＜冷媒検知部３０の構成＞
図７は、本発明の実施の形態１に係る冷媒検知部３０における外観を示す斜視図である。図８は、本発明の実施の形態１に係る冷媒検知部３０における内部を示す斜視図である。<Structure of Refrigerant Detection Unit 30>
FIG. 7 is a perspective view showing the appearance of the refrigerant detection unit 30 according to the first embodiment of the present invention. FIG. 8 is a perspective view showing the inside of the refrigerant detection unit 30 according to the first embodiment of the present invention.

図７、図８に示すように、冷媒検知部３０は、センサ３１と、中継基板３２と、センサカバー３３と、中継基板カバー３４と、取付部材３５と、を有する。 As shown in FIGS. 7 and 8, the refrigerant detection unit 30 includes a sensor 31, a relay board 32, a sensor cover 33, a relay board cover 34, and a mounting member 35.

センサ３１は、室内に漏洩した冷媒を検知する。中継基板３２は、センサ３１の上側に隣接して配置され、センサ３１からの検知情報を室内機１０の制御装置２３に送信する。センサカバー３３は、前面および下面の表面に開口部である複数のスリット３６を有し、センサ３１を覆う。漏洩した冷媒は、複数のスリット３６を介してセンサ３１に到達する。中継基板カバー３４は、センサカバー３３の上側の隣接部にてセンサカバー３３よりも大きく構成され、表面に開口部の無い完全に密閉する状態で中継基板３２を覆う。中継基板カバー３４がセンサカバー３３よりも平面視にて大きいことにより、冷媒検知部３０に滴下する凝縮水などは、複数のスリット３６に浸入せず、中継基板カバー３４によって受け止められる。取付部材３５は、センサ３１と中継基板３２とセンサカバー３３と中継基板カバー３４とを保持する。取付部材３５は、冷媒検知部３０を筐体１１に螺子止めによって固定する状態と、冷媒検知部３０を１つの脚部１２ａに螺子止めによって固定する状態と、のいずれかの状態で固定される。 The sensor 31 detects the refrigerant leaked into the room. The relay board 32 is arranged adjacent to the upper side of the sensor 31, and transmits the detection information from the sensor 31 to the control device 23 of the indoor unit 10. The sensor cover 33 has a plurality of slits 36 having openings on the front and lower surfaces thereof, and covers the sensor 31. The leaked refrigerant reaches the sensor 31 through the plurality of slits 36. The relay board cover 34 is configured to be larger than the sensor cover 33 at an adjacent portion on the upper side of the sensor cover 33, and covers the relay board 32 in a completely sealed state without an opening on the surface. Since the relay board cover 34 is larger than the sensor cover 33 in a plan view, the condensed water or the like dripping on the refrigerant detection unit 30 does not enter the plurality of slits 36 and is received by the relay board cover 34. The mounting member 35 holds the sensor 31, the relay board 32, the sensor cover 33, and the relay board cover 34. The mounting member 35 is fixed in either a state in which the refrigerant detection unit 30 is fixed to the housing 11 by screwing, or a state in which the refrigerant detection unit 30 is fixed to one leg 12a by screwing. ..

冷媒検知部３０は、筐体１１から取り外し可能である。このため、室内機１０が壁掛け状態となる場合には、冷媒検知部３０は、１つの脚部１２ａに螺子止めされて固定され、室内機１０の筐体１１の下方かつ下方かつ外方に配置される場合がある。 The refrigerant detection unit 30 is removable from the housing 11. Therefore, when the indoor unit 10 is in a wall-mounted state, the refrigerant detection unit 30 is screwed and fixed to one leg portion 12a, and is arranged below, below, and outside the housing 11 of the indoor unit 10. May be done.

なお、冷媒検知部３０は、室内機１０とは分離して、室内の壁面に設置しても良い。冷媒検知部３０と室内機１０とは、図示しない中継配線を這いまわして接続できる距離で離間しても良い。 The refrigerant detection unit 30 may be installed on the wall surface of the room separately from the indoor unit 10. The refrigerant detection unit 30 and the indoor unit 10 may be separated from each other by a distance that can be connected by crawling a relay wiring (not shown).

また、実施の形態１では、冷媒検知部３０は、筐体１１の下部空間１５におけるシロッコファン７の隣の側壁部に固定される。しかし、冷媒検知部３０が筐体１１内で配置される箇所は、これに限られず、様々な位置で固定しても良い。 Further, in the first embodiment, the refrigerant detection unit 30 is fixed to the side wall portion next to the sirocco fan 7 in the lower space 15 of the housing 11. However, the location where the refrigerant detection unit 30 is arranged in the housing 11 is not limited to this, and may be fixed at various positions.

