[0044] Referring to Figures 1 to 13 As shown, according to the embodiment of the present application, the fresh air component includes a housing, and a first drainage structure and a second drainage structure are provided on the housing. The first drainage structure drains the condensate water on the housing to the front side of the housing, and the second drainage structure drains the condensate water on the housing to the back side of the housing.

[0045] After condensate water appears, the fresh air component can timely collect the condensate water on the fresh air component through the first drainage structure and the second drainage structure, drain the condensate water on the fresh air component away, and then discharge it outside the air conditioner, avoiding the problem that excessive accumulation of condensate water in the air conditioner causes condensate water to drip, affecting the service life of the air conditioner and the fresh air quality. Since the condensate water can be timely drained out of the air conditioner and cannot cause a greater impact on the air conditioner, the heat insulation layer such as sponge for heat insulation to achieve the anti-condensation effect on the fresh air component can be reduced or omitted, and no additional components are required, which can reduce the assembly difficulty of the fresh air component and improve the production efficiency. In addition, by providing the first drainage structure and the second drainage structure with different drainage directions on the fresh air component, the condensate water generated by the fresh air component can be drained to different positions through different drainage structures, so that the condensate water can be drained nearby, reducing the flow path of the condensate water during the drainage process and improving the drainage efficiency of the condensate water.

[0046] In order to improve the drainage effect of the drainage structure on the condensed water of the fresh air component and minimize the adverse effects of the condensed water on the fresh air component, the first drainage structure and the second drainage structure should be distributed at the hot and cold air alternating positions of the fresh air component. The hot and cold air alternating positions of the fresh air component can be determined by simulating with thermodynamic software or obtained by those skilled in the art according to experience.

[0047] In one embodiment, the housing includes a volute 1 and a volute cover 2. The volute cover 2 is provided on one side of the volute 1. The first drainage structure is provided on the side of the volute 1 away from the volute cover 2. The generation of condensed water is mainly due to the hot and cold intersection of outdoor air and indoor air, and the hot and cold intersection of outdoor air and indoor air mainly concentrates on the outer surface of the housing. Therefore, the condensed water on the volute is mainly generated on the surface of the volute 1 in contact with the indoor air. Setting the first drainage structure on the side of the volute 1 away from the volute cover 2 can fully collect the condensed water generated on the volute 1 through the first drainage structure and quickly drain away the condensed water generated on the volute 1 by using the first drainage structure, thereby preventing excessive accumulation of condensed water on the volute 1.

[0048] In one embodiment, the first drainage structure includes a first water diversion rib 3 protruding from the surface of the volute 1. The drainage surface of the first water diversion rib 3 gradually decreases along the direction from the water inlet end to the water outlet end of the first drainage structure. The first water diversion rib 3 protruding from the surface of the volute 1 can block the condensed water generated on the surface of the volute 1, causing the condensed water to gather on the first water diversion rib 3. The drainage surface of the first water diversion rib 3 gradually decreases along the direction from the water inlet end to the water outlet end of the first drainage structure, which can form a drainage effect on the condensed water gathered on the first water diversion rib 3, enabling the condensed water to flow along the drainage effect of the first water diversion rib 3, thereby quickly guiding the condensed water generated on the volute 1 out of the fresh air component and preventing excessive accumulation of condensed water from causing adverse effects on the fresh air component.

[0049] In this embodiment, the first water diversion rib 3 is a plate structure, and the first water diversion rib 3 is hermetically connected to the volute 1 to prevent the condensed water from leaking at the connection position between the first water diversion rib 3 and the volute 1 and ensure the condensed water collection and drainage effects of the first drainage structure.

[0050] The height of the first water diversion rib 3 increases along the direction away from the connection surface of the volute 1, thereby preventing the condensed water from flowing out at the position of the first water diversion rib 3 away from the connection surface of the volute 1. After the condensed water reaches the drainage surface of the first water diversion rib 3, under the inclination of the drainage surface, it flows towards the inner side close to the volute 1, ensuring the collection effect of the first water diversion rib 3 on the condensed water. The drainage surface of the first water diversion rib 3 is not only higher on the outside and lower on the inside, but also decreases in height along the drainage direction of the condensed water, which can ensure the collection and diversion effects on the condensed water.

[0051] The first condensate guiding rib 3 can not only adopt a flat plate structure, but also an arc plate structure, so that the condensate will not flow out of the drainage surface of the first condensate guiding rib 3 due to the radian of the arc plate.

