Description

Technical Field

[0002] Heating refers to obtaining an appropriate temperature inside a building through the design and installation of the building and the cold-proof heating device. Generally, heating equipment uses preheated fluid to continuously flow through the radiator (heat sink). This fluid is usually steam or hot water, called the heat-carrying medium or heat medium. After the heat medium is heated by a heat generation, heat collection or heat exchange device (heat source) located outside the space, it is distributed to each heating radiator through the heating pipeline. After the heat medium transfers a part of the heat carried to the radiator, it flows back to the heat source through the return pipeline, is reheated, and circulates continuously, so that heat can be continuously transferred to the heated space.

[0003] When using the energy-saving and environment-friendly variable-frequency electric heating equipment, it is necessary to heat water from a low temperature to a high temperature. However, in the existing technology, during the process of heating water with the heating element of the electric heating furnace, due to the low temperature of the water, a large amount of time is required for heating during the heating process, which affects the heating progress, resulting in low heating efficiency and waste of time, thus failing to achieve the energy-saving and environment-friendly effect. Content of the Utility Model

[0004] This application provides an energy-saving and environment-friendly variable-frequency electric heating equipment to solve the problem proposed in the above background technique that during the process of heating water with the heating element of the electric heating furnace, due to the low temperature of the water, a large amount of time is required for heating during the heating process, which affects the heating progress, resulting in low heating efficiency and waste of time.

[0005] This application provides an energy-saving and environment-friendly variable-frequency electric heating equipment, including a heat storage tank. A liquid storage tank is arranged inside the heat storage tank. One side of the upper end of the liquid storage tank is provided with a water outlet pipe, and the other end of the liquid storage tank is provided with a water inlet pipe. The other end of the water inlet pipe is arranged at the corresponding position of the water outlet pipe; a threaded heating pipe is embedded and installed inside the liquid storage tank; one end of the liquid storage tank penetrates through the heat storage tank and is provided with a water valve, and the other end of the liquid storage tank penetrates through the heat storage tank and is provided with a bearing. A rotating shaft is arranged through the bearing. A driving motor is arranged outside the heat storage tank at the position of the rotating shaft; a stirring net is sleeved outside the rotating shaft inside the liquid storage tank.

[0006] Preferably, heat-insulating stone columns are arranged on the inner wall of the liquid storage tank, and multiple heat-insulating stones are arranged around the inner wall.

[0007] Preferably, a control valve is arranged at the upper end of the water outlet pipe, and a heat dissipation pipe is arranged at the upper end of the control valve.

[0008] The outer ring of the heat dissipation pipe is sleeved with a heating wire, and the outer ring of the heating wire is provided with a protective shell.

[0009] Preferably, the inner wall of the heat storage tank is provided with a heat-insulating layer, and part of the heat-insulating layer is located on the outer wall of the liquid storage tank.

[0010] Preferably, a machine box is arranged on the upper end of the heat storage box, and numerous heat dissipation holes are evenly opened on the side wall of the machine box.

[0011] Preferably, a variable frequency motor is arranged at the bottom of the chassis, and four variable frequency motors are arranged linearly.

[0012] Preferably, a rotating shaft is disposed at the upper end of each of the four variable frequency motors, and a fan is disposed at the upper end of the rotating shaft.

[0013] Preferably, a heat sink is provided at the upper end of the chassis, and a heat sink is provided at the bottom of the heat sink.

[0014] Preferably, a baffle is provided on the top of the heat dissipation box, and a swinging fan is provided at the lower end of the baffle.

[0015] Beneficial effects:

[0016] Considering that when using energy-saving and environmentally friendly variable frequency electric heating equipment, it is necessary to heat water from low temperature to high temperature. However, in the existing technology, when using the heating body of the electric heating furnace to heat the water, due to the low temperature of the water, a lot of time is required to heat it during the heating process, which affects the heating progress, resulting in low heating efficiency and time waste.

[0017] The present application controls the water valve to add the required water into the liquid storage tank, then connects the external power supply, starts the threaded heating tube to heat the water in the liquid storage tank, and starts the driving motor at the same time. When the driving motor is turned on, the rotating shaft begins to rotate. Since a stirring net is installed on the outer ring of the rotating shaft, the stirring net will rotate with the rotating shaft to stir the water in the liquid storage tank so that the water in the liquid storage tank is heated evenly. At the same time, the water in the liquid storage tank flows into the heat dissipation tube in the heat dissipation box through the water outlet pipe under the action of the control valve, and returns to the liquid storage tank from the water inlet pipe for reheating, and repeats and circulates continuously to maintain heating.

