Abstract
An electronic device having an exhaust opening configured to exhaust air outside, the electronic device includes a door part configured to close the exhaust opening when the electronic device has a predetermined temperature, wherein the door part is rotated based on the own weight of the door part and a wind pressure of the air taken in the electronic device and exhausted outside the electronic device, so that the exhaust opening is closed.
Claims19
An electronic device having an exhaust opening configured to exhaust air outside, the electronic device comprising:
- a door part configured to close the exhaust opening when the electronic device has a predetermined temperature,
- wherein the door part is rotated based on the own weight of the door part and a wind pressure of the air taken in the electronic device and exhausted outside the electronic device, so that the exhaust opening is closed.
A fire protecting mechanism of an electronic device having an exhaust opening configured to exhaust an air outside,
- wherein the fire protecting mechanism has a heat sensing member that is operated when a predetermined part inside the electronic device reaches a predetermined temperature, and thereby attachment of a door part to a top plate is broken;
- and
- the door part is rotated based on the own weight of the door part and a wind pressure of the air taken into the electronic device and exhausted outside the electronic device, so that the exhaust opening is closed.
An electronic device having an exhaust opening configured to exhaust air outside, the electronic device comprising:
- a door part configured to close the exhaust opening by rotating;
- and
- a line shaped member stretched along the substantially full width of the door part so as to keep the door part from rotating and keep the exhaust opening open;
- wherein the line shaped member is cut or extended in a length equal to or greater than a designated length so that the door part is rotated by the own weight of the door part and closes the exhaust opening.
A fire protecting mechanism of an electronic device having an exhaust opening configured to exhaust air outside, the electronic device comprising:
- a plurality of door parts configured to close the exhaust opening by rotating;
- and
- a plurality of line shaped members stretched along the substantially full 1 width of respective door parts so as to keep the door parts from rotating and keep the exhaust opening open;
- wherein the line shaped member is cut or extended in a length equal to or greater than a designated length so that the door part is rotated by the own weight of the door part and closes the exhaust opening;
- at least one door part among the plural door parts closes the exhaust opening and at least one other door part among the plural door parts maintains the exhaust opening open, when fire breaks out in the electronic device.
