技術分野  Technical field
[0001] 本発明は、建物の壁面等に設けた換気口を外気温度あるいは室内温度等に応じ て開閉させるために用いられる住宅設備用の換気装置に関し、特に温度変化に伴い 作動するサーモアクチユエータ、たとえばサーモエレメントのピストンの進退動作に伴 つて換気口に設けた蓋体を開閉駆動するために用いて好適なサーモアクチユエータ 付き換気装置に関する。  TECHNICAL FIELD [0001] The present invention relates to a ventilator for residential equipment used to open and close a ventilation opening provided on a wall surface of a building in accordance with an outside air temperature or a room temperature, and in particular, a thermoactuator that operates in accordance with a temperature change. The present invention relates to a ventilator with a thermoactuator suitable for use in opening and closing a lid provided at an air vent in accordance with the forward / backward movement of a piston of a thermo element, for example.
背景技術  Background art
[0002] 温度変化、たとえば外気温度により換気口に設けた蓋体を開閉駆動するために、 温度変化を感知して作動するサーモアクチユエータとしてサーモエレメントを用いた 換気装置が知られている。このような換気装置では、サーモエレメントの感温部に設 けたサーモワックス等の熱膨張体の膨張、収縮により進退動作するピストンの動きで 、前記蓋体を自動的に開閉動作させる構成となっている (例えば、特許文献 1、 2参 照)。  A ventilator using a thermo element is known as a thermoactuator that operates by sensing a change in temperature in order to open and close a lid provided at a ventilation port according to a temperature change, for example, an outside air temperature. In such a ventilator, the lid body is automatically opened and closed by the movement of a piston that moves forward and backward by expansion and contraction of a thermal expansion body such as thermowax provided in the temperature sensing part of the thermoelement. (For example, see Patent Documents 1 and 2).
[0003] 従来この種のサーモアクチユエータ付きの換気装置では、たとえば外気温度が所 定値以下となったときに蓋体をスプリングの付勢力で閉じ、所定値以上となったときに サーモエレメントの感温部が作動してピストンの前進により開くように動作させることに より、換気を制御するように構成されている。特に、上述したサーモエレメントのピスト ンは、温度変化に応じて前進量が増減するものであり、それに応じた蓋体の開度制 御を行えることから、換気装置として効果的な換気を行えるのである。  [0003] Conventionally, in this type of ventilator with a thermoactuator, for example, when the outside air temperature falls below a predetermined value, the lid is closed by the urging force of a spring, and when the temperature rises above a predetermined value, It is configured to control ventilation by operating the temperature sensor and opening it by the advance of the piston. In particular, the thermo element piston described above increases or decreases the advance amount in response to temperature changes, and the lid opening can be controlled accordingly. is there.
[0004] ところで、上述した従来のサーモアクチユエータ付きの換気装置では、一般に、寒 い時には閉状態、暑い時には開状態となるように蓋体の開閉動作が設定されている 。そして、この設定とは逆に、寒い時に開状態、暑い時に閉状態となるような設定変 更を行って使用するには、適宜の部品を新規部品に交換する等の対策を講じること が必要であった。 [0004] By the way, in the above-described conventional ventilator with a thermoactuator, the lid opening / closing operation is generally set so as to be closed when it is cold and open when it is hot. In contrast to this setting, to change the setting so that it is open when it is cold and closed when it is hot, it is necessary to take measures such as replacing appropriate parts with new parts. Met.
[0005] このような蓋体の開閉方向を切り替えることが可能な機構として、たとえばサーモェ レメントをサ一モアクチユエータとした冷暖房用の風向切換装置が知られている(例え ば、特許文献 3参照)。 As a mechanism capable of switching the opening / closing direction of such a lid, for example, a thermo A wind direction switching device for air conditioning that uses a mentament as a thermoactuator is known (see, for example, Patent Document 3).
この従来装置では、風向切換羽根とサーモエレメントとを一体ィ匕し、容易に取り外し 、取付可能に構成しており、周囲温度、季節等の環境条件に応じて最適な風向切換 羽根の角度を設定できる構造となっている。  In this conventional device, the wind direction switching blade and the thermo element are integrated and can be easily removed and installed. The optimum angle of the wind direction switching blade is set according to the environmental conditions such as ambient temperature and season. It has a structure that can be done.

発明が解決しょうとする課題  Problems to be solved by the invention
[0007] しかし、上述した特許文献 3のサーモエレメント付きの風向切換装置で採用されて いる開閉方向の切換装置では、構造が複雑で、構成部品点数も多くなり、組付け性 も悪ぐしかも空気通路を閉状態とすることができない構造上での問題もあり、また換 気装置としての構造上から単純には採用することができないものであった。  [0007] However, the switching device for the opening and closing direction employed in the air direction switching device with the thermo element of Patent Document 3 described above has a complicated structure, a large number of components, poor assembly, and air. There were also problems in the structure in which the passage could not be closed, and it was not possible to simply adopt the structure as a ventilation device.
[0008] したがって、従来力 この種の換気装置にお 、て、使用環境に応じて対処するため に、換気口に設けた蓋体の開閉方向を必要に応じて切り替えて二つの異なる仕様、 すなわち蓋体を開状態カも閉状態に、あるいは閉状態力も開状態へと、動作方向を 逆向きに変化させることができるような対策を講じることが望まれている。特に、換気 装置において必要とされることは、新規部品の追加、変更等を必要とせずに、蓋体の 開閉方向を切り替えることができるように構成することである。  [0008] Therefore, in order to cope with the conventional force according to the usage environment in this type of ventilator, the opening and closing direction of the lid provided at the ventilation opening is switched as necessary, that is, two different specifications, It is desired to take measures to change the direction of operation in the opposite direction, such as when the lid is opened or closed, or when the closing force is opened. In particular, what is needed in the ventilator is to be able to switch the opening and closing direction of the lid without the need to add or change new parts.
また、このような切り替えも、簡単な組み替え作業で行えることも望まれている。  It is also desired that such switching can be performed with a simple rearrangement operation.
[0009] また、上述したサーモエレメント付きの換気装置では、サーモエレメントが、ピストン を所定量以上に押出したときに、蓋体を必要以上に動作させないようなオーバリフト 防止機構を付加する必要がある。このようなオーバーリフト防止機能がないと、回転を 規制されること等によりピストンの動きが規制され、これによりサーモエレメント内部に 過大な圧力が発生し、サーモエレメントを構成するピストンの折損やダイヤフラムの損 傷を引き起こし、 、わゆるサーモエレメントの破損を招 、てしまうおそれがある力 で ある。また、このようなオーバーリフト防止機能は、蓋体を構成する各部品などの損傷 を防ぐうえでも必要となって 、る。 [0009] Further, in the above-described ventilation device with a thermo element, it is necessary to add an overlift prevention mechanism that prevents the lid from operating more than necessary when the thermo element pushes the piston beyond a predetermined amount. . Without such an overlift prevention function, the movement of the piston is restricted by restricting the rotation, etc., which causes an excessive pressure to be generated inside the thermo element, causing breakage of the piston constituting the thermo element and the diaphragm. This is a force that can cause damage and cause damage to the thermo element. In addition, such an overlift prevention function can damage each part of the lid. It is necessary to prevent it.
[0010] 本発明はこのような事情に鑑みてなされたものであり、蓋体の開閉方向の切り替え を、余分な新規部品を用いずに、しかも簡単な切り替え作業により簡単に設定するこ とが可能で、し力も蓋体の回動量を任意の特性をもって調整する機能は勿論、ォー ノ《リフト防止機能を備えるとともに、火災に対しての防火機能等も備え、コスト的にも 安価な簡易型構造をもつサーモアクチユエータ付き換気装置を得ることを目的とする 課題を解決するための手段  [0010] The present invention has been made in view of such circumstances, and the switching of the opening and closing direction of the lid can be easily set by a simple switching operation without using an extra new part. It is possible to adjust the amount of rotation of the lid with arbitrary characteristics, as well as the on-lift function and anti-lift function.

