Description

本発明は、音声での報知を行う洗濯機に関する。   The present invention relates to a washing machine that performs voice notification.

従来より操作の案内や警告を音声で行う洗濯機が提案されており、この種の洗濯機の従来例としては、洗濯機外枠の上部に覆うように構成した上カバーと、前記上カバーの衣類投入口の側面を覆うように取り付けたサイドパネルによって構成されるサイドパネルボックス内部にスピーカを設置している（例えば、特許文献１参照）。   Conventionally, a washing machine that performs voice guidance and warning of operation has been proposed, and as a conventional example of this type of washing machine, an upper cover configured to cover the upper part of the outer frame of the washing machine, A speaker is installed inside a side panel box constituted by a side panel attached so as to cover the side surface of the clothing insertion opening (see, for example, Patent Document 1).

図５は、特許文献１に記載された従来の洗濯機を示す一部切り欠き斜視図であり、図６は、同洗濯機のサイドパネルを分解してスピーカ取付状態を示す上カバーの斜視図であり、図７は、同洗濯機のサイドパネル部の拡大斜視図であり、図８は、同洗濯機のスピーカ
と共鳴箱の分解斜視図であり、以下その構成につき説明する。 FIG. 5 is a partially cutaway perspective view showing a conventional washing machine described in Patent Document 1, and FIG. 6 is a perspective view of an upper cover showing a speaker mounting state by disassembling a side panel of the washing machine. FIG. 7 is an enlarged perspective view of a side panel portion of the washing machine, and FIG. 8 is an exploded perspective view of a speaker and a resonance box of the washing machine. The configuration will be described below.

図５において、洗濯機外枠１の上方には開閉自在に配した蓋２０を有する上カバー９を載置し、この上カバー９の前面には操作部１１を配し、左側のサイドパネルボックス４９内部に、スピーカを内蔵した共鳴箱４７を固着している。   In FIG. 5, an upper cover 9 having a lid 20 that can be freely opened and closed is placed above the outer frame 1 of the washing machine, and an operation unit 11 is disposed on the front surface of the upper cover 9 so that the left side panel box A resonance box 47 with a built-in speaker is fixed inside 49.

共鳴箱４７は、図８の分解斜視図に示すように、前面にスピーカ４６の振動板に対向する放音穴４７ａを有し、後面を開放した前側箱４７ｂと、前面を開放し、後面の内側にスピーカ押さえ４７ｃを起立させた後側箱４７ｄによって構成する。   As shown in the exploded perspective view of FIG. 8, the resonance box 47 has a sound emitting hole 47 a facing the diaphragm of the speaker 46 on the front surface, a front box 47 b that opens the rear surface, and a front surface that opens, The speaker holder 47c is erected on the inner side to constitute the rear box 47d.

音声を発するスピーカ４６は、図８に示したように、共鳴箱４７に内蔵した状態で、図６に示すように上カバー９に形成された衣類投入口９ａの側部を覆うように取り付けるサイドパネル４８の内側に形成されるサイドパネルボックス４９内部に設置する。   As shown in FIG. 8, the speaker 46 that emits sound is mounted on the side of the clothing insertion port 9a formed in the upper cover 9 as shown in FIG. It is installed inside a side panel box 49 formed inside the panel 48.

上記のように、スピーカ４６を内蔵した共鳴箱４７は、サイドパネルボックス４９内に納まるように上カバー９上にとりつける。この取付は、共鳴箱４７に形成した取付け鍔４７ｅを上カバー９に形成した取付座にねじ止めすることにより行う。   As described above, the resonance box 47 with the built-in speaker 46 is mounted on the upper cover 9 so as to be accommodated in the side panel box 49. This attachment is performed by screwing an attachment rod 47e formed on the resonance box 47 to an attachment seat formed on the upper cover 9.

一方、サイドパネル４８の垂直な側面には、図７に示すように、排水ホース等を収納するときにフックを引掛けるフック係止穴４８ａを開口させている。スピーカ４６からの音声が機外に放出されるのを大きくする為に、共鳴箱４７の放音穴４７ａは出来るだけ前記フック係止穴４８ａに近くに位置するようにしている。   On the other hand, as shown in FIG. 7, a hook locking hole 48a for hooking a hook when storing a drainage hose or the like is opened on the vertical side surface of the side panel 48. In order to increase the sound emitted from the speaker 46 to the outside of the apparatus, the sound emission hole 47a of the resonance box 47 is positioned as close as possible to the hook locking hole 48a.

