Technical Field

[0001] This invention relates to the field of heat source equipment, and more particularly to a fully automatic low-vacuum electric heat source equipment. Background Technology

[0002] Vacuum boilers include electrically heated vacuum boilers, oil / gas-fired vacuum boilers, and coal-fired vacuum boilers. However, existing vacuum boilers suffer from low energy efficiency, environmental pollution, and high operating costs. For example, coal-fired vacuum boilers primarily use coal as fuel, which produces harmful gases upon combustion, thus causing environmental pollution. While electrically heated and oil / gas-fired vacuum boilers can mitigate environmental pollution, their operating costs are too high. Therefore, a new type of heat source equipment is urgently needed to solve these technical problems. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0038] In this specification, the term "a plurality of" refers to two or more, and the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] like Figure 1 As shown, the fully automatic low-vacuum heat source equipment of the present invention includes a heating chamber 3, a vacuum chamber 2, a multi-functional hot water storage tank 6, a comprehensive air box 5, a first heat storage water supply device 1101, a second heat storage water supply device 1102, a third heat storage water supply device 1103, an insulated water tank 7, and a heat exchanger 12.

[0040] The heating chamber 3 has an overall shape that is wider at the top and narrower at the bottom. A first fan 4 and a multi-functional heater 401 with multiple openings are installed at the bottom of the heating chamber 3 to provide hot air. The first fan 4 is located at the opening at the bottom of the heating chamber 3, and the multi-functional heater 401 is located below the first fan 4 and fixed to the heating chamber 3, thereby providing hot air to the heating chamber 3. Inside the heating chamber 3, a glass tube electric heater 303 and a first vacuum tube 304 are installed. One end of the glass tube electric heater 303 is connected to a first circulating water pipe 301, and the other end is connected to a second circulating water pipe 305. Inside the heating chamber 3, a first hot water storage pipe 302 is installed, and the first vacuum tube 304 is sleeved on the first hot water storage pipe 302. The glass tube electric heater 303 is used to heat the water flowing through it, and the first vacuum tube 304 is used to transfer heat to the heating chamber 3. The glass tube electric heater 303 is made by spraying an electrothermal film onto a glass tube. The glass tube electric heater 303 has a power of 1KW, thus significantly reducing power consumption. The first vacuum tube 304 is filled with a heat source liquid. When heated, the heat source liquid in the first vacuum tube 304 undergoes a phase change reaction, transferring heat to the heating chamber 3 and thereby increasing the temperature of the heating chamber 3. The first vacuum tube 304 is provided with a heat source liquid injection section for injecting and sealing the heat source liquid.

[0041] Vacuum chamber 2 is positioned above heating chamber 3, with the top surface of heating chamber 3 forming the bottom surface of vacuum chamber 2. Vacuum chamber 2 is filled with a heat source liquid. Vacuum chamber 2 includes a first water tank 201, a second water tank 202, and a third water tank 203. The first water tank 201 contains a first spiral hot water storage pipe 206, the second water tank 202 contains a second spiral hot water storage pipe 207, and the third water tank 203 contains a third spiral hot water storage pipe 208. A first hot air duct 205 is installed through each water tank, with its bottom end connected to heating chamber 3. Hot air from heating chamber 3 enters the first hot air duct 205, transferring heat to the water in each tank, thus raising the water temperature in each tank. Since the top surface of heating chamber 3 forms the bottom surface of vacuum chamber 2, as the temperature of heating chamber 3 rises, the temperature of vacuum chamber 2 also rises. The heat source liquid in vacuum chamber 2 undergoes a phase change reaction upon heating, transferring heat to the water in each tank, thereby raising the water temperature in each tank. The water in the first water tank 201, the second water tank 202, and the third water tank 203 exchange heat with the water in the first spiral hot water storage pipe 206, the second spiral hot water storage pipe 207, and the third spiral hot water storage pipe 208, respectively, thereby raising the water temperature in these pipes. The first water tank 201, the second water tank 202, and the third water tank 203 can be made of stainless steel.

[0042] The first circulating water pipe 301 is connected to the first water tank 201. The first water tank 201 is connected to the second water tank 202 through the fourth connecting water pipe P4. The second water tank 202 is connected to the third water tank 203 through the fifth connecting water pipe P5. The first water tank 201 receives water from the first circulating water pipe 301, the second water tank 202 receives water from the first water tank 201, and the third water tank 203 receives water from the second water tank 202. The multi-functional hot water storage tank 6 receives water from the third water tank 203. The water in the multi-functional hot water storage tank 6 enters the second circulating water pipe 305, passes through the glass tube electric heater 303, and then enters the first circulating water pipe 301, thus completing the water circulation.

