Title:
AIR BLOWING TYPE DISCOLORATION DEVICE
Document Type and Number:
Japanese Patent JP3643968
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To extend an air circulation passage inside a cold source chamber, to enlarge the contact amount of cold blocks and circulated air and to improve cooling performance by providing a partition wall inside the cold source chamber and bending the air circulation passage inside the cold source chamber.
SOLUTION: For this air blowing type discoloration device 1 for blowing cold air to a thermal discoloration object and thermally discoloring the thermal discoloration object, a suction port 21 and an ejection port 22 are provided on the outer surface of a casing 2, the cold source chamber 3 housing the plural cold blocks 31 and an air blowing means 51 for circulating external air taken in from the suction port 21 inside the cold source chamber 3, turning it to the cold air and ejecting it from the ejection port 22 are provided inside the casing 2, and by providing the partition wall 4 inside the cold source chamber 3, the air circulation passage inside the cold source chamber 3 is bent. Thus, the air circulation passage inside the cold source chamber is extended, the contact amount of the cold blocks and the circulated air is increased and the cooling performance is improved further.
