[0037] 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, or only one air duct module can be provided with refrigeration components, and the air duct is connected in communication with other air ducts to realize a set of refrigeration components for multiple 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.

[0038] In order to solve the problems in the related art to some extent, the application embodiment provides an air duct module and a refrigeration equipment. In the process of connecting, the position of the air supply duct or the air outlet duct does not need to be moved, only the position of the switching air duct is adjusted, so that the air supply duct and the air outlet duct are accurately connected, thereby greatly improving the convenience of connecting the air supply duct and the air outlet duct.

[0039] The application will be described below in conjunction with the drawings and specific embodiments:

[0040] Please refer to Figure 1 and Figure 2 The application embodiment provides an air duct module 200 installed in the box 100 of the refrigeration equipment 10. The air duct module 200 provided by the application embodiment can accurately connect the air supply duct 110 and the air outlet duct 220 in the process of connecting, without moving the position of the air supply duct 110 or the air outlet duct 220, only adjusting the position of the switching air duct 240, thereby greatly improving the convenience of connecting the air supply duct 110 and the air outlet duct 220.

[0041] The refrigeration equipment 10 can be a refrigerator or a refrigerator. In the application embodiment, in order to facilitate description, the refrigeration equipment 10 is taken as an example to illustrate the refrigerator, and when the refrigeration equipment 10 is other equipment, it can be analogized.

[0042] The refrigeration equipment 10 is generally cuboid, and for the convenience of description, a height direction Z, a width direction X and a thickness direction Y are defined, 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.

[0043] Similarly, for the convenience of description, six directions of up, down, left, right, front and back are defined. Among them, in the height direction Z, the direction close to the top surface 320 is up, and the direction away from the top surface 320 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, the direction close to the door body 700 is front, and the direction away from the door body 700 is back.

[0044] Please refer to Figures 3-5 In the embodiment of the present application, the air duct module 200 comprises a shell 210 and an adapter air duct 240. The shell 210 has an air outlet air duct 220; the adapter air duct 240 comprises an adapter 300 and a cover plate 400, the adapter 300 is installed on the cover plate 400, the adapter 300 has a transition passage 350 for communicating the air outlet air duct 220 and the air supply air duct 110, and the cover plate 400 is detachably connected with the shell 210.

[0045] Please refer to Figure 6 Among them, the cover plate 400 comprises a cover plate body 410 and a buckle 420 arranged on the cover plate body 410, the adapter 300 has a buckle groove 310, and the buckle 420 is clamped in the buckle groove 310, so that the adapter 300 is fixed on the cover plate body 410.

[0046] The shell 210 is the main structure of the entire air duct module 200, which can provide a mounting basis for the air outlet air duct 220. The air outlet air duct 220 is used for air supply to one of the chambers 140 of the refrigeration equipment 10. The air supply air duct 110 is arranged in the cabinet 100 of the refrigeration equipment 10 to supply air to other chambers 140 of the refrigeration equipment 10. The air supply air duct 110 is provided with an evaporator 120 and a flow guide 130. The evaporator 120 is used for refrigeration of air, and the flow guide 130 is used for circulation of cold air in the chamber 140. In the case that the air supply air duct 110 communicates with the air outlet air duct 220, the refrigerated gas in the air supply air duct 110 can enter the air outlet air duct 220 to supply air to the chamber 140. Specifically, the shell 210 has an air outlet 221 and an air return 222 which communicate with the air outlet air duct 220. The flow guide 130 can make the gas in the chamber 140 enter the air supply air duct 110 through the air return 222, and the gas in the air outlet air duct 220 flow to the chamber 140 from the air outlet 221.

