DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water container for a steam iron for supplying water for generating steam to a steam iron for wrinkling clothes or the like.

[0002]

2. Description of the Related Art Generally, tap water is used as water for generating steam in a steam iron. However, if tap water is used as it is, after water is vaporized in a vaporization chamber, calcium and sodium contained in the water are removed. The inorganic substance remains as an evaporation residue and gradually accumulates as water scale in the vaporization chamber and in the steam passage from the vaporization chamber to the steam vent. Longer use of the iron will eventually block the narrow part of the steam corridor, hindering steam eruption.

In order to solve such a problem, for example, as described in Japanese Patent Application Laid-Open No. 61-179194, a steam iron provided with a scale binding inhibitor has been considered. Hereinafter, the configuration will be described with reference to FIG.

As shown in the figure, a tank 2 for storing water is provided above a base 1 heated by a heater (not shown).
The water in the tank 2 enters the vaporization chamber 5 from the outflow portion 4 opened and closed by the opening / closing rod 3, turns into steam, passes through the steam passage 6, and blows out from the steam hole 1 a. The anti-scale agent 7 is made of a molded product such as an inhibitor or a chelating agent, and is contained in the tank 2 and dissolved in the water in the tank 2.

Here, when the worker generates steam and performs ironing work, when water is poured into the tank 2,
The water in which the descaling agent 7 is dissolved passes through the outflow portion 4,
It enters the vaporization chamber 5 of the base 1 and is vaporized to become steam. At this time, the mechanical strength of the scale formed in the vaporization chamber 5 is reduced by the action of the scale-binding inhibitor 7 dissolved in water, and the scale is less likely to adhere to the scale. As a result, the scale is discharged from the vaporization chamber 5 to the outside through the steam passage 6, and it is possible to prevent the scale from adhering and accumulating on the vaporization chamber 5 and the steam passage 6.

[0006]

In such a conventional construction, if the scale 2 is contained in the tank 2, the scale is prevented from adhering to the vaporization chamber 5 and the steam passage 6. However, if the scale 2 is not stored in the tank 2, there is a problem that the scale cannot be suppressed from being deposited.

When the anti-scale agent 7 is stored in the tank 2, the water in which the anti-scale agent 7 is dissolved
In order to discharge the scale with steam out of the iron,
While it can prevent accumulation in the vaporization chamber and in the steam passage from this vaporization chamber to the steam vent, there is a problem in that since the discharged scale is large, it adheres to the clothing to be ironed and contaminates the clothing. there were.

The present invention solves the above-mentioned conventional problems, and suppresses the adhesion of scale to the vaporization chamber and the steam passage of a steam iron having no means for preventing scale connection, thereby allowing stable steam to be ejected. At the same time, it aims at miniaturizing the scale to reduce the adhesion to clothing.

According to the present invention, in order to attain the above object, a scale binding preventing means is provided in a container having a pouring / draining section and a water storing section, and the scale binding preventing means comprises a phosphate compound. It is configured to be contained in the water in the container.

[0010] Thus, even in a steam iron not provided with means for preventing scale from binding, it is possible to prevent the scale from adhering and accumulating in the vaporizing chamber and the steam passage and to spout stable steam, and to reduce the scale of the scale. As a result, adhesion to clothing can be reduced.

[0020]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) As shown in FIG.
Is used to pour water into the water tank (not shown) of the steam iron when performing ironing work. Pour water from a water tap, etc., or pour water into the water tank of the steam iron. It has a drainage section 9 and a water storage section 10 for storing water entered from the pouring and draining section 9. This container 8
Inside, a scale-preventing means 12 accommodated in a water-permeable case 11 formed of a resin molded product is disposed at the bottom of the water storage unit 10.

The scale-preventing means 12 is for preventing the scale from adhering and accumulating. Specifically, a phosphate compound such as calcium metaphosphate is formed into a solid, pellet, or granule and stored in the water-permeable case 11. are doing. The water-permeable case 11 is in a state in which the scale binding preventing means 12 is stored.
The upper surface is sealed with a sealing net 13, and has a small hole 14 on the side that serves both as air bleeding and water inflow and outflow, and is fixed to a screw hole provided at the bottom of the container 8 with a fixing screw 15.

Next, means for preventing scale binding (phosphate compound)
Twelve manufacturing methods and granulated products will be described. In this example, calcium dihydrogen phosphate was used as a raw material of calcium metaphosphate. This is first kneaded well with water. In this case, an organic substance such as methylcellulose or an inorganic substance such as water glass may be used as a binder in addition to water. After well kneading, the mixture was granulated by an extrusion granulator, and then calcined at 250 ° C. or higher, in this example, 800 ° C.

[0024] Calcium metaphosphate is formed by the chemical reaction during the firing. After preparing calcium metaphosphate powder, granulation may be performed using a binder such as ethyl cellulose or an acrylic dispersion. In addition, as a raw material, in addition to calcium dihydrogen phosphate, calcium metaphosphate can be prepared as long as it contains a phosphate group and calcium.

