Description

Technical Field

[0001] The present invention relates to a hair dryer and a hair drying system. Background Art

[0002] A general hair dryer can blow warm air or cold air according to its use.

[0003] For example, Japanese Patent Application Laid-Open No. 2005-547 discloses a hair dryer that thermally isolates adjacent flow paths, enables the temperature of the air flowing in each flow path to be an appropriate temperature, and can efficiently prevent hair deformation, hair drying caused by warm air, hair fixation, and over-drying caused by cold air. Summary of the Invention

[0004] The hair dryer 1 described in Japanese Patent Application Laid-Open No. 2005-547 has a plurality of flow paths 2 and 3 through which air of different temperatures flows, and a blowing mechanism that simultaneously discharges the air flowing in each of the flow paths 2 and 3 to the hair. Further, the warm air discharged from the discharge portion of one flow path 2, that is, the warm air, is brought into contact with the cold air discharged from the discharge portion of the other flow path 3, that is, the above-mentioned warm air, so that the warm air first contacts the desired portion of the hair to deform and dry the hair, and then the hair dryer 1 is moved (or the orientation is changed) so that the cold air contacts the portion of the hair that has been contacted by the warm air to try to prevent over-drying of the hair.

[0005] However, in this method, since the cold air and the warm air are blown out simultaneously, the warm air blows to the portion adjacent to the portion where the cold air blows, and the entire hair cannot be cooled. In addition, when a person (user) uses a hair dryer for the purpose of drying wet hair, it is inclined to blow high-temperature and high-volume air to the hair so that the hair can be dried in a shorter time. When drying the hair in this way, after drying (after using the hair dryer), the hair is maintained in a relatively high temperature state (that is, a state where water easily evaporates) for a long time, and the hair may become in an over-dried state.

[0006] An object of the present invention is to provide a hair dryer and a hair drying system completed in view of the above situation.

[0007] A hair dryer according to an aspect of the present invention has a hair drying mode and a completion mode that is performed after the hair drying mode as operation modes. The hair dryer includes: a temperature sensor that measures the temperature of an object to which the hair dryer is used; and a notification unit that notifies a user of this situation when the measured temperature of the temperature sensor becomes equal to or lower than a specified value after switching from the hair drying mode to the completion mode.

[0008] On the other hand, the hair drying system of the present invention includes: a hair dryer equipped with a temperature sensor for measuring the temperature of an object to be measured, the hair dryer including hair drying mode and a completion mode that follows the hair drying mode as operation modes; and an information terminal capable of communicating with the hair dryer. The information terminal has a notification unit, and after the operation mode of the hair dryer switches from the hair drying mode to the completion mode, when the measured temperature of the temperature sensor becomes equal to or lower than a specified value, the notification unit notifies this situation to the user.

[0009] According to one aspect of the present invention, a hair dryer or a hair drying system capable of more appropriately suppressing over-drying of hair can be provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same reference numerals are given to the same components. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated.

[0012] <First Embodiment> In the present embodiment, the hair dryer 10, which is an example of the hair dryer of the present invention, will be described as an example. The hair dryer 10 can be used for the purpose of drying hair or styling hair.

[0013] (Configuration of the hair dryer) First, the configuration of the hair dryer 10 of this embodiment will be described. Figure 1 Shows the appearance of the hair dryer 10. Figure 2 Shows the internal configuration of the hair dryer 10.

[0014] The outer shape of the hair dryer 10 is mainly composed of the main body 11. The main body 11 has a front part 11a, side parts 11b, a back part, etc. An air outlet 15 is provided in the front part 11a.

[0015] The main body 11 is provided with an electric blower 12, a heater 13, a temperature sensor 21, a three-dimensional sensor 22, an operation unit 31, a speaker 32, a control unit 40, etc.

[0016] The electric blower 12 includes a fan and a drive motor, and the fan is connected to the drive motor. When the hair dryer 10 is operating, the fan is rotated by the driving force of the drive motor. Thereby, an air flow toward the air outlet 15 is formed inside the hair dryer 10. The electric blower 12 starts or stops operating (rotating) based on an instruction from the control unit 40. In addition, the electric blower 12 changes the rotation speed of the fan based on an instruction from the control unit 40.

