Definitions

  • the present invention relates to a household built-in refrigeration appliance with a machine unit suspended below the carcass.
  • Such refrigerators allow the use of a base zone, which is usually present in built-in kitchen furniture between a bottom shelf of the kitchen furniture and the floor by the opening of the refrigerator in this shelf an opening is cut through which engages the machine unit in the base zone of the kitchen cabinet.
  • the space gained by the displacement of the machine aggregate into the conventionally unused base zone can be used to increase the storage space of the refrigeration device or to increase its insulation.
  • Fitted kitchens are available with different height sockets.
  • the height of the machine unit must be kept so low that it also fits in a base zone of low height. In practice, this means that the lowest point of the machine assembly should not be more than 10 cm lower than the footprint of the device body, which comes to stand on the shelf on both sides of the cut in this opening.
  • Object of the present invention is to provide a refrigeration device with a suspended machine unit, in which despite a slight protrusion of the machine unit below the footprint of the device, a conventional rotary-driven compressor is used.
  • a refrigeration device in particular a household built-in refrigeration appliance, with a body, at least one door which encloses at least one storage space with the body and with a suspended under the body machine unit, wherein at the bottom of a bottom of the body a recess is formed, in which engages the machine unit.
  • the machine unit can be built higher than its intended projection below the carcass base. Lateral walls of the floor preferably flank the recess to possibly serve as a stand for the device can.
  • a front edge of the floor can generally not be supported continuously on the bottom plate of a kitchen furniture, since the formed in the bottom plate, the machine unit receiving cutout is usually open to the front edge; however, preferably also the front edge of the bottom is free from the recess to hide the recess from the user.
  • the base area of the recess approximately to the base of the compressor mounted below. Since the bottom of the carcass at its top should be flat for ease of use, but in such a case the cutout would in practice have a height of several centimeters, either in the vicinity of the - heat donating - compressor a very thin layer of insulation would be on the ground the body would result in a significant heat input and condensation on the underside of the floor, or the thickness of the floor would have to be much higher away from the recess than the walls and the ceiling of the body, resulting in losses of usable storeroom volume and To fill the floor - would lead to increased demand for insulation material, without significantly improving the thermal insulation properties of the body. It is therefore preferred that the base of the recess coincides with the base of the machine unit. So at least one can uneconomical enlargement of the volume to be filled with insulating material can be avoided.
  • the ceiling of the recess comprises an area to provide the machinery with the required space at its top.
  • the surface is formed as a flat surface and this plane surface is preferably at least 20 mm higher than the bottom of the soil.
  • the recess has a maximum height above the accommodated in the machine unit compressor. A slight reduction in the insulation material thickness above the compressor can be accepted in the interest of better space utilization.
  • the highest point of the ceiling of the recess should preferably be 40 to 60 mm higher than the bottom of the floor.
  • Fig. 1 shows a section through a combination household refrigerator in the depth direction of his housing.
  • Body 1 and door 2 enclose two storage spaces, such as a normal refrigerated compartment 3 and an underlying freezer compartment 4.
  • a compressor 5 and a in Fig. 1 not shown condenser and a fan are housed in a suspended under a bottom plate 6 of the freezer compartment 4 machine unit 7.
  • the base of the machine unit 7 is slightly smaller than that of the body 1, so that at least lower edges of - outside the cutting plane of the Fig. 1 lying - side walls of the body 1 can come to stand directly on a cut-out shelf 36 of a kitchen cabinet, engages through the cut the machine unit 7 in a base portion 37 of the kitchen cabinet.
  • the machine unit 7 essentially has the shape of a flat cuboid, on the upper side of which a flat dome is formed in order to make room for the compressor 5, the height of which is greater by a few centimeters than that of the cuboid.
  • a recess 8 is formed in the bottom plate 6 of the body, in whose substantially planar ceiling 9 a dome 10 is locally formed for receiving the compressor 5.
  • the bottom plate 6 has a thickness substantially equal to the thickness of the rear wall 11 of the body 1 and its side walls at the level of the freezer compartment 4 corresponds.
  • the bottom plate 6 is flat.
  • the dome 10 leads locally to a weakening of the insulation of the freezer compartment 4, but the height of the dome 10 in comparison to the thickness of the bottom plate 6 on the flat part of the ceiling 9 is not so large that condensation would be feared in the dome 10.
  • the door 2 is provided in a conventional manner with a magnetic seal 12 which abuts the normal cooling compartment 3 and the freezer compartment 4 surrounding the front of the body 1.
