Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a drying structure for a cleaning machine and a cleaning machine. Background Technology

[0002] In the field of cleaning equipment technology, the core of the drying function lies in whether the airflow can efficiently cover the parts to be cleaned within the cleaning chamber. The layout of the air inlet in the inner tank directly determines the initial flow state of the airflow and plays a crucial role in the drying effect. In the drying structure of some existing cleaning machines, the air inlet in the inner tank is often located near the symmetrical center of the inner tank. After the airflow enters the cleaning chamber, it tends to rise directly to the top opening of the inner tank, making it difficult to form an orderly flow within the chamber. This results in insufficient contact between the parts to be cleaned and the airflow, especially in scenarios lacking auxiliary airflow guiding structures. Consequently, the drying efficiency is low, and localized incomplete drying is likely to occur, affecting the overall drying quality. Utility Model Content

[0003] Therefore, it is necessary to provide a cleaning machine drying structure and cleaning machine to address the problem that improper layout of the inner tank air inlet in the existing cleaning machine drying structure leads to airflow going straight up and insufficient contact of the parts to be cleaned with airflow.

[0004] A drying structure for a washing machine includes: an inner liner assembly, the inner liner assembly including an inner liner body, the inner liner body having a washing chamber, and an inner liner air inlet communicating with the washing chamber on a first side wall of the inner liner body, the inner liner air inlet being located on one side of the vertical central axis of the first side wall; and an air duct assembly, the air duct assembly being disposed within the washing chamber, the air duct assembly having an air guide chamber, and the air duct assembly having an air duct inlet and an air outlet communicating with the air guide chamber, the air duct inlet being adjacent to and communicating with the inner liner air inlet.

[0005] The aforementioned drying structure of the washing machine features a cleaning chamber within the inner liner assembly. This chamber provides a stable support space for the parts to be cleaned, serving as the fundamental carrier for the drying function. The air inlet on the first side wall of the inner liner assembly is positioned on one side of the vertical central axis, ensuring an asymmetrical initial flow direction when the airflow enters the cleaning chamber. This prevents the airflow from leaving the cleaning chamber directly from the center, increasing the flow path of hot air within the chamber, thus expanding the drying area and extending the drying time. The air duct inlet of the air duct assembly is adjacent to and connected to the inner liner air inlet, ensuring that externally input drying airflow can quickly enter the air guide cavity through both.

[0006] In one embodiment, the inner liner assembly further includes a guide vane disposed at the air inlet of the inner liner. The end of the guide vane near the cleaning chamber is inclined towards the vertical central axis away from the first sidewall. Without the guide vane, the air inlet of the inner liner would not flow towards other sidewalls, resulting in poor drying at the edges of the cleaning chamber. In this structure, the guide vane guides the airflow to spiral upwards along the sidewall of the inner liner body, with the center of the inner liner body as the axis, to the top of the inner liner body, forming a tornado-like effect. This reduces dead air zones within the inner liner body and prolongs the airflow time within the inner liner body, thereby achieving a better drying effect.

[0007] In one embodiment, the number of guide vanes is multiple, and the multiple guide vanes are arranged side by side at intervals at the air inlet of the inner liner. By setting multiple side by side at intervals at the air inlet of the inner liner, the airflow guiding effect can be further optimized; the multiple spaced guide vanes can evenly distribute the airflow entering the cleaning chamber, so that the airflow can obtain a stable spiral upward guidance at different positions, avoiding the problem of uneven airflow distribution under the guidance of a single guide vane, further reducing the dead airflow angles in the inner liner body, ensuring that the parts to be cleaned in different areas of the cleaning chamber can fully contact the airflow, and improving the overall drying consistency.

[0008] In one embodiment, the inner liner assembly has a top opening on one side, and the inner liner air inlet is located at the end of the first sidewall away from the top opening. The inner liner air inlet is positioned at the end of the first sidewall away from the top opening, which is the lower region of the cleaning chamber, conforming to the reasonable path of "airflow from bottom to top" during the drying process. The externally input drying airflow is mostly hot air, naturally exhibiting an upward flow tendency. After entering from the bottom, it can gradually diffuse upwards using its own flow characteristics, completely covering all space within the cleaning chamber from bottom to top, ensuring that items placed at different heights are fully utilized by the airflow. Simultaneously, this layout avoids the airflow entering from the top and directly impacting downwards, preventing an imbalance where airflow accumulates at the bottom and weakens at the top, thus providing an initial path guarantee for subsequent orderly airflow and uniform drying.

