Description

Technical Field

[0001] The present invention relates to the technical field of clothing care, and particularly provides a clothing care device. Background Art

[0002] Nowadays, with the continuous improvement of people's living standards, people are constantly pursuing a higher quality of life, and clothing care machines that use high-temperature steam to remove wrinkles from clothes are becoming more and more popular among people. The water supply box of the clothing care machine is connected to the inlet of the steam generator, and the outlet of the steam generator is communicated with the clothing care cavity of the clothing care machine through a conduit. A gas-liquid separator is connected in series on the conduit.

[0003] When caring for clothes, the water supply box supplies water into the steam generator, and the steam generator works to generate high-temperature water vapor. The high-temperature water vapor is transported through the conduit to the clothing care cavity of the clothing care machine to wet and soften the clothes, so that the clothes have a certain water content and softness. The clothing fibers absorb water, and under the dual action of high-temperature softening and swinging, the fibers at the wrinkled parts of the clothes will stretch, so as to achieve the effect of wrinkle removal and care. Then, the clothes are dried by high-temperature hot dry air.

[0004] Due to the long conduit, a part of the water vapor reaching the gas-liquid separator condenses into suspended small droplets, and the temperature of the water vapor also decreases. During the process of the water vapor separated by the gas-liquid separator flowing to the outlet end of the conduit, since the temperature of the conduit is lower than that of the water vapor, a part of the water vapor will further condense on the inner wall of the conduit to form droplets. When the water vapor is blown from the outlet end of the conduit into the clothing care cavity, at least a part of the condensed water on the inner wall of the conduit will move to the outlet end of the conduit along with the air flow and generate a large number of bubbles. The bubbles enter the clothing care cavity and continuously expand to the limit volume and then burst. During the bursting process of the bubbles, a relatively large noise is generated, which affects the user experience.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above technical problems, that is, to solve the problem that a large number of bubbles generated at the outlet end of the conduit in the existing clothing care machine enter the clothing care cavity and burst, generating relatively large noise.

[0007] The present invention provides a clothing care device, which includes a box body, a clothing care cavity, a steam generator and a water-vapor separator arranged in the box body. The water-vapor separator includes a housing, a pressure reduction cavity is arranged in the housing, the top of the housing has an outlet communicating with the pressure reduction cavity, the outlet is exposed in the clothing care cavity, the bottom of the housing has an inlet, the outlet of the steam generator is communicated with the first end of a conduit, the second end of the conduit is communicated with the pressure reduction cavity through the inlet, and an anti-foaming structure is arranged at the second end of the conduit.

[0008] In a preferred technical solution of the above-mentioned clothing care device, the anti-foaming structure includes a grille plate covering the second end of the conduit, and a plurality of spike structures extending towards the inside of the conduit are formed on the side surface of the grille plate facing the conduit.

[0009] In a preferred technical solution of the above-mentioned clothing care device, the inner surface of the top of the housing at least above the inlet extends obliquely upwards in the direction close to the outlet; and / or one side edge of the outlet extends obliquely upwards in the direction close to the opposite side edge to form an extension plate.

[0010] In a preferred technical solution of the above-mentioned clothing care device, a heating device is arranged on the outer wall of the conduit.

[0011] In a preferred technical solution of the above-mentioned clothing care device, a reflux port is arranged at the bottom of the housing, and the reflux port is connected to a pipe section of the conduit above the heating device through a reflux pipe.

[0012] In a preferred technical solution of the above-mentioned clothing care device, the conduit includes an inner pipe and an outer pipe arranged in a nested manner, and a first channel communicating the outlet of the steam generator with the pressure reduction cavity is formed in the inner pipe.

[0013] In a preferred technical solution of the above-mentioned clothing care device, a vacuum cavity is formed between the inner pipe and the outer pipe.

[0014] In a preferred technical solution of the above-mentioned clothing care device, a second channel is formed between the inner pipe and the outer pipe, a reflux port is arranged at the bottom of the housing, the upper end of the second channel is communicated with the reflux port, the lower end of the second channel is connected to the outlet of the steam generator, and the flow area of the second channel is not greater than one-half of the flow area of the first channel.

[0015] In a preferred technical solution of the above-mentioned clothing care device, the clothing care device is arranged such that the outlet of the steam generator can be selectively communicated with the lower end of the first channel and the lower end of the second channel.

