[0061] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0062] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0063] Hereinafter, with reference to the accompanying drawings, a fresh air component 100 according to a first aspect embodiment of the present invention will be described.

[0064] like Figures 1-5 As shown, the fresh air component 100 includes: a housing assembly 1 and a fan assembly 2.

[0065] The fan assembly 2 is housed within the housing assembly 1. The housing assembly 1 has a fresh air inlet 105 and a fresh air outlet 106, which are connected. The fresh air inlet 105 is adapted to connect to the outside, and the fresh air outlet 106 is adapted to connect to the inside. The fresh air outlet 106 includes two side outlets 1062 formed on the left and right sides of the housing assembly 1 and a front outlet 1061 formed on the front side of the housing assembly. (Refer to...) Figure 1 and Figure 2 A side outlet 1062 is formed on the left side of the housing assembly 1, a side outlet 1062 is formed on the right side of the housing assembly 1, and a front outlet 1061 is formed on the front side of the housing assembly 1.

[0066] When the fan assembly 2 is operating, outdoor air can enter the housing assembly 1 through the fresh air inlet 105, and then be discharged into the room through the side outlet 1062 and the front outlet 1061. This enables the introduction of outdoor fresh air into the room. Furthermore, since the housing assembly 1 has fresh air outlets 106 on its left, right, and front sides, air can be discharged into the room from different directions, creating a three-dimensional airflow effect. This improves both the efficiency of fresh air delivery and the uniformity of indoor fresh air, thus enhancing the comfort of the fresh air section.

[0067] According to the embodiments of the present invention, the fresh air component 100 provides side outlets 1062 on the left and right sides of the housing assembly 1 and a front outlet 1061 on the front side of the housing, so that the fresh air introduced from the outside can be discharged into the room from different directions. On the one hand, it improves the air outlet efficiency of the fresh air, and on the other hand, it improves the uniformity of the fresh air in the room, thereby improving the comfort of the fresh air component 100.

[0068] According to some embodiments of the present invention, the opening of the front outlet 1061 faces downward. This prevents the airflow exiting the front outlet 1061 from blowing directly onto the human body, further improving the comfort of the fresh air component 100.

[0069] Specifically, refer to Figure 1 and combined Figure 3 and Figure 5 The housing assembly 1 is provided with an air guide plate 13 extending in the vertical direction. It can be understood that the air guide plate 13 can extend vertically or extend obliquely in the vertical direction. The upper end of the air guide plate 13 is connected to the housing assembly 1, and the lower end of the air guide plate 13 is spaced apart from the housing assembly 1 to form an outlet. The structure is simple and easy to process.

[0070] According to some embodiments of the present invention, a grille 14 is provided at the side outlet 1062, and the grille 14 is detachably connected to the housing assembly 1. This facilitates the installation and removal of the grille 14, thereby making it convenient for the user to clean, replace, and maintain the grille 14.

[0071] In some embodiments of the invention, the grille 14 can be detachably connected to the housing assembly 1 by screws or snap-fit ​​components. For example, see reference... Figures 7-9 The grille 14 is detachably connected to the housing assembly 1 via a snap-fit ​​assembly. The snap-fit ​​assembly includes snaps 151 and slots 152 that mate with the snaps 151. Specifically, multiple snaps 151 can be spaced apart circumferentially on the grille 14, and multiple slots 152 that mate with the snaps 151 can be spaced apart circumferentially on the side openings. The structure is simple and easy to assemble and disassemble.

[0072] Furthermore, one of the grille 14 and the housing assembly 1 may be provided with a positioning buckle 161, and the other of the grille 14 and the housing assembly 1 may be provided with a positioning groove 162 that cooperates with the positioning buckle 161. During assembly, the grille 14 can be initially positioned by the engagement of the positioning buckle 161 and the positioning groove 162, and then the grille 14 can be assembled to the side outlet 1062 by screws or snap fasteners 151, which reduces the assembly difficulty and improves the assembly efficiency.

