Abstract

The present invention makes it possible to prevent the occurrence of a phenomenon in which an intake port on an underside surface does not function in some cases due to differing environmental conditions. A casing (11) has a top-surface intake port (21) and an underside-surface intake port (22). An indoor fan (15) creates a flow of air taken in from each intake port (21, 22). An indoor heat exchanger (13) forms a substantially reverse-V-like shape from front-side heat-exchanger units (13a, 13b) and a rear-side heat-exchanger unit (13c). An intake-resistance unit (50) is intended to obstruct the flow of air taken in from the top-surface intake port (21). Specifically, the indoor fan (15) creates a flow of air within the room, the air being taken in from the intake ports (21, 22) and flowing into the rear-side heat-exchanger unit (13c). The intake-resistance unit (50) is positioned in the top-surface intake port (21) corresponding to the rear-side heat-exchanger unit (13c).

Description

空調室内機Air conditioning indoor unit
　本発明は、空調室内機、特に、壁掛タイプの空調室内機に関する。 The present invention relates to an air conditioning indoor unit, and more particularly to a wall-hanging type air conditioning indoor unit.
　空調機には、屋外に設置される室外機と室内に設置される室内機とで構成されるセパレートタイプのものがある。特に、室内機には、室内の壁面等に取り付けられる壁掛タイプのものがある。
　壁掛タイプの室内機としては、例えば特許文献１（特開２００１－３１１５３０号公報）に示されるものが知られている。特許文献１に係る室内機は、天面に天面吸込口を有し、下面に下面吸込口と吹出口とを有している。この室内機によると、室内空気は、両吸込口から吸い込まれ熱交換器にて熱交換された後、吹出口を介して室内へと吹き出される。 There is a separate type of air conditioner composed of an outdoor unit installed outdoors and an indoor unit installed indoors. In particular, the indoor unit includes a wall-hanging type that is attached to an indoor wall surface or the like.
As a wall-hanging type indoor unit, for example, the one shown in Patent Document 1 (Japanese Patent Laid-Open No. 2001-311530) is known. The indoor unit according to Patent Document 1 has a top surface suction port on the top surface, and has a bottom surface suction port and an air outlet on the bottom surface. According to this indoor unit, the indoor air is sucked from both the suction ports and heat-exchanged by the heat exchanger, and then blown out into the room through the air outlet.
　ところで、室内機が設置される場所の環境条件は、場所毎に異なっている。すると、特許文献１のように、天面にのみならず下面にも吸込口を有している室内機では、該室内機の設置される場所の環境条件によっては、空気は主に天面の吸込口から吸い込まれることとなり、一方で下面の吸込口からはほとんど吸い込まれないといった現象が生じてしまう場合がある。特に、壁掛タイプの室内機は、室内でも比較的天井に近い部分に設置され、室内機の天面と天井との隙間が狭くなることが多い。その結果、室内機の天面と天井との隙間が大きい状態において性能評価する場合と比べ、室内機の性能のばらつきが生じてしまう。
　そこで、本発明の課題は、環境条件が異なるために場合によっては下面の吸込口が機能しないといった現象の発生を抑えることにある。 By the way, the environmental conditions of the place where an indoor unit is installed differ for every place. Then, as in Patent Document 1, in an indoor unit having a suction port not only on the top surface but also on the bottom surface, depending on the environmental conditions of the place where the indoor unit is installed, the air is mainly on the top surface. It will be sucked in from the suction port, and on the other hand, the phenomenon that it is hardly sucked from the suction port on the lower surface may occur. In particular, wall-mounted indoor units are installed in a portion that is relatively close to the ceiling even indoors, and the gap between the top surface of the indoor unit and the ceiling is often narrow. As a result, the performance of the indoor unit varies as compared with the case where the performance evaluation is performed in a state where the gap between the ceiling and the ceiling of the indoor unit is large.
Therefore, an object of the present invention is to suppress the occurrence of a phenomenon in which the suction port on the lower surface does not function depending on circumstances because environmental conditions are different.
　本発明の第１観点に係る空調室内機は、壁掛タイプの空調室内機であって、ケーシングと、ファンと、熱交換器と、吸込抵抗部とを備える。ケーシングは、天面吸込口と、下面吸込口とを有する。天面吸込口は、天面の前側から後側にかけて設けられている。下面吸込口は、下面に設けられている。ファンは、ケーシング内部に位置しており、天面吸込口及び下面吸込口から吸い込まれる空気の流れを生成する。熱交換器は、ケーシング内部にて、前側熱交換部と後側熱交換部とが側面視において略逆Ｖ字型に組み合わされることで形成されている。前側熱交換部は、ファンの前方を覆い、後側熱交換部は、ファンの後側を覆う。吸込抵抗部は、天面吸込口から吸い込まれる空気の流れを阻害する。更には、吸込抵抗部は、前側熱交換部に対応する天面吸込口の部分における吸込抵抗よりも、後側熱交換部に対応する天面吸込口の部分における吸込抵抗を大きくする。そして、ファンは、天面吸込口及び下面吸込口から吸い込まれて後側熱交換部に流入する空気の流れを生成する。吸込抵抗部は、後側熱交換部に対応する天面吸込口に位置している。 The air conditioning indoor unit according to the first aspect of the present invention is a wall-hanging type air conditioning indoor unit, and includes a casing, a fan, a heat exchanger, and a suction resistance unit. The casing has a top surface suction port and a bottom surface suction port. The top surface suction port is provided from the front side to the rear side of the top surface. The lower surface suction port is provided on the lower surface. The fan is located inside the casing, and generates a flow of air sucked from the top surface suction port and the bottom surface suction port. The heat exchanger is formed by combining a front heat exchange part and a rear heat exchange part in a substantially inverted V shape in a side view inside the casing. The front heat exchange part covers the front of the fan, and the rear heat exchange part covers the rear side of the fan. The suction resistance unit obstructs the flow of air sucked from the top surface suction port. Further, the suction resistance portion increases the suction resistance at the top surface suction port portion corresponding to the rear heat exchange portion rather than the suction resistance at the top surface suction port portion corresponding to the front side heat exchange portion. And a fan produces | generates the flow of the air suck | inhaled from a top | upper surface suction inlet and a lower surface suction inlet, and flows in into a rear side heat exchange part. The suction resistance unit is located at the top surface suction port corresponding to the rear heat exchange unit.

