As shown in fig. 1 and 2, in one embodiment, a refrigerator includes a cabinet 1 and a fresh storage container 2. A storage compartment is formed in the case 1. The fresh-keeping storage container 2 is arranged in the storage compartment. The storage compartments of a refrigerator are usually plural for realizing different functions. Such as a refrigerated storage compartment 11, a frozen storage compartment, a variable temperature storage compartment, and the like. The number and function of particular storage compartments may be configured according to the needs in advance. The cross-type side-by-side refrigerator shown in fig. 1 and 2 is merely an example, and one skilled in the art can configure the number, functions and layout of the specific storage compartments according to the needs.

The refrigerator of the embodiment is an air-cooled refrigerator. An air path system is arranged in the box body 1, cold air subjected to heat exchange by a heat exchanger (evaporator) is sent to the storage compartment through the box body air supply opening by a fan, and then returned to the air duct through the box body air return opening, so that circulating air refrigeration is realized. Since the refrigerator body, the door body and the refrigerating system of the refrigerator are all well known and easy to realize by those skilled in the art, the refrigerator body, the door body and the refrigerating system are not described in detail in order to not mask and obscure the utility model of the present application.

Fig. 2 shows an example of a fresh food storage compartment 11 in which a fresh food storage container 2 is disposed.

One or more fresh-keeping storage containers may be disposed in the refrigerator of the present embodiment. In some alternative embodiments, the fresh-keeping storage container can be arranged in one or more of the storage compartments, and long-time high-quality cold fresh preservation of food materials such as meat, fish and the like is realized through magnetic field and temperature regulation. For example, the fresh storage container may be disposed within any one of a refrigerated storage compartment, a frozen storage compartment, a temperature change storage compartment. For example, the fresh-keeping storage containers can be arranged in a plurality of the refrigerating storage compartments, the freezing storage compartments and the variable-temperature storage compartments at the same time, that is, the fresh-keeping storage containers are respectively arranged in a plurality of different storage compartments at the same time. For another example, a plurality of fresh-keeping storage containers can be simultaneously arranged in one storage compartment according to the requirement.

In other embodiments, the container may be disposed on the refrigerator door, preferably, on the inner side of the door when the container is small.

As shown in fig. 3 to 6, the fresh storage vessel includes a tub 100, a drawer 200, and at least one magnetic field assembly 300. The tub 100 includes an inner tub 110. The inner tub 110 is formed with a receiving compartment. The drawer 200 is drawably provided in the accommodating compartment 101, and the drawer 200 has a storage space 201. The magnetic field assembly 300 is disposed on at least one of a top side and a bottom side of the storage space 201, the magnetic field assembly 300 being configured to generate a magnetic field that acts within the storage space 201. An air supply duct 10 is formed at the left side wall of the inner tub 110 and/or the outside of the right side wall of the inner tub 110, and an air inlet 102 is formed at the rear end of the tub 100 to guide the cool air flow flowing in from the air inlet 102 from the rear to the front via the air supply duct 10.

As shown in fig. 3 to 6, in one embodiment, an air supply duct 10 is formed outside both left and right sidewalls of the inner tub 110. The tub 100 includes an inner tub 110 and an outer tub 120, the outer tub 120 is sleeved on the outer side of the inner tub 110, the air supply duct 10 is formed between the outer tub 120 and the inner tub 110, and the air inlet 102 is formed in the outer tub 120.

Specifically, the inner tub 110 has a box shape as a whole, and has a forward opening (i.e., an opening for accommodating the compartment 101). That is, the inner tub 110 has five sidewalls, i.e., a tub top sidewall, a tub bottom sidewall, a tub rear sidewall, a tub left sidewall, a tub right sidewall, which together enclose a receiving compartment 101 having an opening. The drawer 200 is drawably disposed inside the inner tub 110 through the opening of the accommodating compartment 101. Drawer 200 includes a bottom panel, a rear panel, a left panel, a right panel, and a front end panel 210. 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 inner tub 110 such that the inside of the inner tub 110 forms a closed storage environment, that is, such that the inner space of the drawer 200 is closed in the accommodating compartment 101, so that the drawer 200 and the inner tub 110 together define a fresh-keeping space. In a state that the drawer 200 is pulled out of the inner tub 110, an inner space of the drawer 200 is exposed to the outside, and objects to be stored can be taken and placed.

