Definitions

• the present invention relates to a slide rail for a wire tube evaporator, an arrangement of a slide rail and such an evaporator and a refrigeration device equipped therewith.
• a wire tube evaporator is conventionally constructed of an in-plane meandering tube for a refrigerant and a plurality of wires connected thereto at a plurality of points above or below the tube, on the one hand, for a mechanically stable, rigid assembly on the other hand, to increase the effective heat exchange surface area of the evaporator.
• Such wire tube evaporators are used in particular in freezers, where they are each arranged in planes between two Gefriergut electern to effectively cool their contents.
• these frozen food containers are mounted in the smallest possible vertical distance from the wire tube evaporator.
• the frozen food containers When fully loaded, there is a possibility that the frozen food containers will bend slightly, which may result in the bottom of a frozen food container touching the underlying wire tube evaporator.
• the frozen food container When the frozen food container is pulled out, it dribbles over the evaporator, which can lead to abrasion and premature wear.
• this is the rear, facing away from the door of the refrigerator edge.
• the number of parallel pipe sections within the evaporator extending between it and the opposite edge is necessarily straight.
• the tube sections of the evaporator are evenly distributed over the width thereof, there is either no tube section extending along a center line of the evaporator from the rear wall to the door of the refrigeration device, or the distribution of the tube sections in the width direction of the evaporator is asymmetrical.
• two slides must be arranged symmetrically, because if only one slide is located away from the center, this causes a sideways twist when pulling out and pushing in the frozen goods and thus the risk that it gets stuck.
• the object of the present invention is to provide a slide rail for a wire tube evaporator, which can be placed exactly along a center line of the evaporator, even if no section of the refrigerant tube of the evaporator extends along this center line.
• the laterally projecting arm allows the attachment of the slide with a basically any, the arm length corresponding lateral offset with respect to the pipe section to which the pipe clamp is attached.
• a slide rail may, in principle, be suitably provided for any arrangement of the refrigerant tube in the wire tube evaporator so as to extend along the center line of the evaporator.
• at least two arms with pipe clamps attached thereto are provided.
• These arms are preferably mounted on a same longitudinal side of the rail body. This allows the use of a same slide for wire tube evaporator, in which the distances between parallel pipe sections differ slightly, or if the distance between parallel pipe sections due to production, this does not result in such an arrangement of the arms to a skew orientation of the slide with respect to the midline.
• a hook is preferably arranged on the rail body with an insertion gap open in the longitudinal direction of the rail body, which accommodates a wire of the evaporator and the rail body so can be supported on this wire in the direction of the tensile or shear force.
• a wire clip may be arranged with an insertion gap open transversely to the longitudinal direction of the rail body for insertion of a wire of the evaporator on the rail body.
• both the hook and the wire clip are provided on opposite longitudinal ends of the rail body, respectively, so that the slide rail can be conveniently mounted by first placing the hook on a wire of the evaporator and then folding the rail body against the evaporator and clamping the wire clamp onto a wire second wire is attached.
• the rail body and the at least one arm are preferably molded in one piece from a plastic.
• the invention also provides an arrangement of a wire tube evaporator and at least one slide, as defined above, and a freezer with such an arrangement.
• FIG. 1 is a perspective view of a slide rail according to the invention from above.
• Fig. 2 is a perspective view of the slide rail from below;
• Fig. 3 is a schematic section through a refrigeration device in which an equipped with slides according to the invention wire tube evaporator can be seen from above.
• Figs. 1 and 2 The structure of the slide is first with reference to Figs. 1 and 2 described.
• the free cross-section of the pipe clamp 3 is suitably dimensioned to positively encompass a refrigerant pipe of a wire tube evaporator, which will be discussed in more detail in connection with FIG. 3.
• top of the arms 2 is slightly lower than the top of the rail body 1, so that in a sliding away a frozen food container over the top of the rail body 1 no risk of sticking of the frozen food at the transversely to the longitudinal direction of the rail body 1 extending edges the arms 2 consists.
• the arms 2 are respectively stiffened by downwardly projecting webs 5, which give the arms 2 in its central region, between the rail body 1 and the pipe clamp 3, a T-shaped cross-section.
• the thickness of the crossbar of the T which also corresponds to the thickness of the arm 2 in the region of the opening 4, is equalized to the diameter of the wires of the wire tube evaporator, so that the arm 2 does not protrude above it between two wires of the evaporator between which it extends in the assembled state; the height of the stiffening web 5 can be significantly greater, since this engages after installation in a free space of the wire tube evaporator.
• each means for fixing the rail body to the wires of the wire tube evaporator are arranged.
• These means consist on the one hand of a wire clamp 6 with two pairs of opposing tongues 7, which correspond in structure and function to the tongues of the pipe clamp 3, and which are adapted only in their dimensions to the plugging onto a wire of the evaporator.
• a hook 8 is integrally formed as a means for fixing the rail body.
• the hook 8 has a rail body 1 parallel to the free end portion 9, which limits an open towards the end of the rail body 1 receiving gap for a wire of the wire tube evaporator.
• the gap 10 is here open towards the end of the rail body 1; However, it could also be opposite, with the center of the rail body 1 facing opening to be oriented.
• a hole opposite the free end portion 9 in the rail body 1 allows molding of the rail body 1 and the hook 8 with only two rigid molds.
• the attachment means could also include more than one hook or clip at each end of the rail body; it could also be provided only wire clips at both ends of the rail body.
• Fig. 3 shows a schematic horizontal section through a refrigerator with a wire tube evaporator 11, which is equipped with three slide rails 12 according to the invention.
• the wire tube evaporator 11 has a refrigerant pipe 13 with a total of six parallel to a center line M of the refrigerator from a rear wall of the refrigerator to the door opening extending pipe sections 14.
• the pipe sections 14 are interconnected by a plurality of transverse to the center line M oriented wires
• the arrangement of the refrigerant piping 13 is symmetrical with respect to the center line M, so that along the center line M none of the parallel pipe sections 14 extends. Instead, one of the three slide rails 12 is arranged along this center line M. It is held by means of its wire clamp 6 and the hook 8 to the wires 15 in the forward-backward direction and anchored by the pipe clamps 3 also in the transverse direction.