[0073] According to some embodiments of the present invention, the side wall of the side outlet 1062 is provided with a handle 17 recessed in a direction away from the center of the side outlet 1062. When removing the grille 14 from the side outlet 1062, the user inserts a removal tool or finger into the handle 17 to remove the grille 14 from the side outlet 1062. This reduces the difficulty of removing the grille 14 and improves the removal efficiency.

[0074] According to some embodiments of the present invention, the housing assembly 1 has a first chamber 101, a second chamber 102, and a third chamber 103. The housing assembly 1 has a first vent 104, a fresh air inlet 105, and a fresh air outlet 106. The first vent 104 communicates with the first chamber 101, the fresh air inlet 105 communicates with the second chamber 102, and the fresh air outlet 106 communicates with the third chamber 103. The fresh air inlet 105 is adapted to communicate with the outside, and both the first vent 104 and the fresh air outlet 106 are adapted to communicate with the interior. The fan assembly 2 is disposed in the first chamber 101. In this way, air can enter the first chamber 101 through the first vent 104, air can enter and exit the second chamber 102 through the fresh air inlet 105, and air can flow out of the third chamber 103 through the fresh air outlet 106.

[0075] like Figures 3-5 As shown, the fresh air component 100 also includes a first valve assembly 3, which is switchable between a first open state and a first closed state. In the first open state, the first valve assembly 3 connects the outlet of the first chamber 101 to the third chamber 103 and isolates the outlet of the first chamber 101 from the second chamber 102. In the first closed state, the first valve assembly 3 isolates the outlet of the first chamber 101 from the third chamber 103 and connects the outlet of the first chamber 101 to the second chamber 102. Thus, when the fan assembly 2 is operating, as... Figure 3 and Figure 4 As shown, in the first open state, the airflow discharged from the first chamber 101 can flow to the third chamber 103, but cannot flow to the second chamber 102, as... Figure 5 As shown, in the first closed state, the airflow discharged from the first chamber 101 can flow to the second chamber 102, but cannot flow to the third chamber 103.

[0076] like Figures 3-5 As shown, the fresh air component 100 also includes a second valve assembly 4, which is switchable between a second open state and a second closed state. In the second open state, the second valve assembly 4 connects the inlet of the first chamber 101 to the second chamber 102; in the second closed state, the second valve assembly 4 isolates the inlet of the first chamber 101 from the second chamber 102. Thus, when the fan assembly 2 is operating, such as... Figure 3 As shown, in the second open state, the first chamber 101 can draw airflow from the second chamber 102, such as... Figure 5 As shown, in the second closed state, the first chamber 101 cannot introduce airflow from the second chamber 102.

[0077] Therefore, the fresh air component 100 according to the embodiments of the present invention can have at least the following three working modes.

[0078] In the first working mode, such asFigure 3 As shown, the first valve assembly 3 is in the first open state, and the second valve assembly 4 is in the second open state. At this time, the inlet of the first chamber 101 is connected to the second chamber 102, and the outlet of the first chamber 101 is connected to the third chamber 103, but the outlet of the first chamber 101 is not connected to the second chamber 102. When the fan assembly 2 is working, outdoor air can enter the second chamber 102 through the fresh air inlet 105, then enter the first chamber 101 from the second chamber 102, and then be discharged from the first chamber 101 to the third chamber 103, and finally be discharged into the room through the fresh air outlet 106. Thus, the function of introducing outdoor fresh air from the outside to the inside can be realized.

[0079] In the second operating mode, the first valve assembly 3 is in the first open state, and the second valve assembly 4 is in the second closed state. At this time, the inlet of the first chamber 101 is not connected to the second chamber 102, and the outlet of the first chamber 101 is connected to the third chamber 103, while the outlet of the first chamber 101 is not connected to the second chamber 102. When the fan assembly 2 is operating, indoor air can enter the first chamber 101 through the first vent 104, then enter the third chamber 103 from the first chamber 101, and finally be exhausted into the room through the fresh air outlet 106. This achieves an internal air circulation function, drawing air from the room and then exhausting it back into the room.