[0047] The adapter air duct 240 comprises an adapter 300 and a cover plate 400, the adapter 300 has a transition passage 350 for connecting the air outlet duct 220 and the air supply duct 110, and the cover plate 400 is detachably connected with the shell 210, so that when the air outlet duct 220 and the air supply duct 110 are connected, the air supply duct 110 and the air outlet duct 220 can be connected through the transition passage 350 respectively, so as to realize the connection of the air supply duct 110 and the air outlet duct 220. That is, during the connection process, the position of the entire air duct module 200 does not need to be moved, only the position of the adapter air duct 240 needs to be adjusted, so that the air supply duct 110 and the air outlet duct 220 can be connected accurately, and after the connection is completed, the cover plate 400 is connected with the shell 210, so as to greatly improve the convenience of the connection of the air supply duct 110 and the air outlet duct 220.

[0048] In addition, since the cover plate 400 is detachably connected with the shell 210, when the alignment degree between the air outlet duct 220 and the air supply duct 110 is poor, the cover plate 400 is separated from the shell 210, and the position of the adapter air duct 240 is adjusted again, so that the air supply duct 110 and the air outlet duct 220 can be connected accurately, and the air duct module 200 and the surrounding parts do not need to be disassembled, so that the adjustment time is greatly reduced.

[0049] It should be noted that since the transition passage 350 is connected with the air outlet duct 220 and the air supply duct 110, the cold air of the air supply duct 110 will pass through the transition passage 350, in order to reduce the loss of cold energy when the cold air passes through the transition passage 350, the adapter 300 needs to be made of a heat-insulating material such as foam, and since the foam is difficult to be rigidly connected with the shell 210, the cover plate 400 needs to be detachably connected with the shell 210.

[0050] The cover plate 400 comprises a cover plate body 410 and a buckle 420 arranged on the cover plate body 410, the cover plate body 410 is detachably connected with the shell 210, the adapter 300 has a buckle groove 310, and the buckle 420 is buckled in the buckle groove 310, so that the adapter 300 is fixed on the cover plate body 410. That is, the cover plate 400 and the adapter 300 are detachably connected through buckling, when the adapter air duct 240 is installed, the adapter 300 and the cover plate 400 can be assembled together first, then the position of the adapter air duct 240 is adjusted to make the transition passage 350 connect the air supply duct 110 and the air outlet duct 220 respectively, and finally the cover plate body 410 is connected with the shell 210, so as to complete the installation of the adapter air duct 240.

[0051] Please refer to Figures 7-9In some embodiments, the adapter 300 has a top surface 320, a bottom surface 330, and a connecting surface 340, the top surface 320 and the bottom surface 330 are oppositely arranged, the top surface 320 is in contact with the air outlet duct 220, the bottom surface 330 is used to be in contact with the air supply duct 110, the connecting surface 340 connects the top surface 320 and the bottom surface 330, and the buckle groove 310 is arranged on the connecting surface 340.

[0052] The air outlet duct 220 is located above the air supply duct 110, the top surface 320 is in contact with the air outlet duct 220, so that the transition passage 350 is in communication with the air outlet duct 220, and the bottom surface 330 is in contact with the air supply duct 110, so that the transition passage 350 is in communication with the air supply duct 110. Since the top surface 320 and the bottom surface 330 need to be in contact with the air outlet duct 220 and the air supply duct 110 respectively, in order to make the buckle 420 not interfere with the contact of the top surface 320 and the bottom surface 330 with the air outlet duct 220 and the air supply duct 110, the buckle groove 310 is arranged on the connecting surface 340.

[0053] In some embodiments, the connecting surface 340 includes a side surface 341 arranged at an angle and an end surface 342, the cover plate body 410 is in contact with the side surface 341, and the buckle groove 310 is arranged on the end surface 342.

[0054] Among them, the side surface 341 is arranged along the width direction, and the end surface 342 is arranged along the thickness direction, since the cover plate body 410 is in contact with the side surface 341, the buckle 420 can only cooperate with the end surface 342, and therefore the buckle groove 310 is arranged on the end surface 342.

[0055] In some embodiments, the end surface 342 has two, both of the two end surfaces 342 are provided with the buckle groove 310, and at least one of the end surfaces 342 is provided with two buckle grooves 310, one of which is arranged close to the bottom surface 330, and the other is arranged close to the top surface 320.

