[0050] Reference below Figure 1-Figure 15 An air conditioner 100 according to an embodiment of the present invention is described.

[0051] like Figure 1-Figure 15As shown, the air conditioner 100 according to an embodiment of the present invention includes: an air conditioning indoor unit (not shown in the figure) and a fresh air device 10, the fresh air device 10 is arranged in the air conditioning indoor unit, and the fresh air device 10 has a fresh air channel (not shown in the figure), a fresh air inlet 101 and a fresh air outlet 102, the fresh air inlet 101 includes a first air inlet 1011 and a second air inlet 1012, the first air inlet 1011, the second air inlet 1012 and the fresh air outlet 102 are all connected to the fresh air channel, the outside air can enter the fresh air channel through the first air inlet 1011 and the second air inlet 1012 respectively, and the air in the fresh air channel flows out through the fresh air outlet 102, which can increase the air supply of the fresh air device 10.

[0052] Among them, the fresh air inlet 101 can be connected to the outdoor space, and the fresh air outlet 102 can be connected to the indoor space, so that outdoor fresh air can enter the fresh air channel through the fresh air inlet 101, and the air entering the fresh air channel can enter the room through the fresh air outlet 102, so as to realize the function of the air conditioner 100 to transport fresh air to the room.

[0053] The air conditioner 100 according to the embodiment of the present invention is compared with the air conditioner with a fresh air function in the related art. By arranging the first air inlet 1011 and the second air inlet 1012 on the fresh air device 10, and the first air inlet 1011 and the second air inlet 1012 are connected to the fresh air outlet 102 through the fresh air channel, the outside air can enter the fresh air channel through the first air inlet 1011 and the second air inlet 1012 respectively, which is equivalent to increasing the number of fresh air inlets and greatly increasing the total air inlet area of ​​the fresh air, thereby reducing the resistance of the outside air entering the fresh air channel through a single fresh air inlet, thereby increasing the air supply of the fresh air device 10, and reducing the working noise of the fresh air device 10, thereby improving the user's comfort.

[0054] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the air conditioner 100 further includes: a first duct 20 and a second duct 30, one end of the first duct 20 (such as Figure 3 The front end shown in FIG. 1 is connected to the first air inlet 1011, and the other end of the first conduit 20 (as shown in FIG. Figure 3 The rear end shown in FIG. 1 can be connected to the outdoor space, so that outdoor air can enter the fresh air channel through the first conduit 20; one end of the second conduit 30 (as shown in FIG. 1 ) can be connected to the outdoor space, so that outdoor air can enter the fresh air channel through the first conduit 20; Figure 3 The front end shown in FIG. 1 is connected to the second air inlet 1012, and the other end of the second duct 30 (as shown in FIG. Figure 3 The rear end as shown can be connected to the outdoor space, so that outdoor air can enter the fresh air channel through the second duct 30.

[0055] For example, the other end of the first conduit 20 and the other end of the second conduit 30 may pass through the wall to communicate with the outdoor space.

[0056] Among them, the first duct 20 and the second duct 30 can cooperate with each other to improve the utilization rate of the installation space. Within the limited installation space, the cross-sectional area of ​​the first duct 20 and the second duct 30 can be increased, the air inlet area of ​​the fresh air device 10 can be increased, and the resistance to air flow can be reduced, which is beneficial to increase the air supply volume of the fresh air device 10, realize the air supply function of the air conditioner 100, and improve the fresh air supply effect of the air conditioner 100.

[0057] In addition, by providing at least two air inlets, each of which is provided with a duct, the constraints of the installation space on the duct can be reduced, and the resistance of outdoor air flowing in the duct can be reduced, while facilitating the installation and arrangement of the duct.

[0058] In some examples, the number of air inlets can be more, for example, the number of air inlets can be three, and each air inlet corresponds to a duct to connect the air inlet with the outdoor space, which can further increase the air inlet area of ​​the fresh air device 10, reduce the resistance to air flow, and further improve the fresh air supply effect of the air conditioner 100.

[0059] In some examples, the cross-sectional shapes of the first conduit 20 and the second conduit 30 are both irregular. For example, the cross-sectional shapes of the first conduit 20 and the second conduit 30 may be irregular circular rings. In this embodiment, a concave cavity is formed on the outer surface of one of the first conduit 20 and the second conduit 30, and a portion of the other of the first conduit 20 and the second conduit 30 is located in the concave cavity.

