Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and in particular to a clothing processing equipment. Background Art

[0002] The drying system of a condensing washer-dryer is generally divided into two main sections: the evaporation section and the condensation section. The evaporation section uses electric heating and a fan to blow dry, hot air into the washing machine drum to evaporate moisture from the clothes. The condensation section uses a fan to draw the evaporated, hot, moist air into the condensation duct for condensation.

[0003] Currently, most of the water-cooled washer-dryers on the market have separate condensation ducts. During the drying process, only one condensation duct cannot completely condense the hot and humid air in the washing machine drum that evaporates the clothes. This results in most water-cooled washer-dryers on the market having a long drying time and a high moisture content in the clothes, which greatly affects the user experience.

[0004] There are a small number of models on the market that use a condenser and outer cylinder that are post-injected into one. However, due to the low heat exchange efficiency between condensed water and moist hot air, there are defects such as low condensation efficiency and low cooling water utilization rate.

DETAILED DESCRIPTION

[0059] 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.

[0060] Existing clothing processing equipment suffers from low heat exchange efficiency between condensed water and hot, moist air, low condensation efficiency, and low cooling water utilization. The clothing processing equipment in the embodiments of the present invention eliminates the traditional condensation air duct and relies on double-sided condensation on both the inner and outer walls of the outer drum to achieve increased heat exchange efficiency.

[0061] The following is combined with Figure 1-7 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0062] Example

[0063] like Figure 1-Figure 7 As shown, this embodiment provides a clothes processing device, including:

[0064] The outer cylinder 1 has an inner wall surface 11 and an outer wall surface 12 formed opposite to each other on its bottom wall;

[0065] Inner cylinder {not shown in the figure}, the inner cylinder is pivotally arranged in the outer cylinder 1;

[0066] The inner condensing air duct is formed between the outer wall surface of the bottom wall of the inner cylinder and the inner wall surface 11 of the bottom wall of the outer cylinder 1;

[0067] The outer condensation air duct is formed on the outer side of the outer wall surface 11 of the bottom wall of the outer cylinder 1;

[0068] The outer condensation air duct is provided with an air inlet 13 at the lower part of the bottom wall of the outer cylinder 1. One end of the air inlet 13 is connected to the lower part of the inner condensation air duct, and the other end is connected to the lower part of the outer condensation air duct.

[0069] The air outlet 15 is provided at the top of the outer tube 1 and has an air inlet end. A portion of the air inlet end of the air outlet 15 is connected to the inner condensation air duct, and another portion is connected to the outer condensation air duct.

[0070] The air inlet 13 is located below the air outlet 15. The dry air condensed by the inner condensation duct and the dry air condensed by the outer condensation duct are mixed at the air outlet 15 and then discharged through the air outlet 15.

[0071] A first water inlet is provided above the inner condensation air duct, and the first water inlet is used to flow cooling water into the inner condensation air duct. A second water inlet is provided above the outer condensation air duct, and the second water inlet is used to flow cooling water into the outer condensation air duct.

[0072] It is worth noting that the cooling water mentioned in the embodiment of the present invention can be condensed water after condensation, or it can be tap water from a water pipe. As long as the condensed water injected into the air duct can condense the hot and humid air in the air duct, the embodiment of the present invention does not make specific restrictions on the temperature and source of the cooling water.

[0073] The clothes processing device in the embodiment of the present invention eliminates the traditional condensation air duct and relies on the inner wall surface 11 and the outer wall surface 12 of the outer drum 1 to perform double-sided condensation to achieve increased heat exchange efficiency.

[0074] Specifically, when the clothing processing device performs the clothing drying program, part of the hot and humid air in the clothing processing device enters the inner condensation duct between the inner and outer tubes 1 through the air holes on the inner tube, and the other part enters the outer condensation duct formed by the outer wall of the outer tube 1 and the sealing cover 2 through the air inlet 13 on the bottom wall of the outer tube 1. The water inlet device 3 respectively introduces water into the inner condensation duct and the outer condensation duct, thereby condensing the hot and humid air entering the inner condensation duct and the outer condensation duct. Since the traditional condensation duct at the rear of the outer tube is eliminated and the outer wall surface 12 of the outer tube 1 is used as the condensation surface, compared with the traditional condensation duct at the rear of the outer tube 1, the condensation surface is larger when condensing the hot and humid gas, and the heat exchange efficiency is higher.

