Description

TECHNICAL FIELD

[0001] The utility model relates to the field of home appliances, in particular to a damper device and refrigeration equipment. BACKGROUND

[0002] With the continuous development of the home appliance market, frost-free air-cooled refrigeration equipment gradually becomes the first choice of consumers because it has automatic defrosting function, avoiding the trouble of regular manual defrosting. This kind of refrigeration equipment generally uses electric damper to control the opening and closing of refrigeration air duct, so as to realize the transportation of cold air between different storage spaces, or to control the flow and temperature distribution of cold air by adjusting the opening and closing state of the damper in the air duct.

[0003] In the traditional design of electric damper, the outer frame and the gear box are usually of one-piece structure, which cannot adapt to different use requirements. For example, when a single damper is needed, a new damper structure must be redesigned and manufactured. In addition, due to the one-piece structure of the electric damper, when developing different size dampers, a larger mold needs to be newly opened for each size, and these molds are usually not universal. This not only increases the manufacturing cost, but also leads to the extension of the production cycle, and is not conducive to the flexibility and adaptability of damper design. SUMMARY

DETAILED DESCRIPTION

[0039] Example embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While example embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0040] It is to be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has", "having" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order in which they are described, unless specifically identified as an order dependent step. It is also to be understood that additional or alternative steps can be employed.

[0041] Although the terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms when used in the singular or plural herein do not imply a sequence or order to the elements, but to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below can later be referred to as a second element, component, region, layer or section without departing from the teachings of the example embodiments.

[0042] For ease of description, spatial relative terms can be used herein to describe the relationship of one element or feature to another element or feature as shown in the drawings, such as "inner", "outer", "inside", "outside", "lower", "below", "upper", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings.

Therefore, the example term "below" can include both the above and below orientations.

[0043] As shown in Figures 1 to 14 According to the embodiment of the present application, a damper device 100 is provided, which specifically includes a damper mechanism and a driving mechanism 20. The damper mechanism includes a door frame and a door plate. An opening is defined on the door frame. The door plate is pivotally connected to the door frame to open or close the opening. The damper mechanism is detachably connected to the driving mechanism 20. The driving mechanism 20 includes a driving shaft 22. The driving shaft 22 is detachably connected to the door plate. The driving shaft 22 drives the door plate to pivot relative to the door frame.

[0044] According to the damper device 100 of the present application, by designing the damper mechanism and the driving mechanism 20 to be detachably connected, users or manufacturers can conveniently replace or adjust the damper device 100 according to actual needs. This design improves the flexibility and adaptability of the damper device 100, better meets the adjustment of different size or functional requirements, and avoids the inconvenience caused by fixed integrated structure. Further, since the damper mechanism and the driving mechanism 20 adopt the design of detachable connection, the combination of the driving mechanism 20 and the damper mechanism can be flexibly selected in different application scenarios, reducing the demand for customized design and mold, thereby reducing production cost and manufacturing cycle.

[0045] In some embodiments, the driving mechanism 20 comprises a housing 21 which is detachably connected with the door frame. The detachable connection of the housing 21 and the door frame provides higher design flexibility, which can easily replace or adjust the configuration of the driving mechanism 20 and the damper according to different requirements. Different sizes, models or functional requirements of the damper device 100 can be achieved by adjusting the combination of the housing 21 and the door frame, without the need to redesign the entire damper structure, enhancing the adaptability of the product.

[0046] Specifically, the housing 21 and the door frame are connected by a bolt 30 structure. In a specific embodiment, two spaced apart screw holes 2111 are formed on the side surface of the housing 21, which are parallelly arranged and have sizes and positions matched with the screw holes 2111 on the door frame. The screw holes 2111 on the door frame are accurately connected with the screw holes 2111 on the housing 21 to ensure that the bolt 30 can smoothly pass through and connect the housing 21 and the door frame. After aligning the screw holes 2111 of the door frame and the housing 21, a bolt 30 with appropriate length and diameter is selected to pass through the door frame and the housing 21 through the screw holes 2111 in sequence. The bolt 30 is locked by tightening to firmly connect the door frame and the housing 21 together. Lock nuts or washers can be used according to actual needs to ensure that the bolt 30 does not loosen during long-term use. To enhance the firmness of the connection, reinforcing rings or reinforcing ribs can be added at the screw hole 2111 position to prevent damage to the screw hole 2111 due to long-term stress. At the same time, the use of lock nuts or plastic washers can improve the reliability of the bolt 30 connection and prevent loosening due to vibration or external forces.

