Description

本発明は左右風向調整装置および空気調和機の室内機、特に、空気調和機の室内機に設置される左右風向調整装置、および左右風向調整装置が設置された空気調和機の室内機に関するものである。 The present invention relates to a left / right wind direction adjusting device and an air conditioner indoor unit, and more particularly to a left / right air direction adjusting device installed in an air conditioner indoor unit, and an air conditioner indoor unit in which a left / right air direction adjusting device is installed. is there.

従来の、空気調和機の室内機に設置される左右風向調整装置は、室内機の吹出口に近い断面矩形状の風路に設置されるものであって、左右方向に垂直な回動中心（略上下方向）を中心にして回動する複数の左右風向板を有している。そして、複数の左右風向板を左方向に大きく回動して、正面吹きから大きく左方向に逸れた斜め吹きを冷房運転時に実行したとき、冷房空気が吹出口を形成する左側の風路側壁に衝突し、当該左側の風路側壁に結露が生じることがあった。同様に、正面吹きから大きく右方向に逸れた斜め吹きを冷房運転時に実行したとき、右側の風路側壁への着露（結露）が生じることがあった。
このため、左側の風路側壁と最も左側に位置する左右風向板との間に、正面方向または斜め右方向に空調空気（冷房空気）を案内する回動しない左右風向板と、右側の風路側壁に近い位置と最も右側に位置する左右風向板との間に、正面方向または左方向に空調空気（冷房空気）を案内する回動しない左右風向板を有する風向調整装置が開示されている（例えば、特許文献１参照）。 A conventional left / right airflow direction adjusting device installed in an indoor unit of an air conditioner is installed in an air passage having a rectangular cross section close to an air outlet of the indoor unit, and has a rotation center perpendicular to the left / right direction ( It has a plurality of left and right wind direction plates that rotate about a substantially vertical direction). Then, when the plurality of left and right wind direction plates are largely rotated leftward and an oblique blow greatly deviating leftward from the front blow is performed during the cooling operation, the cooling air is applied to the left air passage side wall that forms the outlet. There was a case where condensation occurred on the left side air passage side wall. Similarly, when an oblique blow significantly deviating from the front blow to the right is performed during the cooling operation, dew condensation (condensation) may occur on the right air channel side wall.
For this reason, a non-rotating left and right wind direction plate that guides conditioned air (cooling air) in the front direction or diagonally right direction between the left wind channel side wall and the left and right wind direction plates located on the leftmost side, and the right wind channel There is disclosed a wind direction adjusting device having a non-rotating left and right wind direction plate for guiding conditioned air (cooling air) in a front direction or a left direction between a position close to the side wall and a left and right wind direction plate located on the rightmost side ( For example, see Patent Document 1).

実開平２−２４２３３号公報（第１頁、第３図）Japanese Utility Model Publication No. 2-24233 (first page, FIG. 3)

