Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to improving the performance of steam irons used in general households.

As shown in the structure of the conventional example and its problems, a gasket 7° is mounted on a base 6 having a heater 1 buried therein, a vaporizing chamber 2, and a steam distribution chamber 4 in which a steam outlet 3 is located, and a base lid 5 fixed thereto. A drip nozzle 9 was provided through the tank 10, and the water supply to the vaporization chamber 2 was adjusted by adjusting the top and bottom of the opening/closing frame 11. The water droplets supplied to the vaporization chamber 2 instantly turn into steam, which is sent directly from a part of the vaporization chamber 2 to the steam distribution chamber 4 as shown by the arrow, and is generally discharged from the steam outlet 3. there were. However, in this configuration, there is a condition that the relationship between the hole diameter of the drip nozzle 9 and the vaporization capacity of the vaporization chamber 2 must be sufficiently controlled, and if a drop exceeding a predetermined amount occurs, it will overflow from the vaporization chamber 2. There was a problem that overflowing water droplets would spill directly from the steam outlet 3 and stain the fibers. In order to solve this problem, it is a prerequisite to improve the vaporization ability, and it is necessary to devise ways to increase the vaporization chamber volume and surface area. However, the temperature of the surface of base 6 is 3 ・-
In order to correctly detect the temperature, it is common for a thermostat to be installed in the center of the chamber while maintaining an insulating distance from the outer wall of the vaporization chamber, and it has not been possible to easily increase the size of the vaporization chamber 2. Therefore, measures have been proposed to increase the surface area by providing labyrinths and weirs within the vaporization chamber.

However, even if this measure is expected to be effective in terms of vaporization capacity, after many years of use, hard substances contained in the water will remain when it vaporizes, and conversely accumulate in narrow labyrinths and weirs. This had the disadvantage that it would close and the steam iron would lose its functionality.

In order to solve the above-mentioned drawbacks, in recent years there has been a proposal to forcibly send a certain amount of water into the vaporization chamber 2 using a pump device and use the explosive force of instantaneous vaporization to cause the residue to flow out from the steam outlet 3, but this is a labyrinth after all. The disadvantages of the weir were unavoidable.

It is also known that this instantaneously vaporized explosive steam jet power is effective in smoothing out stubborn wrinkles during ironing.

The root cause of this explosive vaporization is that the position of the drip nozzle for normal steam generation in the vaporization chamber and the position where steam is forcibly fed by the pump are separated by a wall, and the temperature in the vaporization chamber where the latter is located is This is due to the prevention of descent and the increased surface area for vaporization when passing through narrow mazes.

Purpose of the Invention The present invention solves the problem that labyrinths and weirs, which are adopted as means for improving vaporization capacity, on the one hand, are the basis for residual accumulation of hard substances such as lime, and achieves the increase in volume that has been desired in recent years. The present invention provides a steam iron having a means for improving vaporizing ability that allows steam to be generated and a structure that prevents the accumulation of residual hard substances.

Structure of the Invention The pace structure of the iron of the present invention eliminates all labyrinths and weirs from the vaporization chamber, but rather provides a flat partition plate along the heater with the highest thermal efficiency and in the steam distribution chamber. Due to the structure of the plate, water droplets spilled from the vaporization chamber are not directly discharged from the 5 l-disteam ejection hole, but are completely vaporized while passing through the upper passage.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 2 to 6, 12 is the steam distribution chamber 4
The upper passage 15 and the lower passage 1 are separated by a partition plate provided in pressure contact with the heater wall 13 and the pace outer circumferential wall 14.
6 and are connected through an opening 17 provided at the front.

In this case, the embodiment has a configuration with one partition plate 12, but if multiple partition plates 12 are provided, the opening from the uppermost layer passage 15 to the next layer is not limited to the front part but the rear part. There may be an opening. However, it is preferable to connect the opening to the bottom layer at the front, because the length of the steam discharged from the steam nozzle 3 is longer at the front and shorter at the rear, which is more suitable for steam ironing. Because there is.

18 is a steam button that moves the opening/closing rod 11 up and down;
When steam is required, it is set in the position pushed upward by the action of the spring 19-page.

Reference numeral 20 denotes an increase steam button, which sucks up water from a water pumping tube 23 by vertically operating a pump device 22 having a check valve 21, passes through a water supply pipe 24, penetrates the tank bottom and pace lid, and enters the vaporization chamber 2. is led to the water supply pipe opening 26 of. Note that the penetrating portion is sealed with a backing 26. To explain the operation in the above configuration, when performing normal steam ironing, when the steam button 18 is positioned upward, the dripping nozzle 9 opens and the water in the tank 10 is supplied to the vaporizing chamber 2, and the water is instantly converted into steam. Thus, water droplets are guided from the partial passage 26 of the vaporization chamber 2 to the upper passage 15, and even if water droplets overflow from the vaporization chamber 2, they can be vaporized within the walls of this passage. Also, when ironing, especially if you want to smooth out stubborn wrinkles in certain areas, you need to apply a lot of water.

At this time, by operating the increasing steam button 2o, a certain amount of water is supplied to the vaporization chamber 2 by the pump action, and similarly, strong steam is generated from the vaporization chamber 2 through the upper passage 16 and from the steam outlet in the lower passage. “It is possible to obtain /-shi.

Effects of the Invention As is clear from the above embodiments, the present invention is particularly characterized by providing a partition plate in the steam distribution chamber and making effective use of the steam distribution chamber. In fact, it is possible to add new functions such as instantaneous increase in steam when used in conjunction with a pump device depending on the ironing process, and it also prevents the steam passage from clogging. It is also effective as a countermeasure.
