A domestic dishwasher comprises a washing container and a door pivotably mounted on the washing container for closing the same. The door may be spring-biased by means of a spring in the direction of its closed state so that when it is unlocked it will not open uncontrollably and injure a user. For monitoring a fault of this spring, for example, micro-switches can be used. For example, such a monitoring system can prevent a drying assistant from automatically opening the door in the event of a fault and dropping the door with full force.

The EP 2 636 355 B1 describes a dishwasher with a pivotable about a horizontal axis door for closing a treatment room, which is provided with a door spring, which serves to slow down the movement of the door when swinging down, and with a sensor with which the functioning of the door spring can be monitored , and an additional deceleration means, which is activated in the event of a detected by the sensor failure of the door spring and is adapted to decelerate the movement of the door when swinging down.

The DE 11 2007 000 423 B4 shows a dishwasher having a housing for receiving dishes to be rinsed therein, an opening in a front and a propeller shaft, a door which is rotatably mounted with the propeller shaft for selectively opening / closing the opening in the housing, and a waste prevention unit for preventing the door from falling off the hinge shaft in a case where the door rotates, the waste prevention unit including a hinge bracket provided on the door, the hinge bracket having a hinge slot formed therein; to arrange the hinge shaft therein, wherein the hinge slot has an insertion hole for inserting the hinge shaft therethrough, a seat portion for setting the hinge shaft when the door is closed, and a holding step disposed at a predetermined distance from the seat portion, wherein the holding step suitable for holding the propeller shaft when si ch the PTO shaft a predetermined distance moves to open the door, and wherein an inner periphery of the hinge slot which connects the insertion opening with the seat portion is bent at least once.

Against this background, an object of the present invention is to propose an improved household dishwasher.

Accordingly, a household dishwasher having a washing container, a door for closing the washing container, a hinge with the aid of which the door is hinged to the washing container to pass the door from an open state to a closed state and vice versa, a biasing means , which spring-biased the door in the direction of the closed state, and proposed a purely mechanical locking device. The locking device is adapted to lock the door in case of damage to the biasing means to prevent an automatic movement of the door in the open state.

Characterized in that the locking device is provided, it can be reliably prevented that the door opens uncontrollably when unlocking the same. A violation of a user is thereby avoided. Cost-intensive and error-prone electronic components can be dispensed with. As a result, the household dishwasher can be produced inexpensively.

The biasing device is used in particular to decelerate a movement of the door when opening the same. The biasing device can therefore also be referred to as a braking device. Damage to the pretensioner means that it breaks or breaks. For example, the biasing device may comprise a cable and / or a spring element. Upon breakage or rupture of the rope and / or spring element, the locking device locks the door. In the opened state, the door closes the rinsing container, and in the closed state, a charging opening of the rinsing container is open, so that in the opened state a Spülgutaufnahme the domestic dishwasher from the washing out and can be moved into this. In the washing container are preferably several, For example, three, Spülgutaufnahmen arranged one above the other. In the Spülgutaufnahmen Spülgut can be recorded.

When the door is moved from the closed state to the open state, the biasing means is biased. In the closed state, the biasing device is preferably at least approximately relaxed. The biasing device is in particular adapted to act against a dead weight of the door. However, the biasing device is preferably not designed so strong that it can close the door independently. The biasing device only supports closing the door or brakes it when opening the same. In this case, an automatic movement of the door into the open state means, for example, that the door opens due to its own weight without an external introduction of force. Especially when the door is unlocked.

By the fact that the locking device works or works purely mechanically, it is to be understood that the locking device does not comprise any electronic components, such as sensors, switches, actuators or the like. That is, the locking device is sensorless or sensor-free. More precisely, the locking device comprises only mechanical components which interact with one another, for example for power transmission. The locking device may be a brake. In particular, the locking device is adapted to mechanically block or at least slow down the door.

Preferably, the household dishwasher comprises two such hinges, which are provided on opposite side walls of the washing compartment. The hinges may be provided on a base support and / or on a frame of the washing container. With the help of the hinges, the door is pivotable about an axis of rotation to spend them from the open state to the closed state and vice versa. However, only one hinge will be discussed below.

