[0044] The refrigeration equipment is a professional storage tool for storing various refrigerated items, which can keep food or other items in a refrigerated state. The refrigeration system of the refrigeration equipment is composed of a compressor, a condenser, a capillary, an evaporator and the like. By continuously circulating the refrigerant, the heat inside the freezer is brought outside the freezer 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 a wind channel structure in the inner tank. Since the air supply port on the wind channel structure is usually arranged on the side wall of the wind channel structure, the heat insulation effect of the chamber is affected, which is not conducive to independent temperature adjustment of each chamber.

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

[0047] Please refer to Figure 1 and Figure 3 The refrigeration equipment provided in the embodiments of the present application includes a box body and a wind channel structure 100. The wind channel structure 100 is arranged in the box body to divide the box body into a first chamber 210 and a second chamber 220. The wind channel structure 100 is used to supply air to the refrigeration equipment 10. The wind channel structure 100 enables cold air to flow in the first chamber 210 and the second chamber 220 in the refrigeration equipment 10 to achieve a refrigeration 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 illustration for the convenience of description. When the refrigeration equipment 10 is other equipment, it can be inferred by analogy.

[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 box body is the front, and the opposite side is the back.

[0051] Please refer to Figure 3 and Figure 7In the embodiment of the present application, the air duct structure 100 comprises a shell 120, a fan assembly 130 and an evaporator 300. The shell 120 has a mounting cavity 121. 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 used to send air to the first chamber 210, and the second air vent 131b is used to send air to the second chamber 220. The evaporator 300 is installed in the mounting cavity 121 and is used to absorb heat in the mounting cavity 121 to form cold air.

[0052] 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 through the first air outlet 122, or blow the cold air through the second air vent 131b to the second chamber 220. The volute 131 supplies air to the first chamber 210 and the second chamber 220 through different air vents, so as to control the air supply state of different chambers.

[0053] 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.

[0054] Please refer to Figure 9 and Figure 10 The refrigeration equipment 10 is mainly used for refrigerating goods. The box body is the main structure 161 of the entire refrigeration equipment 10, which can provide a mounting basis for the air duct structure 100, the compressor, the evaporator 300, the condenser and other structures, and can also protect the above-mentioned electronic components and the like.

[0055] The box body is substantially a cuboid. In order to facilitate description, the height direction Z, the width direction X and the thickness direction Y are defined respectively. In the use state of the refrigeration equipment 10, the vertical direction is the height direction Z, and the projection of the main body 161 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.

[0056] 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, the air duct structure 100 can be installed on one side of the cabinet in the width direction X of the refrigeration equipment 10, so that the air blown in 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 in the shell 120 can cover the entire inside of the shell 120, and the uniformity of freezing is improved as much as possible. The air duct structure 100 can also 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 using the air duct structure 100 to divide the first chamber 210 and the second chamber 220, the air duct structure 100 can not only isolate the first chamber 210 and the second chamber 220, but 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.

[0057] 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 is arranged in the installation cavity 121, and can make the air in the installation cavity 121 blow to the first chamber 210 through the first air outlet 122.

[0058] The air duct structure 100 is applied to the refrigeration equipment 10 and installed in the cabinet of the refrigeration equipment 10, which 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. It can be considered that the air duct structure 100 is mainly used to blow 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 and reduce the temperature difference in the same chamber.

[0059] 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. The installation 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 installation top wall 121a is located on the left side or the right side of the shell 120. The installation 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.

[0060] 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.

[0061] In the embodiments 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.

[0062] 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.

[0063] The first air outlet 122 is located on the top wall of the mounting cavity 121, and the first air outlet 122 is in communication with the first air outlet 122. The cold air flows through the first air outlet 131a, the first air outlet 122, and then flows out of the mounting cavity 121 to the first chamber 210, so as to avoid the direct communication between the mounting cavity 121 and the first chamber 210, and to reduce 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 supply 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.

[0064] 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. The second air outlet 123 is used to supply air to the second chamber 220, and the second air outlet 123 is in communication with the second air outlet 123. The second air outlet 123 blows to the second chamber 220.

