Description

Technical Field

[0001] The present invention relates to the technical field of heating, and particularly relates to an electric heating furnace. Background Art

[0002] An electric heating furnace, also known as an electric heating stove, with the full name of an electric heating boiler and the technical term of an electric hot water boiler, is a heating device that converts electrical energy into heat energy to directly release heat or circulates through a heat medium in heating pipelines to meet the heating demand. It belongs to the category of electric hot water boilers. Electric heating boilers can be divided into ceramic heating tube electric heating boilers and stainless steel heating tube electric heating boilers according to different heating tubes, and can be divided into normal pressure electric heating boilers and pressurized electric heating boilers according to whether they are pressurized. The installation and use of pressurized electric heating boilers need to be supervised by the technical supervision department, and they are not as safe as normal pressure electric heating boilers. Therefore, more and more units and families choose electric heating boilers.

[0003] When hot water is used in an electric heating furnace, water flows in from the inlet into the interior of the heating water pipe, is heated, and then directly flows out through the outlet. As a result, due to a large amount of water consumption, tap water cannot be heated at a constant temperature in time, and the heating is not sufficient, resulting in insufficient temperature and affecting water use. At the same time, scale will form on the inner wall of the heating water pipe due to long-term closed heating, which will affect the heating speed. At the same time, when the heating water pipe heats the interior, the heating water pipe will dissipate heat to the outside, resulting in overheating inside and affecting the use of electronic devices, and it is also a waste of dissipated heat energy.

The water inlet pipe is connected to the inside of the connecting groove through the water inlet and is connected to the outside.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) The electric heating furnace facilitates the control of the water valve inside the main body by setting round holes, blocks the air vent window at the top of the water storage tank through the arranged closing plate, and avoids excessive temperature and pressure inside the water storage tank by setting the air vent window, preventing excessive heat absorption of the water inside the water storage tank from spreading to the inside of the main body. Heat can be discharged through the air vent window. When the water inside the water storage tank needs to be used, the closing plate can be blocked on the surface of the air vent window. The water storage tank is used to fix the positions of the heating water pipe and the heating plate structure, and at the same time, it is used to isolate the heating plate structure from the control structure, avoiding damage to the electronic components of the control structure due to the excessive temperature of the heating plate structure. At the same time, by adding cold water into the water storage tank, the temperature diffused from the heating plate structure and the inside of the heating water pipe can be absorbed, preventing the excessive temperature from directly spreading to the inside of the main body, thus causing damage to the electronic components, thereby playing a role in heat absorption and temperature reduction. At the same time, the heat-absorbed water can be utilized, and the waste of excess heat energy is avoided.

[0015] (2) The electric heating furnace heats the tap water flowing through the heating water pipe by setting a heating plate structure. Moreover, due to the shape of the heating water pipe, the time that the tap water stays in the heating water pipe is increased, enabling deeper heating of the tap water. At the same time, the heating sheet of the heating plate structure can directly heat the tap water. When the water flow passes through the heating water pipe, the flow is disrupted by the turbulence blocks on the heating sheet, making the heated temperature more uniform and sufficient. By setting through holes, the water in the water storage tank can flow to the back of the heater, enabling the water entering the water storage tank to be evenly distributed inside the water storage tank.

[0016] (3) The electric heating furnace enables the water flow to be stirred through the connection structure, making the temperature inside the water flow more uniform. In cooperation with the turbulence blocks, the stirring amplitude of the water flow is increased, enabling the water flow passing through the connection structure to be greatly dispersed. Through the cooperation of the cleaning structure and the connection structure, the inside of the heating water pipe can be cleaned by adding water, preventing scale generated on the inner wall of the heating water pipe and the heating sheet due to long-term closed heating inside the heating water pipe from continuously adhering to the inner walls of the heating water pipe and the heating sheet, thus avoiding affecting the heating speed. The water flow at different positions can be disrupted by the first turbulence plate and the second turbulence plate, preventing the inability to disrupt the flow due to space limitations.

At the same time, the water flow enters the heating water pipe 12 through the first water inlet pipe 401. After heating, it flows through the water outlet 5 to the position where the faucet discharges water. When discharging water, the water outlet controller 501 releases the water flow with sufficient temperature to prevent the water flow with insufficient heating temperature from flowing out of the electric heating furnace. When adding water into the water storage tank 11, the water valve 403 on the second part of the first water inlet pipe 401 is opened through the round hole 3, and the water outlet controller 501 is in a closed state, so that the water flow enters the first water inlet pipe 401 and then enters the water storage tank 11 through the second part of the first water inlet pipe 401. When using the water in the water storage tank 11, the water valve 403 of the first water outlet pipe 502 is opened, and the hot water flows through the first water outlet pipe 502 to the outside for use.
