[0016] The storage type electric water heater using a carbon fiber light wave tube as a heat source also includes:

[0017] A magnesium rod, which is arranged on one side of the water inlet pipe;

[0018] a sewage outlet, which is arranged on one side of the water outlet;

[0019] The heat-insulating layer is arranged between the outer shell and the inner liner and is used to keep the water in the inner liner warm.

[0020] Furthermore, the control unit is provided with a heating start temperature Z1 and a heating target temperature Z2, and the temperature control probe detects the water temperature P in the inner tank in real time.

[0021] If P≤Z1, the control unit controls the carbon fiber light wave tube to heat;

[0022] If P≥Z2, the control unit controls the carbon fiber light wave tube to stop heating;

[0023] The heating start temperature Z1 is positively correlated with the heating target temperature Z2, and Z1=Z2-z is set, where z is the compensation parameter for calculating the heating start temperature;

[0024]

[0026] Furthermore, the heating power of the carbon fiber light wave tube can be adjusted.

[0027] If the water outlet pipe does not discharge water, the heating power of the carbon fiber light wave tube is determined according to the water temperature in the inner tank and the heating target temperature;

[0028] If the water outlet pipe is discharging water, the heating power of the carbon fiber light wave tube is determined according to the water temperature in the inner tank, the heating target temperature, and the water outlet and water inlet flow rates.

[0029] Furthermore, if the water outlet pipe does not discharge water, the heating power of the carbon fiber light wave tube is Q1,

[0030]

[0031] Among them, p is the heating difference evaluation parameter, a1 is the first compensation parameter of heating power, and q1 is the first basic value of heating power.

[0032] Furthermore, if the water outlet pipe is discharging water, the second water flow rate detection device detects the water flow rate B at the water outlet, the water level detection device detects the water level H in the inner tank, and the control unit is provided with a water replenishment level Hz.

[0033] If H<Hz, the control unit controls the water inlet pipe to open to replenish water to the inner tank, the first water flow rate detection device detects the water flow rate C of the water inlet pipe, and the heating power of the carbon fiber light wave tube is adjusted to Q2;

[0034] If H≥Hz, the heating power of the carbon fiber light wave tube is adjusted to Q3.

[0035] Furthermore,

[0036]

[0037] Wherein, a2 is the second compensation parameter of heating power.

[0038] Furthermore,

[0039]

[0040] Wherein, a3 is the third compensation parameter of heating power.

[0041] Furthermore, the control unit is provided with a maximum heating power Qm, and for the heating power Qi of the carbon fiber light wave tube, i=1, 2, 3,

[0042] If Qi<Qm, the control unit controls the carbon fiber light wave tube to heat at the power Qi;

[0043] If Qi≥Qm, the control unit controls the carbon fiber light wave tube to heat at a power of Qm.

[0044] Furthermore, the outer surface of the carbon fiber light wave tube is covered with a stainless steel tube.

[0045] Furthermore, the water outlet angle of the water inlet on one side of the inner tank is set horizontally.

[0046] Furthermore, the water inlet and the sewage outlet are each equipped with a solenoid valve and are respectively connected to the control unit, and the control unit can control the opening and closing of the two solenoid valves.

[0047] Furthermore, a sewage pipe with a compression function is provided in the sewage outlet.

[0048] Furthermore, the control unit is provided with a networking module capable of connecting to an external network.

[0049] Furthermore, the outer wall of the stainless steel tube is coated with Teflon material.

[0050] Furthermore, the water storage electric water heater using the carbon fiber light wave tube as a heat source further includes a display unit connected to the control unit and capable of displaying the working status of various components of the water heater.

[0051] Furthermore, the networking module can be connected to a personal mobile phone.

[0052] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention detects the water temperature in the inner tank and the water flow rate in the inlet and outlet pipes, and adjusts the heating power of the carbon fiber light wave tube, thereby ensuring the intelligence of the water heater heating. By adjusting the heating power, the accuracy of the water temperature control of the water heater is increased, and the water temperature reaches the required temperature as soon as possible while meeting the energy-saving requirements.

