DETAILED DESCRIPTION

[0050] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0051] When existing clothing processing equipment uses condensation to dry clothes, the heat exchange between cooling water and hot, humid air is insufficient. In the embodiments of the present invention, an external condensation chamber is provided outside the bottom wall of the outer drum, and ribs are arranged in opposite and staggered patterns within the chamber. When the cooling water enters the chamber, it oscillates within the chamber, increasing the contact area between the cooling water and the hot, humid air. The hot, humid air passes through different ribbed surfaces as it passes through the chamber, extending its stay in the condensation duct. This improves condensation efficiency and conserves cooling water.

[0052] The following is combined with Figure 1 -Attached Figure 4 The technical solution of this embodiment is described in detail. In the absence of embossing, the following implementation methods and embodiments can be combined with each other.

[0053] Example

[0054] like Figure 1-Figure 4 As shown, the first aspect of this embodiment proposes a condensing structure for a drying system of a clothes processing device, the condensing structure comprising an outer drum bottom wall and an air duct cover 7;

[0055] The outer wall surface 12 of the outer cylinder bottom wall forms a first condensation surface, and the air duct cover 7 is arranged on the first condensation surface and forms an outer condensation chamber 4 with the first condensation surface; the inner wall surface of the air duct cover 7 opposite to the first condensation surface forms a second condensation surface;

[0056] The first condensation surface is formed with m first ribs 61 convex toward the second condensation surface and extending obliquely downward, and the second condensation surface is formed with n second ribs 62 convex toward the first condensation surface and extending obliquely downward, where m≥2 and n≥2;

[0057] The distance between the first condensation surface and the second condensation surface at the location of the i-th first rib 61 is wi, and the distance between the first condensation surface and the second condensation surface at the location of the j-th second rib 62 is wj;

[0058] The first rib 61 includes a first connection end 611 connected to the first condensation surface and a first free end 612 extending obliquely downward from the first connection end 611. The second rib 62 includes a second connection end 621 connected to the second condensation surface and a second free end 622 extending obliquely downward from the second connection end 621. The distance from the first free end of the i-th first rib 61 to the first condensation surface is pi, where pi is less than wi. The distance from the second free end of the j-th second rib 62 to the second condensation surface is pj, where pj is less than wj.

[0059] From top to bottom along the condensation chamber, the first ribs 61 and the second ribs 62 are alternately arranged, and for every two adjacent ribs, the projection of the free end of the upper rib on the plane where the upper surface of the lower rib is located falls on the upper surface of the lower rib.

[0060] like Figure 1 As shown, in the embodiment of the present invention, an outer condensation chamber 4 is provided on the outer wall surface 12 of the bottom wall of the outer cylinder 1, and first and second convex ribs 61 and 62 are provided in the outer condensation chamber 4 in a relative and staggered manner. When the condensed water enters the outer condensation chamber 4, the cooling water can oscillate between the first condensation surface and the second condensation surface, thereby increasing the contact area between the cooling water and the humid hot air in the outer condensation chamber 4. When the humid hot air passes through the outer condensation chamber 4, it passes through different ribs {first convex rib 61 and second convex rib 62} wall surfaces, and therefore stays in the outer condensation chamber 4 for a longer time, thereby improving the condensation efficiency and saving cooling water.

[0061] Specifically, when the humid hot air enters the outer condensation chamber 4 through the first air inlet 13, it flows from bottom to top, and the cooling water flowing out of the water inlet device flows from top to bottom. The upward flowing humid hot air flow exchanges heat with the cooling water flowing from top to bottom, and the cooling water condenses the humid hot air. To be more specific, when the cooling water flowing out of the water inlet device falls on the first rib 61 on the outer wall surface 12, it can flow along the first rib 61 and flow to the second rib 62 located below the current first rib 61 and provided on the inner air duct surface. The cooling water flowing onto the second rib 62 can also flow along the second rib 62 and flow to the first rib 61 located below the current second rib 62 and provided on the outer wall surface 12. That is, the cooling water flowing out of the water inlet device can pass through different rib wall surfaces {first rib 61 and second rib 62} when flowing from top to bottom, thereby realizing oscillation between the first condensation surface and the second condensation surface, so that the cooling water stays in the outer condensation chamber 4 for a longer time, thereby improving the condensation efficiency and saving cooling water.

