Abstract
Description
この発明は空気調和機に関するもので、特に吸込グリルの形状に関するものである。 The present invention relates to an air conditioner, and particularly to the shape of a suction grill.
空気調和機の室内側ユニット1は図1に示すように、内部にフィルタ8と熱交換器4と送風ファン3と図示しない電装品箱を備え、それらを支持するベース20と、前記ベース20に冠着した前面パネル2と前記前面パネル2の前面に取り付けられた吸込グリル5でなり、上部吸込口9および前面吸込口10から吸い込まれた吸込空気を熱交換して冷気あるいは暖気とし、前記送風ファン3により吹出口11から室内に送出している。
近年の室内側ユニットは吸込グリルの表面は桟を設けないフラットな面形状にして室内のインテリアに溶け込むデザインとなり、空気は上部から吸い込む方式が主流となってきた。しかしそれだけでは桟が無いことで前面からの吸込量が不足するため前面からも空気を取り入れる必要があり、図7の空気調和機Aのようにフラットな面形状の吸込グリル5の中央に横長の凹部5aを設け、その一部を吸込口10として構成することで吸込風量を増やすと共に、フラットな面による単調なデザインにアクセント的な効果も与える空気調和機が提案されている。(特許文献1)
一方、吸込グリルは空気調和機の点検修理や内包するフィルタおよび同吸込グリルの清掃のために着脱可能で取扱い易いことが求められるが、合成樹脂で成形されたフラットな面形状の吸込グリルの中央に横長の凹部を設け、その一部を吸込口10として構成した場合は、落下等の衝撃によって吸込口用の孔から左右側面にかけて変形や亀裂が発生しやすい。そのため前記空気調和機Aは吸込グリル凹部5aを左右端まで伸ばさず、前面左右端にはフラットな面を持たせることで強度を補強させるデザインとなっている。
As shown in FIG. 1, the indoor unit 1 of the air conditioner includes a filter 8, a heat exchanger 4, a blower fan 3, and an electrical component box (not shown) inside, and a base 20 that supports them, It is composed of a front panel 2 that is attached and a suction grille 5 that is attached to the front surface of the front panel 2. The suction air sucked from the upper suction port 9 and the front suction port 10 is exchanged into cold or warm air, and the air blowing The fan 3 sends the air from the blowout port 11 into the room.
In recent years, indoor units have been designed so that the surface of the suction grille has a flat surface shape without any crosspieces and melts into the interior of the room, and the method of sucking air from the top has become the mainstream. However, since the amount of suction from the front surface is insufficient due to the absence of the crosspiece alone, it is necessary to take in air from the front surface, and a horizontally long suction grille 5 in the center of the flat surface-shaped suction grille 5 as in the air conditioner A of FIG. An air conditioner has been proposed in which a concave portion 5a is provided and a part of the concave portion 5a is configured as a suction port 10 to increase the amount of suction air and to give an accentuating effect to a monotonous design with a flat surface. (Patent Document 1)
On the other hand, the suction grill is required to be detachable and easy to handle for inspection and repair of the air conditioner, cleaning of the filter and the suction grill, but the center of the flat grill shaped suction grill formed of synthetic resin is required. When a horizontally long concave portion is provided on one side and a part thereof is configured as the suction port 10, deformation and cracks are likely to occur from the suction port hole to the left and right side surfaces due to an impact such as dropping. Therefore, the air conditioner A is designed to reinforce the strength by providing flat surfaces at the front left and right ends without extending the suction grill recess 5a to the left and right ends.
また、図8の空気調和機Bのようにフラットな吸込グリルの中央に左右端まで伸びた横長の凹部を設けたデザインもある。これは吸込グリルを上下に分断させる視覚的効果によりシャープでスッキリとした印象を与え、デザインの差別化を図ることができるが、左右端まで伸ばした場合は側面がさらに弱くなる。これを補強させるため前記空気調和機Bは吸込グリル側面のフランジの幅5gを幅広くさせている。しかし、例えばフィルタ清掃等の作業者が両腕を左右に広げて横幅が例えば約800mmある大きな吸込グリルを保持することは容易ではなく、特に前記吸込グリル側面のフランジの幅5gが幅広くなると手の中に納まりきらず、大きさと重さも増し、手から落下させることがある。(特許文献2)
また、フラットな面形状ではデザインが変化に乏しいものとなってしまいがちである。そのためデザインに特徴をつけるため例えば吸込グリル自体にブランド名やキャッチフレーズ等の印刷をすることがあるが、印刷が不良となった場合は吸込グリル1枚分が無駄になる損失を招くことになり、コストの上昇につながっていた。
In addition, a flat surface shape tends to result in poor design changes. Therefore, in order to characterize the design, for example, the brand name or catchphrase may be printed on the suction grill itself, but if the printing fails, one suction grill will be lost, It led to an increase in cost.
