Description

本発明は、浴室の壁面に設置して使用される給湯器用のリモコンなどの壁面設置型リモコンに関する。   The present invention relates to a wall-mounted remote controller such as a remote controller for a water heater used by being installed on a wall surface of a bathroom.

壁面設置型リモコンの具体例としては、特許文献１，２に記載されたものがある。これらの文献に記載されたリモコンは、たとえば浴室の壁面に取り付けられる筐体内に、回路基板やその他の電気部品が収容されて、筐体の前面部には操作スイッチが設けられた構成を有している。筐体の背面壁部には、電気配線引き出し用の孔部が設けられているとともに、弾性部材からなるシール用のパッキンが貼付されている。このパッキンは、リモコンが浴室の壁面に取り付けられたとき、浴室の壁面と筐体の背面壁部との間に挟まれて圧縮し、電気配線引き出し用の孔部の周囲をシールする。このため、水や湯気などが前記孔部から筐体内に進入することは防止される。   Specific examples of the wall-mounted remote control include those described in Patent Documents 1 and 2. The remote control described in these documents has a configuration in which, for example, a circuit board and other electrical components are housed in a housing attached to the wall of a bathroom, and an operation switch is provided on the front surface of the housing. ing. The back wall of the housing is provided with a hole for drawing out the electric wiring, and a seal packing made of an elastic member is attached. When the remote control is attached to the wall surface of the bathroom, the packing is sandwiched between the wall surface of the bathroom and the back wall portion of the casing and compressed, and seals the periphery of the hole for drawing out the electric wiring. For this reason, it is prevented that water, steam, etc. enter into a housing | casing from the said hole.

しかしながら、前記従来技術においては、次に述べるように、改善すべき余地があった。   However, the prior art has room for improvement as described below.

すなわち、壁面設置型リモコンは、取り付け対象の壁面からその前方に突出した状態に設置されるために、嵩張りを抑制し、見栄えを良好にする観点などから、薄型化が強く要請される場合が多い。これに対し、前記した従来のリモコンは、筐体内に回路基板やその他の電気部品を単に収容させた構造に過ぎず、たとえば回路基板に高さが比較的高い電気部品が実装されている場合には、この電気部品と筐体との干渉を回避する必要から筐体の前後方向の厚みを比較的大きく取らざるを得ない。また、筐体の背面壁部と取り付け対象の壁面との間にパッキンが介装された構造においては、取り付け対象の壁面からリモコンが突出する寸法は、筐体の厚みに加えて、パッキンの厚み寸法も加算されたものとなる。このようなことから、従来のリモコンにおいては、壁面からの突出寸法が大きめになり易く、全体の薄型化を図る上で改善すべき余地があった。   In other words, since the wall-mounted remote control is installed in a state protruding forward from the wall surface to be attached, there is a case where it is strongly required to reduce the thickness from the viewpoint of suppressing bulkiness and improving the appearance. Many. On the other hand, the above-described conventional remote controller is merely a structure in which a circuit board and other electrical components are simply housed in a housing. For example, when a relatively high electrical component is mounted on the circuit board. However, since it is necessary to avoid the interference between the electrical component and the housing, the thickness of the housing in the front-rear direction must be relatively large. Further, in the structure in which the packing is interposed between the rear wall portion of the casing and the wall surface to be attached, the dimension that the remote control protrudes from the wall surface to be attached is the thickness of the packing in addition to the thickness of the casing. The dimensions are also added. For this reason, in the conventional remote control, the projecting dimension from the wall surface tends to be large, and there is room for improvement in reducing the overall thickness.

本発明は、前記したような事情のもとで考え出されたものであって、薄型化を好適に図ることが可能な壁面設置型リモコンを提供することを、その課題としている。   The present invention has been conceived under the circumstances as described above, and an object thereof is to provide a wall-mounted remote controller that can be suitably reduced in thickness.

上記の課題を解決するため、本発明では、次の技術的手段を講じている。   In order to solve the above problems, the present invention takes the following technical means.

