Definitions

  • the invention relates to a refrigerator, in particular a household refrigerator, with a glass door.
  • the glass door comprises a first glass and a second glass, with a glass space between the first and the second glass.
  • the glass door also includes a spacer for the mutual spacing of the first glass and the second glass.
  • the spacer has a rectangular frame shape with four sections, a door handle section, a hinge section, a ceiling section and a floor section.
  • the spacer directly frames the space between the glass and has an inner side of the spacer directed towards the space between the glass.
  • the cooling device further comprises a usable space wall with an inside of the usable space wall directed towards the usable space.
  • the invention also relates to a refrigerator with a glass door which includes a rectangular door frame.
  • Refrigerators designed to store wine bottles often include a glass door. This allows the user to view their wine collection even with the door closed.
  • glass doors with double or triple glazing are regularly provided.
  • Two glasses enclose a glass space in which there is air or another gas, for example a noble gas. These gases have a particularly low thermal conductivity and therefore insulate particularly well.
  • the absence of water vapor in the space between the glass also prevents unwanted condensation in the closed volume between the glass panes.
  • Thermal insulation on the frame of the glass door is more difficult. If the thermal conductivity on the frame is too high, condensation will form there, which is undesirable. This problem becomes greater the higher the humidity in the environment.
  • a refrigerator that is to be used in a tropical climate therefore requires a special design of the glass door frame.
  • the task is therefore to provide a cooling device, in particular a household refrigerator, which is designed to be as suitable for the tropics as possible.
  • a cooling device in particular a household refrigerator, comprises a glass door with a first glass and a second glass.
  • the glass door therefore has at least two glasses, which ensures particularly good thermal insulation of the glass door. In other words, it is at least double glazing, in particular triple glazing.
  • the glass door further includes a spacer, which distances the first glass and the second glass from each other.
  • the spacer has a rectangular frame shape with four sections, a door handle section, a hinge section, a ceiling section and a floor section.
  • the ceiling section corresponds to the upper, horizontally extending section of the spacer
  • the floor section corresponds to the lower, horizontally extending section of the spacer.
  • the door handle section is a vertical section of the spacer which is on the Side of the door on which the door handle is arranged.
  • the hinge section is the vertically extending section of the spacer, which lies opposite the door handle section and is located where the door hinge connects the glass door to the rest of the refrigerator via a hinge.
  • the spacer is often also referred to as an edge seal.
  • the glass door includes a glass space formed between the first and the second glass. Air or another gas, in particular a noble gas, can be admitted into the space between the glass.
  • the spacer closes the space between the two lenses and maintains the distance between the two lenses. It therefore immediately frames the space in between.
  • the side of the spacer that is in contact with the gap is called the inside of the spacer.
  • the cooling device also includes a usable space.
  • the goods to be cooled, especially wine bottles, are stored in this.
  • the usable space includes a usable space wall.
  • the usable space wall and the glass door enclose the usable space.
  • the side of the usable space wall facing the usable space, i.e. towards the inside, is referred to as the inside of the usable space wall.
  • the inside of the usable wall wall and the inside of the spacer When the glass door is closed, the inside of the usable wall wall and the inside of the spacer have a mutual distance of a maximum of 15 mm along the door handle section and/or the hinge section and/or the ceiling section and/or the floor section.
  • the inside of the usable space wall and the inside of the spacer are arranged parallel to one another.
  • a small distance between the inside of the usable space wall and the inside of the spacer means that when the door is closed, the spacer is, if possible, arranged in front of the usable space wall and not in front of the usable space. This means the spacer is in one place in the Glass door arranged, which is in contact with an already well-insulated area of the rest of the cooling device, namely with the usable space wall. Since the spacer is a good conductor of heat compared to the gas present in the space, placing the spacer in front of the wall of the usable space prevents condensation on the glass door as much as possible.
  • a frame heater can be provided in the usable space wall, which also supplies heat to the spacer.
  • the spacer touches the sides of the first glass and the second glass that face the glass gap along the entire frame shape.
  • the spacer is therefore a component that is arranged between the two glasses.
  • the distance between the inside of the usable space wall and the inside of the spacer along the door handle side and/or along the hinge side is advantageously a maximum of 10 mm, in particular a maximum of 5 mm, in particular a maximum of 3 mm.
