Description

本考案は熱水供給システムで、特に給水配管の水流に対し予熱を行い、且つ水温を監視制御することができる熱水供給システムを指す。 The present invention is a hot water supply system, particularly a hot water supply system capable of preheating the water flow in the water supply pipe and monitoring and controlling the water temperature.

給湯器は主に、洗面や風呂に使用する温水の給湯に用い、すでに現在の家庭にとって不可欠の設備となっている。そしてよく見られる給湯器のタイプには、おおよそ、ガス給湯器、電気給湯器、太陽エネルギー給湯器等がある。その中で、ガス給湯器はその機能が安定し、設備コストとエネルギー源の費用が相対的に低価格であることから、現在広く一般家庭で採用されている。ガス給湯器は天然ガスの燃焼によって加熱され、そしてガスの燃焼が大量の酸素を消耗し、二酸化炭素を発生させる。ガスが不完全燃焼するとさらに一酸化炭素等の有毒ガスが発生するため、室内で使用すると、酸欠による窒息や一酸化炭素中毒の状況を起こしやすい。新聞やテレビニュースでこの種の事件の報道を時おり聞き、また、よく使用操作の不注意やガス配管の破裂がガス漏れを起こして、ガスが室内空間に充満し、使用のため点火した時や電気製品の火花が爆発や火災事故を起こす。特に冬季や雨季のシーズンには、人々がドアや窓をきっちり締め切り、室内外の空気が流通しない状況になるため、より前記の事故を起こしやすい。これからわかるように、ガス給湯器は、実は室内の使用に取り付けるのは不適合である。そして前記の事故発生を避けるため、通常、ガス給湯器を通風のよいベランダ、或いは屋外に取り付けて使用するため、給湯器と給湯蛇口間の距離が大幅に増加し、数メートルから十数メートル、ひどい場合は更に遠くなる。このように設置しての使用は、使用中、管の前後部分の給水温度に大きな差を生じ、供給される熱水が突然冷たくなったり、熱くなる現象が起きる以外に、特に給水を開始したばかりの段階では、さらに大量の水資源の浪費と使用上の不便を招く。例えば、熱水給水の初期の段階において、ユーザーが蛇口を開き、給湯器がガスを燃焼させ水を加熱し、適温の熱水が使用に提供されるまでに、通常、約１０秒から２０秒の待ち時間を経る必要がある。そのため使用上非常に不便であり、またこの期間、給水配管中の冷水がすべて排出され、これら流され使用されない水量は少なく見積もって、毎回５リットル以上で、各人毎年平均で少なくとも１,５００リットル以上の水量を浪費する。台湾地区の人口数の一年で計算すると、少なくとも３５０億リットルの水量を無駄にロスし、この結果、各人の水道代支出負担が増加するだけでなく、また大量の水資源を浪費する。前記の欠点は給湯ボイラーの取り付け、或いは大効率の電気給湯器を使用することで解決できる。ただ給湯ボイラー設備の設置費用が安価ではなく、実際、一般家庭の経済能力で負担できるものではない。そして、大効率の電気給湯器を取り付けると、必要な電気代が非常に高い以外に、更にその電気給湯器が必要とする大電流運転に適合させるため、電気供給設備を更新設置せねばならず極めて不便である。 Hot water heaters are mainly used to supply hot water for use in bathrooms and bathrooms, and are already indispensable for current homes. And the types of water heaters that are often seen include gas water heaters, electric water heaters, solar water heaters, and the like. Among them, gas water heaters are widely used in general households now because their functions are stable and equipment costs and energy source costs are relatively low. The gas water heater is heated by the combustion of natural gas, and the combustion of the gas consumes a large amount of oxygen and generates carbon dioxide. When the gas is incompletely burned, toxic gases such as carbon monoxide are further generated. Therefore, when the gas is used indoors, suffocation due to lack of oxygen and carbon monoxide poisoning are likely to occur. Occasionally heard news reports of this type of incident in newspapers and television news, and often when careless operation or rupture of gas piping caused gas leaks, gas filled the indoor space and ignited for use And sparks of electrical products cause explosions and fire accidents. Especially in the winter and rainy seasons, people close the doors and windows tightly and the air inside and outside does not circulate, so the accident is more likely to occur. As can be seen, the gas water heater is actually not suitable for indoor use. And in order to avoid the above-mentioned accident occurrence, usually the gas water heater is ventilated with good ventilation or used outdoors, so the distance between the water heater and the hot water faucet is greatly increased, from several meters to a dozen meters, In severe cases it will be further away. The use of such installations started particularly during the use, except that there was a big difference in the feed water temperature at the front and back of the pipe, and the supplied hot water suddenly cooled down or became hot At this stage, a large amount of water resources are wasted and inconvenience is caused. For example, in the early stages of hot water supply, the user typically opens the faucet, the water heater burns the gas and heats the water, and typically about 10 to 20 seconds before hot water is provided at the right temperature for use. It is necessary to go through the waiting time. Therefore, it is very inconvenient in use, and during this period, all the cold water in the water supply pipe is discharged, and the amount of water that is not used after flowing is estimated to be less than 5 liters each time, with an average of at least 1,500 liters per person per year. Waste the amount of water. If the number of people in the Taiwan area is calculated for one year, at least 35 billion liters of water is lost, which not only increases the burden of water costs for each person but also wastes a large amount of water resources. The above drawbacks can be solved by installing a hot water boiler or using a highly efficient electric water heater. However, the cost of installing hot water boiler facilities is not low, and in fact, it cannot be borne by the economic capacity of ordinary households. And if you install a high-efficiency electric water heater, you will need to update and install the electricity supply equipment to adapt to the high current operation that the electric water heater requires, in addition to the very high electricity bill Very inconvenient.

