前述の公報に示されるような従来の循環式温水利用装置では、深夜電力時間帯 等の特定時間帯において加熱して貯湯した温水タンク内の湯の熱量だけで、熱交 換器に導かれてくる湯（例えば浴槽から供給されてくる湯）を十分に再加熱でき ると考えていた。しかしながら、盆暮れのように来客が多い場合や、冬に湯を用 いて多量の洗濯をする場合等には、温水器の温水タンク内に貯湯した湯が大量に 使われて湯量不足が発生することがある。このような場合には、温水タンク内の 湯温が低下するため、熱交換器を利用して熱交換器に導かれてくる湯を所望の温 度まで再加熱することができなくなる不都合が生じる。 本考案の目的は、貯湯式電気温水器内の湯が大量に使用された場合でも、熱交 換器に導かれてくる湯を所望の温度まで再加熱することができる循環式温水利用 装置を提供することにある。 In the conventional circulating hot water utilization device as disclosed in the above publication, only the heat quantity of the hot water in the hot water tank, which is heated and stored in a specific time zone such as the midnight power time zone, is introduced to the heat exchanger. I thought that the hot water coming from the bath (for example, the water supplied from the bathtub) could be reheated sufficiently. However, when there are many visitors, such as in the summer, and when washing a large amount of hot water in the winter, a large amount of hot water stored in the hot water tank of the water heater is used, causing a shortage of hot water. There is. In such a case, the temperature of the hot water in the hot water tank will drop, and there will be an inconvenience that the hot water introduced to the heat exchanger cannot be reheated to the desired temperature using the heat exchanger. .. An object of the present invention is to provide a circulating hot water utilization device that can reheat hot water introduced to a heat exchanger to a desired temperature even if a large amount of hot water in a hot water storage electric water heater is used. To provide.

【課題を解決するための手段】 請求項１の考案は、温水タンク内の下部領域にメインヒータを備え温水タンク 内の上部領域に熱交換器を備えた貯湯式電気温水器と、貯湯式電気温水器から供 給された温水を熱交換器により再加熱して利用する温水循環式風呂機器等の温水 循環利用機器とからなる循環式温水利用装置を改良の対象として、貯湯式電気温 水器の温水タンク内の上部領域内の熱交換器より下の位置に追い焚き用ヒータを 設けることを特徴とする。 請求項２の考案では、追い焚き用ヒータへの通電の停止を決定する情報を得る ために温水タンク内の上部領域内の湯温を測定する温度センサを、熱交換器より も上に位置する温水タンクの上壁部に設ける。 請求項３の考案では、請求項１の考案を実施する場合において、特に貯湯式電 気温水器として、温水タンク内の下部領域に配置されたメインヒータと、温水タ ンク内の上部領域に配置された熱交換器と、温水タンク内の上部領域内の前記熱 交換器よりも下の位置に配置された追い焚き用ヒータと、設定に応じて追い焚き 指令を含む制御指令を出力する温水器用制御設定装置と、メインヒータ及び追い 焚き用ヒータの通電を制御し且つ追い焚き指令が入力されている場合に所定の制 御モードに従って前記追い焚き用ヒータの通電制御を行うヒータ通電制御装置と を有してなる貯湯式電気温水器を用いる場合に生じる問題を解決する。この温水 器は、温水器用制御設定装置の設定により追い焚きを行うか否かを選択できる機 能を有している。そこで本考案においては、温水循環利用機器が作動状態にある か否かを検出して作動状態を検出すると追い焚き指令をヒータ通電制御装置に出 力する追い焚き指令発生装置を設け、ヒータ通電制御装置が温水器用制御設定装 置及び前記追い焚き指令発生装置のいずれからも追い焚き指令を入力し得るよう に構成する。According to a first aspect of the present invention, there is provided a hot water storage electric water heater having a main heater in a lower region of a hot water tank and a heat exchanger in an upper region of the hot water tank, and a hot water storage electric device. A hot water storage electric water heater is targeted for improvement of a circulating hot water utilization device consisting of hot water circulating bath equipment such as hot water circulating bath equipment that reheats hot water supplied from a water heater using a heat exchanger. It is characterized in that a reheating heater is provided in a position below the heat exchanger in the upper region of the hot water tank. According to the second aspect of the present invention, the temperature sensor for measuring the hot water temperature in the upper region of the hot water tank is located above the heat exchanger in order to obtain the information for determining the stop of the energization of the reheating heater.

