(2)空気調和装置の空調運転動作  (2) Air conditioning operation of the air conditioner
次に、空気調和装置 1の空調運転動作について、図 1及び図 2を用いて説明する。 運転を開始すると、ファンモータ 51が駆動されて、送風ファン 5の羽根車 52が回転 する。また、ファンモータ 51の駆動とともに、熱交^^ 6内には、室外ユニット(図示せ ず)から冷媒が供給される。ここで、熱交換器 6は、冷房運転時には蒸発器として、暖 房運転時には凝縮器として作用する。そして、羽根車 52の回転に伴って、空調室内 の空気は、吸入流路 2aを通じて化粧パネル 4の吸入口 41からケーシング本体 3内に 吸入される。この吸入された空気は、羽根車 52によって外周側に吹き出されて熱交 6に達し、熱交 6において冷却又は加熱された後、吹出流路 2bを通じて化 粧パネル 4の吹出口 42a〜42dから空調室内に向かって吹き出される。このようにし て、空調室内の冷房又は暖房が行われる。  Next, the air conditioning operation of the air conditioner 1 will be described with reference to FIGS. When the operation is started, the fan motor 51 is driven, and the impeller 52 of the blower fan 5 rotates.

[0021] (4)フィルタの清掃動作 [0021] (4) Filter cleaning operation
次に、空気調和装置 1のフィルタ 44の清掃動作について、図 4〜図 8を用いて説明 する。  Next, the cleaning operation of the filter 44 of the air conditioner 1 will be described with reference to FIGS.
空気調和装置 1の空調運転を所定時間行った後、自動的に又は手動操作により、 フィルタ 44のモータ(図示せず)を駆動し、スプロケット 47を回転させて濾過部材 46 を循環移動させる。すると、濾過部材 46が清掃機構 9の通路 92を通過し、この通過 の際に、接触部 93によってフィルタ 44の毛状部材 46cに捕集された塵埃が払い落と されて、ダストボックス 11内に溜まる。すなわち、清掃機構 9によりフィルタ 44が捕集 した塵埃をフィルタ 44から除去し、ダストボックス 11に清掃機構 9によって除去された 塵埃を溜めることができる。  After the air conditioning operation of the air conditioner 1 is performed for a predetermined time, a motor (not shown) of the filter 44 is driven automatically or manually, and the sprocket 47 is rotated to circulate the filter member 46. Then, the filtering member 46 passes through the passage 92 of the cleaning mechanism 9, and during this passage, the dust collected by the hair-like member 46 c of the filter 44 is removed by the contact portion 93 and collected in the dust box 11. . That is, the dust collected by the filter 44 by the cleaning mechanism 9 can be removed from the filter 44, and the dust removed by the cleaning mechanism 9 can be stored in the dust box 11.
[0022] 次に、ダストボックス 11に塵埃が溜まったら、掃除機のノズル 20をノズル差込口 13 に下方力も差し込むことによって、開閉蓋 14を掃除機のノズル 20の先端によって上 方に押して開き、掃除機を運転してダストボックス 11内に溜まった塵埃をダストボック ス 11内から掃除機に吸引する。このとき、内弁 16が掃除機の吸引力によって弾性変 形するため(図 8参照)、ダストボックス 11内に溜まった塵埃がダストボックス 11内から 速やかに排出されて掃除機に吸引される。また、このとき、掃除機の吸引力によって ダストボックス 11内の空気が排出されてダストボックス 11の圧力が低くなる傾向にな る力 本実施形態の空気調和装置 1では、ダストボックス 11の第 2壁部 17に空気孔 1 7aが設けられているため、掃除機による吸引作業中に、ダストボックス 11内にケーシ ング 2の外部から空気が取り込まれることとなり、過度にダストボックス内の圧力が極 度に低くなつて塵埃が掃除機の吸引されにくくなるのを防ぐことができるようになって いる。 [0022] Next, when dust accumulates in the dust box 11, the opening / closing lid 14 is pushed upward by the tip of the nozzle 20 of the vacuum cleaner by inserting the downward force of the nozzle 20 of the vacuum cleaner into the nozzle insertion port 13, and opens. Operate the vacuum cleaner and suck the dust accumulated in the dust box 11 from the dust box 11 into the vacuum cleaner. At this time, since the inner valve 16 is elastically deformed by the suction force of the cleaner (see FIG. 8), the dust accumulated in the dust box 11 is quickly discharged from the dust box 11 and sucked into the cleaner. Further, at this time, the force that tends to lower the pressure of the dust box 11 due to the air in the dust box 11 being discharged by the suction force of the vacuum cleaner. In the air conditioner 1 of the present embodiment, the second wall portion 17 of the dust box 11 The air hole 17a is provided in the dust box 11 during suction work with a vacuum cleaner. Air is taken in from the outside of the ring 2, and the pressure in the dust box becomes excessively low, so that it is possible to prevent dust from becoming difficult to be sucked by the vacuum cleaner.
