本発明は静電霧化装置を搭載した空気調和機にかかり、特に、霧化用水の供給機構の改良に関する。   The present invention relates to an air conditioner equipped with an electrostatic atomizer, and more particularly to an improvement in a mechanism for supplying atomization water.

空気調和機は室内空気を熱交換器に循環させて、加熱，冷却，除湿機能などにより調整し、これを室内に吹出すことにより室内を空気調和する。このとき、温度，湿度の調節以外にも様々な機能を付加し、室内を清浄で、快適な空間にすることが行われている。   An air conditioner circulates indoor air through a heat exchanger, adjusts it by heating, cooling, dehumidifying functions, and the like, and blows the air into the room to air condition the room. At this time, various functions other than temperature and humidity control are added to make the room clean and comfortable.

室内には、生活に付随して種々の臭いの発生源が生じ、そのあるものは鼻の臭気細胞を刺激し、臭いとして感知される。これらの臭い発生源は、気体，小液滴，微細な塵埃などであり、いずれも、放置しておくと宇宙線などにより電離した空気中のイオンなどと衝突して帯電したり、重力のため沈降したり、気流により壁に衝突したりして、室内の壁，家具，床，天井などの固定物に吸着され室内の空気中から取除かれ、または、活性物質と遭遇し分解，変成されて、臭いは消えてしまう。しかし、分解されないで、部屋の壁や床などに吸着，沈降した臭いの発生源は、温度が上がったり、風が当ったり、掃除で舞い上がったりすると、また、室内空気に浮遊することになり、臭いとして感じられるようになる。   In the room, various odor sources are generated in connection with life, some of which stimulate nasal odor cells and are perceived as odor. The sources of these odors are gas, small droplets, fine dust, etc., all of which are charged by collision with ions in the air ionized by cosmic rays, etc. It sinks or collides with the wall due to air current, and is adsorbed by fixed objects such as indoor walls, furniture, floors, ceilings, etc. and removed from indoor air, or encounters active substances and decomposes and transforms. The smell disappears. However, the source of the odor that is adsorbed and settled on the walls and floors of the room without being decomposed is floating in the room air if the temperature rises, the wind hits, or it rises by cleaning, and the odor Will feel as.

このように、吸着などにより室内の壁などに付着している臭いの発生源を分解，変成するため、ＯＨラジカルなどの活性物質を微細な水滴に付与して、長寿命化し、臭いの発生源に遭遇させ、脱臭する試みが行われている。   In this way, in order to decompose and modify the source of odor adhering to indoor walls by adsorption, etc., active substances such as OH radicals are applied to fine water droplets, extending the service life, and generating sources of odor Attempts have been made to deodorize and deodorize.

そのひとつとして、室内に吹出す空気に静電霧化方式により帯電した微細粒の水を放出し、室内を脱臭する方法が考えられ、これを具現化するために種々の工夫が凝らされている。   As one of them, a method of deodorizing the interior of the room by discharging fine particles of water charged by the electrostatic atomization method into the air blown into the room can be considered, and various ideas have been devised to realize this. .

この種の従来技術として、特開２００５−２５４２０８号公報，特開２００７−１３７２８２号公報，特開２００５−１３１５４９号公報，特開２００３−１７２９７号公報，実公平０７−０２８４９６号公報，実公平０７−０４０９０２号公報が知られている。   As this kind of prior art, JP 2005-254208 A, JP 2007-137282 A, JP 2005-131549 A, JP 2003-17297 A, JP 07-028496 A, JP 07 07. No. 040902 is known.

特許文献２は、空調ユニットに設けたダクト内のベント吹出口近傍に静電霧化装置を配設し、この静電霧化装置にペルチェ素子を設け、このペルチェ素子の低温部で空調風に含まれる水分を結露させて結露水を得る。この結露水に高電圧を印加してナノメーターサイズの微細な水の粒子を得るとともに、この粒子に帯電させる。この帯電した水の粒子を空調風に乗せて車室内に行き渡らせて、水の補給作業を不要にして快適な空調空間を手軽に実現できる空調装置について述べている。   In Patent Document 2, an electrostatic atomizer is disposed in the vicinity of a vent outlet in a duct provided in an air conditioning unit, a Peltier element is provided in the electrostatic atomizer, and air is conditioned at a low temperature portion of the Peltier element. Condensed water is obtained by condensing the contained water. A high voltage is applied to the condensed water to obtain nanometer-sized fine water particles, and the particles are charged. It describes an air conditioner that can easily realize a comfortable air-conditioned space by eliminating the need for water replenishment work by placing the charged water particles on the air-conditioned wind and spreading them in the passenger compartment.

特許文献３は、静電霧化装置を、毛細管現象によって水を搬送する電極（水搬送部）と、この電極（水搬送部）への水の供給手段としてペルチェ素子等の吸熱面を冷却して空気中の水分を結露させる手段と、電極（水搬送部）に電圧を印加して水分を霧化する構成が開示されている。これにより、使用者に水補給の手間を強いることなく且つ、水中の不純物が電極（水搬送部）に析出して付着しないようにしてメンテナンスフリーとしている。   Patent Document 3 uses an electrostatic atomizer to cool an endothermic surface such as a Peltier element as an electrode (water transport unit) that transports water by capillary action and water supply means to this electrode (water transport unit). A means for condensing moisture in the air and a configuration for atomizing the moisture by applying a voltage to the electrode (water transport unit) are disclosed. Thereby, it is possible to maintain the maintenance without forcing the user to replenish water and preventing impurities in the water from depositing and adhering to the electrode (water transport section).

特許文献４は、空気清浄器などに利用される放電装置において、電極が点状の放電部を有し、この放電部がその表面に水などの導電性液体を毛細管現象を利用して供給すること、及びペルチェ素子などの冷却手段により放電部を冷却して表面に空気中の水分を凝縮してメンテナンスフリーとする構成が開示されている。   Patent Document 4 discloses a discharge device used for an air purifier or the like, in which an electrode has a dot-like discharge portion, and this discharge portion supplies a conductive liquid such as water to the surface of the discharge portion using a capillary phenomenon. In addition, a configuration is disclosed in which the discharge portion is cooled by a cooling means such as a Peltier element to condense moisture in the air on the surface to make it maintenance-free.

現在、家庭用の空気調和機は、環境への配慮が求められ、省資源，省エネを強く要求されるようになった。加えて、使用時にも室内の環境を悪化させずに、快適にする製品が求められている。   Currently, home air conditioners are required to be environmentally friendly, and resource and energy savings are strongly demanded. In addition, there is a need for products that can be made comfortable without deteriorating the indoor environment during use.

特許文献１では図８のように放熱部，水生成部を吹出し風路に置くので、吹出し気流が乱れ、風量の減少を招いたり、騒音の原因になったりする。また、冷房運転時には、気流の乱れで局部的な露付が発生し空気調和機の周囲を汚す恐れがある。更に、暖房時には水生成部が暖房の温風に曝されるため、水生成部の冷却が不充分となり結露し難くなり、結露水が確保できなくなる。   In Patent Document 1, since the heat dissipating part and the water generating part are placed in the blowing air passage as shown in FIG. 8, the blowing air flow is disturbed, causing a reduction in the air volume or causing noise. Further, during cooling operation, local dew may be generated due to the turbulence of the air flow, and the surroundings of the air conditioner may be contaminated. Furthermore, since the water generating part is exposed to the warm air of the heating during heating, the water generating part is insufficiently cooled and becomes difficult to condense, and it becomes impossible to secure condensed water.

特許文献２では図９のようにペルチェ素子の放熱部に放熱用のファンを備えているので、部品が余分に必要になり、装置の質量が増し、空気調和機の据付けや取扱いの時の負担が増すと共に省資源にも反する。また、これを駆動する電力も必要となり省エネにも反し、質量も増加するので燃費も悪化する。   In Patent Document 2, as shown in FIG. 9, since the heat dissipation part of the Peltier element is provided with a heat dissipation fan, extra parts are required, the mass of the device increases, and the burden of installing and handling the air conditioner Contrary to resource conservation as the number increases. Moreover, the electric power which drives this is also required, and it is contrary to energy saving, and since the mass increases, the fuel consumption also deteriorates.

また、図８のように放熱部，水生成部を吹出し風路に置くので、特許文献１と同様に、種々の不都合な点がある。   Moreover, since the heat radiating part and the water generating part are placed in the blowing air passage as shown in FIG.

特許文献３〜６では同様に、ペルチェ素子の放熱部，吸熱部に専用のファンを備えているので、電動機などの部品が必要で、装置の質量が増し、装置の据付けや取扱いの時の負担が増す。また、これを駆動する電力も必要となる。   Similarly, in Patent Documents 3 to 6, since a dedicated fan is provided for the heat dissipation part and the heat absorption part of the Peltier element, parts such as an electric motor are required, the mass of the apparatus increases, and the burden during installation and handling of the apparatus Increase. Moreover, the electric power which drives this is also needed.

A water generating unit that generates water, a Peltier element that constitutes the water generating unit, has a cooling surface disposed in the low temperature part and a heat radiating surface disposed in the high temperature part, and condenses moisture in the air, and the water generating unit Outside the main flow path that forms the main airflow, the main flow path that forms the main airflow that flows from the air inlet to the outlet through the operation of the blower fan, A secondary airflow is formed from the first opening for air inflow formed at a position below the heat radiating surface to the second opening formed at the air channel wall of the main flow path and above the heat radiating surface. A sub-flow path, and a heat sink and a cooling surface provided on the heat dissipation surface of the Peltier element A cooling plate that is placed in this order in the sub-passage forming the secondary airflow.

上記水生成部４４０は、ペルチェ効果を利用して空気から水分を凝縮させる方式である。ペルチェ素子４４１の低温部４４２に冷却板４２５を、高温部４４４に放熱板３３８を取付けている。冷却板４２５は、図３及び図６に図示のとおり、ペルチェ素子４４１の低温部４４２に電気絶縁シート４４３を挟んで密着させ、周囲の空気中の水分を冷却して凝縮させる。水生成部４４０は、上記構成部材で構成されている。   The water generation unit 440 is a method of condensing moisture from air using the Peltier effect. A cooling plate 425 is attached to the low temperature part 442 of the Peltier element 441, and a heat sink 338 is attached to the high temperature part 444. As shown in FIGS. 3 and 6, the cooling plate 425 is brought into close contact with the low temperature portion 442 of the Peltier element 441 with the electric insulating sheet 443 interposed therebetween, and cools and condenses moisture in the surrounding air. The water generation part 440 is comprised by the said structural member.

