[0075] Optionally, as Figure 6As shown, the fresh air pipe 90 further comprises an insulation layer 922, which is sleeved on the outer side of the second pipeline 92.

The lower position of the drain pipe 953 and the thick copper pipe 951 facilitates the natural discharge of condensate water and the efficient transmission of refrigerant, ensuring the stable operation of the system. This layered arrangement not only fully utilizes the vertical space, but also simplifies the pipeline layout, facilitating installation and maintenance, and facilitating the circulation of refrigerant, water and fresh air.

[0099] Optionally, the pipeline assembly further comprises a foam 96, which is arranged in the gap between the drain pipe 953, the thick copper pipe 951, the thin copper pipe 952 and the first pipeline 91. The foam 96 can effectively fill the gap between the pipeline assemblies, reduce vibration transmission and noise generation, and improve the quietness of the system. At the same time, the foam 96 has good heat preservation performance, which can prevent the refrigerant pipe and the drain pipe 953 from causing energy loss or condensate water icing due to temperature changes, and improve the energy efficiency and reliability of the system.

[0102] Optionally, the pipeline assembly further comprises a waterproof seal arranged between the integrated pipeline 95 and the inner wall surface of the reserved hole 11, and / or arranged between the first pipeline 91 and the inner wall surface of the reserved hole 11. In the embodiment of the present disclosure, the waterproof seal is arranged outside the integrated pipeline 95 or the first pipeline 91, so that the waterproof seal can prevent the refrigerant pipe and the drain pipe 953 from causing energy loss or condensate water icing due to temperature changes, thereby improving the energy efficiency and reliability of the system. Moreover, the waterproof seal can effectively prevent moisture, dust or other foreign matter from entering the inside of the pipeline through the reserved hole 11, thereby avoiding corrosion or pollution of the pipeline assembly and prolonging the service life of the system. At the same time, the waterproof seal can also enhance the connection stability between the pipeline assembly and the reserved hole 11, reduce looseness or displacement caused by vibration or external impact, and ensure long-term stable operation of the pipeline assembly. In addition, the waterproof seal can also improve the sound insulation performance of the pipeline assembly, reduce noise leakage, and improve the use environment.

[0103] Optionally, the center of the thin copper pipe 952 is on one side of the center of the first pipeline 91, so that the height direction size occupied by the pipeline assembly can be reduced, so that multiple pipelines can be more reasonably arranged in the reserved hole 11.

[0104] Optionally, the equivalent circular tube diameter of the first pipeline 91 is greater than or equal to 37 mm.

[0105] The equivalent circular tube diameter refers to the diameter of a circular pipe having the same flow characteristics as the cross-sectional area of a non-circular pipe or channel. In the embodiment of the present disclosure, the diameter of the traditional fresh air pipe 90 is generally between 30-33 mm, and the equivalent circular tube diameter of the first pipeline 91 is greater than or equal to 37 mm, so that compared with the traditional fresh air pipe 90, the flow area of the fresh air pipe 90 of the embodiment of the present disclosure is larger, which can improve the air volume of the fresh air pipe 90, and further improve the air volume of the air treatment equipment. The fresh air pipe 90 of the embodiment of the present disclosure is arranged in an elliptical shape, which can increase the flow area inside the pipeline without increasing the size, thereby reducing the resistance and improving the air volume.

[0106] Optionally, the length of the minor axis of the first pipeline 91 is greater than or equal to 30.5 mm; and / or the length of the major axis of the first pipeline 91 is greater than or equal to 55.3 mm.

[0107] In this embodiment, the diameter of the reserved hole 11 is generally 63mm, and the first pipe 91 is elliptical with a length greater than or equal to 55.3mm. This ensures the flow area of ​​the first pipe 91, the fresh air flow of the fresh air pipe 90, and thus the air volume.

[0117] In the embodiments of the present disclosure, the new air outlet pipe 702 has a small diameter, and the new air outlet pipe 702 is connected to the turbid air outlet 105 through screw rotation, so that the new air outlet pipe 702 is conveniently connected to and detached from the turbid air outlet 105, and no additional connecting member is needed, thereby improving the convenience of installation and detachment.

[0118] Alternatively, the other end of the second pipeline 92 is connected to the inner wall of the turbid air outlet 105 through screw connection.

[0119] Alternatively, as shown in the drawings, Figure 13 The new air pipe 90 includes a new air inlet pipe 701, the new air inlet pipe 701 is connected to the new air inlet 101, and the air treatment device further includes a connecting pipeline 703, one end of the connecting pipeline 703 is connected to the new air outlet pipe 702 through screw connection, and the other end of the connecting pipeline 703 is detachably connected to the new air inlet 101.

