不通過熱交換器6而未被調整溫濕度之空氣可被供給至靜 電霧化裝置18。如此一來’可有效防止於冷氣中靜電霧化 裝置30之帕耳帖元件36整體產生結露而能提昇安全性。 又，於暖氣時可確實產生靜電霧。 15 200928244 旁通流路22由旁通吸入管22c、殼體34及旁通吹出管 22d構成，一端連接於已形成在台框側壁46b之旁通吸入口 22a的旁通吸入管22c延著左側（與左側壁46b約正交，與前 面面板4約平行的方向），另一端連接殼體34之一端，而且， 5 一端連接殼體34之另一端之旁通吹出管22d向下方延伸並 向右方彎折，其另一端連接後導引構件48之一側壁48b的旁 通吹出口 22b。如此以殼體34構成旁通流路22之一部分的狀 態，可達到節省空間化，且以此等一連串的構造，透過旁 通吹出管22d而從靜電霧化裝置18確實將靜電霧向主流路 10 20誘導，而可將靜電霧放出至被空調室内。 旁通吸入口22a位於預濾器5與熱交換器6之間，即，位 於預濾器5且位於熱交換器6的上游侧，從前面吸入口 2a及 上面吸入口 2b吸入的空氣所含有的塵埃可藉預濾器5有效 地去除，因此可抑制塵埃侵入靜電霧化裝置18。藉此，能 15 有效防止塵埃堆積於靜電霧化裝置30，能穩定地放出靜電 霧。 如此於本實施樣態中，雖然以預濾器5兼具靜電霧化裝 置18與主流路20之預濾器的構造，但是藉此在保養上僅清 掃預濾器5即可，而不必分別進行揣掃，故可簡略化保養清 20掃。而且，於將於後述之具有預濾器自動清掃裝置的空氣 調節機中，不必對預濾器5特別的保養清掃，而能實現無保 養清理化。 相對於此，旁通吹出口 22b位於熱交換器6及至内風扇8 的下游側且係位於吹出口 1〇的附近，構成從旁通吹出口22b 200928244 吐出之靜電霧利用主流路20之空氣流而擴散並充滿房間内 整體。如此將旁通吹出口 22b設置位於熱交換器6之下游側 理由，係在於一旦設置於熱交換器6之上游側，則由於熱交 換器6為金屬製’因此荷電粒子之靜電霧之大部分（約8〜9 5成以上）會被熱交換器6吸收之故。將旁通吹出口 22b設置位 於室内風扇8之下游側理由，係在於一旦設置於室内風扇8 之上游側，則由於室内風扇8内部存在著亂流，因此通過室 内風扇8内部之空氣在衝擊室内風扇8各個部位的過程中， ® 靜電霧之一部分（約5成左右）會被吸收之故。 10 又，設置旁通吹出口 22b之後導引構件48之一側壁48b 的主流路20側，藉室内風扇8會對空氣流加諸預定的速度， 而會於側壁48b之主流路20側與旁通流路22侧產生壓力，相 對於旁通流路22 ’主流路2〇側相對性地構成呈低壓的負壓 部。因此’旁通送風風扇26以小容量者即可，並視情況也 15 可不設置旁通送風風扇26。 而且’旁通吹出管22d於與主流路20之合流點（旁通吹 ® 出口 22b)連接隔壁46c(後導引構件48之側壁48b)構成指向 相對於主流路20内之空氣流約正交的方向。此乃因靜電霧 化裝置30如上所述利用放電現象而產生靜電霧，必然地伴 20隨放電聲音而於放電聲音具有指向性之故。因此，於旁通 — 吹出管2 2 d於與主流路2 〇之合流點（旁通吹出口 2 2 b )，將旁通 流路22約平行地連接前面面板4的狀態，對於在室内機之前 方或斜前方的人，構成放電聲音極不具指向而可降低嗓音。 又’如第8圖所示，使旁通吹出管22d於與主流路20之 17 200928244 合流點相對於隔壁傾斜，並連接成相對於主流路20内之空 氣流指向上游側，則於進一步降低放電聲音之噪音上具有 效果。 又，在旁通吹出管22d所指向之方向指向主流路2〇内之 - 5二氣〃IL的下游方向而連接的情形下，祇要是預先不將其延 - 長線設成從吹出口 10伸出至外部的話，產生之放電聲音從 吹出口 10直接發出至外部的量少，而直接射入使用者之耳 的量亦少，因此可達到降低噪音效果。 如以上所說明，以隔壁46c分離主流路20與旁通流路 0 10 22，將用以產生靜電霧之靜電霧化裝置18設於將熱交換器6 予以旁通並連通主流路20的旁通流路22，因此，不通過熱 交換器6即可將未經濕度溫度調整之空氣供給至靜電霧化 裝置18，因此，於開冷氣時，可有效防止靜電霧化單元3〇 之帕耳帖元件36整體產生結露以提昇安全性，且於開暖氣 15 時，可確實產生靜電霧，不論空氣調節機的運轉模式，即， 無關季節而能穩定地產生靜電霧。 其次說明進一步設置了具有吸取並去除已附著於預濾 〇 器5之塵埃之吸取裝置之預濾器自動清掃裝置的空氣調節 機。一面參考第9圖一面說明換氣風扇單元16時，換氣風扇 2〇 單元16可為換氣專用，也可為兼具設置於具有預濾器自動 清掃裝置之室内機之吸取裝置之供氣用者。第9圖所示之換 氣風扇單元16在隔壁46c之旁通流路22側且被安裝於預濾 器自動清掃裝置的吸取裝置58内，但是，由於預濾器自動 清掃裝置為眾所周知者’因此一面參考第10圖一面簡單地 18 200928244 說明。預濾器自動清掃裝置之詳細的構造與運轉方法並無 特別的限定。 如第ίο圖所示，預濾器自動清掃裝置50具有可沿著預 濾器5表面而自由滑動的吸取喷嘴52,吸取噴嘴52藉著設置 5在預濾器5之上下端之—對導軌54，可與預濾器5保持極窄 的間隙而能圓滑地左右移動，附著於預濾器5之塵埃由吸取 喷嘴52吸取並去除。又，可自由彎曲之吸取管56之一端連 結於吸取喷嘴52，吸取管56之另一端連結於吸取量可改變 的吸取裝置58 ’而且，排氣管60連結於吸取裝置58並導出 10 至室外。 又，於吸取喷嘴52之上下方向的周圍，捲繞著沿著吸 取喷嘴52而可自由滑動的帶（未以圖式顯示）’於與吸取喷嘴 52之預濾器5對向之面’形成與預濾器5之縱長約相等之切 縫狀的喷嘴開口部’另一方面，於帶形成有預濾器5之縱長 15 之例如1/4長度之切缝狀的吸取孔 上述構造之預濾器自動清掃裝置5〇可因應需要而依序 清掃預滤器5之清掃範圍A、B、C、D ’吸取清掃範圍A時’ 以驅動帶並將吸取孔固定於範圍A位置的狀態’一面吸取而 一面將吸取喷嘴52從預濾器5右端驅動至左端的狀態，吸取 20清掃預濾器5之水平方向的範圍A。 其次，驅動帶並將吸取孔固定於範圍B位置’以此狀態 一面吸取而〆面將吸取喷嘴52從預濾器5左端驅動至右端 的狀態，此乃吸取清掃預濾器5之水平方向的範圍B。同樣 地也可吸取清掃預濾器5之範圍C、D。 19 200928244 附著於預濾器5而被吸取喷嘴52吸取的塵埃，經過吸取 管56、吸取裝置58、排氣管60而被排出至室外。 再參考第9圖’於吸取裝置58之吸入路徑形成開口部 62，且設有用以開閉此開口部62的阻尼器64，換氣風扇單 5元16於阻尼器64打開開口部62時作為換氣用，於進行吸取 清掃時藉著阻尼器64關閉開口部而作為從帶之吸取孔吸取 塵埃的吸取用。即’使用同一吸取裝置58可實現吸取清掃 機能與換氣機能。 又’第9圖中未以圖式顯示排氣管60,但是，排氣管60 10 連接於吸取裝置58之排氣口 58a。 第11圖表示不具有殼體34之靜電霧化裝置18八，此靜電 霧化裝置18A如第12圖所示組裝於室内機本體2内。或是， 組裝於第12圖所示之虛線區域18B(於第9圖所示之靜電霧 化裝置中，與設置於旁通流路22之下游側之靜電霧化裝置 I5 30及消音器32約同位置）内。此等，從室内機之正面或上面 觀看，靜電霧化裝置18A係配置於與換氣風扇單元16重疊的 位置，且係將靜電霧化裝置18A配置於換氣風扇單元16之開 口部62及阻尼器64附近，並係配置在以換氣風扇單元16所 進行之吸取空氣所流動的部分。 2〇 更詳細說明，第11圖之靜電霧化裝置18A係具有散熱部 28之靜電霧化單元30與消音器32安裝成一體，除了散熱部 28之靜電霧化單元30部分與消音器32收容於分別的殼體 (單元殼體66與消音器殼體68)，旁通吹出管22d之一側連接 並連通消音器殼體68，旁通吹出管22d之另一側連接並連通 200928244 5 Ο 10 15 20 主流路20。此情形下，藉著隔壁46c從主流路20分離，而形 成於與未以圖式顯示之本體蓋之左侧面之間，配設有換氣 風扇單元16、靜電霧化裝置18A等之收容部22e取代前述之 旁通吸入管22c與殼體34，且收容旁通吹出管22d而構成旁 通流路22。 又’旁通吹出管22d以相對於主流路20之空氣流指向的 方向而達到降低嗓音的情形如之前所述，但是，並非一定 必要者’而也可將消音器殼體68直接連接於旁通吹出口 22b。如此一來，可使靜電霧化裝置18A之構造更簡單化。 但是’為了降低嗓音，考量方向為必要的情形與旁通吹出 管22d相同。 如此一來，透過預濾器5而被吸入本體2内的空氣從預 濾器5之下游側的旁通吸入口22a被吸入收容部22e，其空氣 流的方向，從正面觀看室内機本體2，係相對於流動於主流 路20之空氣流的方向呈平行流動於收容部22e内。藉著如此 流動於收容部22e内的空氣而冷卻散熱部28，且從形成在單 元殼體66之開口部（未以圖式顯示）被收入靜電霧化單元3〇 内。 以如此的構造，從室内機之正面或上面，與換氣風扇 單元16重疊之換氣風扇單元16之周圍空間構成旁通流路， 可有效活用換氣風扇單元16之、靜電霧化裝置18A等之收容 部22e而達到節省空間化。又，此構造的話，高電壓傳送器 24係被配置於換氣風扇單元16、靜電霧化裝置18A等之收容 部22e中的任意部位，而不設置旁通送風風扇26。 21 200928244 又’如此從正面觀看室内機本體2，以將旁通流路22 構成相對於通過主流路2〇之空氣流呈平行流動的狀態，如 上所述以所謂隔壁46c之簡略的構造而能將主流路2〇與旁 通流路22分岐，因此能容易形成旁通流路22而可刪減構件 - 5 數量。 而且’以構成本構造的狀態，能將靜電霧化裝置18A 之預濾器與主流路2〇之預濾器以預濾器5共有化。對於共有 化之效果則如之前所述’因此省略其詳細說明。 又’可在設於換氣風扇單元16之後部之台框46的下部 ◎ 10附近’形成開口 46d以使連接室内機與室外機之配管（未以 圖式顯示）拉出。上述旁通吸入口 22a係用以將空氣吸入收 容部22e而形成在隔壁46c(台框側壁46b)之收容部22e的一 個開口 ’透過預濾器5而與室内機之外部連通著，但是，形 成在台框46之下部的開口 46d則構成收容部22e與室内機之 15 外部直接連接而吸入周圍空氣的開口。如此構造的話，則 收容部22e構成也將預滤器5旁通的旁通流路。因此，構成 被吸入靜電霧化裝置18A之空氣從開口 46d流入而不通過預 © 濾器5，因此可因應需要而另外設置靜電霧化裝置18A用之 預濾器即可。