[0046] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0047] At present, household refrigeration equipment usually includes multiple storage compartments. For example, household refrigerators usually include a refrigerator and a freezer to store different foods. Refrigeration equipment is usually provided with a refrigeration assembly. When the refrigeration equipment includes multiple storage compartments, the refrigeration assembly is usually arranged at the back of the freezer, so that the low-temperature gas produced by the refrigeration assembly cannot directly enter the refrigerator. For this reason, a guide is usually arranged between the refrigeration assembly and the refrigerator, and the low-temperature gas produced by the refrigeration assembly is transported to the refrigerator by the guide, and the relatively high temperature gas in the refrigerator is transported to the refrigeration assembly by the guide, so as to realize air cooling circulation. The current guide member is usually an integrally formed component, and the guide member is provided with a first guide hole and a second guide hole, wherein the first guide hole is used to connect the supply air duct between the refrigeration component and the cold storage room, and the second guide hole is used to connect the return air duct between the cold storage room and the refrigeration component. However, when the guide member is connected to the refrigeration component and the cold storage room, in order to avoid the filling of thermal insulation foam material to block the above-mentioned supply air duct and / or return air duct, it is necessary to seal the connection position between the guide member and the refrigeration component, and the connection position between the guide member and the cold storage room, that is, the outer ring of the guide member is sealed to the outer wall of the storage compartment, and the outer ring of the guide member is sealed to the outer wall of the refrigeration component, which makes it difficult to detect whether there is a cross-flow phenomenon between the above-mentioned first guide hole and the second guide hole. When there is a cross-flow phenomenon, part of the low-temperature gas that should enter the cold storage room returns to the refrigeration component via the return air duct, which eventually leads to a decrease in the refrigeration efficiency of the refrigeration equipment.

[0048] The present disclosure provides an air cooling circulation system. Figures 1 to 3 As shown, the air cooling circulation system includes a refrigeration component 1, a storage compartment 2 and a flow guide component 3.

[0049] Among them, the refrigeration component 1 has a first air outlet 11 and a first air inlet 12, the storage compartment 2 has a second air outlet 21 and a second air inlet 22, the guide component 3 includes an air supply component 31 and an air return component 32, the two ends of the air supply component 31 are respectively connected to the first air outlet 11 and the second air inlet 22, and the two ends of the return air component 32 are respectively connected to the second air outlet 21 and the first air inlet 12.

[0050] In this way, the guide assembly 3 includes two independent components, the air supply member 31 and the return air member 32. The two ends of the air supply member 31 are respectively connected to the first air outlet 11 and the second air inlet 22 to form an air supply channel, and the two ends of the return air member 32 are respectively connected to the second air outlet 21 and the first air inlet 12 to form a return air channel. After the assembly is completed, the air tightness of the two channels can be tested separately to avoid cross-flow between the supply air channel and the return air channel, thereby ensuring that the refrigeration equipment has a higher refrigeration efficiency.

[0051] Below, each component in the air cooling circulation system is introduced separately:

[0052] 1. Refrigeration components 1

[0053] The refrigeration component 1 is a component in the air-cooled circulation system used for exchanging heat with the circulating gas to reduce the gas temperature.

[0054] like Figure 2 As shown, the refrigeration assembly 1 has a first air outlet 11 and a first air inlet 12. In practice, low-temperature gas leaves the refrigeration assembly 1 through the first air outlet 11 and flows to the storage compartment 2, and higher-temperature gas enters the refrigeration assembly 1 through the first air inlet 12 to exchange heat with the refrigeration assembly 1.

[0055] In some possible embodiments, Figure 5 As shown, the refrigeration assembly 1 has a first wall surface 13, and the storage compartment 2 has a second wall surface 23, and the first wall surface 13 is arranged opposite to the second wall surface 23. The first air outlet 11 and the first air inlet 12 are both located on the first wall surface 13, and the second air outlet 21 and the second air inlet 22 are both located on the second wall surface 23, and the first air outlet 11 and the second air inlet 22 are arranged opposite to each other, and the first air inlet 12 and the second air outlet 21 are arranged opposite to each other.

[0056] In this way, the length of the air supply component 31 and the air return component 32 can be reduced, thereby reducing the processing cost and improving the convenience of assembly.

[0057] In one example, see Figure 3 The second air outlet 21 includes two through-hole structures, which are respectively connected to different areas of the refrigerating chamber. In this way, zoned refrigeration can be achieved.

[0058] Optionally, the apertures of the two through holes may be different. In this way, different areas in the refrigerating chamber may be at different temperatures according to the size relationship of the apertures.

[0059] In one example, if Figure 5 As shown, the first wall surface 13 of the refrigeration component 1 includes a first step surface 131 , a transition surface 132 and a second step surface 133 . The first air outlet 11 is located on the first step surface 131 , and the first air inlet 12 is located on the second step surface 133 .

