[0022] In order to make the purpose, technical solutions and advantages of the application clearer, the technical solutions in the application will be described clearly and completely below in combination with the drawings in the application. Obviously, the described embodiments are some embodiments of the application, but not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0023] The iron 100 according to the present application is described below in conjunction with Figs. 1-5. It is to be noted that the iron 100 is a common household appliance, and its main function is to remove wrinkles on clothes through heating and pressure, so as to restore the clothes to a flat and smooth state. When using the iron 100, the user can set different heat levels according to the material of the clothes and the required temperature. For example, clothes made of cotton and linen may require a higher temperature to effectively remove wrinkles, while delicate or synthetic fabrics such as silk and polyester require a lower temperature to avoid damage. The iron 100 can also be equipped with a temperature adjustment knob or a digital display screen, so that the user can conveniently select the temperature setting most suitable for their clothes.

[0024] As shown in Figs. 1 and 2, the iron 100 according to the present application comprises a main body portion 110, a steam generator 120, and a working portion 130.

[0025] Specifically, referring to Figs. 2 and 3, the steam generator 120 is arranged in the main body portion 110, and at least one of the working portion 130 and the steam generator 120 defines a steam backfill cavity 121. The working portion 130 has a steam port 142 and an air suction port 152, and the steam port 142 is in communication with the steam backfill cavity 121. As shown by arrow b in Figs. 4 and 7, the steam generated by the steam generator 120 is adapted to be sprayed out through the steam backfill cavity 121 and the steam port 142. The steam backfill cavity 121 can be a closed chamber, and water is converted into steam by the steam generator 120, and the steam is then subjected to secondary heating in the steam backfill cavity 121 to prevent condensate from forming when the steam cools down, thereby reducing the spraying of water from the iron 100 and ensuring the amount of steam sprayed, thereby improving the performance of the iron 100.

[0026] As shown in Fig. 2, the main body portion 110 is provided with an air outlet 111, and the main body portion 110 is provided with an air duct cavity 116, and the air suction port 152 and the air outlet 111 are in communication through the air duct cavity 116, together forming the main air duct of the iron, and the airflow can enter the housing 112 from the air suction port 152 and flow to the air outlet 111 under the guidance of the air duct cavity 116, and then the airflow can flow out of the air outlet 111, as shown by arrow a in Fig. 7. In this way, the iron 100 can have an air suction function, so that it does not need to be equipped with a separate ironing board, i.e. it can achieve good ironing results without the aid of an ironing board, making the iron 100 more portable and convenient for the user to carry.

[0027] According to the iron 100 provided by the embodiment of the present application, the steam backfill cavity 121 is arranged between the working part 130 and the steam generator 120, water is formed into steam spray by the steam generator 120, and the steam is heated again by the steam backfill cavity 121 to prevent the steam from forming condensate water due to cold, thereby reducing the water spray of the iron 100, ensuring the amount of steam spray, and improving the use performance of the iron 100.

[0028] As shown in FIGS. 2 and 3, according to some embodiments of the present application, the main body part 110 can include a shell 112, a water tank 1123, a motor 114, and an electric control assembly.

[0029] Specifically, the shell 112 is provided with an open mouth 1121, the steam generator 120 is arranged in the shell 112 and located at the open mouth 1121, the working part 130 is arranged at the open mouth 1121 to block the open mouth 1121, and the steam backfill cavity 121 is located at the open mouth 1121.

[0030] The shell 112 is provided with the air duct cavity 116, the air outlet 111 is arranged on the shell 112 and communicates with the air duct cavity 116, the first cavity 115 and the second cavity 1125 jointly constitute the air duct cavity, the first cavity 115 communicates with the air inlet 152, the second cavity 1125 communicates with the air outlet 111, the air inlet 152 and the air outlet 111 communicate with each other through the air duct cavity 116 to jointly form the main air duct of the iron. The water tank 1123 is connected with the shell 112. The water tank 1123 communicates with the steam generator 120 through the water pipe 1131, and the water tank 1123 can be used to store water to supply water to the steam generator 120. In order to facilitate the supply of water in the water tank 1123 to the steam generator 120, a water pump 1132 can be arranged in the shell 112, and the water pump 1132 can provide directional power for water flow.

[0031] It should be noted that the water tank 1123 and the shell 112 can be detachably connected or buckled by buckling or other forms to facilitate disassembly of the water tank 1123 and water filling.