本発明により提供される壁面設置型リモコンは、内部に電気部品を収容し、かつ電気配線引き出し用の孔部が背面壁部に形成されている筐体と、この筐体を取り付け対象の壁面に取り付けた際に、この壁面と前記筐体の背面壁部との間に挟まれて圧縮し、前記孔部の周囲をシールするパッキンと、を備えている、壁面設置型リモコンであって、前記筐体の背面壁部のうち、前記パッキンを避けた位置には、前記パッキンの圧縮時の厚み以下の高さで前記筐体の背後に張り出し、かつ前記筐体の内側に凹部を形成する張り出し部が設けられており、前記筐体内の少なくとも１つの電気部品は、前記張り出し部の正面に配置されて前記凹部に進入していることにより、前記筐体の背面壁部との干渉が回避された構成とされており、前記筐体の背面壁部には、前記パッキンの非圧縮時の厚みよりも前記筐体の背面側への突出寸法が小さく、かつ前記筐体を前記壁面に取り付ける際に先端部が前記壁面に当接することによって前記パッキンの圧縮量を規定することが可能な壁面当接用の突出部が設けられており、前記張り出し部は、前記壁面当接用の突出部の突出寸法以下の突出高さとされていることを特徴としている。 The wall-mounted remote controller provided by the present invention includes a housing that houses electrical components therein and has a hole for electrical wiring drawing formed in the back wall, and the housing is attached to the wall to be attached. A wall-mounted remote control comprising a packing that is sandwiched between the wall surface and the back wall portion of the housing to compress and seals the periphery of the hole portion when attached, In the rear wall portion of the casing, a position where the packing is avoided is projected to the back of the casing at a height equal to or less than the thickness when the packing is compressed, and a recess is formed inside the casing. And at least one electrical component in the housing is disposed in front of the overhanging portion and enters the recess, thereby avoiding interference with the rear wall portion of the housing. was being configured, the back of the housing The part has a smaller projecting dimension toward the back side of the casing than the thickness when the packing is not compressed, and a tip part abuts against the wall surface when the casing is attached to the wall surface. The wall surface abutting protrusion that can regulate the amount of compression of the wall surface is provided, and the overhanging portion has a protrusion height equal to or less than the protruding dimension of the wall surface abutting protrusion. It is said.

このような構成によれば、筐体の背面壁部に設けられた張り出し部の凹部が筐体内に形成されている分だけ、筐体内の容積の増大化が図られており、前記凹部を有効に利用して電気部品が筐体内にスペース効率良く配置される。一方、前記張り出し部は、シール用のパッキンの圧縮時の厚み以下の高さであって、かつ前記パッキンを避けた位置に設けられているために、この張り出し部の存在に起因して、取り付け対象の壁面から筐体が突出する寸法が増大することはない。もちろん、パッキンによる止水シール性能を阻害するといったこともない。このようなことから、本発明によれば、取り付け対象の壁面からの筐体の突出寸法、ひいてはリモコン全体の突出寸法を従来よりも小さくし、その薄型化を好適に図ることができる。
さらに、このような構成によれば、壁面当接用の突出部を利用してパッキンの圧縮量を適切に規定し、パッキンが取り付け対象の壁面とリモコンの筐体との間で過度に圧縮されたり、あるいは圧縮不足となってシール性能が劣るものになるといったことを適切に防止することができる。 According to such a configuration, the volume in the housing is increased by the amount that the recessed portion of the projecting portion provided in the back wall portion of the housing is formed in the housing, and the recessed portion is effectively used. For this reason, the electrical components are arranged in the casing with good space efficiency. On the other hand, since the overhanging portion is provided at a position that is less than the thickness when the packing for sealing is compressed and avoids the packing, it is attached due to the presence of the overhanging portion. The dimension that the casing projects from the target wall surface does not increase. Of course, there is no impediment to the water sealing performance of the packing. For this reason, according to the present invention, the projecting dimension of the housing from the wall surface to be attached, and thus the projecting dimension of the entire remote control can be made smaller than before, and the thickness can be suitably reduced.
Further, according to such a configuration, the amount of compression of the packing is appropriately regulated by using the protruding portion for wall surface contact, and the packing is excessively compressed between the wall surface to be attached and the casing of the remote control. Or poor compression and poor sealing performance can be appropriately prevented.

