Description

本発明は、面状発熱体を利用した電気採暖装置に関するものである。   The present invention relates to an electric warming device using a planar heating element.

従来この種の電気採暖装置は、図４および図５に示すように本体１内部に本体前面より輻射熱を放射するように面状発熱体２を垂直に設置して輻射暖房を行ない、さらに面状発熱体２の上下位置に通気可能な空間と後方に一定の間隔３を設けて遮熱板４を設け、面状発熱体２の裏面の空気を暖めて自然対流暖房を行っている。なお図中、５は暖房能力の切換スイッチ、６は面状発熱体２に対する保護ガードである（例えば、特許文献１参照）。   Conventionally, as shown in FIG. 4 and FIG. 5, this type of electric warming apparatus performs radiant heating by installing a planar heating element 2 vertically so as to radiate radiant heat from the front surface of the main body. A heat shield plate 4 is provided with a space that allows ventilation in the upper and lower positions of the heating element 2 and a predetermined interval 3 in the rear, and natural convection heating is performed by heating the air on the back surface of the planar heating element 2. In the figure, 5 is a heating capacity changeover switch, and 6 is a protective guard for the sheet heating element 2 (see, for example, Patent Document 1).

しかしながら、前記従来の構成では、面状発熱体２を加熱して輻射暖房と対流暖房の両方を行っているので、自然対流による暖房性能を向上させるためには面状発熱体２の発熱能力を上げなければならず輻射温度も上昇し、本体前面のパネル面温度が高くなるため、不用意に人が触れないような対策を講じなければならないという課題を有していた。   However, in the conventional configuration, since the sheet heating element 2 is heated to perform both radiant heating and convection heating, the heating capacity of the sheet heating element 2 is improved in order to improve the heating performance by natural convection. Since the radiation temperature has to be raised and the panel surface temperature on the front surface of the main body is increased, there is a problem that it is necessary to take measures to prevent people from touching carelessly.

また、逆に本体前面のパネル面温度の上昇を抑えると自然対流による暖房性能が得られにくくなるという課題を有していた。さらに暖房能力の切換も面状発熱体２の発熱線の通電箇所を切換えて行なっているため、本体１の前面に臨む面状発熱体２の輻射の分布が変わるという課題を有していた。
特開平７−３１８０７９号公報 On the other hand, if the rise in the panel surface temperature on the front surface of the main body is suppressed, the heating performance by natural convection is difficult to obtain. Furthermore, since the heating capacity is switched by switching the energization location of the heating wire of the planar heating element 2, there is a problem that the radiation distribution of the planar heating element 2 facing the front surface of the main body 1 changes.
JP 7-318079 A

The temperature is set to a level that is safe even if a person touches the panel, and the heating element for convection heating can be set to a temperature suitable for convection heating without being affected by the temperature of the radiation surface of the heat radiating panel. It is configured for natural convection heating in which air flowing in from the air inlet of the apparatus main body is heated and warm air is discharged from the exhaust outlet of the warming apparatus main body. As a result, the surface heating element for radiant heating and the heating element for convection heating can set their own temperatures so that radiant heating and convection heating can be performed efficiently, respectively. The temperature of the radiating surface is set to a temperature that does not cause any problems even if a person touches it without affecting each other, and the heating temperature of the other heating element for natural convection heating is set to the radiating surface temperature of the radiating panel. It is possible to increase without being influenced by, and the heating performance by natural convection can be improved.

第２の発明は、特に第１の発明の対流暖房用の発熱体を複数で構成し、前記複数の発熱体の通電切換を行う運転切換スイッチを設けることにより、対流暖房用の発熱体の能力を切換スイッチにて調節することが可能となり、使用環境や使用状況に合わせてきめ細かい温度調節をすることができ、使用環境や使用状況に適した対流暖房能力を容易に選択することができる。   According to the second invention, in particular, the convection heating heating element of the first invention is constituted by a plurality of elements, and an operation changeover switch for switching the energization of the plurality of heating elements is provided.

第４の発明は、第１の発明〜第３の発明のいずれかにおける対流暖房用の複数の発熱体に、それぞれ独立して放熱フィンを取付けることにより、対流暖房用の発熱体から発生する熱エネルギーを効率よく放熱することができるとともに、前記発熱体において一方が通電し、他方が通電していない通電の有無により各発熱体の長さに膨張差が生じるが、それぞれの発熱体に放熱フィンをそれぞれ別個に設けているので、通電された発熱体の熱膨張に応じて放熱フィンも膨張することとなり、１枚の放熱フィンでもって各発熱体を連結したことにより通電の有無による温度差で生じる放熱フィンと発熱体の摺動等で生じていた異音の発生を解消することができる。   According to a fourth aspect of the present invention, the heat generated from the heating element for convection heating is provided by independently attaching a radiation fin to the plurality of heating elements for convection heating according to any one of the first to third inventions.

