Description

[Detailed description of the invention] The present invention is a refrigerator in which the refrigerator main body is divided by a partition wall, the upper part is a freezing compartment, and the lower part is a refrigerator compartment, and air cooled by a cooler is circulated to the compartments by an electric blower. When the cold air outlet to the refrigerator compartment is provided in the back wall of the refrigerator, an article storage container installed along the soil wall of the refrigerator compartment and an article storage container installed at the upper part of the back side of the door that opens and closes the front opening of the refrigerator compartment. The purpose is to cool the shelves well.

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

Reference numeral 1 denotes a refrigerator main body, which has a heat insulating structure in which a heat insulating material 4 is filled between an inner box 2 and an outer box 3, and a partition wall 5 containing the heat insulating material divides the inside of the main body into an upper storage compartment, that is, a freezing compartment 6, and a lower storage compartment. That is, it is divided into a refrigerator compartment 7.

The temperature of the freezer compartment 6 and the refrigerator compartment 7 becomes low because air cooled by a cooler 9 housed in a cold air passage 8 in the partition wall 5 is circulated by an electric blower 10 as shown by the arrow.

The cooler 9 does not need to be in the partition wall 5 as long as it is in the cold air passage communicating with the freezer compartment 6 and the refrigerator compartment 7.

The cold air outlet 11 to the refrigerator compartment 7 is located at the upper part of the back wall of the refrigerator compartment 7 and is located between the left and right sides, for example, in the center. Part 1
2, an actuation mechanism section 13 that operates in response to pressure increases and decreases due to the gas sealed in the temperature sensing section, and further this operation mechanism section 1.
It is opened and closed by the opening/closing plate 14 of a damper set thermostat 15, which is provided with an opening/closing plate 14 that reciprocates in response to the operation of step 3.

This thermostat 15 is housed in a case 16 and attached to the back wall of the refrigerator compartment 7 via a sealing material 17.

The cold air discharged from the cold air outlet 11 is deflected by the opening/closing plate 14 and flows out into the refrigerator compartment 7 from the cold air outlet 18' formed by the opening 18 at the top of the case and the upper wall 7A of the refrigerator compartment 7.

A lower wall 5A of the partition wall 5 on which the cooler 9 is mounted is vacuum formed integrally with the inner box 2, and the back side is filled with a heat insulating material 4, forming a part of the upper wall 7A of the refrigerator compartment 7. are doing.

A plurality of upwardly recessed grooves 19 are formed in the left and right intermediate portions of the upper wall 7A and extend linearly from the rear to the front, and are connected to cold air discharge ports 18' to the refrigerator compartment 7. The rear end opening corresponds to the cold air discharge port 18' and extends almost to the front end of the lower wall 5A so that a portion of the cold air discharged from the groove flows forward along the upper wall 7A.The front end opening of the groove 19 will be described later. The openings are opposite to each other on the fence 24.

Reference numeral 21 denotes an article storage container disposed directly below the groove 19 along the upper wall 7A, and placed on a pair of left and right protrusions 22 provided on the side wall of the inner box 2 so as to be slidable in the front and rear direction. This is for storing opened fish, meat, etc. in the refrigerator compartment 7 at a low temperature.

Reference numeral 20 denotes a cold air suction passage in the partition front member 5B constituting the partition wall 5, which communicates with the cold air passage 8, and has a cold air suction port 2O at the lower end.
A opens into the refrigerator compartment 7.

Reference numeral 23 denotes a door pivoted to the main body 1- to open and close the front opening of the refrigerator compartment 7, and on the back side there are article mounting machines 24, 2 in multiple stages.
4'.

24'' is provided.

The topmost fence 24 constitutes an egg shelf in the figure, and when the door 23 is closed, both ends of the fence 24 are connected to the cold air intake ports 20A on both sides.
, 20A.

Furthermore, the fence 24 is located in front of the article storage container 21.

In this state, there is a gap between the container 21 and the fence 24 through which the air in the refrigerator room flows.

In such a configuration, a part of the cold air discharged from the cold air outlet 18' flows through the cold air guide groove 19, a part of the cold air flowing through this groove descends into the container 21, and the cold air that advances through the groove 19 flows into the groove. The front end of 19 descends onto the fence 24.

The cold air that has descended to the middle part of the container 21 cools the inside of the container 21 almost uniformly while flowing toward the cold air suction port 2OA.

In addition, the cold air that has fallen to the middle part of the fence 24 is also removed from the cold air intake port 20A.
Since the flow is directed toward the air, the top of the fence 24 can be cooled approximately evenly.

Furthermore, in the present invention, if a plurality of grooves 19 are provided on the left and right sides and the center part of the upper wall 7A, even if the fence 24 is separated into left and right sides by the partition wall 25 in the center part, the left groove 19 If the right groove 19 is formed to correspond to the right fence 24, the same effect can be obtained.

As described above, the refrigerator compartment has a cold air outlet in the upper part of the back wall, a cold air inlet in the front part of the mud wall that communicates with the cold air passage in the partition wall, and an article storage container with an opening on the top surface installed in the refrigerator; an article placement machine is provided on the upper back side of the front door of the refrigerator compartment; and the cold air outlet is provided in the earthen wall of the refrigerator compartment corresponding to the article storage container. In this configuration, a cold air guide groove extending toward the article mounting machine is provided in front of the article mounting machine.

For this reason, the cold air outlet to the refrigerator compartment is connected to the back wall of the refrigerator compartment.
In a refrigerator in which the cold air outlet is opened and closed by a thermostat with a damper set, a storage container is provided along the earthen wall of the refrigerator compartment, and the container is located at the front of the container at the upper part of the back of the front door of the refrigerator compartment. Even in the case where an article placement machine is provided on the shelf, the cold air discharged from the cold air discharge port is guided forward by the cold air guide groove, descends into the container on the way, and the cold air that advances further forward is placed on the shelf. The container and the items on the shelf can be cooled by descending to the top of the shelf.

Further, the cold air guide groove extends forward in the central part of the earthen wall of the refrigerator compartment corresponding to the cold air discharge port, and its front end is opened corresponding to the fence, and the cold air suction port is located at the left and right ends of the fence. By opening the refrigerator, it is possible to improve the circulation of cold air within the refrigerator compartment and the cooling of the containers and shelves, thereby providing a refrigerator with a simple structure.