[0080] In the third working mode, such as Figure 5 As shown, the first valve assembly 3 is in a first closed state, and the second valve assembly 4 is in a second closed state. At this time, the inlet of the first chamber 101 is not connected to the second chamber 102, the outlet of the first chamber 101 is connected to the second chamber 102, and the outlet of the first chamber 101 is not connected to the third chamber 103. When the fan assembly 2 is working, indoor air can enter the first chamber 101 through the first vent 104, then enter the second chamber 102 from the first chamber 101, and finally be discharged to the outside through the fresh air inlet 105. Thus, the exhaust function of drawing air from the room and then discharging it to the outside can be achieved, thereby achieving the effect of discharging sludge outdoors.

[0081] As described above, the first vent 104 can serve as both the air inlet for the internal circulation function and the air inlet for the exhaust function; the fresh air inlet 105 can serve as both the air inlet for the fresh air function and the air outlet for the exhaust function; and the fresh air outlet 106 can serve as both the air outlet for the fresh air function and the air outlet for the internal circulation function. Furthermore, it should be noted that under the fresh air function, the path of airflow through the housing assembly 1 is called the fresh air channel; under the internal circulation function, the path of airflow through the housing assembly 1 is called the internal circulation channel; and under the exhaust function, the path of airflow through the housing assembly 1 is called the exhaust channel. In some embodiments of the present invention, air handling modules are installed within the fresh air channel and the internal circulation channel, or along paths connecting to the fresh air channel and the internal circulation channel, to achieve pre-treatment of the air before its discharge into the room. Therefore, the fresh air channel and the internal circulation channel are defined as air handling channels.

[0082] Therefore, according to the embodiment of the present invention, the fresh air component 100, by setting two valve components, a first valve component 3 and a second valve component 4, and matching the different on / off states of these two valve components, can achieve the simultaneous opening of the air handling passage and closing of the exhaust passage, and vice versa. In other words, by setting two valve components, the air handling passage and the exhaust passage are mutually exclusive. Through the design of the two valve components, it is possible to achieve the simultaneous opening of the air handling passage and closing of the exhaust passage, and vice versa. By switching the on / off states of the two valve components, the airflow direction inside the housing component 1 can be changed, thereby achieving different functions.

[0083] In short, the fresh air component 100 according to an embodiment of the present invention, by designing the inner cavity of the housing assembly 1 as described above and providing a first valve assembly 3 and a second valve assembly 4 having the aforementioned functions, can at least achieve switching between internal circulation function, fresh air function, and exhaust function, thereby meeting different user needs. Furthermore, the first valve assembly 3 can control the outlet of the first chamber 101 to selectively connect with one of the third chamber 103 and the second chamber 102, or in other words, ensure the mutual exclusion of the outlet of the first chamber 101 connecting with the third chamber 103 and the second chamber 102, thereby reducing the number of valves required, simplifying the structure, reducing costs, and improving assembly efficiency.

[0084] In some embodiments of the present invention, such as Figures 5-7As shown, the fresh air component 100 also includes an air handling unit 5, which is located in the third chamber 103 and upstream of the fresh air outlet 106. That is, the airflow entering the third chamber 103 is first processed by the air handling unit 5 before being discharged from the fresh air outlet 106. This achieves the air handling effect under both internal circulation and fresh air functions, ensuring that the air entering the room meets the user's needs. Furthermore, since the airflow does not pass through the third chamber 103 under exhaust function and is not processed by the air handling unit 5, the use of the air handling unit 5 is avoided when it is not needed, reducing its utilization rate and extending its service life. In addition, since the air handling unit 5 is located in the third chamber 103, it has a larger storage space, facilitating the installation of larger, more numerous, or more types of air handling units 5, thereby improving the air handling effect and simplifying the design for disassembly and assembly of the air handling unit 5.

[0085] The specific configuration of the air handling device 5 is not limited. For example, it may include a purification module (such as a high-efficiency filter module, a formaldehyde removal module, a VOC removal module, a dust removal module, an allergen removal module, a disinfection and sterilization module, or an odor removal module), a humidification module, etc., which are not limited here. In addition, it should be noted that the present invention is not limited thereto. In other embodiments of the present invention, the air handling device 5 may not be located in the third chamber 103. For example, it may be located in the first chamber 101 and / or the second chamber 102, or it may be located outside the housing assembly 1, for example, downstream of the fresh air outlet 106, etc., which will not be elaborated here.

