Description

本発明は、主として天井に設置される空調装置の空気吸込口前面に取り付けて用いられる吸込パネル、およびこれを備えた空調装置に関するものである。   The present invention relates to a suction panel that is used by being attached to a front surface of an air suction port of an air conditioner installed mainly on a ceiling, and an air conditioner including the same.

一般に、天井内に埋設されるか天井下に吊り下げられるタイプの、温度、湿度、空気清浄度等の調整用の空調装置においては、該空調装置の下面に空気吸込口が設けられ、この空気吸込口の前面を覆うようにして吸込グリル等の吸込パネルが取り付けられる。吸込パネルの裏側にはエアフィルタが取り付けられたり、吸込パネルにエアフィルタが一体化されたりして、吸込パネルを通じて空気吸込口から空調装置の内部に取り込まれる空気から埃が取り除かれるようになっている。   In general, in an air conditioner for adjusting temperature, humidity, air cleanliness, etc., which is embedded in the ceiling or suspended under the ceiling, an air suction port is provided on the lower surface of the air conditioner, and this air A suction panel such as a suction grill is attached so as to cover the front surface of the suction port. An air filter is attached to the back side of the suction panel, or an air filter is integrated with the suction panel, and dust is removed from the air taken into the air conditioner from the air suction port through the suction panel. Yes.

このため、裏側にエアフィルタが取りつけられたり、エアフィルタが一体化されたりする吸込パネルの前面には、エアフィルタによって取り除かれた埃が堆積する。そこで、吸込パネルを取り外してエアフィルタに堆積した埃を清掃したり、エアフィルタを新しいものと交換したりする作業を定期的に行う必要がある。   For this reason, the dust removed by the air filter accumulates on the front surface of the suction panel where the air filter is attached to the back side or the air filter is integrated. Therefore, it is necessary to periodically perform an operation of removing the suction panel and cleaning the dust accumulated on the air filter or replacing the air filter with a new one.

また、空調装置の内部の点検やメンテナンスの作業を行う際にも、作業者が空調装置の内部にアクセスできるように吸込パネルを取り外す必要がある。   Also, when performing inspection and maintenance work inside the air conditioner, it is necessary to remove the suction panel so that the operator can access the inside of the air conditioner.

このように吸込パネルを取り外す際には、吸込パネルは空調装置の下面に設けられた空気吸込口の前面を覆うようにして取り付けられているので、吸込パネルの取り外し作業に伴う振動によって、吸込パネルの前面に堆積した埃が空調装置下方の室内に落下してしまう。しかし、空調装置が特に食品工場や飲食店等の室内の天井に設けられている場合には、埃が室内に落下してしまうことは衛生上好ましくない。   When removing the suction panel in this way, the suction panel is attached so as to cover the front of the air suction port provided on the lower surface of the air conditioner. The dust accumulated on the front of the camera falls into the room below the air conditioner. However, when the air conditioner is provided on the ceiling of a room such as a food factory or a restaurant, it is not preferable in terms of hygiene that dust falls into the room.

空調装置の吸込パネルを取り外す際の埃の落下を防止するための仕組みとして、例えば特許文献１に開示された技術が知られている。この技術では、空調装置の下面に設けられた化粧パネルに形成された中央開口の奥部に吸込空気を清浄化するためのフィルタを設け、前記中央開口を両側に吸込口空間を残して塞ぐセンターパネルを設け、前記センターパネルには所定高さの脚部を介して前記フィルタを支持させ、このフィルタと一体的に前記センターパネルを昇降自在となるように形成している。この構成により、センターパネルを空調装置本体から下降させ、センターパネルに支持されたフィルタを低所で取り外して交換あるいは清掃することができる。センターパネルの下降時に振動が発生したとしても、フィルタに付着する埃はセンターパネルの上に落下し、そこに捕集されるので、埃が室内に落下することがない。   For example, a technique disclosed in Patent Document 1 is known as a mechanism for preventing dust from falling when removing a suction panel of an air conditioner. In this technology, a filter for purifying the suction air is provided at the back of the central opening formed on the decorative panel provided on the lower surface of the air conditioner, and the central opening is closed by leaving the suction opening space on both sides. A panel is provided, and the center panel is configured to support the filter via a leg portion having a predetermined height, and the center panel can be moved up and down integrally with the filter. With this configuration, the center panel can be lowered from the air conditioner body, and the filter supported by the center panel can be removed and replaced or cleaned at a low place. Even if vibration occurs when the center panel is lowered, the dust adhering to the filter falls onto the center panel and is collected there, so that the dust does not fall into the room.