[0075] Further, such as Figure 2 and Figure 3 As shown, inner guide ribs 4 are provided on the inner wall surface 11 of the outer cylinder 1, and outer guide ribs 5 are provided on the outer wall surface 12 of the outer cylinder 1. The inner guide ribs 4 protrude toward the air cavity of the inner condensation air duct, and the outer guide ribs 5 protrude toward the air cavity of the outer condensation air duct.

[0076] The water flowing into the inner condensation air duct through the first water inlet 31 can be guided by the inner guide ribs 4 , and the water flowing into the outer condensation air duct through the second water inlet 32 ​​can be guided by the outer guide ribs 5 .

[0077] In the embodiment of the present invention, guide ribs {inner guide ribs 4 and outer guide ribs 5} are provided on the inner wall surface 11 and the outer wall surface 12 of the outer tube 1. When the water in the water inlet device is injected into the inner condensation air duct and the outer condensation air duct, it can be guided by the inner guide ribs 4 and the outer guide ribs 5, thereby increasing the flow time of the condensed water in the air duct cavity. At the same time, the condensed water can form a condensation water curtain on the inner and outer sides of the outer tube 1. The condensation water curtain can occupy more than 70 percent of the area of ​​the rear wall of the outer tube 1. Compared with the traditional condensation air duct, the condensation area is larger and the heat exchange efficiency is higher.

[0078] In any of the above embodiments, the inner guide ribs and the outer guide ribs are arranged alternately relative to the bottom wall of the outer cylinder 1 .

[0079] The protruding height of the inner guide rib 4 is smaller than the protruding height of the outer guide rib 5 .

[0080] The reason why the inner guide ribs 4 and the outer guide ribs 5 are staggered 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 generating thermal resistance, and improve the condensation heat exchange effect of the two condensation surfaces of the rear wall of the outer tube 1.

[0081] The reason why the protruding height of the inner guide rib 4 is set to be smaller than the protruding height of the outer guide rib 5 in the embodiment of the present invention is because the inner drum of the clothing processing device has a raised surface. In order to prevent the condensed water in the inner condensation duct from flowing to the bearing oil seal, the protruding height of the inner guide rib needs to be set to be shortened so that the condensed water only flows on the inner guide rib.

[0082] In any of the above embodiments, Figure 3 As shown, a bearing mounting portion 14 is provided in the rear middle area of ​​the outer cylinder 1 , and multiple groups of outer guide ribs 5 are provided, and the multiple groups of outer guide ribs 5 are distributed on the outer periphery of the bearing mounting portion 14 .

[0083] In the embodiment of the present invention, by arranging multiple groups of outer guide ribs 5 in the outer guide cavity, the condensed water can fully flow in the outer condensation air duct, thereby improving the heat exchange effect between the condensed water and the hot and humid air.

[0084] Specifically, such as Figure 3 As shown, the clothes processing device includes a water inlet device, the water inlet device 3 is provided with the above-mentioned first water inlet 31 and second water inlet 32, the water inlet device 3 is provided at the rear top end of the outer tub 1, and the air inlet 13 is provided at the rear bottom end of the outer tub 1;

[0085] Multiple groups of external guide ribs 5 are distributed from top to bottom between the water inlet device 3 and the air inlet 13;

[0086] The multiple groups of outer guide ribs 5 distributed from top to bottom are designed so that the water flow on the upper outer guide ribs can flow step by step into the lower outer guide ribs.

