Description

The hot thermostatic electric water heater of a kind of speed
Technical field
The utility model relates to electric heater, especially a kind of quick-heating electric water heater of good constant-temperature effect.
Background technology
Quick-heating electric water heater is a kind of electric heater that does not need the thermal storage water tank, after opening the water inlet pipe that connects heating inner liner, and just can be from connecting the outlet pipe output hot water of heating inner liner.Its small volume, flexible for installation, but because the power of electric heating tube is higher, the control difficulty of its outlet pipe leaving water temperature is larger.
In order to improve the control accuracy of quick-heating electric water heater leaving water temperature, existing part quick-heating electric water heater adopts controllable silicon to regulate the heating power of electric heating tube with the adjusting water outlet temperature on the market at present, but controllable silicon in use can produce larger heat, usually need to be on controllable silicon installation of heat radiator, so both improved the manufacturing cost of quick-heating electric water heater, also improved energy consumption, when electric heater service time is longer, controllable silicon works long hours in higher temperature, also can reduction of service life; On the other hand, existing most of quick-heating electric water heaters are mounting temperature sensor on outlet pipe just, variations in temperature detected by temperature sensor signal is passed to control circuit board, control circuit board is again by the heating power of thyristor regulating electricity-saving heating pipe, yet when variation in water pressure is larger, flow of inlet water changes also greatly, and this control mode relatively lags behind, and can reduce because of variation in water pressure the control accuracy of leaving water temperature.
The utility model content
The technical problems to be solved in the utility model is to provide the hot thermostatic electric water heater of a kind of speed, good constant-temperature effect, and long service life, manufacturing cost is lower.
For achieving the above object, the technical solution of the utility model is: the hot thermostatic electric water heater of a kind of speed, comprise inner bag, the water inlet pipe and the outlet pipe that connect inner bag, control circuit board, electric heating tube is housed in inner bag, the controllable silicon of controlling electric heater for heating power is housed on control circuit board, controllable silicon is fitted on the outer wall of water inlet pipe, temperature sensor is housed on outlet pipe, flow sensor is housed on water inlet pipe, temperature sensor is connected control circuit board with flow sensor by holding wire, control the leaving water temperature of outlet pipe after the parameter of control circuit board C.T sensor and flow sensor transmission by the heating power of SCR control electric heating tube.
Further improve, the magnetic valve of controlling water inlet pipe current break-make is housed on described water inlet pipe.Magnetic valve also can pass through wire connecting valve and control circuit board, by switch, matches and conveniently uses electric heater.
Further improve, the flow valve of regulating the water inlet pipe flow of inlet water is housed on described water inlet pipe.Preferred described flow valve is manual flow valve.Thereby the convenient flow of inlet water of regulating water inlet pipe is controlled the water flow of outlet pipe.
Further improve, overheat switch also is housed on described electric heating tube.Can prevent electric heating tube dry combustion method and overheated, extend the service life of electric heating tube.
The utility model is due to temperature sensor being housed on outlet pipe, flow sensor is housed on water inlet pipe, and control circuit board is controlled the leaving water temperature of outlet pipe by the parameter of temperature sensor and flow sensor transmission by the heating power of SCR control electric heating tube; Considered that leaving water temperature changes and variation in water pressure causes that flow of inlet water changes these two principal elements and then regulates the heating power of electric heating tube by controllable silicon, the control accuracy of heating tube heating power is high, therefore the control accuracy of its leaving water temperature is just higher, good constant-temperature effect.
On the other hand, because controllable silicon is fitted on the outer wall of water inlet pipe, by the current of water inlet pipe, take away the heat that controllable silicon produces, the assurance controllable silicon can be worked at lower temperature, has extended service life; The corresponding heat that reduces the heating tube generation of the heat that the current of water inlet pipe are taken away, reduce energy consumption to greatest extent, and because saving radiator for thyristors, its manufacturing cost is lower simultaneously.
The accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model structure cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in further detail.
Shown in Fig. 1, Fig. 2, the hot thermostatic electric water heater of a kind of speed, comprise inner bag 1, the water inlet pipe 2 that connects inner bag 1 and outlet pipe 3, control circuit board 4, electric heating tube 5 is housed in inner bag 4, the controllable silicon 6 of controlling electric heating tube 5 heating powers is housed on control circuit board 4, controllable silicon 6 is fitted on the outer wall of water inlet pipe 2, and described controllable silicon 6 can have a plurality of;
Temperature sensor 7 is housed on outlet pipe 3, flow sensor 8 is housed on water inlet pipe 2, temperature sensor 7 is connected control circuit board 4 with flow sensor 8 by holding wire, and the heating power of controlling electric heating tube 5 by controllable silicon 6 after the parameter of control circuit board 4 C.T sensors 7 and flow sensor 8 transmission is controlled the leaving water temperature of outlet pipe 3.
The magnetic valve 9 of controlling water inlet pipe 2 current break-makes is housed on described water inlet pipe 2, and magnetic valve 9 can connect gauge tap and control circuit board 4 by wire.
The flow valve 10 of regulating water inlet pipe 2 flow of inlet water also is housed on described water inlet pipe 2; Described flow valve 10 can be selected manual flow valve.
For preventing electric heating tube 5 dry combustion methods and overheated, overheat switch 11 can be installed on electric heating tube 5.