Therefore, even when an air-conditioning indoor unit is installed under an environmental condition that increases the indoor air sucked from the top surface suction port, the increase in the indoor air sucked from the top surface suction port To some extent. Therefore, the degree of variation in the ratio between the amount of room air sucked from the top surface suction port and the amount of room air sucked from the bottom surface suction port can be reduced, and the lower surface suction port does not function depending on circumstances because the environmental conditions are different. Occurrence of the phenomenon can be suppressed.

　なお、図２では、一例として、前側熱交換部１３ａ，１３ｂが、室内ファン１５の前方において更に折り曲げられた形状を有している場合を表している。即ち、前側熱交換部１３ａ，１３ｂは、上下方向において下方に位置する部分（即ち、前側熱交換部１３ａ）と上方に位置する部分（即ち、前側熱交換部１３ｂ）とに分かれて構成されている。しかし、前側熱交換部１３ａ，１３ｂは、室内ファン１５の前方を覆うように位置していればよく、図２に示すように上下方向に分かれた構成でなくともよい。 In particular, as shown in FIG. 2, the indoor heat exchanger 13 according to the present embodiment has a substantially inverted V shape in which both ends are bent downward in a side view, and an indoor fan 15 is disposed below the indoor heat exchanger 13. positioned. In the present embodiment, for convenience of the following description, among the indoor heat exchanger 13 having such a shape, the heat exchange part that covers the front of the indoor fan 15 is referred to as “front heat exchange parts 13a and 13b”. The heat exchange part that covers the rear side of the fan 15 is referred to as a “rear heat exchange part 13c”. That is, the indoor heat exchanger 13 according to the present embodiment has a substantially inverted V shape in which the front heat exchange units 13a and 13b and the rear heat exchange unit 13c are connected at the apex 13d.
In FIG. 2, as an example, the front heat exchange units 13 a and 13 b have a shape that is further bent in front of the indoor fan 15.

Yes. However, the front heat exchanging parts 13a and 13b only need to be positioned so as to cover the front of the indoor fan 15, and may not be configured to be vertically separated as shown in FIG.
　　（１－３）室内ファン
　室内ファン１５は、ケーシング１１の内部に位置しており、図１に示すＷ方向に細長い略円筒形状のクロスフローファンである。室内ファン１５は、駆動することで、天面吸込口２１及び下面吸込口２２それぞれから吸い込まれて室内熱交換器１３（具体的には、前側熱交換部１３ａ，１３ｂ及び後側熱交換部１３ｃ）に流入した後、該熱交換器１３を通過して吹出口２３から室内へと供給されるといった、室内空気の流れを生成する（図２の点線の矢印Ａ，Ｂ，Ｃを参照）。
　この室内ファン１５は、その駆動軸が室内ファンモータ（図示せず）の出力軸に接続されている。室内ファンモータが駆動した際、該モータの出力が出力軸を介して室内ファン１５の駆動軸へと伝達されることで、室内ファン１５は駆動することができる。 (1-3) Indoor Fan The indoor fan 15 is located in the casing 11 and is a substantially cylindrical cross flow fan that is elongated in the W direction shown in FIG. The indoor fan 15 is driven to be sucked in from the top surface suction port 21 and the bottom surface suction port 22, respectively, and the indoor heat exchanger 13 (specifically, the front side heat exchange units 13 a and 13 b and the rear side heat exchange unit 13 c). ), And then flows through the heat exchanger 13 and is supplied into the room through the outlet 23 (see dotted arrows A, B, and C in FIG. 2).
The drive shaft of the indoor fan 15 is connected to the output shaft of an indoor fan motor (not shown). When the indoor fan motor is driven, the output of the motor is transmitted to the drive shaft of the indoor fan 15 via the output shaft, so that the indoor fan 15 can be driven.
　　（１－４）底フレーム
　底フレーム１７は、底部分１７ａと流路形成部分１７ｂとで構成されている。
　底部分１７ａは、ケーシング１１の下面の少なくとも一部を構成する要素であって、底フレーム１７のうち空調室内機１００の外部に露出している。そのため、空調室内機１００の下面視において、ユーザは、底部分１７ａを目視することができる。
　流路形成部分１７ｂは、底フレーム１７のうち、ケーシング１１の内部に位置する要素である。流路形成部分１７ｂは、底部分１７ａの一端から上方に延びており、且つ室内ファン１５の形状に沿って湾曲した形状を有している。
　　（１－５）フィルタ
　フィルタ２５は、主としてケーシング１１の天面板１１ａと室内熱交換器１３との間、つまりは室内熱交換器１３に対して室内空気の流れ方向の上流側に配置されており、ケーシング１１の内部に着脱可能に装着される。フィルタ２５は、前側熱交換部１３ａ，１３ｂ及び後側熱交換部１３ｃを覆っている。そして、フィルタ２５は、フィルタ２５の前後方向における後側端部２５ｂが、室内熱交換器１３の頂点１３ｄよりも下方に位置する形状を有している。より詳細には、本実施形態に係るフィルタ２５は、その略中央の部分がケーシング１１の天面板１１ａに沿って延びており、更にはその前後方向における前側端部２５ａ及び後側端部２５ｂが室内熱交換器１３の頂点１３ｄよりも下方に垂れ下がっていることで室内熱交換器１３の上方を覆う、いわゆる略逆Ｕ字形状を有している。 (1-4) Bottom Frame The bottom frame 17 includes a bottom portion 17a and a flow path forming portion 17b.