又，即使是形成開口46d之構造，從室内機之 20 正面或上面觀看，靜電霧化裝置18A配設於與換氣風扇單元 16重疊之位置的情形未改變，可有效活用收容部22e而達到 - 節省空間化的情形相同。 如上所述，旁通吸出口 22b之主流路20側’藉室内風扇 8對空氣流賦與預定速度的狀態而產生壓力差並構成被吸 22 200928244 5 10 15 20 引的負壓部，因此，即使不設置旁通送風風扇26，亦能以 透過旁通吹出管22d而從旁通流路之收容部22e朝向主流路 20被吸引之空氣冷卻散熱部28 ’因此藉靜電霧化單元20產 生之靜電霧被吸引至主流路20而能放出至被空調室内。 又，散熱部28如虛線區域18B在開口部62及阻尼器64之附 近，且配置於被吸入開口部62之空氣流動的部分’因此能 以換氣風扇單元16所吸取空氣來冷卻° 又，如第12圖所示，以將靜電霧化裝置18A之散熱部28 接近設置於吸取裝置58之開口部62來設置，可藉著吸入開 口部62之空氣而更加冷卻散熱部28，可促進來自靜電霧化 單元30的散熱。又，使用換氣專用之風扇作為換氣風扇單 元16的情形下，由於不設置阻尼器64，因此以將散熱部28 接近換氣風扇單元16之吸入口而配置的狀態，可更有效率 地冷卻散熱部28。 如以上說明，依據上述構造時，以隔壁46c分離主流路 20與構成旁通流路的收容部22e，並將用以產生靜電霧之靜 電霧化裝置18A設於收容部22e，因此不通過熱交換器6之未 被調整溫濕度之空氣可被供給至靜電霧化裝置18A，爰此， 於冷氣下，可有效防止於靜電霧化裝置3〇之帕耳帖元件36 整體產生結露而提昇安全性，且於暖氣下，可確實產生靜 電霧，無關空氣調節機之運轉模式，即，無關季節可穩定 地產生靜電霧。 產業上之可利用性 本發明之空氣調節機可確實產生靜電霧，且充分考慮 23 200928244 到安全性或噪音，因此可作為包含一般家庭用之空氣調節 機之各式各樣空氣調節機使用而極具有用性。 【圖式簡單說明3 第1圖係去除一部分狀態下之本發明之空氣調節機之 _ 5 室内機的立體圖。 第2圖係第1圖之室内機的概略縱剖面圖。 第3圖係設於第1圖之室内機之靜電霧化裝置的立體 圖。 第4圖表示第1圖之室内機之框體之一部分與靜電霧化 © 10 裝置的正面圖。 第5圖係靜電霧化裝置之概略構成圖。 第6圖係靜電霧化裝置之方塊圖。 第7圖表示靜電霧化裝置對室内機本體之安裝狀態的 立體圖。 15 第8圖表示靜電霧化裝置對室内機本體之安裝狀態之 變形例的立體圖。 第9圖表示靜電霧化裝置與換氣風扇之位置關係之第1 〇 圖之室内機的側面圖。 第10圖係設於第1圖之室内機之預濾器自動清掃裝置 20 的立體圖。 第11圖表示靜電霧化裝置之變形例的立體圖。 -

Description of the Invention: [Technical Field 3 of the Invention] The present invention relates to an air conditioner having an air purifying function for purifying indoor air. L. Prior Art 3 BACKGROUND OF THE INVENTION A conventional air conditioner has a deodorizing function, for example, a prefilter for air cleaning by a suction port of a chamber internal machine to adsorb odor into 10 points, or by borrowing The odorizing unit having an oxidative decomposition function in the middle of the air blowing path adsorbs the odor component. However, the air conditioner having the deodorizing function removes the odor component contained in the air taken in from the air intake, and therefore cannot remove the odor component contained in the indoor air, and adheres to the window or the wall.

[Embodiment 3] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. 15 The air conditioner is usually constituted by an outdoor unit and an indoor unit that are connected to each other by a refrigerant pipe. Figs. 1 and 2 show an indoor unit of the air conditioner of the present invention. As shown in Fig. 1 and Fig. 2, the indoor unit has the suction port 2a and the upper suction port 2b as suction ports for taking in indoor air into the main body 2. The front suction 20 inlet 2a has a movable front panel that can be opened and closed freely (hereinafter Referring only to the front surface 'board' 4, when the front panel 4 is in close contact with the main body 2 and the front suction port 2a is closed with respect to the air conditioner, the front panel 4 moves in a direction away from the main body 2 when the air conditioner is operated. The front suction port 2a is opened. The inside of the main body 2 includes a prefilter 5 disposed on the downstream side of the front suction port 2a and the upper suction port 11 200928244 2b for removing dust contained in the air, and is disposed on the downstream side of the preheater 5 and used for The indoor fan 8 for heat exchange (5) from the front suction port and the upper suction port 2b, the heat exchange (5) for heat exchange, and the air for heat exchange by the heat exchanger 6 for the slave fan 8 The upper and lower blades 12 that open and close the air blowing port 19 and blow the air blowing direction up and down, and the upper and lower blades 14 that change the air blowing direction to the left and right. Moreover, the upper portion of the front panel 4 is coupled to the upper portion of the main body 2 through a plurality of arms (not shown) provided at both ends thereof to drive and control a driving motor coupled to one arm of the plurality of arms (not shown) In the state of the state 10, when the air conditioner is continuously rotated, the front panel 4 moves forward from the position at which the air conditioner is stopped (the closed position of the front suction port 2a). Similarly, the upper and lower wings 12 are connected to the lower portion of the body 2 through a plurality of arms (not shown) provided at both ends thereof. Further, a ventilation fan unit for exchanging indoor air is provided at an end portion on one side of the indoor unit (the left end portion 15 is viewed from the front of the indoor unit and is on the side of the bypass passage 22 which will be described later as the partition wall 46c). 