Description
本発明は、複雑な部材を使用せずに便座表面温度を均熱化した便座装置に関するものである。 The present invention relates to a toilet seat device in which the toilet seat surface temperature is equalized without using a complicated member.
従来この種の便座装置は、輻射反射板を用いて均熱化を図っている（例えば、特許文献１参照）。 Conventionally, this type of toilet seat device achieves soaking by using a radiation reflector (see, for example, Patent Document 1).
図５は、前記公報に記載された従来の便座装置を示すものである。図５に示すように、空洞部１の内部には便座２の便座上部３に対向して、アルミ板を鏡面仕上げした輻射反射板４と輻射型発熱体５から構成されている。
しかしながら、前記従来の構成では、アルミ板の輻射反射板を折り曲げて均熱化を図っているので、便座が重くなるという課題を有していた。 However, the conventional configuration has a problem that the toilet seat becomes heavy because the aluminum plate radiation reflector is bent to achieve uniform temperature.
本発明は、前記従来の課題を解決するもので、軽量で均熱化した便座装置を提供することを目的とする。 An object of the present invention is to solve the above-mentioned conventional problems and to provide a toilet seat device that is lightweight and has a uniform temperature.
前記従来の課題を解決するために、本発明の便座装置は、内部に空洞部が形成された便座と、前記空洞部に設けられた輻射型発熱体とを有し、前記輻射型発熱体と上方の便座内壁面との距離に応じて前記輻射型発熱体の発熱部の配設密度に粗密を設けて形成したものである。 In order to solve the above-described conventional problems, a toilet seat device of the present invention includes a toilet seat in which a cavity is formed, and a radiation-type heating element provided in the cavity, the radiation-type heating element, According to the distance from the upper inner wall surface of the toilet seat, the density of the heat generating portions of the radiant type heat generating element is provided with a rough density.
これによって、余分な部材を使用しないため、便座表面温度の均熱化が軽量で可能となる。 Accordingly, since no extra member is used, the temperature of the toilet seat surface can be equalized with light weight.
本発明の便座装置は、便座表面温度の均熱化を少ない部材で軽量で実現することができる。 The toilet seat device of the present invention can achieve uniform temperature control of the toilet seat surface temperature with a small number of members.
第１の発明は、内部に空洞部が形成された便座と、前記空洞部に設けられた輻射型発熱体とを有し、前記輻射型発熱体と上方の便座内壁面との距離に応じて前記輻射型発熱体の発熱部の配設密度に粗密を設けて形成したことにより、輻射型発熱体と上方の便座内壁面との距離が大きい部分は発熱部の配設密度を密にすることにより便座内壁面への輻射エネルギーの供給を相対的に高めることができ、これに対して輻射型発熱体と上方の便座内壁面との距離が小さい部分は発熱部の配設密度を粗にすることにより便座内壁面への輻射エネルギーの供給を相対的に少なくすることができるので、輻射型発熱体と上方の便座内壁面との距離に応じて発熱部の配設密度に粗密を設けることにより、便座全体の表面温度を均熱化することができる。 1st invention has the toilet seat in which the cavity part was formed in the inside, and the radiation type heat generating body provided in the said cavity part, According to the distance of the said radiation type heating element and the toilet seat inner wall surface above By forming the heat generating portions of the radiant heating element in a dense arrangement, the heat generating portions are arranged densely in a portion where the distance between the radiant heating element and the upper inner wall surface of the toilet seat is large. Can relatively increase the supply of radiant energy to the inner wall surface of the toilet seat. On the other hand, the portion where the distance between the radiant heating element and the upper inner wall surface of the toilet seat is small roughens the arrangement density of the heat generating parts. Therefore, it is possible to relatively reduce the supply of radiant energy to the inner wall surface of the toilet seat, so that the density of the heat generating parts can be increased or decreased according to the distance between the radiant heating element and the upper inner wall surface of the toilet seat. The surface temperature of the entire toilet seat can be equalized.
