Description

Technical Field

[0001] The present invention relates to the field of washing, in particular to a wall-mounted washing device. Background Art

[0002] As living standards improve, personalized home appliances are increasingly becoming popular. Wall-mounted washing machines, such as drum washing machines, are increasingly popular due to their compact structure, minimal footprint, low noise, and low cost. For example, some wall-mounted washing machines can be used to wash small intimate apparel or infant clothing. This not only allows for lightweight laundry but also prevents cross-contamination of bacteria between garments, offering excellent value for money and practicality.

[0003] To provide more functionality, wall-mounted washing machines with drying functions have been developed in the prior art. For example, Chinese invention patent application CN111809339A discloses a wall-mounted washing machine. This wall-mounted washing machine includes an outer drum and a drying device, at least partially integrally formed on the sidewall of the outer drum. The drying device includes a first air duct and a second air duct. The first air duct communicates with the air inlet of the outer drum to deliver hot and dry air into the interior of the outer drum, and the second air duct communicates with the air outlet of the outer drum and the first air duct, respectively, to condense the hot and humid air received from the outer drum into dry and cold air in the second air duct. However, the overall size of wall-mounted washing machines is relatively small, and the internal space is limited, resulting in a smaller second air duct. The condensation effect of the hot and humid air in the second air duct is poor, resulting in a higher humidity in the air entering the first air duct. This not only reduces the heating efficiency of the heating element in the first air duct and increases energy consumption, but also reduces the ability of the dry air with excessive humidity to remove moisture from the items to be dried (such as clothes, shoes, hats, etc.), greatly reducing the drying efficiency.

[0004] To improve the condensation efficiency of the condensing assembly, a wall-mounted washing machine with a spray device has been developed in the prior art. For example, Chinese invention patent CN107299486B discloses a washing machine drum and a drum washing machine. The washing machine drum includes an outer drum and a condensation channel. A spray port for connecting to the spray device is provided at the upper portion of the condensation channel, and a plurality of condensation fins arranged in a staggered manner to form a flow gap are provided on the inner wall surface of the condensation channel. Condensed water enters the condensation channel through the spray port and flows from the upper condensation fin to the lower condensation fin among the adjacent condensation fins, thereby increasing the flow length and flow time of the condensation water in the condensation channel. This in turn increases the contact area and contact time between the condensation water sprayed in from the spray port and the water vapor entering from the inner drum of the washing machine, thereby improving drying efficiency. However, the staggered arrangement of the multiple condensation fins in the washing machine drum within the condensation channel significantly increases the wind resistance of the air in the condensation channel, greatly reducing the air supply efficiency within the condensation channel. In addition, after the condensed water enters the condensation channel from the spray port, it flows in sequence along multiple staggered condensation plates. Its movement trajectory is relatively regular, the contact area between the condensed water and the hot and humid air is limited, and the condensation efficiency is low. Therefore, there is a possibility of improvement in the washing machine drum.

[0005] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0006] In order to solve the technical problem of low condensation efficiency of a condensation assembly in a wall-mounted washing device in the prior art, the present invention provides a wall-mounted washing device. The wall-mounted washing device includes an outer drum and a condensation assembly, wherein the condensation assembly includes: an air duct body, the air duct body being arranged on the side wall of the outer drum and extending in a vertical direction; an air duct cover, the air duct cover being configured to be detachably fixed to the air duct body and to form a closed condensation chamber with the air duct body, a liquid outlet being provided on the inner wall of the air duct cover, and a baffle and a plurality of guide plates located below the liquid outlet and spaced apart from each other to form a guide port being formed on the inner wall, wherein the baffle is configured and positioned to change the flow direction of liquid entering the condensation chamber from the liquid outlet and to guide the liquid onto the plurality of guide plates so that at least part of the liquid can flow out from the guide port.