[0016] In the preferred technical solution of the above-mentioned clothing care device, a heating device is provided on the outer wall of the second channel.

[0017] In the case of adopting the above technical solution, the clothing care device includes a box body, a clothing care cavity, a steam generator and a water-vapor separator arranged in the box body. The water-vapor separator includes a housing, a decompression cavity is arranged in the housing, the top of the housing has an outlet communicated with the decompression cavity, the outlet is exposed in the clothing care cavity, the bottom of the housing has an inlet, the outlet of the steam generator is communicated with the first end of a conduit, the second end of the conduit is communicated with the decompression cavity through the inlet, and an anti-foaming structure is arranged at the second end of the conduit.

[0018] With such a setting, the bubbles generated at the outlet end of the conduit are affected by the anti-foaming structure during the process of flowing from the outlet end into the water-vapor separator, which can avoid the situation that a large number of bubbles enter the gas-liquid separator, and further avoid the bubbles entering the clothing care cavity from the outlet of the water-vapor separator. The decompression cavity of the water-vapor separator makes the bubbles rapidly expand at the end position of the anti-foaming structure, making the anti-foaming structure more effectively eliminate the bubbles. In the water-vapor separator, water vapor and condensed water droplets are separated, and the water vapor directly enters the clothing care cavity, avoiding the situation that in the existing clothing care machine, a large amount of condensed water is generated during the continuous flow of the water vapor passing through the water-vapor separator in the conduit, and a large number of bubbles are generated at the outlet end of the conduit, resulting in a large amount of bubbles entering the clothing care cavity and bursting to generate a large noise, thus optimizing the user experience.

[0019] Preferably, the anti-foaming structure includes a grille plate covering the second end of the conduit, and a plurality of spike structures extending towards the inside of the conduit are formed on the side surface of the grille plate facing the conduit.

[0020] With such a setting, the bubbles flowing from the second end of the conduit towards the water-vapor separator along the air flow are squeezed and burst by the grille plate, and the spike structures on the side surface of the grille plate facing the conduit further accelerate the bursting of the foam, so that most of the bubbles are punctured before flowing through the grille holes of the grille plate in the second end of the conduit, and most of the bubbles are eliminated in the second end of the conduit, further reducing the noise generated by the bursting of the bubbles.

[0021] Preferably, the inner surface of the top of the housing at least above the inlet extends obliquely upwards in the direction close to the outlet.

[0022] With such a setting, a small amount of condensed water droplets generated on the inner wall of the top of the housing can flow down along the inner wall of the side more smoothly, reducing the risk that the droplets on the top inner wall are blown by the air flow to the outlet on the housing to form bubbles when dripping from top to bottom, thereby reducing the risk of bubbles entering the clothing care cavity. In addition, this can also reduce the ratio of the inner wall area of the housing to the volume of the decompression cavity in the housing, so as to reduce the generation of condensed water on the basis of ensuring the water vapor separation effect and reduce the loss of water vapor.

[0023] Preferably, one side edge of the outlet extends obliquely upward in the direction close to the opposite side edge with an extension plate.

[0024] With such a setting, the trace condensed water droplets mixed in the air flow hit the extension plate during the process of flowing out from the outlet of the housing and flow back to the decompression cavity of the water vapor separator along the side wall of the extension plate, reducing the influence of this part of the condensed water droplets on the temperature of the water vapor entering the clothing care cavity.

[0025] Preferably, a heating device is arranged on the outer wall of the conduit.

[0026] With such a setting, after the condensed water in the water vapor separator flows into the conduit along the reverse direction of the air flow from the inlet at the bottom of the housing of the water vapor separator, the heat generated by the heating device on the outer wall of the conduit is transferred to this part of the condensed water, making this part of the condensed water turn back into water vapor and enter the water vapor separator along the conduit, and then enter the clothing care cavity from the outlet of the water vapor separator, avoiding the influence on the amount of water vapor entering the clothing care cavity due to a part of the originally generated water vapor turning into condensed water, ensuring the amount of water vapor entering the clothing care cavity, and thus improving the effect of clothing wrinkle removal and care. In addition, the heating device can further heat the flowing water vapor to ensure the temperature of the water vapor entering the clothing care cavity.

[0027] Preferably, a return port is arranged at the bottom of the housing, and the return port is connected to the pipe section of the conduit above the heating device through a return pipe.

