[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0034] like Figures 1 to 7 As shown, an embodiment of the present application provides a fresh air module 100, including: a shell 1, a driving member 2 and a transmission assembly 3.

[0035] An air duct is provided in the housing 1 , and a rotatable first air valve 41 and a second air valve 42 are provided in the air duct.

[0036] The driving member 2 is connected to the first air valve 41 and is configured to drive the first air valve 41 to rotate.

[0037] The transmission assembly 3 is connected to the driving member 2 and the second air valve 42 , and is configured to drive the second air valve 42 to rotate under the drive of the driving member 2 .

[0038] The fresh air module 100 provided in the embodiment of the present application can utilize the driving component 2 to directly drive the first air valve 41 to rotate, and can indirectly drive the second air valve 42 to rotate through the transmission component 3, so that the first air valve 41 and the second air valve 42 can share the same driving component 2, thereby reducing the number of driving components 2 and correspondingly reducing the number of driving ports, which is beneficial to reducing the cost of the fresh air module 100, simplifying the control logic of the fresh air module 100, and improving the reliability of the fresh air module 100.

[0039] In some exemplary embodiments, the air duct has a first air port 53 and a second air port 12. The first air valve 41 is configured to open or close the first air port 53. The second air valve 42 is configured to open or close at least a portion of the second air port 12.

[0040] The driving member 2 is configured to drive the first air valve 41 and the second air valve 42 to rotate in opposite directions, so that either the first air port 53 or the second air port 12 is selectively opened.

[0041] In other words, during the use of the fresh air module 100, the first air valve 41 and the second air valve 42 always operate at the same time, and the rotation directions are always opposite, so that only one of the first air outlet 53 and the second air outlet 12 can be opened, that is, when the first air outlet 53 is opened, the second air outlet 12 is closed; when the first air outlet 53 is closed, the second air outlet 12 is opened. Since the first air valve 41 and the second air valve 42 are closely connected during use, they can be controlled in linkage through the same driving member 2, which is conducive to simplifying the control logic.

[0042] In some exemplary embodiments, the second air valve 42 is configured to open or close a portion of the second air outlet 12 , and the first air valve 41 is configured to open or close the other portion of the second air outlet 12 .

[0043] like Figure 4 and Figure 5 As shown, the first air port 53 is adjacent to the second air port 12 , the rotation axis of the first air valve 41 is located between the first air port 53 and the second air port 12 , and the rotation axis of the second air valve 42 is located on the side of the second air port 12 away from the first air port 53 .

[0044] In other words, the first air valve 41 is used to control the opening and closing of the first air port 53, and is also used to cooperate with the second air valve 42 to control the opening and closing of the second air port 12. This is conducive to reducing the size of the second air valve 42 and avoiding interference between the first air valve 41 and the second air valve 42 during rotation.

[0045] Of course, the second air valve 42 may also be adapted to the second air port 12 to open or close the second air port 12 .

[0046] In some exemplary embodiments, a sealing rib 123 is provided at the second air outlet 12. Figure 4 The sealing rib 123 divides the second air outlet 12 into a first sub-air outlet 121 and a second sub-air outlet 122. Figure 1 shown.

[0047] The first air valve 41 is configured to open or close the first sub-air port 121, and the second air valve 42 is configured to open or close the second sub-air port 122. The size of the first sub-air port 121 is substantially equal to the size of the first air port 53.

[0048] The sealing rib 123 is configured to abut against the first air valve 41 and the second air valve 42 to seal the second air port 12 when the first air valve 41 and the second air valve 42 close the second air port 12 .

[0049] This helps prevent air leakage from occurring at the gap between the first air valve 41 and the second air valve 42 when the first air valve 41 and the second air valve 42 close the second air port 12, thereby helping to improve the closing reliability of the second air port 12.

[0050] In some exemplary embodiments, the driving member 2 includes a motor, and the transmission assembly 3 includes at least one of a gear rack 34 transmission mechanism, a chain transmission mechanism, and a belt transmission mechanism.

