Description

[Detailed Description of the Invention] The present invention relates to a steam iron, and particularly, during use, water in a tank is efficiently caused to fall into a vaporization chamber to effectively generate steam.

Normally, in a steam iron, water in a tank installed above the base falls through a so-called nozzle part into a vaporization chamber provided on the top surface of the base, and steam generated in the vaporization chamber is ejected from the bottom surface of the base. However, when in use, the iron body suddenly swings back and forth in the horizontal direction, causing the water in the tank or hot water to flow out from the water inlet, wetting clothing, etc., and unnecessarily increasing the amount of water used.

For this reason, a water inlet lid is provided to close the water inlet, and the lid is provided with a small hole that communicates the inside of the tank with the outside air so that the water in the tank can smoothly fall into the vaporization chamber. However, as mentioned above, when the water surface in the tank becomes rippled during use, the small holes are blocked to stop the water from falling, making it impossible to eject a predetermined amount of steam or no steam at all. occured.

The present invention improves the above points and will be explained below based on the drawings. FIG. 1 shows a side view.

1 is a base in which an electric heater (not shown) is embedded; 2 is an iron cover placed and fixed on the top surface of the base; 3 is a heat insulating cover made of heat-resistant synthetic resin fixed on the top surface of the cover; 4 is the heat insulating cover A handle body 5 is a detachable tank installed above the base 1, and in the embodiment, it is placed on the heat insulating cover 3, and when it is placed, the connecting part 6 provided on the bottom wall is connected to the handle body. It fits into the vaporizing chamber 1a provided on the upper surface of the base 1 via the heat insulating cover 3 and the ironing cover 2.

The tank will be explained with reference to FIGS. 2 and 3. 7 is a trapezoidal tank case made of a substantially transparent synthetic resin; 8 is a decorative cover 9 fixed to the upper surface of the tank case; a front wall plate fixed to the front side of the tank case 7 at an angle; water inlet 1
0 and a pair of protruding walls 11, 11 extending in the vertical direction are formed on both sides thereof, and a locking protrusion 12 is integrally molded on one of the protruding walls. Reference numeral 13 denotes a water filler lid having a semicircular cross section, whose one side fits along the other side of the protrusion wall so that it can be opened and closed laterally, and whose other side engages with the locking protrusion 12. A long hole 14 is bored, and the long hole is provided at a position corresponding to the water inlet 10, and an operating piece 15 is provided on the other side. A cylindrical wall 16 is integrally formed with the cylindrical wall 16 and extends laterally. In this case, it is desirable that the elongated hole 14 be located above the front wall surrounded by the cylindrical wall 16. 1
Reference numeral 7 is provided on the rim of the water inlet 10 and is clamped and fixed between the tank case 7 and the water inlet lid 13. A heat-resistant gasket 18 made of silicone rubber or the like with a pleated inner peripheral edge is fixed to the bottom wall of the tank case 7. 19 is an operation shaft for opening and closing the nozzle portion 18 by means of an operation button 20 provided on the upper part of the tank 5; 21 is an operation shaft provided on the upper surface of the base 1 for controlling the vaporization chamber 1;
This is a connecting cylinder made of an elastic material fixed above a.

Next, we will discuss the operation. When the iron body is in use, water in the tank 5 is pumped in predetermined amounts into the vaporization chamber 1a provided on the top surface of the base 1 via the nozzle part 18.
The steam drops and is vaporized, and is ejected from a steam ejection hole (not shown) provided on the bottom surface of the base 1. However, as the iron body moves back and forth, the water W in the tank sways, but since the long hole 14 is provided at the farthest position from the water surface, it does not reach the long hole and hardly flows out to the outside. .

Therefore, if the tank 5 is moved further than necessary, water will flow into the cylindrical wall 16 and the elongated hole 1
4 and forms a water film due to surface tension, which blocks the intake of air into the tank.However, due to the shape of the long hole, the water film that adheres to the long hole 14 sags under its own weight and bursts in a short time. to improve air intake conditions into the tank.

As described above, the present invention is a system in which water in a tank installed above a base is dripped into a vaporization chamber and vaporized to generate steam, and the tank is provided with a water inlet on the front and the water inlet is blocked. A cylindrical wall that extends in the horizontal direction is formed integrally with the water inlet lid, and a front wall surrounded by the cylindrical wall has a narrow diameter in the vertical direction at a position corresponding to the water inlet. Since the tank has a long hole, even if the tank is moved during use and a water film is created to block the long hole, the water film will sag according to the shape of the long hole and burst in a short time. This improves the air intake condition into the tank. Therefore, water efficiently falls into the vaporization chamber and steam is effectively generated. Furthermore, since the long holes are made into small holes, even if the water in the tank reaches the long holes due to the movement of the main body, it will not flow out to the outside more than necessary. Furthermore, since the cylindrical wall of the water filler lid directly closes the water filler port of the tank, the distance between the water filler cap and the water filler port is shortened, and the tank can be made smaller.