[0060] Compared with a duct with a regular circular ring shape (for example, a circle) in cross-section, the technical solution of the present application can improve the utilization rate of the installation space. Within a limited installation space, the cross-sectional area of ​​the first duct 20 and the second duct 30 can be increased, thereby increasing the air intake of the fresh air device 10. At the same time, the tube wall of the special-shaped duct has multiple streamlined designs, which can reduce the probability of turbulence when the air flows in the duct, thereby reducing the overall resistance coefficient of the duct, and part of the inner wall surface of the special-shaped duct can bulge outward or be recessed inward, which can guide the air flow and reduce the probability of airflow separation flow, thereby reducing wind resistance.

[0061] Of course, the cross-sectional shapes of the first conduit 20 and the second conduit 30 can be regular shapes, such as square, circular or triangular, etc., which is easy to process and can reduce production costs.

[0062] like Figure 3 As shown, in some examples, the air conditioner indoor unit includes a base 50, and the base 50 has a drain port 501, and the drain port 501 can be used to drain condensed water in the air conditioner indoor unit.

[0063] The air conditioner 100 further includes a third conduit 40, one end of which (eg Figure 4 The front end shown in FIG. 4 is connected to the drain port 501, and the other end of the third conduit 40 (as shown in FIG. Figure 4 The left end of the air inlet 1011 is connected to the first duct 20, and then the condensed water in the air-conditioning indoor unit can flow into the first duct 20 through the third duct 40, and be discharged to the outside through the first duct 20, so that the first air inlet 1011 can share the space of the first duct 20 with the third duct 40, that is, the first air inlet 1011 takes in air through the first duct 20, and the third duct 40 drains water through the first duct 20, which can save space and is conducive to the miniaturization of the air-conditioning indoor unit, and is convenient for the installation and arrangement of multiple ducts, which can reduce the constraints of the installation space on the position of the duct, and can reduce the number of bends in the duct, thereby reducing the resistance to air flow.

[0064] like Figure 3 and Figure 4 As shown, in some examples, the first conduit 20 includes a first pipe segment 21 and a second pipe segment 22, and one end of the first pipe segment 21 (such as Figure 4 The front end shown in FIG. 1 is connected to the first air inlet 1011, and one end of the second pipe section 22 (as shown in FIG. Figure 4 The rear end shown) can be connected to the outdoor space.

[0065] The air conditioner 100 further includes: a three-way connector 60, the three-way connector 60 having a first interface 611, a second interface 612 and a third interface 621, the first interface 611, the second interface 612 and the third interface 621 are interconnected, and the first interface 611 is connected to the other end of the first pipe section 21 (such as Figure 4 The second interface 612 is connected to the other end of the second pipe section 22 (as shown in FIG. Figure 4 The third interface 621 is connected to the other end of the third conduit 40 (as shown in FIG. Figure 4 The left end shown is connected.

[0066] Therefore, by setting the three-way joint 60, the first duct 20 and the third duct 40 are connected through the three-way joint 60, and then the first air inlet 1011 and the drain outlet 501 are connected to the outside through the second pipe section 22 of the first duct 20, which can make full use of the space of the first duct 20, which is conducive to shortening the length of the third duct 40, thereby achieving the effect of saving space and reducing costs.

[0067] like Figure 4 and Figure 6 As shown, in some examples, the three-way joint 60 includes a main pipe 61 , a branch pipe 62 , and a gas blocking member 63 .

[0068] The two ends of the main pipe 61 (such as Figure 4The front end and the rear end shown in the figure respectively define a first interface 611 and a second interface 612. For example, the first interface 611 can be located at the front end of the main pipe 61, and the second interface 612 can be located at the rear end of the main pipe 61, so as to facilitate the first pipe section 21 and the second pipe section 22 to be connected through the main pipe 61 to form a complete first conduit 20.

[0069] One end of the branch pipe 62 (such as Figure 4 The left end of the branch pipe 62 is connected to the middle of the main pipe 61, and the other end of the branch pipe 62 (as shown in Figure 4 The right end as shown in the figure defines a third interface 621 to facilitate the communication between the third conduit 40 and the first conduit 20 through the branch pipe 62.

