Problems solved by technology

[0004] The main problem with the energy efficiency of this method is that a single evaporator outside the variable compartment must also cool the other compartment, because when one of the other compartments has a cooling demand, the variable compartment's Heating must be interrupted and the evaporator compartment must be cooled at least down to the rated temperature of the other compartment and then heated again

Embodiment Construction

[0020] figure 1 A schematic sectional view cut through the lower part of the domestic refrigeration appliance is shown. The body 1 and the doors 2 , 3 , 4 delimit a plurality of storage compartments, here the freezer compartment 5 and the flexible compartment 6 and the evaporator compartment 7 . The evaporator chamber 7 is here arranged vertically between the compartments 5 , 6 and the rear wall 8 of the body 1 ; an arrangement on a horizontal partition wall between two storage compartments is also conceivable.

[0021] The horizontal partition wall 9 between the flexible compartment 6 and the only partially shown normal refrigerated compartment 10 can extend continuously from the doors 3 , 4 up to the rear wall 8 , wherein a separate compartment for the normal refrigerated compartment 10 is then provided. There are evaporators. Alternatively, however, the evaporator chamber 7 and the evaporator 11 arranged therein can also be provided for cooling all three compartments 5, 6...

Abstract

The invention relates to a refrigerating appliance, in particular a domestic refrigerating appliance, comprising a flexible compartment (6) capable of operating at different temperatures, an evaporator compartment (7) arranged separately from the compartment (6) ) in the evaporator (11). The evaporator (11) is assigned defrost heating means (16) and ventilation means (18) for driving an air flow between the evaporator chamber (7) and the compartment (6). A control unit (19) is provided for increasing (S1) the setpoint temperature (T soll ) to simultaneously operate the ventilation device (18) and the defrost heating device (16) in order to heat the flexible compartment (6).

Description

technical field [0001] The present invention relates to a refrigerating appliance, in particular a domestic refrigerating appliance, having compartments which can be optionally used as refrigerating compartments or as freezing compartments at widely different rated temperatures, typically according to the needs of the user The cells are also called flexible cells or variable cells. Background technique [0002] When the user wants to switch the variable compartment from freezing operation to normal refrigerating operation, a long time elapses until the new target temperature is reached only by heat flow from the surrounding environment. As long as the new rated temperature has not been reached, the use of variable compartments is risky as the contents may be damaged at too low a temperature. [0003] It is therefore proposed in WO 2009 / 061076 A2 to use a defrost heater in order to heat the variable compartment more quickly after increasing the setpoint temperature. [0004...
