[0045] 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 a compressor, a condenser, a capillary, an evaporator and the like. Through the continuous circulation of the refrigerant, the heat inside the freezer is taken out of the freezer to achieve the purpose of cooling.

[0046] The air duct structure is used to supply air to the chamber. In the related art, the air duct structure includes an air duct, a volute and a fan assembly installed on the volute, and the air duct is communicated with the volute and the chamber. Under the driving of the fan assembly, the cold air is blown to the chamber through the air duct. However, the excessively long air duct causes the path of the air flow to be excessively long, which affects the low air supply efficiency. The volute in the related art is provided with only one air vent, and the air vent is communicated with the chamber through the air duct. The single air vent causes the air supply efficiency to be poor, which affects the freezing effect of the refrigeration equipment.

[0047] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0048] Please refer to Figure 1 and Figure 3 , the air duct structure provided in the embodiments of the present application is mainly applied to the refrigeration equipment 10, and the air duct structure 100 provided in the embodiments of the present application is used to supply air to the refrigeration equipment 10. The refrigeration equipment 10 is internally provided with a plurality of chambers, such as a first chamber 210 and a second chamber 220. The air duct structure 100 provided in the embodiments of the present application enables the cold air to flow in the first chamber 210 and the second chamber 220 in the refrigeration equipment 10, so as to achieve the freezing effect.

[0049] Among them, the refrigeration equipment 10 can be a refrigerator or a freezer. In the embodiments of the present application, the refrigeration equipment 10 is taken as an example for description for the convenience, and the same can be applied by analogy when the refrigeration equipment 10 is other equipment.

[0050] 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, respectively. Among them, 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.

[0051] 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 cabinet is the front, and the opposite side is the back.

[0052] Please refer to Figure 1 , Figure 3 andFigure 7 In the embodiment of the present application, the air duct structure 100 comprises a shell 120 and a fan assembly 130, the shell 120 has a mounting cavity 121, and the fan assembly 130 is arranged in the mounting cavity 121. The fan assembly 130 further comprises a volute 131 and a fan 132 arranged in the volute 131. The volute has a plurality of different air vents for air supply to at least one of the first chamber and the second chamber.

[0053] By arranging a plurality of air vents 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 cold air to at least one of the first chamber 210 and the second chamber 220 through the air vents. The volute 131 supplies air to the first chamber 210 and the second chamber 220 through a plurality of different air vents, so as to control the air supply state of different chambers.

[0054] 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.

[0055] 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.

[0056] In some embodiments, the mounting cavity 121 has a mounting top wall 121a and a mounting side wall 121b. The mounting top wall 121a has a first air supply port 122 for air supply to the first chamber 210, and the mounting side wall 121b has a second air supply port 123 for air supply to the second chamber 220. The fan assembly 130 can make the air in the mounting cavity 121 blow to the first chamber 210 through the first air supply port 122 and blow to the second chamber 220 through the second air supply port 123.

[0057] The air duct structure 100 is applied to the refrigeration equipment 10 and is installed in the cabinet of the refrigeration equipment 10. The air duct structure 100 can make the air in the refrigeration equipment 10 flow and blow to the refrigerated 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.

[0058] Since the thickness of the air duct structure 100 is smaller than the width, the width of the air duct structure 100 is substantially equal to the thickness of the refrigeration equipment 10. The air duct structure 100 can be installed on one side of the refrigeration equipment 10 in the width direction X, so that the air blown 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 can be improved as much as possible.

[0059] 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.

[0060] Among them, 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.

[0061] The shell 120 is the basic component of the air duct structure 100, which can provide a mounting basis 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, facilitating 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, reducing damage to the fan assembly 130 and other structures from external 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 air flow, so that the air in the installation cavity 121 is blown to the first chamber 210 through the first air supply port 122 and to the second chamber 220 through the second air supply port 123.

[0064] The first air outlet 122 is located on the top wall of the installation cavity 121, and cold air flows to the outside of the installation cavity 121 through the first air outlet 122, and then blows to the first chamber 210, so as to avoid that the installation cavity 121 is directly communicated with the first chamber 210, and the influence of the temperature of the installation cavity 121 on the first chamber 210 is reduced; the first air outlet 122 on the installation top wall 121a blows air to the first chamber 210, so as to avoid that a hole is opened between the first chamber 210 and the installation cavity 121, and the temperature of the first chamber 210 is beneficial to be maintained; the second air outlet 123 is located on the side wall of the installation cavity 121, and the second air outlet 123 can directly send cold air to the second chamber 220 through the second air outlet 123 on the installation side wall 121b, so as to reduce the flow path of the cold air and increase the air outlet efficiency; 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, and the cold air in the installation cavity 121 flows in different directions, so as to reduce the air flow between the first chamber 210 and the second chamber 220, to isolate the first chamber 210 and the second chamber 220 as much as possible, to reduce the heat transfer between the first chamber 210 and the second chamber 220, and to be beneficial to maintain the temperature difference between the first chamber 210 and the second chamber 220.

