Abstract
A blower register includes a movable terminal, a plurality of fixed terminals to which the movable terminal is selectively connected, a plurality of resistors installed on the downstream side of the fixed terminals to adjust a current value of an electric current applied to a blower, and a current flow control part configured to subdivide the current value of the electric current in a number larger than the number of the fixed terminals and to form current flow paths through the resistors so that a rotation speed level of the blower is controlled to one of rotation speed levels larger in number than the fixed terminals.
Claims9
A blower register, comprising:
- a movable terminal;
- a plurality of fixed terminals to which the movable terminal is selectively connected;
- a plurality of resistors installed on the downstream side of the fixed terminals to adjust a current value of an electric current applied to a blower;
- and
- a current flow control part configured to subdivide the current value of the electric current in a number larger than the number of the fixed terminals and to form current flow paths through the resistors so that a rotation speed level of the blower is controlled to one of rotation speed levels larger in number than the fixed terminals;
- wherein two or more of the resistors are connected in series to the blower so as to adjust the current value of the electric current applied to the blower while allowing the electric current supplied to one of the fixed terminals to sequentially pass through the resistors, and
- the current flow control part is configured to, when the electric current is supplied to one of the fixed terminals, control a flow of the electric current so that the electric current bypasses one or more of the resistors existing on the downstream side of one of the fixed terminals to which the electric current is supplied, whereby the current flow control part variably controls the number of the resistors through which the electric current passes, and subdivides the current value of the electric current applied to the blower.
