Generally, the refrigerator 1 may include a cabinet 10, a door 20, a refrigeration system, and the like.

Referring to fig. 2 to 4, fig. 2 isbase:Sub>A schematic sectional view taken alongbase:Sub>A sectional linebase:Sub>A-base:Sub>A of fig. 1, fig. 3 isbase:Sub>A schematic sectional view taken alongbase:Sub>A sectional line B-B of fig. 1, and fig. 4 isbase:Sub>A rear view ofbase:Sub>A cabinet 10 ofbase:Sub>A refrigerator 1 according to an embodiment of the present invention, with an outer case hidden.

The cabinet 10 may include an outer case located at the outermost side of the whole refrigerator 1 to protect the whole refrigerator 1, and a plurality of inner containers. The inner containers are wrapped by the shell, and heat-insulating materials (forming foaming layers) are filled in spaces between the inner containers and the shell so as to reduce outward heat dissipation of the inner containers. Each inner container may define a storage space opened forward, and the storage spaces may be configured as a refrigerating chamber, a freezing chamber, a temperature changing chamber, etc., and the number and functions of the specific storage spaces may be configured according to a predetermined requirement.

Referring to fig. 1 and 4, in some embodiments, the refrigerator 1 may include a refrigerating inner container 110, a freezing inner container 120, and a temperature-changing inner container 130. The freezing liner 120 and the variable temperature liner 130 are both located on a first lateral side, the variable temperature liner 130 is disposed above the freezing liner 120, and the refrigerating liner 110 is disposed on a second lateral side, that is, the three liners are arranged in a side T shape.

Referring to fig. 1, the number of the door bodies 20 may also be the same as the number of the inner containers, that is, each storage compartment with the forwardly opened inner container may be opened and closed by the corresponding door body 20. The door 20 is movably disposed in front of the cabinet 10, for example, the door 20 may be hingedly disposed at one side of the front of the cabinet 10 to pivotally open and close the storage space.

The refrigeration system may include a compressor 32, a condenser (not shown), a throttle (not shown), and an evaporator 34. A compressor compartment 140 is disposed below the rear side of the box 10, both the compressor 32 and the condenser may be disposed in the compressor compartment 140, and the compressor 32 may compress a refrigerant into refrigerant vapor of high temperature and high pressure and deliver the refrigerant vapor to the condenser. The high-temperature and high-pressure refrigerant fully dissipates heat in the condenser to form high-pressure and normal-temperature refrigerant liquid. The throttling device depressurizes the high-pressure normal-temperature refrigerant liquid at the cold gas outlet to obtain a low-temperature low-pressure refrigerant, and the low-temperature low-pressure refrigerant is conveyed to the evaporator 34. The evaporator 34 evaporates (boils) the low-temperature and low-pressure refrigerant liquid therein into vapor, absorbs the heat of the cooled material, lowers the temperature of the material, and realizes the supply of cold energy into the storage compartment.

Referring to fig. 2, in some embodiments, one evaporator 34 may be provided, i.e., a single system refrigeration system, and the freezing liner 120 may define a freezing compartment 122 at a front side and a cooling compartment 123 at a rear side of the freezing compartment 122, and the evaporator 34 may be provided in the freezing compartment to provide cooling energy to the freezing compartment 122, the temperature-changing compartment 132, and the freezing compartment 122.

Specifically, the air path circulation system of the freezing compartment 122 is: a freezing air duct 124 is disposed in front of the rear wall of the freezing inner container 120 to divide the freezing inner container 120 into a freezing compartment 122 and a cooling compartment 123 for disposing the evaporator 34, and a freezing air outlet duct 124a is further defined inside the freezing air duct 124, a freezing air inlet 124b communicated with the cooling compartment 123 is disposed on the rear side of the freezing air outlet duct 124a, and a freezing air outlet 124c communicated with the freezing compartment 122 is disposed on the front side of the freezing air outlet duct 124 a. The bottom of the refrigerated air duct 124 also forms a refrigerated return air duct 126 that communicates between the refrigerated compartment 122 and the cooling compartment 123. The freezing air inlet 124b may be provided with an air supply fan 80, and under the driving of the air supply fan 80, the refrigerating air flow in the cooling chamber 123 enters the freezing air outlet duct 124a from the freezing air inlet 124b, and then is discharged into the freezing compartment 122 through the freezing air outlet 124c, so as to exchange heat with the food material and the air in the freezing compartment 122. After the heat exchange is completed, the air enters the cooling chamber 123 again from the bottom freezing return air duct 126, and exchanges heat with the evaporator 34 again, thereby forming a circulation.