[0051] The motor may be, but is not limited to, a stepper motor. The gear rack 34 mechanism may include a plurality of gears and a plurality of racks 34 , and power transmission may be achieved through meshing. The transmission ratio may be reasonably determined according to the rotation angles of the first air valve 41 and the second air valve 42 .

[0052] Alternatively, the transmission assembly 3 may also use a chain transmission mechanism, a belt transmission mechanism, etc. for power transmission, which is also within the protection scope of the present application.

[0053] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the gear rack 34 transmission mechanism includes a first gear 31, a second gear 32, a rack 34 and a third gear 33. The third gear 33 is connected to the rotating shaft of the second air valve 42 and is configured to drive the second air valve 42 to rotate.

[0054] The first gear 31 is connected to the output shaft of the motor and is configured to rotate synchronously with the output shaft.

[0055] The second gear 32 is meshed with the first gear 31 and is configured to rotate in the opposite direction driven by the first gear 31 .

[0056] The rack 34 is meshed with the second gear 32 and the third gear 33 , and is configured to move under the drive of the second gear 32 to drive the third gear 33 to rotate in the same direction as the second gear 32 .

[0057] In this way, when the output shaft of the motor drives the first air valve 41 to rotate in the first direction, the first gear 31 also rotates in the first direction. At the same time, the first gear 31 drives the second gear 32 to rotate in the opposite second direction, the second gear 32 drives the rack 34 to move, and the rack 34 drives the third gear 33 to rotate in the second direction, so that the third gear 33 drives the second air valve 42 to rotate in the second direction. In this way, the first air valve 41 and the second air valve 42 rotate in opposite directions.

[0058] As for the parameters of the first gear 31, the second gear 32, the third gear 33 and the rack 34, they can be calculated according to the rotation angle of the first air valve 41 and the second air valve 42, combined with factors such as the number of teeth, module and transmission ratio of each gear.

[0059] The first gear 31 can be sleeved on the output shaft of the motor and rotate synchronously with the output shaft of the motor, for example, by matching a non-circular shaft and a hole to achieve synchronous rotation. Alternatively, the first gear 31 can also form an integrated structure with the output shaft of the motor.

[0060] The third gear 33 can be sleeved on the rotating shaft of the second air valve 42 and rotate synchronously with the rotating shaft of the second air valve 42, for example, by the cooperation of a non-circular shaft and a hole. Alternatively, the third gear 33 can also form an integrated structure with the rotating shaft of the second air valve 42.

[0061] A track may be provided in the housing 1, and the rack 34 is limited to the track and can move back and forth linearly along the track. A motor mounting portion and a gear mounting portion may be provided in the housing 1, the motor is mounted on the motor mounting portion, and the first gear 31, the second gear 32, and the third gear 33 are mounted on the corresponding gear mounting portions. As for the specific structural forms of the motor mounting portion and the gear mounting portion, there is no restriction, as long as they can support the motor and the gear and ensure that the motor and the gear can work normally.

[0062] In some exemplary embodiments, the first air outlet 53 is an exhaust outlet, and the second air outlet 12 is a fresh air outlet. A fresh air volute 5 is provided in the housing 1, and the fresh air volute 5 is provided with an air inlet 51 and an air outlet 52. Figure 1 , Figure 4 and Figure 5 As shown. The housing 1 is provided with a fresh air inlet 13 and an exhaust air inlet. The air duct includes a fresh air duct and an exhaust air duct. The exhaust air outlet can be provided in the fresh air volute 5, and the fresh air outlet can be provided in the housing 1.

[0063] The fresh air duct includes an air flow channel formed by connecting the fresh air inlet 13, the air inlet 51, the air outlet 52, and the fresh air outlet.

[0064] The exhaust air duct includes an air flow channel formed by connecting the exhaust inlet, the air inlet 51, the air outlet 52, the exhaust outlet, and the fresh air inlet 13.

[0065] The fresh air module 100 further includes a third air valve and a fourth air valve. The third air valve is configured to control the opening and closing of the fresh air inlet 13, and the fourth air valve is configured to control the opening and closing of the exhaust air inlet.

