Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot water appliances, and in particular to steam generators. Background Technology
[0002] Steam generators play an important role in daily life, and can be used for heating, cooking, and ironing and cleaning clothes.
[0003] Due to size and weight limitations, household steam generators cannot generate enough power to produce sufficient heat for steam. This results in water spraying and dripping during startup. The moisture produced can accumulate inside the generator, forming dirt or clogging, affecting its normal operation. When ironing clothes, the spraying and dripping water can make garments too wet, damaging some water-sensitive fabrics. Furthermore, excessive moisture from the spraying and dripping water increases ironing time, reducing efficiency.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a steam generator to reduce the phenomenon of water spraying and dripping from the steam generator.
[0006] The technical solution of this utility model is as follows:
[0007] A steam generator, the steam generator comprising a heating element, a housing, and a cover plate;
[0008] The heating element is disposed inside the housing;
[0009] The shell has flow channels with the openings facing upwards;
[0010] The cover plate is disposed on the housing to seal the flow channel; the cover plate has a water inlet and a steam outlet, and the water inlet and the steam outlet are respectively connected to the flow channel;
[0011] The flow channel sequence includes a first section, a second section, and a third section; the first section and the second section are folded in half, with the bottom of the second section being higher than the bottom of the first section; the second section and the third section are folded in half, with the bottom of the third section being higher than the bottom of the second section; the water inlet is connected to the first section, and the steam outlet is connected to the third section.
[0012] A further technical solution is that the first segment is located in the middle of the shell; the second segment consists of two independent segments, with the second segment located on the opposite side of the first segment.
[0013] A further technical solution is that the third segment is provided in two parts, with the third segment being connected to the second segment independently; the two parts are connected at the ends of the third segment that are furthest from the second segment.
[0014] A further technical solution is that the steam outlet is located at the connection point between the two sections of the third section.
[0015] A further technical solution is that the heating element includes a heating section and pins; the flow channel is biased to one side of the heating section.
[0016] A further technical solution is that the water inlet is located on the side near the heating section, and the steam outlet is located on the side near the pin.
[0017] A further technical solution is to provide protrusions at the bottom of the first segment and the third segment.
[0018] A further technical solution is that the inner wall of the second segment is smooth.
[0019] A further technical solution is that the outer edges of the shell and the cover plate are fitted together by male and female stops.
[0020] A further technical solution is to install a temperature detection and control element on the housing between the water inlet and the steam outlet.
[0021] The beneficial technical effects of this utility model are as follows:
[0022] (1) The steam generator of this utility model has a flow channel comprising a first section, a second section, and a third section. The first and second sections are folded together, as are the second and third sections. This folding arrangement effectively reduces the space occupied by the flow channel, facilitating the arrangement of a flow channel with sufficient area and length within a limited space, ensuring that the flow channel is close to the heating element. The proximity of the heating element to the flow channel improves heat transfer efficiency. This allows the heating element to fully heat the medium within the flow channel, ensuring the heat of the steam and reducing the occurrence of water spraying and dripping. At the same time, the bottom of the second section is higher than the bottom of the first section, and the bottom of the third section is higher than the bottom of the second section, preventing liquid water from entering the flow channel of the next section, while the steam remains unaffected, achieving water-vapor separation.
[0023] (2) Further, the first section is located in the middle of the shell. The second and third sections consist of two sections symmetrically arranged on opposite sides of the first section. The first section is located in the middle of the shell to ensure that the heating element is fully supplied with the liquid entering the first section. Then the second and third sections are symmetrically arranged around the first section, so that the water vapor entering the different second and third sections is heated to a uniform temperature. This makes the overall temperature of the steam generator more balanced.
[0024] (3) Furthermore, protrusions are provided at the bottom of the first and third sections. The protrusions increase the surface area of the flow channels in the first and third sections, improve the heat exchange efficiency between the flow channels and water vapor, and thus increase the heat of the steam.