請求項１の考案によれば、大量の湯の使用によって、いわゆる湯切れが発生し 、熱交換器が配置された温水タンク内の上部領域の湯温が低下した場合に、追い 焚き用ヒータを発熱させることにより、短時間に上部領域内の湯温を高めること ができる。そのため熱交換器に導かれる湯を確実に再加熱できる。 請求項２の考案のように、追い焚きヒータ停止制御用の温度センサを熱交換器 よりも上に位置する温水タンクの上壁部に設けると、追い焚き時における湯の沸 騰の発生を確実に防止できる。熱交換器がない状態で追い焚き用ヒータが用いら れる場合と比べて、熱交換器を利用した場合には、熱交換器を通しての熱損失が 発生する。そのため、予め熱交換器による熱損失を見込んで、追い焚き用ヒータ から放出させる熱カロリの量を多くせざるを得ない。そして追い焚き用ヒータへ の通電の停止は、温水タンク内の上部領域に配置した温度センサが設定温度を検 出したときに行うことになる。しかしながら追い焚き用ヒータのすぐ上の位置に 温度センサを配置した場合、温度センサが適温を検出したときには、すでに上部 領域内の最も上の部分に位置する湯の温度が１００℃以上になって湯の沸騰が発 生することがある。温度センサを熱交換器よりも上に位置する温水タンクの上壁 部に設ければ、湯が沸騰する前に確実に追い焚き用ヒータへの通電を停止するこ とができ、安全性が高くなる。 追い焚き用ヒータを備えた貯湯式電気温水器が、リモートコントローラ等の温 水器用制御設定装置の設定により追い焚きを行うか否かを選択できる機能を有し ている場合に、温水器用制御設定装置により追い焚きを設定していないと、いく ら追い焚き用ヒータを備えていても、温水タンク内の湯温が低下して熱交換器に 導かれる湯の再加熱が不可能な状態になったときに、追い焚きが開始されない問 題が生じる。請求項３の考案のように、温水循環式風呂機器等の温水循環利用機 器が作動状態にあるか否かを検出して作動状態を検出すると追い焚き指令をヒー タ制御装置に出力する追い焚き指令発生装置を設け、ヒータ通電制御装置を温水 器用制御設定装置及び追い焚き指令発生装置のいずれからも追い焚き指令を入力 し得るように構成すれば、温水循環利用機器が作動して熱交換器による湯の再加 熱が必要なときには、必ず追い焚きが可能な状態を維持することができる。よっ て請求項３の考案によれば、温水器用制御設定装置の設定により追い焚きを行う か否かを選択できる機能を有している貯湯式電気温水器を熱源として用いる場合 に生じる上記問題を解消できる。 According to the invention of claim 1, when a large amount of hot water is used and so-called hot water runs out, and the hot water temperature in the upper region in the hot water tank in which the heat exchanger is arranged is lowered, a heater for heating the reheating is provided. By generating heat, the hot water temperature in the upper region can be raised in a short time. Therefore, the hot water guided to the heat exchanger can be reliably reheated. When the temperature sensor for controlling the stop heating of the reheating heater is provided on the upper wall portion of the hot water tank located above the heat exchanger as in the invention of claim 2, the boiling of the hot water at the time of reheating is surely generated. Can be prevented. Compared to the case where the reheating heater is used without the heat exchanger, heat loss through the heat exchanger occurs when the heat exchanger is used. Therefore, it is inevitable to increase the amount of heat calories to be discharged from the reheating heater in consideration of the heat loss due to the heat exchanger in advance. The energization of the reheating heater is stopped when the temperature sensor located in the upper area of the hot water tank detects the set temperature. However, when the temperature sensor is placed just above the reheating heater, when the temperature sensor detects an appropriate temperature, the temperature of the hot water already located at the uppermost part in the upper region becomes 100 ° C or higher. Boiling may occur. If a temperature sensor is installed on the upper wall of the hot water tank located above the heat exchanger, it is possible to reliably stop the energization of the reheating heater before the boiling water comes out, resulting in high safety. Become. If the hot water storage type electric water heater equipped with a heater for reheating has a function that allows you to select whether or not to reheat by setting the control setting device for the water heater such as a remote controller, If reheating is not set by the device, no matter how many reheating heaters are provided, the temperature of the hot water in the hot water tank will drop and it will not be possible to reheat the hot water introduced to the heat exchanger. There is a problem that reheating does not start. As in the invention of claim 3, it is detected whether or not the hot water circulating type equipment such as the hot water circulating bath equipment is in the operating state, and when the operating state is detected, the additional heating command is output to the heater control device. If a heating command generator is installed and the heater energization control device is configured to be able to input a heating command from both the water heater control setting device and the additional heating command generator, the hot water circulating device will operate and heat exchange will occur. When it is necessary to reheat the hot water with a vessel, it is possible to maintain a state where it can be reheated. Therefore, according to the invention of claim 3, the above-mentioned problem that occurs when a hot water storage type electric water heater having a function of selecting whether to perform reheating by setting the control setting device for the water heater is used as a heat source. It can be resolved.

