Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a damper structure and an air handling device. Background Technology

[0002] Currently, some of the dampers in existing air handling units are open. When the air handling unit is not in operation, open dampers cannot prevent outdoor mosquitoes, hot summer air, and cold winter air from entering the room.

[0003] Therefore, the related technology provides a fresh air device and an air conditioner. The fresh air device includes: a housing having a receiving cavity and a fresh air outlet that are interconnected; and a blocking part disposed in the receiving cavity, the blocking part being movably disposed along the extending direction of the fresh air outlet, the blocking part having a closed position and an open position, wherein when the blocking part is in the closed position, the blocking part blocks the fresh air outlet, and when the blocking part is in the open position, the blocking part and the fresh air outlet are spaced apart to avoid obstructing the fresh air outlet.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The sealing part is movably installed along the extension direction of the fresh air outlet, that is, the sealing part moves toward or away from the receiving cavity, which results in the sealing part occupying a large space, thereby increasing the volume of the fresh air device.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a damper structure and an air handling device to solve the problem of large space requirements for the sealing part in related technologies.

[0009] According to a first aspect of the present invention, a damper structure is provided, comprising: a housing defining an air vent; a cover plate covering the air vent, the cover plate having a first notch communicating with the air vent; and a baffle plate rotatably connected to the housing and / or the cover plate, and capable of rotating relative to the cover plate between a closed position covering the first notch and an open position opening the first notch.

[0010] Optionally, the cover plate includes: a plate body, which is provided corresponding to the air vent; a side wall, which is provided on the side of the plate body facing the air vent, one end of the side wall is connected to the plate body, and the other end of the side wall abuts against the housing; wherein, the first notch is provided in the side wall.

[0011] Optionally, the main body of the panel protrudes outward from the outside of the air vent.

[0012] Optionally, there may be multiple first notches, which are arranged sequentially along the circumference of the sidewall.

[0013] Optionally, the baffle is fitted over the outside of the cover plate; or, the cover plate is fitted over the outside of the baffle.

[0014] Optionally, the baffle is provided with a second notch. In the open position, the second notch corresponds to and is connected to the first notch. In the closed position, the second notch is offset from the first notch.

[0015] Optionally, the housing is provided with a guide engagement portion, and the baffle includes: a cover portion, which covers the first notch in the closed position; and a guide portion, which is connected to the cover portion and engages with the guide engagement portion to guide the baffle relative to the cover plate between the closed position and the open position.

[0016] Optionally, the housing is provided with a limiting engagement part, and the baffle is provided with a limiting part. The limiting part and the limiting engagement part cooperate to limit the range of motion of the baffle relative to the cover plate.

[0017] Optionally, the damper structure further includes: a drive element; a gear, which is driven to connect with the drive element, and the baffle is provided with gear teeth that mesh with the gear. The drive element drives the gear to rotate, and the gear meshes with the gear teeth to drive the baffle to rotate relative to the cover plate between a closed position and an open position.

[0018] According to a second aspect of the present invention, an air handling device is provided, including the damper structure described in any of the above embodiments.

[0019] The damper structure and air handling device provided in this disclosure can achieve the following technical effects:

[0020] In the closed position, the baffle covers the first gap, thus closing the first gap and preventing air from flowing out of the vent. This closes the damper structure, preventing outdoor mosquitoes, hot summer air, and cold winter air from entering the room when the air handling unit is a fresh air unit. In the open position, the baffle avoids the first gap, allowing the first gap to open and the air to flow out of the vent. This opens the damper structure, enabling the air handling unit to output air normally.

[0021] The baffle can rotate between a closed position and an open position relative to the cover. Compared to the related technology where the blocking part moves along the extension direction of the fresh air outlet, the rotation can reduce the space occupied by the baffle, thereby reducing the volume of the air handling unit.

[0042] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] Combination Figure 1-7 As shown, this embodiment of the present disclosure provides a damper structure 402, including a housing 30, a cover plate 10, and a baffle 20.

