[0053] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0054] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0055] Hereinafter, the fresh air component 100 according to the first embodiment of the present invention will be described with reference to the accompanying drawings.

[0056] like Figure 1 As shown, the fresh air component 100 may include a housing assembly 1, and a fan chamber 101 may be provided in the housing assembly 1. Figure 1 As shown, the fresh air component 100 may include a fan assembly 2, and the fan chamber 101 is used to set the fan assembly 2, that is, at least part of the fan assembly 2 is arranged in the fan chamber 101. When the fan assembly 2 is working, the air outside the fan chamber 101 can enter the fan chamber 101 through the inlet of the fan chamber 101, and the air entering the fan chamber 101 can flow from the inlet of the fan chamber 101 to the outlet of the fan chamber 101, and then be discharged from the fan chamber 101 through the outlet of the fan chamber 101.

[0057] like Figure 1As shown, the housing assembly 1 is provided with an indoor return air vent 105, which is adapted to communicate with the fan chamber 101. When the indoor return air vent 105 is in communication with the indoor room, the indoor return air vent 105 is in communication with the fan chamber 101, and the fan assembly 2 is operating, if the air pressure in the fan chamber 101 is lower than the air pressure of the indoor environment, the indoor air can enter the fan chamber 101 through the indoor return air vent 105.

[0058] like Figure 1 As shown, a fresh air chamber 102 may be further provided in the housing assembly 1, and an outdoor fresh air outlet 104 may be provided on the housing assembly 1. The outdoor fresh air outlet 104 is adapted to be in communication with the fresh air chamber 102. When the outdoor fresh air outlet 104 is in communication with the outside, the outdoor fresh air outlet 104 is in communication with the fresh air chamber 102, and the fan assembly 2 is working, if the air pressure in the fresh air chamber 102 is lower than the air pressure of the outdoor environment, the outdoor air may enter the fresh air chamber 102 through the outdoor fresh air outlet 104; Figure 3 As shown, if the air pressure in the fresh air chamber 102 is greater than the air pressure of the outdoor environment, the air in the fresh air chamber 102 can be discharged outdoors through the outdoor fresh air outlet 104.

[0059] like Figure 1 As shown, an exhaust chamber 103 can also be provided in the shell component 1, and an indoor air outlet 106 can be provided on the shell component 1. The indoor air outlet 106 is suitable for communicating with the exhaust chamber 103. When the indoor air outlet 106 is connected with the room, the indoor air outlet 106 is connected with the exhaust chamber 103, and the fan component 2 is working, if the air pressure in the exhaust chamber 103 is greater than the air pressure of the indoor environment, the exhaust chamber 103 can be exhausted to the room through the indoor air outlet 106.

[0060] like Figure 1 As shown, the fresh air component 100 includes a first valve assembly 31. When the first valve assembly 31 is in an open state, the fan chamber 101 can exhaust air from the indoor air outlet 106 to the indoor through the exhaust chamber 103. Specifically, the first valve assembly 31 can be switched between an open state and a closed state. Figure 1 and Figure 2 As shown, when the first valve assembly 31 is in an open state, the fan chamber 101 can exhaust air to the indoor room from the indoor air outlet 106 through the exhaust chamber 103. That is, if the fan assembly 2 is working at this time, the fan chamber 101 discharges air to the exhaust chamber 103, and the exhaust chamber 103 exhausts air to the indoor room through the indoor air outlet 106.

[0061] like Figure 3As shown, when the first valve assembly 31 is in a closed state, the fan chamber 101 cannot exhaust air into the room through the exhaust chamber 103 from the indoor air outlet 106, that is, if the fan assembly 2 is working at this time, the fan chamber 101 cannot exhaust air into the exhaust chamber 103, or, although the fan chamber 101 can exhaust air into the exhaust chamber 103, the exhaust chamber 103 cannot exhaust air into the room through the indoor air outlet 106, or, the fan chamber 101 can neither exhaust air into the exhaust chamber 103 nor exhaust air into the room through the indoor air outlet 106.

[0062] like Figure 1 As shown, the fresh air component 100 includes a second valve assembly 32. When the second valve assembly 32 is in an open state, the fan chamber 101 can exhaust air to the fresh air chamber 102. Specifically, the second valve assembly 32 can be switched between an open state and a closed state. Figure 3 As shown, when the second valve assembly 32 is in the open state, the fan chamber 101 can exhaust air to the fresh air chamber 102, that is, if the fan assembly 2 is working at this time, the fan chamber 101 will exhaust air to the fresh air chamber 102. Figure 1 and Figure 2 As shown, when the second valve assembly 32 is in a closed state, the fan chamber 101 cannot exhaust air into the fresh air chamber 102 , that is, if the fan assembly 2 is working at this time, the fan chamber 101 cannot exhaust air into the fresh air chamber 102 .

[0063] like Figure 1 As shown, the fresh air component 100 includes a third valve assembly 33. When the third valve assembly 33 is in an open state, the fan chamber 101 can inhale air from the fresh air chamber 102. Specifically, the third valve assembly 33 can be switched between an open state and a closed state. Figure 1 As shown, when the third valve assembly 33 is in the open state, the fan chamber 101 can inhale air from the fresh air chamber 102, that is, if the fan assembly 2 is working at this time, the air in the fresh air chamber 102 will flow into the fan chamber 101. Figure 2 and Figure 3 As shown, when the third valve assembly 33 is in a closed state, the fan chamber 101 cannot inhale air from the fresh air chamber 102, that is, if the fan assembly 2 is working at this time, the air in the fresh air chamber 102 cannot flow into the fan chamber 101. At this time, if the fan chamber 101 is connected to the indoor return air outlet 105, and the indoor return air outlet 105 is connected to the room, the indoor air can flow into the fan chamber 101 through the indoor return air outlet 105.

[0064] Therefore, the fresh air component 100 according to the embodiment of the present invention can have at least the following three working modes.

