Description

Fresh-keeping storage container and refrigerator

Technical Field

The utility model relates to the technical field of refrigeration and freezing, in particular to a fresh-keeping storage container and a refrigerator.

Background

Refrigerators are a common home appliance capable of storing foods using a low temperature, thereby extending the storage life of the foods. Along with the improvement of the living standard of people, the fresh-keeping effect of the refrigerator is also more and more important. It is found that the magnetic field can be used for assisting in storing food materials, and has a great improvement effect on the fresh-keeping effect of the food materials. One of the points is that under the action of the magnetic field, the food can be refrigerated under the subzero state, namely the food is not frozen under the subzero state, and the state that the food is not frozen under the subzero state is called supercooled non-freezing state.

While the supercooled non-frozen state of the food material is very sensitive to temperature, if the temperature is below the proper subzero range, it will freeze due to excessive supercooling. Therefore, it is necessary to ensure that the temperature of the food storage space is in a proper range so as to avoid overcooling of the food. Therefore, in early days, the applicant created the problem that the food material is locally excessively supercooled due to direct blowing of cold air by using the barrel body and the drawer to form the storage container and refrigerating the food material by arranging the air duct surrounding the inner space of the drawer.

In the applicant's early proposals, for the air duct at the top of the tub, one implementation was that the top wall of the tub included a shield plate and a top plate, the shield plate being located on the side of the top plate facing the drawer with a space between the shield plate and the top plate, thereby forming the part of the air duct located on the top side of the storage compartment, and the magnetic field members were mounted on the shield plate. Another implementation is that the top magnetic field member may act directly as a shield for the tub. In a first implementation, the top plate is the outer top wall of the tub, and the shielding plate is the inner top wall of the tub.

However, in this scheme, since the temperature of the cool air used for cooling the refrigerator is low, in the first implementation, the air duct is formed by the tub and the outer and inner top walls, resulting in direct contact of the cool air with a portion of the inner top wall of the tub, the cool air may be transferred into the inner space of the tub only through the heat conduction of the inner top wall of the tub, and the temperature of the inner space of the tub adjacent to the inner top wall of the tub, which is in direct contact with the cool air, may be significantly lower than that of other portions, where the partial overcooling occurs. In a second implementation manner, the air duct at the top of the barrel body and the inner space of the barrel body only separate the magnetic field component, and the cold energy can be transferred to the inner space of the barrel body only through the magnetic field component, so that the overcooling condition can occur in the corresponding area of the inner space of the barrel body.

In another aspect of the utility model, there is also provided a refrigerator comprising a fresh storage vessel according to any one of the above.

Optionally, the refrigerator comprises a box body, the box body defines a storage compartment, and the fresh-keeping storage container is arranged in the storage compartment.

According to the fresh-keeping storage container, the air supply and return air duct is defined between the magnetic field assembly and the air duct cover plate, and the magnetic field assembly enables the air supply and return air duct and the side wall of the inner barrel body to be mutually isolated in air flow communication, namely, cold air flowing in the air supply and return air duct cannot contact the side wall of the inner barrel body and can be conducted into the accommodating chamber only through double-layer isolation of the magnetic field assembly and the side wall of the inner barrel body, so that a proper amount of cold energy can be transferred into the accommodating chamber, the whole accommodating chamber can be kept at a proper storage temperature, and the problem of local overcooling in the accommodating chamber can be effectively avoided.

In addition, the magnetic field assembly becomes one of the duct walls of the duct. The magnetic field component can generate a magnetic field, so that the fresh-keeping effect of food materials is improved, and the magnetic field component can be used as an air duct wall to form an air duct, so that the structure of the fresh-keeping storage container is simplified. In addition, compared with the scheme that the magnetic field assembly is placed in the air duct and wrapped by the whole air duct, on one hand, the magnetic field assembly of the scheme forms the air duct wall, and the space occupied by the whole air duct and the magnetic field assembly is reduced. On the other hand, cold air can only pass through one side face of the magnetic field assembly, that is, the magnetic field assembly of the scheme can not form obstruction to cold air flowing, and smooth cold air flowing is guaranteed.

Furthermore, the fresh-keeping storage container forms the air passage depression on the air passage cover plate, so that the air passage cover plate can form three side walls of the air passage, and the magnetic field assembly forms the other side wall of the air passage. That is, the air duct is formed by the magnetic field assembly and the air duct cover plate, so that the cooling capacity in the air supply and return air duct can be further ensured to be transferred to the accommodating compartment only through the magnetic field assembly and the side wall of the inner barrel body. In addition, compared with two opposite side walls of the air duct formed by the air duct cover plate and the magnetic field assembly and the other two side walls of the air duct formed by other components, the air supply air duct is formed by only using the air duct cover plate and the magnetic field assembly, and the structure is further simplified. Moreover, only the air duct cover plate and the magnetic field assembly are required to be sealed, sealing is facilitated, and the sealing effect is better.

Furthermore, the fresh-keeping storage container of the utility model is provided with the even magnetic plate and the permanent magnetic sheet, and the even magnetic plate and the air channel cover plate limit the air channel. In the process that cold air flows through the air duct, the even magnetic plate can play the effect of even temperature, is favorable to holding indoor even cooling. However, since the shim plate has a relatively good heat conduction effect, if only the magnetic field assembly is used to separate the air duct from the accommodating chamber, the accommodating chamber is prone to a problem of local overcooling. However, because the heat conduction effect of the permanent magnet sheet is poor, and the side wall of the inner barrel body is separated, the even magnetic plate, the permanent magnet sheet and the side wall of the inner barrel body are mutually matched, the problem that excessive supercooling occurs in the accommodating chamber can be avoided under the condition of arranging the even magnetic plate, the temperature uniformity in the accommodating chamber can be improved, and unexpected effects are achieved.

Because the temperature of the cold air directly introduced from the space where the evaporator for cooling the refrigerating storage compartment is located is very low and is generally below-6 ℃ and at the lowest is even up to-10 ℃, the cold air can be conducted into the accommodating compartment only by making the cold air pass through double-layer isolation of the magnetic field assembly and the side wall of the inner barrel body, so that the cold air carried by the cold air can be conducted into the accommodating compartment in a heat isolation manner through the magnetic field assembly and the side wall part of the inner barrel body in the process of flowing in the air supply duct, namely, only part of the cold air can be conducted into the accommodating compartment through isolation of the magnetic field assembly and the side wall of the inner barrel body. Therefore, even if the temperature of cold air flowing out of the space where the evaporator is located is very low, the proper amount of cold air can be transferred to the accommodating chamber after at least double-layer heat conduction of the magnetic field assembly and the side wall of the inner barrel body, so that the temperature of the side wall of the inner barrel body facing the accommodating chamber is kept at more than or equal to-3 ℃, and the proper temperature for storing food materials below zero is maintained, and the food materials are kept in a non-freezing state below zero.

Further, the permanent magnet sheet is made of a composite material of ferrite magnetic powder and synthetic rubber, the thickness of the permanent magnet sheet is made to be more than 2 mm, an air heat insulation layer is arranged, and the thickness of the air heat insulation layer is set to be more than or equal to 1 mm and less than or equal to 3 mm. Under the structure, the low-temperature cold air from the space where the evaporator is located is matched, on one hand, the permanent magnet sheet meeting the materials and the thickness and the air heat insulation layer meeting the thickness are met, and the side wall of the inner barrel body is additionally provided with the expected proper heat conduction effect, so that the low-temperature cold air from the space where the evaporator is located is ensured to conduct proper cold energy to the accommodating chamber through the magnetic homogenizing plate, the permanent magnet sheet, the air heat insulation layer and the side wall of the inner barrel body, the temperature of the side wall of the inner barrel body facing to the accommodating chamber is truly maintained to be above-3 ℃, the temperature of the side wall of the inner barrel body is below zero ℃, the problem of overcooling of the accommodating chamber is avoided, and the fresh-keeping effect on food materials is ensured.

On the other hand, the permanent magnet sheet meeting the requirements of the materials and the thickness also reliably generates a magnetic field meeting the requirements in the accommodating room, so that the food materials in the accommodating room are ensured to be subjected to proper magnetic field action, that is, the required range of keeping the magnetic field and the temperature in the accommodating room is ensured, and the fresh-keeping effect of the food materials is ensured. Moreover, the fresh-keeping storage container with the structure can maintain the temperature of cold air flowing into the cold air transfer channel (namely directly entering the accommodating chamber) at a proper subzero temperature after heat exchange, and can still ensure the temperature of food to be maintained in a proper temperature range when the heat exchange is carried out to the food through the bottom wall of the drawer, thereby realizing the effect that the magnetic field and the temperature of the whole accommodating chamber are in the proper ranges.

As shown in fig. 1 to 7, in one embodiment, the fresh storage vessel includes a tub 100, a drawer 200, a magnetic field assembly 300, and a duct cover 400. The tub 100 includes an outer case 110 and an inner tub 120. The outer case 110 is sleeved outside the inner tub 120, and the inner tub 120 defines the accommodating compartment 101. A sandwich space 102 is formed between the top sidewall of the outer case 110 and the top sidewall of the inner tub 120. The magnetic field assembly 300 and the air duct cover 400 are disposed in the interlayer space 102, and the air duct cover 400 is disposed on a side of the magnetic field assembly 300 facing away from the accommodating compartment 101. The magnetic field assembly 300 generates a magnetic field that acts on the receiving compartment 101. The opposite sides of the air duct cover 400 and the magnetic field assembly 300 form an air supply and return duct isolated from each other in air flow communication with the sidewall of the inner tub 120, such that the air flowing through the air supply and return duct flows only through the air supply and return duct without contacting the sidewall of the inner tub 120. Specifically, the magnetic field assembly 300 and the duct cover 400 form a complete and continuous air supply and return duct, in other words, an air supply and return duct having an air inlet and an air outlet only at two ends of the extending direction of the magnetic field assembly 300 and the duct cover 400 is formed between them. In the extending direction of the whole air supply and return duct, the cold air entering the air supply and return duct can flow out of the air supply and return duct only through the whole air supply and return duct, and the cold air in the air supply and return duct can only contact with the magnetic field assembly 300 and cannot contact with the side wall of the inner barrel 120.

