Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

In the description of the embodiments of the present application, "up", "down", "orientation or positional relationship is based on the orientation or positional relationship shown in fig. 1, it is to be understood that these orientation terms are merely for convenience in describing the present application and for simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Referring to fig. 1, the laundry treating apparatus includes a washing drum 10, a supporting assembly 20, and an electromagnetic heating device 30. The washing drum 10 is rotatably supported on the supporting assembly 20, and the supporting assembly 20 supports the washing drum 10; the electromagnetic heating device 30 is fixed relative to the support assembly 20, i.e. the electromagnetic heating device 30 does not rotate with the washing drum 10. The electromagnetic heating device 30 can perform electromagnetic induction heating of the washing tub 10 when energized.

Referring to fig. 3, the heating principle of the electromagnetic heating device 30 for the washing drum 10 is as follows: the electromagnetic heating device 30 has an electromagnetic coil 31, when the electromagnetic coil 31 is energized, the alternating current of the power supply generates an alternating magnetic field around the electromagnetic coil 31, the magnetic induction line 30' in fig. 3 passes through the wall of the washing drum 10, the washing drum 10 in the alternating magnetic field generates a vortex current, and the joule effect of the vortex current causes the temperature of the washing drum 10 to rise, thereby heating the washing drum 10.

The clothes treatment equipment of the embodiment of the application heats the washing drum 10 by using the electromagnetic heating device 30, and heat conduction is carried out between the washing drum 10 and the washing water after heating, so that the washing water is heated, the conduction of the washing water can be avoided, and the heating safety of the clothes treatment equipment is improved.

The specific installation position of the electromagnetic heating device 30 is not limited as long as the washing drum 10 can be heated.

Exemplarily, in an embodiment, the position of the electromagnetic heating device 30 is not higher than the highest water level allowed in the washing drum 10 along the height direction of the laundry treatment apparatus. It should be noted that the maximum water level of the clothes treatment device design allowed in the washing drum 10, that is, the maximum water level of the clothes treatment device design in any washing mode, cannot be exceeded. Since the position of the electromagnetic heating device 30 is not higher than the highest water level allowed in the washing tub 10, that is, the main heat generating area of the washing tub 10 is in contact with or close to the washing water during the heating process, even if the washing tub 10 does not rotate during the heating process, the local temperature of the washing tub 10 can be prevented from being too high, and the safety of the laundry treatment apparatus can be further improved.

The specific material composition of the washing tub 10 according to the embodiment of the present invention is not limited as long as it can generate magnetic field induced current. For example, in some embodiments, the washing drum 10 is wound from sheet metal; in other embodiments, the washing drum 10 is not conductive, and a metal layer is plated on the inner wall of the washing drum 10; alternatively, the washing tub 10 has at least two plates, the inner plate being a metal plate.

The specific configuration of the electromagnetic heating device 30 is not limited as long as it can generate an alternating magnetic field. For example, referring to fig. 3, the electromagnetic coil 31 is wound in such a way that the magnetic lines of force 30' penetrate into a portion of the structure of the washing drum 10.

The rotation axis direction of the washing drum 10 in the embodiment of the present application is not limited, for example, the rotation axis may be a horizontal direction, in which case the laundry treatment apparatus is a drum-type laundry treatment apparatus, and the rotation axis may also be a vertical direction, in which case the laundry treatment apparatus is a pulsator-type laundry treatment apparatus. The shaft axis may also be an inclined direction between the horizontal direction and the vertical direction, for example, a pulsator type laundry treating apparatus.

It should be noted that the electromagnetic heating device 30 may be disposed at any suitable position.

Illustratively, in one embodiment, a circumferential end of the washing drum 10 is provided with a laundry input opening, and a user can input and output laundry from the laundry input opening. Referring to fig. 1, the electromagnetic heating device 30 is located at the other axial end of the washing drum 10. The relatively large installation space at the other axial end of the washing drum 10 prevents the electromagnetic heating device 30 located in the axial direction from being hit even if the washing drum 10 eccentrically rotates during rotation.

