[0042] The refrigeration equipment is a professional storage tool for storing various frozen goods, which can keep food or other goods in a 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.

[0043] The air duct structure is used to supply air to the chamber. For example, in a refrigeration device, cold air is blown to the chamber of the refrigeration device through the air duct structure. Due to the fewer air supply openings on the air duct structure or the too concentrated distribution, the distribution of cold air in the chamber is uneven, and the refrigeration effect is reduced.

[0044] The present application will be described below in conjunction with the accompanying drawings and specific embodiments:

[0045] Please refer to Figure 1 and Figure 3 The air duct structure 100 provided by the embodiments of the present application is mainly applied to a refrigeration device 10. The air duct structure 100 provided by the embodiments of the present application is used to supply air to the refrigeration device 10. The refrigeration device 10 is internally provided with multiple chambers, for example, 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 device 10, so as to achieve the refrigeration effect.

[0046] Among them, the refrigeration device 10 can be a refrigerator or a freezer. In the embodiments of the present application, for the convenience of description, the refrigeration device 10 is taken as an example to illustrate the refrigeration device 10. When the refrigeration device 10 is other equipment, it can be inferred by analogy.

[0047] The refrigeration device 10 is roughly a cuboid. For the convenience of description, the height direction Z, the width direction X and the thickness direction Y are defined respectively. Among them, in the use state of the refrigeration device 10, the vertical direction is the height direction Z, and the projection of the refrigeration device 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.

[0048] For the convenience of description, the six directions of up, down, left, right, front and back are defined. Among them, the two directions in the height direction Z are up and down, and the two directions in the width direction X are left and right respectively. In the thickness direction Y, the connection between the door body 500 and the box body is the front, and the opposite side is the back.

[0049] Please refer to Figure 2 and Figure 3In the embodiment of the present application, the air duct structure 100 comprises a shell 120, a fan assembly 130 and a second air outlet component 150. The shell 120 has a mounting cavity 121 with a mounting side wall 121b having a plurality of second air supply openings 123 for supplying air to the second cavity 220. The second air outlet component 150 is located in the second cavity and has a third air outlet 152a in communication with at least one second air supply opening 123. The second air outlet component 150 supplies air to the second cavity 220 through the third air outlet 152a. The fan assembly 130 is arranged in the mounting cavity 121 and can cause the air in the mounting cavity 121 to blow towards the second cavity 220 through the second air supply opening 123 and / or the third air outlet 152a. The second air outlet component 150 supplies air to the second cavity 220 through the second air supply opening 123 so as to blow cold air to as many areas of the second cavity 220 as possible. Since the second air supply opening 123 is located on the mounting side wall 121b of the shell 120 and the air duct structure 100 is located on one side wall of the second cavity 220, the opposite side wall is farthest from the air duct structure 100, so that the frozen items near the opposite side wall receive the least amount of cold air. The second air supply opening 123 is located on the side wall of the mounting cavity 121, so the second air supply opening 123 can directly supply cold air to the second cavity 220 through the second air supply opening 123 on the mounting side wall 121b, reducing the path of the cold air flow and increasing the air outlet efficiency.

[0050] The third air outlet 152a is located at the rear of the second cavity 220. The rear of the second cavity 220 refers to the side of the second cavity 220 away from the access opening 230. When the user opens the door 500 of the refrigeration equipment 10 to take or place an article through the access opening 230, the cold air flowing in the second cavity 220 is likely to overflow from the access opening 230. By arranging the third air outlet 152a at the rear of the second cavity 220, the path of the cold air blown out of the third air outlet 152a to the access opening 230 is extended, and the overflow of the cold air from the access opening 230 is minimized, which is conducive to maintaining the temperature of the second cavity 220. That is, in the embodiment of the present application, the second air supply opening 123 is arranged on the mounting side wall 121b of the shell 120, and the air duct structure 100 is located on one side wall of the second cavity 220, that is, the second air supply opening 123 is located on one side of the second cavity 220. The third air outlet 152a is located at the rear of the second cavity 220, and the fan assembly 130 can blow air into the second cavity 220 through at least one of the third air outlet 152a and the second air supply opening 123, so that the entire air duct structure 100 can blow air into the second cavity 220 from the side and the rear of the second cavity 220, that is, the second cavity 220 can be blown from different directions. The air entering the second cavity 220 can be blown to different positions in the second cavity 220 as evenly as possible, thereby improving the refrigeration effect.

