Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Industrial Application Field This invention is based on E! A is to control the optimum amount of steam depending on the temperature of the base surface of the iron, and to provide an iron that does not cause water to flow out.

BACKGROUND OF THE INVENTION Conventional steam irons have a structure in which water is naturally dripped into a vaporizing chamber from a dripping nozzle provided at the bottom of a water tank, and the generated steam is ejected through a steam hole provided in a base. In this case, if the temperature of the base has not risen sufficiently, there is a problem in that when water is dropped, insufficient p-water flows out of the steam holes or water accumulates in the vaporization chamber, corroding the base. As a countermeasure for this, a bimetal driven valve is installed in the water passage leading from the water tank to the vaporization chamber of the base, and when the temperature of the base is low, this passage is closed to prevent water from being sent to the vaporization chamber of the base. There was a method.

Problems to be Solved by the Invention Even with conventional irons that have a valve driven by this bimetal, the amount of steam is almost constant regardless of the temperature of the base surface, due to the amount of water naturally falling from the dripping nozzle at the bottom of the water tank. It is a fixed amount.

Therefore, if you open the drip nozzle while the base surface temperature is set low, the base surface temperature will drop too much and will no longer be suitable for ironing.

Also, when you set it to a high temperature, the amount of steam may not be enough.

The present invention aims to solve the above problems and produce an optimum amount of steam depending on the base surface temperature.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention provides a temperature sensing element on the base surface of the iron, applies a signal from the temperature sensing element to the pump driving device, and the pump driving device , which drives the pump and sends the optimum amount of water to the base's vaporization chamber according to the base surface temperature.

As described above, according to the present invention, the pump drive device generates a pump drive voltage or a frequency according to the base surface temperature based on the signal from the temperature detection element that detects the base surface temperature of the iron. Output a signal. The pump is driven by the pump drive signal, and the amount of steam can be obtained in accordance with the temperature of the base surface of the iron.

Example Examples thereof will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is a heater that heats the base 2 of the iron, 3 is a temperature detection element that detects the temperature of the base 2, and 4 is a heater that heats the base 2 of the iron.
5 is a pump drive device which inputs the signal of the temperature detection element 3 and outputs a signal to drive the pump according to the signal of the temperature detection element 3, and 5 is a pump for sending water from the water tank to the base vaporization chamber of the iron. be.

Note that it is also possible to drive the temperature control device and the like based on the signal from the temperature detection element 3 to control the heater 1 and perform temperature control.

Figure 2 shows the state mounted on the iron, 7 is the base 2
In the vaporization chamber provided inside, water enters and vaporizes, and steam is ejected from the steam hole 12.

The temperature detection element 3 is attached to the base 2 and thereby detects the temperature of the base 2. The temperature detection signal is sent to the pump drive device 4. The output signal of the bomb drive device 4 is sent to the pump 5, and the pump 5 is driven so that the amount of steam corresponding to the base temperature is obtained. 11 is a water tank, water 8
Contains.

It is connected to the pump 5 by a tube 9 provided at the bottom of the water tank 11, and further connected to the vaporization chamber 7 in the base 2 via the pump 5 by a tube 10.

Therefore, when the base temperature is high, a lot of water enters the vaporization chamber 7, and when the base temperature is low, less water enters the vaporization chamber 7Vc.
The optimum amount of steam can be obtained depending on the base temperature.

If the base temperature is lower than the water vaporization temperature and the water does not become steam even when sent to the vaporization chamber of base 2, stop the operation of the pump 5 and prevent the water from flowing to the vaporization chamber 7. It is natural to do so.

Incidentally, it is natural to stop the operation of the pump 6 when using a dry iron instead of a steam iron.

Effects of the Invention As described above, according to the present invention, an optimum amount of steam can be obtained depending on the temperature of the iron base. That is, if the temperature is set according to the type of cloth, the optimum amount of steam can be obtained accordingly, and an iron that is easy to use can be obtained.
