しかしながら、前記従来の構成では、サーミスタは凹部に感熱部を暴露した状態ではめ込んで固定させたものであるため、サーミスタの感熱部は便座の上ケースの温度を感知すると共に、下方に配置したランプヒータからの輻射エネルギの影響を受け、実際の便座の上ケースの温度より高い温度を検知することとなり、上ケースの温度が十分に昇温する前に便座の温度を制御することとなり、結果として正しく便座の温度制御ができず、そのため快適な暖房便座を提供することができないという課題を有していた。   However, in the above-described conventional configuration, the thermistor is fitted and fixed in a state where the heat sensitive part is exposed to the recess, so that the heat sensitive part of the thermistor senses the temperature of the upper case of the toilet seat and is disposed below the lamp. Under the influence of the radiant energy from the heater, a temperature higher than the actual temperature of the upper case of the toilet seat will be detected, and the temperature of the toilet seat will be controlled before the temperature of the upper case rises sufficiently. There was a problem that the temperature of the toilet seat could not be controlled correctly, and therefore a comfortable heated toilet seat could not be provided.

本発明は、前記従来の課題を解決するもので、サーミスタに対するランプヒータの輻射エネルギの影響を軽減し、便座の温度を正確に検知することにより、快適な暖房便座を提供することを目的とする。   The present invention solves the above-described conventional problems, and an object thereof is to provide a comfortable heating toilet seat by reducing the influence of the radiant energy of the lamp heater on the thermistor and accurately detecting the temperature of the toilet seat. .

(Embodiment 1)
FIG. 1 shows a perspective view of the entire heated toilet seat according to Embodiment 1 of the present invention, FIG. 2 shows a perspective view of the toilet seat, FIG. 3 shows a bottom view of a part of the lower body of the toilet seat, and FIG. FIG. 5 is a sectional view of the thermistor fixing structure portion in the toilet seat, FIG. 5 is a perspective view of the internal structure of the lower body of the toilet seat, and FIG. 6 is a detailed perspective view of the holding body.

図に示すように、本実施の形態における暖房便座は、後方に設置した樹脂製の外装を備えた本体1に、上下方向に開閉自在な便座2と便蓋3が枢支してある。便座2の内部には便座2を暖房、保温する発熱体としてランプヒータ4が組み込んである。また、本体1の内部には局部を洗浄する局部洗浄手段(図示せず)と前記便座2を加熱するランプヒータ4や局部洗浄手段を制御する制御手段(図示せず)が設置してある。   As shown in the drawing, in the heating toilet seat according to the present embodiment, a toilet seat 2 and a toilet lid 3 that are openable and closable in the vertical direction are pivotally supported on a main body 1 having a resin exterior installed at the rear. A lamp heater 4 is incorporated in the toilet seat 2 as a heating element for heating and keeping the toilet seat 2 warm. Further, a local cleaning means (not shown) for cleaning the local part and a lamp heater 4 for heating the toilet seat 2 and a control means (not shown) for controlling the local cleaning means are installed inside the main body 1.

便座2は金属製の上部体5と樹脂製の下部体6を上下に接合し、内部に空洞部を形成した構成となっている。図3は便座2を下方から見た下面図を示したものであり、左半分を便座2の下部体6のある状態、右半分は便座2の下部体6の無い状態を示すものであり、右半分で示された上部体5の内面には、便座表面の温度検出用サーミスタ7が被覆体8にて固定してある。被覆体8はアルミ箔の裏面に粘着剤を付帯した構成となっており、サーミスタ7は被覆体8のみで仮止め状態として保持可能である。   The toilet seat 2 has a configuration in which a metal upper body 5 and a resin lower body 6 are joined vertically to form a hollow portion inside. FIG. 3 shows a bottom view of the toilet seat 2 as viewed from below. The left half shows a state where the lower body 6 of the toilet seat 2 is present, and the right half shows a state where the lower body 6 of the toilet seat 2 is absent. On the inner surface of the upper body 5 shown by the right half, a temperature detection thermistor 7 on the toilet seat surface is fixed by a covering 8. The cover 8 has a configuration in which an adhesive is attached to the back surface of the aluminum foil, and the thermistor 7 can be held in a temporarily fixed state only by the cover 8.

