Abstract

PURPOSE:To safely use an iron without damaging clothing or the like by adding a device, which can set a base temperature to be high over a normal settable temperature range, and lowering the base temperature after a prescribed time. CONSTITUTION:In correspondence to the material of the clothing to be ironed, a work is executed with matching to suitable temperature in the general range of 80-200 deg.C by a temperature setting means 5. At such a time, when the cloth is cotton, etc., and a creases-stretching effect is not be enough obtained even at a normal maximum temperature, an operating means 7 is operated so as to operate the device which can set the base temperature to be high over the normal maximum temperature. At such a time, the base temperature rises up further up to the prescribed temperature, which is determined in advance, and a display means 8 and an announcing means 9 are operated and promote attention. On the other hand, after the prescribed time passes, the base temperature falls down. Then, since the temperature returns to the original temperature, the creases stretching can be effectively executed and the iron can be safely used. Then, since the operating means 7 is separated from the normal temperature setting means 5, the malfunction of a worker can be prevented.

Description

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

Conventional technology Conventionally, this type of iron has been designed so that the base surface temperature can be adjusted arbitrarily depending on the type of fiber. Generally, it is possible to set the

Problems to be Solved by the Invention However, there is a problem in that in such a temperature range, the finish of cotton products is poor and wrinkles are difficult to remove.

Due to the nature of the material, cotton products can be heated to high temperatures of 200°C or higher to remove wrinkles and be efficient.
When ironing clothes at home, clothes made of various fibers are processed at the same time, so many chemical fibers are susceptible to heat, and many of them are burnt or damaged, and most items can be finished at temperatures below 200°C.

In addition, in actual ironing, most fibers are ironed at a high temperature, except for some fibers that are particularly sensitive to heat. If you set the temperature high to C, you will burn your clothes if you are not conscious of the temperature.So far, if you set it high, the maximum temperature is around 200℃, which is relatively rough except for a few. Although ironing is possible, it is necessary to carefully examine the type of fiber and carefully set the settings, and it may warp and become difficult to use, so simply expanding the temperature adjustment range and increasing the maximum temperature is not recommended from the actual usage situation. In addition, simply increasing the maximum temperature requires ensuring safety by making the structure of the iron and the materials used heat-resistant so that it can be used at that temperature for a long period of time. However, because the temperature is not normally used, it would be expensive and impractical, so it could not be realized.

Therefore, the present invention enables the operator to set the temperature even higher than the maximum temperature in the normal temperature control range when a particularly high temperature is required for cotton etc. The first purpose is to provide a device.

The second purpose is to make the operator aware that the temperature is higher than the normal maximum temperature, and to apply pressure so that the temperature can be used safely without damaging other clothing.

The third purpose is to further improve the finishing effect by increasing the temperature even higher than the normal maximum temperature.

Means for Solving the Problems And in order to achieve the above first object, the present invention includes:
In addition to adding a device that can set the temperature higher than the normal settable temperature range, it also lowers the temperature after a predetermined time.

Further, in order to achieve the second object, the present invention provides the device with an operation means separate from the normal temperature setting means, or displays or notifies when the device operates, and further, A safety device is provided that activates when the temperature or time specified by the device is exceeded.

Furthermore, in order to achieve the third object, the present invention increases the heater capacity when the device is operated.

Function: The iron of the present invention has the above-mentioned configuration, and can improve wrinkle removal by ironing at a higher temperature than the normal maximum temperature for finishing SRS products that are difficult to remove wrinkles at normal temperatures among clothes to be ironed. Moreover, since the temperature returns to a low temperature after a predetermined period of time, it can be safely used on other fibers without failure. As a result, the operator can be conscious and careful when using this device, while also being easy to use without having to worry about setting the temperature like a conventional iron.

Furthermore, by operating this device, the heater capacity can be increased, which not only supplements the amount of heat required to generate steam and makes it easier to maintain the temperature, but also increases the amount of steam, making it possible to control the temperature. In addition, the steam performance can be improved to further enhance the finishing effect, and the device can quickly set a higher temperature.

EXAMPLE An example of the present invention will be described below with reference to the accompanying drawings. In Figures 1 and 2, 1 is the iron heater, 2
is a temperature control means constituted by a control circuit for controlling the temperature of the iron, and has a temperature detection means 3 such as a thermistor for detecting the temperature of the iron.

4 is a relay, and 6 is a temperature setting means for setting the base of the iron to a desired temperature, including "off" and 80°C to 200°C.
A plurality of stages are provided so that an operator can set a desired temperature according to the type of fiber to be ironed within the general temperature range of 'Q, and is provided with a display means 6 using an LED or the like.

