Title: Mount structure of foaming port/spacer for refrigerator insulating material
Inventor: SHIMIZU TAKAO
IPC: F25D23/08
Filed: 1991-07-05
Abstract: PURPOSE:To definitely fix a spacer with an interior member by inserting a notched portion of a remaining projection into a notch whose width is equivalent to a spacer installed to a corner-projection which joins two interior members and fitting a part of the space into the notched portion of the interior member. CONSTITUTION:A remaining portion of a notch 7 of an interior member is inserted into a cut 16 installed to a corner inside a spacer 8. As a result, the cut depth and the height of the remaining portion of the notch 7 are equalized so that projections 11 and 12 of the spacer 8 or a plane section 10 may come into contact with a horizontal board 3. Since the width of the spacer 8 is identical to that of the notch 7, it is possible to fit the spacer into the notch 7. As a result, the spacer 8 is turned into a condition that it is clamped with the interior member. It is, therefore, possible to resist against the vertical force of an air foaming passage 9 and the horizontal force of the shaft of the passage 9.

The Peltier element 139 is controlled to raise the temperature and the temperature of the optical filter 138 is raised. Filter characteristics of the optical filter 138 is shifted to the high wavelength side through temperature rise and gain difference between wavelengths can be compensated.
