The upper leg portion 101d is placed on a middle rail 127 (see FIG. 5) provided on the left and right side walls of the inner box 4 that partitions the freezing chamber 10 in the front-rear direction.

In the middle container 101, the lower leg 101b and the upper leg 101d slide the sliding surface 100b of the lower container 100 and the middle rail 127 in the front-rear direction so that the lower container 101 can be pulled out of the refrigerator independently of the lower container 100. It is provided in the freezing chamber 10.

In such a middle stage container 101, in the closed state of the heat insulating door 110 as shown in FIG. 4, the lower leg portion 101b is supported by the sliding surface 100b so as to be located in front of the convex portion 100c of the lower stage container 100, and the upper leg is supported. The portion 101d is supported by the middle rail 127.

Then, when the heat insulating door 110 is opened from the closed state and the lower container 100 is pulled out of the refrigerator, the lower leg portion 101b abuts on the front side of the convex portion 100c of the lower container 100 and is pushed forward, and the middle container 101 is pushed forward. Is also pulled out of the refrigerator together with the lower container 100 (see FIG. 5).

Further, when the lower container 100 moves backward with the closing operation of the heat insulating door 110, the front wall 100a of the lower container 100 comes into contact with the lower part of the front wall 101a of the middle container 101 and is pushed backward, and the middle container 101 is pushed together with the lower container 100. Also moves backward and is stored in the refrigerator.

The upper container 102 is arranged above the middle container 101 and has a bottomed box shape that is surrounded by the front wall 102a, the left and right side walls, and the rear wall and opens upward. It is located at the top of the list.

Similar to the middle container 101, the upper container 102 has a protrusion amount smaller than the protrusion amount from the bottom surface to the upper end of the front wall 102a from the bottom surface to the left and right side walls and the upper end of the rear wall. Further, the front end portions of the left and right side walls are inclined so that the amount of protrusion from the bottom surface gradually decreases toward the front. As a result, the distance between the upper container 102 and the heat insulating partition wall 16 is widened at the front end of the upper container 102.

At the upper end of the front wall 102a, a flange portion 102c that inclines downward toward the front protrudes. The flange portion 102c is provided in parallel with the inclined portion so as to extend the inclined portion provided at the front end portion of the left and right side walls forward.

Legs 102d protruding outward in the width direction are provided on the left and right side walls of the upper container 102. The legs 102d are placed on the upper rail 128 (see FIG. 5) provided on the left and right side walls of the upper container 102 along the front-rear direction and provided on the left and right side walls of the inner box 4 for partitioning the freezing chamber 10 in the front-rear direction. Has been done. That is, the upper container 102 is supported on the left and right side walls of the freezing chamber 10 via the upper rail 128.

The upper container 102 is provided in the freezing chamber 10 so that the legs 102d can be pulled out of the refrigerator independently of the lower container 100 and the middle container 101 by sliding the upper rail 128 in the front-rear direction.

(6) Opening / Closing Operation of Insulated Door 110 Next, the opening / closing operation of the heat insulating door 110 will be described.

As shown in FIG. 4, in the closed state where the heat insulating door 110 closes the front opening of the freezing chamber 10, the sealing member 117 is brought into close contact with the peripheral edge of the opening of the refrigerator body 2 by the magnetic force of the magnet arranged inside. , The space between the heat insulating door 110 and the front opening of the freezing chamber 10 is sealed. At this time, a part of the weight of the stored items stored in the lower container 100 and the middle container 101 acts on the position where the container support 120 is fixed in the heat insulating door 110. That is, in the present embodiment, a part of the weight of the stored items stored in the lower container 100 and the middle container 101 acts on the screw fixing portion 121a.

When the user pulls the handle portion 118 forward in order to open the heat insulating door 110 from such a closed state, the position where the container support 120 is fixed (screw fixing portion 121a) in the heat insulating door 110 is the lower container 100 and. The forward movement is restricted due to the weight of the stored items stored in the middle container 101. Therefore, when the handle portion 118 is pulled forward, a deforming force acts on the heat insulating door 110 so that the lower side moves rearward, but the protrusion 140 provided on the door inner plate 112 of the heat insulating door 110 is the lower container 100. The front wall 100a of the heat insulating door 110 is in contact with the front wall 100a to regulate the deformation and movement of the heat insulating door 110.

