Description
本発明は、洗面台あるいは流し台の下方に設置し、異なった二種の温度の湯を供給する電気温水器に関する発明である。 The present invention is an invention relating to an electric water heater that is installed below a sink or sink and supplies hot water of two different temperatures.
これまでの事例では、接続口を固定する固定部材を器具側面または背面ケースに固定し、逃し弁の組み立て性とメンテナンス性を向上させた電気温水器(特許文献１に記載)および接続口を回転可能なエルボとすることで上面に十分なスペースがない場合でも配管を可能とした即湯器(特許文献２に記載)の例があった。 In the past examples, the fixing member that fixes the connection port is fixed to the side or back case of the instrument, and the electric water heater (described in Patent Document 1) and the connection port that improve the assembly and maintenance of the relief valve are rotated. There has been an example of an instant water heater (described in Patent Document 2) in which piping is possible even when there is not enough space on the upper surface by using a possible elbow.
ただし、特許文献１については加熱用ヒーターを備えた貯湯タンクからの湯を供給する電気温水器に関しての記述であり、特許文献２についてはセントラル熱源から来る湯を貯湯タンクで加熱部により加熱された湯を供給する即湯器に関しての記述であり、そのいずれもが一種の湯を供給するシステムに関するものであり、いずれも、単一温度の湯を供給する電気温水器に関するものであった。
However, Patent Document 1 describes an electric water heater that supplies hot water from a hot water storage tank equipped with a heater for heating, and Patent Document 2 describes hot water coming from a central heat source heated by a heating unit in the hot water storage tank. a description of the terms immediate water for supplying hot water, any of which relates to a system for supplying hot water type, any, was related to electric water heater supplying hot water of a single temperature.
従来、電気温水器を洗面台あるいは流し台の下方に設置する場合、排水管との干渉および物の収納性を考慮して流し台の真下を避け、電気温水器を流し台の下方右あるいは左に寄せ設置する場合がほとんどである。このため前記接続口を電気温水器側面の右方あるいは左方、または製品上面に配置する構造が一般的である。
Conventionally, when installing an electric water heater below the wash basin or sink, avoiding the area directly below the sink in consideration of interference with the drain pipe and storage capacity, place the electric water heater to the right or left below the sink. In most cases. For this reason, the structure which arrange | positions the said connection port to the right or left of the electric water heater side surface, or the product upper surface is common.
しかしながら、貯湯された温度の湯と貯湯温度の湯と上水を混合した温度の湯の異なった温度の湯を同時に供給する電気温水器の場合、貯湯された湯を流通させる出湯配管と貯湯された湯と上水を混合する混合バルブおよびそれに連結する配管が必要になり、それらをケース内に収納して、側方に配置する場合は上記のように前記接続口を電気温水器側面に配置する構造となり、当該構造においては電気温水器の横幅が必要以上に大きくなってしまうという欠点が、また電気温水器上面に配置する構造においては製品の高さが必要以上に大きくなってしまうという欠点がそれぞれあった。
However, in the case of an electric water heater that supplies hot water of different temperatures, such as hot water of stored hot water, hot water of hot water of stored temperature, and hot water of hot water, the hot water stored in the hot water piping and the hot water are stored. A mixing valve that mixes hot water and tap water and piping connected to it are required. When these are stored in the case and placed on the side, the connection port is placed on the side of the electric water heater as described above. In the structure, the disadvantage that the width of the electric water heater becomes larger than necessary, and in the structure arranged on the upper surface of the electric water heater, the height of the product becomes larger than necessary. There were each.
さらに、貯湯された温度の湯と貯湯温度の湯と上水を混合した温度の湯の異なった温度湯を同時に供給する電気温水器においては一種の湯を供給する電気温水器と比べ、各接続口と相手配管と接続する配管の数が増えるため、配管の接続がより複雑となり、配管同士が交叉したり、洗面台あるいは流し台の排水管と干渉してしまう問題がある。 Furthermore, in the electric water heater that supplies hot water of different temperature, which is a mixture of hot water of stored hot water, hot water of stored hot water and clean water, each connection compared to an electric water heater that supplies a kind of hot water Since the number of pipes connected to the mouth and the counterpart pipe increases, the connection of the pipes becomes more complicated, and there is a problem that the pipes cross each other and interfere with the drainage pipes of the sink or sink.