[0070] The air blocking piece 63 is arranged in the main pipe 61, and a part of the air blocking piece 63 can be arranged opposite to the third interface 621, or the entire air blocking piece 63 can be arranged opposite to the third interface 621, which can increase the resistance of the air in the third duct 40 to flow to the first duct 20, and reduce the probability of the air in the air-conditioning indoor unit flowing back to the fresh air device 10 through the third duct 40 and the first duct 20, thereby reducing the probability of indoor air entering the fresh air device 10 and improving the fresh air supply effect of the fresh air device 10.

[0071] Among them, a flow port 603 can be defined between the air blocking piece 63 and the inner wall of the main pipe 61, and the flow port 603 is used to connect the second interface 612 and the third interface 621. The water in the third conduit 40 can flow to the second pipe section 22 of the first conduit 20 through the flow port 603. On the basis of reducing the probability of air from the air-conditioning indoor unit flowing back into the fresh air device 10, it is ensured that the first conduit 20 can drain normally, and condensed water can be prevented from flowing back into the fresh air device 10, thereby improving the user experience.

[0072] like Figure 6 As shown, in some examples, the gas blocking member 63 may be a gas blocking plate, and a portion of the branch pipe 62 is recessed outward, that is, a portion of the branch pipe 62 faces a direction away from the main pipe 61 (eg, Figure 6 The right side as shown is recessed so that a first flow cavity 601 is defined between the branch pipe 62 and the air blocking plate, and the first flow cavity 601 is used to connect the third interface 621 and the flow port 603.

[0073] In the above technical solution, the air blocking plate has a simple structure and can be used together with the branch pipe 62 to define a smaller flow port 603, thereby increasing the resistance of the fresh air in the first duct 20 to flow to the third duct 40 and reducing the probability of air from the air conditioner indoor unit flowing back into the fresh air device 10.

[0074] In addition, by setting up the first flow chamber 601, on the one hand, during the process of condensed water in the third duct 40 being discharged through the first duct 20, the condensed water flows to the first flow chamber 601 to achieve buffering, thereby reducing the probability of condensed water in the third duct 40 colliding with the air blocking plate and generating abnormal noise, thereby reducing the working noise of the fresh air device 10. On the other hand, the wall surface of the first flow chamber 601 can increase the resistance of the fresh air in the first duct 20 to flow to the third duct 40 through the flow port 603.

[0075] More specifically, one end of the branch pipe 62 close to the main pipe 61 (eg Figure 6 The left end as shown in the figure can form a bending structure. Such a configuration can increase the resistance of the air in the branch pipe 62 to flow toward the flow port 603, reduce the probability of indoor air flowing back to the first duct 20 through the third duct 40 and flowing into the fresh air device 10 through the first duct 20, and improve the fresh air supply effect of the fresh air device 10.

[0076] like Figure 8 As shown, in other examples, the gas blocking member 63 can be a gas blocking pipe, which is arranged in the main pipe 61, and a second flow cavity 602 is defined between the outer peripheral wall of the gas blocking pipe and the inner peripheral wall of the main pipe 61. The second flow cavity 602 is connected to the third interface 621 and the flow port 603, so that the condensed water in the third conduit 40 can be discharged through the first conduit 20, and the first conduit 20 can be completely isolated from the main pipe 61, that is, the flow port 603 is located at the end of the gas blocking pipe close to the outside of the room (such as Figure 8 The condensed water in the third duct 40 can be quickly discharged after entering the first duct 20 through the flow port 603, thereby preventing the indoor air from flowing back into the first duct 20 through the third duct 40 and flowing into the fresh air device 10 through the first duct 20, thereby improving the fresh air supply effect of the fresh air device 10.

[0077] In addition, by setting up the structure of the air blocking pipe, the second flow chamber 602 can be extended, and the condensed water flowing to the second flow chamber 602 can be buffered, reducing the probability of the condensed water in the third duct 40 colliding with the air blocking pipe and generating abnormal noise, thereby reducing the working noise of the fresh air device 10, and the flow rate of the water in the second flow chamber 602 can be slowed down, making the flow of condensed water smoother, so as to fill the entire second flow chamber 602 and prevent indoor air from passing through the flow port 603 along with the water flow.

[0078] like Fig.11 As shown, in some other examples, the air conditioner 100 further includes: an on-off device 70 , and the on-off device 70 is used to control the on-off between the first duct 20 and the third duct 40 .