特開平１０−１９６９９９号公報JP-A-10-196999

しかし、この方法では、センターパネルを空調装置本体に対して昇降させるため、センターパネルを吊り下げる吊りひもを繰り出したり巻き取ったりするモータやシャフト・プーリなどの複雑な構造が必要となり、空調装置の構造を複雑にするとともに空調装置の価格を上昇させてしまう。また、吊りひもの巻き取りが不完全に行われるたびに空調装置の修理をする必要が生じていた。   However, in this method, in order to raise and lower the center panel with respect to the air conditioner main body, a complicated structure such as a motor and a shaft / pulley that draws and winds a hanging string that suspends the center panel is required. This complicates the structure and increases the price of the air conditioner. Moreover, it has been necessary to repair the air conditioner every time the hanging string is wound incompletely.

本発明は、このような事情に鑑みてなされたものであって、空調装置の空気吸込口前面に取り付けて用いられる吸込パネルにおいて、吸込パネル上に支持されたり吸込パネルに一体化されたりするエアフィルタの清掃、交換や空調装置のメンテナンス等のために吸込パネルを取り外す際に、吸込パネルの表面に堆積した埃の落下を簡単に防止することができる吸込パネル、およびこれを備えた空調装置を提供することを目的とする。   The present invention has been made in view of such circumstances, and in the suction panel used by being attached to the front surface of the air suction port of the air conditioner, the air supported on the suction panel or integrated with the suction panel. A suction panel that can easily prevent the dust accumulated on the surface of the suction panel from dropping when the suction panel is removed for cleaning, replacement of the filter, maintenance of the air conditioner, etc., and an air conditioner equipped with the suction panel The purpose is to provide.

上記課題を解決するために、本発明は以下の手段を採用する。   In order to solve the above problems, the present invention employs the following means.

本発明の第１の態様に係る吸込パネルは、空調装置の空気吸込口前面に取り付けて用いられる吸込パネルであって、前記空気吸込口前面に対して脱着可能となるように略板状に形成され、前記空気吸込口前面に取り付けられた状態で該空気吸込口に取り込まれる空気を通り抜けさせる吸込パネル本体と、前記吸込パネル本体の前面を露出及び隠蔽可能となるように前記吸込パネル本体に対して動作可能に取り付けられた被覆部とを備えている。   The suction panel according to the first aspect of the present invention is a suction panel that is used by being attached to the front surface of the air suction port of the air conditioner, and is formed in a substantially plate shape so as to be removable from the front surface of the air suction port. A suction panel body that allows air to be taken into the air suction port in a state of being attached to the front surface of the air suction port, and the suction panel body so that the front surface of the suction panel body can be exposed and concealed. And a cover portion operably attached thereto.

