Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the embodiment.

In addition, the following embodiments include the same components. Accordingly, in the following, common reference numerals are given to these similar components, and redundant description is omitted.

(first embodiment)

As shown in fig. 1, the blower 10 according to the present embodiment includes a blower main body 20 in which an air flow passage 22 is formed, and an elongated grip portion 30 which is a portion gripped by a hand of a user U (not shown). Although not shown, a power supply line (not shown) for connection to an external power supply or the like is drawn from the distal end portion of the grip portion 30.

In the present embodiment, the grip 30 is formed integrally with the blower main body 20, and the blower main body 20 and the grip 30 form a substantially T-shaped appearance. At this time, the grip 30 is provided integrally with the blower body 20 so that the extending direction of the air flow path 22 (the flow direction of the air flow) is a direction intersecting the longitudinal direction of the grip 30.

The grip 30 may be provided integrally with the blower main body 20 so as to have a substantially T-shaped appearance by the blower main body 20 and the grip 30.

The grip 30 may be rotatably connected to the blower main body 20, and the blower main body 20 and the grip 30 may have a substantially T-shaped or substantially L-shaped appearance when in use.

The blower main body 20 includes a main body case 21 having a hollow interior, and the main body case 21 constitutes an outer shell of the blower main body 20.

On the other hand, the grip portion 30 includes a grip portion side case 31 formed in a hollow shape, and the grip portion side case 31 constitutes an outer shell of the grip portion 30.

As described above, in the present embodiment, the main body case 21 and the grip portion side case 31 constitute at least a part of the case 40 forming the outer shell of the blower 10.

The case 40 can be formed by joining a plurality of divided bodies, for example. A cavity is formed in the case 40, and various electric devices are housed in the cavity.

In the present embodiment, an air flow passage 22 is formed from an air inlet 22a to an air outlet 22b formed at one end (right side) in the longitudinal direction (left-right direction in fig. 1) in the main body casing 21 of the blower main body 20. That is, an air flow path 22 having an inlet 22a and an outlet 22b on both sides is provided inside the main body casing 21 of the blower main body 20.

An air blowing portion 23 is disposed on an upstream side (a side close to the suction port 22a) in the air blowing passage 22, and the air blowing portion 23 blows out the air introduced from the suction port 22a from the discharge port 22 b. The air blowing unit 23 may be configured to include, for example, a fan (not shown) disposed on an upstream side in the air blowing passage 22 and a motor (not shown) disposed on a downstream side of the fan to drive the fan. With this configuration, when the fan is driven by supplying current to the motor and rotated, an air flow (air blow) is formed which flows into the air blow flow path 22 from the outside through the air inlet 22a, passes through the air blow flow path 22, and is discharged to the outside through the air outlet 22 b.

A heating unit 24 for heating the air (air) is disposed downstream of the air blowing unit 23 (on the side closer to the discharge port 22b than the air blowing unit 23). When the heating unit 24 is operated, the air flow (air blow) formed by the air blowing unit 23 is heated, and warm air is blown out from the outlet 22 b. As the heating unit 24, for example, a heater (not shown) formed by winding a strip-shaped and wave-plate-shaped resistor along the inner circumference of the body casing 21 of the blower body 20 is used.

ON the other hand, a switch unit 32 for switching between ON ("ON") and OFF ("OFF") of the power supply is housed in a hollow in the grip unit side case 31 of the grip unit 30.

The switch unit 32 is configured to be capable of switching the open/close state of the internal contacts by operating an operator 33 exposed on the surface of the grip unit side housing 31.

In the present embodiment, an electrically-charged particle generating section 25 for generating electrically-charged particles such as mist and metal particles is accommodated in the air flow passage 22. Further, the charged particle generating section 25 may not be provided in the air blowing flow path 22.

With the hair dryer 10 having such a configuration, if the user U (not shown) directs warm air discharged from the discharge port 22b to the hair H (the hair of the user U or the hair of a person other than the user U), the hair H of the subject person that is wet by shampooing or the like can be dried.

In this case, generally, the user U heats the hair H of the subject person by directing warm air to a plurality of portions of the hair H of the subject person while variously changing the posture of the blower 10, thereby drying the whole hair H of the subject person.

In the present embodiment, the hair dryer 10 includes a hair temperature measuring unit 52 for measuring the temperature of the hair H and a notification unit 51 for notifying the state of the hair H. The hair dryer 10 further includes a timer 54 for counting the drying time of the hair H, and a calculation unit 53 for calculating an output to the notification unit 51 based on the output result output from the hair temperature measurement unit 52.

As shown in fig. 2, the output result (the measured value of the temperature of the hair) measured by the hair temperature measuring unit 52 is input to the computing unit 53, and the count value (time measurement value) counted by the timer 54 is input to the computing unit 53. The calculation unit 53 controls the notification unit 51 based on the measured value of the temperature of the hair to be input and the time measured value.

In the present embodiment, the hair temperature measuring unit 52 is provided outside the ejection port 22 b. Specifically, the hair temperature measuring unit 52 is provided on the lower side (the gripping unit 30 side) outside the discharge port 22 b. As the hair temperature measuring unit 52, for example, an infrared sensor can be used.

In the present embodiment, as shown in fig. 1, the hair temperature measuring unit 52 is set such that the direction of the detection axis a is along the blowing direction W of the warm air blown out from the blow-out port 22 b.

That is, in the present embodiment, the hair temperature measuring unit 52 is provided at a location outside the area of the air flow path 22 (a location where the warm air does not directly face the location), and the direction of the detection axis a of the hair temperature measuring unit 52 is set to be a direction along the air flow direction W of the warm air discharged from the discharge port 22 b.

In general, when the hair H is dried using the hair dryer 10, warm air is directed to a plurality of portions of the hair H to heat the hair H while variously changing the posture of the hair dryer 10 as described above.

At this time, the hair H may be dried by using the center of the warm air region, that is, by causing the warm air jetted from the central portion of the jetting port 22b to mainly face the hair H. In addition, the hair H may be dried by using an end portion of the warm air region, that is, by mainly directing warm air discharged from the peripheral edge portion of the discharge port 22b toward the hair H.

