Description

Technical Field

[0001] This utility model relates to the field of clothing care technology, and in particular to a heater for a clothing care machine that provides uniform steam. Background Technology

[0002] Clothing care machines primarily use a heating element to heat water to generate steam, which is then used to iron or disinfect clothing. A common method involves injecting water into an evaporator, heating it with a heating element, and then venting the steam.

[0003] In related technologies, the heater that generates steam in a garment care machine typically includes a heated water tank with a heating tube inside. After the heating tube heats the water, steam is generated and then discharged. This results in a mixture of water and steam, which causes the flow rate to be high in the middle of the heater and low at the edges, leading to inconsistent steam discharge speed and uneven steam discharge. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a garment care machine heater with uniform steam, which divides the heating chamber in the steam generating box into two sections by setting a steam baffle and guides the steam with different guide vanes, so as to separate water and steam and produce uniform steam.

[0005] The technical solution adopted by this utility model to solve its problem is: A garment care machine heater for uniform steam distribution, comprising, A steam generator box includes a heating element, a heating chamber, a steam baffle, a water inlet, and a steam outlet. The steam baffle is disposed in the heating chamber and divides the heating chamber into a first section and a second section, which are distributed along the height of the steam generator box. A conductive channel is provided on the steam baffle, extending along the height of the steam generator. The conductive channel includes a first end and a second end, the first end communicating with the first section and the second end communicating with the second section. The water inlet communicates with the first section, and the steam outlet communicates with the second section. The first cavity is provided with a first guide vane and a second guide vane. The first guide vane includes two first guide segments and two second guide segments. One end of the two first guide segments surrounds the first side of the first end and is connected to each other. The other end of the two first guide segments is connected to the two second guide segments. A second guide vane is provided between the inner side of each second guide segment and each first guide segment. A first guide interval is formed between the second guide vane and the first guide segment. A second guide interval is formed between the second guide vane and the second guide segment. A third guide interval is formed between the outer side of each second guide segment and the inner wall of the corresponding side of the second cavity. The first guide interval, the second guide interval, and the third guide interval are sequentially connected. The third guide interval is connected to the second side of the first end. The first side of the first end is close to the water inlet, and the second side of the first end is far away from the water inlet.

[0006] As an optional implementation, a plurality of first flow-slowing baffles are provided within the first flow-guiding interval, and the plurality of first flow-slowing baffles are distributed at intervals in the direction of water flow.

[0007] As an optional implementation, a plurality of second flow-slowing baffles are provided within the second flow-guiding interval, and the plurality of second flow-slowing baffles are spaced apart in the direction of water flow.

[0008] As an optional implementation, a plurality of third flow-slowing baffles are provided within the third flow-guiding interval, and the plurality of third flow-slowing baffles are spaced apart in the direction of water flow.

[0009] In one optional implementation, the second cavity section is provided with a first baffle and two second baffles. The first baffle includes a first baffle segment and two second baffle segments. The first baffle segment surrounds a first side of the conductive channel, and the two second baffle segments are connected to both sides of the first baffle segment. One side of each of the two second baffle segments is spaced from the end wall of the second cavity section to form a first baffle interval, and the other side of each of the two second baffle segments is spaced from one side of each of the two second baffles to form a second baffle interval. The other side of each of the two second baffles is spaced from the end wall of the second cavity section to form a discharge interval, and a conductive interval is formed between the two second baffles. The conductive interval is conductive to the discharge interval. The steam discharge hole is conductive to the discharge interval. The first baffle interval is conductive to the second side of the second end. The first side of the second end is close to the steam discharge hole, and the second side of the second end is away from the steam discharge hole.

[0010] As an optional implementation, the second flow-blocking interval is provided with a plurality of third flow-blocking plates, and the plurality of third flow-blocking plates are spaced apart.

[0011] As an optional implementation, the heating element is disposed within the steam baffle; the heating element includes a heating resistor.

