Hereinafter, preferred embodiments of a hair dryer having a mode function according to the present invention will be described in detail with reference to the accompanying drawings.

3 to 11, a hair dryer having a mode function according to the present invention includes a housing 100, a blower 200, a blowing passage 300, a blowing passage opening / closing means 400 A proximity sensor 500, a user operation unit 600, and a control unit 700.

As shown in FIGS. 3 and 4, the housing 100 has a discharge port 110 at the front thereof, a suction port 120 for sucking outside air at the rear thereof, and a handle 130 at a lower portion thereof. A blowing passage 300, a blowing passage opening and closing means 400 and a control unit 700. The proximity sensor 500 and the user operating unit 600 are installed outside the blower 200, An electric wire 60 is connected to the lower portion of the handle 130 to supply commercial power to the user operation unit 600 and the control unit 700, which will be described later.

4, the blower 200 includes a blowing fan 210 rotatably installed in the suction port 120 of the housing 100 to suck outside air by a rotational force, A blower fan driving motor 220 is provided. The blowing fan driving motor 220 is electrically connected to the user operation unit 600 and the control unit 700 to be described later and is capable of controlling the speed of the hot wind, A motor can be used.

4, the blowing passage 300 is provided with a hot air path 310 (see FIG. 4) in which a heating element 311 is fixed to discharge the external air supplied from the blower 200 to the discharge port 110 by hot air, hot air or natural air, And a natural air passage 320 for discharging the outside air while being separated from the hot air passage 310. The heating element 311 is fixed to the hot air path 310 via a support plate 312, and a coil type nichrome wire may be used.

The reason for including the hot air path 310 and the natural air path 320 is that the conventional hair dryer has a structure in which hot air or natural air is discharged as a heating element fixed to one air passage is turned on and off However, in the case of a single air passage, when the heating element is switched from a hot air to a natural air, power is cut off to the heating element. However, since hot air is discharged while the heating element is cooled, it takes a long time to convert from hot air to natural air. In order to solve such a problem, the present invention is characterized in that a natural wind path 320 is provided separately from the hot wind path 310, and the hot wind path switch 410 and the natural wind path switch 420 of the blowing path opening / The heating device 311 is supplied with power only while the hot air passage 310 is opened and when the natural air is discharged, only the natural air passage 320 is opened and the air is blown through the blower 200 By discharging the delivered external air as it is, the time from the hot air to the natural air can be drastically reduced compared to the prior art.

The outlet of the hot air path 310 and the natural air path 320 is connected to the air outlet 310 so that the air of the hot air path 310 and the natural air path 320 is mixed with the air outlet 300, And an air mixing passage (330) which is combined with the passage and narrowed in width and then spreads. This is for mixing the hot air of the hot air path 310 and the natural air of the natural air path 320 when the hot air is discharged to the discharge port 110. The hot wind or the natural wind is discharged to the discharge port 110 and the hot wind or the natural wind is discharged only to the part of the discharge port 100 due to the hot wind path 310 and the natural wind path 320, 110) in the middle of the center.

As shown in FIGS. 4 and 8 to 10, the blowing passage opening and closing means 400 is provided with an inlet of the hot air path 310 to open and close the hot air path 310 and the natural air path 320 of the air passage 300, And a natural-flow switch 420 for opening and closing the inlet of the natural-flow channel 320, respectively. Each of the hot air path switch 410 and the natural air path switch 420 may be electrically connected to the user operation unit 600 and the control unit 700 to be described later. For example, the hot-air path switch 410 and the natural-path switch 420 are connected to the hot air path 310 and the natural air path 320, respectively, to open and close the hot path 310 and the natural path 320, Or a solenoid valve or a motor-operated valve having an open-closing membrane 411, Here, the solenoid valve (or solenoid valve) refers to a valve using electromagnetic force, and the electric valve refers to a valve using rotational force of an electric motor.

3 to 5, the proximity sensor 500 is fixed to the discharge port 110 to detect a proximity distance between the discharge port 110 of the housing 100 and the user, and an infrared sensor or an ultrasonic sensor is used . Here, the proximity distance between the discharge port 110 and the user refers to the distance between the scalp and the hair of the user due to the characteristics of the use of the hair dryer. The reason for detecting the proximity distance is that the controller 110 The heating element 311 and the air passage opening and closing means 400 through the normal mode 721, the proximity mode 722 and the remote mode 723 of the distance sensing mode 720 included in the air conditioner 700, It is for automatic control. On the other hand, the proximity sensor 500 is powered by the power button 610 of the user operation unit 600, which will be described later.

