Description

[Detailed Description of the Invention] A. Purpose of the Invention a. Industrial Field of Application The present invention relates to a steam ironing device that can eject steam from the bottom, and mainly consists of a commercial iron body and a water tank. This invention relates to an improvement of a separate steam ironing device.

B. Prior Art Conventionally, there have been steam ironing devices, mainly for commercial use, which have a separate iron body and a water tank, and are divided into boiler type and drip type. The boiler type is one in which steam is generated in a boiler that also serves as a tank or a separate boiler, and the steam is guided to the iron body via a hose and ejected from the steam port.

In addition, the drip type means that the water tank and the iron body are connected through a hose with pulp, and by opening and closing the pulp, the water in the tank is dripped at room temperature into the heated vaporization chamber of the iron body, where it is vaporized and generated. Steam is ejected from the steam port.

Problems to be solved by the invention Among the above-mentioned conventional steam ironing devices, boiler-type ones are:
Even if the iron itself reaches the desired set temperature with its built-in heater, it takes 10 to 20 minutes for the boiler to generate the desired steam, so ironing cannot be done during that time.

Further, even when the amount of work is small, it is necessary to generate at least a certain minimum amount of steam necessary for the boiler, and excess steam must be discharged, which is uneconomical.

Furthermore, there is a drawback that there is a risk of the boiler exploding due to steam pressure if the safety valve malfunctions or due to carelessness.

On the other hand, the drip type iron solves the drawbacks of the boiler type steam iron. However, since steam is generated by vaporizing water in a vaporization chamber within the iron body, a considerable amount of heat is lost as heat of vaporization. In other words, the temperature of the vaporization chamber inside the iron body is heated by the heater and reaches a maximum of 2.
Although the temperature is about 10℃, there is no supply from the tank.
The room temperature water that is dripped is usually around 20 degrees Celsius on average per year.
The temperature difference is extremely large. Therefore, when steam is continuously discharged, the temperature of the vaporizing chamber decreases significantly due to the heat of vaporization, and accordingly, the temperature of the iron sole plate decreases, and the temperature of the ejected steam also decreases.

Moreover, when the temperature of the vaporization chamber drops to about 110° C. or lower, the water that flows down the cylinder cannot be completely converted into steam, and a drain phenomenon occurs in which water droplets mix with the steam and are ejected from the steam port. This drain phenomenon causes smearing on the clothes being ironed.

In particular, in cases where the ironing temperature cannot be set high, such as with synthetic clothing, the temperature in the vaporization chamber will naturally not be high, and the temperature will drop by approximately 110°C due to the heat of vaporization.
Below K, it is faster to reach K, and the drain phenomenon is more likely to occur.
There are many problems such as.

The present invention aims to solve the drawbacks and problems of the conventional boiler type, drip type, etc. steam ironing devices. In other words, the purpose is to eliminate the waiting time for steam generation, unlike boiler-type irons, so that work can be started at the same time as the iron itself heats up, and it eliminates the possibility of generating more steam than necessary or risking an explosion due to steam pressure. The goal is to completely eliminate it.

Furthermore, unlike the conventional drip type, it reduces the temperature drop in the vaporization chamber due to the heat of vaporization, prevents the bottom plate temperature and steam temperature from dropping, and prevents the occurrence of the drain phenomenon and prevents stains on clothes, etc. In particular, the purpose is to allow ironing of synthetic fibers at "low temperatures" without any problems.

Arrangement of the Invention A Means for Solving Problems The steam ironing device of the present invention has a steam ironing device in which a water tank +1+ and a pump (2) are placed outside the iron body (3), and each is connected to the water tank +1+ by a hose +41+51. In the ironing device, between the pump (2) and the iron body (3), there is a coiled vibrator (7), a heating means (8) for heating the water inside the vibrator, and a device that maintains the water temperature at about 90°CK. In addition to providing a temperature control means (9) with a fuse, a coiled pipe (
7) and the iron body (3), the hose (5) is made to have heat retention properties.

In the above configuration, it is preferable that the water tanker (11) be of a portable cartridge type and set in an inverted position so that the water supply cap (10) on the head is at the bottom.

