In the duct holding member according to another aspect of the embodiment, an airtight body disposed in at least one of the space between the first member and the window and the space between the second member and the window is provided. Thereby, the airtightness with the opening of the window can be enhanced.

[0010] <First Embodiment> 1. Overview As shown in FIG. 1, an exhaust duct holding member (hereinafter simply referred to as “holding member”) X is detachably attached to a window frame (not shown). An air conditioner (not shown) is disposed indoors, for example, on the floor surface, and its exhaust duct 9 is connected to and held by the holding member X. The holding member X is attached between a window with a partially open portion and the window frame. The holding member X includes an attachment unit 1 that has an exhaust port 66 (see FIG. 5) for discharging air from the air conditioner to the outside and is detachably attached to the window frame, and a shutter 3 that opens and closes a communication passage 10 (see FIG. 5) that communicates the exhaust duct 9 of the air conditioner and the exhaust port 66. Thereby, when the air conditioner is used (when the air conditioner is driven to exhaust), the shutter 3 can be opened to exhaust the air from the air conditioner, and when not in use (when the air conditioner is not driven, including the case where the exhaust duct 9 is removed), the shutter 3 can be closed to prevent the intrusion of rainwater, dust, and odors. In FIG. 5, the leading end of the lead line of the communication passage 10 is indicated by an arrow so that it can be distinguished from the lead line of the external duct 6.

[0011] As shown in Fig. 2, the attachment unit 1 includes a fixture 2 attached to the window frame and having an opening 20 for exhaust, an attachment 5 (see Fig. 1) provided at the end of the exhaust duct 9, a connector 4 for connecting to the attachment 5, an external duct 6 for covering the opening 20 (see Figs. 3 and 4) of the fixture 2 in a communicating state from the outdoor side, and a filter body 7 for suppressing the intrusion of dust and the like into the opening 20. Here, the outlet of the external duct 6 is the exhaust port 66. Note that in Fig. 2, the illustration of the attachment 5 is omitted so that the state of the opening 20 and the shutter 3 can be understood. The attachment 5 (see Fig. 1) is not an essential component. Considering the simplicity of the work during the attachment of the exhaust duct 9 and the sealing performance at the connection part with the exhaust duct 9, it is preferable to provide the attachment 5, and it is more preferable to make the attachment 5 dedicated to the fixture 2. Here, it is assumed that the attachment 5 is provided on the fixture 2. The external duct 6 is not an essential component, but considering that rainwater and the like may intrude into the opening 20 of the fixture 2, it is preferable to provide the external duct 6. Here, it is assumed that the external duct 6 is provided on the fixture 2. The filter body 7 is not an essential component, but considering the intrusion of dust and insects into the room, it is preferable to provide the filter body 7 in the communication path 10 including the opening 20. Here, it is assumed that the filter body 7 is provided on the fixture 2. Hereinafter, each part will be described. For the convenience of explanation, the shutter 3 will be described first, and then the attachment unit 1 will be described.

[0012] 2. Shutter As shown in Figs. 3 and 4, the shutter 3 has a shutter plate portion 31 sized to cover the opening 20 located in the communication path 10. The shutter plate portion 31 blocks the movement of air in the communication path 10. The shutter plate portion 31 has a shape corresponding to the shape of the opening 20. Here, it has a vertically long rectangular shape. The shutter 3 has a gripping portion 32 for sliding operation. The gripping portion 32 is provided on the shutter plate portion 31 in the sliding direction and on the open state side (this side is taken as one side of the sliding direction and is the upper side in the figure). The gripping portion 32 bends from one end of the shutter plate portion 31 to the side opposite to the outdoor side (fitting 2). As shown in the enlarged view of FIG. 5, the shutter 3 has a maintaining portion 33 for maintaining the open state. The maintaining portion 33 here is constituted by a fitting groove 330 into which the top wall portion 415 of the connecting body 4 is fitted. More specifically, the fitting groove 330 is formed between two ridge portions 331 and 332 that extend in a direction perpendicular to the sliding direction and are spaced apart in the sliding direction. Note that the ridge portion 331 on the gripping portion 32 side has an inclined surface on its gripping portion 32 side surface, and the fitting of the end surface of the top wall portion 415 can be performed smoothly.