本発明において、好ましくは、前記筐体内には、回路基板が収容され、かつこの回路基板の背面側に実装されている部品のうち、前記回路基板からの突出寸法が最も大きい部品の頭部が前記凹部に進入している。   In the present invention, preferably, a head of a component having a largest projecting dimension from the circuit board among components mounted on the back side of the circuit board is accommodated in the housing. It has entered the recess.

このような構成によれば、リモコン全体の薄型化を図るのにより好ましい。   According to such a configuration, it is more preferable to make the entire remote control thinner.

本発明において、好ましくは、前記張り出し部は、前記壁面当接用の突出部を兼用した構成とされている。   In the present invention, preferably, the overhanging portion is configured to also serve as the protruding portion for contacting the wall surface.

このような構成によれば、張り出し部とは別個に壁面当接用の突出部を設ける必要が無くなり、または少なくなり、全体構造の簡素化を図ることができる。   According to such a configuration, it is not necessary or less necessary to provide the protruding portion for wall surface contact separately from the overhanging portion, and the overall structure can be simplified.

本発明において、好ましくは、前記張り出し部は、複数設けられ、かつこれら複数の張り出し部は、前記筐体の略矩形状の背面壁部における四隅領域またはそれらの近傍に位置している。   In the present invention, preferably, a plurality of the overhang portions are provided, and the plurality of overhang portions are located at or near the four corner regions of the substantially rectangular back wall portion of the casing.

このような構成によれば、リモコンを取り付け対象の壁面に設置する際に、各張り出し部の先端部を取り付け対象の壁面に当接させることにより、筐体が壁面に対して傾かないように安定させた姿勢に設定することが可能である。各張り出し部とは別に壁面当接用の突出部を設ける必要はない。   According to such a configuration, when the remote control is installed on the wall surface to be attached, the tip of each overhanging portion is brought into contact with the wall surface to be attached, so that the housing does not tilt with respect to the wall surface. It is possible to set the posture to be changed. It is not necessary to provide a protruding portion for contacting the wall surface separately from each overhanging portion.

本発明のその他の特徴および利点は、添付図面を参照して以下に行なう発明の実施の形態の説明から、より明らかになるであろう。   Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

以下、本発明の好ましい実施の形態について、図面を参照して具体的に説明する。   Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

図１〜図５は、本発明が適用された壁面設置型リモコンの一例を示している。
本実施形態の壁面設置型リモコンＲ（以下、リモコンＲと略称する）は、給湯器用のリモコンであり、図１に示すように、浴室の壁面９に取り付けられて使用される。図２〜図４に示すように、リモコンＲは、筐体Ｃを構成する前側部材１および後側部材２、回路基板３、化粧カバー４、ならびにシール用のパッキン５を具備している。 1 to 5 show an example of a wall-mounted remote controller to which the present invention is applied.
A wall-mounted remote controller R (hereinafter abbreviated as “remote controller R”) of this embodiment is a remote controller for a water heater, and is used by being attached to a wall surface 9 of a bathroom as shown in FIG. As shown in FIGS. 2 to 4, the remote controller R includes a front member 1 and a rear member 2, a circuit board 3, a decorative cover 4, and a seal packing 5 that constitute the casing C.