スピーカ４６の防湿、防水は共鳴箱４７にてなされるとともに、発生した音声は、サイドパネル４８に形成したフック係止穴４８ａから効率よく機外に放音するという構成である。   The speaker 46 is moisture-proofed and waterproofed in the resonance box 47, and the generated sound is efficiently emitted from the hook locking hole 48a formed in the side panel 48 to the outside of the machine.

なお、上記フック係止穴４８ａを形成しない別の従来例にあっては、機外への放音が少なくなるので、スピーカ４６の仕様等を大型化する事により音声の大きいものを使う事もある。
特開２００２−１１２７４号公報 In another conventional example in which the hook locking hole 48a is not formed, sound emission to the outside of the machine is reduced. Therefore, it is possible to use a louder speaker by increasing the size of the speaker 46 and the like. is there.
JP 2002-11274 A

しかしながら、このような従来の洗濯機の音声報知構成では、スピーカ４６の発生した音声を効率良く機外に報知する為には、スピーカ４６を内蔵した共鳴箱４７を構成する前側箱４７ｂの放音穴４７ａと、サイドパネル４８に形成した音声放出用のフック係止穴４８ａとを出来るだけ直線的に配置したり、近接させたり、またフック係止穴４８ａの形状を大きくする等が必要であった。しかしこれは、例えば洗濯機の外観を掃除する際に濡れたタオル等でふく場合には、前記フック係止穴４８ａより内方に水分が浸入した場合には、直線的な配置や、近接した配置をすればするほど、電気部品であるスピーカへの防水、防湿に悪影響を与える不具合があり、信頼性は十分な構成ではなかった。   However, in such a conventional sound notification configuration of a washing machine, in order to efficiently notify the sound generated by the speaker 46 to the outside of the device, the sound emission of the front box 47b constituting the resonance box 47 incorporating the speaker 46 is emitted. It is necessary to arrange the hole 47a and the hook locking hole 48a for sound emission formed in the side panel 48 in a straight line as close as possible, or to enlarge the shape of the hook locking hole 48a. It was. However, for example, when cleaning the appearance of the washing machine with a wet towel or the like, if moisture enters inward from the hook locking hole 48a, the linear arrangement or proximity As the arrangement is increased, there is a problem that the waterproofing and moisture-proofing of the speaker, which is an electrical component, is adversely affected, and the reliability is not sufficient.

また、かかるフック係止穴のような小孔には、子供が好奇心や悪戯等で指を差し込んだり小棒を差し込んだりすることがあり、放音穴４７ａ部よりスピーカ４６を損傷する事がある。更に、導電性のある小棒等で充電部材であるスピーカ４６に触れる事は感電事故等の危険性もある。   In addition, the small hole such as the hook locking hole may cause a child to insert a finger or a small stick with curiosity or mischief, and the speaker 46 may be damaged from the sound emission hole 47a. is there. Further, touching the speaker 46, which is a charging member, with a conductive rod or the like may cause a risk of electric shock.

近年の洗濯機には、子供が好奇心より、運転中の洗濯機の操作部１１や洗濯物出し入れの蓋２０の部分に触れて誤動作をすることが無い様に、チャイルドロック構成されている
のが一般的である。 In recent washing machines, a child lock is configured so that children do not curiously touch the operation part 11 of the washing machine in operation or the lid 20 part of the laundry in and out to malfunction. Is common.

しかし、洗濯機の操作部１１や蓋２０には子供が悪戯で操作してもチャイルドロック操作にて誤動作防止は出来ても、かかるフック係止穴４８ａのような小孔からの悪戯には上記チャイルドロックは困難であった。   However, the operation unit 11 and the lid 20 of the washing machine can be prevented from malfunctioning by child lock operation even if the child operates mischief. Child lock was difficult.

一方、従来例でも記述したごとく、フック係止穴４８ａの無い仕様にあっては、水分の浸入や上記子供の悪戯等による不具合は解消されても、スピーカの音声が洗濯機外方に伝達され難く、スピーカを大型化しなければならず、また機内のサイドパネルボックス４９内部で音声が篭ってしまい明瞭な聞き取りが困難なものであった。   On the other hand, as described in the conventional example, in the specification without the hook locking hole 48a, the sound of the speaker is transmitted to the outside of the washing machine even if the intrusion of moisture or the above-mentioned child mischief is solved. It was difficult, the speaker had to be increased in size, and the voice squeezed inside the side panel box 49 in the aircraft, making it difficult to hear clearly.

