[0002] In recent years, there has been known clothing equipped with a fan device that blows out air to lower the user's body temperature through the heat of vaporization, and which allows the fan device to be switched between multiple operating modes, making it easier to adjust the temperature by changing the amount of airflow.

[0019] The present invention will be described in detail below with reference to the drawings. However, the embodiments described below are subject to various technically preferable limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0020] [Overall configuration] As shown in FIG. 1, the fan unit-equipped wear 100 of the first embodiment comprises a wear body 1 and a fan unit 2 having a fan 21 that introduces air into the wear body 1. The outside air taken into the wear body 1 by the fan unit 2 is circulated along the surface of the user's body or underwear and then discharged from the collar and sleeves of the wear body 1, thereby evaporating sweat from the body and cooling the body by the latent heat of vaporization.

[0021] [Clothing] As shown in FIG. 1, the garment body 1 is, for example, a blouson type garment, and includes an opening / closing means 11 for opening and closing the front of the garment body 1, an air leakage prevention means 12 for preventing air from leaking from the hem of the garment body 1 between the garment body 1 and the user, a fan mounting hole 13 for removably mounting a fan 21 (described later), a battery holding means 14 for holding a battery 222 (described later), and a cable holding means 15 for holding a cable C connecting the fan 21 and the battery 222. The garment body 1 need only be formed from a sheet-like material that is either non-breathable or has sufficient breathability to allow it to be inflated by the introduction of outside air by the fan device 2, so that the fan device 2 can be attached; other configurations are optional.

[0022] [Fan device] As shown in Figures 2 and 3, the fan device 2 includes a fan 21 that takes in outside air into the inside of the garment body 1, a drive unit 22 that drives the fan 21, an operation unit 23 that inputs a signal to switch the drive state of the drive unit 22, a control unit 24 that receives a signal from the operation unit 23 and controls switching the drive state of the drive unit 22, a display unit 25 that displays the drive state of the drive unit 22, and an I / F (Interface) 26 for connecting to the fan 21 via a cable C or the like and for connecting to an external power source.

[0023] [fan] The fan 21 has, for example, a propeller (not shown) housed inside a case body, and is detachably attached to the fan attachment hole 13. The fan 21 may have any specific configuration as long as it can take in outside air into the wear body 1. Although Fig. 1 shows a configuration in which two fans 21 are provided for one fan device 2, the present invention is not limited to this, and a configuration in which only one fan is provided as shown in Fig. 2, or a configuration in which more than two fans are provided, may also be used.

[0024] [Drive unit] The drive unit 22 is a member that drives the fan 21, and includes, for example, a motor 221, a transmission mechanism (not shown) for transmitting the rotational force of the motor 221 to the propeller, and a battery 222 that applies the voltage required to drive the motor 221.

[0025] [Operation section] The operation unit 23 is, for example, a switch provided on the outer surface of the drive unit 22 , and includes a first changeover switch 231 and a second changeover switch 232 .

[0026] (First changeover switch) The first changeover switch 231 is a switch for switching the mode (described later) of the drive unit 22, and is also a power switch for switching the drive unit 22 ON / OFF.

[0027] Specifically, when the user presses the first changeover switch 231 for less than a predetermined second (for example, 2 seconds), it switches the mode of the drive unit 22. Also, when the power switch 231 is pressed for a predetermined second or longer, it switches ON / OFF of the drive unit 22. In the following, a switch operation for switching the mode of the drive unit 22 is referred to as a "short press", and a switch operation for switching the first changeover switch 231 between ON / OFF of the drive unit 22 is referred to as a "long press".

[0028] (Second changeover switch) The second changeover switch 232 is a switch that changes the mode of the drive unit 22 to a first mode (described later).

[0029] When the second changeover switch 232 is pressed, if the drive unit 22 is ON, the remaining charge of the battery 222 is equal to or greater than a predetermined charge (e.g., 60% or more), and a predetermined time (e.g., 30 minutes) has elapsed since the last time the first mode was switched to the second mode, then the mode is switched to the first mode. When the drive unit 22 is in the OFF state, or when the second changeover switch 232 is pressed while the fan device 2 is already in the first mode, the drive unit 22 is not turned ON / OFF and the mode is not switched.

[0030] [Control Unit] The control unit 24 is composed of a CPU (Central Processing Unit), a RAM (Random Access Memory) including a non-volatile memory, a ROM (Read Only Memory) in which a determination program, setting data, etc. are stored, and a timer, etc., and performs central control of each part of the fan device 2.