[0007] Those skilled in the art will appreciate that the wall-mounted washing device of the present invention includes an outer drum and a condensation assembly. The condensation assembly includes a duct body and a duct cover. The duct body is arranged on the side wall of the outer drum and extends in a vertical direction. The duct cover is removably fixed to the duct body and, together with the duct body, forms a closed condensation chamber. It will be understood that the duct body is arranged to extend in a vertical direction, so that the condensation chamber also extends approximately in a vertical direction. After the hot and humid air is converted into dry and cold air and condensed water, the condensed water can be easily discharged from the condensation chamber under the action of its own gravity. In addition, the duct cover is arranged to be removably fixed to the duct body. This not only facilitates manufacturing by allowing the duct cover and the duct body to be processed separately, but also facilitates cleaning, maintenance, and repair of the condensation chamber after the duct cover is removed. A liquid outlet is provided on the inner wall of the duct cover, and a plurality of guide plates are provided below the liquid outlet, spaced apart from each other, with guide ports formed between adjacent guide plates. The baffle is configured and positioned to change the flow direction of the liquid (such as condensed water) entering the condensation chamber from the liquid outlet, and to guide the liquid to a plurality of guide plates so that at least part of the liquid flows out from the guide port. It is understandable that after the liquid flows into the condensation chamber from the liquid outlet, at least most of it will hit the baffle and be changed to flow toward the guide plate. Through the cooperation of the baffle and the plurality of guide plates, the liquid is directed to the plurality of guide plates. Part of the liquid is broken up when it hits the plurality of guide plates, thereby diffusing into the condensation chamber, and the contact probability and contact area of ​​the dispersed liquid with the hot and humid air are significantly increased, thereby improving the condensation efficiency of the condensation assembly. In addition, part of the liquid flows out from the guide port arranged between adjacent guide plates, so that the dispersion of the liquid is increased, and the distribution of the liquid in the condensation chamber is more uniform, further improving the condensation efficiency.

[0008] In the preferred technical solution of the above-mentioned wall-mounted washing device, a joint pipe integrally formed with the air duct cover is provided on the air duct cover, and the joint pipe has a liquid inlet end that can be connected to the liquid pipe and a liquid outlet end that is connected to the liquid outlet so as to introduce the liquid into the condensation chamber. The joint pipe is configured to be integrally formed with the air duct cover, which not only simplifies the manufacturing process and facilitates processing, but also avoids opening holes in the air duct cover, preventing air from flowing out of the holes, affecting the air supply efficiency, and generating noise. The joint pipe has a liquid inlet end and a liquid outlet end, the liquid inlet end can be connected to the liquid pipe, and the liquid outlet end is connected to the liquid outlet so as to introduce the liquid in the liquid pipe into the condensation chamber.

[0009] In the preferred technical solution of the above-mentioned wall-mounted washing device, the joint pipe is configured to extend horizontally or obliquely downward from the liquid inlet end along its own center line to the inner wall, so that the center line forms a first predetermined angle α with its vertical projection line on the air duct cover, and the vertical projection line forms a second predetermined angle β with the length direction of the air duct cover, and the range of the first predetermined angle α is 5°-10°, and the range of the second predetermined angle β is 0°-10°. The center line of the joint pipe forms a first predetermined angle α with its vertical projection line on the air duct cover, that is, the center line of the joint pipe forms a first predetermined angle α with the plane where the air duct cover is located, so that the joint pipe and the air duct cover are easy to process when they are integrally formed. In addition, the joint pipe extends horizontally or obliquely downward from the liquid inlet end along its own center line to the inner wall of the air duct cover, so that the joint pipe extends roughly along the length direction of the air duct cover, which is beneficial to the pipeline arrangement when the liquid pipe is connected to the joint pipe, making the internal structure of the wall-mounted washing device more compact. Furthermore, the joint pipe is arranged to extend generally along the length of the air duct cover, so that the initial flow direction of the liquid introduced into the condensation chamber through the joint pipe can also extend generally in the horizontal direction. Under the action of gravity, the liquid moves generally in a parabolic motion, which makes the liquid tend to disperse in the vertical direction, thereby facilitating further dispersion of the liquid.

[0010] In the preferred technical solution of the above-mentioned wall-mounted washing equipment, the baffle is configured as an arc-shaped plate close to the liquid outlet and protruding toward the liquid outlet, and the center line extends through the arc-shaped plate. The baffle is configured close to the liquid outlet so that the liquid sprayed from the liquid outlet can easily impact the baffle. The arrangement of the arc-shaped plate enables the baffle to have a larger radial surface area, the probability of contact between the liquid and the arc-shaped plate is increased, and the utilization rate of the baffle is increased. Furthermore, the arc-shaped plate is configured to protrude in the direction of the liquid outlet, so that the liquid is reflected when it contacts the radial outer surface of the arc-shaped plate, the range of flow direction change is increased, and the liquid is dispersed more evenly. In addition, the center line of the joint pipe is configured to extend through the arc-shaped plate, which can ensure that the position of the baffle does not deviate from the flow direction of the liquid, further improving the effectiveness of the baffle in guiding the liquid.

