Description

Technical Field

[0001] This utility model pertains to clothing ironing equipment, specifically relating to an iron capable of evenly releasing steam. Background Technology

[0002] In existing irons, water is vaporized into steam by a vaporization chamber. The steam is then transported through a steam distribution channel to the steam output holes, and finally released out of the iron. Because the steam output holes are distributed along the steam distribution channel, and the vaporization chamber and the steam distribution channel are connected at their rear ends, regardless of whether water is supplied to the vaporization chamber through one or two inlets, the steam is always released from the steam output holes at different times. The pressure and intensity of the steam released from the steam output holes at different locations vary, resulting in poor ironing performance. Utility Model Content

[0003] This invention addresses the shortcomings of existing irons where the vaporization chamber and steam distribution channel are connected at their rear ends, and the steam output holes are distributed in a dispersed manner along the steam distribution channel, resulting in differences in the pressure and intensity of steam released from the steam output holes at different locations. It provides an iron that can release steam evenly.

[0004] To achieve the above objectives, the present invention provides an iron capable of uniformly releasing steam. The iron includes a vaporization chamber that supplies steam to a steam output port via a steam distribution channel. The steam distribution channel is located outside the vaporization chamber, and the steam output port is distributed along the steam distribution channel. The vaporization chamber is characterized by being divided into a front chamber and a rear chamber by a first partition wall. A first drain outlet is provided for the front chamber, and a second drain outlet is provided for the rear chamber. The middle part of the vaporization chamber and the middle part of the steam distribution channel are connected via the first channel.

[0005] The iron delivers vaporized steam from the middle of the vaporization chamber through the first channel to the middle of the steam distribution channel, allowing the steam to flow both forward and backward within the distribution channel. For the same length of steam distribution channel, the path of the steam from the inlet to the outlet is shortened, thereby making the pressure and intensity of the steam released from the steam outlets at different locations more consistent, ensuring better ironing results.

[0006] When the iron vaporizes steam, the first drain outlet supplies water to the front chamber, and the second drain outlet supplies water to the rear chamber. This allows the front and rear chambers of the vaporization chamber to vaporize the supplied water simultaneously, making full use of the heat distributed in the vaporization chamber. This improves both vaporization efficiency and quality, resulting in steam containing fewer tiny water droplets.

[0007] Preferably, the iron includes a soleplate, a peripheral wall extending upward from the soleplate, and a vaporization cap covering the upper edge of the peripheral wall. A vaporization chamber and a steam distribution channel are defined between the soleplate, the peripheral wall, and the vaporization cap. Steam outlet holes are distributed on the soleplate and communicate with the steam distribution channel. A first drain outlet and a second drain outlet are located on the vaporization cap. An electric heating element is arranged inside the soleplate. The electric heating element includes a curved middle section and a first side section and a second side section extending rearward from the middle section. The curved middle section is located at the front of the soleplate and protrudes forward in a curved shape. The first side section and the second side section maintain a distance from each other. The ends of the first side section and the second side section extend rearward and lead out to terminals located outside the peripheral wall from the rear of the soleplate. The peripheral wall extending upward from the soleplate is emphasized to indicate its position; that is, in the assembled state, the peripheral wall extends upward from the soleplate. In a specific structure, the peripheral wall can be formed on the soleplate, on the vaporization cap, or both. Based on this structure, the vaporization chamber is defined as a closed cavity, and the heating element distributes heat as evenly as possible to the base plate, concentrating the heat energy within the vaporization chamber and improving vaporization efficiency and quality. Furthermore, the heating element supplies heat to the steam distribution channel through the base plate, maintaining a high temperature in the steam distribution channel and preserving the steam temperature, further vaporizing any tiny water droplets that may be present in the steam. Additionally, the heating element's supply to the steam distribution channel keeps the environment around the steam outlet hole dry, preventing steam from condensing into water droplets upon exiting the steam outlet hole.

[0008] Preferably, the vaporization chamber is located inside the heating element, and the steam distribution channel is located outside the heating element. The first channel spans the heating element, and the first isolation wall is curved and protrudes forward. A second channel connects the front and rear chambers between the first isolation wall and the heating element. This structure isolates the vaporization chamber and the steam distribution channel by using the heating element as a boundary. Both the vaporization chamber and the steam distribution channel are adjacent to the heating element and thus receive heat, which is beneficial for fully utilizing the heat of the heating element. The curved shape of the first isolation wall can increase the length of the second channel, extending the path for the vaporized steam in the rear chamber to enter the steam distribution channel.

