図１おいて、１０はステンレスからなる円筒状の密閉タンクである。上面１０ａと下面１０ｂは略平面の円盤で、側面１０ｃにより上下に繋がっている。タンク１０は、外側をグラスウール等の断熱材（図示せず）で囲い、電気温水器１に固定されている。 In FIG. 1, reference numeral 10 denotes a cylindrical sealed tank made of stainless steel. The upper surface 10a and the lower surface 10b are substantially flat disks, and are connected vertically by the side surface 10c. The tank 10 is fixed to the electric water heater 1 by enclosing the outside with a heat insulating material (not shown) such as glass wool.
タンク１０内には蓄熱材として有機潜熱蓄熱材２が充満されている。有機潜熱蓄熱材２は例えばポリエチレングリコールである。ポリエチレングリコールは、比重：１．１９（ｇ／ｃｍ3）、比熱：２．３０（Ｊ／ｇ・℃）、融解熱：１９３（Ｊ／ｇ）である。 The tank 10 is filled with the organic latent heat storage material 2 as a heat storage material.

Polyethylene glycol has a specific gravity of 1.19 (g / cm 3 ), a specific heat of 2.30 (J / g · ° C.), and a heat of fusion of 193 (J / g).
タンク１０の内部には、水道から供給され水圧を有する冷水を有機潜熱蓄熱材２で熱交換する吸熱管４を設けている。この吸熱管４は銅管からなり、銅管を螺旋状に成形してタンク１０の略中心に垂直に設けている。吸熱管４の上方には入口部４ｂと下方に出口部４ｄを設けている。入口部４ｂはタンク１０の上面１０ａに、出口部４ｃはタンク１０の下面１０ｂに貫通してロウ付けにより気密接合して固定している。 Inside the tank 10, there is provided a heat absorption pipe 4 for exchanging heat of cold water having a water pressure supplied from the water supply by the organic latent heat storage material 2. The endothermic tube 4 is made of a copper tube, and the copper tube is formed in a spiral shape and provided perpendicular to the approximate center of the tank 10. An inlet portion 4b is provided above the heat absorption tube 4, and an outlet portion 4d is provided below. The inlet portion 4b penetrates the upper surface 10a of the tank 10 and the outlet portion 4c penetrates the lower surface 10b of the tank 10 and is hermetically joined and fixed by brazing.
また、タンク１０の内部には、有機潜熱蓄熱材２を加熱する電気発熱体３を設けている。この電気発熱体３はＵ字状に成形されており、タンク１０の略中心に垂直に設けることで、吸熱管４の螺旋の内側に設けている。そして、タンク１０の下面１０ｂにＵ字状の２つの端部３ａを固定して設ける。タンク１０の下面１０ｂと電気発熱体３の接合部はロウ付けで気密接合してある。 An electric heating element 3 for heating the organic latent heat storage material 2 is provided inside the tank 10. The electric heating element 3 is formed in a U shape, and is provided inside the spiral of the heat absorption tube 4 by being provided perpendicular to the substantial center of the tank 10. Then, two U-shaped end portions 3 a are fixedly provided on the lower surface 10 b of the tank 10. The joint between the lower surface 10b of the tank 10 and the electric heating element 3 is airtightly joined by brazing.
この構成において、タンク１０に構成された部品構成を中心から順に示すと、中心部に有機潜熱蓄熱材２、その外にＵ字状の電気発熱体３、その外に有機潜熱蓄熱材２、その外に吸熱管４、その外に有機潜熱蓄熱材２、そしてタンク１０の側面１０ｃとなる。 In this configuration, when the components configured in the tank 10 are shown in order from the center, the organic latent heat storage material 2 at the center, the U-shaped electric heating element 3 outside, the organic latent heat storage material 2 outside, It becomes the heat absorption pipe 4 outside, the organic latent heat storage material 2 outside, and the side face 10 c of the tank 10.
