Referring to the structures shown in fig. 2, 5, 6 and 7, the air duct upper cover 15 provided by the present invention includes an upper cover exhaust groove 17 for cooperating with a base exhaust groove 18 on an air duct base 16 to form an exhaust channel, and a cooling structure for cooling the air flowing through the upper cover exhaust groove 17 is disposed on a groove wall of the upper cover exhaust groove 17.

In the technical scheme, an upper cover exhaust groove 17 is formed on an air duct upper cover 15, and a cooling structure is arranged on the groove wall of the upper cover exhaust groove 17, so that after the air duct upper cover is applied to the clothes treatment device, the air duct upper cover 15 is connected with an air duct base 16, the upper cover exhaust groove 17 and a base exhaust groove 18 on the air duct base 16 form an exhaust channel, the exhaust channel can guide hot and humid air generated by drying clothes into a washing part of the clothes treatment device and condense through the washing part, meanwhile, when the hot and humid air flows through the exhaust channel, the cooling structure can condense the hot and humid air to reduce the moisture content in the hot and humid air, then, the air condensed through the washing part of the clothes treatment device can be heated again to dry the clothes, thereby realizing the circulation flow of the air and avoiding the direct discharge of the hot and humid air, the indoor air environment is prevented from being damp and hot, and the indoor comfort is improved to a certain degree.

Preferably, in the present embodiment, as shown in fig. 2, the cooling structure includes a cooling pipe 9, and a portion of the cooling pipe 9 is located in the upper cover exhaust groove 17. Thus, the hot and humid air flowing in the exhaust passage formed by the upper cover exhaust grooves 17 and the base exhaust grooves 18 contacts the portion of the cooling pipe 9 located in the exhaust passage and is condensed.

Of course, the cooling pipe 9 may be directly inserted into the upper cover exhaust groove 17, or, in this embodiment, as shown in fig. 2, a slit is formed on the groove top wall of the upper cover exhaust groove 17, and the cooling pipe 9 is disposed in the slit along the extending direction of the slit, that is, the axial direction of the cooling pipe 9 is the same as the extending direction of the slit, wherein the width of the slit is smaller than the diameter of the cooling pipe 9, so that a part of the pipe wall of the cooling pipe 9 disposed in the slit is located in the upper cover exhaust groove 17, and thus, the hot and humid air flowing in the exhaust passage will contact and be condensed on a part of the pipe wall of the cooling pipe 9 located in the exhaust passage, and thus, the pipe wall opening size can be reduced, and the possibility of leakage can be reduced.

Further, in order to further enhance the condensation effect of the hot and humid air, it is preferable that a spray hole is formed on a portion of the cooling pipe 9 located in the upper cover exhaust groove 17. For example, a nozzle hole is formed in a pipe section of the cooling pipe 9 inserted into the upper cover exhaust groove 17, or a nozzle hole is formed in a part of a pipe wall of the cooling pipe 9 located in the upper cover exhaust groove 17, and at this time, water in the cooling pipe 9 is sprayed in a mist or jet form through the nozzle hole, thereby cooling the hot and humid air flowing in the exhaust passage.

Of course, the number of the cooling pipes 9 may be one, or a plurality of such as 3 or 4, or other more. And a plurality of cooling tubes 9 may be connected to a plurality of water outlet ends of the cooling joint 36. For example, the cooling pipes 9 are arranged in a plurality in a side-by-side spaced manner, and the plurality of cooling pipes 9 are connected to a cooling joint 36 having a water inlet end and a plurality of water outlet ends, wherein one cooling pipe 9 is connected to one water outlet end.

Referring to fig. 2, 5-7, the duct upper cover 15 includes a U-shaped case portion 37, and an inner space of the U-shaped case portion 37 is formed as an upper cover discharge groove 17. Thus, the volume of the air duct upper cover 15 can be reduced, so that after the air duct upper cover 15 is disposed on the air duct base 16, the U-shaped shell portion 37 can avoid occupying too much of the air duct base 16, thereby facilitating formation of other structures on the air duct base 16, such as the air duct base vent hole 10 or the motor installation cavity 51.

In addition, as shown in fig. 2, the air duct upper cover 15 includes an air inlet casing portion including an air inlet casing portion side wall 38 and an air inlet casing portion top wall 39, wherein the air inlet casing portion side wall 38 is used for cooperating with an inner side groove side wall 57 of the base air inlet groove 23 on the air duct base 16 to form an inner side channel wall of the air inlet channel, the air inlet casing portion top wall 39 is used for forming a top channel wall of the air inlet channel, and the outer side surface of the air inlet casing portion top wall 39 is used for connecting with the air duct end cover; and the inlet housing side walls 38 and inlet housing top wall 39 form upper cover inlet slots for cooperation with the base inlet slots 23 on the air duct base 16 to form inlet air passages, wherein the upper cover exhaust slots 17 are isolated from the upper cover inlet slots. Thus, after the air duct upper cover 15 and the air duct end cover 21 are connected to form the air duct upper cover 24, the inner side wall 46 of the air duct end cover 21 will form one side wall of the upper cover air inlet groove, so that the upper cover air inlet groove 22 is formed by the air inlet shell side wall 38, the air inlet shell top wall 39 and the inner side wall 46, and the upper cover air inlet groove 22 can cooperate with the base air inlet groove 23 on the air duct base to form an air inlet passage.

