Flowing through the water of water tank, it is preferable to use electric devices to heat.More precisely, it is advantageous that be equipped with electricity for each water tank
Heating device.In this way, the supply power in each water tank can be adjusted individually so that can individually control heating water in water tank
It is flat.According to a possible embodiment, the electric heater provided for each water tank or in which at least one water tank is resistor,
And such as including resistive element, which is inserted into directly or by sheath in the storage vessel of considered water tank.
In alternative embodiments, at least one of water tank is equipped with the electric heater for using induction technology.It is preferred that
Ground, all water tanks all include such sensing heating.In Fig. 1 to example shown in fig. 5, for the water tank,
Induction heating apparatus is immersed in cylindrical inner volume.Its operation is irritability, that is, it powers to inductor, the inductance
Device itself is designed to generate magnetic field so that in the load, induced current preferably is generated in the load of the magnetic material of metal,
The load is configured to the energy transmission of hot form to the water being stored in water tank.This energy transmission can be it is direct or
It connects, such as there is intermediate thermal conductivity element between load and water to be heated.
In the example of fig. 1, each water tank shows in figures 4 and 5 equipped with the inductor being immersed in its inner volume
Example more precisely is gone out.In Fig. 4, inductor 20 includes electrical conductive elements, with elongated elliptical shape, and
Under the specific condition, in the form of closed contour.There is inductor 20 electrical connector 23, electric current to be carried by the electrical connector 23
Supply inductor 20.Short-circuit in order to prevent, inductor 20 is for example by insulating sheath or any other sheath or using circular
Close sheath is advantageously electrically insulated with its external environment.For example, cylinder of the inductor 20 along its water tank being disposed therein
Length in the range of the 30% to 80% of partial-length extends.In the present exemplary shown in a grid formation, 21 packet of load
Inductor 20 is enclosed without contact induction device 20.For example, load 21 can be made of two parts, two parts are especially flat
It is substantially symmetric and for example fitted together around inductor 20 using stud 22 in face.Therefore, the inner surface of load and induction
Device 20 keeps certain distance but relatively close inductor 20, to generate suitable induced current in the load with heating load,
To make load heat water.For example, the power input of inductor can be in the range of 1000W to 3700W, and preferably exist
In the range of 1000W to 2500W.
As shown, load 21 can have multiple holes.In this way, water can recycle between load 21 and inductor 20.
The cycle obviously improves the efficiency of heating surface, can realize more dynamic flow, and due at load close to phenomenon, especially
It is magnetic and vibrates close phenomenon and advantageously limit or even be eliminated the formation of lime stone.
Preferably, the longitudinal axis of water tank is parallel and is located in a plane, and the plane itself corresponds to and adds
A parallel plane in the surface of hot device shell 15, then will be described in detail.The plane is preferably located in outer
The centre of the thickness of shell 15 and it is expressed as " X ".In this case, even further preferably, the electrical heating in water tank fills
It sets and is oriented preferably also along longitudinal axis, what the longitudinal axis of wherein heating device itself was also in alignment with.Layout shown in Fig. 3
In, the front and back positioning each other of three electric heaters, axis orientation is in the mid-plane of shell, just as the longitudinal axis one of water tank
Sample.
Induction technology is preferably needed using generator shown in power supply system 10 as illustrated in fig. 1 and 2.Power supply system 10
It can be contained in box 11, and may include the electricity input that may be connected to electric network such as home network.10 turns of power supply system
Electric power is changed, so as to generate electric signal appropriate, for operating the induction apparatus being preferably provided in the heater.More specifically
Ground, power supply system 10 may include inverter system, the frequency for the scaled signal to be supplied.Such system
System typically results in the heat that can not ignore and distributes, this usually requires pressure gutter channel (the undissipateur à for its cooling
flux forcépour).In order to utilize this point, it is contemplated that heater is intended to heat, and carrys out dissipating for the heat of self-contained electric system 10
Hair is in partly heating water.For this purpose, the power supply system 10 with enter primary heater water tank before or
Heat is exchanged between the internal water of water tank itself.In the example shown, exchanger 12 is positioned to conductive with power supply system 10,
To collect the calorie that at least partly distributes, and exchanger 12 includes the exchange surface for having water loop, and the water loop is from can
The entrance 5 of the inlet connecting 14 being connect with such as home network towards cold water inlet upstream water tank 2 extends.It should be understood that flowing through friendship
The water of parallel operation 12 receives initial heating.In addition, this initial heating, which advantageously occurs in, is positioned over water heater components inlet
At water tank, it is assumed that water is most cold there.Therefore, it is most effective to cool down there for electric installation.Therefore, in sensing heating application
Shown in three-tank of the invention constitute, or more generally, more water tanks compositions this have the advantage that at the coldest water tank of water
The selectivity provided for electric installation 10 cools down.
Shown in constitute for heat exchanger that can be used according to the invention be non exhaustive.In fact, power generation
Machine can be integrated in a water tank and in especially the first upstream water tank, and be positioned to the bottom table with same water tank
17 thermal conductive contact of face so that it is towards inside or according to other composition conduction heats.Preferably, each water heater water of the invention
Case is equipped with induction heating apparatus.In this case, and it is alternatively possible to all heating devices for water tank provide individually
For electric installation.This composition corresponds to the composition in Fig. 1 and Fig. 2, figures 1 and 2 show that the sensing device provided for each water tank
Electricity input 13.It is not shown for the physical electrical connection between each in electric installation and these electricity inputs 13.
According to another possible embodiment, power supply system is alternately that each heater water tank supplies by switching device
Electricity.Can according to the temperature in each water tank adjust to control the switch, (each water tank can have at least one temperature sensing
Device).Therefore, switch order can be provided, to generate sensing heating in water tank one by one.
