  • the first projecting portion 42c is inserted into the recess 37a formed in the mounting portion 37, and the first projecting portion 42c is hooked on the inner edge of the recess 37a. Therefore, the first projecting portion 42c can be stably hooked to the placing portion 37. As shown in FIG.
  • the housing 21 has the second projecting portion 36 projecting upward from the placing portion 37 .
  • a hole portion 42d into which the second projecting portion 36 is inserted is formed in the lower surface of the base portion 42a of the handle portion 42 . Therefore, the filter 40 can be further prevented from moving forward with respect to the housing 21 by the second projecting portion 36 being caught on the inner surface of the hole portion 42d. Accordingly, it is possible to further prevent the filter 40 from unintentionally coming off the housing 21 .
  • the housing 21 has the support projection 38 with which the supported end portion 43, which is the lower end portion of the front end portion of the handle portion 42, is hooked from behind. Therefore, forward movement of the filter 40 with respect to the housing 21 can be further suppressed. Accordingly, it is possible to further prevent the filter 40 from unintentionally coming off the housing 21 . Further, as described above, when the filter 40 is removed from the housing 21, if the handle portion 42 is grasped with the fingers HF and pulled forward, the handle portion 42 extends in the horizontal direction Y with the supported end portion 43 as a fulcrum. Easy to turn around.
  • the base portion 42a and the first projecting portion 42c can be easily lifted upward to facilitate the engagement between the first projecting portion 42c and the mounting portion 37 and the engagement between the second projecting portion 36 and the hole portion 42d. Easy to remove. Therefore, the filter 40 can be easily removed from the housing 21 .
  • the indoor unit 20 is arranged at a relatively high position on the wall surface WS of the room, when removing the filter 40 from the housing 21, the operator extends his arm upward and pulls the handle 42 with his finger HF. to pull the filter 40 forward. As a result, even if the operator intends to simply pull the handle portion 42 forward, the handle portion 42 is likely to be pulled forward and downward. Therefore, an operator who removes the filter 40 from the housing 21 tends to unintentionally turn the handle portion 42 around the supported end portion 43 as a fulcrum. Therefore, it is easier to remove the filter 40 from the housing 21 .
  • part of the air sucked into the housing 21 by the blower 23 passes through the insertion port 50 .
  • the insertion port 50 can also be used as a suction port for sucking air into the housing 21 . Therefore, air can be easily sucked into the housing 21 .
  • the size of the cover wall portion 42b is set to the minimum size within the range where the line of sight LS of the user can be blocked, air can be more easily sucked into the housing 21 through the insertion opening 50 .
  • the outer shell member 30 includes a front wall portion 32 that is positioned in front of the heat exchanger 22 and constitutes a front outer shell of the outer shell of the housing 21, and a front wall portion a pair of side wall portions 33a and 33b projecting rearward from both ends in the left-right direction Y of the housing 21 and constituting outer shells on both sides in the left-right direction Y of the outer shell of the housing 21, and integrally formed therewith. molded. Therefore, when the indoor unit 20 is viewed from the front and when the indoor unit 20 is viewed from both the left-right direction Y, the design of the indoor unit 20 can be improved favorably.
  • the front wall portion 32 of the outer shell member 30 can be formed integrally with the pair of side wall portions 33a and 33b in this manner because it is not necessary to open a part of the front wall portion 32 as a separate member as described above. It's for.
  • the outer shell member 30 also has a lower wall portion 34 that constitutes the lower outer shell of the outer shells of the housing 21 . Therefore, the design of the indoor unit 20 when viewed from below can also be favorably improved.
  • the filter 140 has a portion that covers the heat exchanger 22 from the front as in the conventional indoor unit 120
  • the lower end of the portion that covers the heat exchanger 22 from the front of the filter 140 is attached to the housing 121. It is necessary to prevent the air sucked into the housing 121 from the suction port 20 a from flowing into the heat exchanger 22 through the gap between the filter 140 and the housing 121 .
  • the handle portion 142 is provided at the lower end portion of the portion of the filter 140 that covers the heat exchanger 22 from the front, the case 121 is in the way, making it difficult to grasp the handle portion 142 .
  • the handle portion 142 is arranged at a position above the lower end portion of the portion of the filter 140 that covers the heat exchanger 22 from the front, as described above.
  • the filter 40 does not have a portion that covers the heat exchanger 22 from the front. Therefore, the front end portion of the filter 40 may be attached to the housing 21 in front of the insertion port 50 . That is, the filter 40 can cover the suction port 20a from below without disposing the front end portion of the filter 40 inside the housing 21 .
  • the front end of the filter main body 41 is provided with a handle 42 having an easy-to-grip shape and the handle 42 is attached to the housing 21, the flow of the air after being sucked into the housing 21 is prevented by the handle 42. 42 does not interfere.
  • the position and shape of the handle portion 42 can be set to a position and shape suitable for gripping the filter 40 while facilitating the flow of air inside the housing 21 . Therefore, the work of attaching and detaching the filter 40 to and from the housing 21 can be performed more easily.
  • the insertion opening of the housing of the indoor unit may be formed at any position on the housing as long as it opens forward and allows the filter to be inserted from the outside of the housing of the indoor unit.
  • the insertion opening may be formed in the central portion of the housing in the vertical direction Z, or may be formed in the lower portion of the housing. Only one insertion opening may be formed, or three or more insertion openings may be formed. A plurality of filters may be inserted into one insertion port.
  • the shape and type of the filter placed between the suction port and the heat exchanger are not particularly limited.
  • the filter inserted into the housing through the insertion opening has a portion that covers the heat exchanger from the front.
  • the handle of the filter may be arranged at any position on the filter and may have any shape.
  • the cover wall portion of the handle portion of the filter may only partially overlap the insertion opening when viewed from the front.
  • the shape of the housing of the indoor unit is not particularly limited.
  • the upper wall portion of the housing may not have the upper wall inclined portion.
  • the outer shell member may have any configuration as long as it constitutes a part of the outer shell of the housing.
  • the outer shell member does not have to be integrally molded. That is, the outer shell member may be configured by combining a plurality of members.
  • the outer shell member may have an outer shell member main body and a decorative part attached to the outer shell member main body.
