FIG. 3 is an explanatory diagram showing the inside of an outdoor unit using the compressor cover of the present invention. FIG. 4 is an explanatory view showing another compressor cover manufacturing process of the present invention.
FIG. 5 is an explanatory cross-sectional view of the felt material shown in FIG. 6 (1) and (2) are cross-sectional explanatory views of another compressor cover of the present invention. In FIGS. 1 to 6, portions denoted by the same reference numerals as those in FIGS.
It is a part having the same function as the part with the same reference numeral described in FIGS.

In FIG. 1, first, in FIG.
A is punched out in the width and length directions so that the margin is formed from a predetermined size. Also, the felt material 17 is manufactured by punching out a felt material 17 in which two portions 17A and 17B having the same shape as the intermediate layer which is larger by the glue margin are connected symmetrically about the folding line 22. Width W ₂ is a felt material 17A of specifically intermediate layer 16A, 17B the width W ₁ of

(B) Felt material 1 obtained in (a) above
An adhesive 19 is applied to the entire surface of the surface 7 by a roller 18. (C) After applying the adhesive 19, the intermediate layer 16A is placed at a predetermined position on the surface of the portion 17A constituting the half of the felt material 17, leaving the margin 23, and the half of the felt material 17 is removed. The other part 17B is folded in the direction of the arrow around the folding line 22 and the contact surface of both parts and the glue margin 23 are bonded to sandwich the intermediate layer 16A. The application of the adhesive 19 can be performed only once, which simplifies the operation. In addition, if the felt material 17 is folded in half before the intermediate layer 16A is placed, the intermediate layer 16A can be positioned because the folded portion 22A is provided.