[0056] The end surface 342 and the side surface 341 both have two, the two end surfaces 342 are oppositely arranged along the thickness direction, and the two side surfaces 341 are oppositely arranged along the width direction, and the cover plate body 410 is in contact with one of the side surfaces 341. Both of the two end surfaces 342 are provided with the buckle groove 310, that is, the adapter 300 is connected with the cover plate body 410 on both sides in the thickness direction, so that the relative position between the cover plate 400 and the adapter 300 in the thickness direction can be limited, and the installation of the adapter 300 on the cover plate 400 is more stable.

[0057] At least one of the end faces 342 is provided with two buckle grooves 310, that is, one of the end faces 342 is provided with two buckle grooves 310, or both of the end faces 342 are provided with two buckle grooves 310, which is not limited. Since one of the two buckle grooves 310 on one of the end faces 342 is arranged close to the bottom face 330, and the other buckle groove 310 is arranged close to the top face 320, the connecting force between the cover plate body 410 and the adapter 300 in the height direction is balanced, so that the connecting force between the cover plate body 410 and the adapter 300 is more stable.

[0058] Of course, the buckle grooves 310 and the buckle pieces 420 are arranged one by one, and each buckle groove 310 is clamped with the corresponding buckle piece 420.

[0059] In some embodiments, the buckle piece 420 includes a connecting portion 421 and a buckle portion 422, the connecting portion 421 is connected with the cover plate 400, and the buckle portion 422 is arranged in the buckle groove 310, the buckle groove 310 has a stop face 311 arranged opposite to the side face 341, and the buckle portion 422 has a clamping face 4221 abutting against the stop face 311.

[0060] Since the side face 341 is arranged along the width direction, that is, the stop face 311 is arranged opposite to the side face 341 in the width direction, since the cover plate body 410 is in contact with the side face 341, and the clamping face 4221 abuts against the stop face 311, that is, the cover plate body 410 and the clamping face 4221 jointly limit the adapter 300 in the width direction, in other words, the cooperation of the cover plate body 410 and the side face 341, and the cooperation of the clamping face 4221 and the stop face 311 limit the relative position between the cover plate 400 and the adapter 300 in the width direction, so that the installation of the adapter 300 on the cover plate 400 is more stable.

[0061] In some embodiments, the buckle groove 310 has a limiting face 312 and / or a supporting face 313 arranged at an angle with the stop face 311, the limiting face 312 is arranged above the buckle portion 422 and abuts against the buckle portion 422, and the supporting face 313 is arranged below the buckle portion 422 and abuts against the buckle portion 422.

[0062] Please refer to Figure 9 and Figure 10 The buckle groove 310 has a plurality of limiting faces 312 and / or supporting faces 313 arranged at an angle with the stop face 311, that is, some of the buckle grooves 310 have the limiting face 312, some of the buckle grooves 310 have the supporting face 313, or all of the buckle grooves 310 have the limiting face 312 and the supporting face 313 at the same time, which is not limited.

[0063] Since the limiting surface 312 is arranged above the buckle portion 422 and abuts against the buckle portion 422, and the supporting surface 313 is arranged below the buckle portion 422 and abuts against the buckle portion 422, that is, the limiting surface 312 and the supporting surface 313 jointly limit the height direction of the buckle 420, thereby limiting the relative position between the cover plate 400 and the adapter 300 in the height direction, so that the installation of the adapter 300 on the cover plate 400 is more stable.

[0064] In some embodiments, the buckle portion 422 further has an abutting surface 4222 formed by the stop surface 311 arranged at an angle, and the abutting surface 4222 abuts against the bottom surface 330 of the buckle groove 310.

