A fresh air device and a fresh air air conditioner having the same.

Abstract

This invention provides a fresh air device and a fresh air air conditioner having the same. The fresh air device includes a base and a humidification module. The base forms a fresh air duct. The humidification module includes a wet film, which is disposed within the fresh air duct and has multiple wet film holes spaced apart along the extension direction of the wet film. Each wet film hole communicates with the fresh air duct. When the fresh air in the fresh air duct needs humidification, the wet film is in an expanded state, allowing the fresh air to flow through the wet film holes and humidify the flowing fresh air. The large contact area between the fresh air and the wet film ensures sufficient humidification and uniform moisture distribution in the humidified fresh air, resulting in a significant humidification effect and maintaining the humidity of the fresh air. When the fresh air in the fresh air duct does not need humidification, the wet film is in a collecting state, preventing the fresh air from flowing through the wet film holes, reducing the attenuation effect of the wet film on the fresh air flow and minimizing the loss of fresh air flow. The state of the wet film is dynamically adjusted according to the fresh air quality to meet different humidification needs.

The fresh air device of the air conditioner can introduce fresh outdoor air into the room, and the exhaust device of the air conditioner can filter the indoor stale air and discharge it to the outside, thus completing the replacement of fresh air with fresh air. After the outdoor fresh air and the indoor stale air exchange heat through a heat exchanger, the temperature of the fresh air entering the room can be closer to the indoor temperature. In the existing technology, the fresh air is humidified through a wet membrane, but the contact area between the fresh air and the wet membrane is small during the humidification process, and only part of the fresh air flows through the surface of the wet membrane, resulting in insufficient humidification, uneven distribution of moisture in the fresh air after humidification, and an insignificant humidification effect. In addition, the state of the wet membrane cannot be flexibly adjusted according to the quality of the fresh air, resulting in inaccurate humidification treatment of the fresh air. Summary of the Invention

[0026] Outdoor fresh air enters the fresh air duct and flows sequentially through the filter, the first heat exchange duct, and the humidification module. Indoor stale air enters the second heat exchange duct and completes heat exchange with the fresh air flowing through the first heat exchange duct.

[0027] Compared with the prior art, the main advantages of the present invention are as follows:

[0028] (1) The wet membrane is set in the fresh air duct and has wet membrane holes. When the fresh air in the fresh air duct needs to be humidified, the wet membrane is in the unfolded state, and the fresh air can flow through the wet membrane holes. The wet membrane humidifies the fresh air. The contact area between the fresh air and the wet membrane is large, the humidification is sufficient and the moisture in the humidified fresh air is evenly distributed, the humidification effect is obvious, and the humidity of the fresh air is guaranteed. When the fresh air in the fresh air duct does not need to be humidified, the wet membrane is in the collection state, which reduces the attenuation effect of the wet membrane on the fresh air flow and reduces the loss of fresh air flow.

[0029] (2) The wet membrane is laid on the humidifying shell and includes multiple connecting ends. At least a portion of the multiple connecting ends are slidably mounted on the humidifying shell by sliding parts. The two ends of the first connecting rod are respectively connected to two sliding parts, and the two ends of the second connecting rod are respectively connected to two other sliding parts. Rotating the second connecting rod away from the first connecting rod can make the wet membrane in an unfolded state, so that the fresh air in the fresh air duct can flow through the wet membrane holes and the ventilation holes, thereby improving the humidification effect. Rotating the second connecting rod closer to the first connecting rod can make the wet membrane in a collected state, so that the fresh air in the fresh air duct can flow through the ventilation holes, thereby improving the fresh air flow rate. The structure is simple, and the unfolding and collecting process of the wet membrane is simple and timely. The second connecting rod is driven to rotate by the active swing rod and the driven swing rod, and the movement is stable.

