Refrigerated air supply apparatus for drawer type cold storage container of refrigerator

Abstract

This invention is a cold air providing component for fridge drawer type chilling box. It includes connecting opening, channel, box cover, air inlet opening, air outlet opening and flow adjusting device. The box cover is hollow structure. The air inlet opening, which is adjacent to connecting opening, is arranged on box cover. The air outlet openings are arranged on the lower plate of box cover ina line. The channel communicates to connecting opening and air inlet opening. The flow adjusting device includes handle, rotating bar, directing acting bar, baffling plate and locating plate. The center part of rotating bar is arranged on the rotating shaft. One end connects to handle and can rotate. The other end connects to directly acting bar and can rotate. The end part of this end is locatedby locating plate seriously. This invention can avoid cold air entering into other parts except the drawer type storage chamber. It can adjust the cold air provided to drawer type chilling box exactly.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a cold air supply mechanism for a drawer-type refrigerator used in a refrigerator. Background technique [0002] Generally speaking, a refrigerator can store food at a lower temperature, thereby preventing food spoilage and maintaining its freshness. A refrigerator generally includes: used to store food at a low temperature above freezing (usually 0~8°C) A refrigerator for storing food and a freezer for freezing and storing food at temperatures below freezing (usually -20 to -0°C). [0003] In recent years, in order to improve the space utilization rate of the refrigerator, people have developed a refrigerator in which the refrigerator compartment and the freezer compartment are horizontally arranged side by side. The horizontal side-by-side refrigerator with the refrigerating room and the freezing room is the same as the existing common refrigerator, and a wall-shaped partition is formed at th...

Problems solved by technology

In addition, the cold air flowing in through the communication port 40 collides with the wall of the drawer refrigerator 20 and scatters, thereby reducing the amount of cold air flowing to other parts of the drawer refrigerator 20, and using the reduced cold air Cooling other parts of the drawer refrigerator 20 will cause an existence between the side wall of the drawer refrigerator 20 that first contacts the cold air and the upper / lower wall and the front / rear wall of the drawer refrigerator 20. Due to this temperature difference, the meat food stored in the drawer refrigerator 20 cannot be cooled evenly.

[0021] In addition, for the cooling of meat food, the appropriate temperature for long-term storage of meat food is minus 1°C, while the moisture on the outer surface of meat food should be cooled to minus 7°C in order to utilize the heat produced by meat food. The surface ice prevents the moisture inside the meat food from evaporating; however, when the above-mentioned cooling method is adopted in the drawer-type refrigerator of the above-mentioned existing common refrigerator, the low-temperature cold air of about minus 7°C supplied through the communication port 40 cools the After the above-mentioned drawer refrigerator 20 side wall, in the process of flowing to other parts of the drawer refrigerator 20, the temperature of the cold air will rise and the amount of cold air will also decrease, which will make the other parts stored in the drawer refrigerator 20 side wall accessories. Partial meat food will not be cooled to minus 7°C, so that it cannot be stored properly for whole meat food

And after the air-conditioning around minus 7°C collides with the side wall of the drawer type refrigerator 20 and scatteres, it will cool down the beverages stored in the door basket on the inner side of the refrigerator door in front of the drawer type refrigerator 20 instead, making the beverages The food temperature is too cold for the user to drink
