Description

本発明は、沸き上げ方法を変更する給湯装置に関するものである。   The present invention relates to a hot water supply apparatus that changes a boiling method.

従来、この種の給湯装置は、例えば、図10のようなものがある(例えば、特許文献1参照)。   Conventionally, this kind of hot water supply apparatus has a thing like FIG. 10, for example (for example, refer patent document 1).

図10は、特許文献1に記載された従来の給湯装置を示すものである。   FIG. 10 shows a conventional hot water supply apparatus described in Patent Document 1. As shown in FIG.

図10に示すように、貯湯槽1と、この貯湯槽1の湯水を加熱する加熱手段2と、加熱手段2を制御する沸き上げ制御手段3と、沸き上げ制御手段3の制御方法を設定するリモコン4を備える。   As shown in FIG. 10, the hot water storage tank 1, the heating means 2 for heating the hot water in the hot water tank 1, the boiling control means 3 for controlling the heating means 2, and the control method for the boiling control means 3 are set. A remote control 4 is provided.

貯湯槽1の湯水は貯湯槽1の底部から沸き上げ配管11を通じて加熱手段2へ通水され、高温に沸き上げられた後に貯湯槽1の上部へ再び貯湯される。高温に沸き上げられた貯湯槽1内の湯水は、給湯栓13が開栓されると混合弁14によって給水配管からの給水と所定温度に混合されて給湯され、高温水が取り出されることによって貯湯槽1内で不足する湯水は、貯湯槽1の底部に給水配管から給水が供給され、貯湯槽1内は常に湯水で満たされる仕組みとなっている。   Hot water in the hot water tank 1 is passed from the bottom of the hot water tank 1 through the heating pipe 11 to the heating means 2, heated to a high temperature, and then stored again in the upper part of the hot water tank 1. When the hot water tap 13 is opened, the hot water in the hot water tank 1 boiled at a high temperature is mixed with the water supplied from the water supply pipe by the mixing valve 14 at a predetermined temperature, and hot water is taken out. Hot water that is deficient in the tank 1 is supplied from the water supply pipe to the bottom of the hot water tank 1 so that the hot water tank 1 is always filled with hot water.

貯湯槽1全体の沸き上げは主に電力需要の少ない夜間に行われ、夜間沸き上げた湯量では不足する場合に昼間に沸き上げが行われる。   The entire hot water tank 1 is heated mainly at night when the demand for electric power is low, and is heated during the day when the amount of hot water heated at night is insufficient.

これら沸き上げの制御は、沸き上げ制御手段3が行い、沸き上げ制御手段3は、複数の運転モードを持つ。各運転モードは、使用湯量に応じて貯湯槽1内の最低湯量を確保するように沸き上げを行う。   The boiling control is performed by the boiling control means 3, and the boiling control means 3 has a plurality of operation modes. In each operation mode, boiling is performed so as to secure the minimum amount of hot water in the hot water tank 1 according to the amount of hot water used.

たとえば、満タンモードは、常時湯切れのないように大容量の貯湯量を確保させたいモードであり、おまかせモードは過去の使用実績に応じて夜間と昼間に沸き上げる湯量を最適に保つ。使用湯量の少ない使用者にとっては夜間のみの沸き上げを行う運転モードが適している。   For example, the full tank mode is a mode in which a large-capacity hot water storage amount is to be ensured so that hot water does not run out at all times, and the entrusted mode keeps the amount of hot water heated up at night and daytime optimally according to past usage results. For users with a small amount of hot water used, an operation mode in which boiling is performed only at night is suitable.

以上のように、使用者の使用湯量に応じて複数の運転モードを備えることによって、湯切れなく、快適に湯を使用することができる。   As described above, hot water can be used comfortably without running out of hot water by providing a plurality of operation modes according to the amount of hot water used by the user.

特開2004−233003号公報Japanese Patent Laid-Open No. 2004-233003

しかしながら、電力供給が安定した環境においては、前述の各運転モードは使用者の使用感を損ねることがないため有効な方法であるが、電力供給が安定しない環境においては、必ずしも有効であるとは言えない。   However, in an environment where the power supply is stable, each of the above operation modes is an effective method because it does not impair the user's feeling of use, but in an environment where the power supply is not stable, it is not necessarily effective. I can not say.

