Abstract

<P>PROBLEM TO BE SOLVED: To provide a snow-melting system which suppresses the running cost of a heater portion. <P>SOLUTION: In this snow-melting system, water in a water storage tank 2, which is warmed by the heater portion 14, is warmed by exhaust heat from a submerged pump 15 which is operated for melting snow. Thus, during the melting of the snow, the exhaust heat from the submerged pump 15, that is, heat generated from a motor portion and a pump portion serves as a heat source, so as to restrain the temperature of the water in the water storage tank 2 from decreasing due to the inflow of snow water. This reduces a burden on the heater portion 14. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、屋根の雪を融かす融雪装置に関する。   The present invention relates to a snow melting device for melting snow on a roof.

豪雪地域では、建屋を積雪から守るために、屋根の雪を融かすことが行なわれている。   In heavy snowfall areas, the snow on the roof is melted to protect the building from snow.

こうした融雪に用いられる融雪装置には、特許文献１に示されるように屋根上を流れ落ちる雨水を貯水槽で集水しておき、融雪時、陸上ポンプの運転により、貯水槽内の水を屋根の上部へ散水させて、屋根上の雪を融かす循環式の装置がある。   In such a snow melting device used for melting snow, rain water that flows down on the roof is collected in a water storage tank as shown in Patent Document 1, and when the snow melts, water in the water storage tank is drained by the operation of a land pump. There is a circulating device that sprinkles water on the top and melts snow on the roof.

ところで、融雪するために、貯水槽内の水は、電熱線などで構成されるヒーター部を用いて、融雪に適した所定温度まで加温して、一定に保つことが行なわれる。
特開２００５−８３１８０号公報 By the way, in order to melt snow, the water in the water storage tank is heated to a predetermined temperature suitable for melting snow and kept constant by using a heater unit composed of a heating wire or the like.
JP 2005-83180 A

ところで、融雪時は、屋根から雨水だけでなく雪融け水も貯水槽で集水される。このため、融雪が始まると、雪融け水の貯水により、貯水槽内の水温が次第に低下していく挙動が見られる。   By the way, at the time of melting snow, not only rain water but also snow melting water is collected in the water storage tank. For this reason, when snow melting begins, the water temperature in the water tank gradually decreases due to the storage of the melted snow.

ところが、貯水槽内の水温が低下すると、融雪効率が低下する。そこで、通常、融雪時には、ヒーター部を用いて、雪融け水による温度低下を抑えることが行なわれる。このため、融雪装置は、ヒーター部の稼動により、かなりランニングコストが要求される傾向があり、経済的な負担となっている。   However, when the water temperature in the water storage tank decreases, the snow melting efficiency decreases. Therefore, normally, during snow melting, a heater unit is used to suppress a temperature drop due to snow melting water. For this reason, the snow melting apparatus tends to require a considerable running cost due to the operation of the heater section, and is an economical burden.

そこで、本発明の目的は、ヒーター部のランニングコストが抑えられる融雪装置を提供することにある。   Therefore, an object of the present invention is to provide a snow melting device that can reduce the running cost of the heater section.

請求項１に係る発明は、上記目的を達成するために、貯水槽内の水を水中ポンプで屋根へ揚水する構成を採用して、水中ポンプの運転時に生ずる排熱で貯水槽内の水を加温可能にした。   In order to achieve the above object, the invention according to claim 1 employs a configuration in which water in the water storage tank is pumped to the roof by a submersible pump, and the water in the water storage tank is removed by exhaust heat generated during operation of the submersible pump. Heating was possible.

同構成により、融雪時は、ポンプ運転時の水中ポンプからの排熱、すなわちモータ部やポンプ部から発生する熱が熱源となって、雪融け水の流入で貯水槽内の水温が低下するのを抑える。   With this configuration, during snow melting, the heat exhausted from the submersible pump during pump operation, that is, the heat generated from the motor unit and pump unit, becomes the heat source, and the water temperature in the water storage tank decreases due to the inflow of snow melting water. Suppress.

請求項２に係る発明は、さらに、貯水槽に、地下水の補給を可能とした水補給手段が設けることによって、雨水の不足に対処するだけでなく、さらには温かい地下水の利用により、貯水槽内の水温が低下するのを抑える。   The invention according to claim 2 further provides a water replenishment means that enables replenishment of groundwater to the water storage tank, thereby not only dealing with a shortage of rainwater but also by using warm groundwater. To prevent the water temperature from dropping.

