This controlling party ratio juris of the present invention is: the discharge of immediately heating water heater as variable, is participated in automatic constant-temperature control.
The delivery port of immediately heating water heater communicates with atmosphere, and being does not have the duty of pressure, and water yield is determined by inflow.Be that inflow equals water yield, inflow, water yield general designation discharge are called for short flow.
The automatic constant-temperature control method of immediately heating water heater of the present invention, be discharge with immediately heating water heater as variable, participate in automatic constant-temperature control: when heating power is adjusted to the limit, the discharge of immediately heating water heater participates in adjusting as variable.Concretely, water temperature is lower than setting value, and---the corresponding discharge that reduces that corresponding increasing heating power is until maximum---water temperature still is lower than setting value---is until minimum; Water temperature is higher than setting value---the corresponding heating power that reduces until minimum---water temperature still is higher than setting value---corresponding increased water flow amount until maximum.
Because two variablees of heating power and discharge successively or simultaneously participate in adjusting, and make the water temperature automatic constant-temperature control range of immediately heating water heater obviously strengthen.The user behind the design temperature, opens water flow switch as required, and temperature control system just can be chosen a suitable heating power and flow, to satisfy instructions for use automatically in adjustable extent.
Implement this method the water temperature of immediately heating water heater is carried out automatic constant-temperature control, need be by means of the microcontroller technology.Also electromagnetic type or electrodynamic type to be set and other forms of electricity can be controlled the valve of the water yield, so that rapidly control instruction is made a response.During the reality regulation and control, the maximum of discharge depends on the hand control valve and the hydraulic pressure of immediately heating water heater.Discharge during the hand control valve full-gear of " corresponding increased water flow amount is until maximum " described in the inventive method and immediately heating water heater equates.The minimum discharge of valve that the electromagnetic type of " the corresponding discharge that reduces is until minimum " described in the inventive method and immediately heating water heater setting or electrodynamic type and other forms of electricity can be controlled the water yield equates.
The control starting stage of work of the present invention, it is maximum that heating power is tending towards, and the valve discharge that electricity can be controlled the water yield is in maximum; Read desired temperature then, the adjustment heating power enters in the program of control method setting of the present invention.
Advantage of the present invention is to enlarge the temperature control adjusting range, improves accuracy of temperature control, makes the leaving water temperature of immediately heating water heater more approach setting value, helps reducing energy resource consumption.