16. The rear side of the ventilation fan unit 16 is provided with an electrostatic atomizing device 18 for generating an electrostatic mist and having an air purifying function for purifying indoor air. Further, Fig. 1 shows a state in which the main body 2 cover (not shown) for covering the front panel 4 and the main body 2 is removed, and Fig. 2 is a view for explaining the connection position between the indoor unit main body 2 and the electrostatic atomizing device 18. This shows a state in which the electrostatic atomization device 18 that has been housed inside the body 2 is separated from the body 2. The electrostatic atomizing device 18 is actually in the shape shown in Fig. 3, and is attached to the left side portion of the body 2 as shown in Fig. 1 or Fig. 4. 200928244 As shown in Figs. 2 to 4, the electrostatic atomization is placed in the main flow path 20 of the i8 from the front suction port and the upper suction port 2b via the heat exchanger 6, the indoor fan 8, and the like, and communicates with the air outlet 10. In the middle of the bypass flow path 22 bypassing the heat exchanger 6 and the indoor fan 8, and on the upstream side 5 of the bypass flow path 22, a high-pressure transmitter 24 and a bypass blower fan constituting a high-voltage power source are provided. On the downstream side of the bypass flow path 22, an electrostatic atomization unit 3A and a muffler (4) having a heat dissipation portion 28 for promoting heat dissipation of the electrostatic atomization device are provided. Therefore, the high-pressure conveyor 24, the bypass air blowing fan unit 28, the electrostatic atomizing unit 30, and the muffler 32 are disposed in order from the upstream side, and are housed in the casing 34 constituting the portion of the H) through-flow path 22. . By accommodating the casing 34 and improving the assemblability, the flow path can be formed in the casing 34, so that the space can be saved, and the air flow constituted by the bypass blower fan 26 can surely touch the high voltage of the trigger heat portion. The device 24 and the heat radiating portion 28 can cool the heat radiating portion 28, and can reliably introduce the electrostatic mist generated from the electrostatic atomizing device 30 into the air outlet 1510 of the air conditioner, and discharge the generated static mist into the air-conditioned room. Further, the casing 34 is viewed from the front of the indoor unit body 2 in a direction in which the air flow flowing inside the casing 34 is parallel to the direction of the air flow flowing through the main passage 2, thereby When viewed from the front of the indoor unit body 2, it can be disposed adjacent to the position overlapping with the ventilation fan unit 16, and the space can be saved. Further, the high voltage transmitter 24 does not have to be housed in the casing 34. However, it is preferably housed in the casing 34 in order to suppress the temperature rise or space saving by the ventilation of the bypass passage. Inside. The well-known static 13 200928244 electrospray unit 30 will be described with reference to Figs. 5 and 6. As shown in FIG. 5, the "electrostatic atomizing unit 30" is a heat dissipating portion (for example, a cooling fan) that is thermally coupled to the plurality of Peltier elements 36 having the heat dissipating surface 26a and the cold surface 36b, and is connected to the heat dissipating surface 36a. 28. The discharge electrode 38 that is thermally and intimately adhered to the cooling surface 36a through the electrically insulating material 5 (not shown) is constituted by the counter electrode 40 which is disposed at a predetermined distance from the discharge electrode 38. Further, as shown in Fig. 6, the control unit 42 (refer to Fig. 1) disposed in the vicinity of the ventilation fan unit 16 is connected to the Peltier drive power source to transmit the switch 24' with the high voltage. The Peltier drive power source 44 is electrically connected, and on the other hand, the discharge electrode 38 and the counter electrode 4 are electrically connected to the high voltage transmitter 24. Further, in the electrostatic atomizing device 3, in order to generate electrostatic mist from the high voltage discharge of the discharge electrode 38, the counter electrode 4A may not be provided. For example, one terminal of the high-voltage power source is connected to the discharge electrode 38, and the other terminal is connected to the frame to form a discharge between