請求項３に係る発明は、さらに、貯水槽の周囲を断熱部により断熱することによって、貯水槽内の水温が低下するのを抑える。   The invention according to claim 3 further suppresses a decrease in the water temperature in the water tank by insulating the periphery of the water tank with a heat insulating portion.

請求項１に係る発明によれば、融雪時、水中ポンプからの排熱で、融雪水により貯水槽内の水温が低下するのが抑えられる。   According to the invention which concerns on Claim 1, it is suppressed that the water temperature in a water storage tank falls by snowmelt water by the waste heat from a submersible pump at the time of snow melting.

それ故、雪融け水の影響で低下する水温を上昇させるのに費やすヒーター部のランニングコスト（例えば電気代）は軽減でき、経済的な負担が低減できる。   Therefore, the running cost (for example, electricity bill) of the heater unit spent for raising the water temperature that is lowered due to the melted snow can be reduced, and the economic burden can be reduced.

請求項２に係る発明によれば、貯水槽が水で満たされなくなる状況を防ぐことができる。しかも、地下水が補給されたときは、温かい地下水が利用される分、ヒーター部のランニングコストの軽減ができる。   According to the invention which concerns on Claim 2, the condition where a water tank is no longer filled with water can be prevented. Moreover, when groundwater is replenished, the running cost of the heater can be reduced by the amount of warm groundwater used.

請求項３に係る発明によれば、断熱部により、貯水槽から外部へ逃げる熱が抑えられるから、効果的に貯水槽内の水温を上昇させることができ、ヒーター部のランニングコストの軽減に寄与する。   According to the invention which concerns on Claim 3, since the heat which escapes from a water storage tank to the exterior is suppressed by the heat insulation part, the water temperature in a water storage tank can be raised effectively, and it contributes to reduction of the running cost of a heater part. To do.

以下、本発明を図１に示す第１の実施形態にもとづいて説明する。   The present invention will be described below based on the first embodiment shown in FIG.

図１は融雪装置の概略構成図を示し、図中１は建屋、２は例えば建屋１と隣接して地上に設置された、周囲が全て壁で囲まれてなる貯水槽、３は貯水槽２の周囲を断熱するために貯水槽２の外面に設けられた断熱部材（本願の断熱部に相当）、４は例えば貯水槽２に隣接して設置された降雪センサー（降雪を検知するセンサー）である。   FIG. 1 shows a schematic configuration diagram of a snow melting device, in which 1 is a building, 2 is a water tank installed on the ground adjacent to the building 1, for example, and surrounded by walls, 3 is a water tank 2 A heat insulating member (corresponding to the heat insulating portion of the present application) provided on the outer surface of the water storage tank 2 to insulate the periphery of the water storage tank 4 is a snowfall sensor (sensor for detecting snowfall) installed adjacent to the water storage tank 2, for example. is there.

貯水槽２には、例えば井戸揚水ポンプの吐出部（いずれも図示しない）から延びる地下水用補給配管６（本願の水補給手段に相当）や、水道水配水管（図示しない）から延びる市水用補給配管７が接続されている。これら補給配管６，７の出口部には、低水位用のボールタップ８が接続されている。このボールタップ８により、貯水槽２は、貯水量が不足することがないよう、所定の低水位までは、選択した地下水や市水（水道水）が補給される構造にしてある。補給は、地下水、市水（水道水）のどちらか一方で行なわれる。なお、地下水用補給配管６には、地下水から屋根の変色をきたす成分、例えば鉄、マンガンなどを除去する除鉄・除マンガン用のろ過器９が設置してある。   The water storage tank 2 has, for example, a groundwater supply pipe 6 (corresponding to the water supply means of the present application) extending from a discharge part (not shown) of a well pump, or a city water supply extending from a tap water distribution pipe (not shown). A supply pipe 7 is connected. A ball tap 8 for low water level is connected to the outlets of the supply pipes 6 and 7. With this ball tap 8, the water tank 2 is structured such that the selected ground water or city water (tap water) is replenished up to a predetermined low water level so that the amount of water stored is not insufficient. Replenishment is carried out using either groundwater or city water (tap water). In addition, the groundwater supply pipe 6 is provided with a filter 9 for removing iron and removing manganese that removes components that cause discoloration of the roof from the groundwater, such as iron and manganese.

