Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a fresh air component and an air conditioner having the same. Background Technology

[0002] In existing technologies, to enhance the functionality of air conditioners, a fresh air component is typically installed within the unit. However, current fresh air components are relatively simple in function, generally only providing fresh air. Adding functions such as exhaust, indoor circulation, and heat exchange would inevitably increase the number of components, resulting in a more complex structure, larger footprint, and lower assembly efficiency. In other words, existing fresh air components cannot simultaneously offer the advantages of multiple functions, simple structure, small size, high assembly efficiency, and low cost. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a fresh air component that combines the advantages of multiple functions, simple structure, small size, high assembly efficiency, and low cost.

[0004] The present invention also aims to provide an air conditioner having the above-mentioned fresh air component.

[0005] A fresh air component according to an embodiment of the present invention includes: a housing assembly having a fresh air inlet, an indoor air inlet, and an air outlet, the housing assembly having an exhaust duct and a ventilation duct inside, the outlet of the exhaust duct being normally connected to the fresh air inlet; a fan wheel disposed within the ventilation duct and used to allow air to enter through the ventilation duct via the fresh air inlet or the indoor air inlet, and to exit through the exhaust duct or the air outlet; and a first switching valve movable between a first position and a second position, wherein in the first position, the first switching valve... The first switching valve connects the ventilation duct to the fresh air inlet and blocks the indoor air inlet. In the second position, the first switching valve blocks the ventilation duct from the fresh air inlet and connects it to the indoor air inlet. The second switching valve is movable between a third position and a fourth position. In the third position, the second switching valve connects the ventilation duct to the air outlet and blocks the exhaust duct. In the fourth position, the second switching valve blocks the ventilation duct from the air outlet and connects it to the exhaust duct.

[0006] According to an embodiment of the present invention, the fresh air component is provided with a fresh air inlet, an indoor air inlet, and an air outlet on the housing assembly, and an exhaust duct and a ventilation duct are provided inside the housing assembly. When the first switching valve is in the first position, connecting the ventilation duct to the fresh air inlet and blocking the indoor air inlet, and the second switching valve is in the third position, connecting the ventilation duct to the air outlet and blocking the exhaust duct, the impeller operates to introduce outdoor air into the ventilation duct through the fresh air inlet and exhaust the introduced air from the air outlet into the room, thereby achieving the purpose of introducing outdoor air into the room, thus enabling the fresh air component of this application to have a fresh air function. When the first switching valve is in the second position, blocking the ventilation duct from the fresh air inlet and connecting it to the indoor air inlet, and the second switching valve is in the fourth position, blocking the ventilation duct from the air outlet and connecting it to the exhaust duct, the impeller operates to introduce indoor air into the ventilation duct through the indoor air inlet and exhaust the introduced air sequentially from the exhaust duct and the fresh air inlet. The air vents out to the outside, thus exhausting indoor air to the outside, thereby giving the fresh air component of this application an exhaust function. When the first switching valve is in the second position, blocking the ventilation duct from the fresh air inlet and connecting it to the indoor air inlet, and when the second switching valve is in the third position, connecting the ventilation duct to the air outlet and blocking it from the exhaust duct, the impeller can draw indoor air into the ventilation duct through the indoor air inlet and exhaust the drawn air out of the air outlet, so that the indoor air can be effectively circulated, thereby giving the fresh air component of this application a circulation function. In other words, the fresh air component of this application has multiple functions (fresh air function, exhaust function, and circulation function), and the switching between multiple functions can be achieved through only two switching valves, without increasing the number of components in the fresh air component. Thus, the fresh air component of this application can take into account the advantages of multiple functions, simple structure, small size, high assembly efficiency, and low cost.

[0007] According to some embodiments of the present invention, in a fresh air component, the first switching valve is rotatably or translationally disposed on the housing assembly.

[0008] According to some embodiments of the present invention, the first switching valve reciprocates between the first position and the second position.

[0009] According to some embodiments of the present invention, in the fresh air component, the second switching valve is rotatably or translationally disposed on the housing assembly.

[0010] According to some embodiments of the present invention, in the fresh air component, the second switching valve reciprocates between the third position and the fourth position.

[0011] According to some embodiments of the present invention, the fresh air inlet is connected to the ventilation duct through a first air duct, the indoor air inlet is connected to the ventilation duct through a second air duct, the first switching valve is disposed at the outlet of the first air duct and the outlet of the second air duct, and the fresh air component further includes a temperature regulating component disposed in the first air duct and the second air duct.

[0012] Optionally, the temperature regulating element is located in the refrigerant circulation system.

[0013] According to some embodiments of the present invention, the fresh air component has a first air duct inside the housing assembly. The first air duct is tubular and open at both ends in the axial direction to communicate with the fresh air inlet and the ventilation duct, respectively. The side wall of the first air duct has a connecting opening to communicate with the exhaust duct.

[0014] According to some embodiments of the present invention, the fresh air component further includes an air handling unit disposed within the ventilation duct and used for at least one of temperature regulation, humidity regulation, purification regulation, and odor regulation.

[0015] An air conditioner according to an embodiment of the present invention includes: a heat exchange component, the heat exchange component including a heat exchange device and an air supply device for causing airflow to flow through the heat exchange device; and a fresh air component, the fresh air component being the aforementioned fresh air component, wherein the fresh air component and the heat exchange component each supply air separately or in combination.

[0016] According to the embodiments of the present invention, by adopting the aforementioned fresh air component, the air conditioner of the present application can have multiple functions without increasing the number of air conditioner parts excessively, thereby enabling the air conditioner to take into account the advantages of multiple functions, high assembly efficiency, and low cost.