[0051] 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 equipment 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 cavity 210, or on the side of the shell 120 facing the second cavity 220.

[0052] Please refer to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is spaced apart from the shell 120 along the width direction X of the shell 120.

[0053] The third air outlet 152a is spaced apart from the shell 120 along the width direction X of the shell 120, and cold air is blown out of the third air outlet 152a as far as possible to the side of the shell 120 away from the air duct structure 100, so that the cold air flows to a relatively far position, thereby freezing the frozen articles that are relatively far away from the air duct structure 100.

[0054] In one embodiment, the at least two second air outlets 123 are arranged at intervals along the height direction Z of the shell 120. The second air outlets 123 are multiple, and the 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 outlets 123 can be blown to different height positions of the second chamber 220, so that the cold air flows in different heights of the second chamber 220, covers the areas of different heights of the second chamber 220 as much as possible, thereby improving the uniformity of the cold air in the second chamber 220, and improving the freezing effect. By arranging multiple second air outlets 123, the efficiency of cold air delivery can be improved, thereby improving the freezing effect.

[0055] In some embodiments, the installation cavity 121 has an installation top wall 121a, and the installation top wall 121a has a first air outlet 122 for air supply to the first chamber 210; the fan assembly 130 can make the air in the installation cavity 121 blow to the first chamber 210 through the first air outlet 122.

[0056] The air duct structure 100 is applied to the refrigeration equipment 10, is installed in the box body of the refrigeration equipment 10, and 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 articles after being cooled by the evaporator, that is, the air duct structure 100 can be considered to be mainly used for blowing cold air to the refrigeration equipment 10, so that the cold air can circulate in the refrigeration equipment 10, so as to ensure that the temperature in the same chamber of the refrigeration equipment 10 is substantially the same as much as possible, and reduce the temperature difference in the same chamber.

[0057] Since the thickness of the air duct structure 100 is smaller than the width, and 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 surface 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, so as to improve the uniformity of freezing as much as possible.

[0058] 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.

[0059] The first air outlet 122 is located on the top wall of the installation cavity 121, and the second air outlet 123 is located on the side wall of the installation cavity 121. The cold air in the installation cavity 121 flows in different directions, reduces the possibility of air flow between the first chamber 210 and the second chamber 220, and insulates the first chamber 210 and the second chamber 220 as much as possible, reduces the heat transfer between the first chamber 210 and the second chamber 220, and is beneficial to maintain the temperature difference between the first chamber 210 and the second chamber 220.

[0060] The installation top wall 121a refers to the upper wall of the shell 120, that is, in the normal use state of the refrigeration equipment 10, the installation top wall 121a is located on the upper side of the shell 120.

[0061] The shell 120 is the basic component of the air duct structure 100, which can provide an installation basis for other structures of the air duct structure 100. The fan assembly 130 and other structures can be installed on the shell 120, so that the air duct structure 100 can form a whole, and the installation and transportation of the air duct structure 100 can be facilitated. At the same time, the shell 120 can also protect the fan assembly 130 and other structures, and reduce the damage of external structures to the fan assembly 130 and other structures.

[0062] In the embodiment of the present application, in order to facilitate description, the height direction Z, the width direction X and the thickness direction Y of the shell 120 are defined.

[0063] The fan assembly 130 is used to drive the air flow, so that the air in the installation 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.