[0065] In the first working mode, if Figure 1As shown, the first valve assembly 31 is in an open state, the second valve assembly 32 is in a closed state, and the third valve assembly 33 is in an open state. At this time, if the fresh air chamber 102 is connected to the outside through the outdoor fresh air inlet 104 and the fan assembly 2 is working, the outdoor fresh air will enter the fresh air chamber 102 through the outdoor fresh air inlet 104, then enter the fan chamber 101 through the fresh air chamber 102, and then be discharged from the fan chamber 101 to the exhaust chamber 103, and then be discharged to the room through the indoor air outlet 106. Therefore, the fresh air function of introducing outdoor fresh air from the outside to the room can be achieved.

[0066] In the second working mode, if Figure 2 As shown, the first valve assembly 31 is in an open state, the second valve assembly 32 is in a closed state, and the third valve assembly 33 is in a closed state. At this time, if the fan chamber 101 can draw air from the room through the indoor return air port 105, and the fan assembly 2 is working, the indoor air enters the fan chamber 101 through the indoor return air port 105, and is then discharged from the fan chamber 101 to the exhaust chamber 103, and then discharged into the room through the indoor air outlet 106. Therefore, an internal circulation function of introducing air from the room and then exhausting air into the room can be achieved.

[0067] In the third working mode, if Figure 3 As shown, the first valve assembly 31 is in a closed state, the second valve assembly 32 is in an open state, and the third valve assembly 33 is in a closed state. At this time, if the fan chamber 101 can inhale air from the room through the indoor return air port 105, the fresh air chamber 102 can be connected to the outside through the outdoor fresh air port 104, and the fan assembly 2 is working, the indoor air will enter the fan chamber 101 through the indoor return air port 105, and then be discharged from the fan chamber 101 to the fresh air chamber 102, and the fresh air chamber 102 will discharge the air to the outside through the outdoor fresh air port 104. Therefore, the exhaust function of introducing air from the room and then discharging air to the outside can be realized, thereby achieving the effect of discharging dirty air to the outside.

[0068] As can be seen from the above description, the indoor return air vent 105 can serve as both the air inlet for the internal circulation function and the air inlet for the exhaust function, the outdoor fresh air vent 104 can serve as both the air inlet for the fresh air function and the air outlet for the exhaust function, and the indoor air outlet 106 can serve as both the air outlet for the fresh air function and the air outlet for the internal circulation function. In the fresh air function, the path through which air flows within the housing assembly 1 is called the fresh air channel. In the internal circulation function, the path through which air flows within the housing assembly 1 is called the internal circulation channel. In the exhaust function, the path through which air flows within the housing assembly 1 is called the exhaust channel.

[0069] In some embodiments of the present invention, an air treatment component 4 is provided in the fresh air channel and the internal circulation channel in the shell component 1, or on a path outside the shell component 1 and connected to the fresh air channel and the internal circulation channel, so that the air can be treated first and then discharged into the room. Therefore, the fresh air channel and the internal circulation channel can be defined as air treatment channels. Therefore, according to the fresh air component 100 of the embodiment of the present invention, by providing three groups of valve assemblies, namely the first valve assembly 31, the second valve assembly 32 and the third valve assembly 33, and matching the different switch states of these three groups of valve assemblies, it is possible to open the air treatment channel while closing the exhaust channel, and open the exhaust channel while closing the air treatment channel. In other words, by switching the switch states of the above three groups of valve assemblies, the airflow direction inside the shell component 1 can be changed, thereby achieving different functions.

[0070] According to the fresh air component 100 of the embodiment of the present invention, by designing the inner cavity of the shell component 1 as described above and providing the first valve component 31, the second valve component 32, and the third valve component 33 having the above-mentioned functions, it is possible to achieve at least the switching of the internal circulation function, the fresh air function, and the exhaust function, thereby meeting the different needs of users. In addition, the first valve component 31, the second valve component 32, and the third valve component 33 are three groups of valve components that are independently controlled from each other, so that there is no mutual restriction or influence between the setting positions of these three groups of valve components. The setting position of each valve component can be selected separately according to the actual structural layout requirements, thereby improving the flexibility of the design and improving the adaptability to different models.

[0071] In some embodiments of the present invention, Figure 1 As shown, the outdoor fresh air inlet 104 is formed on the rear side of the lower part of the shell component 1, the indoor return air inlet 105 is formed on the left and right sides of the lower part of the shell component 1, and the indoor air outlet 106 is formed on the front side of the upper part of the shell component 1 and / or on the left and right sides of the upper part. Therefore, it can be ensured that the positions of the indoor air outlet and the indoor return air are far apart, avoiding the return air problem, and the air outlet area can be increased as much as possible to ensure the air outlet requirements, and the air inlet area can be increased as much as possible to ensure the air inlet requirements. Of course, the present invention is not limited to this. The number and setting position of the outdoor fresh air inlet 104, the indoor return air inlet 105 and the indoor air outlet 106 can also be specifically adjusted according to actual conditions, as long as the ventilation requirements of the above functions are met, which will not be elaborated here.

[0072] In some embodiments of the present invention, Figure 1As shown, the fresh air component 100 may further include an air treatment assembly 4, which is disposed within the exhaust chamber 103 and upstream of the indoor air outlet 106. In other words, the airflow entering the exhaust chamber 103 must first be processed by the air treatment assembly 4 before being discharged into the room through the indoor air outlet 106. This allows for both internal circulation and fresh air functions to be achieved, ensuring that the air entering the room meets user needs.

[0073] Furthermore, since the airflow during the exhaust function does not flow through the exhaust chamber 103 and is not processed by the air treatment assembly 4, the use of the air treatment assembly 4 when air treatment is not required can be avoided, thereby effectively reducing the utilization rate of the air treatment assembly 4 and extending the service life of the air treatment assembly 4. In addition, since the air treatment assembly 4 is arranged in the exhaust chamber 103, it can have a larger storage space, which is conducive to the installation of an air treatment assembly 4 with a larger volume, including a larger number or more types of air treatment units, thereby improving and enriching the air treatment effect, and facilitating the disassembly and assembly design of the air treatment assembly 4.

[0074] It should be noted that the specific composition of the air treatment component 4 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 is not limited here. In addition, it should be noted that the present invention is not limited to this. In other embodiments of the present invention, the air treatment component 4 may not be arranged in the exhaust chamber 103. For example, it may be arranged in the fan chamber 101 and / or the fresh air chamber 102, or it may be arranged outside the housing component 1, etc., which will not be repeated here.