[0011] In the preferred technical solution of the above-mentioned wall-mounted washing machine, the curved plate is configured to extend vertically outward from the inner wall to a first predetermined height H1, with the first predetermined height H1 ranging from 12mm to 15mm. This configuration ensures that the curved plate has a moderate height, effectively guiding and redirecting liquid flow while preventing excessive height from increasing wind resistance and affecting air supply efficiency.

[0012] In the preferred technical solution of the above-mentioned wall-mounted washing device, the inner diameter of the joint pipe is d, and the radial deflection outer arc surface of the arc plate has a first radius R1 and a first curvature θ1, wherein R1 = (3-5) × d, and the range of the first curvature θ1 is 0.5rad-1rad. Through the above-mentioned configuration, the radial outer arc surface of the arc plate has a moderate arc length and curvature, which can effectively guide the liquid and change its flow direction while preventing the arc length from being too large, which will increase the wind resistance and affect the air supply efficiency. It can also avoid the arc being too large, which will cause part of the arc plate to not contact the liquid and play a role in guiding the liquid, thereby reducing the utilization rate of the entire arc plate.

[0013] In the preferred technical solution of the above-mentioned wall-mounted washing machine, the radially deflecting outer arc surface intersects the inner wall to form an outer arc line. The tangent of the outer arc line at its upper vertical endpoint forms a third predetermined angle γ with the vertical projection line. The third predetermined angle γ ranges from 15° to 25°. Through the above configuration, the third predetermined angle γ between the tangent of the outer arc line at its upper endpoint and the vertical projection line is within a moderate range, thereby maintaining a relatively fixed position of the curved plate along its circumference, thereby achieving a better diversion effect.

[0014] In the preferred technical solution of the above-mentioned wall-mounted washing machine, each deflector is configured to extend vertically outward from the inner wall to a second predetermined height H2, and the second predetermined height H2 ranges from 8mm to 10mm. This configuration ensures that each deflector has an appropriate height, preventing the deflector from being too low and thus failing to disperse the liquid, and also preventing the deflector from being too high and thus increasing wind resistance and affecting air supply efficiency.

[0015] In the preferred technical solution of the above-mentioned wall-mounted washing device, each of the guide plates is configured as an arc-shaped guide plate, and all of the arc-shaped guide plates together form a radial guide outer arc surface that bulges in a direction away from the liquid outlet, and the radial guide outer arc surface has a second radius R2 and a second radian θ2, wherein R2 = (2-3.2) × d, and the second radian θ2 ranges from 2.4 rad to 3.14 rad. The guide plates are configured as arc-shaped guide plates, and all of the arc-shaped guide plates together form a radial guide outer arc surface that bulges in a direction away from the liquid outlet, so that the guide plates have a larger radial surface area, the probability of liquid contacting the guide plates is increased, and the effect of the guide plates in breaking up the liquid is enhanced. In addition, through the above configuration, the outer arc surface of the radial guide has a moderate arc length and curvature, which can prevent the arc length and curvature from being too large, resulting in excessive wind resistance and affecting the air supply efficiency, while preventing part of the guide plate from not contacting the liquid and failing to break up the liquid, thereby reducing the utilization rate of the guide plate.

[0016] In the preferred technical solution of the above-mentioned wall-mounted washing machine, the width of the guide opening ranges from 3mm to 5mm. This configuration ensures that the guide opening has a moderate width (i.e., the gap between adjacent guide plates). This prevents the width from being too small, which would reduce the probability of liquid flowing out of the guide opening, and also prevents the width from being too large, which would cause most of the liquid to flow directly through the guide opening without being blocked by the guide plates, thus affecting the effect of breaking up the liquid.

[0017] In the preferred technical solution of the above-mentioned wall-mounted washing machine, a solenoid valve capable of controlling the flow rate of the liquid is arranged on the liquid pipe. By setting the solenoid valve, the flow rate of the liquid entering the condensation chamber can be adjusted according to different working conditions to meet the needs under different working conditions.