[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] The fresh air component 100 of the present invention is described below with reference to the accompanying drawings.

[0042] like Figures 4-7 As shown, the fresh air component 100 according to an embodiment of the present invention includes a housing assembly 10, a fan wheel 20, a first switching valve 30, and a second switching valve 40.

[0043] Among them, such as Figure 5 As shown, the housing assembly 10 has a fresh air inlet 11, an indoor air inlet 12, and an air outlet 13. The housing assembly 10 also contains an exhaust duct 14 and a ventilation duct 15. The outlet of the exhaust duct 14 is always connected to the fresh air inlet 11. This "always connected" means that the outlet of the exhaust duct 14 and the fresh air inlet 11 are always in a connected state. Therefore, when the exhaust duct 14 and the fresh air inlet 11 are connected, there is no need to install a control device between them to prevent them from being connected, thus reducing the number of components, avoiding increasing the internal structure of the housing assembly 10, and ensuring the simplicity of the fresh air component 100's structure.

[0044] like Figure 4 As shown, the impeller 20 is disposed within the ventilation duct 15. The impeller 20 is used to allow air to enter the ventilation duct 15 through the fresh air inlet 11 or the indoor air inlet 12, and to allow air to exit through the exhaust duct 14 or the air outlet 13. In other words, the impeller 20 can drive the flow of air inside and outside the ventilation duct 15, ensuring that air outside the ventilation duct 15 can enter the ventilation duct 15 through the fresh air inlet 11 or the indoor air inlet 12, and ensuring that air entering the ventilation duct 15 can be discharged through the exhaust duct 14 or the air outlet 13.

[0045] Since the outlet of the exhaust duct 14 is connected to the fresh air inlet 11, when the impeller 20 drives the air in the ventilation duct 15 to flow into the exhaust duct 14, the air in the exhaust duct 14 can be discharged through the fresh air inlet 11.

[0046] In other words, the new air inlet 11 of this application not only has the function of introducing air, but also the function of expelling air. With this configuration, there is no need to set an air outlet on the housing assembly 10, so as to simplify the structure of the housing assembly 10 and improve the production efficiency of the housing assembly 10.

[0047] It should be noted that by placing the impeller 20 inside the ventilation duct 15, that is, placing the impeller 20 inside the housing assembly 10, this application ensures that the impeller 20 can drive the air circulation inside and outside the housing assembly 10 when it is working, while also protecting the impeller 20 with the housing assembly 10, thereby extending the service life of the impeller 20.

[0048] The first switching valve 30 is movable between a first position and a second position, such as Figure 5 As shown, when the first switching valve 30 is in the first position, the first switching valve 30 connects the ventilation duct 15 with the fresh air inlet 11 and blocks it from the indoor air inlet 12. At this time, the fan wheel 20 can introduce outdoor air into the ventilation duct 15 through the fresh air inlet 11.

[0049] like Figure 6 and Figure 7 As shown, when the first switching valve 30 is in the second position, the first switching valve 30 blocks the ventilation duct 15 from the fresh air inlet 11 and connects it to the indoor air inlet 12. At this time, the impeller 20 can introduce indoor air into the ventilation duct 15 through the indoor air inlet 12.

[0050] Therefore, by setting a first switching valve 30, this application can both block the ventilation duct 15 from the indoor air inlet 12 when the ventilation duct 15 is connected to the fresh air inlet 11, and connect the ventilation duct 15 to the indoor air inlet 12 when the ventilation duct 15 is blocked from the fresh air inlet 11. Thus, the fresh air component 100 of this application has both the function of introducing indoor air and the function of introducing outdoor air. Moreover, the two functions (the function of introducing indoor air and the function of introducing outdoor air) can be switched through a single structural component (the first switching valve 30). Thus, the fresh air component 100 of this application can take into account the advantages of multiple functions, simple structure, few parts, small size, high assembly efficiency, and low cost.

[0051] like Figure 5 and Figure 7 As shown, the second switching valve 40 is movable between the third and fourth positions. In the third position, the second switching valve 40 connects the ventilation duct 15 with the air outlet 13 and blocks the exhaust duct 14. At this time, the impeller 20 can exhaust the air in the ventilation duct 15 into the room through the air outlet 13.

[0052] like Figure 6As shown, when the second switching valve 40 is in the fourth position, the second switching valve 40 blocks the ventilation duct 15 from the air outlet 13 and connects it to the exhaust duct 14. At this time, the impeller 20 can exhaust the air in the ventilation duct 15 to the outside through the exhaust duct 14 and the fresh air inlet 11 connected to the outlet of the exhaust duct 14.

[0053] Therefore, by setting a second switching valve 40, this application can both block the ventilation duct 15 from the exhaust duct 14 when the ventilation duct 15 is connected to the air outlet 13, and connect the ventilation duct 15 to the exhaust duct 14 when the ventilation duct 15 is blocked from the air outlet 13. Thus, the fresh air component 100 of this application has both the function of exhausting air into the room and the function of exhausting air into the outside. Moreover, the two functions (exhausting air into the room and exhausting air into the outside) can be switched through a single structural component (second switching valve 40). This further enables the fresh air component 100 of this application to take into account the advantages of multiple functions, simple structure, few parts, small size, high assembly efficiency, and low cost.

