Abstract
Abstract Here is disclosed a compact refrigerator to cool containers filled with soft drink or the like, particularly such refrigerator miniaturized and flattened so as to be installed near by a crample seat of minicar. This compact refrigerator comprises a container supporting member formed with a plurality of wells arranged side by side in a line to receive the containers, a heat exchanging mechanism functioning under a heat absorption effect of a thermoelectric cooling element, and a casing provided with a pivotal cover and said heat exchanging mechanism, thus presenting a flattened box-like configuration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
An electronic compact refrigerator comprising: a flat box-like casing; a pivotal cover provided on the top of said casing a thermally conductive container supporting member provided within said casing, said container supporting member defining at least one well for receiving a container having an exterior side surface and an exterior bottom surface, said well of said container supporting member including a side wall and a bottom wall which come into close proximity to said exterior side surface and bottom surface , respectively, of the container and which cover substantially all of said exterior side surface and bottom surface of the container to thereby facilitate heat transfer between the container and said supporting member; and a heat exchanging means including a thermoelectric cooling element provided within said casing and thermally coupled to said container supporting member for cooling said container supporting member under a heat absorption effect of said thermoelectric cooling element.
Claim 2
Dependent Claim
151 words
An electronic compact refrigerator comprising: a flat box-like casing; a pivotal cover provided on the top of said casing a thermally conductive container supporting member provided within said casing, said container supporting member defining at least one well for receiving a container having an exterior side surface and an exterior bottom surface, said well of said container supporting member including a side wall and a bottom wall which come into close proximity to said exterior side surface and bottom surface , respectively, of the container and which cover substantially all of said exterior side surface and bottom surface of the container to thereby facilitate heat transfer between the container and said supporting member; and a heat exchanging means including a thermoelectric cooling element provided within said casing and thermally coupled to said container supporting member for cooling said container supporting member under a heat absorption effect of said thermoelectric cooling element.
Claim 3
Dependent Claim
100 words
An electronic compact refrigerator as recited in claim 1 further comprising an adapter to be received in said well of said supporting member, said adapter defining therein a second well for receiving a container having an exterior side surface and an exterior bottom surface wherein said second well includes a side wall and a bottom wall which come into close proximity to said exterior side surface and bottom surface, respectively, of the container and which cover substantially all of said exterior side surface and bottom surface of the container thereby effecting maximum heat transfer between the container and said adapter.
Claim 4
Dependent Claim
31 words
An electronic compact refrigerator as recited in claim 1, wherein said casing is entirely or partially formed from transparent material and said container supporting member is also formed from transparent material.
Claim 5
Dependent Claim
22 words
An electronic compact refrigerator as recited in claim 1, wherein only the pivotal cover of the casing is formed from transparent material.
Claim 6
Dependent Claim
48 words
An electronic compact refrigerator as recited in claim 1, wherein said casing is entirely or partially formed from transparent material, said container supporting member is formed from opaque material, and the container supporting member is provided through its front wall with slit-like windows extending to the respective wells.
Claim 7
Dependent Claim
79 words
An electronic compact refrigerator as recited in claim 1, wherein an automatic vending mechannism having a coin slot is incorporated into said casing and this automatic vending mechanism is provided with a locking device adapted normally lock each of the containers stored in the refrigerator but to unlock the container in response to a coin thrown into the automatic vending mechansim through said coin slot so that one of the containers may be freely taken out from the refrigerator.
Claim 8
Dependent Claim
23 words
An electronic compact refrigerator as recited in claim 1 wherein said container supporting member includes a plurality of wells for receiving containers therein.
Claim 9
Dependent Claim
22 words
An electronic compact refrigerator as recited in claim 7, wherein said plurality of wells of said container supporting member comprise different depths.
Claim 10
Dependent Claim
23 words
An electronic compact refrigerator as recited in claim 7, wherein said plurality of wells of said container supporting member comprise different inner diameters.
