【0001】[0001]
本考案は、給湯使用直後、熱交換器内のいわゆる" 後沸き" 現象による湯の膨 張によって発生する膨張水を、配管外への漏れを生じることなく吸収できる給湯 装置に関する。 The present invention relates to a hot water supply device that can absorb expanded water generated by expansion of hot water due to a so-called "post-boiling" phenomenon in a heat exchanger immediately after hot water supply without leaking to the outside of piping.

従来、給湯機の一形態として図4に示す1缶2回路式給湯機Aがある。 Conventionally, there is a one-can, two-circuit water heater A shown in FIG. 4 as one form of a water heater.
【0003】 図中、50は1缶2回路式給湯機Aの缶体であり、同缶体50は、並設した多数の フィン51を共用し、このフィン51の上部に複数の風呂用吸熱管52を、下部に複数 の給湯用吸熱管53を取付けている。In the figure, 50 is a can body of a one-can / two-circuit water heater A. The can body 50 shares a large number of fins 51 arranged in parallel, and a plurality of heat-absorbing baths are provided above the fins 51. A pipe 52 and a plurality of hot water supply heat absorption pipes 53 are attached to the lower part.
【0004】 また、缶体50の下部には、同缶体50を加熱するバーナ54が配設されており、同 バーナ54への燃料供給路55には、電磁弁56と比例弁57とが取付けられている。Further, a burner 54 for heating the can body 50 is disposed below the can body 50, and a solenoid valve 56 and a proportional valve 57 are provided in a fuel supply passage 55 to the burner 54. Installed.
【0005】 さらに、風呂用吸熱管52は、中途に循環ポンプ58を取付けた循環流路59を介し て浴槽60に連通連結されている。Further, the bath heat absorption tube 52 is connected to a bath 60 through a circulation flow path 59 having a circulation pump 58 attached midway.
【0006】 一方、給湯用吸熱管53の水流入口には給水配管61が接続されており、出湯口に は給湯配管62が接続されている。On the other hand, a water supply pipe 61 is connected to the water inlet of the hot water supply endothermic pipe 53, and a hot water supply pipe 62 is connected to the hot water outlet.
【0007】 かかる構成を有する1缶2回路式給湯機Aは、バーナ14の燃焼によって、単一 の缶体50を用いて、浴槽60の追焚を行うことができるのみならず、台所等におけ る水栓63へ給湯配管62を通して出湯することができる。The one-can two-circuit water heater A having such a configuration can not only reheat the bathtub 60 by using the single can body 50 by burning the burner 14, but also in a kitchen or the like. Hot water can be discharged to the faucet 63 through the hot water supply pipe 62.
【0008】 また、かかる1缶2回路式給湯機Aは、給水配管61に逆止弁64を設けるととも に、給湯配管62に過圧逃がし弁64を設けている。In addition, the one-can, two-circuit water heater A is provided with a check valve 64 in the water supply pipe 61 and an overpressure relief valve 64 in the hot water supply pipe 62.
【0009】 かかる構成によって、給湯使用直後に、熱交換器内の湯がいわゆる" 後沸き" 現象を起こし、湯の膨張を発生した場合、給水配管61には過圧逃がし弁64が取付 けられているため、給湯配管62内の圧力が上昇し、同配管62内の圧力が設定圧、 例えば、10 kgf/cm2を越えると、過圧逃がし弁64より膨張水又は膨張湯が外部に 漏れることになる。With such a structure, when hot water in the heat exchanger causes a so-called “post-boiling” phenomenon immediately after hot water supply is used and expansion of the hot water occurs, an overpressure relief valve 64 is attached to the water supply pipe 61. Therefore, when the pressure in the hot water supply pipe 62 rises and the pressure in the hot water supply pipe 62 exceeds the set pressure, for example, 10 kgf / cm 2 , the overpressure relief valve 64 causes the expansion water or the expansion water to leak to the outside. It will be.
【0010】[0010]
しかし、過圧逃がし弁64より膨張水又は膨張湯の外部への漏れは、以下の問題 を有していた。 However, leakage of the expanded water or the expanded hot water from the overpressure relief valve 64 to the outside had the following problems.
【0011】 給湯機の設置場所がパイプシャフト内 (扉内、排延、FF系) では、排水設備 がなければたれ流しになる。If the location of the water heater is inside the pipe shaft (inside the door, the outlet, the FF system), if there is no drainage facility, it will fall down.
【0012】 仮に排水設備がある場合は、排水手段を講じる必要がある。If there is a drainage facility, it is necessary to devise a drainage means.