冷却板４２５の下方には、図６に図示のとおり空間を介して吸水性水搬送部材４２３が設けられ、冷却板４２５の表面に結露した結露水が滴下したのを受けて保持する。吸水性水搬送部材４２３は、結露した水が毛細管現象で移動するように多孔質や繊維質の素材で構成されている。吸水性水搬送部材４２３には、適所に穴を設けており、この穴に前記の霧化電極４２２の導水部４２２ｂ端部を挿入する。これにより、吸水性水搬送部材４２３に保持された水分が、毛細管現象で導水部４２２ｂを通して霧化部４２２ａに供給される。冷却板４２５の表面に結露した水を受けて保持する。上記吸水性水搬送部材４２３と霧化電極４２２の導水部４２２ｂが、結露水を前記霧化部４２２ａに導く導水経路を構成する。   Under the cooling plate 425, a water-absorbing water transport member 423 is provided through a space as shown in FIG. 6, and the condensed water condensed on the surface of the cooling plate 425 is received and held.

The water-absorbing water transport member 423 and the water guiding part 422b of the atomizing electrode 422 constitute a water guiding path that guides condensed water to the atomizing part 422a.

冷却板４２５の面は、冷却空間４２５ｃに面すると共に鉛直方向に平行に設けられている。冷却空間４２５ｃは、背部を開口した冷却空間開口４２５ｄを形成するように、下方を結露水受け部材４４７、上部および冷却板４２５の対面を露受皿３５の底部の凹所、前部を集塵ボックス収納部２８１ｅなどで覆っている。但し、冷却空間開口４２５ｄだけでは空気の流れが殆どなくなってしまい、結露水が不足するため、下方に気流を確保できる隙間を設けている。下方以外にも、組立てを容易にするための隙間が形成されているが、背面及び下方に較べれば隙間寸法は小さい。特に、冷却板４２５の上方の隙間は小さくしている。   The surface of the cooling plate 425 faces the cooling space 425c and is provided parallel to the vertical direction. The cooling space 425c has a dew condensation water receiving member 447 at the bottom, a concavity at the top and the cooling plate 425 at the bottom of the dew tray 35, and a dust collecting box at the front to form a cooling space opening 425d with a back opening. Covered with a storage portion 281e or the like. However, since only the cooling space opening 425d eliminates the flow of air and condensate water is insufficient, a gap that can secure an airflow is provided below. In addition to the lower side, a gap for facilitating the assembly is formed, but the gap size is small as compared with the back side and the lower side. In particular, the gap above the cooling plate 425 is made small.

送風ファン３１１を駆動すると共に、静電霧化装置４２を運転する場合は、高電圧発生装置４５０により負の高電圧を霧化電極４２２及びイオン電極４２８に印加する。   When the blower fan 311 is driven and the electrostatic atomizer 42 is operated, a negative high voltage is applied to the atomization electrode 422 and the ion electrode 428 by the high voltage generator 450.

このとき、イオン電極４２８から周辺の空気にむけてコロナ放電が起こり、電子が放出され、イオンが発生する。また、霧化電極４２２からは帯電した微細粒の水が放出され、このイオンおよび帯電した微細粒の水が吹出し風路２９０に放出され、吹出し気流に乗って室内に吹出され、室内空気の質を向上させるなどの効果を発揮する。   At this time, corona discharge occurs from the ion electrode 428 toward the surrounding air, electrons are emitted, and ions are generated. The atomized electrode 422 discharges charged fine-grained water, and the ions and charged fine-grained water are discharged to the blowout air passage 290 and are blown into the room by the blown airflow. The effect such as improving is demonstrated.

このとき、図２，図３に図示のように送風ファン３１１の運転により吸込み口２７から吹出し口２９に流れる主気流に誘引されて、ペルチェ素子４４１周辺の空気に連通する筐体２０の背面下部に設けた背面開口２７ａから、主気流のファン上流の風路壁に形成された風路壁開口２７ｃへの副気流が生じる。この副気流とペルチェ素子４４１の放熱板３３８の放熱によって生じた上昇気流との合成気流によって、ペルチェ素子４４１の周りに副気流の一部を構成する気流が形成される。この副気流によって、ペルチェ素子４４１の高温部４４４から放熱が行われる。放熱により温度の上昇した副気流は主気流の風路壁に形成された風路壁開口２７ｃを通って主気流に合流し、吹出し口２９から室内に吹出される。この時、ペルチェ素子４４１からの放熱を良くするため、高温部４４４に取付けた放熱板３３８に放熱フィン３３８ａを設けている。この放熱フィン３３８ａの長寸方向を鉛直方向に略平行に設けて、ペルチェ素子４４１からの放熱を受けて上昇する副気流の流れをより加速している。このようにすると少ないスペースであっても、効果的な放熱が行われるようになる。   At this time, as shown in FIGS. 2 and 3, the lower portion of the rear surface of the casing 20 that communicates with the air around the Peltier element 441 is attracted by the main airflow flowing from the inlet 27 to the outlet 29 by the operation of the blower fan 311. A side airflow is generated from the rear opening 27a provided in the airflow to the air passage wall opening 27c formed in the air passage wall upstream of the main airflow fan. A combined airflow of the auxiliary airflow and the rising airflow generated by the heat dissipation of the heat dissipation plate 338 of the Peltier element 441 forms an airflow that forms a part of the auxiliary airflow around the Peltier element 441. Heat is released from the high temperature portion 444 of the Peltier element 441 by the sub airflow. The auxiliary airflow whose temperature has increased due to heat dissipation passes through the airway wall opening 27c formed in the airway wall of the main airflow, merges with the main airflow, and is blown into the room through the air outlet 29. At this time, in order to improve the heat radiation from the Peltier element 441, the heat radiation fins 338a are provided on the heat radiation plate 338 attached to the high temperature portion 444. The longitudinal direction of the radiating fins 338a is provided substantially in parallel with the vertical direction, and the flow of the auxiliary air flow rising due to the heat radiation from the Peltier element 441 is further accelerated. In this way, effective heat dissipation is performed even in a small space.

図３から図９において白抜き矢印は、吸込み口２７若しくは筐体背面開口２７ａから流入した空気の流れを示し、破線矢印及び実践矢印は、静電霧化装置４２の水生成部４４０によって形成される気流の流れを示す。   In FIG. 3 to FIG. 9, white arrows indicate the flow of air flowing in from the suction port 27 or the case back opening 27 a, and the broken line arrows and the practice arrows are formed by the water generation unit 440 of the electrostatic atomizer 42. Shows the flow of airflow.

また、ペルチェ素子４４１への通電により、ペルチェ素子４４１の低温部４４２が低温になり、冷却板４２５が冷却される。この温度が冷却空間４２５ｃの露点温度より下がると、冷却空間４２５ｃの空気中の水分が冷却板４２５の表面に結露してくる。この冷却板４２５により冷却された冷却空間４２５ｃ内の空気は重くなり、図３，図４，図７，図９の矢印で図示のように冷却板４２５に沿って下降流が生ずる。この下降流により、上記放熱フィン３３８ａの下部背面側で暖められた空気の一部が冷却空間開口４２５ｄから冷却空間４２５ｃ内に流入する。   Further, the energization of the Peltier element 441 causes the low temperature portion 442 of the Peltier element 441 to become a low temperature, and the cooling plate 425 is cooled. When this temperature falls below the dew point temperature of the cooling space 425c, moisture in the air of the cooling space 425c is condensed on the surface of the cooling plate 425. The air in the cooling space 425c cooled by the cooling plate 425 becomes heavier, and a downward flow is generated along the cooling plate 425 as shown by the arrows in FIGS. 3, 4, 7, and 9. Due to this downward flow, a part of the air warmed on the lower back side of the radiating fin 338a flows into the cooling space 425c from the cooling space opening 425d.

前記放熱フィン３３８ａの下部背面側で暖められた空気がそのまま上昇しないように、筐体２０の背面下部に設けた背面開口２７ａの上部部分を、図４，図７に図示のように放熱フィン３３８ａの下部背面の空気に露出する面の直ぐ上で暖気の上昇を妨げる構造にして冷却空間４２５ｃに流入するようにしている。   The upper portion of the back opening 27a provided in the lower back of the housing 20 is arranged so that the air heated on the lower back side of the heat radiating fin 338a does not rise as it is, as shown in FIGS. The structure is configured to prevent the rise of warm air just above the surface exposed to the air on the lower back surface of the lower portion, and to flow into the cooling space 425c.

また、下降流により、冷却板４２５の下部に流下した冷えた空気は、図３，図４，図７，図９の矢印で図示のように、結露水受け部材４４７と他の部品との隙間を通って冷却空間４２５ｃの下方外部に流出し、上記放熱フィン３３８ａ内を上昇する副気流に誘引されて合流し、風路壁開口２７ｃへ流れていく。   Further, the cooled air that has flowed down to the lower portion of the cooling plate 425 due to the downward flow is a gap between the dew condensation water receiving member 447 and other components as illustrated by arrows in FIGS. 3, 4, 7, and 9. It flows out to the lower outside of the cooling space 425c, is attracted by the auxiliary airflow rising inside the heat radiating fin 338a, merges, and flows to the air passage wall opening 27c.

また、上記冷却板４２５により冷却された冷却空間４２５ｃ内の空気が下降流を生ずると、上記放熱フィン３３８ａの下部背面側で暖められた空気の一部が冷却空間開口４２５ｄから冷却空間４２５ｃ内に流入するので、温度差が大きく、空気流が少なくても結露する量が多くなり、室内空気の温度及び湿度が低いときでも充分な結露量を確保することができる。冷却空間４２５ｃ内に流入する空気の流量が多すぎると、冷却板４２５の温度が露点温度以下に冷却できなくなるので、空気流量は少なく、上記のように放熱フィン３３８ａの下部背面側で暖められた空気のように適度に高い温度の空気が流入するのが好ましい。   Further, when the air in the cooling space 425c cooled by the cooling plate 425 generates a downward flow, a part of the air warmed on the lower back side of the radiating fin 338a enters the cooling space 425c from the cooling space opening 425d. Since the air flows in, the amount of condensation increases even if the temperature difference is large and the air flow is small, and a sufficient amount of condensation can be ensured even when the temperature and humidity of the indoor air are low. If the flow rate of the air flowing into the cooling space 425c is too large, the temperature of the cooling plate 425 cannot be cooled below the dew point temperature, so the air flow rate is small, and it is warmed on the lower back side of the radiating fin 338a as described above. It is preferable that air having a moderately high temperature such as air flows in.