[0023] そして、ダストボックス 11内に溜まった塵埃をダストボックス 11内から排出して掃除 機に吸引する作業が終了したら、掃除機の運転を停止し、掃除機のノズル 20をノズ ル差込口 13から抜き出す。これにより、掃除機の吸引力が内弁 16に作用しない状態 になるため、内弁 16が閉じられる。また、掃除機のノズル 20によって開閉蓋 14が上 方に押し上げる力が作用しない状態になるため、自重により開閉蓋 14が閉じられる。  [0023] Then, when the dust accumulated in the dust box 11 is discharged from the dust box 11 and sucked into the cleaner, the operation of the cleaner is stopped, and the nozzle 20 of the cleaner is inserted into the nozzle inlet 13 Extract from. As a result, the suction force of the vacuum cleaner does not act on the inner valve 16, so the inner valve 16 is closed. Moreover, since the force which pushes up the opening / closing lid 14 by the nozzle 20 of the vacuum cleaner does not act, the opening / closing lid 14 is closed by its own weight.

上述の実施形態及び変形例 1にかかる空気調和装置 1では、ダストボックス 11の上 面を構成する第 2壁部 17にケーシング 2の外側に連通する複数の空気孔 17aが形 成されている力 図 10又は図 11に示されるように、第 2壁部 17に複数の空気孔 17a を形成することに代えて、又は、第 2壁部 17に複数の空気孔 17aを形成するととも〖こ 、ダストボックス 11の側面を構成する第 3壁部 18にケーシング 2の外側に連通する複 数の空気孔 18aを形成するようにしてもよい。ここで、複数の空気孔 18aは、第 1壁部 12と第 2壁部 17との中間位置力も第 2壁部 17側の位置 (すなわち、第 2壁部 17の内 面から下方に第 1壁部 12の内面と第 2壁部 17の内面との距離 hの半分までの位置) に形成されている。また、これらの空気孔 18aは、上述の実施形態及び変形例 1と同 様、直径 5mm以下の略円形である。 In the air conditioner 1 according to the above-described embodiment and Modification 1, the force is such that the second wall portion 17 constituting the upper surface of the dust box 11 has a plurality of air holes 17a communicating with the outside of the casing 2. As shown in FIG. 10 or FIG. 11, instead of forming a plurality of air holes 17a in the second wall portion 17 or forming a plurality of air holes 17a in the second wall portion 17, the dust box A plurality of air holes 18 a communicating with the outside of the casing 2 may be formed in the third wall portion 18 constituting the side surface of 11. Here, the plurality of air holes 18a have an intermediate position force between the first wall portion 12 and the second wall portion 17 at the position on the second wall portion 17 side (that is, the inner wall of the second wall portion 17). The first wall portion 12 and the second wall portion 17 are formed so as to be half the distance h from the inner surface of the first wall portion 12 to the lower surface. These air holes 18a are substantially circular with a diameter of 5 mm or less, as in the above-described embodiment and Modification 1.