Further, in the present embodiment, since the gap 141 is provided between the protrusion 140 and the front wall 100a of the lower container 100, when the handle portion 118 is pulled forward, the heat insulating door 110 with respect to the central portion in the vertical direction. The upper part of the door moves forward. That is, the heat insulating door 110 rotates around the position where the container support 120 is fixed, with the upper side moving forward and the lower side moving backward so as to eliminate the gap 141.

As a result, the sealing member 117 provided on the heat insulating door 110 is peeled off from the refrigerator main body 2 downward from the upper end of the heat insulating door 110. Then, when the lower side of the heat insulating door 110 moves rearward by a predetermined amount, the protrusion 140 provided on the door inner plate 112 of the heat insulating door 110 comes into contact with the front wall 100a of the lower container 100.

(7) Effect In the refrigerator 1 of the present embodiment, the heat insulating door 110 is provided with a protrusion 140 projecting toward the front wall 100a of the lower container 100, so that when the user pulls the handle portion 118 forward. Even if a deformation force such that the lower side moves rearward acts on the heat insulating door 110, it is possible to prevent the protrusion 140 from coming into contact with the front wall 100a of the lower container 100 and excessively deforming the heat insulating door 110. can.

In the present embodiment, when a gap 141 is provided between the protrusion 140 and the front wall 100a of the lower container 100, when the handle portion 118 is pulled forward from the closed state of the heat insulating door 110, the upper part of the heat insulating door 110 is moved forward. And the lower part of the heat insulating door 110 moves backward so as to eliminate the gap 141. Therefore, it is peeled off from the refrigerator main body 2 from the sealing member 117 provided at the upper end of the heat insulating door 110, and even when the heat insulating door 110 is large, the force (door opening force) required for opening the heat insulating door 110 is significantly increased. Can be reduced to. Then, when the lower side of the heat insulating door 110 moves rearward by a predetermined amount, the protrusion 140 provided on the door inner plate 112 of the heat insulating door 110 comes into contact with the front wall 100a of the lower container 100, and the heat insulating door 110 rotates excessively. It is possible to prevent the heat insulating door 110 and the container support 120 from being deformed or damaged.

In the present embodiment, when the position where the container support 120 is fixed to the heat insulating door 110 is lower than the vertical center portion of the heat insulating door 110, the distance from the position where the container support 120 is fixed to the handle portion 118 is set. It can be made larger and smaller, and the upper part of the heat insulating door 110 can be moved forward to open the door.

Moreover, when the position where the container support 120 is fixed to the heat insulating door 110 is lower than the central portion in the vertical direction of the heat insulating door 110, a large load acts on the position where the container support 120 of the heat insulating door 110 is fixed. However, it is possible to prevent the heat insulating door 110 and the container support 120 from being deformed so as to form a gap between the lower end of the heat insulating door 110 and the refrigerator body 2.

That is, when the weight of the stored items contained in the lower container 100 and the middle container 101 is large and a large load acts on the position where the container support 120 of the heat insulating door 110 is fixed, the position where the container support 120 is fixed. Is above the central portion in the vertical direction of the heat insulating door 110, the heat insulating door 110 and the container support 120 are deformed so that the upper part of the heat insulating door 110 moves backward and the lower part of the heat insulating door 110 moves forward. .. As a result, at the lower end of the heat insulating door 110, the sealing member 117 may be separated from the refrigerator main body 2 and the freezing chamber 10 may be opened. If the position where the container support 120 is fixed to the heat insulating door 110 as in the present embodiment is below the central portion in the vertical direction of the heat insulating door 110, the lower part of the heat insulating door 110 is located even if the weight of the stored item is increased. It becomes difficult to move forward, and it is possible to prevent the freezing chamber 10 from opening at the lower end of the heat insulating door 110.