本願発明は、吸込グリルがフラットな面形状で中央に左右端まで伸びる横長の吸込口用の凹部を設け薄型としても、変形や破損を抑制できる空気調和機を提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner that can suppress deformation and breakage even if the suction grille has a flat surface shape and is provided with a recess for a horizontally long suction port extending to the left and right ends at the center.
前記課題を解決するために、室内側ユニットの前面側に配置され、左右側面まで伸びる凹部と同凹部の一部を吸込口とした吸込グリルを備えた空気調和機において、前記凹部の左右端に補強部を設けることで変形や破損を抑制できる。 In order to solve the above-mentioned problem, in an air conditioner provided with a suction grille that is disposed on the front side of an indoor unit and extends to the left and right side surfaces and a part of the same recess as a suction port, By providing the reinforcing portion, deformation and breakage can be suppressed.
また、前記補強部は他の凹部よりも浅く形成しているが、前記補強部を設けても表面に凹部が左右側面まで伸びるデザインに影響を与えない。 Moreover, although the said reinforcement part is formed shallower than another recessed part, even if it provides the said reinforcement part, it does not affect the design which a recessed part extends to the left-right side surface on the surface.
また、前記補強部の前面に補強部材を固着させることで、より強度を補強することができる。さらに補強部材の表面に印刷を施すことで空気調和機のデザインを変えることができ、バリエーションの幅も広がる。 Further, the strength can be further reinforced by fixing the reinforcing member to the front surface of the reinforcing portion. Furthermore, the design of the air conditioner can be changed by printing on the surface of the reinforcing member, and the range of variations is widened.
このように本願発明は、吸込グリルがフラットな面形状で中央に左右端まで伸びた横長の吸込口用の凹部を設けて薄型としても、前記凹部の左右端に補強部を設けることで変形や破損を抑制できる。それに加えて前記補強部の前面に補強部材を固着させることで、より強度を補強すると共に、前記補強部材の表面に印刷を施すことで空気調和機のデザインを変えることができ、バリエーションの幅も広がる。 Thus, even if the suction grill is provided with a reinforcing portion at the left and right ends of the recess, the suction grill has a flat surface shape and is provided with a recess for the horizontally long suction port extending to the left and right ends at the center. Damage can be suppressed. In addition to that, by reinforcing a reinforcing member on the front surface of the reinforcing part, it is possible to change the design of the air conditioner by printing on the surface of the reinforcing member as well as to reinforce the strength. spread.
以下、本願発明の実施形態を添付図面に基づいた実施例1として詳細に説明する。図1は本願発明の吸込グリルを取り付けた空気調和機の構成を示す断面図、図2は本願発明の吸込グリルを取り付けた空気調和機の斜視図、図3は本願発明の吸込グリル開蓋状態を示す側面図、図4は本願発明の吸込グリルの説明図で(A)は正面図、(B)は側面図、(C)はA−A′断面部分拡大図、(D)はB−B′断面部分拡大図、(E)はC−C′断面部分拡大図、(F)はY方向から見たD部拡大斜視図、(G)は実施例2におけるA−A′断面に対応する部分拡大図である。 Hereinafter, an embodiment of the present invention will be described in detail as Example 1 based on the accompanying drawings. FIG. 1 is a sectional view showing the structure of an air conditioner to which a suction grill of the present invention is attached, FIG. 2 is a perspective view of the air conditioner to which the suction grill of the present invention is attached, and FIG. FIG. 4 is an explanatory view of the suction grill of the present invention. FIG. 4A is a front view, FIG. 4B is a side view, FIG. 4C is a partial enlarged view of AA 'cross section, and FIG.

FIG.
本願発明による空気調和機の室内側ユニット1は、図1および図2に示すように、内部にフィルタ8と熱交換器4と送風ファン3と図示しない電装品箱を備え、それらを支持するベース20と、前記ベース20に冠着した前面パネル2と前記前面パネル2の前面に取り付けられた吸込グリル5でなり、上部吸込口9および前面吸込口10から吸い込まれた吸込空気を熱交換して冷気あるいは暖気とし、前記送風ファン3により吹出口11から室内に送出している。 As shown in FIGS. 1 and 2, an indoor unit 1 of an air conditioner according to the present invention includes a filter 8, a heat exchanger 4, a blower fan 3, and an electrical component box (not shown) inside, and a base for supporting them. 20, a front panel 2 attached to the base 20, and a suction grill 5 attached to the front surface of the front panel 2. The suction air sucked from the upper suction port 9 and the front suction port 10 is subjected to heat exchange. Cool air or warm air is sent out from the air outlet 11 into the room by the blower fan 3.
