BACKGROUND OF THE INVENTION
The present invention relates to a refrigerator.
[0002]
[Prior art]
A conventional refrigerator will be described with reference to FIGS.
As a means for fixing the accessory storage container 109 to the door inner plate 108 of the conventional refrigerator, a hole 108 a for hooking the accessory storage container 109 is opened in the door inner plate 108 in advance, and the door outer plate 107 a and the door inner plate 108 are opened. In order to prevent the pseudo piece 113 from moving, the pseudo piece 113 corresponding to the shape of the collar of the small article storage container 109 is inserted into the hole 108a and the movement preventing piece 114 is packed, Cover the dummy piece 113 and the movement prevention piece 114 with the soft film 115 or the like from the back side (urethane side) and carefully attach the periphery of the soft film 115 to the door inner plate 108 so that the urethane foam does not leak out. It was mounted on urethane foam foaming staff 117 and foamed urethane foam. In addition, in the space part in which the collar part of an accessory storage container enters, there was a possibility that the heat insulating material of a door might become thin and condensation might occur.
[0003]
However, since this method is troublesome to set the dummy piece and the movement preventing piece, as shown in FIG. 12, the door inner plate 108, which has been separately molded into the refrigerator door after urethane foaming on the door outer plate 107a, is replaced with a small container. There is a method in which a space 116 in which 109 collars 109 a are accommodated is opened and covered, and then the periphery of the door inner plate 108 is fixed to the door outer plate 107 a with screws 118.
[0004]
However, in these methods, if the door inner plate 108 is thin and a heavy article enters the small article storage container 109, the surroundings of the hole 108a may crack due to repeated loads due to an impact at the time of opening and closing the door, Since it may be torn, the reinforcing plate 111 had to be stuck on the urethane foam side as shown in FIG. However, if the reinforcing plate 111 is applied, the load is transmitted to the outer periphery of the inner plate due to reinforcement, and the tightening portion 108b of the screw 119 fixing the door inner plate 108 to the door outer plate 107a is cracked or torn. There was a phenomenon.
[0005]
Next, the attachment form of the conventional accessory storage container is demonstrated. As shown in FIG. 13, holes 108a and 108b are formed in the door inner plate 108 at opposite portions of the flanges 109a and 109b provided on the back surface 109c of the small article storage container 109, and the suspended rods are inserted into the engagement holes. The accessory storage container 109 is attached by being shifted downward, but since the flanges 109a and 109b of the accessory storage container 109 are only at two positions on the upper side, the weight of the storage object in the accessory storage container 109 is reduced when the door is opened and closed. Since the collar moves as a fulcrum of rotation due to the reaction of closing and opening the door, cracks may occur in the roots 109a 'and 109b' of the collar due to repeated loads, and depending on the small article storage container 109, it may fall There was a fear. FIG. 14 is a cross-sectional view of a main part showing a state in which the small article storage container 109 is engaged with the door inner plate 108. As shown in FIG. Since it is above the storage container 109, the hook 109 a of the small storage container 109 is inserted into the hole 108 a of the door inner plate 108, and the hook of the small storage container 109 is not clogged after being hooked. Since a part of the eaves insertion hole 108a can be seen from the outside in the upper door inner plate 108, it looks bad and there is a risk that food scraps near the storage shelf may enter.
[0006]
In addition, when the accessory storage container is formed of a transparent material, the bases 109 'and 109b' of the heel can be seen through from the table, so that the appearance is poor.

[Problems to be solved by the invention]
In order to create a clean appearance without attaching a rail for a hook metal fitting such as a cantilever, after fixing the door inner plate to the door outer plate and then foaming urethane foam, the door inner plate It is necessary to leave only the part in which the heel is inserted in the hole for hanging the small container, and temporarily attach a heel pseudo piece corresponding to the size of the heel before foaming the urethane foam. In addition, it is necessary to create a space that can be removed after the urethane foam is foamed, and in order to fix it so that it does not move during the foaming operation, a movement prevention piece is inserted, and then urethane It is necessary to cover the foam with a soft film to prevent the foam from adhering to it, and there is a problem that it takes a lot of work to install and remove before and after the foaming work. Liquid is to prevent the leaking from the gap hook housing space, there are problems such as sticking carefully.
[0009]
Furthermore, in the space part in which the collar part of the small article storage container enters, there is a possibility that the heat insulating material of the door becomes thin and dew condensation occurs.
