.

Around not to affect the suction power of the device, is in a known embodiment Filter brought into the air flow on the outlet side, so the Fan downstream. The movable rotor is characterized by a so-called. Ventilation grille, which usually flush with the worktop of the nail table, protected.

Of the Disadvantage of known suction devices consists on the one hand in their relatively large height at undertable mounting, so that on one side, the legroom on the other side, so the clear height of intake to Soil, in direct proportion affected.

To the Another disadvantage is that the filter is downstream of the fan is, so through the ventilation grille Guessed small parts are detected directly by the rotor of the fan and damaged or because of their hardness to damage can lead to moving parts of the device. It also happens a pollution of device, fan and motor housing up the contaminated air hits the filter.

One Another disadvantage is that the anglogenic air either without diversion, in direct extension must be blown down to the suction direction and thereby to unpleasant drafts on the legs leads or be redirected must, what an additional Design effort means.

adversely are the low pressure and the high operating noise of the Axial fans.

Of the Disadvantage of a riehmengetriebenen rotor blade with indirect drive lies above all in its constructional overhead and increased wear. fan blade and engine are to be stored separately and secured against each other and the Riehmen to drive subject to wear.

Of the Invention is based on the object, a Untertischabsaugvorrichtung to be provided by a recess in the table top the air sucks, has a low height, quiet operating noise simultaneously provides high pressure and their moving parts so protected, that neither a hazard another damage, contamination by foreign bodies or dust particles is still possible, should this through the ventilation grille devices. The device should then be low in wear and lateral and / or a person with a negative outlook from the point of view of a person working at the table, further referred to as the rear outlet direction.

According to the invention, the solution of the problem is achieved by a mounted below the worktop suction, so-called. Untertischabsaugvorrichtung consisting of a housing ( 3 ), which consists for example of polystyrene, polyetylene (PE), Polyvenylclorid (PVC) and other plastics, of acrylic, various metals, such as galvanized or non-galvanized sheet metal, aluminum or wood. Also proposed are combinations of the individual materials.

The device is mounted below the worktop, has on its top a recess ( 4 ) into which a filter is flush ( 5 ) can be inserted, in a preferred embodiment, a Z-filter with plastic frame class F5-F9. In the bottom of the recess ( 4 ) there is an opening ( 2 ), via which a radial fan with scar drive sucks in air and on the outlet side via the ventilation holes ( 1 ) blows laterally and / or rear, in a further embodiment, the outlet can be extended by an air duct.

Of the proposed radial runners with scar drive indicates high pressure at the same time low operating noise and low height. The pre-built filter makes even the smallest objects and equipment as well as, depending on the filter class, the finest dusts from the moving and kept immovable parts of the device. The side and / or blown back air is cleaned in this respect.

Embodiment:

Extractor for under-counter mounting, consisting of a carcass ( 3 ) with a recess for receiving a filter insertable, an opening in the recess for sucking air through a radial scarf drive and side and / or rear vent holes on the outlet side.

The Device may be made of plastic such as polyethylene, for example, Polystyrene, polyvinyl chloride but also acrylic, metal, such as aluminum, Sheet metal etc. or wood.

In a preferred embodiment, the suction power of the radial scaler with scar drive via a control or regulation ( 6 ), for example transformer dimmers, as desired.

In Another preferred embodiment is at the outlet opening a Air duct connected as an extension.

Claims (5)

Sub-table device for extracting fine dusts, consisting of a housing ( 3 ), a filter, a Radialventialator with scar drive, characterized in that in the top of the device ( 3 ) a recess ( 4 ), into which flush a filter ( 5 ) and in the bottom of an opening ( 2 ), via which a radial fan with scar drive sucks in air and on the outlet side of the housing ( 3 ) via ventilation holes ( 1 ) discharges laterally. As claim 1, characterized in that the housing ( 3 ) Made of plastic, such as polystyrene, polyethylene, polyvinyl chloride, acrylic, metal or wood is bildbar. As claim 1, characterized in that the Rotation speed of the centrifugal fan via a Trafodimmer adjustable is.
