Port connection；Temperature detector TS is connect with the fifth port of control chip C；The first port and the second relay of second relay S2
It is coil between the second port of S2.
For first heater circuit by interface CN connection alternating current, manual switch S3 is manual control switch；Manual switch S3 is closed
When conjunction, alternating current is that the first heater strip H1 and the first indicator light L1 powers by the first temperature limiter T1 and temperature controller A1, the first heating
Silk H1 heats the water in water tank, and the first indicator light L1 is bright；When manual switch S3 is disconnected, the first heater circuit unpowered is returned
Road does not work；Temperature controller A1 is used to detect the water temperature in water tank, and temperature detect switch (TDS) is normally closed, makes a reservation for when the water temperature in water tank reaches first
At 75 DEG C of temperature, the temperature detect switch (TDS) of temperature controller A1 is disconnected, and the first heater circuit is made not work；First temperature limiter T1 is for detecting water
Water temperature in case, the first temperature limiter T1 is normally closed, if temperature controller A1 failure, when water temperature reaches 90 DEG C of the second preset temperature, and first
Temperature limiter T1 is disconnected, i.e. separated, the Yi Ji of the first port of the first temperature limiter T1 and the second port of the first temperature limiter T1
The 4th port of the third port of one temperature limiter T1 and the first temperature limiter T1 it is separated, so that the first heater circuit is not worked, with
Water temperature over-high in caisson causes safety problem；First temperature limiter T1 needs hand-reset after disconnecting.
When the interface CN connection alternating current of the first heater circuit, alternating current progress voltage is converted into first voltage by transformer VT
12V is exported to be closed between the third port for making the first relay S1 to the first relay S1 and the 4th port of the first relay S1
It closes, while making to be closed between the first port for controlling chip C and the second port for controlling chip C, the first power supply B1, the first relay
Power circuit is formed between device S1 and control chip C, the first power supply B1 is control chip C power supply；Due to controlling the first of chip C
It is closed between port and the second port for controlling chip C, makes the 4th port of the third port for controlling chip C and control chip C
It is separated, while making the separated of the third port of the second relay S2 and the 4th port of the second relay S2, so that
The circuit of two heater circuits disconnects and can not work.
When interface CN does not connect alternating current, the first relay S1 does not have a power supply of first voltage, and the of the first relay S1
Three ports and the 4th port of the first relay S1 it is separated, between the first power supply B1, the first relay S1 and control chip C
Circuit power-off, the first power supply B1 can not for control chip C power supply, control chip C first port and control chip C second
Port it is separated, therefore control chip C third port and control chip C the 4th port between be closed, make the second relay
It is closed between the third port of S2 and the 4th port of the second relay S2, the circuit of the second heater circuit is powered on.
In second heater circuit, when the second relay S2 closure, second source B2 is that the second heater strip H2 powers, second
Heater strip H2 heats the water in water tank, and the second indicator light L2 is bright；Temperature detector TS is used to detect water temperature and the life in water tank
At water temperature signal, when the water temperature in water tank reaches 75 DEG C of the first predetermined temperature, temperature detector TS sends water temperature signal to controlling core
Piece C, control chip C control the interruption of the third port of control chip C and the 4th port of control chip C according to water temperature signal
It opens, so that the third port of the second relay S2 and the 4th port of the second relay S2 is separated, therefore the second heater circuit
Circuit disconnect can not work；Second temperature limiter T2 is used to detect the water temperature in water tank, and the second temperature limiter T2 is normally closed, works as temperature detector
When TS failure, when water temperature reaches 90 DEG C of the second preset temperature, the second temperature limiter T2 is disconnected, i.e. the first port of the second temperature limiter T2
With the of separated and the second temperature limiter T2 the third port of the second port of the second temperature limiter T2 and the second temperature limiter T2
Four ports it is separated, make the second heater strip H2 that can not power from second source B2, the first heater circuit circuit disconnect can not work
Make, is caused danger with the water temperature over-high in caisson；Second temperature limiter T2 needs hand-reset after disconnecting.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present invention
Within.
