する必要があった。Conventionally, this type of refrigerator has a cooler 5 at the rear of the freezer compartment, a defrosting heater 6 below the cooler, and a reflector 11 installed before and after the cooler to remove the frost by radiant heat from the defrosting heater 6. A cold air circulation passage 8 that guides cold air from a cold air forced circulation type refrigerator-freezer that performs frosting from the freezing compartment 3 to the refrigerator compartment 4 has a square hole 14 opened in an inner box 9 on the rear wall of the cooling compartment, and a square hole 14 in the inner box 9 on the rear wall of the cooling compartment. A duct 15 with a U-shaped cross section, which is a separate part, is attached to the back side and forms a cold air circulation passage 8 together with the inner box wall. In order to prevent leakage into the interior of the duct, it was necessary to apply sealing tape or the like to the joint between the duct and the inner box.

この考案は上記欠点を除去することを目的とするもので
ある。This invention aims to eliminate the above-mentioned drawbacks.

以下図示実施例についてこの考案を詳細に説明すると、
１は冷蔵庫本体で、この本体体を仕切断熱壁２により冷
凍室３および冷蔵室４の上下２室に区画形成している。This invention will be explained in detail with reference to the illustrated embodiments below.
Reference numeral 1 denotes a refrigerator body, which is divided into two upper and lower chambers, a freezing chamber 3 and a refrigerating chamber 4, by a partitioning thermal wall 2.

に凹部１０を一体形成して構成している。5 is a cooler disposed close to the rear wall of this freezer; 6
is a defrosting heater installed at the bottom of this cooler, 7 is an insulating partition plate installed in front of the cooler 5 and partitions the gold mine of the freezer compartment 3, and 8 is a fan installed at the top of the cooler 5. A recess 10 is integrally formed on the back surface of the inner box 9, and is a cold air circulation passageway that guides a portion of the cold air blown into the freezer compartment 3 to the refrigerator compartment 4 by means of a recess (not shown).

１１はアルミ板等からなる反射板で、上記除霜用ヒータ

とにより上記冷気循環通路８を形成している。Reference numeral 11 denotes a reflector plate made of an aluminum plate or the like, which is fixed with an adhesive or the like before and after the cooler 5 in order to promote the radiant heat of the defrosting heater 6 and to prevent heating of surrounding members. The cold air circulation passage 8 is formed by pasting the plate 10 so as to close the front opening surface of the plate 10 .

なお１２は内箱９と外箱１３の空間に注入発泡してなる
発泡断熱材である。Note that 12 is a foamed heat insulating material that is injected and foamed into the space between the inner box 9 and the outer box 13.

この考案による冷気循環通路８は以上述べたように構成
しているから、従来のように別部品からなるダクトを使
用する必要がないばかりでなく、内箱後壁の裏側にダク
トをテープ等により取付ける作業がなくなる。Since the cold air circulation passage 8 according to this invention is constructed as described above, not only is there no need to use a duct made of separate parts as in the past, but the duct is attached to the back side of the rear wall of the inner box using tape or the like. No more installation work.

また発泡性断熱材の注入発泡時の洩れ防止用のシーリン
グテープの取付は作業の必要もなくなるものである。Furthermore, there is no need to attach a sealing tape to prevent leakage when the foaming heat insulating material is injected and foamed.

以上述べたようにこの考案は、内箱背面に凹部を一体に
形成するとともに、その開口部分に反射板で塞ぐように
貼ることにより冷気循環通路を形成するようにしたから
従来のものと比較して、部品点数および作業性の点から
大巾に改良できものである。As mentioned above, this idea is better than the conventional one because a recess is integrally formed on the back of the inner box, and a cold air circulation passage is formed by pasting a reflective plate to cover the opening. Therefore, it can be greatly improved in terms of the number of parts and workability.
