The present invention relates to a refrigerator equipped with an electrical component case, and more particularly, to a refrigerator having a reduced number of parts and improved recyclability.
[0002]
[Prior art]
Conventionally, refrigerators as shown in FIGS. 3 to 4 are known (for example, Japanese Utility Model Publication No. 10-18189, Japanese Utility Model Publication No. 62-152189). FIG. 3 is a longitudinal sectional explanatory view of the refrigerator before mounting electric / electronic parts and the like, and FIG. 4 is a perspective view of the refrigerator mounted with electric / electronic parts and the like.
1 is an outer box main body, 2 is an outer box back plate main body, 2A is an outer box back plate fixed to the outer box main body 1 and the outer box back plate main body 2, and 3 is an electric / electronic component 4 that is housed and mounted. It is attached so that it may follow the recessed part 2B formed in 2A of outer case back plates with the electrical component case formed with the synthetic resin. Reference numeral 5 denotes an inner box formed of a synthetic resin that serves as an inner wall of the refrigerator. Reference numeral 6 denotes a foamed polyurethane heat insulating material filled in a space between the inner box 5, the outer box back plate body 2 and the outer box back plate 2A. 7 is an outer box main body side wiring connection terminal, 8 is a lid for covering the electrical component case 3 mounted on the outer box back plate 2A, and 9 is a screw. The outer box body side wiring connection terminal 7 is connected to a wiring connection terminal on the side of the electric / electronic component 4 or the like.
The refrigerator is controlled by the electric / electronic component 4 and the like, and cool air cooled by a refrigerating cycle (not shown) is blown into the refrigerator so that the inside of the refrigerator is cooled.
[0003]
[Problems to be solved by the invention]
Although the outer box body 1, the outer box back plate body 2, the lid 8 and the like of the conventional refrigerator shown in FIGS. 3 to 4 are made of iron-based metal that is easy to recycle, the electrical component case 3 made of synthetic resin. Since the outer box back plate 2A to which the battery is mounted is formed of a flame retardant resin or a flame retardant resin composition, the outer box back plate is used when recycling and reusing each member after using the refrigerator. There was a problem that 2A had to be removed and recycled separately, which was troublesome and difficult to recycle.
Further, since the electrical component case 3 is attached using the screws 9, there is a problem that it is troublesome and complicated.
[0004]
Accordingly, a first object of the present invention is to provide a refrigerator that reduces the number of parts and has improved recyclability, and a second object of the present invention is to use an electrical component case without using screws. It is to provide a refrigerator that is easily fixed and attached to the outer box back plate.
[0005]
[Means for Solving the Problems]
The invention of claim 1 of the present invention is a refrigerator formed by foaming and filling a heat insulating material in a space between an outer box made of iron light metal and an inner box made of resin. and the electrical component case formed of a synthetic resin accommodates the electrical components including, for example, connecting portions of the various wires, and a recess formed in the rear surface of the outer box, and a lid made of a ferrous metal covering the recess A fixing tool for fixing the electrical component case to the recess, wherein one end is fixed to the electrical component case and the other end is provided through the outer box, and the heat insulating material is filled with foam. The refrigerator includes a fixed fixture , the electrical component case is housed in the recess, and the lid is attached.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.
FIG. 1 is a longitudinal cross-sectional explanatory view showing one assembling method of the refrigerator of the present invention before mounting electrical / electronic parts, etc. FIG. 2 (A) is a longitudinal section showing another assembling method of the refrigerator of the present invention. FIG. 2B is an explanatory diagram showing an enlarged plane of a hole for inserting the head of the fixture.
[0008]
1-2, 1 is an outer box body made of iron-based metal, 2 is an outer box back plate body, and 2C is made of an iron-based metal fixed to the outer box body 1 and the outer box back plate body 2. The outer box back plate 3A is an electrical component case formed of a synthetic resin that accommodates and mounts electrical and electronic components (not shown). The electrical component case 3A is inserted in the direction indicated by the arrow to It attaches along the recessed part 2B formed in 2 C of face plates. Reference numeral 5 denotes an inner box formed of a synthetic resin that serves as an inner wall of the refrigerator. Reference numeral 6 denotes a foamed polyurethane heat insulating material filled in a space between the inner box 5, the outer box back plate body 2 and the outer box back plate 2C. 7 is an outer box main body side wiring connection terminal, and 8 is a lid formed of an iron-based metal covering the electrical component case 3A attached to the outer box back plate 2C. The outer box body side wiring connection terminal 7 is connected to the wiring connection terminal on the side of the electric / electronic component 4 as shown in FIG.
The refrigerator is controlled by an electric / electronic component 4 (not shown) and the like, and cool air cooled by a refrigeration cycle is blown into the refrigerator so that the inside of the refrigerator is cooled.
[0009]
Filled the space between the inner box 5 and the outer box back plate 2C through the outer case back plate 2C with the L-shaped fixture 10 fixedly attached to the surface where the electrical component case 3A contacts the outer box back plate 2C. The electrical component case 3 </ b> A is mounted on the outer box back plate 2 </ b> C by being embedded in the foamed polyurethane heat insulating material 6.
[0010]
The electrical component case 3A is attached using a plurality of L-shaped fixtures 10 provided at the bottom of the electrical component case 3A as described above, without using screws or the like. Can be attached to. The L-shaped fixture 10 of the electrical component case 3A is formed in an L-shape as shown in FIGS. 1 to 2 even if the L-shaped fixture 10 is integrally formed on the bottom of the electrical component case 3A. The mold fixture 10 may be formed separately from the electrical component case 3A, or may be a combination of both, and is not particularly limited. A method of forming the L-shaped fixture 10 separately from the electrical component case 3A is preferable because the electrical component case 3A can be attached more easily.
[0011]
A method of forming the L-shaped fixture 10 separately from the electrical component case 3A and mounting the electrical component case 3A on the outer box back plate 2C using the separately formed L-shaped fixture 10 will be described. First, after the L-shaped fixture 10 is installed through the hole 11 provided in the outer box back plate 2C in advance, the polyurethane foaming composition is poured into the space between the inner box 5 and the outer box back plate 2C to foam. Then, the L-shaped fixture 10 is embedded and attached to the foamed polyurethane heat insulating material 6 filled in this space. Then, the electrical component case 3A is inserted in the direction indicated by the arrow, the head 13 of the L-shaped fixture 10 corresponding to the hole 12 provided in the bottom of the electrical component case 3A is inserted, and the electrical component case 3A is It is mounted on the outer box back plate 2C.
[0012]
In the example illustrated in FIG. 2A, an example in which the fixing auxiliary portion 14 is integrally provided below the head 13 of the L-shaped fixture 10 is illustrated. FIG. 2B is an explanatory view showing the plane of the hole 12 in an enlarged manner. Since the fixing auxiliary portion 14 is integrally provided below the head 13 of the L-shaped fixture 10, the L-shaped fixture 10 can be more reliably and easily installed on the outer box back plate 2C. Moreover, since the four notches 15 are provided at equal intervals around the hole 12, the head 13 of the L-shaped fixture 10 corresponding to the hole 12 can be inserted more easily.
[0013]
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit described in the claims.