[0064] The first air outlet 122 is located on the top wall of the installation cavity 121, and the cold air flows out of the installation cavity 121 through the first air outlet 122 and then blows to the first chamber 210, avoiding that the installation cavity 121 is directly communicated with the first chamber 210, and reducing the influence of the temperature of the installation cavity 121 on the first chamber 210; the first air outlet 122 of the installation top wall 121a blows air to the first chamber 210, so as to avoid opening holes between the first chamber 210 and the installation cavity 121, improve the heat insulation effect of the first chamber 210, and be beneficial to maintaining the temperature of the first chamber 210.

[0065] 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 that of the first chamber 210, the second chamber 220 reaches the 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, the 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 the 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, and the embodiments of the present application do not make special limitations thereon.

[0066] 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 is suitable for storing different types of storage requirements, and the variable-temperature range of the variable-temperature compartment is -3-5°C. 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.

[0067] 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.

[0068] The first air outlet component 140 can be used to deliver air to the first chamber 210, without opening an air outlet on the side wall of the mounting cavity 121 facing the second chamber 220. In the case that the air duct structure 100 stops delivering air to the second chamber 220, the influence of the air duct structure 100 on the second chamber 220 can be reduced, thereby facilitating the maintenance of the temperature of the second chamber 220. By delivering air to the first chamber 210 through the first air outlet component 140, the air inlet path of the first chamber 210 is single-controllable, thereby facilitating the control of the temperature of the first chamber 210.

[0069] The first air outlet component 140 is located outside the mounting cavity 121, thereby avoiding occupying the space of the mounting cavity 121. By using the first air outlet component 140, the direct connection between the second chamber 220 and the air duct structure 100 can be reduced, thereby improving the heat insulation effect of the second chamber 220 without delivering air to the second chamber 220.

[0070] Please refer toFigure 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 from the first air outlet 122 to enter the first chamber 210 through at least one of the first air outlet 143a and the second air outlet 143b.

[0071] By supplying air to the first chamber 210 through the first air outlet 143a and the second air outlet 143b, the efficiency of supplying air to the first chamber 210 can be increased; 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, so that air can be supplied to the first chamber 210 from multiple directions, making the airflow inside the first chamber 210 more uniform, reducing the temperature difference at each position inside the first chamber 210, and reducing the problem of uneven refrigeration or freezing of food caused by temperature difference.

[0072] 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, and through which articles can be taken out of the first chamber 210 or the second chamber 220, or 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 a user takes or places articles through the taking and placing opening 230, cold air may overflow from the taking and placing opening 230; by locating the second air outlet 143b at the rear of the first chamber 210, the possibility of cold air overflowing from the taking and placing opening 230 can be reduced, and energy can be saved. The rear of the first chamber 210 is the side of the first chamber 210 farthest from the taking and placing opening 230.

[0073] The air first flows 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.

[0074] The first return air outlet 124 and the second return air outlet 125 are arranged on the mounting side wall 121b of the mounting cavity 121; the first return air outlet 124 communicates 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 communicates the second chamber 220, and the gas in the second chamber 220 enters the mounting cavity 121 through the second return air outlet 125.

[0075] Please refer to Figure 1In some embodiments, the height of the second air outlet 143b is lower than the height of the first air outlet 143a.

[0076] 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. The second air outlet 143b is arranged at the middle region of the first chamber 210, so that the cold air can be blown at different height positions in the first chamber 210, so that the cold air can be blown more uniformly to different regions of the first chamber 210, and the refrigeration effect is better.

[0077] The first return air inlet 124 is close to the bottom of the first chamber 210, so that the cold air can form multiple different circulation regions, improving the refrigeration effect. Specifically, in the process of placing articles, users basically stack from bottom to top, and more articles are needed at the bottom, so more cold energy is needed. The second air outlet 143b is arranged between the first air outlet 143a and the first return air inlet 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 more uniformly to different regions in the first chamber 210, and the refrigeration effect is better.

[0078] 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.

[0079] 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 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 article accumulation to the top of the first chamber 210 is small, so the resistance of the cold air blown out by the first air outlet 143a is small, and 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, so as to reduce the temperature difference at each position inside the first chamber 210 as much as possible, and reduce the problem of uneven refrigeration or freezing of food caused by temperature difference.

