as shown in fig. 5, the drum 210 includes an outer cylinder 213 and an inner cylinder 214 disposed in the outer cylinder 213, a water inlet gap 215 is formed between the outer cylinder 213 and the inner cylinder 214, and the connection port 212 may be opened at a lower position of a rear end of the outer cylinder 213 and is communicated with the water inlet gap 215.
As shown in fig. 5, the washing machine further includes: a fan 310; an inlet a of the drying air duct 320 is communicated with an air outlet of the fan 310, and an outlet B is positioned at the front end of the drum 210 and is communicated with the clothes input port 211; the heating component 340, the heating component 340 is arranged in the drying air duct 320; the condenser 330, the condenser 330 includes: as shown in fig. 5 and 8, the air outlet 1 is located at the top of the condenser 330 and is communicated with the air suction inlet of the fan 310; an air inlet 2, the air inlet 2 is positioned at the bottom of the condenser 330 and is opposite to the rear end of the drum 210, and the air inlet 2 is communicated with the connecting port 212; the condensation air flue 3, the condensation air flue 3 includes main air flue 31 and crooked transition air flue 32, the upper end of the main air flue 31 communicates with air outlet 1, the underpart passes the crooked transition air flue 32 and connects with edge of the air inlet 2; the condensed water channel 4 is arranged in the condensed air channel 3; a condensed water inlet 5, the condensed water inlet 5 being provided on the condenser 330 and communicating with the condensed water channel 4.
The heating element 340 may be a heating pipe (as shown in fig. 5), a heating wire, or a condensing pipe in a refrigerant system, and is not particularly limited herein; the condensed water inlet 5 is communicated with a water inlet system 400 of the washing machine.
As shown in fig. 5, after the washing machine washes the laundry, the laundry is placed in the drum 210, then the fan 310 and the heating element 340 are turned on, the air blown from the air outlet of the fan 310 enters the drying air duct 320, and is heated by the heating element 340 to become hot air, the hot air enters the drum 210 through the laundry input port 211 to take away the moisture on the laundry, so as to dry the laundry, the hot air taking away the moisture of the laundry becomes damp hot air saturated with water vapor, the damp hot air enters the condensing air duct 3 through the connection port 212 and the air inlet 2 of the condenser 330, and exchanges heat with the water in the condensed water channel 4 to become dry air, and finally the dry air enters the fan 310 through the air outlet 1 of the condenser 330 to complete an air cycle. The wind from the fan 310 continuously circulates among the drying duct 320, the drum 210, and the condenser 330 until the laundry in the drum 210 is dried.
As shown in fig. 8, the washing machine provided in the embodiment of the present invention includes a main air duct 31 and a curved transition air duct 32, and the lower end of the main air duct 31 is connected to the edge of the air inlet 2 through the curved transition air duct 32, so that the edge of the air inlet 1 and the main air duct 31 can be smoothly transitioned by providing the curved transition air duct 32, and the excessive turning angle of the condensation air duct 3 is avoided, so that the accumulation of the lint at the corner of the air inlet 2 and the main air duct 31 can be greatly reduced, thereby ensuring the smooth air flow of the drying system, and being beneficial to ensuring the drying efficiency of the drying system.
As shown in fig. 10 to 13, the inner wall of the curved transition duct 32 includes a flow guide wall 321 disposed opposite to the air inlet 2, and the flow guide wall 321 is connected between the edge of the air inlet 2 and the main duct 31;
the shape of the drainage wall 321 is not exclusive, and for example, the drainage wall 321 may be an inclined plane. So that the hot and humid air introduced from the air inlet 2 is guided to the main duct 31 along the inclined surface. As shown in fig. 10, the drainage wall 321 may have a curved surface. So that the hot and humid air entering from the air inlet 2 can be guided to the main duct 31 along the arc surface.
When the drainage wall 321 is in an inclined plane shape, the inclination angle θ of the drainage wall 321 (i.e. the included angle between the drainage wall 321 and the horizontal plane) is an important parameter, and the inclination angle θ should not be too large or too small. If the inclination angle θ is too large, the flow guiding wall 321 is too steep, and the energy loss of the damp and hot wind entering the main air duct 31 from the air inlet 2 through the flow guiding wall 321 is large; if the inclination angle θ is too small, the flow guiding wall 321 is too gentle, and the flow guiding wall 321 occupies too much space in the curved transition duct 32, so that the ventilation area of the curved transition duct 32 is reduced, which is disadvantageous to the improvement of the ventilation efficiency of the condenser 330. Research shows that when the inclination angle of the flow guide wall 321 is in the range of 45 degrees to 60 degrees, energy loss of damp and hot air entering the main air duct 31 from the air inlet 2 through the flow guide wall 321 is small, and the occupation of the flow guide wall 321 on the space in the curved transition air duct 32 can be reduced, so that the ventilation efficiency of the condenser 330 is ensured.
