Description

Technical Field

[0001] The present application relates to the field of fresh air technology, for example, to a fresh air module and an air conditioner. Background Art

[0002] At present, air conditioners, also known as air conditioners, can regulate and control ambient air, including regulating and controlling parameters such as ambient temperature and humidity. Air conditioners usually include an indoor unit and an outdoor unit. The outdoor unit is responsible for cooling or heating, and the indoor unit is responsible for delivering cold air or hot air to the room. As people's living standards improve, people pay more and more attention to the quality of life and have higher and higher health needs, making air conditioners with fresh air modules the choice of more and more people. The air conditioner replaces fresh air in the indoor environment through the fresh air module. In the prior art, the fresh air module replaces the air through the fresh air duct. However, the fresh air duct in the prior art is usually a one-way duct, which can only suck the air from the outdoor side into the indoor side, but cannot discharge the air from the indoor side to the outdoor side, so it is impossible to achieve the balance of air intake and exhaust of the air conditioning system.

[0003] A fresh air module is disclosed in the related technology, comprising: an air duct, which is connected to the indoor side and the outdoor side respectively, and the air duct is separated to form an intake duct and an exhaust duct; a driving structure, which is partially or completely located in the air duct; and a fan assembly, including a first fan located in the intake duct, and also including a second fan located in the exhaust duct, and the first fan and the second fan have opposite directions of rotation; the first fan and the second fan are both connected to the driving structure, and are driven by the driving structure to rotate in opposite directions, so that fresh air from the outdoor side enters the indoor side through the intake duct, and the stale air from the indoor side is discharged to the outdoor side through the exhaust duct.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] When the fresh air module of the related technology turns on two-way fresh air, the numerical ratio of the fresh air volume and the exhaust air volume is fixed. However, the fresh air volume and the exhaust air volume also need to change according to the user's needs in different scenarios. When increasing the fresh air volume or increasing the exhaust air volume, the existing fresh air module can only increase the air volume by increasing the speed of the fan assembly, which will increase the noise of the fresh air module and cannot meet user needs.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0052] Combination Figures 1 to 6 As shown, Figures 4 to 6 The middle arrow indicates the direction of air flow. The embodiment of the present disclosure provides a fresh air module, which includes: a main housing 10, a sub-housing 20, a fresh air duct 30, an exhaust duct 40 and a guide plate 50. The main housing 10 is provided with a fresh air inlet 101, a fresh air outlet 102, a turbid air inlet 103 and a turbid air outlet 104; the sub-housing 20 defines a first flow channel with an air outlet 202 and a second flow channel with an air inlet 201. The first flow channel is connected to the fresh air duct 30, the second flow channel is connected to the exhaust duct 40, and the air outlet 202 is connected to the fresh air inlet 101. The air inlet 101 is connected, and the air inlet 201 is connected to the dirty air outlet 104; the first end of the fresh air duct 30 is connected to the first flow channel of the sub-shell 20, and the second end of the fresh air duct 30 extends to the outdoors; the first end of the exhaust duct 40 is connected to the second flow channel of the sub-shell 20, and the second end of the exhaust duct 40 extends to the outdoors; the guide plate 50 is rotatably disposed in the sub-shell 20, and the guide plate 50 is located between the first flow channel and the second flow channel, and is used to adjust the connection area between the first flow channel and the fresh air duct and the connection area between the second flow channel and the exhaust duct 40.

[0053] According to the embodiment of the present disclosure, by providing a fresh air inlet 101, a fresh air outlet 102, a dirty air inlet 103 and a dirty air outlet 104 in the main housing 10, outdoor fresh air can flow into the main housing 10 from the fresh air inlet 101 and flow out of the main housing 10 from the fresh air outlet 102, and indoor dirty air can flow into the main housing 10 from the dirty air inlet 103 and flow out of the main housing 10 from the dirty air outlet 104. By providing a sub-housing 20, a fresh air duct 30 and an exhaust duct 40, outside air can flow into the sub-housing 20 along the fresh air duct 30 and flow into the main housing 10 through the air outlet 202 along the first flow channel, and indoor dirty air flowing out of the main housing 10 can flow into the sub-housing 20 from the air inlet 201 and flow out to the outdoors from the exhaust duct 40 along the second flow channel, so that fresh air can smoothly enter the room and dirty air in the room can be effectively discharged.

