[0042] In the current field of refrigeration technology, refrigerators and other refrigeration equipment, due to their spacious internal storage, generally face the problem of uneven distribution of cold air. This problem is particularly pronounced in larger spaces, making it difficult to uniformly lower the temperature of the entire cabinet to the set level. To achieve a balanced temperature drop within the cabinet, the cooling process time is usually extended, which not only increases the equipment's operating cycle but also leads to higher energy consumption.

[0043] This application provides an air duct structure and a refrigeration device to solve the problem of high energy consumption in existing refrigeration devices. The following will be described in conjunction with the attached... Figure 1-8 Please provide an explanation.

[0044] The air duct structure provided in this application embodiment can be applied to refrigeration equipment such as refrigerators and freezers. The refrigerator can be a single-door refrigerator, a double-door refrigerator, or a three-door refrigerator. This application does not impose any restrictions on this.

[0045] For example, taking a refrigerator as an example, a refrigerator may include a refrigerator compartment and a freezer compartment, and an air duct structure may be applied to the refrigerator compartment or the freezer compartment.

[0046] According to one embodiment of this application, reference is made to... Figure 1 and Figure 2 As shown, the air duct structure includes an air duct plate 100, a baffle plate 200, a sliding member 300, and a driving member 400. The air duct plate 100 forms a cooling air duct and at least two first air outlets 110 connected to the cooling air duct. The at least two first air outlets 110 are spaced apart. The baffle plate 200 is correspondingly arranged with the first air outlets 110 and is slidably disposed on the first air outlets 110. The sliding member 300 is slidably disposed on the air duct plate 100. Both sides of the sliding member 300 are connected to the baffle plate 200, so that the position of the baffle plate 200 can be adjusted as needed. The driving member 400 is used to drive the sliding member 300 to slide, so as to drive the baffle plate 200 to open one of the first air outlets 110.

[0047] The multiple first air outlets 110 can be spaced apart horizontally or vertically.

[0048] Optionally, there can be two first air outlets 110, with the two first air outlets located on opposite sides of the duct plate 100; alternatively, there can be three, four, or more first air outlets 110, with multiple first air outlets 110 spaced apart. The attached figure shows an embodiment with two first air outlets 110, and the duct structure will be described below using two first air outlets 110 as an example.

[0049] For example, the air duct plate 100 may include a front cover plate and a rear cover plate, which are interlocked to form a cooling air duct. First air outlets 110 are provided on both sides of the air duct plate 100. These first air outlets 110 are auxiliary air outlets used to provide auxiliary airflow to the cooling room. These opposing sides can be the left and right sides of the cooling equipment, or the upper and lower sides, or the front and rear sides of the cooling equipment, etc., and can be arranged according to actual needs. This embodiment does not specify any particular arrangement.

[0050] Optionally, the drive unit 400 can be a motor that can rotate forward and reverse, and the motor can be fixed to the front cover of the air duct plate 100 by screws.

[0051] By setting first air outlets 110 on both sides of the air duct plate 100, and cooperating with the sliding of the baffle plate 200, the opening and closing of the first air outlets 110 can be achieved, which can adjust the temperature according to the temperature requirements of different areas inside the refrigerator, effectively solving the problem of uneven temperature distribution. When a higher temperature is detected on one side of the refrigeration equipment, the drive component 400 can respond quickly, and drive the baffle plate 200 to open the first air outlet 110 of the corresponding area through the sliding component 300, so as to realize auxiliary air outlet in that area. By increasing the air outlet intensity of the higher temperature area, the temperature of that area can be lowered more quickly, thereby reducing the energy consumption of the refrigeration equipment during the refrigeration process and improving the energy-saving effect.

[0052] In one alternative implementation, refer to Figure 1 and Figure 2 As shown, the air duct plate 100 also includes a second air outlet 120 (i.e., the main air outlet) connected to the cooling air duct; the air duct structure includes an air guide plate 600, which is rotatably disposed at the second air outlet 120, and the air guide plate 600 is connected to a sliding member 300. The sliding member 300 is configured to drive the air guide plate 600 to rotate during sliding, thereby adjusting the air outlet direction and air outlet intensity.

[0053] For example, the air duct plate 100 is provided with a second air outlet 120, the area of ​​which is larger than that of the first air outlet 110, and it plays a major role in air supply and cooling of the refrigerated room. The air guide plate 600 at the second air outlet 120 is rotatably configured to adjust the air outlet direction. The main function of the air guide plate 600 is to guide the cold air flowing out of the second air outlet 120, ensuring that the cold air can be distributed in the required direction and range.

[0054] In this embodiment, the sliding member 300 is not only connected to the baffle plate 200, but also connected to the air guide plate 600. When the sliding member 300 slides on the air duct plate 100, it can simultaneously drive the air guide plate 600 to rotate, thereby adjusting the air outlet direction and air outlet intensity. This allows the cold air to be distributed more evenly throughout the refrigerator space, improving refrigeration efficiency and reducing energy consumption.

