Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a freezer. Background Technology

[0002] A freezer is a device used to preserve food and other items at low temperatures. A freezer typically includes a cabinet with a refrigeration compartment, a door for opening or closing the refrigeration compartment, and an air duct assembly for supplying cold air to the refrigeration compartment.

[0003] In related technologies, the air duct assembly is housed within a cabinet, dividing the cabinet into a cooling compartment and an evaporator compartment, with the evaporator located within the evaporator compartment. The air duct assembly consists of a front cover and a rear cover, which enclose an air cavity. The front cover faces the cooling compartment and has an air outlet that communicates with the cooling compartment. The rear cover faces the evaporator compartment and has an air inlet that communicates with the evaporator compartment. A fan is located within the air cavity. When the fan rotates, cold air from the evaporator compartment enters the air cavity through the air inlet and is then transported to the cooling compartment through the air outlet to lower the temperature within the cooling compartment.

[0004] However, the relevant freezers have the problem of large temperature differences within the refrigeration compartment. Utility Model Content

[0005] This application provides a freezer that can solve the technical problem of large temperature differences in the refrigeration compartment of related freezers.

[0006] This application provides a freezer, including:

[0007] The inner liner has a structure that forms a gallbladder cavity;

[0008] An air duct assembly, disposed within the duct cavity, defines an air cavity; the air duct assembly includes:

[0009] The front cover of the air duct, together with the inner liner, forms a refrigeration compartment. The front cover of the air duct has an air outlet, which is connected to the air cavity and the refrigeration compartment respectively.

[0010] The air guide rib component is set in the air cavity. The air guide rib component is constructed with a first air outlet channel and a second air outlet channel. The first air outlet channel and the second air outlet channel are arranged sequentially along the extension direction of the air outlet. The air outlet ends of the first air outlet channel and the second air outlet channel both face the air outlet, and the air outlet directions of the first air outlet channel and the second air outlet channel are opposite to each other.

[0011] The air guide plate is located on the side of the air guide rib component closer to the refrigeration room and at the air outlet. The air guide plate is rotatably connected to the front cover of the air duct.

[0012] In the refrigerator of this embodiment, the first and second air outlet channels of the air guide rib component have opposite air outlet directions, increasing the lateral coverage of the air blown by the air guide rib component, thereby reducing the temperature difference in the refrigeration compartment along the width direction of the front cover plate of the air duct. The air guide plate rotates relative to the front cover plate of the air duct to deliver the air blown by the air guide rib component to different height areas of the refrigeration compartment, reducing the temperature difference in the height direction of the refrigeration compartment. Through the cooperation of the air guide rib component and the air guide plate, the temperature difference in the refrigeration compartment along both the width direction and the height direction of the air duct is reduced, thus reducing the temperature difference at different locations within the refrigeration compartment and improving the low-temperature preservation effect of the items.

[0013] In some embodiments of this application, the air guide rib component includes:

[0014] The frame is connected to the front cover of the air duct, and the frame forms an air outlet duct, which is opposite to the air outlet. The frame includes a first frame sidewall and a second frame sidewall that are arranged opposite to each other along the extension direction of the air outlet.

[0015] The first stiffener is located inside the air outlet duct and is set close to the side wall of the first frame. In the extension direction of the air guide plate, the distance between the first stiffener and the side wall of the first frame decreases from the end away from the air outlet to the end close to the air outlet. The first stiffener forms a first air outlet channel on both sides along the extension direction of the air outlet.

[0016] The second stiffener is located inside the air outlet duct and is set close to the side wall of the second frame. In the extension direction of the air guide plate, the distance between the second stiffener and the side wall of the second frame decreases from the end away from the air outlet to the end closer to the air outlet. The second stiffener forms a second air outlet channel on both sides along the extension direction of the air outlet.

[0017] With this configuration, the cold air in the air cavity flows to the end of the first air outlet channel away from the air outlet, and under the guidance of the first stiffener, it is blown out along the inclined first stiffener in a direction away from the side wall of the second frame. The cold air in the air cavity flows to the end of the second air outlet channel away from the air outlet, and under the guidance of the second stiffener, it is blown out along the inclined second stiffener in a direction away from the side wall of the first frame.

[0018] In some embodiments of this application, the air guide rib component further includes a third rib plate, which is located in the air outlet duct and is spaced between the first rib plate and the second rib plate.

