This object is achieved by the subject matter having the features of the independent claim. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims.

According to one aspect of the invention, the object is achieved by a household appliance having a closure element for covering a maintenance opening, in which the closure element has at least one laterally displaceable locking slide for locking the closure element in the maintenance opening and a rotary closure for the manual

Actuation of the locking slide includes. As a result, for example, the technical advantage is achieved that the closure element can be locked and unlocked by means of a single rotational movement. A household appliance is a device that is used for household management. This may be a large household appliance, such as a washing machine, a tumble dryer, a dishwasher, a cooking appliance, an extractor hood or a refrigerator, such as a refrigerator. a refrigerator, a freezer or a fridge-freezer. But this can also be a small household appliance, such as a

Water heater, a coffee machine, a food processor or a vacuum cleaner.

In an advantageous embodiment of the household appliance, the rotary closure is rotatably mounted in the middle of the closure element. As a result, for example, the technical advantage is achieved that the screw cap is easily accessible. In a further advantageous embodiment of the household appliance, a rotation angle between an unlocking position of the rotary closure and a locking position of the rotary closure is less than 90 °. As a result, for example, the technical advantage is achieved that the closure element can be quickly locked and unlocked with a single handle.

In a further advantageous embodiment of the household appliance has the

Closure element on a rectangular shape. As a result, for example, the technical advantage is achieved that the closure element can be inserted into a rectangular maintenance opening.

In a further advantageous embodiment of the household appliance includes the

3 is an exploded view of the closure element;

4A and 4B, a rear view of the closure element with

Locking pushers, and

Fig. 5A and 5B is a perspective view of the closure element.

Fig. 1 shows a schematic view of a household appliance 100. The household appliance 100 is for example a tumble dryer. The tumble dryer comprises a maintenance opening 103, which is covered or closed by means of a closure element 101 as a service cover. Behind the closure element 101 is, for example, a lint filter or other component of the household appliance 100, which is to be made accessible from the outside from time to time.

Fig. 2A shows a view of the closure element 101 with a rotary closure 107 in a closed position. The closure member 101 has a rectangular shape that closes the rectangular service opening 103. The rotary closure 107 is located in the middle of the closure element 101. Furthermore, the closure element 101 comprises four laterally slide out locking slide 105-1, 105-2, 105-3 and 105-4, each protruding on one side 1 13-1, 1 13-2, 1 13-3 and 1 13-4 of the closure element 101.

The locking slide 105-1, 105-2, 105-3 and 105-4 penetrate when locking in the direction of arrow in corresponding receptacles in the maintenance opening 103, so that the closure element 101 on each side 1 13-1, 1 13-2, 1 13-3 and 1 13-4 is locked. By turning the rotary closure 107, the locking slides 105-1, 105-2, 105-3 and 105-4 are laterally retracted or extended. In addition, the closure element 101 comprises reinforcing ribs 11, which are arranged concentrically around the rotary closure 107, so that the stability of the closure element 101 is increased.

Fig. 2B shows a view of the closure element 101 with the rotary closure 107 in an open position. In the open position, the locking slides 105-1, 105-2, 105-3 and 105-4 are retracted, so that the closure element 101 can be removed from the maintenance opening 103. The locking slides 105-1, 105-2, 105-3 and 105-4 are withdrawn by turning the screw cap 107.

3 shows an exploded view of the closure element 101. The closure element 101 comprises an inner cover 123, the locking slides 105-1, 105-2, 105-3 and 105-4 and the rotary closure 107 and a cover cap (not shown). The inner lid 123, the lock slides 105-1, 105-2, 105-3 and 105-4, the screw cap 107 and the cap are formed of, for example, injection-molded parts.

The inner lid 123 is concentric around the rotary closure 107

Reinforcing ribs 1 17 reinforced. The reinforcing ribs 1 17 at the same time form a guide for the locking slide 105-1, 105-2, 105-3 and 105-4. For this purpose, the reinforcing ribs 1 17 recesses in which the locking slide 105-1, 105-2, 105-3 and 105-4 are inserted.

The locking slide 105-1, 105-2, 105-3 and 105-4 are connected by an elastic spring ring 1 15 with each other, so that the system is given a bias and the insertion of the closure member 101, a reliable locking and locking is ensured.

The rotary closure 107 is connected to a screw 125 at an axis of rotation 127 of

Inner lid 123 attached. The rotary closure 107 is circular and has in the center of a bowl-like depression 121. Across the recess 121, the handle member 1 19 extends, so that the rotary closure 107 has no protruding parts.

Fig. 4A shows a rear view of the closure element 101 with the

Locking slides 105-1, 105-2, 105-3 and 105-4 in the closed position. On the back of the rotary closure 107 is a spiral groove 109 for insertion of an actuating portion 1 1 1 of the locking slide 105. By the operating portion 1 1 1 in the spiral groove 109 of the rotary closure 107, the locking slide 105-1, 105-2, 105- 3 and 105-4 when turning the

Turn-lock 107 moves translationally.

By a pivoting movement of the rotary closure 107 by 90 ° degrees, a linear locking of the closure element 101 takes place simultaneously at four points. The locking slide 105-1, 105-2, 105-3 and 105-4 are guided over the cam track defined by the groove 109 such that a uniform translational movement in the opening or closing direction is formed. The locking slides 105-1, 105-2, 105-3 and 105-4 describe the same way, so that after reaching the open position, the closure element 101 can be removed with a handle. 4B shows a further rear view of the closure element 101 with the

Locking slides 105-1, 105-2, 105-3 and 105-4 in the open position. In the open position, the locking slides 105-1, 105-2, 105-3 and 105-4 are pulled inward and the elastic spring ring 1 15 compresses like a wave. The

Locking slides 105-1, 105-2, 105-3 and 105-4 are by cross-shaped

Reinforcing ribs stabilized.

FIGS. 5A and 5B show further perspective views of the closure element 101. By turning the rotary shutter 107, the lock slides 105-1, 105-2, 105-3 and 105-4 move, so that the shutter member can be locked. On the rear side of the closure element 101, a left and right side wall 129 are respectively formed, through which the closure element 101 can be guided during insertion into the maintenance opening 103.

The locking slides 105-1, 105-2, 105-3 and 105-4 have a flat, rectangular in cross-section shape, so that this space-saving integrated into the closure element 101 can be. The closure element 101 may be covered with a cover, not shown, which comprises an opening for the rotary closure 107. As a result, the mechanism inside the closure element 101 can be protected from damage.

All of the features explained and shown in connection with individual embodiments of the invention may be provided in different combinations in the article according to the invention in order to simultaneously realize their advantageous effects.

The scope of the present invention is given by the claims and is not limited by the features illustrated in the specification or shown in the figures.