The bottom portion 17 a is an element that constitutes at least a part of the lower surface of the casing 11, and is exposed to the outside of the air conditioning indoor unit 100 in the bottom frame 17. Therefore, in the bottom view of the air conditioning indoor unit 100, the user can visually observe the bottom portion 17a.
The flow path forming portion 17 b is an element located inside the casing 11 in the bottom frame 17. The flow path forming portion 17 b extends upward from one end of the bottom portion 17 a and has a shape curved along the shape of the indoor fan 15.
(1-5) Filter The filter 25 is mainly disposed between the top plate 11a of the casing 11 and the indoor heat exchanger 13, that is, upstream of the indoor heat exchanger 13 in the flow direction of the indoor air. It is detachably mounted inside the casing 11. The filter 25 covers the front heat exchange units 13a and 13b and the rear heat exchange unit 13c. And the filter 25 has the shape where the rear side edge part 25b in the front-back direction of the filter 25 is located below the vertex 13d of the indoor heat exchanger 13. More specifically, the filter 25 according to the present embodiment has a substantially central portion extending along the top plate 11a of the casing 11, and further includes a front end 25a and a rear end 25b in the front-rear direction. It has a so-called substantially inverted U shape that covers the upper side of the indoor heat exchanger 13 by hanging downward from the apex 13 d of the indoor heat exchanger 13.
　なお、本実施形態では、フィルタ２５の後側端部２５ｂは、後側熱交換部１３ｃをほぼ覆う位置にまで達しており、フィルタ２５の前側端部２５ａは、前側熱交換部１３ｂ全てを覆いつつ、且つ前側熱交換部１３ａの上部を部分的に覆う位置にまで達している。これにより、後側熱交換部１３ｃに対応するフィルタ２５の部分は、主に下面吸込口２２から吸い込まれた室内空気から塵埃を除去することができる。前側熱交換部１３ａ，１３ｂに対応するフィルタ２５の部分は、主に天面吸込口２１から吸い込まれた室内空気から塵埃を除去することができる。即ち、フィルタ２５は、室内熱交換器１３の表面が室内空気中の塵埃によって汚染されるのを防ぐためのものであると言うことができる。
　このようなフィルタ２５は、例えば、樹脂製の糸で平織りまたは綾織された網であって、環形状（つまり、無端ベルト状）に成形されており、支持枠（図示せず）に掛け渡されている。支持枠に掛け渡されたフィルタ２５は、図３に示すように、空調室内機１００の正面視において右側と左側とに、並ぶようにして２つ設けられている。これらのフィルタ２５には、一般のフィルタに見られるような補強用の縁やリブが設けられていないため、フィルタ２５は、自身で安定した形状を維持することができない。そのため、フィルタ２５は支持枠に掛け渡されることで、環形状の形状を保っている。 In the present embodiment, the rear end portion 25b of the filter 25 reaches a position that substantially covers the rear heat exchange portion 13c, and the front end portion 25a of the filter 25 covers the entire front heat exchange portion 13b. However, it has reached a position that partially covers the upper portion of the front heat exchange section 13a. Thereby, the part of the filter 25 corresponding to the rear side heat exchange part 13c can remove dust from the indoor air mainly sucked from the lower surface suction port 22. The part of the filter 25 corresponding to the front heat exchange units 13 a and 13 b can remove dust from the indoor air mainly sucked from the top surface suction port 21. That is, it can be said that the filter 25 is for preventing the surface of the indoor heat exchanger 13 from being contaminated by dust in the indoor air.
Such a filter 25 is, for example, a net woven or twilled with a resin thread, is formed in a ring shape (that is, an endless belt shape), and is stretched over a support frame (not shown). ing. As shown in FIG. 3, two filters 25 laid across the support frame are provided so as to be arranged on the right side and the left side in the front view of the air conditioning indoor unit 100. Since these filters 25 are not provided with reinforcing edges and ribs as found in general filters, the filters 25 cannot maintain a stable shape by themselves. For this reason, the filter 25 is stretched over the support frame to maintain an annular shape.
　　（１－６）清掃ユニット
　清掃ユニット３０は、図５に示すように、ケーシング１１内部において、フィルタ２５付近、より具体的にはフィルタ２５の下部の折り返し部分近傍に位置している。清掃ユニット３０は、フィルタ２５の清掃のみならず、フィルタ２５を直接清掃するブラシ３３（後述）の清掃も行うものであって、図２～６に示すように、清掃ユニット用フレーム３１、フィルタ駆動部３２、ブラシ３３、ブラシ駆動部３４、ブラシ清掃部３５、塵埃受け部３７及び圧縮ローラ３８を有している。
　清掃ユニット用フレーム３１は、図４に示すように、空調室内機１００の長手方向(図１のＷ方向）に沿った細長い形状を有しており、その内部にはブラシ３３が着脱可能に取りつけられている。また、図５に示すように、清掃ユニット用フレーム３１の上面には、開口部３１ａが形成されており、清掃ユニット用フレーム３１は、フィルタ２５下部の折り返し部分の更に下方に位置している。そのため、該フレーム３１の開口部３１ａを介してブラシ３３の一部が、清掃ユニット用フレーム３１の上方の空間に露出しつつ、且つ開口部３１ａを介してフィルタ２５に直接接触できるようになっている。 (1-6) Cleaning Unit As shown in FIG. 5, the cleaning unit 30 is located in the casing 11 in the vicinity of the filter 25, more specifically, in the vicinity of the folded portion at the bottom of the filter 25. The cleaning unit 30 not only cleans the filter 25 but also cleans a brush 33 (to be described later) that directly cleans the filter 25. As shown in FIGS. A part 32, a brush 33, a brush drive part 34, a brush cleaning part 35, a dust receiving part 37, and a compression roller 38.
