Problems solved by technology

However, it has been found here that such baffles can exacerbate the problem rather than alleviate it if the baffles are not hermetically sealed, as moisture that condenses tends to accumulate in the narrow spots around the baffle (where it is also mostly sheltered from the wind and barely re-evaporates), however, this moisture limits the freedom of movement of the baffles in freezing conditions and in this way only creates more flow shelters at which condensation can accumulate

Embodiment Construction

[0021] figure 1 The domestic refrigerating appliance shown in is a combination appliance having a normal refrigerator compartment 2 in the upper part of the body 1 and a freezer compartment 3 in the lower part. In the horizontal partition wall 4 between the compartments 2 , 3 is accommodated an evaporator chamber 5 with an evaporator 6 (usually in the form of a laminate) and a defrost heater 7 .

[0022] On the bottom of the conventional refrigerated compartment 2 - adjacent to the door 8 closing the conventional refrigerated compartment 2 - an air outlet 9 is formed, from which a short suction channel 10 extends inside the partition wall 4 to the evaporator compartment 5 front edge. On the rear edge of the evaporator chamber 5 a ventilation device 11 is arranged; from this rear edge a pressure channel 12 extends upwards along the rear wall 13 of the body 1 up to the air inlet of the normal refrigerated compartment 2 in the rear upper corner of the body 14. The pressure cha...

Abstract

The invention relates to a refrigerating device having at least one storage chamber (2) which can be closed by a door (8); an evaporator chamber (5), which is arranged at a lower level than the storage chamber (2), contains an evaporator (6) that is operated intermittently, and communicates with the storage chamber (2) via a suction channel (10) and a pressure channel (12) that rises to an inlet (14) of the storage chamber (2); and a ventilator (11) for driving the air circulation between the storage chamber (2) and the evaporator chamber (5). The ventilator (11) is functionally coupled to thedoor (8) in order to run on a level of power which is sufficient to prevent an air flow directed from the storage chamber (2) to the evaporator chamber (5) in the pressure channel (12) while the door(8) is open during a period of inactivity in which the evaporator (6) is not operational.

Description

technical field [0001] The invention relates to a refrigerating appliance having at least one first storage chamber, which can be closed off by a door, and a ventilation device which drives the storage chamber and the evaporator chamber for cooling the storage chamber. Air circulation between chambers. In order to achieve a uniform temperature distribution in the storage chamber, in this refrigeration appliance the two chambers are communicated by two channels, wherein the inlet channel is arranged at a higher level than the outlet channel, through which fresh cold air passes The channel enters the storage chamber, through which the heated air flows back to the evaporator chamber. Background technique [0002] If the evaporator chamber is arranged at a lower level than the first storage chamber, a pressure channel must be provided which bridges the height difference between the evaporator chamber and the inlet. Such a pressure channel usually runs in the wall of the applia...