[0065] The abutting surface 4222 abuts against the bottom surface 330 of the buckle groove 310, which can increase the contact area between the buckle portion 422 and the buckle groove 310, increase the friction between the buckle portion 422 and the buckle groove 310, thereby making the buckle portion 422 and the buckle groove 310 more stable, and making the installation of the adapter 300 on the cover plate 400 more stable.

[0066] Please refer to Figure 4 In some embodiments, the adapter air duct 240 further comprises a mounting member 241, the mounting member 241 is arranged on the side of the adapter 300 away from the cover plate 400, and the mounting member 241 is integrally formed with the shell 210.

[0067] The cover plate 400 is arranged on only one side of the adapter 300, and since the mounting member 241 is made of foam and has a relatively fragile structure, when the air duct module 200 is applied in the refrigeration equipment 10, if the other side of the adapter 300 is exposed outside the air duct module 200, it is easy to be damaged. Therefore, the adapter air duct 240 further comprises a mounting member 241, the mounting member 241 is arranged on the side of the adapter 300 away from the cover plate 400, so as to protect the side of the adapter 300 away from the cover plate 400. The mounting member 241 is integrally formed with the shell 210, thereby reducing the assembly steps of the air duct module 200 and improving the production efficiency.

[0068] In some embodiments, the shell 210 has an inspection window 230, and the adapter air duct 240 is arranged in the inspection window 230.

[0069] Since the adapter air duct 240 is arranged in the inspection window 230 of the shell 210, the adapter air duct 240 does not occupy additional space, thereby reducing the overall size of the air duct module 200, and since the transition passage 350 and the air outlet duct 220 are both arranged in the shell 210, it is more convenient for the transition passage 350 and the air outlet duct 220 to be connected and communicated.

[0070] It should be noted that since the transition passage 350 and the air outlet air duct 220 are both arranged in the shell 210, the transition passage 350 is in communication with the air outlet air duct 220, and thus when the adapter air duct 240 is detached from the maintenance window 230, the air outlet air duct 220 is exposed to the maintenance window 230. Therefore, when the air outlet air duct 220 needs to be maintained, the adapter air duct 240 can be detached from the maintenance window 230, and the maintenance personnel can directly view and maintain the air outlet air duct 220 through the maintenance window 230 without the need to disassemble the entire air duct module 200, thereby greatly saving the maintenance time and improving the maintenance efficiency.

[0071] Based on the same inventive concept, please refer to Figure 1 and Figure 2 The embodiments of the present application also provide a refrigeration equipment 10, which comprises a cabinet 100 and the air duct module 200 described above, the cabinet 100 has a chamber 140 for containing articles, and the air duct module 200 is installed in the cabinet 100, and the air outlet air duct 220 is used to supply air to the chamber 140.

[0072] Specifically, the chamber 140 of the refrigeration equipment 10 comprises a freezing chamber 142 and a refrigerating chamber 141, the air supply air duct 110 can be used to supply air to the freezing chamber 142, and the air outlet air duct 220 can be used to supply air to the refrigerating chamber 141. The cabinet 100 can have a partition plate, which is used to divide the refrigerating chamber 141 and the freezing chamber 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 the management and maintaining the optimal preservation state of the food. The refrigerating chamber 141 and the freezing chamber 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, i.e. the partition plate in the refrigerating chamber 141 is configured as the shell 210 of the air duct module 200. By carrying and containing 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 external space by the air duct is reduced, so that the overall structure is more compact.

[0073] In some embodiments, the refrigeration equipment 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.

[0074] Since the thickness of the door body 700 is limited to 25mm-40mm, i.e. the thickness of the door body 700 is relatively thin, it is convenient for 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, i.e. the thickness of the refrigeration equipment as a whole is relatively thin, the occupation area of the refrigeration equipment can be reduced, and the transportation is facilitated.

[0075] Specifically, the thickness of the door body 700 can be 26mm, 30mm, 32mm, 36mm, 38mm, and the total thickness of the box body 100 and the door body 700 can be 480mm, 520mm, 540mm, 560mm, 580mm.
