Description

本発明は、暖房機に関する。 The present invention relates to a heater.

従来、シーズヒータなどの発熱部と、発熱部を収容する放熱部とを有し、放熱部から放熱される熱で空調対象室の空気を暖める暖房機が知られている。例えば特許文献1には、直線的な管状のヒータが、放熱部に形成された管状の空間に配置されることが開示されている。このようなヒータの上下端には、端子が設けられている。端子は、配線を介して基板と接続されている。 Conventionally, there is known a heater having a heat generating portion such as a sheathed heater and a heat radiating portion accommodating the heat radiating portion, and heating the air in the air-conditioned room with the heat radiated from the heat radiating portion. For example, Patent Document 1 discloses that a linear tubular heater is arranged in a tubular space formed in a heat radiating portion. Terminals are provided at the upper and lower ends of such a heater. The terminals are connected to the board via wiring.

中国実用新案第204187710号明細書China Utility Model No. 204187710

配線は、発熱部に対する耐熱性を考慮して設計される必要がある。上述したとおり端子が複数箇所に点在する場合、配線自体の耐熱性および配線に対する遮熱のための構成を複数箇所において考慮する必要がある。これは、部品点数の増加や、配線の高耐熱化、筐体内の収容空間の制約に繋がると共に、対流を阻害して暖房効率を低下させる要因となる。 The wiring needs to be designed in consideration of heat resistance to the heat generating part. When the terminals are scattered at a plurality of locations as described above, it is necessary to consider the heat resistance of the wiring itself and the configuration for heat shielding the wiring at the plurality of locations. This leads to an increase in the number of parts, a high heat resistance of the wiring, a restriction on the accommodation space in the housing, and a factor that hinders convection and lowers the heating efficiency.

本発明はこのような事情を考慮してなされたもので、暖房効率を向上させることができる暖房機を提供することを目的とする。 The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a heater capable of improving heating efficiency.

本発明に係る暖房機は、上述した課題を解決するために、U字形状を有し、両端に端子を有する少なくとも一の発熱部と、前記発熱部を収容し、前記発熱部の熱で内部に空気の対流を生じさせる筐体と、を備える。 In order to solve the above-mentioned problems, the heater according to the present invention accommodates at least one heat generating portion having a U shape and having terminals at both ends and the heat generating portion, and is internally heated by the heat of the heat generating portion. It is provided with a housing that causes air convection.

以下の説明において、「前(前面)」、「後(背面)」、「上」、「下」、「右」、および「左」は、図1から図8における定義に従う。また、上下方向は、暖房機1の設置時における上下方向に対応する。前後方向および左右方向は、暖房機1の設置時における水平方向に対応する。 In the following description, "front (front)", "rear (rear)", "top", "bottom", "right", and "left" follow the definitions in FIGS. 1-8. Further, the vertical direction corresponds to the vertical direction when the heater 1 is installed. The front-rear direction and the left-right direction correspond to the horizontal direction when the heater 1 is installed.

暖房機1は、放熱部10と、発熱部20と、筐体30と、遮熱板50と、固定具60と、を主に有する。暖房機1は、発熱部20の熱で筐体30の内部に空気の対流を生じさせることにより、空調対象室の空気を暖める。 The heater 1 mainly includes a heat radiating unit 10, a heat generating unit 20, a housing 30, a heat shield plate 50, and a fixture 60. The heater 1 warms the air in the air-conditioned room by causing convection of air inside the housing 30 by the heat of the heat generating portion 20.

