Description

Technical Field

[0001] This invention belongs to the field of water heaters, and particularly relates to an energy-saving solar gas water heater. Background Technology

[0002] As living standards continue to improve, people's demands in all aspects are also increasing, especially in bathing. Water heaters that provide instant hot water at a constant temperature are gaining increasing attention and popularity across all income levels. Currently, the most common water heaters on the market are divided into three categories: solar water heaters, electric water heaters, and gas water heaters. Solar water heaters rely heavily on weather conditions, so the stability of their hot water supply is often unreliable. Electric water heaters are affected by power supply fluctuations, frequently impacting their use. Gas water heaters, on the other hand, have the disadvantage of consuming excessive energy. The current practice is usually to use solar water heaters in combination with either gas or electric instantaneous water heaters.

[0003] In existing solar-powered gas water heaters, when the temperature inside the storage tank becomes too high and the gas pressure increases, the excess heat is released through the exhaust valve along with the gas, resulting in heat waste and hindering energy conservation and environmental protection.

[0004] To avoid the aforementioned technical problems, it is indeed necessary to provide an energy-saving solar gas water heater to overcome the deficiencies in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving solar gas water heater, which aims to solve the problem of waste caused by excess heat discharge.

[0006] This invention is implemented as follows: an energy-saving solar-gas water heater includes a solar water heater body, on which an exhaust valve and inlet / outlet water pipes are provided. One end of the inlet / outlet water pipes is connected to a water supply pipe and a hot water outlet pipe. The invention also includes:

[0007] A heating component is disposed in the middle of the hot water outlet pipe, and the heating component can heat the hot water outlet pipe by burning gas;

[0008] A heat storage component includes an insulated box, which is connected to an exhaust valve via a first vent pipe. The outside of the first vent pipe is wrapped with insulation cotton. One end of the first vent pipe extends into the interior of the insulated box, and a second one-way valve is provided between the first vent pipe and the insulated box. The interior of the insulated box contains a heat storage medium for absorbing and storing heat discharged from the exhaust valve. The side of the insulated box away from the first vent pipe is connected to a heating component via a second vent pipe, which is also wrapped with insulation cotton. The heat storage medium can reuse heat by allowing the released heat to enter the heating component.

[0009] In a further technical solution, the main body of the solar water heater also includes a bracket, a vacuum collector tube, a water storage tank, and a drain pipe. The vacuum collector tube and the water storage tank are both mounted on the bracket, and the vacuum collector tube is connected to the interior of the water storage tank. The inlet and outlet water pipes and the drain pipe are both connected to the water storage tank. The vent valve is installed on the water storage tank, and a first temperature sensor is also installed inside the water storage tank.

[0010] In a further technical solution, a flow meter is connected to the middle of the inlet and outlet water pipes, and a first solenoid valve is provided at the end of the water supply pipe near the flow meter.

[0011] A further technical solution includes a heating shell, which is fixed in the middle of the hot water outlet pipe, and one end of the second gas pipe extends into the interior of the heating shell. A gas stove is installed at the bottom of the heating shell, and the gas inlet of the gas stove is connected to an inlet pipe that passes through the heating shell. The exhaust port of the gas stove is connected to an exhaust pipe, and one end of the exhaust pipe extends outside the heating shell. A second temperature sensor is installed at the end of the hot water outlet pipe that is away from the flow meter and close to the heating shell. A third solenoid valve is installed in the middle of the hot water outlet pipe.

[0012] In a further technical solution, the inner wall of the heating shell is provided with a heat insulation layer, the heat insulation layer is filled with heat insulation material, the hot water outlet pipes located inside the heating shell are distributed in an "S" shape, and heat-conducting plates are provided between the "S" shaped hot water outlet pipes.

[0013] In a further technical solution, the interior of the insulation box is provided with multiple racks, all of which are honeycomb structures, and the heat storage medium is placed inside the multiple racks.

