Description

【0001】
【発明の属する技術分野】
本発明は、給湯器等を制御するリモートコントローラ(以下、リモコンと呼ぶ)に関するものである。
【0002】
【従来の技術】
従来この種のリモコンは、図8から図10に示すような構造のものがあり、リモコン本体に内蔵され風呂の沸き上がり完了などの運転状況を報知するための音源であるブザーの音が、近年の省電力化のため音源の出力を上げられない中、リモコン外部に大きく聞こえるように様々な工夫が施されている。以下その構造を図を参照しながら説明する。
【0003】
図8は従来の構造のリモコンの一例を示す破砕断面図である。図に示すように、このリモコンは上部ケース1と下部ケース2より本体が形成されており、その内部には電子部品や回路を搭載した上部基板3と下部基板4の2枚のプリント基板が内蔵されている。音源である円筒状のブザー5は外部に報知音が届きやすいように上部基板3に搭載され、加えて上部ケース1のブザー5に近接する部分に音穴6が設けられている。
【0004】
図9は従来の構造のリモコンの他の一例である。なお、従来例1と同一構造の部品には同一番号を付し詳細な説明を省略する。基本的な構造は従来例1と同一であるが、プリント基板は下部基板4の一枚となってブザー5を含む全ての部品が下部基板4に搭載されリモコンが薄型化されている。
【0005】
図10は同じく他の従来例のリモコンのブザー5周りの破砕断面図であるが、上部ケース1だけではなく銘板7にも音穴8が設けられ、リモコン外部に音を漏らして大きく聞こえるような構成となっている。
【0006】
【発明が解決しようとする課題】
しかしながら上記従来のリモコンでは、音源をリモコン表面に近接させるためプリント基板を2枚とし上部の基板に搭載する必要が有り、リモコンの薄型化ができないと言う課題があった。またプリント基板を一枚とした場合、音源はリモコン表面から離れるため、音の振動エネルギー(図中に矢印で示す)がリモコン内部に拡散してしまいリモコンより外部に発する音が小さくなってしまうという課題があった。
【0007】
さらに銘板に音穴をあけるという方策では、リモコンの気密性が保たれないため高湿度雰囲気である浴室で使えないと言う課題があった。
【0008】
【課題を解決するための手段】
本発明は上記課題を解決するために、上部ケースと下部ケースとから形成されるリモコン本体と、このリモコン本体の下部ケースの内底面に沿って設け、電子部品を配線した一 枚のプリント基板に取り付けられ、運転状況を報知する音源と、前記音源を内蔵するリモコン本体内部に前記音源の周囲を音源の外周形状に沿って取り囲むように前記上部ケースの裏面に配設し、前記音源の音エネルギーが前記リモコン本体内で拡散するのを防ぎ該音源の対向する前記上部ケース方向へ集中させる筒状の内壁と、前記音源に対向する前記上部ケースの部分の音穴を覆って前記上部ケース表面に設けた銘板を備え、前記内壁は切り欠きを設け浴室リモコンである。
【0009】
上記発明によればリモコン内部に設けられた内壁が音源から発せられる音の振動エネルギーがリモコン内部に拡散するのを防ぐため、リモコンから外部に発する音源の音が大きくなる。よって音源をリモコン表面に近接させる必要が無くリモコンのプリント基板を1枚にでき、リモコン本体の薄型化が可能となる。また銘板にも音穴を開ける必要が無く、浴室用のリモコンにも適用できる。また、音の拡散を防ぐ効果を保ったまま内壁と他の電子部品の干渉を避けられ、比較的自由にプリント基板上に音源を配設することが可能となる。
【0010】
【発明の実施の形態】
本発明の浴室リモコンでは、上部ケースと下部ケースから形成されるリモコン本体と、このリモコン本体の下部ケースの内底面に沿って設け、電子部品を配線した一枚のプリント基板に取り付けられ、運転状況を報知する音源と、前記音源の周囲を該音源の外周形状に沿って取り囲むように前記上部ケースの裏面に配設し、前記音源の音エネルギーが前記リモコン本体内で拡散するのを防ぎ該音源の対向する前記上部ケース方向へ集中させる筒状の内壁と、前記音源に対向する前記上部ケースの部分の音穴を覆って前記上部ケース表面に設けた銘板を備え、前記内壁は切り欠きを設けたものである。
【0011】
そしてリモコン本体内部に設けられた前記音源の周囲を取り囲んで配設した筒状の内壁が、音源から発せられる音の振動エネルギーがリモコン内部に拡散するのを防ぎ正面の音穴に集中させるため、リモコンより外部に発する音が大きくなる。また音源をリモコン表面に近接させる必要が無くリモコンのプリント基板を1枚にでき、結果リモコン本体の薄型化が可能となる。加えて銘板に音穴を開ける必要が無く、リモコン内部の気密性を保持することができ、高湿度雰囲気である浴室でも使用できる。
【0012】
また、音源の周囲を取り囲んで配設した筒状の内壁に切り欠きを入れたものである。そして内壁に切り欠きを有するため、音の拡散を防ぐ効果を保ったまま内壁と他の電子部品の干渉を避けることができ、比較的自由にプリント基板上に音源を配設することが可能となる。
【0013】
【実施例】
以下、本発明の実施例について、図面を用いて説明する。
【0014】
(実施例1)
図1から図3に本発明の実施例1を示す。図1は本発明の実施例1のリモコンの構造を示す破砕断面図である。また図2はその分解構造図、図3はリモコンを正面より見た、音源周りの破砕断面図である。なお、従来例と同一構造の部品には同一番号を付して詳細な説明を省略する。
【0015】