In the present embodiment, as shown in fig. 2, 3, 6 and 7, the lower portion of the inlet casing side wall 38 is formed with a semicircular protrusion 41 for mating with the semicircular recess 40 on the inner slot side wall 57 of the base inlet slot 23, such that the semicircular protrusion 41 can fit within the semicircular recess 40 and be retained by the semicircular recess 40, and the upper portion of the inlet casing side wall 38 is formed with an arcuate protrusion 42, and the inlet casing top wall 39 includes an arcuate top wall portion 43 that overlies the arcuate protrusion 42. The arc-shaped top wall part 43 can be connected with the arc-shaped convex part 42 on the inner groove wall 46 of the air duct end cover in a shape matching manner, such as being welded together; the concave-convex matching structure and the hot melting connection mode enable the side wall 38 of the air inlet shell part and the base air inlet groove 23 to be matched more closely, and the air leakage situation is reduced to the maximum extent.

In addition, as shown in FIG. 2, the duct top cover may be formed in a shape of approximately L, specifically, one end of the top cover exhaust slot 17 is formed as a welding end 44, and the welding end 44 may be welded to the duct end cover 21, wherein the top cover exhaust slot 17 includes a first side wall 45, the air inlet shell side wall 38 is connected to the first side wall 45 at a position spaced apart from the welding end 44, and the slot top wall of the top cover exhaust slot 17 extends from the welding end and forms the air inlet shell top wall 39 to form a single piece.

In this embodiment, as shown in FIGS. 5-7, the air duct upper cover 15 and the air duct end cover 21 are joined together to form the air duct upper cover 24 such that the inner side slot wall 46, the inlet casing side wall 38, and the inlet casing top wall 39 together form the upper cover inlet slot 22 for cooperating with the base inlet slot 23 on the air duct base 16 to form the inlet air passage. Further, the upper cover discharge slot 17 and the wall end surface of the air inlet casing portion top wall 39 facing the welding end 44 are formed with welding ribs and/or welding grooves for welding with the inner side surface of the duct end cover. Thus, the duct end cover 21 and the duct upper cover 15 are welded together by the inside surfaces of the duct end cover with the welding ribs and/or welding grooves on the wall end surfaces of the upper cover exhaust slot 17 and the air intake casing top wall 39 facing the welding end 44 to form the duct upper cover 24, the duct upper cover 24 including the upper cover intake slot 22 having the intake air outlet 8. In this way, the air duct upper cover 24 is welded to the air duct end cover 21 to form the air duct upper cover 15, so that the possibility of air leakage between the air duct upper cover and the air duct end cover is avoided.

Meanwhile, the invention provides a clothes treatment device, which comprises the air duct upper cover, wherein an exhaust passage of the clothes treatment device for guiding hot and humid air generated by drying clothes into a washing part of the clothes treatment device comprises the upper cover exhaust groove, the clothes treatment device comprises an air inlet passage for sending air condensed by the washing part and a condensing structure arranged on the air duct upper cover into a gas heating unit, and the air heated by the gas heating unit again is used for drying the clothes.

Finally, as mentioned above, the air duct upper cover and the air duct support base provided by the invention can be applied to the clothes treatment device, so that the clothes treatment device can achieve the beneficial effects.

Therefore, a laundry treating apparatus to which the duct upper cover and the duct support base are applied will be described in detail below, specifically:

Because the first inner cavity is communicated with the second inner cavity of the second barrel body 2 through the exhaust passage, the second inner cavity of the second barrel body 2 is communicated with the gas heating unit through the air inlet passage, and the gas heating unit is communicated with the first inner cavity, in this way, hot air heated by the gas heating unit enters the first inner cavity to dry wet clothes, wet hot air generated by drying the wet clothes enters the second barrel body through the exhaust passage, after the wet hot air is condensed through the inner surface of the second barrel body or the washing drum (when the washing drum is arranged in the second barrel body), the wet hot air enters the gas heating unit through the air inlet passage to be reheated and then enters the first inner cavity to dry the clothes, thereby realizing the circulating flow of the air, avoiding the direct discharge of the wet hot air, avoiding the wet heat of the indoor air environment, and improving the indoor comfort to a certain degree. In addition, the overall quality and user experience of the clothes treatment device are remarkably improved.

Of course, it should be understood herein that the present invention provides the laundry treating apparatus, wherein the first drum 1 may be used as a drying tub, or may be used as a washing tub, and the second drum 2 may be used as a washing tub; in addition, the first cylinder 1 can be directly used as a drying tub or a washing tub, or the first cylinder 1 can be used as a drying outer tub or a washing outer tub, and a drying drum or a washing drum is arranged in the first cylinder; the second tub 2 may be directly used as a washing tub, or the second tub 2 may be used as a washing tub, and a washing drum is further provided therein.

