[0065] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0066] like Figures 1 to 18As shown, a first embodiment of the present invention provides a ventilation component, which includes a main body 10, a ventilation channel 20, and a fan blade 30. The main body 10 includes a first chamber 101 and a second chamber 102 that are interconnected. The main body 10 also includes a first air inlet 011, a first air outlet 012, a second air inlet 021, and a second air outlet 022. The first air inlet 011 and the second air inlet 021 are both connected to the first chamber 101; the first air outlet 012 and the second air outlet 022 are both connected to the second chamber 102, and the first air outlet 012 and the second air inlet 021 are respectively connected to the indoor environment. The ventilation channel 20 is respectively connected to the first chamber 101 and the second chamber 102. The ventilation channel 20 has a first opening 201 and a second opening 202 that are arranged opposite to each other. The first opening 201 is used to communicate with the outdoor environment, and the second opening 202 is used to communicate with the indoor environment. The fan blade 30 is arranged in the second chamber 102. The ventilation component has a fresh air mode, an exhaust mode, and a circulation mode. When the ventilation component is in the fresh air mode, the first opening 201, the first air inlet 011, and the first air outlet 012 are in an open state, and the second opening 202, the second air inlet 021, and the second air outlet 022 are in a closed state. When the ventilation component is in the exhaust mode, the second air inlet 021, the second air outlet 022, and the first opening 201 are in an open state, and the first air inlet 011, the first air outlet 012, and the second opening 202 are in a closed state. When the ventilation component is in the circulation mode, the second opening 202, the first air inlet 011, and the first air outlet 012 are in an open state, and the first opening 201, the second air inlet 021, and the second air outlet 022 are in a closed state. Figures 3 to 5 The direction of the arrow is the direction of air flow.

[0067] By applying the technical solution of the present invention, the main body 10 and the ventilation channel 20 cooperate to enable the same ventilation component to achieve the effect of integrating a fresh air intake device, a dirty air exhaust device, and an indoor air circulation device, thereby reducing the space occupied by the device and saving the device cost. Specifically, the main body 10 is provided with a first chamber 101 and a second chamber 102 that are interconnected, and the main body 10 is also provided with a first air inlet 011 and a second air inlet 021 that are respectively connected to the first chamber 101, and the main body 10 is also provided with a first air outlet 012 and a second air outlet 022 that are respectively connected to the second chamber 102, and the first air outlet 012 and the second air inlet 021 are respectively used to communicate with the indoor environment; the ventilation channel 20 is respectively connected to the first chamber 101 and the second chamber 102, and the ventilation channel 20 has a first opening 201 and a second opening 202, the first opening 201 is used to communicate with the outdoor environment, and the second opening 202 is used to communicate with the indoor environment.

[0068] When the ventilation component is required to realize the fresh air mode, the first opening 201, the first air inlet 011 and the first air outlet 012 are kept in the open state, while the second opening 202, the second air inlet 021 and the second air outlet 022 are kept in the closed state. At this time, under the action of the fan blades 30, the outdoor fresh air passes through the first opening 201, the ventilation channel 20, the first air inlet 011, the first chamber 101 and the second chamber 102 in sequence, and then flows into the room through the first air outlet 012;

[0069] When the ventilation component is required to realize exhaust mode, the second air inlet 021, the second air outlet 022 and the first opening 201 are kept in an open state, while the second opening 202, the first air inlet 011 and the first air outlet 012 are kept in a closed state. At this time, under the action of the fan blades 30, the indoor air passes through the second air inlet 021, the first chamber 101, the second chamber 102, the second air outlet 022 and the ventilation channel 20 in sequence, and then flows to the outside through the first opening 201;

[0070] When the ventilation component is required to realize the circulation mode, the second opening 202, the first air inlet 011 and the first air outlet 012 are kept in the open state, and the first opening 201, the second air inlet 021 and the second air outlet 022 are kept in the closed state. At this time, under the action of the fan blade 30, the indoor air passes through the second opening 202, the ventilation channel 20, the first air inlet 011, the first chamber 101 and the second chamber 102 in turn, and then flows into the room through the first air outlet 012, thereby realizing the circulation of the indoor air.

[0071] Traditional solutions typically require independent fresh air intake, dirty air exhaust, and indoor air circulation devices to achieve fresh air mode, exhaust mode, and circulation mode, respectively. These three separate components take up a lot of space and are costly. Compared to traditional solutions, this solution enables the same ventilation component to achieve three circulation modes by controlling the different air inlets, outlets, and openings on the same ventilation component, reducing both the space occupied by the component and its cost.