特許文献１に開示された左右風向調整装置は、複数の左右回動板を左方向（または右方向）に大きく回動して斜め吹きを冷房運転時に実行しても、吹出口を形成する左側（または右側）の側壁に近い範囲の風流れは、回動しない左右風向板によって正面方向に案内されるから、冷房空気の左側（または右側）の側壁への衝突が抑えられる。このため、冷房運転時における吹出口を形成する側壁への着露を抑えることができる。
しかしながら、特許文献１に開示された左右風向調整装置は、複数の左右回動板を回動自在に支持する装置基板に、回動しない左右風向板が一体的に形成されているため、以下の問題があった。
すなわち、空気調和機の機種や容量（能力）あるいは室内機の形式等に応じて、吹出口を形成する側壁への着露の形態が相違することから、空気調和機の機種や容量（能力）あるいは室内機の形式等毎に、回動しない左右風向板の最適な向きや最適な形状（大きさ等）が異なる。そのため、装置基板の形状それ自体は同じでありながら、装置基板に比較すると各段に小さいサイズである回動しない左右風向板の形状や方向が相違するだけで、多くの種類の「回動しない左右風向板が一体的に形成されている装置基板」を製造する必要があった。このため、左右風向調整装置を新規に製造する際の費用が増すという問題点があった。 The left and right airflow direction adjusting device disclosed in Patent Document 1 is a left side that forms a blowout port even when a plurality of left and right rotation plates are largely rotated leftward (or rightward) to execute oblique blowing during cooling operation. Since the wind flow in the range close to the (or right) side wall is guided in the front direction by the left and right wind direction plates that do not rotate, the collision of the cooling air with the left (or right) side wall is suppressed. For this reason, the dew condensation to the side wall which forms the blower outlet at the time of air_conditionaing | cooling operation can be suppressed.
However, since the left and right wind direction adjusting device disclosed in Patent Document 1 is integrally formed with a non-rotating left and right wind direction plate on a device substrate that rotatably supports a plurality of left and right rotating plates. There was a problem.
In other words, depending on the type and capacity (capacity) of the air conditioner or the type of the indoor unit, the form of dew condensation on the side wall forming the air outlet differs, so the model and capacity (capacity) of the air conditioner Alternatively, the optimal direction and optimal shape (size, etc.) of the left and right wind direction plates that do not rotate differ depending on the type of the indoor unit. Therefore, although the shape of the device substrate itself is the same, there are many types of “does not rotate”, only the shape and direction of the non-rotating left and right wind direction plates that are small in size compared to the device substrate are different. It was necessary to manufacture a device substrate in which left and right wind direction plates were integrally formed. For this reason, there has been a problem that the cost for newly manufacturing the left and right wind direction adjusting device increases.

この発明は、上記のような課題を解決するためになされたもので、新規に製造する際の費用を低減することができる左右風向調整装置、および該左右風向調整装置を有する空気調和機の室内機を得るものである。 The present invention has been made in order to solve the above-described problems, and is capable of reducing the cost of newly manufacturing a left / right air direction adjusting device, and an air conditioner room having the left / right air direction adjusting device. You will get a chance.

本発明に係る左右風向調整装置は、空気調和機の室内機における風路の一部を形成する長方形の板材であって、短辺側の端部に近い位置に形成された取付用凹部を具備する装置基板と、前記取付用凹部に挿入される取付用ボス部および前記取付用ボス部に一体的に形成された板状のフラップを具備する左右風向板と、を有し、前記取付用凹部に前記取付用ボス部が取り付けられていることを特徴とする。 The left and right airflow direction adjusting device according to the present invention is a rectangular plate member that forms a part of an air passage in an indoor unit of an air conditioner, and includes a mounting recess formed at a position close to the end portion on the short side. A mounting board to be inserted into the mounting recess, and a left and right wind direction plate having a plate-like flap formed integrally with the mounting boss, and the mounting recess. The mounting boss part is attached to the base plate.

本発明に係る左右風向調整装置は、装置基板と左右風向板とが別体として形成されるから、空気調和機の機種や容量（能力）あるいは室内機の形式等に応じて、左右固定板のみを最適な形状（大きさ等）に形成し、最適な方向に取り付けることが可能になる。よって、装置基板の共通化を進めることができる。すなわち、「小物」である左右固定板については、要望に応じてそれぞれの形状に対応した多種類を製造し、「大物」である装置基板については、共通化した単一形状の少種類を製造するだけで済むため、風向調整装置を新規に製造する際の費用を圧縮することができる。 In the left / right airflow direction adjusting device according to the present invention, the device substrate and the left / right airflow direction plate are formed as separate bodies, so that only the right and left fixed plates are used depending on the type and capacity (capability) of the air conditioner or the type of the indoor unit Can be formed in an optimal shape (size, etc.) and attached in an optimal direction. Therefore, the device substrate can be shared. In other words, for left and right fixed plates that are “small items”, various types corresponding to each shape are manufactured upon request, and for device substrates that are “large items”, a small number of common single shapes are manufactured. Therefore, the cost for newly manufacturing the wind direction adjusting device can be reduced.

That is, when the boss first portion 221 and the boss second portion 222 are respectively inserted into the mounting circular portion 121 and the mounting rectangular portion 122, the back flange 222c slides on the sandwiching slope 122c and the distance between the sandwiching slopes 122c. Then, it is removed from the sandwiching slope 122c and is sandwiched (locked) by the sandwiching projection 122d so that it cannot be pulled out and cannot rotate.

