[0050] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure and its application or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein.

[0051] The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different parts.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0052] In the present disclosure, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0054] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0055] In some related technologies, the air duct assembly adopts a top air supply method of supplying air on both sides of the top and supplying air vertically in the middle of the top. These two top air supply methods have the following defects: the top air supply method on both sides of the top delivers less air to the top, resulting in a higher temperature in the middle area of ​​the top of the refrigerated box, a large temperature difference between the upper and lower parts of the refrigerated room, poor preservation effect, a high compressor start-up rate, and high energy consumption; in the top middle vertical air supply method, although the top temperature of the refrigerated box can be quickly reduced, due to the vertical direct blowing of air to the top of the refrigerated box liner, the temperature at the air duct outlet corresponding to the top space of the refrigerated box can easily enter a zero-crossing state, making it difficult to meet the performance test requirements, and a large amount of cooling capacity is wasted on the top, and the cooling capacity in the middle and lower parts of the refrigerated room is insufficient, which will also lead to a large temperature difference in the entire refrigerated room, poor preservation effect, a high compressor start-up rate, and high energy consumption.

[0056] Based on this, some embodiments of the present disclosure provide a cold storage chamber assembly and a refrigerator, which are used to alleviate problems such as unreasonable air supply structure in the cold storage chamber, which leads to large temperature difference in the cold storage chamber, poor preservation effect, high compressor start-up rate, and high energy consumption.

[0057] Figure 1 Schematic diagram of the structure of some embodiments of the refrigerating chamber assembly according to the present disclosure. Figure 1 In some embodiments, the refrigerating chamber assembly includes a refrigerating chamber 100 and an air duct assembly 200 .

[0058] The refrigerating chamber 100 includes a door body 300 disposed at the front.

[0059] The air duct assembly 200 is disposed in the refrigerating chamber 100 and is located on a side opposite to the door body 300 . The air duct assembly 200 is configured to operably supply air to at least one of the front and side surfaces of the refrigerating chamber 100 .

[0060] refer to Figure 1 , a door body 300 is arranged on the front of the refrigerating chamber 100, and an air duct assembly 200 is arranged on the back of the refrigerating chamber 100. The direction from the door body 300 to the air duct assembly 200 is a first direction X, that is, a thickness direction or a depth direction of the refrigerating chamber 100. The height direction of the refrigerating chamber 100 is a third direction Z. The width direction of the refrigerating chamber 100 is a second direction Y. Optionally, the first direction X is perpendicular to the second direction Y, the first direction X is perpendicular to the third direction Z, and the second direction Y is perpendicular to the third direction Z.

[0061] The air duct assembly 200 supplies air to the front of the refrigerating chamber 100, that is, the air outlet of the air duct assembly 200 faces the front of the refrigerating chamber 100. The air duct assembly 200 supplies air to the side of the refrigerating chamber 100, that is, the air outlet of the air duct assembly 200 faces the side of the refrigerating chamber 100, which is the side located in the width direction of the refrigerating chamber 100, or in other words, the side is the side located in the second direction Y of the refrigerating chamber 100.

[0062] In the above embodiment, the air duct assembly 200 is configured to operably supply air to at least one of the front and side surfaces of the cold storage chamber 100. The air supply method is flexible, and the corresponding air supply method can be selected according to different working conditions. It can reduce the start-up rate and energy consumption of the compressor, and make the temperature of the upper and lower parts of the cold storage chamber uniform, thereby improving the preservation effect.

[0063] For example: when the refrigeration of the cold storage room 100 is started for the first time, the temperature inside the cold storage room 100 is relatively high, and the air duct assembly 200 is controlled to supply air to the sides and the front of the cold storage room 100. By supplying air to the sides and the front of the cold storage room 100 at the same time, the temperature inside the cold storage room 100 can be quickly lowered, thereby improving the user experience.

[0064] As another example: due to the sinking of cold air, when the upper temperature in the refrigerating chamber 100 is higher than the preset temperature and the lower temperature is within the preset temperature range, the air duct assembly 200 can be controlled to supply air to the front of the refrigerating chamber 100, so that the cold air is directly blown to the inside of the refrigerating chamber 100, and the upper temperature of the refrigerating chamber 100 is quickly lowered, so that the upper and lower temperatures of the refrigerating chamber 100 are uniform, thereby improving the preservation effect and reducing the startup rate and energy consumption of the compressor.