[0062] It should be noted that the hot and humid air will not completely enter the outer condensation chamber 4. Most of the hot and humid air will exchange heat in the inner condensation chamber 3. Cooling water also flows in the inner condensation chamber 3. The cooling water in the inner condensation chamber 3 can exchange heat with the hot and humid airflow in the inner condensation chamber 3. The dry gas after heat exchange can be discharged through the air outlet 14.

[0063] It should also be noted that the reason why the first rib 61 is set on the outer wall surface 12 of the outer cylinder 1 in the embodiment of the present invention is, on the one hand, to facilitate the setting of the first rib 61, and the first rib 61 can be injection molded as one piece with the outer cylinder; on the other hand, since the first rib 61 is directly set on the outer wall surface 12, the coldness of the cooling water flowing in the inner condensation chamber 3 can also be indirectly transferred to the first rib 61, thereby further improving the condensation effect of the first rib 61 on the hot and humid airflow in the external condensation chamber 4.

[0064] It should also be noted that the cooling water mentioned above can be condensed water after condensation, cooling water after cooling by a refrigeration device, or tap water directly from a tap water pipe. The embodiment of the present invention does not specifically limit the temperature and source of the cooling water.

[0065] It should also be noted that the transverse or longitudinal cross-section of the first convex rib 61 and the second convex rib 62 can be straight or arc-shaped. The shape of the guide rib is not specifically limited in the embodiment of the present invention.

[0066] It should also be noted that, compared with the traditional method of increasing the condensation area to improve the condensation efficiency by adding metal condensation plates, the clothing processing device in the embodiment of the present invention can improve the condensation efficiency without increasing the cost of parts by adding a rib structure to the outer wall surface 12 of the outer drum 1 and the surface of the air duct cover 7.

[0067] In any of the above embodiments, the distance between the first condensation surface and the second condensation surface is w, the distance that the first rib 61 protrudes toward the second condensation surface is p1, p1 is less than w and greater than w / 2, and the distance that the second rib 62 protrudes toward the first condensation surface is p2, p1 is less than w and greater than w / 2.

[0068] To further enhance the splashing effect of cooling water in the outer condensation chamber 4, in the embodiment of the present invention, pi is set to be greater than wi / 2, and pj is set to be greater than wj / 2. Furthermore, for each pair of adjacent ribs, the extended surface of the upper rib is configured to intersect with the upper surface of the lower rib, thereby enhancing the condensation effect in the outer condensation chamber 4.

[0069] In order to further increase the flow time of cooling water in the outer condensation chamber 4, as shown in FIG. Figure 1 As shown, relative to the first connecting end 611 and the first free end 612 , the position where the downward projection of the second free end 622 coincides with the first rib 61 is close to the first connecting end 611 ;

[0070] With respect to the second connecting end 621 and the second free end 622 , the position where the downward projection of the first free end 612 overlaps with the second rib 62 is close to the second connecting end 621 .

[0071] In the embodiment of the present invention, the downward projection of the second free end 622 and the overlapping position of the first rib 61 are set to be close to the first connecting end 611, so that the cooling water falling onto the first rib 61 can increase the flow time of the cooling water on the first rib 61 when flowing along the first rib 61.

[0072] In the embodiment of the present invention, the downward projection of the first free end 612 and the overlapping position of the second rib 62 are set to be close to the second connecting end 621, so that the cooling water falling onto the second rib 62 can increase the flow time of the cooling water on the second rib 62 when flowing along the second rib 62.

[0073] In any of the above embodiments, Figure 2 and Figure 3 As shown, the first rib 61 has a first upper surface 613 and a first lower surface 614 opposite to each other;

[0074] The second rib 62 has a second upper surface 623 and a second lower surface 624 opposite to each other;

[0075] A first convex-concave structure 615 is formed on the first upper surface 613 , and a second convex-concave structure 625 is formed on the second upper surface 623 .

