The utility model aims at the innovative design of a high-efficiency low-power electric water heater which integrates electrical leakage protection, water break alarm, oxygen lack radio alarm, water temperature digital display, electronic control, automatic cleanness of the dirt on a heating element, etc. into a whole to solve the problem of time saving and convenience for people to use hot water.

Description

High-effect, low-power electric heater

The utility model relates to a kind of high-effect, low-power electric heater, belongs to the efficient energy-saving electrothermal hydrophone.

Various in style, the dog-eat-dog of existing water heater, great majority are in style design aspect renovation, and function ratio is more single, and especially water temperature is low during bathing water, and flow is little etc., and the aspect fails to solve, and has restricted development to a great extent.

The purpose of this utility model is at a kind of high-effect, low-power electric heater of innovative design; collection earth leakage protective, warnings of cutting off the water, anoxic radio alarming, the digital demonstration of water temperature, electrical adjustment, clean dirt on the heater etc. automatically and be one, with the solution people with the difficult problem that it is convenient that hot water saves time.

The utility model purpose, be to be achieved through the following technical solutions: when starting water inlet, press starting switch AN1, because emergency stop switch AN2, hydraulic pressure switch K1, the normally closed point of earth leakage protective relay J 5-2 are serially connected on the AN1, connect 2 pin of IC1 simultaneously, become high level by inner 8 pin that amplify of IC1, J1 gets through triode V1 amplifying relay, the closed self-locking AN1 of J1-2, the closed LED1 light emitting diode of J1-3 is bright, the closed heater RL1 of J1-1, magnetic valve G1, high-pressure pump P1 work; When the hot water of the big flow of needs, open W1 firepower by-pass cock K2 closure, 4 pin of IC1 become low level, become high level by inner 10 pin that amplify of IC1, bright through the closed LED3 light emitting diode of triode V2 amplifying relay J2-2, the closed heater RL2 of J2-1 under fire regulation W1 regulates, work (adjustment); Simultaneously digital displays temperature, demonstration time, adjust AN3 (liter), AN4 (temperature, time conversion), AN5 (falling); When the T1 temperature reached setting value, 15 pin of IC1 became high level, disconnect through triode V3 amplifying relay J3-1; J3-1 auto-closing when in like manner, temperature descends; This electric heater heater is produced on the gear heat-radiating structure, and energising is heating directly, and one can effectively bring into play heat energy, and it is bigger that the hot water effluent is measured, and temperature is more stable, and two can reduce the heater internal loss; And use the bend pipe water outlet, and help the storage of hot water, more protected heater; In use, when steam has formed dew point in the house, the H1 sensor makes moist, and IC1 module 17 pin become low level, IC1 module 20 pin output high level, and 1 pin of transmitter module IC2 gets electric work; 3 pin of receiver module IC5 obtain the instruction that transmitter sends, and amplify through the unidirectional controlled VS3 of resistance R 18 triggerings by triode V6 to make exhaust fan M2 get electric work exhaust (hypoxia protection).

Because the problem of water quality, heater will be stained with some dirts unavoidably, at this moment, is time set by AN4 with temperature transition, IC1 interior overturn 18 pin output high level when setting-up time, amplify to drive relay J 4 upsets through triode V4, the closed motor M1 of J4-1 gets electric, the hairbrush on the motor water towards the time drag up and down, left rotation and right rotation constantly cleans the dirt on the heater; When cleaning to the time of setting, 18 of IC1 becomes low level, relay J 4 dead electricity, and water intaking valve G1, high-pressure pump P1, motor M1 outage quit work, and at this moment manually open blowoff valve and carry out blowdown, Bian Chong, limit blowdown.

Because the inner electric leakage of the humidity of air or water heater itself, cause the water heater ectosome charged, at this moment be connected on 1 pin that R14 on the water heater ectosome gets electric IC3 and become high level, rapidly signal is passed to 4,5 pin of IC3 by optocoupler, made triode V5 amplify that the closed LED2 of J5-2 is bright, loudspeaker r1 sends chimes of doom; Simultaneously, J5-1 disconnects; Because the power series of relay J 1, relay J 2 is on the J5-1 closing point, when J5-1 disconnected, J1-1, J2-1 dead electricity were cut off heater and motherboard power supply automatically.