[0052] In one embodiment, the first condensate guiding rib 3 includes a confluence section 4, and the confluence section 4 is located at the guiding end of the first condensate guiding rib 3. The confluence end 4 can confluence the condensate drained by the first condensate guiding rib 3, so that the condensate can be gathered at a predetermined position and then discharged, which can improve the discharge effect of the condensate and at the same time improve the drainage capacity of the condensate. As a preferred embodiment, the confluence end 4 can be in a V shape or a U shape, preferably in a V shape, which can increase the side wall slope of the confluence end 4, accelerate the confluence speed of the condensate, and improve the discharge efficiency of the condensate.

[0053] In one embodiment, a first drain port 5 is provided on the lower side of the confluence section 4, and the first drain port 5 is located on the side of the bottom of the confluence section 4 away from the volute 1. The condensate gathered at the confluence section 4 can be discharged from the first drain port 5. The first drain port 5 is the rear section of the confluence section 4. After the condensate is gathered at the confluence section 4, it can further guide the condensate in the confluence section 4. At the same time, the flow state of the condensate at the confluence section 4 can be designed by using the first drain port 5 to avoid the direct outflow of the condensate at the confluence section 4, resulting in problems such as high-drop noise and easy splashing, which affect the use environment.

[0054] In one embodiment, along the direction away from the volute 1, the guiding surface of the confluence section 4 inclines downward, which can make the condensate on the confluence section 4 more effectively and thoroughly guided to the first drain port 5 and then discharged through the drain port 5, avoiding the phenomenon of condensate accumulation in the confluence section 4.

[0055] As a preferred embodiment, a confluence groove 6 is formed at the bottom of the confluence section 4, and the confluence groove 6 gradually inclines toward the side wall of the first drain port 5 along the direction close to the first drain port 5. In this embodiment, the condensate of the confluence section 4 will be gathered in the confluence groove 6 and then flow along the confluence groove 6. When the confluence groove 6 gradually inclines toward the side wall of the first drain port 5 along the direction close to the first drain port 5, the condensate flowing out of the confluence groove 6 will flow along the guiding of the confluence groove 6 to the side wall of the first drain port 5 and then flow along the side wall to the first drain port 5 and then be discharged from the first drain port 5. This structure uses the side wall of the first drain port 5 as the guiding wall for the flow of the condensate, which can make the condensate flow gently along the side wall, eliminate the flow drop of the condensate, and further reduce the flow noise of the condensate.

[0056] As another preferred embodiment, one side surface of the confluence section 4 is coplanar with one side surface of the first drain opening 5. In this embodiment, under the guiding action of the confluence groove 6, the condensed water will flow along the direction of the confluence groove 6 to one side surface of the first drain opening 5, then flow downward along this side surface to the first drain opening 5, and finally be discharged from the first drain opening 5. This structure makes the flow direction of the condensed water in the confluence groove 6 consistent with the extending direction of the side surface, so that the flow noise generated by the condensed water hitting this side surface can be basically eliminated.

[0057] The end of the confluence groove 6 intersects with one side side wall of the first drain opening 5, so that there is no gap between the end of the confluence groove 6 and this side side wall of the first drain opening 5. Therefore, the condensed water can flow more smoothly to this side side wall and flow to the bottom of the first drain opening 5 through this side side wall.

[0058] In one embodiment, drainage walls 7 are arranged on both sides of the outlet of the first drain opening 5. The drainage walls 7 can play a role in guiding the condensed water discharged from the first drain opening 5, so that the condensed water flows along the drainage walls 7 to a preset position instead of dripping directly from a high altitude. Therefore, the ticking noise generated during the dripping process of the condensed water can be eliminated.

[0059] In one embodiment, the second drainage structure includes a first drainage section 8. The first drainage section 8 is arranged on the volute 1 and extends from the outer peripheral wall of the volute 1 on the side away from the volute cover 2 to the volute cover 2. The first drainage section 8 is, for example, a water guiding rib, and its structure can be the same as that of the first water guiding rib 3, that is, both are flat plate structures or arc plate structures. Here, the flat plate or arc plate refers to that the cross section of the plate structure is a straight line or an arc.

