As shown in fig. 1 to 3, in one embodiment, the fresh storage vessel includes a tub 100 and a drawer 200. The tub 100 defines a receiving compartment 101. The drawer 200 is drawably disposed in the accommodating compartment 101. An air supply duct 10 is formed in the top side wall of the tub 100, an air passing duct 20 is formed in the front end plate of the drawer 200, and an air return duct 30 is formed in the bottom side wall of the tub 100. The tub 100 is provided with an air inlet 102 and an air return 103, an air receiving opening 201 is formed at the top of a front end plate of the drawer 200, and an air outlet 202 is formed at the bottom. So that the air flow entering the air supply duct 10 from the air inlet 102 is guided to the air passing duct 20 through the air supply duct 10, and enters the air passing duct 20 through the air receiving opening 201. The air flow entering the air passage 20 from the air receiving opening 201 is guided to the return air passage 30 through the air passage 20, and enters the return air passage 30 through the air outlet 202. The air flow is guided to the air return opening 103 through the air return duct 30, and flows out of the tub 100 through the air return opening 103.

Referring to fig. 1 to 3, in particular, the tub 100 is box-shaped as a whole and has a forward opening (i.e., an opening of the accommodating compartment 101). That is, the tub 100 has five sidewalls, i.e., a tub top sidewall, a tub bottom sidewall, a tub rear sidewall, a tub left sidewall, and a tub right sidewall, which together enclose a receiving compartment 101 having an opening.

The drawer 200 is drawably disposed inside the tub 100 through an opening of the accommodating compartment 101. In a state in which the drawer 200 is in the closed position, the front end plate 210 of the drawer 200 may seal the opening of the tub 100 such that a closed storage environment is formed inside the tub 100, so that the drawer 200 and the tub 100 together define a fresh-keeping space such that food materials placed in the drawer 200 are sealed in the fresh-keeping space. In a state that the drawer 200 is pulled out of the tub 100, an inner space of the drawer 200 is exposed to the outside, and food materials can be taken and placed.

Further, the air inlet 102 is formed at the top end of the rear sidewall of the tub 100, and the air return 103 is formed at the bottom end of the rear sidewall of the tub 100. The air outlet 201 is formed at the top of the inner surface of the front end plate 210, and the air outlet 202 is formed at the bottom of the inner surface of the front end plate 210. In a state that the drawer 200 is at the closed position, the front end plate 210 of the drawer 200 covers the front end of the tub 100, and the position of the air receiving port 201 corresponds to the opening position of the front end of the air supply duct 10, and the air outlet 202 corresponds to the opening position of the front end of the return air duct 30.

Accordingly, in a state where the drawer 200 is in the closed position, cool air enters the rear end of the air supply duct 10 from the air inlet 102, then flows forward along the air supply duct 10, and enters the air passing duct 20 from the air receiving port 201 at the front end of the air supply duct 10. And then flows downwards along the air passing duct 20, and enters the return air duct 30 from the air outlet 202 at the bottom end of the air passing duct 20. Flows backwards along the return air duct 30, and flows out of the tub 100 from the air outlet 202 at the rear end of the return air duct 30.

In the solution of the present embodiment, by providing the air passing duct 20 at the front end plate 210 of the drawer 200, the air returning duct 30 is formed in the bottom sidewall of the tub 100, so that the cool air can flow in the air passing duct 20 and the air returning duct 30, thereby refrigerating the inner space of the drawer 200 from the front side and the bottom side of the drawer 200, and enabling the inner space of the drawer 200 to be smoothly reduced to the storage temperature. During the period, cold air is prevented from directly blowing the food materials, so that the food materials are prevented from being frozen out due to the fact that the temperature of the food materials is too low.

In addition, the air supply duct 10 is arranged on the top side wall of the barrel body 100, so that the air supply duct 10, the air passing duct 20 and the air return duct 30 form an air path structure surrounding the inner space of the drawer 200, and the cooling uniformity and the cooling efficiency of the inner space of the drawer 200 are improved.

It should be noted that, in other embodiments, the top side wall of the tub body is not provided with an air supply duct, and external cold air directly enters the air supply duct through the air receiving port of the air supply duct.

In other embodiments, the front end plate of the drawer may protrude a portion of the drawer to the inside of the drawer, and the protruding portion forms the air duct, that is, the top surface of the protruding portion forms the air inlet, and the bottom surface forms the air outlet.

The source magnetic unit 320 has a structure composed of a permanent magnet 321 and an electromagnetic coil 322. The permanent magnet sheet 321 is disposed at a side of the magnetic homogenizing plate 310 facing the accommodating compartment 101, and the electromagnetic coil 322 is disposed at a side of the permanent magnet sheet 321 facing the accommodating compartment 101.

For the magnetic field assembly 300 of the bottom side wall of the tub 100, the shim plate 310, the permanent magnet pieces 321, and the electromagnetic coil 322 are arranged in a stacked manner from bottom to top.

By providing the magnetic field assembly 300 in the sidewall of the tub 100, the magnetic field assembly 300 can generate a magnetic field in the accommodating compartment 101, thereby subjecting the food materials placed in the drawer 200 to the magnetic field. The magnetic field can play an auxiliary role in refrigerating and freezing of food materials, and can enable the food materials to be refrigerated below zero, namely, the food materials are not frozen below zero, so that the fresh-keeping effect of the food materials is improved. In addition, the cold air does not directly blow the food materials, so that the food materials are prevented from being frozen due to too low temperature. For freezing of food materials, the magnetic field can avoid large ice crystals generated when the food materials are frozen, the condition that cells of the food materials are punctured is reduced, and the juice loss of the food materials is reduced.

By providing the magnetic field assemblies 300 at opposite side walls of the tub 100, respectively, it is helpful to improve uniformity of distribution of the magnetic field in the accommodating compartment 101. Further, by providing the shim plate 310 and the source magnet 320, the shim plate 310 can guide the magnetic field generated by the source magnet 320, thereby further improving the uniformity of the magnetic field in the accommodating chamber 101.
