The code | symbol 12 is a bag body for massage devices which has the airtight chambers 11a-11d, and is connected with the said three-way valve | bulb V1-V4 via the supply paths 4a-4b for bag bodies.

図２は、前記三方向バルブＶ１の概略断面図である。なお、図１に示した他の三方向バルブＶ２〜Ｖ４も同様の構成とされ、その設置個数は、吸排気制御を別々に行う気密室の数に応じて決定される。   FIG. 2 is a schematic sectional view of the three-way valve V1. The other three-way valves V2 to V4 shown in FIG. 1 have the same configuration, and the number of installed valves is determined according to the number of airtight chambers that perform intake / exhaust control separately.

前記三方向バルブＶ１は、圧縮空気の供給と排気を切り換える分配弁２と、バルブの開閉動作を行うソレノイド部３とで構成される。前記分配弁２は、前記ヘッダー１と一体的に形成される弁箱２３と、弾性材で球形に形成された弁体２４と、前記弁箱２３の開口端部に設けられる板状の蓋部材２６と、前記弁箱２３のもう一方の開口端部に設けられるキャップ２８とで構成される。前記弁箱２３は、前記三方向バルブＶ１〜Ｖ４に対して供給口２１が連通するように形成されており、前記三方向バルブＶ１〜Ｖ４に対して一体的に形成された前記キャップ２８で前記供給口２１を閉鎖することで、連通した圧縮空気通路としての前記ヘッダー１が構成される。符号２９は、前記キャップ２８の内周面２７に当接して前記弁箱２３との気密を保つためのシール部材である。また、前記分配弁２には、前記マッサージ器用袋体１２に設けた気密室１１ａと前記袋体用供給路４ａを介して連通される分配口２２が形成される。さらに、供給口２１の縁部に前記弁体２４を当接する円錐面状もしくは球面状の弁座面２３ａが形成され、他方の前記蓋部材２６の縁部には、前記弁座面と同様の形状とされる排気口側弁座面２６ａが形成される。そして、前記弁体２４には、前記ソレノイド部３の作動軸３１の一端が取り付けられ、該作動軸３１の他端はソレノイド部３と連結され、該作動軸３１は前記蓋部材２６に形成した排気口２５を通って、左右動するように構成されている。   The three-way valve V1 includes a distribution valve 2 that switches between supply and exhaust of compressed air, and a solenoid unit 3 that opens and closes the valve. The distribution valve 2 includes a valve box 23 formed integrally with the header 1, a valve body 24 formed in a spherical shape with an elastic material, and a plate-like lid member provided at an opening end of the valve box 23. 26 and a cap 28 provided at the other opening end of the valve box 23. The valve box 23 is formed such that a supply port 21 communicates with the three-way valves V1 to V4, and the cap 28 is formed integrally with the three-way valves V1 to V4. By closing the supply port 21, the header 1 as a compressed air passage communicating therewith is configured. Reference numeral 29 is a seal member for contacting the inner peripheral surface 27 of the cap 28 to keep hermetic with the valve box 23. In addition, the distribution valve 2 is formed with a distribution port 22 communicating with the hermetic chamber 11a provided in the massager bag body 12 via the bag body supply path 4a. Further, a conical or spherical valve seat surface 23 a that contacts the valve body 24 is formed at the edge of the supply port 21, and the other cover member 26 has an edge similar to the valve seat surface. An exhaust port side valve seat surface 26a is formed. One end of the operating shaft 31 of the solenoid unit 3 is attached to the valve body 24, the other end of the operating shaft 31 is connected to the solenoid unit 3, and the operating shaft 31 is formed on the lid member 26. It is configured to move left and right through the exhaust port 25.

前記ソレノイド部３は、前記弁体２４に取り付けた前記作動軸３１と、該作動軸３１の端部と連結される可動部３２と、前記可動部３２およびコイル（不図示）を内蔵した電磁石ケース３３と、該電磁石ケース３３とフランジ部３４との間に設置されたスプリング３５とで構成される。   The solenoid unit 3 includes an electromagnet case including the operating shaft 31 attached to the valve body 24, a movable unit 32 connected to an end of the operating shaft 31, the movable unit 32, and a coil (not shown). 33, and a spring 35 installed between the electromagnet case 33 and the flange portion 34.

