Description

本発明は、ルームエアコンなどの空気調和装置に関し、特に、その換気に関する。   The present invention relates to an air conditioner such as a room air conditioner, and more particularly to ventilation thereof.

従来、空気調和装置は一般的には、換気機能を有しておらず、室内の空気が汚れた際などには適宜、人が窓を開けるなどして、外気を取り入れて換気する必要があった。   Conventionally, an air conditioner generally does not have a ventilation function, and when indoor air becomes dirty, it is necessary for a person to open the window as appropriate to ventilate outside air. It was.

そこで、従来より、空気調和装置に換気装置を設けたものが提案されている。たとえば特許文献1に記載されているように、給気ダクトと排気ダクトとを設け、この給気ダクトに給気用送風機を、また、排気ダクトに排気用送風機を設けた空気調和装置がある。
特開2001−304645号公報
Therefore, conventionally, an air conditioner provided with a ventilation device has been proposed. For example, as disclosed in Patent Document 1, there is an air conditioner in which an air supply duct and an exhaust duct are provided, an air supply fan is provided in the air supply duct, and an air exhaust fan is provided in the exhaust duct.
JP 2001-304645 A

ところで、この従来の特許文献1に記載されている空気調和装置は、事務所ビルなどに設置されるもので、給気ダクトと排気ダクトとは各々、別の建屋の孔に挿入されている。そのため、給気ダクト用の孔と排気ダクト用の孔との2個を設ける必要があり、工数が増大するとともに、見栄えが悪くなる。   By the way, this conventional air conditioner described in Patent Document 1 is installed in an office building or the like, and an air supply duct and an exhaust duct are respectively inserted into holes of different buildings. Therefore, it is necessary to provide two holes for the air supply duct and the hole for the exhaust duct, which increases the number of steps and deteriorates the appearance.

また、ルームエアコンなどの空気調和装置では、一本の通風ホースで換気するものが従来提案されている。この場合には、排気または給気の一方のみを行うことができ、同時に排気および給気の両方を行うことができない。そこで、2本の通風ホースを備えて、排気および給気の両方を同時に行うことができる空気調和装置を検討した。しかしながら、この2本の通風ホースを束ねて建屋の同じ孔に挿入して外に出して、排気用の通風ホースの先端と、給気用の通風ホースの先端とを並べて設置すると、排気用の通風ホースにより排気された室内からの汚れた空気が、そのまま、給気用の通風ホースにより吸い込まれ、室内に戻ってしまうエアーショートの状態を引き起こしてしまう。   In addition, as an air conditioner such as a room air conditioner, one that has been ventilated with a single ventilation hose has been proposed. In this case, only one of exhaust and air supply can be performed, and both exhaust and air supply cannot be performed at the same time. In view of this, an air conditioner that includes two ventilation hoses and can perform both exhaust and air supply at the same time was studied. However, if these two ventilation hoses are bundled and inserted into the same hole in the building and are taken out, the exhaust ventilation hose and the air supply ventilation hose are arranged side by side to install the exhaust ventilation hose. The dirty air from the room exhausted by the ventilation hose is sucked in by the ventilation hose for supplying air as it is, and causes an air short state that returns to the room.

解決しようとする問題点は、排気用の通風ホースと給気用の通風ホースとを束ねて同じ孔に挿入して外に出して、両通風ホースの先端を並べて設置すると、室内から排気された汚れた空気が、そのまま吸い込まれ、室内に戻ってしまうエアーショートの状態を引き起こしてしまう点である。   The problem to be solved is that when the ventilation hose for exhaust and the ventilation hose for air supply are bundled and inserted into the same hole and put out, the tips of both ventilation hoses are placed side by side and exhausted from the room Dirty air is sucked in as it is and causes an air short state that returns to the room.

本発明の空気調和装置は、室内機(1)からの冷媒配管(2)が、建屋の孔(4)を通って屋外に導き出されて、室外機(3)に接続されている。そして、室内機内に配置されるとともに、外気を吸い込んで室内に給気する給気機能を具備する第1送風装置(21)と、室内機内に配置されるとともに、室内の空気を吸い込んで室外に排気する排気機能を具備する第2送風装置(22)と、第1送風装置に接続されるとともに、建屋の孔に挿入されて先端部が前記孔から外に延在している第1通風ホース(23)と、第2送風装置に接続されるとともに、第1通風ホースと束ねられ、第1通風ホースとともに建屋の前記孔に挿入されて先端部が前記孔から外に延在している第2通風ホース(24)とを備えているIn the air conditioner of the present invention, the refrigerant pipe (2) from the indoor unit (1) is led to the outside through the hole (4) of the building and connected to the outdoor unit (3). And while being arrange | positioned in an indoor unit, the 1st air blower (21) which comprises the air supply function which suck | inhales external air and supplies air indoors, It is arrange | positioned in an indoor unit and sucks indoor air outside. A second blower (22) having an exhaust function for exhausting, and a first ventilation hose that is connected to the first blower and is inserted into a hole in the building and has a distal end extending outward from the hole. (23) is connected to the second blower and is bundled with the first ventilation hose, and inserted into the hole of the building together with the first ventilation hose, and the tip portion extends outward from the hole. and a 2 ventilation hose (24).