第６の発明は、第５の発明の風洞の排出口を採暖装置本体の後面に設けた構成とすることにより、採暖装置本体の前面に暖気を放出するための開口部を設ける必要がないので、採暖装置本体の前面を平面化することが可能となり、デザイン性を高めることができるのはもちろん、採暖装置本体前面の放熱パネルから放出される熱により暖められた輻射暖気と対流暖房用の発熱体で暖められた暖気を分散することが可能となり、採暖装置本体の前面の温度上昇を抑制することができる。   According to the sixth aspect of the present invention, since the air tunnel outlet of the fifth aspect is provided on the rear surface of the warming device body, there is no need to provide an opening for releasing warm air on the front surface of the warming device body.

以上のように構成された電気採暖装置について、以下その動作、作用を説明する。まず、電源スイッチ２６を操作して電源を投入すると、面状発熱体２２が通電されるとともに、対流暖房用の発熱体２５ａ、２５ｂへの分岐通電回路３２が通電待機状態になる。続いて運転切換スイッチ２７の操作により対流暖房用の複数の発熱体２５ａ、２５ｂへの通電が行なわれる。すなわち、運転切換スイッチ２７は通常、接点ｃに投入されＯＦＦにされており、接点ｂに投入すると発熱体２５ａ、接点ａに投入すると発熱体２５ａ、２５ｂが通電されて対流暖房の運転とその対流暖房の能力切替えも行なわれる。   About the electric warming apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. First, when the power is turned on by operating the power switch 26, the sheet heating element 22 is energized and the branch energization circuit 32 to the heating elements 25a, 25b for convection heating enters an energization standby state. Subsequently, the operation of the operation changeover switch 27 energizes the plurality of heating elements 25a and 25b for convection heating. That is, the operation switch 27 is normally turned on at the contact point c and turned off. When the contact switch b is turned on, the heating element 25a is energized, and when the contact point a is turned on, the heating elements 25a and 25b are energized. The heating capacity is also switched.

従って、輻射暖房は面状発熱体２３に加熱された放熱パネル２２の前面から図１に矢印で示すように熱放射されて行われるとともに、放熱パネル２２の放熱面に使用者が触れても問題にならない程度の温度に保たれる。一方、対流暖房は発熱した発熱体２５ａ、２５ｂにより通風路２５内が温度上昇し、図１に矢印で示すように吸気口３０より外気が流入して発熱体２５ａ、２５ｂに加熱されて暖気となり排出口３１より部屋に排出されて行われる。   Therefore, radiant heating is performed by radiating heat from the front surface of the heat radiating panel 22 heated by the planar heating element 23 as indicated by arrows in FIG. 1, and even if the user touches the heat radiating surface of the heat radiating panel 22, there is a problem. It is kept at a temperature that does not become low. On the other hand, in the convection heating, the temperature in the ventilation path 25 rises due to the heat generating elements 25a and 25b that generate heat, and as shown by arrows in FIG. 1, outside air flows from the inlet 30 and is heated by the heat generating elements 25a and 25b to become warm air. It is discharged from the discharge port 31 to the room.

特に本実施の形態では、面状発熱体２３と対流暖房用の発熱体２５ａ、２５ｂを別個に設けているので、面状発熱体２３に加熱された放熱パネル２２の輻射面の温度を人が触れても問題のない程度の温度に設定しながら効率よく輻射暖房が行え、一方の対流暖房用の発熱体２５ａ、２５ｂは、放熱パネル２２の輻射面の温度に影響されることなく、対流暖房に適した発熱温度に上げることが可能となり、自然対流による暖房性能を向上することができる。   In particular, in the present embodiment, since the sheet heating element 23 and the convection heating elements 25a and 25b are provided separately, the temperature of the radiation surface of the heat dissipation panel 22 heated by the sheet heating element 23 can be adjusted by a person. Radiant heating can be performed efficiently while setting the temperature so that there is no problem even if touched, and one of the convective heating elements 25a and 25b is not affected by the temperature of the radiation surface of the heat radiating panel 22 and is convectively heated. It is possible to raise the heat generation temperature suitable for the heating, and the heating performance by natural convection can be improved.

