Description
- The present invention relates to an electric iron with the steam provided from the boiler.
- The traditional steam iron is provided with a steam pipe to connect the steam boiler. The steam pipe is connected to the steam inlet of the cut-off valve disposed inside the housing of the iron, and the steam outlet is connected to the cavity between the housing and the heating pan. The bottom of the heating pan is disposed with exhaust hole to exhaust the steam in the cavity out. The valve rod of the cut-off valve is connected to the control button, which is extending from the outside to the housing of the iron. When the control button is pressed, the steam inlet of the cut-off valve is connected to the steam outlet, and the steam from the steam pipe is heated by the heating pan when entering into the cavity. Then the steam is exhausted out from the steam holes of the heating pan. When the control button is released, the steam inlet of the cut-off valve is no longer connected to the steam outlet. So the steam from the steam pipe is cut off by the cut-off valve, it won't enter into the cavity or exhaust out from the steam holes. But there are disadvantages: the steam exhausting type is single, which can't take into count both wetting the cloth with high pressure concentration steam and ironing the cloth with large area homogeneous steam.
- The object of the present invention is to provide a steam iron, which solves the problem to take into count both wetting the cloth with high pressure concentration steam and ironing the cloth with large area homogeneous steam.
- The technical proposal of the present invention is:
- A steam iron is provided, the steam pipe is connected between the steam boiler and the steam inlet of the three-way valve, which is disposed inside the housing of the iron; the space between the baffle and the heating pan inside the iron housing is divided into a high pressure steam room and a homogeneous steam room; the first steam outlet of the three-way valve is connected to the high pressure steam room, and the second steam outlet is connected to the homogeneous steam room; at least a small hole is disposed on the heating pan at the bottom of the high pressure steam room, several big holes are disposed on the heating pan at the bottom of the homogeneous steam room; The valve rod of the three-way valve is connected to the control button, which is extending from the outside into the housing; when the valve rod and the control button are situated in the first position, the steam inlet of the three-way valve is connected to the first steam outlet only; when in the second position, the steam inlet of the three-way valve is connected to the second steam outlet only. The steam from the steam pipe is heated by the heating pan when entered into the homogenous steam room and exhausted out through the big holes on the heating pan to iron the cloth.
- Furthermore: when the valve rod and the control button are situated in the third position, the steam inlet of the three-way valve is connected to the two steam inlet at the same time. The steam from the steam pipe is entered into the high pressure steam room and the homogeneous steam room at the same time and heated by the heating pan. When the steam is exhausted out from the small holes on the heating pan to wet the cloth, the steam is also exhausted out through the big holes on the heating pan to iron the cloth.
- In another embodiment: the three-way valve is a slide valve, the steam inlet of the three-way valve is situated in the central section of the valve body, the first steam outlet is situated above the steam inlet, and the second steam outlet is situated below the steam inlet; the portion the valve rod extended into the valve is disposed with two pistons, the distance between the two pistons is slightly larger than the distance between the first steam outlet and the second steam outlet.
- In another embodiment: the three way valve is angle valve, the wall of the valve body is disposed with a first steam outlet, a steam inlet and a second steam outlet in order; the portion the valve rod extended into the valve body is connected to the rotary piston of triangle.
- In another preferred embodiment: the high pressure steam room is bean sprout shaped, the curved portion in the front portion of the U shaped heating pipe of the heating pan is covered by the bean shaped portion, the front portion of the first side straightsection of the U-shaped heating pipe of the heating pan is covered with the stem portion; the homogeneous steam roomis situated in the posteromedial portion of the heating pan, covering the rear portion of the first side straightsection of the U shaped heating pipe and the second side straightseciton. The steam from the steam pipe is full heated by the curved portion in the front portion of the U shaped heating pipe and the front portion of the first side straightsection of the U-shaped heating pipe when entered into the high pressure steam room. So the temperature of the steam is raised fast. The steam from the steam pipe is heated by the rear portion of the first side straightsection of the U shaped heating pipe and the second side straightseciton when entered into the homogeneous steam room. As the larger covering area of the homogeneous steam room, the temperature of the steam exhausted from the homogeneous steam room is lower than that of the high pressure steam room.
- Furthermore: the high temperature steam room and the homogeneous steam room are separately divided into several disjunctive cavities which are connected one after another by the remaining wall, the steam inlet of the high pressure steam room and the homogeneous steam room are separately disposed in the innermost of the disjunctive cavities, the small holes1 of the high pressure steam room and the big holes of the homogeneous steam room are separately disposed on the outermost of the outlet of the disjunctive cavities. As the disjunctive cavities disposed in the high pressure steam room and the homogeneous steam room, the distance the steam passing through the steam pipe is lengthened so with the heating period. So the steam is full heated. Specially: the small holes are situated in the front portion of the high pressure steam room; the big holes are separately situated in the right and the left sides of the homogeneous steam room. With the small holes disposed, the high pressure steam is propitious to be centralized. With the big holes disposed, the homogeneous steam is propitious to be exhausted homogeneously.
- The present invention of a steam iron is disposed with a high pressure steam room and a homogeneous steam room on the heating pan. The three way valve is applied to choose the steam from the high pressure steam room or the homogeneous steam room through the steam pipe to be heated secondary on the heating pan, then the steam will be exhausted from the corresponding holes. The high pressure steam is centralized in a central region on the heating pan to wet the cloth faster and more effective. The large scale of homogeneous steam is exhausted in another region on the hating pan to iron the large scale of cloth. The steam is exhausted in the two regions, which can iron with large steam. The free change of the three iron states is achieved, which satisfies the customers' different needs. In the preferred embodiment, the steam from the boiler is passed through the steam pipe and exhausted out from the front of the heating pan with high temperature and centralized. The high temperature makes the iron without wrinkle faster; the centralization makes the steam passing through thick cloth easier. The steam from the boiler is passed through the rear portion of the heating pan and exhausted out from the right side and the left side of the heating pan as dry steam, which can iron the cloth with large scale. The present invention of a steam iron is provided more convenient for the users.
