To manufacture the above-mentioned toilet seat 600, the heater 606 is bonded to the rear surface 604 of the toilet seat body 602 using an adhesive sheet 609 or the like, and then the toilet seat body 602 The bottom plate 608 is joined to the lower opening by ultrasonic welding or hot plate welding.
こうした暖房便座 6 0 0では、 樹脂糊や組付性の関係から確本体 6 0 2の 下部開口と底板 6 0 8との間に狭い隙間 Sを避けることができないので、 その隙 間に汚れ力 寸着する。 こうした狭い間隙に付着した汚れは、 雑巾等で拭いても容 易に除去することができない。 また、 エネルギーを均一に伝えるために超音波ホ ーン及び底板 6 0 8を平板に形成しているが、 こうした平面職では、 意匠性に 優れていないだけでなく、 便座本体 6 0 2の形状にも影響を与え、 座リ勝手がよ くかつ人間工学的に優れた曲面皿に形成することが難しいという問題もあった こうした問題を解消する技術として、 実開昭 6 1 - 1 3 6 8 5号公報に示すよ うに、 ヒータを便座内にインサート成形するもの力 ¾1られている。 すなわち、 図 5 7に示すように、 ¾ 便座は、 支持 2 0の上面 6 2 2に溝 6 2 4を形成 し、 この溝 6 2 4にヒータ 6 2 6を手作業によリ揷入支持し、 これを射出成顏 6 3 0にセットし、 キヤビティ 6 3 2に樹脂を充填して支持毅才 6 2 0に便座本 体 （図示省略） を積層形成することによリ、 ヒータ 6 2 6を支持謝 6 2 0と便 座本体との間に介在させたものである。 しかし、 この暖房便座では、 溝 6 2 4に ヒータ 6 2 6を挿入する作業が面倒であり、 また、 ヒータ 6 2 6が樹脂の射出圧 によリ溝 6 2 4から外れて上面 6 2 2に乗り上げることがあリ、便座本体の肉厚 が部分的に薄くなつて強度の低下を招くという問題もあった。 In such a heating toilet seat 600, a narrow gap S cannot be avoided between the lower opening of the main body 602 and the bottom plate 608 due to the resin glue and the assembling property. Just wear it. Dirt adhering to such narrow gaps cannot be easily removed by wiping with a rag or the like. In addition, the ultrasonic horn and the bottom plate 608 are formed in a flat plate in order to transmit energy uniformly, but in such a flat work, not only the design is not excellent, but also the shape of the toilet seat body 602 is formed. As a technique for solving such problems, it was difficult to form a curved dish with good ergonomics, and it was difficult to form such a dish. As shown in Japanese Patent Publication No. 5, the power of insert molding a heater into a toilet seat is known. That is, as shown in FIG. 57, the toilet seat has a groove 62 4 formed in the upper surface 62 2 of the support 20, and the heater 62 6 is manually inserted and supported in the groove 62 4. And this is the injection face The heater 626 is supported by filling the cavity 632 with resin and laminating the toilet seat body (not shown) on the support 6200. And the toilet seat body. However, in this heating toilet seat, it is troublesome to insert the heater 6 26 into the groove 6 24, and the heater 6 26 comes off the groove 6 2 4 due to the injection pressure of the resin, and the upper surface 6 2 2 There was also a problem that the thickness of the toilet seat body was partially reduced, resulting in a decrease in strength.
まだ、 他の従来の 便座として、 特開昭 6 1 - 2 4 7 4 2 6号公報に記載さ れているものがある。 この願便座の纖方法は、 貫通孔を有する面状発熱体を 射出成形型にセットして射出成形を行なって面状発熱体と とを一体成形した 予備成形体を成形し、 この予備成形体をさらに別の射出成形型にセットして、 面 状発熱体上に便座本体を積層形成している。 しカゝし、 便座のような大きな面積を 有するものに、 面状発熱体のような薄いシートを、 便座全体にわたって均一な発 熱特性をもたせて製造することは難しい。 このため、 面状発熱体を用いた場合に は、 暖房便座の便座表面を均一な に加熱することができないという問題があ つた。  As yet another conventional toilet seat, there is one disclosed in Japanese Patent Application Laid-Open No. Sho 61-244744. In the fiber method of the toilet seat, a preform is formed by integrally setting a planar heating element having a through-hole in an injection molding die and performing injection molding to form the preform. Is set in another injection mold, and the toilet seat body is laminated on the planar heating element. However, it is difficult to manufacture a sheet having a large area such as a toilet seat and a thin sheet such as a sheet heating element with uniform heat generation characteristics over the entire toilet seat. For this reason, when the planar heating element was used, there was a problem that the toilet seat surface of the heating toilet seat could not be heated uniformly.

また、 ヒータに限らず、 例えば、 サ一ミスタ、 ヒューズ等の電^ i能部品を便 座内にィンサ一ト成形する場合にも、 溶融樹脂の射出圧で電^ ϋ能部品がずれる ことから、 便座内に各種の電^能部品を所定位置にィンサ一トすることが難し いという問題があった。  In addition, not only heaters, but also electronic parts such as thermistors and fuses are molded into the toilet seat, because the injection pressure of the molten resin causes the electronic parts to shift. However, there has been a problem that it is difficult to insert various power components into predetermined positions in the toilet seat.

本発明に係る二層成,座では、 第 1層の面上に電^ 1能部品が取り付けられ 、 さらに電纖能部品をインサートするように第 2層が第 1層に積層される。 ま た、 第 2層を形成するための溶融樹脂の流れの上流側であり、 かつ電気機能部品 に近接した部位に遮蔽手段が設けられている。遮蔽手段は、 第 2層を成形するた めの溶融樹脂を射出する際に、 電気機能部品に加わる溶融樹脂の射出圧を低減し て、 電気機能部品の浮きやずれを防止する。  In the two-layer structure according to the present invention, the electric component is mounted on the surface of the first layer, and the second layer is laminated on the first layer so as to insert the electric fiber component. In addition, a shielding means is provided on the upstream side of the flow of the molten resin for forming the second layer and at a position close to the electric functional component. The shielding means reduces the injection pressure of the molten resin applied to the electric functional component when injecting the molten resin for molding the second layer, thereby preventing the electric functional component from floating or shifting.
上記遮蔽手段の好適な態様として、 第 1層の上面部に一体的に形成されたスロ —プを適用することができる。 スロープは、 電気機能部品に向かう溶融樹脂を滑 らかな面で電^!能部品の上部まで導くから、 電^能部品の側面に直接加わる 射出圧が小さくなる。 このスロープは、 第 1層に"^本的に形成されているから、 その構成及びその製造が簡単である。  As a preferable embodiment of the shielding means, a slope integrally formed on the upper surface of the first layer can be applied. Since the slope guides the molten resin toward the electrical functional component to the upper part of the electrical component with a smooth surface, the injection pressure directly applied to the side surface of the electrical component becomes smaller. Since this slope is formed in the first layer in a fundamental manner, its configuration and its manufacture are simple.