筐体Ｃは、正面視矩形状であって、前後厚み方向の薄型化が図られた略直方体状である。筐体Ｃを構成する前側部材１および後側部材２は、ともにＡＢＳ樹脂などの樹脂製であり、それらの厚み方向に重ね合わされて互いに接合されている。このことにより、筐体Ｃ内には、回路基板３その他の後述する電気部品（電子部品も含む）を収容するための空間領域が形成されている。前側部材１は、開口窓１２が形成された前面壁部１３と、この前面壁部１３の外周縁からその背後に突出した突縁部１４とを有している。前側部材1には、複数の操作スイッチを有する操作部３２が設けられている。後側部材２は、矩形平板状の背面壁部２０と、この背面壁部２０の外周縁からその正面方向に突出した突縁部２１とを有している。   The casing C has a rectangular shape when viewed from the front, and has a substantially rectangular parallelepiped shape that is thinned in the front-rear thickness direction. Both the front member 1 and the rear member 2 constituting the housing C are made of resin such as ABS resin, and are overlapped and joined to each other in the thickness direction. Thus, a space region for accommodating the circuit board 3 and other electric components (including electronic components) to be described later is formed in the housing C. The front member 1 has a front wall portion 13 in which an opening window 12 is formed, and a protruding edge portion 14 protruding from the outer peripheral edge of the front wall portion 13 to the back thereof. The front member 1 is provided with an operation unit 32 having a plurality of operation switches. The rear member 2 includes a rectangular flat plate-like rear wall 20 and a protruding edge 21 that protrudes from the outer peripheral edge of the rear wall 20 in the front direction.

回路基板３は、基板本体３０に複数の電気部品が実装されたものであり、給湯器の運転のオン・オフや目標給湯温度の設定制御などを行なうためのデータ処理回路を構築している。回路基板３の前面側には、液晶表示器などの画像表示器３１が設けられており、その表示画面３１ａは、筐体Ｃの開口窓１２を介して目視可能である。また、回路基板３には、操作部３２が操作された際に可動部材３２ａを介して押圧されることにより所定のスイッチング動作を行なうスイッチング回路部３２ｂも搭載されている。   The circuit board 3 has a plurality of electrical components mounted on the board body 30, and constructs a data processing circuit for performing on / off operation of the water heater, setting control of the target hot water temperature, and the like. An image display 31 such as a liquid crystal display is provided on the front side of the circuit board 3, and the display screen 31 a is visible through the opening window 12 of the housing C. The circuit board 3 is also equipped with a switching circuit portion 32b that performs a predetermined switching operation by being pressed through the movable member 32a when the operation portion 32 is operated.

図２に示すように、シール用のパッキン５は、筐体Ｃの背面壁部２０と壁面９との間に挟まれて、電気配線引き出し用の孔部１５の周囲をシールするためのものである。このパッキン５は、合成ゴムや発泡樹脂などの弾性部材からなり、背面壁部２０に貼着されている。図５に示すように、このパッキン５は、電気配線引き出し用の孔部１５の周縁部を囲む第１のリング部５１と、この第１のリング部５１に繋がってこの第１のリング部５１の周囲を囲む第２のリング部５２とを有している。このような２重リング構造は、特許文献２の図９に示されたものと同様であり、パッキン５の体積を小さくしつつ、シール面積を大きくとることができる。また、パッキン５を介して筐体Ｃを壁面９に接着させた後に、このパッキン５をカッタなどによって切断し、筐体Ｃを壁面９から引き剥がす際に、その作業を容易にできる利点もある。本実施形態においては、パッキン５を前記した２重リング構造としたことにより、筐体Ｃの背面壁部２０にパッキン５が設けられていない領域を広くとることが可能となり、パッキン５の位置を避けるようにして背面壁部２０に後述する張り出し部１６を設けるのに好都合となる。   As shown in FIG. 2, the seal packing 5 is sandwiched between the back wall 20 and the wall 9 of the casing C and seals the periphery of the hole 15 for drawing out the electrical wiring. is there. The packing 5 is made of an elastic member such as synthetic rubber or foamed resin, and is attached to the back wall portion 20. As shown in FIG. 5, the packing 5 includes a first ring portion 51 that surrounds the peripheral portion of the hole portion 15 for drawing out the electrical wiring, and the first ring portion 51 that is connected to the first ring portion 51. And a second ring portion 52 surrounding the periphery of the. Such a double ring structure is the same as that shown in FIG. 9 of Patent Document 2, and the seal area can be increased while reducing the volume of the packing 5. Further, there is an advantage that when the casing C is bonded to the wall surface 9 via the packing 5, the packing 5 is cut by a cutter or the like, and the casing C is peeled off from the wall surface 9, so that the work can be facilitated. . In this embodiment, since the packing 5 has the above-described double ring structure, a region where the packing 5 is not provided on the back wall portion 20 of the housing C can be widened, and the position of the packing 5 can be determined. In order to avoid this, it is convenient to provide a protruding portion 16 to be described later on the back wall portion 20.