[0013] 3. Mounting unit (1) Fitting As shown in FIGS. 2 to 4, the fitting 2 includes a first plate member 21 and a second plate member 22 that are slidable. Thus, the holding member X can be easily attached to window frames of different sizes. The fitting 2 further includes a first mounting member 23 attached to the first plate member 21 and a second mounting member 24 attached to the second plate member 22 in order to facilitate attachment to the window frame. Note that the sliding direction here is the vertical direction. Also, the "first" of the first plate member 21 and the "second" of the second plate member 22 are for convenience in distinguishing the plate members 21 and 22, and the configuration related to the first plate member 21 may also be labeled with "first" (for example, the first mounting member 23), and the configuration related to the second plate member 22 may also be labeled with "second" (for example, the second mounting member 24).

[0014] Hereinafter, mainly, FIGS. 3 and 4 will be used for explanation. The first plate member 21 has a first flat portion 211 having an opening 20 and first bent portions 212 provided at both ends orthogonal to the sliding direction in the first flat portion 211. The first flat portion 211 has a through-hole for a screw 81 for fixing the position of the slidable second plate member 22, a through-hole 214 for a screw 82 for attaching the connecting body 4 or the external duct 6, and a through-hole 215 for a screw 83 for attaching the first attachment member 23. The first flat portion 211 has a vertically long rectangular shape and has an opening 20 on the lower side. Thereby, the sliding length of the second plate member 22 can be increased, and the applicable range for attachment to the window frame can be increased. Note that the opening 20 here has a vertically long rectangular shape. The first bent portion 212 bends in an "L" shape, for example, in a direction orthogonal to the main surface of the first flat portion 211. Here, the first bent portion 212 bends outward. Thereby, the portion of the first plate member 21 that is exposed indoors mainly becomes the first flat portion 211, and the design and safety can be improved.

[0015] The second plate member 22 has a second flat portion 221 parallel to the first flat portion 211 and second bent portions 222 provided at both ends orthogonal to the sliding direction in the second flat portion 221. The second plate member 22 has a vertically long rectangular shape. The second bent portion 222 bends in an "L" shape, for example, in a direction orthogonal to the main surface of the second flat portion 221. Here, the second bent portion 222 bends outward. The second bent portion 222 is inserted into a slide groove 217 formed between the first bent portion 212 and the first flat portion 211. Thereby, the second plate member 22 is slidably supported by the first plate member 21 with a simple configuration.

[0016] The first attachment member 23 is attached to the lower end portion of the first plate member 21. The first attachment member 23 has a fitting groove portion 231 that fits with the lower rail of the window frame and an attachment portion 232 for attaching to the first plate member 21. The attachment portion 232 has a screw hole 233 for a screw 83 that passes through the through-hole 215 of the first plate member 21. The second attachment member 24 is attached to the upper end portion of the second plate member 22. The second attachment member 24 has a fitting groove portion 241 that fits with the upper rail of the window frame, and an attachment portion 242 for attaching to the second plate member 22. The attachment portion 242 has a screw hole 243 for a screw 83 that passes through the through hole 224 of the second plate member 22.

[0017] (2) Connector The connector 4 is attached to the indoor side of the first plate member 21 and holds the attachment 5. Here, the connector 4 further supports the shutter 3 slidably with the first plate member 21. The connector 4 has a frame-shaped portion 41 and a projecting portion 42.

[0018] As shown in FIG. 5, the frame-shaped portion 41 has a rectangular frame shape corresponding to the shape of the shutter 3. The frame-shaped portion 41 includes an opposing portion 411 that opposes the first flat portion 211 of the first plate member 21, and a peripheral wall portion 412 that extends from the periphery of the opposing portion 411 toward the first plate member 21. The peripheral wall portion 412 includes a bottom wall portion 413 located on the other side in the sliding direction, a pair of side wall portions 414 along the sliding direction, and a top wall portion 415 located on one side in the sliding direction. The connection body connection portion 53 of the attachment 5 attached to the end of the exhaust duct 9 is connected to the frame-shaped portion 41.

