Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a noise reduction structure and a steam generator. Background Technology

[0002] Currently, when using steam generators, condensation in the steam channel can obstruct steam output, causing the internal pressure of the steam generator to rise and further generate noise. Taking a vertical garment steamer as an example, when the condensation in the steam pipe head flows back into the hot pot, the condensation accumulates in the steam pipe, thus obstructing steam output. This leads to a surge in pressure inside the hot pot, causing the water to boil violently and surge to the lower end of the steam pipe, resulting in noticeable noise and even interrupting steam output, affecting the user experience. Utility Model Content

[0003] The main purpose of this invention is to propose a noise reduction structure and a steam generating device, which aims to solve the problem of excessive noise generated in the steam channel due to the increase in gas pressure inside the steam generating chamber during the use of the steam generating device.

[0004] To achieve the above objectives, this utility model proposes a noise reduction structure for use in the steam channel of a steam generator. The noise reduction structure includes:

[0005] The main body extends along a first direction and has a steam passage extending through it in the first direction, one end of which is an air inlet and the other end is an air outlet; and...

[0006] A blocking part is provided in the steam passage. The blocking part has a first end and a second end. The first end is disposed adjacent to the inner wall of the steam passage, and the second end extends toward the air inlet end. The second end of the blocking part defines an air outlet. An air passage hole is provided on the blocking part between the first end and the second end.

[0007] In one embodiment, the blocking portion is arranged gradually towards the center of the steam passage from its first end to its second end.

[0008] In one embodiment, the blocking portion includes a plurality of blocking ribs distributed circumferentially along the steam passage. The first end of each blocking rib is connected to the steam passage, and the second end extends toward the air inlet. There is a gap between two adjacent blocking ribs to define the air passage.

[0009] In one embodiment, the plurality of the blocking ribs are arranged from their first end toward the center of the steam passage; and / or,

[0010] The blocking rib is tapered from its first end to its second end.

[0011] In one embodiment, the dimension of the blocking rib in the first direction is H, where H ≥ 5 mm.

[0012] In one embodiment, the sum of the projected areas of the vent and the pore on the cross-section of the steam passage is S1, and the projected area of ​​the blocking part on the cross-section of the steam passage is S2, where 0.5 ≤ S1 / S2 ≤ 1.2.

[0013] In one embodiment, the material of the barrier portion includes a hydrophobic material.

[0014] In one embodiment, the first direction is the vertical direction, the air inlet is the lower end of the main body, and the air outlet is the upper end of the main body.

[0015] This utility model also proposes a steam generating device, including a noise reduction structure;

[0016] The noise reduction structure includes:

[0017] The main body extends along a first direction and has a steam passage extending through it in the first direction, one end of which is an air inlet and the other end is an air outlet; and...

[0018] A blocking part is provided in the steam passage. The blocking part has a first end and a second end. The first end is disposed adjacent to the inner wall of the steam passage, and the second end extends toward the air inlet end. The second end of the blocking part defines an air outlet. An air passage hole is provided on the blocking part between the first end and the second end.

[0019] In one embodiment, the steam generating device includes a garment steamer, which includes a hot pot and a steam pipe. The hot pot is equipped with a heating element for heating water in the hot pot to generate steam. One end of the steam pipe is connected to the upper end of the hot pot to exhaust the steam from the hot pot.

[0020] The noise reduction structure is located between the hot pot and the air duct.