[0029] 本変形例に力かる空気調和装置 1では、ノズル差込口 13に面する第 1壁部 12に接 する第 3壁部 18に、複数の空気孔 18aが形成されており、掃除機のノズル 20をノズ ル差込口 13に差し込んでダストボックス 11内から塵埃を掃除機に吸引して排出する 際に、空気孔 18aを通じてダストボックス 11の外部から空気を取り入れることができる ようになっているため、ダストボックス 11内の圧力が極度に低くなり、塵埃が掃除機の 吸引されに《なるのを防ぐことができる。し力も、空気孔 18aは、第 1壁部 12と第 2壁 部 17との中間位置から第 2壁部 17側の位置に形成されて!ヽるため、掃除機のノズル 20をノズル差込口 13に差し込んでダストボックス 11内力ゝら塵埃を掃除機に吸引して 排出する際に、ダストボックス 11内に溜められた塵埃によってダストボックス 11の外 部から空気を取り入れる動作が阻害されにくくなる。  [0029] In the air conditioner 1 that is effective in the present modification, a plurality of air holes 18a are formed in the third wall portion 18 in contact with the first wall portion 12 facing the nozzle insertion port 13, and cleaning is performed. When the machine nozzle 20 is inserted into the nozzle insertion port 13 and dust is sucked into and discharged from the dust box 11, the air can be introduced from the outside of the dust box 11 through the air hole 18a. Therefore, the pressure in the dust box 11 becomes extremely low, and dust can be prevented from being sucked by the vacuum cleaner. Since the air hole 18a is formed from the intermediate position between the first wall portion 12 and the second wall portion 17 to the position on the second wall portion 17 side, the nozzle 20 of the vacuum cleaner is inserted into the nozzle. When the dust inside the dust box 11 is sucked into the vacuum cleaner 13 and sucked out by the vacuum cleaner, the dust collected in the dust box 11 is less likely to hinder the operation of taking air from the outside of the dust box 11.

上述の実施形態及び変形例 1、 2にかかる空気調和装置 1では、ダストボックス 11 に空気孔 17a、 18aを形成し、ダストボックス 11がケーシング 2の外側に連通させるこ とによって、掃除機のノズル 20をノズル差込口 13に差し込んでダストボックス 11内か ら塵埃を掃除機に吸引して排出する際に、ダストボックス 11内の圧力が極度に低くな り、塵埃が掃除機の吸引されにくくなるのを防ぐようにしているが、図 12及び図 13に 示されるように、吸入流路 2aに面する位置に複数の空気孔 19aが形成された連通部 19をケーシング 2 (具体的には、化粧パネル 4)に設け、この連通部 19をダストボック ス 11の第 3壁部 18に形成された開口 18bの位置に接続することによって、吸入流路 2aに連通させるようにしてもよい。ここで、連通部 19は、外周側の一端がダストボック ス 11の第 3壁部 18に接続されるとともに内周側の他端が化粧パネル 4の角部から内 周側に向力つて延びる筒状の部材である。そして、連通部 19の他端に形成された複 数の空気孔 19aは、吸入流路 2aのうちフィルタ 44と吸入グリル 43との間の部分に連 通している。また、これらの空気孔 19aは、上述の実施形態及び変形例 1、 2と同様、 直径 5mm以下の略円形である。 In the air conditioner 1 according to the above-described embodiment and Modifications 1 and 2, the air holes 17a and 18a are formed in the dust box 11, and the dust box 11 is communicated with the outside of the casing 2, whereby the nozzle 20 of the cleaner is made to communicate. When dust is sucked into and discharged from the dust box 11 by inserting it into the nozzle insertion port 13, the pressure inside the dust box 11 becomes extremely low, preventing dust from becoming difficult to be sucked into the vacuum cleaner. However, as shown in FIGS. 12 and 13, the communication portion 19 having a plurality of air holes 19a formed at the position facing the suction flow path 2a is provided in the casing 2 (specifically, the decorative panel 4 And the communication part 19 may be connected to the position of the opening 18b formed in the third wall part 18 of the dust box 11 so as to communicate with the suction flow path 2a. Here, the communication part 19 is a cylinder in which one end on the outer peripheral side is connected to the third wall part 18 of the dust box 11 and the other end on the inner peripheral side extends from the corner of the decorative panel 4 toward the inner peripheral side. Shaped member. The plurality of air holes 19a formed at the other end of the communication portion 19 communicate with a portion between the filter 44 and the suction grille 43 in the suction passage 2a. Through. Further, these air holes 19a are substantially circular with a diameter of 5 mm or less, as in the above-described embodiment and Modifications 1 and 2.
