Abstract: A drive mechanism for a down draft vent system comprising a vertically directed, retractable open framework, which can be moved between an extended position and a lowered position by means of a drive motor, comprising at least two switches for switching off the drive motor and at least one actuating element for actuating the switch. In this arrangement at least one switch is actuated by means of the at least one actuating element depending on a force (FW) acting externally on the open framework. In addition to an end switch-off of the drive motor, this invention provides a safety function as a result of a resistive load switch-off which is effective both in the event of a resistance from below during retraction and also in the event of a resistance from above during extension of the open framework.

Abstract: An external fan for an extractor device, wherein the external fan includes a fan housing; a ventilator housing that is arranged in the fan housing and that has an air discharge; and a sound absorbing member that is arranged in the fan housing and that is opposite the air discharge of the ventilator housing.

Abstract: In order to simplify and reduce the production costs of a push-button switch, especially a push switch or a rocker switch, the switch has a time function, which is manually operated and can be reset by an electric pulse. The electromechanical rocker or push-button switch can be combined to form a device block switch with other rocker or push-button switches as usually used in exhauster hoods. As a result, time-controlled intensive and follow-up steps can be carried out.

Abstract: A filter arrangement for a range hood, which is used for separating at least one of particles and liquid drops from an air flow penetrating the filter arrangement. The filter arrangement includes at least two shells that are disposed one inside the other. The inventive filter arrangement is characterized in that the shells are removably connected to one another such that producing, handling, and cleaning the filter arrangement is simplified.

Abstract: A filter system extracts particles and/or drops of liquid from air flowing through the filter system. The filter system has a filter layer disposed in a plane and a cyclone collector that is disposed in the edge region of the filter layer. The cyclone collector is provided with a device which, compared with the filter layer, creates a higher flow speed and stronger vortexing of the circulating air. The cyclone collector can be produced from horizontal cyclone elements, curved, horizontal elements or from expanded metal.

Abstract: A securing device for a filter element, which can be detachably mounted on an extractor hood, has a connecting implement for detachably connecting the filter element to the associated extractor hood. The connecting implement catches the filter element when detaching the filter element from the extractor hood and prevents it from falling down. The connecting implement has a fixing element with a rod-like section and with a thickening connected thereto. The connecting implement also has a closure element with a U-shaped slot. The rod-like section of the fixing element is formed so that it fits the U-shaped slot of the closure element.

Abstract: An extraction unit for ventilating a cooking surface is provided that includes a retractable device permitting an extraction component of the extraction unit to be extended and retracted, a control unit comprising at least one actuating component, which is used to trigger the retractable device by a manual user entry, and a fan unit. The fan unit can also be controlled by the control unit, by means of the manual user entry for the actuating component. In addition, the actuating component can be configured as a rotary component, allowing at least one additional function of the extraction device to be controlled by the user by the rotation of the actuating component. The actuating component can also adopt a lowered position when the extraction unit is inactive and a position, in which it protrudes from the control unit, when the extraction unit is active.

Abstract: The production costs of a multiple contact switch with a time function are simplified and reduced. The electromechanical switch is manually operated one way and it is reset by an electric pulse. The novel switch may be combined with other switches to form a device block switch such as is typically used in extractor hoods and the like. Time-controlled intensive steps and time-delay steps can be created with the novel system.
