First Claim
Patent Images
1. An electric heating device used as an auxiliary heating for motor vehicles comprising:
- a plurality of heating elements, which are combined so as to form a heating block, wherein each of said heating elements is controlled separately to heat a particular portion of a total air flow to be heated, the remaining portion of the total air flow being heated only by the remaining heating element; and
a control device which controls the heating power of each of the heating elements, the heating power for each of said heating elements being separately adjustable, wherein the control changes an allocation of the heating power to each of the heating elements at predetermined time intervals.

18. A motor vehicle auxiliary electric heating device comprising:
-
a plurality of separately controllable heating elements which are connected to one another so as to form a heating block, wherein each of said heating elements is adapted to be controlled separately to heat a particular portion of a total air flow to be heated, the remaining portion of the total air flow being heated only by the remaining heating elements; and
a control device for controlling the heating elements, the heating power for each of said heating elements being separately adjustable, wherein the control device is configured such that, when control of the individual heating elements is effected, an allocation of the respective separately adjustable heating powers to the individual heating elements is changeable at predetermined time intervals. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. A method of controlling a motor vehicle auxiliary electric heating device, the heating device comprising a plurality of separately controllable heating elements which are interconnected so as to form a heating block, the method comprising:
-
adjusting the heating power for each of said heating elements separately so that each of said heating elements heat only a portion of the total air flow to be heated, the remainder of the total air flow being heated by the remaining heating elements, and changing the allocation of the respective separately adjusted heating powers to the individual heating elements at predetermined time intervals. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
