Description
本発明は、貯湯式電気温水器に関し、特に、貯湯式電気温水器からの給湯流量を増大することができる貯湯式電気温水器に関するものである。 The present invention relates to a hot water storage type electric water heater, and more particularly to a hot water storage type electric water heater that can increase the flow rate of hot water supplied from the hot water storage type electric water heater.
一般的に、貯湯式電気温水器においては、その貯湯槽に、水道の直圧がかかる給水管が接続され、この給水管の圧力を利用して、貯湯槽に貯留されている湯を押し上げ、給湯を行うようにしている。 In general, in a hot water storage type electric water heater, a hot water tank is connected to the hot water tank, and the hot water stored in the hot water tank is pushed up using the pressure of the hot water pipe. I try to hot water.
ところで、従来、貯湯式電気温水器の貯湯槽に給水管を接続する場合、電気温水器の貯湯槽に水道の直圧がかからないようにするために、給水管の最上流側に減圧弁を配設し、この減圧弁を介して接続するようにしていた。 By the way, conventionally, when connecting a water supply pipe to a hot water storage tank of a hot water storage type electric water heater, a pressure reducing valve is arranged on the most upstream side of the water supply pipe to prevent direct water pressure from being applied to the hot water storage tank of the electric water heater. And connected via this pressure reducing valve.
しかしながら、このように、給水管の最上流側に減圧弁を配設して、貯湯式電気温水器の貯湯槽に給水管を接続するようにすると、貯湯式電気温水器の配管系の水圧が、減圧弁によって規制されることとなり、貯湯式電気温水器から供給される給湯流量を増大することが困難であるという問題があった。 However, if a pressure reducing valve is provided on the most upstream side of the water supply pipe and the water supply pipe is connected to the hot water storage tank of the hot water storage type electric water heater, the water pressure of the piping system of the hot water type electric water heater is reduced. Therefore, there is a problem that it is difficult to increase the flow rate of hot water supplied from the hot water storage type electric water heater.
本発明は、上記従来の貯湯式電気温水器機の有する問題点に鑑み、貯湯式電気温水器からの給湯流量を自由に増大することができる貯湯式電気温水器を提供することを目的とする。 An object of the present invention is to provide a hot water storage type electric water heater that can freely increase the flow rate of hot water supplied from the hot water storage type electric water heater in view of the problems of the conventional hot water storage type electric water heater.
上記目的を達成するため、本発明の貯湯式電気温水器は、温水を貯湯する貯湯槽を備えた貯湯式電気温水器において、水道の直圧がかかる給水管を分岐して、一方の分岐管を減圧弁を介して貯湯槽に接続し、前記給水管を分岐した他方の分岐管を、水道の直圧がかかった状態で、貯湯槽の湯と間接的に熱交換されて加熱される間接熱交換器に接続し、この間接熱交換器で加熱された直圧のかかった水道水と、前記間接熱交換器で加熱されていない直圧のかかった水道水とを合流させて給湯することを特徴とする。 To achieve the above object, a hot water storage type electric water heater of the present invention is a storage type electric water heater having a hot water storage tank for hot water storage hot water branches the water supply pipe take direct pressure of water, one branch pipe Is connected to a hot water storage tank through a pressure reducing valve, and the other branch pipe branched from the water supply pipe is heated indirectly by hot heat exchange with hot water in the hot water tank under direct pressure from the water supply. Connect to a heat exchanger and supply hot water by joining the direct pressure tap water heated by this indirect heat exchanger and the direct pressure tap water not heated by the indirect heat exchanger. It is characterized by.
この場合において、貯湯槽の上部に出湯管を接続し、貯湯槽内の湯を前記直圧のかかった給湯とは別系統で給湯するようにすることができる。 In this case, a hot water discharge pipe is connected to the upper part of the hot water storage tank, and the hot water in the hot water storage tank can be supplied by a separate system from the hot water supply with the direct pressure.
本発明の貯湯式電気温水器は、水道の直圧がかかる給水管を分岐して、一方の分岐管を減圧弁を介して貯湯槽に接続し、前記給水管を分岐した他方の分岐管を、水道の直圧がかかった状態で、貯湯槽の湯と間接的に熱交換されて加熱される間接熱交換器に接続し、この間接熱交換器で加熱された直圧のかかった水道水と、前記間接熱交換器で加熱されていない直圧のかかった水道水とを合流させて給湯することにより、貯湯槽に給水管から水道の直圧がかからないようにしながら、貯湯式電気温水器の配管系の水圧を高めることができ、貯湯式電気温水器からの給湯流量を自由に増大することができる。 The hot water storage type electric water heater of the present invention branches a water supply pipe to which direct water pressure is applied, connects one branch pipe to a hot water storage tank through a pressure reducing valve, and connects the other branch pipe branched from the water supply pipe. Connected to an indirect heat exchanger that is heated by indirectly exchanging heat with hot water in a hot water tank with direct water pressure applied, and the direct pressure tap water heated by this indirect heat exchanger And hot water storage type electric water heater while preventing the direct pressure of the water from being applied to the hot water tank from the water supply pipe by joining the hot water which is not heated by the indirect heat exchanger and applying the hot water The water pressure in the piping system can be increased, and the hot water flow rate from the hot water storage type electric water heater can be increased freely.
この場合において、貯湯槽の上部に出湯管を接続し、貯湯槽内の湯を前記直圧のかかった給湯とは別系統で給湯するようにすることにより、貯湯式電気温水器から高温の湯を供給することができる。 In this case, to connect the hot water pipe to the upper portion of the hot water tank, by the hot water took the hot water from the hot water storage tank of said linear pressure so as to hot water in a different system, the high temperature hot water storage type electric water heater water Can be supplied.