[0060] In one embodiment, the volute 1 includes an air outlet, and the air outlet is located on the side away from the volute cover 2. The first water guiding rib 3 and the first drainage section 8 cooperate with each other to form a structure similar to a ring, wrap the upper part of the air outlet of the volute 1, and block the lower part of the air outlet of the volute 1, so that the condensed water generated on the volute 1 can be completely collected and guided away by the first water guiding rib 3 and the first drainage section 8. Specifically, the first water guiding rib 3 and the first drainage section 8 are combined together to form a major arc section and a minor arc section. The major arc section is an arc structure and is arranged above the minor arc section and covers the air outlet. One end of the confluence section 4 of the first water guiding rib 3 is connected to the major arc section, and the other end is connected to the first drainage section 8. The minor arc section includes the confluence section 4 and the first drainage section 8. The confluence section 4 of the first water guiding rib 3 is connected to the first drainage section 8 to block the flow path of the condensed water at the lower part of the volute 1 and prevent the condensed water from leaking from the connection position between the confluence section 4 and the first drainage section 8.

[0061] The first drainage section 8 includes two parts, a first part and a second part. Both the first part and the second part are flow guide plates. The first part is connected to the end of the major arc section to guide the condensed water on the outer surface of the major arc section. The second part is connected to the confluence section 4 to guide the condensed water on the part of the volute 1 located inside the first water diversion rib 3 and the first drainage section 8. The first part and the second part are arranged at intervals in the up and down direction, and a water outlet is formed between the first part and the second part. The condensed water on the second part flows out through this water outlet.

[0062] The first drainage section 8 also includes a part located on the outer peripheral wall of the volute 1. Since the first drainage section 8 extends to the volute cover 2, it can guide the condensed water generated on the outer peripheral wall of the volute 1, so as to more comprehensively collect the condensed water generated on the volute 1.

[0063] The second drainage structure also includes a second drainage section 9, which is arranged on the outer side wall of the volute cover 2. The second drainage section 9 can guide the condensed water generated on the volute cover 2, so as to facilitate the timely and rapid discharge of the condensed water on the volute cover 2.

[0064] For the fresh air component, when designing the drainage structure, it is impossible to ensure that the lowest drainage point of all part structures must be on the volute 1, and the lowest drainage point of other part structures may be lower than the lowest drainage point on the volute 1. Therefore, in this embodiment, by setting the first drainage structure and the second drainage structure, the condensed water on the outer shell can be respectively guided to different positions, so that different drainage lowest points can be formed by different structures, enabling the condensed water on different part structures to be discharged from the lowest drainage point, ensuring the complete discharge of the condensed water, with a simple structure, stronger compatibility, wider applicability, and can effectively solve the limitations of the drainage structure caused by the differences in different part structures, and stronger versatility.

[0065] In one embodiment, the first drainage section 8 and the second drainage section 9 are connected, and a second drainage port 11 is provided on the second drainage section 9. Part of the condensed water on the volute 1 is drained to the second drainage port 11 through the first drainage section 8 and the second drainage section 9.

[0066] In one embodiment, a second drainage port 11 is provided between the first drainage section 8 and the second drainage section 9. Part of the condensed water on the volute 1 is drained to the second drainage port 11 through the first drainage section 8, and the condensed water on the volute cover 2 is drained to the second drainage port 11 through the second drainage section 9.

[0067] Along the direction from the volute 1 to the volute cover 2, the height of the drainage surface of the first drainage section 8 gradually decreases.

[0068] As a preferred embodiment, the drainage surface of the first drainage section 8 decreases in height along the direction in which the condensed water flows to the second drain port 11, and the drainage surface of the second drainage section 9 decreases in height along the direction in which the condensed water flows to the second drain port 11.

[0069] In one embodiment, when the second drain port 11 is located on the second drainage section 9, the second drain port 11 is located at the middle position of the second drainage section 9. The second drainage section 9 is divided into two parts. The first part is disposed close to the first drainage section 8 and forms a sealed contact with the first drainage section 8. The second part is disposed away from the first drainage section 8, and the second drain port 11 is disposed at the connection position of the first part and the second part at the bottom.

[0070] The first part and the second part are joined at the bottom position to form a V-shaped confluence structure. The second drain port 11 is formed below the confluence structure. The setting relationship between the second drain port 11 and the confluence structure is similar to the relationship between the first drain port 5 and the confluence section 4, and will not be described in detail here.

[0071] In this embodiment, since the first drainage section 8 is provided with two layers, the second drainage section 9 is accordingly provided with two layers. When the first drainage section 8 is provided with other numbers of layers, the number of layers of the second drainage section 9 may or may not match the number of layers of the first drainage section 8.

