Referring to fig. 3 to 7, a flow guide member 100 according to an embodiment of the present disclosure includes an exhaust pipe 10 and a plurality of flow guide ribs 20. The exhaust pipe 10 comprises a first part 11 and a second part 12, the first part 11 and the second part 12 jointly define an air flow channel 13, a separation channel 14, an air outlet 16 and an air outlet 15, the air flow channel 13 and the separation channel 14 are arranged at intervals along the direction perpendicular to the extension direction of the air flow channel 13, the first part 11 and the second part 12 are provided with a combined position in a fused connection, the combined position is at a position of the separation channel 14 far away from the air flow channel 13, and the air outlet 15 and the air outlet 16 are both positioned at the downstream of the air flow channel 13 and are communicated with the air flow channel 13. The plurality of flow guide ribs 20 are arranged on at least one inner wall surface of the airflow channel 13, the plurality of flow guide ribs 20 are arranged at intervals along the extending direction of the airflow channel 13, a part of the flow guide ribs 20 are arranged close to the isolation channel 14, and the flow guide ribs 20 are used for guiding the condensed water to the water outlet 15.

In the diversion part 100 of the embodiment of the present application, the exhaust pipe 10 is divided into the first part 11 and the second part 12 to facilitate the manufacture and installation of the exhaust pipe 10, the high temperature and high humidity air in the chamber can be discharged through the airflow channel 13 of the exhaust pipe 10, the condensed water is formed on the inner wall of the airflow channel 13, and the diversion rib 20 is used for guiding the condensed water to flow to the water outlet 15. The joint of the first part 11 and the second part 12 is located on one side of the isolation channel 14 far away from the airflow channel 13, so that the condensed water can smoothly flow down along the airflow channel 13 and flow out towards the water outlet 15 under the guidance of the flow guide rib 20, and the joint is prevented from influencing the flow of the condensed water on the inner wall of the airflow channel 13.

Specifically, the exhaust pipe 10 may be installed outside the cavity 301, and the inside of the exhaust pipe 10 is hollow to form the air flow passage 13. The two ends of the exhaust pipe 10 may be open, wherein one end is an air inlet 17, the other end is an air outlet 16, and both the air inlet 17 and the air outlet 16 are communicated with the air flow channel 13. A water outlet 15 is formed at one end of the air outlet 16 of the exhaust pipe 10, and the water outlet 15 is also communicated with the airflow channel 13.

A plurality of flow guiding ribs 20 may be formed on an inner wall surface of the airflow channel 13, and the flow guiding ribs 20 may be formed by protruding the inner wall surface of the exhaust pipe 10 toward the center of the airflow channel 13. The flow guiding ribs 20 may be arranged in a strip structure, the flow guiding ribs 20 may extend to one side of the water outlet 15 along the extending direction of the airflow channel 13 in an inclined manner, and then the condensed water formed on the inner wall surface of the airflow channel 13 can flow out from the water outlet 15 along the extending direction of the flow guiding ribs 20 under the action of the flow guiding ribs 20.

It should be noted that the air inlet 17 of the air flow channel 13 may be communicated with the chamber of the washing appliance 300, so that the air flow formed in the chamber can be guided into the air flow channel 13 through the air inlet 17. Wherein the air inlet 17 may communicate with the chamber at a position near the top of the washing appliance 300, and the air outlet 16 and the water outlet 15 of the air flow channel 13 may be disposed at a position near the bottom of the washing appliance 300.

It can be understood that when the washing appliance 300 dries the dishes inside, the high-temperature and high-humidity air inside the cavity 301 can be guided into the airflow channel 13 of the exhaust duct 10 through the air inlet 17 and exhausted by the fan 201. Because the temperature in the exhaust pipe 10 is relatively low, the high-temperature and high-humidity air can generate condensed water on the inner wall of the airflow channel 13 under the condition of sudden temperature drop, and the condensed water can flow to the water outlet 15 along the inner wall of the airflow channel 13 under the guidance of the flow guide rib 20 and is discharged from the water outlet 15, so that the airflow guided out from the air outlet 16 is relatively dry, and the condition that the guided airflow forms the condensed water outside to influence the operation of components in the washing appliance 300 is avoided.

Further, in order to facilitate the manufacturing and installation of the exhaust pipe 10, the exhaust pipe 10 can be split into the first part 11 and the second part 12, and the first part 11 and the second part 12 can be connected together by glue or welding. If the first portion 11 and the second portion 12 are directly sealed to form the airflow channel 13 for welding, a raised welding point or an overflow colloid and the like are formed on the inner wall surface of the airflow channel 13, so that the flow of condensed water on the inner wall surface of the airflow channel 13 is influenced, and the problem can be solved by positioning the joint part of the first portion 11 and the second portion 12 on the outer wall surface of the airflow channel 13.