図に示すように、このリモコンは上部ケース1と下部ケース2より本体が形成されている。上部ケース1は液晶表示部9の表示窓10、電池収納部11、スイッチ12まで伸びたスイッチボス13などより構成され、そして音穴6が正面に開けられその音穴6よりプリント基板14に搭載された音源5の周囲を取り囲むように内壁15が伸びている。また上部ケース1の正面には、リモコンのスイッチボタン16が付いた銘板7が貼り付けられている。プリント基板14は一枚で構成されその上には音源5、液晶表示部9、スイッチ12、給湯器本体と交信するための通信モジュール17などが搭載されている。
【0016】
次にその動作と作用について説明する。リモコン本体に内蔵されたブザー5は、使用者がリモコンのスイッチボタン16を押してプリント基板14上のスイッチ12を開閉し電気回路を作動させたときに、音を発生して使用者に報知したり、給湯器本体から通信モジュール17を介して受け取った運転情報、例えば風呂の沸き上がり完了などの運転状況を報知する。当然このブザーの音はリモコンから離れていても使用者に良く聞こえるため音量が大きいほど好ましい。本実施例では、上部ケース1の正面側に音穴6が開けられ、その音穴6よりプリント基板14に搭載された音源5の周囲を取り囲むように円筒状の内壁15が伸びている。音源のブザー5が報知音を発生すると、この内壁15が音の振動エネルギーをリモコン内部に拡散し内部で減衰するのを防ぎ音穴6のある正面方向に集中させるため、リモコン正面より外部に発する報知音が大きくなる。
【0017】
以上の作用より、音源をリモコン表面に近接させる必要が無くリモコンのプリント基板を1枚にでき、結果リモコン本体の薄型化が可能となる。また銘板7に音穴を開ける必要が無く、リモコン内部の気密性を保持することができ、高湿度雰囲気である浴室でも使用できる。
【0018】
(実施例2)
図4から図6に本発明の実施例2を示す。図4は本発明の実施例2のリモコンの構造を示す破砕断面図である。また図5はその分解構造図、図6はリモコンを正面より見た、音源周りの破砕断面図である。なお、実施例1と同一構造の部品には同一番号を付して詳細な説明を省略する。本実施例のリモコンの構造は前記実施例1とほぼ同一であるが、プリント基板14上に他の電子部品18が搭載され、ブザー5がスイッチ13側に寄せられて配置させられている。そしてブザー5の周囲を取り囲んで配せられた筒状の内壁15に切り欠き19を有するため、音の拡散を防ぐ効果を保ったまま内壁15と他の電子部品18やスイッチ13との干渉を避けることができ、比較的自由にプリント基板上に音源を配置することが可能となる。
【0019】
図7に本発明におけるリモコンの外部に発生されるブザーの音圧を測定した時の測定条件を模式的に示す。測定は外部からの雑音や反響が無い無響室内で室温を20℃に保って行われ、リモコン20をリモコン取付台21に床面22より1mの高さで固定し、音圧測定用の集音マイク23を同じ高さでリモコン20より1mの距離をおいて測定した。
【0020】
例えば本実施例のリモコンでは、可聴域である周波数約2kHz域で約60dBの音圧であった。一方、比較のためブザー5や電子部品やリモコンケース1、2の構造は同じで内壁15が無いだけのリモコン(従来例2、図9を参照)の音圧の測定を行ったが、周波数約2kHz域で約54dBの音圧であった。
【0021】
以上の結果から本実施例ではブザー5の周囲を取り囲んでリモコンの前面の音穴6まで伸びる内壁15が、リモコン外部に発する音圧を約6dB向上させた。
【0022】
なお、本発明では内壁15の形状をブザー5の形状に合わせて円筒形としているが、音源の形状に合わせた形状にすれば同様の効果が得られる。
【0023】
また本発明では上部ケース1に音穴6を設けているが、音穴を設けなくても音の振動エネルギーの抵抗インピーダンスは銘板と変わらないので同様の効果がある。
【0024】
また、本発明では音源をブザーとしたが、スピーカーなど他の種類の音源でも同様に実施することができる。
【0025】
また本発明では給湯器を制御するリモコンに実施したが、音源を内蔵するケース構造物、例えば家庭機器のリモコンや携帯電話などでも同様に実施することができる。
【0026】
【発明の効果】
以上の説明から明らかなように、本発明の浴室リモコン構造によれば以下のような効果が得られる。
【0027】
(1)上部ケースと下部ケースから形成されるリモコン本体と、このリモコン本体の下部ケースの内底面に沿って設け、電子部品を配線した一枚のプリント基板に取り付けられ、運転状況を報知する音源と、リモコン本体内部に音源の周囲を該音源の外周形状に沿って取り囲むように前記上部ケースの裏面に配設し、前記音源の音エネルギーが前記リモコン本体内で拡散するのを防ぎ該音源の対向する前記上部ケース方向へ集中させる筒状の内壁と、前記音源に対向する前記上部ケースの部分の音穴を覆って前記上部ケース表面に設けた銘板を備え、前記内壁は切り欠きを設けた構造としているので、この内壁が音源から発せられる音の振動エネルギーがリモコン内部に拡散し減衰するのを防ぎ、音穴のある正面方向に集中させるため、リモコン正面より外部に発する報知音を大きくすることができる。
【0028】
また音源をリモコン表面に近接させる必要が無くリモコンのプリント基板を1枚にでき、結果リモコン本体の薄型化が可能となる。加えて銘板に音穴を開ける必要が無く、リモコン内部の気密性を保持することができ、高湿度雰囲気である浴室でも使用できる。
【0029】
(2)音源の周囲を取り囲んで配せられた内壁に切り欠きを有するため、音の拡散を防ぐ効果を保ったまま内壁と他の電子部品の干渉を避けることができ、比較的自由にプリント基板上に音源を配置することが可能となる。

[0013]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0014]
(Example 1)
