Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration, in particular to a refrigeration device. Background Art
[0002] Refrigerators are essential household appliances in our daily lives. Air-cooled refrigerators currently dominate the consumer market due to their inherent resistance to frost buildup. Air-cooled refrigerators require a duct structure to control the circulation of cold air. To increase storage space, some refrigerator duct structures place the supply and return ducts on the same side of the ductwork. This occupies a portion of the ductwork, reducing air supply efficiency and impacting cooling efficiency. Utility Model Content

[0059] The present application provides a refrigeration device, which may be an electrical appliance such as a refrigerator or freezer.
[0060] Please refer to Figure 1 and Figure 2 , Figure 1 This is a first cross-sectional view of the refrigeration equipment according to an embodiment of the present utility model. Figure 2 for Figure 1 The refrigeration device 10 comprises a duct body 100 and a first air duct body 300 .
[0061] A partition 200 is provided within the container body 100, separating the container body 100 into a first chamber 110 and a second chamber 120. By delivering different amounts of cooling to the first and second chambers 110, 120, the first and second chambers 110, 120 are maintained at different storage temperatures, creating multiple storage temperature zones within the same container body 100 to meet the user's storage needs for different items. It is understood that an insulation layer may be provided within the partition 200 to provide insulation and prevent heat transfer between the first and second chambers 110, 120, thereby preventing the temperatures of the first and second chambers 110, 120 from interfering with each other.
[0062] In one embodiment, the cooling temperature of the first chamber 110 is -24°C to -18°C, and the cooling temperature of the second chamber 120 is -18°C to -5°C. The cooling temperature of the first chamber 110 is lower than that of the second chamber 120. The first chamber 110 can be used as a freezer, and the second chamber 120 can be used as a temperature-changing chamber.
[0063] The partition 200 can be arranged along the height direction of the refrigeration device 10 (the body 100) (ie Figure 1 The first chamber 110 and the second chamber 120 are arranged in the horizontal direction, and the first chamber 110 and the second chamber 120 are respectively located on the left and right sides of the partition 200; the partition 200 can also extend along the width direction of the refrigeration device 10 (the body 100), that is, Figure 2 In the left-right direction, the first chamber 110 and the second chamber 120 are arranged in the vertical direction. The first chamber 110 and the second chamber 120 are respectively located on the upper and lower sides of the partition 200, which is not limited in this embodiment of the present application.
[0064] In one embodiment, if Figure 2 As shown, the partition 200 extends along the width direction of the bile body 100, and the first chamber 110 and the second chamber 120 are located on the upper and lower sides of the partition 200. For the convenience of explanation, the chamber located on the lower side of the partition 200 is defined as the first chamber 110, and the chamber located on the upper side of the partition 200 is defined as the second chamber 120.
[0065] The first air duct body 300 is disposed in the first compartment 110. The first air duct body 300 and the rear sidewall of the duct body 100 define a heat exchanger chamber 112. A first storage chamber 111 is formed on the side of the first air duct body 300 facing away from the heat exchanger chamber 112. A heat exchanger 600, such as an evaporator, is disposed within the heat exchanger chamber 112. The first storage chamber 111 is used to store items. For example, storage shelves or drawers can be installed within the first storage chamber 111 to hold items that require low-temperature storage.
[0066] The first air duct body 300 is provided with a first air supply duct 300a, which connects the first storage chamber 111 and the heat exchanger chamber 112. Cold air in the heat exchanger chamber 112 is delivered to the first storage chamber 111 through the first air supply duct 300a, thereby cooling the first storage chamber 111. The first air duct body 300 is also provided with an air guide plate 330, which is disposed at the bottom of the first air duct body 300. The air guide plate 330 and the rear side wall of the air duct body 100 form a second air return duct 331. The second air return duct 331 also connects the first storage chamber 111 and the heat exchanger chamber 112. After heat exchange between the air in the first storage chamber 111 and the stored items, the air can flow into the heat exchanger chamber 112 through the second air return duct 331.
