    Abstract: PURPOSE:To obtain heat dissipating performance of a machine room without influence of installing conditions of a refrigerator by providing a compressor, an air inlet vent hole, an air flowout vent hole at the room in a lower part of the refrigerator, providing a shielding plate at a lower part of the front surface of the refrigerator, and providing an opening at part of the plate corresponding to the forward vent hole. CONSTITUTION:When a compressor is operated, a machine room reaches a high temperature to generate a natural convection, heated air of the room starts to flow from an air flowout vent hole 4, and a flow of the air flowing to the room is simultaneously generated. The flow of the room allows the air of an ambient temperature at a front surface of a refrigerator to pass an opening 2a of a shielding plate and efficiently flows from an air inlet vent hole 3 to the room. Thus, the heated air to be discharged from the hole 4 passes through a gap of a back surface of the refrigerator by a natural convection without flowing again from the hole 3 to the room by short-circuiting the gap of the back surface of the refrigerator and a gap between a bottom and a floor of the refrigerator and flows out from an upper part of a ceiling of the refrigerator to the front of the refrigerator.

    Abstract: PURPOSE:To eliminate an unevenness in distribution of temperature and perform a fine temperature control in a refrigerator capable of freezing, refrigerating and storing foods. CONSTITUTION:A calculation means 32 for calculating an increasing degree of temperature is arranged in a storing chamber so as to calculate a degree of increasing in temperature within the storing chamber. There is also provided a surrounding air temperature sensing means 31 so as to detect a surrounding air temperature. A fuzzy inference processor 34 performs a fuzzy logical calculation in response to an increasing degree of temperature, a surrounding air temperature and a control rule taken out of a memory 33 so as to calculate the set number of rotation of a compressor 17. The means 35 for calculating the set number of rotation adjusts the set number of rotation and controls the compressor 17.

    Abstract: PURPOSE:To restrict any noise produced from a fan in a freezing refrigerator equipped with a cold air circulation fan for forcedly circulating cold air cooled by a compressor by setting static pressure applied on the fan to be a predeter mined value or lower without being affected by the opening and closing of a damper device. CONSTITUTION:Control means 11 includes a microcomputer and is comprised of various electronic circuits such as compressor driving means 11a, revolution control means 11b, and opening/closing means 11c and the like. The control means 11 incorporates signals from refrigerator chamber temperature detector means 10, and fresh air temperature detector means 12 to control power supply to the compressor 4, the fan 6, and a damper device 8. Accordingly, any noise is restricted to a predetermined level or lower by changing the revolutions of the fan 6 correspondingly to a resistance change of a cold air circulation air passage.

    Abstract: PURPOSE:To prevent the temperature dispersion in a low-temperature chamber due to the returning cold air of the same chamber by a method wherein the returning cold air of a second refrigerating chamber, set so as to have a higher temperature than a first refrigerating chamber, is returned into a cooler through the first refrigerating chamber. CONSTITUTION:Cold air, discharged into a first refrigerating chamber 3, is returned into a cooling chamber 8 through a cold air returning duct 2a in a partitioning wall 2 while cold air, discharged into a low-temperature chamber 5, is distributed and discharged to the upper part of a vessel 20, received in a second refrigerating chamber 7, through a discharging passage 19 provided at the rear part of a partitioning wall 6, then, is released into the first refrigerating chamber 3 from a returning port 22a through a cold air returning duct 22, defined and formed at the rear part of a low-temperature chamber 5 and the first refrigerating chamber 3, and a cold air returning passage 21 in the partitioning wall 6 together with cold air, discharged from the discharging port 13b of a discharging duct 13 into a space between the outside of the vessel 20 and the inner wall of a second refrigerating chamber 7, then, is returned into the cooling chamber 8 through the cold air returning duct 2a in the partitioning wall 2. The returning cold air of the second refrigerating chamber 7 is returned into the cooling chamber 8 through the first refrigerating chamber 3 and, therefore, temperature dispersion in the low-temperature chamber 5 will never be generated by the returning cold air from the second refrigerating chamber 7.

    Abstract: PURPOSE:To regulate the temperature of each freezing chamber to be an adequate temperature by providing cold air return ducts for No.2 and No.3 freezing chambers, that pass through the inside of No.2 partition wall, a temperature control device located in the rear part of No.1 freezing chamber, and the inside of No.1 partition wall. CONSTITUTION:Cold air discharged to No.1 freezing chamber 3 through a dumper thermostat 14b is returned to a refrigerating device 8 through a cold air return duct A2a. Cold air discharged to No.2 freezing chamber 5 through a dumper thermostat 14a is distributed to No.2 and No.3 freezing chambers 5 and 7 through a convection port 6a on a partition wall 6, and then returned to the refrigerating device 8 through a cold air return duct B16 in No.2 partition wall 4, a cold air return duct C17 in a temperature control device 13, and a cold air return duct D18 in No.1 partition wall. Thus, by providing the cold air return ducts B16, C17, and D18 that pass through No.2 partition wall 4, the temperature control device 13, and No.1 partition wall 2, the returning cold air from No.2 and No.3 freezing chambers returns to the refrigerating device 8 without passing through No.1 freezing chamber. Therefore, even when No.1 or No.2 freezing chamber is assigned to a low temperature compartment, each compartment can be regulated to an adequate temperature without generating of irregular temperature zones and over-cooling.
