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. Other storage drawers can be arranged in the refrigerating storage compartment 11 besides the fresh-keeping storage container 2, for example, fig. 2 shows an example of the fresh-keeping storage container 2, and the refrigerating storage compartment 11 is also provided with other three drawer-type storage containers, wherein one drawer-type storage container is transversely arranged in parallel with the fresh-keeping storage container 2.

The plurality of storage compartments can be spatially divided in a rack, a shelf, a drawer and the like, so that corresponding storage functions, such as freezing, drying storage and the like, are realized. 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.

Referring to fig. 3 to 5, the fresh storage container 2 includes a tub 100, a drawer 200, a first magnetic field device 300, and a second magnetic field device 400. The tub 100 includes an inner tub 110 and an outer tub 120, and the inner tub 110 is formed with a receiving compartment 101. The outer case 120 is sleeved outside the inner tub 110. The drawer 200 is drawably disposed in the accommodating compartment 101. The first and second magnetic field devices 300 and 400 are used to generate a magnetic field inside the drawer 200, and the first and second magnetic field devices 300 and 400 are disposed at opposite sides of the drawer 200, respectively.

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.

The side wall of the outer case 120 may be formed separately or may be formed by the inner wall of the refrigerator compartment.

Referring to fig. 3 to 6, the first magnetic field device 300 is disposed at the top opening of the drawer 200, and the first magnetic field device 300 covers the top opening of the drawer 200. The second magnetic field device 400 is provided at a bottom sidewall of the drawer 200. Specifically, when the drawer 200 is in the closed position, the first magnetic field device 300 covers the top opening of the drawer 200, that is, the first magnetic field device 300 and the side wall of the drawer 200 together define a relatively closed space within the interior space of the drawer 200.

In the solution of the present embodiment, by disposing the drawer 200 in the accommodating compartment 101 of the inner tub 110 and disposing the first magnetic field device 300 and the second magnetic field device 400 on opposite sides of the drawer 200, respectively, the first magnetic field device 300 and the second magnetic field device 400 are close to the inner space of the drawer 200, and then the region where the magnetic field lines generated by the first magnetic field device 300 and the second magnetic field device 400 are most dense is located in the inner space of the drawer 200, so that the magnetic field in the inner space of the drawer 200 is more uniform, because if the magnetic field source is further from the drawer, the magnetic field acting in the drawer is more divergent (the magnetic field lines are more sparse), resulting in insufficient uniformity of the magnetic field in the drawer. Moreover, the first magnetic field device 300 and the second magnetic field device 400 are oppositely arranged, so that the region with more concentrated magnetic field lines of one magnetic field device is complementary to the region with more sparse magnetic field lines of the other magnetic field device, and the uniformity of the magnetic field inside the drawer 200 is further improved. And the first magnetic field device 300 and the second magnetic field device 400 are closely attached to the drawer so that the amount of magnetism of the magnetic field devices can be relatively reduced on the basis of ensuring the intensity of the magnetic field in the inner space of the drawer 200, thereby reducing the cost. In addition, the drawer 200 is positioned in the relatively closed accommodating compartment 101 of the tub 100 to shield a magnetic field to some extent.

Further, by arranging the first magnetic field device 300 at the top opening of the drawer 200 to cover the top opening of the drawer 200, the second magnetic field device 400 is arranged on the bottom side wall of the drawer 200, so that the first magnetic field device 300 and the side wall of the drawer 200 enclose the inner space of the drawer 200 into a relatively closed space together, and cold air is not easy to directly enter the drawer 200, so that food is not directly blown under the condition that the cold air is blown into the accommodating compartment 101 at will, the temperature of the food is prevented from being too low, and the storage effect is guaranteed. And the relatively closed space of the drawer 200 is located in the relatively closed receiving compartment 101 of the tub 100, helping to maintain the storage temperature and thus the storage effect of the food materials.

It should be noted that, in other embodiments, the first magnetic field device and the second magnetic field device may also be that the first magnetic field device is disposed on the left side wall of the drawer and the second magnetic field device is disposed on the right side wall of the drawer. Alternatively, the first magnetic field device is disposed on a front side wall of the drawer, and the second magnetic field device is disposed on a rear side wall of the drawer.