このような構造にしたことによって、空気中の水分が冷却板４２５に移動して、結露が連続的に起こって、水の供給が充分確保できる。上記結露した水は次第に大きくなり、鉛直方向に平行に設けた冷却板４２５の表面を流下し、下端の冷却板屈曲部４２５ａから下方に設けた吸水性水搬送部材４２３に滴下する。滴下した水滴は吸水性水搬送部材４２３に吸収され、毛細管現象で霧化電極４２２の導水部４２２ｂに達し、霧化部４２２ａに送られる。霧化電極４２２に高電圧発生装置４５０から高電圧が印加されると、霧化部４２２ａから帯電した微細粒の水が霧化して気流により室内空間に吹出される。霧化した帯電微細粒の水は、気流に乗って室内に充満して、前述のように室内の空気や壁，カーテン，家具等の臭気成分に脱臭効果を発揮する。   By adopting such a structure, moisture in the air moves to the cooling plate 425, condensation occurs continuously, and sufficient supply of water can be ensured. The condensed water gradually increases, flows down the surface of the cooling plate 425 provided in parallel with the vertical direction, and drops from the cooling plate bent portion 425a at the lower end to the water-absorbing water transport member 423 provided below. The dropped water droplets are absorbed by the water-absorbing water conveyance member 423, reach the water guide part 422b of the atomizing electrode 422 by a capillary phenomenon, and are sent to the atomizing part 422a. When a high voltage is applied to the atomizing electrode 422 from the high voltage generator 450, the fine water particles charged from the atomizing section 422a are atomized and blown out into the indoor space by the airflow. The atomized water of charged fine particles rides on the air current and fills the room, and as described above, exerts a deodorizing effect on the indoor air and odor components such as walls, curtains and furniture.

このように、送風ファン３１１の運転によって筐体２０背面下部の背面開口２７ａを通り、主気流の風路壁に形成された風路壁開口２７ｃに流れる副気流が生じる。このため、放熱板３３８が副気流で冷却され、冷却板４２５を確実に周辺の空気の露点温度以下に制御することができる。   In this way, by the operation of the blower fan 311, a secondary airflow that flows through the rear opening 27 a at the lower back of the housing 20 and flows to the air passage wall opening 27 c formed in the air passage wall of the main airflow is generated. For this reason, the heat radiating plate 338 is cooled by the auxiliary airflow, and the cooling plate 425 can be reliably controlled to be equal to or lower than the dew point temperature of the surrounding air.

また、上記冷却板４２５により冷却された冷却空間４２５ｃ内の空気が下降流を生ずると、図４，図７，図８，図９に矢印で図示のように上記放熱フィン３３８ａの下部背面側で暖められた空気の一部が冷却空間開口４２５ｄから冷却空間４２５ｃ内に流入するので、温度差が大きく、空気流が少なくても結露する量が多くなり、室内空気の温度及び湿度が低いときでも充分な結露量を確保できる。   In addition, when the air in the cooling space 425c cooled by the cooling plate 425 causes a downward flow, as shown by arrows in FIGS. 4, 7, 8, and 9, the lower back side of the radiating fin 338a is shown. Since a part of the warmed air flows into the cooling space 425c from the cooling space opening 425d, the temperature difference is large, the amount of condensation increases even if the air flow is small, and even when the temperature and humidity of the indoor air are low Sufficient condensation can be secured.

但し、冷却空間開口４２５ｄ寸法が大きすぎると、冷却空間４２５ｃ外の空気が冷却空間４２５ｃ内への流入が過剰になって、冷却板４２５の温度が上昇して、露点温度以下に冷却できなくなり、結露が進まなくなる。更には、冷却板４２５の上方に流れる気流を形成してしまう構成であると、例えば冷却空間４２５ｃの上部に大きな開口があると、風路壁開口２７ｃに向かって直接上昇する流量の大きな気流が生じてしまうため、冷却板４２５の上方に流れる流路が形成されないようにしなければならない。   However, if the size of the cooling space opening 425d is too large, the air outside the cooling space 425c excessively flows into the cooling space 425c, the temperature of the cooling plate 425 rises, and cannot be cooled below the dew point temperature, Condensation will not progress. Furthermore, if the airflow that flows above the cooling plate 425 is formed, for example, if there is a large opening at the top of the cooling space 425c, a large airflow that rises directly toward the air passage wall opening 27c is generated. Therefore, it is necessary to prevent the flow path flowing above the cooling plate 425 from being formed.

しかし、最近は多機能でありながら小型化のニーズが、より一層求められている。このため、多くの部品を小さなスペースに組込まなければならず、複雑な部品形状になっており、組立てる為の部品間の隙間寸法を従来より大きくすることが必要になってきている。このため、風路壁開口２７ｃに近く、最も影響の大きい冷却板４２５の上方の隙間寸法を小さくする為、庇状の開口制限部材４２５ｂを設け、結露の量に大きな影響の生じないように、その大きさを実験で確かめながら極力大きくするように決定する。これによって、結露の量に大きな影響を生じることなく且つ、組立性を犠牲にすることを抑制できる。   Recently, however, there is a further demand for downsizing while being multifunctional. For this reason, many parts must be assembled in a small space, resulting in a complicated part shape, and it has become necessary to increase the gap between parts for assembly. For this reason, in order to reduce the gap size above the cooling plate 425 that is close to the air passage wall opening 27c and has the largest influence, a bowl-shaped opening limiting member 425b is provided so that the amount of condensation is not greatly affected. Determine the size as much as possible while confirming it by experiment. As a result, it is possible to suppress sacrificing assembling without significantly affecting the amount of condensation.

次に、実施例の自動清掃装置について図４，図５，図１０を用いて説明する。図１０は同室内機の清掃装置の斜視図である。   Next, the automatic cleaning apparatus of an Example is demonstrated using FIG.4, FIG.5, FIG.10. FIG. 10 is a perspective view of the cleaning device for the indoor unit.

室内熱交換器３３の上流側に上面空気吸込み部２３０及び前面空気吸込み口２３０′が形成されている。上面空気吸込み部２３０は略水平に配置され、前面空気吸込み口２３０′は鉛直方向に略平行に配置され、これらは室内機２の直交する二面を構成している。上面空気吸込み部２３０及び前面空気吸込み口２３０′に平面状のフィルター２３１，２３１′を設けている。フィルター２３１，２３１′は案内枠２３４に係着されている。案内枠２３４は、上面後部と前面下部にレール２３５，２３５′を備え、フィルター２３１，２３１′の交叉部に推進軸２４３を備えている。   A top air suction portion 230 and a front air suction port 230 ′ are formed on the upstream side of the indoor heat exchanger 33. The upper surface air suction part 230 is disposed substantially horizontally, and the front air suction port 230 ′ is disposed substantially parallel to the vertical direction, and these form two orthogonal surfaces of the indoor unit 2. Planar filters 231 and 231 ′ are provided at the upper air inlet 230 and the front air inlet 230 ′. The filters 231 and 231 ′ are engaged with the guide frame 234. The guide frame 234 includes rails 235 and 235 ′ at the upper rear portion and lower front portion, and a propulsion shaft 243 at the intersection of the filters 231 and 231 ′.

なお、同一の機能を有する部分が上面フィルター２３１用と、前面フィルター２３１′用にある場合は、前面フィルター２３１′用の部分に上面フィルター２３１用の部分の符号に「′」をつけて区別する。   In addition, when the part having the same function is for the upper filter 231 and the front filter 231 ′, the part for the front filter 231 ′ is distinguished from the part for the upper filter 231 by adding “′”. .

以下、フィルター２３１，２３１′の清掃装置２４０の動作を前面のフィルター２３１′を例にとって説明する。   Hereinafter, the operation of the cleaning device 240 for the filters 231 and 231 ′ will be described using the front filter 231 ′ as an example.

フィルター２３１′を清掃するときは推進軸２４３を回転させ、キャリッジ２６１を推進軸２４３の軸方向に移動させ、キャリッジ２６１に固定した刷毛支持枠２６２′を介して、刷毛支持枠２６２′に取付けられた軟毛の掃除用刷毛２６７′でフィルター２３１′の全面を掃く。フィルター２３１′上の塵埃を掃きとった掃除用刷毛２６７′は更に左方向に移動し、塵埃を除塵ブラシ２７０′に擦り付ける。   When cleaning the filter 231 ′, the propulsion shaft 243 is rotated, the carriage 261 is moved in the axial direction of the propulsion shaft 243, and the filter 231 ′ is attached to the brush support frame 262 ′ via the brush support frame 262 ′ fixed to the carriage 261. The entire surface of the filter 231 'is swept with a soft cleaning brush 267'. The cleaning brush 267 'that has swept the dust on the filter 231' moves further leftward and rubs the dust against the dust removing brush 270 '.

このように、フィルター２３１′上の塵埃は掃除用刷毛２６７′で掃き寄せられ、左端の除塵ブラシ２７０′に達し、除塵ブラシ２７０′で掻き取られ、除去塵埃ホッパー２８１から集塵ボックス２８４に滴下して集塵される。こうして、塵埃は、集塵ボックス２８４に集塵され外部に戻ることはない。   In this way, the dust on the filter 231 ′ is swept away by the cleaning brush 267 ′, reaches the dust removing brush 270 ′ at the left end, is scraped off by the dust removing brush 270 ′, and drops from the removed dust hopper 281 to the dust collecting box 284. And collected. Thus, dust is collected in the dust collection box 284 and does not return to the outside.

