Definitions

  • the present invention relates to a refrigerator and / or freezer with a heater for preventing condensation.
  • a disadvantage of these known heaters is that refrigerant pipes are expensive and also very expensive to process. For example, there may be pressure points on the outer surface.
  • Another disadvantage is that the energy consumption and thus the energy costs are comparatively high, that it can lead to local overheating and that under certain circumstances an influence on the internal temperature of the device can occur.
  • the present invention is therefore the object of developing a device of the type mentioned in such a way that the formation of condensate can be avoided in a simple manner and relatively inexpensively.
  • the heating device is designed such that it is mounted or attachable to or in the region of at least one outer side, preferably on or in the region of one or both side walls of the device, wherein the heating device according to the invention is not foamed, allowing their more flexible use .
  • the heating device according to the invention is a component of a kit, preferably one retrofit kit, which is only installed on devices where there is a risk of condensation. In this way, a significant cost reduction can be achieved, since it is not necessary to equip all devices with such a heater.
  • the term "on or in the region of the outside” means that the heating device is arranged such that the outside of the device can be heated by the heating device Device housing to be arranged.
  • the heating device is an electric heater.
  • the heating device is a foil heater with welded-on heating wires.
  • tubular heater which can be attached in any form between two devices or the device and a wall or fixed by clamping.
  • a cover of the gap between the devices or between the device and wall can be provided for optical reasons. It can be a panel that covers the gap and thus the heater.
  • the heating device (s) is / are suspended in the area in question. If a connecting element is provided, which connects two devices standing next to each other or a device with an adjacent wall or the like, it can be provided that the at least one heating device is arranged on this connecting element, in particular suspended.
  • the heating device can also be arranged, in particular suspended, on a cover element which covers the gap between two devices or between a device and an adjacent wall or the like on the upper side and / or on the front side.
  • the heating device is fixed to the device by an adhesive connection. It is conceivable that a film heater is glued to the side wall of a device or even on the wall adjacent to the device or other device wall.
  • the heater according to the present invention may be disposed on the outside of the apparatus.
  • the invention also includes the case that the heating device is not arranged directly on the outside, but in the region of the outside, which is e.g. then the case is when the heater is disposed on the wall or device wall adjacent to the device.
  • the device has a connection for the heating device and / or a receptacle for a control or regulating device for the heating device.
  • the connection and / or the receptacle is preferably designed such that retrofitting is possible.
  • Conceivable is thus the use of a kit with heating and / or said control or regulating device and optionally one or more sensors preferably for temperature and / or humidity, the kit can preferably be retrofitted easily and quickly.
  • the refrigerator and / or freezer may include a control or regulating device for controlling the heating device, wherein the control or regulating device may be designed such that it is the heater permanently and operates at a constant power, for example. It is thus conceivable that the heater runs as soon as the device is put into operation. In order to avoid excessive heating of the device, the heating power must be suitably adjusted to the surface on which it is acting.
  • control or regulating device is designed such that it operates the heating device in dependence of one or more parameters.
  • the parameter may, for example, be the temperature at or in the region of at least one outer side of the device. It is possible, for example via a mechanical or electrical thermostat, to measure the temperature at or in the area of the outside of the device, for example on the surface of the device, or in the area between two devices or between a device and an adjacent wall or the like. Depending on this measured value, the heating device can then be switched on and off or adjusted in its performance.
  • the parameter may, for example, also be the difference between the temperature at or in the region of at least one outer side of the device and the ambient temperature.
  • the parameter may, for example, also be the difference between the temperature at or in the region of at least one outer side of the device and the ambient temperature.
  • the parameter "humidity” can be used to regulate or control the heating device. It is conceivable to measure by means of a humidity sensor, the humidity or in the range of at least one outside of the device and / or the humidity of the ambient air and make on this basis a control or regulation of the heater. This procedure also allows an energy-optimized mode of operation of the heater.
  • the present invention further relates to an arrangement with at least one refrigerator and / or freezer and at least one heating device, wherein the arrangement is characterized in that the heating device is arranged in the region of at least one outer side of the device.
  • the heating device therefore does not necessarily have to be part of the refrigerator and / or freezer, but may for example also be fixed to a wall adjacent to the refrigerator and / or freezer and / or have a device-independent power supply and / or control or regulation ,
  • the heating device can be arranged, for example, in the region of one or both side walls of the device.
  • the heating device can be part of a kit which can be attached in the area of the device. It is conceivable to carry out the kit as a retrofittable kit.
  • the refrigerator and / or freezer of the invention is preferably carried out according to the characterizing part of one of claims 4 to 16.
  • the embodiment relates to an arrangement with two juxtaposed refrigerators and / or freezers or an arrangement with a refrigerator and / or freezer, which is placed next to a furniture or building wall.
  • a foil heater is glued to the side wall of the device facing the adjacent device or to the wall.
  • the foil heater is located on the outside of the side wall. Because of your small thickness, the gap to the adjacent device or to the wall can be made very small.
  • the device further comprises a control or regulating device, by means of which the heating device can be controlled / regulated.
  • the device further comprises at least one temperature and / or at least one humidity sensor, wherein the temperature sensor is arranged such that measures the temperature in the gap to the adjacent device or to the wall and / or on the surface of the device outside.
  • the humidity sensor may be arranged to detect the humidity of the ambient air.
  • the control device operates the heating device at a higher power or the relative switch-on duration, ie. the ratio of operating times and times in which the heater is out of service increases. In this way, condensate formation can be effectively and energy-optimized prevented.
  • the heater according to the present embodiment is a retrofittable kit. In order to connect the heater easily to the device, this is carried out with a corresponding plug-in device. Furthermore, the device has a receptacle into which the control or regulating device can be inserted, which serves to control or regulate the heating device. Also, recordings can be provided for one or more sensors that are used for temperature measurement and / or for measuring the humidity. The connection of the control or regulating device and / or of the sensor (s) can also take place, for example, by means of a plug connection, by means of which the mechanical fixing and the electrical connection are provided.
  • the present invention opens up the possibility that not all devices with a heater to avoid condensate formation must be performed at the factory, but only the devices in which, possibly due to their location with a condensation is expected. Additional costs and additional expenses therefore only become effective with these devices and not with all devices.