[0045] The housing 30 is defined by an air vent 306.

[0046] The cover plate 10 is placed over the air vent 306, and the cover plate 10 has a first notch 103 that is connected to the air vent 306. Air flows into the air vent 306 through the first notch 103, or flows into the first notch 103 through the air vent 306.

[0047] The baffle 20 is rotatably connected to the housing 30 and / or to the cover 10, that is, the baffle 20 is rotatably connected to the housing 30, and / or the baffle 20 is rotatably connected to the cover 10, and the baffle 20 is rotatable relative to the cover 10 between a closed position covering the first notch 103 and an open position opening the first notch 103. Figures 1 to 3 In the middle, the baffle is in the open position.

[0048] The damper structure 402 can be applied to air handling devices used for air conditioning.

[0049] The air handling unit can be an air conditioner. When it is an air conditioner, the air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes a casing, an indoor heat exchanger, and a fan. The casing defines an air duct and is provided with an air inlet 306 and an air outlet 306. Both the air inlet 306 and the air outlet 306 are connected to the air duct. The indoor heat exchanger and the fan are located inside the air duct. Driven by the fan, air enters the air duct through the air inlet 306, exchanges heat with the indoor heat exchanger, and then flows out from the air outlet 306. The damper structure 402 can be located at the air inlet 306 or the air outlet 306. When located at the air inlet 306, the air outlet 306 is the air inlet 306. When located at the air outlet 306, the air outlet 306 is the air outlet 306.

[0050] like Figure 7As shown, the air handling unit can also be a fresh air unit 40. The fresh air unit 40 includes a housing, which defines an air outlet duct and has a first air inlet / outlet 401 and a second air inlet / outlet 306. Both the first air inlet / outlet 401 and the second air inlet / outlet 306 are connected to the air outlet duct. The outer end of the housing is located outdoors, and the inner end of the housing is located indoors. The first air inlet / outlet 401 is located at the outer end of the housing and is connected to the outside, while the second air inlet / outlet 306 is located at the inner end of the housing and is connected to the indoors. Driven by the fan, outdoor air enters the air outlet duct through the first air inlet / outlet 401 and enters the indoors through the second air inlet / outlet 306; alternatively, indoor air enters the air outlet duct through the second air inlet / outlet 306 and enters the outside through the first air inlet / outlet 401, thus achieving the exchange of indoor and outdoor air. The aforementioned damper structure 402 can be located at the first air inlet / outlet 401, in which case the air outlet 306 is the first air inlet / outlet 401. The aforementioned damper structure 402 can also be located at the second air inlet / outlet 306, in which case the air outlet 306 is the second air inlet / outlet 306.

[0051] In the closed position, the baffle 20 covers the first notch 103, thus closing the first notch 103 and preventing air from flowing out of the vent 306 through the first notch 103, thereby closing the damper structure 402. When the air handling unit is a fresh air unit 40, the damper structure 402 closes to block outdoor mosquitoes, hot summer air, and cold winter air from entering the room; Figures 1 to 3 In the open position, the baffle 20 avoids the first notch 103, allowing the first notch 103 to open. The air in the vent 306 flows out through the first notch 103, thus opening the damper structure 402 and enabling the air handling device to output air normally.

[0052] The baffle 20 can rotate relative to the cover 10 between a closed position and an open position. Compared to the related art where the blocking part moves along the extension direction of the fresh air outlet 306, the rotation can reduce the space occupied by the baffle 20, thereby reducing the volume of the air handling unit.

[0053] Optionally, such as Figure 5 As shown, the cover plate 10 includes a plate body 101 and a side wall 102.

[0054] The main body 101 is set to correspond to the air outlet 306.

[0055] The side wall 102 is located on the side of the main plate 101 facing the air outlet 306. One end of the side wall 102 is connected to the main plate 101, and the other end of the side wall 102 abuts against the housing 30.

[0056] The first notch 103 is located on the side wall 102.