[0031] Specifically, the control unit 24 switches the driving state of the driving unit 22 and the display on the display unit 25 according to the current driving state of the driving unit 22 and a signal input from the operation unit 23. Furthermore, when the driving unit 22 is automatically switched from the first mode to the second mode, the control unit 24 starts counting a timer from that point on, and sets a standby time elapsed flag after a predetermined time (e.g., 30 minutes) has elapsed. Note that the timer continues to count even when the driving unit 22 is in the OFF state.

[0032] [Display] The display unit 25 is, for example, a seven-segment display, and displays numbers or letters according to the mode of the drive unit 22, thereby allowing the user of the garment body 1 to recognize the current mode.

[0033] [Interface] The I / F 26 has connection terminals for connecting to various peripheral devices, a communication unit for transmitting and receiving signals to and from external devices, etc. In this embodiment, the I / F 26 is, for example, a DC (Direct Current) plug provided on the case body, and by connecting to a commercial power outlet via an AC (Alternating Current) adapter, the AC power source power is converted into a DC power source voltage, and the battery 222 is charged. Also, the I / F 26 in this embodiment is a connection terminal, and by connecting the motor 221 and the battery 222 via a cable C, the voltage of the battery 222 is applied to the motor 221.

[0034] [Modes and switching between them] The drive unit 22 of the fan device 2 according to the first embodiment has five modes, namely, first to fifth modes, which are set so as to achieve the voltage applied to the motor 221 and the air volume of the fan 21 shown in FIG.

[0035] As shown in FIG. 4, in this embodiment, the voltage applied to the motor 221 and the airflow of the fan 21 are set to be the largest in the first mode, and then to be smaller in the fifth mode. However, the voltage applied and the airflow of each mode are set to be the largest in the first mode, and the largest in the fifth mode. It is sufficient that the values ​​are large and different for each mode, and are not limited to the values ​​shown in FIG.

[0036] When a signal indicating that the first changeover switch 231 is pressed long is inputted to the control unit 24 to turn the drive unit 22 ON, the control unit 24 drives the drive unit 22 in the third mode, and cyclically switches the mode between the fourth mode, the fifth mode, the third mode, and so on, each time a signal indicating that the first changeover switch 231 is pressed short is inputted. In addition, when a signal indicating that the user has pressed the second changeover switch 232 is inputted and a predetermined period (e.g., 5 minutes) has elapsed since the control unit 24 caused the drive unit 22 to drive in the first mode, the control unit 24 automatically switches the mode to the second mode and drives the drive unit 22. In addition, when a signal indicating that the user has pressed the first changeover switch 231 short is inputted while the control unit 24 is in the first mode or the second mode, the control unit 24 switches the mode of the drive unit 22 to the third mode.

[0037] [Flow of driving state change when the first changeover switch is pressed] FIG. 5 is a flowchart showing the above-mentioned mode switching in the fan device 2 according to the first embodiment. First, when a signal indicating that the user has pressed and held down the first changeover switch 231 is input (step S101), the control unit 24 receives the signal and switches the driving unit 22 to the ON state, causing it to operate in the third mode (step S102).

[0038] Next, the control unit 24 determines whether a signal indicating that the first changeover switch 231 is pressed has been input (step S103). If no signal has been input (step S103; No), the control unit 24 continues driving in the third mode until a signal is input.

[0039] If a signal is input (step S103; Yes), the control unit 24 determines whether the signal is due to a short press (step S104). If the signal is not due to a short press (i.e., if the signal is due to a long press) (step S104; No), the control unit 24 turns off the drive unit 22 and ends the drive.

[0040] If the signal is due to a short press (step S104; Yes), the control unit 24 switches the mode of the driving unit 22 to the fourth mode (step S105).

[0041] Next, the control unit 24 determines whether a signal indicating that the first changeover switch 231 is pressed has been input (step S106). If no signal has been input (step S106; No), the control unit 24 continues driving in the fourth mode until a signal is input.

[0042] If a signal is input (step S106; Yes), the control unit 24 determines whether the signal is due to a short press (step S107). If the signal is not due to a short press (i.e., if the signal is due to a long press) (step S107; No), the control unit 24 turns off the drive unit 22 and ends the drive.

[0043] If the signal is due to a short press (Step S107; Yes), the control unit 24 switches the mode of the drive unit 22 to the fifth mode (Step S108).

