DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cordless iron for removing wrinkles from clothing and the like.

BACKGROUND TECHNOLOGY Conventionally, as shown in FIGS. 6 and 7, a cordless iron of this type includes a base 2 having a heater 1, and a base 2 having a heater 1.
a thermistor 3 mounted on the thermistor 3; a temperature detecting means 4 for converting a change in resistance value of the thermistor 3 into a transmission signal;
an iron main body 6 having a power supply terminal 5 connected to the iron body 6; a temperature control means 7 for controlling the temperature of the base 2 by opening and closing a relay in response to a transmission signal from the temperature detection means 4; and an electrode connected to the power supply terminal 5. 8. Notification means such as buzzer 9.
It is composed of a stand 12 equipped with a placement section 10 on which the iron body 6 is placed, and a placement detection means 11 that detects placement of the iron body 6 on the placement section 10, and the iron body 6 is placed on the stand 12. The buzzer is configured to issue a notification after a preset period of time depending on the temperature when the device is removed from the device.

That is, if the temperature when the iron main body 6 is removed from the stand 12 is high, the wrinkle smoothing effect by ironing can be obtained for a long time, so the above-mentioned predetermined time is set long, and if the temperature is low, the predetermined time is set short. was.

11 Problems to be Solved by the Invention However, with such a structure, the temperature of the base 2 of the iron main body 6 when the notification by the notification means 9 starts differs significantly depending on the ironing conditions, so there is a large variation. There was a problem that it got bigger.

In other words, the notification may start even though the base 2 temperature is high and the wrinkle smoothing effect can be obtained sufficiently.
On the contrary, use steam, mist spray, etc. to
A problem arises in that even if the temperature drops extremely, the notification does not start yet.

Therefore, ironing efficiency may be reduced, water may leak from the base 2 of the iron body 6, and the ironing may cause stains on the fabrics being ironed, clothing, etc., and there is also a risk of burns caused by the high-temperature leaking water. there were.

Therefore, the present invention aims to improve the efficiency of ironing by providing notification according to the temperature of the iron body, and also to improve safety by eliminating stains caused by water leakage and the risk of burns. The purpose is to

The second purpose is to prevent the user from feeling uncomfortable due to the notification by the notification means continuing for a long time or changing the tone during the process.

The third purpose is to improve usability by making it easy to check the power supply status of the iron body.

Furthermore, the fourth objective is to prevent water leakage when the iron body is placed on a stand and then used again, and to further improve safety and usability.

In order to solve the four problems and achieve the first object, the present invention provides a temperature detection means for detecting a base temperature, a temperature signal processing means for processing an output signal of the temperature detection means, and a notification means. , these power sources are installed in the iron itself.

In order to achieve the second object, the present invention is provided with a timer means for determining the notification time.

Further, in order to achieve the third object, the present invention is provided with an installation detection means for detecting that the iron body is placed on the stand.

Furthermore, in order to achieve the fourth object, the present invention provides a notification when the iron main body is removed from the stand when the temperature of the iron main body is below a predetermined temperature.

action The effect of this technical means is as follows.

In other words, when the iron body is removed from the stand and ironing is performed, the temperature of the base gradually decreases, but the temperature detection means and temperature signal processing means are constantly operated by the power supply to detect the temperature of the base. Therefore, the notification means can immediately start notification when the temperature drops to a predetermined temperature.

Therefore, it accurately informs the user of the need for power supply, prevents water from leaking from the base when ironing after the base temperature has dropped, and prevents stains on the fabrics being ironed, clothing, etc., and prevents high-temperature leaks. It eliminates the risk of water burns and increases safety. Furthermore, it eliminates the waste of placing the iron body on the stand unnecessarily.
It can increase the efficiency of ironing.

Furthermore, by setting the notification at a predetermined time using the timer means, it is possible to prevent the notification from continuing for a long time and to prevent changes in tone due to voltage fluctuations of the charging means, thereby eliminating discomfort to the user.

Since the above-mentioned notification is stopped by placing the iron main body on the placement part of the stand, the user can easily confirm that the iron main body is in the power supply state, which improves usability.

Furthermore, as mentioned above, if the iron body is removed from the stand again before the base temperature reaches the predetermined temperature after the notification is stopped by placing the iron body on the stand placement part, the notification means will start the notification. In order to restart
This not only prevents water from leaking from the base, but also allows accurate judgment of when ironing can begin, further improving safety and usability.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 20 denotes an iron body, and includes a base 22 having a heater 21, a vaporization chamber 23 provided in this base 22, a tank 24 for storing water disposed above the base 22, and the base 22. temperature detection means 25 such as a thermistor for detecting the temperature of 22;
a temperature signal processing means 26 for comparing and processing the output signals of with an operational amplifier or the like; a notification means 27 such as a buzzer; and a power source 28 such as a capacitor for maintaining the operating power supply voltage of the temperature signal processing means 26 and the notification means 27. , a power supply terminal 29 connected to the heater 21, and an output terminal 30 connected to the temperature signal processing means 26.