It is understood that the electromagnetic heating device 30 may be disposed at any position of the circumference of the washing drum 10.

The electromagnetic heating device 30 may be mounted on any suitable structure. For example, in one embodiment, the laundry treating apparatus includes a cabinet, the washing drum 10 is disposed in the cabinet, and the electromagnetic heating device 30 may be mounted on the cabinet.

For another example, in one embodiment, the electromagnetic heating device 30 is disposed on the support assembly 20. The support assembly 20 is located closer to the washing drum 10 to facilitate heating of the washing drum 10 by the electromagnetic heating device 30.

The specific structure of the supporting assembly 20 is not limited as long as it can rotatably support the washing drum 10.

Illustratively, in some embodiments, the supporting assembly 20 is an outer tub, the washing drum 10 is rotatably disposed in the outer tub, and the electromagnetic heating device 30 is disposed on the outer tub. It is understood that the electromagnetic heating device 30 may be disposed outside the outer tub, or may be disposed inside the outer tub, which is not limited herein. It should be noted that, in this embodiment, the washing drum 10 may be a perforated inner drum, that is, an outer drum for holding washing water; the washing drum 10 can also be a non-porous inner drum, in the process of washing clothes, washing water is contained in the washing drum 10, a drain hole is formed in the washing drum 10, and the drain hole can be selectively closed or opened, so that the problem that dirt is easily stored and dirt is easily taken due to the fact that water is contained in an outer drum can be avoided.

In some embodiments, support assembly 20 is a bracket to which electromagnetic heating apparatus 30 is mounted. Wherein, the washing drum 10 can contain water, and the washing drum 10 is provided with a drain hole which can be selectively closed or opened. That is, in this embodiment, the laundry treating apparatus has only the washing tub 10 without an outer tub, and the washing water is contained in the washing tub 10 during the washing of the laundry.

In one embodiment, referring to fig. 1 and fig. 2, the laundry processing apparatus further includes a casing 40 having an electromagnetic shielding layer 41, the electromagnetic shielding layer 41 can shield the electromagnetic wave generated by the electromagnetic heating device 30, the electromagnetic heating device 30 is disposed in the casing 40, the casing 40 is open towards one side of the washing drum 10, so that the electromagnetic wave generated by the electromagnetic heating device 30 is radiated outwards from the open position of the casing 40, i.e. the electromagnetic wave is radiated towards the direction of the washing drum, and the electromagnetic wave in the other directions is shielded by the electromagnetic shielding layer 41, so that the electromagnetic interference of the electromagnetic heating device 30 to other electrical components of the laundry processing apparatus can be reduced; moreover, the housing 40 protects the electromagnetic heating device 30 and prevents other parts from scratching the electromagnetic heating device 30.

In this embodiment, the cover 40 may be made of a metal material capable of absorbing electromagnetic waves, or may be made of a base mold made of other material incapable of absorbing electromagnetic waves, and the electromagnetic shielding layer 41 is formed by coating an inner wall or an outer surface of the base mold with a material capable of absorbing electromagnetic waves, such as a conductive paint, or a metal shell capable of absorbing electromagnetic waves is covered on the outer side of the base mold and serves as the electromagnetic shielding layer 41.

The electromagnetic shielding principle of the electromagnetic shielding layer 41 is as follows: when the electromagnetic wave reaches the inner surface of the electromagnetic shielding layer 41, the incident electromagnetic wave is reflected due to the impedance discontinuity at the interface between the air and the electromagnetic shielding layer 41; the electromagnetic waves that enter the electromagnetic shielding layer 41 without being reflected by the surface of the electromagnetic shielding layer 41 are attenuated, i.e. absorbed, by the material of the electromagnetic shielding layer 41 during the forward propagation inside the electromagnetic shielding layer 41; when the residual electromagnetic waves that have not been attenuated in the electromagnetic shielding layer 41 are transmitted to the outer surface of the electromagnetic shielding layer 41, they will be reflected again when encountering the interface where the impedance of the electromagnetic shielding layer 41-air is discontinuous, and they will return back to the inside of the electromagnetic shielding layer 41. In summary, the electromagnetic shielding layer 41 attenuates electromagnetic waves mainly based on reflection of electromagnetic waves and absorption of electromagnetic waves.