As shown in FIG. 4, the cleaning unit frame 31 has an elongated shape along the longitudinal direction of the air conditioning indoor unit 100 (W direction in FIG. 1), and a brush 33 is detachably mounted therein. It has been. As shown in FIG. 5, an opening 31 a is formed on the upper surface of the cleaning unit frame 31, and the cleaning unit frame 31 is located further below the folded portion at the lower part of the filter 25. Therefore, a part of the brush 33 is exposed to the space above the cleaning unit frame 31 through the opening 31a of the frame 31, and can directly contact the filter 25 through the opening 31a. Yes.
　フィルタ駆動部３２は、フィルタ２５を周回させるものであって、ローラ３２ａやローラ用モータ（図示せず）等で構成される。ローラ３２ａの周面には、いわゆるパイル織りされた織物基布が貼り付けられている。ローラ３２ａの周面における織物基布はフィルタ２５の網目に入り込んでおり、ローラ３２ａとフィルタ２５との間には滑りが生じ難くなっている。ローラ用モータは、その出力軸がローラ３２ａの回転軸に接続されている。ローラ用モータが駆動することで、ローラ３２ａが回転し、フィルタ２５が周回することができるようになる。
　ブラシ３３は、図４に示すように、清掃ユニット用フレーム３１と同様、空調室内機１００の長手方向に沿って細長い形状を有しており、長手方向に直交する断面が略円形の形状を有している。ブラシ３３は、フィルタ２５に直接接触することにより、フィルタ２５から塵埃を除去する。このようなブラシ３３は、図５に示すように、芯材３３ａと、芯材３３ａの周面に設けられた複数の線材３３ｂとによって構成されており、線材３３ｂは、フィルタ２５に接触可能な長さを有している。また、ブラシ３３は、清掃ユニット用フレーム３１に対して回転可能に設けられている。 The filter driving unit 32 circulates the filter 25 and includes a roller 32a, a roller motor (not shown), and the like. A so-called pile-woven fabric base fabric is affixed to the peripheral surface of the roller 32a. The fabric base fabric on the peripheral surface of the roller 32 a enters the mesh of the filter 25, and slippage hardly occurs between the roller 32 a and the filter 25. The output shaft of the roller motor is connected to the rotation shaft of the roller 32a. When the roller motor is driven, the roller 32a rotates and the filter 25 can go around.
As shown in FIG. 4, the brush 33 has an elongated shape along the longitudinal direction of the air conditioning indoor unit 100 as in the cleaning unit frame 31, and a cross section perpendicular to the longitudinal direction has a substantially circular shape. is doing. The brush 33 removes dust from the filter 25 by directly contacting the filter 25. As shown in FIG. 5, the brush 33 includes a core member 33 a and a plurality of wire members 33 b provided on the peripheral surface of the core member 33 a, and the wire member 33 b can contact the filter 25. It has a length. The brush 33 is provided so as to be rotatable with respect to the cleaning unit frame 31.
　ブラシ駆動部３４は、ブラシ３３を回転させるためのものであって、例えばステッピングモータで構成される。つまり、モータであるブラシ駆動部３４の出力軸は、ブラシ３３の回転軸に接続されており、ブラシ３３は、ステッピングモータが駆動することで回転することができる。例えば、ブラシ３３が回転する際は、フィルタ２５の移動が停止し、逆にフィルタ２５が移動している際は、ブラシ３３は回転を停止した状態となる。即ち、フィルタ駆動部３２及びブラシ駆動部３４は、フィルタ２５またはブラシ３３を相対的に移動させることができる。
　ブラシ清掃部３５は、図４に示すように、清掃ユニット用フレーム３１に取り付けられている。ブラシ清掃部３５は、図５に示すように、ブラシ３３の回転軸方向に沿って配置され、かつ清掃ユニット用フレーム３１の背面からブラシ３３に向けて突出しており、更にはブラシ３３の回転方向（つまり、図５のブラシ３３部分における矢印の方向）に逆らうようにして傾斜している。これにより、ブラシ清掃部３５は、ブラシ３３が図５の矢印の方向に回転する場合、ブラシ３３の線材３３ｂの間の塵埃を掻き落とすことができる。 The brush drive unit 34 is for rotating the brush 33, and is composed of, for example, a stepping motor. That is, the output shaft of the brush drive unit 34, which is a motor, is connected to the rotation shaft of the brush 33, and the brush 33 can be rotated by driving the stepping motor. For example, when the brush 33 rotates, the movement of the filter 25 stops, and conversely, when the filter 25 moves, the brush 33 stops rotating. That is, the filter driving unit 32 and the brush driving unit 34 can relatively move the filter 25 or the brush 33.
As shown in FIG. 4, the brush cleaning unit 35 is attached to the cleaning unit frame 31. As shown in FIG. 5, the brush cleaning unit 35 is disposed along the rotation axis direction of the brush 33, protrudes from the back surface of the cleaning unit frame 31 toward the brush 33, and further rotates in the rotation direction of the brush 33. In other words, it is inclined to oppose (in the direction of the arrow in the brush 33 portion of FIG. 5). Thereby, the brush cleaning part 35 can scrape off the dust between the wire 33b of the brush 33, when the brush 33 rotates in the direction of the arrow of FIG.