一方、図5に示すように下部体6の内部には、下部体6の略全周に亘ってアルミ板で形成した反射板9が設置してあり、反射板9の上方には、略U字形の2本のランプヒータ4が便座2の全周に亘って固定部材10を介して設置してあり、ランプヒータ4はリード線11にて本体1の内部に設置した制御手段と接続し電力が供給されるよう形成してある。ランプヒータ4は石英管の中央部を貫通するようにフィラメントを配置し、石英管内部に不活性ガスを封入したものである。   On the other hand, as shown in FIG. 5, a reflecting plate 9 formed of an aluminum plate is installed around the entire circumference of the lower body 6 inside the lower body 6. Two letter-shaped lamp heaters 4 are installed over the entire circumference of the toilet seat 2 via a fixing member 10, and the lamp heater 4 is connected to a control means installed inside the main body 1 by a lead wire 11 to be connected to electric power. Is configured to be supplied. The lamp heater 4 has a filament disposed so as to penetrate the center of the quartz tube, and an inert gas is sealed inside the quartz tube.

そして、便座2の上部体5に固定してあるサーミスタ7のちょうど真下の位置となる反射板9の所定位置には、サーミスタ7を保持する被覆体8を挟持する挟持体12が取付ねじ13で固定してある。   At a predetermined position of the reflector 9 that is just below the thermistor 7 fixed to the upper body 5 of the toilet seat 2, a clamping body 12 that clamps the covering 8 that holds the thermistor 7 is attached by an attachment screw 13. It is fixed.

挟持体12は、便座組立状態において、上部体5と下部体6とに無理な力が働かず、かつサーミスタ7を保持する被覆体8を安定して挟持するため、またランプヒータ4からの熱的な影響を直接受けにくくするため、弾力性を備えた細い金属の線材を曲げて形成したもので、特に弾力性を増すために元の部分を螺旋状に形成したものであり、便座2への荷重による撓み変形も吸収しやすくなっている。また、サーミスタ7を固定している被覆体8を挟持する部分は略コ字形状に形成してあり、被覆体8の外周近傍を挟持できる構成となっている。これにより、衝撃に弱いサーミスタ7を直接挟持体12で押さえ込むのではなく、被覆体8の周辺近傍を押さえる構造とすることで、サーミスタ7の故障や誤検知を防ぐことができる。   The clamping body 12 does not exert excessive force on the upper body 5 and the lower body 6 in the toilet seat assembly state, and stably holds the covering body 8 that holds the thermistor 7. In order to make it less susceptible to direct influence, it is formed by bending a thin metal wire with elasticity, and in particular, the original part is formed in a spiral to increase elasticity. It is easy to absorb the bending deformation caused by the load. In addition, a portion for sandwiching the covering 8 that fixes the thermistor 7 is formed in a substantially U shape, and the vicinity of the outer periphery of the covering 8 can be sandwiched. Thereby, the thermistor 7 which is weak against impact is not directly pressed by the sandwiching body 12, but a structure in which the vicinity of the periphery of the covering body 8 is pressed can prevent the thermistor 7 from being broken or erroneously detected.

便座2の組立過程においては、便座2の上部体5にサーミスタ7を被覆体8で仮止め状態とし、下部体6の反射板9に挟持体12を固定した状態で、上部体5と下部体6を嵌合することにより、挟持体12が被覆体8の周辺近傍を挟持する状態となり、サーミスタ7を上部体5の裏面に確実に取り付けることができる。   In the process of assembling the toilet seat 2, the thermistor 7 is temporarily attached to the upper body 5 of the toilet seat 2 with the cover 8, and the sandwiching body 12 is fixed to the reflector 9 of the lower body 6. By fitting 6, the sandwiching body 12 is in a state of sandwiching the vicinity of the periphery of the covering body 8, and the thermistor 7 can be securely attached to the back surface of the upper body 5.