In one embodiment, the electromagnetic shielding layer 41 is made of a low resistivity metal material, such as copper, aluminum, steel, etc., which generates eddy currents, thereby achieving the electromagnetic shielding effect.

In one embodiment, the laundry treating apparatus further includes a cover plate that is permeable to electromagnetic waves, i.e., the cover plate is not capable of shielding electromagnetic waves. The cover plate is sealed and arranged at the opening of the housing 40 to seal the electromagnetic heating device 30 in the housing 40, so that the waterproof performance of the electromagnetic heating device 30 can be improved. It should be noted that a hole for avoiding an electric wire is provided in the housing 40 or the cover plate so as to supply power to the electromagnetic heating device 30.

In other embodiments, the open side of the cover 40 sealingly abuts against a surface of the support component 20. That is, the open side of the casing 40 is sealed by the support member 20, and there is no need to additionally provide a cover plate in the above embodiment, which can also improve the waterproof performance of the electromagnetic heating apparatus 30.

In an embodiment, referring to fig. 2, the casing 40 further includes an electrical insulating layer 42, and the electrical insulating layer 42 is disposed on an inner surface or an outer surface of the electromagnetic shielding layer 41, so that the casing 40 can perform electromagnetic shielding and electrical insulating effects, prevent other components from being in conductive contact with the electromagnetic heating device 30, and further improve the safety of the clothes processing apparatus. For example, a base model of the cover 40 is made of a plastic material, the base model is the electric insulating layer 42, and a material capable of absorbing electromagnetic waves is coated on the inner surface or the outer surface of the electric insulating layer 42 to form the electromagnetic shielding layer 41, or a metal shell capable of absorbing electromagnetic waves is covered on the outer side of the base model and serves as the electromagnetic shielding layer 41.

In one embodiment, the laundry treating apparatus includes a temperature detecting device and a control main board electrically connected, the temperature detecting device detects the temperature of the washing drum 10. Because the washing drum 10 and the temperature detection device move relatively, the temperature detection device does not contact with the washing drum 10, but detects the air temperature on the outer surface of the washing drum 10 at a short distance, and indirectly acquires the temperature of the washing drum 10 according to the corresponding relation between the air temperature at the detection position and the actual temperature of the washing drum 10, and indirectly acquires the temperature of the washing water in the washing drum 10 according to the temperature of the washing drum 10. In this embodiment, the temperature detection device can be used to detect the temperature of the washing drum 10, regardless of whether the washing drum 10 is a perforated inner drum or a non-perforated inner drum.

The specific type of the temperature detection means is not limited, for example, an expansion type thermometer, a resistance type thermometer, a thermoelectric type thermometer, and the like, and is not limited herein.

The control mainboard is electrically connected with the temperature detection device to acquire the temperature information collected by the temperature detection device, and the control mainboard can control the electromagnetic heating part to be electrified or powered off. Specifically, when the temperature near the washing drum 10 reaches a preset temperature, the control main board controls the electromagnetic heating portion to be powered off. So on the one hand, can avoid the energy extravagant, on the other hand also has the safety alarm effect, prevents that the washing section of thick bamboo 10 temperature from continuously rising and bringing the incident.

It should be noted that, in the case that the laundry processing apparatus has the laundry drying function, when the laundry drying function is started, the electromagnetic heating device 30 may also heat the washing drum 10, so as to dry the laundry by the heat of the washing drum 10.
