It is formed so as to supply air obliquely downward.
[0052] 前記ケーシング(11)の内部には、前記吸込口(12)から前記吹出口(13)までの間 に被処理空気の流れる空気流路(15)が形成されている。この空気流路(15)には、空 気の流れの上流側から下流側に向力つて順に、イオン化ユニット (25)、室内熱交換 器 (20)、及びファン(14)が配置されて 、る。 [0052] In the casing (11), an air flow path (15) through which air to be treated flows is formed between the suction port (12) and the blowout port (13). In this air flow path (15), an ionization unit (25), an indoor heat exchanger (20), and a fan (14) are arranged in order from the upstream side to the downstream side of the air flow. The
[0053] 前記イオンィ匕ユニット(25)は、吸込口(12)から取り込まれた空気中の塵埃を放電 により帯電させるものであり、帯電された塵埃が室内熱交 (20)の表面に付着す る。 [0053] The ionizer unit (25) charges the dust in the air taken in from the suction port (12) by discharging, and the charged dust adheres to the surface of the indoor heat exchanger (20). The
[0054] 具体的には、図 2に示すように、イオンィ匕ユニット (25)は、放電の基端となる放電 極 (31)と、放電極 (31)に対向する対向極 (32)とで構成される。  Specifically, as shown in FIG. 2, the ionizer unit (25) includes a discharge electrode (31) serving as a base end of discharge and a counter electrode (32) facing the discharge electrode (31). Consists of.
[0055] 前記放電極 (31)は、線状又は棒状に形成され、空気流れ方向と直交する左右方 向に延びている。この放電極(31)は、その線径が約 0. 2mmのタングステン線で構 成されている。前記対向極 (32)は、板状又は面状に形成され、放電極 (31)と略平行 に配置されている。このように、放電極 (31)と対向極 (32)とが上下方向に交互に複 数配設されている。  [0055] The discharge electrode (31) is formed in a linear shape or a rod shape, and extends in the left-right direction perpendicular to the air flow direction. The discharge electrode (31) is composed of a tungsten wire having a wire diameter of about 0.2 mm. The counter electrode (32) is formed in a plate shape or a planar shape, and is disposed substantially parallel to the discharge electrode (31).

The description of the arrangement of the ionizer unit (25) with respect to the air flowing in from the side is omitted, but the configuration is the same.

The first heat exchanger (21) is arranged near the front surface of the air flow path (15) with its upper end inclined to the rear surface side. The second heat exchanger (22) is disposed near the rear surface of the air flow path (15) with its upper end inclined to the front side and in contact with the upper end of the first heat exchanger (21). Yes.
[0061] 前記第 1及び第 2熱交換器 (21, 22)のそれぞれの下方には、第 1及び第 2熱交換 器 (21, 22)で発生した凝縮水を受けるドレンパン (23)が設けられている。このドレン パン (23)には、回収した凝縮水を室外に排水する排水管 (24)が接続されて!、る。  [0061] A drain pan (23) for receiving condensed water generated in the first and second heat exchangers (21, 22) is provided below each of the first and second heat exchangers (21, 22). It has been. The drain pan (23) is connected with a drain pipe (24) for draining the collected condensed water to the outside!
[0062] 前記ファン(14)は、回転動作により室内空気を吸込口(12)力 ケーシング(11)内 に取り込み、室内熱交換器 (20)で処理した空気を吹出口(13)から室内空間へ供給 するためのものである。  [0062] The fan (14) takes in indoor air into the casing (11) through the suction port (12) force casing by rotation, and the air treated by the indoor heat exchanger (20) from the outlet (13) to the indoor space. It is for supplying to
[0063] 前記空気調和装置 (100)の室外機 (50)は、室外熱交換器 (51)と室外機ファン (5 2)とを備えている。  [0063] The outdoor unit (50) of the air conditioner (100) includes an outdoor heat exchanger (51) and an outdoor unit fan (52).