Alternatively, the air duct main body 41 can also be configured to extend roughly in the vertical direction and be positioned on the left side wall of the outer cylinder 12. The air duct main body 41 is configured to extend roughly in the vertical direction so that the condensed water can be easily discharged under the action of its own gravity. Preferably, the air duct main body 41 is made of PP, ABS or other suitable resin materials through an injection molding process to form an integral body with the cylinder 12, so that the structure of the entire wall-mounted washing device 1 is more compact. Figure 2 and Figure 3 shown, and based on Figure 3In the orientation shown, the air duct body 41 includes a partially curved wall 411 formed on the right side wall 121 of the cylinder 12, an inverted L-shaped peripheral wall 412 extending to the right from the edge of the curved wall 411 in a substantially horizontal direction, and a top wall 413 formed on the top of the inverted L-shaped peripheral wall 412. A bottom inlet 416 is provided near the bottom of the curved wall 411. The bottom inlet 416 coincides with the outer cylinder air outlet 1211. A top outlet 415 is provided on the top wall 413. The top outlet 415 is configured to dock with the air intake of the fan. Figure 2 and Figure 3 As shown, the inverted L-shaped peripheral wall 412 and the top wall 413 define a lateral opening 414 extending substantially in a vertical direction.

[0040] like Figure 1 As shown, in one or more embodiments, the air duct cover 42 is configured to be detachably fixed to the air duct body 41 and can close the side opening 414. The air duct cover 42 and the air duct body 41 enclose a closed condensation chamber 43 (such as Figure 2 As shown). The fixing methods of the air duct cover 42 and the air duct main body 41 include but are not limited to screw connection, bolt connection or rivet connection. By configuring the air duct cover 42 to be detachably fixed on the air duct main body 41, the process requirements of the air duct main body 41 and the outer cylinder 10 being integrally formed can be met, and the user can also easily remove the air duct cover 42 to clean, maintain and maintain the condensation chamber 43 from the side opening 414. In one or more embodiments, the air duct cover 42 is configured to be integrally formed by an injection molding process using PP, ABS or other suitable resin materials, so as to simplify the manufacturing process and facilitate manufacturing. Preferably, a seal (not shown in the figure) is provided between the air duct cover 42 and the side opening 414, so that the air duct cover 42 can effectively seal the air duct main body 41 to prevent air from flowing out from the installation gap.

[0041] like Figure 4 As shown, the air duct cover 42 has a substantially flat plate-shaped air duct cover body 424. The air duct cover body 424 has an outer wall 421 and an inner wall 422. In one or more embodiments, a plurality of air duct cover members are formed on the outer wall 421 along the length direction (i.e., Figure 4 ) and the height direction of the air duct cover 42 (i.e. Figure 4 The reinforcement ribs 4211 extend in the up-down direction shown in FIG. The arrangement of the reinforcement ribs 4211 can increase the strength and rigidity of the air duct cover 42 to extend the service life of the air duct cover 42.

