[0019]
The freezer compartment 18 used as a frozen food storage container is composed of a metal plate 20 composed of a bent bottom wall 24 and side walls 23 and 25 on both sides thereof, and between the two side walls 23 and 25 of the metal plate 20. Two synthetic resin members 30 that close the two opened side surfaces are combined. In this way, by closing the open side of the metal plate 20 with the synthetic resin member 30, the bottom wall 24 and both side walls 23, 25 can be formed by bending a single metal plate, which is extremely easy to manufacture. can do. Further, since the synthetic resin member 30 is composed of two members, the injection mold can be made small and inexpensive. Note that the synthetic resin member 30 may be formed as a single member as necessary. In this case, the mold becomes large, but the assemblability with the freezer compartment 18 is improved.
[0020]
The metal plate 20 is formed of a metal plate having good thermal conductivity and high safety for food stored in the refrigerator, such as a stainless steel plate or an aluminum plate. The metal plate 20 is formed in a substantially U shape by a bottom wall 24 on which stored foods are placed and two side walls 23 and 25 that extend upward from the front and rear ends of the bottom wall 24 and face each other. Since the food in the freezer compartment 18 is cooled not only by the bottom wall 24 but also by the side walls 23 and 25, even if it is stored throughout the freezer container 18 (in other words, stored in a large amount). Frozen quickly. Since the side walls 23 and 25 are formed so as to substantially coincide with the flow direction of the cold air discharged from the cold air discharge port 14, the both side walls 23 and 25 are rapidly cooled by the flow of the cold air.
[0021]
The front side wall 23 and the back side wall 25 are formed in parallel. In other words, the distance between the front side wall 23 and the back side wall 25 is such that the bottom dimension L1 and the top dimension L4 are substantially the same, and no draft N1 or N2 is provided as shown in FIG. It is said. Thereby, compared with the prior art 2, a foodstuff can be accommodated widely to the bottom part.
[0022]
The metal plate 20 and the synthetic resin member 30 have a difference in horizontal expansion and contraction due to thermal expansion of the bottom wall 24 of the metal plate 20 and a difference in vertical expansion and contraction due to thermal expansion of the side walls 23 and 25 of the metal plate 20. It is constructed and combined so that it can be absorbed.
[0023]
On the upper surface of the front side wall 23, a substantially horizontal front flange 22 having flexibility so as to absorb a difference in expansion and contraction due to thermal expansion is formed. That is, when the height of the front side wall 23 shown in FIG. 3 and the height of the holding rib 32 of the synthetic resin member 30 corresponding to the front side wall 23 are set to the dimension H1, the front flange 22 is synthesized with the change in the ambient temperature. The structure is flexible enough to absorb the difference δ1 between the amount of expansion / contraction of the resin holding rib 32 and the amount of expansion / contraction of the metal front side wall 23. A front hanging flange 21 is provided on the front surface of the front flange 22. The front hanging flange 21 is provided with a hole 21a for locking the locking portion 31a of the synthetic resin member 30.

On the upper surface of the back side wall 25, a substantially horizontal back flange 26 is provided which has flexibility so as to absorb a difference in expansion and contraction due to thermal expansion. That is, when the height of the back side wall 25 and the height of the holding rib 35 of the synthetic resin member 30 corresponding to the back side wall 25 shown in FIG. The structure is flexible enough to absorb the difference δ2 between the expansion / contraction amount of the holding rib 35 and the expansion / contraction amount of the metal back side wall 25. In addition, a rear hanging flange 27 is provided on the rear surface of the rear flange 26. A hole 27a is provided in the bottom flange 27 so as to be locked by a locking tool 28 such as a screw or a thumbscrew to which the synthetic resin member 30 can be attached and removed.
[0025]
Moreover, the metal plate 20 has a plurality of holes 22a, 23a, 25a, and 26a for circulating cold air that cools the stored food. Thereby, when the cold air cooled by the cooler 10 is discharged from the cold air discharge port 14 to cool the stored food, the stored food side of the metal plate 20 is cooled so that the freezing time of the stored food can be shortened. At the same time, the back side of the metal plate 20 in contact with the stored food can be cooled at the same time.
[0026]
The holes 22a and 26a for circulating the cold air are provided in the front flange 22 and the back flange 26. In addition to the effect of cooling the front and back of the metal plate 20 at the same time, the front flange 22 and the back flange 26 are heated.

