図１に示すように、リモコンＡの操作対象となる空気調和機Ｂは、室内機Ｃと室外機Ｄとを接続配管Ｅで接続し、所望の冷房，暖房，除湿の運転により、室内の温度等を調節する。室内機Ｃは、熱交換機、送風ファン、受信回路などを前面パネルＣ１内に内蔵している。また、室内機Ｃの前面パネルＣ１には、空気の吹き出し口Ｃ２の隣に、リモコンＡとの無線通信を行うための受光部Ｃ３と、運転状態を表示する表示部Ｃ４とを設けている。 As shown in FIG. 1, an air conditioner B to be operated by a remote controller A connects an indoor unit C and an outdoor unit D with a connection pipe E, and performs a desired cooling, heating, and dehumidifying operation to perform indoor temperature control. And so on. The indoor unit C has a heat exchanger, a blower fan, a receiving circuit, and the like built in the front panel C1. Further, on the front panel C1 of the indoor unit C, a light receiving section C3 for performing wireless communication with the remote controller A and a display section C4 for displaying the operating state are provided next to the air outlet C2.

室内機Ｃは、内部の制御基板に実装された該受信回路やマイクロコンピュータを用いて、リモコンＡからの信号に従って、送風ファンや吹き出し口Ｃ２の風向きなどの駆動制御や熱交換機を有する室外機Ｄとの通信を行う。室外機Ｄは、該通信に従って、内蔵する熱交換機を作動させ、室内機Ｃ内の熱交換機の作用を併せて、室内の温度や湿度を空調運転できる。 The indoor unit C uses the receiving circuit and the microcomputer mounted on an internal control board, and according to a signal from the remote controller A, an outdoor unit D having a drive control such as a blower fan and a wind direction of the outlet C2, and a heat exchanger. Communicate with. In accordance with the communication, the outdoor unit D operates the built-in heat exchanger to combine the actions of the heat exchanger in the indoor unit C and can perform the air conditioning operation of the temperature and humidity in the room.

リモコンＡは、液晶表示素子を用いた表示パネル１と、操作ボタン２と、これらを保持するケース３とを備えている。空気調和機Ｂの利用者は、ケース３を手元に把持した状態で、運転切替や所望の温度、風量などを、表示パネル１に表示される空気調和機Ｂの設定状態を確認しながら、操作ボタン２を指先で押圧操作できる。また、リモコンＡは、無線通信手段を備えており、該押圧操作に基づく信号を室内機Ｃの受信回路へ伝えることができる。 The remote controller A includes a display panel 1 using a liquid crystal display element, operation buttons 2, and a case 3 holding these. The user of the air conditioner B operates the operation mode while holding the case 3 at hand while confirming the setting state of the air conditioner B displayed on the display panel 1, such as operation switching and desired temperature and air volume. The button 2 can be pressed with a fingertip. Further, the remote controller A includes a wireless communication unit and can transmit a signal based on the pressing operation to the receiving circuit of the indoor unit C.

次に、リモコンＡについて、図２を用いて説明する。 Next, the remote controller A will be described with reference to FIG.

リモコンＡは、表示パネル１と、操作ボタン２と、ケース３と、回路基板４と、電池収容部５と、を備えている。 The remote controller A includes a display panel 1, operation buttons 2, a case 3, a circuit board 4, and a battery housing section 5.

表示パネル１は、ケース３の開口窓から臨むことができるように保持され、液晶表示素子を適用できる。表示パネル１は、回路基板４に実装された制御回路４１からの制御信号によって駆動制御され、操作ボタン２の操作に基づく、操作状態や、通信対象である空気調和機Ｂの設定状態、室温や現在温度、時刻などを表示できる。また、表示パネル１の表面にタッチパネルを積層することによって、入力手段とすることも考えられる。表示パネル１は、回路基板４に対して図示しない異方性導電部材を介して電気的に接続されるが、フレキシブル配線等を用いて接続することもできる。 The display panel 1 is held so that it can be seen from the opening window of the case 3, and a liquid crystal display element can be applied. The display panel 1 is drive-controlled by a control signal from the control circuit 41 mounted on the circuit board 4, and is operated based on the operation of the operation button 2, the set state of the air conditioner B to be communicated, the room temperature, The current temperature and time can be displayed. It is also conceivable that a touch panel is laminated on the surface of the display panel 1 to serve as an input unit. The display panel 1 is electrically connected to the circuit board 4 via an anisotropic conductive member (not shown), but may be connected using a flexible wiring or the like.