そして、更に面状発熱体２３は電源スイッチ２６により、対流暖房用の発熱体２５ａ、２５ｂは電源スイッチ２６に通電制御される分岐通電回路３２を介した運転切替スイッチ２７により、それぞれ独立して通電できるようにしているので、上記したように輻射暖房と対流暖房がそれぞれ効率よく行えることはもちろん、電源スイッチ２６の１箇所から電源供給が行える利点を有する。   Further, the sheet heating element 23 is energized independently by the power switch 26, and the heating elements 25a and 25b for convection heating are energized independently by the operation switch 27 via the branch energization circuit 32 controlled to energize the power switch 26. As described above, it is possible to efficiently perform radiant heating and convection heating as described above, and it has an advantage that power can be supplied from one place of the power switch 26.

また本実施の形態では、対流暖房用の発熱体２５ａ、２５ｂは、その通電本数を運転切替スイッチ２７にて選択することにより、対流暖房の能力を調節することが可能となり、使用環境や使用状況に合わせてきめ細かい温度調節をすることもできる。   In the present embodiment, the convection heating heating elements 25a and 25b can be adjusted in the convection heating capacity by selecting the number of energizations with the operation changeover switch 27. It is possible to adjust the temperature precisely according to the conditions.

また、本実施の形態では面状発熱体２３は電源スイッチ２６により、対流暖房用の発熱体２５ａ、２５ｂは電源スイッチ２６に通電制御される分岐通電回路３２を介した運転切替スイッチ２７により通電できるようにし、選択した対流暖房用の発熱体２５ａ、２５ｂの暖房能力にかかわらず常に面状発熱体２３に通電するようにしているので、発熱体２５ａ、２５ｂのＯＦＦを含む切換に関係なく常に輻射暖房が行なわれることになり、使用者に採暖装置が動作していることを容易に認識させることができる。   In the present embodiment, the sheet heating element 23 can be energized by the power switch 26 and the heating elements 25a and 25b for convection heating can be energized by the operation changeover switch 27 via the branch energization circuit 32 controlled to energize the power switch 26. In this way, the planar heating element 23 is always energized regardless of the heating capacity of the selected heating element 25a, 25b for convection heating, so that radiation is always performed regardless of switching including the OFF of the heating elements 25a, 25b. Heating is performed, and the user can easily recognize that the heating device is operating.

なお、上記実施の形態における面状発熱体２３は放熱パネル２２と、遮熱板２４は面状発熱体２３と図１に示すように僅少隙間を設けて配置しているが、僅少隙間をなくして密着して設けても良いものである。   In the above embodiment, the planar heating element 23 and the heat shield 24 are arranged with a small gap as shown in FIG. 1, but the clearance gap is eliminated. May be provided in close contact with each other.

図３は、本発明の実施の形態３における電気採暖装置の部分断面側面図を示すものである。２８は下部を吸気口３０に、上部を排出口３１ａに連通させて採暖装置本体２１内に縦方向に設けられた風洞で、内部下方に対流暖房用の発熱体２５ａ、２５ｂが設置されている。２９ａ、２９ｂは対流暖房用の発熱体２５ａ、２５ｂの熱を放熱するための放熱フィンで、図３に点線で示すように１枚のフィンで上下の発熱体を一体に連結するのではなく、対流暖房用の各発熱体２５ａ、２５ｂにそれぞれ独立して固定している。暖気の排出口３１ａは、採暖装置本体２１の後面上部に設け、採暖装置本体２１の前面上部に使用者が触れても問題にならない程度の温度になるように構成している。 (Embodiment 2)
FIG. 3 is a partial cross-sectional side view of the electric warming device according to Embodiment 3 of the present invention. Reference numeral 28 denotes a wind tunnel vertically provided in the warming device main body 21 with the lower portion communicating with the intake port 30 and the upper portion communicating with the discharge port 31a. Heating elements 25a and 25b for convection heating are installed below the interior. . 29a and 29b are radiating fins for radiating the heat of the heating elements 25a and 25b for convection heating. Instead of connecting the upper and lower heating elements integrally with one fin as shown by the dotted line in FIG. 3, The heating elements 25a and 25b for convection heating are fixed independently. The warm air outlet 31a is provided at the upper rear surface of the warming device main body 21, and is configured to have a temperature that does not cause a problem even if the user touches the upper front surface of the warming device main body 21.