[0019] In the extending direction of the air guide plate, the distance between the third rib and the first rib increases from the end away from the air outlet to the end closer to the air outlet; and the distance between the third rib and the second rib increases from the end away from the air outlet to the end closer to the air outlet.

[0020] With this configuration, the cold air inside the air cavity flows to the end of the third air outlet duct opposite to the air outlet, and then, guided by the third rib, is blown out along the third rib to deliver air to the central area of ​​the cooling room. The central area of ​​the cooling room refers to the cooling room area corresponding to the middle of the direction in which the air outlet extends.

[0021] In some embodiments of this application, the air guide rib component further includes an upper wind deflector, which is located on the side of the frame facing the air outlet and is connected to the top of the frame.

[0022] With this design, the upper baffle can block the amount of air flowing back into the air cavity from the top of the gap between the frame and the front cover of the air duct, thereby increasing the amount of cold air blown out from the air outlet and improving the cooling effect on the cooling room.

[0023] In some embodiments of this application, the air guide rib component further includes a lower air baffle, which is located on the side of the frame facing the air outlet and is connected to the bottom of the frame.

[0024] With this design, the lower baffle can block the amount of air flowing back into the air cavity from the bottom of the gap between the frame and the front cover of the air duct, thereby increasing the amount of cold air blown out from the air outlet and improving the cooling effect on the cooling room.

[0025] In some embodiments of this application, the front cover of the air duct is constructed with two connecting holes arranged opposite to each other;

[0026] The air guide plate includes:

[0027] The plate extends in a direction parallel to the direction of the air outlet.

[0028] Two connecting shafts are respectively located at both ends of the plate's extension direction, and the two connecting shafts are rotatably inserted into their respective connecting holes.

[0029] With this configuration, the two connecting shafts are rotatably inserted into their respective connecting holes, allowing the air guide plate to be rotatably mounted on the front cover of the air duct.

[0030] In some embodiments of this application, the air duct assembly further includes a driving device connected to the front cover of the air duct, the driving device being connected to the air guide plate and driving the air guide plate to rotate.

[0031] This setup allows the air guide plate to rotate via a drive unit, saving time and effort.

[0032] In some embodiments of this application, the air outlet is located at the top of the front cover of the air duct.

[0033] With this configuration, the cold air blown from the air outlet into the cooling room can first cover the upper area of ​​the cooling room, and then, due to the high density of cold air, it diffuses downwards and covers the lower area of ​​the cooling room, thus increasing the area that the cold air blown from the air outlet can cover in the cooling room.

[0034] In some embodiments of this application, the air outlet extends along the width direction of the front cover of the air duct.

[0035] This design increases the lateral coverage of the cold air blowing from the air outlet into the cooling room, and reduces the temperature difference in the cooling room along the width of the front cover of the air duct.

[0036] In some embodiments of this application, the side of the air duct assembly away from the cooling chamber is enclosed with the inner liner to form a heat exchange chamber, and the heat exchange chamber is connected to the air cavity.

[0037] The freezer includes a refrigeration unit, which includes an evaporator, and the evaporator is located in a heat exchange chamber;

[0038] The front cover of the air duct is also equipped with a return air inlet, which is located below the air outlet and is connected to the heat exchange chamber.

[0039] With this configuration, the air in the cooling room flows to the heat exchange chamber through the return air vent. As it flows through the evaporator, its temperature decreases. The cold air in the heat exchange chamber then flows back into the cooling room through the air outlet. This cycle continues, allowing the air between the cooling room and the heat exchange chamber to circulate and continuously supply cold air to the cooling room, thus maintaining a low-temperature environment in the cooling room.

[0080] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0081] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0082] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0083] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0084] Regarding the issue of large temperature differences within the cooling compartments of freezers in related technologies, the inventors discovered that this is due to the following: The freezers utilize multiple sets of air outlets spaced along the vertical direction on the front cover of the air duct. These outlets at different heights blow cold air into the cooling compartments within different height ranges, thus reducing the temperature difference along the height of the cooling compartments. Each set of outlets includes multiple outlets arranged along the width of the front cover of the air duct, blowing cold air into cooling compartments at the same height but with different widths, further reducing the temperature difference along the width of the air duct. However, stacked items within the cooling compartment can easily block the lower outlets, while the cold air from the upper outlets is difficult to deliver to the bottom of the cooling compartment. This results in cold air failing to reach certain areas within the cooling compartment, leading to the problem of large temperature differences within the cooling compartment.

