Description
The present invention relates to a kind of water heater, this water heater has a heating module, and this heating module moves towards ringwise at it and thermal treatment zone inner space that be connected with an outlet with an import contains at least one tubulose calandria.
By the disclosed water heater of DE10130610A has an annular in its thermal treatment zone inner space, wherein do not have the tubulose calandria of two heater stages, and water flows to a direction in pipeline.Undesirable is that in such design, cold water can mix with the water that heated.Because bigger flexibility, the zone that on tubulose calandria extension, outwards has high power density, these zones can not be cooled off in the continuous ring-shaped inner part space of circumferencial direction fully.
The object of the present invention is to provide a kind of water heater of mentioning in beginning, mixing of uncontrollable cold water and hot water wherein can not appear when its work, and in its thermal treatment zone, based on bigger power density, the key area of tubulose calandria is cooled off fast.
This task solves by a kind of water heater.This water heater has a heating module, and this heating module moves towards ringwise at it and thermal treatment zone inner space that be connected with an outlet with an import contains at least one tubulose calandria.According to the present invention, the thermal treatment zone has an interrupt unit that limits two flow path starting points of separating in toroidal extension, in interrupt unit, be provided with a inflow region towards the flow path starting point, and an outlet device of the thermal treatment zone that is connected with the outlet of heating module is away from inflow region, and the position of this outlet device makes from entering the zone isometric to two flow paths of outlet device.
Because interrupt unit can stop the circular loop of water, and forces water to flow to outlet device along two flow paths, thereby avoid mixing of cold water and hot water.Because always be in the flow regime of setting, and cold water must enter at predetermined heating region, because bigger power density can be provided with the key area of each tubulose calandria at this, thereby it is cooled off very fully.Can improve the security of work like this, and prolong the life-span of each tubulose calandria.
Suitable is to have set two inflow paths that flow to the thermal treatment zone that separate at inflow region.Therefore in flow process, realize favourable flow condition, the water that evenly flows is constantly heated along each flow path, and at the outlet device place with when leaving the thermal treatment zone, reach maximum temperature.Mixing of cold water and hot water can not appear in flow process.
Outlet device can separately receive the water in each flow path in case of necessity, further leads again.But preferred solution is only to design a discharge outlet, is used jointly by two flow paths.
Up to interrupt unit, the thermal treatment zone is annular as far as possible.Flow channel in outside, the thermal treatment zone and ring-shaped inner part extend, flow channel extends to an inlet union that is positioned at herein there.Be installed in annular outboard at one, at least one drainage channel extends along the outside of annular between the outlet connection of contiguous interrupt unit and the outlet device.Though by this way, it is very near that flow ipe and drainage pipeline are arranged ground each other, the flow path wide apart of cold water and hot water, thus undesirable heat exchange can not take place.
The joint that begins from the flow ipe of ring-shaped inner part, an intake channel of crossing interrupt unit is extended by import comes.It is an insert of installing in the last assembly process of heating module.Therefore just avoided undesirable reliably by the transfer of heat of hot water to cold water.
The suitable length of interrupt unit is about 1/3rd to 1/5th, preferred 1/4th of an annular total length.With the size of this interrupt unit, flow channel can keep neatly (sauber), thereby generation is smooth and easy in two flow paths, uniformly current.On the other hand, in order to obtain big as far as possible volume in the thermal treatment zone, and obtain relatively long flow path for circular heating module, interrupt unit can only be as much as possible little.
Consider the forming technique structure of heating module and the optimum utilization of heating power, should have a tubulose calandria in the thermal treatment zone, roughly to extend to another flow path starting point continuously at least, but be no more than interrupt unit from a flow path starting point.
In suitable embodiment, the tubulose calandria in the thermal treatment zone forms two about sweeps of 90 ° respectively to its link, and forms one 180 ° sweep at reverse zone, wherein make sweep be positioned at two flow path starting points near.By such structure, in the process of flowing through because bigger power density and cold water that crucial sweep is just flowed into well cools off.
According to another advantageous embodiment, in the thermal treatment zone, be provided with the tubulose calandria of two stacked similar structures at least with the link that staggers.Such as water heater can move on two different power grades.Each tubulose calandria at it because bigger power density and the cold water that all flowed in the crucial zone well cools off.
In another embodiment, only be provided with the tubulose calandria of a single-piece in the thermal treatment zone, this tubulose calandria divides multi-line ground, and preferred two circuit ground in planar annular, and extend perpendicular to planar annular.For the key area that makes the tubulose calandria promptly cools off, these zones are positioned near the flow path starting point.
In the operation and confined state of water heater, the planar annular of the thermal treatment zone should be basically be arranged vertically with the interrupt unit of directed downwards and the outlet device that is positioned at the top, and wherein import and outlet can be positioned at the below.Such confined state can impel current along two flow paths, because because physical cause, the water of heating can flow to the top, arrives the outlet device of top then.Water temperature always reaches maximum at the outlet device place.
Because the highest water temperature occurs at the outlet device place up, therefore can make the thermal treatment zone that the bimetal release of attaching troops to a unit is arranged suitably there, bimetal release can be in temperature be cut off the electricity supply during too high or fault, also can provide the adjusting parameter for the adjusting of heating power.
The cross section of the thermal treatment zone should be many times of the cross section of each inflow path and outlet device or discharge outlet, thereby produces the intermediate storage vessel of the water of a big relatively volume.By this way, after of short duration current interrupt, the water supply of absolute a large amount of heat is just arranged, like this, feeling that not under the situation of starting time, water heater just can provide hot water at once once more.
