Description

Method and system for detecting hot water volume in inner tank of electric water heater

technical field

The invention relates to the technical field of water heaters, and more specifically relates to a method and system for detecting the hot water volume of an inner tank of an electric water heater.

Background technique

The existing technology is to judge the hot water volume of the electric water heater by the water temperature of the inner tank. The inner tank of the electric water heater is always in a state of full water. The water gradually becomes colder. Since the temperature probe is installed in the middle and lower part of the inner tank, the water below the inner tank will gradually become cold during the process of cold water entering, which will cause the temperature measured by the temperature probe to be low, so that the displayed hot water volume is low, but the actual heat The water volume is much higher, which misleads the user and is not conducive to a comfortable bathing effect.

Contents of the invention

The purpose of the present invention is to solve the deficiencies of the prior art and provide a method that is not only reasonable in design, but also allows users to control their own bathing time according to the hot water volume information in real time, so that the bathing process is safe and comfortable to detect the inside of the electric water heater. The method of gallbladder heat.

detailed description

The technical solution will be described in detail below in conjunction with specific embodiments.

As shown in Figure 1, the present invention is a method for detecting the amount of hot water in the inner tank of an electric water heater. It is to install a water flow sensor 2 on the water inlet component or the water outlet component of the inner tank 1 of the water heater, and calculate the water flow rate by the control system 3. By multiplying the water flow by the time, the actual water flow flowing into the inner tank of the electric water heater is calculated, and then converted by the formula to obtain the remaining hot water volume of the inner tank, and the display screen 4 is controlled to display the remaining hot water volume, so that the user Enjoy accurate hot water volume reminder service. During the user's bathing process, when the amount of hot water decreases and the amount of cold water increases, the conversion formula for the remaining hot water in the inner tank is: subtract the output hot water or the incoming cold water L1 from the total hot water, which is the inner tank The remaining hot water volume L2; the total hot water volume is the capacity of the inner tank × hot water output rate. For example, the capacity of the inner tank is 80L, the output rate of hot water is 70%, and the amount of cold water entering is calculated as 20L, then the remaining amount of hot water L2 is 80×70%-20=36L, and then the remaining amount of hot water L2 will be passed through the control system Analyzed and processed, displayed on the display. In the case of heating by the electric heater of the electric water heater, there is no water flow through the water inlet pipe and the water outlet pipe, and the water volume in the inner tank reaches the maximum. At this time, the water flow sensor is in a dormant state with low power consumption, and the water flow is not detected at this time. Signal.

The output terminal of the control system is connected to the display screen, including a power module, a single-chip microcomputer and its peripheral circuits, a relay module, and a main control board. show.

Further, the water flow sensor includes a shell and a guide tube, a magnetic rotor, and a Hall element arranged inside the shell, the magnetic rotor is arranged in the guide tube, the Hall element corresponds to the magnetic rotor, and communicates with the control system through a communication module Connection; when the user uses hot water, the flowing water drives the magnetic rotor in the guide tube to rotate, and the Hall element outputs high and low levels to the control system. The control system calculates the size of the water flow through the formula, and multiplies the water flow by the time. The actual water flow flowing into the inner tank of the electric water heater can be calculated, and then the remaining hot water volume of the inner tank can be obtained through formula conversion, and the display screen can be controlled to display the remaining hot water volume.

Furthermore, the display screen is usually installed on the body of the electric water heater, or independently installed in the bathroom, and is used to display information such as the remaining hot water volume and temperature of the inner tank.

The water flow sensor can be installed in the water inlet pipe of the electric water heater. Since the water flowing into the water inlet pipe is close to the room temperature, it avoids the damage of high-temperature hot water to the key materials in the water flow sensor, and makes the water flow signal detected by the water flow sensor more accurate. In the case of heating by the electric heater, there is no water flow through the water inlet pipe and the water outlet pipe, and the water volume in the inner tank reaches the maximum. At this time, the water flow sensor is in a dormant state with low power consumption, and no water flow signal is detected at this time.