1 to 3 show a first embodiment of the present invention. FIG. 1 is a crushed cross-sectional view showing the structure of the remote control according to the first embodiment of the present invention. 2 is an exploded structural view thereof, and FIG. 3 is a cross-sectional view around the sound source when the remote controller is viewed from the front. In addition, the same number is attached | subjected to the components of the same structure as a prior art example, and detailed description is abbreviate | omitted.
[0015]
As shown in the figure, the remote control has a main body formed of an upper case 1 and a lower case 2. The upper case 1 is composed of a display window 10 of the liquid crystal display unit 9, a battery storage unit 11, a switch boss 13 extending to the switch 12, and the like, and a sound hole 6 is opened in the front and mounted on the printed circuit board 14 from the sound hole 6. The inner wall 15 extends so as to surround the periphery of the generated sound source 5. A nameplate 7 with a remote control switch button 16 is attached to the front of the upper case 1. The printed circuit board 14 is composed of a single sheet, on which a sound source 5, a liquid crystal display unit 9, a switch 12, a communication module 17 for communicating with the water heater body, and the like are mounted.
[0016]
Next, the operation and action will be described. The buzzer 5 built in the remote control body generates a sound when the user presses the switch button 16 on the remote control to open and close the switch 12 on the printed circuit board 14 to activate the electric circuit, and notifies the user. The operation information received from the main body of the water heater via the communication module 17, for example, the operation status such as the completion of boiling of the bath is notified. Of course, since the buzzer sounds well to the user even if it is away from the remote control, it is preferable that the volume is high. In this embodiment, a sound hole 6 is formed on the front side of the upper case 1, and a cylindrical inner wall 15 extends from the sound hole 6 so as to surround the periphery of the sound source 5 mounted on the printed circuit board 14. When the buzzer 5 of the sound source generates a notification sound, the inner wall 15 emits the vibration energy of the sound inside the remote control and prevents the sound from being attenuated inside, so that the sound is emitted from the front of the remote control to the outside. The notification sound increases.