[0080] The length direction of the second air outlet 143b is arranged along the width direction of the first cavity 210, so that the cold air of the second air outlet 143b is uniformly distributed in the width direction of the first cavity 210, the uniformity of the temperature inside the first cavity 210 is improved, and the refrigeration effect is improved; the second air outlet 143b is located at the rear of the first cavity 210, so that the cold air blown by the second air outlet 143b flows from the rear to the front of the first cavity 210; the length direction of the second air outlet 143b is arranged along the width direction of the first cavity 210, so that the cold air blown by the first air outlet 143a flows more uniformly in the width direction of the first cavity 210, the cold air blown by the first air outlet 143a has a large range of action in the width direction of the first cavity 210, the temperature difference between each position inside the first cavity 210 is reduced as much as possible, and the problem of uneven refrigeration or freezing of food caused by temperature difference is reduced.

[0081] The length direction of the first air outlet 143a can be arranged along the width direction of the first cavity 210, or the length direction of the second air outlet 143b can be arranged along the width direction of the first cavity 210; in the embodiment of the present application, the length directions of the first air outlet 143a and the second air outlet 143b are both arranged along the width direction of the first cavity 210, so as to make the cold air act on each area inside the first cavity 210 as much as possible.

[0082] In some embodiments, a fourth air outlet 143d is formed between the first air outlet component 140 and the rear wall of the first cavity 210, the fourth air outlet 143d faces the bottom of the first cavity 210, so that the cold air can be blown to the bottom of the first cavity 210 to cool the food at the bottom of the first cavity 210; the fourth air outlet 143d can increase the flow direction of the cold air in the first cavity 210, so that the distribution of the cold air inside the first cavity 210 is more uniform, and the temperature difference between each part in the first cavity 210 is reduced.

[0083] Please refer to Figure 1 and Figure 4 In some embodiments, the first air outlet component 140 includes a body piece 142 and a first air outlet piece 143, the ventilation cavity 141 is at least partially formed in the body piece 142, the first air outlet piece 143 is arranged side by side with the shell 120, the body piece 142 communicates the first air outlet piece 143 and the first air supply port 122, and the first air outlet piece 143 is used to supply air to the first cavity 210.

[0084] The first air outlet piece 143 is arranged side by side with the shell 120, and the first air outlet piece 143 can guide the air flow out of the first air supply port 122 at the top of the mounting cavity 121 to the first cavity 210 through the body piece 142, so as to realize the air supply of the first cavity 210.

[0085] The first chamber 210 is formed on one side of the air duct structure 100, and the first air outlet 143 is arranged side by side with the shell 120, so that the first air outlet 143 can extend into the interior of the first chamber 210, which is conducive to precise air supply to the first chamber 210; the first air outlet 143a and the second air outlet 143b are arranged on the first air outlet 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 143, so that the flow of air in the first chamber 210 is more uniform.

[0086] By air supply to the first chamber 210 through the first air outlet 143, multiple air outlets at different heights can be arranged on the first air outlet 143, for example, multiple first air outlets 143a or second air outlets 143b are arranged on the first air outlet 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.

[0087] The ventilation cavity 141 is at least partially located in the body part 142, so that the cold air in the mounting cavity 121 can enter the first air outlet 143 arranged side by side with the shell 120 through the body part 142, and the cold air in the mounting cavity 121 can be sent to the first chamber 210 without opening a hole between the first chamber 210 and the mounting cavity 121. The ventilation cavity 141 can be entirely arranged in the body part 142, or a part of the ventilation cavity 141 can be arranged in the body part 142 and the other part can be arranged in the first air outlet 143, as long as the body part 142 can send the cold air in the mounting cavity 121 to the first air outlet 143.

[0088] Please refer to Figure 1 and Figure 4 In some embodiments, the first air outlet 143 includes a first air outlet section 144 and a second air outlet section 145 connected to each other, the first air outlet section 144 is connected to the body part 142, the first air outlet section 144 is located at the top of the first chamber 210, the second air outlet section 145 is located at the rear of the first chamber 210, and the first air outlet 143 supplies air to the first chamber 210 through at least one of the first air outlet section 144 and the second air outlet section 145.