[0042] like Figure 4As shown, in one or more embodiments, a joint pipe 423 is formed at the upper portion of the outer wall 421 and close to the right side of the outer wall 421. Alternatively, the joint pipe 423 can also be arranged at the upper portion of the outer wall 421 and close to the left side of the outer wall 421. Preferably, the joint pipe 423 is made of a suitable resin material and is integrally formed with the air duct cover body through an injection molding process, which is conducive to simplifying the manufacturing process and can also avoid opening holes in the air duct cover body 424 to prevent air from flowing out of the holes, affecting the air supply efficiency and generating noise. Figure 4 As shown, the joint pipe 423 is configured as a hollow tubular structure and has a liquid inlet end 4231 and an opposite liquid outlet end 4232. Figure 1 As shown, the liquid inlet end 4231 is configured to be connected to the first end 441 of the liquid pipe 44 so as to receive the liquid transported from the liquid pipe 44. Figure 4 As shown, a liquid inlet 42311 is formed on the liquid inlet end 4231. The liquid inlet 42311 has a circular cross section, and the diameter of the liquid inlet 42311 is d (as shown in FIG. Figure 6 As shown). The diameter d ranges from 7 mm to 11 mm. Preferably, the diameter of the liquid inlet 42311 is 9 mm. Alternatively, the liquid inlet 42311 may also be configured into other suitable cross-sections, such as an elliptical shape, a semicircular shape, etc. The liquid outlet 4232 is formed on the outer wall 421 and extends along the center line C of the joint pipe 423 to the inner wall 422, so that the liquid outlet 4221 is formed on the inner wall 422. Figure 4 and Figure 5As shown, in one or more embodiments, the connector tube 423 is configured to extend obliquely downward from the liquid inlet end 4231 along the centerline C of the connector tube 423 to the outer wall 421 of the air duct cover 42, that is, the centerline C of the connector tube 423 forms a predetermined angle with the plane of the air duct cover 42. Specifically, the vertical projection line of the centerline C of the connector tube 423 on the air duct cover 42 is C1, and the centerline C and the vertical projection line C1 form a first predetermined angle α. The first predetermined angle α ranges from 5° to 10°. Through the above configuration, the connector tube 423 and the air duct cover body 424 are at a predetermined angle, which facilitates the processing and manufacturing of the connector tube 423 and the air duct cover body 424 when they are integrally formed. Furthermore, the connector tube 423 is configured to extend obliquely downward from the liquid inlet end 4231 along its centerline C to the air duct cover 42, that is, the centerline C of the connector tube 423 forms a predetermined angle with the longitudinal direction D of the air duct cover 42. Specifically, the vertical projection line C1 of the center line C of the connecting pipe 423 on the air duct cover 42 forms a second predetermined angle β with the length direction D of the air duct cover 42. The range of the second predetermined angle β is 0°<β≤10°. Alternatively, the connecting pipe 423 can also be configured to extend horizontally from the liquid inlet end 4231 along its center line C to the air duct cover 42. In this case, the second predetermined angle β is 0°. It can be understood that the connecting pipe 423 is arranged to extend horizontally or downwardly along its own center line C from the liquid inlet end 4231 to the air duct cover 42, so that the connecting pipe 423 extends roughly along the length direction D of the air duct cover 42. Therefore, when the liquid pipe 44 is connected to the connecting pipe 423, the space on the rear side of the air duct main body 41 can be utilized, which is beneficial to the pipeline arrangement and makes the internal structure of the wall-mounted washing device 1 more compact. Furthermore, the joint pipe 423 is arranged to extend generally along the length direction D of the air duct cover 42, so that the initial flow direction of the liquid introduced into the condensation chamber 43 through the joint pipe 423 can also extend generally in the horizontal direction. Under the action of gravity, the liquid moves generally in a parabolic motion, which makes the liquid tend to disperse in the vertical direction, facilitating further dispersion of the liquid.

[0043] like Figure 6 As shown, in one or more embodiments, a liquid outlet 4221 is formed at the upper portion of the inner wall 422. Liquid outlet 4221 is configured to extend generally along the centerline C of the joint pipe 423 and has a generally elliptical shape, resulting in a relatively large opening area. When liquid enters the condensation chamber 43 through liquid outlet 4221, it is strongly constrained by liquid outlet 4221, thereby enhancing its guiding effect on the liquid.

[0044] like Figure 6As shown, in one or more embodiments, a baffle 4222 is provided on the inner wall 422. The baffle 4222 is positioned near the liquid outlet 4221 so that the liquid flowing into the condensation chamber 43 from the liquid outlet 4221 can easily impact the baffle 4222 first. In one or more embodiments, the baffle 4222 is configured as a curved plate 42221 that protrudes toward the liquid outlet 4221. Compared with a straight plate, at the same transverse length (i.e., the projected length in the longitudinal direction D of the air duct cover 42), the arrangement of the curved plate 42221 has a larger radial surface area. Therefore, under the same wind resistance conditions, the probability of the liquid contacting the curved plate 42221 is greater. Alternatively, the baffle 4222 can also be configured as other suitable structures, such as a straight plate, a wavy plate, etc. In one or more embodiments, the center line C of the joint pipe 423 extends through the arc plate 42221, so that the arc plate 42221 is positioned so as not to deviate from the flow direction of the liquid, thereby improving the effectiveness of the arc plate 42221 in guiding the flow. In one or more embodiments, the arc plate 42221 is configured to extend vertically outward from the inner wall 422 to a first height H1. The first height H1 ranges from 12mm to 15mm, so that the arc plate 42221 has a moderate height, which can effectively guide the liquid while preventing the increase in wind resistance caused by excessive height, thereby affecting the air supply efficiency. The arc plate 42221 has an arc-shaped radial deflection outer arc surface 221. The center of the radial deflection outer arc surface 221 is O1, and it has a first radius R1 and a first radian θ1. Among them, the first radius R1 = (3-5) × d, and the first radian θ1 ranges from 0.5rad to 1rad. Through the above configuration, the arc plate 42221 has a moderate arc length and curvature, which can satisfy the requirement of effectively guiding the liquid and changing its flow direction, while preventing the arc length from being too long, which will increase the wind resistance and affect the air supply efficiency. It can also avoid the arc being too long, which will cause part of the arc plate 42221 to not be in contact with the liquid and thus fail to play the role of guiding the liquid, thereby reducing the utilization rate of the entire arc plate 42221. The radial deflection outer arc surface 221 intersects with the inner wall 422 to form an outer arc line 2211. The outer arc line 2211 has an upper end point 2211a in the vertical direction and an opposite lower end point 2211b. Figure 7 As described above, a tangent line E of the outer arc line 2211 passing through the upper end point 2211a forms a third predetermined angle γ with a vertical projection line C1 of the center line C of the joint pipe 423 on the air duct cover 42. The third predetermined angle γ ranges from 15° to 25°, which ensures that the position of the curved plate 42221 along its circumference is relatively fixed, thereby achieving a better air diversion effect.