[0065] The second air outlet 123 is located on the side wall of the mounting cavity 121, and the second air outlet 123 can directly supply cold air to the second chamber 220 through the second air outlet 123 on the mounting side wall 121b, thereby reducing the flow path of the cold air and increasing the air supply 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. The cold air in the mounting cavity 121 flows in different directions, which reduces the possibility of air flow between the first chamber 210 and the second chamber 220, so as to isolate the first chamber 210 and the second chamber 220 as much as possible, reduce the heat transfer between the first chamber 210 and the second chamber 220, and be conducive to maintaining the temperature difference between the first chamber 210 and the second chamber 220.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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 to different regions of the first chamber 210 at different height positions, so that the refrigeration effect is better.

[0078] 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, users basically stack from bottom to top when placing articles, and more articles are placed 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 to different regions of the first chamber 210 more uniformly, so that the refrigeration effect is better.

[0079] 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.

[0080] 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.

[0081] 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 out 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 out by the first air outlet 143a flows more uniformly in the width direction of the first cavity 210, the cold air blown out 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.

[0082] 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.

[0083] 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 cold air is more uniformly distributed inside the first cavity 210, and the temperature difference between each part in the first cavity 210 is reduced.

[0084] 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, and the body piece 142 communicates the first air outlet piece 143 and the first air supply port 122. The first air outlet piece 143 is used to supply air to the first cavity 210.

[0085] 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.

[0086] 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.

[0087] By supplying air 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 maintaining the temperature of the first chamber 210.

[0088] 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. The cold air in the mounting cavity 121 can be supplied 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 supply the cold air in the mounting cavity 121 to the first air outlet 143.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] Please refer to Figure 4 to Figure 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] Please refer to Figure 1 and Figure 4 In some embodiments, the body piece 142 is located outside the first cavity 210, and the installation cavity 121 and the first cavity 210 can be connected through the body piece 142, avoiding opening a hole between the installation cavity 121 and the first cavity 210, so that the first cavity 210 is independent of the installation cavity 121, and the installation cavity 121 and the first cavity 210 are not directly connected, thereby minimizing the influence of the installation cavity 121 on the temperature of the first cavity 210. By arranging the body piece 142 outside the first cavity 210, the space occupied by the body piece 142 in the first cavity 210 can be reduced, and the capacity of the first cavity 210 can be increased as much as possible to store more items.

[0098] Please refer 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 cavity 220, so that the cold air flows in different heights of the second cavity 220, and covers as much as possible the areas of different heights of the second cavity 220, thereby improving the uniformity of the cold air in the second cavity 220, and 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.

[0099] Please refer toFigure 1 And Figure 3 In some embodiments, the air duct structure 100 further comprises a second air outlet component 150, the second air outlet component 150 has a third air outlet 152a, the third air outlet 152a is in communication with the second air outlet 123, and the third air outlet 152a is spaced apart from the shell 120 along the width direction X of the shell 120.

[0100] The second air outlet component 150 sends the air passing through the second air outlet 123 to the second cavity 220 through the third air outlet 152a, so as to make the cold air blow to each area of the second cavity 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 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 third air outlet 152a is spaced apart from the shell 120 along the width direction X of the shell 120, and the cold air is blown to the side of the shell 120 farthest from the air duct structure 100 through the third air outlet 152a, so as to make the cold air flow to the farthest position as much as possible, thereby freezing the frozen items farthest from the air duct structure 100.

[0101] 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 there is less possibility of placing items at the top of the second cavity 220, the cold air receives less 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 out of the third air outlet 152a blow to the other side of the width direction X of the second cavity 220 as much as possible, so that the area farthest from the air duct structure 100 can be blown by the cold air.

[0102] Please refer to Figure 1 And Figure 3 In some embodiments, the third air outlet 152a is located at the rear of the second cavity 220.

[0103] The rear of the second cavity 220 is the side of the second cavity 220 farthest from the access opening 230, and in the process of sending air to the second cavity 220, the user opens the door body 500 of the refrigeration equipment 10 to take and place items through the access opening 230, which is easy to cause the cold air flowing in the interior of the second cavity 220 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 lengthened, so as to 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 cavity 220.

[0104] Please refer to Figure 1 And Figure 3In 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 housing 120 and close to the rear of the housing 120, so that the air blown out of the second air outlet 123 flows to the third air outlet 152a through the shortest path.

[0105] Referring 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 flow in the second chamber 220, thereby improving the freezing effect inside the second chamber 220.