Referring to fig. 3 to 6, further, a first air flow path 10 is formed outside the top sidewall of the inner tub 110, and the first air flow path 10 is used to directly or indirectly guide the cool air flow from the outside of the inner tub 110 to the accommodating compartment 101. And the first air flow path 10 is used to guide the cool air flow from the rear to the front. Specifically, an interlayer space is formed between the top wall of the outer case 120 and the top wall of the inner tub 110, and the first air flow path 10 is formed in the interlayer space. That is, there is a space, i.e., a sandwich space, between the top wall of the outer case 120 and the top wall of the inner tub 110, in which the first air flow path 10 is formed.

The duct wall of the first air flow passage may be formed by the outer case and the inner tub, or other members such as a heat insulating plate may be provided in the interlayer space, and the duct wall of the first air flow passage may be formed by the other members.

Further, an air inlet 102 is formed at the rear side of the top wall of the outer casing 120, and cold air flow outside the tub 100 enters the first air flow path 10 through the air inlet 102. Such that the first air flow path 10 directs the cool air flow from back to front.

As shown in fig. 3 to 7, the front end plate 210 of the drawer 200 is formed with a second airflow path 20, the top end of the second airflow path 20 is provided with an air receiving hole 201, the front end of the first airflow path 10 is provided with a blowing hole 103 to guide the cool air flowing toward the second airflow path 20 through the first airflow path 10, and the cool air sequentially passes through the blowing hole 103 and the air receiving hole 201 to enter the second airflow path 20.

Specifically, the front end panel 210 of the drawer 200 includes a panel 211 and an end panel hood 212. An end plate fan housing 212 is provided inside the panel 211, the end plate fan housing 212 defining the second airflow passage 20, and a wind receiving hole 201 is formed at a top end of the end plate fan housing 212. The end plate wind housing 212 protrudes from the panel 211 toward the inside of the drawer 200, and the left, right, and bottom sidewalls of the end plate wind housing 212 are all located inside the sidewalls of the drawer 200. The air receiving hole 201 is formed at a top sidewall of the end plate fan housing 212.

The second airflow path may be defined by the end plate cover and the panel together, or may be formed by the end plate cover alone (that is, the end plate cover has a side wall that is bonded to the inner surface of the panel). In addition, the end plate fan cover can be a part which is formed separately and then assembled on the drawer, or can be a part which is formed integrally with the drawer. And, the left side wall, the right side wall and the bottom side wall of the end plate fan housing can be directly formed by the left side wall, the right side wall and the bottom side wall of the drawer.

As shown in connection with fig. 6 to 9, wherein the fresh-keeping storage vessel further includes an end plate fitting 130, the end plate fitting 130 being provided at the front end of the tub 100, surrounding the opening of the accommodating compartment 101 and assembled with the outer case 120 and the inner tub 110, thereby closing the first air flow path 10. Meanwhile, the air supply hole 103 is formed in the end plate fitting 130 so that the air flow in the first air flow path 10 can flow out of the air supply hole 103.

It should be noted that, in other embodiments, the fresh-keeping container may not be provided with the end plate matching member. In this case, the air-blowing hole may be formed in a portion of the outer case bent from the front end of the outer case toward the tub liner, or in a portion of the inner case bent from the front end of the inner case toward the tub outer case.

It should be noted that, in other embodiments, when the fresh storage vessel includes only the inner tub, the air-sending hole may be formed by an additional member that forms the first air flow path.

As shown in fig. 6 and 7, the plane of the outlet of the air supply hole 103 is inclined toward the top of the fresh food storage container in a direction away from the rear end of the fresh food storage container. The plane in which the inlet of the air-receiving hole 201 is located is inclined toward the bottom of the drawer 200 in a direction away from the panel 211.

Specifically, the portion of the end plate mating member 130 for forming the air-sending hole 103 is inclined toward the top of the fresh food storage container in a direction away from the rear end of the fresh food storage container, that is, toward the top of the fresh food storage container in a direction toward the opening of the inner tub 110. The plane in which the outlet of the air-sending hole 103 is located, i.e. the plane in which the bottom side of the portion is located, i.e. the plane in which the side facing away from the first air flow path 10 is located.

The top side wall of the end plate wind housing 212 is inclined toward the bottom of the drawer 200 in a direction away from the panel 211, that is, toward the bottom of the drawer 200 in a direction in which the front end of the drawer 200 is directed toward the rear end. The plane in which the inlet of the air receiving hole 201 is located, i.e., the plane in which the top end face of the end plate fan housing 212 is located, i.e., the plane in which the top side wall of the end plate fan housing 212 is located away from the side face of the second airflow passage 20.