[0012] As an optional implementation, the steam generator box includes a heating shell, a first cover plate, and a second cover plate. The heating shell is provided with a heating chamber and a steam baffle. The first cover plate is connected to the heating shell and covers the first chamber section.

[0014] As an optional implementation, the water inlet and the steam outlet are located at opposite ends of the steam generator box; the water inlet is provided with a water inlet pipe, and multiple steam outlets are provided.

[0015] In summary, this utility model has the following technical effects: In this way, the water flow introduced through the inlet can be guided through the meandering flow intervals formed by the first and second guide vanes in the first cavity section, rather than being directly introduced into the second end through the first end of the conduction channel. This allows the water flow to spread out in the first cavity section, so that the water flow can fully contact the heating element in the steam generator box, resulting in higher heating efficiency and rapid steam generation.

[0016] Furthermore, the generated steam can flow during the meandering process, and can be fully separated from the water flow to achieve water-gas separation. In this way, the steam that reaches the second side of the first end of the channel is fully separated from the water flow, thus improving the steam output efficiency. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] See Figures 1-5 This utility model discloses a heater for a garment care machine that provides uniform steam, including a steam generating box 10. The steam generating box 10 is provided with a heating element, a heating chamber, a steam baffle, a water inlet 11, and a steam outlet 16. The heating element can heat the heating chamber. The steam baffle is disposed in the heating chamber, thus dividing the heating chamber into a first chamber segment 101 and a second chamber segment 109. The first chamber segment 101 and the second chamber segment 109 are distributed in the height direction of the steam generating box 10, that is, the first chamber segment 101 and the second chamber segment 109 can be distributed vertically, or the second chamber segment 109 and the first chamber segment 101 can be distributed vertically.

[0027] A conductive channel 102 is provided on the steam baffle. The conductive channel 102 extends along the height direction of the steam generator. The conductive channel 102 includes a first end and a second end. The first end is connected to the first cavity section 101, and the second end is connected to the second cavity section 109. The water inlet 11 is connected to the first cavity section 101, and the steam outlet hole 16 is connected to the second cavity section 109.

[0028] Specifically, a first guide vane 14 and a second guide vane 15 are disposed within the first cavity 101. The first guide vane 14 includes two first guide segments 141 and two second guide segments 142. One end of each of the two first guide segments 141 surrounds the first side 1021 of the first end and is connected to each other. The other end of each of the two first guide segments 141 is connected to the two second guide segments 142. A second guide vane 15 is disposed between the inner side of each second guide segment 142 and each first guide segment 141. The second guide vane 15 and the first guide segment 141 are connected to each other. A first flow guiding interval 103 is formed between the second flow guiding plate 15 and the second flow guiding segment 142; a second flow guiding interval 104 is formed between the outer side of each second flow guiding segment 142 and the inner wall of the corresponding side of the second cavity segment 109; the first flow guiding interval 103, the second flow guiding interval 104 and the third flow guiding interval 105 are sequentially connected; the third flow guiding interval 105 is connected to the second side 1022 of the first end; the first side 1021 of the first end is close to the inlet 11, and the second side 1022 of the first end is far away from the inlet 11.

[0029] Based on the above structure, when using the uniform steam heating element of this utility model for garment care machines, the steam outlet 16 of the steam generator box 10 is connected to the ironing plate of the garment care machine, and the water inlet 11 of the steam generator box 10 is connected to the water inlet pipe. The water inlet 11 can be introduced into the first cavity section 101. Since the second cavity section 109 is connected to the first cavity section 101 through the connecting channel 102, and the first end of the connecting channel to the first cavity section 101 near the water inlet 11 is blocked by the first guide segment 141, the water entering through the water inlet 11 will be guided by the first guide interval 103 formed by the first guide segment 141 and the second guide plate 15, and enter the second cavity section 109. The water is guided by the second flow interval 104 formed by the guide vane 15 and the second flow segment 142, and then guided to the second side 1022 of the first end of the conduction channel 102 through the third flow interval 105 between the second flow segment 142 and the inner wall of the first cavity 101. In this way, the water flow introduced through the inlet 11 can be guided through the meandering flow intervals formed by the first guide vane 14 and the second guide vane 15 in the first cavity 101, instead of being directly introduced into the second end through the first end of the conduction channel 102. This allows the water flow to spread out in the first cavity 101, and the water flow can fully contact the heating element in the steam generator box 10, resulting in higher heating efficiency and rapid steam generation.

