The display section is configured such that only a portion of the cooling structure is formed into a projection projecting to the opposite side of the display surface of the display part.

Description

本発明は、冷却構造を有する画面一体型情報処理装置の薄型化技術に関する。   The present invention relates to a technology for reducing the thickness of a screen-integrated information processing apparatus having a cooling structure.

画面一体型パーソナル・コンピュータ等の画面一体型情報処理装置は、大画面かつ高性能なものが知られており、ユーザが、スリムでスタイリッシュなデザインを好むこともあり、装置（筐体）厚自体の薄型化が要求される。   Screen-integrated information processing devices such as screen-integrated personal computers are known for large screens and high performance, and users may prefer a slim and stylish design. Thinning is required.

この薄型化を実現するために、これまで、立方体の電源を単に装置内部に組み込んだり、ＡＣアダプタ化により電源を装置外部に取り出したり、電源を電源カバー（所定の厚みの板金）を取り外した状態で組み込み、装置の厚みを削減する手法があった。   In order to achieve this thinning, a cube power supply has been simply incorporated inside the device, or the power supply is taken out of the device by using an AC adapter, or the power supply cover (sheet metal with a predetermined thickness) is removed. There was a method to reduce the thickness of the device.

一方、画面一体型パーソナル・コンピュータ等の画面一体型情報処理装置には、ＣＰＵや電源等から発生する熱を冷却するためのファン等の冷却構造が設けれていることが多く、この冷却構造も装置厚自体の薄型化を実現する際には考慮しなくてはならない一要素となっている。   On the other hand, screen-integrated information processing apparatuses such as screen-integrated personal computers are often provided with a cooling structure such as a fan for cooling heat generated from a CPU, a power source, and the like. This is an element that must be taken into account when realizing a reduction in the thickness of the device itself.

ここで、関連技術として、ノート型パーソナル・コンピュータの内部の冷却ファンの前面にセット脚を利用して空洞を作って乱流を抑え、冷却効率を高め、全体的な薄型化を行う技術がある（例えば、特許文献１参照）。   Here, as a related technology, there is a technology that uses a set leg on the front face of a cooling fan inside the notebook personal computer to create a cavity to suppress turbulent flow, increase cooling efficiency, and reduce the overall thickness. (For example, refer to Patent Document 1).

特開２００１−７５６７７号公報JP 2001-75677 A

しかしながら、上記の関連技術では、ノート型パーソナル・コンピュータでなくセット脚を利用できないデスクトップ型の画面一体型パーソナル・コンピュータ等の装置厚の薄型化は困難である。
また、電源を単に装置内部に組み込むのでは、装置全体の厚みを電源関連部分の厚み以下の薄さとすることは困難であり、また、高級志向の製品層であるのでＡＣアダプタ化はユーザに好まれなく、また、電源カバーを取り外すと安全性が低下するおそれがある。 However, it is difficult for the above-described related art to reduce the thickness of a device such as a desktop-type personal computer with a screen that is not a notebook personal computer and cannot use a set leg.
In addition, if the power supply is simply incorporated inside the device, it is difficult to reduce the thickness of the entire device to be less than the thickness of the power supply related part. It is not uncommon, and there is a risk that safety will be reduced if the power cover is removed.

本発明の目的は、電源を装置内部に組み込む場合に、可能な限り装置厚の薄型化が実現された冷却構造を有する画面一体型情報処理装置を提供することにある。   An object of the present invention is to provide a screen-integrated information processing apparatus having a cooling structure in which the apparatus thickness is reduced as much as possible when a power source is incorporated in the apparatus.

本発明の冷却構造を有する画面一体型情報処理装置は、表示部と、該表示部を支持するスタンドを備え、前記表示部に電源と該電源の冷却構造とを内蔵する画面一体型情報処理装置であって、
前記表示部は、前記冷却構造の部分のみが前記表示部の表示面と反対側の面に凸部となることを特徴とする。 A screen-integrated information processing apparatus having a cooling structure according to the present invention includes a display unit and a stand that supports the display unit, and the display unit incorporates a power source and a cooling structure for the power source. Because
In the display unit, only a portion of the cooling structure is a convex portion on a surface opposite to the display surface of the display unit.

本発明によれば、冷却構造を有する画面一体型情報処理装置の装置内部に電源を組み込む場合に、可能な限り装置厚の薄型化を図ることができる。   According to the present invention, when a power source is incorporated in a screen-integrated information processing apparatus having a cooling structure, the thickness of the apparatus can be reduced as much as possible.

FIG.

