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４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４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。
特開２０００−０１４５９８号公報 FIG. 4 shows a conventional toilet seat device described in the publication. As shown in FIG. 4, the interior of the cavity portion 1 is composed of a radiation reflecting plate 4 having a mirror finished aluminum plate and a radiation type heating element 5 facing the toilet seat upper portion 3 of the toilet seat 2.
JP 2000-014598 A

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、内部に空洞部を形成した便座と、前記空洞部に配設された輻射型発熱体とを備え、前記輻射型発熱体上方の便座内壁面に格子状リブを形成したものである。 In order to solve the above-described conventional problems, a toilet seat device according to the present invention includes a toilet seat having a hollow portion formed therein, and a radiant heating element disposed in the hollow portion. A grid-like rib is formed on the inner wall surface of the toilet seat.

これによって、余分な材料を使用しないため、軽量で均熱化が可能となる。 As a result, since no extra material is used, it is possible to achieve a uniform temperature 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、内部に空洞部を形成した便座と、前記空洞部に配設された輻射型発熱体とを備え、前記輻射型発熱体上方の便座内壁面に格子状リブを形成したことにより、格子状リブが輻射エネルギーを吸収することにより便座の表面温度を調整することが可能となるため、輻射型発熱体と便座内面壁との距離に応じて、格子リブの配設密度を調整することにより、別の部品を追加することなく便座の表面温度を均一にすることができる。 1st invention provided the toilet seat which formed the cavity part inside, and the radiation type heat generating body arrange | positioned in the said cavity part, and formed the grid | lattice-like rib in the toilet seat inner wall surface above the said radiation type heat generating body This makes it possible to adjust the surface temperature of the toilet seat by the grid ribs absorbing the radiation energy, so the density of the grid ribs is adjusted according to the distance between the radiation heating element and the inner wall of the toilet seat. By doing so, the surface temperature of the toilet seat can be made uniform without adding another part.

第２の発明は、特に、第１の発明の輻射型発熱体を少なくとも便座の側方部と後方部に配設し、前記便座の後方部に比べ側方部に格子状リブを密に配設したことにより、輻射型発熱体と便座内壁面との距離が離れている後方部は格子状リブの密度を粗になり、格子状リブによる輻射エネルギーの吸収が少なく相対的に便座の表面温が上昇しやすくなり、これに対し輻射型発熱体と便座内壁面との距離が近い側方部は格子状リブの密度が密となることで、格子状リブによる輻射エネルギーの吸収が多くなり相対的に便座の表面温が上昇し難くなり、輻射型発熱体と便座内壁面との距離が異なる便座の側方部と後方部の表面温度を均一にすることができる。 In the second invention, in particular, the radiation-type heating element of the first invention is disposed at least on the side part and the rear part of the toilet seat, and the grid-like ribs are more closely arranged on the side part than the rear part of the toilet seat. As a result, the density of the grid ribs becomes rough at the rear part where the distance between the radiation heating element and the inner wall surface of the toilet seat is increased, and the surface temperature of the toilet seat is relatively less absorbed by the grid ribs. On the other hand, the side of the side where the distance between the radiant heating element and the inner wall surface of the toilet seat is short, the density of the grid ribs is high, and the absorption of radiation energy by the grid ribs increases. In particular, the surface temperature of the toilet seat is unlikely to rise, and the surface temperatures of the side and rear portions of the toilet seat in which the distance between the radiant heating element and the inner wall surface of the toilet seat are different can be made uniform.

