Description

Technical Field

[0001] This utility model relates to clothing ironing technology, specifically to an ironing device with a descaling function. Background Technology

[0002] Steam ironing equipment, such as irons, produces limescale during operation. Limescale deposits in the equipment, blockage of steam vents, and being carried by steam onto clothing can all negatively impact ironing.

[0003] Patent document CN117396646A discloses an iron including a scale removal device that can be removably inserted into an evaporation chamber. The removal device includes an elongated oval member with a cross-section much smaller than the cross-section of the evaporation chamber, and this member is equipped with a mechanical removal element adapted to contact the surface of the evaporation chamber. This removes any scale residue formed on the lower surface while the removal device is being removed from and / or inserted into the evaporation chamber. However, because the mechanical removal element is adapted to contact the surface of the evaporation chamber, a portion of the evaporation chamber surface is blocked by the mechanical removal element, preventing water delivered to the evaporation chamber from dripping or splashing onto the entire surface, thus affecting the vaporization rate. Furthermore, the mechanical removal element has difficulty contacting all surfaces of the evaporation chamber, therefore only removing scale from localized areas accessible to the mechanical removal element. Therefore, removing scale formed on the lower surface simultaneously by removing and / or inserting the removal device from the evaporation chamber is limited and cumbersome. Utility Model Content

[0004] This invention addresses the limitations and cumbersome operation of existing irons that remove scale formed on the lower surface while simultaneously removing it from and / or inserting a removal device into the evaporation chamber. It provides an ironing device with a scale removal function.

[0005] To achieve the above objectives, the present invention provides an ironing device with a descaling function, which includes a connected vaporization chamber, a steam distribution circuit, and a steam output port. The device is characterized in that the vaporization chamber and the steam distribution circuit are both defined on the inner side of the peripheral wall, and a scale-accumulating component extending forward and backward and suspended in the vaporization chamber is arranged in the vaporization chamber. The peripheral wall is provided with an assembly channel for removing the scale-accumulating component from the vaporization chamber.

[0006] This ironing device features a suspended, scale-collecting component that extends forward and backward within the vaporization chamber, allowing the lower surface of the chamber to be fully exposed to receive and vaporize dripping and splashing water, thus increasing the vaporization speed. The scale particles generated during vaporization, especially those carried by the steam, accumulate on the surface of the scale-collecting component. Users simply need to remove the component from the vaporization chamber and clean the scale particles from its surface. Since cleaning the scale-collecting component is done outside the ironing device, it is much easier.

[0007] Because the scale buildup component of this ironing device is suspended in the vaporization chamber, its temperature will be slightly lower than the temperature of the lower surface of the vaporization chamber. In particular, the heat from the lower surface of the vaporization chamber will not be directly conducted to the scale buildup component. When water drips or splashes onto the scale buildup component, it will not explode and vaporize as it would when dripping or splashing onto the lower surface of the vaporization chamber, which is conducive to the accumulation of scale on the surface of the scale buildup component.

[0008] In a preferred embodiment, the scale-accumulating component includes a head at its front end, the head having a bottom surface with distributed flow-diverting holes. The head and the distributed flow-diverting holes have a large surface area. Moreover, the head, located at the front end of the scale-accumulating component, is closer to the core area of ​​vaporization in the vaporization chamber, which facilitates the accumulation of scale particles.

[0009] In a preferred embodiment, the head includes a rim extending upward from the bottom edge, with a recess formed on the inner side of the rim and notches distributed along the rim.

[0010] In a preferred embodiment, the scale-accumulating member includes a wing extending rearward from the head, the wing having at least one of the following structures: ribs, grooves, and holes. This increases the surface area of ​​the scale-accumulating member, enabling it to fully contact the flowing steam and allowing scale particles carried by the steam to accumulate on the surface of the scale-accumulating member.

