Abstract

The rectangular ventilation supply duct (1) has a longitudinal slot in its underside through which air flowing in the duct enters the room served. The duct complete with slot is formed from a foamed insulating material which sets with hard inner and outer surfaces retaining a soft foam structure inside. The inner surface of the duct so formed is lined with a soft bud solid insulating material (2) has sound absorbing as well as thermally insulating properties. The construction provides an insulated duct without the cost and time of erecting metal ducts with separate insulation applied to them. The same construction can also be used for plain supply or extract ducts without the supply slot.

Description

Beschreibung Luftkanäle und SuftinduktorenDescription Air ducts and scent inductors

Luftkanäle und Luftinduktoren verschiedenster Art sind bekannt.Various types of air ducts and air inductors are known.

Sie werden aus einem Blechmantel gefertigt und innen mit Glaswolle oder Schaumstoff isoliert. Der Außenmantel kann auch aus Kunststoffplattenmaterial gefertigt sind, indem man Platten zur Kanalform biegt oder schweißt.They are made from a sheet metal jacket and have glass wool on the inside or foam insulated. The outer jacket can also be made of plastic sheet material are made by bending or welding plates to form a channel.

Diese Art der Fertigung ist zeitraubend, unwirtschaftlich, mit maßlichem Risiko behaftet und zudem auch nicht risikofrei für die Funktion, da sich die Isolation lösen kann0 Der Erfinder hat es sich zur Aufgabe gemacht, diese Nachteile zu eliminieren. Er schlägt vor, diese Kanäle und Luftinduktoren aus Schaumstoff herzustellen. Dieser Schaumstoff kann einen sandwichartigen Aufbau beim Schäumen gewährleisten, z.B. als Integralschaum ausgebildet sein. Dabei kann eine Glaswollisolation oder eine andere Art der Isolation innen sofort mit angeschäumt werden. Es würde sich so um Formstücke handeln, die maßgenau sind, bei denen ein Loslösen der zusätzlichen Isolation unmöglich ist und die Wirtschaftlichkeit wesentlich erhöht ist.This type of production is time-consuming, uneconomical, with dimensions Risky and also not risk-free for the function, since the isolation can solve0 The inventor has set himself the task of eliminating these disadvantages. He suggests making these ducts and air inductors out of foam. This Foam can provide a sandwich-like structure when foaming, e.g. be designed as integral foam. A glass wool insulation or a other type of insulation can be foamed onto the inside immediately. It would be so Act fittings that are dimensionally accurate, in which a loosening of the additional insulation is impossible and the economy is significantly increased.

Abbildungen Luftkanäle bzw. Luftinduktoren Abb. 1 zeigt einen tuftinduktor (1). Der Querschnitt zeigt den typischen Aufbau. Die Isolierung (2) falls eine extra Isolierung eingebaut wird, die in der Hauptsache als Schalisolation (z.B. Glaswolle) dient, liegt wider äußeren Hülle (3). Diese äußere Hülle ist dargestellt als Integralsohaum, d.h. beim Schäumen entsteht außen und innen eine feste Haut und dazwischen befindet sich die eigentliche Schaumstruktur.Illustrations of air ducts and air inductors Fig. 1 shows a tufted inductor (1). The cross-section shows the typical structure. The insulation (2) if an extra one Insulation is installed, which is mainly used as sound insulation (e.g. glass wool) serves, lies against the outer shell (3). This outer shell is represented as an integral foam, i.e. when foaming creates a firm skin on the outside and inside and in between the actual foam structure.
