Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and more specifically, to a novel electric steam boiler for garment pressing. Background Art

[0002] Garment factories produce a large number of garments every day. During the production process, an electric boiler is required to generate high-temperature steam for pressing the garments. Since relatively dry steam is needed for garment pressing, when the water and steam mixture after heating by a traditional electric boiler enters the iron, tail gas needs to be discharged to separate the water, which will consume a large part of the steam and waste about 30% of the electric energy, increasing the use cost. Moreover, the water supplied to the electric boiler is ordinary tap water. Due to the relatively high hardness of ordinary municipal tap water and many impurities in the water, such as heavy metals, colloidal carbonates, magnesium ions, etc., when the tap water containing these impurities is heated in the boiler body, heavy-polluting substances (scale) are decomposed at high temperatures and accumulate more and more over time. It is very easy to damage the internal components of the boiler and pollute the environment, and it will also reduce the service life of the electric boiler, increase energy consumption, and have low efficiency.

Detailed implementation manners

[0029] The following further elaborates on the present invention in detail in conjunction with the drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0030] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0031] Such as Figures 1 - 8As shown in the figure, the present invention provides a new type of electric steam boiler for garment pressing and ironing, comprising: a housing 1, a steam generating device 2, a water pump 3, a water purification device 4, a water tank 5, and an iron 6. The water tank 5 is arranged inside the housing 1. The water purification device 4 is connected between the water tank 5 and the water pump 3 through a water pipe 7. The water pump 3 is also connected to the steam generating device 2 through the water pipe 7. The upper end of the steam generating device 2 extends out of the housing 1 and is provided with a steam outlet valve 8. The steam outlet valve 8 is connected to the iron 6 through a steam pipe 9.

[0032] The working principle of the above technical solution: The water tank 5 is arranged inside the housing 1. The upper end of the water tank 5 is connected with a water inlet pipe 7, and the water inlet of the water inlet pipe 7 is arranged outside the housing 1. Water can be manually injected into the water tank 5, or the water inlet can be directly connected to the tap water pipe for water injection. The bottom end of the water tank 5 is connected to the bottom end of the water purification device 4 through a water pipe 7, and the bottom end of the water purification device 4 is connected to the water pump 3 through a water pipe 7. When the electric steam boiler works, the water pump 3 starts to pump the water in the water tank 5 into the steam generating device 2. The tap water first passes through the water purification device 4 through the water pipe 7 to filter out the impurities in the water, and then enters the steam generating device 2 through the water pipe 7 and the water pump 3. When the water level in the steam generating device 2 reaches a certain height, heating starts to generate water steam. The internal structure of the steam generating device 2 can filter out the moisture contained in the water steam to a certain extent. The water steam enters the iron 6 through the steam outlet valve 8 at the upper end of the steam generating device 2 and the steam pipe 9 connected thereto. The relatively dry water steam coming out of the iron 6 can be used for garment pressing and ironing.

[0033] The beneficial effects of the above technical solution: Through the design of the above structure, the water purification device 4 can filter out the impurities in the tap water before the tap water enters the steam generating device 2 for heating, reducing the scale generated after heating the tap water, being very clean and environmentally friendly, effectively improving the work efficiency, reducing energy consumption, and increasing the service life of the boiler. The steam generating device 2 can filter out the water in the generated water steam to a certain extent, making the water steam coming out of the iron 6 relatively dry and having a better effect on garment pressing and ironing.

[0034] In one embodiment, the steam generating device 2 includes a first furnace liner 2-1 and a second furnace liner 2-2. The lower left end of the first furnace liner 2-1, the lower end of the second furnace liner 2-2, and the water pump 3 are communicated through the water pipe 7. A first one-way valve a is arranged on the water pipe 7 close to the water pump 3, a second one-way valve b is arranged on the water pipe 7 close to the lower left end of the first furnace liner 2-1, and a third one-way valve c is arranged on the water pipe 7 close to the lower end of the second furnace liner 2-2. The upper ends of the first furnace liner 2-1 and the second furnace liner 2-2 are communicated through the steam pipe 9, and a fourth one-way valve d is arranged on the steam pipe 9.

