[0041] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] Example 1

[0043] The existing integrated washer-dryer uses a condenser for cooling, and the condensation structure is complex and the cost is high, which makes the integrated machine thick and heavy. In the prior art, the patent with application number CN201811532830.3 discloses a drum-type integrated washer-dryer, including a water tub, and the rear side wall of the water tub is provided with an inner cylinder shaft hole; the inner side of the rear side wall of the water tub is fixedly connected with a condensation plate, and a closed chamber is formed between the rear side wall of the water tub and the condensation plate; the outer side of the rear side wall of the water tub is fixedly connected with a cooling water inlet and a cooling water outlet connected to the closed chamber. Although this patent cancels the condenser and uses a condensation plate for condensation, the cost is reduced; the thickness of the whole machine is reduced; however, the condensation plate is a plate-like structure, the contact area between the condensed water and the surface of the condensation plate is limited, and the condensation effect is poor; on the other hand, the air path and the water path are not isolated, and there will be a problem of cooling water wetting clothes twice.

[0044] like Figures 1 to 7 As shown, in order to solve the above problems, this embodiment proposes a wall-mounted washer-dryer 100, as shown in FIG. Figure 3 As shown, the wall-mounted washer-dryer 100 includes:

[0045] A barrel assembly 130, wherein the barrel assembly 130 comprises an outer barrel 131 and an inner barrel 132 connected together;

[0046] A condensation structure 140, wherein the condensation structure 140 is a condensation pan 141, and the condensation pan 141 is installed on the inner side of the bottom of the outer tube 131, a condensation chamber is formed between the condensation pan 141 and the bottom of the outer tube 131, and a return air channel is formed between the condensation pan 141 and the bottom of the inner tube 132;

[0047] like Figure 5 As shown, the condensation plate 141 includes a plate body 1411, and a first mounting edge 1412 is provided on the outer circumference of the plate body 1411. Figure 6 and Figure 7 As shown, a connecting plate 1417 is provided between the disk body 1411 and the first mounting edge 1412 , the disk body 1411 and the first mounting edge 1412 are provided in parallel, and an angle α between the connecting plate 1417 and the first mounting edge 1412 is satisfied: 25°≤α≤35°.

[0048] In the wall-mounted washer-dryer 100 described in this embodiment, on the one hand, the disc body 1411 is arranged parallel to the first mounting edge 1412, and the angle between the connecting plate 1417 and the first mounting edge 1412 is α, and α satisfies: 25°≤α≤35°. In a limited space, the contact area between the condensed water and the surface of the condensed water disc 141 is effectively increased while ensuring the strength of the condensed water disc 141, thereby increasing the condensation effect. On the other hand, the condensed water disc 141 is installed on the inner side of the bottom of the outer cylinder 131, so that the air path and the water path of the wall-mounted washer-dryer 100 are separated, which can prevent the cooling water from wetting the clothes for the second time; at the same time, the structural strength of the outer cylinder 131 is also enhanced.

[0049] More specifically, in this embodiment, the angle between the connecting plate 1417 and the first mounting edge 1412 is α, and α=30°.

[0050] This arrangement effectively increases the contact area between the condensed water and the surface of the condensation pan 141 within a limited space while ensuring the strength of the condensation pan 141, thereby increasing the condensation effect.

[0051] More specifically, Figure 5 As shown, a first mounting hole is provided on the first mounting edge 1412 .

[0052] Specifically, Figure 5 and Figure 6 As shown, reinforcing ribs 1415 are provided on the condensation tray 141 , and the reinforcing ribs 1415 are distributed in a ring shape on the condensation tray 141 .

[0053] This arrangement firstly increases the structural strength of the condensation tray 141; secondly, effectively increases the contact area between the condensed water and the surface of the condensation tray 141 within a limited space, thereby increasing the condensation effect; and thirdly, serves to guide the condensed water on the condensation tray 141.