また、実施の形態１と異なり、冷媒検知部３０の構成は、これに限られず、様々な構成であっても良い。 Further, unlike the first embodiment, the configuration of the refrigerant detection unit 30 is not limited to this, and various configurations may be used.

また、冷媒検知部３０は、配線あるいは無線によって、室内機１０から離れた位置に配置されても良い。 Further, the refrigerant detection unit 30 may be arranged at a position away from the indoor unit 10 by wiring or wireless communication.

また、冷媒検知部３０は、１つの脚部１２ａに取り付けられる構成を採用している。しかし、これに限られず、それに類する冷媒検知部３０を固定可能な部材を用いて室内機１０の下方かつ外方に取り付けても良い。 Further, the refrigerant detection unit 30 adopts a configuration in which it is attached to one leg portion 12a. However, the present invention is not limited to this, and a similar refrigerant detection unit 30 may be attached below and outside the indoor unit 10 by using a member capable of fixing the refrigerant detection unit 30.

In the first embodiment, the air below the housing 11 in the gap formed between the floor surface and the lower surface of the housing 11 is provided on the lower surface of the housing 11 as shown by the arrow A shown in FIG. It is sucked into the lower space 15 from the suction opening 18. Then, the air sucked into the lower space 15 is pushed out to the upper space 14 by the sirocco fan 7. The air extruded into the upper space 14 passes through the indoor heat exchanger 5. The air passing through the indoor heat exchanger 5 exchanges heat with the refrigerant flowing through the indoor heat exchanger 5 to become conditioned air for cooling or heating. The conditioned air in the upper space 14 is blown into the room from the blowout opening 17 provided on the top surface of the housing 11 as shown by the arrow B shown in FIG.

＜第２形態＞
次に、第２形態について説明する。図９は、本発明の実施の形態１に係る空気調和装置１００の室内機１０における第２形態での外観を示す正面図である。<Second form>
Next, the second form will be described. FIG. 9 is a front view showing the appearance of the air conditioner 100 according to the first embodiment of the present invention in the indoor unit 10 in the second form.

図９に示す室内機１０は、第２形態である。第２形態は、室内機１０が床置き状態である１つの形態である。第２形態では、冷媒検知部３０は、筐体１１の下部空間１５内に取り付けられる。第２形態では、１対の脚部１２ａ、１２ｂは、筐体１１から取り外される。第２形態では、吸込開口部１８が床面に接地される。第２形態では、下部側壁部１３は、筐体１１から取り外される。下部側壁部１３が取り外された前面開口部２７は、筐体１１の下部側方の空気を吸い込む吸込口である。 The indoor unit 10 shown in FIG. 9 is a second form. The second form is one in which the indoor unit 10 is placed on the floor. In the second form, the refrigerant detection unit 30 is mounted in the lower space 15 of the housing 11. In the second form, the pair of legs 12a and 12b are removed from the housing 11. In the second form, the suction opening 18 is grounded to the floor surface. In the second form, the lower side wall portion 13 is removed from the housing 11. The front opening 27 from which the lower side wall portion 13 has been removed is a suction port for sucking air on the lower side of the housing 11.

なお、壁掛け金具１９は、筐体１１から取り外されても良い。 The wall-mounting metal fitting 19 may be removed from the housing 11.

＜第２形態の動作＞
第２形態では、筐体１１の前方の空気は、図９に示す図示矢印Ａのように、下部側壁部１３が取り外された前面開口部２７から下部空間１５に吸い込まれる。そして、下部空間１５に吸い込まれた空気は、シロッコファン７によって上部空間１４に押し出される。上部空間１４に押し出された空気は、室内熱交換器５を通過する。室内熱交換器５を通過する空気は、室内熱交換器５を流通する冷媒と熱交換し、冷房または暖房用の調和空気となる。上部空間１４の調和空気は、図９に示す図示矢印Ｂのように、筐体１１の天面に設けられる吹出開口部１７から室内に吹き出される。<Operation of the second form>
In the second form, the air in front of the housing 11 is sucked into the lower space 15 from the front opening 27 from which the lower side wall portion 13 has been removed, as shown by the arrow A in the drawing shown in FIG. Then, the air sucked into the lower space 15 is pushed out to the upper space 14 by the sirocco fan 7. The air extruded into the upper space 14 passes through the indoor heat exchanger 5. The air passing through the indoor heat exchanger 5 exchanges heat with the refrigerant flowing through the indoor heat exchanger 5 to become conditioned air for cooling or heating. The conditioned air in the upper space 14 is blown into the room from the blowout opening 17 provided on the top surface of the housing 11 as shown by the arrow B shown in FIG.