[0085] In view of this, this application provides a freezer with an air guide plate and an air guide rib component at the air outlet. The air guide plate is rotatably mounted at the air outlet, and the air guide rib component is located inside the air guide plate. The air outlet directions of the first and second air outlet channels of the air guide rib component are opposite, increasing the lateral coverage of the air blown by the air guide rib component, thereby reducing the temperature difference in the refrigeration compartment along the width direction of the front cover plate of the air duct. The air guide plate rotates relative to the front cover plate of the air duct to deliver the air blown by the air guide rib component to different height areas of the refrigeration compartment, reducing the temperature difference in the height direction of the refrigeration compartment. Through the cooperation of the air guide rib component and the air guide plate, both the temperature difference in the width direction of the refrigeration compartment along the front cover plate of the air duct and the temperature difference in the height direction of the refrigeration compartment are reduced, thus reducing the temperature difference at different locations within the refrigeration compartment and improving the low-temperature preservation effect of items.

[0086] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0087] refer to Figure 1 and Figure 2 The freezer provided in this embodiment may include a cabinet body 10, a door 20, a refrigeration unit 50, and an air duct assembly 30. The cabinet body 10 may have a refrigeration compartment 121. The door 20 is rotatably connected to the cabinet body 10 to open or close the refrigeration compartment 121. The refrigeration unit 50 is disposed inside the cabinet body 10 and is used to provide cold air to the refrigeration compartment 121. The air duct assembly 30 is disposed inside the cabinet body 10 and is used to transport the cold air provided by the refrigeration unit 50 to the refrigeration compartment 121 to reduce the temperature of the refrigeration compartment 121.

[0088] The refrigeration unit 50 can be installed inside the enclosure. The refrigeration unit 50 can be any refrigeration unit 50 in the related art. The refrigeration unit 50 is used to supply cold air to the refrigeration chamber 121 to reduce the temperature inside the refrigeration chamber 121.

[0089] refer to Figure 2 The refrigeration unit 50 may include a compressor 510, a condenser 520, a throttling element, and an evaporator 530. The compressor 510, condenser 520, throttling element, and evaporator 530 may be connected in series via pipes, through which refrigerant may flow. The throttling element may be a capillary tube or an electronic expansion valve, etc.

[0090] When the freezer cools the refrigeration compartment 121, the refrigerant circulates within the compressor 510, condenser 520, throttling element, and evaporator 530. As it flows through the evaporator 530, it absorbs heat and lowers the temperature of the evaporator 530 and the surrounding air. The air flowing through the evaporator 530 is then transported into the refrigeration compartment 121 to further reduce the temperature within it.

[0091] refer to Figure 2 The cabinet 10 may include an outer shell 110 and an inner liner 120. The outer shell 110 is attached to the outside of the inner liner 120 to form the appearance of the cabinet 10.

[0092] The inner liner 120 is constructed to form a cavity, and the refrigeration chamber 121 can occupy part of the space of the cavity. The top of the cavity can be formed with a retrieval port 123, which is connected to the refrigeration chamber 121. Items can be taken out from the refrigeration chamber 121 through the retrieval port 123, or items can be placed into the refrigeration chamber 121 through the retrieval port 123.

[0093] refer to Figure 2 A heat insulation cavity 130 can be formed between the outer shell 110 and the inner liner 120. The heat insulation cavity 130 can be filled with heat insulation material, such as foaming agent. The heat insulation material can reduce the heat exchange between the cooling chamber 121 and the outside of the outer shell 110, thereby achieving the heat preservation effect of the cooling chamber 121.

[0094] The door 20 can be rotatably connected to the outer shell 110. The outer shell 110 has high structural strength. The rotatable connection between the door 20 and the outer shell 110 can improve the reliability of the connection between the door 20 and the cabinet 10.

[0095] Door 20 can open and close the pick-up and drop-off ports 123.

[0096] When the door 20 opens the access port 123, items can be taken from or placed into the refrigeration room 121 through the access port 123.

[0097] When door 20 closes access ports 123 (for reference) Figure 1 The door 20 reduces the leakage of cold air from the refrigeration compartment 121 through the access port 123, thereby improving the refrigeration effect of the freezer on the items in the refrigeration compartment 121.

