[Detailed description of the invention] Industrial application field This invention relates to the housing structure of a storage, and more specifically, in a storage that has a double structure in which a storage box is inside an insulated box, the storage box can be easily arranged. It is configured in a way that allows it to be removed from the insulation box and installed, facilitating maintenance and inspection of the cooling system, and
The present invention relates to a storage housing structure that allows the opening size of a heat insulating box to be set small to improve operability and suppress the escape of cold air.

Prior Art When storing fresh foods such as vegetables, fruits, meat, and fish (hereinafter referred to as "ingredients") in a refrigerator for a long period of time, or when gradually thawing frozen foods, it is common to It is necessary to keep temperature changes to a minimum and to control the evaporation of moisture from foodstuffs. In response to this request, a storage box for food storage is formed inside the insulated box that forms the refrigerator compartment, and cold air cooled by a cooler is placed in the cold air passage defined between the insulated box and the storage box. A storage box configured to cool the inside of a storage box by circulating water has been proposed and has been suitably implemented.

An example of a storage with a double structure in which a storage box is placed inside a heat-insulating box is shown in Figures 8 and 9.
As shown in the figure. The storage shown in the figure includes an outer box 2 having a large rectangular opening 2a on the front side, and a rectangular opening 2a that also opens large on the front side and is built into the outer box 2 with a required gap. It has a heat insulating box body 1 consisting of an inner box 3 having an inner box 3a and a heat insulating material 4 made of foamed urethane or the like filled between both boxes 2 and 3. The inner box 3 in this heat insulating box body 1
A storage box 10 made of a thermally conductive metal plate such as stainless steel is disposed inside the storage box 10 while maintaining a predetermined space with the inner wall of the storage box 10 . Further, the storage box 10 is
A rectangular opening 1a provided in the heat insulating box 1
It has a rectangular opening 10a that opens to the front corresponding to the opening.

Further, a cooler 5 is disposed between the inner side wall of the inner box 3 and the outer side wall of the storage box 10, and is connected to a refrigeration system (not shown). This cooler 5 includes a direct cooling type that circulates the refrigerant from the freezing device to the built-in evaporator, and a direct cooling type that circulates the refrigerant from the freezing device to the evaporator installed in the brine tank. There is an indirect cooling type that cools the brine and circulates it through a heat exchanger. Regardless of the type, the illustrated cooler 5 is surrounded by a cooling duct 6 that is open at the bottom, and a blower fan 8 provided in an opening 7 above the duct 6 sucks air inside the refrigerator from below the duct. After this is cooled by the cooler 5, it is blown out from the opening 7 to cool the inside of the refrigerator.

That is, cold air blown out from the blower fan 8 circulates in the space 9 as shown by the arrow, and cools the storage box 10 made of a good thermal conductor. As a result, the temperature of the wall surface forming the storage box 10 decreases, and the food (not shown) stored in the storage box 10 is cooled.
Note that a large number of holes are bored in a part of the storage box 10 to communicate the space 9 with the inside of the storage box, and a part of the cold air is directly introduced into the storage box 10 through these holes. Storage units configured to promote cooling of food materials have also been proposed.

Problems to be Solved by the Invention In the storage described above, a cooler 5, a cooling fan 8, and an internal thermostat (not shown), a defrosting thermostat, and a defrosting thermostat are installed between the inner box 3 of the insulating box body 1 and the storage box 10. A cooling system 11 consisting of members such as a heater is provided. When the cooling system 11 breaks down for some reason and maintenance work such as investigating the cause of the failure and replacing parts is performed, the storage box 10 must be removed from the heat insulating box body 1 prior to the work. Must be. Therefore, the front opening 1a of the insulation box 1
larger than the external dimensions of the storage box body 10,
It is possible to take it out from the opening 1a.

However, if the front opening 1a is configured to be large, as can be seen from FIG. 9, the size of the heat insulating door 12 that closes this opening 1a will also inevitably become large. For this reason, the opening/closing trajectory of the heat insulating door 12 becomes longer, which reduces operability in a narrow kitchen, and furthermore, when the door is opened, more cold air escapes from inside the refrigerator, increasing food temperature and power consumption. There were other problems.

Therefore, it is proposed to reduce the size of the heat insulating door 12 to deal with this problem. But this time,
The opening size of the front opening 1a is set smaller than the external size of the storage box 10, so that the storage box 10 cannot be taken out of the refrigerator. For this reason, the cooling system 11
When maintenance and inspection of the insulating box 1 is required, a part of the insulating box 1 is disassembled and removed to remove parts such as the cooler 5.
Other drawbacks have been pointed out, such as the structure becoming complicated and the need to move the refrigeration system disposed near the cooling system 11.

Furthermore, a part of the cold air circulating in the space 9 is transferred to the storage box 1.
In a storage structure in which the food is introduced into the box through the hole bored in the inner box 3, juices and odors generated from the food tend to adhere to the inner wall surface of the inner box 3 through the hole, and from a sanitary point of view, Requires regular cleaning. However, as described above, it is not easy to take out the storage box 10 from the heat insulating box 1, and therefore it is often used without being cleaned. For this reason, the container was left in an unsanitary condition, and the juice and the like adhering to the inner wall of the inner box 3 deteriorated, causing problems such as rusting on the metal parts inside the refrigerator.

Purpose of the invention This invention was proposed in order to suitably solve the above-mentioned problems inherent in the double-structured storage where the storage boxes are arranged inside the insulated box. , the storage box can be easily removed and attached to the insulating box to facilitate maintenance and inspection of the cooling system, and the opening size of the insulating box can be set small to improve operability and cool air. The purpose is to provide an effective means for preventing the escape of children.

Means for Solving the Problems In order to overcome the above-mentioned problems and achieve the intended purpose, the present invention consists of an outer box, an inner box, and a heat insulating material filled between the two boxes. A heat insulating box body having an opening that opens; a storage box disposed in a predetermined space from the inner wall of the inner box and having a front opening that opens in correspondence with the opening; An insulated door that can open and close the front opening,
In the storage consisting of the heat insulating box body and a cooler disposed between the heat insulating box and the storage box, the storage box is composed of a plurality of segments that can be divided, and the external dimensions of each segment are the same as those in the heat insulating box. It is characterized by being set smaller than the opening size at the front opening of the body.
