Face the security risk of electric leakage.In addition, determining in super bath product structure design can not accomplish completely waterproof, make improper
In the case of, user is easy for water to be splashed into inside super bath, can equally cause security risk.
In addition, in existing fitment process the power outlet of super bath will not be reserved as other electric equipment products, and it is only
Reserved back panel wiring position, so that the method for the external earth leakage circuit-breaker of super bath is also difficult to realize, even if installation earth leakage protective is opened
It closes, it is considered however that reset issues when protection, and super bath is built-in in furred ceiling, once after earth leakage protective occurs, it is multiple
Position also needs to dismantle furred ceiling or buckle, the very bad operation for ordinary user, so existing super bath product is all not
With earth leakage protective device.
Utility model content
The technical problems to be solved in the utility model and the technical assignment of proposition be overcome existing super bath product be all without
The defect of earth leakage protective device provides a kind of super bath controller with earth leakage protective device.
In order to achieve the above objectives, the super bath controller with earth leakage protective device of the utility model, it is characterized in that including:
For the power circuit of entire control system power supply；
Control the load controller of each road load of super bath；

For the single-chip microcontroller of logic control, under single-chip microcontroller control, leakage current that sensor for detecting electric leakage detects
Amplify and be sent to single-chip microcontroller through electric-leakage detection circuit, MCU Instruction load controller closes all loads and exports and instruct failure
Indicating circuit issues failure alarm signal.
As optimization technique means: the load controller is relay or silicon-controlled.
As optimization technique means: the sensor for detecting electric leakage is ring current transformer or magnet ring, power supply zero
Line, power firestreak are also cross coiling on ring current transformer perhaps the magnet ring ring current transformer or magnet ring
There are coil, the coil connection electric-leakage detection circuit.

Be out of order alarm signal.
For the utility model without installing earth leakage circuit-breaker, controller carries creepage protection function；It can make to avoid super bath
With the danger that generation electric leakage in the process is caused；Leakage protection circuit using electronic control, detect electric leakage after close immediately it is defeated
Out, complete machine function can be restored by securely and reliably, re-powering.Solve lacking for existing super bath installation earth leakage circuit-breaker difficulty
Point, without reserved power outlet interface, without considering cabling inside super bath.
Detailed description of the invention
Fig. 1 is the system block diagram of the super bath controller with earth leakage protective device of the utility model；
Fig. 2 is that the sensor for detecting electric leakage of the utility model connects the circuit diagram of electric-leakage detection circuit.
Specific embodiment
The utility model is described further below in conjunction with Figure of description.
As shown in Figure 1, there is the super bath controller of earth leakage protective device to include: for this
For entire control system power supply power circuit,
The load controller of each road load of super bath is controlled,
For detecting the sensor for detecting electric leakage 1 of electric leakage,
For amplifying the electric-leakage detection circuit 2(of electric leakage signal referring to fig. 2),
The failure indicating circuit indicated when for leaking electricity,
For the single-chip microcontroller of logic control, under single-chip microcontroller control, leakage current that sensor for detecting electric leakage detects
Amplify and be sent to single-chip microcontroller through electric-leakage detection circuit, MCU Instruction load controller closes all loads and exports and instruct failure
Indicating circuit issues failure alarm signal.
Specifically, load controller is relay or silicon-controlled.Sensor for detecting electric leakage be ring current transformer or
Person's magnet ring, zero-power line, power firestreak are also cross ring current transformer perhaps magnet ring ring current transformer or magnet ring
On be wound with coil, coil connects electric-leakage detection circuit.Electric-leakage detection circuit includes amplifier and voltage follower circuit.Failure refers to
Show that circuit includes light-emitting diode display or/and buzzer.
The super bath controller with earth leakage protective device, when not leaking electricity on power supply line zero curve, firewire, ring current
The electric current sensed on the coil of mutual inductor or magnet ring is 0；Once it leaks electricity, the line of ring current transformer or magnet ring
Weak current will be sensed on circle, which passes through the processing of amplifying circuit, and small electric leakage signal is amplified and sent