本発明は、上記従来の課題を解決するもので、スピーカへの防水、防湿を高め、子供の好奇心や悪戯等で損傷を受ける危険性が解消され、小型のスピーカでも十分な可聴か可能な洗濯機を提供する事を目的とする。   The present invention solves the above-described conventional problems, improves the waterproofing and moisture-proofing of the speaker, eliminates the risk of being damaged by children's curiosity and mischief, and can be sufficiently audible even with a small speaker. The purpose is to provide a washing machine.

前記従来の課題を解決するために、本発明の洗濯機は、洗濯、すすぎ、脱水等の行程を制御する制御装置と、前記制御装置から音声信号を入力される音声発生のスピーカと、洗濯機外枠と、前記外枠上方を覆う上カバーと、前記上カバーの後部に構成した後方パネル部と、前記後方パネル部を後方から覆う後部カバーとを備え、前記後方パネル部の内部に、両端に上部開口と側面開口とを有する断面略Ｌ字状のケースと、前記断面略Ｌ字状のケースの上部開口に覆設した音声発生のスピーカ取付ケースを固着し、音声発生のスピーカは振動板を下方に向けて前記スピーカ取付ケースに取り付けると共に、断面略Ｌ字状のケースの側面開口は、前記後部カバーに形成した開口より洗濯機後方に指向させ、断面略Ｌ字状のケースの側面開口の周縁にフランジを形成して前記後部カバーに気密的に密着させるようにしたものである。 In order to solve the above-described conventional problems, a washing machine of the present invention includes a control device that controls a process such as washing, rinsing, and dehydration, a sound generation speaker that receives a sound signal from the control device, and a washing machine. An outer frame, an upper cover that covers the upper portion of the outer frame, a rear panel portion that is configured at a rear portion of the upper cover, and a rear cover that covers the rear panel portion from the rear. A case having a substantially L-shaped cross section having an upper opening and a side opening and a sound generating speaker mounting case covering the upper opening of the substantially L-shaped case are fixed to each other, and the sound generating speaker is a diaphragm. The side opening of the case having a substantially L-shaped cross section is directed to the rear of the washing machine from the opening formed in the rear cover, and the side opening of the case having a substantially L-shaped cross section is attached. Rim of Forming a flange is obtained so as to hermetically close contact with the rear cover.

これによって、音声の放音穴からの水の浸入の危険性が減少し、音声発生の振動板（コーン紙）が直接外方に向く構成ではないため、外部からの損傷の恐れが無くなる。   As a result, the risk of water intrusion from the sound emission hole is reduced, and since the sound generating diaphragm (cone paper) is not directly directed outward, there is no risk of damage from the outside.

また、洗濯機の設置状況から洗濯機の後方の家屋壁面での音の反射により、小型のスピーカでも洗濯機前方での可聴音圧は高くできる。   In addition, the audible sound pressure in front of the washing machine can be increased even with a small speaker due to the reflection of sound on the wall of the house behind the washing machine due to the installation state of the washing machine.

本発明の洗濯機の音声報知構成によれば、電気部品であるスピーカの防湿、防水に優れ、子供等の悪戯による不具合の発生を防止でき、小型のスピーカを使用して小さい音声電力で大きい音声報知が出来る。さらに、断面略Ｌ字状のケース周辺からの発した音が、音の伝達経路が異なる事で、後部カバーより後方に位相をずらせて洩れることを防止するので、断面略Ｌ字状のケースの内部を通過した音と位相がずれて干渉により消音あるいは減音をする、という事が発生しない。 According to the voice notification configuration of the washing machine of the present invention, the speaker, which is an electrical component, is excellent in moisture proofing and waterproofing, can prevent the occurrence of malfunctions due to mischief of children, etc., and uses a small speaker to generate large voice with low voice power Announcement is possible. Furthermore, since the sound transmitted from the periphery of the case having a substantially L-shaped cross section is prevented from leaking out of phase behind the rear cover due to a different sound transmission path, the case of the case having a substantially L-shaped cross section is prevented. It does not occur that sound is muted or reduced due to interference due to phase shift from the sound that has passed through the inside.

