Description

Door of food storage

The present invention relates to a door of a food storage for storing food in a fresh state. The food storage includes not only a refrigerator but also a device capable of ripening food and storing it for a long time. In particular, the present invention relates to a kimchi maturation and storage door of the kimchi to mechanically mature kimchi and to store the mature kimchi in a refrigerated state, in particular to stabilize the foaming process to prevent the deformation of the door and to enhance the appearance of the door It relates to kimchi ripening and the door structure of the storage.

There are many types of food storage, including refrigerators, but for convenience of explanation, we will describe using kimchi ripening and storage as an example. Figure 1 is a side cross-sectional view showing the overall configuration of the conventional kimchi ripening and storage, the kimchi ripening and storage 10 is opened and closed in the vertical direction by the main body 11 and the hinge 12 made of a substantially rectangular enclosure shape. (13). The main body 11 is divided into an upper compartment 16 and a lower compartment 16 by the baffle plate 14. The upper compartment 15 is formed with a storage compartment 17 for storing food such as kimchi, and a condenser 18 is disposed along the inner circumferential wall of the upper compartment 15. The evaporator 19 is disposed along the outer circumferential wall of the storage chamber 17, and the condenser 18 and the evaporator 19 are connected to each other. The heater 20 is arranged in the form of a hot wire on the bottom of the storage compartment 17, and the insulation 21 is filled between the upper portion of the baffle plate 14, the upper compartment 15, and the storage compartment 17. The lower compartment 16 is provided with devices such as a compressor 22 and electrical equipment. The door 13 is also filled with a heat insulator 24 therein. Kimchi ripening and storage 10 is controlled by a control unit (not shown) (for example, to select an operation mode, such as kimchi ripening selection or kimchi storage selection) installed in a suitable place of the body 11 or the door 13 .

The kimchi ripening and storage must be maintained at a predetermined ripening temperature or storage temperature without changing the temperature in the storage chamber 17 in order to store the kimchi is aged, as well as the maturation is completed.

The temperature change in the storage compartment 17 is also affected by how the cooling system and the heaters are controlled, but also by the cold air leakage from the storage compartment, which is closely related to the sealing of the door. .

The structure of the door has been developed and used in various ways to maintain the sealing degree of the door. Such a door is composed of an outer plate forming an outer surface and an inner plate forming an inner side, and the outer plate and the inner plate are joined together, and a foam material is filled between these outer and inner plate members.

However, in order to maintain and reinforce the installation interval of the outer plate and the inner plate of the door, the boss is necessarily installed at a suitable position between their inner and outer plate. Such bosses are usually injection-molded integrally with the inner circumferential wall of the outer plate, and thus shrinkage occurs inward from the root portion of the boss integrally injection-molded with the inner circumferential wall of the outer plate so that the surface of the outer plate is partially immersed. It will reduce the appearance of the back door.

In addition, the foaming process of the foaming material filled for insulation between the outer surface and the inner surface of the foam is usually formed by placing the door in a horizontal state, and foaming in such a state that the foaming material does not spread uniformly in the inner space. There is a drawback to this. This non-uniform diffusion prevents the foaming material from filling the interior space of the door faithfully and uniformly, and furthermore, undesired gas exhaust occurs during foaming, causing unmolding or post-foaming to cause deformation.

In addition, a separate inlet is installed at the proper position of the inner and outer plates forming the door for the injecting of the foam material.The inlet is a factor that hinders the appearance of the finished door as it is not easily processed after the completion of foam molding. It is becoming.

An object of the present invention is to provide a door for use in a food storage that can improve the thermal insulation effect by making the insulation of the foam material formed inside the door uniformly and evenly filled in the door.

Still another object of the present invention is to provide a door for use in a food storage that can easily combine the outer member and the inner member constituting the door, and can easily perform the foam molding operation.

Still another object of the present invention is to provide a door for use in a food storage having a beautiful appearance.

