  In a refrigerator having a freezer compartment in the middle of the top and bottom of the refrigerator, in order to increase the cooling efficiency, even if two coolers for the refrigerated temperature zone and the freezer temperature zone are used, the cold air is circulated in each room. Can do.

  The present invention is provided in the refrigerator center disposed at the uppermost part of the refrigerator, the vegetable room disposed at the lowermost part, the freezing room disposed between the refrigerator room and the vegetable room, and the rear center upper part of the refrigerator room. A first cooler for the refrigerated temperature zone, a first fan for circulating the cool air from the first cooler to the refrigerated compartment and the vegetable compartment, and a refrigeration provided below the rear center of the freezer compartment A second cooler for the temperature zone chamber, a second fan for circulating cold air from the first cooler to the freezer compartment, cold air supply ducts provided on the left and right of the rear of the refrigerator compartment, A cold air supply duct for a vegetable room that is provided laterally behind the freezer compartment, is connected to one of the left and right cold air supply ducts, and supplies cold air to the vegetable compartment, and behind the freezer compartment, and Provided on the side opposite to the vegetable room cold air supply duct, from the vegetable room A vegetable room cold air return duct that returns the cold air to the rear of the refrigerator compartment, a cold air return from the vegetable room cold air return duct, and a return duct that returns the cold air returned from the refrigerator compartment to the first cooler. A refrigerator characterized by.

A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view of the refrigerator 1 with all doors removed. FIG. 2 is a front view of a refrigerator in which the duct cover plate at the back of the refrigerator is removed to expose the duct portion in order to explain the circulation of cold air. FIG. 3 is a longitudinal sectional view.
In FIG. 1, in the refrigerator 1, 2 is a refrigerator compartment, 3, 4 and 5 are freezer compartments, and 6 is a vegetable compartment. Of the freezing rooms 3, 4 and 5, 3 is an ice making room, 4 is a small freezing room, and 5 is a large freezing room. 7 and 8 are heat insulation partitions, and 9 is a front partition.

  BR and BF are cold air inlets.

  In FIG. 2, 2 is the refrigerator compartment arrange | positioned at the uppermost part of a refrigerator. 6 is a vegetable room arranged at the bottom. Reference numerals 3, 4, and 5 are freezing rooms arranged between the refrigerator compartment 2 and the vegetable compartment 6.

  Reference numeral 10 denotes a first cooler for a refrigerating temperature zone chamber provided at the upper center of the rear portion of the refrigerating chamber 2. The Reference numeral 11 denotes a first fan for circulating cold air from the first cooler 1 to the refrigerator compartment 2 and the vegetable compartment 6.

  Reference numeral 12 denotes a second cooler for a freezing temperature zone chamber provided below the rear center of the freezing chambers 3, 4, and 5. Reference numeral 13 denotes a second fan for circulating the cool air from the first cooler 12 to the freezer compartments 3, 4, and 5.

  Reference numerals 14 and 15 denote cold air supply ducts provided on the left and right of the rear part of the refrigerator compartment 2. The cold air supply duct 15 on the left side is stopped midway without extending to the lower end of the refrigerator compartment 2.

  16 is provided on the right side behind the freezer compartments 3, 4, 5, and is connected to the right one 14 of the left and right cold air supply ducts 14, 15 to supply the cold air to the vegetables 6. Supply duct.

  17 is provided behind the freezer compartments 3, 4, and 5 and on the left side opposite to the vegetable compartment cold air supply duct 16, and the return cold air from the vegetable compartment 6 is placed behind the refrigerator compartment 2. The vegetable room cold air return duct returns to the lower side of the stopped portion of the left cold air supply duct 15.

Reference numeral 18 denotes a return duct that returns the return cold air from the vegetable room cold air return duct 17 and the return cold air from the return port of the refrigerator compartment 2 (see BR in FIG. 1) to the first cooler 10.
Thus, according to the first embodiment, in the refrigerator in which the freezer compartment is arranged in the middle of the top and bottom of the refrigerator, in order to increase the cooling efficiency, two coolers for the refrigerated temperature zone chamber and the freezer temperature zone chamber are provided. Even if it is used, it is possible to efficiently circulate cold air to each chamber.

It is the front view which removed the door of the refrigerator of Example 1. FIG. It is the front view which removed the duct cover of Example 1. FIG. 1 is a longitudinal sectional view of Example 1. FIG.