この吸込パネルによれば、吸込パネル上に支持されたり吸込パネルに一体化されたりするエアフィルタの清掃、交換や空調装置のメンテナンス等の作業を行うために吸込パネルを空調装置の空気吸込口前面から取り外す際に、埃が堆積した吸込パネル本体の前面を予め被覆部で隠蔽するように覆った状態を保ちながら吸込パネル本体を空調装置の空気吸込口前面から取り外すことにより、吸込パネル本体の前面に堆積した埃が空調装置の下方の室内に落下することを簡単に防止できる。   According to this suction panel, the suction panel is installed on the front surface of the air inlet of the air conditioner to perform operations such as cleaning, replacement of the air filter that is supported on the suction panel or integrated with the suction panel, and maintenance of the air conditioner. When removing from the front of the suction panel body, remove the suction panel body from the front of the air intake port of the air conditioner while keeping the front surface of the suction panel body where dust has accumulated so as to be concealed by the cover. It is possible to easily prevent the dust accumulated in the air from falling into the room below the air conditioner.

本発明の第１の態様に係る吸込パネルにおいては、前記吸込パネル本体は略線対称形状に形成され、前記被覆部は、前記吸込パネル本体の前記略線対称形状の対称軸の両側に位置する第１の部分と第２の部分とのうち第１の部分の外周に沿う略コ字形状に形成され、前記吸込パネル本体に対して揺動可能となるように両端部が該吸込パネル本体の外周が前記対称軸と交差する部位に回動自在に取り付けられた枠体と、一端部が前記吸込パネル本体の前記第１の部分の外周に固定され、他端部が前記枠体の中間部に固定された被覆膜とを含み、前記被覆膜はプリーツ状に折り畳み可能に形成され、前記枠体が前記吸込パネル本体の前記第１の部分側に位置するときに該第１の部分の外周と前記枠体の中間部との間に折り畳まれて前記吸込パネル本体の前面を露出させ、前記枠体が前記吸込パネル本体の前記第２の部分側に位置するときに展張されて前記吸込パネル本体の前面を隠蔽するように該吸込パネル本体の前面に沿って延在することが望ましい。   In the suction panel according to the first aspect of the present invention, the suction panel body is formed in a substantially line-symmetric shape, and the covering portions are located on both sides of the substantially line-symmetrical symmetry axis of the suction panel body. The first portion and the second portion are formed in a substantially U shape along the outer periphery of the first portion, and both end portions of the suction panel main body are swingable with respect to the suction panel main body. A frame body rotatably attached to a portion whose outer periphery intersects the symmetry axis, one end portion is fixed to the outer periphery of the first portion of the suction panel body, and the other end portion is an intermediate portion of the frame body And the coating film is formed so as to be foldable into a pleat shape, and the first part is positioned when the frame body is positioned on the first part side of the suction panel body. The suction panel is folded between the outer periphery of the frame and the middle part of the frame Along the front surface of the suction panel body so that the front surface of the body is exposed and is stretched when the frame body is positioned on the second portion side of the suction panel body to conceal the front surface of the suction panel body It is desirable to extend.

本構成によれば、枠体を吸込パネル本体の第１の部分側から第２の部分側に移動させることによって、プリーツ状に形成され第１の部分の外周と枠体の中間部との間に折り畳まれていた被覆膜が展張されて、被覆膜が吸込パネル本体の前面を隠蔽するように吸込パネル本体の前面に沿って延在するようになる。したがって、吸込パネルを空調装置の空気吸込口前面から取り外す際に、簡単な作業で吸込パネル本体の前面を被覆膜で覆い、吸込パネル本体の表面に堆積した埃が空調装置の下方の室内に落下することを簡単に防止できる。   According to this configuration, the frame is moved from the first part side to the second part side of the suction panel main body, thereby forming a pleated shape between the outer periphery of the first part and the intermediate part of the frame body. The covering film that has been folded in is extended so that the covering film extends along the front surface of the suction panel body so as to conceal the front surface of the suction panel body. Therefore, when removing the suction panel from the front surface of the air inlet of the air conditioner, the front surface of the suction panel body is covered with a coating film by a simple operation, and dust accumulated on the surface of the suction panel body is placed in the room below the air conditioner. It can be easily prevented from falling.