[0047] Specifically, the housing 21 and the door frame are connected by a buckle structure. In a specific embodiment, the bottom of the housing 21 is designed with side-by-side and protruding clamping blocks 2112, and the shape and size of the clamping blocks 2112 are matched with the buckles 112 of the door frame. The bottom of the door frame is provided with buckles 112 matched with the clamping blocks 2112 of the housing 21. The buckles 112 are designed to accurately connect with and tightly combine with the clamping blocks 2112, to ensure that when the door frame approaches the housing 21, the buckles 112 can firmly hold the clamping blocks 2112 to form a stable connection. The buckles 112 on the door frame are connected with the clamping blocks 2112 at the bottom of the housing 21 when the door frame approaches the housing 21. Due to the reasonable design of the shape and size of the buckles 112 and the clamping blocks 2112, the buckles 112 will be clamped into the clamping blocks 2112 and firmly locked during the approach of the door frame to the housing 21. This process is achieved through elastic deformation, and the buckles 112 will slightly deform when they contact the clamping blocks 2112, to ensure that the clamping blocks 2112 and the buckles 112 can be firmly combined to prevent the door frame from separating from the housing 21.

[0048] Understandably, the housing 21 and the door frame can be connected simultaneously using both a snap-fit ​​structure and a bolt 30 structure. This dual connection method of snap-fit ​​and bolt 30 effectively improves the strength of the connection between the housing 21 and the door frame. While the snap-fit ​​structure provides a quick and convenient connection, the bolt 30 structure, as a supplement, provides stronger fixing force, ensuring a more stable and reliable connection between the door frame and the housing 21 during long-term use, especially under high vibration or strong external forces.

[0049] Specifically, a through hole 2113 is provided on the housing 21, and the drive shaft 22 passes through the through hole 2113. The part of the drive shaft 22 located inside the housing 21 is connected to the drive assembly 24, and the part of the drive shaft 22 located outside the housing 21 is connected to the door panel for transmission.

[0050] In some embodiments, there are two damper mechanisms, namely a first damper mechanism 10 and a second damper mechanism 40 arranged side by side. The first damper mechanism 10 and the second damper mechanism 40 are respectively located on opposite sides of the drive mechanism 20, and the drive mechanism 20 is detachably connected to the first damper mechanism 10 and the second damper mechanism 40. The drive mechanism 20 is used to drive the first damper mechanism 10 and the second damper mechanism 40 to open and close. Further, the drive mechanism 20 can sequentially drive the first damper mechanism 10 and the second damper mechanism 40 to open and close, so that the damper device 100 has a first state (e.g., Figure 4 As shown), the second state (as shown) Figure 5 As shown), the third state (as shown) Figure 6 (as shown) and the fourth state (as shown) Figure 7 (As shown). In the first state, the first damper mechanism 10 is open and the second damper mechanism 40 is open; in the second state, the first damper mechanism 10 is closed and the second damper mechanism 40 is open; in the third state, the first damper mechanism 10 is closed and the second damper mechanism 40 is closed; in the fourth state, the first damper mechanism 10 is open and the second damper mechanism 40 is closed. Through precise control of these four damper states, the damper device 100 can flexibly adjust the airflow in each storage space of the refrigeration equipment, optimizing the distribution of cold air and temperature uniformity. For example, in the first state, both the first damper mechanism 10 and the second damper mechanism 40 are open, increasing the cold air flow and effectively maintaining a balanced temperature within the refrigeration equipment, preventing excessively high or low temperatures in any storage space, and improving the refrigeration efficiency of the equipment.