[0054] Specifically, Figure 5 As shown, an air inlet notch 1416 is provided on the condensation plate 141 , and the air inlet notch 1416 cooperates with the return air channel to let air into the drying structure 150 .

[0055] Specifically, Figure 5 As shown, the cylinder assembly 130 further includes a driving structure 133, and the driving structure 133 includes an output shaft 1331. A first through hole 1413 is provided at the center of the condensation plate 141. Figure 3 As shown, the first through hole 1413 matches with the output shaft 1331 of the driving structure 133 .

[0056] The first through hole 1413 allows the output shaft 1331 of the driving structure 133 to pass through, so that the output shaft 1331 of the driving structure 133 can be connected to the inner cylinder 132 and drive the inner cylinder 132 to rotate relative to the outer cylinder 131 .

[0057] Specifically, Figure 5 As shown, a second mounting edge 1414 is provided on the outer circumference of the first through hole 1413 , and the condensation plate 141 is mounted on the driving structure 133 via the second mounting edge 1414 .

[0058] More specifically, Figure 5 As shown, a second mounting hole is provided on the second mounting edge 1414 .

[0059] Specifically, the condensation plate 141 is integrally formed.

[0060] This configuration enables the condensation pan 141 to have better structural strength.

[0061] Specifically, the condensation plate 141 is made of metal aluminum.

[0062] The metal aluminum material makes the condensation plate 141 have good thermal conductivity, which facilitates the condensation plate 141 to better exchange heat with condensed water.

[0063] Taking advantage of the characteristics of the metal aluminum material of the condensation plate 141, its thermal conductivity coefficient is higher than that of other materials, and the heat exchange efficiency is high. The hot and humid air is first cooled by passing through the metal aluminum condensation plate 141, which can achieve a good dehumidification effect, thereby improving the heat exchange efficiency with the air, thereby improving the condensation efficiency of the washer-dryer and shortening the drying time.

[0064] Specifically, a condensation water inlet pipe and a first drainage pipe are provided on the outer tube 131 , and the condensation water inlet pipe and the first drainage pipe are communicated with the condensation chamber.

[0065] The cooling water enters from the condensation water inlet pipe and is discharged from the first drain pipe, thereby cooling the condensation tray 141 .

[0066] Specifically, Figure 3 As shown, the wall-mounted washer-dryer 100 also includes a drainage structure 160, and the drainage structure 160 is arranged below the barrel assembly 130. The drainage structure 160 includes a drainage pump 161 and a main drainage pipe 162. The first drainage pipe is connected to the drainage pump 161, and the drainage pump 161 is connected to the main drainage pipe 162. After the condensed water is discharged from the first drainage pipe, it is transported to the main drainage pipe 162 by the drainage pump 161, and then discharged to the outside of the wall-mounted washer-dryer 100.

[0067] Specifically, Figure 3As shown, the wall-mounted washer-dryer 100 also includes a drying structure 150, which is arranged above the barrel assembly 130. The drying structure 150 includes a drying air duct 151. A return air port 1321 is arranged above the bottom of the inner barrel 132, and an air inlet 1322 is arranged above the side opposite to the return air port 1321. One end of the drying air duct 151 is connected to the return air port 1321, and the other end of the drying air duct 151 is connected to the air inlet 1322.

[0068] Specifically, Figure 3 As shown, a PTC heating device 153 is installed in the drying duct 151, and the duct of the drying duct 151 connected to the air inlet 1322 on one side of the PTC heating device 153 is an outlet duct 154, and the outlet duct 154 is arranged in an arc shape on one side close to the casing 110 of the wall-mounted washer-dryer 100.

[0069] This arrangement facilitates the coordination between the air outlet duct 154 and the outer shell 110, so that the overall structure of the wall-mounted washer-dryer 100 after the outer shell 110 is covered is relatively round and smooth, with fewer protrusions or sudden changes in cross-section. The arc shape can reduce the corners and sharp edges of the structure, alleviate stress concentration in the structure, and improve the strength and stability of the overall structure, thereby improving the structural integrity of the wall-mounted washer-dryer 100, increasing its beauty and aesthetic value, and improving its overall quality, allowing it to better integrate into the home environment.

