Definitions

  • the present invention relates to a cooling and/or freezing appliance with a body in which a cooled interior is located, and with a locking element pivotably arranged thereon for closing the cooled interior, wherein a consumer is located in the locking element and wherein a line is provided which leads from the body to the consumer.
  • a display in the doors of refrigerators and/or freezers, for example, which shows data to the user and enables operation of the appliance.
  • a cable runs between the door or between the component located in the door and the appliance body.
  • a cooling and/or freezing appliance in which a cable housing is provided in which a cable section is arranged in the closed position of the locking element, wherein a length of the cable section in the cable housing in the open position of the locking element. is smaller than the length of the cable section in the cable housing in the closed position of the locking element.
  • the disclosure relates to a refrigerator and/or freezer in whose door a component is provided which is connected fluidly and/or electrically to at least one component on the body by means of a line, wherein the door is hinged to the body by means of a multi-joint hinge and the line is laid in the form of an arc in a housing such that the line can be pulled out of or pushed into the door or the body.
  • a disadvantage of the known devices is the comparatively complex design of the components necessary for cable routing, as well as the problem that the cable may get stuck or jammed when the locking element moves from the open to the closed position and is not reliably moved into its intended position.
  • KR 2018 0124454 A and WO 2021/129150 A1 reveal further relevant state of the art.
  • the present invention is based on the objective of further developing a cooling and/or freezing appliance of the type mentioned above in such a way that the routing of the cable between the body and the locking element is as simple as possible.
  • This objective is achieved by a cooling and/or freezing appliance with the features of claim 1.
  • the cable is provided to have a covering, either partially or completely, in the form of a fabric hose or a spiral spring.
  • This type of cable design offers the advantage of a particularly low coefficient of surface friction, resulting in superior sliding properties compared to conventional sheathed cables. Consequently, the cable according to the invention slides very easily, i.e., with minimal resistance, on surfaces, effectively preventing snagging or "catching" of the cable with simple means. This excellent sliding property is particularly important This is advantageous if the pipe has to move, for example, in an axial direction relative to other components.
  • the invention encompasses variants in which the fabric tube or the spiral spring is not rigidly connected to the conductor(s) or wires contained therein, i.e., the conductor(s) or wires can move relative to the fabric tube or the spiral spring. According to the invention, there is no rigid connection between the fabric tube/spiral spring and the conductor(s). This variant is more flexible and represents an embodiment of the invention within the scope of the present invention.
  • the line according to the present invention can be a line for data and/or power transmission, such as for power supply.
  • the pipe can also be any other type of pipe, such as a fluid-carrying pipe.
  • a fiberglass tube is used as a sheathing.
  • This woven tube fulfills the requirements for good sliding properties especially well.
  • Cables with sheath insulation are known from the prior art, in which several individual conductors are brought together and held together with a sheath insulation.
  • individual conductors are bundled together in a fabric sleeve and/or in a spiral spring.
  • This routing of several individual conductors in a spiral spring or in a fabric sleeve, in particular a fiberglass sleeve, is more flexible with regard to the bending radius, i.e., smaller bending radii can be achieved than with sheathed cables.
  • the sheathing is designed as a fabric tube or spiral spring
  • the diameter of the composite system consisting of sheathing and cable is smaller; the cable is therefore thinner and more compact than known cables.
  • the composite i.e., the cable used according to the invention, is compressible, meaning it can expand into a different dimension under pressure.
  • the invention has the advantages of small dimensions, flexibility in all bending directions, and the ability to completely cover or enclose all individual conductors.
  • the conductor according to the invention has the sheathing as a fabric tube or spiral spring over its entire length and/or its entire circumference or over a part of the length and/or circumference.
  • one or more hinges are provided by means of which the locking element is pivotably arranged on the body and the cable runs along the hinge in certain areas, wherein the hinge is a multi-joint hinge.
  • the present invention enables a compact solution for routing cables from the device body to the door or other locking element, particularly in devices with multi-joint hinges.
  • the cable according to the invention can carry more than two cables or conductors. These can serve for power and/or data transmission. Preferably, it involves the simultaneous routing of a bus system and power cables to the door.
  • the conduit according to the invention has a compact design, so that both a uniform platform construction can be implemented and the largest possible cooling volume can be provided.
  • the refrigerator and/or freezer according to the invention is preferably a built-in appliance. However, freestanding appliances are also included in the invention.
  • the cable is fitted with a connector at one or both ends. This allows for easy cable replacement.
  • the cable according to the invention is designed with multiple conductors and preferably has more than two conductors.
  • the number of conductors is four to eight, for example six.
  • the line can have one or more conductors for power transmission to the consumer and/or for data communication with the consumer.
  • consumer is to be understood broadly and includes any electrical and/or electronic devices, but also, for example, an ice or water dispenser that is supplied with water via the pipe.
  • the present invention further relates to a cooling and/or freezing appliance with a body in which a cooled interior is located, and with a locking element pivotably arranged thereon for closing the cooled interior, wherein a consumer is located in the locking element and wherein a line is provided which leads from the body to the consumer, wherein the line is located at least partially on the outside of the body and no housing for receiving the line is provided.
  • the outside is preferably the top of the body.
  • the cable runs in a loop shape in one section, with this section being located on the outside, in particular on the top of the body.
  • the section of the loop-shaped cable run is preferably longer when the door is closed than when the door is open. It is conceivable that the cable could be routed in such a way that no loop is present when the door is open.
  • a force application element in particular a spring, may be provided which is designed to move the aforementioned section of the cable into its loop-shaped form when the locking element is closed. This ensures with particular reliability that the cable preferably moves automatically into its intended position when the door or other locking element is moved from the open to the closed position.
  • the desired restoring force for forming a loop is generated by the sheathing itself.
  • the line is partially or completely covered with a fabric hose or spiral spring.
  • Figure 1a shows a cable according to the invention.
  • the cable or conductor (10) has a covering or sheathing 20 in the form of a fabric tube or a spiral spring. Preferably, it is a fiberglass tube.
  • Figure 1 shows the hinge-side front section of the body K1 of a refrigerator and/or freezer according to the invention.
  • Figure 2 shows the front, hinge-side side section of the appliance body.
  • the door is pivotally attached to the body by means of the multi-joint hinge 40.
  • the reference symbol O designates the top of the device and thus also the body.
  • the cable is connected to the housing via connector 30a, and thus to a unit located within it, such as a power and/or data supply, a control or regulation unit, etc.
  • Connector 30b connects the cable to a line in the door that leads to a device located in the door.
  • the cable forms a loop-shaped section S that rests freely on the surface O of the body.
  • No housing for cable guidance or cable retention is provided. Due to the inventive properties of the cable, its sliding resistance relative to the surface O is very low. Accordingly, the probability of the cable becoming caught when the door is closed, etc., is very low.
  • the cable is fixed or guided at several points on the multi-joint hinge 40, so that it always runs on the top of the hinge.
  • the cable is pre-tensioned in a direction towards the rear, i.e. towards the back of the device, e.g. with a spring, in the depth direction of the device.
  • Figure 4 shows the cable routing over hinge 40 in the closed state and Figure 5 shows the cable routing over hinge 40 with the hinge open.