第２の発明は、特に、第１の発明の便座後方部の輻射型発熱体と便座内壁面との距離を、他の部分より小さく形成し、便座後方の輻射型発熱体の発熱部を、他の部分に比べ粗に形成することにより、便座後方部の便座内壁面への輻射エネルギーの供給を相対的に少なくすることとなり、便座の他の部分と表面温度を均一にすることができる。 In the second invention, in particular, the distance between the radiant heating element at the rear part of the toilet seat and the inner wall surface of the toilet seat of the first invention is made smaller than the other parts, and the heating part of the radiant heating element behind the toilet seat is provided, By forming it roughly as compared with other portions, the supply of radiant energy to the inner surface of the toilet seat at the rear portion of the toilet seat is relatively reduced, and the surface temperature can be made uniform with other portions of the toilet seat.

An infrared transmitting part is provided on the sleeve 7a of the main body 7, and the presence or absence of a human body in the toilet space is detected on the inner side. An infrared sensor 10 is incorporated.
次に図２及び図３に示すように、便座９は、合成樹脂製の上ケース１１と下ケース１２のそれぞれの内周縁および外周縁を接合固定することにより、内部に空洞部１３を有する構造となっている。その空洞部１３の内部には上ケース１１の便座内壁面１４に対向して、輻射型発熱体であるランプヒータ１６が設けられている。ランプヒータ１６の近傍には、ランプヒータ１６と直列に電気接続したサーモスタット１７及び温度ヒューズ１８が設けられ、万一の不安全事態に対して温度過昇を防止するよう作用する。 Next, as shown in FIGS. 2 and 3, the toilet seat 9 has a structure having a hollow portion 13 by bonding and fixing the inner peripheral edge and the outer peripheral edge of the upper case 11 and the lower case 12 made of synthetic resin. It has become. A lamp heater 16, which is a radiant heating element, is provided inside the hollow portion 13 so as to face the toilet seat inner wall surface 14 of the upper case 11. A thermostat 17 and a thermal fuse 18 that are electrically connected in series with the lamp heater 16 are provided in the vicinity of the lamp heater 16 and act to prevent an overtemperature in the event of an unsafe situation.
また、上ケース１１の内面に設けられた凹部にはサーミスタ１９がはめ込まれており、このサーミスタ１９の信号に基づいて便座９の表面温度が所定の温度になるようランプヒータ１６への通電を制御する制御器（図示せず）が本体７に設けられている。 In addition, a thermistor 19 is fitted in a recess provided in the inner surface of the upper case 11, and the energization of the lamp heater 16 is controlled based on a signal from the thermistor 19 so that the surface temperature of the toilet seat 9 becomes a predetermined temperature. The main body 7 is provided with a controller (not shown).
図４（ａ）は便座９の側方部２０の断面を示し、（ｂ）は便座９の後方部２１の断面を示すものであり、図のようにランプヒータ１６と上ケース１１の便座内壁面１４との距離は側方部２０より後方部２１の方が短くなっている。 4 (a) shows a cross section of the side portion 20 of the toilet seat 9, and FIG. 4 (b) shows a cross section of the rear portion 21 of the toilet seat 9. As shown in the figure, the inside of the toilet seat of the lamp heater 16 and the upper case 11 is shown. The distance from the wall surface 14 is shorter in the rear part 21 than in the side part 20.
図５に示すように、ランプヒータ１６は石英管２２の中に、発熱部として螺旋状に形成したタングステンフィラメント２３の要所をハンガー２４で支持して、石英管２２の略中央に配置してあり、アルゴンと窒素を主成分としたガスを封入してある。 As shown in FIG. 5, the lamp heater 16 is arranged in the quartz tube 22 with the hanger 24 supporting the main part of the tungsten filament 23 formed in a spiral shape as a heat generating portion, and arranged at the approximate center of the quartz tube 22. Yes, a gas mainly composed of argon and nitrogen is enclosed.
螺旋状に形成したタングステンフィラメント２３は螺旋のピッチを広くした配設密度が粗の部分２３ａと、螺旋のピッチを狭くした配設密度が密の部分２３ｂが便座内壁面１４との距離に対応して形成してあり、側方部２０では配設密度を密に形成してあり、後方部２１では粗に形成してある。 The spirally formed tungsten filament 23 corresponds to the distance from the toilet seat inner wall surface 14 to a portion 23a having a coarse arrangement density with a wide helical pitch and a portion 23b having a narrow arrangement density having a narrow helical pitch. The side portion 20 is densely arranged, and the rear portion 21 is coarsely formed.
