Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front schematic view of the present utility model.

Among Fig. 1, the 1st, shell, the 2nd, instant electric water heater, 3A are interior outlet pipes, 3B is outer outlet pipe, the 4th, circulation pipe, the 5th, circulating pump, 6A are outer water inlet pipes, and 6B is interior water inlet pipe, and 6C is the outlet pipe of interior water inlet pipe 6B, the 7th, valve, the 8th, minute water plate, the 9th, two-way position valve, the 10th, storage tank.

Among Fig. 1, in shell 1, there are 10, one instant electric water heaters 2 of a storage tank to insert the bottom of storage tank 10 inside.Instant electric water heater 2 is a metal cabinet, is separated into the pipeline space that linearity is ganged up formula in it, and sealing ground inserts electric heating tube in the linear pipeline space, and the electrical power wiring part of electric heating tube is placed the outside of storage tank 10 safely.One valve 7 (valve 7 can be electromagnetic valve or manually-operated gate according to actual needs) is arranged on outer water inlet pipe 6A of the instant electric water heater 2, extend then, before feeding instant electric water heater 2 inside also with an interior water inlet pipe 6C UNICOM (here 6C by water inlet pipe 6A outside complying with in the direction of current be inserted among the 6A), the diapire that the extension of interior water inlet pipe 6C penetrates storage tank 10 penetrates storage tank 10 again after connecting a power cycle pump 5 diapire returns the inside of storage tank 10, then with another interior water inlet pipe 6B and circulation pipe 4 UNICOMs, one fen water plate 8 mouth of pipe half point with interior water inlet pipe 6B and circulation pipe 4 is arranged in three ports of UNICOM, so that two bursts of current direct motions, work to reduce flow resistance, the other end of circulation pipe 4 and instant electric water heater's 2 outfall sewer UNICOM, the extension fork of outfall sewer, one becomes the interior outlet pipe 3A that is opened on storage tank 10 inside, another diapire that penetrates the diapire of storage tank 10 and penetrate shell 1 becomes outer outlet pipe 3B, interior outlet pipe 3A with outside one two-way valve 9 is arranged in the branch fork of outlet pipe 3B, two-way according to actual needs position valve 9 can be that hand also can be an electromagnetic type, when being electromagnetic type, the normally closed position of two-way position valve 9 blocks 3B, and open 3A.

Now the 1 pair of the utility model situation that is respectively applied for electrothermal water boiling water fountain and electric heating bathing device is made an explanation in conjunction with the accompanying drawings.

When being used for electric heating bathing device, valve 7 is opened under control, and cold running water enters instant electric water heater 2 inside and flows to the outlet pipe direction from outer water inlet pipe 6A, is subjected to the heating step by step of electric heating tube simultaneously, flows in the storage tank 10 from interior outlet pipe 3A at last.The water inlet in or the circulating pump 5 of slightly delaying time be unlocked, then flow out the part of water in the outlet pipe, and in the storage tank 10 the part of full water send into instant electric water heater 2 inlet end via circulation pipe 4 and interior water inlet pipe 6B and interior water inlet pipe 6C respectively and mix and in instant electric water heater 2, heat once again with outside cold running water endlessly.When the water in the storage tank reached predetermined water level, valve 7 was closed (hand or under the control of liquid level control switch self-action).At this moment the heating that under the acting in conjunction of the electric heating tube 11 of instant electric water heater 2 inside and circulating pump 5, circulates of the water in the storage tank 10.When whole water temperature reached a certain basal temperature in the water tank, electric heating bathing device sent sound equipment, and the prompting user can use.The user opens that bathing switch drive valve 9 is closed interior outlet pipe 3A and outer outlet pipe 3B is open-minded, the water that then has low basal temperature in the water tank 10 is under the circulating pump effect, entering in the instant electric water heater 2 from interior water inlet pipe 6B and 6C, is that hot mode flows out from outer outlet pipe 3B with what heat step by step.Being hung to certain altitude when the bathing device also can be without circulating pump 5 when above, only rely on the gravity effect of water own to make the water of storage tank 10 be inhaled into instant electric water heater 2 inside, with the cascade raising temperature heating is that hot mode flows out from outer outlet pipe 3B, but the situation of outlet pipe short circuit outside the water in considering in the water inlet pipe 6B can take place directly to enter from circulation pipe 4, therefore a minute water plate 8 can be removed, make the valve of a valve of controlling automatically (as the magnetic valve under check valve or the automatic control) or manual control into, perhaps also can consider simply to remove circulation pipe 4 to avoid the generation of this situation.

Here, the basal temperature of water can require the temperature of acquisition according to outer outlet pipe in the storage tank, the flow of the power of electric heating tube output size and outer outlet pipe in the electric heater, and these three parameters are calculated accurately.

At electric heating tube is peak power, when outer outlet pipe is maximum stream flow, if make four basal temperatures in adjustable mode, then correspondingly outer outlet pipe can obtain four different temperatures values accurately successively, under a certain accurate temperature value, if want temperature is reduced and can realize by the power output that reduces electric heating tube during bathing, if expect suitable rising, can reduce the flow of bathing pipe valve realizes, and as when temperature detector being set and on the LED panel, show on the outlet pipe, can control the change of temperature surely.

