Abstract

PURPOSE:To need no operating force for pushing down a steam button to be required for feeding water in a tank to a carbureter chamber repeatedly and to improve operability at the time of jetting steam by setting an electrically- driven water feeder as a means for feeding the water in the tank to the carbureter chamber, and by driving the water feeder at specified intervals. CONSTITUTION:When a lot of steam is needed for the moment, then by pushing a switch 36 for increased steam once for example, electrification to a solenoid is turned ON/OFF at specified intervals with an electron circuit or the like, automatically. Then, the excitation and non-excitation of the solenoid are cylindrically repeated, and so the vertical movement of a pump device 30 is repeated, and a lot of water can be forcibly fed to a carbureter chamber 12 via a drop nozzle 22. As this result, the increased steam is obtained. Then, in order to jet the increased steam, said switch 36 for the increased steam may be just pushed, and a great operating force and a pushing-down quantity are not needed, and operability can be extremely improved.

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.

2. Description of the Related Art Conventionally, as shown in FIG. 6, this type of steam iron has a base 38 having a heater 37, a vaporizing chamber 39 provided on the base 38, and a tank 40 for storing water to be supplied to the vaporizing chamber 39. Then, the water in this tank 40 is transferred to the vaporization chamber 39.
The water supply device 41 includes a steam button 4 which is formed to protrude from the handle 42.
3, a spring that urges the steam button upward, a backing 44 attached to the steam button 43, a cylinder 45, a water suction pipe 46 provided in the cylinder portion 45, and a discharge pipe 47. It is formed by the water suction pipe 46 and the check valve 48 provided in the discharge pipe 47, and the steam button 43
When the steam button 43 is operated again, the water in the tank 4° passes through the water suction pipe 46 and is stored in the cylinder 45, and when the steam button 43 is operated again, the stored water is sent to the vaporization chamber 39 through the discharge pipe 47. Base 3 is vaporized here as steam.
It was common to have a structure in which the water was ejected from 8.

Problems to be Solved by the Invention However, with such a configuration, in order to blow out steam, the steam button 43 protruding from the handle 42 must be pushed down against the spring force, which requires a strong pressing force for operation. Not only that, but also the amount of push-up was large, making it extremely difficult to operate.

Furthermore, the speed and interval of operation of the steam button 43, which blows out steam, differs depending on the operator.
There were irregularities in the amount of steam ejected, and because water exceeding the vaporization capacity of the vaporization chamber 39 was sent to the vaporization chamber 39, hot water was ejected from the base. However, as mentioned above, the operability of the steam button 43 is poor, and the steam button 43 must be pressed every time steam is to be ejected, which makes operating fingers extremely tiring. Furthermore, the amount of steam required for finishing varies depending on the fiber to be ironed, and the operator has to increase or decrease the amount of steam by adjusting the operating speed and spacing of the steam button 43. Therefore, it is very difficult to stably supply the required amount of steam to the fibers, resulting in a problem that the ironing finish υ of the fibers deteriorates.

Therefore, the present invention provides an electric water supply device as a means for sending the water in the tank to the vaporization chamber, and also drives the lining at predetermined intervals to send the water in the tank to the vaporization chamber. The first objective is to eliminate the need for the operating force of repeatedly pressing down on the steam button, thereby improving operability when spewing steam.

The second purpose is to prevent hot water from spewing out from the base and make it safe to use by stabilizing the water supply amount and water supply interval of the reservoir from which steam is spouted.

A third purpose is to further improve usability by allowing steam to be continuously ejected at predetermined intervals without having to press a steam button each time steam is ejected.

Means for solving the problem and in order to achieve the above first objective, the present invention provides the following:
An electric water supply device that supplies water in the tank to the vaporization chamber is driven at predetermined intervals.

Further, in order to achieve the second object, the present invention is such that the drive interval of the electric water supply device that supplies water in the tank to the vaporization chamber is controlled by a timer means.

Furthermore, in order to achieve the third object, the present invention provides that when the steam button that excites the drive of the electric water supply device is operated,
The water supply device continues to be driven at predetermined intervals.

Function The steam iron of the present invention with the above configuration eliminates the need for operating force to push down the steam button protruding from the handle against the spring force each time steam is jetted, improving operability when steam is jetted.