[0057] The cover plate 10 includes a main body 101 and a side wall 102. The main body 101 is circular, and its shape and size are adapted to the shape and size of the air vent 306, so that the cover plate 10 covers the air vent 306, serving to shield the air vent 306 and provide protection for it. One end of the side wall 102 is connected to the main body 101, and the connection point is bent. The side wall 102 extends along the main body 101 toward the housing 30, and the other end of the side wall 102 abuts against the housing 30, so that the connection point between the side wall 102 and the main body 101, and the abutment point between the side wall 102 and the housing 30, can be sealed to prevent air leakage.

[0058] The side wall 102 is supported between the main body 101 and the housing 30, creating a gap between them. The first notch 103 is located on the side wall 102. Therefore, the first notch 103 enables the air handling device to vent from the side, improving user comfort. It also prevents direct airflow from the main body 101 and provides aesthetic appeal.

[0059] Optionally, such as Figure 5 As shown, the main body 101 of the plate protrudes from the outer side of the air vent 306.

[0060] The main body 101 protrudes from the outside of the air vent 306, so that the main body 101 is located on the outside of the housing 30. There is a gap between the main body 101 and the housing 30. This gap provides installation space for the side wall 102, making it convenient to set the side wall 102, thereby facilitating the setting of the first notch 103.

[0061] Optionally, such as Figure 5 As shown, there are multiple first notches 103, and the multiple first notches 103 are arranged sequentially along the circumference of the sidewall 102, for example, they are arranged evenly in sequence.

[0062] The side wall 102 extends circumferentially along the main body 101 to form a ring. There are multiple first notches 103, which are arranged sequentially along the circumference of the side wall 102. The first notches 103 are connected to the air vents 306. The arrangement of multiple first notches 103 increases the air outlet area, improves the ventilation efficiency, and allows air to be discharged from multiple directions, improving the comfort of air supply. The sequential arrangement of the first notches 103 along the circumference of the side wall 102 also has a certain aesthetic appeal.

[0063] The shape of the first notch 103 can be any shape, such as a rectangle or a circle.

[0064] Optionally, the baffle 20 is fitted onto the outside of the cover plate 10; or, as... Figures 1 to 3 In the middle, the cover plate 10 is fitted on the outside of the baffle 20.

[0065] When the baffle 20 is fitted onto the outside of the cover plate 10, the shape of the baffle 20 is consistent with the shape of the cover plate 10, and the diameter of the baffle 20 is larger than the diameter of the cover plate 10, so that the baffle 20 can be fitted onto the outside of the cover plate 10. Thus, by rotating the baffle 20, the movement of the baffle 20 relative to the cover plate 10 between the closed position and the open position can be realized.

[0066] When the cover plate 10 is fitted onto the outside of the baffle 20, the shape of the baffle 20 is consistent with the shape of the cover plate 10, and the diameter of the baffle 20 is smaller than the diameter of the cover plate 10, which makes it convenient for the cover plate 10 to be fitted onto the outside of the baffle 20. Thus, the baffle 20 can be rotated to move between the closed position and the open position relative to the cover plate 10.

[0067] Optionally, such as Figure 4 As shown, the baffle 20 is provided with a second notch 201. In the open position, the second notch 201 corresponds to and is connected to the first notch 103. In the closed position, the second notch 201 is offset from the first notch 103.

[0068] The baffle 20 is provided with a second notch 201. The size and shape of the second notch 201 are the same as those of the first notch 103, so that in the open position, the second notch 201 can fully open the first notch 103, and the first notch 103 will not be unable to be fully opened because the size of the second notch 201 is smaller than that of the first notch 103.

[0069] Rotating the baffle 20, when it moves to the open position, the second notch 201 corresponds to and connects with the first notch 103. Air in the vent 306 flows out through the first notch 103 and the second notch 201, or air flows into the vent 306 through the first notch 103 and the second notch 201, thus opening the damper structure 402 and allowing the air handling unit to normally enter and exit. When rotating the baffle 20 to the closed position, the second notch 201 is offset from the first notch 103, and the baffle 20 covers the first notch 103, closing it. This prevents air in the vent 306 from flowing out through the first notch 103, and also prevents air from entering the vent 306 through the first notch 103, thus closing the damper structure 402.