3 to 6, the user operation unit 600 includes a power button 610 that is fixed to the handle 130 of the housing 100 and turns on and off the power according to a user's operation, A manual mode button 620 provided with a hot air button 621, a hot air button 622 and a natural air button 623 so that hot air, hot air or natural air is manually discharged from the outlet 110, And a distance detection mode button 630 for automatically changing or discharging hot air or natural air to the outlet 110 or automatically turning off the power. Here, the power button 610, the manual mode button 620, and the distance sensing mode button 630 may be applied to a sliding or pushing mode, and may transmit an input signal to a controller 700, ), The heating element 311 and the air passage opening / closing means 400 are manually or automatically controlled. The operation according to each button input configured in the user operation unit 600 will be described in detail in the control unit 700 to be described later.

The control unit 700 receives the detection values of the proximity sensor 500 and the input signals of the user operation unit 600 as shown in FIGS. 4, 5 and 7 and outputs the detection signals to the blowing fan driving motor 220, the heating elements 311 And the air passage opening / closing means 400. The air passage opening / To this end, the manual mode button 620 is operated in accordance with the input signals of the hot air button 621, the hot air button 622 or the natural air button 623 of the manual mode button 620 so that the hot air, A manual mode 710 for transmitting a control signal to the air passage opening and closing means 311 and the air passage opening and closing means 400 and a control means for comparing a detection value of the proximity sensor 500 with a previously stored distance reference value, A control signal is supplied to the blowing fan driving motor 220, the heating element 311 and the blowing passage opening and closing means 400 so that the hot air or the natural air is automatically changed or discharged to the outlet 110 or the power is automatically turned off And a distance sensing mode 720 for transmitting.

Specifically, the manual mode 710 includes a hot wind mode 711, a hot wind mode 712, and a natural wind mode 713. The hot air mode 711 is a mode in which hot air is discharged to the outlet 110 when the input signal of the hot air button 621 is received from the manual mode button 620 provided in the user operation unit 600, The heating element 311 is supplied with power so as to open the hot air path opening and closing device 410 of the air passage opening and closing means 400 and close the natural path opening and closing device 420 of the air passage opening and closing means 400. 9, when receiving the input signal of the hot-air button 622 among the manual mode buttons 620 provided in the user's operation unit 600, the hot-air mode 712 causes the hot- And the hot air path switch 410 and the natural air path switch 420 of the air flow path switching means 400 are both opened. Here, the hot air mode 712 may control the intensity of the power supplied to the heating element 311 in a state in which only the hot air path switch 410 is opened, so that hot air having a lower temperature than the hot air temperature is discharged. 10, the natural-wind mode 713 is a mode in which when the input signal of the natural-style button 623 is received from the manual mode button 620 provided in the user operation unit 600, The blower unit 400 is connected to the blower unit 400 through the blower unit 400. The blower unit 400 is connected to the blower unit 400 through the blower unit 400, Open.

The distance detection mode 720 includes a normal mode 721, a proximity mode 722 and a remote mode 723 and receives an input signal from the distance detection mode button 630 of the user operation unit 600 . The normal mode 721 supplies power to the heating element 311 to discharge hot air to the discharge port 110 when the detected value of the proximity sensor 500 corresponds to the previously stored distance reference value, The hot wind switch 410 of the means 400 is opened and the natural wind switch 420 of the wind passage opening and closing means 400 is closed. In the normal mode 721, the hot air is automatically discharged to the discharge port 110 as in the control according to the hot air mode 711 of the manual mode 710. When the detected value of the proximity sensor 500 is less than the stored distance reference value, the proximity mode 722 cuts off the power supply to the heating element 311 so that natural air is discharged to the discharge port 110, The hot wind switch 410 of the passage opening and closing means 400 is closed and the natural wind switch 420 of the wind passage opening and closing means 400 is opened. In this proximity mode 722, natural wind is automatically discharged to the discharge port 110 as in the control according to the natural-wind mode 713 of the passive mode 710 in order to prevent damage of the user's scalp and hair due to hot wind. . Also, the remote mode 723 cuts off the power of the blowing fan driving motor 220 and the heating element 311 when the detected value of the proximity sensor 500 exceeds the previously stored distance reference value. In order to prevent unnecessary power consumption, the remote mode 723 automatically cuts off the power of the blowing fan driving motor 220 and the heating element 311. Here, the pre-stored distance reference value is stored in the memory so that it can be compared with the detection value of the proximity sensor 500 for the proximity distance between the discharge port 110 and the scalp or hair of the user. For example, When the distance reference value is set to 150 mm to 300 mm, the general mode 721 is applied when the distance between the discharge port 110 and the scalp or hair of the user is 150 mm to 300 mm, and less than 1 mm to 149 mm The proximity mode is applied, and when it is exceeded, that is, when it exceeds 301 mm, the remote mode is applied and can be controlled in each mode.

Accordingly, as the distance sensing mode 720 of the controller 700 automatically switches to hot air or natural air or the power is automatically shut off according to the proximity distance to the user, the overheat of the heating element is reduced, Thereby preventing damage to the scalp and hair, and reducing power consumption.