[0017] The heater 13 heats the air taken into the main body 11 from an air intake (not shown). When the hair dryer 10 is operating, the air introduced into the hair dryer 10 is heated by the operation of the heater 13, and warm air can be sent out from the air outlet 15. The heater 13 controls the on / off of heating based on an instruction from the operation control unit 42 in the control unit 40.

[0018] The temperature sensor 21 is arranged, for example, in the front part 11a of the main body 11 (refer to Figure 1 ). The temperature sensor 21 measures the temperature of an object (such as the user's hair, etc.) using the hair dryer 10. The temperature sensor 21 is preferably a temperature sensor capable of measuring the temperatures of multiple parts simultaneously. By adopting such a temperature sensor 21, for example, the temperature of the object to be measured such as the user's hair can be detected in a wider range. As such a temperature sensor 21, for example, an infrared array sensor, an infrared thermal imager, etc. can be cited. The temperature information measured by the temperature sensor 21 is sent to the control unit 40. This temperature information is stored in the memory 51 in the control unit 40.

[0019] The three-dimensional sensor 22 is arranged, for example, in the front part 11a of the main body 11 (refer to Figure 1)。The three-dimensional sensor 22 is a sensor that grasps the spatial position (three-dimensional position) of the hair dryer 10. Examples of the three-dimensional sensor 22 include a 3D acceleration sensor, a gyro sensor, a geomagnetic sensor, etc. The three-dimensional position information measured by the three-dimensional sensor 22 is sent to the control unit 40. This three-dimensional position information is stored in the memory 51 within the control unit 40. The three-dimensional sensor 22 may also be provided within the gripping portion.

[0020] The operation unit 31 is provided, for example, on the front surface portion 11a of the main body portion 11. The operation unit 31 includes, for example, a power switch, operation switching buttons (air volume switching button, air temperature switching button), etc. The operation unit 31 is operated by the user, and this operation information is sent to the control unit 40.

[0021] When using the hair dryer 10, by the user operating the operation unit 31, the hair dryer 10 starts or stops operating. Additionally, by operating the operation unit 31, the type (warm air / cold air) and volume of the air blown out from the air outlet 15 are adjusted. Further, by the operation unit 31, the operation mode of the hair dryer 10 is switched.

[0022] Based on an instruction sent from the control unit 40, the speaker 32 emits various notification sounds or voice messages, etc. to the user. The speaker 32 is an example of a notification unit that notifies the user when the measured temperature of the temperature sensor becomes below a specified value after switching from the hair drying mode to the completion mode.

[0023] In addition, as other examples of the notification unit, a display unit (not shown) that displays the current operation mode of the hair dryer 10, etc. may be cited. For example, the color of the display lamp (e.g., LED) included in the display unit may also be changed, and when the measured temperature of the temperature sensor becomes below a specified value after switching from the hair drying mode to the completion mode, the user is notified of this situation.

[0024] The control unit 40 is connected to each component within the hair dryer 10 and controls them. The control unit 40 includes a memory 51, a timer 52, a drying determination unit 41, an operation control unit 42, etc. The control unit 40 controls the operations of the electric blower 12, the heater 13, the speaker 32, etc. according to the content operated by the operation unit 31, the detection results of various sensors, etc.

[0025] After the control unit 40 switches from the hair drying mode to the completion mode, when the measured temperature of the temperature sensor 21 becomes equal to or lower than a specified value, the operation of the electric blower 12 is stopped. As a result, the air supply from the hair dryer 10 stops. The user of the hair dryer 10 can recognize that the temperature of the hair measured by the temperature sensor 21 has become equal to or lower than the specified value through the stop of the air supply from the hair dryer 10. The stop of the air supply from the hair dryer 10 is equivalent to a notification to the user. Therefore, the control unit 40 is an example of a notification unit that notifies the user of this situation when the measured temperature of the temperature sensor becomes equal to or lower than the specified value after switching from the hair drying mode to the completion mode.