第３の発明は、特に、第１の発明の輻射型発熱体を少なくとも便座の側方部と後方部に配設し、前記便座の後方部に比べ側方部の格子状リブの高さを高く形成したことにより、輻射型発熱体と便座内壁面との距離が離れている後方部は格子状リブの高さが低いため、格子状リブによる輻射エネルギーの吸収が少なく相対的に便座の表面温度が上昇しやすくなり、これに対し輻射型発熱体と便座内壁面との距離が近い側方部は格子状リブの高さが高いため、格子状リブによる輻射エネルギーの吸収が多くなり相対的に便座の表面温が上昇し難くなり、輻射型発熱体と便座内壁面との距離が異なる便座の側方部と後方部の表面温度を均一にすることができる。 In particular, the radiation heater according to the first aspect of the present invention is disposed at least at the side and rear portions of the toilet seat, and the height of the grid-like ribs at the side portions is higher than the rear portion of the toilet seat. Since the height of the grid rib is low in the rear part where the distance between the radiation heating element and the inner wall surface of the toilet seat is high, the surface of the toilet seat is relatively less absorbed by the grid rib. The temperature tends to rise, and on the other hand, the height of the grid ribs is high in the side part where the distance between the radiant heating element and the inner wall of the toilet seat is high, so the absorption of radiation energy by the grid ribs increases and the relative height increases. In addition, it becomes difficult for the surface temperature of the toilet seat to rise, and the surface temperatures of the side portion and the rear portion of the toilet seat having different distances between the radiation-type heating element and the inner wall surface of the toilet seat can be made uniform.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、本実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment.

（実施の形態１）
図１は本発明の第１の実施の形態における便座装置を便器に設置した状態の斜視図を示し、図２は便座の一部断面を含む平面図を示し、図３は便座の側方部の要部断面図を示すものである。 (Embodiment 1)
FIG. 1 shows a perspective view of the toilet seat device according to the first embodiment of the present invention installed in a toilet, FIG. 2 shows a plan view including a partial cross section of the toilet seat, and FIG. 3 shows a side portion of the toilet seat. The principal part sectional drawing of is shown.

図１に示すように、便器６上に本体７が載置固定してある。前記本体７には回動自在に便蓋８及び便座９が設けてあり、前記本体７の袖部７ａには赤外線透過部が設けてあり、その内側にはトイレ空間の人体の有無を検知する赤外線センサ１０が内蔵されている。 As shown in FIG. 1, a main body 7 is placed and fixed on the toilet bowl 6. The main body 7 is provided with a toilet lid 8 and a toilet seat 9 so as to be rotatable. 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 built in.

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１６が設けられている。輻射型発熱体１６の近傍には、輻射型発熱体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 radiation heating element 16 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 radiant heating element 16 are provided in the vicinity of the radiant heating element 16, and act to prevent overheating 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輻射型発熱体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。 Further, a thermistor 19 is fitted in a recess provided on the inner surface of the upper case 11, and the radiation heating element 16 is energized so that the surface temperature of the toilet seat 9 becomes a predetermined temperature based on a signal from the thermistor 19. The main body 7 is provided with a controller (not shown) for controlling the above.

上ケース１１の便座内壁面１４には、格子状リブ２０が上ケース１１と一体に成型してある。格子状リブ２０は略円周方向配設した円周リブ２１と略法線方向の法線リブ２２から形成してあり、図２に示すように、便座９の側方部２３には法線リブ２２を多く配設することにより格子状リブ２０の密度を密にしており、これに対し、便座の後方部２４には法線リブ２２を少なく配設することにより格子状リブ２０の密度を粗にしている。 On the toilet seat inner wall surface 14 of the upper case 11, lattice ribs 20 are molded integrally with the upper case 11. The grid-like ribs 20 are formed by circumferential ribs 21 arranged in a substantially circumferential direction and normal ribs 22 in a substantially normal direction, and as shown in FIG. The density of the grid-like ribs 20 is increased by arranging a large number of ribs 22. On the other hand, the density of the grid-like ribs 20 is reduced by arranging fewer normal ribs 22 in the rear portion 24 of the toilet seat. It is rough.

図２は便座９の側方部２３の断面を示すものであり輻射型発熱体１６と便座内壁面１４との距離が小さくなっている。これに対し図示していないが便座９の後方部２４においては輻射型発熱体１６と便座内壁面１４との距離が大きくなっている。 FIG. 2 shows a cross section of the side portion 23 of the toilet seat 9, and the distance between the radiant heating element 16 and the toilet seat inner wall surface 14 is reduced. On the other hand, although not shown, the distance between the radiant heating element 16 and the toilet seat inner wall surface 14 is large in the rear portion 24 of the toilet seat 9.