[0027]
The synthetic resin member 30 constitutes a right side surface and a left side surface that require a more complicated shape among the side surfaces constituting the freezer compartment container 18, and is combined so as to sandwich the metal plate 20. Yes. In other words, the synthetic resin member 30 having the holding flange 36 having a complicated shape that engages with the frame body 41 of the door 8 is formed of a synthetic resin member that can be injection-molded.
[0028]
Since the synthetic resin members 30 on both sides have a similar shape, the same reference numerals are given, and the following description will be made by taking one synthetic resin member 30 as an example.
[0029]
The synthetic resin member 30 has a front side wall holding rib 32, a bottom wall holding rib 33 and a back side wall holding rib 35. The front side wall holding rib 32, the bottom wall holding rib 33 and the back side wall holding rib 35 are provided inside the synthetic resin member 30 so as to hold the ends of the front side wall 23, the bottom wall 24 and the back side wall 25 of the metal plate 20.

The bottom wall holding rib 33 is formed on the bottom wall 24 as shown in FIGS. Placement It is provided so as to be in close contact with the back surface of the bottom wall 24 so that the bottom wall 24 itself is not deformed by the load of the stored stored food. That is, in FIG. 3, a gap is provided between the bottom wall holding rib 33 and the back surface of the bottom wall 24, but the gap δ0 is zero.
[0031]
The front side wall holding rib 32 is provided so as to have a gap δ3 between the front side wall 23 of the metal plate. The front side wall holding rib 32 is provided with locking portions 32a and 32b so that the front side wall 23 can be held by the holes 23b and 23c. By inserting the locking portions 32a and 32b into the holes 23b and 23c of the front side wall 23, the movement of the front side wall 23 in the vertical and horizontal directions is restricted and held.
[0032]
The back side wall holding rib 35 is provided so as to have a gap δ 4 described later between the back side wall 25 of the metal plate 20. A screw portion 29 for locking the metal plate 20 with a plurality of locking tools 28 is provided on the upper portion of the rear side wall holding rib 35.
[0033]
Here, the gaps Δ3 and Δ4 will be described. The size of the metal plate 20 and the synthetic resin member 30 expands and contracts due to changes in ambient temperature, and the size of the expansion and contraction varies depending on the type of material. If the construction prevents the expansion and contraction, an internal stress is generated corresponding to the flexure to be expanded and contracted and the structure is internally destroyed. In order to prevent this, in this embodiment, the internal stress is not generated in the components of each part of the container. That is, as shown in FIG. 3, the length of the metal bottom wall 24 is L1, the length of the synthetic resin member 30 is L2, and the difference in expansion / contraction when the ambient temperature is changed is δ6. Then, the configuration is such that δ6 <δ3 + δ4. Normally, δ3 = δ4 is set, but δ3 (inequality) δ4 may be used for convenience in use and molding. The gaps δ3 and δ4 described above preferably include a dimensional accuracy error in manufacturing the metal plate 20 and the synthetic resin member 30 itself and a necessary gap in assembly.
[0034]
The auxiliary holding rib 34 holds the back side wall 25 of the metal plate 20. The auxiliary holding rib 34 has locking portions 34a and 34b so that the back side wall 25 of the metal plate 20 can be held by the holes 25b and 25c.
[0035]
The hanging flange holding rib 31 provided on the synthetic resin member 30 is provided with a locking portion 31 a for locking the front hanging flange 21 of the metal plate 20. Note that a gap δ5 is provided between the hole 21a provided in the front hanging flange 21 and the above-described locking portion 31a so as to assist in absorbing a difference in expansion and contraction due to thermal expansion described later. Has been.
[0036]
The holding flange 36 is configured so that the load of the container 18 itself and the load of stored food can be held on the frame body 41 installed on the door 8. The frame body 41 is provided in a substantially U shape (viewed from the plane) from the back surface of the door 8. The frame body 41 is provided with a roller 41 a for lubricating the opening / closing operation of the door 8.
[0037]
Here, when a stainless steel plate is used as the raw material of the metal plate 20 and a polystyrene resin is used as the raw material of the synthetic resin member 30, specific examples of expansion and contraction of each part due to a change in ambient temperature will be described. However, for the sake of explanation, it is assumed that there is no dimensional accuracy error in the manufacturing process. It is assumed that the thermal expansion coefficient of the stainless steel plate is 0.000011 and the thermal expansion coefficient of the polystyrene resin is 0.000070. As the assumption of the ambient temperature change, the ambient temperature at the time of container manufacture is set to 30 ° C., or the ambient temperature for cleaning the container taken out of the refrigerator in the summer is set to 30 ° C., and the temperature after being incorporated in the refrigerator is minus 20 If it is C, the temperature change is 50C.
[0038]
In the above assumption, when the L2 dimension shown in FIG. 3 is set to 500 mm and the H1 dimension is set to 300 mm, the dimensional expansion / contraction difference between the metal plate 20 and the synthetic resin member 30 at a temperature change of 50 ° C. is about 1 in the L2 dimension part. .5mm, H1 dimension is about 0.9mm. Therefore, in the dimension H1, the difference in expansion / contraction due to thermal expansion between the metal front side wall 23 and the synthetic resin member 30 is about 0.9 mm, so the front flange 22 itself is flexible so as to satisfy δ1> 0.9 mm. Therefore, the occurrence of internal stress in each part can be prevented. In the L2 dimension portion, the expansion / contraction difference due to thermal expansion between the metal bottom wall 24 and the synthetic resin member 30 is about 1.5 mm. Therefore, the dimension including the gaps δ3 and δ4 is about 1.5 mm or more. If so, the occurrence of internal stress in each part can be prevented.
[0039]

