Background
The electric steam iron can reduce the labor intensity, and the operators who do the ironing operation from the front need to spray water by the sprayer to spray the steam generated inside or outside the iron to the clothes or the sewed articles, etc., after the heater wire in the iron body heats up, the iron bottom plate can be heated and put on the wrinkles of the sewed articles of clothes for ironing, and the electric steam iron is widely applied to the ironing operation.
In a sewing factory or a laundry room, etc., where a large amount of steam is required, a steam iron is used, a large amount of steam is generated in a boiler, and then the generated steam is supplied to each iron used in an ironing work, and a worker uses the steam for the ironing work. In this case, a sufficient amount of steam can be continuously supplied to each iron by generating a large amount of steam using the boiler, but it is necessary to always generate more steam than the amount of steam required for each iron, and even if a steam ironing operation is performed using only one iron, the boiler needs to be always on, which increases the operating cost of the boiler, which is a disadvantage. Further, steam supply equipment for supplying steam generated in the boiler to each iron is expensive, has a large steam loss, and sometimes discharges water after liquefaction of the steam.
In order to overcome the above disadvantage that the cost is high when the boiler is used, the iron body is heated after being filled with water to generate steam, but in the steam electric iron having the steam generating chamber in the form of a water tank, the steam generated from the water tank is easily liquefied when being sprayed from the iron, and it is difficult to spray steam in a completely vaporized state, and the amount of generated steam is not sufficient, and it is difficult to continuously supply steam, which have been pointed out as problems.
In addition, in order to overcome the disadvantage that the cost becomes high when a boiler is used, there is an electric steam iron in which a water tank filled with water is provided outside the iron body, and a steam generation chamber in the form of the water tank heats water supplied to the water tank to generate steam. However, the steam generated in the steam generating chamber of the product is liquefied until the steam is sprayed, and the water spraying phenomenon is difficult to avoid. Moreover, the amount of steam is not sufficient, and it is difficult to continuously supply steam.
In addition, the water supply temperature of the water tank is low, time is needed for heating the steam generation chamber to the steam generation temperature, and time difference occurs due to the fact that the steam generation chamber needs to be heated.

Referring to fig. 11 and 12, the electric steam iron of the present invention generally comprises, from the external appearance thereof, a soleplate 1, a preheating and steam generating part (fig. 6) and a steam passage part (fig. 8) capable of effectively generating steam, a body case 12 surrounding the soleplate 1, an anti-scalding plate 18 for preventing the body case 12 from scalding the skin of a user, a handle 10 of the iron, a steam discharge button switch 14, and a water supply part 17 into which external water is supplied through a silicone tube. The burn protection plate 18 is insulated from the iron body case 12 by an insulation 19.
Referring to fig. 13, the electric steam iron of the present invention of fig. 13 includes a soleplate 1 at a lower portion of the iron, and a steam guide soleplate cover 2 provided to cover a front portion of the soleplate 1. The electric steam iron of the present invention comprises a steam passage part 3 provided to cover the rear part of the soleplate 1, a preheating and steam generating part 4 in which a heating element (heater wire) is built or fixed to preheat water supplied from the inside and complete the vaporization, and a cover plate 5 covering the preheating and steam generating part 4 and receiving water supplied from the outside to the preheating and steam generating part 4. The steam passage part 3, the preheating and steam generating part 4 and the cover plate 5 are assembled to cover the rear part of the soleplate 1. On the other hand, although not shown in fig. 13, a heating element (heater wire) (70 in fig. 7a) is incorporated or fixed in the preheating and steam generating section 4 and integrated, and both ends of the heating element (heater wire) 70 are a first power supply contact portion 72 and a second power supply contact portion 74, which are connected to the power supply cable 7, respectively. On the other hand, the cover 5 is provided with a water supply inlet 64, and the water supply inlet 64 is connected to a water supply port of a water pump motor 8 for pumping water from an external water tank or a water source through a water supply pipe 6 (hose). The pump water inlet 81 of the water pump motor 8 is connected to an external water tank or water source through a silicone tube 82. An action control box 11 is arranged around the water pump motor 8, and a control Part (PCB)9 for controlling the action of the iron is arranged in the action control box 11, so that the water supply amount and the temperature of the iron can be controlled. Reference numeral 10 denotes a handle, 14 denotes a steam discharge button switch, and 18 denotes an anti-scald plate.