[0055] Optionally, the second air outlet 120 is located above the first air outlet 110, and the second air outlet 120 is elongated to cover a larger air outlet area and reduce cooling dead zones.

[0056] Optionally, the driving component 400 can be a motor, and the output shaft of the motor is equipped with a gear. The sliding component 300 is provided with a rack, and the gear and rack are meshed and connected. The transmission mechanism of the gear and rack enables the motor to rotate and drive the sliding component 300 to slide, thereby achieving precise control of the sliding position of the sliding component 300. This allows for accurate control of the angle of the air guide plate 600 and the opening of the first air outlet 110, and precise adjustment of the air outlet direction and intensity.

[0057] It is understandable that the air outlet direction of the air guide plate 600 is on the same side as the opening of the first air outlet 110. For example, when the temperature on the left side of the refrigerator is detected to be higher, the air guide plate 600 rotates to the left to outlet air on the left side, and the corresponding first air outlet 110 on the left side also opens to assist in outlet air, so as to enhance the outlet air effect on the left side and quickly cool down the left side.

[0058] In one alternative implementation, refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the sliding member 300 is provided with a sliding groove 320, and the air guide plate 600 is provided with a rotating shaft part 610 and a sliding part 620. The rotating shaft part 610 is rotatably connected to the air duct plate 100, and the sliding part 620 is slidably disposed in the sliding groove 320, so that when the sliding member 300 slides, the sliding part 620 and the sliding groove 320 can generate relative movement, thereby driving the air guide plate 600 to rotate around the rotating shaft part 610, thereby realizing the adjustment of the air outlet direction of the second air outlet 120.

[0059] In one optional implementation, combined with Figure 1 and Figure 3 As shown, the air duct structure includes a connecting rod 500, the middle of which is rotatably connected to the air duct plate 100. One end of the connecting rod 500 is connected to the sliding member 300, and the other end is connected to the baffle plate 200. When the sliding member 300 slides, it is suitable to drive the connecting rod 500 to rotate and drive the baffle plate 200 to move to open or close the first air outlet 110.

[0060] In this embodiment, when the driving component 400, such as the motor-driven sliding component 300, slides on the air duct plate 100, the sliding component 300 will drive the connecting rod 500 to rotate through the transmission connection, thereby driving the baffle plate 200 at the other end of the connecting rod 500 to move, thereby controlling the opening degree of the first air outlet 110.

[0061] The sliding member 300 also serves to adjust the angle of the air guide plate 600 and the position of the baffle plate, thereby enabling the drive member 400 to simultaneously adjust the air outlet direction of the second air outlet 120 and the opening of the first air outlet 110. While better controlling the distribution of cold air, the mechanical linkage between the connecting rod 500 and the sliding member 300 can achieve a compact structural design, save space, and improve the space utilization efficiency inside the refrigerator.

[0062] In one alternative implementation, refer to Figure 3 and Figure 4 As shown, a guide groove 510 is provided at one end of the connecting rod 500, and a transmission part 310 is provided on the sliding member 300. The transmission part 310 passes through the guide groove 510 so as to drive the connecting rod 500 to rotate when the sliding member 300 slides.

[0063] The guide groove 510 is located at one end of the connecting rod 500. Its function is to limit the movement trajectory of the transmission part 310 and ensure that the sliding member 300 can accurately drive the connecting rod 500 to rotate when sliding. The shape and size of the guide groove 510 are designed according to the shape and movement requirements of the transmission part 310. It can be a straight groove or a curved groove to facilitate the smooth movement of the transmission part 310 in the groove.

[0064] The transmission part 310 can be integrally set with the sliding part 300. The transmission part 310 can also be a pin, cam, gear or other mechanical part that can cooperate with the guide groove 510. When the sliding part 300 moves, the transmission part 310 can move synchronously and be precisely guided in the guide groove 510, pushing the connecting rod 500 to rotate, and finally driving the baffle plate 200 to move, so as to open or close the first air outlet 110 on both sides, and adjust the opening degree of the first air outlet 110.

[0065] In one alternative implementation, refer to Figure 3 and Figure 4 As shown, a clearance notch 520 is provided at the end of the guide groove 510 to guide the transmission part 310 and prevent it from being misaligned at the end of the guide groove 510. The position and specific shape of the clearance notch 520 can be designed to match the extreme movement position and shape of the transmission part 310, and this embodiment does not impose specific limitations on this.

[0066] Optionally, by designing the guide path of the guide groove 510, it can be designed so that when the slider 300 just starts to slide, it drives the air guide plate 600 to rotate towards a certain side, and at the same time, the baffle plate 200 on that side moves to open the first air outlet 110; it can also be designed so that after the slider 300 slides to a certain distance, the baffle plate 200 starts to move and open the first air outlet 110. That is, the rotation of the air guide plate 600 and the movement of the baffle plate 200 can be synchronous or asynchronous. The specific design can be made according to actual needs, and this embodiment does not make specific limitations on this.

