Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and fig. 2, an instant electric water heater comprises an electric water heater shell 1, a heating structure, a water-passing structure, a fixed heating structure and a water-passing structure mounting structure are arranged in the electric water heater shell 1, the mounting structure comprises a heat exchanger shell 2, the heat exchanger shell 2 is fixedly mounted inside the electric water heater shell 1, the heating structure comprises heating pipes 3, a plurality of heating pipes 3 are arranged in the heat exchanger shell 2 side by side, the water-passing structure comprises a water inlet pipe 4, a water outlet pipe 5 and a middle coil pipe 6 connected with the water inlet pipe and the water outlet pipe, and the middle coil pipe 6 is wound around the periphery of the heating pipes 3. Specifically, the heating pipe 3 is a carbon fiber quartz pipe. Further, a reflecting cover 7 is further arranged in the heat exchanger shell 2, and the reflecting cover 7 covers the outer sides of the heating pipe 3 and the middle coil 6. The heating pipe is electrified to emit light, the middle coil pipe on the outer side is irradiated to generate heat, the reflecting cover on the outer side of the coil pipe recovers light energy through reflection, the coil pipe is irradiated for the second time, the light energy is fully utilized, and the light-heat conversion efficiency reaches more than 99%. The heating element is vacuum-sealed in the quartz tube, water flows in the coil tube and is heated, electricity and water are fully isolated by the quartz tube, and the safety is high.
Further, a control system structure is further arranged in the electric water heater shell 1, the control system structure comprises a hot water controller unit 8 arranged in the electric water heater shell 1, a wiring plug 9 connected with an external power supply, a display and setting unit 10 arranged on the surface of the electric water heater shell 1, an inlet temperature sensor 11 arranged at the water inlet pipe 4, an inlet flow sensor 12, an outlet temperature sensor 13 arranged at the water outlet pipe 5, an outlet flow sensor 14 and an over-temperature detection sensor 15 arranged in the middle of the electric water heater shell 1, and the hot water controller unit 8 is electrically connected with the wiring plug 9, the display and setting unit 10, the heating pipe 3, the inlet temperature sensor 11, the inlet flow sensor 12, the outlet temperature sensor 13, the outlet flow sensor 14 and the over-temperature detection sensor 15 respectively.
The working principle of the utility model is as follows: the wiring plug is connected with a power supply, the heating pipe is electrified to emit light to irradiate the middle coil pipe on the outer side to heat the middle coil pipe, the reflecting cover on the outer side of the middle coil pipe recovers light energy through reflection and irradiates the middle coil pipe for the second time, and water flowing in the middle coil pipe is heated immediately. Specifically, when a bather opens the water supply faucet, the inlet flow sensor and the outlet flow sensor sense that water flows at the inlet and the outlet, and when the flow of the inlet and the outlet is greater than 0 and the flow of the outlet is smaller than the flow of the inlet, the system sends out a water leakage alarm and simultaneously closes the power supply of the heating pipe. When the flow rates of the water inlet pipe and the water outlet pipe are larger than 0 and the same, the system supplies power to the heating pipe, the water temperature starts to rise after a few seconds, the outlet temperature sensor detects the change of the outlet temperature in real time, a change signal is transmitted to the hot water controller unit, and the power output of the power of the heating pipe is adjusted, so that the water outlet temperature is controlled. When a bather closes the water supply faucet, the inlet flow sensor and the outlet flow sensor sense that the flow speed of the inlet and outlet water flow is reduced, and the electric heating tube is cut off to supply power when the flow speed is close to 0. When the water outlet temperature does not reach the set temperature, the hot water controller unit controls the full-power operation of the electric heating pipe. When the outlet water temperature is proper, the hot water controller unit automatically reduces the power of the electric heating tube in proportion, so that the outlet water temperature is stably close to the set temperature. When the water outlet temperature reaches the set temperature, the heating power reaches the equilibrium state. When the temperature of the outlet water is lower than the set temperature, the hot water controller unit increases the power of the electric heating pipe proportionally. Thus, the hot water controller unit enables the outlet water temperature to be always stabilized at the set temperature. The over-temperature detection sensor is arranged on the heating unit shell and used for preventing dry heating. When the surface temperature of the heating body exceeds 80 ℃ when dry burning occurs, heating is automatically stopped and a fault code is displayed. When the surface temperature of the heating element exceeds 95 ℃, the dry-burning prevention protection device is quickly and automatically started and cuts off the main power supply, and the heating element can be used after being manually reset.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
