Abstract

PURPOSE:To stabilize the jet of steam under the work of ironing and improve the effect of finish by arranging a feed water controlling means for controlling a motor pump for feeding water in a tank to a carbureter, and a state detecting means for detecting the unused state of an iron. CONSTITUTION:An iron is horizontally set, and a steam button 9 is pushed, and when steam setting order is applied to a feed water controlling means 8, then by the means 8, a motor pump 5 is worked, and water is fed to a carbureter 3 in an iron 4 through a feed water port 6 and a feed water channel 7. The water is turned into steam by the heat of a base 1, and steam ironing can be executed. In this case, by the feed water controlling means 8, the output of a state detecting means 10 is always identified, and it is judged that the iron is in a used state if a horizontal state and an independent state are alternately repeated in a period shorter than a specified time T, and the motor pump 5 is worked, and feed water is controlled. Accordingly, in case that the steam ironing is normally executed, stable steam can be always obtained. After that, in case that the iron is set in the independent state, the output of the independent state is directed to the feed water controlling means 8 from the state detecting means 10, and the specified time T later, the working of the motor pump 5 is stopped.

Description

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

BACKGROUND OF THE INVENTION Conventionally, this type of ironing device has had a structure as shown in FIG.

That is, a base 14 having a heater 13, a vaporization chamber 15 formed on the base 14, a tank 16 disposed above the base 14, and an electric pump 17 that supplies water in the tank 16 to the vaporization chamber 15. and said tank 1
Vibrator 18 that sucks water from 6 to the electric pump 17
, a water supply pipe 19 that supplies water from the electric pump 17 to the vaporization chamber 15, a control circuit 20 that controls the temperature of the iron and the electric pump 17, a steam button 21 that sets the steam, and a self-supporting iron. It has a self-supporting detection means 22 for detecting the state, and when the self-supporting state detecting means 22 detects the self-supporting state of the iron, the control circuit 20 immediately stops the electric pump 17 and stops the generation of steam. .

Problems to be Solved by the Invention However, with such a structure, when ironing is performed while pressing the steam button 21 and operating the electric pump 17 to blow out steam, the self-standing detection means 22 Since the inner ball moves back and forth, the output of the self-standing detection means 22 is a repetition of the horizontal state signal of the iron and the self-standing state signal, and as mentioned above, in the self-standing state, the electric pump 17 immediately stops and the generation of steam stops. Because of this structure, there was a problem that the steam would frequently stop due to the movement of the iron during normal ironing.

Therefore, an object of the present invention is to stabilize the jetting of steam during ironing and to improve the finishing effect of ironing.

Means for Solving the Problems And, in order to achieve the above objects, the present invention provides an electric pump that supplies water in a tank to a vaporization chamber, a water supply control means that controls the electric pump, and an iron that is not in use. The electric pump is provided with a state detecting means for detecting the iron, and stops the operation of the electric pump when the state detecting means detects the self-standing state of the iron for a predetermined period of time.

Function The steam iron of the present invention has the above-mentioned configuration, so that when the electric pump is activated to put the iron in a self-standing state during steam ironing, the state detection means detects that the iron is not in use and detects when a predetermined period of time has elapsed. Since the electric pump stops operating afterwards, there is no steam ejection when the iron is standing on its own, making it safe.In addition, when the electric pump is operating and steam ironing is being performed, the status detection detects the iron's stand-alone state as described above. Since the electric pump will not stop operating unless it continues for a specified period of time, steam generation will not stop frequently and stable steam generation will always be obtained, improving the finish quality of ironing. This is the result.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. 1 and 2, 1 is a base having a heater 2, 3 is a vaporization chamber formed in this base 1, 4 is a tank disposed above the base 1, and 5 is the tank 4.
6 is a water supply port that sends water in the tank 4 to the electric pump 5; 7 is a water supply channel that connects the electric pump 5 to the vaporization chamber 3; 8 is the electric pump 5, and the iron stands alone for a predetermined period of time (T).
A water supply control means having a function of stopping the operation of the electric pump 5 if the operation continues; 9 a steam button for setting the water supply to the water supply control means 8; 10 connected to the water supply control means 8;
This is a state detection means for detecting the freestanding state and horizontal state of the iron, and is composed of a photo sensor 11 and a spherical movable body 12.

The operation of the above configuration will be explained next.

To use steam, first place the iron horizontally and press the steam button 9, then issue a steam setting command to the water supply control means 8.The water supply control means 8 operates the electric pump 5 to supply water in the tank 4. It is supplied to the vaporization chamber 3 through the port 6 and the water supply channel 7.

The water turns into steam due to the heat of the base 1, and steam ironing can be performed. At this time, the water supply control means 8 always checks the output of the state detection means 10, and if the iron alternately repeats the horizontal state and the freestanding state at a cycle shorter than a predetermined time (T), the iron is in the operating state. The determination is made, and the electric pump 5 is operated to perform water supply control. Therefore, when performing normal steam ironing, stable steam is always obtained without the steam jetting stopping.

Next, when the worker sets the iron to a free-standing state in order to correct the condition of the clothes or the like being ironed, the state detecting means 10 outputs the free-standing state to the water supply control means 8.

The water supply control means 8 uses its output to stop the operation of the electric pump 5 after a predetermined time (T 2 ) has elapsed. Therefore, when the iron stands on its own, no high temperature steam is ejected from the base 1, and there is no risk of burns or the like.

Also, when you want to use steam iron again, you can get a jet of steam by simply returning the iron to a horizontal position.

As mentioned above, when you move the iron to iron, you will always get a steady stream of steam, and if you let the iron stand on its own, the steam will stop blowing out, improving safety. .

Effects of the Invention As described above, the present invention provides a method for ironing by stopping the operation of the electric pump after the state detection means detects the self-supporting state of the iron and continues that state for a predetermined period of time. In other words, when the output of the condition detection means frequently repeats the horizontal state and the self-standing state, the generation of steam does not stop and a stable jet of steam is always obtained, making it possible to improve the finishing effect of ironing. It becomes.

Further, when the iron is in a free-standing state, there is no ejection of high-temperature steam from the base, so a steam iron that can be used safely without the risk of burns or the like can be obtained.