前記吸込グリル5の表面はフラットな面形状であり、前記吸込グリル5のほぼ中央にフラットな面を上下に分断する吸込グリル凹部5aが設けられている。同凹部5aは、側面視で前面側が広い台形状に落ち込み、下面に前記前面吸込口10があり空気を取り入れている。同前面吸込口10の前面視での横幅は内装する前記熱交換器4と略同幅である。 The surface of the suction grill 5 has a flat surface shape, and a suction grill recess 5a that divides the flat surface in the vertical direction is provided substantially at the center of the suction grill 5. The concave portion 5a falls into a trapezoidal shape with the front side wide when viewed from the side, and the front suction port 10 is provided on the lower surface to take in air. The width of the front suction port 10 in the front view is substantially the same as that of the heat exchanger 4 provided therein.
また、図3に示すように前記吸込グリル5は空気調和機の点検修理や内包する前記フィルタ8および同吸込グリル5の清掃のために着脱可能であり、前記吸込グリル5上端の係止軸12が前記前面パネル2の上端の支点13に軸支されている。作業者は外す場合は閉蓋状態の前記吸込グリル5をバネ機構等で図3の位置まで開け、前記吸込グリル5の左右端を掴んで上に持ち上げ、前記係止軸12を前記支点13から外す。反対に前記吸込グリル5を取り付ける場合は、前記吸込グリル5の左右端を掴み前記係止軸12を前記支点13に合わせ、前記吸込グリル5を上から下に降ろし、前記前面パネル2のバネ機構等に係止させる。 Further, as shown in FIG. 3, the suction grill 5 is detachable for inspection and repair of the air conditioner and cleaning of the filter 8 and the suction grill 5 included therein, and a locking shaft 12 at the upper end of the suction grill 5. Is pivotally supported by a fulcrum 13 at the upper end of the front panel 2. When the operator removes the suction grille 5 in the closed state to a position shown in FIG. 3 by a spring mechanism or the like, grasps the left and right ends of the suction grille 5 and lifts them upward, and lifts the locking shaft 12 from the fulcrum 13. remove. On the contrary, when the suction grill 5 is attached, the left and right ends of the suction grill 5 are gripped, the locking shaft 12 is aligned with the fulcrum 13, the suction grill 5 is lowered from the top, and the spring mechanism of the front panel 2 is placed. And so on.
その際、前記吸込グリル5は横幅が約800mmあるため、作業者が両腕を左右に広げて一連の作業をすることは容易ではない。そのため前記吸込グリル5の厚さは手の中に容易に持てる厚さが望ましく、前記吸込グリル5側面のフランジの幅5gは10mm以下となっている。しかし、合成樹脂で加工されたフラットな面形状で薄型の吸込グリルの中央にフラットな面を上下に分断する凹部5aを設けたため、前記凹部5aの部分が肉薄となるため作業中に変形や破損が発生しやすくなる。 At that time, since the suction grill 5 has a width of about 800 mm, it is not easy for an operator to perform a series of operations with both arms extended to the left and right. Therefore, the thickness of the suction grill 5 is preferably a thickness that can be easily held in the hand, and the width 5g of the flange on the side surface of the suction grill 5 is 10 mm or less. However, since the concave portion 5a that divides the flat surface up and down is provided in the center of the thin suction grille with a flat surface shape processed with synthetic resin, the concave portion 5a becomes thin, so that deformation or breakage occurs during work. Is likely to occur.
