[0024] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0026] The embodiment of the present application provides a fresh air duct assembly to solve the technical problem in the prior art that the fresh air duct cannot simultaneously take in fresh air and exhaust sewage air. The assembly will be described below in conjunction with the accompanying drawings.

[0027] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the fresh air duct assembly includes a fresh air duct 10 and a driving member 30. A partition 20 is provided in the fresh air duct 10, and the partition 20 is arranged along the extension direction of the fresh air duct 10 to divide the fresh air duct 10 into a fresh air channel 11 and an exhaust channel 12; a first blade 40 is provided at one end of the driving member 30, and a second blade 50 is provided at the other end of the driving member 30; the first blade 40 is arranged in the fresh air channel 11 to drive the outdoor air flow from the fresh air channel 11 to flow into the room; the second blade 50 is arranged in the exhaust channel 12 to drive the indoor air flow from the exhaust channel 12 to flow to the outdoors.

[0028] It should be noted that in the related art, the fresh air module is designed with a fresh air duct, which introduces outdoor fresh air and exhausts indoor dirty air respectively through the forward and reverse rotation of the motor. Since the fresh air duct cannot introduce fresh air and exhaust dirty air at the same time, when the fresh air module is in the fresh air intake mode, fresh air continuously enters the room, resulting in a positive pressure state in the room, and the indoor cold air will leak out through the door gap, etc., resulting in a waste of cooling capacity; and when the fresh air module is in the exhaust air mode, the room is in a negative pressure state, which will increase the speed at which outdoor hot air enters the room through the door gap, etc., and increase energy consumption.

[0029] To this end, the fresh air duct assembly provided in the present application divides the fresh air duct 10 into a fresh air channel 11 and an exhaust channel 12 by setting a partition 20, and a first blade 40 is set in the fresh air channel 11, and a second blade 50 is set in the exhaust channel 12. When the driving member 30 rotates, the first blade 40 drives the outdoor air flow from the fresh air channel 11 to the indoor, and the second blade 50 drives the indoor air flow from the exhaust channel 12 to the outdoors, so that the fresh air duct 10 can discharge indoor polluted air while introducing outdoor fresh air, which is beneficial to ensure consistent indoor air pressure, avoid air leakage from door gaps and the like when the indoor pressure is positive, causing waste of cooling, or avoid outdoor air entering the indoor through door gaps and the like when the indoor pressure is negative, causing increased energy consumption.

[0030] It is understandable that a through-wall hole is usually reserved on the wall, and a part of the fresh air duct 10 extends to the outside through the through-wall hole, so that one end of the fresh air duct 10 is located indoors, and the other end of the fresh air duct 10 is located outdoors, thereby realizing indoor and outdoor gas exchange. In the present application, only one fresh air duct 10 is needed to simultaneously realize fresh air intake and sewage exhaust, and there is no need to separately set up a fresh air duct and an exhaust duct, which is conducive to reducing the number of through-wall holes and reducing the installation cost of the fresh air duct assembly.

[0031] In this embodiment, the outer diameter of the fresh air duct 10 is matched with the inner diameter of the through-wall hole, so that the fresh air duct 10 can be installed in the through-wall hole. Specifically, the through-wall hole and the fresh air duct 10 are both circular, and the outer diameter of the fresh air duct 10 is slightly smaller than the aperture of the through-wall hole, so as to increase the amount of fresh air entering the room as much as possible. When the through-wall hole is elliptical or other shapes, the shape and size of the fresh air duct 10 can be adjusted accordingly in this embodiment, so that the fresh air duct 10 is matched with the through-wall hole, thereby making full use of the space of the through-wall hole to increase the air intake and exhaust volume of the fresh air duct 10.

[0032] Optionally, in one embodiment, see Figure 1 and Figure 3The driving member 30 is a double-shaft motor, the first blade 40 is connected to the first output shaft 31 of the driving member 30, the second blade 50 is connected to the second output shaft 32 of the driving member 30, and the first output shaft 31 and the second output shaft 32 rotate synchronously. It can be understood that by setting a double-shaft motor, one motor can be used to drive the first blade 40 and the second blade 50 to rotate at the same time, so that the fresh air duct 10 can discharge indoor polluted air while introducing outdoor fresh air, which is conducive to simplifying the structure of the fresh air duct assembly and reducing the cost of the fresh air duct assembly.

[0033] For further information, see Figure 1 and Figure 2 , the fresh air duct 10 has a bending section 13, the partition 20 includes a bending plate 21 corresponding to the bending section 13, and the driving member 30 is installed on the bending plate 21 so that the first output shaft 31 and the second output shaft 32 both extend along the length direction of the fresh air duct 10. In this embodiment, the first blade 40 and the second blade 50 can both be axial flow blades. Through the setting of the bending plate 21, it is possible to provide an installation position for the driving member 30, and ensure that after the driving member 30 is installed, its first output shaft 31 can be located in the fresh air channel 11, and the second output shaft 32 can be located in the exhaust air duct. At the same time, the first output shaft 31 and the second output shaft 32 both extend along the length direction of the fresh air duct 10, so that the axial flow blade can achieve air suction and exhaust along the length direction of the fresh air duct 10, improve the efficiency of the fresh air intake and sewage exhaust of the fresh air duct 10, and ensure that the first blade 40 and the second blade 50 will not collide with the partition 20 and the inner wall of the fresh air duct 10 during rotation.