このことに鑑み、本考案は主に、節水でき、且つ使用に便利な熱水供給システムを提供し、それが利用する循環水配管の設計は給水配管内の水流を迅速に予設水温に到達させて供給使用し、ユーザーを待たせず、すばやく使用する目的を達成し、また周知の熱水システムが熱水を待つため、先に大量の冷水を流し、水資源を浪費する欠点を取り除くことができるものである。 In view of this, the present invention mainly provides a hot water supply system that can save water and is convenient to use, and the design of the circulating water pipe used by it quickly reaches the pre-established water temperature in the water supply pipe.

That is, the main control unit can monitor and control the water temperature in the water supply pipe by a water temperature measuring instrument attached in the pipe. This also adjusts the heating operation of the hot water source so that the output of the hot water source can ensure the supply and use of hot water that matches the set water temperature, thereby avoiding the disadvantage of water supply that suddenly gets cold or hot. You can remove it and avoid the danger of burns with hot water.

本考案はまた、安全に使用できる熱水供給システムを提供する。それは循環水配管の設計により、熱水源を遠距離の室外に配置したり、その他安全な所で運転させる。また温度が安定した熱水を迅速に室内での使用に供給し、このためガスを燃焼させる給湯器を使用しても酸欠や、毒ガスなどの危害が室内のユーザーに及ばない。 The present invention also provides a hot water supply system that can be used safely. It is designed by circulating water piping to place hot water sources outside a long distance outdoor or to operate in other safe places.

本考案は上記の部品で構成され、以下の三種の使用状況により、その技術的特徴、及び機能を更に進めて詳細に説明することができる。 The present invention is composed of the above-described parts, and the technical features and functions thereof can be further described in detail according to the following three types of usage conditions.

使用状況一、熱水供給の運転の臨時的起動：不特定の時間ポイント(つまり臨時的)に熱水を使用したい時、ユーザーはその使用側制御ユニット７の制御パネル７１の操作により、前記のメイン制御ユニットの温度制御部３１の運転を起動することができ、当該温度制御部３１の運転中、第一温度センサー５がその循環水配管２内の実際の水温が設定水温より低いことを検知すると、即そのポンプ４の運転を起動し、その循環配管中の冷水を駆動して冷水管１３内へ流入させる。そして、その冷水管１３には単一方向弁１６が設けられているため、その循環水配管２より冷水管１３内へ流した水は直接、再び給湯器中に送られ加熱される。同時にその循環水配管２はその給湯器の熱水出水口１４より新たな熱水を引き入れ、その循環水配管内の水流を迅速に設定水温に到達させ供給使用する。そしてその過程中、ユーザーはまたその使用側制御ユニット７の水温表示装置７２により、給水配管中の水温状態を観察し知ることができ、いつ熱水の使用を開始するか決定することができる。また、前記の給水予熱運転は、その循環水配管２内の水量が大量でないため、その循環水配管内の水流をすばやく設定水温に到達させることができ、ユーザーは待ち時間に多くを費やす必要がなく、すばやく正常な熱水の供給が得られる。このようにしてまた、周知の熱水システムが熱水を待つため、先に大量の冷水を流して水資源を浪費するという欠点を取り除くことができる。このほか、本考案の給湯器は周知のボイラー式給湯器とも異なる所があり、本考案では、平時に持続的に加熱保温をする必要がないため、大量のエネルギーコストが節約でき、且つ本考案の給湯器はまた周知のボイラー式給湯器の高温高圧がもたらす使用上の安全への配慮が不要である。 Use situation 1. Temporary activation of hot water supply operation: When the user wants to use hot water at an unspecified time point (that is, temporary), the user operates the control panel 71 of the use side control unit 7 to The operation of the temperature control unit 31 of the main control unit can be started, and during the operation of the temperature control unit 31, the first temperature sensor 5 detects that the actual water temperature in the circulating water pipe 2 is lower than the set water temperature. Then, the operation of the pump 4 is immediately started, and the cold water in the circulation pipe is driven to flow into the cold water pipe 13. And since the unidirectional valve 16 is provided in the cold water pipe | tube 13, the water which flowed into the cold water pipe | tube 13 from the circulating water pipe 2 is directly sent in a hot water heater again, and is heated. At the same time, the circulating water pipe 2 draws in hot water from the hot water outlet 14 of the water heater, and quickly uses the water flow in the circulating water pipe to reach the set water temperature. During the process, the user can also observe and know the water temperature state in the water supply pipe by the water temperature display device 72 of the use side control unit 7 and can determine when to start using the hot water. In addition, since the amount of water in the circulating water pipe 2 is not large in the water supply preheating operation, the water flow in the circulating water pipe can quickly reach the set water temperature, and the user needs to spend a lot of waiting time. No normal hot water supply can be obtained quickly. In this way, since the known hot water system waits for hot water, the disadvantage of wasting water resources by flowing a large amount of cold water first can be eliminated. In addition, the water heater of the present invention is different from the well-known boiler-type water heater, and in the present invention, since it is not necessary to continuously heat and keep warm during normal times, a large amount of energy cost can be saved and the present invention can be saved. The hot water heater of this type also does not require consideration for safety in use which is brought about by the high temperature and high pressure of the known boiler type water heater.