[0028] With such a setting, the condensed water separated in the water vapor separator flows back to the pipe section of the conduit above the heating device through the return pipe, and then this part of the condensed water is heated by the heating device to turn it into water vapor, avoiding the influence on the temperature of the water vapor conveyed in the conduit when the condensed water separated in the water vapor separator flows back along the conduit, further increasing the temperature of the water vapor entering the clothing care cavity, and also being able to heat the returned condensed water to turn it into water vapor.

[0029] Preferably, the conduit includes an inner pipe and an outer pipe arranged in a nested manner, and a first channel communicating the outlet of the steam generator and the decompression cavity is formed in the inner pipe.

[0030] Through such a setting, the influence of the environment outside the conduit on the temperature of the inner tube of the conduit is reduced, thereby reducing the occurrence of the situation where water vapor condenses into droplets during the flow in the conduit due to the relatively low temperature of the conduit, and more effectively ensuring the amount of water vapor entering the clothing care cavity.

[0031] Preferably, a vacuum cavity is formed between the inner tube and the outer tube.

[0032] Through such a setting, the influence of the environment outside the conduit on the temperature of the inner tube of the conduit is further reduced, and further reduces the occurrence of the situation where water vapor condenses into droplets during the flow in the conduit due to the relatively low temperature of the conduit.

[0033] Preferably, a second channel is formed between the inner tube and the outer tube, a return port is provided at the bottom of the housing, the upper end of the second channel is communicated with the return port, the lower end of the second channel is connected to the outlet of the steam generator, and the flow area of the second channel is not greater than one-half of the flow area of the first channel.

[0034] Through such a setting, it is possible to reduce the influence of the environment outside the conduit on the temperature of the inner tube of the conduit by the method of "setting the conduit as a double-layer tube", and to avoid the influence of the condensed water separated in the water vapor separator on the temperature of the water vapor transported in the conduit when flowing back along the conduit, and to utilize the returned condensed water to increase the temperature of the conduit, and further reduce the occurrence of the situation where the water vapor in the conduit contacts the inner wall of the conduit and condenses into droplets.

[0035] Preferably, the clothing care device is set such that the outlet of the steam generator can be selectively communicated with the lower end of the first channel and the lower end of the second channel.

[0036] Through such a setting, during use, within a period of time (such as 10 s) when the steam generator starts to work, the outlet of the steam generator can be communicated with the lower end of the second channel and not with the lower end of the first channel, and the water vapor flows along the second channel to the water vapor separator. During this process, the high-temperature water vapor preheats the inner tube and the outer tube of the conduit. After preheating, the outlet of the steam generator is communicated with the lower end of the first channel and not with the lower end of the second channel, and the water vapor flows along the first channel to the water vapor separator and then flows into the clothing care cavity. That is to say, in this way, the inner tube and the outer tube of the conduit can be preheated by using the water vapor flowing into the second channel first, and then the water vapor is transported from the first channel to the water vapor separator and then to the clothing care cavity after passing through the water vapor separator, avoiding the situation where a large amount of condensed water is generated during the transportation of the water vapor in the conduit due to the relatively low temperature of the conduit.

[0037] Preferably, a heating device is provided on the outer wall of the second channel.

[0038] With such a setting, it is possible to heat the condensed water flowing back in the second channel to turn it into water vapor, thereby more effectively maintaining the conduit at a higher temperature and reducing the heat loss of the water vapor in the conduit during transportation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] First of all, those skilled in the art should understand that the embodiments described below are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0046] It should be noted that in the description of the invention, the terms indicating directions or positional relationships such as "left" and "right" are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0047] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a direct connection or an indirect connection. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to specific circumstances.

[0048] Based on the problem that a large number of bubbles generated at the outlet end of the conduit in the existing clothing care machine mentioned in the background art burst after entering the clothing care chamber, resulting in relatively large noise, the present invention provides a clothing care device. The clothing care device includes a box body, a clothing care chamber, a steam generator, and a water-vapor separator disposed within the box body. The water-vapor separator includes a housing, a decompression chamber is provided within the housing, the top of the housing has an outlet communicating with the decompression chamber, the outlet is exposed within the clothing care chamber, the bottom of the housing has an inlet, the outlet of the steam generator is communicated with the first end of the conduit, the second end of the conduit is communicated with the decompression chamber through the inlet, and an anti-foaming structure is provided at the second end of the conduit.