[0011] このような目的に応えるために本発明(請求項 1記載の発明)に係るサーモアクチュ エータ付き換気装置は、換気口を開閉するように回動自在に軸支される蓋体と、温 度変化に伴 、作動するサーモアクチユエータと、このサーモアクチユエータが作動す ることにより前記蓋体を開閉動作させるためのリンク機構を構成するリテーナ部材と、 前記蓋体を回動自在に軸支するとともに前記リテーナ部材を進退動作可能に保持 するホルダ部材とを備え、前記蓋体に設けた係合端を前記リテーナ部材の被係合部 に係合させることにより、蓋体を開閉駆動するように構成されてなり、前記リテーナ部 材の被係合部に対して蓋体の係合端を係合させる方向を変更することにより、蓋体を 常時は閉状態としこの閉状態力 開状態へと変化させる第 1の換気動作と、常時は 開状態としこの開状態力 閉状態へと変化させる第 2の換気動作とのいずれ力が選 択されるように構成したことを特徴とする。  In order to meet such an object, a ventilator with a thermoactuator according to the present invention (the invention according to claim 1) includes a lid body that is pivotally supported so as to open and close a ventilation port, A thermoactuator that operates as the temperature changes, a retainer member that forms a link mechanism for opening and closing the lid when the thermoactuator operates, and the lid is rotatable And a holder member that holds the retainer member so that the retainer member can be moved forward and backward.

[0014] A ventilator with a thermoactuator according to the present invention (invention according to claim 4) is the ventilator with a thermoactuator according to claim 1, claim 2, or claim 3, wherein the retainer member is The engaged portion of the lid body rotates in response to changes in ambient temperature by the relative movement of the engagement end of the lid body due to the movement of the retainer member accompanying the operation of the thermoactuator. It is formed so that the operation amount can be varied.
[0015] 本発明(請求項 5記載の発明)に係るサーモアクチユエータ付き換気装置は、請求 項 1ないし請求項 4のいずれ力 1項に記載のサーモアクチユエータ付き換気装置に おいて、周囲温度が所定の温度以上になったときに、前記蓋体の係合端と前記リテ 一ナ部材の被係合部との係合状態の如何にかかわらず、該蓋体の動きを係止する口 ック部を設けたことを特徴とする。  [0015] A ventilator with a thermoactuator according to the present invention (invention according to claim 5) is the ventilator with a thermoactuator according to any one of claims 1 to 4, When the ambient temperature exceeds a predetermined temperature, the movement of the lid is locked regardless of the engagement state between the engagement end of the lid and the engaged portion of the retainer member. It is characterized by the provision of a mouth part to be used.
[0016] 本発明(請求項 6記載の発明)に係るサーモアクチユエータ付き換気装置は、請求 項 1ないし請求項 5のいずれ力 1項に記載のサーモアクチユエータ付き換気装置に おいて、前記リテーナ部材は、前記サーモアクチユエータの作動により前記蓋体の係 合端が当接係合することにより該蓋体を開閉動作させるための被係合部としてのカム 面を有し、このリテーナ部材のカム面に対して蓋体の係合端を当接させる方向を変 更することにより、第 1の換気動作と第 2の換気動作とのいずれかが選択されるように 構成されて ヽることを特徴とする。  [0016] A ventilator with a thermoactuator according to the present invention (invention according to claim 6) is the ventilator with a thermoactuator according to any one of claims 1 to 5, The retainer member has a cam surface as an engaged portion for opening and closing the lid when the engagement end of the lid is brought into contact with and engaged by the operation of the thermoactuator. By changing the direction in which the engagement end of the lid abuts against the cam surface of the retainer member, either the first ventilation operation or the second ventilation operation is selected. It is characterized by scolding.
[0017] 本発明によれば、たとえばサーモアクチユエータをサーモエレメントで構成した場合 にお 、て、屋外の外気温度中あるいは室内温度中に臨んで 、るサーモエレメントの 熱膨張体が、外気温度等の温度上昇によって膨張し、ピストンを突出する方向に押 し出すと、リテーナ部材は反ホルダ部材側に移動する。すると、リテーナ部材の被係 合部(たとえばカム面)に係合している蓋体側の係合端 (たとえば可動軸)は、該被係 合部の動きに伴って移動し、結果として蓋体が、前記外気温度等の温度上昇に従つ て閉動作することになる。  [0017] According to the present invention, for example, when the thermoactuator is configured by a thermoelement, the thermal expansion body of the thermoelement facing the outdoor outdoor temperature or the indoor temperature is the outdoor air temperature. When the piston expands due to a temperature rise or the like and pushes out the piston in the protruding direction, the retainer member moves to the side opposite to the holder member. Then, the engagement end (for example, the movable shaft) on the lid side engaged with the engaged portion (for example, the cam surface) of the retainer member moves in accordance with the movement of the engaged portion, and as a result, the lid body. However, the closing operation is performed as the temperature rises such as the outside air temperature.
[0018] さらに、外気温度等が温度上昇して熱膨張体が膨張し、ピストンが蓋体を閉状態以 上に押し出したときには、蓋体の動きは、該蓋体あるいはリテーナ部材がロック部に 係止されることによりロックされて閉状態を維持する一方、前記ピストンの押出し力は 、蓋体の係合端がリテーナ部材の被係合部から離脱して非係合状態となったり、ある いは蓋体の係合端が係合して 、る被係合部を有するリテーナ部材が弾性支持力に 抗して動くことで吸収されるようになって!/、る。 [0018] Further, when the temperature of the outside air rises and the thermal expansion body expands and the piston pushes the lid body beyond the closed state, the movement of the lid body causes the lid body or the retainer member to move to the lock portion. While being locked and locked to maintain the closed state, the pushing force of the piston may cause the engagement end of the lid body to be disengaged from the engaged portion of the retainer member, or may be in a disengaged state. Alternatively, the engaging end of the lid is engaged, and the retainer member having the engaged portion moves against the elastic supporting force to be absorbed! /.
[0019] 以上の構成によるサーモアクチユエータ付き換気装置によれば、外気温度あるいは 室内温度が低く寒い時に換気口を開き、暑い時に閉じるようにすることができる。さら に、これとは逆に、外気温度あるいは室内温度が低くて寒い時に換気口を閉じ、暑い 時に開くように構成することが求められることもある。このような場合には、前記サーモ ァクチユエータの作動方向及び設置位置は変更せず、つまりサーモアクチユエータ はそのままに、蓋体をホルダ部材から取り外し、蓋体のホルダ部材への取付け向きを 逆にし、またコイルばねによる付勢方向等を変更することで対処できる。  [0019] According to the ventilator with a thermoactuator having the above-described configuration, the ventilation opening can be opened when the outside air temperature or the room temperature is low and the temperature is cold, and can be closed when the temperature is hot. Furthermore, conversely, it may be required to configure the vent to close when the outside air temperature or room temperature is low and it is cold, and open when it is hot. In such a case, the operating direction and the installation position of the thermoactuator are not changed, that is, the lid is removed from the holder member while the thermoactuator is left as it is, and the mounting direction of the lid on the holder member is reversed. Further, it can be coped with by changing the urging direction by the coil spring.
[0020] このようにすると、蓋体は、常時は換気口を閉じる状態にあり、温度上昇に伴ってサ ーモエレメントの働きで徐々に換気口を開くように動作されるのである。このときも、所 定温度以上のピストンの動きは、リテーナ部材には伝わる力 蓋体の開動作は、該リ テーナ部材が固定部側に設けたロック部に係止されることでロックされるようになって いる。 [0020] In this way, the lid is normally in a state of closing the ventilation opening, and is operated to gradually open the ventilation opening by the action of the thermo element as the temperature rises. At this time, the movement of the piston above the predetermined temperature is transmitted to the retainer member. The opening operation of the lid is locked by the retainer member being locked by the lock portion provided on the fixed portion side. It is like this.
そして、このような構成によれば、換気装置の構成部品はそのままに、蓋体の組付 け方向を変えるだけで、蓋体の開閉動作を逆に構成することができるのであり、新規 部品は不要で、コスト低減が図れるば力りでなぐ組立ても容易であり、し力も蓋体の 回転軸等の位置は同じであるから、装置の大型化を招くおそれはなぐまた形状も簡 単である等の利点がある。  According to such a configuration, the opening / closing operation of the lid can be reversed by simply changing the assembly direction of the lid without changing the components of the ventilator. It is unnecessary and can be assembled easily with force if the cost can be reduced, and the position of the rotating shaft of the lid is the same as the force, so there is no risk of increasing the size of the device and the shape is simple. There are advantages such as.
