Description

Technical Field

[0001] The invention belongs to the technical field of ironing equipment and relates to a steam generating device with an inner frame and ironing equipment. Background Art

[0002] An existing ironing device generates steam by heating water through a steam generating device, and the steam is ejected from the steam outlet of the panel to achieve steam ironing. The steam generating device includes a heating tube, a boiler and a boiler cover. The boiler cover is covered on top of the boiler. The boiler and the boiler cover are usually combined together by riveting or screwing. The heating tube is buried in the boiler. The heat generated by the heating tube when it is powered on can be quickly transferred to the boiler, but cannot be quickly transferred to the boiler cover. This makes the temperature of the boiler body wall and the boiler cover wall inconsistent. When the ironing device is used vertically, when water enters the furnace cavity and flow channel of the boiler for heating, the steaming effect is acceptable. However, when the ironing device is tilted at a large angle or used upside down, the water will flow to the boiler cover, so that the heat provided by the heating tube cannot fully and quickly steam the water, thereby affecting the steam formation rate and greatly reducing the steam dryness.

DETAILED DESCRIPTION

[0022] The following will further describe the specific implementation of the present invention in combination with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] This embodiment provides an ironing device, specifically a steam brush, which can be used for ironing clothes. It is a specific application of the innovative solution of the present invention on a steam brush. The innovative solution of the present invention can also be applied to other ironing devices such as a split ironing machine.

[0024] like Figure 1-5 As shown, the ironing device includes a nozzle 10 and a handle 20. A steam generator 11 is arranged in the nozzle 10, and a panel 12 is arranged on the nozzle 10. A water tank 21 and a driving device are arranged on the handle 20. The water tank 21 and the steam generator 11 are connected through a water pipe. The water tank 21 can store water. The water in the water tank 21 supplies water to the steam generator 11 under the action of the driving device. The steam generator 11 generates heat to turn the water entering the steam generator 11 into steam. The steam is ejected from the steam outlet 14 on the panel 12 to realize the steam ironing function. The lower end of the handle 20 is the water tank 21, which is detachably connected to the handle 20 through a thread.

[0025] The driving device can be a water pump or an energy storage mechanism in the water tank 21. The energy storage mechanism includes a spring and a piston. After water is added to the water tank 21, the spring is in a compressed state, and the elastic force of the spring pushes the piston to cause the water in the water tank 21 to flow toward the steam generating device 11.

[0026] The boiler 100 includes a tubular furnace body 110, and a furnace cavity 120 is formed in the furnace body 110. The boiler 100 has a water inlet and a steam outlet, and both the water inlet and the steam outlet are connected to the furnace cavity 120. The tubular furnace body 110 can be a circular, elliptical, polygonal structure, that is, the longitudinal section of the furnace body 110, the shape of the furnace cavity 120 is circular, elliptical or polygonal, etc., the furnace cavity 120 is surrounded by the furnace body 110, the panel 12 faces forward, and the tubular furnace body 110 can generate heat in all directions of up, down, left and right. The top wall of the furnace cavity 120 is also a heating structure integrally formed with the furnace body 110, which is a good conductor of heat. Even if the steam generating device 11 is deflected at a large angle or reversed during use, the water in the furnace cavity 120 can fully contact the furnace body 110, which is convenient for the boiler 100 to quickly heat the water, improve the flexibility of the use of the ironing device, and avoid the situation where the ironing device is tilted too much, resulting in the boiler 100 heating the water slowly and unevenly.

[0027] An inner frame 200 is provided in the oven cavity 120, and a flow channel is provided on the inner frame 200, and the flow channel makes the fluid in the oven cavity 120 flow in a curved manner. In this way, the fluid has a longer flow path in the oven cavity 120, so that the fluid can be heated and vaporized more fully, which is also conducive to the miniaturization design of the ironing device.

[0028] The inner frame 200 includes a shaft body 210, and a plurality of retaining ribs 220 are arranged on the side wall of the shaft body 210. The shape of the retaining ribs 220 matches the furnace cavity 120. The retaining ribs 220 have notches 221, and the notches 221 between adjacent retaining ribs 220 are staggered. There are spaced flow channels between adjacent retaining ribs 220, so that the fluid flows into the spaced flow channels through the notches 221 and then flows to the next staggered notch 221, thereby extending the flow path of the fluid. The retaining ribs 220 preferably abut against the inner wall of the furnace cavity 120 to prevent part of the fluid from flowing through the gap between the retaining ribs 220 and the cavity wall of the furnace cavity 120.