放熱部10は、一の発熱部20を内部に収容し、発熱部20の熱を外表面から放熱する。放熱部10は、アルミニウム合金のダイカスト成形品である。放熱部10は、発熱部収容部11と、フィン12と、を有する。発熱部収容部11は、前後方向に沿う面方向を有する右面13と、右面13に左右方向で対向し前後方向に沿う面方向を有する左面14と、を有する。発熱部20は、この右面13および左面14の間に収容される。フィン12は、右面13および左面14から略垂直に突出し、設置時における上下方向に延びる(上下方向に沿う面方向を有する)複数のフィン12である。フィン12は、前後方向に沿って、例えば略等間隔で配列される。放熱部10は、固定具60で支持されるための貫通孔15(図6)を有する。貫通孔15は、前後方向の中心を対称に2箇所形成され、フィン12内を左右方向に貫通して形成される。 The heat radiating unit 10 accommodates one heat generating unit 20 inside, and dissipates the heat of the heat radiating unit 20 from the outer surface. The heat radiating unit 10 is a die-cast molded product of an aluminum alloy. The heat radiating unit 10 has a heat generating unit accommodating unit 11 and fins 12. The heat generating portion accommodating portion 11 has a right surface 13 having a surface direction along the front-rear direction, and a left surface 14 facing the right surface 13 in the left-right direction and having a surface direction along the front-rear direction. The heat generating portion 20 is housed between the right surface 13 and the left surface 14. The fins 12 are a plurality of fins 12 that protrude substantially vertically from the right surface 13 and the left surface 14 and extend in the vertical direction (have a surface direction along the vertical direction) at the time of installation. The fins 12 are arranged along the front-rear direction, for example, at substantially equal intervals. The heat radiating portion 10 has a through hole 15 (FIG. 6) for being supported by the fixture 60. The through holes 15 are formed at two points symmetrically with respect to the center in the front-rear direction, and are formed so as to penetrate the inside of the fin 12 in the left-right direction.

放熱部10は、上下方向に沿って配列された複数の放熱部であり、上段放熱部10a、中段放熱部10b、および下段放熱部10cを有する。例えば、上段放熱部10a、中段放熱部10b、および下段放熱部10cは、フィン12の形状、フィン12の寸法、および隣接するフィン12の間隔を含み、略同一の外形を有する。 The heat radiating unit 10 is a plurality of heat radiating units arranged along the vertical direction, and has an upper heat radiating unit 10a, a middle heat radiating unit 10b, and a lower heat radiating unit 10c. For example, the upper heat radiating section 10a, the middle heat radiating section 10b, and the lower heat radiating section 10c have substantially the same outer shape, including the shape of the fin 12, the dimensions of the fin 12, and the distance between the adjacent fins 12.

発熱部20は、図7に示すように、両端に端子22を有する、例えばシーズヒータである。発熱部20は、主に前後方向に延び、長さ方向の略中心に曲げ部21を有するU字形状を有する。発熱部20は、端子22を前方に向って露出して各放熱部10の発熱部収容部11(内部)に収容されている。具体的には、発熱部20は、U字形状の状態で、放熱部10のダイカスト成形時に内部に鋳込まれることにより、放熱部10と一体成形される。端子22は、配線26を介して後述する基板25に接続されている。配線26は、例えば、銅線をビニールで被覆して絶縁したビニール線である。なお、図7においては、1つの発熱部20のみが基板25と接続される例が示されているが、複数の発熱部20(本実施形態においては3つ)がそれぞれ配線26を介して共通の基板25、または収容空間55内に配置される別途の基板に接続されている。 As shown in FIG. 7, the heat generating portion 20 is, for example, a sheathed heater having terminals 22 at both ends. The heat generating portion 20 has a U-shape that extends mainly in the front-rear direction and has a bent portion 21 at a substantially center in the length direction. The heat generating portion 20 exposes the terminal 22 toward the front and is housed in the heat generating portion accommodating portion 11 (inside) of each heat radiating portion 10. Specifically, the heat generating portion 20 is integrally molded with the heat radiating portion 10 by being cast inside during die casting of the heat radiating portion 10 in a U-shaped state. The terminal 22 is connected to the substrate 25, which will be described later, via the wiring 26. The wiring 26 is, for example, a vinyl wire obtained by coating a copper wire with vinyl to insulate it. In addition, although FIG. 7 shows an example in which only one heat generating portion 20 is connected to the substrate 25, a plurality of heat generating portions 20 (three in the present embodiment) are common via the wiring 26, respectively. It is connected to the substrate 25 of the above or another substrate arranged in the accommodation space 55.

