Embodiment Construction

[0060] through as figure 1 and figure 2 The illustrated example of a dishwasher 1 here explains and partially demonstrates the invention, however, other washing machines, such as washing machines, may also fall within the scope of the invention.

[0061] figure 1 A perspective view of a dishwasher 1 is shown with a container 6 , a door 16 for opening when crockery needs to be placed in the dishwasher 1 or when it needs to be removed from the dishwasher. The dishwasher 1 comprises two drawers 18', 18", an upper drawer 18' and a lower drawer 18". The drawers 18', 18" are used to conveniently place and remove dishes and keep them in place during washing. The dishwasher further comprises a wash liquid distribution arrangement 4 which includes a spray arrangement 14 having at least Two rotating spraying arms 14a, 14b, one rotating upper spraying arm 14a and one rotating lower spraying arm 14b. After being sprayed onto the tableware, the washing liquid is collected in the funnel...

Abstract

The invention relates to a heating unit (8) for a washing machine (1), comprising a housing (22), a pump (20) for pumping washing liquid through the housing (22), a fuse (36), a heat conduction element (30) for transferring heat to the washing liquid in the housing (22), and a temperature regulator (34), the temperature regulator is in the washing liquid in the housing (22) Energy in the form of heat can be supplied to the heat conducting element (30) when the target temperature is below a first temperature limit. The fuse (36) and the temperature regulator (34) are arranged to conduct heat with the heat conducting element (30), the fuse (36) is electrically connected to the temperature regulator (34) and is configured for use in the The power supply to the thermostat (34) is triggered and stopped when the washing liquid in the housing (22) reaches the trigger temperature of the fuse (36). The heating unit (8) includes an electronic temperature sensing device (38), which is electrically connected to the fuse (36) and the temperature regulator (34), and the electronic temperature sensing device (38) Arranged for conducting heat with the heat conducting element (30) and for detecting and recording the temperature of the washing liquid passing through the housing (22) over time in order to provide information about the operating state of the washing machine.

Description

technical field [0001] The present invention relates to the field of washing machines, in particular dishwashers, and their increased safety and long-term reliability. In particular, the invention relates to improving the protection monitoring of washing machines over time and to improving the safety of fuses in heating units. The washing machine according to the invention allows reducing the service call rate and thus reducing the costs for running the washing machine while increasing reliability. Background technique [0002] Dishwashers have been used for many years, operating under harsh conditions, sometimes with heavy dirt and sometimes aggressive washing liquids. The wash solution is usually a mixture of detergent, water, and food / waste residue. Dishwashers generally comprise a cleaning container comprising one to several spray arms which rotate when the dishwasher is in use. Typically, water is supplied via an inlet valve connected to a fresh water pipe (usually m...