[0021] In the technical solution of this utility model, a noise reduction structure is provided on the steam channel of the steam generator. When the condensate flows back, the condensate flows out of the steam channel and moves along the inner wall of the main body from the outlet end to the inlet end. It continues to move along the first direction along the blocking part until the condensate moves to the second end of the blocking part and drips into the steam generating chamber of the steam generator after accumulating at the second end. In other words, by providing a noise reduction structure on the steam channel of the steam generator, this utility model ensures that the condensate flows out of the steam channel when it flows back, preventing the condensate from accumulating in the steam channel and further blocking the steam outlet. In addition, since the blocking part is provided with an air outlet and an air hole, the body of the noise reduction structure will not block the normal steam outlet. Furthermore, even if the gas pressure inside the steam generator increases, since the second end of the blocking part extends towards the inlet end, when the bubbles rise to contact the blocking part, the second end of the blocking part will burst. Thus, the problem of excessive noise caused by the increase in gas pressure inside the steam generating chamber is solved. Attached Figure Description

[0035] Currently, when using steam generators, condensation in the steam channel can obstruct steam output, causing the internal pressure of the steam generator to rise and further generate noise. Taking a vertical garment steamer as an example, when the condensation in the steam pipe head flows back into the hot pot, the condensation accumulates in the steam pipe, thus obstructing steam output. This leads to a surge in pressure inside the hot pot, causing the water to boil violently and surge to the lower end of the steam pipe, resulting in noticeable noise and even interrupting steam output, affecting the user experience.

[0036] This utility model proposes a noise reduction structure 100.

[0037] Please see Figures 1 to 3 In one embodiment of the present invention, the noise reduction structure 100 is used on the steam channel of a steam generator 200. The noise reduction structure 100 includes a main body 101 and a blocking part 102. The main body 101 extends along a first direction and forms a steam passage 1011 that extends through the steam passage 1011 in the first direction. One end of the steam passage 1011 is an air inlet and the other end is an air outlet. The blocking part 102 is disposed in the steam passage 1011 and has a first end and a second end. The first end is disposed adjacent to the inner wall of the steam passage 1011, and the second end extends toward the air inlet. The second end of the blocking part 102 defines an air outlet 1021. An air vent 1022 is provided on the blocking part 102 between the first end and the second end.

[0038] In the technical solution of this utility model, a noise reduction structure 100 is provided on the steam channel of the steam generator 200. When the condensate flows back, the condensate flows out of the steam channel and moves along the inner wall of the main body 101 from the outlet end to the inlet end, and continues to move along the first direction along the blocking part 102 until the condensate moves to the second end of the blocking part 102, and after accumulating at the second end, drips into the steam generating chamber of the steam generator 200. That is to say, this utility model, by providing a noise reduction structure 100 on the steam channel of the steam generator 200, makes the condensate flow more smoothly and efficiently. When condensate flows back, it will flow out of the steam channel, preventing condensate from accumulating in the steam channel and further blocking the steam outlet. In addition, since the blocking part 102 is provided with an air outlet 1021 and an air hole 1022, the body of the noise reduction structure 100 will not block the normal steam outlet. Furthermore, even if the gas pressure inside the steam generator 200 increases, since the second end of the blocking part 102 extends towards the air inlet, when the bubble rises to contact the blocking part 102, the second end of the blocking part 102 will burst. Thus, the problem of excessive noise caused by the increase in gas pressure inside the steam generator cavity is solved.

[0039] Please see Figures 2 to 4 In an embodiment of this invention, the second end of the blocking portion 102 extends toward the air inlet end and out of the main body 101. That is, since the second end extends out of the main body 101, the condensate collected on the second end is located outside the steam passage 1011 of the main body 101, meaning the condensate will not be located inside the steam passage 1011, thus having a smaller impact on the steam output. It should be noted that this invention does not limit the position of the second end of the blocking portion 102. Specifically, in another embodiment of this invention, the main body 101 is a tubular structure extending along a first direction, and the blocking portion 102 is located inside the main body 101. In this embodiment, although condensate may accumulate in the steam passage 1011 and thus affect the steam output, simply setting the cross-sectional area of ​​the main body 101 to gradually expand in the first direction effectively increases the size of the steam passage 1011, thereby reducing the obstruction of steam output by condensate in the steam passage 1011. Furthermore, since the main body 101 is gradually expanded in the first direction, it is not necessary to adjust the size of the existing steam passage to achieve a sealed fit with the steam passage, allowing condensate to flow smoothly from the inner wall of the main body 101 along the first direction.

