  As shown in FIGS. 2, 4, and 5, the panel unit 3 that covers the opening 5 is rotatably provided on the main body case 1 by a rotation support unit that rotatably supports the left and right directions. The rotation support portions are provided on the upper and lower portions of the panel portion 3.

  The panel portion 3 has a vertically long rectangular plate-shaped plate portion 3A and a plate-shaped frame portion 3B extending inward of the main body case 1 from an edge of the plate portion 3A. The frame portion 3B includes an upper frame portion 20, a lower frame portion 21, one side frame portion 22, and another side frame portion 23. The plate 3A and the frame 3B are integrally formed of a resin material.

  The upper frame portion 20 has an elongated flat plate shape protruding inward of the main body case 1 from the upper end of the plate portion 3A, and has upper and lower surfaces.

  The lower frame portion 21 has an elongated flat plate shape projecting inward from the main body case 1 from a lower end of the plate portion 3A, and has upper and lower surfaces.

  The one side frame portion 22 has an elongated flat plate shape protruding inward of the main body case 1 from an end on one side (right side in FIG. 5) in the left-right direction on the surface of the plate portion 3A. In addition, one side in the left-right direction of the surface is one side in a horizontal direction parallel to the surface.

  The other side frame portion 23 has an elongated flat plate shape protruding inward from the main body case 1 from an end on the other side (left side in FIG. 5) in the left-right direction on the surface of the plate portion 3A.

  The panel portion 3 has a substantially shallow dish shape by the plate portion 3A and the frame portion 3B. The dimensions of the lower frame portion 21, the one side frame portion 22, and the other side frame portion 23 in the direction in which the plate portion 3A protrudes inward from the main body case 1 are the same. The dimensions of the lower frame portion 21, the one side frame portion 22, and the other side frame portion 23 in the direction protruding inward from the plate portion 3 </ b> A from the plate portion 3 </ b> A in the upper frame portion 20 are different from the plate portion 3 </ b> A. Is smaller than the dimension in the direction protruding inward. Thereby, the panel unit 3 is configured such that the vertical direction of the panel unit 3 is more flexible than the horizontal direction of the surface of the panel unit 3.

  The rotation support portion provided on the panel portion 3 includes a lower shaft portion 24, a lower bearing portion 25, an upper shaft portion 18, and an upper bearing portion 19. FIG. 6 is an enlarged view of the rotation support section at the top of the main body.

  The lower shaft portion 24 extends downward from the lower end on one side (the left side in FIG. 5) of the left and right edges on the surface of the panel portion 3. The lower shaft portion 24 is provided below the panel portion 3 and extends downward from the lower end of one of the left and right sides (the left side in FIG. 5) of the lower frame portion 21 of the panel portion 3 on the surface of the plate portion 3A of the panel portion 3. These are cylindrical projections. The lower bearing portion 25 is a cylindrical hole provided on the edge of the opening 5 of the main body case, into which the lower shaft portion is rotatably fitted.

The upper shaft portion 18 extends downward from the upper end on one side (the left side in FIG. 5) of the left and right edges on the surface of the panel portion. The upper shaft portion 18 is provided on the upper portion of the panel portion 3 and extends upward from the upper end of one of the left and right sides (the left side in FIG. 4) of the upper frame portion 20 of the panel portion 3 on the plate portion 3A surface of the panel portion 3. These are columnar projections. The upper shaft portion 18 includes an inclined surface portion 26 whose upper end is inclined downward from the outer surface to the inner surface of the panel portion 3. (See Fig. 6)
The upper bearing portion 19 is a cylindrical hole provided on the edge of the opening 5 of the main body case 1 and into which the upper shaft portion 18 is rotatably fitted.

  In the above configuration, when the panel portion 3 is opened, a part of the outer surface of the panel portion 3 and the contact portion 28 provided on the main body case 1 come into contact with each other. 26, the upper shaft portion 18 is separated from the upper bearing portion 19. More specifically, when a force is further applied in the opening direction of the panel portion 3 from the state where the panel portion 3 and the contact portion 28 are in contact with each other, the contact portion 28 that contacts the panel portion 3 becomes the upper and lower portions of the contact portion 28. The center of the contact portion 28 is separated from the panel portion 3. This is because the panel portion 3 bends in the vertical direction. As described above, since the vertical direction of the panel portion 3 is bent, the length of the bent portion of the panel portion 3 is longer than the case where a part of the panel portion 3 is bent, and the durability of the bent portion is improved. improves. The term “bending in the vertical direction of the panel portion 3” means that the panel portion 3 is deformed and the dimension of the panel portion 3 in the vertical direction is reduced.