[0087] In the embodiment of the present invention, the water inlet device 3 and the air inlet 13 are arranged on the upper and lower sides of the rear part of the outer tube 1. When the air flow enters the external condensation air duct through the air inlet 13, the air flow flows upward. When the water inlet device 3 enters the external condensation air duct, the water flows downward. The upward-flowing air flow and the downward-flowing water flow can fully contact each other, thereby improving the heat exchange effect.

[0088] At the same time, multiple groups of external guide ribs 5 are arranged between the water inlet device 3 and the air inlet 13. When the downward-flowing water falls on the multiple groups of external guide ribs 5, a water curtain can be formed, so that it can fully contact the upward-flowing airflow, thereby further improving the heat exchange effect between the humid and hot airflow and the condensed water, and improving the condensation efficiency.

[0089] In any of the above embodiments, the multiple groups of external guide ribs include at least a first external guide rib 51 located below the water inlet of the water inlet device 3 and above the bearing mounting portion 14, two third external guide ribs located above the air inlet 13 and spaced apart and located below the left and right sides of the bearing mounting portion 14, and a fourth external guide rib located above the air inlet 13 and below the two third external guide ribs and opposite to the spaced apart edges.

[0090] In any of the above embodiments, Figure 3 As shown, the vertical plane where the axis of the outer cylinder 1 is located is the central axis plane of the outer cylinder;

[0091] The plurality of groups of outer guide ribs 5 include a first outer guide rib group 51 provided below the water inlet device 3, a fourth guide rib group 54 provided above the air inlet 13, and a second outer guide rib group 52 and a third outer guide rib group 53 between the first outer guide rib group 51 and the fourth outer guide rib group 54.

[0092] The first outer guide rib group 51 includes two first outer guide ribs symmetrically arranged with the central axis of the outer cylinder as the symmetry center. The first outer guide ribs are constructed in an arc shape, wherein one end of the two first outer guide ribs are connected, and the other ends of the two first outer guide ribs are arranged toward the second outer guide rib group 52;

[0093] The second outer guide rib group 52 includes two second outer guide ribs symmetrically arranged with the central axis of the outer cylinder as the center of symmetry. The second outer guide ribs are constructed in an arc shape and have a second outer guide surface arranged toward the free end of the first outer guide rib, wherein the second outer guide surface is concave toward the free end of the first outer guide rib. The second outer guide surface has a high point and a low point in its guide direction. With respect to the high point and the low point of the second outer guide surface, the free end of the first outer guide rib is arranged closer to the high point of the second outer guide surface.

[0094] The third outer guide rib group 53 includes two third outer guide ribs symmetrically arranged with the central axis of the outer cylinder as the symmetry center. The third outer guide ribs are constructed in an arc shape and are arranged below the second outer guide ribs. The third outer guide ribs have a third outer guide surface, wherein the concave direction of the third outer guide surface is the same as that of the second outer guide surface.

[0095] The fourth outer guide rib group 54 includes two fourth outer guide ribs symmetrically arranged with the central axis of the outer cylinder as the center of symmetry. The fourth outer guide rib is constructed in an arc shape. The fourth outer guide rib is arranged below the third outer guide rib. The fourth outer guide rib has a fourth outer guide surface, wherein the concave direction of the fourth outer guide surface is opposite to the concave direction of the third outer guide surface.

[0096] The reason why multiple groups of external guide ribs are arranged in the above manner in the embodiment of the present invention is that the condensed water can flow fully on multiple guide ribs. Specifically, for two adjacent external guide ribs in the height direction, the water flow on the upper guide rib can flow to the outer guide rib located below.

[0097] In any of the above embodiments, Figure 1 and Figure 5 As shown, the clothes processing device includes a sealing cover 2, which includes an annular cover plate 21 with a circular opening in the middle, and an annular outer cover 22 and an annular inner cover 23 radially protruding along the cover plate 21;

[0098] An annular outer condensation air duct is formed between the cover plate 21, the outer cover 22, the inner cover 23 and the outer wall surface 12 of the outer cylinder 1;

[0099] The inner cover 23 is disposed around the outer periphery of the bearing mounting portion 14 .