[0089] The first air outlet member 143 blows air to the first chamber 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 chamber 210, and the 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 chamber 210, and the second air outlet 143b can be arranged on the second air outlet section 145. In this way, air is blown to the first chamber 210 from multiple directions, so that the airflow inside the first chamber 210 is more uniform, the temperature difference at different positions inside the first chamber 210 is reduced, and the problem of uneven refrigeration or freezing of food due to temperature difference is reduced.

[0090] The first air outlet section 144 and the second air outlet section 145 are connected to form the first air outlet member 143. During installation, the relative positional relationship between the first air outlet member 143 and the second air outlet member 152 does not need to be adjusted, which facilitates installation. After the cold air in the body member 142 passes through the first air outlet section 144, part of the cold air is blown to the first chamber 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 chamber 210 through the second air outlet 143b. The ventilation cavity 141 is partially located in the body member 142, partially located in the first air outlet section 144, and partially located in the second air outlet section 145. In this way, the cold air passing through the first air outlet 143a and the second air outlet 143b from the first air outlet 122 can enter the first chamber 210 through the ventilation cavity 141.

[0091] 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. By using only one first air outlet member 143, air can be blown to the first chamber 210 from different directions, which can minimize the number of components inside the first chamber 210 and improve the integration of the air duct structure 100. The first chamber 210 only needs to have one hole to connect the first air outlet member 140, which can reduce the number of holes in the inner wall of the first chamber 210 and improve the heat insulation effect of the first chamber 210. In addition, the above arrangement can reduce the space occupied by the first air outlet member 143 in the first chamber 210, so that the first chamber 210 can accommodate as many items as possible and improve the capacity of the first chamber 210.

[0092] Please refer to Figures 4 to 6 In some embodiments, one of the first air outlet member 143 and the body member 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.

[0093] The first air outlet piece 143 and the body piece 142 are connected through the cooperation of the engaging protrusion 143c and the engaging groove 142a; the connection between the first air outlet piece 143 and the body piece 142 is simplified by simply aligning and pressing or buckling the first air outlet piece 143 and the body piece 142, so that the connection between the first air outlet piece 143 and the body piece 142 is more simple and reliable, and the stability of the structure is improved.

[0094] In some embodiments, the body piece 142 is provided with the engaging groove 142a, and the first air outlet piece 143 is provided with the engaging protrusion 143c; the body piece 142 is provided with the barb 142c on the side facing the first air outlet piece 143, and the engaging groove 142a is formed between the barb 142c and the body piece 142; the body piece 142 is provided with the elastic piece 142d on the side of the barb 142c, and the engaging groove 142a is provided on the elastic piece 142d.

[0095] Specifically, in the cooperation process, the elastic piece 142d is bent to make the second buckle extend between the barb 142c and the elastic piece 142d, so that the second buckle is buckled in the second groove; the elastic piece 142d is released, and the elastic 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 elastic piece 142d to facilitate manual bending of the elastic piece 142d.

[0096] Please refer to Figure 1 and Figure 4 In 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 holes 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, thereby minimizing the influence of the mounting cavity 121 on the temperature of the first chamber 210. 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 increased as much as possible to store more items.

[0097] Please refer to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is located at the top of the shell 120. Since the possibility of placing items at the top of the second chamber 220 is small, the resistance to cold air is small, so that the flowability of cold air at the top of the second chamber 220 is large, thereby making the cold air blown from the third air outlet 152a blow 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] Since the third air outlet 152a is arranged on the second air outlet component 150, the third air outlet 152a is located at the top of the shell 120, which means that the third air outlet 152a is located in the top region of the shell 120.

[0099] Please refer 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, and the third air outlet 152a 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 by the second air outlet 123 flows to the third air outlet 152a through the shortest path.

