Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention controls the base temperature to the optimum temperature according to the material of the fiber being ironed. At the same time, the iron generates an appropriate amount of steam that is controlled according to the temperature. It is related to

0002

[Conventional technology]

Conventional general steam-generating irons have a base with a vaporizing chamber as a heater. The temperature is controlled to the set temperature based on the base hanging surface temperature information from the hanging surface sensor. A fixed amount of water is naturally dripped into the vaporization chamber from the dripping nozzle installed at the bottom of the tank containing The steam generated is ejected from the steam hole provided in the base. Ru.

0003 In this case, if the temperature of the vaporization chamber is high, the water evaporation capacity is high, and if the temperature is low, the water evaporates. Because the ability is low, it is generally recommended for ironing "cotton", which is frequently used. The amount of water dripped is adjusted to the appropriate temperature of about 170°C.

0004 Therefore, in the case of ``linen'', which is ironed at a higher temperature than ``cotton'', the amount of steam Due to the lack of iron, the wrinkles cannot be smoothed out and spraying is required, and the ironing temperature is lower than that for cotton. In the case of materials such as "synthetic fibers" with a low level of water, the water that is applied may not evaporate completely and come out of the steam holes, causing the fabric to dry. To avoid staining the fabric, turn off the steam and iron, or iron at a "cotton" temperature. I either turned on the steam, applied a cloth, and quickly ironed it.

[0005] For example, JP-A-Sho, which changes the amount of steam depending on the base temperature of the iron, 62-286500 and Japanese Patent Application Laid-Open No. 1-146591. A pump that pumps water and a control device that controls the amount of water sent by the pump based on the output of the hanging surface sensor. Some have a certain position.

[0006] Also, as disclosed in Japanese Patent Application Laid-Open No. 59-222200, there is a valve that opens and closes the dripping of water into the vaporization chamber. The solenoid that controls the lubricant, or the It has a pump that sends water to the oxidation chamber, and uses a control means to send water in an amount that corresponds to the set temperature. There is.

[0007]

[Problem that the idea aims to solve]

Conventional general irons that generate steam depend on the temperature of the vaporization chamber and base. A fixed amount of water is naturally dripped into the vaporization chamber from the dripping nozzle installed at the bottom of the tank containing water. I'm letting it go down.

[0008] Therefore, if the base surface temperature of the iron body is set to "high temperature", the amount of steam If the temperature is insufficient and you set it to "low temperature", the evaporation capacity will be insufficient and water will come out from the steam hole. There were times when I ended up losing my job. The pump that controls the water flow rate based on the output of the hanging surface sensor is based on the temperature of the base hanging surface. The higher the temperature, the more water will be supplied, but the water supply will lower the temperature of the vaporization chamber to the base hanging surface. Since the temperature drops by 20 to 50 degrees Celsius, if the iron is set to "low", the water will not be pumped. All of the water may not evaporate and a small amount of water droplets may come out from the steam hole.

[0009] In addition, the type that sends water in an amount according to the set temperature has a steam amount that depends on the fiber material. can be set, but as above, it does not correspond to the temperature of the vaporization chamber, so similarly, a small amount of There is a risk of water droplets coming out.

0010

[Means to solve the problem]

This invention was made in order to solve the above problem, and it is necessary to install a heater. The base includes a vaporizing chamber and a vaporizing chamber temperature detection means for detecting the temperature of the vaporizing chamber; and a base temperature detection means for detecting temperature, the pump supplying water to the vaporization chamber. A valve switch is provided to control the valve and the valve, and the valve switch controls the amount of water per hour to the vaporization chamber. A device connected to a base temperature detection means that controls the operation duty of the valve switch supplied to the And so.

[0011]

[Effect]

The base temperature detection means and the vaporization chamber temperature detection means detect the temperature at two places: the base and the vaporization chamber. When the temperature of the vaporization chamber becomes lower than the set temperature, the temperature of the vaporization chamber is detected. The amount of water dripping from the water can be reduced depending on the temperature using a pump and valve that are controlled by a valve switch. When the temperature of the heater rises above a certain temperature, the temperature can be reduced by stopping the power to the heater. Apply an appropriate amount of steam within the temperature range suitable for ironing fiber, wool, cotton, and linen fabrics. It can be issued.

By sensing each other, it is recognized that the iron is being used, and the base 42 is detected. Valve switch 1 such as a solenoid with ON/OFF duty as shown in Figure 3 depending on the temperature. 1 operates and moves the pump 44 and valve 45 to draw water in the tank 46 to the base. When the amount fed into the vaporizing chamber 43 of 42 is adjusted and the iron main body 51 is made to stand on its own, After a certain period of time, the valve switch 11, such as a solenoid, is stopped at the side where the water flow stops.

[0038] When water starts to be sent to the vaporization chamber 43, the base temperature of the thermistor etc. The detection temperature of the detection means 28 and the vaporizing chamber temperature detection means 27 were almost the same as in 28. A difference begins to appear in the detected temperatures of 27. At this time, the detection temperature range of the thermistor is A, B, Divided into four areas, C and D, as shown in Table 1, the output of switch 3 such as a relay is determined for each area.

[0039]

[Table 1]

[0040] is under control. The main temperature control of the base 42 depends on the thermistor 28 (conditions Condition 1) If the temperature of the vaporization chamber 43 falls below the set temperature T by β℃, then condition 2 The switch 3 such as a relay is turned on and the heater 2 is energized, and the vaporization chamber 43 (iron bay) is turned on. This prevents a drop in temperature at the tip of the device. However, if this condition continues for a long time, the base 42 Thermistor 2 detects the temperature range D where the rear side temperature rises and is α℃ higher than the set temperature T. When 8 is detected, switch 3 such as a relay is turned OFF and the switch is switched to heater 2 as in condition 4. Turn off the power.

[0041] However, if the detected temperature becomes low as shown in Figure 4, the valve opening/closing device such as a solenoid 11 is lowered and the amount of water sent to the vaporization chamber 43 is reduced. The base 42 temperature approaches the set temperature T. α and β, which set the temperature range, are the set temperature. Therefore, each fabric can be ironed by setting the temperature to a temperature that does not interfere with ironing. Generates the appropriate temperature and amount of steam.

[0042]
