Description

Die Erfindung betrifft eine Schutzhaube, die das Arbeiten in Reinräumen unter dem Aspekt des Produktschutzes erleichtert.The invention relates to a protective hood, which facilitates working in clean rooms under the aspect of product protection.

Die Schutzhaube (mit Namen PM Clean Hood) ist eine freitragende Schutzhaube, die insbesondere für den Einssatz in Reinräumen konzipiert ist. In einem Reinraum können Produkte unter einer besonders verschmutzungsarmen Atmosphäre gefertigt werden. Dies ist bei Produkten der Elektrotechnik und Mikroelektrotechnik gefordert.The protective hood (with the name PM Clean Hood) is a self-supporting protective hood, which is especially designed for use in clean rooms. In a clean room, products can be manufactured under a low-pollution atmosphere. This is required for products of electrical engineering and microelectronics.

Normale, zur Zeit im Handel erhältliche Schutzhauben, verwenden die im Reinraum befindliche Atemluft zur Atemluftversorgung des Produktionspersonals oder es wird mit Hilfe eines Atemluftgebläses gereinigte Luft in die Haube geblasen. Dies kann beim Ausatmen dazu führen, dass verschmutze Partikel oder verbrauchte Luft aus der Haube in den Reinraum gelangt und die Produkte verunreinigt.Normal, currently commercially available protective hoods, use the clean air located in the breathing air for breathing air supply of the production staff or it is blown with the help of a breathing air blower cleaned air into the hood. When exhaling, this can cause contaminated particles or used air from the hood to enter the clean room and contaminate the products.

Eine Schutzhaube worin die Atemluft gefiltert in die Haube gelangt und die verbrauchte Luft über einem Partikelfilter an die Umgebung angegeben wird ist aus US 5,009,225 bekannt.A protective hood in which the breathing air filtered enters the hood and the spent air is indicated by a particle filter to the environment is off US 5,009,225 known.

Aufgabe ist es daher eine Schutzhaube bereitzustellen, die keine verunreinigte oder gebrauchte Luft entweichen lässt.The object is therefore to provide a protective hood that does not allow any contaminated or used air to escape.

Gelöst wird diese Aufgabe durch eine Schutzhaube, die dafür sorgt, dass die Atemluft (Frischluft) durch ein integriertes PS-Vlies gefiltert in die Haube gelangt und die verbrauchte Luft über einen P3-Partikelfilter an die Umgebung abgegeben wird. Die besonderen Filter lassen keine größeren Partikel in oder aus der Haube.This task is solved by a protective hood, which ensures that the breathing air (fresh air) filtered through an integrated PS fleece enters the hood and the spent air is discharged via a P3 particle filter to the environment. The special filters do not allow larger particles in or out of the hood.

So können keine Schmutzpartikel aus der Schutzhaube heraus in den Reinraum gelangen.So no dirt particles can get out of the protective hood into the clean room.

In einer anderen Ausführungsform der vorliegenden Erfindung basiert die Haube auf einem Unterdruckprinzip. In einer weiteren Ausführungsform wird mit Hilfe eines Atemluftgebläses ein Unterdruck in der Haube erzeugt. Hierdurch wird die Luft und somit auch die verunreinigte Luft stetig aus der Haube herausgesogen.In another embodiment of the present invention, the hood is based on a vacuum principle. In a further embodiment, a negative pressure in the hood is generated by means of a breathing air blower. As a result, the air and thus the contaminated air is continuously sucked out of the hood.

Ein Atemschutzgebläse mit PS3-Partikelfilter ist neben der Schutzhaube und dem Abluftschlauch eine weitere wesentliche Systemkomponente. Herkömmliche Atemschutzgebläse blasen die, unter Verwendung eines Atemfilters gereinigte Luft in eine Schutzhaube und erzeugen damit einen leichten Überdruck in der Haube. Das beim Einsatz der PM Clean Hood verwendete Atemschutzgebläse wirkt entgegengesetzt. Beim Einschalten des Atemschutzgebläses wird über den Abluftschlauch Luft über ein PS-Vlies irn oberen Kopfbereich durch die Schutzhaube angesaugt, wobei ein leichter Unterdruck in der Haube entsteht. Die abgesaugte Luft wird über den PS-Filter am Atemschutzgebläse in die Raumumgebung zurückgeführt.
Der Vorteil dieses Systems liegt darin, dass der Anwender stets von einem angenehmen Luftstrom im Bereich des Gesichts umgeben ist. Die ausgeatmete Luft wird unverzüglich abtransportiert. Eventuell in der Atemluft enthaltene biologische Agenzien, aber auch Partikel, wie Hautschuppen oder Haare, werden durch den PS-Filter, vorzugsweise ein P3-Partikelfilter festgehalten und können nicht in die Raumumgebung gelangen.
In einer weiteren besonderen Ausführungsform des erfindungsgemäßen Gebläses ist dies dadurch gekennzeichnet, dass das Atemluftgebläse motorunterstützt arbeitet und sich in einem Gehäuse befindet, in welchem zusätzlich auch noch ein Filtermodul angeordnet ist, in welchem sich der Partikelfilter befindet.A respiratory fan with PS3 particle filter is a further essential system component in addition to the protective hood and the exhaust hose. Conventional respirators blow in air that has been purified using a breathing filter Protective hood and thus generate a slight overpressure in the hood. The respirator blower used when using the PM Clean Hood has the opposite effect. When the respiratory blower is switched on, air is drawn in via the exhaust air hose via a PS fleece in the upper head area through the protective hood, whereby a slight negative pressure is created in the hood. The extracted air is returned to the room environment via the PS filter on the respirator fan.
The advantage of this system is that the user is always surrounded by a pleasant flow of air around the face. The exhaled air is removed immediately. Any biological agents contained in the breath, as well as particles such as dander or hair, are captured by the PS filter, preferably a P3 particulate filter, and can not enter the room environment.
In a further particular embodiment of the blower according to the invention, this is characterized in that the breathing air blower operates motor-assisted and is located in a housing in which additionally a filter module is also arranged, in which the particle filter is located.

