[0044] The refrigeration equipment is a professional storage tool for storing various frozen goods, which can keep food or other goods in frozen state. The refrigeration system of the refrigeration equipment is composed of compressor, condenser, capillary, evaporator and other parts, which can bring the heat inside the freezer to the outside of the freezer through the continuous circulation of refrigerant, so as to achieve the purpose of cooling.

[0045] In the related art, the refrigeration equipment has multiple chambers, and different chambers can be configured to different temperatures to meet different storage requirements; the inner tank of the refrigeration equipment can be divided into different chambers by arranging the air duct structure in the inner tank. Since the air supply port on the air duct structure is usually arranged on the side wall of the air duct structure, the heat insulation effect of the chamber is affected, which is not conducive to the independent temperature adjustment of each chamber.

[0046] The present application will be described below in conjunction with the drawings and specific embodiments:

[0047] Please refer to Figure 1 and Figure 3 The air duct structure provided by the embodiments of the present application is mainly applied to the refrigeration equipment 10, and the air duct structure 100 provided by the embodiments of the present application is used to supply air to the refrigeration equipment 10. The refrigeration equipment 10 is internally provided with multiple chambers, such as a first chamber 210 and a second chamber 220. The air duct structure 100 provided by the embodiments of the present application enables cold air to flow in the first chamber 210 and the second chamber 220 in the refrigeration equipment 10, so as to achieve the freezing effect.

[0048] The refrigeration equipment 10 can be a refrigerator or a freezer. In the embodiments of the present application, the refrigeration equipment 10 is taken as an example for description, and the same applies to other refrigeration equipment.

[0049] The refrigeration equipment 10 is generally a cuboid. For the convenience of description, the height direction Z, the width direction X and the thickness direction Y are defined. 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.

[0050] For the convenience of description, the six directions of up, down, left, right, front and back are defined. In the height direction Z, the two directions are up and down. In the width direction X, the two directions are left and right. In the thickness direction Y, the connection between the door body 500 and the cabinet is the front, and the opposite side is the back.

[0051] In the embodiments of the present application, the air duct structure 100 includes a shell 120 and a fan assembly 130. The shell 120 has a mounting cavity 121, and the mounting cavity 121 has a mounting top wall 121a. The mounting top wall 121a has a first air supply port 122 for supplying air to the first chamber 210. The fan assembly 130 is arranged in the mounting cavity 121 and can make the air in the mounting cavity 121 blow to the first chamber 210 through the first air supply port 122.

[0052] The air duct structure 100 is applied to the refrigeration equipment 10 and is installed in the cabinet of the refrigeration equipment 10. The air duct structure 100 can make the air in the refrigeration equipment 10 flow, so that the air in the refrigeration equipment 10 can be blown to the frozen items after being cooled by the evaporator. That is, the air duct structure 100 is mainly used to blow cold air into the refrigeration equipment 10, so that the cold air can circulate in the refrigeration equipment 10, and the temperature in the same chamber of the refrigeration equipment 10 is substantially the same, and the temperature difference in the same chamber is reduced.

[0053] Since the thickness of the air duct structure 100 is smaller than the width, the width of the air duct structure 100 is substantially equal to the thickness of the refrigeration equipment 10. The air duct structure 100 can be installed on one side of the refrigeration equipment 10 in the width direction X, so that the air blown out of the refrigeration equipment 10 can cover the side formed by the length direction and the width direction X as much as possible. The air blown out of the shell 120 can cover the entire inside of the shell 120, and the uniformity of freezing is improved as much as possible.

[0054] Of course, the air duct structure 100 can be arranged between the first chamber 210 and the second chamber 220 to isolate the first chamber 210 and the second chamber 220, and facilitate the air duct structure 100 to supply air to the first chamber 210 and the second chamber 220.

[0055] The shell 120 is a basic component of the air duct structure 100, which can provide a mounting base for other structures of the air duct structure 100. The fan assembly 130 and other structures can be mounted on the shell 120, so that the air duct structure 100 can form an integral whole, which can facilitate the installation and transportation of the air duct structure 100. At the same time, the shell 120 can also protect the fan assembly 130 and other structures, which can reduce the damage of external structures to the fan assembly 130 and other structures.