[0100] In the embodiment of the present invention, an annular sealing cover 2 is adopted. Through the cooperation between the cover plate 21, the outer cover 22, the inner cover 23 and the outer wall surface 12 of the outer cylinder 1, a closed external condensation air duct can be formed. On the other hand, by surrounding the inner cover 23 on the outer periphery of the bearing mounting portion 14, the condensed water in the external condensation air duct can be prevented from entering the bearing mounting portion 14. That is, in the embodiment of the present invention, the outer wall area of ​​the outer cylinder 1 is fully utilized as the condensation surface to condense the hot and humid airflow by adopting the annular sealing cover 2.

[0101] In any of the above embodiments, Figure 3 and Figure 6 As shown, a plurality of guide holes 511 are provided on the outer guide ribs, wherein the downward projection of the guide holes 511 in the height direction of the outer cylinder 1 coincides with the inner cover 23 .

[0102] Preferably, the guide holes 511 are arranged on the first outer guide rib group 51. When the water inlet device 3 feeds water into the external condensation air duct, the water flow first falls on the first outer guide rib group 51 and flows out through the guide holes 511 on the first outer guide rib group 51. The outflowing condensed water flows on the surface of the inner cover 23 on the sealing cover 2, thereby further increasing the heat exchange area and improving the heat exchange effect.

[0103] In any of the above embodiments, Figure 5 and Figure 7 As shown, the outer guide rib 5 is formed with a convex surface in its convex direction, and the convex surface is spaced apart from the plate surface of the cover plate 21 by a distance.

[0104] The reason why the convex surface of the outer guide rib 5 is set to have a certain distance from the plate surface of the cover plate 21 in the embodiment of the present invention is to increase the flow speed of the moist hot airflow in the external condensation duct. If the convex surface of the outer guide rib 5 is set to contact the cover plate, it will affect the upward flow speed of the airflow, thereby affecting the heat exchange effect between the airflow and the condensed water.

[0105] As described above, since there is a gap between the convex surface of the outer guide rib 5 and the cover plate 21 of the sealing cover 2 , the water flowing through the guide holes 511 on the outer guide rib 5 cannot completely cover the inner cover 23 of the sealing cover 2 .

[0106] like Figure 5 and Figure 7 As shown, in order to allow the condensed water to fully cover the inner cover surface of the sealing cover 2, a water outlet hole 25 is provided on the surface of the inner cover 23 in the embodiment of the present invention.

[0107] Specifically, such as Figure 5 As shown, the inner cover 23 has an outer cover surface facing the outer cover 22 and an inner cover surface facing away from the outer cover;

[0108] The sealing cover 2 further includes a condensation ring 24 provided on the inner cover surface. The interior of the condensation ring 24 is constructed as a cavity, and a plurality of water outlet holes 25 are uniformly distributed on the outer cover surface and communicate with the cavity of the condensation ring 24.

[0109] The condensation ring 24 is also provided with a water inlet 26, which is used to inject water into the condensation ring 24;

[0110] The downward projection of the outer guide rib 5 in the height direction of the outer cylinder 1 does not coincide with the water outlet hole 25 on the outer cover surface.

[0111] The condensed water enters the condensation ring 24 through the water inlet 26 of the condensation ring 24, and is sprayed toward the sealing area where the sealing cover 2 is connected to the rear outer tube 1 through the condensation outlet hole 25 on the condensation ring 24. This structure can further improve the heat exchange efficiency.

[0112] At the same time, since the downward projection of the outer guide rib 5 in the height direction of the outer cylinder 1 does not coincide with the water outlet hole 25 on the outer cover surface, the condensed water can fully cover the inner cover surface of the sealing cover 2 {part of the surface of the inner cover 23 is covered by the condensed water flowing down from the outer guide rib 5, and another part of the surface of the inner cover 23 is covered by the condensed water sprayed from the water outlet hole 25}, thereby improving the heat exchange efficiency.