５はサーミスタ等をケースに封止した温度センサーで、タンク１０の上面１０ａに固定し、タンク１０内に満たした有機潜熱蓄熱材２の温度を検知する。温度センサー５は、後述の電子制御装置６に電気的に接続されている。６は電子制御装置で、電源を外部の商用電源１１から入力され、温度センサー５の出力を入力されて電気発熱体２の出力を制御する。また、電子制御装置６は水路１２に設けて、水路１３に水を流すまたは止めるように開閉弁９を動作する。 Reference numeral 5 denotes a temperature sensor having a thermistor or the like sealed in a case, which is fixed to the upper surface 10 a of the tank 10 and detects the temperature of the organic latent heat storage material 2 filled in the tank 10. The temperature sensor 5 is electrically connected to an electronic control device 6 described later. An electronic control unit 6 receives power from an external commercial power source 11 and receives an output from the temperature sensor 5 to control an output from the electric heating element 2. Further, the electronic control device 6 is provided in the water channel 12 and operates the on-off valve 9 so as to flow or stop water in the water channel 13.
次に、水の経路について説明する。水路１３は開閉弁９を経て分流装置７へ流れる。分流装置７の一方は送水部４ａに接続し、送水部４ａから入口部４ｂに接続し、入口部４ｂから吸熱管４に接続し、吸熱管４から出口部４ｂに接続し、出口部４ｂから吐出部４ｅに接続し、吐出部４ｅは混合装置８に接続している。 Next, the water path will be described. The water channel 13 flows to the flow dividing device 7 through the on-off valve 9. One of the flow dividing devices 7 is connected to the water supply section 4a, connected from the water supply section 4a to the inlet section 4b, connected from the inlet section 4b to the heat absorption pipe 4, connected from the heat absorption pipe 4 to the outlet section 4b, and from the outlet section 4b The discharge unit 4e is connected to the discharge unit 4e, and the discharge unit 4e is connected to the mixing device 8.

A hot water supply port 11 is connected to the mixing device 8. The mixing device 8 is provided on the hot water output side of the tank 10 and mixes hot water from the heat absorption tube 4 and cold water sent from the flow dividing device 7 through the mixing tube 12 to obtain an appropriate temperature.
以上のように構成する電気温水器１の動作を説明する。 Operation | movement of the electric water heater 1 comprised as mentioned above is demonstrated.
電気温水器１に商用電源１１に接続し、主スイッチ（図示せず）を入れ運転中となると電子制御装置６の制御により電気発熱体３に通電する。電気発熱体３の発熱により有機潜熱蓄熱材２を加熱する。タンク上面１０ａに設けた温度センサー５で有機潜熱蓄熱材２の温度を検知し、電子制御装置６に出力される。電子制御装置６は温度センサー５の入力によって有機潜熱蓄熱材２の温度が約８５−９５℃を維持するように電気発熱体３の通電を制御する。そのため電気温水器１の運転中は、タンク１０内の有機潜熱蓄熱材２は約８５−９５℃で保温される。 When the electric water heater 1 is connected to the commercial power source 11 and a main switch (not shown) is turned on and the operation is in progress, the electric heating element 3 is energized under the control of the electronic control unit 6. The organic latent heat storage material 2 is heated by the heat generated by the electric heating element 3. The temperature sensor 5 provided on the tank upper surface 10 a detects the temperature of the organic latent heat storage material 2 and outputs it to the electronic control device 6. The electronic control unit 6 controls the energization of the electric heating element 3 so that the temperature of the organic latent heat storage material 2 is maintained at about 85-95 ° C. by the input of the temperature sensor 5. Therefore, during the operation of the electric water heater 1, the organic latent heat storage material 2 in the tank 10 is kept at a temperature of about 85-95 ° C.
