Cooling air supply structure of a refrigerator {STRUCTURE FOR COOLING AIR SUPPLY IN REFRIGERATOR}
[15] The present invention relates to a cold air supply structure of a refrigerator, and more particularly, to a cold air duct and a cold air discharge port formed in a door part of a side by side type refrigerator.
[16] In general, the side-by-side type refrigerator has a relatively large capacity and is equipped with various functions, and the freezer compartment and the refrigerating compartment are installed at the left and right sides of the refrigerator such that the freezer compartment and the refrigerating compartment are vertically vertically respectively, and a cooler chamber having an evaporator mounted on the rear side of the freezer compartment. It is provided to suck the air in the freezer compartment and the refrigerating chamber to the lower side and discharged to the upper side at the same time to be configured to perform the refrigerating and freezing functions respectively by circulating into each chamber.
[17] These side-by-side refrigerators are configured to be selectively moved up and down in the shelves for storing foods, etc., respectively in the refrigerator, and among them, a separate food container may be stored in a lower part of the upper shelf. Some food containers are also provided.
[18] 1 is a longitudinal sectional view showing the structure of a cold air circulation system of a conventional side-by-side refrigerator.
[19] As shown, the cold air circulation system of the conventional side-by-side type refrigerator is formed in parallel to each other and separated by the trimming section 6, the freezer compartment (F) and the refrigerating chamber (R), and the freezer compartment (F) The cooler chamber 1 which is separated and formed so as to form a space separate from the freezing chamber F at the rear, and the evaporator 2 and the blower fan 3 are installed, and the cold air generated in the cooler chamber 1 is the refrigerating chamber R. The supply duct 4 formed at the upper side of the trimming section 6 so as to be supplied to the cooling section and a passage through which the cold air whose temperature has risen in the refrigerating chamber R is returned to the cooler chamber 1 at the lower side of the trimming section 6. And a damper (8) for adjusting the amount of cold air provided and provided on the refrigerating chamber side of the supply duct (4).
[20] The cold air generated by the evaporator 2 is supplied to the freezing chamber F and the refrigerating chamber R by the blower fan 3, and the cold air that has risen in temperature by heat exchange with the stored foods stored in each chamber is evaporated again. The inside of the refrigerator is cooled while repeating the circulation returned to the side.
[21] On the other hand, in the case of a general refrigerator in which the freezer compartment is located at the upper part of the refrigerating compartment, since the cold air whose temperature has risen in the refrigerating compartment is taken back to the evaporator located at the back of the freezer compartment as the upper part of the refrigerating compartment, it is quite suitable for the configuration of the cold air discharge port and the suction port. In the case of side-by-side refrigerators, the cold air that has risen in the refrigerating compartment only needs to be returned through the cold air inlet formed at any position on the side of the refrigerating compartment, so that the positions of the cold air outlet and the inlet can be freely configured. Has an advantage.
[22] Therefore, it is proposed that a plurality of cold air discharge ports are formed inside the refrigerating chamber R for even cooling of the entire interior thereof, and the rear discharge port 9, the upper discharge port 10, and the side surface as shown in FIG. Discharge port 11 and the like.
[23] In fact, the biggest problem when using the refrigerator is the loss of cold air due to the opening and closing of the door, and the part that needs intensive cooling especially for even temperature distribution inside the refrigerator is the part where the most frequent items are stored in the refrigerator. That is, it can be said that the portion of the door basket in which the beverage is stored.
[24] However, in the conventional cold air supply structure of the refrigerator, the cold air supply structure is configured by ignoring the necessity of the arrangement of the cold air discharge ports as described above. Therefore, the side of the refrigerator is efficiently cooled by the same amount of cold air. Has been pointed out as a problem.
[25] The present invention is to solve the above problems, to provide a more efficient cold air supply structure of the refrigerator, which can achieve an even temperature distribution inside the refrigerator.

[26] In order to achieve the object as described above, the present invention is formed on one side of the rear of the refrigerating chamber, the supply duct for supplying the cold air introduced from the freezing chamber; A ceiling surface duct formed on the ceiling surface of the refrigerating compartment from the supply duct toward the front; A ceiling surface discharge port formed at a front end of the ceiling surface duct and configured to discharge cold air supplied below the refrigerating chamber; A door suction port formed on an upper surface of the door of the refrigerating compartment and connected to the ceiling discharge port when the door is closed to receive cold air; A door duct formed inside the door from the door inlet downward; A door discharge port formed at a middle or an end of the door duct and configured to discharge cold air supplied toward the inside of the door; And the door discharge port is configured to discharge cold air toward the door basket installed on the inner surface of the door.
