Description

本発明は、空気清浄機能を有する空気調和機に関する。 The present invention relates to an air conditioner having an air cleaning function.

近年、空気清浄機能を有するエアコン等の空気調和機が提案されている。空気清浄機能を有するエアコンの場合、吸込み側全面に空気清浄フィルタを配置する必要がある。しかしながら、家庭用の一般的なエアコンでは、送風装置としてクロスフローファンが用いられている。クロスフローファンでは静圧が低いため、吸込み側全面に空気清浄フィルタを配置することができず、また、吹出し側に熱交換器を配置することもできない。 In recent years, air conditioners such as air conditioners that have an air purifying function have been proposed. In the case of an air conditioner with an air purifying function, it is necessary to place an air purifying filter on the entire surface of the suction side. However, in general home air conditioners, a cross flow fan is used as a blower. Since the static pressure of a crossflow fan is low, an air purifying filter cannot be placed on the entire surface of the suction side, and a heat exchanger cannot be placed on the blowout side.

これに対して、例えば特許文献１に開示された天吊エアコンの場合、クロスフローファンよりも静圧が高いシロッコファンを利用している。このため、吸込み側全面に空気清浄フィルタを配置することが可能であり、また、吹出し側に熱交換器を配置することも可能である。 On the other hand, in the case of a ceiling-mounted air conditioner disclosed in Patent Document 1, for example, a sirocco fan having a higher static pressure than a cross flow fan is used. Therefore, it is possible to arrange an air purifying filter on the entire surface of the suction side, and it is also possible to arrange a heat exchanger on the outlet side.

〔実施形態１〕
以下、本発明の一実施形態について、詳細に説明する。 [Embodiment 1]
Hereinafter, one embodiment of the present invention will be described in detail.

（空気調和機１の構成）
図１は、本実施形態の空気調和機１の概略断面図である。図２は、図１に示す空気調和機１の上面側から見た斜視図である。 (Configuration of air conditioner 1)
FIG. 1 is a schematic cross-sectional view of an air conditioner 1 according to this embodiment. FIG. 2 is a perspective view of the air conditioner 1 shown in FIG. 1 viewed from the top side.

図１の符号１００１に示すように、空気調和機１は、筐体１１の内部における後部にシロッコファン４０を有し、前部に熱交換器１３を有している。ここで、筐体１１における前は、空気調和機１の設置面（室内の壁）と反対側とし、後は、空気調和機１の設置面側とする。 As shown by reference numeral 1001 in FIG. 1, the air conditioner 1 has a sirocco fan 40 at the rear inside the housing 11, and a heat exchanger 13 at the front. Here, the front side of the casing 11 is the opposite side to the installation surface (indoor wall) of the air conditioner 1, and the rear side is the installation surface side of the air conditioner 1.

筐体１１は、上面部に吸込み口２１を有し、前面部に開口部を有する。吸込み口２１には、フィルタユニット３１が設けられ、前面部の開口部には吹出し口２２が形成されている。フィルタユニット３１は、図２に示すように、空気調和機１の筐体１１の上面の２箇所の吸込み口２１それぞれを覆うように２個設けられている。 The housing 11 has a suction port 21 on the top surface and an opening on the front surface. A filter unit 31 is provided at the suction port 21, and an air outlet 22 is formed at the opening on the front surface. As shown in FIG. 2, two filter units 31 are provided so as to cover each of the two suction ports 21 on the upper surface of the housing 11 of the air conditioner 1.

