Abstract
The utility model discloses a water flow sensor for a quickly heating electric water heater, which belongs to a key component of a quickly heating electric water heater. The water flow sensor is used for measuring water flow. The water flow sensor comprises a cylindrical encloser (1) with a plurality of blade flow deflectors with certain gradient in the lower end. Water enters the lower part of the encloser of the water flow sensor from the inlet of the electric water heater, and impacts and drives a magnet wheel (2) to rotate through the flow deflectors. The magnet wheel is provided with an N-S-N-S permanent magnet. Four signals are input to the CPU chip of a microcomputer from a Hall sensor (4) when the magnet wheel rotates one cycle, thus providing signals for self-controlling the electrical heating power by the microcomputer. In this way, the quickly heating electric heater can output water at a constant temperature as the instructed temperature.
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 (general about 40 ℃) that people take a shower, all be to select one to add thermoelectric (al) power by potentiometer or many grades of power regulations, by manually adjusting inflow and heating power repeatedly, allow leaving water temperature reach about 40 ℃ then.So very inconvenient, cold day particularly, anxious more transfer more bad.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiency that prior art exists, a kind of water flow sensing unit of quick-heating type electric water heater constant temperature water outlet of novel structure to be provided.Promptly, reach the constant temperature water outlet by the instruction temperature of selecting by microcomputer-recognized intelligent control.For example you select 40 ℃ instruction temperature, open inlet valve, and the hot water that comes out is exactly 40 ℃.This process just needs a signal of measuring flow of inlet water, then according to the signals of the different outputs of inflow with regard to device inequality, provide a parameter for 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.
Above-mentioned purpose is achieved in that the water flow sensing unit of quick-heating type electric water heater, comprise and have several pieces that cylindrical drum shell of certain degree of tilt flabellum flow deflector is arranged in the lower end, there is a blind hole at the center, cylinder top that connects flow deflector, upper bracket inserts the shell top and is adhesively fixed with resin and shell, symmetry vertically has four permanent magnetism blooms on the centered cylinder of rotation magnet-wheel, pole arrangement is N-S-N-S in proper order, magnet-wheel up and down two ends cylinder respectively with flow deflector top central blind hole, upper bracket center pit clearance fit, outside the shell of magnet-wheel one side, Hall element is installed, the signal of Hall element output is connected on the cpu chip of micro computer, cylindrical shell is installed in the water inlet of quick-heating type electric water heater, cover silica gel plug in below is fixed with water intaking valve.
The water flow sensing unit of quick-heating type electric water heater is skillfully constructed, modern design, and when water flow through magnet-wheel, magnet-wheel was impacted rotation, whenever circled, and Hall element just receives four signals of N-S-N-S.Discharge is big, and the signal of Hall element output is just close; Discharge is little, and the Hall element output signal is just few, and just according to the power control electrical heating power of signal, the feasible water temperature stability that flows out from electric heater reaches the leaving water temperature of prior setting to micro computer.

Embodiment
The water flow sensing unit of quick-heating type electric water heater, comprise and have several pieces that cylindrical drum shell 1 of certain degree of tilt flabellum flow deflector is arranged in the lower end, there is a blind hole at the center, cylinder top that connects flow deflector, upper bracket 3 inserts shell 1 top and is adhesively fixed with epoxy resin and shell, symmetry vertically has four permanent magnetism blooms on the centered cylinder of rotation magnet-wheel 2, pole arrangement is N-S-N-S in proper order, magnet-wheel up and down two ends cylinder respectively with flow deflector top central blind hole, upper bracket 3 center pit clearance fit, Hall element 4 is installed in shell 1 outside in magnet-wheel one side, the signal of Hall element output is connected on the cpu chip of micro computer, cylindrical shell 1 is installed in the water inlet of quick-heating type electric water heater, cover silica gel plug in below is fixed with water intaking valve.
When using quick-heating type electric water heater, when water entered water heater from water heater below water inlet, 5 water that have certain degree of tilt flabellum flow deflector allow and enter were flushed on the magnet-wheel 2, and magnet-wheel rotates under the impact of water, whenever circle, Hall element just receives four signals of N-S-N-S.Discharge is big, and the magnet-wheel rotation is just fast, and the signal of Hall element 4 outputs is just close; Discharge is little, and the magnet-wheel rotation is just slow, and the signal of Hall element 4 outputs is just few.This just provides a parameter for micro computer calculates the electrical heating power that needs, and reaches along with inflow changes and the electrical heating power of variation, thereby has realized the purpose of automatic control leaving water temperature.