　塵埃受け部３７は、図２，５に示すように、清掃ユニット用フレーム３１に取り付けられた状態でブラシ３３及びブラシ清掃部３５の下方に配置される。塵埃受け部３７内には、ブラシ清掃部３５によってブラシ３３から掻き落とされた塵埃が貯められる。また、塵埃受け部３７は、清掃ユニット用フレーム３１に対し着脱可能に取り付けられているため、ユーザは、塵埃受け部３７を清掃ユニット用フレーム３１及びケーシング１１から取り出して、塵埃受け部３７内にたまった塵埃を容易に処理することができる。
　圧縮ローラ３８は、円柱状の棒状部材であって、清掃ユニット用フレーム３１に回転可能に支持されている。ここでは、圧縮ローラ３８は、図５に示すように、ブラシ清掃部３５の付近において、ブラシ３３に接触するようにして位置している。これにより、ブラシ３３が図５の矢印の方向へと回転した際、このブラシ３３の回転に追従して、ブラシ３３の回転方向とは逆の方向に回転する。この圧縮ローラ３８により、塵埃受け部３７内に溜まった塵埃は圧縮されるため、塵埃受け部３７内には塵埃が比較的多く入るようになる。更に、圧縮ローラ３８の回転により、比較的粘度の高い塵埃は、塵埃受け部３７へと確実に送られる。 As shown in FIGS. 2 and 5, the dust receiving portion 37 is disposed below the brush 33 and the brush cleaning portion 35 while being attached to the cleaning unit frame 31. In the dust receiving part 37, the dust scraped off from the brush 33 by the brush cleaning part 35 is stored. Further, since the dust receiving part 37 is detachably attached to the cleaning unit frame 31, the user takes out the dust receiving part 37 from the cleaning unit frame 31 and the casing 11 and puts it in the dust receiving part 37. Accumulated dust can be easily treated.
The compression roller 38 is a cylindrical bar-like member, and is rotatably supported by the cleaning unit frame 31. Here, the compression roller 38 is positioned in contact with the brush 33 in the vicinity of the brush cleaning unit 35 as shown in FIG. Thus, when the brush 33 rotates in the direction of the arrow in FIG. 5, the brush 33 follows the rotation of the brush 33 and rotates in the direction opposite to the rotation direction of the brush 33. Since the dust accumulated in the dust receiving portion 37 is compressed by the compression roller 38, a relatively large amount of dust enters the dust receiving portion 37. Further, due to the rotation of the compression roller 38, relatively high-viscosity dust is reliably sent to the dust receiver 37.
　　（１－７）支持部材
　支持部材４０は、図２に示すように、前側熱交換部１３ａ，１３ｂ及び後側熱交換部１３ｃの上方に位置し、図３，６に示すように、清掃ユニット３０の一部分であるフィルタ駆動部３２及びブラシ駆動部３４を支持する。そして、フィルタ２５の空調室内機１００への装着の際、フィルタ２５は、支持部材４０に沿ってケーシング１１の正面側から内部へと差し込まれることとなるが、支持部材４０は、該フィルタ２５をケーシング１１の背面側へと導くと共に該フィルタ２５を支持する。更に、支持部材４０は、該部材４０の下方側の端部であると共に前後方向における後側の端部でもある後側端部４０ｂが、室内熱交換器１３の頂点１３ｄよりも後側且つ下方に位置する形状を有している。
　より具体的には、支持部材４０は、その略中央の部分がケーシング１１の天面板１１ａに沿って延びており、更にはその前後方向における前側端部４０ａ及び後側端部４０ｂが室内熱交換器１３の頂点１３ｄよりも下方に垂れ下がっていることで室内熱交換器１３の上方を覆う形状を有している。即ち、前側端部４０ａ及び後側端部４０ｂのみに着目すると、支持部材４０は、いわゆる略逆Ｕ字型の形状を有している。 (1-7) Support Member As shown in FIG. 2, the support member 40 is located above the front heat exchange units 13a and 13b and the rear heat exchange unit 13c, and as shown in FIGS. The filter driving unit 32 and the brush driving unit 34, which are a part of 30, are supported. When the filter 25 is attached to the air conditioning indoor unit 100, the filter 25 is inserted from the front side of the casing 11 along the support member 40 into the inside. The filter 25 is supported while being guided to the back side of the casing 11. Further, the support member 40 is a lower end of the member 40 and a rear end 40b which is also a rear end in the front-rear direction. The rear end 40b is lower and lower than the apex 13d of the indoor heat exchanger 13. It has the shape located in.
More specifically, the support member 40 has a substantially central portion extending along the top plate 11a of the casing 11, and the front end 40a and the rear end 40b in the front-rear direction are indoor heat exchanges. It has the shape which covers the upper direction of the indoor heat exchanger 13 by hanging below the vertex 13d of the vessel 13. That is, paying attention only to the front end 40a and the rear end 40b, the support member 40 has a so-called substantially inverted U-shape.
