[0040] The refrigeration equipment has a plurality of air duct modules to supply air to different chambers, and each air duct module can be configured with a set of refrigeration components to realize gas refrigeration. For a single system refrigeration equipment, refrigeration components can also be arranged in only one air duct module, and the air duct is connected in communication with other air ducts to realize air supply of a set of refrigeration components for a plurality of air duct modules. However, in the related art, two air ducts are directly connected in communication to realize air supply, and the size of the air duct module is large, and the direct connection operation is relatively inconvenient.

[0041] In order to solve the problems in the related art to some extent, the application provides a switching air duct, an air duct module and a refrigeration equipment. In the docking process, the positions of the air supply air duct and the air outlet air duct do not need to be moved, only the position of the switching air duct is adjusted, so that the air supply air duct and the air outlet air duct are accurately connected in communication, thereby greatly improving the convenience of docking the air supply air duct and the air outlet air duct.

[0042] The application will be described below in conjunction with the drawings and specific embodiments:

[0043] Please refer to Figure 1 and Figure 2 The application provides a switching air duct 300 applied to an air duct module 200 of a refrigeration equipment 10. The refrigeration equipment 10 has an air supply air duct 110, and the air duct module 200 has an air outlet air duct 220. The air supply air duct 110 and the air outlet air duct 220 are used to supply air to a chamber 140 of the refrigeration equipment 10. The switching air duct 300 provided by the application can accurately connect the air supply air duct 110 and the air outlet air duct 220 in communication during the docking process of the air outlet air duct 220 and the air supply air duct 110, without moving the positions of the air supply air duct 110 or the air outlet air duct 220. Only the position of the switching air duct 300 is adjusted, so that the air supply air duct 110 and the air outlet air duct 220 are accurately connected in communication, thereby greatly improving the convenience of docking the air supply air duct 110 and the air outlet air duct 220.

[0044] The refrigeration equipment 10 can be a refrigerator or a freezer. In the application, the refrigeration equipment 10 is taken as a refrigerator for convenience of description. When the refrigeration equipment 10 is other equipment, it can be taken by analogy.

[0045] The refrigeration equipment 10 is generally cuboid, and for the convenience of description, the height direction Z, the width direction X and the thickness direction Y are defined respectively, wherein in the use state of the refrigeration equipment 10, the vertical direction is the height direction Z, and the projection of the refrigeration equipment 10 in the vertical direction is a rectangle. The direction of the long side is the width direction X, and the direction of the wide side is the thickness direction Y.

[0046] Similarly, for the convenience of description, the six directions of up, down, left, right, front and back are defined. Among them, in the height direction Z, close to the top surface 336 is up, and away from the top surface 336 is down. The two directions in the width direction X are left and right respectively. The chamber 140 of the refrigeration equipment 10 has an opening, and the door body 700 is arranged at the opening. In the thickness direction Y, close to the door body 700 is front, and away from the door body 700 is back.

[0047] Please refer to Figures 3-5 In the embodiment of the present application, the adapter air duct 300 includes a cover plate 300a and an adapter 330. The adapter 330 is installed on the cover plate 300a, and the adapter 330 has a transition channel 400. The transition channel 400 has an air inlet end 410 and an air outlet end 420. The air inlet end 410 is used to communicate with the air supply duct 110, and the air outlet end 420 is used to communicate with the air outlet duct 220.

[0048] Please refer to Figure 6 Among them, the cross-sectional width of the air inlet end 410 is greater than the cross-sectional width of the air outlet end 420.

[0049] It should be noted that the cross section described herein refers to the cross section in the thickness direction Y. Since the transition channel 400 has an air inlet end 410 and an air outlet end 420, the air inlet end 410 is used to communicate with the air supply duct 110, and the air outlet end 420 is used to communicate with the air outlet duct 220, so that the air supply duct 110 and the air outlet duct 220 can be communicated. When the air outlet duct 220 and the air supply duct 110 are docked, the air supply duct 110 and the air outlet duct 220 can be communicated through the transition channel 400 to realize the communication between the air supply duct 110 and the air outlet duct 220, that is, during the docking process, the position of the entire air duct module 200 does not need to be moved, only the position of the adapter air duct 300 needs to be adjusted, so that the air supply duct 110 and the air outlet duct 220 can be accurately communicated, thereby greatly improving the convenience of docking the air supply duct 110 and the air outlet duct 220.

