Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a fresh air module, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] With the development of technology and the improvement of people's living standards, air conditioners, as an essential home appliance for air conditioning, are increasingly demanded by users for comfort.

[0003] Current air conditioners circulate indoor air to heat or cool it when heating or cooling. At the same time, in order to maintain the indoor temperature, users often keep doors and windows tightly closed, which leads to increasingly poor indoor air quality, lower oxygen content, and continuously increasing particulate matter concentration. Users are prone to symptoms such as dizziness, which affects their health.

[0004] To avoid indoor air quality problems such as excessively high carbon dioxide concentrations caused by poor ventilation, fresh air conditioning systems typically include a fresh air unit that connects to the outdoor environment, introducing outdoor air into the indoor space. However, existing fresh air conditioning systems generally only introduce outdoor air into the room and cannot remove stale indoor air, making their function relatively limited and unable to quickly and effectively replace indoor and outdoor air.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0054] This application provides a fresh air module, which will be described in detail below.

[0055] Please see Figures 1 to 5 In this embodiment of the application, the fresh air module 100 includes:

[0056] The volute 10 defines a first chamber 11, and an indoor air outlet 12 communicating with the first chamber 11 is provided on the side wall of the volute 10.

[0057] Fan 20, wherein the fan 20 is disposed in the first chamber 11;

[0058] An air inlet hood 30 is provided, which is divided into a second chamber 31 and a third chamber 32. An air inlet slide plate 40 is slidably disposed between the second chamber 31 and the third chamber 32. An upper air inlet 33, a middle air inlet 34 and a lower air inlet 35 are provided on the side wall of the air inlet hood 30.

[0059] The lifting mechanism 50 is provided with an exhaust duct 521 and a lifting bracket 51 is provided at the indoor air outlet 12.

[0060] The lifting mechanism 50 is used to simultaneously drive the lifting bracket 51 and the air inlet slide plate 40, so that the lower air outlet 35 of the hood, the third chamber 32, the second chamber 31, the first chamber 11 and the indoor air outlet 12 are connected in sequence to form an air inlet path, or the upper air outlet 33 of the hood, the second chamber 31, the first chamber 11, the indoor air outlet 12, the exhaust channel 521, the middle air outlet 34 of the hood, the third chamber 32 and the lower air outlet 35 of the hood are connected to form an exhaust path.

[0061] It is understood that the fresh air module 100 proposed in this application can realize both fresh air intake and stale air exhaust. Please refer to the following: Figures 6 to 8 , Figures 6 to 8 The diagram shows the air intake path of the fresh air module 100. When fresh air is needed, the fan 20 operates. Simultaneously, the lifting mechanism 50 controls the lifting bracket 51 to open the indoor air outlet 12, and controls the air intake slide plate 40 to slide and block the upper air outlet 33 of the air hood. At this time, the lower air outlet 35 of the air hood, the third chamber 32, the second chamber 31, the first chamber 11, and the indoor air outlet 12 are sequentially connected to form the air intake path. Please refer to the attached diagram. Figures 9 to 12 , Figures 9 to 12 The diagram illustrates the exhaust path of the fresh air module 100. When stale air needs to be exhausted, the fan 20 operates. Simultaneously, the lifting mechanism 50 controls the lifting bracket 51 to close the indoor air outlet 12, and controls the air inlet slide plate 40 to slide and open the upper air vent 33 of the hood, blocking the connection between the third chamber 32 and the second chamber 31. At this time, the upper air vent 33 of the hood, the second chamber 31, the first chamber 11, the indoor air outlet 12, the exhaust channel 521, the middle air vent 34 of the hood, the third chamber 32, and the lower air vent 35 of the hood are connected to form an exhaust path. The fresh air module 100 proposed in this application achieves switching between the air inlet and exhaust paths by simultaneously controlling the lifting bracket 51 of the indoor air outlet 12 and the air inlet slide plate 40 within the air inlet hood 30, enabling the fresh air air conditioner to have both fresh air and exhaust functions.