操作ボタン２は、利用者が指先で押圧操作することで、回路基板４に実装されるスイッチ（接点）の通電状態を切り替えるものであり、この場合、合成ゴムやシリコンゴムを適用でき、材質や形状による弾性変形可能な電気絶縁性のシートに、先端面に導電材を有する複数凸部２１を設ける形状である。 The operation button 2 switches the energization state of a switch (contact) mounted on the circuit board 4 when the user presses it with a fingertip. In this case, synthetic rubber or silicon rubber can be applied, and the material and This is a shape in which a plurality of convex portions 21 having a conductive material on the tip surface are provided on an electrically insulating sheet that is elastically deformable depending on the shape.

この凸部２１は、回路基板４の各接点４ａ（図３に示す）に対向し、外側からの押圧操作時に対象の接点４ａに接触することで、通電信号（操作信号）を制御回路４１へ出力できる。また、指先が操作ボタン２から離れた場合には、合成ゴムの形状復帰によって接点４ａを断線（非通電）状態に戻すことができる。 The convex portion 21 faces each contact 4a (shown in FIG. 3) of the circuit board 4 and contacts the contact 4a of the target at the time of the pressing operation from the outside, so that the energization signal (operation signal) is sent to the control circuit 41. Can be output. Further, when the fingertip is separated from the operation button 2, the contact point 4a can be returned to the broken (non-energized) state by restoring the shape of the synthetic rubber.

ケース３は、合成樹脂材からなり、表ケース３１と、裏ケース３２と、蓋３３と、を設けており、これらが組み付けられることで、内部に回路基板４や電池収容部５などの部品を収容する空間を形成する。 The case 3 is made of a synthetic resin material, and is provided with a front case 31, a back case 32, and a lid 33. By assembling these, parts such as the circuit board 4 and the battery accommodating portion 5 are internally provided. Form a space to house.

表ケース３１は、表示パネル１及び操作ボタン２を臨む開口窓３１ａを複数有し、この開口窓３１ａの縁部分によって、表示パネル１及び操作ボタンスイッチ２を位置決めできる。また、表ケース３１は、回路基板４との間に前記異方性導電部材を介して表示パネル１を挟み込むようにして保持するとともに、操作ボタン２も回路基板４との間に挟み込むようにして保持される。回路基板４は、表ケース３１に対して図示しないビスによって固定される。 The front case 31 has a plurality of opening windows 31a facing the display panel 1 and the operation buttons 2, and the edge portion of the opening windows 31a allows the display panel 1 and the operation button switches 2 to be positioned. The front case 31 holds the display panel 1 so as to be sandwiched between the front panel 31 and the circuit board 4 via the anisotropic conductive member, and the operation button 2 is also sandwiched between the operation case 2 and the circuit board 4. Retained. The circuit board 4 is fixed to the front case 31 with screws (not shown).

裏ケース３２は、凹形状に形成され、表ケース３１に対して嵌め込まれ、更に図示しないビスやフックによって固定保持される。また、裏ケース３２は、透光部３２ａと、開口部３２ｂと、当接部３２ｃと、突出壁３２ｄとが形成される。 The back case 32 is formed in a concave shape, is fitted into the front case 31, and is fixedly held by screws and hooks (not shown). Further, the back case 32 is formed with a transparent portion 32a, an opening 32b, an abutting portion 32c, and a protruding wall 32d.

透光部３２ａは、赤外光線を透過可能な透光性の合成樹脂材を適用でき、この場合、透明材に暗色の顔料を混入してから樹脂成形した所謂スモーク部材であり、裏ケース３２に圧入して嵌め込まれる。 A transparent synthetic resin material capable of transmitting infrared rays can be applied to the transparent portion 32a. In this case, the transparent case is a so-called smoke member formed by mixing a transparent pigment with a dark color pigment, and the back case 32. It is press-fitted into and fitted.

開口部３２ｂは、乾電池Ｆを着脱可能なようにケース３内を臨む貫通孔であり、電池収容部５の形状に対応して設けられる。また、裏ケース３２は、電池収容部５の開口端部５１に当たる当接部３２ｃと、開口端部５１の周囲を囲むように設けられる突出壁３２ｄとが形成される。 The opening 32 b is a through hole that faces the inside of the case 3 so that the dry battery F can be attached and detached, and is provided corresponding to the shape of the battery accommodating portion 5. Further, the back case 32 is formed with an abutting portion 32c that abuts the opening end portion 51 of the battery accommodating portion 5, and a protruding wall 32d that is provided so as to surround the periphery of the opening end portion 51.