Hereinafter, a steam generating method for efficiently generating stable steam in the electric steam iron of the present invention will be described.
As for the preheating and steam generating part to which the present invention is applied, which will be described in detail later with reference to fig. 5 to 7b, the stable steam generating method of the present invention heats the supply water supplied from the external water tank or water source to the preheating and steam generating part in the iron body under the control of the power control Part (PCB) (9 of fig. 13) and generates steam, and the preheating and steam generating part (fig. 6) embeds or fixes a heating element (heater wire) 70, is integrated with the heating plate (fig. 7a), and is sealed, and completes the preheating of the supply water and the primary and secondary steam generation on the same plane.
As shown in fig. 6, the preheating and steam generating part of the present invention includes: a high-temperature preheating and primary steam generation chamber F for preheating and primary steam generation after water supply is obtained from the outside; and a secondary steam generating chamber G for secondarily vaporizing the preheated water and the primary steam supplied from the high-temperature preheating and primary steam generating chamber F. Therefore, the contact time and contact area in the preheating and steam generating part are increased, and stable steam can be generated. Further, the lattice-type gap walls 40 forming a plurality of gaps between the high-temperature preheating and primary steam generating chamber F and the secondary steam generating chamber G are further included, so that the secondary vaporization process of the preheated water and the primary steam supplied to the high-temperature preheating and primary steam generating chamber F is faster.
The preheating and the primary steam generation of the preheating and steam generation part are separated from the secondary steam generation and are finished on the same plane space, and the stable steam generation method can be finished by water quantity control and temperature control, so that more sufficient and stable steam can be generated. Such a water amount control and temperature control method employed in the present invention will be described in detail with reference to fig. 9 and 10.
Fig. 9 is a block diagram illustrating the concept of the control operation of the electric steam iron according to the present invention. In fig. 9, the control unit controls the opening and closing of the water pump switch to control the opening time of the water pump motor, thereby controlling the amount of water supplied. On one hand, the water pump motor can be controlled according to the supplied water quantity sensed by the supplied water quantity sensor; on the other hand, although not shown in the drawings, the supply of water from the external water tank to the iron can be realized by opening and closing a valve.
In fig. 9, the control unit includes a temperature sensor (for example, thermistor) for measuring the temperature inside the steam generating chamber, and the embedded heater wire (heating element) is heated by the power supply, and the power switch controls the on and off of the power supply, thereby controlling the heating operation of the heater wire embedded in the preheating and steam generating unit or fixed to the outer bottom surface of the preheating and steam generating unit constituting the mechanism of the steam generating chamber inside the machine body. The power switch includes a semiconductor logic circuit soft switch, and as will be appreciated by those skilled in the art, the description thereof is omitted here.
Fig. 10 is a flowchart for explaining a steam generating operation of the electric steam iron according to the present invention. Referring to fig. 10, in the steam iron of the present invention, although not shown in the drawing, after power-up, the water pump motor (8 in fig. 13) in the operation control box (11 in fig. 13) is started under the control of the power control unit (9 in fig. 13), that is, the water pump is started at step S100. Water supplied from an external water tank or a water source (not shown) is supplied to a preheating and steam generating part (fig. 6) inside the iron through a water supply pipe (6 of fig. 13), and the water is preheated and heated to become steam.
In this case, the method further includes a step S110 of controlling the water supply amount of the preheating and steam generating part by the water pump motor, and detecting the required water supply amount. If the water amount is not the amount of water required to be supplied in the step S110, the water pump motor control step S120 is performed to control the opening of the water pump motor (8 in fig. 13) in the operation control box (11 in fig. 13) to adjust the water supply amount. The amount of water supplied through the water supply pipe (6 of fig. 13) is 10ml to 30ml per minute, and the optimum test results are obtained when passing through the preheating and steam generating part, and the amount of water can be precisely adjusted by controlling the water pump through the PCB.
These practitioners of the pump motor control will not understand and will not be described in detail herein, far from the core of the present invention.
