Abstract

The present invention relates to a cooling device (1) wherein the condensation on the bottom surface of the vegetable container lid (6) is reduced by an all around air circulation encircling the vegetable container (5).

Description

Description A COOLING DEVICE
[001] The present invention relates to a cooling device which comprises a vegetable container.
[002] The cooling devices comprise a refrigerating compartment where food and beverages are stored, a freezing compartment where food is stored by freezing, and a vegetable container situated in the refrigerating compartment where fruit and vegetables are stored. The vegetable container is separated from the inner volume of the refrigerating compartment by a vegetable container lid placed on top of it. The air circulation between the refrigerating compartment and the vegetable container is kept limited to prevent the food stored in the vegetable container from losing moisture by dehydrating. Therefore a temperature difference is formed, although small, between the inner volume of the refrigerating compartment and the vegetable container. Condensation occurs on the inner surface of the vegetable container as a result of the temperature difference. Condensation adversely affects the storage life of the food kept in the vegetable container.
[003] In International Patent Application no. WO 02/081987, a circulation fan is installed in a housing just behind the vegetable storage chamber and the air sucked in from the refrigerating chamber by this fan having a lower temperature than that of the vegetable storage container is circulated around the vegetable storage container thus lowering the temperature in the vegetable storage container.
[004] In European Patent no. EP 0 719 994, the vegetable storage container is separated from the refrigerating chamber inner volume by a lid. The lid comprises air passage holes in the portion close to the refrigerator back wall. The air flowing through the air holes circulate as two parallel air currents above and below the vegetable storage container.
[005] The aim of the present invention is to achieve a cooling device wherein condensation is reduced and the temperature is controlled inside the vegetable container.
[006] The cooling device designed to fulfill the objective of the present invention is illustrated in the attached figures, where:
[007] Figure 1 - is the schematic view of a cooling device.
[008] Figure 2 - is the schematic view of a cooling device in an alternative embodiment of the present invention.
[009] Elements shown in the figures are numbered as follows:
1. Cooling device
2. Cabinet
3. Door 4. Compressor
5. Vegetable container
6. Vegetable container lid

8. Air passageway

[010] The cooling device (1) comprises a cabinet (2) into which food and beverages are stored, a door (3) separating the cabinet (2) from the outer environment in a leak-proof way and allowing access inside, a compressor (4) providing the refrigerating cycle, a vegetable container (5) positioned inside the cabinet (2), a vegetable container lid (6) situated over the vegetable container (5) separating the vegetable container (5) from the interior volume of the cabinet (2), an opening (7) situated between the vegetable container lid (6) and the back wall of cabinet (2) allowing the flow of air, an air passageway (8) connected to the opening (7), positioned between the vegetable container (5) and/or the vegetable container lid (6) and the cabinet (2), an air passageway outlet (9) and a door air duct (10) situated on the door (3), providing the transfer of the air sucked from a point in the interior volume of the cabinet (2) to another point.
[011] The door air duct (10) comprises a door air duct inlet (11) situated approximately opposite the air passageway outlet (9) sucking in the air outflowing from the air passageway (8), and a door air duct outlet (12) situated a little over the level of the vegetable container lid (6) so as to enable blowing the air received from the air passage way (8) over the vegetable container lid (6).
[012] The cooling device (1) comprises a fan (13) positioned inside the air passageway
(8) or the door air duct (10), providing guiding of the air from the air passageway (8) to the door air duct (10), blowing the air from the air passageway outlet (12) over the vegetable container lid (6), and again sucking air with the suction effect created in the air passageway (8) via the opening (7) to complete the circulation all around the vegetable container (5), balancing the temperatures above and below the vegetable container lid (6), consequently reducing the condensation formed on the bottom surface of the vegetable container lid (6). The fan (13) is preferably positioned at the door air duct inlet (11). The fan (13) is operated when the door (3) is closed.
[013] The fan (13) operates in intervals in order to increase the air circulation around the vegetable container (5). When the fan (13) operates, the air in the air passageway (8) is sucked and guided into the door air duct (10) since the door air duct inlet (11) is almost opposite the air passageway outlet (9). The air flowing through the door air duct (10) is blown into the cabinet (2) through the door air duct outlet (12). The air blown from the door air duct outlet (12) is guided to the cabinet (2) back wall sweeping the vegetable container lid (6) since the door air duct outlet (12) is positioned a little over the level of the vegetable container lid (6). The air guided to the cabinet (2) back wall, passes through the opening (7) and reaches the air passageway (8). The air sucked in from the air passageway (8) contacting the base of the vegetable container (5) passes over the vegetable container lid (6) providing the balancing of temperatures above and below the vegetable container lid (6) and consequently reduces the condensation on the bottom side of the vegetable container lid (6).
[014] In another embodiment of the present invention, the fan (13) is positioned at the air passageway outlet (9).
[015] In another embodiment of the present invention, the fan (13) is positioned at the door air duct outlet (12).
[016] In yet another embodiment of the present invention, the fan (13) operates when the door (3) is closed and the compressor (4) is functioning.
[017] In yet another embodiment of the present invention, when the door (3) is closed and the compressor (4) is functioning, the fan (13) is operated for a preset time period at preset intervals determined by the producer.
[018] In yet another embodiment of the present invention, the cooling device (1) compris es a temprature sensor (14) positioned in the air passageway (8). The fan (13) operates when the temperature detected by the temprature sensor (14) goes above a preset value.
[019] In yet another embodiment of the present invention, the cooling device (1) comprises two temprature sensors (14), one positioned in the air passageway (8) and the other in the vicinity of the vegetable container lid (6). The start and stop timings of the fan (13) are determined by comparing the preset limit value with the difference in temperatures detected by the temprature sensors (14).
[020] In another embodiment of the present invention, the door air duct outlet (12) is built inclined towards the vegetable container lid (6) so that the air blown over the vegetable container lid (6) by the fan (13) contacts the vegetable container lid (6) more efficiently.
[021] In yet another embodiment of the present invention, a deflector is situated at the door air duct outlet (12) so that the air blown over the vegetable container lid (6) by the fan (13) contacts the vegetable container lid (6) more efficiently.
[022] The storage life of food in the vegetable container (5) is extended with the reduction of the condensation on the bottom surface of the vegetable container lid (6) by achieving an all around air circulation encircling the vegetable container (5).
