Abstract: A household device, in particular a refrigeration device, includes an electronic control device configured to control at least one function of the household device, an input device connected to the control device, having at least one input and being configured to supply an assigned control signal to the control device, based on a manual actuation of the at least one input. An input locking device, in its locked state, is configured to prevent controlling of the function of the household device, despite the at least one input being actuated, and in its unlocked state, is configured to permit controlling of the function of the household device when the at least one input is actuated. The input locking device is configured and/or constructed for shifting the input locking device into the locked state, after the at least one input has not been actuated over a predefined time period.

Abstract: A reciprocating pump for pumping a fluid, especially for pumping a fluid such as UV ink which is subject to solidification when exposed to frictional forces. The pump has an internal displacement chamber with an inlet, and outlet, and a plunger which is reciprocally movable in the chamber. The plunger reciprocates through an axial passage in the housing at one end of the chamber, the passage being sized to receive the plunger with a clearance fit. First and second seals are positioned in the axial passage. Each seal is annular in shape and extends between the plunger and housing in sealing contact therewith. The pump housing is free from a bearing which contacts the plunger or guides its motion, such that the sealing contacts between the plunger and seals are the only contacts of the plunger in the housing.
