Description

本発明は、減圧弁が備えられた温水供給装置に関する。より詳しくは、温水使用中に温水の温度偏差を最小化できる減圧弁が備えられた温水供給装置に関する。   The present invention relates to a hot water supply apparatus provided with a pressure reducing valve. More specifically, the present invention relates to a hot water supply device provided with a pressure reducing valve that can minimize temperature deviation of hot water during use of hot water.

一般的に、温水供給装置は、冷水を短時間で所定の温度に加熱して使用者が便利に温水を使用できるように構成された装置である。   Generally, the hot water supply device is a device configured to heat the cold water to a predetermined temperature in a short time so that the user can use the hot water conveniently.

図１は、従来の温水供給装置の構成を示す概略図である。   FIG. 1 is a schematic diagram showing a configuration of a conventional hot water supply apparatus.

従来の温水供給装置の構成を見ると、冷水流入管５を介して流入した冷水の流量を測定するための流量センサー１が備えられ、熱交換器８に流入した冷水は、送風機６から供給された空気とガスがバーナー７によって燃焼されて発生する燃焼熱との熱交換によって加熱されて温水供給管９を介して排出され、温水供給管９上には、温水の流量を調節するための流量調節弁４が備えられる。   Looking at the configuration of the conventional hot water supply device, a flow rate sensor 1 for measuring the flow rate of cold water flowing in through the cold water inflow pipe 5 is provided, and the cold water flowing into the heat exchanger 8 is supplied from the blower 6. The heated air and gas are heated by heat exchange with the combustion heat generated by the burner 7 and discharged through the hot water supply pipe 9. A flow rate for adjusting the flow rate of the hot water is provided on the hot water supply pipe 9. A control valve 4 is provided.

そして、冷水流入管５と温水供給管９との間には、流入した冷水を熱交換器８を経由せず、直接温水供給管９側に移送するバイパス管２が連結されており、熱交換器８を経て加熱された温水と冷水が混合されることにより、温水の温度を調節できるように構成される。   A bypass pipe 2 is connected between the cold water inflow pipe 5 and the hot water supply pipe 9 to transfer the cold water that has flowed in directly to the hot water supply pipe 9 without passing through the heat exchanger 8. The hot water and the cold water heated through the vessel 8 are mixed so that the temperature of the hot water can be adjusted.

そして、前記バイパス管２上には、ミキシングバルブ３が備えられて前記バイパス管２を介して移送される冷水の流量を調節することになる。   A mixing valve 3 is provided on the bypass pipe 2 to adjust the flow rate of the cold water transferred through the bypass pipe 2.

このような構成からなる温水供給装置１０を用いて温水を使用する途中に使用者が温水の使用流量を増加させると、冷水流入管５を介して流入する冷水の流量は、直ちに増加するのに対し、熱交換器８を経て温水供給管９に供給される温水の温度上昇は、相対的に遅くなって、使用者が設定した温度の温水を供給するまでに時間がかかる問題点がある。   If the user increases the flow rate of hot water while using the hot water supply device 10 having such a configuration, the flow rate of cold water flowing in through the cold water inflow pipe 5 immediately increases. On the other hand, the temperature rise of the hot water supplied to the hot water supply pipe 9 via the heat exchanger 8 becomes relatively slow, and there is a problem that it takes time to supply the hot water at the temperature set by the user.

逆に、使用者が温水を使用する途中に温水の使用流量を減少させると、冷水流入管５を介して流入する冷水の流量は、直ちに減少するのに対し、熱交換器８を経て温水供給管９に供給される温水の温度下落は、相対的に遅くなって、使用者が設定した温度の温水を供給するまでに時間がかかる問題点がある。   Conversely, if the user decreases the flow rate of hot water while using hot water, the flow rate of cold water flowing in via the cold water inflow pipe 5 immediately decreases, whereas hot water is supplied via the heat exchanger 8. The temperature drop of the hot water supplied to the pipe 9 is relatively slow, and there is a problem that it takes time to supply the hot water at the temperature set by the user.

