The present invention relates to an air deflector in accordance with the preamble of claim 1 and also to a method for mounting an air deflector in accordance with the preamble of claim 13.
Air deflectors are used to deflect the air extracted from a chamber and filtered by an extractor hood (fat filter and/or odor filter) from the air extraction duct of the extractor hood back into the chamber. In such cases, as is known from publications DE 101 18 881 A1, EP 1 843 100 A2 and DE 200 05 154 U1 for example, the air flow can be divided up by an air deflector and diverted by around 90 degrees in two different directions.
Air deflectors known from the prior art are made from two substantially identical parts screwed together. Screwing the parts together allows dissimilarities of the respective components to be compensated for during assembly. However screwing the parts together demands a comparatively large amount of time during assembly or mounting of the air deflector.
For wall mounting conventional air deflectors, as are shown for example in FIGS. 14 and 15 of publication DE 101 18 881 A1, are screwed to the wall via their rear panel and where necessary two further attachment plates to an attachment bracket of the air deflector or of the inner duct of the air deflector. In such cases the width of the air deflector is predetermined by its construction. Different widths of air defector are thus used for air extraction ducts of different widths.
Using as its starting point the disadvantages and shortcomings set down above, as well as taking due account of the outlined prior art, the underlying object of the present invention is to develop a deflector plate of the type described above so that the components of the defector plate can be assembled easily and rapidly. To facilitate the mounting of the deflector plate the plate should be constructed from as few individual components as possible.
This object is achieved by a deflector plate with the features specified in claim 1 and by a method with the features specified in claim 13. Advantageous embodiments and useful developments of the present invention are identified in the respective subclaims.
The present invention is thus based on the idea that the deflector plate can be constructed from two components by plugging them into each other and optionally by latching them. To this end the preferably identical components are able to be joined by at least one plug connection in a detachable or non-detachable manner. By comparison with conventional deflector plates, this makes a reduction in parts and simpler and faster mounting possible.
In accordance with an advantageous embodiment of the present invention the components of the deflector plate, for diverting the air extracted by the extractor hood, for example from a wall hood or island hood embodied for recirculating air operation, have at least one first and at least one second deflector element in each case, as well as if necessary at least one further deflector element. The deflector elements are arranged in relation to each other such that a deflector channel for diverting at least a part of the air extracted by the extractor hood back into the chamber is formed in the space between two deflector elements.
To keep the number of individual parts of the air deflector as small as possible, the first and/or the second deflector element and/or the further deflector element are preferably embodied in one piece with the respective component of the air deflector. In this case at least one plastic is preferably used for manufacturing the first and/or the second and/or the further deflector element.
The person skilled in the art will especially appreciate an exemplary embodiment of the present invention which, to create a simple variation in the width of the air deflector, has at least one auxiliary element able to be connected with the air deflector, for example at least one additional component able to be plugged into the air deflector. This auxiliary element, preferably embodied in one piece, enables the air deflector to be mounted in a simple manner in different widths of exhaust air duct. In this case the auxiliary element preferably directly adjoins in its usage position the air outlets of the components of the air deflector connected to each other and the air outlets of the exhaust air duct of the extractor hood.
The attachment of the air deflector to the exhaust air duct of the extractor hood can be achieved simply and quickly by means of a retaining element to suspend, attach or plug in the air defector on or from a mounting bracket able to be arranged on the exhaust air duct. This exhaust air duct can be assigned to a wall hood or an island hood for example.
In the wall hood embodiment the mounting bracket is preferably embodied to both accept the air deflector and to attach the exhaust air duct to the wall. In this case a desired distance between the air deflector and the wall can be created using the shape of the mounting bracket and/or via at least one spacer arranged on the air deflector.
The present invention thus further relates to a mounting system for attaching an air deflector
which mounting system features an air deflector of the type described here and a mounting bracket of the type described here.
The present invention finally relates to the use of an air deflector in accordance with the type described here for an air extractor hood embodied for exhaust air or exhaust air and recirculating air operation, for example for an wall cooker hood or island cooker hood.
As already explained above, there are different possibilities of arranging and developing the teaching of the present invention in an advantageous manner. In this context the reader is referred on the one hand to the claims subordinate to claim 1 as well as to claim 13, on the other hand, further embodiments, features and advantages of the present invention are explained below in greater detail with reference to aspects such as the exemplary embodiment illustrated in

Embodiments, elements or features which are the same or similar in design are provided with identical reference signs in
The splitting up and the diversion of the air flow is brought about by the particular constructive design of the air deflector 100. Its components 10, 20 are each delimited on their upper or lower side by an air guide element embodied as a deflector element 30, 32 or 40, 42. Located between the upper and the lower air guide element 30, 32 or 40, 42 are further air guide elements 34 or 44 respectively. In this way a number of deflector channels or air guide channels 36 are formed, by means of which the air flow directed through the chimney exhaust pipe 310 is split up and conveyed to the air outlets 320 of the exhaust air duct or chimney 300.
During mounting, or to put it more precisely during assembly of the air deflector 100, the first component 10 is plugged into the further component 20 by means of plug connections 12, 22 and is connected to the said component in a detachable or non-detachable manner, especially latched onto it (cf.
To adapt the width of the air deflector 100 to the width of the chimney 300, an auxiliary element 50 can be plugged in, preferably on the air outlet side 14, 24 of the air deflector 100 (cf.
The air deflector 100 can be plugged into or suspended from a mounting bracket shown in
In addition to supporting the air deflector 100, the mounting bracket 200 depicted in
To obtain a predetermined spacing between the air deflector 100 and the wall, the air deflector 100 has spacers 70 on its side facing towards the wall. The spacing of the air deflector 100 from the wall is also achieved by the shape of the mounting bracket 200, especially by an area 230 of the mounting bracket 200 spaced away from the wall.
The chimney 300 depicted in
As an alternative the air deflector 100 can also be mounted in an extractor hood arranged freely in a space, for example in an island cooker hood.
The air deflector 100 shown in
Furthermore no air deflector is known from the prior art featuring pluggable extension or auxiliary elements 50 for different widths of chimney.
A further advantageous criterion for distinguishing the deflector from the prior art is the air guide channels 36 which are formed between the first air guide element 30, 40 and/or the second air guide element 32, 42 and/or the further air guide elements 34, 44.
By contrast with the prior art, the air guide elements 30, 40, 32, 42, 34, 44 are preferably substantially made of plastic and can thus be manufactured especially easily and at low-cost.