[0030] (3) When the humidification module is applied to the fresh air air conditioner, it monitors the quality of fresh air in the fresh air duct in real time, and then dynamically adjusts the state of the wet film to make the wet film expand or collect. The wet film is wetted to different degrees through the spray component, and then the fresh air is humidified to different degrees to meet different humidification needs. The state and wettability of the wet film are adapted to the quality of fresh air, improving the accuracy of air humidification. The fresh air device is linked with the fresh air air conditioner for control, optimizing the control mode of the fresh air air conditioner. Attached Figure Description

Detailed Implementation

[0041] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0043] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0044] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0045] In existing air conditioners, fresh air is humidified through a wet film. However, the contact area between the fresh air and the wet film is small during the humidification process, with only a portion of the fresh air flowing over the surface of the wet film. This results in insufficient humidification, uneven distribution of moisture in the fresh air after humidification, and an insignificant humidification effect. Furthermore, the state of the wet film cannot be flexibly adjusted according to the quality of the fresh air, making it impossible to accurately humidify the fresh air.

[0046] This invention creatively provides a fresh air device, including a base and a humidification module. The base forms a fresh air duct. The humidification module includes a wet film, which is deployable or collectable within the fresh air duct and has multiple wet film holes. The multiple wet film holes are spaced apart along the extension direction of the wet film. Each wet film hole communicates with the fresh air duct. The wet film has an deployed state and a collectable state.

[0047] When the fresh air in the fresh air duct needs to be humidified, the wet membrane is in the unfolded state, and the fresh air in the fresh air duct can flow through the wet membrane holes, and the wet membrane can humidify the flowing fresh air; the contact area between the fresh air and the wet membrane is large, the humidification is sufficient and the moisture in the humidified fresh air is evenly distributed, the humidification effect is obvious, and the humidity of the fresh air is guaranteed.

[0048] When the fresh air in the fresh air duct does not require humidification, the wet membrane is in a collecting state, and the fresh air in the fresh air duct does not flow through the wet membrane holes, reducing the attenuation effect of the wet membrane on the fresh air flow and reducing the loss of fresh air flow.

[0049] Example 1

[0050] <Fresh Air System>

[0051] like Figure 1a , Figure 1b , Figure 3a and Figure 3b As shown, this embodiment provides a fresh air device 2, including a base 22 and a humidification module 1. The base 22 forms a fresh air duct. The humidification module 1 includes a wet film 12, which is deployable or collectible and is disposed within the fresh air duct, forming a plurality of wet film holes 123. The plurality of wet film holes 123 are spaced apart along the extension direction of the wet film 12. Each wet film hole 123 communicates with the fresh air duct. The wet film 12 has an deployed state and a collectible state. Specifically, the humidification module 1 is disposed at the air outlet end of the fresh air duct, and the wet film 12 extends along the width and length directions of the fresh air duct.

[0052] When the fresh air in the fresh air duct needs humidification, the wet membrane 12 is in the unfolded state, and the fresh air in the fresh air duct can flow through the wet membrane holes 123. The wet membrane 12 can humidify the flowing fresh air, and the humidification effect is obvious, ensuring the humidity of the fresh air. When the fresh air in the fresh air duct does not need humidification, the wet membrane 12 is in the collecting state, and the fresh air in the fresh air duct does not flow through the wet membrane holes 123, and the fresh air can flow smoothly.

[0053] To address the complexity of the unfolding and collection process of the wet membrane 12, this embodiment proposes that the humidification module 1 further includes a humidification shell 11, which is disposed within the fresh air duct and has multiple ventilation holes 112. The multiple ventilation holes 112 are arranged sequentially at intervals along the extending direction of the humidification shell 11. The wet membrane 12 is laid on the humidification shell 11 and includes multiple connecting ends, at least a portion of which is slidably disposed on the humidification shell 11.

[0054] Multiple connection ends are far apart, which allows the wet membrane 12 to be in an unfolded state and laid on the humidifying shell 11, thereby connecting the ventilation hole 112 with the wet membrane hole 123, and the fresh air in the fresh air duct can flow through the wet membrane hole 123 and the ventilation hole 112.

[0055] Multiple connection ends are close to each other, which allows the wet membrane 12 to be in a collecting state and located on one side of the humidifying shell 11, thereby connecting the ventilation hole 112 with the fresh air duct, and the fresh air in the fresh air duct can flow through the ventilation hole 112.

