Description

Technical Field

[0001] The present invention relates to an electric iron, in particular to an electric iron with a steam collecting chamber. Background Art

[0002] The electric irons in the prior art all have the phenomenon of dripping. The main reason for dripping is that the water vapor in the electric iron is mixed together. During the ironing process, water will be sprayed out together with the steam. The dripping phenomenon seriously affects the ironing effect. In order to solve the dripping problem, many solutions have appeared in the prior art. For example, the utility model patent No. 200820121507.2 in China, published on April 15, 2009, discloses an electric iron, including a body, a handle on the body, a water tank and an electromagnetic pump in the body, an electric heating plate at the bottom of the body, a preheating chamber with a first heating device on the electric heating plate, one end of the preheating chamber is connected to the electromagnetic pump through a water pipe, and the other end of the preheating chamber is connected to a vaporization chamber with a second heating device. The circuit of the second heating device is connected in parallel with the circuit of the first heating device, and the electromagnetic pump switch controls the circuit connection. This solution can make the water vapor sent out of the preheating chamber vaporized again, thereby better improving the vaporization effect of water and reducing water leakage. The above solution improves the vaporization effect by heating twice to reduce water leakage. However, this solution still fails to solve the dripping problem, and using two heating steps not only increases energy consumption, but also results in too high a temperature, which affects ironing. Summary of the invention

[0005] The electric iron with a steam collecting chamber provided by the present invention also has the following subsidiary technical features:

[0006] Further, the steam-water separation device includes a filter core located in the hollow body.

The following description is essentially only exemplary and is not intended to limit the application or use of the present disclosure. It should be understood that in all the drawings, corresponding reference numerals represent the same or corresponding parts and features.

[0028] like Figures 1 to 12 As shown, the present invention provides an electric iron with a steam collecting chamber, comprising a shell 1 and a bottom plate 2 connected to the shell 1, the shell 1 is provided with a handle 11, the bottom plate 2 is provided with a vaporization chamber 25, the bottom plate 2 is also provided with a steam collecting chamber 4, the steam collecting chamber 4 is communicated with the vaporization chamber 25, the bottom of the steam collecting chamber 4 is provided with a steam outlet 41, and the steam outlet 41 is provided with a steam-water separation device 5. The improvement of the present invention lies in the bottom plate structure, and the other structures are mature existing technologies and will not be repeated here. The present invention is provided with a steam collecting chamber 4 and a steam-water separation device 5, which can filter the water in the steam to separate the steam and water and prevent dripping. The present invention forms an internal steam collecting chamber to achieve the purpose of storing the water vapor mixture. The high temperature of the inner and outer walls of the steam collecting chamber can make the temporarily stored water vapor mixture evaporate for a second time, and can also allow liquid water to remain on the inner inclined wall of the gas storage chamber to separate the water vapor mixture again. Finally, the steam (containing a small amount of liquid water) passes through the high-temperature and dense steam-water separation device 5 to obtain dry steam, and the remaining impurities therein are filtered, thereby solving the dripping phenomenon during use.

[0029] See also Figure 5 or Figure 7 In the above embodiment given by the present invention, the peripheral wall of the steam collecting chamber 4 is further connected with a heating body 42. At the same time, the present invention connects the peripheral wall of the steam collecting chamber 4 with a heating body 42, so that the steam collecting chamber 4 maintains a high temperature, thereby being able to perform secondary evaporation on the water vapor mixture in the steam collecting chamber 4 and reduce the content of liquid water.

[0030] See also Figure 5 , Figure 7 and Fig.12 , the above-mentioned embodiment given by the present invention further includes that the steam-water separation device 5 is a columnar body with a gap, and the steam-water separation device 5 is made of a heat-gathering material. The steam-water separation device 5 includes a cylindrical hollow body 51 and a filter core 52 located in the hollow body 51, and the hollow body 51 is inserted into the steam outlet 41. The filter core 52 is formed by winding a metal wire. This embodiment is made of a dense copper mesh. The filter core 52 in the present invention can also be made of other metal materials, or other materials that can be heated and gather temperature. It is mainly to enable the filter core 52 to be heated at high temperature, and when steam passes through, the steam will not condense. The filter core 52 has a high temperature, and can also vaporize the filtered steam-water mixture to reduce the liquid water content.

[0031] See also Figure 5 , Figure 7 and Fig.12 In the above embodiment of the present invention, a flange 53 is formed at one end of the hollow body 51, and the flange 53 is against the outer side of the steam outlet 41. A sealing ring 54 is arranged between the flange 53 and the steam outlet 41. The flange 53 plays a limiting role, and the flange 53 and the sealing ring 54 cooperate to play a sealing role. The steam-water separation device 5 in the present invention can be replaced for easy cleaning.

[0032] See also Figure 5 and Figure 6, in the above embodiment given by the present invention, it is further included that the bottom plate 2 includes a heating bottom plate 21 and an ironing bottom plate 22, and a gap is formed between the heating bottom plate 21 and the ironing bottom plate 22, and the heating bottom plate 21 heats the ironing bottom plate 22 by heat radiation. When the common irons on the market are used, the bottom plate temperature is easy to be too high, which is easy to affect the ironing quality and damage the clothes with poor heat resistance. Once the temperature is lowered, dripping will occur. The bottom plate functional part of the present invention is composed of two layers, wherein the upper heating bottom plate 21 mainly functions to evaporate and heat the water vapor mixture through its own high temperature, and the lower ironing bottom plate 22 controls the final air outlet effect through the steam channel and the hole position. Since the bottom plate is designed in layers, there is a certain distance between the heating bottom plate 21 and the ironing bottom plate 22 in contact with the clothes, so the temperature of the ironing bottom plate 22 can be guaranteed to be between 90-120℃, so as to protect the clothes during ironing, and at the same time, it can avoid dripping due to too low temperature, so as to spray high-temperature dry steam. On the other hand, unlike the integrated design of ordinary irons, the layered design of the bottom plate prevents the evaporation and exhaust functions from interfering with each other, thus achieving a better ironing effect. The heating bottom plate 21 and the ironing bottom plate 22 in the present invention are connected together by a connecting structure, and the temperature of the ironing bottom plate 22 can be controlled by adjusting the gap between the two, so that the temperature of the ironing bottom plate 22 is controllable, which is convenient for design. By accurately controlling the temperature of the ironing bottom plate 22, the ironing needs of different clothes can be met. The steam collecting chamber 4 is a convex structure formed by the upward protrusion of part of the structure of the heating bottom plate 21, and the heating body 42 is located at the bottom of the convex structure.