[0100] Please refer to Figure 1 and Figure 3 In some embodiments, the air outlet direction of the third air outlet 152a is arranged at an angle with the air outlet direction of the second air outlet 123, that is, the air outlet direction of the third air outlet 152a intersects with the air outlet direction of the second air outlet 123, so that the cold air can be blown from different directions to the second chamber 220, improving the uniformity of the cold air flowing in the second chamber 220, thereby improving the freezing effect inside the second chamber 220.

[0101] Please refer to Figure 1 and Figure 3 In some embodiments, the length direction of the third air outlet 152a is arranged along the width direction of the second chamber 220, so that the cold air blown out by the third air outlet 152a is uniformly distributed in the width direction of the second chamber 220, improving the uniformity of the temperature inside the second chamber 220, thereby improving the freezing effect; the third air outlet 152a is located at the top of the second chamber 220, and the probability of the accumulation of goods to the top of the second chamber 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 chamber 220, so that the cold air blown out by the third air outlet 152a flows more uniformly in the width direction of the second chamber 220, so as to reduce the temperature difference at each position inside the second chamber 220 as much as possible, and reduce the problem of uneven refrigeration or freezing of food caused by temperature difference.

[0102] Please refer to Figure 1 and Figure 3In some embodiments, the second air outlet component 150 comprises a connecting piece 151 and a second air outlet piece 152, the connecting piece 151 connects the second air outlet 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.

[0103] 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 cavity 220, so that the opposite side wall is farthest from the air duct structure 100, thereby making the frozen items near the opposite side wall receive the least cold air; the second air outlet piece 152 is arranged spaced apart from the shell 120 along the width direction X of the shell 120, and cold air is blown to the side of the shell 120 farthest 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 frozen items farthest from the air duct structure 100.

[0104] The second air outlet piece 152 can extend in the width direction X of the shell 120, the second air outlet piece 152 is provided with the third air outlet 152a, and the second air outlet piece 152 can blow air to the second cavity 220 through the third air outlet 152a, so as to blow cold air to the farthest position from the air duct structure 100 as much as possible; in order to improve the air blowing efficiency of the second air outlet piece 152, a plurality of third air outlets 152a can be arranged on the second air outlet piece 152, and a plurality of third air outlets 152a can be arranged on the second air outlet piece 152, so as to increase the air blowing efficiency and the uniformity of the cold air in the second cavity 220 as much 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.

[0105] Please refer to Figure 1 and Figure 3 In some embodiments, the second air outlet component 150 is arranged at the rear of the second cavity 220, which reduces the occupation of the second air outlet component 150 to the space in the second cavity 220, so that the second cavity 220 can accommodate as many items as possible, thereby improving the capacity of the second cavity 220.

[0106] The rear of the second chamber 220 is the side of the second chamber 220 away from the access opening 230. During the process of air supply to the second chamber 220, the user opens the door body 500 of the refrigeration equipment 10 to take or place the 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. The second air outlet component 150 is arranged at the rear of the second chamber 220, which can prolong the path of the cold air blown by the second air outlet component 150 to the access opening 230, and reduce the overflow of the cold air from the access opening 230 as much as possible, which is conducive to maintaining the temperature of the second chamber 220.

[0107] Referring to Figure 1 and Figure 3 In some embodiments, the second air outlet component 150 is arranged at the top of the second chamber 220. Since the possibility of placing articles at the top of the second chamber 220 is small, the cold air is subjected to small resistance, so that the flowability of the cold air at the top of the second chamber 220 is large, and thus the cold air blown from the second air outlet component 150 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 away 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 chamber 220, and the above arrangement can reduce the influence of the second air outlet component 150 on the capacity of the second chamber 220 as much as possible, so that the second chamber 220 can accommodate as many articles as possible.

[0108] Referring to Figure 1 and Figure 3 In some embodiments, the second air outlet component 150 is arranged at the top of the second chamber 220 and at the rear of the second chamber 220, and the access opening 230 is arranged at the front of the cabinet, which can reduce the influence of the second air outlet component 150 on the user's taking or placing of articles to the greatest extent; the second air outlet component 150 of the second air outlet component 150 is in communication with the second air supply opening 123 arranged 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 second air outlet component 150 through the shortest path.