[0075] In some embodiments of the present invention, the air treatment assembly 4 can be configured to be detachably mounted. For example, the housing assembly 1 can have a disassembly opening 113 (combined with a Figure 7 ), a disassembly opening 113 may be formed on the surface of the housing assembly 1. The disassembly opening 113 is used to insert and assemble the air treatment assembly 4. That is, the air treatment assembly 4 can be inserted into the exhaust chamber 103 through the disassembly opening 113, and can be pulled out of the exhaust chamber 103 through the disassembly opening 113, thereby facilitating the disassembly and assembly of the air treatment assembly 4, and facilitating cleaning, replacement, or maintenance of the air treatment assembly 4. Furthermore, a slide rail may be provided in the exhaust chamber 103, and the air treatment assembly 4 can be inserted into the slide rail through the disassembly opening 113, and can be removed from the disassembly opening 113 along the slide rail, thereby facilitating the disassembly and assembly of the air treatment assembly 4, and facilitating cleaning, replacement, or maintenance of the air treatment assembly 4.

[0076] In addition, in order to improve the installation stability and size of the air treatment component 4, the air treatment component 4 can be set to an oblique insertion structure. For example, the slide rail can be set to extend from front to back and from top to bottom. This not only increases the size of the air treatment component 4 in the exhaust chamber 103 and improves the air treatment effect, but also improves the installation stability of the air treatment component 4 and avoids the problem of the air treatment component 4 automatically falling out of the disassembly opening 113 from back to front. Of course, the present invention is not limited to this. The air treatment component 4 can also be set to be inserted horizontally, so that the size of the fresh air component 100 in the vertical direction can be reduced, thereby improving the structural compactness of the fresh air component 100.

[0077] In some embodiments of the present invention, Figure 1 As shown, the first valve assembly 31 is located downstream of the air treatment assembly 4 and upstream of the indoor air outlet 106. In other words, no matter how many control valves the first valve assembly 31 includes, each control valve is located downstream of the air treatment assembly 4 and upstream of the indoor air outlet 106 in the direction of air flow. As a result, there is sufficient space to install the first valve assembly 31, which is convenient for early installation and subsequent maintenance of the first valve assembly 31.

[0078] Furthermore, if Figure 1 As shown, the fan assembly 2 and the second valve assembly 32 are located below the air treatment assembly 4, the first valve assembly 31 is located above the air treatment assembly 4, and the indoor air outlet 106 is located above the first valve assembly 31. In other words, no matter how many control valves the first valve assembly 31 includes, each control valve is located above the air treatment assembly 4, and the indoor air outlet 106 is located above all the control valves in the first valve assembly 31. This provides ample space for installing the first valve assembly 31 and shortens the airflow path, making the housing assembly 1 compact and small.

[0079] In some embodiments of the present invention, Figure 1 As shown, the fan assembly 2 may include a centrifugal fan wheel 21, a third valve assembly 33 located at the rear side of the fan assembly 2, an air treatment assembly 4 located above the fan assembly 2, a first valve assembly 31 located above the air treatment assembly 4, and a second valve assembly 32 located below the air treatment assembly 4. Thus, the design of the housing assembly 1 meets the operating requirements of the centrifugal fan wheel 21, allowing the centrifugal fan wheel 21 to take in air from the rear side and discharge air from the top side. Thus, by utilizing the centrifugal fan wheel 21, the ventilation volume can be increased, meeting requirements such as a large fresh air volume.

[0080] In addition, when the relative positions of the third valve assembly 33, the second valve assembly 32 and the first valve assembly 31 are designed as above, Figure 1 and Figure 7As shown, the first valve assembly 31 may include a plurality of first baffles 313 arranged in a front-to-rear direction, each of which is pivotally connected to the housing assembly 1. For example, the pivot axis of each first baffle 313 extends in the left-right direction. The second valve assembly 32 may include a second baffle 322 pivotally connected to the housing assembly 1. For example, the pivot axis of the second baffle 322 extends in the left-right direction. The third valve assembly 33 may include a plurality of third baffles 333 arranged in a left-to-right direction, each of which is pivotally connected to the housing assembly 1. For example, the pivot axis of each third baffle 333 extends in the up-down direction. As a result, the third valve assembly 33, the second valve assembly 32, and the first valve assembly 31 have simple structures and occupy little space, making the housing assembly 1 compact and small.

[0081] Of course, the present invention is not limited thereto. In some specific embodiments of the present invention, Figure 1 As shown, the first valve assembly 31 may include a downstream control valve 310, and the downstream control valve 310 is arranged downstream of the air treatment assembly 4. That is to say, each control valve in the first valve assembly 31 does not need to be arranged downstream of the air treatment assembly 4. The first valve assembly 31 only needs to include the downstream control valve 310 arranged downstream of the air treatment assembly 4.

[0082] That is, in the direction of airflow, the downstream control valve 310 is located downstream of the air treatment assembly 4. Thus, when the downstream control valve 310 is in a closed state, even if the airflow discharged from the fan chamber 101 enters the exhaust chamber 103 and is processed by the air treatment assembly 4, it will be intercepted by the downstream control valve 310 and cannot flow to the indoor air outlet 106. This can prevent the airflow in the fan chamber 101 from being discharged into the room through the exhaust chamber 103 and the indoor air outlet 106.

[0083] Therefore, by setting the downstream control valve 310 downstream of the air treatment component 4, there is a larger space to set the downstream control valve 310 while ensuring that the downstream control valve 310 meets the above-mentioned functional requirements, so that multiple forms or a larger number of downstream control valves 310 can be selected to better realize the function of the first valve component 31, and it is beneficial to the early installation and later maintenance of the downstream control valve 310.

[0084] In some embodiments of the present invention, Figure 1As shown, when the first valve assembly 31 includes a downstream control valve 310, the downstream control valve 310 can also be simultaneously arranged upstream of the indoor air outlet 106. That is, in the direction of airflow, the downstream control valve 310 is located between the air treatment assembly 4 and the indoor air outlet 106. In this way, when the downstream control valve 310 is in a closed state, even if the airflow discharged from the fan chamber 101 enters the exhaust chamber 103 and is processed by the air treatment assembly 4, it will be intercepted by the downstream control valve 310 and cannot flow to the indoor air outlet 106. This can prevent the airflow in the fan chamber 101 from being discharged into the room from the indoor air outlet 106 through the exhaust chamber 103.