[0054] As can be seen from the above structure, the fresh air component 100 of this embodiment of the invention, by providing a fresh air inlet 11, an indoor air inlet 12, and an air outlet 13 on the housing assembly 10, and by providing an exhaust duct 14, a ventilation duct 15, a movable first switching valve 30, and a movable second switching valve 40 inside the housing assembly 10, when the first switching valve 30 moves to the first position so that the ventilation duct 15 is connected to the fresh air inlet 11 and blocked from the indoor air inlet 12, and when the second switching valve 40 moves to the third position so that the ventilation duct 15 is connected to the air outlet 13 and blocked from the exhaust duct 14, the impeller 20 can work to introduce outdoor air into the ventilation duct 15 through the fresh air inlet 11 and exhaust the introduced air to the room from the air outlet 13 (the specific air flow path in this example can be found in [reference needed]). Figure 5 (The path shown by the middle arrow) is used to introduce outdoor air into the room, thereby enabling the fresh air component 100 of this application to have a fresh air function.

[0055] The fresh air function mainly introduces fresh outdoor air and exhausts it into the room, thereby changing the indoor air quality and improving the user experience.

[0056] When the first switching valve 30 is in the second position, blocking the ventilation duct 15 from the fresh air inlet 11 and connecting it to the indoor air inlet 12, and when the second switching valve 40 is in the fourth position, blocking the ventilation duct 15 from the air outlet 13 and connecting it to the exhaust duct 14, the impeller 20 operates to introduce indoor air into the ventilation duct 15 through the indoor air inlet 12 and to discharge the introduced air sequentially from the exhaust duct 14 and the fresh air inlet 11 to the outside (the specific air flow path in this example can be found in [reference needed]). Figure 6(The path shown by the middle arrow) is used to exhaust indoor air to the outside, thereby enabling the fresh air component 100 of this application to have an exhaust function.

[0057] The exhaust function primarily removes stale air from the room, improving indoor air quality and further enhancing the user experience.

[0058] When the first switching valve 30 is in the second position, blocking the ventilation duct 15 from the fresh air inlet 11 and connecting it to the indoor air inlet 12, and when the second switching valve 40 is in the third position, connecting the ventilation duct 15 to the air outlet 13 and blocking it from the exhaust duct 14, the impeller 20 operates to introduce indoor air into the ventilation duct 15 through the indoor air inlet 12 and exhaust the introduced air out of the air outlet 13 into the room (the specific air flow path in this example can be found in [reference needed]). Figure 7 (The path shown by the middle arrow) allows for effective air circulation in the room, thus enabling the fresh air component 1000 of this application to have a circulation function.

[0059] The circulation function mainly circulates the air in the room to ensure air circulation and improve the user experience.

[0060] In summary, the fresh air component 100 of this application has multiple functions (fresh air function, exhaust function and circulation function), and the switching between multiple functions can be achieved by only two switching valves (first switching valve 30 and second switching valve 40), without increasing the number of parts of the fresh air component 100. Thus, the fresh air component 100 of this application can take into account the advantages of multiple functions, simple structure, small size, high assembly efficiency and low cost.

[0061] It is understandable that, compared with existing fresh air components that have fewer functions but simpler structures or more functions but more complex structures, the fresh air component 100 of this application has more functions and a simpler structure. This not only improves the user experience but also reduces the size of the fresh air component 100, making it easier to install or deploy. Furthermore, it can improve the production efficiency of the fresh air component 100 and reduce its production cost.

[0062] In the description of this invention, features defined with "first", "second", "third" and "fourth" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or importance.

[0063] It should be noted that when the first switching valve 30 of this application blocks the ventilation duct 15 from the fresh air inlet 11 and connects it to the indoor air inlet 12 in the second position, and when the second switching valve 40 connects the ventilation duct 15 to the air outlet 13 and blocks it from the exhaust duct 14 in the third position, foreign objects and dust in the outdoor air can also be prevented from entering the fresh air component 100.

[0064] In other words, the fresh air component 100 of this application also has the function of isolating the entry of external foreign objects, so as to further increase the function of the fresh air component 100. With this function, the ventilation duct 15 and the fresh air inlet 11 can be blocked by the first switching valve 30 and the ventilation duct 15 and the exhaust duct 14 can be blocked by the second switching valve 40 before the fresh air component 100 is turned off, so as to prevent foreign objects, dust and other objects in the outdoor air from entering the fresh air component 100, ensuring the cleanliness of the fresh air component 100, thereby ensuring that the fresh air component 100 can effectively introduce fresh air, realize the internal circulation of indoor air or realize the exhaust of indoor air when it is used again.

[0065] In some examples, a connecting pipe is provided at the fresh air inlet 11, with the end of the connecting pipe away from the fresh air inlet 11 located outdoors, ensuring that when the first switching valve 30 moves to the first position to connect the ventilation duct 15 with the fresh air inlet 11, the impeller 20 can effectively introduce outdoor air into the ventilation duct 15 through the fresh air inlet 11.

[0066] Optionally, the fresh air component 100 also includes a fan 70, which is located in the ventilation duct 15 and connected to the impeller 20. The fan 70 is used to drive the impeller 20 to rotate, so as to ensure that the impeller 20 can work normally, thereby enabling the ventilation duct 15 to take in air through the fresh air inlet 11 or the indoor air inlet 12, and to ensure that the ventilation duct 15 can exhaust air through the exhaust duct 14 or the air outlet 13.

[0067] In some examples, the housing assembly 10 includes an air inlet volute and an air outlet volute, which are mated to form the housing assembly 10. A fresh air inlet 11 and an indoor air inlet 12 are formed on the air inlet volute, and an air outlet 13 is formed on the air outlet volute. The structure and connection method of the air inlet volute and the air outlet volute are prior art well known to those skilled in the art and will not be described in detail here.

[0068] In some embodiments of the present invention, the first switching valve 30 is rotatably disposed on the housing assembly 10. That is, the position of the first switching valve 30 relative to the housing assembly 10 can change, so that the first switching valve 30 has a first position and a second position, thereby enabling the first switching valve 30 to connect the ventilation duct 15 with the fresh air inlet 11 or to connect the ventilation duct 15 with the indoor air inlet 12.