　そして、図３，６に示すように、支持部材４０は、該部材４０の左右方向のほぼ中央を前後方向に延びる仕切部４１を挟んで位置する左側部分４２と右側部分４３とを有するが、図３に示すように、支持枠に掛け渡されたフィルタ２５は、該部分４２，４３それぞれの上面に装着される。フィルタ２５は、ケーシング１１への装着の際、まずは図６の状態にてケーシング１１の正面側からケーシング１１内へと差し込まれ、フィルタ２５の後側端部２５ｂが支持部材４０の後側端部４０ｂ付近に至るまで、支持部材４０の左側部分４２及び右側部分４３の上面に沿ってスライドする。これにより、フィルタ２５は、図３に示すように支持部材４０の上面に装着される。そのため、図６に示すように、支持部材４０の正面視において、左側部分４２及び右側部分４３それぞれの左右端部４２ａ，４２ｂ，４３ａ，４３ｂには、支持枠に掛け渡されたフィルタ２５の端面が対峙すると共に該フィルタ２５がスライドするためのスライド機構が設けられている。スライド機構は、詳細には、溝や複数の突起等で形成されている。即ち、左側部分４２及び右側部分４３それぞれの左右端部４２ａ，４２ｂ，４３ａ，４３ｂにおけるスライド機構は、フィルタ２５を支持部材４０上にて移動させるための構成であると言うことができ、フィルタ２５のケーシング１１への装着時のみならず、フィルタ２５の清掃時においてフィルタ２５を移動させる場合にも有益な構成である。 As shown in FIGS. 3 and 6, the support member 40 includes a left side portion 42 and a right side portion 43 that are positioned with a partition portion 41 extending in the front-rear direction at a substantially center in the left-right direction of the member 40. As shown in FIG. 3, the filter 25 spanned on the support frame is mounted on the upper surfaces of the portions 42 and 43. When the filter 25 is mounted on the casing 11, first, in the state of FIG. 6, the filter 25 is inserted into the casing 11 from the front side of the casing 11, and the rear end 25 b of the filter 25 is the rear end of the support member 40. It slides along the upper surface of the left part 42 and the right part 43 of the support member 40 until it reaches the vicinity of 40b. Thus, the filter 25 is mounted on the upper surface of the support member 40 as shown in FIG. Therefore, as shown in FIG. 6, in the front view of the support member 40, the left and right end portions 42 a, 42 b, 43 a, and 43 b of the left portion 42 and the right portion 43 are end surfaces of the filter 25 that spans the support frame. And a sliding mechanism for sliding the filter 25 is provided. Specifically, the slide mechanism is formed of a groove, a plurality of protrusions, and the like. That is, it can be said that the slide mechanism at the left and right end portions 42a, 42b, 43a, 43b of the left portion 42 and the right portion 43 is a configuration for moving the filter 25 on the support member 40. This is a useful configuration not only when the filter 25 is mounted on the casing 11 but also when the filter 25 is moved when the filter 25 is cleaned.
　　（１－８）吸込抵抗部
　吸込抵抗部５０は、天面吸込口２１から吸い込まれる空気の流れを阻害するためのものであって、図２，７，８に示すように、後側熱交換部１３ｃに対応する天面吸込口２１付近に位置している。ここで、図７は、図２において、ケーシング１１内部のうち天面板１１ａ付近の断面を拡大したものであって、図２からは支持部材４０やフィルタ２５を省略している。図８は、空調室内機１００を上から見た場合の、天面板１１ａ付近の図である。
　より詳細には、本実施形態に係る吸込抵抗部５０は、ケーシング１１を構成する天面板１１ａや前面板１１ｂ、背面板１１ｃとは別部材で構成されており、後側熱交換部１３ｃに対応する天面吸込口２１の後側部分２１ａに装着されている。つまり、吸込抵抗部５０は、天面吸込口２１のうち、室内ファン１５の後方側であってかつその上方に位置する別部材と言うことができる。更に言い換えると、吸込抵抗部５０は、後側熱交換器１３ｃの上方であると共に空調室内機１００の前後方向において室内熱交換器１３の頂点１３ｄよりも後方側に位置しているが、その中でも天面吸込口２１の中央寄りに位置しているのではなく、背面板１１ｃ側に位置している別部材だとも言える。ここで、天面吸込口２１の後側部分２１ａとは、室内熱交換器１３の頂点１３ｄからケーシング１１の背面板１１ｄまでの間の部分を言う。従って、図８に示すように、後側部分２１ａに対応するケーシング１１内部には、後側熱交換部１３ｃが位置しており、逆に室内熱交換器１３の頂点１３ｄからケーシング１１の前面板１１ｂまでの間である前側部分２１ｂに対応するケーシング１１内部には、前側熱交換部１３ａ，１３ｂが位置している。 (1-8) Suction resistance portion The suction resistance portion 50 is for inhibiting the flow of air sucked from the top surface suction port 21, and as shown in FIGS. It is located in the vicinity of the top surface inlet 21 corresponding to the part 13c. Here, FIG. 7 is an enlarged view of the section near the top plate 11a in the casing 11 in FIG. 2, and the support member 40 and the filter 25 are omitted from FIG. FIG. 8 is a view of the vicinity of the top panel 11a when the air conditioning indoor unit 100 is viewed from above.
More specifically, the suction resistance unit 50 according to the present embodiment is configured as a separate member from the top plate 11a, the front plate 11b, and the back plate 11c constituting the casing 11, and corresponds to the rear heat exchange unit 13c. It is attached to the rear portion 21a of the top surface suction port 21. That is, the suction resistance portion 50 can be said to be a separate member located behind and above the indoor fan 15 in the top surface suction port 21. Furthermore, in other words, the suction resistance portion 50 is located above the rear heat exchanger 13c and rearward of the apex 13d of the indoor heat exchanger 13 in the front-rear direction of the air conditioning indoor unit 100. It can be said that it is a separate member located on the back plate 11c side rather than being located near the center of the top surface suction port 21. Here, the rear portion 21 a of the top surface inlet 21 refers to a portion between the apex 13 d of the indoor heat exchanger 13 and the back plate 11 d of the casing 11. Therefore, as shown in FIG. 8, the rear heat exchange portion 13 c is located inside the casing 11 corresponding to the rear portion 21 a, and conversely, from the top 13 d of the indoor heat exchanger 13 to the front plate of the casing 11. The front heat exchange parts 13a and 13b are located inside the casing 11 corresponding to the front part 21b that is between 11b and 11b.
