Description

Technical Field

[0001] This utility model relates to the field of clothing care equipment technology, and in particular to an iron and an ironing device with a secondary vaporization function. Background Technology

[0002] Garment care equipment, especially irons, generally consists of two parts: a base and an iron. To improve the steam vaporization rate, a boiler is typically built into both the base and the iron to achieve secondary vaporization. The steam inside the iron flows downwards through the soleplate. In the initial operating state or when power is suddenly increased, the high-pressure, high-velocity, and high-temperature steam generated in the boiler easily and quickly flows out through the soleplate for pressure relief. However, afterwards, the internal pressure is lower, resulting in a smaller steam flow rate and uneven steam ejection rate and quantity. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, an iron and an ironing device with secondary vaporization function are provided to avoid the rapid flow of steam out of the iron under high pressure and high flow rate, avoid clothing or fabric being exposed to a large amount of steam and becoming too wet and hot, and avoid the problem of low pressure in the gap after instantaneous pressure relief and low amount of steam flowing out of the iron afterward, while not affecting the flow of low-flow rate steam, thereby overcoming at least one of the above-mentioned technical defects.

[0004] The specific technical solution is as follows:

[0005] An iron includes a housing and a first evaporator at least partially disposed within the housing;

[0006] Below the first evaporator, there is a bottom plate that extends downward through the shell. A gap is formed between the bottom plate and the bottom surface of the first evaporator to allow steam to flow. The steam outlet of the first evaporator is connected to the gap to allow steam to enter the gap and flow along the gap.

[0007] At least one first steam outlet area and at least one second steam outlet area are formed on the base plate, and the minimum distance between the second steam outlet area and the bottom surface of the first evaporator is less than the minimum distance between the first steam outlet area and the bottom surface of the first evaporator, so that the high-velocity steam is blocked by the second steam outlet area and slows down the rate at which it flows out of the iron, while allowing the low-velocity steam to flow out of the iron at a preset rate range.

[0008] Preferably, on the plane formed by the upper surface of the base plate, the first steam outlet area and the second steam outlet area are arranged at intervals in a second direction, and the second direction is not parallel to the first direction.

[0009] Preferably, the second direction is perpendicular to the first direction.

[0010] Preferably, the base plate is provided with a first steam outlet area and two second steam outlet areas, and the two second steam outlet areas are distributed on both sides of the first steam outlet area.

[0011] Preferably, the first steam outlet region includes at least one first steam outlet hole, and the second steam outlet region includes at least one second steam outlet hole and a barrier rib formed on the base plate and surrounding the second steam outlet hole in at least a first direction.

[0012] Preferably, the diameter of the first steam outlet is larger than the diameter of the second steam outlet.

[0013] Preferably, the bottom plate also has an annular rib that protrudes upwards and extends upwards to abut against the bottom surface of the first evaporator, forming a closed gap.

[0014] Preferably, the barrier rib is configured in a "C" shape and connected to the inner wall of the annular rib to surround the second steam outlet in two directions, while being surrounded by the annular rib in other directions.

[0015] Preferably, the second steam outlet area includes a raised portion formed on the base plate, and the raised portion is provided with at least one second steam outlet hole.

[0016] This utility model also proposes an ironing device with a secondary vaporization function, including a base, an iron as described above, and a pipe connecting the two for passing steam. A second evaporator is provided in the base, and the pipe connects the first evaporator and the second evaporator.

[0017] The second evaporator has a water splash structure located directly below the water inlet in the steam generating chamber, causing the clean water entering the steam generating chamber through the water inlet to be passively splashed in all directions.

[0018] The beneficial effects of the above technical solution are as follows:

[0019] The iron includes a shell, a first evaporator, and a soleplate. A gap is formed between the soleplate and the first evaporator. Within the gap, a first steam outlet area and a second steam outlet area with different spacing are formed on the soleplate. This allows the high-pressure, high-velocity steam ejected from the first evaporator to be slowed down by the second steam outlet area during certain working states, especially the initial start-up state. This maintains a certain steam pressure within the gap, preventing the steam from flowing out of the iron too quickly under high pressure and high velocity conditions. This avoids the problem of clothes or fabrics being exposed to a large amount of steam instantly, resulting in excessive moisture and overheating. It also avoids the problem of low pressure within the gap after a sudden pressure drop, which would result in a low amount of steam flowing out of the iron subsequently. At the same time, it does not affect the flow of low-velocity steam, resulting in better ironing effect and a longer product lifespan. Attached Figure Description

[0026] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 1 The up-down direction shown on the paper is the up-down direction in this embodiment.

[0027] Example 1,

[0028] See Figures 1 to 3 As shown in the figure, the iron provided in this embodiment includes a housing 1 and a first evaporator 2 at least partially disposed within the housing 1; wherein,

[0029] The first evaporator 2 is provided with a bottom plate 3 that extends downward through the shell 1 at least partially. A gap 4 for steam to flow is formed between the bottom plate 3 and the bottom surface of the first evaporator 2. The steam outlet 15 of the first evaporator 2 is connected to the gap 4 to allow steam to enter the gap 4 and flow along the gap 4.

[0030] At least one first steam outlet area 5 and at least one second steam outlet area 6 are formed on the base plate 3, and the minimum distance between the second steam outlet area 6 and the bottom surface of the first evaporator 2 is less than the minimum distance between the first steam outlet area 5 and the bottom surface of the first evaporator 2, so that the high-velocity steam is blocked by the second steam outlet area 6 and the rate of steam flowing out of the iron is slowed down, while allowing the low-velocity steam to flow out of the iron at a preset rate range.

