Description

[Detailed description of the invention] The present invention allows a finger to be safely and securely inserted into the vent hole of the exterior panel, which is bored facing the free space at a corner of the heat exchange unit, when the heat exchange unit is transported. By also serving as a handle, the number of parts and costs of the heat exchange unit can be reduced.

An embodiment in which the present invention is applied to an outdoor unit of a separate air conditioner will be described below with reference to the drawings.

In Fig. 1, 1 is an outdoor unit, 2 is a substantially U-shaped metal bottom plate that forms a bottom wall 3 of the unit, and left and right rising walls 4, 5. Inverted U-shaped outdoor heat exchangers 9 are mounted and fixed across the ends 7 and 8 of the walls 4 and 5, respectively, and are partitioned by partition plates 10 as shown.

In FIG. 2, reference numeral 11 indicates a fitting part 13 that is fitted into the pipe 12 of the outdoor heat exchanger 9, and a corner part 14 of the outdoor heat exchanger 9 that is bent at an acute angle with respect to the iron part. A protective cover is integrally molded with a protective portion 15 made of synthetic resin and is inserted and fixed into a corner portion 14 as shown in FIG.

Reference numeral 16 denotes a metal side exterior panel in which a large number of suction vents 18 are bored in the peripheral wall 17, which covers the outdoor heat exchanger 9 from above and connects to the ends 7, 8 of the rising walls 4, 5 and the screws 19. Side exterior panel 1 with small bending curvature when assembled and fastened
An extra space 21 is formed at the left and right upper corners of the outdoor unit 1 by the corner walls 20 of the heat exchanger 9 and the corner portions 14 of the heat exchanger 9 having a large bending curvature.

The protective portions 15 of the protective cover 11 described above are positioned inwardly facing the left and right vents 22 on the uppermost stage facing this extra space, so that the fingers inserted through the vents 22 during transportation will not touch the heat exchanger 9. This is to prevent people from getting injured by touching the fins.

Reference numeral 23 designates a metal front panel equipped with an air outlet grille 24, and the outer peripheral frame 25 of this front panel is fitted onto the front edge 27 of an intermediate body 26 that combines the bottom plate 2 and the side exterior panels 16. It covers the front part of unit 1.

Reference numeral 28 denotes a metal rear panel to which a blower 29 for forced heat exchange with the outdoor heat exchanger 9 is fixed via a fixture 30.The outer peripheral frame 31 of this rear panel is attached to the rear of the intermediate body 26 in the same manner as the above-mentioned front panel. The outdoor unit 1 is fitted onto the side edge portion 32.
It covers the rear of the.

Reference numerals 33 denote stand legs fixed to the left and right sides of the bottom plate 2, respectively, and as shown in FIG. The outdoor unit 1 is carried at a slight angle by locking the fingers of each person.

Therefore, according to the present invention, the space formed by the corner wall of the exterior panel and the heat exchanger disposed inside the corner wall can be used to store fingers inserted through the vent when transporting the heat exchange unit. In addition to using it as a space, we installed a protective cover on the inside facing the vent to prevent fingers from touching the heat exchanger, and this vent also doubles as an extremely safe handle, making it possible to create a new heat exchanger. There is no need to provide a handle on the unit, and the number of parts and costs can be reduced.