[0049] Through such an arrangement, the bubbles generated at the outlet end of the conduit are affected by the anti-foaming structure during the process of flowing from the outlet end into the water-vapor separator, which can avoid the occurrence of a large number of bubbles entering the gas-liquid separator, and further avoid the bubbles entering the clothing care chamber from the outlet of the water-vapor separator. The decompression chamber of the water-vapor separator causes the bubbles to rapidly expand at the end position of the anti-foaming structure, making the anti-foaming structure more effectively eliminate the bubbles. Within the water-vapor separator, water vapor and condensed water droplets are separated, and the water vapor directly enters the clothing care chamber, avoiding the situation in the existing clothing care machine where a large number of bubbles are generated at the outlet end of the conduit after more condensed water is generated during the continuous flow of the water vapor passing through the water-vapor separator in the conduit, and then a large number of bubbles enter the clothing care chamber and burst, generating relatively large noise, thus optimizing the user experience.

[0050] The following refers to Figures 1 to 3 to introduce the present invention. Among them, Figure 1 is a schematic structural diagram of an assembly of the water-vapor separator and the conduit of a clothing care device according to an embodiment of the present invention; Figure 2 is a partially sectional schematic diagram of an assembly of the water-vapor separator and the conduit of a clothing care device according to an embodiment of the present invention; Figure 3 is a schematic structural diagram of the anti-foaming structure in the water-vapor separator of a clothing care device according to an embodiment of the present invention.

[0051] In a specific embodiment of the present invention, the clothing care device includes a box body, a clothing care chamber, a steam generator, and a water-vapor separator disposed within the box body. The structures and layouts of the box body, the clothing care chamber, the steam generator, and the water-vapor separator are common knowledge of the clothing care device and will not be elaborated herein.

[0052] As Figure 1 and Figure 2As shown in the figure, the steam separator includes a housing 1, and the housing 1 includes a top plate 11 at the top, side plates 12 around the periphery, and a bottom plate 13 at the bottom. The top plate 11, side plates 12, and bottom plate 13 enclose a decompression chamber 14 inside the housing 1 (compared with the volume of the passage in the conduit 2, the volume of the decompression chamber 14 suddenly increases, so that the gas flowing from the conduit 2 into the decompression chamber 14 can be decompressed). The top plate 11 of the housing 1 includes a flat plate 111 and an inclined plate 112 connected in sequence from right to left. The inclined plate 112 extends upwardly and obliquely in the direction from left to right. An outlet 1111 that penetrates through the flat plate 111 in its thickness direction and communicates with the decompression chamber 14 is formed on the flat plate 111. The outlet 1111 is exposed in the clothing care chamber (not shown in the figure). An arc-shaped extension plate 15 extends obliquely upward along the direction close to the left edge from the right edge of the outlet 1111. An inlet 131 that penetrates through the bottom plate 13 in its thickness direction is formed in the area directly below the inclined plate 112 on the bottom plate 13. A return port 132 that penetrates through the bottom plate 13 in its thickness direction is formed in the area directly below the flat plate 111 on the bottom plate 13. The outlet of the steam generator is communicated with the lower end of the conduit 2 (not shown in the figure). The upper end of the conduit 2 passes through the inlet 131 and extends into the decompression chamber 14 to communicate with the decompression chamber 14. An anti-foaming structure 3 is provided at the upper end of the conduit 2. An electric heating coil 4 serving as a heating device is sleeved on the pipe section of the conduit 2 located outside the decompression chamber 14 and close to the housing 1. The return port 132 is connected to the steam generator through a return pipe 5 (not shown in the figure).

[0053] As Figure 3 shown, the anti-foaming structure 3 includes a grille plate 31 and a plurality of spike structures 32 extending downward on the lower surface of the grille plate 31. The grille plate 31 covers the upper end of the conduit 2, and the spike structures 32 extend toward the inside of the conduit 2.

