(21) In
(22) In the embodiment, the interior container 4 bounds a receiving space 6 with its walls, which is formed for receiving food. Here, the receiving space 6 is in particular formed as a refrigerating compartment.
(23) On the front side, the interior container 4 comprises a loading opening, via which food can be taken into or be removed from the receiving space 6. In the embodiment, the receiving space 6 is closable by two separate doors 7 and 8. The two doors 7 and 8 are pivotably arranged at the housing 2. The two doors 7 and 8 are arranged in the same height position viewed in height direction (y-direction) of the household refrigeration apparatus 1. In width direction (x-direction) of the household refrigeration apparatus 1, they are arranged next to each other such that they collectively close the receiving space 6 on the front side in the closed state. In particular, these two doors 7 and 8 are arranged in a common plane in the closed state, which is spanned by the height direction and the width direction.
(24) In
(25) Advantageously, the household refrigeration apparatus 1 comprises at least one further receiving space 9 for food. This further receiving space 9 is separated from the first receiving space 6. The further receiving space 9 can for example be a freezing compartment or a keep-fresh compartment or a further refrigerating compartment. Viewed in height direction, this further receiving space 9 is formed below the first receiving space 6. The further receiving space 9 is in particular bounded by further walls of an interior container, which can also be the interior container 4. Preferably, it is provided that the further receiving space 9 is bounded by a further door 10, which is shown in the closed state in
(26) It can be provided that the household refrigeration apparatus 1 comprises multiple, separate further receiving spaces 9, and further such explained drawers are preferably formed in this context. They can adjoin to the further receiving space 9 towards the bottom viewed in height direction. They are in particular also formed within the housing 2.
(27) Further, the door 10, in particular this front plate, is arranged in the same plane as the doors 7 and 8 in the closed state of the doors 7, 8 and 10. In particular, the doors 7, 8 and 10 are front-side vision components of the household refrigeration apparatus 1. In particular, they are also, if they are closed, arranged without overlap with each other.
(28) Moreover, the household refrigeration apparatus 1 comprises an ice maker 11. The ice maker 11 occupies a partial area of the volume of the receiving space 6 and is thermally insulated from the remaining volume of the receiving space 6. The ice maker 11 is formed to produce ice from water, which is supplied to the household refrigeration apparatus 1 via an external water supply line. In this context, ice form elements such as ice cubes or crushed ice can be produced.
(29) Further, the ice maker 11 is a constituent of the dispenser unit 12 of the household refrigeration apparatus 1. In this advantageous implementation, the dispenser unit 12 comprises an output unit 13 in addition to the ice maker 11. This output unit 13 can preferably be formed at a door 7, 8. In the shown embodiment, the output unit 13 is arranged at the door 7. This is in particular advantageous because the ice maker 11 is arranged in the left upper corner area of the total volume of the receiving space 6 with front-side view of the household refrigeration apparatus 1. For outputting produced ice form elements, short paths are achieved by this local positioning. The output unit 13 is fixedly installed at the door 7. Moreover, the output unit 13 is separated from the ice maker 11 and also decoupled from it in this context. In the closed state of the door 7, ice form elements produced by the ice maker 11 can get into the output unit 13 and be output via a front side 14 of the door 7. Thereto, it is provided that a recess is formed on the front side 14, which faces away from the receiving space 6 in the closed state of the door 7. A vessel can be placed in this recess to be able to collect the output ice form elements.
(30) Further, the dispenser unit 12 can also be formed for outputting liquid such as water or other drinks in addition to the output of ice form elements.
(31) In
(32) The interior container 4 comprises multiple walls, which bound the receiving space 6. For example, the interior container 4 is formed with a first vertical side wall, which is a first wall 15 in the example, an opposing second vertical side wall 16, a rear wall 17, which is a third wall in the example, a bottom wall 18 and a ceiling wall, which is a second wall 19 in the example.
(33) The first vertical side wall for example represents a first wall 15 of the interior container 4. In an embodiment, the ceiling wall represents a second wall 19 of the interior container 4, which is arranged angled, in particular at an angle of 90°, to the first wall 15.
(34) The ice maker 11 comprises a housing 20 (
(35) Moreover, the receiving space 21 is bounded by a further wall area 24. This further wall area 24 is an integral constituent of the rear wall 17 of the interior container 4. The wall areas 22, 23 and 24 directly join to each other.
(36) Moreover, the housing 20 comprises a wall unit 25 (
(37) In
(38) In the shown embodiment, the wall unit 25 also comprises an L-shaped positioning bracket 29. It is connected to the wall plate 28 on the one hand and to the wall plate 27 on the other hand with its ends. In depth direction (z-direction), this positioning bracket 29 is arranged in a front area and thus in a front end of this wall unit 25. It bounds a front-side opening of this wall unit 25 with the front area of the wall plates 27 and 28. The wall plates 27 and 28 are formed with an integral, L-shaped outer wall element 30 and an L-shaped and integral inner wall element 31 separate therefrom. In a clearance between the outer wall element 30 and the inner wall element 31, a thermally insulating material 32 is introduced. Thereby, the receiving space 21 of the ice maker 11 is thermally insulated from the remaining volume of the receiving space 6. A front-side, also L-shaped end flange 33 covers this clearance between the outer wall element 30 and the inner wall element 31 on the front side.