The hot water storage type electric water heater 1 includes a main heater 1c in a lower region of a hot water tank 1b arranged inside the outer case 1a. The main heater 1c is a midnight heater that heats the water in the hot water tank 1b to a predetermined temperature during a so-called midnight power time period. A first temperature sensor 1d used for controlling energization stop of the main heater 1c is provided in a portion of the hot water tank 1b just above the main heater 1c. The main heater 1c is energized by a heater energization controller (not shown).

A water level sensor 3a is attached in the middle of the upstream pipe 4a. The water level sensor 3a determines the water level in the bathtub 2 based on the water pressure, and outputs an operation stop command to the control circuit 3b when the amount of hot water in the bathtub 2 is below the minimum water level L. A circulation pump 3c is arranged in the middle of the upstream pipe 4a, and the circulation pump 3c is operation-controlled according to a command from the control circuit 3b to circulate the hot water in the bathtub 2 through the heat exchanger 1e. .. A temperature sensor 3d is arranged in the return pipe 4b. The temperature sensor 3d measures the temperature of the hot water in the bath tank 2. When the hot water temperature measured by the temperature sensor 3d falls below a predetermined lower limit temperature, the control circuit 3b drives the circulation pump 3c to circulate the hot water. When the hot water temperature measured by the temperature sensor 3d reaches a predetermined upper limit temperature, the control circuit 3b stops the circulation pump 3c to stop the hot water circulation. The control circuit 3b enters an operating state when the power switch of the remote controller 3e is turned on, and stops operating when the power switch is turned off.
【０００８】 リモートコントローラ３ｅの電源スイッチが投入されて温水循環制御装置３が 作動状態になっている状態で、貯湯式電気温水器１の温水タンク１ｂ内の湯が大 量に使用されて、熱交換器１ｅが配置されている温水タンク１ｂ内の上部領域の 湯温が大幅に低下すると、熱交換器１ｅを用いて浴槽２の湯を所望の温度まで再 加熱することができなくなる。本実施例では、このような状態になる前または後 で、追い焚き用ヒータ１ｆを発熱させることにより、温水タンク１ｂ内の上部領 域の湯温を短時間のうちに上昇させることができるため、熱交換器１ｅによる浴 槽２内の湯の再加熱を短時間に再開することができる。また第２の温度センサ１ ｇを温水タンク１ｂの上壁部に取付けているため、温水タンク１ｂ内の上部領域 の湯が沸騰する前に追い焚き用ヒータの通電を停止することができる。When the power switch of the remote controller 3e is turned on and the hot water circulation control device 3 is in the operating state, a large amount of hot water in the hot water tank 1b of the hot water storage electric water heater 1 is used to generate heat. If the temperature of the hot water in the upper region of the hot water tank 1b in which the exchanger 1e is arranged drops significantly, the hot water in the bathtub 2 cannot be reheated to a desired temperature by using the heat exchanger 1e. In the present embodiment, the hot water temperature of the upper region in the hot water tank 1b can be raised in a short time by heating the reheating heater 1f before or after such a state. The reheating of the hot water in the bath 2 by the heat exchanger 1e can be restarted in a short time. Further, since the second temperature sensor 1g is attached to the upper wall portion of the hot water tank 1b, the energization of the reheating heater can be stopped before the hot water in the upper region of the hot water tank 1b boils.

