- the shape memory alloy wire contracts to override the spring force applied by the biased spring.
- the adjusting device of the household appliance may comprise an electrical energy source, by means of which the wire of a shape memory alloy can be acted upon with electrical energy. If the wire made of a shape memory alloy is subjected to electrical energy, so that in particular an electric current flows through it, then it heats up.
- the electrical energy source is e.g. an electrical voltage source whose electrical voltage is e.g. at the ends of the wire is made of a shape memory alloy.
- the electrical energy source is e.g. from a control device of the household appliance on and off. When the electrical energy source is switched off, the wire can cool down from a shape memory alloy.
- the wire made of a shape memory alloy has two ends, with which the wire made of a shape memory alloy is fastened at a fixed component of the domestic appliance at a distance from the pivot axis.
- the wire of a shape memory alloy is in particular additionally spaced from the pivot axis attached to the flap by means of a fastening device.
- the fastening device has a groove directed away from the pivot axis, in which the wire is guided by a shape memory alloy.

In the second unstable state, the preloaded spring also attempts to pivot the flap toward the first position so that when the shape memory alloy wire is cold, the bi-stable mechanism assumes its first stable state and thus holds the flap in its first position while the wire is off a shape memory alloy is not heated.
- the bi-stable mechanism comprises the following constituents:
- a component having a surface which is aligned at least approximately at right angles to the pivot axis and in which a groove-shaped heart-shaped contour is arranged, wherein the component part of the flap or rigidly connected thereto and thus the component and the heart-shaped contour with the flap pivots and the heart-shaped contour the two stable states and the two unstable states are assigned,
- a pin engaging in the heart-shaped contour cooperating with the heart-shaped contour such that the pin holds the flap in its first position when the bi-stable mechanism is in its first stable condition and holds the flap in its second position when the pin bi-stable mechanism has its second stable state.

- This component is for example part of the flap, e.g. integrally formed on this or the heart-shaped contour is arranged in a direction perpendicular to the pivot axis surface of the flap.
- the device may also be rigidly connected to the flap.
- the heart-shaped contour thus pivots with the flap. With the heart-shaped contour of the pin cooperates by engaging in the heart-shaped contour and holds the device and thus the flap in the stable states.
- a further aspect of the invention accordingly relates to a method for operating the household appliance according to the invention, comprising the following method steps:
- Cooling the shape memory alloy wire so that the biased spring will close the flap toward the first position of the flap can pivot until the bi-stable mechanism reaches its second state and the flap assumes its second position.
- the wire of a shape memory alloy is heated in particular by switching on the electrical energy source.
- the shape memory alloy wire contracts and, against the spring force of the biased spring, pivots the flap toward the second position and beyond until the bi-stable mechanism reaches its first unstable state.
- the electrical energy source is turned off, whereby the wire cools from a shape memory alloy and is pivoted by means of the prestressed spring in the direction of its first position.
- the bi-stable mechanism in particular the heart-shaped contour is pivoted in accordance with and goes into its second stable state in which in particular the pin holds the component and thus the flap in the second position and thus further pivoting of the flap in its first position prevented.
- the wire made of a shape memory alloy is cooled or turned off the electrical energy source.
- the wire of a shape memory alloy is heated in particular by switching on the electrical energy source.
- the shape memory alloy wire contracts and pivots the flap past the second position against the spring force of the biased spring until the bi-stable mechanism reaches its second unstable state.
- the electrical energy source is turned off, whereby the wire cools from a shape memory alloy and the flap is pivoted by means of the prestressed spring in the direction of its first position.
- the bi-stable mechanism in particular, the heart-shaped contour is pivoted in accordance with and returns to its first stable state, in particular, the pin holds the device and thus the flap in the first position, as long as the wire is cooled from a shape memory alloy.
- the wire made of a shape memory alloy is cooled or turned off the electrical energy source.
- SMA Shape Memory Alloy, English for shape memory alloy.
- the flap with the Aktiuator is used in particular for an improvement of the air damper for controlling the air flow in so-called No Frost devices.
- the flap, in particular the air flap is preferably pivoted with a V-shaped SMA wire as an actuator between the two positions.
- the wire of a shape memory alloy is thereby preferably fastened in V-shape to the flap. For example, when energizing the wire of a shape memory alloy, this heats up, shortens and pulls the flap in particular against a spring force in the direction of the second position.
- the attachment of the shape memory alloy wire is accomplished, for example, by crimping the shape memory alloy wire with another wire, e.g. a stainless steel wire, which may possibly simultaneously represent the electrical connection of the optionally existing electrical energy source.
- the pivot axis of the flap may preferably be connected to a bi-stable mechanism. This is actuated when the flap is pivoted towards its second position, e.g. the pen, e.g. a metal pin, into the intended opening of a heart curve locks. Due to the use of the wire of a shape memory alloy, a relatively quiet, if not silent, actuator can be provided. As a result, the pivoting of the flap can be relatively quiet, if not silent. There may be a relatively low energy consumption for pivoting the flap.