[0065] In some embodiments, the duct assembly 200 is configured to operably supply air to an upper portion of the front of the refrigerating chamber 100 , and the duct assembly 200 is configured to operably supply air to an upper portion, a middle portion, and a lower portion of a side of the refrigerating chamber 100 .

[0066] In the above embodiment, the air duct assembly 200 supplies air to the upper part of the front of the refrigerating chamber, and the cold air is blown into the upper part of the front of the refrigerating chamber 100, so that the upper temperature of the refrigerating chamber 100 reaches the preset temperature as soon as possible, thereby reducing the energy consumption of the compressor, and then the cold air flows downward, covering the middle and lower parts of the refrigerating chamber, which can reduce the overall temperature of the refrigerating chamber 100. The air duct assembly 200 supplies air to the upper, middle and lower parts of the side of the refrigerating chamber 100, and the cold air flows horizontally, blows from the side to the center of the refrigerating chamber 100, and then diffuses upward or downward. This three-dimensional wind circulation mode can make the cold air cover all corners of the refrigerating chamber 100 more evenly, reducing the temperature difference. And because the cold air is more evenly distributed, the cold air dead corners in the refrigerating chamber 100 are reduced, and the food can be stored in a relatively consistent temperature environment, extending the shelf life of the food. Furthermore, the air duct assembly 200 supplies air to the side of the refrigerating chamber 100, which can prevent the cold air from blowing directly to the food, thereby improving the preservation effect of the food.

[0067] refer to Figure 2 and Figure 3 In some embodiments, the air duct assembly 200 includes a first air duct 11 , a second air duct 12 and a control member 3 .

[0068] The first air duct 11 is arranged to send air toward the side of the refrigerating chamber 100 .

[0069] The second air duct 12 is arranged to send air toward the front of the refrigerating chamber 100 .

[0070] The control element 3 is configured to guide the cold air to at least one of the first air duct 11 and the second air duct 12 .

[0071] In the above embodiment, according to the working condition and temperature of the refrigerating chamber 100, the control element 3 controls the cold air to enter the first air duct 11 or the second air duct 12, and realizes the side air supply or the front air supply, which can improve the uniformity of the temperature distribution and the preservation effect in the refrigerating chamber 100. And the control element 3 realizes the selection of the first air duct 11 or the second air duct 12, realizes the intelligent regulation of the air supply in the refrigerating chamber 100, and improves the user experience.

[0072] In some embodiments, the air duct assembly 200 includes a first air outlet 21 and a second air outlet 22 , and the control component 3 includes a first air door 31 and a second air door 32 .

[0073] The first damper 31 is disposed at the first air outlet 21 , and is configured to achieve communication or disconnection between the first air outlet 21 and the first air duct 11 .

[0074] The second damper 32 is disposed at the second air outlet 22 , and is configured to achieve communication or disconnection between the second air outlet 22 and the second air duct 12 .

[0075] In the above embodiment, the first air outlet 21 and the first air duct 11 can be connected or disconnected by the first air gate 31, and the second air outlet 22 and the second air duct 12 can be connected or disconnected by the second air gate 32. Therefore, the air supply direction can be flexibly adjusted as needed, and the flow rate of cold air can also be adjusted by adjusting the opening of the air gate, which is suitable for various cold air flow control needs.

[0076] In some embodiments, the first damper 31 and the second damper 32 are controlled by a unified control device to form a one-to-two damper structure. The one-to-two damper structure drives the two dampers simultaneously through a control device, and each damper can independently adjust its opening and closing degree so that the cold air can be flexibly distributed to different air ducts according to needs.

[0077] In some embodiments, the double damper structure formed by the first damper 31 and the second damper 32 can be controlled to open and close by a motor and a gear.

[0078] In some embodiments, the number of the first air ducts 11 is two, the two first air ducts 11 are connected to each other, and the second air duct 12 is located between the two first air ducts 11 .