原子力を電源とする発電が停止する環境では需要を供給が越える場合が想定され、また、今後、益々増加すると見られる自然エネルギーを用いた発電は、季節や気象状況に依存
するため時間帯毎の供給量の差が激しい。
In an environment where power generation using nuclear power stops, it is assumed that the supply will exceed the demand, and power generation using natural energy, which is expected to increase in the future, depends on the season and weather conditions. There is a big difference in supply.

一般的に、電力需要が高まる季節は、夏期と冬期であり、夏期の電力需要のピークは気温が高くなって冷房需要が高まる午後2時前後である。また、冬期の電力需要のピークは気温が低くなって暖房需要が高まり、帰宅後の照明や厨房の需要と重なる午後5時頃から8時までである。   Generally, the season in which power demand increases is in summer and winter, and the peak power demand in summer is around 2 pm, when the air temperature increases and cooling demand increases. In addition, the peak of electric power demand in winter is from about 5:00 pm to 8:00 pm, when the temperature decreases and the demand for heating increases, overlapping with the demand for lighting and kitchen after returning home.

こういった電力ピークの状況を考慮しない、使用湯量のみに応じた運転モードでは、電力ピークの時間帯に沸き上げ運転要求が発生しても、沸き上げができない、または、使用者が沸き上げを手動で停止するために必要な湯量を確保できなかったり、湯切れを防止するために必要以上に沸き上げを行ってしまったりするおそれがある。   In the operation mode that only considers the amount of hot water used without considering the power peak situation, even if a boiling operation request occurs during the power peak time, boiling cannot be performed, or the user can boil it up. There is a risk that the amount of hot water necessary to stop manually cannot be secured, or the water is heated more than necessary to prevent hot water from running out.

本発明は、前記従来の課題を解決するもので、使用湯量のみならず、電力の需要バランスを考慮して沸き上げ運転が行える貯湯式給湯機を提供することを目的とする。   This invention solves the said conventional subject, and it aims at providing the hot water storage type hot water supply machine which can perform a boiling operation in consideration of not only the amount of hot water used but the demand balance of electric power.

前記従来の課題を解決するために、本発明の給湯装置は、貯湯槽と、前記貯湯槽内の湯水を加熱する加熱手段と、制御手段とを備え、使用湯量履歴に基づいて、前記加熱手段の加熱動作を変更するピークカット運転モードを有し、前記ピークカット運転モードとは異なる運転モードでは、前記加熱動作の動作を制限する時間帯において、前記加熱手段が加熱する湯水量の少なくとも一部を、前記ピークカット運転モードでは、前記加熱動作を制限すべき時間帯とは異なる時間帯において加熱することを特徴とするものである。   In order to solve the conventional problem, the hot water supply apparatus of the present invention includes a hot water storage tank, a heating means for heating the hot water in the hot water tank, and a control means, and the heating means is based on a history of hot water usage. In an operation mode different from the peak cut operation mode, at least a part of the amount of hot water heated by the heating means in a time zone that restricts the operation of the heating operation is provided. In the peak cut operation mode, the heating operation is performed in a time zone different from the time zone in which the heating operation should be limited.

これにより、ピークカット運転モードを、電力需給バランスを考慮したモードとすることで、使用湯量のみならず、電力の需要バランスに基づいた運転が行える貯湯式給湯機を提供することができる。   Thereby, by setting the peak cut operation mode to a mode that takes into account the power supply / demand balance, it is possible to provide a hot water storage type hot water heater that can be operated based not only on the amount of hot water used but also on the demand balance of power.

本発明によれば、使用湯量のみならず、電力の需要バランスを考慮して沸き上げ運転が行える貯湯式給湯機を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, not only the amount of hot water used but the demand balance of electric power can be considered and the hot water storage type water heater which can perform a boiling operation can be provided.

(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給湯装置の構成を示す図である。図1において、給湯装置は、貯湯槽1と、この貯湯槽1の湯水を加熱するヒートポンプ装置である加熱手段2と、加熱手段2の運転動作を制御する沸き上げ制御手段3と、沸き上げ制御手段3の制御方法を設定するリモコン4を備える。貯湯槽1の湯水は貯湯槽1の底部から沸き上げ配管11を通じて加熱手段2へ通水され、高温に沸き上げられた後に貯湯槽1の上部へ再び貯湯される。
(Embodiment 1)
FIG. 1 is a diagram showing a configuration of a hot water supply apparatus according to the first embodiment of the present invention. In FIG. 1, a hot water supply apparatus includes a hot water tank 1, a heating means 2 that is a heat pump device that heats hot water in the hot water tank 1, a boiling control means 3 that controls the operation of the heating means 2, and a boiling control. A remote controller 4 for setting the control method of the means 3 is provided. Hot water in the hot water tank 1 is passed from the bottom of the hot water tank 1 through the heating pipe 11 to the heating means 2, heated to a high temperature, and then stored again in the upper part of the hot water tank 1.