そして、建屋の孔を覆うとともに下面開口を具備する孔カバー(41)が設けられ、この孔カバー内には多数の孔を具備する仕切り(42)が設けられ、第1通風ホースの先端は仕切りよりも内側に配置され、第2通風ホースの先端は孔カバーの下面開口から下方に垂れ下がっており、第1通風ホースの端部開口と第2通風ホースの端部開口との距離が70mm以上ある And the hole cover (41) which covers the hole of a building and has a lower surface opening is provided, and the partition (42) which has many holes is provided in this hole cover, and the front-end | tip of a 1st ventilation hose is a partition. The tip of the second ventilation hose hangs downward from the lower surface opening of the hole cover, and the distance between the end opening of the first ventilation hose and the end opening of the second ventilation hose is 70 mm or more. .

また、第1通風ホースおよび第2通風ホースの先端には各々、通風ホース本体の外径よりも大きな外径を有する虫除けカバー(31,32)が設けられていることがある。 Moreover , the insect repellent cover (31, 32) which has an outer diameter larger than the outer diameter of a ventilation hose main body may be provided in the front-end | tip of a 1st ventilation hose and a 2nd ventilation hose, respectively.

本発明によれば、第1通風ホースと第2通風ホースとは束ねられて、建屋の孔に挿入されて先端部が外に延在するとともに、第1通風ホースの端部開口と第2通風ホースの端部開口との距離が70mm以上あるので、通風ホース用の孔は1個形成すればよく、見栄えが良好となるとともに、エアーショートを極力防止することができる。   According to the present invention, the first ventilation hose and the second ventilation hose are bundled and inserted into the hole of the building so that the tip portion extends outside, and the end opening of the first ventilation hose and the second ventilation hose are extended. Since the distance from the end opening of the hose is 70 mm or more, it is sufficient to form one hole for the ventilation hose, the appearance is good, and an air short circuit can be prevented as much as possible.

また、建屋の孔を覆うとともに下面開口を具備する孔カバーが設けられ、この孔カバー内には多数の孔を具備する仕切りが設けられ、第1通風ホースの先端は仕切りよりも内側に配置され、第2通風ホースの先端は孔カバーの下面開口から下方に垂れ下がっているので、虫、ゴミや雨水などが給気側の第1通風ホース内に侵入することを極力防止することができる。   In addition, a hole cover that covers the hole of the building and has an opening on the lower surface is provided, a partition having a large number of holes is provided in the hole cover, and a tip of the first ventilation hose is disposed on the inner side of the partition. Since the tip of the second ventilation hose hangs downward from the opening on the lower surface of the hole cover, it is possible to prevent insects, dust, rainwater, etc. from entering the first ventilation hose on the supply side as much as possible.

排気用の通風ホースと給気用の通風ホースとを束ねて同じ孔に挿入して外に出して給排気を行っても、室内から排気された汚れた空気がそのまま吸い込まれ室内に戻ってしまうエアーショートの状態を防止するという目的を、第1通風ホースの端部開口と第2通風ホースの端部開口との距離を70mm以上にすることで実現した。   Even if the ventilation hose for exhaust and the ventilation hose for air supply are bundled and inserted into the same hole and out, the dirty air exhausted from the room is sucked in and returned to the room The object of preventing an air short-circuit state was realized by setting the distance between the end opening of the first ventilation hose and the end opening of the second ventilation hose to 70 mm or more.

次に、本発明における空気調和装置の第1実施例について、図1ないし図4を用いて説明する。図1は本発明における第1実施例の空気調和装置の室内機および室外機の斜視図である。図2は室内機の要部の一部切欠き斜視図である。図3は冷媒配管や通風ホースなどを建屋の孔から外に取り出した組み立て途中の状態の斜視図である。図4は建屋の孔から外に取り出された冷媒配管や通風ホースなどを化粧テープで固定した設置完了の状態の斜視図である。   Next, a first embodiment of an air conditioner according to the present invention will be described with reference to FIGS.