As shown in fig. 6 and 7, the plane of the outlet of the air supply hole 103 and the plane of the inlet of the air receiving hole 201 are identical in inclination direction from the front to the back of the fresh food storage container.

By tilting the plane of the outlet of the air supply hole 103 in a direction away from the rear end of the fresh food storage container toward the top of the fresh food storage container, the plane of the inlet of the air receiving hole 201 is tilted in a direction away from the panel 211 toward the bottom of the drawer 200. In the process of enabling the cold air to enter the second airflow passage 20 from the first airflow passage 10, the flowing route of the cold air is in a parabolic shape on the whole, so that the cold air flows between the air supply hole 103 and the air receiving hole 201 more smoothly, and the air leakage is reduced. In addition, the beveled top of the end plate fan housing 212 also helps to reduce the probability of foreign objects falling into the second airflow path 20.

As shown in fig. 6 to 10, the bottom of the end plate fan housing 212 is provided with an air outlet 202 to guide the cool air flow in the second air flow path 20 between the bottom of the drawer 200 and the inner tub 110 indirectly or directly through the air outlet 202. The bottom side wall of the end plate fan housing 212 is provided with four air outlet holes 202. Corresponding through holes are also formed in the bottom side wall of the drawer 200, so that the air flow in the second air flow path 20 flows out from the air outlet 202, flows between the bottom of the drawer 200 and the inner tub 110 through the through holes in the bottom side wall of the drawer 200.

It should be noted that, in other embodiments, the end plate fan housing may also be provided with an air outlet, for example, an elongated air outlet extending in the left-right direction. Two, three or five equal numbers of air outlets may also be provided.

Referring to fig. 3 to 11, specifically, the rear end of the top side wall of the outer casing 120 is provided with an air return port 104, and the air return port 104 is arranged in parallel with the air inlet 102. The rear sidewall of the inner tub 110 forms an air outlet 105, and a longitudinally extending air outlet duct (not shown) is formed between the rear sidewall of the inner tub 110 and the rear sidewall of the outer tub 120, and the top end of the air outlet duct is communicated with the return air inlet 104. The cold air flows to the rear end of the drawer 200 along the bottom of the drawer 200, then flows upwards to the air passing hole 105, flows into the air passing channel from the air passing hole 105, then flows to the air return opening 104 along the air passing channel, and finally flows out from the air return opening 104.

In summary, the air path inside the fresh-keeping storage container is configured to: the air flow enters the rear end of the first air flow path 10 from the air inlet 102, and then flows through the first air flow path 10 from the rear to the front. At the front end of the first air flow path 10, air flows through the air supply hole 103 and the air receiving hole 201 into the top end of the second air flow path 20 defined in the front end plate 210 of the drawer 200, and then flows through the second air flow path 20 from top to bottom. At the bottom end of the second air flow path 20, air flows between the bottom plate of the drawer 200 and the bottom wall of the inner tub 110, and then flows from front to rear. At the connection position of the rear end of the bottom plate of the drawer 200 and the rear plate of the drawer 200, the air flow enters the gap between the rear plate of the drawer 200 and the rear wall of the inner tub 110. Then flows into the air passage from the air passage 105, and the air flow finally reaches the air return opening 104 along the air passage.

The internal air path of the fresh-keeping storage container surrounds the whole fresh-keeping storage container for a circle, and can realize sufficient heat exchange under the condition that the fresh-keeping storage space is not in direct contact with stored objects, so that the fresh-keeping storage container is uniformly refrigerated and cooled.

As shown in conjunction with fig. 3 to 11, the top sidewall of the inner tub 110 is formed with a plurality of ventilation holes 111 such that the cool air flow flowing in the first air flow path 10 partially flows into the accommodating compartment 101 through the ventilation holes 111. Specifically, the top side wall of the inner tub 110 constitutes a bottom duct wall of the first air flow path 10, and the top side wall of the inner tub 110 is formed with a plurality of ventilation holes 111. The cool air flow entering the first air flow path 10 from the air inlet 102 flows from the rear to the front, and part of the cool air passes through the top measuring wall of the inner tub 110 through the air vent 111 during the flowing process, so as to flow into the accommodating compartment 101, that is, the first air flow path 10 directs the cool air flow from the outside of the inner tub 110 directly to the accommodating compartment 101.