[0067] The refrigeration device 10 further includes a fan 340, which is a power source that provides power to drive air flow. In one embodiment, the fan 340 is disposed in the first air supply duct 300a. An air intake hole (not shown) is provided on the side of the first air duct body 300 facing the heat exchanger chamber 112. The first air supply duct 300a communicates with the heat exchanger chamber 112 through the air intake hole. Specifically, during the operation of the fan 340, a negative pressure is generated in the first air supply duct 300a, and the cold air in the heat exchanger chamber 112 is sucked into the first air supply duct 300a through the air intake hole. Under the continuous action of the fan 340, the cold air is sent to the first storage chamber 111 through the first air supply duct 300a for heat exchange, so that the temperature of the first storage chamber 111 is reduced. The air after heat exchange flows back to the heat exchanger chamber 112 through the second return air duct 331, exchanges heat with the heat exchanger 600 for cooling. The cooled cold air is again sent into the first storage chamber 111 through the first air supply duct 300a under the action of the suction force of the fan 340. This cycle is repeated to realize the air-cooling circulation of the first storage chamber 111.
[0068] Since the heat exchanger chamber 112 is located in the first chamber 110, in order to blow cold air to the second chamber 120, the partition 200 may be provided with an air passage connecting the first chamber 110 and the second chamber 120. Figure 1 The partition 200 is provided with a first air passage 210, which connects the second chamber 120 and the first air supply duct 300a. Under the action of the fan 340, the cold air in the heat exchanger chamber 112 is sent into the second chamber 120 through the first air supply duct 300a and the first air passage 210, thereby cooling the second chamber 120.
[0069] Please refer to Figure 3 , Figure 3This is a second cross-sectional view of the refrigeration device according to an embodiment of the present invention. The partition 200 is further provided with a second air passage 220, which connects the first chamber 110 and the second chamber 120. The first air duct body 300 is provided with a first return air duct 300b. One end of the first return air duct 300b is connected to the heat exchanger chamber 112, and the other end is connected to the second air passage 220. Air in the second chamber 120 can flow back into the heat exchanger chamber 112 through the second air passage 220 and the first return air duct 300b. Specifically, during the cooling process of the second chamber 120, under the action of the fan 340, the cold air in the heat exchanger chamber 112 enters the second chamber 120 through the first air passage 210 for heat exchange, thereby reducing the temperature of the second chamber 120. The air after heat exchange flows back to the heat exchanger chamber 112 through the second air passage 220 and the first return air duct 300b for heat exchange and cooling. The cooled cold air is then sent back to the second chamber 120 through the first air passage 210 under the action of the fan 340. This cycle repeats, thereby achieving an air-cooling cycle for the second chamber 120.
[0070] In the embodiment of the present application, the first air supply duct 300a and the first return air duct 300b are integrally formed and are integrally formed on the first air duct body 300, that is, the first air supply duct 300a and the first return air duct 300b are integrated into the same air duct body. Furthermore, the first air supply duct 300a and the first return air duct 300b are located on the same side of the heat exchanger chamber 112. For ease of explanation, the side closest to the opening of the duct body 100 is defined as the front side, and the side closest to the rear side wall of the duct body 100 is defined as the rear side. Therefore, the first air supply duct 300a and the first return air duct 300b are both located on the front side of the heat exchanger 600.
[0071] By integrating the first return air duct 300b and the first supply air duct 300a into the first duct body 300, that is, integrating the supply air duct of the first compartment 110 and the return air duct of the second compartment 120 into the same duct body, the overall structure of the duct system is simplified, making the entire duct system design more compact, reducing the internal space occupied by the duct body 100, and increasing storage space. Furthermore, by arranging the first return air duct 300b on the front side of the heat exchanger 600, compared to conventional refrigerators that often place the return air duct on the back of the evaporator or embed the return air duct within the refrigerator's foam layer, the first return air duct 300b utilizes the internal space of the first duct body 300, eliminating the need to increase the thickness of the foam layer of the refrigeration device 10 or to reserve installation space on the back side of the heat exchanger 600. This increases the storage space of the first compartment 110, thereby effectively increasing the storage space of the refrigeration device 10.