高温に沸き上げられた貯湯槽1内の湯水は、給湯栓13が開栓されると混合弁14によって給水配管からの給水と所定温度に混合されて給湯され、高温水が取り出されることによって貯湯槽1内で不足する湯水は、貯湯槽1の底部に給水配管から給水が供給され、貯湯槽1内は常に湯水で満たされる仕組みとなっている。   When the hot water tap 13 is opened, the hot water in the hot water tank 1 boiled at a high temperature is mixed with the water supplied from the water supply pipe by the mixing valve 14 at a predetermined temperature, and hot water is taken out. Hot water that is deficient in the tank 1 is supplied from the water supply pipe to the bottom of the hot water tank 1 so that the hot water tank 1 is always filled with hot water.

また、給湯栓13に接続する配管には、給湯流量検知手段22を備え、沸き上げ制御手段3は、使用湯量記憶手段31と季節判断手段32とカレンダー33と電力会社情報34を備え、カレンダー33が示す日付が、7月1日から9月30日であれば、季節判断手段32は、季節を夏期と判定する。   Further, the pipe connected to the hot water tap 13 is provided with a hot water supply flow rate detection means 22, and the boiling control means 3 is provided with a used hot water storage means 31, a season judgment means 32, a calendar 33, and electric power company information 34. If the date indicated is from July 1 to September 30, the season determination means 32 determines that the season is summer.

また、カレンダー33が示す日付が、12月1日から3月31日であれば、季節判断手段32は季節を冬期と判断する。使用湯量記憶手段31は、給湯流量検知手段22によって得られる使用湯量から、24時間分の使用湯量の履歴と、24時間を数時間帯に区切った時間毎の使用湯量の履歴とを記憶している。   If the date indicated by the calendar 33 is from December 1st to March 31st, the season determination means 32 determines that the season is winter. The hot water storage unit 31 stores a history of the amount of hot water used for 24 hours from the amount of hot water obtained by the hot water flow rate detection unit 22, and a history of the amount of hot water used for each hour divided into 24 hours. Yes.

また、24時間を計時するタイマー部が設けられており、このタイマー部により夜間時間帯、すなわち深夜電力時間帯(例えば、23時〜7時)と、湯切れ沸き上げ運転を行う昼間時間帯(7時〜23時)を設定している。   In addition, a timer unit for measuring 24 hours is provided. By this timer unit, a night time zone, that is, a midnight power time zone (for example, 23:00 to 7 o'clock), and a daytime time zone for performing a hot water boiling operation ( From 7:00 to 23:00).

以上のように構成された給湯について、以下その動作、作用を説明する。   About the hot water supply comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

図2にリモコン4のメニュー表示の例を示す。図2に示すように、使用者はリモコン4のメニューから沸き上げ設定を選択し、沸き上げモードの中からピークカット運転モードを選択する。   FIG. 2 shows an example of menu display on the remote controller 4. As shown in FIG. 2, the user selects the boiling setting from the menu of the remote controller 4, and selects the peak cut operation mode from the boiling mode.

図3に沸き上げ制御手段3で、ピークカット運転モードが選択された場合の処理の流れを示す。沸き上げ制御手段3では、Step1で、季節判断手段32がカレンダー情報から日付を取得し、日付が例えば、7月1日から9月30日の間であれば夏期と判断し、12月1日から3月31日であれば冬期と判断する。   FIG. 3 shows a processing flow when the peak cut operation mode is selected by the boiling control means 3. In the heating control means 3, in Step 1, the season judgment means 32 obtains the date from the calendar information, and if the date is between July 1 and September 30, for example, it is judged as summer and December 1 If it is March 31, it will be judged as winter.

次に、Step2で、消費電力の抑制を必要とする季節、つまり、夏期、または、冬期
であるかを判定する。夏期、または、冬期であれば、Step3で沸き上げ方法を変更する。中間期であれば、Step3の処理を行わない。
Next, in Step 2, it is determined whether it is a season in which power consumption needs to be suppressed, that is, summer or winter. If it is summer or winter, the boiling method is changed in Step 3. If it is an intermediate period, the processing of Step 3 is not performed.