第１の発明は、洗濯、すすぎ、脱水等の行程を制御する制御装置と、前記制御装置から音声信号を入力される音声発生のスピーカと、洗濯機外枠と、前記外枠上方を覆う上カバーと、前記上カバーの後部に構成した後方パネル部と、前記後方パネル部を後方から覆う後部カバーとを備え、前記後方パネル部の内部に、両端に上部開口と側面開口とを有する断面略Ｌ字状のケースと、前記断面略Ｌ字状のケースの上部開口に覆設した音声発生のスピーカ取付ケースを固着し、音声発生のスピーカは振動板を下方に向けて前記スピーカ取付ケースに取り付けると共に、断面略Ｌ字状のケースの側面開口は、前記後部カバーに形成した開口より洗濯機後方に指向させ、断面略Ｌ字状のケースの側面開口の周縁にフラン
ジを形成して前記後部カバーに気密的に密着させるようにしたことにより、洗濯機後方に放音をさせるので、音声の放音穴からの水の浸入の危険性が減少し、音声発生の振動板（コーン紙）が直接外方に向かないため、外部からの損傷の恐れが無くなる。 According to a first aspect of the present invention, there is provided a control device that controls a process such as washing, rinsing, and dehydration, a sound-generating speaker that receives a sound signal from the control device, an outer frame of the washing machine, and an upper portion that covers the upper portion of the outer frame. A cross section having an upper opening and side openings at both ends inside the rear panel portion, and a rear panel portion configured to cover the rear panel portion from the rear; an L-shaped casing, fixed to the speaker mounting case for sound generation that Kutsugae設the upper opening of the substantially L-shaped cross section of the case, the speaker of the sound generation is attached to the speaker mounting case toward the diaphragm downward In addition, the side opening of the case having a substantially L-shaped cross section is directed toward the rear of the washing machine from the opening formed in the rear cover, and a flange is formed on the periphery of the side opening of the case having a substantially L-shaped cross section.
Since the sound is emitted behind the washing machine by forming a die and making it tightly adhere to the rear cover, the risk of water intrusion from the sound emission hole is reduced, and sound generation is reduced. Since the diaphragm (cone paper) does not face directly outward, there is no risk of external damage.

また、洗濯機の設置状況から洗濯機の後方の家屋壁面での音の反射により、小型のスピーカでも洗濯機前方での報知音圧は高くできる。   Further, the sound pressure at the front of the washing machine can be increased even with a small speaker due to reflection of sound from the wall surface of the house behind the washing machine due to the installation state of the washing machine.

さらに、断面略Ｌ字状のケース周辺からの発した音が、音の伝達経路が異なる事で、後部カバーより後方に位相をずらせて洩れることを防止するので、断面略Ｌ字状のケースの内部を通過した音と位相がずれて干渉により消音あるいは減音をする、という事が発生しない。 Furthermore, since the sound transmitted from the periphery of the case having a substantially L-shaped cross section is prevented from leaking out of phase behind the rear cover due to a different sound transmission path, the case of the case having a substantially L-shaped cross section is prevented. It does not occur that sound is muted or reduced due to interference due to phase shift from the sound that has passed through the inside.

以下、本発明の実施の形態について、図面を参照しながら説明する。従来例と同じ構成のものは同一符号を付して詳細な説明は省略する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Components having the same configurations as those of the conventional example are denoted by the same reference numerals, and detailed description thereof is omitted. Note that the present invention is not limited to the embodiments.

FIG. 4 is a partial cross-sectional view showing a speaker mounting state of the washing machine.

図１の外観斜視図において、洗濯機外枠１の上方には上カバー９を載置するとともに前方に開閉自在に蓋２０を配する。洗濯機外枠１の前面上方には、洗濯機の操作並びに表示を行うパネル２を配し、上カバー９の後部には洗濯水を供給する給水ホース３を配管し、後方の家屋の壁３６等に設置された水道給水蛇口３７に接続する。   In the external perspective view of FIG. 1, an upper cover 9 is placed above the washing machine outer frame 1, and a lid 20 is arranged to be openable and closable forward. A panel 2 for operating and displaying the washing machine is arranged above the front surface of the washing machine outer frame 1, and a water supply hose 3 for supplying washing water is piped at the rear part of the upper cover 9, and the wall 36 of the rear house It connects to the tap water supply faucet 37 installed in etc.

