Description

TECHNICAL FIELD

[0001] The utility model belongs to heat energy conversion technical field, concretely relates to a heat energy converter with self -cleaning function. BACKGROUND

[0002] The electric heating type heating stove circulating in the market generally uses electric heating equipment to directly heat the cold water in the circulating system, thereby changing the cold water into hot water, and the hot water flows in the terminal heating equipment, thereby achieving the purpose of heating. The hot water outlet of the existing heating stove is connected with the water inlet of the radiator through a hot water pipeline, and the backwater outlet of the heating stove is connected with the water outlet of the radiator through a backwater pipeline. The electric heating rod is an electric heating rod with a working voltage of 380V. Since the water is heated to boiling at a maximum of 99 degrees Celsius, the heat energy is greatly lost during the cold water circulation process. Moreover, the water temperature rises very slowly because the cold water is being heated all the time. In fact, this heating method is a high-power consumption and low-heat production method, and the stainless steel electric heating rod may be corroded and cause electric leakage.

[0003] Therefore, a heat energy converter for heating, with publication number "CN108954470A", includes a shell, a combustion heating chamber and a gas heat exchange chamber are arranged inside the shell, and a partition plate is arranged between the combustion heating chamber and the gas heat exchange chamber in a whole space. The combustion heating chamber is heated by electricity to raise the temperature, which vaporizes the water inside to produce water vapor. The water vapor rises and exchanges heat with the water in the gas heat exchange chamber, and then enters the external circulating system through the water outlet. After the water vapor enters the gas heat exchange chamber, it rapidly exchanges heat with the cold water in the gas heat exchange chamber, and then enters the external circulating system after reaching the highest replaceable water temperature at the water outlet. When the water vapor meets the newly introduced cold water through the water inlet, it will condense into water and drop into the combustion heating chamber. Under the action of the combustion heating chamber, the water is continuously heated to form water vapor again. This cycle continues, allowing the external circulating system to provide continuous heating.

[0004] However, for the above-mentioned heat energy converter for heating, although the combustion heating chamber can be used due to the reciprocating circulation of water vapor, only a small amount of water needs to be added, the combustion heating chamber is rapidly heated after being powered, the water is vaporized, and water vapor is generated. After the water vapor enters the gas heat exchanger, the cold water in the capillary pipe is rapidly heated, and the highest water temperature that can be replaced is reached at the water outlet and enters the external circulation system; when the water vapor meets the cold water newly introduced through the water inlet, it will condense into water and drop into the combustion heating chamber, which will continue to heat under the action of the combustion heating chamber and form water vapor again. Such a reciprocating circulation allows the external circulation system to continuously provide heat, and the following relatively obvious defects still exist during use: the above-mentioned device uses water heated in the combustion heating chamber to generate high-temperature steam to heat the cold water in the heat exchange pipe, however, under the circulation of high-temperature heating, dirt and impurities are mixed in the water, if the circulating heated water is not cleaned and filtered in time, the problem of dirt and impurities condensing on the inner wall of the combustion heating chamber and the surface of the heating rod will occur.

[0024] The micro pump body 6 is connected with the water delivery pipe 7 penetrating to one side of the inside of the pure water storage and heating cavity 5 for extracting the used pure water for cleaning and filtering and adding pure water into the pure water storage and heating cavity 5, the micro pump body 6 is connected with the cleaning filter 8 for cleaning and filtering the used pure water and circulating into the inside of the pure water storage and heating cavity 5, the three-way valve 9 is like a "traffic hub" at the position of the water delivery pipe 7 close to the input end of the micro pump body 6, the adding pipe 10 connected with the upper end extends out of the outside of the upper end of the heat energy converter main body 1. When the corresponding passage is opened, the external pure water can flow in smoothly, and when the passage is switched, the internal pure water can be guided out. The micro pump body 6 and the cleaning filter 8 are arranged at the top end inside the heat exchange chamber 2 by the blocking plate, which not only avoids interfering with the heat exchange process, but also fully utilizes the space to ensure the compact operation of the cleaning and filtering process.

[0025] The three-way valve 9 is arranged at the position of the water delivery pipe 7 close to the input end of the micro pump body 6, the adding pipe 10 is arranged at the upper end of the three-way valve 9 and penetrates to the outside of the upper end of the heat energy converter main body 1 for adding pure water, the micro pump body 6 and the cleaning filter 8 are arranged at the top end inside the heat exchange chamber 2 by the blocking plate, and the three-way valve 9 is arranged at the position of the water delivery pipe 7 close to the input end of the micro pump body 6, the water flow direction can be changed by switching the valve.

[0029] The front of the pure water storage and heating cavity 5 is provided with a water level window 19 fixed outside the heat energy converter body 1, which is a "window" for the operator to observe the water level in the pure water storage and heating cavity 5.

[0031] When it is necessary to clean the pure water in the pure water storage and heating cavity 5, the three-way valve 9 located near the input end of the water conveying pipe 7 of the micro pump body 6 switches the passage, opens the internal pure water extraction channel, and the micro pump body 6 starts to extract the used pure water from the pure water storage and heating cavity 5 and convey it to the cleaning filter 8. The cleaning filter 8 is stably connected to the pipeline by using the dismounting flange 11 at both ends, filters the pure water, and removes scale, impurities and the like. The filtered pure water is reflowed to the pure water storage and heating cavity 5 through the circulating pipe 12, completes the self-cleaning cycle, maintains the cleanliness of the pure water in the cavity, and ensures the subsequent heating and heat exchange efficiency. If new pure water needs to be supplemented, the three-way valve 9 is switched to the passage connected to the filling pipe 10, and external pure water can be smoothly injected into the pure water storage and heating cavity 5,
