Definitions

  • the invention relates to a device for attaching at least one in a container for receiving a liquid to be heated protruding Heating device in an opening of the container wall according to the preamble of Claim 1.
  • the fastening bolt a hammer - like head, which after passing through the in the wall of the container provided opening is pivoted by 90 ° and then abuts the opening edges.
  • a Clamping plate with the bolt a one-piece unit.
  • a device is also known from EP-A-O 157 277 and EP-A-O 275 635 in which a sensor device protruding into the interior of the container is provided, which comes into contact with the tubular heater itself.
  • DE-A-25 52 625 describes a device for attaching a heating device in a container in which no sensor device is provided.
  • the flange plate used here has three continuous Breakthroughs, two for the connection ends of a tubular heater serve and another for the fastener.
  • a device can for example in a dishwasher, a washing machine or the like. be used.
  • DE-GM 19 68 234 has therefore already proposed the number of to reduce the necessary openings in the container wall, that in the flange plate next to the openings for the two tubular heater ends and a further continuous opening for the fastening device is provided, into which a pipe section is inserted.
  • This Pipe section is closed to the inside of the container and serves to accommodate one Sensor and / or control device that the heating device in the event of overheating switches off.
  • this proposal has the disadvantage that for the flange plate a corresponding minimum size must be provided and that on the flange plate another opening to be sealed must be arranged. Straight in cases where the flange plate is small by its geometric dimensions should be or where high demands are made on the tightness this solution is disadvantageous.
  • the fastening device already has an opening in the flange plate must be provided is achieved by the proposed solution that when installing a sensor and / or control device initially no further Breakthrough becomes necessary. This not only allows the use of an in their geometrical dimensions relatively small flange plate, but this also simplifies the processing of the flange plate.
  • the heating device to the cavity having element of the fastening device or this element to the Heating device is introduced or both touch or even with each other are connected.
  • this possibility also exists with one Cavity element of the fastener when this with the boundary surface of the fastening device pointing into the interior of the container completes. This can happen, for example, that the Heating device brought up to the fastening device with a section and by means of this section in the vicinity of that having the cavity Elements touches the fastening device or is attached to it there.
  • the cavity can both into the inside of the container as well as outwards or only outwards be open.
  • the first option can be used, for example, if the sensor and / or control device or parts of it in its own Housing are arranged. If the housing is to be dispensed with, the Cavity of the fastener element towards the interior of the container must be completed, so that only the element of the fastening device must be sealed when it passes through the flange plate.
  • a wide variety of embodiments can be used for the fastening device Find use.
  • a particularly simple construction is achieved in that the fastening device by a holding device arranged in the interior of the container or clamping plate and a clamping device is formed.
  • the tensioning device can be arranged by an approximately centrally on the clamping plate and be formed with this fixed bolt, which by a Breakthrough of the flange plate passes through and on the outside of a nut for fixing the fastening device and for tightening the flange plate can be screwed on.
  • the clamping plate can then be turned in by turning the lock nut
  • the direction of the flange plate are moved and thus possibly between the Flange plate and the clamping plate arranged sealing plate between them clamp and at the same time the flange plate against the outside of the Tension the container wall.
  • a Fastening device constructed in this way, or any other, of the Is operated from the inside of the container especially if one Accessibility from the outside after the final assembly of the invention Device receiving total apparatus, such as a dishwasher, not possible.
  • the Components or assemblies described above from the inside to the outside.
  • the fixation of the sensor and / or control device or parts of it in Interior of the cavity of the element of the fastening device can on the happen in many different ways.
  • a sensor and / or control device is provided is.
  • several parameters such as the temperature of the liquid and regardless of that Temperature of the heating device, it may be necessary to add further sensor and / or to provide control devices.
  • the attachment of these additional Sensor and / or control devices can be done in different ways. So it is possible on the one hand that the fastening device two or more Flange plate penetrating or penetrating elements, each with at least has a cavity, the arrangement of the elements, for example, in Form a flange screw can be done. In such a case, anyone can the elements of the fastening device one of the above Have training.
  • the heating device can be formed by a wide variety of heating elements.
  • the heating device can be a preferably electric tubular heater be with two connection ends, for each of which an opening in the Flange plate is provided.
  • the heater has a relatively large surface area.
  • the heater inside the container one, essentially W-shaped shape with two connection ends, the openings arranged for the connection ends in the region of the edge of the flange plate and the opening for the fastening device and for the existing further sensor and / or control device between the openings are provided for the connection ends of the heating device. It can the middle section of the W-shaped tubular heater to the cavity having element of the fastening device be brought up, so for example, to enable the temperature of the heating device to be monitored.
  • the heating device essentially forms a loop with two connection ends, that the openings for the connection ends on one side of a substantially central plane of the flange plate running perpendicular to the flange plate are arranged that at least part of the closer to the center plane located portion of the inside of the container part of the Heating device outside of through the two connection ends of the heating device spanned plane runs and intersects the middle plane and that the possibly existing further sensor and / or control device on the other side of the Center plane is arranged and at least partially the center plane intersecting section of the heater covered.
  • the arrangement of the openings on the flange plate can be very different respectively.
  • the central longitudinal axes of at least two openings lie in one plane.
  • the flange plate can also have a wide variety of shapes. she can for example, have an essentially oval shape. In this case it is from Advantage if the center of the openings in the area of the flange plate on the main axis of the ellipse given by the oval shape of the flange plate lie. As a result, despite a relatively large number of openings these are arranged in a clear form and close together.
  • a separate sealing device For sealing the opening of the container wall provided for the heating device through the flange plate can be next to the flange plate, if necessary with its own Sealing elements is provided, a separate sealing device be provided. There is a possibility that between the flange plate and the fastening device, a sealing device is provided, which Seals the opening in the container wall when the flange plate is inserted.
  • the Sealing device can also be formed by a wide variety of elements be. It is particularly advantageous if the sealing device passes through the edges the flange plate may have protruding openings for the heating device, the fastening device and any further sensor and / or Control device having plate is formed.