暖房機1は、3個の(複数の)発熱部20を有する。これらの発熱部20は、端子22の方向(端子22の突出方向、筐体30内の上下左右前後方向における位置)を揃えて筐体30に収容されている。具体的には、3個の発熱部20は、端子22が前方、折り曲げ部21が後方に位置し、上方視において略重なり合うように筐体30に収容されている。 The heater 1 has three (plural) heating units 20. These heat generating portions 20 are housed in the housing 30 with the directions of the terminals 22 (the protruding direction of the terminals 22 and the positions in the housing 30 in the vertical, horizontal, front-back directions) aligned. Specifically, the three heat generating portions 20 are housed in the housing 30 so that the terminals 22 are located in the front and the bent portions 21 are located in the rear so as to substantially overlap each other in the upward view.

筐体30は、放熱部10を収容し、暖房機1の外郭をなす。筐体30は、前板31と、後板32と、下板33と、上カバー34と、左右パネル35と、を有する。前板31、後板32、下板33、上カバー34、および左右パネル35は、例えば冷間圧延鋼板や溶融亜鉛めっき鋼板などの薄鋼板からなる。筐体30は、これらの部材により、発熱部20の熱で内部に空気の対流を生じさせるための構造を成している。 The housing 30 accommodates the heat radiating unit 10 and forms the outer shell of the heater 1. The housing 30 has a front plate 31, a rear plate 32, a lower plate 33, an upper cover 34, and left and right panels 35. The front plate 31, the rear plate 32, the lower plate 33, the upper cover 34, and the left and right panels 35 are made of thin steel plates such as cold-rolled steel plates and hot-dip galvanized steel plates. The housing 30 has a structure for causing air convection inside by the heat of the heat generating portion 20 by these members.

前板31は、暖房機1の前面に沿って配置される。前板31は、表示部37と、操作部38と、前側取っ手39aと、を有する。表示部37は、暖房機1の運転状態や操作内容を表示する、例えば液晶表示パネルである。操作部38は、暖房機1の電源の入れ切れや、運転内容の指示を受け付ける。前側取っ手39aは、表示部37の上方に配置され、ユーザによる暖房機1の移動に用いられる。後板32は、暖房機1の後面に沿って配置される。後板32は、前側取っ手39aと前後方向において対になる位置に、後側取っ手39bを有する。前板31および後板32は、前後方向で対向する一対の内壁31a、32a(図6)を有する。 The front plate 31 is arranged along the front surface of the heater 1. The front plate 31 has a display unit 37, an operation unit 38, and a front handle 39a. The display unit 37 is, for example, a liquid crystal display panel that displays the operating state and operation contents of the heater 1. The operation unit 38 receives instructions for turning on / off the power of the heater 1 and operating contents. The front handle 39a is arranged above the display unit 37 and is used for the user to move the heater 1. The rear plate 32 is arranged along the rear surface of the heater 1. The rear plate 32 has a rear handle 39b at a position paired with the front handle 39a in the front-rear direction. The front plate 31 and the rear plate 32 have a pair of inner walls 31a and 32a (FIG. 6) facing each other in the front-rear direction.

下板33は、暖房機1の下面に沿って配置される。下板33は、前板31、後板32、および遮熱板50のベースとなる。下板33は、暖房機1内に空気を取り入れる空気入口40を有する。下板33は、暖房機1を移動するために用いられる一対のキャスター付脚41を下方の前後方向において対になる位置に有する。 The lower plate 33 is arranged along the lower surface of the heater 1. The lower plate 33 serves as a base for the front plate 31, the rear plate 32, and the heat shield plate 50. The lower plate 33 has an air inlet 40 that takes in air into the heater 1. The lower plate 33 has a pair of legs 41 with casters used for moving the heater 1 in a paired position in the lower front-rear direction.

上カバー34は、暖房機1の上面に沿って上方に配置される。上カバー34は、グリル42と、金網43と、パネル取付具45と、を有する。グリル42は、空気入口40から取り入れられ、暖房機1内を隣接するフィン12間を流路として下から上に向かって流れる空気の出口となる空気出口46を有する。金網43は、空気出口46を塞ぐように、グリル42の下方に配置される。パネル取付具45は、金網43の下方に配置され、一対の遮熱板50間に前後に架設された枠部材である。パネル取付具45は、左右パネル35を固定するための構造である爪部45aを左右の枠面に有する。 The upper cover 34 is arranged upward along the upper surface of the heater 1. The upper cover 34 has a grill 42, a wire mesh 43, and a panel attachment 45. The grill 42 has an air outlet 46 that is taken in from the air inlet 40 and serves as an outlet for air that flows from the bottom to the top with the adjacent fins 12 in the heater 1 as a flow path. The wire mesh 43 is arranged below the grill 42 so as to block the air outlet 46. The panel attachment 45 is a frame member arranged below the wire mesh 43 and erected back and forth between the pair of heat shield plates 50. The panel mounting tool 45 has claws 45a, which are structures for fixing the left and right panels 35, on the left and right frame surfaces.