また、枠体を吸込パネル本体の第２の部分側から第１の部分側に移動させるとともに、プリーツ状に形成された被覆膜を吸込パネル本体の第１の部分の外周と枠体の中間部との間に折り畳んで収納することによって、被覆膜から吸込パネル本体の前面が露出される。したがって、吸込パネル本体を空調装置の空気吸込口前面に再び取り付ける際に、吸込パネル本体の前面を被覆膜から簡単に露出させることができる。   In addition, the frame body is moved from the second part side of the suction panel body to the first part side, and the coating film formed in a pleat shape is placed between the outer periphery of the first part of the suction panel body and the frame body. The front surface of the suction panel main body is exposed from the coating film by folding and storing between the two. Therefore, when the suction panel body is reattached to the front surface of the air suction port of the air conditioner, the front surface of the suction panel body can be easily exposed from the coating film.

あるいは、前記吸込パネル本体は略長方形状に形成され、前記被覆部は、前記吸込パネル本体の互いに対向する二辺にそれぞれ沿うようにして取り付けられた一対の巻取軸と、両端部が前記一対の巻取軸にそれぞれ巻き付けられた状態で前記吸込パネル本体の前面に沿って延在する被覆膜とを含み、前記被覆膜は、前記吸込パネル本体の前面を露出させるように形成された露出孔を備える露出部と、前記吸込パネル本体の前面を隠蔽するように形成された隠蔽部とを備え、前記隠蔽部が前記一対の巻取軸の一方に巻き付けられているとき前記露出部の前記露出孔は前記吸込パネル本体の前面の略全体を露出させ、前記露出部が前記一対の巻取軸の他方に巻き付けられているとき前記隠蔽部は前記吸込パネル本体の前面の略全体を隠蔽することが望ましい。   Alternatively, the suction panel main body is formed in a substantially rectangular shape, and the covering portion is attached to a pair of take-up shafts attached along two opposite sides of the suction panel main body, and both ends are the pair. And a coating film extending along the front surface of the suction panel main body in a state of being wound around each winding shaft, and the coating film is formed to expose the front surface of the suction panel main body An exposed portion having an exposed hole, and a concealing portion formed to conceal the front surface of the suction panel main body, and the concealing portion is wound around one of the pair of winding shafts. The exposure hole exposes substantially the entire front surface of the suction panel body, and the concealing portion conceals substantially the entire front surface of the suction panel body when the exposed portion is wound around the other of the pair of winding shafts. To do Desirable.

本構成によれば、被覆膜の露出部を一対の巻取軸の他方に巻き付けることによって、一対の巻取軸の一方に巻き付けられていた被覆膜の隠蔽部が展張されて吸込パネル本体の前面を隠蔽するように吸込パネル本体の前面に沿って延在するようになる。したがって、吸込パネルを空調装置の空気吸込口前面から取り外す際に、簡単な作業で吸込パネル本体の前面を被覆膜の隠蔽部で覆い、吸込パネル本体の表面に堆積した埃が空調装置の下方の室内に落下することを簡単に防止できる。   According to this structure, the concealing portion of the coating film wound around one of the pair of winding shafts is expanded by winding the exposed portion of the coating film around the other of the pair of winding shafts, and the suction panel body It extends along the front surface of the suction panel body so as to conceal the front surface. Therefore, when removing the suction panel from the front surface of the air intake port of the air conditioner, the front surface of the suction panel body is covered with a concealing part of the coating film with a simple operation, and dust accumulated on the surface of the suction panel body is below the air conditioner. Can easily be prevented from falling into the room.

また、被覆膜の隠蔽部を一対の巻取軸の一方に再び巻き付けることによって、吸込パネルを空調装置の空気吸込口前面から取り外す際に一対の巻取軸の他方に巻き付けた被覆膜の露出部が再び展張されて吸込パネル本体の前面に沿って延在するようになり、露出部の露出孔から吸込パネル本体の前面が露出される。したがって、吸込パネル本体を空調装置の空気吸込口前面に再び取り付ける際に、簡単な作業で吸込パネル本体の前面を露出部の露出孔から露出させることができる。   In addition, by re-wrapping the concealing portion of the coating film around one of the pair of winding shafts, the coating film wound around the other of the pair of winding shafts when removing the suction panel from the front surface of the air suction port of the air conditioner.