[0040] It should be noted that this utility model does not limit the specific form of the second end. In another embodiment of this utility model, the second end is generally funnel-shaped, and the funnel wall is provided with a plurality of vent holes 1022. In this embodiment, the condensate flows along the inner wall of the funnel shape and finally flows out through the vent hole 1021 at the funnel opening, and the steam exits through the vent hole 1021 and the vent holes 1022 on the funnel wall.

[0041] Within the steam generator 200, tiny bubbles may rise with the steam. The bursting of these bubbles could splash water into the steam passage 1011 located inside the blocking portion 102, posing a risk of noise. To avoid this, in this embodiment of the invention, the blocking portion 102 is arranged gradually towards the center of the steam passage 1011 from its first end to its second end. In other words, because multiple blocking portions 102 are arranged gradually towards the air inlet, it effectively prevents water from splashing into the steam passage 1011 located inside the blocking portion 102 due to the bursting of bubbles outside the blocking portion 102.

[0042] In practice, if the second end is funnel-shaped and the funnel wall is provided with an air passage 1022, the air output efficiency of this solution cannot meet the requirements. To improve the air output efficiency, it is necessary to increase the area of ​​the air passage 1021 and / or the air passage 1022. In the embodiment of this utility model, the blocking part 102 includes a plurality of blocking ribs 103, which are distributed circumferentially along the steam passage 1011. The first end of each blocking rib 103 is connected to the steam passage 1011, and the second end extends toward the air inlet end. There is a gap between two adjacent blocking ribs 103 to define the air passage 1022. That is to say, because there is a gap between two adjacent blocking ribs 103, the air passage 1022 is defined as an elongated hole, which greatly increases the air output area of ​​the air passage 1021 and the air passage 1022, making the steam output smoother and less likely to be blocked by the condensate.

[0043] In embodiments of this invention, multiple blocking ribs 103 are arranged gradually towards the center of the steam passage 1011 from their first end to their second end. This effectively prevents water from splashing into the steam passage 1011 located inside the blocking ribs 103 due to the bursting of bubbles located outside the blocking ribs 103. Furthermore, since the second end also needs to have a certain bubble-breaking function, the contact area between the second end and the bubble cannot be too large. Please refer to [reference needed]. Figure 4 In this embodiment of the invention, the blocking rib 103 is tapered from its first end to its second end. That is, the blocking rib 103 tapers towards the air inlet end, thus ensuring a small contact area between the second end and the water bubble, improving the bubble-breaking ability of the second end, and also providing a certain shielding area near the steam channel, making it less likely for water droplets from the bursting of the water bubble to splash into the steam channel. Furthermore, the tapering of the second end ensures that the size of the air outlet 1021 is not too small, thereby making the steam outlet smoother. It should be noted that the above embodiments can be used selectively or simultaneously, and this invention does not impose any limitations on this.

[0044] It should be noted that the length of the blocking rib 103 in the first direction has certain requirements. If the length of the blocking rib 103 is too long, it may extend below the water surface, failing to break bubbles and affecting the efficiency of steam output. If the length of the blocking rib 103 is too short, it may not be able to block splashing water or guide condensate along the blocking rib 103, resulting in poor steam output and thus losing all its function. Therefore, in the embodiment of this utility model, the dimension of the blocking rib 103 in the first direction is H, where H ≥ 5mm. It should be noted that this utility model only limits the minimum length of the blocking rib 103 to ensure that the noise reduction structure 100 has all its functions. As for the maximum length of the blocking rib 103, this utility model does not limit it; its length can be adjusted according to the actual steam generator 200 used, so that the blocking rib 103 does not extend below the water surface.