[0014] In a further technical solution, an exhaust fan is provided in the middle of the second air guide pipe located on one side of the second solenoid valve, and a first one-way valve is provided on the side of the insulation box.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention provides an energy-saving solar gas water heater. When the water in the storage tank boils, the pressure in the tank increases, which opens the exhaust valve. A large amount of heat is released from the exhaust valve along with the excess gas. The released gas enters the insulation box through the first air guide pipe. The heat storage medium absorbs and stores the heat, thus recovering the heat and avoiding waste. When the exhaust fan is turned on, cold outside air enters the insulation box, lowering the temperature inside. Under the influence of the large temperature difference, the heat storage medium releases heat. The heat enters the heating shell through the second air guide pipe, heating the hot water outlet pipe. This achieves the recycling of excess heat, making the device more energy-efficient. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] like Figure 1-4 As shown, this invention provides an energy-saving solar-gas water heater, comprising a solar water heater body 1, on which an exhaust valve 106 and inlet / outlet water pipes 104 are provided. One end of the inlet / outlet water pipes 104 is connected to a water supply pipe 5 and a hot water outlet pipe 6. The invention also includes:

[0025] Heating component 7 is disposed in the middle of hot water outlet pipe 6, and the heating component 7 can heat hot water outlet pipe 6 by burning gas;

[0026] The heat storage component 2 includes an insulation box 21, which is connected to an exhaust valve 106 via a first air duct 3. One end of the first air duct 3 extends into the interior of the insulation box 21, and a second one-way valve is provided between the first air duct 3 and the insulation box 21. The interior of the insulation box 21 contains a heat storage medium, which is used to absorb and store the heat discharged from the exhaust valve 106. The side of the insulation box 21 away from the first air duct 3 is connected to the heating component 7 via a second air duct 8. A second solenoid valve is provided at the end of the second air duct 8 near the insulation box 21, and the outside of the second air duct 8 is wrapped with insulation cotton. The heat storage medium can reuse the heat by allowing the released heat to enter the heating component 7.

[0027] When the water temperature in the main body 1 of the solar water heater rises, excess heat is discharged from the exhaust valve 106 along with the gas. The heat enters the insulation box 21 through the first air guide pipe 3, where the heat storage medium absorbs and stores the heat, avoiding heat waste. When the water temperature in the main body 1 of the solar water heater is too low, the heating component 7 is used to heat the hot water outlet pipe 6, while the heat storage medium releases heat. The heat enters the interior of the heating component 7 through the second air guide pipe 8, improving heating efficiency and realizing the recycling of excess heat. This device can heat and use at the same time, making it more convenient to use.

[0028] In embodiments of the present invention, such as Figure 1-2 As shown, in a preferred embodiment of the present invention, the main body 1 of the solar water heater further includes a bracket 101, a vacuum collector tube 102, a water storage tank 103, and a drain pipe 105. The vacuum collector tube 102 and the water storage tank 103 are both mounted on the bracket 101, and the vacuum collector tube 102 is connected to the interior of the water storage tank 103. The inlet and outlet water pipes 104 and the drain pipe 105 are both connected to the water storage tank 103. The exhaust valve 106 is provided on the water storage tank 103. A first temperature sensor is also provided inside the water storage tank 103.

[0029] Water is added to the water storage tank 103 through the inlet / outlet pipe 104. The vacuum heat collector tube 102 is irradiated by sunlight, which heats the water in the water storage tank 103. When the temperature in the water storage tank 103 is too high, the liquid water turns into gaseous water, and the gas pressure in the water storage tank 103 increases. The greater pressure will open the exhaust valve 106, thereby releasing gas. The heat is discharged with the gas. The drain pipe 105 prevents too much water from being added to the water storage tank 103.

[0030] In embodiments of the present invention, such as Figure 1-2 As shown, in a preferred embodiment of the present invention, a flow meter 4 is connected to the middle of the inlet and outlet water pipes 104, and a first solenoid valve is provided at one end of the water supply pipe 5 near the flow meter 4.

