Safety device of electric oven
A safety device of an electric oven is disclosed, which is provided to prevent a door from being open when a temperature inside an oven cavity is high. The safety device includes a hole provided in a front part of an oven cavity forming a cooking room therein; a latch protruding from an inner side of a door opening/closing the oven cavity, for being inserted into the hole when the door is closed; a rotation motor provided in an upper part of the oven cavity; a lever rotatably coupled with an axis of the rotation motor; and a temperature sensor measuring a temperature inside the oven cavity.
1. A safety device of an electric oven comprising:
a hole provided in a front part of an oven cavity forming cooking room therein;
a latch protruding from an inner side of a door opening/closing the oven cavity, for being inserted into the hole when the door is closed;
a rotation motor provided in an upper part of the oven cavity;
a lever rotatably coupled with an axis of the rotation motor; and
a temperature sensor measuring a temperature inside the oven cavity,
wherein the rotation motor is formed of a step motor.
2. The safety device as claimed in claim 1 , wherein the temperature sensor is provided inside the oven cavity.
3. The safety device as claimed in claim 1 , wherein the lever is formed in a plate shape having one end curved downwardly.
4. The safety device as claimed in claim 1 , further comprising a sensing part provided in an upper part of the oven cavity so as to sense the movement of the lever.
5. The safety device as claimed in claim 4 , wherein the sensing part includes a switch generating a rotation motor control signal by being in con contact with a lower part of the lever when the lever is rotated downwardly and coupled with the latch.
6. A safety device of an electric oven comprising:
a hole provided in front part of an oven cavity forming a cooking room therein;
a latch protruding from an inner side of a door opening/closing the oven cavity for being inserted into the hole when the door is closed;
a rotation motor provided in an upper part of the oven cavity;
a lever rotatably coupled with an axis of the rotation motor;
a temperature sensor measuring a temperature inside the oven cavity; and
a sensing part provided in an upper part of the oven cavity so as to sense the movement of the lever;
wherein the sensing part includes a switch generating a rotation motor control signal by being in contact with a lower part of the lever when the lever is rotated downwardly and coupled with the latch, and
wherein a protruding portion is provided in the lower par of the lever for being in contact with the switch of the sensing part.
7. A safety device of an electric oven comprising:
a hole provided in a front part of an oven cavity forming a cooking room therein;
a latch protruding from an inner side of a door opening/closing the oven cavity, for being inserted into the hole when the door is closed;
a rotation motor provided in an upper part of the oven cavity;
a lever rotatably coupled with an axis of the rotation motor;
a temperature sensor measuring a temperature inside the oven cavity;
a plate provided in an upper part of the oven cavity, having the rotation motor in a lateral part thereof; and
a stopper protruding from an upper end of the plate toward the lever so as to prevent the lever from being elevated above a predetermined angle.
8. The safety device as claimed in claim 7 , wherein the rotation motor is formed of a step motor.
9. The safety device as claimed in claim 7 , wherein the temperature sensor is provided inside the oven cavity.
10. The safety device as claimed in claim 7 , wherein the lever is formed in a plate shape having one end curved downwardly.
11. The safety device as claimed in claim 7 , further comprising a sensing part provided in an upper part of the oven cavity so as to sense the movement of the lever.
12. The safety device as claimed in claim 11 , wherein the sensing part includes a switch generating a signal of controlling the rotation motor, in a method of being in contact with a lower part of the lever when the lever is rotated downwardly and coupled with the latch.
13. The safety device as claimed in claim 12 , wherein a protruding portion is provided in the lower part of the lever for being in contact with the switch of the sensing part.