図4を用いて、ピークカット運転モードが選択された場合の沸き上げ方法の概念を説明する。図4の(a)は通常モードの場合の沸き上げ時間帯と量を示し、(b)はピークカット運転モードが選択され、かつ、使用湯量の少ない場合の沸き上げ時間と量を示す。(c)はピークカット運転モードが選択され、かつ、使用湯量の多い場合の沸き上げ時間と量を示す。   The concept of the boiling method when the peak cut operation mode is selected will be described with reference to FIG. 4A shows the boiling time zone and amount in the normal mode, and FIG. 4B shows the boiling time and amount when the peak cut operation mode is selected and the amount of hot water used is small. (C) shows the boiling time and amount when the peak cut operation mode is selected and the amount of hot water used is large.

元々、使用湯量が少ない場合は湯余りを防止するために、夜間はタンク全体を沸き上げない。例えば、図4の(a)に示す量を沸き上げる。しかし、想定していた使用湯量よりも多く湯が使用される場合は、昼間に追加で沸き上げる(例えば、図4の(a)に示す量)。夜間と昼間の沸き上げのバランスを取ることによって、過不足なく沸き上げを行うことを実現している。   Originally, when the amount of hot water used is small, the entire tank is not boiled at night in order to prevent excess hot water. For example, the amount shown in FIG. However, if more hot water is used than the amount of hot water used, the water is additionally boiled in the daytime (for example, the amount shown in FIG. 4A). By balancing the nighttime and daytime boiling, it is possible to boil without excess or deficiency.

しかし、ピークカット運転モードが選択されている場合は、湯切れさせずに昼間の沸き上げ量の抑制も行わなければならないため、図4の(b)に示すように、昼間に沸き上げる量を夜間にシフトさせて沸き上げる方法をとる。   However, when the peak cut operation mode is selected, it is necessary to suppress the amount of boiling during the day without running out of hot water. Therefore, as shown in FIG. Shift to night and take a method of boiling.

一方、使用湯量の多い場合は、元々、夜間の沸き上げ量はタンク全体の水を沸き上げているため、夜間の沸き上げ量を増加させることはできない。そのため、図4の(c)に示すように、沸き上げを抑制する時間帯が終了した時に、沸き上げを開始して湯切れを防止する方法となる。   On the other hand, when the amount of hot water used is large, the amount of boiling at night cannot be increased because the amount of boiling at night originally boiled the water in the entire tank. Therefore, as shown in FIG. 4 (c), when the time zone for suppressing the boiling is over, the boiling is started to prevent the hot water from running out.

昼間の沸き上げ開始の条件は、使用湯量の大小両方の場合でタンク内の残湯量が時間帯別に設定している最低残湯量よりも少なくなる場合である。このことにより、昼間の電力需要の大きい時間帯に電力を消費することがなく、使用者の利便性を損なう湯切れも防止することができる。   The condition for starting boiling in the daytime is when the amount of hot water in the tank is smaller than the minimum amount of hot water set for each time zone in both cases of the amount of hot water used. As a result, power is not consumed during the daytime when there is a great demand for electric power, and it is possible to prevent running out of hot water that impairs the convenience of the user.

図5に沸き上げ方法の変更処理を示すフロー図を示し、沸き上げ方法変更の処理の流れを説明する。まず、Step31で使用湯量記憶手段31が記憶している使用湯量の判断を行う。使用湯量が少ない場合は、Step32で夜間沸き上げ量を増やし、Step33へ進む。使用湯量が多い場合は、Step32の処理を行わず、Step33へ進む。Step33では、時間帯別の最低残湯量を変更する。   FIG. 5 is a flow chart showing the process for changing the boiling method, and the flow of the process for changing the boiling method will be described. First, in step 31, the hot water usage stored in the hot water storage means 31 is determined. When the amount of hot water used is small, the amount of boiling at night is increased at Step 32, and the process proceeds to Step 33. If the amount of hot water used is large, the process proceeds to Step 33 without performing the process of Step 32. In Step 33, the minimum remaining hot water amount for each time zone is changed.

次に、時間帯別の最低残湯量の変更例について図6を用いて説明する。図6の(a)は通常の沸き上げモードであるおまかせモードの場合の最低残湯量の例であり、図6(b)はピークカット運転モードで使用湯量の少ない場合の最低残湯量の例で、図6の(c)はピークカット運転モードで、使用湯量の多い場合の最低残湯量の例である。   Next, an example of changing the minimum remaining hot water amount for each time zone will be described with reference to FIG. FIG. 6 (a) is an example of the minimum remaining hot water amount in the case of the entrusted mode which is a normal boiling mode, and FIG. 6 (b) is an example of the minimum remaining hot water amount when the amount of hot water used is small in the peak cut operation mode. (C) of FIG. 6 is an example of the minimum remaining hot water amount when the amount of hot water used is large in the peak cut operation mode.