[0030] Furthermore, the generated steam can flow during the meandering process, and can be fully separated from the water flow to achieve water-gas separation. In this way, the steam that reaches the second side 1022 position of the first end of the conduction channel 102 is fully separated from the water flow, thus improving the steam output efficiency.

[0031] As an optional implementation, a plurality of first flow-slowing baffles 1031 are provided in the first flow-guiding interval 103. The plurality of first flow-slowing baffles 1031 are distributed at intervals in the direction of water flow. In this way, the water flowing into the first flow-guiding interval 103 has multiple first flow-slowing baffles 1031 during the flow process, which slows down the water flow speed, makes the water flow evenly distributed, and makes the heating surface fully contact the liquid, thereby improving the continuity of steam generation. At the same time, it can also reduce splashing and turbulence of the water flow during the flow process, reduce the mixing of steam and water, and make the output steam purer.

[0032] Similarly, multiple second flow-slowing baffles 1041 are provided in the second flow-guiding interval 104. The multiple second flow-slowing baffles 1041 are distributed at intervals in the water flow direction. The water flow entering the second flow-guiding interval 104 through the first flow-guiding interval 103 can also be further slowed down and blocked by the multiple second flow-slowing baffles 1041, which slows down the water flow velocity and makes the water flow distribution more uniform. The water flow heating and steam flow outlet path is blocked and guided by multiple first flow-slowing baffles 1031 and multiple second flow-slowing baffles 1041 continuously distributed, so that the heating surface is in full contact with the liquid and the continuity of steam generation is improved.

[0033] More specifically, a plurality of third flow-slowing baffles 1051 are further provided in the third flow-guiding interval 105. The plurality of third flow-slowing baffles 1051 are distributed at intervals in the direction of water flow. Since the third flow-guiding interval 105 is connected to the second side 1022 of the first end of the guiding channel 102, the steam generated in the first cavity 101 is concentrated in the third flow-guiding interval 105 and guided through the second side 1022 of the first end. Therefore, the distribution of a plurality of third flow-slowing baffles 1051 in the third flow-guiding interval 105 can further reduce the mixing of steam and water, so that water can be retained in the first cavity 101, and purer steam is guided to the second end through the second side 1022 of the first end.

[0034] As an optional implementation, in the relevant implementation structure, a first baffle plate 17 and two second baffle plates 18 may also be provided in the second cavity section 109. The first baffle plate 17 includes a first baffle segment 171 and two second baffle segments 172. Similarly, the first baffle segment 171 surrounds the first side of the guiding channel, and the two second baffle segments 172 are connected to both sides of the first baffle segment 171. One side of the two second baffle segments 172 is spaced from the end wall of the second cavity section 109 to form a first baffle interval 106, and the other side of the two second baffle segments 172... A second flow-blocking interval 107 is formed by a gap between one side of the two second flow-blocking plates 18 and one side of the second flow-blocking plates 18; an outlet interval 108 is formed between the other side of the two second flow-blocking plates 18 and the end wall of the second cavity section 109; a conduction interval 181 is formed between the two second flow-blocking plates 18, and the conduction interval 181 is in communication with the outlet interval 108; the steam outlet hole 16 is in communication with the outlet interval 108; the first flow-blocking interval 106 is in communication with the second side 1024 of the second end; the first side 1023 of the second end is close to the steam outlet hole 16, and the second side 1024 of the second end is far away from the steam outlet hole 16.