以上のように、左右風向板２００の取付用ボス部２２０は、装置基板１００の取付用凹部１２０に侵入して、ネジ３００と、挟み突起１２２ｄによる奥フランジ２２２ｃの挟み付け（係止）とによって、抜け出し不能且つ回転不能に確実に取り付けられるから、フラップ２１０のビビリ振動が防止される。
なお、すなわち、ボス第１部分２２１およびボス第２部分２２２を取付用円部分１２１および取付用矩形部分１２２にそれぞれ侵入する際、奥フランジ２２２ｃ自体が幅が狭くなるように弾性変形しながら挟み斜面１２２ｃに摺動し、やがて、挟み斜面１２２ｃから外れて、挟み突起１２２ｄによって抜け出し不能および回転不能に挟まれる（係止する）ようにしてもよい。 As described above, the mounting boss portion 220 of the right and left wind direction plate 200 enters the mounting recess 120 of the apparatus substrate 100, and is sandwiched (locked) by the screw 300 and the back flange 222c by the sandwiching protrusion 122d. Since it is securely attached so that it cannot be pulled out and cannot be rotated, chatter vibration of the flap 210 is prevented.
That is, when the boss first part 221 and the boss second part 222 are respectively inserted into the mounting circular part 121 and the mounting rectangular part 122, the back flange 222c itself is elastically deformed so that the width is narrowed, and the slope is sandwiched. It may slide to 122c and eventually come off from the sandwiching slope 122c and be sandwiched (locked) by the sandwiching projection 122d so that it cannot be pulled out and cannot rotate.

（フラップの変形例）
次に、図７〜図９に基づいて、左右風向板の変形例を説明する。なお、前記した左右風向板２００と同じ部分にはこれと同じ符号を付し、一部の説明を省略する。
図７において、左右風向板２００ｘは、左右風向板２００におけるフラップ２１０の面積を大きくしたものである。このとき、フラップ２１０の形状が台形でない歪な四角形になっているが、本発明はかかる形状を限定するものではない。そして、取付用ボス部２２０は、機種等に応じて、フラップ２１０の面積を変更しても、取付用凹部１２０に取り付けることができる。 (Flap variation)
Next, modified examples of the left and right wind direction plates will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to this same part as above-mentioned left-right wind direction board 200, and a part of description is abbreviate | omitted.

The mounting boss 220 can be attached to the mounting recess 120 even if the area of the flap 210 is changed according to the model or the like.

図８において、左右風向板２００ｙは、フラップ２１０と取付用ボス部２２０とが同一面内になく、フラップ２１０の方向と取付用ボス部２２０との方向が所定の角度だけ折れ曲がっている。なお、取付用ボス部２２０は左右風向板２００における取付用ボス部２２０に同じであるから、機種等に応じて、フラップ２１０の姿勢（風の案内方向）を変更しても、取付用凹部１２０に取り付けることができる。 In FIG. 8, the left and right wind direction plates 200y do not have the flap 210 and the mounting boss 220 in the same plane, and the direction of the flap 210 and the direction of the mounting boss 220 are bent by a predetermined angle. The mounting boss portion 220 is the same as the mounting boss portion 220 in the left and right wind direction plate 200. Therefore, even if the posture of the flap 210 (wind guide direction) is changed according to the model or the like, the mounting recess portion 120 is used. Can be attached to.

図９において、左右風向板２００ｚは、フラップ２１０を湾曲した断面略円弧状にしたものである。このとき、取付用ボス部２２０は左右風向板２００における取付用ボス部２２０に同じであるから、機種等に応じて、フラップ２１０の形状（風の案内要領）を変更しても、取付用凹部１２０に取り付けることができる。なお、本発明はフラップの形状を湾曲したものに限定するものではなく、例えば、断面を翼形状にしてもよい。 In FIG. 9, the left and right wind direction plates 200z are formed by making the flap 210 into a curved section having a substantially circular arc shape. At this time, since the mounting boss portion 220 is the same as the mounting boss portion 220 in the left and right wind direction plate 200, the mounting recess portion can be changed even if the shape of the flap 210 (wind guide procedure) is changed according to the model or the like. 120 can be attached. In the present invention, the shape of the flap is not limited to the curved shape. For example, the cross section may be a wing shape.

