An existing quick electric water heater is arranged in an open water storage tank to cause water pressure with different height to be changed into lower water pressure, thus solving the defects that when water pressure is low, cold water can not enter the water storage tank, when the water pressure is too high, a plurality of inner bags burst and leak water. Heating tubes are respectively arranged in the water heater and the water storage tank, and the water heater and the water storage tank can be heated in turn through a sensor and controllable silicon to cause cold water to become warm water firstly and then become hot water, thus reducing the power of the water heater, and shortening preheating time. The utility model not only can be used for a shower bath but also transports the warm water to places where the warm water is needed in winter by extending rubber tubes.
Description
The utility model belongs to the quick formula electric heater in the household electrical appliance.
The electric heater major part as shower of listing now is a water-storage electric heater, exists heat time heating time long, and the thermal efficiency is low; Also have because of hydraulic pressure cause too greatly in gallbladder break leak or can not advance cold water influence use because of hydraulic pressure hour push up not open non-return valve; And fast the formula electric heater have because of power can not enter average family too greatly, what have is on the low side because of the hot water productive rate, easy the to be charged poor stability that has and less listing.
The purpose of this utility model: provide a kind of employing gradation heating to make the short thermal efficiency of the time that preheats higher, can go out hot water fast and the quick formula electric heater of lower-powered Automatic Control.
The purpose of this utility model is achieved in that and changes quick formula electric heater into the gradation heating by traditional once heating, promptly earlier cold water is preheated proper temperature, heats once more during spray to make water temperature reach serviceability temperature.Concrete scheme is: quick formula heating tube is laid in the capsule be placed in the open type water storage case together with this capsule, in water storage tank, also lay a heating tube, cold water enters the open type water storage case hydraulic pressure that various height are different and becomes very little hydraulic pressure, when water level reached setting height, the ball float buoyancy was depressed inlet valve and is stopped into cold water through shouldering bar; When water temperature was lower than preset temperature, heating tube was connected automatically water is preheated in the water storage tank, and when water temperature reached preset temperature, sensor made heating tube outage stopping heating by controllable silicon.After the spray water valve is opened, warm water flows out through formula electric heater fast, water flow sensing unit, spray thrower in the water storage tank, because current sink the floating drum in the water flow sensing unit, the photo resistance of Light-Emitting Diode issued light directive, the relay make contact switched make heating tube energising heating in the quick formula water heater, with the warm water that flows into once more heat temperature raising reach serviceability temperature; Because switching the electricity of heating tube in water storage tank this moment, relay contact is cut off in order to avoid work simultaneously; The magnetic valve adhesive of having switched on is lifted lever by auxiliary lever during spray, and cold water can not enter water storage tank and keep the relatively stable of water temperature when making spray.Otherwise closing spray when the spray water valve stops, water stops to flow in the sebific duct, floating drum come-up in the water flow sensing unit, cut off optical channel, the photo resistance resistance becomes the rebound of ambassador's relay breaker point, release is shouldered bar cold water and is entered water temperature decline because magnetic valve also cuts off the power supply, and heating tube is switched on heating in the water storage tank, has realized heating in turn.
Owing to adopt such scheme, it is short that the utility model preheats the time than water-storage electric heater, and set water temperature is low thereby the thermal efficiency is high; It is littler than high-power quick formula electric heater power, can enter average family, and can be applicable to the cold water of lower water temperature; Because water storage tank adopts open type, can adapt to very wide range hydraulic pressure; Low and water is magnetized and is difficult for producing incrustation scale, long service life on the heating tube because of set water temperature; It can also provide the water of two kinds of different temperatures to use more convenient simultaneously.

