Definitions

  • the invention relates to a method for arranging an evaporator on a container of a refrigerator and / or freezer.
  • a preferred embodiment of the invention consists for example in that the container is designed box-shaped and that the four side walls are pulled together towards the container interior and then the preferably designed as a box evaporator evaporator is pushed.
  • the inventively used evaporator is preferably carried out closed, d. H. limited in the said space or the recess in the circumferential direction in full.
  • the container is made in one piece, d. H.
  • the container without separation point consists of one piece.
  • the first in step a) retracted wall in Direction of container interior, ie outward, is moved. If, for example, opposite walls of the container are pulled together, ie, their spacing is reduced, it can be provided accordingly that after the evaporator has been pushed on, the corresponding walls are pushed out again so that they are preferably in their original arrangement.
  • a further embodiment of the invention consists in that the movement of the at least one wall in the direction away from the container interior takes place such that the container subsequently completely or largely again has the dimensions which it has before the movement of the wall according to step a) according to claim 1 held.
  • the container has one or more side walls, in particular is designed box-shaped, wherein it is in the moving according to step a) according to claim 1 wall is a side wall.
  • the evaporator on its side facing the recess and / or if the container in the region in which the evaporator is to be mounted an adhesive, in particular an adhesive tape or an adhesive coating, the / after the Mounting the evaporator on the container both components, ie glued the evaporator to the container.
  • an adhesive in particular an adhesive tape or an adhesive coating
  • the container is designed box-shaped and that the adhesive is arranged on the outside of one, several or all side walls of the container and / or on the in the assembled state of the evaporator to these adjacent inner surfaces of the evaporator.
  • an embodiment of the invention is conceivable in which the inner surfaces defining the recess of the evaporator are provided with adhesive tape or an adhesive coating, the side wall (s) of the container being retracted before the evaporator is pushed on, ie in the direction of the interior of the container are moved, the evaporator is pushed and then the side wall (s) then back to their original Arrangement are moved so that the adhesive connects the container with the evaporator.
  • the container may have one or more side walls, in particular be box-shaped, and the adhesive may be arranged on the outside of one, several or all side walls of the container and / or on the evaporator in the mounted state of these adjacent surfaces of the evaporator.
  • the edges thus remain adhesive-free, whereby the sliding of the evaporator, the dimensions of the recess can only be slightly above the outer dimensions of the container, greatly facilitated.
  • another embodiment of the invention may be that the dimensions of the recess defined by the evaporator are only slightly above the outer dimensions of the container when its walls are not moved inwardly or outwardly. It is conceivable, for example, that the preferably designed as a plastic container container is only slightly smaller than the recess of the evaporator. The distance may be, for example, in the range of 1 to 2 mm.
  • the evaporator may be a wound box evaporator, which is designed to be closed and limits the said recess in its entirety.
  • the shape of the container and the evaporator is not limited to a box shape. In principle, other designs are conceivable.
  • the container is designed open on one side and has a bottom and one or more associated with this side walls.
  • the container may for example be designed box-shaped or have curved side walls. In principle, it is therefore also conceivable that the container is round, oval or designed such that it has both straight and curved side walls.
  • the container has at least two mutually tapered walls. It can be provided that some or all of the oppositely arranged walls converge towards one another and, in particular, run conically.
  • the container may thus be designed in such a way that the distance of the side walls from one another decreases from the open upper side of the container to the container underside. In principle, it is also conceivable that the distance of the walls from the bottom of the container to the top of the container decreases. The container can thus taper towards the container bottom or towards the open side.
  • the container is the inner container of a freezer compartment of the device.
  • the container has one or more side walls, in particular box-shaped and that according to step a) according to claim 1, one, several or all side walls of the container are moved to the container interior.
  • the movement of the at least one wall takes place in that it is drawn to the container interior.
  • the at least one wall of the container For the purpose of movement of the at least one wall of the container can be provided that it is placed over a mounting core having means by which one, several or all walls of the container to the container interior can be moved.
  • the means comprise vacuum suckers, which can be applied to the walls of the container and by means of which a negative pressure between the walls and the vacuum cups can be generated, wherein the vacuum cups are arranged longitudinally displaceable in order to move the container walls associated with them enable.
  • the vacuum cups are moved after placing the container on the mounting core to the container walls, that then the vacuum is generated and the vacuum cups are then withdrawn, so that the container walls accordingly inward, d. H. bend in the direction of the container interior.
  • the container has a bottom into which the walls pass and an edge region which is formed by the edges of the walls facing away from the bottom, wherein the method comprises the further steps that the container is preferably clamped with its edge is, and then applied to the ground, starting from the container interior an outward force.