In FIG. 10A, the left / right airflow direction adjusting device 2000 includes an apparatus substrate 100 and a left / right airflow direction plate 400. In the first embodiment, the left and right wind direction plates 200 are fixed to the device substrate 100 using the screws 300. In the second embodiment, the left and right wind direction plates 400 are fixed to the device substrate 100 without using the screws 300. It is. Hereinafter, differences from the first embodiment will be described.

（左右風向板）
左右風向板４００は、板状のフラップ２１０と、フラップ２１０と一体的に形成された取付用ボス部４２０とを具備する。そして、取付用ボス部４２０は、取付用円部分１２１に侵入するボス第１部分４２１と、取付用矩形部分１２２に侵入するボス第２部分２２２とを具備する。
ボス第１部分４２１は、円盤状の手前フランジ４２１ａおよび奥フランジ４２１ｃと、手前フランジ４２１ａと奥フランジ４２１ｃとを連結する円柱部４２１ｂと、奥フランジ４２１ｃに形成され、円柱部４２１ｂとは反対方向に突出する固定用突起４２１ｄとを具備している。 (Left and right wind direction plate)
The right and left wind direction plate 400 includes a plate-shaped flap 210 and a mounting boss portion 420 formed integrally with the flap 210. The mounting boss portion 420 includes a boss first portion 421 that enters the mounting circle portion 121 and a boss second portion 222 that enters the mounting rectangular portion 122.
The boss first portion 421 is formed in a disk-like front flange 421a and a back flange 421c, a cylindrical portion 421b that connects the front flange 421a and the back flange 421c, and the back flange 421c, and in a direction opposite to the cylindrical portion 421b. And a fixing protrusion 421d that protrudes.

（左右風向板の取付用凹部への取り付け）
図１０の（ａ）において、取付用ボス部４２０を形成するボス第１部分４２１が、取付用凹部１２０を形成する取付用円部分１２１に侵入している（なお、ボス第２部分２２２が、取付用矩形部分１２２に侵入しているが、図示しない。図６の（ｂ）参照）。
このとき、手前フランジ４２１ａは円形孔１２１ａを塞ぎ、奥フランジ４２１ｃは底部１２１ｃ（円筒部１２１ｂの内側の面）に当接している。そして、固定用突起４２１ｄが貫通孔１２１ｄを貫通して、底部１２１ｃ（円筒部１２１ｂの外側の面）から突出している。 (Mounting the left and right wind direction plates in the mounting recess)
10A, the boss first portion 421 that forms the mounting boss portion 420 has entered the mounting circle portion 121 that forms the mounting recess 120 (note that the boss second portion 222 is Although it has penetrated into the mounting rectangular portion 122, it is not illustrated (see FIG. 6B).
At this time, the front flange 421a closes the circular hole 121a, and the back flange 421c is in contact with the bottom 121c (the inner surface of the cylindrical portion 121b). The fixing protrusion 421d penetrates the through hole 121d and protrudes from the bottom 121c (the outer surface of the cylindrical portion 121b).

図１０の（ｂ）において、固定用突起４２１ｄの底部１２１ｃから突出した範囲が、加熱によって塑性変形され、外径が拡大され、突起拡大部４２１ｅが形成されている。したがって、左右風向調整装置２０００は、ネジ３００を用いることなく、また、取付用ボス部４２０に雌ネジを形成することなく、左右風向板４００を取付用凹部１２０に抜け出し不能に固定することが出来るから、製造コストを低減することができる。
なお、以上は、固定用突起４２１ｄが断面円形の貫通孔１２１ｄに貫通するものであるが、本発明はこれに限定するものではなく、固定用突起４２１ｄおよび貫通孔１２１ｄを断面楕円または断面矩形状にして、左右風向板４００を取付用凹部１２０に抜け出し不能且つ回転不能に固定してもよい。このとき、ボス第１部分４２１および取付用円部分１２１を、それぞれ断面楕円または断面矩形状にして、ボス第２部分２２２および取付用矩形部分１２２の形成を省略してもよい。 In FIG. 10B, the range protruding from the bottom 121c of the fixing projection 421d is plastically deformed by heating, the outer diameter is enlarged, and the projection enlarged portion 421e is formed. Therefore, the left / right airflow direction adjusting device 2000 can fix the left / right airflow direction plate 400 to the mounting recess 120 so as not to be pulled out without using the screw 300 and without forming a female screw on the mounting boss 420. Therefore, the manufacturing cost can be reduced.