[0079] When the fresh air device 10 is working, the on-off device 70 can control the first duct 20 to be disconnected from the third duct 40, thereby preventing indoor air from flowing back into the first duct 20 through the third duct 40 and flowing into the fresh air device 10 through the first duct 20, thereby improving the fresh air supply effect of the fresh air device 10.

[0080] After the fresh air device 10 stops working, the on-off device 70 can control the first duct 20 to be connected with the third duct 40, ensuring that the condensed water in the air conditioner indoor unit flows out smoothly through the third duct 40 and the first duct 20 in turn, thereby realizing the discharge of the condensed water.

[0081] like Fig.11 As shown, in some examples, the on-off device 70 includes: a valve plate 71 and a driving member 72, the driving member 72 is connected to the valve plate 71 to drive the valve plate 71 to rotate, and the valve plate 71 can control the on-off between the first conduit 20 and the third conduit 40 during the rotation process.

[0082] The valve plate 71 here can be arranged in the third conduit 40, and the valve plate 71 can rotate in the third conduit 40, and the driving member 72 is connected to the valve plate 71 to drive the valve plate 71 to rotate. In the specific example where the air conditioner 100 also includes a three-way connector 60, the valve plate 71 can be arranged in the branch pipe 62 connected to the third conduit 40. Of course, the valve plate 71 can also be directly arranged at the third interface 621 or at the connection position between the third conduit 40 and the branch pipe 62.

[0083] Among them, the driving member 72 can be a driving motor, and the output shaft of the driving motor is connected to the rotating shaft of the valve plate 71. When the output shaft of the driving motor rotates, it can drive the valve plate 71 to rotate, so that the third conduit 40 is connected or disconnected with the first conduit 20, and the degree of opening and closing of the valve can be controlled by controlling the rotation angle of the output shaft of the driving motor, which is conducive to controlling the discharge speed of condensed water.

[0084] Furthermore, the driving motor can control the valve to rotate to a certain angle, so that the condensed water can flow out through the first duct 20 when the fresh air device 10 is delivering fresh air, and the probability of indoor air flowing back to the fresh air device 10 through the third duct 40 and the first duct 20 can be reduced, thereby improving the fresh air delivery effect of the fresh air device 10 and achieving normal discharge of condensed water.

[0085] In some examples, the on-off device 70 can be a check valve, which is disposed in the third conduit 40. Condensed water can accumulate in the third conduit 40 and generate water pressure. The check valve can automatically open under the action of the water pressure, so that the condensed water in the third conduit 40 enters the first conduit 20 through the check valve. When the water pressure drops to a level that is not enough to push the check valve to open, that is, when the condensed water is completely discharged, the check valve can automatically close to prevent indoor air from flowing back into the fresh air device 10, and the operation is convenient.

[0086] Of course, the on-off device can also be a ball valve, which is arranged in the third duct 40, and the control structure for controlling the opening and closing of the ball valve is located outside the third duct 40. The operator can manually open the ball valve or open the ball valve in an electrically operated manner by setting a drive motor, which can improve the sealing of the third duct 40 and prevent indoor air from flowing back into the fresh air device 10.

[0087] like Figure 12-Figure 15 As shown, in some examples, the air conditioner indoor unit includes an indoor heat exchanger; the air conditioner 100 also includes: an air conditioner outdoor unit and a protective pipe 83, the air conditioner outdoor unit includes an outdoor heat exchanger and a compressor, the outdoor heat exchanger and the compressor are connected, and the outdoor heat exchanger is connected to the indoor heat exchanger through a first connecting pipe 81, and the compressor is connected to the indoor heat exchanger through a second connecting pipe 82. The compressor can compress the cooling medium to the outdoor heat exchanger, and the cooling medium of the outdoor heat exchanger can flow to the indoor heat exchanger through the first connecting pipe 81. After the cooling medium is heat exchanged in the indoor heat exchanger, it can flow to the compressor through the second connecting pipe 82 for circulation, so as to realize the indoor cooling or heating function.

[0088] Among them, the first connecting pipe 81, the second connecting pipe 82, the first conduit 20 and the second conduit 30 are all passed through the protective pipe 83, so that the two connecting pipes and the two conduits can be passed through the wall along with the protective pipe 83 to connect with the outdoor space, which can play a role in gathering multiple pipelines, facilitate installation and maintenance, and at the same time play a role in protecting multiple pipelines, thereby increasing service life and reducing maintenance costs.