  Further, the panel unit 3 is configured such that the vertical direction of the panel unit 3 is more flexible than the horizontal direction of the surface of the panel unit 3. Since the panel section 3 has a vertically long rectangular shape, the vertical dimension is larger than the horizontal dimension, so that the vertical direction of the panel section 3 is more easily bent than the horizontal direction of the panel section 3. Specifically, the vertical dimension of the one frame portion 22 is larger than the horizontal dimension of the upper frame portion 20, and the vertical dimension of the one frame portion 22 is larger than the vertical size of the tank portion 15. Since it is larger than the dimensions, the vertical direction of the panel unit 3 is more likely to bend than the horizontal direction of the panel unit 3.

  In addition, a reinforcing portion 27 that suppresses bending of the upper portion of the panel portion 3 is disposed at the center of the upper portion of the panel portion 3. The reinforcing portion 27 has a configuration in which the upper center of the panel portion 3 is recessed inward of the main body case 1. The upper end of the reinforcing portion is open. The size of the reinforcing portion 27 recessed inward from the panel portion of the main body case 1 is larger than the size of the upper frame portion 20 protruding inward of the main body case 1 from the panel portion 3. Thereby, the left-right direction on the surface of the panel unit 3 is less likely to bend than the up-down direction on the panel unit.

  Above the reinforcing portion 27, a first handle 30 provided in the main body case 1 is arranged. The first handle portion 30 has a shape in which a first side surface 1 </ b> A, which is a side surface on one side (the right side in FIG. 1) of the main body case 1 swells outward. The user can put a finger of the hand into the reinforcing portion 27 and hook the finger under the first handle portion 30. On a second side surface (not shown) on the other side (the left side in FIG. 2) of the main body case 1, a second handle portion (not shown) having a concave shape inward is arranged. The user can put a finger of the hand into the second handle (not shown) and hook the finger on the upper part of the second handle (not shown). Thus, the user can hook the finger on the first handle 30 and the second handle (not shown), lift the main body case 1, and move the main body case 1.

  Furthermore, the horizontal dimension of the reinforcing portion 27 is larger than the dimension from the reinforcing portion 27 to one horizontal end of the panel portion 3 and from the reinforcing portion 27 to the other horizontal end of the panel portion in the horizontal direction. Larger than the size of. Thereby, the horizontal dimension of the upper frame portion 20 is reduced, so that the upper portion of the panel portion 3 can be further suppressed from bending in the left-right direction on the surface of the panel portion 3.

  Further, the contact portion 28 is a vertically long rectangular surface. Specifically, one side (left side in FIG. 1) of the panel portion 3 adjacent to the first side surface in the horizontal direction has a third side surface (the back surface in the main body case in FIG. 1) of the main body case. I have. The contact portion 28 is disposed at an end of the third side surface on the panel portion 3 side. Thereby, the area of the panel portion 3 that comes into contact with the contact portion 28 is increased, and the concentration of the load on the panel portion 3 at one location can be reduced.

  The contact portion 28 corresponds to a contact area 29 in the panel section 3. The distance between the contact area 29 and the upper shaft portion disposed on one side (the right side in FIG. 7) of the panel section 3 is the distance between the contact area 29 and the other end (the left side in FIG. 7) of the panel section 3. Less than. As a result, when the contact portion 28 hits the contact area 29 of the panel portion 3 and a force is applied to the other side (left side in FIG. 7) of the panel portion 3 in a direction in which the panel portion 3 opens, the principle of leverage increases It is considered that the shaft portion 18 is likely to come off.

  INDUSTRIAL APPLICABILITY The present invention is suitable as an air conditioner having an opening for maintenance on a side surface of a main body case, and having an opening and closing panel portion in the opening.