[0009] Preferably, the first drain outlet corresponds to the front part of the front chamber, and the second drain outlet corresponds to the area of ​​the rear chamber surrounded by the first partition wall. Accordingly, water delivered to the vaporization chamber from each drain outlet can be blocked in the corresponding front or rear chamber and thus fully vaporized.

[0010] Preferably, the vaporization area of ​​the front chamber is larger than that of the rear chamber, and the first channel connects the front chamber and the steam distribution channel. Because the curved middle section of the heating element is located at the front of the base plate and protrudes forward in a curved shape, the front chamber can obtain more energy, giving it a greater advantage in vaporizing water into steam compared to the rear chamber. Therefore, this structure can balance the vaporization capabilities of the front and rear chambers.

[0011] Preferably, the middle portion of both the first side section and the second side section has a curved section located in front of the first isolation wall and protruding towards the middle of the base plate. The first channel spans the curved section, and the upper surface of the base plate corresponding to the curved section is raised to form a guide surface. The presence of the curved section allows the heating element to concentrate more heat in the first channel, thereby further heating the steam flowing through the first channel and ensuring that the steam is dry.

[0012] Preferably, the portion of the vaporization cover surrounding the first drain outlet bulges upwards, forming an expansion cavity on the lower side of this bulge. Similarly, the portion of the vaporization cover corresponding to the first channel bulges upwards, forming an expansion section of the first channel on the lower side of this bulge. The expansion cavity provides a larger space for water vaporization, allowing small water droplets that rapidly heat and splash upon hitting the base plate to splash within this larger space, facilitating rapid vaporization. The expansion section, in turn, gives the first channel a larger diameter, allowing steam to flow quickly and smoothly from the vaporization cavity to the steam distribution circuit.

[0013] Preferably, a second isolation wall extends upward along the heating tube on the upper surface of the base plate to isolate the vaporization chamber from the steam distribution channel. The second isolation wall retains the first channel. A discontinuous, meandering wall extends upward along the heating tube on the upper surface of the base plate at the edge of the front chamber, forming a meandering channel connecting the front chamber with the second isolation wall. The meandering wall increases the contact area between the front chamber and the steam, allowing the steam to be heated quickly and flow meanderingly within the front chamber. The meandering channel provides a meandering path for the steam, allowing some of the vaporized steam to be fully heated through its meandering flow within the channel. This facilitates the full and rapid vaporization of water and ensures the drying of the steam.

[0014] Preferably, a steam distribution channel is distributed on each of the left and right sides of the vaporization chamber, and the front ends of the steam distribution channels are connected. This allows the steam output holes to be distributed symmetrically on the bottom plate, which helps to increase the steam distribution area.

[0015] Preferably, the steam distribution channel forms an expansion space corresponding to the first channel. This expansion space is equivalent to a steam storage chamber. When the steam from the vaporization chamber flows through this expansion space in the forward and backward directions of the steam distribution channel, it will not weaken and can maintain its pressure and flow rate. This ensures that the steam output from different steam outlets maintains a consistent pressure, flow rate, and temperature, thus guaranteeing the ironing effect.

[0016] In this invention, the vaporization chamber is divided into a connected front chamber and a rear chamber by a first partition wall. A first drain outlet is provided in the front chamber, and a second drain outlet is provided in the rear chamber. The middle part of the vaporization chamber and the middle part of the steam distribution channel are connected by a first channel. When the iron is working, the vaporized steam is transported from the middle part of the vaporization chamber to the middle part of the steam distribution channel through the first channel. This allows the steam to flow both forward and backward in the steam distribution channel. For the same length of steam distribution channel, the path of the steam from the inlet to the outlet is shortened, thereby making the pressure and intensity of the steam released from the steam outlets at different locations more consistent, ensuring a better ironing effect.

[0017] In this invention, when the iron vaporizes steam, the first drain outlet supplies water to the front chamber, and the second drain outlet supplies water to the rear chamber. This allows the front and rear chambers of the vaporization chamber to vaporize the supplied water simultaneously, making full use of the heat distributed in the vaporization chamber. This improves both vaporization efficiency and quality, resulting in steam containing fewer tiny water droplets. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

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

[0024] Figure 1A complete iron is shown. The iron includes a vaporizing assembly 100 at the bottom and a housing 200 located above the vaporizing assembly. A water reservoir 210 is disposed within the housing 200, and a handle 220 is located on the upper part of the housing 200. When the iron is powered on, water in the water reservoir is supplied to the vaporizing chamber of the vaporizing assembly. The water is vaporized and released within the vaporizing chamber. By holding the handle, the iron can be moved relative to the clothing, allowing steam to be applied to the clothing for ironing.

