Description

[Detailed explanation of the invention] Refrigerators have recently become available in a wide variety of sizes, from small to large, and for general household use, there is a gradual shift towards larger sizes, but as refrigerators become larger, they become more difficult to transport and install. come. In particular, considering the current structure of Japanese houses, these problems will become more and more serious as demand for large refrigerators increases.

This invention was devised in view of the above matters,
The present invention relates to an improved structure of a so-called separate type refrigerator in which the heat insulating boxes forming the refrigerator body are appropriately separated and transported separately, and the plurality of heat insulating boxes are combined at the time of installation.

A detailed explanation will be given below using an example shown in the drawings.
1 and 2 are insulated boxes with opening/closing doors 3 and 4 pivotally attached to the front so that they can be opened and closed, and one of the insulated boxes (1 shown here) houses a refrigeration cycle including a cooler, compressor, condenser, etc. Unit (none shown)
The other insulating box (2 shown here) is not equipped with a refrigeration cycle unit, and these insulating boxes 1 and 2 are each transported independently, and when installed, they are not installed vertically or horizontally. juxtaposed with. When these insulating boxes 1 and 2 are integrally connected, the insides of each insulating box 1 and 2 are communicated through an outgoing duct and a return duct (none of which are shown), and from insulating box 1 equipped with a refrigeration cycle unit. The cold air is forcibly circulated into another insulating box body 2. Reference numeral 5 denotes a connecting part for integrally joining the above-mentioned insulating boxes 1 and 2, and in the above embodiment, it is fixed to the upper back surface of the insulating box 1, and the 2 parts of the other insulating box are attached to the upper end thereof. It has an engaging protrusion 8 that is engaged with the recess 7 of the receiver 6 fixed to the lower part of the back surface, and a cover 9 at the lower end for covering the joint between the recess 7 and the engaging protrusion 8. It is rotatable. The coupling part 5 is integrally molded with the cover 9 from a synthetic resin material, and one end of the cover 9 is provided with an engaging pawl 11 that can be engaged with and detached from a recess 10 formed at the upper end of the receiver 6. have. 12,1
Reference numeral 3 denotes lead wires from electrical components led out from the back surfaces of the heat insulating boxes 1 and 2, and connected to the electrical components via a connector 14 so that they can be connected to and separated from each other. 15 and 16 are fixing screws, and 17 is a space formed by the cover 9.

Here, the assembly operation of the refrigerator of the present invention will be explained. When assembling the refrigerator, another heat-insulating box 2 is placed on top of the heat-insulating box 1, and the engaging protrusion 8 of the connecting part 5 is fitted into the recess 7 of the receiver 6. The lead wires 12 and 13 led out from the heat insulating boxes 1 and 2 are connected through the connector 14, and the engaging claws 11 are connected to the receiver 6 of the heat insulating box 2 so as to cover the cover 9 from above. What is necessary is to engage the concave portion 10 of. By doing this, it is possible not only to integrally connect the plurality of heat insulating boxes 1 and 2, but also to hide the joints of the joint parts 5 and the lead wire connections, which are unsightly in appearance, with the cover 9. .

In the present invention, as described above, the cover that covers the connection portion of the electrical wiring led out from each insulating box has the function of connecting the plurality of insulating boxes, so that the mechanical connection is not necessary. and electrical connections can be made at the same location, which not only improves the ease of assembly when installing the refrigerator body, but also prevents you from forgetting to connect electrical wiring, and the electrical connection parts are covered with a cover. As a result, electrical connections are not exposed to water and are safe, and mechanical and electrical connections are not visible from the outside, resulting in an extremely good appearance. Since there is no need to provide a coupling means separately from the cover, the number of parts can be reduced, and the number of man-hours required for coupling can be omitted, resulting in significant cost reductions.