[0086] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the fresh air component 100 also includes a third valve assembly 6, which is switchable between a third open state and a third closed state. In the third open state, the first vent 104 is open, and in the third closed state, the first vent 104 is closed. That is, only in the third open state can indoor air enter the first chamber 101 through the first vent 104; in the third closed state, indoor air can no longer enter the first chamber 101 through the first vent 104. Thus, in the fresh air function, the third valve assembly 6 can be switched to the third closed state, allowing only outdoor air to supply air to the first chamber 101, ensuring sufficient fresh air intake. In the internal circulation and exhaust functions, the third valve assembly 6 can be switched to the third open state, thus meeting the requirement of supplying air from indoors to the first chamber 101. It should be noted that the structure and location of the third valve assembly 6 are not limited, as long as the above requirements are met. For example, it can be an electrically operated door, an electrically operated air guide plate, a manually operated door, etc., which will not be elaborated here.

[0087] In some embodiments of the present invention, such as Figures 3-5 As shown, the first chamber 101 includes a first sub-chamber 1011, a second sub-chamber 1012, and a third sub-chamber 1013. The fan assembly 2 is located in the second sub-chamber 1012, which connects the first sub-chamber 1011 and the third sub-chamber 1013. The first valve assembly 3 is located between the third sub-chamber 1013 and the third chamber 103, and the second valve assembly 4 is located between the first sub-chamber 1011 and the second chamber 102. Therefore, the structure of the first chamber 101 is rationally designed, ensuring that the positions of the first valve assembly 3, the second valve assembly 4, and the fan assembly 2 do not interfere with each other, thus facilitating assembly and ensuring reliable operation of the first valve assembly 3, the second valve assembly 4, and the fan assembly 2.

[0088] In some embodiments of the present invention, such as Figures 3-5 As shown, the fan assembly 2 includes a centrifugal fan 21. A first sub-chamber 1011 is located behind the second sub-chamber 1012, and a third sub-chamber 1013 is located above the first and second sub-chambers 1011 and 1012. Therefore, the design of the first chamber 101 meets the operating requirements of the centrifugal fan 21, allowing it to draw air from the rear and exhaust air from the top. This increases ventilation volume and meets requirements for large fresh air volumes. Furthermore, by placing the third sub-chamber 1013 above the first and second sub-chambers 1011 and placing the first sub-chamber 1011 behind the second sub-chamber 1012, space is fully utilized, ensuring ample installation space for both the first valve assembly 3 and the second valve assembly 4, and preventing interference between them. It should be noted that the directional terms used herein, such as upper, lower, left, right, front, and rear, are for simplification and clarity and are based on the accompanying drawings; they should not be construed as limiting the scope of this application.

[0089] In some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the second chamber 102 is located behind the first sub-chamber 1011 and the third sub-chamber 1013. The bottom of the third sub-chamber 1013 has a first connecting port 1071, which communicates with the upper end of the second sub-chamber 1012. The rear side of the third sub-chamber 1013 has a second connecting port 1072, which communicates with the upper end of the second chamber 102. Thus, the connection between the second sub-chamber 1012 and the third sub-chamber 1013 can be achieved simply and effectively, and the connection between the third sub-chamber 1013 and the second chamber 102 can also be achieved simply and effectively. This makes the housing assembly 1 according to the embodiment of the present invention compact, small, and with a short airflow path, reducing airflow loss and energy consumption.

[0090] In some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the first chamber 101 and the third chamber 103 are connected by a first through port 1081 located at the top of the third sub-chamber 1013. The first valve assembly 3 includes a first actuator and a plurality of first baffles 32a and second baffles 32b. The second baffles 32b are located on one side of the plurality of first baffles 32a adjacent to the second communication port 1072 (e.g., Figure 3 (The rear side of multiple first baffles 32a), multiple first baffles 32a and second baffles 32b are arranged sequentially in the front-back direction.