[0031] 本変形例に力かる空気調和装置 1では、吸入流路 2aに面する位置に複数の空気 孔 19aが形成された連通部 19が、吸入流路 2aとダストボックス 11との間を連通するよ うに設けられており、掃除機のノズル 20をノズル差込口 13に差し込んでダストボック ス 11内から塵埃を掃除機に吸引して排出する際に、空気孔 19aを通じてダストボック ス 11の外部力 空気を取り入れることができるようになるため、ダストボックス 11内の 圧力が極度に低くなり、塵埃が掃除機の吸引されに《なるのを防ぐことができる。 しかも、これらの空気孔 19aは吸入流路 2aに連通しているため、送風ファン 5の運 転によって、ダストボックス 11内を負圧にすることができ、これにより、ダストボックス 11 内の塵埃を圧縮して、コンパクトにダストボックス 11内に溜めることができる。そして、 ダストボックス 11内の塵埃を圧縮する効果を効率よく得るためには、上述の実施形態 及び変形例 1、 2にお 、て第 2壁部 17や第 3壁部 18に形成されて!、たケ一シング 2 の外側に連通する空気孔 17a、 18aを省略することが望ましい。  [0031] In the air conditioner 1 that is effective in this modification, the communication portion 19 in which a plurality of air holes 19a are formed at a position facing the suction flow path 2a communicates between the suction flow path 2a and the dust box 11. When the vacuum cleaner nozzle 20 is inserted into the nozzle inlet 13 and dust is sucked into and discharged from the dust box 11, the external force of the dust box 11 is discharged through the air hole 19a. Since air can be taken in, the pressure in the dust box 11 becomes extremely low, and dust can be prevented from being sucked by the vacuum cleaner. Moreover, since these air holes 19a communicate with the suction flow path 2a, the inside of the dust box 11 can be made negative pressure by the operation of the blower fan 5, thereby compressing the dust in the dust box 11. And can be stored in the dust box 11 in a compact manner. In order to efficiently obtain the effect of compressing the dust in the dust box 11, it is formed on the second wall portion 17 and the third wall portion 18 in the above-described embodiment and modifications 1 and 2 !, It is desirable to omit the air holes 17a and 18a communicating with the outside of the casing 2.
[0032] また、空気孔 19aは、吸入流路 2a内のフィルタ 44の上流側の位置に連通している ため、空気孔 19aを通じてダストボックス 11内に溜められた塵埃がダストボックス 11の 外部に飛散したとしても、再度、フィルタ 44によって捕集されることになり、ケーシング 2内に吸入されてしまうことはない。  [0032] Further, since the air hole 19a communicates with a position upstream of the filter 44 in the suction flow path 2a, the dust accumulated in the dust box 11 is scattered outside the dust box 11 through the air hole 19a. However, it will be collected again by the filter 44 and will not be sucked into the casing 2.
また、図 13では、ノズル差込口 13に開閉蓋 14がー糸且だけ設けられている力 変形 例 1と同様、 2組の開閉蓋 14、 114を設けるようにしてもよい。  Further, in FIG. 13, two sets of opening / closing lids 14 and 114 may be provided in the same manner as in the first modified example in which the opening / closing lid 14 is provided only at the nozzle insertion opening 13.
