[0055] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered part of the specification where appropriate.

[0056] In some related technologies, the air duct assembly adopts top-side air supply and top-middle vertical air supply methods. These two methods have the following drawbacks: Top-side air supply delivers less air to the top, resulting in a higher temperature in the middle area of ​​the top of the refrigerator, a larger temperature difference between the top and bottom of the refrigerator compartment, poor preservation effect, and a higher compressor operating rate and energy consumption. Top-middle vertical air supply, although it can quickly lower the temperature at the top of the refrigerator, causes the temperature at the air duct opening at the top of the refrigerator compartment to easily drop below zero, making it difficult to meet performance testing requirements. Moreover, a large amount of cooling capacity is wasted at the top, while the cooling capacity in the middle and lower parts of the refrigerator compartment is insufficient, which also leads to a larger temperature difference in the entire refrigerator compartment, poor preservation effect, and a higher compressor operating rate and energy consumption.

[0057] Based on this, some embodiments of the present invention provide a refrigerator compartment component and a refrigerator to alleviate problems such as unreasonable air supply structure in the refrigerator compartment, resulting in large temperature difference in the refrigerator compartment, poor preservation effect, high compressor start-up rate, and high energy consumption.

[0058] Figure 1 This is a structural schematic diagram of some embodiments of the refrigerator compartment assembly according to this utility model. (Reference) Figure 1 In some embodiments, the refrigerator compartment assembly includes a refrigerator compartment 100 and an air duct assembly 200.

[0059] The refrigerator compartment 100 includes a door 300 located on the front.

[0060] The air duct assembly 200 is disposed inside the refrigerator compartment 100 and located on the side opposite to the door 300. The air duct assembly 200 is configured to operably supply air to at least one of the front and side of the refrigerator compartment 100.

[0061] refer to Figure 1 The refrigerator compartment 100 has a door 300 on its front and an air duct assembly 200 on its back. The direction from the door 300 to the air duct assembly 200 is the first direction X, which is the thickness or depth direction of the refrigerator compartment 100. The height direction of the refrigerator compartment 100 is the third direction Z. The width direction of the refrigerator compartment 100 is the 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.

[0062] The air duct assembly 200 blows air to the front of the refrigeration chamber 100, that is, the air outlet of the air duct assembly 200 faces the front of the refrigeration chamber 100. The air duct assembly 200 blows air to the side of the refrigeration chamber 100, that is, the air outlet of the air duct assembly 200 faces the side of the refrigeration chamber 100, which is the side in the width direction of the refrigeration chamber 100, or in other words, which is the side in the second direction Y of the refrigeration chamber 100.

[0063] In the above embodiment, the air duct assembly 200 is configured to be operable to blow air to at least one of the front and the side of the refrigeration chamber 100, the air blowing manner is flexible, and the corresponding air blowing manner can be selected according to different working conditions, so as to reduce the start-up rate and energy consumption of the compressor, make the temperature of the refrigeration chamber uniform, and improve the preservation effect.

[0064] For example, in the case of starting refrigeration for the first time, the temperature in the refrigeration chamber 100 is relatively high, and the air duct assembly 200 is controlled to blow air to the side and the front of the refrigeration chamber 100. By blowing air to the side and the front of the refrigeration chamber 100 at the same time, the temperature in the refrigeration chamber 100 can be quickly reduced, and the user experience can be improved.

[0065] For another example, due to the sinking of cold air, the temperature at the upper part of the refrigeration chamber 100 is higher than the preset temperature, and the temperature at the lower part is within the preset temperature range. In this case, the air duct assembly 200 can be controlled to blow air to the front of the refrigeration chamber 100, so that the cold air directly blows to the inside of the refrigeration chamber 100, the temperature at the upper part of the refrigeration chamber 100 is quickly reduced, the temperature of the refrigeration chamber 100 is uniform, the preservation effect is improved, and the start-up rate and energy consumption of the compressor are reduced.

[0066] In some embodiments, the air duct assembly 200 is configured to be operable to blow air to the upper part of the front of the refrigeration chamber 100, and the air duct assembly 200 is configured to be operable to blow air to the upper part, the middle part, and the lower part of the side of the refrigeration chamber 100.

[0067] In the above embodiment, the air duct assembly 200 blows air to the upper part of the front of the refrigeration chamber, the cold air is blown into the upper part of the front of the refrigeration chamber 100, so that the temperature of the upper part of the refrigeration 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 to cover the middle and lower parts of the refrigeration chamber, so that the overall temperature of the refrigeration chamber 100 can be reduced. The air duct assembly 200 blows air to the upper, middle and lower parts of the side of the refrigeration chamber 100, the cold air flows horizontally, blows from the side to the center of the refrigeration chamber 100, and then diffuses upward or downward. This three-dimensional air circulation mode can make the cold air more evenly cover each corner of the refrigeration chamber 100, thereby reducing the temperature difference. Moreover, due to the more uniform distribution of cold air, the dead angle of cold air in the refrigeration chamber 100 is reduced, and the food materials can be stored in a relatively consistent temperature environment, thereby prolonging the preservation period of the food. Furthermore, the air duct assembly 200 blows air to the side of the refrigeration chamber 100, which can avoid blowing cold air directly to the food materials, thereby improving the preservation effect of the food materials.