Here, for example, a case where the hair temperature measurement unit 52 is disposed on the warm air axis, that is, in the air supply flow path 22 (a portion directly opposed by warm air) will be described together with fig. 3. As shown in fig. 3 (B), when the hair H is dried using the center of the warm air region, a large amount of hair H can be detected in the hair temperature measuring section 52 in the detection range (field of view: measurement region) 52a, and the hair temperature can be detected with high sensitivity by the hair temperature measuring section 52. However, as shown in fig. 3 (C), when the hair H is dried using the end of the warm air region, the hair H existing in the range (field of view: measurement region) 52a that can be detected by the hair temperature measurement unit 52 is reduced, and the hair temperature detection sensitivity may be lowered. In addition, the circular and trapezoidal regions shown by solid lines in fig. 3 are ejection ranges of warm air.

In contrast, in the present embodiment, the hair temperature measuring unit 52 is provided at a location outside the area of the air flow path 22 (a location where the warm air does not directly face the location), and the direction of the detection axis a of the hair temperature measuring unit 52 is set to be a direction along the air flow direction W of the warm air discharged from the discharge port 22 b.

As described above, the hair temperature measuring portion can be opposed to the hair H both in the case where the hair H is dried using the center of the warm air region as shown in fig. 4 (D) and in the case where the hair H is dried using the end of the warm air region as shown in fig. 4 (E). In fig. 4, the circular and trapezoidal regions indicated by solid lines also represent the warm air discharge range.

If the hair temperature measuring unit 52 is disposed outside the area of the air blowing flow path 22 and the direction of the detection axis a of the hair temperature measuring unit 52 is set to be along the air blowing direction W of the warm air blown out from the blow-out port 22b, the hair temperature detection sensitivity can be made more uniform when the hair dryer 10 is used.

As a result, even if the hair H is dried by various drying methods, the temperature of the hair can be measured with a substantially constant sensitivity, and the progress unevenness of the completion of the hair H can be suppressed.

Further, since the hair temperature measuring unit 52 is provided outside the area of the air flow path 22 (a portion not directly opposed to the warm air), it is possible to suppress noise that may be generated due to the influence of the warm air when measuring the hair temperature.

In the present embodiment, the hair temperature measuring unit 52 is provided on the gripping unit 30 side (lower side in fig. 1) outside the discharge port 22 b.

When the user U dries the user's own hair H using the end of the warm air region, the grip portion 30 side outside the discharge port 22b is often positioned on the hair H side. Therefore, by providing the hair temperature measuring unit 52 on the holding portion 30 side outside the discharge ports 22b, more hairs H can be present in the range (field of view) 52a that can be detected by the hair temperature measuring unit 52, and the temperature of the hairs H can be detected more reliably by the hair temperature measuring unit 52.

In the present embodiment, the notification unit 51 is formed by providing an LED as a light emitter on the outer surface of the main body case 21.

At this time, for example, in the case where the notification portion 51 is provided at the center of the blower main body 20, the user U needs to observe both the heated portion of the hair H and the notification portion 51 provided at the center of the blower main body 20 to recognize the state of the hair H. Therefore, when the notification portion 51 is provided at the center of the blower main body 20, the state of the hair H may not be easily recognized.

However, in the present embodiment, the notification portion 51 is provided over substantially the entire circumference around the discharge port 22b on the outer surface of the main body case 21. If the notification portion 51 is provided around the discharge port 22b on the outer surface of the main body case 21 in this manner, the notification portion 51 can be brought into the range of the visual field of the user U who is observing the heated portion of the hair H. Therefore, the user U can check the state of the hair H without moving the line of sight.

In this way, in the present embodiment, by providing the notification portion 51 around the discharge port 22b on the outer surface of the main body case 21, the user U can more easily recognize the state of the notification portion 51 (the state of the hair H facing the warm air).

In the present embodiment, an LED (light emitting body) is provided so that the notification portion 51 emits light of either blue or red. With this structure, for example, a blue LED and a red LED are arranged at one or more positions near the ejection port 22b on each of the front side surface and the back side surface of the main body casing 21. Further, the configuration can be obtained by arranging the blue LED and the red LED also at one or more positions on the opposite side of the grip portion 30 in the periphery of the ejection orifice 22b (upper portion of the periphery of the ejection orifice 22 b).

At this time, it is preferable that a plurality of blue LEDs and a plurality of red LEDs are alternately provided along the periphery of the discharge port 22b and that LEDs of a certain color are lit. In this way, when only the blue LED is turned on, the notification unit 51 emits blue annular light, and when only the red LED is turned on, the notification unit 51 emits red annular light.

The notification unit 51 is controlled to emit blue or red light based on the state of the hair H. In the present embodiment, the notification unit 51 emits blue or red light based on the temperature of the hair H. Specifically, when the temperature of the hair H is lower than a predetermined temperature (target temperature described later), the notification unit 51 is caused to emit blue light, and when the temperature of the hair H is equal to or higher than the predetermined temperature (target temperature described later), the notification unit 51 is caused to emit red light.

In this way, in the present embodiment, the notification portion 51 is provided around the discharge port 22b, and the notification portion 51 is caused to emit blue or red light based on the state of the hair H (the hair temperature measured by the hair temperature measurement portion 52). In this way, when the hair dryer 10 is used, the radiant light emitted from the light emitter is reflected by the hair H, and the heated portion of the hair H appears to be colored by the emission color of the notification portion 51, so that the user U can recognize the state of the hair H more intuitively.

The light-emitting body is not limited to the LED, and any member may be used as long as it emits light. The color of the emitted light is not limited to blue and red, and can be selected as appropriate.

Note that the notification method of the notification unit 51 is not limited to the emission of light from the light emitter, and for example, notification may be performed by a light emitter or sound.

The timer 54 counts the drying time of the hair H as described above.

The output result (the measured value of the temperature of the hair) measured by the hair temperature measuring unit 52 and the count value (the time measurement value) counted by the timer 54 are input to the computing unit 53 as described above, and the output to the notification unit 51 is computed. As such an arithmetic unit 53, for example, a microcomputer or the like provided on a control board can be used.