- the heart-shaped contour 44 is designed such that it allows the closing of the flap 21 when the bi-stable mechanism 41 or the component 42 is in its first stable state. If the bi-stable mechanism 41 or the component 42 is in the second stable state, then likewise the spring 45 tries to pull the flap 21 into its first position. Due to the heart-shaped contour 44, however, prevents the pin 47, as shown in Fig.
- FIG. 5c a complete pivoting back of the device 42 and thus closing the flap 21 with cooled wire 24 from a shape memory alloy.
- the pin 42 holds the component 42 in its second stable state and thus the flap 21 in its second position, ie in its open position, even without heating or impinging the wire 24 from a shape memory alloy with electrical energy.
- Figures 5a-d illustrate the operation of the bi-stable mechanism 41. When the flap 21 closes the opening 8, it is in its first position, in which the wire 24 has cooled from a shape memory alloy and thus by means of the prestressed spring 45 in particular can be pulled to its maximum length.
- the bi-stable mechanism 41 In the bi-stable mechanism 41 is in its first stable state, whereby the pin 47 cooperates with the heart-shaped contour 44 of the component 42 in such a way that the flap 21 allows the opening 8 to be closed or the flap 21 allowed, 45 take their first position by means of the prestressed spring. If now the flap 21 are opened so that air can flow through the opening 8 from the freezer compartment 4 into the coolable interior 3, the wire 24 is heated from a shape memory alloy, in the case of the present embodiment, the control device 10 with the wire 24th power source connected to a shape memory alloy to turn on the wire 24 made of a shape memory alloy with electrical energy.
- the wire 24 is composed of a shape memory alloy and thereby pivots the flap 21 with respect to the pivot axis 21, whereby the flap 21 opens the opening 8.
- the component 42 also pivots, whereby the pin 47 changes its position relative to the heart-shaped contour 44 until the bi-stable mechanism reaches the first unstable state illustrated in FIG. 5b.
- the flap 21 is opened slightly wider than in its second position. The flap 21 is thus pivoted beyond its second position.
- the control device 10 turns off the power source again, causing the shape memory alloy wire 24 to cool and thereby re-engage by means of the biased spring 45 can be stretched to its original length. This allows the prestressed spring 45 to pivot the flap 21 again so that it tries to close the opening 8 again. Due to the heart-shaped contour 44, however, the pin 47 is guided into a position within the heart-shaped contour 44, in which the bi-stable mechanism 41 and the component 42 reaches its second stable state. This is shown in FIG. 5c.
- the pin 47 prevents the member 42 from pivoting back so far that the flap 21 closes the aperture 8, thereby holding the flap 21 in its second position without the need for the shape memory alloy wire 24 heat. If the flap 21 is closed again, then the control device 10 turns on again the voltage source, whereby the wire 24 of a shape memory alloy contracts and thereby the flap 21 as long as pivoting opens until the bi-stable mechanism shown in Fig. 5d reached second unstable state. Thereafter, the controller 10 turns off the power source again, thereby cooling the shape memory alloy wire 24 and thus being stretchable, thereby allowing the biased spring 45 to pivot the flap 21 so as to close the opening 8. Due to the heart-shaped contour 44, the pin 47 now allows pivoting of the component 42 such that the bi-stable mechanism 41 is able to assume its first stable state again, thereby also allowing the flap 21 to assume its first position around the opening 8 to close.
