Abstract: PURPOSE:To increase the amount of foods stored in a freezing chamber and to prevent overcooling of a low temperature chamber by a method wherein a refrigerator body is laterally divided into two compartments, the upper part of one of the compartments forms a first freezing chamber, the upper part of the other forms a second freezing chamber adjacent to the first freezing chamber and the central part thereof forms a low temperature chamber adjacent to the first freezing chamber. CONSTITUTION:A first freezing chamber 21 is arranged in the upper part of one of the two compartments into which a refrigerator body is laterally divided by a vertical partition 20, a first freezing chamber 22 is arranged at the central part thereof, and a second refrigerating chamber 25 in the lower part thereof. A second freezing chamber 27 is arranged at the upper part of the other laterally adjacent to the first freezing chamber 21, and a low temperature chamber 28 is located at the lower part thereof laterally adjacent to the first freezing chamber 22. Further, a third refrigerating chamber 31 is arranged under the lower temperature chamber 28 laterally adjacent to the first and second refrigerating chambers 22 and 25. Further, since the first and second freezing chambers 21 and 27 are located in juxtaposition at the upper part of a refrigerator body 19, an amount of foods contained in the whole of the freezing chambers is increased. The thermal effect of other chambers on the low temperature chamber 28, effective in preserving fresh fish and meat, is reduced.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of component parts and material to be used and enable a light weight heat insulated door to be attained by a method wherein some foamed heat insulated material is filled in a space between an outer plate and an inner plate of a box in which the outer plate, the inner plate, a top plate end part and a column-like protrusion at a bottom surface end part opposing against it are integrally formed. SOLUTION: A top surface end part of resin heat insulated door 12 formed into a box member by a blow formation process and its opposing bottom surface end part are formed with column-like protrusions 13 and after urethane heat insulated material 14 is fed into the box member of the heat insulated door 12 through an air pressure feeding port 15 during a blow forming process the heat insulated material is foamed and filled and then the air pressure feeding port 15 is sealed by a cap 16. In addition, the protrusion 13 of the heat insulated door 12 is passed through hinge holes in an upper hinge plate and a lower hinge plate fixed to a main body of a refrigerator and fixed there. This heat insulated door is constructed such that the outer plate, the inner plate and a hinge engaging part are made of the same resin and integrally molded, so that the number of component parts is less, light weight and an opening or closing operation can be carried out smoothly.

Abstract: PROBLEM TO BE SOLVED: To improve operation reliability of a compressor when a power source is closed and to shorten a time in which temperature in a refrigerator chamber during interruption to service is restored to a given temperature. SOLUTION: Right after making of a power source, energization to a compressor 4 and a blast fan 7 is started, and when a temperature DS of a room temperature sensor 14 and a temperature DF of a refrigerating chamber temperature sensor 9 are both higher than a set temperature Dmax, and when at a point of time when a given time ▵T1 elapses, further, a temperature DC of a condenser temperature sensor 23 exceeds an upper limit set value DCmax, a damper device 10 is forcibly closed a given time ▵T2 thereafter, ordinary control is executed.

Abstract: PURPOSE: To shorten a period of time for the returning to specified temperatures of a freezer chamber and refrigerator chamber by a method wherein when a defrosting completion-detecting means detects a temperature which is a set temperature or higher at the time of turning-on of the power, the operation of a blowing fan is stopped for a previously set period of time only when the defrosting completion-detecting means detects a condensation temperature sensor upper limit set temperature or higher after a specified period of time has passed. CONSTITUTION: When a detected temperature of a defrosting completion-detecting means 9 right after the start of operations of a compressor 4 and blowing fan 7 is a set value or higher at the time of turning on of a power source, i.e., when it is detected that the outside air temperature is high, and a cooling is not done yet, a judgement whether a detected temperature of a condenser temperature sensor 24 is an upper limit set value or higher or not is performed after a specified period of time has passed after the detection. Then, when the detected temperature is the upper limit set value or higher, i.e., under a state wherein an input load to the compressor is too large, power is prevented from being connected to the blowing fan 7, and the blowing fan is made to stand by until a previously set period of time passes. Then, after the specified period of time has passed, the power connection to the blowing fan 7 is resumed, and the control is transferred to a normal control routine.

Abstract: PURPOSE: To improve reliability of operation of a compressor when a power supply is turned on, and reduce time required for the temperature in a refrigerator to return to a predetermined temperature upon power interruption. CONSTITUTION: When the temperature DA of a condenser temperature sensor 23 and the temperature DF of a freezing chamber temperature sensor 9 are both set at a temperature Dmax or higher when power supply to a compressor 4 and an air fan 7 is started just after a power supply is turned on, when the temperature DC of the condenser temperature sensor 23 after the lapse of a predetermined time ΔT1 is an upper limit set value DCmax or higher, the air fan 7 is kept at a power interruption state thereafter only for a predetermined time ▵T2, after the power interruption state normal control is executed.

Abstract: PROBLEM TO BE SOLVED: To provide a manifold with a built-in thermoelectric module to increase an opportunity for a heating medium to make contact with the heat transfer surface of the thermoelectric module, be high in cooling efficiency and secure reliability. SOLUTION: Since an impeller 13 and a rotor 17 are integrally formed and formed of a magnetic substance, a weight balance is stable and since the efficiency of heat-exchange with a heat transfer surface 12a is improved, cooling efficiency is improved. Further, since a bearing part 19 of the impeller 13 is molded by using two parts through a space part 20, a heat medium is positively inputted in a gap between a spindle 18 and a bearing part 19, whereby wear of the spindle 18 is reduced and a manifold with a built-in thermoelectric module having further improved reliability is provided.
