- Household appliance with at least one heater for one
- the present invention relates to a water-conducting household appliance, such as a dishwasher, in particular domestic dishwasher, with at least one heatable from the outside and fluid flowing in the flow direction channel portion, wherein a plurality of electrically interconnected Schuleiterierin is provided for heating, surrounding the channel portion outside at least partially and enter area services in the channel section during operation (according to the preamble of claim 1).
- uniform heat removal from the heater by flowing fluid is particularly important for proper operation without forming excessively high temperatures at the heater. Since some users are e.g. If a domestic dishwasher does not operate as intended with salt in the softening with detergent and rinse aid, but omits at least one of these components, for example, forgets, then the dishwasher chemistry is not in equilibrium. On the heater then pads can form, which hinder the energy transfer into the fluid, which usually leads to a partial overheating of a heat conductor. This then usually results in a defect of the heating.
- the invention is based on the problem here to achieve an improvement in the life of the heater and to avoid defects as possible.
- the boundary wall of the channel section on which this segmented surface heating is provided is subjected to different thermal surface loads below the heating conductor elements corresponding to these subregions of locally varying surface powers, so that the coverings are applied to a lining formation which builds up on the fluid-flowed inner wall surface of the channel section Make jobs with higher thermal load faster than at places with lower load.

- the channel portion is encompassed by a circumferentially closed pipe section, such as steel.
- the pipe section is preferably cylindrical, in particular circular cylindrical, formed.
- the pipe section in particular the pipe section, is traversed internally along its longitudinal extent by the fluid to be heated.

- the respective heating conductor has a geometric shape in the form of an elongate trapezium.
- a heating conductor which tapers from the entrance of the pipe section to the outlet of the pipe section, follows in the circumferential direction, an adjacent heating conductor which widens complementary to the previous heating conductor from the entrance of the pipe section to the outlet of the pipe section.
- a simple and effective design provides that every other form of Edelleitermaschinen parallel to the flow direction of the fluid tapers and expands each adjacent form of Edelleitermaschinen parallel to the flow direction.
- the distance transverse to the flow direction between the adjacent shapes in the flow direction of the fluid can be constant and low, for example between 0.4 and 5 millimeters between each other, in order to achieve the highest possible occupancy of the surface with heating conductors.
- at least 85% of the circumferential surface of the channel to be heated, ie its lateral surface extending in the direction of flow, are at Heating conductor elements occupied.
- the said distance is smaller than the transverse extent of a respective heat conductor at this point.
- At least a part of the heating elements is electrically connected in parallel with each other, so that in case of failure of a Schuleiterelements the adjacent remain unaffected.
- the first electrical conductor for the first electrical potential at about the beginning of the pipe section and the second electrical conductor for the second electrical potential in the flow direction of the fluid are provided approximately at the end of the pipe section.

- FIG. 2 is a detail view of a arranged in the base of the household appliance heating pump for combined fluid delivery and heating, 3 shows the heating pump of Figure 2 in an exploded view of their parts,
- FIG. 5 shows a perspective view of the heatable tube section with the arrangement of the heating conductor elements according to FIG. 4,
- FIG. 6 is a view similar to Figure 5, wherein the view is rotated relative to Figure 5 in the circumferential direction of the pipe section,
- Fig. 8 alternative ways of occupying the pipe section by Schuleiter- elements.
- the water-conducting household appliance 1 shown schematically in FIG. 1 here is a dishwashing machine, namely a domestic dishwasher. Also, a washing machine or other device in which a fluid is heated, such. a coffee maker come into consideration.
- the drawn here dishwasher has as part of a partially open to the outside or closed device body 5 a washing container 2 for receiving ware to be processed dishes, pots, cutlery, glasses, cooking utensils u. on.
- the items to be washed can, for example, be loaded in loading units 10, 11, namely according to the drawing in dish racks 11 and / or a cutlery drawer 10, and can be acted upon by so-called rinsing liquor.