[0072] Since the first return air duct 300b and the first supply air duct 300a are both located in front of the heat exchanger 600, the first supply air duct 300a cannot be made very large. To reduce the impact on the air supply of the first supply air duct 300a, please refer to Figure 4 , Figure 4 This is a first cross-sectional view of the refrigeration device according to an embodiment of the present invention, taken along section AA. This first cross-sectional view is a cross-sectional view viewed from the front of the first air duct body 300. The refrigeration device 10 further includes an adjustment mechanism 400 disposed between the first air supply duct 300a and the first air return duct 300b. The adjustment mechanism 400 is configured to adjust the volume of the first air supply duct 300a and the first air return duct 300b. When the volume of one increases, the volume of the other decreases.
[0073] That is to say, under the adjustment of the adjustment mechanism 400, the volume change of the first air supply duct 300a is negatively correlated with the volume change of the first return air duct 300b. When the volume of the first air supply duct 300a is increased, the volume of the first return air duct 300b will decrease; correspondingly, when the volume of the first air supply duct 300a is decreased, the volume of the first return air duct 300b will increase. By adjusting the relative volumes of the first air supply duct 300a and the first return air duct 300b through the adjustment mechanism 400, the air supply efficiency and air supply volume of the first air supply duct 300a, as well as the return air efficiency and air return volume of the first return air duct 300b can be changed. Then, when necessary, by increasing the volume of the first air supply duct 300a and reducing the volume of the first return air duct 300b, the volume of the first air supply duct 300a can be increased, the air supply volume and air supply efficiency can be improved, thereby improving the impact of the first return air duct 300b occupying part of the space of the first air duct body 300 on the air supply of the first air supply duct 300a, and improving the cooling efficiency.
[0074] Furthermore, by providing the adjustment mechanism 400, the refrigeration device 10 can adjust the volume of the first air supply duct 300a and the first return air duct 300b according to the specific operating mode, so that the refrigeration device 10 can achieve the optimal cooling effect in the corresponding operating mode. For example, when the refrigeration device 10 is cooling only the first compartment 110, by increasing the volume of the first air supply duct 300a and correspondingly reducing the volume of the first return air duct 300b, the air supply volume to the first compartment 110 can be increased, improving the cooling efficiency, allowing the first compartment 110 to be quickly cooled to the required storage temperature, reducing the cooling time of the first compartment 110, and simultaneously reducing the operating time of the compressor, thereby reducing the energy consumption of the refrigeration device 10. When the refrigeration device 10 cools the first chamber 110 and the second chamber 120 simultaneously, the volume of the first return air duct 300b is reasonably increased, and the volume of the first supply air duct 300a is correspondingly reduced to a certain extent. This ensures that the first chamber 110 has a sufficient supply air volume, while also increasing the return air volume of the first return air duct 300b. This ensures that the supply air to the first chamber 110 and the return air to the second chamber 120 are in a relatively balanced state, so that the temperatures of the first chamber 110 and the second chamber 120 can both be quickly lowered to the required cooling temperature, thereby maximizing the overall cooling efficiency of the refrigeration device 10 in this operating mode.
[0075] To make the volumes of the first air supply duct 300a and the first air return duct 300b adjustable, the wall structure forming the first air supply duct 300a and the first air return duct 300b in the first air duct body 300 can be set as a movable structure or made of deformable material.
[0076] In one embodiment, please continue to refer to Figure 4 The first return air duct 300b and the first supply air duct 300a are arranged adjacent to each other along a first direction, which is parallel to the width of the air duct body 100, i.e., the horizontal direction in the figure. The adjustment mechanism 400 includes a movable partition plate 410. The movable partition plate 410 is disposed between the first supply air duct 300a and the first return air duct 300b. The movable partition plate 410 separates the first supply air duct 300a from the first return air duct 300b. The movable partition plate 410 is movable and switchable between a first position and a second position under the action of an external force. As the movable partition plate 410 moves, the boundary position between the first supply air duct 300a and the first return air duct 300b changes, causing the volumes of the first supply air duct 300a and the first return air duct 300b to change.
