Abstract
The utility model belongs to the technical field of household electrical appliances, in particular to a full-automatic constant temperature type electric heater, which comprises a casing and a control circuit, wherein the control circuit is arranged in the casing, a heating inner cavity is installed in the casing, the heating inner cavity is communicated with a water inlet pipe and a water outlet pipe through pipes, the heating inner cavity is electrically connected with a power supply, and a temperature detecting sensor or and a water flow regulating valve is arranged on the water inlet pipe or and the water outlet pipe. The full-automatic constant temperature type electric heater of the utility model solves the problem of negative affects to the electric heater generated by the water flow and the input voltage.
Description
Technical field
The utility model belongs to electric water-heating apparatus manufacturing technology field, particularly a kind of fully-automatic thermostatic formula electric heater.
Background technology
At present, Instant heating type or quick-heating type electric water heater is a kind of widely used shower, it controls discharge by an external current control handle, when electric heater is opened and the inner bag of current process electric heater is arranged, electric heater is by powerful rapid heat effect, make the rapid heating of cold water that enters the heating inner bag, flow out from delivery port then, for the usefulness of shower.Its control mode is to make electric heater be in a fixing power (the just common Instant heating type gear that we see is regulated) by control circuit.But, make existing electric heater be subjected to the influence of discharge bigger like this, variations in temperature is bigger, when arbitrary value of discharge and input voltage changes, will change its leaving water temperature, thereby reduce the comfort level of taking a shower, injure the bather when serious, influenced user's normal use.
Summary of the invention
The utility model discloses a kind of fully-automatic thermostatic formula electric heater, it has solved the problem that can not regulate when one of discharge and voltage change.
Technical solution adopted in the utility model is as follows: a kind of fully-automatic thermostatic formula electric heater, comprise housing and control circuit, control circuit is placed in the housing, the heating inner bag is installed in the housing, the heating inner bag is communicated with water inlet pipe and outlet pipe by pipe, heating inner bag and power supply electrically connect, and water inlet pipe is or/and be provided with temperature detection sensor on the outlet pipe or/and flow control valve.
Described electric heater, flow control valve is by Electric Machine Control.
Described electric heater, water inlet pipe is or/and establish flow sensor on the outlet pipe.
Described electric heater, the heating inner bag connects temperature controller.
Electric heater of the present utility model is different from traditional Instant heating type or quick-heating type electric water heater, its at the water inlet of electric heater or/and delivery port has been set up flow control valve, control discharge effectively by control circuit, as, the switch of current and the size of discharge; In addition, or/and delivery port is set up flow sensor, can react actual discharge at water inlet by control circuit by electric heater.
Electric heater of the present utility model is established the operation interface of display parameters on housing, by preset temperature of this operation interface input, control circuit is regulated power automatically according to the preset value of input, thereby makes leaving water temperature reach the temperature of user's input; At current value of operation interface input, control circuit is controlled flow control valve according to the automatic governor motor of preset value (small machine) of input, and discharge and input value are matched.
Description of drawings

Fig. 2 is an internal structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1-2, housing is fastened with loam cake 22 by casing 1 and forms, water inlet pipe 6 passes housing and enters inside, establish inflow temperature detecting sensor 12 and flow control valve 9 on the water inlet pipe 6, flow control valve 9 links to each other with motor 8, motor 8 is by control circuit 2 controls, and control circuit 2 is by transformer 4 power supplies, and control circuit is a custom circuit.
Heating inner bag 3 is communicated with outlet pipe 5 by inner bag outlet pipe 16, and leaving water temperature detecting sensor 13 is installed on the outlet pipe 5.
Surface of shell is provided with viewing area 18, and the user can understand electric heater state of living in.Surface of shell also is provided with "+" key 19, "-" key 21 and " switch/pattern " button 20, by "+", "-" key the temperature or the discharge of electric heater are preset, " switch/pattern " button can be used as the adjustment key of start back pattern or function again both as the function key of switching on and shutting down.
The basic functional principle of the utility model electric heater:
1, cold water enters from the water heater water inlet, and control circuit is by the numerical value/instruction control rotating speed of motor to parameter preset, by the control of motor being controlled the discharge of water inlet and the on off state of current.
2, the user only needs discharge and the temperature by operation interface input needs, and control circuit is just effectively finished the comparison of input parameter according to the numerical value of input, make water outlet meet the input requirement, and it is more comfortable to take a shower.
3, control circuit has power bar show state, and the power the when user can see control circuit work intuitively can be seen the variation of power, also can know the roughly numerical value of power.
4, control circuit has the demonstration of leaving water temperature and preset temperature, and the user can be by to the comparison of leaving water temperature and own preset temperature, so that prevent that scald or water outlet are cold excessively.
5, control circuit has the demonstration of water flow and the demonstration of preset flow, and the user can observe the variation of water flow.
6, control circuit has various fault alarms and fault self-checking function, can provide more intuitive safety and property abnormality relatively for the user.
7, electric heater has default total powerful function, can make amendment to the maximum service rating of electric heater by the default mode of button.
8, this electric heater is controlled the operating power of electric heater by adopting the self-regulating function of controllable silicon, reaches the purpose of control leaving water temperature.
9, when electric leakage takes place electric heater, the electric current that produces below 20 milliamperes just can disconnect the control circuit power supply.
The utility model is not limited to the foregoing description.Water inlet pipe only is provided with temperature detection sensor or flow control valve; Outlet pipe only is provided with temperature detection sensor or flow control valve; Outlet pipe is provided with temperature detection sensor and flow control valve simultaneously; Water inlet pipe is provided with temperature detection sensor, and outlet pipe is provided with flow control valve; Water inlet pipe is provided with flow control valve, and outlet pipe is provided with temperature detection sensor, or the like, all be protection domain of the present utility model.