[0054] During use, the steam generator generates high-temperature water vapor, which flows from the outlet of the steam generator into the conduit 2 and flows along the conduit 2 towards the water-vapor separator. Before the water vapor in the conduit 2 flows through the position where the electric heating coil 4 is located, a small amount of water vapor encounters the wall of the conduit 2 with a lower temperature and condenses into condensate droplets. Part of the condensate droplets will flow down along the inner wall of the conduit 2 into the steam generator, and part of the condensate droplets will flow with the air current. When the water vapor in the conduit 2 flows through the position where the electric heating coil 4 is located, its temperature rises after being heated by the electric heating coil 4. Part of the condensate droplets mixed in the air current are heated and vaporized into water vapor, and part of the water condensate droplets condense on the inner wall at the upper end of the conduit 2 and generate bubbles at the upper end of the conduit 2 as the air current blows out. Most of the bubbles encounter the spiky structure 32 and burst inside the upper end of the conduit 2. A small number of bubbles expand as the air pressure in the decompression chamber 14 decreases during the process of passing through the grid holes on the grid plate 31. The wall thickness of the expanded bubbles becomes thinner and is squeezed by the edge of the grid holes and bursts. A small number of bubbles continue to expand in the decompression chamber 14 after passing through the grid holes and burst when reaching the limit. Part of the condensate droplets mixed in the air current adhere to the inner wall of the housing 1 (especially the inner wall of the inclined plate 112) during the process of flowing out with the air current, and the adhered condensate droplets flow down along the inner wall and flow out from the outlet 1111. The air current flowing out contacts the extension plate 15, and the condensate droplets mixed in the air current impact the extension plate 15 and flow back into the decompression chamber 14 of the water-vapor separator along the side wall of the extension plate 15. The condensate droplets flow into the return pipe 5 through the return port 132 on the bottom plate 13 and finally flow back to the steam generator through the return pipe 5.

[0055] Through the setting of the above structure, the generation of bubbles can be reduced, and the bubbles can be eliminated before entering the clothing care chamber, avoiding the situation that a large number of bubbles are generated at the outlet end of the conduit due to the generation of more condensate water during the continuous flow of the water vapor passing through the water-vapor separator in the existing clothing care machine, resulting in a large number of bubbles entering the clothing care chamber and bursting to generate a large amount of noise, thus optimizing the user experience.

[0056] The top plate 11 of the housing 1 is set to include a flat plate 111 and an inclined plate 112 connected in sequence from right to left. The inclined plate 112 extends upward obliquely in the direction from left to right, which can reduce the ratio of the inner wall area of the housing 1 to the volume of the decompression chamber 14 in the housing 1, so as to reduce the generation of condensate water and the loss of water vapor on the basis of ensuring the water-vapor separation effect. Through the cooperation of the grid plate 31 and the spiky structure 32, the bubbles generated at the upper end of the conduit 2 can be eliminated more effectively.

[0057] Through the arrangement of the extension plate 15, the trace condensate droplets mixed in the air flow collide with the extension plate 15 during the process of flowing out from the outlet 1111 of the housing 1 and flow back into the decompression chamber 14 of the water vapor separator along the side wall of the extension plate 15, reducing the influence of this part of the condensate droplets on the temperature of the water vapor entering the clothing care chamber.

[0058] Through the arrangement of the electric heating coil 4, the condensate flowing downward along the inner wall of the conduit 2 can be re-converted into water vapor and enter the water vapor separator along the conduit 2, and then enter the clothing care chamber from the outlet 1111 of the water vapor separator. This avoids the influence on the amount of water vapor entering the clothing care chamber caused by a part of the originally generated water vapor turning into condensate, ensures the amount of water vapor entering the clothing care chamber, and further improves the effect of clothing wrinkle removal and care. In addition, the electric heating coil 4 can further heat the flowing water vapor to ensure the temperature of the water vapor entering the clothing care chamber.

[0059] The upper end of the conduit 2 passes through the inlet 131 and extends into the decompression chamber 14 to communicate with the decompression chamber 14. A return port 132 penetrating through in the thickness direction is formed in the region of the bottom plate 13 directly below the flat plate 111. The return port 132 is connected to the steam generator through a return pipe 5. That is to say, the upper end of the conduit 2 is higher than the return port 132, so that the condensate in the decompression chamber 14 of the water vapor separator flows back to the steam generator through the return port 132 and the return pipe 5, avoiding the influence of the condensate separated in the water vapor separator on the temperature of the water vapor conveyed in the conduit 2 when flowing back along the conduit 2, and further improving the temperature of the water vapor entering the clothing care chamber.

[0060] In another more preferred embodiment, different from the above embodiment, the lower end of the return pipe 5 is connected to the pipe section of the conduit 2 above the electric heating coil 4. Through this arrangement, the returned condensate can be heated to turn it into water vapor.