このように、室内機１０は、下部側壁部１３をフィルタと入れ替えることにより、下吸込みから前吸込みの形態に切り替えられる。このとき、冷媒検知部３０は、筐体１１の内部の下部空間１５、かつ、冷媒漏洩を検出しやすい床面に近い位置に設置できる。 In this way, the indoor unit 10 can be switched from the lower suction to the front suction by replacing the lower side wall portion 13 with the filter. At this time, the refrigerant detection unit 30 can be installed at a position close to the floor surface where the refrigerant leakage can be easily detected in the lower space 15 inside the housing 11.

＜第３形態＞
次に、第３形態について説明する。図１０は、本発明の実施の形態１に係る空気調和装置１００の室内機１０における第３形態での外観を示す正面図である。<Third form>
Next, the third form will be described. FIG. 10 is a front view showing the appearance of the air conditioner 100 according to the first embodiment of the present invention in the indoor unit 10 in the third form.

図１０に示す室内機１０は、第３形態である。第３形態は、室内機１０が壁掛け状態である。第３形態では、冷媒検知部３０は、１対の脚部１２ａ、１２ｂのうちの１つの脚部１２ａによって筐体１１の下方かつ外方に取り付けられる。第３形態では、吸込開口部１８から筐体１１の下方の空気が吸い込まれる。 The indoor unit 10 shown in FIG. 10 is a third form.

The wall-mounting metal fitting 19 supports the indoor unit 10 in a wall-mounted state fixed to the wall.

＜第３形態の動作＞
第３形態では、筐体１１の下方の空気は、図１０に示す図示矢印Ａのように、筐体１１の下面に設けられる吸込開口部１８から下部空間１５に吸い込まれる。そして、下部空間１５に吸い込まれた空気は、シロッコファン７によって上部空間１４に押し出される。上部空間１４に押し出された空気は、室内熱交換器５を通過する。室内熱交換器５を通過する空気は、室内熱交換器５を流通する冷媒と熱交換し、冷房または暖房用の調和空気となる。上部空間１４の調和空気は、図１０に示す図示矢印Ｂのように、筐体１１の天面に設けられる吹出開口部１７から室内に吹き出される。<Operation of the third form>
In the third mode, the air below the housing 11 is sucked into the lower space 15 from the suction opening 18 provided on the lower surface of the housing 11 as shown by the arrow A shown in FIG. Then, the air sucked into the lower space 15 is pushed out to the upper space 14 by the sirocco fan 7. The air extruded into the upper space 14 passes through the indoor heat exchanger 5. The air passing through the indoor heat exchanger 5 exchanges heat with the refrigerant flowing through the indoor heat exchanger 5 to become conditioned air for cooling or heating. The conditioned air in the upper space 14 is blown into the room from the blowout opening 17 provided on the top surface of the housing 11 as shown by the arrow B shown in FIG.

以上のように、空気調和装置１００の室内機１０は、室内機１０が第１形態と第２形態と第３形態とを選択自在に配置される。そして、室内機１０がこれらの形態に変更されても、冷媒検知部３０が取り外し可能であるので、冷媒検知部３０が筐体１１の下方かつ外方に取り付けられる場合がある。したがって、冷媒検知部３０が床面に近い位置に設置でき、漏洩した冷媒を検知する検知性能が向上できる。 As described above, in the indoor unit 10 of the air conditioner 100, the indoor unit 10 is arranged so that the first form, the second form, and the third form can be freely selected. Even if the indoor unit 10 is changed to these forms, the refrigerant detection unit 30 is removable, so that the refrigerant detection unit 30 may be attached below and outside the housing 11. Therefore, the refrigerant detection unit 30 can be installed at a position close to the floor surface, and the detection performance for detecting the leaked refrigerant can be improved.