[0026] The memory 51 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The memory 51 stores the operation program and setting data of the hair dryer 10, and temporarily stores the calculation results of the control unit 40 and the like. In addition, the memory 51 stores the detection results of the temperature sensor 21 and the three-dimensional sensor 22. The timer 52 measures, as needed, the time of processing performed in the control unit 40, the operation time of each component in the hair dryer 10, and the like.

[0027] The drying determination unit 41 determines the drying state (degree of drying) of the object to be used by the hair dryer 10. The drying determination unit 41 determines the drying state of the object based on, for example, the temperature, moisture content, humidity, conductivity, etc. of the object. In one example, the drying determination unit 41 determines the drying state of the object based on the measurement results of the temperature sensor 21 and the three-dimensional sensor 22.

[0028] The operation control unit 42 switches the operation mode of the hair dryer 10 based on an instruction from the operation unit 31, information from various sensors (for example, the temperature sensor 21 and the three-dimensional sensor 22), and the drying determination unit 41. In one example, the operation control unit 42 switches from the "hair drying mode" to the "completion mode" based on the determination result of the drying determination unit 41.

[0029] In addition to the above configuration, the hair dryer 10 may further include an ion generator (not shown) and a distance sensor (not shown).

[0030] The ion generator 50 generates at least one of positive (+) ions (for example, H + (H2O)m (m is an arbitrary natural number)) and negative (-) ions (for example, O 2 - (H 2 O)n (n is an arbitrary natural number)). By having an ion generator, the hair dryer 10 can make the blown air contain ions.

[0031] The ion generator is an example of a charged particle supply (generation) mechanism. Additionally, the charged particle supply (generation) mechanism is a mechanism that supplies (generates) charged particles.

[0032] Charged particles refer to electrically neutral particles and active species activated in an electrically neutral state. Charged particles are not limited to particles with electric charges. For example, they also include particles such as atoms and molecules that do not have electric charges but have unpaired electrons. Specifically, charged particles include, for example, ions with positive or negative charges, ion complexes with positive or negative charges, free radicals, electrons, cations, etc.

[0033] The charged particle supply (generation) mechanism can, for example, be a mechanism that only supplies (generates) one type of charged particle, or it can be a mechanism that supplies (generates) multiple types of charged particles. The charged particle supply (generation) mechanism can, for example, supply (generate) both positive ions or ion complexes of positive ions (for example, complexes in which polar molecules such as water molecules are coordinated to positive ions) and negative ions or ion complexes of negative ions (for example, complexes in which polar molecules such as water molecules are coordinated to negative ions). The charged particle supply (generation) mechanism can, for example, only supply (generate) one of the positive and negative ion complexes.

[0034] The distance sensor measures, for example, the distance between the hair dryer 10 and the user. As the distance sensor, for example, a ToF (Time of Flight) type ranging sensor that measures the above distance based on the reflection time of infrared light from a specific part of the user's hair to the distance sensor can be cited. Additionally, instead of the distance sensor, for example, GPS, a reflection Doppler sensor, a camera, and a dot projector can be used to measure the distance between the hair dryer 10 and the user.

[0035] (Operation of the hair dryer) Next, the operation of the hair dryer 10 will be described. The hair dryer 10 of the present embodiment can operate in multiple operation modes. The user can select a specified operation mode by operating the operation unit 31, and can make the air volume, temperature, etc. sent out from the air outlet 15 different. For example, when using the hair dryer 10 for the purpose of styling hair, the styling mode is selected. Additionally, when using the hair dryer 10 for the purpose of drying hair, the hair dryer mode is selected.

[0036] And, when the hair dryer mode is selected in the hair dryer 10, for the purpose of making the completion state of the hair to be dried better, the hair dryer 10 is set to automatically (for example, based on an instruction from the control unit 40) change from the "hair drying mode" to the "completion mode". In addition, in other embodiments, the switching from the "hair drying mode" to the "completion mode" can also be manually performed by the user operating the operation unit 31.