[0019] The projecting portion 42 is provided on three frame portions (the bottom wall portion 413 and the pair of side wall portions 414) excluding the frame portion (the top wall portion 415) on one side in the sliding direction in the frame-shaped portion 41. The projecting portion 42 projects in a stepped shape that widens outward from the edges on the first plate member 21 side of the bottom wall portion 413 and the pair of side wall portions 414. A support groove (support portion) 423 for slidably supporting the shutter 3 is formed between the inside of the stepped portion 421 and the first flat portion 211. Note that the support groove 423 also functions as a guide groove for sliding the shutter 3. Since there is no projecting portion 42 between the edge of the top wall portion 415 and the first flat portion 211, a gap is formed, and the shutter 3 can slide (be inserted and removed) through the gap. The protruding portion 42 has screw holes 83 for fixing the connector 4 to the first plate member 21 at both ends in the sliding direction.

[0020] (3) Attachment As shown in FIGS. 3 and 4, the attachment 5 has a duct connection portion 51 that connects to the end of the exhaust duct 9, a connector connection portion 53 that connects to the connector 4, and a connecting portion 55 that connects the duct connection portion 51 and the connector connection portion 53. The attachment 5 is provided at the end of the exhaust duct 9 and connects to the connector 4. Therefore, the attachment 5 can also be said to be an end member. The duct connection portion 51 has a cylindrical shape so as to fit around the outer periphery of the end of the exhaust duct 9. The connector connection portion 53 has a cylindrical portion 531 that is inserted through the opening 417 of the connector 4, and a contact portion 533 that protrudes outward from the end of the cylindrical portion 531 on the connecting portion 55 side and contacts the opposing portion 411 of the connector 4. The connecting portion 55 has a shape that becomes thicker from the duct connection portion 51 toward the connector connection portion 53.

[0021] (4) Filter body As shown in FIGS. 3 and 4, the filter body 7 is provided in the communication passage 10. The filter body 7 is provided on the outer surface side of the first plate member 21 of the fixture 2. Specifically, it is provided between the opening 20 (first plate member 21) and the external duct 6. The filter body 7 includes a filter 71 and a frame body 73 that supports the filter 71.

[0022] (5) External duct As shown in FIGS. 3 and 4, the external duct 6 is provided on the outdoor side of the first plate member 21. The external duct 6 has an annular plate portion 61 that is the first flat plate portion 211 and contacts the peripheral portion of the opening 20, a step portion 62 formed on the opposite side of the first plate member 21 from the inner peripheral edge of the annular plate portion 61, and a duct portion 63 formed such that the internal space faces downward from the inner peripheral edge of the step portion 62. The annular plate portion 61 has a screw hole 611 for a screw 82 for fixing the external duct 6 to the first plate material 21 in the boss portion 64. As shown in FIG. 5, the stepped portion 62 enters inward as it moves away from the annular plate portion 61. A holding groove (accommodation groove) 621 for holding (accommodating) the filter body 7 is formed by the stepped portion 62 and the first flat plate portion 211. The duct portion 63 is curved in an elbow shape that curves downward. For the duct portion 63, the inlet 65 faces the first plate material 21, and the outlet 66 is orthogonal to the first plate material 21. The outlet 66 constitutes an exhaust port (66) for discharging air from the air conditioner. In FIG. 3, for the sake of convenience, the lead lines of the inlet 65 and the outlet 66 are shown as arrows to distinguish them from the lead line of the duct portion 63. The portion of the duct portion 63 facing the opening 20 is curved so as to move away from the opening 20 as it moves from one side to the other side in the sliding direction. Thereby, the exhaust can be performed smoothly.

