Description

Technical Field

[0001] This utility model relates to a thermal storage type floor-standing oil-fired water heater, belonging to the field of water heater technology. Background Technology

[0002] Currently, most household water heaters on the market use electricity or gas as their heat source, while oil-fired water heaters have not yet been widely used in the civilian sector. Traditional water heaters have significant limitations when used in remote areas or places with unstable gas or electricity supplies: electric water heaters rely on a stable power supply, and gas water heaters require supporting gas pipeline infrastructure. Oil, as a high-calorific-value and easily stored energy source, has not yet been fully developed in the water heater field. Existing technology lacks a floor-standing water heater unit that can fully utilize oil energy, has a complete circulating heating system, and is easy to install and use. Especially in cold regions or special environments such as field operations, there is an urgent need for a water heater solution that does not rely on the power grid or gas pipeline network and can achieve stable heating. Utility Model Content

[0005] The fuel burner is connected to a flue pipe that passes through an inner liner. The high-temperature flue gas is discharged after exchanging heat with the cooler water in the inner liner, thus absorbing and utilizing the waste heat of the flue gas.

[0006] In addition, a three-way pipe is connected to the end of the flue pipe. The upper end of the three-way pipe is the flue outlet, and the lower end of the three-way pipe is connected to the liquid collector.

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] In existing technologies, traditional water heaters mainly rely on electricity or gas as heat sources, making it difficult to provide continuous heating in areas lacking a stable power supply or gas pipeline coverage. There is an urgent need for independently powered hot water equipment in remote areas, field work sites, or temporary buildings, but current technologies cannot provide heating devices that can operate independently of the power grid and gas pipeline network.

[0019] To address the aforementioned issues, considering the advantages of fuel oil in terms of energy density and ease of storage, constructing a closed-loop water circulation system based on fuel oil combustion has become a key breakthrough direction. By integrating the fuel oil burner into an independent circulation pipeline and configuring a circulation pump to maintain water flow, a heating system is formed, ultimately achieving the ability to supply hot water independently of the power grid and gas pipeline network.

[0020] Therefore, this application proposes a thermal storage type floor-standing oil-fired water heater, such as... Figures 1-3As shown, the system includes an inner tank 7 connected to an external circulation heating pipeline. The external circulation heating pipeline is equipped with a fuel burner 1 for heating the water and a circulation pump 12 for providing circulation power to the water. The external circulation heating pipeline is a fluid channel independent of the inner tank 7 body, including a circulation outlet pipe 10, a circulation riser pipe 14, and a circulation inlet pipe 2. The pipe body can be made of high-temperature resistant metal tubing, connected to form a closed loop, realizing directional circulation of water between the burner heating area and the inner tank water storage space. The burner heating area integrates a heat exchange structure.

[0021] The fuel burner 1 is a device that generates heat through combustion by atomizing or vaporizing fuel, converting the chemical energy of the fuel into heat energy and transferring it to the water flowing through the pipeline. The fuel burner 1 is connected to a fuel inlet pipeline, which is equipped with a fuel pump and connected to a fuel tank (not shown in the figure).

[0022] The inner tank 7 is equipped with a cold water inlet 13 and a hot water outlet 15. The cold water inlet 13 is located at the water source inlet at the bottom of the inner tank 7, and can be connected to the water supply pipe via a flange. The hot water outlet 15 is located at the water intake port at the top of the inner tank 7, and can be controlled by an electric valve to control the hot water output. A drain outlet is also provided at the bottom of the inner tank 7.

[0023] The hot water outlet 15 is higher than the cold water inlet 13. After the water inside the inner tank is heated, the density decreases and it rises. The hot water gathers in the top area and is stably output through the high outlet. The cold water enters the bottom of the inner tank through the low inlet and gradually fills the tank under the action of gravity, forming a layer with the upper hot water. This reduces the temperature fluctuation caused by direct mixing of hot and cold water.