使用者は、蓋２０の開閉により衣類を洗濯機の内部から出し入れすると共に、パネル２により、制御装置への運転信号の入力や、運転状況や設定状況を目視する。このとき、音声により案内や注意等が報知されるので、誤操作も少なく使い勝手の優れた構成となる。   The user takes clothes in and out of the washing machine by opening and closing the lid 20, and also inputs an operation signal to the control device, and visually checks the operation state and the setting state through the panel 2. At this time, since guidance, attention, and the like are notified by voice, the configuration is excellent in usability with few erroneous operations.

図２の後方からの部分外観斜視図に示すように、上カバー９の後方に構成した後方パネル部１０の内部に音声発生のスピーカを配し、その音声を、後部カバー１１に形成した開口１２より後方に放音させるものである。   As shown in a partial external perspective view from the rear of FIG. 2, a sound generating speaker is arranged inside a rear panel portion 10 configured behind the upper cover 9, and the sound is provided in an opening 12 formed in the rear cover 11. The sound is emitted further backward.

図３の制御回路のブロック図に示すように、制御装置１３は、メモリや入出力回路などの周辺回路を組み込んだマイコン１４を主体に構成し、入力スイッチ１５ａ等の入力手段１５からの入力を検知し、洗濯、すすぎ、脱水等の一連の行程を制御する負荷制御手段１６に伝達するとともに、表示手段１７に入力された状態や、行程進行状態等を表示する。   As shown in the block diagram of the control circuit in FIG. 3, the control device 13 is mainly composed of a microcomputer 14 incorporating peripheral circuits such as a memory and an input / output circuit, and receives input from the input means 15 such as an input switch 15a. It detects and transmits to the load control means 16 which controls a series of processes such as washing, rinsing and dehydration, and also displays the state input to the display means 17 and the progress of the process.

負荷制御手段１６は、前記制御装置１３からの信号により、モータ１８ａ等の駆動手段１８の給電制御をする。   The load control means 16 controls the power supply of the drive means 18 such as the motor 18a in accordance with a signal from the control device 13.

音声報知手段１９は、制御装置１３のマイコン１４に予め記憶させた音声ＲＯＭ２１の音声データを読み出し、Ｄ／Ａ変換２２によりアナログ信号として取り出し、ローパスフィルタ２３にて波形を整形した後、アンプ（増幅器）２４からの電気信号をスピーカ２５にて音波に変換するものである。   The voice notification means 19 reads the voice data of the voice ROM 21 stored in advance in the microcomputer 14 of the control device 13, takes out it as an analog signal by the D / A conversion 22, shapes the waveform by the low-pass filter 23, and then an amplifier (amplifier). ) The electrical signal from 24 is converted into sound waves by the speaker 25.

なお、音声報知の内容は、入力手段１５からの情報により、行程のガイド、操作の誘導、異常報知などを行い、使用者の利便性を高めるものである。   Note that the contents of the voice notification enhance the user's convenience by performing a process guide, operation guidance, abnormality notification, and the like based on information from the input means 15.

図４の部分断面図により、スピーカ２５の取付構成を以下説明する。   The mounting configuration of the speaker 25 will be described below with reference to the partial cross-sectional view of FIG.

断面略コ字状のスピーカ取付ケース２７は、コ字の開放部分を下方に向けて配し、前記開放部分に、スピーカ２５をその振動板（コーン紙）２６を下方に向けて取り付ける。   The speaker mounting case 27 having a substantially U-shaped cross section is provided with a U-shaped open portion facing downward, and the speaker 25 is mounted on the open portion with its diaphragm (cone paper) 26 facing downward.

スピーカ取付ケース２７は、例えばプラスチック成型品で構成し周縁部に一体形成したＬ字係止片２９にスピーカ２５の外周部を係着し、略１８０度対向位置に形成した弾性を有するＬ型突起２８の弾性を利用してスピーカ２５の他端外周部を係止する。   The speaker mounting case 27 is made of, for example, a plastic molded product, and an L-shaped protrusion having an elasticity formed at an approximately 180-degree opposed position by engaging the outer peripheral portion of the speaker 25 with an L-shaped locking piece 29 formed integrally with the peripheral portion. The outer peripheral portion of the other end of the speaker 25 is locked using the elasticity of 28.

