Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam iron for general household use.

Conventional Structure and Problems Conventionally, in this type of steam iron, a base 2 having a vaporization chamber 1 and a main tank 3 installed above the base 2 are made of metal or metal. They communicated through a drip nozzle 4 made of a ceramic material or the like. This dripping nozzle 4 is connected to the upper surface of the vaporizing chamber 1 and the water tank 3 via a first packing 6 and a second packing 6 made of an elastic material such as rubber.
It is compressed with the bottom surface of the tube to create a watertight seal. water tank 3
The supply of water to the vaporization chamber 1 is controlled by manually operating an opening/closing rod 7 made of a metal member forming a steam control device using a steam control button 8 projecting above the water tank 3. However, with the above configuration, sealing performance is maintained at the contact surface between the dripping nozzle 4 and the opening/closing rod γ, but since both parts are made of hard materials such as gold frosting and ceramic, the contact surface is There were problems such as it was difficult to maintain sealing performance, the two parts had to be brought into contact with great force, and the operating load of the steam control button 8 was heavy. Furthermore, since a backing is required to seal watertightly between the water tank 3 and the vaporization chamber 1, there are problems such as poor assembly efficiency.

Purpose of the Invention The present invention solves these conventional problems, improves the connection between the drip nozzle and the opening/closing rod, improves the operability of the steam control button, and improves assembly efficiency by reducing the number of parts. This product provides an improved steam iron.

Structure of the Invention The steam iron of the present invention includes a base having a vaporization chamber, a water tank installed on the base, the vaporization chamber,
Equipped with a drip nozzle that communicates with the water tank and a drip control device, and by constructing the drip nozzle from a flexible material, the sealing performance between the drip nozzle and the drip control device is improved, and the number of parts is reduced. The reduction also improves ease of assembly.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 4, reference numeral 11 denotes a base having a vaporizing chamber 12 and a steam outlet 13, and a heater 14 is embedded therein. The vaporization chamber 12 is covered with a vaporization chamber lid 15. 16 is a base cover such as a heat insulating plate, 17 is a handle that forms a water tank 18 together with the base cover 16, and a water inlet 19 for the water tank 18 is provided in front of the handle. Reference numeral 20 denotes a drip nozzle that communicates the water tank 18 and the vaporization chamber 12. The portion is compressed by the lower surface of the water tank 18 and the vaporizing chamber lid 15 forming the upper surface of the vaporizing chamber 11 to form a watertight seal. At this time, since the flange portion 21 is provided with a concave groove portion 22, the inner diameter of the dripping nozzle 2o does not change even if it is compressed. Reference numeral 23 denotes an opening/closing rod made of metal or the like that forms part of the dripping control device 24, and the generation of steam is controlled by manually operating a dripping control button 26 projecting above the handle 17.

To explain the operation in the above configuration, when ironing is in progress and steam is generated, when the dripping control button 24 is manually operated, the opening/closing rod 23 moves upward from the contact surface with the dripping nozzle 2o, and the water tank 18 and the vaporization chamber 12 are communicated with each other. Therefore, water in the water tank 18 is supplied to the vaporization chamber 12, and steam is generated. When the dripping control button 26 is manually operated again, the opening/closing rod 23 is pressed against the dripping nozzle 20 made of a flexible material, so that the contact area can be widened, and therefore the water does not flow into the vaporization chamber 12. supply will definitely be interrupted.

By configuring the dripping nozzle 20 from a flexible material in this way, it is possible to fit a wide contact area with the opening/closing rod 23, thereby improving the sealing performance of the contact area and improving the contact between the two parts. Since the pressure is low and sealing performance can be maintained, the dripping control button 26
The load required for manual operation is also small, and operability can be improved.

Furthermore, since the dripping nozzle 20 is made of a flexible material, the water tank 18 and the vaporization chamber 12 can be watertightly sealed and communicated with each other without using a sealing member such as a backing. The number of parts can be reduced, resulting in lower costs and improved assembly efficiency.

Effects of the Invention As is clear from the above embodiments, the steam iron of the present invention has a particularly good sealing property at the fitting part between the drip nozzle and the drip control device because the drip nozzle is made of a flexible material. In addition, it is possible to improve assembly efficiency by reducing the number of parts.