[0021] ここで、上述したように換気装置を、常時は閉状態とし、閉状態から開状態へと変化 させたり、常時は開状態とし、開状態力 閉状態へと変化させたりする理由は、以下 の通りである。 [0021] Here, as described above, the reason why the ventilation device is normally closed and changed from the closed state to the open state, or is always open and the open state force is changed to the closed state. It is as follows.
たとえば寒いときに閉状態とし、暑くなるにしたがって開状態とする換気装置を、台 所等のように換気扇が装備されて ヽる室内の換気口に設置した場合に、以下のよう な不具合を生じる。すなわち、上記の換気扇を作動させると、室内が負圧となり、隙 間の大きい窓縁等力 外気が入り込み、暖房機等で折角暖めた室内が冷えてしまい 、室内温度を一定に保つことができないという問題を生じる。また、このような換気装 置を設けた換気口は、夏場または暖カ 、ときには開状態となり、このような非密閉状 態でエアコン等を冷房のために作動させた場合は、電力を余分に消費させてしまうこ とになる。 For example, when a ventilator that closes when it is cold and opens as it gets hot is installed at a ventilating room that is equipped with a ventilation fan such as a pedestal, the following problems occur. . In other words, when the ventilation fan is activated, the room becomes negative pressure, the window edge has a large gap, etc. The outside air enters, the room warmed by the heater etc. is cooled, and the room temperature cannot be kept constant. This causes a problem. In addition, a ventilation opening provided with such a ventilation device is sometimes opened in the summer or warm weather. If an air conditioner or the like is operated for cooling in this state, extra power will be consumed.
[0022] 本発明に係るサーモアクチユエータ付き換気装置によれば、寒いときの閉状態、開 状態を適宜選択できる構造であるから、このような換気装置を設けた換気口の設置 位置を任意に選定することができる。たとえば寒いときに開状態となる換気装置を、 台所等において換気扇の側に設けたとしても、外気を最短距離で排気することが可 能であるから、室内温度を一定に保つことができる。また、上記の換気口では、夏場 に閉状態することができるから、省エネルギ効果を図ることが可能となる。  [0022] According to the ventilator with a thermoactuator according to the present invention, since it has a structure in which a closed state and an open state can be appropriately selected when it is cold, the installation position of the ventilation port provided with such a ventilator is arbitrary. Can be selected. For example, even if a ventilator that is open when it is cold is provided on the side of a ventilation fan in a kitchen or the like, the outside air can be exhausted in the shortest distance, so that the room temperature can be kept constant. Further, since the above vent can be closed in summer, an energy saving effect can be achieved.
換言すれば、本発明に係るサーモアクチユエータ付き換気装置では、サーモアクチ ユエータであるサーモエレメントの感温度を室内あるいは屋外にすることや、寒 、とき に閉状態、寒いときに開状態の切り替えを容易に行えるものであり、適宜選択すれば よいものである。  In other words, in the ventilator with a thermoactuator according to the present invention, the thermosensitive temperature of the thermoactuator, which is a thermoactuator, can be set indoors or outdoors, and can be switched between a cold, sometimes closed state, and an open state when cold. It can be easily done and can be selected as appropriate.
発明の効果  The invention's effect
[0023] 以上説明したように本発明に係るサーモアクチユエータ付き換気装置によれば、換 気口に設けた蓋体の開閉方向を、開状態カも閉状態、あるいは閉状態力も開状態と いうように任意の方向に切り替えることが、きわめて簡単に行える。すなわち、前記サ 一モアクチユエータの作動方向及び設置位置は固定で、蓋体の駆動部への組付け 姿勢を変更するだけで、上記のような開閉方向が任意に選択できるから、余分な新 規部品を追加する等が不要であり、また簡単な組付け作業でよいから、コスト的にも 安価である等の種々優れた効果がある。  [0023] As described above, according to the ventilator with a thermoactuator according to the present invention, the open / close direction of the lid provided at the ventilation port is set to the open state or the closed state, or the closed state force is set to the open state. Thus, switching to an arbitrary direction can be performed very easily. In other words, the operating direction and installation position of the thermoactuator are fixed, and the opening and closing direction as described above can be arbitrarily selected simply by changing the assembly position of the lid to the drive unit. Since there is no need to add, etc., and a simple assembling work is sufficient, there are various excellent effects such as low cost.
[0024] また、蓋体の回動軸である支軸部は、開閉状態の変化する方向がいずれであって も共通に使用でき、その位置は切り替えによっては変更する必要がないから、装置全 体の小型化が可能で、形状も簡単である。  [0024] In addition, the support shaft portion, which is the rotation shaft of the lid, can be used in common regardless of the direction in which the open / close state changes, and its position does not need to be changed by switching. The body can be downsized and the shape is simple.
さらに、ォーノリフト時にも、ホルダ部材等に設けたロック部へのロックとリテーナ部 材に設けたコイルばね等の付勢力によって対処することができるのである。  Furthermore, even during the hono-lift, it is possible to cope with the urging force of the lock to the lock portion provided on the holder member and the coil spring provided on the retainer member.
[0025] また、本発明によれば、温度が上昇するにつれて開状態から閉状態に変化する設 定では、上記のような開度調整機能が防火機能を兼ね備えているから、構成部品点 数の必要以上の増加を招くことなぐ少ない設定変更によって、たとえば換気口を開 閉するにあたって、細かい開閉動作を可能とし、温度に応じた必要な流量特性を簡 単〖こ得ることができる。しかも、本発明による防火機能を兼ね備えた開度調整機能で は、何らかの外的要因によって防火機能が働き、全閉状態となったときでもその復旧 力 Sきわめて簡単に行える。 [0025] Further, according to the present invention, in the setting that changes from the open state to the closed state as the temperature rises, the opening adjustment function as described above also has a fire prevention function. For example, opening a ventilation opening with a small setting change that does not increase more than necessary. When closing, it can be opened and closed finely, and the required flow characteristics according to temperature can be easily obtained. Moreover, the opening degree adjusting function having the fire prevention function according to the present invention can be performed very easily even when the fire prevention function is activated due to some external factor and becomes fully closed.

The configuration of is described below.
すなわち、全体を符号 10で示すサーモアクチユエータ付き換気装置は、図 1およ び図 2に示されるように、フランジ 11aを有する円筒体 11を備え、この円筒体 11の内 部が通気口 12となっている。  That is, the ventilator with a thermoactuator denoted as a whole by reference numeral 10 includes a cylindrical body 11 having a flange 11a as shown in FIGS. 1 and 2, and the inside of the cylindrical body 11 has a vent hole. 12

It is an assembling part of the ventilation drive part 20 including a certain thermo element 23. Indoor and outdoor ventilation is provided through openings formed between the radial ribs 14. The rib 14 is provided with a filter 14a so that dust and impurities in the air passing through the cylindrical body 11 can be removed.
[0029] 前記換気駆動部 20は、円筒状受け部 13内に組み込まれるコイルばね 21と、このコ ィルばね 21により弾性支持されることによりサーモエレメント 23の作動により蓋体 30 , 30を開閉動作させるためのリンク機構を構成するリテーナ部材 22と、このリテーナ 部材 22および前記サーモエレメント 23を保持した状態で前記円筒状受け部 13側に 組み付けられるホルダ部材 24とを備えて 、る。このホルダ部材 24は係止爪 24aを有 し、この係止爪 24aを前記円筒状受け部 13の外側に形成される係止溝部 24bに係 止させることにより、構成部品を保持した状態で前記円筒状受け部 13に組み付けら れるようになっている。 The ventilation drive unit 20 opens and closes the lids 30 and 30 by the operation of the thermo element 23 by being elastically supported by the coil spring 21 incorporated in the cylindrical receiving unit 13 and the coil spring 21. Retainer member 22 constituting a link mechanism for operation, and the retainer A holder member 24 assembled to the cylindrical receiving portion 13 side in a state where the member 22 and the thermo element 23 are held. The holder member 24 has a locking claw 24a, and the locking claw 24a is locked to a locking groove 24b formed on the outside of the cylindrical receiving portion 13 so that the component parts are held in a state of being held. It can be assembled to the cylindrical receiving part 13.