(9)変形例 4  (9) Modification 4
上述の実施形態及び変形例 1〜3にかかる空気調和装置 1では、ダストボックス 11 がケーシング本体 3の平面視においてケーシング本体 3の外側で、かつ、化粧パネ ル 4の角部に配置されている力 図 14及び図 15に示されるように、化粧パネル 4の吹 出口間(具体的には、吹出口 42cと吹出口 42dとの間)に設けるようにしてもよい。ここ では、ケーシング本体 3の平面視にお!/、てダストボックス 11の最外周部がケーシング 本体 3の側板 32aに沿うように、すなわち、清掃機構 9及びダストボックス 11がケーシ ング本体 3の内側に配置されて 、る。 [0033] 本変形例に力かる空気調和装置 1では、化粧パネル 4に送風ファン 5によってケー シング本体 3内に吸入された空気を空調室内に吹き出す複数の吹出口 42a〜42dが 吸入口 41を囲むように形成されており、ダストボックス 11が吹出口間の位置に配置さ れているため、化粧パネル 4の吸入口 41や吹出口 42a〜42dとダストボックス 11とが 干渉することがない。し力も、本変形例に力かる空気調和装置 1では、ダストボックス 1 1がケーシング本体 3の平面視にお ヽてケ一シング本体 3の内側に配置されて 、るた め、フィルタ 44の近傍にダストボックス 11を配置することができる。 In the air conditioner 1 according to the above-described embodiment and Modifications 1 to 3, the force that the dust box 11 is disposed on the outside of the casing body 3 in the plan view of the casing body 3 and at the corner of the decorative panel 4 As shown in FIGS. 14 and 15, the decorative panel 4 may be provided between the air outlets (specifically, between the air outlet 42c and the air outlet 42d). Here, in a plan view of the casing body 3, the outermost peripheral part of the dust box 11 is arranged along the side plate 32 a of the casing body 3, that is, the cleaning mechanism 9 and the dust box 11 are arranged inside the casing body 3. It has been. [0033] In the air conditioner 1 that is effective in the present modification, a plurality of air outlets 42a to 42d for blowing the air sucked into the casing body 3 by the blower fan 5 onto the decorative panel 4 into the air-conditioning room Since the dust box 11 is disposed between the air outlets, the dust inlet 11 and the air outlets 42a to 42d of the decorative panel 4 and the dust box 11 do not interfere with each other. In the air conditioner 1 that is effective in this modified example, the dust box 11 is disposed inside the casing body 3 in a plan view of the casing body 3 , and is therefore close to the filter 44. A dust box 11 can be arranged.
尚、本変形例に力かる空気調和装置 1では、掃除機のノズル 20をノズル差込口 13 に差し込んでダストボックス 11内から塵埃を掃除機に吸引して排出する際に、ダスト ボックス 11の外部力 空気を取り入れることができるようにするためには、変形例 2の ように、第 3壁部 18に複数の空気孔 18aを形成するか(図 10参照)、又は、変形例 3 のように、吸入流路 2aに面する位置に複数の空気孔 19aが形成された連通部 19を 第 3壁部 18に接続する(図 12及び図 13参照)にすればよ 、。  In the air conditioner 1 that is effective in this modification, when the nozzle 20 of the vacuum cleaner is inserted into the nozzle insertion port 13 and dust is sucked into the vacuum cleaner and discharged from the dust box 11, the outside of the dust box 11 is removed. In order to be able to take in force air, a plurality of air holes 18a are formed in the third wall portion 18 as in the second modification (see FIG. 10), or as in the third modification. The communication part 19 in which a plurality of air holes 19a are formed at a position facing the suction flow path 2a is connected to the third wall part 18 (see FIGS. 12 and 13).
[0034] (10)変形例 5 [0034] (10) Modification 5
上述の変形例 4にかかる空気調和装置 1では、ダストボックス 11がケーシング本体 3 の内側で、かつ、化粧パネル 4の吹出口間(具体的には、吹出口 42cと吹出口 42dと の間)に配置されている力 さらに、ケーシング本体 3の内側に配置してもよい。この 際、送風ファン 5ダストボックス 11が、吸入流路 2a内に配置されていても、送風ファン 5に吸入される空気の流れを実質的に妨げることがな 、ようにすればよ!、。  In the air conditioner 1 according to the above-described modified example 4, the dust box 11 is located inside the casing body 3 and between the outlets of the decorative panel 4 (specifically, between the outlet 42c and the outlet 42d). Further, the arranged force may be arranged inside the casing body 3. At this time, even if the blower fan 5 dust box 11 is disposed in the suction flow path 2a, the flow of air sucked into the blower fan 5 should not be substantially hindered!
