Definitions

  • the invention relates to an electrical device with a water inlet, a water outlet, and an electric heater for heating the like in a tub, container, drum or the like. water used in the device for cleaning purposes.
  • a washing machine or a dishwasher may be mentioned as an example of such devices.
  • an immersion heater is arranged at the lowest point within the tub. To save space, this immersion heater is arranged very close to the walls of the tub.
  • the invention has for its object to provide a device of the type mentioned, in which the risk of damage to the device or its contents by overheating should be prevented in the event of failure of individual functions or protective devices of the device. At the same time, the costs of manufacturing and maintaining the devices should be kept low.
  • the invention proposes a device of the type mentioned in the introduction, in which the heating is designed as a water heater and is arranged outside the tub at a distance from it. If the water supply fails or the function of a temperature limiter, if any, only heats up or overheats the actual instantaneous water heater, but no longer overheats the tub due to the distance between the heating and the tub.
  • the invention provides that the heating has a temperature-resistant protective cover. This means that the entire heating is limited to the protective cover even if all systems fail.
  • the invention proposes that the heating radiator has a high surface area.
  • the invention further proposes that the protective cover has temperature-resistant thermal insulation.
  • This heat insulation can be attached to the outside of the protective cover, but it can just as well be attached to the inside of the protective cover.
  • the water inlet into the instantaneous water heater has a larger cross section than the water outlet. So that there is always a certain upper pressure inside the instantaneous water heater, so that the instantaneous water heater can be arranged both on the top and on the bottom of the device and in any intermediate position. To reinforce this measure it is also provided that the water inlet and the water outlet are mutually offset.
  • various devices can be present to ensure thorough mixing or swirling of the water to create. For example, baffles or baffle plates can be arranged in the water heater.
  • the radiator itself is designed in such a way that it ensures thorough mixing or swirling of the water in the continuous-flow heater.
  • the actual heating element generally consists of a metallic tube, inside which a resistance wire is arranged in an insulated manner. In order to achieve a good mixing of the water, this tube can be meandering, loop-shaped or helical, for example.
  • radiator and / or the water inlet and / or the water outlet and / or at least one protective tube for a temperature sensor or a temperature limiter is inserted into corresponding recesses in the protective cover and connected to it in a sealing manner, preferably soldered or welded, is particularly favorable.
  • the protective cover is formed in several parts, the edge of at least one of two abutting parts possibly being bent over to form a connecting surface. This enables a simple production possibility for the instantaneous water heater.
  • the radiator, the water inlet or the water outlet and the protective tubes can preferably be arranged on a part of the protective cover.
  • the protective cover consists of two parts
  • a particularly cheap and inexpensive connection between the two parts can be achieved by folding the edge of one part of the protective cover with a seal around the edge of the other part and compressing it tightly.
  • the instantaneous water heater can be built particularly small and compact, which makes it possible for the heating element to burn out easy to replace entire water heater. It is of course also possible to weld or solder the individual parts of the protective cover together.
  • the shape of the protective cover can be adapted to the respective purpose.
  • the protective cover it is possible to give the protective cover the shape of an elongated, wide and flat cuboid, one part of which forms the lid of the cuboid.
  • the individual parts of the instantaneous water heater are arranged in the lower part of the protective cover.
  • a likewise favorable embodiment is present, however, when the protective cover is tubular and the heating element extends helically around the longitudinal axis.
  • good swirling of the water and good utilization of the heating can be achieved in that the distance between the windings of the heating element increases from the inlet side to the outlet side. This means that the incoming cold water is acted upon more strongly by the heating, while the water that has already been heated is acted upon only weakly. This also results in less limescale.
  • FIG. 1 schematically shows a dishwasher in which a tub 12 is arranged inside the housing 11. Two baskets 13 for receiving the dishes are arranged within this tub 12. A rotating nozzle arm 14 is arranged below the one basket and between the two baskets, from whose nozzles the water for cleaning the dishes emerges.
  • the water passes through the supply line 16, which can be closed by a valve 15, into the continuous-flow heater 17, from where it reaches the collecting nozzle 19 via the line 18.
  • the circulation pump 20 sucks the water out of the collecting nozzle and presses it through line 21 through the two nozzle arms 14.
  • an outlet is formed in the bottom, from where the water reaches the water outlet via the pump 22.
  • an electrical line 23 with a plug 24 is attached.
  • the details of the instantaneous water heater 17 are shown in FIG. 2.
  • the instantaneous water heater 17 contains an external protection cover 25 in the form of a tube which is closed on both ends with a closure plate 26 and 27, respectively.