[0030] 前記リテーナ部材 22は、図 2に示すように、左、右両側に膨出して形成されたカム 部 27, 27を有し、これらのカム部 27, 27の前記ホルダ部材 24側の面力 後述する 蓋体 30の係合端となる可動軸 33に対応する被係合部であるカム面 27a, 27aを形 成するように構成されている。これらのカム面 27a, 27aは、該リテ一ナ部材 22の本体 部分力 外方端に行くに従って前記円筒状受け部 13方向に向かって斜めに傾斜す る傾斜面として形成されて 、る。  [0030] As shown in Fig. 2, the retainer member 22 has cam portions 27, 27 formed to bulge on both the left and right sides, and the cam portions 27, 27 are arranged on the holder member 24 side. Surface force It is configured to form cam surfaces 27a and 27a which are engaged portions corresponding to the movable shaft 33 which becomes an engagement end of the lid 30 which will be described later. These cam surfaces 27a, 27a are formed as inclined surfaces that are inclined obliquely toward the cylindrical receiving portion 13 toward the outer end of the main body partial force of the retainer member 22.
また、これらのカム部 27, 27は、糸且付け状態では、前記円筒状受け部 13の外周部 に形成したすり割り部 13a, 13aに後述するサーモエレメント 23を構成するピストン 25 の進退動作に合わせて進退動作可能に嵌め込まれた状態となっている。  In addition, these cam portions 27 and 27 are used to advance and retract a piston 25 that constitutes a thermo element 23 to be described later in a slit portion 13a and 13a formed on the outer peripheral portion of the cylindrical receiving portion 13 in a thread tightening state. At the same time, it is in a state where it can be moved forward and backward.
[0031] 前記サーモエレメント 23は、周知の通り、温度影響によって膨張、収縮するワックス 等の熱膨張体を有し、該熱膨張体の膨張または収縮によって進退動作されるピスト ン 25の動きで、前記リテーナ部材 22をコイルばね 21の付勢力に抗して進退動作さ せるように構成されている。  [0031] As is well known, the thermo element 23 has a thermal expansion body such as wax that expands and contracts under the influence of temperature, and the movement of the piston 25 that is advanced and retracted by expansion or contraction of the thermal expansion body. The retainer member 22 is configured to move forward and backward against the urging force of the coil spring 21.
[0032] 図中 30, 30はそれぞれ半円板状を呈して前記通気口 12を開閉する、いわゆるバ タフライバルブを構成する蓋体で、この蓋体 30は、前記ホルダ部材 24の左、右に所 定間隔をお 、て延設されたアーム部の先端に固定軸 31 , 31を介して回動自在に軸 支されている。これらの固定軸 31, 31は、蓋体 30に形成されているコ字状切り欠き の上縁と下縁に設けられ、またこれらの固定軸 31に卷回されたねじりばね 32 (図 2、 図 3参照)により蓋体 30を閉状態となる方向に付勢されている。  [0032] In the figure, 30 and 30 are lid bodies constituting a so-called butterfly valve, each of which has a semicircular shape and opens and closes the vent hole 12. The lid body 30 is the left of the holder member 24, It is pivotally supported via fixed shafts 31 and 31 at the tip of an arm portion extending at a predetermined interval to the right. These fixed shafts 31, 31 are provided at the upper and lower edges of the U-shaped notches formed in the lid body 30, and the torsion springs 32 wound around the fixed shafts 31 (Fig. 2, The lid 30 is urged in the direction of closing by FIG.
[0033] また、前記蓋体 30は、図 2、図 3、図 4に示すように、前記固定軸 31に近接する部 分に該固定軸 31と偏心した状態の可動軸 33を有している。この可動軸 33は、この 実施形態では、蓋体 30から延設されたアーム部の先端に設けられ、組付け状態に おいて前記カム部 27のカム面 27aに選択的に当接される係合端として構成されてい る。 Further, as shown in FIGS. 2, 3, and 4, the lid 30 has a movable shaft 33 in an eccentric state with respect to the fixed shaft 31 at a portion close to the fixed shaft 31. Yes. In this embodiment, the movable shaft 33 is provided at the tip of an arm portion extending from the lid body 30 and selectively contacts the cam surface 27a of the cam portion 27 in the assembled state. Constructed as an end The
[0034] ここで、図 2中右側の蓋体 30は閉状態である場合を、図中左側の蓋体 30は開状態 である場合を示すが、実際には、蓋体 30, 30は同時に開状態または閉状態となるよ うに連動して動作することは勿論である。なお、この図 2において、左、右の蓋体 30に おける固定軸 31と可動軸 33との位置関係が逆になつている力 これは、左側の蓋体 30を、後述する図 5、図 6で説明する蓋体 30の開閉方向を逆にした場合の取付け姿 勢を説明するためのものであって、図 1〜図 4の場合での左側の蓋体 30では、可動 軸 33が蓋体の手前側の表面側に突出して位置することになるのである。  Here, the right lid 30 in FIG. 2 shows a closed state, and the left lid 30 in the figure shows an open state. It goes without saying that they operate in conjunction with each other so as to be in an open state or a closed state. Note that in FIG. 2, the force in which the positional relationship between the fixed shaft 31 and the movable shaft 33 in the left and right lid bodies 30 is reversed. 6 is for explaining the mounting posture when the opening / closing direction of the lid 30 described in FIG. 6 is reversed. In the lid 30 on the left side in the case of FIGS. 1 to 4, the movable shaft 33 is a lid. It is located so as to protrude from the front side of the body.
[0035] 前記ホルダ部材 24の左、右側部には、図 2、図 3 (d)に示すように、蓋体 30の閉状 態において、前記蓋体 30の固定軸 31よりも室内側に偏心している可動軸 33が当接 することで係止されるロック部 35が設けられている。これらのロック部 35は、蓋体 30が 換気口 12を閉じた状態でそれ以上の回動を規制するためのものであり、ォーノリフト 時の蓋体 30の動きを吸収することができるように構成されて!、る。  [0035] As shown in Figs. 2 and 3 (d), the left and right side portions of the holder member 24 are biased to the indoor side with respect to the fixed shaft 31 of the lid 30 when the lid 30 is closed. A lock portion 35 is provided to be locked when the centering movable shaft 33 contacts. These locking parts 35 are for restricting further rotation of the lid 30 with the ventilation port 12 closed, and are configured to absorb the movement of the lid 30 during the onolift. Being! RU
[0036] 以上の構成において、サーモエレメント 23、ピストン 25、リテーナ部材 22、コイルば ね 21を内設した状態でホルダ部材 24を、換気口 12内の受け部 13に組付けし、換気 駆動部 20を組み立てるとともに、蓋体 30を固定軸 31によりホルダ部材 24に軸支し、 ねじりばね 32の付勢力で可動軸 33を前記リテーナ部材 22のカム部 27のカム面 27a に当接させると、図 1の実線で示す状態、図 3 (a)、図 4 (a)で示す状態となる。  [0036] In the above configuration, the holder member 24 is assembled to the receiving portion 13 in the ventilation port 12 with the thermo element 23, the piston 25, the retainer member 22, and the coil spring 21 installed therein, and the ventilation drive unit 20 is assembled, and the lid 30 is pivotally supported on the holder member 24 by the fixed shaft 31, and the movable shaft 33 is brought into contact with the cam surface 27a of the cam portion 27 of the retainer member 22 by the urging force of the torsion spring 32. The state shown by the solid line in FIG. 1, the state shown in FIG. 3 (a) and FIG. 4 (a).
[0037] この状態において、屋外の外気温度中に臨んでいるサーモエレメント 23の熱膨張 体が、外気温度の温度上昇によって膨張し、ピストン 25を突出する方向に押し出すと 、リテーナ部材 22はコイルばね 21の付勢力に抗して反ホルダ部材 24側に移動する 。すると、カム部 27のカム面 27aに当接している可動軸 33は、図 3 (b)、図 3 (c)、並 びに図 4 (b)、図 4 (c)に示すように、カム面 27aの動きに従ってねじりばね 32の付勢 力で移動し、結果として蓋体 30が、前記外気温度に従って閉動作することになる。  [0037] In this state, when the thermal expansion body of the thermo-element 23 facing the outdoor outdoor temperature expands due to a rise in the outdoor air temperature and pushes the piston 25 in a protruding direction, the retainer member 22 becomes a coil spring. Moves to the side opposite to the holder member 24 against the urging force of 21. Then, the movable shaft 33 that is in contact with the cam surface 27a of the cam portion 27 is moved into the cam as shown in FIGS. 3 (b), 3 (c), 4 (b), and 4 (c). According to the movement of the surface 27a, the torsion spring 32 moves, and as a result, the lid 30 is closed according to the outside air temperature.