上記遮蔽手段の他の態様として、 第 1層の上面とほぼ面一に電気機能部品の上 面を設置する段部を形成し、 この段部に電^ 1能部品を設置することにより、 溶 融樹脂は、 第 1層の上面から電^ 1能部品の上部に滑らかに流れ、 電^!能部品 の側面に高い射出圧を加えない。  As another mode of the above-mentioned shielding means, a step for forming the upper surface of the electric functional component is formed substantially flush with the upper surface of the first layer, and the electric component is disposed on this step to obtain a molten metal. The molten resin flows smoothly from the upper surface of the first layer to the upper part of the electronic component, and does not apply a high injection pressure to the side surface of the electronic component.
遮蔽手段の別の態様として、 可撓性のシート材を用いることができ、 該シート 材によリ電纖能部品を覆うことによリ、 電纖能部品に加わる射出圧を鎌で きる。 このシート材は、 可撓性であるから電^ 1能部品の形状を問わずに、 該電 ^^能部品を覆うことができる。  As another mode of the shielding means, a flexible sheet material can be used, and by covering the electronic fiber component with the sheet material, the injection pressure applied to the electronic fiber component can be reduced. Since this sheet material is flexible, it can cover the electronic component regardless of the shape of the electronic component.
なお、 電^ 1能部品としては、 便座に電気的な機能をもたらす素子であれば、 各種のものを用いることができる。例えば、 便座に着座したことを検出する素子 として、 リミットスィッチ、 靜電容量型センサの m@、 圧電センサ等に適用でき る。 また、 ヒータで便座面を加熱する賴便座に用いた場合には、 ヒータのほか 、 便座面の を検出する Jtセンサや温度ヒューズ等に適用できる。 二層成形便座は、 電気機能部品をィンサートする第 1層及び第 2層であればよ いが、 好適な態様では、 第 1層として便器の上部に支持されると共に馬蹄形に形 成された支持 に適用し、 第 2層として支持 上にその一部が熱溶着さ;^ 座表面を有する便座本体に適用して構成することができる。 In addition, as the electric power component, various elements can be used as long as they provide an electric function to the toilet seat. For example, it can be applied to a limit switch, a capacitance sensor m @@, a piezoelectric sensor, etc., as an element for detecting the seating on a toilet seat. In addition, when the toilet seat surface is heated by a heater, the present invention can be applied to a Jt sensor for detecting the temperature of the toilet seat surface, a thermal fuse, and the like, in addition to the heater. The double-layered toilet seat may be a first layer and a second layer for inserting the electric functional component, but in a preferred embodiment, the first layer is supported on the upper part of the toilet as a first layer and is formed in a horseshoe shape. And a part thereof is thermally welded on the support as the second layer; ^ It can be configured to be applied to a toilet seat body having a seat surface.
第 1層と第 2層との間に電^ 1能部品をインサートした場合に、 電^ i能部品 の分だけ、 第 1層と第 2層との熱溶着する面積が減少して接合 ¾gが減少し易い が、 第 1層と第 2層とが互いに嚙み合って熱溶着する凹凸部を設けることにより 、 第 1層と第 2層との接合強度の低下を防止する。  When an electric component is inserted between the first layer and the second layer, the heat-bonded area between the first layer and the second layer is reduced by the amount of the electric component, and the joint is formed. Although the first layer and the second layer are provided with uneven portions that are bonded to each other and thermally welded, the joint strength between the first layer and the second layer is prevented from being reduced.
電纖能部品は、 外部から給電するための接続端子を必要とするが、 接続端子 は、 以下の構成により好適に取リ付けられる。 すなわち、 接続端子を、 第 1層に 形成した取付穴に嵌合支持する。 このとき、 接続端子の上部を取付穴から突出し た状態で取り付ける。 第 1層上に射出成形された第 2層は、 接 β子の上部をィ ンサートした状態で固定するから、 第 2層の成形と同時に接続端子を取り付ける ことができ、 その取 ^造及びその作業が容易になる。  Although the electric fiber component requires a connection terminal for supplying power from the outside, the connection terminal is suitably attached by the following configuration. That is, the connection terminals are fitted and supported in the mounting holes formed in the first layer. At this time, mount the connection terminal with the upper part protruding from the mounting hole. The second layer injection-molded on the first layer is fixed with the upper part of the contactor inserted, so that connection terminals can be attached at the same time as the formation of the second layer. Work becomes easier.
また、 接続端子を取付穴で嵌合支持する際に、 取付穴の内径を接続端子の瓶 よりかなり大きくして、 簡単に嵌合支持しょうとすると、 第 2層の溶融樹脂か 付穴に入り込み易いが、 シート材で接続端子の上部をシールすることによリ、 接 続端子と取付穴との間隙に加わる射出圧を して、取付穴と接続端子との間に 溶融樹脂が入リ込むのを防止する。  Also, when the connection terminal is fitted and supported in the mounting hole, the inside diameter of the mounting hole is considerably larger than the connection terminal bottle, and if it is attempted to easily support the fitting, the molten resin in the second layer may get into the hole. It is easy, but by sealing the upper part of the connection terminal with a sheet material, the injection pressure is applied to the gap between the connection terminal and the mounting hole, and the molten resin enters between the mounting hole and the connection terminal To prevent
また、 本発明は、 第 1層と第 2層とを樹脂にょリ積層すると共に、 第 1層と第 2層との間に電気機能部品をィンサートした二層成形便座の製造方法において、 第 1層を成形する工程と、  The present invention also provides a method for manufacturing a two-layer molded toilet seat in which a first layer and a second layer are laminated on a resin and an electric functional component is inserted between the first layer and the second layer. Forming a layer;
第 1層上に電^ t能部品をィンサートするように第 2層を射出成形で積層形成 する工程と、  A step of laminating the second layer by injection molding so as to insert the electric component on the first layer;
を具備し、  With
第 2層を積層形成する工程の前に、 第 1層に電^ ϋ能部品を取り付けると共に 、 電纖能部品に近接した第 1層上の部位であリかつ第 2層を形成するために射 出される溶融樹脂の流れの少なくとも上流側に、 電纖能部品に対する溶融樹脂 の射出圧を低減する遮蔽手段を設ける工程、 を施したことを,とする。 二層成藤座を製造する方法は、 第 1層を樹脂で成形した後に、 第 1層上に第 2層を射出成形により積層成形するが、 その前に、 電気機能部品及び遮蔽手段を 第 1層上に装着する工程が施される。 遮蔽手段は、 第 2層を形成するために射出 される溶融樹脂の流れの少なくとも上流側に、 溶融樹脂の射出圧を するよう に設けられるから、 該射出圧で電^ 1能部品力 置ずれすることを防止し、 また 、 電気機能部品のずれ等に伴う第 2層の部分的な薄肉部も生じない。 Before the step of laminating and forming the second layer, in order to attach the electronic component to the first layer and to form the second layer at a position on the first layer close to the electronic fiber component Providing, at least on the upstream side of the flow of the molten resin to be ejected, a shielding means for reducing the injection pressure of the molten resin on the electric fiber component. In the method of manufacturing the two-layer Naruto seat, after molding the first layer with a resin, the second layer is laminated and formed on the first layer by injection molding. A step of mounting on one layer is performed. The shielding means is provided at least at the upstream side of the flow of the molten resin injected to form the second layer so as to increase the injection pressure of the molten resin. In addition, a partial thin portion of the second layer does not occur due to displacement of the electric functional component.