According to one embodiment, the locking device comprises an engagement element, which is coupled to the hinge, and a counter-engagement element, wherein the engagement element for locking the door engages positively in the counter-engagement element. In particular, the engagement element is rotatably coupled to the hinge.

The Fig. 5 shows a schematic view of another embodiment of the engagement member 23. In this embodiment of the engagement member 23 includes this made of a metal material core 36 which is fixedly connected by means of a crimped connection 37 with the cable 21. The core 36 is, for example, encapsulated with a plastic material by means of a plastic injection molding process to form the engagement element 23. The bolt portion 24 may be part of the core 36.

The Fig. 6 shows a schematic view of another embodiment of the engagement member 23. In this embodiment of the engagement member 23, the engagement member 23 includes a metallic core 38 on which the first engagement hooks 25 are formed. However, the core 38 is asymmetrical, so that the engagement element 23 pivots on damage of the biasing device 19 due to its own weight in the direction R1 to the first counter-engagement element 27. The bolt portion 24 may be part of the core 38. The second engagement hooks 26 of the engagement element 23 are dispensable in this embodiment of the engagement element 23. However, the engagement element 23 is additionally combined with the spring element 31.

The Fig. 7 shows a greatly enlarged detail view of a development of the household dishwasher 1 with a view of the hinge 16. This embodiment of the Household dishwasher 1 differs from the embodiment of the household dishwasher 1 according to the Fig. 3 only in that only one counter-engagement element 27, namely the first counter-engagement element 27, is provided. On the second counter-engagement element 29 is omitted.

The Fig. 8 shows a greatly enlarged detail view of another embodiment of the household dishwasher 1 with a view of the hinge 16. In this embodiment of the household dishwasher 1, in contrast to the embodiment of the household dishwasher 1 according to the Fig. 7 the first counter-engagement element 27 is not provided and provided for the second counter-engagement element 29. The engagement element 23 is spring-biased towards the second counter-engagement element 29 by means of a spring element 39 which is fastened to the engagement lever 23 by means of a first attachment point 40 on the hinge lever 17 and by means of a second attachment point 41. That is, in case of damage of the biasing means 19, the engagement member 23 pivots in the direction R2 in the clockwise direction in the direction of the second counter-engagement member 29, so that the second engagement hooks 26 of the engagement member 23 in positive engagement with the Gegeneingriffshaken 30 of the second counter-engagement member 29 advised.

The Fig. 9 shows a greatly enlarged detailed view of a further development of the household dishwasher 1 with a view of the hinge 16. In this embodiment of the household dishwasher 1, a counter-engagement element 42 is provided in the form of a rotatable about a rotation axis 43 disc. The rotation axis 43 can be arranged coaxially with the axis of rotation 5. Alternatively, the axes of rotation 5, 43, as in the Fig. 9 shown, also be spaced from each other. However, the rotatability of the counter-engagement element 42 about the rotation axis 43 is limited or damped. That is, the counter-engagement element 42 is difficult to rotate about the rotation axis 43. This can be achieved for example by the provision of a damper, in particular a rotary damper, or by a corresponding stiff fit of the rotation axis 43 and thus by friction.

The counter-engagement element 42 comprises a plurality of counter-engagement hooks 44, of which in the Fig. 9 however, only one is provided with a reference numeral. The counter-engagement hooks 44 are preferably arcuately curved. However, the mating hooks can 44 also be straight. The first engagement hooks 25 of the engagement element 23 are adapted to engage positively in the mating engagement hooks 44 of the counter-engagement element 43. In case of damage to the biasing means 19, the engagement element 23 pivots due to its spring bias by means of the spring element 31 in the direction R1 counterclockwise to the counter-engagement element 42 in order to get into this with positive engagement.

Characterized in that the counter-engagement member 42 is rotatable about the rotation axis 43, even if the biasing means 19 is damaged, the door 3 can be opened. In this way, even if the pretensioning device 19 is damaged, for example, still items from the household dishwasher 1 can be dispensed with.

Due to the provision of the locking device 22 can be dispensed with costly and sensitive electronic components. It is a simple installation of the household dishwasher 1 possible. The security is significantly increased because the door 3 is reliably intercepted in all its positions. A violation of a user is thereby reliably prevented.