[0043] Vacuum chamber 2 is also equipped with a vacuum control valve 209 and a vacuum pump 210, used to set vacuum chamber 2 to a negative pressure environment. Vacuum chamber 2 is also equipped with a heat source liquid injection section 211, used to inject heat source liquid and seal it.

[0044] Through the coordinated action of the first hot air duct 205, the glass tube electric heater 303, and the phase change reaction of the heat source liquid in the vacuum chamber 2, the water temperature in the first water tank 201, the second water tank 202, and the third water tank 203 can be rapidly increased, resulting in high heating efficiency. Furthermore, the water in the first water tank 201, the second water tank 202, and the third water tank 203 exchanges heat with the water in the first spiral hot water storage pipe 206, the second spiral hot water storage pipe 207, and the third spiral hot water storage pipe 208, respectively, thereby raising the water temperature in these pipes.

[0045] The multi-functional hot water storage tank 6 is connected to the third water tank 203 via a sixth connecting water pipe P6. The multi-functional hot water storage tank 6 is divided into a first part and a second part, separated by a blind flange with small holes for water flow. Multiple second hot air ducts 604 are connected between the first and second parts, through which hot air is supplied. The hot air in the second hot air ducts 604 raises the water temperature in both parts to a set temperature, such as 85℃. The first part contains a fourth spiral hot water storage pipe 601, and the second part contains a fifth spiral hot water storage pipe 602 and a sixth spiral hot water storage pipe 603. The water in the first part exchanges heat with the water in the fourth spiral hot water storage pipe 601, and the water in the second part exchanges heat with the water in the fifth spiral hot water storage pipe 602 and the sixth spiral hot water storage pipe 603, thus raising the water temperature in these pipes. The multi-functional hot water storage tank 6 can be made of stainless steel.

[0046] The water in the multi-functional hot water storage tank 6 undergoes convective heat transfer with the water from the third water tank 203, thereby raising the water temperature in the multi-functional hot water storage tank 6. At the same time, hot air passes through the second hot air duct 604 of the multi-functional hot water storage tank 6 and transfers heat to the water in the multi-functional hot water storage tank 6, thereby raising the water temperature in the multi-functional hot water storage tank 6 to the set temperature, such as 85℃.

[0047] The multi-functional hot water storage tank 6 is equipped with a circulating water outlet 605, a circulating water inlet 606, and a makeup water inlet 607. Water from the third water tank 203 enters the multi-functional hot water storage tank 6 through the circulating water inlet 606, flows out from the circulating water outlet 605, and then enters the second circulating water pipe 305, thus completing the water circulation. For the makeup water inlet 607, water enters the multi-functional hot water storage tank 6 through the makeup water inlet 607 when initially filling it or when replenishing it during circulation. The opening and closing of each inlet and outlet can be controlled by adjusting the control valves.

[0048] One end of the first spiral hot water storage pipe 206 is connected to the first hot water storage pipe 302, and the other end is connected to the fourth spiral hot water storage pipe 601 through the first connecting water pipe P1. One end of the second spiral hot water storage pipe 207 is connected to the first hot water storage pipe 302, and the other end is connected to the fifth spiral hot water storage pipe 602 through the second connecting water pipe P2. One end of the third spiral hot water storage pipe 208 is connected to the first hot water storage pipe 302, and the other end is connected to the sixth spiral hot water storage pipe 603 through the third connecting water pipe P3. The first spiral hot water storage pipe 206 and the second spiral hot water storage pipe 207 are connected to the first hot water storage pipe 302, and the other end is connected to the sixth spiral hot water storage pipe 603 through the third connecting water pipe P3. 7. The third spiral hot water storage pipe 208 receives water from the first hot water storage pipe 302, the fourth spiral hot water storage pipe 601 receives water from the first spiral hot water storage pipe 206, the fifth spiral hot water storage pipe 602 receives water from the second spiral hot water storage pipe 207, and the sixth spiral hot water storage pipe 603 receives water from the third spiral hot water storage pipe 208. The water flowing out of the fourth spiral hot water storage pipe 601 is used for heating, the water flowing out of the fifth spiral hot water storage pipe 602 is used for domestic use, and the water flowing out of the sixth spiral hot water storage pipe 603 is used for showering. Preferably, the water flowing out of the sixth spiral hot water storage pipe 603 can be supplied to a vacuum shower.

