    Abstract: PURPOSE:To facilitate manufacturing and prevent dewing, by rotatably supporting a first deflecting plate at an air blow-off port and providing an arc-shaped second deflecting plate to which heat insulators are bonded so that a setp part is formed on the surface of the plate. CONSTITUTION:When the first deflecting plate 16 is set downward, the air along a heat insulator 20 for the second deflecting plate 18 is oriented to another heat insulator 21 by the Coanda effect due to the step part 22 so that the air proceeds in the direction of the arrow C under the action of the deflecting plate 16. When the first deflecting plate 16 is set in the position shown by the full line in Fig., a horizontal flow as shown by the arrow F is caused as a whole by the confluence action with the flow D on an oblique part 5 and the attraction by the flow E on the heat insulator 20. Because the step part 22 of the second deflecting plate 18 is formed by the heat insulators 20, 21 different in thickness and attached to the deflecting plate, the curved surface of the deflecting plate 18 can be formed by one operation of a metal mold and dew is prevented from scattering.

    Abstract: PURPOSE:To make a systematic combination of an unclocking of or a locking of a door and a temperature changing-over operation and prohibit the changing-over except the needed time by a method wherein a segmented chamber in a rocker can be changed over to more than 2 temperatures, the changing-over time is limited and the door can be opened for a specified period of time in response to a signal of a door opening or closing operation. CONSTITUTION:A refrigeration rocker device 3 and a dry rocker device 4 have 4 to 3 chambers of a thermal insulation chamber 5 and a segmented chamber 6 for storing home-delivered objects or the like. The thermal segmented chamber 5 and the segmented chamber 6 are constructed such that the thermal insulation door 7 and the door 8 are pivoted in such a way as they can be freely opened or closed, the door is provided with a locking device 9 to be engaged with a main body of the device. A control device 2 operates the locking device 9 with a switching action of the lamp and door switch 14 being applied as a signal. Selector switches 32, 33 and 34 for setting the segmented chambers 5, 5a, 5b and 5c in the refrigeration rocker device 3 to 5 deg., 0 deg.C and -18 deg.C, for example, can be operated only for a specified period of time in response to a signal from the locking device 9 operated when the cool-kept home-delivered objects are stored, resulting in that the initial set temperature can be kept during a period of storing the home-delivered objects. That is, as the temperature is once set, the switch for use in changing-over operation is even touched, a possibility of changing an operation is not present.

    Abstract: PURPOSE:To even the reach of blown-off air in a wide range by arranging automatic rocking louvers (which deflect the blow-off direction continuously) and a fan motor (capable of continuous change in its revolution number) at an air blow-off port and increasing the revolution number as the blow-off resistance on the louvers increases. CONSTITUTION:Automatic rocking louvers 10 for continuous deflection of the blow- off direction are fitted at a blow-off port 3. A contact member 19a of a slide type variable resistor 19 is fixed on the front face of a cam holder 14b of the louvers 10, and is slid in association with the rocking of the cam holder 14b. With the contact member 19a at the left or the right side of the resistor 19, the resistance value is low and a fan motor 8 rotates at high speed, so that the blow-off air reaches a predetermined distance regardless of its impingement on the louvers 10. With the member 19a at the center of the resistor 19 and with the louvers 10 parallel with the front face, the fan motor 8 rotates at normal speed so as to even the reach of blown-off air.