[0023] <Second Embodiment> The holding member X of the first embodiment was detachably attached to the window frame, but in the second embodiment, an exhaust duct holding member (hereinafter simply referred to as "holding member") Y that is directly attached to the window will be described. Note that members of the second embodiment with the same names as those of the first embodiment have the same effects as those of the first embodiment, and the description thereof may be omitted in some cases. 1. Outline As shown in FIG. 6, the holding member (hereinafter simply referred to as "holding member") Y is detachably attached by using the opening 1092 of the glass material 1091 of the window 1009. The exhaust duct 1093 of an air conditioner (not shown) is connected to the holding member Y. The holding member Y includes a mounting unit 1001 that has an exhaust port 1065 (see FIG. 10) for discharging air from the air conditioner to the outside and is detachably attached to the window, and a shutter 1003 that can open and close a communication passage 1010 (see FIG. 9) that communicates with the exhaust duct 1093 of the air conditioner and the exhaust port 1065. The holding member Y includes a lid 1103 for improving the airtightness of the communication passage 1010 when the shutter 1003 is removed and the air conditioner is operated.

[0024] As shown in FIGS. 7 and 8, the mounting unit 1001 includes a fixture 1002 attached to the opening 1092 of the glass material 1091 and having a space for the communication passage 1010 inside, an attachment 1005 for connecting the exhaust duct 1093 to the fixture 1002, an external duct 1006 that covers the opening 1020 of the fixture 1002 in a communicating state from the outdoor side, and a filter body 1007 provided in the communication passage 1010 including the opening 1020. Note that the attachment 1005, the external duct 1006, and the filter body 1007 are not essential components, but it is preferable to provide them. Hereinafter, each part will be described.

[0025] 2. Mounting unit (1) Fixture As shown in FIGS. 8 to 9, the fixture 1002 includes a first member 1021 and a second member 1023 that sandwich the peripheral portion of the opening 1092 of the glass material 1091. The fixture 1002 includes a first buffer material 1024 disposed between the first member 1021 and the glass material 1091, and a second buffer material 1025 disposed between the second member 1023 and the glass material 1091.

[0026] The first member 1021 has a first cylindrical portion 1211 that passes through the opening 1092, and a first flange portion 1212 that projects radially outward from the end of the first cylindrical portion 1211. The first cylindrical portion 1211 is cylindrical. As shown in FIGS. 9 and 10, the first cylindrical portion 1211 has a male screw portion 1213, a shutter mounting portion 1214, and a cylindrical portion 1215 along the cylinder axis direction. Hereinafter, mainly with reference to FIG. 10, the description will be made. The male screw portion 1213 is located on the side of the first flange portion 1212, and a male screw is formed on its outer peripheral surface. Note that the female screw portion 1233 of the second member 1023 is screwed into the male screw portion 1213. The first cylindrical portion 1211 has an inlet 1216 for receiving the shutter 1003 on the upper side corresponding to the shutter mounting portion 1214, and a concave portion 1217 formed on the inner peripheral surface of the first cylindrical portion 1211 for fixing the shutter 1003. The shutter mounting portion 1214 is formed in a stepped shape between the cylindrical portion 1215 and the male screw portion 1213. The inlet 1216 is provided along the circumferential direction in the upper half region of the first cylindrical portion 1211 to receive the disc-shaped shutter 1003. The concave portion 1217 is constituted by a recess between a pair of ridge portions 1217a, 1217b (see FIG. 10) formed at intervals in the cylinder axis direction and protruding toward the cylinder axis. The interval between the pair of ridge portions 1217a, 1217b corresponds to the dimension of the shutter 1003 in the cylinder axis direction. Thereby, the shutter 1003 fitted in the concave portion 1217 is fixed in a positioned state with respect to the cylinder axis direction. Also, the pair of ridge portions 1217a, 1217b are continuously provided over the entire circumference. Thereby, the insertion tip of the shutter 1003 can be guided to the bottom portion of the concave portion 1217. The cylindrical portion 1215 has a protruding portion 1218 that protrudes outward in the radial direction so as to move within the groove portion 1053 (see FIGS. 7 and 8) of the attachment 1005. The protruding portions 1218 are provided at two positions facing each other across the cylinder axis. The protruding portion 1218 is located closer to the center side than the male screw portion 1213 in the radial direction. Thereby, the screwing together of the first member 1021 and the second member 1023 is not interfered with.