シロッコファン４０は、空気を円筒形の軸方向から吸い込み、半径方向の外側へ吹き出す送風ファン１２と、当該送風ファン１２を熱交換器１３側の領域を除いて覆うケーシング２３とを含んでいる。ケーシング２３は、送風ファン１２の回転軸方向（筐体１１の長手方向）に延びる渦巻き形状をしている。具体的には、上側に位置する前端部が熱交換器１３の上端部の位置に達し、この位置から後方へ向かって延び、送風ファン１２の上方位置、送風ファン１２の後方位置、送風ファン１２の下方位置を経て、熱交換器１３の後面に達している。シロッコファン４０の舌部４１（厳密にはケーシング２３における渦巻き形状の始点となる舌部４１）は、熱交換器１３の後面に近接して配置されることになる。舌部４１の配置位置についての詳細は後述する。 The sirocco fan 40 includes a blower fan 12 that sucks air from the axial direction of a cylinder and blows it outward in the radial direction, and a casing 23 that covers the blower fan 12 except for the area on the heat exchanger 13 side. The casing 23 has a spiral shape extending in the direction of the rotation axis of the blower fan 12 (the longitudinal direction of the housing 11). Specifically, the front end located on the upper side reaches the position of the upper end of the heat exchanger 13 and extends rearward from this position, and the upper position of the ventilation fan 12 , the rear position of the ventilation fan 12 , the ventilation fan 12 It reaches the rear surface of the heat exchanger 13 through the lower position of. The tongue portion 41 of the sirocco fan 40 (strictly speaking, the tongue portion 41 that is the starting point of the spiral shape in the casing 23) is arranged close to the rear surface of the heat exchanger 13. Details regarding the arrangement position of the tongue portion 41 will be described later.

熱交換器１３は、上部が下部よりも前方位置となる傾斜状態に配置され、下部は送風ファン１２と近接した状態に配置されている。熱交換器１３は、傾斜状態に配置されることにより、鉛直状態に配置される場合と比較して、空気調和機１の高さを抑制しながら表面積を広くできるようにしている。なお、熱交換器１３の傾斜状態は、上記の状態に限定されず、下部が上部よりも前方位置となる傾斜状態に配置されていてもよい。この場合にも、熱交換器１３は、鉛直状態に配置される場合と比較して、空気調和機１の高さを抑制しながら表面積を広くすることができる。 The heat exchanger 13 is arranged in an inclined state in which the upper part is in a forward position than the lower part, and the lower part is arranged in a state close to the blower fan 12. By arranging the heat exchanger 13 in an inclined state, it is possible to increase the surface area while suppressing the height of the air conditioner 1 compared to a case in which the heat exchanger 13 is arranged in a vertical state. Note that the inclined state of the heat exchanger 13 is not limited to the above-mentioned state, and may be arranged in an inclined state in which the lower part is located in front of the upper part. Also in this case, the heat exchanger 13 can increase the surface area while suppressing the height of the air conditioner 1 compared to the case where it is arranged vertically.

空気調和機１は、前面部に吹出し口２２を開閉する前面パネル２４を備えている。前面パネル２４は、図１の符号１００１に示すように、上縁部と下縁部との間が緩やかに湾曲した板形状に形成されている。前面パネル２４の湾曲の方向は、正面から見て凹状となる方向である。 The air conditioner 1 includes a front panel 24 that opens and closes the air outlet 22 on the front surface. The front panel 24, as shown by reference numeral 1001 in FIG. 1, is formed into a plate shape that is gently curved between an upper edge and a lower edge. The direction of curvature of the front panel 24 is the direction in which it becomes concave when viewed from the front.

前面パネル２４は、例えば前面パネル２４を支持する左右２個所のアームおよびモータを有する従来周知の駆動機構（図示せず）により駆動される。前面パネル２４は、図１の符号１００１に示すように、空気調和機１の停止時には吹出し口２２を閉じた状態となり、運転時には開いた状態となる。 The front panel 24 is driven by a conventionally known drive mechanism (not shown) having, for example, two left and right arms supporting the front panel 24 and a motor. As shown by reference numeral 1001 in FIG. 1, the front panel 24 has the outlet 22 closed when the air conditioner 1 is stopped, and is open when the air conditioner 1 is in operation.

フィルタユニット３１は、空気清浄効果の高いフィルタ、例えばＨＥＰＡフィルタ(High Efficiency Particulate Air Filter)等のフィルタとしての空気清浄フィルタ２６と、空気清浄フィルタ２６を収容して保持する枠部２７とを含んでいる。 The filter unit 31 includes an air purifying filter 26 as a filter with a high air purifying effect, such as a HEPA filter (High Efficiency Particulate Air Filter), and a frame portion 27 that accommodates and holds the air purifying filter 26. There is.