例えば、図 16及び図 17に示されるように、ダストボックス 11をケーシング本体 3の平 面視において吸入グリル 43の角部に配置するようにしてもよい。この場合、ダストボッ タス 11は吸入流路 2a内に配置されている力 清掃機構 9及びダストボックス 11がドレ ンパン 7の吸入孔 71やベルマウス 8の中心孔よりも外側に配置されるため、送風ファ ン 5に吸入される空気の流れを妨げることがなぐ実質的には、吸入口 41とダストボッ タス 11とが干渉しな 、ようになって!/、る。  For example, as shown in FIGS. 16 and 17, the dust box 11 may be disposed at the corner of the suction grill 43 in a plan view of the casing body 3. In this case, since the dust cleaning mechanism 11 and the dust box 11 are disposed outside the suction hole 71 of the drain pan 7 and the center hole of the bell mouth 8, the dust bottom 11 is disposed in the suction flow path 2a. As a result, the suction port 41 and the dust button 11 do not interfere with each other without substantially obstructing the flow of the air sucked into the air!
[0035] また、図 18及び図 19に示されるように、ダストボックス 11をケーシング本体 3の平面 視において送風ファン 5の略中央部に対向する位置に配置するようにしてもよい。こ の場合、ダストボックス 11は吸入流路 2a内に配置され、し力も、清掃機構 9及びダスト ボックス 11が、ケーシング本体 3の平面視において、ドレンパン 7の吸入孔 71やベル マウス 8の中心孔に重なるように配置されている力 清掃機構 9及びダストボックス 11 が送風ファン 5の風量の吸入流路 2aのうち略中央部に比べて風量が大きい送風ファ ン 5の外周部に対向する位置から吸入される空気の流れを妨げることがないため、実 質的には、吸入口 41とダストボックス 11とが干渉しないようになっている。 Further, as shown in FIGS. 18 and 19, the dust box 11 may be arranged at a position facing the substantially central portion of the blower fan 5 in a plan view of the casing body 3. In this case, the dust box 11 is disposed in the suction flow path 2a, and the force is also reduced by the cleaning mechanism 9 and the dust. The force is arranged so that the box 11 overlaps the suction hole 71 of the drain pan 7 and the center hole of the bell mouth 8 in a plan view of the casing body 3. Since the air flow sucked from the position facing the outer peripheral part of the blower fan 5 having a larger air volume than the substantially central part of 2a is not obstructed, the suction port 41 and the dust box 11 Is not to interfere.
し力も、本変形例に力かる空気調和装置 1では、上述の実施形態及び変形例 1、 2 のように、ダストボックス 11の第 2壁部 17に複数の空気孔 17aや第 3壁部 18に複数 の空気孔 18aを形成するだけで(図 8〜図 11参照)、これらのダストボックス 11が吸入 流路 2aに連通することになる。すなわち、変形例 3にかかる空気調和装置 1のように、 連通部 19を設けることなく、ダストボックス 11と吸入流路 2aとを連通させることができ るようになる。これにより、本変形例に力かる空気調和装置 1では、連通部 19を設ける ことなく変形例 3かかる空気調和装置 1と同様に、ダストボックス 11内の塵埃を圧縮し て、コンパクトにダストボックス 11内に溜める効果等を得ることができる。  In the air conditioner 1 which is also effective in this modification, the air holes 17a and the third wall 18 are formed in the second wall 17 of the dust box 11 as in the above-described embodiment and modifications 1 and 2. Only by forming a plurality of air holes 18a (see FIGS. 8 to 11), these dust boxes 11 communicate with the suction flow path 2a. That is, unlike the air conditioner 1 according to the modification 3, the dust box 11 and the suction flow path 2a can be communicated with each other without providing the communication portion 19. As a result, in the air conditioner 1 that is effective in the present modified example, the dust in the dust box 11 is compressed in the dust box 11 in a compact manner, similarly to the air conditioner 1 in the modified example 3 without providing the communication portion 19. The effect which accumulates can be acquired.