[0051] like Figures 8 to 11As shown, further, the driving mechanism 20 comprises a driving assembly 24, a first driving shaft 221 and a second driving shaft 222, the first damper mechanism 10 comprises the first door plate 12, the second damper mechanism 40 comprises the second door plate 42, the first door plate 12 is in driving connection with the first driving shaft 221, the second door plate 42 is in driving connection with the second driving shaft 222, the first driving shaft 221 and the second driving shaft 222 are respectively in driving connection with the driving assembly 24, and the driving assembly 24 drives the damper device 100 to switch between the first state, the second state, the third state and the fourth state.

[0052] In some embodiments, the driving assembly 24 can comprise two motors 25 and two gear sets respectively in one-to-one driving connection with the two motors 25. One of the gear sets is in driving connection with the first driving shaft 221, and the other gear set is in driving connection with the second driving shaft 222. For the convenience of description, the two motors 25 are respectively referred to as a first motor and a second motor, the gear set in driving connection with the first motor is a first gear set, and the gear set in driving connection with the second motor is a second gear set. When it is necessary to adjust the damper state, the control system 23 starts the first motor and the second motor respectively. The first motor drives the first driving shaft 221 through the first gear set, and the second motor drives the second driving shaft 222 through the second gear set. The rotation of the two motors 25 transmits power through the gear sets to realize precise control of the damper device 100. This scheme can accurately control the opening and closing states of the two dampers through the two motors 25 and the mutually independent gear sets, and supports separate or synchronous adjustment. Users can accurately adjust the dampers according to the needs, optimize the air distribution of the refrigeration equipment, and ensure the uniform temperature of each storage space.

[0053] As shown in FIG. 1, the damper device 100 comprises a first damper mechanism 10 and a second damper mechanism 40, and the first damper mechanism 10 and the second damper mechanism 40 are respectively arranged on the left side and the right side of the refrigeration equipment 1. The first damper mechanism 10 comprises a first door plate 12, and the second damper mechanism 40 comprises a second door plate 42. The first door plate 12 and the second door plate 42 are respectively arranged on the left side and the right side of the refrigeration equipment 1, and the first door plate 12 and the second door plate 42 are respectively in driving connection with the first driving shaft 221 and the second driving shaft 222. Figures 11 to 13As shown, in some embodiments, the driving assembly 24 includes a driving gear 246, a driven gear 245, and a motor 25, the motor 25 is drivingly connected with the driving gear 246, the driven gear 245 is connected with the first driving intermittent gear 241, and the driving gear 246 and the driven gear 245 are in meshing engagement. First of all, the motor 25 is the core power source of the driving assembly 24, which provides power for the whole system through the rotating output shaft. The motor 25 is installed through bearings to ensure its smooth operation. The motor 25 has two modes of forward rotation and reverse rotation, the driving gear 246 is directly connected to the output shaft of the motor 25, and the power of the motor 25 is transmitted to the driven gear 245. The number of teeth and the size of the driving gear 246 are designed according to the transmission ratio to match the requirements of the driven gear 245. The driven gear 245 is in meshing engagement with the driving gear 246 for receiving the power transmitted by the driving gear 246. The shaft of the driven gear 245 is connected to the first driving intermittent gear 241 to further transmit power to the first driving intermittent gear 241. The transmission design of the driving gear 246 and the driven gear 245 improves the power transmission efficiency, ensuring that the power of the motor 25 can be smoothly transmitted to the first driving intermittent gear 241, avoiding power loss.

[0054] It can be understood that the driving assembly 24 further includes a first driven intermittent gear 243, a first driving intermittent gear 241, a second driven intermittent gear 244, and a second driving intermittent gear 242, wherein the first driven intermittent gear 243 is arranged on the first driving shaft 221, the second driven intermittent gear 244 is arranged on the second driving shaft 222, the first driving intermittent gear 241 is in driving cooperation with the first driven intermittent gear 243 and the driven gear 245 respectively to drive the first door panel 12 to pivot, the second driving intermittent gear 242 is in driving cooperation with the second driven intermittent gear 244 and the first driving intermittent gear 241 respectively to drive the second door panel 42 to pivot, and the first driving intermittent gear 241 can drive the second driving intermittent gear 242 to rotate. The first driving shaft 221 is drivingly connected with the first driven intermittent gear 243, transmits power through the first driving intermittent gear 241 to realize the rotation of the first door panel 12, and the second driving shaft 222 is drivingly connected with the second driven intermittent gear 244, transmits power through the second driving intermittent gear 242 to realize the rotation of the second door panel 42.

