Mixer for mixing air flows

摘要

A mixer for mixing air flows is provided that can include an air duct, which has at least one hot air duct and one cold air duct, wherein an air flow through the hot air duct and through the cold air duct can be controlled by a respective mixing flap. A heating element is arranged in the hot air duct in order to heat the air passing through the hot air duct. Furthermore, the mixer can include a mixing chamber, which is connected to an air outlet side of the hot air duct and of the cold air duct of the air duct such as to enable fluid flow. The mixing chamber can have air guiding elements, which are arranged in such a way that air flowing out of an air outlet side of the hot air duct crosses air flowing out of an air outlet side of the cold air duct.

主权项

1. A mixer for mixing air flows, the mixer comprising:
an air duct that has at least one hot air duct and one cold air duct, an air flow through the hot air duct and through the cold air duct is controllable via respective mixing flaps; a heating element arranged in the hot air duct for heating the air passing through the hot air duct; and a mixing chamber that is fluidically connected to an air outlet side of the hot air duct and of the cold air duct of the air duct, the mixing chamber having air guiding elements that are arranged such that air flowing out of an air outlet side of the hot air duct crosses air flowing out of an air outlet side of the cold air duct, wherein the mixing chamber is divided into a plurality of levels by the arrangement of at least one flat air guiding planar element; wherein, in the mixing chamber, one of the air guiding elements extends from a region of the air outlet side of the air duct between the hot air duct and the cold air duct to an outlet opening of the mixing chamber, and wherein the one air guiding element extends only into a subregion of the volume of the mixing chamber, which is provided for guiding an air flow out of the hot air duct, wherein, in the mixing chamber, a further air guiding element extends from a region of the air outlet side of the air duct between the hot air duct and the cold air duct to an outlet opening of the mixing chamber, and wherein the further air guiding element extends only into a subregion of the volume of the mixing chamber, which is provided for guiding an air flow out of the cold air duct, and wherein the one air guiding element and the further air guiding element are arranged on opposing surfaces of one flat air guiding planar element.