[0062] Specifically, please refer to the following: Figure 4 and Figure 5In this embodiment, the air inlet hood 30 is provided with a sliding cavity 36 and a guide rib 37. The air inlet slide plate 40 is attached to the guide rib 37, and both ends of the air inlet slide plate 40 can be accommodated in the sliding cavity 36. The air inlet slide plate 40 is provided with an upper air inlet 41 and a lower air inlet 42. The air inlet slide plate 40 has a first position and a second position. When the air inlet slide plate 40 is in the first position, the lower air inlet 35 of the hood is connected to the outdoor space through the lower air inlet 42 of the slide plate, and the upper air inlet 41 of the slide plate is blocked by the guide rib 37. When the air inlet slide plate 40 is in the second position, the upper air inlet 33 of the hood is connected to the indoor space through the upper air inlet 41 of the slide plate, and the lower air inlet 42 of the slide plate is blocked by the guide rib 37. It is understood that the air inlet slide plate 40 is an arc-shaped plate, which, together with the sliding cavity 36 and the guide rib 37, divides the air inlet hood 30 into the second chamber 31 and the third chamber 32. When the air inlet slide plate 40 rotates downward, the upper air outlet 41 of the slide plate moves downward to avoid the upper air outlet 33 of the hood, thereby blocking the communication between the upper air outlet 33 of the hood and the second chamber 31; simultaneously, the lower air outlet 42 of the slide plate moves to the lower air outlet 35 of the hood, so that the lower air outlet 35 of the hood communicates with the second chamber 31, and then the fan 20 works, and outdoor air enters the second chamber 31 through the lower air outlet 35 of the hood, and then is delivered to the room through the indoor air outlet 12 via the first chamber 11. When the air inlet slide plate 40 rotates upward, the upper air vent 41 of the slide plate moves upward to the upper air vent 33 of the air cover, thereby connecting the upper air vent 33 of the air cover with the second chamber 31; simultaneously, the lower air vent 42 of the slide plate moves to the guide rib 37, thereby blocking the connection between the third chamber 32 and the second chamber 31, and then the fan 20 operates, and indoor air enters the second chamber 31 from the upper air vent 33 of the air cover, and then enters the third chamber 32 from the middle air vent 34 of the air cover through the first chamber 11, the indoor air outlet 12 and the exhaust channel 521, and finally is discharged to the outside from the lower air vent 35 of the air cover.

[0063] Specifically, in one embodiment of this application, the guide rib 37 is arranged in an arc shape, and the center of the arc is on the same straight line as the rotation axis of the fan 20. It can be understood that when fresh air enters the second chamber 31 through the air outlet 35 under the hood, the arc-shaped guide rib 37 can guide the incoming fresh air, making the air intake smoother.

[0064] Furthermore, the sidewalls of the air inlet hood 30 adjacent to the third chamber 32 are arranged in an arc shape, and the center of the arc is on the same straight line as the rotation axis of the fan 20. It can be understood that designing the sidewalls of the air inlet hood and the third chamber as arc-shaped, which together with the guide rib 37 form the arc-shaped third chamber 32, saves space while achieving the exhaust function, thus improving the utilization rate of the air inlet hood 30.

[0065] Furthermore, please refer to the following: Figure 2 and Figure 3 In this embodiment, the lifting mechanism 50 includes a fixed base 52, a lifting base 53, and a drive assembly 54. The fixed base 52 is disposed on the side of the air inlet hood 30 away from the volute 10, and the fixed base 52 is provided with the exhaust channel 521, one end of which is connected to the air outlet 34 in the air hood; the lifting base 53 is provided with a first air outlet 531 and a second air outlet 532 that are connected, the first air outlet 531 being connected to the other end of the exhaust channel 521, and the second air outlet 532 being connected to the indoor air outlet 12; the lifting bracket 51 is disposed on the lifting base 53 and is used to close or open the first air outlet 531 and the second air outlet 532; the drive assembly 54 is disposed on the fixed base 52 and connects the lifting bracket 51 and the air inlet slide plate 40. It is understood that when the drive assembly 54 drives the lifting bracket 51 to open the first air vent 531 and the second air vent 532, it can simultaneously drive the air inlet slide plate 40 to slide to the first position, that is, the lower air vent 42 of the slide plate is connected to the lower air vent 35 of the hood, and the upper air vent 41 of the slide plate is blocked by the guide rib 37; when the drive assembly 54 drives the lifting bracket 51 to close the first air vent 531 and the second air vent 532, it can simultaneously drive the air inlet slide plate 40 to slide to the second position, that is, the upper air vent 41 of the slide plate is connected to the upper air vent 33 of the hood, and the lower air vent 42 of the slide plate is blocked by the guide rib 37. Since the first air vent 531 is connected to the second air vent 532, when the lifting bracket 51 closes the first air vent 531 and the second air vent 532, the indoor air outlet 12 can be connected to the exhaust duct 521 through the second air vent 532 and the first air vent 531, thereby forming a complete exhaust path.

[0066] Specifically, please refer to [the relevant document] again. Figure 2 and Figure 3In this embodiment, the drive assembly 54 includes a drive member 541, a gear 542, a lifting rack 543, and a sliding rack 544; the drive member 541 is disposed on the fixed base 52, and the gear 542 is disposed on the output shaft of the drive member 541; the lifting rack 543 is connected to the lifting bracket 51 and meshes with the gear 542; the sliding rack 544 is connected to the air intake sliding plate 40 and meshes with the gear 542; wherein, the drive member 541 drives the gear 542 to rotate, causing the lifting rack 543 and the sliding rack 544 to move away from each other in the vertical direction. It is understood that the lifting rack 543 and the sliding plate rack 544 are arranged opposite to and parallel to each other. When the gear 542 rotates, the lifting rack 543 and the sliding plate rack 544 move upward and downward respectively, thereby driving the lifting bracket 51 and the air intake sliding plate 40 to move upward and downward respectively. Through a set of gears 542, the lifting bracket 51 and the air intake sliding plate 40 are simultaneously driven to achieve the switching of air intake and exhaust paths.