Referring to fig. 2, 4 to 6, fig. 5 is a schematic view of a view angle of the duct forming member 40 in the refrigerator 1 according to an embodiment of the present invention, and fig. 6 is a schematic view of another view angle of the duct forming member 40 in the refrigerator 1 according to an embodiment of the present invention. The air path circulation system for the variable temperature compartment 132: an air duct forming member 40 is disposed in front of the rear wall of the temperature-changing liner 130 to divide the temperature-changing liner 130 into a temperature-changing chamber 132 which is open forward. A first air duct 410 is formed in the air duct forming member 40, and the air duct forming member 40 has a temperature varying air outlet 412 for communicating the first air duct 410 with the temperature varying chamber 132, and a temperature varying air inlet 414 for communicating the first air duct 410 with the freezing air outlet duct 124 a. Since the variable temperature compartment 132 is disposed above the freezing compartment 122, in order to facilitate the communication between the first air duct 410 and the freezing air outlet duct 124a, the variable temperature air inlet 414 may be disposed at the bottom of the air duct forming member 40 (the bottom wall of the variable temperature liner 130 also needs to be provided with an air inlet corresponding to the variable temperature air outlet 412). The variable temperature air inlet 414 and the freezing air outlet duct 124a can be connected by a first connecting member 50. During refrigeration, under the driving of the air supply fan 80, the refrigeration air flow in the freezing air outlet duct 124a is discharged into the first air duct 410 through the first connecting member 50 and the variable temperature air inlet 414, and then discharged into the variable temperature chamber 132 through the variable temperature air outlet 412 to exchange heat with the food material and the air in the freezing chamber 122. After the heat exchange is completed, the air in the temperature-varying chamber 132 may flow back into the cooling chamber 123 through the separately disposed temperature-varying return duct 134, and exchange heat with the evaporator 34 again to form a cycle.

With reference to fig. 2 to 4, the air path circulation system of the refrigerating compartment 114: a refrigerating air duct 112 is disposed in front of the rear wall of the refrigerating inner container 110 to divide the refrigerating inner container 110 into a refrigerating compartment 114 and a refrigerating air duct 116, a refrigerating air inlet 118 is disposed at a rear side portion of the refrigerating inner container 110 near the temperature-variable inner container 130, and a refrigerating air outlet 119 communicating the refrigerating air duct 116 with the refrigerating compartment 114 is disposed in the refrigerating air duct 112. A second air duct 420 independent from the first air duct 410 can be further formed in the air duct forming member 40 disposed in the temperature changing liner 130, the freezing air outlet duct 124a and the middle air inlet 422 of the second air duct 420 are communicated by the first connecting member 50, and the middle air outlet 424 and the cold storage air inlet 118 of the second air duct 420 are communicated by the second connecting member 52. During refrigeration, under the driving of the air supply fan 80, the refrigeration air flow in the freezing air outlet duct 124a sequentially enters the second air duct 420 through the first connecting piece 50 and the middle air inlet 422, then sequentially enters the refrigeration air duct 116 through the middle air outlet 424, the second connecting piece 52 and the refrigeration air inlet 118, and finally is discharged into the refrigeration compartment 114 through the refrigeration air outlet 119 to exchange heat with the food materials and the air in the refrigeration compartment 114. After the heat exchange is completed, the air in the refrigerating compartment 114 can flow back to the cooling compartment 123 through the separately arranged refrigerating return air duct 115, and exchanges heat with the evaporator 34 again to form a cycle.

