[0018] According to the electronic device of the fourth aspect, the air sent by the air blowing device can be guided more reliably along the first direction.
[0019] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, like components are denoted by like reference numerals, and descriptions thereof will be omitted as appropriate. Furthermore, the embodiments do not limit the present disclosure, but are merely examples, and can be appropriately modified within the scope of the gist of the present disclosure.
[0020] 1, the electronic device 1 of this embodiment is, for example, a notebook personal computer (in other words, a laptop PC). The electronic device 1 includes a first unit 10 and a second unit 20. The second unit 20 is rotatably attached to the first unit 10 via a pair of hinges 30.
[0021] The first unit 10 has a first housing 11 and an input section 15 provided in the first housing 11. The first housing 11 has, for example, a substantially rectangular plate shape. The input section 15 is disposed on one surface intersecting the thickness direction of the first housing 11, and is configured with, for example, a keyboard and a touchpad that allow the user to perform input processing. Part of the configuration of the first unit 10 is omitted in FIG. 1.
[0022] The second unit 20 has a second housing 21 and a display device 22 provided in the second housing 21. The second housing 21 has, for example, a generally plate-like shape. The display device 22 is disposed on one surface of the second housing 21 that intersects with the thickness direction, and is configured, for example, with a generally rectangular liquid crystal display panel. The second unit 20 incorporates a central processing unit (CPU), a volatile storage device (RAM), a non-volatile storage device (ROM, SSD, etc.), a battery, etc. The non-volatile storage device stores an operating system (OS), various application programs, various data, etc. The central processing unit realizes various functions by reading the OS, application programs, and various data and executing arithmetic processing.
[0023] The pair of hinges 30 rotate the second unit 20 relative to the first unit 10 around a rotation axis extending along the longitudinal direction of the first housing 11, and can hold the second unit 20 at any angle relative to the first unit 10. For example, as shown in FIG. 1, the pair of hinges 30 can hold the electronic device 1 in an open state in which the second unit 20 forms any angle (e.g., approximately 120 degrees as shown in FIG. 1) relative to the first unit 10. The pair of hinges 30 can also hold the electronic device 1 in a closed state in which the second unit 20 forms an angle of approximately zero degrees relative to the first unit 10. In other words, the second unit is connected to the first unit 10 so as to be rotatable between a closed position P1 in which the display device 22 is close to and faces the first unit 10 and is in a closed state, and an open position P2 in which the display device 22 is angled relative to the first unit 10 and is away from the first unit 10 and is in an open state.
[0024] Next, the configuration of the first unit 10 will be described in more detail.
[0025] As shown in FIG. 2, the first unit 10 has a first housing 11 and a blower 12.
[0026] 2, the first housing 11 has a main body 111 and an exhaust path 40. The main body 111 has a first surface 112 and a second surface 113 that intersect with the thickness direction (e.g., the Z direction) of the main body 111, and a third surface 114 that intersects with the first surface 112 and the second surface 113. The input unit 15 is disposed on the second surface 113. In this embodiment, the third surface 114 constitutes one side surface of the first housing 11 in the short-side direction (e.g., the Y direction) and faces the second unit 20 that is positioned in the open position P2.
[0027] The blower 12 is configured, for example, by a centrifugal fan, and is arranged inside the main body 111 of the first housing 11, as shown in Fig. 2. The blower 12 has an air outlet 13, and sends air from the air outlet 13 along a first direction (for example, the Y direction) toward the second unit 20 located in the open position P2. In this embodiment, the air outlet 13 is arranged on the third surface 114 of the first housing 11.
[0028] As shown in FIG. 2 , the exhaust path 40 is provided in the first housing 11 and is disposed downstream of the blower 12 with respect to the flow of air sent by the blower 12. In this embodiment, the exhaust path 40 has a guide member 401 that is separate from the main body 111 of the first housing 11, and an auxiliary guide member 402. The guide member 401 has a first member 41, a second member 42, a third member 43, and a partition member 44, and is disposed at the end of the first housing 11 on the third surface 114 side to cover the antenna 14. The guide member 401 further has a fourth member 45, and has a generally C-shape as a whole. The auxiliary guide member 402 is configured as a separate member from the guide member 401. The antenna 14 is disposed between the partition member 44 and the fourth member 45.
[0029] The first member 41 is, for example, plate-shaped and extends along the first surface 112. The first member 41 has a guide surface 411 that guides the air sent by the blower 12 along the first direction Y. The end of the first member 41 on the second member 42 side in the first direction Y is inclined in a direction away from the first surface 112 along a second direction (for example, the Z direction) that intersects with the guide surface 411, and is curved and recessed slightly in the second direction Z in a direction away from the second surface 113.
[0030] The second member 42 is, for example, plate-shaped and is disposed in the first direction Y between the third surface 114 and the second unit 20 positioned in the open position P2. The second member 42 faces the second unit 20 positioned in the open position P2 and extends in the second direction Z from an end of the first member 41 farther from the blower device 12 in the first direction Y. The second member 42 is provided with a first exhaust hole 421 that penetrates the second member 42 in the first direction Y and communicates with the interior of the first housing 11 and the exterior of the first housing 11. In this embodiment, the first exhaust hole 421 is disposed at an end on the first member 41 side in the second direction Z.