[0109] Referring to Figure 3 and Figure 7In some embodiments, the second air outlet 152 is fixedly connected to at least one of the top wall and the rear wall of the second chamber 220, such that the second air outlet 152 is fixed in the second chamber 220 and located at the top and the rear of the second chamber 220; the second air outlet 152 has a first fixed portion 152b and a second fixed portion 152c; the first fixed portion 152b extends outward from the edge of the top of the first air outlet 143 and abuts against the top wall of the second chamber 220, and the first fixed portion 152b and the top wall of the first chamber 210 can be connected by screwing or buckling; the second fixed portion 152c extends outward from the edge of the top of the first air outlet 143 and abuts against the rear wall of the second chamber 220, and the second fixed portion 152c and the rear wall of the first chamber 210 can be connected by screwing or buckling.

[0110] Referring to Figure 7 and Figure 8 In some embodiments, the fan assembly 130 further comprises a volute 131 and a fan 132 installed in the volute 131; the volute 131 is provided with a first air vent 131a and a second air vent 131b; the first air vent 131a is in communication with the first air outlet 122; and the second air vent 131b is in communication with the second air outlet 123.

[0111] By providing the first air vent 131a and the second air vent 131b on the volute 131, the air outlet efficiency of the volute 131 is improved, and the air supply is accelerated; the fan 132 as a power source can drive the gas flow in the volute 131 to blow the cold air through the first air vent 131a to the first chamber 210 via the first air outlet 122, or blow the cold air through the second air vent 131b to the second chamber 220 via the second air outlet 123. The volute 131 supplies air to the first chamber 210 and the second chamber 220 through the provision of multiple different air vents, so as to control the air supply state of different chambers.

[0112] The volute 131 is provided with an air inlet 131d, which is substantially circular. The volute 131 can be installed at the air inlet 131d.

[0113] Referring to Figure 2 and Figure 7 In some embodiments, the first air vent 131a is arranged close to the rear wall of the first chamber 210; the cold air is blown to the first chamber 210 via the first air vent 131a, the first air outlet 122 and the second air outlet 143b of the first air outlet component 140, and the second air outlet 143b is located at the rear wall of the first chamber 210; the first air vent 131a is arranged close to the rear wall of the first chamber 210, so as to minimize the path of the cold air flowing to the first chamber 210 and improve the air outlet efficiency.

[0114] In some embodiments, the air duct structure 100 further comprises a damper assembly 160 installed on the volute 131 for opening or closing the first air vent 131a. The opening and closing of the first air vent 131a can be controlled through the damper assembly 160 to control the amount of cold air delivered to the first chamber 210, thereby controlling the temperature of the first chamber 210. The damper assembly 160 is installed on the volute 131, which can more accurately adjust the amount of cold air entering the first chamber 210, improve the efficiency of the air duct structure 100, and more quickly control the amount of cold air in the first chamber 210. In addition, the damper directly controls the first air vent 131a, which can timely prevent cold air from entering the first chamber 210 and reduce energy loss.

[0115] 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 opening or closing of the first air vent 131a by the damper assembly 130.

[0116] In some embodiments, the bottom of the mounting groove 131e is communicated with the inside of the volute 131, the sidewall of the mounting groove 131e is provided with a second air vent 131b for delivering air to the second chamber, and the inner wall of the mounting groove 131e has a wind guide surface 131f for guiding the air to the second air vent 131b, so that the air in the volute 131 can flow to the second chamber 220 through the wind guide surface 131f and the second air vent 131b. The wind guide surface 131f can be an inclined surface or an arc surface, as long as it can guide the air to flow to the second air vent 131b.