In general, when the user U dries the hair H using the blower 10, haircut such as bending to smooth the hair H and trimming the hair H is performed while drying the hair H, instead of simply drying the hair H.

In order to further improve the hair cutting effect, it is necessary to cut hair in a state where the temperature of the hair H is equal to or higher than the glass transition point G. Further, the glass transition point G is calculated based on the result (black painted point of fig. 5) assumed using a plurality of hair samples different in moisture content, and basically, the less the moisture content, the higher the glass transition point G.

In order to further improve the hair dressing effect of the hair H, it is preferable to more rapidly bring the hair H that is damp due to shampooing or the like (hair that has a large moisture content and a temperature lower than the temperature of the glass transition point G) into the range of the ideal region R. The reason is that if the time required to bring the wet hair H into the range of the ideal region R becomes long, the hair cutting effect may be reduced without smoothing out the bending of the hair H. The ideal region is a range in which the moisture content of the hair H is 11% to 13% and the hair temperature is 55 ℃ to 75 ℃ as shown in fig. 5.

In general, when the user U dries the hair H using the blower 10, the following operations are repeated: the hair H at a certain position is heated and then moved to other positions to heat the moved position, thereby gradually drying the whole hair.

Therefore, when focusing attention on the hair H at a certain portion in the entire hair, the heating → the heat release → the heating … is repeated at the portion, and the hair temperature is changed vertically (see fig. 6 and 7). Then, by repeating the heating → the heat release → the heating …, the hair temperature of the hair H at the specific portion is changed up and down and the moisture content is reduced, so that the hair H at the specific portion reaches the ideal region R shown in fig. 5.

In this case, in order to allow the hair H that is wet by shampooing or the like to reach the ideal region R more quickly, the total amount of heat applied to the hair H needs to be a predetermined amount of heat in a shorter period of time.

However, if the heat that damages the hair H (heat exceeding the damage limit temperature) is applied in a short time such as when 80 ℃ wind (hot wind) is applied to the same portion for 1 second or more, or when 75 ℃ wind (hot wind) is applied to the same portion for 3 seconds or more, the hair damage reduces the hair cutting effect.

Therefore, it is necessary to apply a predetermined amount of heat to the hair H in a shorter period of time while suppressing damage to the hair H.

Hereinafter, a control method of the notification unit 51 that can suppress damage to the hair H and can apply a predetermined amount of heat to the hair H in a shorter period of time will be described as an example. The method of controlling the notification unit 51 is not limited to the method described below, and the notification unit 51 can be controlled by various methods.

First, as shown in fig. 6, the following method can be used: the hair H is gradually dried by setting a temperature close to 75 ℃ which is the upper limit of the temperature of the ideal region R as a target temperature and moving the hair H to another part if the hair temperature becomes equal to or higher than the target temperature due to heating. If the method shown in fig. 6 is used, the hair H that is wet by shampooing or the like can reach the ideal region R relatively quickly, and therefore the hair dressing effect can be improved.

However, the hair H is difficult to warm due to the influence of vaporization heat in a state where the moisture content is high, and is easily cooled. Therefore, in the initial stage of drying the hair H, when drying is performed within the temperature range of the ideal region R, the amount of heat applied to the hair H (the area of the region surrounded by the portion having the hair temperature of 55 ℃ or higher and the transverse line of 55 ℃) becomes relatively small. Therefore, in the case of the method shown in fig. 6 (the method of setting the target temperature to a fixed temperature), the time until the hair H converges on the ideal region R may become long. Further, if the time until the hair H converges on the ideal region R becomes long, the hair H may not be straightened and the hair H may not be straightened.

Therefore, as a control method for the notification unit 51, it is preferable to use a method capable of causing the hair H to reach the ideal region R more quickly than the method shown in fig. 6.

For example, as shown in fig. 7, it is preferable that the temperature to be raised by heating the hair H is set as a target temperature, and the calculation unit 53 calculates the target temperature based on the drying time from the start of drying the hair H.

Specifically, in fig. 7, when the hair H is wet (when the moisture content is high), the target temperature is set to a temperature higher than the upper limit (75 ℃) of the temperature of the ideal region R in the initial stage of drying, focusing on the fact that the hair temperature immediately drops when heat is released even when the hair H is heated. The target temperature at the end of drying after the elapse of time from the start of drying is set to a temperature lower than the target temperature at the initial stage of drying.

That is, the calculation unit 53 calculates the target temperature so that the temperature at the end of drying is lower than the temperature at the start of drying.

Fig. 7 illustrates a case where the target temperature is gradually decreased with the passage of time from the start of drying.

That is, fig. 7 illustrates the maximum temperature at which the target temperature at the drying start time is the highest temperature and the minimum temperature at which the target temperature at the drying end time is the lowest temperature. The target temperature gradually decreases with time from the highest temperature at the drying start time to the lowest temperature, but after reaching the lowest temperature, the target temperature is a fixed value (lowest temperature) even after the passage of time.

The target temperature may be the lowest temperature at the end of drying (when the average time required for drying the hair H has elapsed from the start of drying), and may be the lowest temperature during drying.

Here, the maximum temperature of the target temperature can be set to, for example, about 80 ℃. The minimum temperature of the target temperature can be set to, for example, about 75 ℃ (a value close to 75 ℃ which is the upper limit of the temperature of the ideal region R).

The time required from the start of drying to the lowest temperature can be set, for example, within a range of 150 seconds to 300 seconds.

In this case, the time required from the start of drying to the lowest temperature may be set to a fixed time such as 200 seconds. Further, the time required from the start of drying to the lowest temperature may be changed as a result of the length of the hair selected by the user. For example, if the length of the hair selected by the user is long, the setting is made longer, and if the length of the hair selected by the user is short, the setting is made shorter.

In this way, if the hair H is heated until the target temperature calculated by the calculation unit 53 is reached, the hair H can be converged within the range of the ideal region R more quickly without applying heat exceeding the damage limit temperature to the hair H.