[0054] By setting the guide plate 50 and rotatably setting the guide plate 50, the guide plate 50 can change the connection area between the first flow channel and the fresh air duct. By increasing or decreasing the connection area between the first flow channel and the fresh air duct 30, the size of the fresh air volume can be adjusted. By increasing or decreasing the connection area between the second flow channel and the exhaust duct 40, the size of the exhaust air volume can be adjusted. Compared with the fresh air module in the related art, this embodiment does not need to increase the speed of the fan when increasing the fresh air volume or exhaust air volume, which will not cause the problem of increased noise, thereby improving the user experience.

[0055] Optionally, the exhaust duct 40 and the fresh air duct 30 are arranged side by side.

[0056] In this way, installation space can be saved, space utilization can be improved, and installation of the fresh air duct 30 and the exhaust duct 40 can be facilitated.

[0057] Optionally, the diameter of the fresh air duct 30 is larger than the diameter of the exhaust air duct 40 .

[0058] In this way, the fresh air volume can be ensured to be greater than the exhaust air volume, avoiding the occurrence of negative pressure in the room.

[0059] Specifically, the sub-shell 20 includes a shell and a cavity plate, the shell is provided with an air inlet 201, an air outlet 202, a fresh air pipe port 203 and an exhaust air pipe port 204, the cavity plate divides the internal space of the sub-shell 20 into a first flow channel and a second flow channel, one end of the first flow channel is connected to the air outlet 202, the other end of the first flow channel is connected to the fresh air pipe port 203, one end of the second flow channel is connected to the air inlet 201, and the other end of the second flow channel is connected to the exhaust air pipe port 204. Among them, the guide plate 50 is rotatably connected to the cavity plate and is arranged between the fresh air pipe port 203 and the exhaust air pipe port 204 to control the connection area between the first flow channel and the fresh air pipe port 203 and the flow area between the second flow channel and the exhaust air pipe port 204.

[0060] In this way, the chamber dividing plate divides the internal space of the sub-housing 20 into a first flow channel and a second flow channel, so that the fresh air and the exhaust air are completely separated physically, avoiding the possibility of cross contamination. The guide plate 50 is rotatably connected to the chamber dividing plate and is arranged between the fresh air pipe port 203 and the exhaust air pipe port 204, so that the guide plate 50 can flexibly adjust its angle and position, thereby controlling the connection area between the first flow channel and the fresh air pipe port 203 and the flow area between the second flow channel and the exhaust air pipe port 204.

[0061] Optionally, the fresh air module also includes: a first partition 61, which is arranged in the fresh air duct 30 and extends into the sub-shell 20, and is used to separate the fresh air duct 30 into two flow channels; wherein, the guide plate 50 has a first position, when the guide plate 50 rotates to the first position, the guide plate 50 abuts against the first partition 61, and one of the two flow channels of the fresh air duct is connected to the first flow channel, and the other flow channel is connected to the second flow channel.

[0062] In the embodiment of the present disclosure, by setting the first partition 61, the first partition 61 divides the fresh air duct into two flow channels, so that the fresh air is divided into two different flow paths before entering the sub-shell 20, and the guide plate 50 can be rotated to different positions as needed. When the guide plate 50 is rotated to the first position, it can abut against the first partition 61, thereby changing the connection between the fresh air duct and the flow channel in the sub-shell 20. Figure 4As shown in, when the guide plate 50 is in the first position, the guide plate 50 abuts against the end of the first partition plate 61, and one of the two flow channels in the fresh air duct is connected to the first flow channel, and the other flow channel is connected to the second flow channel. In this way, the flow channel of the fresh air duct connected to the first flow channel provides fresh air, and the flow channel of the fresh air duct connected to the second flow channel and the exhaust duct 40 are used for exhaust, which can effectively increase the exhaust volume. In addition, the arrangement of the first partition plate 61 and the guide plate 50 helps to stabilize the flow state of the airflow in the pipeline and the sub-shell 20, reduce the noise and vibration caused by unstable airflow, and thus avoid the problem of increased noise due to changing the flow channel area.

[0063] Optionally, there are multiple first partitions 61 , which are evenly spaced apart; the guide plate 50 has multiple first positions, and when the guide plate 50 is in any first position, the guide plate 50 abuts against the corresponding first partition 61 .

[0064] By adopting the embodiment of the present disclosure, by setting a plurality of first baffles 61, more gears of air volume adjustment can be achieved, so that the ratio adjustment between the fresh air volume and the exhaust air volume is more delicate and accurate, and the ventilation requirements under different environmental conditions are met. By setting a plurality of first baffles 61 at even intervals, the flow of fresh air in the duct can be made more uniform, reducing airflow dead angles and vortex phenomena.