【0013】 膨張水が漏れると、量にもよるがロスが大きい。If the expansion water leaks, the loss is large, depending on the amount.
【0014】 本考案は、上記した課題を解決することができる1缶2回路式風呂釜を提供す ることを目的とする。An object of the present invention is to provide a one-can, two-circuit bathtub that can solve the above problems.
【0015】[0015]

【0021】[0021]
以下、添付図に示す実施例を参照して、本考案を具体的に説明する。 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.
【0022】 図1において、10は1缶2回路式給湯機Aの缶体であり、同缶体10は、並設し た多数のフィン11を共用し、このフィン11の上部に複数の風呂用吸熱管12を、下 部に複数の給湯用吸熱管13を取付けている。In FIG. 1, reference numeral 10 denotes a can body of a 1-can 2-circuit type water heater A. The can body 10 shares a large number of fins 11 arranged in parallel, and a plurality of baths are provided above the fins 11. The heat absorbing tube 12 for water is attached, and a plurality of heat absorbing tubes 13 for hot water supply are attached to the lower part.
【0023】 また、缶体10の下部には、同缶体10を加熱するバーナ14が配設されており、同 バーナ14への燃料供給路15には、電磁弁16と比例弁17とが取付けられている。A burner 14 for heating the can body 10 is disposed below the can body 10, and a solenoid valve 16 and a proportional valve 17 are provided in a fuel supply path 15 to the burner 14. Installed.
【0024】 さらに、風呂用吸熱管12は、中途に循環ポンプ20を取付けた循環流路21を介し て浴槽22に連通連結されている。Further, the bath heat absorption tube 12 is connected to a bath 22 through a circulation flow passage 21 having a circulation pump 20 attached midway.
【0025】 一方、給湯用吸熱管13の水流入口23には給水配管24が接続されており、出湯口 25には給湯配管26が接続されている。On the other hand, a water supply pipe 24 is connected to the water inlet 23 of the hot water supply endothermic pipe 13, and a hot water supply pipe 26 is connected to the hot water outlet 25.
【0026】 かかる構成を有する1缶2回路式給湯機Aは、バーナ14の燃焼によって、単一 の缶体10を用いて、浴槽22の追焚を行うことができるのみならず、台所等におけ る水栓27へ給湯配管26を通して出湯することができる。The one-can, two-circuit water heater A having such a configuration can not only reheat the bathtub 22 by using the single can body 10 by burning the burner 14, but also for a kitchen or the like. Hot water can be discharged to the faucet 27 through the hot water supply pipe 26.
【0027】 本考案は、上記した構成を有する1缶2回路式給湯機Aにおいて、給湯使用直 後に、熱交換器内の湯がいわゆる" 後沸き" 現象を起こして生ずる膨張水を、以 下に詳述する逆止弁付圧力逃がし弁Bによって、外部等に洩らすことなく処理す ることができる給湯装置の構成にある。According to the present invention, in the one-can two-circuit water heater A having the above-described structure, the expansion water generated by the so-called "post-boiling" phenomenon of the hot water in the heat exchanger immediately after the hot water is used is described below. With the pressure relief valve B with a check valve, which will be described in detail below, the hot water supply device can be processed without leakage to the outside or the like.
【0028】 即ち、図1に示すように、逆止弁付圧力逃がし弁Bは、給水配管24の中途に設 けられている。That is, as shown in FIG. 1, the pressure relief valve B with a check valve is provided in the middle of the water supply pipe 24.
【0029】 図2及び図3を参照して説明すると、逆止弁付圧力逃がし弁Bは、弁ブロック 30内に、実質的に、逆止弁Cと圧力逃がし弁Dとを一体的に組み込んだことを特 徴とする。Referring to FIG. 2 and FIG. 3, the pressure relief valve B with a check valve substantially integrates the check valve C and the pressure relief valve D in the valve block 30. That is the feature.
【0030】 まず、逆止弁Cの構成について説明すると、弁ブロック30は、その内部に上流 側流路31と、下流側流路32と、両流路31,32 を直交状態に連絡する弁座形成流路 33とからなる屈曲流路を形成している。First, the structure of the check valve C will be described. The valve block 30 includes a valve for connecting the upstream side flow passage 31, the downstream side flow passage 32, and the both flow passages 31, 32 in an orthogonal state. A bent flow path including the seat forming flow path 33 is formed.
【0031】 そして、弁座形成流路33内には、先端に弁座34を形成するとともに基端を閉塞 した筒状スリーブ35が嵌入されている。A tubular sleeve 35 having a valve seat 34 formed at the tip and a closed base end is fitted into the valve seat forming flow path 33.
