Problems solved by technology

Defective filter cartridges can cause the machine to be supplied with an insufficient amount of water or incorrectly pre-treated water, which can lead to negative effects such as limescale formation, or even cause the machine to malfunction
If the correct type of filter cartridge is thought to be used but is not, the machine control system cannot set the scheduled maintenance intervals in time
The use of insufficient filter cartridges creates problems not only in terms of operational reliability of the machine, but also in guarantees, etc.

Embodiment Construction

[0044] Correspondingly, figure 1 Schematically shows a perspective top view of a tank 1 for an appliance using water, in particular a household appliance, with a filter cartridge connection 8 ( image 3 ) and a substantially horizontally oriented appliance connection 3 . This type of box is also known as a "drawer box" and is preferred for applications where space is limited. An advantage of such a drawer box is that the box can be inserted into the appliance from the front and removed from the appliance. The connection of the appliance to the water treatment unit is usually, but not necessarily, established by a suction connection line, the appliance connection 3 being connected in a water-conducting and closed manner to the outside when the tank 1 is inserted into the appliance (not shown) to the suction connection line.

Abstract

The present invention relates to a tank for water-bearing appliances, in particular domestic appliances such as beverage machines, in particular coffee machines, drinking-water dispensers, boiling and baking appliances, steam appliances, in particular steam irons, steam cleaners, pressure washers, air purifiers and conditioners or the like, having a filter cartridge connection (8). Said tank is distinguished in that an appliance connection (3) which can be connected by a predominantly horizontal insertion movement is connected to connection elements which are provided for a filter cartridge (2) which can be inserted into the inside of the tank (1). The present invention also relates to a filter for use with a water tank of this kind and to an appliance in which a water tank of this kind can be used.

Description

technical field [0001] The invention relates to a tank with a filter cartridge according to the preamble of claim 1 . Background technique [0002] In various machines such as coffee or espresso machines (Espressomaschinen), a water tank is provided to store liquid, in the case of coffee or espresso machines, water, where a filter cartridge can be inserted into the tank for disposal in the machine Pre-treat / purify the water before. Known filter cartridges have an inlet in the lower region through which water is drawn from the associated machine. Here, the water enters the machine via the filter bed, via a filter cartridge connection, to the corresponding appliance connection of the water tank, which is usually designed as a suction connection. [0003] In commercially customary embodiments, such an appliance connection of the water tank is usually formed on the bottom side. On the one hand, this allows the tank to be easily emptied, and on the other hand, such tanks, whic...