[0120] In the embodiments of the present disclosure, the diameter of the new air inlet pipe 701 is larger than the diameter of the new air outlet pipe 702, so that the air volume of the new air inlet pipe 701 is large, and therefore, the new air inlet pipe 701 is connected to the new air inlet 101 through the connecting pipeline 703, so that the connection stability of the new air inlet pipe 701 is improved, and the new air inlet pipe 701 is prevented from deviating, bending or separating from the new air inlet 101 due to the influence of air flow.

[0121] Alternatively, the other end of the connecting pipeline 703 is connected to the new air inlet 101 through clamping.

[0122] Alternatively, the other end of the connecting pipeline 703 is arranged outside the new air inlet 101, the outer wall of the pipe wall of the new air inlet 101 is provided with a limiting column 704, the other end of the connecting pipeline 703 is provided with a limiting groove 705, when the connecting pipeline 703 is connected to the new air inlet 101, the limiting column 704 is located in the limiting groove 705, and the limiting column 704 abuts against the groove wall on one side of the limiting groove 705, so as to limit the rotation of the connecting pipeline relative to the new air inlet 101 in a preset direction.

[0123] Alternatively, the opening area of the limiting groove 705 is larger than the cross-sectional area of the limiting column 704, so that when the new air inlet pipe 701 needs to be detached, the new air inlet pipe 701 is rotated in a direction opposite to the preset direction, and the limiting groove 705 and the limiting column 704 are no longer in contact, so that the new air inlet pipe is conveniently detached from the device body.

[0125] Optionally, the second pipe 92 of the fresh air intake duct 701 can be sleeved on the outside of the fresh air inlet 101. Here, since the second pipe 92 is made of flexible material, the second pipe 92 can be tightly attached to the outside of the duct wall of the fresh air inlet 101.

[0126] Optionally, such as Figures 10 to 12 As shown, the housing 10 defines a first airflow channel having a fresh air inlet 101, a first indoor outlet 102, and a first stale air inlet 103; a first fan 201 is located in the first airflow channel, the inlet of the first fan 201 is connected to the fresh air inlet 101 and / or the first stale air inlet 103, and the outlet of the first fan 201 is connected to the first indoor outlet 102; a first purification device 203 is disposed in the first airflow channel for purifying the airflow flowing into the fresh air inlet 101 and / or the first stale air inlet 103.

[0127] In this embodiment, the first fan 201 drives outdoor airflow into the first airflow channel and then into the room through the first indoor outlet 102, providing fresh air to the room. The first fan 201 also drives indoor airflow into the first airflow channel from the first stale air inlet 103, and after purification through the first airflow channel, it flows into the room through the first indoor outlet 102. Thus, the air handling equipment, by setting up the first airflow channel and the first purification device 203, can effectively distinguish between fresh air and stale indoor air. Fresh air flows in from the fresh air inlet 101, passes through the first airflow channel, and is purified by the first purification device 203 before being sent into the room through the first indoor outlet 102. This provides fresh air to the room while also purifying impurities, ensuring indoor air quality. Stale indoor air flows in from the first stale air inlet 103, is purified by the first purification device 203, and then returned to the room through the first indoor outlet 102. This separation process significantly improves the air purification effect, ensuring continuous optimization of indoor air quality.

[0128] The inlet of the first fan 201 is connected to the fresh air inlet 101 and / or the first stale air inlet 103, allowing the device to flexibly switch between fresh air mode and internal circulation mode according to actual needs. In fresh air mode, the device introduces fresh outdoor air; in internal circulation mode, the device purifies indoor air. This flexible airflow control method can meet the air handling needs of different scenarios. Through reasonable design of airflow channels and fan layout, the air handling equipment can effectively reduce energy consumption during operation. At the same time, the first purification device 203 has a long service life, reducing the cost and resource waste of frequent filter replacements, making it more energy-efficient and environmentally friendly.

[0129] In addition, the fresh air inlet 101, the first dirty air inlet 103 and the first indoor outlet 102 of the shell 10 are integrated in the same air flow channel, which is compact in structure, easy to install and space layout. Moreover, the first purification device 203 and the fan are modularly designed, which is convenient for disassembly and maintenance, and prolongs the service life of the device.

[0130] Optionally, the first purification device 203 is a high-efficiency filter. For example, the first purification device 203 can be a HEPA filter, activated carbon adsorption, etc.

[0131] In the embodiment of the present disclosure, the first purification device 203 is arranged in the first air flow channel, which is used to purify the indoor dirty air flowing from the first dirty air inlet 103 and / or the fresh air flowing from the fresh air inlet 101. Through multi-layer filtration or high-efficiency purification technology, the particulate matter, odor and harmful substances in the air can be effectively removed, and the cleanliness of the indoor air is further improved.