[0050] The air inlet end 410 and the air outlet end 420 are arranged at opposite ends of the transition channel 400, the cross-sectional width of the air inlet end 410 is greater than that of the air outlet end 420, that is, the cross-sectional width of the air inlet end 410 is greater, and the cross-sectional width of the air outlet end 420 is smaller. The cross-sectional width of the air inlet end 410 is greater, which can ensure that the cold air in the air supply duct 110 can enter the transition channel 400 as much as possible when the air supply duct 110 is connected, so that the amount of cold air in the air outlet duct 220 is sufficient, and the cross-sectional width of the air outlet end 420 is smaller, which can accelerate the flow rate of the cold air when entering the air outlet duct 220 from the transition channel 400, and improve the air supply efficiency.

[0051] In some embodiments, along the direction from the air supply duct 110 to the air outlet duct 220, the cross-sectional width of the transition channel 400 changes from wide to narrow.

[0052] The direction from the air supply duct 110 to the air outlet duct 220 is the direction from bottom to top. It should be noted that the cross-sectional width of the transition channel 400 changes from wide to narrow, that is, the cross-sectional width of the transition channel 400 can gradually narrow from wide to narrow, or it can be segmented from wide to narrow, that is, the cross-sectional width of a certain segment of the transition channel 400 can be wider than that of a certain segment below, but the overall cross-sectional width of the transition channel 400 changes from wide to narrow from bottom to top.

[0053] Since the cross-sectional width of the air inlet end 410 is greater than that of the air outlet end 420, the cross-sectional width of the transition channel 400 changes from wide to narrow, which can reduce airflow turbulence, reduce pressure loss, and improve the flow efficiency of the cold air.

[0054] Please refer to Figure 6 and Figure 7 In some embodiments, along the direction from the air supply duct 110 to the air outlet duct 220, the transition channel 400 has a plurality of transition portions 430 arranged in sequence, and the adjacent two transition portions 430 are arc-shaped.

[0055] The adjacent two transition portions 430 are arc-shaped, which can reduce sharp corners and reduce the obstruction of the inner wall of the air outlet duct 220 to the airflow, thereby reducing pressure loss and noise and making the gas flow more smoothly.

[0056] In some embodiments, along the direction from the air supply duct 110 to the air outlet duct 220, each transition portion 430 includes at least a transition segment 431 and a contraction segment 432 arranged in sequence, and the cross-sectional width of the contraction segment 432 changes from wide to narrow.

[0057] For the convenience of description, the two adjacent transitions 430 are respectively named as a first transition 430 and a second transition 430, the second transition 430 is above the first transition 430, wherein the contraction section 432 of the first transition 430 is connected with the transition section 431 of the second transition 430, since the change trend of the cross-sectional width of the contraction section 432 is from wide to narrow, therefore the width of the transition section 431 of the second transition 430 is smaller than the width of the transition section 431 of the second transition 430, and the same applies to the change trend of the cross-sectional width of the transition channel 400, which is from wide to narrow.

[0058] The sudden change of the cross-sectional width of the transition channel 400 will cause the local pressure loss to increase significantly, in the embodiment of the present application, the cross-sectional width of the transition channel 400 is not gradually changed from wide to narrow, but is segmented from wide to narrow, by first keeping the cross-sectional width unchanged, and then gradually narrowing, the sharp change of the gas flow rate can be reduced, thereby reducing the pressure loss along the way.

[0059] Please refer to Figure 5 In some embodiments, the change trend of the cross-sectional width of the adapter 330 is consistent with the change trend of the cross-sectional width of the transition channel 400.

[0060] The change trend of the cross-sectional width of the transition channel 400 is from wide to narrow, that is, the change trend of the cross-sectional width of the adapter 330 is also from wide to narrow. The adapter 330 needs to be used for heat preservation and insulation of the transition channel 400 to reduce the loss of cold, therefore the adapter 330 has a certain thickness, wherein the thickness of the adapter 330 refers to the length between the outer wall and the inner wall of the adapter 330, and the inner wall of the adapter 330 is the inner wall of the transition channel 400.

