As shown in Figure 14 , the opening size of the second air outlet 3122 in the height direction is smaller than the opening size of the first air outlet 3121 in the height direction. In this embodiment, there is a distance between the second air outlet 3122 and the lower end surface of the air mixing structure 30.

[0062] When the second chamber 11 is provided with a functional area 112, the air outlet 312 further comprises a third air outlet 3123 located on the lower side of the second air outlet 3122 in the height direction, and the third air outlet 3123 is arranged open towards the lower side. In addition, the refrigeration device 100 further has an air guide pipe 75 connected to the third air outlet 3123.

[0063] The air mixing structure 30 further has a partition wall 34 located between the front wall 31 and the rear wall 32 in the front-rear direction, and the partition wall 34 is located on the side of the air mixing structure 30 close to the cooling chamber 20 and separates the second air supply air duct 4 and the air inlet air duct 5.

[0064] The second air supply air duct 4 is located on the rear side of the air inlet air duct 5, and the second air supply air duct 4 comprises a first air supply section 41 connecting the air mixing structure 30 and the cooling chamber 20, and a second air supply section 42 formed on the air mixing structure 30. The second air supply section 42 is defined by the partition wall 34 and the rear wall 32, and the side end surface of the partition wall 34 close to the cooling chamber 20 is not flush with the side end surface of the rear wall 32 close to the cooling chamber 20, and the side end surface of the partition wall 34 close to the cooling chamber 20 is arranged closer to the cooling chamber 20 than the side end surface of the rear wall 32 close to the cooling chamber 20, that is, the partition wall 34 extends beyond the side end surface of the rear wall 32 towards the cooling chamber 20 in the left-right direction, so that the partition wall 34 has a stepped portion 3412 protruding from the rear wall 32.

[0065] Specifically, the partition wall 34 comprises a first flat wall 341, a connecting wall 342 and a second flat wall 343 connected in sequence, the step portion 3412 is formed at the end portion of the first flat wall 341 and is located at the side of the first flat wall 341 away from the connecting wall 342.

[0067] The first air supply section 41 comprises a flat section 411 connected with the second air supply section 42 and an inclined section 412 connecting the flat section 411 with the cooling chamber 20, the end of the inclined section 412 connected with the cooling chamber 20 is located in front of the end thereof connected with the flat section 411 in the front-rear direction, so that the flat section 411 is located at the rear side of the refrigeration air supply port of the cooling chamber 20.

[0068] The rear wall 32 is provided with a recessed portion 321 recessed from the front surface thereof towards the rear side at the side close to the cooling chamber 20, the recessed portion 321 is spaced apart from the end surface of the rear wall 32 close to the cooling chamber 20 in the left-right direction, and the recessed portion 321 is arranged corresponding to the second flat wall 343 in the front-rear direction, so as to avoid the problem that the second air supply section 42 is narrowed at this position due to the rearward bias of the second flat wall 343. The front-rear opening size of the second air supply section 42 at the position adjacent to the first air supply section 41 is the largest, so as to facilitate receiving the cold air sent from the first air supply section 41.

[0071] As shown in Figures 10-13 The air mixing structure 30 further has a partition 35 inside the air mixing area 301 and connecting the front wall 31 and the rear wall 32, the partition 35 divides the air mixing area 301 into a first mixing area 3011 and a second mixing area 3012, and the first mixing area 3011 and the second mixing area 3012 are in communication at the side close to the cooling chamber 20.

[0072] Further, the partition 35 has a protruding part 351 protruding towards the second air supply duct 4. In this embodiment, the protruding part 351 is arranged close to the bottom end of the air mixing structure 30 in the height direction, so that the accommodation space of the first mixing area 3011 is larger than that of the second mixing area 3012.

[0073] The partition 35 has a first side edge 352 and a second side edge 353 arranged opposite in the height direction, and the first and second side edges 352, 353 are both concave arc-shaped, so that the mixing space on both sides of the partition 35 is larger.

[0074] As shown in Figure 15 The first air outlet 3121 is in communication with the first mixing area 3011 in the front-rear direction, and the second air outlet 3122 is in communication with the second mixing area 3012 in the front-rear direction.

[0075] The second mixing area 3012 comprises a second vertical passage 3015 having an upper side and extending vertically, a narrowed passage 3016 located at the lower side and communicating with the second air outlet 3122, the narrowed passage 3016 communicates with the second air outlet 3122 forwardly and with the third air outlet 3123 downwardly, and the upper part of the narrowed passage 3016 has a larger opening size in the front-rear direction than the lower part.

[0076] Further, as shown in the drawings, Figures 1-4 In some embodiments of the present application, the refrigeration equipment 100 is of a double-door structure, the cooling chamber 20 is arranged at the upper side of the back of the first compartment 12, and the air mixing area 301 is arranged at the upper part of the back of the second compartment 11.

[0077] The air mixing structure 30 further has a drain groove 36 located at the lower side and penetrating the air mixing structure 30 in the up-down direction to drain the condensation formed in the air mixing area outwardly.

[0078] In addition, the air mixing structure 30 further has an inclined surface 302 located at the lower side and arranged at an angle with the vertical surface, and the outlet end of the drain groove 36 is arranged on the inclined surface 302. In this way, the opening of the outlet end of the drain groove 36 is enlarged, thereby facilitating the water to be drained out quickly.