[0045] It should be noted that, in order to ensure that the air output efficiency of the noise reduction structure 100 meets the requirements, there are certain requirements for the ratio of the air output area of ​​the air outlet and the air outlet hole to the blocking area blocked by the blocking part 102. Please refer to [link / reference needed]. Figure 5 In this embodiment of the present invention, the sum of the projected areas of the vent 1021 and the vent hole 1022 on the cross-section of the steam passage 1011 is S1, and the projected area of ​​the blocking part 102 on the cross-section of the steam passage 1011 is S2, where 0.5 ≤ S1 / S2 ≤ 1.2. That is, the blocking area covered by the blocking part 102 is S2. By limiting the ratio of S1 / S2, it is ensured that the noise reduction structure 100, while fulfilling its noise reduction function, does not affect the normal steam output. It should be noted that when the ratio of S1 / S2 is too low, the output area of ​​the vent and the vent hole is too small, which will affect the normal steam output. When the ratio of S1 / S2 is too large, it indicates that the blocking area of ​​the blocking part 102 is too small. In this case, the blocking part 102 may not be able to properly block water splashes or even properly break bubbles, thus failing to prevent the liquid level from rising and failing to achieve the noise reduction effect.

[0046] Since the condensate will fall into the steam generating chamber through the blocking part 102, it is necessary to ensure that the condensate falls off the blocking part 102 as quickly as possible. Therefore, in this embodiment of the invention, the material of the blocking part 102 includes a hydrophobic material. It should be noted that this invention does not limit the specific form of the hydrophobic material. In this embodiment of the invention, the blocking part 102 is made of polytetrafluoroethylene (PTFE), which can both prevent condensate from adhering to it and ensure smooth passage of steam.

[0047] In an embodiment of this utility model, the first direction is the vertical direction, the air inlet is the lower end of the main body 101, and the air outlet is the upper end of the main body 101. When the steam is generated from inside the steam generating chamber, the steam moves vertically upward. Therefore, the blocking part 102 is configured to extend in the vertical direction, consistent with the direction of steam movement, so that the steam can be discharged more smoothly.

[0048] This utility model also proposes a steam generating device 200, which includes a noise reduction structure 100. The specific structure of the noise reduction structure 100 is as described in the above embodiments. Since this steam generating device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The noise reduction structure 100 includes a main body 101 and a blocking part 102. The main body 101 extends along a first direction and forms a steam passage 1011 that extends through the first direction. One end of the steam passage 1011 is an air inlet and the other end is an air outlet. The blocking part 102 is disposed in the steam passage 1011 and has a first end and a second end. The first end is disposed adjacent to the inner wall of the steam passage 1011, and the second end extends toward the air inlet. The second end of the blocking part 102 defines an air outlet 1021. An air vent 1022 is provided on the blocking part 102 between the first end and the second end.

[0049] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the steam generating device 200 includes a garment steamer, which includes a hot pot 201 and a steam duct 202. The hot pot 201 contains a heating element 203 for heating water to generate steam. One end of the steam duct 202 connects to the upper end of the hot pot 201 to vent the steam. The noise reduction structure 100 is located between the hot pot 201 and the steam duct 202. It should be noted that this utility model does not limit the specific location of the noise reduction structure 100. In one embodiment, the noise reduction structure 100 is located at the upper end of the hot pot 201. In another embodiment, the noise reduction structure 100 is located at the lower end of the steam duct 202. As long as the noise reduction structure 100 is located between the hot pot 201 and the steam duct 202, i.e., within the steam channel of the garment steamer, it is acceptable.

[0050] In an embodiment of this utility model, the garment steamer further includes a connector 204 for sealingly connecting the hot pot 201 and the air duct 202. When the garment steamer is working normally, the water in the hot pot 201 boils and the water level gradually rises. When the condensate flows back, the condensate flows out of the air duct 202 and moves along the inner wall of the main body 101 from the air outlet to the air inlet. It continues to move along the first direction along the blocking part 102 until the condensate reaches the second end of the blocking part 102 and drips into the steam generating chamber in the hot pot 201 after accumulating at the second end. In addition, since the second end of the blocking part 102 extends towards the air inlet, when the water level rises, the second end of the blocking part 102 will break bubbles, thereby effectively preventing the water level from rising further and thus preventing the water level from rising to a position that affects the air duct 202.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
