Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a two-way fresh air structure and an air conditioner. Background Technology

[0002] A fresh air conditioner is an air conditioner that introduces fresh outdoor air into a room to improve the indoor air environment. However, in related technologies, fresh air conditioners suffer from problems such as air turbulence and cross-contamination during ventilation, and therefore cannot fully meet the needs of users. Utility Model Content

[0003] This application provides a two-way fresh air structure and air conditioner, which can avoid air turbulence and cross-contamination, and better meet the needs of use.

[0004] On one hand, this application provides a bidirectional fresh air structure, including: an inner cylinder with a fresh air inlet, a fresh air cavity, and a fresh air outlet connected in sequence; and an outer cylinder sleeved outside the inner cylinder to form a stale air cavity between the outer cylinder and the inner cylinder. The outer cylinder has a stale air return port and a stale air exhaust port at its two ends, which are respectively connected to the stale air cavity. The fresh air inlet and the fresh air outlet are located outside the outer cylinder, and the stale air exhaust port and the fresh air inlet face opposite directions.

[0005] In some embodiments, the outer cylinder is provided with a clearance opening, and the fresh air outlet extends to the outside of the outer cylinder after passing through the clearance opening.

[0006] In some embodiments, the inner cylinder includes an inner cylinder body and a fresh air hood connected in sequence. The inner cylinder body is provided with the fresh air cavity and the fresh air outlet. The inner cylinder body is embedded in the outer cylinder to form the stale air cavity together with the outer cylinder. The fresh air hood is at least partially disposed outside the outer cylinder, and the fresh air inlet is formed on the fresh air hood.

[0007] In some embodiments, the outer cylinder includes an outer cylinder body and an exhaust hood connected in sequence. The outer cylinder body is sleeved outside the inner cylinder to form the sludge chamber with the inner cylinder. The sludge return air port is formed on the outer cylinder body at one end away from the exhaust hood, and the sludge exhaust air port is formed on the exhaust hood.

[0008] In some embodiments, one end of the inner cylinder where the fresh air inlet is located extends to the end of the exhaust hood away from the outer cylinder, so that the waste air exhaust port and the fresh air inlet are arranged sequentially along the length of the outer cylinder.

[0009] In some embodiments, the bidirectional fresh air structure includes a fresh air fan blade and a stale air fan blade, wherein the fresh air fan blade is disposed within the fresh air cavity and the stale air fan blade is disposed within the stale air cavity.

[0010] In some embodiments, the bidirectional fresh air structure includes a drive member, which drives the fresh air fan blade and the waste air fan blade to rotate synchronously.

[0011] In some embodiments, the driving component is a dual-output shaft motor, with a first output shaft and a second output shaft respectively at both ends. The first output shaft is fixedly connected to the fresh air fan blade, and the second output shaft is fixedly connected to the sludge fan blade.

[0012] In some embodiments, the driving component is a single-output shaft motor, and the fresh air fan blade and the waste air fan blade are connected in series on the output shaft of the single-output shaft motor.

[0013] On the other hand, this application provides an air conditioner that includes the bidirectional fresh air structure described in any of the above embodiments.

[0014] This embodiment of the application sets up an inner cylinder and an outer cylinder, forming a fresh air cavity and a stale air cavity on the inner and outer sides of the inner cylinder, respectively. This allows for the simultaneous use of the stale air cavity to exhaust indoor stale air to the outside and the fresh air cavity to draw outdoor fresh air into the room. The stale air exhaust port and the fresh air inlet are arranged in opposite directions to completely separate the stale air exhaust area and the fresh air intake area. This avoids the exhaust of indoor stale air from causing turbulence and pollution to the air in the fresh air intake area, ensuring the normal operation of the ventilation function and better meeting the usage requirements.

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. 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.

[0027] like Figure 1 and Figure 2 As shown, on the one hand, this application provides a bidirectional fresh air structure 1, which includes an inner cylinder 10 and an outer cylinder 20. It can simultaneously exhaust indoor stale air to the outside and draw in outdoor fresh air into the room. During ventilation, it can avoid air turbulence and cross-contamination, and better meet the needs of use.

[0028] The inner cylinder 10 is provided with a fresh air inlet 11, a fresh air cavity 12, and a fresh air outlet 13, which are connected in sequence. The outer cylinder 20 is sleeved outside the inner cylinder 10 to form a sludge cavity 21 between the outer cylinder 20 and the inner cylinder 10. The outer cylinder 20 is provided with a sludge return air inlet 22 and a sludge exhaust air inlet 23 at both ends, which are connected to the sludge cavity 21.

[0029] Here, the fresh air inlet 11 and the stale air outlet 23 are located outdoors, while the fresh air outlet 13 and the stale air return outlet 22 are located indoors. Outdoor fresh air can enter the fresh air chamber 12 through the fresh air inlet 11 and then be discharged into the indoor environment through the fresh air outlet 13, achieving the purpose of drawing outdoor fresh air into the room. Indoor stale air can enter the stale air chamber 21 through the stale air return outlet 22 and then be discharged outdoors through the stale air outlet 23, achieving the purpose of expelling indoor stale air to the outside. In this way, indoor stale air can be discharged outdoors and outdoor fresh air can be drawn into the room simultaneously.