The cold air flows along the two sides to the middle of the refrigeration chamber 100 and diffuses upward and downward, forming a circulation, which can significantly improve the overall refrigeration quality in the refrigeration chamber 100, improve the temperature distribution uniformity and the preservation effect of food materials. Furthermore, the two first air ducts 11 are connected to each other, and the connection or disconnection between the first air port 21 and the first air duct 11 can be realized only by the first air door 31, which has a simple and compact structure and is easy to control.

Then, the cold air flows downwards, covering the middle and lower parts of the refrigerator compartment, enabling rapid overall cooling of the refrigerator compartment 100. The at least two second air outlets 42 primarily supply air to the upper, middle, and lower sides of the refrigerator compartment 100. The cold air flows laterally, blowing from the sides towards the center of the refrigerator compartment 100, and then diffusing upwards or downwards. This allows for more even coverage of all corners of the refrigerator compartment 100, reducing temperature differences and making the cold air distribution more uniform. This reduces dead zones in the cold air supply within the refrigerator compartment 100, allowing food to be stored in a relatively uniform temperature environment and extending its shelf life.

[0105] In some embodiments, the refrigerator compartment assembly further includes a controller configured to control the air duct assembly 200 to deliver air to the sides and front of the refrigerator compartment 100 when the refrigerator compartment 100 is first started to cool.

[0106] In the above embodiment, when the refrigerator compartment 100 is started to cool for the first time, the temperature inside the refrigerator compartment 100 is relatively high. By controlling the air duct assembly 200 to simultaneously deliver air to the front and sides of the refrigerator compartment 100 through the controller, the temperature inside the refrigerator compartment 100 can be quickly reduced, improving the cooling efficiency of the compressor. Furthermore, by controlling the air delivery mode of the air duct assembly 200 through the controller, intelligent regulation of the air delivery inside the refrigerator compartment 100 can be achieved, improving the user experience.

[0107] In some embodiments, the refrigerator compartment assembly further includes a controller, a first temperature sensor 51, and a second temperature sensor 52.

[0108] refer to Figure 4 The second temperature detection element 52 is located below the first temperature detection element 51.

[0109] The controller is electrically connected to the first temperature sensor 51 and the second temperature sensor 52. The controller is configured to control the air duct assembly 200 to deliver air to the front of the refrigerator compartment 100 when the temperature detected by the second temperature sensor 52 meets the preset temperature and the temperature detected by the first temperature sensor 51 is greater than the preset temperature.

[0110] In the above embodiment, due to the characteristics of the cold air sinking, when the temperature detected by the second temperature detecting member 52 meets the preset temperature, and the temperature detected by the first temperature detecting member 51 is greater than the preset temperature, the air duct assembly 200 is controlled to blow air to the front of the refrigerating chamber 100, the front blowing air is mainly blown out directly from the upper portion of the refrigerating chamber 100 to the front, which can rapidly reduce the temperature of the upper portion of the refrigerating chamber 100, so that the temperature of the upper portion of the refrigerating chamber 100 meets the preset temperature, the uniformity of the temperature in the refrigerating chamber 100 is improved, and the energy consumption is reduced.

[0111] Optionally, the first temperature detecting member 51 is located at a position 1 / 3 of the height of the refrigerating chamber 100 from the top, and the first temperature detecting member 51 is located at the middle of the width of the refrigerating chamber 100. The second temperature detecting member 52 is located at a position 2 / 3 of the height of the refrigerating chamber 100 from the top, and the second temperature detecting member 52 is located at the middle of the width of the refrigerating chamber 100.

[0112] In some embodiments, the first temperature detecting member 51 is used to control the opening and closing of the second air door 32, and the second temperature detecting member 52 is used to control the opening and closing of the first air door 31.

[0113] In some embodiments, the blowing area of the first air door 31 is greater than the blowing area of the second air door 32.

[0114] In some embodiments, the controller is configured to, when the temperatures detected by the first temperature detecting member 51 and the second temperature detecting member 52 are both in the preset temperature range, control the air duct assembly 200 to stop blowing air to the refrigerating chamber 100, and then, when the temperature detected by the first temperature detecting member 51 is greater than the preset temperature, control the air duct assembly 200 to blow air to the front of the refrigerating chamber 100.

[0115] In the above embodiment, when the temperatures detected by the first temperature detecting member 51 and the second temperature detecting member 52 both meet the preset temperature, the air duct assembly 200 is controlled to stop blowing air to the refrigerating chamber 100, and as the cold energy in the refrigerating chamber 100 is lost, and due to the sinking of the cold air, the temperature of the upper portion of the refrigerating chamber 100 will be higher than the preset temperature before the temperature of the lower portion of the refrigerating chamber 100, therefore, when the temperature detected by the first temperature detecting member 51 is greater than the preset temperature, the air duct assembly 200 is controlled to blow air to the front of the refrigerating chamber 100, the front blowing air is mainly blown out directly from the upper portion of the refrigerating chamber 100 to the front, which can rapidly reduce the temperature of the upper portion of the refrigerating chamber 100, so that the temperature of the upper portion of the refrigerating chamber 100 meets the preset temperature, and then the sinking of the cold air can cool the middle and lower portions of the refrigerating chamber 100, so that the temperature in the refrigerating chamber 100 is uniform, and the energy consumption is reduced.