Note that the method shown in fig. 6 (the method of making the target temperature substantially constant without depending on the elapse of time) and the transition of the target temperature shown in fig. 7 are only examples of the control method for the notification unit 51, and the notification unit 51 can be controlled by other methods. For example, as shown in fig. 9, the target temperature may be gradually lowered (wavedly lowered) while being vibrated up and down. In this case, it is not necessary to set the target temperature at the drying start time point to the maximum temperature.

In addition, the target temperature may be changed in a stepwise manner so as to be a constant temperature for a predetermined time.

Next, an example of a method of controlling the notification unit 51 by the calculation unit 53 will be described with reference to fig. 8.

First, the power supply is turned on by operating the operator 33 of the hair dryer 10 and switching the open/close state of the internal contact of the switch unit 32.

Thereafter, the hair H is dried by directing warm air to the hair H at a predetermined position (step S11).

When the drying of the hair H is started, the timer 54 operates to count the drying time (step S12). Further, the timing for operating the timer 54 can be set as appropriate. For example, the counting may be started simultaneously with the power-on, or may be started after determining that drying has been started when a predetermined time has elapsed since the power-on.

When the drying time is counted, the count value (time measurement value) counted by the timer 54 is input to the calculation unit 53, and the calculation unit 53 calculates the target temperature based on the drying time (input count value: time measurement value) (step S13).

On the other hand, the hair temperature measuring unit 52 measures the temperature of the hair H (step S14). Then, the output result (the measured value of the temperature of the hair) measured by the hair temperature measuring unit 52 is input to the computing unit 53.

Then, the calculation unit 53 determines whether or not the temperature of the hair H measured by the hair temperature measurement unit 52 reaches the calculated target temperature based on the output result (the measured value of the temperature of the hair) output from the hair temperature measurement unit 52 (step S15). That is, the temperature of the hair H measured by the hair temperature measuring unit 52 is compared with the calculated target temperature.

Then, the arithmetic unit 53 controls the notification unit 51 based on the determination at step S15. Specifically, if the temperature of the hair H is less than the target temperature, the arithmetic unit 53 causes the notification unit 51 to emit blue light. Thereafter, the operations of step S13 to step S15 are repeated until the temperature of the hair H becomes equal to or higher than the target temperature. When it is determined in step S15 that the temperature of the hair H is equal to or higher than the target temperature, the arithmetic unit 53 causes the notification unit 51 to emit red light in step S16. The user U confirms that the notification unit 51 emits red light, and applies warm air to the hair H at another place to dry the hair H at the other place. In this case, the operations of step S13 to step S16 are repeated.

The above operation is repeated to dry the whole hair.

As described above, the blower 10 according to the present embodiment includes: a blower main body 20 having an air flow path 22 formed therein, the air flow path 22 having an inlet 22a and an outlet 22 b; an air blowing unit 23 disposed in the air blowing passage 22; and a heating unit 24 disposed in the air blowing passage 22 at a position closer to the discharge port 22b than the air blowing unit 23.

The hair dryer 10 further includes a hair temperature measuring unit 52 for measuring the temperature of the hair H, and a notification unit 51 for notifying the state of the hair H (hair temperature).

The notification portion 51 includes an LED (light emitting body) provided around the discharge port 22 b.

With this configuration, since the notification portion 51 can be brought into the range of the field of view of the user U who is observing the heated portion of the hair H, the user U can confirm the state of the hair H without moving the line of sight while using the hair dryer 10. As a result, the state of the hair H can be confirmed more easily.

Further, as described above, it is exemplified that the notification portion 51 is controlled to emit blue or red light based on the state of the hair H (hair temperature). However, when the user U is in a state of recognizing the hair H using the light emitters of two colors, it is not known when the hair H reaches a predetermined temperature, and therefore there is a possibility that the user U stops drying in the middle. The reason why the user U does not know when the hair H reaches the predetermined temperature is that if only the blue color is displayed in the notification unit 51, it is not known whether the hair H contains a large amount of water and takes time until the temperature rises or the temperature rises to a level at which the red color is immediately displayed.

Therefore, it is preferable for the user U to cause the light emitter of the notification unit 51 to emit light of three colors, i.e., blue, green, and red, as shown in fig. 10.

In fig. 10, when the hair temperature is lower than a predetermined temperature set in the range of 35 to 45 ℃, the notification portion 51 is caused to emit blue light, and when the hair temperature is higher than a predetermined temperature set in the range of 55 to 75 ℃, the notification portion 51 is caused to emit red light. When the hair temperature is between the two predetermined temperatures, the notification unit 51 is caused to emit green light.

In this way, if the light emitter of the notification unit 51 is caused to emit light of three colors, blue, green, and red, the hair H can pass by until the state of the hair H is recognized when the hair H is dried, and therefore the hair H can be dried by a more desirable drying method, and the usability of the hair dryer 10 can be further improved.

For example, the hair H can be dried as follows. First, when the hair is dried, the whole hair is dried gradually, and the blue light emitted from the notification portion 51 disappears. After that, if the notification unit 51 starts emitting red light, haircut (styling) is performed. Then, if the notification unit 51 emits red light over the entire hair, the drying is finished.

Further, a drying method according to the dryness, such as haircut, can be used in the stage of eighty percent drying.

(second embodiment)

The blower 10A according to the present embodiment basically has the same configuration as that of the first embodiment. Specifically, as shown in fig. 11A and 11B, the blower 10A includes a blower main body 20 having a blower flow path 22 formed therein, and the blower flow path 22 has a suction port 22a and a discharge port 22B. The blower 10A includes a blowing section 23 disposed in the blowing passage 22, and a heating section 24 disposed in the blowing passage 22 at a position closer to the discharge port 22b than the blowing section 23. The hair dryer 10A further includes a hair temperature measuring unit 52 for measuring the temperature of the hair H, and a notification unit 51 for notifying the state of the hair H.

In the present embodiment, the notification portion 51 also includes a light emitter provided around the discharge port 22b, and the notification portion 51 is formed by providing an LED as the light emitter on the outer surface of the main body case 21, as in the first embodiment.

