Problems solved by technology
At this time, since the loss of cold air flow increases, the amount of cold air circulation decreases
In order to ensure a certain amount of cold air circulation, the number of blowers will be increased, or large-scale blowers will be used, which will easily lead to an increase in power consumption
[0010] These problems become obvious due to the difference in the cold air circulation structure caused by the arrangement of the refrigerator compartment, the freezer compartment, and the vegetable compartment. For the specific structure to solve these problems, there is no disclosure in Patent Document 1.

Embodiment Construction
[0038] Embodiments of the present invention will be described below using the drawings. Fig. 1 is an external perspective view of a refrigerator according to this embodiment. Refrigerator 1 is provided with a refrigerating compartment on the uppermost floor, and its front opening is closed by a rotating refrigerating compartment door 2 . Although the refrigerator compartment door 2 is a so-called side-by-side left and right door in FIG. 1 , it may also be a structure covered by a single door body.
[0039]In the lower part of the refrigerating room, an ice making room and a temperature switching room closed by pull-out doors 3 and 4 are arranged side by side. An automatic ice making device (not shown) is installed in the ice making chamber, and ice is stored in an ice storage container disposed under the ice making tray. Also, the ice can be taken out by pulling out the ice making compartment door 3 and pulling out the ice storage container together. The storage room adjace...

The present invention provides a refrigerator with excellent energy-saving property and using convenience. The invention fills heat insulation material between an outer case (11) and an inner case (10) to form a heat insulating space, and is provided with a refrigerating chamber (20) on the top layer of the heat insulating space. The refrigerator is provided with cold air passages (30L, 30R) arranged on the left and right sides on the back of the refrigerating chamber (20) and extending up and down, a shelf component (21) dividing the refrigerating chamber (20) into a plurality of accommodate spaces, a metal component (25) over the plurality of accommodate spaces and extending up and down, a cold air discharge opening (30a) for discharging cold air from the cold air passage (30) to the inside along the width direction, and an upper cold air discharge opening (30b) for discharging cold air to the upside from the cold air passage, therefore, the temperature homogenization in the refrigerating chamber (20) can also be realized even the space between two cold air passages is increased.
Description
technical field [0001] The present invention relates to refrigerators. Background technique [0002] Refrigerators with a refrigerator on the top shelf are widely used. Most of these refrigerators are medium-to-large-capacity refrigerators with more than three doors. For example, in Patent Document 1—Japanese Patent Application Laid-Open No. 2001-221554, it is disclosed that the refrigerator compartment is arranged on the uppermost floor together with the vegetable compartment and the freezer compartment. refrigerator. The refrigerator in Patent Document 1 includes a thermally conductive member covering a cold air duct at the rear of the refrigerator compartment, and the thermally conductive member becomes a part of the cold air duct to achieve moisturizing and temperature uniformity in the refrigerator compartment. In addition, aluminum alloy, stainless steel, or the like is used as the heat conductive member. [0003] The front of the refrigerator compartment is covered...