[0056] like Figure 2 As shown, in response to the problem of unstable movement of the connecting end during the unfolding or collection of the wet film 12, this embodiment proposes that the humidification module 1 further includes multiple sliding members 13; a sliding member 13 is provided at each connecting end; each sliding member 13 forms a first sliding structure; and the humidification shell 11 forms a second sliding structure.

[0057] The first sliding structure cooperates with the second sliding structure to allow the sliding member 13 to slide relative to the humidifying shell 11, thereby putting the wet film 12 into an unfolded state or a collected state.

[0058] Furthermore, the humidifying shell 11 includes a shell wall 111, which has a columnar structure and a circular arc cross-section; the shell wall 111 has ventilation holes 112 and a second sliding structure is formed at each of the axial ends of the shell wall 111.

[0059] The wet film 12 includes four connecting ends, and correspondingly, the sliding member 13 includes four; the first sliding structure of two sliding members 13 cooperates with a second sliding structure, and the two sliding members 13 are respectively connected to the two connecting ends one by one; the first sliding structure of the other two sliding members 13 cooperates with another second sliding structure, and the two sliding members 13 are respectively connected to the other two connecting ends one by one.

[0060] The four sliding members 13 move away from each other along the corresponding second sliding structure, which allows the wet film 12 to be in an unfolded state; the four sliding members 13 move closer to each other along the corresponding second sliding structure, which allows the wet film 12 to be in a collected state.

[0061] Specifically, the first sliding structure is a slider, which has a cylindrical structure and extends radially along the shell wall 111; the second sliding structure is a groove, which has an arc shape and is coaxial with the shell wall 111; the structure of the slider is adapted to the structure of the groove.

[0062] To address the issue of complex transmission structures required during the unfolding or collection of the wet film 12, this embodiment proposes that the humidification module 1 further includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod extend axially along the shell wall 111 and are spaced apart circumferentially along the shell wall 111. The two ends of the first connecting rod are respectively connected to two sliding members 13 spaced apart axially along the shell wall 111, and the two ends of the second connecting rod are respectively connected to two other sliding members 13 spaced apart axially along the shell wall 111, so that the first connecting rod or the second connecting rod can rotate relative to the shell wall 111 about the axis of the shell wall 111.

[0063] When the second link rotates away from the first link, the wet film 12 can be in an unfolded state; when the second link rotates towards the first link, the wet film 12 can be in a collected state.

[0064] The structure is simple, and the unfolding and collection of the wet film 12 is simple and timely; the second connecting rod is driven to rotate by the active pendulum and the driven pendulum, and the motion is stable.

[0065] Furthermore, the fresh air duct includes a first duct wall and a second duct wall arranged opposite to each other; the humidification module 1 also includes a transmission mechanism, which further includes a drive motor, an active swing arm, and a driven swing arm. The drive motor is mounted on the base 22; the active swing arm and the driven swing arm are arranged opposite to each other along the axial direction of the shell wall 111, and both the active swing arm and the driven swing arm extend radially along the shell wall 111; one end of the active swing arm is connected to one end of the second connecting rod, and the other end of the active swing arm is rotatably mounted on the first duct wall, and the output shaft of the drive motor is drivenly connected to the other end of the active swing arm; one end of the driven swing arm is connected to the other end of the second connecting rod, and the other end of the driven swing arm is rotatably mounted on the second duct wall;

[0066] The drive motor drives the active swing arm to rotate, which in turn drives the driven swing arm to rotate relative to the shell wall 111, thereby enabling the wet film 12 to unfold or be collected.