[0061] The cross-sectional width of the transition channel 400 is related to the thickness of the required adapter 330, that is, the thicker the thickness of the adapter 330 needs to be in the part of the transition channel 400 with wider cross-sectional width, in order to meet the heat preservation requirement, similarly, the thinner the thickness of the adapter 330 needs to be in the part of the transition channel 400 with narrower cross-sectional width. Therefore, the change trend of the cross-sectional width of the adapter 330 is consistent with the change trend of the cross-sectional width of the transition channel 400, that is, the cross-sectional width of the adapter 330 is wider in the part of the transition channel 400 with wider cross-sectional width, so that the thickness of the adapter 330 is thicker, and the cross-sectional width of the adapter 330 is narrower in the part of the transition channel 400 with narrower cross-sectional width, so that the thickness of the adapter 330 is thinner, so that the thickness of the adapter 330 is adapted to the cross-sectional width of the transition channel 400.

[0062] Please refer to Figure 6In some embodiments, the adapter 330 has a bottom surface 335 for interfacing with the air supply duct 110 and a top surface 336 for interfacing with the air outlet duct 220, and the cross-sectional width of the bottom surface 335 is greater than that of the top surface 336.

[0063] The evaporator 120 for cooling air and the flow guide 130 for circulating the cooled air in the chambers 140 can be arranged in the air supply duct 110 to cool the articles in the chambers 140. The air cooled in the air supply duct 110 flows into the air outlet duct 220, so that the air outlet duct 220 supplies air to the chambers 140 of the refrigeration device 10. Since the evaporator 120 and the flow guide 130 need to be installed in the air supply duct 110, and the air outlet duct 220 is only used for air supply, the cross-sectional width of the air supply duct 110 needs to be greater than that of the air outlet duct 220. Since the bottom surface 335 is used to interface with the air supply duct 110 and the top surface 336 is used to interface with the air outlet duct 220, the cross-sectional width of the bottom surface 335 can be greater than that of the top surface 336 to adapt to the sizes of the air supply duct 110 and the air outlet duct 220, respectively.

[0064] It should be noted that the air supply duct 110 and the air outlet duct 220 herein not only include the air ducts themselves, but also the foam pieces forming the air ducts.

[0065] Please refer to Figure 8 and Figure 9 In some embodiments, the cover piece 300a includes a first cover plate 310, a second cover plate 320, and an adapter 330. The first cover plate 310 and the second cover plate 320 form a fixing cavity 321 therebetween; the adapter 330 is located in the fixing cavity 321 and is mounted to the first cover plate 310.

[0066] Since the transition passage 400 communicates with the air outlet duct 220 and the air supply duct 110, and the cooled air is transferred between the air outlet duct 220 and the air supply duct 110, the cooled air passes through the transition passage 400, and in order to reduce the loss of cold energy when the cooled air passes through the transition passage 400, at least part of the adapter 330 needs to be made of a heat-insulating material such as foam, which is relatively fragile. When the air duct module 200 of the refrigeration device 10 is applied, if the adapter 330 is exposed, it is easy to be damaged, so it needs to be protected by the first cover plate 310 and the second cover plate 320.

[0067] The fixing cavity 321 is formed between the first cover plate 310 and the second cover plate 320, that is, the first cover plate 310 and the second cover plate 320 can be connected to form the fixing cavity 321, or the first cover plate 310 and the second cover plate 320 can only be connected or have a spacing, as long as the fixing cavity 321 is formed. The adapter 330 is located in the fixing cavity 321, so that the first cover plate 310 and the second cover plate 320 can protect the adapter 330. The adapter 330 is mounted on the first cover plate 310, that is, the adapter 330 is fixedly connected with the first cover plate 310, so that the position of the adapter 330 is fixed and not easy to move, so as to ensure the precision of the connection between the transition channel 400 and the air outlet duct 220 and the air supply duct 110.

[0068] In some embodiments, the adapter 330 includes an adapter body 332 and a fixing plate 333 arranged on the outer surface of the adapter body 332. The transition channel 400 is arranged in the adapter body 332, and the first cover plate 310 is detachably connected with the fixing plate 333.

