Definitions

  • the invention relates to a table device with a table and with at least one exhaust air opening arranged in a table surface of the table, the exhaust air opening being flow-connected to a ventilation system, the ventilation system having a suction device for sucking off ambient air through the exhaust air opening, and the ventilation system having a filter device for filtration extracted ambient air.
  • Table devices for extracting the ambient air from the table are known from practice, for example in the form of a wood dust extraction system or a soldering site extraction system. Common to all of the configurations is that a work area on or above the table surface can be contaminated with dust, dirt or other deposits while working, with one task of the various suction devices being to intercept and remove the various contaminations early and continuously in the work process.
  • the extraction systems are often designed to be mobile and independent of the table in order to enable flexible use.
  • suction devices are also known from practice that are connected and integrated on or with the table as a table device.
  • Suction devices are known from practice, especially in medical and pharmaceutical areas, which are stationary in a room and suck off, filter and decontaminate the ambient air or the ambient air of neighboring rooms, so that any possible released by a person into the ambient air and harmful to other people and no harmful germs, bacteria or viruses can be transferred from this person to another person.
  • the table device has an air supply device which is arranged above the table and fixed to the table and has at least one air supply opening, the air supply opening being flow-connected to the ventilation system and the filtered ambient air being able to be blown out in the direction of the table surface of the table via the air supply opening .
  • the ventilation system, the exhaust air opening and the air supply opening can be flow-connected to each other via flexible pipes, air hoses or a pipeline system, all of which are attached to the table.
  • a fan assigned to and comprised by the ventilation system can provide a differential pressure in order to set the filtered ambient air that can be blown out into motion.
  • all of the components according to the invention are integrated in the table device and the table. Not only that the filtered ambient air can be blown out through the work area in the direction of the table surface; Any contaminated or unfiltered ambient air in the work area is also extracted via the exhaust air opening, so that the ventilation system, the air supply device and the exhaust air opening result in a quasi-closed and flow-connected system.
  • the filter device can advantageously have a suspended matter filter class according to EN 1822-1:2009 of H14, particularly advantageously even a filter class of U15, so that a particularly good filter effect of the Ventilation system is achieved with a high degree of separation.
  • the table device has the advantage that the entire ambient air of a room no longer has to be filtered, but only the ambient air surrounding the person who works at the table and whose breath flows into the working area of the table.
  • the exhaust air and/or air intake openings are elongate, with at least the elongate exhaust air opening being arranged on a table edge section of the table running adjacent to at least one table edge, so that the exhaust air between the elongate exhaust air - and/or supply air openings, filtered ambient air that can be blown out forms an air curtain.
  • An air curtain or air curtain then arises regularly if at least the exhaust air opening is elongate, so that the filtered ambient air that can be blown out through the air intake opening can form a laminar air mass flow, which can then act like a curtain for the ambient air contained in the work area.
  • the technical effect of the air curtain is that the ambient air in the work area is decoupled from the ambient air outside the table by means of the air curtain, which acts like a curtain. Mixing of the ambient air masses is significantly reduced by the air curtain, so that the exhaust air opening can extract the ambient air in the work area more effectively and in a more targeted manner.
  • the effect of the air curtain is all the greater, the more the exhaust air opening surrounds the table surface along a circumference - in the most effective case along the entire circumference of the table surface, so that a closed air curtain can form.
  • the exhaust air and/or air intake opening is L-shaped or U-shaped, so that the air curtains enclose a kind of air chamber.
  • a U-shaped exhaust air opening can be formed, for example, by three elongated openings that are arranged in a U-shape in the table edge section of the table that runs adjacent to the at least one table edge.
  • the table device In order to have more freedom when designing the flow conditions of the air curtain, according to a particularly advantageous embodiment of the table device according to the invention, it can be provided that several exhaust air and/or air supply openings are provided, the exhaust air or air supply openings being arranged adjacent to one another, so that the filtered ambient air that can be blown out between the exhaust air and/or air supply openings forms an air curtain.
  • the exhaust air and/or air intake openings can consist of a plurality of openings, which themselves can be configured differently.
  • the several openings can be designed, for example, in the form of points, slots or holes. An air curtain with different aerodynamic properties can be produced with each of these configurations.
