Embodiment one
Fig. 1 is the schematic illustration of one water heater of the utility model embodiment, as shown in Figure 1, the water heater includes: control
Component 11, inlet valve 12, flow of inlet water measuring part 13, inlet water temperature measuring part 14, heating element 18 and water inlet processed；
The working principle of the water heater are as follows: the control unit 11 is measured according to the flow of inlet water measuring part 13
The inlet water temperature and preset output water temperature that flow of inlet water, the inlet water temperature measuring part 14 are measured, determine current inflow
Heating load needed for being heated to be the preset output water temperature, and current according to the heating load and the heating element
Heating power controls the inlet valve 12 and adjusts current flow of inlet water.In this way, water heater can be adjusted according to the heating load
Flow of inlet water, it is ensured that preset output water temperature reaches.
In the present embodiment, the inlet valve 12, which adjusts current flow of inlet water, to be realized by adjusting the working condition of itself
, the working condition of the inlet valve 12 includes two kinds: one is normal discharge states, or are big water state, and another kind is
Small flow status, or be small water state, the working condition of the inlet valve 12 is by solenoid valve control.
As a kind of implementation, the water heater further includes output water temperature measuring part 15, the output water temperature measurement
Component 15 is electrically connected the control unit 11, and the output water temperature measuring part 15 is after the heating element heats preset time
Output water temperature is measured, and the output water temperature is sent to the control unit 11；The control unit is according to the water outlet water