[0079] In the above embodiment, the two first air ducts 11 are respectively on both sides of the second air duct 12, and the two first air ducts 11 respectively supply air to the two opposite sides of the refrigerating chamber 100, and the cold air flows along the two sides to the middle of the refrigerating chamber 100, and diffuses up and down to form a cycle, which can significantly improve the overall refrigeration quality in the refrigerating chamber 100, improve the uniformity of temperature distribution and the preservation effect of food. Furthermore, the two first air ducts 11 are interconnected, and can be connected or disconnected with the first air outlet 21 only through the first air door 31, which has a simple and compact structure and is easy to control.

[0080] In some embodiments, the air duct assembly 200 includes a first plate 1 and a second plate 2 .

[0081] A first air duct 11 and a second air duct 12 are provided on the first plate 1 .

[0082] The second plate 2 is disposed on the first plate 1 , and a third air duct 13 connecting the two first air ducts 11 is formed between the second plate 2 and the first plate 1 . A fourth air duct 14 connecting the second air outlet 22 and the second air duct 12 is formed on the side of the second plate 2 facing away from the first plate 1 .

[0083] In the above embodiment, a third air duct 13 connecting the two first air ducts 11 is formed between the first plate 1 and the second plate 2, and the first air duct 11 and the second air duct 12 are arranged on the side of the first plate 1 adjacent to the second plate 2. Therefore, the third air duct 13, the first air duct 11 and the second air duct 12 can be considered to be located at the same level, and the fourth air duct 14 is formed on the side of the second plate 2 away from the first plate 1. The fourth air duct 14 is equivalent to being located at another level, and the second air outlet 22 and the second air duct 12 are connected through the fourth air duct 14. Since the fourth air duct 14 and the third air duct 13 are located at different levels, one of the two first air ducts 11 is connected to the first air outlet 21, and the third air duct 13 is connected to the two first air ducts 11. Therefore, the cold air sent into the two first air ducts 11 through the first air outlet 21 will not interfere with the cold air sent into the second air duct 12 through the second air outlet 22 and the fourth air duct 14. The structure is compact and the design is ingenious.

[0084] In some embodiments, the number of second air ducts 12 is two, and the fourth air duct 14 includes a main path 141 and two branches 142. The two branches 142 are respectively connected to the two second air ducts 12 in a one-to-one correspondence. Both branches 142 are connected to the main path 141, and the main path 141 is connected to the second air outlet 22.

[0085] In the above embodiment, the number of the second air ducts 12 is two, but not limited to two. Multiple second air ducts 12 can improve the cooling effect of the front air supply. The fourth air duct 14 includes a main path 141 and two branches 142, the main path 141 is connected to the second air outlet 22, and the two branches 142 are connected to the two second air ducts 12 one by one. The structure of the second plate 2 does not need to be greatly modified to achieve the improvement of the front air supply volume and improve the cooling effect.

[0086] In the above embodiment, the first plate 1 and the second plate 2 are combined to form two layers of air ducts, the two first air ducts 11, the two second air ducts 12 and the third air duct 13 are located in the same layer, and the fourth air duct 14 is located in another layer.

[0087] The first air door 31 is opened, and the cold air from the first air outlet 21 enters one of the two first air ducts 11 , enters the other first air duct 11 through the third air duct 13 , and the cold air from the two first air ducts 11 is respectively sent to the sides of the refrigerating chamber 100 .

[0088] The second air door 32 is opened, and the cold air from the second air outlet 22 enters the main path 141 of the fourth air duct 14, and enters the two branch paths 142 through the main path 141, and then enters the two second air ducts 12 respectively. The cold air from the two second air ducts 12 is sent to the front of the refrigerating chamber 100.

[0089] The third air duct 13 is connected to the two first air ducts 11, which can realize air supply on both sides without interfering with the front air supply.

[0090] In some embodiments, the air duct assembly 200 further includes a cover plate 4 and a cover plate 5, and the cover plate 4, the second plate 2, the first plate 1 and the cover plate 5 are arranged in sequence. A fourth air duct 14 is formed between the cover plate 4 and the second plate 2, and a first air duct 11 and a second air duct 12 are formed between the cover plate 4 and the first plate 1. A third air duct 13 is formed between the first plate 1 and the second plate 2. A first air supply port 41 is provided on the cover plate 5, and the outlet of the first air supply port 41 faces the front of the refrigerating chamber 100.