[0027] The first flange portion 1212 has an opposing portion 1220 formed on the outer peripheral side of the first cylindrical portion 1211 and extending in the radial direction so as to face the glass material 1091, a groove portion 1221 recessed from the opposing portion 1220 to the side opposite to the glass material 1091 (the outdoor side), and a bent portion 1222 bent outward from the outer peripheral edge of the opposing portion 1220 to the outdoor side. The opposing portion 1220 extends radially outward from the outdoor-side end of the first cylindrical portion 1211 and is annular. Thereby, it faces the entire circumferential region of the peripheral portion of the opening 1092, and the sealing performance can be improved. As shown in FIGS. 7 and 8, the opposing portion 1220 has boss holes for accommodating screws 1081 for attaching the external duct 1006 at intervals in the circumferential direction. Note that the first member 1021 houses the filter body 1007 therein and is attached to the glass material 1091 with the external duct 1006 attached thereto.

[0028] The groove portion 1221 is the opposing portion 1220 and is provided so as to be located on the outer peripheral side of the opening 1092 of the glass material 1091. Thereby, the portion inside (on the cylinder axis side) the groove portion 1221 in the opposing portion 1220 also faces the glass material 1091, and the sealing performance can be further improved. Here, the groove portion 1221 is annular when viewed from the cylinder axis direction of the first cylindrical portion 1211. The first cushioning material 1024 is inserted into the groove portion 1221. Thereby, damage to the glass material 1091 can be prevented and the sealing performance between the glass material 1091 and the first member 1021 can be enhanced. The bent portion 1222 has a cylindrical shape when viewed from the outdoor side in the cylinder axis direction. The bent portion 1222 fits with the external duct 1006 such that its outer peripheral surface abuts against the inner peripheral surface of the outer cylindrical portion 1613 of the external duct 1006. Note that the upper end portion of the bent portion 1222 has a convex portion 1224 that fits into a groove 1616 (see FIGS. 7 and 8) of the outer cylindrical portion 1613 of the external duct 1006. Thereby, the external duct 1006 is positioned in the circumferential direction. The first flange portion 1212 is provided on the indoor side rather than the outdoor-side end of the first cylindrical portion 1211 and has a stepped portion 1225 on the inner peripheral surface of the outdoor-side end of the first cylindrical portion 1211. The filter body 1007 is disposed on this stepped portion 1225 and the inner cylindrical portion of the external duct 1006 is fitted therein. Thereby, intrusion of rainwater into the first member 1011 can be prevented.

[0029] The second member 1023 has a second cylindrical portion 1231 and a second flange portion 1232. The second cylindrical portion 1231 has an internal thread portion 1233 on its inner circumferential surface that engages with the external thread portion 1213 of the first member 1021. The second flange portion 1232 extends radially from the outdoor-side end of the second cylindrical portion 1231 and faces the glass material 1091. The second flange portion 1232 is annular when viewed in the cylinder axis direction. The first flange portion 1212 and the second flange portion 1232 sandwich the glass material 1091 in the indoor-outdoor direction (both sides in the thickness direction of the glass material 1091) when the internal thread portion 1233 of the second cylindrical portion 1231 engages with the external thread portion 1213 of the first member 1021. At this time, the second flange portion 1232 abuts against the glass material 1091 via the second cushioning material 1025. Thereby, it is possible to prevent the glass material 1091 from being damaged and to enhance the sealing performance between the second member 1023 and the glass material 1091.

[0030] (2) Cushioning material This will mainly be described with reference to FIGS. 7 and 8. The first cushioning material 1024 prevents the window from being damaged by the first flange portion 1212 of the first member 1021 coming into direct contact with the glass material 1091. For the first cushioning material 1024, for example, an elastically deformable sealing member can be used. The first cushioning material 1024 can use, for example, an O-ring-shaped gasket. The first cushioning material 1024 is larger than the groove portion 1221 of the first member 1021. Thereby, when the first member 1021 is pressed toward the glass material 1091 side, the first cushioning material 1024 elastically deforms to improve the sealing performance. For this reason, the first cushioning material 1024 forms an airtight body. The second cushioning material 1025 prevents the window from being damaged by the second flange portion 1232 of the second member 1023 coming into direct contact with the glass material 1091. For the second cushioning material 1025, for example, an elastically deformable sealing member can be used. The second cushioning material 1025 can use a thin-plate-shaped gasket. When the second member 1023 is pressed toward the glass material 1091 side, the second cushioning material 1025 elastically deforms to improve the sealing performance. For this reason, the second cushioning material 1025 forms an airtight body.