- the loading units 10, 11 can be designed, for example, manually or by motor and automatically height-adjustable or without height adjustment. In Figure 1, the loading units 10, 11 are shown partially pulled out to the front side V of the dishwasher, which faces the user in the installed position.
- the rinsing container 2 may have an at least substantially rectangular floor plan with a front side V facing a user in the operating position.
- This front V can form a part of a kitchen front of kitchen furniture standing side by side or even be without reference to other furniture in a stand-alone device.
- the washing container 2 can be closed by a door or flap 3, in particular on this front side V.
- the washing container 2 can be opened for its loading and unloading or closed for the flushing operation via this door 3.
- the front door 3 is here by way of example in the direction 4 pivotally, which is not mandatory.
- Figure 1 it is shown in partially open and then inclined to the vertical position. In its closed position, however, it is upright and is according to the drawing to its opening about a lower horizontal axis, which serves as a door hinge axis 13, swung forward and down in the direction of the arrow 4, so that it is at least almost horizontally in the fully open position.
- the user facing the outside door 3 may be provided with a decorative plate 6, so as to experience a visual and / or haptic appreciation and / or adaptation to surrounding kitchen furniture.
- the dishwasher is designed here as a stand-alone or as a so-called. Partially integrated or as a fully integrated device. In the latter case, the device body 5 can also be substantially complete with the outer walls of the washing compartment 2. A surrounding this exterior housing can then be dispensed with.
- a base 12 for receiving in particular functional elements, such as a circulating pump for rinsing liquor, are located. In particular, this circulating pump can also be heated, for example at its diffuser space To bring the rinsing liquor to the desired temperature in each program step. Then, a combined heat pump 17 is formed.
- the movable door 3 is assigned in the embodiment according to the drawing in its upper part a transverse direction Q of the dishwasher extending control panel 8, which may include an accessible from the front V engagement opening 7 for manually opening and / or closing the door 3. This is therefore preferably a so-called semi-integrated device.
- the dishwasher In the transverse direction Q, the dishwasher often has an extension of 45, 50 or 60 centimeters. In the depth direction T from the front V to the rear, the extension is often also about 60 centimeters. The values are not mandatory.
- the dishwasher can stand on an outer bottom B, which is ideally at least almost horizontal.
- the dishwasher or the other domestic appliance 1 has at least one channel section 14 which can be heated from the outside and can flow through the fluid 15.
- fluid 15 for example, water comes into consideration, which may be mixed with detergent, rinse aid and / or a drying agent. Such a fluid is often referred to as a rinse liquor in a dishwasher.
- a plurality of electrically interconnected heating conductors 16 are provided, which are applied to a carrier, for example a pipe section 18.
- This pipe section 18, for example surround the channel section 14 circumferentially on the outside, have a round-symmetrical cross-section and here form an integral part of the heating pump 17, namely the diffuser space.
- this is not mandatory, but increases the integration and reduces the space requirement and the number of components required.
- the application of the heating conductors 16 may e.g. by a printing process, plasma coating or other method of forming layers. Each of these layers forms a heating conductor 16 for itself. Overall, a thick film heater 19 is therefore formed on the outside in particular.
- the heating conductors 16 are present in a plurality and at least partially electrically connected in parallel to one another and in each case arranged with a component in the direction of flow F of the fluid 15.
- two different electrical potentials are formed, between which the heating conductors 16 are extended.
- two electrical tracks are provided on the outside of the wall of the channel section for providing two electrical potentials at both ends of the respective heating conductors.
- a first electrical conductor for the first electrical potential at about the beginning of the pipe section and a second electrical conductor for the second electrical potential in the flow direction of the fluid is provided approximately at the end of the pipe section.
- the heating conductors extend between these two interconnects or their potentials.
- the heating conductors are thus electrically connected in parallel with each other.
- the Schuleiterieri 16 surround the channel section 14 over a substantial part of its outer surface and carry in operation, in which they are current flowing, area services in the channel section 14 a.