However, the ice making device escape portion 67 may be provided only on the rear side plate 60B.
[0045]
The holding ribs 64 of the front side plate 60A and the rear side plate 60B are provided with recesses 64a. By fitting bent portions 53b provided before and after the bottom wall portion 53a into the concave portions 64a, the metal plate 50 and the synthetic resin member 30 are more securely clamped. The rear plate 60B is provided with holding ribs 62, 63, 64, and 65, and the same effects as those of the holding ribs 32, 33, and 35 described above are produced.
[0046]
Flange holding ribs 61 and 66 each having a hole 66a are provided at both left and right ends of the rear plate 60B. The flange holding ribs 61 and 66 are installed on the frame body 71 of the door 7 together with the flanges 51 and 55 of the metal plate 50. Further, the flange holding ribs 61 and 66 are detachably installed on the frame body 71 by means of attachment or detachable screws or thumbscrews. Therefore, the ice making chamber container 48 can be easily removed from the frame 71 by removing the locking tool 69. Further, after the ice making chamber container 48 is removed from the frame 71, the bent portion 53b provided on the front and back of the bottom wall portion 53a and the concave portion 64a of the side plate are disengaged, whereby the ice making chamber container 48 is a component thereof.

Next, a plurality of modifications of the metal plate 20 constituting the freezer compartment container 18 will be described with reference to FIG. 8 is the same as FIG. frozen It is a figure which shows the modification of the metal plate of a chamber container. 8A and 8B are a perspective view and a EE cross-sectional view of the metal plate of the first modification, and FIGS. 8C and 8D are a perspective view and F- of the metal plate of the second modification. FIGS. 8E and 8F are a perspective view and a GG cross-sectional view of the metal plate of the third modification, and FIGS. 8G and 8H are perspective views of the metal plate of the fourth modification. FIGS. 8A and 8B are a perspective view and a PP cross-sectional view of a metal plate of Modification 5. FIGS.
[0048]
In the first modification, a recess 81 a is provided across the front side wall 23, the bottom wall 24, and the rear side wall 25 of the metal plate 20. A plurality of hollow ribs 81a are formed in the left-right direction. The recess depth T2 and the recess width W1 of the recess rib 81a are set according to the food load stored in the metal plate 20, the raw material thickness T1 of the metal plate 20, the rigidity strength of the metal material, and the like. Further, by increasing the depth T2 of the hollow rib 81a, the strength of the metal plate 20 can be increased to reduce the thickness T1, and the amount of cool air passing through the hollow can be increased. It can promote the cooling of food.
[0049]
In the second modification, the thickness T1 of the metal plate 20 is thick to some extent, and the bottom wall 24 can withstand the load of the food load stored in the metal plate 20 to some extent, and straddles the bottom wall 24 and the side walls 23 and 25. A plurality of hook-shaped ribs 82b are provided only in the portion.