Furthermore, by controlling the drive interval of the electric water supply device that supplies water in the tank to the vaporization chamber by means of a timer,
Since the amount of water that generates steam and the interval between water supplies are stable, there is no need to oversupply water, making it possible to use the product safely without boiling water gushing out from the base.

In addition, when the steam button that excites the electric water supply device is operated, the electric water supply device continues to drive at a predetermined interval, so steam can be ejected continuously without having to press the steam button every time steam is ejected. This will further improve usability.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIG. 1, reference numeral 11 denotes a base having a heater 11a, and a vaporizing chamber 12 is integrally constructed with this base. 13 is a vaporization chamber lid that covers the vaporization chamber 12. 14 is the base 11 above
This is a heat insulating board placed above the 16 to the main body of the water conduit,
Reference numeral 16 denotes a water conduit main body B, which is joined to the water conduit A1es by heat welding or the like to form a water conduit 17. Reference numeral 18 denotes an elastic connecting pankin attached around the entrance 17a of the water conduit 17, and its upper surface is in close contact with the tank outlet 19a formed at the bottom of the tank 19, thereby communicating the tank 19 and the water conduit 17. 20 is the tank outlet 19a at the bottom of the tank
When the removable tank 19 is attached, it is pushed open by the lifting part 21 formed by the water conduit main body B16, allowing water in the tank 19 to flow into the water conduit 17.

A drip nozzle 22 is provided at the outlet of the water conduit 17, and is connected to the opening 1 of the vaporization chamber lid 13 via a nozzle pankin 23.
The water conduit 17 and the vaporization chamber 12 are communicated through the channel 3a.

Reference numeral 24 denotes a ball valve, which is freely movable in a hollow portion 26 that forms a part of the water conduit 17 of the water conduit main body A16. 2e
is a plug provided on the lower surface of the headrace body B16, and is a plug provided on the lower surface of the headrace body B16,
7. 27 is also a ball valve, and is set via a biasing spring 29 in a hollow portion 28 that forms a part of the waterway 17 of the waterway main body A15, and faces the lower end of the pump device 3o. This pump device 3o is built in a cylinder 31 configured in the water conduit 17. , , 32 is a motorized device configured with an electromagnetic lens installed above the pump device 30, and the motorized device support stand 3. ．． It is constructed integrally with the cylinder 31 via 3. Normally, when no current flows through the electric device 32, the spring 34 urges the pump device 3o upward, and when current flows, the electric device 32 overcomes the force of the spring 34 and pumps the pump device 3o. The device 3o is pushed downward, and the water conduit 17 is opened and closed by the ball valve 27.

In such a configuration, to explain the flow of water, water in the tank 19 enters the entrance 17a of the water conduit 17 through the connecting gasket 18, pushes the ball valve 24 with water pressure, and flows into the water conduit main body A1s. It flows into the cylinder part 33 formed in one part. When current is applied to the pump device 30, the lower end of the pump device 30 pushes down the ball valve 27, so water flows from the drip nozzle 22 into the vaporization chamber 12 via the ball valve 27.

Next, the operation of the pump device 3o will be explained.

Normally, when no current is flowing through the electric device 32, the spring 34
is pushing the pump device 3o upward, so the lower end of the pump device cannot push the ball valve 27, and the ball valve 27 blocks the water conduit 17, resulting in a "dry" state. .

Next, when the switch 36 is pressed to energize the electric device 32, the electric device 32 is excited, and the pump device 30 is pushed down by overcoming the force of the spring 32, and the lower end of the pump device 3o pushes the ball valve 27, so that the tank 19 The water inside is
Due to the water head pressure, as mentioned above, the drip nozzle 22
The flow rate is regulated and supplied to the vaporization chamber 12, where normal steam is generated. - When a large amount of steam is occasionally required, for example, as shown in FIG. 2, by pressing the steam increase switch 36 once, the electromagnetic solenoid is energized by an electronic circuit (not shown) or the like. By configuring it to automatically turn 0N10FF at predetermined intervals, the electromagnetic renoids are energized and de-energized cyclically, so the pump device 30 repeatedly moves up and down, vaporizing a large amount of water through the dripping nozzle 22. It can be forcibly supplied to chamber 12. As a result, "increased steam" is obtained.