[0067] Specifically, the four connecting ends include a first connecting end, a second connecting end, a third connecting end, and a fourth connecting end. The first and second connecting ends are located on one axial side of the shell wall 111 and are spaced apart circumferentially along the shell wall 111. The third and fourth connecting ends are located on the other axial side of the shell wall 111 and are spaced apart circumferentially along the shell wall 111. The four sliding members 13 are a first sliding member 131, a second sliding member 132, a third sliding member 133, and a fourth sliding member 134. The first sliding member 131 and the second sliding member 132 are located on one axial side of the shell wall 111 and are spaced apart circumferentially along the shell wall 111. The first sliding member 131 is connected to the first connecting end, and the second sliding member 132 is connected to the second connecting end. The third sliding member 133 is connected to the first connecting end, and the second sliding member 134 is connected to the second connecting end. Sliding member 133 and the fourth sliding member 134 are located on the other side of the axial direction of the shell wall 111, and the third sliding member 133 and the fourth sliding member 134 are spaced apart circumferentially along the shell wall 111; the third sliding member 133 is connected to the third connecting end, and the fourth sliding member 134 is connected to the fourth connecting end; the slide groove includes a first slide groove 113 and a second slide groove 114, the first slide groove 113 is formed on one side of the axial direction of the shell wall 111, and the second slide groove 114 is formed on the other side of the axial direction of the shell wall 111; the slider of the first sliding member 131 and the slider of the second sliding member 132 are embedded in the first slide groove 113, and the slider of the third sliding member 133 and the slider of the fourth sliding member are embedded in the second slide groove 114; all four sliding members 13 can slide, and the first sliding member 131 and the second sliding member 132 can slide relative to each other, and the third sliding member 133 and the fourth sliding member 134 can slide relative to each other; or,

[0068] The first and third connecting ends are fixed ends, while the second and fourth connecting ends are movable ends; the first sliding member 131 and the third sliding member 133 are non-sliding, while the second sliding member 132 and the fourth sliding member 134 are sliding.

[0069] The second slider 132 slides relative to the first slider 131 and the fourth slider 134 slides relative to the third slider 133, which can cause the wet film 12 to unfold or be collected.

[0070] In addition, there are two shell walls 111, which are coaxially arranged and surround a humidification chamber. The humidification chamber has a cylindrical structure. The axial direction of the humidification chamber is perpendicular to the extension direction of the fresh air duct. One shell wall 111 is close to the air inlet end of the fresh air duct, and the other shell wall 111 is close to the air outlet end of the fresh air duct.

[0071] The wet membrane 12 includes two wet membranes, namely a first wet membrane 121 and a second wet membrane 122. The first wet membrane 121 and the second wet membrane 122 are laid on the inner surfaces of the two shell walls 111 respectively. The air inlet of the fresh air duct, the ventilation hole 112 of one shell wall 111, the wet membrane hole 123 of the first wet membrane 121, the humidification chamber, the wet membrane hole 123 of the second wet membrane 122, the ventilation hole 112 of the other shell wall 111 and the air outlet of the fresh air duct are connected in sequence.

[0072] Furthermore, the humidification module 1 also includes a mounting base, which is connected to the humidification shell 11. The mounting base is used to set the humidification shell 11 on the side wall of the fresh air duct.

[0073] <Fresh Air Conditioner>

[0074] like Figure 4a and Figure 4b As shown, a fresh air conditioner includes an indoor unit body and a fresh air device as described above. The fresh air device is disposed on one side of the indoor unit body and further includes a heat exchanger. The fresh air device 2 further includes a heat exchanger 23, a filter 28, a fresh air volute assembly 241, a fresh air fan blade 242, a turbid air volute assembly 251, a turbid air fan blade 252, and a fan motor 26. The base 22 includes a base body, and the base body forms a fresh air duct. The fresh air duct has a filter mounting position 223, a heat exchanger mounting position 222, and a humidifier module mounting position 221 sequentially formed along the fresh air flow direction. The humidifier module mounting position 221 is close to the air outlet end of the fresh air duct. The filter 28 is disposed at the filter mounting position 223, the humidifier module 1 is disposed at the humidifier module mounting position 221, and the heat exchanger 23 is disposed at the heat exchanger mounting position 222. The heat exchanger 23 forms a first heat exchange duct and a second heat exchange duct that are arranged in an alternating manner.