[0066] In this way, the fresh air duct and the exhaust air duct can share a part of the air flow channel, that is, the air flow channel in the fresh air volute 5, and can also share a fan, which is beneficial to simplify the structure of the fresh air module 100 and reduce the cost of the fresh air module 100.

[0067] Moreover, the fresh air inlet 13 is used for both outdoor fresh air to enter the fresh air module 100 and indoor polluted air to flow out of the fresh air module 100. In this way, outdoor fresh air can enter the room and indoor polluted air can be discharged to the outside through a fresh air duct connected to the fresh air inlet 13, thereby eliminating an exhaust duct, which is beneficial to simplifying the structure of the fresh air module 100 and reducing the cost of the fresh air module 100.

[0068] The central axis of the air inlet 51 can be arranged along the axial direction of the fresh air volute 5. The fresh air inlet 13 and the fresh air outlet can be arranged on adjacent side panels of the housing 1. The exhaust air inlet can be arranged on the cover plate of the housing 1. The exhaust air inlet can be arranged with a relative spacing from the air inlet 51. The exhaust air outlet can be located between the fresh air outlet and the fresh air inlet 13.

[0069] The third air valve and the fourth air valve can be driven by corresponding driving members 2 to control the opening and closing of the fresh air inlet 13 and the exhaust air inlet respectively.

[0070] In some exemplary embodiments, the housing 1 is further provided with a switch port 54 that can communicate with the fresh air inlet 13. Figure 2 and Figure 4 As shown. The fresh air inlet 13 is configured to be able to communicate with the air inlet 51 through the switching port 54. The fresh air inlet 13 is configured to be able to communicate with the switching port 54 and the exhaust outlet to switch the airflow direction of the fresh air inlet 13. The switching port 54 can be set on the fresh air volute 5. The fresh air module 100 also includes a fifth air valve, which is used to control the opening and closing of the switching port 54. The fifth air valve can be driven by the corresponding driving member 2.

[0071] In other words, the switch port 54 cooperates with the exhaust outlet to control the airflow direction of the fresh air module 100, so that the fresh air module 100 switches between the fresh air mode and the exhaust mode. The fresh air mode refers to a working mode that introduces outdoor fresh air into the indoor space. The exhaust mode refers to a working mode that exhausts indoor dirty air to the outdoors.

[0072] The exhaust outlet and the switch port 54 are arranged to selectively communicate with the fresh air inlet 13. In other words, the exhaust outlet and the switch port 54 cannot be communicated with the fresh air inlet 13 at the same time, and only one can be communicated with the fresh air inlet 13 in the same working mode.

[0073] The fresh air inlet 13 is arranged to be connected to the air inlet 51 through the switching port 54. That is, in the fresh air mode, the fresh air inlet 13 is connected to the switching port 54 and is separated from the exhaust outlet. The switching port 54 is located at the downstream side of the fresh air inlet 13 and at the upstream side of the air inlet 51. The fresh air flows through the fresh air inlet 13, the switching port 54, the air inlet 51, the air outlet 52 and the exhaust outlet in sequence. Figure 1 and Figure 4In the exhaust mode, the fresh air inlet 13 is connected to the exhaust outlet and is separated from the switch port 54. The exhaust outlet is located at the downstream side of the air inlet 51 and at the upstream side of the fresh air inlet 13. The indoor polluted air flows through the exhaust inlet, the air inlet 51, the exhaust outlet and the fresh air inlet 13 in sequence. Figure 5 and Figure 7 shown.

[0074] In this way, the working mode of the fresh air module 100 can be switched by opening and closing the switching port 54 and opening and closing the exhaust outlet, thereby realizing the switching between the fresh air mode and the exhaust mode. The structure is simple and easy to implement.

[0075] When the switch port 54 is opened and the exhaust outlet is closed, the fresh air inlet 13 can be connected to the switch port 54 and isolated from the exhaust outlet, so that the outdoor fresh air can flow through the fresh air inlet 13, the switch port 54, the air inlet 51, and the fresh air outlet in sequence and enter the indoor space. Figure 1 and Figure 4 shown.

