Description

この発明は、使用時に発熱するために筐体内に放熱用のファンが設けられた電気機器における、電源コードの格納装置に関するものである。   The present invention relates to a power cord storage device in an electrical apparatus in which a heat dissipating fan is provided in a casing to generate heat during use.

パーソナルコンピューター、プロジェクタ、IH調理具などの使用時に発熱する電気機器においては、筐体内に放熱用のファンが取り付けられている。
また、電気機器に付随する電源コードは、電気機器の筐体内に巻き込んで格納するようにすることが好ましいが、筐体内に電源コード巻き取り用のコードリールを取り付けるスペースがない場合は、コードを筐体内に巻き取って格納することができず、電気機器本体とは別に保管したり、持ち運ぶ必要がある。
そのために、携帯性を重視して筐体を小型化すると電源コードを巻き取ることができず、電源コードは別に持ち運ばなければならないこととなり、筐体の小型化が必ずしも携帯性の向上につながっていない。
In an electric device that generates heat when a personal computer, a projector, an IH cooking utensil, or the like is used, a heat radiating fan is attached in the casing.
In addition, it is preferable that the power cord attached to the electric device is wound and stored in the casing of the electric device. However, if there is no space for mounting the cord reel for winding the power cord in the casing, the cord is It cannot be wound up and stored in a housing, and must be stored or carried separately from the electrical equipment body.
For this reason, if the housing is downsized with emphasis on portability, the power cord cannot be taken up, and the power cord must be carried separately. Downsizing the housing does not necessarily improve portability. Not.

この発明は、筐体内に独立したスペースを確保する必要なく、筐体内に電源コードを格納でき、電気機器の携帯性を向上させることを課題とするものである。   An object of the present invention is to improve the portability of an electric device by storing a power cord in the housing without having to secure an independent space in the housing.

この発明は、放熱用ファンを有する電気機器において、前記放熱用ファンを囲んで電源コードのコードリールを設けて電源コードの格納装置を構成するものである。
前記コードリールの形状・構造に限定はない。例えば、通気口を有する筒体(請求項2)や、放熱用のファンを囲んで多数の柱を立設する構成が考えられる。
前記コードリールの装着部から電気機器筐体の外側との間には連通溝を形成することが好ましい(請求項3)。この連通溝は電源コードの配設の他に、放熱用ファンからの排気及び吸気に用いられる。したがって、この連通溝は複数設けることが好ましい。
電気機器の構造によっては、前記コードリールを電気機器の筐体から出入り可能に取り付ける(請求項4)ことにより、コードリールの取り扱いの利便性が向上する。
According to the present invention, in an electric apparatus having a heat dissipation fan, a power cord storage device is configured by providing a power cord cord reel around the heat dissipation fan.
There is no limitation on the shape and structure of the cord reel. For example, a structure in which a large number of pillars are erected around a cylindrical body having a vent (Claim 2) or a heat dissipation fan is conceivable.
It is preferable that a communication groove is formed between the cord reel mounting portion and the outside of the electric device casing. This communication groove is used for exhaust and intake from the heat dissipating fan in addition to the arrangement of the power cord. Therefore, it is preferable to provide a plurality of communication grooves.
Depending on the structure of the electrical device, the cord reel is attached so as to be able to enter and exit from the housing of the electrical device (claim 4), thereby improving the convenience of handling the cord reel.