[0117] The air duct assembly comprises a main body 161 and a cover plate 162. The main body 161 is provided with a ventilation opening communicated with the first air inlet 122 and the first air vent 131a. The cover plate 162 can be covered on the ventilation opening to block the first air inlet 122 and the first air vent 131a, so that the cold air cannot blow to the first chamber 210. When the cover plate 162 is opened, the cover plate 162 no longer blocks the ventilation opening, so that the first air inlet 122 and the first air vent 131a are communicated, and the cold air blows to the first chamber 210 through the first air vent 131a, the first air inlet 122 and the first air outlet component 140. The main body 161 comprises a first connecting section and a second connecting section connected to each other. The first connecting section is partially arranged in the first air inlet 122, and the second connecting section is arranged in the first air vent 131a, so that the first air inlet 122 and the first air vent 131a are communicated.

[0118] Please refer to Figure 2 and Figure 3In some embodiments, a sealing member 163 is arranged between the damper assembly 160 and the first air outlet component 140. The sealing member 163 can effectively prevent cold air leakage and maintain the air duct structure 100 in a closed state. In addition, the sealing member 163 can prevent external dust and impurities from entering through the joint between the damper assembly 160 and the first air outlet component 140. Generally, the sealing member 163 can be a sealing gasket.

[0119] Referring to Figure 8 In some embodiments, the volute 131 is provided with a second air vent 131b, which is in communication with the second air outlet 123 to supply air to the second chamber 220. The second air outlet 123 is located on the side wall of the shell 120. By arranging the second air vent 131b on the side wall of the volute 131, the path between the second air vent 131b and the second air outlet 123 can be shortened, energy loss can be reduced, and air supply efficiency can be improved.

[0120] In some embodiments, the second air vent 131b is a plurality of second air vents, and each second air vent 131b is in communication with a corresponding second air outlet 123, so that cold air can flow to the second chamber 220 through the second air vent 131b and the second air outlet 123. At least two second air outlets 123 are arranged at intervals along the height direction Z of the shell 120. By arranging at least two second air outlets 123 at intervals along the height direction Z of the shell 120, the path between the second air outlet 123 and the second air vent 131b can be shortened as much as possible, the air duct can be reduced, and the air supply efficiency can be improved.

[0121] Referring to Figure 2 and Figure 3 In some embodiments, the volute 131 is provided with an extension 133 on the side facing the second chamber 220, and the second air vent 131b is arranged on the extension 133. The extension 133 is at least partially located in the second air outlet 123. By extending the extension 133 to the second air outlet 123, the second air vent 131b and the second air outlet 123 are in communication, so that the cold air in the volute 131 can be blown to the second chamber 220. The extension 133 is at least partially located in the second air outlet 123, so that the cold air blown out of the second air vent 131b can be accurately blown to the second chamber 220 through the second air outlet 123, and the energy loss of the air can be reduced. The extension 133 can also extend from one side of the second air outlet 123 to the second chamber 220, so that the second air vent 131b can directly supply air to the second chamber 220. The extension 133 can also be arranged close to the side wall of the shell 120, and a gap is formed between the second air vent 131b and the second air outlet 123. Only the cold air blown out of the second air vent 131b can flow to the second chamber 220 through the second air outlet 123. Of course, in other embodiments, the second air vent 131b and the second air outlet 123 can also be in communication through an air duct, and the embodiments of the present application are not limited in this regard.

The direction of the long side is the width direction X, and the direction of the wide side is the thickness direction Y.

[0132] 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 cabinet, and the air duct structure 100 can be installed in the middle of the cabinet in the width direction X to divide the cabinet into the first chamber 210 and the second chamber 220. The specific installation position of the air duct structure 100 can be adjusted according to the size ratio of the first chamber 210 and the second chamber 220. By dividing the first chamber 210 and the second chamber 220 by the air duct structure 100, the air duct structure 100 can isolate the first chamber 210 and the second chamber 220, and also meet the air supply requirements of the first chamber 210 and the second chamber 220, so that the structure of the refrigeration equipment 10 is more reasonable; the air duct structure 100 is located between the first chamber 210 and the second chamber 220, which facilitates air supply to the first chamber 210 and the second chamber 220 at the same time, reduces the air supply path, and improves the air supply efficiency.