ここで、 遮蔽手段は、 溶融樹脂を射出するためのゲートの付近で最も高いから 、 このゲートに近接した部位の上流側に設けることが好ましい。  Here, since the shielding means is highest near the gate for injecting the molten resin, it is preferable to provide the shielding means on the upstream side of a portion close to the gate.
なお、 電^ 1能部品及び遮蔽手段を第 1層に取リ付ける順序は、 特に限定され ず、 電纖能部品と遮蔽手段とを一体化したュニット体を形成する工程を用いる ほか、 第 1層上に電^ 1能部品を取リ付けてから遮蔽手段を取り付けてもよい。  The order in which the electrical component and the shielding means are attached to the first layer is not particularly limited, and a step of forming a unitary body integrating the electrical fiber component and the shielding means is used. The shielding means may be attached after the electronic components are attached on the layer.

【発明の実施するための最良の形態】 BEST MODE FOR CARRYING OUT THE INVENTION
図 1 発明の一 例に係る 便座を装着した洋式便器 2 0を示す 1見図 である。 図 1に示すように、 洋式便器 2 0は、 便器本体 2 2と、便器本体 2 2の 一端に枢支された暖房便座 4 0及び便蓋 2 6と、 洗浄用ノズルを装着した衛生洗 浄装置 3 0と、 洗浄水タンク 2 8と、 を備えている。  FIG. 1 is a first view showing a Western style toilet 20 equipped with a toilet seat according to an example of the invention. As shown in FIG. 1, the Western style toilet 20 is a sanitary flush equipped with a toilet body 22, a heating toilet seat 40 and a toilet lid 26 pivotally supported at one end of the toilet body 22, and a cleaning nozzle. A device 30 and a washing water tank 28 are provided.
上記暖房便座 4 0は、 図 2に示す馬 «の便座本体 5 0と、 この便座本体 5 0 内にインサート成形された図 3に示す支持翻 6 0とを備えている。 図 2は確 本体 5 0の平面図、 図 3は支持基材 6 0の平面図、 図 4は図 2の B— B線に沿つ た断面図である。 図 3に示す支持基材 6 0の上面 6 2には、 ■に沿った形状に ヒータ取付用溝 6 4カ 成されている。 また、 ヒータ取付用溝 6 4の間の上面 6 2及びその周辺部には、 被接着面 6 6が形成されている。  The heating toilet seat 40 includes a horse seat main body 50 shown in FIG. 2 and a supporter 60 shown in FIG. 3 which is insert-molded in the toilet seat main body 50. 2 is a plan view of the main body 50, FIG. 3 is a plan view of the support base 60, and FIG. 4 is a cross-sectional view taken along line BB of FIG. On the upper surface 62 of the support base material 60 shown in FIG. 3, heater mounting grooves 64 are formed in a shape along (1). In addition, an adhered surface 66 is formed on the upper surface 62 between the heater mounting grooves 64 and on the periphery thereof.
上記便座本体 5 0は、 2 0 0 の八8 S樹脂または融点 1 8 0°Cの P P樹 脂から形成され、 支持謝 6 0も同じ樹脂で形成されている。 よって、便座本体 5 0を形成するために溶融された樹脂が支持掛才 6 0に接触することによって、 その支持 ¾ 6 0の表面が溶融し、 射出された樹脂と溶融し合うことによって、 強固に固定される。 なお、 溶融した樹脂は、 支持 才 6 0に接触してその支持基 材 6 0の表面を溶融させるが、 接触することによってその溶融樹脂の は下が リ、 よって支持墓 6 0の内部まで溶けてしまうことはない。 また、 AB S樹脂 や P P樹脂を用いることによって、 ^MSもよく、 しかもコスト的にも安価に製作 できるものである。 The toilet seat body 50 is made of 200 88 S resin or PP resin having a melting point of 180 ° C., and the support 60 is also made of the same resin. Therefore, when the resin melted to form the toilet seat body 50 comes into contact with the support hook 60, the surface of the support 60 melts and melts together with the injected resin. Firmly fixed. The molten resin comes into contact with the support member 60 and melts the surface of the support substrate 60, but the contact lowers the molten resin, thereby melting the inside of the support grave 60. It won't. Also, by using ABS resin or PP resin, ^ MS is good and it can be manufactured at low cost.

The heater unit 70 includes a heater 72 inserted into the heater mounting groove 64, a heat transfer sheet 74 made of aluminum foil, and an adhesive sheet made of a double-sided tape or the like adhered to the heat transfer sheet 74. The heat transfer sheet 74 and the adhesive sheet 76 cover almost the entire upper surface 62, thereby holding the heater 72 in the heater mounting groove 64.
次に、 顧便座 4 0の 方法について説明する。  Next, the method of the toilet seat 40 will be described.
まず、 図 3に示す支持 ®f才 6 0を射出成形により，する。 また、 図 6に示す ように、 伝熱シート 7 4上に粘着シート 7 6の一方の第 1接着面 7 7を接着し、 さらに他方の第 2接着面 7 8にヒータ 7 2を接着する。 この作業は、 支持台 1 0 0を用いて行なわれる。 支持台 1 0 0には、 ばね力によリ上下動する位置決めピ ン 1 0 2が多数装着されている。 位置決めピン 1 0 2は、 支持^ ί 6 0のヒータ 取付用溝 6 4の？^に倣うように配置されている。 次に、 位置決めピン 1 0 2の 間にヒータ 7 2を配設し、 さらに、伝熱シート 7 4に接着された粘着シート 7 6 をシート押え部材 （図示省略） を使ってヒータ 7 2側に押し付ける。 これにより 、 位置決めピン 1 0 2が押し下げられて、 粘着シート 7 6にヒータ 7 2が接着す る。伝熱シート 7 4及び粘着シート 7 6を持ち上げることによリ、 粘着シート 7 6を介して伝熱シート 7 4にヒータ 7 2が接着して一体化する。 なお、 位置決め ピン 1 0 2の上端面には、 テフロン等のコーティングがされてぉリ、 粘着シート 7 6の第 2接着面 7 8に対して容易に剥離することができる。  First, the support 60 shown in FIG. 3 is formed by injection molding. Also, as shown in FIG. 6, one first adhesive surface 77 of the adhesive sheet 76 is adhered on the heat transfer sheet 74, and the heater 72 is adhered to the other second adhesive surface 78. This operation is performed using the support 100. A large number of positioning pins 102, which move up and down by spring force, are mounted on the support base 100. Positioning pin 102 is support ^ 60 heater mounting groove 64? It is arranged to follow ^. Next, a heater 72 is disposed between the positioning pins 102, and the adhesive sheet 76 adhered to the heat transfer sheet 74 is attached to the heater 72 using a sheet pressing member (not shown). Press. As a result, the positioning pins 102 are pushed down, and the heater 72 adheres to the adhesive sheet 76. By lifting the heat transfer sheet 74 and the pressure-sensitive adhesive sheet 76, the heater 72 is bonded to and integrated with the heat transfer sheet 74 via the pressure-sensitive adhesive sheet 76. The upper end surface of the positioning pin 102 is coated with Teflon or the like, so that it can be easily peeled off from the second adhesive surface 78 of the adhesive sheet 76.
