Abstract
The utility model relates to a water flow sensor of a fast heating electric water heater, which belongs to a critical component of an electric water heater and is used for measuring water flow. The water flow sensor comprises a cylinder valve body with the upper end and the lower end respectively equipped with a water inlet and a water outlet, wherein a water flow rotor assembly and a Hall elementare arranged inside the valve body, the water flow rotor assembly includes a turbine switch housing, a magnetic rotor and a brake ring; and fixing seats for fixedly installing the water flow sensor are disposed on the left side and the right side of the valve body. When passing through the turbine switch housing, water flow propels the magnetic rotor to rotate; when different magnetic poles closeto the Hall element, the Hall element is turned on, and when different magnetic poles move away from the Hall element, the Hall element is turned off, accordingly rotating speed of the rotor is measured. Being cut by magnetic field of permanent magnet materials, water turns into magnetized water, accordingly oxygen content in the water is increased, and the water enables people to feel fresh after bathing. Additionally, the brake ring is used for stopping the magnetic rotor in high speed rotation from rotating and ending pulse signal output; a controller can cut off power supply to prevent dry combustion if the controller can not receive pulse signals.
Description
Technical field
The utility model relates to a kind of water flow sensing unit of quick-heating type electric water heater, belongs to the critical component of quick-heating type electric water heater, is used to measure the device of discharge.
Background technology
Quick-heating type electric water heater in the market in use, need to select to be fit to the water temperature (generally being about 40 ℃) that people take a shower, generally all be by potentiometer or keep off power regulation more and select to add a thermoelectric (al) power, by manually adjusting inflow and heating power repeatedly, allow leaving water temperature reach about 40 ℃ then.So very inconvenient, winter particularly, anxious more transfer more bad.In addition, also there are some electric heaters to design not enough science, the dry combustion method phenomenon takes place sometimes.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of water flow sensing unit of quick-heating type electric water heater of novel structure in order to solve the deficiency that prior art exists.Promptly, reach the constant temperature water outlet by the instruction temperature of selecting, and can prevent dry combustion method by controller (micro computer) Based Intelligent Control.If you select 42 ℃ instruction temperature, open water intaking valve, the hot water that comes out is exactly 42 ℃.This process just needs a signal of measuring flow of inlet water, also inequality according to the signal of the different outputs of inflow then, provide a parameter for controller (micro computer) calculates electrical heating power, reached, realized the automatic constant temperature water outlet along with inflow changes and the electrical heating power of variation.
The technical solution of the utility model is as follows: a kind of water flow sensing unit of quick-heating type electric water heater, be included in upper and lower end and be respectively equipped with the cylindrical drum valve body of water delivering orifice and water inlet, described valve inner is provided with current rotor assembly and Hall element, and described current rotor assembly is made up of turbine switch housing, magnet rotor and brake hoop.
The left and right sides of described valve body is provided with and is used for fixing the holder that this water flow sensing unit is installed.
All sides of described valve body are provided with at least two screws that are used for fixing described current rotor assembly of assembling and Hall element.
The beneficial effects of the utility model are: 1, long service life
Be difficult for aging
Safe and reliable etc.; 2, there is water to flow through pulse signal output is just arranged
Be contained in and do not have the dry combustion method phenomenon on the water heater; 3, simple in structure, characteristics such as reliability is high, measurement range is wide.

Among the figure: 1, valve body 2, current rotor assembly 3, Hall element 4, water inlet 5, water delivering orifice 6, holder 7, screw 21, turbine switch housing 22, magnet rotor
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment:
Shown in Fig. 1-5, the utility model comprises and is included in the cylindrical drum valve body 1 that upper and lower end is respectively equipped with water delivering orifice 5 and water inlet 4, described valve body 1 inside is provided with current rotor assembly 2 and Hall element 3, and described current rotor assembly 2 is made up of turbine switch housing 21, magnet rotor 22 and brake hoop (not marking among the figure).Be provided with in the left and right sides of valve body and be used for fixing the holder 6 that this water flow sensing unit is installed.All sides of described valve body 1 are provided with at least two screws 7 that are used for fixing described current rotor assembly 2 of assembling and Hall element 3.
When current by turbine switch housing 21, promote magnet rotor 22 rotations, different magnetic poles is Hall element 3 conductings during near Hall element 3, Hall element 3 disconnects when leaving.Thus, can measure rotor speed.According to the curve of discharge, rotor speed and the output signal (voltage) of surveying, just can determine the startup hydraulic pressure of water heater, and the startup rotating speed that starts corresponding startup discharge of hydraulic pressure and rotor.By control circuit, just can realize when rotor speed water heater startup work when starting rotating speed; When starting rotating speed, water heater quits work at rotating speed.Water heater startup hydraulic pressure generally is set in 0.01MPa like this, and startup discharge is 3～5L/min (need satisfy the restriction of water heater standard to maximum temperaturerise).In addition, because water under the permanent magnetic material magnetic field intercepts, becomes magnetized water, the oxygen level in the water increases, and makes people's bathing after sensation salubrious.The effect of brake hoop is when cutting off the water, and prevents the magnet rotor 22 of high speed rotating to rotate the output of stopping pulse signal.Controller does not receive pulse signal, cuts off the electricity supply, and prevents dry combustion method.