これらの問題点を解決するために、バイパス管２にミキシングバルブ３を備え、冷水流入管１を介して流入する冷水の流量が変更されたことを流量センサー１で感知するようになると、制御部（図示せず）でミキシングバルブ３の開度を制御してバイパス管２を介して温水供給管９に混合される冷水の流量を調節することにより、使用者が設定した温度の温水を供給することになる。   In order to solve these problems, when the bypass pipe 2 is provided with the mixing valve 3 and the flow rate sensor 1 senses that the flow rate of the cold water flowing through the cold water inflow tube 1 is changed, By controlling the opening degree of the mixing valve 3 (not shown) and adjusting the flow rate of the cold water mixed into the hot water supply pipe 9 via the bypass pipe 2, hot water having a temperature set by the user is supplied. It will be.

しかし、ミキシングバルブ３は、その開度を調節するための構成が必要なためバルブの構造が複雑で、価格が高い問題点があり、ミキシングバルブ３を制御するためのシステム構成の費用が増加するという問題点があり、流量センサー１で流量を感知した後、ミキシングバルブ３の開度を調節するまでに時間がかかる問題点がある。   However, since the mixing valve 3 requires a configuration for adjusting the opening, the structure of the valve is complicated, and there is a problem that the price is high, and the cost of the system configuration for controlling the mixing valve 3 increases. There is a problem that it takes time until the opening degree of the mixing valve 3 is adjusted after the flow rate sensor 1 senses the flow rate.

前記のような従来技術の一例として、大韓民国登録特許第１０−１１７９８１２号「温水器の配管連結構造」が開示されている。   As an example of the prior art as described above, Korean Patent No. 10-1179812 “Piping connection structure of water heater” is disclosed.

本発明は、前述した様々の問題点を解決するために案出されたものであって、温水の使用流量が変更された場合にも、使用者に供給される温水の温度偏差を最小化できる減圧弁が備えられた温水供給装置を提供することにその目的がある。   The present invention has been devised to solve the various problems described above, and even when the flow rate of hot water used is changed, the temperature deviation of the hot water supplied to the user can be minimized. It is an object to provide a hot water supply device provided with a pressure reducing valve.

前記の目的を果たすための本発明の減圧弁が備えられた温水供給装置は、冷水が流入する冷水流入管と、バーナーの燃焼熱によって前記冷水流入管を介して流入した冷水を加熱する熱交換器と、前記熱交換器で加熱された温水を出水するための温水供給管と、前記冷水流入管と温水供給管との間を連結し、前記冷水流入管を介して流入した冷水の一部が前記温水供給管を介して出水される温水に混合されるように連結されたバイパス管と、前記バイパス管上に備えられ、温水供給時に前記バイパス管の内部を通過する水を減圧して前記温水供給管に供給する減圧弁からなる。   The hot water supply apparatus provided with the pressure reducing valve according to the present invention for achieving the above object includes a cold water inflow pipe into which cold water flows and heat exchange for heating the cold water flowing in through the cold water inflow pipe by the combustion heat of a burner. A portion of the cold water that flows in through the cold water inflow pipe, connecting the hot water supply pipe for discharging hot water heated by the heat exchanger, the cold water inflow pipe and the hot water supply pipe Is connected to the bypass pipe so as to be mixed with hot water discharged through the hot water supply pipe, and is provided on the bypass pipe to reduce the water passing through the bypass pipe when hot water is supplied. It consists of a pressure reducing valve that supplies the hot water supply pipe.

前記減圧弁は、前記冷水流入管に流入する冷水の流量が増加するにつれて、その内部を通過する水の流量が設定された流量まで増加した後、一定の流量で流れるように構成され得る。   The pressure reducing valve may be configured to flow at a constant flow rate after the flow rate of water passing through the inside increases to a set flow rate as the flow rate of the cold water flowing into the cold water inflow pipe increases.

前記減圧弁は、その内部に前記水が通過する冷水流路が形成され、前記冷水流路に供給される冷水の供給圧に応じて一定の形状に変形されることにより、前記冷水流路を通過する流量を制限するとともに、一定の流量で維持させる弾性部材が備えられ得る。   The pressure reducing valve has a cold water passage through which the water passes, and is deformed into a certain shape in accordance with a supply pressure of the cold water supplied to the cold water passage. An elastic member may be provided that restricts the flow rate passing therethrough and maintains the flow rate at a constant flow rate.

