Description
Technical Field
[0001] The utility model belongs to the technical field of electric irons, and in particular relates to a double-sided vaporization cavity structure of an electric iron. Background Art
[0002] As a household appliance, electric irons have become an important tool for ironing clothes since their introduction. With the advancement of technology and the improvement of quality of life, the design and function of electric irons are also constantly evolving, especially the structure of the electric iron soleplate, which directly affects the ironing efficiency and clothing care effect. The traditional electric iron soleplate structure is mainly divided into two types: single cavity and multi-hole steam spray, but these designs have certain limitations and disadvantages.
[0003] The soleplate of a single-chamber electric iron usually consists of a heating element and a steam chamber. The heating element directly heats the water in the chamber, and the steam is ejected through several small holes on the soleplate after being generated. This structure is simple and low-cost, but some problems are exposed in actual use: Uneven steam: Since steam generation and injection are completed in the same area, the distribution of steam is often not uniform, resulting in poor ironing effect on certain parts of clothing. High energy consumption: It is difficult for the single-chamber structure to effectively utilize thermal energy, and the steam generation efficiency is low, consuming more electricity. High steam humidity: Steam is ejected immediately after it is generated and is not fully dried. Overly wet steam can easily cause water stains on clothing, affecting the appearance. Inconvenient maintenance: Once water or scale accumulates inside the single-chamber structure, it is difficult to clean and maintain. Utility Model Content

[0017] The bottom plate is provided with a heating element and holes corresponding to the steam outlet holes. The heating element is located inside the bottom plate and is used for constant temperature treatment of the temperature of the steam outlet from the holes when the bottom plate is connected to the electric iron.
[0018] The power of the water pump matches the heating power of the evaporator to ensure the steam generation efficiency.

[0034] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.
[0035] like Figure 1 , Figure 3 As shown, it is a first embodiment of a double-sided vaporization chamber structure of an electric iron provided by the utility model. In this embodiment, the electric iron is detachably connected to the soleplate. The electric iron comprises an evaporator 10, an upper cover 20 of the vaporization chamber, a bottom cover 21 of the vaporization chamber, and a connecting channel 40. The evaporator 10 and the upper cover 20 of the vaporization chamber constitute a first vaporization chamber 11, and the evaporator and the bottom cover 21 of the vaporization chamber constitute a second vaporization chamber 12. The first vaporization chamber and the second vaporization chamber are located inside the electric iron. The evaporator 10 is provided with a connecting channel 40, and the connecting channel 40 is used to connect the first vaporization chamber 11 and the second vaporization chamber 12. The evaporator 10 and the upper cover 20 of the vaporization chamber are fixedly connected by a card slot and a protrusion, and the evaporator 10 and the bottom cover 21 of the vaporization chamber are fixedly connected by a card slot and a protrusion. The detachable connection includes a snap connection, a threaded connection, etc.
[0036] When the electric iron is turned on, the built-in precision water pump starts working, extracting a fixed amount of water from the water tank and delivering it to the first steaming chamber inside the electric iron. This process ensures the water supply required for steam generation. At the same time, the precise control capability of the water pump also helps to adjust the steam generation rate to meet different ironing needs.
[0037] The water entering the first vaporization chamber is subjected to the high temperature from the bottom heating element, and begins to heat up rapidly and undergo a preliminary vaporization process. Different from the single heating mode of the traditional electric iron, the utility model adopts the rotary heating technology, that is, the heating element not only heats from the bottom, but also promotes the uniform heating of water molecules by rotating or oscillating, thus accelerating the vaporization reaction. At this stage, the water is converted into a water vapor mixture, but the steam at this time still contains a high moisture content and has not reached the optimal dryness.
[0038] The initially formed water vapor mixture is then guided to the second vaporization chamber through the connecting channel. This connecting channel can not only prevent the water vapor mixture from cooling during the transmission process, but also further accelerate its flow, thereby improving the heat exchange efficiency of the overall system. After reaching the second vaporization chamber, the water vapor mixture is subjected to high-intensity heating treatment again. This process not only further promotes the vaporization of water molecules, but more importantly, through the continuous high temperature action, the deep drying of the steam is achieved, the moisture content in the steam is reduced, and high-quality steam with extremely high dryness is obtained. Among them, in the above technical solution, the ironing working surface of the vaporization chamber bottom cover 21 is provided with a plurality of steam outlet holes 211, and the steam outlet holes 211 penetrate the vaporization chamber bottom cover 21.