[0035] Working principle of the above technical solution: The steam generating device 2 is provided with two furnace linings. The first furnace lining 2-1 is mainly used for heating water to produce water vapor and can filter out part of the water in the water vapor. The second furnace lining 2-2 is mainly used for storing steam and filtering out the water in the water vapor. The left side of the lower end of the first furnace lining 2-1, the lower end of the second furnace lining 2-2, and the water pump 3 are connected through a water pipe 7. The upper ends of the first furnace lining 2-1 and the second furnace lining 2-2 are connected through a steam pipe 9. When the internal pressures of the first furnace lining 2-1 and the second furnace lining 2-2 are equal, the steam and water between the two furnace linings will not flow into each other. When the pressure in the first furnace lining 2-1 is greater than that in the second furnace lining 2-2, the fourth one-way valve d opens, and the water vapor flows from the first furnace lining 2-1 to the second furnace lining 2-2. The water separated from the first furnace lining 2-1 flows back to its bottom, and the water separated from the second furnace lining 2-2 accumulates at its bottom. When the water pump 3 supplies water to the first furnace lining 2-1 under high temperature and high pressure, the first one-way valve a and the second one-way valve b open, and the water flows from the water tank 5 to the first furnace lining 2-1. The temperature inside the first furnace lining 2-1 decreases, and its internal pressure also decreases. At this time, the pressure in the second furnace lining 2-2 will be greater than the pressure in the first furnace lining 2-1, and the second one-way valve b and the third one-way valve c will open simultaneously. The water accumulated at the bottom of the second furnace lining 2-2 will flow through the water pipe 7 into the first furnace lining 2-1, realizing the recycling of water.

[0036] Beneficial effects of the above technical solution: Through the design of the above structure, the steam generating device 2 is provided with two furnace linings. The two furnace linings can simultaneously produce water vapor and filter out the water in the water vapor. Sensors are installed in the second one-way valve b, the third one-way valve c, and the fourth one-way valve d, which can control the opening or closing of the one-way valves according to the pressure magnitudes in the two furnace linings. Moreover, the filtered water can be recycled. The separation of water and vapor makes the water vapor coming out of the iron 6 drier, which is more convenient for ironing clothes. The water filtered by the two furnace linings can be reused to be heated again, improving the utilization rate and efficiency, saving electric energy, and being very environmentally friendly.

[0037] In one embodiment, a heating device 10 is provided at the inner bottom end of the first furnace lining 2-1, and a first separator 11 is provided at the top end. A second separator 12 is provided inside the second furnace lining 2-2.

[0038] Working principle of the above technical solution: A heating device 10 is provided at the bottom end of the first furnace lining 2-1, which is used to heat water into water vapor. The water vapor flows upward through the first separator 11 at the top end of the first furnace lining 2-1. The first separator 11 can filter out part of the water in the water vapor. The filtered water vapor continues to flow into the second furnace lining 2-2, and the water and vapor are separated through the second separator 12. Finally, relatively dry water vapor for ironing clothes can be obtained.

[0039] Advantages of the above technical solution: Through the design of the above structure, it is avoided that a large part of steam needs to be consumed to separate water by discharging tail gas when the steam that has not undergone water vapor separation enters the iron 6. The double-chamber design and the provided separator can effectively obtain dry water vapor, saving electric energy and water, avoiding unnecessary waste, and being very energy-saving and environmentally friendly.

[0040] In one embodiment, the first separator 11 includes a water filter 11-1 and a water receiver 11-2. The upper end of the water filter 11-1 is connected to the top end of the first furnace chamber 2-1, and the lower end is connected to a first connecting pipe 11-3 coaxial with it. A second connecting pipe 11-4 is sleeved outside the first connecting pipe 11-3. The inner wall of the second connecting pipe 11-4 is connected to a disc 11-5 provided at the lower end of the first connecting pipe 11-3. The upper end of the second connecting pipe 11-4 is connected to the water receiver 11-2 coaxial with it. The water receiver 11-2 is sleeved outside the water filter 11-1; a plurality of first round holes 11-1-1 are provided on the bottom surface of the water filter 11-1, a plurality of second round holes 11-5-1 are provided on the disc 11-5, and a retaining ring 11-2-1 extending obliquely upward is provided around the upper end of the water receiver 11-2.