貯水槽２には、集合管１１を介して、建屋１の屋根１ａの最下部に据え付けてある雨樋１ｂ，１ｂから下がる縦配管１０ａ，１０ｂが接続されている。この配管構造により、屋根１ａから流れ落ちる雨水が、貯水槽２で集水されて貯溜されるようにしている。なお、雨水に含まれるごみ（葉っぱなどの異物）を取り除くフィルター１２や逆流を防ぐ逆止弁１３が設けてある。   Longitudinal pipes 10 a and 10 b descending from rain gutters 1 b and 1 b installed at the bottom of the roof 1 a of the building 1 are connected to the water storage tank 2 through a collecting pipe 11. With this piping structure, rainwater flowing down from the roof 1a is collected in the water storage tank 2 and stored. A filter 12 that removes dust (foreign matter such as leaves) contained in rainwater and a check valve 13 that prevents backflow are provided.

貯水槽２内の底部には、防水式の電熱ヒーター１４（本願のヒーター部に相当）が設置されている。この電熱ヒーター１４により、貯水槽２内の水を融雪に適する所定の温度まで加温できる構造にしている。また貯水槽２の内部、例えば底部には、水中ポンプ１５（例えば水中電動モータ１６に多段のポンプ部１７を直結して構成されるもの）が据え付けられている。水中ポンプ１５は、水中電動モータ１６、ポンプ部１７のいずれもが、常時、貯水槽２内の水と接触（浸漬）するように据え付けられていて、ポンプ運転時に生じる水中電動モータ１６やポンプ部１７からの熱（排熱）が、そのまま周りの水へ伝わるようにしている。この水中ポンプ１５の吐出部１５ａは、吐出配管１８を介して、例えば貯水槽２の上部に設置された自動運転ユニット部２０に接続されている。自動運転ユニット２０は、例えばケーシング２１の内部に、入口と出口をもちかつ圧力センサーや流量センサー（いずれも図示しない）が組み込まれた通管部２２と、制御部２３（本願の制御手段に相当）が収められる。吐出配管１８は、そのうちの通管部２２の入口に接続してある。また通管部２２の出口は、揚水配管２４を介して、屋根１ａの上部、例えば最上部に据え付けてある散水管２５に接続されている。散水管２５は、例えば屋根１ａの稜線に沿って延び、両側にはそれぞれ散水孔（図示しない）が形成されている。これにより、水中ポンプ１５によって揚水された水が、散水管２５から屋根上面へ散水される構造にしている。   A waterproof electric heater 14 (corresponding to the heater portion of the present application) is installed at the bottom of the water tank 2. With this electric heater 14, the water in the water storage tank 2 can be heated to a predetermined temperature suitable for melting snow. Further, a submersible pump 15 (for example, one configured by directly connecting a multistage pump unit 17 to the submersible electric motor 16) is installed in the water tank 2, for example, at the bottom. The submersible pump 15 is installed so that both the submersible electric motor 16 and the pump section 17 are always in contact with (immersed in) the water in the water storage tank 2, and the submersible electric motor 16 and the pump section that are generated during pump operation. Heat (waste heat) from 17 is transmitted to surrounding water as it is. The discharge unit 15 a of the submersible pump 15 is connected to an automatic operation unit unit 20 installed, for example, at the upper part of the water storage tank 2 through a discharge pipe 18. The automatic operation unit 20 includes, for example, a pipe 22 having an inlet and an outlet and a pressure sensor and a flow rate sensor (both not shown) and a controller 23 (corresponding to the control means of the present application) inside the casing 21. ) Is stored. The discharge pipe 18 is connected to the inlet of the through pipe portion 22 among them. The outlet of the pipe 22 is connected via a pumping pipe 24 to a sprinkler 25 installed on the top of the roof 1a, for example, the top. The water spray pipe 25 extends along, for example, a ridge line of the roof 1a, and water spray holes (not shown) are formed on both sides. Thus, the water pumped up by the submersible pump 15 is sprayed from the water spray pipe 25 to the roof top surface.