[0069] It should be noted that by rotatably mounting the first switching valve 30 on the housing assembly 10, the position of the first switching valve 30 can be switched, the first switching valve 30 can be easily driven, and the movement of the first switching valve 30 occupies little space, thereby reducing the volume of the fresh air component 100.

[0070] Optionally, the first switching valve 30 includes a first limiting post and a first rotating plate. The first limiting post is fixedly connected to the housing assembly 10, and the first rotating plate is rotatably connected to the first limiting post, so that the first rotating plate can rotate relative to the housing assembly 10, that is, the first switching valve 30 is rotatably disposed on the housing assembly 10.

[0071] In some examples, the fresh air inlet 11 and the indoor air inlet 12 are both located on the rear side wall of the housing assembly 10 and are spaced apart. The first limiting post is located on the housing assembly 10 between the fresh air inlet 11 and the indoor air inlet 12. The first rotating plate is rotatably connected to the first limiting post. When the first rotating plate rotates toward the direction closer to the fresh air inlet 11, the first rotating plate can block the fresh air inlet 11, thereby blocking the ventilation duct 15 from the fresh air inlet 11 and connecting it with the indoor air inlet 12, which means that the first switching valve 30 is switched to the second position. When the first rotating plate rotates toward the direction closer to the indoor air inlet 12, the first rotating plate can block the indoor air inlet 12, thereby connecting the ventilation duct 15 with the fresh air inlet 11 and blocking it from the indoor air inlet 12, which means that the first switching valve 30 is switched to the first position.

[0072] Optionally, the housing assembly 10 includes a first driving member (not shown in the figure), which drives the first rotating plate to rotate relative to the first limiting post, thereby allowing the first switching valve 30 to move between a first position and a second position. The first driving member may be a drive motor or a drive cylinder, etc.

[0073] In other examples, the first switching valve 30 is translatably disposed on the housing assembly 10. That is, the first switching valve 30 is not limited to being rotatably connected to the housing assembly 10, but can also be movably connected to the housing assembly 10, so that the position of the first switching valve 30 relative to the housing assembly 10 can change, that is, the first switching valve 30 can have a first position and a second position. In this way, the first switching valve 30 can also be used to connect the ventilation duct 15 with the fresh air inlet 11 or to connect the ventilation duct 15 with the indoor air inlet 12.

[0074] Furthermore, the fact that the first switching valve 30 can be slidably mounted on the housing assembly 10 also gives the first switching valve 30 advantages such as easy driving and small space occupation for movement.

[0075] Optionally, the first switching valve 30 includes a first guide rail and a first movable plate. The first guide rail is fixedly connected to the housing assembly 10, and the first movable plate is movably disposed on the first guide rail, so that the first movable plate can move relative to the housing assembly 10, that is, the first switching valve 30 is movably disposed on the housing assembly 10.

[0076] In some examples, both the fresh air inlet 11 and the indoor air inlet 12 are disposed on the rear sidewall of the housing assembly 10 and are spaced apart. Two first guide rails are provided, spaced apart on opposite sides of the fresh air inlet 11 and the indoor air inlet 12. For example, when the fresh air inlet 11 and the indoor air inlet 12 are vertically spaced on the rear sidewall of the housing assembly 10, the two first guide rails are spaced apart on opposite left and right sides of the fresh air inlet 11 and the indoor air inlet 12; when the fresh air inlet 11 and the indoor air inlet 12 are horizontally spaced on the rear sidewall of the housing assembly 10, the two first guide rails are spaced apart on opposite left and right sides of the fresh air inlet 11 and the indoor air inlet 12. On opposite sides, the first movable plate is movably mounted on the first guide rail. When the first movable plate moves toward the direction of the fresh air inlet 11, it can block the fresh air inlet 11, thereby blocking the ventilation duct 15 from the fresh air inlet 11 and connecting it with the indoor air inlet 12, which means that the first switching valve 30 is switched to the second position. When the first movable plate moves toward the direction of the indoor air inlet 12, it can block the indoor air inlet 12, thereby connecting the ventilation duct 15 with the fresh air inlet 11 and blocking it from the indoor air inlet 12, which means that the first switching valve 30 is switched to the first position.

[0077] Optionally, the housing assembly 10 includes a second driving member (not shown in the figure), which drives the first moving plate to move relative to the first guide rail, thereby allowing the first switching valve 30 to move between a first position and a second position. The second driving member can also be a drive motor or a drive cylinder, etc.

[0078] In some embodiments of the present invention, the first switching valve 30 reciprocates between a first position and a second position. That is, when the first switching valve 30 is in the first position, it can be driven to switch directly to the second position; correspondingly, when the first switching valve 30 is in the second position, it can also be driven to switch directly to the first position. Furthermore, the first switching valve 30 can switch arbitrarily multiple times between the first and second positions, thereby enabling the fresh air component 100 of this application to repeatedly introduce indoor or outdoor air, thus ensuring that the fresh air component 100 has the function of introducing both indoor and outdoor air.

[0079] In addition, the reciprocating motion also makes the space required for the first switching valve 30 to move smaller, thereby making the structure of the fresh air component 100 compact and further reducing the volume of the fresh air component 100.

[0080] In some specific examples, when the first switching valve 30 is rotatably disposed on the housing assembly 10 and driven to rotate by the first driving member, the first driving member may be a rotary motor. When the output shaft of the rotary motor rotates clockwise, the first switching valve 30 can switch from a first position to a second position; when the output shaft of the rotary motor rotates counterclockwise, the first switching valve 30 can switch from a second position to a first position, thereby enabling the first switching valve 30 to reciprocate between the first position and the second position.