これを解決するため本願発明は前記吸込グリル凹部5aの左右端に補強部5bを設ける。前記補強部5bは図4(D)および(E)のように他の凹部5aよりも浅くなっており、前記補強部5bの幅は図4(F)のように前記吸込グリル凹部5aの中で前記前面吸込口10以外の部分にあたる。前記補強部5bの立上げ部5cは図4(E)のように傾斜させることで箱状のイメージを緩和している。また実施例2として図4(G)のように立上げ部5cをなだらかなスロープにすることで前記吸込グリル凹部5aと一体感を持たせることもできる。これにより前記吸込グリル5の側面が補強され、変形や破損を抑制できる充分な強度を確保することができる。 In order to solve this problem, the present invention provides reinforcing portions 5b at the left and right ends of the suction grill recess 5a. The reinforcing portion 5b is shallower than the other concave portions 5a as shown in FIGS. 4D and 4E, and the width of the reinforcing portion 5b is within the suction grill concave portion 5a as shown in FIG. 4F. It corresponds to a portion other than the front suction port 10. The rising portion 5c of the reinforcing portion 5b is inclined as shown in FIG. 4E to relax the box-like image. Further, as the second embodiment, as shown in FIG. 4 (G), the rising portion 5c has a gentle slope, so that it can have a sense of unity with the suction grill recess 5a. As a result, the side surface of the suction grill 5 is reinforced, and sufficient strength can be secured to prevent deformation and breakage.
図5は本願発明の実施例3と実施例4を示す吸込グリルを取り付けた空気調和機の斜視図、図6(A)は実施例3における図4のC−C′断面に対応する部分拡大図、(B)は実施例4における図4のC−C′断面に対応する部分拡大図、(C)は実施例5における図4のC−C′断面に対応する部分拡大図である。 FIG. 5 is a perspective view of an air conditioner equipped with a suction grill showing Embodiments 3 and 4 of the present invention, and FIG. 6A is a partially enlarged view corresponding to the section CC ′ of FIG. 4B is a partially enlarged view corresponding to the CC ′ section of FIG. 4 in the fourth embodiment, and FIG. 4C is a partially enlarged view corresponding to the CC ′ section of FIG.
図4(A)D部付近の空気調和機の内部には電装品箱(図示せず)が配置されていることが多い。その場合は前面吸込口10の幅が電装品箱の幅の分だけ狭くなるため、例えば図5のように補強部5bの幅を前記電装品箱の幅に合わせ、前記補強部5bの表面に補強部材6を固着させることでより強度を補強することができる。さらに前記補強部材6にはブランド名やキャッチフレーズ等の印刷を施すことで、フラットで変化に乏しい空気調和機Cのデザインを変えることができ、バリエーションの幅も広がる。また従来の直接吸込グリルに印刷することで、印刷不良により吸込グリル1枚分が無駄になる損失も解消できる。 In many cases, an electrical component box (not shown) is arranged inside the air conditioner near the portion D in FIG. In this case, since the width of the front suction port 10 is reduced by the width of the electrical component box, the width of the reinforcing portion 5b is adjusted to the width of the electrical component box as shown in FIG. The strength can be further reinforced by fixing the reinforcing member 6. Furthermore, the design of the air conditioner C, which is flat and poor in change, can be changed by printing a brand name, a catchphrase, etc. on the reinforcing member 6, and the range of variations is widened. Further, by printing on the conventional direct suction grille, it is possible to eliminate the loss of one suction grille due to defective printing.
その際前記補強部材6を固着させる構成として、実施例3として図6(A)のように合成樹脂の成形品の表面にシルク印刷を施し、裏面に係止用爪6aを二本突設した前記補強部材6を、前記補強部5bの表面に設けた係止用孔5dに前記係止用爪6aで係止させる。 At that time, as a configuration for fixing the reinforcing member 6, silk printing was performed on the surface of the synthetic resin molded product as Example 3 as shown in FIG. 6A, and two locking claws 6 a were provided on the back surface. The reinforcing member 6 is locked by the locking claw 6a in a locking hole 5d provided on the surface of the reinforcing portion 5b.
または実施例4として図6(B)のように合成樹脂の成形品の表面にシルク印刷を施すか、または板金の加工品の表面にオフセット印刷を施した前記補強部材6を、両面テープ等の接着剤7で前記補強部5bの表面に接着させる。 Alternatively, as Example 4, the reinforcing member 6 that is subjected to silk printing on the surface of the synthetic resin molding as shown in FIG. 6B or offset printing on the surface of the processed sheet metal product is used as a double-sided tape or the like. The adhesive 7 is adhered to the surface of the reinforcing portion 5b.
その場合は実施例5として図6(C)のように前記補強部5bの表面に落ち込みを設け、前記補強部材6を前記補強部5bの落ち込みの形に添わせた形状にして両面テープ等の接着剤7で前記補強部5bの落ち込みの中に接着させても良い。 In that case, as shown in FIG. 6C, as Example 5, a depression is provided on the surface of the reinforcing part 5b, and the reinforcing member 6 is shaped to follow the shape of the depression of the reinforcing part 5b. The adhesive 7 may be adhered to the dent of the reinforcing portion 5b.