Referring to fig. 1 to 4, an air inlet 103 is provided at the rear end of the fresh storage container, and an air supply and return duct is an air supply duct 10 to guide the air flow from the air inlet 103 forward through the air supply duct 10. Further, the drawer 200 is drawably provided in the accommodating compartment 101. The drawer 200 defines a storage space 201. The front end plate 210 of the drawer 200 defines the ventilation duct 20. The cold air duct 30 is defined between the bottom of the drawer 200 and the inner surface of the bottom sidewall of the inner tub 120.

The supply air duct 10, the over-air duct 20, and the cool air duct 30 together constitute an air path surrounding the storage space 201. The fresh-keeping storage container is also provided with an air return port 104, cold air enters the air supply duct 10 from the air inlet 103, flows along the air supply duct 10 and enters the air passing duct 20, flows along the air passing duct 20 and enters the cold air transferring duct 30, and finally flows out of the container from the air return port 104.

It should be noted that, in other embodiments, the internal air path of the fresh-keeping container may also be formed by other surrounding manners, such as from left to front, from front of the drawer to right, and then from right back to back, that is, surrounding the fresh-keeping container in the transverse direction. Alternatively, the cold air does not pass through the drawer, for example, enters from the top of the inner barrel body, flows back and forth, flows to the left side or the right side, and flows back and forth to flow out of the whole air path structure. That is, the air supply and return air duct formed by the magnetic field assembly and the air duct cover plate can be arranged on the top side wall, the bottom side wall, the left side wall or the right side wall of the barrel body when being used as the air supply and return air duct.

It should be noted that in other embodiments, the fresh-keeping container may not have an outer casing, i.e. only the inner tub, and the magnetic field assembly and the air duct cover are located between the inner tub side wall and the refrigerator cabinet inner wall.

That is, the magnetic field assembly and the duct cover may be disposed outside any one of the sidewalls (top, bottom, rear, left, right) of the inner tub to form the supply and return air duct.

Referring to fig. 5, in particular, the inner tub 120 has a box shape as a whole and has a forward opening (i.e., an opening of the accommodating compartment 101). That is, the inner tub 120 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 the accommodating compartment 101 having an opening.

As shown in fig. 1 to 6, the drawer 200 is drawably disposed inside the inner tub 120 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 120 such that a closed storage environment is formed inside the inner tub 120, that is, such that the storage space 201 of the drawer 200 is closed in the accommodating compartment 101, whereby the drawer 200 and the inner tub 120 together define a fresh-keeping space. In a state that the drawer 200 is pulled out of the inner tub 120, the storage space 201 of the drawer 200 is exposed to the outside for taking and placing the stored objects.

Referring to fig. 3 and 8, the magnetic field assembly 300 includes a shim plate 310 and a source magnet 320. The air distribution plate 310 and the duct cover 400 define the air supply duct 10. The source magnet 320 is disposed on a side of the shim plate 310 facing away from the tunnel cover 400. The source magnet 320 is used to generate a magnetic field.

The shim plate 310 is made of a magnetically conductive material, such as silicon steel. The source magnetic unit 320 has a structure composed of a permanent magnet 321 and an electromagnetic coil 322. The permanent magnet sheet 321 may be made of a permanent magnet material having a certain flexibility, for example, a rubber magnet sheet having a flexibility made by compounding bonded ferrite magnetic powder with synthetic rubber and a calendaring process may be used. The thickness of the permanent magnet sheet 321 is greater than 2 mm, and may be, for example, 3 mm, 3.2 mm, 3.5 mm, etc. Preferably, the permanent magnet sheet 321 has a thickness of 3.2 mm. 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. That is, the shim plate 310, the permanent magnet pieces 321, and the electromagnetic coil 322 are arranged in a stacked manner from top to bottom.

The surface of the magnetic field assembly 300 opposite to the duct cover 400, that is, the surface of the shim plate 310 opposite to the duct cover 400, that is, the opposite side of the shim plate 310 to the duct cover 400 defines the supply air duct 10.

One of the requirements for a long-term fresh-keeping of the fresh-keeping storage container is to maintain the temperature in the compartment 101 within a suitable fresh-keeping temperature range, and the refrigeration process will not be too low or too high, especially to ensure that the temperature of each region of the compartment 101 is uniform. In some embodiments, the freshness temperature range may be set at greater than-3 degrees celsius and less than 0 degrees celsius. The stored articles are not only prevented from being frozen, but also can be kept at the preservation temperature below zero. The preservation temperature range can be set by a person skilled in the art according to the specific state of the stored object, and the specific numerical range is only illustrative.

Another requirement for a long-term fresh-keeping storage of fresh-keeping storage containers is the application of a magnetic field of suitable strength within the holding compartment 101. Through intensive research on the preservation effect, the magnetic field parameters of the preservation storage container in this embodiment are preferentially configured as the effective magnetic field intensity range: 10-100GS (1-10 mT), further can be set to 20-80GS, still further can be set to 40GS-60GS, e.g. 10GS, 20GS, 40GS, 60GS, 80GS, 100GS, etc., effective spacing range of magnetic fields: 60-240mm, effective spacing range of magnetic field: 60-240mm, i.e. the magnetic field may reach the above strength requirements in a distance range of 60mm to 240mm from the magnetic source component.

In the solution of this embodiment, the air supply and return air duct is defined between the magnetic field assembly 300 and the air duct cover 400, and the magnetic field assembly 300 makes the air supply and return air duct and the side wall of the inner tub 120 separate from each other in terms of air flow, that is, cold air flowing in the air supply and return air duct cannot contact the side wall of the inner tub 120, and must pass through the double-layer separation between the magnetic field assembly 300 and the side wall of the inner tub 120 to transfer cold energy into the accommodating compartment 101, so that an appropriate amount of cold energy can be provided to the accommodating compartment 101, which is helpful for keeping a suitable storage temperature in the entire accommodating compartment 101, and can effectively avoid the problem of local overcooling in the accommodating compartment 101.

As set forth in the background art, those skilled in the art consider that excessive supercooling of food materials can be well avoided as long as it is ensured that cold air does not blow directly over the food materials, but do not recognize the problem of excessive supercooling caused by cold air transfer to the food material storage space. On this basis, the person skilled in the art considers that only cold air does not directly blow food materials, and technical prejudices exist. This is seen in the prior art by using only the magnetic field means as the duct wall between the food storage space and the duct. Since the magnetic field member has the magnetic homogenizing plate, the heat conductivity of the magnetic homogenizing plate is good, so that the air duct and the food material storage space are separated only by the magnetic field member, the cooling effect is good, the problem of local overcooling is very easy to cause, and the overcooling problem caused by cooling is not recognized by a person skilled in the art.

In this technical solution, the applicant creatively recognizes that the excessive supercooling problem is also caused by the cold transfer of the cold wind to the food storage space (i.e. the accommodating compartment 101), so that the magnetic field assembly 300 isolates the air duct and the side wall of the inner tub 120 from each other, so that the cold wind must pass through the double-layer isolation of the magnetic field assembly 300 and the side wall of the inner tub 120 to transfer the cold energy into the accommodating compartment 101, thereby realizing more accurate temperature control, effectively avoiding the excessive supercooling problem, breaking through the prior thought confinement, and overcoming the prior technical prejudice.

In addition, the magnetic field assembly 300 becomes one of the duct walls of the duct. The magnetic field assembly 300 can generate a magnetic field, so that the fresh-keeping effect of food materials is improved, and an air duct can be formed as an air duct wall, so that the structure of the fresh-keeping storage container is simplified. Moreover, in one aspect, the magnetic field assembly 300 of the present embodiment forms a duct wall that helps reduce the space occupied by the entire duct plus magnetic field assembly as compared to a solution where the magnetic field assembly is disposed in the duct and wrapped by the entire duct. On the other hand, the cold air can only pass through one side surface of the magnetic field assembly 300, that is, the magnetic field assembly 300 of the present embodiment does not form a barrier to the cold air flow, which helps to ensure the smooth cold air flow.

In addition, the magnetic field assembly 300 includes a shim plate 310 and permanent magnet pieces 321, and the shim plate 310 and the air duct cover 400 define an air duct. In the process of cold air flowing through the air duct, the magnetic homogenizing plate 310 can play a role in homogenizing temperature, and is beneficial to uniformly cooling in the accommodating compartment 101. Moreover, as described above, since the heat conduction effect of the shim plate 310 is relatively good, if only the magnetic field assembly 300 is used to separate the air duct from the accommodating compartment 101, it is very easy to cause excessive supercooling in the accommodating compartment 101. However, because the heat conducting effect of the permanent magnet sheet 321 is poor, and the side wall of the inner tub 120 is also separated, the even magnet plate 310 and the permanent magnet sheet 321 are mutually matched with the side wall of the inner tub 120, so that the problem of overcooling of the accommodating compartment 101 can be avoided under the condition of arranging the even magnet plate 310, and the temperature uniformity in the accommodating compartment 101 can be improved, thereby achieving unexpected effects.

Further, the permanent magnet sheet 321 is made of a composite material of ferrite magnetic powder and synthetic rubber, and the thickness of the permanent magnet sheet 321 is made to be larger than 2 mm, so that on the basis that the permanent magnet sheet 321 has enough source magnetism to generate a magnetic field meeting requirements in the accommodating chamber 101, the permanent magnet sheet 321 has a proper heat conduction effect, proper cold quantity is ensured to be conducted to the accommodating chamber 101 by cold air through the even magnetic plate 310, the permanent magnet sheet 321 and the side wall of the inner barrel 120, the problem that overcooling occurs in the accommodating chamber 101 is avoided, the required range of the magnetic field and the temperature in the accommodating chamber 101 is maintained, and the fresh-keeping effect on food materials is ensured.

It should be noted that, in other embodiments, the source magnetic member may be a permanent magnet sheet alone, or an electromagnetic coil alone.