[0085] Therefore, by setting the downstream control valve 310 downstream of the air treatment component 4, there is a larger space to set the downstream control valve 310 under the premise of ensuring that the downstream control valve 310 meets the above-mentioned functional requirements, so that multiple forms or a larger number of downstream control valves 310 can be selected to better realize the function of the first valve component 31, and it is beneficial to the early installation and later maintenance of the downstream control valve 310.

[0086] It should be noted that when the downstream control valve 310 is located between the air treatment component 4 and the indoor air outlet 106, the first valve component 31 may also include a valve arranged at the indoor air outlet 106, or the indoor air outlet 106 may not be provided with a valve, being in an open state, or a ventilation grille may be provided.

[0087] Of course, the present invention is not limited to this. When the first valve assembly 31 includes a downstream control valve 310, the downstream control valve 310 may not be set upstream of the indoor air outlet 106. For example, in other embodiments of the present invention, when the downstream control valve 310 is set downstream of the air treatment assembly 4, the downstream control valve 310 may be set at the indoor air outlet 106, and so on.

[0088] In addition, the present invention is not limited thereto. In some other embodiments, when the first valve assembly 31 includes the downstream control valve 310, the first valve assembly 31 may also include an upstream control valve located upstream of the air treatment assembly 4. Alternatively, in some other embodiments, the first valve assembly 31 may be located as a whole upstream of the air treatment assembly 4, that is, in the direction of airflow, the first valve assembly 31 is located between the fan chamber 101 and the air treatment assembly 4. In this case, when the first valve assembly 31 is in a closed state, even if the airflow discharged from the fan chamber 101 enters the exhaust chamber 103, it will be intercepted by the first valve assembly 31 and will not be processed by the air treatment assembly 4, thereby effectively reducing the utilization rate of the air treatment assembly 4 and extending the service life of the air treatment assembly 4. In addition, it is ensured that the air entering the exhaust chamber 103 cannot flow to the indoor air outlet 106, thereby preventing the airflow in the fan chamber 101 from being discharged into the room from the indoor air outlet 106 through the exhaust chamber 103.

[0089] In some embodiments, as Figure 1 As shown, the fan chamber 101 can have two inlets, namely a first inlet 101a and a second inlet 101b. The fan chamber 101 can also have two outlets, namely a first outlet 101c and a second outlet 101d. The first inlet 101a is suitable for communicating with the indoor return air inlet 105, the second inlet 101b is suitable for communicating with the outlet of the fresh air chamber 102, the first outlet 101c is suitable for communicating with the inlet of the exhaust chamber 103, and the second outlet 101d is suitable for communicating with the inlet of the fresh air chamber 102. In this way, the air intake path from the indoor return air inlet 105 to the fan chamber 101, the air intake path from the fresh air chamber 102 to the fan chamber 101, the exhaust path from the fan chamber 101 to the exhaust chamber 103, and the exhaust path from the fan chamber 101 to the fresh air chamber 102 can be shortened, thereby reducing energy consumption.

[0090] In a specific example, the first inlet 101a and the indoor return air outlet 105 are the same opening, thereby further shortening the air intake path from the indoor return air outlet 105 to the fan chamber 101 and making the structure of the housing assembly 1 small and compact.

[0091] As in Figure 1 In the specific example shown, the third valve assembly 33 is provided at the second inlet 101b to control the on / off state of the second inlet 101b. When the second inlet 101b is open, the fan chamber 101 can inhale air from the fresh air chamber 102. Figure 1In the specific example shown, the second valve assembly 32 is disposed at the second outlet 101d to control the on / off state of the second outlet 101d. When the second outlet 101d is open, the fan chamber 101 can exhaust air into the fresh air chamber 102. Thus, the third valve assembly 33 and the second valve assembly 32 are simply positioned, and the control is effective and reliable.

[0092] As in Figure 1 In the specific example shown, the fan chamber 101 includes a front chamber 1011, a rear chamber 1012 and an upper chamber 1013. The rear chamber 1012 is located in front of the fresh air chamber 102, the front chamber 1011 is located in front of the rear chamber 1012, the fan assembly 2 is arranged in the front chamber 1011, and the upper chamber 1013 is located above the front chamber 1011 and the rear chamber 1012. The upper chamber 1013 is connected to the top of the front chamber 1011, the top of the upper chamber 1013 is configured as a first outlet 101c, and the rear of the upper chamber 1013 is configured as a second outlet 101d.

[0093] As a result, the air intake path from the indoor return air port 105 to the fan chamber 101, the air intake path from the fresh air chamber 102 to the fan chamber 101, the exhaust path from the fan chamber 101 to the exhaust chamber 103, and the exhaust path from the fan chamber 101 to the fresh air chamber 102 can be shortened, thereby reducing energy consumption. Furthermore, the structure of the housing assembly 1 is made small and compact.

[0094] In some embodiments of the present invention, a fourth valve assembly 34 (combined with Figure 8 ), the fourth valve assembly 34 is in the open state so that the fan chamber 101 can inhale air from the room through the indoor return air port 105. Specifically, the fourth valve assembly 34 can be switched between the open state and the closed state. Figure 2 and Figure 3 As shown, when the fourth valve assembly 34 is in an open state, the fan chamber 101 is connected to the indoor return air outlet 105, and the indoor return air outlet 105 is connected to the room. The fan chamber 101 can inhale air from the room through the indoor return air outlet 105. That is, if the fan assembly 2 is working at this time, the indoor air will flow into the fan chamber 101 through the indoor return air outlet 105.

[0095] It should be noted that "a fourth valve assembly 34 is provided corresponding to the indoor return air inlet 105" does not require that the fourth valve assembly 34 be provided at the indoor return air inlet 105. It is sufficient that the fourth valve assembly 34 is located in an airflow path connected to the indoor return air inlet 105 and that the fourth valve assembly 34, when open, enables the fan chamber 101 to draw air from the room through the indoor return air inlet 105. Of course, the fourth valve assembly 34 can also be provided at the indoor return air inlet 105 for easier installation.