左右パネル35は、暖房機1の左右側面に沿ってそれぞれ配置される。左右パネル35は、放熱部10からの高温の熱に対するユーザの安全性を確保するため、放熱部10を覆って遮蔽する。これにより、暖房機1の内部はユーザにより視認されない。 The left and right panels 35 are arranged along the left and right side surfaces of the heater 1. The left and right panels 35 cover and shield the heat radiating unit 10 in order to ensure the safety of the user against the high temperature heat from the heat radiating unit 10. As a result, the inside of the heater 1 is not visible to the user.

左右パネル35は、上端に内面方向の折返し(図示せず)を有する。左右パネル35の上端は、この折り返しをパネル取付具45の爪部45aに引っ掛けることにより固定されている。左右パネル35の下端は、下板33にネジ止めされることにより固定されている。また、左右パネル35の前後端は、前板31および後板32にそれぞれ係止されている。左右パネル35の中央部36aは、外縁部36bに対して放熱部10から離れるように膨出した形状を有している。これにより左右パネル35は、遮熱板50とは非接触に固定されていると共に、放熱部10との間に一定の隙間が設けられている。このため、左右パネル35は、過剰な温度上昇が抑制されている。 The left and right panels 35 have an inner surface folded back (not shown) at the upper end. The upper ends of the left and right panels 35 are fixed by hooking the folded back onto the claw portion 45a of the panel fixture 45. The lower ends of the left and right panels 35 are fixed by being screwed to the lower plate 33. The front and rear ends of the left and right panels 35 are locked to the front plate 31 and the rear plate 32, respectively. The central portion 36a of the left and right panels 35 has a shape that bulges away from the heat radiating portion 10 with respect to the outer edge portion 36b. As a result, the left and right panels 35 are fixed in non-contact with the heat shield plate 50, and a certain gap is provided between the left and right panels 35 and the heat radiating portion 10. Therefore, the temperature rise of the left and right panels 35 is suppressed.

遮熱板50は、例えば薄鋼板からなり、放熱部10からの熱を、前板31および後板32の一対の内壁31a、32aと放熱部10との間で遮熱する。すなわち、遮熱板50は、前側遮熱板50aと、後側遮熱板50bと、を有する一対の遮熱板50である。図6に示すように、前側遮熱板50aは、前板31の内壁31aと放熱部10の前端18aとの間に配置される。後側遮熱板50bは、後板32の内壁32aと放熱部10の後端18bとの間に配置される。遮熱板50は、少なくとも放熱部10が配置される上下方向の範囲に設けられる。これにより、遮熱板50は、前板31または後板32の内壁31a、32aと遮熱板50との間の収容空間55に設けられる基板25や配線26類などの電子部品と放熱部10との間を仕切り、放熱部10と電子部品とを隔離する。各放熱部10から露出した複数の端子22は、遮熱板50から突出し、収容空間55内に位置する。遮熱板50は、ベースとなる下板33に下部が固定され、遮熱板50の上方に位置するパネル取付具45に上部が固定される。これにより、遮熱板50およびパネル取付具45は、暖房機1の内部骨格を構成している。 The heat shield plate 50 is made of, for example, a thin steel plate, and heat from the heat radiating portion 10 is shielded between the pair of inner walls 31a and 32a of the front plate 31 and the rear plate 32 and the heat radiating portion 10. That is, the heat shield plate 50 is a pair of heat shield plates 50 having a front side heat shield plate 50a and a rear side heat shield plate 50b. As shown in FIG. 6, the front heat shield plate 50a is arranged between the inner wall 31a of the front plate 31 and the front end 18a of the heat radiating portion 10. The rear heat shield plate 50b is arranged between the inner wall 32a of the rear plate 32 and the rear end 18b of the heat radiating portion 10. The heat shield plate 50 is provided at least in the vertical range in which the heat radiating portion 10 is arranged. As a result, the heat shield plate 50 includes electronic components such as the substrate 25 and wiring 26 provided in the accommodation space 55 between the inner walls 31a and 32a of the front plate 31 or the rear plate 32 and the heat shield plate 50, and the heat radiating portion 10. The heat radiating unit 10 and the electronic component are separated from each other. The plurality of terminals 22 exposed from the heat radiating portions 10 project from the heat shield plate 50 and are located in the accommodation space 55. The lower part of the heat shield plate 50 is fixed to the lower plate 33 which is the base, and the upper part is fixed to the panel fixture 45 located above the heat shield plate 50. As a result, the heat shield plate 50 and the panel fixture 45 form the internal skeleton of the heater 1.

