Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a so-called built-in refrigerator body that is installed in the wall of a building or between furniture.

(b) Conventional technology There is a built-in refrigerator in Utility Model Application No. 100161/1986, but according to this, a hard foam insulation material is attached to the outer periphery of the inner box, and approximately 100% of the insulation material is attached to the outer surface of the insulation material around the front opening. A U-shaped metal reinforcing plate is bound and covered, and a metal decorative frame having an outwardly extending flange and pivotally supporting the door is attached to this reinforcing plate. The outer surface of the heat insulating material is covered with a non-metallic hard plate. This allows the metal decorative frame to cover the gap between the furniture, etc. and the refrigerator body.

(c) Problems to be solved by the invention In the conventional technology described above, the structure of the refrigerator body is complicated, and the refrigerator body is composed of a reinforcing plate, an inner box, a nonmetallic hard plate, and a heat insulating material. Since the metal decorative frame is separately screwed to the periphery of the front opening of the refrigerator, an extra metal decorative frame is required from the perspective of the refrigerator body. This increases the number of work steps and requires additional materials.

Therefore, the present invention aims to save materials by using a component of the refrigerator body as a decorative frame that covers the gap between the refrigerator body and furniture, etc., and also simplifies the process of joining the inner box and the outer box. This provides a configuration that allows for

(d) Means for Solving the Problems The refrigerator main body of the present invention includes an inner box having an outwardly facing flange on the periphery of the front opening, and an inner box having an outwardly facing flange on the periphery of the front opening. an outer box surrounding the inner box and having an inward flange spaced apart from the flange; a fitting part into which the outward flange fits; a front part covering the inward flange; and an outer box from this front part. a front decorative frame having an outwardly extending portion and a side surface joined to the outer surface of the outer box; an elastic sealing material in contact with the inward flange and the front decorative frame; The structure includes a foam heat insulating material filled in a space between the inner box and the outer box.

(E) Function After fitting the outward flange of the inner box and the front decorative frame, the outer box is assembled from the rear, and the inward flange of the outer box is attached to the back side of the front part of the front decorative frame through an elastic sealant. They are brought into contact with each other, and in this state, the outer case and the front decorative frame are connected. In this state, the space between the inner box and the outer box is filled with foam to complete the refrigerator body. That is, the front decorative frame constitutes a part of the outer box, and also functions as a decorative frame that covers the gap between the refrigerator body and furniture or the like.

(f) Embodiments Examples of the present invention will be described below with reference to FIGS. 1 to 3. 1 is an inner box with an opening 2 on the front;
An outward flange 3 is formed at the periphery of the opening 2. Reference numeral 4 denotes an outer box having an opening 5 on the front surface, and an inward flange 6 having a dimension that is located on the outside of the outward flange 3 while maintaining a distance from the outer flange 3 at the periphery of the opening 5. 7 is a front decorative frame, which includes a fitting part 8 into which the outward flange 3 fits, a front part 9 extending from the fitting part 8 and covering the inward flange 6, and a front part 9 continuous to the front part 9 of the outer box 4. It has a side part 11 fixedly connected to the outer surface of the front end with a screw 10. The fitting part 8 has a front wall 12 that comes into contact with the front surface of the flange 3 and a holding side 13 that comes into contact with the back side of the flange 3 with some elasticity. It is welded to the side 16 extending to the back side. When there is a considerable gap between the refrigerator main body and furniture, etc., the front decorative frame 7 is formed with an extending part 15 projecting outward in a size corresponding to the gap to cover the gap.
The component 14 of the holding side 13 of the fitting part 8 may have a structure in which a locking piece 18 is locked in a locking hole 17 formed in the side 16 as shown in FIGS. 1 and 3. Reference numeral 19 denotes an elastic sealing material affixed to the front surface of the inward flange 6.

In this configuration, first, the outward flange 3 of the inner box 1 is fitted into the fitting part 8 of the front decorative frame 7. This fitting is performed while the inner box 1 is slightly bent inward. After this fitting, the outer box 4 is moved from the rear of the inner box 1 and the elastic sealing material 19 is placed on the front surface of the inward flange 6.
After assembling them so that they come into contact with the back surface of the front part 9, the front decorative frame 7 is fixedly connected to the outer case 4 with screws 10. After this bonding, the space between the inner box 1 and the outer box 4 is filled with foamable heat insulating material 20 by a foaming-in-place method. As a result, the heat insulating material 20 is adhered to the inner box 1, outer box 4, and front decorative frame 7, making the refrigerator main body 21 strong.
is made.

FIGS. 4 and 5 show other embodiments of the present invention. In this, parts with the same names as those in FIGS. 1 to 3 will be described using the same reference numerals, and explanations will be omitted, and different constituent parts will be explained using new reference numerals.
At the front end of the outer box 4, there is a groove 24 that opens outward, and in the front part of this groove, there is an arcuate bulge 22 that bulges inward. A large number of holes 23 are formed. Front decorative frame 7
The holding side 13 forming the fitting part 8 is formed by bending the front wall 12 in series, and an extending part 15 is formed continuously from the front part 9, and the side part 11 is bent rearward. A locking portion 25 that locks into the groove 24 is bent at the rear end. The decorative frame 7 is separated at one point as shown in Fig. 4, and this is to facilitate the fitting operation between the flange 3 of the inner box 1 and the fitting part 8.After this fitting, the decorative frame 7 is separated into a frame shape. They are joined together with plates, tape, etc. to form a frame, and in this state, the outer box 4 is moved from the rear and the locking portions 25 of the decorative frame 7 are engaged with the grooves 24, thereby assembling and joining. In this state, by foaming the foamable heat insulating material 20 in the space between the inner box 1 and the outer box 4 on-site, a part of the heat insulating material 20 is inserted through the hole 23 into the groove made by the bulge 22. In order to penetrate and adhere to the side surface 11 of the decorative frame 7 at this part, the outer box 4
At the same time, the decorative frame 7 is fixed and the refrigerator main body 21 is strong.
is completed. In FIGS. 1 to 5, the sealing material 19 serves to prevent the heat insulating material 20 from leaking and to absorb dimensional errors in the outer box 4.

(g) Effects of the invention In this invention, since the front decorative frame constitutes a part of the outer box, there is no need to use a separate decorative frame from the refrigerator body, and there are fewer components, which is advantageous in terms of saving materials. This also has the effect of preventing leakage of the insulation material and absorbing dimensional errors of the outer box. Furthermore, it is relatively easy to assemble, and a built-in refrigerator that is structurally simple and strong can be achieved.