[0025] In the illustrated structure, the vaporization assembly 100 of the iron includes a vaporization chamber 101 that supplies steam to a steam output port 103 via a steam distribution channel 102. The steam distribution channel 102 is located outside the vaporization chamber 101, and the steam output ports 103 are distributed along the steam distribution channel 102. Furthermore, the vaporization chamber 101 is divided into a front chamber 1011 and a rear chamber 1012 by a first partition wall 112. A first drain outlet 121 is provided for the front chamber 1011, and a second drain outlet 122 is provided for the rear chamber 1012. The middle part of the vaporization chamber 101 and the middle part of the steam distribution channel 102 are connected via a first channel 104.

[0026] Based on the above structure, the iron delivers vaporized steam from the middle part of the vaporization chamber through the first channel to the middle part of the steam distribution channel, so that the steam flows both forward and backward in the steam distribution channel. For the same length of steam distribution channel, the path of steam from the inlet position to the outlet position is shortened, thereby making the pressure and intensity of the steam released from the steam outlets at different positions tend to be consistent, achieving the effect of uniform steam release and ensuring better ironing effect.

[0027] When the iron vaporizes steam, the first drain outlet supplies water to the front chamber, and the second drain outlet supplies water to the rear chamber. This allows the front and rear chambers of the vaporization chamber to vaporize the supplied water simultaneously, making full use of the heat distributed in the vaporization chamber. This improves both vaporization efficiency and quality, resulting in steam containing fewer tiny water droplets.

[0028] The above structure embodies the basic concept of this utility model, enabling the realization of its technical solution. To further improve the clamping and positioning device, based on the above structure, the following preferred technical means can be selected to obtain a better embodiment.

[0029] like Figure 2-4As shown, the vaporization assembly 100 of the iron includes a soleplate 110, a peripheral wall 111 extending upward from the soleplate, and a vaporization cover 120 covering the upper edge of the peripheral wall 111. A vaporization chamber 101 and a steam distribution channel 102 are defined between the soleplate 110, the peripheral wall 111, and the vaporization cover 120. Steam outlet holes 103 are distributed on the soleplate 110 and communicate with the steam distribution channel 102. A first drain outlet 121 and a second drain outlet 122 are located on the vaporization cover 120. Heating elements 130 are arranged inside the soleplate 110, and the heating elements 130 are as follows... Figure 6-7 The diagram shows a curved central section 131 and a first side section 132 and a second side section 133 extending rearward from the central section. The curved central section 131 is located at the front of the base plate and protrudes forward in a curved shape. The first side section 132 and the second side section 133 are spaced apart. The ends of the first side section 132 and the second side section 132 extend rearward and lead out from the rear of the base plate 110 to a terminal 134 located outside the peripheral wall 111. The peripheral wall 111 extending upward from the base plate 110 is emphasized to indicate its position; that is, in the assembled state, the peripheral wall extends upward from the base plate, and the vaporization cap 120 is positioned at the upper end of the peripheral wall 111. In the illustrated structure, the peripheral wall 111 is formed on the base plate. In other embodiments, the peripheral wall may also be formed on the vaporization cap, or both on the base plate and on the vaporization cap. Based on this structure, the vaporization chamber 101 is defined as a closed cavity, and the heating element 130 distributes heat as evenly as possible to the bottom plate, concentrating the heat energy in the vaporization chamber and improving vaporization efficiency and quality. Furthermore, the heating element supplies heat to the steam distribution channel through the bottom plate, maintaining a high temperature in the steam distribution channel and preserving the steam temperature, further vaporizing any tiny water droplets that may be present in the steam. Additionally, the heating element's supply to the steam distribution channel keeps the environment around the steam outlet hole dry, preventing steam from condensing into water droplets upon exiting the steam outlet hole.