[0039] Furthermore, in the above technical solution, the vaporization chamber upper cover 20 is provided with a water hole 201 , and the evaporator 10 is provided with a depression at a position corresponding to the water hole 201 .
[0040] like Figure 2 , Figure 5 As shown, further, in the above technical solution, the first vaporization chamber 11 is specifically a spiral structure with the concave position as the starting point and the connecting channel 40 position as the end point. Figure 3 The first vaporization chamber is specifically the area surrounded by the red line. Figure 5 The first vaporization chamber is specifically the area where the red line passes.
[0041] like Figure 4 , Figure 6 As shown, further, in the above technical solution, the second vaporization chamber 12 is an axisymmetric structure corresponding to the connecting channel 40. Figure 5 The second vaporization chamber is specifically the area surrounded by the red line. Figure 6 The second vaporization chamber is specifically the area where the red line passes.
[0042] It should be noted that the water pump draws water from the water tank to the evaporator, and the evaporator cooperates with the protrusions on the vaporization chamber upper cover and the vaporization chamber bottom cover through the grooves on its edges to form a sealed first vaporization chamber and a second vaporization chamber respectively.
[0043] When all parts are assembled, the steam flow path forms a coherent path. Water is pumped from the water pump to the evaporator, initially vaporized in the first vaporization chamber, transported to the second vaporization chamber through the connecting channel, and deeply vaporized and dried in the second vaporization chamber. The entire steam flow path structure ensures the sealing and structural stability of the vaporization chamber through the connection method of the slot and the protrusion, effectively preventing steam leakage, and facilitating maintenance and cleaning.
[0044] Furthermore, in the above technical solution, the volume ratio of the first vaporization chamber 11 to the second vaporization chamber 12 is 1:1.5.
[0045] Furthermore, in the above technical solution, a water pump is also included, which is connected to the first vaporization chamber 11 and is used to transport water into the first vaporization chamber 11 for heating and vaporization.
[0046] The sole plate is provided with a heating element and a hole corresponding to the steam outlet hole. The heating element is located inside the sole plate and is used to treat the temperature of the steam coming out of the hole at a constant temperature when the sole plate is connected to the electric iron. The device includes two steam outlet conditions: first, when the sole plate is not connected, steam is discharged through the steam outlet hole; second, after the sole plate is connected, steam is discharged through the hole corresponding to the steam outlet hole set on the sole plate, wherein the sole plate is also provided with a heating element for treating the temperature of the steam flowing through the sole plate at a constant temperature. After the coupler is plugged in, the heating element can be powered on to heat.
[0047] Specifically, the principle of the utility model is:
[0048] Staged steam generation: The steam generation process is divided into two stages, the first vaporization chamber is responsible for preliminary heating and vaporization, and the second vaporization chamber is used for further heating and drying to achieve high-quality steam generation; the flow of steam begins with the water pump (4) supplying water to the evaporator (1), and the water is heated in the first vaporization chamber (6) and converted into a water vapor mixture. This initially vaporized water vapor mixture then passes through a connecting channel, which is designed to prevent condensation and accelerate the flow of the water vapor mixture, thereby guiding it into the second vaporization chamber; in the second vaporization chamber, the water vapor mixture undergoes secondary heating to achieve deep vaporization and drying, and finally forms high-quality steam, which is output to the working surface of the electric iron through the steam flow channel;
[0049] Efficient heat energy utilization: The dual-chamber structure allows the heat energy to be fully utilized in the two vaporization chambers, reducing energy waste and improving the overall energy efficiency of the iron;
[0050] Steam quality optimization: The drying process of the second vaporization chamber effectively reduces the moisture content in the steam, avoids water stains that may occur during ironing, and improves the ironing effect;
[0051] Structural optimization and connection design: The evaporator is connected to the vaporization chamber upper cover and vaporization chamber bottom cover through slots and protrusions, which not only ensures the stability and sealing of the structure, but also simplifies the assembly process and facilitates subsequent cleaning and maintenance.