[0056] In the embodiments of the present application, the height direction Z, the width direction X and the thickness direction Y of the shell 120 are defined for convenience of description.

[0057] The fan assembly 130 is used to drive the air flow, so that the air in the mounting cavity 121 is blown to the first chamber 210 through the first air outlet 122 and to the second chamber 220 through the second air outlet 123.

[0058] The first air outlet 122 is located on the top wall of the mounting cavity 121, and the cold air flows out of the mounting cavity 121 through the first air outlet 122 and then blows to the first chamber 210, avoiding the direct communication between the mounting cavity 121 and the first chamber 210, and reducing the influence of the temperature of the mounting cavity 121 on the first chamber 210; the first air outlet 122 on the mounting top wall 121a is used to send air to the first chamber 210, so as to avoid the opening between the first chamber 210 and the mounting cavity 121, improve the heat insulation effect of the first chamber 210, and be conducive to maintaining the temperature of the first chamber 210.

[0059] In some embodiments, the mounting cavity 121 has a mounting side wall 121b, and the mounting side wall 121b has a second air outlet 123 for sending air to the second chamber 220, and the cold air is blown to the second chamber 220 through the second air outlet 123.

[0060] The second air outlet 123 is located on the side wall of the mounting cavity 121, and the second air outlet 123 can directly send the cold air to the second chamber 220 through the second air outlet 123 on the mounting side wall 121b, reducing the path of the cold air flow and increasing the air outlet efficiency; the first air outlet 122 is located on the top wall of the mounting cavity 121, and the second air outlet 123 is located on the side wall of the mounting cavity 121, so that the cold air in the mounting cavity 121 flows in different directions, reducing the possibility of air flow between the first chamber 210 and the second chamber 220, and isolating the first chamber 210 and the second chamber 220 as much as possible, reducing the heat transfer between the first chamber 210 and the second chamber 220, and being conducive to maintaining the temperature difference between the first chamber 210 and the second chamber 220.

[0061] The air duct structure 100 can deliver cold air to the first chamber 210 and the second chamber 220 to reduce the temperature of the first chamber 210 and the second chamber 220, the temperature of the second chamber 220 is lower than the temperature of the first chamber 210, the second chamber 220 reaches a set temperature, the air duct structure 100 stops delivering air to the second chamber 220, and continues to deliver air to the first chamber 210; the air duct structure 100 can be arranged between the first chamber 210 and the second chamber 220 to isolate the first chamber 210 and the second chamber 220, since the first air outlet 122 is located on the top wall of the mounting cavity 121 and the second air outlet 123 is located on the side wall of the mounting cavity 121, in the case that the air duct structure 100 stops delivering air to the second chamber 220, heat transfer between the air duct structure 100 and the second chamber 220 can be reduced, so that the second chamber 220 is maintained within a set temperature range. Of course, the air duct structure 100 can also deliver hot air to the first chamber 210 and the second chamber 220, which is not particularly limited in the embodiments of the present application.

[0062] The air duct structure 100 can be installed in the refrigeration device 10, the first chamber 210 can be a freezer compartment of the refrigeration device 10, and the second chamber 220 can be a variable temperature compartment of the refrigeration device 10; the temperature of the variable temperature compartment can be adjusted and suitable for storing different types of storage requirements, and the variable temperature range of the variable temperature compartment is -3-5℃. The temperature of the general freezer compartment is lower than that of the variable temperature compartment. The air duct structure 100 is arranged between the freezer compartment and the variable temperature compartment to isolate the freezer compartment and the variable temperature compartment.

[0063] Wherein, the mounting top wall 121a refers to the upper wall of the shell 120; that is, in the normal use state of the refrigeration device 10, the mounting top wall 121a is located on the upper side of the shell 120. The mounting side wall 121b refers to the left wall or the right wall of the shell 120; that is, in the normal use state of the refrigeration device 10, the mounting top wall 121a is located on the left side or the right side of the shell 120. The mounting side wall 121b can be arranged on the side of the shell 120 facing the first chamber 210, or on the side of the shell 120 facing the second chamber 220.