Referring to fig. 3, preferably, the drawer 200 in the closed position causes the projection of the storage space 201 to fall within the shim plate 310 on a plane where a face of the shim plate 310 faces the drawer 200. That is, in a state where the drawer 200 is in the closed position, the magnetic homogenizing plate 310 covers the entire storage space 201, thereby securing a magnetic homogenizing effect on the entire storage space 201.

It should be noted that, in other embodiments, the magnetic field assembly is disposed outside the left side wall or the right side wall of the inner tub to form the air supply and return duct, and the same configuration may be adopted.

Further, as shown in fig. 1, the air inlet 103 is provided at a rear portion of the top sidewall of the tub 100 near a rear sidewall of the tub 100. The air return port 104 is disposed at one lateral side of the air inlet 103 and spaced from the air inlet 103.

In some embodiments, the air return opening is communicated with the space of the refrigerator storage compartment outside the fresh-keeping storage container, the air flow of the fresh-keeping storage container after heat exchange is returned to the refrigerator storage compartment through the air return opening, and the air flow circulation is completed by using the air return passage of the refrigerator storage compartment to the evaporator cavity of the refrigerator.

In other embodiments, the refrigerator can also be provided with a fresh-keeping container return air channel communicated with the return air inlet, and the fresh-keeping container is directly sent back to the evaporator cavity of the refrigerator through the air flow after heat exchange.

As shown in fig. 9 to 12, the air duct cover 400 is configured to form an air duct recess 401 on a side facing the magnetic field assembly 300, and the air duct recess 401 extends from a rear end of the air duct cover 400 to a front end of the air duct recess 401 to define the air supply duct 10 with the magnetic field assembly 300.

Specifically, the duct cover 400 has a certain thickness facing the inward wind path recess 401 of the magnetic field assembly 300 and penetrating through the front and rear ends of the duct cover 400. When the duct cover 400 is assembled with the magnetic field assembly 300 in place, the portions of the duct cover 400 on either side of the air path recess 401 contact the magnetic field assembly 300 to form a seal. Also, since the air path recess 401 penetrates opposite ends of the air path cover 400, the air path recess 401 and the magnetic field assembly form the supply air duct 10 extending from the rear end to the front end of the air path cover 400.

By forming the wind path recess 401 in the wind path cover 400, the wind path cover 400 can form three sidewalls of the wind path, and the magnetic field assembly 300 forms the other sidewall of the wind path. That is, the air duct is completely formed by the magnetic field assembly 300 and the air duct cover 400, so that it is further ensured that the cooling capacity in the air supply and return air duct can be transferred to the accommodating compartment 101 only through the magnetic field assembly 300 and the side wall of the inner tub 120, and the problem of local overcooling of the accommodating compartment 101 is effectively avoided. In addition, the structure is further simplified by forming the supply air duct 10 with only two components of the duct cover 400 and the magnetic field assembly 300, as compared to two opposite side walls of the duct formed by the duct cover 400 and the magnetic field assembly 300 and the other two side walls of the duct formed by other components. Moreover, only the air duct cover plate 400 and the magnetic field assembly 300 need to be sealed, so that the sealing is convenient, and the sealing effect is better.

The sealing between the magnetic field assembly and the air duct cover plate can be direct contact sealing between the magnetic field assembly and the air duct cover plate, or indirect contact sealing through two sealing strips arranged between the magnetic field assembly and the air duct cover plate, wherein the two sealing strips are arranged on two sides of the air supply air duct.

With continued reference to fig. 9-12, the air path recess 401 in the air duct cover 400 expands from the air inlet end to the air outlet end. Thereby facilitating the diffusion of cold air in the air supply duct 10 and improving the cooling uniformity.

Further, both opposite side walls of the wind path recess 401 are at least partially in a smooth curve shape, and the portion in the smooth curve shape is connected with the wind inlet end. That is, the left and right side walls of the supply air duct 10 have smooth curved portions, thereby facilitating improvement of smoothness of the flow of the cool air. Preferably, the smooth curve protrudes outside the wind path recess 401, i.e., left side to the left side and right side to the right side.

It should be noted that two opposite side walls of the air path recess may be both linear.

As shown in fig. 9 to 12, three flow dividing ribs 410 are provided in the air supply duct 10, and the flow dividing ribs 410 extend in the front-rear direction of the air supply duct 10 to divide the air supply duct 10 into a plurality of air passages distributed in the left-right direction.

Specifically, three flow dividing ribs 410 are distributed in the left-right direction of the air supply duct 10, dividing the air supply duct 10 into four air passages. Specifically, the duct cover 400 is made of a heat insulating material, such as a foam material. Meanwhile, the shunt rib 410 is formed by protruding a side of the air duct cover 400 facing the magnetic field assembly 300 toward the magnetic field assembly 300. That is, the diverting rib 410 is integrally formed with the duct cover 400.

By arranging the flow dividing ribs 410 in the air supply duct 10, air flow entering the air supply duct 10 is dispersed to the left and right sides, so that the air flow is distributed more uniformly in the air supply duct 10, and the temperature uniformity of the air supply duct 10 is further improved by matching with the temperature uniformity effect of the magnetic homogenizing plate 310. And, the diverting rib 410 and the air duct cover plate 400 are integrally formed, so that the air duct cover plate 400 is well supported, and the structural strength of the air duct cover plate 400 is improved.

It should be noted that in other embodiments, the number of the flow dividing ribs may be one, two, four or more.

Referring to fig. 9 to 12, specifically, along the direction of the two sides of the position of the flow dividing rib 410 closest to the central axis of the air inlet 103, the distance between the end of the flow dividing rib 410 closest to the air inlet 103 and the plane of the air inlet 103 is greater. Specifically, among the three flow dividing ribs 410, the middle flow dividing rib 410 is closest to the central axis of the air intake 103 (broken line in fig. 12). The plane where the air inlet 103 is located is taken as a reference plane, and the distance between the end parts of the middle flow dividing ribs 410 and the reference plane is smaller than the distance between the end parts of the two flow dividing ribs 410 on two sides and the reference plane. Through the above construction, the flow dividing rib 410 is caused to generate a step-by-step flow dividing effect, so that the flow dividing effect is better.

It should be noted that the number of the flow dividing ribs on two sides of the flow dividing rib closest to the central axis of the air inlet may be different. In addition, when the number of the flow dividing ribs is even, the two flow dividing ribs can be the central axis closest to the air inlet, and only one flow dividing rib can be the central axis closest to the air inlet.

Referring to fig. 9 to 12, further, the inlet width of the air path is increased along the direction of both sides of the position corresponding to the central axis of the air inlet 103. Specifically, the three flow-splitting ribs 410 separate four air path paths. For the left two air path, the inlet width of the air path near the left is larger than the inlet width of the air path near the middle. For the two right-side air path, the inlet width of the air path closer to the right is larger than the inlet width of the air path closer to the middle.

That is, the inlet width of the air path is made larger the farther from the air inlet 103, so that a larger air intake is obtained, and thus the air distribution is made more uniform.

As further shown in fig. 1, 11 to 14, the rear end of the top side wall of the outer case 110 has an inclined section 111, and the air intake 103 is formed in the inclined section 111. The tilting direction of the tilting section 111 is directed from top to bottom in the front-to-rear direction. The rear end of the duct cover 400 is formed with an inclined surface 420 that mates with the inclined section 111, a structural interface 402 is formed at the inclined surface 420, and the inclined surface 420 is fitted to the inner surface of the inclined section 111 so that the structural interface 402 is aligned with the air intake 103 to allow air flow from the air intake 103 into the supply air duct 10.

Specifically, in a state in which the duct cover 400 is assembled with the outer case 110 in place, the duct cover 400 is fitted to the inner surface of the top wall of the outer case 110, including the fit between the inclined surface 420 of the duct cover 400 and the inner surface of the inclined section 111. That is, in a state where the duct cover 400 is assembled with the outer case 110 in place, the inclined direction of the inclined surface 420 of the duct cover 400 is identical to the inclined direction of the inclined section 111. The interface 402 is configured to align with the air inlet 103 such that cool air from outside the fresh container can enter the supply air duct 10 through the air inlet 103.

By providing the inclined section 111 in the outer case 110, the air intake 103 is formed in the inclined section 111, thereby facilitating air supply to the air supply duct 10. But also the section of the outer housing 110 provided with the air inlet 103 is brought into a longitudinally fitting relationship with the duct cover 400, facilitating compression of the outer housing 110 and the duct cover 400.

Referring to fig. 11 to 14, the outer case 110 is formed with a longitudinal extension 112 at the front end of the inclined section 111, the duct cover 400 is formed with a longitudinal extension 430 engaged with the longitudinal extension 112, and the duct cover 400 and the outer case 110 are assembled in place such that the longitudinal extension 430 is fitted with the inner surface of the longitudinal extension 112.

Specifically, the longitudinally extending section 112 is located at the front end of the inclined section 111 and meets the inclined section 111. In the assembled state of the duct cover 400 and the outer housing 110, the duct cover 400 is in engagement with the inner surface of the top wall of the outer housing 110, including engagement between the longitudinally extending surface 430 of the duct cover 400 and the inner surface of the longitudinally extending section 112. The longitudinally extending surface 430 cooperates with the longitudinally extending segment 112 to locate the assembly of the duct cover 400 with the outer housing 110.

Referring to fig. 11 to 14, further, a positioning groove 403 is provided at one side of the duct cover 400, and a positioning rib 113 is provided at the inner side of the top wall of the outer case 110. The positioning groove 403 cooperates with the positioning rib 113 to perform a positioning function for assembling the duct cover 400 and the outer case 110.

As shown in fig. 3 and 15, the front end of the air duct 10 is further provided with an air supply hole 105. The top end of the air passage 20 is provided with an air receiving hole 202. When the drawer 200 is in the closed position, the air flow entering from the air inlet 103 is guided to the air passing channel 20 through the air supply channel 10, and sequentially enters the air passing channel 20 through the air supply hole 105 and the air receiving hole 202.