Under a preferred embodiment, heating module is circular substantially.It is made up of two injection molding spares that link together, and these drip moldings can be produced in enormous quantities at low cost, and satisfies the design details of all requirements.The circular design of heating module can guide two flow paths by inflow region earlier outwards, and then inwardly towards the curved extension of outlet device.Perhaps also can select one to depart from (abweisend) crooked extending contour for two flow paths.Flow path also can extend along the polygon path, perhaps stretches near circular central.
Below, describe embodiment of the present invention in conjunction with the accompanying drawings in detail, wherein:
The perspective view of Fig. 1 water heater (outer cover is removed) is first kind of embodiment, and calandria is not shown;
The upward view of the water heater profiled member that Fig. 2 shows in Fig. 1 is another embodiment.
The water heater that Fig. 1 shows for example is a so-called shower heater, and it for example is used at least one instant shower heater at least under installation shown in Figure 1 and duty.Next the structure principle of describing of water heater also generally is applicable to other through type water heaters and similar home appliances.
The critical piece of the water heater W that Fig. 1 shows is the heating module M of a circle, and it can be by two interconnective, as for example to weld injection molding spare compositions.Be in operation, water heater is covered by an outer cover that does not show in Fig. 1, and outer cover can be made the ball collar shape, and is locked together with heating module M, and wherein cover closely surrounds most of circumference of heating module M.
Heating module is by import Z supply cold water.Hot water is discharged by outlet A.Below import Z and outlet A are positioned at, and one section intermediate distance is arranged in embodiments shown.Two profiled members 1,2 limit a thermal treatment zone H in inside, in embodiments shown, this thermal treatment zone is for constituting the interrupt unit U in inflow region E circlewise.In drip molding 1, can design a jack 3 that bimetal release B can be inserted.This jack 3 is positioned at the thermal treatment zone, and here hot water reaches maximum temperature.Two drip moldings 1,2 limit a sheet type box D each other, this sheet type box is used under preferred heating power and mobile relevant connection, and, thereby generate necessary on-off action power by the pressure differential that in flow process, produces with a built-in Venturi nozzle acting in conjunction that does not demonstrate.
Intake channel 5 extends to joint 4 on the drip molding 1 by the import Z of annular outboard.Intake channel can be a plug-in unit that extends above the wall of the qualification interrupt unit U of drip molding 1.Equally also there is the drainage pipeline 7 of a bending to extend to the joint 6 that connects outlet A in the outside of thermal treatment zone H.To the cover plate of thermal treatment zone H, contiguous interrupt unit forming U shaped articles has the tubulose calandria K1 that does not show in Fig. 1, the through hole 8a of the link of K2,8b (respectively in pairs).If water heater W then only needs a pair of through hole 8a or 8b. only by a tubulose calandria K1 job
Below in conjunction with Fig. 1 and Fig. 2 the structure of trend of the current among the heating module M and tubulose calandria is elaborated.
Fig. 2 is the upward view of drip molding 1 among Fig. 1, but according to another embodiment, has only one by multi-line, the definite tubulose calandria K1 that says so and be made of double-circuit.Thermal treatment zone H be the annular the depression with U-shaped cross section 9, this depression is opened wide from the figure paper plane, in the heating module M that installs by one of another drip molding 2 flat substantially cover closure.The depression 9 in two outsides (Umrissseiten) by the sealing or the welding edge 10 limit.There is a flow channel 11 to extend to be arranged in the inflow region E of the interrupt unit U of annular from joint 4.
In flow channel 11, for example can be provided with a Venturi nozzle as already mentioned, promptly be configured as the independent parts of making and using, perhaps directly form in the inside of flow channel 11 as a whole.Flow channel 11 branches into two independently inflow paths 12 in interrupt unit U.Each inflow path 12 injects water the thermal treatment zone or caves in 9 in flow path starting point 13 or 14 places.In the thermal treatment zone, approximately an outlet device 15 is arranged with the relative straight design in position that flow channel 11 branches into two inflow paths 12, it can have such as two mouths that separate, or also can have only a discharge outlet as shown in the figure.From flow path starting point 13,14 two flow path R1 that separate are just arranged like this, R2 extends to common outlet device 15.On discharge outlet 16, connecting the drainage channel 7 of guiding joint 6 and outlet A into.If necessary, can design the drainage channel 7 that two outsides along thermal treatment zone H are curved course.
On the tubulose calandria K1 that shows in Fig. 2, have the link 17 that is basically perpendicular to the figure paper plane, these links can perhaps as shown in Figure 2, stretch out by another drip molding 2 by through hole 8a or the 8b in the drip molding 1.Between the circuit 18 of each link 17 and the tubulose calandria K1 that in the H of the thermal treatment zone, extends, form one 90 ° sweep 19.Circuit 18 passes through in the inside of thermal treatment zone H, and up to another flow path starting point 14, here it turns to the outside on one 180 ° sweep 20, and extends downwards in circuit 21, up to another sweep of 180 ° 22.Therefrom, another circuit 23 continues to extend to another flow path starting point 14 below circuit 21, and here it curves inwardly below this sweep, and turn back to another link with the same at 180 ° of sweep 20 places.Because the crucial sweep 19,22,20 that bigger power density produces is positioned near the first and second flow path starting points 13,14, thereby make the cold water cooling that they constantly flow into by (z ü gig) rapidly in the flowing of water.
Interrupt unit U needs one to account for and preferably account for 1/4th radian X between total annular length about 1/3rd to 1/5th in annular solid.
Because between flow path starting point 13,14 and the outlet device 15 very big distance is arranged, cold water can not mix with hot water.The highest water temperature always appears at drainage arrangement 15 places.Because the cold water that the key area of the tubulose calandria that produces than high power density is flowed into cools off rapidly.
Can construct two tubulose calandria K1 according to the embodiment among Fig. 1, K2, suitably with the overlapping placement of tubulose heater, separated from one another then, and separate with the inwall of the thermal treatment zone.
