Description

Technical Field

[0001] The invention relates to a method for improving indoor heating, which is composed of a circular heating electric furnace wire electric furnace and a stepless temperature and voltage regulator, a circular electric ceramic furnace microcrystalline panel, an upper stainless steel barrel, a lower stainless steel barrel and water, which are used in conjunction with each other, and the method heats the water added to the lower stainless steel barrel to boil, and efficiently utilizes the water vapor generated by the heating to achieve low-cost and noise-free indoor heating. Background Art

[0002] In the 19th century, central heating with boilers as heat sources and steam or hot water as heat media appeared in Europe. The first person to install heating in his home and weld copper plates on high-temperature pipes to make radiators was James Watt, who invented the steam engine and was one of the pioneers of heating. Since then, steam heating and hot water heating have become the two main forms of indoor heating, and have continued to this day. Russian Franz Sangali invented the cast iron radiator between 1855 and 1857, which was widely used.

[0003] Central heating requires a large one-time investment and high operating and maintenance costs, because the distance of the heat source pipeline, the different floor structures and weather changes will cause obvious differences in indoor temperature; even if aluminum or copper radiators are used, they cannot reach a satisfactory temperature when the heating source temperature is low. The key is that the heating time and temperature cannot be controlled by oneself, that is, it is impossible to make personalized choices. Taking the four-month heating period of a small unit with a heating billing area of ​​48 square meters as an example, the annual heating fee reaches 1,200 yuan, and the heating fee will continue to increase as the room area increases. Even in southern China, the winter will be close to zero degrees; therefore, indoor heating in winter is necessary for most areas in China, and the elderly and the weak need warmth in winter even more.

[0004] In addition to central heating, there are also heating methods such as air conditioning, electric heaters, and small solar heating. Taking the widely used air conditioning heating as an example, if a 1.5-horsepower air conditioner is used for heating in a room, and the heating temperature is set to 22-24°C in the cold winter, the hourly heating power consumption is much greater than the cooling power consumption, reaching about 2 degrees per hour; long-term use of air conditioning for heating will reduce the service life of the air conditioner. In addition, if the air conditioner is operated in a closed room for a long time and is not cleaned and maintained for a long time, it will also have a certain impact on the air quality; and because the indoor temperature is low, the doors and windows are closed in winter, and the indoor air cannot be circulated and updated for a long time, which will affect the indoor air quality. Under the ideal temperature conditions, the costs of other heating methods are also higher than the cost of central heating.

[0005] International Electrotechnical Commission standard: IEC60335-2-30 is one of the international safety standards for household electric heating appliances. In this standard, there are corresponding requirements for the surface temperature rise of heaters. For example, for the heated surface that is touched, its surface temperature rise should not exceed a specific temperature, such as 55°C. The surface temperature of radiators for centralized heating in China is around 40°C. According to relevant regulations, the indoor temperature is qualified if it reaches above 18°C. In fact, the comfortable indoor temperature for humans in winter is around 22-24°C. Summary of the invention

[0006] The purpose of the present invention is to achieve a comfortable and ideal temperature and ensure the quality requirements of indoor air in a simple way and realize a low-cost, noise-free and environmentally friendly indoor heating method.