As shown in connection with fig. 15 and 16, the fresh food storage receptacle further includes an end plate fitting 130, wherein the end plate fitting 130 is provided at the front end of the tub 100, surrounds the opening of the accommodating compartment 101, and is assembled with the outer case 110 and the inner tub 120, thereby closing the supply air duct 10. Meanwhile, the air supply hole 105 is formed in the end plate fitting 130, so that the air flow in the air supply duct 10 can flow out of the air supply hole 105.

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-keeping storage container includes only the inner tub, the air supply hole may be formed by an air duct cover plate.

Referring to fig. 3, 4 and 6, in particular, the front end plate 210 of the drawer 200 includes a panel 211 and an end plate fan housing 212. An end plate fan housing 212 is provided inside the panel 211, the end plate fan housing 212 defining the ventilation duct 20. The end plate wind cover 212 protrudes from the panel 211 toward the storage space 201, and the left side wall, the right side wall, and the bottom side wall of the end plate wind cover 212 are all located inside the storage space 201. The air receiving holes 202 are formed in the top side wall of the end plate duct 212.

The air duct may be defined by the end plate cover and the panel together, or may be formed by the end plate cover alone (i.e., the end plate cover has a side wall that is bonded to the inner side 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. 3 and 15, the plane in which the outlet of the air supply hole 105 is located is inclined toward the top of the fresh food storage vessel in a direction away from the rear end of the fresh food storage vessel. The plane in which the inlet of the air-receiving hole 202 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 105 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 120. The plane in which the outlet of the air-sending hole 105 is located is the plane in which the bottom side face of the portion is located, that is, the plane in which the side face facing away from the air-sending duct 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 202 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 air passing duct 20.

As shown in fig. 3 and 15, the plane of the air supply hole 105 and the plane of the air receiving hole 202 are inclined in the same direction, i.e., both the direction from front to back to the bottom of the fresh food storage container.

By tilting the plane of the outlet of the air supply hole 105 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 of the inlet of the air receiving hole 202 is tilted toward the bottom of the drawer 200 in a direction away from the panel 211. In the process that the cold air enters the air passing duct 20 from the air supply duct 10, the flowing route of the cold air is in a parabolic shape as a whole, so that the cold air flows between the air supply hole 105 and the air receiving hole 202 more smoothly, and the air leakage is reduced. In addition, the inclined surface at the top of the end plate fan housing 212 is also beneficial to reducing the probability of foreign matters falling into the over-air duct 20.

Referring to fig. 15 and 17, the included angle between the plane of the outlet of the air blowing hole 105 and the vertical direction is 10 degrees or more and 80 degrees or less. The included angle between the plane where the inlet of the air receiving hole 202 is located and the vertical direction is greater than or equal to 10 degrees and less than or equal to 80 degrees.

Referring to fig. 15 and 17, the angle a, which is the angle between the plane in which the outlet of the air blowing hole 105 is located and the vertical direction, is the designed value of the angle a, and the designed value range is 10 degrees or more and 80 degrees or less. For example, it may be 10 degrees, 20 degrees, 26 degrees, 30 degrees, 33 degrees, 40 degrees, 45 degrees, 50 degrees, 54 degrees, 60 degrees, 68 degrees, 70 degrees, 73 degrees, 80 degrees. Preferably, the included angle between the plane of the outlet of the air supply hole 105 and the vertical direction is greater than or equal to 60 degrees and less than or equal to 75 degrees. For example, 60 degrees, 62 degrees, 64 degrees, 70 degrees, 72 degrees, 75 degrees may be used.

Referring to fig. 15 and 17, the angle b, which is the angle between the plane in which the inlet of the air receiving hole 202 is located and the vertical direction, is that is, the design value of the angle b ranges from 10 degrees or more to 80 degrees or less. For example, it may be 10 degrees, 20 degrees, 26 degrees, 30 degrees, 33 degrees, 40 degrees, 45 degrees, 50 degrees, 54 degrees, 60 degrees, 68 degrees, 70 degrees, 73 degrees, 80 degrees. Preferably, the included angle between the plane where the inlet of the wind receiving hole 202 is located and the vertical direction is greater than or equal to 60 degrees and less than or equal to 75 degrees. For example, 60 degrees, 62 degrees, 64 degrees, 70 degrees, 72 degrees, 75 degrees may be used.

In addition, in the present embodiment, the plane in which the inlet of the air receiving hole 202 is located is parallel to the plane in which the inlet of the air receiving hole 202 is located, that is, the angle between the plane in which the outlet of the air supplying hole 105 is located and the vertical direction is equal to the angle between the plane in which the inlet of the air receiving hole 202 is located and the vertical direction. For example, the angle between the plane of the outlet of the air hole 105 and the vertical direction is 70 degrees, and the angle between the plane of the inlet of the air hole 202 and the vertical direction is 70 degrees.

The included angle between the plane where the outlet of the air supply hole 105 is located and the vertical direction is greater than or equal to 10 degrees and less than or equal to 80 degrees, and the included angle between the plane where the inlet of the air receiving hole 202 is located and the vertical direction is greater than or equal to 10 degrees and less than or equal to 80 degrees, so that the end plate fan housing 212 and the barrel body 100 are convenient to produce on the basis of ensuring smooth airflow.

As shown in fig. 15 and 17, the distance from any point in the outlet region of the air blowing hole 105 to the plane on which the inlet of the air receiving hole 202 is located is 3 mm or more and 20 mm or less. That is, any point in the outlet of the air blowing hole 105 is perpendicular to the plane in which the inlet of the air receiving hole 202 is located, and the length of the perpendicular (the distance d in fig. 15) is 3 mm or more and 20 mm or less. For example, it may be 3 mm, 5 mm, 8 mm, 10 mm, 15 mm, 20 mm, etc. Preferably, the distance is 10 mm or more and 20 mm or less. For example, it may be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, etc.

By making the distance from any point in the outlet area of the air supply hole 105 to the plane where the inlet of the air receiving hole 202 is located 3 mm or more and 20 mm or less, on the one hand, the air leakage is prevented from being serious due to the excessively large distance between the air supply hole 105 and the air receiving hole 202. On the other hand, the friction between the end plate fan housing 212 and the barrel body 100 caused by the fact that the air sending holes 105 and the air receiving holes 202 are too close to each other in the moving process of the drawer 200 is avoided.

Referring to fig. 15, the area of the inlet of the air receiving hole 202 is equal to or larger than the area of the outlet of the air sending hole 105. The projection of the outlet region of the air blowing hole 105 onto the plane on which the inlet of the air receiving hole 202 is located falls within the inlet region of the air receiving hole 202. Preferably, the ratio of the area of the inlet of the air receiving hole 202 to the area of the outlet of the air blowing hole 105 is 2 or less. With the above configuration, it is advantageous to ensure that the cool air flows into the over-air duct 20 as much as possible.

As shown in fig. 6 and 15, a plurality of partition ribs 2121 are provided in the wind receiving hole 202, and the partition ribs 2121 extend in the left-right direction of the drawer 200. Specifically, both ends of each of the partition ribs 2121 are respectively connected to the left and right hole walls of the air receiving hole 202, and the plurality of partition ribs 2121 are distributed along the front-rear direction of the drawer 200, thereby partitioning the air receiving hole 202 into a plurality of regions. Preferably, the spacing between two adjacent separation ribs 2121 is 1 mm or more and 3 mm or less. For example, it may be 1 mm, 2 mm, 3 mm, etc.

By providing a plurality of separation ribs 2121 in the wind receiving hole 202, the wind receiving hole 202 is divided into a plurality of areas, which is beneficial to reducing the condition that the airflow generates vortex in the wind receiving hole 202. By controlling the spacing between the separation ribs 2121, it is advantageous to prevent foreign matter from falling into the over-air duct 20.

Further, as shown in fig. 15, the tips of the partitioning ribs 2121 are formed with smooth curved surfaces protruding toward the tip of the end plate fan housing 212. Thereby helping to make the cool air more smoothly enter the wind passing duct 20.

The wind receiving hole 202 may or may not have a rib perpendicular to or intersecting with the partition rib 2121.

Referring to fig. 15 and 16, a single reinforcing rib 140 and a plurality of reinforcing ribs 150 are provided in the air supply hole 105, the reinforcing rib 140 extending in the left-right direction of the tub 100, and the reinforcing ribs 150 extending in the front-rear direction of the tub 100. The reinforcing rib 150 is connected to the reinforcing rib 140.

Wherein the reinforcing ribs 150 are in the form of a sheet. Extending in the front-rear direction of the tub 100 in the lateral direction. In the longitudinal direction, a part of the air flow path is located in the air supply hole 105, and a part of the air flow path extends into the air supply duct 10 and extends out of the air supply hole 105. That is, the reinforcing rib 140 and one reinforcing rib 150 form a cross-shaped structure for dividing the air flow to prevent the generation of vortex in the air supply hole 105.

Further, as shown in fig. 15, the fresh storage vessel also includes a seal 500. The sealing member 500 is disposed inside the top wall of the inner tub 120. The drawer 200 in the closed position causes the sealing member 500 to seal the gap between the front end plate 210 of the drawer 200 and the front end of the inner tub 120, to prevent the leakage of cool air from the air supply hole 105 to the air receiving hole 202 while the cool air is flowing into the drawer 200.

Specifically, when the drawer 200 is in the closed position, the inner side of the panel 211 and the front end of the end plate fitting 130 are abutted, thereby functioning to close the accommodating chamber 101. The seal 500 and the end plate wind cap 212 abut against and function to reduce the flow of the cool wind toward the storage space 201. In other words, the panel 211, the end plate mating member 130 and the sealing member 500 together define a relatively closed passageway between the small section of the air supply hole 105 and the air receiving hole 202, so that cold air can flow into the air passing duct 20 as much as possible, thereby reducing air leakage into the storage space 201 and avoiding the problem of local overcooling of the accommodating compartment 101.