ピークカット運転モードが選択されている場合は、図6の(a)で280Lと設定されている時間帯の2と3の最低残湯量を、沸き上げをしないように、例えば負の値である−100Lに設定する(タンク内の残湯量は負の値にはならない)。   When the peak cut operation mode is selected, the minimum remaining hot water amount 2 and 3 in the time zone set to 280 L in FIG. 6A is, for example, a negative value so as not to be heated. Set to -100L (the amount of hot water in the tank is not negative).

もし、湯切れぎりぎりで沸き上げをしたい場合は、0Lに設定してもよい。ピークカット運転モードで使用湯量が少ない場合は、夜間の沸き上げ量を増加させているため、図6の(b)で設定しているように時間帯の4の最低残湯量は変更しない。使用湯量が多い場合は、夜間の沸き上げ量に変更はないため、時間帯4の最低残湯量は、図6の(c)の時間帯4と時間帯5の使用湯量を合計した280Lに設定する。   If you want to boil up just after the hot water break, you may set to 0L. When the amount of hot water used is small in the peak cut operation mode, the amount of boiling at night is increased, so that the minimum remaining hot water amount of 4 in the time zone is not changed as set in FIG. When the amount of hot water used is large, there is no change in the amount of boiling at night, so the minimum remaining hot water amount in time zone 4 is set to 280 L, which is the sum of the amount of hot water used in time zones 4 and 5 in FIG. To do.

これによって、時間帯3で湯が使用されてタンク内の残湯量が少なくなっていたとしたら、時間帯4の最低残湯量が多めの設定で、早めに沸き上げるようになるため、時間帯が切り替わる時点で沸き上げが開始される。   As a result, if hot water is used in time zone 3 and the amount of remaining hot water in the tank is small, the minimum remaining hot water amount in time zone 4 is set to a large amount, so that it will boil up early, so the time zone changes. At that point, boiling begins.

残湯量を多めに設定することにより、湯切れを最小限に留めることができ、使用湯量に基づいて設定しているため、沸き上げ過ぎて湯余りになることも防止できる。   By setting the remaining amount of hot water to a large amount, it is possible to keep the hot water from running out to a minimum, and since it is set based on the amount of hot water used, it is possible to prevent excessive boiling and excess water.

以上ように、本発明によれば、沸き上げ運転モードにピークカット運転モードを備え、季節や使用状態に基づいて夜間の沸き上げ量や昼間の最低残湯量を変更することによって、使用者の利便性を損なうことなく、電力消費の抑制を行うことができる。   As described above, according to the present invention, the boiling operation mode is provided with the peak cut operation mode, and the convenience of the user is changed by changing the amount of boiling at night and the minimum amount of hot water during the day based on the season and usage conditions. Power consumption can be suppressed without impairing the performance.

従って、社会的な観点から見ても、電力の需給バランスを保つことができ、安定的な電力供給状態を実現することができる。   Therefore, even from a social point of view, it is possible to maintain a power supply / demand balance and realize a stable power supply state.

なお、原子力や火力、自然エネルギーなど電源別の発電割合によって変わってくるため、消費電力抑制を行わなければならない必要性は、電力会社によって異なる。   In addition, since it changes with the electric power generation ratio according to power sources, such as nuclear power, thermal power, and natural energy, the necessity to perform power consumption control changes with electric power companies.

そのため、電力会社情報34であらかじめ記憶している電力会社の情報から、抑制すべき電力量の程度を判断し、電力会社毎に最低残湯量を変更してもよい。また、抑制すべき時間帯も電力会社によって異なることが考えられるため、沸き上げを抑制する時間帯や時間帯の区切りも電力会社によって変更するようにすれば、現実に即したより高い効果が得られる。   Therefore, the level of the amount of power to be suppressed may be determined from the information on the power company stored in advance in the power company information 34, and the minimum remaining hot water amount may be changed for each power company. In addition, the time zone to be suppressed may vary depending on the electric power company. Therefore, if the electric power company also changes the time zone and the time zone delimiter that suppresses boiling, a higher effect in reality can be obtained. It is done.

