Problems solved by technology

[0004] However, although it is an air duct provided in the heat insulator in an integrated refrigerator, in the case of a prefabricated refrigerator, the air duct connection part is exposed outside the heat insulator, so there is a possibility that cold air leaks from the air duct connection part, and from Concerns about heat leakage caused by heat conduction at the air duct connection
Also, if heat leaks from the air duct, condensation may occur due to the relationship between the temperature inside the box, the temperature of the outside air, and the humidity of the outside air.

Embodiment 1

[0031] use Figure 1 to Figure 9 The refrigerator of Embodiment 1 of the present invention will be described.

[0032] figure 1 It is a perspective view of the front of refrigerator 100 of this Example seen obliquely from upper right. As shown in the figure, the refrigerator 100 of this embodiment is a refrigerator in which the left main unit 1 and the right sub unit 1a can be connected at the connecting surface 4 of the main unit 1 and the connecting surface 4a of the sub unit 1a. also, figure 1 In the above, in order to arrange the main machine 1 and the child machine 1a in the left and right, the side surface is used as the connecting surface, but in the case of arranging the main machine 1 and the child machine 1a vertically, the upper and lower surfaces may be used as the connecting surface. In addition, the main machine 1 has a door 2 for taking out stored objects, and the slave machine 1a has a plurality of drawers 2a for taking out stored objects. The connection su...

Embodiment 2

[0074] Next, use Figure 10 A refrigerator 100 according to Embodiment 2 of the present invention will be described. In addition, overlapping descriptions of points common to Embodiment 1 are omitted.

[0075] Figure 10 It is a sectional view of the thermal bridge suppression part 60,60a in Example 2. As shown in the figure, the cross-sectional shape of the thermal bridge suppression parts 60, 60a of this embodiment is a shell structure with a plurality of bent parts, and the creepage distance is the same as that of the first embodiment. The shortest distance of the outer box opening edge 51 is long. In addition, the thermal bridge suppression parts 60 and 60a of this embodiment have the sandwich structure 61 sandwiched between the heat insulators 11 and 11a between the air duct exposure part 53 and the surface of the refrigerator 100 . This sandwich structure 61 is constituted by the fitting of a concave portion 62 and a convex portion 62a, wherein the concave portion 62...

Embodiment 3

[0079] Next, use Figure 11 A refrigerator 100 according to Embodiment 3 of the present invention will be described. In addition, overlapping descriptions of common points with the above-described embodiments are omitted.

[0080] Figure 11 It is a sectional view of the thermal bridge suppression part 70,70a in Example 3. In Embodiment 1 and Embodiment 2, the thermal bridge suppressors 56 , 60 and the like formed of resin materials and the like were used, but in this embodiment, the arrangement of such objects is omitted. That is, in the heat bridge suppression parts 70 and 70a of this embodiment, the heat insulators 11 and 11a are exposed between the air duct exposure part 53 and the surface of the refrigerator 100 . The space between the air duct exposed parts 53, 53a and the outer case opening edges 51, 51a is filled with air or a heat insulating material, and the heat conduction is relatively low. Since the heat insulating material is, for example, a foamed resin that...

Abstract

The present invention provides a refrigerator in which air passages of a main unit and a sub unit are communicated with each other, which suppresses heat leakage from the air duct connection portion toward the surface of the refrigerator, thereby suppressing dew condensation on the surface of the refrigerator. A refrigerator assembled by connecting and assembling the air duct exposed portion (53) of the main unit (1) and the air duct exposed portion (53a) of the slave unit (1a), wherein the main unit is provided with an outer box forming an outer contour, formed The inner box of the storage room, the heat insulator that suppresses the heat leakage from the inner box to the outer box, the cooler that generates cold air, and the air duct that circulates cold air from the cooler are provided on the above-mentioned sub-machine to form an outer contour. The outer box of the outer box, the inner box forming the storage room, the heat insulator that suppresses the heat leakage from the inner box to the outer box, and the air duct for circulating the cold air from the main unit, the main unit and the sub unit are in the air duct A thermal bridge suppressing portion having a creepage distance longer than a straight line distance from the exposed portion of the air duct to the outer case is provided between the exposed portion and the outer case.

Description

technical field [0001] The present invention relates to a refrigerator configured by connecting a main unit and a sub unit. Background technique [0002] In a general refrigerator, a cooler for generating cold air and an air duct for circulating the cold air are arranged in an insulator and integrated. Such an integrated refrigerator has increased external dimensions and weight along with increased capacity, and may not be able to be carried into a desired installation place due to interference with a carrying path, weight, and the like. [0003] Therefore, there has been proposed a refrigerator capable of being divided and assembled, which can be divided into a plurality of refrigerators, carried into a desired installation place, and then assembled. In such a refrigerator that can be divided and assembled, the refrigerator that can be divided into a main unit having a cooler and an air duct, and a sub unit having an air duct through which cold air from the main unit is se...
