Description
【０００１】[0001]
本考案は、洋式便器に用いられる暖房便座に関するものである。 The present invention relates to a heated toilet seat used in a Western style toilet bowl.
【０００２】[0002]
従来、この種の暖房便座について各種の提案がなされている。例えば、特開昭 ６１−２４７４２６号公報では、２０〜３０ワット程度の導電性プラスチック製 の面状発熱体を、先ず裏面本体にインサ−ト成形し、この面状発熱体に設けた貫 通孔から裏面本体と連なった突起を突出させ、次に、表面本体のインサ−ト成形 を行う。このようにして、面状発熱体を内蔵して２層成形すれば、面状発熱体と 便座本体とのインサ−ト境界部分のずれやクラックが発生しにくい、という提案 が紹介されている。 Heretofore, various proposals have been made for this type of heated toilet seat. For example, in Japanese Unexamined Patent Publication No. 61-247426, a sheet heating element made of a conductive plastic of about 20 to 30 watts is first insert-molded on the back body, and a through hole provided in the sheet heating element. Then, the protrusion connected to the back side main body is projected, and then the front side main body is insert-molded. In this way, a proposal has been introduced that if the sheet heating element is built-in and two-layer molding is performed, it is unlikely that the insert boundary portion between the sheet heating element and the toilet seat body is displaced or cracked.
【０００３】 また、特開平３−７１８１５号公報では、ステンレス製の金属箔の両面を樹脂 フィルムでラミネ−トし、更に、その両外面にホットメルト接着剤を設けた面状 発熱体を用い、この面状発熱体に貫通孔を設け、この貫通孔を外型用コアに突出 されたゲ−トに挿入して、面状発熱体をこの外型用コア上でずれることなく配置 させる。そして、この外型用コアと外型用キヤビティとの間に樹脂をゲ−トより 充填して表面本体を成形する。次いで、外型用コアを開くと、面状発熱体がイン サ−トされた表面本体は、外型用キヤビティ側に残っており、しかも、ゲ−トの 貫通孔も残っているので、この外型用キヤビティを内型用コアに合せて裏面本体 を成形する。このようにして面状発熱体を内蔵して２層成形すれば、貫通孔を介 して表面本体と裏面本体とが強力に接着されると共に、面状発熱体の配置精度を 損なわない、という提案が紹介されている。Further, in Japanese Patent Laid-Open No. 3-71815, a sheet metal heating element in which both sides of a stainless metal foil are laminated with resin films and hot melt adhesives are provided on both outer surfaces thereof is used. A through hole is provided in this planar heating element, and the through hole is inserted into the gate protruding from the outer die core so that the planar heating element is arranged on the outer die core without displacement. Then, a resin is filled from the gate between the outer mold core and the outer mold cavity to mold the surface main body. Next, when the outer die core is opened, the surface body with the sheet heating element inserted remains on the outer die cavity side, and the gate through hole also remains. Align the outer mold cavity with the inner mold core and mold the back body. In this way, if the planar heating element is built in and two-layer molding is performed, the front surface main body and the back surface main body are strongly adhered to each other through the through hole, and the placement accuracy of the planar heating element is not impaired. Suggestions are introduced.
【０００４】 これらの例から明らかなように、従来の暖房便座には面状発熱体がインサ−ト 成形されており、一方、一般の面状発熱体は種々の製法で作られているが、その 一つに、金属箔に絶縁性プラスチックを貼着した後、この金属箔の上面に発熱素 子パタ−ンを形成するためのレジストをスクリ−ン印刷または写真印刷し、これ を腐蝕液によってエッチングして浮上がらせ、更に、この発熱素子パタ−ンの上 面に印刷されたレジスト膜を除去した後、この発熱素子パタ−ンの上面から樹脂 フィルムを貼着した面状発熱体が知られている。 ところが、かかる金属箔を発熱素子パタ−ンにした面状発熱体を用いてインサ −ト成形すると、その生産工程で電気的不良品が発生する、という問題があった 。As is clear from these examples, the conventional heating toilet seat is insert-molded with a planar heating element, while a general planar heating element is manufactured by various manufacturing methods. One of them is that after the insulating plastic is attached to the metal foil, the resist for forming the heating element pattern is screen-printed or photo-printed on the upper surface of the metal foil, and this is printed with a corrosive solution. After etching to make it float up, and further, after removing the resist film printed on the upper surface of this heating element pattern, a planar heating element with a resin film attached from the upper surface of this heating element pattern is known. Has been. However, when insert molding is performed using a sheet-like heating element having such a metal foil as a heating element pattern, there is a problem in that an electrically defective product is generated in the production process.