蓋３３は、裏ケース３２の開口部３２ｂの外側に、この開口部３２ｂを覆い塞ぐように設けられ、電池収容部５と、裏ケース３２の開口部３２ｂとともに、乾電池Ｆの収容空間を形成する。この場合、蓋３３は、弾性変形可能な図示しないフック部を有しており、裏ケース３２に係合保持される。 The lid 33 is provided outside the opening 32b of the back case 32 so as to cover and close the opening 32b, and together with the battery housing 5 and the opening 32b of the back case 32 forms a housing space for the dry battery F. .. In this case, the lid 33 has a hook portion (not shown) that is elastically deformable, and is engaged and held by the back case 32.

また、蓋３３は、電池収容部５に対向する面を凹面とする凹形状に形成されており、リモコンＡの表側（表示パネル１や操作ボタン２を有する面側）を上にして置かれた状態で、乾電池Ｆから内部の電解液が漏れた場合に、この液をある程度留めておくスペースにできるため、回路基板４側へ液が至り難くなる。 The lid 33 is formed in a concave shape with the surface facing the battery accommodating portion 5 as a concave surface, and is placed with the front side (the surface side having the display panel 1 and the operation buttons 2) of the remote controller A facing upward. In this state, when the internal electrolytic solution leaks from the dry battery F, a space can be provided to hold this solution to some extent, so that the solution does not easily reach the circuit board 4 side.

回路基板４は、ガラスエポキシ樹脂等を用いた基材に、銅箔パターンを形成した硬質のプリント基板を適用でき、マイクロコンピュータからなる制御回路４１や、発光ダイオード４２、コンデンサや抵抗素子などの電子部品やスイッチ用の接点４ａ、これらを接続する配線パターンが設けられる。また、回路基板４は、電池収容部５の接触端子５ａや該配線パターンを介して、乾電池Ｆからの電力を発光ダイオード４２などの電子部品に供給できる。 As the circuit board 4, a hard printed board having a copper foil pattern formed on a base material made of glass epoxy resin or the like can be applied, and a control circuit 41 including a microcomputer, a light emitting diode 42, an electronic device such as a capacitor or a resistance element, etc. Contact points 4a for parts and switches, and a wiring pattern for connecting these are provided. Further, the circuit board 4 can supply electric power from the dry battery F to electronic components such as the light emitting diode 42 via the contact terminals 5a of the battery housing portion 5 and the wiring pattern.

なお、この場合、空気調和機Ｂとの通信手段として、赤外光を適用し、出力手段となる発光ダイオード４２による発光パターンによって識別可能な信号をやり取りするが、この他に、例えば、送受信アンテナや電波送受信回路等からなる出力手段をリモコンＡと空気調和機Ｂのそれぞれに用意して、近距離電波信号を利用した通信手段に置き換えることもできる。 In this case, infrared light is applied as the communication means with the air conditioner B, and signals that can be identified by the light emission pattern of the light emitting diode 42 serving as the output means are exchanged. It is also possible to prepare output means including a radio wave transmission/reception circuit for each of the remote controller A and the air conditioner B, and replace them with communication means using short-range radio wave signals.

また、この場合、スイッチ用に操作ボタン２の凸部２１に対向する銅箔パターンからなる接点４ａを複数設ける構造であるが、タクトスイッチなどのスイッチ素子を回路基板４に実装することで代替して適用することもできる。 Further, in this case, a structure is provided in which a plurality of contacts 4a made of a copper foil pattern facing the convex portion 21 of the operation button 2 are provided for the switch, but a switch element such as a tact switch is mounted on the circuit board 4 to replace it. Can also be applied.

電池収容部５は、合成樹脂材を適用でき、開口端部５１と、底壁５２、側壁５３、仕切り壁５４、端子保持部５５とを有し、一面を開口する箱状の乾電池収容ボックスである。電池収容部５は、回路基板４と裏ケース３２とで挟み込むようにして位置決め保持される。 The battery accommodating part 5 is a box-shaped dry battery accommodating box having an open end 51, a bottom wall 52, a side wall 53, a partition wall 54, and a terminal holding part 55, and one side of which is open. is there. The battery housing portion 5 is positioned and held so as to be sandwiched between the circuit board 4 and the back case 32.