[0044] Next, the control unit 24 determines whether a signal indicating that the first changeover switch 231 is pressed has been input (step S108). If no signal has been input (step S108; No), the control unit 24 continues driving in the fifth mode until a signal is input from the first changeover switch 231.

[0045] If a signal is input (step S108; Yes), the control unit 24 judges whether the signal is due to a short press (step S109). That is, if the signal is due to a long press (step S110; No), the control unit 24 turns off the drive unit 22 to end the drive.

[0046] If the signal is due to a short press (step S109; Yes), the control unit 24 switches the mode of the driving unit 22 to the third mode (step S102).

[0047] As described above, in the fan device 2 of this embodiment, each time the user presses the first changeover switch 231 to input a signal, the control unit 24 determines whether the signal is due to a short press or a long press, and if it is due to a long press, turns the drive unit 22 to the OFF state and ends the drive, and if it is due to a short press, switches the mode of the drive unit 22 cyclically between the third mode, fourth mode, fifth mode, third mode, ....

[0048] [Flow of driving state change when the second changeover switch is pressed] Next, a flow chart when the second changeover switch 232 is pressed is shown in FIG. First, when a signal indicating that the user has pressed the second changeover switch 232 is input (step S201), the control unit 24 determines whether the driving unit 22 is in the ON state (step S202). If the driving unit 22 is not in the ON state (i.e., if the driving unit 22 is in the OFF state) (step S202; No), the control unit 24 disables the input of the signal (step S206).

[0049] If the driving unit 22 is in the ON state (step S202; Yes), the control unit 24 determines whether the driving unit 22 is in the first mode (step S203). If the driving unit 22 is being driven in the first mode (step S203; Yes), the control unit 24 invalidates the input of the signal and displays an error on the display unit 25 (step S206).

[0050] If the driving unit 22 is not in the first mode (step S203; No), the control unit 24 determines whether the remaining charge of the battery 222 of the driving unit 22 is equal to or greater than a predetermined remaining charge (step S204). If the remaining charge of the battery 222 is not equal to or greater than the predetermined remaining charge (step S204; No), the control unit 24 invalidates the input of the signal and displays an error on the display unit 25 (step S206).

[0051] If the remaining charge of the battery 222 is equal to or greater than the predetermined remaining charge (step S204; Yes), the control unit 24 determines whether a predetermined time has elapsed since the previous switching to the second mode (step S205). If the predetermined time has not elapsed (step S205; No), the control unit 24 invalidates the input of the signal and displays an error on the display unit 25 (step S206).

[0052] If the predetermined time has passed since the previous switching to the second mode (step S205; Yes), the control unit 24 switches the mode of the drive unit 22 to the first mode (step S207). Whether or not the predetermined time has passed is determined based on the presence or absence of a standby time elapsed flag.

[0053] Next, the control unit 24 determines whether a predetermined period of time has elapsed since the mode of the drive unit 22 was switched to the first mode (step S208). If the predetermined period of time has not elapsed (step S208; No), the control unit 24 determines whether a signal indicating that the first changeover switch 231 has been pressed has been input (step S209).

[0054] If no signal is input (step S209; No), the control unit 24 causes the drive unit 22 to continue driving in the first mode until a predetermined period of time has elapsed or until a signal is input.

[0055] If a signal is input (step S209; Yes), the control unit 24 determines whether the signal is due to a short press (step S210). If the signal is not due to a short press (i.e., if the signal is due to a long press) (step S210; No), the control unit 24 turns off the drive unit 22 and ends the drive.

[0056] If the signal is due to a short press (step S210; Yes), the control unit 24 switches the mode of the driving unit 22 to the third mode (step S102).

[0057] If a predetermined period of time has elapsed without a signal indicating that the first changeover switch 231 is pressed being input after the mode of the drive unit 22 has been switched to the first mode (step S208; Yes), the control unit 24 automatically switches the mode of the drive unit 22 to the second mode (step S211). At this time, the control unit 24 also starts counting a predetermined period of time using a timer.

[0058] Next, the control unit 24 determines whether a signal indicating that the first changeover switch 231 is pressed has been input (step S212). If no signal has been input (step S212; No), driving in the second mode is continued until a signal is input.

[0059] If a signal is input (step S212; Yes), the control unit 24 determines whether the signal is due to a short press (step S213). If the signal is not due to a short press (i.e., if the signal is due to a long press) (step S213; No), the control unit 24 turns off the drive unit 22 and ends the drive.