[0096] like Figure 1 As shown, when the fourth valve assembly 34 is in a closed state, the fan chamber 101 and the indoor return air outlet 105 are in a blocked state, and / or the indoor return air outlet 105 and the indoor room are in a blocked state, the fan chamber 101 cannot draw air from the indoor room through the indoor return air outlet 105, that is, if the fan assembly 2 is working at this time, the indoor air cannot flow into the indoor return air outlet 105, or the air flowing into the indoor return air outlet 105 cannot flow into the fan chamber 101, or the indoor air cannot flow into the indoor return air outlet 105, and the air flowing into the indoor return air outlet 105 cannot flow into the fan chamber 101.

[0097] In this way, Figure 1 As shown, the fourth valve assembly 34 can be switched to a closed state in the fresh air function, and only the outdoor air provides air to the fan chamber 101, thereby ensuring sufficient fresh air intake. Figure 2 and Figure 3 As shown, under the internal circulation function and the exhaust function, the fourth valve assembly 34 is switched to an open state, thereby meeting the requirement of supplying air from the room to the fan chamber 101.

[0098] It should be noted that the structure and location of the fourth valve assembly 34 are not limited as long as the above requirements are met. For example, it can be in the form of an electric switch door, an electric air guide plate, a manual switch door, etc., and can be located at the indoor return air outlet 105 or outside the indoor return air outlet 105, such as on the housing component 300 of the air conditioner 1000 described later (in combination with Figure 8 ), or between the indoor return air outlet 105 and the fan chamber 101 in the air flow direction, etc., which will not be described here.

[0099] Of course, the present invention is not limited to this. In other embodiments of the present invention, the fresh air component 100 may not have the fourth valve assembly 34. At this time, the fan chamber 101 and the indoor return air outlet 105 are always connected, and the indoor return air outlet 105 and the indoor room are always connected. As long as the fan assembly 2 is working, the indoor air will flow into the fan chamber 101 through the indoor return air outlet 105. For example, under the above-mentioned fresh air function, internal circulation function and exhaust function, the indoor air can enter the fan chamber 101.

[0100] For example, in the fresh air function, indoor air and outdoor fresh air enter the fan chamber 101 simultaneously, are then processed by the air treatment assembly 4, and are discharged indoors, thereby achieving a certain internal circulation effect while realizing the fresh air function. In addition, when the fresh air component 100 does not have the fourth valve assembly 34, a ventilation grille can be installed at the indoor return air outlet 105 to achieve a safety effect.

[0101] In some embodiments of the present invention, Figure 1As shown, the fan assembly 2 and the second valve assembly 32 are arranged below the air treatment assembly 4, and the downstream control valve 310 is arranged above the air treatment assembly 4. Therefore, by arranging the second valve assembly 32 and the downstream control valve 310 on the upper and lower sides of the air treatment assembly 4, respectively, the mutual influence and interference between the second valve assembly 32 and the downstream control valve 310 can be effectively avoided, so that the second valve assembly 32 and the downstream control valve 310 have relatively sufficient installation space. In addition, by arranging the fan assembly 2 and the second valve assembly 32 together below the air treatment assembly 4, it is beneficial for the second valve assembly 32 to control whether the fan chamber 101 exhausts air to the fresh air chamber 102, thereby shortening the exhaust path from the fan chamber 101 to the fresh air chamber 102 and reducing energy consumption.

[0102] In some embodiments of the present invention, Figure 1 As shown, when the downstream control valve 310 is disposed above the air treatment assembly 4, the indoor air outlet 106 can be disposed above the downstream control valve 310. Therefore, by disposing both the indoor air outlet 106 and the downstream control valve 310 above the air treatment assembly 4, the downstream control valve 310 is able to control whether the exhaust chamber exhausts air to the indoor air outlet 106, thereby shortening the exhaust path from the exhaust chamber 103 to the indoor air outlet 106 and reducing energy consumption. Furthermore, since the indoor air outlet 106 is disposed at a higher height than the downstream control valve 310, the indoor air supply height can be increased, thereby adjusting the indoor air environment over a wider range.

[0103] In some embodiments of the present invention, Figure 1 As shown, the fan assembly 2 may include a centrifugal fan wheel 21, a third valve assembly 33 disposed at the rear side of the fan assembly 2, an air treatment assembly 4 disposed above the fan assembly 2, a first valve assembly 31 disposed above the air treatment assembly 4, and a second valve assembly 32 disposed below the air treatment assembly 4. Therefore, the design of the fan chamber 101 meets the operating requirements of the centrifugal fan wheel 21, allowing the centrifugal fan wheel 21 to take in air from the rear side and discharge air from the top side. Thus, by utilizing the centrifugal fan wheel 21, the ventilation volume can be increased, meeting requirements such as a large fresh air volume.

[0104] Furthermore, by arranging the third valve assembly 33 at the rear side of the fan assembly 2 and the first valve assembly 31 above the fan assembly 2, the space can be fully utilized, ensuring that both the third valve assembly 33 and the first valve assembly 31 have ample space for installation, thereby avoiding interference between the two. Furthermore, by arranging the second valve assembly 32 below the air treatment assembly 4 and the first valve assembly 31 above the air treatment assembly 4, the space can be fully utilized, ensuring that both the second valve assembly 32 and the first valve assembly 31 have ample space for installation, thereby avoiding interference between the two.

[0105] It should be noted that the directional nouns described herein, such as up, down, left, right, front, and back, are for the purpose of simplifying and clarifying the description and are based on the accompanying drawings, and should not be understood as limiting the present application. Figure 8 When the fresh air component 100 is used in a vertical air conditioner 1000, the side of the vertical air conditioner 1000 facing the user is the front, and the side facing away from the user is the rear.

