It expends.
A kind of heating device with relay is described in 3212431 A1 of document DE.However, not describing relay
Accurate setting.How to keep temperature stabilization also undecided when desired temperature levels once reach.
A kind of nonstorage calorifier is described in 102010009340 A1 of document DE, wherein return using additional heater wire
Road is used for secondary heating region.The dual line length for needing the heater wire of Second Type thus or being sutured.The two helps to make
Must manufacture the more complicated, time more expends and more expensive.Furthermore the circuit needs more and more electric currents.
Therefore it is desirable that, seat is quickly heated, and can be realized the equilibrium temperature in continuous service herein
And low energy consumption.
Summary of the invention
A kind of electric register is proposed in this context, there are at least two heating devices, the electricity register is also
Include at least one temperature-detecting device, the temperature-detecting device is used to detect the temperature of at least one heating device and defeated
Switching signal out；At least one is used to adjust the regulating device of the power of the heating device, and the regulating device has at least
One relay, the relay are electrically connected to receive switching signal and by the switching signal with the temperature-detecting device
The temperature stabilization on the surface being heated can be switched so that between first switch state and second switch state；Wherein,
At least two heating devices are electrically connected with voltage source by the relay parallel to each other under the first switch state, and
At least two heating devices are electrically connected by the relay with being serially connected under second switch state with voltage source；And switch
Device, the switching device be configured to be made according to the measurement result of the temperature-detecting device electric register no-voltage and/
Or no current connect.
