Definitions
- Refrigeration device such as a refrigerator, a fridge-freezer or the like
- the invention relates to a cold appliance, such as a refrigerator, a fridge-freezer combination or the like, with a heat-insulating housing having at least one door and at least one heat exchanger serving as a condenser, and a collecting container for introducing melt water which occurs during the defrosting operation of the cold appliance
- a suction element formed at least from largely absorbent, hydrophilic material protrudes into the receiving space of the receptacle and is at least partially exposed to heat from the condenser
- the suction element is flexible, In terms of production technology, this can be easily brought up at least in the vicinity of the heat-dissipating surface of a condenser, such as, for example, a flat, flat or even a wound condenser, to increase the evaporation performance.
- the suction element also increases the evaporation surface for the melt water, which results in an additional increase the evaporation rate results
- the evaporation performance is particularly favorably influenced if, according to a preferred embodiment of the object of the invention, it is provided that the suction element is brought into heat-conducting contact with the condenser at least in sections.
- the suction element is brought into heat-conducting contact with the condenser at least in sections.
- the suction element with its end projecting into the receiving space of the collecting container is arranged at a minimum distance above the bottom of the collecting container
- the suction element has an areal extension, with one side edge of the area protruding into the receiving space of the collecting container.
- the flat design of the suction element results in increased suction power due to the surface side edge available as the suction edge.
- the flat design of the suction element results in a significant enlargement of the evaporation surface serving to increase the evaporation performance, which can be coupled to the condenser particularly intensively with a flat, heat-conducting contact to the condenser with regard to highly efficient melt water evaporation.
- the flat suction element is particularly simple if, according to a next advantageous embodiment of the object of the invention, it is provided that the suction element is rectangular and projects with one of its narrower rectangular side edges into the receiving space of the collecting container.
- the rectangular design of the suction element enables a condensate collecting container that is optimized with regard to reduced length dimensions without adversely affecting the suction and evaporation effect of the suction element, since with the rectangular design of the suction element, in particular in cooperation with a planar evaporator, there is the possibility of its overall height at least partially for to use a heat transfer to the suction element.
- a suction element is particularly advantageous if, according to a next advantageous embodiment of the object of the invention, it is provided that the suction element is at least largely formed from cellulose material.
- a particularly simple and efficient use for a suction element results in a refrigeration device if, according to a further preferred embodiment of the object of the invention, it is provided that the refrigeration device is equipped with a flat condenser on the back of the device opposite the door and below it a machine room with a Has a refrigerant compressor and a condensate collecting tray serving as a collecting container, into which the suction element, which is at least approximately in heat-conducting contact with the condenser, projects with a minimum distance from the bottom of the tray.
- the suction element can be attached to the refrigeration device in a particularly production-friendly and thus inexpensive manner, and at the same time with particularly favorable heat transfer from the condenser to the suction element.
- the suction element has a flat side edge, the length of which is at least essentially matched to the larger dimension of the condensate collecting pan.
- the suction element can be replaced particularly easily in the event of a decrease in suction power or mold contamination if, according to a last preferred embodiment of the object of the invention, it is provided that the suction element is detachably fixed in at least largely heat-conducting contact on the condenser.
- a section of a cold appliance designed as a table-top refrigerator 10 with a warm-insulating housing 11 is shown, in sections, in a simplified illustration.
- a machine room 13 On its rear end 12, on its lower end section, a machine room 13 is recessed with respect to the rear side 12, within which a refrigerant compressor 14 is fixed on a support rail 15 extending across the width of the machine room 13.
- the refrigerant compressor 14 carries, at its upper end section opposite the support rail 15, a condensate collecting tray 16, for example molded in one piece from plastic, into which the melt water accumulating during the defrosting operation of the table refrigerator 10 is introduced
- Thawing water collecting tray 16 has a bottom wall 17 and a side wall 18 arranged circumferentially on its edges, which together with the bottom wall 17 delimits a thawing water receiving space 19
- a flat condenser 20 is provided on the rear side 12, which is provided in the present case as a so-called wire condenser with a meandering pipeline 21 and wire rods 22 arranged to cross it.
- One of the horizontal sections of the pipeline 21 has a flat, in the form of a rectangle in DIN A-4 size, made of absorbent, hydrophilic material, for example based on cellulose 22 formed heat exchange surface of the condenser 20 on.
- the rectangular suction element 23 extends with its end section 24 facing the compressor 14 into the condensate receiving space 19, the end section 24 with its side edge 25 forming the free end at a distance above the floor wall manure 17 is arranged, so that the condensate receiving space 19 must always be filled with a certain amount of mildew water in order to be able to wet the suction element 23.
- the length of the side edge 25 is matched to the length of the longer shell side of the condensate collecting pan 16, so that the suction element 23 over the Entire length of the condensate drip tray 16 is able to absorb melt water if the melt water level within the condensate holding space 19 has exceeded a minimum height reaching to the side edge 25.
- the melt water is capillaryly passed on via the end section 24 to the section of the suction element 23 which is in direct thermal contact with the condenser.
- the melt water is evaporated by the heat of the condenser 20 on the suction element 23 on its surface.
- Suction elements with basis weights of 150 g / m 2 or 220 g / m 2 or 330 g / m 2 with components made of wood pulp, cellulose short cut fibers, polyester fibers and melt fibers have already given good results with regard to a significant increase in the evaporation capacity for the melt water.
- an impregnation of the suction element to avoid mold formation has proven to be favorable.
