(Collection member)
FIG. 6 is a partially enlarged perspective view showing the ultraviolet irradiation unit attached to the air conditioner. As shown in FIGS. 4 to 6, the indoor unit 20 has a collection member 24 inside the casing 21. As shown in FIG. The collecting member 24 is a member for collecting dust contained in the indoor air (return air RA). The collection member 24 includes a first filter 24a as the first collection member 24 and a second filter 24b as the second collection member 24. As shown in FIG. The second filter 24b is a filter for collecting (finer) dust that cannot be collected by the first filter 24a. ~95%). In other words, the first filter 24a is coarser than the second filter 24b. In addition, although the case where all the members which comprise the collection member 24 are filters is illustrated in this embodiment, an electric dust collector may be sufficient.
 図5に示すように、第1フィルタ24aは、空気の流れ方向において、第2フィルタ24bの上流側に配置される。以下の説明では、第1フィルタ24aの空気の流れ方向における上流側の面を下端面24cと称する。なお、本実施形態で示した捕集部材24は、第1フィルタ24a及び第2フィルタ24bを含んでいるが、本開示の室内ユニットにおける捕集部材は、第1フィルタ及び第2フィルタの何れか一方のみであってもよい。 As shown in FIG. 5, the first filter 24a is arranged upstream of the second filter 24b in the direction of air flow. In the following description, the surface of the first filter 24a on the upstream side in the air flow direction is referred to as a lower end surface 24c. Although the collection member 24 shown in the present embodiment includes the first filter 24a and the second filter 24b, the collection member in the indoor unit of the present disclosure is either the first filter or the second filter. Only one may be used.
 室内ユニット20では、吸込口25(開口部29a)からケーシング21内に吸い込まれた空気(還気RA)が捕集部材24を通過する。このとき、還気RAに含まれる塵埃が、第1フィルタ24a及び第2フィルタ24bによって捕集される。室内ユニット20では、第1フィルタ24aの下端面24cに、有害成分や臭気成分のもととなる塵埃が付着する。 In the indoor unit 20 , the air (return air RA) sucked into the casing 21 through the suction port 25 (opening 29 a ) passes through the collection member 24 . At this time, dust contained in the return air RA is collected by the first filter 24a and the second filter 24b. In the indoor unit 20, dust that causes harmful components and odor components adheres to the lower end surface 24c of the first filter 24a.
(紫外線照射ユニット)
 図6に示すように、室内ユニット20は、紫外線照射ユニット50を備えている。紫外線照射ユニット50は、第1フィルタ24aの下端面24cに紫外線UVを照射するための部位であり、光源51、光源制御部52(図2参照)、及びカバー53を備えている。光源51は、通電することによって紫外線UVを発するLED素子を備えている。光源51には図示しないレンズが装着されており、当該レンズによって、光源51で発せられた紫外線UVを下端面24cの略全面に拡散させる。なお、本実施形態で示した光源51は、ケーシング21に固定されており、下端面24cに対して定位置から紫外線UVを照射するが、光源51をケーシング21に対し変位させる変位機構をさらに備え、前記変位機構によって光源51を変位させながら下端面24cに対して紫外線UVを照射する構成としてもよい。
(Ultraviolet irradiation unit)
As shown in FIG. 6, the indoor unit 20 includes an ultraviolet irradiation unit 50. As shown in FIG. The ultraviolet irradiation unit 50 is a part for irradiating the lower end surface 24 c of the first filter 24 a with ultraviolet rays UV, and includes a light source 51 , a light source control section 52 (see FIG. 2), and a cover 53 . The light source 51 includes an LED element that emits ultraviolet UV when energized. A lens (not shown) is attached to the light source 51, and the lens diffuses the ultraviolet rays UV emitted from the light source 51 over substantially the entire bottom surface 24c. The light source 51 shown in this embodiment is fixed to the casing 21 and irradiates the lower end surface 24c with ultraviolet rays UV from a fixed position. Alternatively, the lower end surface 24c may be irradiated with ultraviolet rays UV while the light source 51 is displaced by the displacing mechanism.