[0032] The motor 114 is arranged in the air duct cavity 116 to drive the airflow in the air duct cavity 116 to flow. The electric control assembly is arranged in the shell 112, and the electric control assembly is electrically connected with the motor 114 and the steam generator 120. It should be noted that the electric control assembly can control the normal operation of the motor 114, the steam generator 120, and the water pump 1132. The motor 114 can generate suction when working to drive the airflow to flow, so that the airflow can enter the shell 112 from the air inlet 152.

[0033] The first chamber 115, the second chamber 1125 and the third chamber 1124 are spaced apart from each other in the shell 112. The steam generator 120 is located in the first chamber 115. The air suction surface 151 is located on the side of the air suction member 150 away from the steam generator 120. The air suction surface 151 is provided with an air suction port 152 penetrating through the air suction member 150. The air duct cavity 116 is in communication with the air suction port 152. The air outlet 111 is provided on the top of the shell 112 and is in communication with the second chamber 1125. The water pump 1132 is located in the third chamber 1124.

[0034] The motor 114 is arranged in the first chamber 115. The electric control assembly is arranged in the third chamber 1124. In this way, the water circuit, the electric circuit and the gas circuit can be isolated from each other, so that the safety factor of the ironing machine 100 can be improved.

[0035] The first chamber 115 is provided with an open port 1121. The third chamber 1124 is provided with a heat dissipation port. The steam generator 120 is located close to the open port 1121. The motor 114 is located on the side of the steam generator 120 away from the open port 1121.

[0036] According to some embodiments of the present application, as shown in FIGS. 2 and 4, the working part 130 can include a heat distribution member 140 and an air suction member 150. Specifically, the heat distribution member 140 is connected with the steam generator 120. The steam port 142 penetrates through the heat distribution member 140. The steam generator 120 and the heat distribution member 140 define the steam backfill cavity. The heat distribution member 140 can be the main component for realizing the ironing function. The heat distribution member 140 can uniformly distribute heat. The steam generated by the steam generator 120 can be sprayed to the clothes to be ironed through the steam port 142. The clothes to be ironed can be ironed under the joint action of the heat distribution member 140 and the steam.

[0037] As shown in FIGS. 3 and 4, the air suction member 150 is arranged at the heat distribution member 140. In some examples, the air suction member 150 is connected with the heat distribution member 140. The air suction port 152 penetrates through the air suction member 150. The heat distribution member 140 and the air suction member 150 are located on the same side of the steam generator 120.

[0038] According to some embodiments of the present application, as shown in FIGS. 2 and 4, the heat distribution member 140 is provided with a groove 143. The steam port 142 is arranged in the groove 143. When the ironing machine works, the clothes to be ironed are sucked. A concave steam area is formed between the clothes and the groove 143. The steam gathered in this area can increase the temperature of the surface of the clothes, which is beneficial to improve the ironing effect. The probability of the steam being sucked into the shell is reduced, and the utilization rate of the steam can be improved.

[0039] In order to improve the ironing effect of the ironing machine 100, in some examples, referring to FIG. 4, the surface of the heat equalizing member 140 facing away from the steam generator 120 is in the same plane as the surface of the air suction member 150 facing away from the steam generator 120. In this way, the surfaces of the heat equalizing member 140 and the air suction member 150 facing the clothes to be ironed are in the same plane, and the ironing effect of the heat equalizing member 140 and the air suction member 150 on the clothes is more uniform when the ironing machine 100 is used.

[0040] According to some embodiments of the present application, as shown in FIGS. 3 and 4, the working part 130 can further include a filter plate 160 connected to the heat equalizing member 140, the filter plate 160 being provided with a filter opening 161 penetrating the filter plate 160, and the filter plate 160 and the air suction member 150 being sleeved on the periphery of the heat equalizing member 140. The filter plate 160 and the air suction member 150 are arranged in layers, the filter plate 160 being located on the side of the air suction member 150 facing the steam generator 120, and the filter opening 161 being in communication with the air suction opening 152. In this way, the filter plate 160 can filter the airflow entering the air duct cavity 116 to prevent sundries from entering the housing 112.

[0041] In some embodiments, the filter opening 161 and the air suction opening 152 are both a plurality of openings, the total area of the plurality of filter openings 161 being greater than the total area of the plurality of air suction openings 152. Further, the ratio of the total area of the plurality of filter openings 161 to the total area of the plurality of air suction openings 152 ranges from 1.3 to 1.8. Preferably, the total area of the plurality of filter openings 161 is 1.3 times, 1.5 times, or 1.8 times the total area of the plurality of air suction openings 152, so as to increase the airflow space.