[0045] like Figure 6As shown, in one or more embodiments, three deflectors 4223 are spaced apart below the liquid outlet 4221. The deflectors 4223 can disperse some of the liquid diverted by the baffles 4222, significantly increasing the contact rate and contact area between the hot and humid air and the liquid, thereby improving the condensation efficiency of the condensation assembly 40. Alternatively, the number of deflectors 4223 can be configured to be any other suitable number greater or less than three. Each deflector 4223 is configured to extend vertically outward from the inner wall 422 to a second predetermined height H2. The second predetermined height H2 ranges from 8 mm to 10 mm, ensuring that each deflector 4223 has an appropriate height. This prevents the deflector 4223 from being too small, where it fails to disperse the liquid, and prevents it from being too large, where it increases wind resistance and affects air supply efficiency. Deflector openings 4224 are formed between adjacent deflector plates 4223, including a first deflector opening 224a and a second deflector opening 224b. The setting of the guide port 4224 allows part of the liquid diverted by the deflector 4222 to flow out from the guide port 4224, increasing the dispersion of the liquid, making the distribution of the liquid in the condensation chamber 43 more uniform, and further improving the condensation efficiency. The width of each guide port 4224 ranges from 3mm to 5mm, so that the guide port 4224 has a moderate width, which can prevent the width from being too small and reducing the probability of liquid flowing out of the guide port 4224, and can also prevent the width from being too large and causing most of the liquid to flow directly through the guide port 4224 without being blocked by the guide plate 4223, affecting the effect of breaking up the liquid. Preferably, each guide port 4224 is set to the same width. Alternatively, each guide port 4224 can also be set to a different width, for example, the width of the first guide port 224a is 3mm, and the width of the second guide port 224b is 5mm, so as to obtain a richer product to meet actual needs. Figure 7 As shown, in one or more embodiments, each guide plate 4223 is arranged as an arc-shaped guide plate 42231, which is sequentially the first arc-shaped guide plate 231a, the second arc-shaped guide plate 231b and the third arc-shaped guide plate 231c, and all the arc-shaped guide plates 42231 together form a radial guide outer arc surface 4225 that is convex toward the direction away from the liquid outlet 4221. The arrangement of the arc-shaped guide plates 42231 makes the guide plates 4223 have a larger radial outer surface area, increases the contact probability between the liquid and the guide plates 4223, and enhances the effect of the guide plates 4223 in breaking up the liquid. Figure 7As shown, the center of the radial guide outer arc surface 4225 is O2, and it has a second radius R2 and a second radian θ2. Among them, the second radius R2 = (1-1.6) × d, and the range of the second radian θ2 is 2.4rad-3.14rad. Through the above configuration, the arc-shaped guide plate 42231 has a moderate arc length and radian. While meeting the requirements of effectively breaking up the liquid, it can prevent the arc length and radian from being too large, resulting in excessive wind resistance and affecting the air supply efficiency. At the same time, it can also avoid that part of the guide plate 4223 does not contact the liquid and fails to play the role of breaking up the liquid, thereby reducing the utilization rate of the guide plate 4223.