また制御部２３は、例えばマイクロコンピュータから構成される。この制御部２３に、電熱ヒーター１４や降雪センサー４や貯水槽２内の水温を検知する水温センサー２ａ（例えば貯水槽２内に設置）や水中ポンプ１５の水中電動モータ１７や圧力センサーや流量センサーが接続してある。制御部２３には、例えば、冬季時期を検出するタイマー、該冬季時に貯水槽２内の水を所定温度（融雪可能な温度）に保つよう電熱ヒーター１４をオンオフ制御する機能、降雪センサー４で降雪を検知すると目標の圧力かつ一定の流量で貯水を吐出させるよう水中ポンプ１５を運転させる機能などが設定されている。これにより、冬季時、貯水槽２内の水は、融雪可能な状態で保温されて待機する。また降雪を感知すると、水中ポンプ１５で、貯水槽２内の水を屋根１ａへ散水するという、循環運転が行なわれるようにしてある。   Moreover, the control part 23 is comprised, for example from a microcomputer. The controller 23 includes an electric heater 14, a snowfall sensor 4, a water temperature sensor 2a for detecting the water temperature in the water tank 2 (for example, installed in the water tank 2), a submersible electric motor 17 of the submersible pump 15, a pressure sensor, and a flow sensor. Is connected. The controller 23 includes, for example, a timer for detecting the winter season, a function for controlling the on / off of the electric heater 14 so as to keep the water in the water tank 2 at a predetermined temperature (temperature capable of melting snow) during the winter season, A function for operating the submersible pump 15 to discharge the stored water at a target pressure and a constant flow rate is set. Thereby, at the time of winter, the water in the water tank 2 is kept warm in a state where snow melting is possible. When snowfall is detected, a circulating operation is performed in which the water in the water storage tank 2 is sprinkled onto the roof 1a by the submersible pump 15.

なお、揚水配管２４の上流側と、集合管１１の下流側（逆止弁１３の一次側）との間は、切換弁２６をもつ短絡配管２７（バイパス管）でバイパス接続されている。同構造により、切換弁２６を貯水が水中ポンプ１５と貯水槽２間を循環するよう切り換えると、短絡経路２７を通る短絡経路により、水中ポンプ１５の運転だけでも、水中ポンプ１５の排熱で加温（水温上昇）が行なわれる構造にしてある。   The upstream side of the pumping pipe 24 and the downstream side of the collecting pipe 11 (primary side of the check valve 13) are bypass-connected by a short-circuit pipe 27 (bypass pipe) having a switching valve 26. With the same structure, when the switching valve 26 is switched so that the water is circulated between the submersible pump 15 and the water tank 2, the submersible pump 15 is heated by the exhaust heat of the submersible pump 15 only by the short circuit path passing through the short circuit path 27. The structure is such that the temperature (water temperature rise) is performed.

つぎに、このように構成された融雪装置の作用について説明する。   Next, the operation of the snow melting device thus configured will be described.

貯水槽２内に雨水が貯水されているとする。この貯水量は、最低水位レベルまでが地下水で、上側の水位までが、屋根１ａから雨樋１ｂを伝わって流れ落ちる雨水が占める。なお、貯水量を超える雨水は、図示はしないが貯水槽２に付いているオーバーフロー管を通じて、外部へ導出される。   Assume that rainwater is stored in the water tank 2. The amount of stored water is groundwater up to the lowest water level, and rainwater flowing down from the roof 1a through the gutter 1b occupies the upper water level. Note that rainwater exceeding the amount of stored water is led out to the outside through an overflow pipe attached to the water storage tank 2 (not shown).

電熱ヒーター１４は、制御部２３のタイマー機能により、冬季時、作動する。この作動により、貯水槽２内の水は加温される。そして、制御部２３で行なわれる電熱ヒーター１４の通電制御（オンオフ制御）により、貯水槽２内の水は、融雪に適した水温に一定に保たれ続ける。ここで、貯水槽２は、断熱部材３で断熱されているから、このときの水温を一定の温度に保つときに求められる加温エネルギーは最小ですむ。   The electric heater 14 is operated in winter by the timer function of the control unit 23. By this operation, the water in the water storage tank 2 is heated. And by the energization control (on / off control) of the electric heater 14 performed by the control unit 23, the water in the water storage tank 2 is kept constant at a water temperature suitable for melting snow. Here, since the water tank 2 is insulated by the heat insulating member 3, the heating energy required when the water temperature at this time is kept at a constant temperature is minimized.

今、例えば降雪が始まり、この降雪が降雪センサー４で感知されたとする。すると、制御部２３は、水中ポンプ１５を稼動させる。つまり、水中電動モータ１７が励磁され、ポンプ部１７が駆動される。   Now, for example, it is assumed that snowfall has started and this snowfall is detected by the snowfall sensor 4. Then, the control unit 23 operates the submersible pump 15. That is, the underwater electric motor 17 is excited and the pump unit 17 is driven.