前記ソレノイド部３のコイルは、図に示す非通電状態（三方向バルブを閉じた状態）において、前記スプリング３５の反発力によって前記分配弁２側（図示左方向）に移動させられており、これに伴って、前記弁体２４は、前記弁座面２３ａに当接して前記供給口２１を閉鎖するとともに、前記分配口２２と前記排気口２５とを連通させている。すなわち、マッサージ器用袋体１２の内部の空気が排気される状態になっている。   The coil of the solenoid unit 3 is moved to the distributing valve 2 side (left direction in the figure) by the repulsive force of the spring 35 in a non-energized state (a state where the three-way valve is closed) shown in the figure. Accordingly, the valve body 24 abuts on the valve seat surface 23a to close the supply port 21, and allows the distribution port 22 and the exhaust port 25 to communicate with each other. That is, the air inside the massager bag 12 is exhausted.

一方、前記コイルに通電して電磁力を発生させる（三方向バルブを開いた状態）と、前記可動部３２がスプリング３５の弾発力に抗して前記電磁石ケース３３側（図示右方向）に引き込まれ、前記弁体２４は、前記弁座面２３ａから離れて前記排気口側弁座面２６ａに当接する。これに伴って、前記排気口２５を閉鎖するとともに、前記供給口２１と前記分配口２２とが連通される。すなわち、前記エアポンプ６からの圧縮空気を前記マッサージ器用袋体１２に送り込む状態となる。   On the other hand, when the coil is energized to generate electromagnetic force (when the three-way valve is opened), the movable portion 32 resists the elastic force of the spring 35 toward the electromagnet case 33 (right direction in the drawing). The valve body 24 is pulled in and is separated from the valve seat surface 23a and abuts on the exhaust port side valve seat surface 26a. Accordingly, the exhaust port 25 is closed, and the supply port 21 and the distribution port 22 are communicated with each other. That is, the compressed air from the air pump 6 is sent to the massager bag body 12.

なお、前記非通電状態おいて前記排気口２５から排出された空気は、前記マッサージ器本体５の内部に放出された後、該マッサージ器本体５に設けた通気口（不図示）から外部に放出される。   The air discharged from the exhaust port 25 in the non-energized state is discharged to the inside of the massage device body 5 and then discharged to the outside from a vent (not shown) provided in the massage device body 5. Is done.

図３は、本発明にかかるエアマッサージ器の一実施形態の概要外観図である。前記マッサージ用袋体１２は、上肢又は下肢に装着して手先から肩にかけてあるいは、足先から太ももにかけて膨張・収縮を繰り返すことによって押圧マッサージするものであり、本実施形態では両方の下肢に装着される。前記三方向バルブＶ１〜Ｖ４から前記袋体用供給路４ａ〜４ｄを介して送られる圧縮空気は、例えば本実施形態のように気密室１１ａ〜１１ｄがそれぞれ２個存在する際には、アダプタ１３を介して２分割され、両方の下肢に装着された各気密室１１ａ〜１１ｄに導入される。前記マッサージ器本体５の電源を投入した後、前記マッサージ器本体５に設けたスイッチ機構をオンにしてマッサージ（運転）を開始する。   FIG. 3 is a schematic external view of an embodiment of an air massager according to the present invention. The massage bag body 12 is attached to the upper limb or the lower limb and is pressed and massaged by repeatedly expanding and contracting from the hand tip to the shoulder or from the tip of the foot to the thigh. The The compressed air sent from the three-way valves V1 to V4 via the bag supply passages 4a to 4d has an adapter 13 when there are two airtight chambers 11a to 11d, respectively, as in the present embodiment. And is introduced into each of the airtight chambers 11a to 11d attached to both lower limbs. After the massage device body 5 is turned on, a switch mechanism provided on the massage device body 5 is turned on to start massage (operation).

