The middle container 101 can be pulled out of the refrigerator independently from the lower container 100 by sliding the lower leg portion 101b and the upper leg portion 101d on the sliding surface 100b of the lower container 100 and the middle rail 127 in the front-rear direction. It is provided in the freezer compartment 10.

Such a middle container 101 is supported by the sliding surface 100b such that the lower leg portion 101b is located in front of the convex portion 100c of the lower container 100 when the heat insulating door 110 is closed as shown in FIG. The portion 101d is supported by the middle rail 127.

Then, when the insulation door 110 is opened from the closed state and the lower container 100 is pulled out of the refrigerator, the lower leg portion 101b comes into contact with the front side of the convex portion 100c of the lower container 100 and is pushed forward, and the middle container 101 The lower container 100 is also pulled out of the refrigerator (see FIG. 5).

Furthermore, when the lower container 100 moves rearward with the closing operation of the heat insulating door 110, the front wall 100a of the lower container 100 contacts the lower part of the front wall 101a of the middle container 101 and pushes it backward, causing the lower container 100 and the middle container 101 to move backward. is also moved to the rear and stored in the refrigerator.

The upper container 102 is arranged above the middle container 101 and has a box shape with an upward opening and a bottom surrounded by a front wall 102a, left and right side walls, and a rear wall. It is placed at the top of the list.

As with the middle container 101, the upper container 102 has a smaller protrusion from the bottom surface to the top end of the front wall 102a than the protrusion from the bottom surface to the top ends of the left and right side walls and rear wall. In addition, the front ends of the left and right side walls are inclined so that the amount of protrusion from the bottom surface gradually decreases as they move forward. This increases the gap between the upper container 102 and the insulating partition wall 16 at the front end of the upper container 102.

A flange 102c protrudes from the upper end of the front wall 102a and slopes downward toward the front. The flange portion 102c is provided parallel to the inclined portion provided at the front end portions of the left and right side walls so as to extend the inclined portion forward.

The left and right side walls of the upper container 102 are provided with leg portions 102d that protrude outward in the width direction. The legs 102d are provided along the front-rear direction on the left and right side walls of the upper container 102, and placed on upper rails 128 (see FIG. 5) provided along the front-rear direction on the left and right side walls of the inner box 4 that partitions the freezer compartment 10. has been done. That is, the upper container 102 is supported by the left and right side walls of the freezer compartment 10 via the upper rail 128.

The upper container 102 is provided in the freezer compartment 10 so that it can be pulled out to the outside independently of the lower container 100 and the middle container 101 by sliding the legs 102d in the front-rear direction on the upper rails 128.

(6) Opening/closing operation of the heat insulating door 110 Next, the opening/closing operation of the heat insulating door 110 will be explained.

As shown in FIG. 4, in the closed state where the heat insulating door 110 closes the front opening of the freezer compartment 10, the sealing member 117 is brought into close contact with the periphery of the opening of the refrigerator body 2 by the magnetic force of the magnet disposed inside. , the space between the heat insulating door 110 and the front opening of the freezer compartment 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 this embodiment, 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 part 118 forward in order to open the heat insulation door 110 from such a closed state, the position where the container support 120 is fixed (screw fixing part 121a) on the heat insulation door 110 is located between the lower container 100 and the handle part 118. Due to the weight of the stored items stored in the middle container 101, forward movement is restricted. Therefore, when the handle portion 118 is pulled forward, a deforming force is applied to the insulation door 110 such that the lower side moves backward. The deformation movement of the heat insulating door 110 is restricted by contacting the front wall 100a of the heat insulating door 110.

Furthermore, in this embodiment, since 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, the heat insulating door 110 is moved toward the center in the vertical direction. the top of the door will move 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 from the upper end of the heat insulating door 110 downward. Then, when the lower side of the heat insulating door 110 moves backward by a predetermined amount, the protrusion 140 provided on the inner door 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 this embodiment, since the heat insulating door 110 is provided with the protrusion 140 that protrudes toward the front wall 100a of the lower container 100, when the user pulls the handle portion 118 forward, Even if a deforming force is applied to the heat insulating door 110 to cause the lower side to move rearward, the protrusion 140 can prevent the heat insulating door 110 from being excessively deformed due to contact with the front wall 100a of the lower container 100. can.

In this embodiment, when the gap 141 is provided between the protrusion 140 and the front wall 100a of the lower container 100, when the handle part 118 is pulled forward from the closed state of the heat insulating door 110, the upper part of the heat insulating door 110 moves forward. The lower part of the heat insulating door 110 moves rearward so as to eliminate the gap 141. Therefore, even if the sealing member 117 provided at the upper end of the insulating door 110 is torn off from the refrigerator main body 2, the force required to open the insulating door 110 (opening force) will be significantly reduced, even if the insulating door 110 is large. can be reduced to When the lower side of the insulation door 110 moves backward by a predetermined amount, the protrusion 140 provided on the inner door plate 112 of the insulation door 110 comes into contact with the front wall 100a of the lower container 100, causing the insulation door 110 to rotate excessively. It is possible to prevent deformation and damage of the heat insulating door 110 and the container support 120.

