Abstract

PROBLEM TO BE SOLVED: To prevent deterioration of peripheral plastic parts caused by the lamp heat by providing an in-chamber illuminating means covering a plurality of stages of in-chamber shelves and a cold air passage in which a cold air outlet is opened in a chamber in the vertical direction of a refrigerator chamber to perform flawless in-chamber illumination even when the internal capacity is large. SOLUTION: In a duct 13 for forming a cold air distribution passage, two gutter- shaped members are fixed to an inner surface of a partially cylindrical duct cover 16 separately in the right-to-left direction. Right and left edge parts of the duct cover 16 are inserted into two ribs provided in the longitudinal direction with the prescribed intervals to an end in the center of a main refrigerator chamber to form two cold air distribution passages in the longitudinal direction covering approximately whole height. An in-chamber lamp 17 is installed in a longitudinal space between two gutter- shaped members fixed to the inner surface of the duct cover 16, and covered by a lamp cover 18. Cold air outlets 22a, 22b, 23a, 23b, 24a, 24b are provided at the prescribed positions of the duct cover 16. Flawless illumination can be made to every corner of the wide refrigerator chamber, and deterioration of peripheral plastic parts caused by the heat generated when the in-chamber lamp 17 is lit can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a cooling and storage room lighting refrigerated chamber.

[0002]

2. Description of the Related Art The refrigerating compartment of a large refrigerator tends to have a remarkably large internal volume. However, if the refrigerating compartment exceeds a certain limit, the refrigerating compartment may be evenly distributed by a simple cold air passage as in the past. Cooling is not possible, and some drastic measures are required. In addition, when the internal volume of the refrigerator compartment becomes large, it becomes difficult to evenly illuminate the interior of the compartment only with the interior light installed in one corner, and there is a problem that it is inconvenient for food to enter and exit especially when the room is dark. Occur.

[0003]

On the other hand, in addition to the main refrigerator compartment, a vegetable compartment, a chilled compartment,
A multi-door refrigerator having a sub-refrigerator such as a bottle room is becoming widespread. In the case of this type of refrigerator, it is necessary to distribute cold air to the sub-refrigerator in addition to the main refrigerator. FIGS. 6A and 6B show an example of a cold air distribution system in the case of a multi-door refrigerator (see Japanese Utility Model Application Laid-Open No. 63-125767). In this example, the cool air from the cooler room is divided into a plurality of cool air distribution passages, and is distributed to each of the refrigerator compartments via the passages. Each distribution passage is provided with a flow controller (for example, a control valve or a control plate such as a damper thermometer), and these flow controllers are individually controlled by the output of a temperature detector provided in each refrigerator compartment. Is done.
