The laundry treating apparatus may be a washing machine, a washing and drying all-in-one machine, a dryer, etc. with a drying system. The inner tub 10 is a tub for containing laundry, and is disposed in the casing. The washing machine can be a roller washing machine with a drying system, and can also be a pulsator washing machine with a drying system. The top of the drum washing machine is provided with a flat platform which can be used as a working platform for ironing clothes. The drying system can be a heat pump type drying system, and can also be other drying systems.
The following is an example of a washing machine:
according to the scheme, the ironing system is arranged on the basis of the drying system of the existing washing machine, the ironing system and partial devices and pipelines of the drying system are shared, hot air in the drying system or hot air with hot steam can be led out to the ironing pipeline 30 only by simply arranging the ironing pipeline 30, and clothes are ironed outside the washing machine. So, not only can make full use of drying system as ironing system's heat energy source, can also reuse the hot-blast that has steam, reach the purpose of saving space and reduce cost, promote user experience.
The ironing function of this scheme both can realize when washing machine operation stoving procedure, also can move the procedure of ironing alone, realize the function of ironing. When clothes need to be dried in the inner tub 10 of the washing machine and the drying system is used, the ironing pipeline 30 can be opened at the same time, and drying air or hot air with steam in the drying air duct 20 enters the ironing pipeline 30, so that the ironing function is realized. When there is no clothes in the inner tub 10 of the washing machine, the drying air may enter the ironing duct 30 to perform an ironing function by operating some or all of the devices in the drying system.
Further, the drying air duct 20 is respectively communicated with the air inlet 11 and the air outlet 12 of the inner tub 10, a condensing device 21 and a heating device 22 are arranged in the drying air duct 20, the ironing pipeline 30 is communicated with the drying air duct 20 between the heating device 22 and the air inlet 11, and/or the drying air duct 20 between the condensing device 21 and the air outlet 12, and/or the inner tub 10, and different installation positions are adopted, so that the ironing function can be realized by using a drying system.
Furthermore, the drying system further comprises a fan 23 for driving drying air to circulate, the ironing system comprises an ironing nozzle 31 arranged at the end part of the ironing pipeline 30, and hot air and/or hot air with steam in the drying system enters the ironing nozzle 31 through the ironing pipeline 30 for ironing.
The specific scheme is as follows:

Example two
The present embodiment provides a control method of a clothes treatment apparatus as described in the first embodiment, the clothes treatment apparatus of the present embodiment has a drying system and an ironing system, and the control method includes:
the clothes processing device is provided with an ironing program, and the ironing temperature is adjusted by controlling the rotating speed of the fan and the on/off of the heating device when the washing machine executes the ironing program.
In this embodiment, the fan is the frequency conversion fan, can change the rotational speed. When the ironing program is executed, the ironing temperature is controlled by the washing machine through opening and closing of the variable frequency fan and the heating device in the drying system, so that the rapid heating and cooling can be realized, the functions of the washing machine are increased, and the user experience is improved.
Specific control methods include, but are not limited to, the following:
in the scheme 1, the ironing program at least comprises a first stage and a second stage which are sequentially executed, wherein the rotating speed of a fan in the first stage is V1, the rotating speed of the fan in the second stage is V2, and V1 is greater than V2.
Preferably, the fan rotating speed V1 in the first stage is a preset maximum rotating speed of the fan.
The first stage is the intensification stage, and the fan uses great rotational speed operation, can reach temperature balance fast, and the second stage is steady ironing stage to the V2 operation that is less than V1 can reduce the fan loss, guarantees the effect of ironing.
In a scheme 2, as shown in fig. 3, the ironing program includes a first stage, a second stage and a third stage, which are sequentially executed, wherein the rotating speed of the blower in the first stage is V1, the rotating speed of the blower in the second stage is V2, the rotating speed of the blower in the third stage is V3, and V1 is greater than V2, and V3 is greater than V2.
Preferably, the fan speed V3 in the third stage is equal to the fan speed V1 in the first stage.
More specifically, the method comprises the following steps:
(1) After the washing machine is started, executing an ironing program, firstly executing a first stage, controlling a fan to start, and controlling a heating device to start after the rotating speed of the fan reaches V1; and the rotating speed V1 of the fan in the first stage is the preset maximum rotating speed of the fan. The arrangement can maximally shorten the time for the washing machine to enter the temperature balance, and shorten the time of the whole ironing process.
(2) Judging whether the temperature of an air outlet of the drying air duct reaches a first preset temperature T or not, if so, entering a second stage, and controlling the fan to operate at V2; if not, controlling the fan to continuously operate at V1.
In this scheme, specific first preset temperature can be set as required. The second stage is a stable ironing stage, and the ironing machine operates at a V2 lower than the V1, so that the loss of the fan can be reduced, and the ironing effect is ensured.
(3) In the second stage, the fan operates at V2, and if the clothes processing device receives an instruction of stopping ironing, the third stage is entered, and the fan is controlled to operate at V3; otherwise, controlling the fan to continuously operate at V2.
(4) And when the third stage is executed, controlling the heating device to be closed, and controlling the fan to operate at V3, wherein V3 is the preset maximum rotating speed of the fan. In the third stage, the clothes processing device controls the fan to operate for a certain time m in a V3 mode, or controls the fan to be closed after the temperature of the air outlet of the drying air channel decreases to a certain value n in the V3 mode, and the ironing program is finished.
The third stage is a cooling stage, the rotating speed of the fan is increased in the cooling stage, and the fan runs at the maximum wind speed again, so that the cooling time can be greatly shortened.
In the scheme, the ironing program is divided into three stages, the first stage is carried out at the maximum rotating speed to reach the set ironing temperature, and the stage is carried out at the maximum rotating speed, so that the time for the ironing system of the washing machine to enter temperature balance can be shortened. And in the second stage, the ironing machine runs at a rotating speed V2 lower than the highest speed V1, so that the loss of the fan is reduced. When the control unit receives the ironing stop command of the user, the control unit enters a third stage and operates at the highest rotating speed V3 again (in the moment, V3 is equal to V1), and the cooling time is shortened. Through the three stage, change drying blower rotational speed, carry out the temperature regulation of flatiron fast, can make full use of washing machine's own drying system as the power source of ironing, promote user experience effect greatly.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
