Switch, it is characterised in that：The door switch of refrigerator doors is series at the power input of high-voltage electrostatic field generating means, and the high pressure is quiet
Electric field generation device is additionally provided with output current detection circuit and the feedback circuit of the current value, ice is fed back to refrigerator master controller
Case master controller connection control high-voltage electrostatic field generating means.
Wherein, refrigerator is provided with door switch, which feeds back enabling signal not only as sensor to master controller,
But the power input of high voltage electrostatic device is connected on, and when the door is open, the power supply of direct cutoff high electrostatic equipment, in master
Controller still is able to provide protection to user when breaking down.
Further, it is described to refrigerator master controller feed back the feedback circuit of the current value for current detection sensor or/and
For arc-detection sensor.
In this way, feedback of the master controller according to current detection sensor on the generating means of high-voltage electrostatic field, judges output electricity
Stream is either with or without generation significant changes.If output current occurs substantially to increase in a short time, may be occur short circuit or
Shock phenomenon, the output of master controller horse back cutoff high, and send corresponding acousto-optic hint, it is ensured that the safety of personnel and product.
In addition, master controller judges whether occur electric arc in refrigerator, such as according to electric arc detection sensor on the generating means of high-voltage electrostatic field
There is then horse back cutoff high output, and send corresponding acousto-optic hint in electric arc, it is ensured that the safety of personnel and product.
Above-mentioned electric current and arc protection function can be used alone, further, can also be with other safeguard measures or break-make
Electric installation connects, and multiple protective is formed together as door cut-offs electric protection；Refrigerator inside lighting lamp circuit is such as connected, is opened in headlamp
Qi Shi（When i.e. refrigerator doors are opened）Master controller is transmitted signals to, is closed automatically by main controller controls high-voltage electrostatic field generating means
It closes, it is ensured that the safety of personnel and product.
The signal source of current detection sensor or/and arc-detection sensor is all inside the generating means of high-voltage electrostatic field
Output current feedback circuit.Current detecting is detection low-frequency current, such as the current upper limit value of setting is 10mA, and normal operation is electric
Stream only has 3 mA, if electric current flies up this limit value more than 10mA and will trigger alarm.Arc-detection is then that detection is high
Frequency electric current equally sets 10mA, and normal operating current is 3 mA, detects the current impulse of high frequency occur, although being not achieved
The limit value of 10mA, such as peak value only have 5 ~ 6mA, it can be determined that there is electric arc.
Compared with prior art, the beneficial effects of the utility model are：Refrigerator door open-close is not only as sensor to master
Controller feeds back enabling signal, but is connected on the power input of high-voltage electrostatic field generating means, when the door is open, directly cuts
The power supply of disconnected high voltage electrostatic device still is able to provide protection to user when master controller breaks down.In addition, master controller connects
It receives current detection sensor or/and is fed back for the signal of arc-detection sensor, broken down in door switch or main control circuit
When, high-voltage electrostatic field generating means still can be closed, so as to more effectively protect the safety of user.
