Problems solved by technology

However, there is no detailed description on how to prevent the dew condensation at the opening of the outlet through which the low-temperature cold air passes. The opening of the outlet is located at the two ends of the back, so there is still a possibility that the food will freeze when the food is placed at the end. (refer to Figure 11A )

Embodiment approach 1

[0057] figure 1 It is a front view of the refrigerator in Embodiment 1 of this invention. Such as figure 1 As shown, refrigerator 100 according to Embodiment 1 of the present invention is refrigerator 100 equipped with side-by-side doors, and a plurality of divided storage rooms are provided in heat insulating box 101 . The storage room is called a refrigerating room 102, an ice making room 105, a switching room 106, a vegetable room 104, a freezing room 103, etc. according to its function (cooling temperature).

[0058] A rotary insulating door 107 filled with a foam heat insulating material such as polyurethane is provided in the front opening of the refrigerator compartment 102 . In addition, in the ice making room 105, the switch room 106, the vegetable room 104, and the freezer room 103, heat insulating boards 108 as front plates of drawers are provided respectively, so that the storage rooms are sealed so that cold air does not leak out.

[0059] figure 2 It is a ...

Embodiment approach 2

[0147] As described above, Embodiment 1 has been described around making the temperature distribution of the refrigerator compartment uniform based on the positional relationship between the discharge port and the suction port (both the discharge port and the suction port are provided on the duct side).

[0148] However, as a method of making the temperature distribution of the refrigerating room uniform, it has been found through careful examination that the modified example has a certain effect in practical use, and it will be described below.

[0149] Embodiment 2 will be described below as a first modified example. Embodiment 2 of the present invention differs from Embodiment 1 in that instead of the right discharge ports 130e and 130f, the left discharge ports 130a and 130b are provided.

[0150] Figure 16 It is explanatory drawing of the duct with which the refrigerator in Embodiment 2 of this invention is equipped. Here, when the door of refrigerating room 102 is ope...

Embodiment approach 3

[0171] Next, Embodiment 3 will be described as a second modified example. Embodiment 3 of the present invention differs from Embodiment 1 in that the discharge ports 130a, 130b, 130e, and 130f are not provided on the side of the duct 129a, but are provided on the front of the duct 129a.

[0172] Figure 17 It is explanatory drawing of the duct with which the refrigerator in Embodiment 3 of this invention is equipped. Here, when the door of refrigerator compartment 102 is opened, the part visible from the front is shown. That is, the duct 129a is provided along the heat insulation box 101 of the refrigerating room 102 adopting the heat insulation structure, and a Y-shaped cold air circulation path is formed between the duct 129a and the heat insulation box 101 . Such as Figure 17 As shown by the arrows in the refrigerator compartment 102, the cold air in the refrigerator compartment 102 is sucked from the suction port 131a opened below the refrigerator compartment 102, circ...

Abstract

There is provided a refrigerator including a thermally insulated cabinet, a door body which is openably mounted to an opening portion of the thermally insulated cabinet, cooling means for cooling air within the thermally insulated cabinet to create cooled air, and a cooled-air circulation path for guiding cooled air between refrigerating room (1102) and the cooling means, wherein duct (1129a) which forms the cooled-air circulation path is formed to have a lateral width smaller than a lateral width of refrigerating room (1102) and, further, duct (1129a) includes, in its side surfaces, discharge ports (1130a to 1130f) for discharging cooled air into refrigerating room (1102) and suction port (1131a) for sucking cooled air from refrigerating room (1102). Further, chamber spaces (1302) are provided between the duct side surfaces and the inner side surfaces of the room, while there is no chamber space on the duct upper surface. This prevents the inconvenience of freeze of foods and the like in the refrigerating room, further improves the appearance of the refrigerating room and, further, maintains the uniformity of the temperature within the entire refrigerating room.

Description

technical field [0001] The present invention relates to a refrigerator, and more particularly to a refrigerator in which cool air circulates between a storage room and a cooling device. Background technique [0002] In recent years, it has been common for refrigerators to be arranged in such a way that a user puts storage items in the uppermost and frequently used refrigerator compartment that is easier to see, and a freezer compartment is disposed directly below the refrigerator compartment. In this case, the cooler is placed in the cooling room arranged at the back of the freezing room, so that the cold air is conveyed from the back of the cooling room to the back of the cooling room through ducts in order to supply the cold air to the entire refrigerating room. [0003] Figure 9 It is an explanatory drawing of the piping equipped in the conventional refrigerator. Here, when the door of refrigerating room 502 is opened, the part visible from the front is shown. That is,...