[0065] The air duct structure 100 can send 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 a set temperature, the air duct structure 100 stops sending air to the second chamber 220, and continues to send 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 installation cavity 121 and the second air outlet 123 is located on the side wall of the installation cavity 121, in the case that the air duct structure 100 stops sending 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 in a set temperature range. Of course, the air duct structure 100 can also send hot air to the first chamber 210 and the second chamber 220, and the embodiments of the present application do not particularly limit this.

[0066] The air duct structure 100 can be installed in the refrigeration equipment 10, the first chamber 210 can be a freezing chamber of the refrigeration equipment 10, and the second chamber 220 can be a variable-temperature chamber of the refrigeration equipment 10; the temperature of the variable-temperature chamber can be adjusted, which is suitable for storing different types of storage requirements, and the variable-temperature interval of the variable-temperature chamber is-3-5℃. Generally, the temperature of the freezing chamber is lower than that of the variable-temperature chamber. The air duct structure 100 is arranged between the freezing chamber and the variable-temperature chamber to isolate the freezing chamber and the variable-temperature chamber.

[0067] Please refer to Figure 1 andFigure 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 supply port 122 and the first chamber 210 and is configured to supply air to the first chamber 210.

[0068] The first air outlet component 140 can be used to supply air to the first chamber 210, and the air supply port does not need to be opened on the side wall of the installation cavity 121 facing the second chamber 220. In the case where the air duct structure 100 stops supplying air to the second chamber 220, the influence of the air duct structure 100 on the second chamber 220 can be reduced, and the temperature of the second chamber 220 can be maintained. The first air outlet component 140 supplies air to the first chamber 210, so that the air inlet path of the first chamber 210 is single-controllable, and the temperature of the first chamber 210 can be controlled conveniently.

[0069] The first air outlet component 140 is located outside the installation cavity 121, so as to avoid occupying the space of the installation cavity 121. The first air outlet component 140 can reduce the direct connection between the second chamber 220 and the air duct structure 100, and improve the heat insulation effect of the second chamber 220 without supplying air to the second chamber 220.

[0070] Please refer to Figure 4 In some embodiments, the first air outlet component 140 has a ventilation cavity 141, a first air outlet 143a and a second air outlet 143b. The first air outlet 143a is located at the top of the first chamber 210, and the second air outlet 143b is located at the rear of the first chamber 210. The ventilation cavity 141 can allow air blown out from the first air supply port 122 to enter the first chamber 210 through at least one of the first air outlet 143a and the second air outlet 143b.

[0071] The first air outlet 143a and the second air outlet 143b can be used to supply air to the first chamber 210, and the efficiency of supplying air to the first chamber 210 can be improved. The first air outlet 143a is located at the top of the first chamber 210, and the second air outlet 143b is located at the rear of the first chamber 210. Air can be supplied to the first chamber 210 from multiple directions, so that the airflow in the first chamber 210 flows more uniformly, the temperature difference between different positions in the first chamber 210 is reduced, and the problem of uneven refrigeration or freezing of food caused by temperature difference is reduced.

[0072] The box 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 the articles can be taken out of the first chamber 210 or the second chamber 220 or placed in the first chamber 210 or the second chamber 220 to be stored. The taking and placing opening 230 is located at the front of the box, and the door body 500 of the refrigeration device 10 covers the taking and placing opening 230. When the user takes or places the articles through the taking and placing opening 230, cold air can 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 flow first passes through the ventilation cavity 141, and then enters the first chamber 210 through at least one of the first air outlet 143a and the second air outlet 143b. The temperature difference of the air flowing through the first air outlet 143a and the second air outlet 143b is reduced as much as possible, the uniformity of the cold air in the first chamber 210 is improved, and the refrigeration effect is improved.

[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 1 In 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 as to intake air at different height positions in the first chamber 210, so that the cold air can be blown to different regions of the first chamber 210 more uniformly, and the refrigeration effect is better.