すると、水中ポンプ１５により、貯水槽２内の水（雨水）は、吐出配管１８、通管部２２、揚水配管２４を経て、屋根１ａの最上部に有る散水管２５へ送水される。これにより、貯水は、散水管２５の両側の各散水孔（図示しない）から屋根１ａへ散水される。既に屋根１ａの積もっていた雪は、この散水により融ける。また散水により、屋根１ａへは雪が積もりにくくなる。   Then, the water (rain water) in the water storage tank 2 is sent by the submersible pump 15 to the sprinkler pipe 25 at the top of the roof 1a through the discharge pipe 18, the communication pipe section 22, and the pumping pipe 24. Thereby, water storage is sprinkled from the water spray holes (not shown) on both sides of the water spray pipe 25 to the roof 1a. The snow already on the roof 1a is melted by this watering. Moreover, it becomes difficult for snow to accumulate on the roof 1a by watering.

散水された雨水は、雪融け水と一緒に、屋根１ａの上面を伝わり、雨樋１ｂ、１ｂを経て、縦配管１０ａ，１０ｂから流れ落ちる。さらに同水は、集合管１１を通り、フィルター１２、逆止弁１３を経て、貯水槽２内へ戻る。つまり、雨水は、貯水槽２と屋根１ａとの間を循環しながら流れて、屋根１ａ上を融雪する（屋根融雪）。なお、地下水の鉄分やマグネシウム分は、ろ過器９で取り除かれているので、地下水が屋根１ａに散水されても、屋根１ａは変色することはない。   The sprinkled rainwater travels along the top surface of the roof 1a together with the melted snow and flows down from the vertical pipes 10a and 10b through the rain gutters 1b and 1b. Further, the water passes through the collecting pipe 11, returns to the water tank 2 through the filter 12 and the check valve 13. That is, rainwater flows while circulating between the water storage tank 2 and the roof 1a, and melts snow on the roof 1a (roof snow melting). In addition, since the iron content and magnesium content of groundwater are removed with the filter 9, even if groundwater is sprayed on the roof 1a, the roof 1a does not discolor.

このとき、雨水だけでなく雪融け水も貯水槽２へ集水されるため、融雪が始まると、貯水槽２内の水温は次第に低下していく。   At this time, not only rainwater but also melted snow is collected in the water storage tank 2, so that when the snow melting starts, the water temperature in the water storage tank 2 gradually decreases.

この水温は、電熱ヒーター１４の作動により、再び所定の温度まで加温されるが、このとき電熱ヒーター１４にだけに依存すると、加温負荷が大きいため、かなり電熱ヒーター１４を稼動させることになり、電熱ヒーター１４の雪融け水の低下する水温を上昇させるのに費やすランニングコストはかなりのものとなる。   This water temperature is heated again to a predetermined temperature by the operation of the electric heater 14, but depending on only the electric heater 14 at this time, since the heating load is large, the electric heater 14 is considerably operated. In addition, the running cost spent for raising the temperature of the electric heater 14 at which the snow melting water decreases is considerable.

ここで、融雪に用いられるポンプは、貯水槽２内の水と接触する状態で設置された水中ポンプ１５であるので、ポンプ運転中、水中ポンプ１５の排熱、すなわち水中電動モータ１６やポンプ部１７から発生する熱は、貯水槽２内の水（雨水）に伝わる（放熱）。これにより、貯水槽２内の水（雨水）は、水中ポンプ１５の運転に伴い発生する熱により加温される。つまり、水中ポンプ１５の排熱により、雪融け水の流入で貯水槽２内の水温が低下するのが抑制される。   Here, since the pump used for snow melting is the submersible pump 15 installed in contact with the water in the water storage tank 2, the exhaust heat of the submersible pump 15 during the pump operation, that is, the submersible electric motor 16 and the pump unit. The heat generated from 17 is transmitted to the water (rain water) in the water tank 2 (heat radiation). Thereby, the water (rain water) in the water tank 2 is heated by the heat generated by the operation of the submersible pump 15. That is, due to the exhaust heat of the submersible pump 15, the water temperature in the water storage tank 2 is prevented from being lowered due to the inflow of melted snow.