また、電池収容部５の底壁５２と側壁５３と仕切り壁５４は、それぞれ貫通孔などなく、互いに水密に結合している。従って、開口端部５１を上にして水平状態にした場合、ある程度の容量分の液溜まり可能な形状としている。端子保持部５５は、底壁５２と側壁５３とによって囲われる箱内において、乾電池Ｆの各電極（陰極または陽極）と接触する接触端子５ａが嵌まる溝形状に形成される。 Further, the bottom wall 52, the side wall 53 and the partition wall 54 of the battery accommodating portion 5 are watertightly coupled to each other without a through hole or the like. Therefore, when the opening end portion 51 is in the horizontal state with the top end facing upward, the shape is such that a certain amount of liquid can be accumulated. The terminal holding portion 55 is formed in a box shape surrounded by the bottom wall 52 and the side wall 53, and has a groove shape into which the contact terminal 5a that contacts each electrode (cathode or anode) of the dry battery F fits.

なお、接触端子５ａは、対向する側壁５３の開口端部５１側から電池収容部５の外側に引き回され、回路基板４に半田接続される。この場合、電池収容部５は、底壁５２からの図示しない突起と、これを挿通する回路基板４の貫通孔とによって、位置決めするとともに、回路基板４に半田接続された接触端子５ａを端子保持部５５に嵌めることで、裏ケース３２が組み付けられるまでの仮止め状態にできる。 The contact terminals 5a are routed from the opening end 51 side of the opposing side wall 53 to the outside of the battery accommodating portion 5 and solder-connected to the circuit board 4. In this case, the battery accommodating portion 5 is positioned by the protrusion (not shown) from the bottom wall 52 and the through hole of the circuit board 4 which is inserted therethrough, and holds the contact terminal 5a solder-connected to the circuit board 4. By fitting the back case 32, the back case 32 can be temporarily fixed until it is assembled.

次に図３を用いて、乾電池Ｆの収容空間について説明する。 Next, the accommodation space of the dry battery F will be described with reference to FIG.

乾電池Ｆの収容空間は、電池収容部５と、裏ケース３２の開口部３２ｂと、蓋３３とによって囲われて設けられる。電池収容部５の開口端部５１は、これに対向する裏ケース３２の当接部３２ｃと当接している。また、この当接箇所において、開口部３２ｂと側壁５３の内壁側とが、段差なく当接している。従って、電池収容部５内に乾電池Ｆの電解液が液漏れした状態で、リモコンＡが表裏に返されても留まりなく底壁５２または蓋３３の内側へ流動される。このため、電解液が、回路基板４や、これに実装される電子部品へ至り難い構造となる。 The storage space for the dry battery F is provided so as to be surrounded by the battery storage portion 5, the opening 32b of the back case 32, and the lid 33. The open end portion 51 of the battery accommodating portion 5 is in contact with the contact portion 32c of the back case 32 that faces the open end portion 51. Further, at this contact point, the opening 32b and the inner wall side of the side wall 53 are in contact with each other without a step. Therefore, when the electrolytic solution of the dry battery F leaks into the battery accommodating portion 5, even if the remote controller A is returned to the front and back, the remote controller A does not stay and flows to the inside of the bottom wall 52 or the lid 33. Therefore, the electrolytic solution has a structure that does not easily reach the circuit board 4 and the electronic components mounted thereon.

また、側壁５３は、底壁５２から、乾電池Ｆの円筒部分の外径の略半分の高さに開口端部５１（当接部３２ｃとの当接箇所）が形成されるように寸法設計されており、リモコンＡが表裏に何れかの状態で放置され、更に乾電池Ｆから電解液が液漏れした場合を想定し、表裏両方の場合であっても、電解液から開口端部５１と当接部３２ｃとの当接面（隙間）までの距離を確保でき、この当接面から電解液が回路基板４側へ浸出することを抑止できる。また、リモコンＡが多少傾いた場合であっても該当接面から電解液が漏れ難い寸法設計となる。 In addition, the side wall 53 is dimensioned so that the opening end portion 51 (contact portion with the contact portion 32c) is formed from the bottom wall 52 at a height approximately half the outer diameter of the cylindrical portion of the dry battery F. Assuming a case where the remote control A is left on either the front surface or the rear surface and the electrolytic solution leaks from the dry battery F, the open end portion 51 contacts the open end portion 51 from the electrolytic solution even in both cases. The distance to the contact surface (gap) with the portion 32c can be secured, and the electrolyte can be prevented from leaching from this contact surface to the circuit board 4 side. Further, even if the remote controller A is slightly tilted, the electrolytic solution does not easily leak from the contact surface.