In the third modification, only the bottom wall portion 24 made of metal is provided with a plurality of rib-shaped ribs 83a, which is used when an intermediate plate thickness between the first and second modifications is employed.
[0051]
In the modified example 4, the metal bottom wall 24 is provided with a stepped diaphragm 84a, and the bottom wall 24 is reinforced while improving the cleanability of the bottom surface of the container.
[0052]
In the fifth modification, a plurality of hook-shaped ribs 85 a are installed only on the metal bottom wall 24, and are installed substantially in parallel with the front side wall 23 or the back side wall 25. Therefore, since the tip of the flange-shaped rib 85a is held by the synthetic resin member 30, it is possible to achieve a configuration in which the strength improvement with respect to the load of the metal bottom wall portion becomes more remarkable. Further, since a relatively concave portion 85b is formed between the plurality of bowl-shaped ribs 85a, an effect of increasing the cooling speed of the stored food is produced by the flow of cold air through the concave portion 85b.
[0053]
Some effects of the above-described embodiment are described together with the configuration as follows.
[0054]
The freezer compartment 18 includes a single metal plate 20 forming a bottom wall 24 and two opposing side walls 23 and 25 in contact with the bottom wall 24, and a synthetic resin member 30 in contact with the metal plate 20. Because the upper surface is opened, the stored food is cooled from above and below. In addition, since the freezer compartment 18 has three metal surfaces, the additionally stored food can easily come into contact with the metal surface, and the food can be cooled in a short time. A draft is not necessary, and the thickness of the metal plate 20 can be made thinner than that of a conventional synthetic resin container, so that a refrigerator with a large food storage space can be obtained. Furthermore, since the mold for forming the metal plate 20 can be formed by a general bending mold, a refrigerator that is advantageous in terms of manufacturing cost as compared with the drawing mold can be obtained.
[0055]
Since the two side walls 23 and 25 of the metal plate 20 of the freezer compartment 18 are the back side wall and the front side wall, and the metal plate 20 with good thermal conductivity is disposed in the direction of the cold air circulation, the stored food is placed on both the upper and lower sides. Therefore, the refrigerator can be cooled in a short time.

It is made of metal with a small coefficient and is tilted to the extent that the ice that has fallen on the bottom wall 53a slides, so that the effective use of the internal volume of the container is possible without accumulating only where the ice is made. It can be set as the refrigerator which can do.
[0057]
The substantially horizontal flanges 22 and 26 are provided on the metal side walls 23 and 25 connected to the metal bottom wall 24. Due to the flexibility of the flanges 22 and 26, the metal side walls 23 and 25 and the synthetic resin member 50 are connected to each other. Since the difference in expansion and contraction due to thermal expansion is absorbed, it is possible to provide a structurally reliable refrigerator that does not generate internal stress even in an environment where the ambient temperature changes.
[0058]
A flange 26 is provided on the side wall 25 of the substantially U-shaped metal plate 20, and a screw or a wing screw that can be attached to and detached from the substantially U-shaped metal plate 20 and the synthetic resin member 30 using the flange 26.

The refrigerator can be easily washed even in a small place.
[0059]
Since the recessed rib 81a or the hook-shaped rib 82b is provided at a position straddling the metal bottom wall 24 or the metal bottom wall surface 24 and the metal side wall surfaces 23, 25, the metal bottom wall 24 is made of a thin metal.
