The heat of the warm air staying immediately below the ceiling plate 16 of the living room 14 is transmitted to the roofing material 22 using the existing ventilation structure to prevent snow accumulation. Since the flow of warm air from the vent 20 toward the ventilation building wrap 30 along the attic plate 24 under the roof material 22 is used, the roof material 22 near the eaves 32 is most warmed and effectively adheres to the roof. You can melt snow. In addition, a heat source for melting snow is not required. There is no need for complicated piping to conduct heat.

<Effect of Configuration 4>
Warm air passes between the roof material 22 and the attic plate 24 through the through holes 28 that penetrate the attic plate 24. The tile floor 26 and the attic plate 24 receive heat from the warm air flow and rise in temperature. The temperature of the roof material 22 is also increased by directly touching the warm air. Therefore, snow can be melted efficiently.

FIG.

以下、本考案の実施の形態を実施例毎に詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail for each example.

図１は実施例１の融雪装置１０を示す住宅の屋根の縦断面図である。図２はその外観図である。
この実施例の融雪装置１０は、居室１４の天井板１６の直下の暖気の流れを利用している。通常、冬の居室１４では、暖房による暖気が天井板１６の直下に集まる。通常、この部分が最も温度が高くなる。例えば天井板１６に循環扇１８を吊り下げておく。循環扇１８はこの暖気を居室１４の隅に押し流す役割を果たしている。居室１４の内部に自然対流が起きていれば、循環扇１８は無くても構わない。 FIG. 1 is a longitudinal sectional view of a house roof showing a snow melting device 10 according to a first embodiment. FIG. 2 is an external view thereof.
The snow melting device 10 of this embodiment uses the flow of warm air immediately below the ceiling plate 16 of the living room 14. Usually, in the living room 14 in the winter, warm air from heating gathers directly under the ceiling board 16. Usually, this part has the highest temperature. For example, the circulation fan 18 is suspended from the ceiling plate 16. The circulation fan 18 plays a role of pushing this warm air to the corner of the living room 14. If natural convection occurs inside the living room 14, the circulation fan 18 may be omitted.

気密性の良い近年の住宅には、換気のために、天井板１６の部屋の隅に近い部分に、天井板１６を貫通する通気口２０が設けられているものが多い。通気口２０から天井裏に抜けた空気は、屋根裏の最上部まで上昇し、換気棟包み３０を通じて外に排出されるように設計されている。既存の住宅で、通気口２０の無い場合には，後で図８で説明する要領で、通気口２０を新設するとよい。また、２階建て、３階建ての住宅であっても、換気のために、各階の天井板１６に上階に通じる通気口２０が設けられる。これらを利用するとよい。 Many recent houses with good airtightness have ventilation holes 20 penetrating the ceiling plate 16 at portions near the corners of the room of the ceiling plate 16 for ventilation. It is designed that the air that has escaped from the vent 20 to the ceiling rises up to the top of the attic and is discharged outside through the ventilation building wrap 30. If there is no vent hole 20 in an existing house, the vent hole 20 may be newly provided as described later with reference to FIG. Further, even in a two-story or three-story house, a vent hole 20 leading to the upper floor is provided on the ceiling plate 16 of each floor for ventilation. Use these.

ここで、本考案では、この通気口２０に近接した場所の屋根裏板２４に、屋根裏板２４を貫通する透孔２８を設けている。両者の位置関係は、後で図８を用いて説明する。通気口２０と透孔２８とは、いずれも、屋根材２２の最下部の軒先３２に接近した位置にのみ配置されている。既存の建物で、これ以外の位置に設けられた通気口２０は塞ぐとよい。通気口２０の無かった既存の住宅に通気口２０を新設する場合には、最上階の天井板１６の該当する位置に通気口２０を設けるとよい。一階に居間があり、最上階は寝室といった住宅でも、一階の居間から換気のための暖気が最上階まで上昇して、最上階の天井板１６の直下に集まる。これの暖気を利用する。 Here, in the present invention, a through hole 28 penetrating the attic plate 24 is provided in the attic plate 24 in the vicinity of the vent hole 20. The positional relationship between the two will be described later with reference to FIG. Both the vent hole 20 and the through hole 28 are arranged only at a position close to the eaves 32 at the bottom of the roof material 22. In an existing building, the vent 20 provided at a position other than this may be closed. When newly installing the vent 20 in an existing house that does not have the vent 20, the vent 20 may be provided at a corresponding position of the ceiling plate 16 on the top floor. There is a living room on the first floor, and even in a residence such as a bedroom on the top floor, warm air for ventilation rises from the living room on the first floor to the top floor and gathers directly under the ceiling board 16 on the top floor. Use the warmth of this.

