Abstract

An electronic apparatus includes: an apparatus chassis including therein an electronic board; a keyboard provided on a top of the apparatus chassis; and a fan device that includes a fan chassis and a blade part. The fan chassis includes a first air intake formed on a bottom surface thereof, a second air intake formed on a top surface thereof, and an air outlet formed on a side surface thereof. The blade part rotates inside the fan chassis. The fan device is arranged between a basal plate and a bottom surface of the keyboard inside the apparatus chassis. The basal plate includes a first inlet at a position overlapping the first air intake. The keyboard includes a second inlet that makes air pass through the keyboard in an up-down direction thereof. The electronic apparatus further includes a first water stop member that separates the first air intake from the electronic board.

Claims (65)

1. An electronic apparatus comprising:

an apparatus chassis including therein an electronic board;

a keyboard on a top of the apparatus chassis; and

a fan device that includes:

a fan chassis that includes a first air intake formed on a bottom surface of the fan chassis, a second air intake formed on a top surface of the fan chassis, and an air outlet formed on a side surface of the fan chassis; and

a blade part that rotates inside the fan chassis,

the fan device is between a basal plate of the apparatus chassis and a bottom surface of the keyboard, and is inside the apparatus chassis, wherein

the basal plate includes a first inlet at a position overlapping the first air intake,

the keyboard includes, at a position overlapping the second air intake, a second inlet that makes air pass through the keyboard, and

the electronic apparatus further comprises a first water stop member that surrounds at least a part of the first air intake, lies between the bottom surface of the fan chassis and an inner surface of the basal plate, and separates the first air intake from the electronic board;

the keyboard includes:

a plurality of key tops; and

a net-like frame that separates the key tops from each other, and

the second inlet includes a hole at a position overlapping a horizontal frame portion.

2. The electronic apparatus according to claim 1 , further comprising:

a second water stop member that surrounds at least a part of the second air intake, lies between the top surface of the fan chassis and the bottom surface of the keyboard, and separates the second air intake from the electronic board.

3. The electronic apparatus according to claim 1 , further comprising:

a cooling fin at the air outlet of the fan device; and

a third water stop member that lies at least between a bottom surface of the cooling fin and the inner surface of the basal plate.

4. The electronic apparatus according to claim 1 , wherein

the keyboard is fixed to the frame by a plurality of screws, and

at least a part of the second inlet is between adjacent screws among the plurality of screws.

5. The electronic apparatus according to claim 1 , wherein

the fan device further includes:

a motor part that rotates the blade part; and

a control board that controls the motor part,

the control board is attached to a back surface of the top surface of the fan chassis,

the second air intake is around the control board, and

the electronic apparatus further comprises a wall part between the control board and the second air intake.

6. The electronic apparatus according to claim 5 , wherein

the wall part is a standing wall that extends from the back surface, and

a bottom end of the wall part is near a surface of the control board.

7. The electronic apparatus according to claim 5 , wherein

a top plate forming the top surface of the fan chassis is made of metal, and

the wall part is formed of a resin component and is integrally molded with the top plate.

8. The electronic apparatus according to claim 5 , wherein

a top plate forming the top surface of the fan chassis is made of metal, and

the wall part is formed by bending an inner peripheral portion of the second air intake formed on the top plate.

9. The electronic apparatus according to claim 5 , wherein

a top plate forming the top surface of the fan chassis is made of metal, and

the wall part is formed by a side wall of a concave formed on the top plate.

10. An electronic apparatus comprising:

an apparatus chassis including therein an electronic board;

a keyboard on a top of the apparatus chassis; and

a fan device that includes:

a fan chassis that includes a first air intake formed on a bottom surface of the fan chassis, a second air intake formed on a top surface of the fan chassis, and an air outlet formed on a side surface of the fan chassis; and

a blade part that rotates inside the fan chassis,

the fan device is between a basal plate of the apparatus chassis and a bottom surface of the keyboard, and is inside the apparatus chassis, wherein

the basal plate includes a first inlet at a position overlapping the first air intake,

the keyboard includes, at a position overlapping the second air intake, a second inlet that makes air pass through the keyboard, and

the electronic apparatus further comprises a first water stop member that surrounds at least a part of the first air intake, lies between the bottom surface of the fan chassis and an inner surface of the basal plate, and separates the first air intake from the electronic board;

wherein a bottom plate forming the bottom surface of the fan chassis includes a bent part in which a peripheral portion of the first air intake is bent;

wherein the first water stop member is sandwiched between a tip surface of the bent part and the inner surface of the basal plate.

11. An electronic apparatus comprising:

an apparatus chassis including therein an electronic board;

a keyboard on a top of the apparatus chassis; and

a fan device that includes:

a fan chassis that includes a first air intake formed on a bottom surface of the fan chassis, a second air intake formed on a top surface of the fan chassis, and an air outlet formed on a side surface of the fan chassis; and

a blade part that rotates inside the fan chassis,

the fan device is between a basal plate of the apparatus chassis and a bottom surface of the keyboard, and is inside the apparatus chassis, wherein

the basal plate includes a first inlet at a position overlapping the first air intake,

the keyboard includes, at a position overlapping the second air intake, a second inlet that makes air pass through the keyboard, and

the electronic apparatus further comprises a first water stop member that surrounds at least a part of the first air intake, lies between the bottom surface of the fan chassis and an inner surface of the basal plate, and separates the first air intake from the electronic board;

wherein the inner surface of the basal plate includes a rib that extends to surround the first inlet;

wherein the first water stop member is sandwiched between the rib and a bottom plate forming the bottom surface of the fan chassis.
