Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
An apparatus for preserving perishable goods, comprising: a refrigerating chamber for storing perishable goods provided with a door on one side; a perforated plate separating the inside of said refrigerating chamber into upper and lower chambers; a cold-air blow out hole of a cooling unit having a suction port which is disposed in said upper chamber and through which cold air blows therethrough; a goods preserving compartment formed in said lower chamber separated by said perforated plate; a duct means communicating said suction port side of said cooling unit with the lower portion of said preserving compartment; a sterilizing means disposed in said duct means; a humidifier positioned to humidify the cold air blowing from said cooling unit; a slit formed between said door and said perforated plate and extending along the inner side of said door, whereby the cold-air blowing from said blow out hole of the cooling unit passes through small openings in said perforated plate and enters into said preserving compartment under a higher pressure than the pressure in said preserving compartment, and at the same time a portion of the cold air passing through said slit into said preserving compartment forms an air curtain inside said door.
Claim 2
Independent Claim

An apparatus for preserving perishable goods, comprising: a refrigerating chamber for storing perishable goods provided with a door on one side; a perforated plate separating the inside of said refrigerating chamber into upper and lower chambers; a cold-air blow out hole of a cooling unit having a suction port which is disposed in said upper chamber and through which cold air blows therethrough; a goods preserving compartment formed in said lower chamber separated by said perforated plate; a duct means communicating said suction port side of said cooling unit with the lower portion of said preserving compartment; a sterilizing means disposed in said duct means; a humidifier positioned to humidify the cold air blowing from said cooling unit; a slit formed between said door and said perforated plate and extending along the inner side of said door, whereby the cold-air blowing from said blow out hole of the cooling unit passes through small openings in said perforated plate and enters into said preserving compartment under a higher pressure than the pressure in said preserving compartment, and at the same time a portion of the cold air passing through said slit into said preserving compartment forms an air curtain inside said door.
Claim 3
Dependent Claim
24 words
The apparatus as set forth in claim 1, wherein the flow rate of said cold air flowing from said blow out hole is adjustable.
Claim 4
Dependent Claim
34 words
The apparatus as set forth in claim 2, wherein the flow rate of said cold air after passing through the openings in the perforated plate is in the range of 50 to 90 cm/sec.
Claim 5
Dependent Claim
51 words
The apparatus as set forth in claim 1, further comprising a filter having an adsorptive material therein which is positioned in the circulation passage of said cold air blowing from said blow out hole, said adsorptive material being able to adsorb the volatile nitrogen base triethylamine released from said perishable goods.
Claim 6
Dependent Claim
24 words
The apparatus as set forth in claim 4, wherein the flow rate of said cold air blowing from said blow out hole is adjustable.
Claim 7
Dependent Claim
34 words
The apparatus as set forth in claim 5, wherein the flow rate of said cold air after passing through the opening in the perforated plate is in the range of 50 to 90 cm/sec.
Claim 8
Dependent Claim
19 words
The apparatus as set forth in claim 4, wherein said adsorptive material has the ability to adsorb ethyl alchol.
Claim 9
Dependent Claim
27 words
The apparatus as set forth in claim 7, wherein said sterilizer is a device which supplys an ethyl alcohol solution of a concentration of at least 30%.
Claim 10
Dependent Claim
43 words
The apparatus as set forth in claim 8, wherein said adsorptive material is provided in the range of 190 to 580 g per 1 m 3 of said refrigerating compartment and is particulate material having a grain size of at least 50 mesh.