また、上記構成のように、発熱体が輻射型発熱体であるランプヒータ4の場合、サーミスタ7を固定している粘着剤を付帯した被覆体8を輻射エネルギを反射しやすいアルミ箔で構成したことにより、ランプヒータからの直接の吸熱は少なくなり、サーミスタは便座2の上部体5の温度を正確に検知することができる。 In the case of the lamp heater 4 in which the heating element is a radiant heating element as in the above configuration, the covering 8 attached with the adhesive fixing the thermistor 7 is made of an aluminum foil that easily reflects the radiant energy. Thus, the direct heat absorption from the lamp heater 4 is reduced, and the thermistor can accurately detect the temperature of the upper body 5 of the toilet seat 2.

以上のように、本実施の形態においては、上部体の裏面に密着したサーミスタに被覆体を被装し、前記被覆体の周辺部を弾力性を有する挟持体で挟持することにより、便座のサーミスタは、便座の上部体に密着すると共に、発熱体に対向する下方側は被覆体で覆われるため、発熱体からの直接伝わる熱の影響を軽減することができるため、便座の温度を正確に検知することができるものである。
なお、本実施の形態における発熱体はランプヒータを採用したがこれに限るものではなく、シーズヒータや可撓性のあるヒータ線等の発熱体で構成しても同様の効果を得ることができる。
As described above, in the present embodiment, the thermistor of the toilet seat is formed by covering the thermistor in close contact with the back surface of the upper body and sandwiching the periphery of the covering body with the elastic sandwiching body. Is close to the upper body of the toilet seat, and the lower side facing the heating element is covered with a covering, which can reduce the influence of heat directly transmitted from the heating element, so the temperature of the toilet seat can be accurately detected Is something that can be done.
The heating element in the present embodiment employs a lamp heater, but the present invention is not limited to this, and the same effect can be obtained even if it is composed of a heating element such as a sheathed heater or a flexible heater wire. .

また、本実施の形態においては、挟持体は細い金属の線材で形成したが、これに限るものではなく、板状の金属や耐熱性を備えた樹脂等で形成することも可能である。   In the present embodiment, the sandwiching body is formed of a thin metal wire, but is not limited thereto, and can be formed of a plate-shaped metal or a resin having heat resistance.

また、本実施の形態においては、挟持体を独立した部材として反射板に固定した構成としたが、これに限るものではなく、反射板の一部を切り起こして反射板と一体で構成することにより、部材の点数を減らすことができ、組立時の手間を省くことが可能となる。   Moreover, in this Embodiment, it was set as the structure which fixed the clamping body to the reflecting plate as an independent member, However, It is not restricted to this, A part of reflecting plate is cut and raised and it is comprised integrally with a reflecting plate. As a result, the number of members can be reduced, and the time and labor during assembly can be saved.

また、本実施の形態においては、挟持体を下部体に設置した反射板に設置したが、これに限るものではなく、下部の他の部分や上部体に設置することも可能である。 Moreover, in this Embodiment, although the clamping body was installed in the reflecting plate installed in the lower body , it is not restricted to this, It is also possible to install in the other part and upper body of a lower body .

以上のように、本発明にかかる暖房便座は、人体が接する構造体の温度を正確に検知するサーミスタの固定方法であるので、暖房便座のみならず、人体に直接接触させて使用する採暖器具等の用途にも適用できるものと考えられる。 As described above, since the heating toilet seat according to the present invention is a thermistor fixing method that accurately detects the temperature of the structure in contact with the human body, not only the heating toilet seat, but also a heating instrument that is used in direct contact with the human body, etc. It is considered that it can be applied to other uses.