[0009] In one embodiment, the inner liner air inlet is located on the side of the first sidewall away from its vertical central axis. This offset of the inner liner air inlet from the vertical central axis of the first sidewall creates an "off-center" initial flow direction when the airflow enters the cleaning chamber, preventing airflow from directly impacting the central area of ​​the cleaning chamber and causing airflow collisions and turbulence. This off-center input method can synergize with the airflow guiding function of the duct assembly within the cleaning chamber. The airflow guiding cavity of the duct assembly can further regulate this off-center airflow, creating a more stable flow trajectory, such as a circumferential flow, reducing airflow stagnation and loss in the central area, improving the airflow efficiency within the cleaning chamber, and creating conditions for sufficient contact between the subsequent airflow and the parts to be cleaned.

[0010] In one embodiment, the inner liner air inlet and the duct air inlet are arranged opposite to each other; on the projection along the thickness direction of the first sidewall, the inner liner air inlet and the duct air inlet do not overlap at least partially. This design, where the inner liner air inlet and the duct air inlet are opposite, minimizes the airflow path from the inner liner assembly to the duct assembly, reduces airflow resistance at their junction, and allows airflow to quickly enter the air guide cavity in a straight line. This ensures stable airflow and uniform velocity entering the duct assembly, providing a sufficient and high-quality airflow source for subsequent regularized airflow in the air guide cavity and stable airflow output from the outlet. Simultaneously, the design that the inner liner air inlet and the duct air inlet do not overlap at least partially ensures that part of the airflow output from the inner liner air inlet is delivered to the duct air inlet, and part is directly delivered to the cleaning chamber, guaranteeing the efficiency and comprehensiveness of the overall airflow delivery process.

[0011] In one embodiment, the drying structure of the cleaning machine includes a spray assembly disposed on the air duct assembly. The spray assembly has a guide cavity and an inlet and a spray nozzle communicating with the guide cavity. The spray direction of the spray nozzle is consistent with the air outlet direction. The drying structure also includes a support assembly disposed on the air duct assembly, with the support direction consistent with the air outlet direction. The integrated arrangement of the spray assembly and the air duct assembly, with the spray direction aligned with the air outlet direction, achieves synergistic cleaning and drying functions. During the cleaning stage, the liquid sprayed from the spray nozzle can be enhanced with the airflow from the air outlet to increase coverage, ensuring that the liquid adheres evenly to the surface of the item to be cleaned. During the drying stage, the airflow can directly act on the residual liquid on the surface of the item to be cleaned, accelerating water vapor evaporation and carrying it away in time, preventing secondary condensation of water vapor on the surface of the item, and improving drying efficiency. The integration of the support assembly and the air duct assembly, with the support direction aligned with the air outlet direction, provides stable support for the item to be cleaned while preventing the support structure from obstructing the airflow path. After the items to be cleaned are fixed by the support components, the airflow can smoothly pass through the surface of the items along the support direction, completing the water vapor exchange without obstruction, which ensures the reliability of the support and does not affect the drying effect.

[0012] In one embodiment, the air duct assembly includes an air guide housing, an air inlet pipe, and an air outlet pipe. The air guide housing has air guide chambers distributed along its extension direction. The air inlet pipe is disposed on the air guide housing and has an air inlet. The air outlet pipe is disposed on the air guide housing and has an air outlet. The spray assembly and the support assembly are both disposed on the air guide housing. The air guide chambers of the air guide housing are distributed along the extension direction, which allows the airflow entering from the air inlet pipe to be evenly distributed within the air guide chamber along the extension direction of the housing, avoiding airflow concentration in local areas and resulting in uneven airflow output from the air outlet pipe. The air outlet pipe, as the airflow output end, can directionally deliver the regulated airflow to the target area within the cleaning chamber, ensuring the precision of the airflow action. Simultaneously, the spray assembly and the support assembly are both integrated on the air guide housing, forming a three-in-one integrated structure. This layout not only saves space inside the cleaning chamber and avoids wasted space due to the scattered placement of components, but also ensures the functional coordination of the three components. The airflow output direction of the air guide housing, the spray direction of the spray component, and the support direction of the support component can be kept consistent, avoiding functional interference caused by misalignment of components.