このとき、清掃動作の開始を、予め定めたフィルター清掃動作の条件、例えば、送風ファン３１１の累計運転時間が前回の清掃実行時から３０時間を超え、且つ、直前の運転で送風ファン３１１の運転が１０分以上である等の条件を満たしていれば、清掃動作を開始する。   At this time, the start of the cleaning operation is determined based on a predetermined filter cleaning operation condition, for example, the cumulative operation time of the blower fan 311 exceeds 30 hours from the previous cleaning execution, and the operation of the blower fan 311 is performed immediately before. If the condition such as is 10 minutes or longer is satisfied, the cleaning operation is started.

このように制御することにより、フィルター２３１′が常に塵埃の少ない状態に保たれるので、フィルター２３１′の汚れに起因する熱交換器３３の性能低下を防ぎ、かつ、吹出し空気を清潔に保つことができる。また、静電霧化装置４２で発生させた帯電した微細粒の水を横流ファンの整流された気流に乗せて室内の遠方まで運搬し、帯電した微細粒の水の脱臭作用を室内の広範囲で発現させることができる。   By controlling in this way, the filter 231 'is always kept in a dust-free state, so that the performance deterioration of the heat exchanger 33 due to the dirt of the filter 231' is prevented and the blown air is kept clean. Can do. In addition, the charged fine-grained water generated by the electrostatic atomizer 42 is carried on a rectified air flow of a cross-flow fan to the far end of the room, and the deodorizing action of the charged fine-grained water is spread over a wide range in the room. Can be expressed.

集塵ボックス２８４内の塵埃を捨てる場合は、集塵ボックス２８４を外し、内部の塵埃を掻き出す。   When throwing away the dust in the dust collection box 284, the dust collection box 284 is removed and the dust inside is scraped.

このような、フィルターの自動清掃装置２４０を備えることにより、静電霧化装置４２による空気質の改善と相俟って、室内を快適に、清潔に保つことができる。   By providing such an automatic cleaning device 240 for the filter, it is possible to keep the room comfortable and clean, coupled with the improvement of air quality by the electrostatic atomizer 42.

このように、実施例の空気調和機１は、熱交換器に室内空気を送風する送風ファン３１１と、静電霧化装置と、該静電霧化装置へ供給する霧化用水を生成する水生成部４４０と、該水生成部４４０に内蔵され、空気中の水分を結露させる冷却板４２５を冷却するペルチェ素子と、該水生成部４４０で得られる結露水を前記霧化電極４２２ａに導く導水経路とを備え、前記送風ファン３１１の運転により吸込み口から吹出し口に流れる主気流と、該吹出し口の前記ペルチェ素子４４１側の端部（前記主気流の風路壁）から空気調和機１の筐体２０端部までの間の筐体２０背面下部に設けた開口２７ａを入口とし、前記主気流の風路壁の上部に形成された開口２７ｃを出口とする流路を形成する副気流を生ぜしめ、該副気流の流路中に前記ペルチェ素子４４１の高温部４４４に取付けられた放熱板３３８を位置させると共に、該副気流に臨んで上下に長い冷却空間開口４２５ｄを有する冷却空間４２５ｃを形成し、該冷却空間４２５ｃに面して前記冷却板４２５を鉛直方向に平行に設ける。   As described above, the air conditioner 1 according to the embodiment includes the blower fan 311 that blows indoor air to the heat exchanger, the electrostatic atomizer, and the water that generates the atomization water to be supplied to the electrostatic atomizer. A generation unit 440, a Peltier element that cools a cooling plate 425 that is built in the water generation unit 440 and condenses moisture in the air, and a water guide that guides the condensed water obtained by the water generation unit 440 to the atomization electrode 422a. A main airflow that flows from the suction port to the blowout port by the operation of the blower fan 311, and an end of the blowout port on the Peltier element 441 side (the airflow path wall of the main airflow) of the air conditioner 1. A side airflow that forms a flow path having an opening 27a provided in the lower part of the back surface of the case 20 up to the end of the case 20 as an inlet and an opening 27c formed in the upper part of the air flow wall of the main airflow as an outlet. Generated in the flow path of the side airflow. A heat radiating plate 338 attached to the high temperature portion 444 of the element 441 is positioned, and a cooling space 425c having a cooling space opening 425d that is vertically long facing the auxiliary airflow is formed, facing the cooling space 425c, and the cooling A plate 425 is provided parallel to the vertical direction.

一般に、静電霧化で微細粒の水を帯電させて室内に浮遊させると、その電荷によりラジカルが生じるなどして脱臭作用を示すことが知られている。このとき、静電霧化させる水の量が極めて僅かでも、ナノレベルの微細粒の水のため、その個数は膨大になり、脱臭効果が現れる。   In general, it is known that when fine water particles are charged by electrostatic atomization and floated in a room, radicals are generated by the charges, thereby exhibiting a deodorizing action. At this time, even if the amount of water to be electrostatically atomized is very small, the number of the water becomes enormous due to nano-level fine water, and a deodorizing effect appears.

このため、静電霧化装置に供給する霧化用水の量も少なく済み、ペルチェ素子４４１の冷却板４２５に結露させるための気流の量も多くなくても良い。   For this reason, the amount of atomizing water supplied to the electrostatic atomizer is small, and the amount of airflow for causing condensation on the cooling plate 425 of the Peltier element 441 may not be large.

実施例の空気調和機１によれば、熱交換器に室内空気を送風する送風ファン３１１と、静電霧化装置と、該静電霧化装置へ供給する霧化用水を生成する水生成部４４０と、該水生成部４４０に内蔵され、空気中の水分を結露させる冷却板４２５を冷却するペルチェ素子４４１と、該水生成部４４０で得られる結露水を前記霧化電極４２２ａに導く導水経路とを備え、前記送風ファン３１１の運転により吸込み口から吹出し口に流れる主気流と、該吹出し口の前記ペルチェ素子４４１側の端部（前記主気流の風路壁）から前記空気調和機１の筐体２０の該ペルチェ素子４４１側の端部までの間の背面下方位置に設けた開口２７ａを入口とし、前記主気流の風路壁の上方位置に形成された開口２７ｃを出口とする流路を形成する副気流を生ぜしめ、該副気流の流路中に前記ペルチェ素子４４１の高温部４４４に取付けられた放熱板３３８を位置させると共に、該副気流に臨んで上下に長い冷却空間開口４２５ｄを有する冷却空間４２５ｃを形成し、該冷却空間４２５ｃに面して前記冷却板４２５の面を鉛直方向に平行に設ける。   According to the air conditioner 1 of an Example, the ventilation fan 311 which ventilates room air to a heat exchanger, the electrostatic atomizer, and the water production | generation part which produces | generates the water for atomization supplied to this electrostatic atomizer 440, a Peltier element 441 that cools a cooling plate 425 that is built in the water generation unit 440 and condenses moisture in the air, and a water guide path that guides the condensed water obtained by the water generation unit 440 to the atomization electrode 422a. Of the air conditioner 1 from the main airflow flowing from the suction port to the blowout port by the operation of the blower fan 311 and the end of the blowout port on the Peltier element 441 side (the airflow path wall of the main airflow). A flow path having an opening 27a provided at a lower position on the back side of the casing 20 up to the end on the Peltier element 441 side as an inlet and an opening 27c formed at an upper position of the air flow wall of the main airflow as an outlet. Give rise to side airflow that forms A heat sink 338 attached to the high temperature portion 444 of the Peltier element 441 is positioned in the flow path of the secondary airflow, and a cooling space 425c having a cooling space opening 425d that is vertically long facing the secondary airflow is formed. Facing the cooling space 425c, the surface of the cooling plate 425 is provided parallel to the vertical direction.

これにより、ペルチェ素子４４１によって、冷却板４２５が冷やされ、冷却板４２５付近の空気中の水分が冷却板４２５に凝縮し、結露が生ずる。この冷却板４２５付近の空気は冷やされて重くなり、冷却板４２５に沿って下降流が生ずる。下降流により、空気が薄くなった冷却板４２５の上部には、それを埋めるように、冷却空間４２５ｃの空気が流入する。また、下降気流により、冷却板４２５の下部に溜った冷えた空気は、結露水受け部材４４７に遮られて、冷却空間の壁に沿って上昇し、冷却空間４２５ｃに自然対流が起きる。冷却空間開口４２５ｄ付近では冷却空間４２５ｃの自然対流と冷却空間４２５ｃ外の副気流が混じりあい、内外の気流の間で温度，湿度の交換が行われる。   As a result, the cooling plate 425 is cooled by the Peltier element 441, moisture in the air near the cooling plate 425 is condensed in the cooling plate 425, and condensation occurs. The air in the vicinity of the cooling plate 425 is cooled and becomes heavy, and a downward flow is generated along the cooling plate 425. The air in the cooling space 425c flows into the upper portion of the cooling plate 425 where the air has become thinner due to the downward flow so as to fill it. Further, the cooled air accumulated in the lower portion of the cooling plate 425 by the descending airflow is blocked by the dew condensation water receiving member 447 and rises along the wall of the cooling space, and natural convection occurs in the cooling space 425c. In the vicinity of the cooling space opening 425d, the natural convection in the cooling space 425c and the auxiliary airflow outside the cooling space 425c mix, and the temperature and humidity are exchanged between the internal and external airflow.

このようにして、副気流の水分が冷却板４２５に移動し、結露が連続的に起こって、霧化用水の供給が可能になる。上記冷却空間内の自然対流する冷えた空気の一部は、冷却空間４２５ｃの空気の流入量に相当する量が結露水受け部材と隣接する部材との隙間から下降して室内機の筐体下部空間に流れ出る。この筐体下部空間に流出した冷えた空気は、空気調和機１の筐体２０の背面下方位置に設けた開口２７ａから流入した空気の一部と混ざって、放熱板３３８で加熱されて上昇気流となり、副気流の一部となる。   In this way, the water in the auxiliary airflow moves to the cooling plate 425, and condensation occurs continuously, so that the water for atomization can be supplied. A part of the chilled air that naturally convects in the cooling space descends from the gap between the condensed water receiving member and the adjacent member by an amount corresponding to the amount of air flowing into the cooling space 425c. It flows out into space. The cooled air that has flowed out into the lower space of the housing is mixed with a part of the air that flows in from the opening 27a provided at the lower position of the back surface of the housing 20 of the air conditioner 1, and is heated by the heat radiating plate 338 to rise. And becomes part of the secondary airflow.