The first portion 11 and the second portion 12 may define an airflow channel 13 and a separation channel 14, the separation channel 14 may be formed on a side of the airflow channel 13, and an extending direction of the separation channel 14 is the same as an extending direction of the airflow channel 13. The joint of the first part 11 and the second part 12 is located on the isolation channel 14, so that the flow of the condensed water in the air flow channel 13 is not affected, and the isolation channel 14 can make the exhaust pipe 10 relatively sealed, so as to avoid air leakage when air flows in the exhaust pipe 10.

Referring to fig. 3 to 7, in some embodiments, the first portion 11 includes a first tube wall 111, a second tube wall 112, and a first connecting wall 113, the second tube wall 112 is connected to the first tube wall 111, the first connecting wall 113 is connected to the second tube wall 112 and located outside the airflow channel 13, the second portion 12 includes a third tube wall 121 and a second connecting wall 122, and the second connecting wall 122 is connected to an edge of the third tube wall 121;

Thus, the airflow channel 13 can be defined by the inner wall surfaces of the first tube wall 111, the second tube wall 112 and the third tube wall 121, the isolation channel 14 can be defined by the outer wall surface of the second tube wall 112 and the inner wall surfaces of the third tube wall 121, the first connecting wall 113 and the second connecting wall 122, the first part 11 and the second part 12 are connected together through the first connecting wall 113 and the second connecting wall 122, and further, the joint part is formed at the isolation channel 14, and the flow of condensed water in the airflow channel 13 cannot be influenced.

Specifically, the first tube wall 111, the second tube wall 112, the third tube wall 121, the first connecting wall 113, and the second connecting wall 122 may be disposed in a strip-shaped plate-shaped structure. The first tube wall 111 may be connected to the second tube wall 112 in a bending manner, and the first connecting wall 113 may extend from the outer wall of the second tube wall 112 to the side opposite to the air flow channel 13. The second connecting wall 122 may be connected to the third pipe wall 121 and extend to the second connecting wall 122.

The inner walls of the first tube wall 111, the second tube wall 112 and the third tube wall 121 may be smoothly arranged, so as to facilitate the downward flow of the condensed water and reduce the resistance of the airflow in the airflow channel 13. The first tube wall 111, the second tube wall 112 and the third tube wall 121 may each have a flow guiding rib 20 formed thereon, and the water outlet 15 may be formed at one side of the end portions of the first flow guiding rib 21 and the third flow guiding rib 23, so that the flow guiding rib 20 guides the condensed water to flow to the water outlet 15.

When the first portion 11 and the second portion 12 are combined, the end portion, opposite to the first tube wall 111, of the second tube wall 112 is attached to the inner wall surface of the third tube wall 121, the end, close to the third tube wall 121, of the flow guide rib 20 on the second tube wall 112 is in adaptive connection with the end, close to the second tube wall 112, of the flow guide rib 20 on the third tube wall 121, so that the inner wall of the airflow channel 13, which is surrounded by the first tube wall 111, the second tube wall 112 and the third tube wall 121, can be more tight and smooth, the flow guide rib 20 on the second tube wall 112 and the flow guide rib 20 on the third tube wall 121 can also more smoothly guide the condensed water, and the attachment position of the second tube wall 112 and the third tube wall 121 does not influence the flow of the condensed water on the inner wall surface of the airflow channel 13.

Referring to fig. 3 to 7, in some embodiments, the flow guiding ribs 20 include first flow guiding ribs 21, second flow guiding ribs 22, and third flow guiding ribs 23, the first flow guiding ribs 21 are disposed on the first tube wall 111, the second flow guiding ribs 22 are disposed on the second tube wall 112, the third flow guiding ribs 23 are disposed on the third tube wall 121, the second flow guiding ribs 22 are configured to guide the condensed water to the first flow guiding ribs 21 and/or the third flow guiding ribs 23 so as to be guided to the water outlet 15 through the first flow guiding ribs 21 and/or the third flow guiding ribs 23, and the first flow guiding ribs 21, the second flow guiding ribs 22, and the third flow guiding ribs 23 are all plural in number and are all arranged at intervals along the extending direction of the airflow channel 13.

Therefore, the condensed water formed on the first tube wall 111, the second tube wall 112 and the third tube wall 121 can be collected on the tube wall on one side of the water outlet 15 and flow to the water outlet 15 along the tube wall under the guidance of the first flow guiding rib 21, the second flow guiding rib 22 and the third flow guiding rib 23, respectively.