As shown in conjunction with fig. 18 and 19, in particular, the seal 500 includes a support portion 510 and a seal portion 520. The support part 510 is used to be connected with the inner tub 120. The sealing portion 520 has one end connected to the support portion 510 and the other end adapted to abut against the end plate fan housing 212. The support part 510 is made of a relatively hard material (e.g., PP (polypropylene) material) so as to be firmly coupled with the inner tub 120. The seal 520 is made of a softer material (e.g., TPE (Thermo Plastic Elastomer, thermoplastic elastomer) material, rubber, etc.) to facilitate deformation in contact with the endplate bellows 212 to achieve a better seal.

Referring to fig. 18 to 20, the support portion 510 is formed with a coupling groove 501, and the inner tub 120 is provided with a coupling rib 160. The fitting rib 160 is inserted into the fitting groove 501 to connect the sealing member 500 with the inner tub 120. Specifically, the cross section of the support portion 510 is generally "U" shaped, and the mating groove 501 is a "U" shaped recess.

By adopting the assembly mode of matching the matching groove 501 and the matching rib 160, the assembly process of the sealing element 500 and the inner barrel body 120 is more convenient, and the sealing element 500 can be detachably connected with the inner barrel body 120, so that the sealing element 500 is convenient to replace.

It should be noted that, in other embodiments, the sealing member may be assembled on the tub by an adhesive, a screw fixing, or the like.

It should be noted that in other embodiments, the seal may be provided on the front end panel of the drawer.

As shown in fig. 3 and 18 to 20, one end of the seal portion 520 is in contact with the notch end of one side wall of the fitting groove 501, and the other end extends in the opening direction of the fitting groove 501. Accordingly, correspondingly, the fitting rib 160 provided on the inner tub 120 is formed to extend forward and backward. In other words, the coupling groove 501 of the support part 510 is caught on the coupling rib 160 in the rear-to-front direction of the inner tub 120. Alternatively, after the sealing member 500 is assembled with the inner tub 120 in place, the opening of the fitting groove 501 is oriented to coincide with the opening of the accommodating compartment 101.

Because in the contact process of the end plate fan housing 212 and the sealing member 500, the sealing portion 520 receives the pressure of the end plate fan housing 212 pointing to the rear of the inner barrel 120, and one end of the sealing portion 520 is connected with the notch end of one side wall of the matching groove 501, and the other end extends towards the opening direction of the matching groove 501, so that when the sealing portion 520 receives the pressure, the pressure can be transferred to the supporting portion 510, and then the matching groove 501 can offset part of the pressure in a slight expansion deformation mode, thereby reducing the pressure burden received at the joint of the sealing portion 520 and the supporting portion 510, and being beneficial to improving the service life of the sealing member 500.

In other embodiments, one end of the sealing portion may be connected to the outside of the groove bottom wall of the mating groove, and the other end may extend in a direction away from the opening of the mating groove. In addition, the assembly direction of the matching groove and the matching rib can be along the top-bottom direction of the barrel body.

As shown in fig. 19 and 20, the first rib 511 is provided on the inner side of the side wall of the fitting groove 501 which is in contact with the seal 520. The engaging rib 160 is provided with a catching rib 161 engaged with the first protruding rib 511. The seal 500 and the mating rib 160 are assembled in place such that the catch 161 is located on the side of the first ridge 511 remote from the notch of the mating groove 501. The first ribs 511 and the catching ribs 161 are provided with guide surfaces that cooperate with each other.

Specifically, the catching rib 161 is formed by the bottom side of the fitting rib 160 protruding downward, and the first protruding rib 511 is formed by the side wall of the fitting groove 501 that meets the sealing part 520 protruding toward the side wall of the other fitting groove 501. During the assembly of the seal 500 and the fitting rib 160, the side of the first rib 511 where the guide surface is provided contacts the side of the clamping rib 161 where the guide surface is provided, specifically, the side of the first rib 511 near the notch of the fitting groove 501 contacts the clamping rib 161. As the sealing member 500 continues to be assembled with the engaging rib 160, that is, as the engaging rib 160 is continuously inserted into the engaging groove 501, the first convex rib 511 passes over the catching rib 161 under the guide of the guide surface and then returns under the elastic action of itself. Then, the catching rib 161 is located at a side of the first protruding rib 511 away from the notch of the fitting groove 501, and the catching rib 161 overlaps with the first protruding rib 511 in the front-rear direction of the tub 100.

By providing the first rib 511 in the engagement groove 501, the engagement rib 160 is provided with the engagement rib 161 engaged with the first rib 511. After the seal 500 and the fitting rib 160 are assembled in place, the catching rib 161 is located at a side of the first protruding rib 511 away from the notch of the fitting groove 501, so that the catching rib 161 and the first protruding rib 511 cooperate with each other to function to prevent the seal 500 from being separated from the fitting rib 160.

As shown in fig. 19 and 20, the inner side of the side wall of the fitting groove 501, which is in contact with the sealing portion 520, is provided with a second bead 512, and the second bead 512 is located on the side of the first bead 511, which is away from the notch of the fitting groove 501. The seal 500 and the mating bead 160 are assembled in place such that the catch bead 161 is located between the first bead 511 and the second bead 512 and such that the tip of the second bead 512 abuts the mating bead 160.

Similarly, the second bead 512 is formed by protruding the inner side of the side wall of the fitting groove 501 that meets the seal 520 toward the side wall of the other fitting groove 501. The top of the second rib 512 is curved to reduce interference with the mating rib 160 during assembly of the seal 500.

Through setting up second protruding muscle 512 at the cooperation groove 501, the sealing member 500 and the cooperation muscle 160 of assembly target in place make the top butt of second protruding muscle 512 cooperate muscle 160 to can play the reinforcement effect to the assembly of sealing member 500 and cooperation muscle 160, improve structural stability.

Wherein, the height of the protrusions of the first convex rib 511 and the second convex rib 512 is the same, which is less than or equal to one fourth of the width (the distance between the two groove side walls) of the mating groove 501.

As shown in fig. 19 and 20, the inner side of the sidewall of the fitting groove 501 opposite to the first rib 511 is provided with a third rib 513. The third protruding rib 513 and the fitting rib 160 are provided with mutually fitting guide surfaces, and the seal 500 and the fitting rib 160 fitted in place are such that the tip of the third protruding rib 513 abuts the fitting rib 160.

Specifically, the third beads 513 are formed by protruding from the inner side of the sidewall of the fitting groove 501 opposite to the first beads 511 toward the sidewall where the first beads 511 are located, and the third beads 513 are formed at the notched ends of the sidewall. A guide surface is formed at a side of the third rib 513 near the notch. In addition, a guide surface on the fitting rib 160 is formed on the top side of the protruding end of the fitting rib 160. The third beads 513 can act as guides during the assembly of the sealing member 500 and the fitting bead 160. After the seal 500 and the fitting rib 160 are assembled in place, the tip of the third protruding rib 513, that is, abutting the fitting rib 160, can function to reinforce the assembly of the seal 500 and the fitting rib 160.

As shown in fig. 18 and 19, further, the sealing portion 520 is a flexible fin, the sealing portion 520 is curved, and a side of the sealing portion 520 near the supporting portion 510 is a curved convex side. Specifically, with reference to the end of the sealing portion 520 that is in contact with the support portion 510, the entirety of the curved sealing portion 520 is located on the side of the contacting side wall that is away from the mating groove 501. The other end of the sealing portion 520 is spaced apart from the end of the sealing portion 520 in contact with the supporting portion 510 in both the lateral and longitudinal directions. And the two ends are bent. The side of the sealing part 520 near the supporting part 510 is a curved convex side, in other words, a concave side of the curved sealing part 520 is seen from the view of the mating groove 501 from the front of the notch of the mating groove 501.

By providing the sealing portion 520 as a curved flexible fin, the side of the sealing portion 520 near the support portion 510 is a curved convex side. During the contact of the sealing portion 520 with the end plate fan housing 212, the end of the sealing portion 520 remote from the support portion 510 is brought into contact with the end plate fan housing 212. As the drawer 200 continues to close, the sealing portion 520 is pressurized by the end panel housing 212, because of the special configuration of the sealing portion 520, the sealing portion 520 has two points that are easily deformed, one being the junction of the sealing portion 520 and the support portion 510, and the other being the middle of the sealing portion 520. On the one hand, the sealing part 520 is easier to deform so as to buffer the pressure applied to the sealing part 520, thereby prolonging the service life of the sealing part 520. On the other hand, the sealing portion 520 can maintain the bending direction of the base in the process of being extruded, but the bending degree is increased, so that the guiding direction of the sealing portion 520 to the cold air is maintained towards the side where the air receiving hole 202 is located, and the smooth flow of the air flow is facilitated.

In other embodiments, the sealing portion may be an elastic block.

Further, as shown in fig. 19, the curvature of the sealing portion 520 decreases in the extending direction from one end of the sealing portion 520 in contact with the supporting portion 510 to the other end. That is, the degree of bending of the sealing portion 520 becomes gradually gentle from one end of the sealing portion 520, which is in contact with the supporting portion 510, toward the other end. It is advantageous to ensure that the end of the sealing portion 520 remote from the support portion 510 is in contact with the end plate fan housing 212.

Further, as shown in fig. 19, in the extending direction from one end of the sealing portion 520 to the other end of the supporting portion 510, the thickness of the middle section of the sealing portion 520 is larger than the thickness of both ends. Thus, both ends of the sealing part 520 are more easily deformed, feedback resistance of the sealing member 500 is reduced, and user experience is improved.

Preferably, the thickness variation from the end of the seal 520 to the middle section varies from 0.2 mm to 1 mm, i.e., the end thickness is 0.2 mm and the middle section thickness is 1 mm.

Further, the ratio of the longitudinal distance from the end of the sealing portion 520 away from the supporting portion 510 to the thickest portion of the sealing portion 520 to the longitudinal distance from the end of the sealing portion 520 connected to the supporting portion 510 to the other end (i.e., the distance H in the drawing) is one-third or more and one-half or less. For example, it may be one third, two fifths, one half, etc.