［実施の形態３］
図１１〜図１４は本発明の実施の形態３に係る空気調和機の室内機を説明するものであって、図１１は断面図、図１２は一部（回動左右風向板）を抜き出して示す斜視図、図１３は一部（吹出口の周囲）を抜き出して示す正面図、図１４は一部（吹出口の周囲）を抜き出して拡大して示す斜視図である。なお、実施の形態１と同じ部分または相当する部分には同じ符号を付し、一部の説明を省略する。 [Embodiment 3]
11 to 14 illustrate an indoor unit of an air conditioner according to Embodiment 3 of the present invention. FIG. 11 is a cross-sectional view, and FIG. 12 is a partial (rotating left and right wind direction plate) extracted. FIG. 13 is a front view showing a part (around the air outlet) extracted, and FIG. 14 is an enlarged perspective view showing a part (around the air outlet). In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and one part description is abbreviate | omitted.

図１１において、空気調和機の室内機３０００は、吸込口３および吹出口７を具備する筐体１と、筐体１内に配置され、吸込口３から吹出口７に至る風路６を形成する送風機５と、風路６内に設置され、冷凍サイクル（図示しない）の一部を形成する熱交換器４と、実施の形態１において説明した左右風向調整装置１０００（正確には、左側に設置された左右風向調整装置１０００Ｌと、右側に設置された左右風向調整装置１０００Ｒ）とを有する。
前面パネル２に近い位置で熱交換器４の下方に、ドレン受け８が設けられ、ドレン受け８の下面側に、装置基板１００が設置されている。したがって、装置基板１００の平面部１１０は、調和空気の流れを案内しているから、風路６の一部を形成している。
そして、吹出口７には上下風向板９ａ、９ｂが水平方向の回動軸（図示しない）を中心にして回動自在に設置され、装置基板１００には、装置基板１００に垂直な回動軸（図示しない）を中心に回動する（所定の回動範囲内を回動して停止、または往復回動を繰り返す）回動左右風向板５００が回動自在に取り付けられている。 In FIG. 11, an indoor unit 3000 of an air conditioner forms a housing 1 having a suction port 3 and an air outlet 7 and an air passage 6 that is arranged in the housing 1 and extends from the air inlet 3 to the air outlet 7. And the heat exchanger 4 that is installed in the air passage 6 and forms a part of a refrigeration cycle (not shown), and the left and right airflow direction adjusting device 1000 described in the first embodiment (more precisely, on the left side) A left / right airflow direction adjusting device 1000L and a left / right airflow direction adjusting device 1000R) installed on the right side.
A drain receiver 8 is provided below the heat exchanger 4 at a position close to the front panel 2, and an apparatus substrate 100 is installed on the lower surface side of the drain receiver 8. Therefore, the flat portion 110 of the device substrate 100 forms a part of the air path 6 because it guides the flow of conditioned air.
The upper and lower airflow direction plates 9 a and 9 b are installed at the blowout port 7 so as to be rotatable about a horizontal rotation axis (not shown), and the apparatus substrate 100 has a rotation axis perpendicular to the apparatus substrate 100. Rotating left and right wind direction plates 500 that rotate about (not shown) (rotate within a predetermined rotation range and stop or repeat reciprocating rotation) are rotatably attached.