[0037] Here, the "hair drying mode" is an operation mode set mainly for the purpose of drying wet hair in a shorter time. In the state where the "hair drying mode" is selected, the heater 13 is turned on, and the rotation speed of the electric blower 12 increases compared to the "completion mode". Thereby, air (i.e., high-speed warm air) with a larger volume is sent out from the air outlet 15 at a higher temperature than in the "completion mode". It should be noted that the "hair drying mode" can also be described as the "warm air mode", the "high-speed warm air mode", etc.

[0038] In addition, the "completion mode" is an operation mode executed in the completion stage of hair drying after the above-mentioned "hair drying mode". This "completion mode" is an operation mode built into the hair dryer 10 to achieve a good completion state when drying wet hair. By setting such a "completion mode", it is possible to cool the hair that has the heat brought by the warm air during drying, prevent over-drying of the hair, or tighten the cutin layer of the hair.

[0039] In this way, the hair dryer 10 of this embodiment has a "hair drying mode" and a "completion mode" that follows the "hair drying mode". In one example, in the operation mode (such as the hair dryer mode) used for the purpose of drying hair, it includes the "hair drying mode" and the "completion mode". Then, when the user selects the hair dryer mode, the "hair drying mode" is first executed. After that, when the specified conditions are met, the operation mode of the hair dryer 10 changes from the "hair drying mode" to the "completion mode".

[0040] In the state where the "completion mode" is selected, the heater 13 is turned off, and the rotation speed of the fan of the electric blower 12 is lower than that in the "hair drying mode". Thereby, air with a small volume (i.e., low-speed cold air) is sent out from the air outlet 15 at a temperature lower than that in the "hair drying mode". In addition, the "completion mode" can also be described as the "cold air mode", the "low-speed cold air mode", etc.

[0041] For example, based on the judgment result of the drying judgment unit 41, the mode change from the "hair drying mode" to the "completion mode" can be performed. More specifically, the drying judgment unit 41 determines the drying state of the object based on the measurement results of the temperature sensor 21 and the three-dimensional sensor 22. In addition, in the configuration where the hair dryer 10 has a component (such as a moisture sensor, etc.) capable of measuring the moisture content (or humidity) of the hair, the drying judgment unit 41 can also determine the drying state of the object based on the moisture content, humidity, etc. of the object.

[0042] Then, if the drying judgment unit 41 determines that the object has become a state where it should be transferred to the completion mode, accepting this judgment result, the operation control unit 42 performs the switching of the operation mode from the "hair drying mode" to the "completion mode".

[0043] As a result, the final state of the hair to be dried can be made better.

[0044] In addition, generally, when a person (user) uses a hair dryer to dry wet hair, there is a tendency to direct a high-temperature and high-volume airflow at the hair to dry the hair in a shorter time. Then, after the person (user) determines that the hair to be dried has reached a dry state, the operation of the hair dryer 10 is stopped. Or, in order to cool the hair that has reached a high temperature state, the airflow of the hair dryer 10 is switched from warm air to cold air. However, if a person determines the dry state of the hair and stops the operation (or switching operation) of the hair dryer 10, due to the influence of the heat accumulated in the hair, the hair will continue to dry further after the operation stops, and there is a possibility that the hair will become over-dried.

[0045] Therefore, in the hair dryer 10 according to the present embodiment, in order to more reliably suppress over-drying of the hair, after the operation mode of the hair dryer 10 is switched from the "hair drying mode" to the "completion mode", the temperature sensor 21 measures the temperature of the hair to be dried. Then, when the measured temperature of the temperature sensor 21 becomes equal to or lower than a predetermined value, it is set to notify the user of this situation.

[0046] As a method of notifying the user, methods such as notifying the user by stopping the air supply of the hair dryer, or making a sound from the speaker 32, or stopping the air supply and making a sound can be cited.

[0047] In addition, when the temperature sensor 21 can measure the temperatures at multiple positions simultaneously and detect the temperature of the object to be measured in a larger range, it is preferably set to notify the user when the maximum temperature among the measured values in a specified range obtained becomes equal to or lower than a predetermined value. Thereby, it is possible to avoid stopping the air supply of the hair dryer in a state where a part of the hair is not sufficiently cooled.

