Description
Technical Field
[0001] This utility model relates to an improvement of an electric iron component, particularly an improvement of the steam generating chamber. Background Technology
[0002] A steam iron is a common ironing tool that combines electricity and steam to effectively and conveniently handle various types of clothing wrinkles. It is widely used in both home and professional ironing settings. It primarily utilizes an electric current to generate heat through a heating element, converting water into steam. This steam is then sprayed onto the clothing through small holes in the soleplate, causing the fabric fibers to soften and expand due to the heat. The pressure and movement of the iron then easily smooth out wrinkles, restoring the garment to a smooth finish.
[0003] The steam generating chamber is the core component of the ironing soleplate. Common ironing soleplates have a steam generating chamber on top, which is equipped with flow channels and vaporization chambers. The bottom surface of the ironing soleplate has steam injection holes, and the steam generated is finally ejected from the steam injection holes to realize the steam ironing function.
[0004] The structural design of the steam generator directly affects the efficiency and quality of steam generation. However, existing steam generators suffer from low steam vaporization rates and low thermal energy utilization efficiency. Utility Model Content
[0005] In order to overcome the shortcomings of the low vaporization rate of steam generated in the steam generation chamber of current steam irons, this utility model provides a double-layer heating ironing soleplate.
[0006] The technical solution of this utility model to solve its technical problem is: a double-layer heated ironing soleplate, including a soleplate and a partition plate disposed on the soleplate. The soleplate is provided with a steam generating chamber, and the soleplate and the partition plate are provided with a chamber wall to surround the steam generating chamber. The partition plate separates the steam generating chamber into an upper chamber and a lower chamber. The upper chamber includes an upper inner labyrinth in the middle and an upper outer labyrinth on the periphery. The lower chamber includes a lower inner labyrinth in the middle and a lower outer labyrinth. A water inlet is provided at the starting point of the upper outer labyrinth. A first passage is provided at the end point of the upper outer labyrinth, and the first passage connects to the starting point of the lower outer labyrinth. A second passage is provided above the end point of the lower outer labyrinth, and the second passage connects to the starting point of the upper inner labyrinth. A third passage is provided at the end point of the upper inner labyrinth, and the third passage connects to the starting point of the lower inner labyrinth. The end point of the lower inner labyrinth connects to an exhaust chamber. Steam nozzles are provided at the bottom plate position of the exhaust chamber. The partition also includes an electric heating unit that supplies heat to the steam generation chamber.
[0007] Generally speaking, our base plate and partitions are made of thermally conductive metal.
[0008] A preferred location for the exhaust chamber is in the middle of the lower inner labyrinth.
[0009] The base plate structure is optimized, and the base plate is also provided with an outer edge, on which a connecting post is provided. The outer side of the partition is provided with a connecting ear, which is fixedly fitted onto the connecting post.
[0010] To prevent clothing from sticking together, a ring of perforations is provided around the outer edge.
[0011] To increase the heating contact area, the partition plate has raised textures that increase the contact area on the upper compartment.
[0012] In a preferred embodiment, the ridges are raised areas arranged in a grid pattern.
[0013] The structure of the electric heating unit is optimized, wherein the electric heating unit is an electric heating tube, and the two ports of the electric heating tube are opened at the upper end of the partition.
[0014] For ease of arrangement, an electrical compartment is also enclosed at the upper end of the partition, and the two ports of the electric heating tube are located inside the electrical compartment.
[0015] To improve the steam vaporization effect of the upper outer labyrinth, a low-lying section with a sunken bottom is also provided on the upper outer labyrinth.
[0016] To improve the purity of the steam in the flow, steps are provided at the connection between the upper inner labyrinth and the second outlet, and between the upper inner labyrinth and the third outlet. The step at the second outlet is used to raise the height to prevent liquid from splashing into the upper inner labyrinth, and the step at the third outlet is used to prevent residual liquid from the third section from dripping into the lower inner labyrinth.
[0017] In use, this invention differs from existing methods. Water first enters the upper outer labyrinth through the inlet, undergoes initial heating and vaporization, and then enters the lower outer labyrinth through the first outlet. In the lower outer labyrinth, it undergoes a second stage of heating and vaporization. Then, the hot steam rises from the second outlet into the upper inner labyrinth, undergoes a third stage of heating and vaporization, and then descends from the third outlet into the lower inner labyrinth, undergoing a fourth stage of heating and vaporization. Finally, the steam enters the exhaust chamber and is ejected from the steam nozzle, completing one vaporization cycle.
[0018] In our four-stage heating process, the first and second stages of heating and vaporization can be regarded as ordinary vaporization stages, in which some liquid still exists. However, when entering the third and fourth stages of heating and vaporization, especially when entering the third stage from the second passage through the second passage in the second stage, vapor-liquid separation occurs due to gravity. Only steam can pass through the second passage into the upper inner labyrinth to receive further heating and vaporization. The third and fourth stages of heating and vaporization are regarded as deep vaporization stages, in which the flowing medium is steam.