　なお、吸込抵抗部５０の材質は、ケーシング１１の材質と同様、例えば樹脂で構成することができる。または、吸込抵抗部５０は、金属等で構成されることもできる。
　そして、吸込抵抗部５０は、左右方向においては、天面吸込口２１の長手方向（即ち、図８のＷ方向）の全長に渡って設けられており、図８に示すように、空調室内機１００の上面視において、左右方向に細長い略矩形の形状を有している。
　なお、本実施形態に係る図２，７，８では、一例として、吸込抵抗部５０が、ケーシング１１の背面板１１ｃと隙間なく接しており、且つケーシング１１の正面側（つまり、ケーシング１１の前面板１１ｂ側）へと延びている場合を表している。更に、図８では、一例として、吸込抵抗部５０が、ケーシング１１の左側端部１１ｄ及び右側端部１１ｅの両方と接している場合を表している。 In addition, the material of the suction resistance part 50 can be comprised with resin similarly to the material of the casing 11, for example. Or the suction resistance part 50 can also be comprised with a metal etc.
And the suction resistance part 50 is provided over the full length of the top | upper surface suction inlet 21 in the left-right direction (namely, the W direction of FIG. 8), and as shown in FIG. In a top view of 100, it has a substantially rectangular shape elongated in the left-right direction.
2, 7, and 8 according to the present embodiment, as an example, the suction resistance portion 50 is in contact with the back plate 11 c of the casing 11 without a gap, and the front side of the casing 11 (that is, the front of the casing 11). The case where it extends to the face plate 11b side) is shown. Further, FIG. 8 shows a case where the suction resistance portion 50 is in contact with both the left end portion 11d and the right end portion 11e of the casing 11 as an example.
　このように、吸込抵抗部５０が天面吸込口２１の後側部分２１ａを塞ぐことで、天面吸込口２１の後側部分２１ａから吸い込まれる室内空気の量が少なくなり、ケーシング１１の天面からケーシング１１内部へと吸い込まれる室内空気は、主に塞がれていない天面吸込口２１の部分（詳細には、前側部分２１ｂや塞がれていない後側部分２１ａの一部分）を介して吸い込まれることとなる。そのため、仮に吸込抵抗部５０が備えられていなければ天面吸込口２１から吸い込まれる室内空気が増加してしまうような環境条件下に、本実施形態に係る空調室内機１００が設置されても、天面吸込口２１から吸込まれる室内空気の増加分は、吸込抵抗部５０によってある程度抑えられることとなる。
　なお、上記「環境条件」とは、空調室内機１００が設置される場所がどのような環境であるのかを表す条件である。環境条件としては、例えば空調室内機１００の設置場所における室内の天井と該室内機１００の天面との距離が比較的狭いこと等が挙げられる。 As described above, the suction resistance portion 50 blocks the rear portion 21a of the top surface suction port 21, so that the amount of room air sucked from the rear portion 21a of the top surface suction port 21 is reduced, and the top surface of the casing 11 is reduced. The indoor air sucked into the casing 11 from the inside mainly passes through the portion of the top surface inlet 21 that is not blocked (specifically, the front portion 21b and a portion of the rear portion 21a that is not blocked). It will be sucked. Therefore, even if the air conditioning indoor unit 100 according to the present embodiment is installed under an environmental condition in which the indoor air sucked from the top surface suction port 21 increases unless the suction resistance unit 50 is provided, The increase in room air sucked from the top surface suction port 21 is suppressed to some extent by the suction resistance unit 50.
The “environmental condition” is a condition indicating what kind of environment the place where the air conditioning indoor unit 100 is installed. Examples of the environmental condition include a relatively narrow distance between the indoor ceiling at the place where the air conditioning indoor unit 100 is installed and the top surface of the indoor unit 100.
　ここで、吸込抵抗部５０が、天面吸込口２１の後側部分２１ａをどの程度塞ぐかについて説明する。本実施形態に係る吸込抵抗部５０は、空調室内機１００が設置される環境条件が実際にどのような条件であるかに関わらず、下面吸込口２２から吸い込まれる空気の風速が約０．５ｍ／ｓｅｃ以上を保つ程度に、天面吸込口２１を塞ぐ。具体的には、天面吸込口２１の後側部分２１ａの面積を１００％とした場合、吸込抵抗部５０は、該後側部分２１ａの約３０％以上を塞ぐ。更に、吸込抵抗部５０は、該後側部分２１ａの約５０％以上を塞ぐことが好ましい。本実施形態に係る図２，７，８では、一例として、吸込抵抗部５０が後側部分２１ａの約６０％を塞いでいる場合を表している。
　これにより、天面吸込口２１から吸い込まれる室内空気の量と下面吸込口２２から吸い込まれる室内空気の量との比率が、空調室内機１００が設置される環境条件に依存してばらついてしまうのを、確実に抑えることができる。従って、天面吸込口２１から吸い込まれる室内空気の量と下面吸込口２２から吸い込まれる室内空気の量との比率のばらつき度合いを小さくでき、空調室内機１００が設置される環境条件が異なるために、場合によっては下面吸込口２２が機能しないといった現象の発生を抑えることができる。 Here, how much the suction resistance portion 50 blocks the rear portion 21a of the top surface suction port 21 will be described. The suction resistance unit 50 according to the present embodiment has an air velocity of about 0.5 m from the lower surface suction port 22 regardless of the actual environmental conditions in which the air conditioning indoor unit 100 is installed. The top suction port 21 is closed to such an extent that it keeps at least / sec. Specifically, when the area of the rear portion 21a of the top surface suction port 21 is 100%, the suction resistance portion 50 closes about 30% or more of the rear portion 21a. Furthermore, it is preferable that the suction resistance portion 50 covers about 50% or more of the rear portion 21a. 2, 7, and 8 which concern on this embodiment represent the case where the suction resistance part 50 has obstruct | occluded about 60% of the rear side parts 21a as an example.