運転を開始すると、前記エアポンプ６（図１参照）が作動して、圧縮空気が前記タンク７に供給される。前記制御部８は、予め記憶しておいたパターン（設定モード）に従って前記各ソレノイド部３の通電のオン・オフ、すなわち前記三方向バルブＶ１〜Ｖ４の開閉制御を行う。前記設定モードは、例えば、つま先側の気密室１１ａから太もも側の１１ｄに向かって順次給気と排気を繰り返すウェーブモード（Ａモード）、つま先側の気密室１１ａから太もも側の気密室１１ｄに向かって順次給気を行って、設定圧力を一定時間保持した後に気密室１１ａ〜１１ｄを同時に排気するスクイーズモード（Ｂモード）、さらに、気密室１１ａ〜１１ｄに対してわずかな時間差でほぼ同時に給気を行い、設定圧力を一定時間保持した後に同時に排気を行うハイパーモード（Ｃモード）が用意されるが、上記に限定されるものではなく、様々な設定モードを記憶させておくことができる。   When the operation is started, the air pump 6 (see FIG. 1) is operated, and compressed air is supplied to the tank 7. The control unit 8 performs on / off of energization of each solenoid unit 3, that is, opening / closing control of the three-way valves V1 to V4, according to a pattern (setting mode) stored in advance. The setting mode is, for example, a wave mode (A mode) in which air supply and exhaust are sequentially repeated from the toe side airtight chamber 11a toward the thigh side 11d, and from the toe side airtight chamber 11a to the thigh side airtight chamber 11d. The squeeze mode (B mode) for exhausting the airtight chambers 11a to 11d simultaneously after holding the set pressure for a certain period of time, and supplying the air almost simultaneously with a slight time difference from the airtight chambers 11a to 11d. However, the present invention is not limited to the above, and various setting modes can be stored.

図４は、本発明にかかるエアマッサージ器異常検出システムにおける圧力異常の検知とその対応の手順を示したフローチャートであり、所定の周期で繰り返し実行される。   FIG. 4 is a flowchart showing the detection of pressure abnormality in the air massager abnormality detection system according to the present invention and the procedure for dealing with it, and is repeatedly executed at a predetermined cycle.

ステップＳ１１では、電源がオンになった（電源投入）か否かが判定され、電源がオンになったと判定されればステップＳ１２へ進む。該ステップＳ１２では、前記圧力センサ９にて計測される圧力（以下、圧力）が所定圧力Ｐ１（例えば17.7kPa）以上であるか否かが判定される。圧力が所定圧力Ｐ１以上であると判定されると、ステップＳ５０の異常モード動作に進む。該異常モード動作では、１．エアポンプ６の停止、２．バルブＶ１〜Ｖ４の閉動作（排気状態にする）、３．警報ブザーオン、４．電源ランプ点滅、の各動作が実行される。前記ステップＳ１２は、ステップＳ１３で運転開始となるまでの待機中の動作であり、前記圧力センサ９のショート（故障により圧力無限大を計測）または前記エアポンプ６の停止不能のいずれかの異常が発生したかどうかを検知するものである。なお、「Pa」は圧力の単位の「パスカル」を意味する（１気圧≒100kPa）。   In step S11, it is determined whether or not the power is turned on (power is turned on). If it is determined that the power is turned on, the process proceeds to step S12. In step S12, it is determined whether or not the pressure (hereinafter referred to as pressure) measured by the pressure sensor 9 is equal to or higher than a predetermined pressure P1 (for example, 17.7 kPa). If it is determined that the pressure is equal to or higher than the predetermined pressure P1, the process proceeds to an abnormal mode operation in step S50. In the abnormal mode operation, 1. Stop air pump 6. 2. The valve V1 to V4 are closed (exhaust state); 3. Alarm buzzer on Each operation of the power lamp blinking is executed. The step S12 is a standby operation until the operation is started in the step S13, and either the short-circuit of the pressure sensor 9 (measurement of infinite pressure due to a failure) or the inability to stop the air pump 6 occurs. It is to detect whether or not. “Pa” means “pascal” which is a unit of pressure (1 atm≈100 kPa).

