Specifically, the controlling switch component in above-described embodiment can be relay.
As shown in figure 5, be a kind of control system of electric heater disclosed in the embodiment of the present invention, including：Controller 51, three
Group electric heating element；Wherein：
First group of electric heating element includes the first relay K1, the second relay K2, the 7th relay K7, the 9th relay
K9 and the first electric heater HEAT1；
Second group of electric heating element includes the 11st relay K11, the 12nd relay K12, the 3rd relay K3, the 4th
Relay K4, the tenth relay K10 and the second electric heater HEAT2；
3rd group of electric heating element includes the 8th relay K8, the 5th relay K5, the 6th relay K6, the 13rd relay
Device K13 and the 3rd electric heater HEAT3.
In the control process of electric heater, by the orderly suction to above relay and and disconnect, by electric heater
HEAT1, HEAT2, HEAT3 electric heating tube are combined in series operation and parallel running, converted.So as to reach change fortune
The purpose of row resistance and power.
For example, the first relay K1, the second relay K2, the 3rd relay K3, the 4th relay are controlled by controller 61
Device K4, the 7th relay K7, the tenth relay K10, the 13rd relay K13 adhesive, remaining relay is controlled to disconnect, can
To realize the electrical heating wire of series connection the first electric heater of electric conduction HEAT1 electrical heating wire and the second electric heater HEAT2, first
Resistance after electric heater HEAT1 and the second electric heater HEAT2 series connection can be changed into the electricity of the first electric heater HEAT1 and second
4 times of heater HEAT2 parallel connections, the electrical heating power of series connection is in parallel 1/4.As control the tenth relay K10 and the 13rd
Relay K13 disconnects, and inhales and the 9th relay K9, the 11st relay K11 and the 12nd relay K12, it is possible to achieve in parallel
Turn on the first electric heater HEAT1 electrical heating wire and the second electric heater HEAT2 electrical heating wire.Resistance so after parallel connection
It is 1/4 times to connect before, electrical heating power is in parallel 4 times.Similarly, can analogize successively：
First relay K1, the second relay K2, the 7th relay K7, the 12nd relay are controlled by controller 61
K12, the 8th relay K8, the 5th relay K5, the 6th relay K6, the 13rd relay K13 inhale and, it is possible to achieve series connection lead
Be powered the first electric heater HEAT1 electrical heating wire and the 3rd heater HEAT3 electrical heating four, so connect after resistance be
4 times of first electric heater HEAT1 and the 3rd heater HEAT3 parallel connections, electrical heating power is parallel connection 1/4, passes through controller 61
Control the 13rd relay K13 disconnect, then by the 9th relay K9, the tenth relay K10 and the 11st relay K11 inhale and,
Then the first electric heater HEAT1 and the 3rd heater HEAT3 is in parallel.Resistance after so in parallel is in parallel 1/4 times, electrical heating
Power is in parallel 4 times.
13rd relay K13, the 5th relay K5, the 6th relay K6, the 8th relay are controlled by controller 61
K8, the 12nd relay K12, the 3rd relay K3, the 4th relay K4, the 9th relay K9 inhale and, then can realize series connection
Turn on the second electric heater HEAT2 electrical heating wire and the 3rd electric heater HEAT3 electrical heating wire, such second electric heater
HEAT2 and the 3rd electric heater HEAT3 series connection after resistance be the second electric heater HEAT2 and the 3rd electric heater HEAT3 simultaneously
4 times of connection, electrical heating power are parallel connections 1/4, control the 9th relay K9 to disconnect by controller 61, then inhale and the tenth relay
K10 and the 11st relay K11, then the second electric heater HEAT2 and the 3rd electric heater HEAT3 is in parallel.So after parallel connection
Resistance is 1/4 times of series connection, and electrical heating power is 4 times of series connection.
By controller 61 control the first relay K1, the second relay K2, the 3rd relay K3, the 4th relay K4,
5th relay K6, the 6th relay K6, the 7th relay K7, the 8th relay K8, the tenth relay K10, the 11st relay
Device K11 inhale and, then the first electric heater HEAT1 of series connection conducting, the second electric heater HEAT2 and the 3rd electric heater HEAT3, this
Resistance after sample series connection is in parallel 9 times, and electrical heating power is parallel connection 1/9, then is inhaled and the 9th relay K9, the 12nd relay
K12, then the first electric heater HEAT1, the second electric heater HEAT2 and the 3rd electric heater HEAT3 become in parallel.It is so in parallel
Resistance afterwards is 1/9 times to connect before, and electrical heating power is and connected 9 times.
It can thus be seen that the present invention can will be multigroup or multigroup in electric heater between series connection and parallel connection individually
Or combination application adjusts electrical heating power.Electric thermal power can be adjusted at any time reaches required temperature.Simultaneously can also be with
Meaning adjustment starts resistance, controls starting current.
