Description

Electric iron using boiler steam generator

Technical field

The present invention relates to the structure of an electric iron, and more particularly to an electric iron using a boiler type steam generating device.

Background technique

Electric irons are one of the most commonly used everyday appliances in people's daily lives. In order to ensure that the clothes are not damaged and can be ironed more flatly, the most primitive method is to spray some water on the surface of the clothes. This method is cumbersome to operate and it is difficult to uniformly spray water onto the surface of the clothes. Later, the designer set up a water tank in the electric iron to spray water directly from the ironing board of the iron, which is convenient to operate and evenly sprayed.

With the improvement of people's living standards and the awareness of the quality of the dress, people's requirements for the iron are getting more and more sturdy, so there is a spray iron. For example, Chinese Patent No. CN98102941. No. 8 discloses a "spray steam iron" whose structure includes a water tank for storing water, an evaporation chamber for evaporating water in the water tank to generate steam, and is used to form an evaporation chamber. a base, a heater for heating the base, covering the base cover on the upper side of the base, for introducing water in the water tank into the first passage of the evaporation chamber, the mixing chamber, and the water in the tank in the mixing chamber Forming tiny particles under the action of the vapor flow rate generated in the evaporation chamber for introducing water from the water tank into the second passage of the mixing chamber for introducing steam from the evaporation chamber into the steam passage of the mixing chamber, and for acting on the steam A nozzle that sprays water from the mixing chamber.

The spray mist sprayed by the above steam steam iron is a mixture of liquid water and water vapor, wherein the steam content is small, and the pressure of the spray is insufficient, and the effect is better when the clothes are laid flat on a horizontal surface, but the effect is good. It is not good for hanging ironing. There are other types of steam irons on the market, but they all have the disadvantages of low steam and insufficient pressure.

In the case where a large amount of steam is required in the industry, it is common to use a boiler-type steam station connected to the electric iron to supply steam with sufficient pressure to the electric iron. The principle of generating steam is the same as that of the industrial boiler, because of its volume. Large, it is inconvenient to use, so it is difficult to promote in the field of daily life.

Therefore, the designer designs the boiler steam generating device and the electric passenger bucket as one body. The key is that the volume is small enough, which requires the size of the switching valve to be small enough and to meet the requirements of safety regulations. The solenoid valve meets the safety requirements, but its volume cannot reach the minimum limit.