[0064] Please refer to Figure 1 and Figure 3 In some embodiments, the air duct structure 100 further comprises a first air outlet component 140, which is in communication with the first air outlet 122 and the first chamber 210 and is used for delivering air to the first chamber 210.

[0065] The first air outlet component 140 can be used to supply air to the first chamber 210, and the air supply port of the installation cavity 121 does not need to be opened towards the side wall of the second chamber 220. In the case that the air duct structure 100 stops supplying air to the second chamber 220, the influence of the air duct structure 100 on the second chamber 220 can be reduced, and the temperature of the second chamber 220 can be maintained. The first air outlet component 140 supplies air to the first chamber 210, so that the air inlet path of the first chamber 210 is single-controllable, and the temperature of the first chamber 210 can be controlled conveniently.

[0066] The first air outlet component 140 is located outside the installation cavity 121, so as to avoid occupying the space of the installation cavity 121. The first air outlet component 140 can reduce the direct connection between the second chamber 220 and the air duct structure 100, and improve the heat insulation effect of the second chamber 220 without supplying air to the second chamber 220.

[0067] Please refer to Figure 4 In some embodiments, the first air outlet component 140 has a ventilation cavity 141, a first air outlet 143a and a second air outlet 143b. The first air outlet 143a is located at the top of the first chamber 210, and the second air outlet 143b is located at the rear of the first chamber 210. The ventilation cavity 141 can enable the air blown out from the first air supply port 122 to enter the first chamber 210 through at least one of the first air outlet 143a and the second air outlet 143b.

[0068] The first air outlet 143a and the second air outlet 143b can be used to supply air to the first chamber 210, and the efficiency of supplying air to the first chamber 210 can be improved. The first air outlet 143a is located at the top of the first chamber 210, and the second air outlet 143b is located at the rear of the first chamber 210. The air can be supplied to the first chamber 210 from multiple directions, so that the air flow in the first chamber 210 is more uniform, the temperature difference between different positions in the first chamber 210 is reduced, and the problem of uneven refrigeration or freezing of food caused by the temperature difference is reduced.

[0069] The cabinet of the refrigeration device 10 has a taking and placing opening 230, which communicates the first chamber 210 and the second chamber 220. Through the taking and placing opening 230, the articles can be taken out from the first chamber 210 or the second chamber 220, or the articles to be stored can be placed in the first chamber 210 or the second chamber 220. The taking and placing opening 230 is located at the front of the cabinet, and the door body 500 of the refrigeration device 10 covers the taking and placing opening 230. When the user takes or places the articles through the taking and placing opening 230, cold air may overflow from the taking and placing opening 230. The second air outlet 143b is located at the rear of the first chamber 210, so that the possibility of cold air overflowing from the taking and placing opening 230 is reduced, and energy is saved. The rear of the first chamber 210 is the side of the first chamber 210 away from the taking and placing opening 230.

[0070] The air flow first passes through the ventilation cavity 141, and then enters the first chamber 210 through at least one of the first air outlet 143a and the second air outlet 143b, so as to reduce the temperature difference of the air flowing through the first air outlet 143a and the second air outlet 143b as much as possible, improve the uniformity of the cold air in the first chamber 210, and further improve the refrigeration effect.

[0071] The mounting side wall 121b of the mounting cavity 121 is provided with a first return air outlet 124 and a second return air outlet 125; the first return air outlet 124 is communicated with the first chamber 210, and the gas in the first chamber 210 enters the mounting cavity 121 through the first return air outlet 124; the second return air outlet 125 is communicated with the second chamber 220, and the gas in the second chamber 220 enters the mounting cavity 121 through the second return air outlet 125.

[0072] Please refer to Figure 1 In some embodiments, the height of the second air outlet 143b is lower than the height of the first air outlet 143a.