[0024] The fuel burner 1 is connected to a flue pipe 16, which passes through the inner liner 7. The water stored in the inner liner 7 absorbs the residual heat transferred by the flue pipe 16, thereby reducing heat loss and further heating the water in the inner liner 7. The flue pipe 16 can be configured to pass through the inner liner in a spiral or zigzag shape to increase the heat exchange area.

[0025] A tee pipe is connected to the end of flue pipe 16. The upper end of the tee pipe is the flue outlet 8, and the lower end is connected to a liquid collector 9. The tee pipe is used to divide the airflow path at the end of the flue pipe into two directions. When the flue gas generated by the oil burner 1 is discharged to the outside through flue pipe 16, the water vapor in the flue gas forms condensate after the temperature decreases at the end of the flue pipe. The flue outlet 8 at the upper end of the tee pipe keeps the flue gas discharge channel unobstructed, and the flue outlet 8 can be connected to the exhaust pipe. The liquid collector connected at the lower end continuously collects the condensate. When the equipment stops operating, the liquid stored inside the liquid collector 9 can be discharged through the bottom valve or disassembled for discharge.

[0026] The top of the inner liner 7 is equipped with a pressure gauge 3, a vent valve 4, and a safety valve 5.

[0027] Among them, pressure gauge 3 is an instrument used to monitor the internal pressure of the inner liner. Specifically, it can be implemented by a mechanical pressure gauge or an electronic pressure sensor. By displaying the pressure value in real time, it is easy for operators to judge the operating status of the inner liner.

[0028] Among them, the vent valve 4 is a valve used to discharge the gas accumulated inside the inner liner. Specifically, it can be implemented by using an electromagnetically driven automatic vent valve, which prevents abnormal pressure rise by periodically discharging gas.

[0029] Among them, safety valve 5 refers to the device that automatically opens to release pressure when the pressure in the inner tank exceeds the set threshold. Specifically, it can be implemented by using a spring-loaded safety valve or a rupture disc safety device, which prevents the inner tank from being damaged due to overpressure through a pressure triggering mechanism.

[0030] The support leg 11 is a load-bearing component installed at the bottom of the water heater to support the overall structure. It can be made of metal or engineering plastic to provide stable bottom support for the water heater. The height of the support leg can be adjusted through a threaded structure or shims to adapt to different ground flatness and ensure that the water heater is placed horizontally.

[0031] The inner liner 7 is surrounded by an outer cover 17, which is a shell structure that wraps around the inner liner 7. It can be made of metal sheet or engineering plastic to form a closed space to accommodate the insulation material. The outer cover 17 has recessed handles 18 on both sides. The insulation material is filled between the outer cover 17 and the inner liner 7. It can be made of rock wool, glass fiber or polyurethane foam. By reducing the heat exchange between the inner liner 7 and the outside, heat loss is reduced.

[0032] The inner liner 7 is provided with a magnesium rod inlet 6, which can be inserted into the inner liner 7 to prevent corrosion of the inner liner 7 through sacrificial anode.

[0033] The fuel burner 1 heats the water flowing through the external circulation pipeline using the heat released from combustion. The circulation pump 12 continuously circulates the water between the pipeline and the inner tank 7, forming a dynamic heating process. Fuel is delivered to the burner via the fuel pump for atomization or vaporization combustion. Cold water enters the inner tank through the low-level water inlet, and the heated water is output from the high-level water outlet. The inner tank 7 acts as a heat storage container to maintain a stable water temperature, while the external circulation system enables continuous heat exchange and replenishment.

[0034] Compared with existing technologies, traditional electric water heaters are limited by the coverage of the power grid, and gas water heaters rely on pipeline infrastructure. This solution, however, combines fuel combustion with an independent circulation system to build a completely autonomous energy supply system. Furthermore, by combining the flue and the inner tank, waste heat from exhaust gas is used to heat the water, improving energy efficiency. At the same time, no additional waste heat recovery device is required, simplifying the system structure.

[0035] Through the above technical solution, this application can achieve stable hot water output in environments without power grid or gas supply. The overall structure is adapted to the needs of ground installation, providing a reliable hot water supply solution for special scenarios such as field operations and temporary buildings.