[0077] The first air return opening 124 is close to the bottom of the first chamber 210, so that the cold air can form a plurality of different circulation areas, improving the refrigeration effect. Specifically, during the process of placing the articles, the user basically stacks from bottom to top, and the lower articles are more, and the cold quantity required is also more. The second air outlet 143b is arranged between the first air outlet 143a and the first air return opening 124, so that the cold air can be blown out from the middle area of the cabinet, and can be blown to the bottom area 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 areas in the first chamber 210 more uniformly, 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 of the first air outlet 143a is uniformly distributed in the width direction of the first chamber 210, improving the uniformity of the temperature inside the first chamber 210, thereby improving the freezing effect; the first air outlet 143a is located at the top of the first chamber 210, and the probability of the articles being stacked to the top of the first chamber 210 is small, so that 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, and the temperature difference between each position inside the first chamber 210 is reduced as much as possible, reducing 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 chamber 210, so that the cold air of the second air outlet 143b is uniformly distributed in the width direction of the first chamber 210, improving the uniformity of the temperature inside the first chamber 210, thereby improving the freezing effect; the second air outlet 143b is located at the rear of the first chamber 210, so that the cold air blown out by the second air outlet 143b flows from the rear to the front of the first chamber 210; the length direction of the second air outlet 143b is arranged along the width direction of the first chamber 210, so that the cold air blown out by the first air outlet 143a flows more uniformly in the width direction of the first chamber 210, and the range of the cold air blown out by the first air outlet 143a in the width direction of the first chamber 210 is large, so as to reduce the temperature difference between 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 first air outlet 143a can be arranged along the width direction of the first chamber 210, or the length direction of the second air outlet 143b can be arranged along the width direction of the first chamber 210; in the embodiment of the present application, the length directions of the first air outlet 143a and the second air outlet 143b are both arranged along the width direction of the first chamber 210, so as to make the cold air act on each area in the first chamber 210 as much as possible.

[0082] In some embodiments, the first air outlet component 140 and the rear wall of the first chamber 210 form a fourth air outlet 143d, which faces the bottom of the first chamber 210, so that the cold air can blow to the bottom of the first chamber 210, thereby cooling the food at the bottom of the first chamber 210; the fourth air outlet 143d can increase the flow direction of the cold air in the first chamber 210, so that the distribution of the cold air in the first chamber 210 is more uniform, and the temperature difference of each part in the first chamber 210 is reduced.

[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 inlet 122 at the top of the mounting cavity 121 to the first chamber 210 through the body piece 142, so as to realize the air sending of the first chamber 210.

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

[0086] By sending 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, by arranging multiple first air outlets 143a or second air outlets 143b on the first air outlet 143, the air supply efficiency can be improved, the number of openings on the inner wall of the first chamber 210 can be reduced, and the heat insulation effect of the first chamber 210 can be improved, which is beneficial to maintaining the temperature of the first chamber 210.

[0087] The ventilation cavity 141 is at least partially located in the body member 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 member 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 member 142, or a part of the ventilation cavity 141 is arranged in the body member 142 and the other part is arranged in the first air outlet 143, as long as the body member 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 member 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 sends 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 143 sends 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 section 144 can be provided with the first air outlet 143a, the second air outlet section 145 is located at the rear of the first chamber 210, and the second air outlet section 145 can be provided with the second air outlet 143b, so that air is sent to the first chamber 210 from multiple directions, the airflow in the first chamber 210 is more uniform, the temperature difference between different positions in the first chamber 210 is reduced, and the problem of uneven refrigeration or freezing of food caused by 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 143, and the relative position relationship between the first air outlet 143 and the second air outlet 152 does not need to be adjusted during installation, which facilitates installation; the cold air in the body 142 passes through the first air outlet section 144, and 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 142, partially located in the first air outlet section 144, and partially located in the second air outlet section 145, so that the cold air passing through the ventilation cavity 141 can make the cold air blown out of the first air outlet 122 enter the first chamber 210 through at least one of the first air outlet 143a and the second air outlet 143b.

[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, so that the first chamber 210 can be blown from different directions through only one first air outlet 143, the number of components inside the first chamber 210 can be minimized, and the integration of the air duct structure 100 can be improved; the first chamber 210 only needs to be opened to connect the first air outlet part 140, which can reduce the number of openings on 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 occupation of the first air outlet 143 to the space inside the first chamber 210, so that the first chamber 210 can accommodate as many articles as possible, and the capacity of the first chamber 210 can be improved.

[0092] Please refer to Figure 4 to Figure 6 In some embodiments, one of the first air outlet 143 and the body 142 is provided with a clamping groove 142a, and the other is provided with a clamping protrusion 143c, and the clamping protrusion 143c cooperates with the clamping groove 142a.

[0093] Through the cooperation of the clamping protrusion 143c and the clamping groove 142a, the first air outlet 143 and the body 142 are connected; only by simply aligning and pressing or buckling the first air outlet 143 and the body 142, the connection between the two can be completed, the installation process is simplified, the connection between the first air outlet 143 and the body 142 is more simple and reliable, and the stability of the structure is improved.