  • the distance d3 between a voltage applied to the ceiling plate 13 of the body 1 strand of the magnetic seal and the underside of the ceiling plate 13 is smaller by the height d 1 of the recess 8 than the distance d4 between a voltage applied to the bottom plate 6 strand of the magnetic seal 12 and the top
  • corresponding spacing conditions could be realized even on a door closing only a single storage compartment.
  • Fig. 2 shows a schematic section through a refrigerator, which contains a linear compressor 15 in a suspended machine unit 14 and with sufficient availability of linear compressors, the device of Fig. 1 replace.
  • the outline of the bottom plate 6 of the device Fig. 1 is in Fig. 2 drawn as a dashed outline. Due to the reduced height of the machine unit 14, the recess 8 is omitted, and the top of the bottom plate 6 is - while maintaining their strength - by d1 deeper than the device of Fig. 1 ,
  • the distances d3 and d4 between the magnetic seal 12 and the underside of the ceiling plate 13 and the top of the bottom plate 6 are characterized - in otherwise opposite Fig. 1 unchanged dimensions of the door 2 - the same.
  • the course of a groove on which the magnetic seal 12 is anchored in both refrigerators, the Fig. 1 and that of Fig. 2 the same.
  • the freezer 4 of Fig. 1 contains three pull-out boxes 16, 16, 17, which differ in height, the height of the two upper pull-out boxes 16 by the height d1 of the recess 8 is smaller than that of the lower, higher pull-out box 17.
  • the order Height d1 enlarged freezer compartment 4 of the refrigerator Fig. 2 can be ideally fully utilized with minimal effort by one of the two lower pull-out boxes 16 is replaced by an additional high drawer 17.
  • the door 2 has in a conventional manner to reinforce their insulation layer in the amount of the freezer compartment 4 on a flat projection 18, which - apart from narrow marginal gaps - on the entire height and width of the freezer compartment 4 engages in this.
  • the door 2 could at the expense of a widened gap 19 at the bottom of the projection 18 unchanged in the device of Fig. 2 be taken over.
  • the projection 18 as in Fig. 2 presented in comparison to the door of the Fig. 1 slightly downward to keep the gap 19 between the lower edge of the projection 18 and the bottom plate 6 narrow unchanged.
  • a corresponding correction to the thermoforming tools used for molding the inside of the door requires only little effort, since the course of the magnetic seal 12 receiving groove on the inside of the door does not need to be changed.
  • a step 20 is formed, whose height corresponds to the height of the recess 8.
  • the horizontal surface of the step 20 is at the same height as the top of the bottom plate 6 in the device of Fig. 2 so that when passing from the device the Fig. 4 on the device of Fig. 3 on the door 2 no adjustments are required.
  • Fig. 4 shows a slightly more detailed cross section through the lower portion of a refrigeration device according to the invention.
  • the bottom plate 6 is composed of the bottom surface of a known per se Way deep-drawn inner container 22 of the freezer compartment 4, a molded plastic shell 23 in which the recess 8 and the dome 10 are formed, and between the inner container 22 and shell 23 injected insulating foam 24.
  • Outer plates 25 of the side walls 21 and in Fig. 4 invisible rear wall 11 surround the edges of the shell 23.
  • the lower edges of the side walls 21 are stiffened by a rectangular frame, here along the rear wall 11 and the front edge of the bottom plate 6 interconnected hollow sections 26.
  • the shell 23 can by integrally formed, in the insulating foam 24 engaging ribs 27, in Fig. 4 indicated as a dashed line, be stiffened.
  • the machine unit 7 has a housing composed of two shell-like parts, an upper part 28 and a lower part 29.
  • the upper part essentially serves to protect the installed components, the compressor 5, the condenser 30, the fan 31, possibly an evaporation tray, etc., before the machine assembly 7 is installed in the refrigeration unit.
  • the lower part 29 acts as a carrier for the installed components.
  • the two housing parts 28, 29 have at their lower and upper edge encircling, mutually contacting flanges 32, 33, wherein the flange 32 rests around the recess 8 on the underside of the shell 23.
  • the machine unit 7 is fixed by screws or bolts 34, which in turn pass through a buffer 35, the flanges 33, 32 and the edge of the shell 23 and anchored in the hollow sections 26.
  • the buffers 35 serve as feet which, after installation of the device in a furniture recess, support the device against the cut-out bottom plate 36 of the furniture niche.