the portion of the discharge electrode 38 adjacent to the frame connection structure and the discharge electrode 38. With such a configuration, the configuration in which the frame is connected can be regarded as the counter electrode 40. In the electrostatic atomizing device 30 of the above configuration, when the controller 42 controls the Peltier driving power source 44 to flow current to the Peltier element 36, heat is moved from the cold 20 face 36 to the heat radiating surface 36a to discharge the electrode. The state in which the temperature of 38 is lowered is dew condensation at the discharge electrode 38. When the high voltage conversion unit 24 is controlled by the control unit 42 to apply a high voltage to the discharge electrode 38 to which the dew condensation water is attached, a discharge phenomenon occurs in the dew condensation water to generate an electrostatic mist having a particle diameter of a nanometer size. Further, in the present embodiment, a negative high voltage power supply is used as the high voltage conversion 200928244 portion 24, so that the electrostatic mist is negatively charged. Further, in the present embodiment, as shown in Fig. 7, the main channel 20 has the rear wall portion 46a constituting the frame 46 of the main body 2 and the two side walls extending forward from both end portions of the rear wall portion 46a (the 7 shows only the left side wall 46b, the rear side wall 48a of the guide member (air supply guide) 48 formed on the lower side of the frame 46 " 5, and the two side walls extending forward from both end portions of the rear wall 48a (only the left side wall is shown in Fig. 7) 48b, one side wall (left side wall) 46b of the frame 46 and one side wall (left side wall) 48b of the rear guide member 48 constitute the bypass flow path 22 from the main flow path. 20 separates the partition wall 46c of the crucible. Further, a side wall 46b of the frame 46 forms a bypass suction port 22a of the bypass flow path 2210, and on the other hand, a side wall 48b of the rear guide member 48 forms a bypass air outlet 22b of the bypass flow path 22. . When the air conditioner is in cold air, the relative humidity of the low temperature air passing through the heat exchanger 6 of the indoor unit is high, and in the case where the electrostatic atomizing device 18 is provided with the Peltier element 36 for replenishing moisture, not only the Peltier The pin-like 15 discharge electrode 38' of the element 36 is susceptible to condensation on the entire Peltier element 36. On the other hand, in the heating, the high temperature air passing through the heat exchanger 6 of the indoor unit is low in relative humidity, so that the discharge electrode 38 of the Peltier element 36 does not condense extremely high. With the above configuration, the main flow path 20 and the bypass flow path 22 are separated by the partition wall 46c, and the electrostatic atomization device 18 for generating electrostatic mist is provided in the bypass flow path 22' - not passing through the heat exchanger 6 The air whose temperature and humidity are adjusted can be supplied to the electrostatic atomization device 18. In this way, it is possible to effectively prevent condensation of the entire Peltier element 36 of the electrostatic atomizing device 30 in the cold air, thereby improving safety. Moreover, it is possible to reliably generate electrostatic mist during heating. 15 200928244 The bypass flow path 22 is constituted by the bypass suction pipe 22c, the casing 34, and the bypass blow pipe 22d, and one end is connected to the bypass suction pipe 22c which is formed in the bypass suction port 22a of the frame side wall 46b, and extends to the left side. (about orthogonal to the left side wall 46b, in a direction approximately parallel to the front panel 4), the other end is connected to one end of the housing 34, and the bypass end outlet pipe 22d, which is connected to the other end of the housing 34 at one end, extends downward and The right side is bent, and the other end thereof is connected to the bypass air outlet 22b of the side wall 48b of the rear guiding member 48. In such a manner that the casing 34 constitutes a part of the bypass flow path 22, space saving can be achieved, and the series of structures are passed through the bypass blowing pipe 22d to reliably discharge the electrostatic mist from the electrostatic atomizing device 18 to the main flow path. 10 20 