The door for use in the food storage according to the present invention is an outer member having one side is opened and has a depression recessed by a predetermined distance along the outer peripheral surface; An inner member having one side open and having a depression recessed by a predetermined distance along an outer circumferential surface thereof; A plurality of bosses for reinforcing the inner and outer members, the predetermined spaces being formed along the inner circumferential surface of the inner member to form a predetermined space between the inner and outer members while the outer member and the inner member are coupled; A heat insulating material filled between the spaces formed between the inner and outer members; An inlet formed in the inner member for injecting a foamable material for forming the insulation; And an exhaust port for discharging the gas generated when the foaming material for forming the heat insulating material is formed in the space formed between the inner and outer members and air present in the space to the outside. It includes.

Hereinafter, with reference to the accompanying drawings, the present invention that can be applied to the doors of various types of food storage. As mentioned above, kimchi ripening and storage devices are described as examples for convenience of explanation. 2 shows a plan view of the door according to the present invention, in which the body of the door 100 is shown with reference to the inner side. The door 100 includes an outer member 110 and an inner member 120. The outer member 110 and the inner member 120 are made of metal or synthetic resin, respectively, and have a plate shape. The outer member 110 and the inner member 120 are coupled to each other to form the overall shape of the door 100. The inner member 120 of the door 100 configured as described above is provided with an accommodating part 121 in which a deodorant is stored at a position biased to one side from the center of the inner member 120. The auxiliary material 124 is attached to the inner member 120 to improve the appearance.

Figure 3 shows a cross-sectional view showing the overall configuration of the door of the present invention cut along the line A-A of FIG. The door 100 has an outer member 110 and the inner member 120 is combined to maintain the overall shape of the door, the outer member 110 is formed of a hollow rectangular parallelepiped shape with the bottom open to form the outer shape of the door inside The member 120 also has a hollow rectangular parallelepiped shape in which an upper surface thereof is opened to correspond to the shape of the outer member 110 as a whole. That is, each of the outer member 110 and the inner member 120 has a depression that is recessed by a predetermined distance along its outer circumferential surface. The outer member 110 and the inner member 120 to form a space therein by maintaining a constant interval in the combined state, wherein the interval between the outer member 110 and the inner member 120 to maintain the inner member 120 It is determined by the height of the boss 122, which is inserted into the bottom surface integrally with a suitable distance along the edge of the). In addition, by maintaining the gap between the inner and outer members, a foaming space of the foamable material for forming the heat insulating layer 130 of the door will be described later. One side surface of the door 100 is provided with a hinge portion 112 extending from the outer member 110, the hinge portion 112 is received by one end of the hinge 113 is connected to the door of the food storage ( 100) can be opened and closed. Reference numeral 125 is a deodorant.

According to one feature of the present invention, the boss 122, which is essentially installed when the inner and outer members are molded as described above, is provided in the inner member 120 without being installed in the outer member 110 as in the prior art. . This configuration is a problem caused by shrinkage that occurs during injection molding, that is, a phenomenon in which the surface of the outer member of the door is partially immersed by the shrinkage phenomenon occurring at the root of the boss when the boss is integrally molded into the conventional outer member. This will completely eliminate the problem of impairing the appearance of the door.

4 is an enlarged cross-sectional view of part B of FIG. 3 and a fixing part for allowing the inner member 120 to be fitted in a jaw fastening manner for the coupling of the inner member 120 along the main wall of the outer member 110. 111 is provided. The fixing part 111 is formed to have the same thickness as the upper surface width of the boss on the portion where the boss 122 is formed. The fixing part 111 has an upper end of the fixing part 111 to have an inclined surface, and the lower part of the fixing part 111 forms a locking groove 112 in a relationship with the upper end of the boss 122 formed in the inner member to suppress the inner member 120. It is fitted in a fitting manner, and thus the installation state thereof becomes stable and robust, and the inner member is prevented from being separated from the state fitted in the outer member. And, by inclining the upper end of the fixing portion 111 when the inner member 120 is coupled to the outer member 110 can be easily inserted. Particularly, in the related art, in order to foam the heat insulating material 130, a heat insulating material was formed in a state in which an outer member and an inner member were combined using a jig or the like separately, but by providing a fixing part, the foaming operation can be eliminated and simple.