[0013] In one embodiment, an air outlet is provided on the side of the air guide housing away from the air outlet pipe. The air outlet is located at the end of the air guide housing away from the air inlet pipe. Multiple air outlets are spaced apart along the extension direction of the air guide housing and communicate with the air guide cavity. Air outlet pipes and air outlets are respectively provided on both sides of the air guide housing, forming a bidirectional air outlet layout that works in conjunction with the airflow delivery path of the air guide cavity. After the airflow enters the air guide cavity from the air inlet pipe, part of it is output through the air outlet pipe, and the other part is discharged through the air outlet. The two form complementary airflow coverage, filling the coverage blind spots of a single air outlet direction. Multiple air outlets spaced apart along the extension direction of the air guide housing ensure that the airflow is evenly distributed along the length of the housing, avoiding insufficient local airflow and improving the integrity and uniformity of the overall drying effect.

[0014] In one embodiment, the air guide housing is annular, the spray assembly is disposed on the inner side of the air guide housing, and the support assembly is disposed on the outer side of the air guide housing. The spray assembly includes a flow guide housing, flow guide arms, and spray pipes. Multiple flow guide arms are disposed on the air guide housing and are spaced apart circumferentially along the inner side of the air guide housing. The flow guide housing is disposed on and connects all the flow guide arms, forming the flow guide cavity with the flow guide arms. The flow guide housing has a liquid inlet. Multiple spray pipes are disposed on the flow guide housing and / or the flow guide arms, and each spray pipe has a spray nozzle. The spray assembly is disposed on the inner side of the annular air guide housing, and the support assembly is disposed on the outer side. The annular structure achieves functional zoning of the inner and outer sides, ensuring that the two do not interfere with each other. Multiple guide arms are spaced circumferentially along the inner side of the air guide housing, providing stable support for the housing and forming a guide cavity to ensure smooth and even distribution of the liquid entering through the inlet. Multiple spray pipes are distributed on the air guide housing and / or the guide arms, allowing liquid to be sprayed onto the workpiece from different positions, ensuring uniform spray coverage. Simultaneously, the airflow output from the annular air guide housing, the spraying action of the spray assembly, and the supporting function of the support assembly work together to enhance the synergy of each function during the cleaning and drying process, thus improving the overall effect.

[0015] In one embodiment, the drying structure of the washing machine further includes a cylindrical support frame disposed on the spray assembly, the support direction of which is consistent with the support direction of the support assembly. The cylindrical support frame, disposed on the spray assembly, serves as a placement structure for items to be washed, providing additional placement space. Its support direction aligns with the support assembly, creating a coordinated placement layout and enriching the ways items can be placed within the washing chamber. Simultaneously, the cylindrical structure does not significantly obstruct the airflow path, and its support direction aligns with the air outlet direction, ensuring smooth airflow to the items placed on it, thus expanding the placement space without compromising the drying effect.

[0016] The second aspect of this application discloses a cleaning machine, which includes the aforementioned cleaning machine drying structure.

[0017] The aforementioned cleaning machine achieves a comprehensive effect through the rational air intake layout of the inner tank components, the precise air guidance of the air duct components, the integrated coordination of the spray and support components, and the functional supplementation of various sub-structures such as guide vanes, air outlets, and column support frames. This results in orderly airflow, comprehensive coverage, coordinated cleaning and drying, and stable and reliable support. This integrated design effectively improves the cleaning machine's adaptability to different types of items to be cleaned, reduces residual moisture after drying, shortens drying time, and reduces the probability of functional interference between components, thereby improving the cleaning machine's operational stability and user experience.

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] The following describes the drying structure of the cleaning machine and the cleaning machine according to some embodiments of the present invention with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1 to 9 As shown, this embodiment discloses a drying structure for a washing machine, including an inner liner assembly 1. The inner liner assembly 1 includes an inner liner body 11, which has a washing chamber 101. The first side wall 111 of the inner liner body 11 has an inner liner air inlet 102 that communicates with the washing chamber 101. The inner liner air inlet 102 is located on one side of the vertical central axis of the first side wall 111, that is, the inner liner air inlet 102 is offset from the vertical central axis. An air duct assembly 2 is disposed in the washing chamber 101. The air duct assembly 2 has an air guide chamber 201 and an air duct air inlet 202 and an air outlet 203 that communicate with the air guide chamber 201. The air duct air inlet 202 is adjacent to and communicates with the inner liner air inlet 102.