[0073] It can be understood that the first air outlet 143a and the second air outlet 143b are arranged in sequence from high to low, and the first air outlet 143a is closer to the top of the first chamber 210 than the second air outlet 143b, and the second air outlet 143b is arranged at the middle region of the first chamber 210, so as to make the cold air enter at different height positions in the first chamber 210, so that the cold air can be blown to different regions of the first chamber 210 more uniformly, and the refrigeration effect is better.

[0074] The first return air outlet 124 is close to the bottom of the first chamber 210, so that the cold air can form a plurality of different circulation regions, and the refrigeration effect is improved. Specifically, the user basically stacks from bottom to top during the process of placing articles, and the lower articles are more, and the cold quantity required is also more. The second air outlet 143b is arranged between the first air outlet 143a and the first return air outlet 124, so that the cold air can be blown out from the middle region of the cabinet, and can be blown to the bottom region of the first chamber 210 as soon as possible. Through the cooperation of the first air outlet 143a and the second air outlet 143b, the cold air can be blown to different regions in the first chamber 210 more uniformly, and the refrigeration effect is better.

[0075] Please refer to Figure 1 and Figure 4 In some embodiments, the length direction of at least one of the first air outlet 143a and the second air outlet 143b is arranged along the width direction of the first chamber 210.

[0076] The length direction of the first air outlet 143a is arranged along the width direction of the first chamber 210, so that the cold air of the first air outlet 143a is uniformly distributed in the width direction of the first chamber 210, improving the uniformity of the temperature inside the first chamber 210, thereby improving the freezing effect; the first air outlet 143a is located at the top of the first chamber 210, and the probability of the accumulation of articles to the top of the first chamber 210 is small, and the resistance of the cold air blown out by the first air outlet 143a is small, so that the flow of the cold air blown out by the first air outlet 143a is better; the length direction of the first air outlet 143a is arranged along the width direction of the first chamber 210, so that the cold air blown out by the first air outlet 143a flows more uniformly in the width direction of the first chamber 210, and the temperature difference between each position inside the first chamber 210 is reduced as much as possible, and the problem of uneven refrigeration or freezing of food caused by temperature difference is reduced.

[0077] The length direction of the second air outlet 143b is arranged along the width direction of the first chamber 210, so that the cold air of the second air outlet 143b is uniformly distributed in the width direction of the first chamber 210, improving the uniformity of the temperature inside the first chamber 210, thereby improving the freezing effect; the second air outlet 143b is located at the rear of the first chamber 210, so that the cold air blown out by the second air outlet 143b flows from the rear to the front of the first chamber 210; the length direction of the second air outlet 143b is arranged along the width direction of the first chamber 210, so that the cold air blown out by the first air outlet 143a flows more uniformly in the width direction of the first chamber 210, and the range of the cold air blown out by the first air outlet 143a in the width direction of the first chamber 210 is large, so that the temperature difference between each position inside the first chamber 210 is reduced as much as possible, and the problem of uneven refrigeration or freezing of food caused by temperature difference is reduced.

[0078] The length direction of the first air outlet 143a can be arranged along the width direction of the first chamber 210, or the length direction of the second air outlet 143b can be arranged along the width direction of the first chamber 210; in the embodiment of the present application, the length direction of the first air outlet 143a and the length direction of the second air outlet 143b are both arranged along the width direction of the first chamber 210, so as to make the cold air act on each area inside the first chamber 210 as much as possible.

[0079] In some embodiments, the fourth air outlet 143d is formed between the first air outlet component 140 and the rear wall of the first chamber 210, and faces the bottom of the first chamber 210, so that cold air can be blown to the bottom of the first chamber 210 to cool the food at the bottom of the first chamber 210; the fourth air outlet 143d can increase the flow direction of the cold air in the first chamber 210, so that the distribution of the cold air inside the first chamber 210 is more uniform, and the temperature difference between different parts of the first chamber 210 is reduced. The fourth air outlet 143d is located below the second air outlet 143b, so that the cold air can flow to different height positions in the first chamber 210, improving the freezing effect.

[0080] Referring to Figure 1 and Figure 4 In some embodiments, the first air outlet component 140 includes a body member 142 and a first air outlet member 143, the ventilation cavity 141 is at least partially formed in the body member 142, the first air outlet member 143 is arranged side by side with the shell 120, and the body member 142 communicates the first air outlet member 143 and the first air supply opening 122. The first air outlet member 143 is used to supply air to the first chamber 210.