FIG. 5 is an enlarged cross-sectional view of part C of FIG. 3 and illustrates a state in which a housing cover is removed. The accommodating part 121 is formed to accommodate the deodorant at an appropriate position of the inner member 120, and an inlet 124 for injecting the foaming material is provided at the bottom of the accommodating part 121. The inlet 124 is concealed in the housing 121 to be invisible from the outside of the door to improve the appearance of the door. A shielding film 142 is formed on the inner surface of the inner member 120 near the inlet 124, and one end of the shielding film 142 is attached to the inner surface of the inner member 120, and a portion extending from the one end is It is formed to be inclined downward with respect to the inlet to be spaced apart from the inlet 124 by a certain distance. Therefore, the shielding film 142 serves as a one-way check valve. When the liquid foamable material is injected through the inlet 124, the foamable material is foamed to gradually fill the space formed by the outer member 110 and the inner member 120 of the door. As the foaming material fills the inner space of the door, the foaming material is pushed upward to block the inlet 124. Since the inlet 124 is blocked, the foamed material does not leak out through the inlet, thereby eliminating the appearance damage or post-treatment process when the inlet 124 flows out.

Meanwhile, an exhaust port 140 is formed at one end of the inner member 120, and the exhaust port 140 is disposed at an upper side of the inlet 124. Exhaust port 140 facilitates the injection of the foaming material during the foaming process of the foaming material for forming the heat insulating material 130, and the foaming material is easily opened by discharging the air inside when the foaming material is foamed inside the door to the outside It allows you to fill the inside.

In addition, a shielding film 141 serving as a one-way check valve as shown in FIG. 5 is also provided on the inner surface of the inner member 120 where the exhaust port 140 is formed as described above. The shielding film 141 is always open. At the last stage of the foaming process, the shielding film 141 is pressed to shield the exhaust port 140. The shielding films 141 and 142 are made of soft synthetic resin having excellent elasticity. When the exhaust port 140 is formed small, the shielding film 141 for discharging air or gas does not need to be formed.

6 is a view showing a foam molding process using the door of the present invention, the inner member 120 of the door 100 to face upward, as shown in the drawing, the exhaust port 140 is formed in the longitudinal direction of the door The door 100 is positioned to have a predetermined inclination by moving the side upward. Then, the foaming material is introduced through the inlet 124 formed on the bottom surface of the deodorant accommodating part 121 provided in the door 100 positioned with a predetermined slope. And the foamed material injected through the inlet 124 flows smoothly by the inclination of the door 100, the reaction occurs from the left end of the door 100, which is the lowest side as shown in the figure gradually fills to the right Comes up. When the foaming material gradually fills the inner space of the door to reach the shielding film 142 formed near the inlet 124, the shielding film 142 moves upward to block the inlet 124 due to the foaming material. Therefore, the foamed material is prevented from flowing out of the door through the inlet 124. Then, the foamed material is filled up to the other end of the door 100 while pushing upward the shielding film 141 formed near the exhaust port 140 to prevent the foamed material from leaking out of the door. The inlet 124 and the exhaust port 140 are air and foamed materials present in the interior space of the door 100 formed by the outer member 110 and the inner member 120 until the foam material is filled to these parts. Since the gas generated from the outside flows out to facilitate the molding process, and also prevents insufficient unfoaming when such air or gas is not discharged, thereby improving the overall appearance of the door.

In this way, the foam is uniformly formed in the inner space of the door by giving an inclination to the door in the foam molding process for forming the heat insulating material 130 in the door 100, and the gas generated in the foaming process is naturally discharged through the exhaust port 140. By exhausting, even more uniform foaming is achieved. In addition, the use of the shielding films 141 and 142 not only improves the appearance of the door, but also eliminates the post-treatment process after foaming. It also prevents the deformation of the door caused by insufficient foaming of the foamable material.

According to the present invention, the outer surface of the outer member of the door is smooth and clean without scratches, thereby improving the appearance of the door.

In addition, the present invention is coupled to the inner member coupled to the outer member of the door by a jaw clamping method to prevent the inner member from being separated from the outer member.

In addition, in the present invention, since the gas generated during foaming is discharged from the foaming space to the outside through the exhaust port, foaming is uniformly performed, and thus deformation of the door caused by insufficient foaming due to air pressure or gas pressure inside the door. Will be prevented.

As described above, the present invention has been described with reference to the embodiment of the kimchi storage in the food storage, but this is for convenience of description and the present invention is not limited thereto and may be changed within the scope of the claims.