副気流は熱交換器に室内空気を送風する送風ファン３１１の運転に伴って生ずる送風ファン３１１より上流の負圧に誘引されて引き起こされる。該吹出し口の前記ペルチェ素子４４１側の端部（前記主気流の風路壁）から空気調和機１の筐体２０の該ペルチェ素子４４１側の端部までの間の背面下方位置に設けた開口２７ａから流入した副気流は、ペルチェ素子４４１の放熱板３３８からの熱を受け、上昇気流となって上昇し、空気調和機１上部の吸込み口から送風ファン３１１までの間の開口から流出し、主気流に合流し、送風ファン３１１に吸込まれ、空気調和機１から吹出される。このとき、上記の冷却空間開口４２５ｄ付近を通る副気流は、冷却空間の自然対流と混合し、その一部が内部の自然対流と入替わる。   The secondary airflow is induced by the negative pressure upstream of the blower fan 311 generated in association with the operation of the blower fan 311 that blows room air to the heat exchanger. An opening provided at a lower position on the back side between the end of the air outlet 1 on the Peltier element 441 side (the airflow wall of the main airflow) and the end of the casing 20 of the air conditioner 1 on the Peltier element 441 side. The auxiliary airflow that flows in from 27a receives heat from the heat dissipation plate 338 of the Peltier element 441, rises as an ascending airflow, flows out from the opening between the air inlet of the upper part of the air conditioner 1 and the blower fan 311, The air flows into the main airflow, is sucked into the blower fan 311, and is blown out from the air conditioner 1. At this time, the side airflow passing through the vicinity of the cooling space opening 425d is mixed with the natural convection in the cooling space, and a part thereof is replaced with the internal natural convection.

この副気流の量は多くなく、冷却空間の自然対流の量も同様に少ない。しかし、前述のように、結露させるための気流の量も多くなくて良いので、静電霧化により脱臭の効果を得ることができる。なお、静電霧化により、微細粒の水が発生し、含まれるラジカルなどにより、臭いの原因物質を分解するなどするが、最終的には、水蒸気となって室内空気に戻るので、一見加湿の効果も有るように見えるが、もともと、霧化用水を室内空気から得ているので加湿の効果は生じない。   The amount of this side airflow is not large, and the amount of natural convection in the cooling space is also small. However, as described above, since there is no need to increase the amount of airflow for dew condensation, the effect of deodorization can be obtained by electrostatic atomization. In addition, electrostatic atomization generates fine-grained water and decomposes odor-causing substances with contained radicals, etc., but eventually it returns to room air as water vapor. However, since the atomization water is originally obtained from room air, the humidification effect does not occur.

このように、空気調和用の送風ファン３１１を運転し、ペルチェ素子４４１に通電することにより、冷却空間と冷却空間外の空気を流動させるので、水生成部４４０のための専用のファンが不要となり、資源の節約および軽量化が図れる。また、水生成部４４０専用のファンを運転するためのエネルギーも不要となる。   In this way, by operating the air-conditioning blower fan 311 and energizing the Peltier element 441, the air outside the cooling space and the cooling space flows, so that a dedicated fan for the water generating unit 440 becomes unnecessary. , Resource saving and weight reduction can be achieved. In addition, energy for operating a fan dedicated to the water generation unit 440 is also unnecessary.

このため、静電霧化装置を搭載して、室内環境を快適にしつつ、省資源，軽量，省エネに適する空気調和機１を提供することができる。   For this reason, it is possible to provide an air conditioner 1 that is equipped with an electrostatic atomizer and is suitable for resource saving, light weight, and energy saving while making the indoor environment comfortable.

また、実施例の空気調和機１は、前記筐体に設けた開口の一つが背面下部に開口している。   In addition, in the air conditioner 1 of the embodiment, one of the openings provided in the casing is open at the lower back.

これにより、使用者の目に付かない背面に開口することで、外観を損なうこと無く、副気流の入口を設けることができ、ペルチェ素子４４１の放熱による上昇気流が円滑に形成される。これにより水生成部４４０が充分冷却されて、結露が順調に進む。   Thereby, by opening in the back surface which a user cannot see, the entrance of a subairflow can be provided without impairing an external appearance, and the updraft by heat dissipation of the Peltier device 441 is formed smoothly. Thereby, the water production | generation part 440 is fully cooled and dew condensation progresses smoothly.

このため、外観を損なうこと無く、霧化用水の供給が確実に行われる空気調和機１を提供することができる。   For this reason, the air conditioner 1 in which the atomization water is reliably supplied without deteriorating the appearance can be provided.

また、実施例の空気調和機１は、前記風路壁に形成された開口２７ｃがフィルターと熱交換器の間の風路に開口している。   In the air conditioner 1 of the embodiment, the opening 27c formed in the air passage wall opens in the air passage between the filter and the heat exchanger.

これにより、使用者の目に付かない内部に開口することで、外観を損なうこと無く、副気流の出口を設けることができ、上述と同様に、霧化用水の供給が確実に行われる空気調和機１を提供することができる。   Thus, by opening inside the user's eyes, an airflow outlet can be provided without impairing the appearance, and the atomization water can be reliably supplied in the same manner as described above. Machine 1 can be provided.

また、実施例の空気調和機１は、前記放熱板３３８に放熱フィンを備え、放熱フィンの長寸方向を鉛直方向に略平行にする。   Moreover, the air conditioner 1 of an Example equips the said heat sink 338 with a heat sink, and makes the longitudinal direction of a heat sink fin substantially parallel to a perpendicular direction.

これにより、副気流の生成が、送風ファン３１１の運転に伴う誘引力およびペルチェ素子４４１の放熱板３３８からの放熱に伴う気流の熱膨張による上昇力によって生ずる。この副気流が放熱フィン３３８ａに沿ってスムーズに上方に流れ、放熱が円滑に行われる。   As a result, the generation of the auxiliary airflow is caused by the attraction force accompanying the operation of the blower fan 311 and the rising force due to the thermal expansion of the airflow accompanying the heat dissipation from the heat dissipation plate 338 of the Peltier element 441. This sub-airflow smoothly flows upward along the radiation fins 338a, and the heat radiation is performed smoothly.

このため、放熱板３３８の冷却が効率良く行われ、水生成部４４０が十分冷却されて、結露が順調に進み、霧化用水の供給が確実に行われる空気調和機１を提供することができる。   Therefore, it is possible to provide the air conditioner 1 in which the cooling plate 338 is efficiently cooled, the water generation unit 440 is sufficiently cooled, the dew condensation proceeds smoothly, and the atomization water is reliably supplied. .

また、実施例の空気調和機１は、前記水生成部４４０の上方に、庇状の開口制限部材４２５ｂを設けた。   Moreover, the air conditioner 1 of the Example provided the bowl-shaped opening limiting member 425b above the water generation part 440.

一般に、ペルチェ素子４４１の冷却板４２５の温度は放熱板３３８での放熱の良否と冷却板４２５が受ける熱負荷の大小によって定まる。放熱の良否と熱負荷の大小は熱交換部を流れる気流の単時間あたりの量と、気流と熱交換部との温湿度の差によって定まる。   In general, the temperature of the cooling plate 425 of the Peltier element 441 is determined by the quality of heat radiation at the heat radiating plate 338 and the magnitude of the thermal load received by the cooling plate 425. The quality of heat radiation and the magnitude of the heat load are determined by the amount of airflow flowing through the heat exchange section per hour and the difference in temperature and humidity between the airflow and the heat exchange section.

冷却板４２５周囲の空気中の水分を結露させる場合、冷却板４２５の温度を露点温度以下にする必要がある。実施例の場合、熱交換部に入る気流の温度は室内空気の温度とほぼ等しく、調整することはできない。また、放熱板３３８を流れる気流は多いほうが放熱が良好になって、冷却板４２５の温度を下げるのに効果があるが、冷却板４２５を流れる気流は多すぎると、冷却板４２５の熱負荷が大きくなり過ぎて冷却板４２５の温度が上がり、露点温度を超えて結露が生じなくなる。逆に、冷却板４２５を流れる気流が少なすぎると、結露は生じるものの結露の絶対量が少なくなり、十分な量の霧化用水を供給できなくなる。   When moisture in the air around the cooling plate 425 is condensed, the temperature of the cooling plate 425 needs to be equal to or lower than the dew point temperature. In the case of the embodiment, the temperature of the airflow entering the heat exchange section is almost equal to the temperature of the room air and cannot be adjusted. Also, the more the airflow flowing through the heat sink 338, the better the heat dissipation, which is effective for lowering the temperature of the cooling plate 425. However, if there is too much airflow flowing through the cooling plate 425, the heat load on the cooling plate 425 is increased. It becomes too large and the temperature of the cooling plate 425 rises, and the dew point temperature is exceeded and condensation does not occur. Conversely, if the airflow flowing through the cooling plate 425 is too small, although condensation occurs, the absolute amount of condensation decreases, and a sufficient amount of atomizing water cannot be supplied.

また、実施例の場合、冷却板４２５を流れる気流の温度，湿度は冷却板４２５での吸熱量，結露量と、冷却空間開口４２５ｄでの副気流との混合によって交換される熱量，水分量とのバランスによって決まり、交換される熱量，水分量は冷却空間開口４２５ｄの形状、開口面積によって増減する。送風ファン３１１の運転や、放熱板３３８による自然対流によって生ずる副気流が変化すると冷却板４２５での結露の量が変化することが実験により確認されている。このため、放熱板３３８に流れる気流は十分な量を確保して、冷却板４２５に流れる気流と副気流との混合量を適正にする工夫が必要になる。   Further, in the case of the embodiment, the temperature and humidity of the airflow flowing through the cooling plate 425 are the amount of heat and moisture exchanged by mixing the heat absorption amount and dew condensation amount at the cooling plate 425 and the auxiliary airflow at the cooling space opening 425d. The amount of heat and the amount of water to be exchanged vary depending on the shape and opening area of the cooling space opening 425d. It has been confirmed by experiments that the amount of dew condensation on the cooling plate 425 changes when the side airflow generated by the operation of the blower fan 311 or natural convection by the heat radiating plate 338 changes. For this reason, the device which secures sufficient quantity of the airflow which flows into the heat sink 338, and makes the mixing amount of the airflow and sub-airflow which flows into the cooling plate 425 appropriate is needed.