[0060] If the signal is due to a short press (step S213; Yes), the control unit 24 switches the mode of the driving unit 22 to the third mode (step S102).

[0061] [Effects of the invention] As described above, the fan device 2 according to the first embodiment includes a fan 21, a drive unit 22 which drives and rotates the fan 21, an operation unit 23 which allows a user to switch the drive state of the drive unit 22, and a control unit 24 which switches the drive state of the drive unit 22 based on the user's operation of the operation unit 23. The operation unit 23 includes a first changeover switch 231 which can switch the airflow of the fan 21 among a plurality of modes, and a second changeover switch 232 which can be switched to a first mode in which the airflow of the fan 21 is a first airflow which is larger than the airflow which can be switched by the first changeover switch 231. When the second changeover switch 232 is operated, the control unit 24 drives the drive unit 22 in the first mode in which the airflow of the fan 21 is set to a first airflow which is larger than the airflow which can be switched by the first changeover switch 231, and after a predetermined period of time has elapsed, drives the drive unit 22 in the second mode in which the airflow of the fan 21 is set to a second airflow which is smaller than the first airflow and different from the airflow which can be switched by the first changeover switch 231. Therefore, when the first mode with a high airflow continues for a predetermined period of time and the control unit 24 automatically reduces the airflow of the fan 21, instead of returning to the mode before switching to the first mode (i.e., any of the third to fifth modes), the drive unit 22 switches to the second mode which has a lower airflow than the first mode and a different airflow from the third to fifth modes, regardless of the mode before switching to the first mode, so that the user does not feel uncomfortable.

[0062] The first changeover switch 231 also serves as a power switch. Therefore, the number of operation units 23 can be reduced, and the manufacturing costs of the fan device 2 can be reduced.

[0063] Furthermore, the control unit 24 disables the input of the second changeover switch 232 while the drive unit 22 is being driven in the first mode. Therefore, it is possible to prevent the user from making an operation mistake.

[0064] Furthermore, the driving unit 22 includes a battery 222, and when the mode is switched to the first mode, the control unit 24 drives the driving unit 22 in the first mode when the remaining charge of the battery 222 is equal to or greater than a predetermined remaining charge. Therefore, it is possible to prevent the drive unit 22 from being forced into the OFF state due to an unexpected loss of power in the battery 222 while the drive unit 22 is being driven in the first mode.

[0065] Furthermore, when the control unit 24 is switched to the first mode, when a predetermined time has elapsed since the end of the control operation of the drive unit 22 in the immediately preceding first mode, the control unit 24 drives the drive unit 22 again in the first mode. Therefore, excessive heat generation in the motor 221 caused by continuous driving in the first mode can be suppressed.

[0066] In addition, in FIG. 2, the drive unit 22, the operation unit 23, and the control unit 24 are integrated and connected to the fan 21 by the cable C, but the present invention is not limited to this. For example, the drive unit 22 may be a power outlet cable extending from the fan 21, and the fan 21 may be driven by being directly connected to a power source. In this case, it is preferable that the fan 21 is equipped with a motor 221 and a transmission mechanism, and that the drive unit 22 is separate from the operation unit 23 and the control unit 24. Also, for example, the fan 21, the drive unit 22, and the control unit 24 may be integrated, and the drive state of the drive unit 22 may be switched by operating an operation unit 23, which may be a separate remote control or the like, to transmit radio signals.

[0067] [Second embodiment] A fan device 2A according to the second embodiment will be described with reference to Fig. 7. Note that the same components as those in the fan device 2 according to the first embodiment will be given the same reference numerals and description thereof will be omitted. The fan device 2A according to the second embodiment has a total of six modes, including the first to fifth modes shown in the first embodiment, and a fluctuation mode that alternates between the third and fourth modes.

[0068] In the oscillation mode, the time for driving the driving unit 22 in the third mode or the fourth mode, and the time for switching between the third mode and the fourth mode are arbitrary, and for example, the driving time in the fourth mode with a low air volume may be longer than the driving time in the third mode with a high air volume. In this case, even when driving in the fourth mode, the user can feel that the same amount of air is being blown as in the third mode.

[0069] [Flow of driving state change when the first changeover switch is pressed] FIG. 7 is a flowchart showing mode switching in the fan device 2A according to the second embodiment. In the following description, the description of the steps S101 to S110 and steps S201 to S208 of the fan device 2 of the first embodiment that overlap in content will be simplified or omitted.