[0060] In practice, the two ends of the air supply member 31 are sealedly connected to the refrigeration component 1 and the storage compartment 2 respectively, and the two ends of the air return member 32 are sealedly connected to the refrigeration component 1 and the storage compartment 2 respectively. When the above-mentioned sealing connection fails, since the first step surface 131 and the second step surface 133 are located in different planes, that is, the second step surface 133 has a convex structure relative to the first step surface 131, the wind resistance between the first step surface 131 and the second step surface 133 can be increased, and the air flow from the first air outlet 11 to the first air inlet 12 can be reduced, thereby ensuring that the refrigeration equipment has a higher refrigeration efficiency.

[0061] Optionally, the first step surface 131 and the second step surface 133 are parallel, and there is a smooth transition between the first step surface 131 and the transition surface 132. In this way, the processing difficulty between the first step surface 131 and the second step surface 133 can be reduced.

[0062] In one example, if Figure 6 As shown, the air supply member 31 can be in contact with the transition surface 132 .

[0063] In implementation, the air supply member 31 can be aligned with the transition surface 132 and the transition surface 132 can be used as a positioning reference surface when the air supply member 31 is assembled, thereby reducing the assembly difficulty of the air supply member 31 and improving the assembly accuracy.

[0064] In some possible embodiments, the refrigeration assembly 1 includes a housing 101 , a heat exchanger 102 , and a fan 103 .

[0065] Housing 101

[0066] The housing 101 is a component in the refrigeration assembly 1 for accommodating the heat exchanger 102 and the fan 103 .

[0067] like Figure 7 ( Figure 7 1 is a partial cross-sectional view of the refrigeration assembly 1, the housing 101 has a plate-like structure, and has a housing cavity therein, which is used to accommodate components of the heat exchanger 102 and the fan 103. A first air outlet 11 and a first air inlet 12 are provided on the top wall of the housing 101, and the first air outlet 11 and the first air inlet 12 are connected to the housing cavity.

[0068] The housing 101 can be formed by a stamping process or a casting process, which is not limited in the present embodiment. The housing 101 can be made of aluminum or stainless steel, which is not limited in the present embodiment.

[0069] Heat exchanger 102

[0070] The heat exchanger 102 is a component in the refrigeration assembly 1 for exchanging heat with air.

[0071] like Figure 7 As shown, the heat exchanger 102 is located in the accommodating cavity of the shell 101 and is connected to the shell 101 .

[0072] During implementation, air with a higher temperature flows to the vicinity of the heat exchanger 102 through the first air inlet 12. Refrigerant flows in the heat exchanger 102. The surface temperature of the heat exchanger 102 is relatively low. The temperature of the air with a higher temperature decreases after heat exchange with the heat exchanger 102, and then flows to the storage room 2 through the first air outlet 11.

[0073] Exemplarily, the heat exchanger 102 may be a plate heat exchanger, so that the heat exchange area between the air and the heat exchanger 102 can be increased, thereby improving the heat exchange efficiency.

[0074] Fan 103

[0075] The fan 103 is a component in the refrigeration assembly 1 for promoting air flow.

[0076] like Figure 7 As shown, the fan 103 is located in the accommodating cavity of the shell 101, between the top wall and the heat exchanger 102, and connected to the shell.

[0077] During implementation, the fan 103 rotates to push the low-temperature gas toward the first air outlet 11, so that the low-temperature gas flows to the storage compartment 2 through the first air outlet 11, and forms a negative pressure in the accommodating cavity of the shell 101. Under the action of the negative pressure, the gas with a higher temperature is sucked into the accommodating cavity through the first air inlet 12 to exchange heat with the heat exchanger 102, thereby realizing an air-cooled cycle.

[0078] 2. Storage room 2

[0079] The storage compartment 2 is a component in the refrigeration device for accommodating objects.

[0080] like Figure 3 As shown, the storage compartment 2 has a cubic structure, and a cavity structure with an open end is arranged inside the cubic structure, and the cavity structure is used to accommodate objects to be stored.

[0081] In some possible embodiments, the refrigeration device includes a plurality of storage compartments 2 .

[0082] like Figure 8As shown, the refrigeration device includes a first storage compartment 201 and a second storage compartment 202, the first storage compartment 201 is located above the second storage compartment 202, the first storage compartment 201 and the second storage compartment 202 both have a cubic structure, the first storage compartment 201 and the second storage compartment 202 are both provided with a cavity structure with one end open, and the opening directions of the first storage compartment 201 and the second storage compartment 202 are the same, and these cavity structures are used to accommodate objects to be stored.

