る構造を提供するものである。[Detailed description of the invention] The present invention relates to a refrigerator in which a cooler is installed in the upper part of the refrigerator in which a plate body is formed into a box shape or the like so as to form a cold room inside, and the back wall of the cold room is In contrast to using a back plate covered by caulking or welding to the rear end opening of the cooler,
The present invention simplifies the configuration of the cold room by making this back plate a special shape so that it can also be used as the inner box that makes up the refrigerator body. The purpose of the present invention is to provide a structure that can protect the cooler from cracking due to contact with the rear end and can absorb and alleviate vibrations of the cooler.

次に本考案の実施例を図に基づき詳述する。Next, embodiments of the present invention will be described in detail based on the drawings.

１は冷蔵庫本体で真空成形等にて成形した合成樹脂の内
箱２と外箱２Ａ間に断熱材２Ｂを注入発泡せしめて構成
している。Reference numeral 1 is a refrigerator body which is constructed by injecting and foaming a heat insulating material 2B between an inner box 2 and an outer box 2A of synthetic resin formed by vacuum forming or the like.

内箱２の背壁の上部には左右及び上下壁を有し前方へ開
口した有底の小室３が内箱２内の冷蔵庫内と区画形成さ
れている。At the upper part of the back wall of the inner box 2, there is formed a small chamber 3 with a bottom, which has left and right and upper and lower walls and is open to the front and is partitioned from the inside of the refrigerator inside the inner box 2.

４はロールボンド法等にて冷媒通路を形成した板状冷却
器で、前面及び後面に開口した中空状に成形してこの中
空を冷蔵庫内よりも低温となる低温室となしている。4 is a plate-shaped cooler in which a refrigerant passage is formed by a roll bonding method, etc., and is formed into a hollow shape with openings on the front and rear surfaces, and this hollow space is used as a cold room whose temperature is lower than that inside the refrigerator.

冷却器４の後端開口縁部は小室３に受容されこの後端開
口縁部と小室３との間には弾力性の熱絶縁体５が介在し
て両者を連接している。The rear end opening edge of the cooler 4 is received in the small chamber 3, and an elastic thermal insulator 5 is interposed between the rear end opening edge and the small chamber 3 to connect them.

この熱絶縁体５は例えば軟質の塩化ビニール等で作られ
、その形状は第２図及び第３図の如く冷却器４の後端開
口縁全体に亙って嵌着されたものでもよく、また第４図
の如く後端開口縁の適所に固定して点在させてもよい。This thermal insulator 5 is made of soft vinyl chloride, for example, and its shape may be such that it is fitted over the entire rear opening edge of the cooler 4 as shown in FIGS. 2 and 3, or As shown in FIG. 4, they may be fixed and scattered at appropriate locations on the edge of the rear end opening.

本考案は上記の如く構成したことにより、前記小室３が
冷却器４で形成した低温室の後部を形威し内箱２が低温
室の背面板を兼用するため、低温室の構成が従来の冷却
器及び内箱とは別個の背面板が不要になる。With the present invention configured as described above, the small chamber 3 takes the form of the rear part of the cold room formed by the cooler 4, and the inner box 2 also serves as the back plate of the cold room, so that the structure of the cold room is different from that of the conventional one. A separate back plate from the cooler and inner box is not required.

また前記小室３の奥行きの大きさによって低温室の大き
さが冷却器の内面で作られた大きさよりも大きくなり、
従来よりも大容積の低温室を冷却器の大きさを変えるこ
となく作ることも可能となる。Also, depending on the depth of the small chamber 3, the size of the cold room becomes larger than the size created by the inner surface of the cooler,
It is also possible to create a cold room with a larger volume than before without changing the size of the cooler.

また熱絶縁体５によって内箱２が真空成形されたもので
あってもその内箱２に対する冷却器４の接触力を緩和す
るため内箱２の残留応力や薄肉化による亀裂の発生を防
止でき、更に冷却運転中の冷却器の振動も本体へ伝達さ
れるのが緩和されることになる。Furthermore, even if the inner box 2 is vacuum-formed, the thermal insulator 5 alleviates the contact force of the cooler 4 against the inner box 2, thereby preventing the occurrence of cracks due to residual stress or thinning of the inner box 2. Furthermore, the vibration of the cooler during cooling operation is also less likely to be transmitted to the main body.