【０００５】 そこで、本考案者らはかかる問題を解決すべく分析してみると、Ｏ型の便座に あっては、ゲ−トが１箇所であってもウエルドラインが発生するし、更に馬蹄型 でも、Ｏ型の便座でも、生産性を上げるためや、樹脂の流れ抵抗を少なくするた めや、更に、樹脂の流路を短縮するために、複数のゲ−トを設ければ、これらの ゲ−トからの溶融樹脂の流動先端が合流して、ウエルドラインが発生する。その ため、これらのウエルドラインにおいて、成形時に、面状発熱体にシワが発生す ることがあった。一方、かかる金属箔からなる発熱素子パタ−ンは、折り曲げに 対し弱いという性質や、金属箔の発熱素子パタ−ンと樹脂フィルムとが合わされ てできた面状発熱体は、金型にセットするとき３次元状に弯曲されて伸ばされた 部分やシワの部分が生じ、しかも、溶融樹脂の流動に伴いフィルム面状発熱体に は伸縮する性質があるので、前記シワの部分で発熱素子パタ−ンが伸びたり、重 なり合ったりして電気的不都合が発生する、という問題を発見したのである。Therefore, the inventors of the present invention have made an analysis to solve such a problem. In the case of an O-type toilet seat, a weld line is generated even if there is only one gate, and further, a horseshoe. In order to improve productivity, reduce the flow resistance of the resin, and shorten the flow path of the resin, both of the mold and the O-shaped toilet seat can be provided with a plurality of gates. The welded lines are generated when the flow ends of the molten resin from the gate merge with each other. Therefore, in these weld lines, wrinkles may occur in the sheet heating element during molding. On the other hand, the heating element pattern made of such metal foil is weak against bending, and the sheet heating element made by combining the metal foil heating element pattern and the resin film is set in a mold. At this time, a portion which is curved and stretched in a three-dimensional manner and a wrinkle portion are generated, and moreover, the film-shaped heating element has the property of expanding and contracting as the molten resin flows. I discovered a problem in which electrical inconveniences occurred due to stretched and overlapping layers.
【０００６】 そのため、前掲の特開平３−７１８１５号公報で紹介されている提案のように 面状発熱体に多数の貫通孔を設けて突出されたゲ−トに挿入して固定しておき、 インサ−ト形成時の面状発熱体にシワを発生させないことも考えられるが、かか る場合、本来、ゲ−トの位置は射出成形を良好に行うために制約されているが、 この制約を面状発熱体の固定のために更に制約することとなって、金型の設計が 困難となり、しかも、面状発熱体に貫通孔を設ける際には、発熱素子パタ−ンを 切断するおそれがある、という未解決の問題があった。Therefore, as in the proposal introduced in the above-mentioned Japanese Patent Laid-Open No. 3-71815, a sheet heating element is provided with a large number of through holes and is inserted and fixed in a protruding gate, It is possible to prevent wrinkles from occurring in the sheet heating element during insert formation, but in such a case, the position of the gate is originally restricted in order to perform good injection molding. This further restricts the fixing of the sheet heating element, which makes it difficult to design the mold, and may cut the heating element pattern when forming a through hole in the sheet heating element. There was an unsolved problem that there was.