これにより、貯湯タンクの側面に各接続口を配置すると、配管の取り回しによる専有のスペースが必要となるので電気温水器の横幅が増大することとなる。その結果、洗面台あるいは流し台の下方の空間の大部分が使用不能となり物を収納するといった有効な活用スペースが縮小されるという問題があった。 Thereby, when each connection port is arranged on the side surface of the hot water storage tank, a space dedicated to the piping is required, so that the width of the electric water heater increases. As a result, there has been a problem that an effective use space in which most of the space below the sink or sink becomes unusable and stores things is reduced.
また、相手配管との接続に関しては電気温水器から向かって右側から接続する場合や電気温水器から向かって左側から接続する場合の両方の要求があり、洗面台あるいは流し台の下方の左右どちらにも設置できるように配慮しなければならない。そのため、製品側面に接続口を配置する構造の電気温水器においてはそれに対応するために左右どちらかの側面に接続口を配置するという２つの構造を用意せねばならないという不便さがあった。
In addition, regarding the connection with the other pipe, there is a requirement both when connecting from the right side when facing from the electric water heater and when connecting from the left side when facing from the electric water heater, both on the left and right below the sink or sink Care must be taken so that it can be installed. Therefore, in the electric water heater having a structure in which the connection port is arranged on the side surface of the product, there is an inconvenience that it is necessary to prepare two structures in which the connection port is arranged on either the left or right side in order to cope with it.
したがって、本発明の目的は洗面台あるいは流し台の下方の左右どちら側に設置されても、各接続口と相手配管との接続が可能な異なった温度の湯を同時に２ヶ所以上に供給できる電気温水器を提供することにある。
Therefore, the object of the present invention is to provide electric hot water that can supply hot water of different temperatures that can be connected to each connection port to the other pipe at the same time, regardless of whether it is installed on the left or right side below the sink or sink. Is to provide a vessel.

The upper surface and side surface, and the bottom surface and side surface are configured as a single case, but the upper surface, the bottom surface, and the side surface may be configured separately.
図２は、本発明の一実施形態に係わる電気温水器の上面方向からの内観図である。
ここで、上面ケースは、上面前方ケース１７、上面中央ケース２１、上面背面ケース１８に分割されている。給水口４、出水口７、混合湯口１６は貯湯タンク２の前面且つ上部より一段低い個所に位置する上面前方ケース１７に固定されている。また、出湯口８、膨張水排水口１４は底面側面ケース１９（図示せず）に固定されている。出湯口８は貯湯タンク２の中心と左右の側面までの距離が同一になるように配置して、尚且つ、前記貯湯タンクの上部の略中心部と接続される内部出湯接続口２２に接続され、内部出湯接続口２２を左右回動自在であるようにしている。また、内部出湯接続口２２の軸を中心に回転させることで、出湯口８の左右側面の取付けを自由に選択できる。また、膨張水排水口１４についても、同様に左右側面の取付けを自由に選択できる。
FIG. 2 is an interior view of the electric water heater according to the embodiment of the present invention from the upper surface direction.
Here, the upper surface case is divided into an upper surface front case 17, an upper surface center case 21, and an upper surface rear case 18. The water supply port 4, the water discharge port 7, and the mixing pouring gate 16 are fixed to an upper front case 17 located at a position one step lower than the front surface and the upper part of the hot water storage tank 2. Further, the hot water outlet 8 and the expanded water drain port 14 are fixed to a bottom side case 19 (not shown). The hot water outlet 8 is disposed so that the distance from the center of the hot water storage tank 2 to the left and right side surfaces is the same, and is connected to an internal hot water connection port 22 connected to the substantially central portion of the upper part of the hot water storage tank. The internal hot water connection port 22 is configured to be rotatable left and right. Further, by rotating about the axis of the internal hot water outlet connection port 22, attachment of the left and right side surfaces of the hot water outlet 8 can be freely selected. Similarly, the left and right side attachments can be freely selected for the expanded water drain port 14 as well.
図３は、本発明の一実施形態に係わる電気温水器の正面向かって右側面内観図である。
上水は給水口４より入水し、減圧弁５を連通し、入水分岐管６（図示せず）より貯湯タンク２に通じる経路および出水口７に通じる経路および混合バルブ１５を経由して混合湯口１６に通じる経路にそれぞれ分岐される。したがって、給水口４、出水口７、混合湯口１６は減圧弁５、入水分岐管６（図示せず）、混合バルブ１５を介して連通しているため、ひとつのブロックとして扱う方が余分な配管や配管の曲がりが発生することなく適している。また、給水口４、出水口７、混合湯口１６は側面より見て、それぞれの口の中心位置を前後方向にずらしているので、配管が容易に接続でき互いに干渉がなくなる。
次に、給水口４、出水口７、混合湯口１６の配置としては電気温水器の側方あるいは上面に集中して配置するやり方は、前述の通り、製品寸法が大きくなってしまう欠点が発生する。
FIG. 3 is an inner side view of the right side of the electric water heater according to the embodiment of the present invention.
