Description

Technical Field

[0001] This utility model relates to the technical field of ironing equipment and accessories, and in particular to an ironing soleplate and a steam iron. Background Technology

[0002] Current steam ironing equipment, especially steam irons, typically uses a single internal heating element, primarily for heating the steam-generating chamber to vaporize water, with the steam exiting directly from the bottom. This method is not very effective for ironing clothes or fabrics. Therefore, a soleplate needs to be added to the bottom of the ironing unit, allowing the soleplate to contact the clothes or fabric for ironing. However, this also introduces several problems. First, ironing clothes directly with the soleplate can cause the steam temperature to drop, reducing the effectiveness of steam ironing. Second, dry ironing is not very effective with this design. Third, the amount of steam emitted from the unit is affected by the soleplate temperature. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, an ironing board and a steam iron are provided to overcome at least one of the above-mentioned technical defects.

[0004] The specific technical solution is as follows: An ironing soleplate, adapted for use in steam equipment, characterized in that the ironing soleplate comprises: The main body plate has a vaporization chamber inside, and the vaporization chamber has at least one first steam outlet that opens downward. The base plate is fitted to the lower end face of the main plate and has at least one second steam outlet opposite to the position of the first steam outlet. The cover plate is assembled on the lower end face of the base plate and has multiple third steam outlets to allow the steam formed in the vaporization chamber to be sprayed downwards sequentially through the first steam outlet, the second steam outlet and the third steam outlet; The first electric heating element is embedded in the main body plate and is used to supply heat to the vaporization chamber to vaporize the liquid flow into steam. The second electric heating element is embedded in the base plate to supply heat to the base plate; Furthermore, the steam equipment or the main body plate has a control module that can independently control the working state of the first heating element and the second heating element, so that the ironing plate can spray steam without being limited by the plate temperature and heat the plate regardless of the working state inside the vaporization chamber.

[0005] Preferably, the main body plate has an upper cover plate for sealing the vaporization chamber. The vaporization chamber is divided by ribs into a normal vaporization chamber, an explosive vaporization chamber arranged around the normal vaporization chamber, and a steam conveying chamber arranged around the explosive vaporization chamber. The normal vaporization chamber is also provided with a first liquid flow blocking rib and a second liquid flow blocking rib along the steam flow direction to prevent liquid from flowing directly into the steam conveying chamber.

[0006] Preferably, the upper cover plate is also provided with a first water inlet hole and equipped with a first water inlet connector, and a second water inlet hole and equipped with a second water inlet connector, wherein the first water inlet hole is directly opposite to the beginning of the steam flow path in the ordinary vaporization chamber, and the second water inlet hole is directly opposite to the beginning of the steam flow path in the explosion vaporization chamber.

[0007] Better The first liquid flow blocking rib is configured with a structure that is high in the middle and low on both sides, which causes the liquid flow to be blocked at the front of the ordinary vaporization chamber and allows steam to flow through the gap between the two sides of the first liquid flow blocking rib and the upper cover plate. The second liquid flow blocking rib is configured with a low middle and high sides, which causes the liquid flow to be blocked in the cavity between the first liquid flow blocking rib and the second liquid flow blocking rib, while allowing steam to flow through the gap between the middle position of the second liquid flow blocking rib and the upper cover plate.

[0008] Preferably, the cavity between the first and second flow blocking ribs also has multiple protruding ribs, forming a labyrinthine flow channel.

[0009] Preferably, two first through holes are arranged at the end position along the steam flow direction in the steam conveying chamber, and four second through holes are arranged in a mirror image along the steam flow path of the steam conveying chamber. The cross-sectional area of ​​the first through holes is larger than that of the second through holes, and the first through holes and the second through holes together serve as the first steam outlet.

[0010] Preferably, the base plate has a third through hole opposite to the first through hole and a fourth through hole of the same number and opposite to the second through hole, and the third through hole and the fourth through hole together serve as the second steam outlet.

[0011] Preferably, the cladding plate has multiple third steam outlets arranged in an array, and a steam flow gap is formed between the cladding plate and the bottom plate. The third steam outlets on the cladding plate are distributed as multiple fifth through holes located in the middle and multiple sixth through holes arranged around the fifth through holes. The diameter of the sixth through holes gradually increases from the inside to the outside.