なお、電源コードがコードリールに残ったままで電気機器を使用すると、所期の放熱効果が得られないおそれがある。そこで、電源コードがコードリールから完全に引き出されたときにのみ電気機器の主スイッチがONとなるように、補助スイッチを設けることが好ましい。
補助スイッチの構成としては、コードリールの内側に電源コードが完全に引き出されたときにのみ露出する接点を設け、コードリールの外側に設置されたバネ接点が電源コード引き出し時に前記接点に接触してONとなる構成や、コードリールの回転数をカウントしてスイッチをONとする構成などが考えられる。
また、簡便な方法としては、補助スイッチに代えて電源コードの基部に目印を付けておくこともできる。
Note that if an electric device is used with the power cord remaining on the cord reel, the desired heat dissipation effect may not be obtained. Therefore, it is preferable to provide an auxiliary switch so that the main switch of the electric device is turned on only when the power cord is completely pulled out from the cord reel.
The auxiliary switch consists of a contact that is exposed only when the power cord is completely pulled out inside the cord reel, and a spring contact that is installed outside the cord reel contacts the contact when the power cord is pulled out. A configuration in which the switch is turned on, a configuration in which the number of rotations of the cord reel is counted, and the switch is turned on are conceivable.
Further, as a simple method, a mark can be attached to the base of the power cord instead of the auxiliary switch.

この発明によれば、放熱用ファンを囲んでコードリールを設けたので、格別のスペースを確保することなく、電源コードを筐体内に格納することができる。そして、使用時には電源コードは引き出されるので、放熱ファンによる放熱は支障なく行われる。特に、請求項4の発明においてはコードリールと筐体外部との間の連通溝により空気の流通が促進されるので、一層効果的な放熱が行われる。   According to the present invention, since the cord reel is provided so as to surround the heat radiating fan, the power cord can be stored in the housing without securing a special space. Since the power cord is pulled out during use, heat radiation by the heat radiating fan is performed without any trouble. In particular, in the invention of claim 4, since the air flow is promoted by the communication groove between the cord reel and the outside of the casing, more effective heat dissipation is performed.

図1ないし図3はIH調理器における実施形態であり、筐体1の上部にIHヒーター2が設置してあり、その下方に放熱用ファン3が取り付けてある。この放熱用ファン3を囲んで電源コード4のコードリール5が設置してある。
前記コードリール5は円筒状であって周壁及び底壁に多数の通気孔6が設けてある。また、電源コードの自動巻き取りが出きるように、バネ力により回転するようにしてある。
1 to 3 show an embodiment of an IH cooker, in which an IH heater 2 is installed at the top of the housing 1 and a heat radiating fan 3 is attached below the IH heater 2. A cord reel 5 of a power cord 4 is installed around the heat radiating fan 3.
The cord reel 5 has a cylindrical shape and is provided with a number of vent holes 6 on the peripheral wall and the bottom wall. Further, the power cord is rotated by a spring force so that automatic winding of the power cord can be performed.

前記筐体1の底面には、前記コードリール5に沿って環状溝7が設けてあり、環状溝7と筐体外部とを連通する2本の連通溝8,9が反対向きに設けてある。前記連通溝8,9の一方は排気路、他方は流入路として機能すると共に、一方は電源コード4の配設溝として機能する。また、電源コードの配設溝となる連通溝の幅は、電源コードのプラグが収納できるものとしてある。
なお、コードリールの通気孔6を僅かに円周方向に傾斜させることにより、電源コードの配設される連通溝は外気の流入路として機能するようにすることが、電源コードの加熱が防止できるので好ましい。
前記筐体1の下部には小突起10が設けてあり、筐体1と接地面との間に空隙が形成され、この空隙から空気が流通できるようにしてある。
An annular groove 7 is provided on the bottom surface of the housing 1 along the cord reel 5, and two communication grooves 8 and 9 that communicate the annular groove 7 with the outside of the housing are provided in opposite directions. . One of the communication grooves 8 and 9 functions as an exhaust path, the other functions as an inflow path, and one functions as an arrangement groove of the power cord 4. In addition, the width of the communication groove serving as the power cord installation groove is set such that the power cord plug can be accommodated.
In addition, by slightly inclining the vent hole 6 of the cord reel in the circumferential direction, the communication groove in which the power cord is disposed can function as an outside air inflow path, and heating of the power cord can be prevented. Therefore, it is preferable.
A small protrusion 10 is provided at the lower portion of the housing 1, and a gap is formed between the housing 1 and the grounding surface so that air can flow from the gap.