By providing the first air flow path 10 on the top side wall of the inner tub 110 and providing the vent 111 on the top side wall of the inner tub 110, the first air flow path 10 can guide the cool air flow from back to front and enable a part of the cool air flow to flow into the accommodating compartment 101 via the vent 111 during the back-to-front flow in the first air flow path 10. Since the main direction of the cold air flow in the first air flow path 10 is to flow from the rear to the front and the ventilation hole 111 is to be directed longitudinally, a proper amount of cold air flow is caused to flow smoothly from the ventilation hole 111 into the accommodating compartment 101, thereby contributing to a smooth decrease in temperature in the accommodating compartment 101 while improving the cooling efficiency.

In other embodiments, the number of the ventilation holes may be one, and the ventilation holes may be arranged in an elongated air hole extending in the front-rear direction. In addition, the shape of the vent hole may be any shape.

That is, the side of the fitting plate facing the drawer 200 is formed with four side walls of square grooves, i.e., the mounting groove 501, and the first magnetic field device 300 is also of plate-shaped structure and is just placed in the mounting groove 501, and four side edges of the first magnetic field device 300 are in contact with the four side walls of the mounting groove 501 to form a fixation.

It should be noted that, the first magnetic field device 300 and the assembly 500 may be fixed by interference, or may be fixed by an additional fixing structure (such as an adhesive, a screw, etc.).

In addition, when the fitting 500 is fixedly connected to the drawer 200, detachable connection may be used, or when the fitting is fixedly connected to the inner tub 110, detachable connection or non-detachable connection may be used.

The fixing position of the second magnetic field device 400 to the bottom wall of the drawer 200 may be fixed outside the bottom wall of the drawer 200, or may be fixed inside the bottom wall of the drawer 200, or may be an interlayer provided on the bottom wall of the drawer 200, and may be provided in the interlayer. The fixing mode can be an adhesive mode, a screw fixing mode, a mode of arranging a jogged groove on the outer surface or the inner surface of the bottom wall of the drawer 200, and the like. The first magnetic field device and the second magnetic field device are provided on the front-rear side or the left-right side with reference to the above-described mounting structure.

By providing the mounting groove 501 on the side of the fitting 500 facing the drawer 200, the first magnetic field means 300 can be clamped in the mounting groove 501 and thereby fixed to the bottom of the fitting 500. Such that there is no barrier between the first magnetic field device 300 and the inner space of the drawer 200, so that the magnetic field of the first magnetic field device 300 effectively acts in the inner space of the drawer 200. Moreover, the installation structure is simple, and the operation is convenient.

Referring to fig. 6 to 13, there is a space between the fitting plate (i.e., the fitting 500) and the first magnetic field device 300, the top surface of the fitting plate contacts the inner top wall of the inner tub 110, and the fitting plate is provided with ventilation holes 502 corresponding to the ventilation holes 111 to guide cool air flow from the ventilation holes 111 into the space between the fitting plate and the first magnetic field device 300 through the ventilation holes 502, thereby improving a cooling effect of the inner space of the drawer 200 and also neutralizing a magneto-caloric phenomenon during the operation of the first magnetic field device 300.

As shown in fig. 3 to 12, the side wall of the installation groove 501 is formed with three wind-running areas 503, and the wind-running areas 503 communicate with the accommodating compartment 101 and the space between the mounting plate and the first magnetic field device 300. Three wind passing areas 503 are provided at the left, rear and right sides of the assembly plate, respectively.

That is, the cool air flow entering the interval between the assembly plate and the first magnetic field device 300 flows along the surface of the first magnetic field device 300, and flows to the left, right and rear sides, can flow out of the wind passing region 503 to enter the accommodating compartment 101. Moreover, since the first magnetic field device 300 covers the top wall opening of the drawer 200, the cool air flowing out from the air-passing area 503 may spread downward along the left side wall, the right side wall and the rear side wall of the drawer 200, thereby uniformly cooling the drawer 200 and improving the uniformity of the temperature of the drawer 200.

It should be noted that in other embodiments, only the through hole may be provided on the top side wall of the inner tub body, and no surrounding air path may be provided, and at this time, the cold air flow in the first air flow path may directly flow from the front end to the outside of the whole fresh-keeping storage container.

It should be noted that, in other embodiments, only the surrounding air passage may be provided, and no through hole is provided on the top side wall of the inner tub. That is, the first air flow path indirectly guides the cool air flow into the accommodating compartment.
