Apparatuses and methods for drying objects are provided. The apparatus can comprise a housing configured to provide an airflow channel having an airflow inlet and an airflow outlet, an airflow generating element configured to effect an airflow through the airflow channel, and one or more radiation energy sources configured to generate infrared radiation and direct the infrared radiation toward an exterior of the housing. At least a portion of at least one of the one or more radiation energy sources does not contact the airflow channel or the airflow, thereby maintaining an operating temperature of the radiation energy source within a predetermined range.

A dryer for drying hair or clothes is disclosed. The dryer includes a head and a handle attached to the head. The dryer further includes ultrasonic devices, a controller, a vacuum pump, and a reservoir. The head has a surface on which inlet holes are formed. The ultrasonic devices are positioned on the surface of the head. The ultrasonic devices produce ultrasonic vibrations that break down water molecules into mist. The controller controls an operation of the ultrasonic devices.

An example skincare device includes a main body having a first side, a second side, an intermediate portion, a groove, a light source, a motor, a temperature control unit, and a user control configured to control one or more of the light source, motor, and temperature control unit. The skincare device can provide heat, cool, light, and/or vibrational therapy to a user's skin.

Disclosed is an ultraviolet (UV) curing apparatus for nail art, which is configured to focus-irradiate UV light to a curing material coated on fingernails or toenails and to quickly cure the curing material. The disclosed UV curing apparatus comprises: a housing having a receiving space in which user's fingernails or toenails are received; a light source, installed in the housing, for irradiating UV light rays; an optical module provided with a focusing lens for focusing the light rays irradiated from the light source to a target position in the receiving space; and a scanning unit, installed in the housing, for driving the optical module to be capable of reciprocating within the housing in one scanning direction, to allow the target position to move to the entire region of user's fingernails or toenails received in the receiving space.

The diffuser includes a diffusing case having a rear side removably coupled to a main body of a hair dryer. Fluid discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side and discharged from a front side of the diffusing case. A light irradiator is provided inside the diffusing case to irradiate light toward the front side of the diffusing case, and a light diffusion frame is provided in front of the light irradiator. The light irradiated from the light irradiator is diffused while forwardly penetrating the light diffusion frame.

A hair dryer includes a main body, a handle, and a diffuser. The diffuser includes a diffusing case having a rear side coupled to the main body. The main body is provided such that a front end of an outer wall surrounds a gas or air outlet, and a first coupling portion coupled with the diffuser is provided at the front end. The diffusing case includes a second coupling portion coupled to the first coupling portion while surrounding a gas or air inlet hole defined at the rear side. The first coupling portion includes a power transmitter to supply power to the diffuser, and the second coupling portion includes a power receiver to receive the power from the power transmitter.

A diffuser for a hair dryer includes a diffusing case, a guide frame provided inside the diffusing case to guide a flow of gas introduced into the diffusing case, a light irradiator provided inside the diffusing case and in front of the guide frame to irradiate light toward a front side of the diffusing case, and a discharge cover provided at the front side of the diffusing case. The discharge cover includes a gas discharge hole to discharge the gas inside the diffusing case to outside. The discharge cover includes a plurality of massage protrusions to press a target located in front of the discharge cover.

A diffuser includes a diffusing case having a rear side removably coupled to a main body of a hair dryer. Gas discharged from the main body is introduced into the diffusing case through a gas inlet hole defined at the rear side. The gas introduced into the diffusing case is discharged from a front side of the diffusing case. The diffusing case has a concave or curved structure such that an inner diameter of the diffusing case increases in a forward direction. A guide frame provided inside the diffusing case to guide a flow of the introduced gas includes a diffusion portion or protrusion provided to face the gas inlet hole to diffuse the gas introduced through the gas inlet hole.

A hair dryer includes a main body, a handle, and a diffuser. The diffuser includes a diffusing case. The main body is provided such that a front end of an outer wall surrounds the gas outlet, a first coupling portion coupled with the diffuser is provided at the front end, and the diffusing case includes a second coupling portion coupled to the first coupling portion while surrounding a gas inlet hole defined at a rear side. The first coupling portion includes a wireless power transmitter to wirelessly supply power to the diffuser, and the second coupling portion includes a wireless power receiver to wirelessly receive the power from the wireless power transmitter.

A diffuser for a hair dryer includes a diffusing case having a rear side removably coupled to a main body of the hair dryer. Air or fluid discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side. A n open surface is defined at a front side of the diffusing case such that the air introduced into the diffusing case is discharged to an outside through the open surface. The diffusing case includes a front circumferential portion surrounding the open surface. The front circumferential portion includes a first portion and a second portion. The first portion is at least partially located further forward of the second portion.