[0113] In any of the above embodiments, Figure 1-Figure 3 As shown, the clothes processing device further includes a heating air duct 6, the heating air duct 6 has an air inlet end, and the air inlet end of the heating air duct 6 is connected to the air outlet end of the air outlet 15;

[0114] The heating air duct 6 also has an air outlet end, and the air outlet end of the heating air duct 6 is connected to the inner cylinder;

[0115] The heating air duct 6 is provided with a drying fan and a heating device, wherein the drying fan is arranged near the air inlet end of the heating air duct 6, and the heating device is arranged on the air outlet side of the drying fan, for heating the drying air flow sucked into the heating air duct 6;

[0116] Under the action of the drying fan, the air flow entering the inner condensation air duct and the outer condensation air duct is sucked into the heating air duct from the air outlet, and returns to the inner drum after being heated.

[0117] In any of the above embodiments, the flow area of ​​the air inlet is larger than the flow area at the connection point between the air outlet and the inner condensation air duct, and the flow area at the connection point between the air outlet and the outer condensation air duct is larger than the area of ​​the air inlet.

[0118] In the embodiment of the present invention, by setting the flow cotton knot of the air inlet 13 to be larger than the flow area at the connection point between the air outlet and the inner condensation air duct, the air flow rate entering the outer condensation air duct can be increased, thereby improving the condensation effect of the humid and hot air flow.

[0119] In any of the above embodiments, the first water inlet is designed so that water flowing out through the first water inlet can be sprayed onto the inner wall surface of the bottom wall of the outer cylinder to form a water film on the inner wall surface;

[0120] The second water inlet is designed so that the water flowing out through the second water inlet can be sprayed onto the outer wall surface of the bottom wall of the outer cylinder to form a water film on the outer wall surface.

[0121] A water film can be formed on the wall surface of the outer cylinder 1 in the embodiment of the present invention. On the one hand, the formation of the water film can save the utilization of water resources, on the other hand, it can increase the condensation area, and on the other hand, the formed water film can also collect hair debris in the air duct to prevent the hair debris from being sucked into the drying fan.

[0122] The following combination Figure 1-Figure 7 The clothes processing device in the embodiment of the present invention is described in detail:

[0123] like Figure 2 and Figure 3 As shown, the bottom wall of the outer cylinder 1 has two sides, namely the inner wall surface 11 and the outer wall surface 12 of the outer cylinder. The lower end of the outer cylinder 1 has an air inlet 13. Under the action of the drying centrifugal fan, part of the hot and humid air will flow through the air inlet 13 to the outer wall surface 12 of the outer cylinder 1. The outer wall surface 12 of the outer cylinder 1 has an outer guide rib 5 with a relatively high protrusion height. The upper part of the outer guide rib 5 is provided with a guide hole 511. When the condensed water enters the water inlet device 3 through the condensation pipe, as shown in FIG. Figure 3As shown, the water outlet on the water inlet device 3 directs water toward the outer guide ribs 5 located at the top. Due to the interaction between the outer guide ribs 5 and the guide holes 511, a condensed water curtain is formed on the outer wall 12 of the outer cylinder 1. The condensed water curtain is able to fully contact the hot and humid air, thereby achieving a high heat exchange efficiency.

[0124] like Figure 2 As shown, on the inner wall of outer drum 1, air inlet 13 cannot completely direct the hot and humid air toward outer wall 12. Most of the hot and humid air remains on inner wall 11. Inner guide ribs 4 are also provided on inner wall 11 of outer drum 1. However, due to the presence of the inner drum of the washer-dryer, the protrusion height of inner guide ribs 4 is much lower than the protrusion height of outer guide ribs 5 on outer wall 12 of outer drum 1. Therefore, no guide holes 511 are provided on inner guide ribs 4. The same condensation inlet logic as on outer wall 12 of outer drum 1 is used. Condensed water forms a large condensation water curtain on inner guide ribs 4. The hot and humid air contacts the condensation water curtain, greatly improving heat exchange efficiency. The condensed air is then blown through outlet 15 by the drying centrifugal fan to the heating air duct 6. After heating, it is blown into the inner drum, completing the drying cycle.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow from the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
