Definitions

  • the present invention relates to a refrigerator, in particular a household refrigeration appliance which is particularly suitable for cooling food, the quality of which critically depends on the climatic conditions of their storage, in particular wine.
  • the long-term storage of wines usually takes place in cellars whose temperature is generally different from the optimum drinking temperature of the wines.
  • the optimum drinking temperature is usually lower than the cellar temperature, while it may be higher for red wines.
  • To bring the wines to drinking temperature they are often placed in a refrigerator for cooling, where they are abruptly cooled down to its internal temperature, or they are brought to an inhabited room where they can be heated to its temperature.
  • Such abrupt temperature changes are exactly what you try to avoid in the long-term storage of wines in cellars, and they can negatively affect their quality.
  • a cooling device which is able to gently bring wine to a desired serving temperature in a controlled tempering process.
  • the tempering process starts at a temperature detected by a temperature sensor in the storage compartment, which is taken as the initial temperature setpoint. Starting from this initial value, the temperature set point gradually approaches the serving temperature during the temperature process.
  • the object is achieved with a refrigerator according to claim 1 of the present invention.
  • the end setpoint temperature and / or a rate of change of the setpoint temperature can also be set on the control part.
  • the tempering process in particular in an initial phase of the same, it may well be appropriate to adjust the target temperature to a temperature measured in the storage compartment. In this way, a possible deviation between the initial temperature of the bottles and the set start temperature setpoint can be taken into account.
  • the storage compartment is expediently equipped with a fan.
  • the fan between the storage compartment and an evaporator chamber is arranged.
  • control element is also set up to estimate an end time or a remaining duration of the tempering process and display it on a user interface. This is particularly useful in the case of a correction of the setpoint temperature based on a measured temperature, since in such a case the user can not estimate the duration of the tempering process itself.
  • the storage compartment is also assigned a heater and the control part is arranged to control the heating according to the target temperature.
  • the control part can expediently have a tempering standby state in which it keeps the storage compartment constant at the start setpoint temperature and starts a tempering process when a door operation is detected. This allows the user to bring the storage compartment before the tempering process to the correct starting temperature and to hold indefinitely on this. If a door operation indicates that the storage compartment has been loaded, the tempering process starts automatically. This is particularly useful when only small quantities of bottles are invited whose heat capacity is low. When the storage compartment is fully loaded, the heat capacity of the loaded bottles is so large compared to the heat capacity of the air in the compartment that the temperature of the compartment before the start of the tempering process has hardly noticeable influence.
  • Fig. 1 is a perspective view of a refrigerator according to the invention with three doors 1, 2, 3, each closing a storage compartment behind it.
  • the doors 1, 2, 3 are each essentially formed by a framed in a frame 4 insulating glass, which releases the view of the underlying storage compartment 5.6 and 7 respectively.
  • each storage compartment is divided by a plurality of horizontal floors 8, 9 of different depths.
  • the space between two adjacent bottoms 8, 9 is sized to store bottles lying therein; the distance between two adjacent bottoms 9 of great depth is chosen so that 9 bottles can be placed standing in a front edge region of each floor.
  • Illuminants may be placed in the frame 4 or outside the doors to illuminate the standing bottles.
  • the wines offered for consumption can be presented in a conspicuous and inviting manner.
  • the control panel 10 is connected via a bus 11 to a microcontroller 12 to receive user commands by operating keys of the control panel 10 and output messages of the microcontroller 12 on a display screen of the control panel 10.
  • the microcontroller 12 communicates with temperature sensors 13, 14 in each of the storage compartments 5, 6, 7, with one or more compressors 16, optionally with non-illustrated solenoid valves for distributing compressed refrigerant on evaporator 15 of the storage compartments, and with a fan 17 and a heater 18 in each storage compartment.
  • the plurality of temperature sensors, compressors and / or solenoid valves allow for control of the temperature in each of the compartments 5, 6, 7 independently of the others.
  • the temperature in each of the compartments 5, 6, 7 independently of the others.
  • Fig. 3 shows the appearance of the control panel 10 in a steady state operation.
  • the storage compartments 5, 6, 7 associated display fields are assigned to the display screen 22 display panels 19, 20, 21, whose arrangement simulates the arrangement of the compartments 5, 6, 7 on the device and displayed on each of which measured by the sensor 13 of each compartment temperature is. All three compartments are kept constant at a target temperature of +12 degrees Celsius.
  • the display screen 22 of the control panel 10 flanking keys 23 to 28 are assigned functions for controlling the device, which are illustrated by each adjacent to them on the display screen 22 displayed symbols.
  • Symbols displayed are essentially only the symbol 29 next to the key 26, which stands for the transition to a programming mode.
  • the button 26 By pressing the button 26 in turn, the individual compartments 6, 7, 8 are selected for programming, the programming readiness by inverting the selected tray corresponding display field, in Fig. 4 of the display panel 19 of the tray 6 is displayed.
  • the actuation of the button 23 causes in in Fig. 4 shown state the transition to a tempering programming mode, shown in Fig. 5 ,
  • a symbol 30 at the top left in an inverted central area of the display screen 22 identifies the selected storage compartment, here tray 6.