[0031] The third member 43 is, for example, plate-shaped, extends from the second member 42 toward the main body 111 of the first housing 11, and faces the first member 41 in the thickness direction. More specifically, the third member 43 extends from an end of the second member 42 farthest from the first member 41 in the second direction Z, in a direction away from the first member 41 in the second direction Z as it moves away from the second member 42 in the first direction Y. In this embodiment, the third member 43 is curved and slightly recessed in the direction away from the first surface 112 in the second direction Z. The third member 43 is provided with a second exhaust hole 431 that penetrates the third member 43 in the thickness direction, communicates with the interior and exterior of the first housing 11, and is larger than the first exhaust hole 421. In this embodiment, the second exhaust hole 431 is located at the end of the third member 43 on the second member 42 side in the first direction Y.
[0032] The partition member 44 is disposed at an end of the interior of the exhaust path section 40 on the second member 42 side in the first direction Y and between the first member 41 and the third member 43 in the second direction Z. The partition member 44 divides the exhaust path provided inside the exhaust path section 40 into a first path 51 connected to the first exhaust hole 421 and a second path 52 connected to the second exhaust hole 431. In the present embodiment, the partition member 44 extends in the first direction Y from a portion of the second member 42 that is farther from the first member 41 in the second direction Z than the first exhaust hole 421 toward the blower device 12. When viewed in the second direction Z from the side of the second surface 113 of the first housing 11, the partition member 44 has substantially the same length in the first direction Y as the second exhaust hole 431.
[0033] 3, in this embodiment, the first exhaust hole 421 is configured so that its length W1 in the second direction Z is smaller than the length W2 of the second member 42 in the second direction Z from the first exhaust hole 421 to the third member 43. Furthermore, the first exhaust hole 421 is configured so that its length W1 in the second direction Z is smaller than the length W3 of the partition member 44 in the first direction Y.
[0034] The fourth member 45 extends in the first direction Y from the end of the third member 43 farther from the second member 42 in the first direction Y toward the main body 111 of the first housing 11.
[0035] As shown in Fig. 2, the auxiliary guide members 402 are arranged on both sides of the air outlet 13 of the blower device 12 in a third direction (for example, the X direction) that intersects with the first direction Y and the second direction Z. Only one of the auxiliary guide members 402 is shown in Fig. 2. Each auxiliary guide member 402 covers a gap surrounded by the first member 41, the second member 42, the third member 43, and the fourth member 45.
[0036] As shown in FIG. 4 , in this embodiment, a plurality of first exhaust holes 421 are provided in the second member 42, and a plurality of second exhaust holes 431 are provided in the third member 43. The plurality of first exhaust holes 421 are arranged at equal intervals along the third direction X. The plurality of second exhaust holes 431 are also arranged at equal intervals along the third direction X. Each first exhaust hole 421 is associated with one second exhaust hole 431. In other words, each first exhaust hole 421 and the corresponding second exhaust hole 431 are arranged next to each other on an imaginary line extending in the first direction Y. A rib 46 is provided between adjacent first exhaust holes 421. A partition wall 47 is provided between adjacent second exhaust holes 431.
[0037] Next, the relationship between the position of the second unit 20 relative to the first unit 10 and the first path 51 and the second path 52 will be described.
[0038] 2, when second unit 20 is located in open position P2, first exhaust hole 421 is smaller than second exhaust hole 431 and is covered by second unit 20. For this reason, the air sent from blower device 12 is mainly guided by partition member 44 to second path 52, flows diagonally upward to the right in FIG. 3 (direction of arrow A), and is exhausted from second exhaust hole 431 to the outside of first housing 11.
[0039] The inclination angle of the third member 43 relative to the second member 42 is set to an angle that prevents air exhausted to the outside of the first housing 11 through the second exhaust hole 431 from being blown directly onto the display device 22 of the second unit 20 located in the open position P2. In other words, the second exhaust hole 431 restricts the exhaust direction of the air sent from the blower device 12 to the direction of arrow A, and prevents the air exhausted from the second exhaust hole 431 from being blown directly onto the display device 22 of the second unit 20 in the open position P2 where the user positions the electronic device 1 when using the electronic device 1.
[0040] 2, when second unit 20 is located in closed position P1, second exhaust hole 431 is blocked by second unit 20, and air guided to second path 52 hits second unit 20 and bounces back. Therefore, air sent from blower 12 is mainly guided to first path 51, flows along the direction of arrow B in FIG. 3, and is exhausted from first exhaust hole 421 to the outside of first housing 11.
[0041] The electronic device 1 can achieve the following effects.