 紫外線照射ユニット50は、吸込口25から捕集部材24に向けて流れる空気の流れから外れた位置に配置されている。換言すると、紫外線照射ユニット50は、底面視において、吸込口25及び捕集部材24と重ならない位置に配置されている。仮に紫外線照射ユニット50を吸込口25から捕集部材24に向けて流れる空気の流れ中に配置した場合、紫外線照射ユニット50が通風抵抗を増大させる要因となる。本開示の室内ユニット20では、紫外線照射ユニット50を吸込口25から捕集部材24に向けて流れる空気の流れから外れた位置に配置することによって、通風抵抗の増大を抑制している。 The ultraviolet irradiation unit 50 is arranged at a position away from the flow of air flowing from the suction port 25 toward the collecting member 24 . In other words, the ultraviolet irradiation unit 50 is arranged at a position that does not overlap the suction port 25 and the collecting member 24 in a bottom view. If the ultraviolet irradiation unit 50 is arranged in the flow of air flowing from the suction port 25 toward the collecting member 24, the ultraviolet irradiation unit 50 becomes a factor that increases airflow resistance. In the indoor unit 20 of the present disclosure, an increase in airflow resistance is suppressed by arranging the ultraviolet irradiation unit 50 at a position away from the flow of air flowing from the suction port 25 toward the collection member 24 .
 紫外線照射ユニット50は、カバー53を備えている。カバー53は、ケーシング21に対して光源51を支持するための部材を兼ねており、ケーシング21に対してビス止めされている。カバー53には、本体部53a及び開口部53bを備えている。光源51から発せられた紫外線UVは、開口部53bを通ってカバー53の外部の空間Aに照射される。開口部53bを通ってカバー53の外部の空間Aに照射された紫外線UVは、捕集部材24の下端面24cに照射される。 The ultraviolet irradiation unit 50 has a cover 53. The cover 53 also serves as a member for supporting the light source 51 with respect to the casing 21 and is screwed to the casing 21 . The cover 53 has a body portion 53a and an opening portion 53b. The ultraviolet rays UV emitted from the light source 51 are irradiated to the space A outside the cover 53 through the opening 53b. The ultraviolet rays UV irradiated to the space A outside the cover 53 through the opening 53b are irradiated to the lower end surface 24c of the collection member 24 .
(報知部について)
 図2に示すように、空気調和装置10は、報知部60をさらに備える。空気調和装置10では、光源制御部52が、光源51の異常を検知した場合に空調制御部15に第3信号S3を発信する。空気調和装置10では、空調制御部15が第3信号S3を受信した場合、空調制御部15が、報知部60に報知させる。このような構成の空気調和装置10では、報知部60によって、光源51に異常が生じたことをユーザに知らせることが可能となる。なお、空気調和装置10では、光源制御部52が、光源51の異常を検知した場合、例えばリモコン16の表示部17に、異常を報知するための情報を表示させても良い。

 ステップ(S202)において、光源制御部52は、光源51の電源をONとする。このとき空気調和装置10では、光源51から捕集部材24の下端面24cに向けて紫外線UVが照射される。 In step (S202), the light source control unit 52 turns on the power of the light source 51. At this time, in the air conditioner 10 , ultraviolet rays UV are emitted from the light source 51 toward the lower end surface 24 c of the collecting member 24 .
 光源制御部52は、ステップ(S202)において光源51の電源をONした後、次に、ステップ(S203)を実行する。ステップ(S203)において、光源制御部52は、第2信号S2の入力があるか否かについての判定を実行する。ステップ(S203)において、光源制御部52が、第2信号S2の入力がある(YES)と判定した場合には、次に、ステップ(S204)を実行する。一方、ステップ(S203)において、光源制御部52が、第2信号S2の入力がない(NO)と判定した場合には、第2信号S2の入力があるまで、ステップ(S203)を繰り返し実行する。 After turning on the light source 51 in step (S202), the light source control unit 52 next executes step (S203). In step (S203), the light source control unit 52 determines whether or not there is an input of the second signal S2. In step (S203), when the light source control unit 52 determines that there is an input of the second signal S2 (YES), next step (S204) is executed. On the other hand, if the light source control unit 52 determines in step (S203) that the second signal S2 is not input (NO), step (S203) is repeatedly executed until the second signal S2 is input. .