【0032】 弁座30の下流側面には逆止弁体36が当接しており、同逆止弁体36は、スリーブ 35内の内部空間37に配設した引張バネ38によって閉弁方向に常時付勢されている 。A check valve body 36 is in contact with the downstream side surface of the valve seat 30, and the check valve body 36 is always closed in the valve closing direction by a tension spring 38 arranged in an internal space 37 in the sleeve 35. Being energized.
【0033】 また、スリーブ35の一側側壁には、スリーブ35の内部空間37と上流側流路31と を連通する連通開口39が設けられている。A communication opening 39 that communicates the internal space 37 of the sleeve 35 and the upstream flow path 31 is provided on one side wall of the sleeve 35.
【0034】 一方、スリーブ35の他側側壁には、後述する圧力逃がし弁Dの圧力逃がし室41 とスリーブ35の内部空間37とを連通させるための連通開口40が設けられている。On the other hand, the other side wall of the sleeve 35 is provided with a communication opening 40 for communicating a pressure relief chamber 41 of the pressure relief valve D, which will be described later, with the internal space 37 of the sleeve 35.
【0035】 かかる構成によって、通常給水時には、給水圧がバネ圧より高いので、逆止弁 体36を進出して逆止弁Cを開弁し、給湯用吸熱管13に給水することができる。With such a configuration, since the water supply pressure is higher than the spring pressure during normal water supply, it is possible to advance the check valve body 36 to open the check valve C and supply water to the hot water heat absorption pipe 13.
【0036】 また、熱交換器内の湯がいわゆる" 後沸き" 現象を起こして膨張水が生じた場 合は、膨張水が、下流側流路32→弁座形成流路33→上流側流路31を通して逆止す るのを防止することができる。When the hot water in the heat exchanger causes a so-called “post-boiling” phenomenon to generate expanded water, the expanded water flows from the downstream side flow passage 32 to the valve seat forming flow passage 33 to the upstream side flow. It is possible to prevent a reverse check through the path 31.
【0037】 次に圧力逃がし弁Dの構成について説明すると、上記した逆止弁Cの弁座形成 流路32と並設状態に、弁ブロック30内に圧力逃がし室41が形成されている。Next, the structure of the pressure relief valve D will be described. A pressure relief chamber 41 is formed in the valve block 30 in parallel with the valve seat forming flow path 32 of the check valve C described above.
【0038】 この圧力逃がし室41内には、弁体42が進退自在にかつ水密状態に配設されてお り、同弁体42の一側には膨張水流入室43が形成されるとともに、他側には浄水流 入室44が形成されており、両室43,44 間の連通は完全に遮断されている。In the pressure relief chamber 41, a valve body 42 is arranged so as to be able to move back and forth and in a watertight state, and an expansion water inflow chamber 43 is formed on one side of the valve body 42 and A clean water inlet chamber 44 is formed on the side, and the communication between the two chambers 43 and 44 is completely cut off.
【0039】 膨張水流入室43は、隔壁45に設けた小孔46を通して、上流側流路31と連通して いる。The expansion water inflow chamber 43 communicates with the upstream flow path 31 through a small hole 46 provided in the partition wall 45.
【0040】 一方、同浄水流入室44は、側壁47に設けた小孔48及び上述した連通開口40を通 して、逆止弁C内の内部空間37と連通している。On the other hand, the purified water inflow chamber 44 communicates with the internal space 37 in the check valve C through the small hole 48 provided in the side wall 47 and the communication opening 40 described above.
【0041】 さらに、浄水流入室44内には、常時、弁体42を、膨張水流入室43に向けて付勢 する弾性手段としての圧縮バネ49が配設されている。Further, in the purified water inflow chamber 44, a compression spring 49 as an elastic means for constantly urging the valve body 42 toward the expansion water inflow chamber 43 is provided.
【0042】 この圧縮バネ49の付勢力ないし抗圧力は、給水源の断水等によって発生する負 圧以上とする。The urging force or coercive pressure of the compression spring 49 is set to be equal to or higher than the negative pressure generated by the water supply source being cut off.
【0043】 なお、図2におけるその他の構成について説明すると、5は圧力逃がし室41の 基端側を閉塞する栓体、6はスリーブ35を保持する栓体、7は給湯装置Aの壁部 、8は壁部51から外部に突出した給水接続口である。2 will be described. 5 is a plug for closing the base end side of the pressure relief chamber 41, 6 is a plug for holding the sleeve 35, 7 is a wall of the water heater A, Reference numeral 8 is a water supply connection port that protrudes from the wall portion 51 to the outside.