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

[0095] Specifically, in the process of cooperation, the elastic piece 142d is moved 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 loosened, the elastic piece 142d is restored, and the first buckle is buckled in the first groove. The buckle block can be arranged at the end of the elastic piece 142d, which facilitates manual movement of the elastic piece 142d.

[0096] Referring 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 a hole between the mounting cavity 121 and the first chamber 210, so that the first chamber 210 is independent of the mounting cavity 121, and the mounting cavity 121 and the first chamber 210 are not directly communicated, thereby reducing 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 occupation of the space in the first chamber 210 by the body piece 142 can be reduced, and the capacity of the first chamber 210 can be increased as much as possible to store more articles.

[0097] Referring to Figure 2 and Figure 3 In some embodiments, the second air outlet 123 is a plurality of second air outlets 123, and at least two second air outlets 123 are arranged at intervals along the height direction Z of the shell 120, so that the cold air blown out by the second air outlet 123 can blow to different height positions of the second chamber 220, so that the cold air flows in different heights of the second chamber 220, and covers as much as possible the areas at different heights of the second chamber 220, thereby improving the uniformity of the cold air in the second chamber 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.

[0098] Referring to Figure 1 and Figure 3 In some embodiments, the air duct structure 100 further comprises a second air outlet component 150, and the second air outlet component 150 has a third air outlet 152a, the third air outlet 152a is communicated with the second air outlet 123, and the third air outlet 152a is arranged at intervals with the shell 120 along the width direction X of the shell 120.

[0099] The second air outlet component 150 sends the air from the second air supply opening 123 to the second chamber 220 through the third air outlet 152a, so as to blow the cold air to each area of the second chamber 220 as much as possible. Since the second air supply opening 123 is located on the sidewall of the shell 120, and the air duct structure 100 is located on one sidewall of the second chamber 220, the opposite sidewall is farthest from the air duct structure 100, so that the frozen items near the opposite sidewall receive the least cold air. In the width direction X of the shell 120, the third air outlet 152a is spaced apart from 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 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.

[0100] Referring to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is located on the top of the shell 120. Since there is less possibility of placing items on the top of the second chamber 220, the cold air receives less resistance, so that the flow of the cold air on the top of the second chamber 220 is large, thereby enabling the cold air blown from the third air outlet 152a to blow to the other side of the width direction X of the second chamber 220 as much as possible, so that the area farthest from the air duct structure 100 can be blown by the cold air.

[0101] Referring to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is located on the rear of the second chamber 220.

[0102] The rear of the second chamber 220 is the side of the second chamber 220 farthest from the access opening 230. In the process of sending air to the second chamber 220, the user opens the door 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 chamber 220 to overflow from the access opening 230. By arranging the third air outlet 152a on the rear of the second chamber 220, the path of the cold air blown from 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 chamber 220.

[0103] Referring to Figure 1 and Figure 3 In some embodiments, the third air outlet 152a is located on the top of the second chamber 220 and on the rear of the second chamber 220. The third air outlet 152a of the second air outlet component 150 is in communication with the second air supply opening 123 located 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 third air outlet 152a through the shortest path.

[0104] Referring toFigure 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 cavity 220, improving the uniformity of the cold air flow in the second cavity 220, thereby achieving better freezing effect inside the second cavity 220.

[0105] 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 cavity 220, so that the cold air of the third air outlet 152a is uniformly distributed in the width direction of the second cavity 220, improving the uniformity of the temperature inside the second cavity 220, thereby improving the freezing effect; the third air outlet 152a is located at the top of the second cavity 220, and the probability of the accumulation of goods to the top of the second cavity 220 is small, and the resistance of the cold air blown by the third air outlet 152a is small, so that the flow of the cold air blown by the third air outlet 152a is better; the length direction of the third air outlet 152a is arranged along the width direction of the second cavity 220, so that the cold air blown by the third air outlet 152a flows more uniformly in the width direction of the second cavity 220, thereby reducing the temperature difference at each position inside the second cavity 220 as much as possible, and reducing the problem of uneven refrigeration or freezing of food caused by temperature difference.

[0106] Please refer to Figure 1 And Figure 3 In some embodiments, the second air outlet component 150 includes a connecting piece 151 and a second air outlet piece 152, the connecting piece 151 communicates the second air 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 much as possible to be attached 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.

