In this way, the fastening member 5 is easily accessible, and thus the maintainability of the air conditioning indoor unit 1 is improved.
(4-3)
The dew condensation water flowing in the outlet portion 31 is low in temperature. Therefore, if the heat insulation is not ensured on the outer surface of the outlet portion 31, dew condensation may occur on the outer surface of the outlet portion 31. Further, in the case of directly fastening the outlet portion 31 and the 1 st member 50, the 1 st member 50 may dew condensation.
As shown in fig. 2B, the air conditioning indoor unit 1 of the present invention includes a heat insulating member 70. The heat insulating member 70 covers the outer surface of the outlet 31. This ensures the heat insulation of the outer surface of the outlet portion 31.
As shown in fig. 2A, the 1 st member 50 is fixed to the main body 35 so as not to directly contact the outlet portion 31. This ensures the heat insulation of the 1 st member 50.
As shown in fig. 3 and 15, the 1 st member 50 and the 2 nd member 60 in the present invention are disposed so that the fastening work can be performed in the space outside the heat insulating member 70. Accordingly, since the fastening operation can be performed without a step such as a removal operation of the heat insulating material 70, a reduction in maintainability can be suppressed.
With the above configuration, the air conditioning indoor unit 1 of the present invention can ensure the heat insulation properties of the outer surface of the outlet portion 31 and the 1 st member 50, and can suppress a reduction in maintenance properties.
(4-4)
In order to allow the dew condensation water to flow to the outside of the target space SP, the drain hose 40 extends rearward and downward as viewed from the front side of the air conditioning indoor unit 1 and is connected to the 1 st drain pan 30 a. The 1 st member 50 and the 2 nd member 60 are fixed to the main body 35 and the 1 st end portion 41a along the drain hose 40 extending in the back-and-down direction. Therefore, when the 1 st plate-like portion 50a and the 2 nd plate-like portion 60a are not inclined with respect to the 1 st adjacent portion 50b and the 2 nd adjacent portion 60b (when the 1 st plate-like portion 50a and the 2 nd plate-like portion 60a are flush with the 1 st adjacent portion 50b and the 2 nd adjacent portion 60b), the fastening member 5 needs to be fastened from the front upper direction when the 1 st member 50 and the 2 nd member 60 are fastened by the fastening member 5, and thus, the maintainability is lowered.
As shown in fig. 9 and 12, the 1 st plate-like portion 50a and the 2 nd plate-like portion 60a in the present invention are inclined with respect to the 1 st adjacent portion 50b and the 2 nd adjacent portion 60 b. Specifically, the 1 st plate-like portion 50a and the 2 nd plate-like portion 60a are inclined such that the fastening direction of the fastening member 5 is along the horizontal direction (perpendicular to the floor surface of the target space SP) when fastened by the fastening member 5. When the 1 st plate-like portion 50a and the 2 nd plate-like portion 60a are inclined in this manner, the fastening member 5 can be easily fastened because the removal direction and the fastening direction of the fastening member 5 are along the horizontal direction as shown in fig. 15. This improves the maintainability of the air conditioning indoor unit 1.
(4-5)
As shown in fig. 3 and 15, the fastening member 5 of the present invention is disposed in the space below the 1 st drain pan 30a when viewed from the front side of the air conditioning indoor unit 1. In this way, the air conditioning indoor unit 1 of the present invention can save space in the left-right direction in the three-dimensional space of the casing 100 by fastening the 1 st member 50 and the 2 nd member 60 to the space below the 1 st drain pan 30 a.

As described above, the fastening member 5 penetrates the 2 nd through hole 502 and the 3 rd through hole 601, and thereby the 1 st member 50 and the 2 nd member 60 are fastened. At this time, when the 1 st member 50 is fixed to the 1 st drain pan 30a, the 2 nd member 60 is fixed to the drain hose 40, and the position of the 2 nd through hole 502 and the position of the 3 rd through hole 601 do not overlap, the positions of the 2 nd through hole 502 and the 3 rd through hole 601 need to be adjusted by twisting the drain hose 40 or the like. In the case where the adjustment of the positions of the 2 nd penetration hole 502 and the 3 rd penetration hole 601 is performed by this method, the reliability of the drain hose 40 may be lowered.
The fitting portion 60c of the present invention is loosely fitted to the drain hose 40. Thereby, the 2 nd member 60 can revolve in the rotation direction of the drain hose 40. Therefore, even when the positions of the 2 nd through hole 502 and the 3 rd through hole 601 do not overlap, the positions of the 2 nd through hole 502 and the 3 rd through hole 601 can be easily adjusted by rotating the 2 nd member 60. With the above configuration, the air conditioning indoor unit 1 according to the present invention suppresses a decrease in reliability of the drain hose 40 and improves maintainability.
(5) Modification example
(5-1) modification A
In the above embodiment, the following example is explained: for the purpose of adjusting the fastening direction of the fastening member 5 in the horizontal direction at the time of maintenance, the 1 st plate-like portion 50a is inclined with respect to the 1 st adjacent portion 50b, and the 2 nd plate-like portion 60a is inclined with respect to the 2 nd adjacent portion 60 b. However, the configuration of the 1 st plate-like portion 50a and the 2 nd plate-like portion 60a in the present invention is not limited to this, and for example, the 1 st plate-like portion 50a may be inclined with respect to the 1 st adjacent portion 50b and the 2 nd plate-like portion 60a may not be inclined with respect to the 2 nd adjacent portion 60b, or the 1 st plate-like portion 50a may not be inclined with respect to the 1 st adjacent portion 50b and the 2 nd plate-like portion 60a may be inclined with respect to the 2 nd adjacent portion 60 b.
In the former case, the 2 nd member 60 is fixed to the drain hose 40 at an angle perpendicular to the floor surface of the target space SP, whereby the fastening direction of the fastening member 5 is along the horizontal direction. In the latter case, the 1 st member 50 is fixed to the 1 st drain pan 30a at an angle perpendicular to the ground surface of the target space SP, whereby the fastening direction of the fastening member 5 is along the horizontal direction.
In this way, even when one of the 1 st member 50 and the 2 nd member 60 is not inclined, the angle at which the 1 st member 50 or the 2 nd member 60 is fixed can be adjusted, thereby improving the maintainability.
While the embodiments of the present invention have been described above, it is to be understood that various changes in the form and details may be made therein without departing from the spirit and scope of the present invention as set forth in the appended claims.
