The first and second storage cases 58 and 59 are pulled out to the rear end of the refrigerator body 1, and the third storage case 60 is pulled out to the place where the rear end wall is located inside the refrigerator body 1. The structure is like a refrigerator.

Further, as shown in FIG. 32, a mountain-shaped protrusion 71a is formed in the vicinity of the front end of the main body rail 71 of the side wall portion of the freezing chamber 18, and when the third-stage storage case 60 is pulled out in a pedestal shape, this mountain is formed. The main body sliding protrusion 70 provided on the rearmost side surface of the third-stage storage case 60 is in contact with the shape protrusion 71a, but if the third-stage storage case 60 is manually pulled out in that state, the above The second protrusion 68b gets over the mountain-shaped protrusion 71a and moves to the second guide rail portion 69 of the second-stage storage case 59, and is slidable forward on the second-stage storage case 59. Then, when the third-stage storage case 60 is further pulled out, as shown in FIGS. 39 and 40, the rear end wall of the third-stage storage case 60 can also be pulled out to the outside of the refrigerator main body 1.

The functions and effects of the refrigerator configured as described above will be described below.

First, the cooling of the entire refrigerator will be briefly described.

When the temperature of the refrigerator compartment 14 becomes higher than the set temperature, the refrigerator drives the compressor 27 and the cooling fan 25, and the cooling fan 25 supplies the cold air generated by the cooler 24 to each chamber.

The cold air from the cooling fan 25 is supplied from the refrigerating cold air supply port 22 to the refrigerating chamber duct 28 via the refrigerating chamber damper 37, and from the side discharge ports 28e opened on the left and right side surfaces of the refrigerating chamber duct 28 to the refrigerating chamber 14. The inside of the blow-out refrigerating chamber 14 is cooled.

Further, the cold air from the cooling fan 25 is supplied to the vegetable compartment 17 via the vegetable compartment duct 29 to cool the inside of the vegetable compartment 17.

Further, the cold air from the cooling fan 25 is supplied from the freezing cold air outlet 23a to the freezing chamber 18, the ice making chamber 16, and the second freezing chamber 15 located in front of the cooling chamber to cool each of these chambers.

Next, the action and effect of the shelf board 19 in the refrigerator compartment 14 will be described.

A wide variety of foods are stored in the refrigerating chamber 14, and among these various foods, when small foods are stored in the back of the shelf board 19, the refrigerating chamber duct 28 protruding forward There is a risk of falling from the gap created between the refrigerator compartment and the back wall 14a.

However, in this refrigerator, since the gap portion is closed by the protruding piece 33 provided at the rear end edge of the shelf plate, it is possible to prevent the refrigerator from falling.

In particular, the gap formed behind the rear end edge of the uppermost shelf board 19 has a shape in which the refrigerating chamber duct 28 bends forward from the refrigerating chamber back wall 14a and protrudes, so that small foods fall greatly. Although it is easy, it is possible to reliably prevent small foods from falling even in a portion where such a large gap is formed.

That is, since the protruding piece 33 provided on the uppermost shelf plate 19 has an inclined surface 33aa that inclines so as to be located upward toward the rear edge, small foods move toward the trailing edge side of the protruding piece 33. In addition, since the inclined surface 33aa is inclined upward, the distance between the trailing edge and the surface of the portion protruding in front of the refrigerating chamber duct 28 is narrowed, so that the small food can be used. You can surely prevent it from falling. As a result, it is possible to obtain a highly reliable refrigerator in which the user does not feel distrust due to the fall of small foods.

Further, the projecting piece 33 provided on the uppermost shelf plate 19 can prevent small foods from falling even if the rear end edge is inclined upward so that the rear end edge does not project to the back wall 14a of the refrigerator compartment. Therefore, the depth dimension of the protruding piece 33 can be made small. In particular, since this part is the part where the refrigerating chamber duct 28 protrudes forward, the dimension up to the refrigerating chamber back wall 14a is longer by the dimension in which the refrigerating chamber duct 28 protrudes, and the refrigerating chamber is in a horizontal state. If it protrudes to the back wall 14a, it becomes large, and the shelf board 19 becomes heavier by that amount, making it difficult to attach and detach it. However, according to the configuration of this embodiment, the weight increase of such a shelf board 19 is minimized. , It can be made easy to put on and take off while preventing small items from falling.

Next, the action and effect of the support of the shelf board 19 will be described.

If each of the above shelf boards 19 becomes dirty, it is removed from the refrigerator compartment 14 and washed with water, but at that time, the refrigerator is installed near the wall of the room and the door 11 cannot be opened more than 90 degrees. Even in such a case, the shelf board 19 can be easily taken out from the refrigerator compartment 14 in this refrigerator.

That is, the shelf board 19 of the refrigerator is pulled out toward the front side while being supported by the support portion 32, and the receiving portion 40 provided in the front portion of the shelf board 19 is positioned in front of the front support portion 34, and FIGS. As shown in (b), when the notch 39a at the rear of the shelf board 19 slides to the point where it matches the front support 34, the notch 39a falls off from the front support 34 and the other as shown in FIG. It is tilted with the front support on the side as a fulcrum. Therefore, even if the door 11 cannot be opened 90 degrees or more and the door pocket 11a is located in the front, the door pocket does not get in the way, and the door pocket is tilted and pulled out to the front side as it is. The shelf board 19 can be easily attached and detached.

