Ironing apparatus with scale filtering function

Abstract

This utility model discloses an ironing device with a scale-filtering function, belonging to the field of clothing ironing technology. Existing ironing devices have scale recovery chambers and filters located outside the steam generator, resulting in poor ironing performance. This utility model's vaporization chamber includes a front steam chamber and a rear steam chamber. Both the vaporization chamber and the steam distribution circuit are defined within the inner side of the peripheral wall. Both the front and rear steam chambers are defined inside the heating element. A filter is constructed within the vaporization chamber to trap scale particles flowing with the steam. The front steam chamber is located upstream of the filter, and the rear steam chamber is located downstream of the filter. Because the filter is located inside the vaporization chamber rather than outside, the steam flow path is short, preventing cooling, and the pressure loss after steam flows through the filter is small, ensuring the steam pressure output from the steam outlet and guaranteeing ironing performance.

Description

Technical Field

[0001] This utility model relates to clothing ironing technology, specifically to an ironing device with a limescale filtering 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 CN104420152B discloses an ironing appliance including a filter for trapping scale particles transported by steam. It includes a steam generator connected to a steam output port via a steam distribution circuit. The steam distribution circuit includes at least one filter for trapping scale particles transported by the steam flow. The steam distribution circuit of the ironing appliance includes a scale recovery cavity with a scale discharge port, which is sealed by a removable plug accessible from the outside of the appliance. The filter can be removed from the appliance through the scale discharge port. In other words, the scale recovery cavity and filter of this ironing appliance are located outside the steam generator. Steam needs to detour through the steam generator to exit the steam output port via the steam distribution circuit. The steam is cooled as it flows through the filter, affecting the ironing effect. Furthermore, to extend the steam flow path through the filter, and because the filter has a small flow surface, the steam pressure decreases after passing through the filter, resulting in lower steam pressure exiting the steam output port, which also affects the ironing effect. Furthermore, since the scale recovery cavity and filter of the ironing equipment are located outside the steam generator, and in order to place the scale recovery cavity and filter inside the ironing equipment, the ironing equipment becomes larger and more complex in structure. Utility Model Content

[0004] This invention addresses the shortcomings of existing ironing equipment, such as poor ironing performance caused by the scale recovery cavity and filter being located outside the steam generator, by providing an ironing device with scale filtering function.

[0005] To achieve the above objectives, the present invention provides an ironing device with a scale-filtering function, comprising a vaporization chamber, a steam distribution circuit, and a steam output port. The vaporization chamber includes a front steam chamber for receiving incoming water and vaporizing it into steam, and a rear steam chamber connected to the front steam chamber and conveying the steam to the steam output port via the steam distribution circuit. Both the vaporization chamber and the steam distribution circuit are defined within the inner side of a peripheral wall. Both the front and rear steam chambers are defined within the inner side of an electric heating element. A filter is constructed within the vaporization chamber to trap scale particles flowing with the steam. The front steam chamber is located upstream of the filter, and the rear steam chamber is located downstream of the filter.

[0006] When the ironing equipment is working, the front steam chamber vaporizes the delivered water into steam with a certain pressure. The steam then flows in the vaporization chamber and filters out the scale particles generated when it flows through the filter, preventing the scale particles from flowing out of the steam outlet and adhering to the clothes being ironed. Tiny water droplets that are not vaporized in the front steam chamber collide with the filter and are further vaporized. The steam flowing through the filter is then delivered to the steam outlet through the rear steam chamber and steam distribution circuit.

[0007] This ironing device incorporates a filter within the vaporization chamber to trap scale particles carried by the steam, rather than placing the filter outside the vaporization chamber. Furthermore, since both the vaporization chamber and the steam distribution circuit are defined within the peripheral wall, and the front and rear steam chambers of the vaporization chamber are defined within the heating element, the steam from the vaporization chamber, when output to the steam outlet via the steam distribution circuit, does not need to detour outside the steam generator but flows within the peripheral wall. This shortens the flow path, prevents cooling, and minimizes pressure loss after passing through the filter, ensuring the steam pressure output from the steam outlet and guaranteeing the ironing effect.

[0008] This ironing equipment features a filter located within the vaporization chamber, allowing it to be fully heated. This causes tiny water droplets carried by the steam to collide with the filter screen and undergo secondary vaporization, reducing the moisture content in the steam.

[0009] This ironing equipment, because it has a filter inside the vaporization chamber to trap scale particles that flow with the steam, instead of placing the filter outside the vaporization chamber, does not increase the size of the ironing equipment and has a simple and compact structure.