 ステップ(S204)において、光源制御部52は、光源51の電源をOFFとする。このとき空気調和装置10では、光源51から捕集部材24に向けた紫外線UVの照射が停止される。 In step (S204), the light source control unit 52 turns off the power of the light source 51. At this time, in the air conditioner 10, irradiation of the ultraviolet rays UV from the light source 51 toward the collection member 24 is stopped.
 光源制御部52は、ステップ(S204)において光源51の電源をOFFとした後、ステップ(S201)に戻って、再度ステップ(S201)以降の制御動作を実行する。 After turning off the light source 51 in step (S204), the light source control unit 52 returns to step (S201) and executes the control operations from step (S201) onwards again.
 以上説明した通り、本開示の空気調和装置10では、光源制御部52が、光源51の電源のON-OFFを制御する。 As described above, in the air conditioner 10 of the present disclosure, the light source control unit 52 controls ON/OFF of the power source of the light source 51 .
 本開示の空気調和装置10では、光源制御部52が、空調制御部15から送られる第1情報J1に基づいて、光源51の電源をON-OFFさせると好ましい。光源51は、高温の雰囲気下(例えば、40度を超える雰囲気)で使用された場合に、寿命が低下することが知られている。本開示の空気調和装置10では、光源制御部52が、第1情報J1に基づいて、光源51の電源をON-OFFさせる。具体的には、光源制御部52は、第1情報J1から光源51の周囲温度が40度を超えていることを検知した場合、光源51の電源をOFFとし、光源51の周囲温度が40度未満であることを検知した場合、光源51の電源をONとする。空気調和装置10では、このような構成により、光源51の寿命の低下を抑制することができる。さらに、このような構成の空気調和装置10では、紫外線照射ユニット50に温度センサを設ける必要がないため、紫外線照射ユニット50の構成を簡素にすることができる。なお、空気調和装置10では、第1信号S1を発信する条件に第1情報J1を組み込んで、室内温度センサ41の検出値から光源51の周囲温度が40度未満であると判断した場合に、空調制御部15が第1信号S1を発信する構成としてもよい。 In the air conditioner 10 of the present disclosure, it is preferable that the light source control unit 52 turns ON/OFF the power of the light source 51 based on the first information J1 sent from the air conditioning control unit 15 . It is known that the life of the light source 51 is shortened when used in a high temperature atmosphere (for example, an atmosphere exceeding 40 degrees). In the air conditioner 10 of the present disclosure, the light source control unit 52 turns ON/OFF the power of the light source 51 based on the first information J1. Specifically, when the light source control unit 52 detects from the first information J1 that the ambient temperature of the light source 51 exceeds 40 degrees, the power of the light source 51 is turned off, and the ambient temperature of the light source 51 reaches 40 degrees. When it is detected that the value is less than that, the light source 51 is turned on. With such a configuration, the air conditioner 10 can suppress a decrease in the life of the light source 51 . Furthermore, in the air conditioner 10 having such a configuration, the ultraviolet irradiation unit 50 does not need to be provided with a temperature sensor, so the configuration of the ultraviolet irradiation unit 50 can be simplified. In the air conditioner 10, when the first information J1 is included in the conditions for transmitting the first signal S1, and it is determined from the detection value of the room temperature sensor 41 that the ambient temperature of the light source 51 is less than 40 degrees, The air conditioning control unit 15 may be configured to transmit the first signal S1.

In step (S200), the light source control unit 52 determines whether or not the light source 51 has an abnormality. If the light source control unit 52 determines that the light source 51 is normal (YES) in step (S200), then step (S201) is executed. On the other hand, when the light source control unit 52 determines that the light source 51 has an abnormality (NO) in step (S200), next step (S205) is executed.
 ステップ(S205)において、光源制御部52は、第3信号S3を発信する。空調制御部15は、第3信号S3の入力があった場合に、報知部60により報知させる。 At step (S205), the light source control unit 52 transmits the third signal S3. The air conditioning control unit 15 causes the notification unit 60 to notify when the third signal S3 is input.