The circular electric ceramic stove microcrystalline panel (3) is in direct contact with the top of the refractory electric stove plate (8) of the circular heating electric stove (1), and the bottom of the lower stainless steel barrel (4) is in direct contact with the circular electric ceramic stove microcrystalline panel (3) covered on the circular heating electric stove (1). The distance between the bottom of the lower stainless steel barrel (4) and the top of the heating electric stove wire (9) of the circular heating electric stove (1) can be shortened to improve the heating efficiency. The outer diameter of the bottom of the lower stainless steel barrel (4) is the same as the outer diameter of the circular electric ceramic stove microcrystalline panel (3) covered on the circular heating electric furnace wire electric furnace (1), which is conducive to improving the heating effect; three fixing nuts (6) with through holes facing downwards are welded at equal distances at the outer diameter of the lower end of the lower stainless steel barrel (4), the upper end external threads of the three prepared support rods (7) are matched and connected with the internal threads of the three fixing nuts (6) with through holes facing downwards, and the lower end bottoms of the three support rods (7) connected with the internal threads of the three fixing nuts (6) with through holes facing downwards are in contact with the floor, and the three support rods (7) can be rotated and adjusted to stabilize the lower stainless steel barrel (4) and reduce the pressure on the circular heating electric furnace wire electric furnace (1);Three fixed guide plates (73) are respectively arranged between the three prepared support rods (7) and the three support legs (68) of the circular heating electric furnace wire furnace (1), and the three fixed guide plates (73) are respectively fixedly connected to the three support legs (68) of the circular heating electric furnace wire furnace (1); the three support rods (7) of the lower stainless steel barrel (4) are positioned and lowered through the three fixed guide plates (73); limiting the weight of water added to the barrel body of the lower stainless steel barrel (4) is one of the necessary conditions for achieving the ideal effect of low-power and low-cost heating. After repeated experiments, it is found that when the height of water added to the barrel body of the lower stainless steel barrel (4) is 3 to 8 cm, the ideal effect of low-power and low-cost heating can be achieved; Water is poured into the barrel (4), the open end of the upper stainless steel barrel (5) is inserted downward into the inner side of the open end of the lower stainless steel barrel (4), and the open ends of the two stainless steel barrels are sealed and connected together to form a closed space; the power is turned on to turn on the circular heating electric furnace (1) to heat the water added to the lower stainless steel barrel (4), and the water vapor generated after the water is heated and boiled heats the upper stainless steel barrel (5) and the lower stainless steel barrel (4), and the condensed water formed after the rising water vapor cools down falls back into the lower stainless steel barrel (4), and the water vapor generated after being heated continuously moves upward, and the cycle repeats; after the water is heated and boiled, the circular heating electric furnace (1) is adjusted to lower the temperature of the circular heating electric furnace (2). 1) power, completes the conversion and transmission of heat energy without leaking water vapor, and achieves a good heating effect; the height and diameter of the assembly formed by connecting two stainless steel drums with openings facing each other are effectively increased, and the volume of the enclosed space can be increased. When the high-temperature water vapor is not leaked, its capacity is increased, and when the heating power of the circular heating electric furnace (1) is increased, the storage space for the water vapor generated by upward movement is increased.

The water injected into the lower stainless steel barrel (4) is in a low-power heating state and continuously boils slightly, which can reduce the noise to less than 20dB; when the circular heating electric furnace wire furnace (1) is selected to adopt a 200W-300W low-power constant temperature stage for continuous heating for 24 hours, during which the electric meter shows that the electricity consumption is 0.10 yuan to 0.15 yuan per hour, the top surface temperature of the upper stainless steel barrel (5) can still stably reach 45°C to 55°C, and no sound can be heard at a distance of 30cm from the sound source;When the indoor area is 15 to 18 square meters, when the sum of the outer surface areas of the upper stainless steel barrel (5) and the lower stainless steel barrel (4) reaches 7000 to 15000 square centimeters, the temperature of the top surface of the upper stainless steel barrel (5) and the outer surface of the lower stainless steel barrel (4) are higher than the outer surface temperature of the traditional centralized heating indoor radiator, so the indoor heating needs in winter can be fully met; too much weight of water injected into the lower stainless steel barrel (4) will reduce the boiling state of water and reduce the heating effect; during the continuous heating process, the weight of water reduced by 1 to 25 grams per hour during the process of evaporation of the water injected into the lower stainless steel barrel (4) into water vapor, and the same amount of water is regularly supplemented according to the amount of water reduced every day to ensure that the water injected into the lower stainless steel barrel (4) produces a better water vapor heating effect when boiling; the water stains on the bottom of the lower stainless steel barrel (4) are regularly cleaned and wiped to maintain the heat conduction effect of the lower stainless steel barrel (4).

The distance between the bottom of the black crystal panel of the ceramic stove can improve the heating effect, the components of the electric control system and the temperature control system of the round electric ceramic stove and the cooling exhaust fan are eliminated, and only the heating plate composed of the iron-chromium heating plate and the heat-resistant plate and the stepless temperature and voltage regulator are retained to adjust the power size, so that the improved round electric ceramic stove can work continuously in a low-power state and eliminate the noise generated during work. The improved round electric ceramic stove has improved the heating effect; using the improved round electric ceramic stove to boil water or heat food can eliminate the influence of radiation when the induction cooker is working, and can also eliminate the exhaust gas pollution generated when the gas stove is working.