また、前記ステップＳ１２で、圧力が所定圧力Ｐ１以上でないと判定されれば、運転開始ステップであるステップＳ１３に進んで前記運転が開始されたか否かを判定し、前記運転が開始されたと判定されるとステップＳ１４へ進む。該ステップＳ１４では、前記三方向バルブＶ１を開き、所定時間ｔ１（例えば0.5秒）が経過した後に前記三方向バルブＶ１を閉じる。該ステップＳ１４の動作は、前記タンク７内の残留圧力を除去するために行われる。なお、各所定時間は、前記制御部８内のタイマ１０にて計測されている。続くステップＳ１５では、圧力が所定圧力Ｐ２（例えば0.4kPa）以下であるか否かが判定される。前記ステップＳ１５にて所定圧力以下でないと判定されると前記ステップＳ５０の異常モード動作に進み、所定圧力以下であると判定されるとステップＳ１６に進んで、エアポンプ６を所定の出力（例えば40％）で駆動する（所定出力エアポンプ駆動ステップ）。前記ステップＳ１５は、前記ステップＳ１４が正常に行われたか否かを判定するものであり、前記三方向バルブＶ１の異常、前記圧力センサ９のショートまたは前記エアポンプ６の停止不能のいずれかの異常が発生したかどうかを検知するものである。   If it is determined in step S12 that the pressure is not equal to or higher than the predetermined pressure P1, the process proceeds to step S13, which is an operation start step, to determine whether or not the operation is started, and it is determined that the operation is started. Then, it progresses to step S14. In step S14, the three-way valve V1 is opened, and the three-way valve V1 is closed after a predetermined time t1 (for example, 0.5 seconds) has elapsed. The operation of step S14 is performed to remove the residual pressure in the tank 7. Each predetermined time is measured by the timer 10 in the control unit 8. In subsequent step S15, it is determined whether or not the pressure is equal to or lower than a predetermined pressure P2 (for example, 0.4 kPa). If it is determined in step S15 that the pressure is not lower than the predetermined pressure, the process proceeds to the abnormal mode operation in step S50. If it is determined that the pressure is lower than the predetermined pressure, the process proceeds to step S16, and the air pump 6 outputs a predetermined output (for example, 40%). ) (Predetermined output air pump driving step). The step S15 is for determining whether or not the step S14 has been normally performed, and there is an abnormality in any one of the abnormality of the three-way valve V1, the short-circuit of the pressure sensor 9, or the inability to stop the air pump 6. This is to detect whether it has occurred.

続くステップＳ１７では、前記ステップＳ１６の後、所定時間ｔ２（例えば1.5秒）以内に所定圧力Ｐ３（例えば4kPa以上）以上に達したか否かが判定され、達していないと判定されると前記ステップＳ５０の異常モード動作へ進む。前記ステップＳ１７で、所定時間ｔ２以内に所定圧力Ｐ３以上に達したと判定されると、予圧モードステップであるステップＳ１８に進んで予圧モードを開始する。前記ステップＳ１７は、前記ステップＳ１６の開始後に正常な速度で圧力が上昇するか否かを判断するものであり、これに伴い、前記圧力センサ９のオープン（故障により圧力ゼロを計測）、前記エアポンプ６の運転不能、前記三方向バルブＶ１〜Ｖ４の閉動作不能、前記圧力センサ用供給路１６の全折れ（完全に詰まる）または抜けおよび破断（圧力がかからない）、前記圧力センサ供給路１６の半折れ（やや詰まる）のいずれかの異常が発生したかどうかを検知するものである。   In the subsequent step S17, after the step S16, it is determined whether or not a predetermined pressure P3 (for example, 4 kPa or more) has been reached within a predetermined time t2 (for example, 1.5 seconds). Proceed to the abnormal mode operation of S50. If it is determined in step S17 that the pressure has reached the predetermined pressure P3 or more within the predetermined time t2, the process proceeds to step S18, which is a preload mode step, and the preload mode is started. In step S17, it is determined whether or not the pressure increases at a normal speed after the start of step S16. Accordingly, the pressure sensor 9 is opened (pressure zero is measured due to a failure), the air pump 6, the three-way valves V1 to V4 cannot be closed, the pressure sensor supply passage 16 is completely broken (completely clogged) or disconnected (no pressure is applied), and the pressure sensor supply passage 16 is half This is to detect whether any abnormality of breakage (slightly clogging) has occurred.