[0081] In some embodiments of the present invention, the second switching valve 40 is rotatably disposed on the housing assembly 10. That is, the position of the second switching valve 40 relative to the housing assembly 10 can also change, so that the second switching valve 40 has a third position and a fourth position, thereby enabling the second switching valve 40 to connect the ventilation duct 15 with the air outlet 13 or to connect the ventilation duct 15 with the exhaust duct 14.

[0082] Optionally, the second switching valve 40 includes a second limiting post and a second rotating plate. The second limiting post is fixedly connected to the housing assembly 10 and located between the air outlet 13 and the exhaust duct 14. The second rotating plate is rotatably connected to the second limiting post, allowing the second rotating plate to rotate relative to the housing assembly 10, thus enabling the second switching valve 40 to be rotatably mounted on the housing assembly 10. When the second rotating plate rotates towards the air outlet 13, it blocks the air outlet 13, thereby blocking the ventilation duct 15 from the air outlet 13 and connecting it to the exhaust duct 14, thus switching the second switching valve 40 to the fourth position. When the second rotating plate rotates towards the exhaust duct 14, it blocks the exhaust duct 14, thereby connecting the ventilation duct 15 to the air outlet 13 and blocking it from the exhaust duct 14, thus switching the second switching valve 40 to the third position.

[0083] Optionally, the housing assembly 10 includes a third driving member (not shown in the figure), which drives the second rotating plate to rotate relative to the second limiting post, thereby allowing the second switching valve 40 to move between a third position and a fourth position. The third driving member can be a drive motor or a drive cylinder, etc.

[0084] In other examples, the second switching valve 40 is translatably disposed on the housing assembly 10. That is, the second switching valve 40 is not limited to being rotatably connected to the housing assembly 10, but can also be movably connected to the housing assembly 10, so that the position of the second switching valve 40 relative to the housing assembly 10 can change, that is, the second switching valve 40 can have a third position and a fourth position. In this way, the second switching valve 40 can also be used to connect the ventilation duct 15 with the air outlet 13 or to connect the ventilation duct 15 with the exhaust duct 14.

[0085] The second switching valve 40 is rotatably or translationally mounted on the housing assembly 10, which makes the second switching valve 40 easy to drive and also makes the movement of the second switching valve 40 occupy less space, thereby reducing the volume of the fresh air component 100.

[0086] Optionally, the second switching valve 40 includes a second guide rail and a second movable plate. The inlets of the air outlet 13 and the exhaust duct 14 are both located on the top wall of the housing assembly 10 and are spaced apart. The second guide rail includes two rails, which are spaced apart on opposite sides of the inlets of the air outlet 13 and the exhaust duct 14 and are fixedly connected to the housing assembly 10. The second movable plate is movably mounted on the second guide rail, so that the second movable plate can move relative to the housing assembly 10.

[0087] When the second movable plate moves toward the direction of the air outlet 13, it can block the air outlet 13, thereby blocking the ventilation duct 15 from the air outlet 13 and connecting it with the exhaust duct 14, which means that the second switching valve 40 is switched to the fourth position; when the second movable plate moves toward the direction of the exhaust duct 14, it can block the exhaust duct 14, thereby connecting the ventilation duct 15 with the air outlet 13 and blocking it from the exhaust duct 14, which means that the second switching valve 40 is switched to the third position.

[0088] Optionally, the housing assembly 10 includes a fourth driving member (not shown in the figure), which drives the second movable plate to move relative to the second guide rail, thereby allowing the second switching valve 40 to move between a third position and a fourth position. The fourth driving member can also be a drive motor or a drive cylinder, etc.

[0089] In some embodiments of the present invention, the second switching valve 40 reciprocates between a third position and a fourth position. That is, when the second switching valve 40 is in the third position, it can be driven to switch directly to the fourth position; correspondingly, when the second switching valve 40 is in the fourth position, it can also be driven to switch directly to the third position. Furthermore, the second switching valve 40 can switch between the third and fourth positions multiple times at will, thereby enabling the fresh air component 100 of this application to repeatedly exhaust air into the room or into the outside, thus ensuring that the fresh air component 100 has the function of exhausting air into the room and into the outside.

[0090] In addition, the reciprocating motion of the second switching valve 40 can make the space required for the second switching valve 40 during movement small, thereby making the structure of the fresh air component 100 compact and further reducing the volume of the fresh air component 100.

[0091] In some embodiments of the present invention, such as Figure 5 As shown, the fresh air inlet 11 is connected to the ventilation duct 15 via the first air duct 16, and the indoor air inlet 12 is connected to the ventilation duct 15 via the second air duct 17. A first switching valve 30 is located at the outlet of the first air duct 16 and the outlet of the second air duct 17. This facilitates the use of the first switching valve 30 to block the outlet of either the first air duct 16 or the outlet of the second air duct 17. Specifically, when the first switching valve 30 blocks the outlet of the first air duct 16 (e.g....), Figure 6 and Figure 7 As shown), the ventilation duct 15 and the fresh air inlet 11 can be blocked. At this time, the impeller 20 can introduce indoor air from the indoor air inlet 12 through the second duct 17. When the first switching valve 30 blocks the outlet of the second duct 17 (as shown), Figure 5 As shown, the ventilation duct 15 can be blocked from the indoor air inlet 12. At this time, the impeller 20 can introduce outdoor air from the fresh air inlet 11 through the first air duct 16.

[0092] It should be noted that by setting the first switching valve 30 at the outlet of the first air duct 16 and the outlet of the second air duct 17, the first switching valve 30 can be close to the outlet of the first air duct 16 and the outlet of the second air duct 17 at the same time. This makes it easier to control the air outlet of the first air duct 16 or the air outlet of the second air duct 17 using a single first switching valve 30, thereby reducing the difficulty of control and also reducing the number of parts used.