[0081] The first air outlet member 143 is arranged side by side with the shell 120, and the first air outlet member 143 can guide the air flow from the first air supply opening 122 at the top of the mounting cavity 121 to the first chamber 210 through the body member 142, so as to supply air to the first chamber 210.

[0082] The first chamber 210 is formed on one side of the air duct structure 100, and the first air outlet member 143 is arranged side by side with the shell 120, so that the first air outlet member 143 can extend into the interior of the first chamber 210, which is conducive to accurately supplying air to the first chamber 210; the first air outlet 143a and the second air outlet 143b are arranged on the first air outlet member 143, and the specific positions of the first air outlet 143a and the second air outlet 143b can be arranged through the first air outlet member 143, so that the flow of air in the first chamber 210 is more uniform.

[0083] By supplying air to the first chamber 210 through the first air outlet member 143, multiple air outlets at different heights can be arranged on the first air outlet member 143, for example, multiple first air outlets 143a or second air outlets 143b are arranged on the first air outlet member 143, which can improve the air supply efficiency while reducing the number of openings on the inner wall of the first chamber 210, thereby improving the heat insulation effect of the first chamber 210 and being conducive to maintaining the temperature of the first chamber 210.

[0084] The ventilation cavity 141 is at least partially located in the body piece 142, so that the cold air in the mounting cavity 121 can pass through the body piece 142 to the first air outlet piece 143 arranged side by side with the shell 120, and the cold air in the mounting cavity 121 can be sent to the first cavity 210 without the need of opening a hole between the first cavity 210 and the mounting cavity 121. The ventilation cavity 141 can be entirely arranged in the body piece 142, or partially arranged in the body piece 142 and partially arranged in the first air outlet piece 143, as long as the body piece 142 can send the cold air in the mounting cavity 121 to the first air outlet piece 143.

[0085] Please refer to Figure 1 and Figure 4 In some embodiments, the first air outlet piece 143 includes a first air outlet section 144 and a second air outlet section 145 connected with each other, the first air outlet section 144 is connected with the body piece 142, the first air outlet section 144 is located at the top of the first cavity 210, the second air outlet section 145 is located at the rear of the first cavity 210, and the first air outlet piece 143 sends air to the first cavity 210 through at least one of the first air outlet section 144 and the second air outlet section 145.

[0086] The first air outlet piece 143 sends air to the first cavity 210 through at least one of the first air outlet section 144 and the second air outlet section 145, the first air outlet section 144 is located at the top of the first cavity 210, a first air outlet 143a can be arranged on the first air outlet section 144, the second air outlet section 145 is located at the rear of the first cavity 210, and a second air outlet 143b can be arranged on the second air outlet section 145, so that air is sent to the first cavity 210 from multiple directions, the airflow in the first cavity 210 is more uniform, the temperature difference between different positions in the first cavity 210 is reduced, and the problem of uneven refrigeration or freezing of food caused by temperature difference is reduced.

[0087] The first air outlet section 144 and the second air outlet section 145 are connected to form the first air outlet piece 143, so that the relative positional relationship between the first air outlet piece 143 and the second air outlet piece 152 does not need to be adjusted during installation, facilitating installation; after the cold air in the body piece 142 passes through the first air outlet section 144, part of the cold air is blown to the first cavity 210 through the first air outlet 143a, and the other part of the cold air flows to the second air outlet section 145 and is blown to the first cavity 210 through the second air outlet 143b. Part of the ventilation cavity 141 is located in the body piece 142, part of the ventilation cavity 141 is located in the first air outlet section 144, and part of the ventilation cavity 141 is located in the second air outlet section 145, so that the cold air passing through the ventilation cavity 141 can make the cold air blown out from the first air outlet 122 enter the first cavity 210 through at least one of the first air outlet 143a and the second air outlet 143b.