[0065] Optionally, the fresh air module further includes an air guide plate, which is rotatably disposed at the outdoor end of the fresh air duct, and the air guide plate is rotatably connected to the first partition plate 61.

[0066] In this way, by rotating the air guide plate, the air inlet direction and air outlet direction of the outdoor end of each flow channel of the fresh air duct can be changed, thereby preventing the fresh air duct from sucking in the turbid air discharged from the room and preventing the turbid air from being back-injected.

[0067] Optionally, the fresh air module also includes: a second partition 62, which is arranged in the exhaust duct 40 and extends into the sub-shell 20, and the second partition 62 is used to separate the exhaust duct 40 into two flow channels; wherein, the guide plate 50 has a second position, when the guide plate 50 rotates to the second position, the guide plate 50 abuts against the second partition 62, and one of the two flow channels of the exhaust duct 40 is connected to the first flow channel, and the other flow channel is connected to the second flow channel.

[0068] According to the embodiment of the present disclosure, by providing a second partition plate 62, the second partition plate 62 divides the fresh air duct into two flow paths, so that the fresh air is divided into two different flow paths before entering the sub-shell 20, and the guide plate 50 can be rotated to different positions as needed. When the guide plate 50 is rotated to the second position, it can abut against the second partition plate 62, thereby changing the communication between the exhaust duct 40 and the flow path in the sub-shell 20. Figure 5As shown in , when the guide plate 50 is in the second position, the guide plate 50 abuts against the end of the second partition plate 62, and one of the two flow channels in the exhaust duct 40 is connected to the first flow channel, and the other flow channel is connected to the second flow channel. In this way, the flow channel of the exhaust duct 40 connected to the first flow channel provides fresh air, and the flow channel of the exhaust duct 40 connected to the second flow channel exhausts air, which can effectively increase the amount of fresh air. In addition, the arrangement of the second partition plate 62 and the guide plate 50 helps to stabilize the flow state of the airflow in the pipeline and the sub-shell 20, reduce the noise and vibration caused by the unstable airflow, and thus avoid the problem of increased noise caused by changing the flow channel area.

[0069] Optionally, there are multiple second partitions 62 , which are evenly spaced apart; the guide plate 50 has multiple second positions, and when the guide plate 50 is at any second position, the guide plate 50 abuts against the corresponding second partition 62 .

[0070] By adopting the embodiment of the present disclosure, by setting a plurality of second baffles 62, more gears of air volume adjustment can be achieved, so that the ratio adjustment between the fresh air volume and the exhaust air volume is more delicate and accurate, and the ventilation requirements under different environmental conditions are met. By setting a plurality of second baffles 62 at even intervals, the exhaust air can flow more evenly in the exhaust duct 40, reducing airflow dead angles and vortex phenomena.

[0071] Optionally, the fresh air module also includes: a third partition 63, which is arranged in the sub-shell 20, and the third partition 63 is located at the separation between the first flow channel and the second flow channel and is arranged corresponding to the guide plate 50; wherein, the guide plate 50 has a third position, and when the guide plate 50 rotates to the third position, the guide plate 50 abuts against the third partition 63.

[0072] With the disclosed embodiment, the provision of the third partition plate 63 further enhances the separation effect between the first flow channel and the second flow channel, ensuring that the fresh air and the exhaust air are completely separated in the sub-shell 20, thereby avoiding the possibility of cross-contamination. Through the guidance of the third partition plate 63, the flow paths of the fresh air and the filthy air in the sub-shell 20 are more clear and efficient. This helps to reduce the resistance to air flow and improve the ventilation efficiency of the system. The guide plate 50 has a third position, and when the guide plate 50 is rotated to the third position, it abuts against the third partition plate 63. The third partition plate 63 cooperates with the guide plate 50 to avoid cross-contamination between outdoor fresh air and indoor filthy air.

[0073] Optionally, the length dimension of the third partition is smaller than the length dimension of the first partition, and the length dimension of the third partition is smaller than the length dimension of the second partition.

[0074] In this way, it can be ensured that when the guide plate 50 is connected to each partition, an effective airflow barrier can be formed at the connection portion between the guide plate and each partition, thereby avoiding mixing of airflows between different flow channels.

[0075] Optionally, the fresh air module further includes: a motor 70 , which is disposed in the sub-housing 20 and is drivingly connected to the guide plate 50 , and is used to control the rotation of the guide plate 50 .