  • a graphic 31 displayed in the central area illustrates the timing of the tempering process with start and end temperatures, here 12 degrees Celsius and 17 Degrees Celsius, and with these values rising linearly with time.
  • the keys 23, 24 serve to decrement and increment the start temperature and the keys 26, 27 to increment and decrement the final temperature.
  • the rate of increase of the temperature during the tempering of, for example, 1 degree Celsius per hour is fixed here, it could also be the user for programming exempted.
  • the display image of the Fig. 5 can be left via the key 28 without starting a tempering process, as the adjacent crossed out thermometer symbol illustrates.
  • a tempering process is started simultaneously with leaving the display image.
  • the user arrives at the display image of Fig. 6 in which the parameters set for the tempering process can be seen in the display panel 19 of the compartment 6, in which the tempering process is to take place.
  • the device when the device is switched on, it initially goes into a stationary operating state for all compartments 5, 6, 7 in which the compartments remain constant at a setpoint temperature, as on the display image of the Fig. 4 adjustable, holds.
  • a user The device can switch on for some time before a planned tempering process to ensure that the trays have cooled down to said constant setpoint value at the beginning of the tempering process. This is particularly useful if only a small number of bottles to be tempered.
  • the setpoint temperature for this stationary cooling operation is equal to the starting temperature of a tempering process, ie equal to the temperature of a cellar, from which the bottles to be tempered are fetched; as related to Fig. 5
  • the user has the ability to program both temperatures differently.
  • the user can also switch the device on only after being loaded with bottles. In this case, he will generally not wait until the compartments have reached the setpoint temperatures for the stationary cooling operation, but initiate the tempering process immediately.
  • the user selects the programming mode for the tempering process of the compartment, that is, it calls the display image of the Fig. 5 on. If the parameters of the tempering process are set correctly, it starts by pressing the button 25. Even if the device has been switched on just before the tempering process, it only takes a few minutes for the evaporators 15 to cool down and cool air to be at the current one Temperature setpoint corresponding temperature is blown into the compartment 6. To regulate the temperature of the air flow of the fan 16 exposed temperature sensor 13 is used.
  • the microcontroller 12 compares the temperature sensor 14 at a shielded from the air flow of the fan 16, for example, immediately upstream of the evaporator 15 or in the immediate vicinity of the bottles in the chamber 6 detected temperature with the current temperature setpoint. If a deviation from the temperature setpoint is detected, then it can be concluded that the temperature of the loaded bottles does not match the programmed start temperature of the tempering process. In this case, an unnecessary extension of the tempering process or a rapid temperature jump at the beginning of the To avoid the tempering process, the microcontroller 12 adjusts the setpoint temperature to the temperature detected by the temperature sensor 14.
  • the microcontroller 12 begins to approach the setpoint temperature at a fixed rate of change of 1 degree Celsius per hour to the programmed end temperature. This change can be continuous or, as in DE 103 58 732 A1 described, take place in several discrete steps. From the predetermined rate of change of the temperature, the current setpoint temperature and the end temperature of the tempering process, the microcontroller 12 calculates the remaining duration of the tempering process and displays either this or a time at which the tempering process is completed on the display screen 22.
  • Fig. 7 shows such a situation: a tempering process takes place here only in compartment 6; the compartments 5, 7 are held stationary at 12 degrees Celsius, as can be read in their display panels 20, 21. On the display panel 19 of the tray 6, the end time of the tempering, 12:51, the current temperature of the tray 6, 13 ° C, and the final temperature of the tempering, 17 ° C, readable.
  • the microcontroller 12 When the final temperature is reached, it will be kept as a constant setpoint temperature of the compartment until the user again enters the programming mode for the tempering process ( Fig. 5 ). If he exits this programming mode via the key 28, the microcontroller 12 again uses the in Fig. 4 programmed setpoint temperature of 12 ° C. If the programming mode is exited via the button 25, a new tempering process starts immediately.
  • the user turns on the device and activates the programming mode for the tempering according to the Fig. 5 , If it leaves via key 28, the unit will remain in stationary cooling mode, and compartment 6 will be in place for in Fig. 4 set temperature.
  • the microcontroller goes into a tempering standby mode in which it first assumes the programmed start temperature of the tempering as a constant set temperature. This gives the user the ability to cool the tray to the cellar temperature and keep it at that temperature before loading with bottles, as long as nothing else happens.
  • the tempering process is triggered as soon as possible the microcontroller 12 detects the closing of the door 2 of the compartment 6, that is, if it can be assumed that the compartment 6 has been loaded with bottles.
  • the tempering process takes place as described above.
  • the temperature control process is reset and restarted with each door opening and closing.
  • the user can set a coupling between the tempering process and the lighting of the compartments 5, 6, 7 on the control panel 10, by which the lighting is switched on automatically when the final temperature of the tempering process is reached, while it does not reach the end temperature is, remains locked.
  • the user is made aware of the completion of the tempering process by addressing the lighting. Bottles that are currently undergoing a tempering process and have not yet reached their ripe for consumption, remain in the dark, so that the attention of the guests is directed primarily to the available bottles in another, illuminated tray.