[0106] In some embodiments of the present invention, the first valve assembly 31 and / or the third valve assembly 33 may include a driver, a connecting rod, and multiple baffles. The multiple baffles are arranged in sequence along the length of the connecting rod, and each baffle is connected to the connecting rod. The driver is used to drive the baffles to rotate. Therefore, the valve assembly has a simple structure and facilitates opening and closing control. For example, in one specific example, the driver can drive one of the baffles to rotate, and this baffle then drives the remaining baffles to rotate via the connecting rod. For example, in another specific example, the driver can drive the connecting rod to move along a predetermined trajectory, and during the movement of the connecting rod, the multiple baffles are driven to rotate.

[0107] For example, in some embodiments of the present invention, Figure 1 and Figure 7 As shown, the first valve assembly 31 may include a first driver 311, a first connecting rod 312, and a plurality of first baffles 313. The plurality of first baffles 313 are arranged in sequence along the length of the first connecting rod 312, and each first baffle 313 is connected to the first connecting rod 312. The first driver 311 drives one of the first baffles 313 to rotate, and the first baffle 313 drives the remaining first baffles 313 to rotate via the first connecting rod 312. Therefore, the structure of the first valve assembly 31 is simple, and it is convenient to control the switching of the first valve assembly 311 between the open state and the closed state.

[0108] For example, in a specific example of the present invention, when the first valve assembly 31 is in a closed state, multiple first baffles 313 are generally located on the same plane, and two adjacent first baffles 313 are connected, overlapped, or have only a small airflow gap. When the first valve assembly 31 is in an open state, multiple first baffles 313 are parallel to each other, and the plane where each first baffle 313 is located is generally perpendicular to the extension direction of the first connecting rod 312. Therefore, it can ensure that the distance between two adjacent first baffles 313 is large, thereby improving the airflow pass rate, reducing wind resistance, and reducing energy consumption.

[0109] For example, in some embodiments of the present invention, Figure 1 and Figure 7As shown, the third valve assembly 33 may include a third driver, a third connecting rod 332, and a plurality of third baffles 333. The plurality of third baffles 333 are arranged in sequence along the length of the third connecting rod 332, and each third baffle 333 is connected to the third connecting rod 332. The third driver drives one of the third baffles 333 to rotate, and the third baffle 333 drives the remaining third baffles 333 to rotate via the third connecting rod 332. Therefore, the structure of the third valve assembly 33 is simple, and it is convenient to control the switching of the third valve assembly 333 between the open state and the closed state.

[0110] For example, in a specific example of the present invention, when the third valve assembly 33 is in a closed state, the multiple third baffles 333 are generally located on the same plane, and two adjacent third baffles 333 are connected, overlapped, or have only a small airflow gap. When the third valve assembly 33 is in an open state, the multiple third baffles 333 are parallel to each other, and the plane where each third baffle 333 is located is generally perpendicular to the extension direction of the third connecting rod 332. Therefore, it can ensure that the distance between two adjacent third baffles 333 is large, thereby improving the airflow pass rate, reducing wind resistance, and reducing energy consumption.

[0111] For example, in some embodiments of the present invention, Figure 1 and Figure 8 As shown, the second valve assembly 32 may include a second driver 321 and a second baffle 322, and the second driver 321 drives the second baffle 322 to rotate. Therefore, the structure of the second valve assembly 32 is simple, and it is easy to control the second valve assembly 32 to switch between the open state and the closed state.

[0112] In some embodiments of the present invention, Figure 1 and Figure 7 As shown, the housing assembly 1 may include a first housing 121, to which the second valve assembly 32 may be mounted, and the third valve assembly 33 may also be mounted simultaneously. Therefore, mounting the second valve assembly 32 and the third valve assembly 33 on the same housing, namely, the first housing 121, simplifies assembly and facilitates driver wiring. For example, the second driver 321 and the third driver may both be mounted on the first housing 121, which facilitates wiring of the second driver 321 and the third driver, improving wiring neatness and safety. In some examples, the first housing 121 may be an integrally molded part, further improving processing and assembly efficiency.

[0113] In some embodiments of the present invention, Figure 1 and Figure 7As shown, the shell assembly 1 can also include a second shell 122, which is located on the rear side of the first shell 121, and the second shell 122 is assembled and connected to the first shell 121. The second shell 122 and the first shell 121 jointly define the fresh air chamber 102, and the first shell 121 has a first open opening 107 (i.e., the second outlet 101d) and a second open opening 108 (i.e., the second inlet 101b), and the first open opening 107 is located above the second open opening 108.

[0114] The upper part of the fresh air chamber 102 is connected to the first open port 107, and the second valve assembly 32 is used to control the switch of the first open port 107. When the first open port 107 is opened, the fresh air chamber 102 and the first open port 107 are connected. The front side of the fresh air chamber 102 is connected to the second open port 108. The third valve assembly 33 is used to control the switch of the second open port 108. When the second open port 108 is opened, the fresh air chamber 102 and the second open port 108 are connected.

[0115] Therefore, by arranging the first open port 107 and the second open port 108 in an upper and lower arrangement on the first shell 121, it can be ensured that the installation and operation of the second valve assembly 32 and the third valve assembly 33 do not affect or interfere with each other, thereby simplifying the structure of the first shell 121, and the structure of the first shell 121 according to the embodiment of the present invention is simple, compact and small.

[0116] In some specific examples of the present invention, when the second valve assembly 32 includes a second driver 321 and a second baffle 322, for example, the pivot axis of the second baffle 322 extends in the left-right direction, and the upper end of the second baffle 322 is pivotally connected to the first housing 121. In some specific examples of the present invention, when the third valve assembly 33 includes a third driver, a third connecting rod 332, and a third baffle 333, a plurality of third baffles 333 are sequentially arranged in the left-right direction, the third connecting rod 332 extends in the left-right direction, and each third baffle 333 is pivotally connected to the housing assembly 1. For example, the pivot axis of each third baffle 333 extends in the up-down direction. The third driver is used to drive the plurality of third baffles 333 to rotate. When the third valve assembly 33 is in the closed state, the plurality of third baffles 333 collectively block the second open port 108. When the third valve assembly 33 is in the open state, the plurality of third baffles 333 collectively open the second open port 108.

