Moreover, after the __, magnetic and gravitational force can be utilized to move the movable core 26 forward. Γ The guide member 1 is placed on the horizontal frame, and is disposed on the front side of the ampere frame 24, and is placed on the slider 1 member 29 to hold the rear sill along the front and rear; ::=i face out The 30-out (4) is connected to the front end portion of the connecting piece 30a' and the connecting piece dust-extracting portion 26. Therefore, the shape of the square may be a downward-directed phase connection with respect to the movable iron core, and the front end of the film may be connected to the front end portion of the movable iron core 26 at the front end of the rear side of the door 10 The center of the direction is forwarded or “opens a little gap and is opposite.” and “When the movable iron core 26 turns around the corner 21”, the door 1G is pushed forward. Thus, the door 1Q is pressed against the magnet and is turned toward the opening direction. The door is provided with a movable handle 31 mounted on the door 10. Further, a slam-opening switch (not shown) such as a normally-closed micro-switch is slid on the cymbal 4, wherein The micro switch is turned on when the pull operation is controlled to move the handle 31. When the open switch is turned on, 1 to 2 (not shown): the coil 25 of the door opening device 22 is set to be energized for a predetermined time, for example, Ζ 11 200900646 28246pif.doc In the present embodiment configured as above, in order to open the door 10 of the freezing compartment 3, when the handle 31 is pulled, the coil 25 of the door opening device 22 is energized to oppose the compression spring 28. Bouncing the force to move the movable core 26 forward The suction lever 30 is pressed by the movable iron core 26 to abut against the door 10, and the door 10 is pushed forward and opened against the suction force of the magnet washer 21. Therefore, it is only necessary to gently When the handle 31 is pulled, the door 10 can be pulled forward. However, the door opening device 22 of the door 10 of the above-described freezer compartment 3 is difficult to form the ice making chamber 4 and the small freezing compartment 5 on the upper side of the freezer compartment 3. It is disposed outside the refrigerator and has to be disposed in the freezer compartment 3. Further, in the present embodiment, the door opening device 22 is disposed in a space existing behind the front lateral frame 23a of the top plate portion in the freezing compartment 3, In other words, since the door opening device 22 is required to be installed in the freezing compartment 3, the food storage space of the freezing compartment 3 is not reduced. In the embodiment, the pressing rod 30 is attached to the movable iron core 26 of the U-door device 22, and the pressing rod 30 is positioned downward from the center of the movable iron core 26 and is located below the front lateral frame 23a. Making the door opening device 22 not from the front frame 23a The rear space protrudes downward, or 'even if it protrudes, it is set to the minimum amount of protrusion. That is, the coil 25 of the door opening device 22 is cylindrical, and the movable iron core 26 is inserted into the coil 25. Therefore, When the movable iron core 26 is extended to the front as it is, and the movable iron core 26 is directly used to press the door 10, it is necessary to arrange the door opening device 22 to 12 200900646 28246pif.doc to make the coil 2:) The center of the container is located below the lower end of the front horizontal frame 23a. Thus, since the uppermost container is not in contact with the door opening device 22' when the door 10 is opened and closed, it is necessary to lower the height of the container 14, etc. The food storage space of the cold room 3 is narrowed. In contrast, in the present embodiment, the pressing rod 30 is biased downwardly and connected to the movable iron core %, and the door 1 is pulled out by the pressing rod 3, so that the opening door f 22 can be used. Stored in the front horizontal frame and the rear white space. Therefore, the storage space of the cold chamber 3 is not reduced, or it is reduced to a minimum even if it is small. (Embodiment 2) This is the second day of the implementation. In the second embodiment, the upper portion is different from the bottom portion (inner bottom portion) in the interior of the interior. Also, =:: layer: object 14. Among them, in the lowermost container, the second layer is wide or the whole part of the front part is formed to be deeper than the other parts, and the second=14& can be stored in the deep bottom, such as a bottle for beverages, etc. . In the closed state of 10, the portion of the inner bottom portion of the freezer compartment 3 which is located further rearward than the deep bottom portion (4) of the top layer of the grain hopper 14 forms a space in which the food can not be stored, and the door opening device 2 2 can be disposed in the space. Further, at the front end portion of the movable iron core 26 of the door device 22, an upward pressing force is attached, and the movable iron core 26 is slid forward by the pressing of the movable iron core 26. The pressing & sheet is in contact with the rear portion of the deep bottom portion 4a of the lowermost container 14, or it is opposed by a small gap. In the above configuration, when the coil 25 of the door opening device 22 is energized, the movable iron core 26 moves forward, and the deep bottom portion 14a of the lowermost container 14 is pressed by the pressing piece 32. Thereby, the door 〇 is pushed forward and opened - the front opening of the cold east chamber 3. • Even with such a configuration, it is possible to suppress the narrowing of the receiving space of the food in the freezing compartment 3, and to provide the door opening device 22 in the freezing compartment 3. Further, in the present embodiment, the door sill is opened by pressing the container 14, and since the yoghurt 14 is made of plastic, it is expected that elastic deformation is expected, so that excessive force is not applied to the movable iron core 26 when the door is opened. The load is applied to avoid excessive current flow in the coil 25. Further, since the upward pressing piece 32 is attached to the distal end portion of the movable iron core 26, the movable iron core 26 can be placed closer to the lower side than the container 14 of the pressing piece 32 = the pressing position, so that the door opening device 22 can be stored in the container. 14 in the small space below.