[0091] The second baffle, 32b, is located on one side of the plurality of first baffles 32a adjacent to the second communication port 1072. The second baffle 32b and each first baffle 32a are pivotally connected to the housing assembly 1, and the pivot axis of each first baffle 32a and second baffle 32b extends in the left-right direction. The first actuator is used to drive the plurality of first baffles 32a and second baffles 32b to rotate, such as... Figure 3 As shown, in the first closed state, the main body portions 321 of the multiple first baffles 32a and second baffles 32b together block the first passage 1081, as... Figure 5 As shown, in the first open state, multiple first baffles 32a and second baffles 32b together open the first passage 1081, and the second baffle 32b closes the second communication port 1072.

[0092] Therefore, in this embodiment, both the first passage 1081 and the second communication port 1072 are outlets of the first chamber 101. In the first open state, such as Figure 4 As shown, the first valve assembly 3 opens the first passage port 1081 and closes the second communication port 1072, as... Figure 5a As shown, in the first closed state, the first valve assembly 3 closes the first passage port 1081 and opens the second communication port 1072. Thus, the structure of the first valve assembly 3 is simple, and it can easily and effectively realize the selective connection between the outlet of the first chamber 101 and one of the third chamber 103 and the second chamber 102, thereby saving the number of valves used here, simplifying the structure, reducing costs, and improving assembly efficiency.

[0093] Reference Figures 3-5 and combined Figure 3The second baffle 32b includes a body portion 321, an extension portion 322, and a connecting portion 323. The body portion 321 and the extension portion 322 are respectively connected to both ends of the connecting portion 323. The extension portion 322 can be parallel to the body portion 321. In the first open state, the body portion 321 and the extension portion 322 of the second baffle 32b together close the second communication port 1072. In the first closed state, the body portion 321 of the second baffle 32b and multiple first baffles 32a are located on the same horizontal plane, jointly blocking the first passage port 1081. At this time, the extension portion 322 of the second baffle 32b can be located below the first baffles 32a. This facilitates the second baffle 32b cooperating with the first baffles 32a to open and close the first passage port 1081, and also facilitates the second baffle 32b closing the second communication port 1072.

[0094] Optionally, the structure of the main body 321 can be the same as that of the first baffle 32a. This design is simple and easy to manufacture.

[0095] According to some embodiments of the present invention, the second communication port 1072 includes a first sidewall 1072a and a second sidewall 1072b disposed opposite to each other. The pivot axis of the second baffle 32b is disposed adjacent to the first sidewall 1072a, and the inner wall surface of the second sidewall 1072b is formed as an arcuate surface convex away from the first sidewall 1072a. Therefore, by setting the inner wall surface of the second sidewall 1072b as an arcuate surface convex away from the first sidewall, interference of the second sidewall 1072b with the stroke of the second baffle 32b can be avoided when the second baffle 32b rotates, increasing the rotatable angle of the second baffle 32b, thereby increasing the area of ​​the second communication port 1072, increasing the airflow rate, reducing the airflow resistance, and reducing airflow noise.

[0096] In some embodiments of the present invention, such as Figure 5 As shown, the first chamber 101 and the second chamber 102 are connected through a second passage 1082 located at the rear of the first sub-chamber 1011. The second valve assembly 4 includes a second actuator and a plurality of third baffles 41. The plurality of third baffles 41 are arranged sequentially in the vertical direction. Each third baffle 41 is pivotally connected to the housing assembly 1, and the pivot axis of each third baffle 41 extends in the horizontal direction. The second actuator is used to drive the plurality of third baffles 41 to rotate. In the second closed state, the plurality of third baffles 41 together block the second passage 1082. In the second open state, the plurality of third baffles 41 together open the second passage 1082.

[0097] Therefore, in this embodiment, the second access port 1082 is the entrance to the first chamber 101, and in the second open state, such as Figure 4 As shown, the second valve assembly 4 opens the second passage port 1082, as... Figures 1-3 andFigures 6-8 As shown, in the second closed state, the second valve assembly 4 closes the second passage 1082. Thus, the second valve assembly 4 has a simple structure and can easily and effectively achieve the connection and blockage between the inlet of the first chamber 101 and the second chamber 102.