以下、本発明の実施の形態について図面を参照して詳細に説明する。図１に示す本実施の形態における冷却構造を有する画面一体型情報処理装置としての画面一体型パーソナル・コンピュータ１０は、表示部２０と、スタンド３０とから構成されている。画面一体型パーソナル・コンピュータ１０は、一例であって、種々の情報処理装置であってよい。また、表示部２０は、液晶ディスプレイ（ＬＣＤ）パネル等の薄型表示パネルを備え、筐体により囲われており、画面一体型パーソナル・コンピュータ１０の本体が格納される。詳細な構成は後述する。なお、表示部２０とスタンド３０とは、ネジ等のヒンジ機構により接合され、スタンド３０により表示部２０が支持されている。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. A screen-integrated personal computer 10 as a screen-integrated information processing apparatus having a cooling structure in the present embodiment shown in FIG. 1 includes a display unit 20 and a stand 30. The screen-integrated personal computer 10 is an example, and may be various information processing apparatuses. The display unit 20 includes a thin display panel such as a liquid crystal display (LCD) panel, and is surrounded by a casing, and stores the main body of the screen-integrated personal computer 10. A detailed configuration will be described later. The display unit 20 and the stand 30 are joined by a hinge mechanism such as a screw, and the display unit 20 is supported by the stand 30.

スタンド３０は、例えば、スタンドリアカバーと、スタンドフロントカバーと、支柱と、接合部と、台座であるスタンドベースとを備えて構成されてよい。支柱の内部に設けられた回転機構によりスタンド３０を固定したまま表示部２０の角度を変えるためのチルト・スイベル動作が可能となる。   The stand 30 may include, for example, a stand rear cover, a stand front cover, a support column, a joint portion, and a stand base that is a pedestal. A tilt / swivel operation for changing the angle of the display unit 20 while the stand 30 is fixed can be performed by a rotation mechanism provided inside the column.

図２は、図１に示す画面一体型パーソナル・コンピュータ１０のＡ−Ａ‘面での断面図である。
表示部２０は、フロントカバー２１、ＬＣＤパネル２２、パネル−Ｍ／Ｂブラケット２３、スピーカ２４、ブロア（ＣＰＵファン）２５、Ｍ／Ｂ２６、ＨＤＤ２７、電源２８および電源ファン２９等から構成されている。基本的には既知の構成であり各構成の詳細な説明は省略する。
図２においては、表示部２０のうち概ねスタンド３０の高さ以上の部分は、それ以下の部分よりも厚みが薄くなっている（後述するようにその他にも薄くなっている部分は存在する）。すなわち、従来、電源２８を単に装置内部に組み込むのでは、表示部２０全体の厚みを電源関連部分の厚み以下の薄さとすることは困難であり、表示部２０全体の厚みが同一であり、表示部２０のうち概ねスタンド３０の高さ以上の部分も破線で示すようにそれ以下の部分と同一の厚みとなっていた。これを破線で示す部分と実図との差分だけ薄型化が実現されている。
従来、電源２８を単に装置内部に組み込む場合において、電源関連の構造を精査してみると、最も厚みをとるのが電源ファン２９の部分であり、逆にその他の部分は薄くできることが判明した。 2 is a cross-sectional view taken along the plane AA ′ of the screen-integrated personal computer 10 shown in FIG.
The display unit 20 includes a front cover 21, an LCD panel 22, a panel-M / B bracket 23, a speaker 24, a blower (CPU fan) 25, an M / B 26, an HDD 27, a power supply 28, a power supply fan 29, and the like. Basically, it is a known configuration, and detailed description of each configuration is omitted.
In FIG. 2, the portion of the display unit 20 that is substantially higher than the height of the stand 30 is thinner than the portion below that (there are other thinner portions as will be described later). . That is, conventionally, if the power supply 28 is simply incorporated in the apparatus, it is difficult to make the thickness of the entire display unit 20 smaller than the thickness of the power supply related part, and the entire thickness of the display unit 20 is the same. A portion of the portion 20 that is substantially higher than the height of the stand 30 also has the same thickness as the portion below it, as indicated by a broken line. Thinning is realized by the difference between the portion indicated by the broken line and the actual drawing.
Conventionally, when the power supply 28 is simply incorporated in the apparatus, the power supply-related structure has been scrutinized, and it has been found that the thickness of the power supply fan 29 is the largest and the other portions can be made thinner.