  • the heating element 28, which in the example shown here is helical, runs inside the protective cover 25. It can clearly be seen that the distance between two turns increases from left to right, ie from the water inlet to the water outlet.
  • the closure plate 26 on the left in FIG. 2 is provided with a water inlet socket 29, while the right closure plate 27 is provided with a water outlet socket 30.
  • Both nozzles 29 and 30 have the same dimensions, so that the lines or hoses used to connect the instantaneous water heater can have the same size.
  • a disc 31 is inserted within the water outlet connection 30, which has a hole 32 in its center. The area of the hole is, however, significantly smaller than the cross section of the water inlet connector 29. This results in an overpressure within the instantaneous heater 17, which makes it possible to arrange the instantaneous heater 17 at any point on the dishwasher.
  • the closure plate 27, see Fig.5, has a hole into which a protective tube 33 is soldered.
  • This protective tube extends in the longitudinal direction of the protective cover 25, but is arranged somewhat offset with respect to the longitudinal axis.
  • the protective tube 33 serves to receive a controller sensor for temperature control.
  • the water outlet connection 30 is offset with respect to the longitudinal axis and is arranged downwards.
  • the water inlet nozzle 29 arranged on the other end of the instantaneous water heater 17 is arranged offset in the other direction with respect to the longitudinal axis.
  • the left closure plate 26 also has holes, in which the two ends of the radiator 28 and a further protective tube 34 for a limiter sensor are soldered.
  • FIG. 3 and 4 show a further embodiment of a water heater designed according to the invention.
  • This water heater 35 has a protective cover 36 in the form of a long flat cuboid.
  • the protective cover 36 consists of two parts 36a and 36b, of which one part 36a represents a deeper trough, while the other part 36b represents a flat trough.
  • the edges 37 and 38 of the two parts are bent outwards at right angles, so that they form a widened connecting surface.
  • the two parts 36a and 36b of the protective cover 36 are welded to one another along this connecting surface. Another mounting option is shown in Fig.6.
  • the deeper part 36a of the protective cover 36 has two heating elements 39, the ends of which are inserted through corresponding bores and soldered to the part 36a.
  • the part 36 a also has a protective cover 33 for a temperature limiter. Both radiators 39 run, see FIG. 4, in a meandering shape through the interior of the protective cover 36.
  • the water inlet connector 29 is soldered at one end of the part 36a of the protective cover 36, while the water outlet connector 30 is arranged at the opposite end of the part 36b.
  • the water flows in the direction of arrows 40 through the interior of the instantaneous water heater 35.
  • FIGS. 3 and 4 show a type of fastening of two parts of a protective cover.
  • This type of connection is possible, for example, in the embodiment according to FIGS. 3 and 4.
  • the edge 41 of one part of a protective cover is bent outwards at a right angle, while the edge 42 of the second part is also initially bent outwards at right angles.
  • a seal 43 is then placed between the two edges 41 and 42.
  • the protruding part 49 of the edge 42 is bent back by 180 °, a strong force being exerted in the direction of the arrows 44, in order thereby to press the edges together watertight.
  • connection according to FIG. 7 can be used, for example, in a water heater that corresponds to the exemplary embodiment according to FIG.
  • the two parts 45 and 46 of a protective cover run at right angles to one another in section, while in the example according to FIG. 6 the two parts ran parallel to one another.
  • the edge 47 of the part 45 is bent upwards at right angles, the part 46 is placed against this edge 47 with the interposition of a seal 48 and then bent downwards by 180 °.
  • the seal 48 comes to rest between the edge 47 and the part 46. Then, as explained in FIG. 6, a strong force is exerted in the direction of the arrows 44, so that here too the two parts 45 and 46 are pressed tightly.
  • the protective cover can be easily and inexpensively manufactured with the radiator, which makes it possible to replace the entire instantaneous water heater in the event of failure.
  • the instantaneous water heater shown in FIG. 8 also has a tubular protective sleeve 25, which is closed at both ends by means of a plate 26 and 27, respectively.
  • the heater 28, the protective cover 33 and a further protective cover for temperature sensors, not shown in the figure, are soldered into the plate 26 on the left in FIG.
  • the water inlet and the water outlet run radially opposite the protective cover 25.
  • the water inlet is designed as a tubular connection piece 51, which projects radially into the protective cover 25 at its right end directly next to the plate 27.
  • the connection piece 51 which projects almost to the opposite side wall, is closed off at its inner end by means of a plate 52.
  • the outlet of the water flowing in the direction of the arrow 53 from the nozzle 51 allows four holes 54, which are arranged in the wall of the nozzle 51 and cause the water to flow radially out of the nozzle 51.
