Description

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

  In the conventional integrated air conditioner, as shown in FIG. 8, the internal unit 101 is partitioned by a partition plate 102 into a front indoor heat exchange chamber A and a rear outdoor heat exchange chamber B. It is known that the rigidity of the internal unit 101 is increased by fixing a single top plate 103 to the upper part of the heat exchange chamber A and the upper part of the outdoor heat exchange chamber B (for example, Patent Document 1). ).

  However, since the top plate 103 is fixed to the internal unit 101 and the upper part of the indoor heat exchange chamber A and the upper part of the outdoor heat exchange chamber B are covered, the top plate 103 is enlarged. There was a problem that it was expensive.

  Further, in an environment where the dust is intense, the internal unit 101 is washed in order to prevent the dust from entering and the heat exchange performance from deteriorating. For cleaning, after removing the propeller fan 104, fan motor (not shown), etc. from the internal unit 101, the indoor heat exchange chamber A and the outdoor heat exchange chamber B are temporarily installed vertically. The indoor heat exchanger 107 and the outdoor heat exchanger 108 are cleaned by the cleaning device, and the dust that has entered is washed away to the outside of the machine.

  At this time, since the top plate 103 has an opening 106 only between the partition plate 102 and the air guider 105 that guides the propeller fan 104, the indoor heat exchanger 107 provided in the indoor heat exchange chamber A is provided. In order to clean the back side of the outdoor heat exchanger 108 provided in the outdoor heat exchange chamber B, the top plate 103 had to be removed from the internal unit 101.

  Therefore, when cleaning the indoor heat exchanger 107 and the outdoor heat exchanger 108, the internal unit 101 becomes insufficient in rigidity by removing the top plate 103, and therefore the indoor heat exchange chamber A and the outdoor heat exchange chamber are removed. There is a possibility that the internal unit 101 may be deformed or damaged by being temporarily installed vertically so that B is up and down.