  • the spacer can be arranged particularly well on the edge of the glass door because there are no other elements, apart from the door handle, on this side of the glass door. So that the spacer on the hinge side can be arranged as close to the edge as possible, the door hinge must be arranged to save space.
  • the inside of the usable space wall is advantageously a flat surface, which extends as a flat surface along the entire depth of the usable space, and/or extends as a flat surface along the entire height of the usable space. Accordingly, the usable space wall, in front of which the spacer is arranged, is not just a simple door stop, but rather the usable space wall, which is designed to be insulating along the entire depth or along the entire height and a has an insulating effect on the spacer.
  • the term “flat surface” refers to a substantially flat surface and does not exclude the possibility that there are formations on this surface for mounting shelves/tray rails or lighting.
  • the inside of the usable space wall is a flat surface and, as a flat surface, it extends over at least 10 cm, in particular at least 20 cm, in particular at least 30 cm, in the depth direction of the usable space.
  • the usable space wall comprises an insulation layer, in particular an insulation foam or a vacuum insulation panel, in particular wherein the insulation layer is arranged adjacent to the inside of the usable space wall and/or is spaced from the spacer by less than 7 cm, in particular less than 5 cm, in particular less than 3 cm is.
  • the short distance between the spacer and the insulation layer means that the spacer is well insulated and condensation on the glass door can be prevented as much as possible.
  • the usable space wall which is not part of the glass door, is spaced from the spacer by less than 5 cm, in particular less than 3 cm, in particular less than 2 cm.
  • the task is to provide a cooling device, in particular a household refrigerator, in which the door can be extremely easily adapted to different door sizes.
  • the cooling device comprises a glass door, the glass door comprising a rectangular door frame.
  • This has four interconnected frame elements.
  • the door frame is not designed in one piece, but consists of at least four frame elements.
  • the four frame elements are two side elements, a ceiling element and a floor element.
  • Such a design has the advantage that the height of the glass door can be changed by replacing the side elements and retaining the ceiling and floor elements.
  • the two side elements are advantageously extrusion profiles, in particular made of plastic.
  • Extrusion profiles are bodies with a constant cross-section of any length. This makes it particularly easy to produce side elements of different lengths and use them on glass doors of different heights.
  • the ceiling element and the floor element are injection molded parts.
  • the four frame elements can advantageously be connected to one another by plugging them into one another. This allows particularly easy assembly.
  • a first cooling device and a second cooling device are also protected, wherein the two side elements of the first cooling device and the two side elements of the second cooling device are of different lengths, and the ceiling element and / or the base element of the first cooling device and the second cooling device are designed identically.
  • the Fig. 1 shows a front view of a refrigerator designed for storing wine bottles.
  • the refrigerator is shown as it would be arranged in an installed situation.
  • the glass door 1 is visible with a door handle 2.
  • the glass door 1 can be opened by pulling the door handle 2 and the glass door 1 rotates around hinges which are arranged on the right side of the glass door 1.
  • This is the case with the refrigerator Fig. 1 the left side is called the door handle side, the right side is called the hinge side, the top side is called the ceiling side and the bottom side is called the floor side.
  • Handleless versions are equally possible.
  • the structure of the glass door 1 is based on the sectional view AA Fig. 1 explained in more detail.
  • the glass door 1 comprises a first glass 3, which is arranged on the front of the glass door 1, and a second glass 4, which is arranged on the inside of the glass door 1 is.
  • the two glasses 3 and 4 are spaced apart from one another by means of a spacer 5.
  • the spacer 5 is arranged between the two glasses 3 and 4 and touches the respective insides 3a, 4a of the two glasses 3 and 4. In the case of triple glazing, two spacers 5 are required.
  • the middle glass is preferably arranged centrally.
  • the spacer 5 and the two glasses 3 and 4 enclose a glass space 6.
  • This glass space 6 is filled with a transparent medium, for example with dry air or with a noble gas.
  • the spacer 5 frames the glass space 6 directly, i.e. it is in direct contact with the medium filled into the glass space 6. That side of the spacer 5 which is directed towards the space between the glass and is therefore in contact with the filled medium is referred to as the inside of the spacer 7.
