Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cordless steam iron used in general households.

BACKGROUND OF THE INVENTION As shown in FIG. 3, a conventional cordless steam iron has a cassette-type water tank 2 attached to the iron body 1, similar to a normal corded steam iron.
When this iron main body 1 is set on an iron stand 3, a control circuit 4 provided in the iron stand 3
The configuration is such that the heater 5 is energized by the action of. In this configuration, in order to improve the operability that is a feature of cordless irons, the capacity of the water tank has been halved, and compared to the normal capacity of 180 to 220, the water tank capacity is 80 to 120Ω.
It was common to have a degree of

Furthermore, when in use, the water tank 2 is removed and water is supplied as before, and when the use is finished, the water tank 2 is re-attached.
The structure was such that water could be drained by removing it.

Problems to be Solved by the Invention However, with such a structure, the capacity of the water tank is smaller than that of a normal steam iron, which limits the duration of the steam and requires frequent replenishment of water.
There was a problem in that the effect of improving operability obtained by going cordless was offset.

Furthermore, although this is a conventional problem common to corded and cordless models, when water remains in the water tank at the end of use, it is often stored as is because it is troublesome to drain the water. Sometimes there were problems such as water flowing out.

Therefore, in order to maximize the operability of a cordless steam iron, the first object of the present invention is to make it possible to supply additional water without having to remove or attach the water tank while using the iron.

The second purpose is to enable the water tank to be drained by switching the drainage route with a simple operation at the end of use.

Means for Solving the Problems In order to achieve the above-mentioned first object, the present invention provides a main tank for storing water and a water pump in the iron stand, and when the iron body is attached. This allows water to be supplied to the water tank in the iron itself.

Furthermore, in order to achieve the second object, the present invention includes a part of the water supply path from the main tank to the water tank of the iron body.
A bypass route that does not pass through a water supply pump is provided, and a water channel switch can be used to switch between this bypass route and the original water supply route.

Function The cordless steam iron of the present invention has the above-mentioned structure, so there is no need to perform complicated operations such as removing the water tank and refilling water while using the iron. This system ensures that the required amount of water is always kept in the water tank during use.

In addition, between the water tank and the main tank 1: A drainage device with a bypass path is installed, when the iron body is attached to the iron stand, the remaining water in the water tank that is no longer needed can be drained from the main tank by simply switching the path with the water channel switch. This allows water to drain into the tank.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, reference numeral 6 denotes an iron body, which is equipped with a heater 7° and a vaporization chamber 8, and a small water tank 10 built therein and communicated with the vaporization chamber 8 through a nozzle 9. This water tank 10 has a significantly reduced water storage capacity compared to the water tank 2 of the conventional cordless steam iron shown in FIG. 2 is about 80-120cc).

11 is a check valve such as a ball valve provided in a part of the water tank 10, and 12 is a steam button that opens and closes the nozzle 9 to control the generation of steam.

Reference numeral 13 denotes an iron stand, which is configured so that the iron body 6 can be placed thereon when the iron body is being ironed.When the iron body 6 is set on the iron stand 13, the terminal 14 connected to the heater 7 of the iron body 6 is , comes into contact with a contact 15 provided on the ironing stand 13, and the heater 7 is energized. Reference numeral 16 denotes a control circuit that controls power supply to the heater 7. 17 is a pump provided within the ironing stand 13, and 18 is a main tank which is also provided within the ironing stand 13 and can store a large amount of water. This pump 17 is for supplying water from the main tank 18 to the water tank 10 inside the iron body 6 when the iron body 6 is set on the iron stand 13. 19
is a water supply pipe communicating with the discharge port of the pump 17.

Next, the operation of an embodiment based on FIG. 1 will be explained. First, main tank 1 inside ironing stand 13
(The water inlet of the main tank 18 is not particularly shown), and when the iron body 6 is set on the iron stand 13, the heater 7 is
is energized. At the same time, a water supply port 19 from the pump is connected to a check valve 11 provided in a water tank 10 in the iron body 6.
, and water is supplied from the main tank 18 to the water tank 10 by the action of the pump 17.

In this way, when the heater 7 reaches a predetermined temperature, the iron body 6 is removed from the iron stand 13 and ironing is performed.At this time, when the steam button 12 is operated to open the nozzle 9, Water stored in the water tank 10 drips into the vaporization chamber 8 from the nozzle 9, and steam can be generated.

At this time, there is only water around 10Ω in the water tank 10, but generally the water used to generate steam is about 6 to 8cc per minute, and there is no need to stop after ironing starts. It has been experimentally confirmed that the average time it takes to set the iron on the iron stand 13 is about 10 seconds. Furthermore, when ironing is stopped, that is, when the iron body 6 is set on the iron stand 13, the heater 7 is heated again as described above, and water is supplied to the water tank 10. Water storage capacity of water tank 10:
! It can be seen that 1locc is a necessary and sufficient amount.

Next, another embodiment will be described based on FIG. 2.

In FIG. 2, reference numeral 20 denotes a water channel switching device provided between the pump 17 and the water supply vibrator 19, and 21 indicates a bypass path that directly connects the water supply vibe 19 to the main tank 18 by the action of the water channel switching device 20.

To explain the operation in this figure, when the above-mentioned ironing is finished and the use of the iron body 6 is finished, the iron body 6 is set on the iron stand 13, so the water tank 1o is still filled with about 10Ω. There will be some water left.

It is well known that if this water is left without being drained, scale will accumulate in the narrow water tank 10, which will likely cause the nozzle 9 to become clogged. Therefore, when the water channel switch 20 is operated at the end of ironing,
The water supply vibrator 19 is directly connected to the main tank 18 via a bypass path 21 without passing through the pump 17. As a result, the remaining water in the water tank 10 is quickly removed from the main tank 18.
can be drained to.

In addition, although the operation method of the pump 17 and the operation method of the waterway switching device 20 are not particularly explained in the embodiment, it is easy to operate these operations automatically using the control circuit 16, and in some cases Depending on the situation, manual operation may also be possible.

Further, in the embodiment, an example was shown in which a ball valve was used as the check valve 11 of the water tank 10, but any type of check valve that does not leak water during ironing may be used, and a simpler check valve may be used. I don't mind.

Effects of the Invention As described above, the present invention includes a main tank for storing water and a water supply pump inside the iron stand, and the capacity of the water tank inside the iron body is significantly reduced.
The iron body can be made significantly lighter (approximately 100g lighter) and more compact, and the ease of use, which is a feature of cordless irons, is greatly improved.

Further, in the present invention, a bypass path is provided in a part of the water supply path from the main tank to the water tank, and the remaining water in the water tank can be easily drained through this bypass path when ironing is finished. It is extremely easy to use and extremely practical as it does not cause nozzle clogging due to leftover water, which was a problem in the past, and there is no need to take the trouble to remove the water tank to drain the water. It's expensive.
