Washing and drying integrated machine and control method

Abstract

A washing and drying integrated machine comprises a housing; a drying drum assembly configured to dry clothes and a washing drum assembly configured to wash clothes, which are respectively arranged inside the housing and operate independently. The washing and drying integrated machine further comprises a heating device, wherein the heating device is respectively connected with a drying drum in the drying drum assembly and a washing drum in the washing drum assembly via ventilating ducts. The same heating device provides hot wind to the inside of the drying drum and the inside of the washing drum. Opening or closing of valves on the ventilating ducts between the heating device and the drying drum as well as the washing drum, provide separate or simultaneous supply of heat to the drying drum and the washing drum, thereby realizing multiple purposes of the heating device.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a washing and drying integrated machine, and belongs to the field of washing and drying integrated machines.BACKGROUND ART[0002]In the existing washing and drying integrated machine, a dryer requires hot wind to heat its internal clothes, so as to evaporate water to achieve the purpose of drying. However, a heating device which supplies hot wind to the dryer has a single function, and can only heat the inside of the dryer. The heating device in the washing machine provides hot wind to the washing machine, and the discharged drying hot wind in the dryer is wasted.[0003]In addition, in the existing washing and drying integrated machine, a dryer requires heat to heat its internal clothes, so as to evaporate water to achieve the purpose of drying. However, the quantity and water content of clothes inside the dryer are different, therefore, a washing and drying integrated machine which can adjust power of the heating devices is requi...

AI Technical Summary

Benefits of technology

[0027]A washing and drying integrated machine in the present disclosure includes a housing; and a drying drum assembly configured to dry clothes and a washing drum assembly configured to wash clothes, which are respectively arranged inside the housing and operate independently. And the washing and drying integrated machine further includes a heating device group. The heating device group includes two or more heating devices, and the heating devices in the heating device group are combined to be opened or closed to form a heating power combination with different powers. Since the combination of heating devices is realized, when the quantity and water content of clothes inside the drying drum and inside the washing drum are different, the power of the heating device can be changed by adjusting the combination quantity of the heating devices, thereby improving drying efficiency and improving clothes washing efficiency. In the present disclosure, reutilization of the heat used for drying clothes is realized, such that the heat of damp and hot air inside the drying drum can provide heat to the washing drum, thereby improving reutilization rate of energy. As to a control method of a washing and drying integrated machine in the present disclosure, multiple heating device groups are arranged inside the washing and drying integrated machine, and the multiple heating device groups can be combined to be opened or closed based on of a heating power set by a system and a real-time heating power, so as to form a heating power combination with different powers. The maximum heating efficiency is realized on the basis of not exceeding a maximum heating power allowed by the washing and drying integrated machine system, thereby providing heat to the drying drum and the washing drum. Whether or not the sum of the actual power of the heating device which is opened and a rated power of a heating device to-be-opened exceeds a preset maximum heating power allowed by the washing and drying integrated machine is judged, so as to determine whether or not the heating device to-be-opened is allowed to open, thereby avoiding failure of the washing and drying integrated machine caused by an overlarge actual power.

Problems solved by technology

However, a heating device which supplies hot wind to the dryer has a single function, and can only heat the inside of the dryer.

The heating device in the washing machine provides hot wind to the washing machine, and the discharged drying hot wind in the dryer is wasted.

Meanwhile, the discharged drying heat in the dryer is wasted.