[0076] When the switch port 54 is closed and the exhaust outlet is opened, the fresh air inlet 13 can be connected to the exhaust outlet and isolated from the switch port 54, so that the indoor polluted air can flow through the exhaust inlet, the air inlet 51, the exhaust outlet, and the fresh air inlet 13 in sequence and be discharged to the outdoor space. Figure 5 and Figure 7 shown.

[0077] In some exemplary embodiments, the air duct further includes an inner circulation air duct, which includes an air flow channel formed by connecting an exhaust air inlet, an air inlet 51, an air outlet 52, and a fresh air outlet.

[0078] In this way, the fresh air module 100 also has an internal circulation mode, which can drive the indoor air flow. When the fresh air module 100 operates in the internal circulation mode, Figure 6 As shown, the fresh air inlet 13 is closed, the exhaust outlet is closed, the switching port 54 is closed, the exhaust inlet is opened, and the fresh air outlet is opened. The indoor air enters the fresh air module 100 through the exhaust inlet, flows through the air inlet 51 and the air outlet 52 of the fresh air volute 5 in sequence, and is then discharged into the room through the fresh air outlet, thereby realizing the circulation of indoor air.

[0079] In some exemplary embodiments, the fresh air module 100 further includes a filter 6, such as Figure 5 and Figure 6 As shown, it is arranged at the fresh air outlet and is configured to filter and purify the airflow passing through the fresh air outlet.

[0080] Since the air is discharged into the room from the fresh air outlet in both the fresh air mode and the internal circulation mode, the filter 6 at the fresh air outlet can filter and purify the airflow in the fresh air mode and the internal circulation mode, thereby improving the quality of the fresh air and enabling the internal circulation mode to purify the indoor air.

[0081] In some exemplary embodiments, the fresh air module 100 further includes a carbon dioxide sensor (not shown in the figure) configured to detect the carbon dioxide concentration of the indoor air.

[0082] The fresh air module 100 further includes a TVOC sensor (not shown in the figure), which is configured to detect the TVOC concentration of the indoor air. TVOC, which is the abbreviation of Total Volatile Organic Compounds, refers to total volatile organic compounds.

[0083] This makes it easy to reasonably control the working mode of the fresh air module 100 according to the detection results of the carbon dioxide sensor and the TVOC sensor, thereby helping to improve user experience.

[0084] For example, when the TVOC sensor detects that the indoor air quality is poor (TVOC concentration is high), the fresh air module 100 can automatically turn on the exhaust mode to exhaust the indoor polluted air to the outside. When the carbon dioxide sensor detects that the indoor carbon dioxide concentration is high, the fresh air module 100 automatically turns on the fresh air mode to introduce outdoor fresh air into the room to increase the oxygen content of the indoor air.

[0085] The TVOC sensor and the carbon dioxide concentration sensor may be arranged in the return air area of ​​the fresh air module 100 , for example, at the exhaust air inlet of the fresh air module 100 .

[0086] In some embodiments, the fresh air module 100 can realize three-way fresh air system modes, namely fresh air mode, exhaust mode and internal circulation mode, which is beneficial to improve product comfort and enhance indoor air quality.

[0087] For fresh air mode (such as Figure 1 and Figure 4 As shown in FIG. 1 , the fresh air inlet 13 is opened, the switch port 54 is opened, the exhaust outlet is closed, the exhaust inlet is closed, and the fresh air outlet is opened. The fan is started to introduce fresh air from the outside, and the fresh air is filtered and purified by the filter 6 at the fresh air outlet and then discharged into the room, thereby achieving the purpose of introducing fresh air.

[0088] For exhaust mode (such as Figure 5 and Figure 7As shown in the figure): the fresh air inlet 13 is opened, the switch port 54 is closed, the exhaust outlet is opened, the exhaust inlet is opened, and the fresh air outlet is closed. The fan is started to introduce polluted air from the room, and the polluted air is directly discharged from the fresh air inlet 13 without being filtered by the filter 6, and is discharged to the outside through the fresh air duct, thereby achieving the effect of exhausting polluted air.