[0077] For details, please refer to Figure 5 and Figure 6 , Figure 5 This is a second cross-sectional view of the refrigeration device according to an embodiment of the present invention along section AA. Figure 6This is the third cross-sectional view of the refrigeration device along section AA of an embodiment of the present invention. Both the second and third cross-sectional views are cross-sectional views viewed from the front of the first air duct body 300. When the movable partition plate 410 is in the first position, the volume of the first supply air duct 300a is a first volume S1, and the volume of the first return air duct 300b is a second volume S2. When the movable partition plate 410 is in the second position, the volume of the first supply air duct 300a is a third volume S3, and the volume of the first return air duct 300b is a fourth volume S4. Specifically, the first volume S1 is greater than the third volume S3, and the second volume S2 is smaller than the fourth volume S4.
[0078] Then, when the movable partition plate 410 moves and switches from the first position to the second position, the volume of the first air supply duct 300a decreases, and the volume of the first return air duct 300b increases. When the movable partition plate 410 is in the first position, the first air supply duct 300a is in a state of maximum volume (referring to the state when its own volume is maximum, which does not mean that the volume of the first air supply duct 300a is larger than the volume of the first return air duct 300b, and the same applies to the minimum volume below), and the first return air duct 300b is in a state of minimum volume; when the movable partition plate 410 is in the second position, the first air supply duct 300a is in a state of minimum volume, and the first return air duct 300b is in a state of maximum volume.
[0079] It should be noted that when the movable partition plate 410 is in the first position, the first volume S1 can be greater than the second volume S2, or equal to the second volume S2, or smaller than the second volume S2; similarly, when the movable partition plate 410 is in the second position, the third volume S3 can be greater than the fourth volume S4, or equal to the fourth volume S4, or smaller than the fourth volume S4. The embodiments of the present application do not impose any restrictions on this.
[0080] Please refer to Figure 1 、 Figure 3 and Figure 4 The first air duct body 300 includes a front duct cover 310 and a rear duct cover 320. The front duct cover 310 is connected to the side of the rear duct cover 320 facing away from the heat exchanger chamber 112, that is, the rear duct cover 320 is located between the front duct cover 310 and the heat exchanger 600. The movable partition plate 410 is movably installed between the front duct cover 310 and the rear duct cover 320. The front duct cover 310, the rear duct cover 320, and the movable partition plate 410 define the first supply air duct 300a and the first return air duct 300b.
[0081] Specifically, a slot structure is provided on the air duct front cover 310 or the air duct rear cover 320. The air duct rear cover 320 and the air duct front cover 310 are enclosed by the slot structure to form a cavity for air to flow through. The movable partition plate 410 separates the cavity into the first air supply duct 300a and the first air return duct 300b. In one embodiment, the adjustment mechanism 400 also includes a fixed partition plate 420, which is connected to either the air duct front cover 310 or the air duct rear cover 320 and is located between the first air supply duct 300a and the first air return duct 300b. The movable partition plate 410 is movably connected to the fixed partition plate 420. The movable partition plate 410 and the fixed partition plate 420 together form a partition structure between the first air supply duct 300a and the first air return duct 300b. In one embodiment, the movable partition plate 410 is rotatable relative to the fixed partition plate 420.
[0082] Please refer to Figure 2 The air duct front cover 310 is provided with a first air supply outlet 311 which passes through the air duct along its thickness direction. The first air supply outlet 311 is always located within the range where the first air supply duct 300a is located. In other words, no matter whether the first air supply duct 300a is in a state of maximum volume or a state of minimum volume, the first air supply outlet 311 is always located within the positive projection area of the first air supply duct 300a within the air duct front cover 310. The first air supply duct 300a is connected to the first storage chamber 111 through the first air supply outlet 311, and the cold air in the first air supply duct 300a is blown into the first storage chamber 111 through the first air supply outlet 311.