The ratio of the lateral distance from the end of the sealing portion 520 where the supporting portion 510 is in contact with to the thickest portion of the sealing portion 520 to the lateral distance from the end of the sealing portion 520 where the supporting portion 510 is in contact with (i.e., the distance S in the drawing) is one-seventh or more and one-third or less. For example, it may be one seventh, one sixth, one fourth, one third, etc.

Through the above-mentioned structure, be favorable to making the one end that sealing part 520 kept away from supporting part 510 produce upward deformation more easily under the extrusion of drawer 200 for sealing part 520 is receiving the in-process of extrusion, can keep the crooked direction of basis, and just crooked degree can increase, then makes sealing part 520 keep the direction of leading to cold wind to be the side that is located towards the air receiving hole 202, the smooth and easy flow of air current of being convenient for.

Further, as shown in fig. 19, a notch 502 is provided at the junction of the sealing portion 520 and the supporting portion 510, and the notch 502 is located at the side of the sealing portion 520 facing the bottom of the mating groove 501. Specifically, the cross-sectional shape of the notch 502 is arcuate. By providing a notch at the junction of the sealing portion 520 and the supporting portion 510, the junction of the sealing portion 520 and the supporting portion 510 is more easily deformed.

The design value of the minimum thickness of the notch 502 is more than or equal to 0.2 mm and less than or equal to 0.4 mm. And is one-fourth to one-half, including one-fourth and one-half, of the maximum thickness of the sealing portion 520.

As shown in fig. 19, the longitudinal distance from one end of the sealing portion 520, which is in contact with the supporting portion 510, to the other end is 5 mm or more and 15 mm or less. The lateral distance from one end of the sealing portion 520 to the other end of the supporting portion 510 is 5 mm or more and 20 mm or less. As shown in the drawing, the longitudinal distance H from one end of the sealing portion 520 to the other end of the supporting portion 510, that is, H is 5 mm or more and 15 mm or less, and may be, for example, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, or the like. Preferably, the longitudinal distance from one end of the sealing part 520 to the other end of the supporting part 510 is 8 mm or more and 12 mm or less.

Referring to fig. 19, the lateral distance S from one end of the sealing portion 520 to the other end of the supporting portion 510, that is, S is 5 mm or more and 20 mm or less, and may be, for example, 5 mm, 6 mm, 10 mm, 13 mm, 15 mm, 20 mm, or the like. Preferably, the lateral distance from one end of the sealing portion 520 to the other end of the supporting portion 510 is 10 mm or more and 15 mm or less.

If the extension length of the sealing part 520 is too small, the deformation effect is bad, affecting the sealing effect. And the extension length of the sealing part 520 is too large, which also causes waste.

Referring to fig. 15, when the drawer 200 is in the closed position, the end of the sealing portion 520 that is in contact with the support portion 510 is spaced from the top wall of the end plate fan housing 212 by a distance of 5 mm or more and 10 mm or less. For example, it may be 5 mm, 7 mm, 8 mm, 10 mm. The end of the sealing part 520 connected with the supporting part 510 is ensured to have a certain longitudinal distance from the top end of the end plate fan housing 212, so that the deformation resistance can be reduced, and the sealing effect can be ensured.

As shown in fig. 15, the end plate fan housing 212 is provided with a boss 2122 on a side facing the inside of the drawer 200. The boss 2122 extends in the left-right direction of the drawer 200, and the top surface position of the boss 2122 in the closed position of the drawer 200 is lower than or flush with the lowest end position of the seal 500 in the natural state. Specifically, the top surface of boss 2122 and the side of end plate housing 212 facing the inside of drawer 200 form an angular surface. When the sealing part 520 is bent, a part of the sealing part contacts with the surface of the end plate fan housing 212 and a part contacts with the top surface of the boss 2122, thereby forming a cavity together with the angular surface, which is beneficial to improving the sealing effect.

As shown in fig. 3, 21 and 22, the bottom side wall of the end plate fan housing 212 is provided with four air outlet holes 203. Corresponding through holes are also formed in the bottom side wall of the drawer 200, so that air flow in the air passing duct 20 flows out of the air outlet 203 and flows into the air passing duct 30 through the through holes in the bottom side wall of the drawer 200.

Wherein, an air outlet sets up the left end at end plate fan housing 212 bottom side wall, and an air outlet sets up the right-hand member at end plate fan housing 212 bottom side wall, and an air outlet sets up the middle part at end plate fan housing 212 bottom side wall, and an air outlet sets up between the air outlet of end plate fan housing 212 one end of keeping away from the air intake and the air outlet in the middle.

Specifically, the end plate fan housing 212 is located at an end far from the central axis of the air inlet 103 in a transverse direction perpendicular to the central axis of the air inlet 103. That is, the end of the end plate fan housing 212 far from the air inlet 103 has a larger air outlet area relative to the end close to the air inlet 103, so that the bottom air outlet of the end plate fan housing 212 is more uniform.

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. 4, 5 and 7, specifically, the rear sidewall of the inner tub 120 is formed at a position near the top end with the air outlet 106, and the longitudinally extending air outlet duct 40 is formed between the rear sidewall of the inner tub 120 and the rear sidewall of the outer case 110, and the top end of the air outlet duct 40 communicates with the air return 104. The cool air flows from the cool air transfer duct 30 to the rear end of the drawer 200, then flows upwards to the air passing hole 106, flows into the air passing duct 40 from the air passing hole 106, then flows to the air return opening 104 along the air passing duct 40, 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 air supply duct 10 from the air inlet 103, and then flows through the air supply duct 10 from the rear to the front. At the front end of the supply duct 10, air flows through the supply hole 105 and the air receiving hole 202 into the top end of the wind passing duct 20 defined in the front end plate 210 of the drawer 200, and then flows through the wind passing duct 20 from top to bottom. At the bottom end of the air passing duct 20, air flows into the air passing duct 30 between the bottom plate of the drawer 200 and the bottom wall of the inner tub 120, and then flows through the air passing duct 30 from front to back. At the connection position of the rear end of the bottom plate of the drawer 200 and the rear plate of the drawer 200 (i.e., the rear end of the cooling air duct 30), air flow enters the gap between the rear plate of the drawer 200 and the rear wall of the inner tub 120. And then flows from the air outlet 106 into the air outlet duct 40, and the air flow finally reaches the air return opening 104 along the air outlet duct 40.

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.

In addition, the internal air path of the fresh-keeping storage container also fully considers the problem of cold transfer effect. Specifically, the air supply duct 10 is formed by the magnetic field assembly 300 and the duct cover 400, that is, cold air outside the fresh container first enters between the magnetic field assembly 300 and the duct cover 400. Therefore, the temperature of the air flow in the air duct 10 is the lowest. However, since cold air must be transferred to the accommodating compartment through the double-layered heat insulation structure composed of the magnetic field assembly 300 and the inner tub 120, that is, the transfer of cold air is most difficult, it is possible to effectively prevent the occurrence of local overcooling in the accommodating compartment 101 in combination. Then, the cold air exchanges heat step by step in the flowing process, and the temperature of the cold air rises gradually. In the air passage 20, the cooling difficulty of the drawer end plate is easier than that of the air passage 10, but the air temperature is higher, so that the local overcooling in the accommodating compartment 101 can be effectively avoided. The gap between the drawer bottom plate and the bottom wall of the barrel body is used as the cold air transfer channel 30, the cold energy exchanges heat with the drawer bottom plate, the cold energy is most easily transferred, but the air temperature is also highest, so that the combination of the two components can effectively avoid local overcooling in the accommodating compartment 101. That is, as the temperature of the air flow increases, the heat exchange difficulty of each air path section is relatively easier, so that the temperature of each position of the fresh-keeping storage space is generally equivalent, and the problem of local overcooling is well avoided.

As shown in fig. 3, 4 and 8, further, the fresh storage vessel is provided with two sets of magnetic field assemblies 300. Two sets of magnetic field assemblies 300 are disposed outside the top sidewall and outside the bottom sidewall of the inner tub 120, respectively. The fresh-keeping storage container further comprises two magnetic conductive pieces 600. The two magnetic conductive members 600 are disposed outside the left and right sidewalls of the inner tub 120, respectively. The two ends of the magnetic conductive member 600 are respectively connected with the shim plates 310 in the two magnetic field assemblies 300, so that the two magnetic field assemblies 300 and the two magnetic conductive members 600 form an annular magnetic field loop together, the magnetic field utilization rate is improved, and the influence of the magnetic field on external components is reduced.

It should be noted that, in other embodiments, when the magnetic field assemblies are disposed outside the left side wall or the right side wall of the inner tub to form the air duct, the two magnetic field assemblies may be disposed on the left side wall and the right side wall of the tub, and the two magnetic conductive members may be disposed on the top side wall and the bottom side wall, respectively.

Referring to fig. 7 and 23, further, in the magnetic field assembly 300 forming the supply air duct 10, a heat insulating layer 50 is formed between the magnetic field assembly 300 and the top wall of the inner tub 120. The thermal insulation layer 50 is an air thermal insulation layer. Specifically, the top wall of the inner tub 120 is provided with a raised support rib 121. After the inner tub 120 is assembled in place, the bottom surface of the permanent magnet piece 321 abuts against the top end of the support rib 121. Then, the permanent magnet pieces 321 are supported by the supporting ribs 121, so that an air gap is formed between the permanent magnet pieces 321 and the top wall of the inner tub 120, thereby forming an air heat insulation layer.

On the one hand, the supporting ribs 121 can play a role in supporting and pressing the permanent magnet pieces 321, so that the permanent magnet pieces 321 are more firmly installed, the permanent magnet pieces 321 are prevented from shifting in the using process, the permanent magnet pieces 321 and the magnetic homogenizing plate 310 are more tightly matched, and the magnetic homogenizing effect of the magnetic homogenizing plate 310 is improved. On the other hand, the supporting ribs 121 support the permanent magnet pieces 321 to form an air heat insulation layer between the permanent magnet pieces 321 and the top wall of the inner barrel body 120, so that cold energy of cold air is conducted into the accommodating chamber 101 through the magnetic field assembly 300, the air heat insulation layer and the side wall of the inner barrel body 120, the air heat insulation layer plays a transitional role between the magnetic field assembly 300 and the side wall of the inner barrel body 120, the process that the cold energy is conducted from the magnetic field assembly 300 to the side wall of the inner barrel body 120 is more gentle, the proper cold energy can be provided for the accommodating chamber 101 more effectively, and the problem that local overcooling occurs in the accommodating chamber 101 is more effectively avoided.

