The phrase that a first cold compartment is "adjacent" to a second cold compartment with respect to the height direction is to be understood in particular as meaning that an intermediate area, which is arranged in the height direction between the first cold compartment and the second cold compartment, is free of additional cold compartments and / or that in particular the first cold compartment and the second cold compartment adjoin one another in the vertical direction. In this way, in particular, a compact design can be achieved.

For example, the household refrigeration appliance and in particular the household refrigeration appliance could only have the cold compartment and the second cold compartment and in particular be free of additional cold compartments. The domestic refrigeration appliance device preferably has at least one third refrigeration compartment, which is separately accessible and which is arranged with respect to a height direction, in particular directly, adjacent to the refrigeration compartment.

The third cold compartment is preferably designed as a refrigerated compartment. In the vertical direction, the cold compartment is arranged in particular between the second cold compartment and the third cold compartment. In this way, in particular, a large number of cold compartments can be made available, as a result of which, in particular, a high degree of flexibility can be achieved and / or a high level of operating convenience can be provided to an operator.

The second cold compartment could, for example, be arranged above the cold compartment and the third cold compartment with respect to the height direction. In particular, the third cold compartment could be arranged below the cold compartment and the second cold compartment with respect to the height direction. The second cold compartment is preferably arranged below the cold compartment and the third cold compartment with respect to the height direction. The third refrigeration compartment is arranged above the refrigeration compartment and the second refrigeration compartment in particular with regard to the height direction. In particular, the second cold compartment is designed as a lowermost cold compartment with respect to the height direction. The third cold compartment is designed in particular as an uppermost cold compartment with respect to the height direction. This enables particularly easy access to the second refrigeration compartment, in particular also for smaller people, whereby a high level of operating convenience can be provided in particular.

In particular, the evaporator unit has an assembly of evaporators of the refrigeration circuit. An “evaporator unit” is to be understood in particular as a unit which, in an operating state, at least partially converts at least one refrigerant from a liquid physical state to a gaseous physical state. The phrase that the evaporator "at least partially" converts at least one refrigerant from a liquid state of aggregation to a gaseous state of aggregation in an operating state is to be understood in particular as meaning that the evaporator in the operating state has a share of at least 10%, in particular at least 20% , advantageously at least 40%, particularly advantageously at least 60%, preferably at least 80% and particularly preferably at least 90% of a refrigerant passing through the evaporator in the operating state is converted from a liquid state to a gaseous state. An “evaporator” is to be understood in particular as a unit through which at least one refrigerant component of a refrigerant of the refrigeration circuit flows in an operating state and which at least partially converts the refrigerant component from a liquid state to a gaseous state in the operating state. The expression that an evaporator “serves” a refrigeration compartment is to be understood in particular to mean that the evaporator is provided for cooling the refrigeration compartment and, in particular, extracts heat from the refrigeration compartment in an operating state. The household refrigerator device has in particular at least one control unit which is provided in particular to control and / or regulate at least the evaporator.

The control unit has in particular at least one computing unit and in particular in addition to the computing unit at least one memory unit in which in particular at least one control and / or regulating program is stored, which in particular is intended for execution by the Computing unit is provided. In this way, in particular, a compact and / or low-component design can be achieved, since in particular a single evaporator can be used to cool at least two cold compartments. For example, further evaporators, such as in particular a second evaporator and / or a third evaporator, could be dispensed with, as a result of which, in particular, low costs could be achieved.

It is further proposed that the evaporator is arranged in a border area of the refrigeration compartment and the second refrigeration compartment with respect to the height direction.

As a result, particularly efficient cooling of the refrigeration compartment and the second refrigeration compartment can be achieved, whereby an environmentally friendly design can be achieved in particular. In particular, cooling of cold compartments that are far away can be dispensed with, which in particular enables a low energy loss.

