Definitions
- the invention relates to a refrigerator according to the preamble of claim 1.
- Refrigerators are usually equipped with a refrigerant circuit having a compressor, a condenser and an evaporator.
- a refrigerant circuit having a compressor, a condenser and an evaporator.
- the refrigerant heated by the compression cools and thereby changes to the liquid state.
- the refrigerant expands in the evaporator, entering the gaseous state and rapidly cooling down.
- the refrigerant can in this way absorb heat from the interior and dissipate through the condenser to the outside.
- a controller is provided, which is connected to a temperature sensor. Usually, the temperature of the coolant in the evaporator is measured. For this purpose, the temperature sensor is attached to the evaporator.
- the invention has for its object to improve the control behavior of a refrigerator and to reduce energy consumption.
- the object is achieved according to the invention by a refrigerator with the features of claim 1.
- the shield which prevents the contact between the temperature sensor and the refrigerated and / or frozen material causes, even at fully loaded denem refrigerator, only the temperature of the refrigerant in the evaporator is measured. Direct contact between the temperature sensor and the stored cooling and / or frozen goods is reliably prevented.
- the invention does not matter which type of refrigerator is used in the refrigerator.
- the invention is equally applicable to a refrigeration device using a Peltier element.
- the invention is applied to a refrigerator with evaporator.
- the evaporator itself forms the shield for the temperature sensor.
- the temperature sensor is preferably attached to the side facing away from the cooling and / or frozen goods side of the evaporator.
- the evaporator itself acts as a shield and prevents the food to be refrigerated and / or frozen from coming into contact with the temperature sensor.
- the inside of the inner shell of the refrigeration device is provided with a groove.
- This groove is shielded by the evaporator and receives the temperature sensor.
- the temperature sensor is thermally shielded from three sides by the inner shell and the surrounding insulating foam. At the only open side of the groove is located at a small distance from the evaporator. In this way, a shield against the stored frozen and / or frozen is achieved while ensuring that the temperature of the refrigerant is measured with great accuracy.
- the temperature sensor is arranged in a protective tube.
- the protective tube results in reproducible measuring conditions. If the evaporator is close to the protective tube, the same distance always results between the evaporator and the temperature sensor.
- the protective tube prevents damage to the temperature sensor. This applies to possible damage to the temperature sensor during installation, but also when the refrigeration unit is fully loaded Press against the evaporator. In this case, the evaporator could damage it by pressure on the temperature sensor. Even such damage is prevented by the protective tube.
- the protective tube can be firmly anchored in the groove of the inner shell.
- a protective tube which is firmly connected to the evaporator.
- Such a protective tube could for example be provided with clip or locking means to be fixed in this way to the evaporator tube.
- a plastic would be suitable, which does not lose its elasticity even in great cold.
- the protective tube could also be made of metal and attached via a soldered or welded connection to the evaporator.
- the protective tube may be provided with an insertion funnel. Through the insertion funnel, the risk of damage to the temperature sensor is reduced during assembly.
- FIG. 2 shows a sensor receptacle mounted on the evaporator with a clamp
- FIG. 3 shows a sensor tube with insertion funnel attached to the evaporator tube.
- the refrigerator shown in Fig. 1 has an inner shell 1, which surrounds the interior for receiving refrigerated and / or frozen food. In order to allow no heat transfer from the environment into the interior, the inner shell 1 is enveloped by the insulating foam 2.
- the inner shell 1 is already equipped with receptacles for the wire tube evaporator 3.
- the shark ter 6 provided that press the wire tube evaporator 3 in its intended position.
- the wire tube evaporator 3 consists of a loop-shaped bent evaporator tube 4, which is stabilized via the transverse wires 5.
- the transverse wires 5 are welded at the top and the bottom to the evaporator tube 4.
- a groove 7 is provided in the cover part of the inner shell 1.
- the groove 7 is intended to receive a protective tube 8.
- the temperature sensor 9 is housed in the protective tube 8.
- the protective tube 8 is in direct contact with the transverse wires 5.
- the transverse wires 5 are thermally coupled via welding points with the evaporator tube 4, so that they have virtually the same temperature as the refrigerant.
- the distance of the temperature sensor 9 from the transverse wires 5 is determined by the strength of the protective tube 8. Direct contact of the temperature sensor 9 with stored cooling and / or freezing can not take place, since the wire tube evaporator 3 itself acts as a shield. Consequently, the same measuring conditions are always given for the control of the compressor, not shown here. A falsification of the measurement by stored refrigerated and / or frozen goods does not take place.
- the sensor receptacle 1 1 is attached by a clamp 12 directly to the evaporator tube 4.
- the clamp 12 has the spring legs 10, which have a certain bias, so that a positive connection between the clamp 12 and evaporator tube 4 takes place.
- the sensor receptacle 1 1 is pressed directly onto the evaporator tube 4.
- the clip 12 is made in one piece with the sensor receptacle 1 1 and made of plastic.
- a corresponding molded part can be extruded very inexpensively or produced as an injection-molded part.
- the temperature sensor inserted into the sensor receptacle 11 is shielded by the wire tube evaporator from the stored refrigerated and / or frozen food. A contact can not take place, so that there are always the same measuring conditions.
- the sensor tube 13 shown in FIG. 3 has an insertion funnel 14. This introductory hopper 14 facilitates the installation of the temperature sensor and prevents damage during installation.
- the sensor tube 13 may also be made of plastic. In this case, it is glued or potted with the evaporator tube 4.
- the sensor tube 14 can also be made of metal. In this case, a welding or soldering with the evaporator tube 4 is preferable.