[0083] In the implementation, taking a refrigerator as an example, the refrigerator is usually provided with a refrigerating chamber and a freezing chamber, and the refrigerating chamber and the freezing chamber correspond to the first storage compartment 201 and the second storage compartment 202, respectively. Figure 8 The refrigerator includes a first storage compartment 201 and a second storage compartment 202, and there is a gap between the first storage compartment 201 and the second storage compartment 202. The refrigeration component 1 is located at an end of the second storage compartment 202 away from the opening and is connected to the second storage compartment 202. Since there is a gap between the refrigeration component 1 and the first storage compartment 201, the low-temperature gas discharged by the refrigeration component 1 cannot directly enter the first storage compartment 201. Therefore, a flow guide component 3 is required to connect the first storage compartment 201 with the refrigeration component 1.

[0084] The materials of the first storage compartment 201 and the second storage compartment 202 can be the same or different. For example, both are made of engineering plastics, or the first storage compartment 201 is made of glass and the second storage compartment 202 is made of engineering plastics, which is not limited in the embodiment of the present disclosure. The first storage compartment 201 and the second storage compartment 202 can be formed by a vacuum forming process or an injection molding process, which is not limited in the embodiment of the present disclosure.

[0085] 3. Diversion component 3

[0086] The flow guide component 3 is a component used for guiding gas in the refrigeration equipment. The flow guide component 3 includes an air supply component 31 and an air return component 32. The two ends of the air return component 32 are connected to the second air outlet 21 and the first air inlet 12 respectively.

[0087] Air supply 31

[0088] The air supply member 31 is a component in the air guide assembly 3 for guiding low-temperature gas from the refrigeration assembly 1 to the storage compartment 2 .

[0089] like Figure 1 As shown, two ends of the air supply member 31 are connected to the first air outlet 11 and the second air inlet 22 respectively.

[0090] In some possible embodiments, the air supply member 31 includes a first air guide portion 311, a first connecting portion 312 and a second connecting portion 313 that are connected to each other. The two ends of the first air guide portion 311 are respectively connected to the first air outlet 11 and the second air inlet 22. The first connecting portion 312 is connected to the refrigeration assembly 1, and the second connecting portion 313 is connected to the storage compartment 2.

[0091] like Figure 4 As shown, the first air guide portion 311 has a columnar structure, and has a guide passage (not shown) with two ends connected therein. The two ends of the first air guide portion 311 are respectively connected to the first air outlet 11 and the second air inlet 22, that is, the guide passage connects the first air outlet 11 and the second air inlet 22. The first connecting portion 312 and the second connecting portion 313 both have an annular plate structure. The first connecting portion 312 is located on a side of the first air guide portion 311 close to the refrigeration assembly 1 and is connected to the outer wall of the first air guide portion 311. The second connecting portion 313 is located on a side of the first air guide portion 311 close to the storage compartment 2 and is connected to the outer wall of the first air guide portion 311.

[0092] In one example, the first air guide portion 311, the first connecting portion 312 and the second connecting portion 313 are integrally formed, so that the overall strength of the air supply member 31 can be improved.

[0093] In an example, the outer wall of the first air guide portion 311 has a first reinforcing rib 3112 .

[0094] like Figure 4 As shown, the outer wall of the first air guide 311 has a plurality of first reinforcing ribs 3112, and the plurality of first reinforcing ribs 3112 are distributed in a matrix. In this way, the overall strength of the air supply member 31 can be improved, and after the sealing connection, the sealing failure caused by the deformation of the first air guide 311 can be avoided, thereby avoiding the reduction of the refrigeration efficiency of the refrigeration equipment.

[0095] In one example, the air supply member 31 is connected to the refrigeration assembly 1 and the storage compartment 2 by bonding. Figure 4 As shown, the first connection portion 312 is bonded to the outer wall of the refrigeration assembly 1 , and the second connection portion 313 is bonded to the outer wall of the storage compartment 2 .

[0096] Optionally, the first connection part 312 and the second connection part 313 may both have an L-shaped structure, the bottom edge of the first connection part 312 close to the first air guide part 311 is bonded to the first wall surface 13 of the refrigeration component 1, the side edge of the first connection part 312 away from the first air guide part 311 is bonded to the outer wall of the back plate of the refrigeration component 1, the bottom edge of the second connection part 313 close to the first air guide part 311 is bonded to the second wall surface 23 of the storage compartment 2, and the side edge of the second connection part 313 away from the first air guide part 311 is bonded to the outer wall of the back plate of the storage compartment 2. In this way, the connection strength between the air supply part 31 and the refrigeration component 1 and the storage compartment 2 can be improved.

[0097] Return air 32

[0098] The air return member 32 is a component in the air guide assembly 3 for guiding relatively high temperature gas from the storage compartment 2 to the refrigeration assembly 1 .

[0099] like Figure 1 As shown, two ends of the air return member 32 are respectively connected to the second air outlet 21 and the first air inlet 12 .