[0048] In Figure 3 shows the operation flow in the case of using the hair dryer 10 in the dryer mode. Figure 4 is a diagram showing an example of an image of the temperature measurement result stored in the memory 51 in the control unit 40 during the use of the hair dryer 10.

[0049] When the user selects a hair dryer mode by operating the operation unit 31 (step S11), the control unit 40 in the hair dryer 10 first starts the operation in the "hair drying mode" (step S12). Specifically, the operation control unit 42 in the control unit 40 controls the fan speed of the electric blower 12, the set temperature of the heater 13, etc. based on the operation conditions at the time of setting the "hair drying mode" stored in the memory 51.

[0050] If the hair dryer 10 starts the operation in the "hair drying mode", the drying determination unit 41 in the control unit 40 starts to determine the drying state of the object to be dried (for example, the user's hair) (step S13).

[0051] The drying determination unit 41 determines the drying state of the object based on the measurement results of the temperature sensor 21, the three-dimensional sensor 22, etc. In the method for determining the drying state here, for example, the methods described in Japanese Unexamined Patent Application Publication No. 2021-19835 and Japanese Unexamined Patent Application Publication No. 2021-19837 can be used, but other known methods can also be used.

[0052] The drying determination unit 41 determines the drying state of the object. When it is determined that the transfer from the "hair drying mode" to the "completion mode" should not be made yet (when the result in step S14 is "no"), the operation in the "hair drying mode" continues.

[0053] On the other hand, when the drying determination unit 41 determines the drying state of the object and determines that the transfer from the "hair drying mode" to the "completion mode" should be made (when the result in step S14 is "yes"), the transfer from the "hair drying mode" to the "completion mode" is made (step S15). Specifically, the operation control unit 42 controls the fan speed of the electric blower 12, the operation (or set temperature) of the heater 13, etc. based on the operation conditions at the time of setting the "completion mode" stored in the memory 51.

[0054] If the hair dryer 10 starts the operation in the "completion mode", the control unit 40 measures the temperature of the object using the temperature sensor 21 (more specifically, the array sensor). At the same time, the control unit 40 measures the three-dimensional position of the object at the time of temperature measurement using the three-dimensional sensor 22.

[0055] The temperature information of the temperature sensor 21 (more specifically, the measurement value of the array sensor) and the position information of the three-dimensional sensor 22 are associated with each other and stored in the memory 51 in the control unit 40.

[0056] In Figure 4 shows an image of the temperature information T of the hair H obtained as a result of the hair dryer 10 measuring the temperature and position of the hair H as the object to be dried. The temperature information T is formed as image information in the hair dryer 10, for example, according to the temperature information and position information stored in the memory 51. In addition, when the hair dryer 10 can communicate with an external information terminal (for example, a smartphone, a tablet terminal, etc.), the temperature information T is displayed on the display unit of the external information terminal. Also, in Figure 4 the image of the temperature information T is displayed in a state of viewing the user from the front, but the image of the temperature information T also includes the image when viewing the user from the back side and can be freely switched and confirmed.

[0057] When the operation control unit 42 refers to the temperature information T and the measured temperature is higher than the specified value (when it is "No" in step S16), the operation in the "completion mode" continues. The case where the measured temperature is higher than the specified value means, for example, that the maximum temperature among the respective temperatures in the measurement area is higher than the specified value.

[0058] On the other hand, when referring to the temperature information T and the measured temperature becomes equal to or lower than the specified value (when it is "Yes" in step S16), the operation control unit 42 stops the operations of the electric blower 12 etc. and reports to the user the end of the completion mode (step S17). In addition, when other components such as the heater 13 and the ion generator are operating, the operations of these components also stop.

[0059] Furthermore, the control unit 40 uses the speaker 32 to report to the user the end of the completion mode (step S18). Then, the operation of the blower mode of the hair dryer 10 ends.

[0060] (Summary of the First Embodiment) The hair dryer 10 of the present embodiment has a hair drying mode and a completion mode performed after the hair drying mode as operation modes. The hair dryer 10 includes a temperature sensor 21 that measures the temperature of an object (object to be dried) using the hair dryer, and a notification unit that notifies the user of certain information. After the operation mode of the hair dryer switches from the hair drying mode to the completion mode, when the measured temperature of the temperature sensor 21 becomes equal to or lower than the specified value, the notification unit notifies the user of this situation.