固定具60は、例えば薄鋼板からなり、放熱部10を支持し、前後方向に亘って一対の遮熱板50に両端65、75が固定(架設)される。具体的には、固定具60は、右固定具61と、左固定具71と、を有し、これら一対の固定具60により放熱部10を左右側面で支持し、遮熱板50に固定される。 The fixture 60 is made of, for example, a thin steel plate, supports the heat radiating portion 10, and both ends 65 and 75 are fixed (installed) to a pair of heat shield plates 50 in the front-rear direction. Specifically, the fixture 60 has a right fixture 61 and a left fixture 71, and the heat radiating portion 10 is supported on the left and right side surfaces by the pair of fixtures 60 and fixed to the heat shield plate 50.

右固定具61は、放熱部10の右面13側で放熱部10を支持し、右面13側で一対の遮熱板50に固定される。右固定具61は、前後方向に略直線的な形状を有し、遮熱板50に固定される両端65を有する。右固定具61は、右固定具側ボルト孔67と、肉抜き部68と、を有する。右固定具側ボルト孔67は、右固定具61、左固定具71および放熱部10を連結するためのボルト81が貫通する孔であり、貫通孔15に対応する位置に設けられる。肉抜き部68は、固定具60から遮熱板50へ熱を伝わりにくくする。 The right fixture 61 supports the heat radiating portion 10 on the right side 13 side of the heat radiating portion 10, and is fixed to the pair of heat shield plates 50 on the right side 13 side. The right fixture 61 has a substantially linear shape in the front-rear direction, and has both ends 65 fixed to the heat shield plate 50. The right fixture 61 has a right fixture side bolt hole 67 and a lightening portion 68. The right fixture side bolt hole 67 is a hole through which the bolt 81 for connecting the right fixture 61, the left fixture 71, and the heat radiating portion 10 penetrates, and is provided at a position corresponding to the through hole 15. The lightening portion 68 makes it difficult for heat to be transferred from the fixture 60 to the heat shield plate 50.

左固定具71は、左面14側で放熱部10を支持し、左面14側で一対の遮熱板50に固定される。左固定具71は、基部72と、垂れ下がり部73と、を有する。基部72は、前後方向に略直線的な形状を有し、遮熱板50に固定される両端75を有する。垂れ下がり部73は、基部72の両端75から中心寄りに前後方向の端部を有し、基部72から垂れ下がる形状を有する。垂れ下がり部73は、左固定具側ボルト孔77と、肉抜き部78と、を有する。左固定具側ボルト孔77は、右固定具側ボルト孔67と同様の作用を有し、貫通孔15に対応する位置に設けられる。肉抜き部78は、肉抜き部68と同様の作用を有し、垂れ下がり部73のうち、左固定具側ボルト孔77が形成される領域以外の可能な限り広い範囲で形成される。 The left fixture 71 supports the heat radiating portion 10 on the left surface 14 side, and is fixed to the pair of heat shield plates 50 on the left surface 14 side. The left fixture 71 has a base 72 and a hanging portion 73. The base portion 72 has a substantially linear shape in the front-rear direction, and has both ends 75 fixed to the heat shield plate 50. The hanging portion 73 has an end portion in the front-rear direction toward the center from both ends 75 of the base portion 72, and has a shape of hanging from the base portion 72. The hanging portion 73 has a left fixture side bolt hole 77 and a lightening portion 78. The left fixture side bolt hole 77 has the same function as the right fixture side bolt hole 67, and is provided at a position corresponding to the through hole 15. The lightening portion 78 has the same function as the lightening portion 68, and is formed in the widest possible range other than the region where the left fixture side bolt hole 77 is formed in the hanging portion 73.