Reference numeral 31 denotes a stand, and an electrode 3 is connected to the power supply terminal 28.
2, an input terminal 33 connected to the output terminal 29,
The output of the placing part 34 on which the iron main body 20 is placed, the placing detection means 35 that detects whether or not the iron main body 20 is placed on the said placing part 34, and the temperature signal processing means 26 is inputted. , a temperature control means 37 for controlling the base 22 to a temperature set by a temperature setting button 36, and a power cord 38 for supplying power to the entire device.

To explain the operation of the above configuration, first, the iron main body 20 is placed on the mounting portion 34 of the stand 31 and the power cord 38 is turned on. In this state, the power supply terminal 29 and output terminal 30 of the iron body 20 come into contact with the electrode 32 and input terminal 33 of the stand, allowing power to be supplied, and charging of the charging means 28 in the iron body 20 is started.

Next, when the required temperature is set using the temperature setting button 36, the temperature control means 37 inputs the base temperature information from the temperature signal processing means 26 via the output terminal 30 and the input terminal 33, and reaches the set temperature. Power is supplied to the heater 21 to heat the base 22 until the temperature of the base 22 rises and becomes ready for use. Further, the operation of the notifying means 27 is latched to a halt until the temperature detecting means 25 reaches a set temperature by the action of the temperature signal processing means 26.

Here, when the iron main body 20 is removed from the stand 31 and ironing using steam is started by operating the steam button 39, the temperature of the base 22 gradually decreases due to the heat of vaporization when water vaporizes. The charging means 2
8 ensures the power supply of the temperature signal processing means 26, so that the temperature signal processing means 26 can constantly input the temperature change of the temperature detection means 25 provided on the base 22. Determine whether or not the value has decreased.

If the iron main body 20 is placed on the stand 31 before the temperature drops below the predetermined temperature, the power source 28 is only charged again and the notification means 27 continues to be in a stopped state. Remove the iron body 20 from the stand 31 again,
When the ironing is continued until the temperature falls below the predetermined temperature, the notification means 27 starts to notify based on the output of the temperature signal processing means 26.

Therefore, the user can know that the temperature of the base 22 of the iron body 20 has actually decreased to a temperature insufficient for ironing, and can accurately judge when to place the iron body on the stand. It is.

As mentioned above, when the iron main body 20 is in the temperature range where ironing is effective, the notification means 27 does not notify, so the user cannot continue ironing until the notification is issued. This eliminates the need to unnecessarily return the iron to the stand mid-way through the process, improving ironing efficiency.

In addition, since the notification temperature is set above the temperature at which water leaks occur, the configuration that sends notification according to the temperature of the base 22 reliably prevents water from leaking from the base 22, and irons. This eliminates the risk of staining fibers or clothing, or causing burns from hot water leaking from the base 22, improving workability and safety.

In the embodiment shown in FIG. 3, a timer means is provided to stop the notification by the notification means 27 after a predetermined time.
Compared to the one in which the notification means 27 continues notification, the power source 2
Since the voltage fluctuation of 8 is small, there is almost no change in tone color during notification, and there is an effect that the user does not feel uncomfortable. Furthermore, since the notification is stopped after a predetermined time, there is only a slight drop in the voltage of the power source 28, and when the iron body 20 is returned to the stand, it can be recharged in a short time, even when used repeatedly. It also has the effect of providing stable charging.

In the embodiment shown in FIG. 4, the notification by the notification means 27 is stopped when the iron body 20 is placed on the stand 31, so that it can be easily and reliably confirmed that the iron body 20 has entered the power supply state. This means that ironing is done more efficiently (ironing is done, and the usability is improved).

In the embodiment shown in FIG. 5, the notification by the notification means 27 is stopped when the iron body 20 is placed on the stand 31, and before the base temperature of the iron body 20 rises to a predetermined temperature or higher and recovers, When the iron main body 20 is removed from the stand 31, the notification means 27 repeatedly notifies the user that the iron main body 20 has entered the power supply state. This prevents water from leaking from the base 22 by starting ironing before the temperature has recovered to the required temperature. That is, if the temperature of the base 22 of the iron body 20 is outside the temperature range necessary for ironing, the notification means 27 will surely notify when the iron body 20 is removed from the stand 31. .

Effects of the Invention As described above, the present invention provides a notification according to the temperature of the base before the base temperature drops to such a temperature that the wrinkle smoothing effect by ironing cannot be obtained or water cannot evaporate. Since it tells you when to place the main body on the stand, ironing efficiency is improved, and safety is also improved because there is no hot water spewing out from the base.

Furthermore, since the present invention stops the notification that the iron body is placed on the stand after a predetermined period of time, the unpleasant notification does not continue for a long time, and the tone does not change due to fluctuations in the power supply voltage, causing discomfort to the user. This has the effect of eliminating the need to give

Further, the present invention has the effect of further improving usability by making the above-mentioned notification stop when the iron body is placed on the stand, so that it can be reliably confirmed that the iron body is in the power supply state.

Furthermore, in the present invention, when the base temperature of the iron body is outside the temperature range required for ironing, the notification means reliably issues a notification when the iron body is removed from the stand, so that the iron can be ironed efficiently. In addition to being usable, there is no boiling water spewing out from the base, which has the effect of further improving safety and usability.