[0061] It should be noted that the top plate 11 is arranged to include a flat plate 111 and an inclined plate 112 connected in sequence from right to left. The inclined plate 112 extends upwardly inclined in the direction from left to right. This is only a relatively preferred arrangement, and adjustments can be made in actual applications. For example, the top plate can be integrally arranged as a conical plate structure, and the outlet is arranged in the middle of the top plate. In addition, the defoaming structure 3 includes a grille plate 31 and a plurality of spike structures 32 extending downwardly on the lower surface of the grille plate 31. The grille plate 31 covers the upper end of the conduit 2, and the spike structures 32 extend towards the inside of the conduit 2. This is only a relatively preferred arrangement, and adjustments can be made in actual applications. For example, the defoaming structure only includes the grille plate 31, or the defoaming structure is arranged as spike structures formed on the inner wall of the upper end of the conduit 2. In addition, the electric heating coil 4 as a heating device is also a specific arrangement, and adjustments can be made in actual applications. For example, the heating device is an electric heating sheet arranged on the outer wall of the conduit 2 or an electric heating tube sleeved outside the conduit 2, etc.

[0062] In another relatively preferred embodiment, different from the above embodiment, the electric heating coil 4 is not provided, and the conduit 2 is arranged to include an inner tube and an outer tube nested with each other. A first channel communicating the outlet of the steam generator with the pressure reducing chamber 14 is formed inside the inner tube.

[0063] Through such an arrangement, the influence of the environment outside the conduit 2 on the temperature of the inner tube of the conduit 2 is reduced, thereby reducing the occurrence of the situation where water vapor condenses into droplets during the flow in the conduit 2 due to the relatively low temperature of the conduit 2, and more effectively ensuring the amount of water vapor entering the clothing care cavity.

[0064] Preferably, a vacuum cavity is formed between the inner tube and the outer tube. Through such an arrangement, the influence of the environment outside the conduit 2 on the temperature of the inner tube of the conduit 2 is further reduced, and further reduces the occurrence of the situation where water vapor condenses into droplets during the flow in the conduit 2 due to the relatively low temperature of the conduit.

[0065] In another relatively preferred embodiment, different from the above embodiment, the conduit 2 is arranged to include an inner tube and an outer tube nested with each other. A first channel communicating the outlet of the steam generator with the pressure reducing chamber 14 is formed inside the inner tube. A second channel is formed between the inner tube and the outer tube. The upper end of the second channel communicates with the return port, and the lower end of the second channel is connected to the outlet of the steam generator. The flow area of the second channel is not greater than one-half of the flow area of the first channel.

[0066] With such a setting, it is possible to reduce the influence of the environment outside the conduit 2 on the temperature of the inner tube of the conduit by means of "setting the conduit as a double-layer tube", and it is also possible to avoid the influence of the condensed water separated in the water vapor separator on the temperature of the water vapor transported in the conduit 2 when flowing back along the conduit 2. It is also possible to use the flowing-back condensed water to increase the temperature of the conduit 2, thereby reducing the occurrence of the situation where the water vapor in the conduit 2 contacts the inner wall of the conduit and condenses into droplets.

[0067] Preferably, the clothing care device is arranged such that the outlet of the steam generator can be selectively communicated with the lower end of the first channel and the lower end of the second channel. For example, the outlet of the steam generator is connected to the lower end of the first channel and the lower end of the second channel through a three-way valve.

[0068] With such a setting, during the use process, within a period of time (such as 10 s) when the steam generator starts to work, the outlet of the steam generator can be communicated with the lower end of the second channel and not with the lower end of the first channel. The water vapor flows along the second channel to the water vapor separator. During this process, the high-temperature water vapor preheats the inner tube and the outer tube of the conduit. After preheating, the outlet of the steam generator is communicated with the lower end of the first channel and not with the lower end of the second channel. The water vapor flows along the first channel to the water vapor separator and then flows into the clothing care cavity. That is to say, in this way, the inner tube and the outer tube of the conduit can be preheated by using the water vapor flowing into the second channel first, and then the water vapor can be transported from the first channel to the water vapor separator and then to the clothing care cavity after passing through the water vapor separator, avoiding the situation where more condensed water is generated during the transportation of the water vapor in the conduit due to the low temperature of the conduit.

[0069] Preferably, a heating device is arranged on the outer wall of the second channel.

[0070] With such a setting, it is possible to heat the condensed water flowing back in the second channel to turn it into water vapor, thereby more effectively maintaining the conduit at a higher temperature and reducing the heat dissipation of the water vapor in the conduit during transportation.