[0031] (3) Attachment As shown in FIGS. 7 and 8, the attachment 1005 has a small-diameter cylindrical portion 1051 that engages with the exhaust duct 1093 and a large-diameter cylindrical portion 1052 that fits into the first cylindrical portion 1211 of the first member 1021. The attachment 1005 is provided at the end of the exhaust duct 1093 and is connected to the first cylindrical portion 1211. Therefore, the attachment 1005 can also be said to be an end member. The large-diameter cylindrical portion 1052 has a groove portion 1053 for the protruding portion 1218 of the first cylindrical portion 1211 of the first member 1021. As shown in FIG. 9, the groove portion 1053 has a regulating groove portion 1055 that restricts the movement of the protruding portion 1218 in the direction in which the exhaust duct 1093 and the fixture 1002 are separated, and a guiding groove portion 1056 that guides the protruding portion 1218 within the regulating groove portion 1055. Note that the protruding portion 1218 can engage with the regulating groove portion 1055 to attach the attachment 1005 to the fixture 1002, thereby forming a locking portion. For example, the regulating groove portion 1055 extends in the circumferential direction, the guiding groove portion 1056 extends in the cylinder axis direction, and the overall shape is "L" shaped. Note that the groove portion 1053 is provided at two opposing portions sandwiching the cylinder axis.

[0032] (4) External Duct The external duct 1006 is provided on the outdoor side of the first member 1021. The external duct 1006 has an annular fitting portion 1061 that fits into the first flange portion 1212 of the first member 1021, and a duct portion 1063 formed such that the internal space faces downward from the inner peripheral edge of the annular fitting portion 1061. As shown in FIG. 10, the annular fitting portion 1061 has an annular opposing portion 1611 that faces the first flange portion 1212 of the first member 1021, an inner cylindrical portion 1612 that extends from the inner peripheral edge of the opposing portion 1611 toward the first member 1021 side, and an outer cylindrical portion 1613 that extends from the outer peripheral edge of the opposing portion 1611 toward the first member 1021 side.

[0033] The first flange portion 1212 of the first member 1021 fits between the inner cylindrical portion 1612 and the outer cylindrical portion 1613 of the annular fitting portion 1061. The opposing portion 1611 has screw holes 1615 for screws 1081 that connect the first member 1021 and the external duct 1006 at intervals in the circumferential direction. The indoor-side end face of the inner cylindrical portion 1612 abuts against the filter body 1007 disposed within the first member 1021. Thereby, the filter body 1007 can be fixed in a positioned state within the communication path 1010. The outer cylindrical portion 1613 has a groove 1616 that fits with the convex portion 1224 of the first flange portion 1212 of the first member 1021. The groove 1616 extends parallel to the cylindrical axis of the outer cylindrical portion 1613. The duct portion 1063 curves in an elbow shape that curves downward. For the duct portion 1063, the inlet 1064 faces the first member 1021, and the outlet 1065 is orthogonal to the first member 1021. The outlet 1065 constitutes the discharge port (1065) of the mounting unit 1001. The portion of the duct portion 1063 that faces the opening 1020 curves so as to move away from the opening 1020 as it goes downward. Thereby, exhaust can be performed smoothly.

[0034] (5) Filter body The filter body 1007 has a shape corresponding to the cross-sectional shape of the communication path 1010. Here, it has a circular shape. As described above, the filter body 1007 is housed in the stepped portion 1225 of the first cylindrical portion 1211 of the first member 1021, and is configured such that the peripheral edge of the filter body 1007 abuts against the stepped portion 1225.