[0070] The number of second gaps 201 is equal to the number of first gaps 103, and they correspond one-to-one. For example, as... Figure 4 and Figure 5 As shown, there are multiple first gaps 103 arranged sequentially along the circumference of the sidewall 102, and there are also multiple second gaps 201 arranged sequentially along the circumference of the sidewall 102.

[0071] Optionally, such as Figure 4As shown, the housing 30 is provided with a guide mating part 302, and the baffle 20 includes a covering part 202 and a guide part 204.

[0072] In the closed position, the cover 202 covers the first notch 103.

[0073] The guide portion 204 is connected to the cover portion 202 and cooperates with the guide mating portion 302 to guide the baffle 20 to move relative to the cover plate 10 between the closed position and the open position.

[0074] The shape and size of the covering part are consistent with the shape and size of the first notch 103, so that in the closed position, the covering part can cover the corresponding first notch 103 to close the first notch 103. There are multiple covering parts, and multiple covering parts and multiple second notches 201 are arranged sequentially and spaced apart along the circumference of the side wall 102, so that when the baffle 20 is rotated to the open position, the second notch 201 corresponds to the first notch 103, the covering part is offset from the first notch 103, and the first notch 103 is opened, thereby realizing that air in the air vent 306 flows out from the first notch 103 or air flows into the air vent 306 through the first notch 103; in the closed position, the covering part 202 corresponds to the first notch 103, and the first notch 103 is closed, thereby realizing that air in the air vent 306 cannot flow out through the first notch 103 or air cannot flow to the air vent 306 through the first notch 103.

[0075] The guide part 204 is connected to the cover part. The housing 30 is provided with a guide mating part 302. The guide part 204 and the guide mating part 302 cooperate to guide the baffle 20 to move between the closed position and the open position relative to the cover plate 10, so as to prevent the baffle 20 from deviating from the preset movement trajectory.

[0076] One of the guide part 204 and the guide mating part 302 is a guide rail, and the other is a guide groove 303. The guide rail is located in the guide groove 303 and can move relative to the guide groove 303 along the length direction of the guide groove 303 to guide the movement trajectory of the baffle 20 relative to the cover plate 10.

[0077] For example, such as Figures 3 to 6 As shown, the guide mating part 302 includes a guide groove 303, which includes a connecting section 3031 and a limiting section 3032. The connecting section 3031 is connected to the housing 30, and the limiting section 3032 is connected to the connecting section 3031, with the connection forming an angle, together defining a guide space with the opening facing the guide rail. The guide part 204 includes a guide rail, which is inserted into the guide space. The guide space extends along the rotation direction of the baffle 20 relative to the cover plate 10. Therefore, when the guide rail moves along the length direction of the guide space, it can guide the baffle 20 to move between the closed position and the open position relative to the cover plate 10, thereby preventing the baffle 20 from deviating from the preset trajectory.

[0078] The number of guide grooves 303 can be one or more, and the number of guide rails can be one or more, such as... Figures 3 to 6 As shown, when there is one guide rail and multiple guide grooves 303, the guide rail can be in the shape of a ring, and the guide rail cooperates with multiple guide grooves 303. When there are multiple guide rails and multiple guide grooves 303, the number of guide rails can be equal to the number of guide grooves 303 and correspond one-to-one.

[0079] The guide portion 204 is provided at one end of the cover portion 202 away from the main body 101 and is located on the outside of the cover portion 202, wherein the direction closer to the axis of the air vent 306 is inward and the direction away from the axis of the air vent 306 is outward.