[0117] In some embodiments of the present invention, Figure 1As shown, the fan chamber 101 may include three chambers, namely a front chamber 1011, a rear chamber 1012 located at the rear side of the front chamber 1011, and an upper chamber 1013 located above the front chamber 1011 and the rear chamber 1012. The upper first outlet of the upper chamber 1013 is 101c, which is connected to the exhaust chamber 103, and the fan assembly 2 is arranged in the front chamber 1011.

[0118] Combine Figure 7 The shell assembly 1 also includes a third shell 123 and a fourth shell 124. The third shell 123 is located on the front side of the first shell 121, and the third shell 123 is assembled and connected to the first shell 121. The third shell 123 and the first shell 121 jointly define a rear chamber 1012. The fourth shell 124 is located on the front side of the third shell 123, and the fourth shell 124 is assembled and connected to the third shell 123. The fourth shell 124 and the third shell 123 jointly define a front chamber 1011, so that the fourth shell 124 and the third shell 123 can be used as the volute of the fan assembly 2.

[0119] like Figure 1 and Figure 7 As shown, a third opening 109 is provided between the fourth shell 124 and the third shell 123, located above the front chamber 1011. The third opening 109 can be formed on at least one of the fourth shell 124 and the third shell 123. An upper chamber 1013 is defined between the first shell 121, the third shell 123, and the fourth shell 124. The upper chamber 1013 can be defined by the first shell 121 and the third shell 123, or by the first shell 121, the fourth shell 124, and the third shell 123.

[0120] like Figure 1 As shown, the front lower side of the upper chamber 1013 can be communicated with the third open port 109, so that when the third open port 109 is in an open state, the upper chamber 1013 is in communication with the front chamber 1011. The rear portion of the upper chamber 1013 can be communicated with the first open port 107, so that when the first open port 107 is in an open state, the upper chamber 1013 is in communication with the fresh air chamber 102. In this way, when the second valve assembly 32 opens the first open port 107, the air in the fan chamber 101 can flow into the fresh air chamber 102 through the front chamber 1011, the upper chamber 1013, and the first open port 107, thereby achieving exhaust from the fan chamber 101 to the fresh air chamber 102 when the second valve assembly 32 is in an open state.

[0121] In addition, in some cases, the air in the fan chamber 101 can flow into the exhaust chamber 103 through the front chamber 1011 and the upper chamber 1013, so that the fan chamber 101 can be exhausted into the exhaust chamber 103. Therefore, the housing assembly 1 has a simple, compact, and small structure, a short and simple gas flow path, and can effectively achieve the switching of the above-mentioned multiple functions.

[0122] In some embodiments of the present invention, Figure 7 As shown, indoor return air vents 105 are formed on the left and right sides of the first housing 121, respectively. The indoor return air vents 105 can be formed on at least one of the first housing 121 and the second housing 122. The indoor return air vents 105 are located in front of the fresh air chamber 102 and can be connected to the rear chamber 1012. Therefore, by arranging the indoor return air vents 105 and the position of the third valve assembly 33 as described above, it can be ensured that when the third valve assembly 33 closes the second opening 108, it can not affect the indoor return air vents 105 from providing airflow to the rear chamber 1012 of the fan chamber 101. This makes the structure of the housing assembly 1 simple, easy to design and process, and can effectively meet the switching requirements of the above-mentioned multiple functions.

[0123] In some embodiments of the present invention, Figure 1 and Figure 7 As shown, the housing assembly 1 may include an upper housing assembly 11 and a lower housing assembly 12. The upper housing assembly 11 is located above the lower housing assembly 12 and is assembled and connected to the lower housing assembly 12. The upper housing assembly 11 has an exhaust chamber 103, and the lower housing assembly 12 has a blower chamber 101 and a fresh air chamber 102. Therefore, the housing assembly 1 has a simple structure, is easy to process and assemble, and can simply and effectively define the blower chamber 101, the exhaust chamber 103, and the fresh air chamber 102, and achieve sealing of non-open areas.

[0124] In some embodiments, as Figure 1 and Figure 7 As shown, an outdoor fresh air inlet 104 is provided on the rear side of the lower shell assembly 12, and an indoor return air inlet 105 is provided on the left and right sides of the lower shell assembly 12 respectively, and the indoor air outlet 106 is provided on the front upper part of the upper shell assembly 11, and / or on the left and right sides of the upper shell assembly 11. That is to say, the indoor air outlet 106 can all be provided on the front upper part of the upper shell assembly 11, or all be provided on the left and right sides of the upper shell assembly 11, or part can be provided on the front upper part of the upper shell assembly 11, and the rest can be provided on the left and right sides of the upper shell assembly 11.

[0125] Therefore, it is possible to ensure that the indoor air outlet and the indoor return air are far apart, avoiding return air problems, and the air outlet area can be maximized to meet the air outlet requirements, and the air inlet area can be maximized to meet the air inlet requirements. Of course, the present invention is not limited to this. The number and location of the outdoor fresh air inlet 104, the indoor return air inlet 105, and the indoor air outlet 106 can also be adjusted according to actual conditions, as long as the ventilation requirements of the above functions are met. This will not be elaborated here.

[0126] In some embodiments, as Figure 1 and Figure 7 As shown, the lower housing assembly 12 can be assembled from several sub-housings to facilitate assembly. For example, in some specific examples, the lower housing assembly 12 can be composed of the first housing 121, the second housing 122, the third housing 123, and the fourth housing 124. The specific structural scheme can be described above and will not be repeated here.

[0127] In some embodiments, as Figure 1 and Figure 7 As shown, the upper housing assembly 11 can be assembled from several sub-housings to facilitate assembly. For example, in some specific examples, the upper housing assembly 11 can include a fifth housing 111 and a sixth housing 112. The fifth housing 111 is located in front of the sixth housing 112, and the fifth housing 111 and the sixth housing 112 are assembled and connected. The fifth housing 111 and the sixth housing 112 together define the exhaust chamber 103. The front surface of the fifth housing 111 is formed with a disassembly port 113, which is suitable for inserting the air treatment assembly 4 described above. The first valve assembly 31 is mounted on the sixth housing 112.

