Title: Refrigerator
Inventor: SUDA NORIYUKI
IPC: F25D23/06
Filed: 1990-03-05
Abstract: PURPOSE:To improve the circulation efficiency of cooled air and enhance the efficiency of assembling work by forming a dew receiving pan integrated with an inner wall of a freezer in one piece and fitting a reinforced insulation material from the lower side of a dew receiving material, and communicating with the freezer and the opening of a refrigeration chamber. CONSTITUTION:Since a dew receiving pan 12 is continuously formed integrally with the floor surface of an inner wall of a freezer 2 in one piece, sealing work can be omitted. Each passage communicating with a reinforced insulation material 13 and a connection part of each entrance and exit communicating with a freezer 2 and a refrigeration chamber 3 is relatively small in its opening area. It can be interfaced with the reinforced insulation material 13 so that the connection part may be sealed. Therefore, sealing work is very simple so that a refrigerator main body may be simply formed. Furthermore, a cooled air reflux outlet 18, which is an exit of a cooled air reflux passage 14 on a cooler side, which refluxes the cooled air circulating to the refrigeration chamber 3, is formed on the back of the inner wall of the freezer 2 while the cooled air reflux passage 14 is constructionally communicating with the wall on the back of a refrigerator main body. This construction makes it possible to maintain a sufficient area for the cooled air reflux passage and hence circulate cooled air to a satisfactory extent without any resistance.