[0093] Optionally, such as Figure 5 and Figure 6As shown, the fresh air component 100 also includes a temperature regulating component 50, which is disposed within the first air duct 16 and the second air duct 17. The temperature regulating component 50 is used to regulate the temperature of the air entering the first air duct 16 and the second air duct 17, so that the temperature of the air entering the first air duct 16 and the second air duct 17 can be close to the preset indoor temperature. In this way, when the air is exhausted through the air outlet 13, the comfort of the fresh air component 100 can be improved, thereby enhancing the user experience.

[0094] In some examples, the temperature control element 50 can be linked to the working state of the second switching valve 40. Specifically, when the second switching valve 40 is in the third position, that is, when the ventilation duct 15 is connected to the air outlet 13, the temperature control element 50 starts to work to adjust the temperature of the air entering the first air duct 16 and the second air duct 17, thereby ensuring that the temperature of the air discharged from the air outlet 13 to the room is close to the preset temperature of the room, thus improving the user experience.

[0095] Optionally, when the second switching valve 40 is in the fourth position, the temperature regulating element 50 is switched to the closed state. That is, when the ventilation duct 15 is connected to the exhaust duct 14, the temperature regulating element 50 is closed. At this time, the air entering the fresh air component 100 will be directly exhausted to the outside and will not affect the indoor users. At this time, the temperature regulating element 50 is not controlled to regulate the temperature of the air entering the first duct 16 and the second duct 17, which can reduce the number of times the temperature regulating element 50 is used and reduce the frequency of use of the temperature regulating element 50, thereby extending the service life of the temperature regulating element 50.

[0096] Of course, in some other examples, when the fresh air component 100 is in operation, the temperature control component 50 can also be in operation continuously. That is, when the fresh air component 100 is in operation, the temperature control component 50 can always adjust the temperature of the air entering the first air duct 16 and the second air duct 17, so as to avoid frequently switching the temperature control component 50 on and off and reduce the control difficulty of the temperature control component 50.

[0097] Optionally, the temperature regulating element 50 is disposed in the refrigerant circulation system. The refrigerant circulation system is used to change the temperature of the temperature regulating element 50 itself, thereby ensuring that the temperature regulating element 50 can effectively regulate the temperature of the air entering the first air duct 16 and the second air duct 17.

[0098] Optionally, the temperature regulating element 50 is formed as a capillary tube filled with refrigerant. The refrigerant circulation system includes a compressor, a condenser, an evaporator, and the temperature regulating element 50 formed as a capillary tube. The compressor, condenser, capillary tube, and evaporator are connected in series to form the refrigerant circulation system. This allows the temperature regulating element 50 to regulate the temperature of the air entering the first air duct 16 and the second air duct 17. The temperature regulation here includes both heating and cooling, so that the temperature of the air discharged from the air outlet 13 is close to the preset indoor temperature.

[0099] It should be noted that when the fresh air component 100 is applied to the air conditioner 1000, the temperature regulating element 50, which is formed as a capillary tube, can be connected to the refrigerant circulation system of the air conditioner 1000 itself. This arrangement allows the air temperature after heat exchange through the temperature regulating element 50 to be close to the air temperature after heat exchange through the refrigerant circulation system, thereby allowing the air temperature discharged from the air outlet 13 to the room to be close to the preset indoor temperature, thus improving the comfort of the fresh air component 100.

[0100] It should also be noted that by placing the temperature regulating element 50 in the refrigerant circulation system of the air conditioner 1000 itself, it is ensured that only one temperature regulating element 50 is needed to regulate the temperature of the air entering the first air duct 16 and the second air duct 17. There is no need to repeatedly set up the compressor, evaporator and other structures, which further simplifies the components of the fresh air component 100 and reduces the production cost of the fresh air component 100.

[0101] In some embodiments of the present invention, such as Figure 6 As shown, the housing assembly 10 has a first air duct 16, which is tubular and open at both ends along the axial direction, so that the first air duct 16 can be connected to the fresh air inlet 11 and the ventilation duct 15 respectively. In this way, when the impeller 20 is working, the air located at the fresh air inlet 11 can enter the ventilation duct 15 through the first air duct 16.

[0102] Optionally, such as Figure 6 As shown, the first air duct 16 has a connecting port 161 on its side wall, which connects to the exhaust air duct 14. This connects the exhaust air duct 14 to the first air duct 16, and also connects the exhaust air duct 14 to the fresh air inlet 11. When the first switching valve 30 is in the second position, blocking the ventilation duct 15 from the fresh air inlet 11 and connecting it to the indoor air inlet 12, and when the second switching valve 40 is in the fourth position, blocking the ventilation duct 15 from the air outlet 13 and connecting it to the exhaust air duct 14, the air entering the ventilation duct 15 through the indoor air inlet 12 can be discharged to the outside through the exhaust air duct 14, the connecting port 161, the first air duct 16, and the fresh air inlet 11, thereby removing the stale air from the room.

[0103] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the fresh air component 100 also includes an air handling unit 60, which is disposed within the ventilation duct 15 for temperature regulation. This allows for further regulation of the temperature of the air entering the ventilation duct 15, ensuring that the temperature of the air discharged through the air outlet 13 is close to the preset indoor temperature.

[0104] In a specific example, the air handling unit 60 is formed as a heating element and / or a cooling element, which is disposed within the ventilation duct 15 to achieve temperature regulation.