また、裏ケース３２には、開口端部５１の周りを囲うように枠状に形成される突出壁３２ｄが形成されている。これにより、当接部３２ｃと開口端部５１との微小な隙間から、上記乾電池Ｆの収容空間外へ該電解液が漏れ出た場合にあっても、電解液の拡散を抑止する作用があり、例えば、回路基板４の制御回路４１側へ該液が至りにくくなる。 Further, the back case 32 is formed with a protruding wall 32d formed in a frame shape so as to surround the opening end portion 51. As a result, even if the electrolytic solution leaks out of the accommodation space of the dry battery F through the minute gap between the contact portion 32c and the open end portion 51, there is an action of suppressing the diffusion of the electrolytic solution. For example, it becomes difficult for the liquid to reach the control circuit 41 side of the circuit board 4.

斯かるリモコンＡは、操作ボタン２と、この操作ボタン２の作動に基づいて無線信号を出力する発光ダイオード４２を実装する回路基板４と、この回路基板４に接続され、発光ダイオード４２へ駆動電力を供給するための乾電池Ｆを着脱可能に保持する電池収容部５と、回路基板４及び電池収容部５を内蔵するケース３と、を備えたリモコンＡであって、電池収容部５は、一面を開口する箱状で、底壁５２及び側壁５３が水密に形成される。 The remote controller A is connected to the operation button 2, a circuit board 4 on which a light emitting diode 42 that outputs a radio signal based on the operation of the operation button 2 is mounted, and is connected to the circuit board 4 to drive power to the light emitting diode 42. A battery accommodating portion 5 for detachably holding a dry battery F for supplying the battery, and a case 3 having the circuit board 4 and the battery accommodating portion 5 built therein. The bottom wall 52 and the side wall 53 are formed in a watertight manner.

従って、リモコンＡが表面を下にした状態（表示パネル１や操作ボタン２を下に伏せた状態）で放置され、この間に、乾電池（バッテリ）Ｆの液漏れが生じた場合、該液が回路基板４に至らないため、液漏れに対しても影響を受けにくい遠隔操作装置となる。 Therefore, if the remote control A is left with the surface thereof facing down (the display panel 1 and the operation buttons 2 are faced down), and if liquid leakage of the dry battery (battery) F occurs during this period, the liquid is discharged from the circuit. Since it does not reach the substrate 4, the remote control device is less susceptible to liquid leakage.

また、ケース３は、電池収容部５の開口位置に対応する開口部３２ｂと、この開口部３２ｂと電池収容部５の開口端部５１とが内側に段差なく当接する当接部３２ｃと、を設けることによって、乾電池Ｆが液漏れした場合に、電解液が開口端部５１と当接部３２ｃとの間に至りにくい構造となる。 Further, the case 3 has an opening 32b corresponding to the opening position of the battery accommodating portion 5, and an abutting portion 32c with which the opening 32b and the opening end 51 of the battery accommodating portion 5 abut inward without steps. By providing the structure, when the dry battery F leaks, the electrolytic solution does not easily reach between the open end portion 51 and the contact portion 32c.

また、操作ボタン２は、表ケース３１（ケース３）と回路基板４とで挟み込まれる箇所に、回路基板４に対向して接触する当接面２２が、凸部２１を囲うように設けられる。この当接面２２は、回路基板４面に接することで、回路基板４の接点４ａの周囲を囲うパッキンとして作用し、乾電池Ｆが液漏れした場合に、電解液が接点４ａに至りにくい構造となるため、液漏れによる故障の発生を抑止できる。 Further, the operation button 2 is provided at a portion sandwiched between the front case 31 (case 3) and the circuit board 4 so that a contact surface 22 facing and contacting the circuit board 4 surrounds the convex portion 21. By contacting the surface of the circuit board 4, the contact surface 22 acts as a packing surrounding the contact 4a of the circuit board 4, and when the dry battery F leaks, the electrolytic solution does not easily reach the contact 4a. Therefore, it is possible to suppress the occurrence of a failure due to liquid leakage.