[0011] In a preferred embodiment, at least one side of the wing is provided with a longitudinal rib extending in the front-rear direction. The longitudinal rib can increase the surface area of ​​the dirt-accumulating component, and also help to increase the rigidity and strength of the dirt-accumulating component, ensuring that the dirt-accumulating component is not easily deformed.

[0012] In a preferred embodiment, the wing includes a front wing and a rear wing. The front wing has several transverse ribs intersecting the longitudinal ribs, forming a scale accumulation zone between adjacent transverse ribs. Through holes are distributed in the wing corresponding to the scale accumulation zone. The transverse ribs and through holes increase the surface area of ​​the scale-accumulating component, thereby increasing its scale accumulation capacity. They also promote the meandering flow of steam, allowing sufficient time for scale particles in the steam to accumulate on the component. Furthermore, they facilitate scale accumulation in any direction on the component, such as on the surface facing forward of the transverse ribs or on the surface facing backward. The transverse ribs also increase the strength of the scale-accumulating component, while the through holes reduce its weight.

[0013] In a preferred embodiment, the longitudinal and transverse ribs are distributed on both sides of the front wing, and the transverse ribs on both sides of the front wing are inclined in opposite directions. This further increases the strength and scale-accumulating capacity of the scale-accumulating component. The opposite inclination of the transverse ribs on both sides of the front wing increases steam turbulence, which is beneficial for the deposition of scale particles.

[0014] In a preferred embodiment, there are two steam distribution circuits located on either side of the vaporization chamber. These circuits communicate with the vaporization chamber via lateral flow ports, and the rear wing section is situated between the corresponding lateral flow ports. The two steam distribution circuits facilitate the distribution of steam to the steam output port. The rear wing section, situated between the corresponding lateral flow ports, facilitates the diversion of steam from the vaporization chamber to the steam distribution circuits. In particular, the rear wing section lacks transverse ribs, which increases the steam flow velocity at this location and avoids the narrowing of the opening between the vaporization chamber and the steam distribution circuits due to the presence of transverse ribs, ensuring smooth steam flow at this connection point.

[0015] In a preferred embodiment, the vaporization chamber has a water inlet, and the head is located below the water inlet to divert water flowing down from the inlet. When water droplets delivered to the vaporization chamber fall onto the head, it facilitates both the diversion of the delivered water and the accumulation of scale. Furthermore, when water droplets fall onto the head, they are briefly retained and preheated, thereby reducing the temperature difference between the water and the lower surface of the vaporization chamber, making the water easier to vaporize. The vaporized water also contains fewer tiny water droplets, reducing the moisture content in the steam and improving steam quality. The recessed area extends the retention time of the water droplets on the head, ensuring sufficient preheating.

[0016] In a preferred embodiment, the self-assembly channel extends to the outside of the ironing device via a transition channel. A plug, accessible from the outside of the ironing device, is positioned at the rear end of the descaling component, sealing the assembly channel and / or the transition channel. The transition channel increases the distance between the assembly channel and the outside of the ironing device, effectively blocking heat conduction between the vaporization chamber and the outside of the ironing device.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0020] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Among them, "upper" and "lower," "left" and "right," and "front" and "rear" are opposite directions.

[0021] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0022] Figure 1 A complete ironing apparatus according to the present invention is shown, comprising a bottom unit 100 and a housing 200 mounted above the bottom unit. The housing 200 integrates a water tank 210, a handle 220, and an electrical wire (not shown) extending from a cable conduit 230. By connecting the electrical wire to an external power source, the ironing apparatus can be operated by the user as needed using electrical power. In this application, the aim is to improve the bottom unit for filtering limescale particles that flow with the steam during the operation of the ironing apparatus; therefore, the invention is described below by detailing the bottom unit.

