All being connected with the 4th port of the second temperature limiter T2, the 3rd port of the second temperature limiter T2 is connected with the negative pole of second source B2.
In control circuit, the first input end of transformer VT and second port of the first temperature limiter T1 connect, transformer VT
The second input and the 4th port of the first temperature limiter T1 connect, first output of transformer VT and the first relay S1's
First port connect, the first relay S1 the second port be connected with second output of transformer VT, the first relay S1
The first port and the first relay S1 the second port between be coil；
3rd port of the positive pole of the first power supply B1 and the first relay S1 connects, the 4th port of the first relay S1 with
First port of control chip C connects, and second port of control chip C and the negative pole of the first power supply B1 connect；Control chip C's

Port connects；Temperature detector TS is connected with the fifth port of control chip C；First port of the second relay S2 and the second relay
S2 the second port between be coil.
First heater circuit connects civil power by interface CN, and hand switch S3 is manual control switch；Hand switch S3 closes
During conjunction, civil power is the first heater strip H1 by the first temperature limiter T1 and temperature controller A1 and the first indicator lamp L1 powers, the first heating
Water in water tank is heated by silk H1, and the first indicator lamp L1 is bright；When hand switch S3 disconnects, the first heater circuit unpowered is returned
Road does not works；Temperature controller A1 is for detecting 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
During temperature 75 DEG C, the temperature detect switch (TDS) of temperature controller A1 disconnects, and makes the first heater circuit not work；First temperature limiter T1 is used for detecting water
Water temperature in case, the first temperature limiter T1 is normally closed, if temperature controller A1 fault, when water temperature reaches the second preset temperature 90 DEG C, first
Temperature limiter T1 disconnects, first port of the i.e. first temperature limiter T1 and second port of the first temperature limiter T1 separated, Yi Ji
4th port of the 3rd port of one temperature limiter T1 and the first temperature limiter T1 separated, makes the first heater circuit not work, with
Water temperature over-high in caisson causes safety problem；First temperature limiter T1 needs hand-reset after disconnecting.
When the interface CN of the first heater circuit connects civil power, civil power is carried out voltage and is converted into the first voltage by transformer VT
12V exports to the first relay S1, makes to close between the 3rd port of the first relay S1 and the 4th port of the first relay S1
Close, make to close between first port of control chip C and second port of control chip C, the first power supply B1, the first relay simultaneously
Forming power circuit between device S1 and control chip C, the first power supply B1 is that control chip C powers；Due to control chip C first
Close between port and second port of control chip C, make the 3rd port of control chip C and the 4th port of control chip C
Separated, make the separated of the 3rd port of the second relay S2 and the 4th port of the second relay S2, so that simultaneously
The loop of two heater circuits disconnects and cannot work.
When interface CN does not connect civil power, the first relay S1 does not has the power supply of the first voltage, the of the first relay S1
4th port of three ports and the first relay S1 separated, between the first power supply B1, the first relay S1 and control chip C
Loop power-off, the first power supply B1 cannot power for control chip C, first port of control chip C and the second of control chip C
Port separated, therefore close between the 3rd port of control chip C and the 4th port of control chip C, make the second relay
Close between 3rd port of S2 and the 4th port of the second relay S2, the loop energising work of the second heater circuit.
In second heater circuit, when the second relay S2 Guan Bi, second source B2 is that the second heater strip H2 powers, second
Water in water tank is heated by heater strip H2, and the second indicator lamp L2 is bright；Temperature detector TS is used for detecting the water temperature in water tank life
Becoming water temperature signal, when the water temperature in water tank reaches the first predetermined temperature 75 DEG C, temperature detector TS sends water temperature signal to controlling core
Piece C, control chip C control the interruption of the 3rd port of control chip C and the 4th port of control chip C according to water temperature signal
Open, so that the 4th port of the 3rd port of the second relay S2 and the second relay S2 is separated, therefore the second heater circuit
Loop disconnect cannot work；Second temperature limiter T2 is for detecting the water temperature in water tank, and the second temperature limiter T2 is normally closed, works as temperature detector
During TS fault, when water temperature reaches the second preset temperature 90 DEG C, the second temperature limiter T2 disconnects, first port of the i.e. second temperature limiter T2
Separated with second port of the second temperature limiter T2, and the of the 3rd port of the second temperature limiter T2 and the second temperature limiter T2
Four ports separated, makes the second heater strip H2 cannot power from second source B2, and the first heater circuit loop disconnects cannot work
Make, cause 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 technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection of the utility model claim
Within the scope of.