[0089] For the internal circulation mode (also called indoor purification mode, such as Figure 6 As shown in FIG. 1 , the fresh air inlet 13 is closed, the switch port 54 is closed, the exhaust outlet is closed, the exhaust inlet is opened, and the fresh air outlet is opened. The fan is started, and the indoor air enters the fresh air module 100, and is filtered and purified by the filter 6 at the fresh air outlet before being discharged into the room, thereby achieving the purpose of internal circulation and purification of indoor air.

[0090] Among them, according to the speed of the fan in the fresh air mode, it can also be divided into a sleep mode with a low speed and a strong mode with a high speed.

[0091] The fresh air device may also have an intelligent mode, which can automatically control the fresh air module 100 according to the air quality detection results. The control method of the intelligent mode includes:

[0092] In response to the power-on instruction, determining whether the carbon dioxide concentration of the indoor air is greater than a set carbon dioxide concentration value;

[0093] Based on the fact that the carbon dioxide concentration in the indoor air is greater than the set carbon dioxide concentration value, it is determined whether to enter the sleep mode; based on the determination of entering the sleep mode, the fresh air module 100 is controlled to enter the sleep mode; based on the determination of not entering the sleep mode, the fresh air module 100 is controlled to enter the strong mode

[0094] Based on the fact that the carbon dioxide concentration of the indoor air is not greater than the set carbon dioxide concentration value, determining whether the TVOC concentration of the indoor air is greater than the set TVOC concentration value;

[0095] Based on the fact that the TVOC concentration of the indoor air is greater than the set TVOC concentration value, the fresh air module 100 is controlled to enter the exhaust mode;

[0096] Based on the fact that the TVOC concentration of the indoor air is not greater than the set TVOC concentration value, the fresh air module 100 is controlled to enter a standby state or a manual operation state (ie, exit the smart mode).

[0097] like Figure 8 As shown, an embodiment of the present application further provides an air conditioner, comprising: an air conditioner main body 7 and a fresh air module 100 as in any one of the above embodiments, connected to the air conditioner main body 7 .

[0098] The air conditioner provided in the embodiment of the present application includes the fresh air module 100 of any one of the above embodiments, and thus has all the above beneficial effects, which will not be elaborated here.

[0099] The type of air conditioner is not limited, and may be, but not limited to, a duct air conditioner, a wall-mounted air conditioner, a cabinet air conditioner, a vertical air conditioner, a floor-standing air conditioner, etc. The air conditioner body 7 may include an air conditioner indoor unit and an air conditioner outdoor unit, and the fresh air module 100 is connected to the air conditioner indoor unit.

[0100] Of course, the fresh air module 100 provided in the embodiment of the present application is not limited to use in air conditioners, but can also be used in other types of air treatment equipment, such as air purifiers, humidifiers, dehumidifiers, sterilizers, etc.

[0101] In some embodiments, the air conditioner may be, but is not limited to, a duct air conditioner. The fresh air module 100 may be located on one side of the length direction of the duct air conditioner body and connected to the duct air conditioner body. Of course, the fresh air module 100 may also be located on one side or other positions of the width direction of the duct air conditioner body, which may be reasonably determined according to different installation scenarios and installation requirements of customers. The fresh air module 100 is connected to the fresh air duct by a hose.

[0102] The up and down directions marked in the drawings of the specification are based on the state of the duct unit after it is concealed in the ceiling after leaving the factory, with the direction toward the ground being down and the direction toward the ceiling being up, for example, the air inlet 51 of the fresh air volute 5 and the fresh air inlet 13 of the housing 1 facing down. However, during the assembly process of the duct unit before leaving the factory, the up and down directions can be changed, for example, the air inlet 51 of the fresh air volute 5 and the fresh air inlet 13 of the housing 1 facing up.
