Description
Technical Field
The utility model relates to a safety work monitoring device for electrical apparatus, in particular to a safety device for an electrical cooking oven.
background
Both U.S. patent No. 05380985(graham) and canadian patent application No. 05380985(vaillancourt) propose a device to temporarily disable a range after a user leaves the area for a predetermined period of time. The range is then automatically re-enabled when the user first returns, and then needs to be manually reset on all subsequent returns. Canadian patent application 02152015(vaillancourt) also uses a voltage detection sensor to determine the heating rate of the furnace.
Japanese patent laid-open No.03-091643 (Kiyomi, Yoshiro) proposes a hood fan used in combination with an electric heating or cooking device. If the range hood fan detects the presence of a flame, both the range hood fan and the electrical heating and cooking device are automatically turned off.
The device can not realize better alarm and safety control for the common electric furnace and electric oven.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a safety device of an electric cooking oven, which can monitor the electric oven and the electric oven cooking equipment, and can cut off the power supply of the electric oven and the electric oven cooking equipment when the heating elements of the electric oven and the electric oven cooking equipment work and are unsupervised in a specified time; once smoke triggers the smoke alarm to alarm, the smoke alarm also cuts off the power supply of the electric stove and the electric oven cooking equipment.
In order to solve the technical problem, the utility model adopts the following technical scheme:
The utility model provides a safety device of electric cooking stove, includes relay auto-lock protection device, relay drive arrangement, electric cooking stove pass through relay auto-lock protection device and be connected with power supply socket electricity, relay drive arrangement is connected with relay auto-lock protection device electricity, relay drive arrangement control relay auto-lock protection device, relay drive arrangement is multichannel the control unit, relay drive arrangement is equipped with current induction switch the control unit, takes the motion detection switch the control unit of timer, manual timer, smog detection switch the control unit.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its beneficial effect is:
By means of the different control parts of the multi-channel control unit, the heating elements of the electric oven and the electric oven cooking device can be cut off when working and without supervision in a specified time. Once smoke triggers the smoke alarm to alarm, the smoke alarm also cuts off the power supply of the electric stove and the electric oven cooking equipment.
Further, the utility model discloses an optimization scheme is:
The relay self-locking protection device is provided with a safety device input plug and a safety device output socket, the safety device input plug is electrically connected with the power supply socket, and the safety device output socket is electrically connected with the electric cooking stove.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
referring to fig. 1-3, a safety device of an electric cooking stove, the safety device 10 is composed of a relay self-locking protection device and a relay driving device 16; the electric cooking stove is electrically connected with the power supply socket 11 through the relay self-locking protection device, the relay driving device 16 is electrically connected with the relay self-locking protection device, the relay driving device 16 controls the relay self-locking protection device, the relay driving device 16 is a multi-channel control unit, and the relay driving device 16 is provided with a current induction switch control unit 20, a motion detection switch control unit 18 with a timer, a manual timer 17 and a smoke detection switch control unit 19.
By means of the different control parts provided by the multi-channel control unit, it is possible to cut off the power supply to the electric oven and electric oven cooking device 13 when the heating elements of the electric oven and electric oven cooking device 13 are active and unsupervised for a prescribed time. It also cuts off power to the electric and electric oven cooking apparatus 13 once smoke has triggered the smoke alarm.
The relay self-locking protection device is provided with a safety device input plug 12 and a safety device output socket 15, the safety device input plug 12 is electrically connected with a socket 11 of a power supply line, and the safety device output socket 15 is electrically connected with an electric plug 14 of the electric cooking stove.
through setting up safety device input plug 12, safety device output socket 15, make things convenient for the safety device to be connected with the power electricity, make things convenient for the safety device to be connected with electric cooking stove electricity simultaneously.
As shown in fig. 3, CS is a switch controlled by current detection. It is set to "on" when the electric oven and electric oven cooking device 13 is in operation and set to off when not in operation. The MS is a switch controlled by a motion detector together with a timer. When no one is near the electric and electric oven cooking device 13 and the timer delay time is reached, it is set to the off state. The MTS is a manual timer 17 switch so the user can manually set the required time delay. SS is a switch controlled by a smoke alarm. It is set "on" when there is no alarm and is in an off state when a smoke alarm is triggered. RB is a reset button. RL-1, RL-2 and RL-3 are relays. RL-1 is controlled by MS, MTS, SS, and RB. RL-1 together with CS controls RL-3. When the system is in the protection state, RL-3 and RL-2 form a self-locking state.