As a result, the ratio between the amount of room air sucked from the top surface suction port 21 and the amount of room air sucked from the bottom surface suction port 22 varies depending on the environmental conditions in which the air conditioning indoor unit 100 is installed. Can be reliably suppressed. Therefore, the degree of variation in the ratio between the amount of room air sucked from the top surface suction port 21 and the amount of room air sucked from the bottom surface suction port 22 can be reduced, and the environmental conditions in which the air conditioning indoor unit 100 is installed are different. In some cases, the phenomenon that the lower surface suction port 22 does not function can be suppressed.
　なお、吸込抵抗部５０が天面吸込口２１の後側部分２１ａをどの程度塞ぐかの具体的数値については、室内ファン１５の風量を最小風量とする条件、該後側部分２１ａの約３０％以上または約５０％以上を塞ぐといった条件、下面吸込口２２から吸い込まれる空気の風速が約０．５ｍ／ｓｅｃ以上となる条件に加え、更に圧力損失等を考慮して、机上計算、シミュレーション及び実験等を基に、適宜決定される。
　（１－９）その他の構成
　上述した他に、空調室内機１００は、該室内機１００を構成する各種機器の制御を行う室内制御部（図示せず）を備えている。室内制御部は、ＣＰＵ及びメモリで構成されるマイクロコンピュータであって、ケーシング１１の前方部分に収まっている。例えば、室内制御部は、フラップ用モータ及び室内ファンモータと接続されており、これらのモータの駆動制御を行うことで、水平フラップ２３ａの開閉制御や角度制御、室内ファン１５の風量制御等を行う。 In addition, about the concrete numerical value of how much the suction resistance part 50 block | closes the rear side part 21a of the top | upper surface suction inlet 21, the conditions which make the air volume of the indoor fan 15 the minimum air volume, about 30% of this rear side part 21a In addition to the above conditions, or the condition that about 50% or more is blocked, the condition that the air velocity of the air sucked from the lower surface inlet 22 is about 0.5 m / sec or more, and further considering the pressure loss, etc., desktop calculations, simulations, and experiments It is determined appropriately based on the above.
(1-9) Other Configurations In addition to the above, the air conditioning indoor unit 100 includes an indoor control unit (not shown) that controls various devices constituting the indoor unit 100. The indoor control unit is a microcomputer including a CPU and a memory, and is housed in a front portion of the casing 11. For example, the indoor control unit is connected to a flap motor and an indoor fan motor, and controls the opening and closing of the horizontal flap 23a, angle control, and air volume control of the indoor fan 15 by performing drive control of these motors. .
　（２）特徴
　　（２－１）
　本実施形態に係る空調室内機１００には、天面吸込口２１と下面吸込口２２とが設けられているが、後側熱交換部１３ｃに対応する天面吸込口２１は、吸込抵抗部５０によって塞がれている。これにより、天面吸込口２１から吸い込まれる室内空気の量は、吸込抵抗部５０によって抑えられる。そのため、仮に吸込抵抗部５０が備えられていなければ天面吸込口２１から吸い込まれる室内空気が増加してしまうような環境条件下に、本実施形態に係る空調室内機１００が設置されても、天面吸込口２１から吸い込まれる室内空気の増加分は、吸込抵抗部５０によってある程度抑えられる。従って、天面吸込口２１から吸い込まれる室内空気の量と下面吸込口２２から吸い込まれる室内空気の量との比率のばらつき度合いを小さくでき、環境条件が異なるために場合によっては下面吸込口２２が機能しないといった現象の発生を抑えることができる。 (2) Features (2-1)
The air conditioning indoor unit 100 according to the present embodiment is provided with a top surface suction port 21 and a bottom surface suction port 22, but the top surface suction port 21 corresponding to the rear heat exchange unit 13 c is configured with a suction resistance unit 50. It is blocked by. Thus, the amount of room air sucked from the top surface suction port 21 is suppressed by the suction resistance unit 50. Therefore, even if the air conditioning indoor unit 100 according to the present embodiment is installed under an environmental condition in which the indoor air sucked from the top surface suction port 21 increases unless the suction resistance unit 50 is provided, The increase in room air sucked from the top surface suction port 21 is suppressed to some extent by the suction resistance unit 50. Therefore, the degree of variation in the ratio between the amount of room air sucked from the top surface suction port 21 and the amount of room air sucked from the bottom surface suction port 22 can be reduced. Occurrence of a phenomenon that does not function can be suppressed.
　更に、天面吸込口２１から吸い込まれる室内空気の量と下面吸込口２２から吸い込まれる室内空気の量との比率のばらつき度合いが小さくなることで、室内熱交換器１３に流れる室内空気の量の、環境条件に起因するばらつきも小さくなる。即ち、室内熱交換器１３に流れ込む室内空気の量は、空調室内機１００がどのような環境条件下に設置されているのかに限らず、ほぼ一定となることができる。従って、空調室内機１００の性能が設置場所によって異なってしまうことも、防ぐことができる。

Also, variations due to environmental conditions are reduced. That is, the amount of indoor air flowing into the indoor heat exchanger 13 is not limited to what environmental conditions the air conditioning indoor unit 100 is installed in, and can be substantially constant. Therefore, it is possible to prevent the performance of the air conditioning indoor unit 100 from being different depending on the installation location.

Therefore, the degree of variation in the ratio between the amount of room air sucked from the top surface suction port 21 and the amount of room air sucked from the bottom surface suction port 22 can be further reduced.

Further, the suction resistance portion 50 closes about 30% or more of the rear portion 21 a of the top surface suction port 21, so that the amount of room air sucked from the top surface suction port 21 and the room air sucked from the bottom surface suction port 22.