[0041] Working principle of the above technical solution: An air outlet is provided at the top of the first furnace liner 2-1. The upper end of the water filter 11-1 is hermetically connected to the top of the first furnace liner 2-1, sealing the air outlet of the first furnace liner 2-1 inside the water filter 11-1. The water receiver 11-2 is sleeved outside the water filter 11-1, with a certain gap left between them. The second connecting pipe 11-4 at the lower end of the water receiver 11-2 can be inserted into the water stored at the bottom of the first furnace liner 2-1. The gap between the retaining ring 11-2-1 provided at the upper end of the water receiver 11-2 and the top of the first furnace liner 2-1 is relatively small. When the heating device 10 heats up, a part of the water at the bottom of the first furnace liner 2-1 is heated to become water vapor and flows upward. It enters the gap between the water filter 11-1 and the water receiver 11-2 from the gap between the retaining ring 11-2-1 and the top of the first furnace liner 2-1. At this time, a large amount of water vapor is squeezed by the gap, accelerating the flow rate of the air current. The air current first hits the outer wall of the water filter 11-1 and then rebounds to the inner wall of the water receiver 11-2. Due to the relatively fast flow rate of the air current, the water vapor generates centrifugal force when swirling between the water filter 11-1 and the water receiver 11-2. The water is affected by gravity and will not continue to flow with the water vapor. It will adhere to the outer wall of the water filter 11-1 and the inner wall of the water receiver 11-2. The water vapor will continue to rise through the multiple first round holes 11-1-1 at the lower end of the water filter 11-1 and enter the second furnace liner 2-2 through the air outlet at the upper end of the first furnace liner 2-1. The water adhering to the outer wall of the water filter 11-1 and the inner wall of the water receiver 11-2 will flow downward. When the water accumulated at the bottom of the water receiver 11-2 is sufficient, the water will continue to flow downward along the gap between the first connecting pipe 11-3 and the second connecting pipe 11-4, and flow to the bottom of the first furnace liner 2-1 through the second round hole 11-5-1 on the disc 11-5, and the water is recycled again.

[0042] Beneficial effects of the above technical solution: Through the design of the above structure, preliminary water-vapor separation can be achieved inside the first furnace liner 2-1, and the separated water is recycled. On the first separator 11, the gap between the retaining ring 11-2-1 and the top of the first furnace liner 2-1 makes the passing water vapor faster, generating centrifugal force between the water filter 11-1 and the water receiver 11-2, separating a part of the water, and making the water vapor entering the second furnace liner 2-2 drier.

[0043] In one embodiment, the second separator 12 includes a plurality of first horizontal plates 12-1, a plurality of second horizontal plates 12-2, a plurality of first vertical plates 12-3, and a plurality of second vertical plates 12-4. A partition plate 12-5 extends vertically downward from the top end of the second furnace liner 2-2. An air outlet and an air inlet are provided at the upper end of the second furnace liner 2-2. The air inlet is located on the right side of the partition plate 12-5, and the air outlet is located on the left side of the partition plate 12-5. The plurality of first horizontal plates 12-1 and the plurality of second horizontal plates 12-2 are arranged at intervals in the vertical direction between the left side wall of the second furnace liner 2-2 and the partition plate 12-5. The left end of the first horizontal plate 12-1 is connected to the left side wall of the second furnace liner 2-2 and the right end is inclined upward. The right end of the second horizontal plate 12-2 is connected to the partition plate 12-5 and the left end is inclined upward. The first vertical plate 12-3 is arranged perpendicular to the horizontal plane and its lower end is connected to the upper surface of the first horizontal plate 12-1. The second vertical plate 12-4 is arranged perpendicular to the horizontal plane and its upper end is connected to the lower surface of the second horizontal plate 12-2. The plurality of first vertical plates 12-3 and the plurality of second vertical plates 12-4 are distributed at intervals in the horizontal direction. A third round hole 12-1-1 is provided at the left end of the first horizontal plate 12-1, a fourth round hole 12-2-1 is provided at the right end of the second horizontal plate 12-2, and a fifth round hole 12-3-1 is provided at the lower end of the first vertical plate 12-3.