そして、給湯が必要な場合に給湯ボタン（図示せず）等の操作により電子制御装置６は
開閉弁９を動作させる。開閉弁９が開状態となり、分流装置、送水部４ａ、入口部４ｂ、を経てタンク１０内の吸熱管４に冷水が供給される。吸熱管４内を流れる冷水は、加温された有機潜熱蓄熱材２から吸熱管４を介して熱を受取ることで温度上昇する。そして出口部４ｄ、吐出部４ｅを経て混合装置８に流入する。そして、分流装置７から分岐して混合管１２を経て供給される冷水と混合され目的の適温となって給湯口１１に供給される。混合装置８は吐出部４ｅの湯と、混合管１２の冷水の流れる量の割合を調整することで使用者の目的の温度の給湯を得るものである。
And when hot water supply is required, the electronic controller 6 operates the on-off valve 9 by operating a hot water supply button (not shown) or the like. The on-off valve 9 is opened, and cold water is supplied to the heat absorption pipe 4 in the tank 10 through the flow dividing device, the water supply section 4a, and the inlet section 4b. The cold water flowing in the heat absorption pipe 4 rises in temperature by receiving heat from the heated organic latent heat storage material 2 via the heat absorption pipe 4. And it flows in into the mixing apparatus 8 through the exit part 4d and the discharge part 4e. Then, the water is branched from the flow dividing device 7 and mixed with the cold water supplied through the mixing pipe 12 to be supplied to the hot water supply port 11 at an appropriate temperature. The mixing device 8 obtains hot water at a target temperature of the user by adjusting the ratio of the amount of hot water in the discharge section 4e and the amount of cold water flowing in the mixing tube 12.
１回の給湯動作によって、タンク１０内の有機潜熱蓄熱材２の熱量が冷水を流した吸熱管４によって奪われて、有機潜熱蓄熱材２の温度が下がる。そのため、温度センサー５の出力によって電子制御装置６が電気発熱体３に通電して有機潜熱蓄熱材２の温度約８５−９５℃を保持する。そのため、１回の給湯動作の後にも、有機潜熱蓄熱材２が規定温度に達し保温状態になることで次回の給湯に備える。 By one hot water supply operation, the amount of heat of the organic latent heat storage material 2 in the tank 10 is taken away by the heat absorption pipe 4 through which cold water flows, and the temperature of the organic latent heat storage material 2 decreases. Therefore, the electronic control unit 6 energizes the electric heating element 3 by the output of the temperature sensor 5 to maintain the temperature of the organic latent heat storage material 2 at about 85-95 ° C. Therefore, even after one hot water supply operation, the organic latent heat storage material 2 reaches a specified temperature and is kept warm so that it is ready for the next hot water supply.
ここで、タンク１０、吸熱管４、電気発熱体３、有機潜熱蓄熱材２の位置関係と熱の流れについて説明する。タンク１０を透過した図１に示すように、電気発熱体３はタンク１０の略中心に配置している。そのため、電気発熱体３のタンク１０中心側はタング１０の中心側に存在する有機潜熱蓄熱材２を加熱する。また電気発熱体３のタンク１０側面１０ｃ側は、電気発熱体３と吸熱体４の間に存在する有機潜熱蓄熱材２を加熱する。タンク１０中心側の有機潜熱蓄熱材２は放熱部がない。また、電気発熱体３と吸熱体４の間に存在する有機潜熱蓄熱材２は吸熱体４へと放熱する。 Here, the positional relationship and heat flow of the tank 10, the heat absorption pipe 4, the electric heating element 3, and the organic latent heat storage material 2 will be described. As shown in FIG. 1 that has passed through the tank 10, the electric heating element 3 is disposed substantially at the center of the tank 10. Therefore, the tank 10 center side of the electric heating element 3 heats the organic latent heat storage material 2 existing on the center side of the tongue 10. Further, the tank 10 side surface 10 c side of the electric heating element 3 heats the organic latent heat storage material 2 existing between the electric heating element 3 and the heat absorbing element 4. The organic latent heat storage material 2 on the center side of the tank 10 does not have a heat radiating part. In addition, the organic latent heat storage material 2 existing between the electric heating element 3 and the heat absorber 4 radiates heat to the heat absorber 4.
さらに、吸熱体４の外側でタンク１０の側面１０ｃとの間に存在する有機潜熱蓄熱材２は、吸熱体４とタンク１０の側面１０ｃへと放熱する。タンク１０の側面１０ｃへの放熱を抑えるためにタンク１０には断熱材が設けられている。 Further, the organic latent heat storage material 2 existing between the outer side of the heat absorber 4 and the side surface 10 c of the tank 10 radiates heat to the heat absorber 4 and the side surface 10 c of the tank 10. In order to suppress heat radiation to the side surface 10c of the tank 10, the tank 10 is provided with a heat insulating material.