そこで、図３の電源断面図に示すように、従来、電源２８の後部に設けられる電源ファン２９の高さまで確保していた装置の厚み（破線で示す高さ）を、電源ファン２９の部分のみ従来と同一の厚み等とし、その他の部分は薄くする。
図３においては、板金で囲まれた電源２８の制御基板上のキャパシタと電源ファン２９との間には空気が流れるための少なくとも１ｍｍ程度の所定の空間が必要であるが、図３の構成では最低（ＭＩＮ）１．６４ｍｍ確保されている。
しかし、電源ファン２９の部分のみ従来と同一の厚み等で表示部２０の表示面と反対側の面に凸部となっていては、画面一体型パーソナル・コンピュータ１０を背面からユーザが見ると凸部が出っ張っており、スリムでスタイリッシュなデザインを好むユーザの嗜好を満足させることは困難である。そこで、この電源ファン２９の部分の凸部をユーザが視認しにくくすることで、凸部を目立たせなくすることが必要となる。 Therefore, as shown in the power supply cross-sectional view of FIG. 3, the thickness of the device (height indicated by the broken line) that has been conventionally secured up to the height of the power supply fan 29 provided at the rear portion of the power supply 28 is limited to the power supply fan 29 only. The thickness is the same as before, and the other parts are thin.
In FIG. 3, a predetermined space of at least about 1 mm is required for air to flow between the capacitor on the control board of the power supply 28 surrounded by the sheet metal and the power supply fan 29. In the configuration of FIG. The minimum (MIN) 1.64 mm is secured.
However, if only the portion of the power supply fan 29 has a convexity on the surface opposite to the display surface of the display unit 20 with the same thickness or the like as in the prior art, when the user looks at the screen-integrated personal computer 10 from the back, the convexity It is difficult to satisfy the tastes of users who prefer a slim and stylish design. Therefore, it is necessary to make the convex portions inconspicuous by making it difficult for the user to visually recognize the convex portions of the power supply fan 29.

図４は、図１に示す画面一体型パーソナル・コンピュータ１０の背面図である。
電源２８の後部に設けられる電源ファン２９部分のみ従来と同一の厚み等で凸部となっているが、破線で示すスタンド３０部分に当該凸部は隠れてユーザが視認しにくくなっている。
電源２８の一部は破線で示すスタンド３０に隠れていないが、図３において説明したとおり、電源２８の電源ファン２９が重なる（後部に設けられる）部分のみ従来と同一の厚み等で凸部となっているが、電源２８のうちその他の部分は厚みが薄くなっている。したがって、図２において説明したとおり、表示部２０のうち概ねスタンド３０の高さ以上の部分は、それ以下の部分よりも厚みが薄くなっていることに加えて、表示部２０のうち概ねスタンド３０の高さ以下の部分であっても電源２８の電源ファン２９が重なる（後部に設けられる）部分以外も厚みが薄くなっていてよい。
電源２８の電源ファン２９が重なる（後部に設けられる）部分のみを厚くし、スタンド３０の対面に位置づけることで電源ファン２９の厚みを目立たなくし、電源ファン２９以外の部分は薄くすることで装置厚自体の薄型化が実現されている。 4 is a rear view of the screen-integrated personal computer 10 shown in FIG.
Only the portion of the power supply fan 29 provided at the rear portion of the power supply 28 has a convex portion with the same thickness as the conventional one, but the convex portion is hidden in the stand 30 portion indicated by a broken line and is difficult for the user to visually recognize.
Although a part of the power supply 28 is not hidden by the stand 30 shown by the broken line, as explained in FIG. 3, only the part where the power supply fan 29 of the power supply 28 overlaps (provided at the rear part) has the same thickness and the like as before. However, the other portions of the power supply 28 are thin. Therefore, as described with reference to FIG. 2, the portion of the display unit 20 that is substantially higher than the height of the stand 30 is thinner than the portion of the display unit 20 that is less than the height of the stand 30. Even the portion below the height may be thinner than the portion where the power supply fan 29 of the power supply 28 overlaps (provided at the rear portion).
Only the part where the power supply fan 29 of the power supply 28 overlaps (provided at the rear part) is thickened, and the thickness of the power supply fan 29 is made inconspicuous by positioning it on the opposite side of the stand 30, and the part other than the power supply fan 29 is made thin. Thinning itself is realized.

なお、図２に示すように、電源２８の電源ファン２９が重なる（後部に設けられる）部分のみを厚くするのではなく、それ以外の部分である、ネジ等のヒンジ機構と対面する部分も厚くすることであってもよい。これにより、表示部２０とスタンド３０との空間（距離）の確保が確実にでき、チルト・スイベル動作等の際に表示部２０とスタンド３０とが接触すること等を確実に回避することができ、また、電源ファン２９の吸気のための空間の確保が確実にでき、さらに、チルト・スイベル動作等の際に表示部２０をユーザが下から手で保持する際の空間の確保が確実にできるという効果を奏する。   As shown in FIG. 2, not only the portion where the power supply fan 29 of the power supply 28 overlaps (provided at the rear portion) is thickened, but the other portion that faces the hinge mechanism such as a screw is also thickened. It may be to do. Thereby, the space (distance) between the display unit 20 and the stand 30 can be ensured, and the contact between the display unit 20 and the stand 30 during the tilt / swivel operation or the like can be reliably avoided. In addition, it is possible to ensure the space for intake of the power supply fan 29, and also to ensure the space when the user holds the display unit 20 from below during the tilt / swivel operation or the like. There is an effect.

なお、上述する実施の形態は、本発明の好適な実施の形態であり、本発明の要旨を逸脱しない範囲内において種々変更実施が可能である。   The above-described embodiment is a preferred embodiment of the present invention, and various modifications can be made without departing from the gist of the present invention.
