Air outlet with integrated air deflection and modular hose size adjustment

Abstract

Air outlet for discharging air, characterized in that the air outlet has struts (6) in the area of the outflowing air

Description

[0001] The present invention also relates to an air outlet with integrated air deflection and modular hose size adjustment, which enables the removal of air through window gaps (11). Common trade names in Germany are air conditioning adapters and window nozzles. These outlets are required for devices such as air conditioners or tumble dryers, which have an air flow to be removed and whose exhaust hose diameter is wider than the available window gap.

[0002] Desirable properties of the outlets are (a) that they can be mounted and dismounted on the window with little effort to enable the window to be closed and opened, (b) that the cross-sectional area of ​​the air flowing through the outlet is not excessively reduced, (c) that the air flow is redirected towards the floor after leaving the outlet so that it does not collide with structural features such as window frames, (d) that the outlet is secured in its position against slipping and sliding back, and (e) that the outlet can be mounted on the widest possible selection of hose diameters of the device.

[0003] Known outlets used to exhaust air have the disadvantage that the fixing in the mounting position or securing against slipping back of the outlet under point (d) is carried out by means of clamping force and is therefore inadequate or not possible depending on the local mounting position or existing window gap. The connection option to different hose diameters required under point (e) is made possible by adjusting the outlet diameter and producing it using additive manufacturing (3D printing). This has the disadvantage that each outlet only fits one hose size and results in increased inventory levels during sales. The deflection of the air flowing out of the outlet required under point (c) is achieved by an additional component which is attached to the end of the outlet and redirects the air flow. However, since the provision of different outlet sizes, as described in point (e), usually requiresWhen additive manufacturing processes are used with limited production capacities due to the long production times, the additional components required severely restrict the production of high quantities. In addition, the additional components often increase the component cross-section and make it difficult to install the outlet in gaps with narrow widths or heights.

[0004] The present invention has functional and structural features that satisfy the aforementioned desirable characteristics without the disadvantages of known outlets. This will become apparent from the following description of a preferred embodiment thereof, given purely as a non-limiting example, with reference to the appended claims, in which: Fig. 1: A representation of the outlet in mounting position, by fixing the adapter with a ball chain Fig. 2: A representation of the outlet in which the area of ​​the outflowing air is visible Fig. 3: An illustration of the outlet's expandability to accommodate a wide range of hose sizes

[0005] The fixing in the mounting position required under points (a) and (d) or simple assembly and disassembly of the outlet (13§) is carried out by means of a flexible ball chain (see Fig. 1). The outlet-side connection to the ball chain is made by pressing the balls (1) mounted on the ball chain into identically shaped recesses (2) located at the outlet. The identically shaped recesses are oriented and dimensioned in such a way that the balls remain in position by means of frictional locking, and by means of positive locking they prevent the balls from being pulled out under load in the direction of pull. For the permanent attachment of the ball chain to the surrounding area, such as a window frame, window sash, wall (12), the balls at the end of the ball chain are fastened to inserts (3), which also have the identically shaped recesses described at the beginning. These inserts are then inserted into receptacles (4) which are attached to the surrounding, stationary part by means of an adhesive connection. The described connection of the outlet to a fixed point by means of a ball chain enables quick and easy installation by means of a pulling out orreinserting the inserts into the holders.

[0006] The deflection of the outflowing air required under point (c) (see Fig. 2) is achieved by means of an air guide deflector (5) incorporated into the outlet, which requires no additional components. The individual, air-guiding, vertical struts (6) are designed in such a way that, during additive manufacturing, supports or similar elements are not required in the deflection area, which exceeds an inclination of 45°, or in the area of ​​the horizontal surfaces (7).

[0007] The connection option to different hose diameters (14) required under point (e) is achieved by means of a modular design of the outlet (see Fig.3). The outlet is identical for all hose diameters. It features grooves (8) that allow for screwing in exhaust hoses with the most common outer diameters, ranging from 14.5 to 15 cm, regardless of the direction of rotation.

[0008] For hose diameters that differ, the outlet has a thread (9) to which adapter pieces (10) can be attached, adapted to the respective hose size and manufactured in any size. The use of identical outlets and the installation of smaller adapter pieces, exclusively for hose diameters differing by 14.5 - 15 cm, enables series production of the outlets while simultaneously maintaining low inventory levels.