[0064] 前記室外熱交換器 (51)の下方には、室外熱交換器 (51)で発生した凝縮水を受 けるドレンパン(53)が設けられている。このドレンパン(53)には、室内熱交^^ (20) に洗浄水を供給する水供給ユニット (60)が接続されて!ヽる。  [0064] Below the outdoor heat exchanger (51), a drain pan (53) for receiving condensed water generated in the outdoor heat exchanger (51) is provided. The drain pan (53) is connected with a water supply unit (60) for supplying cleaning water to the indoor heat exchanger (^).
[0065] 前記水供給ユニット (60)は、洗浄水の流路をなす水搬送配管 (61)と、室外熱交 換器 (51)で発生した凝縮水を、水搬送配管 (61)を通して室内熱交換器 (20)に洗浄 水として供給する水搬送ポンプ (62)とを備えて!/ヽる。 [0065] The water supply unit (60) is configured to pass the condensed water generated in the water transfer pipe (61) and the outdoor heat exchanger (51), which form a flow path of the washing water, through the water transfer pipe (61).

With such a configuration, the cleaning water from the nozzle cover can be sprayed like a shower, and the cleaning water can be supplied to the entire surface of the indoor heat exchanger (20). Furthermore, since the supply direction of the wash water can be changed, it is advantageous to supply the wash water to the entire surface of the indoor heat exchanger (20) by various movements such as swinging the nozzle.
[0067] なお、図 3に示すように、前記水供給ユニット (60)は、凝縮水を一時保管するため の保管タンク(63)を備えた構成にしても構わない。この場合には、一定量の凝縮水 がたまった後に、水搬送ポンプ (62)により保管タンク (63)から取り出された凝縮水が 洗浄水として室内熱交 (20)に供給される。  [0067] As shown in FIG. 3, the water supply unit (60) may include a storage tank (63) for temporarily storing condensed water.

[0068] 運転動作  [0068] Driving action
次に、本実施形態の空気調和装置(100)の運転動作について説明する。まず、 空気調和装置(100)の冷房運転動作につ!、て説明する。  Next, the operation of the air conditioner (100) of the present embodiment will be described. First, the cooling operation of the air conditioner (100) will be described.
[0069] 図 1に示すように、空気調和装置(100)の運転時には、ファン(14)が運転状態とな る。また、直流電源力もイオンィ匕ユニット (25)に直流電圧が印加され、イオン化ュ-ッ ト(25)で放電が行われる。さらに、室内熱交 (20)の内部には低圧の液冷媒が流 通し、この室内熱交 (20)が蒸発器として機能する。  As shown in FIG. 1, when the air conditioner (100) is in operation, the fan (14) is in an operating state. In addition, a DC voltage is applied to the ionization unit (25), and a discharge is performed in the ionization unit (25). Furthermore, low-pressure liquid refrigerant flows inside the indoor heat exchanger (20), and this indoor heat exchanger (20) functions as an evaporator.
[0070] 室内空気が吸込口(12)力 ケーシング(11)内に導入されると、この空気中の塵 埃はイオンィ匕ユニット (25)により帯電する。帯電した塵埃は、室内熱交翻 (20)に付 着する。  [0070] When indoor air is introduced into the inlet (12) force casing (11), the dust in the air is charged by the ionic unit (25). Charged dust adheres to indoor heat exchange (20).
[0071] ここで、冷房運転中の室内熱交 (20)には凝縮水が発生するため、この凝縮 水により、室内熱交換器 (20)の表面に付着した塵埃が洗い流され、室内熱交換器 (2 0)の下方に設けられたドレンパン (23)で回収される。回収された凝縮水は、排水管( 24)を通って室外に排水される。  [0071] Here, since condensed water is generated in the indoor heat exchanger (20) during the cooling operation, the dust adhering to the surface of the indoor heat exchanger (20) is washed away by the condensed water, and the indoor heat exchange is performed. It is collected by a drain pan (23) provided below the vessel (20). The collected condensed water is drained outside through the drain pipe (24).