  • This ensures that even the edges of the container connecting the side walls are drawn slightly inwards, which further facilitates the assembly of the evaporator.
  • this method is not limited to box-shaped evaporator or container. Other shapes, such as curved walls having containers that have no such edges, can be used.
  • the container interior is placed under vacuum in such a way that, due to the applied vacuum, there is a movement of one, several or all walls towards the interior of the container.
  • a vacuum-setting of the container may, for example, be such that air is removed from the container interior via the open container side, i. such a vacuum is applied that the container walls are turned inwards, i. move towards the container interior.
  • the container may be mounted on a mounting core.
  • the container is made in one piece. Preferably, it is a one-piece plastic container.
  • the evaporator can be designed such that it completely or largely surrounds the recess and it can be designed to be closed in particular in the circumferential direction.
  • a preferred embodiment of the invention provides that the evaporator is designed as a wound box evaporator.
  • the invention further relates to a refrigerator and / or freezer with one or more evaporators, which are mounted according to one or more of claims 1 to 19 on a container of the device. It when the container is a one-piece container, preferably around the inner container of the freezer compartment of the device is particularly advantageous.
  • the container is box-shaped and open on one side.
  • the evaporator is preferably a wound box evaporator.
  • connection between the container and the evaporator is generated by an adhesive, preferably by an adhesive tape.
  • FIG. 1 shows a perspective view of a box evaporator mounted with the method according to the invention.
  • FIG. 2 shows the mounting core for carrying out the method according to the invention.
  • the inner container 10 of a freezer compartment of a freezer or a refrigerator-freezer combination can be seen, on which the wound box evaporator 20 is applied by the method according to the invention.
  • the inner container 10 is box-shaped and has outer dimensions that are only slightly above the inner dimensions of the recess formed by the box evaporator 20.
  • the components shown in Figure 1, d. H. the container 10 and the evaporator 20 communicate with each other by means of an adhesive tape or adhesive coating applied on the insides of the walls of the evaporator 20 prior to mounting the evaporator.
  • the container 10 is a one-piece plastic part.
  • FIG. 2 shows the mounting core, which is used to carry out the method according to the invention.
  • the mounting core has four columns 30, over which the container is slipped with its open side, so that the bottom of the container is at the top and the edges lie on its inside against the columns. Of the four columns, only three are shown in FIG.
  • the fourth pillar is located from the viewer's perspective on the right rear.
  • the columns 30 are slidably arranged so that their position can be changed according to the dimension of the containers.
  • plate-shaped vacuum cups 40 of which two in each case on the shorter sides of the container to be pushed and four are arranged on the longer sides of the réelleschiebenden container, as is apparent from Fig. 2.
  • the suckers 40 After slipping the container over the mounting core of FIG. 2, the suckers 40 are moved up to the insides of the side walls of the box-shaped container, d. H. they exercise a corresponding stroke. Subsequently, the vacuum generation takes place, whereby the vacuum cups 40 abut against the insides of the side walls of the container. The vacuum cups 40 then perform a stroke of, for example, 5 mm inwardly, by means of which the side walls of the container are inwardly, d. H. are retracted arcuately to the container interior or to the mounting core, while the edges of the container supported on the columns 30.
  • the box evaporator can be pushed over the four supported edges of the container.
  • the box evaporator is on its inside, d. H. coated on the side directed towards the recess formed by this recess.
  • this coating is not located in the edge areas of the box evaporator, i. H. in the areas connecting the side walls of the box evaporator. In this way it is prevented that before the complete sliding of the evaporator is already a bonding with the edges of the container.
  • the evaporator Due to the retracted side walls of the container, the evaporator can now be pushed without the adhesive surfaces touching the container. Now move the vacuum cups back out, for which a corresponding stroke is made, the vacuum is released and the container is bonded due to the adhesive inner coating with the evaporator.
  • an adhesive for example an adhesive tape, on the outside of the side walls of the container.
  • it may also be provided to bias the container downwardly at its lower edge and to push upwardly the rear wall of the container located above to also draw inwardly the edges of the container, thereby further delaying the evaporation of the evaporator is relieved.
  • the present invention enables the assembly efficiently working evaporator on inner container of refrigerators / freezers preferably by positive sliding and is relatively easy to carry out. If an adhesive tape is used, there is the advantage that, on the one hand, a good quality of the bond is achieved and, on the other hand, short cycle times can be achieved, since no setting time, as with liquid adhesives, has to be awaited.
