Description

Technical Field

[0001] This utility model relates to the field of washer-dryer technology, and more specifically, to a rear drum component and a washer-dryer having the same. Background Technology

[0002] For popular washer-dryers on the market, the drying process involves condensation on the inner surface of the rear drum. The key to this condensation process is guiding the condensate along specific guide ribs to ensure that the condensate can fully contact the hot and humid air and exchange heat, thereby achieving effective drying of clothes.

[0003] However, the current design has certain limitations, especially in the initial flow stage of condensate. When condensate flows out of the outlet, it is affected by the mold during the assembly of the rear drum structure, leading to instability in the water flow path. Specifically, when condensate just flows out of the outlet and has not yet reached the first guide rib, it may deviate from its original flow direction due to irregular seams on the inner surface of the rear drum, or even be dispersed by the airflow and splash into the inner drum, directly wetting the clothes, thereby reducing drying efficiency and prolonging drying time. Utility Model Content

[0004] The main objective of this invention is to provide a rear drum component and a washer-dryer having the same, so as to solve the problem that the condensate on the rear drum deviates from its intended flow direction when the washer-dryer is in operation.

[0005] To achieve the above objectives, according to one aspect of the present invention, a rear cylinder component is provided, including a main body and a condensate outlet and a guide rib spaced apart on the main body. The rear cylinder component further includes a flow guiding structure disposed between the condensate outlet and the guide rib. The flow guiding structure includes a first flow guiding portion and a second flow guiding portion, which are spaced apart and opposite to each other along a first direction to form a limiting space for guiding condensate. The two ends of the limiting space are respectively disposed corresponding to the condensate outlet and the guide rib. The first flow guiding portion and the second flow guiding portion both extend from the condensate outlet to the guide rib, so that the condensate flowing out of the condensate outlet flows onto the guide rib.

[0006] Furthermore, both the first and second guide sections are spaced apart from the condensate outlet; and / or both the first and second guide sections are spaced apart from the guide ribs; and / or the first and second guide sections are symmetrically arranged.

[0007] Furthermore, the minimum distance between the first guide section and the second guide section in the first direction is greater than or equal to the maximum width of the condensate outlet in the first direction, and the maximum distance between the first guide section and the second guide section in the first direction is less than twice the maximum width of the condensate outlet in the first direction.

[0008] Furthermore, the perpendicular line connecting the first guide section and the second guide section, which is parallel to the first direction, coincides with the line connecting the center of the condensate outlet and the branching point of the guide rib.

[0009] Furthermore, the first guide section and the second guide section are arranged parallel to each other, both of which are perpendicular to the first direction, and the cross-sections of the first guide section and the second guide section are rectangular.

[0010] Furthermore, the first guide section and the second guide section are respectively inclined in the first direction, and the cross-section of the first guide section and the second guide section is rectangular. The width of the limiting space in the first direction gradually increases or decreases from the condensate outlet to the guide rib.

[0011] Furthermore, the angle between the first guide portion and the first direction is greater than or equal to 60 degrees and less than 90 degrees; and / or the angle between the second guide portion and the first direction is greater than or equal to 60 degrees and less than 90 degrees; and / or the length of the first guide portion and the second guide portion is greater than or equal to 10 mm and less than 20 mm; and / or the thickness of the first guide portion and the second guide portion is greater than or equal to 2 mm and less than or equal to 3.5 mm.

[0012] Furthermore, the first guide portion and the second guide portion are respectively a first arc-shaped protrusion and a second arc-shaped protrusion, and the width of the limiting space in the first direction gradually decreases from the middle to both ends; or the first guide portion and the second guide portion are respectively a third arc-shaped protrusion and a fourth arc-shaped protrusion, and the width of the limiting space in the first direction gradually increases from the middle to both ends.

[0013] Furthermore, both the first and second flow guides include a first plate and a second plate connected in sequence, with the first plate and the second plate forming a first predetermined angle, and the width of the limiting space in the first direction gradually decreasing from the middle to both ends; or both the first and second flow guides include a third plate and a fourth plate connected in sequence, with the first plate and the second plate forming a second predetermined angle, and the width of the limiting space in the first direction gradually increasing from the middle to both ends.

[0014] According to another aspect of the present invention, a washer-dryer is also provided, including the aforementioned rear drum component.