[0038] さらに、外気温度が温度上昇して熱膨張体が膨張し、ピストン 25を蓋体 30の閉状 態以上に押し出したときには、図 3 (d)、図 4 (d)に示すように、可動軸 33は、カム面 2 7aから離脱した位置に至り、非係合状態となるとともに、ホルダ部材 24に設けたロッ ク部 35に当接してロックされ、閉状態を維持する一方、ピストン 25の押出しは、リテー ナ部材 22の動きで吸収されることなる。 [0038] Further, when the outside temperature rises and the thermal expansion body expands and the piston 25 is pushed beyond the closed state of the lid body 30, as shown in FIGS. 3 (d) and 4 (d), The movable shaft 33 reaches a position where it is detached from the cam surface 27a, and is in a non-engaged state and is locked by being brought into contact with a lock portion 35 provided on the holder member 24, while maintaining a closed state. The extrusion of the retainer It is absorbed by the movement of the member 22.
[0039] また、この実施形態のように、所定温度以上である場合に、可動軸 33のカム面 27a への係合、つまり当接状態を離脱させ、蓋体 30を閉状態とする構成では、火災等の 非常時に対処することができることになる。すなわち、サーモエレメント 23が異常な温 度を感知し、前記ピストン 25の動きでリテーナ部材 22が移動し、可動軸 33がカム面 27aから離脱した位置に至って非当接状態になると、前記換気口 12が完全に閉塞さ れて、火災時の防火機能を発揮できるように構成されている。これは、換気口 12が閉 じられることで、火炎の通り道を塞 、で延焼を防ぐことができるからである。  [0039] Further, as in this embodiment, when the temperature is equal to or higher than a predetermined temperature, the engagement of the movable shaft 33 with the cam surface 27a, that is, the contact state is released, and the lid 30 is closed. It will be possible to cope with an emergency such as a fire. That is, when the thermo-element 23 senses an abnormal temperature, the retainer member 22 is moved by the movement of the piston 25, and the movable shaft 33 reaches the position where it is detached from the cam surface 27a and is in a non-contact state, the ventilation port 12 is completely closed so that it can provide fire protection in the event of a fire. This is because by closing the ventilation opening 12, the passage of the flame can be blocked and the spread of fire can be prevented.
[0040] ここで、この実施形態では、上述したカム部 27のカム面 27aは、前記サーモエレメ ント 23の動きで蓋体 30を開閉動作させるための回動動作を制御するところであり、任 意の回動動作量を制御できるように構成するとよい。すなわち、蓋体 30を開状態から 閉じる際に、低温状態ではゆっくり閉じ、高温になるにしたがって急に閉じるようにし たり、これとは逆の特性となるように構成することができるのである。要は、カム面形状 を任意に選択して形成すればょ ヽ。  [0040] Here, in this embodiment, the cam surface 27a of the above-described cam portion 27 controls the rotation operation for opening and closing the lid body 30 by the movement of the thermoelement 23, and is optional. It is good to comprise so that rotation amount can be controlled. That is, when the lid 30 is closed from the open state, it can be configured so that it closes slowly in a low temperature state, closes suddenly as the temperature rises, or has the opposite characteristics. In short, it is only necessary to select the cam surface shape.
[0041] 以上の構成によるサーモアクチユエータ付き換気装置 10によれば、外気温度が低 く寒い時に換気口 12を開き、暑い時に閉じるようにすることができる力 これとは逆に 、外気温度が低くて寒い時に換気口 12を閉じ、暑い時に開くように構成することが求 められることちある。  [0041] According to the ventilator with a thermoactuator 10 configured as described above, the force that can open the vent 12 when the outside air temperature is low and it is cold and close it when the outside air is hot. It may be required to be configured to close the vent 12 when it is cold and cold and open when it is hot.
[0042] 図 5および図 6は上述した図 1ないし図 4とは蓋体 30の開閉方向を逆にした場合を 示すものである。  FIG. 5 and FIG. 6 show the case where the opening / closing direction of the lid 30 is reversed with respect to FIGS. 1 to 4 described above.
すなわち、前述した図 1ないし図 4の取付け状態において、蓋体 30をホルダ部材 2 4力ら取り外し、図 5、図 6に示すように、蓋体 30のホルダ部材 24への取付け向きを 逆にし、またコイルばね 32による付勢方向を、上述した図 1ないし図 4の例とは逆に、 蓋体 30を閉じた状態で、可動軸 33を固定軸 31回りで屋外側力も室内側に向って回 動させる方向、つまり図 6中時計方向とするよい。  That is, in the mounting state shown in FIGS. 1 to 4, the lid 30 is removed from the holder member 24, and the mounting direction of the lid 30 on the holder member 24 is reversed as shown in FIGS. In addition, contrary to the examples of FIGS. 1 to 4 described above, the urging direction by the coil spring 32 is such that, with the lid 30 closed, the movable shaft 33 is rotated around the fixed shaft 31 and the outdoor side force is also directed indoors. The direction to be rotated, that is, the clockwise direction in FIG.
[0043] なお、この図 5、図 6のようにするには、前述したように図 2における蓋体 30の取付け 姿勢を、この図 2中の左側の蓋体 30のように、可動軸 33が蓋体 30の背面側の表面 側に突出して位置するようにすればよいのである。このとき、図 2中の右側の蓋体 30 は、図示の姿勢とは逆向きにすることは言うまでもない。 5 and FIG. 6, as described above, the mounting position of the lid 30 in FIG. 2 is changed to the movable shaft 33 as in the left lid 30 in FIG. It is only necessary that the protrusion protrudes from the front surface side of the lid 30. At this time, the right lid 30 in FIG. Needless to say, the orientation is opposite to the illustrated orientation.
[0044] このようにすると、図 5、図 6に示すように、蓋体 30は、常時は換気口 12を閉じる状 態にあり、温度上昇に伴ってサーモエレメント 23の働きで図 6 (b)、(c)で示すように、 徐々に換気口 12を開くように動作されるのである。  In this manner, as shown in FIG. 5 and FIG. 6, the lid 30 is normally in a state of closing the vent 12 and the thermoelement 23 acts as the temperature rises, as shown in FIG. As shown in (c) and (c), the air vent 12 is gradually opened.
このときも、所定温度以上のピストン 25の動きは、図 6 (d)に示すように、リテーナ部 材 22には伝わる力 蓋体 30の開動作は、可動軸 33のロック部 35への当接によりロッ クされるようになつている。  At this time, as shown in FIG. 6 (d), the movement of the piston 25 exceeding the predetermined temperature is transmitted to the retainer member 22. The opening operation of the lid 30 is applied to the lock portion 35 of the movable shaft 33. It is locked by contact.
[0045] そして、このような構成によれば、サーモエレメント 23を含めた換気装置 10の構成 部品はそのままに、蓋体 30の糸且付け方向を変えるだけで、蓋体 30の開閉動作を逆 に構成することができるのであり、新規部品は不要で、コスト低減が図れるば力りでな ぐ組立ても容易であり、し力も蓋体 30の回転軸 31等の位置は同じであるから、装置 10の大型化を招くおそれはなぐまた形状も簡単である等の利点がある。  [0045] According to such a configuration, the opening / closing operation of the lid 30 can be reversed simply by changing the thread attachment direction of the lid 30 while leaving the components of the ventilation device 10 including the thermo element 23 unchanged. Since no new parts are required and the cost can be reduced, it is easy to assemble without force, and the position of the rotating shaft 31 etc. of the lid 30 is the same. There is an advantage that the size of 10 is not increased and the shape is simple.
[0046] ここで、上記の実施形態では、熱膨張体を内蔵するサーモエレメント 23の感温部を 、蓋体 30の固定軸 31よりも屋外側に設置した構造としているが、前記固定軸 31より も室内側に設置してもよい。  Here, in the above-described embodiment, the thermosensitive part of the thermo-element 23 incorporating the thermal expansion body has a structure installed on the outdoor side from the fixed shaft 31 of the lid 30. However, the fixed shaft 31 It may be installed indoors.