Since the solubility of calcium metaphosphate in water is very small, a small amount of metaphosphoric acid can be added to water by adjusting the particle size to an appropriate value. In this example, a granulated product of calcium metaphosphate having a diameter of about 3 mm was used. When a granulated product such as a solid, pellet, or granule is used as the scale binding preventing means (phosphate compound) 12, the dissolution characteristics depending on the surface area can be adjusted, and the configuration of the water-permeable case 11 can be simplified.

The operation of the above construction will be described. When the worker performs ironing, water is injected from the pouring / draining section 9 of the container 8 to inject water for generating steam into the water tank. Water penetrates into 10 and the inside of water-permeable case 11 is also immersed in water through sealing net 13 and small hole 14.

The scale binding preventing means 12 includes the water-permeable case 1
1 is dissolved in the water in the water storage unit 1, and the water dissolved by the scale-restraining means 12 passes through the sealing net 13 and the small holes 14.
Replaced with water in Then, by putting this water into the water tank of the iron that generates steam, it is possible to prevent scale from adhering and accumulating.

Generally, the scale that accumulates in the vaporization chamber or the steam passage of the steam iron is one in which inorganic components such as calcium and sodium contained in the water remain due to evaporation of the water. In particular, since calcium carbonate and the like have very low solubility in water, once generated residue is almost insoluble in water dropped into the vaporization chamber next due to steam generation, so the residue is deposited one after another and huge. It becomes a crystal.
In this way, the scale locally deposited in the vaporization chamber blocks the steam passage and the like, and hinders the stable ejection of steam.

The phosphate compound constituting the scale binding preventing means 12 as a means for suppressing scale buildup enters crystals formed when the inorganic components in the water are evaporated and left. If phosphorus of another component enters into a crystal of the same component, the crystal structure becomes distorted and cannot grow. As a result, the scale is refined, the scale is dispersed in the vaporization chamber, and part of the scale is discharged to the outside together with steam. Therefore, the accumulation in the vaporization chamber is suppressed, and the steam can be stably blown out over a long period of time without being blocked by the steam passage.

A metaphosphate is used as a phosphate compound. The metaphosphate has two phosphorus atoms in the molecule and binds so as to sandwich calcium and the like inside the scale, so that the scale is particularly high among the phosphate compounds. Is obtained.

Further, since the descaling prevention means 12 is housed in the water-permeable case 11, the contact area in contact with the water in the container 8 can be increased, and the descaling prevention means 12 can be dissolved in water in a short time. It is possible to prevent the scale from adhering and accumulating in the vaporization chamber and the steam passage, and furthermore, it is possible to supply a stable steam without the broken pieces of the scale preventing means 12 entering the water tank of the iron. .

In addition, the scale binding preventing means 12 is provided in the water storage section 1.
Since the water is disposed at the bottom of the water storage unit 10, the water supplied from the pouring / draining unit 9 is stored in the water storage unit 10 without passing through the scale coupling prevention unit 12, so that the water is filled in the water storage unit 10 in a short time. In addition, even if the amount of water in the container 8 is small, the water scale in the container 8 may be small, since the scale preventing means 12 can be submerged and dissolved. Ironing can be made more efficient.

The container 8 is partially or entirely formed to be transparent or translucent, and is provided with a water volume scale 16 to indicate, for example, a full water level, a water volume, etc., so that the water can be combined with excess water more than necessary. Since the water in which the prevention means 12 is dissolved is not prepared, the scale connection prevention means 12 can be used effectively, and the effect of suppressing the adhesion of scale can be maintained for a long time.

In this embodiment, the water-permeable case 11
Is made of a resin molded product. However, the same operation and effect can be obtained by using a metal net-like or mesh-like gauze or cloth.

The lid 27 is disposed so as to open and close the pouring / draining section 25 freely.

The upper and lower portions of the water-permeable case 28 are sealed by a sealing net 29 in a state in which the scale-preventing means 12 formed of calcium metaphosphate in a pellet form is housed. The water-permeable case 28 has a floating body 30 attached to a part of the water-permeable case 28 so as not to sink below the water surface, and moves in the water storage section 26 in response to a change in the amount of water. Other configurations are the same as those in the first embodiment.

The operation of the above construction will now be described. When the worker performs ironing, the pouring / draining part 25 of the container 24 is used to inject water for generating steam into the water tank.
When water is poured from the water, the water enters the water-permeable case 28 and accumulates in the water storage part 26. Then, the pouring and draining section 2 is
By closing the container 5 and shaking the container 24 up, down, left and right, there is no outflow of water outside the container 24, and the movement of the water in the container 24 can efficiently dissolve the scale binding preventing means 12 in the water, Ironing can be performed efficiently.

Since the scale-prevention means 12 is arranged so as to be able to move freely in the water storage section 26 in response to a change in the amount of water, the scale-prevention means 12 is not used when water is injected.