The perfume pad 800 is detachably coupled to the natural wind path 320 of the ventilation passage 300 and the gel type phytoncide gel 810 or the oil type phytoncide oil is formed into a plurality of fragrance discharge holes 821 And filled in the pad 820. For this purpose, the natural wind path 320 is formed with a fixing protrusion 321 protruding upward and downward so that the perfume pad 800 can be inserted and fixed, and an insertion hole 322 penetrating downwardly of the housing, The housing 100 further includes an opening / closing button 140 for opening and closing the insertion hole 322. 13 and 14, when the insertion hole 322 is opened through the opening / closing button 140, the perfume pad 800 is inserted into the fixing protrusion 321 formed in the natural air passage 320, And then the insertion hole 322 is closed again through the opening / closing button 140 so that the fragrance pad 800 can be kept fixed to the natural airflow path 320.

Here, phytoncide is a term created in Russian by the combination of phyton (meaning "plant") and cide (meaning "killing"), and all plants are bacteria and insects And the antimicrobial, insecticidal, and bactericidal substance emitted from the plant is phytoncide. These phytoncides are 100% natural substances that are difficult to artificially synthesize or combine with phenol compounds including terpenes, alkaloids, and glycosides. They are rapidly absorbed by humans through the forest bath, It is a pure natural healing therapy which has various effects such as strong antimicrobial and antifungal action without stress, stress relieving, sedative action of the skin, induction of a sleeping face, improvement of allergic skin disease and increase of immune function.

Accordingly, the hair dryer having the mode function according to the present invention can form the fragrance pad 800 filled with the phytoncide gel or the oil for the busy modern man who can not often take a forest bath, so that the user can dry and stylize the hair, The fragrance containing the ingredient can be discharged to relieve the mind and body of the user, relieve stress, and alleviate the dermatitis.

In addition, the fragrance pad 800 is positioned in front of the sprinkler 200, unlike the fragrance device, in which the fragrance is simply connected to the rear of the blower or the blowing passage provided with the heating element, The phytoncide flavor can be discharged to the discharge port 110 together with the natural air while being detachably attached to the natural air passage 320 of the discharge port 300, There is a unique effect.

Specifically, the power supply mode 731 is set to the blowing fan driving motor 220 so that the blowing fan driving motor 220 is operated when the detected value of the gyro sensor 900 corresponds to the pre-stored tilt angle reference value It supplies power automatically. When the detected value of the gyro sensor 900 does not correspond to the pre-stored tilt angle reference value, the blowing fan driving motor 220 is turned off so that the blowing fan driving motor 220 is not operated. The power of the power source is automatically shut off. Here, the pre-stored tilt angle reference value is stored in the memory so that it can be compared with the detected value of the gyro sensor 900 with respect to the tilt angle of the housing 100 toward the user. For example, If the tilting angle reference value is set to + 70 ° to -80 ° in the vertical direction of the user's parietal reference, when the tilting angle of the outlet 110 of the housing 100 towards the user is + 70 ° to -80 °, The power supply mode 731 is applied and when the outlet 110 of the housing 100 is excessively directed upward or downward or in the opposite direction to the user side, And can be controlled in each mode. The user operation unit 600 and the controller 700 may be designed so that the gyro mode 730 can be applied in parallel with the manual mode 710 or the distance detection mode 720. [

Accordingly, the user can easily supply or block the power source by tilting the discharge port 110 of the housing 100 up and down with only the snap of the wrist, thereby stopping the operation of the blower 200 for a while. Unnecessary power consumption of the blower 200 can be reduced if the user does not need to operate the button of the user operating unit 600 and the wind discharged from the discharge port 110 is not directed to the user's scalp and hair.

Accordingly, the hair dryer having the mode function according to the present invention is provided with the ventilation passage 300, the hot air passage switch 410, and the ventilation passage opening / closing valve 300, which are provided with the first hot air passage 310, the natural air passage 320, There is an effect that the natural wind can be quickly converted from the hot wind to the natural wind through the switch 420. [

Second, since the proximity sensor 500, the user operation unit 600, and the control unit 700 are automatically converted to hot air or natural air according to the proximity distance to the user or the power is controlled, the overload of the heating element is reduced It is possible to prevent damage to the user's scalp and hair, and to reduce power consumption.

Third, since the phytoncide fragrance is discharged together with the natural air through the ventilation passage 300 and the fragrance pad 800 each having the hot air path 310 and the natural air path 320, the fragrance of the fragrance can be prevented, In addition, there is an effect that the user's mind and body can be stabilized, stress can be relieved, and dermatitis can be alleviated.

Fourth, power is automatically controlled according to the tilt angle through the user operating unit 600, the controller 700, and the gyro sensor 900, thereby reducing unnecessary power consumption.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
