Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a heat exchange unit whose frame is covered with a front cover.

(b) Prior Art Conventionally, an example of the structure of this type of heat exchange unit has been disclosed in Japanese Utility Model Publication No. 1821/1983.

According to this content, a heat exchanger, a blower, and mounting members for electrical components are housed in a frame, and then the frame is covered with a front cover.

(c) Problems to be solved by the invention When covering the frame with a front cover in such a heat exchange unit, it is necessary to check whether the outer circumferential wall of the frame is located further outward than the inner circumferential wall of the front cover. Therefore, the assembly work has become troublesome.

The object of the present invention is to enable the front cover to be easily assembled to the frame.

(d) Means for solving the problem In order to achieve this objective, the present invention includes a mounting member built into the frame that has a mounting plate supported by a fixed piece of the frame and a wall surface having a guide piece. It is designed to provide a.

(E) Function The front cover is guided and attached to the frame by the guide piece of the mounting member attached to the frame and the wall surface.

(f) Example In the drawing, 1 is an indoor heat exchange unit of a separate air conditioner, which includes a frame 2 made of synthetic resin,
A casing is constituted by a front panel 3 (see FIG. 2) that covers this frame 2. Reference numerals 4 and 5 indicate receiving plates erected on the left and right sides of the frame 2, and a heat exchanger (not shown) is placed astride these receiving plates.
The right side 6 inside the frame 2 partitioned by this right receiving plate 5
is used as the storage area for the electrical equipment box. 7 is a cross flow fan, and 8 is a U-shaped groove in which the bearing of this fan is accommodated, and is formed below the receiving plate 5. 9 is a recess for housing the motor that drives the cross flow fan. Reference numeral 10 denotes a fixing piece that connects the lower edge 11 of the recess 9 and the lower edge 12 of the frame 2, and has a boss 13 formed thereon for attaching an electrical box (described later). 14 is a positioning piece extending inward from the lower edge of this frame.

Reference numeral 15 denotes an electrical box (mounting member) in which the electrical components of the heat exchange unit 2 are housed, and the front side thereof is open. Reference numeral 16 denotes a mounting plate of the electrical equipment box 15, which is formed at the lower part of the back plate of this box, and a terminal plate 17 is attached to the front surface of this mounting plate 16. Reference numeral 18 denotes a mounting piece for the electrical equipment box 15, which is formed on the upper surface of the electrical equipment box 15.

In such a heat exchange unit 1, when the electrical equipment box 15 is attached to the frame 2, the electrical equipment box 15 is positioned in the storage part 6 of the frame 2, and the mounting plate 16 of the electrical equipment box 15 is attached to the fixing piece 10 of the frame 2. While placing the lower part 19 of the electrical box on the boss 20 of the inner wall of the frame 2, attach the mounting piece 18 of the electrical box as shown by the two-dot chain arrow.
Then, the mounting plates 16 are positioned on the bosses 13 of the fixing piece 10, respectively. These mounting pieces 18 and mounting plate 16 are then fixed to the bosses 13 and 20 with screws.

When the electrical equipment box 15 is attached to the frame 2 in this way, as shown in FIG.
is in surface contact with the fixed piece 10 of the frame 2.
Therefore, when a screwdriver is applied to the screw of the terminal plate 17 and the screw is turned in order to connect the wiring to the terminal plate 17, the movement of the terminal plate 17 is made small to facilitate this wiring operation. Moreover, the guide piece 21 of the electrical equipment box 15 and the lower surface 22 of the frame 2 are connected, and the wall surface 23 of the electrical equipment box 15 and the outer surface 24 of the frame 2 are connected. Therefore, when the front cover 3 is placed over the frame 2, the inner wall of the front cover 3 comes into contact with the guide piece 21 and the wall surface 23 of the electrical box 15, and serves as a guide surface for the surface cover 3, and the inner wall of the front cover 3 becomes the outer surface of the frame 2. 24 and along the lower surface 22.

(g) Effects of the invention As stated above, in the present invention, the front cover is guided by the guide piece of the mounting member built into the frame and the wall surface, and is attached to the frame.
This front cover can be easily assembled to the frame.