[0083] The number of the first air outlets 311 can be multiple, so that the cold air can be evenly blown to each area of the first storage chamber 111, thereby achieving uniform cooling of the first storage chamber 111. The drawings of this embodiment only illustrate the example of three first air outlets 311, which is not to be considered as a limitation of the present application.
[0084] Please refer to Figure 3 and Figure 4 The air duct rear cover 320 is provided with a return air outlet 321 extending through the air duct along its thickness. The return air outlet 321 is always located within the range of the first return air duct 300b. In other words, regardless of whether the movable partition plate 410 is in the first position or the second position, the return air outlet 321 is always located within the orthographic projection area of the first return air duct 300b within the air duct rear cover 320. The first return air duct 300b is connected to the heat exchanger chamber 112 through the return air outlet 321. Return air entering the first return air duct 300b from the second chamber 120 flows into the heat exchanger chamber 112 through the return air outlet 321.
[0085] In one embodiment, if Figure 4As shown, the return air outlet 321 is disposed at the end of the air duct rear cover 320 away from the partition 200, that is, the return air outlet 321 is disposed near the bottom end of the air duct rear cover 320. Therefore, the return air needs to flow along the first return air duct 300b to the bottom end of the air duct rear cover 320 and enter the heat exchanger chamber 112, so that the return air has a longer heat exchange distance and a longer heat exchange time, which can improve the return air heat exchange efficiency and the cooling efficiency of the refrigeration device 10.
[0086] In one embodiment, please refer to Figure 7 and Figure 8 , Figure 7 This is a fourth cross-sectional view of the refrigeration device according to an embodiment of the present invention along section AA. Figure 8 This is the fifth cross-sectional view of the refrigeration device along the cross-sectional view AA of the embodiment of the present utility model. The fourth and fifth cross-sectional views are both cross-sectional views viewed from the front side of the first air duct body 300. The air duct rear cover 320 is provided with a first ventilating opening 322 extending through the thickness direction thereof. Figure 7 As shown, when the movable partition plate 410 is in the second position, the first vent 322 is located within the range of the first return air duct 300b. At this time, the first vent 322 is in an open state, so that the first vent 322 connects the first return air duct 300b with the heat exchanger chamber 112. Therefore, the return air entering the first return air duct 300b from the second chamber 120 can enter the heat exchanger chamber 112 through the return air outlet 321 and the first vent 322. This increases the air outlet area of the first return air duct 300b and improves the return air efficiency. Moreover, the first vent 322 and the return air outlet 321 can be set at different positions, so that the return air in the first return air duct 300b not only flows into the heat exchanger chamber 112 from the bottom of the first air duct body 300, but can also flow into the heat exchanger chamber 112 from other positions through the first vent 322, so that the return air can contact and exchange heat with a larger area of the heat exchanger 600, thereby improving the utilization rate of the heat exchanger 600 and further improving the heat exchange efficiency of the return air.
[0087] like Figure 8 As shown, when the movable partition plate 410 is in the first position, the first vent 322 is located within the range of the first air supply duct 300a. At this time, the first vent 322 is in a closed state to prevent the cold air in the first air supply duct 300a from entering the heat exchanger chamber 112 through the first vent 322 and affecting the air supply volume.
[0088] In one embodiment, please continue to refer to Figure 7 and Figure 8The adjustment mechanism 400 further includes a first shielding member 430 connected to the movable partition plate 410. The first shielding member 430 is driven by the movable partition plate 410 to move to cover or reveal the first vent 322. When the movable partition plate 410 is in the first position, the first shielding member 430 covers the first vent 322, placing the first vent 322 in a closed state. When the movable partition plate 410 is in the second position, the first shielding member 430 reveals the first vent 322, placing the first vent 322 in an open state.