(40) Components of a mechanically, non-destructively detachable connection 35 are formed in the assembly area 34. The connection 35 can be formed to the effect that it is only formed for directly plugging components together. However, this plug connection can additionally also be formed as a locking connection and a locking can then additionally be provided besides simply plugging together. Thus, a locking connection is in particular also understood by a plug connection.
(41) This connection 35 comprises mating plug elements 36 and 37. These mating plug elements 36 and 37 are in particular formed integrally with the inner wall element 31. The mating plug elements 36 and 37 are formed as plug rails in the embodiment. They are oriented parallel to each other and extend linearly in depth direction. Moreover, it is provided that the assembly area 34 is formed in the front area viewed in depth direction of the housing 21. In particular, this assembly area 34 and thus also the connection 35 to the mating plug elements 36 and 37 is formed in a front third of length of the wall unit 25. This means that these mating plug elements 36 and 37 are formed in a front third of length of this entire length of the wall unit 25 upon length view of the wall unit 25 in depth direction. In particular, the mating plug elements 36 and 37 are thus formed in a front third of length of the housing 21 and thus also of the entire ice maker 11.
(42) In an implementation, it is provided that the mating plug elements 36 and 37 are formed in a corner area 38 with front-side view of the wall unit 25 and thus with view in depth direction. In particular, this corner area 38 is a left-side, lower corner area with this front-side view.

Here, it is in particular linearly displaceable. Here, the actuating element 45 is arranged obliquely inclined and thus can be moved on an obliquely inclined linear guiding track relative to a retaining unit 46 of the drive unit 39. Here, the actuating element 45 is formed as a duct-like box. The direction of movement of the actuating element 45 relative to the retaining unit 46 is shown by the arrow P1.
(47) Further, the actuating element 45 comprises at least one engagement element 47, which is guided in a guiding groove 48 of the retaining unit 46.

In an advantageous implementation, it is provided that the element 43 is present in addition to these plug elements 42, 44 and the mating plug elements 36 and 37. It is preferably formed with a locking element 43a. This locking element 43a plunges into the receptacle 49 in the assembled state, as it is shown in
(52) In that the element 43 is actuated at its front-side edge, in particular upward bent, this snapped or locked state can be detached and then the module 40 can be forward pulled by a movement linear viewed in depth direction.
(53) In the assembly, thus, this module 40 is provided and the wall unit 25 is also provided. For assembling this drive unit 39 to the wall unit 25, this module 40 is displaced into the wall unit 25 coming from the front. Thereto, the plug elements 42 and 44 are coupled to the mating plug elements 36 and 37. Upon then guided linear displacement of the module 40 in depth direction to the rear, the plug elements 42 and 44 are moved until they have reached the stops 36a and 37a. Snapping of the locking element 43a in the receptacle 49 is then also automatically achieved on this movement path.
(54) In

(56) In this representation, the snapped state between the locking element 43a of the element 43 and the receptacle 49 is shown.
(57) Moreover, it is also apparent that the drive unit 39 comprises a motor 51, which is arranged in the module housing 41. In the embodiment, it is provided that the drive unit 39 moreover comprises a cam 52. The cam 52 is coupled to the motor 51. On the other hand, the cam 52 is coupled to the actuating element 45. The cam 52 is set in a rotational movement by the motor 51. By this rotational movement, the actuating element 45 is actuated. Therein, the coupling between the cam 52 and the actuating element 45 is such that the rotational movement of the cam 52 is converted to a linear movement according to the arrow P1.
