Embodiment Construction

[0020] figure 1 A part of a housing of a domestic appliance 1 designed as a washing machine 1 for washing laundry care is shown. The washing machine 1 comprises side walls 2 and 3 and a bottom element 4 . A water leakage collecting device 5 is formed in the base element 4 .

[0021] A water leakage collecting device 5 is formed in the base element 4 . as from figure 1 It can be seen that this collecting means 5 is formed by a recess in the bottom element 4 and thus takes the form of a sump. The collecting device 5 is bounded by a side wall 51 .

[0022] Furthermore, the collecting device 5 comprises a water-retaining wall 52 which is integrally formed in the base element 4 and thus also in the collecting device 5 . In the exemplary embodiment, the water-retaining wall 52 is curved and adjoins the side wall 51 of the collecting device 5 . The water-retaining wall 52 is formed as a protruding structure and thus extends upwards.

[0023] The collecting device 5 is divided ...

Abstract

The invention relates to a household appliance (1) for the care of laundry items, having a collecting apparatus (5) for leakage water which is arranged on the base (4) of the household appliance (1), and a float (81) which is arranged in the collecting apparatus (5) and is configured for making electrical contact with a switch (8) as a function of the water level (W) in the collecting apparatus (5), wherein the float (81) is arranged in a first part region (5a) of the collecting apparatus (5), which first part region (5a) is separated from a second part region (5b) of the collecting apparatus (5) by a water damming wall (52).

Description

technical field [0001] The invention relates to a household appliance, in particular a washing machine or a washer-dryer, for caring for washware, having a leakage collecting device arranged on the bottom of the household appliance and a float arranged in the collecting device, the float being configured to Depending on the water level in the collecting device, a switch is contacted and turned on. Background technique [0002] A domestic appliance is known from DE 199 36 420 B4 with a corresponding overflow device and a so-called water shut-off switch, by means of which the water shut-off switch is triggered when a certain amount of leakage water is collected in the collecting device and the float rises to trigger the water shut-off switch. The water shut-off switch can load the shut-off valve in the fresh water supply line into its closed position. [0003] A problem that can arise in disclosed household appliances of the type described is that in the case of relatively sm...