The pump (2) may be a rotary pump such as a gear bomb, a reciprocating pump, or other pumps. Coiled Vig (
7) is often made of copper or other metal, for example;
Further, as the heating means (8), it is preferable to use a rod-shaped electric heater or a high frequency heating means. Coiled pipe (7)

/ Mr. Ichiguchi When a rod-shaped electric heater is used as the melting means (8), the heater and the coiled pipe (7) are made of a material with thermal conductivity and heat storage properties, such as lead ( 11) or aluminum to be cast together and integrally formed. Heat-retaining hose (6)
For example, the temperature control means (9) is made of silicone rubber, and the temperature control means (9) is, for example, a PuMo cut, and its sensing part is set to heat and keep the water temperature at about 90'C. The current is automatically turned on to prevent the temperature from heating up to a boiling point or dropping below 90°C.
・It is turned off.

In the figure, jl2) is a water storage chamber that temporarily stores water discharged from the water tank (1) and supplies it to the next pump (2) in a fixed amount. (13) is a hose hanging strut, which connects the hose (5) between the heating means (8) and the iron body (3).
) to prevent the hose (5) from getting in the way during work. (l4) is an electromagnetic valve that supplies and stops hot water from the hose (5) to the vaporization chamber (15) of the iron body (3). (It is a micro switch installed in the grip part (6) of the iron body (3).
When this is turned on, the pump (2) rotates and the electromagnetic pulp (14) opens. (17) is the wiring code, AC code 12! From oj to pump (2), heating means (8), temperature control means (9), solenoid valve 04),
Each is wired between the microswitches (I6). In addition, the hose (
5) It is preferable to house the wiring cord +17) in one tube (1~.Also, even if this tube θ8) is made to have heat retention properties, the internal hose (6) is still heat insulated. It is better to use natural materials.

(21) is the U heater of the iron body, (22 is the bottom plate, (
C) is a steam vent, an example is a water tank stand, and a saw is a filter. In addition, two or more coiled pipes (7) may be heated by one heating means (8), and two or more irons may be used.

b Function When using the present invention, first fill the water tank ([) with water, place it upside down on the tank stand (241, and connect the AC cord 0) to the power outlet, and then connect the iron body ( 3) is set to the desired temperature.゛Thus, the heating means +8+K current is passed through the wiring cord (17) and heated, and another wiring cord (the heater (2) 1 of the iron body (3) is heated through the 1st wire). ,
The spider plate (22) and the vaporization chamber (15) are also heated.

The iron body (3) then adjusts to the desired set temperature, e.g.
When the temperature reaches about 210°C, the other heating means (8) has already heated the water in the coiled pipe (7) to about 90°C.
It is ready to be heated to 0°C. Then, turn on the microswitch (16) of the iron body (3) to rotate the pump (2) and open the electromagnetic valve (14). As a result, the room temperature water in the water tank (11) passes through the water storage chamber f12 pump (2), coiled pipe (7), heat retaining hose (5), electromagnetic valve α, etc., and then evaporates into the iron body (3). It is supplied to the chamber (15). On the way,
Since the coiled pipe (7) is wound around the outer circumference of the heating means (8), room temperature water is heated there to approximately 90°C, and the approximately 90°C hot water is passed through a heat-retaining hose (5). ) is supplied to the vaporization chamber (I5) while being kept warm.

Therefore, in the vaporization chamber (15), unlike conventional water at room temperature of about 20°C, which is dripped and vaporized, hot water at nearly 90°C is dripped and vaporized, so the temperature drop due to vaporization is significantly reduced. Decrease. That is, in the vaporization chamber (I5) for steam generation,
The amount of heat lost due to vaporization is reduced, so the vaporization chamber (
15) and the accompanying temperature drop of the iron bottom plate and the ejected steam are suppressed.

Furthermore, even if the set temperature of the iron body (3) is set to "low temperature" of approximately 120°CK, the same setting as above can be applied.
Because of the dripping and vaporization of hot water near 0°C, the temperature of the vaporization chamber (16) does not decrease much, and the temperature does not easily drop below about 110°C. Therefore, the drain phenomenon in which the water dripped into the vaporization chamber cannot completely turn into steam and is spouted out from the steam port together with the steam as water droplets is less likely to occur. That is, in the present invention, even if the set temperature is set to 120°C, the temperature of the vaporization chamber (15) is unlikely to drop below about 110°C due to the heat of vaporization, and the drain phenomenon is unlikely to occur, thus preventing stains on clothes, etc. can.