And the coating film extends along the front surface of the suction panel so as to conceal substantially the entire front surface of the suction panel body when the tip shaft is at a position furthest away from the winding shaft. It is desirable to do.

本構成によれば、被覆膜の他端部が固定された先端軸を巻取軸から遠ざかるように吸込パネル本体の前面に沿って移動させることによって、巻取軸に巻き付けられていた被覆膜が展張されて吸込パネル本体の前面の略全体を隠蔽するように吸込パネル本体の前面に沿って延在するようになる。したがって、吸込パネルを空調装置の空気吸込口前面から取り外す際に、簡単な作業で吸込パネル本体の前面を被覆膜で覆い、吸込パネル本体の表面に堆積した埃が空調装置の下方の室内に落下することを簡単に防止できる。   According to this configuration, the coating wound around the take-up shaft by moving the tip shaft, to which the other end of the coating film is fixed, away from the take-up shaft along the front surface of the suction panel body. The membrane is extended to extend along the front surface of the suction panel body so as to hide substantially the entire front surface of the suction panel body. Therefore, when removing the suction panel from the front surface of the air inlet of the air conditioner, the front surface of the suction panel body is covered with a coating film by a simple operation, and dust accumulated on the surface of the suction panel body is placed in the room below the air conditioner. It can be easily prevented from falling.

また、被覆膜の他端部が固定された先端軸を巻取軸に近づけるように吸込パネル本体の前面に沿って移動させ、被覆膜を巻取軸に再び巻き付けることによって、被覆膜から吸込パネル本体の前面が再び露出される。したがって、吸込パネル本体を空調装置の空気吸込口前面に再び取り付ける際に、簡単な作業で吸込パネル本体の前面を被覆膜から露出させることができる。   Further, by moving the tip shaft, to which the other end portion of the coating film is fixed, along the front surface of the suction panel main body so as to be close to the winding shaft, the coating film is wound again on the winding shaft, thereby The front surface of the suction panel body is exposed again. Therefore, when the suction panel body is reattached to the front surface of the air suction port of the air conditioner, the front surface of the suction panel body can be exposed from the coating film with a simple operation.

At this time, the coating film 35 tends to be rewound onto the take-up shaft 33 by the restoring force of the spring built in the take-up shaft 33, but the protruding portion 39 or groove 39 ′ of the tip shaft 34 and the suction grill main body 31. The tip shaft 34 and the coating film 35 are not pulled back to the take-up shaft 33 side by the frictional force generated in the groove 38 or the protrusion 38 ′, and the cover film 35 is not between the take-up shaft 33 and the tip shaft 34. The extended state is maintained first. As a result, the coating film 35 wound around the take-up shaft 33 is extended and extends along the front surface of the suction grill body 31 so as to conceal substantially the entire front surface of the suction grill body 31. .

そして、この状態を保ちつつ吸込グリル３を空調装置の空気吸込口前面から取り外す。この状態で、吸込グリル３の裏側に取り付けられたエアフィルタを取り外して清掃あるいは交換を行う。   And the suction grill 3 is removed from the air suction inlet front surface of an air conditioner, maintaining this state. In this state, the air filter attached to the back side of the suction grill 3 is removed and cleaned or replaced.