[0030] Figure 1 A three-dimensional structural schematic diagram of the steam generator of this utility model is shown. Please refer to it. Figure 1The steam generator includes a heating element 3, a housing 1, and a cover plate 2. The heating element 3 is disposed inside the housing 1, and the heat from the heating element 3 is transferred to the steam through the housing 1. A flow channel 11 is formed on the housing 1, with the opening of the flow channel 11 facing upwards. The cover plate 2 is disposed on the housing 1 and seals the flow channel 11. The cover plate 2 has an inlet 21 and a steam outlet 22, which are respectively connected to the flow channel 11. Liquid enters the flow channel 11 through the inlet 21 and is heated. The steam generated by heating rises and is discharged through the steam outlet 22. The flow channel 11 sequentially includes a first section 111, a second section 112, and a third section 113. The first section 111 and the second section 112 are folded together, with the bottom of the second section 112 higher than the bottom of the first section 111. The second section 112 and the third section 113 are folded together, with the bottom of the third section 113 higher than the bottom of the second section 112. The inlet 21 connects to the first section 111, and the outlet 22 connects to the third section 113. This folded design effectively reduces the space occupied by the flow channel 11, allowing for a sufficient area and length of flow channel 11 within a limited space, ensuring the flow channel 11 is close to the heating element 3. The proximity of the heating element 3 to the flow channel 11 improves heat transfer efficiency. This allows the heating element 3 to fully heat the medium within the flow channel 11, ensuring sufficient heat for the steam and reducing water spraying and dripping. Simultaneously, the bottom of the second section 112 is higher than the bottom of the first section 111, and the bottom of the third section 113 is higher than the bottom of the second section 112, preventing liquid water from entering the next section of the flow channel 11 while leaving the steam unaffected, thus achieving water-vapor separation.
[0031] Please refer to Figure 1 The first segment 111 is located in the middle of the housing 1. The second segment 112 consists of two independent sections, positioned opposite the first segment 111. The first segment 111 is located in the middle of the housing 1 to ensure that the heating element 3 is fully supplied with liquid entering the first segment 111. The second segments 112 are then symmetrically arranged around the first segment 111, ensuring that the water vapor entering the different second segments 112 is heated to a uniform temperature.
[0032] Preferably, the third segment 113 is provided in two parts, with each part connected to the second segment 112. The ends of the two third segments 113 furthest from the second segment 112 are connected. The third segments 113 are symmetrically arranged around the first segment 111, so that the water vapor entering the different third segments 113 is heated evenly. Furthermore, the connection between the two third segments 113 ensures that the heat of the steam entering the different third segments 113 is mixed evenly.
[0033] More preferably, the steam outlet 22 is located at the junction of the two third sections 113. After the steam entering the different third sections 113 is mixed with heat evenly, it is discharged from the steam outlet 22, so that the steam discharged from the steam generator has a uniform temperature.
[0034] Please refer to Figure 1The heating element 3 includes a heating section 32 and pins 31. The flow channel 11 is biased towards one side of the heating section 32. Specifically, the water inlet 21 is closer to the heating section 32, and the steam outlet 22 is closer to the pins 31. The proximity of the heating section 32 to the flow channel 11 improves heat transfer efficiency. This allows the heating element 3 to fully heat the medium within the flow channel 11, ensuring the heat of the steam.
[0035] A temperature detection and control element 4 is installed on the housing 1 between the water inlet 21 and the steam outlet 22. The temperature detection and control element 4 monitors the heating status of the medium in the flow channel 11. This temperature detection and control element 4 can be a commercially available Yudian AI-9 type single-loop regulator.
[0036] Please refer to Figure 1 The bottom of the first section 111 and the third section 113 is provided with a protrusion 114. The protrusion 114 increases the surface area of the flow channel 11 at the first section 111 and the third section 113, improves the heat exchange efficiency between the flow channel 11 and the water vapor, and thus increases the heat of the steam.
[0037] Preferably, the inner wall of the second section 112 is smooth. The medium within the second section 112 has not yet received sufficient heat, resulting in significant scale buildup. The flat inner wall of the second section 112 facilitates water drainage, reducing scale accumulation.
[0038] More preferably, the outer edges of the shell 1 and the cover plate 2 are fitted together by male and female stops 12. The male and female stops 12 facilitate accurate positioning between the shell 1 and the cover plate 2, reduce assembly errors, and improve the stability of the overall structure. This fitting method can also withstand large axial and radial loads, ensuring the structural strength of the steam generator.
[0039] The specific workflow of this utility model is as follows:
[0040] When the steam generator is working, the heating element 3 is powered on, and water is injected into the first section 111 through the water inlet. The water entering the first section 111 receives heat from the heating element 3 through the housing 1 until steam is generated in the first section 111. The steam generated in the first section 111 enters the second section 112. The steam initially entering the second section 112 continues to be heated by the heating element 3 until it enters the third section 113. The steam entering different sections of the third section 113 moves along the third section 113 until it reaches the end of the third section 113. The steam in the two sections of the third section 113 mixes and is discharged through the steam outlet 22. During the movement of the steam along the flow channel 11, it is continuously heated by the heating element 3. And during the movement, some of the steam that does not receive enough heat liquefies. The liquefied steam cannot enter the next section of the flow channel 11, nor can it be discharged through the steam outlet 22, until it is reheated and vaporized by the heating element 3.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