FIG. 2 is a partially cutaway perspective view of a main part of the indoor unit. FIG. 3 is a perspective view of a state in the middle of assembly in which refrigerant pipes, ventilation hoses and the like are taken out from holes in the building. FIG. 4 is a perspective view showing a state where the installation is completed by fixing the refrigerant pipe, the ventilation hose and the like taken out from the hole of the building with a decorative tape.

まず始めに、空気調和装置の全体構成を説明する。
図1において、空気調和装置は、室内機1および、この室内機1と冷媒配管2で接続される室外機3を備えている。室内機1は屋内に設置され、一方、室外機3は屋外に設置されており、冷媒配管2は冷媒細管2a(図3参照)と冷媒太管2b(図3参照)の2本で構成されるとともに、建屋に形成された孔4を通って、室内機1と室外機3とを接続している。また、室外機3は、図示はしていないが従来の空気調和装置と同様にして、冷媒を圧縮する圧縮機、室外機用熱交換器、冷媒の循環流路を切り換える冷媒流路切換弁および熱交換器用送風機などの機器を具備している。そして、室外機3の運転時には、冷凍サイクルの冷媒が室外機3から暖冷房のために冷媒配管2を介して室内機1に循環している。
First, the overall configuration of the air conditioner will be described.
In FIG. 1, the air conditioner includes an indoor unit 1 and an outdoor unit 3 connected to the indoor unit 1 through a refrigerant pipe 2. The indoor unit 1 is installed indoors, while the outdoor unit 3 is installed outdoors, and the refrigerant pipe 2 is composed of two refrigerant tubes 2a (see FIG. 3) and a refrigerant thick tube 2b (see FIG. 3). In addition, the indoor unit 1 and the outdoor unit 3 are connected through a hole 4 formed in the building. Although not shown, the outdoor unit 3 includes a compressor that compresses the refrigerant, a heat exchanger for the outdoor unit, a refrigerant flow path switching valve that switches the refrigerant circulation flow path, Equipment such as a heat exchanger blower is provided. During operation of the outdoor unit 3, the refrigerant in the refrigeration cycle circulates from the outdoor unit 3 to the indoor unit 1 via the refrigerant pipe 2 for heating and cooling.

室内機1は、従来の空気調和装置と同様にして、室内機用熱交換器6(図2参照)および、室内機用熱交換器6で熱交換された空気を室内に送風するための循環用送風機(図示しない)を具備している。また、室内機1の前面には、可動な前面パネル8が設けられ、この前面パネル8の後側に、空気吸込口(図示しない)が設けられている。室内機1の稼働中は、前面パネル8は前側に移動して、空気吸込口から室内の空気を室内機1内に取り込むことが可能となる。また、室内機1の停止時には、前面パネル8は後側すなわち空気吸込口側に移動して見栄えを良好にしている。室内機1の下側には、空気吹出口12が設けられている。そして、室内機用熱交換器6の上側には、紫外線ランプ装置14(図2参照)が配置されている。   The indoor unit 1 is circulated for blowing indoor air into the indoor unit heat exchanger 6 (see FIG. 2) and the indoor unit heat exchanger 6 in the same manner as a conventional air conditioner. A blower (not shown) is provided. A movable front panel 8 is provided on the front surface of the indoor unit 1, and an air inlet (not shown) is provided on the rear side of the front panel 8. While the indoor unit 1 is in operation, the front panel 8 moves to the front side, and indoor air can be taken into the indoor unit 1 from the air suction port. Further, when the indoor unit 1 is stopped, the front panel 8 moves to the rear side, that is, the air suction port side, to improve the appearance. An air outlet 12 is provided below the indoor unit 1. And the ultraviolet lamp device 14 (refer FIG. 2) is arrange | positioned above the heat exchanger 6 for indoor units.

そして、室内機1の循環用送風機が稼働すると、室内の空気が、空気吸込口から吸い込まれ、フィルタで濾過された後に、室内機用熱交換器6で熱交換され、空気吹出口12から室内に吹き出している。この様にして、循環用送風機で室内の空気を循環させながら、この空気を室内機用熱交換器6で熱交換している。   Then, when the circulation blower of the indoor unit 1 is operated, the indoor air is sucked from the air suction port, filtered by the filter, and then heat-exchanged by the indoor unit heat exchanger 6, and the indoor air is discharged from the air outlet 12 to the room. Is blowing out. In this manner, while the indoor air is circulated by the circulation fan, this air is heat-exchanged by the indoor unit heat exchanger 6.