[0070] Specifically, a circulating fan 152 is installed on one side of the drying air duct 151 near the return air port 1321. Figure 3 As shown, a PTC heating device 153 is installed on the other side of the circulating fan 152 .

[0071] Specifically, Figure 1 and Figure 2 As shown, the housing 110 includes a front housing 101 and a rear housing 102, and the front housing 101 is detachably connected to the rear housing 102. A screw connection platform is provided on the rear housing 102, and correspondingly, a screw connection platform is provided on the front housing 101, and the screw connection platform on the rear housing 102 is connected to the screw connection platform on the front housing 101 by connecting screws, and the connecting screws are threaded from back to front. This setting further ensures the integrity of the appearance of the wall-mounted washer-dryer 100, avoids users from seeing too many appearance joints and connecting screws when using it, ensures the stable connection of the housing 110, and improves the user experience.

[0072] Specifically, Figure 3As shown, a front sealing door 120 is provided at the front end of the cylinder assembly 130 , and the front sealing door 120 is used to cover the cylinder assembly 130 and fix structures such as door locks and hinges.

[0073] Specifically, Figure 3 As shown, the front sealed door 120 includes a door body 121 and a door glass 122. The door glass 122 is arranged on the door body 121. An arc-shaped groove 123 is arranged above the door glass 122. The arc-shaped groove 123 cooperates with the air inlet 1322 to introduce air into the barrel assembly 130. The setting of the arc-shaped groove 123 can prevent the drying hot air from running to both sides, so that all the drying hot air can enter the inner barrel 132 to dry the clothes.

[0074] In the wall-mounted washer-dryer 100 described in the present embodiment, a circulating fan 152 is installed on one side of the drying air duct 151 close to the return air outlet 1321 to facilitate the entry of condensed air into the drying air duct 151, and a PTC heating device 153 is installed on the other side of the circulating fan 152 to heat the air in the drying air duct 151 to generate dry hot air, which enters the inner drum 132. The dry hot air heats the wet clothes, and the moisture in the wet clothes evaporates to generate hot and humid air. The hot and humid air contacts the condensation plate 141 and exchanges heat, so that the moisture in the air is condensed. The air is then sucked back into the drying air duct 151 from the return air outlet 1321 by the circulating fan 152 through the flushing component 170, forming a circulation of the air path.

[0075] The wall-mounted washer-dryer 100 described in this embodiment supplies cold water to the condensation chamber between the condensation plate 141 and the bottom of the outer cylinder 131 through the condensation water inlet pipe, so that the temperature of the condensation plate 141 is relatively low, and the hot and humid air in the return air channel contacts the condensation plate 141 and condenses to form condensed water after heat exchange. The condensed water and the cold water in the condensation chamber flow downward due to gravity and are discharged through the drainage pump 161 and the main drainage pipe 162 at the bottom of the cylinder assembly 130.

[0076] The wall-mounted washer-dryer 100 described in this embodiment has the following beneficial effects:

[0077] 1. The condenser is eliminated, and the condensation structure 140 is a condensation plate 141. The condensation plate 141 has a simple structure. On the one hand, it reduces the cost of the wall-mounted washer-dryer 100; on the other hand, it reduces the thickness of the entire wall-mounted washer-dryer 100.

[0078] 2. The disk body 1411 is arranged parallel to the first mounting edge 1412, and the angle between the connecting plate 1417 and the first mounting edge 1412 is α, and α satisfies: 25°≤α≤35°. In a limited space, the contact area between the condensed water and the surface of the condensed disk 141 is effectively increased while ensuring the strength of the condensed disk 141, thereby increasing the condensation effect.

[0079] 3. The condensation plate 141 is installed on the inner side of the bottom of the outer drum 131, so that the air path and the water path of the wall-mounted washer-dryer 100 are separated, which can prevent the cooling water from wetting the clothes for the second time.

