It is noted that the water box assembly 140 can also have other structures commonly used in the art, which are not limited herein.

[0054] As shown in FIG. 4 and FIG. 5, the drying assembly 131 includes a two- device mounting box 1311 and an evaporator 13121 and a condenser 13131 arranged in the two-device mounting box 1311, and the side of the two-device mounting box 1311 is open to form an air inlet of the drying assembly 131; the top of the air outlet of the filter air duct 1321 is lower than the top of the air inlet of the drying assembly 131; the first end and the second end of the air guide channel 133 are respectively communicated with the air outlet of the filter air duct 1321 and the air inlet of the drying assembly 131, and the top wall of the air guide channel 133 is configured to be adapted to the shape of the water box assembly 140 to form the avoiding space 1331. It can be understood that the drying assembly 131 can further include a fan, a throttling device, a compressor, a sealing member, a damping member, etc.

[0055] The other side of the two-device mounting box 1311 opposite to the air inlet of the drying assembly 131 is provided with an air outlet of the drying assembly 131, and the air outlet of the drying assembly 131 is connected with a fan volute 134 in which a fan is arranged, and a compressor is arranged at the rear side of the fan volute 134.

[0056] Optionally, when the bottom and the side of the water box assembly 140 facing the lint filter assembly 132 and the air guide channel 133 are provided with a slope, correspondingly, the top wall of the air guide channel 133 is configured to be a slope structure adapted to the slope. When the bottom and the side of the water box assembly 140 facing the lint filter assembly 132 and the air guide channel 133 are provided with a convex circular arc surface, correspondingly, the top wall of the air guide channel 133 is configured to be a concave circular arc surface structure adapted to the slope.

It should be noted that the positions and structures of the water box assembly 140, the lint filter assembly 132 and the air guide channel 133 should be considered simultaneously to reasonably arrange the components in the machine shell 110 of the clothes treatment device 100.

[0057] In some embodiments, the drum assembly 120 includes an outer drum and an inner drum rotatably arranged in the outer drum, a sealing window gasket is arranged between the outer drum and the inner drum, and a water inlet is arranged on the side wall of the outer drum; the box body of the water box assembly 140 is connected with a water inlet pipe 141 communicated with the water inlet; the air guide channel 133 is provided with a mounting opening through which the water inlet pipe 141 passes.

[0058] Specifically, the water inlet is generally arranged on the side wall of the outer drum near the front end, and since the lint filter assembly 132 is arranged below the water box assembly 140, the installation space of the water inlet pipe 141 is occupied. Therefore, in order not to affect the installation of the water inlet pipe 141, the installation opening for the water inlet pipe 141 to pass through is arranged on the air guide channel 133. In this way, the water box assembly 140 will not affect the water inlet to the outer drum and the sealing window gasket.

[0059] The drying air circulation process of the laundry treating apparatus 100 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0060] The wet air outlet is arranged on the outer drum and connected to the air inlet of the filter air duct 1321 through the drying bellows 121. The dry air inlet is arranged on the sealing window gasket and connected to the air outlet of the fan volute 134 through the drying air duct 122.

[0061] The wet air with a low temperature in the outer drum enters the filter air duct 1321 through the wet air outlet, the drying bellows 121, and the air inlet of the filter air duct 1321. The wet air in which lint is filtered out by the filter screen in the filter air duct 1321 enters the two-piece installation box 1311 through the air outlet of the filter air duct 1321, the air guide channel 133, and the air inlet of the drying assembly 131. The wet air is converted into dry air with a high temperature after passing through the evaporator 13121 and the condenser 13131 in the two-piece installation box 1311. The dry air in the two-piece installation box 1311 is sucked into the fan volute 134 through the air outlet of the drying assembly 131 by the fan, and then blown into the inner drum through the drying air duct 122 by the fan blade to dry the wet laundry in the inner drum.

[0062] Optionally, in order to improve the appearance of the apparatus, the filter air duct 1321 can be configured in a cuboid structure, and the rear end of the filter air duct 1321 is configured as the air inlet of the filter air duct 1321. In the front-rear direction of the laundry treating apparatus 100, the wet air outlet and the air inlet of the filter air duct 1321 are not centered, in other words, the horizontal section of the drying bellows 121 is arranged obliquely to connect the wet air outlet and the air inlet of the filter air duct 1321. In this way, the wet air entering the filter air duct 1321 is blocked by the other side wall opposite to the air outlet of the filter air duct 1321 to return to the air outlet of the filter air duct 1321, which improves the air volume and air speed entering the two-piece installation box 1311, and is beneficial to improve the drying air utilization rate and the laundry drying performance.

[0063] The internal structures of the lint filter device, the air guide channel 133, and the drying assembly 131 according to an embodiment of the present application will be described below with reference to FIGS. 4 to 6.

[0064] As shown in FIG. 4 and FIG. 5, the top wall of the air guide channel 133 is connected with the top wall of the filter air duct 1321, and the bottom wall of the air guide channel 133 is connected with the side wall and / or bottom wall of the filter air duct 1321; since the first air outlet 1322 is located on the side wall, air can be introduced to the middle-lower part of the air inlet of the drying assembly 131, and since the second air outlet 1323 is located on the top wall, air can be introduced to the middle-upper part of the air inlet of the drying assembly 131.

