The embodiment of the invention provides an electric heating film for heating and being used for an electric iron, and the electric iron comprises a bottom plate 100 for flattening fabrics, wherein the front end of the bottom plate 100 is of a pointed structure, the bottom plate 100 is provided with a lower plate surface 101 which is arranged downwards, the lower plate surface 101 is divided into a front side area positioned at the front side or a rear side area positioned at the rear side, the width of the bottom plate 100 in the left-right direction is gradually reduced along the front-to-rear direction, and the electric heating film is connected with the lower plate surface 101.
Referring to fig. 1 and 2, in an embodiment of the invention, the electrothermal film includes a series film set 210 for heating, a parallel film set 220 for heating, and an electric wire film set 230 electrically connected to the series film set 210 and electrically connected to the parallel film set 220;
The series film group 210 is located in the front side region, and includes a plurality of connection conductive films 212 and a plurality of series resistance films 211 arranged in series and arranged at intervals from left to right for generating heat, one connection conductive film 212 for connecting a pair of adjacent series resistance films 211;
the parallel film group 220 is located in the rear side area and comprises a plurality of parallel resistor films 221 which are arranged in parallel and used for heating, each series resistor film 211 is arranged in a strip shape and extends to the left and right sides, and each parallel resistor film 221 is arranged at intervals along the front-to-back direction;
The wire film group 230 is located in the rear side area and includes a positive wire film 231 and a negative wire film 231, which are all arranged in a strip shape and extend from front to back, the series film group 210 is electrically connected to the positive wire film 231 and the negative wire film 231, one end of any series resistor film 211 is electrically connected to the positive wire film 231, and the other end is electrically connected to the negative wire film 231.
After the electrothermal film is energized, each of the series resistance films 211 and each of the parallel resistance films 221 individually generates heat, and any one of the series resistance films 211 or any one of the parallel resistance films 221 is a heat source, wherein, since the series film group 210 is located in the front region of the lower plate surface 101, the series film group 210 comprises a plurality of series resistance films 211 which are arranged in series and are arranged at intervals from left to right and are used for generating heat, the parallel film group 220 is located in the rear region of the lower plate surface 101, and the parallel film group 220 comprises a plurality of parallel resistance films 221 which are arranged in parallel and extend from left to right and are used for generating heat, thus, each region of the lower plate surface 101 is distributed with a heat source or is adjacent to a heat source, and the heat generated by each of the series resistance films 211 and each of the parallel resistance films 221 is relatively uniformly distributed on the lower plate surface 101, rather than being concentrated in the middle position of the lower plate surface 101, thereby reducing the temperature difference between each region of the lower plate surface 101.
In the above, since each of the series resistance films 211 and each of the parallel resistance films 221 is required to generate heat, it is known from joule's law that each of the series resistance films 211 and each of the parallel resistance films 221 is required to have a certain resistance value.
Further, each of the series resistance films 211 and each of the parallel resistance films 221 are transparent semiconductor resistance films, specifically, each of the series resistance films 211 and each of the parallel resistance films 221 is a tin dioxide (SnO 2) film, each of the series resistance films 211 and each of the parallel resistance films 221 is arranged transparent, which is beneficial to avoiding each of the series resistance films 211 and each of the parallel resistance films 221 from shielding the base plate 100, wherein, in a specific production process, each of the series resistance films 211 and each of the parallel resistance films 221 can be manufactured by adopting a thin film process such as chemical vapor deposition, spray pyrolysis, evaporation after ion sputtering, and the like.
Among the above, the positive electrode wire film 231 and the negative electrode wire film 231 are used only for conduction, the positive electrode wire film 231 and the negative electrode wire film 231 do not need to generate heat, and the lower the resistance value of the positive electrode wire film 231 and the negative electrode wire film 231 is, specifically, the positive electrode wire film 231 and the negative electrode wire film 231 are conductive silver paste, wherein the silver material has high conductivity, and the positive electrode wire film 231 and the negative electrode wire film 231 can be effectively prevented from generating heat. In addition, the silver material has a lower melting point and can be manufactured by adopting thin film processes such as chemical vapor deposition, spray pyrolysis, ion sputtering and evaporation.
Referring to fig. 1 and 2, in the embodiment of the present invention, each series resistor film 211 is disposed in a strip shape, each series resistor film 211 extends in a front-rear direction, and each series resistor film 211 is disposed at intervals along a left-right direction. Based on this structural design, firstly, since the series resistor films 211 are all arranged in a strip shape, each series resistor film 211 extends in the front-rear direction, so that each series resistor film 211 occupies the front side area as much as possible, secondly, each series resistor film 211 is arranged at intervals along the left-right direction, so that heat is prevented from being concentrated only in the middle position of the front side area, and therefore, heat sources are distributed in or adjacent to each area of the front side area, and heat generated by each series resistor film 211 is uniformly distributed in the front side area.
