The implementation of the invention

In FIG. 1 shows a schematic view of a household appliance 100. The household appliance 100 is, for example, a tumble dryer. The tumble dryer includes a maintenance opening 103, which is covered or locked by the closure member 101 as a cover for servicing operations. Behind the closure element 101 is, for example, a sieve for the pile or other component of the household appliance 100, which from time to time should be accessible from the outside.

In FIG. 2A shows a view of a closure member 101 with a rotary shutter 107 in a closed position. The closing element 101 has a rectangular shape that closes the rectangular opening for maintenance 103. The rotary shutter 107 is located in the center of the closing element 101. In addition, the closing element 101 includes laterally extending blocking valves 105-1, 105-2, 105- 3 and 105-4, each of which protrudes from one of the sides 113-1, 113-2, 113-3 and 113-4 of the closing element 101.

When locking, the gate valves 105-1, 105-2, 105-3 and 105-4 penetrate in the direction of the arrows into the corresponding sockets in the maintenance hole 103 so that the closing element 101 on each side 113-1, 113-2, 113-3 and 113-4 are fixed. Blocking latches 105-1, 105-2, 105-3 and 105-4 are inserted or output on the sides by rotation of the rotary shutter 107. Additionally, the closing element 101 includes reinforcing ribs 117 that are concentrically around the rotary shutter 107, so that the stability the closing element 101 rises.

In FIG. 2B is a view of the closure member 101 with the butterfly valve 107 in the open position. In the open position, the blocking valves 105-1, 105-2, 105-3 and 105-4 are retracted, so that it is possible to remove the closing element 101 from the opening for maintenance 103. The blocking valves 105-1, 105-2, 105-3 and 105-4 are retracted inward by rotation of the rotary shutter 107.

In FIG. 3 shows an exploded view of the closure member 101. The closure 101 includes an inner cover 123, blocking latches 105-1, 105-2, 105-3 and 105-4 and a rotary shutter 107, as well as a cap not shown. The inner cover 123, blocking valves 105-1, 105-2, 105-3 and 105-4, the butterfly valve 107 and the cap are formed, for example, by molded products.

The inner cover 123 is reinforced by reinforcing ribs 117 extending concentrically around the rotary shutter 107. The reinforcing ribs 117 simultaneously form a guide for blocking valves 105-1, 105-2, 105-3 and 105-4. For this purpose, reinforcing ribs 117 have recesses in which the locking latches 105-1, 105-2, 105-3 and 105-4 are inserted.

Blocking latches 105-1, 105-2, 105-3 and 105-4 are connected to each other by an elastic spring ring 115, so that the system is pre-stressed and when the closure element 101 is inserted, it is securely locked and locked.

The butterfly valve 107 is mounted on the axis of rotation of the inner cover 123 with a screw 125. The butterfly valve 107 is circle-shaped and has a cup-shaped recess 121 in the center. The handle element 119 extends across the recess 121 so that the butterfly valve 107 does not have protruding parts .

In FIG. 4A shows a rear view of the closure member 101 with blocking latches 105-1, 105-2, 105-3 and 105-4 in the closed position. On the rear side of the rotary shutter 107, there is a spiral groove 109 for inserting the active portion 111 of the blocking valve 105 into it. When the rotary shutter 107 is rotated, the blocking valves 105-1, 105-2, 105-3 and 105-4 linearly move in the spiral groove 109 of the rotary valve shutter 107 by means of the acting section 111.

As a result of the rotary movement of the rotary shutter 107 through 90 °, the blocking element 101 is linearly locked at four points simultaneously. In this case, the locking valves 105-1, 105-2, 105-3 and 105-4 are carried out along a curved path defined by the groove 109, so that there is a uniform linear movement in the direction of opening or closing. Blocking valves 105-1, 105-2, 105-3 and 105-4 describe the same path, so that after reaching the open position, it is possible to remove the closing element 101 using the handle.

In FIG. 4B shows another rear view of the closure member 101 with blocking latches 105-1, 105-2, 105-3 and 105-4 in the open position. In the open position, the blocking valves 105-1, 105-2, 105-3 and 105-4 are pulled inward, and the elastic spring ring 115 is compressed in a wave-like shape. Blocking valves 105-1, 105-2, 105-3 and 105-4 are stabilized by cross-shaped reinforcing ribs.

In FIG. 5A and 5B show the following axonometric images of the closure member 101. As the rotary shutter 107 rotates, the blocking shutters 105-1, 105-2, 105-3 and 105-4 move, so that the closure can be locked. On the rear side of the cover member 101, respectively, left and right side walls 129 are formed by which the cover member 101, when inserted, is inserted into the maintenance hole 103.

The blocking valves 105-1, 105-2, 105-3 and 105-4 have a flat shape, rectangular in cross section, so that they can be compactly integrated into the closure element 101. It is possible to cover the closure element 101 with a cap not shown, which has an opening for rotary shutter 107. This allows you to protect from damage the mechanical elements in the inner part of the closing element 101.

All the features explained and shown in combination with individual embodiments of the invention can be provided in the subject according to the invention in various combinations in order to simultaneously realize their preferred effects.