[0053] Furthermore, when the heating standard temperature value is large, it indicates that the demand for hot water is large. At the same time, the larger heating standard temperature value requires longer heating energy and duration. At this time, the heating start temperature calculation compensation parameter value set is large, which ensures timely heating of the water temperature and meets the demand for hot water; when the heating standard temperature value is small, it indicates that the demand for hot water is small. At the same time, the smaller heating standard temperature value requires shorter heating energy and duration. At this time, the heating start temperature calculation compensation parameter value set is small, so that the water temperature can be stable within a certain range for a long time.

[0054] Furthermore, when the water outlet pipe and the water inlet pipe are not working, the carbon fiber light wave tube only heats the water in the inner tank. At this time, only the relationship between the real-time water temperature and the heating standard temperature is considered. When the water outlet pipe and the water inlet pipe are working, it means that hot water is needed in real time. At this time, the heating power of the carbon fiber light wave tube is adjusted to ensure the timeliness of water heating.

[0055] Furthermore, when the difference between the real-time water temperature and the heating target temperature is small, a smaller power is used for heating. While meeting the temperature increase, energy consumption is appropriately reduced, thereby achieving the purpose of energy saving. At the same time, by heating with a smaller power, the time required for the temperature to reach the target is extended, the number of times the carbon fiber light wave tube is repeatedly started and stopped is reduced, and energy consumption is further reduced. When the difference between the real-time water temperature and the heating target temperature is large, the heating power of the carbon fiber light wave tube is increased, so that the water temperature rises rapidly and the temperature requirement is met as soon as possible.

[0056] Furthermore, when the water outlet pipe is discharging water but the water inlet pipe is not receiving water, it indicates that there is a demand for hot water. At this time, the heating power of the carbon fiber light wave tube is increased to quickly increase the water temperature and meet the temperature demand as soon as possible.

[0057] Furthermore, when the water outlet pipe is discharging water and the water inlet pipe is taking in water, it means that there is a demand for hot water, and the water inlet pipe replenishes external water into the inner tank. At this time, the heating power of the carbon fiber light wave tube is further increased, so that the water temperature rises rapidly to meet the temperature demand as soon as possible.

[0058] Furthermore, by setting the maximum heating power, the safety of hot water heating is guaranteed.

[0059] Furthermore, the original light wave tube's shape was redesigned, with the wires exiting from both ends now exiting from one. The diameters of the light wave tube and stainless steel tube were increased to ensure the heating wire could be wound around and had sufficient length. This also ensured the stainless steel tube had sufficient surface area for heat dissipation, lowering the surface temperature and preventing scaling. The original light wave tube was long and fixed at both ends, so it needed to be shortened and fixed at one end. This could be achieved by adding a threaded fitting at the outlet of the light wave tube to connect it to the clamp on the stainless steel tube inside the water tank, achieving single-end fixation.

[0060] Furthermore, the outer surface of the stainless steel pipe is coated with Teflon. Teflon coating combines heat resistance, chemical inertness, excellent insulation stability, and low friction. Due to its strong inertness, Teflon is almost impervious to all chemicals except for certain media, protecting parts from all types of chemical corrosion. Leveraging these properties, Teflon coating can be applied to the outer surface of stainless steel pipes in contact with water to prevent scaling.

[0061] Furthermore, a solenoid valve is installed at the water inlet and the sewage outlet of the device. The control unit can control the opening and closing of the two solenoid valves. During automatic cleaning, the solenoid valve at the water inlet is closed, and the solenoid valve at the sewage outlet is opened to drain the water inside the water heater first. Then, the solenoid valve at the water inlet is opened to flush the water tank with water. After the flushing is completed, the solenoid valve at the sewage outlet is closed, and the electric water heater can be used again after being filled with water.

[0062] Furthermore, the water outlet angle of the water inlet is designed to be nearly horizontal, allowing the horizontal injection of tap water to effectively clean scale from the bottom of the tank. The control system automatically calculates the time required to drain the tank. Once the tank is empty, the drain outlet solenoid valve remains open, while the drain valve at the water inlet opens intermittently. This pulsed water injection flushes scale from the bottom of the tank, which cannot be removed naturally, to the drain outlet, where it flows out, achieving a more thorough cleaning effect.