Referring to fig. 3 to 6, the outer case 120 also has five sidewalls, i.e., a top sidewall, a bottom sidewall, a rear sidewall, a left sidewall, and a right sidewall, and after the outer case 120 is sleeved outside the inner tub 110, the five sidewalls of the outer case 120 correspond to the five sidewalls of the inner tub 110. An air supply duct 10 is formed between the left side wall of the outer case 120 and the left side wall of the inner tub 110, and an air supply duct 10 is also formed between the right side wall of the outer case 120 and the right side wall of the inner tub 110. The air intake 102 is formed at a rear sidewall of the outer case 120. In addition, in a state in which the drawer 200 is in the closed position, the front end plate 210 of the drawer 200 does not seal the interval between the outer case 120 and the inner tub 110 from the front end.

Referring to fig. 3-6, further, the fresh storage vessel includes two magnetic field assemblies 300. Two magnetic field assemblies 300 are disposed on the top and bottom sides of the storage space 201, respectively. Specifically, the two magnetic field assemblies 300 are respectively disposed at the outer surface of the top sidewall of the inner tub 110 and the outer surface of the bottom sidewall of the inner tub 110. Specifically, the side wall of the inner tub 110 may be fixed by means of, for example, gluing, screw fixing, clamping, caulking, etc. By arranging the two magnetic field assemblies 300 on the top and bottom sides of the storage space 201 respectively, the magnetic fields in the storage space 201 can be distributed more uniformly. And the installation of the magnetic field assembly 300 can be facilitated by disposing the magnetic field assembly 300 outside the sidewall of the inner tub 110.

In the solution of the present embodiment, the air supply duct 10 is formed outside the left and right sidewalls of the inner tub 110, and the magnetic field assembly 300 is disposed at the top and bottom sidewalls of the storage space 201, that is, the magnetic field assembly 300 and the air supply duct 10 are located at different sides of the inner tub 110. Therefore, on the basis of realizing the effect of avoiding cold air from directly blowing food materials, the thicknesses of the air supply air path 10 and the magnetic field assembly 300 are not simultaneously added in the longitudinal direction of the fresh-keeping storage container, so that the problem that the utilization of the whole space of the refrigerator is influenced due to the fact that the size of the fresh-keeping storage container in the longitudinal direction is large is effectively avoided.

Referring to fig. 2, in particular, in the case where a general drawer is juxtaposed with a fresh-keeping storage container, if the fresh-keeping storage container is large in size in the longitudinal direction, a larger dead space exists in the longitudinal space of the juxtaposed drawers, which affects space utilization. Under the condition that the fresh-keeping storage container is placed independently, if the size of the fresh-keeping storage container in the longitudinal direction is large, the difference between the occupied space and the depth design size of the common storage space is large, and the separation design of the depth of the whole refrigerator compartment is influenced.

Further, by arranging the air supply passages 10 outside the left and right side walls of the inner tub 110, the cold air flow can flow through the left and right side walls of the inner tub 110 at the same time, and then the accommodating compartment 101 is cooled from the left and right side walls of the inner tub 110 at the same time, which is helpful to keep the left and right regions of the accommodating compartment 101 at substantially the same cooling rate, and thus is beneficial to improving the temperature uniformity of the accommodating compartment 101.

In other embodiments, the outer casing may be a casing that is only sleeved outside the side wall of the inner tub, where the air supply duct needs to be formed. Alternatively, in other embodiments, the outer case may not be provided, and the supply air path may be formed between the inner tub and the refrigerator compartment.

It should be noted that, in other embodiments, a magnetic field assembly may be disposed inside the sidewall of the inner tub, outside the sidewall of the inner tub, or may be fixed in the interlayer of the sidewall of the inner tub. Or can be arranged on the inner side of the bottom side wall of the drawer or can be arranged on the outer side of the bottom side wall of the drawer, and for example, the bottom side wall of the drawer is fixed on the side wall of the drawer in an adhesive mode, a screw fixing mode, a clamping mode, a caulking groove mode and the like. Or may be secured in the drawer bottom side wall interlayer. Alternatively, a cover plate can be arranged at the top opening of the drawer, and the magnetic field assembly is arranged on the cover plate, including the top or the bottom of the cover plate. Correspondingly, under the condition that two magnetic field assemblies are arranged, on the basis that the two magnetic field assemblies are ensured to be positioned on two opposite sides of the inner space of the drawer, each magnetic field assembly can be arranged at will according to the installation position.

As shown in fig. 3 to 7, the fresh-keeping storage container includes a drainage member 400, the drainage member 400 is formed with an air intake cavity 401, the drainage member 400 is provided with an air intake 402 and two air supply ports 403, the air intake 402 and the air supply ports 403 are both communicated with the air intake cavity 401, the air intake 402 is communicated with the air intake 102, and the two air supply ports 403 are respectively communicated with the two air supply air passages 10 so as to send the cold air flow entering the air intake cavity 401 from the air intake 402 into the two air supply air passages 10 through the two air supply ports 403.