[0091] In some embodiments, the air duct assembly 200 includes an air inlet 20 , a first plate 1 , and a second plate 2 .

[0092] The first plate 1 is provided with two first air ducts 11 and a second air duct 12 connected to the air inlet 20. The second air duct 12 is provided between the two first air ducts 11. The two first air ducts 11 are configured to supply air to the sides of the refrigerating chamber 100, and the second air duct 12 is configured to supply air to the front of the refrigerating chamber 100.

[0093] The second plate 2 is disposed on the first plate 1 , and a third air duct 13 connecting the two first air ducts 11 is formed between the second plate 2 and the first plate 1 . A fourth air duct 14 connecting the air inlet 20 and the second air duct 12 is formed on the side of the second plate 2 facing away from the first plate 1 .

[0094] In the above embodiment, the first plate 1 and the second plate 2 are combined to form a two-layer air duct, the two first air ducts 11, the second air duct 12 and the third air duct 13 are located on the same layer, and the fourth air duct 14 is located on another layer, and the front air supply can be achieved through the fourth air duct 14. The third air duct 13 connects the two first air ducts 11, which can realize air supply on both sides without interfering with the front air supply. The structural setting is simple and compact, and the design is ingenious.

[0095] In some embodiments, the air duct assembly 200 further includes a sealing cover 6 , which is disposed at the air inlet 20 and cooperates with the first air door 31 and the second air door 32 to prevent air leakage at the air inlet 20 .

[0096] In some embodiments, the air duct assembly 200 further includes a control component 3 , which is configured to guide the cold air from the air inlet 20 to at least one of the first air duct 11 and the second air duct 12 .

[0097] In the above embodiment, the control element 3 can control the cold air to enter the first air duct 11 or the second air duct 12. Therefore, the side air supply or the front air supply can be selected according to the working conditions and temperature conditions of the refrigerating chamber 100, which can improve the uniformity of temperature distribution and the preservation effect in the refrigerating chamber 100. And by using the control element 3 to select the first air duct 11 or the second air duct 12, the intelligent regulation of the air supply of the refrigerating chamber 100 can be realized, and the user experience can be improved.

[0098] In some embodiments, the air duct assembly 200 also includes at least two first air supply outlets 41 that are connected to the second air duct 12 and supply air to the front of the cold storage room 100. The at least two first air supply outlets 41 are arranged up and down, and the flow area of ​​the first air supply outlet 41 located above is larger than the flow area of ​​the first air supply outlet 41 located below.

[0099] In the above embodiment, among the at least two first air supply outlets 41 supplying air to the front of the cold storage room 100, the flow area of ​​the first air supply outlet 41 located at the top is larger than the flow area of ​​the first air supply outlet 41 located at the bottom. When the temperature balance of the cold storage room is to be maintained, the cooling capacity of the first air supply outlet 41 located at the top is larger than the cooling capacity of the first air supply outlet 41 located at the bottom, so it is easy to maintain the upper temperature of the cold storage room 100. Due to the sinking characteristic of cold air, the cooling capacity of the first air supply outlet 41 located at the bottom is smaller than the cooling capacity of the first air supply outlet 41 located at the top, so the lower temperature of the cold storage room 100 can be maintained within a preset temperature range through the sinking of cold air.

[0100] In some embodiments, the air duct assembly 200 includes at least two first air supply outlets 41 that are connected to the second air duct 12 and supply air to the front of the cold storage chamber 100. The at least two first air supply outlets 41 are arranged up and down, and the height of the first air supply outlet 41 located at the bottom is not lower than the middle position of the air duct assembly 200 in the height direction.

[0101] In the above embodiment, the first air supply port 41 is arranged at the upper part of the air duct assembly 200, and the cold air delivered by the first air supply port 41 is blown into the upper front part of the refrigerating chamber 100, which can quickly cool down the upper part of the refrigerating chamber 100, and then the cold air flows downward, covering the middle and lower parts of the refrigerating chamber, thereby improving the uniformity of temperature distribution in the refrigerating chamber 100.