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、便座内壁面１４の方向に放射され、便座９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. Thus, the input energy is instantaneously converted into radiant energy and radiated in the direction of the toilet seat inner wall surface 14 so that the toilet seat 9 can be heated almost instantaneously.

輻射型発熱体１６から便座内壁面１４への距離の近い便座９の側方部２３と、輻射型発熱体１６から便座内壁面１４への距離の遠い便座９の後方部２４に輻射エネルギーが伝わり便座９を昇温するが、便座９の側方部２３の格子状リブ２０を便座９の後方部２４の格子状リブに比べて密に配設したことにより、格子状リブで輻射エネルギーを吸収してしまうため相対的に便座の表面温が上昇し難くなり、便座９の側方部２３と後方部２４の表面温度が均一となる。 Radiation energy is transmitted to the side portion 23 of the toilet seat 9 where the distance from the radiation-type heating element 16 to the toilet seat inner wall surface 14 is short, and the rear portion 24 of the toilet seat 9 which is far from the radiation-type heating element 16 to the toilet seat inner wall surface 14. Although the temperature of the toilet seat 9 is increased, the grid-like ribs 20 on the side portions 23 of the toilet seat 9 are arranged more densely than the grid-like ribs on the rear portion 24 of the toilet seat 9, so that the grid-like ribs absorb the radiation energy. Therefore, the surface temperature of the toilet seat becomes relatively difficult to rise, and the surface temperatures of the side portion 23 and the rear portion 24 of the toilet seat 9 become uniform.

以上のように、本実施の形態においては、輻射型発熱体から便座内壁面１４への距離の近い便座の側方部と、輻射型発熱体から便座内壁面１４への距離の遠い便座の後方部の、格子状リブの配設する密度を変えることにより、別の部品を追加することなく便座内壁面の表面温度を均熱化することができる。 As described above, in the present embodiment, the side part of the toilet seat that is close to the toilet seat inner wall surface 14 from the radiation-type heating element and the rear of the toilet seat that is far from the radiation-type heating element to the toilet seat inner wall surface 14. By changing the density at which the grid-like ribs are arranged, the surface temperature of the inner wall surface of the toilet seat can be equalized without adding another part.

なお、本実施の形態においては、便座の側方部と後方部で格子状リブの配設密度を変えることにより、格子状リブの熱容量を変え、格子状リブでの輻射エネルギーの吸収量を変えることにより便座の表面温度の均一化を図ったが、格子状リブの配設密度を変えることに限らず、格子状リブの高さあるいは厚さを変えることにより格子状リブの熱容量を変えることにより同様の作用、降下を得ることができる。 In the present embodiment, the heat capacity of the grid ribs is changed by changing the arrangement density of the grid ribs at the side portion and the rear portion of the toilet seat, and the amount of radiation energy absorbed by the grid ribs is changed. The surface temperature of the toilet seat was made uniform by this, but not only by changing the density of the grid ribs, but also by changing the heat capacity of the grid ribs by changing the height or thickness of the grid ribs. The same effect and descent can be obtained.

また、本実施の形態においては、便座の側方部と後方部で格子状リブの配設密度を変えたが、これに限るものではなく、便座の形状により輻射型発熱体と便座内壁面との距離が異なる部分に対応して格子状リブの配設密度や格子状リブの高さや厚みを変えることにより、便座の表面温度の均一化を図ることができる。 Further, in the present embodiment, the arrangement density of the grid-like ribs is changed at the side portion and the rear portion of the toilet seat, but the present invention is not limited to this, and depending on the shape of the toilet seat, the radiation-type heating element and the toilet seat inner wall surface The surface temperature of the toilet seat can be made uniform by changing the arrangement density of the lattice-shaped ribs and the height and thickness of the lattice-shaped ribs corresponding to the portions having different distances.

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.