[0088] The first air outlet section 144 is located at the top of the first chamber 210, and the second air outlet section 145 is located at the rear of the first chamber 210. The first chamber 210 can be blown from different directions through only one first air outlet part 143, so that the number of components inside the first chamber 210 can be reduced, and the integration of the air duct structure 100 can be improved. The first chamber 210 only needs to open one hole to connect the first air outlet part 140, so that the number of holes in the inner wall of the first chamber 210 can be reduced, and the heat insulation effect of the first chamber 210 can be improved. In addition, the above arrangement can reduce the occupation of the first chamber 210 by the first air outlet part 143, so that the first chamber 210 can accommodate as many items as possible, and the capacity of the first chamber 210 can be improved.

[0089] Please refer to Figures 4 to 6 In some embodiments, one of the first air outlet part 143 and the body part 142 is provided with a clamping groove 142a, and the other is provided with a clamping protrusion 143c. The clamping protrusion 143c cooperates with the clamping groove 142a.

[0090] Through the cooperation of the clamping protrusion 143c and the clamping groove 142a, the first air outlet part 143 and the body part 142 are connected. The connection between the first air outlet part 143 and the body part 142 can be completed by simply aligning and pressing or buckling the two parts, which simplifies the installation process, makes the connection between the first air outlet part 143 and the body part 142 more simple and reliable, and improves the stability of the structure.

[0091] In some embodiments, the body part 142 is provided with a clamping groove 142a, and the first air outlet part 143 is provided with a clamping protrusion 143c. The body part 142 is provided with a barb 142c on the side facing the first air outlet part 143, and the clamping groove 142a is formed between the barb 142c and the body part 142. The body part 142 is provided with a spring piece 142d on the side of the barb 142c, and the spring piece 142d is provided with a clamping groove 142a.

[0092] Specifically, in the cooperation process, the spring piece 142d is bent to make the second buckle extend between the barb 142c and the spring piece 142d, so that the second buckle is buckled in the second groove. The spring piece 142d is released, and the spring piece 142d is restored, so that the first buckle is buckled in the first groove. A buckling block can be provided at the end of the spring piece 142d to facilitate manual bending of the spring piece 142d.

[0093] Please refer to Figure 1 and Figure 4In some embodiments, the body piece 142 is located outside the first chamber 210, and the mounting cavity 121 and the first chamber 210 can be connected through the body piece 142, avoiding opening a hole between the mounting cavity 121 and the first chamber 210, so that the first chamber 210 is independent of the mounting cavity 121, and the mounting cavity 121 and the first chamber 210 are not directly connected, and the influence of the mounting cavity 121 on the temperature of the first chamber 210 is minimized. By arranging the body piece 142 outside the first chamber 210, the space occupied by the body piece 142 in the first chamber 210 can be reduced, and the capacity of the first chamber 210 can be maximized to store more items.

[0094] Referring to Figure 2 and Figure 3 In some embodiments, the second air outlet 123 is a plurality of second air outlets 123, and at least two second air outlets 123 are arranged at intervals along the height direction Z of the shell 120, so that the cold air blown out by the second air outlet 123 can blow to different height positions of the second chamber 220, so that the cold air flows in different heights of the second chamber 220, and covers as much area as possible at different heights of the second chamber 220, thereby improving the uniformity of the cold air in the second chamber 220, thereby improving the freezing effect. By arranging a plurality of second air outlets 123, the efficiency of cold air delivery can be improved, thereby improving the freezing effect.

[0095] Referring to Figure 1 and Figure 3 In some embodiments, the air duct structure 100 further comprises a second air outlet component 150, and the second air outlet component 150 has a third air outlet 152a, and the third air outlet 152a is in communication with the second air outlet 123 and is arranged at intervals along the width direction X of the shell 120.

[0096] The second air outlet component 150 sends the air through the second air outlet 123 to the second chamber 220 through the third air outlet 152a, so that the cold air can blow to each area of the second chamber 220 as much as possible; since the second air outlet 123 is located on the side wall of the shell 120, and the air duct structure 100 is located on one side wall of the second chamber 220, so that the opposite side wall is farthest from the air duct structure 100, and thus the frozen items near the opposite side wall receive the least cold air; along the width direction X of the shell 120, the third air outlet 152a is arranged at intervals with the shell 120, and the cold air is blown through the third air outlet 152a to the side of the shell 120 farthest from the air duct structure 100, so that the cold air flows to the farthest position as much as possible, and thus the frozen items farthest from the air duct structure 100 are frozen.