実施例の空気調和機１によれば、前記水生成部４４０の上方に、庇状の開口制限部材４２５ｂを設ける。   According to the air conditioner 1 of the embodiment, the bowl-shaped opening limiting member 425b is provided above the water generating unit 440.

これにより、冷却板４２５を流れる気流と副気流との混合による温湿度の交換が適正な範囲になるように、開口制限部材４２５ｂの大きさを変えて実験し、効果を確かめながら、開口制限部材４２５ｂの大きさを決定することができる。この開口制限部材４２５ｂの大きさは、水生成部４４０の上方隙間を小さくなるように極力大きくしている。但し、この開口制限部材４２５ｂの大きさは、隣接する部材との隙間寸法を組立て性も考慮して決める必要がある。   Thus, the opening limiting member is tested while changing the size of the opening limiting member 425b so that the exchange of temperature and humidity by mixing the airflow flowing through the cooling plate 425 and the auxiliary airflow is within an appropriate range, and confirming the effect. The size of 425b can be determined. The size of the opening limiting member 425b is increased as much as possible so as to reduce the upper gap of the water generating unit 440. However, the size of the opening limiting member 425b needs to be determined in consideration of the assemblability of the gap between adjacent members.

このように開口制限部材４２５ｂを設けることにより、冷却板４２５の温度を露点温度以下になるようにすることができる。このため、水生成部４４０で霧化用水を確実に生成できる空気調和機１を提供することができる。   By providing the opening limiting member 425b as described above, the temperature of the cooling plate 425 can be made to be equal to or lower than the dew point temperature. For this reason, the air conditioner 1 which can produce | generate the water for atomization reliably in the water production | generation part 440 can be provided.

実施例２は副気流の出口の位置を実施例１の主気流の送風ファン３１１上流の風路壁に形成された開口２７ｃから、筐体２０の上面に変えたものである。具体的な位置の図示を省略するが、図１０の筐体２０の上面に設けられた除塵ブラシ２７０の左側の上面若しくは除塵ブラシ２７０と空気吸込み部２３０との間の上面に開口させるのが望ましい。   In the second embodiment, the position of the outlet of the auxiliary airflow is changed from the opening 27c formed on the air passage wall upstream of the main airflow fan 311 of the first embodiment to the upper surface of the housing 20. Although illustration of a specific position is omitted, it is desirable to open on the upper surface on the left side of the dust removing brush 270 provided on the upper surface of the housing 20 of FIG. 10 or the upper surface between the dust removing brush 270 and the air suction portion 230. .

実施例２における副気流は、ペルチェ素子４４１の駆動に伴なう高温部４４４の放熱板３３８からの放熱による上昇気流で生ずる。このため、空気調和機の熱交換器に室内空気を送風する送風ファン３１１を運転していない状態でも、静電霧化装置４２を運転し、ペルチェ素子４４１を駆動することで、帯電した微細粒の水を室内に放出し、室内の空気の質を高めることができる。   The auxiliary airflow in the second embodiment is generated by an upward airflow due to heat dissipation from the heat dissipation plate 338 of the high temperature portion 444 accompanying the driving of the Peltier element 441. For this reason, even when the blower fan 311 for blowing room air to the heat exchanger of the air conditioner is not operated, the electrostatic atomizer 42 is operated and the Peltier element 441 is driven, thereby charging the fine particles. The water in the room can be discharged to improve the quality of indoor air.

このように、実施例の空気調和機は、熱交換器に室内空気を送風する送風ファン３１１と、静電霧化装置と、該静電霧化装置へ供給する霧化用水を生成する水生成部４４０と、該水生成部４４０に内蔵され、空気中の水分を結露させる冷却板４２５を冷却するペルチェ素子４４１と、該水生成部４４０で得られる結露水を前記霧化電極４２２ａに導く導水経路と、前記送風ファン３１１の運転により吸込み口から吹出し口に流れる主気流と、前記吹出し口の前記ペルチェ素子４４１側の端部から前記空気調和機の該ペルチェ素子４４１側の端部までの間の筐体の上下にそれぞれ設けた開口とを備え、前記ペルチェ素子４４１の吸放熱用の送風機無し若しくは送風機に通電せず、前記ペルチェ素子４４１に通電することにより、主気流とは別の、前記複数の開口を流入口，流出口とする流路に副気流を生ぜしめ、該副気流の流路中に前記ペルチェ素子４４１の高温部４４４に取付けられた放熱板３３８を位置させると共に、該副気流に臨んで上下に長い冷却空間開口４２５ｄを有する冷却空間を形成し、該冷却空間に面して前記冷却板４２５の面を鉛直方向に平行に設ける。   As described above, the air conditioner according to the embodiment generates the water for generating the atomizing water to be supplied to the blower fan 311 that blows room air to the heat exchanger, the electrostatic atomizer, and the electrostatic atomizer. 440, a Peltier element 441 that cools a cooling plate 425 that condenses moisture in the air, and is built into the water generation unit 440, and water that guides condensed water obtained by the water generation unit 440 to the atomization electrode 422a. A path, a main airflow flowing from the suction port to the blowout port by the operation of the blower fan 311, and a distance from the end of the blower port on the Peltier element 441 side to the end of the air conditioner on the Peltier element 441 side The Peltier element 441 has no openings for absorbing and radiating heat or is not energized to the Peltier element 441. A secondary airflow is generated in a flow path having the plurality of openings as inlets and outlets, and a heat radiating plate 338 attached to the high temperature portion 444 of the Peltier element 441 is positioned in the flow path of the auxiliary airflow, A cooling space having a cooling space opening 425d that is vertically long facing the auxiliary airflow is formed, and the surface of the cooling plate 425 is provided parallel to the vertical direction so as to face the cooling space.

これにより、副気流はペルチェ素子４４１の駆動による放熱板３３８に生ずる上昇気流によって引き起こされる。前記吹出し口の前記ペルチェ素子４４１側の端部から空気調和機筐体の該ペルチェ素子４４１側の端部までの間の筐体下方の開口２７ａから流入した副気流の大部分は、ペルチェ素子４４１の放熱板３３８からの熱を受け、上昇気流となって上昇し、該吹出し口の端部から空気調和機筐体の端部までの間の上方に設けられた開口２７ｃから流出する。   As a result, the auxiliary airflow is caused by the rising airflow generated in the heat radiating plate 338 by driving the Peltier element 441. Most of the auxiliary airflow that flows in from the opening 27a below the casing between the end of the outlet on the Peltier element 441 side and the end of the air conditioner casing on the Peltier element 441 side is the Peltier element 441. Receiving the heat from the radiator plate 338, it rises as an updraft and flows out from the opening 27c provided between the end of the outlet and the end of the air conditioner housing.

このとき、冷却空間開口４２５ｄ付近を通る副気流は、上記の冷却空間の自然対流と混合し、その一部が内部の自然対流と入替わる。   At this time, the side airflow passing through the vicinity of the cooling space opening 425d is mixed with the natural convection in the cooling space, and a part thereof is replaced with the internal natural convection.

このように、ペルチェ素子４４１に通電することにより、冷却空間と冷却空間外の空気を流動させる副気流が生じるので、水生成部４４０のための専用のファンが不要となり、資源を節約し、軽量化が図れる。また、水生成部４４０用のファンを運転するためのエネルギーも不要となる。   In this way, when the Peltier element 441 is energized, a side airflow that causes the air outside the cooling space and the cooling space to flow is generated, so that a dedicated fan for the water generating unit 440 is unnecessary, saving resources and reducing the weight. Can be achieved. In addition, energy for operating the fan for the water generation unit 440 is also unnecessary.

また、水生成部４４０のためのファンが無いので、空気調和機が冷房，暖房，除湿，送風等の運転をしていないときでも静電霧化装置だけの運転ができ、低騒音で室内を脱臭して質の高い環境に維持することができる。   In addition, since there is no fan for the water generation unit 440, only the electrostatic atomizer can be operated even when the air conditioner is not operated for cooling, heating, dehumidification, ventilation, etc. It can be deodorized and maintained in a high quality environment.

このため、静電霧化装置を搭載して、低騒音で室内環境を快適にしつつ、省資源，軽量，省エネに適する空気調和機を提供することができる。   For this reason, it is possible to provide an air conditioner that is equipped with an electrostatic atomizer and is suitable for resource saving, light weight, and energy saving while making the indoor environment comfortable with low noise.

また、実施例の空気調和機は、前記筐体に設けた開口の一つが筐体上面に開口している。   Further, in the air conditioner of the embodiment, one of the openings provided in the casing is opened on the upper surface of the casing.

これにより、使用者の目に付かない上面に開口することで、外観を損なうこと無く、副気流の出口を設けることでき、ペルチェ素子４４１の放熱による上昇気流が円滑に形成され、水生成部４４０が十分冷却されて、結露が順調に進む。   Thus, by opening on the upper surface that is not visible to the user, it is possible to provide an outlet for the secondary airflow without impairing the appearance, and a rising airflow due to heat dissipation of the Peltier element 441 is smoothly formed, and the water generation unit 440 is provided. Is sufficiently cooled, and condensation proceeds smoothly.

このため、外観を損なうこと無く、霧化用水の供給が確実に行われる空気調和機を提供することができる。   Therefore, it is possible to provide an air conditioner that reliably supplies the atomizing water without deteriorating the appearance.

図３，図６，図９に図示の冷却板４２５の形状および大きさを変えた実施例を、図１１，図１２，図１３により説明する。   Embodiments in which the shape and size of the cooling plate 425 shown in FIGS. 3, 6, and 9 are changed will be described with reference to FIGS.

図１１，図１２は水生成部を室内機の正面から見た部分断面図で、ペルチェ素子４４１の大きさと略同じ大きさの平板形状の冷却板４２５を用いたものである。図１３も水生成部を室内機の正面から見た部分断面図で、図３，図６，図９に図示の冷却板４２５を屈曲部４２５ａのない平板形状を用いたものである。   11 and 12 are partial cross-sectional views of the water generating unit as viewed from the front of the indoor unit, and use a flat plate-like cooling plate 425 having substantially the same size as the Peltier element 441. FIG. FIG. 13 is also a partial cross-sectional view of the water generating unit as viewed from the front of the indoor unit. The cooling plate 425 shown in FIGS. 3, 6 and 9 is a flat plate without a bent part 425a.