Specifically, two ends of the second flow guiding rib 22 may be connected to the first flow guiding rib 21 and the third flow guiding rib 23, and the first flow guiding rib 21 and the third flow guiding rib 23 both extend in an inclined manner toward the water outlet 15. The upper surfaces of the first flow guiding rib 21, the second flow guiding rib 22 and the third flow guiding rib 23 belong to the same horizontal plane.

The condensed water formed on the second pipe wall 112 can flow onto the first flow guiding rib 21 and/or the third flow guiding rib 23 under the guidance of the second flow guiding rib 22, and then flow to the water outlet 15 under the guidance of the first flow guiding rib 21 and the third flow guiding rib 23; the condensed water formed on the first tube wall 111 and the third tube wall 121 can flow to the water outlet 15 under the guidance of the first flow guiding rib 21 and the third flow guiding rib 23, so that the condensed water in the airflow channel 13 can flow to the water outlet 15 along the side of the water outlet 15, which is avoided, so as to collect the condensed water in a concentrated manner.

Form a plurality of water conservancy diversion muscle 20 on every pipe wall and can guide the comdenstion water better, avoid when the water yield of comdenstion water is too big, single water conservancy diversion muscle 20 can't guide whole water yield, and then excessive comdenstion water then can flow down and can't be guided to delivery port 15 along the pipe wall that corresponds, and the comdenstion water rivers just can influence the user to use to experience to the outside.

Referring to fig. 5 and 6, in some embodiments, the second tube wall 112 is provided with a mounting groove 18, the mounting groove 18 communicates with the airflow channel 13 and the isolation channel 14, and the third tube wall 121 is provided with a flow guiding rib 20, and the flow guiding rib 20 is at least partially inserted into the mounting groove 18.

Therefore, the third diversion rib 23 penetrates through the installation groove 18 and extends into the isolation channel 14, so that the first part 11 and the second part 12 can be easily installed in an aligned mode, and installation dislocation of the first part 11 and the second part 12 is avoided. Meanwhile, the third flow guiding rib 23 and the second flow guiding rib 22 can be connected in an aligned manner, so that the condensed water formed on the second pipe wall 112 can be guided by the second flow guiding rib 22 and the third flow guiding rib 23 to flow to the water outlet 15.

Specifically, the mounting groove 18 may be formed on one side of the end surface of the second tube wall 112 facing the third tube wall 121, and is located at the same horizontal position as the second flow guiding rib 22, and the depth and the shape of the mounting groove 18 may be adapted to the third flow guiding rib 23. Furthermore, when the first portion 11 and the second portion 12 are combined, the third diversion rib 23 can be clamped in the mounting groove 18 and connected with the second diversion rib 22, so that the condensed water formed on the second pipe wall 112 can better flow to the third diversion rib 23 along the second diversion rib 22.

Meanwhile, the third flow guide ribs 23 are clamped in the mounting grooves 18, so that the first part 11 and the second part 12 can be better installed in an aligned mode, dislocation in the extending direction of the airflow channel 13 when the first part 11 and the second part 12 are installed is prevented, and installation is more convenient and accurate.

Referring to fig. 4 and 5, in some embodiments, the second tube wall 112 has a return hole 19, and the return hole 19 communicates with the airflow channel 13 and the isolation channel 14 and is disposed near the air outlet 16.

Thus, the third flow guiding rib 23 extends into the isolation channel 14 through the return hole 19, so that the condensed water seeped out from the connection gap between the second pipe wall 112 and the third pipe wall 121 can be prevented from flowing out along the isolation channel 14.

Specifically, the backflow hole 19 may also be opened on the end surface side of the second pipe wall 112 facing the third pipe wall 121, and is at the same horizontal position as the second flow guiding rib 22. The aperture of the backflow hole 19 in the extending direction of the airflow channel 13 may be slightly larger than the thickness of the third flow guiding rib 23, that is, when the third flow guiding rib 23 is clamped in the backflow hole 19, the bottom surface of the third flow guiding rib 23 may be connected to the bottom surface of the backflow hole 19, and the top surface of the third flow guiding rib 23 may be spaced from the top surface of the backflow hole 19 appropriately.

The third flow guiding rib 23 can penetrate through the backflow hole 19 and extend into the isolation channel 14, so that the condensed water seeped out from the connection gap between the second pipe wall 112 and the third pipe wall 121 can flow onto the third flow guiding rib 23 along the outer wall surface of the second pipe wall 112, and flows to the water outlet 15 through the backflow hole 19 under the guidance of the third flow guiding rib 23, so that the condensed water seeped out from the connection gap between the second pipe wall 112 and the third pipe wall 121 is prevented from directly flowing out along the isolation channel 14, and the dryness degree inside the washing appliance 300 is effectively improved.