In order to improve the heat exchange efficiency of the condensed water with the damp and hot air, as shown in fig. 8 and 12, the outlet of the condensed water channel 4 is located in the curved transition duct 32. Because the bent transition air duct 32 is close to the air inlet 2, the flow velocity of the damp and hot air in the bent transition air duct 32 is large, and the outlet of the condensed water channel 4 is arranged in the bent transition air duct 32, so that the water flowing out from the lower end of the condensed water channel 4 is easily blown up and scattered by the damp and hot air in the condensed air duct 3, the water is fully contacted with the damp and hot air and heat exchange is generated, the heat exchange efficiency of the water and the damp and hot air is improved, and the moisture in the damp and hot air can be more fully condensed.
In order to further improve the heat exchange efficiency between the condensed water and the moist and hot air, as shown in fig. 8 and 12, the condensed water channel 4 includes a main water channel 41, the main water channel 41 extends along the condensed air duct 3, and the upper end of the main water channel 41 is communicated with the condensed water inlet; and a branch water channel 42, a first end of the branch water channel 42 is connected with the lower end of the main water channel 41, a second end extends to the edge of the drainage wall 321 and is used for guiding the water in the condensed water channel 4 to the drainage wall 321, and the second end of the branch water channel 42 is an outlet of the condensed water channel 4. After the hot and humid air enters the curved transition air duct 32 from the air inlet 2, the hot and humid air enters the main air duct 31 along the drainage wall 321, and the wind speed is higher at the position closer to the drainage wall 321. Therefore, with the arrangement, the secondary water can flow onto the drainage wall 321 along the main water channel 41 and the branch water channel 42, and is blown up by the wet hot air with higher speed close to the drainage wall 321 and dispersed into smaller water drops, so that the water is in more sufficient contact with the wet hot air, the heat exchange efficiency of the water and the wet hot air is further improved, and the moisture in the wet hot air can be more sufficiently condensed.
Here, the arrangement of the branch water passage 42 is not exclusive, and for example, as shown in fig. 12, a first end of the branch water passage 42 may be arranged higher than a second end of the branch water passage 42; in addition, the first end of the branch water passage 42 may also be the same height as the second end of the branch water passage 42. When the first end of the branch water passage 42 may be disposed higher than the second end of the branch water passage 42, the water in the main water passage 41 may be conveniently flowed onto the drainage wall 321 by the gravity.
In the condenser 330, the structure of the condensation water channel 4 is not exclusive, for example, as shown in fig. 8 and 9, the condensation water channel 4 may be a groove provided on the inner wall of the condensation air duct 3, the groove extending along the condensation air duct 3. In addition, the condensation water channel 4 may also be a pipeline disposed on the inner wall of the condensation air duct 3, and the pipeline extends along the condensation air duct 3. Compare the pipeline, when condensate water channel 4 was the recess, condensate water channel 4 was whole for open water channel, and at the in-process that water flowed in the recess, can fully contact with the damp and hot wind in condensation wind channel 3 to can improve the water in the condensate water channel 4 and damp and hot wind's heat exchange efficiency, make the moisture in the damp and hot wind can be more abundant condensation.
In the embodiment where the condensation water channel 4 is a groove, the arrangement of the condensation water channel 4 is not exclusive, for example, as shown in fig. 9, the condensation water channel 4 may be arranged in an inclined manner with respect to the horizontal plane, that is, the inner wall of the condensation air duct 3 is arranged in an inclined manner with respect to the horizontal plane, and the condensation water channel 4 is arranged on the inner wall of the inclined condensation air duct 3. In addition, the condensate channel 4 may also be arranged vertically. Compared with the vertical arrangement, when the condensed water channel 4 is obliquely arranged, the damp and hot air in the condensed water channel 3 can blow up the water in the condensed water channel 4 more easily, so that the damp and hot air can be contacted with the damp and hot air in the condensed water channel 3 more fully, and the heat exchange efficiency of the water and the damp and hot air in the condensed water channel 4 can be further improved.