[0132] Optionally, as shown in Figure 15 The air treatment equipment further comprises an anti-backflow plate 30 and an internal purification plate 40. The anti-backflow plate 30 is movably arranged at the fresh air inlet 101, which is used to open or close the fresh air inlet 101. The internal purification plate 40 is movably arranged at the first dirty air inlet 103, which is used to open or close the first dirty air inlet 103. When the anti-backflow plate 30 opens the fresh air inlet 101 and the internal purification plate 40 closes the first dirty air inlet 103, the first fan 201 drives the fresh air flowing from the fresh air inlet 101 to flow through the first air flow channel and then flows out from the first indoor outlet 102 to the indoor. When the anti-backflow plate 30 closes the fresh air inlet 101 and the internal purification plate 40 opens the first dirty air inlet 103, the first fan 201 drives the indoor air to flow from the first dirty air inlet 103 into the first air flow channel and then flows out from the first indoor outlet 102 to the indoor after being purified by the first purification device 203.

[0133] In the embodiments of the present disclosure, the anti-backflow plate 30 is movably arranged at the fresh air inlet 101 and can open or close the fresh air inlet 101 as needed. When the outdoor air quality is poor (such as haze, dust, etc.), the anti-backflow plate 30 closes the fresh air inlet 101, effectively preventing outdoor pollutants from flowing back into the indoor environment, and ensuring the cleanliness of the indoor air. This design significantly enhances the environmental adaptability of the air treatment device, especially in heavily polluted areas. The inner purification plate 40 is movably arranged at the first turbid air inlet 103 and can open or close the first turbid air inlet 103 as needed. When the anti-backflow plate 30 closes the fresh air inlet 101 and the inner purification plate 40 opens the first turbid air inlet 103, the device enters the internal circulation mode, and the first fan 201 drives indoor air to flow from the first turbid air inlet 103, purifies it through the first purification device 203, and then sends it back to the indoor environment through the first indoor outlet 102. This mode can efficiently purify indoor air and is suitable for scenarios where outdoor air quality is poor or rapid improvement of indoor air quality is needed. Through the coordinated work of the anti-backflow plate 30 and the inner purification plate 40, the air purification device can flexibly switch between the fresh air mode and the internal circulation mode according to actual needs. In the fresh air mode, the anti-backflow plate 30 opens the fresh air inlet 101, and the inner purification plate 40 closes the first turbid air inlet 103, and the device introduces outdoor fresh air; in the internal circulation mode, the anti-backflow plate 30 closes the fresh air inlet 101, and the inner purification plate 40 opens the first turbid air inlet 103, and the device purifies the indoor air in a circulating manner. This flexible mode switching function can meet the air treatment needs in different scenarios and improve user experience.

[0134] In addition, the design of the anti-backflow plate 30 and the inner purification plate 40 enables the air purification device to automatically select the optimal operating mode according to the indoor and outdoor air quality, avoiding unnecessary energy consumption. For example, when the outdoor air quality is good, the fresh air mode is preferred; when the outdoor air quality is poor, the internal circulation mode is automatically switched to, reducing the introduction of outdoor pollutants and reducing energy consumption. Moreover, the anti-backflow plate 30 and the inner purification plate 40 are designed to be movable, simple in structure and easy to realize automatic control. Through motor-driven or manual adjustment, the opening and closing states of the fresh air inlet 101 and the first turbid air inlet 103 can be quickly and accurately controlled, ensuring efficient operation of the device. By adding the anti-backflow plate 30 and the inner purification plate 40, the air treatment device of the present disclosure not only has the functions of anti-backflow and internal circulation purification, but also realizes flexible air flow mode switching and energy-efficient operation, significantly improving the practicality, environmental adaptability and user experience of the device.

[0135] Optionally, as Figure 12As shown, the shell 10 further defines a second airflow channel having a second turbid air inlet and a turbid air outlet 105, the turbid air outlet 105 being in communication with the outdoor, and the air treatment device further comprises a second fan 202 located in the containing cavity, the second fan 202 being in communication between the second turbid air inlet and the turbid air outlet 105; the second fan 202 can drive the indoor airflow to flow into the second airflow channel from the second turbid air inlet and then flow out from the turbid air outlet 105.