[0072] like Figures 2 to 10As shown, specifically, the ventilation component also includes a blocking component, which is arranged on the main body 10, and the blocking component includes a first blocking portion 41 and a second blocking portion 42, and the first blocking portion 41 and the second blocking portion 42 can be movably arranged relative to the main body 10; the first blocking portion 41 has a first working position and a second working position that are relatively set, when the first blocking portion 41 is in the first working position, the first air inlet 011 is in a blocked state, and the second air outlet 022 is in an open state; when the first blocking portion 41 is in the second working position, the first air inlet 011 is in an open state, and the second air outlet 022 is in a blocked state; the second blocking portion 42 has a third working position and a fourth working position that are relatively set, when the second blocking portion 42 is in the third working position, the first air outlet 012 is in a blocked state, and the second air inlet 021 is in an open state; when the second blocking portion 42 is in the fourth working position, the first air outlet 012 is in an open state, and the second air inlet 021 is in a blocked state. The first blocking portion 41 controls the state of the first air inlet 011 and the second air outlet 022, while the second blocking portion 42 controls the state of the second air inlet 021 and the first air outlet 012. The above arrangement can minimize the number of components in the blocking assembly, reducing the cost of the blocking assembly and the cost of ventilation components.

[0073] like Figures 3 to 5 As shown, in this solution, the first chamber 101 and the second chamber 102 are arranged side by side, that is, the first chamber 101 and the second chamber 102 are arranged coaxially.

[0074] This solution does not limit the specific positions of the first air inlet 011 and the second air inlet 021 on the first chamber 101, wherein the first air inlet 011 and the second air inlet 021 can be set on the side wall of the first chamber 101 away from the second chamber 102, or on the circumferential side wall of the first chamber 101.

[0075] This solution does not limit the specific locations of the first air outlet 012 and the second air outlet 022 on the second chamber 102. The first air outlet 012 and the second air outlet 022 can be located on the sidewall of the second chamber 102 away from the first chamber 101, or on the circumferential sidewall of the second chamber 102.

[0076] In this embodiment, the first air inlet 011 and the second air inlet 021 are arranged on the circumferential side wall of the first chamber 101 at intervals along the circumference of the first chamber 101. The first air outlet 012 and the second air outlet 022 are arranged on the circumferential side wall of the second chamber 102 at intervals along the circumference of the second chamber 102. The first air inlet 011 and the second air outlet 022 are distributed along the direction from the first chamber 101 to the second chamber 102. This arrangement makes the distance between the first air inlet 011 and the second air outlet 022 as close as possible, facilitating the switching of the first blocking portion 41 between the first working position and the second working position. The second air inlet 021 and the first air outlet 012 are distributed along the direction from the first chamber 101 to the second chamber 102. This arrangement makes the distance between the second air inlet 021 and the first air outlet 012 as close as possible, facilitating the switching of the second blocking portion 42 between the third working position and the fourth working position. Furthermore, the above arrangement facilitates the installation of the ventilation component, that is, ensures that the first air outlet 012 and the second air inlet 021 are all facing the indoor side.

[0077] The first blocking portion 41 and the second blocking portion 42 may be driven respectively by providing two driving mechanisms.

[0078] like Figures 3 to 10 As shown, in this embodiment, the ventilation component further includes a first driving member 50, which is disposed on the main body 10 and is drivably connected to the first blocking portion 41 and the second blocking portion 42, respectively. The first driving member 50 drives the first blocking portion 41 and the second blocking portion 42 to move synchronously, so that when the first blocking portion 41 is in the first working position, the second blocking portion 42 is in the third working position, and when the first blocking portion 41 is in the second working position, the second blocking portion 42 is in the fourth working position. In this embodiment, the first driving member 50 is used to synchronously drive the first blocking portion 41 and the second blocking portion 42. This configuration can minimize the number of components in the ventilation component and enable the first air inlet 011, the first air outlet 012, the second air inlet 021, and the second air outlet 022 to switch states synchronously, thereby improving the smoothness of the ventilation component when switching modes.

