Background

With the improvement of living standard of people, personalized household appliances are continuously emerging. Wall-mounted washing apparatuses (such as wall-mounted drum washing machines) have advantages of compact structure, small occupied space, low noise, low cost, and the like, and are therefore favored by more and more users. For example, some wall-mounted washing apparatuses may be used to wash small underwear or infant clothes, etc., not only to wash light weight clothes, but also to prevent cross-infection of bacteria between clothes, and have good economical efficiency and practicability.

In order to provide more functions thereto, a wall-mounted washing apparatus having a drying function has been developed in the related art. For example, chinese patent application CN111809339A discloses a wall-mounted washing machine. The wall-mounted washing machine comprises an outer drum and a drying device, wherein at least part of the drying device is integrally formed on the side wall of the outer drum. The drying device comprises a first air channel and a second air channel, the first air channel is communicated with the air inlet of the outer barrel to convey dry hot air to the inside of the outer barrel, and the second air channel is respectively communicated with the air outlet of the outer barrel and the first air channel to condense wet hot air received from the outer barrel into dry cold air in the second air channel. However, the wall-mounted washing machine has a small overall size and a limited internal space, which results in a small size of the second air duct, and a poor condensation effect of the hot and humid air in the second air duct, resulting in a large humidity of the air entering the first air duct. This not only can reduce the heating efficiency of heater block in the first wind channel, increases the energy consumption, and the ability that the too big dry air of humidity can take away the interior moisture of article of waiting to dry (for example clothing, shoes, cap etc.) descends moreover, has greatly reduced drying efficiency.

The upper part of the condensing channel is provided with a spraying opening used for connecting a spraying device, and the inner wall surface of the condensing channel is provided with a plurality of condensing sheets which can form circulation gaps and are arranged in a staggered manner. The comdenstion water is in the mouth gets into condensing passage through spraying to the condensing piece that lies in the below flows from the condensing piece that lies in the top in the adjacent condensing piece, thereby has increased the length of circulation and the circulation of comdenstion water in condensing passage long, and then increases by the area of contact and the contact time between the comdenstion water that sprays into and the steam that gets into by the interior bucket of washing machine, has promoted drying efficiency. However, the plurality of condensation sheets in the drum of the washing machine are staggered in the condensation channel, so that the wind resistance of the air in the condensation channel is obviously increased, and the air supply efficiency in the condensation channel is greatly reduced. In addition, after entering the condensation channel from the spraying port, the condensed water flows through the plurality of condensation sheets in sequence along the staggered arrangement, the motion track of the condensed water is regular, the contact area of the condensed water and the damp and hot air is limited, and the condensation efficiency is low, so that the washing machine drum has the possibility of improvement.

By configuring the duct cover 42 to be detachably fixed to the duct main body 41, the process requirement of integrally forming the duct main body 41 and the outer tub 10 can be satisfied, and the duct cover 42 can be easily detached by a user to clean, maintain and maintain the condensation chamber 43 from the lateral opening 414. In one or more embodiments, the duct cover 42 is configured to be integrally molded using PP, ABS, or other suitable resin material through an injection molding process to simplify the manufacturing process and facilitate manufacturing. Preferably, a sealing member (not shown) is disposed between the air duct cover 42 and the lateral opening 414, so that the air duct cover 42 can effectively seal the air duct main body 41 and prevent air from flowing out from the installation gap.

As shown in fig. 4, the duct cover 42 has a substantially flat plate-shaped duct cover body 424. The duct cover body 424 has an outer wall 421 and an inner wall 422. In one or more embodiments, a rib 4211 extending in a length direction of the duct cover 42 (i.e., a left-right direction shown in fig. 4) and a height direction of the duct cover 42 (i.e., an up-down direction shown in fig. 4) is formed on the outer wall 421. The arrangement of the reinforcing ribs 4211 can increase the strength and rigidity of the air duct cover 42, so as to prolong the service life of the air duct cover 42.