In this way, the condensed water formed in the airflow channel 13 can flow to the fifth pipe wall 114 and flow along the inner wall of the fifth pipe wall 114 toward the water outlet 15 under the guidance of the first flow guiding rib 21, and can flow to the fourth pipe wall 123 and flow along the inner wall of the fourth pipe wall 123 toward the water outlet 15 under the guidance of the third flow guiding rib.

Specifically, the fourth tube wall 123 may be connected to a side of the third tube wall 121 opposite to the second connecting arm and bent toward the first tube wall 111, and the fifth tube wall 114 may be connected to a side of the first tube wall 111 opposite to the second tube wall 112 and bent toward the third tube wall 121. Fourth tube wall 123 is connected to fifth tube wall 114 when first portion 11 and second portion 12 are joined. The airflow channel 13 may be enclosed by a first pipe wall 111, a second pipe wall 112, a third pipe wall 121, a fourth pipe wall 123 and a fifth pipe wall 114, and the water outlet 15 is disposed below the fourth pipe wall 123 and the fifth pipe wall 114.

Because the water outlet 15 is located on one side of the fourth pipe wall 123 and one side of the fifth pipe wall 114, the water guiding ribs 20 do not need to be arranged on the fourth pipe wall 123 and the fifth pipe wall 114, the condensed water is guided by the water guiding ribs 20 and is collected on one side of the fourth pipe wall 123 and one side of the fifth pipe wall 114, the condensed water only needs to flow towards the water outlet 15 along the inner wall, and further, even if a welding point is formed at the joint of the fourth pipe wall 123 and the fifth pipe wall or glue overflow occurs, the flow of the condensed water cannot be influenced, the fourth pipe wall 123 and the fifth pipe wall 114 can be tightly combined to avoid the leakage of the condensed water from the gap, and the combination of the condensed water at the joint does not need to be avoided.

Referring to fig. 7, in some embodiments, the included angle between the first tube wall 111 and the second tube wall 112 is an acute angle. Since the first portion 11 can be formed by injection molding, if the first tube wall 111 is disposed perpendicular to the second tube wall 112, it is not easy to separate from the mold during demolding, and the first tube wall 111 and the second tube wall 112 form a certain angle to facilitate demolding of the first portion 11. Similarly, the second portion 12 is adapted to the first portion 11, which also facilitates demolding of the second portion 12.

Referring to fig. 3-5, in some embodiments, the exhaust pipe 10 is provided with a water containing groove 31, and the water containing groove 31 is disposed between the airflow channel 13 and the water outlet 15 and connects the airflow channel 13 and the water outlet 15. Thus, the condensed water flowing down the inner wall surface of the airflow channel 13 can flow into the water containing tank 31 and then be discharged through the water outlet 15. The water containing tank 31 can temporarily collect the condensed water, so that the phenomenon that the water flow is too large is avoided, and the water outlet 15 cannot discharge all the condensed water instantly to overflow the water outlet 15.

In some embodiments, the flow directing member 100 includes a water nozzle 32 in communication with the water outlet 15 and disposed outside the airflow passageway 13. Thus, the water outlet 15 can be connected with an external pipeline through the water nozzle 32 to lead out the condensed water. The water nozzle 32 can be connected with an external pipeline more tightly, so that the water leakage is avoided.

In some embodiments, the dimension between the end of the air guide rib 20 away from the inner wall surface and the inner wall surface ranges from 2mm to 10mm.

Therefore, the flow guiding ribs 20 can guide the condensed water to the water outlet 15, and meanwhile, the flow of the airflow in the airflow channel 13 is not influenced, and the resistance to the airflow is reduced.

Specifically, the height of the diversion rib 20 protruding from the inner wall surface of the exhaust pipe 10 may be 2mm, 3mm, 5mm, 8mm, 10mm, or the like, which is not limited in the present application. The too high protruding height of the flow guiding rib 20 will affect the flowing speed of the airflow in the airflow channel 13, and further affect the drying process of the washing appliance 300; if the protruding height of the flow guiding rib 20 is too low, the condensed water cannot be guided to flow to the water outlet 15, and the condensed water flows out of the airflow channel 13 along the corresponding wall surface, so that the internal of the washing appliance 300 is affected by damp or short circuit of elements, and the use safety and the service life of the washing appliance 300 are affected.