図2において、室内機1内の端部には、従来の空気調和装置とは異なり、給排両用送風装置である第1送風装置21および、排気用送風装置である第2送風装置22が設けられている。各送風装置21,22には、可撓性の通風ホース23,24が接続され、この通風ホース23,24が冷媒配管2、ドレーンホース26やユニット間ケーブル27と共に、テープなどの結束具で束ねられて、建屋に形成された孔4を通って、屋外に導かれている。第1通風ホース23の先端には、逆止弁を具備しない虫除けカバー31が設けられ、また、第2通風ホース24の先端には、逆止弁を具備する虫除けカバー32が設けられている。虫除けカバー32の逆止弁は、空気の流れの逆流を防止する。そして、虫除けカバー31,32の外径は、通風ホース23,24の本体の外径よりも大きく形成されている。また、図4に図示するように、通風ホース23,24などが挿入された後の孔4の隙間は、パテ36で埋められるとともに、孔4から外に延在している通風ホース23,24、冷媒配管2、ドレーンホース26やユニット間ケーブル27は、化粧テープ38でテーピングされ結束される。この際に、通風ホース23,24は、その先端開口が下向きになるように配置されるとともに、先端の虫除けカバー31,32は露出される。   In FIG. 2, unlike the conventional air conditioning apparatus, the 1st air blower 21 which is a supply / exhaust air blower, and the 2nd air blower 22 which is an exhaust air blower are provided in the edge part in the indoor unit 1. It has been. Flexible ventilation hoses 23 and 24 are connected to each of the air blowers 21 and 22, and the ventilation hoses 23 and 24 are bundled together with a refrigerant pipe 2, a drain hose 26 and an inter-unit cable 27 with a binding tool such as a tape. And led to the outside through the hole 4 formed in the building. An insect repellent cover 31 that does not include a check valve is provided at the tip of the first ventilation hose 23, and an insect repellent cover 32 that includes a check valve is provided at the tip of the second ventilation hose 24. The check valve of the insect repellent cover 32 prevents the backflow of the air flow. The outer diameters of the insect repellent covers 31 and 32 are formed larger than the outer diameters of the main bodies of the ventilation hoses 23 and 24. Further, as shown in FIG. 4, the gap of the hole 4 after the ventilation hoses 23 and 24 are inserted is filled with the putty 36 and the ventilation hoses 23 and 24 extending outward from the hole 4. The refrigerant pipe 2, the drain hose 26 and the inter-unit cable 27 are taped and bound by a decorative tape 38. At this time, the ventilation hoses 23 and 24 are arranged so that the opening of the tip is directed downward, and the insect repellent covers 31 and 32 at the tip are exposed.

この実施例の空気調和装置の換気の運転モードには、第1送風装置21が給気運転する単独給気モード、第2送風装置22が排気運転する単独排気モード、第1送風装置21が給気運転するとともに第2送風装置22が排気運転する給排気モード、並びに、第1送風装置21および第2送風装置22の両者が排気運転するダブル排気モードの4個のモードがある。   In the ventilation operation mode of the air conditioner of this embodiment, the single air supply mode in which the first air blower 21 performs the air supply operation, the single exhaust mode in which the second air blower 22 performs the exhaust operation, and the first air blower 21 is supplied. There are four modes: an air supply / exhaust mode in which the second blower 22 performs an exhaust operation and a double exhaust mode in which both the first blower 21 and the second blower 22 perform an exhaust operation.

そして、給排気モードの際に、通風ホース23,24の端部が並んで配置されていると、前述のようにエアーショートの状態を引き起こすため、実施例では、第1通風ホース23の孔4から外に延在している長さが、第2通風ホース24の孔4から外に延在している長さよりもΔL(図4参照)だけ短くなっている。すなわち、第1通風ホース23の端部開口(虫除けカバー31の下面)と第2通風ホース24の端部開口(虫除けカバー32の下面)との距離が、ΔLとなっている。   In the air supply / exhaust mode, if the end portions of the ventilation hoses 23 and 24 are arranged side by side, an air short state is caused as described above. Therefore, in the embodiment, the hole 4 of the first ventilation hose 23 is used. The length extending outside from the second ventilation hose 24 is shorter than the length extending outside from the hole 4 of the second ventilation hose 24 by ΔL (see FIG. 4). That is, the distance between the end opening of the first ventilation hose 23 (the lower surface of the insect repellent cover 31) and the end opening of the second ventilation hose 24 (the lower surface of the insect repellent cover 32) is ΔL.