【０００７】[0007]
そこで本考案は、面状発熱体を内蔵した便座における、前記不都合を解消する ために案出されたもので、その要旨とするところは、第１の金型上に配置された 面状発熱体を、これと相対する第２の金型を合せてインサ−ト成形した後、該面 状発熱体の露出側を更に第３の金型によりインサ−ト成形した２層成形暖房便座 において、前記面状発熱体の発熱電極を金属箔からなる発熱素子で形成し、該発 熱素子の形状を印刷され、エッチングにより形成され、かつ、その主方向を樹脂 の流動方向としたパタ−ンとすると共に、該発熱素子パタ−ンの両面もしくは片 面を樹脂フィルムでラミネ−トし、該樹脂フィルムに、発熱素子パタ−ンを回避 し、かつ、前記金型のゲ−ト孔から可及的に離れた位置にカット部を設けたこと を特徴とする合成樹脂製洋式便器用の暖房便座にある。 Therefore, the present invention was devised in order to eliminate the above-mentioned inconvenience in a toilet seat having a sheet heating element built therein, and the gist thereof is a sheet heating element arranged on the first mold. In a two-layer molded heating toilet seat in which the second mold opposite to this is combined with insert molding, and the exposed side of the planar heating element is further insert-molded with the third mold. The heating electrode of the planar heating element is formed of a heating element made of metal foil, and the pattern of the heating element is formed by printing and etching, and its main direction is a resin flow direction. At the same time, both sides or one side of the heating element pattern is laminated with a resin film so as to avoid the heating element pattern on the resin film, and possible through the gate hole of the mold. A cut portion is provided at a position distant from the In the heating toilet seat for the resin-made toilet.

本考案の構成を添付図面に示す実施例により、詳細に述べる。 図１は本考案の実施例の模式図、図２は本実施例の成形金型の断面図、図３は 本実施例の便座の斜視図、図４は他の実施例の要部図である。 The structure of the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings. FIG. 1 is a schematic view of an embodiment of the present invention, FIG. 2 is a sectional view of a molding die of this embodiment, FIG. 3 is a perspective view of a toilet seat of this embodiment, and FIG. 4 is a main part view of another embodiment. is there.
【０００９】 本実施例は、馬蹄型や、Ｏ型のいずれの便座にも適用できるし、また、設置用 やポ−タブル用のいずれの洋式便器にも適用できるものである。The present embodiment can be applied to any horseshoe-shaped or O-shaped toilet seat, and can also be applied to any Western-style toilet bowl for installation or portable use.
【００１０】 先ず、周知の洋式便器の概要について述べると、図３において、便器本体１の 上面には、ヒンジ２を介して便座３が俯仰自在に取付けられており、この便座３ を起こして小便を、倒して腰をかけ大便を行うようになっている。そのため、便 座３にはヒ−タが内蔵され、特に冬場において腰かけたときの感触を良くしてい る。First, the outline of a known Western style toilet bowl will be described. In FIG. 3, a toilet seat 3 is attached to the upper surface of the toilet body 1 via a hinge 2 so as to be lifted and lowered, and the toilet seat 3 is raised to make a urine. It is supposed to be overturned and to sit down for stool. For this reason, the toilet seat 3 has a built-in heater to improve the feel when sitting down, especially in winter.
【００１１】 さて、このヒ−タ入りの便座３は、２層成形法により成形される。すなわち、 便座３は裏面本体と、この裏面本体を覆うカバ−表体との２層からなり、この２ 層間に後記の面状発熱体８が介装されている。したがって、先ず、裏面本体を射 出成形するには、例えば、図２のキャビ型４（これを本明細書では第１の金型と も称する）に面状発熱体８を熱活性接着剤を介して、セットし、更に、この面状 発熱体８をキャビ型４に穿設されたエア−引き孔５によって仮固定する。次いで 、このキャビ型４と、これと対向するコア型６（これを本明細書では第２の金型 とも称する）とを型締めして、コア型６のゲ−ト７から面状発熱体８を押圧する ように溶融樹脂を射出する。その結果、面状発熱体８がインサ−トされた裏面本 体が成形できる。 ここで、このゲ−ト７とエア−引き孔５との位置は、図１に示すようになって いる。Now, the toilet seat 3 with the heater is formed by a two-layer forming method. That is, the toilet seat 3 is composed of two layers of a back surface main body and a cover front body covering the back surface main body, and a planar heating element 8 described later is interposed between the two layers. Therefore, first, in order to perform the injection molding of the back surface main body, for example, the planar heating element 8 is attached to the cavity mold 4 (also referred to as the first mold in this specification) of FIG. Then, the sheet heating element 8 is temporarily fixed by an air-pulling hole 5 formed in the cavity mold 4. Next, the cavity mold 4 and the core mold 6 (which is also referred to as a second mold in the present specification) facing the mold mold 4 are clamped to each other from the gate 7 of the core mold 6 to the planar heating element. The molten resin is injected so as to press 8. As a result, it is possible to form a back surface body in which the sheet heating element 8 is inserted. Here, the positions of the gate 7 and the air drawing hole 5 are as shown in FIG.