[0136] In the embodiments of the present disclosure, the second airflow channel is used to treat the turbid air in the room, and the second fan 202 can drive the turbid air in the room to flow into the second airflow channel through the second turbid air inlet and then be discharged to the outdoor from the turbid air outlet 105, so as to achieve the exhaust of the room. This independent airflow channel design avoids the mixing of turbid air and fresh air, ensures the cleanliness of indoor air, and reduces the pollution to the outdoor environment. Through the turbid air discharge function of the second airflow channel, the device can quickly discharge the polluted air in the room, avoiding the accumulation of pollutants in the room. By setting the second airflow channel and the second fan 202, the air treatment mode of the air treatment device is further increased, the fresh air in the first airflow channel flows into the room to supplement the fresh air, and the second airflow channel can discharge the turbid air to the outdoor, thereby improving the airflow circulation between the indoor and outdoor and quickly improving the air quality in the room. When the first airflow channel circulates, the airflow flowing into the room through the first turbid air inlet 103 flows into the room through the first purification device 203, and the airflow of the second airflow channel can discharge the air to the outdoor, also improving the air quality in the room.

[0137] Optionally, the air treatment device further comprises a second purification device 204 arranged in the second airflow channel and used for purifying the airflow flowing into the second turbid air inlet, and the second fan 202 can drive the indoor airflow to flow into the second airflow channel from the second turbid air inlet and then flow out from the turbid air outlet 105 after being purified by the second purification device 204.

[0138] In the embodiments of the present disclosure, the second airflow channel is used to treat the turbid air in the room, and the second fan 202 can drive the turbid air in the room to flow into the second airflow channel through the second turbid air inlet and then be discharged to the outdoor from the turbid air outlet 105 after being purified by the second purification device 204, so as to achieve the exhaust of the room. The purification function of the second purification device 204 further improves the cleanliness of the indoor air, providing a more healthy and comfortable air environment for the user. By setting the second airflow channel, the second fan 202 and the second purification device 204, the air treatment mode of the air treatment device is further increased, the fresh air in the first airflow channel flows into the room to supplement the fresh air, and the second airflow channel can discharge the turbid air to the outdoor, thereby improving the airflow circulation between the indoor and outdoor and quickly improving the air quality in the room.

[0139] Optionally, as shown in FIG. 6, the air treatment device further comprises a third airflow channel 301, the third airflow channel 301 being arranged in the containing cavity and having a third turbid air inlet 303 and a third turbid air outlet 305, the third turbid air outlet 305 being in communication with the outdoor, and the air treatment device further comprises a third fan 302 located in the containing cavity, the third fan 302 being in communication between the third turbid air inlet 303 and the third turbid air outlet 305; the third fan 302 can drive the indoor airflow to flow into the third airflow channel from the third turbid air inlet 303 and then flow out from the third turbid air outlet 305. Figure 11As shown, the shell 10 is also provided with a second indoor outlet 104, which is in communication with the second airflow passage. The air handling device further comprises an air duct switching plate movably arranged in the second airflow passage, which is used to adjust the communication between the outlet of the second fan 202 and the turbid air outlet 105 or the second indoor outlet 104, so that the airflow flowing into the second turbid air inlet is guided to flow from the turbid air outlet 105 to the outdoor or to flow through the second indoor outlet 104 to the indoor.

[0140] In the embodiments of the present disclosure, the air duct switching plate is movably arranged in the second airflow passage, which can adjust the communication between the outlet of the second fan 202 and the turbid air outlet 105 or the second indoor outlet 104 according to actual needs. When the air duct switching plate communicates the outlet of the second fan 202 with the turbid air outlet 105, the air handling device enters the turbid air discharge mode, and the indoor turbid air is discharged to the outdoor after being purified. When the air duct switching plate communicates the outlet of the second fan 202 with the second indoor outlet 104, the air handling device enters the internal circulation mode, and the purified airflow is sent back to the indoor. This flexible mode switching function can meet the air handling needs in different scenarios, improve the practicality of the device, and improve the air handling efficiency and energy utilization rate. Moreover, through the arrangement of the air duct switching plate, the communication between the outlet of the second fan 202 and the turbid air outlet 105 or the second indoor outlet 104 can be flexibly adjusted, the airflow direction can be controlled and adjusted, and the flexibility and diversity of air handling are improved, thereby improving the air handling efficiency. Through the design of the air duct switching plate, the second airflow passage can not only discharge turbid air, but also send the purified airflow back to the indoor. This dual-function integration enables the device to realize the dual effects of turbid air discharge and internal circulation purification in a single structure, thereby saving space and cost. Moreover, the air duct switching plate enables the air handling device to automatically select the optimal operation mode according to the indoor and outdoor air quality. For example, when the outdoor air quality is poor, the air handling device can be switched to the internal circulation mode to avoid the introduction of outdoor pollutants; when the indoor air quality is poor, the air handling device can be switched to the turbid air discharge mode to quickly discharge the indoor dirty air. This intelligent operation mode not only improves the air handling efficiency, but also reduces the energy consumption, and is more energy-saving and environmentally friendly.