[0023] like Figure 2-4 As shown, the bottom unit 100 includes a bottom plate 110, a vaporization cover 120, a transition channel 130, and a scale buildup component 170. A bent heating element 111 is embedded in the bottom plate 110 for heating the bottom plate. The bottom plate 110 has an upwardly extending peripheral wall 112, grooves adjacent to the peripheral wall located on the inner side of the peripheral wall, and recesses located on the inner side of the grooves. The vaporization cover 120 is sealed to the bottom plate 110, covering the grooves and recesses, forming a steam distribution circuit 102 at the corresponding groove location and a vaporization chamber 101 at the corresponding recess location. Wherein, as... Figure 2 As shown, steam output holes 103 are also distributed on the base plate. The outer end of the steam output hole 103 is exposed on the bottom surface of the base plate 110, and the inner end of the steam output hole 103 is exposed in the steam distribution circuit 102.

[0024] Given the above structure, Figure 2-4 The bottom unit 100 shown, based on the vaporization chamber 101, steam distribution circuit 102, and steam outlet 103, is capable of vaporizing water into steam and guiding steam flow. Both the vaporization chamber 101 and the steam distribution circuit 102 are defined inside the peripheral wall 112. A scale buildup member 170 extending longitudinally and suspended within the vaporization chamber 101 is arranged therein. The peripheral wall 112 is provided with an assembly channel 113 for removing the scale buildup member 170 from the vaporization chamber. Figure 4 In order to highlight the positional relationship between the scale buildup component 170 and the base plate, the scale buildup component 170 is represented by a solid line, and the base plate 110 is represented by a dashed line.

[0025] This ironing device allows the scale-accumulating component to extend back and forth within the vaporization chamber and suspend itself, exposing the entire lower surface of the chamber to receive dripping and splashing water and vaporize it, thus increasing the vaporization speed. The scale particles generated during vaporization, especially those carried by the steam, accumulate on the surface of the scale-accumulating component. Users can simply remove the component from the vaporization chamber to clean the scale particles. Since cleaning the scale surface is done outside the ironing device, it is easier, and cleaning methods include, but are not limited to, tapping, bending, and scraping the component.

[0026] Because the scale buildup component of this ironing device is suspended in the vaporization chamber, its temperature will be slightly lower than that of the lower surface of the vaporization chamber. In particular, the heat from the lower surface of the vaporization chamber will not be directly conducted to the scale buildup component. When water drips or splashes onto the scale buildup component, it will not explode and vaporize as rapidly as when it drips or splashes onto the lower surface of the vaporization chamber, which is conducive to the accumulation of scale on the surface of the scale buildup component.

[0027] The above structure represents the most basic embodiment of the ironing equipment. To further enhance the ironing equipment's functionality and effectiveness, the following technical means can be used to optimize the ironing equipment and obtain a better embodiment.

[0028] like Figure 5-8 As shown, in a preferred embodiment, the scale-accumulating component 170 includes a head 171 located at its front end. The head 171 includes a bottom surface 1711 and a perimeter 1713 extending upward from the edge of the bottom surface. The bottom surface 1711 has distributed diversion holes 1712, and the perimeter 1713 has a recess 1714 formed on its inner side, and notches 1715 distributed on its perimeter 1713. The head 171 and the distributed diversion holes 1712 and notches 1715 give the head a large surface area. Moreover, the head is located at the front end of the scale-accumulating component, closer to the core area of ​​vaporization in the vaporization chamber, which is beneficial for the accumulation of scale particles.

[0029] like Figure 5-8 As shown, in a preferred embodiment, the scale buildup member 170 includes a wing 172 extending rearward from a head 171, the wing 172 having ribs and holes. This increases the surface area of ​​the scale buildup member, allowing for sufficient contact with flowing steam and enabling scale particles carried by the steam to accumulate on the surface of the scale buildup member. In other embodiments, grooves may also be provided on the wing.

