[0015]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, there is provided a cold air passage provided on a back wall of a refrigerating chamber and extending up and down of the refrigerating chamber and having a cool air discharge port for discharging cold air into the refrigerating chamber; An interior light provided in a space between both side walls of the refrigerating chamber facing both side walls, and an interior light cover for covering the inside of the space where the interior light is installed. is there.

Then, the inside of the refrigerator is cooled by the cool air discharged through a plurality of cool air discharge ports provided in the upper part of the refrigerating chamber through the cool air passage provided in the back wall of the refrigerating chamber.

Since the interior light is arranged substantially at the center in the height direction of the refrigerating compartment and on the left and right sides between the side wall of the cold air passage and the side wall of the refrigerating compartment in the width direction, it reaches the corner of the refrigerating compartment space. Illuminate.

The inside lamp cover protects the inside lamp and shuts off the heat of the inside lamp from the refrigerating compartment.

Further, in a refrigerator provided with a cooler for the refrigeration cycle and a cold air supply duct for guiding the cool air cooled by the cooler into the refrigerating chamber, the refrigerator is branched from the cold air supplying duct in the left-right direction of the refrigerating chamber. A cold air passage provided on the back wall of the refrigerating compartment extending vertically above and below the refrigerating compartment and having a cool air discharge port for discharging cold air; and between both side walls of the refrigerating compartment facing both side walls of the cold air passage. The internal light provided in the space, the internal light cover that covers the inside of the space in which the internal light is installed, and the space between the inner sidewalls of the adjacent passages of the cold air passage are provided. Further, a cold air circulation duct for guiding a part of the cold air circulated in the refrigerating chamber from the cold air suction port to another cold air discharge port by the cool air circulation blower is provided.

A cold air supply duct that communicates between the cooler of the refrigeration cycle and the refrigerating compartment branches off to the left and right of the refrigerating compartment and extends to almost the entire height of the refrigerating compartment to provide a plurality of cold air passages. A plurality of cool air discharge ports are provided at desired positions in the passage.

Further, a part of the discharged cool air is guided to a suction port by a cool air circulation blower placed above a cool air circulation duct which is surrounded by a plurality of cool air passages and located substantially in the center of the refrigerating compartment. Will be led to another cold air discharge port provided at the position.

The in-compartment light is arranged in the central portion in the height direction of the refrigerating compartment, and in the width direction in the space portions on the left and right sides between the side wall of the cold air passage and the side wall of the refrigerating compartment.

Further, the inside lamp cover protects the inside lamp and shuts off the heat of the inside lamp from the refrigerating chamber.

Further, in a refrigerator provided with a cooler for a refrigeration cycle and a cold air supply duct for guiding the cool air cooled by the cooler into the refrigerating chamber, the back wall of the refrigerating chamber extends above and below the refrigerating chamber. A cool air passage provided with a cool air discharge port for discharging the cool air, and a passage adjacent to the cool air passage, and a part of the cool air circulating in the refrigerating chamber is separated from the cool air suction port by a cool air circulation blower to separate cool air. A cold air circulation duct leading to a discharge port, an inside light provided in a space between the side walls of the refrigerating chamber facing a side wall of the cold air circulation duct, and an inside of the space where the inside light is installed And an interior light cover for covering.

Then, the cool air is guided to the refrigerating compartment from a cool air supply duct which communicates between the cooler of the refrigeration cycle and the refrigerating compartment, and is discharged into the refrigerating compartment from the cold air discharge port provided in the cold air passage.

Further, a part of the discharged cool air is arranged at a position adjacent to each other on both sides of the cool air passage, and is sucked into a cool air circulation duct which merges in the upper part of the refrigerator. The blower for circulating cold air is provided in this merged duct and is guided to another cold air discharge port provided at a desired position.

Further, the interior light is arranged at the center in the height direction of the refrigerating compartment and on the left and right between the side wall of the cold air circulation duct and the side wall of the refrigerating compartment in the width direction to illuminate the interior of the refrigerator. Will be maintained.

Further, the space portion is provided over a plurality of stages of the shelves in the refrigerator. And since not only the part where the interior light is attached, but also the vertical direction of the refrigerating room and a large space is formed, the space where the interior light is installed dissipates heat widely and This will prevent the temperature from rising.

Further, an inside lamp cover is provided so as to extend over substantially the entire length of the space.

Since the interior light cover is attached to cover the space due to the lengthening of the space, the light emitted from the interior light travels through the space and goes through the interior light cover to the left and right in the refrigerating chamber. It will be irradiated from both sides.

Further, the space portion and the interior lamp cover are provided so as to extend to the top wall. Since the interior light cover communicates with the back of the refrigerator compartment and extends to the ceiling wall, the light emitted from the interior light goes to the lower part of the refrigerator interior via the interior light cover extending to the top surface. Will be irradiated.

Further, the space portion and the interior lamp cover are provided so as to extend to the back wall of the third temperature setting chamber provided in the lower portion of the refrigerating chamber.

In many cases, the top surface of the third temperature setting room is not transparent like the shelves in the refrigerating room, and the plate thickness of the top surface is thicker than the shelves in the refrigerator, so only the back wall of the refrigerating room is kept. There is an internal light, and even if it is covered with an internal light cover, the third
Irradiation to the temperature setting room was not at a bright level. Therefore, if the space portion and the interior lamp cover are extended to the back wall of the third temperature setting chamber, the above problems will be solved.

Further, a plurality of internal lamps are provided in the space. Then, by arranging a plurality of interior lights side by side in the vertical direction, the interior shelves are illuminated more uniformly.

Further, the deodorizing means is installed in the cold air circulation duct and is provided above the cold air suction port.

If a deodorizing means such as a low-temperature active catalyst deodorizing means is installed above the suction port formed in the cold air circulation duct, a part of the cool air discharged into the refrigerating compartment will enter this suction port again. When it circulates inside, it must pass through this deodorizing means, so that the odorous components in the room are forcibly circulated and adsorbed and oxidatively decomposed at low temperature to perform deodorizing action.