induces, and the electrostatic mist can be released into the air-conditioned room. The bypass suction port 22a is located between the prefilter 5 and the heat exchanger 6, that is, on the upstream side of the prefilter 5 and on the heat exchanger 6, and the dust contained in the air taken in from the front suction port 2a and the upper suction port 2b. The prefilter 5 can be effectively removed, so that the dust can be prevented from entering the electrostatic atomizing device 18. Thereby, the dust 15 can be effectively prevented from accumulating in the electrostatic atomizing device 30, and the electrostatic mist can be stably released. In this embodiment, although the prefilter 5 has both the electrostatic atomizing device 18 and the prefilter of the main flow path 20, it is only necessary to clean the prefilter 5 in maintenance, and it is not necessary to separately perform the sweeping. Therefore, the maintenance can be simplified and cleaned. Further, in the air conditioner having the prefilter automatic cleaning device which will be described later, it is not necessary to perform special maintenance cleaning of the prefilter 5, and maintenance-free cleaning can be realized. On the other hand, the bypass air outlet 22b is located on the downstream side of the heat exchanger 6 and the inner fan 8, and is located in the vicinity of the air outlet 1〇, and constitutes the air flow of the static mist using the main flow path 20 discharged from the bypass air outlet 22b 200928244. And spread and fill the whole room. The reason why the bypass air outlet 22b is disposed on the downstream side of the heat exchanger 6 is that the heat exchanger 6 is made of metal when it is disposed on the upstream side of the heat exchanger 6, so that most of the electrostatic mist of the charged particles (about 8 to 95% or more) will be absorbed by the heat exchanger 6. The reason why the bypass air outlet 22b is provided on the downstream side of the indoor fan 8 is that once it is installed on the upstream side of the indoor fan 8, since there is a turbulent flow inside the indoor fan 8, the air passing through the inside of the indoor fan 8 is in the impact chamber. During the various parts of the fan 8, one part of the electrostatic mist (about 50%) will be absorbed. Further, after the bypass air outlet 22b is provided, the side wall 48b of the guide member 48 is provided on the side of the main flow path 20, and the indoor fan 8 applies a predetermined speed to the air flow, and is disposed on the side of the main flow path 20 of the side wall 48b. A pressure is generated on the side of the flow path 22, and a negative pressure portion having a low pressure is formed opposite to the side of the main flow path 2' of the bypass flow path 22'. Therefore, the bypass blower fan 26 may have a small capacity, and the bypass blower fan 26 may not be provided as the case may be. Further, the bypass bypass pipe 22d is connected to the junction point (main bypass blower outlet 22b) of the main flow path 20 to connect the partition wall 46c (the side wall 48b of the rear guide member 48) to be orthogonally directed to the air flow in the main flow path 20. The direction. This is because the electrostatic atomizing device 30 generates an electrostatic mist by the discharge phenomenon as described above, and inevitably has a directivity with respect to the discharge sound with the discharge sound. Therefore, in the bypass-blowing pipe 2 2 d at the junction with the main flow path 2 (the bypass air outlet 2 2 b ), the bypass flow path 22 is connected to the front panel 4 in parallel, for the indoor unit The person who is in front of or in front of the front makes the discharge sound extremely non-directional and can reduce the arpeggio. Further, as shown in Fig. 8, the bypass blow-off pipe 22d is inclined with respect to the partition wall at the junction with the main flow path 20, 200928244, and is connected to the upstream side with respect to the air flow in the main flow path 20, thereby further reducing The noise of the discharge sound has an effect. Further, in a case where the direction in which the bypass blowing pipe 22d is directed is directed to the downstream direction of the -2 gas cylinder IL in the main flow path 2, the extension-long line is not set to extend from the air outlet 10 in advance. When it is sent to the outside, the generated discharge sound is directly emitted from the air outlet 10 to the outside, and