Abstract

PURPOSE:To move a rack smoothly even when the weight of food stuff, put on the rack, is large and facilitate the storage and delivery of the food stuff by moving the rack, suspended in a refrigerator, forwardly and rearwardly by a motor control means driving a motor forwardly and backwardly. CONSTITUTION:Rails 11, supporting slidably rollers 19 projected from the side surfaces of the rack 5 of a refrigerator, are extended in grooves 13 formed on both side walls of an inner casing 12 forwardly and rearwardly so as to be opposed. A DC motor 14 is embedded in the insulating material 16 at the fore part of both side walls of the inner casing 12, which is opposed to the lower part of the fore end of the rail 11. A pinion 8, attached to the rotary shaft of the DC motor 14, is meshed with a rack 18 formed on both side of the lower surface of the rack 5 and the rack 5 is moved forwardly and rearwardly by turning the DC motor 14 forwardly and backwardly. Accordingly to this method, the rack may be moved smoothly even when the weight of food stuff put on the rack is large whereby the food stuff may be stored and delivered easily.

Next, the operation will be explained. Shelves (5) as shown in Figures 1 and 3
It is assumed that the refrigerator is stored at a predetermined position in the refrigerator compartment (2). When the refrigerator compartment door (4) is opened, the contact point (39)
(40) closes. Next, switch (
26), the microcomputer (42) energizes the coil (43) and closes the switch (36), causing no current to flow in the upward direction in FIG. 5 to the motors (14) and (15). As a result, the motors (14), (ts) rotate, the binions (8), (8) rotate in the direction of pulling out the shelf (5), and the shelf (5>) is pulled out to the front side.

Next, when the switch (27) is operated from this state, the microcomputer (42) energizes the coil (44) and closes the switch (37). This allows the motor (14)
, (15) is supplied with a current in the downward direction in Fig. 5,
The motors (14) and (15) rotate in the opposite direction to the above and move the shelf (5).
) is retreated and stored in the refrigerator compartment (2). When the stopper (20) comes into contact with the microswitch (23), the microcomputer (42) switches to the fill (44).
Turn off the power to +I-, open the switch (37), and stop the motors (14) and (15). In this state, the shelf (5) is stored at a predetermined position within the refrigerator compartment (2).