Here, in the present embodiment, the light emitter of the notification portion 51 is provided not on the side surface (circumferential surface) of the main body case 21 on the side of the discharge port 22b, but on the end surface 21a on the downstream side of the main body case 21 (see fig. 11). In fig. 11, the light emitter of the notification unit 51 is shown as being embedded and fixed in a state of being exposed forward in the downstream-side end surface 21a of the main body case 21, but the light emitter may be attached to the downstream-side end surface 21a of the main body case 21 so as to protrude forward.

In this way, if the light emitter of the notification unit 51 is provided on the downstream-side end surface 21a of the main body case 21, the light from the light emitter can be directly irradiated to the hair H of the user U. That is, the entire region (light-emitting region 51a) where the light emitter emits light can be directly irradiated to the hair H.

In the present embodiment, a blue LED and a red LED can be used as the light emitter. The notification unit 51 can be controlled based on the temperature of the hair H so that the notification unit 51 emits blue or red light. In the present embodiment, when the notification portion 51 emits blue or red light based on the temperature of the hair H, the hair H emits blue or red light.

At this time, it is preferable to appropriately adjust the size of the light emitting region 51a, that is, the region of the hair H where the notified portion 51 emits light. For example, the light-emitting region 51a at a portion separated from the light-emitting body by a predetermined distance can be adjusted to be within a predetermined range by further mounting a lens or the like.

The light emitter may be provided on the downstream end face 21a of the main body case 21 in a state where the main optical axis direction a1 is substantially parallel to the blowing direction W of the warm air. However, as shown in fig. 11A, the light emitter is preferably provided on the downstream end face 21A of the main body casing 21 in a state where the main optical axis direction a1 intersects the blowing direction W of the warm air. In this way, the light-emitting region 51a located on the downstream side separated from the discharge port 22b of the blower 10A by a predetermined distance can be made to substantially coincide with the heating region of the hair H.

It is preferable that the predetermined distance is set based on a distance from the discharge port 22b to the hair H which is generally assumed when the hair dryer 10A is normally used. For example, if it is assumed that the distance from the discharge port 22b to the hair H, which is generally assumed when the hair dryer 10A is normally used, is 10cm to 20cm, an arbitrary distance until the distance from the discharge port 22b is 10cm to 20cm is set as the predetermined distance. In this way, the light-emitting region 51a at a position separated from the discharge port 22b by a predetermined distance can be made to substantially coincide with the heating region of the hair H.

Further, it is preferable that the warm air is directed toward the hair H at a distance from the discharge port 22b that is generally assumed when the hair dryer 10A is used, so that damage due to heat can be minimized and the hair H can be dried more efficiently. As described above, since the method of using the blower 10A is generally a more appropriate method of using the blower 10A, the light-emitting region 51a can be made to substantially coincide with the heating region of the hair H in a more appropriate use state of the blower 10A. As a result, the user U can be more clearly notified of the heated portion of the hair H during normal use (more appropriate use), so that the air of the blower 10A can be more efficiently directed toward the hair H, and the usability of the blower 10A can be further improved.

In the present embodiment, the hair temperature measuring unit 52 is also provided outside the area of the air flow path 22 (a portion not directly facing the warm air), and can suppress noise that may be generated due to the influence of the warm air when measuring the hair temperature.

The light emitter of the notification unit 51 and the hair temperature measurement unit 52 are arranged in parallel in a direction perpendicular to a plane including the axis of the grip portion 30 and the axis of the warm air (a direction orthogonal to the extending direction of the grip portion 30 and the blowing direction W of the warm air). Fig. 11A and 11B illustrate an example in which the light emitter and the hair temperature measurement unit 52 of the notification unit 51 are arranged side by side in the left-right direction (the width direction of the hair dryer 10A) on the upper portion of the downstream-side end surface 21A of the main body casing 21.

In the present embodiment, as shown in fig. 11A and 11B, the direction of the detection axis a of the hair temperature measuring unit 52 is substantially aligned with the main optical axis direction a1 of the light emitter of the notification unit 51. That is, the light-emitting body and the hair temperature measuring unit 52 of the notification unit 51 are arranged such that the direction of the detection axis a of the hair temperature measuring unit 52 is substantially parallel to the main optical axis direction a1 of the light-emitting body. At this time, the direction of the detection axis a also intersects the blowing direction W of the warm air.

In the present embodiment, the measurement region 52a of the hair temperature measuring unit 52 is also made to substantially coincide with the heating part of the hair H. Therefore, in the present embodiment, the heating portion of the hair H, the light emitting region 51a, and the measurement region 52a are substantially aligned within the distance (predetermined distance) between the hair H and the blower 10A when the blower 10A is normally used.

In this way, the light-emitting portion of the hair H when the hair dryer 10A is normally used can be substantially aligned with the measurement region 52a of the hair temperature measurement unit 52, and thus the hair temperature can be measured more accurately.

Further, the light-emitting portion of the hair H when the hair dryer 10A is normally used can be made substantially coincident with the measurement area 52a of the hair temperature measurement unit 52 and the heating portion of the hair H. In this way, the user U can more accurately recognize which part of the hair temperature is being measured and which part of the hair H is being heated, and thus can use the blower 10A more intuitively. As a result, the usability of the blower 10A can be further improved.

Further, if the light emitting body of the notification unit 51 and the hair temperature measurement unit 52 are arranged in parallel in the left-right direction (the width direction of the hair dryer 10A), the light emitting region 51a of the notification unit 51 and the measurement region 52a of the hair temperature measurement unit 52 are slightly shifted in the left-right direction as shown in fig. 11B.

However, when the hair H is dried by using the blower 10A, the hair H is often dried while swinging the blower 10A left and right. When the hair dryer 10A is swung left and right, the deviation in the left-right direction between the light-emitting region 51a of the notification unit 51 and the measurement region 52a of the hair temperature measurement unit 52 is cancelled. That is, in general, in a highly frequent use state (a state in which the hair H is dried while the blower 10A is swung left and right), the deviation between the light-emitting region 51a and the measurement region 52a can be canceled.