図３と図４は、実施例１の融雪装置の詳細な縦断面図である。
図のように、通気口２０と透孔２８とは、通気口２０を通じて居室１４から天井板１６を突き抜けた暖気が、そのまま直線的に屋根材２２の裏面にまで達するような位置関係にあることが好ましい。暖気が他の経路を通らず、この経路に集中するように、通気口２０と透孔２８とを、屋根材２２の最下部の軒先３２に接近した位置にのみ配置した。なお、この実施例では屋根材２２が瓦である図を例示して説明をする。しかしながら、屋根材がスレートや金属板やプラスチック板等であっても、同様の効果がある。 3 and 4 are detailed longitudinal sectional views of the snow melting device of the first embodiment.
As shown in the figure, the vent hole 20 and the through hole 28 are in such a positional relationship that the warm air that has penetrated the ceiling plate 16 from the living room 14 through the vent hole 20 reaches the back surface of the roof material 22 as it is. Is preferred. The vent hole 20 and the through hole 28 are arranged only at a position close to the eaves 32 at the bottom of the roof material 22 so that the warm air does not pass through the other path but concentrates on this path. In this embodiment, a description will be given by exemplifying a diagram in which the roof material 22 is a tile. However, even if the roofing material is a slate, a metal plate, a plastic plate, or the like, the same effect is obtained.

以上の構造により、換気のために居室１４から通気口２０を抜けて排出される暖気は、透孔２８の直上の屋根材２２に衝突するように流れる。なお、この暖気の流れをさらに整えるために、例えば、通気口２０の近傍に、透孔２８以外への暖気の流れを塞ぐ案内板２１を設けるとよい。 With the above structure, the warm air discharged from the living room 14 through the vent hole 20 for ventilation flows so as to collide with the roof material 22 immediately above the through hole 28. In order to further regulate the flow of warm air, for example, a guide plate 21 that closes the flow of warm air to other than the through holes 28 may be provided in the vicinity of the vent 20.

このように、暖気の流れを形成すると、居室１４内の温度の高い暖気が軒先３２に近い屋根材２２を加熱する。さらに、透孔２８を通過した暖気は、屋根材２２と屋根裏板２４の間の隙間３３を通って、軒先３２から換気棟包み３０に向かう。そして、換気棟包み３０から外部に排出される。この隙間３３には屋根材２２を支える瓦敷２６が配置されている。瓦敷２６も暖気により加熱される。屋根裏板２４の、屋根材２２と対向する面も暖気により加熱される。 Thus, if the flow of warm air is formed, the warm air with high temperature in the living room 14 heats the roof material 22 close to the eaves 32. Further, the warm air that has passed through the through hole 28 passes through the gap 33 between the roofing material 22 and the attic plate 24, and then travels from the eaves edge 32 to the ventilation ridge wrap 30. And it is discharged | emitted from the ventilation wing package 30 outside. A tile floor 26 that supports the roof material 22 is disposed in the gap 33. The tile floor 26 is also heated by warm air. The surface of the attic plate 24 facing the roof material 22 is also heated by the warm air.

即ち、換気のために排出される暖気が、既存の通気口２０を通った後、屋根裏板２４に設けられた透孔２８に導かれることにより、屋根材２２とそれを支える構造物を加熱する。これにより、融雪効果を発揮する。この暖気はそのまま換気棟包み３０の方向に排出されるから、換気も妨げられない。また、降雪の有無にかかわらず、換気される暖気が常に隙間３３を流れるように設計されているので、降雪を検出して動作させる既存の融雪装置と比べて、降雪開始時の着雪を防ぐ効果が高い。また、既存の換気の流れを変えるだけで、融雪のための特別の熱源等を使用しないので、設備も簡単で済むという効果がある。 That is, after the warm air discharged for ventilation passes through the existing vent 20, it is guided to the through holes 28 provided in the roof back plate 24, thereby heating the roof material 22 and the structure supporting it. . Thereby, the snow melting effect is exhibited. Since this warm air is discharged as it is in the direction of the ventilation wing wrap 30, ventilation is not hindered. In addition, since it is designed so that warm air that is ventilated always flows through the gap 33 regardless of whether there is snowfall or not, it prevents snowfall at the start of snowfall compared to existing snow melting devices that detect and operate snowfall. High effect. In addition, there is an effect that the facility is simple because only a change in the existing ventilation flow is used and no special heat source for melting snow is used.