[0072] イオンィ匕ユニット(25)を経て清浄ィ匕された空気は、室内熱交 (20)を流通する 。室内熱交換器 (20)では、空気から冷媒の蒸発熱が奪われ、被処理空気の冷却が 行われる。以上のようにして清浄ィ匕及び温調された空気は、吹出口(13)から室内空 間へ供給される。 [0072] The air purified through the ionizer unit (25) circulates in the indoor heat exchanger (20). In the indoor heat exchanger (20), the heat of evaporation of the refrigerant is taken from the air, and the air to be treated is cooled. The air that has been cleaned and temperature-controlled as described above is discharged from the air outlet (13) into the room air. Supplied between.
[0073] 次に、暖房運転動作について、冷房運転動作と異なる動作のみを説明する。空 気調和装置(100)の運転時には、室外熱交換器 (51)の内部には低圧の液冷媒が流 通し、この室外熱交翻 (51)が蒸発器として機能する。  [0073] Next, regarding the heating operation, only the operation different from the cooling operation will be described. During operation of the air conditioner (100), low-pressure liquid refrigerant flows inside the outdoor heat exchanger (51), and this outdoor heat exchange (51) functions as an evaporator.
[0074] 室外熱交換器 (51)では凝縮水が発生し、この凝縮水は室外熱交換器 (51)の下 方に設けられたドレンパン (53)で回収される。回収された凝縮水は、水搬送ポンプ (6 2)により水搬送配管 (61)を通して室内熱交 (20)に洗浄水として供給される。こ れにより、暖房運転動作時においても、水供給ユニット(60)によって室内熱交換器 (2 0)に付着した塵埃を除去することができる。  [0074] Condensed water is generated in the outdoor heat exchanger (51), and this condensed water is recovered by a drain pan (53) provided below the outdoor heat exchanger (51). The collected condensed water is supplied as washing water to the indoor heat exchanger (20) through the water transfer pipe (61) by the water transfer pump (62). Thereby, even during the heating operation, dust attached to the indoor heat exchanger (20) can be removed by the water supply unit (60).
[0075] 以上のように、本実施形態 1に係る空気調和装置(100)によれば、イオン化ュニッ ト (25)により流入空気中の塵埃を帯電させると、帯電した塵埃が室内熱交換器 (20) に電気的に付着し、水供給ユニット (60)で供給される洗浄水により除去される。この ため、室内熱交換器 (20)で凝縮水が発生しない暖房運転時においても、室内熱交 換器 (20)に付着した塵埃が除去され、空調性能を確保する上で有利となる。  [0075] As described above, according to the air conditioner (100) of the first embodiment, when the dust in the inflowing air is charged by the ionization unit (25), the charged dust is transferred to the indoor heat exchanger ( 20) and is removed by the washing water supplied by the water supply unit (60). For this reason, even during heating operation in which condensed water is not generated in the indoor heat exchanger (20), dust adhering to the indoor heat exchanger (20) is removed, which is advantageous in ensuring air conditioning performance.

[0084] 以上のように、本実施形態 2に係る空気調和装置(150)によれば、凝縮水生成ュ ニット (70)により室外空気中の水分を凝縮させて生成した凝縮水を洗浄水として室 内熱交翻 (20)に供給するようにしたから、冷暖房運転中にかかわらず凝縮水を安 定的に得ることができる。  [0084] As described above, according to the air conditioner (150) according to the second embodiment, the condensed water generated by condensing the moisture in the outdoor air by the condensed water generation unit (70) is used as washing water. Since it is supplied to the indoor heat exchanger (20), the condensed water can be stably obtained regardless of the air conditioning operation.
[0085] <実施形態 3 >  [0085] <Embodiment 3>
図 6は本発明の実施形態 3に係る空気調和装置の構成を示す概略図である。前 記実施形態 2との違いは、室内熱交換器 (20)よりも上流側にストリーマ放電を行う放 電ユニット (30)を設けた点であるため、以下、実施形態 2と同じ部分については同じ 符号を付し、相違点についてのみ説明する。  FIG. 6 is a schematic diagram showing the configuration of the air-conditioning apparatus according to Embodiment 3 of the present invention. The difference from the second embodiment is that a discharge unit (30) that performs streamer discharge is provided upstream of the indoor heat exchanger (20). Only the differences will be described with the same reference numerals.