  • the spacer 5 extends along the entire circumference of the two glasses 3 and 4. It forms a rectangular frame shape, as shown by a dashed line in the Fig. 1 is shown schematically.
  • the rectangular spacer 5 comprises four sections, namely a door handle section 5a, a hinge section 5b, a ceiling section 5c and a floor section 5d.
  • the glass door 1 closes a usable space 8 intended for storing cooling objects, which is delimited by a usable space wall 9.
  • the usable space 8 is thus completely enclosed by the usable space wall 9 and the glass door 1.
  • a magnetic door sealing element 11 is provided on the contact surface 10 between the glass door 1 and the usable space wall 9. It ensures that the transition from the glass door 1 to the usable space wall 9 is thermally insulated as well as possible.
  • the side of the usable space wall 9 directed towards the usable space 8 is referred to as the inside of the usable space wall 12.
  • the usable space wall 9 includes one Inside of the useful space wall 12 adjacent insulation layer 17, which consists of an insulation foam. Alternatively, the insulation layer could also be a vacuum insulation panel or a composite of a vacuum insulation panel and an insulation foam.
  • the inside of the usable space wall 12 is a flat surface which extends along the entire depth T of the usable space 8.
  • the spacer 7 is arranged mainly in front of the usable space wall 9 and therefore as close as possible to the edge 1a of the glass door 1.
  • the spacer inside 7 is therefore only spaced from the inside of the usable space wall 12 by a distance A of 2 mm. If the distance A were larger, the spacer 5 would overlap more with the usable space 8 and less with the usable space wall 9.
  • condensate water would preferably form on the outside of the first glass 1, namely at the location where the spacer 5 is arranged, in a humid climate. Because the spacer 5 would form a thermal bridge between the moist environment and the cold usable space 8, thereby keeping the outside 3b of the first glass 3 particularly cool and thereby causing the formation of condensation.
  • such condensation formation is prevented or at least reduced due to the small distance A.
  • the spacer 5 Since the spacer 5 is largely arranged directly in front of the usable space wall 9, it forms only a very slight thermal bridge between the usable space 8 and the surroundings. In other words, the thermal bridge of the spacer 5 is isolated from the usable space wall 9. Furthermore, a frame heater 16 can be placed in the usable space wall 9, which enables a moderate heat input to the magnetic door sealing element 11 and consequently further to the spacer 5.
  • the distance E between the spacer 5 and the insulation layer 17 is only 22 mm and the distance F between the spacer 5 and the usable space wall 9 is only 11.5 mm large. These short distances also contribute to the spacer 5 being insulated as well as possible and, if possible, not forming a thermal bridge between the usable space 8 and the moist environment.
  • the distance A between the inside of the spacer 7 and the inside of the usable space wall 12 is shown along the door handle section 5a of the spacer 5.
  • the sectional views BB, CC and DD illustrate the respective distances along the hinge section 5b, along the ceiling section 5c and along the floor section 5d.
  • the two glasses 3 and 4, the spacer inside 7 and the usable space wall inside 12 are each marked by reference numbers for better understanding.
  • the Figs. 2 and 3 show the glass door 1 with a view of the back, ie the side that faces the usable space 8.
  • the glass door 1 comprises a rectangular door frame 13, the first glass 3, the second glass 4 and the frame-shaped spacer 5.
  • the door frame 13 has four interconnected frame elements, namely a ceiling element 13a, a floor element 13b and two side elements 13c.
  • the two side elements 13c are designed as extrusion profiles made of plastic, i.e. they have an identical cross section along the entire length.
  • the ceiling element 13a and the floor element 13b are plastic injection molded parts.
  • the ceiling element 13a and the floor element 13b each have extensions 14, which can be inserted into openings 15 of the side elements 13c. This means that the four elements of the door frame 13 can be inserted into one another.
  • the Fig. 3 shows a glass door 1, which compared to the glass door 1 of Fig. 2 has shorter side elements 13c.
  • the ceiling element 13a and the floor element 13b are in the glass doors 1 Figs. 2 and 3 identically designed. This simplifies the production of glass doors 1 of different heights because the ceiling element 13a and the floor element 13b are always identical and only the length of the side elements 13c needs to be adjusted.