固定具60は、放熱部10の個数に対応する複数の固定具である。各固定具60は、各放熱部10を支持し、一対の遮熱板50に固定される。すなわち、固定具60は、上段放熱部10aを支持する一対の上段固定具60aと、中段放熱部10bを支持する一対の中段固定具60bと、下段放熱部10cを支持する一対の下段固定具60cと、を有する。上段固定具60a、中段固定具60b、および下段固定具60cは、形状、寸法において略同一である。 The fixture 60 is a plurality of fixtures corresponding to the number of heat radiating portions 10. Each fixture 60 supports each heat radiating portion 10 and is fixed to a pair of heat shield plates 50. That is, the fixture 60 includes a pair of upper fixtures 60a that support the upper heat radiating portion 10a, a pair of middle fixtures 60b that support the middle heat radiating portion 10b, and a pair of lower fixtures 60c that support the lower heat radiating portion 10c. And have. The upper fixing tool 60a, the middle fixing tool 60b, and the lower fixing tool 60c are substantially the same in shape and size.

各一対の固定具60(上段固定具60a、中段固定具60b、下段固定具60c)は、放熱部10(上段放熱部10a、中段放熱部10b、下段放熱部10c)を挟み込み連結(固定)することにより、放熱部10と一体となった放熱ユニット80を形成する。図6に示すように、放熱ユニット80においては、放熱部10は、右面13側に配置される右固定具61と、左面14側に配置される左固定具71とにより挟み込まれている。左固定具側ボルト孔77、貫通孔15および右固定具側ボルト孔67をボルト81が順次貫通し、このボルト81が右固定具61側でナット82により締められることにより、放熱ユニット80は、一体化されている。 Each pair of fixtures 60 (upper fixture 60a, middle fixture 60b, lower fixture 60c) sandwiches (fixes) the heat radiating portion 10 (upper heat radiating portion 10a, middle radiating portion 10b, lower radiating portion 10c). As a result, the heat dissipation unit 80 integrated with the heat dissipation unit 10 is formed. As shown in FIG. 6, in the heat radiating unit 80, the heat radiating portion 10 is sandwiched between the right fixture 61 arranged on the right surface 13 side and the left fixture 71 arranged on the left surface 14 side. The bolt 81 sequentially penetrates the left fixture side bolt hole 77, the through hole 15, and the right fixture side bolt hole 67, and the bolt 81 is tightened by the nut 82 on the right fixture 61 side, so that the heat dissipation unit 80 is subjected to. It is integrated.

ボルト81とナット82による連結構造は、スペーサ83と、ワッシャー84と、を有する。スペーサ83は、ボルト81の外側に配置された状態で貫通孔15内に挿入される。スペーサ83は、放熱部10の貫通孔15の長さよりも長く、貫通孔15の端部15a、15bから若干量突出している。ワッシャー84は、貫通孔15の右側端部15aと右固定具61の内面61aとの間、および貫通孔15の左側端部15bと左固定具71の内面71aとの間に配置される。ボルト81、ナット82およびスペーサ83は、互いに同様の熱伝導率を有する材料(例えばステンレス鋼)からなる。ワッシャー84は、熱伝導率が低く、耐熱性を有する材料(例えばテフロン(登録商標))または接触面積を減らして熱伝導を抑えたステンレス鋼製のウェーブワッシャーからなる。 The connecting structure of the bolt 81 and the nut 82 has a spacer 83 and a washer 84. The spacer 83 is inserted into the through hole 15 in a state of being arranged outside the bolt 81. The spacer 83 is longer than the length of the through hole 15 of the heat radiating portion 10, and slightly protrudes from the ends 15a and 15b of the through hole 15. The washer 84 is arranged between the right end portion 15a of the through hole 15 and the inner surface 61a of the right fixture 61, and between the left end portion 15b of the through hole 15 and the inner surface 71a of the left fixture 71. The bolt 81, the nut 82, and the spacer 83 are made of a material having similar thermal conductivity to each other (for example, stainless steel). The washer 84 is made of a material having low thermal conductivity and heat resistance (for example, Teflon (registered trademark)) or a wave washer made of stainless steel having a reduced contact area to suppress thermal conductivity.