以上のように構成された便座装置について、以下その動作、作用を説明する。 About the toilet seat apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
まず、使用者がトイレに入室した場合、赤外線センサ１０がそれを検知し、その信号により輻射型発熱体１６が付勢される。これにより投入エネルギーは瞬時に輻射エネルギーに変換され、上ケース１１の方向に放射され、上ケース１１をほぼ瞬時に加温することができるものである。 First, when the user enters the toilet, the infrared sensor 10 detects this, and the radiation heating element 16 is energized by the signal. As a result, the input energy is instantaneously converted into radiant energy and radiated in the direction of the upper case 11 so that the upper case 11 can be heated almost instantaneously.
また、ランプヒータ１６から便座内壁面１４への距離の近い便座９の側方部２０と、ランプヒータ１６から便座内壁面１４への距離の遠い便座９の後方部２１にはともに輻射エネルギーが伝わり便座９を昇温するが、ランプヒータ１６の便座９の側方部２０に配設した部分は便座９の後方部２１に配設した部分よりタングステンフィラメント２３は螺旋のピッチを狭くし配設密度を密にしているため輻射エネルギーが相対的に多く放射するため便座９側方部の温度が上昇しやすくなり、結果的に便座９の表面温度が均一となる。 Radiation energy is transmitted to both the side portion 20 of the toilet seat 9 where the distance from the lamp heater 16 to the toilet seat inner wall surface 14 is short and the rear portion 21 of the toilet seat 9 which is far from the lamp heater 16 to the toilet seat inner wall surface 14. Although the temperature of the toilet seat 9 is increased, the portion disposed in the side portion 20 of the toilet seat 9 of the lamp heater 16 has a narrower helical pitch than the portion disposed in the rear portion 21 of the toilet seat 9 and the density of the tungsten filament 23 is reduced. Since the radiant energy is relatively radiated, the temperature of the side portion of the toilet seat 9 is likely to rise, and as a result, the surface temperature of the toilet seat 9 becomes uniform.
以上のように、本実施の形態においては、便座側方部のランプヒータと便座内壁面との距離を後方部より大きく形成し、便座側方部のランプヒータのタングステンフィラメントを後方部に比べ密に形成することにより、便座全体の表面温度を均一にすることができる。 As described above, in this embodiment, the distance between the lamp heater on the side of the toilet seat and the inner wall surface of the toilet seat is formed larger than the rear part, and the tungsten filament of the lamp heater on the side of the toilet seat is more dense than the rear part. By forming in, the surface temperature of the whole toilet seat can be made uniform.
なお、本実施の形態においては便座の後方部において便座の側方部よりランプヒータを便座内壁面に短い距離で配設したが、これに限るものではなく便座のいずれの場所においてもランプヒータと便座内壁面との距離を任意に設定し、それに対応してランプヒータのタングステンフィラメントの螺旋のピッチを変更することにより便座の表面温度を均一にすることが可能である。 In this embodiment, the lamp heater is disposed on the inner wall surface of the toilet seat at a short distance from the side of the toilet seat at the rear portion of the toilet seat. However, the present invention is not limited to this, and the lamp heater can be used at any location on the toilet seat. It is possible to make the surface temperature of the toilet seat uniform by arbitrarily setting the distance from the inner wall surface of the toilet seat and changing the pitch of the tungsten filament spiral of the lamp heater accordingly.
また、タングステンフィラメントの螺旋のピッチは複数のピッチを連続的に形成することが可能であり、ランプヒータと便座内壁面との複数の距離に対して連続的に対応することができる。 Moreover, the pitch of the spiral of the tungsten filament can be continuously formed with a plurality of pitches, and can continuously correspond to a plurality of distances between the lamp heater and the inner wall surface of the toilet seat.
以上のように、本発明にかかる便座装置は、便座表面温度の均熱化を少ない部材で軽量で実現することができるので、他の暖房器具等の用途にも適用できる。 As described above, the toilet seat device according to the present invention can be realized by reducing the temperature of the toilet seat surface temperature with a small number of members and can be applied to other uses such as a heating appliance.