It is also proposed that the household refrigerator device, in particular in addition to the evaporator, have at least one third evaporator which serves the third refrigeration compartment. In particular, the refrigeration device and in particular the household refrigeration device device could be free of a second evaporator. The third evaporator is in particular part of the refrigeration cycle. In particular, the evaporator and the third evaporator are arranged together in the refrigeration circuit. For example, the evaporator and the third evaporator could be connected in parallel to one another and / or in series. In this way, particularly efficient and / or targeted cooling of the third refrigeration compartment can be achieved, whereby in particular an environmentally friendly and / or energy-saving design can be achieved.

It is further proposed that the evaporator, in addition to the refrigeration compartment and the second refrigeration compartment, also serve the third refrigeration compartment. In particular, the household refrigerator and in particular the household refrigerator device could be free of a second evaporator and a third evaporator. In this way, in particular, a small variety of components and / or low storage can be achieved, whereby low costs can be achieved in particular.

A particularly high level of operating convenience can in particular be achieved by a household refrigerator with at least one household refrigerator device according to the invention.

The household refrigerator device should not be limited to the application and embodiment described above.

In the case of a shock cooling process, maximum cooling capacities, for example for shock cooling and / or for shock freezing, could be achieved, for example, with the highest possible evaporator temperatures. In a storage process, for example, the highest possible evaporator temperatures could achieve minimal energy consumption, for example both for a customer and for an energy efficiency classification.

For example, the control unit could 70c by means of the evaporator 22c downstream temperature sensor (not shown explicitly, but in the symbol for the flow rate setting element 58c included) check whether the refrigerant is after the evaporator 22c has completely evaporated. With a flow adjustment element 58c , which is designed as a thermostatic expansion valve, this signal could be converted directly into an adjustment of a position of the expansion valve, which could, for example, ensure that after the evaporator 22c the refrigerant is always overheated. For example, alternatively, the control unit could 70c the signal from the temperature sensor via a comparison with a temperature value at the inlet of the evaporator 22c to control a flow adjustment element 58c which is designed as an expansion valve controlled by an electric motor, use to control the expansion valve in such a way that it is again ensured that after the evaporator 22c the refrigerant is always overheated.

12 shows an alternative refrigeration cycle 48d which differs from the in 11 shown refrigeration cycle 48c differs for example in that a flow adjustment element 58d , advantageous instead of one in 11 expansion valve shown, has at least one throttle. For example, a throttle could be sufficient, such as in the case of a low necessary efficiency.

In the present exemplary embodiment, the flow adjustment element 58d advantageously two throttles, which are advantageously dimensioned differently. This could, for example, create an extremely efficient refrigeration cycle 48d can be achieved. A cold compartment designed as a shock compartment 14d could for example be provided for a storage process. The chokes are beneficial to the evaporator 22d upstream and advantageous for supplying the evaporator 22d provided with refrigerant.

A first of the throttles could for example be provided for a larger flow. A second of the throttles could be provided for a smaller flow rate, for example. For example, a control unit could 70d provide a higher cooling capacity in a shock cooling process by means of the first throttle. For example, the control unit could 70d provide a lower cooling capacity in a storage process by means of the second throttle.

A flow adjustment unit 56d advantageously has a switching unit 132d which, for example, could have at least one solenoid valve and which refrigerant could advantageously optionally lead to a first of the throttles or to a second of the throttles or, for example, to both of the throttles or, for example, to neither of the throttles.

By cleverly switching back and forth using the switching unit 132d between the two throttles the control unit can 70d advantageously also set a value between the highest cooling capacity and the lowest cooling capacity.

In this way, for example, an optimal flow value can be set for respective operating states, at which, for example, both a necessary cooling capacity and maximum efficiency could be ensured. For example, the refrigeration cycle could 48d be optimized in terms of efficiency if, as for example in the case of 11 shown refrigeration cycle 48c , a control unit 70d overheating after the evaporator 22d monitored and by setting a defined superheating after the evaporator 22d a flow optimized.