[0070] First, when a signal indicating that the user has pressed and held down first changeover switch 231 is input (step S101A), control unit 24A receives the signal and switches drive unit 22 to the ON state, causing it to operate in the fluctuation mode (step S102A).

[0071] Next, the control unit 24A judges whether a signal indicating that the first changeover switch 231 is pressed has been input. If no signal is being input (step S103A; No), driving in the fluctuation mode is continued until a signal is input.

[0072] If a signal is input (step S103A; Yes), the control unit 24A determines whether the signal is due to a short press (step S104A). If the signal is not due to a short press (i.e., if the signal is due to a long press) (step S104A; No), the control unit 24A turns off the drive unit 22 and ends the drive.

[0073] If the signal is due to a short press (Step S104A; Yes), the control unit 24A switches the mode of the driving unit 22 to the third mode (Step S105A). Hereinafter, the processes in steps S106A to S113A are similar to the processes in steps S103 to S110 in the first embodiment shown in FIG. 5, and therefore the description thereof will be omitted.

[0074] In addition, in the fan device 2A according to the second embodiment, when the second changeover switch 232 is pressed, when a signal of a short press of the first changeover switch 231 is input after the drive unit 22 has switched to the first mode, the control unit 24A switches the mode of the drive unit 22 to the fluctuation mode instead of the third mode, and therefore the processing is the same as that of steps S201 to S213 of the first embodiment shown in FIG. 5, and therefore description thereof will be omitted.

[0075] As described above, the fan device 2A according to the second embodiment includes a fluctuation mode in which the air volume of the fan 21 is alternately switched between the third air volume and the fourth air volume smaller than the third air volume. Therefore, it is possible to suppress wear on the drive unit 22 while maintaining the sensible temperature almost the same as when the third airflow rate is continued.

[0076] [Third embodiment] A fan device 2B according to the third embodiment will be described with reference to Figures 8 and 9. Note that the same components as those in the fan device 2 according to the first embodiment will be given the same reference numerals and the description thereof will be omitted. As shown in FIG. 8, a fan device 2B according to the third embodiment includes a single changeover switch 231B as an operation unit 23B.

[0077] (Selector switch) The changeover switch 231B is a switch that can turn the driving unit 22 ON / OFF by a long press, and can switch the mode of the driving unit 22 by a short press. When the control unit 24B switches the driving unit 22 to the ON state, the control unit 24B drives the driving unit 22 in the third mode, and cyclically switches between the fourth mode, the fifth mode, the first mode, the third mode, and so on, each time the changeover switch 231B is short pressed.

[0078] [Flow of driving state change when the changeover switch is pressed] FIG. 9 is a flowchart illustrating mode switching in the fan device 2B according to the third embodiment. In the following description, explanations of steps S101 to S110 related to the fan device 2 shown in FIG. 5 of the first embodiment and steps S201 to S208 shown in FIG. 6 that overlap will be simplified or omitted.

[0079] First, when a signal indicating that the user has pressed and held down the changeover switch 231B is input (step S101B), the control unit 24B receives the signal input from the changeover switch 231B and switches the driving unit 22 to the ON state, causing it to operate in the third mode (step S102B). Hereinafter, the processing from step S103B to step S110B is the same as steps S103 to S110 shown in FIG. 5 in the first embodiment, and is performed in accordance with the first embodiment. Since it is similar except for the fact that it is the changeover switch 231B, the explanation will be omitted.

[0080] Next, when a signal indicating that the user has pressed the changeover switch 231B briefly while the driving unit 22 is in the fifth mode is input (step S110B; Yes), the control unit 24B determines whether the remaining charge of the battery 222 of the driving unit 22 is equal to or greater than a predetermined remaining charge (step S111B). If the remaining charge of the battery 222 is not equal to or greater than the predetermined remaining charge (step S111B; No), the control unit 24B switches the mode of the driving unit 22 to the third mode (step S102B).

[0081] If the remaining charge of the battery 222 is equal to or greater than the predetermined remaining charge (step S111B; Yes), the control unit 24B determines whether a predetermined time has elapsed since switching to the second mode (step S112B). If the predetermined time has not elapsed (step S112B; No), the control unit 24B switches the mode of the drive unit 22 to the third mode (step S102B). If the predetermined time has elapsed (step S112B; Yes), the control unit 24B switches the mode of the drive unit 22 to the first mode (step S113B). The following processing from steps S114B to S119B is similar to steps S208 to S213 shown in FIG. 6 in the first embodiment, except for whether the target pressed by the user is the first changeover switch 231 or the changeover switch 231B, and therefore will not be described.