【0044】 かかる構成によって、常時は、圧縮バネ49は、弁体42を側壁45に押圧して、下 流側流路32からの水又は湯が、小孔46を通して圧力逃がし室41内に流入するのを 防止することができる。With such a configuration, the compression spring 49 normally presses the valve body 42 against the side wall 45 so that water or hot water from the downstream flow passage 32 flows into the pressure relief chamber 41 through the small hole 46. Can be prevented.
【0045】 また、熱交換器内の湯がいわゆる" 後沸き" 現象を起こして膨張水が生じた場 合は、膨張水の膨張圧は上記した圧縮バネ49の抗圧力より大きくなるので、膨張 水を下流側流路32→小孔46を通して圧力逃がし室41の膨張水流入室43内に流入さ せることができ、膨張水の吸収を図ることができる。When the hot water in the heat exchanger undergoes the so-called “post-boiling” phenomenon to generate expanded water, the expansion pressure of the expanded water becomes larger than the coercive pressure of the compression spring 49 described above. Water can be made to flow into the expansion water inflow chamber 43 of the pressure relief chamber 41 through the downstream side flow path 32 → small hole 46, and absorption of the expansion water can be achieved.
【0046】 この際、圧力逃がし室41の浄水流入室44と逆止弁Cの筒状スリーブ35内の内部 空間37とは連通しているので、弁体42は速やかに右側に移動し、圧力逃がし弁D の円滑な作動が保障されるとともに、配管外に膨張水が漏れるのを確実に防止す ることができる。At this time, since the purified water inflow chamber 44 of the pressure relief chamber 41 and the internal space 37 in the tubular sleeve 35 of the check valve C communicate with each other, the valve body 42 quickly moves to the right side, The smooth operation of the relief valve D is ensured, and the expansion water can be reliably prevented from leaking outside the pipe.
【0047】 次に、上記構成を有する逆止弁付圧力逃がし弁Bの作動について説明する。Next, the operation of the pressure relief valve B with a check valve having the above configuration will be described.
【0048】 給湯直後の缶体10周り給湯用吸熱管13内の湯がいわゆる" 後沸き" 現象により 膨張すると、圧力は伝播するので、給水側から給湯側にかけて均一にかかる。こ の時、逆止弁Cは逆流を防止するために閉となるが、圧力逃がし弁Dは圧力が一 定値以上になった場合開となり、弁体42が図2において右方向に移動して膨張水 流入室43は充分な容積を確保でき、膨張分を吸収する。When the hot water in the heat-absorbing tube 13 around the can body 10 immediately after hot water supply expands due to the so-called "post-boiling" phenomenon, the pressure propagates, and the pressure is evenly applied from the water supply side to the hot water supply side. At this time, the check valve C is closed to prevent backflow, but the pressure relief valve D is opened when the pressure exceeds a certain value, and the valve element 42 moves to the right in FIG. The expansion water inflow chamber 43 can secure a sufficient volume and absorbs the expansion.
【0049】 この際、浄水流入室44内の浄水の一部が、小孔48を通して、逆止弁C内の内部 空間37に流入するので、上記した弁体42の移動を速やかに行うことができる。At this time, a part of the purified water in the purified water inflow chamber 44 flows into the internal space 37 in the check valve C through the small hole 48, so that the above-described movement of the valve body 42 can be performed quickly. it can.
【0050】 また、膨張水流入室43と浄水流入室44との連通は弁体42によって水密状態に遮 断されているので、膨張した水が膨張水流入室43から浄水流入室44を通して給水 側に流れ込み、混合するのを確実に防止することができる。Further, since the communication between the expanded water inflow chamber 43 and the purified water inflow chamber 44 is blocked in a watertight state by the valve body 42, the expanded water flows from the expanded water inflow chamber 43 through the purified water inflow chamber 44 to the water supply side. Therefore, it is possible to surely prevent the mixture.
【0051】 このように、本実施例では、膨張水は圧力逃がし弁D内に保留され外部に漏出 することがないので、別途高価な排水手段を設けることが不要となり、給湯装置 Aを安価に製作することができる。As described above, in this embodiment, the expanded water is retained in the pressure relief valve D and does not leak to the outside. Therefore, it is not necessary to provide an expensive drainage means separately, and the hot water supply device A can be inexpensively manufactured. Can be manufactured.
【0052】 また、膨張水の漏れを完全に防止できるので、節水も図ることができる。Further, since it is possible to completely prevent the expansion water from leaking, it is possible to save water.