[0089] In some examples, the parts of the first connecting pipe 81, the second connecting pipe 82, the first conduit 20 and the second conduit 30 that pass through the wall can be hard pipe structures. On the one hand, it is convenient for the installation and fixation of the protective pipe 83. On the other hand, it can improve the structural strength of the parts of the connecting pipes and the conduits that pass through the wall, reduce the probability of the connecting pipes and the conduits being damaged by being squeezed by the wall, and increase the service life. Among them, the two connecting pipes can be made of metal pipes such as steel pipes or aluminum pipes, which have a long service life.

[0090] like Fig.13 As shown, in some examples, the outer peripheral wall of the first duct 20 and the outer peripheral wall of the second duct 30 are fitted together, which can save space in the protective tube 83, help reduce the cross-sectional size of the protective tube 83, and facilitate the installation and fixation of the protective tube 83. At the same time, it can save wall space, which is beneficial to reduce the number of perforations opened in the wall by staff for installing the air conditioner 100.

[0091] The first connecting pipe 81 and the second connecting pipe 82 are respectively arranged on both sides of the center line of the first conduit 20 and the second conduit 30, which effectively utilizes the space between the protection pipe 83 and the two conduits, thereby improving the space utilization rate. In addition, since the temperatures of the cooling medium flowing in the first connecting pipe 81 and the second connecting pipe 82 are different, the probability of heat exchange between the first conduit 20 and the second conduit 30 can be reduced, which is beneficial to improving the indoor cooling effect or heating effect of the air conditioner 100.

[0092] like Fig.13 As shown, in some examples, the protective tube 83 is filled with a heat-insulating material 831, and the heat-insulating material 831 wraps the first connecting tube 81, the second connecting tube 82, the first conduit 20 and the second conduit 30, which can play a role in insulating the entire protective tube 83, preventing the multiple pipes in the protective tube 83 from exchanging heat with the outside world, thereby reducing energy loss, and at the same time, it can play a role in insulating the multiple pipes in the protective tube 83, preventing the multiple pipes from exchanging heat in the protective tube 83, and improving the working effect of the air conditioner 100.

[0093] In some examples, the insulation material 831 may be glass wool, which wraps the multiple pipes in the protective tube 83 to effectively maintain the internal temperature of the connecting pipes and the conduit and reduce energy loss. The insulation material 831 may also be polypropylene (PP) foam insulation material or polyethylene (PE) foam insulation material, which may improve the thermal insulation effect between the multiple pipes in the protective tube 83.

[0094] In some examples, the thermal insulation material 831 may be sleeved outside the protective tube 83 , and the thermal insulation material 831 may be a polyurethane (PU) foam tube, which may effectively reduce heat transfer and improve the thermal insulation effect of the multiple pipes in the protective tube 83 .

[0095] like Fig.13 As shown, in some examples, the outer side of the first connecting pipe 81 is provided with a first thermal insulation layer 811, and the outer side of the second connecting pipe 82 is provided with a second thermal insulation layer 821, which can improve the heat insulation effect of the first connecting pipe 81 and the second connecting pipe 82, and can further prevent the first connecting pipe 81 and the second connecting pipe 82 from respectively exchanging heat with the outside, thereby reducing energy loss and improving the heating or cooling effect of the air conditioner 100 on the indoor room.

[0096] In some examples, the first thermal insulation layer 811 and the second thermal insulation layer 821 may be polyurethane (PU) flexible foam tubes, which may effectively reduce heat transfer and improve the thermal insulation effect on the first connecting tube 81 and the second connecting tube 82 .

[0097] like Fig.15As shown, in other examples, both the first conduit 20 and the first connecting tube 81 can be fitted with the second conduit 30, and a heat-conducting structure 84 can be provided between the first conduit 20 and the second conduit 30, and a heat-conducting structure 84 can also be provided between the first connecting tube 81 and the second conduit 30, so that the first conduit 20 can exchange heat with the second conduit 30 through the heat-conducting structure 84, and the first connecting tube 81 can exchange heat with the second conduit 30 through the heat-conducting structure 84, and further, the first connecting tube 81 can exchange heat with the first conduit 20 through the heat-conducting structure 84.

