FIG. 8A is a perspective view illustrating thecabinet chassis 406 of FIG. 5. The structure of thecabinet chassis 406 will be described in detail with reference to FIGS. 5 and 8A. Thecabinet chassis 406 is provided at its front end with abent portion 801 primarily bent outwardly to extend along the front surface of therefrigerator 400, and then secondarily bent toward the rear portion of therefrigerator 400. Thebent portion 801 of thecabinet chassis 406 serves to hide gaps possibly formed between thebuilding wall 40 and thecabinet chassis 406 when therefrigerator 400 is embedded in the space formed in thebuilding wall 40, thereby providing a good appearance. - Referring to FIG. 8B, a cabinet chassis according to another embodiment of the present invention is illustrated. The cabinet chassis of FIG. 8B further has a
support rim 802 to support the front surface edge of the integratedinner case 405 in a state in which the frame of the wall-embedded refrigerator is completely assembled, thereby preventing the front surface edge of the integratedinner case 405 from being protruded. - The detailed configuration of the refrigerator frame according to FIG. 5 will now be described with reference to FIG. 9, which is an enlarged view corresponding to a portion “III” of FIG. 5.
- The front surface section405C of the
inner case 405 and theextension 601 of theouter case 404 are uniformly spaced apart from each other by a distance B (FIG. 5). This space receiveshot pipes 901 to prevent a dewing phenomenon from occurring at the front end of the wall-embeddedrefrigerator 400, andmagnets 902 to magnetically couple the magnet-attached doors of the wall-embeddedrefrigerator 400 to the front surface section 405C of theinner case 405. Theextension 601 of theouter case 404 serves to support thehot pipes 901 andmagnets 902 such that thehot pipes 901 andmagnets 902 are in dose contact with the front surface section 405C of theinner case 405.Seal members 903 are disposed in the space defined by the distance B in order to sealably isolate thehot pipes 901 andmagnets 902 from the freezing chamber surface section 405A or refrigerating chamber surface section 406B of theinner case 405, thereby preventing urethane from being leaked from the space when the urethane is foamed in the space. Thecabinet chassis 406 is fixed to theouter case 404 by means of setscrews 904. - Referring to FIG. 5, it can be seen that a partition wall C is formed by the freezing chamber surface section405A refrigerating chamber surface section 405B, and front surface section 405C. As shown in FIG. 5, two
hot pipes 901 and onemagnet 902 are provided at the partition wall C so that they are in close contact with the front surface section 405C. In order to make thehot pipes 901 andmagnet 902 be in dose contact with the front surface section 405C, asupport member 407 is arranged in the space defined by the partition wall C while being fixedly mounted to theouter case 404. - The process of assembling the frame of the wall-embedded
refrigerator 400 having the above described configuration is carried out as follows: - (1)
Hot pipes 901,magnets 902, andseal members 903 are installed at theextension 601 of theouter case 404 and thesupport member 407 is fixedly mounted to theouter case 404; - (2) The integral
inner case 405 is fitted in theouter case 404, and urethane is foamed in a space defined between theouter case 404 and theinner case 405; and - (3) The
cabinet chassis 406 is fixedly mounted to theouter case 404 by means of set screws after completion of the foaming. - As is apparent from the above description, the frame of the wall-embedded refrigerator according to the present invention provides a superior appearance in that there is no step or gap formed by the inner case, and that the cabinet chassis is used to finish the frame. In addition, loss of cold air is reduced, thereby reducing the consumption of electric power. Since the inner case according to the present invention has an integrated structure, it is possible to achieve an improvement in assembling workability and productivity and a reduction in manufacturing costs.
- Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