前記ステップＳ１８では、前記気密室１１ａ〜１１ｄに対してわずかな時間差でほぼ同時に給気を行う予圧モードを開始し、設定圧力に達した後に排気を行うとともに設定圧力に達するまで設定モードランプ（不図示）を点滅させる。続くステップＳ１９では、任意に選択した前記設定モードに移行して、前記設定モードランプを点灯させる。   In step S18, a preload mode is started in which air is supplied almost simultaneously with a slight time difference with respect to the airtight chambers 11a to 11d. After reaching the set pressure, exhausting is performed and the set mode lamp (invalid until the set pressure is reached). Blink (shown). In the subsequent step S19, the mode is changed to the arbitrarily selected setting mode, and the setting mode lamp is turned on.

以上で、マッサージ器の揉み始めの前の動作が終わり、以降では揉み動作に入る。なお、前記Ｂモードでは、前記三方向バルブＶ１〜Ｖ４の開閉タイミングは、図６のように行われる。該図にて三方向バルブＶ１の動作に注目する。時間ｔ０にて三方向バルブＶ１のソレノイド部３に通電されると該三方向バルブＶ１に連結された気密室の圧力が高まり始め、ｔ１０にて設定圧力に達する。そして、該設定圧力を所定時間保持した後、ｔ２０にて通電を停止すると、前記三方向バルブＶ１が排気状態になるとともに、前記気密室の圧力がゼロに戻る。他の三方向バルブＶ２〜Ｖ４の開閉動作は、図示のタイミングで行われる。   With the above, the operation before the start of massaging of the massage device is completed, and thereafter the massaging operation is started. In the B mode, the opening and closing timings of the three-way valves V1 to V4 are performed as shown in FIG. In the figure, attention is paid to the operation of the three-way valve V1. When the solenoid part 3 of the three-way valve V1 is energized at time t0, the pressure in the hermetic chamber connected to the three-way valve V1 starts to increase, and reaches the set pressure at t10. Then, after holding the set pressure for a predetermined time, when the energization is stopped at t20, the three-way valve V1 enters an exhausted state and the pressure in the hermetic chamber returns to zero. The opening and closing operations of the other three-way valves V2 to V4 are performed at the timing shown in the drawing.

さて、ステップＳ２０では、前記三方向バルブＶ１を開いて所定時間ｔ４（例えば0.3秒）が経過した後に所定圧力Ｐ４（例えば1kPa）以下であるか否かが判定される。所定時間ｔ４経過後に所定圧力Ｐ４以下でないと判定されると前記ステップＳ５０の異常モード動作へ進み、所定時間ｔ４経過後に所定圧力Ｐ４以下になったと判定されると、ステップＳ２１へ進む。前記ステップＳ２０は、前記三方向バルブＶ１の開動作の直後にある程度の圧力が抜けたか否かを判断するものであり、これに伴って、前記三方向バルブＶ１の開動作不能、前記三方向バルブＶ１の閉動作不能のいずれかの異常が発生したかどうかを検知するものである。   In step S20, it is determined whether or not the pressure is equal to or lower than a predetermined pressure P4 (for example, 1 kPa) after the three-way valve V1 is opened and a predetermined time t4 (for example, 0.3 seconds) has elapsed. If it is determined that the pressure is not lower than the predetermined pressure P4 after the lapse of the predetermined time t4, the process proceeds to the abnormal mode operation of the step S50, and if it is determined that the pressure is lower than the predetermined pressure P4 after the lapse of the predetermined time t4, the process proceeds to the step S21. The step S20 determines whether or not a certain pressure has been released immediately after the opening operation of the three-way valve V1, and accordingly, the opening operation of the three-way valve V1 is impossible. This is to detect whether any abnormality of V1 incapable of closing operation has occurred.