Dieses in einem Gehäuse befindliche Atemluftgebläse gewährleistet dem Träger der Schutzhaube mobil und beweglich seine Tätigkeit auszuüben. Das Gebläse zur Erzeugung des Unterdrucks - im Normalfall reicht ein Gebläse aus - befindet sich in dem gleichen Gehäuse wie der eigentliche Partikelfilter und wird beispielsweise an der Schutzhaube befestigt. Das in dem Gehäuse befindliche Filtermodul dient zur Aufnahme des Partikelfilters. Dort können dann wahlweise Partikel- oder Kombinationsfilter verschiedenster Stärke eingelegt werden. Das motorunterstützte Gebläse befindet sich ebenfalls in dem Filtergehäuse und befördert die verbrauchte Luft durch den Filter hinaus.This located in a housing breathing air fan ensures the wearer of the guard mobile and mobile exercise his job. The blower for generating the negative pressure - normally a blower is sufficient - is located in the same housing as the actual particle filter and is attached, for example, to the protective hood. The filter module located in the housing serves to receive the particle filter. There can then be optionally inserted particle or combination filter of various strengths. The motor-assisted fan is also located in the filter housing and conveys the spent air through the filter.

Denkbar sind Gebläse, die nach dem Prinzip von Axialventilatoren arbeiten. Sie sind eine sehr gebräuchliche Bauform. Die Drehachse des Axiallaufrades verläuft parallel bzw. axial zum Luftstrom. Die Luft wird durch das Axiallaufrad, ähnlich wie bei einem Flugzeug- oder Schiffspropeller, bewegt. Die Vorteile von Axialventilatoren sind die, im Verhältnis zum hohen geförderten Luftdurchsatz, geringen Abmessungen. Wichtig ist allerdings, dass der gebläseunterstützte Filter mit integriertem Motor nicht zu schwer ist. Der in dieser Erfindung entwickelte Motor hat ein Gewicht von 90 g.Conceivable blowers that work on the principle of axial fans. They are a very common design. The axis of rotation of the axial impeller is parallel or axial to the air flow. The air is moved by the axial impeller, similar to an aircraft or ship propeller. The advantages of axial fans are their small dimensions in relation to the high air flow rate. However, it is important that the fan-assisted filter with integrated motor is not too heavy. The engine developed in this invention weighs 90 g.