[0034] Optionally, in one embodiment, see Figure 1 and Figure 2 The fresh air duct 10 includes a first straight pipe section 14 and a second straight pipe section 15 , one end of the bent section 13 is sealedly connected to the first straight pipe section 14 , and the other end of the bent section 13 is sealedly connected to the second straight pipe section 15 .

[0035] Specifically, the inner wall and the outer wall of the bending section 13 are both curved, the first straight pipe section 14 and one end of the bending section 13 are connected by a circular arc transition, and the second straight pipe section 15 and the other end of the bending section 13 are connected by a circular arc transition. When indoor polluted air and outdoor fresh air pass through the bending section 13, the curved inner wall can reduce friction and reduce the noise caused by the airflow hitting the inner wall of the fresh air duct 10.

[0036] In addition, in this embodiment, the fresh air duct 10 can be integrally injection molded to make the connection between the first straight pipe section 14, the bent section 13 and the second straight pipe section 15 more stable, thereby improving the structural strength of the fresh air duct 10.

[0037] Optionally, in one embodiment, see Figure 1 and Figure 4The partition 20 includes a first plate body 22 and a second plate body 23. The first plate body 22 is arranged in the first straight pipe section 14 and connected to one end of the bent plate 21. The second plate body 23 is arranged in the second straight pipe section 15 and connected to the other end of the bent plate 21.

[0038] Specifically, the first plate body 22, the second plate body 23 and the bent plate 21 are all flat plates. The first plate body 22 extends along the length direction of the first straight pipe section 14, and the second plate body 23 extends along the length direction of the second straight pipe section 15. The plane where the first plate body 22 is located is parallel to the plane where the second plate body 23 is located. The bent plate 21 is obliquely arranged between the first plate body 22 and the second plate body 23 and is sealed and connected to the first plate body 22 and the second plate body 23 respectively to prevent air from blowing through the fresh air channel 11 and the exhaust air channel 12, and to ensure that the overall extension direction of the partition 20 is consistent with the fresh air duct 10.

[0039] Optionally, in one embodiment, the hardness of the bent section 13 is less than the hardness of the first straight section 14 and the second straight section 15. It is understandable that by reducing the hardness of the bent section 13, the impact of the airflow on the inner wall of the bent section 13 can be appropriately weakened, thereby further reducing the noise in the fresh air duct 10.

[0040] Specifically, the material of the fresh air duct 10 may be PVC (polyvinyl chloride) material, and the hardness of the bent section 13 may be made smaller than the hardness of the first straight section 14 and the second straight section 15 by causing the bent section 13 to undergo physical or chemical changes. For example, in the processing of the fresh air duct 10, a plasticizer is added to the bent section 13 to reduce the intermolecular forces, reduce the polymer viscosity, and thus enhance the flexibility of the bent section 13, or the bent section 13 is subjected to thermoforming processing to soften the bent section 13. Of course, the inner wall of the bent section 13 may be set thinner relative to the first straight section 14 and the second straight section 15, so as to achieve a lower hardness of the bent section 13 than the first straight section 14 and the second straight section 15. The processing method for reducing the hardness of the bent section 13 may be selected according to actual needs, such as production cost, processing difficulty, etc., and this application does not impose any restrictions on this.

[0041] Optionally, in one embodiment, see Figure 1 The partition 20 is arranged on the axis of the fresh air duct 10 so that the cross-sectional areas of the fresh air passage 11 and the exhaust air passage 12 are the same. It can be understood that the partition 20 is arranged on the axis of the fresh air duct 10 so that the volume of the fresh air duct and the volume of the exhaust air duct are consistent, thereby achieving the consistency of the air intake and exhaust volumes of the fresh air duct 10, ensuring the stability of the indoor pressure, and improving the user experience.

[0042] Optionally, in one embodiment, the partition 20 is made of a heat-insulating material. Since the fresh air duct 10 is divided into two mutually non-interfering areas by the partition 20, the partition 20 made of the heat-insulating material can isolate the heat exchange between the two areas, that is, isolate the heat exchange between the fresh air channel 11 and the exhaust channel 12.

[0043] An embodiment of the present application also provides an air conditioner, which includes a fresh air duct assembly. The specific structure of the fresh air duct assembly refers to the above-mentioned embodiment. Since the air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0044] Optionally, in one embodiment, see Figure 5 The air conditioner includes a condenser 60, and the outlet of the exhaust passage 12 is arranged toward the condenser 60. It can be understood that the exhaust passage 12 is used to exhaust indoor dirty air. When the air conditioner is cooling, the indoor air is cold air with a lower temperature. In this embodiment, by arranging the outlet of the exhaust passage 12 toward the outdoor condenser 60, the indoor cold air can be fully utilized to dissipate heat from the condenser 60, which is beneficial to increasing the cooling capacity of the air conditioner and reducing the energy consumption of the air conditioner.