  • a cross-sectional area of all exhaust air openings is designed larger than a cross-sectional area of all air intake openings, whereby slightly more contaminated ambient air can always be sucked out of the exhaust air openings than filtered ambient air can be blown out of the air intake openings.
  • each air supply opening is assigned two exhaust air openings, with the exhaust air openings being arranged parallel to one another in the table surface and running along it, with the air supply opening assigned to the exhaust air openings running between the exhaust air openings which are spaced vertically from the associated air supply opening, so that the Exhaust air openings can suck out the contaminated ambient air on both sides of the air curtain.
  • the cross-sectional area of all exhaust air openings is twice as large as the cross-sectional area of all supply air openings. As a result, less contaminated ambient air can escape from the work area, since ambient air outside of the work area always flows in and is also extracted by the exhaust air openings.
  • the suction device associated with the ventilation system is arranged in a workplace container of the table device.
  • the working areas and the tables are often assigned workstation containers that are specifically provided for the respective tables, in which tools or other documents for the people working at the table can be placed and stowed away.
  • the essential components of the ventilation system and the suction device can be accommodated in such workplace containers.
  • the workstation container can be firmly connected to the table or the table equipment so that it cannot be moved.
  • it can also be configured as a commercially available mobile container with castors in an area around the table so that the area around the table can be flexibly adapted to the work situation by the person working there.
  • the arranged above the table and on the table specified supply air device is attached by means of a cross brace above the table.
  • the supply air device can be effectively arranged and positioned above the table surface, it also being possible to produce an air curtain along the full circumference of the table surface.
  • the air supply device arranged above the table has a lighting device with which the table surface of the table can be illuminated.
  • the lighting device can also be effectively combined with the air supply device in one housing, in which case the lighting device can include LEDs, fluorescent tubes or else other energy-saving light sources.
  • the air supply device arranged above the table is height-adjustable in terms of its distance from the table and its table surface, so that the air supply device can be adapted to the work area required by a person above the table surface.
  • the work area above the table surface, in which one person can work can be adapted to the respective person by means of the height-adjustable air supply device
  • the height-adjustable air supply device can also be used aerodynamic properties of the filtered ambient air that can be blown out by the air inlet device can be adjusted, since a distance between the air inlet opening and the air outlet opening can be designed to be adjustable with the height-adjustable air inlet device.
  • the stability of the air curtain can also be adjusted with an elongated exhaust air opening, because as the distance between the air supply opening and the exhaust air opening becomes smaller, any vortices in the filtered ambient air that can be blown out of the air supply device are also reduced, so that the filtered ambient air that can be blown out is largely laminar can flow.
  • the stability of the air curtain can also be adjusted with an elongated exhaust air opening, because as the distance between the air supply opening and the exhaust air opening becomes smaller, any vortices in the filtered ambient air that can be blown out of the air supply device are also reduced, so that the filtered ambient air that can be blown out is largely laminar can flow.
  • the ventilation system detects properties of the filtered ambient air that can be blown out in the direction of the table surface, so that a deviation in the properties outside of a regulated and controllable range can be detected. Recording the properties of the filtered ambient air can be used to monitor the germ load in the filtered ambient air and to adjust the blower assigned to the ventilation system accordingly or to adapt the filtration of the ambient air to be filtered. As a result, for example, the acoustic load on a person can be adjusted by the ventilation system to a germ load present in the ambient air, so that the acoustic exposure is intended to be minimal for the person.
  • the table device has a sensor device that can monitor a work area and a surrounding area, so that the ventilation system and the table device can adapt to changed environmental conditions.
  • the sensor device can have movement, distance or actuation sensors, with which a considerable automation of the table device according to the invention can be made possible.
  • a table height can be personalized for different people who want to work at the table and automatically adjusted when this person approaches.
  • the fan assigned to the ventilation system is switched off automatically by means of proximity sensors as soon as the work is finished and the person moves away from the table and the table equipment.
  • FIG. 1 shows a schematic representation of a table device with a ventilation system and a table.
  • a table device 1 with a table 2 is shown in FIG.
  • the three exhaust air openings 3 are fluidically connected to a ventilation system 5 via a hose pipe 8, with the three exhaust air openings 3 extracting any contaminated ambient air 6 from a work area 7 above the table surface 4 and feeding it to the ventilation system 5, which removes the possibly contaminated ambient air 6 with a Filter device filtered and also via two hoses 8 a supply air device 9 supplies.