As shown in fig. 4, in one or more embodiments, a junction tube 423 is formed at an upper portion of the outer wall 421 near a right side of the outer wall 421. Alternatively, the joint pipe 423 may be disposed at an upper portion of the outer wall 421 near the left side of the outer wall 421. Preferably, the joint pipe 423 is integrally formed with the air duct cover main body by an injection molding process by using a suitable resin material, which is beneficial to simplifying a manufacturing process, and can avoid forming holes on the air duct cover main body 424 to prevent air from flowing out from the holes to influence air supply efficiency and noise. As shown in fig. 4, the junction tube 423 is configured in a hollow tubular structure and has a liquid inlet end 4231 and an opposite liquid outlet end 4232. As shown in fig. 1, the inlet end 4231 is configured to be connectable to the first end 441 of the liquid tube 44 to receive the liquid delivered from the liquid tube 44. As shown in fig. 4, a liquid inlet 42311 is formed in the liquid inlet end 4231. The loading port 42311 has a circular cross section, and the loading port 42311 has a diameter d (as shown in FIG. 6). The diameter d ranges from 7mm to 11mm. Preferably, loading port 42311 is 9mm in diameter. Alternatively, loading port 42311 may be configured with other suitable cross-sections, such as oval, semi-circular, and the like. A liquid outlet end 4232 is formed on the outer wall 421 and extends to the inner wall 422 in the direction of the center line C of the joint pipe 423, so that a liquid outlet 4221 is formed on the inner wall 422. As shown in fig. 4 and 5, in one or more embodiments, the joint tube 423 is configured to extend from the inlet end 4231 to the outer wall 421 of the air duct cover 42 in a manner of inclining downwards along a center line C of the joint tube 423, that is, the center line C of the joint tube 423 is at an angle with a plane where the air duct cover 42 is located. Specifically, the vertical projection line of the center line C of the joint pipe 423 on the air duct cover 42 is C ₁ Center line C and vertical projectionLine C ₁ Forming a first predetermined included angle alpha. The first predetermined included angle alpha is in the range of 5 deg. -10 deg.. With the above arrangement, the joint pipe 423 and the duct cover body 424 are held at a predetermined angle therebetween, which facilitates the manufacturing process when the joint pipe 423 and the duct cover body 424 are integrally molded. Further, the joint pipe 423 is disposed to extend from the inlet end 4231 to the air duct cover 42 along the center line C thereof obliquely downward, that is, the center line C of the joint pipe 423 is disposed at an angle with respect to the longitudinal direction D of the air duct cover 42. Specifically, a vertical projection line C of the center line C of the joint pipe 423 on the duct cover 42 ₁ Forming a second predetermined angle β with the length direction D of the duct cover 42. The second predetermined angle beta is in the range of 0 DEG<Beta is less than or equal to 10 degrees. Alternatively, the joint pipe 423 may be configured to extend horizontally from the inlet end 4231 to the duct cover 42 along the center line C thereof. At this time, the second predetermined angle β is 0 °. As can be appreciated, the joint tube 423 is arranged to extend horizontally or obliquely downward from the inlet end 4231 to the air duct cover 42 along its own center line C, such that the joint tube 423 extends substantially along the length direction D of the air duct cover 42, and therefore, when the liquid tube 44 is connected to the joint tube 423, the space at the rear side of the air duct main body 41 can be utilized, which facilitates the pipeline arrangement, and makes the internal structure of the wall-mounted washing apparatus 1 more compact. In addition, the joint pipe 423 is disposed to extend substantially in the longitudinal direction D of the air duct cover 42, and it is also possible to extend the initial flow direction of the liquid introduced into the condensation chamber 43 by the joint pipe 423 substantially in the horizontal direction. Under the action of gravity, the liquid moves approximately in a parabolic manner, so that the liquid has a dispersing tendency in the vertical direction, and further dispersion of the liquid is facilitated.

In one or more embodiments, as shown in fig. 6, a liquid outlet 4221 is formed in an upper portion of inner wall 422. The liquid outlet 4221 is arranged to extend substantially in the direction of the center line C of the joint tube 423 and has a substantially elliptical shape, so that the liquid outlet 4221 has a large opening area. When liquid enters the condensing chamber 43 from the liquid outlet 4221, the liquid is strongly restrained by the liquid outlet 4221, and the guiding effect of the liquid outlet 4221 on the liquid is enhanced.