In step (S211), the light source control unit 52 determines whether or not the first signal S1 is input. If the light source controller 52 determines in step (S211) that there is an input of the first signal S1 (YES), then step (S212) is executed. On the other hand, if the light source control unit 52 determines in step (S211) that the first signal S1 is not input (NO), step (S211) is repeatedly executed until the first signal S1 is input. .
 ステップ(S212)において、光源制御部52は、光源51の電源をONとする。このとき空気調和装置10では、光源51から捕集部材24の下端面24cに向けて紫外線UVが照射される。 In step (S212), the light source control unit 52 turns on the light source 51. At this time, in the air conditioner 10 , ultraviolet rays UV are emitted from the light source 51 toward the lower end surface 24 c of the collecting member 24 .

In step (S213), the light source control unit 52 determines whether or not the first predetermined period X1 has elapsed after the power of the light source 51 was turned on. When the light source control unit 52 determines that the first predetermined period X1 has elapsed (YES) in step (S213), next step (S215) is executed. On the other hand, if the light source control unit 52 determines in step (S213) that the first predetermined period X1 has not elapsed (NO), then step (S214) is executed.
 ステップ(S214)において、光源制御部52は、第2信号S2の入力があるか否かについての判定を実行する。ステップ(S214)において、光源制御部52が、第2信号S2の入力がある(YES)と判定した場合には、次に、ステップ(S215)を実行する。一方、ステップ(S214)において、光源制御部52が、第2信号S2の入力がない(NO)と判定した場合には、第2信号S2の入力があるまで、ステップ(S213)及びステップ(S214)を繰り返し実行する。 In step (S214), the light source control unit 52 determines whether or not there is an input of the second signal S2. If the light source controller 52 determines in step (S214) that there is an input of the second signal S2 (YES), then step (S215) is executed. On the other hand, in step (S214), when the light source control unit 52 determines that there is no input of the second signal S2 (NO), step (S213) and step (S214) are performed until the second signal S2 is input. ) repeatedly.
 ステップ(S215)において、光源制御部52は、光源51の電源をOFFとする。光源制御部52は、ステップ(S215)において光源51の電源をOFFとした後、次に、ステップ(S216)を実行する。このように、空気調和装置10では、第2信号S2の入力の有無に関わらず、光源51の電源をONとした後、第1所定時間X1が経過した場合に、光源51の電源をOFFとしてもよい。 In step (S215), the light source control unit 52 turns off the power of the light source 51. After turning off the light source 51 in step (S215), the light source control unit 52 next executes step (S216). As described above, in the air conditioning apparatus 10, the power of the light source 51 is turned off when the first predetermined time X1 has elapsed after the power of the light source 51 is turned on, regardless of whether or not the second signal S2 is input. good too.
 ステップ(S216)において、光源制御部52は、光源51の電源をOFFとしてから第2所定期間X2が経過したか否かについての判定を実行する。ステップ(S216)において、光源制御部52が、第2所定期間X2が経過した(YES)と判定した場合には、ステップ(S211)に戻る。一方、ステップ(S216)において、光源制御部52が、第2所定期間X2が経過していない(NO)と判定した場合には、第2所定期間X2が経過するまで、ステップ(S216)を繰り返し実行する。 In step (S216), the light source control unit 52 determines whether or not the second predetermined period X2 has elapsed since the power of the light source 51 was turned off. In step (S216), when the light source control unit 52 determines that the second predetermined period X2 has elapsed (YES), the process returns to step (S211).

