Abstract

<P>PROBLEM TO BE SOLVED: To provide a refrigerator capable of securing the performance of an ice making chamber even in summer when a door of a freezing chamber is frequently opened and closed, keeping a vegetable chamber in high humidity, and improving the freshness of food stored in the vegetable chamber. <P>SOLUTION: A refrigeration chamber 2, the ice making chamber and a first freezing chamber are cooled by a first cooler 17, and only a second freezing chamber is cooled by a second cooler 22, thus the first cooler 17 cooling the ice making chamber can secure the performance of the ice making chamber without receiving influence, even when the door of the freezing chamber 5 is often opened and closed, and the warm moisture flows in the second freezing chamber in summer. Further as the vegetable chamber 6 is indirectly cooled by the heat transferred from the first freezing chamber without directly circulating the cold air in the vegetable chamber 6, the vegetable chamber 6 can be kept under high humidity, and the freshness of food such as vegetable stored in the vegetable chamber 6 can be improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI

  However, in the above conventional configuration, it is necessary to cover the cooling of the entire refrigerator body with a single cooler, and it is difficult to ensure cooling capacity particularly in an ice making room surrounded by a refrigeration room and a vegetable room with a high set temperature, Further, when the number of doors opened and closed in summer, a large amount of warm and humid air adheres to the cooler, so that the capacity of the cooler is greatly reduced, and the ice making speed is reduced. In addition, since cooling is performed by circulating cold air directly into the vegetable compartment, the humidity in the vegetable compartment decreases, and the freshness of foods such as vegetables stored in the vegetable compartment deteriorates.

  The present invention solves the above-mentioned conventional problems, and provides a refrigerator that secures the capacity of an ice making room and improves the freshness of foods such as vegetables stored in the vegetable room even in summer when door opening and closing increases. The purpose is to do.

  In order to solve the above-described conventional problems, a refrigerator according to the present invention includes a refrigerator main body, a refrigeration room for storing refrigerated food and the like in an upper part of the main body, and a first freezing room provided in a lower part of the refrigeration room. The ice-making room arranged in parallel to the first freezing room and the ice-making room for storing ice in the lower part of the refrigerating room, the second freezing room provided in the lower part of the refrigerator body, and the ice-making machine arranged in parallel A vegetable room for storing vegetables, a first cooler installed on the back of the refrigeration room, and the first cooling, provided between the room and the first freezing room and the second freezing room A refrigeration chamber discharge air passage for guiding cold air cooled by the cooler to the refrigerating chamber, a refrigerating chamber return air passage for returning the cold air that has cooled the refrigerating chamber to the first cooler, and the first cooling. An ice making chamber discharge air passage for guiding the cold air cooled by the container to the ice making chamber and the ice making chamber An ice making chamber return air path for returning the cool air that has cooled the chamber to the first cooler, and a first freezer chamber for guiding the cool air cooled by the first cooler to the first freezer A first freezer return air passage for returning the cool air that has cooled the discharge air passage and the first freezer compartment to the first cooler, and a second cooling device installed in the back of the second freezer compartment And the second freezer compartment discharge air passage for guiding the cool air cooled by the second cooler to the second freezer compartment and the cool air that has cooled the second freezer compartment to the second cooler A second freezer compartment return air passage for returning is provided, and the vegetable compartment is indirectly cooled using the cold air of the first freezer compartment return air passage.