Water enters from the water supply port 4, communicates with the pressure reducing valve 5, passes through the water inlet branch pipe 6 (not shown) to the hot water storage tank 2, passes through the water outlet 7, and mixes through the mixing valve 15. Branches to routes leading to 16 respectively. Accordingly, since the water supply port 4, the water outlet 7 and the mixing tap 16 are communicated with each other via the pressure reducing valve 5, the incoming water branch pipe 6 (not shown), and the mixing valve 15, it is more necessary to handle as one block. It is suitable without bending of pipes and pipes. Further, since the water supply port 4, the water outlet 7 and the mixing tap 16 are viewed from the side, the center positions of the respective ports are shifted in the front-rear direction, so that the pipes can be easily connected and no interference occurs.
Next, the manner of placing the water supply port 4, water outlet 7, as the arrangement of the mixing sprue 1 6 concentrated on the side or upper surface of the electric water heater, as described above, the drawback of product dimensions becomes large appear.
その欠点を解消するために、減圧弁５を前面に配置し、それに連通する給水口４、出水口７、混合湯口１６もともに前面に配置することで、貯湯タンク２の側方に配置される取り回しの配管がなくなる。そのため、電気温水器側方の寸法がほぼ貯湯タンク２の寸法に抑えることができ、かつ給水口４、出水口７、混合湯口１６を前面かつ上部より一段低い個所に位置する上面前方ケース１７に固定することで電気温水器上面部に突出する部位がなく、高さ寸法も極力抑えることが可能となる。
In order to eliminate the drawbacks, the pressure reducing valve 5 is disposed on the front surface, and the water supply port 4, the water discharge port 7 and the mixed water spout 16 connected to the pressure reducing valve 5 are also disposed on the front surface so that they are disposed on the side of the hot water storage tank 2. There is no longer any handling piping. Therefore, electricity can be the size of the water heater side is suppressed to almost the size of the hot water storage tank 2, and water supply port 4, water outlet 7, top front case the mixing sprue 1 6 located one step lower location than the front and top By fixing to 17, there is no portion projecting from the upper surface portion of the electric water heater, and the height dimension can be suppressed as much as possible.
他方、貯湯タンク２の天部から出湯口配管９に接続される出湯口８および同じく貯湯タンク２の天部から逃し弁１１を経由して膨張水排水配管１３に接続される膨張水排水口１４は貯湯タンク２の背面側部かつ上面背面ケース１８の側面上部に配置されている。異なる温度の湯を供給する混合湯口１６および出湯口８が貯湯タンクの前面および背面にそれぞれ分けられ配置することになり、内部配管のレイアウトがバランスのとれたものに仕上がっている。
On the other hand, a hot water outlet 8 connected from the top of the hot water storage tank 2 to the hot water outlet pipe 9 and an expansion water drain 1 connected from the top of the hot water storage tank 2 to the expansion water drain pipe 13 via the relief valve 11. Reference numeral 4 denotes a rear side portion of the hot water storage tank 2 and an upper side surface of the upper surface rear case 18 . The mixed hot water outlet 16 and the hot water outlet 8 for supplying hot water of different temperatures are arranged separately on the front surface and the rear surface of the hot water storage tank, so that the layout of the internal piping is balanced.
膨張水排水口１４も出湯口８と同様、電気温水器背面に配置してあり、膨張水を排水管に排出するため、膨張水排水口１４を排水管に接続する際に電気温水器背面側方での連結となり、正面近くに接続配管がくることがなく、電気温水器まわりがすっきりと仕上がることになる。
Similar to the expansion water discharge Mizuguchi 14 also outflow 8, electricity Yes disposed in water heater back, for discharging the expansion water to drain, electricity water heater when connecting the expansion water discharge water outlet 14 to drain become a consolidated at the back side, without coming connecting pipe near the front, is around electric water heaters will be finished and clean.