そのため、電気発熱体３の熱は、タンク１０の側面１０ｃに直接放熱して損失することなく、タンク１０の中心側の有機潜熱蓄熱材２と、吸熱体４の内側の有機潜熱蓄熱材２とに直接加熱する。よって、電気発熱体３を吸熱体の略中心に設けて熱量の損失を抑えることができる。 Therefore, the heat of the electric heating element 3 is not directly lost to the side surface 10c of the tank 10 and lost, but the organic latent heat storage material 2 on the center side of the tank 10 and the organic latent heat storage material 2 on the inner side of the heat absorption body 4 Heat directly to. Therefore, it is possible to suppress the loss of heat by providing the electric heating element 3 substantially at the center of the endothermic body.
また、本実施例ではタンク１０内で直接有機潜熱蓄熱材２を電気発熱体３で加熱して、有機潜熱蓄熱材２から吸熱管４を加熱して、熱した湯を溜める貯湯槽を不要とする構成にした。ここで、水１０Ｌ（Ｖ１＝１００００（ｃｍ3））を９５℃で保温した状態から３５℃に低下するまでの熱量Ｑ１を計算する。水の比重：１．０（ｇ／ ｃｍ3）、比熱：４．１８（Ｊ／ｇ・℃）として計算すると Ｑ１＝（９５℃−３５℃）×１００００（ｃｍ3）×１．０（ｇ／ ｃｍ3）×４．１８（Ｊ／ｇ・℃）＝２５０８（ｋＪ）となる。この計算から、熱した湯を溜める貯湯槽を備える構成の電気温水器では、水１０Ｌは２５０８（ｋＪ）の熱量Ｑ１を保持することが分かる。 Further, in this embodiment, the organic latent heat storage material 2 is directly heated by the electric heating element 3 in the tank 10, and the heat absorption pipe 4 is heated from the organic latent heat storage material 2, thereby eliminating the need for a hot water storage tank for storing hot water. It was configured to be. Here, calorie | heat amount Q1 until it falls to 35 degreeC from the state which kept water 10L (V1 = 10000 (cm < 3 >)) at 95 degreeC is calculated. When calculated as specific gravity of water: 1.0 (g / cm 3 ), specific heat: 4.18 (J / g · ° C.), Q1 = (95 ° C.-35 ° C.) × 10000 (cm 3 ) × 1.0 (g / Cm 3 ) × 4.18 (J / g · ° C.) = 2508 (kJ). From this calculation, it can be seen that in an electric water heater having a hot water storage tank for storing hot water, the water 10L holds a heat quantity Q1 of 2508 (kJ).
一方、本実施例の電気発熱体３で加熱して有機潜熱蓄熱材２から吸熱管４を加熱する構造で、有機潜熱蓄熱材２にポリエチレングリコールを用いた例で、前記と同じ水１０Ｌ（Ｖ１＝１００００（ｃｍ3））を９５℃で保温した状態から３５℃に低下する熱量を保持するタンク１０の容量Ｖ２を計算する。ポリエチレングリコールの比重：１．１９（ｇ／ｃｍ3）、比熱：２．３０（Ｊ／ｇ・℃）、融解熱：１９３（Ｊ／ｇ）、熱量Ｑ１＝２５０８（ｋＪ）とすると、Ｑ１（Ｊ）＝２５０８（ｋＪ）＝Ｖ２（ｃｍ3）×（９５℃−３５℃）×１．１９（ｇ／ｃｍ3）×２．３（Ｊ／ｇ・℃）＋Ｖ２（ｃｍ3）×１．１９（ｇ／ｃｍ3）×１９３（Ｊ／ｇ）が成立する。 On the other hand, in the example in which polyethylene glycol is used for the organic latent heat storage material 2 and heated by the electric heating element 3 of the present embodiment to heat the heat absorption tube 4 from the organic latent heat storage material 2, 10L (V1 = 10000 (cm 3 )) The volume V2 of the tank 10 that holds the amount of heat that decreases to 35 ° C from the state where the temperature is kept at 95 ° C is calculated. Specific gravity of polyethylene glycol: 1.19 (g / cm 3 ), specific heat: 2.30 (J / g · ° C.), heat of fusion: 193 (J / g), and calorie Q1 = 2508 (kJ), Q1 ( J) = 2508 (kJ) = V2 (cm 3 ) × (95 ° C.-35 ° C.) × 1.19 (g / cm 3 ) × 2.3 (J / g · ° C.) + V2 (cm 3 ) × 1. 19 (g / cm 3 ) × 193 (J / g) is established.