[0046] like Figure 1 As shown, in one or more embodiments, the liquid pipe 44 is configured as a hollow hose to facilitate piping layout. The liquid pipe 44 can be made of PVC, PU, ​​or other suitable materials. The liquid pipe 44 has opposing first and second ends 441 and 442. The first end 441 is configured to connect to the liquid inlet end 4231 of the connector pipe 423, and the second end 442 is configured to communicate with the output end of a solenoid valve (not shown). The solenoid valve is electrically connected to the control system of the wall-mounted washing machine 1 to adjust the flow rate of the liquid in the liquid pipe 44 by controlling the opening of the solenoid valve to meet the needs of different operating conditions. Solenoid valves include but are not limited to direct-acting solenoid valves, step-by-step direct-acting solenoid valves, and pilot-operated solenoid valves. In one or more embodiments, the input end of the solenoid valve (not shown) is connected to a condensate collection box (not shown) in the wall-mounted washing machine 1 to transport condensate through the liquid pipe 44 to the condensation chamber 43. Alternatively, the input end of the solenoid valve can be connected to other suitable liquid pipelines, such as a tap water inlet pipe.

[0047] In one or more embodiments, the wall-mounted washing device 1 further comprises a filter assembly (not shown). The filter assembly can be arranged at a suitable position in the condensation chamber 43, such as near the upper portion of the bottom inlet 416, so as to filter the hot and humid air flowing in from the bottom inlet 416, to prevent impurities such as lint from clogging the condensation chamber 43 or affecting the cleanliness in the condensation chamber 43. The filter assembly can also be arranged at a suitable position in the air supply duct 30, such as near the position of the air supply end 31, so as to filter the hot and dry air flowing in from the blower exhaust port, to prevent impurities such as lint from clogging the air supply duct 30 or flowing into the outer cylinder 10. The filter assembly has a filter (not shown), and the filter can be a metal rubber filter mesh, a nylon filter mesh, or other suitable filters. In addition, the filter assembly can also be arranged in the condensation chamber 43 and the air supply duct 30 at the same time to enhance the filtering effect.

[0048] When the wall-mounted washing machine 1 of the present invention is in the drying mode, the user can select different preset drying programs through the control system. Alternatively, various parameters of the drying process, such as drying temperature and drying time, can also be manually set to meet the user's personalized needs. When the drying function is turned on, the impeller 22 rotates, driven by the motor, drawing air from the condensation chamber 43 into the volute 21. As the air passes over the surface of the heating element 23, it is heated to form dry, hot, dry air. The dry air is guided by the air supply duct 30 and delivered into the outer drum 10 through the outer drum air inlet 1311. The dry air exchanges heat with the items to be dried in the inner drum, removing moisture from the items and converting them into moist, hot air, thereby drying the items. The moist, hot air exits the drum 12 through the outer drum air outlet 1211 located on the side wall 121 and reenters the condensation chamber 43. At this time, the solenoid valve is energized and slightly open, and the flow rate of the liquid (e.g., condensed water) in the liquid pipe 44 is relatively slow. The liquid is transported to the condensation chamber 43 through the joint pipe 423. After flowing out of the liquid outlet 4221, the liquid hits the baffle 4222 near the liquid outlet 4221, and its flow direction changes and is diverted to the guide plate 4223. Part of the liquid hits the guide plate 4223 and is broken up, and part of the liquid passes through the guide port 4224 between the spaced guide plates 4223, so that the liquid in the condensation chamber 43 is evenly dispersed. The hot and humid air is fully in contact with the liquid, so that the hot and humid air is converted into dry and cold air and condensed water. Under the action of the impeller 22, the dry and cold air is sucked into the volute 21 again, realizing the air circulation in the wall-mounted washing device 1. In addition, under the action of their own gravity, the condensed water and liquid enter the cylinder 12 from the bottom opening 416 at the bottom of the air duct main body 41 (i.e., the outer cylinder air outlet 1221), and flow along the bottom wall of the cylinder 12 to the drain port (not shown in the figure), and gather in the condensed water collection box, thereby realizing the recycling of the condensed water.

[0049] When the wall-mounted washing machine 1 of the present invention is in the cleaning mode, the solenoid valve is energized and has a wide opening, and the liquid in the liquid pipe 44 flows at a high velocity. The liquid is transported to the condensation chamber 43 through the joint pipe 423 with a large impact force. The liquid strikes the baffle 4222, causing its flow direction to change and rush toward the guide plate 4223. Part of the liquid strikes the guide plate 4223, thereby washing away impurities such as lint on the baffle 4222 and the guide plate 4223. This allows the condensation chamber 43 to be cleaned conveniently and effectively without removing the air duct cover 42, greatly improving the user experience.