[0076] By adopting the embodiment of the present disclosure, by setting a motor 70 and using the motor 70 to drive the guide plate 50, the user no longer needs to manually adjust the position of the guide plate 50, and can achieve precise control of the rotation position of the guide plate 50 by simply using a corresponding control device or system. This not only improves the convenience of operation, but also reduces the adjustment error caused by human factors, thereby ensuring the precise control of the fresh air volume and exhaust air volume. Secondly, the motor 70 can provide continuous and precise rotation angle control, so that the rotation of the guide plate 50 is smoother and continuous, which helps to avoid the noise and vibration generated by the guide plate 50 during the rotation process, and further enhances the user experience. In addition, the motor 70 can also improve the response speed and adjustment efficiency of the fresh air module. When the fresh air volume or exhaust air volume needs to be adjusted, the motor 70 can respond quickly and drive the guide plate 50 to make corresponding adjustments.

[0077] Specifically, the motor 70 is a stepper motor, which is disposed outside the sub-housing 20 , and the stepper motor is detachably connected to the sub-housing 20 .

[0078] In this way, the stepper motor has the characteristics of high-precision positioning and can accurately control the rotation angle and position of the guide plate 50. This ensures the precise adjustment of the fresh air volume and exhaust air volume, avoids errors and fluctuations in air volume adjustment, and thus provides users with a more stable and comfortable environment. By arranging the stepper motor outside the sub-housing 20 and the stepper motor being detachably connected to the sub-housing 20, on the one hand, it is convenient for the maintenance and replacement of the stepper motor. When the stepper motor fails or needs repair, the user can easily disassemble and install it; on the other hand, the internal space of the sub-housing 20 can be fully utilized, and a more compact internal air duct structure can be designed to optimize the volume and weight of the overall fresh air system. In addition, stepper motors generally have lower noise and vibration levels, which makes the fresh air module quieter and smoother during operation.

[0079] Optionally, the main shell 10 defines a fresh air portion 11 and an exhaust portion 12, the fresh air portion 11 and the exhaust portion 12 are arranged side by side, and the exhaust portion 12 and the fresh air portion 11 are independent of each other, the fresh air portion 11 includes a fresh air volute 111 and a fresh air impeller 112, the fresh air impeller 112 is rotatably disposed in the fresh air volute 111, the exhaust portion 12 includes an exhaust volute 121 and an exhaust impeller 122, the exhaust impeller 122 is rotatably disposed in the exhaust volute 121; the fresh air module also includes: a driving motor 80, which is arranged between the exhaust portion 12 and the fresh air portion 11, and is drivingly connected to both the exhaust impeller 122 and the fresh air impeller 112, for driving the exhaust impeller 122 and the fresh air impeller 112 to rotate synchronously.

[0080] According to the disclosed embodiment, the fresh air section 11 and the exhaust section 12 are independently arranged, and both the fresh air section 11 and the exhaust section 12 have a complete fresh air volute 111 and a fresh air impeller 112, an exhaust volute 121 and an exhaust impeller 122 structure, so as to ensure that the fresh air introduction and the indoor turbid air discharge process will not interfere with each other, and the fresh air section 11 and the exhaust section 12 can respectively and efficiently complete their respective functional tasks. By arranging a drive motor 80 and driving and connecting the drive motor 80 with the exhaust impeller 122 and the fresh air impeller 112, the drive motor 80 can simultaneously drive the fresh air impeller 112 and the exhaust impeller 122 to rotate, so as to realize the coordinated action of fresh air intake and indoor air extraction. Two impellers can be driven to work by one motor, so as to avoid the waste of resources of configuring two power systems separately, improve the energy utilization rate, ensure the synchronization of fresh air and exhaust air, and help improve the operation efficiency of the entire fresh air air conditioner indoor unit. Moreover, the fresh air part 11 and the exhaust part 12 are arranged side by side, making the structure of the whole fresh air module more compact and saving the space of the air conditioner indoor unit. In this embodiment, the fresh air volume and the exhaust air volume can be adjusted simultaneously without arranging two drive motors 80 .

[0081] Optionally, the thickness of the exhaust impeller 122 is less than or equal to half of the thickness of the fresh air impeller 112 .

[0082] By adopting the embodiment of the present disclosure, by setting the thickness of the exhaust impeller 122 to be less than or equal to half of the thickness of the fresh air impeller 112, on the one hand, the overall volume of the exhaust part 12 can be reduced, thereby reducing the thickness and occupied space of the fresh air module; on the other hand, it helps to balance the air volume of exhaust air and fresh air, ensuring that the two can maintain a relatively stable air volume ratio during operation, and avoiding the situation where the exhaust air volume is greater than the fresh air volume, causing negative pressure in the room.