[0100] In some possible embodiments, the return air member 32 includes a second air guide portion 321, a third connection portion 322 and a fourth connection portion 323 which are connected to each other. The two ends of the second air guide portion 321 are respectively connected to the second air outlet 21 and the first air inlet 12. The third connection portion 322 is connected to the refrigeration assembly 1. The fourth connection portion 323 is connected to the storage compartment 2.

[0101] like Figure 4 As shown, the second air guide portion 321 has a columnar structure, and has a guide passage (not shown) with two ends connected therein. The two ends of the second air guide portion 321 are respectively connected to the second air outlet 21 and the first air inlet 12, that is, the guide passage connects the second air outlet 21 and the first air inlet 12. The third connecting portion 322 and the fourth connecting portion 323 both have an annular plate structure. The third connecting portion 322 is located on a side of the second air guide portion 321 close to the refrigeration assembly 1 and is connected to the outer wall of the second air guide portion 321. The fourth connecting portion 323 is located on a side of the second air guide portion 321 close to the storage compartment 2 and is connected to the outer wall of the second air guide portion 321.

[0102] In one example, the second air guide portion 321, the third connection portion 322 and the fourth connection portion 323 are integrally formed, so that the overall strength of the air return member 32 can be improved.

[0103] In an example, the outer wall of the second air guide portion 321 has a second reinforcing rib 3212 .

[0104] like Figure 4As shown, the outer wall of the second air guide 321 has a plurality of second reinforcing ribs 3212, and the plurality of second reinforcing ribs 3212 are arranged in a matrix. In this way, the overall strength of the air return member 32 can be improved, and after the sealing connection, the second air guide 321 can be prevented from deforming and causing sealing failure, thereby preventing the refrigeration efficiency of the refrigeration equipment from decreasing.

[0105] In one example, the air return member 32 is connected to the refrigeration assembly 1 and the storage compartment 2 by bonding. Figure 4 As shown, the third connection portion 322 is bonded to the outer wall of the refrigeration assembly 1 , and the fourth connection portion 323 is bonded to the outer wall of the storage compartment 2 .

[0106] Optionally, the third connection part 322 and the fourth connection part 323 may both have an L-shaped structure, the bottom edge of the third connection part 322 close to the second air guide part 321 is bonded to the first wall surface 13 of the refrigeration assembly 1, the side edge of the third connection part 322 away from the second air guide part 321 is bonded to the back plate outer wall of the refrigeration assembly 1, the bottom edge of the fourth connection part 323 close to the second air guide part 321 is bonded to the second wall surface 23 of the storage compartment 2, and the side edge of the fourth connection part 323 away from the second air guide part 321 is bonded to the back plate outer wall of the storage compartment 2. In this way, the connection strength between the return air part 32 and the refrigeration assembly 1 and the storage compartment 2 can be improved.

[0107] Exemplarily, the air supply member 31 and the air return member 32 may be bonded to the refrigeration assembly 1 and the storage compartment 2 by using double-sided adhesive tape.

[0108] In one example, the first guide portion 311 and the second guide portion 321 both have a rectangular cylindrical structure, and the first side wall 3111 of the first guide portion 311 and the second side wall 3211 of the second guide portion 321 are parallel, and the first side wall 3111 is arranged opposite to the second side wall 3211. In this way, the assembly of the guide assembly 3 can be made more compact.

[0109] In one example, if Figure 1 As shown, there is an air avoidance area 100 between the air supply member 31 and the air return member 32. The specific width of the air avoidance area 100 can be set according to actual needs, and the embodiment of the present disclosure does not limit this. In this way, it is possible to detect whether there is a cross-flow phenomenon between the air supply member 31 and the air return member 32 in the air avoidance area 100, thereby avoiding a decrease in the refrigeration efficiency of the refrigeration equipment due to the cross-flow phenomenon. At the same time, the split air supply member 31 and the air return member 32 are used to connect the air supply flow channel and the return air flow channel respectively, which can reduce the difficulty of assembling the guide component 3.

[0110] In implementation, the guide component 3 is configured as an independent air supply component 31 and a return air component 32. When the structure of the first air outlet 11 and / or the second air inlet 22 corresponding to the air supply channel changes, or the structure of the first air inlet 12 and / or the second air outlet 21 corresponding to the return air channel changes, the guide components corresponding to the unchanged channels can continue to be used, and there is no need to completely replace the guide component, thereby reducing the manufacturing cost of the guide component 3.

[0111] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0112] The disclosed embodiment provides an air-cooling circulation system, in which the air guide component 3 includes an air supply member 31 and an air return member 32. The two ends of the air supply member 31 are respectively connected to the first air outlet 11 and the second air inlet 22, and the two ends of the air return member 32 are respectively connected to the second air outlet 21 and the first air inlet 12. In this way, the air guide component 3 includes two independent components, the air supply member 31 and the air return member 32.
