Abstract
Abstract Disclosed is a refrigerator comprising a freezing compartment and a refrigerating compartment in which the freezing compartment can be used as a refrigerating compartment. The two compartments are in close proximity. Means are provided in a cooling-air passage to supply cooling air generated from an evaporator into both of the compartments or selectively only into one compartment.

Claim 1
Independent Claim
314 words
A refrigerator including a temperature-controlling thermostat and an evaporator comprising: (a) a freezing compartment having said temperature-controlling thermostat therein and being able to be used as a refrigerating compartment, (b) a refrigerating compartment positioned below said freezing compartment, (c) cooling-air incoming passages connected to each of said compartments at inlets for supplying cooling air from said evaporator into each of said compartments, (d) a cooling-air flow regulator, located at the refrigerating compartment inlet of the cooling-air incoming passage, said regulator adjustably to be open for permitting the flow of cooling air and adjustable to be completely closed for preventing the flow of cooling air into said refrigerating compartment, said regulator including: (i) a regulator body, (ii) a flexible actuating member which is mounted on said regulator body, (iii) a support lever rotatably mounted by pivot pin on said regulator body in front of said actuating member and having a curved portion, (iv) a shutter which is attached to and supported by a top end of said support lever, said shutter disposed rotatably in said refrigerating compartment and operated by said support lever to close or open said refrigerating compartment inlet for increasing or decreasing the flow of cooling air through the cooling-air incoming passage, (v) a control member which is rotatably connected to said regulator body, said member having indications of cooling extent, an indication of complete closing position for said shutter on the front face thereof, having a cam device being formed by a top plane in the opposite side of said indication of complete closing position and a sloped surface annularly extended from one side of said top plane to the other side of said top plane, so that said control member operates to urge rearwardly the curved portion of said support lever by said cam device and to fix said support lever at the position for complete closing of said shutter.
