Off-state.At this point, when short circuit occurs for the base stage of the first triode 112 and collector, the base stage sum aggregate of the first triode 112
Electrode conduction, the uncontrolled element 113 of the first triode 112 control.At this point, the second triode 118 is still by control element 113
Control.Thus, it is possible to pass through the disconnection of the second triode 118 or turn-on control circuit 110, and since cooking apparatus is in standby
State, control element 113 send low level to the second triode 118, and such second triode 118 is in an off state, and control
There is no electric current in circuit 110, i.e., no electric current is by the electromagnetic coil of computer heating control switch 119, and heater circuit 120 is in open circuit
State, heating element 122 do not heat.
When short circuit occurs for the base stage of the second triode 118 and collector, the base stage and collector of the second triode 118 are led
Logical, the uncontrolled element 113 of the second triode 118 controls.At this point, the one or two pole connected with the base stage of the second triode 118
Pipe 114 can be avoided the base stage that electric current flows to the first triode 112 from the base stage of the second triode 118, lead to the first triode
112 elements 113 switched on and uncontrolled control.Thus the cooking apparatus of present embodiment can be avoided in standby mode
Because short circuit occurs for the base stage and collector of the second triode 118, and it is switched on control circuit 110, and then lead to heating element
122 heat always, damage cooking apparatus.
Cooking apparatus according to the present utility model, in the use process of cooking apparatus, when the base stage of the first triode 112
Short circuit occurs for the base stage and collector that short circuit or the second triode 118 occurs with collector, can be avoided heating element 122 and holds
It is continuous to heat interior pot, protect cooking apparatus not to be heated the damage of element 122.
