Description

本発明は、ブロワがブロワに定められた使用圧力範囲の上限を上回る圧力で使用された際に、そのことを使用者に知らせることができるブロワ用警報装置に関する。   The present invention relates to an alarm device for a blower that can notify a user when a blower is used at a pressure exceeding the upper limit of the working pressure range defined for the blower.

一般的なブロワは使用圧力範囲上限を上回る圧力で使用し続けると、コンプレッサが故障し動作不良となる可能性が高く、そうなった場合コンプレッサが修理不能となることがある。このような使用圧力範囲外での使用を防止するために、例えば特許文献１においては、ブロワの吐出配管からの吐出圧力をセンサにより検出し、検出した吐出圧力が設定した基準圧力の範囲外となった場合に、そのことを警報により使用者へ知らせることができるようになっている。   If a general blower continues to be used at a pressure exceeding the upper limit of the working pressure range, the compressor is likely to fail and malfunction, and the compressor may not be repairable. In order to prevent such use outside the operating pressure range, for example, in Patent Document 1, the discharge pressure from the discharge piping of the blower is detected by a sensor, and the detected discharge pressure is outside the set reference pressure range. When this happens, the user can be notified of this by an alarm.

しかし、このような警報装置は電源を必要とする警報機構を警報装置内に設ける必要があった。   However, such an alarm device has to be provided with an alarm mechanism that requires a power source in the alarm device.

本発明は、ブロワ用警報装置自体に電源を必要とせずに使用圧力上限を上回る圧力での使用を使用者に知らせることができるブロワ用警報装置を提供することを目的とする。   An object of the present invention is to provide a blower alarm device that can notify a user of use at a pressure exceeding the upper limit of the use pressure without requiring a power supply for the blower alarm device itself.

すなわち本発明は、ブロワからの吐出空気を通過させる主流路と、該主流路から分岐した分岐流路と、ブロワに定められた使用圧力範囲の上限を上回る圧力でブロワを使用した際に、該分岐流路からの吐出圧力により該分岐流路を開放する開放機構と、該分岐流路の開放時に該分岐流路から先へブロワの吐出空気が流れることで笛音を発する放音口により、警報音として笛音を発することのできる警報機構とを有することを特徴とするブロワ用警報装置を提供する。   That is, when the blower is used at a pressure exceeding the upper limit of the operating pressure range defined for the blower, the main flow passage through which the discharge air from the blower passes, the branch flow passage branched from the main flow passage, and the blower, An opening mechanism that opens the branch flow path by the discharge pressure from the branch flow path, and a sound emission port that emits a whistle sound when the blower discharge air flows forward from the branch flow path when the branch flow path is opened, There is provided an alarm device for a blower having an alarm mechanism capable of generating a whistle as an alarm sound.

本ブロワ用警報装置をブロワ吐出口と吐出対象物の間に取り付けることで、ブロワの使用圧力上限を上回る圧力での使用を使用者に知らせることができる。また、従来のブロワ用警報装置付きブロワのように、電源を必要とした警報機構を設ける必要が無い。   By attaching the alarm device for a blower between the blower discharge port and the discharge object, it is possible to notify the user of the use at a pressure exceeding the upper limit of the use pressure of the blower. Moreover, it is not necessary to provide an alarm mechanism that requires a power supply, unlike a conventional blower with an alarm device for a blower.

具体的には、前記開放機構が、該分岐流路を通して流れたブロワの吐出空気により一定以上の吐出圧力がかかることで、吐出方向へと変位して該分岐流路を開放する変位栓と、該変位栓を該分岐流路を閉止する位置へと付勢するスプリングとを有することができる。   Specifically, the opening mechanism is applied with a discharge pressure of a certain level or more by the discharge air of the blower flowing through the branch flow path, so that the displacement stopper is displaced in the discharge direction to open the branch flow path, And a spring for urging the displacement plug to a position for closing the branch passage.

前記開放機構は、圧力上限調整ネジと、該圧力調整ネジの先端に設けられ、該圧力上限調整ネジが締められたときに該スプリングを該変位栓との間で圧縮し、該変位栓の変位による該分岐流路の開放に必要な吐出圧力を大きくする調整板とを有することができる。   The release mechanism is provided at a pressure upper limit adjustment screw and a tip of the pressure adjustment screw, and when the pressure upper limit adjustment screw is tightened, the spring is compressed between the displacement stopper and the displacement stopper is displaced. And an adjusting plate for increasing the discharge pressure necessary for opening the branch flow path.

前記警報機構は、該変位栓が該分岐流路からの吐出方向へと一定距離変位することで該分岐流路から先へ流れた吐出空気の入口となる管口と、該管口へと流れた吐出空気を貯留し、貯留した吐出空気を該放音口へと流す送気空間とを有することができる。   The alarm mechanism is configured such that when the displacement stopper is displaced by a certain distance in the discharge direction from the branch flow path, a pipe port serving as an inlet for discharge air that has flowed forward from the branch flow path, and the flow to the pipe port It is possible to have an air supply space for storing the discharged air and flowing the stored discharged air to the sound outlet.