However, when the hot water storage type electric water heater 1 has a function to select whether or not to perform reheating by setting the remote controller or the control setting device for the water heater such as the control instruction panel, reheating is performed. If this setting is not set, no matter how many heaters are provided for reheating, the temperature of the hot water in the hot water tank drops and it becomes impossible to reheat the hot water introduced to the heat exchanger. Sometimes, there is a problem that reheating does not start. FIG. 2 is a block diagram showing an outline of a control system of an embodiment capable of solving such a problem.

To do. The specific reheating command generation device 12 is, for example, a circuit that determines whether or not the hot water circulation utilization device is operating depending on whether or not the power switch of the remote controller 3e is closed and the hot water circulation control device 3 is powered on. Alternatively, it is possible to use a circuit in which an operating state display signal generating circuit is built in the control circuit 3b to detect the presence or absence of an operating state display signal from the circuit and determine whether the hot water circulation utilizing device is operating or not. it can. When the reheating is set by the setting switch, the hot water heater control setting device 1h including a remote controller outputs a reheating command to the heater energization control device 1m.

請求項１の考案によれば、大量の湯の使用によって、熱交換器が配置された温 水タンク内の上部領域の湯温が低下した場合に、追い焚き用ヒータを発熱させる ことにより、短時間に上部領域内の湯温を高めることができ、熱交換器に導かれ る湯を確実且つ短時間のうちに再加熱することができる利点がある。 請求項２の考案によれば、追い焚きヒータ停止制御用の温度センサを熱交換器 よりも上に位置する温水タンクの上壁部に設けたので、追い焚き時における湯の 沸騰の発生を防止できる利点がある。 請求項３の考案によれば、温水器用制御設定装置の設定により追い焚きを行う か否かを選択できる機能を有している貯湯式電気温水器を用いる場合において、 温水器用制御設定装置の設定により追い焚きが設定されていないときでも、熱交 換器に導かれる湯を再加熱するために追い焚きが必要なときには、追い焚きを行 える利点がある。 According to the invention of claim 1, when the hot water temperature in the upper region in the hot water tank in which the heat exchanger is arranged is lowered by the use of a large amount of hot water, the reheating heater is caused to generate heat, thereby shortening the heating time. There is an advantage that the temperature of the hot water in the upper region can be increased in time and the hot water introduced to the heat exchanger can be reheated reliably and in a short time. According to the invention of claim 2, since the temperature sensor for controlling the reheating heater is provided on the upper wall portion of the hot water tank located above the heat exchanger, the boiling of the hot water during the reheating operation is prevented. There are advantages. According to the invention of claim 3, in the case of using a hot water storage type electric water heater having a function of selecting whether or not to perform additional heating by setting of the water heater control setting device, the water heater control setting device is set. Therefore, even if the reheating is not set, there is an advantage that the reheating can be performed when the reheating is required to reheat the hot water guided to the heat exchanger.