＜実施の形態１の効果＞
実施の形態１によれば、空気調和装置１００の室内機１０は、室内熱交換器５と送風機としてのシロッコファン７とを筐体１１の内部に備える。空気調和装置１００の室内機１０は、取り外し可能な冷媒検知部３０を備える。冷媒検知部３０は、筐体１１の内部に取り付けられる状態と、筐体１１の下方かつ外方に取り付けられる状態と、を選択自在に配置される。<Effect of Embodiment 1>
According to the first embodiment, the indoor unit 10 of the air conditioner 100 includes an indoor heat exchanger 5 and a sirocco fan 7 as a blower inside the housing 11. The indoor unit 10 of the air conditioner 100 includes a removable refrigerant detection unit 30. The refrigerant detection unit 30 can be freely arranged between a state in which it is mounted inside the housing 11 and a state in which it is mounted below and outside the housing 11.

この構成によれば、空気調和装置１００の室内機１０が床面から離れた高い位置に設置されても、冷媒検知部３０は、筐体１１の下方かつ外方に取り付けられる状態に変更され、冷媒濃度が高くなる床面付近に近づけて配置できる。したがって、空気調和装置１００の室内機１０が床面から離れた高い位置に設置されても、冷媒検知部３０が漏洩した冷媒を検知できる。 According to this configuration, even if the indoor unit 10 of the air conditioner 100 is installed at a high position away from the floor surface, the refrigerant detection unit 30 is changed to be attached to the lower side and the outer side of the housing 11. It can be placed close to the floor where the refrigerant concentration is high. Therefore, even if the indoor unit 10 of the air conditioner 100 is installed at a high position away from the floor surface, the refrigerant detection unit 30 can detect the leaked refrigerant.

実施の形態１によれば、室内機１０は、筐体１１の内部にて室内熱交換器５を配置する上部空間１４と、筐体１１の内部にて送風機としてのシロッコファン７を配置する下部空間１５と、を有する。室内機１０は、床置き状態と、壁掛け状態と、を選択自在に配置される。冷媒検知部３０は、室内機１０が床置き状態のときに、筐体１１の下部空間１５に取り付けられる状態と、室内機１０が壁掛け状態のときに、筐体１１の下方かつ外方に取り付けられる状態と、を選択自在に配置される。 According to the first embodiment, the indoor unit 10 has an upper space 14 in which the indoor heat exchanger 5 is arranged inside the housing 11 and a lower portion in which the sirocco fan 7 as a blower is arranged inside the housing 11. It has a space 15. The indoor unit 10 is arranged so that it can be placed on the floor or hung on the wall. The refrigerant detection unit 30 is attached to the lower space 15 of the housing 11 when the indoor unit 10 is placed on the floor, and is attached to the lower and outer sides of the housing 11 when the indoor unit 10 is wall-mounted. It is arranged so that it can be selected.

この構成によれば、空気調和装置１００の室内機１０が床面から離れた高い位置に設置される壁掛け状態で配置されても、冷媒検知部３０は、筐体１１の下方かつ外方に取り付けられる状態に変更され、冷媒濃度が高くなる床面付近に近づけて配置できる。したがって、空気調和装置１００の室内機１０が壁掛け状態となって床面から離れた高い位置に設置されても、冷媒検知部３０が漏洩した冷媒を検知できる。 According to this configuration, even if the indoor unit 10 of the air conditioner 100 is arranged in a wall-mounted state where it is installed at a high position away from the floor surface, the refrigerant detection unit 30 is attached below and outside the housing 11. It can be placed close to the floor surface where the refrigerant concentration is high. Therefore, even if the indoor unit 10 of the air conditioner 100 is hung on the wall and installed at a high position away from the floor surface, the refrigerant detecting unit 30 can detect the leaked refrigerant.

実施の形態１によれば、室内機１０は、壁掛け状態に支持する壁掛け金具１９を備える。 According to the first embodiment, the indoor unit 10 includes a wall-mounting metal fitting 19 that supports the wall-mounted state.

この構成によれば、空気調和装置１００の室内機１０は、床置き型であっても、壁掛け金具１９によって壁掛け状態で設置できる。 According to this configuration, the indoor unit 10 of the air conditioner 100 can be installed in a wall-mounted state by the wall-mounting metal fitting 19, even if it is a floor-standing type.

実施の形態１によれば、筐体１１に取り外し可能な１対の脚部１２ａ、１２ｂを備える。１対の脚部１２ａ、１２ｂは、室内機１０が床置き状態のときに、筐体１１に取り付けられて筐体１１を下方から支持する状態と、室内機１０が壁掛け状態のときに、冷媒検知部３０を筐体１１の下方かつ外方に取り付ける状態と、を選択自在に配置される。 According to the first embodiment, the housing 11 is provided with a pair of removable legs 12a and 12b. The pair of legs 12a and 12b are the refrigerants when the indoor unit 10 is placed on the floor and is attached to the housing 11 to support the housing 11 from below, and when the indoor unit 10 is wall-mounted. A state in which the detection unit 30 is attached to the lower side and the outer side of the housing 11 can be freely arranged.