For example, in order to improve the washing effect of the clothes and improve the condensation surface and condensation effect of the hot and humid air in the second cylinder 2, preferably, as shown in fig. 1, a washing drum 3 is disposed in the second inner cavity of the second cylinder 2, so that the hot and humid air, after entering the second inner cavity, will contact the inner circumferential surface of the second cylinder 2 and the inner and outer circumferential surfaces of the washing drum 3 and be condensed by the second cylinder 2 and the washing drum 3, which increases the condensation surface and improves the condensation effect, and water molecules in the hot and humid air are more easily condensed, and at the same time, when the washing drum 3 rotates, the hot and humid air is more easily driven to collide with the inner circumferential surface of the second cylinder 2 and the inner and outer circumferential surfaces of the washing drum 3 for condensation, and at the same time, the air is more easily driven to flow into the air inlet passage; and/or, in the height direction of the laundry treating apparatus, the first tub 1 is disposed above and the second tub 2 is disposed below, as in the structure shown in fig. 1, such that the first and second tubs 1 and 2 are arranged up and down and disposed within the casing of the laundry treating apparatus, thereby forming a dual tub washing and drying machine.

Of course, alternatively, the first drum 1 and the second drum 2 may be arranged left and right and provided within the casing of the laundry treating apparatus; alternatively, the first cylinder 1 and the second cylinder 2 may be provided in separate devices and may be communicated with the intake passage through the exhaust passage.

In addition, regardless of whether the first cylinder 1 and the second cylinder 2 are arranged up and down or left and right, further, the laundry treating apparatus includes an air duct support 4, the first cylinder 1 is disposed on the air duct support 4, and in the structure shown in fig. 1, the first cylinder 1 and the second cylinder 2 are arranged up and down, and the second cylinder 2 is disposed below the air duct support 4, wherein the air duct support 4 includes an isolated exhaust passage and an intake passage, the exhaust passage forms a part of an exhaust passage, the intake passage forms a part of an intake passage, wherein an exhaust inlet 5 at one end of the exhaust passage communicates with a first inner cavity in the first cylinder 1, and an exhaust outlet 6 at the other end of the exhaust passage communicates with a second inner cavity of the second cylinder 2; and a gas inlet 7 at one end of the gas inlet channel is communicated with the second inner cavity of the second cylinder 2, and a gas outlet 8 at the other end of the gas inlet channel is communicated with the gas heating unit.

Thus, the first cylinder 1 can be supported and positioned through the air duct supporting seat 4. For example, the existing base of the clothes dryer can be utilized, and the air inlet and the air outlet of the clothes dryer are both arranged on the base to form the air duct supporting seat 4, so that the first cylinder 1 of the clothes dryer is prevented from being provided with other holes.

Further, in order to enhance the condensation effect of the hot and humid air, the exhaust passage is provided with a cooling structure for condensing the hot and humid air flowing in the exhaust passage. For example, in one embodiment, a cooling structure is provided on a channel wall of the exhaust channel for cooling the gas flowing through the exhaust channel. In this way, the hot humid air will be condensed by the cooling structure while flowing through the exhaust passage, thereby reducing the moisture content of the hot humid air entering the second cavity of the second cylinder 2.

In some embodiments of the present invention, the cooling structure is a plurality of spaced condensation sheets disposed in the exhaust passage, such as the exhaust channel, the plurality of condensation sheets form a bent passage, and hot and humid air passing through the bent passage is condensed by the plurality of condensation sheets to reduce the moisture content.

Preferably, in the present embodiment, as shown in fig. 2, the cooling structure includes the cooling pipe 9, and a portion of the cooling pipe 9 is located in the exhaust passage, so that the hot and humid air flowing in the exhaust passage will contact the portion of the cooling pipe 9 located in the exhaust passage and be condensed.

Of course, the number of the cooling pipes 9 may be one, or a plurality of such as 3 or 4, or other more. And a plurality of cooling tubes 9 may be connected to a plurality of water outlet ends of the cooling joint 36.

Of course, the cooling pipe 9 may be directly inserted into the exhaust passage, or, preferably, in the present embodiment, as shown in fig. 2, a slit is formed on the passage top wall of the exhaust passage, and the cooling pipe 9 is disposed in the slit along the extending direction of the slit, that is, the axial direction of the cooling pipe 9 is the same as the extending direction of the slit, wherein the width of the slit is smaller than the diameter of the cooling pipe 9, so that a part of the pipe wall of the cooling pipe 9 disposed in the slit is located in the exhaust passage, and thus, the size of the pipe wall opening can be reduced, and the possibility of leakage can be reduced; while ensuring that the moist hot air flowing in the exhaust passage contacts a portion of the wall of the cooling pipe 9 in the exhaust passage and is condensed.

Further, in order to further enhance the condensation effect of the moist hot air, it is preferable that a spray hole is formed on a portion of the cooling pipe 9 located in the exhaust passage, for example, a pipe section of the cooling pipe 9 inserted into the exhaust passage, or a spray hole is formed on a portion of a pipe wall of the cooling pipe 9 located in the exhaust passage, at which time, water in the cooling pipe 9 is sprayed in a mist or jet form through the spray hole, so as to cool the moist hot air flowing in the exhaust passage.