[0076] In the embodiment of the present invention, a convex and concave structure {615, 625} is provided on the first convex rib 61 and the second convex rib 62, so that when cooling water flows into the first convex rib 61 and the second convex rib 62, a water film can be formed on the first convex rib 61 and the second convex rib 62. In this way, when the hot and humid air flow flows in the external condensation chamber 4, the hair debris entrained in the hot and humid air flow can adhere to the water film, thereby preventing the hair debris from being sucked into the drying fan along with the air flow.

[0077] Specifically, such as Figure 2 and Figure 3 As shown, the first convex-concave structure 615 and the second convex-concave structure 615 are both wave-shaped convex-concave structures;

[0078] The first convex-concave structure 615 includes one or more first ridges extending transversely on the first upper surface 613 and one or more first valleys extending transversely on the first upper surface 613 along the protruding direction of the first rib 61;

[0079] The second convex-concave structure 625 includes one or more second ridges extending transversely on the second upper surface 623 and one or more second valleys extending transversely on the second upper surface 623 along the protruding direction of the second rib 62 .

[0080] Furthermore, the first ridge and the second ridge are both provided in plurality;

[0081] A first concave valley is formed between two adjacent first ridges, and a second concave valley is formed between two adjacent second ridges.

[0082] In the embodiment of the present invention, a first valley is formed between two adjacent first ridges, and a second valley is formed between two adjacent second ridges. In this way, multiple valleys can be set on the first rib 61 and the second rib 62. This can extend the flow time of cooling water on the guide ribs and form multiple water films on the guide ribs, thereby further improving the flow time of cooling water in the external condensation chamber 4 on the one hand, and further improving the collection effect of hair debris in the hot air flow on the other hand.

[0083] In any of the above embodiments, the first convex rib 61 is integrally formed on the outer wall surface of the bottom wall of the outer cylinder, and the second convex rib 62 is integrally formed on the inner wall surface of the air duct cover.

[0084] A second aspect of an embodiment of the present invention further provides a clothes processing device, which includes the above-mentioned condensation structure, wherein the clothes processing device includes:

[0085] The outer cylinder 1, the bottom wall of the outer cylinder 1 is also formed on the inner wall surface 11 opposite to the outer wall surface 12 of the outer cylinder 1;

[0086] The inner cylinder 2 is rotatably disposed in the outer cylinder 1, and an inner condensation chamber 3 is formed between the bottom wall of the inner cylinder 2 and the inner wall surface 11 of the outer cylinder 1;

[0087] The bottom wall of the outer cylinder 1 is further provided with a first air inlet 13 penetrating the inner wall surface 11 and the outer wall surface 12. The first air inlet 13 is provided at the bottom of the outer condensation chamber 3. The top of the outer condensation chamber 4 is provided with an air outlet 14. The air outlet 14 is used to discharge the dry air in the outer condensation chamber 4 and the inner condensation chamber 3.

[0088] The water inlet device has a first water outlet end 5 and a second water outlet end. The first water outlet end 5 of the water inlet device is provided at the top of the outer condensing chamber 4 and communicates with the outer condensing chamber 4, and is used to flow cooling water into the outer condensing chamber 4. The second water outlet end of the water inlet device is provided at the top of the inner condensing chamber 3 and communicates with the inner condensing chamber 3, and is used to flow cooling water into the inner condensing chamber 4.

[0089] The outer condensation chamber has a condensation structure according to any one of claims 1 to 7;

[0090] The condensed water flowing into the outer condensation chamber through the first water outlet 5 is splashed down step by step through the staggered first convex ribs 61 and the second convex ribs 61 .

[0091] Specifically, the position of the first rib closest to the first water outlet is higher than the position of the second rib closest to the first water outlet; the water from the first water outlet is first sprayed onto the upper surface of the first rib 61, and then splashes step by step onto the staggered second rib 61 and first rib 61.