[0030] The fresh air inlet 11 and fresh air outlet 13 are located outside the outer casing 20, while the stale air outlet 23 and fresh air inlet 11 face opposite directions. When simultaneously exhausting indoor stale air to the outside and drawing in outdoor fresh air, the indoor stale air can be exhausted from the stale air outlet 23 to one radial side of the bidirectional fresh air structure 1, while the fresh air inlet 11 can draw in outdoor fresh air from the other radial side of the bidirectional fresh air structure 1. This ensures that the stale air exhaust area and the fresh air intake area do not overlap and are staggered, thereby preventing the exhausted indoor stale air from causing turbulence and pollution to the air in the fresh air intake area, ensuring normal ventilation, and better meeting usage needs.

[0031] like Figures 1 to 3 As shown, in some embodiments, the outer cylinder 20 may be provided with a clearance opening 24, which penetrates the side wall of the outer cylinder 20. The fresh air outlet 13 extends to the outside of the outer cylinder 20 after passing through the clearance opening 24, so that the fresh air in the fresh air chamber 12 can be discharged into the room through the fresh air outlet 13. Here, the clearance opening 24 may be provided at the end of the outer cylinder 20 where the stale air return air outlet 22 is provided, so that the fresh air outlet 13 and the stale air return air outlet 22 are provided at the same end and can both be located in the room.

[0032] The structure of the inner cylinder 10 can be determined according to actual needs, and can adopt an integral structure or a split assembly structure. This application embodiment does not limit this. In some embodiments, the inner cylinder 10 may include an inner cylinder body 101 and a fresh air hood 102 connected in sequence. The inner cylinder body 101 is provided with a fresh air cavity 12 and a fresh air outlet 13. The inner cylinder body 101 is embedded in the outer cylinder 20 to form a polluted air cavity 21 with the outer cylinder 20. The fresh air hood 102 is at least partially disposed outside the outer cylinder 20, and the fresh air inlet 11 is formed on the fresh air hood 102.

[0033] The structure of the outer cylinder 20 can be determined according to actual needs, and can be an integral structure or a split assembly structure. This application embodiment does not limit this. In some embodiments, the outer cylinder 20 may include an outer cylinder body 201 and an exhaust hood 202 connected in sequence. The outer cylinder body 201 is sleeved outside the inner cylinder 10 to form a sludge chamber 21 with the inner cylinder 10. A sludge return air port 22 is formed on the outer cylinder body 201 at the end away from the exhaust hood 202, and a sludge exhaust air port 23 is formed on the exhaust hood 202.

[0034] In some examples, the end of the inner cylinder 10 with a fresh air inlet 11 can extend to the end of the exhaust hood 202 away from the outer cylinder 201. The fresh air inlet 11 and the stale air exhaust outlet 23 can be arranged sequentially along the length of the outer cylinder 20, so that the fresh air inlet 11 and the stale air exhaust outlet 23 are staggered along the length of the outer cylinder 20, further ensuring that the stale air exhaust area and the fresh air intake area are completely separated, thereby avoiding the exhaust of indoor stale air from causing turbulence and pollution to the air in the fresh air intake area, ensuring that the ventilation function is properly realized, and better meeting the usage needs.

[0035] In some embodiments, the bidirectional fresh air structure 1 may include a fresh air fan blade 30 and a stale air fan blade 40. The fresh air fan blade 30 is disposed within the fresh air chamber 12 and is used to provide suction pressure to draw fresh outdoor air into the room. The stale air fan blade 40 is disposed within the stale air chamber 21 and is used to provide exhaust pressure to exhaust stale indoor air to the outside.

[0036] In some examples, the bidirectional fresh air structure 1 may include a drive element 50. The drive element 50 drives the fresh air fan blade 30 and the waste air fan blade 40 to rotate synchronously. By setting a single drive element 50 to synchronously drive the fresh air fan blade 30 and the waste air fan blade 40, the number of drive elements 50 and the space required by the drive elements 50 can be saved, improving the compactness and small size of the bidirectional fresh air structure 1.

[0037] For example, the drive unit 50 can be a dual-output shaft motor. The dual-output shaft motor has a first output shaft and a second output shaft at its two ends, respectively. The first output shaft is fixedly connected to the fresh air fan blade 30, and the second output shaft is fixedly connected to the waste air fan blade 40. In this way, the drive unit 50 can stably drive the fresh air fan blade 30 and the waste air fan blade 40 to rotate synchronously.

[0038] like Figure 4 As shown, and exemplarily, the drive unit 50 is a single-shaft motor, and the fresh air fan blade 30 and the waste air fan blade 40 are connected in series on the output shaft of the single-shaft motor. In this way, the drive unit 50 can also stably drive the fresh air fan blade 30 and the waste air fan blade 40 to rotate synchronously.

[0039] like Figures 1 to 4 As shown, on the other hand, this application embodiment provides an air conditioner that includes the bidirectional fresh air structure 1 of any of the above embodiments. The type of air conditioner can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling-mounted unit, etc., and this application embodiment does not limit this. The air conditioner provided by this application embodiment has the above-mentioned bidirectional fresh air structure 1, which can simultaneously exhaust indoor stale air to the outside and draw in outdoor fresh air into the room, avoiding air turbulence and cross-contamination during ventilation, and better meeting the usage needs.

[0040] The bidirectional fresh air structure and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
