Problems solved by technology
[0005] However, it is found in the application that the continuous heating of the electric heater will lead to the stability of the fluid in the internal electric heating device, that is, the fluid is not flowing or has little fluidity, or the flow rate is stable, resulting in a greatly weakened vibration performance of the coil, which affects The descaling of the coil and the efficiency of heating, the inventor has conducted research on this, and developed a new water heater that can generate periodic or vibration according to temperature and pressure, and has applied for a patent
[0006] However, in practice, it is found that by adjusting the vibration of the tube bundle through fixed periodic changes or according to temperature and pressure, there will be hysteresis and the period will be too long or too short

Embodiment Construction
[0030] A water heater. The water heater includes an electric heating device 10 and a water tank 11 . The electric heating device 10 is arranged in the water tank 11 . The water tank 11 includes a water inlet pipe 5 and a hot water outlet 6 .
[0031] Preferably, the water tank is a cylindrical structure.
[0032] figure 1 A top view of the electric heating device 10 is shown, as figure 1 As shown, the electric heating device 10 includes a first tube box 2, a second tube box 8 and a coil 1, and the coil 1 communicates with the first tube box 2 and the second tube box 8, and the fluid in the first tube box 2 and the second tube box 8 and the coil 1 are in a closed cycle, and electric heaters 131 and 132 are arranged in the electric heating device 10, and the electric heater 13 is used to heat the inner fluid of the electric heating device 10, and then passes through The heated fluid heats the water in the tank.
[0033] Such as figure 1 -2, the first electric heater 131 a...

The present invention provides a water heater which alternately heats according to the pressure difference. The water heater comprises an electric heating device and a water tank. A first pressure sensor and a second pressure sensor are respectively arranged in the first tube box and the second tube box for detecting the first The pressure in the first pipe box and the second pipe box, the first pressure sensor and the second pressure sensor are connected to the controller for data, and the controller extracts the measured pressure data of the first pressure sensor or the second pressure sensor according to the time sequence, and passes the corresponding Comparing the pressure data of adjacent time periods to obtain the accumulation of the pressure difference or the change of the pressure difference. When it is lower than the threshold value, the controller controls the first electric heater and the second electric heater to alternately heat. The water heater of the present invention judges the steady state of the fluid according to the pressure difference or the accumulation of pressure difference changes, so that the result is more accurate, and the problem of error increase caused by aging caused by the running time problem will not be avoided.
Description
technical field [0001] The invention relates to a hot water generating device, in particular to an intermittent vibration descaling water heater. Background technique [0002] The water heater is an indispensable household appliance in current family life. And generally adopt electric water heater at present, utilize electric water heater to heat. In the applicant's previous application, a new type of coil-type electric heating coil was developed and researched, such as CN106123306A, so that the elastic tube bundle caused by the expansion of the fluid caused by heating caused heating and descaling Effect. [0003] However, in the application, it is found that the continuous heating of the electric heater will lead to the stability of the fluid in the internal electric heating device, that is, the fluid is not flowing or has little fluidity, or the flow rate is stable, resulting in a greatly weakened vibration performance of the coil, which affects Coil descaling and heati...