[0012] Preferably, NTCs are also attached to the end face of the base plate facing the main plate and the end face of the main plate facing the base plate, respectively, to detect the temperature in real time and feed it back to the control module to automatically adjust the working power of the first heating element and the second heating element.

[0014] The beneficial effects of the above technical solution are as follows: (1) The ironing base plate is adapted to the steam equipment, including the main plate, base plate, wrap plate, first heating tube, and second heating tube. The steam equipment or the main plate has a control module that can independently control the working state of the first heating tube and the second heating tube, so that the two heating tubes can be independently controlled to rise and fall within the preset range. In the dry ironing mode, the base plate temperature can be controlled independently. At the same time, the first heating tube can maintain its working state and spray a small amount of steam or maintain a state that can spray steam at any time. In the steam ironing mode, steam can be sprayed without being limited by the base plate temperature, allowing a large amount of steam to be sprayed even when the base plate is at a low temperature, so that the user experience is better.

[0015] (2) The design of the first liquid flow blocking rib and the second liquid flow blocking rib allows the liquid flow to be blocked in the ordinary vaporization chamber while allowing steam to pass through, which can effectively improve the vaporization rate.

[0016] (3) The third steam outlet on the cover plate is distributed as multiple fifth through holes in the middle and multiple sixth through holes arranged around the fifth through holes. The diameter of the sixth through holes gradually increases from the inside to the outside, so that the steam ejected from the cover plate is more uniform. Attached Figure Description

[0025] 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 5 The top-to-bottom direction shown on the paper is the front-to-back direction in the following embodiments, and the direction perpendicular to the paper and inward is the top-to-bottom direction in the following embodiments.

[0026] Example 1, See Figures 1 to 8 As shown in the illustration, the ironing soleplate provided in this embodiment is adapted to a steam equipment and includes: The main plate 1 has a vaporization chamber inside, and the vaporization chamber has at least one first steam outlet 11 that opens in the downward direction; The base plate 2 is assembled on the lower end face of the main body plate 1 and has at least one second steam outlet 21 opposite to the position of the first steam outlet 11; The cover plate 3 is assembled on the lower end face of the base plate 2 and has multiple third steam outlets 31 to allow the steam formed in the vaporization chamber to be sprayed downward sequentially through the first steam outlet 11, the second steam outlet 21 and the third steam outlet 31. The first electric heating tube 4 is embedded in the main body plate 1 to supply heat to the vaporization chamber to vaporize the liquid flow into steam; The second electric heating element 5 is embedded in the base plate 2 to supply heat to the base plate 2; Furthermore, the steam device or the main body plate 1 has a control module that can independently control the working state of the first heating element 4 and the second heating element 5, so that the ironing plate 2 can spray steam without being limited by the temperature of the plate 2, and heat the plate 2 regardless of the working state in the vaporization chamber.

[0027] Based on the above technical solution, the ironing soleplate 2 provided in this embodiment is adapted to a steam device, including a main body plate 1, a soleplate 2, a cover plate 3, a first heating element 4, and a second heating element 5. The steam device or the main body plate 1 has a control module that can independently control the working state of the first heating element 4 and the second heating element 5, so that both heating elements can be independently controlled to rise and fall within a preset temperature range. In dry ironing mode, the temperature of the soleplate 2 can be controlled independently, while the first heating element 4 can remain in working state to spray a small amount of steam or remain in a state where it can spray steam at any time. In steam ironing mode, steam can be sprayed without being limited by the temperature of the soleplate 2, allowing a large amount of steam to be sprayed even when the soleplate 2 is at a low temperature, thus providing a better user experience.

[0028] In a preferred embodiment, specifically as follows: Figure 2 , Figure 4 , Figure 5As shown, the main body plate 1 has an upper cover plate 6 for sealing the vaporization chamber. The vaporization chamber is divided by ribs into a normal vaporization chamber 12, an explosive vaporization chamber 13 arranged around the normal vaporization chamber 12, and a steam conveying chamber 14 arranged around the explosive vaporization chamber 13. The normal vaporization chamber 12 also has a first liquid flow blocking rib 15 and a second liquid flow blocking rib 16 formed along the steam flow direction to prevent liquid from directly flowing into the steam conveying chamber 14. Furthermore, the upper cover plate 6 also has a first water inlet hole and a first water inlet connector 7, and a second water inlet hole and a second water inlet connector 8. The first water inlet hole is directly opposite the beginning of the steam flow path in the normal vaporization chamber 12, and the second water inlet hole is directly opposite the beginning of the steam flow path in the explosive vaporization chamber.

