[0030] like Figure 1-Figure 5 As shown, the present invention provides a fresh air duct assembly, comprising an outer tube 10 and at least one inner tube 20. The inner tubes 20 are disposed in the outer tube 10, and the gap between the inner tubes 20 and the outer tube 10 forms a first channel portion 101. The outer tube 10 is made of an elastic material so that the outer tube 10 can adaptively adjust the cross-sectional area of ​​the outer tube 10 according to the airflow pressure in the first channel portion 101.

[0031] It should be noted that the width of the outer tube 10 is greater than that of the inner tube 20 to ensure that there is still sufficient clearance to form the first channel portion 101 after the inner tube 20 is installed in the outer tube 10. When only one inner tube 20 is installed in the outer tube 10, the inner tube 20 serves as the fresh air intake duct 201, and the first channel portion 101 formed by the gap between the inner tube 20 and the outer tube serves as the exhaust gas discharge channel.

[0032] Among them, the outer tube 10 is made of an elastic material as a whole. The elastic material has high elasticity at room temperature and can undergo large deformation under the action of a small external force to expand and contract in accordance with the changes in the airflow pressure in the first channel portion 101. When the airflow pressure in the first channel portion 101 increases, the outer tube 10 can expand accordingly, increasing its cross-sectional area to increase the gap between the inner tube 20 and the outer tube 10, thereby increasing the flowable cross-sectional area of ​​the first channel portion 101.

[0033] It should be noted that when the airflow pressure in the first channel portion 101 is low, the outer tube 10 is in a natural state, i.e., it neither contracts nor expands. As the airflow pressure in the first channel portion 101 gradually increases, the outer tube 10 begins to expand accordingly. After the outer tube 10 expands, as the airflow pressure in the first channel portion 101 gradually decreases, the outer tube 10 begins to contract from the expanded state and returns to the natural state. In the above case, when the width of the outer tube 10 is greater than the width of the inner tube 20, the outer tube 10 is in the natural state.

[0034] According to the above description and explanation, it can be understood that in actual application, an inner tube 20 is connected to the fresh air module, and the inner tube 20 connected to the fresh air module is used to introduce fresh air; the first channel part 101 is connected to the exhaust fan of the air conditioner to discharge indoor waste. At the same time, the outer tube 10 is made of elastic material, so that the outer tube 10 can adaptively change the cross-sectional area of ​​the outer tube 10 according to the airflow pressure of the first channel, and then adjust the flowable area of ​​the first channel. For example, when the airflow pressure increases, the cross-sectional area of ​​the outer tube 10 increases accordingly, so that the flow rate of the first channel part 101 increases, so as to ensure the discharge efficiency of indoor waste and improve the ventilation efficiency of indoor gas.

[0035] In some embodiments, the elastic material can be one of a variety of elastic materials, such as styrene thermoplastic elastomer, styrene-butadiene rubber, and EPDM rubber. It should be noted that to ensure that the outer tube 10 can undergo significant deformation under relatively small external forces, the thickness of the outer tube 10 is thinner than that of conventional pipes. For example, the thickness of the outer tube 10 is 0.3-0.5 times that of the inner tube 20.

[0036] In some embodiments, in order to ensure that the outer tube 10 can undergo relatively obvious deformation under a relatively small external force, the tube wall of the outer tube 10 is configured to be wavy.

[0037] In some embodiments, the fresh air duct assembly further includes a support frame 30 , which is disposed in the outer tube 10 . The support frame 30 is disposed along the length direction of the outer tube 10 , and the inner tubes 20 are all disposed in the support frame 30 .

[0038] It is understandable that, since the outer tube 10 has a high elasticity, in order to prevent it from contracting excessively when subjected to other external forces and affecting the flowable area of ​​the first channel portion 101, a support frame 30 is provided to limit the contraction limit of the outer tube 10, thereby preventing the outer tube 10 from excessively contracting from its natural state under the action of other external forces.

[0039] It should be noted that the support frame 30 has the same length as the outer tube 10 and the inner tube 20, and wraps the inner tube 20. Generally, the support frame 30 is made of metal braiding.

[0040] In some embodiments, when the outer tube 10 is in a natural state, the inner wall of the outer tube 10 is in close contact with the support frame 30 .

[0041] It is understood that the support frame 30 is closely attached to the inner wall of the outer tube 10 when the outer tube 10 is in its natural state. This is so that when the outer tube 10 is in its natural state, there is space inside the support frame 30 to install more inner tubes 20. When one inner tube 20 is used to introduce fresh air, the remaining inner tubes 20 can be used for drainage and refrigerant transportation, respectively, to provide for the integration of the fresh air duct assembly.

[0042] In some embodiments, the support frame 30 is helical.

[0043] It is understandable that the spiral support frame 30 can support the outer tube 10 with minimal material cost, and at the same time has a certain flexibility so as to bend in conjunction with the outer tube 10 .

[0044] In some embodiments, the fresh air duct assembly further includes a connecting cable 300 , which is disposed in the support frame 30 .

[0045] It is understood that the connecting cable 300 is generally used to connect the indoor unit and the outdoor unit to transmit monitoring information, control information, and power, etc. The monitoring information can be the freshness of the outside air, the outside temperature and humidity, etc., and the control information can be used to control the start and stop of the outdoor unit, etc.

[0046] In some embodiments, the fresh air duct assembly includes at least three inner tubes 20 , which are a fresh air introduction tube 201 , a drainage tube 202 , and a refrigerant delivery tube 203 .

[0047] It can be understood that the fresh air inlet pipe 201, the drainage pipe 202 and the refrigerant delivery pipe 203 are all arranged in the support frame 30, and the gaps between the fresh air inlet pipe 201, the drainage pipe 202, the refrigerant delivery pipe 203 and the gaps between the three and the exterior constitute the first channel portion 101.

[0048] In some embodiments, the fresh air duct assembly further includes a connecting cable 300 , which is disposed in the outer tube 10 , and a gap between the connecting cable 300 , the inner tube 20 and the outer tube 10 forms a first channel portion 101 .

[0049] It is understandable that the support frame 30 is not provided inside the outer tube 10, and the connecting cable 300 and the inner tube 20 are directly provided inside the outer tube 10. For ease of management, the connecting cable 300 can be bundled into one piece and then bundled into one piece with any one of the inner tubes 20 in the outer tube 10.

[0050] In some embodiments, the fresh air duct assembly includes a plurality of inner tubes 20 , which are bundled together into one.

[0051] It is also understandable that the plurality of inner tubes 20 are bound together into one body, and in the absence of the support frame 30 , the inner tubes 20 can be prevented from being scattered and affecting the airflow in the first channel portion 101 .

[0052] The present utility model also provides an air conditioner, including the fresh air duct assembly in the above-mentioned embodiment. Since the air conditioner includes the fresh air duct assembly of a combination of some or all of the above-mentioned embodiments, it has at least some or all of the beneficial effects of all the above-mentioned embodiments, which will not be described one by one here.

[0053] In some embodiments of the present invention, the air conditioner includes a fresh air module and an exhaust fan, and the at least one inner tube 20 in the fresh air duct assembly is a first inner tube 20. The first channel portion 101 is connected to the exhaust fan, and the first inner tube 20 is connected to the fresh air module.

[0054] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the application concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