次に、 図 7に示すように、 支持對才 6 0のヒータ取付用溝 6 4内にヒータ^ 1 ット 7 0のヒータ 7 2を挿入し、 粘着シ一ト 7 6の第 2接着面 7 8を支持勘才 6 0の被接着面 6 6に接着する。 その後、 図 8に示すように、 射出成形機の金型 1 1 0を構成する上型 1 1 2と下型 1 1 4の間に、 ヒータユニット 7 0等を装着し た支持 0をセットする。 このとき、 伝熱シート 7 4と上型 1 1 2の壁面と の間にキヤビティ 1 1 5カ¾ 成される。 続いて、 ゲート 1 1 6を通じて図 9に示 すように、 溶融樹脂 Rをキヤビティ 1 1 5内に充填する。 そして、 冷却固化した 後に離型して樹脂成形体を取り出す。 これによリ、 ^便座 4 0が^ ¾する。 上記 »例において、 支持基材 6 0のヒータ取付用溝 6 4内にヒータ 7 2を揷 入し、 この上から伝熱シート 7 4で覆っているから、伝熱シート 7 4は、 ヒータ 7 2を平滑な面にすると共に、 粘着シート 7 6を介して支持掛才 6 0の上面 6 2 に強固に接着する。 したがって、 射出成形時に、 溶融樹脂 Rは、 ヒータ 7 2力ず れたリ片寄ることがない。 その結果、 ヒータ 7 2の片寄りに伴う便座本体 5 0の 部分的な薄肉部がなく、 薄肉部による強度の低下を生じない。 Next, as shown in FIG. 7, the heater 72 of the heater unit 70 is inserted into the heater mounting groove 64 of the support member 60, and the second bonding surface of the adhesive sheet 76 is inserted. 7 8 is adhered to the surface 6 6 to be adhered of 60. Thereafter, as shown in FIG. 8, a heater unit 70 and the like are mounted between the upper die 11 and the lower die 11 constituting the mold 110 of the injection molding machine. Set support 0. At this time, a cavity 115 is formed between the heat transfer sheet 74 and the wall surface of the upper mold 112. Subsequently, as shown in FIG. 9, the molten resin R is filled into the cavity 115 through the gate 116. After being cooled and solidified, the mold is released and the resin molded body is taken out. By this, ^ toilet seat 40 ^ ^. In the above example, since the heater 72 is inserted into the heater mounting groove 64 of the support base material 60 and is covered with the heat transfer sheet 74 from above, the heat transfer sheet 74 is 2 is made to be a smooth surface, and firmly adhered to the upper surface 62 of the support hook 60 via the adhesive sheet 76. Therefore, at the time of injection molding, the molten resin R is not deviated by the heater 72. As a result, there is no partial thin portion of the toilet seat body 50 due to the bias of the heater 72, and the strength is not reduced by the thin portion.
また、 ヒータ 7 2を保持するための伝熱シート 7 4は、 アルミニウム箔により 形成されているから、 ヒータ 7 2の熱を効率よく 表面 5 2へ伝え熱損失も少 ない。  Further, since the heat transfer sheet 74 for holding the heater 72 is formed of aluminum foil, the heat of the heater 72 is efficiently transmitted to the surface 52 and the heat loss is small.
さらに、 伝熱シート 7 4へのヒータ 7 2の取付作業は、 支持台 1 0 0上の位置 決めピン 1 0 2の間にヒータ 7 2を位置決めして、 伝熱シート 7 4及び粘着シー ト 7 6をヒータ 7 2に押圧すれば、 ヒータ 7 2がヒータ取付用溝 6 4に沿った配 置で伝熱シート 7 4上に接着される。 よって、 ヒータ取付用溝 6 4をやや大きめ に形成すれば、 狭い溝にヒータ 7 2を押し入れる等の面倒な作業も不要であり、 ヒータ 7 2の取付作業も容易である。 なお、 逆にヒータ取付用溝 6 4を狭く形成 すれば、 接着強度の低い接着剤を用いることができ、 ヒータユニット 7 0の貼付 のやリ直しを容易に行なうことができる。  Further, when attaching the heater 72 to the heat transfer sheet 74, the heater 72 is positioned between the positioning pins 102 on the support base 100, and the heat transfer sheet 74 and the adhesive sheet are attached. When the heater 76 is pressed against the heater 72, the heater 72 is adhered onto the heat transfer sheet 74 at a position along the heater mounting groove 64. Therefore, if the heater mounting groove 64 is formed slightly larger, troublesome work such as pushing the heater 72 into the narrow groove is not required, and the heater 72 can be easily mounted. Conversely, if the heater mounting groove 64 is formed to be narrow, an adhesive having a low adhesive strength can be used, and the heater unit 70 can be easily attached and re-attached.
また、 便座本体 5 0は、 支持謝 6 0に一体化するのにインサート成形により 実現してぉリ、 その継ぎ目に隙間がないので清掃が容易である上に、 ¾ 便座 4 0自体の皿も支持 ¾ 6 0の皿に制約されることなく多様にすることができ 、 座リ 也や意匠性に優れた形状に容易に することができる。  In addition, the toilet seat body 50 is realized by insert molding in order to integrate it into the support member 60, and since there is no gap at the seam, it is easy to clean. Support ¾ It can be diversified without being limited by the dish of 60, and it can be easily formed into a shape with excellent seating and design.