As shown in fig. 6, in one or more embodiments, baffles 4222 are provided on the inner wall 422. Baffle 4222 is positioned near the liquid outlet4221 are positioned so that liquid flowing from the outlet 4221 into the condensing chamber 43 can easily impinge on the baffle 4222. In one or more embodiments, the baffles 4222 are configured as arcuate plates 42221 that are convex toward the exit orifice 4221. The provision of the arcuate plate 42221 has a greater radial outer surface area than a straight plate for the same transverse length (i.e. the projected length in the lengthwise direction D of the air duct cover 42). Therefore, the liquid has a greater chance of contacting the arcuate plate 42221 under the same windage conditions. Alternatively, the baffles 4222 may be configured in other suitable configurations, such as straight plates, undulating plates, and the like. In one or more embodiments, the centerline C of the joint tube 423 extends through the arcuate plate 42221 such that the arcuate plate 42221 is positioned in a direction that does not deviate from the flow direction of the liquid, thereby increasing the effectiveness of the flow diversion of the arcuate plate 42221. In one or more embodiments, the arcuate plate 42221 is configured to extend perpendicularly outwardly from the inner wall 422 by a first height H ₁ . First height H ₁ The range of (1) is 12mm-15mm, so that the arc-shaped plate 42221 has a moderate height, and the air supply efficiency is prevented from being influenced by the increase of wind resistance caused by overlarge height while the requirement of effective liquid guide is met. The arcuate plate 42221 has a circular arc shaped radial baffle extrados surface 221. The circle center of the radial deflection extrados surface 221 is O ₁ And has a first radius R ₁ And a first radian theta ₁ . Wherein the first radius R ₁ = (3-5) × d, first radian theta ₁ The range of (d) is 0.5rad to 1rad. Through the configuration, the arc-shaped plate 42221 has proper arc length and radian, the air resistance increase caused by too large arc length can be prevented while the flow direction of the liquid is changed due to effective liquid diversion, the air supply efficiency is prevented from being influenced, the effect that the diversion cannot be realized due to the fact that part of the arc-shaped plate 42221 is not in contact with the liquid due to too large radian can also be avoided, and the utilization rate of the whole arc-shaped plate 42221 is reduced. The radial deflection extrados surface 221 intersects the inner wall 422 to form an extrados 2211. The outer arc 2211 has an upper end point 2211a and an opposite lower end point 2211b in the vertical direction. As shown in FIG. 7, the tangent line E of the outer arc 2211 passing through the upper end point 2211a and the vertical projection line C of the central line C of the joint pipe 423 on the air duct cover 42 ₁ Forming a third predetermined angle gamma. The third predetermined included angle gamma is in the range of 15 deg. -25 deg.,so that the arc plate 42221 is relatively fixed in position in the circumferential direction thereof to obtain a good flow guiding effect.

As shown in fig. 6, in one or more embodiments, 3 baffles 4223 are disposed spaced apart from each other below exit orifice 4221. The guide plate 4223 can break up part of liquid guided by the guide plate 4222, so that the contact probability and the contact area of the hot and humid air and the liquid are greatly increased, and the condensation efficiency of the condensation assembly 40 is improved. Alternatively, the number of the baffles 4223 may be configured to be other suitable numbers more or less than 3. Each baffle 4223 is configured to extend vertically outwardly from the inner wall 422 by a second predetermined height H ₂ . Second predetermined height H ₂ The range of the air guide plates is 8mm-10mm, so that each air guide plate 4223 has a proper height, the air guide plate 4223 with too small height can be prevented from not scattering liquid, and the air supply efficiency is prevented from being influenced by increased wind resistance caused by too large height. A diversion port 4224 is formed between the adjacent diversion plates 4223, and is a first diversion port 224a and a second diversion port 224b in sequence. Due to the arrangement of the flow guide openings 4224, part of liquid guided by the baffle plates 4222 can flow out of the flow guide openings 4224, the dispersion degree of the liquid is increased, the liquid is more uniformly distributed in the condensation chamber 43, and the condensation efficiency is further improved. The width range of each flow guide opening 4224 is 3mm-5mm, so that the flow guide openings 4224 have proper width, the probability that liquid flows out of the flow guide openings 4224 due to too small width can be prevented, and the effect of scattering the liquid due to the fact that most of the liquid directly flows through the flow guide openings 4224 without being blocked by the flow guide plate 4223 due to too large width can be prevented. Preferably, each of the orifices 4224 is provided with the same width. Alternatively, each of the diversion ports 4224 may be configured with different widths, for example, the width of the first diversion port 224a is 3mm, and the width of the second diversion port 224b is 5mm, so as to obtain a richer product for meeting the actual needs. As shown in fig. 7, in one or more embodiments, each baffle 4223 is arranged as an arcuate baffle 42231, in turn a first arcuate baffle 231a, a second arcuate baffle 231b and a third arcuate baffle 231c, and all arcuate baffles 42231 together form a radially flow directing outer arc 4225 that is convex away from the exit orifice 4221. Arc guide plate42231 is arranged so that the baffle 4223 has a larger radial outer surface area, the chance of liquid contact with the baffle 4223 increases, and the effect of the baffle 4223 in dispersing liquid increases. As shown in FIG. 7, the center of the radial flow guiding extrados 4225 is O ₂ And has a second radius R ₂ And a second arc θ ₂ . Wherein the second radius R ₂ = (1-1.6) × d, second radian θ ₂ In the range of 2.4rad to 3.14rad. With the above configuration, the curved baffle 42231 has a moderate arc length and arc. When satisfying effectively break up liquid, can prevent that arc length and radian are too big to lead to the windage too big, influence air supply efficiency, also can avoid simultaneously that partial guide plate 4223 does not play the effect of breaking up liquid with liquid contact, reduces guide plate 4223's utilization ratio.