Further, each of the series resistance films 211 extends to the edges of the front and rear sides of the front side region. Since the front region is substantially triangular, the area of the middle position of the front region is larger, and more heat is required, and based on this, the series resistors located at the middle position can generate more heat, so that the heat generated by each series resistor film 211 will be better distributed in the front region.
Further, the series resistance films 211 are arranged at equal intervals in the left-to-right direction. In this way, the heat generated by each series resistive film 211 will be distributed uniformly over the front region.
Referring to fig. 1 and 2, in the embodiment of the present invention, each series resistor film 211 is connected first, and the connection conductive film 212 is disposed in a circular arc shape. Based on this structural design, since each series resistive film 211 is connected first, the length of the connecting conductive film 212 can be reduced, and the connecting conductive film 212 is prevented from being bent around in the front side region, which is advantageous for simplifying the structure of the series film group 210. In addition, since the length of the connection conductive film 212 is short, that is, the connection conductive film 212 has a resistance, normal use of the series resistance film 211 is not affected, and therefore, the connection conductive film 212 may be made of the same material as the series resistance film 211, and thus, the connection conductive film 212 and the series resistance film 211 may be formed together in the manufacturing process, and the connection conductive film 212 and the series resistance film 211 may not be formed separately, which is advantageous in improving production efficiency.
Referring to fig. 1 and 2, in the embodiment of the present invention, the parallel resistive films 221 are disposed at equal intervals in the front-to-back direction. In this way, the heat generated by each parallel resistive film 221 will be distributed uniformly in the rear region.
Referring to fig. 1 and 2, in the embodiment of the present invention, each of the parallel resistive films 221 extends to the edges of the left and right sides of the rear side region. In this way, the parallel resistive films 221 can occupy the rear area as much as possible, and heat is prevented from being concentrated only in the middle of the rear area, and thus the heat generated by the parallel resistive films 221 is uniformly distributed in the rear area due to the fact that the heat generating sources are distributed in or near each area of the rear area.
Referring to fig. 1 and 2, in the embodiment of the present invention, the resistance value of each parallel resistive film 221 is gradually decreased from front to back, that is, the width end of each parallel resistive film 221 in the front-back direction is gradually decreased from front to back.
Referring to fig. 1 and 2, in the embodiment of the present invention, each series resistive film 211 has at least one inflection point on a path disposed from left to back.
In the embodiment of the present invention, the thickness of each series resistance film 211 and the thickness of each parallel resistance film 221 are the same. Thus, each series resistor film 211 and each parallel resistor film 221 can be formed together in the production process, and the two films do not need to be separated, thereby being beneficial to improving the production efficiency. Specifically, each of the series resistive films 211 and each of the parallel resistive films 221 are formed together in a process of manufacturing by a thin film process such as chemical vapor deposition, spray pyrolysis, ion sputtering, and evaporation. Specifically, the thickness of each series resistance film 211 and the thickness of each parallel resistance film 221 are each 0.5mm.
Referring to fig. 1 and 2, in the embodiment of the present invention, the positive electrode wire film 231 and the negative electrode wire film 231 are respectively disposed at the left and right edges of the lower side plate 101 in an extending manner, and one end of each parallel resistor film 221 is electrically connected to the positive electrode wire film 231, and the other end is electrically connected to the negative electrode wire film 231. In this way, with the above configuration, each parallel resistance film 221 can be located between the positive electrode wire film 231 and the negative electrode wire film 231, and when a current passes through each parallel resistance film 221, the current can pass through the entire parallel resistance film 221 instead of a part of the parallel resistance film 221.
Referring to fig. 1 and 2, in the embodiment of the present invention, the ratio of the length of the series membrane group 210 in the front-rear direction to the length of the parallel membrane group 220 in the front-rear direction is 1.2-2, that is, the ratio of the areas of the front side region and the rear side region is 1.2-2.
The invention also provides an electric iron, which comprises a soleplate 100 for flattening fabrics and an electric heating film, wherein the soleplate 100 is provided with a tip at the front end, the soleplate 100 is provided with a lower side plate surface 101 which is arranged downwards, the width of the soleplate 100 in the left-right direction is gradually reduced along the front-to-back direction, the specific structure of the electric heating film refers to the embodiment, and the electric iron adopts all the technical schemes of all the embodiments, so that all the beneficial effects brought by the technical schemes of the embodiment are also provided, and are not repeated.
Further, the base plate 100 is a base plate 100 made of ceramic glass or crystallized glass. Specifically, when in use, the electrothermal film directly generates heat, one part of the heat directly acts on the fabric, and the other part acts on the bottom plate 100, wherein the bottom plate 100 is the bottom plate 100 made of ceramic glass or crystallized glass, and far infrared waves can be generated when the ceramic glass or crystallized glass is preheated, so that the electric iron can iron the fabric and disinfect the fabric.
Further, the electric iron further includes a protective film made of a transparent insulating material covering the heating film on the soleplate 100. Therefore, the heating film can be protected by the arrangement of the protective film, and the heating film is prevented from being rubbed off in ironing.