スペーサ83およびワッシャー84は、放熱部10と固定具60とが、直接接することを回避するために設けられる。すなわち、貫通孔15から突出したスペーサ83の端部83aが、固定具60と貫通孔15の端部15a、15bとの間に隙間を形成し、その隙間に耐熱性のワッシャー84が配置される。これにより、固定具60は、放熱部10に非接触となり、放熱部10の熱が固定具60に直接的に伝わることを回避できる。また、ボルト81、ナット82、およびスペーサ83は、略同様の熱伝導率を有する材料、または同一の材料とすることで、熱による伸縮量が同じとなり、熱膨張の影響により放熱部10の支持および遮熱板50への固定に及ぼす歪みなどの影響を抑制する。 The spacer 83 and the washer 84 are provided to prevent the heat radiating portion 10 and the fixture 60 from coming into direct contact with each other. That is, the end portion 83a of the spacer 83 protruding from the through hole 15 forms a gap between the fixture 60 and the ends 15a and 15b of the through hole 15, and the heat-resistant washer 84 is arranged in the gap. .. As a result, the fixture 60 is not in contact with the heat radiating portion 10, and the heat of the heat radiating portion 10 can be prevented from being directly transferred to the fixture 60. Further, by using materials having substantially the same thermal conductivity or the same material for the bolt 81, the nut 82, and the spacer 83, the amount of expansion and contraction due to heat becomes the same, and the heat dissipation unit 10 is supported by the influence of thermal expansion. In addition, the influence of distortion and the like on the fixing to the heat shield plate 50 is suppressed.

ここで、発熱部20の端子22に接続される配線26は、安全性の観点からビニールなどで被覆されている。このような配線の耐熱温度の観点から、高温となる放熱部10と同じ空間ではなく、遮熱板50で仕切られた収容空間55に収容される必要がある。また、端子22についても、埃などから保護する必要があるため、収容空間55に収容される必要がある。 Here, the wiring 26 connected to the terminal 22 of the heat generating portion 20 is covered with vinyl or the like from the viewpoint of safety. From the viewpoint of the heat-resistant temperature of the wiring, it is necessary to be accommodated in the accommodation space 55 partitioned by the heat shield plate 50, not in the same space as the heat radiating portion 10 which becomes high temperature. Further, since the terminal 22 also needs to be protected from dust and the like, it needs to be accommodated in the accommodation space 55.

例えば、直線的な形状の発熱部は、端子が両端に設けられるため、端子および配線の位置が複数箇所に分散してしまう。このような暖房機は、複数箇所に点在する端子および配線を保護するための部材を複数箇所に設ける必要がある。このため、部品点数の増加や、配線の高耐熱化、構成部品の配置に対する制約が課され、設計の自由度が阻害されてしまうと共に、対流を阻害して暖房効率の低下の要因となる。 For example, in the linear heat generating portion, since the terminals are provided at both ends, the positions of the terminals and the wiring are dispersed in a plurality of places. In such a heater, it is necessary to provide a member for protecting terminals and wiring scattered at a plurality of places at a plurality of places. For this reason, the number of parts is increased, the heat resistance of the wiring is increased, and restrictions are imposed on the arrangement of the component parts, which hinders the degree of freedom in design and hinders convection, which causes a decrease in heating efficiency.

これに対し、本実施形態における暖房機1は、U字形状の発熱部20を、端子22の方向を揃えて筐体30に収容する。端子22は前方に集約されるため、暖房機1は、前方のみに配線26および端子22を保護するための部材(前側遮熱板50a)を配置すればよい。この結果、暖房機1は、部品点数を削減でき、比較的低い耐熱性の配線26を用いることができ、筐体30内における制約を低減でき、設計の自由度を向上させることができる。 On the other hand, in the heater 1 of the present embodiment, the U-shaped heat generating portion 20 is housed in the housing 30 with the directions of the terminals 22 aligned. Since the terminals 22 are concentrated in the front, the heater 1 may arrange the wiring 26 and a member (front heat shield plate 50a) for protecting the terminals 22 only in the front. As a result, the heater 1 can reduce the number of parts, can use the wiring 26 having relatively low heat resistance, reduce the restrictions in the housing 30, and improve the degree of freedom in design.