[0017]
With the above operation, there is no need to bring the sound source close to the surface of the remote control, and the remote control printed circuit board can be made into one sheet. As a result, the remote control body can be made thin. Further, there is no need to make a sound hole in the nameplate 7, the airtightness inside the remote control can be maintained, and it can be used in a bathroom having a high humidity atmosphere.
[0018]
(Example 2)
4 to 6 show a second embodiment of the present invention. FIG. 4 is a crushed sectional view showing the structure of the remote control according to the second embodiment of the present invention. FIG. 5 is an exploded structural view thereof, and FIG. 6 is a fragmentary sectional view around the sound source when the remote controller is viewed from the front. In addition, the same number is attached | subjected to the components of the same structure as Example 1, and detailed description is abbreviate | omitted. The structure of the remote controller of this embodiment is almost the same as that of the first embodiment, but another electronic component 18 is mounted on the printed circuit board 14 and the buzzer 5 is arranged close to the switch 13 side. Since the cylindrical inner wall 15 arranged so as to surround the buzzer 5 has a notch 19, the interference between the inner wall 15 and other electronic components 18 and the switch 13 can be maintained while maintaining the effect of preventing sound diffusion. The sound source can be arranged on the printed circuit board relatively freely.
[0019]
FIG. 7 schematically shows measurement conditions when the sound pressure of the buzzer generated outside the remote controller in the present invention is measured. The measurement is performed in an anechoic room without external noise and reverberation, and the room temperature is kept at 20 ° C. The remote control 20 is fixed to the remote control mounting base 21 at a height of 1 m from the floor 22 to collect sound pressure. The sound microphone 23 was measured at the same height at a distance of 1 m from the remote control 20.
[0020]
For example, in the remote control of this example, the sound pressure was about 60 dB in the audible frequency range of about 2 kHz. On the other hand, for comparison, the sound pressure of a remote controller (refer to Conventional Example 2 and FIG. 9) having the same structure of the buzzer 5, electronic parts, and remote control cases 1 and 2 but having no inner wall 15 was measured. The sound pressure was about 54 dB in the 2 kHz region.
[0021]
From the above results, in this embodiment, the inner wall 15 surrounding the buzzer 5 and extending to the sound hole 6 on the front surface of the remote control has improved the sound pressure emitted to the outside of the remote control by about 6 dB.
[0022]
In the present invention, the shape of the inner wall 15 is cylindrical according to the shape of the buzzer 5, but the same effect can be obtained if the shape is matched to the shape of the sound source.
[0023]
Moreover, although the sound hole 6 is provided in the upper case 1 in the present invention, the same effect is obtained because the resistance impedance of the vibration energy of the sound is not different from that of the nameplate without providing the sound hole.
[0024]
In the present invention, the sound source is a buzzer, but other types of sound sources such as speakers can be similarly implemented.
[0025]
In the present invention, the present invention is applied to a remote controller for controlling a water heater. However, the present invention can be similarly applied to a case structure containing a sound source, for example, a remote controller for a home device or a mobile phone.
[0026]
【The invention's effect】
As is apparent from the above description, the bathroom remote control structure of the present invention provides the following effects.
[0027]
(1) A remote control main body formed of an upper case and a lower case, and a sound source provided along a bottom surface of the lower case of the remote control main body and attached to a single printed circuit board wired with electronic components to notify the driving situation And arranged on the back surface of the upper case so as to surround the sound source in the remote control body along the outer peripheral shape of the sound source to prevent the sound energy of the sound source from diffusing in the remote control body. A cylindrical inner wall that is concentrated in the direction of the upper case facing to each other, and a name plate provided on the surface of the upper case so as to cover a sound hole of a portion of the upper case facing the sound source, the inner wall provided with a notch Because of its structure, the inner wall prevents the vibration energy of sound emitted from the sound source from diffusing and decaying inside the remote control, and concentrates it in the front direction with the sound holes. It is possible to increase the notification sound emanating from down the front to the outside.
[0028]
In addition, there is no need to bring the sound source close to the remote control surface, and the remote control printed circuit board can be made into one sheet. As a result, the remote control body can be made thinner. In addition, there is no need to make a sound hole in the nameplate, the airtightness inside the remote control can be maintained, and it can be used in a bathroom with a high humidity atmosphere.
[0029]
(2) Since there is a notch on the inner wall that surrounds the sound source, interference between the inner wall and other electronic components can be avoided while maintaining the effect of preventing sound diffusion, and printing is relatively free. A sound source can be arranged on the substrate.