- the tube section 18 enveloping the channel section 14 is acted upon by the multiplicity of heating conductor elements 16, which are preferably electrically connected in parallel with each other, at their location outside the tube section 18, depending on location, varying with different thermal surface loads.
- This causes a heat input at the respective location of the heating element per given heat input surface such as per 1 cm 2 in the shell of the pipe section 18 and corresponding thereto in the channel section 14.
- this entry is not uniform over the entire surface, but such that the or each Bankleiterelement 16 generated over its course varying surface powers, which leads over the course to different surface temperatures at the thermal transition into the channel section 14.
- the area input to electrical power and, concomitantly, thermal energy or heat does not only change over the course of a single respective heating conductor element 16 parallel to the flow direction but also transversely, in particular perpendicular, to the flow direction F over the circumference of the line Channel section 14. Because over the circumference of the channel section, the heating element 16 also adjoin one another with different surface powers.
- the registered area powers therefore vary both in the circumferential direction and in a direction parallel to the flow direction F of the fluid 15.
- the variation of the area performance can be achieved differently, for example by material transitions within the heating elements or by varying their thickness.
- heating elements 16 are provided in different shapes 16a, 16b and distributed over the circumference of the channel portion 14, the different shapes 16a, 16b additionally changing their outline shape parallel to the flow direction F of the fluid 15.
- FIG. 8 shows only diagrammatically that, for example, a large, wide conductor track can also be divided by a wavy line into two complementary subsections 23a, 23b. The same applies to the adjacent trace 24a, 24b. Here the division is represented by a multi-curved wavy line.
- the area output varies in the range from 10 W / cm 2 to 120 W / cm 2 , in particular in the range from 20 W / cm 2 to 80 W / cm 2 varies, particularly favorably in the range of 35 W / cm 2 to 75 W / cm 2 .
- the molds 16a, 16b of heating conductor elements 16 are designed to be complementary to one another such that a maximum area of the circumference of the channel 14 is occupied by heating conductor elements 16.
- the respective heating conductor has a geometric shape in the form of an elongate trapezium.
- a heating conductor which tapers from the entrance of the pipe section to the outlet of the pipe section, follows in the circumferential direction, an adjacent heating conductor which widens complementary to the previous heating conductor from the entrance of the pipe section to the outlet of the pipe section.
- the first shape 16a of heating element elements 16 tapers parallel to the direction of flow F of the fluid 15, whereas each shape 16b of heating element elements 16 which is directly adjacent thereto widens parallel to the direction of flow F. Due to this web width variation, the thickness and material composition in the respective heat conductor element 16 can remain constant and yet a varying surface load can be achieved.
- each Schuetzleiterelement 16 has over its course a web width variation of up to 3: 1, in particular of 2: 1 or slightly below. Halving the width involves a fourfold increase in power density.
- the distance a1 across the flow direction F between the adjacent molds 16a, 16b can be kept constant in the flow direction of the fluid 15.
- the heater in particular the thick-film heater 19 already described above, is in any case formed with a multiplicity-preferably 10 to 60, in particular 20 to 40-of heating conductors 16 which are connected in parallel to one another and are arranged side by side over the handling.
- each heating element 16 has a longitudinal extent which is considerable in comparison to its width extension. This longitudinal extent is at least substantially parallel to the flow direction F of the fluid 15. This direction also dictates the arrangement of the heating conductors 16.
- the heating conductors 16 have transversely to the direction of flow F a small distance a1 in the transverse direction between 0.4 and 5 millimeters between each other in order to achieve a high occupation density with heat conductors 16 over the circumference, as shown approximately in the imaginary unrolled figure of Figure 7 is.
- This distance a1 is smaller than the transverse extent b1 of a respective heating conductor 16 at this point.
- the expression should be such that the region 20 with approximately the highest area output in the near range (distance less than 10 millimeters) of the temperature sensor 21 is located.