図１２において、回動左右風向板５００は、複数の板状の回動フラップ５１０と、回動フラップ５１０と一体的に形成された回動ボス部５２０とを具備し、回動ボス部５２０には回動腕部５２１および回動フランジ５２２が一体的に形成されている。
そして、複数の回動腕部５２１が、回動連結棒５３０によって連結され、回動連結棒５３０は、回動モーター５４０によって、並進される。
このとき、回動フランジ５２２が装置基板１００に形成された回動保持部１３０（図２および図３参照）に回動自在に保持され、複数の回動腕部５２１と回動連結棒５３０との接続位置が前記回動軸から離れているため、回動連結棒５３０の並進によって回動フラップ５１０は回動する。 In FIG. 12, the turning left and right wind direction plate 500 includes a plurality of plate-like turning flaps 510 and a turning boss portion 520 formed integrally with the turning flap 510. The rotating arm 521 and the rotating flange 522 are integrally formed.
A plurality of rotating arm portions 521 are connected by a rotating connecting rod 530, and the rotating connecting rod 530 is translated by a rotating motor 540.
At this time, the rotation flange 522 is rotatably held by a rotation holding portion 130 (see FIGS. 2 and 3) formed on the apparatus substrate 100, and a plurality of rotation arm portions 521, a rotation connecting rod 530, and the like. Since the connecting position is away from the rotation shaft, the rotation flap 510 is rotated by the translation of the rotation connecting rod 530.

図１３および図１４において、空気調和機の室内機３０００は、風路６の吹出口７に近い位置の左側に左右風向調整装置１０００Ｌが設置され、風路６の吹出口７に近い位置の右側に左右風向調整装置１０００Ｒが設置されている。そして、左側の左右風向調整装置１０００Ｌの装置基板１００Ｌには左右風向板２００Ｌおよび回動左右風向板５００Ｌが取り付けられ、右側の左右風向調整装置１０００Ｒの装置基板１００Ｒには左右風向板２００Ｒおよび回動左右風向板５００Ｒが取り付けられている。
このとき、左側の左右風向板２００Ｌのフラップ２１０Ｌは、調和空気を右方向に案内し、右側の左右風向板２００Ｒのフラップ２１０Ｒは、調和空気を左方向に案内している。すなわち、左側のフラップ２１０Ｌは、吹き出された調和空気の左側の風路側壁７Ｌへの衝突を防止し、右側のフラップ２１０Ｒは、吹き出された調和空気の右側の風路側壁７Ｒへの衝突を防止しているから、冷房運転の際、風路側壁７Ｌおよび風路側壁７Ｒへの着露が防止される。
なお、図１３および図１４では、回動左右風向板５００Ｌおよび回動左右風向板５００Ｒの回動フラップ５１０Ｌおよび回動フラップ５１０Ｒは、「正面吹き」の状態であるが、これらは回動するものであるから、例えば、回動フラップ５１０Ｌが左方向に「斜め吹き」の状態になって、調和空気を左方向に案内した場合には、左側のフラップ２１０Ｌによる風路側壁７Ｌへの着露防止効果が顕著になる。 In FIG. 13 and FIG. 14, the indoor unit 3000 of the air conditioner has a left / right airflow direction adjusting device 1000 </ b> L installed on the left side of the air passage 6 near the air outlet 7, and the right side of the air passage 6 near the air outlet 7. The left and right airflow direction adjusting device 1000R is installed. The left and right wind direction adjusting device 1000L has a left and right wind direction plate 200L and a rotating left and right wind direction plate 500L attached to the device substrate 100L, and the right and left wind direction adjusting device 1000R has a left and right wind direction plate 200R and a turning direction. Left and right wind direction plates 500R are attached.
At this time, the flap 210L of the left and right wind direction plates 200L on the left side guides conditioned air in the right direction, and the flap 210R on the right and left side wind direction plates 200R guides the conditioned air in the left direction. That is, the left flap 210L prevents the blown conditioned air from colliding with the left air passage side wall 7L, and the right flap 210R prevents the blown conditioned air from colliding with the right air passage side wall 7R. Therefore, during the cooling operation, dew condensation on the air passage side wall 7L and the air passage side wall 7R is prevented.
In FIG. 13 and FIG. 14, the turning flap 510L and the turning flap 510R of the turning left and right wind direction plate 500L and the turning left and right wind direction plate 500R are in a “front blowing” state, but these are rotating. Therefore, for example, when the rotating flap 510L is in the “slanting blow” state in the left direction and the conditioned air is guided in the left direction, the left flap 210L prevents dew condensation on the air passage side wall 7L. The effect becomes remarkable.