[0015] By applying the technical solution of this utility model, the rear drum component of this application includes a flow guiding structure disposed between the condensate outlet and the flow guiding ribs. The flow guiding structure is provided with a first flow guiding part and a second flow guiding part spaced apart along a first direction to form a limiting space for guiding the condensate. This ensures that the condensate will not deviate from the ideal flow path due to structural changes inside the rear drum. This allows the condensate to flow more smoothly and evenly onto the flow guiding ribs, increasing the contact area and time between the condensate and the hot, humid air, thereby significantly improving condensation efficiency and drying effect. By limiting the flow range of the condensate, this application also avoids the situation where condensate splashes into the inner drum and wets clothes due to changes in the water path, reducing the possibility of clothes accidentally getting soaked during the drying process and improving the user experience. Furthermore, the use of the flow guiding structure allows the condensate to more accurately cover the inner surface of the rear drum, enabling more effective exchange with the hot, humid air, promoting the condensation of moisture in the air, accelerating the drying process of clothes, and effectively solving the problem in existing washer-dryers where the condensate on the rear drum deviates from its intended flow direction during operation.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 6 As shown, the rear cylinder component of this application includes a main body 10 and a condensate outlet 20 and a guide rib 30 spaced apart on the main body 10. The rear cylinder component also includes a guide structure 40 disposed between the condensate outlet 20 and the guide rib 30. The guide structure 40 includes a first guide portion 410 and a second guide portion 420. The first guide portion 410 and the second guide portion 420 are spaced apart and opposite to each other along a first direction to form a limiting space 430 for guiding condensate. The two ends of the limiting space 430 are respectively corresponding to the condensate outlet 20 and the guide rib 30. The first guide portion 410 and the second guide portion 420 both extend from the condensate outlet 20 to the guide rib 30 so that the condensate flowing out of the condensate outlet 20 flows onto the guide rib 30.

[0028] Thus, the rear cylinder component of this application includes a flow guiding structure disposed between the condensate outlet 20 and the guide rib 30. The flow guiding structure is provided with a first guide portion 410 and a second guide portion 420 spaced apart along a first direction to form a limiting space 430 for guiding the condensate. This ensures that the condensate will not deviate from the ideal flow path due to structural changes inside the rear cylinder, such as mold seams or vibrations. This allows the condensate to flow more smoothly and evenly onto the guide rib 30, increasing the contact area and time between the condensate and the hot, humid air, thereby significantly improving the condensation efficiency. Regarding efficiency and drying effect, this application limits the flow range of condensate water, preventing condensate water from splashing into the inner drum and wetting clothes due to changes in the water path. This reduces the possibility of clothes getting accidentally soaked during the drying process, improving the user experience. Furthermore, the use of the flow guiding structure allows condensate water to more accurately cover the inner surface of the rear drum, facilitating more effective exchange with hot and humid air, promoting the condensation of moisture in the air, and accelerating the drying process of clothes. This effectively solves the problem in existing washer-dryers where condensate water on the rear drum deviates from its intended flow direction during operation.

[0029] Preferably, the first direction in this application is the horizontal direction.

[0030] like Figure 1As shown, the first guide section 410 and the second guide section 420 are both spaced apart from the condensate outlet 20, which avoids the condensate being directly impacted by the outlet edge, reduces the phenomenon of water droplet dispersion, and ensures the continuity and stability of the water flow. The first guide section 410 and the second guide section 420 are both spaced apart from the guide ribs 30, rather than directly contacting or merging with them, which provides a clear flow guide for the condensate, making it flow more concentratedly to the guide ribs, rather than spreading randomly, thereby improving the uniformity of the condensate distribution in the rear cylinder.

[0031] In this application, the first guide section 410 and the second guide section 420 are symmetrically arranged. The symmetrical arrangement of the first guide section and the second guide section can ensure that the condensate is distributed more evenly on the inner surface of the rear cylinder, avoid the phenomenon of water concentration that may be caused by unilateral guide, optimize the contact area between hot and humid air and condensate, and thus improve the condensation efficiency.

[0032] Preferably, this application maintains a certain distance between the first guide section 410 and the second guide section 420 and the condensate outlet 20 and the guide rib 30, which can reduce the mutual influence between the components, such as avoiding the water flow being restricted by the outlet shape or the physical obstruction of the guide rib, and ensuring the freedom and smoothness of the condensate flow.

[0033] Specifically, the minimum distance between the first guide section 410 and the second guide section 420 in the first direction is greater than or equal to the maximum width of the condensate outlet 20 in the first direction, and the maximum distance between the first guide section 410 and the second guide section 420 in the first direction is less than twice the maximum width of the condensate outlet 20 in the first direction.

[0034] This application, by setting a minimum distance greater than or equal to the maximum width of the condensate outlet 20, helps ensure that the condensate can stably enter and remain within the limiting space 430 after flowing out of the outlet. This avoids situations where the water flow is obstructed due to being too close or deviates from the limiting space 430 due to being too far away, thus ensuring the continuity and controllability of the water flow in the first direction. The maximum distance is less than twice the maximum width of the condensate outlet 20. This design helps to finely adjust the coverage of the condensate inside the rear drum, ensuring that the moisture is evenly distributed on the expected guide ribs 30, without excessive diffusion, which would affect the drying efficiency and the drying quality of the clothes.