膨張水排水口１４が連結する逃し弁１１も減圧弁５と同様、正面に配置することで点検および交換の対象とされるこれら２部品に対して、保守、メンテナンス時の扱いが非常に楽なものとなる。これらの２部品が電気温水器側方に配置されている場合、狭い作業スペースを考えると、配管が取りついた状態での交換作業は不可能であり、電気温水器に接続される全ての配管を取り外し、正面に向きを置き直した状態での交換作業となる問題が解消される。
Relief valve 11 which expands water discharge Mizuguchi 14 is linked as well as pressure reducing valve 5, with respect to these two parts to be subject to inspection and replacement by arranging the front, maintenance, and very easy handling for maintenance It will be a thing. When these two parts are arranged on the side of the electric water heater, considering the narrow work space, replacement work with the pipe attached is impossible, and all the pipes connected to the electric water heater This eliminates the problem of replacement work in a state where the camera is removed and the orientation is changed to the front.
図４は本発明の一実施形態に係わる電気温水器の出湯口と膨張水排水口と固定板の取り付け斜視図である。図示で出湯口配管９と内部出湯接続口２２はクイックファスナ２３により接続され、固定板２０と内部出湯接続口２２はビス２４により固定されている。そのため、出湯口配管９に接続される出湯口８は内部出湯接続口２２の軸を中心に回動自在な構造を有している。ここでは、クイックファスナ２３を用いることで、出湯口配管９と内部出湯接続口２２を固定することなく漏水せずに配管可能となる。次に図示で膨張水排水配管１３と膨張水配管１２はクイックファスナ２３により接続され、固定板２０と膨張水配管１２はビス２４により固定されている。そのため、膨張水配管１２に接続される膨張水排水配管１３は回動自在な構造を有す。ここでは、クイックファスナ２３を用いることで、膨張水排水配管１３と膨張水配管１２を固定することなく漏水せずに配管可能となる。
FIG. 4 is a perspective view of the electric water heater according to an embodiment of the present invention, which is attached to the outlet, the expansion water drain, and the fixing plate . In the drawing, the hot water outlet pipe 9 and the internal hot water connection port 22 are connected by a quick fastener 23, and the fixing plate 20 and the internal hot water connection port 22 are fixed by screws 24. Therefore, the hot water outlet 8 connected to the hot water outlet pipe 9 has a structure that can rotate around the axis of the internal hot water connection port 22. Here, by using the quick fastener 23, the hot water outlet pipe 9 and the internal hot water connection port 22 can be fixed without being leaked. Then inflation Mizuhai tube 12 and the expansion water drain pipe 13 shown is connected by the quick fasteners 23, the fixing plate 20 and the expansion Mizuhai tube 12 is fixed by screws 24. Therefore, the expansion water drain pipe 13 connected to the expansion water piping 12 having a rotatable structure. Here, by using a quick fastener 23, thereby enabling the pipe without leakage without fixing the expansion water drain pipe 13 to the expansion Mizuhai tube 12.
図５は本発明の一実施形態に係わる電気温水器の出水口とケースの取付け前の斜視図である。図示で押え板２７は出水口７の側面溝部にはめ込まれ、押え板２７、上面前方ケース１７、および出水口内部接続口２５はビス２４により固定されている。また出水口内部接続口２５と出水口配管２６はクイックファスナ２３により接続されている。そのため出水口７は上面前方ケース１７の平面上で自由に回転することができ、任意の位置で相手配管との接続が可能となる。同様に給水口４（図示せず）、混合湯口１６（図示せず）についても出水口７と同じ構造を有することから、上面前方ケース１７に固定される給水口４、出水口７、混合湯口１６は任意の位置で相手配管との接続が可能となり、施工時相手配管との取り合い上の制約が大幅に解消されることとなる。
FIG. 5 is a perspective view of the electric water heater according to the embodiment of the present invention before the water outlet and the case are attached . In the figure, the presser plate 27 is fitted in the side groove of the water outlet 7, and the presser plate 27, the upper surface front case 17, and the water outlet inner connection port 25 are fixed by screws 24. Further, the water outlet internal connection port 25 and the water outlet pipe 26 are connected by a quick fastener 23. Therefore, the water outlet 7 can freely rotate on the plane of the upper front case 17 and can be connected to the other pipe at an arbitrary position. Similarly, since the water supply port 4 (not shown) and the mixing gate 16 (not shown) have the same structure as the water outlet 7, the water supply port 4, the water outlet 7 and the mixing gate fixed to the upper front case 17 are provided.