これより、Ｖ２＝２５０８×１０3／（（９５−３５）×１．１９×２．３＋１．１９×１９３））＝６３６７（ｃｍ3）となり、水１０Ｌの容積Ｖ１＝１００００（ｃｍ3）とタンク１０の容積Ｖ２＝６３６７（ｃｍ3）の比は Ｖ１：Ｖ２＝１００００：６３６７ となる。すなわち、タンク１０は、熱した湯を溜める貯湯槽を備える構成に比べて６４％の体積に小型化が可能となる。 Than this, V2 = 2508 × 10 3 /((95-35)×1.19×2.3+1.19×193))=6367(cm 3) , and the volume of water 10L V1 = 10000 and (cm 3) The ratio of the volume V2 = 6367 (cm 3 ) of the tank 10 is V1: V2 = 10000: 6367. That is, the tank 10 can be downsized to a volume of 64% as compared with a configuration including a hot water storage tank for storing hot water.
上記の本実施例によれば、蓄熱材は有機潜熱蓄熱材２で、吸熱管４は螺旋状に成形しタンク１０の略中心に垂直に設け、吸熱管４の上方に入口部４ｂと下方に出口部４ｄを設け、入口部４ｂはタンク１０の上面１０ａに出口部４ｄはタンク１０の下面１０ｂに固定し、電気発熱体３はＵ字状に成形し吸熱管４の螺旋の略中心に垂直に設け、タンク１０の下面１０ｂに端部３ａを固定するので電気発熱体３の内側は有機潜熱蓄熱材２を介してタンク１０の内部に熱が流れ、電気発熱体３の外側は有機潜熱蓄熱材２を介して吸熱管４に直接熱が流れるものである。 According to the above-described embodiment, the heat storage material is the organic latent heat storage material 2, the heat absorption tube 4 is formed in a spiral shape and provided perpendicularly to the substantial center of the tank 10, and the inlet portion 4 b is disposed below the heat absorption tube 4. An outlet portion 4 d is provided, the inlet portion 4 b is fixed to the upper surface 10 a of the tank 10, and the outlet portion 4 d is fixed to the lower surface 10 b of the tank 10. The electric heating element 3 is formed in a U shape and is perpendicular to the approximate center of the spiral of the heat absorption tube 4. Since the end portion 3a is fixed to the lower surface 10b of the tank 10, heat flows inside the electric heating element 3 through the organic latent heat storage material 2 inside the tank 10, and outside the electric heating element 3 is organic latent heat storage. Heat flows directly to the heat absorption tube 4 through the material 2.
よって、電気発熱体３からタンク１０の側面１０ｃへ熱量の損失がなく、電気発熱体３から有機潜熱蓄熱材２で吸熱管４を直接加熱する熱量が得られるので、タンク１０が小型となり電気温水器１の体積が小型にできる。 Therefore, there is no loss of heat from the electric heating element 3 to the side surface 10c of the tank 10, and the heat quantity directly heating the heat absorption tube 4 with the organic latent heat storage material 2 can be obtained from the electric heating element 3. The volume of the vessel 1 can be reduced.
有機潜熱蓄熱材２を使用することで貯湯槽が不要なため湯を貯湯する電気温水器に比べタンク１０その体積を約６４％に減らすことが可能となり電気温水器１の体積が小型にできる。 The use of the organic latent heat storage material 2 eliminates the need for a hot water storage tank, so the volume of the tank 10 can be reduced to about 64% compared to an electric water heater that stores hot water, and the volume of the electric water heater 1 can be reduced.