また、暖房機1は、端子22を前方に集約できるため、全ての端子22と基板25との距離を小さくでき、配線26を短くできる。その結果、暖房機1を小型化できる。さらに、配線26類が1箇所に集約できるため、配線26類が複数箇所に分散している場合に比べて、空気がドラフトする流路面積を広く確保でき配線26類による対流の阻害がない、または少ないため、暖房効率を向上できる。 Further, since the heater 1 can consolidate the terminals 22 forward, the distance between all the terminals 22 and the substrate 25 can be reduced, and the wiring 26 can be shortened. As a result, the heater 1 can be miniaturized. Further, since the wirings 26 can be integrated in one place, a wider flow path area for drafting air can be secured as compared with the case where the wirings 26 are dispersed in a plurality of places, and the wirings 26 do not hinder convection. Or because there are few, the heating efficiency can be improved.

本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれると共に、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.

例えば、発熱部20が主に水平方向に延びるU字形状のシーズヒータである例を説明したが、上下方向に延びるU字形状であったり、シーズヒータ以外の他の種類のヒータであったりしてもよい。 For example, although the example in which the heat generating portion 20 is a U-shaped sheathed heater mainly extending in the horizontal direction has been described, it may be a U-shaped sheath extending in the vertical direction or a heater of a type other than the sheathed heater. You may.

例えば、図8は、変形例としての暖房機の図7に対応する説明図である。発熱部120は、主に上下方向に延び、長さ方向の略中心に曲げ部121を有するU字形状を有する。発熱部120は、端子122を下方に向って露出して各放熱部110の発熱部収容部111に収容されている。端子122は、配線126を介して基板125に接続されている。 For example, FIG. 8 is an explanatory diagram corresponding to FIG. 7 of a heater as a modified example. The heat generating portion 120 has a U-shape that extends mainly in the vertical direction and has a bent portion 121 at a substantially center in the length direction. The heat generating portion 120 exposes the terminal 122 downward and is housed in the heat generating portion accommodating portion 111 of each heat radiating portion 110. The terminal 122 is connected to the substrate 125 via the wiring 126.

このように、水平方向以外の方向である下方向に端子122が位置するように配置されている場合であっても、上述した暖房機1と同様の効果、特に配線26類の耐熱性が低くて済む効果を奏することができる。ただし、変形例としての暖房機は、下方にも配線126および端子122を保護するための部材150を設ける必要があること、空気入口40からの空気の取り入れを少ないものの阻害してしまうこと、空気入口40から意図せず吸い込まれた埃が端子122に付着する可能性があること、などの理由から、水平方向に向って端子が露出することが好ましい。 In this way, even when the terminals 122 are arranged so as to be located in the downward direction other than the horizontal direction, the same effect as that of the heater 1 described above, particularly the heat resistance of the wirings 26 is low. It can produce the effect that can be done. However, in the heater as a modification, it is necessary to provide a member 150 for protecting the wiring 126 and the terminal 122 below, the intake of air from the air inlet 40 is small but hindered, and the air It is preferable that the terminals are exposed in the horizontal direction for reasons such as the possibility that dust unintentionally sucked from the inlet 40 may adhere to the terminals 122.

また、発熱部20のU字形状の曲げ部21は、1箇所で曲線的に折れ曲がる態様に限らず、直角または曲線的に2箇所で折れ曲がる態様(いわゆるコ字状)であってもよい。さらに、放熱部10は、少なくとも一の発熱部20を内部に収容すればよく、複数の発熱部20を収容してもよい。 Further, the U-shaped bent portion 21 of the heat generating portion 20 is not limited to a mode in which the heat generating portion 20 is bent in a curved line at one position, and may be a mode in which the heat generating portion 20 is bent at two points in a right angle or a curve (so-called U-shape). Further, the heat radiating unit 10 may accommodate at least one heat generating unit 20 inside, and may accommodate a plurality of heat generating units 20.
