Description

  The present invention relates to an internal unit of an integrated air conditioner.

  As shown in FIG. 6, the conventional integrated air conditioner has an outdoor heat exchanger 103 in which an internal unit 101 is erected on a base 102 so that the base 102 is bent into a U shape. A partition plate 107 is provided for partitioning into an outdoor heat exchange chamber 104 and an indoor heat exchange chamber 106 having an indoor heat exchanger 105. The partition plate 107 is erected on the base 102 of the outdoor heat exchange chamber to blow the wind of the propeller fan 108. It is known that an air guider 110 including a fan ring 109 for guiding is provided and a connecting bar 111 is welded between the partition plate 107 and the air guider 110 in a bridging manner (for example, Patent Document 1).

  The partition plate 107 that separates the outdoor heat exchange chamber 104 and the indoor heat exchange chamber 106 and the air guider 110 that guides the wind of the propeller fan 108 are made of sheet metal. These partition plates 107 are made of sheet metal. The plurality of connecting bars 111 made of sheet metal are welded between the air guiders 110 in a bridging manner so that the internal unit 101 can be reinforced.

  However, for example, when the air guider 110 including the fan ring 109 is made of resin in order to reduce the weight of the internal unit 101 and reduce the cost, the connecting bar 111 made of sheet metal may be welded to the air guider 110 made of resin. It had the problem that it was not possible. Further, even if the sheet metal connecting bar 111 is screwed and fixed to the resin air guider 110, the rigidity of the internal unit 101 cannot be secured due to insufficient rigidity of the resin air guider 110. It was.

Screwed to each.

  The third side 15c and the fourth side 15d bridged from the upper end position of the side plates 14 and 14 to the partition plate 4 are on the inner side (closer to the fan shaft) than the side plates 112 and 112, for example, as in the background art shown in FIG. Compared to the configuration in which the connecting bar 111 is bridged and fixed from the air guider 110 to the partition plate 107, the internal unit 1 is bridged and fixed to the partition plate 4 from the position of the side plates 14 and 14 shown in FIGS. Can be more effectively reinforced.

  Moreover, a top plate 19 made of a sheet metal as shown in FIG. 2 is provided at the upper portion of the indoor heat exchanger 7 provided in the indoor heat exchange chamber 6 and the upper end portion of the bent partition plate 4. It is screwed and fixed from the upper part of the support member 15 fixed to the upper end part of the partition plate 4.

  With the configuration described above, the rigidity of the internal unit 1 housed in the outer body 2 is increased, and the number of fins is increased because the outdoor heat exchanger 9 is bent into a U shape, so that the heat transfer tubes (both The heat exchange between the refrigerant circulating in the heat transfer pipe and the air sucked from the outdoor suction port 2a by the propeller fan 10 is increased by increasing the length of the outdoor heat exchanger 9 (not shown). become able to.

  The propeller fan 10 is configured to be installed inside the U-shaped outdoor heat exchanger 9 so that the internal unit 1 can be made compact without increasing the distance between the propeller fan 10 and the outdoor heat exchanger 9. Will be able to contribute.

  The first fixing portions 16 and 16 and the second fixing portions 17 and 17 of the support member 15 are fixed screws that are screwed into the screw holes 14 a and 14 a and the screw holes 4 a and 4 a with respect to the side plates 14 and 14 and the partition plate 4. 18 and 18, the screw is firmly fixed from above and from the side.

  At that time, the support member 15 is formed in a frame shape, and the inner peripheral flange 15e and the flanges 15c1, 15d1, and 15f are integrally formed, so that the rigidity of the internal unit 1 is effectively improved by the support member 15 having increased strength. Can be reinforced.

  The support member 15 is fixed to the side plates 14 and 14 and the partition plate 4 so that the first side 15a is along the upper end of the air guider 12, so that the upper end of the air guider 12 is accurately aligned with the first side 15a. Can be positioned.

  Further, the outdoor heat exchanger 9 has a configuration in which the U-shaped open side upper end portion is closed by the first side 15 a of the support member 15, thereby increasing the strength and contributing to the configuration that reinforces the rigidity of the internal unit 1. become able to.

  As shown in FIG. 5B, the air guider 12 is provided with an engagement groove 12a with the partition plate 4 side opened at the upper end, and as shown in FIG. 5A, the bottom surface 12d of the engagement groove 12a. Thus, the first side 15a of the support member 15 is engaged so as to receive the first side 15a, thereby being accurately positioned with respect to the first side 15a.

  As shown in FIG. 5A, a screw hole 15g is provided in the first side 15a of the engaged support member 15, and the engagement groove 12a at the upper end portion of the air guider 12 corresponds to the screw hole 15g. As shown in FIG. 5B, there is provided a fixing portion 12b including a screw through hole for screwing and fixing the fixing screw 18 into the through screw hole 15g.

  The air guider 12 is made of synthetic resin and has insufficient strength by engaging the first side 15a of the support member 15 with the engagement groove 12a at the upper end and fixing the first side 15a to the engaged side. Also, it is reinforced by being fixed to the support member 15 made of sheet metal.

  In the engagement groove 12a of the air guider 12, a positioning portion 12c for positioning the first side 15a of the support member 15 at a position where the first side 15a is received and engaged by the bottom surface 12d is projected from the bottom surface 12d. The inner peripheral flange 15e of the first side 15a abuts the positioning portion 12c, and the screw hole 15g is positioned with respect to the fixing portion 12b, so that the fixing screw 18 is passed through the fixing portion 12b and screwed into the screw hole 15g. The workability of fixing with screws is improved.

  Therefore, the air guider 12 provided with the fan ring 11 is made of synthetic resin and screwed and fixed to the first side 15a, thereby reducing the weight of the internal unit 1 and reducing the cost. There is no loss of rigidity.

  As described above, according to the configuration of the present invention, the outdoor heat exchanger 9 including the side plates 14 and 14 that are bent in a U shape and fixed on the base 3 is installed in the outdoor heat exchange chamber 6. A partition plate 4 that divides the indoor side heat exchange chamber 5 and the outdoor side heat exchange chamber 6 and fixes the top plate 19 on the top is fixed on the base 3, and between the side plates 14 and 14, and between the partition plate 4 and the side plate. 14 and 14 are connected by a frame-shaped support member 15, and the air guider 12 fixed to the inner edge of the side plates 14 and 14 is the support member 15, and the air guider 12 including the fan ring 11 is made of resin to reduce the weight. The integrated air conditioner is designed to reduce costs and secure the rigidity of the internal unit 1.