筐体Ｃの背面壁部２０には、壁面当接用の突出部１７、および張り出し部１６が設けられている。壁面当接用の突出部１７は、背面壁部２０の四隅部分またはその近傍に設けら
れており、その形状は、たとえば筐体Ｃの背面視においてＬ字状である。この突出部１７は、筐体Ｃを壁面９に取り付ける際にその先端部を壁面９に当接させて筐体Ｃの取り付けを安定させるのに役立つ。突出部１７の突出高さＨ１は、パッキン５が圧縮されていない自然状態にある際の厚みｔ１よりも小さい寸法である（図３を参照）。このため、筐体Ｃが壁面９に取り付けられる際には、パッキン５は前記の高さＨ１と同等高さまで圧縮される（図２を参照）。このように、突出部１７はパッキン５の圧縮変形量を規定する役割をも果たす。 The rear wall 20 of the housing C is provided with a protrusion 17 for wall surface contact and an overhang 16. The wall surface abutting protrusions 17 are provided at or near the four corners of the back wall 20, and the shape thereof is, for example, L-shaped when the housing C is viewed from the back. The protrusion 17 is useful for stabilizing the attachment of the casing C by abutting the tip of the casing C on the wall surface 9 when the casing C is attached to the wall surface 9. The protrusion height H1 of the protrusion 17 is smaller than the thickness t1 when the packing 5 is in a natural state where the packing 5 is not compressed (see FIG. 3). For this reason, when the housing | casing C is attached to the wall surface 9, the packing 5 is compressed to the height equivalent to the said height H1 (refer FIG. 2). Thus, the protrusion 17 also serves to define the amount of compressive deformation of the packing 5.

張り出し部１６は、筐体Ｃの背面壁部２０の一部を筐体Ｃの背後に張り出させた部分であり、パッキン５を避けた位置に設けられている。この張り出し部１６は、筐体Ｃの内側に凹部１６ａを形成している。回路基板３の背面側に実装されている電気部品のうち、最も背の高い電気部品３９は、張り出し部１６の正面に配置され、かつその頭部は凹部１６ａに進入している。張り出し部１６の突出高さＨ２は、壁面当接用の突出部１７の高さＨ１以下であり、この張り出し部１６の存在によって突出部１７の前記した機能が妨げられないように構成されている。   The overhanging portion 16 is a portion in which a part of the back wall portion 20 of the housing C is overhanging behind the housing C, and is provided at a position where the packing 5 is avoided. The projecting portion 16 has a recess 16 a formed inside the housing C. Of the electrical components mounted on the back side of the circuit board 3, the tallest electrical component 39 is disposed in front of the overhanging portion 16, and its head enters the recess 16a. The protruding height H2 of the overhanging portion 16 is equal to or less than the height H1 of the protruding portion 17 for contacting the wall surface, and the presence of the overhanging portion 16 is configured so that the function of the protruding portion 17 is not hindered. .