the amount of the direct discharge into the user's ear is small, so that the noise reduction effect can be achieved. As described above, the main flow path 20 and the bypass flow path 0 10 22 are separated by the partition wall 46c, and the electrostatic atomization device 18 for generating the electrostatic mist is provided to bypass the heat exchanger 6 and communicate with the main flow path 20. Since the flow path 22 is passed through, the air that has not been adjusted by the humidity temperature can be supplied to the electrostatic atomization device 18 without passing through the heat exchanger 6. Therefore, when the cold air is opened, the electrostatic atomization unit 3 can be effectively prevented. The element 36 is entirely dew condensation to improve safety, and when the heating unit 15 is turned on, electrostatic mist can be surely generated, and the electrostatic mist can be stably generated regardless of the operation mode of the air conditioner, that is, regardless of the season. Next, an air conditioner further provided with a pre-filter automatic cleaning device for sucking and removing the suction device attached to the dust of the pre-filter 5 will be described. When the ventilation fan unit 16 is described with reference to FIG. 9 , the ventilation fan 2 〇 unit 16 may be dedicated to ventilation, or may be used for air supply of a suction device provided in an indoor unit having a pre-filter automatic cleaning device. By. The ventilation fan unit 16 shown in Fig. 9 is attached to the suction device 58 of the prefilter automatic cleaning device on the side of the bypass wall 46c and is attached to the suction device 58 of the prefilter automatic cleaning device. However, since the prefilter automatic cleaning device is well known, Refer to Figure 10 for a simple description of 18 200928244. The detailed structure and operation method of the prefilter automatic cleaning device are not particularly limited. As shown in Fig. 00, the pre-filter automatic cleaning device 50 has a suction nozzle 52 that is slidable along the surface of the pre-filter 5, and the suction nozzle 52 is disposed on the lower end of the pre-filter 5 by means of a pair of guide rails 54. The gap between the prefilter and the prefilter 5 is smoothly moved to the left and right, and the dust adhering to the prefilter 5 is sucked and removed by the suction nozzle 52. Further, one end of the freely bendable suction pipe 56 is coupled to the suction nozzle 52, and the other end of the suction pipe 56 is coupled to the suction device 58' whose suction amount can be changed. Further, the exhaust pipe 60 is coupled to the suction device 58 and is led to the outside of the suction device 58. . Further, around the suction nozzle 52, a belt (not shown) that is slidable along the suction nozzle 52 is wound around the surface opposite to the prefilter 5 of the suction nozzle 52. The pre-filter 5 has a slit-shaped nozzle opening portion having an approximately equal length. On the other hand, a slit-shaped suction hole having a longitudinal length 15 of the prefilter 5 is formed, for example, a pre-filter having the above configuration. The automatic cleaning device 5〇 can sequentially clean the cleaning range A, B, C, and D of the prefilter 5 as needed. When the cleaning range A is sucked, the state in which the driving belt is fixed and the suction hole is fixed to the range A is sucked. While sucking the suction nozzle 52 from the right end of the prefilter 5 to the left end, the suction 20 cleans the range A of the prefilter 5 in the horizontal direction. Next, the driving belt and the suction hole are fixed at the range B position. In this state, the suction nozzle 52 is driven from the left end of the prefilter 5 to the right end, which is the range B of the horizontal direction of the cleaning prefilter 5. . Similarly, the range C, D of the cleaning prefilter 5 can be aspirated. 