使用状況二、予約設定による熱水供給運転の起動：ユーザーがメイン制御ユニットの予約タイマー部３２により予約設定した時間になると、前記のメイン制御ユニットの温度制御部３１が即、自動的に一定時間運転を起動する。この温度制御部３１の運転期間に、第一温度センサー５がその循環水配管２内の実際の水温が設定水温より低いことを検知すると、即そのポンプ４の運転を起動し、その循環水配管中の低温水を駆動して冷水管１３内へ流入させ、更に給湯器中へ送り込んで加熱する。同時にその循環水配管２はその給湯器の熱水出水口１４より新たな熱水を引き入れ、その循環水配管内の水流を常に設定水温に保持させ、ユーザーはその予約運転期間に随時熱水を得ることができる。そして、その循環水配管２内の水量が大量でなく、且つその循環水配管の外部に設けた絶縁保温層が熱量の散失を減らすことができるため、本考案は前記の給水予熱期間に少額のエネルギーコストを支出するだけで、常にその循環水配管内の水温を使用に適した状態に保持することができる。 Usage status 2. Activation of hot water supply operation by reservation setting: When the time set by the user by the reservation timer unit 32 of the main control unit is reached, the temperature control unit 31 of the main control unit immediately and automatically Start driving. When the first temperature sensor 5 detects that the actual water temperature in the circulating water pipe 2 is lower than the set water temperature during the operation period of the temperature control unit 31, the operation of the pump 4 is started immediately, and the circulating water pipe is The low-temperature water inside is driven to flow into the cold water pipe 13 and further fed into the hot water heater to be heated. At the same time, the circulating water pipe 2 draws in fresh hot water from the hot water outlet 14 of the water heater, keeps the water flow in the circulating water pipe at the set water temperature, and the user draws hot water at any time during the reserved operation period. Obtainable. And since the amount of water in the circulating water pipe 2 is not large, and the insulating heat insulating layer provided outside the circulating water pipe can reduce the loss of heat, the present invention has a small amount during the water supply preheating period. By simply spending energy costs, the water temperature in the circulating water pipe can always be kept in a state suitable for use.

使用状況三、熱水供給の運転中に、恒温の熱水を維持して供給：その循環水配管２中の熱水が蛇口２３により持続的に流出し使用される時、その熱水源１はまた連続的にその給湯器の熱水出水口１４より熱水をその循環水配管中へ送る。そして、前記の熱水供給の運転と同時に、そのメイン制御ユニットの温度制御部３１がまた、その循環水配管２の前端に取り付けられた第二温度センサー６により、随時その流入する熱水温度を監視制御する。その給湯器の出水口１４より流入する熱水温度が設定水温を超えたことを検知すると、その温度制御部３１は即、その熱水源１を調整し、熱水への加熱を減らすことができる。反対に、流入する熱水の温度が設定水温より低いと、その熱水源１を調整し、熱水への加熱を増加し、その熱水源１が設定水温に適合した熱水をその循環水配管２中へ出力することが確保できる。これによりユーザーは恒温の熱水供給を得ることができ、急に冷たくなったり熱くなるという給水の欠点を取り除き、さらに高温の熱湯でやけどする危害を避けることができる。 Use situation 3, maintaining hot water at constant temperature during operation of hot water supply: When hot water in the circulating water pipe 2 is continuously discharged and used by the faucet 23, the hot water source 1 is Moreover, hot water is continuously sent into the circulating water piping from the hot water outlet 14 of the water heater. Simultaneously with the operation of supplying hot water, the temperature control unit 31 of the main control unit also adjusts the temperature of the flowing hot water as needed by the second temperature sensor 6 attached to the front end of the circulating water pipe 2. Monitor and control. When detecting that the temperature of the hot water flowing in from the outlet 14 of the water heater exceeds the set water temperature, the temperature control unit 31 can immediately adjust the hot water source 1 and reduce the heating to the hot water. . On the contrary, when the temperature of the flowing hot water is lower than the set water temperature, the hot water source 1 is adjusted to increase the heating to the hot water, and the hot water source 1 supplies hot water that matches the set water temperature to the circulating water piping. 2 can be secured. This allows the user to obtain a constant temperature hot water supply, removes the disadvantage of water supply that suddenly gets cold and gets hot, and avoids the danger of scalding with hot hot water.