[0079] In some embodiments of the present application, the drain groove 36 communicates with the air inlet duct 5, and the projection of the drain groove 36 on the horizontal plane falls within the projection of the air inlet duct 5 on the horizontal plane. The drain groove 36 is located at the side of the second air outlet 3122 close to the cooling chamber 20 in the left-right direction, and the lower end edge of the drain groove 36 on the inclined surface 302 is located at the lower side of the second air outlet 3122. In addition, the second air outlet 3122 is located within the extension range of the inclined surface 302 in the height direction.

[0080] In some embodiments of the present application, the refrigeration system of the refrigeration equipment 100 is a single refrigeration system composed of one evaporator 21 and one fan 22, and through the connection of the air ducts, each temperature zone can be refrigerated separately, and the temperature in each compartment is more uniform and the temperature fluctuation is smaller through the refrigeration, refrigeration and multi-path air supply ducts. In addition, the fan 22 works intermittently, and when the fan 22 operates normally, it blows the cold air in the cooling chamber 20 into the second compartment 11 and the first compartment 12.

[0081] The refrigeration return air pipe 71 returns the air in the second compartment 11 to the cooling chamber 20, and the refrigeration return air pipe 71 is arranged in the middle beam 13.

[0082] The refrigeration return air duct 71 has a main duct 711 extending along the height direction and a connecting duct 712 connected to the top end of the main duct 711. The return air outlet 7101 is arranged at the end of the connecting duct 712 connected to the cooling chamber 20. The connecting duct 712 is arranged at an angle with the main duct 711.

[0083] The refrigeration return air duct 71 has a main duct 711 extending along the height direction and a connecting duct 712 connected to the top end of the main duct 711. The return air outlet 7101 is arranged at the end of the connecting duct 712 connected to the cooling chamber 20. The connecting duct 712 is arranged at an angle with the main duct 711.

[0084] As shown in Figure 4 , Figure 7 and Figure 8 , the connecting duct 712 is arranged at an angle with the main duct 711. The end of the connecting duct 712 connected to the main duct 711 is higher than the end of the connecting duct 712 connected to the cooling chamber 20. In this way, the water vapor in the connecting duct 712 can flow downward into the water pan below the evaporator 21, avoiding flowing into the second chamber 11.

[0085] In addition, the refrigeration return air duct 71 also has a branch duct 713 extending from the main duct 711. The connecting duct 712 and the branch duct 713 are arranged on the left and right sides of the main duct 711. When the fan 22 is normally operated, the air in the second chamber 11 enters the branch duct 713 and the main duct 711 through the auxiliary return air inlet 7103 of the branch duct 713 and the return air inlet 7102 of the main duct 711, and then flows into the cooling chamber 20.

[0086] As shown in Figure 8 , in some embodiments of the present application, the second chamber 11 does not need to be provided with a functional area 112. In this case, the connecting part of the connecting duct 712 and the main duct 711 is provided with a baffle 714 protruding upward. The baffle 714 is located inside the refrigeration return air duct 71 to partially separate the connecting duct 712 and the main duct 711.

[0087] Further, the baffle 714 protrudes upward from the wall of the refrigeration return air duct 71 and extends along the front and back directions. In this way, when the second chamber 11 is not provided with a functional area 112 and when the fan 22 stops operating, the baffle 714 can prevent the cold air in the cooling chamber 20 from flowing into the refrigeration return air duct 71 when the evaporator 21 defrosts.

[0088] As shown in Figure 9As shown, in some other embodiments of the present application, the second chamber 11 is provided with a functional area 112, and in this case, the connecting pipe 712 of the refrigerated return air pipe 71 does not need to be provided with a baffle or similar structure, and when the evaporator 21 defrosts and the fan 22 stops running, the cool air in the cooling chamber 20 can sink from the refrigerated return air pipe 71 and be sent to the functional area 112 located at the lower part of the second chamber 11.

[0089] That is, when the second chamber 11 is provided with a functional area 112, and when the fan 22 stops running, the cooled cool air in the cooling chamber 20 flows into the lower part of the second chamber 11 through the refrigerated return air pipe 71.

[0090] The refrigeration equipment 100 also has a drain pipe 74 connected to the cooling chamber 20 to drain water in the cooling chamber 20, and the refrigerated return air pipe 71 is arranged close to the drain pipe 74. The water inlet of the drain pipe 74 is lower than the height of the return air outlet 7101 of the refrigerated return air pipe 71 in the height direction.

[0091] In the embodiment as shown in Figures 3-6 In one embodiment, the refrigerated return air pipe 71 and the drain pipe 74 are arranged independently and side by side, and the drain pipe 74 extends downward beyond the bottom end of the refrigerated return air pipe 71.

[0092] In another embodiment as shown in Figure 9 and Figure 17 The drain pipe 74 extends into the refrigerated return air pipe 71 and includes a first drain section 741 located on the upper side and a second drain section 742 located on the lower side, the first drain section 741 connects the cooling chamber 20 and the refrigerated return air pipe 71, and the second drain section 742 extends downward from the bottom end of the refrigerated return air pipe 71. The first drain section 741 and the refrigerated return air pipe 71 are connected on the side close to the cooling chamber 20 in the left-right direction.

[0093] In the present application, the refrigeration equipment 100 is arranged by arranging the first return air duct 72 connected to the first chamber 12 on the front side of the cooling chamber 20 and extending downward beyond the cooling chamber 20, so that the air is uniformly sent along the wall surface of the first chamber 12, the pipe layout is reasonable, and the cold energy can be uniformly and effectively utilized.