[0035] Based on this structure, steam is guided from the first end of the conduction channel 102 to the second end. Since the first side of the second end near the steam outlet 16 is surrounded by the first baffle segment 171, when the steam reaches the second end, it is blocked and guided by the first baffle segment 171. It flows through the second side 1024 of the second end to the first baffle gap 106 between the second baffle segment 172 and the end wall of the second cavity 109, and then enters the second baffle gap 107. Due to the blocking effect of the two second baffle plates 18, it does not flow directly to the steam outlet 16, but instead flows through the two second baffle plates 18. The steam is guided through the conduction interval 181 to the outlet interval 108, and then through the outlet interval 108 to multiple steam outlet holes 16 for outlet. In this way, after the steam enters the second cavity section 109, it is also guided by the detour and through-flow intervals 106, 107 and 108 formed by the first baffle plate 17 and the second baffle plate 18, forming a detour outlet path. This intercepts liquid water droplets entrained in the steam multiple times, making the steam drier. In this process, further water-gas separation of the steam is achieved, and the outlet steam is purer.

[0036] As an optional implementation, multiple third baffles 1071 can be provided in the second baffle interval 107, spaced apart. This distribution of multiple third baffles 1071 along the steam outlet path slows down the steam outlet speed, thus balancing the steam pressure and making the steam outlet process more stable, avoiding safety hazards caused by excessive local pressure. Furthermore, it can extend the residence time of steam in the channel, allowing incompletely vaporized liquid to fully vaporize, thereby improving steam utilization.

[0037] As an optional implementation, a heating element can be provided inside the steam baffle. The heating element includes a heating resistor, which is distributed between the first cavity 101 and the second cavity 109. Since the first guide vane 14 and the second guide vane 15 are distributed in the first cavity 101, the water flow can be guided to be evenly distributed in the first cavity 101 to form a meandering flow path. Therefore, the water can fully contact the heating resistor in the steam baffle, increase the heating area, and generate steam at a higher rate.

[0038] The generated steam is guided from the first end to the second end. Since the second cavity 109 is equipped with the first baffle 17 and the second baffle 18, the steam flow rate can be slowed down, and water and gas separation can be achieved in the steam outflow path. The heating resistor installed in the steam baffle can also heat and evaporate the water droplets retained in the second cavity 109 at the same time, that is, the steam outlet cavity can also be heated to improve the steam utilization rate.

[0039] As an optional implementation, the steam generator box 10 includes a heating shell 13, a first cover plate 131, and a second cover plate 132. The heating shell 13 is provided with a heating chamber and a steam baffle. The first cover plate 131 is connected to the heating shell 13 and covers the first cavity section 101. The second cover plate 132 is connected to the heating shell 13 and covers the second cavity section 109. In this way, the heating shell 13 can be processed separately, and then the first cover plate 131 and the second cover plate 132 can be assembled onto the heating shell 13 with screws or bolts, which facilitates the maintenance of the interior of the heating shell 13. After the steam generator box 10 has been used for a period of time, the first cover plate 131 and the second cover plate 132 can also be removed for regular cleaning of scale and other substances, reducing the impact of scale and other substances on the internal water flow or steam flow.

[0040] As an optional implementation, a temperature detection structure is provided inside the heating cavity. This temperature detection structure can be a temperature sensor, such as an NTC detector, used to detect the temperature inside the heating cavity in order to control the heating temperature.

[0041] As an optional implementation, the water inlet 11 and the steam outlet 16 are located at opposite ends of the steam generator box 10. This ensures that the water inlet pipe's inlet structure and the steam outlet's outlet structure are located at opposite ends of the steam generator box 10, preventing pipe interference caused by concentrating at one end. Specifically, the water inlet 11 is equipped with an inlet pipe for easy pipe connection, while multiple steam outlets 16 are provided for higher steam output efficiency.

[0042] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