[0035] 3. Shutter The shutter 1003 is inserted into the communication path 1010 so as to be insertable and removable with respect to the communication path 1010. The shutter 1003 has a shutter plate portion 1031 sized to close the communication path 1010. When the shutter 1003 is inserted into the communication path 1010, the shutter plate portion 1031 blocks the movement of air within the communication path 1010, and when the shutter 1003 is withdrawn from the communication path 1010, the communication path 1010 is opened and air movement becomes possible. The shutter plate portion 1031 has a shape corresponding to the cross-sectional shape of the communication path 1010. As shown in FIG. 8 in the cross-section of the communication passage 1010, the shutter plate portion 1031 has a front portion 1311 that closes the insertion-side half (the lower half in the figure) and a rear portion 1312 that closes the extraction-side half (the upper half in the figure). Here, the communication passage 1010 is formed inside the first cylindrical portion 1211 of the first member 1021 and has a cylindrical shape. Therefore, the front portion 1311 and the rear portion 1312 are semi-circular. In the closed state of the communication passage 1010, the front portion 1311 fits into the concave portion 1217 of the shutter mounting portion 1214 of the first cylindrical portion 1211, and the rear portion 1312 fits into the receiving port 1216 of the shutter mounting portion 1214. For this reason, the radius of the front portion 1311 is configured to be smaller than the radius of the rear portion 1312. As shown in FIG. 7, the shutter 1003 has a rib portion 1036 for reinforcing the shutter plate portion 1031 on the outdoor side. The shutter 1003 has a front overhanging portion 1034 that projects outward from the peripheral edge of the front portion 1311. The dimension in the cylinder axis direction of the combined front overhanging portion 1034 and the front portion 1311 corresponds to the dimension in the cylinder axis direction of the concave portion 1217 of the shutter mounting portion 1214. The shutter 1003 has a rear overhanging portion 1035 that projects inward and outward from the peripheral edge of the rear portion 1312. The receiving port 1216 is covered (closed) by the rear overhanging portion 1035. The shutter 1003 has a gripping portion 1032 for operation. As shown in FIG. 8, the gripping portion 1032 has a narrow portion 1037 that extends in the extraction direction from the rear overhanging portion 1035, and a wide portion 1038 that further extends from the tip of the narrow portion 1037 and has a through hole at the center. The user mainly grips the wide portion 1038.

[0036] 4. Cover The cover 1103 closes the receiving port 1016 of the first member 1021 from the outside without closing the communication passage 1010. Note that the cover 1103 is not an essential component, but it is more convenient to have it because it can prevent exhaust leakage from the first member 1021 when attached during the operation of the air conditioner. In addition, it can prevent the exposure of the receiving port 1016 during the operation of the air conditioner and enhance the design. As shown in FIGS. 7 and 8, the lid 1103 is configured such that the disk-shaped shutter plate portion 1031 of the shutter 1003 is an arcuate ridge portion 1105. That is, the lid 1103 has a gripping portion 1032, an overhanging portion 1035, and a ridge portion 1105. The overhanging portion 1035 corresponds to the rear overhanging portion 1035 of the shutter 1003 and abuts against the peripheral portion of the receiving port 1016 from the outside. Thereby, the sealing performance between the receiving port 1016 and the lid 1103 can be improved. The ridge portion 1105 protrudes from the overhanging portion 1035 to the side opposite to the gripping portion 1032. The overhanging portion 1035 and the ridge portion 1105 are arc-shaped corresponding to the arc-shaped receiving port 1016 when viewed in the cylinder axis direction of the first cylindrical portion 1211. Thereby, the position of the lid 1103 in the cylinder axis direction of the first cylindrical portion 1211 is regulated.

[0037] As described above, the first and second embodiments have been described, but the present invention is not limited to these embodiments, and for example, the following modifications may be possible. Also, combinations of each embodiment, modification, and modifications may be possible. In addition, examples not described in the embodiments and modifications, and design changes within the scope not departing from the gist are also included in the present invention. Note that the partition plate of Patent Document 1 has a problem different from the above-described problems. That is, the partition plate of Patent Document 1 can be provided in a window that opens and closes by sliding two glass materials left and right, respectively, but it is difficult to provide it in a window that opens and closes in the front-rear direction by pivotally supporting one end of the glass material on the upper side, lower side, left side, or right side. The duct holding member of the second embodiment can solve this problem because it has the following configuration. That is, the duct holding member in the second embodiment is a duct holding member that can be connected to the exhaust duct of the air conditioner and is provided on the window, and includes a first member having a cylindrical portion that inserts through the opening of the window from the outdoor side, and a second member that is connected to an end member provided at the end of the exhaust duct. The second member is characterized in that it is connected to the first member while sandwiching the window between the first member. This makes it easy to attach the duct holding member to a window that opens and closes by having one end on the upper, lower, left, or right side pivotally supported.