The notch 39a at the rear of the shelf board 19 and the front support portion 34 of the side wall of the refrigerating chamber are configured so that the front edge of the shelf board 19 matches at least at a position rearward from the opening edge of the refrigerating chamber 14. Therefore, the shelf board 19 can be tilted without being pulled out from the opening edge of the refrigerator compartment 14 to the front, and the shelf board can be securely attached and detached even if the refrigerator compartment door cannot be opened by 90 degrees or more. be able to.

Further, since the shelf board 19 is provided with a convex portion 39b that fits into the recess 36 of the support portion 32 when the shelf board is set, the shelf board 19 is slightly lifted when the shelf board is taken out, and the convex portion 39b is moved into the recess 36. It is necessary to remove it from and pull it out to the front side. That is, the shelf board 19 cannot be slid unless the convex portion 39b and the recess 36 are disengaged, that is, the shelf board 19 is not intended to be removed by lifting the shelf board 19 upward before sliding it toward the front side. The shelf board 19 can be prevented from being inadvertently slid forward to prevent the shelf board 19 from falling off from the front support portion 34 and becoming an inclined state, and safety can be improved.

Further, since the receiving portions 40 provided on both front side portions of the shelf plate 19 are provided with concave grooves 41 having a substantially U-shaped cross section for gripping the front support portion 34 and fitted to the front support portion 34. Careless vertical movement of the shelf board 19 can be prevented, and the shelf board 19 can be reliably fixed and supported.

In addition, each of the shelf boards 19 is placed on a support portion 32 provided in the refrigerating chamber 14, and the rear portion of the shelf board 19 is placed on a lower support surface portion 35a provided in the rear support portion 35. Since it is placed, the upper surface thereof is substantially the same as the upper surface portion 35b of the rear support portion 35, and the notch portion on the rear side portion of the shelf plate becomes concave so that small foods can be fitted into the portion. Things can be prevented and reliability can be improved.

Next, the operation and effect of the lighting device 30 provided in the refrigerator compartment 14 will be described.

Therefore, the flow of the foamed heat insulating material 4 when the foamed heat insulating material is filled. It is possible to suppress such things as inhibiting.

That is, since the side wall light source units 44 are individually and separately provided, it is possible to secure a space in which the foamed heat insulating material 4 flows between the side wall light source units 44. As a result, the foamed heat insulating material 4 can flow between the side wall light source units 44 and flow to the side wall front end edge of the refrigerating chamber 14 reliably and smoothly, and can exhibit good heat insulating performance. Therefore, while installing the lighting device 30 on the side wall of the refrigerator main body 1, the side wall can be thinned to increase the internal capacity. That is, it is possible to make a refrigerator having a large capacity and high visibility as it is.

Further, each side wall light source unit 44 on the side wall of the refrigerating chamber includes a light source substrate 46 having a light source 45 and a substrate holding case 47 holding the light source substrate 46, and each substrate holding case 47 connects a substrate holding portion 47a. Since the connecting rail 47b is connected and integrated by the crosspiece 47b and has a bridge shape that forms a space 49 for the flow of the foamed heat insulating material, the workability of installing the light source unit is improved and the side wall is thinned. It is possible to achieve both installation of a lighting device and thinning of the side wall.

That is, each side wall light source unit 44 is held by the substrate holding case 47 and becomes an integral body, and each side wall light source unit 44 can be attached by simply attaching the substrate holding case 47, and workability is improved. Moreover, since the connecting rail 47b of the substrate holding case 47 that integrates the side wall light source unit 44 has a bridge shape and forms a space 49 for the flow of the foamed heat insulating material, the foamed heat insulating material 4 passes through this space 49. It is possible to smoothly flow to the front end edge of the side wall of the refrigerating chamber, and even if the side wall is thin, the heat insulating property of the front end portion of the side wall can be improved. Therefore, it is possible to improve the workability of installing the light source unit and at the same time realize the thinning of the side wall, and to achieve both the installation of the lighting device and the thinning of the side wall.

Further, in this embodiment, each side wall light source unit 44 provided on the side wall of the refrigerating chamber is provided independently between the shelf boards 19 of the second and third stages and the third and fourth stages from the top. The inside of the refrigerating chamber 14 in the middle to lower part where light is hard to reach from the top surface light source unit 43 on the top surface of the refrigerating chamber can be brightened, and the visibility of the refrigerating chamber can be improved.

In addition, since each side wall light source unit 44 of the side wall of the refrigerating chamber provided between the shelf boards 19 is provided above the center in the height direction between the shelf boards, the space between the shelf boards 19 is irradiated from above. Even if a relatively tall food is placed on the front portion of each shelf board 19, the food placed in the back can be reliably irradiated, and the visibility can be greatly improved.

On the other hand, since the top surface light source unit 43 provided on the top surface of the refrigerating chamber 14 is provided so that the top surface light source 43a is located in front of the front end edge of the uppermost shelf plate 19a, it is in front of the front end edge of the shelf plate. Therefore, the inside of the refrigerating chamber 14 can be efficiently irradiated, and the visibility inside the refrigerating chamber 14 can be further improved.

Moreover, in this embodiment, since the top surface light source cover 43d of the top surface light source unit 43 is positioned so as to overlap the front end edge of the uppermost shelf plate 19, the light of the top surface light source 43a is directed to the top surface light source. The cover 43d can diffuse and irradiate the entire upper part of the refrigerating chamber 14, and the visibility can be improved.