[0030] like Figure 5-8 As shown, in a preferred embodiment, longitudinal ribs 1723 extending in the front-to-back direction are provided on the upper and lower sides of the wing 172. These longitudinal ribs increase the surface area of ​​the dirt-accumulating component and also help increase its rigidity and strength, ensuring that the component is not easily deformed. In other embodiments, the wing can be vertical, thus providing longitudinal ribs extending in the front-to-back direction on the left and right sides of the wing.

[0031] like Figure 5-8 As shown, in a preferred embodiment, the wing 172 includes a front wing 1721 and a rear wing 1722. The front wing 1721 has several transverse ribs 1724 intersecting the longitudinal ribs, and a scale accumulation area 1725 is formed between adjacent transverse ribs 1724. The wing 172 (especially the wing corresponding to the scale accumulation area 1725) has through holes 1726. The transverse ribs 1724 and the through holes 1726 can increase the surface area of ​​the scale accumulation member 170, increase the scale accumulation capacity of the scale accumulation member, and also promote the meandering flow of steam, allowing scale particles in the steam sufficient time to accumulate on the scale accumulation member. It also facilitates the accumulation of scale particles in any position on the scale accumulation member, both on the surface facing forward of the transverse ribs and on the surface facing backward of the transverse ribs. The transverse ribs can also increase the strength of the scale accumulation member, while the through holes can reduce the weight of the scale accumulation member.

[0032] like Figure 5-8 As shown, in the preferred embodiment, longitudinal ribs 1723 and transverse ribs 1724 are distributed on both sides of the front wing 1721, and the transverse ribs on both sides of the front wing are inclined in opposite directions. This further increases the strength and scale-accumulating capacity of the scale-accumulating component. The opposite inclination of the transverse ribs on both sides of the front wing increases steam turbulence, which is beneficial for the deposition of scale particles.

[0033] like Figure 5-8 As shown, in a preferred embodiment, there are two steam distribution circuits 102 located on both sides of the vaporization chamber 101. The steam distribution circuits 102 are connected to the vaporization chamber 101 via lateral flow ports 104. The rear wing portion 1722 is located between the corresponding lateral flow ports 104, facilitating the diversion of steam from the vaporization chamber to the steam distribution circuits. The two steam distribution circuits 102 facilitate the distribution of steam to the steam output port 103. In particular, the rear wing portion does not have transverse ribs, which helps increase the steam flow velocity at this location and avoids the narrowing of the opening at the connection between the vaporization chamber and the steam distribution circuit due to the presence of transverse ribs, allowing for smooth steam flow at this connection point.

[0034] like Figure 5-8 As shown, in a preferred embodiment, the vaporization chamber 101 has a water inlet 121, and a head 171 located below the water inlet 121 for diverting water flowing down from the water inlet. When water droplets delivered to the vaporization chamber fall onto the head, it facilitates both diversion of the delivered water and the accumulation of scale. Moreover, when water droplets delivered to the vaporization chamber fall onto the head, they are briefly retained and preheated, thereby reducing the temperature difference between the water and the lower surface of the vaporization chamber, making the water easier to vaporize. The vaporized water contains fewer tiny water droplets, reducing the moisture content in the steam and improving the steam quality. When water droplets fall onto the head, the recess can prolong the time the water stays there, thus ensuring sufficient preheating.

[0035] like Figure 5-8 As shown, in a preferred embodiment, a transition channel 130 extends from the self-assembly channel 113 to the outside of the ironing device. A plug 150, accessible from the outside of the ironing device, is disposed at the rear end of the build-up component 170. The plug 150 seals the assembly channel 113 and / or the transition channel 130 to prevent steam leakage from the assembly channel. The transition channel 130 increases the distance between the assembly channel 113 and the outside of the ironing device, effectively blocking heat conduction between the vaporization chamber and the outside of the ironing device. Furthermore, to facilitate the removal and insertion of the build-up component, a handle 160 is connected to the plug 150. The handle 160 allows the plug 150 and the build-up component 170 to be disassembled and reassembled together.