Generally, because the density of the cold air is large, when air is supplied to each compartment, the air outlet is generally arranged at a higher position, so that the cold air can be fully diffused in the compartment along with the sedimentation of the cold air, and the temperature field distribution of the compartment is uniform.

In the side T-shaped refrigerator 1 of the present embodiment, the temperature-changing liner 130 is located directly above the freezing liner 120 and is closely adjacent to the upper side portion of the refrigerating liner 110, so that the temperature-changing liner 130 is not only convenient for itself to obtain cooling energy from the cooling chamber 123, but also can be used as an intermediate air duct to communicate the cooling chamber 123 with the refrigerating air duct 116, so that the refrigerating liner 110 can set the refrigerating air duct 116 at a higher position to supply air from top to bottom. Therefore, the refrigerator 1 can eliminate the traditional long and narrow air supply duct connected between the cooling chamber 123 and the higher position of the refrigerating air duct 116, simplify the air supply structure of the refrigerator 1, and make the air path system of the refrigerator 1 more reasonable.

In addition, for the variable temperature chamber 132, because the actual space requirement is not large, and the air volume requirement of the variable temperature chamber 132 is small (the first air duct 410 can be made smaller to avoid the space of the second air duct 420), the air duct forming member 40 is occupied as an intermediate air duct to connect the cooling chamber 123 and the refrigerating air duct 116, which does not affect the variable temperature chamber 132, and the internal space of the air duct forming member 40 is fully utilized, so that the utilization rate of the air duct forming member 40 is higher, and the structure is more compact.

In this embodiment, since the second air inlet duct 434 and the second air outlet duct 444 together form the second air duct 420, and the second air outlet duct 444 is located at the second lateral side of the air duct forming member 40, the second air outlet duct 444 is adjacent to the refrigerating inner container 110, which facilitates the connection between the second air outlet duct 444 and the refrigerating air duct 116.

In addition, since the first air inlet duct 432 and the second air inlet duct 434 are disposed in the front and rear of the air inlet chamber 430, compared with the transverse arrangement, the variable temperature air inlet 414 as the inlet of the first air duct 410 and the middle air inlet 422 as the inlet of the second air duct 420 can fully utilize the transverse width of the air duct forming member 40, so that the first air inlet duct 432 and the second air inlet duct 434 can be made more flat, and on the basis of obtaining a larger air inlet amount, the front and rear dimensions of the air inlet chamber 430 of the air duct forming member 40 are not excessively increased, so that the internal structure of the air duct forming member 40 is more reasonable.

Temperature-varying air outlet 412 may be formed directly in front wall 452 of air duct front cover 450, or may be formed in air delivery face frame 90 (shown in fig. 7) attached to front wall 452 of air duct front cover 450.

The intermediate air outlet 424 may be disposed adjacent the lateral second side wall 456, the duct rear cover 460 proximate the lateral second side, or at the intersection of the lateral second side wall 456 and the duct rear cover 460 (as shown in fig. 6 and 8) via the gasket 54 (as shown in fig. 6 and 7).

In some embodiments, the duct front cover 450 may be made of foam to achieve better thermal insulation and lighter weight. The duct rear cover 460 may also be made of PE film for better sealing and economy.

That is, when the lower side of the duct front cover 450 serves as the air inlet portion 458a, the upper side serves as the air outlet portion 458b. When the duct rear cover 460 covers the duct front cover 450, the air inlet cavity 430 is enclosed by the lower area of the duct rear cover 460, the two side walls 456 of the air inlet 458a and the front wall 452 of the air inlet 458a, and the air outlet cavity 440 is enclosed by the upper area of the duct rear cover 460, the two side walls 456 of the air outlet 458b, the front wall 452 of the air outlet 458b and the top wall 454 of the air outlet 458b.

The partition ribs 459 may be formed on the rear surface of the front wall 452 of the air outlet portion 458b and extend substantially from top to bottom, such that the partition ribs 459 partition the air outlet chamber 440 into a first air outlet channel 442 on a first lateral side and a second air outlet channel 444 on a second lateral side.