7 is an operating means for the device that is set to a higher temperature than the maximum temperature in the temperature range adjusted by the normal temperature setting means 6;
For example, if you operate the iron while using the iron at the maximum temperature of 200'C, the base temperature can be raised to 240°C, which is 70°C higher, as shown in Figure 2, and after a predetermined time (1). You can lower the temperature and then return it to the actual set temperature. Such control can be easily achieved using a microcomputer, but it goes without saying that similar control can also be achieved using circuits. It is used to finish sheets and other S products that are effective, and it is heated to a low temperature after a specified period of time to prevent adverse thermal effects on the structure of each part of the iron and control electronic components, etc., and the time σ) is also compared. Set it to a short time. Therefore, if the temperature drops midway through, it is possible to raise the temperature again using the operating means 7. Furthermore, since such devices are abnormally high in temperature compared to the normal operating temperature range, erroneous operation and misuse can be prevented by providing a separate means for setting the temperature so that workers can be aware of this and use it only when necessary. Not only can this be prevented, but it also reduces the temperature after a predetermined period of time, thereby preventing accidents caused by overheating. 8 is a display means that is displayed when the operating means 7 is operated, and starts blinking when the operating means 7 is operated;
When a predetermined temperature is reached, the blinking cycle including the lighting may be changed.

Reference numeral 9 denotes a notification means operated by the operation means 7, which starts notification when the operation means 7 is operated, may continue notification until the temperature becomes low, and changes the sound when a predetermined temperature is reached. You can also let me know.

In this way, by using various methods to alert workers that the temperature is higher than the normal maximum temperature, it is possible to ensure that the temperature does not drop after a certain period of time and that the temperature can be used more safely. .

Next, the operation of the configuration of this embodiment will be explained. First, we will explain normal ironing work. Depending on the material of the clothes to be ironed, the temperature setting means 6 is set to an appropriate temperature in the general range of 80'C to 200'C. At this time, if the wrinkle removal effect is not sufficient even at the normal maximum temperature for cotton products, for example, the operation means 7 is used to operate a device that can set the temperature higher than the normal maximum temperature.
operate. At this time, the pace further increases to a predetermined temperature. At this time, the display means 8 and the notification means 9 operate to call attention, and after a predetermined time, the temperature is lowered and returned to the normal temperature to effectively smooth out wrinkles.
and can be used safely. By separating the operating means 7 from the normal temperature setting means 6, it is possible to prevent the operator from erroneous operation.

FIG. 3 is a circuit diagram showing another embodiment, in which a triac 1o is provided in place of the relay 4 shown in FIG. 1, so that the capacity of the heater 1 can be switched.

That is, by operating the operating means A, the capacity of the heater 1 can be changed arbitrarily from, for example, the normal 700W to 1KW.

Therefore, as shown in Fig. 4, even if the temperature difference T to be raised from the operating temperature is large, if the capacity is 1 ton or constant, it will take 70 hours, but by increasing the capacity, the waiting time will be reduced to 1 hour. In addition to reducing the amount of steam loss, it is also possible to increase the amount of steam ejected and eject a larger amount of steam at a higher temperature.

As a result, the finish effect when ironing #B products can be significantly improved.

In addition, it is desirable that sufficient safety devices be taken into consideration to enable use at such high temperatures, e.g.
When used at a temperature higher than the normal maximum temperature, a safety device can be provided that operates when the temperature exceeds a predetermined temperature or when the temperature does not drop for a predetermined time.

In addition, ironing is usually more efficient if you start with the items with a lower temperature and then finish with items with a higher temperature. This is because it takes time to lower the temperature of the iron during the process, resulting in waiting time.

Based on such a work analysis, it is conceivable that the device of the invention is also used at the end of ironing. Therefore, in the above embodiment, when the device is operated, the temperature is lowered after a predetermined time and returns to the original temperature, but the heater circuit is turned off.
It may be set to F. At this time, it can also function as a safety device to prevent forgetting to turn it off after use.

Effects of the Invention As described above, the present invention adds a device that can set the base temperature higher than the normal settable temperature range, and also lowers the base temperature after a predetermined time. It is now possible to iron at a higher temperature than the normal maximum temperature, and it has a particularly good wrinkle smoothing effect on cotton products, and there is no need to worry about having to reset the settings after continuous use for a long time. A safe and easy-to-use iron that is less likely to damage the main body or burn clothes can be obtained.

Further, the present invention can reliably prevent erroneous operation or misuse by the operator by providing an operating means separately from the normal temperature means, or by providing a display means or a notification means that is activated by the operation of the same means.

Furthermore, according to the present invention, since the heater capacity can be changed by operating the same means, it is possible to shorten the temperature rise time and increase the amount of steam ejected, thereby reducing loss time and further improving the finishing effect. be.