[0102] In some embodiments, the air duct assembly 200 includes at least two first air supply outlets 41 disposed vertically and at least two second air supply outlets 42 disposed vertically, the at least two first air supply outlets 41 being configured to supply air to the front of the refrigerating chamber 100, the two second air supply outlets 42 being configured to supply air to the sides of the refrigerating chamber 100, the position of the first air supply outlet 41 located at the top being higher than the position of the second air supply outlet 42 located at the top, and the position of the first air supply outlet 41 located at the bottom being higher than the position of the second air supply outlet 42 located at the bottom.

[0103] In the above embodiment, the overall position of at least two first air supply ports 41 is higher than the position of at least two second air supply ports 42. At least two first air supply ports 41 mainly supply air to the upper part of the front of the refrigerating chamber, and the cold air blows into the upper part of the front of the refrigerating chamber 100, which can quickly cool down the upper part of the refrigerating chamber 100, and then the cold air flows downward to cover the middle and lower parts of the refrigerating chamber, which can quickly cool down the entire refrigerating chamber 100. At least two second air supply ports 42 mainly supply air to the upper, middle and lower parts of the side of the refrigerating chamber 100, and the cold air flows horizontally, blows from the side to the center of the refrigerating chamber 100, and then diffuses upward or downward, which can more evenly cover all corners of the refrigerating chamber 100, reduce the temperature difference, make the cold air distribution more uniform, reduce the cold air dead corners in the refrigerating chamber 100, and enable the food to be stored in a relatively consistent temperature environment, extending the shelf life of the food.

[0104] In some embodiments, the refrigerating chamber assembly further includes a controller, and the controller is configured to control the air duct assembly 200 to supply air to the side and front of the refrigerating chamber 100 when the refrigerating chamber 100 starts cooling for the first time.

[0105] In the above embodiment, when the refrigeration of the cold storage room 100 is started for the first time, the temperature in the cold storage room 100 is relatively high. By controlling the air duct assembly 200 by the controller to supply air to the front and sides of the cold storage room 100 at the same time, the temperature in the cold storage room 100 can be quickly reduced, and the refrigeration efficiency of the compressor can be improved. In addition, by controlling the air supply mode of the air duct assembly 200 by the controller, intelligent regulation of the air supply in the cold storage room 100 can be achieved, thereby improving the user experience.

[0106] In some embodiments, the refrigerating chamber assembly further includes a controller, a first temperature detecting member 51 and a second temperature detecting member 52 .

[0107] refer to Figure 4 The second temperature detecting component 52 is arranged below the first temperature detecting component 51 .

[0108] Among them, the controller is electrically connected to the first temperature detection component 51 and the second temperature detection component 52, and the controller is configured to control the air duct assembly 200 to supply air to the front of the cold storage room 100 when the temperature detected by the second temperature detection component 52 meets the preset temperature and the temperature detected by the first temperature detection component 51 is greater than the preset temperature.

[0109] In the above embodiment, due to the characteristic of cold air sinking, when the temperature detected by the second temperature detection component 52 meets the preset temperature and the temperature detected by the first temperature detection component 51 is greater than the preset temperature, the air duct assembly 200 is controlled to supply air to the front of the refrigerating chamber 100. The front air supply is mainly blown directly from the upper part of the refrigerating chamber 100 to the front, which can quickly reduce the temperature of the upper part of the refrigerating chamber 100 and make the temperature of the upper part of the refrigerating chamber 100 meet the preset temperature, thereby improving the temperature uniformity in the refrigerating chamber 100 and reducing energy consumption.

[0110] Optionally, the first temperature detection member 51 is located at a position 1 / 3 of the height of the refrigerating chamber 100 from the top, and the first temperature detection member 51 is located in the middle of the width direction of the refrigerating chamber 100. The second temperature detection member 52 is located at a position 2 / 3 of the height of the refrigerating chamber from the top, and the second temperature detection member 52 is located in the middle of the width direction of the refrigerating chamber 100.

[0111] In some embodiments, the first temperature detecting element 51 is used to control the opening and closing of the second damper 32 , and the second temperature detecting element 52 is used to control the opening and closing of the first damper 31 .

[0112] In some embodiments, the air supply area of ​​the first damper 31 is larger than the air supply area of ​​the second damper 32 .

