泡充填している。This refrigerator is equipped with a freezer compartment 2, a refrigerator compartment 3, a vegetable compartment 4, etc. The insulated box side that forms these consists of an outer box 5 and an inner box 6. is fixed,
A foamable heat insulating material 7 is injected and foamed between the outer frost 5 and the inner box 6.
第２図は同放熱バイブＩの形状および取り付け方を示す
要部斜視図である。FIG. 2 is a perspective view of the main parts showing the shape and attachment method of the heat dissipation vibrator I.
放熱パイブ１は外箱５の限られた領域内に密着させるた
め、図示の様な形状に折り曲げ形成し、材質は磁性材料
である鉄パイプを用いている。The heat dissipation pipe 1 is bent into the shape shown in the figure in order to fit closely within a limited area of the outer box 5, and is made of an iron pipe made of a magnetic material.
外箱５の内壁には第３図に示すように、放熱バイブ１の
形状に合わせたＵ字溝８を形成している。As shown in FIG. 3, a U-shaped groove 8 is formed in the inner wall of the outer box 5 to match the shape of the heat dissipation vibrator 1.
このＵ字溝８は放熱バイブ１との接触面積がより大きく
なるように考慮されている。This U-shaped groove 8 is designed to have a larger contact area with the heat dissipation vibrator 1.
放熱パイプ１はこのＵ字溝８に添わせて載置し、要部を
アルミ箔テープ９等により仮止めしている。The heat dissipation pipe 1 is placed along this U-shaped groove 8, and its main parts are temporarily fixed with aluminum foil tape 9 or the like.
外箱５と内箱６とは前記放熱バイブ１の仮止め作業終了
後に組み合わされ、第４図に示す発泡性断熱材７を注入
するための治具１０にセットされる。The outer box 5 and the inner box 6 are assembled after the temporary fixing work of the heat dissipating vibrator 1 is completed, and set in a jig 10 for injecting the foamable heat insulating material 7 shown in FIG. 4.
治具１０は外箱５を包む治具１０ａと内箱６を押さえる

箱６との間に注入される発泡性断熱材７が発泡充填して
固化するまで保持される。The jig 10 is composed of a jig 10a that wraps the outer box 5 and a jig 10b that presses the inner box 6. An electromagnet 11 is installed in the jig 10a to attract the heat dissipation pipe 1 to the inner wall of the outer box 5. The electromagnet 11 is started to operate before the injection of the foamed heat insulating material 7 is started, and the heat dissipating pipe 1 temporarily fixed to the inner wall of the outer box 5 is sucked into the U-shaped groove 8, and the electromagnet 11 is connected to the outer box 5. The foamable heat insulating material 7 injected between the inner box 6 and the inner box 6 is foam-filled and held until solidified.
放熱パイプ１はこのように充填された発泡性断熱材７に
より外箱５の内壁に押し付けられて密着固定される。The heat dissipation pipe 1 is pressed against the inner wall of the outer box 5 by the foamed heat insulating material 7 filled in this way and is tightly fixed.
したがって、従来のように多量のアルミ箔テーブ９を使
用する必要性もない。Therefore, there is no need to use a large amount of aluminum foil tape 9 as in the conventional case.