[0055] Specifically, since the first driving intermittent gear 241 and the second driving intermittent gear 242 are structurally identical, and the first driven intermittent gear 243 and the second driven intermittent gear 244 are structurally identical, only the transmission matching relationship between the first driving intermittent gear 241 and the first driven intermittent gear 243 is described here. The first driving intermittent gear 241 is a circular gear with a partial gear tooth and a sliding matching part, wherein the gear part is located in a local area of the circumferential surface of the circular gear, forming a toothed area, which is used to mesh with the first driven intermittent gear 243. The arc length of the toothed area determines the period of intermittent meshing. The number of teeth and the tooth shape of the gear are matched with the driven intermittent gear to ensure reliable power transmission when meshing. The sliding matching part is located in the remaining part of the circumferential surface of the circular gear, which is used to contact the limiting matching part of the first driven intermittent gear 243. The sliding matching part is usually designed as a smooth circular arc surface or a sector arc surface, which does not have a transmission function. The sliding matching part and the limiting matching part function to guide the smooth rotation of the first driving intermittent gear 241, while preventing the first driven intermittent gear 243 from being forced to rotate. The first driven intermittent gear 243 is a structure with an arc-shaped gear tooth, which is used to mesh with the toothed area of the first driving intermittent gear 241. The number of teeth of the arc-shaped gear is matched with the number of teeth of the driving intermittent gear, and the tooth shape corresponds to the driving gear 246. The length of the arc-shaped gear is usually corresponding to the length of the toothed area of the driving intermittent gear, ensuring accurate intermittent meshing. The matching relationship between the first driving intermittent gear 241 and the first driven intermittent gear 243 is that when the first driving intermittent gear 241 rotates to its toothed area aligning with the arc-shaped tooth of the first driven intermittent gear 243, the two begin to mesh. Power is transmitted from the first driving intermittent gear 241 to the first driven intermittent gear 243, driving the first driving shaft 221 and the door panel connected thereto to rotate. When the gear part of the first driving intermittent gear 241 moves away from the arc-shaped tooth of the driven gear 245, the gear enters the sliding matching state. The sliding matching part of the first driving intermittent gear 241 contacts the limiting matching part of the first driven intermittent gear 243, ensuring the smooth rotation of the first driving intermittent gear 241, but not transmitting power.

[0056] As Figure 14As shown, further, the circumferential two sides of the arc-shaped gear teeth of the first driven intermittent gear 243 are respectively provided with a first half-tooth area 2431 and a second half-tooth area 2432, the first half-tooth area 2431 and the second half-tooth area 2432 are smooth transition areas and the two sides in the circumferential direction have limiting teeth, that is, constitute a limiting matching part, which is matched with the sliding matching part of the first driving intermittent gear 241 to realize stable sliding connection. At the same time, when the first driving intermittent gear 241 contacts the first half-tooth area 2431 of the first driven intermittent gear 243, the limiting teeth on one side of the first half-tooth area 2431 abut against the side surface of the first driving intermittent gear 241 to limit the first driven intermittent gear 243. Similarly, when the first driving intermittent gear 241 contacts the second half-tooth area 2432 on the other side, the limiting teeth on one side of the second half-tooth area 2432 abut against the side surface of the first driving intermittent gear 241 to also limit the first driven intermittent gear 243.

[0057] Further, the first driving intermittent gear 241 and the second driving intermittent gear 242 are coaxially arranged, and the end face of the first driving intermittent gear 241 facing one end of the second driving intermittent gear 242 is provided with a protrusion 2411, and the end face of the second driving intermittent gear 242 facing one end of the first driving intermittent gear 241 is provided with a stop block 2421 located on the rotation track of the protrusion 2411, and the protrusion 2411 and the stop block 2421 cooperate to enable the second driving intermittent gear 242 to be reversely rotated under the drive of the first driving intermittent gear 241.

