摘要： PROBLEM TO BE SOLVED: To provide a fan holding structure not requiring much labor and time for adjustment in order to avoid the resonance, securing a wide degree of freedom in designing, and easy to execute the molding despite its small size. SOLUTION: A fan motor holding part 2 to accommodate a fan motor 1 is made of resin and fixed to a cabinet 4 through two stays 3, and a plurality of weight mounting holes 6 for mounting of weights 5 as rod-shaped piece made of metal or resin are formed at the peripheral edge 2a partially of the holding part 2. A vibration isolating member 7 of rubber, etc., is interposed between the holding part 2 and fan motor 1. The holding part 2 is fitted with a cover 8 for fixation of fan motor, and a vibration isolating member 9 is alike interposed between the cover 8 and fan motor 1. An impeller 10 is mounted on the rotary shaft of the fan motor 1, and when it 1 is operated, the generated vibration may be identical to the natural frequency of the holding part 2 to cause generation of resonance. Therefore, weight 5 is inserted in any hole 6 and fastened so as to dislocate the natural frequency of the holding part 2.

摘要： PROBLEM TO BE SOLVED: To reduce noises of a blower without increasing the number of component parts by forming a cold air distribution guide plate projecting to the side of the blower and leading cold air in all directions at a portion of a cold air guide plate, which is positioned in front of the blower. SOLUTION: Cold air sucked through a cold air suction port 13 provided in a cold air guide plate 20 passes through a cooler 6 positioned between a bell-mouth 21 and an inner case 5 and is blown to a cold air distribution guide plate 14 formed integrally with the cold air guide plate 20 and conically projected to the side of a fan 11 for a blower, by the fan 11 for the blower, which is rotated by a motor 10 for the blower. With such an arrangement that the cold air distribution guide plate 14 is formed conically and integrally with the cold air guide plate 20 in front of the blower, the turbulent flow of the cold air does not occur. Further, the strength of the cold air guide plate 20 is increased to reduce the vibration thereof, and, furthermore, the number of component parts required becomes smaller.

摘要： PURPOSE:To reduce a cooling chamber of a cooler and improve a volumetric efficiency by a method wherein a heat transmitting pipe having refrigerant passed therein is disposed in the same plane as that of a heat transmitting plate, a blower is disposed in the cooling chamber in opposition to the heat transmitting surface of the cooler and an agitating vane opposing against the heat transmitting plane is disposed on the disk. CONSTITUTION:As a blower 13 is rotated by a motor 12, air acting as cooling medium in a storing chamber 2 is driven by a centrifugal force generated by agitating vanes 13b, air is flowed from a central opening of a cooler 14 into a space between the cooler 14 and the blower 13 and the air flows from inside toward an outside part and on a heat transmitting surface of the cooler 14. With such an arrangement, the cooler can be made thin, the cooling chamber 3 is also reduced in its size and a volumetric efficiency of a refrigerator is improved. In addition, even if a distance between the heat transmitting surface of the cooler 14 and an end surface of each of the agitating vanes 13b facing against the cooler 14 is made smaller than that of a rising point of gradient to increase a convection heat transmitting efficiency as this distance is decreased, a similar effect may also be attained and further the heat transfer is improved to enable the cooler 14 to be reduced in its size.