In the stage S130, the preheating and primary steam generation chamber performs preheating and primary steam generation, and then sends the amount of supplied water to the secondary steam generation chamber, because the temperature of the supplied water is low. The reason for the need for the S130 preheat and primary steam generation phases is: the problem that the water with lower temperature is suddenly supplied to the secondary steam generating chamber, the heating to the steam generating temperature needs time, the requirement of the steam generating amount cannot be met, the steam generating time is delayed, moreover, when the steam is not completely generated, the problem that water is mixed in the steam exists, and the water with lower temperature in the steam generating chamber is preheated before being supplied is solved. In addition, the preheating and the generation of the primary steam and the secondary steam are performed in the same plane space, the structure is simpler without delay, and the preheating and the primary steam generation chamber and the secondary steam generation chamber can be separated by lattice type gap walls (40 of fig. 6), thereby accelerating the generation of the steam.
In addition, the stage S140 is a stage of checking whether the temperature of the steam generating chamber is in accordance with the steam generating temperature, the steam generating temperature is measured by a thermistor, a bimetallic strip or a program is used for controlling the switching action of a power supply, and the temperature is controlled to be about 200 ℃. If the temperature is not proper in the step S140, the temperature control process is completed in the temperature rising and falling process through the temperature control step S150, and the water supply of the secondary steam generating chamber (G of FIG. 6) of the present invention is changed to steam in the step S160.
The power supply of the heating element of the preheating and steam generating part can utilize watt density (density of heating substance) to instantly generate high temperature, when the required temperature is reached (190-200 ℃), the power supply is automatically cut off in the PCB, and when the temperature of the heating element is lower than (140-150 ℃), the power supply is automatically switched on to carry out temperature compensation. When water is supplied (steam generation), the PCB is always adjusted to be connected with the power supply when water is put in (steam generation) aiming at the rapid temperature drop. For this correct temperature control, calculations are made in the IC memory in the PCB, enabling pumping and temperature control. The length of the water channel is proportional to the steam ejection start time. The water channel is long and the steam starts to be ejected later, but the quality of the steam becomes better. The water channel is short and the steam ejection start time is fast, but the quality of the steam may be deteriorated. Therefore, in the present invention, the length of the water passage is shortened, and the heating element is embedded in parallel with the water passage to concentrate the temperature on the water passage. As will be further described in detail below, the volume of the steam path is slowly increased in the direction of steam travel, increasing the volume of steam and the speed of the steam. In addition, as will be described in detail later, a structure for circulating steam is arranged in the middle of the labyrinth-shaped channel, so that the steam flows back, the uniform high temperature of the steam is realized, the high-quality steam can be discharged within the time required by an operator, the operator does not feel inconvenient in the using process, and the purpose of generating and spraying a large amount of stable steam is achieved.

Fig. 6 is a perspective view showing the preheating and steam generating part 4 installed at the upper and rear parts of the soleplate of the electric steam iron of the present invention to preheat the supplied water and generate steam. FIG. 7a is a perspective view showing a heating plate in which the preheating and steam generating part of FIG. 6 is integrally combined and a heating element is fixed. Fig. 7b is a perspective view showing a labyrinth type steam passage formed at a lower portion of the preheating and steam generating part of fig. 6. Fig. 8 is a perspective view showing a labyrinth-type steam passage formed after the preheating and steam generating part of fig. 6 is combined.