次に、 本発明に係る他の 例について説明する。 図 1 0は他の 例に係る 暖房便座 4 0 Aの要部を拡大して示す断面図である。 図 1 0に示すように、 暖房 便座 4 O Aの支持謝 6 O Aには、 ヒータ取付用溝 6 4 Aが形成されている。 ヒ —タ取付用溝 6 4 Aには、 ヒータュニット 7 0のヒータ 7 2が 2本揷入されると 共に両ヒータ 7 2間がヒータ側凹所 7 0 aになっている。 このヒータ側凹所 7 0 aには、 便座本体 5 O Aの突条部 5 0 aが入り込んでいる。 Next, another example according to the present invention will be described. FIG. 10 is an enlarged cross-sectional view showing a main part of a heating toilet seat 40A according to another example. As shown in FIG. 10, a heater mounting groove 64A is formed in the supporting member 6OA of the heating toilet seat 4OA. When two heaters 72 of heater unit 70 are inserted into heater mounting groove 64 A, In both cases, the space between both heaters 72 is a heater side recess 70a. The ridge 50a of the toilet seat body 5OA enters into the heater side recess 70a.
上記 ¾ 便座 4 O Aを！^するには、 まず、 ヒータユニット 7 O Aを製造する 。 図 1 1に示すように、 支持台 1 0 O Aには、 位置決めピン 1 0 2が 2列設けら れている。 これらの位置決めピン 1 0 2の列間隔は、 2本のヒータ 7 2をヒータ 取付用溝 6 4 A内に取り付ける間隔にほぼ等しくなつている。 次に、 伝熱シート Above ¾ Toilet seat 4 O A! To do so, first, manufacture the heater unit 7OA. As shown in FIG. 11, the support base 10OA is provided with two rows of positioning pins 102. The row interval of these positioning pins 102 is substantially equal to the interval at which the two heaters 72 are mounted in the heater mounting groove 64A. Next, heat transfer sheet
7 4をヒータ 7 2の位置決めピン 1 0 2上に置き、 さらにシート押え部材 1 0 4 でヒータ 7 2側へ押さえつける。 シート押え部材 1 0 4には、 型付け溝 1 0 4 a が形成されている。 これにより、 図 1 2に示す伝熱シート 7 4に粘着シート 7 6 を介してヒータ 7 2カ 着されると共に、 型付け溝 1 0 4 aに倣ったヒータ側凹 所 7 0 aを有するヒータュニット 7 O Aが作成される。 Place 74 on the positioning pins 102 of the heater 72, and press down on the heater 72 side with the sheet holding member 104. A molding groove 104 a is formed in the sheet holding member 104. As a result, the heater unit 72 is attached to the heat transfer sheet 74 shown in FIG. 12 via the adhesive sheet 76, and the heater unit 7 has a heater side recess 70a following the mold groove 104a. An OA is created.
次に、 ヒータユニット 7 O Aのヒータ 7 2を支持 ォ 6 O Aのヒータ取付用溝 Next, the heater 72 of the heater unit 7 O A is supported.
6 4 Aに挿入すると共に、 粘着シート 7 6を介してヒータ取付用溝 6 4 Aの壁面 に接着する。 ヒータ側凹所 7 0 aの底部分は、 ヒータ取付用溝 6 4 Aの底面に接 着される。 このとき、 ヒータ取付用溝 6 4 Aは、 ヒータ 7 2の 2本分よりかなり 大きい断面積を有しているので、 ヒータ 7 2の挿入作業を簡単に行なえる。 続いて、 図 1 3に示すように、 ヒータユニット 7 O Aを装着した支持 ¾ 6 0 Aを金型 1 1 0にセットして射出成形を行なう。 このとき、 溶融樹脂 Rは、 キヤ ビティ 1 1 5 A内に充填されるが、 まず、 伝熱シート 7 4の平らなキヤビティ 1 1 5 a部分を先行して流れ、 その後、 ヒータ側凹所 7 0 aによリ形成される凹所 1 1 5 bに徐々に流れ込む。 したがって、 凹所 1 1 5 bに溶融樹脂 Rが流れ込む ときには、 射出圧が小さいので、 ヒータ 7 2がヒータ取付用溝 6 4 Aからずれる ことなく、 よって、 便座本体 5 O Aに薄肉部が生じない。 Attach it to the heater mounting groove 64 A through the adhesive sheet 76 while inserting it into the heater mounting groove 64 A. The bottom portion of the heater side recess 70a is attached to the bottom surface of the heater mounting groove 64A. At this time, since the heater mounting groove 64 A has a cross-sectional area considerably larger than the two heaters 72, the heater 72 can be easily inserted. Subsequently, as shown in FIG. 13, the support A A to which the heater unit 7 OA is mounted is set in a mold 110 and injection molding is performed. At this time, the molten resin R is filled into the cavity 115A. First, the molten resin R flows ahead of the flat cavity 115a of the heat transfer sheet 74, and then the heater side recess 7 The recesses formed by 0a gradually flow into the recesses 1 1 5b. Therefore, when the molten resin R flows into the recesses 1 15 b, the injection pressure is small, so that the heater 72 does not deviate from the heater mounting groove 64 A, so that a thin portion does not occur in the toilet seat body 5 OA. .
図 1ないし図 1 3に説明した纖例では、 ヒータユニット 7 0 , 7 O Aの構成 として、 伝熱シート 7 4の一方の面に粘着シート 7 6を貼付し、 その粘着シート In the fiber examples described in FIGS. 1 to 13, an adhesive sheet 76 is attached to one surface of the heat transfer sheet 74 as a configuration of the heater units 70 and 7OA, and the adhesive sheet is provided.
7 6にヒータ 7 2を接着しているが、 これに限らず、 図 1 4に示すように、 伝熱 シート 7 4 Bと粘着シート 7 6 Bとの間にヒータ 7 2を介在させてもよい。 この 場合には、 図 1 5に示すように、 粘着シート 7 6 Bの第 2接着面 7 8 Bがヒータ 取付用溝 6 4の内側にも接着するので、 接着強度が増すと共に、 ヒータ 7 2力 熱シート 7 4 Bに直接接触するので、 伝熱効率が高くなるという効果もある。 な お、 図 1 6に示すように、 ヒータ取付用溝 6 4 B間の被接着面 6 6 Bを上面 6 2 より、 やや低くして、 ヒータ 7 2をヒータ取付用溝 6 4 Bへ位置決めして挿入す る作業を容易にしてもよい。 The heater 72 is adhered to 76, but is not limited to this. As shown in FIG. 14, the heater 72 may be interposed between the heat transfer sheet 74B and the adhesive sheet 76B. Good. In this case, as shown in FIG. 15, the second adhesive surface 78B of the adhesive sheet 76B also adheres to the inside of the heater mounting groove 64, so that the adhesive strength increases and the heater 72 Power Direct contact with the heat sheet 74B also has the effect of increasing heat transfer efficiency. As shown in Fig. 16, the surface to be bonded 66 B between the heater mounting grooves 6 4 B is slightly lower than the upper surface 6 2, and the heater 72 is positioned in the heater mounting grooves 6 4 B. The insertion work may be facilitated.