[0098] refer to Figure 2 The air duct assembly 30 is disposed inside the duct cavity and divides the duct cavity into a cooling chamber 121 and a heat exchange chamber 122. That is to say, the cooling chamber 121 and the heat exchange chamber 122 are located on both sides of the air duct assembly 30.

[0099] refer to Figure 2 The air duct assembly 30 is constructed to form an air cavity 301. (Reference) Figure 2 , Figure 3 and Figure 4 The air duct assembly 30 may include a front cover plate 310 and a rear cover plate 320, which can be enclosed to form an air cavity 301.

[0100] The rear cover plate 320 of the air duct and the inner liner 120 enclose a heat exchange chamber 122. The evaporator 530 can be installed in the heat exchange chamber 122. When the refrigeration unit 50 is working, the temperature of the evaporator 530 and the heat exchange chamber 122 decreases.

[0101] refer to Figure 2 The rear cover plate 320 of the air duct can be configured with an air inlet 321, which is connected to the heat exchange chamber 122 and the air cavity 301 respectively. The cold air in the heat exchange chamber 122 can flow into the air cavity 301 through the air inlet 321.

[0102] refer to Figure 2 The front cover plate 310 of the air duct and the inner liner 120 enclose each other to form a cooling chamber 121. The front cover plate 310 of the air duct may be configured with an air outlet 311, which is connected to the air cavity 301 and the cooling chamber 121 respectively. The cold air in the air cavity 301 can flow into the cooling chamber 121 through the air outlet 311 to reduce the temperature in the cooling chamber 121.

[0103] refer to Figure 4 The air outlet 311 can extend along the width direction X of the front cover plate 310 of the air duct to increase the lateral coverage of the cold air blown from the air outlet 311 to the cooling room 121, thereby reducing the temperature difference in the cooling room 121 along the width direction X of the front cover plate 310 of the air duct.

[0104] In some possible implementations of the embodiments of this application, reference is made to Figure 4 The air duct assembly 30 may also include a seal 370, which is disposed between the front cover plate 310 and the rear cover plate 320 of the air duct. The seal 370 may be a foam component. The seal 370 can seal the gap at the periphery of the front cover plate 310 and the rear cover plate 320 of the air duct, thereby reducing the possibility of air leakage from the air cavity 301 through the gap between the front cover plate 310 and the rear cover plate 320 of the air duct.

[0105] In some possible implementations of the embodiments of this application, reference is made to Figure 2 , Figure 3 and Figure 4 The air outlet 311 can be located at the top of the front cover plate 310 of the air duct. The cold air blown from the air outlet 311 to the cooling room 121 can first cover the upper area of ​​the cooling room 121. Then, due to the high density of the cold air, it diffuses downward and covers the lower area of ​​the cooling room 121, thus increasing the area of ​​the cooling room 121 that can be covered by the cold air blown from the air outlet 311.

[0106] In some possible implementations of the embodiments of this application, reference is made to Figure 2 , Figure 3 and Figure 4 The front cover plate 310 of the air duct can also be configured with a return air inlet 312, which is located below the air outlet 311 and is connected to the heat exchange chamber 122.

[0107] Air in the refrigeration chamber 121 flows to the heat exchange chamber 122 through the return air vent 312. When it flows through the evaporator 530, the temperature decreases. The cold air in the heat exchange chamber 122 flows to the air cavity 301 through the air inlet 321. The cold air in the air cavity 301 then flows back into the refrigeration chamber 121 through the air outlet 311. This cycle is repeated to ensure that the air between the refrigeration chamber 121 and the heat exchange chamber 122 circulates, thereby continuously supplying cold air to the refrigeration chamber 121 and keeping the refrigeration chamber 121 in a low-temperature environment.

[0108] In some possible implementations of the embodiments of this application, reference is made to Figure 2 and Figure 4 The freezer may also include a fan 40. The fan 40 is disposed within the air cavity 301. The fan 40 may be connected to the air duct assembly 30. The fan 40 may be connected to the front cover plate 310 or the rear cover plate 320 of the air duct.

[0109] The fan 40 may include a bracket, which can be connected to the front cover plate 310 of the air duct.

[0110] The fan 40 may also include a motor and an impeller. The motor is connected to a bracket. The impeller is located on the side of the bracket opposite to the front cover plate 310 of the air duct. The impeller is driven by the motor and rotates around its own axis under the drive of the motor.