[0042] According to some embodiments of the present application, a filter layer is provided between the filter plate 160 and the air suction member 150. The filter layer can capture and remove tiny particles, dust, and other potential pollutants in the air. The filter layer can be a HEPA element, which is usually composed of multiple layers of fibers that are densely interwoven to form an effective barrier that can intercept most particulate matter. When air is sucked in through the air suction member 150, it can first pass through the filter layer. Since the filter layer can slow down the airflow, it increases the chances of particles coming into contact with the fibers, so that the particles are effectively captured in the filter layer. In summary, the filter layer provided between the filter plate 160 and the air suction member 150 can improve the filtering performance of the entire system through physical interception, protecting the subsequent filter plate 160 and providing a convenient maintenance method for maintenance personnel.

[0043] In order to facilitate installation of the filter layer, as shown in FIGS. 3 and 4, according to some embodiments of the present application, the air suction member 150 is provided with a first buffer groove 153 on a side facing the filter plate 160, the filter layer is arranged in the first buffer groove 153, and the air suction port 152 and the filter port 161 are both in communication with the first buffer groove 153.

[0044] As shown in FIGS. 3 and 4, according to some embodiments of the present application, the filter plate 160 is provided with a second buffer groove 162 on a side facing away from the air suction member 150, an opening of the second buffer groove 162 faces the main body part 110, and the second buffer groove 162 is in communication with the filter port 161 and the air outlet 111. In this way, the airflow can be buffered in the second buffer groove 162, so as to reduce the turbulence effect and reduce the airflow noise.

[0045] In order to further optimize the structural arrangement of the air suction member 150 and the filter plate 160, according to some embodiments of the present application, as shown in FIG. 2, the air suction member 150 and the filter plate 160 are both annular, and the heat equalizing member 140 is embedded in the inner ring of the filter plate 160. In some examples, the heat equalizing member 140 can be a plate structure made of metal material, for example, the heat equalizing member 140 can be a plate structure made of aluminum alloy. The heat equalizing member 140 is in contact with the steam generator 120, so that the temperature of the steam generator 120 is thermally conducted to the heat equalizing member 140, which can heat the clothes and assist the steam ironing, so as to achieve a better ironing effect.

[0046] According to some embodiments of the present application, as shown in FIG. 5, the working part 130 has a working surface 131 adapted to contact the clothes to be ironed. The working surface 131 includes a heat equalizing surface 141 and an air suction surface 151, the heat equalizing surface 141 is provided with a steam port 142 in communication with the steam back-charging cavity 121, and the air suction surface 151 has an air suction port 152 in communication with the air outlet 111. The area of the heat equalizing surface 141 is S1, the area of the air suction surface 151 is S2, and the ratio of S1 / (S1+S2) is in the range of 0.4-0.7. Preferably, S1 / (S1+S2) can be 0.4, 0.45 or 0.7. It should be noted that the larger the area of the heat equalizing surface 141, the larger the contact area with the clothes during ironing, and the temperature of the heat equalizing surface 141 can assist the steam to iron the clothes more flat. After the heating area of the clothes is increased, it is also beneficial to improve the ironing time efficiency.

[0047] According to the ironing machine 100 of the embodiments of the present application, by optimizing the area relationship between the heat equalizing surface 141 and the air suction surface 151, the contact area between the heat equalizing surface 141 and the clothes can be increased, and during ironing, the temperature of the heat equalizing surface 141 can assist the steam to iron the clothes more flat. In addition, after the heating area of the clothes is increased, it is also beneficial to improve the ironing time efficiency.

[0048] According to some embodiments of the present application, as shown in Fig. 5, the suction port 152 is multiple, and the total area of the multiple suction ports 152 is 0.3-0.5 times the area of the surface of the air suction member 150 facing away from the steam generator 120. In other words, the total area of the suction ports 152 can account for 30%-50% of the total area of the air suction member 150. Preferably, the total area of the suction ports 152 can account for 30% or 50% of the total area of the air suction member 150. It can be understood that the suction efficiency of the motor 114 is related to the surface hole area, which is the flow rate of the air passing through. When the flow rate of the air is low, the suction value of the motor 114 will decrease. Therefore, the hole area of the suction port 152 is designed to be larger, so that a greater suction can be obtained, thereby improving the ironing effect and making the ironed clothes more flat.