[0019] The beneficial effects of this invention are as follows: 1. The double-layer vaporization design enables the steam generation chamber to produce steam more efficiently. In the ordinary vaporization stage, water is initially heated to prepare for the deep vaporization stage. Especially during the process of the lower chamber entering the upper chamber, the steam purity is screened and purified, reducing the time from room temperature to the generation of high-temperature steam, thus shortening the preheating time of the iron and allowing users to start ironing more quickly. 2. Because the generation process of high-temperature, high-purity steam is more stable and efficient, the pressure and wear on key components such as heating elements and water pumps in the steam generation chamber are relatively less. Stable operation helps reduce component damage and aging, lowering maintenance costs. 3. The ordinary vaporization stage is achieved in the upper and lower outer labyrinths, while the deep vaporization stage is achieved in the upper and lower inner labyrinths. Given that the temperature on the outside of the iron is lower than the temperature in the middle, this design is thermally efficient and improves energy utilization. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] Example 1 Combined with appendix Figures 1 to 5A double-layer heated ironing soleplate includes a soleplate 1 and a partition 2 disposed on the soleplate 1. A steam generating chamber 3 is provided on the soleplate 1. A bulkhead 27 is provided on the soleplate 1 and the partition 2 to enclose the steam generating chamber 3. The partition 2 divides the steam generating chamber 3 into an upper chamber and a lower chamber. The upper chamber includes a central upper inner maze 4 and an outer upper outer maze 5. The lower chamber includes a central lower inner maze 6 and a lower outer maze 7. A water inlet 8 is provided at the starting point of the upper outer maze 5. The upper outer maze 5 has a first passage 9 at its end point, which connects to the starting point of the lower outer maze 7. The lower outer maze 7 has a second passage 10 above its end point, which connects to the starting point of the upper inner maze 4. The upper inner maze 4 has a third passage 11 at its end point, which connects to the starting point of the lower inner maze 6. The lower inner maze 6 connects to the exhaust chamber 12. The exhaust chamber 12 has a steam nozzle 13 at the bottom plate 1 on its bottom surface. The partition 2 also includes an electric heating unit 14 for heating the steam generating chamber 3.
[0027] Our base plate 1 and partition plate 2 are both made of thermally conductive metal, preferably stainless steel or aluminum alloy.
[0028] A preferred location for the exhaust chamber 12 is in the middle of the lower inner labyrinth 6.
[0029] The starting and ending points of the upper outer maze 5 are separated by a partition 15.
[0030] The structure of the base plate 1 is optimized. The base plate 1 is also provided with an outer edge 16, and a connecting post 17 is provided on the outer edge 16. The outer side of the partition 2 is provided with a connecting ear 18, and the connecting ear 18 is fixedly fitted on the connecting post 17. We adopt the form of a threaded part.
[0031] To prevent clothing from sticking together, a ring of perforations 19 is provided on the outer edge 16.
[0032] To increase the heating contact area, the partition 2 is provided with raised textures 20 that increase the contact area on the upper compartment.
[0033] In a preferred embodiment, the ridges 20 are raised areas arranged in a grid pattern.
[0034] The structure of the heating unit 14 is optimized. The heating unit 14 is an electric heating tube, and the two ports 21 of the electric heating tube are opened at the upper end of the partition 2.
[0035] For ease of arrangement, an electrical compartment 22 is also enclosed at the upper end of the partition 2, and the two ports 21 of the electric heating tube are opened in the electrical compartment 22.
[0036] In order to improve the steam vaporization effect of the upper outer labyrinth 5, a low-lying section 23 with a sunken bottom surface is also provided on the upper outer labyrinth 5.
[0037] To improve the purity of the steam in the flow, steps 24 are provided at the connection between the upper inner labyrinth 4 and the second passage 10, and between the upper inner labyrinth 4 and the third passage 11. The step at the second passage 10 is used to raise the height to prevent liquid from splashing into the upper inner labyrinth 4, and the step at the third passage 11 is used to prevent residual liquid from the third section from dripping into the lower inner labyrinth 6.
[0038] In this embodiment, water first enters the upper outer labyrinth 5 through the inlet 8, undergoes a first stage of heating and vaporization, and then enters the lower outer labyrinth 7 through the first outlet 9. The water then undergoes a second stage of heating and vaporization in the lower outer labyrinth 7. The hot steam then enters the upper inner labyrinth 4 through the second outlet 10, undergoes a third stage of heating and vaporization in the upper inner labyrinth 4, and then enters the lower inner labyrinth 6 through the third outlet 11, undergoes a fourth stage of heating and vaporization in the lower inner labyrinth 6. Finally, the steam enters the exhaust chamber and is ejected from the steam nozzle, completing one vaporization cycle.
[0039] Combined with appendix Figure 5 In our four-stage heating process, the first and second stages of heating and vaporization can be considered as ordinary vaporization stage 25, in which some liquid still exists. However, when entering the third and fourth stages of heating and vaporization, especially when entering the third stage from the second passage 10, vapor-liquid separation occurs due to gravity. Only steam can pass through the second passage 10 into the upper inner labyrinth 4 for further heating and vaporization. The third and fourth stages of heating and vaporization are considered as deep vaporization stage 26, in which the flowing medium is steam. Figure 5 We use the imaginary part to represent the flow direction arrow in the intermediate-deep vaporization stage 26, and we use the real part to represent the flow direction arrow in the ordinary vaporization stage 25.
[0040] The beneficial effects of this embodiment are as follows: 1. The dual-layer vaporization design enables the steam generation chamber to produce steam more efficiently. In the ordinary vaporization stage, water is initially heated to prepare for the deep vaporization stage. Especially during the process of the lower chamber entering the upper chamber, the steam purity is screened and purified, reducing the time from room temperature to the generation of high-temperature steam, thereby shortening the preheating time of the iron and allowing users to start ironing more quickly. 2. Because the generation process of high-temperature, high-purity steam is more stable and efficient, the pressure and wear on key components such as heating elements and water pumps in the steam generation chamber are relatively less. Stable operation helps reduce component damage and aging, lowering maintenance costs. 3. The ordinary vaporization stage is achieved in the upper and lower outer labyrinths, while the deep vaporization stage is achieved in the upper and lower inner labyrinths. Given that the temperature on the outside of the iron is lower than the temperature in the middle, this design is thermally efficient and improves energy utilization.