By arranging the light emitting body of the notification unit 51 and the hair temperature measurement unit 52 in parallel in the left-right direction (width direction of the hair dryer 10A), the influence of the left-right direction deviation between the light emitting region 51a and the measurement region 52a can be reduced during most of the time when the hair dryer 10A is used. That is, when the hair dryer 10A is used, it is possible to alleviate the difference between the hair temperature measured by the hair temperature measuring unit 52 and the actual hair temperature. As a result, the hair H can be dried more efficiently.

The hair dryer 10A further includes a timer 54 for counting the drying time of the hair H, and a calculation unit 53 for calculating an output to the notification unit 51 based on the output result output from the hair temperature measurement unit 52.

The output result (the measured value of the temperature of the hair) measured by the hair temperature measuring unit 52 is input to the computing unit 53, and the count value (time measurement value) counted by the timer 54 is input to the computing unit 53.

The calculation unit 53 controls the notification unit 51 based on the measured value of the temperature of the hair to be input and the time measured value.

Therefore, in the present embodiment, the notification unit 51 can be controlled by using the control method of the notification unit 51 exemplified in the first embodiment.

As described above, the present embodiment can also provide the same operation and effect as those of the blower 10 according to the first embodiment.

In the present embodiment, the light emitting region 51a of the light emitter is substantially aligned with the measurement region 52a of the hair temperature measurement unit 52.

In this way, the user U can more accurately recognize which part of the hair temperature is being measured, and thus can use the hair dryer 10A more intuitively. As a result, the usability of the blower 10A can be further improved.

(third embodiment)

The blower 10B according to the present embodiment basically has the same configuration as that of the first embodiment. That is, as shown in fig. 12, the blower 10B includes a blower main body 20 in which an air flow path 22 is formed, and the air flow path 22 includes an air inlet 22a and an air outlet 22B. The blower 10B includes a blowing section 23 disposed in the blowing passage 22, and a heating section 24 disposed in the blowing passage 22 at a position closer to the discharge port 22B than the blowing section 23. The hair dryer 10B includes a hair temperature measuring unit 52 for measuring the temperature of the hair H, and a notification unit 51 for notifying the state of the hair H. The hair dryer 10B includes a timer 54 for counting the drying time of the hair H, and a calculation unit 53 for calculating an output to the notification unit 51 based on the output result output from the hair temperature measurement unit 52.

Here, in the present embodiment, the notification unit 51 includes a light emitter provided around the suction port 22 a. The notification unit 51 may be formed by providing an LED as a light emitter on the outer surface of the main body case 21, as in the first embodiment.

Specifically, the notification portion 51 can be configured to emit light of either blue or red by alternately providing a plurality of blue LEDs and a plurality of red LEDs along the periphery of the suction port 22a and lighting the LEDs of either color.

The notification unit 51 is controlled to emit blue or red light based on the state of the hair H. In the present embodiment, the notification unit 51 emits blue or red light based on the temperature of the hair H.

The present embodiment described above can also provide the same operation and effect as those of the blower 10 described in the first embodiment.

In the present embodiment, the notification unit 51 includes a light emitter provided around the suction port 22 a.

By doing so, as shown in fig. 13, since the notification portion 51 can be reflected in the mirror when the user U dries the rear portion of the head, the state of the hair H can be confirmed more easily.

In the present embodiment, as described together with fig. 10, the light emitter of the notification unit 51 can be made to emit light of three colors, i.e., blue, green, and red.

(fourth embodiment)

The blower 10C according to the present embodiment basically has the same configuration as that of the first embodiment. That is, as shown in fig. 14, the blower 10C includes a blower main body 20 in which an air flow path 22 is formed, and the air flow path 22 includes an air inlet 22a and an air outlet 22 b. The blower 10C includes a blowing section 23 disposed in the blowing passage 22, and a heating section 24 disposed in the blowing passage 22 at a position closer to the discharge port 22b than the blowing section 23. The hair dryer 10C further includes a hair temperature measuring unit 52 for measuring the temperature of the hair H, and a notification unit 51 for notifying the state of the hair H. The hair dryer 10C further includes a timer 54 for counting the drying time of the hair H, and a calculation unit 53 for calculating an output to the notification unit 51 based on the output result output from the hair temperature measurement unit 52.

Here, in the present embodiment, the notification portion 51 includes a light emitter provided at the distal end portion of the grip portion 30. The notification unit 51 may be formed by providing an LED as a light emitter on the outer surface of the main body case 21, as in the first embodiment.

Specifically, the notification portion 51 can be configured to emit light of either blue or red by alternately providing a plurality of blue LEDs and a plurality of red LEDs along the periphery of the distal end portion of the grip portion 30 and lighting the LEDs of either color.

In the present embodiment, the notification unit 51 includes a light emitter provided at the distal end portion of the grip unit 30.

By doing so, as shown in fig. 15, since the notification portion 51 can be reflected in the mirror when the user U dries the rear portion of the head, the state of the hair H can be confirmed more easily.

(fifth embodiment)

The blower 10D according to the present embodiment basically has the same configuration as that of the first embodiment. That is, as shown in fig. 16, the blower 10D includes a blower main body 20 in which an air flow path 22 is formed, and the air flow path 22 includes an air inlet 22a and an air outlet 22 b. The blower 10D includes a blowing section 23 disposed in the blowing flow path 22, and a heating section 24 disposed in the blowing flow path 22 at a position closer to the discharge port 22b than the blowing section 23. The hair dryer 10D further includes a hair temperature measuring unit 52 for measuring the temperature of the hair H, and a notification unit 51 for notifying the state of the hair H. The hair dryer 10D includes a timer 54 for counting the drying time of the hair H, and a calculation unit 53 for calculating an output to the notification unit 51 based on the output result output from the hair temperature measurement unit 52.

In the

blowers

10, 10A, 10B, and 10C exemplified in the first to fourth embodiments, the notification portion 51 is provided in the blower main body 20, and the state of the hair H can be recognized by visually confirming the notification portion 51 directly or via a mirror.

However, depending on the user U, the hair H may be dried without looking at the mirror or dried in a downward state. In addition, the

blowers

10, 10A, 10B, and 10C exemplified in the first to fourth embodiments are not convenient for the user U.