[0029] As a further preferred embodiment, the first liquid flow blocking rib 15 is configured with a high center and low sides, causing the liquid flow to be blocked at the front of the ordinary vaporization chamber 12 while allowing steam to flow through the gaps between the two sides of the first liquid flow blocking rib 15 and the upper cover plate 6. Furthermore, the second liquid flow blocking rib 16 is configured with a low center and high sides, causing the liquid flow to be blocked within the cavity between the first liquid flow blocking rib 15 and the second liquid flow blocking rib 16, while allowing steam to flow through the gap between the middle position of the second liquid flow blocking rib 16 and the upper cover plate 6. Furthermore, the cavity between the first liquid flow blocking rib 15 and the second liquid flow blocking rib 16 also has multiple protruding ribs 19 forming a labyrinthine flow channel, so that the liquid overflowing into the cavity is further vaporized, increasing the vaporization length.

[0030] In a preferred embodiment, combined with Figure 6 As shown, two first through holes 17 are arranged at the end position along the steam flow direction in the steam conveying chamber 14, and four second through holes 18 are arranged mirror-imagely along the steam flow path of the steam conveying chamber 14. The cross-sectional area of ​​the first through holes 17 is larger than that of the second through holes 18, and the first through holes 17 and the second through holes 18 together serve as the first steam outlet 11. Furthermore, the bottom plate 2 has a third through hole 22 opposite to the position of the first through holes 17, and a fourth through hole 23 of the same number and position opposite to the second through holes 18, and the third through holes 22 and the fourth through holes 23 together serve as the second steam outlet 21.

[0031] As a further preferred embodiment, combined with Figure 7 and Figure 8 As shown, multiple third steam outlets 31 are formed on the cover plate 3 in an array. A steam flow gap is formed between the cover plate 3 and the bottom plate 2. The third steam outlets 31 on the cover plate 3 are distributed as multiple fifth through holes 32 located in the middle and multiple sixth through holes 33 arranged around the fifth through holes 32. In the direction from the inside to the outside, the diameter of the sixth through holes 33 gradually increases so that the steam ejected from the cover plate 3 is more uniform.

[0032] In a preferred embodiment, NTC9 (i.e., negative temperature coefficient thermistor) is respectively attached to the end face of the base plate 2 facing the main plate 1 and the end face of the main plate 1 facing the base plate 2, so as to detect the temperature in real time and feed it back to the control module to automatically adjust the working power of the first heating tube 4 and the second heating tube 5.

[0033] NTC is widely used in ironing products, so it will not be elaborated here. In addition, the above-mentioned electrical components are electrically connected by wires.

[0034] Example 2, This embodiment provides a steam iron having an ironing soleplate 2 as described in Embodiment 1 above, and a control module electrically connected to a first heating element 4 and a second heating element 5 within the main body of the steam iron. This allows for independent control of the two heating elements.

[0035] In practical applications, the steam chamber and soleplate 2 operate independently. The second heating element 5 embedded in soleplate 2 preheats faster and its temperature is adjustable. The first heating element 4 in the corresponding steam chamber maintains a high constant temperature, allowing the steam chamber to release steam at any time. Dry ironing and steam ironing operate independently. In both modes, the heating element in the steam chamber maintains a constant temperature and continues heating. Once soleplate 2 reaches the set temperature, it shuts off, activates, and stops heating within the set range. Simultaneously, the steam chamber and soleplate 2 heating elements each have NTCs to control different set temperatures and have different thermal protection mechanisms.

[0036] In dry ironing mode, the temperature of the soleplate 2 can be adjusted according to needs, and steam can be released at any time. The steam volume can be adjusted between 1g and 32g using the control buttons on the steam iron, without dripping water. In steam ironing mode, the first heating element 4 maintains a high and constant temperature, allowing the steam chamber to release steam at any time. This overcomes the problems of existing technologies with only a single heating element, which cannot independently adjust the temperature of the soleplate 2, cannot release steam when the soleplate 2 is too cold, and cannot iron directly without a soleplate 2.

[0037] 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.