Referring to fig. 5 to 8, the present invention includes a preheating and steam generating part (4 of fig. 13) of the electric steam iron, a preheating and primary steam generating chamber F and a secondary steam generating chamber G separated by lattice-type slit walls 40 of fig. 6. The heating element 70 is embedded or fixed on the heating plate integrated with the lower part of the preheating and steam generating part 4, and the power source contact part one 72 and the power source contact part two 74 of the power source cable are shown in the two ends. Both ends (power source contact part one 72, power source contact part two 74) of the heating body 70 of the heating panel are supplied with power through power source cables, and the preheating and steam generating part 4 integrally formed at the upper part of the heating panel is heated to a high temperature. At this time, the supply water at the water inlet E of the preheating and steam generating unit 4 is preheated and primarily vaporized while the preheating and primary steam generating chamber F is flowing. The preheated water and the primarily vaporized steam in the preheating and primary steam generating chamber F pass through the slits formed by the lattice-type slit walls 40, thereby accelerating the vaporization process. Thus, the preheated water and the primary steam passing through the lattice-type gap walls 40 are secondarily vaporized in the aforementioned secondary steam generating chamber G, and more stable and abundant steam is generated. The steam thus generated passes through the steam discharge holes D and then through the steam inlet J of the cover portion of the soleplate 1, and is supplied to the steam passage portion (3 of fig. 13). At this time, the steam discharge hole D is higher than the bottom surface of the periphery, so that the water drops liquefied by the steam do not flow into the steam discharge hole D, thereby discharging the steamThe preheating and steam generating part 4 corresponding to the holes D has a large recess D on its upper surface1. In fig. 6, as shown by an arrow C, the flow time of the supplied water at the water inlet E is designed to be longer in the preheating and primary steam generating chamber F than in the secondary steam generating chamber G, and the lattice-type gap walls 40 between the preheating and primary steam generating chamber F and the secondary steam generating chamber G are designed to retain the water, while the primary steam travels to the secondary steam generating chamber G through the gaps.
As shown in fig. 7b, the lower portion of the heating plate in which the heating element 70 of fig. 7a is embedded or fixed forms a steam passage corresponding to the labyrinth-type steam passage formed by the steam passage portion (3 of fig. 13) of fig. 8. The steam channels of fig. 7b and 8 are combined relatively to form a steam channel I. The steam channel forms a steam inlet J through the steam discharge hole D of the secondary steam generating chamber G, after the generated steam enters, the steam flows along the arrow direction of figures 7b and 8, at least one inclined steam guide part H is arranged on the steam channel I, the width of the steam channel is narrowed, the advancing direction of the steam is guided to the inclined direction, the steam backflow is caused, the steam stored in the steam storage part K on the steam channel I advances, and the steam channel is wider as the steam channel is at the tail end, and the effect of multiplying the pressure of the steam is achieved. This causes the steam to flow back and the steam to flow back, and the steam is supplied to the upper cover (2 of fig. 13) of the soleplate 1 through the steam outlet L and discharged through the steam discharge hole 401 of fig. 4.
The soleplate 1, the steam pathway part 3, the preheating and steam generating part 4 and the cover plate 5, which are the components of the electric steam iron of the present invention, are not described in detail in the present invention, and some or all of them may be constructed to embed or fix heater wires, functioning as a heating plate, in which case the structure in which each heater wire is embedded and fixed may be formed by a casting process or a die-casting process.
The anti-scalding plate 18 is formed in the steam iron of the present invention to prevent a hot part from being touched by a hand holding the handle 10 during an ironing operation. Although not shown in the drawings, a power switch is provided outside the power control unit to perform an ironing operation while discharging steam, and a steam discharge button switch 14 is provided near the handle 10, so that a practitioner who supplies power will understand it, and a detailed description thereof will be omitted.

In addition, the invention has the preheating and steam generating part which completes the preheating and steam generation in the same plane, and generates more stable steam, when the generated steam advances along the labyrinth type steam channel part, the advancing direction of the steam is guided to the inclined direction through the inclined steam guiding part arranged on the bottom surface of the steam channel part, so that the steam flows back, and the purposes of increasing the steam temperature, accelerating the steam speed and multiplying the steam pressure are achieved.
In addition, the preheating and steam generation are completed on the same plane, and the appropriate amount of water supplied to the preheating and steam generation part is maintained, so that the purpose of generating sufficient steam and stable and efficient steam is achieved under the condition of controlling the water supply amount and/or temperature.
In addition, the boiler needs to be started even if the steam is not needed when the conventional boiler mode generates the steam, so that the energy consumption is increased, and the phenomenon that the steam and water drops are discharged together when the conventional water tank mode generates the steam is avoided.
Furthermore, the invention can measure the temperature in the steam generating chamber, keep the temperature which is most easy to generate steam, save electric energy by controlling the power switch, control the water pump motor to control the water quantity supplied to the steam generating chamber, control the steam generated by the steam generating chamber, and realize the minimization of the generating quantity of the steam.
In addition, the water supply from the external water tank or water source needs to be preheated before supplying water to the steam generating chamber, and the time required for vaporization is different due to the water temperature difference.