[0018] Since the refractory electric furnace plate of the round heating electric furnace wire furnace, the black crystal panel of the round electric ceramic furnace and the microcrystalline panel of the round electric ceramic furnace are all made of insulating materials, safe use can be guaranteed. High-strength refractory materials are selected to make the electric furnace plate of the round heating electric furnace wire furnace and the thickness of the electric furnace plate of the round heating electric furnace wire furnace is increased to improve the overall strength of the electric furnace plate of the round heating electric furnace wire furnace.

[0019] An effective method is adopted to eliminate the noise generated by the indoor heating device when using water vapor for heating while meeting the indoor heating requirements.

[0020] Under the above conditions, the test results show that: the distance between the bottom of the lower stainless steel drum and the top of the heating wire of the circular heating wire electric furnace is reduced from 11.5mm to 8.5mm; when the circular heating wire electric furnace is heated at a power of 500W for 47 minutes, the temperature of the top surface of the upper stainless steel drum has reached 71.6℃, and the water in the lower stainless steel drum has been reduced by 25 grams after 47 minutes of heating; a stainless steel pot with an outer diameter of 18.8cm and a height of 10.3cm including a lid weighing 645g is selected, 1000g of water is added to the pot and placed on the electric furnace plate of the 3000W electric furnace wire, the distance between the top surface of the electric furnace wire and the top surface of the refractory electric furnace plate is 4.5cm, the room temperature during the test is 19℃, the initial water temperature of the test is 17.3℃, the electric furnace is at room temperature, and the temperature is 30℃. 00W electric furnace power heating 10 minutes and 33 seconds water temperature in the pot reached 98.5 ℃ boiling start; using the above stainless steel pot and 3000W electric furnace, the heating electric furnace wire is supported by an insulated high temperature resistant threading ceramic tube and isolated refractory electric furnace plate, the contact area between the heating electric furnace wire and the refractory electric furnace plate is minimized, the top surface of the electric furnace wire is flush with the top surface of the refractory electric furnace plate, the top surface of the refractory electric furnace plate is covered with a circular electric ceramic stove microcrystalline panel with a thickness of 3.7mm and an outer diameter of 19.5cm, the bottom surface of the stainless steel pot is in contact with the circular electric ceramic stove microcrystalline panel, the same heating test initial water temperature 17.3 ℃, the electric furnace is still at room temperature, the weight is the same 1000 grams of water, the water starts to boil at 7 minutes and 27 seconds with 3000W electric furnace power, which can reduce 30% of the heating time. This temperature rise heating result obviously exceeds the heating result of choosing electromagnetic furnace heating. When the temperature of the top surface of the upper stainless steel drum is required to exceed 55°C, a scalding-proof fabric protective cover is covered on the outer surface of the heating body.

[0021] Under the same conditions as above, the heating of the circular heating wire furnace was replaced by an induction cooker. When the induction cooker was selected to heat for 47 minutes at a power of 500W, the power consumption of the two heating methods was the same. The temperature of the top surface of the upper stainless steel barrel heated by the induction cooker only reached 60.5℃. After 47 minutes of heating, the amount of water put into the lower stainless steel barrel was reduced by 20 grams. Due to the difference in the two heating methods, there are obvious differences in the heating results. The induction cooker heats intermittently. The induction cooker will generate radiation when working. Even if the induction cooker is selected with the lowest power for heating, there is still 30 to 40dB of noise. Moreover, the induction cooker can only work continuously for 3 to 4 hours. After the circular heating wire furnace is connected to the stepless temperature and voltage regulator, it enters the constant temperature heating stage and heats continuously at a set power of 200W to 250W. No noise of boiling water can be heard. Due to the 1000W The outer diameter of the heating wire of the round heating wire furnace is 4.5mm, and the depth of the groove for placing the heating wire on the electric furnace plate of a 1000W round heating wire furnace is 9.5mm. Therefore, under the condition of meeting the depth requirement for placing the heating wire of the heating wire furnace, reducing the depth of the groove for placing the heating wire on the electric furnace plate of the 1000W round heating wire furnace, and continuing to shorten the distance between the bottom of the lower stainless steel barrel and the top of the heating wire of the round heating wire furnace can further improve its heating effect.