本発明の第１の実施形態に係るブロワ用警報装置１０は、図１及び図３に示すように、図示しないブロワからの吐出空気を通過させる主流路１２と、主流路１２から分岐した分岐流路１４と、分岐流路１４からの吐出圧力により分岐流路１４を開放する開放機構１６と、分岐流路１４から先へ吐出空気が流れることで警報音として笛音を発する警報機構１８とを備えている。開放機構１６は、分岐流路１４からの吐出圧力により吐出方向へと変位して分岐流路１４を開放する変位栓２０と、変位栓２０を分岐流路１４を閉止する閉止位置へ付勢するスプリング２２を有している。当該ブロワ用警報装置１０は、さらにブロワ吐出口と主流路１２とを接続する接続管２６を備えている。接続管２６はブロワ用警報装置１０から取り外し可能とされており、ブロワの吐出口の径に応じて種々の形式のものとすることができる。当該ブロワ用警報装置１０をブロワ吐出口と浄化槽や水槽等の吐出対象先との間に取り付けることで、後述するように、ブロワの使用圧力上限を上回る圧力での使用時に警報機構１８より警報音を発するようになっている。   As shown in FIGS. 1 and 3, the blower alarm device 10 according to the first embodiment of the present invention includes a main flow path 12 through which discharge air from a blower (not shown) passes, and a branched flow branched from the main flow path 12. A path 14, an opening mechanism 16 that opens the branch flow path 14 by the discharge pressure from the branch flow path 14, and an alarm mechanism 18 that emits a whistle sound as an alarm sound when discharge air flows from the branch flow path 14 to the front. I have. The opening mechanism 16 is displaced in the discharge direction by the discharge pressure from the branch flow path 14 to open the branch flow path 14 and urges the displacement plug 20 to the closed position where the branch flow path 14 is closed. A spring 22 is provided. The blower alarm device 10 further includes a connection pipe 26 that connects the blower outlet and the main flow path 12. The connecting pipe 26 is removable from the blower alarm device 10 and can be of various types according to the diameter of the blower outlet. By attaching the blower alarm device 10 between the blower discharge port and a discharge target such as a septic tank or a water tank, an alarm sound is output from the alarm mechanism 18 when used at a pressure exceeding the upper limit of the use pressure of the blower, as will be described later. Is coming out.

変位栓２０は、分岐流路１４からの吐出圧力により、変位栓２０が当接している分岐流路接面２８より吐出方向へと変位可能となっている。分岐流路１４からの吐出圧力が一定以上となると、変位栓２０が分岐流路接面２８からスプリング２２を圧縮しながら変位することで分岐流路１４は開放状態となり、分岐流路１４からの吐出空気は警報機構１８内へと流れる。   The displacement plug 20 can be displaced in the discharge direction from the branch flow channel contact surface 28 with which the displacement plug 20 abuts by the discharge pressure from the branch flow channel 14. When the discharge pressure from the branch flow path 14 exceeds a certain level, the displacement plug 20 is displaced while compressing the spring 22 from the branch flow path contact surface 28, thereby opening the branch flow path 14, and The discharged air flows into the alarm mechanism 18.

図３及び図４の通り、警報機構１８は、分岐流路１４から先へ流れた吐出空気の入口となる管口３４と、管口３４から流れた空気を貯留するための送気空間３８と、送気空間３８に貯留された空気を吐出して警報音としての笛音を発する放音口３６とを有している。管口３４から流れた空気を送気空間３８に貯留することで、放音口３６から安定して笛音を発することができるようになる。   As shown in FIGS. 3 and 4, the alarm mechanism 18 includes a pipe port 34 that serves as an inlet for the discharge air that has flowed from the branch flow path 14, and an air supply space 38 that stores the air that has flowed from the pipe port 34. The sound outlet 36 discharges air stored in the air supply space 38 and emits a whistle sound as an alarm sound. By storing the air flowing from the tube port 34 in the air supply space 38, it is possible to emit a whistle sound stably from the sound emission port 36.

ブロワ用警報装置１０の外部には、外部より警報機構１８内に水が浸入することを防止するため、放音口３６上部に吸水防止部材４０が設けられている。   Outside the blower alarm device 10, a water absorption preventing member 40 is provided above the sound outlet 36 in order to prevent water from entering the alarm mechanism 18 from the outside.

図２、図３及び図５の通り、スプリング２２の上部に設けられた圧力上限調整ネジ２４を締めることでスプリング２２を変位栓２０の方向へ圧縮する調整板３０と、圧力上限調整ネジ２４を調整する際に握り手部分となる調整部３２とを有している。調整部３２をつまんで圧力上限調整ネジ２４を締めることによりスプリング２２を変位栓２０の方向へ圧縮することで、変位栓２０の変位に必要な分岐流路１４からの吐出圧力を調整することができる。   As shown in FIGS. 2, 3, and 5, an adjustment plate 30 that compresses the spring 22 toward the displacement plug 20 by tightening the pressure upper limit adjustment screw 24 provided on the upper portion of the spring 22, and the pressure upper limit adjustment screw 24. It has the adjustment part 32 used as a grip part when adjusting. By compressing the spring 22 in the direction of the displacement plug 20 by pinching the adjustment unit 32 and tightening the pressure upper limit adjustment screw 24, the discharge pressure from the branch flow path 14 necessary for the displacement of the displacement plug 20 can be adjusted. it can.

