Abstract

A refrigerator comprising a water conduit that is equipped with a socket for an exchangeable water filter and a monitoring unit for detecting the water throughput through the water conduit, said unit generating an alarm if the water throughput exceeds a threshold value. The monitoring unit can be deactivated if a water filter is mounted in the socket.

Claims (6)

1. A refrigeration device comprising:

a water supply line, a replaceable water filter adapted to be installed in the water supply line, a holder for the replaceable filter; a monitoring device for recording the water throughput through the water supply line and for generating a warning signal if the water throughput exceeds a limiting value; and an apparatus for deactivating the monitoring unit if the water filter is fitted in the holder; a sensor; the monitoring unit being connected to the sensor for detecting the type of filter fitted in the holder whereby the monitoring unit may be activated or not activated dependent upon the type of filter detected by the sensor, wherein upon at least one of detection of a first type of filter the monitoring unit is automatically active and detection of a second type of filter the monitoring unit is automatically inactive; wherein the first type of filter is an adsorption filter and the second type of filter is a particle filter.

2. The refrigeration device as claimed in claim 1 , wherein the monitoring unit includes an input for allowing at least one of deactivation of the monitoring unit and activation of the monitoring unit by a user.

3. The refrigeration device as claimed in claim 1 , wherein the sensor interacts with a different coding of the filter according to the type of filter.

4. The refrigeration device of claim 1 , wherein the monitoring unit includes an input for allowing deactivation of the monitoring unit and activation of the monitoring unit by a user.

5. The refrigeration device as claimed in claim 1 , wherein upon detection of a first type of filter, the monitoring unit is automatically active and upon detection of a second type of filter, the monitoring unit is automatically inactive.
