Description

TECHNICAL FIELD

[0001] The present application relates to a fresh air assembly, and also relates to a fresh air conditioner, and belongs to the technical field of air conditioning equipment. BACKGROUND

[0002] The main function of the fresh air conditioner is to introduce outdoor fresh air into the room to keep the indoor air fresh. However, in some cases, such as when there is a strong odor or a lot of smoke in the room, the effect of sending air into the room is poor, so the exhaust mode is added to the fresh air conditioner. However, both fresh air and exhaust air will have some impact on the temperature in the room, increasing power consumption, and in cases where the indoor air pollution is not high, it is not necessary to turn on the fresh air or exhaust mode, so an air purification mode is proposed to effectively solve this problem.

[0003] In Chinese Patent Application CN202222618698.6, a fresh air assembly and a fresh air conditioner are disclosed. A shunt plate is arranged in the air duct shell to form a fan inlet cavity connected to the return air inlet, and an air inlet cavity connected to the fresh air inlet and the exhaust air inlet. Then the connection air inlet, the exhaust air inlet, the return air inlet and the outlet are opened or closed by starting the fan module, the first air valve assembly and the second air valve assembly. To achieve switching between the fresh air mode, the internal circulation mode and the exhaust mode of the fresh air assembly. By arranging a flow guide grid in the exhaust air cavity, when the fresh air assembly is in the exhaust mode, the large high-speed airflow in the exhaust air cavity will flow through the flow guide grid, the flow guide grid will separate the large high-speed airflow into multiple small low-speed airflows, which will then be discharged to the outside through the fresh air inlet. Reducing the number of turbulent flows in the air inlet cavity and reducing the airflow speed, thereby increasing the exhaust capacity of the fresh air assembly and reducing the operating noise.

[0004] However, the existing technology has a complex air path with many bends, which affects the air volume and noise. SUMMARY

[0050] Specifically, the right outer shell 11, the middle outer shell 12, and the left outer shell 13 are connected sequentially from right to left to form the overall shell of the fresh air assembly, which contains various components of the fresh air assembly.

[0051] The first damper 21 is located at the opening 111 of the right outer casing 11 and can move left and right.

[0054] Figure 4 An exploded view of the HEPA filter assembly 5 of a fresh air system provided in an embodiment of the present invention. Figure 5 for Figure 4 A schematic diagram of the three-dimensional structure of the HEPA filter. Figure 6 for Figure 5 A three-dimensional structural diagram of the rotating shaft of the HEPA filter. Figure 7 for Figure 4 A three-dimensional structural diagram of the HEPA filter motor. (See diagram below.) Figures 4-6 As shown, the HEPA filter assembly 5 includes a HEPA filter bracket 51, a HEPA filter 52, a HEPA filter rotating shaft 53, a HEPA filter motor 54, a HEPA filter cover plate 55, a HEPA filter rotating shaft screw 56, and a bracket fixing nut 57. The HEPA filter bracket 51 has an elongated hole 511 for inserting the HEPA filter rotating shaft 53. The bracket fixing nut is screwed into the left end of the HEPA filter rotating shaft, and the HEPA filter rotating shaft screw is inserted into the elongated hole of the HEPA filter rotating shaft. The HEPA filter is aligned with the HEPA filter bracket. The HEPA filter cover plate is fitted onto one side of the assembled HEPA filter and HEPA filter bracket, making the HEPA filter and HEPA filter bracket a single unit. The HEPA filter motor is connected to the HEPA filter rotating shaft, causing the HEPA filter motor to drive the HEPA filter to rotate.

[0055] The mounting process of the HEPA net assembly 5 is described in detail below.

[0056] First, the HEPA net rotating shaft 53 is inserted into the long hole 511 of the HEPA net support 51.

[0057] Then, the support fixing nut 57 is screwed into the left end of the HEPA net rotating shaft 53, and the HEPA net rotating shaft screw 56 is inserted into the long hole 511 of the HEPA net rotating shaft 53, thereby fixing the HEPA net rotating shaft 53 and the HEPA net support 51, so that the HEPA net rotating shaft 53 rotates together with the HEPA net support.

[0058] Subsequently, the HEPA net 52 is arranged on the HEPA net support 51 in alignment, and the HEPA net cover plate 55 is sleeved on one side edge of the HEPA net 52 and the HEPA net support 51 that are closed together, so that the HEPA net 52 and the HEPA net support 51 are integrated.

[0059] Finally, the HEPA net motor 54 is connected with the HEPA net rotating shaft 53, so that the HEPA net motor 54 drives the HEPA net 52 to rotate.

[0060] The working principles of the fresh air assembly in three different modes provided by the embodiment of the present application are described in detail below with reference to the drawings.

[0061] For the convenience of description, the three modes are referred to as a fresh air mode M1, an exhaust air mode M2 and an air purification mode M3. The air directions in each mode are indicated by M1, M2 and M3 in the drawings.

[0062] Figure 8 The structure and working principle of the fresh air assembly provided by the embodiment of the present application in the fresh air mode are shown in the schematic diagram.

