Detailed Description

Referring to fig. 1, the invention provides an air duct structure of a refrigerator temperature changing chamber, which comprises a temperature changing chamber 1 and a drawer 2 accommodated in the temperature changing chamber 1, wherein a supply-air outlet 3 is arranged on the rear wall of the temperature changing chamber 1, a gap 4 is formed between the left side wall and the right side wall of the drawer 2 and the temperature changing chamber 1, in order to solve the technical problems in the background art, the technical scheme of the invention is that a closed cooling circulation channel is formed between the supply-air outlet 3 and the gap 4, a temperature changing air duct cover plate 5 is adapted to an opening above the drawer 2, and the air supplied by the supply-air outlet 3 is divided by the temperature changing air duct cover plate 5 from the gap 4 between the left side wall and the right side wall of the drawer 2 and the temperature changing chamber 1.

The principle is as follows: the cover plate 5 of the temperature-changing air channel is used for blowing the air from the air supply outlet 3 to the two sides of the drawer 2 instead of directly blowing the air into the drawer, so that the temperature-changing chamber has the following three functions: 1. the temperature is adjustable: the blowing time at the air supply outlet 3 can be controlled through the air door, so that the aim of changing the temperature of the temperature changing chamber is fulfilled; 2. and (3) moisturizing: wind does not directly blow into the drawer 2, so that moisture on food cannot be brought away by the wind, and the moisture preservation of the food is realized; 3. and (3) temperature is uniform: the temperature of the enclosed space around the drawer is reduced firstly, so that the space inside the drawer is cooled, and the cold airflow is not blocked by the articles in the drawer, so that the uniformity of the temperature inside the drawer is ensured.

In this embodiment, referring to fig. 2, the cover plate 5 of the variable temperature air duct includes an upper cover plate 51 and a lower cover plate 52 which are embedded with each other, and referring to fig. 3, an air guide rail 53 made of EPS material is provided between the upper cover plate 51 and the lower cover plate 52 and extends towards the left and right sides, an air duct is formed between the air guide rail 53 and the lower cover plate 52, and the air duct is communicated with the gap 4 between the left and right side walls of the drawer 2 and the variable temperature chamber 1. By adopting the design of the combined cover plate, the air quantity can be well distributed, and the air can be effectively prevented from directly blowing into the drawer, so that the food humidity in the drawer is ensured.

In this embodiment, referring to fig. 3, the number of the air guide tracks 53 is four, and the air guide tracks include a first guide track air duct 531 and a second guide track air duct 532 extending toward the freezer compartment of the refrigerator, and a third guide track air duct 533 and a fourth guide track air duct 534 extending toward the outside of the refrigerator, where the first guide track air duct 531 and the third guide track air duct 533 are close to the air supply outlet 3, and the second guide track air duct 532 and the fourth guide track air duct 534 are away from the air supply outlet 3, where the air volume toward the third guide track air duct 533 and the fourth guide track air duct 534 is twice the air volume toward the first guide track air duct 531 and the second guide track air duct 532, and the air volume toward the fourth guide track air duct 534 is twice the air volume toward the second guide track air duct 532 and the third guide track air duct 533 and four times the air volume toward the first guide track air duct 531. The reason is that the temperature of the temperature-varying chamber 1 facing the freezing chamber side is low, and the temperature of the temperature-varying chamber 1 facing the outside of the refrigerator is high, so that the amount of air in the temperature-varying chamber facing the outside of the refrigerator needs to be larger than that in the freezing chamber side; and because the air supply outlet 3 is arranged on the rear wall of the temperature-changing chamber 1, the air can firstly pass behind the temperature-changing chamber 1, and in order to ensure that the air quantity distributed by the front air inlet and the rear air inlet has little difference, the air quantity in front of the temperature-changing chamber needs to be increased, thereby ensuring the temperature uniformity in the whole temperature-changing chamber.

In the present embodiment, referring to fig. 4, the bottom center of the drawer 2 is provided with a return hole 21, and the return hole 21 makes the air supply opening 3, the gap 4 and the drawer 2 form a closed cooling circulation channel. The arrangement of the air return hole 21 can enable the cold air to form cold air circulation inside the drawer, and the cooling effect is improved.

In this embodiment, referring to fig. 5, a refrigerating air duct 6 connected to a refrigerating chamber (not shown) is disposed behind the variable temperature chamber 1, an air inlet of the refrigerating air duct 6 is connected to an air supply outlet of the freezing chamber, and supplies air into the variable temperature chamber 1 through the air supply outlet 3, the refrigerating air duct 6 guides the air in the freezing chamber to the refrigerating chamber and the variable temperature chamber for refrigeration, and an air door 7 is disposed at a position of the refrigerating air duct 6 close to the air supply outlet of the freezing chamber. The air door 7 can adjust the air inlet quantity according to the refrigeration requirement, thereby controlling the temperature of the refrigerating chamber and the temperature changing chamber.

In this embodiment, the air door 7 is a sub-sub air door, and the air entering the refrigerating chamber and the temperature-variable chamber is distributed through the sub-sub air door. The design of the primary and secondary air doors can accurately control the air volume entering the refrigerating chamber and the temperature-changing chamber, so that the temperatures of the refrigerating chamber and the temperature-changing chamber can be conveniently and correspondingly adjusted.

In this embodiment, referring to fig. 6, the cooling air duct 6 is provided with an air guiding step 61 in an inclined plane shape along the height direction. By the arrangement of the air guide steps 61, air entering from the air inlet can flow upwards (the refrigerating chamber) as much as possible, and the refrigerating effect of the refrigerating chamber is ensured.

In this embodiment, referring to fig. 7, a water outlet 8 is provided at the air door 7 of the refrigerating duct 6. By utilizing the design of the water outlet 8, water accumulation can be effectively prevented, and stable operation is ensured.

The invention also provides a refrigerator which comprises the temperature-changing chamber provided with the air duct structure of the temperature-changing chamber of the refrigerator.