また、 図 1 7及び図 1 8に示すように、 伝熱シート 7 4 Cと粘着シート 7 6 C との間にポリエステル等からなる断熱シート 7 9を介在させてもよい。 これによ リ、 支持基材 6 0側への熱が遮断されて、 ヒータ 7 2の便座表面側への熱効率が 一層向上するという効果がある。 この場合において、 断熱シート 7 9の一部を切 リ欠いて、 粘着シート 7 6 Cを伝熱シート 7 4に直接接着して、 3層の積層 を強固にすることも可能である。  As shown in FIGS. 17 and 18, a heat insulating sheet 79 made of polyester or the like may be interposed between the heat transfer sheet 74C and the adhesive sheet 76C. Thereby, the heat to the support base material 60 side is shut off, and the heat efficiency of the heater 72 to the toilet seat surface side is further improved. In this case, it is also possible to cut out a part of the heat insulating sheet 79 and directly adhere the adhesive sheet 76 C to the heat transfer sheet 74 to strengthen the three-layer laminate.
図 1 9は便座本体 5 0 Eにィンサ一トされる支持對才 6 0 Eを中空構造にした ものである。 この実施例では、 便座 4 0 E自体を、 同じ材料量でも軽量かつ 容積を大きく形成できるので、 質量感に伴う高級感をもたらすことができる。 ま た、 支持斟才 6 0 Eの底面部 6 9に、 クッション部 1 5 0を設ければ、 クッショ ン部 1 5 0を上面部 6 2 Eの下部に直接形成するより低くすることができる。 こ れにより、 クッション部 1 5 0の 付近の清掃を簡単にできる。  FIG. 19 shows a support member 60E inserted into the toilet seat body 50E having a hollow structure. In this embodiment, the toilet seat 40E itself can be formed with a light weight and a large volume even with the same material amount, so that it is possible to provide a sense of quality associated with a sense of mass. In addition, if a cushion portion 150 is provided on the bottom portion 69 of the support portion 60E, the cushion portion 150 can be made lower than that formed directly below the upper portion 62E. . This makes it easy to clean the vicinity of the cushion 150.
なお、 図 2 0に示すように、 便座本体 5 0 Fは、 支持謝 6 O Fの底面部 6 9 を含めた全周にわたって形成してもよい。 この場合には、 よリー層意匠性を高め ることができる。  As shown in FIG. 20, the toilet seat body 50F may be formed over the entire circumference including the bottom portion 69 of the support member 6OF. In this case, the design property of the Lee layer can be further improved.
図 2 1は他の^ 便座 4 0 Gの端部を示す断面図である。 支持 0 Gと便 座本体 5 0 Gとの間に伝熱シート 7 4 Gが介在すると、 接合強度が低下しやすい が、 これを防止するために、 以下の各種の構成が採られている。  FIG. 21 is a sectional view showing an end of another toilet seat 40G. If the heat transfer sheet 74 G is interposed between the support 0 G and the toilet seat main body 50 G, the joining strength is apt to decrease. However, in order to prevent this, the following various configurations are adopted.
① 伝熱シート 7 4 Gの一部を切り欠いた窓部 7 5を形成し、 この窓部 7 5を介 して便座本体 5 0 Gと支持 才 6 0 Gとが一体的に溶着した構成である。  (1) A configuration in which a window 75 with a part of the heat transfer sheet 74 G cut out is formed, and the toilet seat body 50 G and the supporter 60 G are integrally welded through the window 75. It is.
② 伝熱シート 7 4 Gに窓部 7 5を形成すると共に、 この窓部 7 5の位置に合わ せて支持謝才 6 0 Gの上面 6 2に凹所 6 3を形成する。 そして、便座本体 5 0 G の射出成形時に、 溶融樹脂が窓部 7 5を介して凹所 6 3内に入り込んで突部 5 3 を形成する。 これにより、 便座本体 5 0 Gと支持 ¾才 6 0 Gの接合面積が増大す る。 ③ 支持豁才6 O Gの端部に凹所 6 7を形成する。 そして、 便座本体 5 0 Gの射 出成形時に、 溶融樹脂が凹所 6 7に入り込んで便座本体 5 0 Gの一部が支持謝 6 0 Gの端部を把持する把持部 5 8を形成する。 (2) A window 75 is formed in the heat transfer sheet 74G, and a recess 63 is formed in the upper surface 62 of the supporter 60G in accordance with the position of the window 75. Then, at the time of injection molding of the toilet seat body 50G, the molten resin enters the recess 63 through the window 75 to form the projection 53. As a result, the joint area between the toilet seat body 50 G and the supporter 60 G is increased. ③ Form a recess 6 7 at the end of the supporting OG 6 OG. When the toilet seat body 50G is injection-molded, the molten resin enters the recess 67, and a part of the toilet seat body 50G forms a grip portion 58 for gripping the end of the support member 60G. .

Adhere firmly.
図 2 2及び図 2 3は支持凝才と便座本体との継ぎ目にバリを生じない暖房 ^j^ を ¾する方法を示す図である。 射出成形機の金型 1 1 0 Hは、 上型 1 1 2 H、 下型 1 1 4 H及びスライド型 1 1 8を備え、 スライド型 1 1 8は、 支持基材 6 0 Hと便座本体との継ぎ目 6 0 hに設置され、 図示上下方向ヘスライド可能に構成 されている。 射出成形時に、 キヤビティ 1 1 5 Hに溶融樹脂 Rが充填され、 その 溶融樹脂 Rがスライド型 1 1 8に達すると、 このスライド型 1 1 8によリ射出初 期の樹脂圧を受ける。 その後、 スライド型 1 1 8を下方にスライドさせる。 スラ イド型 1 1 8力 かれたキヤビティ 1 1 5 Hに溶融樹脂 Rが徐々に充填される。 すなわち、 支持謝 6 0 Hの継ぎ目 6 0 hの部分に加えられる溶融樹脂 Rは、 そ の射出初期の高い樹脂圧のときにはスライド型 1 1 8で受け、 樹脂圧が低くなつ たときに、 スライド型 1 1 8が除かれて継ぎ目 6 O hで直接受け、 そのキヤビテ ィ 1 1 5 Hに充填される。 したがって、 支持掛才 6 0 Hと便座本体との継ぎ目 6 0 hとなる部分で高 ^ ί出圧で溶融樹脂 Rが充填されず、 支持 ¾|才 6 0 Ηと 本体との継ぎ目 6 0 hにバリが生じない。  FIG. 22 and FIG. 23 are diagrams showing a method of performing heating ^ j ^ without generating burrs at the joint between the supporter and the toilet seat body. The mold 110 H of the injection molding machine includes an upper mold 112 H, a lower mold 114 H, and a slide mold 118, and the slide mold 118 includes a support base 60 H and a toilet seat body. It is installed at the joint 60h, and is slidable up and down in the figure. At the time of injection molding, the cavity 115H is filled with the molten resin R, and when the molten resin R reaches the slide die 118, the slide die 118 receives the resin pressure at the beginning of the injection. Thereafter, the slide mold 1 18 is slid downward. The molten resin R is gradually filled in the cavity 1 15 H that has been subjected to the slide type 1 18 force. In other words, the molten resin R applied to the joint 60 h of the support member 60 H is received by the slide mold 118 at the time of high resin pressure at the beginning of the injection, and the molten resin R slides when the resin pressure becomes low. The mold 118 is removed and received directly at seam 6Oh and its cavity 115H is filled. Therefore, at the part where the joint between the support member 60 H and the toilet seat main body is 60 h, the molten resin R is not filled at a high ^ ί output pressure, and the joint between the support member | No burrs are formed.