Referring to fig. 7 to 11, fig. 11 is a schematic view of a duct forming medium intake air partition 470 of the refrigerator 1 according to an embodiment of the present invention. Further, the air duct forming member 40 may further include an air inlet partition 470, wherein the air inlet partition 470 is disposed in the air inlet cavity 430 and connected to the bottom of the first air outlet duct 442, so as to define, with the air inlet portion 458a, a first air inlet duct 432 communicating with the first air outlet duct 442.

Referring to fig. 11, the air inlet partition 470 may include a main body 472 and two side walls 474, and the two side walls 456 are formed at both lateral side edges of the main body 472 and extend forward.

Referring to fig. 9, the main body 472 is disposed opposite to the front wall 452 of the air inlet portion 458a in a spaced manner, and the two side wall portions 474 abut against the rear surfaces of the front walls 452 of the air inlet portion 458a, respectively, so that the main body 472, the two side wall portions 474 and the front wall 452 of the air inlet portion 458a define the first air inlet duct 432.

Referring to fig. 8, 10 and 11, in addition, the upper end surface 474a of the sidewall part 474 on the second lateral side abuts against the lower end surface 459a of the partition rib 459, so that the first air inlet duct 432 is completely sealed from the first air outlet duct 442, and the refrigerant air is prevented from flowing into the second air outlet duct 444 from the gap between the sidewall part 474 on the second lateral side and the lower end surface 459a of the partition rib.

Referring to fig. 7 to 9, further, the duct forming member 40 may further include an air inlet sealing member 480, and the air inlet sealing member 480 is disposed in the air inlet chamber 430 on a side of the air inlet partition 470 facing away from the air inlet portion 458a, so as to define a second air inlet duct 434 communicating with the second air outlet duct 444 together with the air inlet partition 470 and a second lateral side of the air inlet portion 458 a.

The intake air seal 480 is disposed opposite the intake air partition 470, and the lateral width of the intake air seal 480 may match the lateral width of the entire intake air chamber 430.

Since the air inlet partition 470 is located at a first lateral side of the air inlet chamber 430, the second air inlet duct 434 can be formed of two parts distributed laterally. The first portion is located at a lateral first side, defined by a front surface of the intake air seal 480 and a rear surface of the intake air partition 470; the second portion is located on a second lateral side and is bounded by the rear surface of the intake air seal 480, the side wall 456 of the second lateral side of the intake portion 458a, and the front wall 452 of the intake portion 458 a.

Since the air inlet partition 470 is located at the first lateral side, the refrigerant air flow entering the first portion from the middle air inlet 422 needs to flow laterally to the second side to enter the second portion, and finally flows upward from the second portion to the second air outlet channel 444. The second portion of the refrigerant flow from the middle inlet 422 may then directly enter the second outlet channel 444.

Therefore, the inlet of the first portion and the inlet of the second portion together constitute the middle inlet 422 of the second inlet duct 434, which realizes the function of enlarging the middle inlet 422. That is, this embodiment has not only realized two air outtake that transversely parallel, has realized two air inlet ducts that parallel around having moreover.

Referring to fig. 7 and 10, further, the inlet partition 470 is hermetically connected to the upper edge and the first lateral side of the inlet seal 480, so that the refrigerant flow entering the first portion from the middle inlet 422 does not flow into the first outlet channel 442.

In some embodiments, the air inlet partition 470 and the air inlet seal 480 may be sealed by a positive fit connection.

For example, the front wall 452 of the intake air seal 480 is provided with raised ribs 482 at a lateral first side and a top portion thereof, while the intake partition 470 is formed with recessed regions 476 on a rear wall of the body portion 472 that mate with the raised ribs 482, the raised ribs 482 mating with the recessed regions 476 to seal the upper edge as well as the lateral first side.

Referring to fig. 9, further, the rear surface of the air intake seal 480 is flush with the rear end surface 459b of the partition rib 459.