[0107] 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 goods near the opposite side wall receive the least cold air; along the width direction X of the shell 120, the second air outlet piece 152 is arranged spaced apart from the shell 120, and the cold air is blown as much as possible to the side of the shell 120 away from the air duct structure 100 through the second air outlet piece 152, so that the cold air flows to the farthest position as much as possible, thereby freezing the frozen goods far away from the air duct structure 100 of the shell 120.

[0108] The second air outlet member 152 can extend in the width direction X of the shell 120, and the second air outlet member 152 is provided with a third air outlet 152a through which the second air outlet member 152 can send cold air to the second chamber 220 to blow the cold air to a position as far as possible from the air duct structure 100; in order to improve the air sending efficiency of the second air outlet member 152, a plurality of third air outlets 152a can be provided on the second air outlet member 152, and by providing a plurality of third air outlets 152a on the second air outlet member 152, the efficiency of air sending and the uniformity of cold air inside the second chamber 220 can be as high as possible under the premise of reducing the number of parts in the second chamber 220 and reducing the number of openings of the second chamber 220.

[0109] Referring 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 in the space inside the second chamber 220, so that the second chamber 220 can accommodate as many articles as possible, thereby improving the capacity of the second chamber 220.

[0110] 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 sending cold air to the second chamber 220, the user opens the door 500 of the refrigeration equipment 10 to take and place articles through the access opening 230, which is easy to cause the cold air flowing inside the second 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 by the second air outlet member 150 to the access opening 230, thereby reducing 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.

[0111] Referring to Figure 1 and Figure 3 In some embodiments, the second air outlet member 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 receives small resistance, so that the flowability of the cold air at the top of the second chamber 220 is large, thereby making the cold air blown from the second air outlet member 150 blow to the other side of the width direction X of the second 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 at the top of the second chamber 220, and the above arrangement can reduce the influence of the second air outlet member 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.

[0112] Referring to Figure 1 and Figure 3In some embodiments, the second air outlet component 150 is located at the top of the second chamber 220 and at the rear of the second chamber 220, and the access opening 230 is located at the front of the cabinet, so that the influence of the second air outlet component 150 on the user's taking and placing of articles can be minimized; the second air outlet component 150 of the second air outlet component 150 is in communication with the second air supply opening 123 located at the top of the shell 120 and close to the rear of the shell 120, so that the air blown out of the second air supply opening 123 flows to the second air outlet component 150 through the shortest path.

[0113] Please refer to Figure 7 and Figure 8 In some embodiments, the second air outlet component 150 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 150 is fixed in the second chamber 220 and located at the top and the rear of the second chamber 220; the second air outlet component 150 has a first fixed portion 152b and a second fixed portion 152c; the first fixed portion 152b extends outwardly 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 portion 152b and the top wall of the first chamber 210 can be connected in a fixed manner such as by screws or buckles; the second fixed portion 152c extends outwardly 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 portion 152c and the rear wall of the first chamber 210 can be connected in a fixed manner such as by screws or buckles.

[0114] The air vent includes a first air vent 131a located at the top of the volute 131, and the first air vent 131a is used to supply air to the first chamber 210; the cold air can flow out of the top of the volute 131 to supply air to the first chamber 210, which can avoid opening a hole between the first chamber and the mounting cavity 121 and reduce the influence of the temperature of the mounting cavity 121 on the first chamber 210; in addition, the above arrangement is conducive to the communication of the first air vent 131a with the first air supply opening 122, which reduces the path between the first air vent 131a and the first air supply opening 122, thereby reducing air loss and improving air outlet efficiency.

[0115] Please refer 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 blows towards 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 located at the rear wall of the first chamber 210; the arrangement of the first air vent 131a close to the rear wall of the first chamber 210 minimizes the path of the cold air flowing to the first chamber 210, thereby improving 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 first air outlet component 140 and the first air outlet component 140. The sealing member 163 can effectively prevent cold air leakage, maintain the air duct structure 100 airtight, and prevent external dust and impurities from entering through the joint between the first air outlet component 140 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 air vent includes a second air vent 131b arranged on the side wall of the volute 131, which is beneficial to shorten the distance between the second air vent 131b and the second chamber 220 and improve the air supply efficiency. The second air vent 131b 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. Arranging the second air vent 131b on the side wall of the volute 131 can shorten the path between the second air vent 131b and the second air outlet 123, reduce energy loss, and accelerate the air supply efficiency.

[0122] In some embodiments, the second air vent 131b is a plurality of second air vents 131b, and the 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 in the height direction Z of the shell 120. At least two second air outlets 123 are arranged in the height direction Z of the shell 120 to reduce the path between the second air outlet 123 and the second air vent 131b as much as possible, reduce the air duct, and thus reduce the air loss and improve the air supply efficiency.