この実施形態において、調理器を収納するときには、コードリール5に電源コード4を巻き取り、プラグを含めてケーシング内にコンパクトに収納することができる。したがって、調理器の携帯も容易となる。
調理器を使用するときには、電源コード4からコードリール5から完全に引き出す。完全に引き出したことが分かるように、電源コードの基部に目印を付けておくことが好ましい。
電源コードが完全に引き出されると、コードリール5の通気孔6が露出するので、コードリール内外は自由に空気が出入りすることができる。
In this embodiment, when the cooking device is stored, the power cord 4 can be wound around the cord reel 5 and can be stored compactly in the casing including the plug. Therefore, the cooking device can be easily carried.
When using the cooker, the power cord 4 is completely pulled out from the cord reel 5. It is preferable to mark the base of the power cord so that it can be completely pulled out.
When the power cord is completely pulled out, the air holes 6 of the cord reel 5 are exposed, so that air can freely enter and exit the inside and outside of the cord reel.

上記実施形態においては、コードリール下方に環状溝7を設け、外部との連通溝8,9を設けたので、外気は連通溝から環状溝を経て一層効率よく冷却ファン部分に導入され、排気も連通溝から効率よく排出されるので、高い冷却効率を得ることができる。   In the above embodiment, since the annular groove 7 is provided below the cord reel and the communication grooves 8 and 9 are provided to the outside, the outside air is introduced from the communication groove through the annular groove to the cooling fan portion more efficiently, and the exhaust air is also exhausted. Since it is efficiently discharged from the communication groove, high cooling efficiency can be obtained.

なお、連通溝と小突起の双方を設けることが空気の流通を容易にする点で好ましいが、連通溝のみ、小突起のみ(このときは小突起の高さを電源コード通過可能な高さとする)又はコードリールが配設される連通溝と小突起の組み合わせとすることもできる。   It is preferable to provide both the communication groove and the small protrusion from the viewpoint of facilitating the air flow, but only the communication groove and only the small protrusion (in this case, the height of the small protrusion is set to a height that allows the power cord to pass through ) Or a combination of a communication groove in which a cord reel is disposed and a small protrusion.

図4、図5はコードリール5を軸方向に移動可能に取り付けたものであり、電源コードの巻き取り時にコードリールが筐体から突出することにより、電源コードの巻き付け作業が容易となる。
図4はプロジェクタの例であり、コードリールと放熱ファンとが共に筐体から突出できるようにしてある。使用時には放熱ファンの格納スペースが露出する程度まで筐体から飛び出させる。そして、不使用時にはコードリールに電源コードを巻き付け、筐体1内へ収納する。
このような構成とする場合は、空気の流通用の溝などは不要である。
4 and 5 show the cord reel 5 attached so as to be movable in the axial direction. When the power cord is wound, the cord reel projects from the casing, so that the power cord can be easily wound.
FIG. 4 shows an example of a projector, in which both a cord reel and a heat radiating fan can protrude from the casing. When in use, the fan is popped out of the housing to the extent that the storage space for the heat dissipation fan is exposed. When not in use, the power cord is wound around the cord reel and stored in the housing 1.
In the case of such a configuration, an air circulation groove or the like is not necessary.

図5はノート型パソコンの例である。ノート型パソコンのように筐体が薄い器機においては、電源コードの収納スペースがそのまま空冷スペースとなる。   FIG. 5 shows an example of a notebook personal computer. In a device with a thin casing such as a notebook personal computer, the storage space for the power cord becomes an air cooling space as it is.

この発明は、電気機器の筐体内に、独立したスペースを必要とせずに電源コードを格納することができものであり、産業上の利用可能性を有するものである。   The present invention can store the power cord in the casing of the electric device without requiring an independent space, and has industrial applicability.