【００１２】 かかる射出成形に当り、便座３の形状は、平面視で馬蹄形やＯ形になっている と共に、断面視で表面側がゆるやかなカマボコ状になっているので、キャビ型４ にセットされた面状発熱体８は３次元状に弯曲された形状となる。したがって、 面状発熱体８はセットされた時点で、すでにそのシ−ト状フィルムが伸ばされた り、シワができたりする。更に溶融樹脂で押圧されると、この状態が助勢される ので、電気的不良箇所を発生させることになる。そこで、本実施例の面状発熱体 ８には、ゲ−ト７より可及的に遠距離になる箇所（往々にして、前述のウエルド ラインが発生しやすい箇所）にＶ状カット部８ａを形成してみると意外にも、か かるシ−ト状フィルムのシワ等の過不足が吸収された。勿論、かかるＶ状カット 部８ａの箇所は、後記のヒ−タ−回路１０を避けている。 次いで、このキャビ型４を開いた後、裏面本体が取付けられているコア型６を 移動させて、図示しない第３の金型に合せる。そこで、裏面本体とカバ−表体と が一体成形される。また、別の方法として、このキャビ型４を開いた後、でき上 がった成形体を取り出し、第３の金型で別途インサ−ト成形を繰り返してもよい 。In this injection molding, the toilet seat 3 has a horseshoe shape or an O shape in a plan view, and the surface side has a gentle sickle shape in a sectional view, so that the toilet seat 3 is set in the mold type 4. The planar heating element 8 has a three-dimensional curved shape. Therefore, when the sheet heating element 8 is set, the sheet-shaped film is already stretched or wrinkled. If the molten resin is further pressed, this state is assisted, and an electrically defective portion is generated. Therefore, in the sheet heating element 8 of the present embodiment, a V-shaped cut portion 8a is provided at a position where the distance is as far as possible from the gate 7 (the above-mentioned weld line is likely to occur). Surprisingly, when the film was formed, excess and deficiency such as wrinkles of the sheet film was absorbed. Of course, such a V-shaped cut portion 8a avoids the heater circuit 10 described later. Next, after opening the cabinet mold 4, the core mold 6 to which the back surface main body is attached is moved to match the third mold (not shown). Therefore, the back body and the cover body are integrally molded. As another method, after opening the mold 4, the completed molded body may be taken out and insert molding may be repeated with a third mold.