[0086] 図 6に示すように、空気調和装置 (200)の室内機(10)の空気流路(15)中には、室 内熱交換器 (20)よりも空気流れ方向の上流側に放電ユニット(30)が設けられている 。この放電ユニット(30)は、室内空気中の被処理成分を分解するためにストリーマ放 電を行うものである。ストリーマ放電により空気の絶縁破壊が生じると、空気中で活性 種 (ラジカル、高速電子、励起分子等)が発生し、他の放電と比較して高活性の活性 種を多量に生成することができる。 [0086] As shown in FIG. 6, in the air flow path (15) of the indoor unit (10) of the air conditioner (200), the air flow direction is more upstream than the indoor heat exchanger (20). Discharge unit (30) is provided . This discharge unit (30) performs streamer discharge in order to decompose a component to be treated in room air. When air breakdown occurs due to streamer discharge, active species (radicals, fast electrons, excited molecules, etc.) are generated in the air, and a large amount of highly active active species can be generated compared to other discharges. .
[0087] このように、空気調和装置 (200)の空気流路(15)にストリーマ放電を行う放電ュニ ット(30)を配置すれば、例えばグロ一放電やコロナ放電と比較して活性種を多量に 生成することができ、この空気調和装置(200)における単位設置スペースあたりの被 処理成分の分解性能を向上させて安定した空気浄ィ匕効率を得ることができる。  [0087] In this way, if the discharge unit (30) for performing the streamer discharge is arranged in the air flow path (15) of the air conditioner (200), it is more active than, for example, glow discharge or corona discharge. A large amount of seeds can be generated, and the decomposition performance of the component to be treated per unit installation space in the air conditioner (200) can be improved to obtain stable air purification efficiency.
[0088] また、水供給ユニット (60)は、凝縮水生成ユニット(70)で生成した凝縮水とともに 室外熱交換器 (51)で発生した凝縮水を、洗浄水として室内熱交換器 (20)に供給す るように構成されている。  [0088] Further, the water supply unit (60) uses the condensed water generated in the outdoor heat exchanger (51) together with the condensed water generated in the condensed water generating unit (70) as washing water, to the indoor heat exchanger (20). It is configured to supply to
[0089] 以上のように、本実施形態 3に係る空気調和装置 (200)によれば、放電ユニット (3 0)のストリーマ放電により空気の絶縁破壊が生じると、空気中で活性種 (ラジカル、高 速電子、励起分子等)が発生し、他の放電と比較して高活性の活性種を多量に生成 することができる。これにより、室内熱交 (20)の除菌が行われるから、室内熱交 (20)でカビゃ細菌が繁殖することを抑制する上で有利となる。  As described above, according to the air conditioner (200) according to the third embodiment, when the dielectric breakdown of air occurs due to the streamer discharge of the discharge unit (30), the active species (radicals, High-speed electrons, excited molecules, etc.) are generated, and high-activity active species can be produced in a large amount compared to other discharges. As a result, sterilization of the indoor heat exchange (20) is performed, which is advantageous in suppressing the growth of bacteria in the indoor heat exchange (20).
[0090] <実施形態 4>  <Embodiment 4>
図 7は本発明の実施形態 4に係る空気調和装置の構成を示す概略図である。前 記実施形態 3との違いは、室内熱交翻 (20)で発生した凝縮水を保管タンク (63)に 保管して洗浄水として再利用する点であるため、以下、実施形態 3と同じ部分につい ては同じ符号を付し、相違点についてのみ説明する。  FIG. 7 is a schematic diagram showing the configuration of the air-conditioning apparatus according to Embodiment 4 of the present invention. The difference from the third embodiment is that the condensed water generated in the indoor heat exchange (20) is stored in the storage tank (63) and reused as cleaning water. Parts are denoted by the same reference numerals, and only the differences will be described.