  • Two openings are directed in the direction of the corresponding end or on the closing plate 27, so that there is also a flow around the right part of the connecting piece 51 in FIG. 8. This ensures that the water does not stop anywhere in the instantaneous water heater.
  • FIG. 8 At the other end of the continuous-flow heater shown in FIG. 8 there is also a radially extending water outlet connection 55.
  • the neck also protrudes somewhat into the interior of the protective cover 25 and is closed at this end with a closure plate 56.
  • the nozzle 55 has on its side facing the end of the protective sleeve 25 near it a slot-shaped opening 57 through which the water passes from the instantaneous heater into the nozzle 55 and further in the direction of the arrow 58. Again, the water must first flow to the end of the protective cover 25 before it can leave it. It is also achieved here that there are nowhere in the protective cover 25 in which the water is not moved.
  • the embodiment of the continuous-flow heater shown in FIG. 8 can also be arranged in a washing machine or a dishwasher, as is shown schematically in FIG. 1, that is to say running horizontally. However, it can also be arranged in the vertical direction. This instantaneous heater reliably prevents the formation or non-disappearance of air bubbles.
  • FIG. 9 A further embodiment is shown in broken representation in FIG. 9, which is otherwise designed in exactly the same way as the embodiment according to FIG. 8.
  • the water inlet connection does not run radially, but axially to the protective cover 25. It is arranged in the center line of the protective cover 25 and projects with its inner end into it. The inner end is closed by a closure plate 60 which has an opening 61 in its center.
  • the nozzle 59 also has two radial openings 62. This also ensures that the water flows everywhere in the protective cover 25.
  • the water outlet nozzle is arranged radially in this embodiment, as shown in Fig.8.
  • the vertical arrangement of the water heater according to Figure 2 also has the advantage that no air bubbles can arise.
  • FIG. 10 shows a partially sectioned side view of a further embodiment of a water heater. It differs from the embodiments according to FIGS. 2 and 8 essentially in that the water outlet 63 is arranged on an edge of the protective cover 64 and extends obliquely with respect to the longitudinal axis of the protective cover 64.
  • the water inlet 65 again runs, as in the embodiment according to FIG. 8, radially with respect to the longitudinal axis of the protective cover 64.
  • the heating element is not shown in detail since it has essentially the same shape and arrangement as in the embodiments according to FIG or 8.
  • a silicone fabric hose 67 is pushed over the ends 66 of the heating conductor, the two ends 66 of the heating element resistor and the fabric tubes 67 are covered with a shrink tube 68 directly on the protective cover 64.
  • FIG. 11 which shows a view of the embodiment according to FIG. 10 from the left, it can be seen that a protective tube 69 for a limiter sensor and a protective tube 70 for a controller sensor are also present in this embodiment.
  • the water inlet 65 and the water outlet 63 can otherwise be constructed similarly to the embodiment according to FIG. 8 or 9.
  • the oblique arrangement of the water outlet 63 has the great advantage that water vapor bubbles forming inside the protective cover 64 as well as air bubbles are easily removed from the protective cover 64 by the flow of water.
  • FIG. 12 shows a schematic longitudinal section through a further embodiment of a protective cover 71.
  • This is also formed in two parts, the lower part 72 having approximately the shape of a flat trough, while the upper part 73 has the shape of a cone.
  • the upper part 73 is substantially larger than the lower part 72, so that the entire protective cover 71 has approximately the shape of a cone.
  • the water outlet 74 is arranged in the region of the cone tip, while the water inlet 75 is arranged at the opposite end of the protective sheath 71 approximately in the middle of the lower part 72.
  • the radiator 76 the ends 77 of which are also led out through the bottom of the lower part 72, is spirally wound to form a cone as well.
  • a protective tube 78 for a controller sensor is arranged on the left side and extends approximately parallel to the lateral surface of the cone.
  • a rotationally symmetrical, approximately mushroom-shaped insert 79 is arranged in the center of the protective cover 71, the outer side 80 of which has the shape of a cone with a rounded tip, while the inner side 81 is curved flat.
  • the cone angle of the outer side 80 is somewhat more acute than the cone angle of the protective cover 71 so that the space between rule the outside 80 of the insert and the inside of the protective cover 71 narrows in the direction of flow. This results in an increasing velocity of the flow due to the decreasing flow cross-section, whereby air or vapor bubbles are torn out of the protective cover 71 through the outlet 74.
  • All embodiments of the electrical device according to the invention have in common that the protective cover causes thorough mixing of the water flowing through and that any water vapor or air bubbles which are formed are entrained by the flow and removed from the protective cover of the instantaneous water heater.