As shown in fig. 1, in one or more embodiments, the liquid tube 44 is configured as a hollow hose to facilitate tubing arrangement. The liquid tube 44 may be made of PVC, PU or other suitable material. The liquid tube 44 has opposite first and second ends 441, 442. The first end 441 is disposed to be connected to the inlet end 4231 of the junction pipe 423, and the second end 442 is configured to communicate with an output end of a solenoid valve (not shown). The solenoid valve is electrically connected to the control system of the wall-mounted washing apparatus 1 so as to adjust the flow rate of the liquid in the liquid pipe 44 by controlling the opening degree of the solenoid valve, thereby meeting the requirements under different working conditions. The solenoid valves include, but are not limited to, direct-acting solenoid valves, step-by-step direct-acting solenoid valves, pilot operated solenoid valves, and the like. In one or more embodiments, an input end (not shown) of the solenoid valve communicates with a condensate-collecting box (not shown) in the wall-mounted washing apparatus 1 to deliver condensate into the condensing chamber 43 through the liquid pipe 44. Alternatively, the input of the solenoid valve may be connected to other suitable fluid lines, such as a mains water inlet line.

In one or more embodiments, the wall-mounted washing appliance 1 further comprises a filter assembly (not shown). The filter assembly may be disposed at a suitable location within the condensing chamber 43, such as near an upper portion of the bottom inlet 416, to facilitate filtering of hot and humid air flowing in from the bottom inlet 416 to prevent lint and other contaminants from clogging the condensing chamber 43 or affecting the cleanliness within the condensing chamber 43. The filter assembly may also be disposed at a suitable position in the supply air duct 30, for example, a position near the supply end 31, so as to filter the dry and hot air flowing from the exhaust port of the fan, and prevent impurities such as lint from blocking the supply air duct 30 or flowing into the outer tub 10. The filter assembly has a filter (not shown) which may be a metal rubber filter, a nylon filter, or other suitable filter. In addition, the filtering assembly may be disposed in both the condensing chamber 43 and the air supply duct 30 to enhance the filtering effect.

When the wall-mounted washing device 1 of the present invention is in a drying condition, a user may select different preset drying programs through the control system. Alternatively, various parameters of the drying process, such as drying temperature, drying time, etc., may also be set manually to meet personalized requirements of users. When the drying function is turned on, the impeller 22 is rotated by the motor to suck the air in the condensing chamber 43 into the scroll 21. The air is heated to dry hot dry air while passing over the surface of the heating member 23. The dry air is guided by the air supply duct 30 and is supplied into the tub 10 through the tub inlet 1311. The drying air exchanges heat with the articles to be dried in the inner cylinder, takes away the moisture in the articles to be dried and converts the moisture into damp and hot air, and the purpose of drying the articles to be dried is achieved. The hot and humid air is discharged out of the cylindrical body 12 through the outer cylindrical outlet 1211 provided on the side wall 121 and enters the condensing chamber 43 again. At this time, the solenoid valve is in the energized state and has a small opening degree, and the flow rate of the liquid (e.g., condensed water) in the liquid pipe 44 is slow. The liquid is sent into the condensation chamber 43 through the joint pipe 423. After flowing out from the liquid outlet 4221, the liquid impacts on a baffle 4222 close to the liquid outlet 4221, and the flow direction of the liquid is changed and is guided to a baffle 4223. Part of the liquid is broken up by impacting on the guide plates 4223, and part of the liquid passes through the guide openings 4224 between the guide plates 4223 which are arranged at intervals, so that the liquid in the condensation chamber 43 is uniformly dispersed. The hot and humid air is in sufficient contact with the liquid to convert the hot and humid air into cold dry air and condensed water. The dry and cool air is again drawn into the scroll casing 21 by the impeller 22, and the air circulation in the wall-mounted washing apparatus 1 is achieved. In addition, under the action of its own gravity, the condensed water and the liquid enter the cylindrical body 12 from the bottom opening 416 (i.e., the outer cylinder air outlet 1221) at the bottom of the air duct main body 41, flow to the liquid discharge port (not shown in the figure) along the bottom wall of the cylindrical body 12, and are collected in the condensed water collection box, so as to realize the recycling of the condensed water.

When the wall-mounted washing apparatus 1 of the present invention is in a cleaning condition, the solenoid valve is in a power-on state and has a large opening degree, and the flow rate of the liquid in the liquid pipe 44 is fast. The liquid is supplied into the condensing chamber 43 through the joint pipe 423 and has a large impact force. Liquid strikes on baffling board 4222 for its flow direction changes and dashes to guide plate 4223, and partial liquid strikes on guide plate 4223, so that wash impurity such as thread scraps on baffling board 4222 and the guide plate 4223 away, make also can carry out convenience, clean effectively to condensation chamber 43 under the condition of not dismantling wind channel cover 42, promoted user experience greatly.