Furthermore, when the switch 36 for increasing steam is pressed,
Energization to the electromagnetic solenoid is fixed to ON or OFF,
The ejection of increased steam stops. In this way, in order to eject the booster steam, it is only necessary to press the switch 36 for the booster steam, and there is no need for a large operating force or amount of depression, and the operability is greatly improved.

In addition, by configuring the electric device 32 to be driven by an electronic circuit or the like in a stable cycle of 0N10FF,
Since the speed and interval of steam jetting do not differ depending on the operator, there is no variation in the amount of steam, and the electric device 32 is driven in advance so that the amount of water commensurate with the vaporization capacity of the base vaporization chamber 1 is fed. ○N1
By having a configuration in which the period of 0 F F is determined,
There is no problem of hot water spewing out from the base 11 due to water being supplied that exceeds the vaporization capacity of the vaporization chamber 1, and safety can be improved.

FIG. 3 is a timing chart showing another embodiment. When the above-mentioned steam increase switch is pressed, the electric device is automatically driven by an electronic circuit or the like to 0N10FF L,
, automatically turns on after operating a predetermined number of times or for a predetermined time.
Alternatively, it is configured to stop when turned OFF. In this case, there is no need to press the additional steam switch again to stop the ejection of increased steam, and the operability is further improved. Although Fig. 3 shows an example in which the electric device is driven by 0N10FF multiple times, it is also possible to use only -0N10FF, and instead of regulating the drive by the number of times, it is stopped after driving for a predetermined time. In short, after pressing the switch for increasing steam once, the electric device automatically stops and the ejection of steam for increasing steam stops without pressing the switch for increasing steam again. It's fine as long as it's something you do.

Fig. 4 is a timing chart showing still another embodiment, in which when the above-mentioned switch for increasing steam is pressed, the electric device is automatically driven by an electronic circuit, etc.
L, after operating a predetermined number of times or for a predetermined time, automatically turns OFF L, and after this OFF state continues for a predetermined time, - The electric device is configured to repeat 0N10FFL, a predetermined number of times or a predetermined time of operation. This is what I did. In this case, since there is a cycle in which the electric device is turned off for a predetermined period of time, while the electric device is at rest,
The temperature of the base, which has decreased due to the evaporation of water, recovers to the predetermined temperature, making it possible to eject an increased amount of steam while the base temperature is always high. This makes it possible to significantly improve the finishing effect during ironing.

FIG. 5 is a timing chart showing still another embodiment. Only while the above-mentioned steam increase switch is pressed, the first drive of the electric device is automatically turned off by an electronic circuit or the like.
N10FF L, if you stop pressing the steam increase switch, the drive of the electric device will immediately stop turning ON or OFF. In this case, an increased amount of steam can be obtained only when the operator needs it, there is no needless ejection of steam, and water in the tank can be prevented from being wasted. Therefore, the number of times water is supplied into the tank is reduced, and ironing efficiency can be improved.

In the above embodiment, a configuration was shown in which the pump device that moves up and down is driven by an electromagnetic solenoid, but a configuration combining a motor and a diaphragm, or a spring and a cam, etc. may also be used. Any device that can be driven at intervals of

Effects of the Invention As described above, the present invention improves the operability of the steam jetting reservoir by driving the electric water supply device that supplies water in the tank to the vaporization chamber at predetermined intervals. Furthermore, in the present invention, by controlling the driving interval of the electric water supply device using a timer means, the supply amount and water supply interval of water for generating steam are stabilized, so that supply of water exceeding the vaporization capacity of the base can be prevented. , there is no spouting of hot water from the base, and you can get a safe iron.

Furthermore, in the present invention, when the steam button that excites the drive of the electric water supply device is operated, the device continues to drive in a predetermined interval, so steam can be ejected without pressing the steam button every time steam is ejected. If it can be obtained continuously, the usability can be further improved. In addition, the electric water supply device-V drive pattern allows steam to be ejected even when the base surface is high in temperature.
It is also possible to improve the wrinkle smoothing effect of ironing, prevent wastage of water in the tank, and improve ironing work efficiency.