[0089] In this embodiment, the first shielding member 430 is connected to the movable partition plate 410. The movable partition plate 410 drives the first shielding member 430 to move together, eliminating the need for a separate drive device for the first shielding member 430. This reduces the internal space occupied by the first air duct body 300 and simplifies the structure and assembly of the first air duct body 300, facilitating production. Furthermore, the lack of a drive device for the first shielding member 430 reduces the risk of failure and improves reliability.
[0090] Specifically, the first shielding member 430 can be connected to the side of the movable partition plate 410 near the air duct rear cover 320, and the first shielding member 430 abuts the inner surface of the air duct rear cover 320. The first shielding member 430 can be configured as a thin plate, which not only reduces the space occupied within the first return air duct 300b or the first supply air duct 300a, but also avoids blocking the flow of air. Furthermore, the first shielding member 430 abuts the inner surface of the air duct rear cover 320 to ensure that when the movable partition plate 410 is in the first position, the first shielding member 430 can tightly cover the first vent 322 to prevent air leakage.
[0091] In one embodiment, there is at least one first vent 322 , and the position of the at least one first vent 322 is higher than the return air outlet 321 , that is, the at least one first vent 322 is arranged on the upper side of the return air outlet 321 .
[0092] As can be understood, the temperature of the return air is generally higher than that of the heat exchanger 600. After entering the heat exchanger chamber 112, the return air exchanges heat with the heat exchanger 600, melting some of the frost condensed on the heat exchanger 600 and achieving a certain defrosting effect. Specifically, when the movable partition plate 410 is in the second position, the return air in the first return air duct 300b enters the heat exchanger chamber 112 through the first vent 322 and the return air outlet 321. Since the first vent 322 is positioned above the return air outlet 321 in this embodiment, the return air entering the heat exchanger chamber 112 through the first vent 322 contacts and exchanges heat with the upper portion of the heat exchanger 600, effectively defrosting the upper portion of the heat exchanger 600. This improves the defrosting effect on the upper portion of the heat exchanger 600 caused by the return air from the bottom being cooled, thereby enhancing the defrosting capacity of the heat exchanger 600 and further improving the cooling effect of the refrigeration device 10.
[0093] When there are multiple first ventilation openings 322, the multiple first ventilation openings 322 are arranged along the second direction, which is parallel to the height direction of the gallbladder body 100. Figure 7 For example, the second direction is the vertical direction in the figure.
[0094] Please refer to Figure 9 and Figure 10 , Figure 9 This is a sixth cross-sectional view of the refrigeration device according to an embodiment of the present invention along section AA. Figure 10 This is the seventh cross-sectional view of the refrigeration device along the cross-sectional view AA of the embodiment of the present utility model, wherein the sixth and seventh cross-sectional views are cross-sectional views viewed from the rear side of the first air duct body 300. The air duct front cover 310 is provided with a second ventilating opening 312 extending through the thickness direction thereof, as shown in FIG. Figure 9 As shown, when the movable partition plate 410 is in the first position, the second vent 312 is located within the range of the first air supply duct 300a. At this time, the second vent 312 is in the open state, so that the second vent 312 connects the first air supply duct 300a with the first storage chamber 111. Therefore, the cold air entering the first air supply duct 300a from the heat exchanger chamber 112 can enter the first storage chamber 111 through the first air supply duct 311 and enter the first storage chamber 111 through the second vent 312. This increases the air outlet area of the first air supply duct 300a and improves air supply efficiency. Moreover, the second vent 312 and the first air supply duct 311 can be arranged at different positions, so that the cold air in the first air supply duct 300a is delivered to the first storage chamber 111 from different positions of the air duct front cover 310, further improving the uniformity of air supply and making it easier to achieve uniform cooling in the first storage chamber 111.
[0095] like Figure 10As shown, when the movable partition plate 410 is in the second position, the second vent 312 is located within the range of the first return air duct 300b. At this time, the second vent 312 is in a closed state to prevent the return air in the first return air duct 300b from entering the first storage chamber 111 through the second vent 312, thereby avoiding affecting the temperature in the first storage chamber 111.