[0079] Furthermore, the ventilation component also includes a connecting portion 60, which is swingably disposed on the main body 10. The first blocking portion 41 is disposed at the first end of the connecting portion 60, and the second blocking portion 42 is disposed at the second end of the connecting portion 60. The first driving member 50 is drivingly connected to the connecting portion 60 so that the first end of the connecting portion 60 drives the first blocking portion 41 to switch between the first working position and the second working position, and the second end of the connecting portion 60 drives the second blocking portion 42 to switch between the third working position and the fourth working position. In this embodiment, the first air inlet 011 and the second air inlet 021 are relatively distributed along the radial direction of the first chamber 101. The connecting portion 60 is a rod-shaped structure, and is hingedly disposed with the main body 10 at the middle position in the longitudinal direction of the connecting portion 60, that is, the first end of the connecting portion 60 drives the first blocking portion 41 to perform circular motion, and the second end of the connecting portion 60 drives the second blocking portion 42 to perform circular motion. Specifically, the first driving member 50 is a first driving motor.

[0080] like Figure 11 As shown, specifically, the first blocking portion 41 and the second blocking portion 42 are detachably connected to the connecting portion 60 via latches. This arrangement facilitates assembly of the first blocking portion 41 and the second blocking portion 42 with the connecting portion 60.

[0081] In some other embodiments of the present scheme, the first blocking part 41 and the second blocking part 42 can be set to a flip structure. At this time, the flip axis of the first blocking part 41 is located between the first air outlet 012 and the second air inlet 021, and the extension direction of the flip axis of the first blocking part 41 is perpendicular to the distribution direction from the first air outlet 012 to the second air inlet 021. The flip axis of the second blocking part 42 is located between the first air inlet 011 and the second air outlet 022, and the extension direction of the flip axis of the second blocking part 42 is perpendicular to the distribution direction from the first air inlet 011 to the second air outlet 022; that is, at this time, the flip axis of the first blocking part 41 is arranged parallel to the flip axis of the second blocking part 42, and the first driving member 50 can be driven and connected to the flip axis of the first blocking part 41 and the flip axis of the second blocking part 42 respectively, so that the first blocking part 41 and the second blocking part 42 can be flipped synchronously.

[0082] When the first and second sealing portions 41, 42 are in a reversible structure, the ventilation component may further include a transmission structure, and the first driving member 50 may be drivenly connected to the reversing shaft of the first and second sealing portions 41, 42, respectively, via the transmission structure. The transmission structure may be configured as a sprocket, chain, or belt and pulley combination.

[0083] like Figure 9As shown, the main body 10 further includes a mounting frame 11 and a volute 12. The mounting frame 11 is provided with a connecting hole 1101, the axial direction of the connecting hole 1101 being aligned with the axial direction of the mounting frame 11. The volute 12 is positioned on one side of the mounting frame 11 in the axial direction, and the volute 12 and the mounting frame 11 cooperate to form a second chamber 102. The first chamber 101 is located on the side of the mounting frame 11 away from the second chamber 102, and the first chamber 101 and the second chamber 102 are connected through the connecting hole 1101. This arrangement provides a simple structure and facilitates assembly of the main body 10 of the ventilation component.

[0084] In this embodiment, the ventilation component further includes a cover plate 13 , which is disposed on a side of the mounting frame 11 away from the volute. The cover plate 13 and the mounting frame 11 cooperate to form a first chamber 101 .

[0085] In this embodiment, the volute 12 includes an interconnected end plate 121 and a connecting plate 122. The connecting plate 122 is annularly arranged on one side of the end plate 121. The side of the connecting plate 122, away from the end plate 121, is used to connect to the mounting bracket 11. The first air outlet 012 and the second air outlet 022 are spaced apart along the circumference of the connecting plate 122. The axis of the fan blade 30 is aligned with the axis of the connecting plate 122. Specifically, in this embodiment, the overall contour of the connecting plate 122 is generally circular. This arrangement ensures smooth fluid circulation and a high air volume.

[0086] Specifically, the fan blade 30 is mounted on the end plate 121, and the first and second sealing portions 41, 42 are both located within the volute 12, with the first and second sealing portions 41, 42 respectively located outside the fan blade 30. In other words, in this embodiment, the entire structure formed by the first sealing portion 41, the connecting portion 60, and the second sealing portion 42 is substantially located outside the fan blade 30. This arrangement ensures convenient assembly of the fan blade 30 and the volute 12. Furthermore, this arrangement prevents interference between the connecting portion 60 and the fan blade 30.

[0087] like Figure 3 and Figure 9 As shown, in this embodiment, the mounting frame 11 includes a mounting shell 111 and a partition 112. The mounting shell 111 is generally polygonal in shape, and in this embodiment, is generally pentagonal in shape. The partition 112 is disposed on one side of the mounting shell 111 in the axial direction. The first air inlet 011 and the second air inlet 021 are spaced apart along the circumference of the mounting shell 111 on the sidewall of the mounting shell 111. A connecting hole 1101 is disposed on the partition 112. The connecting hole 1101 is a circular hole coaxial with the connecting plate 122, and the fan blade 30 is coaxially disposed with the connecting hole 1101. This arrangement ensures the air volume of the ventilation components.