[0047] 図 7ないし図 12は本発明の第 2の実施形態を示すものであり、これらの図において 前述した実施形態による換気装置 10と同一または相当する部分には同一番号を付 して説明は省略する。また、これらの図において、図 7ないし図 10は蓋体 30を常時は 閉状態とし、この閉状態力も開状態に変化させる場合を、図 11、図 12は蓋体 30を常 時は開状態とし、この開状態力 閉状態へと変化させる場合を示す。  FIGS. 7 to 12 show a second embodiment of the present invention. In these drawings, the same or corresponding parts as those in the ventilator 10 according to the embodiment described above are denoted by the same reference numerals. Is omitted. Also, in these drawings, FIGS. 7 to 10 show the case where the lid 30 is normally closed and this closing force is also changed to the open state, and FIGS. 11 and 12 are the lid 30 normally open. The case where the open state force is changed to the closed state is shown.
[0048] なお、上記の図 8においても、前述した図 2と同様に、図中右側の蓋体 30は閉状態 である場合を、図中左側の蓋体 30は開状態である場合を示すが、実際には、蓋体 3 0, 30は同時に開状態または閉状態となるように連動して動作することは言うまでもな い。さらに、この図 8においても、左、右の蓋体 30における固定軸 31と可動軸 33との 位置関係が逆になつている力 これは、左側の蓋体 30を、後述する図 11、図 12で説 明する蓋体 30の開閉方向を逆にした場合の取付け姿勢を示すものであって、図 7〜 図 10の場合での左側の蓋体 30では、可動軸 33が蓋体の手前側の表面側に突出し て位置することになるのである。 [0049] この実施形態でのサーモアクチユエータ付き換気装置 10によれば、換気駆動部 20 内で円筒状受け部 13とホルダ部材 24との間に組み込む部品のうち、サーモアクチュ エータであるサーモエレメント 23とピストン 25とを、前述した実施形態とは逆に、ホル ダ部材 24側にピストン 25を押し出すように組み込んで 、る。 FIG. 8 also shows the case where the right lid 30 in the figure is in the closed state, and the case where the left lid 30 in the figure is in the open state, as in FIG. 2 described above. However, it goes without saying that the lid bodies 30 and 30 actually operate in conjunction with each other so that they are simultaneously opened or closed. Further, in FIG. 8 as well, the force in which the positional relationship between the fixed shaft 31 and the movable shaft 33 in the left and right lid bodies 30 is reversed. 12 shows the mounting posture when the opening and closing direction of the lid 30 described in 12 is reversed. In the lid 30 on the left side in the case of FIGS. 7 to 10, the movable shaft 33 is located in front of the lid. It is located so as to protrude from the surface side. [0049] According to the ventilator 10 with the thermoactuator in this embodiment, the thermostat which is a thermoactuator among the parts incorporated between the cylindrical receiving part 13 and the holder member 24 in the ventilation drive part 20 is provided. Contrary to the above-described embodiment, the element 23 and the piston 25 are assembled so as to push the piston 25 toward the holder member 24 side.
このような構成では、たとえば室内側の温度をサーモエレメント 23で検知し、該温 度上昇にしたがって、換気口 12を開状態カも閉状態へと開閉制御することができる。  In such a configuration, for example, the temperature inside the room can be detected by the thermo element 23, and the vent 12 can be controlled to be opened and closed as the temperature rises.
[0050] 図中 40はこの実施形態でのリテーナ部材で、このリテーナ部材 40は、左、右側に 二股状カム部 41, 41を有し、この二股状カム部 41の内側が前記蓋体 40に一体的に 設けた可動軸 33に当接するカム面 41aを形成するように構成されている。  In the figure, reference numeral 40 denotes a retainer member in this embodiment. The retainer member 40 has bifurcated cam portions 41, 41 on the left and right sides, and the inside of the bifurcated cam portion 41 is the lid 40. The cam surface 41a is formed so as to contact the movable shaft 33 provided integrally therewith.
前記蓋体 30側の可動軸 33は、蓋体 30に設けた固定軸 31, 31とクランク状を呈す るように、蓋体 30を閉じた状態で該固定軸 31よりも屋外側に位置して一体的に設け られている。勿論、これらの軸 31 , 33は軸芯がずれて位置するように形成されている 。なお、第 1の実施形態でのねじりばね 32は不要である。  The movable shaft 33 on the lid body 30 side is located on the outdoor side of the fixed shaft 31 with the lid body 30 closed so as to form a crank shape with the fixed shafts 31 and 31 provided on the lid body 30. Are integrated. Of course, the shafts 31 and 33 are formed so that the shaft centers are shifted. Note that the torsion spring 32 in the first embodiment is not necessary.
[0051] 前記サーモエレメント 23、ピストン 25、リテーナ部材 40は、受け部 13との間にコィ ルばね 21を介在させ、ホルダ部材 24により保持された状態で組み立てられて 、る。 なお、図中 45はリテーナ部材 40をホルダ部材 24側で弾性支持するコイルばねであ る。  [0051] The thermo element 23, the piston 25, and the retainer member 40 are assembled in a state in which the coil spring 21 is interposed between the thermo element 23, the piston 25, and the retainer member 40 and is held by the holder member 24. In the figure, 45 is a coil spring that elastically supports the retainer member 40 on the holder member 24 side.
[0052] さらに、円筒状受け部 13の先端は、図 9 (d)に示すように、リテーナ部材 40を係止 するロック部 43であり、ピストン 25の押出し量を制御するためのォーノリフト吸収機構 を構成するところである。  [0052] Further, as shown in FIG. 9 (d), the tip of the cylindrical receiving portion 13 is a lock portion 43 for locking the retainer member 40, and an onolift absorbing mechanism for controlling the push-out amount of the piston 25. It is the place which constitutes.
[0053] 以上の構成において、サーモエレメント 23、ピストン 25、リテーナ部材 40、コイルば ね 45を内設した状態でホルダ部材 24、コイルばね 21を、換気口 12内の受け部 12 に組付けし、換気駆動部 20を組み立てるとともに、蓋体 30を固定軸 31によりホルダ 部材 24に軸支して可動軸 33を前記リテーナ部材 40の二股状カム部 41のカム面 41 aに当接させると、図 7の実線で示す状態、図 9 (a)、図 10 (a)で示す状態となる。  [0053] In the above configuration, the holder member 24 and the coil spring 21 are assembled to the receiving portion 12 in the ventilation port 12 with the thermo element 23, the piston 25, the retainer member 40, and the coil spring 45 installed therein. In addition to assembling the ventilation drive unit 20, when the lid 30 is pivotally supported on the holder member 24 by the fixed shaft 31, and the movable shaft 33 is brought into contact with the cam surface 41a of the bifurcated cam portion 41 of the retainer member 40, The state shown by the solid line in FIG. 7, the state shown in FIG. 9 (a) and FIG. 10 (a).
[0054] この状態において、室内温度に曝されているサーモエレメント 23の熱膨張体力 温 度上昇によって膨張し、ピストン 25を突出する方向に押し出すと、リテーナ部材 40、 サーモエレメント 23はコイルばね 21の付勢力に抗して反ホルダ部材 24側に相対的 に移動する。すると、二股状カム部 41のカム面 41aに当接している可動軸 33は、図 9 (b)、図 9 (c)、並びに図 10 (b)、図 10 (c)〖こ示すように、カム面 41aの動きに従って 相対的に移動し、結果として蓋体 30が、前記室内温度に従って閉状態力も開動作 すること〖こなる。 In this state, when the thermal expansion body force of the thermoelement 23 exposed to the room temperature expands due to the temperature rise and pushes the piston 25 in the protruding direction, the retainer member 40 and the thermoelement 23 Relative to the anti-holder member 24 side against the biasing force Move to. Then, the movable shaft 33 in contact with the cam surface 41a of the bifurcated cam portion 41 is shown in FIGS. 9 (b), 9 (c), 10 (b), and 10 (c). As a result, the lid body 30 moves relatively according to the movement of the cam surface 41a, and as a result, the lid 30 also opens the closed state force according to the room temperature.