[0049] One end of the second hot air duct 604 is provided with a first hot air duct fixing part 608, and the other end is provided with a second hot air duct fixing part 609. The first hot air duct fixing part 608 and the second hot air duct fixing part 609 are hollow structures used to fix the second hot air duct 604.

[0050] The multi-functional hot water storage tank 6 is equipped with a temperature controller 610, which is used to control the water temperature in the multi-functional hot water storage tank 6 within a set range, such as 85℃.

[0051] A combined air box 5 is positioned above the vacuum chamber 2. The combined air box 5 is connected to the top of the first hot air duct 205 to receive hot air from the first hot air duct 205. The combined air box 5 is equipped with a second fan 501 to deliver the hot air from the combined air box 5 to the second hot air duct 604 of the multi-functional hot water storage tank 6. The hot air discharged from the first hot air duct 205 is collected in the combined air box 5. The collected hot air then enters the first hot air duct fixing part 608 through the second fan 501 and then enters the second hot air duct 604. It then passes sequentially through the second hot air duct fixing part 609 and the sixth hot air duct 613 before being discharged to the outside of the fully automatic low-vacuum heat source equipment. Preferably, the discharged hot air can be provided to a vacuum shower to activate it.

[0052] Preferably, the first connecting water pipe P1, the second connecting water pipe P2, and the third connecting water pipe P3 are partially installed inside the integrated air box 5 to utilize the hot air in the integrated air box 5 to prevent the water temperature in each connecting water pipe from dropping.

[0053] The first thermal water storage and replenishment device 1101, the second thermal water storage and replenishment device 1102, and the third thermal water storage and replenishment device 1103 each have a double-layer structure, including an inner layer and an outer layer. Each inner layer has multiple holes, allowing water from the outer layer to slowly flow into it. Each inner layer receives water from the third water tank 203. The outer layers of the second and third thermal water storage and replenishment devices 1102 and 1103 receive domestic cold water, while the outer layer of the first thermal water storage and replenishment device 1101 receives heating return water. The domestic cold water or heating return water from the outer layer slowly flows into the inner layer through the multiple holes and mixes with the water in the inner layer, thereby preventing the water temperature in the thermal water storage and replenishment devices from dropping too quickly.

[0054] Once the water temperature in the multi-functional hot water storage tank 6 reaches the set temperature, the insulated water tank 7 receives water from the third water tank 203, thereby raising the water temperature in the insulated water tank 7 to the set temperature, for example, 80℃. After the water temperature in the insulated water tank 7 reaches the set temperature, the water in the insulated water tank 7 enters the second circulating water pipe 305 through the heat exchanger 12. At the same time, the water flowing out from each heat storage water supply device enters the first hot water storage pipe 302 through the heat exchanger 12, thereby exchanging heat in the heat exchanger 12.

[0055] The insulated water tank 7 is located behind the vacuum chamber 2 and the multi-functional hot water storage tank 6. The insulated water tank 7 is equipped with an automatic full-water control device 701 for automatically controlling the water volume. The insulated water tank 7 also has a circulating water outlet / replenishment inlet 703, a circulating water inlet 702, and a drain outlet 705. The circulating water outlet / replenishment inlet 703 serves as the replenishment inlet when water is initially added to the insulated water tank 7 or when replenishment is needed during circulation. Water from the main inlet pipe enters the insulated water tank 7 through the circulating water outlet / replenishment inlet 703 to add or replenish water. When the insulated water tank 7 participates in circulation, it serves as the circulating water outlet. Water from the third water tank 203 enters through the circulating water inlet 702 and flows out through the circulating water outlet / replenishment inlet 703. The opening and closing of each inlet and outlet can be controlled by adjusting the control valves. When the insulated water tank 7 participates in the circulation, it receives water from the third water tank 203, thereby raising the water temperature in the insulated water tank 7. After the water temperature in the insulated water tank 7 reaches the set temperature, for example, 80°C, the water in the insulated water tank 7 enters the second circulating water pipe 305 through the heat exchanger 12. At the same time, the water flowing out from each heat storage water supply device enters the first heat storage water pipe 302 through the heat exchanger 12, thereby exchanging heat in the heat exchanger 12.

[0056] The insulated water tank 7 is equipped with a temperature controller 704, which is used to control the water temperature in the insulated water tank 7 within a set range, such as 80℃.