[0111] One end of the impeller axis has an air inlet, which is positioned opposite to the air inlet 321, or in other words, the air inlet faces the air inlet 321.

[0112] The impeller has an air outlet on its outer circumference. The air outlet is connected to the air chamber 301.

[0113] When the impeller rotates, it generates centrifugal force, which draws in the gas at the inlet, pressurizes and accelerates it, and then discharges it from the outlet. The air in the heat exchange chamber 122 flows from the air inlet 321 to the air outlet, and after being pressurized and accelerated by the impeller, it flows from the outlet into the air cavity 301.

[0114] The end of the impeller away from the front cover plate 310 of the air duct is spaced apart from the rear cover plate 320 of the air duct. In other words, there is a gap between the end of the impeller away from the front cover plate 310 of the air duct and the rear cover plate 320 of the air duct, so that the impeller is less likely to rub against the rear cover plate 320 of the air duct when it rotates, and the impeller and the rear cover plate 320 of the air duct are less likely to wear and generate friction noise.

[0115] The fan 40 can increase the air velocity in the heat exchange chamber 122 and the cooling chamber 121, thereby improving the cooling efficiency of the cooling chamber 121.

[0116] In some possible implementations of the embodiments of this application, reference is made to Figures 2-5 The air duct assembly 30 may also include an air guide rib member 330. The air guide rib member 330 is disposed within the air cavity 301. The air guide rib member 330 may be connected to the front cover plate 310 or the rear cover plate 320 of the air duct.

[0117] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 The air guide rib component 330 can be constructed with a first air outlet channel 3301 and a second air outlet channel 3302. The first air outlet channel 3301 and the second air outlet channel 3302 are arranged sequentially along the extension direction of the air outlet 311. The air outlet ends of the first air outlet channel 3301 and the second air outlet channel 3302 both face the air outlet 311, and the air outlet directions of the first air outlet channel 3301 and the second air outlet channel 3302 are ( Figure 8 (As indicated by the red indicator line in the middle) diverges from each other.

[0118] The cold air in the air cavity 301 flows to the air outlet 311 through the first air outlet channel 3301 and the second air outlet channel 3302, and then flows into the cooling room 121 from the air outlet 311. Since the air outlet directions of the first air outlet channel 3301 and the second air outlet channel 3302 are opposite, the lateral coverage of the air blown by the air guide member 330 is increased, thereby further reducing the temperature difference in the cooling room 121 along the width direction X of the front cover plate 310 of the air duct.

[0119] The following is for reference Figure 6 , Figure 7 and Figure 8 The structure of the air guide rib component 330 is described.

[0120] The air guide rib component 330 may include a frame 331. The frame 331 forms an air outlet duct, which is opposite to the air outlet 311.

[0121] The frame 331 may include a first frame sidewall 3311 and a second frame sidewall 3312 disposed opposite to each other along the extension direction of the air outlet 311.

[0122] The frame 331 may also include a top wall 3313 and a bottom wall 3314 spaced apart along the height direction of the front cover plate 310 of the air duct. The top wall 3313 is located above the bottom wall 3314.

[0123] The top wall 3313, the first side wall 3311, the bottom wall 3314, and the second side wall 3312 are connected sequentially to form the frame 331.

[0124] The air guide rib component 330 may further include a first stiffener 332. The first stiffener 332 is located inside the air outlet duct and is disposed near the first frame sidewall 3311. In the width direction X of the air outlet front cover plate 310, the distance between the first stiffener 332 and the first frame sidewall 3311 decreases from the end away from the air outlet 311 to the end closer to the air outlet 311. That is, the first stiffener 332 is inclined towards the first frame sidewall 3311 from the end away from the air outlet 311 to the end closer to the air outlet 311. The first stiffener 332 forms first air outlet channels 3301 on both sides along the extension direction of the air outlet 311.

[0125] After the cold air in the air cavity 301 flows to the end of the first air outlet 3301 away from the air outlet 311, it is blown out along the inclined first stiffener 332 towards the direction away from the second frame side wall 3312 under the guidance of the first stiffener 332.