Preferably, the thickness of the air insulating layer is set to 1 mm or more and 3 mm or less, and may be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or the like, for example. By the arrangement, the air heat insulation layer keeps proper heat conduction effect, the temperature of the accommodating chamber 101 is kept at a reasonable temperature, the temperature is not too high or too low, and the air heat insulation layer is prevented from occupying a large space.

It should be noted that, in other embodiments, the thermal insulation layer may also be a thermal insulation board (such as a thermal insulation foam board, a thermal insulation plastic board, etc.). In addition, under the condition that the magnetic field assembly and the air duct cover plate form an air supply and return air duct on the other side wall of the inner barrel body, a heat insulation layer can be arranged.

It should be noted that, in other embodiments, the magnetic field assembly may also be directly attached to the side wall of the inner tub.

Although not shown in the drawings, in one embodiment, the rear side of the tub is provided with a return air inlet, and the return air inlet is a return air inlet, so that the air flow entering the fresh-keeping storage container is directly or indirectly guided to the return air inlet through the return air inlet.

It should be noted that, when the air supply and return duct formed by the magnetic field assembly and the duct cover plate is used as the air return duct, the air supply and return duct can be arranged on the top side wall, the bottom side wall, the left side wall or the right side wall of the barrel body.

As shown in fig. 24, in one embodiment, the bottom side wall, the left side wall, and the right side wall of the end plate fan housing 212 are each provided with an air outlet 203. Therefore, the air flow in the over-air duct 20 can flow out from the bottom side wall, the left side wall and the right side wall of the end plate fan housing 212, so that the cold air is in full contact with the wall of the drawer 200, and the temperature in the storage space 201 (refer to fig. 6) in the drawer 200 is reduced more uniformly.

The number of the air-sending holes on the left side wall, the right side wall and the bottom side wall is at least one.

Referring to fig. 24, further, a first air guiding rib 220 and a second air guiding rib 230 are provided in the air duct 20, one end of the first air guiding rib 220 is connected to the inner surface of the left side wall of the end plate fan housing 212 and is lower than the bottommost end of the air outlet 203 provided in the left side wall of the end plate fan housing 212, and the other end extends to the top end of the air duct 20. One end of the second wind guide rib 230 is connected with the inner surface of the right side wall of the end plate fan housing 212 and is lower than the bottommost end of the wind outlet 203 arranged on the right side wall of the end plate fan housing 212, and the other end extends to the top end of the wind passing channel 20. And, a space is provided between the first wind guide rib 220 and the second wind guide rib 230.

Specifically, at the top end position of the wind-passing wind channel 20, that is, the wind-receiving position, one end of the first wind-guiding rib 220 and the second wind-guiding rib 230 near the top end of the wind-passing wind channel 20 divides the wind-receiving area of the wind-passing wind channel 20 into three parts, that is, a part between the end of the first wind-guiding rib 220 and the left side wall of the end plate wind housing 212, a part between the end of the first wind-guiding rib 220 and the end of the second wind-guiding rib 230, and a part between the second wind-guiding rib 230 and the right side wall of the end plate wind housing 212.

Therefore, the cool air entering the air duct 20 is divided into three air flows under the guidance of the first air guiding rib 220 and the second air guiding rib 230, and one part flows to the air outlet 203 of the left side wall of the end plate air cover 212, one part flows to the air outlet 203 of the right side wall of the end plate air cover 212, and one part flows to the bottom side of the end plate air cover 212. Therefore, by providing the first air guide rib 220 and the second air guide rib 230, cold air can flow to the left side wall, the right side wall and the bottom side wall of the end plate fan housing 212 as evenly as possible, so that the cooling of the storage space 201 is more uniform.

When the left side wall or the right side wall is provided with the plurality of air outlet holes 203, one end of the first air guiding rib 220 connected to the inner surface of the left side wall of the end plate fan housing 212 is lower than the lowest end of the air outlet holes 203 provided on the left side wall of the end plate fan housing 212, that is, lower than the lowest end of all the air outlet holes 203. The same is true of the second wind-guiding rib 230.

Further, as shown in fig. 24, the ratio of the distance between the end of the first wind-guiding rib 220 near the top of the wind channel 20 and the leftmost end of the wind receiving hole 202 (see fig. 6) to the distance between the leftmost end and the rightmost end of the wind receiving hole 202 is greater than or equal to one fourth and less than or equal to one third. For example, the ratio is one quarter, two-seventh, one third, etc.

And, the ratio of the distance between the end of the second wind-guiding rib 230 near the top of the wind channel 20 and the rightmost end of the wind receiving hole 202 to the distance between the leftmost end and the rightmost end of the wind receiving hole 202 is more than or equal to one fourth and less than or equal to one third. For example, the ratio is one quarter, two-seventh, one third, etc.

Although the wind receiving hole 202 is not shown, the above ratio relationship may be illustrated. As shown in the figure, D is the distance from the leftmost end to the rightmost end of the wind receiving hole 202, D1 is the distance from the leftmost end of the wind receiving hole 202 to the end of the first wind guiding rib 220 near the top of the wind passing wind channel 20, and D2 is the distance from the rightmost end of the wind receiving hole 202 to the end of the second wind guiding rib 230 near the top of the wind passing wind channel 20. That is, D1/D is one-fourth or more and one-third or less. D2/D is more than or equal to one fourth and less than or equal to one third.

The ratio of the distance between the end of the first wind guide rib 220 near the top of the wind channel 20 and the leftmost end of the wind receiving hole 202 to the distance between the leftmost end of the wind receiving hole 202 and the rightmost end of the wind receiving hole 202 is greater than or equal to one fourth and less than or equal to one third, and the ratio of the distance between the end of the second wind guide rib 230 near the top of the wind channel 20 and the rightmost end of the wind receiving hole 202 to the left and right distances of the wind receiving hole 202 is greater than or equal to one fourth and less than or equal to one third, so that the uniformity of the cold wind flowing to the left side wall, the right side wall and the bottom side wall of the end plate fan housing 212 is ensured.

With continued reference to fig. 24, further, the lowest end of the air outlet 203 on the left side wall of the end plate air cover 212 is higher than or flush with one half of the height of the storage space 201. And, the lowest end position of the air outlet 203 of the right side wall of the end plate fan housing 212 is higher than or flush with one half of the height of the storage space 201.

By making the lowest end position of the air outlet 203 on the left side wall of the end plate fan housing 212 higher than or flush with one half of the height of the storage space 201, the lowest end position of the air outlet 203 on the right side wall of the end plate fan housing 212 is made higher than or flush with one half of the height of the storage space 201, when cold air flows out from the air outlets 203 on the left and right side walls of the end plate fan housing 212, the cold air flows to the rear end of the drawer 200 and simultaneously subsides downwards, which is beneficial to keeping the cold air in contact with the left and right side walls of the drawer 200 as much as possible, thereby ensuring heat exchange efficiency and cooling uniformity.

As shown in fig. 24, further, a third air guiding rib 240 and a fourth air guiding rib 250 are provided in the air duct 20. The top end of the third wind-guiding rib 240 is higher than the bottom end of the first wind-guiding rib 220, the bottom end of the third wind-guiding rib 240 is lower than the bottom end of the first wind-guiding rib 220, and the top end of the third wind-guiding rib 240 is closer to the middle of the wind-passing duct 20 than the bottom end. The top end of the fourth wind-guiding rib 250 is higher than the bottom end of the second wind-guiding rib 230, the bottom end of the fourth wind-guiding rib 250 is lower than the bottom end of the second wind-guiding rib 230, and the top end of the fourth wind-guiding rib 250 is closer to the middle of the wind-passing duct 20 than the bottom end. The third wind-guiding rib 240 is closer to the left side wall of the end plate wind housing 212 than the fourth wind-guiding rib 250, and a space is provided between the third wind-guiding rib 240 and the fourth wind-guiding rib 250.

Specifically, the third and fourth wind-guiding ribs 240 and 250 are located at the bottom sides of the first and second wind-guiding ribs 220 and 230, the third and fourth wind-guiding ribs 240 and 250 are distributed in the left-right direction, and the third wind-guiding rib 240 is closer to the left side. The third air guide rib 240 is inclined from left to right along the bottom of the air duct 20 to the top, and the fourth air guide rib 250 is inclined from right to left along the bottom of the air duct 20 to the top. It can also be said that the third air guide rib 240 and the fourth air guide rib 250 are symmetrical with respect to the longitudinal central axis of the wind passing duct 20.

The third air guide rib 240 and the fourth air guide rib 250 have a space therebetween, that is, the third air guide rib 240 and the fourth air guide rib 250 divide the cool air flowing in from between the first air guide rib 220 and the second air guide rib 230 into three strands again, that is, one strand at the left side of the third air guide rib 240, one strand between the third air guide rib 240 and the fourth air guide rib 250, and one strand at the right side of the fourth air guide rib 250.

Because the bottom plate of drawer is generally wider, so through setting up third wind-guiding muscle 240 and fourth wind-guiding muscle 250, can shunt once more to the air current of end plate fan housing 212 bottom lateral wall, help making cold wind distribute more evenly in the bottom of drawer to improve the heat transfer effect of cold wind and drawer bottom, improve the homogeneity of cooling.

As shown in fig. 24, further, a fifth air guiding rib 260 is disposed in the air duct 20, the fifth air guiding rib 260 is located between the third air guiding rib 240 and the fourth air guiding rib 250, the top end of the fifth air guiding rib 260 is lower than the top ends of the third air guiding rib 240 and the fourth air guiding rib 250, and the top end of the fifth air guiding rib 260 is higher than the bottom ends of the third air guiding rib 240 and the fourth air guiding rib 250. The fifth wind guide rib 260 is formed with a bend with a tip end facing the top end of the wind passing duct 20.