[0092] Of course, in any of the above embodiments, the clothes processing device further includes a second flow guiding structure {not shown in the figure};

[0093] The second guide structure includes a plurality of inner guide ribs arranged in the inner condensation chamber 3 , which are distributed in the height direction of the inner condensation chamber 3 , and one end of the inner guide rib is connected to the inner wall surface 11 and the other end protrudes toward the inner condensation chamber 3 .

[0094] When the clothes processing device dries the clothes in the inner drum 2, part of the hot and humid air flow is condensed in the inner condensation chamber 3, and the other part of the hot and humid air flow enters the outer condensation chamber 4 through the first air inlet 13 for condensation, thereby achieving a double condensation effect.

[0095] Furthermore, the inner guide ribs in the inner condensing chamber 3 and the first convex ribs 61 in the outer condensing chamber 4 are arranged alternately relative to the bottom wall of the outer cylinder 1 .

[0096] The reason why the inner guide ribs and the first convex ribs 61 are staggered relative to the bottom wall of the outer tube 1 in the embodiment of the present invention is to avoid the inner and outer ribs from overlapping in the axial direction of the outer tube 1, avoid the generation of thermal resistance, and improve the condensation heat exchange effect of the two condensation surfaces of the rear wall of the outer tube 1.

[0097] In any of the above embodiments, Figure 1 As shown, the bottom wall of the outer tube 1 is further provided with a second air inlet 15 penetrating the inner wall surface 11 and the outer wall surface 12. The second air inlet 15 is provided above the first air inlet 13, and the first convex rib 61 and the second convex rib 62 are provided between the first air inlet 13 and the second air inlet 15.

[0098] The air flow area of ​​the first air inlet 13 is larger than the air flow area of ​​the second air inlet 15 .

[0099] In the embodiment of the present invention, by setting the air flow area of ​​the first air inlet 13 to be larger than the air flow area of ​​the second air inlet 15, the flow path of the humid and hot air flow in the condensation air duct {inner condensation chamber and outer condensation chamber} can be extended, that is, a large amount of humid and hot air flow is avoided from being discharged directly through the second air inlet 15 without condensation, thereby further improving the condensation effect of the humid and hot air flow.

[0100] In any of the above embodiments, Figure 1 As shown, the clothes processing device further includes a heating air duct 8, the heating air duct 8 has an air inlet end, and the air inlet end of the heating air duct 8 is connected to the air outlet end of the air outlet 14;

[0101] The heating air duct 8 also has an air outlet end, and the air outlet end of the heating air duct 8 is connected to the inner cylinder 2;

[0102] The heating air duct 8 is provided with a drying fan 81 and a heating device 82, wherein the drying fan 81 is arranged closer to the air inlet end of the heating air duct 8 relative to the heating device 82, and the heating device 82 is arranged on the air outlet side of the drying fan 81, for heating the drying air flow sucked into the heating air duct 8;

[0103] Under the action of the drying fan 81 , the air flow entering the outer condensation chamber 4 is sucked into the heating air duct 8 through the air outlet 14 , and returns to the inner drum 2 after being heated.

[0104] In any of the above embodiments, the water inlet device includes a tee pipe, the tee pipe having a water inlet pipe, a first water outlet pipe, and a second water outlet pipe, the first water outlet pipe having a first water outlet end, the second water outlet pipe having a second water outlet end, the first water outlet end 5 of the first water outlet pipe communicating with the outer condensation chamber, and the second water outlet end of the second water outlet pipe communicating with the inner condensation chamber 3;

[0105] The first water outlet pipe is designed so that the water flowing out of the first water outlet pipe can be sprayed on the uppermost first rib 61 and / or the uppermost second rib 62 in the outer condensation chamber 4;

[0106] The second water outlet pipe is designed so that the water flowing out through the second water outlet pipe can be sprayed onto the inner guide rib located at the uppermost position in the inner condensation chamber 3 .

[0107] In the embodiment of the present invention, by using a three-way pipe to distribute the cooling water, it can be ensured that the cooling water in the inner condensation chamber 3 and the outer condensation chamber is evenly distributed.