[0072] In one embodiment, the housing further includes a sealing cover 13. The sealing cover 13 is disposed on the side of the volute cover 2 away from the volute 1. The second drainage structure further includes a third drainage section 10. The third drainage section 10 is disposed outside the sealing cover 13.

[0073] In one embodiment, the third drainage section 10 drains the condensed water on the sealing cover 13 to the side where the second drainage section 9 is located.

[0074] By providing the third drainage section 10, it can cooperate with the first drainage section 8 and the second drainage section 9 to form a more comprehensive collection and drainage of the condensed water on the housing surface. On the one hand, it avoids the high-altitude dripping of the condensed water, and on the other hand, it can effectively prevent the condensed water from entering the interior of the fresh air component, affecting the service life and air quality of the fresh air component.

[0075] In one embodiment, the third drainage section 10 is connected to the second drainage section 9. The second drain port 11 is provided on the second drainage section 9. The condensed water on the sealing cover 13 is drained to the second drain port 11 through the third drainage section 10 and the second drainage section 9.

[0076] In one embodiment, the second drain port 11 is provided between the third drainage section 10 and the second drainage section 9. The condensed water on the sealing cover 13 is drained to the second drain port 11 through the third drainage section 10, and the condensed water on the volute cover 2 is drained to the second drain port 11 through the second drainage section 9.

[0077] Refer to the combination of Figure 11 As shown, in one embodiment, the first drainage section 8 is connected to the second drainage section 9, and the third drainage section 10 is connected to the second drainage section 9. A second drain port 11 is provided on the second drainage section 9. Part of the condensed water on the volute 1 is drained to the second drain port 11 through the first drainage section 8 and the second drainage section 9, and the condensed water on the sealing cover 13 is drained to the second drain port 11 through the third drainage section 10 and the second drainage section 9.

[0080] When the second drain port 11 is located on the second drainage section 9, the second drainage section 9 and the third drainage section 10 are hermetically connected, so as to ensure that the condensed water on the sealing cover 13 can be smoothly discharged from the second drain port 11 and no leakage occurs at the connection position between the second drainage section 9 and the third drainage section 10.

[0081] In one embodiment, the first drainage structure and / or the second drainage structure is integrally injection-molded on the outer shell, which can not only reduce the assembly of structural parts, ensure the sealing connection effect between the first drainage structure and the second drainage structure and the outer shell, avoid the leakage of condensed water, but also use the first drainage structure and the second drainage structure to enhance the overall structural strength of the outer shell and effectively improve the production efficiency.

[0082] The fresh air component further includes a fixing frame 19 and a wind wheel 20, wherein the wind wheel 20 is installed in the volute 1, and the volute 1 is installed on the fixing frame 19.

The condensed water flowing together on the volute 1, the volute cover 2 and the sealing cover 13 is drained to the drainage groove on the bottom case 14 through the first drainage structure and the second drainage structure. Among them, a part of the condensed water on the volute 1 is discharged to the front drainage groove 15 of the bottom case 14 through the first drainage port 5 thereon, and another part of the condensed water on the volute 1 and the condensed water on the volute cover 2 and the sealing cover 13 are discharged to the back drainage groove 16 of the bottom case 14 together through the drainage port on the second drainage structure.

[0086] In one embodiment, a communication groove 18 is provided on the bottom case 14. The first end of the communication groove 18 is communicated with the front drainage groove 15, and the second end of the communication groove 18 is communicated with the back drainage groove 16, so that the front drainage groove 15 and the back drainage groove 16 can be communicated, so that the condensed water can finally flow into the drainage groove with a lower position and be finally discharged from the drainage groove with a lower position.

[0087] In one embodiment, a drain pipe 17 is connected to the bottom case 14. The drain pipe 17 is communicated with the front drainage groove 15. The condensed water drained by the second drainage structure passes through the back drainage groove 16 and the communication groove 18, and after converging with the condensed water drained by the first drainage structure in the front drainage groove 15, it is discharged from the drain pipe 17.

[0088] According to an embodiment of the present application, the fresh air conditioner includes the above-mentioned fresh air component or the above-mentioned drainage structure.