[0080] Optionally, the housing 30 is provided with a limiting engagement part, and the baffle 20 is provided with a limiting part. The limiting part and the limiting engagement part cooperate to limit the range of motion of the baffle 20 relative to the cover plate 10.

[0081] like Figures 1 to 5 As shown, the baffle 20 is provided with a limiting part, which includes a first limiting part 2031 and a second limiting part 2032. The first limiting part 2031 and the second limiting part 2032 are arranged sequentially along the rotation direction of the baffle 20 relative to the cover plate 10. The housing 30 is provided with a limiting mating part, which includes a first limiting mating part 3011 and a second limiting mating part 3012. The first limiting mating part 3011 and the second limiting mating part 3012 are arranged sequentially along the rotation direction of the baffle 20 relative to the cover plate 10. The first limiting mating part 3011 and the second limiting mating part 3012 are respectively located on both sides of the limiting part. The first limiting part 2031... Corresponding to the first limiting engagement part 3011, the second limiting part 2032 corresponds to the second limiting engagement part 3012. In the open position, the first limiting part 2031 moves to the first limiting engagement part 3011 and abuts against it, thereby restricting the baffle 20 from continuing to move relative to the cover plate 10 beyond the open position in the direction from the closed position to the open position. In the closed position, the second limiting part 2032 moves to the second limiting engagement part 3012 and abuts against it, thereby restricting the baffle 20 from continuing to move relative to the cover plate 10 beyond the closed position in the direction from the open position to the closed position. The limiting parts move between the first limiting engagement part 3011 and the second limiting engagement part 3012, thereby restricting the range of motion of the baffle 20 relative to the cover plate 10, allowing the baffle 20 to move between the open and closed positions, thus making the range of motion of the baffle 20 controllable.

[0082] The first limiting part 2031, the second limiting part 2032, the first limiting mating part 3011, and the second limiting mating part 3012 can all be in the form of protrusions. Through the contact between the protrusions, the first limiting mating part 3011 limits the first limiting part 2031, and the second limiting mating part 3012 limits the second limiting part 2032.

[0083] Optionally, such as Figures 1 to 5 As shown, the damper structure 402 also includes a drive component 305 and a gear 304.

[0084] The gear 304 is driven to connect with the drive member 305. The baffle 20 is provided with gear teeth 205 that mesh with the gear 304. The drive member 305 drives the gear 304 to rotate. The gear 304 meshes with the gear teeth 205 to drive the baffle 20 to rotate relative to the cover plate 10 between the closed position and the open position.

[0085] The damper structure 402 includes a drive component 305, which can be a motor or electric motor. The drive component 305 drives the baffle 20 to rotate, thereby enabling the baffle 20 to move between the open and closed positions relative to the cover plate 10.

[0086] The damper structure 402 also includes a gear 304, which is driven by a drive member 305. The baffle 20 has teeth 205 located on the outside of the guide portion 204 so that the teeth 205 do not affect the engagement between the guide portion 204 and the guide mating portion 302. The direction closer to the axis of the air vent 306 is considered inward, and the direction further away from the axis of the air vent 306 is considered outward. The teeth 205 mesh with the gear 304. Driven by the drive member 305, the gear 304 rotates, meshing with the teeth 205 to rotate the baffle 20. In the open position, the second notch 201 of the baffle 20 corresponds to the first notch 103 of the cover plate 10. In the closed position, the covering portion 202 of the baffle 20 corresponds to the first notch 103 of the cover plate 10, blocking the first notch 103. Therefore, driven by the drive member 305, the baffle 20 can rotate relative to the cover plate 10 between the closed and open positions. The gear teeth 205 extend circumferentially along the guide portion 204, with one of the outermost gear teeth 205 forming a first limiting portion 2031 and the other forming a second limiting portion 2032.

[0087] The rotation of the baffle 20 relative to the cover plate 10 can also be achieved without using the gear 304 drive, such as by chain drive or belt drive.

[0088] According to a second aspect of the present invention, an air handling device is provided, including the damper structure 402 described in any of the above embodiments.