筐体Ｃを壁面９に取り付けるための手段としては、たとえば図４に示すように、筐体Ｃに設けられたネジ体挿通用孔１９，２９に固定用のネジ体２８を挿通して行なうネジ止手段を用いることができる。これに代えて、壁面９に開口した貫通孔９０にステイパイプと称される部材（図示略）を配置し、この部材に筐体Ｃを支持させる手段を採用することもできる。電気配線３３は、貫通孔９０に挿通されて屋外に引き出され、制御対象の給湯器の制御部に接続される。化粧カバー４は、筐体Ｃにその正面側から外嵌装着されて、ネジ体２８などを覆い隠し、全体の体裁を美麗に整えるのに役立つ。この化粧カバー４には、表示画面３１ａおよび操作部３２の露出用の開口窓４０が設けられている。   As a means for attaching the casing C to the wall surface 9, for example, as shown in FIG. 4, a screw is formed by inserting a fixing screw body 28 into screw body insertion holes 19 and 29 provided in the casing C. Stop means can be used. Instead of this, a member (not shown) called a stay pipe may be disposed in the through hole 90 opened in the wall surface 9, and a means for supporting the casing C on this member may be employed. The electrical wiring 33 is inserted through the through hole 90 and pulled out outdoors, and is connected to the control unit of the water heater to be controlled. The decorative cover 4 is externally fitted to the housing C from the front side thereof, covers and conceals the screw body 28 and the like, and helps to make the overall appearance beautiful. The decorative cover 4 is provided with an opening window 40 for exposing the display screen 31 a and the operation unit 32.

次に、前記したリモコンＲの作用について説明する。   Next, the operation of the remote controller R will be described.

筐体Ｃに設けられた張り出し部１６の凹部１６ａには、回路基板３に実装されている電気部品のうち、最も背の高い電気部品３９の頭部が進入しているために、この電気部品３９と背面壁部２０との干渉を回避しつつ、背面壁部２０と回路基板３との距離Ｌ１を短くすることができる（図２を参照）。このことにより、筐体Ｃ自体の薄型化を好適に図ることができる。   Since the head of the tallest electrical component 39 among the electrical components mounted on the circuit board 3 has entered the recess 16a of the overhanging portion 16 provided in the casing C, this electrical component The distance L1 between the back wall 20 and the circuit board 3 can be shortened while avoiding the interference between the back wall 39 and the back wall 20 (see FIG. 2). As a result, the casing C itself can be made thinner.

一方、張り出し部１６は、壁面当接用の突出部１７の突出高さＨ１（パッキン５の圧縮時の厚み寸法）以下の高さで、パッキン５を避けた位置に設けられているために、この張り出し部１６の存在に起因して、壁面９からの筐体Ｃの突出寸法が増大する不具合はない。したがって、このリモコンＲの設置構造においては、壁面９の前方にリモコンＲが大きな寸法で嵩張った状態となることを抑制し、薄型化が図られた体裁の良いものとすることが可能である。パッキン５による止水シール性能が張り出し部１６によって阻害されるといった不具合もない。   On the other hand, the overhanging portion 16 has a height equal to or lower than the protruding height H1 (thickness dimension when the packing 5 is compressed) of the protruding portion 17 for wall surface contact, and is provided at a position avoiding the packing 5. Due to the presence of the overhanging portion 16, there is no problem that the protruding dimension of the casing C from the wall surface 9 increases. Therefore, in the installation structure of the remote controller R, the remote controller R can be prevented from becoming bulky in a large dimension in front of the wall surface 9, and the appearance can be improved with a reduced thickness. . There is no problem that the waterproof seal performance by the packing 5 is hindered by the overhanging portion 16.

図６および図７は、本発明の他の実施形態を示している。前記実施形態と同一または類似の要素には、前記実施形態と同一の符号を付している。   6 and 7 show another embodiment of the present invention. Elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment.

図６に示す実施形態においては、張り出し部１６が壁面当接用の突出部を兼用した構成とされている。より具体的には、張り出し部１６の突出高さＨ２は、背面壁部２０の隅部または隅部近傍に設けられた壁面当接用の突出部１７の高さＨ１と同一とされている。筐体Ｃが壁面９に取り付けられた状態においては、張り出し部１６は壁面９に当接し、筐体Ｃの姿勢を安定させる役割、およびパッキン５の圧縮量を規定する役割を果たすようになっている。本実施形態によれば、張り出し部１６の近傍に、壁面当接用の突出部を別途設