[0116] In some embodiments, the upper and lower temperature difference of the refrigerating chamber 100 can be detected by the first temperature detecting member 51 and the second temperature detecting member 52, which is conducive to controlling the opening and closing of the one-to-two air door, so that the upper and lower temperature difference of the refrigerating chamber is kept within a range of about 0.5°. The three-dimensional air circulation mode ensures that the temperature of the refrigerating chamber 100 can quickly reach the preset temperature. Therefore, by controlling the upper and lower temperature difference of the refrigerating chamber 100 through the double temperature detecting members and the one-to-two air door, the starting rate of the compressor can be obviously reduced, energy consumption can be saved, and the purpose of improving the preservation effect can be achieved.

[0117] In some embodiments, the first temperature detecting member 51 comprises a temperature sensor.

[0118] In some embodiments, the second temperature detecting member 52 comprises a temperature sensor.

[0127] The second plate 2 is arranged on the first plate 1, and the second plate 2 and the first plate 1 form a third air duct 13 communicating the two first air ducts 11. The side of the second plate 2 away from the first plate 1 forms a fourth air duct 14 communicating the second air port 22 and the second air duct 12. The fourth air duct 14 includes a main path 141 and two branch paths 142, the two branch paths 142 are respectively in one-to-one correspondence with the two second air ducts 12, the two branch paths 142 are connected to the main path 141, and the main path 141 is connected to the second air port 22. The first air door 31 is configured to realize the communication or disconnection of the first air port 21 and the first air duct 11. The second air door 32 is configured to realize the communication or disconnection of the second air port 22 and the second air duct 12.

[0128] The first air door 31 is opened, and the cold air of the first air port 21 enters one of the two first air ducts 11, and enters the other first air duct 11 through the third air duct 13. The cold air of the two first air ducts 11 is respectively supplied to the side of the refrigeration chamber 100.

[0129] The second air door 32 is opened, and the cold air of the second air port 22 enters the main path 141 of the fourth air duct 14, enters the two branch paths 142 through the main path 141, and then enters the two second air ducts 12 respectively, and the cold air of the two second air ducts 12 is supplied to the front of the refrigeration chamber 100, forming a three-dimensional air supply circulation mode, reducing the temperature difference between the upper and lower parts of the refrigeration chamber, reducing the energy consumption of the compressor, and improving the preservation effect.

[0130] The cover plate 4, the second plate 2, the first plate 1 and the cover plate 5 are arranged in sequence. The fourth air duct 14 is formed between the cover plate 4 and the second plate 2, and the first air duct 11 and the second air duct 12 are formed between the cover plate 4 and the first plate 1.

The cover plate 5 is provided with a first air supply port 41, and the outlet of the first air supply port 41 faces the front of the refrigeration chamber 100.

[0131] The first temperature detection member 51 and the second temperature detection member 52 are arranged on the cover plate 5, and the second temperature detection member 52 is arranged below the first temperature detection member 51.

[0132] In the above specific embodiments, generally, due to the sinking of cold air, the temperature of the upper part of the refrigeration chamber 100 is 2° to 3° higher than that of the lower part. If the preset temperature of the refrigeration chamber is set relatively low, the temperature of the lower part of the refrigeration chamber 100 may be zero or less, which is unqualified in testing.

[0133] Based on this, in this specific embodiment, the temperature inside the refrigeration chamber is detected by two temperature detection members, and the air supply of the air duct assembly 200 is controlled according to the temperature to improve the temperature uniformity inside the refrigeration chamber, as follows:

[0134] When the refrigerator is started for the first time, the first air door 31 and the second air door 32 are both opened, and cold air is supplied to the refrigeration chamber 100 through the first air door 31 and the second air door 32 at the same time, and the refrigeration chamber 100 is continuously supplied with cold air.

[0135] When the second temperature detection member 52 detects that the temperature meets the preset temperature, the first air door 31 is closed, at this time, if the temperature detected by the first temperature detection member 51 is greater than the preset temperature, the second air door 32 continues to maintain open, and continues to supply cold air to the refrigeration chamber until the preset temperature is met, and the second air door 32 is closed.

[0136] After the compressor is stopped, as the temperature of the refrigeration chamber rises, when the first temperature detection member 51 detects that the temperature is higher than the preset temperature again, the second air door 32 is opened, and cold air enters the second air duct 12 through the fourth air duct 14, and then is supplied to the front of the refrigeration chamber 100 from the first air supply port 41, and the first air supply port 41 supplies cold air to the upper part of the refrigeration chamber 100, so that the temperature of the upper part of the refrigeration chamber 100 reaches the preset temperature as soon as possible, maintains the temperature balance of the refrigeration chamber, reduces the temperature difference between the upper and lower parts of the refrigeration 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.