[0088] like Figures 9 to 12 As shown, a gap is formed between one of the side walls of the partition 112 and the inner side wall of the mounting shell 111. This gap forms a first avoidance groove. The connecting portion 60 is provided corresponding to the first avoidance groove. The first avoidance groove is used to avoid the swinging of the connecting portion 60. The mounting shell 111 is also provided with a second avoidance groove and a third avoidance groove. The second avoidance groove and the third avoidance groove are provided corresponding to the first blocking portion 41 and the second blocking portion 42, respectively. The second avoidance groove is used to avoid the movement of the first blocking portion 41, and the third avoidance groove is used to avoid the movement of the second blocking portion 42.

[0089] Furthermore, the first blocking portion 41 includes a first arc segment. When the first blocking portion 41 blocks the second air outlet 022, the first arc segment blocks the second air outlet 022, the first arc segment is coaxial with the connecting plate 122, and the outer surface of the first arc segment is in contact with the inner surface of the connecting plate 122; the second blocking portion 42 includes a second arc segment. When the second blocking portion 42 blocks the first air outlet 012, the second arc segment blocks the first air outlet 012, the second arc segment is coaxial with the connecting plate 122, and the outer surface of the second arc segment is in contact with the inner surface of the connecting plate 122. The above-mentioned arrangement enables the first blocking portion 41 to be connected to the connecting plate 122 in a circular arc transition when the first blocking portion 41 blocks the second air outlet 022, thereby improving the smoothness of fluid circulation and increasing the air volume; similarly, the above-mentioned arrangement enables the second blocking portion 42 to be connected to the connecting plate 122 in a circular arc transition when the second blocking portion 42 blocks the first air outlet 012, thereby improving the smoothness of fluid circulation and increasing the air volume.

[0090] like Figure 3 and Figure 9 As shown, in this embodiment, the ventilation component further includes a filter unit 70, which is disposed in the first chamber 101. In this embodiment, the filter unit 70 is disposed on the mounting housing 111 and is located on the side of the partition 112 away from the second chamber 102. When air flows from the first air inlet 011 to the first air outlet 012, the filter unit 70 filters the air. The provision of the filter unit 70 can filter the air and ensure the cleanliness of the air entering the room.

[0091] This solution does not limit the specific form and installation method of the filter unit 70. The filter unit 70 can be connected to the installation shell 111 by fasteners, snap-fitting or plug-in connection.

[0092] like Figure 3 、 Figures 9 to 15As shown, in this embodiment, a through hole 103 is provided on the side wall of the main body 10. Specifically, the through hole 103 is provided on the side wall of the mounting shell 111 and is in communication with the second chamber 102. The filter unit 70 is passed through the through hole 103 within the first chamber 101. This arrangement can improve the convenience of assembling the filter unit 70.

[0093] Specifically, the filter unit 70 includes a grid 71 and a filter 72 sandwiched within the grid 71. This arrangement further improves the convenience of replacing the filter unit 70.

[0094] In this embodiment, the filter unit 70 is tilted within the first chamber 101. The end of the filter unit 70 near the first air inlet 011 is tilted toward the second air outlet 022, while the end of the filter unit 70 near the second air inlet 021 is tilted away from the first air outlet 012. This arrangement ensures a sufficient filtering area for the filter unit 70.

[0095] Furthermore, in order to ensure the stability of the filter unit 70 , a positioning structure is further provided in the mounting shell 111 . The positioning structure is used to define the position of the filter unit 70 to ensure the stability of the installation of the filter unit 70 .

[0096] In this embodiment, a support bar 113 is provided in the mounting shell 111, and the support bar 113 is provided on the partition 112. The extension direction of the support bar 113 is the same as the extension direction of the through hole 103. The support bar 113 is used to abut against the surface of the end of the filter part 70 away from the through hole 103.

[0097] like Figures 3 to 5 as well as Figures 16 to 18 As shown, the ventilation component further includes a barrier portion 80, which is movably disposed within the ventilation passage 20. The barrier portion 80 has a first barrier position and a second barrier position. When the barrier portion 80 is in the first barrier position, the barrier portion 80 is used to block the first opening 201; when the barrier portion 80 is in the second barrier position, the barrier portion 80 is used to block the second opening 202. The provision of the barrier portion 80 enables the first opening 201 and the second opening 202 to be blocked or opened. Moreover, when the ventilation component is operating, when one of the first opening 201 and the second opening 202 is opened, the other is closed. In this solution, only one barrier portion 80 is required to block or open the first opening 201 and the second opening 202, further reducing the number of components of the ventilation component and lowering the cost of the ventilation component.