[0057] After the water temperature in the multi-functional hot water storage tank 6 reaches the set temperature, the water in the third water tank 203 flows into the insulated water tank 7. After the water temperature in the insulated water tank 7 reaches the set temperature, the water in the insulated water tank 7 enters the heat exchanger 12 to exchange heat with the water from each heat storage water supply device. After heat exchange in heat exchanger 12, the water in insulated water tank 7 sequentially enters the second circulating water pipe 305, the glass tube electric heater 303, the first circulating water pipe 301, the first water tank 201, the second water tank 202, the third water tank 203, and the inner layer of each heat storage water supply device. Water from each heat storage water supply device, after heat exchange in heat exchanger 12, enters the first hot water storage pipe 302, then the first spiral hot water storage pipe 206, the second spiral hot water storage pipe 207, and the third spiral hot water storage pipe 208, and then the fourth spiral hot water storage pipe 601, the fifth spiral hot water storage pipe 602, and the sixth spiral hot water storage pipe 603. The water flowing out of the fourth spiral hot water storage pipe 601 is used for heating, the water flowing out of the fifth spiral hot water storage pipe 602 is used for domestic use, and the water flowing out of the sixth spiral hot water storage pipe 603 is used for showering. During this process, the inflow and outflow of water can be controlled by a control valve.

[0058] The fully automatic electric low-vacuum heat source equipment also includes an expansion tank 14, which is used to contain the expanding water and air from the first water tank 201, the second water tank 202, and the third water tank 203. The expansion tank 14 is equipped with a second exhaust pipe 1401. Each water tank is equipped with a first exhaust pipe 212 on its top. One end of each first exhaust pipe 212 is connected to the respective water tank, and the other end is connected to the expansion tank 14. When the water in each water tank is heated and expands, the expansion tank 14 can contain the resulting expanding water and can also receive the air in each water tank and discharge it to the outside of the fully automatic electric low-vacuum heat source equipment through the second exhaust pipe 1401.

[0059] The various structures of the fully automatic electric low-vacuum heat source equipment can be made of stainless steel, and the water pipes can also be made of copper.

[0060] The fully automatic electric low-vacuum heat source equipment also includes a first water pump 15 and a second water pump 16. The first water pump 15 is used for the circulation of heating water, and the second water pump 16 is used for the circulation between the first water tank 201, the second water tank 202, the third water tank 203, the multi-functional hot water storage tank 6, and the insulated water tank 7.

[0061] Preferably, the bottoms of the first water tank 201, the second water tank 202, and the third water tank 203 are each provided with multiple U-shaped water pipes 204 that are connected to them. Through the hot air in the heating chamber 3, the water temperature in the U-shaped water pipes 204 rises, thereby raising the water temperature in each of the water tanks. Optionally, the U-shaped water pipes 204 are made of copper, which has excellent thermal conductivity.

[0062] Preferably, the bottom end of the first hot air duct 205 expands outward to form at least three hot air inlets 2051, and the hot air in the heating chamber 3 enters the first hot air duct 205 through the hot air inlets 2051.

[0063] Preferably, a second electric heater 611 is fitted onto the outer surface of the first part to heat the water in the first part. A second vacuum tube 612 is fitted onto each portion of the second hot air duct 604 located in the second part to transfer heat to the water in the second part. The second vacuum tube 612 is filled with a heat source liquid. Hot air passes through the second hot air duct 604 and transfers heat to the interior of the second vacuum tube 612. The heat source liquid in the second vacuum tube 612 undergoes a phase change reaction upon heating, transferring heat to the water in the second part, thereby further increasing the heating rate of the water in the second part. The second vacuum tube 612 is provided with a heat source liquid injection section to inject and seal the heat source liquid. By incorporating the second electric heater 611, the heating rate of the water in the first part is further increased, thus ensuring the supply of heating water. The second electric heater 611 is made by spraying an electrothermal film onto the outer surface of the second part. The power of the second electric heater 611 is 1KW, thereby significantly reducing power consumption.

[0064] When the fully automatic low-vacuum heat source equipment is started for the first time, the second electric heater 611 starts working, the water temperature in the first part rises rapidly, and then the water temperature in the fourth spiral hot water storage pipe 601 rises rapidly, thereby achieving the effect of timely heating.

[0065] In this invention, the power of the glass tube electric heater 303 and the second electric heater 611 is only 1KW. Compared with the prior art, the power consumption required by the fully automatic low vacuum heat source equipment of this invention is very low, thereby greatly reducing the cost of electricity.