19 200928244 The dust adhering to the prefilter 5 and sucked by the suction nozzle 52 is discharged to the outside through the suction pipe 56, the suction device 58, and the exhaust pipe 60. Referring to FIG. 9 again, the opening portion 62 is formed in the suction path of the suction device 58, and a damper 64 for opening and closing the opening portion 62 is provided. The ventilating fan unit 5 is replaced by the damper 64 when the opening portion 62 is opened. For gas use, the opening is closed by the damper 64 during the suction cleaning, and the suction is taken up from the suction hole of the belt. That is, the suction and discharge functions and the ventilating function can be realized by using the same suction device 58. Further, in Fig. 9, the exhaust pipe 60 is not shown in the drawings, but the exhaust pipe 60 10 is connected to the exhaust port 58a of the suction device 58. Fig. 11 shows an electrostatic atomizing device 18 which does not have a casing 34. The electrostatic atomizing device 18A is assembled in the indoor unit body 2 as shown in Fig. 12. Or, it is assembled in the dotted line region 18B shown in Fig. 12 (in the electrostatic atomization device shown in Fig. 9, and the electrostatic atomization device I5 30 and the muffler 32 provided on the downstream side of the bypass flow path 22). About the same position). The electrostatic atomizing device 18A is disposed at a position overlapping the ventilation fan unit 16 and is disposed in the opening portion 62 of the ventilation fan unit 16 and the electrostatic atomizing device 18A is disposed on the front side or the upper surface of the indoor unit. The vicinity of the damper 64 is disposed in a portion where the suction air by the ventilation fan unit 16 flows. 2A, the electrostatic atomizing unit 30 having the heat dissipating portion 28 is integrally mounted with the muffler 32 except for the portion of the electrostatic atomizing unit 30 of the heat dissipating portion 28 and the muffler 32. The respective casings (the unit casing 66 and the muffler casing 68) are connected to one side of the bypass blow pipe 22d and communicate with the muffler casing 68, and the other side of the bypass blow pipe 22d is connected and connected to 200928244 5 Ο 10 15 20 Mainstream road 20. In this case, the partition wall 46c is separated from the main flow path 20, and is disposed between the left side surface of the body cover not shown in the drawing, and is housed in the ventilation fan unit 16 and the electrostatic atomization device 18A. The portion 22e constitutes the bypass flow path 22 instead of the bypass suction pipe 22c and the casing 34, and accommodates the bypass blow pipe 22d. Further, the case where the bypass blowout pipe 22d reaches the lowering of the sound with respect to the direction in which the air flow of the main flow path 20 is directed is as described above, but it is not necessary to also connect the muffler housing 68 directly to the side. The outlet 22b is blown. As a result, the configuration of the electrostatic atomization device 18A can be simplified. However, in order to reduce the arpeggio, it is necessary to consider the direction as the bypass blowout pipe 22d. As a result, the air sucked into the main body 2 through the prefilter 5 is sucked into the accommodating portion 22e from the bypass suction port 22a on the downstream side of the prefilter 5, and the direction of the air flow is viewed from the front side of the indoor unit body 2, The direction of the air flow flowing through the main flow path 20 flows in parallel in the accommodating portion 22e. The heat radiating portion 28 is cooled by the air flowing in the accommodating portion 22e, and is taken into the electrostatic atomizing unit 3 from the opening portion (not shown) formed in the unit casing 66. With such a configuration, the space around the ventilation fan unit 16 overlapping the ventilation fan unit 16 on the front or the upper surface of the indoor unit constitutes a bypass flow path, and the electrostatic atomization device 18A of the ventilation fan unit 16 can be effectively utilized. The storage unit 22e is equal to the space saving. Further, in this configuration, the high voltage transmitter 24 is disposed in any portion of the accommodating portion 22e such as the ventilating fan unit 16 and the electrostatic atomizing device 18A, and the bypass air blowing fan 26 is not provided. 