[0031] Based on the above technical solution, the iron includes a shell 1, a first evaporator 2, and a soleplate 3. A gap 4 is formed between the soleplate 3 and the first evaporator 2. Within the gap 4, a first steam outlet area 5 and a second steam outlet area 6 with different spacing are formed on the soleplate 3. This allows the high-pressure, high-velocity steam ejected from the first evaporator 2 to be slowed down by the second steam outlet area 6 during some working states, especially the initial opening state. This maintains a certain steam pressure within the gap 4, preventing the steam from flowing out of the iron too quickly under high pressure and high velocity conditions. This also prevents clothes or fabrics from being exposed to a large amount of steam instantly, resulting in excessive moisture and overheating. Furthermore, it avoids the problem of low pressure within the gap 4 after instantaneous pressure relief, which would lead to a low amount of steam flowing out of the iron subsequently. At the same time, it does not affect the flow of low-velocity steam, resulting in better ironing effect and a longer product lifespan.

[0032] In a preferred embodiment, specifically as follows: Figure 2 and Figure 3 As shown, on the plane formed by the upper surface of the base plate 3, within the gap 4, along the steam flow direction is the first direction X, and the first steam outlet region 5 and the second steam outlet region 6 are arranged at intervals in the second direction Y, and the second direction Y is not parallel to the first direction X. Preferably, the second direction Y is perpendicular to the first direction X.

[0033] As a further preferred embodiment, the base plate 3 is provided with a first steam outlet area 5 and two second steam outlet areas 6, and the two second steam outlet areas 6 are distributed on both sides of the first steam outlet area 5.

[0034] Obviously, the number and arrangement of the first steam outlet area 5 and the second steam outlet area 6 can adopt various schemes and are not limited to the above. They can even be designed to be arranged at intervals in the first direction X, which can also achieve the above technical purpose.

[0035] In a preferred embodiment, the first steam outlet region 5 includes at least one first steam outlet hole 7, and the second steam outlet region 6 includes at least one second steam outlet hole 8 and a baffle rib 9 formed on the base plate 3 and surrounding the second steam outlet hole 8 at least in the first direction X. In this embodiment, the minimum distance between the first steam outlet region 5 and the bottom surface of the first evaporator 2 is the distance of the gap 4, and the minimum distance between the second steam outlet region 6 and the bottom surface of the first evaporator 2 is the distance between the upper edge of the baffle rib 9 and the bottom surface of the first evaporator 2. Further, the diameter of the first steam outlet hole 7 is larger than the diameter of the second steam outlet hole 8. In this embodiment, the number of first steam outlet holes 7 is one, and the number of second steam outlet holes 8 is two, which can be determined based on the steam outlet rate requirements and is not limited thereto.

[0036] As a further preferred embodiment, an annular rib 10 is formed protruding upward on the base plate 3, and the annular rib 10 extends upward to abut against the bottom surface of the first evaporator 2, forming a closed gap 4. Obviously, this gap 4 can also be designed as an open gap. In the first direction X within the gap 4, the steam outlet 15 is arranged at the starting position along the steam flow direction, and the first steam outlet area 5 and the second steam outlet area 6 are arranged at the ending position along the steam flow direction. Further, the barrier rib 9 is configured as a "C" shape and connects to the inner wall of the annular rib 10 to surround the second steam outlet 8 in two directions, while the other directions are surrounded by the annular rib 10. However, it is obvious that the barrier rib 9 can also be directly set as a "I" shape or an "O" shape, and is not limited to this.

[0037] As another optional embodiment, the second steam outlet region 6 includes a raised portion formed on the base plate 3, and at least one second steam outlet hole 8 is provided on the raised portion. Alternatively, the first steam outlet region 5 and the second steam outlet region 6 may be formed by forming a wavy barrier arc surface on the base plate 3, and are not limited thereto.

[0038] Example 2,

[0039] See Figures 4 to 6 As shown in the figure, the ironing device with secondary vaporization function provided in this embodiment includes a base 11, an iron as described in Embodiment 1, and a pipe connecting the two for passing steam. A second evaporator 12 is provided inside the base 11, and the pipe connects the first evaporator 2 and the second evaporator 12; wherein,

[0040] The second evaporator 12 has a water splashing structure 13 located directly below the water inlet connector 14 in the steam generating chamber, which causes the clean water entering the steam generating chamber through the water inlet connector 14 to be passively splashed in all directions.

[0041] The ironing equipment with secondary vaporization function includes a base 11, an iron, pipes, a second evaporator 12, and a water splashing structure 13, which causes the clean water entering the second evaporator 12 from the water tank to be splashed and dispersed, thereby improving the vaporization efficiency of the second evaporator 12.

[0042] In a preferred embodiment, specifically as follows: Figure 6 As shown, the water splashing structure 13 is a cross-shaped rib formed on the bottom surface of the steam generating chamber, and the middle of the cross-shaped rib extends further upward into a columnar protrusion to achieve a better water splashing effect.

[0043] In addition, a labyrinthine flow channel is formed in the steam generating chamber to increase the steam vaporization time. The second evaporator 12 is also provided with a steam outlet connector, which is connected to the steam inlet of the first evaporator 2 through a pipeline to perform secondary vaporization in the first evaporator 2 and enter the gap 4 from the steam outlet 15. This is a design logic that is easy for those skilled in the art to understand, so it is omitted here.

[0044] Furthermore, the aforementioned preset rate range is preferably 30-60 g / min. High-flow-rate steam is suitable for rates exceeding 70 g / min, and its instantaneous flow rate after entering gap 4 from the first evaporator 2 after initial steam startup can easily reach over 80 g / min. Low-flow-rate steam is suitable for flow rates of 10-70 g / min. This flow rate range will vary based on the evaporator volume, gap 4 size, and outlet hole inner diameter, and is not absolute.

[0045] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