Specifically, the drainage member 400 is disposed between the rear sidewalls of the outer case 120 and the inner tub 110, the air inlet 402 communicates with the air inlet 102, and the two air inlets 403 are respectively open to the rear ends of the two air supply paths 10. The cold air flow sequentially passes through the air inlet 102 and the air inlet 402 and enters the air inducing cavity 401, and the cold air flow entering the air inducing cavity 401 respectively enters the air supply air paths 10 outside the left side wall and the right side wall of the inner barrel 110 from the two air supply inlets 403.

By using the drainage piece 400 to guide air to the two air supply air paths 10, the barrel body 100 only needs to use one air inlet 102 for air intake, that is, the barrel body 100 only needs to realize the sealing connection between one air inlet 102 and the external air path, thereby being convenient for the butt joint of the barrel body 100 and the external air path.

In other embodiments, air inlets may be provided in the outer housing for the two air supply paths, respectively.

As shown in fig. 3 to 8, further, the magnetic field assembly 300 includes a magnetic source 310, and the magnetic source 310 is configured to generate a magnetic field. Specifically, the magnetic source member 310 is a permanent magnet sheet made of a ferrite magnetic powder and synthetic rubber composite material. The magnetic field assembly 300 further comprises a shim plate 320, the shim plate 320 being arranged on a side of the magnetic source 310 facing away from the storage space 201. By providing the magnetic source member 310 as a permanent magnet sheet, it is convenient to attach to the sidewall of the inner tub 110. By providing the shim plate 320, the shim plate 320 can guide the magnetic field of the magnetic source 310, so that the magnetic field is more uniformly distributed inside the drawer 200.

It should be noted that, in other embodiments, the magnetic source may be an electromagnetic coil, or the magnetic field assembly may be a separate permanent magnet sheet, or may be a separate electromagnetic coil, or the magnetic field assembly may be a structure formed by a permanent magnet sheet, an electromagnetic coil, and a magnetic plate.

As shown in fig. 3 to 9, further, the fresh-keeping storage container includes two magnetic conductive members 500, the two magnetic conductive members 500 are respectively located at the left side and the right side of the storage space 201, and two ends of each magnetic conductive member 500 are respectively connected with the magnetic homogenizing plates 320 of the two magnetic field assemblies 300, so as to form an annular magnetic field loop, which is beneficial to concentrating a magnetic field, improving the magnetic field utilization rate, playing a magnetic shielding role, and avoiding the influence of the magnetic field on surrounding devices.

As shown in fig. 3 to 9, further, the rear sidewall of the outer case 120 is further provided with an air return opening 103. The inner tub 110 is provided with at least one ventilation hole 111 formed in a sidewall for forming the supply air path 10, and the ventilation hole 111 communicates the supply air path 10 with the accommodating compartment 101 to introduce the cool air flow in the supply air path 10 into the accommodating compartment 101 through the ventilation hole 111. The rear sidewall of the inner tub 110 also forms a ventilation hole 112. During the flow of the cool air flow in the air supply passage 10, the cool air flow may enter the accommodating chamber 101 through the ventilation hole 111, and the cool air flow entering the accommodating chamber 101 may flow out from the ventilation hole 112. The location of the return air opening 103 is aligned with the vent 112 such that the air flow exiting the vent 112 can flow directly from the return air opening 103 out of the fresh storage vessel.

Further, all of the ventilation holes 111 are located at a height lower than the top end of the inner space of the drawer 200 in the longitudinal direction. That is, with the same longitudinal plane as the reference plane on which the drawer 200 and the ventilation holes 111 are projected, the projections of the ventilation holes 111 are located below the top edge of the projection of the drawer 200.

By providing the plurality of ventilation holes 111 on the inner tub 110 and the outer tub 120 corresponding to the side wall provided with the air inlet 102, the cold air flow entering the air supply duct 10 can enter the accommodating compartment 101 through the ventilation holes 111, thereby improving the refrigerating efficiency of the accommodating compartment 101. And the height position of the ventilation holes 111 in the longitudinal direction is lower than the top end of the inner space of the drawer 200, so that a great amount of cold air flow from the top opening of the drawer 200 to the inner space of the drawer 200 is prevented from causing cold air to directly blow food.

It should be noted that, in the case of small size of the ventilation hole, the position may be higher than the top of the inner space of the drawer. For example, in the case where the diameter of the ventilation holes is less than 3 mm.

In other embodiments, the air return opening may not be provided, and the cold air flow flowing out of the air vent may flow out of the front end of the tub through the space between the outer casing and the bottom side wall of the inner tub.