本発明の減圧弁が備えられた温水供給装置によると、バイパス管に減圧弁を備えることにより、別の制御装置を備えていなくても、簡単な構成で使用者の温水の使用流量の変更に対応し得、ミキシング率の変化が迅速に行われて温水の使用流量の変化に対応した応答性が速くなるため、温水の温度偏差を最小化できる。   According to the hot water supply device provided with the pressure reducing valve of the present invention, by providing the pressure reducing valve in the bypass pipe, the user can change the use flow rate of the hot water with a simple configuration without having another control device. It is possible to cope with this, and the change in the mixing rate is performed quickly, and the response corresponding to the change in the flow rate of the hot water is increased, so that the temperature deviation of the hot water can be minimized.

以下、添付された図面を参照しつつ、本発明による好ましい実施例を詳しく説明する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図２は、本発明の第１実施例による温水供給装置の構成を示す概略図である。   FIG. 2 is a schematic diagram showing the configuration of the hot water supply apparatus according to the first embodiment of the present invention.

本発明の第１実施例による温水供給装置１００は、温水器に減圧弁１３０が備えられたものであって、冷水が流入する冷水流入管１１１ａ、１１１ｂと、バーナー１５０の燃焼熱によって前記冷水流入管１１１ａ、１１１ｂを介して流入した冷水を加熱する熱交換器１４０と、前記熱交換器１４０で加熱された温水を出水するための温水供給管１１２ａ、１１２ｂと、前記冷水流入管１１１ａ、１１１ｂと温水供給管１１２ａ、１１２ｂとの間を連結して前記冷水流入管１１１ａを介して流入した冷水の一部が前記温水供給管１１２ｂを介して出水される温水に混合されるように連結されたバイパス管１１３と、前記バイパス管１１３上に備えられて温水供給時、前記バイパス管１１３の内部を通過する水を減圧して前記温水供給管１１２ｂに供給する減圧弁１３０と、を含んでなる。   The hot water supply device 100 according to the first embodiment of the present invention is provided with a pressure reducing valve 130 in a water heater, and the cold water inflow pipes 111a and 111b into which the cold water flows and the combustion heat of the burner 150 generate the cold water inflow. A heat exchanger 140 for heating the cold water flowing in through the tubes 111a and 111b, hot water supply pipes 112a and 112b for discharging the hot water heated by the heat exchanger 140, and the cold water inflow pipes 111a and 111b, A bypass connected between the hot water supply pipes 112a and 112b and connected so that a part of the cold water flowing in through the cold water inflow pipe 111a is mixed with the hot water discharged through the hot water supply pipe 112b. The hot water supply pipe 112b is provided on the bypass pipe 113 and the bypass pipe 113 to reduce the pressure of water passing through the bypass pipe 113 when hot water is supplied. A pressure reducing valve 130 is supplied, comprising.

前記冷水流入管１１１ａ上には、冷水の温度を測定するための冷水温度センサー１２１と、冷水の流量を測定するための流量センサー１２２が備えられる。   A cold water temperature sensor 121 for measuring the temperature of the cold water and a flow rate sensor 122 for measuring the flow rate of the cold water are provided on the cold water inlet pipe 111a.

前記温水供給管１１２ａ、１１２ｂ上には、熱交換器１４０で熱交換が行われて加熱された温水の温度を測定するための熱交換器温度センサー１２３と、バイパス管１１３を介して供給された冷水と温水が混合されて使用者に供給される温水の温度を測定するための温水温度センサー１２４が備えられる。   The hot water supply pipes 112a and 112b were supplied through a heat exchanger temperature sensor 123 for measuring the temperature of hot water heated by heat exchange in the heat exchanger 140 and a bypass pipe 113. A hot water temperature sensor 124 for measuring the temperature of the hot water supplied to the user by mixing the cold water and the hot water is provided.

