In the publication, a pair of duct plates having a plurality of horizontally elongated discharge openings vertically provided in front of and behind each other are provided in a heat insulating structure,
The shelf is supported by the metal fittings locked to this duct plate, and a heating unit such as an evaporator and an electric heater is provided above the interior of the refrigerator, and cool air or heated air is circulated and supplied by a blower to defrost and cool the food on the shelf. Is disclosed.

In Japanese Patent Application Laid-Open No. 2-4187, a cooling chamber and a storage chamber are defined in a refrigerator by a vertical partition plate having a slit-shaped suction port at the center and air outlets at the top and bottom. The cooler is provided with a suction port, and a blower for discharge is disposed in the cooling chamber corresponding to each discharge port, while the storage room is provided with shelf supports fixed to the inner side wall and the partition plate, Disclosed is a cooling storage in which a cooled object is placed on a rail-shaped shelf which is locked to the shelf support at an appropriate interval so as to be freely taken in and out, and cool air heat exchanged by a cooler is circulated through upper and lower outlets to a storage room. Have been.

[0004] Here, the rear ends of shelves, which are generally arranged vertically in the refrigerator, are installed so as to secure a circulation path for cool air with an interval between the shelf and the back wall of the refrigerator. For example, as disclosed in FIG. 2 of the latter publication, a stopper portion for pressing down the object to be cooled is bent and formed on the rear shelf support, and a space 1 is formed in the rear portion.
6c is formed.

[0005] Rather than placing foods and the like directly on a shelf, a tray is used which slides on a rail-shaped receiving member so that it can be moved in and out of the front and back, and a type of refrigerator in which goods are stored in the tray. Also in this case, the rear end of the tray is not brought into contact with the inner back wall, but is stopped in front to secure a required space behind.

Specifically, a locking hole is provided at the rear end of the rail-shaped receiving member, and a separate stopper member is locked and attached to this hole.

[0007]

However, in a refrigerator using a tray as described above, conventionally, a stopper is attached to each rail-shaped receiving member, and it takes a lot of trouble when the number of receiving members is large. There was a problem.

In addition, the position of the stopper cannot be lowered so much to secure a circulation path for cool air, and as a result, it has to be mounted on the front side.

[0009] Therefore, there is a problem that only a small tray can be accommodated in comparison with the size of the inside of the storage, and the storage capacity is small and the capacity of the storage cannot be effectively used at present.

The present invention has been made in view of the above points, and has been improved so that a large tray can be used, the effective use of the inside of the refrigerator can be measured, and the tray can be mounted without using a stopper. It is an object of the present invention to provide a cooling storage configured to improve usability.

Similarly, a pair of shelf supports are provided in front of the remaining three storage rooms, and a rear duct is provided in the rear.
The tray 18 is supported so that it can be freely taken in and out.

As shown in FIG. 3, a dew receiving plate 35 having a drainage passage 34 is provided below the cooler 5 so as to be inclined backward, and defrost water and the like are supplied to the back wall 31 and the bottom wall 36 of the main body 1A. The water is discharged from a drain water drain 38 through a drain hose 37 disposed along the outer surface of the drain.

When the compressor 12 and the cool air circulation fan 6 are operated, the air in the refrigerator is sucked into the cooling chamber 7 and the cool air cooled by the cooler 5 is supplied to the rear duct 26. At the same time, the air is guided so as to flow downward through the circulation path 8 of the cool air, and at the same time, is circulated so as to blow out uniformly from each of the cool air blow-out holes 29 to the space between the tray 18.

As a result, the stored items in the trays 18 at any stage are uniformly cooled.

As described above, the cool air circulation path 8 for circulating the cool air from the cooler 5 to the lower stage and supplying the cool air to each tray 18 is provided in advance by installing the back duct 26 at the back inside the refrigerator. Since the tray 18 is secured, the tray 18 can be inserted until the rear end thereof hits the rear duct 26 without stopping the tray 18 slightly before the inner back wall.

As a result, a large tray 18 can be used, and the interior 3 can be used effectively.

Further, since the back duct 26 itself also serves as a stopper for the tray 18, it is possible to save the trouble of attaching a stopper member to each receiving member 19 one by one as in the related art, thereby improving the usability.

[0037]

As described above, according to the present invention, two shelves supporting the tray are provided on the left and right sides of the shelf, which serves as a stopper for stopping the tray at the same time as circulating the cool air to the rear side. Since the cooling storage has a structure with a rear duct that is integrally formed, the conventional mounting method is to place the tray a little before the innermost part of the inside of the refrigerator to secure the circulation path of cool air at the back when inserting the tray This allows for larger trays to be inserted, which allows more efficient use of the storage space and increases storage capacity. In order to stop the tray, the work of attaching the stopper member to the tray holder, which was conventionally performed, is not required, so that the usability is improved, and the number of parts is reduced by eliminating the stopper member, and the structural Simplification can be achieved. Furthermore, since the circulation path of the cool air is constructed by the back duct, the circulation of the cool air can be ensured.Moreover, since the blow duct of the cool air is opened in this back duct in accordance with each pitch of the tray, Cool air can be surely and uniformly guided to each tray, and excellent effects such as efficient and uniform cooling of the inside of the refrigerator can be achieved.