[27] In addition, the door duct is branched toward both sides from the central portion of the door to form a branch duct, the door discharge port is preferably formed at the end of the branch duct.
[28] Further, it is preferably configured to include a rib for fixing the door basket to the inner surface of the door, the door discharge port is preferably formed in the rib.
[29] Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.
[30] 2 to 4 show the cold air supply structure of the refrigerator according to the present invention, FIG. 2 is a side cross-sectional view showing a state in which the door is closed, and FIG. 3 is a side cross-sectional view showing a state in which the door is opened, FIG. Is a rear view showing the inner surface of the door.
[31] As shown, a refrigerator air supply structure of the refrigerator according to the present invention includes: a supply duct 4 formed at one rear side of the refrigerating chamber R to supply the cold air introduced from the freezing chamber F; A ceiling surface duct 22 formed on the ceiling surface of the refrigerating chamber R toward the front from the supply duct 4; A ceiling surface discharge port 23 formed at the front end of the ceiling surface duct 22 for discharging cold air supplied below the refrigerating chamber R; A door suction port 24 formed on an upper surface of the door D of the refrigerating compartment and connected to the ceiling discharge port 23 when the door D is closed to receive cold air; A door duct 25 formed inside the door D from the door suction port 24 downward; A door discharge port 26 formed at the middle or the end of the door duct 25 to discharge cold air supplied toward the inside of the door D; It is configured to include, the door discharge port 26 is characterized in that it is formed to discharge the cold air toward the door basket 14 installed on the inner surface of the door (D).
[32] In addition, the door duct 25 is branched from the center portion of the door D toward both sides to form the branch duct 25a, and the door discharge port 26 is preferably formed at the end of the branch duct 25a.
[33] Furthermore, the cold air supply structure includes a rib 27 for fixing the door basket 14 to the inner surface of the door, and the door discharge port 26 is preferably formed in the rib 27.
[34] Hereinafter, the operation of the cold air supply structure of the refrigerator according to the present invention will be described.
[35] When the door D of the refrigerating compartment is closed as shown in FIG. 2, since the ceiling surface discharge port 23 and the door suction port 24 are opposed to each other, the cold air supplied from the supply duct 4 is the ceiling surface of the refrigerating compartment. Passed through the duct 22 and the ceiling surface discharge port 23 to the door intake port 24 formed on the upper surface of the door D, the cold air thus delivered is branched from the door duct 25 formed inside the door It is discharged toward the door basket 14 through the door discharge port 26 formed at the end of the branch duct 25a through the branch duct 25a.
[36] In addition, as shown in Figure 4, as the inner surface of the door (D), it is common that both ends of the door basket 14 is formed with a rib 27 for fixing it detachably, such a rib 27 When the door discharge port 26 is formed, the door discharge port 26 can be simply formed without adding a new configuration.
[37] Since the cold air supplied from the door discharge port 26 configured as described above is directly discharged toward the article stored in the door basket, the centralized cooling of the article stored in the refrigerating chamber is most possible.
[38] Thus, it is possible to achieve an even temperature distribution inside the refrigerating compartment in the most efficient way.
[39] On the other hand, when the door D of the refrigerating chamber is opened as shown in FIG. 3, the ceiling surface discharge port 23 and the door suction port 24 are released from the above-butted state, and thus, the ceiling surface discharge port 23 is provided. Cold air delivered to is discharged downward as it is.
[40] The cold air discharged as described above forms a so-called air curtain in the state in which the door D of the refrigerating chamber is opened, thereby preventing the cold air inside the refrigerating chamber from leaking to the outside.
[41] That is, the cold air supply structure according to the present invention as described above is configured to be able to change its role (air curtain, the cold air discharge of the door portion) according to the opening and closing of the door, without changing the structure by a separate device or the like, more efficient It is a cold air supply structure.
[42] In the above, the case in which the present invention is applied to the side-by-side type refrigerator has been described as an example, but is not necessarily limited thereto, and the basic technical idea of the present invention may be applied to other types of refrigerators.
[43] The present invention forms an air curtain when the door of the refrigerating chamber is opened to prevent the cooling air inside the refrigerating chamber to the outside, and in the state in which the door is closed, the most frequently drinked water or the like stored in the refrigerating chamber is stored. By intensively cooling the part of the door basket, a more advanced cold air supply structure of the refrigerator can be achieved in which even temperature distribution inside the refrigerating compartment can be achieved in a short time.