前記バイパス管１１３は、温水供給管１１２ｂを介して供給される温水の温度を調節するために、冷水流入管１１１ａを介して流入した冷水の一部が温水供給管１１２ｂに供給されるように連結される。   The bypass pipe 113 is connected so that a part of the cold water flowing in through the cold water inflow pipe 111a is supplied to the hot water supply pipe 112b in order to adjust the temperature of the hot water supplied through the hot water supply pipe 112b. Is done.

前記減圧弁１３０は、前記バイパス管１１３を介して供給される冷水の流量を調節するためのもので、前記冷水流入管１１１ａから供給された冷水を減圧させて一定の流量の冷水が温水供給管１１２ｂに供給されるようにする。   The pressure reducing valve 130 is for adjusting the flow rate of the cold water supplied through the bypass pipe 113, and depressurizes the cold water supplied from the cold water inflow pipe 111a so that a constant flow of cold water is supplied to the hot water supply pipe. 112b.

使用者の温水の使用流量が変更された場合、一定の範囲までは温水の使用流量が増加するにつれて、減圧弁１３０の内部を通過する冷水の流量が増加するようになっているが、温水の使用流量が一定の範囲を超過する場合には、温水の使用流量が増加しても減圧弁１３０の内部を通過する冷水の流量が一定に維持される。   When the user's use flow rate of hot water is changed, the flow rate of cold water passing through the pressure reducing valve 130 increases as the use flow rate of hot water increases up to a certain range. When the usage flow rate exceeds a certain range, the flow rate of cold water passing through the pressure reducing valve 130 is kept constant even if the usage flow rate of hot water increases.

このように減圧弁１３０を通過する冷水の流量は、所定の流量だけ増加した後に一定の流量を維持するのに対し、前記減圧弁１３０を通過する流量を除いた残りの流量は、熱交換器１４０に供給される。このため、温水の使用流量が変更されると、それに応じて前記熱交換器１４０に供給される流量は、温水の使用流量の変更とともに変更されて、前記熱交換器１４０で加熱されて温水供給管１１２ａに供給される温水と前記減圧弁１３０を通過する冷水の流量の割合であるミキシング率は、温水の使用流量が変更されるのに応じて一緒に変更されることにより、温水の温度偏差が最小化される。   As described above, the flow rate of the cold water passing through the pressure reducing valve 130 is maintained at a constant flow rate after being increased by a predetermined flow rate, whereas the remaining flow rate excluding the flow rate passing through the pressure reducing valve 130 is the heat exchanger. 140. For this reason, when the use flow rate of the hot water is changed, the flow rate supplied to the heat exchanger 140 is changed along with the change of the use flow rate of the hot water and heated by the heat exchanger 140 to supply the hot water. The mixing rate, which is a ratio of the flow rate of the hot water supplied to the pipe 112a and the cold water passing through the pressure reducing valve 130, is changed together according to the change in the use flow rate of the hot water. Is minimized.

このような減圧弁１３０は、その構造が非常に簡単で、冷水の供給圧に応じて自動的にミキシング率を変化させるため、システム全体の構成を非常に簡単に具現し得る。   Since the pressure reducing valve 130 has a very simple structure and automatically changes the mixing rate in accordance with the supply pressure of the cold water, the configuration of the entire system can be realized very easily.

図３は、本発明の一実施例による減圧弁の内部構造を示す断面図であり、図４は、図３の減圧弁で冷水の供給圧の変化に応じて弾性部材が変形された状態を示す断面図であって、以下図３ないし図４を参照して本発明の一実施例による減圧弁の構成及び作用について説明する。   3 is a cross-sectional view illustrating an internal structure of a pressure reducing valve according to an embodiment of the present invention. FIG. 4 illustrates a state in which the elastic member is deformed according to a change in the supply pressure of cold water in the pressure reducing valve of FIG. The configuration and operation of a pressure reducing valve according to an embodiment of the present invention will be described below with reference to FIGS.

減圧弁１３０は、射出成形によって一体に形成されたバルブボディ１３１と、前記バルブボディ１３１の内側に挟まれて冷水の供給圧に応じて変形されることにより、冷水の流路を制限する弾性部材１３４で構成される。   The pressure reducing valve 130 includes a valve body 131 integrally formed by injection molding, and an elastic member that restricts the flow path of cold water by being sandwiched between the valve body 131 and being deformed according to the supply pressure of the cold water. 134.