[0058] As shown in FIG. 1, Figure 11 As shown in FIG. 1, Figure 4 As shown in FIG. 1,

[0059] From the first state to the second state, the first driving intermittent gear 241 rotates clockwise, and the toothed area engages the first driven intermittent gear 243, so that the first driven intermittent gear 243 rotates counterclockwise to drive the first damper mechanism 10 to close. At this time, the first driving intermittent gear 241 idles, the protrusion 2411 has not contacted the stop block 2421 of the second driving intermittent gear 242, and the second damper mechanism 40 remains in the open state. At this time, the sliding matching part of the first driving intermittent gear 241 abuts against the first half-tooth area 2431 of the first driven intermittent gear 243.

[0060] From the second state to the third state, the first driving intermittent gear 241 continues to rotate clockwise, the first side of the protrusion 2411 contacts the first side of the block 2421 of the second driving intermittent gear 242, and power is transmitted to make the second driving intermittent gear 242 rotate clockwise. The second driving intermittent gear 242 drives the second driven intermittent gear 244 to rotate counterclockwise, and the second air door mechanism 40 is closed. At this time, the two air door mechanisms are simultaneously in the closed state.

[0061] From the third state to the fourth state, the first driving intermittent gear 241 rotates counterclockwise, the toothed area is engaged with the first driven intermittent gear 243, and the first driven intermittent gear 243 is driven to rotate clockwise, the first air door mechanism 10 is opened, and the sliding fit part of the first driving intermittent gear 241 is in abutment with the second half tooth area 2432 of the first driven intermittent gear 243. However, the protrusion 2411 has not contacted the block 2421 of the second driving intermittent gear 242.

[0062] From the fourth state to the first state, the first driving intermittent gear 241 continues to rotate counterclockwise, the second side of the protrusion 2411 contacts the second side of the block 2421 of the second driving intermittent gear 242, and power is transmitted to make the second driving intermittent gear 242 rotate counterclockwise. The second driving intermittent gear 242 is engaged with the second driven intermittent gear 244, and the second driven intermittent gear 244 is driven to rotate clockwise, and the second air door mechanism 40 is opened. At this time, the two air door mechanisms are simultaneously in the opened state.

[0063] It can be understood that, through the linkage design of the protrusion 2411 and the block 2421, the opening and closing of the air door can be realized at different times and in different sequences to meet the cold air demand of different storage spaces.

[0064] Further, there are transition states between the first state and the second state, the second state and the third state, the third state and the fourth state, and the fourth state and the first state. Taking the transition state between the first state and the second state as an example, from the first state to the second state, the first driving intermittent gear 241 rotates clockwise, and the toothed area is engaged with the first driven intermittent gear 243, so that the first driven intermittent gear 243 rotates counterclockwise, and the first air door mechanism 10 is driven to be in a half-open state. The specific way is that the toothed area of the first driving intermittent gear 241 is always engaged with the first driven intermittent gear 243, which means that the circumferential sliding fit part of the first driving intermittent gear 241 does not abut with the first half tooth area 2431 of the first driven intermittent gear 243. At this time, the first driving intermittent gear 241 does not rotate, and the first driven intermittent gear 243 does not rotate due to the engagement with the first driving intermittent gear 241, resulting in that the first air door mechanism 10 can be in a half-open state.

[0065] Further, the driving mechanism 20 further comprises a control system 23 electrically connected with the motor 25, for adjusting the rotating direction and operating state of the motor 25. The control system 23 can realize the forward rotation or reverse rotation of the motor 25 by applying a positive voltage or a negative voltage to the motor 25.

[0066] It can be understood that the first air door mechanism 10 has a first opening 111, and the second air door mechanism 40 has a second opening 411, wherein the first opening 111 of the first air door mechanism 10 and the second opening 411 of the second air door mechanism 40 have a difference in area. The opening areas of the first air door mechanism 10 and the second air door mechanism 40 have a difference, so that the air flow can be distributed according to the requirements of the storage space. For example, a larger air door opening area can deliver more cold air to meet the refrigeration requirements of a large-capacity storage space, and a smaller air door opening area can reduce the amount of cold air delivered to avoid waste of energy. This difference design can accurately match the refrigeration requirements of the storage space and improve the efficiency of cold air utilization inside the refrigeration equipment.