In einer weiteren Ausführungsform der Erfindung ist die Schutzhaube so gestaltet, dass sie sich jeder Kopfform anpasst. Dies wird mit Hilfe von elastischen Bändern erreicht. Die gesamte Schnittführung der Haube und die Anbringung passformoptimierender Nähte erhöhen den Tragekomfort gegenüber herkömmlichen Hauben wesentlich. Unterstützt durch die Verwendung von elastischen Bändern passt sich die Haube jeder beliebigen Kopfform an und sorgt für ausreichende Bewegungsfreiheit. Auch für Bart- und Brillenträger hervorragend geeignet.
Die erfindungsgemäße Ausführungsform der Schutzhaube, die die elastischen Bänder der Haubeninnenseite mit Bändern, vorzugsweise ebenfalls elastischen Bändern, auf der Außenseite der Haube verbindet, hat den Vorteil, dass der Träger die Haube nach dem Aufsetzen an die Kopfform anpassen kann. Dies wird durch ein Festziehen der Bänder erreicht. Die Haube kann so leicht aufgesetzt und wieder abgenommen werden. Beim Abnehmen können Haarbänder und Haarnetze herabgezogen werden und den Reinraum kontaminieren. Die Verbindung der Innenseitenbänder mit den Außenseitenbändern wird durch ein befestigen der Bänder jeweils an der Haube bewerkstelligt.
In einer weiteren Ausführungsform der Schutzhaube ist diese dadurch gekennzeichnet, dass die Haube einen doppelten Kragen aufweist. Die Schutzhaube ist mit zwei übereinander liegenden Kragen ausgestattet. Der innenliegende, ergonomisch zugeschnittene Kragen ist dazu bestimmt, unter der Oberbekleidung des Anwenders getragen zu werden. Um ein Verrutschen des Unterkragens beim Ankleiden zu verhindern ist dieser zusätzlich mit einem Fixierungsband ausgestattet, welches der Träger unter dem Brustkorb verschließt.
Der Oberkragen liegt im Schulterbereich auf der Oberbekleidung auf. Er ist im Bereich der äußeren Schnittkanten umgenäht. Zur Vorbereitung des Ankleidens verfügt die Haube oben über eine praktische Aufhängeschlaufe.
Es kann allerdings auch eine Schutzhaube mit nur einem Kragen verwendet werden, der sorgfältig die Abschirmung der Aussenluft von der Innenluft abschirmt. Dieser wird durch den erzeugten Unterdruck noch zusätzlich an die Schutzkleidung des Trägers gesaugt. Dieser Kragen kann unter der Sicherheitskleidung getragen werden und trägt so effektiv zur Abdichtung und Verhinderung der Verunreinigung des Raumes bei.
Die Schutzhaube ist so ausgestaltet, dass sie ohne Kopfgestell freitragend ist.
Die Schutzhaube verfügt vorzugsweise über ein Visier, dass die optische Klasse 1 hat.
Die Schutzhaube besteht aus einem begrenzt einsetzbaren Material. Das Visier erfüllt die Anforderungen an die optische Klasse 1 und ist fest mit der Haube verbunden. Die Visiergröße ist so ausgelegt, dass sie das natürliche Sichtfeld nicht beeinträchtigt. Gleichzeitig werden durch die definierte Visiergröße Blendeinwirkungen durch Lichteinfall von hinten nahezu ausgeschlossen, was zu einem erhöhten Tragekomfort und Sicherheit beiträgt. Das halbkreisförmig gewölbte Visier lässt es zu, dass der Träger den Kopf nach oben und unten, rechts und links wenden kann, ohne dass sein Sichtfeld von dem undurchsichtigen Teil der Schutzhaube beeinträchtigt wird.
In einer weiteren Ausführungsform der Schutzhaube ist diese dadurch gekennzeichnet, dass der Abluftschlauch mit einem speziellen Befestigungsclip mit der Haube verbunden wird. Hierdurch kann der Atemluftschlauch, je nachdem wo sich der Befestigungsclip an der Schutzhaube befindet schnell und unkompliziert mit der Schutzhaube verbunden werden.In a further embodiment of the invention, the protective hood is designed so that it adapts to any head shape. This is achieved by means of elastic bands. The entire cut of the hood and the fitting optimal fit seams increase the comfort compared to conventional hoods much. Supported by the use of elastic bands, the hood adapts to any head shape and ensures sufficient freedom of movement. Also suitable for beard and eyeglass wearers.
The embodiment of the protective hood according to the invention, which connects the elastic bands of the inside of the hood with bands, preferably also elastic bands, on the outside of the hood has the advantage that the wearer can adapt the hood to the head shape after placement. This is achieved by tightening the bands. The hood can be easily put on and taken off again. When removing hair bands and hair nets can be pulled down and contaminate the clean room. The connection of the inner side bands with the outer side bands is accomplished by attaching the bands respectively to the hood.
In a further embodiment of the protective hood, this is characterized in that the hood has a double collar. The protective hood is equipped with two superimposed collars. The inside, ergonomically cut collar is designed to be worn under the outerwear of the user. In order to prevent slippage of the lower collar when dressing this is additionally equipped with a fixing band, which closes the carrier under the rib cage.
The upper collar lies in the shoulder area on the outer clothing. It is sewn around the outer edges. To prepare for dressing, the hood has a practical suspension loop at the top.
However, it is also possible to use a protective hood with only one collar, which carefully shields the shielding of the outside air from the inside air. This is additionally sucked by the generated negative pressure to the protective clothing of the wearer. This collar can be worn underneath the safety clothing to effectively seal and prevent contamination of the room.
The protective cover is designed so that it is cantilevered without head frame.
The guard preferably has a visor that has the optical class 1.
The protective cover consists of a limited usable material. The visor meets the requirements of the optical class 1 and is firmly connected to the hood. The visor size is designed so that it does not affect the natural field of view. At the same time, the defined visor size virtually eliminates the effects of glare from the rear, which contributes to increased wearing comfort and safety. The semi-circular arched visor allows the wearer to turn his head up and down, right and left, without his field of view being affected by the opaque part of the guard.
In a further embodiment of the protective hood, this is characterized in that the exhaust hose is connected to the hood with a special fastening clip. This allows the breathing air hose, depending on where the clip is located on the guard quickly and easily connected to the guard.