In the present embodiment, when the inclined surface 142 is provided above the protrusion 140 protruding from the freezing chamber 10 side of the heat insulating door 110 so as to incline downward toward the rear, the lower container 100 is placed on the upper collar of the container support 120. Even if the bottom surface of the lower container 100 hits the upper side of the protrusion 140 when the lower container 100 is supported by the portion 122a, the lower container 100 can be guided backward by the inclined surface 142 and mounted at a predetermined position.

In the present embodiment, the upper container 102, the middle container 101, and the lower container 100 are provided side by side in the freezing chamber 10, and the lower container 100 arranged on the lowermost side is the largest in the vertical direction and is fixed to the heat insulating door 110. When the upper container 102 is supported by the container support 120 and is larger in the vertical direction than the middle container 101 and is supported by the inner wall of the freezing chamber 10, the inside of the freezing chamber 10 is filled with the upper container 102, the middle container 101 and the lower container. Since it can be divided into upper and lower parts by 100, the volume of the freezing chamber 10 can be increased without impairing usability. Further, the largest lower container 100 is supported by the container support 120 fixed to the heat insulating door 110 so that the amount of forward drawer can be easily set, and the second largest upper container 102 is supported by the freezing chamber 10. It is possible to reduce the load acting on the fixed position of the container support 120 of the heat insulating door 110.

In the present embodiment, when the upper ends of the front walls 102a and 101a of the upper container 102 and the middle container 101 are provided with flange portions 102c and 101c that are inclined downward toward the front, the upper container 102 and the middle container are provided. At the front end of the 101, the distance between the upper container 102 and the heat insulating partition wall 16 and the distance between the middle container 101 and the upper container 102 become wider. Therefore, the cold air blown out from the outlet 34 to the freezing chamber 10 flows between the upper container 102 and the heat insulating partition wall 16 and between the middle container 101 and the upper container 102 from the rear to the front, and then the upper container 102. In addition, it becomes difficult for the container to stay at the front end of the middle container 101, and the freezing chamber 10 can be cooled uniformly.

In such a case, the cold air blown out from the outlet 34 tends to hit the heat insulating door 110 in front of the flange portions 101c and 102c, and dew condensation tends to occur on the outside (front side) of the portion. As described above, when the thickness t1 of the heat insulating material 116 of the heat insulating door 110 in front of the flange portions 101c and 102c is larger than the thickness t0 of the heat insulating material 116 in front of the lower container 100, dew condensation is suppressed on the heat insulating door 110. Can be done.

In the present embodiment, as shown in FIG. 6, the case where the protrusions 140 are provided on the left and right ends of the lower portion of the heat insulating door 110 has been described, but the present invention is not limited to this. For example, one protrusion 140 may be provided at the central portion of the heat insulating door 110 in the left-right direction, one protrusion 140 may be provided at both ends and one central portion in the left-right direction, or the heat insulating door 110 extends from one end portion in the left-right direction to the other end portion. The protrusions 140 can be provided at arbitrary positions in the left-right direction of the heat insulating door 110, such as by providing the streak-shaped protrusions 140. When the user pulls one end of the handle 118 in the left-right direction forward, a force that deforms the heat-insulating door 110 acts so that the lower end of the other end in the left-right direction moves rearward with respect to the heat-insulating door 110. When there are protrusions 140 at least at both ends of the door 110 in the left-right direction, the protrusions 140 abut on the front wall 100a of the lower container 100 at a relatively early stage of deformation of the heat insulating door 110, and the deformation of the heat insulating door 110 can be suppressed. can.

Further, in the present embodiment, the case where the gap 141 is provided between the protrusion 140 and the front wall 100a of the lower container 100 has been described, but in a state where the user does not apply force to the heat insulating door 110, the front of the lower container 100 is provided. The protrusion 140 may be provided so as to abut on the wall 100a, or a member having a cushioning property may be provided in the gap 141. When a member having a cushioning property is provided in the gap 141, the door opening force required for opening the heat insulating door 110 as described above can be significantly reduced, and the protrusion 140 abuts on the front wall 100a of the lower container 100. It can soften the impact of time.