[0098] In some other examples, both the first conduit 20 and the second connecting tube 82 can be fitted with the second conduit 30, and a heat-conducting structure 84 can be provided between the first conduit 20 and the second conduit 30, and a heat-conducting structure 84 can also be provided between the second connecting tube 82 and the second conduit 30, so that the first conduit 20 can exchange heat with the second conduit 30 through the heat-conducting structure 84, and the second connecting tube 82 can exchange heat with the second conduit 30 through the heat-conducting structure 84.

[0099] It should be noted that the temperature of the condensed water is relatively low. When the condensed water in the indoor unit of the air conditioner enters the first conduit 20 (water outlet pipe) through the third conduit 40, the condensed water can absorb heat to reduce the temperature of the first conduit 20, so that the temperature of the first conduit 20 can be lower than the outdoor ambient temperature. Then, the first conduit 20 exchanges heat with the second conduit 30 through the heat-conducting structure 84, so that the temperature of the second conduit 30 can be reduced. Therefore, when the air conditioner 100 cools the indoor room, when the outdoor air passes through the first conduit 20 and the second conduit 30 respectively, the air and the conduit wall surface conduct heat transfer by convection, which can cool the fresh air. The cooled fresh air enters the room, which can improve the comfort of the fresh air, improve the cooling effect on the indoor room, and is beneficial to reduce the power consumption of the air conditioner 100.

[0100] In addition, when the air conditioner 100 cools the indoor environment, the temperature of the first connecting pipe 81 is lower than the temperature of the outdoor air, and then the first connecting pipe 81 exchanges heat with the second conduit 30 through the heat-conducting structure 84, and at the same time, the second conduit 30 exchanges heat with the first conduit 20 through the heat-conducting structure 84, so that the temperature of the first conduit 20 and the second conduit 30 can be reduced. Therefore, when the outdoor air passes through the first conduit 20 and the second conduit 30 respectively, the air and the conduit wall surface perform convection heat transfer, which can cool the fresh air. The cooled fresh air enters the room, which can improve the comfort of the fresh air, improve the cooling effect on the room, and help reduce the power consumption of the air conditioner 100.

[0101] When the air conditioner 100 heats the room, the temperature of the first connecting pipe 81 is higher than the temperature of the outdoor air, and then the first connecting pipe 81 exchanges heat with the second conduit 30 through the heat-conducting structure 84, and at the same time, the second conduit 30 exchanges heat with the first conduit 20 through the heat-conducting structure 84, so that the temperature of the first conduit 20 and the second conduit 30 can be increased. Therefore, when the outdoor air passes through the first conduit 20 and the second conduit 30 respectively, the air and the conduit wall surface perform convection heat transfer, and the fresh air can be heated. The heated fresh air enters the room, which can improve the comfort of the fresh air, improve the heating effect of the room, and help reduce the power consumption of the air conditioner 100.

[0102] like Fig.15 As shown, in some examples, the heat-conducting structure 84 can be integrally formed with the second conduit 30, which can simplify the structure and facilitate operation; the heat-conducting structure 84 can be a metal heat conductor such as iron or aluminum, which has a good heat-conducting effect, and the heat-conducting structure 84 can be mounted outside the second conduit 30 after processing, which is convenient for loading and unloading and maintenance.

[0103] like Fig.15 As shown, in some examples, part of the heat-conducting structure 84 may be recessed toward the inside of the second conduit 30 to form an arc shape, so that the first conduit 20 and the heat-conducting structure 84 can be fitted together, and the first connecting tube 81 and the heat-conducting structure 84 can be fitted together, which can increase the contact area between the heat-conducting structure 84 and the first conduit 20, and can increase the contact area between the heat-conducting structure 84 and the first connecting tube 81, thereby improving the heat exchange effect between the first conduit 20, the first connecting tube 81 and the second conduit 30.

[0104] like Figure 1 and Figure 2 As shown, in some examples, the fresh air device 10 includes: a housing 11, a wind wheel, and a motor. The housing 11 defines a fresh air channel. The first air inlet 1011 and the second air inlet 1012 are arranged on the same side of the housing 11 (such as Figure 1 The rear side shown in the figure is beneficial to the installation and arrangement of multiple pipelines on the rear side of the shell 11, and can save space; the wind wheel is arranged in the fresh air channel, and the wind wheel can rotate in the fresh air channel, and the motor is connected to the wind wheel to drive the wind wheel to rotate, so that the motor drives the wind wheel to rotate, and the outdoor air can enter the room through the fresh air channel, thereby realizing the function of supplying fresh air to the room.