スピーカ２５を係着したスピーカ取付ケース２７は、上部開口３１と側面開口３２とを有する断面略Ｌ字状のケース３０の、前記上部開口３１に、スピーカ２５の振動板（コーン紙）２６が下方向に指向するように配して、ねじ（図示せず）等で固定する。   The speaker mounting case 27 to which the speaker 25 is attached has a substantially L-shaped cross section 30 having an upper opening 31 and a side opening 32, and a diaphragm (cone paper) 26 of the speaker 25 is placed below the upper opening 31. Arrange it so that it points in the direction and fix it with screws (not shown).

よって、スピーカ２５は略水平に保持されるので、振動板（コーン紙）２６は、断面略Ｌ字状のケース３０の側面開口３２とは角度を略９０度傾斜した構成となる。   Therefore, since the speaker 25 is held substantially horizontally, the diaphragm (cone paper) 26 is configured to be inclined at an angle of approximately 90 degrees with respect to the side opening 32 of the case 30 having a substantially L-shaped cross section.

スピーカ２５を係着したスピーカ取付ケース２７を組み込んだ断面略Ｌ字状のケース３０は、洗濯機の外枠１上方に載置された上カバー９の後方に構成した後方パネル部１０の内部に、放音穴となる側面開口３２が洗濯機の後方を指向するように配置する。   A case 30 having a substantially L-shaped cross section incorporating a speaker mounting case 27 to which a speaker 25 is attached is disposed inside a rear panel portion 10 configured behind the upper cover 9 placed above the outer frame 1 of the washing machine. The side opening 32 serving as a sound emitting hole is arranged so as to face the rear of the washing machine.

洗濯機外枠１の後方は、家屋の壁３６に近接するように設置されることが多いので、前記側面開口３２もまた、後方の壁３６に指向しかつ近接する。   Since the rear of the washing machine outer frame 1 is often installed so as to be close to the wall 36 of the house, the side opening 32 is also directed to and close to the rear wall 36.

断面略Ｌ字状のケース３０の、側面開口３２は略円筒形状に形成し、後部カバー１１の開口１２よりその端部３２ａを若干突出せしめ、後部カバー１１の内方の周囲にはフランジ３３を一体形成し、後部カバー１１の内面に気密的に密着させ、取り付けねじ３４にて後部カバー１１に固着する。   The side opening 32 of the case 30 having a substantially L-shaped cross section is formed in a substantially cylindrical shape, its end 32 a is slightly projected from the opening 12 of the rear cover 11, and a flange 33 is provided around the inner side of the rear cover 11. It is integrally formed, and is tightly adhered to the inner surface of the rear cover 11, and is fixed to the rear cover 11 with a mounting screw 34.

また、断面略Ｌ字状のケース３０の側面開口３２より内方には、格子状のフィルター部３５を一体形成し、図４で右方の開口より異物の侵入を防止する。   In addition, a lattice-like filter portion 35 is integrally formed inward of the side opening 32 of the case 30 having a substantially L-shaped cross section, and foreign matter is prevented from entering from the right opening in FIG.

以上のように構成された洗濯機について、以下その動作、作用を説明する。   About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

スピーカ２５の振動板（コーン紙）２６から発した音声は、図４にて示す矢印Ａの経路のように断面略Ｌ字状のケース３０の内部に沿って機外に伝達される。さらに家庭用洗濯機は、設置した部屋の壁３６に後面を近接して設置される事が一般的になされることが多いので、矢印Ａの経路方向に沿って伝達された音声は、後方の壁３６に反射され矢印Ｂの経路のように洗濯機前方に伝達する。従って、小型のスピーカであっても、使用者には可聴が十分な音圧となる。   The sound emitted from the diaphragm (cone paper) 26 of the speaker 25 is transmitted to the outside along the inside of the case 30 having a substantially L-shaped cross section as indicated by the path of arrow A shown in FIG. Furthermore, since the home washing machine is generally installed with the rear surface close to the wall 36 of the installed room, the sound transmitted along the path direction of the arrow A is The light is reflected by the wall 36 and transmitted to the front of the washing machine as indicated by the arrow B. Therefore, even for a small speaker, the sound pressure is sufficiently audible to the user.

また、スピーカ２５の設置は、断面略Ｌ字状のケース３０の側面開口３２より上方で、かつ振動板（コーン紙）２６は、側面開口３２とは９０度の傾斜を有して上方に配置しているので、側面開口３２より万一水の浸入等があっても、スピーカ２５への侵入の危険性はきわめて少ない構成である。   The speaker 25 is installed above the side opening 32 of the case 30 having a substantially L-shaped cross section, and the diaphragm (cone paper) 26 is disposed above the side opening 32 with an inclination of 90 degrees. Therefore, even if water enters from the side opening 32, the risk of entering the speaker 25 is extremely low.