[0038] <Modification example> 1. Exhaust port The exhaust ports 66 of the first embodiment and 1065 of the second embodiment are constituted by the outlets 66, 1065 of the external ducts 6, 1006. However, the holding member may not include an external duct. When not including an external duct, the opening 20 of the fixture 2 (the first plate member 21) in the first embodiment and the opening 1020 of the fixture 1002 (the outdoor-side end of the first cylindrical portion 1211 of the first member 1021) in the second embodiment constitute the exhaust port.

[0039] 2. Communication path The entrance of the communication path is formed at the end of the exhaust ducts 9, 1093 in the first and second embodiments. However, when the end of the exhaust duct is connected to an attachment or the like in a state of being exposed to the outside, for example, the entrance of the communication path is constituted by the connection-side end of the attachment. Thus, the entrance of the communication path varies depending on the connection method of the exhaust duct to the attachment, but it may also be an opening through which air from the air conditioner enters the mounting unit.

[0040] 3. Shutter The shutters 3, 1003 of the embodiment are provided on the indoor side in the communication paths 10, 1010, but it is only necessary to be able to open and close the communication paths 10, 1010. For example, it may be provided on the outdoor side or may be provided at two locations on the indoor side and the outdoor side. The shutter 3 of the first embodiment is provided between the fixture 2 and the connector 4. However, it suffices if the communication passage 10 can be opened and closed. For example, when a connector is provided, it may be provided on the connector, when an attachment is provided, it may be provided on the attachment, or when an external duct is provided, it may be provided on the external duct. The shutter 1003 of the second embodiment was provided on the first cylindrical portion 1211 of the first member 1021. However, it suffices if the communication passage 1010 can be opened and closed. For example, it may be provided at a portion where the first member and the second member overlap, or when an attachment is provided, it may be provided on the attachment.

[0041] 4. Filter body The filter bodies 7, 1007 are arranged on the outdoor side with respect to the shutters 3, 1003 in the communication passages 10, 1010, but may be arranged on the indoor side. The filter bodies 7, 1007 are arranged so as to be located within the communication passages 10, 1010. However, it suffices if it is possible to prevent (suppress) the entry of dust, insects, etc. into the room. For example, it may be provided so as to cover the outlet from the outside of the communication passage.

[0042] 5. Attachment The attachments 5, 1005 are provided at the ends of the exhaust ducts 9, 1093. However, for example, the attachment may be fixedly provided to the fixture, and the exhaust duct may be inserted into the connection port of the fixed attachment for connection. The attachment 1005 of the second embodiment is provided with a groove portion 1053, and the first cylindrical portion 1211 of the first member 1021 is provided with an engaging portion (projecting portion 1218). However, an engaging portion may be provided on the attachment and a groove portion may be provided on the first cylindrical portion 1211.

[0043] 6. Fixture The fixture 1002 of the second embodiment includes a first member 1021 that inserts through the opening 1092 from the outdoor side, and a second member 1023 that sandwiches the glass material 1091 with the first member 1021. However, the first member may be configured to insert through the opening 1092 from the indoor side, and the glass material may be sandwiched with the second member on the outdoor side. In addition, although the fixture 1002 was attached to the glass material 1091, it may be attached to a metal plate material or a wooden plate material that constitutes a window, or it may be attached to a wall or the like. In the attachment unit 1001 of the second embodiment, the fixture 1002 is attached to the window. However, for example, a support for supporting the fixture 1002 may be provided. Thereby, breakage such as cracking of the window can be prevented. Examples of the support include a suspension tool for suspending the second member 1023 from above such as a ceiling, and a support for supporting the first member 1021, the second member 1023, and the attachment 1005 from below such as a floor surface or a lower frame portion of a window frame (there are plate-like bodies, rod-like bodies, etc.).