この構成によれば、空気調和装置１００の室内機１０が床面から離れた高い位置に設置される壁掛け状態で配置されても、冷媒検知部３０は、いずれかの脚部１２ａ、１２ｂによって筐体１１の下方かつ外方に取り付けられる状態に変更され、冷媒濃度が高くなる床面付近に近づけて配置できる。したがって、空気調和装置１００の室内機１０が壁掛け状態となって床面から離れた高い位置に設置されても、冷媒検知部３０が漏洩した冷媒を検知できる。 According to this configuration, even if the indoor unit 10 of the air conditioner 100 is arranged in a wall-mounted state where it is installed at a high position away from the floor surface, the refrigerant detection unit 30 is housed by any of the legs 12a and 12b. It is changed to a state where it is attached below and outside the body 11, and it can be arranged close to the floor surface where the refrigerant concentration becomes high. Therefore, even if the indoor unit 10 of the air conditioner 100 is hung on the wall and installed at a high position away from the floor surface, the refrigerant detecting unit 30 can detect the leaked refrigerant.

またこの構成によれば、空気調和装置１００の室内機１０が床置き状態で床面に設置されるときに、１対の脚部１２ａ、１２ｂによって筐体１１の下面に形成される吸込開口部１８に下方から空気を吸い込める隙間を確保できる。そして、１対の脚部１２ａ、１２ｂは、空気調和装置１００の室内機１０が壁掛け状態で配置されるときに、冷媒検知部３０がいずれかの脚部１２ａ、１２ｂに取り付けられ、冷媒検知部３０がいずれかの脚部１２ａ、１２ｂによって筐体１１の下方かつ外方に取り付けられる状態に変更される。このように、１対の脚部１２ａ、１２ｂは、空気調和装置１００の室内機１０が床置き状態のときと、壁掛け状態のときとの両方で有効利用される。 Further, according to this configuration, when the indoor unit 10 of the air conditioner 100 is installed on the floor in a floor-standing state, a suction opening formed on the lower surface of the housing 11 by the pair of legs 12a and 12b. A gap for sucking air from below can be secured in 18. Then, in the pair of legs 12a and 12b, when the indoor unit 10 of the air conditioner 100 is arranged in a wall-mounted state, the refrigerant detection unit 30 is attached to any of the legs 12a and 12b, and the refrigerant detection unit 30 is attached. The 30 is changed to be attached to the lower side and the outer side of the housing 11 by any of the legs 12a and 12b. As described above, the pair of legs 12a and 12b are effectively used both when the indoor unit 10 of the air conditioner 100 is placed on the floor and when it is hung on the wall.

実施の形態１によれば、筐体１１は、上部空間１４の上部にて開口する吹出開口部１７を有する。筐体１１は、下部空間１５の下部にて開口する吸込開口部１８を有する。筐体１１は、筐体１１の下部空間１５を覆うとともに筐体１１に取り外し可能な下部側壁部１３を有する。室内機１０は、床置き状態として、冷媒検知部３０が筐体１１の下部空間１５内に取り付けられ、１対の脚部１２ａ、１２ｂが筐体１１に取り付けられて筐体１１を下方から支持し、吸込開口部１８から筐体１１の下方の空気が吸い込まれる第１形態を有する。室内機１０は、床置き状態として、冷媒検知部３０が筐体１１の下部空間１５内に取り付けられ、１対の脚部１２ａ、１２ｂが筐体１１から取り外され、吸込開口部１８が床面に接地され、下部側壁部１３が筐体１１から取り外されて筐体１１の下部側方の空気が吸い込まれる第２形態を有する。室内機１０は、壁掛け状態として、冷媒検知部３０が１対の脚部１２ａ、１２ｂのうちの１つの脚部１２ａによって筐体１１の下方かつ外方に取り付けられ、吸込開口部１８から筐体１１の下方の空気が吸い込まれる第３形態を有する。室内機１０は、第１形態と第２形態と第３形態とを選択自在に配置される。 According to the first embodiment, the housing 11 has a blowout opening 17 that opens at the upper part of the upper space 14.