[0098] In some other embodiments of the present solution, two barrier portions 80 may also be provided, and the two barrier portions 80 respectively control the opening or closing of the first opening 201 and the second opening 202 .

[0099] In this embodiment, the ventilation component further includes a drive assembly 90 disposed on the main body 10 and drivingly connected to the barrier portion 80 to switch the barrier portion 80 between the first and second blocking positions. The provision of the drive assembly facilitates switching of the barrier portion 80 between the first and second blocking positions.

[0100] The present solution does not limit the specific form of the ventilation channel 20. Specifically, the ventilation channel 20 may include a plurality of pipes that are interconnected.

[0101] In this embodiment, the ventilation channel 20 comprises a duct structure, and the direction in which the ventilation channel 20 extends is the same as the direction in which the first chamber 101 extends to the second chamber 102. Specifically, along the extension direction of the ventilation channel 20, a first communication hole and a second communication hole are provided at intervals on the sidewall of the ventilation channel 20. The first communication hole communicates with the first chamber 101, and the second communication hole communicates with the second chamber 102. The barrier portion 80 is movably disposed within the ventilation channel 20 along the extension direction of the ventilation channel 20. This arrangement simplifies the structure of the ventilation component and ensures its compactness.

[0102] The present invention does not limit the specific form of the driving assembly 90, as long as it can realize the driving of the barrier portion 80. Among them, it can be set in the form of a motor and a screw that cooperate with each other, or it can be set in the form of a telescopic cylinder.

[0103] In this embodiment, the drive assembly 90 includes a second drive member 91 and a swinging portion 92. The second drive member 91 is disposed on the main body 10. The swinging portion 92 is swingably disposed within the ventilation passage 20. The swinging portion 92 has a first connecting end and a second connecting end disposed opposite each other. The first connecting end of the swinging portion 92 is hingedly connected to the sidewall of the ventilation passage 20, and the second connecting end of the swinging portion 92 is movably connected to the blocking portion 80. The second drive member 91 is drivably connected to the swinging portion 92, so that the second connecting end of the swinging portion 92 drives the blocking portion 80 to move between a first blocking position and a second blocking position. In this embodiment, the first connecting end of the swinging portion 92 is located between the first and second connecting holes. The swinging portion 92 has an initial position. When the swinging portion 92 is in the initial position, the swinging portion 92 is perpendicular to the ventilation passage 20. This arrangement ensures that when the swinging portion 92 is in the initial position, the blocking portion 80 is located between the first opening 201 and the second opening 202. That is, the second connecting end of the swinging portion 92 moves in an arc, driving the blocking portion 80 to switch between the first and second blocking positions.

[0104] Specifically, a connecting groove 801 is provided on the side wall of the barrier portion 80. The connecting groove 801 extends in the same direction as the corresponding side wall. The swing portion 92 and the connecting groove 801 are located on the same side of the barrier portion 80. The second connecting end of the swing portion 92 is movably disposed within the connecting groove 801. The provision of the connecting groove 801 can accommodate the second connecting end of the swing portion 92 and allows the swing portion 92 to be movably disposed within the connecting groove 801, thereby enabling the second driving member 91 to drive the barrier portion 80 to move via the swing portion 92.

[0105] Furthermore, the ventilation component also includes a first limiting structure and a second limiting structure. The first limiting structure is disposed within the ventilation passage 20, located at the first opening 201, and is configured to engage with the baffle 80 in a limiting manner. The second limiting structure is disposed within the ventilation passage 20, located at the second opening 202, and is configured to engage with the baffle 80 in a limiting manner. The arrangement of the first and second limiting structures limits the travel of the baffle 80, ensuring its positional accuracy.

[0106] The present solution does not limit the specific forms of the first limiting structure and the second limiting structure.

[0107] In this embodiment, a first retaining structure is annularly disposed on the inner sidewall of the first opening 201, and a second retaining structure is annularly disposed on the inner sidewall of the second opening 202. This arrangement allows the first retaining structure to function as a retaining element and also improve the seal between the baffle 80 and the ventilation passage 20. Similarly, the second retaining structure also functions as a retaining element and also improves the seal between the baffle 80 and the ventilation passage 20.

[0108] A second embodiment of the present invention provides an air conditioner, which includes the above-mentioned ventilation component.