前記ステップＳ２１では、前記三方向バルブＶ１を開いて所定時間ｔ５（例えば４秒）が経過した後に所定圧力Ｐ５（例えば0.4kPa）以上であるか否かが判定される。所定時間ｔ５経過後に所定圧力Ｐ５以上でないと判定されると前記ステップＳ５０の異常モード動作へ進み、所定時間ｔ５経過後に所定圧力Ｐ５以上になったと判定されると、ステップＳ２２へ進む。前記ステップＳ２１は、前記三方向バルブＶ１の開動作から十分に時間が経過した後に前記圧力センサ９が正常に作動しているか否かを判断するものであり、これに伴って、前記圧力センサ９のオープン、前記圧力センサ用供給路１６の全折れまたは抜けおよび破断、前記圧力センサ供給路１６の半折れ、前記エアポンプ６の運転不能のいずれかの異常が発生したかどうかを検知するものである。なお、ステップＳ２２（破線のＡ部）の動作は、後で図５を参照して詳しく説明する。   In step S21, it is determined whether or not the pressure is equal to or higher than a predetermined pressure P5 (for example, 0.4 kPa) after the three-way valve V1 is opened and a predetermined time t5 (for example, 4 seconds) has elapsed. When it is determined that the pressure is not equal to or higher than the predetermined pressure P5 after the lapse of the predetermined time t5, the process proceeds to the abnormal mode operation of the step S50, and when it is determined that the pressure exceeds the predetermined pressure P5 after the lapse of the predetermined time t5, the process proceeds to a step S22. The step S21 determines whether or not the pressure sensor 9 is operating normally after a sufficient time has elapsed since the opening operation of the three-way valve V1, and accordingly, the pressure sensor 9 Is detected, whether the pressure sensor supply path 16 is completely broken or disconnected and broken, the pressure sensor supply path 16 is half-folded, or the air pump 6 cannot be operated. . Note that the operation in step S22 (part A of the broken line) will be described in detail later with reference to FIG.

また、異常モード用検知のステップには、ステップＳ２３とステップＳ２４も設けられている。前記ステップＳ２３では、排気中に圧力が所定圧力Ｐ１（例えば17.7kPa）以上になると前記ステップＳ５０の異常モード動作に移行する。該ステップＳ２３は、排気中であるにもかかわらず圧力が下がらない状態を検知するものであり、これに伴って、前記圧力センサ９のショート、前記エアポンプ６の停止不能のいずれかの異常が発生したかどうかを検知するものである。また、前記ステップＳ２４では、運転中（排気中を除く）に圧力が設定圧力より所定圧力Ｐ６（例えば2kPa）以上高くなってそのまま所定時間ｔ６（例えば１秒）が経過すると、前記ステップＳ５０の異常モード動作に移行する。該ステップＳ２４は、圧力が許容範囲以上に高まった状態が続かないか否かを運転中に常時監視するものであり、これに伴って、前記圧力センサ９のショート、前記エアポンプ６の停止不能のいずれかの異常が発生したかどうかを検知するものである。   Further, step S23 and step S24 are also provided in the abnormal mode detection step. In step S23, when the pressure becomes higher than a predetermined pressure P1 (for example, 17.7 kPa) during exhaust, the process proceeds to the abnormal mode operation in step S50. This step S23 detects a state in which the pressure does not drop despite exhausting, and accompanying this, either a short circuit of the pressure sensor 9 or an inability to stop the air pump 6 occurs. It is to detect whether or not. In step S24, if the pressure becomes higher than the set pressure by a predetermined pressure P6 (for example, 2 kPa) during operation (except during exhaust) and a predetermined time t6 (for example, 1 second) elapses, the abnormality in step S50 is performed. Transition to mode operation. The step S24 constantly monitors during operation whether or not the state where the pressure has increased beyond the allowable range continues, and accordingly, the pressure sensor 9 is short-circuited and the air pump 6 cannot be stopped. It detects whether any abnormality has occurred.