[0067] In some embodiments, the shell 21 adopts a split structure, which is divided into a first shell 211 and a second shell 212, and the first shell 211 and the second shell 212 are connected through a buckle structure. The split structure design allows the shell 21 to be quickly disassembled when needed, facilitating the maintenance and replacement of internal components and reducing maintenance costs.

[0068] In some embodiments, the first door frame 11 of the first air door mechanism 10 and the second door frame 41 of the second air door mechanism 40 are also connected through a buckle structure. Specifically, the edge of the first air door mechanism 10 is provided with a buckle groove, and the edge of the second air door mechanism 40 is provided with a buckle block. When the edge of the first air door mechanism 10 and the edge of the second air door mechanism 40 are fitted, the buckle block and the buckle groove are locked with each other. The buckle structure provides reliable mechanical locking effect, which can maintain the stable connection of the first door frame 11 and the second door frame 41 during long-term use, avoiding loosening or falling off.

[0069] In some embodiments, the end of the drive shaft 22 connected to the door panel is provided with a limiting block, and the door panel is provided with a limiting slot at a position matched with the limiting block, and the limiting block is accommodated in the limiting slot to enable the drive shaft 22 to drive the door panel to rotate. Specifically, the end of the drive shaft 22 is provided with a limiting block. The limiting block is designed in a rectangular, square or other geometric shape to ensure that the torque can be firmly transmitted when matched with the limiting slot of the door panel. The limiting block is mounted by being integrally formed with the drive shaft 22 or being fastened to the drive shaft 22 to ensure the stability of the limiting block. One side of the door panel is provided with a limiting slot, and the limiting slot is matched with the limiting block in shape and size to accommodate the limiting block and transmit power. The depth and width of the limiting slot are accurately designed to ensure that the limiting block can be smoothly inserted and to avoid loosening or being too tight to cause jamming. The drive shaft 22 is inserted into the limiting slot on the door panel through the limiting block to form a mechanical connection. When the drive shaft 22 rotates, the limiting block drives the limiting slot to rotate synchronously, thereby realizing the opening and closing actions of the door panel.

[0070] In some embodiments, a sink groove is arranged on the side of the door frame facing the door panel, and the sink groove is composed of an inner circumferential wall of the door frame and a flat surface with an opening. When the door panel closes the opening, the door panel is accommodated in the sink groove, and the door panel is attached to the flat surface with the opening and closes the opening. The sink groove design embeds the door panel in the door frame, increasing the rigidity and strength of the damper mechanism. Even in the case of high-frequency switching or long-term use, the door panel and the door frame can still maintain close cooperation to avoid loosening or deformation.

[0071] In some embodiments, a flexible sealing strip is arranged around the opening. When the door panel closes the opening, the flexible sealing strip tightly contacts the edge of the door panel to form an efficient seal with the door panel, preventing cold air from leaking from the opening. At the same time, the flexible material of the sealing strip can buffer the impact force when the door panel is closed, reducing the collision noise between the door panel and the door frame. This improves the quiet performance of the refrigeration equipment and improves the user experience.

[0072] In some embodiments, a soft foam is arranged on the side of the door panel facing the opening. The soft foam has a moderate thickness that can ensure sealing without hindering the normal opening and closing of the door panel. The soft foam can fill the small gaps between the door panel and the opening when the door panel contacts the opening, forming a complete sealing structure to effectively prevent cold air from leaking and hot air from entering. At the same time, the soft foam can absorb and alleviate the impact noise when the door panel is closed, improving the quiet performance of the refrigeration equipment and optimizing the user experience.

[0073] The present embodiment also provides a refrigeration equipment comprising the damper device 100 described above. The refrigeration equipment further comprises a shell, a refrigeration chamber, a freezing chamber, a refrigeration system and a temperature control system. The damper device 100 is arranged at a partition or an air duct between the refrigeration chamber and the freezing chamber. Through the damper controller, the damper can adjust the flow or closure of cold air according to the change of the temperature in the refrigeration equipment to ensure that the refrigeration chamber and the freezing chamber are respectively at the set temperature.

[0074] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
