Multilevel air way air outlet system of refrigerator

Abstract

The invention discloses a multilevel air way air outlet system of a refrigerator. The system comprises a freezing chamber, a refrigerating chamber and an evaporator cavity; an air way cover plate and a draught fan support are arranged on the back of the freezing chamber, a plurality of air outlets re formed in the air way cover plate, an air returning opening is formed in the lower portion of the air way cover plate, a fan motor is arranged on the draught fan support, an air guide ring is arranged on the draught fan support, one side of the air guide ring is communicated with the evaporator cavity, and the other side of the air guide ring is provided with an air splitting guide groove communicated with the air outlets and the refrigerating chamber, a second air supply hole is formed in the air way cover plate, the air way cover plate protrudes in the direction of the freezing chamber in a manner of surrounding the local part of the second air supply hole to form a side air guide opening, and an air blocking cover is arranged on the second air supply hole. Through design of combination of multiple air openings, the temperatures of all areas of the freezing chamber of the refrigerator can meet the low-temperature freezing and storage requirements.

Description

technical field [0001] The invention relates to the technical field of refrigerators, and more specifically relates to a multi-level air duct air outlet system of a refrigerator. Background technique [0002] Refrigerators can be divided into air-cooled refrigerators and direct-cooled refrigerators, wherein the air-cooled refrigerators transport the cooling capacity of the evaporator to the freezing chamber and the refrigerating chamber through a circulating air duct. At present, the air duct of the freezer is usually arranged at the back of the freezer, and the air duct cover plate is arranged on the back of the freezer compartment, and a plurality of air supply ports are arranged on the air duct cover plate, so that the air duct between the freezer compartment, the refrigerator compartment and the evaporator cavity is formed The circulating air duct is connected to the structure, and the fan makes the air circulate in the air duct forcibly, and sends the cold air to the fr...

AI Technical Summary

Problems solved by technology

This kind of air outlet conveys the cold air in the air duct to the mouth of the box, and the air supply space has certain limitations: it is difficult to take care of the temperature of each area of ​​the inner cavity with such an air outlet; if a high-speed air outlet is designed, let If the air is sent to the mouth of the box, the temperature of the area below the air outlet of the air duct cover will be relatively high; if the air supply outlet is designed with a medium and low speed, so that the temperature of the area below the air outlet of the air duct cover can meet the requirements of low-temperature frozen storage, then The temperature in the mouth area of ​​the freezer will be high