[0010] In a preferred embodiment, the two sides of the rear steam chamber are connected to the steam output port via steam distribution circuits. This is equivalent to configuring two steam distribution circuits to evenly distribute steam to the steam output port.

[0011] In a preferred embodiment, the peripheral wall is provided with an assembly channel for removing the filter from the ironing equipment. This allows the user to remove the filter from the ironing equipment to clean limescale. Furthermore, the assembly channel is a through hole, which facilitates its sealing.

[0012] In a preferred embodiment, the assembly channel is sealed by a plug located on the outer side of the peripheral wall and accessible from outside the ironing device. This prevents steam from leaking out of the assembly channel.

[0013] In a preferred embodiment, the filter is connected to the stopper for easy removal and installation. The filter can be removed by taking the stopper out of the assembly channel, and the filter is installed into the vaporization chamber by sealing the assembly channel with the stopper.

[0014] In a preferred embodiment, a transition channel extends from the assembly channel to the outside of the ironing device, and a plug seals 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.

[0015] In a preferred embodiment, the filter is tubular with filter holes distributed on its wall. One end of the filter is open, facing the front steam chamber, while the other end is closed. This allows all steam to enter the filter through the open end and exit through the filter holes in the tube wall, effectively trapping all scale particles carried by the steam.

[0016] In a preferred embodiment, filter holes are distributed on all four sides of the filter's walls. A flow space is maintained on the outer side of the filter's walls to allow the front-end steam chamber to connect to the steam distribution circuit and steam output port via the filter's inner side, the filter holes, and the flow space. This provides the filter with a large filtration area and flow capacity, enabling the smooth flow of steam through the filter while filtering scale particles, preventing a drop in steam pressure due to the presence of the filter.

[0017] In a preferred embodiment, the front-end steam chamber is connected to the rear-end steam chamber via an outlet, and the filter opening is aligned with the outlet of the front-end steam chamber. This ensures that all steam from the front-end steam chamber enters the filter without overflowing, aiming to completely trap scale particles carried by the steam. Furthermore, the alignment of the filter opening with the outlet of the front-end steam chamber facilitates easy removal and reinstallation of the filter, preventing improper filter assembly.

[0018] In a preferred embodiment, the front steam chamber is located at the front of the vaporization chamber, and the rear steam chamber is located at the rear of the vaporization chamber. The front steam chamber is connected to the rear steam chamber via an outlet, and the outlet is connected to a steam distribution circuit via a filter and the rear steam chamber. Accordingly, the direction of steam flow is defined, causing the steam to flow from front to back within the vaporization chamber, pass through the filter and the rear steam chamber, and then be distributed to the steam output port via the steam distribution circuit.

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.

[0021] 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.

[0022] 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.

[0023] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0024] Figure 1 This invention illustrates a complete ironing device 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 wire to an external power source, the ironing device can be controlled by the user as needed using electrical power. This application aims to improve the bottom unit for filtering scale particles carried by steam during ironing operation; therefore, the invention is described below by detailing the bottom unit.

[0025] like Figure 2-7 As shown, the bottom unit 100 includes a bottom plate 110, a vaporization cover 120, a transition channel 130, and a filter 140. A bent electric heating tube 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.

[0026] Given the above structure, Figure 2-7The bottom unit 100 shown is capable of vaporizing water into steam and guiding the steam flow based on the vaporization chamber 101, steam distribution circuit 102, and steam output port 103. The vaporization chamber 101 includes a front steam chamber 1011 for receiving water from the water tank via the drain outlet 121 and vaporizing it into steam, and a rear steam chamber 1012 connected to the front steam chamber and conveying the steam through the steam distribution circuit 102 to the steam output port 103. Both the vaporization chamber 101 and the steam distribution circuit 102 are defined inside the peripheral wall 112. The front steam chamber 1011 and the rear steam chamber 1012 are both defined inside the heating element 111. A filter 140 is located within the vaporization chamber 101 to trap scale particles flowing with the steam. The front steam chamber 1011 is located upstream of the filter 140, and the rear steam chamber 1012 is located downstream of the filter 140. Among them, the inner side of the peripheral wall 112 refers to the direction surrounded by the peripheral wall, and the inner side of the heating tube 111 refers to the direction surrounded by the heating tube.

[0027] When the ironing device is working, the front steam chamber 1011 vaporizes the supplied water into pressurized steam. The steam flows within the vaporization chamber 101 under pressure. Scale particles carried by the steam are filtered as they pass through the filter 140, preventing them from flowing out of the steam outlet 103 and adhering to the ironed clothing. Furthermore, tiny water droplets that are not vaporized in the front steam chamber 1011 collide with the filter and are further vaporized. The steam flowing through the filter is then transported to the steam outlet 103 via the rear steam chamber 1012 and the steam distribution circuit 102.