図５と図６とは、実施例２の融雪装置の詳細な縦断面図である。
この実施例では、天井板１６の通気口２０を通り抜けた暖気が、屋根裏板２４の下面に沿って上昇し換気棟包み３０に向かう。即ち、天井板１６を貫通する通気口２０を抜けた暖気は、屋根裏の最上部の換気棟包み３０に達してから外部に排出される。この暖気の流れにより屋根裏板２４が加熱される。 5 and 6 are detailed longitudinal sectional views of the snow melting device of the second embodiment.
In this embodiment, the warm air that has passed through the vents 20 of the ceiling board 16 rises along the lower surface of the attic board 24 and heads toward the ventilation building wrap 30. That is, the warm air that has passed through the vent hole 20 penetrating the ceiling board 16 reaches the uppermost ventilation wing wrap 30 in the attic and is then discharged to the outside. The attic plate 24 is heated by this warm air flow.

しかし、屋根裏板２４が断熱性が高いと、その熱が屋根材２２まで伝わらないことがある。そこで、屋根裏板２４の下面に沿って流れる暖気の熱を屋根材２２に伝える伝熱体３４が、瓦敷２６の直下に配置されている。伝熱体３４は、例えば、一端を屋根裏板２４の下面に露出させ、他端を瓦敷２６と連結した金属ボルトが適する。伝熱体３４は、屋根裏板２４の下面に沿って流れる暖気の熱を受けて温度上昇し、その熱を瓦敷２６に伝える。伝熱体３４は、屋根裏板２４に埋め込まれる金属板や金属棒である。屋根裏板２４に透孔を明けないので、屋根裏板２４に沿って軒先３２から換気棟包み３０に向かう暖気の流れを確保して、既存の換気機能を妨げないという効果がある。 However, if the attic plate 24 has high heat insulation, the heat may not be transferred to the roofing material 22. Therefore, a heat transfer body 34 that transmits the heat of warm air flowing along the lower surface of the attic plate 24 to the roofing material 22 is disposed directly below the tile floor 26. As the heat transfer body 34, for example, a metal bolt in which one end is exposed on the lower surface of the attic plate 24 and the other end is connected to the tile floor 26 is suitable. The heat transfer body 34 receives the heat of warm air flowing along the lower surface of the attic plate 24 and rises in temperature, and transmits the heat to the tile floor 26. The heat transfer body 34 is a metal plate or metal bar embedded in the attic plate 24. Since no through hole is made in the attic plate 24, there is an effect that the flow of warm air from the eaves 32 toward the ventilation building wrap 30 along the attic plate 24 is secured and the existing ventilation function is not hindered.

実施例１と実施例２とは、換気のための暖気の流れを利用している点で共通している。また、軒先３２に近い屋根材２２が最初に加熱されるように、通気口２０は、屋根材２２の最下部の軒先３２に接近した位置に配置されている。また、伝熱体３４から瓦敷２６を経て屋根材２２を加熱できるように、伝熱体３４は瓦敷２６と一体化していることが好ましい。瓦敷２６も金属製であれば、屋根材２２を加熱する効果が高まる。 Example 1 and Example 2 are common in that a warm air flow for ventilation is used. Further, the vent hole 20 is disposed at a position close to the eaves 32 at the bottom of the roof material 22 so that the roof material 22 near the eaves 32 is heated first. Moreover, it is preferable that the heat transfer body 34 is integrated with the roof tile 26 so that the roof material 22 can be heated from the heat transfer body 34 through the roof tile 26. If the tile floor 26 is also made of metal, the effect of heating the roof material 22 is enhanced.