図１及び図２に示すように、ブロワ用警報装置１０の警報装置上部４２と警報装置下部４４とは取り付けネジ４６により固定されている。   As shown in FIGS. 1 and 2, the alarm device upper portion 42 and the alarm device lower portion 44 of the blower alarm device 10 are fixed by mounting screws 46.

次に当該ブロワ用警報装置の動作について図３及び図５を参照にして説明する。まず、当該ブロワ用警報装置１０をブロワ吐出口と吐出対象先の間に取り付けた状態で、ブロワを使用圧力範囲内で使用している間は、図３に示すように変位栓２０が分岐流路接面２８と接して分岐流路１４を閉止している閉状態となる。このとき、分岐流路１４は閉じた状態であるため、接続管２６から、主流路１２、分岐流路１４へと流れたブロワの吐出空気は、分岐流路１４から管口３４へは流れない。   Next, the operation of the alarm device for the blower will be described with reference to FIGS. First, while the blower alarm device 10 is attached between the blower discharge port and the discharge target, while the blower is used within the operating pressure range, the displacement plug 20 is branched as shown in FIG. It will be in the closed state which has contacted the road contact surface 28 and closed the branch flow path 14. FIG. At this time, since the branch flow path 14 is in a closed state, the blower discharge air that has flowed from the connection pipe 26 to the main flow path 12 and the branch flow path 14 does not flow from the branch flow path 14 to the pipe port 34. .

使用圧力上限を上回る圧力でブロワを使用すると、図５に示すように分岐流路１４からの吐出圧力により、変位栓２０がスプリング２２を圧縮しながら変位して分岐流路１４を開放することで、接続管２６から主流路１２、分岐流路１４へと流れたブロワの吐出空気は、管口３４へと流れる。管口３４へ流れたブロワの吐出空気は、送気空間３８を通って放音口３６からブロワ用警報装置外部へと放出されることで警報音として笛音を発する。   When the blower is used at a pressure exceeding the upper limit of the working pressure, the displacement plug 20 is displaced while compressing the spring 22 by the discharge pressure from the branch flow path 14 as shown in FIG. The blower discharge air flowing from the connection pipe 26 to the main flow path 12 and the branch flow path 14 flows to the pipe port 34. The blower discharge air that has flowed to the pipe port 34 is emitted from the sound emission port 36 to the outside of the blower alarm device through the air supply space 38, thereby generating a whistle sound as an alarm sound.

このように当該ブロワ用警報装置１０においては、ブロワ吐出口と吐出対象先の間に取り付けることで、ブロワの使用圧力上限を上回る圧力で使用した際に警報音を発することができる。これにより、ブロワが使用圧力上限を上回る圧力で使用されていることを使用者に知らせることができる。また、従来のブロワ用警報装置付きブロワのように、ブロワの本体内に電源を必要とした警報機構を設ける必要が無い。   Thus, in the alarm device 10 for blowers, by attaching between the blower discharge port and the discharge target, an alarm sound can be emitted when used at a pressure exceeding the upper limit of the blower operating pressure. Thereby, it can inform a user that the blower is used at a pressure exceeding the upper limit of the working pressure. Further, unlike the conventional blower with an alarm device for a blower, there is no need to provide an alarm mechanism that requires a power source in the main body of the blower.

図６及び図７に示す本発明の第２の実施形態に係るブロワ用警報装置５０は、開放機構が上記第１の実施形態に係るブロワ用警報装置１０と異なる。当該実施形態における開放機構５１は、変位栓２０を円形状の受圧膜５２に変更している。受圧膜５２は、その外周が保持部材５４によって分岐流路１４に固定されており、ブロワの使用圧力範囲内での使用時には受圧膜５２により分岐流路１４が塞がれた閉状態となる。ブロワの使用圧力上限を上回る圧力が分岐流路１４から受圧膜５２にかかり続けることで受圧膜５２は破け、分岐流路１４は開放状態となる。分岐流路１４よりブロワの吐出空気が管口３４へと流れることで、第１の実施形態と同様に警報音として笛音を発することができる。   The blower alarm device 50 according to the second embodiment of the present invention shown in FIGS. 6 and 7 is different from the blower alarm device 10 according to the first embodiment in the opening mechanism. In the opening mechanism 51 in this embodiment, the displacement stopper 20 is changed to a circular pressure receiving film 52. The outer periphery of the pressure receiving film 52 is fixed to the branch flow path 14 by the holding member 54, and when the pressure receiving film 52 is used within the operating pressure range of the blower, the branch flow path 14 is closed by the pressure receiving film 52. The pressure exceeding the upper limit of the blower operating pressure continues to be applied to the pressure receiving film 52 from the branch flow path 14, thereby breaking the pressure receiving film 52 and opening the branch flow path 14. When the blower discharge air flows from the branch flow path 14 to the pipe port 34, a whistle sound can be emitted as an alarm sound as in the first embodiment.