[0042] The electronic device 1 includes a first unit 10 and a second unit 20 having a display device 22. The first unit 10 includes a first housing 11, a blower 12 disposed inside the first housing 11, and an exhaust path 40 provided in the first housing 11. The exhaust path 40 includes a first member 41, a second member 42, a third member 43, and a partition member 44. The first member 41 has a guide surface 411 that guides air sent by the blower 12 along a first direction. The second member 42 extends in the second direction from an end of the first member 41 far from the blower 12 in the first direction and faces the second unit 20 in the open position P2. The third member faces the first member 41 and extends from an end of the second member 42 far from the first member 41 at an angle away from the first member 41 in the second direction as it moves away from the second member 42 in the first direction. The partition member 44 is disposed at an end of the exhaust path section 40 on the second member 42 side in the first direction and between the first member 41 and the third member 43 in the second direction, and extends along the first direction. The second member 42 is provided with a first exhaust hole 421. The third member 43 is provided with a second exhaust hole 431 that is larger than the first exhaust hole 421. That is, in the electronic device 1, air sent by the blower 12 is mainly exhausted to the outside of the first housing 11 through the first exhaust hole 421 when the second unit 20 is in the closed position P1, and mainly exhausted to the outside of the housing 11 through the second exhaust hole 431 when the second unit 20 is in the open position P2. Because the second exhaust hole 431 is provided in the third member 43 that is inclined with respect to the second member 42, it is possible to prevent the air sent from the blower 12 from being blown directly onto the display device 22 of the second unit 20 that is in the open position P2 for using the electronic device 1. That is, it is possible to prevent the display device 22 from being deteriorated by the heat exhausted from the inside of the first housing 11 to the outside. As a result, it is possible to realize an electronic device that can prevent the display device from being deteriorated by the air sent from the air blower.
[0043] First exhaust hole 421 is disposed at the end of second member 42 on the first member 41 side in the second direction, and the length of first exhaust hole 421 in the second direction is shorter than the length of second member 42 in the second direction from first exhaust hole 421 to third member 43. With this configuration, second exhaust hole 431 can be made larger than first exhaust hole 421, thereby realizing electronic device 1 that can more reliably prevent deterioration of display device 22 due to heat exhausted to the outside of first housing 11.
[0044] Second exhaust hole 431 is disposed at the end of third member 43 on the second member 42 side in the first direction, and the length of first exhaust hole 421 in the second direction is shorter than the length of partition member 44 in the first direction. With this configuration, second exhaust hole 431 can be made larger than first exhaust hole 421, thereby realizing electronic device 1 that can more reliably prevent deterioration of display device 22 due to heat exhausted to the outside of first housing 11.
[0045] The exhaust path portion 40 has auxiliary guide members 402 disposed on both sides of the air outlet 13 of the blower 12 in a third direction intersecting the first and second directions. With this configuration, the air sent by the blower 12 can be more reliably guided along the first direction.
[0046] The electronic device 1 can also be configured as follows.
[0047] First unit 10 can have any configuration including first housing 11, blower 12 disposed inside first housing 11, and exhaust path 40 provided in first housing 11.
[0048] The exhaust path section 40 is not limited to being configured as a separate body from the main body section 111 of the first housing 11, and may be configured as an integral part of the main body section 111.
[0049] The inclination angle of the third member 43 relative to the second member 42 can be set to any angle that prevents the air exhausted through the second exhaust hole 431 from being blown directly onto the display device 22 of the second unit 20 when the user is using the electronic device 1.
[0050] The second member 42, the third member 43, and the partition member 44 may be configured so that the second exhaust hole 431 is larger than the first exhaust hole 421. The first exhaust hole 421 may be provided at any position in the second member 42, and the second exhaust hole 431 may be provided at any position in the third member 43. If possible, the length of the first exhaust hole 421 in the second direction may be equal to or greater than the length of the second member 42 from the first exhaust hole 421 to the third member 43 in the second direction, or the length of the first exhaust hole 421 in the second direction may be equal to or greater than the length of the partition member 44 in the first direction.
[0051] It is sufficient that at least one first exhaust hole 421 and one second exhaust hole 431 are provided. For example, one first exhaust hole 421 extending along the third direction X may be provided in the second member 42, or one second exhaust hole 431 extending along the third direction X may be provided in the third member 43. In this case, a partition wall may be provided inside one first exhaust hole 421 to form a plurality of first exhaust paths 51. Similarly, a partition wall may be provided inside one second exhaust hole 431 to form a plurality of second paths 52.
[0052] The ribs 46 and the partition walls 47 may be omitted. Furthermore, the ribs 46 may be provided between all of the adjacent first exhaust holes 421, or the ribs 46 may be provided between some of the adjacent first exhaust holes 421. Similarly, the partition walls 47 may be provided between all of the adjacent second exhaust holes 431, or the partition walls 47 may be provided between some of the adjacent second exhaust holes 431.
[0053] The auxiliary guide member 402 can be omitted.
[0054] The auxiliary guide member 402 may be part of the main body 111 of the first housing 11, or may be a member that constitutes part of the guide member 401, or may be a member separate from the main body 111 and the guide member 401.
[0055] Any of the various embodiments or modifications described above can be combined appropriately to achieve the effects of each. In addition, combinations of embodiments, combinations of examples, or combinations of embodiments and examples are possible, and combinations of features from different embodiments or examples are also possible.