[0080] Example 2

[0081] In this embodiment, different from the embodiment 1, Figure 8 , Fig. 9 and Fig.10 As shown, a sealing structure 142 is provided between the condensation pan 141 and the bottom of the outer tube 131 , and a closed condensation chamber is formed between the condensation pan 141 and the bottom of the outer tube 131 .

[0082] The condensation tray 141 is installed on the inner side of the bottom of the outer drum 131, and a sealing structure 142 is provided between the condensation tray 141 and the bottom of the outer drum 131 to isolate the air path and water path of the wall-mounted washer-dryer 100, thereby preventing the cooling water from wetting the clothes for the second time.

[0083] Specifically, Fig.10 As shown, the sealing structure 142 is configured as a first sealing ring 1421 .

[0084] Specifically, a mounting groove 1418 is provided on the condensation plate 141 , one end of the sealing structure 142 is installed in the mounting groove 1418 , and the other end of the sealing structure 142 is arranged to fit the bottom of the outer cylinder 131 .

[0085] Specifically, the opening diameter of the condensation water inlet pipe is d 1 , the opening diameter of the first drain pipe is d 2 , d 1 >d 2 .

[0086] This arrangement allows the cooling water in the closed condensation chamber to flow in quickly and drain out slowly, so that the cooling water can be retained in the closed condensation chamber for a longer period of time, thereby improving the utilization rate of the cooling water and the condensation effect on the condensation plate 141.

[0087] More specifically, in this embodiment, the opening diameter of the condensation water inlet pipe is d 1 , the opening diameter of the first drain pipe is d 2 , d 1 =2d 2.

[0088] This arrangement allows the cooling water in the closed condensation chamber to flow in quickly and drain out slowly, so that the cooling water can be retained in the closed condensation chamber for a longer period of time, thereby improving the utilization rate of the cooling water and the condensation effect on the condensation plate 141.

[0089] Specifically, Figure 5 and Figure 8 As shown, a first groove 1422 is formed on the first sealing ring 1421 , and the first groove 1422 cooperates with the air inlet notch 1416 to allow air to enter the drying structure 150 .

[0090] Example 3

[0091] The patent application number CN202211086044.1 in the prior art discloses a self-cleaning structure of a filter screen for a clothes drying device and a clothes drying device, including a cleaning device installed on the outer wall of the drying air duct, the cleaning device is connected to the inside of the drying air duct, and the connecting area is located above the filter screen assembly in the drying air duct, a water injection port is provided on the cleaning device, and a drain port is provided on the drying air duct, and the water entering the cleaning device from the water injection port flows into the drying air duct, passes through the filter screen on the filter screen assembly, and then flows out from the drain port. Although the patent arranges a cleaning device fixedly connected to the drying air duct above the filter screen assembly, by injecting clean water into the cleaning device, the filter screen is flushed by the impact force of the water flowing downward, so that the hair debris accumulated on the filter screen is flushed away, and then the sewage and the hair debris are discharged from the drain port, the cleaning operation of the filter screen can be realized, and there is no need to manually remove the filter screen from the drying air duct for cleaning regularly, which saves time and effort. However, the water flow of the cleaning device does not have enough guiding media to cover the entire filter surface, so the hair stuck on the filter cannot be washed away in time, which ultimately causes the clothes to fail to dry; in addition, the cleaning device is installed on the outer wall of the drying duct and the cleaning device is large in size, which makes the all-in-one machine thick and heavy, which is not conducive to wall-mounting the washer-dryer; and is not conducive to forming a more rounded and beautiful structure of the washer-dryer.

[0092] In this embodiment, in order to solve the above problems, Figures 11 to 15 As shown, the wall-mounted washer-dryer 100 described in this embodiment includes a flushing assembly 170, and the flushing assembly 170 is installed inside the drying air duct 151, such as Fig.11 , Fig.13 and Fig.15As shown, a filter screen 173 is installed on the flushing component 170, and a flushing water chamber 175 is set on the flushing component 170.