（シロッコファン４０の舌部４１の配置位置）
シロッコファン４０の舌部４１は、図１の符号１００２に示すように、熱交換器１３の後面１３ｂと、前記空気清浄フィルタ２６の下面２６ｂと、熱交換器１３の下部側の端面１３ａと空気清浄フィルタ２６の後端側の端面２６ａとを結んで得られる面４２とで囲まれた空間に配置されている。 (Arrangement position of tongue portion 41 of sirocco fan 40)
As shown by reference numeral 1002 in FIG. 1, the tongue portion 41 of the sirocco fan 40 is connected to the rear surface 13b of the heat exchanger 13, the lower surface 26b of the air purifying filter 26, the lower end surface 13a of the heat exchanger 13, and the air. It is arranged in a space surrounded by a surface 42 obtained by connecting the end surface 26a of the cleaning filter 26 on the rear end side.

このように、舌部４１が配置されていることで、熱交換器１３と送風ファン１２とを近接して設けることが可能となり、空気調和機１の寸法を小さくすることが可能となる。具体的には、家庭用の壁付け室内機の寸法に収めることが可能となる。 By arranging the tongue portion 41 in this way, it becomes possible to provide the heat exchanger 13 and the blower fan 12 close to each other, and it becomes possible to reduce the size of the air conditioner 1. Specifically, it becomes possible to fit it into the dimensions of a wall-mounted indoor unit for home use.

シロッコファンの回転中心、すなわち送風ファン１２の回転中心１２ａは、図１の符号１００２に示すように、熱交換器１３の風を受ける面（後面１３ｂ）から伸びる垂直線上に設定されていることが好ましい。 The rotation center of the sirocco fan, that is, the rotation center 12a of the blower fan 12, is set on a vertical line extending from the wind receiving surface (rear surface 13b) of the heat exchanger 13, as shown by reference numeral 1002 in FIG. preferable.

この場合、熱交換器１３の風を受ける面（後面１３ｂ）に送風ファン１２をさらに近づけることが可能となる。これにより、送風ファン１２から吹き出す風を効率よく熱交換器１３に吹き付けることが可能となるので、熱交換効率もよくなる。 In this case, the blower fan 12 can be brought closer to the wind-receiving surface (rear surface 13b) of the heat exchanger 13. This makes it possible to efficiently blow the air blown from the blower fan 12 onto the heat exchanger 13, thereby improving the heat exchange efficiency.

特に、熱交換器１３の下部側の端面１３ａと空気清浄フィルタ２６の後端側の端面２６ａとを結んで得られる面４２が、前記シロッコファンの回転中心を通る位置から、当該回転中心よりも前方の所定位置までの位置を通ることが好ましい。ここで、前方の所定位置とは、ケーシング２３の舌部４１の位置吹出し口が空気調和機１３の後面１３ｂからはみ出さない位置（舌部４１の形成位置が好ましい）とする。 In particular, the surface 42 obtained by connecting the end surface 13a on the lower side of the heat exchanger 13 and the end surface 26a on the rear end side of the air purifying filter 26 extends from a position passing through the rotation center of the sirocco fan to a position further than the rotation center. It is preferable to pass through a position up to a predetermined position in front. Here, the predetermined position at the front is defined as a position where the tongue part 41 of the casing 23 does not protrude from the rear surface 13b of the air conditioner 13 (the position where the tongue part 41 is formed is preferable).

この場合、送風ファン１２の吹出し口を熱交換器１３における風を受ける面により近づけることが可能となる。これにより、送風ファン１２から吹き出す風をより効率よく熱交換器１３に吹き付けることが可能となるので、熱交換効率がさらによくなる。 In this case, the outlet of the blower fan 12 can be brought closer to the surface of the heat exchanger 13 that receives the wind. This makes it possible to more efficiently blow the air blown from the blower fan 12 onto the heat exchanger 13, thereby further improving the heat exchange efficiency.