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

Moreover, if the position where the container support 120 is fixed to the heat insulation door 110 is below the vertical center of the heat insulation door 110, a large load will be applied to the position of the heat insulation door 110 where the container support 120 is fixed. Even if the heat insulating door 110 and the container support 120 are deformed so as to create a gap between the lower end of the heat insulating door 110 and the refrigerator main body 2, this can be suppressed.

In other words, when the weight of the stored items stored in the lower container 100 and the middle container 101 is large and a large load is applied to 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 is above the vertical center of the insulating door 110, the insulating door 110 and the container support 120 are deformed such that the upper part of the insulating door 110 moves backward and the lower part of the insulating door 110 moves forward. . As a result, the sealing member 117 may separate from the refrigerator main body 2 at the lower end of the heat insulating door 110, and the freezer compartment 10 may be opened. If the position where the container support 120 is fixed to the heat insulating door 110 is below the vertical center of the heat insulating door 110 as in this embodiment, even if the weight of the stored items becomes large, the lower part of the heat insulating door 110 will be It becomes difficult to move forward, and it is possible to prevent the freezer compartment 10 from opening at the lower end of the heat insulating door 110.

In this embodiment, when providing an inclined surface 142 that slopes downward toward the rear on the upper side of the protrusion 140 protruding from the freezer compartment 10 side of the heat insulating door 110, the lower container 100 is attached to the upper flange of the container support 120. Even if the bottom surface of the lower container 100 hits the upper side of the protrusion 140 when supported by the portion 122a, the lower container 100 can be guided rearward by the inclined surface 142 and mounted in a predetermined position.

In the present embodiment, an upper container 102, a middle container 101, and a lower container 100 are arranged vertically in the freezer compartment 10, and the lower container 100 placed at the bottom is the largest in the vertical direction and is fixed to the heat insulating door 110. The upper container 102 is vertically larger than the middle container 101, and when supported on the inner wall of the freezer compartment 10, the inside of the freezer compartment 10 is separated by the upper container 102, the middle container 101, and the lower container. Since the freezer compartment 100 can be divided into upper and lower sections, the volume of the freezer compartment 10 can be increased without impairing usability. In addition, the largest lower container 100 is supported by a container support 120 fixed to the heat insulating door 110, making it easy to set a large forward draw amount, and the second largest upper container 102 is supported in the freezer compartment 10. By doing so, it is possible to reduce the load acting on the position of the heat insulating door 110 where the container support body 120 is fixed.

In this embodiment, when the front walls 102a, 101a of the upper container 102 and the middle container 101 are provided with collars 102c, 101c that slope downward as they move forward, the upper container 102 and the middle container 101 At the front end of the container 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 air outlet 34 into the freezer compartment 10 flows from the rear to the front between the upper container 102 and the heat insulating partition wall 16 and between the middle container 101 and the upper container 102, and then passes through the upper container 102. Also, it becomes difficult to accumulate at the front end of the middle container 101, and the freezing compartment 10 can be cooled uniformly.

In such a case, the cold air blown out from the air outlet 34 tends to hit the heat insulating door 110 in front of the flanges 101c and 102c, and condensation tends to occur on the outer side (front side) of the refrigerator at that part. As such, when the thickness t1 of the heat insulating material 116 of the heat insulating door 110 in front of the flanges 101c and 102c is larger than the thickness t0 of the heat insulating material 116 in front of the lower container 100, condensation on the heat insulating door 110 can be suppressed. Can be done.

In this embodiment, as shown in FIG. 6, a case has been described in which the protrusions 140 are provided at both left and right ends of the lower part of the heat insulating door 110, but the present invention is not limited thereto. For example, one protrusion 140 may be provided at the center in the left and right direction of the heat insulating door 110, one protrusion 140 may be provided at both ends and the center in the left and right direction, or the protrusion 140 may extend from one end in the left and right direction to the other end. The protrusion 140 can be provided at any position in the left-right direction of the heat insulating door 110, such as by providing a striped protrusion 140. When the user pulls one end of the handle part 118 in the left and right direction forward, a force acts on the heat insulation door 110 to deform the heat insulation door 110 so that the lower part of the other end in the left and right direction moves rearward. When the door 110 has the protrusions 140 at least at both ends in the left and right direction, the protrusions 140 come into contact with the front wall 100a of the lower container 100 at a relatively early stage of the deformation of the heat insulating door 110, making it possible to suppress the deformation of the heat insulating door 110. can.

Furthermore, in this 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 when the user is not applying force to the heat insulating door 110, The protrusion 140 may be provided so as to come into contact with the wall 100a, or a member having cushioning properties may be provided in the gap 141. When a member having cushioning properties is provided in the gap 141, the opening force required to open the heat insulating door 110 as described above can be significantly reduced, and the protrusion 140 comes into contact with the front wall 100a of the lower container 100. It can soften the impact of time.