[0097] Referring to Figure 1 and Figure 3In some embodiments, the third air outlet 152a is located at the top of the shell 120. Since there is less possibility of placing articles at the top of the second chamber 220, the cold air is less resistant, so that the flow of cold air at the top of the second chamber 220 is large, and in turn, the cold air blown from the third air outlet 152a can be blown to the other side of the width direction X of the second chamber 220 as much as possible, so that the area far from the air duct structure 100 can be blown by the cold air.

[0098] Referring to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is located at the rear of the second chamber 220.

[0099] The rear of the second chamber 220 is the side of the second chamber 220 away from the access opening 230. In the process of supplying air to the second chamber 220, the user opens the door body 500 of the refrigeration equipment 10 to take and place articles through the access opening 230, which is easy to cause the cold air flowing in the second chamber 220 to overflow from the access opening 230. By setting the third air outlet 152a at the rear of the second chamber 220, the path of the cold air blown by the third air outlet 152a to the access opening 230 can be extended, and the overflow of the cold air from the access opening 230 can be reduced as much as possible, which is beneficial to maintaining the temperature of the second chamber 220.

[0100] Referring to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is located at the top of the second chamber 220 and at the rear of the second chamber 220. The third air outlet 152a of the second air outlet component 150 is in communication with the second air supply opening 123 located at the top of the shell 120 and close to the rear of the shell 120, so that the air blown by the second air supply opening 123 flows to the third air outlet 152a through the shortest path.

[0101] Referring to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is located at the top of the second chamber 220 and at the rear of the second chamber 220. The third air outlet 152a of the second air outlet component 150 is in communication with the second air supply opening 123 located at the top of the shell 120 and close to the rear of the shell 120, so that the air blown by the second air supply opening 123 flows to the third air outlet 152a through the shortest path.

[0102] Referring to Figure 1 and Figure 3In some embodiments, the length direction of the third air outlet 152a is arranged along the width direction of the second cavity 220, so that the cold air of the third air outlet 152a is uniformly distributed in the width direction of the second cavity 220, improving the uniformity of the temperature inside the second cavity 220, thereby improving the freezing effect; the third air outlet 152a is located at the top of the second cavity 220, and the probability of the accumulation of articles to the top of the second cavity 220 is small, and the resistance of the cold air blown out by the third air outlet 152a is small, so that the flow of the cold air blown out by the third air outlet 152a is better; the length direction of the third air outlet 152a is arranged along the width direction of the second cavity 220, so that the cold air blown out by the third air outlet 152a flows more uniformly in the width direction of the second cavity 220, so as to reduce the temperature difference at each position inside the second cavity 220 as much as possible, and reduce the problem of uneven refrigeration or freezing of food caused by temperature difference.

[0103] Please refer to Figure 1 and Figure 3 In some embodiments, the second air outlet component 150 includes a connecting piece 151 and a second air outlet piece 152, the connecting piece 151 communicates the second air supply opening 123 and the second air outlet piece 152; the third air outlet 152a is arranged on the second air outlet piece 152, and the second air outlet piece 152 is arranged side by side with the shell 120 along the width direction X of the shell 120. The connecting piece 151 can be arranged in a curved manner, so that the connecting piece 151 is as close as possible to the inner wall of the second cavity 220, so as to avoid the influence of the connecting piece 151 on the capacity of the second cavity 220 as much as possible.

[0104] Since the second air supply opening 123 is located on the side wall of the shell 120, and the air duct structure 100 is located on one side wall of the second cavity 220, so that the opposite side wall is farthest from the air duct structure 100, thereby making the freezing articles near the opposite side wall receive the least cold air; along the width direction X of the shell 120, the second air outlet piece 152 is arranged spaced apart from the shell 120, and the cold air is blown as far as possible to the side of the shell 120 away from the air duct structure 100 through the second air outlet piece 152, so that the cold air flows to the farthest position as much as possible, thereby freezing the freezing articles farthest from the air duct structure 100.