次に、 暖房便座 40 Lの纖方法について説明する。  Next, the fiber method of the heating toilet seat 40L will be described.
まず、 図 25に示す支持謝 60Lを射出成形により ilする。 一方、 別のェ 程にて、 図 31に示すように、 伝熱シート 74 L上に粘着シート 76 Lの一方の 第 1接着面 77 Lを接着し、 さらに他方の第 2接着面 78 Lにヒータ 72 Lを接 着する。 この作業は、 支持台 100 Lを用いて行なわれる。 支持台 100 Lには 、 ばね力にょリ上下動する位置決めピン 102 Lが多数装着されている。 位置決 めピン 102Lは、 支持基材 60L上でヒータ 72 Lが配される位置に沿うよう に設けられている。 次に、 位置決めピン 102Lの間にヒータ 72 Lを配設し、 さらに、 伝熱シート 74Lに接着された粘着シート 76 Lをシート押え部材 （図 示省略） を使ってヒータ 72 L側に押し付ける。 これにより、 位置決めピン 10 2 Lが押し下げられて、 粘着シート 76 Lにヒータ 72 Lが接着する。続いて、 伝熱シート 74 L及び粘着シート 76 Lを持ち上げることにより、 粘着シート 7 6 Lを介して伝熱シート 74Lとヒータ 72 Lとカ继着一体化したヒータュニッ ト 70 Lが製造される。 なお、 位置決めピン 102 Lの上端面には、 テフロン等 のコーティングがされており、 粘着シート 7 6 Lの第 2接着面 7 8 Lに対して容 易に剥離することができる。 First, the support 60L shown in FIG. 25 is illuminated by injection molding. On the other hand, in another step, as shown in FIG. 31, one of the first adhesive surfaces 77L of the adhesive sheet 76L is adhered onto the heat transfer sheet 74L, and further to the other second adhesive surface 78L, as shown in FIG. Connect heater 72 L. This operation is performed using a 100 L support. A large number of positioning pins 102L that move up and down by a spring force are mounted on the support 100L. The positioning pin 102L is provided along the position where the heater 72L is disposed on the support base material 60L. Next, the heater 72L is disposed between the positioning pins 102L, and the adhesive sheet 76L adhered to the heat transfer sheet 74L is pressed against the heater 72L using a sheet pressing member (not shown). As a result, the positioning pin 102 L is pushed down, and the heater 72 L adheres to the adhesive sheet 76 L. Subsequently, the heat transfer sheet 74L and the adhesive sheet 76L are lifted to produce a heater unit 70L integrally bonded to the heat transfer sheet 74L and the heater 72L via the adhesive sheet 76L. In addition, Teflon etc. The adhesive sheet 76 L can be easily peeled off from the second adhesive surface 78 L of the adhesive sheet 76 L.
次に、 図 3 2に示すように、 支持基材 6 0 L上にヒータユニット 7 0 Lのヒー タ 7 2 Lを載置し、 粘着シート 7 6 Lの第 2接着面 7 8 Lを支持謝 6 0 Lのヒ —タ取付用平面 6 2 L aに接着する。 このとき、 伝熱シート 7 4 Lは、 図 2 8に 示すようにヒータ 7 2 Lの部分で盛り上がるが、 比較的岡 IJ性の高いシート材であ るから、 裾野の広い滑らかな傾斜面 7 4 L aになってヒータ取付用平面 6 2 L a に接着される。 なお、 伝熱シート 7 4 Lは、 ヒータ 7 2 Lのヒータ端線 7 2 L a にて支持 S 6 0 Lの遮蔽^ 6 2 L bと共に覆う （図 3 0参照） 。  Next, as shown in FIG. 32, the heater 72 L of the heater unit 70 L is placed on the support base material 60 L, and the second adhesive surface 78 L of the adhesive sheet 76 L is supported. Thanks 60 L of heater mounting surface 62 Glue to 2 La. At this time, the heat transfer sheet 74L rises up at the heater 72L as shown in Fig. 28, but since it is a sheet material with relatively high OJ IJ properties, it has a wide slope and a smooth slope. It becomes 4 La and is adhered to the heater mounting plane 62 La. The heat transfer sheet 74 L is covered by the heater end line 72 L a of the heater 72 L together with the shielding S 62 L of the heater S 62 L (see FIG. 30).
その後、 図 3 3に示すように、 射出成形機の金型 1 1 0 Lを構成する上型 1 1 2 と下型1 1 4 Lの間に、 ヒータユニット 7 0 L等を装着した支持掛才 6 0 L をセットする。 この状態では、 金型 1 1 0 Lのゲート 1 1 6 Lの位置は、 支持基 材 6 0 Lの遮蔽^ 6 2 L bに対向する位置に設けられている。 この支持 ¾+才6 0 Lのセットにより、 伝熱シート 7 4 Lと上型 1 1 2 Lの壁面との間にキヤビテ ィ 1 1 5 Lが形成される。 続いて、 ゲート 1 1 6 Lを通じて溶融樹脂 R (図 3 4 ) をキヤビティ 1 1 5 L内に充填する。 溶融樹脂 Rは、 図 3 5に示すように、 ゲ ート 1 1 6 Lから矢印の方向に沿って流れ、 キヤビティ 1 1 5 L内を充填する。 そして、 冷却固化した後に離型して樹脂成形体を取り出す。 そして、 図示しない ヒューズの接騰の作業を行なうことによリ麵«4 0 Lが する。  Then, as shown in Fig. 33, a support hook with heater unit 70L etc. installed between the upper mold 112 and the lower mold 114L constituting the mold 110L of the injection molding machine. Set the age 60 L. In this state, the position of the gate 1116L of the mold 110L is provided at a position facing the shielding layer 62B of the support base 60L. With this set of support + 60 L, a cavity 115 L is formed between the heat transfer sheet 74 L and the wall surface of the upper mold 112 L. Subsequently, molten resin R (FIG. 34) is charged into the cavity 115 L through the gate 116 L. As shown in FIG. 35, the molten resin R flows from the gate 116 L in the direction of the arrow and fills the cavity 115 L. Then, after cooling and solidifying, the mold is released and the resin molded body is taken out. Then, by performing the work of raising the fuse (not shown), 40 L is released.
