Definitions
- the present invention relates to a insulated container, in particular in the form a housing for refrigerators and warmers is present, with an inner wall and an outer wall made of a thermally highly conductive material and with an interruption in the thermal connection between inner wall and outer wall.
- the object of the present invention based on specifying a double-walled container, which is sufficiently thermally insulated and yet with not one at the thermal zone boundary broken wall inexpensively and with low assembly effort can be produced.
- the Container characterized that the inner wall and the outer wall in the area a thermal zone boundary in one piece are trained and the interruption of thermal connection between the inner wall and the outer wall is made at least partially by that cross-sectional areas of the inner wall and / or Outer wall are reduced.
- the container is identified by an im Area of the thermal zone boundary in one piece. trained inner wall and outer wall. Through this seamless transition between the inner and the outer wall can be produced in one operation, so that an even more extensive Simplification of the production process and a further reduction in the Manufacturing expenses can be realized.
- the container is characterized by predetermined positions in the walls formed holes, which are in one row or in several Rows are arranged.
- the holes can be in a predetermined grid from each other be spaced.
- This embodiment allows easy editing of the Wall elements by punching, which can be largely automated. By training Holes in one or more rows can provide a sufficient reduction in thermal effective cross-section while maintaining the required mechanical stability be realized.
- the given grid in which the holes from each other are spaced, it becomes possible to suspend the holes according to the invention or fastening of other components such as door hinge, shelves, Struts, seals etc. to use and thus the manufacturing process still to further simplify.
- Figure 1 shows the arrangement known in the prior art with the inner wall 5, the Profile 3 from the thermally poorly conductive material and the outer wall 1.
- the space 7 covered by this arrangement is through an isolator, e.g. Filled with polyurethane foam or glass wool mats.
- Figure 2 shows a cross-sectional view of a wall structure according to the invention.
- the Inner wall 5 and outer wall 1 are integrally formed together.
- holes 9 are punched out in the inner wall 5 and in the outer wall 1 reduce the cross-section of the walls so that the thermal resistance is increased is, so that the energy loss via the temperature bridge is effectively limited.
- the Gap 7, which is bordered by the walls 1, 5, is in a known manner, e.g. With Filled with polyurethane foam or glass wool mats. If necessary, the holes 9 before Isolate e.g. with polyurethane foam, covered with a tape and thus the Prevents foam from escaping.
- the holes 9 are preferably provided in the region of the thermal zone boundary in order to interrupt the temperature bridge as effectively as possible. This way Achieve efficiencies equal to those of interrupting the thermal zone boundary come close to a profile 3 made of a thermally poorly conductive material.
- FIG 3 is a partial spatial representation of a cabinet according to the invention shown.
- the inner walls 5, like the outer walls 1, have holes 9. This Holes 9 can be punched out during processing of the wall plate Manufacture of the inner wall and the outer wall easily manufacture and can in if necessary several parallel rows.
- the holes 9 with one another and the rows of holes with respect to one another can have predetermined distances have, which are chosen so that they can assemble door hinges without drilling allow additional holes 9. Furthermore, the assembly of shelves or striving possible in a simple way. If they have fasteners in the appropriate Have distance, so that clear in the subsequent manufacturing steps Simplification so that savings are possible.
- seals can also be used can be easily attached or replaced when they are on their back Have fasteners in the hole spacing.
- the holes 9 can have the same shape as required: however, they can also differ from each other in shape and / or size. Thus, e.g. triangular, quadrangular, polygonal, round, non-round, elongated and / or of different sizes Holes may be provided to meet specific requirements.
