Meanwhile, cold air flows in the air supply duct 10 and the air receiving space 20, so that cold air flowing out of an evaporator cavity of the refrigerator is prevented from being directly blown to food, and freezing caused by too low temperature of the food is effectively avoided.

In other embodiments, the air supply duct may be formed on the bottom sidewall of the tub. In addition, in other embodiments, the wind receiving space may be formed only at the left side walls of the outer case and the inner tub, or may be formed only between the right side walls of the outer case and the inner tub.

The magnetic homogenizing plate 320 is disposed at a side of the source magnetic member 310 facing away from the accommodating chamber 101, and is used for guiding the magnetic field generated by the source magnetic member 310, so as to improve the uniformity of magnetic field distribution. The source magnetic member 310 is a permanent magnetic sheet, and in particular, the permanent magnetic sheet may be made of a composite material of ferrite magnetic powder and synthetic rubber. The shim plate 320 is made of a magnetically conductive material, such as silicon steel. That is, for the magnetic field assembly 300 of the top side wall, the shim plate 320 is positioned above the source magnet 310 such that the shim plate 320 and the duct member 400 form the supply air duct 10.

It should be noted that, in other embodiments, the source magnetic member may be an electromagnetic coil. Or a structure formed by permanent magnet sheets and electromagnetic coils. Alternatively, in other embodiments, the magnetic field assembly may include only the source magnet.

As shown in fig. 1 to 8, further, the fresh storage vessel includes two magnetically permeable connectors 500. Two ends of the magnetic conductive connecting piece 500 are respectively connected with two magnetic homogenizing plates 320, and the two magnetic conductive connecting pieces 500 are arranged at two opposite sides of the storage space 201. Specifically, the two magnetically conductive connectors 500 are disposed outside the left and right sidewalls of the inner tub 120, respectively.

When the cool air flow enters the air receiving spaces 20 on both sides from the air supply duct 10, the cool air flow can be diffused into the accommodating compartment 101 through the air flow holes 104. The rear sidewall of the inner tub 120 is further provided with an air outlet 105, so that the cool air flow entering the accommodating compartment 101 flows out through the air outlet 105, and then can flow out of the tub 100 from the air return opening 103.

Because the wind force of the cold air flowing in the air supply duct 10 is weakened, and the wind direction is from top to bottom after entering the air receiving space 20, a plurality of air flow through holes 104 are formed on the side wall of the barrel body 100 provided with the air receiving space 20, so that the air flow enters the accommodating chamber 101 through the air flow through holes 104, the air flow entering the accommodating chamber 101 is not strong, the direct diffusion of the cold energy into the accommodating chamber 101 is realized while the direct blowing of food materials is avoided, and the refrigerating efficiency is improved.

Referring to fig. 10, since the magnetically conductive connector 500 is disposed on the sidewall of the inner tub 120, the plurality of air flow through holes 104 are respectively disposed at both front and rear sides of the magnetically conductive connector 500 to avoid the area covered by the magnetically conductive connector 500 and to facilitate uniform cooling in the front and rear directions of the accommodating compartment 101.

Referring to fig. 5, an opening 202 may be formed on a side wall of the drawer 200 to allow cold to be diffused into the storage space 201, thereby improving the cooling efficiency while avoiding direct blowing of food.

And, the area of the air supply port 401 of the air duct member 400 is larger, and accordingly, the air duct member 400 is provided with a plurality of air guide ribs so that the cool air uniformly flows out of the air supply port 401. Referring to fig. 11, the right side wall of the tub is formed with a return air inlet 103, and the air-receiving space 20 on the left side indirectly guides the air flow to the return air inlet 103 through an additional passage on the rear or bottom side of the tub 100.