（ケーシング２３の詳細）
図３は、図１に示す空気調和機１のシロッコファン４０のケーシング２３の概略斜視図である。図４は、図３に示すケーシング２３の下半分を分割して取り外す状態を説明するための概略斜視図である。図５は、図３に示すケーシング２３の下半分を分割して取り外す状態を説明するための概略斜視図である。図６は、図１に示す空気調和機１のメンテナンス開口部と、ケーシング２３の外径との関係を説明するための概略断面図である。 (Details of casing 23)
FIG. 3 is a schematic perspective view of the casing 23 of the sirocco fan 40 of the air conditioner 1 shown in FIG. FIG. 4 is a schematic perspective view for explaining a state in which the lower half of the casing 23 shown in FIG. 3 is divided and removed. FIG. 5 is a schematic perspective view for explaining a state in which the lower half of the casing 23 shown in FIG. 3 is divided and removed. FIG. 6 is a schematic cross-sectional view for explaining the relationship between the maintenance opening of the air conditioner 1 shown in FIG. 1 and the outer diameter of the casing 23.

シロッコファン４０のケーシング２３は、図３に示すように、上ケーシング部２３ａと下ケーシング部２３ｂとに分離可能に上下に分割され、さらに、下ケーシング部２３ｂは、２つの部材２３ｂ１・２３ｂ２に分離可能に分割されている。 As shown in FIG. 3, the casing 23 of the sirocco fan 40 is separably divided vertically into an upper casing part 23a and a lower casing part 23b, and the lower casing part 23b is further separated into two members 23b1 and 23b2. possible to be divided.

このように、ケーシング２３の下ケーシング部２３ｂを少なくとも２つの部材２３ｂ１・２３ｂ２に分離可能に分割することで、当該下ケーシング部２３ｂは以下のように取り外すことになる。下ケーシング部２３ｂを筐体１１から取り出す際に、図４に示すように、下ケーシング部２３ｂの部材２３ｂ１を取り外し、その後、図５に示すように、舌部４１側の部材２３ｂ２を取り外すことになる。 By thus separably dividing the lower casing part 23b of the casing 23 into at least two members 23b1 and 23b2, the lower casing part 23b can be removed as follows. When taking out the lower casing part 23b from the housing 11, as shown in FIG. 4, the member 23b1 of the lower casing part 23b is removed, and then, as shown in FIG. 5, the member 23b2 on the tongue part 41 side is removed. Become.

これにより、図６に示すように、筐体１１の下部（空気清浄フィルタ２６の設置面と反対側の面）のメンテナンス用の開口１１ａの前後方向の長さＸが、ケーシング２３の前後方向の最大径Ｙよりも小さくても、下ケーシング部２３ｂを分割して取り出せる。従って、シロッコファン４０に近接して熱交換器１３が配置されていても、当該熱交換器１３が邪魔することなく、下ケーシング部２３ｂを筐体１１内から取り出すことが可能となる。 As a result, as shown in FIG. Even if the diameter is smaller than the maximum diameter Y, the lower casing part 23b can be divided and taken out. Therefore, even if the heat exchanger 13 is disposed close to the sirocco fan 40, the lower casing portion 23b can be taken out from the housing 11 without being obstructed by the heat exchanger 13.

なお、筐体１１下部のメンテナンス用の開口１１ａのサイズは、下ケーシング部２３ｂの分割された部材２３ｂ１・２３ｂ２を外部に取り出し可能な大きさに設定されていることが好ましい。 Note that the size of the maintenance opening 11a at the bottom of the housing 11 is preferably set to a size that allows the divided members 23b1 and 23b2 of the lower casing portion 23b to be taken out to the outside.

また、本実施形態では、下ケーシング部２３ｂを２つの部材に分割した例について説明したが、これに限定されるものでなく、３つ以上の部材に分割してもよい。 Further, in this embodiment, an example in which the lower casing portion 23b is divided into two members has been described, but the present invention is not limited to this, and the lower casing portion 23b may be divided into three or more members.