[0075] At the bottom of the base body, a fresh air volute assembly 241 and a stale air volute assembly 251 are arranged side by side. The fresh air volute assembly 241 includes a fresh air volute and a fresh air volute cover, which are fastened together to form a fresh air cavity. The fresh air cavity has a fresh air cavity inlet and a fresh air cavity outlet. The air inlet of the fresh air duct is connected to the outside through a fresh air pipe and to the air inlet of the first heat exchange duct. The fresh air cavity inlet and the air outlet of the first heat exchange duct are connected through a humidification module 1, and the fresh air cavity outlet is connected to the indoor environment. The stale air volute assembly... Component 251 includes a turbid air volute and a turbid air volute cover, which are fastened together to form a turbid air cavity. The turbid air cavity has a turbid air cavity inlet and a turbid air cavity outlet. The air inlet of the second heat exchange air duct is connected to the room, and the air outlet of the second heat exchange air duct is connected to the turbid air cavity inlet. The turbid air cavity outlet is connected to the outside through an exhaust pipe. A fresh air fan blade 242 is installed in the fresh air cavity, and a turbid air fan blade 252 is installed in the turbid air cavity. A fan blade motor 26 is installed between the fresh air volute assembly 241 and the turbid air volute assembly 251.

[0076] Outdoor fresh air enters the fresh air duct through the fresh air duct and flows sequentially through the filter screen 28, the first heat exchange duct and the humidification module 1, and then enters the fresh air chamber and is discharged into the room; when flowing through the wet membrane 12, the fresh air is humidified; indoor stale air enters the second heat exchange duct and completes heat exchange with the fresh air flowing through the first heat exchange duct, and then enters the stale air chamber and is discharged to the outside through the exhaust duct.

[0077] The fresh air device 2 also includes a detection element and a fresh air electrical box 27. The detection element is used to detect the quality of fresh air. The fresh air electrical box 27 is equipped with a fresh air control board. The fresh air control board is electrically connected to the detection element, the fan motor 26, and the drive motor. The detection element detects the quality of fresh air and transmits the detection data to the fresh air control board. The fresh air control board controls the drive motor to operate according to the quality of fresh air, thereby causing the wet membrane 12 to unfold or collect. The fresh air control board controls the fan motor 26 to operate, causing the fresh air fan blade 242 and the stale air fan blade 252 to rotate, thereby introducing outdoor fresh air into the room and exhausting indoor stale air to the outside.

[0078] The fresh air device 2 also includes a mask 21, a base 22, a fresh air volute assembly 241, a fresh air fan blade 242, a turbid air volute assembly 251, a turbid air fan blade 252, and a fan motor 26, all of which are installed inside the mask 21.

[0079] Example 2

[0080] Based on Embodiment 1, the humidification module 1 further includes a spraying component that extends axially along the humidification chamber; a spraying chamber is formed inside the spraying component, and spraying holes are formed on the sidewalls of the spraying component, with the spraying holes connecting the spraying chamber and the humidification chamber.

[0081] Water in the spray chamber can be sprayed onto the wet membrane 12 through the spray holes to wet the wet membrane 12 to varying degrees, thereby allowing the wet membrane 12 to humidify the fresh air to varying degrees.

[0082] The system monitors the quality of fresh air in the fresh air duct in real time, and then dynamically adjusts the state of the wet membrane 12 to make the wet membrane 12 expand or collect. The wet membrane 12 is also wetted to different degrees by the spray device, thereby humidifying the fresh air to different degrees to meet different humidification needs. The state and wettability of the wet membrane 12 are adapted to the quality of fresh air, improving the accuracy of air humidification. The fresh air device 2 is linked with the fresh air air conditioner for control, optimizing the control method of the fresh air air conditioner.

[0083] Example 3

[0084] Unlike Embodiment 1, the humidification module 1 also includes multiple humidification plates, which are rotatably arranged inside the fresh air duct along its width. Each humidification plate is covered with a wet film 12. The tilt angle of the humidification plate is adjusted according to the air quality in the fresh air duct to adjust the flow rate of the fresh air, thereby adjusting the contact time between the fresh air and the wet film 12 to achieve different humidification effects.

[0085] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