[0089] The flow process of the condensed water is as follows:

[0090] The condensed water on the volute 1 of the fresh air component is divided into two parts. One part of the water flow flows out of the first drainage port 5 on the volute 1 through the first drainage structure on the volute 1 and enters the front drainage groove 15 of the bottom case 14; the other part of the water flow flows through the first drainage section 8 on the volute 1, flows through the second drainage section 9 on the volute cover 2, and then flows out of the second drainage port 11 on the volute cover 2 and enters the back drainage groove 16 of the bottom case 14.

[0091] The condensed water on the volute cover 2 is drained to the second drain port 11 through the second drainage section 9 thereon, and then flows out through the second drain port 11 on the volute cover 2 and enters the dorsal drainage groove 16 of the bottom case 14.

[0092] The condensed water on the sealing cover 13 flows through the third drainage section 10 thereon, then through the second drainage section 9 on the volute cover 2, and finally flows out through the second drain port 11 on the volute cover 2 and enters the dorsal drainage groove 16 of the bottom case 14.

[0093] The condensed water that enters the front drainage groove 15 of the bottom case 14 flows along the front drainage groove 15 through the bottom case drain nozzle, and finally is discharged outside the air conditioner through the drain pipe 17. The condensed water that enters the dorsal drainage groove 16 of the bottom case 14 flows through the communication groove 18 to the front drainage groove 15 of the bottom case 14. After converging with the condensed water in the front drainage groove 15, it flows along the front drainage groove 15 through the bottom case drain nozzle, and finally is discharged outside the air conditioner through the drain pipe 17.

[0094] The operating principle and process of the fresh air air conditioner of the present application are as follows:

[0095] When the fresh air function is turned on and the air conditioner is operating, the fresh air component starts to operate. There is a phenomenon of alternating cold and heat inside the indoor unit of the air conditioner. The moisture in the air around the fresh air component is liquefied when cooled and adheres to the outer surface of the fresh air component, that is, on the surfaces of the volute 1, the volute cover 2 and the sealing cover 13. Innumerable small condensed water droplets gradually converge into larger condensed water droplets. Under the action of gravity, the large condensed water droplets slowly flow down along the water guiding ribs of the drainage structure from the volute 1, the volute cover 2 and the sealing cover 13, and gather at the drain port of the drainage structure. Then the condensed water is discharged from the drain port and drained to the bottom case drainage groove below.

[0096] The condensed water on the surface of the fresh air component is divided into two parts: a part of the condensed water on the volute 1 is discharged from the first drain port 5 on the volute 1, enters the front drain groove 15 of the bottom shell 14 below, then flows through the drain nozzle on the bottom shell 14, and flows into the drain pipe 17 through the drain nozzle, and then the condensed water is discharged from the air conditioner indoor unit through the drain pipe 17; another part of the condensed water on the volute 1 and the condensed water on the volute cover 2 and the sealing cover 13 are discharged through the second drain port 11 on the volute cover 12 to the back drain groove 1 6, and then flows through the front drainage groove 15 of the bottom shell 14, flows through the drainage nozzle on the bottom shell 14, and flows into the drainage pipe 17 through the drainage nozzle, and finally the condensed water is discharged from the air conditioner through the drainage pipe 17, that is, there is a section of condensed water flow path in the front drainage groove 15 of the bottom shell 14 that is shared, and the condensed water drained by the first drainage structure and the second drainage structure all flows through the front drainage groove 15 of the bottom shell 14, and then flows to the drainage nozzle of the bottom shell, and then through the drainage pipe 17, the condensed water is discharged to the outside of the air conditioner, and the whole process ends here. The above scheme is not only simple and efficient, but also does not need to absorb the condensed water, and the condensed water can be drained and discharged in time, so it can greatly reduce or eliminate the sponge used for heat preservation, and can achieve continuous operation.

[0097] When the air conditioner is running with the fresh air function turned off, the indoor unit of the air conditioner will still experience alternating hot and cold temperatures, which can easily produce condensation. The drainage structure in the present application also maintains the original water diversion / drainage function without the need to turn on the fresh air component. The condensation will also be discharged from the indoor unit of the air conditioner to the outside of the air conditioner according to the above process, thereby achieving the effect of quickly discharging the condensation.

[0098] During the operation of the fresh air air conditioner of the present application, condensation water of all sizes generated on the surface of the fresh air component will not enter the interior of the fresh air component, nor will it run to places other than the drainage groove of the bottom shell, and will not adhere to the surface of each part for a long time, so that the outer surface of the fresh air component always remains dry, thereby achieving the purpose of preventing the accumulation of condensation water in the present application.

[0099] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0100] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
