Description

Water storage water heater and its control system

technical field

The invention relates to the technical field of electric water heaters, in particular to a storage water heater and a control system thereof.

Background technique

In traditional water storage water heaters, electric heating tubes are used to heat the water in the water storage tank, and the latent heat of energy stored in the large water storage capacity is used. When the user starts to use the water storage tank for bathing, the outflowing hot water will fill the space with the inflowing room temperature water. For example, the temperature of room temperature water is 20°C, which will lower the temperature of the water in the storage tank. The thermostat Operate and restart the electric heating tube, when the heat flow rate is faster than the heating rate, the water heater can only maintain the bath water temperature (eg 40°C) for a specific time, eg 20 minutes.

In addition, in the existing water storage type water heater, when the water temperature in the furnace reaches a default temperature, the built-in thermostat of the water heater will turn off the heating device, and when the user turns on the faucet of the water heater, the hot water in the furnace will be discharged . Such as a lotus head shower, while cold or room temperature water flows into the water heater to fill the space created by the hot water flowing out of the water heater. The liquid flow is calculated in liters per minute. Assuming that the hydraulic pressure in the water heater is roughly constant, the outflow of hot water is equivalent to the inflow of frozen water. When the frozen water flows into the water heater, the flow rate increases, and the average temperature in the water heater drops rapidly, causing the outlet water temperature of the water heater to be too low to be used.

In summary, the structure of the existing water storage water heater obviously has inconvenience and defects in actual use, so it is necessary to improve it.
