Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In the related art, there are two heating modes, namely, an electric heating mode and a heat pump mode, in general, a clothes dryer. Among them, the electric heating type clothes dryer heats ambient air through resistance heat release, and the heat pump type clothes dryer heats air mainly through refrigerant heat release. The fan blows hot air into the drum, so that the temperature in the washing machine is increased, and the dried hot air flows through the surface of clothes, so that the clothes can be heated, moisture evaporated from wet clothes is taken away, and the clothes are quickly dried. However, in the drying process of the clothes dryer with the two heating modes, the temperature in the barrel is unevenly distributed, so that uneven heating of clothes in the drying process is easily caused, and the drying effect is affected. Therefore, electromagnetic heating type clothes dryers appear on the market, and the electromagnetic induction principle is adopted to heat the roller of the clothes dryer, so that air in the roller is heated. And then the air blower is matched to realize the circulation of the air flow in the barrel. Compared with electric heating and heat pump type clothes dryers, the electromagnetic heating type clothes dryer can enable temperature inside the roller to be distributed evenly, and drying effect is improved. In addition, the clothes are always in the environment with uniform heating in the drying process, so that the problems of deformation and the like caused by nonuniform heating of the clothes can be solved.

An embodiment of the present application provides a drying apparatus, please refer to fig. 1, and fig. 1 is a schematic structural diagram of the drying apparatus provided in the embodiment of the present application. The drying apparatus 100 may be a dryer or a clothes drying and washing integrated machine having a clothes drying function. The clothes drying washing machine can be a drum 2 washing machine, a parallel bar washing machine or a full-automatic pulsator washing machine. The drying apparatus 100 may be used for drying home textiles such as laundry, sheets, carpets, etc., and may also be used for drying other items other than laundry, without limitation.

The washing machine comprises a box body 1, a roller 2, an electromagnetic module 7, a fan, an air duct assembly and a condenser. The drum 2 is rotatably arranged inside the cabinet 1, and an electromagnetic module 7 is used for heating the drum 2. The fan is connected with the box 1, is provided with air intake and air outlet on the cylinder 2, and the wind channel subassembly intercommunication the air intake the air outlet, condenser and the fan, so that the inside air current circulation of cylinder 2. The condenser is mounted on the cabinet 1 for removing moisture carried in the air flow. In use, the drum 2 holds articles to be dried, and the electromagnetic module 7 heats the drum 2, so that moisture in the articles in the drum 2 is evaporated. The evaporated moisture flows out of the drum 2 from the air outlet by the fan. Subsequently, the carrier's large amount of moisture air exits the drum 2 from the air outlet of the drum 2, flows through the air duct assembly and into the condenser. The moisture in the air flow is condensed into water drops in the condenser, and falls into the drain box to be discharged outside the drying apparatus 100. The "dehumidified" air flow enters the drum 2 again, carrying away the water vapor evaporated from the articles, and then enters the condenser again. The air flow circulates in the drying apparatus 100 in such a way that the drying of the articles is completed.

The material of cylinder 2 includes the metal, and electromagnetic module 7 sets up inside the box 1, electromagnetic module 7 can produce alternating magnetic field, in order to pass through alternating magnetic field heats cylinder 2. It is understood that the metal material may generate induced electromotive force within the metal when subjected to a varying magnetic field or when moved in a non-uniform magnetic field. Under the action of induced electromotive force, the metal generates current. Such current flows along a closed circuit within the metal, and is therefore referred to as eddy current, simply eddy current. When the eddy current is hindered by the resistance of the material of the drum 2, the eddy current effect releases a great amount of heat energy, so that the temperature of the drum 2 is increased, and further, the drying of the articles in the drum 2 is realized. In this embodiment, the electromagnetic module 7 may generate an alternating magnetic field, and the material of the drum 2 includes metal, so when the drum 2 is in the alternating magnetic field, the drum 2 will generate heat under the eddy effect, thereby heating the articles in the drum 2, and evaporating the moisture in the articles. It will be appreciated that the temperature of the drum 2 varies with the parameters of the alternating magnetic field and the intensity of the thermal effect of the eddy currents.

Under the action of the current, the surrounding space of the energized wire generates a magnetic field. The magnitude, direction and frequency of the magnetic field are related to the current in the wire. The larger the current flowing in the wire, the stronger the magnetic field generated. The faster the frequency of the change in current in the wire, the faster the frequency of the change in magnetic field around the wire. In this embodiment, the electromagnetic module 7 generates the alternating magnetic field by using the electromagnetic generating magnetic principle, the electromagnetic module 7 has a plurality of working parameters, and the working parameters of the electromagnetic module 7 are different, so that the parameters of the alternating magnetic field generated by the electromagnetic module 7 are different. The operating parameter includes at least one of an operating frequency and a power. In general, the power source connected to the electromagnetic module 7 is an alternating current, and the higher the frequency of the alternating current of the electromagnetic module 7, the higher the frequency of the alternating magnetic field generated by the electromagnetic module 7, that is, the faster the change speed of the magnetic field, the higher the intensity of the eddy current in the drum 2, and the higher the generated heat. The higher the power of the electromagnetic module 7 during operation, i.e. the higher the intensity of the operating current, the higher the intensity of the magnetic field generated, the higher the intensity of the eddy currents in the drum 2, and the more heat generated for a longer time. Therefore, referring to fig. 2, fig. 2 is a schematic connection diagram of a control module and an electromagnetic module of the drying apparatus according to an embodiment of the present application. The drying device 100 further comprises a control module 4, the control module 4 is electrically connected with the electromagnetic module 7, and the control module 4 is used for controlling the working parameters of the electromagnetic module 7 to adjust the working parameters of the electromagnetic module 7, so that the temperature of the drum 2 can be adjusted, and the drying temperature of the articles is controlled.

The user may select different drying temperatures according to different articles, thereby generating input information which the control module 4 is able to receive. Alternatively, the user may connect the intelligent terminal with the drying apparatus 100, and send control information to the control module 4 through the intelligent terminal, thereby controlling the operation parameters of the electromagnetic module 7, and finally controlling the drying temperature of the drum 2.

The drum 2 is subjected to an alternating magnetic field and the thermal effect of the eddy currents continues. At the same time, the drum 2 is in a relatively closed environment, the temperature of which will continuously rise under the eddy current effect, and eventually the temperature of the inner wall of the drum 2 may exceed the expected temperature. Accordingly, the drying apparatus 100 may further be provided with a temperature detection module 6 for detecting the temperature of the drum 2.
