  Hereinafter, an air conditioner according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, an air conditioner 10 according to an embodiment of the present invention can be used by being attached to, for example, an indoor wall 11 or the like. In the following description, with the air conditioner 10 attached to the wall 11, the ceiling side is “upper” and the floor side is “lower”. Further, the description will be made assuming that the indoor side is “front” and the wall 11 side is “rear” with respect to the wall 11.

  As shown in FIG. 1 and FIG. 2, the air conditioner 10 has a housing 20 as an external part that covers the inside so that the inside of the air conditioner 10 cannot be seen. An open panel 24a is provided on the front surface. The open panel 24a is held at the lower part of the front cover 24 and slides forward and upward during operation to form an air inlet 21 (211) for sucking indoor air. As the air suction port 21, in addition to the front air suction port 211 provided in a louver shape on the front surface of the housing 20 and inside the open panel 24 a in this way, the upper side provided on the upper side of the housing 20. An air inlet 212 is provided. The front air inlet 211 and the upper air inlet 212 are provided with filters (not shown) that remove dust and the like in the air to be sucked. The open panel 24a improves the appearance of the air conditioner 10 by closing the air inlet 211 when stopped.

  The air outlet 22 is provided on the lower surface of the housing 20 and opens downward. The air outlet 22 is provided with an up-and-down air direction plate 23 that can be opened and closed up and down. The vertical wind direction plate 23 opens downward during operation, and the vertical wind direction can be adjusted. The vertical wind direction plate 23 is closed when the operation is stopped. In addition, left and right wind direction plates (not shown) that can rotate in the left and right directions are provided, and the wind direction in the left and right directions can be adjusted. The housing 20 has an open rear side surface and is attached to the wall 11 via a mounting plate 12 that is a rectangular metal plate.

  As shown in FIG. 2, a cross-flow type blower fan 13 is disposed in the central portion of the housing 20. A heat exchanger 14 is arranged above the blower fan 13 so as to surround the fan. The heat exchanger 14 has a front heat exchanger and a rear heat exchanger. The front heat exchanger and the rear heat exchanger are arranged so that the upper part is close and the lower part is separated, and are arranged in a so-called inverted V shape.

  Therefore, when the blower fan 13 rotates and sucks the outside air, the outside air flows from the front air inlet 211 and the upper air inlet 212 of the housing 20 (see arrows A1, A2, and A3 in FIG. 2), and the heat exchanger 14 And is exchanged with the refrigerant for heat exchange and discharged into the room through the air outlet 22 (see arrows B1 and B2 in FIG. 2). A dew tray 15 that receives condensed water dripping from the heat exchanger 14 is provided below the heat exchanger 14.

  Next, the mounting structure of the molding 30 will be described with reference to FIGS. As shown in FIG. 3, the molding 30 is attached between the grill decoration plate 27 provided on the front cover 24 of the air conditioner 10. The molding 30 is obtained by decorating, for example, a resin extrusion-molded product by chromium plating or the like. Although not shown in FIG. 4, as described above, the open panel 24 a is provided on the front side of the front cover 24, and the upper end of the open panel 24 a is the top of the grill decoration plate 27 when the air conditioner 10 is stopped. Close to fit. The molding 30 is provided at the boundary between the open panel 24a and the grill decoration plate 27, thereby improving the appearance. As shown in FIG. 4, the grill decoration plate 27 has a claw 27 a on the back surface thereof, and is engaged with and attached to a hole (not shown) provided on the upper surface of the front cover 24. A rib 25 is provided on the rear surface of the grill decoration plate 27, and a recess 36 of the molding 30 is fitted therein as will be described in detail later. A groove portion 26 is provided on the back surface of the grill decoration plate 27, and an end straight portion 321 of the molding 30 is fitted therein as will be described in detail later. And the bending part 32 of the molding | mall 30 is pressed by the grill decorating board 27 side by the corner | angular part 24b of the front cover 24 shown in FIG.

  As shown in FIG. 6A, the molding 30 is an elongated linear member formed by extrusion molding, and bent portions 32 corresponding to the shape of the front cover 24 are provided at both ends of the linear portion 31. Furthermore, an end straight portion 321 is provided on each end side of the bent portions 32. The cross-sectional shape of the molding 30 is provided in the vertical direction so as to face the external appearance part 33 having a substantially semicircular cross section toward the part external appearance side, that is, the front side of the front cover 24, and the external appearance part 33 at a predetermined interval. The presser part 34 has a bent part 35 that connects one end side of the external part 33 and the presser part 34 to each other. The recess 36 includes an outer appearance portion 33, a presser portion 34, and a bent portion 35.

  The presser portion 34 is chamfered at a connection portion with the bent portion 35 to provide a chamfered portion 341. Further, the height H1 of the presser portion 34 is smaller than the height H2 of the external appearance portion 33. That is, the upper surface 342 of the presser part 34 is at a position lower than the upper surface 331 of the outer appearance part 33, and when viewed from the outer appearance part 33 side (from the front), the presser part 34 is hidden behind the outer appearance part 33 and cannot be seen.