前記バルブボディ１３１は、冷水の流路が内部に形成された円筒部材１３２と、前記円筒部材１３２の内側中央部に備えられる中央柱部材１３３からなる。   The valve body 131 includes a cylindrical member 132 in which a flow path of cold water is formed, and a central column member 133 provided at an inner central portion of the cylindrical member 132.

前記弾性部材１３４は、円筒部材１３２の内側面と中央柱部材１３３の外側面との間に挿入され、冷水の流入時に前記弾性部材１３４は、圧縮されて図４のように左右方向に膨張することにより、冷水が通過する流路の断面積を変化させる。   The elastic member 134 is inserted between the inner surface of the cylindrical member 132 and the outer surface of the central column member 133. When the cold water flows in, the elastic member 134 is compressed and expands in the left-right direction as shown in FIG. Thus, the cross-sectional area of the flow path through which the cold water passes is changed.

冷水の流れを誘導するための構成として、前記円筒部材１３２の内側面には、円周方向に沿って一定の間隔で突出したガイドリブ１３２ａが形成され、隣接するガイドリブ１３２ａどうしの間にはガイド溝１３２ｂが形成される。   As a configuration for guiding the flow of cold water, guide ribs 132a projecting at a constant interval along the circumferential direction are formed on the inner surface of the cylindrical member 132, and guide grooves are formed between adjacent guide ribs 132a. 132b is formed.

前記ガイドリブ１３２ａの上端部には、前記中央柱部材１３３の中心軸に向かって一定の長さで突出した突出片１３２ｃが形成され、前記ガイド溝１３２ｂの上端部にも、前記中央柱部材１３３に向かって一定の長さで突出した突出片１３２ｄが形成される。
前記ガイドリブ１３２ａから延長された突出片１３２ｃと隣接する前記ガイド溝１３２ｂから延長された突出片１３２ｄとの間には、上下方向に段差が交差するように形成されて冷水が通過する流路である冷水通過ホール１３５を形成することになる。 A protruding piece 132c is formed at the upper end portion of the guide rib 132a so as to protrude toward the central axis of the central column member 133 with a certain length. The upper end portion of the guide groove 132b is also formed on the central column member 133. A protruding piece 132d that protrudes at a constant length is formed.
Between the protruding piece 132c extended from the guide rib 132a and the protruding piece 132d extended from the adjacent guide groove 132b, a flow path is formed so that a step is intersected in the vertical direction and cold water passes therethrough. A cold water passage hole 135 is formed.

冷水の供給圧が一定の圧力以下の低圧状態では、図３に示すように弾性部材１３４は、その断面が円形に近い形状を維持することになるため、冷水が流れる流路は、弾性部材１３４と中央柱部材１３３の外側面の間の空間及び弾性部材１３４と円筒部材１３２の内側面の間の空間に広く形成されて、流入する冷水はそのまま通過することになる。   In the low pressure state where the supply pressure of the chilled water is equal to or lower than a certain pressure, the elastic member 134 maintains a cross-sectional shape close to a circular shape as shown in FIG. And the space between the outer side surfaces of the central column member 133 and the space between the elastic member 134 and the inner side surface of the cylindrical member 132, the inflowing cold water passes through as it is.

これに反して、冷水の圧力が高くなると、図４に示すように冷水の供給圧に応じて、弾性部材１３４は、その形状が平たい楕円形状に変形されて、冷水が流れる流路は、弾性部材１３４と中央柱部材１３３の外側面の間の空間に制限されて流路が狭く形成されるため、流入する冷水の通過流量が一定量の以下に制限される。   On the other hand, when the pressure of the cold water increases, the elastic member 134 is deformed into a flat oval shape according to the cold water supply pressure as shown in FIG. Since the flow path is narrowed by being limited to the space between the member 134 and the outer surface of the central column member 133, the flow rate of the flowing cold water is limited to a certain amount or less.