[0069] Since the transition channel 400 is arranged in the adapter body 332, in order to reduce the loss of cold energy when the cold air passes through the transition channel 400, the adapter body 332 is made of foam. The fixing plate 333 is arranged on the outer surface of the adapter body 332, that is, the fixing plate 333 can be attached to, abut against, or connected to the outer surface of the adapter body 332. The fixing plate 333 can be arranged on the entire outer surface of the adapter body 332, or can be arranged on only part of the outer surface of the adapter body 332, and this is not limited.

[0070] Since the adapter 330 needs to be fixedly connected with the first cover plate 310, and the adapter body 332 made of foam is difficult to be rigidly connected with the first cover plate 310, the first cover plate 310 is detachably connected with the fixing plate 333. Since the fixing plate 333 is arranged on the outer surface of the adapter body 332, the first cover plate 310 is detachably connected with the fixing plate 333, so that the adapter 330 can be mounted on the first cover plate 310.

[0071] In some embodiments, the fixing plate 333 includes a bottom plate 3331, a top plate 3332, and two side plates 3333. The two side plates 3333 are arranged on the two sides of the bottom plate 3331. The top plate 3332 connects the bottom plate 3331 and the two side plates 3333. The first cover plate 310 is in contact with the top plate 3332 and the two side plates 3333, and is detachably connected with the bottom plate 3331.

[0072] The fixed plate 333 is arranged in the adapter 330, the two side plates 3333 are arranged opposite to each other along the thickness direction, the bottom plate 3331 is arranged opposite to the first cover plate 310 along the width direction, and the top plate 3332 is arranged on the upper part of the side plate 3333 and the bottom plate 3331. The bottom plate 3331, the top plate 3332 and the two side plates 3333 form a groove structure, and the adapter body 332 is installed in the groove structure, and the adapter body 332 can be further protected. Since the bottom plate 3331 is arranged opposite to the first cover plate 310, the bottom plate 3331 and the first cover plate 310 are more convenient to connect, and the bottom plate 3331 and the first cover plate 310 can jointly clamp the adapter body 332, so that the adapter body 332 is fixed and installed.

[0073] In some embodiments, the adapter air duct 300 further comprises a fastener 340, the first cover plate 310 is provided with a second connecting hole 3334, the bottom plate 3331 is provided with a second connecting hole 3334, and the fastener 340 is arranged in the first connecting hole 311 and the second connecting hole 3334.

[0074] The fastener 340 is arranged in the first connecting hole 311 and the second connecting hole 3334, so that the first cover plate 310 and the fixed plate 333 are connected. Specifically, the fastener 340 can be a bolt, the first connecting hole 311 and the second connecting hole 3334 can be screw holes, and the fastener 340 is screwed into the first connecting hole 311 and the second connecting hole 3334, so that the first cover plate 310 and the bottom plate 3331 can be detachably connected.

[0075] Of course, since the fastener 340 needs to be arranged in the first cover plate 310 and the bottom plate 3331, the fastener 340 needs to be arranged in a staggered manner with the adapter body 332 to avoid damaging the structure of the adapter body 332 and thus damaging the transition passage 400.

[0076] In some embodiments, the bottom plate 3331 is provided with a mounting groove 3335, and the second connecting hole 3334 is arranged on the bottom surface 335 of the mounting groove 3335.

[0077] Since the adapter 330 is arranged in the fixed cavity 321, the fastener 340 can extend from the second connecting hole 3334 to the first connecting hole 311, so that the head of the fastener 340 is located in the fixed cavity 321 to ensure the appearance of the adapter air duct 300. Since the width of the fixed cavity 321 is limited, the head of the fastener 340 will occupy a certain space, so the mounting groove 3335 is arranged on the bottom plate 3331, the mounting groove 3335 is recessed inward, and the second connecting hole 3334 is arranged on the bottom surface 335 of the mounting groove 3335, so that the head of the fastener 340 is at least partially located in the mounting groove 3335 to reduce the space occupied by the head of the fastener 340 outside the fixed plate 333 as much as possible.

[0078] In some embodiments, the top plate 3332 is provided with a communication port 3336 for communicating the transition passage 400 and the air outlet duct 220.