  As shown in FIG. 7A, in the straight portion 31 of the molding 30, the rib 25 extending downward from the grille decorative plate 27 is inserted into the concave portion 36 of the molding 30 from above. For this reason, even if an external force that pulls the molding 30 forward from the front cover 24 acts, the molding 30 can be prevented from being peeled off.

  FIG. 7B shows the state of the molding 30 at the end 25 a of the rib 25 that is in the vicinity of the bent portion 32 of the molding 30. The molding 30 is bent at the bending portion 32 so that the appearance portion 33 is on the outer side and the pressing portion 34 is on the inner side, corresponding to the shape of the front cover 24. At this time, when the molding 30 is bent toward the presser part 34, the presser part 34 is compressed and deformed inward (see arrow C in FIG. 7B). As a result, the rib 25 of the grill decoration plate 27 is fastened and fixed by the rear surface 332 and the pressing portion 34 of the outer appearance portion 33, so that the molding 30 is securely fixed to the grill decoration plate 27.

  When the height H1 of the presser portion 34 (see FIG. 6B) is equal to or higher than the height H2 of the outer appearance portion 33, the presser portion 34 faces the outer appearance portion 33 around the bent portion 35. When it deform | transforms so that it may incline, a part of upper surface 342 may become higher than the upper surface 331 of the external appearance part 33, and there exists a possibility that it may be visible from the front. However, since the height of the presser part 34 is lower than the height of the external part 33 here, when the molding 30 is viewed from the front, only the external part 33 is visible and the presser part 34 is not visible.

  Here, as shown in FIG. 8A, when one inner wall 261 of the groove portion 26 is raised, the upper surface 342 side of the presser portion 34 of the end straight portion 321 of the molding 30 is pressed against the inner wall 261 (FIG. 8A). ) (See middle arrow A1), and in this state, the end straight portion 321 is pushed into the groove 26 (see arrow A2 in FIG. 8A). As a result, as shown in FIG. 8B, the holding portion 34 can be deformed and fixed to the groove portion 26 of the molding 30.

  FIG. 9A shows a case where the height of the inner wall of the groove portion 26 is the same, and the end straight portion 321 is inserted into the groove portion 26 provided on the back surface of the grill decoration plate 27. The width H4 of the groove 26 is slightly smaller than the width H3 of the molding 30. For this reason, when the end straight portion 321 of the molding 30 is pushed into the groove portion 26 from above, the chamfered portion 341 of the presser portion 34 comes into contact with the upper end portion of the groove portion 26.

  When the molding 30 is further pushed in, as shown in FIG. 9B, the chamfered portion 341 is deformed and the presser portion 34 is inclined, and the presser portion 34 comes into contact with the rear surface 332 of the outer appearance portion 33 (FIG. 9B). ) See middle arrow C). It is fixed to the groove 26 by the elastic force of the molding 30. Thus, since the end straight part 321 is securely fixed to the groove part 26, the bent part 32 can be fixed to the rib 25. Accordingly, the intermediate straight portion 31 is attached to the grill decoration plate 27 along the rib 25.

Next, the effect of the air conditioner 10 of this invention is demonstrated. The grill decoration plate 27 has ribs 25. Further, the molding 30 is made of an extrusion-molded product, and in a cross-sectional view, the exterior portion 33, a presser portion 34 provided in the vertical direction so as to face the exterior portion 33 at a predetermined interval, and the exterior portion 33. And a bent portion 35 that connects one end sides of the presser portion 34 to each other. The molding 30 is attached to the rib 25. At this time, the pressing portion 34 is deformed inward in the bending portion 32 of the molding 30 that bends in accordance with the shape of the front cover 24. The end portion 25 a of the rib 25 in the vicinity of the bending portion 32 of the molding 30 can be fixed by being sandwiched between the appearance portion 33 and the pressing portion 34. For this reason, since it is not necessary to provide a nail | claw in the front cover 24, manufacturing cost can be held down. In addition, the molding 30 can be easily attached to the rib 25 of the grill decoration plate 27 and can be prevented from easily falling off.


Furthermore, in the air conditioner 10 of the present invention, since the presser portion 34 is lower than the outer appearance portion 33, when the presser portion 34 is deformed inward, the presser portion 34 jumps from the outer appearance portion 33 when viewed from the front side. I can't see it. For this reason, the designability can be improved.

  The air conditioner 10 of the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made. For example, in the above-described embodiment, the rib 25 provided on the grill decorative plate 27 is provided with a shape protruding downward and inserted into the recess 36 of the molding 30 from above (FIG. 7A and FIG. 7). (See (B)). However, the ribs 25 may be sandwiched from above by providing, for example, two ribs 25 that protrude downward.