[0044] Working principle of the above technical solution: When water vapor enters through the air inlet of the second furnace liner 2-2, it first flows downward through the space formed by the partition plate 12-5 and the right side wall of the second furnace liner 2-2. There is a space between the lower end of the partition plate 12-5 and the bottom of the second furnace liner 2-2, and the water vapor will continue to flow leftward into the space formed by the partition plate 12-5 and the left side wall of the second furnace liner 2-2. Since there are only certain gaps between the right end of the first cross plate 12-1 and the partition plate 12-5, and between the left end of the second cross plate 12-2 and the left side wall of the second furnace liner 2-2 for the water vapor to pass through, the water vapor flowing leftward will continue to flow upward. First, it will be blocked by the first cross plate 12-1. Part of the water will contact the first cross plate 12-1 and adhere to it. The water vapor can only pass through the gap between the right end of the first cross plate 12-1 and the inner wall of the second furnace liner 2-2. At this time, due to the squeezing of the gap, the air flow velocity of the water vapor is relatively large. The air flow passing through the gap at the right end of the first cross plate 12-1 will hit the lower surface of the second cross plate 12-2 or the right side surface of the second vertical plate 12-4, and after rebounding, it will form an air flow swirl on the upper surface of the first cross plate 12-1. The water vapor generates centrifugal force, and the water will not continue to flow with the water vapor due to gravity and will adhere to the cross plate or vertical plate. At this time, the water vapor continues to flow leftward through the gap between the lower end of the second vertical plate 12-4 and the first cross plate 12-1, and an air flow swirl is formed between the first vertical plate 12-3, the second vertical plate 12-4, the first cross plate 12-1, and the second cross plate 12-2, generating centrifugal force, which can separate part of the water. According to this principle, the water vapor passes through layers of cross plates and vertical plates to separate the water and vapor, and finally reaches the air outlet at the upper end of the second furnace liner 2-2; the water left on the cross plates and vertical plates can flow downward through the third round hole 12-1-1, the fourth round hole 12-2-1, and the fifth round hole 12-3-1 and accumulate at the bottom of the second furnace liner 2-2. When the pressure in the second furnace liner 2-2 is greater than the pressure in the first furnace liner 2-1, the second one-way valve b and the third one-way valve c will open simultaneously, and the water accumulated at the bottom of the second furnace liner 2-2 will flow through the water pipe 7 into the first furnace liner 2-1 and can be recycled.

[0045] Beneficial effects of the above technical solution: The second separator 12 blocks the water vapor layer by layer through multiple cross plates and vertical plates, effectively separating the water and vapor. Moreover, the water separated in the second furnace liner 2-2 can flow back into the first furnace liner 2-1 for repeated recycling. The water vapor can become drier after passing through the first separator 11 and the second separator 12, and is more suitable for ironing clothes. The number of cross plates and vertical plates can be increased or decreased according to the actual usage amount of water vapor.

[0046] In one embodiment, a rotary separator 13 is provided at the air outlet of the second furnace liner 2-2.

[0047] Working principle of the above technical solution: The rotary separator 13 is similar to the blades of a fan and can also separate water and steam to a certain extent. A separately controlled motor is connected to the rotary separator 13. If the water vapor coming out of the iron 6 does not meet the usage standard, the rotary separator 13 can be turned on to separate a part of the water for optional use.

[0048] Beneficial effects of the above technical solution: The rotary separator 13 can be selectively used to achieve the effect of the third separation of water and steam.

[0049] In one embodiment, the water purification device 4 includes a filter cotton filter element 4-1 and a filter membrane filter element 4-2. The filter cotton filter element 4-1 is arranged at the water inlet of the water purification device 4, and the filter membrane filter element 4-2 is arranged at the water outlet of the water purification device 4. The two are connected by the water pipe 7.

[0050] Working principle of the above technical solution: The filter cotton is made of PP cotton. When the tap water in the water tank 5 enters the interior of the water purification device 4, it first passes through the filter cotton filter element 4-1. The PP cotton can filter out colloidal impurities, micro mud, rust, insect eggs, organic pollution mineral debris, etc. with a diameter greater than 5 microns in the tap water, and then enters the filter membrane filter element 4-2 through the water pipe 7. The filter membrane can adopt a reverse osmosis membrane, which is an artificial semi-permeable membrane with certain characteristics made by simulating biological semi-permeable membranes. The membrane pore diameter of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matters, etc. in the water, making the filtered water no longer produce scale after heating.

[0051] Beneficial effects of the above technical solution: The filter cotton and the filter membrane can effectively separate water and impurities in the water, making the heated water not produce scale, prolonging the service life of the furnace lining. The filter cotton can be replaced in time according to the usage situation. The filter membrane filter element 4-2 can be taken out and cleaned and then used again. The reverse osmosis membrane is widely used in fields such as electric power, petrochemical industry, steel, electronics, medicine, food and beverage, municipal administration and environmental protection. It plays an important role in seawater and brackish water desalination, boiler feed water, industrial pure water and electronic grade ultrapure water preparation, drinking pure water production, wastewater treatment and special separation processes. The water filtered by the water purification device 4 is very clean and environmentally friendly, improving the working efficiency of the boiler and reducing energy consumption.