[0105] The fresh air device 10 may further include a filter element 12, which is disposed in the fresh air channel and between the fresh air inlet 101 and the fresh air outlet 102. The filter element 12 may be a filter net, which may effectively intercept dirt (such as dust) in the outdoor air, improve the cleanliness of the air, improve the fresh air delivery effect of the fresh air device 10, and improve the user experience.

[0106] Of course, the fresh air device 100 may also include a sterilization component and a humidification component to improve the air quality of the fresh air and further enhance the user's comfort.

[0107] Among them, the shell 11 includes a volute, and the wind wheel can be a centrifugal wind wheel. The rotation of the centrifugal wind wheel can allow the outside air to enter the fresh air channel through the fresh air inlet 101. The air in the fresh air channel flows through the centrifugal wind wheel and then flows out through the fresh air outlet 102. Among them, when the centrifugal wind wheel rotates, a low-pressure area will be generated at the center of the centrifugal wind wheel, which will attract the surrounding air to enter, and the blade movement of the centrifugal wind wheel will accelerate the air entering the area and change the flow direction of the air, so that the air flows along a curve, and due to the limitation of the volute shape, the air can be expanded, thereby increasing the air flow rate and the air supply volume of the fresh air device 10.

[0108] like Figure 1-Figure 6 As shown, in some specific examples, the air conditioner 100 includes: an air conditioner indoor unit, a fresh air device 10, a three-way joint 60, a first conduit 20, a second conduit 30 and a third conduit 40, the air conditioner indoor unit includes a base 50, the base has a drain port 501, and the drain port 501 is connected to one end of the third conduit 40 (such as Figure 3 The fresh air device 10 has a fresh air channel, a fresh air inlet 101 and a fresh air outlet 102. The fresh air inlet 101 includes a first air inlet 1011 and a second air inlet 1012. The first air inlet 1011 and the second air inlet 1012 are both connected to the fresh air outlet 102 through the fresh air channel. The first duct 20 includes a first pipe section 21 and a second pipe section 22. The first air inlet 1011 is connected to one end of the first pipe section 21 (as shown in FIG. Figure 3 The second air inlet 1012 is connected to one end of the second conduit 30 (as shown in FIG. Figure 3 The other end of the second conduit 30 (as shown in Figure 3 The rear end shown) is connected to the outdoor space.

[0109] The three-way joint 60 includes a main pipe 61, a branch pipe 62 and a gas blocking member 63. One end of the main pipe 61 (such as Figure 4 The front end shown in FIG. 1 defines a first interface 611, and the other end of the first pipe section 21 (as shown in FIG. Figure 4 The other end of the main pipe 61 (as shown in the rear end) is connected to the first interface 611; Figure 4 The rear end shown in FIG. 1 defines a second interface 612, and one end of the second pipe section 21 (as shown in FIG. Figure 4 The front end shown in FIG. 1 is connected to the second interface 612, and the other end of the second pipe section 21 (as shown in FIG. Figure 3 The rear end shown in FIG. 1 is connected to the outdoor space; one end of the branch pipe 62 (as shown in FIG. Figure 4 The left end of the branch pipe 62 is connected to the middle of the main pipe 61, and the other end of the branch pipe 62 (as shown in Figure 4 The third interface 621 is defined at the right end of the third conduit 40. Figure 3 The gas blocking member 63 is located in the three-way joint 60, and a flow port 603 can be defined between the gas blocking member 63 and the inner wall of the main pipe 61.

[0110] When the air conditioner 100 cools the indoor environment, condensed water is generated in the indoor unit of the air conditioner. The condensed water first enters the third duct 40 through the drain port 501, then enters the second pipe section 22 of the first duct 20 through the flow port 603 in the three-way joint 60, and finally flows out through the second pipe section 22 to discharge the condensed water. When the air conditioner 100 supplies fresh air to the indoor environment, the outdoor air first enters the fresh air channel through the first duct 20 and the second duct 30 respectively, and then enters the indoor environment through the fresh air outlet 102. At the same time, the air blocking member 63 in the three-way joint 60 can prevent the air in the third duct 30 from entering the first duct 20, thereby preventing the indoor air from flowing back into the fresh air device 10, thereby improving the fresh air supply effect of the air conditioner 100.