この距離ΔLは、タバコの粉塵による試験等により、少なくとも70mmあれば、第2通風ホース24から排気された空気が、第1通風ホース23に殆ど吸い込まれることがないことを確認した。また、距離ΔLを300mm以上にすると、一方の通風ホースを他方の通風ホースよりも約300mm以上長くする必要が生じるため、通風ホースや化粧テープ38などの材料コストが上昇する。したがって、距離ΔLは70〜300mmの範囲にすることが好ましい。特に、約100mmにすることが好ましい。   When the distance ΔL is at least 70 mm by a test with tobacco dust or the like, it was confirmed that the air exhausted from the second ventilation hose 24 is hardly sucked into the first ventilation hose 23. Further, when the distance ΔL is set to 300 mm or more, it is necessary to make one ventilation hose longer than the other ventilation hose by about 300 mm or more, and thus the material cost of the ventilation hose and the decorative tape 38 increases. Therefore, the distance ΔL is preferably in the range of 70 to 300 mm. In particular, the thickness is preferably about 100 mm.

次に、本発明における空気調和装置の第2実施例について説明する。図5は建屋の孔をカバーする孔カバーの第1カバー体の説明図で、(a)が網部の一部を切り取る作業時の斜視図、(b)が網部の一部を切除した後の要部斜視図である。図6は孔カバーの基部が建屋の孔に取り付けられた状態の斜視図である。図7は孔カバーの基部に第1カバー体を取り付ける作業時の斜視図である。図8は孔カバーが組み立てられた状態の斜視図である。図9は図8の概略の断面図である。なお、この第2実施例の説明において、前記第1実施例の構成要素に対応する構成要素には同一符号を付して、その詳細な説明は省略する。   Next, a second embodiment of the air conditioner according to the present invention will be described.

As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various change is performed within the range of the summary of this invention described in the claim. It is possible. Examples of modifications of the present invention are illustrated below.
(1) As long as the first blower 21 has at least an air supply function and the second blower 22 has at least an exhaust function, the types and structures of the blowers 21 and 22 are appropriately determined. Selectable. For example, the first air blower 21 can be a dedicated air blower, and the second air blower 22 can be a blower capable of supplying and exhausting air.

(2)冷媒配管2と通風ホース23,24は、建屋の同じ孔に挿入されることも可能であるし、また、各々別の孔に挿入されることも可能である。ただし、通風ホース23,24は同じ孔に挿入される。 (2) The refrigerant pipe 2 and the ventilation hoses 23 and 24 can be inserted into the same hole of the building, or can be inserted into different holes, respectively. However, the ventilation hoses 23 and 24 are inserted in the same hole.

)第1通風ホース23の端部開口と、第2通風ホース24の端部開口との距離ΔLは、エアーショートを生じさせない値に設定されるが、70mm以上あれば、エアーショートを防止することができる。そして、第1通風ホース23と第2通風ホース24とは結束して束ねられているため、孔4から外側に延在する通風ホースの長さは、第1通風ホース23の長さと第2通風ホース24の長さとの差が、端部開口間の距離ΔLと略同じ値となるようにすることが好ましい。
)第1通風ホース23および第2通風ホース24は束ねられているが、結束箇所は、部分的でも、または、全体的でも可能である。
( 3 ) The distance ΔL between the end opening of the first ventilation hose 23 and the end opening of the second ventilation hose 24 is set to a value that does not cause an air short, but if it is 70 mm or more, the air short is prevented. can do. Since the first ventilation hose 23 and the second ventilation hose 24 are bundled and bundled, the length of the ventilation hose extending outward from the hole 4 is equal to the length of the first ventilation hose 23 and the second ventilation hose. It is preferable that the difference from the length of the hose 24 is approximately the same as the distance ΔL between the end openings.
( 4 ) Although the 1st ventilation hose 23 and the 2nd ventilation hose 24 are bundled, the binding location may be partial or whole.

第1通風ホースと第2通風ホースとを束ねて、建屋の孔に挿入し先端部を外に延在させるとともに、第1通風ホースの端部開口と第2通風ホースの端部開口との距離を70mm以上にすることにより、エアーショートの状態を防止しながら、給排気を行うことができる。そのため、空気調和とともに換気(特に給排気)を行う空気調和装置に適用することが最適である。   The first ventilation hose and the second ventilation hose are bundled and inserted into a hole in the building to extend the tip portion outward, and the distance between the end opening of the first ventilation hose and the end opening of the second ventilation hose By setting the length to 70 mm or more, air supply and exhaust can be performed while preventing an air short-circuit state. Therefore, it is optimal to apply it to an air conditioner that performs ventilation (particularly air supply / exhaust) together with air conditioning.