[0018] In addition, insulation stone columns are set inside the liquid storage tank. The insulation stone columns have the characteristics of fast heat absorption and slow heat dissipation, which can avoid heat loss during the operation of the device without starting it. This not only achieves the heating purpose by heating the heat storage liquid, but also reuses and stores the waste heat after heating, thereby greatly reducing the heating cost.

[0040] Among them, the heat preservation stone columns 8 have the characteristics of fast heat absorption and slow heat dissipation, so that the temperature inside the liquid storage tank 3 can be kept from easily flowing away.

[0041] A control valve 25 is arranged at the upper end of the water outlet pipe 11, and a heat dissipation pipe 13 is arranged at the upper end of the control valve 25.

[0042] Among them, the control valve 25 can control the water output of the water outlet pipe 11.

[0043] A heating wire 15 is sleeved and installed outside the heat dissipation pipe 13, and a protective shell 14 is arranged outside the heating wire 15.

[0044] Among them, the heating wire 15 can heat the heat dissipation pipe 13, thereby increasing the temperature of the heat storage liquid inside the heat dissipation pipe 13.

[0045] The inner wall of the heat storage tank 1 is provided with a heat insulation layer 2, and a part of the heat insulation layer 2 is located on the outer wall of the liquid storage tank 3.

[0046] Among them, the heat insulation layer 2 can reduce the heat loss of the heat storage liquid inside the liquid storage tank 3

[0047] A chassis 16 is arranged at the upper end of the heat storage tank 1, and countless heat dissipation holes 17 are evenly opened on the side wall of the chassis 16.

[0048] Among them, the heat dissipation holes 17 can timely discharge the heat generated when the variable frequency motor 18 works.

[0049] A variable frequency motor 18 is arranged at the bottom inside the chassis 16, and four variable frequency motors 18 are linearly arranged.

[0050] Among them, the variable frequency motor 18 is to provide power for the rotating shaft 19 and can also automatically change the size of the blowing and the length of the blowing time.

[0051] Rotating shafts 19 are arranged at the upper ends of the four variable frequency motors 18, and a fan 20 is arranged at the upper end of the rotating shaft 19.

[0052] Among them, the rotation of the fan 20 can generate an air flow to blow out the hot air above.

[0053] A heat dissipation box 21 is arranged at the upper end of the chassis 16, and a heat dissipation plate 22 is arranged at the bottom of the heat dissipation box 21.

[0054] Among them, the heat dissipation plate 22 can prevent things from falling onto the fan 20 and causing damage to the fan 20.

[0056] Among them, the swing air blade 24 can adjust the angle, so that the blown air will blow in different directions.

[0057] Working principle: When this energy-saving and environment-friendly variable frequency electric heating device is in use, the user adds the required water into the liquid storage tank 3 by controlling the water valve 10. At this time, the external power supply is connected, and the threaded heating pipe 7 is started to heat the water in the liquid storage tank 3. At the same time, the driving motor 4 is started. When the driving motor 4 is turned on, the rotating shaft 6 starts to rotate. Since the stirring net 9 is installed outside the rotating shaft 6, the stirring net 9 will rotate together with the rotating shaft 6 to stir the water in the liquid storage tank 3 so that the water in the liquid storage tank 3 is heated evenly.

[0058] Meanwhile, the water in the liquid storage tank 3 flows into the heat dissipation pipes 13 in the heat dissipation box 21 through the water outlet pipe 11 under the action of the control valve 25. At the same time, the variable frequency motor 18 can be started. After the variable frequency motor 18 is started, it will drive the rotating shaft 19 and the fan 20 to rotate. At this time, the heating wire 15 outside the heat dissipation pipe 13 also starts to work, continuously heating the heat storage liquid. Together with the fan 20, the generated hot air can be diffused out of the baffle 23 through the upper swing blades 24. At this time, the heat storage liquid bypasses the heat dissipation pipe 13 and returns to the liquid storage tank 3 through the water inlet pipe 12 to be reheated. This process repeats and circulates continuously to maintain heating.

[0059] The variable frequency motor 18 can not only automatically change the blowing size and blowing time length, but also control the blowing angle by controlling the swing blades 24. At the same time, heat preservation stone columns 8 are arranged inside the liquid storage tank 3. The heat preservation stone columns 8 have the characteristics of fast heat absorption and slow heat dissipation, which can avoid heat loss during the process of not starting the device operation, achieve maximum power saving, and obtain good energy-saving effects.

[0060] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