この場合、弾性部材１３４は、一定の範囲まで変形され、冷水の供給圧力がそれ以上高くなっても、断面形状の変化は起こらないため、冷水の通過流量が一定に維持される。   In this case, the elastic member 134 is deformed to a certain range, and even if the supply pressure of the cold water is further increased, the cross-sectional shape does not change, so the flow rate of the cold water is kept constant.

図５は、本発明の温水供給装置で冷水の供給圧に応じた流量の変化を示すグラフであり、図６は、本発明の温水供給装置で流量の変化に応じた温水の温度変化を示すグラフであり、下記の表１は、各配管を通過する流量とミキシング率を示す表であり、下記の表２は、流量と温度及びミキシング率の関係を示す表である。   FIG. 5 is a graph showing a change in flow rate according to the supply pressure of cold water in the hot water supply device of the present invention, and FIG. 6 shows a temperature change of hot water according to the change in flow rate in the hot water supply device of the present invention. It is a graph and the following Table 1 is a table | surface which shows the flow volume and mixing rate which pass each piping, and the following Table 2 is a table | surface which shows the relationship between a flow volume, temperature, and a mixing rate.

図５と表１において、ミキシング流量とは、冷水流入管１１１ａを介して流入した冷水中でバイパス管１１３を経て温水供給管１１２ａ、１１２ｂに供給されて温水供給管１１２ａを流動する温水と混合される冷水の流量を意味し、熱交換器流量とは、熱交換器１４０で加熱された後、温水供給管１１２ａに供給される温水の流量を意味し、全体流量とは、ミキシング流量と熱交換器流量を合わせた流量であって冷水流入管１１１ａを介して流入する冷水の流量と同じであり、ミキシング率とは、全体流量中でミキシング流量が占める割合を意味する。   5 and Table 1, the mixing flow rate is mixed with the hot water flowing through the hot water supply pipe 112a by being supplied to the hot water supply pipes 112a and 112b through the bypass pipe 113 in the cold water flowing in via the cold water inflow pipe 111a. The heat exchanger flow rate means the flow rate of warm water supplied to the hot water supply pipe 112a after being heated by the heat exchanger 140, and the total flow rate is the mixing flow rate and heat exchange. The mixing flow rate is the same as the flow rate of cold water flowing in via the cold water inflow pipe 111a, and the mixing rate means the ratio of the mixing flow rate to the total flow rate.

図６と表２において、熱交換器温度は、熱交換器温度センサー１２３で測定された温水の温度を意味し、温水温度は、温水温度センサー１２４で測定された温水の温度を意味し、冷水温度は、冷水温度センサー１２１で測定された冷水の温度を意味する。   6 and Table 2, the heat exchanger temperature means the temperature of hot water measured by the heat exchanger temperature sensor 123, and the hot water temperature means the temperature of hot water measured by the hot water temperature sensor 124. The temperature means the temperature of the cold water measured by the cold water temperature sensor 121.

全体流量が３から１４まで変化する場合、３から４に変わる区間では、ミキシング流量が全体流量の増加とともに増加するが、４から１４まで変わる区間では、減圧弁１３０の弾性部材１３４が図４のように圧縮された後、それ以上変わらないため、全体流量が増加してもミキシング流量は、一定に維持される。   When the total flow rate changes from 3 to 14, the mixing flow rate increases as the total flow rate increases in the interval from 3 to 4, but in the interval from 4 to 14, the elastic member 134 of the pressure reducing valve 130 is shown in FIG. After the compression, the mixing flow rate is kept constant even if the total flow rate is increased.

これに反して、熱交換器流量は、全体流量が増加するにつれて、一緒に増加することになるため、ミキシング率は、全体流量が増加するにつれて、減少することになる。   On the other hand, since the heat exchanger flow rate will increase together as the overall flow rate increases, the mixing rate will decrease as the overall flow rate increases.

この場合、冷水温度は、２０度で一定する一方、熱交換器温度は、熱交換器１４０に供給される冷水の流量が増加するにつれて、６１．５度から４８度に下落することになる。   In this case, the cold water temperature is constant at 20 degrees, while the heat exchanger temperature falls from 61.5 degrees to 48 degrees as the flow rate of the cold water supplied to the heat exchanger 140 increases.