21 200928244 Further, the indoor unit body 2 is viewed from the front side so that the bypass flow path 22 is configured to flow in parallel with the air flow passing through the main flow path 2, and as described above, the simple structure of the partition wall 46c can be used. Since the main flow path 2〇 and the bypass flow path 22 are branched, the bypass flow path 22 can be easily formed and the number of members - 5 can be deleted. Further, in the state in which the structure is constructed, the prefilter of the electrostatic atomizing device 18A and the prefilter of the main channel 2 can be shared by the prefilter 5. The effect of the sharing is as described above, and thus the detailed description thereof is omitted. Further, an opening 46d may be formed in the vicinity of the lower portion ◎ 10 of the frame 46 provided at the rear portion of the ventilation fan unit 16 to pull out the piping (not shown) connecting the indoor unit and the outdoor unit. The bypass suction port 22a is configured to allow air to be sucked into the accommodating portion 22e to form an opening '' formed in the accommodating portion 22e of the partition wall 46c (the frame side wall 46b) through the prefilter 5 to communicate with the outside of the indoor unit, but is formed. The opening 46d at the lower portion of the frame 46 constitutes an opening in which the accommodating portion 22e is directly connected to the outside of the indoor unit 15 to take in the surrounding air. With such a configuration, the accommodating portion 22e constitutes a bypass flow path that bypasses the prefilter 5. Therefore, the air constituting the suctioned electrostatic atomizing device 18A flows in from the opening 46d without passing through the pre-filter 5, so that the pre-filter for the electrostatic atomizing device 18A can be separately provided as needed. Further, even in the structure in which the opening 46d is formed, the electrostatic atomizing device 18A is disposed at a position overlapping the ventilation fan unit 16 as viewed from the front or the upper surface of the indoor unit 20, and the storage portion 22e can be effectively utilized. - The same is true for space saving. As described above, the main flow path 20 side of the bypass suction port 22b generates a pressure difference by the state in which the indoor fan 8 gives a predetermined speed to the air flow, and constitutes a negative pressure portion which is sucked by 22 200928244 5 10 15 20 , and therefore, Even if the bypass blower fan 26 is not provided, the heat radiating portion 28 can be cooled by the air that is sucked from the accommodating portion 22e of the bypass flow path toward the main passage 20 through the bypass blow-off pipe 22d. Therefore, it is generated by the electrostatic atomizing unit 20. The electrostatic mist is attracted to the main flow path 20 and can be discharged to the air-conditioned room. Further, the heat radiating portion 28 is in the vicinity of the opening portion 62 and the damper 64 in the vicinity of the opening portion 62 and the damper 64, and the portion where the air that is sucked into the opening portion 62 flows can be cooled by the air taken in by the ventilating fan unit 16. As shown in Fig. 12, the heat radiating portion 28 of the electrostatic atomizing device 18A is provided close to the opening portion 62 of the suction device 58, and the heat radiating portion 28 can be further cooled by the air sucked into the opening portion 62, thereby facilitating the promotion of the heat radiating portion 28. The heat dissipation of the electrostatic atomizing unit 30. Further, in the case where the fan dedicated to ventilation is used as the ventilation fan unit 16, since the damper 64 is not provided, the heat dissipating portion 28 can be disposed closer to the suction port of the ventilation fan unit 16 to more efficiently The heat radiating portion 28 is cooled. As described above, according to the above configuration, the main flow path 20 and the accommodating portion 22e constituting the bypass flow path are separated by the partition wall 46c, and the electrostatic atomization device 18A for generating electrostatic mist is provided in the accommodating portion 22e, so that heat exchange is not performed. The air of the unregulated temperature and humidity of the device 6 can be supplied to the electrostatic atomizing device 18A, thereby effectively preventing the condensation of the Peltier element 36 of the electrostatically atomizing device 3 as a whole under cold air to improve safety. And under the heating, the electrostatic mist can be surely generated, irrespective of the operation mode of the air conditioner, that is, the static mist can be stably generated irrespective of the season. INDUSTRIAL APPLICABILITY The air conditioner of the present invention can surely generate an electrostatic mist, and fully considers 23 200928244 to safety or noise, and thus can be used as a variety of air conditioners including air conditioners for general household use. Very useful.