[0067] Specifically, please refer to [the relevant document] again. Figure 1 In this embodiment, a slide plate pivot 43 is provided on the side wall of the air inlet slide plate 40, and a sliding clearance groove 38 is provided on the air inlet shroud 30. The slide plate pivot 43 passes through the sliding clearance groove 38 and is connected to the slide plate rack 544. It can be understood that when the slide plate rack 544 moves up and down, it drives the air inlet slide plate 40 to move via the slide plate pivot 43. By providing the slide plate pivot 43 and the sliding clearance groove 38, the sliding trajectory of the air inlet slide plate 40 can be restricted, while simultaneously reducing the sealing gap.

[0068] Furthermore, please refer again. Figure 2 and Figure 3 In this embodiment, the fixed base 52 is provided with a groove 522, and a sealing cover 523 is provided on the groove 522. The gear 542, the lifting rack 543, and the sliding rack 544 are all disposed in the groove 522. The sealing cover 523 has a rotating shaft hole 5231. The driving member 541 is fixed to the side of the sealing cover 523 away from the groove 522, and the output shaft of the driving member 541 passes through the rotating shaft hole 5231 and connects to the gear 542. It can be understood that the sealing cover 523 and the groove 522 cooperate to form an assembly cavity, and the gear 542, the lifting rack 543, and the sliding rack 544 are all disposed in the assembly cavity. The sealing cover 523 and the groove 522 provide isolation and protection for the gear 542, the lifting rack 543, and the sliding rack 544, preventing external foreign objects from affecting the gear 542, the lifting rack 543, and the sliding rack 544.

[0069] Specifically, please refer to [the relevant document] again. Figure 2 and Figure 3 In this embodiment, the groove 522 has a first clearance groove 5221 on the groove wall corresponding to the sealing cover 523, and the sealing cover 523 has a first guide rail 5232 on the side corresponding to the groove 522; the slide rack 544 has a first guide groove 5441 on the side near the sealing cover 523, the first guide groove 5441 cooperates with the first guide rail 5232, the slide rack 544 has a first connecting arm 5442 on the side opposite to the gear 542, the first connecting arm 5442 has a guide groove 5443, and the slide shaft 43 passes through the sliding clearance groove 38 and the first clearance groove 5221 and connects with the guide groove 5443. It can be understood that the first guide rail 5232 cooperates with the first guide groove 5441 to limit the movement of the slide rack 544, and the guide groove 5443 on the first connecting arm 5442 and the slide shaft 43 on the air intake slide 40 form a motion assembly guide. The guide groove 5443 and the first clearance groove 5221 are both arc-shaped grooves. Since the slide plate rack 544 moves in a straight line, the guide groove 5443 and the first clearance groove 5221 are designed as arc-shaped grooves to adapt to the arc-shaped movement of the air intake slide plate 40.

[0070] Specifically, please refer to [the relevant document] again. Figure 2 and Figure 3 In this embodiment, a second clearance groove 5222 is further provided on the groove wall of the sealing cover 523 corresponding to the groove 522. A second guide rail 5233 is also provided on the side of the sealing cover 523 corresponding to the groove 522. A second guide groove 5431 is provided on the side of the lifting rack 543 near the sealing cover 523. The second guide groove 5431 cooperates with the second guide rail 5233. A second connecting arm 5432 is provided on the side of the lifting rack 543 away from the sealing cover 523. The second connecting arm 5432 passes through the second clearance groove 5222 and connects to the lifting bracket 51. It can be understood that the second guide groove 5431 and the second guide rail 5233 cooperate to form a motion assembly guide for the lifting rack 543. When the lifting rack 543 slides up and down on the second guide rail 5233, it drives the lifting bracket 51 to move up and down through the second connecting arm 5432.

[0071] Furthermore, please refer again. Figure 2 and Figure 3In this embodiment, a light strip 533 is also provided around the first air vent 531 and the second air vent 532 on the lifting base 53. When the lifting bracket 51 is raised and the first air vent 531 and the second air vent 532 are opened, the light strip 533 lights up, and the fresh air module 100 activates the fresh air function. The lighting of the light strip 533 indicates the activation of the fresh air function and also has a certain aesthetic effect.

[0072] Furthermore, please refer again. Figure 1 In this embodiment, the fresh air module 100 further includes a filter support 60 and a filter (not shown) disposed on the filter support 60. The connection between the volute 10 and the air inlet hood 30 defines a fourth chamber 13, which communicates with the first chamber 11 and the second chamber 31. The filter support 60 is inserted into the fourth chamber 13. It is understood that when the fresh air module 100 introduces fresh air, outdoor fresh air enters the second chamber 31 through the lower air vent 35 of the hood, then passes through the filter in the fourth chamber 13, and finally exits through the first chamber 11 from the indoor air outlet 12.