また、スピーカ２５から発した音は、全てが断面略Ｌ字状のケース３０の内部を通過するものではなく、スピーカ取付ケース２７と断面略Ｌ字状のケース３０との微妙な隙間から洩れ、矢印Ｃの経路のように別の経路からも、後部カバー１１の開口１２部から外方に洩れようとする。   In addition, all the sound emitted from the speaker 25 does not pass through the inside of the case 30 having a substantially L-shaped cross section, but leaks from a delicate gap between the speaker mounting case 27 and the case 30 having a substantially L-shaped cross section. Even from another route, such as the route indicated by the arrow C, the outer cover 12 tries to leak outward from the opening 12 portion.

矢印ＡとＣの経路のように、伝達距離が異なる経路を通過してきた音は位相がずれており、洗濯機後方で音が合成した際、波長が干渉し音の音圧レベルを著しく低下させることがある。しかし、断面略Ｌ字状のケース３０のフランジ３３を、後部カバー１１の内面に気密的に密着させているので、矢印Ｃの経路を経てきた位相がずれた音は、後部カバー１１の開口１２とフランジ３３との隙間より外方に伝達する事はなく、音圧レベルの低下の恐れはない。   The sound passing through paths with different transmission distances, such as the paths of arrows A and C, is out of phase, and when the sound is synthesized behind the washing machine, the wavelength interferes and the sound pressure level of the sound is significantly reduced. Sometimes. However, since the flange 33 of the case 30 having a substantially L-shaped cross section is tightly adhered to the inner surface of the rear cover 11, the phase-shifted sound that has passed through the path indicated by the arrow C is not generated in the opening 12 of the rear cover 11. There is no possibility that the sound pressure level will be lowered because there is no transmission outside the gap between the flange 33 and the flange 33.

また、放音穴としての側面開口３２は、洗濯機の後方に位置しているので、家屋の壁３６に添って設置するという確率の高い洗濯機の設置状況から、子供等が指を差し込んだり小棒を差し込んだりする悪戯の危険性は極めて少ない構成である。   Moreover, since the side opening 32 as a sound emission hole is located behind the washing machine, a child or the like inserts a finger from the installation situation of the washing machine with a high probability of being installed along the wall 36 of the house. There is very little risk of mischief by inserting a small stick.

以上のように構成された本実施の形態においては、音声発生のスピーカを、洗濯機外枠の上部後方の後方パネル部の内部に配し、両端に上部開口と側面開口とを有する断面略Ｌ字状のケースの上部開口に、下方に向けて音声発生のスピーカの振動板（コーン紙）を配し、断面略Ｌ字状のケースの側面開口は、洗濯機の後方向に指向させて、洗濯機後方に放音をさせた事により、音声の放音穴からの水の浸入の危険性が減少し、スピーカの振動板（コーン紙）が直接外方に向かないため、外部からのスピーカの損傷の危険性を解消する事ができる。   In the present embodiment configured as described above, the sound generating speaker is disposed inside the rear panel portion on the upper rear side of the outer frame of the washing machine, and has an approximately L cross section having upper openings and side openings at both ends. A speaker diaphragm (cone paper) for sound generation is arranged downward in the upper opening of the letter-shaped case, and the side opening of the case having a substantially L-shaped cross section is directed backward in the washing machine, Since the sound is emitted to the rear of the washing machine, the risk of water intrusion from the sound emission hole is reduced, and the speaker diaphragm (cone paper) does not face directly outward. Can eliminate the risk of damage.

また、洗濯機の設置状況から洗濯機の後方の家屋壁面での音の反射により、小型のスピーカでも洗濯機前方での可聴音圧を高くする事ができる。   In addition, audible sound pressure in front of the washing machine can be increased even with a small speaker by reflecting sound on the wall of the house behind the washing machine from the installation state of the washing machine.

以上のように、本発明にかかる洗濯機は、スピーカを後方に配置することにより、外部からの水や異物の浸入を防止することが可能で、音声報知を行う家庭用の機器にも有用である。   As described above, the washing machine according to the present invention can prevent the intrusion of water and foreign matters from the outside by arranging the speaker at the rear, and is also useful for household devices that perform audio notification. is there.