Therefore, in the present embodiment, the following configuration is adopted: by providing the notification portion 51 separately from the blower main body 20, the user U who dries the hair H without looking at a mirror or dries the hair H in a downward state can easily recognize the state of the hair H.

Specifically, the notification unit 51 is provided in an information processing terminal such as a smartphone or a computer.

Note that the notification unit 51 need not be provided in the information processing terminal, and any form may be used as long as it is provided separately from the blower main body 20 and can notify the state of the hair H.

In fig. 16, the case where the information processing terminal provided with the notification unit 51 and the electric device (such as the operation unit 53) in the main body case are connected by wire is illustrated, but the information processing terminal provided with the notification unit 51 and the electric device (such as the operation unit 53) in the main body case may be connected wirelessly.

In the present embodiment, the notification portion 51 is provided separately from the blower main body 20.

In this way, since the notification unit 51 can be provided in a place that is easily visible to the user, the usability of the hair dryer 10D can be further improved.

The notification unit 51 is provided in the information processing terminal.

In this way, the state of the hair H can be displayed on the screen, and the usability of the blower 10D can be further improved.

As a notification method of the notification unit 51, various methods can be used. For example, the notification may be performed by lighting a light emitter or by sound. Further, the notification can be made by a light or sound.

In the case of performing notification by emitting light from the light emitting body, as described with reference to fig. 10, the light emitting body may be made to emit light of two colors of blue and red, or the light emitting body may be made to emit light of three colors of blue, green, and red.

(sixth embodiment)

The blower 10E according to the present embodiment basically has the same configuration as that of the first embodiment. That is, as shown in fig. 17, the blower 10E includes a blower main body 20 in which an air flow path 22 is formed, and the air flow path 22 includes an air inlet 22a and an air outlet 22 b. The blower 10E includes an air blowing portion 23 disposed in the air blowing passage 22, and a heating portion 24 disposed in the air blowing passage 22 at a position closer to the discharge port 22b than the air blowing portion 23. The hair dryer 10E further includes a hair temperature measuring unit 52 for measuring the temperature of the hair H, and a notification unit 51 for notifying the state of the hair H (hair temperature). The hair dryer 10E further includes a timer 54 for counting the drying time of the hair H, and a calculation unit 53 for calculating an output to the notification unit 51 based on the output result output from the hair temperature measurement unit 52.

The blower 10E is also provided with a usage environment temperature measurement unit 56 for measuring the temperature of the usage environment. As the usage environment temperature measurement unit 56, a room temperature sensor or the like that measures a room temperature (usage environment temperature) can be used.

As shown in fig. 18, the output result (the measured value of the temperature of the hair) measured by the hair temperature measuring unit 52 is input to the computing unit 53, and the count value (time measurement value) counted by the timer 54 is input to the computing unit 53. The output result (measured value of the room temperature (usage environment temperature)) measured by the room temperature measuring unit (usage environment temperature measuring unit) 56 is input to the calculating unit 53. As shown in fig. 18, the calculation unit 53 controls the notification unit 51 based on the measured value of the temperature of the hair to be input, the time measured value, and the measured value of the room temperature (use environment temperature).

Here, in the present embodiment, the calculation unit 53 adjusts the target temperature based on the room temperature (use environment temperature) measured by the room temperature measurement unit (use environment temperature measurement unit) 56.

Specifically, as shown in fig. 19, when the room temperature (use environment temperature) is high, the target temperature becomes high.

In the present embodiment, the calculation unit 53 calculates the target temperature to be heated based on the drying time counted by the timer 54, as in the first embodiment.

Further, the calculation unit 53 determines whether or not the temperature measured by the hair temperature measurement unit 52 has reached the target temperature based on the output result output from the hair temperature measurement unit 52, as in the first embodiment.

The calculation unit 53 controls the output to the notification unit 51 based on whether or not the temperature of the heated hair H reaches the target temperature, as in the first embodiment.

Therefore, in the present embodiment, even when the elapsed time from the start of drying is the same, the target temperature changes depending on the room temperature (use environment temperature).

In the present embodiment, the first temperature is set to a temperature higher than the room temperature (use environment temperature) measured by the room temperature measuring unit (use environment temperature measuring unit) 56, and the notification by the notification unit 51 is stopped when the temperature of the hair H measured by the hair temperature measuring unit 52 is lower than the first temperature (see fig. 20).

The first temperature can be set to a temperature higher than room temperature (use environment temperature) by about 3 to 10 ℃.

In the present embodiment, even when the temperature of the hair H measured by the hair temperature measuring unit 52 is higher than the second temperature, the notification by the notification unit 51 is stopped (see fig. 21).

The second temperature is preferably set to a temperature not lower than the highest temperature at which the hair H is dried, and may be set in a range of 85 to 95 ℃.

In the present embodiment, the blower 10E further includes a usage environment temperature measurement unit 56 for measuring the temperature of the usage environment.

The calculation unit 53 adjusts the target temperature based on the room temperature (use environment temperature) measured by the room temperature measurement unit (use environment temperature measurement unit) 56.

In this way, the calculation unit 53 can calculate a more appropriate target temperature based on the temperature (room temperature) of the surrounding environment of the blower 10E to be used.

For example, in the case where the temperature of the surrounding environment (room temperature) is significantly low, sometimes the hair H is difficult to warm and the hair H has dried before reaching the target temperature. However, in the present embodiment, as shown in fig. 19, when the temperature of the ambient environment (room temperature) is low, the target temperature becomes low.

Therefore, it is possible to suppress the hair H from drying before the target temperature is reached, and to notify the user U of the state of the hair H more appropriately. As a result, the haircut effect can be further improved.

The first temperature is set to a temperature higher than the room temperature (use environment temperature) measured by the room temperature measuring unit (use environment temperature measuring unit) 56, and the notification by the notification unit 51 is stopped when the temperature of the hair H measured by the hair temperature measuring unit 52 is lower than the first temperature.