[0061] For example, in the present embodiment, the control unit 40, the speaker 32, etc. function as the notification unit. After switching from the hair drying mode to the completion mode, when the measured temperature of the temperature sensor 21 becomes equal to or lower than the specified value, the control unit 40 stops the operation of the electric blower 12. As a result, the air supply from the hair dryer 10 stops. The user of the hair dryer 10 can recognize that the temperature of the hair measured by the temperature sensor 21 has become equal to or lower than the specified value through the stop of the air supply from the hair dryer 10. The stop of the air supply from the hair dryer 10 is equivalent to the notification to the user.

[0062] After switching from the hair drying mode to the completion mode, when the measured temperature of the temperature sensor becomes equal to or lower than the specified value, the speaker 32 issues a voice message etc. of this situation and notifies the user.

[0063] According to the above configuration, it is not the person using the hair dryer who judges the drying state of the hair by himself / herself, but the timing to end the completion mode can be determined based on the temperature measurement result of the object to be dried by the temperature sensor 21. Thus, over-drying of the hair caused when a person judges the hair drying state can be suppressed, and the completion state of the hair can be made better.

[0064] <Second Embodiment> Next, the second embodiment will be described. In the above-described embodiment, an example was given of the configuration in which the hair dryer 10 has the three-dimensional sensor 22 that grasps its own spatial position (three-dimensional position). However, the hair dryer according to another embodiment may not have a three-dimensional sensor.

[0065] In addition, in the first embodiment, an example was given of the hair dryer 10 having both the control unit 40 and the speaker 32 as functions of the notification unit. However, in other embodiments, only the control unit 40 may function as the notification unit.

[0066] Therefore, in the second embodiment, an example of a hair dryer that does not have a three-dimensional sensor and a speaker will be described. Figure 5 Fig. shows the internal structure of the hair dryer 110 according to the second embodiment. As Figure 5 shown, the hair dryer 110 does not have a three-dimensional sensor and a speaker. This is different from the hair dryer 10 according to the first embodiment. In the hair dryer 110, the other configurations may be the same as those in the first embodiment.

[0067] As the temperature sensor 21, a temperature sensor that can measure the temperatures at multiple positions simultaneously is used. As such a temperature sensor 21, for example, an infrared array sensor, an infrared thermal imager, etc. can be cited. The temperature information measured by the temperature sensor 21 is sent to the control unit 40. This temperature information is stored in the memory 51 within the control unit 40.

[0068] For example, when the user uses the hair dryer 110 in a state where the hair dryer mode is selected, the user moves the hair dryer 110 around the hair that is the object to be dried while blowing air over the entire hair. At this time, the temperature sensor 21 of the hair dryer 110 measures the temperatures of various parts of the object to be dried at multiple points simultaneously according to the operation of the hair dryer 110. Then, the temperature information measured by the temperature sensor 21 is stored in the memory 51 at any time.

[0069] The control unit 40 can obtain the temperature information T of the entire object to be dried (for example, hair) from the multiple temperature information stored in the memory 51 at any time (refer to Figure 4 ). The hair dryer 110 refers to this temperature information T and determines whether the measured temperature of the object to be dried has reached below a specified value after the operation mode is switched from the "hair drying mode" to the "completion mode".

[0070] Then, when the measured temperature of the object to be dried becomes below the specified value, the operation control unit 42 notifies the user of this situation by stopping the operation of the electric blower 12 or the like. Thereby, over-drying of the hair can be more reliably suppressed.

[0071] <Third Embodiment> In the third embodiment, one embodiment of the hair drying system will be described. Figure 6 The overall configuration of the hair drying system 1 of this embodiment is shown. The hair drying system 1 includes a hair dryer 210 and an information terminal 220 that can communicate with the hair dryer 210. Figure 6 Although not shown, the hair drying system 1 may also have a server between the hair dryer 210 and the information terminal 220. The server controls the communication between the hair dryer 210 and the information terminal 220.