[0028] This ironing device incorporates a filter within the vaporization chamber to trap scale particles carried by the steam, rather than placing the filter outside the vaporization chamber. Furthermore, since both the vaporization chamber and the steam distribution circuit are defined within the peripheral wall, and the front and rear steam chambers of the vaporization chamber are defined within the heating element, the steam from the vaporization chamber, when output to the steam outlet via the steam distribution circuit, does not need to detour outside the steam generator but flows within the peripheral wall. This shortens the flow path, prevents cooling, and minimizes pressure loss after passing through the filter, ensuring the steam pressure output from the steam outlet and guaranteeing the ironing effect.

[0029] This ironing equipment features a filter located within the vaporization chamber, allowing it to be fully heated. This causes tiny water droplets carried by the steam to collide with the filter screen and undergo secondary vaporization, reducing the moisture content in the steam.

[0030] This ironing equipment, because it has a filter inside the vaporization chamber to trap scale particles that flow with the steam, instead of placing the filter outside the vaporization chamber, does not increase the size of the ironing equipment and has a simple and compact structure.

[0031] 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.

[0032] In a preferred embodiment, the two sides of the rear steam chamber 1012 are connected to the steam output port 103 via a steam distribution circuit 102. This is equivalent to having a steam distribution circuit on both sides of the vaporization chamber to distribute the steam evenly to the steam output port.

[0033] In another preferred embodiment, the peripheral wall 112 is provided with an assembly channel 113 for removing the filter 140 from the ironing device, allowing the user to remove the filter from the ironing device to clean scale. Furthermore, the assembly channel 113 is a through hole, facilitating its sealing. Further, the assembly channel 113 is sealed by a plug 150 located on the outside of the peripheral wall 112 and accessible from the outside of the ironing device, preventing steam leakage from the assembly channel. Moreover, to facilitate the removal and installation of the filter, the filter 140 is connected to the plug 150; the filter can be removed by removing the plug from the assembly channel, and the filter can be installed into the vaporization chamber by sealing the assembly channel with the plug. Therefore, a handle 160 is connected to the plug 150, allowing the plug and filter to be removed and reinstalled together. Furthermore, a transition channel 130 extends from the assembly channel 113 to the outside of the ironing device, and the plug 150 seals the assembly channel 113 and / or the transition channel 130. The transition channel increases the distance between the assembly channel and the outside of the ironing equipment, which can effectively block heat conduction between the vaporization chamber and the outside of the ironing equipment.

[0034] In the third preferred embodiment, such as Figure 8-10As shown, the filter 140 is tubular with filter holes 141 distributed on its wall. One end of the filter 140 is an opening 142 facing the front steam chamber 1011, while the other end is closed. This allows all steam to enter the filter 140 through the opening 142 and then flow out through the filter holes 141 on the wall, effectively blocking scale particles carried by the steam. Furthermore, filter holes 141 are distributed around the perimeter of the filter 140, and a flow space 104 is maintained on the outer side of the perimeter to allow the front steam chamber 1011 to connect to the steam distribution circuit 102 and the steam outlet 103 via the inner side of the filter 140, the filter holes 141, and the flow space 104. This provides the filter with a large filtration area and flow capacity, enabling the smooth flow of steam through the filter while filtering scale particles, preventing a drop in steam pressure due to the presence of the filter. Furthermore, the front steam chamber 1011 is connected to the rear steam chamber 1012 via the outlet 105, and the filter opening 142 is aligned with the outlet 105 of the front steam chamber. This ensures that all steam from the front steam chamber enters the filter without overflowing, aiming to completely trap scale particles carried by the steam. Moreover, the alignment of the filter opening with the outlet of the front steam chamber facilitates easy removal and reinstallation of the filter, preventing improper assembly. In particular, the vaporization cap and the outlet form a tubular structure, and the filter opening 142 is inserted into the outlet 105 for alignment and sealing, eliminating concerns about improper assembly.

[0035] In the fourth preferred embodiment, the front steam chamber 1011 is located at the front end of the vaporization chamber, and the rear steam chamber 1012 is located at the rear end of the vaporization chamber. The front steam chamber 1011 is connected to the rear steam chamber 1012 via an outlet 105. The outlet 105 is connected to the steam distribution circuit 102 via a filter 140 and the rear steam chamber 1012. Accordingly, the direction of steam flow is defined, causing the steam to flow from front to back in the vaporization chamber, pass through the filter and the rear steam chamber, and then be distributed to the steam output port via the steam distribution circuit.