[0038] The drying structure of the cleaning machine disclosed in this application provides a stable bearing space for the parts to be cleaned within the inner tank body 11 of the inner tank assembly 1, serving as the basic carrier for the drying function. The inner tank air inlet 102 on the first side wall 111 of the inner tank body 11 is located on one side of the vertical central axis, giving the airflow an asymmetrical initial flow direction when entering the cleaning chamber 101. This prevents the airflow from leaving the cleaning chamber 101 directly from the central area, increasing the flow path of hot air within the cleaning chamber 101, thus increasing the drying area and extending the drying time. The air duct inlet 202 of the air duct assembly 2 is adjacent to and connected to the inner tank air inlet 102, ensuring that the externally input drying airflow can quickly enter the air guide cavity 201 through both.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner liner assembly 1 also includes a guide vane 12, which is disposed at the inner liner air inlet 102. The end of the guide vane 12 near the cleaning chamber 101 is inclined in a direction away from the vertical central axis of the first side wall 111. Without the guide vane 12, the air inlet 102 of the inner liner will not flow towards other side walls, resulting in poor drying effect at the edge of the cleaning chamber 101. In this structure, the guide vane 12 can guide the airflow to spiral upward along the side wall of the inner liner body 11 with the center of the inner liner body 11 as the axis, forming a tornado-like effect. This can reduce the dead air angles in the inner liner body 11 and prolong the airflow time in the inner liner body 11, thereby achieving a better drying effect.

[0040] In addition to the features of the above embodiments, this embodiment further specifies that: the number of guide vanes 12 is multiple, and the multiple guide vanes 12 are arranged side by side at intervals at the air inlet 102 of the inner liner. By setting multiple side by side at intervals at the air inlet 102 of the inner liner, the airflow guiding effect can be further optimized; the multiple spaced guide vanes 12 can evenly distribute the airflow entering the cleaning chamber 101, so that the airflow can obtain a stable spiral upward guidance at different positions, avoiding the problem of uneven airflow distribution under the guidance of a single guide vane 12, further reducing the dead zones of airflow in the inner liner body 11, ensuring that the parts to be cleaned in different areas of the cleaning chamber 101 can fully contact the airflow, and improving the overall drying consistency.

[0041] In addition to the features of the above embodiments, this embodiment further specifies that: one side of the inner liner assembly 1 has a top opening 103, and the inner liner air inlet 102 is located at the end of the first side wall 111 away from the top opening 103. The inner liner air inlet 102 is located at the end of the first side wall 111 away from the top opening 103, which is the lower region of the cleaning chamber 101, conforming to the reasonable path of "airflow from bottom to top" during the drying process. The externally input drying airflow is mostly hot airflow, which naturally has an upward flow tendency. After entering from the bottom, it can gradually diffuse upward with the help of its own flow characteristics, and can completely cover all the space in the cleaning chamber 101 from bottom to top, ensuring that the items to be cleaned placed at different heights can be fully utilized by the airflow. At the same time, this layout can avoid the airflow entering from the top and directly impacting downward, causing an imbalance problem of airflow accumulation at the bottom and weak airflow at the top, providing an initial path guarantee for the subsequent orderly flow of airflow and uniform drying.

[0042] The inner liner air inlet 102 is located below the first side wall 111. Specifically, the distance between the inner liner air inlet 102 and the bottom edge of the first side wall 111 is 2cm to 10cm.

[0043] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the inner liner air inlet 102 is located on the side of the first sidewall 111 away from its vertical central axis. The inner liner air inlet 102 deviates from the vertical central axis of the first sidewall 111, causing the airflow to form an "off-center" initial flow direction when entering the cleaning chamber 101, avoiding airflow collisions and turbulence caused by the airflow directly rushing towards the central area of ​​the cleaning chamber 101. This off-center input method can synergize with the airflow guiding function of the air duct assembly 2 within the cleaning chamber 101. The airflow guiding cavity 201 of the air duct assembly 2 can further regulate this deviated airflow, making it form a more stable flow trajectory, such as a circumferential flow, reducing airflow stagnation and loss in the central area, improving the airflow efficiency within the cleaning chamber 101, and creating conditions for sufficient contact between the subsequent airflow and the item to be cleaned.