 空気調和装置10では、図10に示す制御フローを採用した場合、例えば、光源51を3時間ONとした後、3時間OFFとし、さらにその後3時間ONとして、光源51を合計6時間ONとするような制御が可能となる。これにより、光源51の1日当たりの照射時間の上限を容易に設定することが可能となる。この場合、光源制御部52が有する機能だけで光源51の電源をON-OFF制御することが可能となる。空気調和装置10では、使用時間の増加に伴う光源51の劣化を考慮して、第1所定期間X1を、使用時間の増加に応じて長くするとより好ましい。これにより、使用時間が長くなった光源51を使用した場合であっても所定の照射強度を確保することができ、除菌性能の低下を抑制することが可能となる。 In the air conditioner 10, when the control flow shown in FIG. 10 is adopted, for example, the light source 51 is turned on for 3 hours, then turned off for 3 hours, and then turned on for 3 hours, so that the light source 51 is turned on for a total of 6 hours. Such control becomes possible. This makes it possible to easily set the upper limit of the irradiation time of the light source 51 per day. In this case, the ON/OFF control of the power of the light source 51 can be performed only by the function of the light source control section 52 . In the air conditioner 10, considering the deterioration of the light source 51 as the usage time increases, it is more preferable to lengthen the first predetermined period X1 as the usage time increases. As a result, even when the light source 51 that has been used for a long time is used, a predetermined irradiation intensity can be ensured, and deterioration of the sterilization performance can be suppressed.
 以上説明した通り、本開示の空気調和装置10では、光源制御部52によって、光源51の電源を第1所定期間X1の間ONとした後、第2所定期間X2の間OFFとすることができる。 As described above, in the air conditioner 10 of the present disclosure, the light source control unit 52 can turn on the power of the light source 51 for the first predetermined period X1 and then turn it off for the second predetermined period X2. .

 ステップ(S222)において、光源制御部52が、光源51の積算照射時間Tが、所定の閾値Y未満か否かについての判定を実行する。ステップ(S222)において、光源制御部52が、光源51の積算照射時間Tが、所定の閾値Y未満である(YES)と判定した場合には、次に、ステップ(S223)を実行する。一方、ステップ(S222)において、光源制御部52が、光源51の積算照射時間Tが、所定の閾値Yを越えた(NO)と判定した場合には、次に、ステップ(S229)を実行する。 In step (S222), the light source control unit 52 determines whether or not the accumulated irradiation time T of the light source 51 is less than a predetermined threshold Y. In step (S222), when the light source control unit 52 determines that the integrated irradiation time T of the light source 51 is less than the predetermined threshold value Y (YES), next step (S223) is executed. On the other hand, if the light source control unit 52 determines in step (S222) that the accumulated irradiation time T of the light source 51 exceeds the predetermined threshold value Y (NO), then step (S229) is executed. .
 ステップ(S223)において、光源制御部52は、光源51の電源をONとする。空気調和装置10では、このとき、光源51から捕集部材24の下端面24cに向けて紫外線UVが照射される。 In step (S223), the light source control unit 52 turns on the power of the light source 51. At this time, in the air conditioner 10 , ultraviolet rays UV are emitted from the light source 51 toward the lower end surface 24 c of the collecting member 24 .
 光源制御部52は、ステップ(S223)において光源51の電源をONとした後、ステップ(S224)を実行する。ステップ(S224)において、光源制御部52は、光源51による紫外線UVの照射時間の積算を開始し、次に、ステップ(S225)を実行する。 After turning on the light source 51 in step (S223), the light source control unit 52 executes step (S224). In step (S224), the light source control unit 52 starts accumulating the irradiation time of the ultraviolet rays UV by the light source 51, and then executes step (S225).
 ステップ(S225)において、光源制御部52は、光源51の積算照射時間Tが、所定の閾値Y未満か否かについての判定を実行する。ステップ(S225)において、光源制御部52が、光源51の積算照射時間Tが、所定の閾値Y未満である(YES)と判定した場合には、次に、ステップ(S226)を実行する。一方、ステップ(S225)において、光源制御部52が、光源51の積算照射時間Tが、所定の閾値Yを越えた(NO)と判定した場合には、次に、ステップ(S227)を実行する。 In step (S225), the light source control unit 52 determines whether or not the accumulated irradiation time T of the light source 51 is less than a predetermined threshold Y. In step (S225), when the light source control unit 52 determines that the cumulative irradiation time T of the light source 51 is less than the predetermined threshold value Y (YES), next step (S226) is executed. On the other hand, if the light source control unit 52 determines in step (S225) that the accumulated irradiation time T of the light source 51 exceeds the predetermined threshold value Y (NO), then step (S227) is executed. .