[0029] The gaps 221 between adjacent retaining ribs 220 are staggered by 180°, which can extend the flow path to the maximum extent. In other optional embodiments, the staggered angle can also be 60°, 90°, 135° or other angles.

[0030] In other embodiments, the retaining rib 220 may also be spiral to form a spiral flow channel.

[0031] The first heating element 230 is arranged on the inner frame 200, and the second heating element 130 is arranged on the boiler 100. Both the first heating element 230 and the second heating element 130 are heating tubes. In this way, the furnace cavity 120 can be heated more quickly and evenly, and the heating of the inner frame 200 does not depend on the second heating element 130, and the heating of the boiler 100 does not depend on the first heating element 230, thereby reducing the distance of heat conduction and improving the heating efficiency. In other optional embodiments, the first heating element 230 can be provided only on the inner frame 200, and the second heating element 130 is no longer provided on the boiler 100. In this way, there is no need to provide a heating element on the outer side of the furnace body 110, which can reduce the overall volume of the boiler 100, is beneficial to the spatial arrangement within the nozzle 10 and the miniaturized design of the ironing equipment, and fully utilizes the structure of the inner frame 200. At the same time, the material used for the inner frame 200 is reduced to reduce costs. At this time, the first heating element 230 is energized to generate heat which is first transferred to the inner frame 200, and then transferred from the inner frame 200 to the boiler 100, so that the inner frame 200 and the boiler 100 jointly heat the fluid in the furnace cavity 120.

[0032] The second heating element is fixed to the side of the furnace body 110, and the second heating element extends along the side of the furnace body 110 to form a "X" shape. The second heating element is a long strip heating tube, and the second heating element can contact the furnace body 110 more, so that the furnace body 110 can heat more quickly and evenly.

[0033] The panel 12 is fixed to the boiler 100 by screws, and the panel 12 abuts against the inner frame 200 to fix the inner frame 200, that is, the inner frame 200 abuts against the panel 12 on one hand and against the boiler 100 on the other hand, thereby achieving fixation.

[0034] The front end of the inner frame 200 is provided with a fixing part 240, and the boiler 100 and the panel 12 are fixed to clamp the fixing part 240. The extension part 250 and the panel 12 are against each other, and a folding edge 242 is provided on the fixing part 240, and a convex ring is provided on the panel 12, and the folding edge 242 and the convex ring are matched and connected.

[0035] like Figure 4-5 As shown, there is a surface cavity 13 between the fixing portion 240 and the panel 12, and a connecting hole 241 is provided on the fixing portion 240 to connect with the surface cavity 13. The inner frame 200 is provided with an extension portion 250, and the first heating element passes through the extension portion 250. The end of the first heating element is bent downward, and the wiring terminal of the first heating element extends from the extension portion 250 and is isolated from the surface cavity 13. In this way, the steam can be prevented from contacting the first heating element and from being corroded by the steam. The furnace body 110 in this embodiment is a tubular structure with an opening at the front and a closed rear end. In other optional embodiments, the furnace body 110 can also be a front-to-back through-structure. After the inner frame 200 is inserted into the furnace cavity 120, the opening at the rear end is blocked, and then the wiring terminal of the first heating tube passes through the rear end of the inner frame 200.

[0036] Under the action of the driving device, the water in the water tank 21 can enter the steam generating device 11 from the water inlet of the steam generating device 11 through the water pipe and flow into the furnace cavity 120. The first heating element and the second heating element are energized to generate heat, causing the inner frame 200 and the boiler 100 to heat up. The boiler 100 heats up, causing the water in the steam generating device 11 to gradually turn into steam and flow out from the steam outlet of the steam generating device 11, flow into the surface cavity 13 through the connecting hole 241 on the fixing part 240, and then be ejected from the steam outlet 14 on the panel 12 to realize the steam ironing function.
