Description

[Detailed description of the invention] This invention is a food storage system in which the inside of a refrigerator is divided into upper and lower storage chambers by a plate-shaped partition plate, and the lower storage chamber has an open top surface and is sealed by the partition plate. Regarding a refrigerator in which a container can be freely taken out and stored in the front, in particular, a cold air communication hole communicating with the lower storage chamber space around the food storage container and the upper storage chamber is provided at the edge of the partition plate, and the refrigerator compartment A partition front member is installed in the front part of the partition plate horizontally so as to divide the front opening of the storage compartment into upper and lower parts, and forms an airtight surface with the door that opens and closes the front opening of each of the storage compartments. In the case where the cold air communication hole is blocked by the stored items in the upper storage chamber, cold air circulation between the lower storage chamber and the upper storage chamber is obstructed, and the cooling effect in the food storage container is impaired. This is to prevent the storage space from being damaged and to make effective use of the space in the lower storage chamber.

Next, embodiments of the present invention will be described in detail based on the drawings.

1 is an outer box 2, an inner box 3, and a heat insulating material 4 filled between these two boxes.
A refrigerator body 5 is an insulating partition wall that partitions the inside of the refrigerator body 1 into a freezer compartment 7 in the upper part and a refrigerator compartment 6 in the lower part. A cooler 17 is housed in the refrigerator compartment 14, and an electric blower 13 is arranged in the cold air passage 12 at the rear extending between the refrigerator compartment 6 and the freezer compartment 7.
The air cooled by the cooler 17 is discharged to the freezer compartment 7 and the refrigerator compartment 6 through the cold air discharge ports 10 and 11, and the cold air suction port 18
It is inhaled and circulated from 19 and 19.

15 is an electric compressor that constitutes a refrigeration cycle including a condenser 16 and a cooler 17, and a part of the condensation pipe of this refrigeration cycle is arranged at the edge of the front opening of the refrigerator body 1 to prevent frost formation. A heating body 30 is used.

Reference numeral 20 denotes a partition front member installed horizontally so as to divide the front opening of the refrigerator compartment 6 into upper and lower parts at the middle thereof, and 9J and 1 include a heat insulating material 20B.

Reference numeral 21 is a partition plate made of synthetic resin that extends rearward from the front partition member 20 and divides the inside of the refrigerator compartment 6 into an upper storage chamber 8 and a lower storage chamber 9.

The front opening of each storage chamber 8, 9 has a door (not shown) that can be opened and closed independently pivoted to the refrigerator main body 1, and the front side of the partition wall 5 and the partition front member 20 are provided on the door. Acts as an airtight surface against which the gasket abuts.

A food storage container 28 is housed in the lower storage chamber 9 so that it can be taken out forward, and has a box shape with an opening at the top.

The storage container 28 has a space 9A in which cool air flows between its outer wall surface and the left and right side walls and rear wall, which are the inner wall surfaces of the lower storage chamber 9.
A plurality of cold air communication holes 26 are formed at the peripheral edge of the partition plate 21 corresponding to the space 9A.

The partition plate 21 is supported almost airtight by fitting the left and right ends and the rear end into grooves 22 formed in the inner box 3, and the front end is attached to a hook device 23 that can be attached to and detached from the lower surface of the front partition member 20. It is supported in a substantially airtight manner, and can be pulled out forward by removing the hook device 23.

Reference numeral 24 denotes a backing made of a soft material such as rubber to keep the top opening of the food storage container 28 airtight between the partition plate 21 and the food storage container 28 at a position inward of the cold air communication hole 26. The container 28 is attached to the lower surface of the plate 21.
The interior 29 is kept airtight, making it suitable for storing vegetables, etc.

Reference numeral 31 denotes a net shelf placed in the upper storage chamber 8 near the partition plate 21, and has a horizontal article placement surface 31B with a low step 31A between the front edge and the rear edge; It is placed on a front placement surface 20A formed in a row at the rear of the upper surface of the front member 20, and its rear edge is placed on a rear placement surface 25 formed on the left and right portions of the back wall of the upper storage chamber 8. .

In this configuration, the stepped portions 31A, 31A are formed such that the horizontal article placement surface 31B is located inward from the cold air communication holes 26 formed at the front and rear edges of the partition plate 21. , the article placement surface 31B approaches the −E surface of the partition plate 21, and a relatively narrow space 32 is created between the article placement surface 31B and the partition plate 21.

Cold air descends from the upper storage chamber 8 to the lower storage chamber 9 through cold air communication holes 26 formed at the rear edge and right and left side edges of the partition plate 21, passes around the food storage container 28, and passes through the front edge of the partition plate 21. The cold air is returned to the upper storage chamber 8 through the cold air communication hole 26 in the upper storage chamber 8.

Here, the bottom wall of the partition front member 20 is inclined so as to become higher toward the rear, forming an inclined surface 20C.

As a result, the cold air communication hole 26 can be brought forward by that amount, and the front end of the food storage container 28 can be expanded to below the partition front member 20.

That is, even if the front end of the food storage container 28 is located further forward than the rear end of the front partition member, it will be smoothly guided by the inclined surface 20C.

In this circulation, the presence of the step portions 31A at the front and rear of the net shelf 31 restricts the movement of the articles placed on the horizontal article placement surface 31B of the net shelf 31 in the front and back direction, and the partition plate 21
The cold air communication holes 26 formed at the front edge and rear edge are not blocked and the cold air can circulate smoothly.

Furthermore, due to the presence of the horizontal article placement surface 31 of the net shelf 31, the upper storage chamber 8 can be effectively used up to the partition plate 21, and since articles are not directly placed on the partition plate 21, damage will not occur. .

Furthermore, in the case where a large opening is provided in the center of the partition plate 21 and another lid plate is provided to close this opening, this lid plate is removably provided to introduce cold air into the storage container 28, as described above. The presence of the space 32 makes it possible to sufficiently introduce cold air.

Further, the space 32 is connected to the effect of indirectly cooling the inside of the storage container 28 through the partition plate 21 and cooling the articles on the net shelf 31 from the bottom.

By configuring the present invention as described above, the cool air circulation between the upper storage chamber and the lower storage chamber is not blocked by the articles on the net shelf at the stepped portions provided at the front and rear of the net shelf, and the cold air is stopped. The non-uniform temperature distribution caused by this is extremely reduced, making it ideal for a refrigerator with a partition plate for storing items that do not like to be dried, such as vegetables, in the lower storage chamber.

In addition, since the air in the space surrounding the food storage container is ensured to return to the upper storage chamber through the return path behind the partition front member,
Air in the upper storage chamber is smoothly supplied to the surrounding space through the cold air communication hole, and the stored items in the food storage container are quickly cooled.

Furthermore, since the partition wall has a separate structure consisting of a front partition member and a partition plate, the partition plate can be easily cleaned.

By forming the return path behind the front partition member, for example, compared to a method in which the return path is formed inside the front partition member, the insulation thickness in the direction of the front opening can be sufficiently thickened, and dew buildup on the front side of the front partition member can be prevented. In addition, since the bottom wall of the front partition member that forms the return path is an inclined surface, air convection is smooth.
In addition, since the cold air communication hole can be brought forward, the front wall of the food storage container protrudes relatively forward, increasing the effective internal volume of the food storage container.