冷却板４２５に凝縮した空気中の水分は、吸水性水搬送部材４２３，吸水性水搬送部材４２３ａなどの導水経路を経て、霧化電極４２２に供給される。霧化電極４２２の霧化部４２２ａで霧化した水分は、吹出し風路２９０の気流と共に室内に吹出される。上記吸水性水搬送部材４２３ａは、吸水性水搬送部材４２３と冷却板４２５との隙間を補って、上記冷却板４２５に凝縮した水を導水する。   Moisture in the air condensed on the cooling plate 425 is supplied to the atomizing electrode 422 through a water guide path such as the water-absorbing water transport member 423 and the water-absorbing water transport member 423a. The water atomized by the atomization part 422a of the atomization electrode 422 is blown into the room together with the air flow in the blowout air path 290. The water-absorbing water transport member 423a guides the water condensed in the cooling plate 425 by making up the gap between the water-absorbing water transport member 423 and the cooling plate 425.

冷却板４２５の大きさは、ペルチェ素子４４１の大きさに対応した略同じ位の大きさが望ましい。ペルチェ素子４４１の大きさに較べて、小さ過ぎると結露する面積が減少してしまう。大き過ぎるとペルチェ素子４４１から離れた部分で温度が露点温度まで下がらない場合が想定される。このように、冷却板４２５の大きさが大き過ぎると、必要以上にスペースを大きくとる若しくは必要以上に冷却しなければならず、消費電力を多く要することになる場合がある。これは結露条件の悪い地域或いは季節によって結露する環境が大きく変化する地域で、問題になる虞がある。ペルチェ素子４４１の大きさに較べて大きい部分が冷却板４２５の下部に位置する場合は、冷却板４２５の温度が露点温度以下の部分で結露して流下する水滴が、この下部の露点温度より高い部分に至るとスムースに流下し難くなる。   The size of the cooling plate 425 is preferably about the same size corresponding to the size of the Peltier element 441. If it is too small compared to the size of the Peltier element 441, the area where condensation occurs will decrease. If it is too large, it is assumed that the temperature does not drop to the dew point temperature at a part away from the Peltier element 441. Thus, if the size of the cooling plate 425 is too large, it may be necessary to take more space than necessary or to cool more than necessary, which may require much power consumption. This may be a problem in regions where the dew condensation conditions are bad or in regions where the dew condensation environment changes greatly depending on the season. When a portion larger than the size of the Peltier element 441 is located below the cooling plate 425, water droplets flowing down due to condensation at a portion where the temperature of the cooling plate 425 is lower than the dew point temperature are higher than the dew point temperature below this portion. When it reaches the part, it becomes difficult to flow down smoothly.

したがって、冷却板４２５の大きさがペルチェ素子４４１の大きさ（或いは冷却能力）に対応しない程に大き過ぎる場合は、結露した水滴が吸水性水搬送部材４２３ａまで流下若しくは落下するのを妨げることになる。これは、露点温度以下の部分では、結露が進行して水滴が大きくなるため、重力によりスムースに流下するが、露点温度より高い部分では結露しないため、水滴が表面張力により流下し難くなるからである。特に、図６の冷却板４２５のように、冷却板４２５の下端に屈曲部４２５ａを有するものは、結露条件の悪い地域若しくは環境下で使用する際に屈曲部４２５ａで結露せず、且つ屈曲部４２５ａの傾斜面を流下しなければならず、鉛直な面に較べて流下し難くなり、吸水性水搬送部材４２３への水の供給が不充分になる虞がある。   Therefore, when the size of the cooling plate 425 is too large to correspond to the size (or cooling capacity) of the Peltier element 441, the condensed water droplets are prevented from flowing down or falling down to the water absorbing water transport member 423a. Become. This is because in the part below the dew point temperature, condensation progresses and the water droplets become large, so it flows down smoothly due to gravity, but in the part above the dew point temperature, no condensation occurs, so it is difficult for water drops to flow down due to surface tension. is there. In particular, a cooling plate 425 having a bent portion 425a at the lower end of the cooling plate 425, such as the cooling plate 425 in FIG. 6, does not condense on the bent portion 425a when used in an area or environment where the condensation condition is bad, and the bent portion. It is necessary to flow down the inclined surface of 425a, and it is difficult to flow down compared to a vertical surface, and there is a possibility that water supply to the water-absorbing water transport member 423 becomes insufficient.

これを解消する為には、ペルチェ素子４４１の冷却熱量を多くするように印加電力を制御すればよいが、その分だけ消費電力を多く要することになる。   In order to solve this problem, the applied power may be controlled so as to increase the amount of cooling heat of the Peltier element 441. However, much power consumption is required.

図１１，図１２に示す実施例は、図６に図示の冷却板４２５下端の屈曲部４２５ａの無いものとした。これによって、ペルチェ素子４４１で直接冷却されない屈曲部４２５ａでの放熱がなくなり、実施例１に較べて結露する部分の温度が低くなり、結露量が多くなる。更には、屈曲部４２５ａ、即ち傾斜面を流下しないことから、結露した水滴がスムースに流下若しくは落下し、導水経路の一部を構成する吸水性水搬送部材４２３ａへの水の供給を容易に出来る。   The embodiment shown in FIGS. 11 and 12 has no bent portion 425a at the lower end of the cooling plate 425 shown in FIG. As a result, heat radiation at the bent portion 425a that is not directly cooled by the Peltier element 441 is eliminated, and the temperature at the portion where condensation occurs is lower than in the first embodiment, and the amount of condensation increases. Furthermore, since it does not flow down the bent portion 425a, that is, the inclined surface, the condensed water droplets smoothly flow down or falls, and water can be easily supplied to the water absorbing water transport member 423a constituting a part of the water guide path. .

また、図１２，図１３に示す実施例は、霧化ハウジング４３１に、冷却板４２５が配置された冷却空間４２５ｃと霧化部４２２ａの配置された主気流の空気吹出し口２９とを連通する通路を形成している。これにより、実線矢印のとおり空気吹出し口２９から送風される気流に誘引されて、冷却空間４２５ｃ内の空気が霧化ハウジング４３１内に流出し、空気吹出し口２９から室内に送風される。この冷却空間４２５ｃ内の空気が霧化ハウジング４３１内に流出することにより、冷却空間開口４２５ｄから水生成部４４０が収納された筐体内部空間の空気が、冷却空間４２５ｃ内に効率的に流入する。前記筐体内部空間の空気の気流は、放熱板３３８，放熱フィン３３８ａにより短時間であるが加熱される。この加熱された空気が冷却空間４２５ｃ内に流入するので、冬季などに空気調和機で暖房運転を開始直後のように、室内の壁面温度及び空気温度が低い場合でも、ペルチェ素子４４１の吸熱面側の冷却板４２５表面に結露した水分が凍結するを抑制できる。   In the embodiment shown in FIGS. 12 and 13, the atomizing housing 431 communicates with the cooling space 425c in which the cooling plate 425 is disposed and the air outlet 29 of the main airflow in which the atomizing portion 422a is disposed. Is forming. As a result, the air in the cooling space 425c flows into the atomizing housing 431 and is blown into the room from the air blowing port 29 by being attracted by the air flow blown from the air blowing port 29 as indicated by the solid line arrow. The air in the cooling space 425c flows out into the atomizing housing 431, so that the air in the housing internal space in which the water generating unit 440 is accommodated efficiently flows into the cooling space 425c from the cooling space opening 425d. . The airflow in the internal space of the housing is heated by the heat radiating plate 338 and the heat radiating fins 338a for a short time. Since this heated air flows into the cooling space 425c, even when the indoor wall surface temperature and air temperature are low, such as immediately after the start of heating operation with an air conditioner in winter, the endothermic surface side of the Peltier element 441 The water condensed on the surface of the cooling plate 425 can be prevented from freezing.

図１３実施例は、ペルチェ素子４４１の大きさを越えた冷却板４２５の下部の部分に、吸水性水搬送部材４２３ａを接触させ、冷却板４２５から吸水性水搬送部材４２３ａに結露水がスムーズに流れるようにした。しかし、図１３のような構成は、結露条件の良い地域或いは環境で使用するには適しているが、冷却板４２５の結露面の一部が吸水性水搬送部材４２３ａで覆われるため、冷却板４２５の一部が有効に使われない、或いは、第一の実施例程ではないがペルチェ素子の大きさを越えた冷却板４２５の下部で結露に寄与しない放熱があるので、消費電力の抑制の点では図１１，図１２に示す実施例と較べると不充分である。   In the embodiment of FIG. 13, the water-absorbing water transport member 423a is brought into contact with the lower part of the cooling plate 425 that exceeds the size of the Peltier element 441, and the condensed water smoothly flows from the cooling plate 425 to the water-absorbing water transport member 423a. I made it flow. However, the configuration as shown in FIG. 13 is suitable for use in an area or environment where the dew condensation condition is good. However, since a part of the dew condensation surface of the cooling plate 425 is covered with the water-absorbing water transport member 423a, the cooling plate Part of 425 is not used effectively, or although not as in the first embodiment, there is heat radiation that does not contribute to condensation at the lower part of the cooling plate 425 exceeding the size of the Peltier element. In this respect, it is insufficient as compared with the embodiment shown in FIGS.

以上のことから、結露条件の悪い地域で使用する構成は、図１１，図１２に示す実施例のように、冷却板４２５の結露に寄与しない部分を小さくし、また、図１３で検討した吸水性水搬送部材４２３ａが接触する部分を冷却板４２５から除去して、吸水性水搬送部材４２３ａを冷却板４２５の下部と離して配置する構成が適している。図１１，図１２の構成は、冷却板４２５の全面を結露に有効に使用できると共に、結露に寄与しない放熱を抑制できる。   From the above, the configuration used in an area where the dew condensation condition is bad is to reduce the portion of the cooling plate 425 that does not contribute to dew condensation as in the embodiment shown in FIGS. 11 and 12, and the water absorption studied in FIG. A configuration in which the portion where the hydrophilic water conveyance member 423a contacts is removed from the cooling plate 425 and the water-absorbing water conveyance member 423a is arranged apart from the lower portion of the cooling plate 425 is suitable. 11 and 12 can effectively use the entire surface of the cooling plate 425 for dew condensation, and can suppress heat dissipation that does not contribute to dew condensation.

