Problems solved by technology

However, most integrated washing machines are simple stacks of washing machines with multiple functions, which consume a lot of energy. Especially for washing machines equipped with a drying function, the heat utilization rate of the drying air heated by the heating device is small, resulting in a waste of resources.
When heating the washing water, an electric heater is usually used to heat the washing water. If the washing machine is equipped with drying parts at the same time, it is also necessary to install a heating device in the air duct. In this way, multiple heating devices cause The washing machine consumes a lot of energy, takes up a lot of space, is expensive, and is not environmentally friendly

Embodiment 1

[0043] like Figure 1-2As shown, a combined washing and drying machine includes a drying system, at least one first clothes treating drum and at least one second clothes treating drum, and the drying system includes a circulation line communicating with the first clothes treating drum 300, the circulation pipeline 300 is provided with an air supply branch 310 for introducing the drying air into the second clothes processing drum, and the circulation pipeline 300 and / or the air supply branch 310 is provided with an air supply The control part 311, the air supply control part 311 controls the air supply branch 310 to conduct, and the drying air is introduced into the second laundry treatment drum. The air supply branch is used to introduce the drying air in the first clothes treatment drum into the second clothes treatment drum, so as to realize the same supply of the first clothes treatment drum and the second clothes treatment drum by the same drying system, and save the dryin...

Embodiment 2

[0060] like Figure 1-2 As shown, this embodiment is a further limitation of Embodiment 1. The combined washing and drying machine is a washing machine, and the washing machine includes two drums, a drying drum and a washing drum, and the drying drum is arranged on the upper part of the washing drum.

[0061] The circulation pipeline 300 includes a lead-out pipeline 301 that leads out the drying air that has completed heat exchange in the drying cylinder 200. The air supply branch 310 is arranged on the lead-out pipeline 301. The air outlet end communicates with the washing tub 100 , and the drying air led out from the drying tub 200 is introduced into the washing tub 100 .

[0062] Since the temperature required for heating the washing water in the washing tub 100 or heating the air / to-be-washed items in the washing tub 100 is relatively low, the cost of separately setting the heating device 330 is high. The heat-exchanged drying air is introduced into the washing tub 100. S...

Embodiment 3

[0075] like Figure 1-2 As shown, this embodiment is a further limitation of Embodiment 2. The washing tub 100 is provided with a washing water heating branch pipe 302 for introducing the drying air into the washing water in the washing tub 100 and / or for introducing the drying air into the washing water. Air heating branch pipe 303 is introduced into the air above the wash water level.

[0076]The communication port on the washing tub 100 that communicates with the washing water heating branch pipe 302 is set below the lowest liquid level in the washing tub 100, so that the drying wind can heat the washing water in the washing tub 100, accelerate the washing speed, and improve the washing effect. Creates bubbling agitation for faster washing speed and efficiency. The communication port communicating with the air heating branch pipe 303 is set above the highest liquid level in the washing tub 100 to heat the load (such as items to be washed or air) in the washing tub 100 .

Abstract

The invention belongs to the field of household appliances, and in particular relates to a combined washing and drying machine and a control method, comprising a drying system, at least one first clothes treating drum and at least one second clothes treating drum, the drying system It includes a circulation pipeline that communicates with the first laundry treatment drum, and an air supply branch is arranged on the circulation pipeline for introducing drying air into the second laundry treatment drum. The circulation pipeline and / or the air supply branch An air supply control part is provided on the road, and the air supply control part controls the conduction of the air supply branch, and guides the drying air into the second clothes processing drum. The beneficial effect of the present invention is that by setting the air supply branch, the same set of The drying system heats / dries the loads in the first clothes treatment drum and the second clothes treatment drum to save space and cost; the drying air in the first clothes treatment drum is introduced into the second clothes treatment drum to realize drying The multi-level utilization of dry air makes the utilization effect of drying air higher.

Description

technical field [0001] The invention belongs to the field of household appliances, in particular to a combined washing and drying machine and a control method. Background technique [0002] Washing machines are cleaning appliances that use electrical energy to produce mechanical action to wash clothes. According to their rated washing capacity, they are divided into two categories: household use and collective use. China stipulates that a washing machine with a washing capacity of less than 6 kg belongs to a household washing machine: a household washing machine is mainly composed of a box, a washing and dehydrating bucket (some washing and dehydrating buckets are separated), a transmission and control system, and some are also equipped with a heating device. [0003] As people's requirements for washing machines are getting higher and higher, integrated washing machines and multi-functional washing machines are more and more popular. However, most of the integrated washing...
