Unless defined otherwise, all technical terms used in the embodiments of the present utility model have the same meaning as commonly understood by one of ordinary skill in the art.

In some related technical schemes, the air door is passively controlled, when the fan is opened, the air door is blown by the air flow to be passively opened, but the resistance of the air flow can be increased by the existence of the air door, so that the efficiency of the fan is reduced, the drying performance of the washing machine is influenced, and the user experience is reduced.

In addition, in some related technical schemes, in order to reduce the wind resistance of the air door, a special motor is configured for the air door, and the motor controls the opening or closing of the air door, but this increases the cost of the washing machine, and meanwhile, the logic burden of the washing machine is increased due to the complex control logic of the motor.

Therefore, the air door assembly provided by the utility model has the advantages that the air door main body is driven by the electromagnet which is simple in structure, low in cost and convenient to assemble and control, and the wind resistance of the air door main body is reduced, so that the drying efficiency of the washing machine is improved, and the user experience is improved.

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.

In one aspect, as shown in connection with FIG. 1, there is provided a damper assembly comprising: a damper body 1 and an electromagnet 2.

The air door main body 1 is movably arranged in an air flow channel 3 of the washing machine and can rotate to open or close the air flow channel 3; the electromagnet 2 is located at one side of the damper body 1, and the electromagnet 2 is used for generating electromagnetic attraction force to enable the damper body 1 to rotate so as to open the air flow channel 3.

According to the air door assembly, the air door main body 1 is driven by the electromagnet 2, so that the air pressure consumed by the air door main body 1 can be reduced, the wind resistance of the air door main body 1 is reduced, the drying efficiency of the washing machine is improved, and the user experience is improved; in addition, the electromagnet 2 has simple structure and simple assembly and control logic, and is beneficial to reducing the production cost of the washing machine.

In some possible implementations, the electromagnet 2 includes a spiral tube and a core, the core is located in the spiral tube, when the spiral tube is energized, a magnetic field is generated in the spiral tube, the core is magnetized by the magnetic field, and the magnetized core also becomes a magnet, so that the magnetism of the solenoid is greatly enhanced due to the superposition of the two magnetic fields.

Thus, the throttle assembly of the present embodiment can control the opening or closing of the throttle body 1 by controlling the on-off of the current in the spiral tube in the electromagnet 2.

Further, the magnitude of the magnetic field generated by the electromagnet 2 can be reasonably adjusted through the magnitude of the current flowing in the spiral coil, the number of turns of the spiral coil and the magnetic coefficient of the iron core, so that a better control effect is achieved.

Alternatively, the damper main body 1 is made of a metal material that can be magnetically adsorbed, such as iron, stainless steel, or the like.

As shown in connection with fig. 1, in some embodiments, the damper assembly further includes a shaft member 4 and a metal rod 5; the throttle body 1 is rotatably connected with the top wall of the air flow channel 3 through a rotating shaft member 4.

The metal rod piece 5 and the air door main body 1 are connected on the rotating shaft piece 4 in parallel, and the position of the metal rod piece 5 corresponds to the position of the electromagnet 2; the electromagnet 2 generates electromagnetic attraction force to attract the metal rod piece 5, the metal rod piece 5 drives the rotating shaft piece 4 to rotate, and the rotating shaft piece 4 drives the air door main body 1 to rotate so as to open the air flow channel 3.

The electromagnet 2 in this embodiment corresponds to the position of the metal rod 5, and after the electromagnet 2 is electrified, the metal rod 5 can be adsorbed, and the air door main body 1 is driven to rotate through the metal rod 5 and the rotating shaft 4, so that the air flow channel 3 is opened or closed.

The metal rod piece 5 is used for replacing the air door main body 1 to receive the attraction of the electromagnet 2, on one hand, the electromagnet 2 and the metal rod piece 5 can be arranged outside the air flow channel 3 through the extending rotating shaft piece 4, occupation of the air flow channel 3 is reduced, and extra wind resistance is generated to air flow due to the concave-convex structure. On the other hand, since the damper main body 1 does not need to adopt a magnetic material, the damper main body 1 can be made of other materials with lighter weight and lower cost, and the product cost of the washing machine is further reduced.

Illustratively, the material of the damper body 1 includes, but is not limited to, polyamide (also called Nylon), polycarbonate (PC), fiberglass (FG), polyethylene (PE), polyethylether (Polyethylene), polyethylene terephthalate (Polyethylene Glycol Terephthalate, PET), polymethyl methacrylate (Polymethyl Methacrylate, PMMA), polypropylene (Polypropylene), polystyrene (PS), polyvinyl chloride (Polyvinyl Chloride, PVC), and the like. Any one or a combination of any of the above materials may be used to form the present embodiments.

In the damper assembly of the present embodiment, due to the special structure of the airflow channel 3, the electromagnet 2 cannot be disposed on the downstream side of the damper main body 1, so that the space of the airflow channel 3 is occupied, and the damper main body 1 does not have enough rotation space. Therefore, the metal rod 5 is disposed at an angle to the damper main body 1 such that the metal rod 5 protrudes toward the electromagnet 2, so that the electromagnet 2 can be disposed at the top of the air flow passage 3 and such that the downstream side of the damper main body 1 has a rotation space of 90 °.

When the damper main body 1 is rotationally attached to the top wall of the airflow channel 3 or is parallel to the airflow direction, the metal rod 5 naturally protrudes above the rotating shaft member 4, so that the height of the electromagnet 2 needs to be greater than the height of the rotating shaft member 4.

In some possible implementations, the included angle a has a value of, for example, 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, and so on.

On the other hand, as shown in connection with fig. 5, the present embodiment provides a drying apparatus including: the damper assembly of the present utility model.

In some embodiments, as shown in connection with fig. 5, the blower 6 includes a power cord 61, the power cord 61 being electrically connected to the electromagnet 2, the electromagnet 2 and the blower 6 being powered on or off simultaneously.

Thus, the control of the electromagnet 2 and the fan 6 in this embodiment are simultaneously controlled, the electromagnet 2 and the fan 6 start to work simultaneously, stop to work simultaneously, the fan 6 is electrified to generate wind pressure to push the damper main body 1 to rotate primarily, and the electromagnet 2 generates a magnetic field to attract the damper main body 1 to rotate to be opened completely.

In the drying device of this embodiment, the electromagnet 2 is controlled in linkage with the fan 6 or the heating element 7, and in the initial condition, the air door assembly is in a closed state, so as to block the air flow channel 3. When the drying device starts to work, the fan 6 is started, the electromagnet 2 is electrified to generate a magnetic field, after the air flow generated by the fan 6 pushes the air door main body 1 to the half-open position, the metal rod piece 5 is attracted by the electromagnet 2, the air door main body 1 rotates to the full-open position under the action of the adsorption force of the electromagnet 2, the air flow channel 3 is fully opened, and the power generated by the fan 6 is used for air flow conveying in percentage.