[0031] Water supply pipe 5 replenishes water to water storage tank 103, and hot water outlet pipe 6 is used to discharge hot water.

[0032] In embodiments of the present invention, such as Figure 1-2 and Figure 4 As shown, in a preferred embodiment of the present invention, the heating assembly 7 includes a heating shell 71, which is fixed to the middle of the hot water outlet pipe 6, and one end of the second gas guide pipe extends into the interior of the heating shell 71. A gas stove 72 is provided at the bottom of the heating shell 71, and the gas inlet of the gas stove 72 is connected to an inlet pipe 73, which penetrates the heating shell 71. The exhaust port of the gas stove 72 is connected to an exhaust pipe 74, one end of which extends to the outside of the heating shell 71. A second temperature sensor 9 is provided at the end of the hot water outlet pipe 6 that is away from the flow meter 4 and close to the heating shell 71. A third solenoid valve is provided in the middle of the hot water outlet pipe 6.

[0033] When heating, gas is supplied to the gas stove 72 and the switch of the gas stove 72 is turned on. The gas stove 72 can then heat the hot water outlet pipe 6, and the second temperature sensor 9 monitors the water temperature in real time.

[0034] In embodiments of the present invention, such as Figure 4 As shown, in a preferred embodiment of the present invention, the inner wall of the heating shell 71 is provided with a heat insulation layer, and the heat insulation layer is filled with heat insulation material to prevent heat loss and improve heating efficiency. The hot water outlet pipes 6 located inside the heating shell 71 are distributed in an "S" shape, and heat-conducting plates 75 are provided between the "S" shaped hot water outlet pipes 6 to improve heat transfer and reduce heating time.

[0035] In embodiments of the present invention, such as Figure 3 As shown, in a preferred embodiment of the present invention, the heat preservation box 21 is provided with multiple placement racks 22 inside, all of which are honeycomb structures. The heat storage medium is placed inside the multiple placement racks 22, which improves the space utilization of the heat preservation box 21, enabling the heat preservation box 21 to store more heat and improve the heat storage efficiency.

[0036] In embodiments of the present invention, such as Figure 3 As shown, in a preferred embodiment of the present invention, the second air guide pipe 8 is provided with an exhaust fan 10 in the middle of the side of the second solenoid valve, and the side of the heat preservation box 21 is provided with a first one-way valve 11.

[0037] When the exhaust fan 10 is turned on, it draws air from the insulation box 21. Under atmospheric pressure, outside air enters the insulation box 21 through the first one-way valve 11, causing the temperature inside the insulation box 21 to drop. The heat storage medium releases heat, and the heat is carried by the air through the second air pipe 8 into the heating shell 71 to heat the hot water outlet pipe 6.

[0038] During use, water supply pipe 5 replenishes water to water storage tank 103, and vacuum heat collection tube 102 heats the water in water storage tank 103. When the temperature in water storage tank 103 is too high, the liquid water turns into gaseous water, and the gas pressure in water storage tank 103 increases. The higher pressure will open the exhaust valve 106, thereby releasing gas. The heat is discharged with the gas. The discharged heat enters the heat storage box 21 through the first gas guide pipe 3. The heat storage medium in the heat storage box 21 absorbs and stores the heat. When the weather is bad and the temperature of the water in water storage tank 103 is low, the valve opens... The gas stove 72 heats the hot water outlet pipe 6. At the same time, the exhaust fan 10 is turned on, which draws air from inside the insulation box 21. Under atmospheric pressure, cold outside air enters the insulation box 21 through the first one-way valve 11, thereby lowering the temperature inside the insulation box 21 and causing the heat storage medium to release heat. The heat enters the heating shell 71 through the second air guide pipe 8 to heat the hot water outlet pipe 6. This improves heating efficiency and also recycles excess heat, reducing gas consumption. The device is more energy-efficient.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