上記魏例によれば、 上記伝熱シート 7 4 Lは、 支持謝 6 0 L上のヒータ 7 2 Lを裾野の広い山状に覆っているから、 ゲート 1 1 6 Lから射出される溶融樹 脂 Rは、 図 3 4に示すように、 伝熱シート 7 4 L上をスムーズに流れる。 したが つて、 その高 ^ f出圧がヒータ 7 2 Lに直接加わらないから、 ヒータ 7 2 Lがズ レたリ、 片寄ったリすることもなく、 その結果、 ヒータ 7 2 Lのズレに伴う^^ 本体 5 0 Lの部分的な薄肉部も生じない。 しかも、 ヒータ 7 2 Lを伝熱シート 7 Lで裾野の広い状態に覆うのに、 伝熱シ一ト 7 4 L自体をやや剛性の高いシ一 ト材で形成すればよいから、 その構成及び i¾t作業も簡単である。  According to the above Wei example, since the heat transfer sheet 74 L covers the heater 72 L on the support plate 60 L in a mountain shape with a wide skirt, the molten wood injected from the gate 116 L The fat R smoothly flows on the heat transfer sheet 74L as shown in FIG. Therefore, since the high ^ f output pressure is not directly applied to the heater 72 L, the heater 72 L is not displaced or offset, and as a result, the heater 72 L is displaced. ^^ There is no partial thin part of 50L of the main body. Moreover, in order to cover the heater 72 L in a wide skirt with the heat transfer sheet 7 L, the heat transfer sheet 74 L itself may be formed of a somewhat rigid sheet material. i¾t work is also easy.
また、 ヒータ 7 2 Lを保持するための伝熱シート 7 4 Lは、 アルミニウム箔に ょリ形成されているから、 ヒータ 7 2 Lの熱を効率よく便座表面 5 2 Lへ伝え熱 損失も少ない。 Also, since the heat transfer sheet 74 L for holding the heater 72 L is formed of aluminum foil, the heat of the heater 72 L is efficiently transferred to the toilet seat surface 52 L. There is little loss.
さらに、 上記 ¾5S例において、 ゲート 1 1 6 L付近の支持謝 6 0 Lに加わる 射出圧は高いけれども、 ゲート 1 1 6 Lに近接した位置に、 遮蔽突条 6 2 L bが 設けられており、 この遮蔽幾 6 2 L bは、 溶融樹脂 Rの高い射出圧がヒータ 7 2 Lのヒータ端線 7 2 L aに加わるのを防ぐから、 ヒータ端線 7 2 L aのズレも なくすことができる。  Furthermore, in the above 5S example, although the injection pressure applied to 60 L near the gate 116 L is high, a shielding ridge 62 Lb is provided at a position close to the gate 116 L. However, since this shielding plate 62 Lb prevents the high injection pressure of the molten resin R from being applied to the heater end line 72 La of the heater 72 L, it is possible to eliminate the displacement of the heater end line 72 La. it can.
上記実施例では、 金型 1 1 0 Lのゲート 1 1 6 Lを支持基材 6 0 Lの外周側に 設け、 該ゲート 1 1 6 Lに対向した支持謝 6 O Lの部位に、 遮蔽錢 6 2 L b を設けたが、 図 3 6に示すように、 ゲート 1 1 6 Mを内側部に設けた場合には、 溶融樹脂 Rは、 矢印方向へ流れるから、 図 3 7に示すように、 遮蔽絲 6 2 Mb は、 ゲート 1 1 6 Mに対向した内側に設けることが必要である。  In the above embodiment, the gate 110 L of the mold 110 L is provided on the outer peripheral side of the support base material 60 L, and the shielding member 6 OL is provided at the portion of the support member 6 OL facing the gate 116 L. Although 2 Lb is provided, as shown in FIG. 36, when the gate 116 M is provided inside, as shown in FIG. 36, the molten resin R flows in the direction of the arrow, and as shown in FIG. 37, The shielding thread 62 Mb needs to be provided inside facing the gate 116 M.
図 3 8は他の実施例に係る暖房便座を製造するための射出成形工程を示す。 ゲ ート 1 1 6 N付近の支持基材 6 O Nの表面には、 ヒータ取付用溝 6 3 N b *^ されており、 該ヒータ取付用溝 6 3 N bにヒータ 7 2 Lのヒータ端線 7 2 L aが 保持されている。 これにより、 ヒータ端線 7 2 L aは、 ヒータ取付用溝 6 3 Nb によリ堅固に保持されているから、 ゲート 1 1 6 Nからの溶融樹脂 Rの高 谢出 圧でズレることがない。 なお、 ヒータ取付用溝 6 3 N bへヒータ端線 7 2 L aを 挿入する作業は、 ゲート 1 1 6 N付近だけでよく、 支持基材 6 O Nの全面にわた つていないから、 その作業もさほど面倒にならない。 なお、 ヒータ取付用溝 6 3 N bは、 ゲート 1 1 6 N付近に 1本だけ形成するほか、 射出圧及び樹脂の流れに 応じて、 図 3 9に示すように、 複数のヒータ取付用溝 6 3 P bを形成し、 該ヒー タ取付用溝 6 3 P bにヒータ端線 7 2 L aを保持させてもよい。  FIG. 38 shows an injection molding process for manufacturing a heating toilet seat according to another embodiment. On the surface of the support base 6 ON near the gate 1 16 N, a heater mounting groove 6 3 Nb * ^ is formed. The heater mounting groove 6 3 Nb has a heater end of a heater 7 2 L. Line 72 La is held. As a result, the heater end line 72 La is firmly held by the heater mounting groove 63 Nb, so that it does not shift due to the high discharge pressure of the molten resin R from the gate 116 N. . The work of inserting the heater end line 72 La into the heater mounting groove 63 Nb only needs to be performed near the gate 116 N, and does not extend over the entire surface of the support base 6 ON. Not too much trouble. In addition, only one heater mounting groove 63Nb is formed in the vicinity of the gate 116N, and a plurality of heater mounting grooves are provided according to the injection pressure and the flow of resin, as shown in FIG. 6 3 Pb may be formed, and the heater end line 72 La may be held in the heater mounting groove 63 Pb.
なお、 伝熱シートがヒータを裾野の広い状態で覆う手段としては、 伝熱シート 自体を剛性の大きいアルミニウム箔て 成するほか、 粘着シートに剛性をもたせ たリ、 ヒータと支持勘才の接する部分に樹脂製の漆喰等を詰めて、 その上から伝 熱シートで覆う等の各種の手段であつてもよい。  The heat transfer sheet covers the heater with a wide skirt, in addition to the heat transfer sheet itself made of aluminum foil with high rigidity, the adhesive sheet with rigidity, and the contact between the heater and the support. Various means may be used, such as filling resin stucco or the like with a heat transfer sheet.