これで、電熱ヒーター１４の負荷は抑えられる。この結果、電熱ヒーター１４の雪融け水の低下する水温を上昇させるのに費やすランニングコスト（例えば電気代）は削減でき、融雪装置を稼動させるのに求められる経済的な負担を小さくすることができる。特に貯水槽２の周囲を断熱部材３で断熱したことで、貯水槽２から外部へ逃げる熱が抑えられるから、効果的に貯水槽２内の水温を上昇させることができ、電熱ヒーター１４のランニングコストの軽減に貢献する。   Thereby, the load of the electric heater 14 is suppressed. As a result, it is possible to reduce the running cost (for example, electricity bill) spent for raising the temperature of the electric heater 14 that melts the snow melt, and the economic burden required to operate the snow melter can be reduced. . In particular, the heat insulation member 3 insulates the periphery of the water tank 2 so that the heat escaping from the water tank 2 to the outside can be suppressed, so that the water temperature in the water tank 2 can be effectively increased and the electric heater 14 can be run. Contributes to cost reduction.

しかも、貯水槽２内へ地下水を補給する構造にすると、貯水槽２の水量が不足する状況を防ぐことができるだけでなく、温かい地下水が利用される分、電熱ヒーター１４の作動（通電時間：小）が少なくてすみ、一層、電熱ヒーター１４のランニングコストの削減ができる。   Moreover, the structure in which groundwater is supplied into the water storage tank 2 not only prevents the situation where the amount of water in the water storage tank 2 is insufficient, but also activates the electric heater 14 for the amount of warm groundwater used. ) And the running cost of the electric heater 14 can be further reduced.

また短絡配管２７で貯水槽２と水中ポンプ１５間を短絡させた構造すると、たとえ電熱ヒーター１４が使用できない状況になったとしても、水中ポンプ１５の排熱を利用して、短絡配管２７を経由する循環経路で、貯水槽２内の水の加温が行なえる利点もある。   In addition, if the storage tank 2 and the submersible pump 15 are short-circuited by the short-circuit pipe 27, even if the electric heater 14 cannot be used, the waste heat of the submersible pump 15 is used to pass through the short-circuit pipe 27. There is also an advantage that the water in the water storage tank 2 can be heated by the circulation path.

また本発明は、図２〜図５に示す第２〜第５の実施形態のようにしてもよい。   Moreover, you may make this invention like the 2nd-5th embodiment shown in FIGS.

図２に示す第２の実施形態は、貯水槽２を地面に埋設して、地面を断熱部として用いて貯水槽２の周囲を断熱したものである。   2nd Embodiment shown in FIG. 2 embeds the water tank 2 in the ground, and heat-insulated the circumference | surroundings of the water tank 2 using the ground as a heat insulation part.

図３に示す第３の実施形態は、貯水槽２内の水を建屋１の中水道として利用できるようにしたものである。具体的には、図３は、揚水配管２４の途中に切開弁３０を介し、水洗トイレ３１の流入配管３２を接続して、貯水槽２内の雨水をトイレ水として利用できるようにしたものである。むろん、水洗トイレ３１に限らず、散水栓に接続して、貯水槽２内の雨水を散水や洗車水として用いても構わない。   In the third embodiment shown in FIG. 3, the water in the water tank 2 can be used as the middle water in the building 1. Specifically, FIG. 3 shows that the inflow pipe 32 of the flush toilet 31 is connected to the pumping pipe 24 through the incision valve 30 so that rainwater in the water storage tank 2 can be used as toilet water. is there. Of course, it is not limited to the flush toilet 31, and the rain water in the water storage tank 2 may be used as water spray or car wash water by connecting to a water sprinkler.

図４に示す第４の実施形態は、制御部２３に、アンテナ３５や、アンテナ３５から入力される通信信号により水中ポンプ１５が稼動する機能を設けて、携帯電話やパソコン通信から入力される、気象情報に基づく運転開始指令にしたがい、遠隔操作により、降雪直前からも融雪運転が行なわれるようにしたものである。   In the fourth embodiment shown in FIG. 4, the control unit 23 is provided with a function for operating the submersible pump 15 by a communication signal input from the antenna 35 or the antenna 35, and is input from a mobile phone or personal computer communication. According to the operation start command based on weather information, the snow melting operation is performed even immediately before snowfall by remote control.

図５に示す第５の実施形態は、融雪装置を夏季時の散水として利用できるようにしたものである。具体的には、夏季を感知するためのセンサーとして照度を検知する照度センサー３７を設置して、強い日射量となる夏季時に、水中ポンプ１５を稼動させて、屋根１ａに貯水槽２内の水を散水させ、建屋１の冷却が行なえるようにしたものである。   In the fifth embodiment shown in FIG. 5, the snow melting device can be used as watering in summer.