[0106] Referring 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 of 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 of the third air outlet 152a is small, so that the flow of the cold air blown out of 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 of the third air outlet 152a flows more uniformly in the width direction of the second chamber 220, thereby reducing the temperature difference at each position inside the second chamber 220 as much as possible, and reducing the problem of uneven refrigeration or freezing of food caused by temperature difference.

[0107] Referring 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, and the connecting piece 151 is in communication with 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 housing 120 along the width direction X of the housing 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 chamber 220 to minimize the impact of the connecting piece 151 on the capacity of the second chamber 220.

[0108] 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 second air outlet member 152 is spaced apart from 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 member 152, 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 of the shell 120 are frozen.

[0109] 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, and the second air outlet member 152 can blow air to the second chamber 220 through the third air outlet 152a 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 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 blowing and the uniformity of cold air inside the second chamber 220 can be increased as much as possible under the premise of reducing the number of parts inside the second chamber 220 and reducing the number of openings of the second chamber 220.

[0110] Please refer to Figure 1 and Figure 3 In some embodiments, the second air outlet member 150 is arranged at the rear of the second chamber 220, which reduces the occupation of the second air outlet member 150 to the space inside the second chamber 220, so that the second chamber 220 can accommodate as many items as possible, and the capacity of the second chamber 220 is improved.

[0111] The rear of the second chamber 220 is the side of the second chamber 220 away from the access opening 230, and in the process of blowing air to the second chamber 220, the user opens the door body 500 of the refrigeration equipment 10 to take and place items through the access opening 230, which is easy to cause the cold air flowing inside the second chamber 220 to overflow from the access opening 230. Arranging the second air outlet member 150 at the rear of the second chamber 220 can prolong the path of the cold air blown out by the second air outlet member 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.

[0112] Please refer to Figure 1 and Figure 3In some embodiments, the second air outlet component 150 is arranged on the top of the second chamber 220. Since there is less possibility of placing articles on the top of the second chamber 220, the cold air is less resistant, so that the flow of the cold air on the top of the second chamber 220 is large, thereby making the cold air blown from the second air outlet component 150 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. In addition, it is difficult for articles to accumulate on 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.

[0113] Referring to Figure 1 and Figure 3 In some embodiments, the second air outlet component 150 is arranged on the top and rear of the second chamber 220, and the access opening 230 is arranged on the front of the cabinet, which can minimize the influence of the second air outlet component 150 on the user's taking and placing of articles; the second air outlet component 150 of the second air outlet component 150 is in communication with the second air supply opening 123 arranged on 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.

[0114] Referring to Figure 7 and Figure 8 In some embodiments, the second air outlet component 152 is fixedly connected with at least one of the top wall and the rear wall of the second chamber 220, so that the second air outlet component 152 is fixed in the second chamber 220 and arranged on the top and rear of the second chamber 220; the second air outlet component 152 has a first fixed part 152b and a second fixed part 152c; the first fixed part 152b extends outward from the edge of the top of the first air outlet component 143 and abuts against the top wall of the second chamber 220, and the first fixed part 152b and the top wall of the first chamber 210 can be connected by screwing or buckling; the second fixed part 152c extends outward from the edge of the top of the first air outlet component 143 and abuts against the rear wall of the second chamber 220, and the second fixed part 152c and the rear wall of the first chamber 210 can be connected by screwing or buckling.

[0115] 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 through the first air vent 131a, the first air supply opening 122 and the second air outlet 143b of the first air outlet component 140, and the second air outlet 143b is arranged on 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 that the path of the cold air flowing to the first chamber 210 is minimized, thereby improving the air outlet efficiency.

[0116] 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.

[0117] 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.

[0118] 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 wind to the second air vent 131b, so that the wind 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 wind to flow to the second air vent 131b.

[0119] 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.

[0120] 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, maintain the air duct structure 100 in a closed state, and 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.

[0121] 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.

[0122] In some embodiments, the volute 131 is provided with a plurality of different air vents. The volute 131 supplies air to the first chamber 210 and the second chamber 220 through the plurality of different air vents, so as to control the air supply state of different chambers.

[0123] The plurality of air vents can be different in position or different in air outlet direction, so that the air duct structure 100 can blow cold air to different areas of the first chamber 210 or the second chamber 220 through different air vents, improve the uniformity of cold air in the first chamber 210 or the second chamber 220, and improve the refrigeration effect.

[0124] In some embodiments, the second air vent 131b is a plurality of second air vents 131b, and each second air vent 131b is in one-to-one communication with the 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.