【００１３】 ここにおいて、本実施例の面状発熱体８は次のようにして製造される。 すなわち、厚さ３０μ〜５０μのステンレス箔（ＳＵＳ３０４）と厚さ２５μ 〜５０μのの樹脂フィルム（２軸延伸ポリエステルフィルム）とを、接着剤を１ ０〜２０μの厚さに介在させてラミネ−トする。このように、ステンレス箔を薄 くして、かつ、表面積を多くすれば、より高温が得られると共に、薄い樹脂フィ ルムと相俟って、後工程のインサ−ト成形時の金型に対するフイット性が良くな る。 このステンレス箔に、ヒ−タ−回路１０、センサ−回路１１および端子１１ａ ，１２のパタ−ンを印刷してレジスト膜を作る。更にこれをエッチング処理する ことによりこれらの回路を形成する。この場合、ヒ−タ−回路１０、つまり発熱 素子パタ−ンの巾を１〜2.５mm、パタ−ンのピッチ３〜５mm、抵抗値２００〜２ ５０オ−ムとなるようにパタ−ンの全長を決める。そして、このパタ−ンの形状 は、主方向が便座３の周方向に沿うように形成して、樹脂の流動方向と一致させ ている。しかも、インサ−ト成形時に流動樹脂の合流位置にあたる箇所（ウエル ドライン）にはヒ−タ−回路１０を回避させ、巾２０〜５０mmのＶ状カット部８ ａを形成する。その結果、面状発熱体８は、後工程のインサ−ト成形時に樹脂の 流れ方向への剛性が高められシワが生じないようになる。 また、センサ−回路１１の接続側端子１１ａ、およびヒ−タ−回路１０の温度 ヒュ−ズ接続部端子１０ａは、便座３の脚ゴム４ａ，４ｂの設置孔に位置させる とよい。Here, the sheet heating element 8 of the present embodiment is manufactured as follows. That is, a stainless foil (SUS304) having a thickness of 30 μ to 50 μ and a resin film (biaxially stretched polyester film) having a thickness of 25 μ to 50 μ are made to intervene with an adhesive to a thickness of 10 to 20 μ, and a laminate is formed. To do. In this way, by making the stainless steel foil thin and increasing the surface area, higher temperature can be obtained, and in combination with the thin resin film, the fit property to the mold at the time of insert molding in the subsequent process is improved. Will improve. A pattern of the heater circuit 10, the sensor circuit 11 and the terminals 11a and 12 is printed on this stainless steel foil to form a resist film. Further, these circuits are etched to form these circuits. In this case, the heater circuit 10, that is, the heating element pattern has a width of 1 to 2.5 mm, a pattern pitch of 3 to 5 mm, and a resistance value of 200 to 250 ohms. Determine the total length of. The shape of this pattern is formed so that the main direction is along the circumferential direction of the toilet seat 3, and is matched with the resin flow direction. In addition, the heater circuit 10 is avoided at the location (weld line) corresponding to the confluence position of the fluid resin during insert molding, and the V-shaped cut portion 8a having a width of 20 to 50 mm is formed. As a result, the sheet heating element 8 has increased rigidity in the resin flow direction during insert molding in the subsequent step, and wrinkles do not occur. Further, the connection side terminal 11a of the sensor circuit 11 and the temperature fuse connecting portion terminal 10a of the heater circuit 10 may be located in the installation holes of the leg rubbers 4a and 4b of the toilet seat 3.
【００１４】 以上のような発熱素子パタ−ンを備えた面状発熱体８を使用して便座３を射出 成形してみたところ、意外にも、発熱素子パタ−ンにシワや切断が発生せず、生 産工程における電気的不良品が減少できた。 なお、本実施例のヒ−タ−回路１０は一連に構成されているので、Ｖ状カット 部８ａは、このヒ−タ−回路１０を避けるように形成されているが、ヒ−タ−回 路１０を１対のもので構成すれば、図４に示すようなカット部８ｂに形成しても よい。When the toilet seat 3 is injection-molded using the sheet heating element 8 having the above-described heating element pattern, surprisingly, the heating element pattern is wrinkled or cut. Therefore, the number of electrically defective products in the production process could be reduced. Since the heater circuit 10 of this embodiment is constructed in a series, the V-shaped cut portion 8a is formed so as to avoid the heater circuit 10, but the heater circuit is If the path 10 is composed of one pair, it may be formed in the cut portion 8b as shown in FIG.
【００１５】[0015]
本考案によれば、面状発熱体に、ヒ−タ回路を避け、かつ、金型のゲ−ト孔よ り遠い位置にカット部を作ったので、面状発熱体にシワや切断が発生せず、しか も発熱素子パタ−ンの主方向を樹脂の流れに沿うようにしたので、発熱素子パタ −ンの折り曲げを回避して、断線やショ−トを防止することができる。 According to the present invention, since the cut portion is formed in the sheet heating element at a position away from the heater circuit and farther than the gate hole of the mold, wrinkles and cuts occur in the sheet heating element. However, since the main direction of the heating element pattern is made to follow the flow of the resin, it is possible to avoid bending of the heating element pattern and prevent disconnection or short.