Under the situation of connecting power supply and water source, cold water enters from direction shown in the arrow, flows in the water storage tank (6) through water inlet pipe (3) permanent magnet ring (4) inlet valve, with lifting on the water level rising ball float (10), make and shoulder bar (5) and rotate counterclockwise and depress inlet valve and close, cold water stops to flow into.The resistance that is in when water temperature is lower than design temperature with the cooling-water temperature sensor (2) of the same level height of heating tube (1) is in conducting state than ambassador BG1, relay (J1) adhesive K1 and contact, the right are logical, and (K1 disconnects the position after being in and reaching preset temperature among Fig. 2, K2 is in when spraying and left side contacting draws), owing to do not spray as yet, K2 is in and contacting position, the right, at this moment heating tube (1) energising heating temperature sensor (2) resistance after reaching design temperature diminishes, BG1 is become by conducting and ends, relay (J1) discharges, K1 and left side contacting and controllable silicon (VT1) is disconnected, heating tube (1) stops heating.Cooling-water temperature sensor is to be made also and can be made with thermistor by the heat-sensitive semiconductive diode.The warm water design temperature can be regulated W1W2 and be determined.
Fast formula electric heater (27) is installed in the water storage tank (its shell imagination shift out with double dot dash line represent), promptly be immersed among the warm water, its the inside is placed a heating tube (16) shell and is had aperture and intake from water storage tank, connect through sebific duct (11) and water flow sensing unit (15), when spraying water valve (22) when opening, stream of warm water in the water storage tank is through quick formula water heater (27), water flow sensing unit (15), and spray thrower (20) and spraying water, floating drum sank when stream of warm water was crossed floating drum (14) in the water flow sensing unit (15) (its shell imagination shift out with double dot dash line represent), photo resistance (12) receives that the photoresistance value that light emitting diode (13) is penetrated diminishes immediately, and BG2 is become by making BG3 by conducting, two triode conductings of BG4.Relay after the BG3 conducting (J2) energising makes K2 make the VT2 conducting with left side contacting, heating tube (16) energising heating, and temperature heated up once more becomes hot water for use.This has just finished the gradation heating.
The adjusting of hot water water temperature height can be adjusted by two knobs: first rotation water heater power adjusting potentiometer (19) is (W4) with the size (W4) of adjusting heating tube (16) heating power hour heating power maximum, as (W4) when increasing gradually, because W4C
2It is elongated that time constant became the last charging interval of big C2, reaches by bilateral diode (D
2) remove to trigger VT
2The phase angle of the control utmost point lags behind just that the angle of flow diminishes, and heating tube (16) is gone up resultant power and diminished; It two is the current sizes that change the spray water valve, and the big more water temperature of current is low more, and the more little water temperature of current is high more.Temperature detect switch (TDS) (26) disconnects immediately and stops heating when water temperature surpasses a certain temperature, and it plays non-ironing protective effect.
BG
3Also conducting simultaneously of BG4 during conducting, it makes the line bag energising magnetic valve adhesive of magnetic valve (9), and pulling is auxiliary to be shouldered bar (8) and drives lever (5) and close inlet valve and make that water temperature keeps constant in the water storage tank.Control Component (21) is very little, can and spray thrower (20) be placed on together and help the shower in winter in the cubicle.The dc source of circuit is provided by power transformer (24) full-bridge rectifier (25) and C1.D1 is a Zener diode.
Warm water can output to place far away by sebific duct (23) and use for the people who needs warm water winter, uses easily.Because this sebific duct directly takes out from water storage tank and does not pass through water flow sensing unit (15), can not exert an influence to water flow sensing unit.Because water is magnetized by permanent magnet ring, set water temperature is low, is difficult on the heating tube producing incrustation scale, makes the thermal efficiency improve long service life.
Otherwise when the spray water valve cut out, warm water stopped to flow, and the light source resistance that floating drum (14) come-up is cut off photo resistance (12) becomes ambassador BG rapidly
2Conducting BG
3BG4 ends, i.e. K2 and the right contacting, heating tube (16) stop heating; Magnetic valve cuts off the power supply and trip lever; Cold water refills water temperature and descends, and cooling-water temperature sensor (2) reheats VT1 conducting heating tube (1).So just realized the quick formula electric heater of gradation heating and Automatic Control.