[0096] In one embodiment, please continue to refer to Figure 9 and Figure 10 The adjustment mechanism 400 further includes a second shielding member 440 connected to the movable partition plate 410. The second shielding member 440 moves under the influence of the movable partition plate 410 to cover or reveal the second vent 312. When the movable partition plate 410 is in the first position, the second shielding member 440 reveals the second vent 312, placing the second vent 312 in an open state. When the movable partition plate 410 is in the second position, the second shielding member 440 covers the second vent 312, placing the second vent 312 in a closed state.
[0097] In this embodiment, the second shielding member 440 is connected to the movable partition plate 410. The movable partition plate 410 drives the second shielding member 440 to move together, eliminating the need for a separate drive device for the second shielding member 440. This reduces the internal space occupied by the first air duct body 300 and simplifies the structure and assembly of the first air duct body 300, facilitating production. Furthermore, the lack of a drive device for the second shielding member 440 reduces the risk of failure and improves reliability.
[0098] Specifically, the second shielding member 440 can be connected to the side of the movable partition plate 410 near the air duct front cover 310, and the second shielding member 440 abuts the inner surface of the air duct front cover 310. The second shielding member 440 can be configured as a thin plate, which not only reduces the space occupied within the first return air duct 300b or the first supply air duct 300a, but also avoids blocking the flow of air. Furthermore, the second shielding member 440 abuts the inner surface of the air duct front cover 310 to ensure that when the movable partition plate 410 is in the second position, the second shielding member 440 can tightly cover the second vent 312 to prevent air leakage.
[0099] In one embodiment, the number of second vents 312 can be multiple, with the multiple second vents 312 arranged along the second direction. For example, in some large refrigerators, the first storage compartment 111 is relatively large. By providing multiple second vents 312, the cold air in the first air supply duct 300a is blown into the first storage compartment 111 through the multiple first air supply ducts 311 and the multiple second vents 312, further increasing the air outlet area of the first air supply duct 300a and improving the cooling effect on the first storage compartment 111.
[0100] Please refer to Figure 4 The adjustment mechanism 400 further includes a driving member 450, which is mounted on the fixed partition plate 420 and connected to the movable partition plate 410. The driving member 450 is used to drive the movable partition plate 410 to rotate and switch between the first position and the second position. The driving member 450 can be a micro motor.
[0101] Please refer to Figure 1 The refrigeration device 10 further includes a damper 700 , which is disposed in the first air passage 210 . The damper 700 is configured to open or block the first air passage 210 .
[0102] When the refrigeration device 10 needs to cool the second chamber 120, the damper 700 is driven to open the first air passage 210, allowing the cold air in the first air supply duct 300a to enter the second chamber 120 through the first air passage 210. Specifically, the refrigeration device 10 also includes a second air duct body 500. The second air duct body 500 is disposed in the second chamber 120 and is provided with a second air supply duct 510. The second air supply duct 510 is connected to the first air passage 210 and is further provided with a second air supply port 520. Therefore, when cooling the second chamber 120, the cold air in the heat exchanger 600 is sequentially delivered into the second chamber 120 through the first air supply duct 300a, the first air passage 210, the second air supply duct 510, and the second air supply port 520.
[0103] Because the opening and closing of the damper 700 corresponds to whether the second chamber 120 is being cooled, the opening and closing of the damper 700 can be controlled in conjunction with the driver 450. In one embodiment, when the damper 700 opens the first air passage 210, the refrigeration device 10 is cooling the second chamber 120, and the driver 450 drives the movable partition plate 410 to the second position, allowing the first return air duct 300b to reach its maximum volume. When the damper 700 blocks the first air passage 210, the refrigeration device 10 stops cooling the second chamber 120, and the driver 450 drives the movable partition plate 410 to the first position, allowing the first supply air duct 300a to reach its maximum volume.
[0104] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