[0044] The distance between the inner liner air inlet 102 and the side edge of the first side wall 111 is 2cm to 5cm, so that it is as far away as possible from the vertical central axis of the first side wall 111.

[0045] like Figure 2 , Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner liner air inlet 102 and the air duct air inlet 202 are arranged opposite to each other; on the projection along the thickness direction of the first sidewall 111, the inner liner air inlet 102 and the air duct air inlet 202 do not overlap at least partially. The design of the inner liner air inlet 102 and the air duct air inlet 202 facing each other can minimize the airflow path from the inner liner assembly 1 to the air duct assembly 2, reduce the flow resistance at the junction of the two, and allow the airflow to enter the air guide cavity 201 quickly in a straight line, ensuring a stable airflow and uniform flow rate into the air duct assembly 2. This provides a sufficient and high-quality airflow source for the subsequent regular airflow in the air guide cavity 201 and the stable output airflow from the air outlet 203. At the same time, the design of the inner liner air inlet 102 and the air duct air inlet 202 not overlapping at least partially ensures that part of the airflow output from the inner liner air inlet 102 is delivered to the air duct air inlet 202 and part is delivered directly to the cleaning chamber 101, ensuring the efficiency and comprehensiveness of the overall airflow delivery process.

[0046] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the drying structure of the cleaning machine includes a spray assembly 3, which is disposed on the air duct assembly 2. The spray assembly 3 has a guide cavity 301 and has an inlet 302 and a spray nozzle 303 communicating with the guide cavity 301. The spraying direction of the spray nozzle 303 is consistent with the air outlet direction of the outlet 203. The drying structure of the cleaning machine includes a support assembly 4, which is disposed on the air duct assembly 2. The support direction of the support assembly 4 is consistent with the air outlet direction of the outlet 203. The integrated arrangement of the spray assembly 3 and the air duct assembly 2, with the spraying direction consistent with the air outlet direction, achieves the synergistic function of cleaning and drying. During the cleaning stage, the liquid sprayed from the spray nozzle 303 can enhance the coverage area with the help of the airflow from the outlet 203, ensuring that the liquid is evenly attached to the surface of the part to be cleaned. During the drying stage, the airflow can directly act on the residual liquid on the surface of the part to be cleaned, accelerating the evaporation of water vapor and carrying it away in time, avoiding secondary condensation of water vapor on the surface of the item, and improving the drying efficiency. The support component 4 is integrated with the air duct component 2, and the support direction is consistent with the air outlet direction. This ensures stable support for the items to be cleaned while preventing the support structure from obstructing the airflow path. After the items to be cleaned are fixed by the support component 4, the airflow can smoothly pass through the surface of the items along the support direction, completing the water vapor exchange without obstruction. This ensures the reliability of the support without affecting the drying effect.

[0047] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines: the air duct assembly 2 includes an air guide housing 21, an air inlet pipe 22, and an air outlet pipe 23. The air guide housing 21 is provided with an air guide cavity 201, which is distributed along the extension direction of the air guide housing 21. The air inlet pipe 22 is disposed on the air guide housing 21 and has an air inlet 202. The air outlet pipe 23 is disposed on the air guide housing 21 and has an air outlet 203. The spray assembly 3 and the support assembly 4 are both disposed on the air guide housing 21. The air guide cavity 201 of the air guide housing 21 is distributed along the extension direction, which allows the airflow entering from the air inlet pipe 22 to be evenly distributed in the air guide cavity along the extension direction of the housing, avoiding the airflow from concentrating in a local area and causing uneven airflow output from the air outlet pipe 23. The air outlet pipe 23, as the airflow output end, can directionally deliver the regulated airflow to the target area in the cleaning chamber 101, ensuring the accuracy of the airflow action. Meanwhile, the spray assembly 3 and the support assembly 4 are both integrated on the air guide housing 21, forming a three-in-one integrated structure. This layout not only saves internal space in the cleaning chamber 101 and avoids space waste caused by the scattered placement of each component, but also ensures the functional coordination of the three components. The airflow output direction of the air guide housing 21, the spray direction of the spray assembly 3, and the support direction of the support assembly 4 can be kept consistent, avoiding functional interference caused by misalignment of components.