[0091] 図 7に示すように、空気調和装置 (250)の室外機 (50)には、室内熱交換器 (20)に 供給する洗浄水を保管する保管タンク (63)が設けられて 、る。この保管タンク (63)に は、室外熱交換器 (51)で発生した凝縮水や凝縮水生成ユニット (70)で生成した凝 縮水の他に、室内熱交換器 (20)で発生した凝縮水が保管されるようになって!/、る。  As shown in FIG. 7, the outdoor unit (50) of the air conditioner (250) is provided with a storage tank (63) for storing cleaning water supplied to the indoor heat exchanger (20). The In addition to the condensed water generated in the outdoor heat exchanger (51) and condensed water generated in the condensed water generation unit (70), the storage tank (63) contains condensed water generated in the indoor heat exchanger (20). Is now stored! /
[0092] ここで、室外熱交 (51)及び凝縮水生成ユニット (70)の凝縮水は保管タンク (6 3)内にそのまま保管されるのに対し、室内熱交換器 (20)の凝縮水の排水経路は切り 替わるようになつている。 [0093] 以下、室内熱交換器 (20)の凝縮水の保管動作について説明する。 Here, the condensed water in the outdoor heat exchanger (51) and the condensed water generation unit (70) is stored as it is in the storage tank (63), whereas the condensed water in the indoor heat exchanger (20). The drainage route is switched. [0093] The condensate storage operation of the indoor heat exchanger (20) will be described below.
[0094] 前記室内熱交換器 (20)で発生した凝縮水はドレンパン (23)で回収され、排水管 [0094] The condensed water generated in the indoor heat exchanger (20) is recovered by a drain pan (23), and is discharged into a drain pipe.
(24)を通って室外に排水される。排水管 (24)はその管路途中で 2つに分岐しており 、保管タンク (63)内の洗浄水の水量に基づいて凝縮水の排水方向が切り替わるよう になっている。  It is drained outside through (24). The drain pipe (24) is branched into two in the middle of the pipe line, and the drain direction of the condensed water is switched based on the amount of washing water in the storage tank (63).
[0095] 具体的に、排水管 (24)の分岐点に設けられた排水切替バルブ (64)は、保管タン ク(63)内の水位を測定するフロートスィッチ (65)から出力される制御信号に基づいて 切り替わるようになつている。すなわち、保管タンク(63)内の水位が規定値よりも低い 場合には、保管タンク (63)内の水量が不足していると判断して、排水切替バルブ (64 )を切り替えて、室内熱交 (20)の凝縮水が保管タンク (63)に流入されるようにす る。これにより、室内熱交^^ (20)の凝縮水は、濾過フィルタ (66)を通過して濾過さ れた後、保管タンク (63)内に保管される。  [0095] Specifically, the drain switching valve (64) provided at the branch point of the drain pipe (24) is a control signal output from the float switch (65) for measuring the water level in the storage tank (63). It is designed to switch based on. That is, when the water level in the storage tank (63) is lower than the specified value, it is determined that the amount of water in the storage tank (63) is insufficient, and the drain switching valve (64) is switched to Allow the condensate (20) to flow into the storage tank (63). Thus, the condensed water in the indoor heat exchanger (20) is filtered through the filtration filter (66) and then stored in the storage tank (63).
[0096] 一方、保管タンク (63)内の水位が規定値よりも高 、場合には、保管タンク (63)内 に凝縮水をさらに流入させるとあふれ出すおそれがあるため、室内熱交^^ (20)の 凝縮水の保管タンク(63)内への流入を阻止すベぐ排水切替バルブ (64)を切り替え て、室内熱交換器 (20)の凝縮水がそのまま室外に排水されるようにする。  [0096] On the other hand, if the water level in the storage tank (63) is higher than the specified value, there is a risk of overflow if condensed water further flows into the storage tank (63). Switch the drainage switching valve (64) to prevent the condensate from flowing into the storage tank (63) of (20) so that the condensate in the indoor heat exchanger (20) is drained out of the room. To do.