また、使用湯量が多い場合、最低残湯量を増加する時間帯は、消費電力を抑制すべき時間帯の終わった時間帯としたが、場合によっては抑制すべき時間帯の前でも良い。   In addition, when the amount of hot water used is large, the time zone for increasing the minimum remaining hot water amount is the time zone when the time zone for which power consumption should be suppressed ends, but may be before the time zone for which power consumption should be suppressed depending on circumstances.

図7では、外気温度検知手段24と給水温度検知手段21を持ち、季節判断手段32が、外気温と給水温度の情報から、例えば、1日の平均外気温が15℃以下、または、給水温度が14℃以下の場合に冬期と判断し、1日の平均外気温が25℃以上、または、給水温度が24℃以上の場合に夏期と判断する。   In FIG. 7, it has the outside temperature detection means 24 and the feed water temperature detection means 21, and the season judgment means 32 is, for example, the average outside temperature per day is 15 ° C. or less or the feed water temperature based on the information on the outside temperature and the feed water temperature. Is determined to be winter when the temperature is 14 ° C. or lower, and summer is determined when the daily average outside air temperature is 25 ° C. or higher or the water supply temperature is 24 ° C. or higher.

また、図8では、季節判断手段32は、使用湯量記憶手段31によって記憶されている使用湯量から季節を判断する。例えば、年間の平均的な1日の使用湯量に対して1日の使用湯量が1.5倍になった場合に冬期と判断し、0.8倍となった場合に夏期と判断する。   In FIG. 8, the season determination unit 32 determines the season from the amount of hot water stored in the hot water storage unit 31. For example, when the daily hot water volume is 1.5 times the average daily hot water volume of the year, it is determined that it is winter, and when it is 0.8 times, it is determined that it is summer.

このように、ピークカット運転モードを行う季節を外気温や給水温度の条件を用いて判断することによって、冷夏や暖冬といった年毎に異なる気象の変化や、給湯装置の設置地域の違いに関わらず、消費電力量の多くなる時期、少なくなる時期を判断することができるため、消費電力量を抑制する必要がある時期を的確に判断することができる。なお、使用湯量を使用熱量に換算して用いても良い。   In this way, by determining the season in which the peak cut operation mode is performed using the conditions of the outside air temperature and the water supply temperature, regardless of the change in weather such as cold summer and warm winter and the difference in the area where the water heater is installed, Since it is possible to determine when the power consumption increases or decreases, it is possible to accurately determine when it is necessary to suppress the power consumption. The amount of hot water used may be converted into the amount of heat used.

図9では、電力供給業者が予測する翌日の時刻毎の電力需給情報を取得する電力需給情報取得手段35を備え、供給量に対する消費量の割合である利用率が85%以上である時間帯と、使用湯量記憶手段31に記憶している使用湯量から夜間沸き上げ量と昼間の最低残湯量を変更する。   In FIG. 9, a power supply / demand information acquisition unit 35 that acquires power supply / demand information for each time of the next day predicted by the power supplier is provided, and a usage period that is a ratio of consumption to supply is 85% or more. Then, the amount of boiling water at night and the minimum amount of remaining hot water during the day are changed from the amount of hot water stored in the hot water storage means 31.

このように、ネットワークから消費電力抑制情報を随時取得できるため、日々変化する電力の需給バランスに対応することができる。そのため、使用者の利便性を損なうことなく、より的確に昼間の消費電力量抑制に対応することができる。   As described above, since the power consumption suppression information can be acquired from the network at any time, it is possible to cope with the power supply / demand balance that changes daily. For this reason, it is possible to more accurately cope with daytime power consumption suppression without impairing the convenience of the user.

なお、ネットワークから取得する電力需給情報は、自然エネルギーを電源とする発電の割合が多い場合、天候の急な変化によって発電量も大きく変化する。そのため、消費電力時々刻々と取得して、沸き上げ方法を随時変更するようにしても良い。   Note that, in the power supply and demand information acquired from the network, when the proportion of power generation using natural energy as a power source is large, the amount of power generation greatly changes due to a sudden change in weather. Therefore, power consumption may be acquired every moment, and the boiling method may be changed as needed.

以上のように、本発明にかかる給湯装置は、消費電力抑制が必要な場合に利用者の利便性を損なうことなく、電力の消費時刻を変更することができるため、貯湯槽を有する給湯システムにおいて業務用などの規模の大きい用途にも適用が可能である。   As described above, the hot water supply apparatus according to the present invention can change the power consumption time without impairing the convenience of the user when the power consumption must be suppressed. It can also be applied to large-scale uses such as business use.