[0126] The air guide rib member 330 may further include a second stiffener 333. The second stiffener 333 is located inside the air outlet duct and is disposed near the second frame sidewall 3312. In the width direction X of the air outlet front cover plate 310, the distance between the second stiffener 333 and the second frame sidewall 3312 decreases from the end away from the air outlet 311 to the end closer to the air outlet 311. That is, the second stiffener 333 is inclined towards the second frame sidewall 3312 from the end away from the air outlet 311 to the end closer to the air outlet 311. The second stiffener 333 forms second air outlet channels 3302 on both sides along the extension direction of the air outlet 311.

[0127] After the cold air in the air cavity 301 flows to the end of the second air outlet 3302 away from the air outlet 311, it is blown out along the inclined second stiffener 333 in the direction away from the first frame side wall 3311 under the guidance of the second stiffener 333.

[0128] The cold air blown out by the first air outlet duct 3301 and the second air outlet duct 3302 flows in opposite directions, which increases the lateral coverage of the air blown out by the air guide rib member 330, thereby further reducing the temperature difference in the cooling room 121 along the width direction X of the front cover plate 310 of the air duct.

[0129] In some possible implementations of this application, the top of the first stiffener 332 and the top of the second stiffener 333 can be connected to the top wall 3313 of the frame, and the bottom of the first stiffener 332 and the bottom of the second stiffener 333 can be connected to the bottom wall 3314 of the frame. On the one hand, this can improve the reliability of the connection between the first stiffener 332, the second stiffener 333 and the frame 331; on the other hand, when cold air flows through the first stiffener 332 and the second stiffener 333, the swaying amplitude of the first stiffener 332 and the second stiffener 333 can be reduced, thereby reducing the noise of the freezer.

[0130] In some possible implementations of the embodiments of this application, the air guide rib member 330 may further include a third rib plate 334, which is located in the air outlet duct and is spaced between the first rib plate 332 and the second rib plate 333. The third rib plate 334 is connected to the frame 331.

[0131] The top of the third stiffener 334 can be connected to the top wall 3313 of the frame, and the bottom of the third stiffener 334 can be connected to the bottom wall 3314 of the frame. On the one hand, this can improve the reliability of the connection between the third stiffener 334 and the frame 331; on the other hand, when cold air flows through the third stiffener 334, the swing amplitude of the third stiffener 334 can be reduced, thereby reducing the noise of the freezer.

[0132] There can be multiple third stiffeners 334, which are arranged at intervals along the extension direction of the air outlet 311. A third air outlet channel 3303 is formed between two adjacent third stiffeners 334.

[0133] In the width direction X of the front cover plate 310 of the air duct, the distance between the third stiffener 334 and the first stiffener 332 increases from the end away from the air outlet 311 to the end closer to the air outlet 311; and the distance between the third stiffener 334 and the second stiffener 333 increases from the end away from the air outlet 311 to the end closer to the air outlet 311.

[0134] The cold air in the air cavity 301 flows to the end of the third air outlet duct 3303 opposite to the air outlet 311, and is then blown out along the third rib 334 under the guidance of the third rib 334. Since multiple third ribs 334 are located between the first rib 332 and the second rib 333, the cold air blown out from the third air outlet duct 3303 is concentrated between the first air outlet duct 3301 and the second air outlet duct 3302, so as to outlet air to the central area of ​​the cooling chamber 121. The central area of ​​the cooling chamber 121 refers to the area of ​​the cooling chamber 121 corresponding to the center of the direction of extension of the air outlet 311.

[0135] The cold air blown into the cooling room 121 by the first air outlet duct, the second air outlet duct 3302 and the third air outlet duct 3303 can cover the entire area of ​​the cooling room 121 along the width direction X of the front cover plate 310 of the air duct, which increases the lateral coverage of the air blown out by the air guide rib member 330, thereby reducing the temperature difference of the cooling room 121 along the width direction X of the front cover plate 310 of the air duct.

[0136] In some possible implementations of the embodiments of this application, the air guide rib component 330 may also include an upper wind deflector 335. The upper wind deflector 335 is located on the side of the frame 331 facing the air outlet 311, and the upper wind deflector 335 is connected to the top of the frame 331, that is, connected to the end of the frame top wall 3313 facing the air outlet 311.

[0137] The upper baffle 335 can block the amount of air flowing back into the air cavity 301 from the top of the gap between the frame 331 and the front cover plate 310 of the air duct, thereby increasing the amount of cold air blown out from the air outlet 311 and improving the cooling effect on the cooling chamber 121.