[0063] As shown in Figure 8 , the structure of the fresh air assembly provided by the embodiment of the present application in the fresh air mode is as follows.

[0064] The first air door 21 is located at the first position, so that the opening of the right shell 11 becomes the first air port A1. The first position refers to that the first air door 21 is located at the left half of the opening of the right shell 11, leaving the right half opening.

[0065] The second air door 22 is located at the second position, and the HEPA net assembly 5 is inclined to the left with the HEPA net rotating shaft as the center. The second position refers to that the second air door 22 is located in the right shell 11, thereby blocking the communication from the lower part of the right shell 11 to the upper part.

[0066] The third air door 23 is located at a third position, so that the middle shell 11 is communicated with the adapter 6. The input port 62 of the adapter 6 forms the second air port A2. The third position refers to that the third air door 23 is located in front of the middle shell 11.

[0067] Therefore, the fresh air assembly with the above structure, in operation, the external air (the dashed line represented by M1 in the figure) first enters the middle shell 12 through the second air port A2, then enters the right shell 11 through the HEPA net assembly 5, and finally enters the room through the first air port A1. Here, the air from the outside is filtered by the HEPA net assembly 5, and the external air is purified.

[0068] Figure 9 The structure and working principle of the fresh air assembly in the air exhaust mode provided by the embodiment of the present application are shown in the figure.

[0069] As Figure 9 shown, the structure of the fresh air assembly in the air exhaust mode provided by the embodiment of the present application is as follows.

[0070] The first air door 21 is located at a fourth position, so that the opening of the right shell 11 becomes the third air port A3. The fourth position refers to that the first air door 21 is located at the right half of the opening of the right shell 11, leaving the left half open.

[0071] The second air door 22 is located at a fifth position, and the HEPA net assembly 5 is tilted to the left around the HEPA net rotating shaft. The fifth position refers to that the second air door 22 is located in the middle shell 12, so that the right shell 11 is communicated with the lower part of the middle shell 12.

[0072] The third air door 23 is located at a third position, so that the middle shell 11 is communicated with the adapter 6. The input port 62 of the adapter 6 forms the second air port A2. The third position refers to that the third air door 23 is located in front of the middle shell 11.

[0073] Therefore, the fresh air assembly with the above structure, in operation, the external air (the dashed line represented by M1 in the figure) first enters the middle shell 12 through the second air port A2, then enters the right shell 11 through the HEPA net assembly 5, and finally enters the room through the first air port A1. Here, the air from the outside is filtered by the HEPA net assembly 5, and the external air is purified.

[0074] Figure 10 The structure and working principle of the fresh air assembly in the air exhaust mode provided by the embodiment of the present application are shown in the figure.

[0075] As Figure 10As shown, the fresh air assembly provided by the embodiment of the present application has the following structure in the air purification mode.

[0076] The first damper 21 is located at the fourth position, so that the opening of the right shell 11 becomes the third air outlet A3. The fourth position refers to that the first damper 21 is located at the right half of the opening of the right shell 11, leaving the left half open.

[0077] The second damper 22 is located at the fifth position, and the HEPA net assembly 5 is tilted to the right around the HEPA net rotation axis. The fifth position refers to that the second damper 22 is located in the middle shell 12, so that the right shell 11 is communicated with the lower part of the middle shell 12.

[0078] The third damper 23 is located at the sixth position, so that the middle shell 11 is closed with the adapter 6, and the fourth air outlet A4 is formed at the lower part of the middle shell. The sixth position refers to that the third damper 23 is located at the rear half of the lower part of the middle shell 11, so that the front half of the middle shell 12 is open.

[0079] Therefore, the fresh air assembly with the above structure, in operation, the indoor air (represented by the dashed line M3 in the figure) first enters the middle shell 12 through the third air outlet A3, and then enters the right shell 11 through the HEPA net assembly 5. At this time, the right shell 11 is communicated with the lower part of the middle shell 12, so that the air is discharged to the fourth air outlet A4 through the lower part of the middle shell 12. Since the fourth air outlet A4 is communicated with the indoor, the indoor air entering from the third air outlet A3 is returned to the indoor through the purification process of the fresh air assembly.

[0080] In addition, the embodiment of the present application also provides an air conditioner comprising the above fresh air assembly.

[0081] In summary, the present application achieves the switching between the fresh air mode, the exhaust air mode and the air purification mode by designing the rotatable HEPA net assembly 5 and the plurality of dampers, and controlling the positions of the HEPA net assembly 5 and the plurality of dampers. Moreover, the air duct structure of the present application is simple, thereby improving the flow amount of the air in the air duct.

[0082] It should be noted that the various embodiments in the present application can be combined to form new embodiments, all within the scope of the present application.

[0083] It should be noted that the "forming" referred to in the present application means that it can be obtained by using one of a plurality of processes, and is not limited to the processes listed in the embodiments.

[0084] It should be understood that the terms "upper", "lower", "left", "right", and the like refer to the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0085] In addition, the terms "first", "second", are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0086] The above has been described in detail. Any obvious modification made to it by those skilled in the art without departing from the essential content of the present application will constitute an infringement of the patent right of the present application and will bear the corresponding legal responsibility.