It is achieved that generator pond, to limit the cost of inductive component.This also allows for making full use of power supply
The cooling effect of system, so as to tentatively be heated to water inlet.If device is identical, generator is also simplified
It constitutes, because for all water tanks, the electronic parameter of such as impedance etc is identical.
As previously mentioned, the more water tanks exemplified by three-tank arrangement in Fig. 1 constitute and are covered with shell 15 herein, the shell
15 for example corresponding to the shell shown in Fig. 2 with rectangular shape.Rectangular shape means the part of water heater
Outer surface substantially has two parallel and flat main surfaces 16 being spaced apart by side wall 18, bottom wall 17 and roof.It is all these
Surface is advantageously flat, and includes the arrangement with picture on surface, these picture on surface are particularly for the connection in each wall
The beauty or fillet at place.Therefore, rectangular shape includes the similar measure that may be substantially limited to rectangular shape.It is shown in Fig. 2
Example in, be included in box 11 for electric installation outside shell 15.However, such case is indicative.Shell 15 to
The external aspect of few water heater that the present invention is constituted for its hot water storage part.Shell 15, which also defines, can use for example with poly-
The inner volume that the insulator 19 of the form of object foam is filled is closed, which advantageously fills outer surface and the shell of water tank
All or part of gap vessel between 15 inner wall.Preferably, internal clearance vessel is completely filled with insulator 19.
Previously it has already been indicated that the diameter of downstream water tank is advantageously below the diameter of upstream water tank 2.Therefore, as shown in figure 3,
It surround the more of the insulating materials of downstream water tank.
Therefore, the heat loss of downstream water tank is more limited.It can be increased using this insulation to adjust temperature.More precisely
The set temperature of downstream water tank 1 is given advantageously greater than at least one of upstream water tank 2 in a preferred embodiment in ground
Temperature (is at least used for some and uses cycle).Therefore, higher water storage temperature can be obtained in the water tank of downstream, reduced simultaneously
Usual higher heat loss in this case.Although those skilled in the art will attempt to optimize the water stored, the present invention
Antipodal way is taken, in this example, smaller diameter is selected for downstream water tank, this limits the water of storage really
It measures, but can realize the thermal efficiency of bigger in final heating.For example, in non-exclusive use cycle, the setting of downstream water tank
Temperature can be 5 DEG C to 30 DEG C higher than the set temperature of previous water tank, other water tanks are usually at 65 DEG C, in the last one water tank most
High-temperature is particularly set in 90 DEG C (having the safe clearance for preventing boiling), i.e., 25 DEG C or more.
In one embodiment, it is identical that the electric heater in water tank, which is arranged, so that the design of heater is simple
Change, and to be arranged the heating that available maximum heating power at the heating system in downstream water tank 1 is equal to other devices
Power.The inner volume of downstream water tank is smaller, the result is that the heating of water is more unexpected, this in some cases can be in supply heat
Almost instantaneous additional heating is realized during water.In one of possible and non exhaustive operation circulation of the present invention, for Denso
10 are set to be configured to when the downstream electric heater unit power supply of water tank when exporting conveying water at 6.For this purpose, flow rate detector can
To be used in water heater, especially at its outlet 6.The continuous of temperature change in water tank is divided by the microprocessor of generator
Analysis gives fairly precise water intaking assessment, and therefore expensive water need not be used to convey measuring device.In another behaviour
In recycling, it is configured to be periodically switched between each water tank for electric installation.According to another embodiment, it powers
The set temperature that device is configured to once reach water tank (wherein heating device is in active state) switches to another water tank.
Advantageously, the water tank that heating device is disposed therein then is switched to for electric installation, which determines farthest away from for it
Set temperature.In an alternative embodiment, there are 3 or more water tanks to adjust heating.If only needing a small amount of heat
Water, then heating will focus on the last one water tank, if necessary more water, then the last one water tank and penultimate water
Case will be heated to higher temperature, and if also needing to more water, all three water tanks can be heated to more
High temperature.
User can be estimated the hot water amount of needs.For this purpose, known learning algorithm can be used, it is included in one week
In several days in measure temperature in various water tanks and decline, to be heated according to the data prediction.This may accomplish, because
It is high degree of periodicity that domestic hot-water is used in one week.Yield will be regulated, to be slightly above consumption always, to use
Family will never lack hot water.The advantages of system, is its energy efficiency, because not will produce excessive hot water and later by
The natural heat loss caused by heat-insulated defect is cooled down in water tank.On the contrary, all service conditions all can not Accurate Prediction, and
Under special circumstances, the maximum power of generator can be distributed to small (downstream) water tank by system, to which it can be may be most
Additional domestic hot-water needed for being generated in the short time, this is impossible for large-scale single heater for cistern.
The present invention can also implement a kind of learning device, especially in for electric installation 10, so that the operation of power supply control
It is adapted to the custom in the place of installation water heater.For example, the learning device may include computer journey stored in memory
Sequence product, the computer program product can be accessed by processor and it can be considered that convey the average time work of hot water from water tank
For operating parameter.The device is also conceivable to charging regulation, including off-peak period and peak period.
Fig. 6 shows that the replacement of sensing device is constituted.In fact, front shows the heating dress being inserted into water tank
It sets.On the contrary, Fig. 6 shows the induction heating apparatus run outside water tank.In the alternate embodiments, an inductor 20
It is arranged in water tank and is formed about it and winding of all or part of length of cylindrical part of water tank therein is set.
As previously shown, winding is connected to for electric installation 10.In this case, at least part of the wall of the water tank assembled is by magnetism
