Accordingly, a cooling unit using a circulation of a coolant or a thermoelectric element, a double boiler using a heater or a thermoelectric element, a sterilizing device for emitting high-temperature steam or heat are installed at required positions between the inner case 200 and the outer case 200 and, also, in the first and the second functional compartments 211 and 221 to store the baby food or products in various ways.
• a sealing member (not shown) made of, e.g., rubber is installed at a joint portion therebetween. Further, as shown in Fig. 2, in order to allow the reinforcement plate 220 to be connected with the groove 214 by using bolts and nuts, securing ribs 223 are formed along the front end portion of the reinforcement plate 220.
• a guide shaped identical to that of the reinforcement plate 220 can be formed at an inner side of the outer case 300.
• the reinforcement plate 220 has supporting portions 224 horizontally extended from its two opposite sides.
• the supporting portions 224 support the side surfaces of the outer case 300, thus preventing a deformation of the outer case 300 due to a load from the outside.
• a sealing member (not shown) made of, e.g., rubber is provided at reinforcement plate 220's portions contacting the main body 210 as well as at the supporting portions 124.
• the reinforcement plate 220 is provided with reinforcement member 222 at its front and rear side to prevent a torsion thereof.
• the main body 210 and the reinforcement plate 220 of the inner case 200 are coupled to each other by fastening them with a number of bolts (designated as "B") and nuts (designated as “N”). Then, the assembly of the inner case 200 is connected to the outer case 300 such that the space formed between the main body 210, the reinforcement plate 220 and the outer case 200 is hermetically sealed. Afterward, a liquid insulating material is filled into this space through an injection opening (not shown) and the injection opening is hermetically closed lest the liquid insulating material leak therethrough.
• the first and the second functional compartments 211 and 221 can be isolated from each other and the leakage of the insulating material can be restrained.
• the reinforcement plate 120 in the U-shape, its front end portion can be firmly fixed on the main body 210, and its two side supporting portions 124 support and reinforce the inner surface of the outer case 300. As a result, a deformation of the outer case 300 due to a load or an impact from the outside can be minimized.
