As shown in
Specifically, the dryer 1 further includes a drying drum 11 as a first laundry treatment cylinder, and the washing machine 2 includes a washing drum 21 as a second laundry treatment device. The drying system is capable of delivering the drying airflow simultaneously or separately into the drying drum 11 and the washing drum 21.

Further, a bottom of the drying drum 11 is provided with a vent hole (not shown) that communicates with the first air inlet duct 12. A drum opening of the drying drum 11 (specifically, at the position of a door seal) is sealingly connected with the first air outlet duct 13 (the left end of the drying drum 11 in
In a possible embodiment, a front end of the drying drum 11 (the end having the drum opening) is fixed to the body of the laundry treatment apparatus through a roller, and a rear end of the drying drum 11 is fixed to the body of the laundry treatment apparatus through a rolling shaft so that the drying drum 11 is rotatable about an axis center thereof. Further, a rear plate is disposed on the body of the laundry treatment apparatus, and a through hole is disposed in the rear plate. An end of the through hole communicates with the vent hole of the drying drum 11, and the other end of the through hole communicates with the first air inlet duct 12. The front end of the drying drum 11 is provided with a through hole in the radial direction for communicating the inner cavity of the drying drum 11 with the first air outlet duct 13. For example, the first air outlet duct 13 has an annular air duct disposed around the drying drum 11, the annular air duct is sealingly connected with the drying drum 11, and the through hole at the front end of the drying drum 11 is located in the annular air duct. Of course, the technical solution of the present disclosure is not limited to this specific arrangement of air duct, and any air duct structure that is capable of delivering hot air in the drying air duct 3 into the drying drum 11 and delivering humid hot air in the drying drum 11 back to the drying air duct 3 can be applied to the technical solution of the present disclosure.

As shown in
Furthermore, although not shown in the drawings, in a preferred embodiment of the present disclosure, a filter screen is further provided in the drying air duct 3 on a side of the condenser 34 that is remote from the heater 33, and the filter screen is configured to filter floccules in the drying drum 11 and the washing drum 21 that enter the drying air duct 3 with the airflow to prevent the floccules from entering the drying air duct 3 and accumulating, especially to avoid an adverse effect on the fan 35 and further on a drying effect of the laundry treatment apparatus.
The working principle of the laundry treatment apparatus of the present disclosure will be described in detail below with reference to
As shown in
When the user uses the washing drum 21 of the washing machine 2 to dry the laundry, the first switching valve 31 and the second switching valve 32 are switched to the positions shown in
When the user uses the drying drum 11 of the dryer 1 to dry the laundry, the first switching valve 31 and the second switching valve 32 are switched from the positions shown in
In summary, in a preferred embodiment of the present disclosure, a drying system is shared by the dryer 1 and the washing machine 2, so that the washing machine 2 can directly dry the laundry after washing of the laundry is completed. As compared to the existing technologies in which the washed laundry in the washing machine is taken out and then placed in the dryer for drying, the present disclosure is more convenient, simplifies the operation of the user, and improves the user experience in use. By providing the clutch 15 between the motor 14 and the drying drum 11, the motor 14 can selectively drive the drying drum 11 to rotate or to keep stationary at the same time of driving the fan 35 to rotate. The number of motors is reduced as compared to a situation where motors are provided separately for driving the drying drum 11 and the fan 35 respectively. Further, those skilled in the art may also configure the motor 14 to selectively drive the washing drum 21 to rotate through the clutch 15 as needed, thereby omitting the motor on the washing machine 2 and further reducing the number of motors. Further, through the technical solution in which the dryer 1 and the washing machine 2 are provided as one piece, the operation of the dryer 1 and the washing machine 2 can be controlled simultaneously by one set of control panels, which simplifies the operation and improves the user experience in use.
Further, the laundry treatment apparatus of the present disclosure can dry the laundry by the dryer 1 at the same time the user is using the washing machine 2 to wash the laundry, thereby saving the washing and drying time for the user.
Moreover, in addition to the above preferred embodiments of the present disclosure, in another possible embodiment, the first air outlet duct 13, the second air outlet duct 23 and the air inlet end of the drying air duct 3 may also directly communicate with the outside so that external air directly enters the drying air duct 3 to be heated, and the heated airflow enters the dryer 1 or the washing machine 2 and then directly reaches the outside through the first air outlet duct 13 or the second air outlet duct 23. The arrangement of the condenser 34 may be omitted in this embodiment, but since the airflow from the dryer 1 or the washing machine 2 is not condensed in this embodiment, the airflow directly enters the room, the warm and humid air will bring inconvenience to the indoor personnel, and will also corrode the parts of the laundry treatment apparatus, thus reducing the service life of the laundry treatment apparatus. In this embodiment, condensers 34 may be separately disposed in the first air outlet duct 13 and the second air outlet duct 23 to prevent humid air from entering the room.
Further, although not shown in the drawings, a plurality of the second laundry treatment devices of the present disclosure may be provided, and the switching device may be appropriately adjusted so that the drying airflow generated by the drying assembly can be delivered simultaneously or separately to the second laundry treatment cylinder of each of the second laundry treatment devices through the adjusted switching device.
Further, the engagement device of the present disclosure is not limited to the one form of the clutch shown in the drawings, and it may also be any other feasible engagement device as long as connection/disconnection of power transmission between the motor and the drying drum or the washing drum can be realized. In addition, the engagement device of the present disclosure may also be configured as a multi-position engagement device such that the driving device (e.g., the motor 14) can selectively drive a plurality of second laundry treatment cylinders to rotate through the multi-position engagement device. For example, the motor 14 may also be selectively connected to the washing drum 21 through the clutch 15, and when the washing drum 21 is used to dry the laundry, the clutch 15 may be switched to a position where it is connected with the washing drum 21, thereby keeping the washing drum 21 rotating at the same time hot air is supplied. Preferably, the number of positions of the multi-position engagement device is equal to the sum of the number of the first laundry treatment devices and the number of the second laundry treatment devices, so that the driving device can selectively drive each of the laundry treatment cylinders to rotate through the multi-position engagement device. In this way, the laundry treatment apparatus of the present disclosure is capable of driving all of the laundry treatment cylinders to rotate by only one motor.
Further, those skilled in the art may select the types of the first laundry treatment device and the second laundry treatment device according to actual requirements. For example, the first laundry treatment device and the second laundry treatment device may respectively be any one of a washing machine, an integral washing and drying machine, or a drying machine.
Heretofore, the technical solutions of the present disclosure have been described in conjunction with the preferred embodiments shown in the drawings, but it is obvious to those skilled in the art that the scope of protection of the present disclosure is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principle of the present disclosure. The technical solutions after the modification or replacement will fall within the scope of protection of the present disclosure.