[0022] The outdoor temperature is minus 9 degrees Celsius. The test is conducted in a room without heating. The room temperature is 15 degrees Celsius at the beginning of the test. A 1000W round heating electric furnace wire electric stove is selected to cooperate with a stepless temperature and voltage regulator, a round electric ceramic stove microcrystalline panel, an upper stainless steel barrel, a lower stainless steel barrel and water. A 3000W stepless temperature and voltage regulator is used. The 1000W round heating electric furnace wire electric stove is covered with a round electric ceramic stove microcrystalline panel with a diameter of 160mm. The size of the lower stainless steel barrel is an inner diameter of 24cm at the upper end, a height of 40cm, an outer diameter of 20.5cm at the bottom of the barrel, and a distance of 8.5mm between the bottom of the lower stainless steel barrel and the top of the heating electric furnace wire of the round heating electric furnace wire electric stove. 1060 grams of water is put into the lower stainless steel barrel, and the opening ends of the two stainless steel barrels of the upper and lower stainless steel barrels are inserted into the overlapping, sealed and connected combination. The height of the combination is 136cm, and the total weight of the overall combination is 5145 grams. A 1000W round heating electric furnace was used to heat the water in the lower stainless steel barrel. After 15 minutes of heating, the top surface of the upper stainless steel barrel was already hot. The power was reduced to 500W for heating. The room temperature was 17°C after 15 minutes of heating. The heating was continued at 500W for 30 minutes, and the temperature of the top surface of the upper stainless steel barrel reached 68°C. After continuous heating at 500W for 60 minutes, the room temperature reached 20°C. After heating at 60 minutes, the temperature of the top surface of the upper stainless steel barrel reached 69°C. After continuous heating at 500W for 90 minutes, the room temperature reached 22°C. After heating at 90 minutes, the temperature of the top surface of the upper stainless steel barrel reached 70°C. After 90 minutes of heating, the indoor temperature increased by 7 degrees.

[0023] According to the first and second technical solutions of the method for heating indoors by heating and boiling the water added to the lower stainless steel barrel to generate water vapor, which is composed of a circular heating electric furnace wire electric furnace and a stepless temperature and voltage regulator, a circular electric ceramic furnace microcrystalline panel, an upper stainless steel barrel, a lower stainless steel barrel and water, it was surprisingly found through experiments that when the circular heating electric furnace wire electric furnace and the stepless temperature and voltage regulator were turned on to heat the steamed cake with a power of 500W, when the temperature of the top surface of the upper stainless steel barrel reached 62°C, the steaming cake was heated for 20 minutes. The steamed cake was made of two layers of flour totaling three pounds. The cakes have all been steamed; in the above heating process, a circular stainless steel steaming rack made of stainless steel wires evenly spaced is placed in the lower stainless steel barrel, which is conducive to the heating of food by high-temperature steam. While heating in an ideal state, steaming steamed buns, steamed cakes, steamed sweet potatoes, steamed rice, etc. can be completed, or the lower stainless steel barrel can be used to stew various foods. A circular stainless steel grate steaming sheet with a diameter smaller than the inner diameter of the bottom of the lower stainless steel barrel is placed in the lower stainless steel barrel to isolate the food from the inner bottom of the lower stainless steel barrel to prevent the stewed food from sticking to the bottom of the lower stainless steel barrel and getting sticky when heated.

The wide application of the above indoor heating method can reduce the winter heating cost by about 60%, which will greatly reduce energy consumption and produce significant economic benefits. Since the heating device used in the present invention has a fast heating speed and low heating cost, in winter, according to the quality of the indoor air, the windows should be opened and ventilated regularly every day. The circulation and renewal of indoor air can improve and improve the quality of indoor air. DETAILED DESCRIPTION

[0035] Compared with the centralized heating method, the above-mentioned "indoor heating method" is used. The coldest time in winter in northern China each year accounts for one-third of the winter heating period; the beginning time period of the centralized heating period and the later time period of the centralized heating account for two-thirds of the winter heating period. The heating cost required in the two-thirds time period in the early and late stages of heating is relatively low. The highest temperature of the radiator in this time period is less than 40°C, and the highest temperature of the radiator reaches 40°C to 44°C during the coldest time period in winter each year. Therefore, the heating temperature and heating time are adjusted according to climate changes and respective demand conditions. The cost expenditure of the indoor heating method of the present invention during the entire heating period is compared with that of the centralized heating method, which can significantly reduce the winter heating cost.