Embodiment C shown in Fig. 1 uses a rod-shaped electric heater as the heating means (8), and a coiled pipe (7) is cast into one body with lead (11), which has thermal conductivity and heat storage properties. A silicone rubber hose is used as the heat retaining hose (5). Figures 2 and 3 show the temperature difference between the steam ironing device of this example and the conventional drip type steam ironing device.
This is a graph of the figure. Figure 2 shows the set temperature of the iron, and therefore the initial temperature of the vaporizing chamber (!5), is 210'C. Figure 3 shows the set temperature of the iron and the initial temperature of the vaporizing chamber (15).
In each case, the initial temperature of It was set to 20 cc per minute in the operating state. In the figure, the solid line shows the humidity of the iron in the example (depending on the iron), and the dotted line shows the temperature of the conventional iron.Please note that the actual usage conditions are slightly different due to measurement reasons, and are not recommended for long-term continuous use without interruption. be.

Based on this measurement, the temperature of the vaporization chamber (15) was 110'.
If the temperature is below C, set the iron temperature to 210'C.
In this case, the conventional ironing device uses a steam iron for 5 minutes after the start of use, whereas the ironing device of the embodiment takes 9 minutes, which is 1.8 times higher and 80% higher. Furthermore, when the set temperature is 150°C, the conventional ironing device waits for 1 minute and 20 seconds, while the ironing device of the example takes 2 minutes and 20 seconds, which is 75% A and 1.75 times the Ab. Met.

Next, when the set temperature is 210°C, the steam temperature at the steam port (23) becomes 110°C or less in about 10 minutes in the conventional ironing device, whereas in the iron of the embodiment With the ironing device, it takes 15 minutes, which is 50% higher and 1.5 times longer, and when the temperature is set at 150℃, the conventional ironing device takes 3 minutes and 4 minutes.
0 seconds later, while in the example it is 63% higher and 13 seconds later.
It was 6 minutes after 63 times.

The above measurement results show that the ironing device of the example has less temperature drop than the conventional ironing device, and is less likely to cause the drain phenomenon! Effects of the Invention As is clear from the above, according to the present invention, firstly, the waiting time for steam generation can be eliminated, and the waste of steam can also be eliminated, as well as the danger. . In other words, in conventional boiler-type steam ironing devices, even if the iron body reaches the desired set temperature, it takes 10 to 30 minutes for the boiler to generate the desired steam.
20 minutes? In short, ironing cannot be done during that time. Furthermore, even if the amount of work is small, the boiler must generate a minimum amount of steam, which is uneconomical.

Furthermore, there was a risk that the boiler would be exposed to light due to steam pressure. However, in the present invention, it is sufficient that the boiler does not generate steam and the heating means simply heats the water passing outside the boiler to about 90'C. Therefore, when the iron body reaches the desired set temperature, the heating means has already reached a temperature at which it can heat the water to about 90° C., so there is no waiting time.

In addition, since the steam is generated within the vaporization chamber of the iron, there is no need to generate excess steam, and there is no need to discharge excess steam, making it economical and eliminating danger.

Second, in the conventional drip-type steam ironing device, water at room temperature is supplied and dripped into the vaporization chamber for vaporization, so the temperature difference is large and a considerable amount of heat is lost due to the heat of vaporization, resulting in a significant temperature drop. Therefore, the temperature of the bottom plate of the iron and the ejected steam decreases, and if the temperature of the vaporizing chamber is still below about 110°C, the water cannot completely turn into steam, and a drain phenomenon occurs in which water droplets are ejected along with the steam. Clothes, etc. were smeared. This tendency was especially strong when the "low temperature" setting was used. On the other hand, in the present invention, water is heated to approximately 90°C via a heating means and then supplied to the vaporization chamber and dripped, so it is possible to suppress the temperature drop of the iron bottom plate, the jetted steam, and the temperature of the vaporization chamber. can. Therefore, ironing can be performed efficiently as a steam iron, and the drain phenomenon is less likely to occur, and staining of clothes, etc. can be prevented. In particular, even when the ironing temperature must be set to a "low temperature" K, such as with synthetic fibers, the steam ironing device of the present invention is unlikely to cause a drain phenomenon, and ironing can be done at a lower temperature than conventional methods. be.