[0067] In one alternative implementation, refer to Figure 1 and Figure 5 As shown, there are multiple air guide plates 600, which are arranged at intervals along the sliding direction of the sliding member 300. The air guide plates 600 can cover the length direction of the second air outlet 120, thereby adjusting the air outlet direction of the entire second air outlet 120, providing a more consistent air outlet effect, and ensuring rapid cooling of areas that require rapid cooling.

[0068] For example, a temperature sensor can be installed on the air duct structure, and the temperature sensor is set in correspondence with the first air outlet 110.

[0069] In one alternative implementation, refer to Figure 1 and Figure 2 As shown, mounting slots 130 for installing temperature sensors are provided on both sides of the air duct plate 100, and the mounting slots 130 are located close to the first air outlet 110. By installing temperature sensors on both sides of the air duct plate 100, temperature differences between different sides can be better detected. This allows the control unit to accurately adjust the angle of the air guide plate 600 and the position of the baffle plate 200 according to the temperature differences in different areas. By using the temperature data from the temperature sensors, positional temperature control is achieved, precisely adjusting the airflow direction and intensity to ensure a uniform and stable internal temperature of the refrigerator, thus improving the user experience.

[0070] In one alternative implementation, refer to Figure 1 and Figure 2 As shown, multiple limiting blocks 140 are provided on the duct plate 100 at positions corresponding to the first air outlet 110. A sliding space 150 is defined between the duct plate 100 and the limiting blocks 140. The baffle plate 200 is slidably disposed in the sliding space 150 to open or close the first air outlet 110.

[0071] For example, the first air outlet 110 can be located at one end of the sliding space 150. Since the connecting rod 500 is rotatably mounted on the air duct plate 100, the corresponding sliding space 150 can be arc-shaped, and the first air outlet 110 can also be arc-shaped accordingly.

[0072] The limiting block 140 ensures the stability of the baffle 200 during sliding, avoiding the problem that the first air outlet 110 cannot be fully opened or closed due to sliding misalignment. Furthermore, the limiting block 140 and the air duct plate 100, which are spaced apart, limit the sliding space 150, which can reduce the weight and space occupied by the entire air duct structure compared to setting an additional separate sliding groove structure.

[0073] The air duct structure provided in this application embodiment includes an air duct plate 100, a baffle plate 200, a sliding member 300, and a driving member 400. The air duct plate 100 forms a cooling air duct and at least two first air outlets 110 communicating with the cooling air duct, with the at least two first air outlets 110 spaced apart. The baffle plate 200 is correspondingly disposed with the first air outlets 110, and the baffle plate 200 is slidably disposed on the first air outlets 110. The sliding member 300 is slidably disposed on the air duct plate 100, and the baffle plate 200 is connected to both sides of the sliding member 300. The driving member 400 is used to drive the sliding member 300 to slide, so as to drive the baffle plate 200 to open one of the first air outlets 110. By setting first air outlets 110 on both sides of the air duct plate 100, the temperature can be adjusted according to the temperature requirements of different areas in the refrigeration equipment. For example, when a certain area is detected to be at a high temperature, the first air outlet 110 of the corresponding area can be opened to assist the air supply through the drive component 400 and the sliding component 300, which can lower the temperature of the area more quickly, reduce the time for the temperature in the refrigeration equipment to reach a uniform and stable state, and thus reduce the energy consumption of the refrigeration process.

[0074] Secondly, embodiments of this application also provide a refrigeration device, as shown in the reference. Figure 8 As shown, the refrigeration equipment includes the air duct structure as described in the above embodiment. The refrigeration equipment can be a refrigerator, freezer, wine cabinet, display case, etc.

[0075] For example, taking a refrigerator as an example, a refrigerator may include a refrigerator compartment, a freezer compartment and a variable temperature compartment, and an air duct structure may be applied to the refrigerator compartment, the freezer compartment or the variable temperature compartment.

[0076] By applying the air duct structure described in the above embodiments, the direction and intensity of the cooling airflow can be automatically adjusted according to the actual temperature distribution inside the refrigeration equipment, so that the cold air can be more evenly distributed throughout the refrigerator space, thereby improving refrigeration efficiency and reducing energy consumption.

[0077] It is understood that since the air duct structure has the beneficial effects of the above embodiments, the refrigeration equipment will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this embodiment will not repeat it.

[0078] Furthermore, the air duct structure can be personalized according to user habits and preferences. For example, users can set the ideal temperature range for different rooms through the control panel or mobile application, and the system will automatically adjust the airflow direction and speed based on these parameters to meet the user's specific needs.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should all be covered within the protection scope of this application.