[0072] Figure 7 The internal configuration of the hair dryer 210 is shown. Figure 8 The internal structure of the information terminal 220 is shown. The information terminal 220 is, for example, a smartphone, a tablet terminal, a personal computer, a wearable terminal, etc. The hair dryer 210 and the information terminal 220 can communicate via Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), a carrier network, the Internet, a router, etc.

[0073] The hair dryer 210 includes a temperature sensor 21 that measures the temperature of the object to be measured, and a hair dryer mode that includes a hair drying mode and a completion mode that is performed after the hair drying mode. As Figure 7 shown, in addition to the temperature sensor 21, the hair dryer 210 also includes an electric blower 12, a heater 13, a three-dimensional sensor 22, an operation unit 31, a speaker 32, a communication interface 233, a control unit 40, etc. Except for the communication interface 233, the same configuration as the hair dryer 10 described in the first embodiment can be applied. In addition, the hair dryer 210 may also have the same configuration as the hair dryer 110 described in the second embodiment.

[0074] The communication interface 233 is implemented by an antenna or a connector. The communication interface 233 exchanges data with other devices through wired communication or wireless communication. Specifically, the communication interface 233 sends temperature information T generated in the hair dryer 210 to an external terminal (for example, the information terminal 220, etc.).

[0075] As Figure 8 shown, the information terminal 220 includes a display unit 251, an operation unit 252, a speaker 253, a communication interface 254, a control unit 260, etc.

[0076] The display unit 251 includes a liquid crystal display panel, LED lights, etc. The display unit 251 outputs a screen such as text or an image according to a signal from the control unit 260. The operation unit 252 receives an instruction from the user and inputs the instruction into the control unit 260. In addition, in the present embodiment, the information terminal 220 has a touch panel formed by combining the display unit 251 and the operation unit 252.

[0077] Based on an instruction from the control unit 260, the speaker 253 emits various notification sounds or voice messages and other sounds to the user.

[0078] The communication interface 254 is implemented through an antenna or a connector. The communication interface 254 exchanges data with other devices through wired communication or wireless communication. Specifically, the communication interface 254 receives the temperature information T and the like sent from the hair dryer 210.

[0079] The control unit 260 is connected to each component in the information terminal 220 and controls them. The control unit 260 includes a memory 261, a timer 262, etc. For example, the same temperature information as the temperature information T stored in the memory 51 of the hair dryer 210 is stored in the memory 261.

[0080] In the present embodiment, the temperature information T sent from the hair dryer 210 is displayed on the display unit 251. Then, after the operation mode of the hair dryer 210 is switched from the hair drying mode to the completion mode and the measured temperature of the temperature sensor 21 becomes below a specified value, the display unit 251 performs a display to notify the user of this situation. In this way, the display unit 251 is an example of a notification unit.

[0081] In addition to the display unit 251, the control unit 260 can also use the speaker 253 to notify the user of this situation. In this way, the speaker 253 is an example of a notification unit.

[0082] As a result of measuring the temperature and position of the hair H as the object to be dried, the obtained temperature information T of the hair H is stored in the memory 261 in the information terminal 220 via the communication interface 233 and the communication interface 254. The control unit 220 of the information terminal 220 forms image information according to the temperature information stored in the memory 261 and displays an image reflecting the temperature information T on the display unit 251 (refer to Figure 6 ). In addition, in Figure 6 , the image of the temperature information T is displayed in a state of viewing the user from the front, but the temperature information T also includes an image when viewing the user from the back side and can be freely switched and confirmed.

[0083] In the display unit 251, for example, the temperature of the hair H to be dried is displayed in various colors. By recognizing the colors of the image displayed on the display unit 251, the user can confirm the temperature of the hair. Moreover, when the temperature of the hair becomes higher than required, over-drying of the hair can be more reliably suppressed by stopping the operation of the hair dryer 210 or reducing the heater temperature, etc.

[0084] It should be understood that the embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the present invention is represented not by the above description but by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In addition, the configurations obtained by combining the configurations of different embodiments described in this specification are also included in the scope of the present invention.