Specifically, the fifth wind guiding rib 260 is a triangle rib, and is an isosceles triangle rib, and the two isosceles corners are directed to the top end of the wind passing duct 20, so that when the cold wind flowing to the bottom side wall of the end plate fan housing 212 encounters the two isosceles corners of the triangle, the cold wind is directed to the two isosceles corners of the triangle.

The fifth air guide ribs 260 are beneficial to further dispersing cold air, so that the uniformity of cold air distribution at the bottom of the drawer is improved, and the uniformity of cooling is improved. In addition, due to the triangular design, the cold air is prevented from flowing back to the inside of the bending to form turbulent flow.

It should be noted that the fifth wind-guiding rib may be a triangle other than an isosceles triangle. In addition, the fifth wind guide rib can also be formed by bending a strip rib at one time. In addition, the bent tip of the fifth wind guide rib may be a smooth curved surface.

In this embodiment, other structures may be described with reference to the above embodiments.

When the end plate fan housing alone forms the air passage, the air guide ribs are formed on the end plate fan housing. When the end plate fan cover and the panel jointly form the over-air duct, the air guide ribs can be formed on the end plate fan cover or the panel.

As shown in fig. 25 to 27, in one embodiment, the air duct 10 is not provided with a diversion rib, and the air duct 20 is provided with an air guide member 270. Specifically, the air guiding member 270 is a triangular block with rounded corners in cross section, and one corner of the air guiding member 270 faces the top of the air passing duct 20, so that the air guiding member 270 can guide the air flow entering the air passing duct 20 to the left and right sides, and the cold air is distributed more uniformly at the bottom of the drawer.

Further, the air guiding member 270 may be made of a material with good heat conducting effect, such as pure metal materials like copper and aluminum, or other alloy materials. Because the air guide member 270 is a block, the heat exchange effect with the cold air in the air duct 20 can be improved when the air guide member is made of a material with a good heat conducting effect.

In other embodiments, as shown in fig. 28, the air guide members 270 are bar-shaped ribs. Two air guide members 270 are arranged in the air passing duct 20, the two air guide members 270 are distributed left and right, and each air guide member 270 is inclined towards the other air guide member 270 along the direction from the bottom to the top of the air passing duct 20. And there is a space between the two air guiding members 270. The two air guide members 270 are arranged in a relatively inclined manner, so that the air guide members can also disperse cold air.

In other embodiments, as shown in fig. 29, the air guide members 270 are bar-shaped ribs. Four air guiding members 270 are provided in the air duct 20. The four air guiding members 270 may be considered as two sets of two members. For each group, each wind guiding member 270 is inclined toward the other wind guiding member 270 in a direction from the bottom to the top of the wind passing duct 20, and a space is provided between the two wind guiding members 270.

At the same time, one set of components is located on the underside of the other set of components.

In other embodiments, as shown in fig. 30, the air guide members 270 are bar-shaped ribs. And the wind guide member 270 is bent to form a closed figure, and in particular, the wind guide member 270 is bent to form a diamond shape. One corner of the diamond is directed toward the top of the over-wind tunnel 20.

The air guide member may be formed into other polygons such as a triangle or a square.

As shown in fig. 31 and 32, in one embodiment, the refrigerator includes a case 1 and the fresh storage container 2 of any of the above embodiments. 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 side-by-side refrigerators shown in fig. 31 and 32 are only examples, and those skilled in the art can configure the number, functions and layout of the specific storage compartments according to the need.

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. 32 shows an example of a fresh food storage receptacle 2 disposed within a refrigerated storage compartment 11. Other storage drawers can be arranged in the refrigerating storage compartment 11 besides the fresh-keeping storage container 2, for example, fig. 32 shows an example of three other drawer-type storage containers in which one drawer-type storage container is transversely arranged in parallel with the fresh-keeping storage container 2, in addition to the fresh-keeping storage container 2.

As shown in fig. 1 to 23 and 31 to 33, the air inlet 103 of the fresh-keeping storage container 2 is used for communicating with a space where an evaporator for cooling the fresh-keeping storage compartment 11 is located, so that air flow is introduced from the space where the evaporator is located, and cold of the air flow is conducted to the accommodating compartment 101 through the magnetic field assembly 300 and the sidewall portion of the inner tub 120 in a thermally isolated manner, so that the temperature of the side of the sidewall of the inner tub 120 facing the accommodating compartment 101 is maintained to be greater than or equal to-3 ℃.

Specifically, fig. 33 is a schematic view of an air path of a refrigerator supplying cool air to the fresh-keeping storage container 2 according to an embodiment of the present utility model. A refrigerating air duct assembly 12 is arranged at the back of the refrigerating storage compartment 11. In fig. 33, for the purpose of illustrating the refrigerating duct assembly 12, other components of the refrigerating compartment 11 except for the fresh storage container 2 and the refrigerating duct assembly 12, such as a refrigerating liner, a compartment insulation layer, etc., are omitted. A refrigerating air supply fan 13 is arranged in the refrigerating air duct assembly 12, and a fresh-keeping container air supply air passage 14 is formed in the refrigerating air duct assembly 12, and an air inlet 103 of the fresh-keeping container 2 is communicated with a space where an evaporator for cooling the refrigerating storage compartment 11 is located through the fresh-keeping container air supply air passage 14. The refrigerating and air-supplying fan 13 promotes the formation of cold air flow which is blown from the space where the evaporator is located to the air inlet 103 of the fresh-keeping container 2 through the fresh-keeping container air-supplying air path 14.

The fresh container supply air path 14 is one of a plurality of supply air paths provided in the refrigeration duct assembly 12, and the on-off and/or the size of the air flow can be controlled and regulated. For example, an independent adjustable air door can be arranged in the fresh container air supply air path 14; for another example, the refrigeration stack assembly 12 may be provided with other types of airflow distribution devices that provide for controlled adjustment of the airflow to the fresh container supply air duct 14.

The refrigerating duct assembly 12 shown in fig. 33 may use a centrifugal fan as the refrigerating air supply fan 13, and the refrigerating air supply fan 13 sucks in the low-temperature air in the space where the evaporator is located from the rear, and forms a cold air flow that directly blows from the space where the evaporator is located to the air inlet 103 of the fresh container 2 through the fresh container air supply duct 14. Cold air enters the air supply duct 10 of the fresh-keeping storage container 2 through the air inlet 103.

Because the temperature of cold air directly introduced from the space where the evaporator is positioned is very low, the temperature is generally below-6 ℃, the minimum temperature can reach-10 ℃, and the temperature is far lower than the proper temperature for freezing food materials below zero. Therefore, the cold air must be conducted into the accommodating compartment 101 through the double-layer isolation of the magnetic field assembly 300 and the side wall of the inner tub 120, so that the cold air carried by the cold air is conducted into the accommodating compartment 101 through the magnetic field assembly 300 and the side wall portion of the inner tub 120 in a thermally isolated manner in the process of flowing the cold air in the air supply duct 10, that is, only a portion of the cold air can be conducted into the accommodating compartment 101 through the isolation of the magnetic field assembly 300 and the side wall of the inner tub 120. In this way, even if the temperature of the cold air flowing out of the space where the evaporator is located is very low, the cold air can be guaranteed to transfer a proper amount of cold energy to the accommodating compartment 101 after at least the double-layer heat conduction of the magnetic field assembly 300 and the side wall of the inner barrel 120, so that the temperature of the side wall of the inner barrel 120 facing the accommodating compartment 101 is maintained at a temperature of more than or equal to-3 ℃, and the proper temperature for storing the food materials below zero is maintained, so that the food materials are guaranteed to be in a non-freezing state below zero.

Further, the permanent magnet sheet 321 is made of a composite material of ferrite magnetic powder and synthetic rubber, and the thickness of the permanent magnet sheet 321 is made to be more than 2 mm, and an air heat insulation layer is provided, and the thickness of the air heat insulation layer is set to be more than or equal to 1 mm and less than or equal to 3 mm. Under the above structure, the low-temperature cold air from the space where the evaporator is located is matched, on one hand, the permanent magnet sheet 321 meeting the above materials and thickness, the air heat insulation layer meeting the above thickness and the side wall of the inner barrel body 120 are combined, so that the expected proper heat conduction effect is realized, the low-temperature cold air from the space where the evaporator is located is ensured to conduct proper cold energy to the accommodating chamber 101 through the magnetic homogenizing plate 310, the permanent magnet sheet 321, the air heat insulation layer and the side wall of the inner barrel body 120, the temperature of the side wall of the inner barrel body 120 facing the accommodating chamber 101 is truly maintained to be more than-3 ℃, the temperature of the side wall of the inner barrel body 120 is lower than zero ℃, the problem of excessive supercooling of the accommodating chamber 101 is avoided, and the fresh-keeping effect on food materials is ensured.

On the other hand, the permanent magnet 321 meeting the above-mentioned materials and thickness also reliably generates a satisfactory magnetic field in the accommodating compartment 101, ensuring that the food in the accommodating compartment 101 is subjected to a suitable magnetic field, that is, the required range for keeping the magnetic field and temperature in the accommodating compartment 101 is ensured, and the preservation effect of the food is ensured. In addition, the fresh-keeping storage container with the structure can maintain the temperature of the cold air flowing into the cold air duct 30 (i.e. directly entering the accommodating compartment 101) at a proper subzero temperature after heat exchange, and can still ensure the temperature of the food to be maintained in a proper temperature range when the heat exchange is performed to the food through the bottom wall of the drawer 200.

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.

The refrigerator of the embodiment is beneficial to the production of the refrigerator by configuring the magnetic field on the fresh-keeping storage container which is arranged in the compartment of the refrigerator. Of course, the refrigerator is enabled to realize magnetic field auxiliary storage of food materials.

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.