[0035] Optionally, the perpendicular line connecting the first guide section 410 and the second guide section 420, parallel to the first direction, coincides with the line connecting the center of the condensate outlet 20 and the branching point 310 of the guide rib. This ensures that after the condensate flows out of the outlet, it can be precisely guided along an ideal straight path to the branching point of the guide rib 30, enhancing the accuracy of water path guidance and preventing deviation of the water path due to changes in the internal structure of the rear cylinder. Through precise alignment, the condensate can more effectively contact the guide rib, forming a uniform water film, increasing the contact area between hot and humid air and condensate, and directly improving condensation efficiency and drying performance.

[0036] like Figure 1 and Figure 2 As shown, in the first embodiment of this application, the first guide portion 410 and the second guide portion 420 are arranged parallel to each other, both the first guide portion 410 and the second guide portion 420 are perpendicular to the first direction, and the cross-sections of the first guide portion 410 and the second guide portion 420 are rectangular.

[0037] In this application, the first guide section 410 and the second guide section 420 are parallel to each other and perpendicular to the first direction. This design forms a clear and stable water guide channel, ensuring that the condensate can flow along the predetermined path and reducing water flow deviation caused by changes in the rear cylinder structure or vibration.

[0038] Preferably, the first guide section 410 and the second guide section 420 with rectangular cross sections form a uniform confined space between the condensate outlet 20 and the guide rib 30, which helps the condensate to be evenly distributed between the two guide sections, thereby forming a more uniform water film when it reaches the guide rib 30, increasing the contact area with hot and humid air, and optimizing the condensation effect.

[0039] like Figure 3 and Figure 4 As shown, in the second embodiment of this application, the first guide portion 410 and the second guide portion 420 are respectively inclined in the first direction, and the cross-sections of the first guide portion 410 and the second guide portion 420 are rectangular. The width of the limiting space 430 in the first direction gradually increases or decreases from the condensate outlet 20 to the guide rib 30.

[0040] With the inclined arrangement of the first guide section 410 and the second guide section 420, the condensate is given a specific guiding angle when it flows out of the outlet. This helps to control the flow direction and speed of the water. Even if the rear cylinder vibrates or under different operating conditions, the stability and controllability of the water path can be maintained. In addition, the gradually changing width of the limiting space 430 allows the condensate to be naturally distributed according to the change in the width of the space when it flows through this space. This avoids the water film being too thick or too thin in some places at the condensation ribs, ensuring the uniformity of contact between the condensate and the hot and humid air, thereby improving the condensation efficiency.

[0041] Specifically, the angle between the first guide portion 410 and the first direction is greater than or equal to 60 degrees and less than 90 degrees; and / or the angle between the second guide portion 420 and the first direction is greater than or equal to 60 degrees and less than 90 degrees; and / or the length of the first guide portion 410 and the second guide portion 420 is greater than or equal to 10 mm and less than 20 mm; and / or the thickness of the first guide portion 410 and the second guide portion 420 is greater than or equal to 2 mm and less than 3.5 mm.

[0042] The angle range in this application can significantly enhance the guiding effect of condensate, ensuring that the water flow is effectively restricted and guided on a larger inclined surface, reducing the possibility of deviating from the preset path. Moreover, the selection of the inclination angle optimizes the distribution efficiency of condensate. In particular, in the limiting space 430 with gradually changing width, condensate can be more evenly covered to the guide ribs 30 under the guidance of the first guide part 410 and the second guide part 420, which enhances the contact area between condensate and hot and humid air and improves condensation efficiency.

[0043] By setting the length of the guide section within the range of 10mm to 20mm, this application ensures sufficient space for hot and humid air to pass through, while avoiding excessive height that would obstruct airflow or excessive length that would affect the normal flow of condensate. This length design optimizes the interaction between air and condensate, improving drying efficiency. Furthermore, the 2mm to 3.5mm thickness of the first guide section 410 and the second guide section 420 provides sufficient support to prevent condensate from deviating from the predetermined path during flow, while also ensuring smooth flow of condensate and reducing obstruction.

[0044] Preferably, in a third embodiment not illustrated in this application, the first guide portion 410 and the second guide portion 420 are respectively a first arc-shaped protrusion and a second arc-shaped protrusion. The width of the limiting space 430 in the first direction gradually decreases from the middle to both ends. Compared with straight or acute-angle guidance, the arc-shaped protrusion design can guide the condensate more smoothly, reduce turbulence and splashing during water flow, and ensure the stable flow of condensate in the limiting space. Moreover, the characteristic that the width of the limiting space gradually decreases from the middle to both ends allows the condensate to naturally form a thicker water film in the middle part during the flow process, while gradually thinning towards both ends. This distribution pattern matches the characteristics of the natural flow of hot and humid air in the rear cylinder, thus optimizing the distribution of condensate.