[0113] In some embodiments, the controller is configured to control the air duct assembly 200 to stop supplying air to the refrigeration chamber 100 when the temperatures detected by the first temperature detection element 51 and the second temperature detection element 52 are both within a preset temperature range, and thereafter, when the temperature detected by the first temperature detection element 51 is greater than a preset temperature, control the air duct assembly 200 to supply air to the front of the refrigeration chamber 100.

[0114] In the above embodiment, when the temperatures detected by the first temperature detection component 51 and the second temperature detection component 52 both meet the preset temperatures, the air duct assembly 200 is controlled to stop supplying air to the refrigerating chamber 100. As the cold amount in the refrigerating chamber 100 is lost and due to the sinking of cold air, the temperature of the upper part of the refrigerating chamber 100 will be higher than the preset temperature before the temperature of the lower part of the refrigerating chamber 100. Therefore, when the temperature detected by the first temperature detection component 51 is greater than the preset temperature, the air duct assembly 200 is controlled to supply air to the front of the refrigerating chamber 100. The front air supply is mainly blown directly from the upper part of the refrigerating chamber 100 to the front, which can quickly reduce the temperature of the upper part of the refrigerating chamber 100 and make the temperature of the upper part of the refrigerating chamber 100 meet the preset temperature. After that, the sinking of cold air can cool the middle and lower parts of the refrigerating chamber 100, so that the temperature in the refrigerating chamber 100 is uniform. Since there is no need to supply air to the front and sides of the refrigerating chamber 100 at the same time, energy consumption can be reduced.

[0115] In some embodiments, the upper and lower temperature differences of the cold storage chamber 100 can be detected by the first temperature detection component 51 and the second temperature detection component 52, which is beneficial to controlling the opening and closing of the one-to-two dampers, so that the upper and lower temperature differences of the cold storage chamber are maintained within a range of about 0.5°. The three-dimensional wind circulation mode ensures that the temperature of the cold storage chamber 100 can quickly reach the preset temperature. Therefore, by controlling the upper and lower temperature differences of the cold storage chamber 100 through dual temperature detection components and the one-to-two dampers, the startup rate of the compressor can be significantly reduced, thereby achieving energy saving and consumption reduction and improving the preservation effect.

[0116] In some embodiments, the first temperature detecting member 51 includes a temperature sensor.

[0117] In some embodiments, the second temperature detection member 52 includes a temperature sensor.

[0118] Some embodiments of the present disclosure also provide a refrigerator, which includes the refrigerating chamber assembly in any of the above embodiments.

[0119] At present, the refrigerator market is developing in the direction of high-end and diversification, and air-cooled frost-free refrigerators are becoming more and more popular among consumers.

[0120] Air-cooled frost-free refrigerators are generally equipped with a refrigerator compartment, a temperature-changing room, and a freezer compartment. A freezing evaporator and a fan are installed at the rear of the freezer compartment, and a circulating air duct assembly is installed in the three compartments. With the help of fan forced convection, the cold air from the evaporator is sent into the refrigerator compartment through the air duct assembly of the refrigerator compartment, thereby achieving refrigeration of the refrigerator compartment.

[0121] In the disclosed embodiment, the refrigerating chamber assembly adopts a one-to-two damper, a double-layer air duct structure and a dual temperature detection component control, which can reduce the upper and lower temperature differences of the refrigerating chamber 100, improve the preservation effect and reduce energy consumption.

[0122] Reference below Figures 1 to 4 , some specific embodiments of the cold storage chamber assembly are listed.

[0123] In some specific embodiments, the refrigerating chamber assembly includes a refrigerating chamber 100 and an air duct assembly 200. A door body 300 is disposed on the front of the refrigerating chamber 100, and the air duct assembly 200 is disposed on the back of the refrigerating chamber 100.

[0124] The air duct assembly 200 includes an air inlet 20, a first plate 1, a second plate 2, a control member 3, a cover plate 4, a cover plate 5, a controller, a first temperature detection member 51 and a second temperature detection member 52. The air inlet 20 includes a first air outlet 21 and a second air outlet 22, and the control member 3 includes a first air door 31 and a second air door 32. The first air door 31 is provided at the first air outlet 21. The second air door 32 is provided at the second air outlet 22.

[0125] Two first air ducts 11 and two second air ducts 12 are provided on the first plate 1. The two second air ducts 12 are located between the two first air ducts 11. The two first air ducts 11 are configured to supply air to the sides of the refrigerating chamber 100. The two second air ducts 12 are configured to supply air to the front of the refrigerating chamber 100.