[0097] そして、前記水搬送配管 (61)の管路途中には、清掃切替バルブ (67)が設けられ ている。この清掃切替バルブ (67)は、水搬送ポンプ (62)により保管タンク (63)から吸 V、上げた洗浄水を室内熱交換器 (20)側に供給するか、又は室内熱交換器 (20)の 凝縮水が濾過フィルタ (66)を通過する方向と逆方向であるフィルタ清掃方向から、洗 浄水を濾過フィルタ(66)に通過させるように切り替えるものである。  [0097] A cleaning switching valve (67) is provided in the middle of the water conveyance pipe (61). This cleaning switching valve (67) supplies water that has been sucked up and raised from the storage tank (63) by the water transfer pump (62) to the indoor heat exchanger (20) side, or the indoor heat exchanger (20 ) From the filter cleaning direction that is opposite to the direction in which the condensed water passes through the filtration filter (66) so as to pass the cleaning water through the filtration filter (66).
[0098] 具体的に、室内熱交 (20)力 排水される凝縮水には、室内熱交 (20)に 付着した塵埃が含まれているため、凝縮水を保管タンク (63)に保管する前に塵埃を 濾過フィルタ(66)で取り除くようにしている力 そのまま放置しておくと、濾過フィルタ( 66)が目詰まりして凝縮水が流通しなくなってしまうおそれがある。  [0098] Specifically, the condensed water discharged from the indoor heat exchanger (20) force contains dust adhering to the indoor heat exchanger (20), so the condensed water is stored in the storage tank (63). The force that removes dust with the filtration filter (66) in advance If left as it is, the filtration filter (66) may be clogged and the condensed water may not flow.
[0099] そこで、タイマーにより所定時間が経過したことを検知する力、又は濾過フィルタ( 66)の汚れ度をセンサ等により検知して、濾過フィルタ (66)の清掃が必要であると判 断された場合に、清掃切替バルブ (67)を切り替えて、水搬送ポンプ (62)により吸い 上げた洗浄水を濾過フィルタ (66)のフィルタ清掃方向側力 供給して洗浄することで[0099] Therefore, it is determined that the filtration filter (66) needs to be cleaned by detecting the force of detecting that a predetermined time has passed by the timer or the degree of contamination of the filtration filter (66) with a sensor or the like. If this happens, switch the cleaning switching valve (67) and use the water transfer pump (62) By cleaning the raised wash water by supplying side force in the filter cleaning direction of the filter (66)
、濾過フィルタ(66)に付着した塵埃を除去して清浄度を保つようにしている。 The dust adhering to the filter (66) is removed so as to maintain cleanliness.
[0100] また、前記保管タンク (63)には、保管タンク (63)内の洗浄水中の有害物を分解し て保管タンク (63)内の水質を維持すベぐ放電により活性種を発生させて洗浄水に 供給するプラズマ放電ユニット (68)が設けられて 、る。 [0100] Further, in the storage tank (63), active species are generated by a discharge that decomposes harmful substances in the wash water in the storage tank (63) to maintain the water quality in the storage tank (63). A plasma discharge unit (68) for supplying cleaning water is provided.
[0101] 以上のように、本実施形態 4に係る空気調和装置 (250)によれば、室内熱交換器 [0101] As described above, according to the air conditioner (250) of Embodiment 4, the indoor heat exchanger
(20)で発生した凝縮水が保管タンク (63)に保管され、保管タンク (63)に保管された 凝縮水が洗浄水として室内熱交 (20)に供給されるから、室内熱交 (20)で 発生した凝縮水を洗浄水として再利用することができる。  The condensed water generated in (20) is stored in the storage tank (63), and the condensed water stored in the storage tank (63) is supplied to the indoor heat exchanger (20) as washing water. ) Can be reused as washing water.
産業上の利用可能性  Industrial applicability
[0102] 以上説明したように、本発明は、室内熱交換器で凝縮水が発生しない暖房運転 時においても、室内熱交^^の洗浄を行うことができるという実用性の高い効果が得 られることから、きわめて有用で産業上の利用可能性は高い。 [0102] As described above, the present invention provides a highly practical effect that the indoor heat exchanger can be cleaned even during heating operation in which condensed water is not generated in the indoor heat exchanger. Therefore, it is extremely useful and has high industrial applicability.