[0065] Optionally, the first air outlet 1322 and the second air outlet 1323 are communicated, in other words, the cross section of the air outlet of the filter air duct 1321 is in the shape of “┓”, and correspondingly, the cross section of the filter screen is also in the shape of “┓”.

[0066] In some embodiments, the outer edge of the filter screen is embedded in a pull frame, the pull frame is pullably connected with the side wall of the filter air duct 1321, and the front side of the pull frame is provided with an end plate capable of blocking the front end opening of the filter air duct 1321. In use, the pull frame is inserted into the filter air duct 1321 so that the filter screen is located between the air outlet of the filter air duct 1321 and the air inlet of the air guide channel 133; in cleaning, the pull frame is pulled out.

[0067] In order to maintain the overall appearance of the clothes treatment apparatus 100, the end plate is arranged flush with the front plate of the drawer of the water box assembly 140.

[0069] Referring again to the drawings, the two-device mounting box 1311 is provided with an evaporator mounting area 1312 and a condenser mounting area 1313 which are communicated with each other; wherein the top wall of the evaporator mounting area 1312 is provided with a spraying device 1315, the bottom wall of the evaporator mounting area 1312 is lower than the bottom wall of the air guide channel 133 and the bottom wall of the condenser mounting area 1313 to form a water collecting groove 13154, and the bottom wall of the evaporator mounting area 1312 is provided with a drain hole.

[0070] In the above scheme, the spraying device 1315 is arranged on the top of the evaporator installation area 1312, which can remove the lint attached to the surface of the evaporator 13121 and the odor in the drying air flow during the drying process by spraying water, and can accelerate the condensation of the wet and hot air on the surface of the evaporator 13121, accelerate the dehumidification of the wet and hot air, and improve the drying efficiency of the heat pump clothes treatment equipment 100. Moreover, the water collecting groove 13154 is formed at the bottom of the evaporator installation area 1312, which can collect the spraying water and prevent the spraying water from flowing to the air guide channel 133 and the condenser installation area 1313 and then entering the outer drum to contaminate the cleaned clothes.

[0071] In some embodiments, as shown in FIG. 5, the spraying device 1315 includes a spraying plate 13151 provided with spraying holes (not shown) and a water inlet connector 13152; wherein the top wall of the evaporator installation area 1312 is higher at the part corresponding to the windward surface of the evaporator 13121 than at other parts of the top wall of the evaporator installation area 1312 to form a spraying groove 13153; the spraying plate 13151 is connected with the spraying groove 13153 to form a spraying channel, and the water inlet connector 13152 communicates with the spraying channel.

[0072] In the above scheme, the spraying device 1315 is integrated on the two-device installation box 1311, which is beneficial to realize the modularization of parts, improve the production efficiency, reduce the cost, and facilitate the after-sales and maintenance.

[0073] It should be noted that the spraying plate 13151 and the spraying groove 13153 can be sealingly connected by clamping, screw connection, and cooperation with sealing pads and the like to prevent water leakage from affecting the spraying effect.

[0074] In some embodiments, the spraying plate 13151 includes a water storage part 131511 and a spraying part 131512 which are stepped up along the drying air flow direction; wherein the water inlet connector 13152 is arranged on the top wall of the evaporator installation area 1312 and corresponds to the water storage part 131511, and the spraying holes are arranged on the spraying part 131512.

[0075] In the above scheme, by arranging the spraying plate 13151 for cooling and removing lint of the evaporator 13121 as the water storage part 131511 and the spraying part 131512 which are stepped up along the transverse direction of the two-device installation box 1311, the water flow can enter the spraying part 131512 to spray on the evaporator 13121 through the spraying holes only after reaching a certain height in the water storage part 131511, which prevents the spraying holes far away from the water inlet connector 13152 from not being able to spray water, improves the uniformity of the spraying water flow, and optimizes the cooling and lint removal effect.

[0076] In some embodiments, the outer side of the top wall and / or the side wall of the two-device mounting box 1311 is provided with a back-to-back reinforcing rib. The spray groove 13153 formed by the upward protrusion of the top wall of the two-device mounting box 1311 can effectively utilize the remaining space formed by the back-to-back reinforcing rib on the top wall of the two-device mounting box 1311, reduce the internal space occupied by the spraying device 1315 in the two-device mounting box 1311, and will not disturb the flow of the drying air in the two-device mounting box 1311.

[0077] In addition, the top outer side of the water box assembly 140 is flush with the top outer side of the two-device mounting box 1311, which makes the position cooperation of each component more reasonable.

[0078] Again referring to FIG. 1, in some embodiments, the two-device mounting box 1311 is further provided with a supplementary heating device mounting area 1314, which is arranged on the side of the condenser mounting area 1313 away from the evaporator mounting area 1312. It should be noted that the supplementary heating device mounting area 1314 is used to mount a supplementary heating device, for example, a PTC electric heating pipe.

[0079] In the above scheme, the supplementary heating device mounting area 1314 is integrated into the two-device mounting box 1311, which further improves the componentization and modularization of the drying device 130 of the clothes treatment equipment 100 and improves the production efficiency.

[0080] In addition, the supplementary heating device mounting area 1314 is arranged on the side close to the fan volute 134, which can also reduce the lint attached to the supplementary heating device 13141 and improve the drying efficiency.