[0079] The top of the adapter body 332 is used to be connected with the air outlet duct 220 to communicate the transition passage 400 and the air outlet duct 220. Since the top plate 3332 is arranged on the top of the adapter body, the top plate 3332 needs to be provided with the communication port 3336 for communicating the transition passage 400 and the air outlet duct 220, that is, the cold air in the transition passage 400 can enter the air outlet duct 220 through the communication port 3336.

[0080] In some embodiments, the first cover plate 310 is provided with a positioning boss 312, and the adapter body 332 is provided with a positioning groove 334, and the positioning boss 312 is arranged in the positioning groove 334.

[0081] The positioning boss 312 is located on the side of the first cover plate 310 close to the adapter body 332 and protrudes towards the adapter body 332, and the positioning groove 334 is located on the side of the adapter body 332 close to the first cover plate 310 and is recessed towards the bottom plate 3331. The positioning boss 312 is arranged in the positioning groove 334, so that the installation of the adapter 330 on the first cover plate 310 can be positioned, and the installation of the adapter 330 on the first cover plate 310 is more stable.

[0082] Please refer to Figure 11 In some embodiments, the adapter duct 300 further comprises a deodorization module 500, and the adapter 330 further has a deodorization installation cavity 337 for communicating with the deodorization duct 160 and an air return port 222 for communicating with the air return duct 150, and the deodorization module 500 is installed in the deodorization installation cavity 337, wherein the deodorization installation cavity 337 communicates with the air return port 222.

[0083] If the refrigeration equipment 10 stores food with heavy smell, such as dried pickles, hot pot materials, etc., the smell of these foods will be transmitted to other items, which will bring bad user experience. Therefore, a deodorization module 500 needs to be arranged for deodorization. Since the deodorization module 500 is installed in the deodorization installation cavity 337 of the adapter 330, that is, the adapter duct 300 of the present application not only can be used to connect the air outlet duct 220 and the air supply duct 110, but also integrates the function of installing the deodorization module 500. Therefore, when the adapter duct 300 is applied to the refrigeration equipment 10, there is no need to arrange the structure for installing the deodorization module 500 in the refrigeration equipment 10, thereby simplifying the structure of the refrigeration equipment 10.

[0084] The clean air duct 160 is arranged in the shell 210, and the return air duct 150 is arranged in the refrigeration equipment 10. The gas in the containing cavity can enter the return air duct 150 through the return air port 222 and enter the supply air duct 110 for refrigeration. The cold air enters the supply air duct 110 through the transition passage 400 to blow air to the containing cavity, so as to realize the circulation of the gas. Since the clean air installation cavity 337 is communicated with the return air port 222, the gas in the containing cavity can also enter the clean air module 500 through the return air port 222. After being purified by the clean air module 500, the clean gas is blown out through the clean air duct 160. That is, the clean air and the return air share one return air port 222, so that the structure can be further simplified.

[0085] Based on the same inventive concept, please refer to Figures 3-5 The embodiment of the present application provides a wind duct module 200, which comprises a shell 210 and the above-mentioned adapter duct 300. The air outlet duct 220 is arranged in the shell 210, and the adapter duct 300 is detachably mounted in the shell 210. The beneficial effects of the wind duct module 200 provided by the embodiment of the present application are the same as those of the above-mentioned adapter duct 300, and will not be repeated here.

[0086] The adapter duct 300 is detachably mounted in the shell 210. Therefore, when the adapter duct 300 is mounted, the position of the adapter duct 300 is first adjusted so that the transition passage 400 is aligned with the air outlet duct 220 and the supply air duct 110 respectively, the air outlet duct 220 and the supply air duct 110 are communicated, and then the adapter duct 300 and the shell 210 are connected, and the installation of the adapter duct 300 is completed. Of course, when the adapter duct 300 is displaced, resulting in a lower alignment degree of the air outlet duct 220 and the supply air duct 110, the adapter duct 300 is detached and the position is adjusted again, so that the convenience of the communication of the air outlet duct 220 and the supply air duct 110 is improved.

[0087] In some embodiments, the shell 210 has an inspection window 230, and the adapter duct 300 is mounted in the inspection window 230. The cover plate 300a is detachably connected with the shell 210.