[0045] In a fourth embodiment not illustrated in this application, the first guide portion 410 and the second guide portion 420 are respectively the third arc-shaped protrusion and the fourth arc-shaped protrusion. The width of the limiting space 430 gradually increases from the middle to both ends in the first direction. The limiting space design with the width gradually increasing from the middle to both ends can ensure that the condensate water is smoothly dispersed from the center to both ends of the rear drum, forming a more uniform water film distribution, thereby increasing the contact area with hot and humid air, optimizing the heat exchange efficiency, and forming a wider limiting space at both ends, which is conducive to the formation of a thinner water film on the inner surface of the rear drum, reducing water evaporation, improving condensation efficiency, and ensuring that the washer-dryer can reach the ideal drying state more quickly when drying clothes.

[0046] like Figure 5 and Figure 6 As shown, in the fifth embodiment of this application, the first guide section 410 and the second guide section 420 both include a first plate 440 and a second plate 450 connected in sequence. The first plate 440 and the second plate 450 are set at a first predetermined angle. The width of the limiting space 430 in the first direction gradually decreases from the middle to both ends. The guide section design composed of the first plate 440 and the second plate 450 in this application, combined with the setting of the first predetermined angle, can more accurately control the flow path of the condensate, ensure that the condensate flows along the preset direction, and reduce the water path deviation angle setting caused by mold connection or changes in the internal structure of the rear cylinder.

[0047] In the sixth embodiment not shown in this application, the first guide section 410 and the second guide section 420 both include a third plate and a fourth plate connected in sequence. The first plate 440 and the second plate 450 are set at a second predetermined angle. The width of the limiting space 430 in the first direction gradually increases from the middle to both ends. The design of the plates and the second predetermined angle causes the condensate to gradually diffuse from the central area to both sides, forming an adaptive water film distribution. This distribution pattern can better adapt to the diffusion characteristics of hot and humid air in the rear cylinder and improve the efficiency of heat exchange.

[0048] This application also provides a washer-dryer including the aforementioned rear drum component. The rear drum component of this application adopts an optimized design. Through the precise cooperation of the limiting component and the guide part, it ensures that the condensate is evenly distributed along a predetermined path on the entire inner surface of the rear drum, and fully exchanges heat with the hot and humid air, thereby significantly improving the drying efficiency of the washer-dryer. Furthermore, by controlling the width of the limiting space and the structure of the guide part, it can effectively avoid accidental changes in the water flow path, reduce the splashing and waste of condensate, and ensure that the washer-dryer can maintain stable condensate management under various operating conditions. This allows the washer-dryer to utilize energy more effectively when drying clothes, reduce power consumption, and improve energy efficiency.

The rear cylinder component also includes a guide structure 40 disposed between the condensate outlet 20 and the guide rib 30. The guide structure 40 includes a first guide portion 410 and a second guide portion 420. The first guide portion 410 and the second guide portion 420 are spaced apart and opposite to each other along a first direction to form a limiting space 430 for guiding condensate. The two ends of the limiting space 430 are respectively corresponding to the condensate outlet 20 and the guide rib 30. The first guide portion 410 and the second guide portion 420 both extend from the condensate outlet 20 to the guide rib 30 so that the condensate flowing out of the condensate outlet 20 flows onto the guide rib 30.

[0051] As can be seen, the rear cylinder component of this application includes a flow guiding structure disposed between the condensate outlet 20 and the guide rib 30. The flow guiding structure is provided with a first guide portion 410 and a second guide portion 420 spaced apart along a first direction to form a limiting space 430 for guiding the condensate. This ensures that the condensate will not deviate from the ideal flow path due to structural changes inside the rear cylinder, such as mold seams or vibrations. This allows the condensate to flow more smoothly and evenly onto the guide rib 30, increasing the contact area and time between the condensate and the hot, humid air, thereby significantly improving the condensation efficiency. Regarding efficiency and drying effect, this application limits the flow range of condensate water, preventing condensate water from splashing into the inner drum and wetting clothes due to changes in the water path. This reduces the possibility of clothes getting accidentally soaked during the drying process, improving the user experience. Furthermore, the use of the flow guiding structure allows condensate water to more accurately cover the inner surface of the rear drum, facilitating more effective exchange with hot and humid air, promoting the condensation of moisture in the air, and accelerating the drying process of clothes. This effectively solves the problem in existing washer-dryers where condensate water on the rear drum deviates from its intended flow direction during operation.
