Benefits of technology

The present invention is a washing and drying integrated machine with a single heating device or set of heating devices that can operate independently. The machine has separate drying and washing drums that can be heated independently through the same heating device or set of heating devices. This allows for separate supply of hot wind to the drying and washing drums, improving energy utilization. The reused hot wind from the drying drum is used to provide heat to the washing drum, improving the reutilization rate of energy. The machine also has a heating device group with different powers that can be combined to form different heating power combinations based on the quantities and water content of the clothes inside the drying and washing drums, improving both drying and washing efficiency. The control method ensures that the maximum heating efficiency is not exceeded, avoiding failure of the machine caused by over-sized 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.

embodiment 1

[0034]As shown in FIG. 1, a washing and drying integrated machine in the present disclosure includes 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 can operate independently. And the washing and drying integrated machine further includes a heating device, wherein a same heating device or a same set of heating devices is respectively connected with a drying drum in the drying drum assembly and a washing drum in the washing drum assembly via two ventilating ducts. The heating devices can provide hot wind to the drying drum and the washing drum separately or simultaneously.

[0035]In the present embodiment, the heating device includes a heater and a fan. The heater includes a case and a heater strip arranged inside the case. The case of the heater is respectively connected with the drying drum and the washing drum via two ventilating ducts, and the case of the heate...

embodiment 2

[0042]As shown in FIG. 2, the present embodiment differs from embodiment 1 as follows: the ventilating duct which connects the heating device and the washing drum includes two branch ventilating ducts. Wherein a wind inlet of one branch ventilating duct is arranged below the water surface of the washing drum, so as to heat water in the washing drum, meanwhile, the blowing of air flow can be utilized to shake and loosen clothes. A wind inlet of another branch ventilating duct is arranged above the water surface of the washing drum, so as to heat the air inside the washing drum.

[0043]Valves are arranged on the two branch ventilating ducts. Through controlling the opening and closing of the valves, the heating device can separately or simultaneously provide hot wind to the water inside the washing drum and to the air inside the washing drum, so as to improve washing and decontamination effects.

embodiment 3

[0044]As shown in FIG. 3, the present embodiment differs from embodiment 2 as follows: a wind outlet of the washing drum is connected with a wind-exhausting duct. And the wind-exhausting includes two branch wind-exhausting ducts, wherein one branch wind-exhausting duct is connected with the outside, or is connected to the heating device after being connected to a condenser so as to form recirculating air. Another branch wind-exhausting duct is connected to the washing drum, and this branch wind-exhausting duct is respectively connected with two wind inlets of the washing drum. Wherein one wind inlet is arranged above the water surface inside the washing drum, and the other wind inlet is arranged below the water surface inside the washing drum. Through the opening and closing of two valves (not shown in the figure) arranged at the two wind inlets, hot wind can be separately or simultaneously provided to the water in the washing drum and to the air in the washing drum. In the present ...

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...