図１１，図１２のように、上記冷却板４２５の下方に間隔を空けて設けられた吸水性水搬送部材４２３ａは、冷却板４２５の表面に結露して、滴下又は流下してくる水を受ける。この吸水性水搬送部材４２３ａ，４２３は、導水経路の一部を構成するものであり、結露した水が毛細管現象で移動するように多孔質や繊維質の素材で構成されている。吸水性水搬送部材４２３には、適所に穴を設け、この穴に前記の霧化電極４２２の一端の導水部４２２ｂを挿入する。これにより、吸水性水搬送部材４２３の毛細管現象により導びかれた水が、導水部４２２ｂを通して霧化部４２２ａに供給される。   As shown in FIGS. 11 and 12, the water-absorbing water transport member 423 a provided below the cooling plate 425 with a gap receives water that is condensed on the surface of the cooling plate 425 and drops or flows down. . These water-absorbing water transport members 423a and 423 constitute part of the water guide path and are made of a porous or fibrous material so that the condensed water moves by capillary action. The water-absorbing water transport member 423 is provided with a hole at an appropriate position, and the water guiding portion 422b at one end of the atomizing electrode 422 is inserted into the hole. Thereby, the water guided by the capillary phenomenon of the water-absorbing water transport member 423 is supplied to the atomizing unit 422a through the water guiding unit 422b.

以上説明したように、空気調和用の送風ファンを運転し、ペルチェ素子に通電することにより、冷却空間と冷却空間外の空気を流動させるので、水生成部のための専用のファンが不要となり、資源の節約および軽量化が図れる。また、水生成部専用のファンを運転するためのエネルギーも不要となる。 As described above, driving a blower fan for air-conditioning, by energizing the Peltier element, since flowing the cooling space the cooling space out of the air, a dedicated fan for water generating unit is not required , Resource saving and weight reduction can be achieved. Moreover, the energy for operating the fan only for a water production | generation part is also unnecessary.

このため、静電霧化装置を搭載して、室内環境を快適にしつつ、省資源，軽量，省エネに適する空気調和機を提供することができる。   For this reason, it is possible to provide an air conditioner that is equipped with an electrostatic atomizer and is suitable for resource saving, light weight, and energy saving while making the indoor environment comfortable.

また、冷却空間を形成し、該冷却空間に面して前記冷却板の面を鉛直方向に平行に設け、この冷却板の下方に間隔を空けて上記導水経路の一部を構成する吸水性水搬送部材を配置し、前記冷却板に結露した結露水を前記吸水性水搬送部材に滴下又は流下させる構成としている。これにより、冷却板の結露に寄与しない部分を小さくし、冷却板の全面を結露に有効に使用できると共に、結露に寄与しない放熱を抑制できる。 Further, to form a cold却空, facing the cooling space disposed parallel to the plane of the cooling plate in a vertical direction, water absorption which constitutes a part of the water guide paths spaced below the cooling plate A water conveyance member is disposed, and the condensed water condensed on the cooling plate is dropped or allowed to flow down on the water-absorbing water conveyance member. Thereby, the part which does not contribute to dew condensation of a cooling plate can be made small, the whole surface of a cooling plate can be used effectively for dew condensation, and the heat radiation which does not contribute to dew condensation can be suppressed.

また、送風ファン若しくはペルチェ素子の吸放熱用の送風機に通電せず、前記ペルチェ素子に通電することにより、主気流とは別の、前記複数の開口を流入口，流出口とする流路に副気流を生ぜしめ、該副気流の流路中に前記ペルチェ素子の高温部に取付けられた放熱板を位置させると共に、該副気流に臨んで上下に長い冷却空間開口を有する冷却空間を形成し、該冷却空間に面して前記冷却板の面を鉛直方向に平行に設けている。 Also, feeding does not energize the wind fan or blower for absorbing the heat of the Peltier element, by energizing the Peltier element, separate from the main stream inlet and said plurality of openings, the flow path and the outlet A sub-air flow is generated, and a heat sink attached to the high temperature part of the Peltier element is positioned in the flow path of the sub-air flow, and a cooling space having a long cooling space opening is formed facing the sub-air flow. The surface of the cooling plate is provided parallel to the vertical direction so as to face the cooling space.

これにより、冷却空間と冷却空間外の空気を流動させるので、水生成部のための専用のファンが不要となり、資源を節約し、軽量化が図れる。また、水生成部ファンを運転するためのエネルギーも不要となる。   Thereby, since the air outside the cooling space and the cooling space is caused to flow, a dedicated fan for the water generating unit is not necessary, and resources can be saved and the weight can be reduced. In addition, energy for operating the water generator fan is not required.

また、水生成部のためのファンが無いので、空気調和機が冷房，暖房，除湿，送風等の運転をしていないときでも静電霧化装置だけの運転ができ、低騒音で室内を脱臭して質の高い環境に維持することができる。   In addition, since there is no fan for the water generation unit, only the electrostatic atomizer can be operated even when the air conditioner is not operating for cooling, heating, dehumidification, ventilation, etc., and the room is deodorized with low noise. And maintain a high quality environment.

このため、静電霧化装置を搭載して、低騒音で室内環境を快適にしつつ、省資源，軽量，省エネに適する空気調和機を得ることができる。   For this reason, an air conditioner suitable for resource saving, light weight, and energy saving can be obtained while mounting the electrostatic atomizer and making the indoor environment comfortable with low noise.

また、前記筐体に設けた開口の一つが背面下部に開口している。 Also, one of the opening provided in front Kikatami body is open at the bottom rear.

これにより、使用者の目に付かない背面に開口することで、外観を損なうこと無く、副気流の入口を設けることでき、ペルチェ素子の放熱による上昇気流が円滑に形成され、水生成部が十分冷却されて、結露が順調に進む。   As a result, it is possible to provide an auxiliary airflow inlet without damaging the external appearance by opening the back surface invisible to the user's eyes. Cooling and condensation progresses smoothly.

このため、外観を損なうこと無く、霧化用水の供給が確実に行われる空気調和機を得ることができる。   For this reason, the air conditioner by which the supply of the water for atomization is performed reliably can be obtained, without impairing an external appearance.

また、前記風路壁に形成された開口がフィルターと熱交換器の間の風路に開口している。 Further, an opening formed in the front Kifuro wall is open to the wind passage between the filter and the heat exchanger.

これにより、使用者の目に付かない内部に開口することで、外観を損なうこと無く、副気流の出口を設けることでき、上述と同様に、外観を損なうこと無く、霧化用水の供給が確実に行われる空気調和機を得ることができる。   As a result, it is possible to provide an outlet for the secondary airflow without damaging the appearance by opening the inside which is not visible to the user, and as with the above, the supply of atomizing water is ensured without damaging the appearance. Can be obtained.

また、前記開口の一つが筐体上面に開口している。 Also, one of the pre-Symbol opening is open to the housing top surface.

これにより、使用者の目に付かない上面に開口することで、上述と同様の空気調和機を得ることができる。   Thereby, the air conditioner similar to the above can be obtained by opening on the upper surface which is not visible to the user.

また、前記放熱板に放熱フィンを備え、放熱フィンの長寸方向を鉛直方向に略平行（鉛直）にする。 Also it includes a radiation fin before Symbol radiating plate is substantially parallel (vertical) the elongate direction of the heat radiating fins in the vertical direction.

これにより、副気流の生成が熱交換器に室内空気を送風する送風ファンの運転に伴う誘引力や、前記放熱板からの放熱に伴う気流の熱膨張による上昇力によって生ずる副気流が放熱フィンに沿ってスムーズに上方に流れ、放熱が円滑に行われる。   As a result, the secondary airflow generated by the attraction force accompanying the operation of the blower fan that blows the room air to the heat exchanger or the rising force due to the thermal expansion of the airflow accompanying the heat dissipation from the heat sink is generated in the heat dissipation fin. The air flows smoothly upward along the surface, so that heat dissipation is performed smoothly.

このため、放熱板の冷却が効率良く行われ、水生成部が十分冷却されて、結露が順調に進み、霧化用水の供給が確実に行われる空気調和機を得ることができる。   For this reason, cooling of a heat sink is efficiently performed, a water production | generation part is fully cooled, dew condensation progresses smoothly, and the air conditioner by which the supply of the water for atomization can be performed reliably can be obtained.

また、前記水生成部の上方に、庇状の開口制限部材を設ける。 Further, above the front Symbol water producing section, provided eaves-shaped aperture restriction member.

これにより、冷却板を流れる気流と副気流との混合による温湿度の交換が適正な範囲になるように、開口制限部材の大きさを変えて実験し、効果を確かめながら、開口制限部材の大きさを決定することができる。   As a result, the size of the aperture limiting member was tested while changing the size of the aperture limiting member so that the exchange of temperature and humidity by mixing the airflow flowing through the cooling plate and the auxiliary airflow would be in an appropriate range, and confirming the effect. Can be determined.

このため、水生成部で霧化用水を確実に生成できる空気調和機を得ることができる。   For this reason, the air conditioner which can produce | generate the water for atomization reliably in a water production | generation part can be obtained.

冷却板が配置された冷却空間と霧化部の配置された空気吹出し口とを連通する通路を形成し、冷却空間内の空気が空気吹出し口から室内に送風される構成とした。これにより、放熱板，放熱フィンにより加熱された筐体内部空間の空気が冷却空間内に効率的に流入するので、室内の壁面温度及び空気温度が低い場合でも冷却板表面に結露した水分が凍結するのを抑制できる。 And arranged air outlet of the cooling space and the atomization unit to cold却板are arranged to form a passage communicating with the air in the cooling space is configured to be blown from the air outlet into the room. As a result, the air inside the housing heated by the heat radiating plate and the heat radiating fins efficiently flows into the cooling space, so that moisture condensed on the surface of the cooling plate is frozen even when the indoor wall surface temperature and air temperature are low. Can be suppressed.