[0098] In some embodiments of the present invention, at least one of the first valve assembly 3 and the second valve assembly 4 includes: a driver, a connecting rod, and a plurality of baffles. The plurality of baffles are arranged sequentially along the length of the connecting rod, and each baffle is connected to the connecting rod. The driver drives one of the baffles to rotate, and one of the baffles drives the remaining baffles to rotate through the connecting rod. Thus, the valve assembly has a simple structure and is easy to control.

[0099] For example, in some embodiments of the present invention, the first valve assembly 3 may include a first actuator, a first connecting rod, a plurality of first baffles 32a and second baffles 32b. The plurality of first baffles 32a and second baffles 32b are arranged sequentially along the length direction of the first connecting rod, and each first baffle 32a and second baffle 32b is connected to the first connecting rod. The first actuator drives one of the first baffles 32a or drives the second baffle 32b to rotate. The first baffle 32a or the second baffle 32b drives the remaining baffles (first baffles 32a or second baffles 32b) to rotate through the first connecting rod. The second baffle 32b is located on one side of the plurality of first baffles 32a adjacent to the second communication port 1072. The second baffle 32b includes a body portion 321 and an extension portion 322, and the extension portion 322 is connected to one end of the body portion 321. Thus, the first valve assembly 3 has a simple structure and is easy to control the switching between the first open state and the first closed state. For example, in a specific embodiment of the present invention, in the first closed state, the body portions 321 of the plurality of first baffles 32a and second baffles 32b are located on the same plane. The body portion 321 of the second baffle 32b is connected, overlapped, or has only a small airflow gap with the adjacent first baffle 32a and two adjacent first baffles 32a. In the first open state, the body portions 321 of the plurality of first baffles 32a and second baffles 32b are parallel to each other. Thus, it can be ensured that the distance between the second baffle 32b and the adjacent first baffle 32a and two adjacent first baffles 32a is large, thereby improving the airflow throughput, reducing wind resistance, and reducing energy consumption.

[0100] For example, in some embodiments of the present invention, the second valve assembly 4 may include a second actuator, a second connecting rod, and a plurality of third baffles 41. The plurality of third baffles 41 are arranged sequentially along the length direction of the second connecting rod, and each third baffle 41 is connected to the second connecting rod. The second actuator drives one of the third baffles 41 to rotate, and the third baffle 41 drives the remaining third baffles 41 to rotate through the second connecting rod. Thus, the structure of the second valve assembly 4 is simple and easy to control the switching between the second open state and the second closed state. For example, in a specific example of the present invention, in the second closed state, the plurality of third baffles 41 are located on the same plane, and adjacent third baffles 41 are connected, overlapped, or have only a small airflow gap. In the second open state, the plurality of third baffles 41 are parallel to each other, and the plane on which each third baffle 41 is located is perpendicular to the extension direction of the second connecting rod. Thus, the spacing between adjacent third baffles 41 can be large, improving the airflow throughput, reducing wind resistance, and reducing energy consumption.

[0101] It should be noted that the specific structural form, size, position and movement mode of the first valve assembly 3, the second valve assembly 4 and the third valve assembly 6 according to the embodiments of the present invention are not limited to the above description, and can be specifically selected according to actual requirements, as long as the above functional requirements can be met.

[0102] In some embodiments of the present invention, such as Figure 3 As shown, the second chamber 102 is located behind the first chamber 101, the third chamber 103 is located above the first sub-chamber 1011, the fresh air outlet 106 includes a front outlet 1061 located above the front side of the third chamber 103 and two side outlets 1062 located on the left and right sides of the third chamber 103 respectively, the first ventilation opening 104 includes two side openings 1041 located on the left and right sides of the first chamber 101 respectively, and the fresh air inlet 105 is one or more and located behind the second chamber 102.