[0126] The second plate 2 is arranged on the first plate 1, and a third air duct 13 connecting the two first air ducts 11 is formed between the second plate 2 and the first plate 1, and a fourth air duct 14 connecting the second air outlet 22 and the second air duct 12 is formed on the side of the second plate 2 away from the first plate 1. The fourth air duct 14 includes a main path 141 and two branch paths 142, and the two branch paths 142 are respectively connected to the two second air ducts 12 in a one-to-one correspondence, and the two branch paths 142 are connected to the main path 141, and the main path 141 is connected to the second air outlet 22. The first damper 31 is configured to achieve the connection or disconnection of the first air outlet 21 and the first air duct 11. The second damper 32 is configured to achieve the connection or disconnection of the second air outlet 22 and the second air duct 12.

[0127] The first air door 31 is opened, and the cold air from the first air outlet 21 enters one of the two first air ducts 11 , enters the other first air duct 11 through the third air duct 13 , and the cold air from the two first air ducts 11 is respectively sent to the sides of the refrigerating chamber 100 .

[0128] The second air door 32 is opened, and the cold air from the second air outlet 22 enters the main path 141 of the fourth air duct 14, and enters the two branch paths 142 through the main path 141, and then enters the two second air ducts 12 respectively. The cold air from the two second air ducts 12 is sent to the front of the refrigerating chamber 100, forming a three-dimensional air supply circulation mode, reducing the upper and lower temperature difference of the refrigerating chamber, reducing the energy consumption of the compressor, and improving the preservation effect.

[0129] The cover plate 4, the second plate 2, the first plate 1 and the cover plate 5 are arranged in sequence. A fourth air duct 14 is formed between the cover plate 4 and the second plate 2, and a first air duct 11 and a second air duct 12 are formed between the cover plate 4 and the first plate 1. A third air duct 13 is formed between the first plate 1 and the second plate 2. A first air supply port 41 is provided on the cover plate 5, and the outlet of the first air supply port 41 faces the front of the refrigerating chamber 100.

[0130] The first temperature detecting member 51 and the second temperature detecting member 52 are disposed on the cover plate 5 , and the second temperature detecting member 52 is disposed below the first temperature detecting member 51 .

[0131] In the above specific embodiment, usually due to the sinking of cold air, the upper temperature of the refrigerating chamber 100 is 2° to 3° higher than the lower temperature. If the preset temperature of the refrigerating chamber is set relatively low, the lower temperature of the refrigerating chamber 100 may pass zero and the test will fail.

[0132] Based on this, in this specific embodiment, the temperature in the refrigerating chamber is detected by two temperature detecting components, and the air supply of the air duct assembly 200 is controlled according to the temperature to improve the temperature uniformity in the refrigerating chamber, as follows:

[0133] When the refrigerator is turned on for the first time, the first damper 31 and the second damper 32 are both opened, and cold is supplied to the refrigerating chamber 100 simultaneously through the first damper 31 and the second damper 32 , and the cold is continuously supplied to the refrigerating chamber 100 .

[0134] When the second temperature detection component 52 detects that the temperature meets the preset temperature, the first damper 31 is closed. At this time, if the temperature detected by the first temperature detection component 51 is greater than the preset temperature, the second damper 32 continues to remain open and continues to supply cold air to the refrigerator compartment until the preset temperature is met, and the second damper 32 is closed.

[0135] After the compressor stops, as the temperature of the refrigerating chamber rises, when the first temperature detecting member 51 detects that the temperature is higher than the preset temperature again, the second air door 32 opens, and the cold air enters the second air duct 12 through the fourth air duct 14, and then supplies air from the first air supply port 41 to the front of the refrigerating chamber 100. The first air supply port 41 supplies cold air to the upper part of the refrigerating chamber 100, so that the upper temperature of the refrigerating chamber 100 reaches the preset temperature as soon as possible, maintains the temperature balance of the refrigerating chamber, reduces the temperature difference between the upper and lower parts of the refrigerating chamber, and improves the preservation effect. Since the first air door 31 does not need to be opened, the cold air supply is reduced, thereby reducing energy consumption.