[0088] Since the adapter duct 300 is mounted in the inspection window 230 of the shell 210, the adapter duct 300 does not occupy additional space, thereby reducing the overall size of the wind duct module 200. In addition, since the transition passage 400 and the air outlet duct 220 are both arranged in the shell 210, the transition passage 400 and the air outlet duct 220 are more convenient to connect and communicate.

[0089] It should be noted that since the transition passage 400 and the air outlet duct 220 are both arranged in the shell 210, the transition passage 400 is in communication with the air outlet duct 220, thus, when the adapter duct 300 is detached from the maintenance window 230, the air outlet duct 220 will be exposed to the maintenance window 230. Therefore, when the air outlet duct 220 needs to be maintained, the adapter duct 300 can be detached from the maintenance window 230, and the maintenance personnel can directly view and maintain the air outlet duct 220 through the maintenance window 230, without the need to disassemble the entire duct module 200, thereby greatly saving the maintenance time and improving the maintenance efficiency.

[0090] Please refer to Figure 8 and Figure 10 In some embodiments, the shell 210 is provided with a first fixing hole 211, the cover plate 300a is provided with a second fixing hole 360, and the fixing member 370 is arranged in the first fixing hole 211 and the second fixing hole 360.

[0091] The fixing member 370 is arranged in the first fixing hole 211 and the second fixing hole 360, that is, the maintenance member is connected to the duct module 200. Of course, the fixing member 370 is detachably mounted in the first fixing hole 211 and the second fixing hole 360, and when the maintenance member and the duct module 200 need to be separated, the fixing member 370 can be removed from the first fixing hole 211 and the second fixing hole 360.

[0092] Specifically, the fixing member 370 can be a bolt, the first fixing hole 211 and the second fixing hole 360 can be screw holes, and the fixing member 370 is screwed into the first fixing hole 211 and the second fixing hole 360, that is, the maintenance member is connected to the duct module 200.

[0093] Based on the same inventive concept, the embodiments of the present application also provide a refrigeration equipment 10, comprising a cabinet 100 and the above-mentioned duct module 200, the cabinet 100 has a cavity 140 for accommodating articles, and the duct module 200 is mounted on the cabinet 100, and the air outlet duct 220 is used to send air into the cavity 140.

[0094] Specifically, in the chamber 140 of the refrigeration device 10, including the freezing cavity 142 and the refrigerating cavity 141, the air supply air duct 110 can be used to supply air for the freezing cavity 142, and the air outlet air duct 220 can be used to supply air for the refrigerating cavity 141. The cabinet 100 can have a partition plate, which is used to divide the refrigerating cavity 141 and the freezing cavity 142 into two or more independent compartments, so as to better classify and store different kinds of food, such as vegetables, fruits, dairy products, etc., thereby facilitating management and maintaining the optimal freshness of the food. The refrigerating cavity 141 and the freezing cavity 142 both have a partition plate, and the air supply air duct 110 and the air outlet air duct 220 can be arranged in the partition plate, that is, the partition plate in the refrigerating cavity 141 is configured as the shell 210 of the air duct module 200. By carrying and accommodating the air supply air duct 110 and the air outlet air duct 220 through the partition plate, the space inside the partition plate can be effectively utilized, and the occupation of the air duct to the external space is reduced, so that the overall structure is more compact.

[0095] In some embodiments, the refrigeration device 10 further comprises a door body 700, which is arranged at the opening of the chamber 140, the thickness of the door body 700 is 25mm-40mm, and the total thickness of the cabinet 100 and the door body 700 is 450mm-600mm.

[0096] Since the thickness of the door body 700 is limited to 25mm-40mm, that is, the thickness of the door body 700 is relatively thin, thereby facilitating the user to open and close the door, and since the total thickness of the cabinet 100 and the door body 700 is limited to 450mm-600mm, that is, the thickness of the refrigeration device as a whole is relatively thin, thereby reducing the occupation area of the refrigeration device and facilitating transportation.

[0097] Specifically, the thickness of the door body 700 can be 26mm, 30mm, 32mm, 36mm, or 38mm, and the total thickness of the cabinet 100 and the door body 700 can be 480mm, 520mm, 540mm, 560mm, or 580mm.