図７は、実施例１と実施例２の構造をあわせて採用した融雪装置の縦断面図である。
図の天井板１６には、通気口２０が設けられている。また、屋根裏板２４には、透孔２８が設けられている。これは実施例１と同様の構造である。また、屋根裏板２４には、伝熱体３４が埋め込まれており、瓦敷２６と連結されている。これは実施例２と同様の構造である。即ち、この実施例では、屋根裏板２４の上面と下面を流れて換気される暖気の熱を屋根材２２に伝えて、融雪効果を得ている。従って、換気される暖気の熱を可能な限り屋根材２２側に伝えることができる。その他の効果は実施例１や２と変わらない。 FIG. 7 is a vertical cross-sectional view of a snow melting device that employs the structures of the first and second embodiments together.
The ventilation plate 20 is provided in the ceiling board 16 of the figure. The attic plate 24 is provided with a through hole 28. This is the same structure as in the first embodiment. In addition, a heat transfer body 34 is embedded in the attic plate 24 and is connected to the tile floor 26. This is the same structure as in the second embodiment. That is, in this embodiment, the heat of the warm air that flows through the upper and lower surfaces of the attic plate 24 and is ventilated is transmitted to the roof material 22 to obtain a snow melting effect. Therefore, the heat of the warm air ventilated can be transmitted to the roof material 22 side as much as possible. Other effects are the same as those of the first and second embodiments.

居室１４で居住者が生活しているときは常に天井板１６の直下の暖気が換気されるので、屋根材２２が加熱されて融雪効果を発揮する。しかしながら、居住者が不在のときは暖気が不足し、積雪を阻止できない。そこで、この実施例では、屋根材２２と天井板１６の間の隙間３３に温度センサ３８を取付けた。図の例では、透孔２８の近傍に温度センサ３８を配置し、瓦敷２６または屋根裏板２４の温度を検出する。一方、居室１４側には、空調機３６を設ける。これは、既存のエアコンでよい。温度センサ３８は、居室１４を暖める空調機３６に対して、検出温度が基準値（例えば、摂氏５度）以下のときに暖房運転をするようにオンオフ制御する制御信号を出力する。不在のときは、この制御により、自動的に天井板１６の直下に暖気の流れを作るとよい。 When the resident lives in the living room 14, the warm air immediately below the ceiling board 16 is always ventilated, so that the roofing material 22 is heated and exhibits a snow melting effect. However, when there is no resident, there is insufficient warm air and snow cannot be prevented. Therefore, in this embodiment, the temperature sensor 38 is attached to the gap 33 between the roof material 22 and the ceiling board 16. In the illustrated example, a temperature sensor 38 is disposed in the vicinity of the through hole 28 to detect the temperature of the tile floor 26 or the attic board 24. On the other hand, an air conditioner 36 is provided on the living room 14 side. This can be an existing air conditioner. The temperature sensor 38 outputs, to the air conditioner 36 that warms the living room 14, a control signal that performs on / off control so that the heating operation is performed when the detected temperature is equal to or lower than a reference value (for example, 5 degrees Celsius). In the absence, it is preferable to automatically create a warm air flow directly under the ceiling board 16 by this control.

図８は天井板１６と２４の平面図である。
図８の（ａ）は天井板１６を居室１４側から見た平面図である。図のように、複数の通気口２０が天井板１６の隅に近い部分に配置されている。これらの通気口２０はいずれも、屋根材２２の最下部の軒先３２に接近した位置のみに直線的に配列されている。一方、図８の（ｂ）は屋根裏板２４を天井板１６側から見た平面図である。図のように、伝熱体３４は、通気口２０の直上に位置するように設けられている。また、伝熱体３４は通気口２０と同様に、屋根材２２の最下部の軒先３２に接近した位置のみに直線的に配列されている。伝熱体３４は図のように、瓦敷２６を屋根裏板２４に固定しかつ電熱の役割を果たすために、列状に設けられている。これで、十分な熱を屋根材２２側に伝達できる。 FIG. 8 is a plan view of the ceiling plates 16 and 24.
(A) of FIG. 8 is the top view which looked at the ceiling board 16 from the room 14 side. As shown in the figure, a plurality of vent holes 20 are arranged in a portion near the corner of the ceiling board 16. All of these vents 20 are linearly arranged only at positions close to the lowermost eaves 32 of the roofing material 22. On the other hand, FIG. 8B is a plan view of the attic plate 24 viewed from the ceiling plate 16 side.
