Abstract: PROBLEM TO BE SOLVED: To air-sterilize the interior or sterilize the surface of a foodstuff stored on the wall surface and in the interior by diffusing a sublimable or volatile anti-bacteria/anti-mold agent into the interior with a fan. SOLUTION: A supply opening 31, which supplies a part of air cooled with a cooler 25, to a freezer compartment 17 and a freezer compartment return opening 32, which returns the air from the freezer compartment 17 to a cooler compartment 24, are provided on the rear surface wall 30 of the freezer compartment 17. An air supply duct 21, which sends cooled air to a storage compartment 16 is provided on the upper part of the cooler compartment 24. An anti- bacteria and deodorizing circulating air supply duct 24 is provided vertically at the center of the rear surface wall of the storage compartment 16, thereby forming a cooled air suction opening 35 in the lower part and a cooled air discharge opening 36 in the upper part. A sublimable or volatile anti-bacteria and anti-mold agent 37 is provided in such a bactericidal deodorizing circulating air supply duct 34 as described above. The anti-bacteria/anti-mold agent 37 is diffused into the interior, centering on the cold storage compartment 16 by driving a deodorizing and anti-bacteria fan 39. It is, therefore, possible to sterilize the surface of foodstuff stored with higher efficiency.

Abstract: PROBLEM TO BE SOLVED: To prevent quality of stored foods stored in a temperature range of 0 deg.C to -5 deg.C such as frozen fresh meat and marine fish or the like, in particular, from being deteriorated. SOLUTION: Either a part of or all of a low temperature chamber 11 is applied as an electrical field processing chamber 12. This processing chamber 12 is provided with a high voltage electrode 24, a flat-plate opposing electrode 25 arranged in opposition to the high voltage electrode 24 and a high voltage power supply 26. An electrical field processing is carried out during a period ranging from storing foods to a time until an inner side of the electrical field processing chamber 12 is cooled down to 0 deg.C or less under an operation of a food storing sensor means 28 and an operation of a temperature sensing means 31, thereby a refrigerator in which no freezing occurs in a temperature range of 0 deg.C to -5 deg.C can be attained.

Abstract: PURPOSE: To maintain the high humidity of a vegetable room and a meat and fish storing room, suppress the fertility of putrefying bacteria (low temperature bacteria) by the sterilizing action of the mixed gas of carbon dioxide and ozone and extend a period in which food can be preserved by naturally moving steam and carbon dioxide exhausted owing to the respiration of vegetables and fruits stored in the vegetable room to the meat and fish storing from the vegetable room according to the stored state of them. CONSTITUTION: A meat and fish storing room 21 and a vegetable room 22 are arranged so as to be adjacent to each other. The two storing rooms 21 and 22 are partitioned by a partition plate 29 having a gas permeable film 29b capable of permeating steam and carbon dioxide and an ozone generator 34 is provided in a ventilation passage communicating with the meat and fish storing room 21 from a cooler 13.

Abstract: PURPOSE:To adsorb and remove ethylene gas positively and permit the long period preservation of vegetables and fruits by a method wherein a lid body, to which a sheet type fibrous active carbon, having penetrating holes and added with bromine, is attached so as not to spoil the moisture permeability thereof, is provided on an opening at the upper surface of a vessel so as to be brought into close contact. CONSTITUTION:Moisture, discharged by the breathing effect of vegetables and fruits 29, permeates into a refrigerating chamber 16 having a comparatively low humidity through a permeable film 24 gradually and, therefore, the inside of a vegetable chamber 18 will never become too much humid condition and is maintained in the humidity of the degree of 80-95% RH suitable for the preservation of general vegetables and fruits. On the other hand, much amount of ethylene gas is discharged by the breathing effect of the vegetables and fruits 29, especially the fruits such as apples and the like, however, the gas is adsorbed and removed by the effect of bromine added to fibrous active carbon 26 whereby the trouble of soft and weak vegetables such as spinach, lettuce and the like due to the ethylene gas may be prevented. Further, uncomfortable rotten smell or mixed smell in the vegetable chamber 18 may be removed by the deodorizing power of the fibrous active carbon 26.

Abstract: PURPOSE:To retain the deodorizing ability for a long period of time by deodoring the refrigerator by means of fibrous active charcoal attached to the outer surface of a defrosting heater in the cooling compartment so that the active charcoal may be regenerated by the activation of the heater at the time of defrosting. CONSTITUTION:The cold air in the refrigerator 3 is drawn into a suction passage 10 by means of a fan 6, and its odor is effectively removed by being adsorbed by the fibrous active charcoal 11b in a deodorizing device 11 which is disposed in the cooling compartment 8. The defrosting heater 11a is automatically activated to perform the defrosting for about 30 minutes when the cooling unit 5 is covered with a certain amount of frost, and, at the same time, the odorous substances adsorbed by the fibrous active charcoal 11b are dissolved and the humidity is dried out.

Abstract: PURPOSE:To retain the ability to deodorize in the refrigerator compartment over a long period of time by providing a heat generator in the cold air suction passage from the refrigerator compartment and fibrous active charcoal around said heat generator. CONSTITUTION:The cold air containing odor in the refrigerator compartment 3 is sucked into a suction passage 10 by a fan 6, and the odor is efficiently absorbed by the fibrous active charcoal 11b in a deodorizing device 11 disposed in the inlet side opening 10a of the suction passage 10. If the user senses the odor in the compartment due to the degradation of the deodorizing ability, he or she turns on the electricity on a heating element 11 to heat the fibrous active charcoal 11b so as to decompose absorbed odorants and dry the moisture. The fibrous active charcoal 11b can be periodically heated for reactivation.