したがって、使用者が温水の使用流量を増加させて、全体流量が３から１４に増加してもミキシング率が０．４から０．１１に減少するため、温水供給管１１２ｂを介して使用者に供給される温水温度は、４５度で一定に維持し得る。   Therefore, even if the user increases the use flow rate of the hot water and the total flow rate increases from 3 to 14, the mixing rate decreases from 0.4 to 0.11, so that the user is notified via the hot water supply pipe 112b. The supplied hot water temperature can be kept constant at 45 degrees.

逆に、使用者が温水の使用流量を減少させて、全体流量が１４から３に減少してもミキシング率が０．１１から０．４に増加するため、温水温度は、４５度で一定に維持し得る。   Conversely, if the user decreases the hot water flow rate and the total flow rate decreases from 14 to 3, the mixing rate increases from 0.11 to 0.4, so the hot water temperature remains constant at 45 degrees. Can be maintained.

このように、バイパス管１１３に減圧弁１３０を設置すると、使用者の温水の使用流量が変更されても減圧弁１３０の流量が自然に一定に制限されることにより、ミキシング率が変化するようになるため使用者に供給される温水の温度は、均一に維持し得る。
したがって、従来のようにミキシングバルブの開度を調節するような制御を必要としないため、装置の構成が簡単になり、使用者の温水の使用流量の変化と同時に減圧弁１３０の流量が制限されるため、迅速な応答性によって温水の温度偏差を最小化できる。 As described above, when the pressure reducing valve 130 is installed in the bypass pipe 113, the mixing rate changes so that the flow rate of the pressure reducing valve 130 is naturally limited to a constant even if the flow rate of the warm water of the user is changed. Therefore, the temperature of the hot water supplied to the user can be kept uniform.
Therefore, since the control for adjusting the opening of the mixing valve is not required as in the prior art, the configuration of the apparatus is simplified, and the flow rate of the pressure reducing valve 130 is limited simultaneously with the change in the user's hot water usage flow rate. Therefore, the temperature deviation of hot water can be minimized by quick response.

図７は、本発明の第２実施例による温水供給装置の構成を示す概略図である。   FIG. 7 is a schematic view showing a configuration of a hot water supply device according to a second embodiment of the present invention.

第１実施例は、減圧弁１３０が温水器に適用された場合を示す一方、第２実施例による温水供給装置２００は、ボイラーに減圧弁２３０が適用された場合を示す。   The first embodiment shows a case where the pressure reducing valve 130 is applied to a water heater, while the hot water supply device 200 according to the second embodiment shows a case where the pressure reducing valve 230 is applied to a boiler.

A water pipe 215, a circulation pump 270 provided on the heating return water pipe 215, a heating supply pipe 214 and the heating return water pipe 215 are connected to each other and connected to a three-way valve 272 to supply heating water to the hot water supply heat exchanger 240. The boiler has the same configuration as that of the boiler including the heated water supply pipe 216 for hot water supply and capable of heating and supplying hot water.

温水を供給するための構成であって、冷水流入管２１１、冷水温度センサー２２１、流量センサー２２２、熱交換器温度センサー２２３、温水供給管２１２、温水温度センサー２２４、バイパス管２１３、減圧弁２３０は、第１実施例と同一の構成からなる。   A configuration for supplying hot water, the cold water inflow pipe 211, the cold water temperature sensor 221, the flow sensor 222, the heat exchanger temperature sensor 223, the hot water supply pipe 212, the hot water temperature sensor 224, the bypass pipe 213, and the pressure reducing valve 230 are The configuration is the same as that of the first embodiment.

[変形実施例]

It is possible to modify the structure.

例えば、冷水が通過する流路を遮断するバルブ部がスプリングによって弾性支持され、冷水の圧力に応じてスプリングの弾性力を調節し、バルブ部の開放の程度が変わるようにすることで減圧弁の機能を具現し得る。   For example, a valve portion that blocks a flow path through which cold water passes is elastically supported by a spring, and the elastic force of the spring is adjusted in accordance with the pressure of the cold water so that the degree of opening of the valve portion changes, so that the pressure reducing valve Functions can be implemented.