以上のように構成された電気採暖装置について、以下その動作、作用を説明する。電気採暖装置の電源スイッチ２６、運転切換スイッチ２７を操作して面状発熱体２３、対流暖房用の発熱体２５ａ、２５ｂに通電する。そして、実施の形態１で説明したようにして輻射暖房が行われ、一方、対流暖房用の発熱体２５ａ、２５ｂが高温になると、図３に矢印で示すように採暖装置本体２１の下部の吸気口３０より冷気が流入し、風洞２８内を通過して対流暖房用の発熱体２５ａ、２５ｂで加熱された放熱フィン２９ａ、２９ｂにて暖められ暖気になる。さらに暖められた暖気は、風洞２８に沿ってさらに上昇し、採暖装置本体２１の後面上部の排出口３１ａより部屋に放出される。   About the electric warming apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. By operating the power switch 26 and the operation switch 27 of the electric warming device, the sheet heating element 23 and the heating elements 25a and 25b for convection heating are energized. Then, radiant heating is performed as described in the first embodiment. On the other hand, when the convection heating heating elements 25a and 25b reach a high temperature, as shown by arrows in FIG. Cold air flows from the opening 30 and passes through the wind tunnel 28 and is warmed by the radiating fins 29a and 29b heated by the heating elements 25a and 25b for convection heating. The warmed air further rises along the wind tunnel 28 and is discharged into the room from the discharge port 31a at the upper rear surface of the warming device main body 21.

特に本実施の形態では、発熱体２５ａ、２５ｂのそれぞれに独立して放熱フィン２９ａ、２９ｂを取付けているので、通電された発熱体の熱膨張にあわせて放熱フィンも膨張することになり、通電した発熱体と通電していない発熱体とが図３に点線で示す１枚の放熱フィンで連結された際に、前記した通電の有無による発熱体の温度差により生じる放熱フィンと発熱体の摺動等で生じていた異音の発生を解消することができる。   In particular, in the present embodiment, since the radiation fins 29a and 29b are independently attached to the heating elements 25a and 25b, the radiation fins expand in accordance with the thermal expansion of the energized heating elements. When the heat generating element that is not energized and the heat generating element that is not energized are connected by a single heat dissipating fin indicated by the dotted line in FIG. It is possible to eliminate the generation of abnormal noise caused by movement or the like.

また本実施の形態では、採暖装置本体２１の内部に対流暖房用の発熱体２５ａ、２５ｂを内蔵した風洞２８を設置することにより、吸気口３０から効率よく冷気が流入し、対流暖房用の発熱体２５ａ、２５ｂで加熱された放熱フィン２９ａ、２９ｂで暖められて暖気となり、効率よく排出口３１より放出されることになり、自然対流による暖房性能を向上することができる。   Further, in the present embodiment, by installing the wind tunnel 28 containing the convection heating heating elements 25a and 25b in the warming device main body 21, the cool air efficiently flows from the intake port 30, and the convection heating heat is generated. The heat radiation fins 29a, 29b heated by the bodies 25a, 25b are warmed by the heat radiation fins 29a, 29b, and are efficiently discharged from the discharge port 31, so that the heating performance by natural convection can be improved.

そして、風洞２８を通過した暖気の排出口３１を採暖装置本体２１の後面上部に設けているので、採暖装置本体２１の前面に暖気を放出するための開口部を設ける必要がないので放熱パネル２２の平面に続き前面部全体を平面化することが可能となり、デザイン性を高めることができるのはもちろん、採暖装置本体２１の前面の放熱パネル２２から放出される熱により暖められた暖気と対流暖房用の発熱体２５ａ、２５ｂで加熱された放熱フィンにより暖められた暖気を分散することが可能となり、採暖装置本体２１の前面上部の温度上昇を抑制することができる。   Since the warm air discharge port 31 that has passed through the wind tunnel 28 is provided at the upper rear surface of the warming device main body 21, there is no need to provide an opening for releasing warm air on the front surface of the warming device main body 21. It is possible to flatten the entire front portion following the flat surface, and it is possible to improve the design, as well as warm air and convection heating that are warmed by heat released from the heat radiating panel 22 on the front surface of the warming device main body 21. It becomes possible to disperse the warm air warmed by the heat radiation fins heated by the heating elements 25a, 25b, and to suppress the temperature rise at the upper front of the warming device main body 21.

以上のように本発明にかかる電気採暖装置は、放熱パネルの温度を使用者が触れても問題ない程度の温度に設定しながら対流による暖房性能を向上すること可能となるので、居住空間の壁面に埋設した暖房装置などの用途にも適用できる。   As described above, the electric heating device according to the present invention can improve the heating performance by convection while setting the temperature of the heat radiating panel to a level that does not cause any problem even if the user touches it, so that the wall surface of the living space It can be applied to uses such as a heating device embedded in the wall.