[0010]
Therefore, the first purpose is to insert the dummy pad and anti-moving piece before foaming and stick the soft film on it to make the space for inserting the bag, and the hook part of the small container It is to provide a refrigerator that does not cause condensation.
[0011]
In addition, the conventional method of fixing the storage container to the inner plate of the door is a process in which urethane foam is foamed only on the door outer plate in advance. The joint member was inserted and fixed from the heat insulating material side, and was able to be fixed by hooking the hook of the storage container from the hole at the tip of the bank of the inner plate of the door in a later process. Therefore, when foaming to the door, it is necessary to stick a film to prevent the urethane foam from sticking to the mold surface that molds the heat insulating material side, and the door inner plate is attached to the foamed door body. When installed, the periphery of the door inner plate was fixed with screws, etc., so the door inner plate was repeatedly loaded around the screws due to the weight of food in the storage container and the vibration of the door opening and closing. There was a problem that it was easy to enter and was damaged. Accordingly, a second and third object of the present invention is to provide a refrigerator in which a film for preventing urethane adhesion is removed and a load of food is hardly applied to a screw tightening portion of a door inner plate.
[0012]
In addition, when the door is opened and closed, moisture in the air condenses around the hole, forming water droplets that accumulate in the lower part of the hole, and the water droplets may rot and give off a bad odor over a long period of time. It is necessary not to accumulate.
[0013]
In order to attach the accessory storage container to the door inner plate, it is attached by engaging the flange on the back of the accessory storage container with the hole provided in the door inner plate, but the accessory storage container is only on the upper side. Therefore, when the door is opened and closed, the collar moves as a fulcrum of the small container due to the weight of the small container and the reaction when the door is opened and closed. In some cases, some containers may fall. Accordingly, a fourth object of the present invention is to prevent back-and-forth swinging by providing two stages of left and right upper and lower ridges of the small container, and the remaining remains even if one full heel is damaged. Is to provide a safe refrigerator.
[0014]
In addition, if the small container is molded with a transparent synthetic resin material, the root can be seen through from the surface on the opposite side (front side) where the base of the hanging hook is, so it looks bad. Must be inconspicuous. The fifth object of the present invention is to make the root of the accessory storage container inconspicuous from the front side.
[0015]
In addition, since the hook for mounting on the back side of the small container is near the upper end of the small container, the hook of the small container is inserted into the mounting hole of the door inner plate and suspended, and then the suspended mounting hole is covered. However, since it was visible from the outside, there was a problem that it did not look good and food waste etc. were easy to enter. Then, it is providing the refrigerator which can block | close a mounting hole easily.
[0016]

【The invention's effect】
As described above in detail, according to the present invention, since the door inner plate and the door outer plate in which the reinforcing small box is incorporated are integrally processed with urethane foam, the load of the small container is applied to the door inner plate. However, since it is received by the reinforcing plate of the reinforcing small box and the entire inner plate of the door, the load is dispersed and the force applied to the fixing screw portion of the door inner plate becomes weak, and a refrigerator with less damage to the screw portion can be provided. .
[0032]
Since a small box with a lid for storing the buttock of a small container is installed on the heat insulating material side of the door inner plate, there is no need for a dummy piece or movement prevention piece before urethane foaming, and no urethane leak prevention sheet, etc. Thus, a refrigerator with high production efficiency can be provided.
[0033]
Since a plurality of reinforcing plates with ribs are molded integrally with the reinforcing small box, it is in close contact with the urethane foam and has a high strength mounting structure, and the inner plate is less likely to be damaged by the load of the small container.
[0034]
Even if water droplets adhere to the hole of the reinforcing small box by opening and closing the door, water flows from the drain hole provided in the lowermost part to the inside of the warehouse, so it does not accumulate and does not rot and give off odor.
[0035]
As the small container storage box is provided on the top, bottom, left and right, the front and back are not shaken by the impact when the door is opened and closed, and the repeated load on the hook is no longer applied. Can be provided.
[0036]
When a small container is made of a transparent material and a mounting collar is provided on the back, diamond cuts and hairlines are applied to the surface of the collar, making the base of the collar difficult to see due to irregular reflections A good refrigerator can be provided.
[0037]
Since the back plate of the small storage container covers the buttock insertion hole of the small storage container provided in the reinforcing small box installed on the inner plate of the door, the hole can be seen from the outside after the small storage container is assembled. Since it does not exist, it can provide a nice-looking refrigerator.