In the embodiment where the condensed water channel 4 is disposed in an inclined manner with respect to the horizontal plane, in order to further improve the heat exchange efficiency between the water and the hot and humid air in the condensed water channel 4, as shown in fig. 9, the condensed water channel 4 includes: the first arc section 43, the first arc section 43 is bent towards the outside of the condensation air duct 3, and the condensed water inlet 5 is arranged on the first arc section 43; a second arc section 44, the upper end of the second arc section 44 is connected with the lower end of the first arc section 43, and the second arc section 44 is bent towards the inner side of the condensation air duct 3. Because the first arc-shaped section 43 is bent towards the outer side of the condensation air duct 3, the inclination of the first arc-shaped section 43 relative to the horizontal plane is more gentle, and the flow velocity of water in the first arc-shaped section 43 is relatively slow, so that the water in the gentle first arc-shaped section 43 can be easily blown up by the damp and hot air in the condensation air duct 3 and is in relatively long contact with the damp and hot air, and the heat exchange efficiency is favorably improved; since the second arc section 44 is bent toward the inner side of the condensation duct 3, the second arc section 44 is steeper relative to the horizontal plane, and the flow speed of water in the second arc section 44 is relatively fast; because the second arc-shaped section 44 is arranged below the air inlet 2, the air speed of the condensation air duct 3 is relatively high, and the water with high flow speed in the second arc-shaped section 44 meets the moist hot air with high air speed, so that the moist hot air in the second arc-shaped section 44 is blown more dispersedly, the contact between the water in the second arc-shaped section 44 and the moist hot air is more sufficient, and the heat exchange efficiency is improved.
As shown in fig. 10 and 11, the inner wall of the condensation duct 3 includes: the front wall 33 and the rear wall 34 are arranged oppositely along the axial extension direction Y of the drum 210, the front wall 33 is an inner wall of the condensation air duct 3 on one side close to the drum 210, and the rear wall 34 is an inner wall of the condensation air duct 3 on one side far away from the drum 210; the two side walls 35 are disposed opposite to each other in the width direction X of the cabinet 100 (i.e., a direction perpendicular to both the height direction H of the cabinet 100 and the axial extending direction Y of the drum 210), and both the side walls 35 are disposed obliquely in the width direction X of the cabinet 100. The condensation water channel 4 can be arranged on a side wall 35, the contour of which 35 corresponds to the contour of the condensation water channel 4.
In order to prevent the temperature of the wind input into the drum 210 from being too high in the drying duct 320, as shown in fig. 5, the washing machine further includes a temperature sensor 350, and the temperature sensor 350 is disposed in the drying duct 320 and is located at a side of the heating member 340 close to the outlet of the drying duct 320. Thus, the temperature sensor 350 can detect the temperature of the air passing through the heating element 340 in the drying air duct 320, and when the temperature of the air exceeds the upper limit value of the preset temperature range, the heating element 340 stops working, so that the over-high temperature of the air can be avoided, and the overheated air can be prevented from entering the drum 210 to damage the clothes.
The washing machine in the embodiment of the present invention may be a drum 210 washing machine, or may be a multi-drum washing machine having a drum 210, specifically, as shown in fig. 2 and 3, the washing machine further includes an upper washing drum 220, the upper washing drum 220 is disposed above the drum 210, and the upper washing drum 220 is a pulsator washing drum. By arranging the upper washing drum 220 above the drum 210, the classified washing of the laundry is more convenient, for example, large laundry can be placed in the drum 210 for washing, and small laundry can be placed in the upper washing drum 220 for washing.
The upper washing tub 220 may be a pulsator type washing tub, or a drum type washing tub as shown in fig. 7, and is not particularly limited thereto.
As shown in fig. 3, the number of the upper washing tub 220 may be two, and the two upper washing tubs 220 are arranged side by side above the drum 210. In addition, the number of the upper washing tub 220 may be one. When the number of the upper washing tub 220 may be two, the number of the washing tubs selectable by the user is more, which is more convenient for the user to separately wash.
In the drying system, in order to fully utilize the space at the top of the drum 210, as shown in fig. 3, the fan 310 is disposed at the top of the drum 210 and at the rear end of the drum 210, so that the drum 210, the upper washing drum 220 and the fan 310 can be more compact, the space at the top of the drum 210 is fully utilized, and the fan 310 is prevented from occupying other spaces in the cabinet 100.
The drying air duct 320 is not provided in a unique manner, for example, the drying air duct 320 may pass through between the upper washing drum 220 and the drum 210, specifically, as shown in fig. 6, an escape space 230 is provided between the upper washing drum 220 and the drum 210, and the drying air duct 320 passes through the escape space 230. In addition, the drying duct 320 may also horizontally bypass from the side of the upper washing tub 220. Compared with the drying air duct 320 which bypasses from the side direction of the upper washing drum 220 along the horizontal direction, the drying air duct 320 passes through the avoiding space 230, so that the drying air duct 320 and the washing drum assembly are more compact, the length of the drying air duct 320 is favorably reduced, the excessive bending of the drying air duct 320 is avoided, and the air flows more smoothly in the drying air duct 320.

Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
