Description

[Detailed description of the invention] The present invention relates to a refrigerator that uses a blower to forcefully circulate cold air between the freezer compartment and the refrigerator compartment.In particular, when the cold air flows crosswise between the two compartments, cold air leaks from the periphery of the front door. The present invention provides a structure in which the temperature regulator for controlling the operation of the refrigeration cycle is installed at the front of the freezing chamber, thereby improving operability.

Next, embodiments of the present invention will be described in detail based on the drawings. 1
is a refrigerator main body, and the inside of the refrigerator is vertically divided into a freezing compartment 3 and a refrigerating compartment 4 by a horizontally arranged insulating partition wall 2. 5 is a cold air passage formed in the partition wall 2;
A cooler 6 in a refrigeration cycle is housed therein. Reference numeral 7 denotes a door for opening and closing the front opening of the freezer compartment 3, and an opening/closing door 22 is also provided at the front of the refrigerator compartment 4.
Each of them is rotatably supported on one side of the main body 1. 8 is a cold air rising passage formed along one side wall orthogonal to the door 7 of the freezer compartment 3, and the cold air is lifted by an electric blower 9 disposed downstream of the cooler 6 in the cold air passage 5. Reference numeral 10 denotes a cold air supply path to the refrigerator compartment 4, and the cold air ascending passage 8 and the cold air supply path 10 can be formed by attaching these passage forming members to the outer surfaces of the inner boxes of the freezer compartment and the refrigerator compartment, respectively. Reference numeral 11 denotes a cold air discharge port for discharging the cold air from the cold air ascending passage 8 into the freezer compartment 3;
Reference numeral 12 indicates a cold air intake port formed on the other side wall of the freezer compartment 3 to guide cold air from the freezer compartment to the cold air passage 5, and reference numeral 13 indicates an outlet for cold air sent out from the cold air supply passage 10, depending on the temperature of the refrigerator compartment 4. The main body of the thermal damper device, except for the damper part, is covered with a heat insulating material and covered with a cover 15 forming a cold air outlet 14 to the refrigerator compartment 4. A cold air suction port 16 is formed on the other side wall of the refrigerator compartment 4 and guides cold air from the refrigerator compartment 4 to the cold air passage 5. Reference numeral 17 denotes a door pocket formed on the back surface of the freezer compartment door 7, and projecting walls 18 extending longitudinally are provided on the left and right sides. 19
1 is a front wall provided over substantially the entire length of the cold air rising passage 8, in which a temperature regulator 20 covered with a heat insulating material is disposed. The temperature regulator 20 operates to control the operation of the refrigeration cycle, that is, the operation of the electric compressor, so as to control the temperature of the freezing chamber 3. 21 is the front wall 1
The operating point of the temperature control is adjusted by the operation part of the temperature regulator 20 disposed on the front side of the temperature controller 9 . The operating portion 21 is arranged to correspond to the protruding wall 18 on the back surface of the freezer compartment door 7 on the opposite side from the pivot side. For this reason, since the door 7 can be opened slightly and the operating section 21 can be operated, leakage of cold air from the freezer compartment 3 can also be reduced. The same applies to the operation of the thermal damper device in the refrigerator compartment. FIG. 3 shows the configuration of the cold air discharge port 11 and the cold air ascending passage 8 in another embodiment. In this case, the front wall 19 may be formed to a portion where the cold air rising passage 8 is widened corresponding to the cold air discharge port 11, and the temperature regulator 20 may be housed in this widened portion.

In the above configuration, the air cooled by the cooler 6 is passed through the cold air ascending passage 8 by the blower 9 to the freezer compartment 3.
The cold air is circulated through the cold air supply path 10 to the refrigerator compartment 4, and as shown by the arrow, the circulation is between the freezer compartment 3 and the refrigerator compartment 4.
During this time, the inside of the pocket 17 in the freezer compartment door 7 is partially cooled, and the pocket 23 of the refrigerator compartment door 22 is similarly cooled. An operating section 24 of the thermal damper device 13 is provided so as to correspond to and be close to the left and right vertical walls 25 of the pocket 23 of the refrigerator compartment door 22. In such circulation, the front wall 19 allows the cold air from the cold air outlet 11 to flow through the door 7.
The protruding walls 18, 25 of the pockets of each door 7, 22 also act effectively as a barrier to cold air from the left and right peripheries of the door.

As described above, in the present invention, the flow of cold air in the freezer compartment and the refrigerator compartment crosses each compartment, and the proportion of the cold air colliding with the door of each compartment is extremely reduced. This reduces the amount of cold air leaking from the peripheral edge of each door, making it possible to maintain each room at a sufficiently low temperature without complicating the seal structure including the gasket attached to the door in that area. In addition, the front wall of the cold air ascending passage not only prevents leakage of the discharged cold air but also functions effectively as a housing section for the temperature controller, and the operating section thereof can be placed closer to the front of the freezer compartment, allowing the articles to be stored in the freezer compartment. It is possible to perform operations without interference from other people, and the space inside the refrigerator can be used effectively. It also makes it easier to install the thermal damper device in the refrigerator compartment closer to the front.
It is also possible to achieve a structure with improved operability.