[0105] In some examples, the air handling unit 60 is located within the ventilation duct 15 for humidity regulation. This regulates the humidity of the air entering the ventilation duct 15, ensuring that the air exhausted through the air outlet 13 has a certain humidity level, thereby altering the indoor air humidity, ensuring air comfort, and improving the user experience.

[0106] In a specific example, the air handling unit 60 is formed as a humidifying film, which is disposed within the ventilation duct 15 to achieve humidity regulation.

[0107] In other examples, the air handling unit 60 is disposed within the ventilation duct 15 for odor regulation. This regulates the odor of the air entering the ventilation duct 15, for example, by increasing the fragrance of the air and ensuring that the air exhausted through the air outlet 13 has a certain fragrance, thereby altering the odor of the indoor air, ensuring that the indoor air has a certain fragrance, and improving the user experience.

[0108] In a specific example, the air handling unit 60 is formed as an aromatherapy module, which is located within the ventilation duct 15 to achieve odor regulation.

[0109] In other examples, the air handling unit 60 is disposed within the ventilation duct 15 for purification and regulation. This regulates the cleanliness of the air entering the ventilation duct 15, thereby improving the quality of the air exhausted through the air outlet 13.

[0110] In specific examples, such as Figure 5 As shown, the air handling unit 60 includes a purification bracket 61 and a purification screen 62. The purification bracket 61 is fixedly connected inside the housing assembly 10, and the purification screen 62 is detachably disposed inside the purification bracket 61. The purification bracket 61 is used to support the purification screen 62, and the purification screen 62 is used to purify the air flowing through it to improve the quality of the air discharged through the air outlet 13.

[0111] Optionally, the purification net 62 may be a HEPA (High efficiency particulate air filter) purification net to improve the purification quality of the purification net 62, thereby ensuring the quality of the air discharged through the air outlet 13.

[0112] Therefore, this application provides an air handling component 60 within the ventilation duct 15, so that the fresh air component 100 has at least one of the functions of temperature regulation, humidity regulation, odor regulation, or air quality regulation, thereby further increasing the functionality of the fresh air component 100. This allows the fresh air component 100 of this application to have the advantages of multiple functions, simple structure, small size, high assembly efficiency, and low cost.

[0113] Optionally, when the air handling unit 60 is located in the ventilation duct 15, the air handling unit 60 can be located near the fresh air inlet 11 and the indoor air inlet 12, or near the air outlet 13 and the inlet of the exhaust duct 14. The specific location of the air handling unit 60 is not limited, as long as it can handle the air flowing through the ventilation duct 15.

[0114] Optionally, when the second switching valve 40 is in the fourth position, the air handling unit 60 can be switched to the closed state, that is, when the ventilation duct 15 is connected to the exhaust duct 14, the air entering the fresh air component 100 will be directly discharged to the outside, which will not affect the indoor users. At this time, the air handling unit 60 is controlled to close to reduce the number of times the air handling unit 60 is used and reduce the frequency of use of the air handling unit 60, thereby extending the service life of the air handling unit 60.

[0115] It should be noted that when the fresh air component 100 of this application is equipped with an air handling unit 60, the circulation function of the fresh air component 100 is turned on. When the fresh air component 100 is working, it can repeatedly and multiple times adjust the temperature, humidity, odor or purify the indoor air, thereby improving the comfort and quality of the indoor air and thus improving the user experience.

[0116] The air conditioner 1000 of the present invention is described below with reference to the accompanying drawings.

[0117] like Figure 3 As shown, the air conditioner 1000 according to an embodiment of the present invention includes a heat exchange component 200 and a fresh air component 100.

[0118] Among them, such as Figure 1 As shown, the heat exchange component 200 includes a heat exchange device 210 and an air supply device 220, with the air supply device 220 directing airflow through the heat exchange device 210. With this configuration, when the air conditioner 1000 is in use, the air supply device 220 drives external airflow into the heat exchange device 210, which then exchanges heat with the airflow. The heat-exchanged airflow is then discharged to the outside of the air conditioner 1000, thus enabling the air conditioner 1000 of this application to regulate air temperature.

[0119] The fresh air component 100 is the aforementioned fresh air component 100, and the fresh air component 100 and the heat exchange component 200 can either have separate air outputs or have mixed air outputs.

[0120] As can be seen from the above structure, the air conditioner 1000 of the present invention, by adopting the aforementioned fresh air component 100, enables the air conditioner 1000 of the present application to have functions such as fresh air, circulation, exhaust, and purification at the same time, without increasing the number of parts of the air conditioner 1000 too much. Thus, the air conditioner 1000 can take into account the advantages of multiple functions, high assembly efficiency, and low cost.

[0121] Optionally, such as Figure 1 and Figure 2 As shown, the air conditioner housing 300 has a heat exchange outlet 320 in the middle, and the airflow after heat exchange by the heat exchange device 210 is suitable to be discharged from the heat exchange outlet 320; the air conditioner housing 300 has fresh air outlets 310 on the left and right sides, and the airflow after being processed by the fresh air component 100 is suitable to be discharged from the fresh air outlet 310, so that the fresh air component 100 and the heat exchange component 200 of this application can each discharge air separately.

[0122] In other examples, a heat exchange outlet 320 may be provided only in the middle of the air conditioner housing 300. The airflow after heat exchange by the heat exchange device 210 and the airflow after treatment by the fresh air component 100 are both discharged through the heat exchange outlet 320, thereby making the fresh air component 100 and the heat exchange component 200 of this application mix and discharge air.

[0123] The air conditioner 1000 of this application is described in detail below with reference to the accompanying drawings. The air conditioner 1000 can be a wall-mounted air conditioner or a floor-standing air conditioner.