[0105] The second air outlet member 152 can extend in the width direction X of the shell 120, and the second air outlet member 152 is provided with a third air outlet 152a through which the second air outlet member 152 can send cold air to the second cavity 220 to blow the cold air to a position as far as possible from the air duct structure 100; in order to improve the air sending efficiency of the second air outlet member 152, a plurality of third air outlets 152a can be provided on the second air outlet member 152, and by providing a plurality of third air outlets 152a on the second air outlet member 152, the efficiency of air sending and the uniformity of cold air inside the second cavity 220 can be as high as possible under the premise of reducing the number of parts in the second cavity 220 and reducing the number of openings of the second cavity 220.

[0106] Referring to Figure 1 and Figure 3 In some embodiments, the second air outlet member 150 is arranged at the rear of the second cavity 220, which reduces the occupation of the second air outlet member 150 in the space inside the second cavity 220, so that the second cavity 220 can accommodate as many articles as possible, thereby improving the capacity of the second cavity 220.

[0107] The rear of the second cavity 220 is the side of the second cavity 220 away from the access opening 230, and in the process of sending cold air to the second cavity 220, the user opens the door 500 of the refrigeration equipment 10 to take and place articles through the access opening 230, which is easy to cause the cold air flowing inside the second cavity 220 to overflow from the access opening 230. Arranging the second air outlet member 150 at the rear of the second cavity 220 can prolong the path of the cold air blown by the second air outlet member 150 to the access opening 230, thereby reducing the overflow of cold air from the access opening 230 as much as possible, which is conducive to maintaining the temperature of the second cavity 220.

[0108] Referring to Figure 1 and Figure 3 In some embodiments, the second air outlet member 150 is arranged at the top of the second cavity 220. Since the possibility of placing articles at the top of the second cavity 220 is small, the cold air receives small resistance, so that the flowability of the cold air at the top of the second cavity 220 is large, thereby making the cold air blown from the second air outlet member 150 blow to the other side of the width direction X of the second cavity 220 as much as possible, so that the area far from the air duct structure 100 can be blown by the cold air. In addition, it is difficult for articles to accumulate at the top of the second cavity 220, and the above arrangement can reduce the influence of the second air outlet member 150 on the capacity of the second cavity 220 as much as possible, so that the second cavity 220 can accommodate as many articles as possible.

[0109] Referring to Figure 1 and Figure 3In some embodiments, the second air outlet component 150 is located at the top of the second chamber 220 and at the rear of the second chamber 220, and the access opening 230 is located at the front of the cabinet, so that the influence of the second air outlet component 150 on the user's taking and placing of articles can be minimized; the second air outlet component 150 of the second air outlet component 150 is in communication with the second air outlet 123 located at the top of the shell 120 and close to the rear of the shell 120, so that the air blown out of the second air outlet 123 flows to the second air outlet component 150 through the shortest path.

[0110] Referring to Figure 3 and Figure 7 In some embodiments, the second air outlet component 150 is located at the top of the second chamber 220 and at the rear of the second chamber 220, and the access opening 230 is located at the front of the cabinet, so that the influence of the second air outlet component 150 on the user's taking and placing of articles can be minimized; the second air outlet component 150 of the second air outlet component 150 is in communication with the second air outlet 123 located at the top of the shell 120 and close to the rear of the shell 120, so that the air blown out of the second air outlet 123 flows to the second air outlet component 150 through the shortest path.

[0115] In some embodiments, the air duct structure 100 further comprises a damper assembly 160 installed on the top of the mounting cavity 121 for opening or closing the first air vent 131a.

[0116] In some embodiments, the top of the volute 131 is provided with a mounting groove 131e, and the damper assembly 130 is embedded in the mounting groove 131e to ensure the firmness of the connection between the damper assembly 130 and the volute 131; the slot of the mounting groove 131e forms the first air vent 131a, which facilitates the damper assembly 130 to control the opening or closing of the first air vent 131a.
