摘要： PURPOSE:To prevent the piping from having thermal effect on the refrigerator chamber, by placing a pipe, which is conventionally laid near a partition, below the bottom of an inner box so that a hot pipe downstream the lower end of the partition solidly formed in the inner box can contact with it and leading it outside the insulating box. CONSTITUTION:A pipe 17a, which is conventionally laid near a partition, is placed below the bottom 8a of an inner box 8 so that another pipe 17 downstream the lower end of the partition solidly formed in the inner box, and the pipe 17 is lead to the rear on the projection surface of the partition. The pipe 17 then goes along the bottom plate 10a of an outer box 10 and rises a little to form an arc 17b and then goes straight downward to outdoor. As a result, heat produced in the pipe does not have any effect on the refrigerating and freezing chambers 2, 3.

摘要： PURPOSE:To make it seeable at a glance the state of a chamber which is available for freezing or refrigeration, by attaching a displayer to the tip of a handling lever of a switch damper. CONSTITUTION:A switch damper 30 which selects the use of a chamber 6 for freezing or refrigeration is composed of a handling lever 31 and slide damper 30a. The lever 31 has at its tip a displayer 31b, its surface A being seeable from the front side when the displayer 31b is on the side of a partition wall 27 and its surface B being seeable from the front when the displayer is on the side of a center wall. Thus the letters A and B on both sides of the displayer 31b clearly show the position of the switch damper.

摘要： PURPOSE:To improve feasibility of refrigerator by providing a freezing chamber, refrigerating chamber and freezing-refrigerating chamber to swtich the freezing- refrigerating chamber to the freezing or refrigerating chamber if necessary to increases or decrease the volume of refrigerating and freezing chambers. CONSTITUTION:A freezing-refrigerator has a freezing chamber 5 on the upper portion, a switching chamber (freezing-refrigerating chamber) 6 and a partition wall 10 dividing the refrigerator into said both chamber. After cool air cooled by a cooler 11 is jetted into the freezing chamber 5 by a blower 15, a portion of the cool air is discharged into the switching chamber 6 through a cool air path 21 having a damper thermo 23 and the remaining cool air is returned to the cooler 11 through a pressure chamber 25 adjustably opened or closed by a switching damper 30. A portion of cool air discharged from an outlet 14 by the blower 15 is introduced into the switching chamber 6 by a partition duct plate 19 which is formed on both sides with chutes 33 for guiding dew attached to the upper surface of the partition wall 10 and partition duct plate 19 itself into a reservoir 36 privided on the bottom of inner box 6a.