エアフィルタの清掃、交換や空調装置のメンテナンス等の作業が終了したら、先端軸３４を巻取軸３３に近づけるように吸込グリル本体３１の前面に沿って移動させることによって、巻取軸３３に内蔵されたバネの復元力によって被覆膜３５が巻取軸３３に巻き付けられていき、被覆膜３５から吸込グリル本体３１の前面が再び露出される。そして、吸込グリル３を再び空調装置の空気吸込口前面に取り付ける。   When the operations such as cleaning and replacement of the air filter and maintenance of the air conditioner are completed, the tip shaft 34 is moved along the front surface of the suction grill body 31 so as to be close to the winding shaft 33, thereby being built in the winding shaft 33. The coating film 35 is wound around the take-up shaft 33 by the restoring force of the applied spring, and the front surface of the suction grill body 31 is exposed again from the coating film 35. Then, the suction grill 3 is attached again to the front surface of the air suction port of the air conditioner.

第３実施形態の吸込グリル３によれば、吸込グリル３上に支持されたエアフィルタの清掃や空調装置のメンテナンス等のために空調装置の空気吸込口前面から吸込グリル３を取り外す際に、埃が堆積した吸込グリル本体３１の前面を予め被覆膜３５で隠蔽するように覆った状態を保ちながら吸込グリル本体３１を空調装置の空気吸込口前面から取り外すことにより、吸込グリル本体３１の表面に堆積した埃が空調装置の下方の室内に落下することを簡単に防止できる。   According to the suction grill 3 of the third embodiment, when the suction grill 3 is removed from the front surface of the air suction port of the air conditioner for cleaning the air filter supported on the suction grill 3, maintenance of the air conditioner, or the like. By removing the suction grill body 31 from the front surface of the air intake port of the air conditioner while keeping the front surface of the suction grill body 31 on which the air is accumulated so as to be concealed by the coating film 35 on the surface of the suction grill body 31, It is possible to easily prevent the accumulated dust from falling into the room below the air conditioner.

具体的には、被覆膜３５の他端部３７が固定された先端軸３４を巻取軸３３から遠ざかるように吸込グリル本体３１の前面に沿って移動させることによって、巻取軸３３に巻き付けられていた被覆膜３５が吸込グリル本体３１の前面の略全体を隠蔽するように吸込グリル本体３１の前面に沿って延在するようになる。したがって、吸込グリル３１を空調装置の空気吸込口前面から取り外す際、簡単な作業で吸込グリル本体３１の前面を被覆膜で覆い、吸込グリル本体３１の表面に堆積した埃が空調装置の下方の室内に落下することを簡単に防止できる。   Specifically, the tip shaft 34 to which the other end portion 37 of the coating film 35 is fixed is moved around the front surface of the suction grill body 31 so as to move away from the winding shaft 33, whereby the winding shaft 33 is wound. The covered coating film 35 extends along the front surface of the suction grill body 31 so as to conceal substantially the entire front surface of the suction grill body 31. Therefore, when removing the suction grill 31 from the front surface of the air suction port of the air conditioner, the front surface of the suction grill body 31 is covered with a coating film by a simple operation, and dust accumulated on the surface of the suction grill body 31 is located below the air conditioner. It can be easily prevented from falling into the room.

また、被覆膜３５の他端部３７が固定された先端軸３４を巻取軸３３に近づけるように吸込グリル本体３１の前面に沿って移動させ、被覆膜３５を巻取軸３３に巻き付けることによって、被覆膜３５から吸込グリル本体３１の前面が露出される。したがって、吸込グリル本体３１を空調装置の空気吸込口前面に再び取り付ける際、簡単な作業で吸込グリル本体３１の前面を被覆膜から露出させることができる。   Further, the tip shaft 34 to which the other end portion 37 of the coating film 35 is fixed is moved along the front surface of the suction grill body 31 so as to approach the winding shaft 33, and the coating film 35 is wound around the winding shaft 33. As a result, the front surface of the suction grill body 31 is exposed from the coating film 35. Therefore, when the suction grill body 31 is reattached to the front surface of the air suction port of the air conditioner, the front surface of the suction grill body 31 can be exposed from the coating film with a simple operation.