[0055] さらに、室内温度が温度上昇して熱膨張体が膨張し、ピストン 25を蓋体 30の開状 態以上に押し出したときには、図 9 (d)に示すように、リテーナ部材 40が、円筒状受け 部 13側のロック部 43に当接してロックされることで、開状態を維持することになる。こ のとき、ピストン 25が更に押し出されても、このリテーナ部材 40はその状態を維持す るとともに、内部のサーモエレメント 23がコイルばね 21の付勢力に抗して移動するこ とでその移動量は吸収されることになる。なお、リテーナ部材 40は、コイルばね 45の 付勢力により常時はサーモエレメント 23の動きに追随して移動し、オーバリフト時に はリテーナ部材 40が係止され、さらなるサーモエレメント 23の移動によるリテーナ部 材 40の動きをコイルばね 45が吸収するように構成されて!、る。  [0055] Further, when the indoor temperature rises and the thermal expansion body expands and the piston 25 is pushed out beyond the open state of the lid body 30, as shown in FIG. The open state is maintained by contacting and locking to the lock portion 43 on the cylindrical receiving portion 13 side. At this time, even if the piston 25 is further pushed out, the retainer member 40 maintains its state, and the inner thermo element 23 moves against the urging force of the coil spring 21 so that the movement amount is maintained. Will be absorbed. The retainer member 40 always moves following the movement of the thermo element 23 due to the urging force of the coil spring 45, and the retainer member 40 is locked at the time of overlift, and the retainer member 40 is moved by the further movement of the thermo element 23. The coil spring 45 is configured to absorb 40 movements! RU
[0056] なお、上述した二股状カム部 41のカム面 41aは、前記サーモエレメント 23の動きで 蓋体 30を開閉動作させるための回動動作を制御するところであり、任意の回動動作 量を制御できるように構成するとよいものである。すなわち、蓋体 30を開状態から閉じ る際に、低温状態ではゆっくり閉じ、高温になるにしたがって急に閉じるようにしたり、 これとは逆の特性となるように構成することができる。要は、カム面形状を任意に選択 して形成すればよい。  Note that the cam surface 41a of the bifurcated cam portion 41 described above controls a pivoting operation for opening and closing the lid 30 by the movement of the thermo element 23, and an arbitrary amount of pivoting operation is controlled. It should be configured so that it can be controlled. That is, when the lid 30 is closed from the open state, it can be configured so that it closes slowly in the low temperature state and closes suddenly as the temperature rises, or has the opposite characteristics. In short, the cam surface shape may be arbitrarily selected and formed.
また、この実施形態では、カム面 41aを二股状カム部 41に形成することで、蓋体 30 をカム面への当接方向に付勢する必要がな!、ように構成して 、るが、これに限定され な!ヽことは言うまでもな!/ヽ。  In this embodiment, the cam surface 41a is formed on the bifurcated cam portion 41, so that it is not necessary to urge the lid 30 in the direction of contact with the cam surface! Not limited to this! Needless to say! / ヽ.
[0057] 以上の実施形態での構成によれば、サーモアクチユエータ付き換気装置 10におい て、室内温度が低く寒い時に換気口 12を閉じ、暑い時に開くようにすることができる 力 これとは逆に、室内温度が低くて寒い時に換気口 12を開き、暑い時に閉じるよう に構成することが求められることもある。  [0057] According to the configuration in the above embodiment, in the ventilator 10 with the thermoactuator, the force that can close the ventilation opening 12 when the room temperature is low and it is cold and open it when it is hot. Conversely, it may be required that the vent 12 be opened when the room temperature is cold and cold, and closed when it is hot.
[0058] 図 11および図 12は上述した図 7ないし図 10とは蓋体 30の開閉方向を逆にした場 合を示す。すなわち、前述した図 7ないし図 10の取付け状態において、蓋体 30をホ ノレダ咅材 24力ら取り外し、図 11、図 12に示すように、蓋体 30のホノレダ咅材 24への 取付け向きを、蓋体 30を閉じた状態で固定軸 31よりも室内側に位置させる方向とす ればよい。 FIGS. 11 and 12 show a case where the opening / closing direction of the lid 30 is reversed from that of FIGS. 7 to 10 described above. That is, in the above-described attachment state shown in FIGS. Remove the Noreda rod 24, and as shown in Fig. 11 and Fig. 12, the mounting direction of the lid 30 to the holeder rod 24 is positioned more indoor than the fixed shaft 31 with the lid 30 closed. The direction may be used.
換言すれば、この図 11、図 12のようにするには、前述したように図 8における蓋体 3 0の取付け姿勢を、この図 8中の左側の蓋体 30のように、可動軸 33が蓋体 30の背面 側の表面側に突出して位置するようにすればよい。このとき、図 8中の右側の蓋体 30 は、図示の姿勢とは逆向きにすることは、前述した第 1の実施の形態での図 2の場合 と同じである。  In other words, as shown in FIGS. 11 and 12, as described above, the mounting position of the lid 30 in FIG. 8 is changed to the movable shaft 33 as in the left lid 30 in FIG. May be positioned so as to protrude from the rear surface side of the lid 30. At this time, it is the same as the case of FIG. 2 in the first embodiment described above that the lid 30 on the right side in FIG.
[0059] このようにすると、図 11、図 12に示すように、蓋体 30は、常時は換気口 12を閉じる 状態にあり、温度上昇に伴ってサーモアクチユエータであるサーモエレメント 23の働 きで図 12 (b)、(c)で示すように、徐々に換気口 12を開くように動作されるのである。 このときも、所定温度以上のピストン 25の動きは、図 12 (d)に示すように、サーモェ レメント 23には伝わる力 リテーナ部材 40、さらには蓋体 30の開動作は、ロック部 43 へのリテーナ部材 40の当接によりロックされるようになっている。  [0059] In this manner, as shown in FIGS. 11 and 12, the lid 30 is normally in a state in which the ventilation opening 12 is closed, and the thermoelement 23, which is a thermoactuator, works as the temperature rises. Thus, as shown in FIGS. 12 (b) and 12 (c), the air vent 12 is gradually opened. At this time, as shown in FIG. 12 (d), the movement of the piston 25 above the predetermined temperature is transmitted to the thermo-element 23.The opening operation of the retainer member 40 and the lid 30 is also applied to the lock part 43. The retainer member 40 is locked by contact.
[0060] そして、このような構成によっても、前述した実施形態と同様に、サーモエレメント 23 を含めた換気装置 10の構成部品はそのままに、蓋体 30の組付け方向を変えるだけ で、蓋体 30の開閉動作を逆に構成することができるのであり、新規部品は不要で、コ スト低減が図れるば力りでなぐ組立ても容易であり、しかも蓋体 30の回転軸 31等の 位置は同じであるから、装置 10の大型化を招くおそれはなぐまた形状も簡単である 等の禾 lj点がある。  [0060] Even with such a configuration, as in the above-described embodiment, the lid body 10 can be changed by simply changing the assembly direction of the lid body 30 without changing the components of the ventilation device 10 including the thermoelement 23. The opening / closing operation of 30 can be reversed, no new parts are required, it is easy to assemble by force if the cost can be reduced, and the position of the rotating shaft 31 etc. of the lid 30 is the same Therefore, there is a risk that the apparatus 10 is not enlarged and the shape is simple.
[0061] また、ここでは、熱膨張体を内蔵するサーモエレメント 23の感温部を、蓋体 30の固 定軸 31よりも室内側に設置した構造としているが、前記固定軸 31よりも屋外側に設 置してちょい。  [0061] Here, the temperature sensing part of the thermo-element 23 containing the thermal expansion body is installed on the indoor side of the fixed shaft 31 of the lid 30. Install it outside.
[0062] 図 13は本発明に係る換気装置の変形例を示す。  FIG. 13 shows a modification of the ventilation device according to the present invention.
すなわち、上述した第 1、第 2の実施形態では、換気装置 10の換気駆動部 20とな るァクチユエータとして、サーモエレメント 23を用いた場合を説明したが、このサーモ エレメント 23の代わりに、サーモアクチユエータとして形状記憶合金を利用したり、さ らにこれに併用して発熱体を設け、外部制御で蓋体 30の開閉制御を任意に行えるよ うに構成してもよい。 That is, in the first and second embodiments described above, the case where the thermo element 23 is used as the activator serving as the ventilation drive unit 20 of the ventilator 10 has been described. However, instead of the thermo element 23, the thermo actuator is used. A shape memory alloy can be used as a user, and in addition to this, a heating element can be provided, and the lid 30 can be opened and closed arbitrarily by external control. You may comprise.