[0030] Figure 7 The heating element 130 shown is in Figure 5 The vaporization chamber 101 is located inside the heating element 130, and the steam distribution channel 102 is located outside the heating element 130. A first channel 104 spans the heating element 130. A first insulating wall 112 is curved and protrudes forward. A second channel 105 maintains communication between the first insulating wall 112 and the heating element 130, connecting the front chamber 1011 and the rear chamber 1012. This structure isolates the vaporization chamber 101 and the steam distribution channel 102 with the heating element 130 as the boundary. Both the vaporization chamber 101 and the steam distribution channel 102 are adjacent to the heating element 130 and thus receive heat, facilitating full utilization of the heating element's heat. The curved shape of the first insulating wall 112 increases the length of the second channel 105, extending the path for the vaporized steam in the rear chamber 1011 to enter the steam distribution channel 102.

[0031] like Figure 3As shown, the first drain 121 corresponds to the front part of the front cavity 1011, and the second drain 122 corresponds to the area of ​​the rear cavity 1012 surrounded by the first isolation wall 112. Accordingly, water delivered to the vaporization chamber from each drain can be blocked in the corresponding front or rear cavity and fully vaporized.

[0032] like Figure 3 , Figure 5 As shown, the vaporization area of ​​the front chamber 1011 is larger than that of the rear chamber 1012. This is manifested in the fact that the bottom surface area of ​​the front chamber 1011 is larger than that of the rear chamber 1012. The first channel 104 connects the front chamber 1011 with the steam distribution channel 102. Because the curved middle section 131 of the heating tube 130 is located at the front of the base plate 110 and protrudes forward in a curved shape, the front chamber 1011 can obtain more energy and has a greater advantage than the rear chamber in vaporizing water into steam. Therefore, this structure can balance the vaporization capacity of the front and rear chambers.

[0033] like Figure 7 As shown, both the first side section 132 and the second side section 133 have a curved section 135 located in front of the first isolation wall 112 and protruding towards the center of the base plate 110. The first channel 104 spans the curved section 135, and the upper surface of the base plate 110 corresponding to the curved section 135 is raised to form a guide surface 113. The presence of the curved section 135 allows the heating element to concentrate more heat in the first channel, thereby further heating the steam flowing through the first channel and ensuring that the steam is dry.

[0034] like Figure 4 As shown, the portion of the vaporization cover 120 surrounding the first drain outlet 121 rises upwards, forming an expansion cavity 123 on the lower side of this raised portion. The portion of the vaporization cover 120 corresponding to the first channel 104 also rises upwards, forming an expansion portion 124 of the first channel 104 on the lower side of this raised portion. The expansion cavity 123 provides a larger space for water vaporization, allowing small water droplets that rapidly heat and splash upon hitting the base plate to splash within this larger space, facilitating rapid vaporization. The expansion portion 124 provides a larger diameter for the first channel, allowing steam to flow quickly and smoothly from the vaporization cavity to the steam distribution circuit.

[0035] like Figure 3 , Figure 5As shown, a second isolation wall 14 extends upward along the heating tube 130 on the upper surface of the base plate 110 to isolate the vaporization chamber 101 from the steam distribution channel 102. The second isolation wall 114 has the first channel 104. A discontinuous meandering wall 115 located at the edge of the front chamber 1011 extends upward along the heating tube 130 on the upper surface of the base plate 110. A meandering channel 116 connecting the front chamber 1011 is formed between the meandering wall 115 and the second isolation wall 114. The meandering wall increases the contact area between the front chamber and the steam, allowing the steam to be heated quickly and flow meanderingly in the front chamber. The meandering channel provides a meandering path for the steam, allowing the vaporized steam to be fully heated by the meandering flow in the meandering channel. Accordingly, it is beneficial to fully and quickly vaporize water and ensure the drying of steam.

[0036] like Figure 5 As shown, a steam distribution channel 102 is distributed on each of the left and right sides of the vaporization chamber 101, and the front ends of the two steam distribution channels 102 are connected. This allows the steam output holes to be distributed symmetrically on the bottom plate, which helps to increase the steam distribution area.

[0037] like Figure 5 As shown, the steam distribution channel 102 forms an expansion space 1021 at the location corresponding to the first channel 104. This expansion space is equivalent to a steam storage chamber. When the steam from the vaporization chamber flows through this expansion space in the front and back directions of the steam distribution channel, it will not weaken and can maintain its pressure and flow rate. This ensures that the steam output from different steam outlets maintains the same pressure, flow rate and temperature, thus guaranteeing the ironing effect.