When the power output of electric heating tube is controlled by electrodeless adjustable turn-knob, can indicate four points on knob comes corresponding to 1/4 general power, 2/4 general power and 3/4,4/4 general power, and four leaving water temperatures when corresponding these four position outer outlet pipes of regulation are maximum stream flow, also can calculate four corresponding basal temperatures of water in the storage tank in view of the above, and interlock accordingly between four positions on the setting of these four basal temperatures and conversion and the electrical heating power output adjustment knob, thereby can accurately obtain four different leaving water temperatures.The power output that changes the electric heating tube of adjusting under the knob control in bathing can realize the change of water outlet to high temperature and low temperature direction, can certainly cooperate the flow of adjusting bathing pipe valve control water outlet to realize jointly, but in this temperature control scheme, realize that water reaches during a certain basal temperature in the storage tank, electric heating tube breaks away from the control of power knob with flat-out working method.

Various temperature control methods also have a lot, but are not the problem that the utility model will illustrate, so no longer stating more.

Water heater of the present utility model is when being used for bath apparatus, under the certain situation of design total capacity, it is also conceivable that water inlet with storage tank inside is divided into can select a plurality of sections of adjusting, to adapt to the different requirements that makes water consumption, also can consider in addition to establish an independently cold water inlet above the inner water surface of storage tank, its afterbody is made suitable sprinkle formula delivery port (can make even water temperature variation the water tank from the top moisturizing with the sprinkle formula).Water in storage tank is not too enough the time (can learn or otherwise allow the user learn by being presented at situation that the outside water level of bathing device descends), with mode appropriate moisturizing in storage tank of manually or automatically controlling flow of inlet water, reach moisturizing simultaneously and continue bathing simultaneously.Also can select peak level amount in higher baseline temperature and the water tank in advance, come the long or more situation of number of corresponding bathing time with the mode of manual or Automatic Control flow of inlet water moisturizing and the power output (manually adjusting or full-automatic the adjustment) that strengthens electric heating tube when the bathing adaptably in storage tank during bathing.

Water heater of the present utility model situation principle when being used for electric heating bathing device when being used for the electrothermal water boiling water fountain is identical, only the water in the storage tank only needs a basal temperature to reach 100 ℃ situation with water outlet in the outer outlet pipe of correspondence, and this basal temperature is kept by an automatic thermostatic controller, when water temperature in the water tank is lower than the basal temperature certain numerical value, circulating pump and instant electric water heater then stop the circulation heating to the water heating that circulates when reaching basal temperature.When needing 100 ℃ water, people then press or touch corresponding cock of water drain, then the circulating pump water that will have a basal temperature is sent into the heating that circulates in the instant electric water heater 2, slightly time-delay, after the water outlet in the interior outlet pipe reaches 100 ℃ of water temperatures, valve 9 is opened (adopt electromagnetic valves and its normally closed position that outer outlet pipe 3B is blocked and interior outlet pipe 3A is opened than place's valve 9) under corresponding temperature sensing device control, then 100 ℃ water is discharged from outer outlet pipe 3B continually and is closed until no longer needing.But above-mentioned temperature measuring equipment also can dispose, as long as the time of valve 9 Time Delay Openings is grown when arriving q.s, the water of emitting after then opening also can reach 100 ℃ requirement.

By above two introductions to the utility model electric heater application example, can find that its advantage is organically instant electric water heater and the whole hot type electric heater of water storage to be combined, it is when being applied to bath apparatus, the effect that reaches is need not resemble to adopt very high heating power the immediate heating type, so that can not use at average family, unlike the whole hot type of storage tank, need the long stand-by period again, it adopts the integral body heating under circulating earlier dexterously, reach low basal temperature at short notice, the water with this basal temperature is that starting point is carried out Instant heating type heating bathing more subsequently.It can also select some in several accurate leaving water temperatures, when bathing by adjusting that the output of the water yield and electrical heating power can realize with this " some " while accurate temperature be the variation of the positive temperature of basic point or negative temperature and can realize that also replenishing cold water continues bathing.When it was applied to electric drinking, it had only unlike plain edition and could use when whole water temperature is heated to 100 ℃ and deal with use under user's the time uncertain condition in the mode that is substantially constant at 100 ℃ unlike plain edition.It makes low basal temperature of determining according to self actual peak power and flow, and reach and keep this basal temperature, on the starting point of this basal temperature, can obtain 100 ℃ water at any time, thereby can as plain edition, not generate a large amount of incrustation scales, particularly when basal temperature is defined in a desired value, even the generation that might stop incrustation scale, it also needn't resemble the plain edition and to consume a large amount of for maintaining constant at 100 ℃.In addition, keep with the basis of constant temperature to be far smaller than 100 ℃ because of it, so the heat that sheds is also little than medium-sized to the influence of environment for use.