[0128] Therefore, the upper housing assembly 11 has a simple structure and is easy to assemble, and also facilitates the assembly of the first valve assembly 31 and the air treatment assembly 4. Furthermore, slide rails can be provided in the fifth housing 111 and the sixth housing 112, and the air treatment assembly 4 can be inserted into the slide rails through the disassembly opening 113 and removed from the disassembly opening 113 along the slide rails, thereby facilitating the assembly and disassembly of the air treatment assembly 4 and facilitating cleaning, replacement, or maintenance of the air treatment assembly 4.

[0129] In some specific examples of the present invention, when the first valve assembly 31 includes a first driver 311, a first connecting rod 312 and a first baffle 313, multiple first baffles 313 are arranged in sequence along the front-to-back direction, the first connecting rod 312 extends along the front-to-back direction, and each first baffle 313 is pivotally connected to the shell assembly 1. For example, the pivot axis of each first baffle 313 extends along the left-right direction, and the first driver 311 is used to drive the multiple first baffles 313 to rotate. When the first valve assembly 31 is in the closed state, the multiple first baffles 313 jointly block the cross-section at the corresponding position of the exhaust chamber 103. When the first valve assembly 31 is in the open state, the multiple third baffles 333 jointly open the cross-section at the corresponding position of the exhaust chamber 103.

[0130] In addition, in some embodiments of the present invention, the first shell 121 can be an integrally molded part, the second shell 122 can be an integrally molded part, the third shell 123 can be an integrally molded part, the fourth shell 124 can be an integrally molded part, the fifth shell 111 can be an integrally molded part, and the sixth shell 112 can be an integrally molded part, thereby facilitating processing and assembly and improving the structural reliability of the shell assembly 1.

[0131] In some embodiments, the indoor air outlet 106 can be located at the upper front portion of the fifth housing 111; the indoor air outlet 106 can also be located on the left and right sides of the sixth housing 112; or the indoor air outlet 106 can be partially located at the upper front portion of the fifth housing 111, with the remaining portion located on the left and right sides of the sixth housing 112. Thus, the air outlet range can be expanded, allowing for multi-directional adjustment of indoor air.

[0132] In some embodiments of the present invention, Figure 1 As shown, the fresh air component 100 may include: a fresh air duct 5 and a fifth valve assembly 35. The fresh air duct 5 is assembled at the outdoor fresh air inlet 104 of the housing assembly 1, thereby connecting the fresh air duct 5 to the outdoor fresh air inlet 104. When the fifth valve assembly 35 is in an open state, the fresh air chamber 102 can communicate with the outside through the fresh air duct 5 and the outdoor fresh air inlet 104. Specifically, the fifth valve assembly 35 is switchable between an open state and a closed state.

[0133] like Figure 1 As shown, when the fifth valve assembly 35 is in the open state, the fresh air chamber 102 can introduce outdoor air from the outside through the fresh air duct 5. That is, if the fan assembly 2 is working at this time, the outdoor air will flow into the fresh air duct 5, and then enter the fresh air chamber 102 through the outdoor fresh air outlet 104.

[0134] like Figure 2As shown, when the fifth valve assembly 35 is in a closed state, the fresh air chamber 102 cannot introduce outdoor air from the outside through the fresh air duct 5, that is, if the fan assembly 2 is working at this time, the outdoor air cannot flow into the fresh air duct 5, or, although the outdoor air can flow into the fresh air duct 5, the air in the fresh air duct 5 cannot enter the fresh air chamber 102 through the outdoor fresh air inlet 104, or, the outdoor air cannot flow into the fresh air duct 5, and the air in the fresh air duct 5 cannot enter the fresh air chamber 102 through the outdoor fresh air inlet 104.

[0135] like Figure 3 As shown, when the fifth valve assembly 35 is in the open state, the air in the fresh air chamber 102 can be discharged to the outside through the fresh air duct 5. That is, if the fan assembly 2 is working at this time, the air in the fresh air chamber 102 will be discharged to the fresh air duct 5 through the outdoor fresh air outlet 104, and then discharged to the outside through the fresh air duct 5.

[0136] Therefore, by providing the fifth valve assembly 35 , the overall airtightness of the fresh air component 100 can be improved without using the fresh air duct 5 for air intake or exhaust.

[0137] It should be noted that the fresh air duct 5 can be connected to the outside through a fresh air hose, thereby improving the convenience and reliability of the fresh air duct 5 connecting to the outside. In addition, it should be noted that the number of fresh air ducts 5 is not limited and can be one or more. When multiple fresh air ducts 5 are provided, multiple fresh air ducts 5 can be used simultaneously, or only one can be used, with the others reserved for backup.

[0138] In some embodiments of the present invention, the fifth valve assembly 35 can be installed on the fresh air duct 5, so as to facilitate the installation of the fifth valve assembly 35, and the fifth valve assembly 35 can open the fresh air duct 5 to enable the fresh air chamber 102 to be connected to the outside through the fresh air duct 5. The fifth valve assembly 35 can also close the fresh air duct 5 to block the fresh air chamber 102 from the outside through the fresh air duct 5, thereby simply and effectively realizing the above functions.

[0139] For example, in some embodiments of the present invention, the fifth valve assembly 35 may include a fifth driver and a fifth baffle, and the fifth driver drives the fifth baffle to rotate. Therefore, the structure of the fifth valve assembly 35 is simple, and it is convenient to control the fifth valve assembly 35 to switch between the open state and the closed state.

[0140] It should be noted that the first valve assembly 31, the second valve assembly 32, the third valve assembly 33, the fourth valve assembly 34, and the fifth valve assembly 35 are not limited to having only two states: open and closed.

[0145] Moreover, when the fan assembly 2 is configured to include a centrifugal wind wheel 21, a large amount of fresh air can be achieved, and when the fresh air component 100 includes a purification device, a large amount of purification can be achieved. In addition, it can be understood that in addition to the centrifugal wind wheel 21, the fan assembly 2 can also include a drive motor 22 for driving the centrifugal wind wheel 21 to rotate, etc., which will not be described here. It should be noted that the composition of the fan assembly 2 is not limited to this, for example, it can also include a cross-flow fan, an axial flow fan, a diagonal flow fan, etc. In addition, the air heat exchange component 200 may include a heat exchanger and / or electric auxiliary heating, etc.