[0052] In one embodiment, the heating device 10 uses a quartz carbon fiber heating tube.

[0053] Working principle of the above technical solution: In the quartz carbon fiber heating tube, carbon fiber filaments are wound and formed, cured, and then sealed in a quartz tube. Carbon fiber is a high-strength and high-modulus fiber obtained by removing other elements except carbon from polyacrylonitrile fiber, viscose fiber, or pitch fiber through high-temperature vacuum heating. It has high chemical stability and high-temperature resistance. Among them, viscose-based carbon fiber produced from wood pulp and cotton pulp has conductivity and soft processability, so it is often used to manufacture various heating elements.

[0054] Beneficial effects of the above technical solution: The carbon fiber heating wire has the advantages of high electro-thermal conversion efficiency, rapid heating, high heat radiation, obvious energy-saving effect, safety, green environmental protection, etc. The carbon fiber heating wire is sealed with a quartz tube outside, which has good corrosion resistance and a long service life.

[0055] In one embodiment, the first furnace liner 2-1 and the second furnace liner 2-2 are both made of 304 stainless steel.

[0056] Working principle of the above technical solution: 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance.

[0057] Beneficial effects of the above technical solution: In the first furnace liner 2-1 and the second furnace liner 2-2, water needs to be heated for a long time to generate water vapor, and the water will more or less corrode the inside of the furnace liner. Using 304 stainless steel is not easy to rust, has good corrosion resistance, and is cheap.

[0058] In one embodiment, it further includes a microcomputer control module board. The microcomputer control module board is arranged on the housing 1. The microcomputer control module board is provided with a voltage regulator that can control the working power of the heating device 10. The voltage regulator includes an exciting coil W and a switching tube Q. The power of the heating device 10 can be calculated by the following formula:

[0059]

[0060] Where I av is the average value of the current of the exciting coil W, T is the pulse period of the switching tube Q, t1 is the conduction time of the switching tube Q, i on is the current of the exciting coil W when the switching tube is conducting, i off is the current of the exciting coil W when the switching tube Q is cut off, R is the equivalent resistance on the loop composed of the voltage regulator and the heating device 10, δ is the conduction ratio of the switching tube Q (t1 / T), P is the working power of the heating device 10, R0 is the resistance value of the heating device 10, and U is the terminal voltage of the heating device 10.

[0061] Working principle of the above technical solution: The microcomputer control module board is equipped with a voltage regulator for adjusting the working power of the heating device 10. It can control and adjust the power consumption of the heating device 10 according to the steam consumption. The voltage regulator includes an excitation coil W and a switching transistor Q. By controlling the on-off time of the switching transistor Q, the current of the excitation coil W is adjusted, and then the terminal voltage of the heating device 10 is adjusted within a certain range to change the power of the heating device 10. Denote i on is the integrand and the integration interval is [0, t1], Denote i off is the integrand and the integration interval is [t1, T]. As long as the conduction ratio of the switching transistor Q is adjusted according to the working state change of the heating device 10, the current of the excitation coil W can be controlled. Due to the inductance of the excitation coil W, under the control of the switching transistor Q, the current of the excitation coil W changes according to the exponential law. When the switching transistor Q is on, the current of the excitation coil W increases exponentially. When the switching transistor Q is off, the induced electromotive force on the excitation coil discharges through the freewheeling diode D, and the excitation current decays according to the exponential law, so that the terminal voltage of the heating device 10 can be adjusted within a certain range. The power consumption of the heating device 10 is directly proportional to the terminal voltage. When the required steam volume is small, the conduction ratio can be adjusted by the switching state of the switching transistor Q in the voltage regulator in the microcomputer control module board, the current of the excitation coil W is adjusted to decrease, the terminal voltage decreases, and then the power of the heating device 10 decreases, reducing the steam output.

[0062] Beneficial effects of the above technical solution: The voltage regulator in the microcomputer control module board can accurately calculate the power consumption of the heating device 10, and then configure according to the steam volume and power consumption discharged by the iron 6. It can realize the accurate control of the power consumption of the heating device 10 through the microcomputer control module board, avoid wasting electric energy due to the inability to adjust the steam volume output, save energy and cost, and avoid waste.