[0138] In some possible implementations of the embodiments of this application, the air guide rib member 330 may also include a lower baffle plate 336, which is located on the side of the frame 331 facing the air outlet 311 and is connected to the bottom of the frame 331.

[0139] The lower baffle 336 can block the amount of air flowing back into the air cavity 301 from the bottom of the gap between the frame 331 and the front cover plate 310 of the air duct, thereby increasing the amount of cold air blown out from the air outlet 311 and improving the cooling effect on the cooling chamber 121.

[0140] In some possible implementations of the embodiments of this application, reference is made to Figure 2 , Figure 3 , Figure 4 and Figure 5 The air duct assembly 30 may also include an air guide plate 340, which is located at the air outlet 311 and the extension direction of the air guide plate 340 may be consistent with the extension direction of the air outlet 311.

[0141] refer to Figure 2 and Figure 9 The air guide plate 340 is located on the side of the air guide rib member 330 that is close to the cooling room 121, that is, at the air outlet end of the air guide rib member 330, so that the cold air blown out by the air guide rib member 330 flows to the air guide plate 340, is guided by the air guide plate 340 and then blown into the cooling room 121.

[0142] The air guide plate 340 is rotatably connected to the front cover plate 310 of the air duct, and the rotation axis of the air guide plate 340 relative to the front cover plate 310 of the air duct can be along the extension direction of the air outlet 311.

[0143] When the air guide plate 340 rotates relative to the front cover plate 310 of the air duct, it can deliver the cold air blown out by the air guide rib member 330 to different height areas of the refrigeration chamber 121, thereby reducing the temperature difference in the height direction of the refrigeration chamber 121.

[0144] By combining the air guide rib component 330 and the air guide plate 340, the temperature difference in the width direction X of the refrigeration chamber 121 along the front cover plate 310 of the air duct is reduced, as is the temperature difference in the height direction of the refrigeration chamber 121. This reduces the temperature difference at different locations within the refrigeration chamber 121 and improves the low-temperature preservation effect of items within the refrigeration chamber 121.

[0145] In some possible implementations of the embodiments of this application, reference is made to Figure 10 The front cover plate 310 of the air duct can be constructed with two oppositely arranged connection holes 313.

[0146] refer to Figure 11 The air guide plate 340 may include a plate body 341 and two connecting shafts 342. The extending direction of the plate body 341 may be parallel to the extending direction of the air outlet 311. The two connecting shafts 342 may be respectively disposed at both ends of the extending direction of the plate body 341, and the two connecting shafts 342 are rotatably inserted into corresponding connecting holes 313, so as to rotatably mount the air guide plate 340 to the front cover plate 310 of the air duct.

[0147] In some possible implementations of the embodiments of this application, reference is made to Figure 9 , Figure 11 , Figure 12 , Figure 13 and Figure 14 The air duct assembly 30 may also include a drive unit 350, which is connected to the air duct front cover 310.

[0148] refer to Figure 9 , Figure 11 and Figure 14 The air duct assembly 30 may also include a mounting bracket 360. The drive unit 350 may be connected to the mounting bracket 360, which is connected to the air duct front cover plate 310 to indirectly connect the drive unit 350 to the air duct front cover plate 310.

[0149] The drive unit 350 is connected to the air guide plate 340 and drives the air guide plate 340 to rotate. The drive unit 350 drives the air guide plate 340 to rotate, which saves time and effort.

[0150] The drive unit 350 can be an electric motor or other device that can convert electrical energy into rotational mechanical energy.

[0151] The motor may include a motor body and an output shaft. The motor body is connected to the output shaft and drives the output shaft to rotate around its own axis. The output shaft may be connected to a connecting shaft 342 so that the connecting shaft 342 can be rotated through the output shaft, thereby causing the plate 341 to rotate around the connecting shaft 342.

[0152] Both connecting shafts 342 can be connected to motors to improve the synchronicity of the rotation of the two ends of the air guide plate 340 and reduce the possibility of jamming when the air guide plate 340 rotates.

[0153] In some other possible implementations of this application, the air guide plate 340 can be manually rotated according to the height of the stacked items in the refrigeration chamber 121 so that the cold air blown out from the air outlet 311 can be blown as far as possible towards the items in the refrigeration chamber 121.
