Abstract

Disclosed is a method for controlling a hair dryer, the method for controlling a hair dryer, which comprises a main body part, a handle part, an operation part, a heating unit and a fan unit, according to one embodiment of the present invention comprising: an auto mode selection step in which a user operates the operation part so as to select, among a plurality of operation modes, an auto mode including a plurality of individual modes; and an auto mode performance step in which the plurality of individual modes are consecutively performed, wherein at least one among the temperature and speed of discharged gas is set to be different for each of the plurality of individual modes, and in the auto mode performance step, the heating unit and the fan unit control the temperature and speed of the discharged gas according to the respective settings of the plurality of individual modes.

Claims (45)

1 . A method for controlling a hair dryer including a main body including a gas outlet portion disposed thereon, a handle extending from the main body, an operation unit disposed on the main body or the handle, wherein one mode of a plurality of operation modes is able to be selected through the operation unit, a heater disposed inside the main body to adjust a temperature of discharge a gas discharged through the gas outlet portion, and a fan disposed inside the main body or the handle to adjust a speed of the discharged gas, the method comprising:

selecting an automatic mode for manipulating, by a user, the operation unit to select the automatic mode, the automatic mode being the one mode of the plurality of operation modes; and

executing the automatic mode, the automatic mode being a mode for sequentially executing a plurality of individual modes,

wherein at least one of the temperature or the speed of the discharged gas varies based on respective ones of the plurality of individual modes,

wherein when executing the automatic mode, the heater and the fan respectively adjust the temperature and the speed of the discharged gas based on a setting of each of the plurality of individual modes.

2 . The method of claim 1 ,

wherein the plurality of individual modes include a scalp drying mode and a hair drying mode, and

wherein the executing of the automatic mode includes:

a scalp drying operation for adjusting, by the heater, the temperature of the discharged gas to a first temperature and adjusting, by the fan, the speed of the discharged gas to a first speed based on the scalp drying mode; and

a hair drying operation for adjusting, by the heater, the temperature of the discharged gas to a second temperature higher than the first temperature and adjusting, by the fan, the speed of the discharged gas to the first speed based on the hair drying mode after the scalp drying operation.

3 . The method of claim 2 , wherein the plurality of individual modes further include a styling mode,

wherein the executing of the automatic mode further includes:

a styling operation for adjusting, by the heater, the temperature of the discharged gas to a third temperature higher than the second temperature and adjusting, by the fan, the speed of the discharged gas to a second speed lower than the first speed based on the styling mode after the hair drying operation.

4 . The method of claim 3 , wherein the plurality of individual modes further include a cooling mode,

wherein the executing of the automatic mode further includes:

a cooling operation for adjusting, by the heater, the temperature of the discharged gas to a fourth temperature lower than the first temperature and adjusting, by the fan, the speed of the discharged gas to a third speed equal to or lower than the second speed based on the cooling mode after the styling operation.

5 . The method of claim 4 , wherein the executing of the automatic mode further includes:

a repetition operation for repeatedly executing the styling mode and the cooling mode after the cooling operation.

6 . The method of claim 5 , wherein the executing of the automatic mode executes a next individual mode when an execution time of a currently executed individual mode among the plurality of individual modes is equal to or greater than a reference time preset for the currently executed individual mode.

7 . The method of claim 5 , wherein the executing of the automatic mode terminates a currently executed individual mode and then executing a next individual mode when the user selects individual mode switch by manipulating the operation unit.

8 . The method of claim 5 , wherein the hair dryer further includes a lighting portion,

wherein the lighting portion is disposed on the main body to emit light in a plurality of colors, and

wherein when executing the automatic mode, the lighting portion emits light in different colors respectively in the plurality of individual modes.

9 . The method of claim 8 , wherein the hair dryer further includes a display,

wherein the display is disposed on the main body to display a current operation state of the hair dryer, and

wherein when executing the automatic mode, the display displays a currently executed individual mode and at least one of the temperature or the speed of the discharged gas.

10 . The method of claim 9 , wherein when executing the automatic mode, at least a portion of the display emits light in a color corresponding to the color emitted by the lighting portion.

11 . A hair dryer comprising:

a main body including a gas outlet portion disposed thereon;

a handle extending from the main body;

an operation unit disposed on the main body or the handle, wherein one of a plurality of operation modes is able to be selected through the operation unit;

a heater disposed inside the main body to adjust a temperature of a gas discharged through the gas outlet portion;

a fan disposed inside the main body or the handle to adjust a speed of the discharged gas; and

a controller configured to, when an automatic mode among the plurality of operation modes is selected through the operation unit, control the heater and the fan to sequentially execute a plurality of individual modes, wherein at least one of the temperature or the speed of the discharged gas varies based on the plurality of individual modes.

12 . The hair dryer of claim 11 , further comprising:

a lighting portion disposed on the main body to emit light in different colors respectively in the plurality of individual modes.

13 . The hair dryer of claim 12 , further comprising:

a display disposed on the main body to display a currently executed individual mode and at least one of the temperature or the speed of the discharged gas.

14 . The hair dryer of claim 13 , wherein the display includes an individual mode display portion having a shape of a ring extending along a rim of the display,

wherein the individual mode display portion is divided into a plurality of lighting sections along an extension direction,

wherein the plurality of lighting sections respectively and sequentially correspond to the plurality of individual modes along the extension direction, and

wherein the individual mode display portion is configured such that n lighting sections from a first lighting section corresponding to an individual mode firstly executed in the automatic mode among the plurality of lighting sections to an n-th lighting section corresponding to a currently executed n-th individual mode are lit.

15 . The hair dryer of claim 11 , wherein the handle includes a gas inlet portion disposed at an end portion thereof in communication with the gas outlet portion,

wherein the hair dryer further includes a gas flow path extending from an interior of the handle to an interior of the main body and communicating the gas inlet portion with the gas outlet portion, and

wherein the fan is disposed on the gas flow path inside the handle.