[0103] Therefore, as described above, the first ventilation opening 104 can serve as the air inlet for the internal circulation function and the air inlet for the exhaust function, the fresh air inlet 105 can serve as the air inlet for the fresh air function and the air outlet for the exhaust function, and the fresh air outlet 106 can serve as the air outlet for the fresh air function and the air outlet for the internal circulation function. Thus, by designing the first ventilation opening 104, the fresh air inlet 105, and the fresh air outlet 106 as described above, it can be ensured that the air outlet and the air inlet are far apart, avoiding the problem of backflow, and it can maximize the range and volume of air outlet, as well as maximize the range and volume of air inlet.

[0104] Of course, the present invention is not limited to this. The number and location of the first ventilation opening 104, the fresh air inlet 105 and the fresh air outlet 106 can be adjusted according to the actual situation, as long as the ventilation requirements of the above functions are met. This will not be elaborated here.

[0105] It should be noted that the specific configuration of the housing assembly 1 according to the embodiments of the present invention is not limited, for example... Figures 5-7 As shown, the housing assembly 1 may include a front housing 11 and a rear housing 12. A front outlet 1061 may be formed on the upper part of the front housing 11. Side outlets 1062 are formed on the upper parts of the left and right sides of the rear housing 12, and multiple fresh air inlets 105 are spaced apart in the vertical direction on the lower part of the rear housing 12. Side openings 1041 are provided on the lower parts of the left and right sides of the rear housing, and a fan mounting opening is provided on the lower side of the front housing 11. Therefore, the housing assembly 1 has a simple structure, is easy to process and assemble, and can easily and effectively achieve sealing of non-open areas.

[0106] According to some embodiments of the present invention, a mounting bracket 18 is provided in the third chamber 103. The mounting bracket 18 includes a mounting base 181 and a partition 182. The mounting base 181 is connected to the lower part of the partition 182 and is used to mount the air handling unit 5. The partition 182 and the inner wall of the housing assembly 1 define a mounting groove 183 for mounting the electrical control box. Thus, the air handling unit 5 can be mounted on the mounting base 181, improving the installation stability of the air handling unit 5 and the air handling effect. Furthermore, the electrical control box can be installed inside the fresh air component 100, making the structure of the air conditioner 1000 more compact and rational.

[0107] Reference Figure 10 , Figure 9 and Figure 10 The partition 182 can extend generally in a vertical direction. The air handling unit 5 can be configured to be detachably installed. For example, the upper front shell of the housing assembly 1 can have a disassembly port 1110, and the mounting base 181 is provided with a slide rail 1120. The air handling unit 5 can be inserted into the slide rail 1120 through the disassembly port 1110, or removed from the disassembly port 1110 along the slide rail 1120, thereby facilitating the disassembly and assembly of the air handling unit 5, so as to facilitate the cleaning, replacement or maintenance of the air handling unit 5, and to facilitate the processing of the slide rail 1120 and the disassembly port 1110.

[0108] Optionally, the air handling unit 5 can be horizontally mounted on the mounting base 181. This reduces the space occupied by the air handling unit 5, thereby increasing the space of the mounting slot 183 to meet the installation requirements of the electrical control box.

[0109] According to some embodiments of the present invention, a primary filter device 19 is provided inside the housing assembly 1. The primary filter device 19 is located downstream of the first vent 104 and downstream of the fresh air inlet 105. Optionally, the primary filter device 19 is a filter screen. Thus, the air entering the housing assembly 1 through the first vent 104 and the fresh air inlet 105 can be preliminarily filtered by the primary filter device 19, improving air cleanliness, reducing the burden on the air handling unit 5, extending the service life of the air handling unit 5, and reducing operating costs.

[0110] Optionally, the primary filter 19 is detachably mounted on the housing assembly 1. This facilitates the cleaning, replacement, or maintenance of the primary filter 19.

This improves both the fresh air outlet efficiency and the uniformity of the indoor fresh air, thereby enhancing the comfort of the air conditioner 1000.

[0114] According to an embodiment of the present invention, the air conditioner 1000, by providing a fresh air component 100, can have internal circulation, fresh air, and exhaust functions, thereby meeting different user needs.