 ステップ(S227)において、光源制御部52は、光源51の積算照射時間Tを「0」にリセットし、次に、ステップ(S228)を実行する。 In step (S227), the light source control unit 52 resets the accumulated irradiation time T of the light source 51 to "0", and then executes step (S228).
 ステップ(S226)において、光源制御部52は、第2信号S2の入力があるか否かについての判定を実行する。ステップ(S226)において、光源制御部52が、第2信号S2の入力がある(YES)と判定した場合には、次に、ステップ(S228)を実行する。一方、ステップ(S226)において、光源制御部52が、第2信号S2の入力がない(NO)と判定した場合には、第2信号S2の入力があるまで、ステップ(S225)~(S226)を繰り返し実行する。 At step (S226), the light source control unit 52 determines whether or not there is an input of the second signal S2. If the light source controller 52 determines in step (S226) that there is an input of the second signal S2 (YES), then step (S228) is executed. On the other hand, in step (S226), when the light source control unit 52 determines that the second signal S2 is not input (NO), steps (S225) to (S226) are performed until the second signal S2 is input. repeatedly.
 ステップ(S228)において、光源制御部52は、光源51の電源をOFFとする。光源制御部52は、ステップ(S228)において光源51をOFFさせた後、ステップ(S230)を実行する。ステップ(S222)からステップ(S229)に至った場合も同様に、光源制御部52は、光源51の積算照射時間Tを「0」にリセットし、次に、ステップ(S230)を実行する。 In step (S228), the light source control unit 52 turns off the power of the light source 51. After turning off the light source 51 in step (S228), the light source control unit 52 executes step (S230). Likewise, in the case where step (S222) is followed by step (S229), the light source control unit 52 resets the accumulated irradiation time T of the light source 51 to "0", and then executes step (S230).
 ステップ(S230)において、光源制御部52は、光源51による紫外線UVの照射が可能なタイミングであるか否かについての判定を実行する。ステップ(S230)において、光源制御部52が、光源51による紫外線UVの照射が可能なタイミングである(YES)と判定した場合には、ステップ(S221)に戻る。一方、ステップ(S230)において、光源制御部52が、光源51による紫外線UVの照射が可能なタイミングでない(NO)と判定した場合には、光源51による紫外線UVの照射が可能なタイミングになるまで、ステップ(S230)を繰り返し実行する。 In step (S230), the light source control unit 52 determines whether or not it is the timing at which the light source 51 can irradiate ultraviolet rays UV. In step (S230), when the light source control unit 52 determines that it is the timing at which the light source 51 can irradiate ultraviolet UV (YES), the process returns to step (S221). On the other hand, in step (S230), when the light source control unit 52 determines that it is not the timing at which the light source 51 can irradiate the ultraviolet ray UV (NO), the light source 51 waits until the timing at which the light source 51 can irradiate the ultraviolet ray UV. , step (S230) is repeatedly executed.
 紫外線照射ユニット50では、光源51の寿命を考慮して、1日の照射時間の上限を設定する。ある日において、光源51による紫外線UVの照射時間が上限に達していないときは、光源51による紫外線UVの照射が可能なタイミングに該当する。一方、光源51による紫外線UVの照射時間が上限に達しているときは、光源51による紫外線UVの照射が不可能なタイミングに該当する。1日の照射時間が上限の閾値Yを越えていてステップ(S227)及びステップ(S229)を経て光源OFFとなった場合、その日は光源による照射を行うことができないため、ステップ(S230)において、次の日になるまで待機する。 In the ultraviolet irradiation unit 50, the upper limit of irradiation time per day is set in consideration of the life of the light source 51. On a certain day, when the irradiation time of the ultraviolet rays UV by the light source 51 has not reached the upper limit, it corresponds to the timing when the irradiation of the ultraviolet rays UV by the light source 51 is possible. On the other hand, when the irradiation time of the ultraviolet rays UV by the light source 51 reaches the upper limit, it corresponds to the timing when the irradiation of the ultraviolet rays UV by the light source 51 is impossible. If the irradiation time per day exceeds the upper limit threshold value Y and the light source is turned off through steps (S227) and (S229), irradiation by the light source cannot be performed on that day, so in step (S230), wait until the next day.