This can suppress the recognition of the room temperature (use environment temperature) as the temperature of the hair H, and can further improve the usability of the blower 10E. In addition, the following can be suppressed: although the hair H is already dry, the user U can further dry the already dried hair H by mistaking the room temperature (the use environment temperature) for the temperature of the hair H, and can suppress damage to the hair H. Moreover, the operation of the notification unit 51 can be suppressed when warm air is not directed to the hair H, and energy saving can be achieved.

When the temperature of the hair H measured by the hair temperature measuring unit 52 is higher than the second temperature, the notification by the notification unit 51 is stopped.

In this way, it is possible to suppress the temperature of a high-temperature object such as an incandescent bulb from being recognized as the temperature of the hair H, and the usability of the blower 10E can be further improved. Further, when the hair H is not dry, it is possible to prevent the user U from mistaking the temperature of a high-temperature object such as an incandescent bulb for the temperature of the hair H and stopping the drying of the hair H. Moreover, the operation of the notification unit 51 can be suppressed when warm air is not directed to the hair H, and energy saving can be achieved.

In the present embodiment, both the first temperature and the second temperature are set, but only one of the first temperature and the second temperature may be set, or neither of the first temperature and the second temperature may be set.

In addition, in the

blowers

10, 10A, 10B, 10C, and 10D described in the first to fifth embodiments, at least one of the first temperature and the second temperature may be set.

While the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible.

For example, the features described in the first to sixth embodiments can be combined as appropriate.

Further, the specifications (shape, size, design, etc.) of the blower body, the grip, and other fine parts can be appropriately changed.

As described above, the hair dryer according to the present invention includes: a blower main body having an air blowing flow path formed therein, the air blowing flow path having an intake port and a discharge port; an air supply unit disposed in the air supply flow path; and a heating unit disposed in the air blowing flow path at a position closer to the outlet side than the air blowing unit. In addition, the blower includes: a hair temperature measuring unit for measuring the temperature of the hair; and a notification section for notifying a state of the hair. The notification portion has a light emitter provided around the discharge port.

In this way, the notification portion can be brought into the range of the field of view of the user who is observing the heating portion of the hair, and therefore the user can confirm the state of the hair without moving the line of sight. As a result, the state of the hair can be confirmed more easily.

In this case, the light emitting region of the light-emitting body may be substantially aligned with the measurement region of the hair temperature measurement unit.

In this way, the user can more accurately recognize which part of the hair temperature is being measured, and thus can use the hair dryer more intuitively. As a result, the usability of the hair dryer can be further improved.

Further, a hair dryer according to the present invention includes: a blower main body having an air blowing flow path formed therein, the air blowing flow path having an intake port and a discharge port; an air supply unit disposed in the air supply flow path; and a heating unit disposed in the air blowing flow path at a position closer to the outlet side than the air blowing unit. Further, the apparatus comprises: a hair temperature measuring unit for measuring the temperature of the hair; and a notification section for notifying a state of the hair. The notification unit includes a light emitter provided around the suction port.

In this way, since the notification portion can be reflected on the mirror when the back of the head is dried, the state of the hair can be confirmed more easily.

Further, a hair dryer according to the present invention includes: a blower main body having an air blowing flow path formed therein, the air blowing flow path having an intake port and a discharge port; a holding part which is provided integrally with the blower main body; an air supply unit disposed in the air supply flow path; and a heating unit disposed in the air blowing flow path at a position closer to the outlet side than the air blowing unit. In addition, the blower includes: a hair temperature measuring unit for measuring the temperature of the hair; and a notification section for notifying a state of the hair. The notification unit includes a light emitter provided at the distal end of the grip unit.

The notification unit may have three or more color light emitters.

In this way, the hair can be identified as passing by during drying, and therefore, the convenience of use of the hair dryer can be further improved.

Further, a hair dryer according to the present invention includes: a blower main body having an air blowing flow path formed therein, the air blowing flow path having an intake port and a discharge port; an air supply unit disposed in the air supply flow path; and a heating unit disposed in the air blowing flow path at a position closer to the outlet side than the air blowing unit. Further, the apparatus comprises: a hair temperature measuring unit for measuring the temperature of the hair; and a notification section for notifying a state of the hair. The notification portion is provided separately from the blower main body.

In this way, the notification portion can be provided in a place that is easily visible to the user himself/herself, and thus the usability of the hair dryer can be further improved.

Further, the notification unit may be provided in an information processing terminal separate from the blower main body.

In this way, the state of the hair can be displayed on the screen, and the convenience of use of the hair dryer can be further improved.

The hair dryer according to the present invention further includes a usage environment temperature measuring unit for measuring a temperature of a usage environment, and the notification unit notifies whether or not the temperature of the hair reaches a target temperature. The target temperature may be controlled based on the temperature of the usage environment measured by the usage environment temperature measuring unit.

In this way, the more appropriate target temperature can be calculated by the calculation unit based on the temperature of the environment around the blower used, and therefore the user can be more appropriately notified of the state of the hair. As a result, the haircut effect can be further improved.

In the hair dryer according to the present invention, the first temperature may be set to a temperature higher than the temperature of the usage environment measured by the usage environment temperature measuring unit, and the notification by the notification unit may be stopped when the temperature of the hair measured by the hair temperature measuring unit is lower than the first temperature.

In this way, the temperature of the use environment can be prevented from being recognized as the temperature of the hair, and the usability of the hair dryer can be further improved. In addition, the following can be suppressed: however, the user can consider the temperature of the use environment as the temperature of the hair to further dry the dried hair, thereby suppressing damage to the hair. Further, the operation of the notification unit can be suppressed when warm air is not applied to the hair, and energy can be saved.

In the hair dryer according to the present invention, the notification unit may stop the notification when the temperature of the hair measured by the hair temperature measurement unit is higher than the second temperature.

In this way, it is possible to suppress recognition of the temperature of a high-temperature object such as an incandescent bulb as the temperature of hair, and it is possible to further improve the usability of the hair dryer. Further, when the hair is not dry, it is possible to prevent the user from mistaking the temperature of a high-temperature object such as an incandescent bulb for the temperature of the hair and stopping the drying of the hair. Further, the operation of the notification unit can be suppressed when warm air is not applied to the hair, and energy can be saved.