[0063] この実施形態を、前述した第 2の実施形態で用いた換気駆動部 20の構造を基に説 明すると、この実施形態では、円筒状受け部 13内に保持される可動本体 60を備え ている。そして、この可動本体 60にリテーナ部材 40がー体的に組み付けられている 。そして、これらの可動本体 60とリテーナ部材 40とは、コイルばね 21とコイルばね 45 とによって弹性的に支持されて 、る。  [0063] This embodiment will be described based on the structure of the ventilation drive unit 20 used in the second embodiment described above. In this embodiment, the movable body 60 held in the cylindrical receiving portion 13 is provided. It has. The retainer member 40 is physically assembled to the movable body 60. The movable body 60 and the retainer member 40 are inertially supported by the coil spring 21 and the coil spring 45.
[0064] このような構成において、前記円筒状受け部 13側のコイルばね 21またはホルダ 24 側のコイルばね 45を、形状記憶合金で形成し、外気温度あるいは室内温度等といつ た周囲温度で伸縮可能に構成することにより、蓋体 30を任意の開度で開閉制御する ことができるのである。なお、形状記憶合金の代わりにバイオメタル等で形成したもの でもよい。  [0064] In such a configuration, the coil spring 21 on the cylindrical receiving portion 13 side or the coil spring 45 on the holder 24 side is formed of a shape memory alloy, and expands and contracts at an ambient temperature such as the outside air temperature or the room temperature. With this configuration, the lid 30 can be controlled to open and close at an arbitrary opening. In addition, it may be formed of biometal or the like instead of the shape memory alloy.
[0065] さらに、上述した構造において、形状記憶合金で形成した円筒状受け部 13側のコ ィルばね 21またはホルダ 24側のコイルばね 45に近接する部分に、図 13中想像線 で示したように PTCヒータ等の発熱体 62または 61を設けると、蓋体 30の開閉制御を 、さらに任意に行えるという利点がある。すなわち、上記の発熱体 62または 61を、換 気装置 10の近傍に設けたコントローラ、あるいは室内からの遠隔操作によるコント口 ーラを用いて発熱制御できるように構成すれば、前記サーモエレメントを使用した場 合でも同様に、換気口の開閉制御を、周囲温度による場合に併用して、任意に行え るようにすることちでさる。  [0065] Further, in the structure described above, a portion adjacent to the coil spring 21 on the cylindrical receiving portion 13 side or the coil spring 45 on the holder 24 side formed of a shape memory alloy is indicated by an imaginary line in FIG. As described above, when the heating element 62 or 61 such as a PTC heater is provided, there is an advantage that the opening / closing control of the lid 30 can be further arbitrarily performed. That is, if the heat generating element 62 or 61 is configured to be able to control heat generation using a controller provided in the vicinity of the ventilation device 10 or a controller operated remotely from the room, the thermo element can be used. In the same way, the opening and closing control of the ventilation port can be performed arbitrarily in combination with the ambient temperature.
[0066] なお、発熱体 62, 61としては、電気的なヒータであればよぐたとえばァクチユエ一 タに-クロム線を巻き付けたものであってもよいし、 PTCヒータをァクチユエータ近くの 適宜の位置に貼り付けてもよいし、あるいはバイオメタル等の電流を流すことで自己 発熱するような形状記憶合金を用いたものであってもよ 、。  [0066] It should be noted that the heating elements 62 and 61 may be any electric heater, for example, an arcuate heater in which a chrome wire is wound, or a PTC heater at an appropriate position near the activator. It may be affixed to the surface, or it may be a shape memory alloy that self-heats by passing an electric current such as biometal.
[0067] このような構成によれば、構成部品点数が必要最小限であるにもかかわらず、換気 装置の蓋体の開閉制御を任意に行えるものであり、しかも前述したサーモエレメント 付き換気装置 10のようなォーノリフト吸収機能は不要であり、また発熱体 62, 61に 通電することで、ァクチユエ一タが感温、変位作動し、蓋体 30を開閉するまでの応答 速度が速くなるという利点もある。 [0068] なお、本発明は上述した実施形態で説明した構造には限定されず、各部の形状、 構造等を適宜変形、変更し得ることはいうまでもない。 [0067] According to such a configuration, the opening / closing control of the lid of the ventilator can be arbitrarily performed in spite of the minimum number of components, and the ventilator with the thermo element described above 10 Ono-lift absorption function is not required, and the heating element 62, 61 is energized, so that the actuator is sensitive to temperature and displacement, and the response speed until the lid 30 is opened and closed is increased. is there. It should be noted that the present invention is not limited to the structure described in the above-described embodiment, and it goes without saying that the shape and structure of each part can be appropriately modified and changed.
たとえば換気口 12を開閉する部材としては、前述した実施形態でのバタフライバル ブタイプの蓋体 30の形状などに限定されず、種々の変形例が考えられることは言うま でもない。  For example, the member for opening and closing the ventilation port 12 is not limited to the shape of the butterfly valve type lid 30 in the above-described embodiment, and it goes without saying that various modifications can be considered.
[0069] さらに、可動軸 33が当接するカム部 27, 41のカム面 27a, 41aの形状としては、上 記の実施形態で説明したものに限定されず、使用される分野や部位などによって適 宜選択できるものであり、蓋体 30の開度を任意に調整することができる。  [0069] Further, the shape of the cam surfaces 27a, 41a of the cam portions 27, 41 with which the movable shaft 33 abuts is not limited to the shape described in the above embodiment, and may be suitable depending on the field or region used. The opening degree of the lid 30 can be arbitrarily adjusted.
また、外気温度、室内温度のどちらを感温させるかで、サーモエレメント 23と蓋体 3 0の設置向きを任意に変更可能である。  Further, the installation direction of the thermo element 23 and the lid 30 can be arbitrarily changed depending on whether the outside air temperature or the room temperature is sensed.
[0070] さらに、本発明に係るサーモアクチユエータ付き換気装置 10において、サーモアク チユエータとして設けたサーモエレメント 23の感温部に近接する部分に、 PTCヒータ 等の発熱体を設けると、上記の図 13の場合と同様に、蓋体 30の開閉制御を、周囲 温度による場合に併用して任意に行えるという利点を奏することができるのである。す なわち、この発熱体を、換気装置 10の近傍に設けたコントローラ、あるいは室内から の遠隔操作によるコントローラを用いて発熱制御できるようにすれば、換気口の開閉 制御を、周囲温度による場合に併用して任意に行えることになる。  [0070] Further, in the ventilator 10 with a thermoactuator according to the present invention, when a heating element such as a PTC heater is provided in a portion close to the temperature sensing portion of the thermoelement 23 provided as a thermoactuator, the above figure As in the case of 13, the opening / closing control of the lid 30 can be performed arbitrarily in combination with the case of ambient temperature. In other words, if this heating element can be controlled by using a controller provided near the ventilation device 10 or a controller remotely operated from the inside of the room, the opening and closing control of the ventilation port can be controlled according to the ambient temperature. It can be done arbitrarily in combination.
なお、上記の発熱体としては、電気的なヒータであればよぐたとえば-クロム線を 巻き付けたものであってもよいし、 PTCヒータを適宜の位置に貼り付けてもよいし、あ るいは電流を流すことで自己発熱するような形状記憶合金を用いたものであってもよ い。  The heating element may be an electric heater, for example, a chrome wire wrapped around it, or a PTC heater may be attached at an appropriate position, or A shape memory alloy that self-heats when an electric current is passed may be used.
[0071] また、上述した実施形態では、本発明に係るサーモアクチユエータ付き換気装置 1 0を住宅設備用として採用した場合を説明したが、これに限定されず、種々の分野に おける換気装置として用いることができることは言うまでもな 、。  In the above-described embodiment, the case where the thermoactuator-equipped ventilator 10 according to the present invention is used for a home facility has been described. However, the present invention is not limited to this, and the ventilator is used in various fields. Needless to say, it can be used as.