[0082] As described above, the fan device 2B of the third embodiment has a fan 21, a drive unit 22 that drives and rotates the fan 21, an operation unit 23B that allows the user to switch the drive state of the drive unit 22, and a control unit 24B that switches the drive state of the drive unit 22 based on the user's operation of the operation unit 23B, and the operation unit 23B has a change-over switch 231B that can switch the airflow of the fan 21 among a plurality of modes, and when the change-over switch 231B is switched to the first mode in which the airflow of the fan 21 is the first airflow that is the maximum, the control unit 24B drives the drive unit 22 in the first mode, and after a predetermined period of time has elapsed, drives the drive unit 22 in the second mode in which the airflow of the fan 21 is the second airflow that is smaller than the first airflow and different from the airflow that can be switched among the plurality of modes. Therefore, since the driving state of the driving unit 22 can be switched by one changeover switch 231B, the number of operation units 23 can be further reduced, and manufacturing costs can be suppressed.

[0083] [Fourth embodiment] A fan device 2C according to the fourth embodiment will be described with reference to FIG. The fan device 2C of the fourth embodiment shows an example in which the configuration of the fan devices 2 to 2B of the first to third embodiments is specifically configured with a fan section 28 including a fan 21 and a motor 221 for driving the fan 21, a power supply section 27 for driving the fan 21, and a connection section (cable) C that connects the power supply section 27 and the fan section 28. In other words, in the following description, components having the same reference numerals and names as those of the fan device 2 of the first embodiment described above have the same functions and actions.

[0084] Fan 21 has, for example, a propeller housed inside a case body, is detachably attached to fan attachment hole 13, and includes a transmission mechanism (not shown) for transmitting the rotational force of motor 221 to the propeller. The power supply unit 27 includes a battery 222 consisting of, for example, lithium ion cells, which applies the voltage required to drive the motor 221, an operation unit 23C which inputs a signal to switch the drive state of the motor 221, a monitoring unit 29 which monitors the battery 222 for overcharging, over-discharging, etc., a control unit 24C which protects the power supply unit 27 using the monitoring unit 29 and controls the switching of the drive state of the motor 221 in response to a signal received from the operation unit 23C, a display unit 25 which displays the control state by the control unit 24C, and an I / F (Interface) 26 for connecting to the fan unit 28 via a cable C or the like to control the motor 221 of the fan unit 28, or for connecting to a charger 30 to charge the battery 222.

[0085] The fan device 2C has the same functions as the fan devices 2 to 2B shown in the first to third embodiments, and provides the same effects.

[0086] [Variations] In the above first and second embodiments, the first changeover switch 231 also serves as a power switch, but this is not limited to this. The first changeover switch 231 and the power switch may be separate, and the operation unit 23 may be provided with three switches including the second changeover switch.

[0087] Furthermore, the fan device 2B according to the third embodiment described above has five modes, the first to fifth modes, like the fan device 2 according to the first embodiment, but is not limited to this and may have six modes including the fluctuation mode, like the fan device 2A according to the second embodiment. In addition, in the first to third embodiments described above, the second mode is set to have a larger airflow than the third to fifth modes, but the airflow may be between the third and fourth modes, between the fourth and fifth modes, or smaller than the fifth mode.

[0088] Furthermore, the fan devices 2 and 2B according to the first and third embodiments need to have at least four modes, the first to fourth modes, and the fan device 2A according to the second embodiment needs to have at least five modes, the first to fourth modes and the fluctuation mode.

[0089] In addition, in the second embodiment, in order to simplify the explanation, when the drive unit 22 is switched to the ON state, it is assumed that it is driven in the oscillation mode, but this is not limited to this, and it is also acceptable to drive it in a mode other than the first mode and the second mode, and switch to the oscillation mode by briefly pressing the first changeover switch 231.

[0090] Furthermore, the display unit 25 is configured to display the current mode of the drive unit 22, but is not limited to this. For example, when the battery 222 is being charged, the display unit 25 may be configured to display the current percentage of charge.

[0091] Furthermore, it goes without saying that other specific details of the structure etc. can be modified as appropriate. [Explanation of symbols]