[0124] Among them, such as Figure 3 As shown, the air conditioner 1000 includes a fresh air component 100, a heat exchange component 200, and an air conditioner housing 300. The fresh air component 100 and the heat exchange component 200 are both disposed inside the air conditioner housing 300. The heat exchange component 200 includes a heat exchange device 210 and an air supply device 220. The air supply device 220 causes airflow to pass through the heat exchange device 210, and the heat exchange device 210 is used to exchange heat on the passing airflow.

[0125] like Figure 1 and Figure 2 As shown, the air conditioner housing 300 has a heat exchange outlet 320 in the middle, and the airflow after heat exchange by the heat exchange device 210 is suitable to be discharged from the heat exchange outlet 320; the air conditioner housing 300 has fresh air outlets 310 on the left and right sides, and the airflow after being processed by the fresh air component 100 is suitable to be discharged from the fresh air outlet 310, so that the fresh air component 100 and the heat exchange component 200 of this application can each discharge air separately.

[0126] The fresh air component 100 includes a housing assembly 10, a fan wheel 20, a first switching valve 30, a second switching valve 40, a temperature control component 50, an air handling component 60, and a fan 70. The fan wheel 20, the first switching valve 30, the second switching valve 40, the temperature control component 50, the air handling component 60, and the fan 70 are all housed within the housing assembly 10. The housing assembly 10 has a fresh air inlet 11, an indoor air inlet 12, and an air outlet 13. The housing assembly 10 also has an exhaust duct 14, a ventilation duct 15, a first duct 16, and a second duct 17. The fresh air inlet 11 is connected to the ventilation duct 15 through the first duct 16, and the indoor air inlet 12 is connected to the ventilation duct 15 through the second duct 17. The side wall of the first duct 16 has a connecting port 161, which is connected to the exhaust duct 14.

[0127] The impeller 20 is used to allow air to enter the ventilation duct 15 through the fresh air inlet 11 or the indoor air inlet 12, and to exit the air through the exhaust duct 14 or the air outlet 13.

[0128] The first switching valve 30 is rotatably disposed on the housing assembly 10 so that the first switching valve 30 can reciprocate between a first position and a second position, wherein, for example Figure 5 As shown, when the first switching valve 30 is in the first position, the first switching valve 30 connects the ventilation duct 15 to the fresh air inlet 11 and blocks it from the indoor air inlet 12; as Figure 6 and Figure 7 As shown, when the first switching valve 30 is in the second position, the first switching valve 30 blocks the ventilation duct 15 from the fresh air inlet 11 and connects it to the indoor air inlet 12.

[0129] The second switching valve 40 is rotatably disposed on the housing assembly 10 so that the second switching valve 40 can reciprocate between a third position and a fourth position, wherein, for example Figure 5 and Figure 7 As shown, when the second switching valve 40 is in the third position, the second switching valve 40 connects the ventilation duct 15 to the air outlet 13 and blocks it from the exhaust duct 14; as Figure 6 As shown, when the second switching valve 40 is in the fourth position, the second switching valve 40 blocks the ventilation duct 15 from the air outlet 13 and connects it to the exhaust duct 14.

[0130] Temperature control component 50 is located in the refrigerant circulation system and within the first air duct 16 and the second air duct 17; air handling component 60 is located within the ventilation duct 15 and is positioned close to the first air duct 16 and the second air duct 17. Air handling component 60 includes a purification bracket 61 and a purification screen 62. The purification bracket 61 is fixedly connected to the housing assembly 10, and the purification screen 62 is detachably located within the purification bracket 61. The purification screen 62 is used to purify the air flowing through it.

[0131] The three functions of the fresh air component 100 of this application are described in detail below with reference to the accompanying drawings.

[0132] First, the fresh air component 100 of this application has the function of introducing fresh air. When introducing fresh air, such as Figure 5 As shown, the first switching valve 30 is rotated to the first position so that the ventilation duct 15 is connected to the fresh air inlet 11 and blocked from the indoor air inlet 12. The second switching valve 40 is rotated to the third position so that the ventilation duct 15 is connected to the air outlet 13 and blocked from the exhaust duct 14. At this time, the fan 70 drives the impeller 20 to work so as to introduce outdoor air into the ventilation duct 15 through the fresh air inlet 11 and exhaust the introduced air to the room through the air outlet 13, thereby realizing the fresh air function of the fresh air component 100 of this application.

[0133] Secondly, the fresh air component 100 of this application has an exhaust function, which can be used to exhaust stale air from the room when necessary. Figure 6 As shown, the first switching valve 30 is rotated to the second position to block the ventilation duct 15 from the fresh air inlet 11 and connect it to the indoor air inlet 12. The second switching valve 40 is rotated to the fourth position to block the ventilation duct 15 from the air outlet 13 and connect it to the exhaust duct 14. At this time, the fan 70 drives the impeller 20 to work, so as to introduce indoor air into the ventilation duct 15 through the indoor air inlet 12 and exhaust the introduced air to the outside through the exhaust duct 14 and the fresh air inlet 11 in sequence, thereby realizing the exhaust function of the fresh air component 100 of this application.

[0134] Third, the fresh air component 100 of this application has a circulation function, which allows for the circulation of indoor air when needed, such as... Figure 7 As shown, the first switching valve 30 is rotated to the second position to block the ventilation duct 15 from the fresh air inlet 11 and connect it to the indoor air inlet 12. The second switching valve 40 is rotated to the third position to connect the ventilation duct 15 to the air outlet 13 and block it from the exhaust duct 14. At this time, the fan 70 drives the impeller 20 to work, so as to introduce indoor air into the ventilation duct 15 through the indoor air inlet 12 and exhaust the introduced air out of the air outlet 13 into the room, thereby realizing the circulation function of the fresh air component 100 of this application.

[0135] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection.