[0048] like Figure 6 , Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: an air outlet 2101 is provided on the side of the air guide housing 21 away from the air outlet pipe 23, the air outlet 2101 is located at the end of the air guide housing 21 away from the air inlet pipe 22, and there are multiple air outlets 2101, which are spaced apart along the extension direction of the air guide housing 21, and the air outlets 2101 are connected to the air guide cavity 201. Air outlet pipes 23 and air outlets 2101 are respectively provided on both sides of the air guide housing 21, forming a bidirectional air outlet layout, which works in conjunction with the airflow delivery path of the air guide cavity 201. After the airflow enters the air guide cavity 201 from the air inlet pipe 22, part of it is output through the air outlet pipe 23, and the other part is discharged through the air outlet 2101, forming a complementary airflow coverage, filling the coverage blind spot of a single air outlet direction. Multiple air outlets 2101 spaced apart along the extension direction of the air guide housing 21 ensure that the airflow is evenly distributed along the length of the housing, avoid insufficient local airflow, and improve the integrity and uniformity of the overall drying effect.

[0049] like Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the air guide housing 21 is annular, the spray assembly 3 is disposed on the inner side of the air guide housing 21, and the support assembly 4 is disposed on the outer side of the air guide housing 21; the spray assembly 3 includes a flow guide housing 31, a flow guide arm 32, and a spray pipe 33, the flow guide arm 32 is disposed on the air guide housing 21, and there are multiple flow guide arms 32, which are spaced apart circumferentially along the inner side of the air guide housing 21; the flow guide housing 31 is disposed on the flow guide arm 32 and connects all the flow guide arms 32, the flow guide housing 31 and the flow guide arm 32 cooperate to form a flow guide cavity 301, the flow guide housing 31 has a liquid inlet 302, and there are multiple spray pipes 33, which are disposed on the flow guide housing 31 and / or the flow guide arm 32, and the spray pipes 33 have spray nozzles 303. The annular air guide housing 21 has a spray assembly 3 on its inner side and a support assembly 4 on its outer side. The annular structure achieves functional zoning of the inner and outer sides, ensuring that the two do not interfere with each other. Multiple guide arms 32 are distributed circumferentially along the inner side of the air guide housing 21, providing stable support for the housing and forming a guide cavity 301 with it. This allows the liquid entering through the inlet 302 to flow smoothly and be evenly distributed along the guide cavity. Multiple spray pipes 33 are distributed on the guide housing 31 and / or the guide arms 32, spraying liquid onto the workpiece from different positions to ensure uniform spray coverage. Simultaneously, the airflow output from the annular air guide housing 21, the spraying action of the spray assembly 3, and the supporting function of the support assembly 4 work together to enhance the synergy of the various functions during the cleaning and drying process, improving the overall effect.

[0050] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the drying structure of the washing machine also includes a columnar support frame 5, which is disposed on the spray assembly 3, and the support direction of the columnar support frame 5 is consistent with the support direction of the support assembly 4. The columnar support frame 5, disposed on the spray assembly 3, can serve as a placement structure for items to be cleaned, providing additional placement space for the items. Its support direction is consistent with the support assembly 4, forming a coordinated placement layout with the support assembly 4, enriching the ways items can be placed within the washing chamber. Simultaneously, the columnar structure does not significantly obstruct the airflow path, and its support direction is consistent with the air outlet 203's airflow direction, ensuring that the airflow can smoothly act on the items placed on it, thus expanding the item placement space without affecting the drying effect.

[0051] Example 2

[0052] like Figures 1 to 9 As shown in the figure, this embodiment discloses a cleaning machine, including a cleaning machine drying structure.

[0053] The cleaning machine disclosed in this application achieves a comprehensive effect of orderly airflow, comprehensive coverage, coordinated cleaning and drying, and stable and reliable support through the rational air intake layout of the inner tank assembly, the precise air guidance of the air duct assembly, the integrated coordination of the spray and support components, and the functional supplementation of various sub-structures such as guide vanes, air outlets, and column support frames. This integrated design effectively improves the adaptability of the cleaning machine to different types of parts to be cleaned, reduces residual moisture after drying, shortens drying time, and reduces the probability of functional interference between components, thereby improving the operational stability and user experience of the cleaning machine.