[0066] Preferably, the heat source liquid comprises potassium sulfate, potassium dichromate, anhydrous ethanol, and distilled water. The mass percentage ratio of potassium sulfate (K₂SO₄), potassium dichromate (K₂Cr₂O₇), anhydrous ethanol (CH₂CH₂OH), and distilled water is 0.6:5:9.4:85. The heat source liquid vaporizes at 30°C, and the temperature of the gas produced after vaporization is 350°C–400°C. The heat source liquid is filled to 15% of the volume of the vacuum chamber 2 through the heat source liquid injection section 211 and then sealed. The vacuum chamber 2 is then set to a negative pressure environment by the vacuum pump 210. As the temperature of the heating chamber 3 rises, the heat source liquid in the vacuum chamber 2 undergoes a phase change reaction. The phase change reaction process of the heat source liquid in vacuum chamber 2 is as follows: The heat source liquid in vacuum chamber 2 vaporizes, and the resulting gas condenses on the walls of the first water tank 201, the second water tank 202, and the third water tank 203, transferring heat to the inside of the water tanks. After releasing heat, the gas condenses into liquid and falls down, where it is reheated and vaporized, thus continuously heating the water in the water tanks. The heat source liquid in the first vacuum tube 304 undergoes a phase change reaction in the following manner: The hot water generated after heat exchange in heat exchanger 12 enters the first hot water storage tube 302, transferring heat to the inside of the first vacuum tube 304. The heat source liquid in the first vacuum tube 304 vaporizes after being heated, and the resulting gas condenses on the inner wall of the first vacuum tube 304, transferring heat to the outside of the first vacuum tube 304. After releasing heat, the gas condenses into liquid and falls down, where it is reheated and vaporized, thus continuously transferring heat to the outside of the first vacuum tube 304. The heat source liquid in the second vacuum tube 612 is vaporized by hot air in the second hot air duct 604. The other processes are similar to those in the first vacuum tube 304 and will not be described in detail here. The heat source liquid can be used for decades after injection, thus the operating cost is low.

[0067] Preferably, the fully automatic electric low-vacuum heat source device of the present invention further includes at least one of a third hot air duct 8, a fourth hot air duct 9, and a fifth hot air duct 10. One end of each of the third, fourth, and fifth hot air ducts is connected to the heating chamber 3, and the other end extends to the outside of the fully automatic electric low-vacuum heat source device. Hot air in the heating chamber 3 is delivered to the outside of the fully automatic electric low-vacuum heat source device through at least one of the third, fourth, and fifth hot air ducts 8 and 9. This hot air can be provided to various vacuum heating devices, thereby activating the vacuum heating devices. Vacuum heating devices include, but are not limited to, vacuum warm air blowers, vacuum hot air curtains, and vacuum radiators.

[0068] Preferably, the third hot air duct 8 and the fourth hot air duct 9 extend from the heating chamber 3 through the vacuum chamber 2 and extend to the outside of the fully automatic electric low vacuum heat source equipment. When hot air passes through the third hot air duct 8 and the fourth hot air duct 9, it can increase the reaction rate of the heat source liquid in the vacuum chamber 2, thereby increasing the rate of temperature rise of the water in the first water tank 201, the second water tank 202, and the third water tank 203.

[0069] The fully automatic electric low vacuum heat source equipment includes a housing 1, with fresh air inlets 101 at the top and bottom. External air enters the fully automatic electric low vacuum heat source equipment through the fresh air inlets 101.

[0070] refer to Figure 2 The back of the outer casing 1 is provided with a hook 103 for fixing the fully automatic electric low vacuum heat source equipment to the wall or other locations where the fully automatic electric low vacuum heat source equipment needs to be installed.

[0071] Preferably, at least one portion of the third hot air duct 8, the fourth hot air duct 9, and the fifth hot air duct 10 is disposed inside the insulated water tank 7. When hot air passes through at least one of the third hot air duct 8, the fourth hot air duct 9, and the fifth hot air duct 10, the water temperature in the insulated water tank 7 rises through heat conduction, thereby increasing the rate of temperature rise in the insulated water tank 7. The outer surface of the insulated water tank 7 is provided with an insulation layer 706 to keep the insulated water tank warm.

[0072] refer to Figure 2 and Figure 3 The fully automatic electric low-vacuum heat source device of the present invention further includes: a fully automatic control panel 17, used to control the operating status of the fully automatic electric low-vacuum heat source device. A portion of the front of the outer casing 1 is recessed inward to form a receiving space, in which the fully automatic control panel 17 is received. A front cover 102 is provided on the front of the outer casing 1 to protect the outer casing 1 and the fully automatic control panel 17. The fully automatic electric low-vacuum heat source device of the present invention achieves automation by controlling the overall operating status through the fully automatic control panel 17.

In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed in this specification, but includes all technical solutions falling within the scope of the claims.
