The direct-blowing air outlet 321 is used for directly blowing cold air to the middle part of the storage chamber 11 so as to directly blow the cold air to the food materials in the storage chamber 11, thereby rapidly refrigerating the food materials. The side-blowing air outlet 322 is used for blowing cold air to the side wall or the side portion of the storage chamber 11 to prevent the cold air from directly blowing the food material in the storage chamber 11, so as to prevent the cold air from taking away moisture on the food material.

With continued reference to fig. 4, 6, and 7, the number of the blow-through outlets 321 and the number of the side blow-through outlets 322 are plural, the blow-through outlets 321 are mainly distributed in the middle of the air duct cover plate 3, and the side blow-through outlets 322 are mainly distributed on the left and right sides of the air duct cover plate 3. Furthermore, those skilled in the art can also make appropriate adjustments to the distribution of the straight air outlet 321 and the side air outlets 322, for example, to make the side air outlets 322 distributed on the upper side of the duct cover 3.

Optionally, in order to avoid the blow-through outlet 321 from blowing the food material in the storage chamber 11, a wind shield (not shown) may be disposed at the blow-through outlet 321. Specifically, the wind screen is protruded from one surface of the cover plate body 31 near the storage chamber 11. Further alternatively, in order to slow down the wind speed at the side blow outlet 322, a grill (not shown) may be provided at the side blow outlet 322 to divide the airflow blown out from the side blow outlet 322 into a plurality of strands through the grill, thereby reducing the flow rate of a single airflow.

As shown in fig. 6 and 7, the intake vent 34 includes a blow-through intake vent 341 and a blow-on intake vent 342, wherein the blow-on intake vent 341 corresponds to the blow-on vent 321, and the blow-on intake vent 342 corresponds to the blow-on vent 322. Further, both the straight blow intake 341 and the side blow intake 342 are formed on the side wall of the intake chamber 33. Preferably, there are two direct-blowing air inlets 341 and two side-blowing air inlets 342, and the two direct-blowing air inlets 341 and the two side-blowing air inlets 342 are distributed in a quadrangular cross distribution. Specifically, two direct-blow air inlets 341 are oppositely disposed on the upper and lower sides of the air intake chamber 33, and two side-blow air inlets 342 are oppositely disposed on the left and right sides of the air intake chamber 33. Alternatively, one skilled in the art may set the two side blow inlets 342 and the straight blow inlets 341 in any other distribution manner as required, for example, set the straight blow inlets 341 to be one, set the side blow inlets 342 to be two, and make the one straight blow inlet 341 and the two side blow inlets 342 to be in a triangular distribution.

With continued reference to fig. 6 and 7, the cover plate air duct 35 includes a straight blowing air duct 351 and a side blowing air duct 352, wherein the straight blowing air duct 351 is respectively communicated with the straight blowing air outlet 321 and the straight blowing air inlet 341, and the side blowing air duct 352 is respectively communicated with the side blowing air outlet 322 and the side blowing air inlet 342.

The first damper 51 corresponds to one of the straight blow inlets 341 and one of the side blow inlets 342, and the second damper 52 corresponds to one of the straight blow inlets 341 and one of the side blow inlets 342. In other words, the first and second dampers 51 and 52 can be moved to the first position (shown in fig. 6) that opens the two through-blowing air inlets 341 and shields the two side-blowing air inlets 342, and the first and second dampers 51 and 52 can be moved to the second position (shown in fig. 7) that shields the two through-blowing air inlets 341 and opens the two side-blowing air inlets 342.

Further, although not shown in the drawings, in some embodiments of the present invention, the refrigerator further includes a temperature sensor for detecting the temperature of the storage chamber 11.

When the first and second dampers 51 and 52 are in the second position (as shown in fig. 7) and the temperature sensor detects that the temperature in the storage compartment 11 has risen to the second preset temperature, indicating that the temperature in the storage compartment 11 is high, rapid cooling is required, the motor 53 is reversed to move the first and second dampers 51 and 52 to the first position (as shown in fig. 6).

Wherein the first preset temperature is lower than the second preset temperature. For example, the first predetermined temperature is 2 ℃, 3 ℃, 5 ℃ or the like lower than the second predetermined temperature.
