Definitions
- the invention relates to a washing machine.
- the invention relates to a washing machine.
- Washing machine comprising a housing, a tub for holding
- washing liquid a drum rotatably mounted in the tub for receiving laundry, a metering device which is designed, at least one cartridge
- the housing housing the tub, the drum and the metering device and having a housing flap which is arranged in front of the at least one cartridge which can be arranged in the metering device.
- Such a washing machine has a vacancy sensor which is designed to detect an vacancy of the cartridge arranged in the metering device.
- the vacancy sensor only recognizes the vacancy of the cartridge when the cartridge is empty. This can result in a wash cycle with little or no detergent. This will degrade the washing performance.
- the invention therefore presents the problem of providing a guard machine in which the cartridge can be prevented from becoming empty in good time.
- the housing flap is at least partially transparent or has at least one opening, so that when the at least one cartridge is arranged in the metering device, a fill level of the at least one cartridge is at least partially visible from outside the housing.
- arranged cartridge can be translucent or transparent.
- the invention is the The basic idea is that the fill level of the cartridge arranged in the metering device is visible from outside the housing.
- the cartridge itself is not part of the subject matter of claim 1. Rather, it can be arranged by a user in the washing machine if required. If no cartridge is arranged in the metering device, a part of the metering device, in particular a receiving device of the metering device, which is designed to receive the at least one cartridge, is visible from outside the housing.
- the housing houses the tub, the drum and the metering device and has a housing flap which is arranged in front of the at least one cartridge which can be arranged in the metering device means that the housing together with the housing flap surrounds the above components, as is customary with front and top loaders .
- Position and direction information refer to the operational installation position of the
- the housing flap can be made of a transparent plastic.
- the housing flap has at least one viewing window which is designed as a transparent window or an opening. It is more preferred
- the housing flap preferably has an opaque plastic in which a transparent plastic is integrated like a window.
- the housing flap preferably has a number of viewing windows which corresponds to a number of cartridges which can be arranged in the metering device. Each cartridge that can be arranged in the washing machine is preferably each assigned a viewing window and vice versa.
- Each viewing window is preferably arranged in such a way that the viewing window is completely filled when a cartridge filled with the detergent is assigned to it, that the viewing window is filled the less, the less detergent the cartridge is assigned to it, and that the viewing window is not filled as soon as the cartridge has a detergent level below a predetermined level.
- the predetermined level is preferably a level of the detergent in the cartridge that is sufficient, less than five
- Wash cycles preferably less than three wash cycles. This gives the user sufficient time to have a new cartridge ready until the empty cartridge is empty.
- Another advantage is that the fill level of the detergent is visible to the user and not only the vacancy is recognizable.
- a scale is assigned to each viewing window, which is designed to indicate a scaled fill level of the respective cartridge.
- the scale continues to support the user in the detection and evaluation of the fill level of the Detergent in the cartridge.
- the scale can be a scale that is assigned to two viewing windows together.
- the scale can appear as one or more besides that
- Lines extending viewing window may be formed, to which numbers are assigned, for example, as information for a quantity of detergent in the cartridge.
- the scale is designed to indicate the fill level of the amount of detergent contained in the cartridge as a percentage or to indicate the number of possible washing processes with the amount of detergent contained in the cartridge in accordance with the fill level.
- the metering device is preferably designed to accommodate at least one elongated cartridge.
- the cartridge can utilize installation space without this greatly affecting the size of the tub.
- the metering device is preferably designed to receive the at least one elongated cartridge in an oblique position along its longitudinal extent.
- the detergent is directed into a depression at a low fill level, namely the lowest point of the cartridge, and can be metered in effectively even at a low fill level.
- the elongated cartridge is preferably arranged such that it tilts downwards in the direction of the interior of the washing machine.
- the washing machine also has one
- Lighting device which is arranged, aligned and designed such that it illuminates the at least one cartridge when the at least one cartridge is arranged in the metering device. This will increase the visibility of the fill level of the
- Detergent in the cartridge from outside the housing continues to improve. This means that not only the fill level but also the presence of a cartridge in the
- Dosing device recognizable from outside the housing.
- Lighting device arranged behind the cartridge.
- the lighting device is arranged, aligned and designed to light up in the direction of the viewing window.
- the lighting device can be designed to illuminate the cartridge only when the washing machine is in operation.
- the at least one lighting device is preferably designed as at least one light-emitting diode. This is an inexpensive and durable lighting device.
- the at least one cartridge is in the
- Dispensing device arranged and designed to be translucent.
- washing machine includes a purely washing machine and a combination device such as a washer dryer.
- the washing machine is preferably a front loader.
