Description

    Field of Invention
  • This invention relates to cooling devices used for storing foodstuffs.
    • Prior Art
  • As is known, a refrigeration cycle is usually carried out by means of a compressor, condenser, capillary tube, and evaporator in cooling devices used in storing food products. Hot fluid, output from the compressor in pressurized form is condensed in the condenser, thereby giving off some of its heat and pressure; thereafter it is passed through capillary tubes and delivered to the evaporator under very low pressure. The evaporator is employed for cooling the device interior (i.e. internal volume), so that as refrigerant passes through it, it evaporates due to its low pressure and the temperature of the internal volume, resulting in cooling on the evaporator surface. This cooling effect aids in cooling down the device's internal volume. At the end of the cycle, the refrigerant is guided back to the compressor and all processes are repeated.
  • In order to maintain the temperature stability of the internal volume that is brought to low temperatures in these cooling devices, the refrigeration cycle is kept continuing and some heat insulations are made on the device. Particularly for lowering the energy consumption due to the refrigeration cycle, the insulation thickness and the amount of refrigeration fluid used in the device may be increased, and more efficient compressors may be preferred. It is further devisable to change the size of components (e.g. evaporator, condenser, etc.) used in the refrigeration cycle. Refrigerants and insulation materials used for this purpose, however, are harmful against the environment; hence any increase in their amounts creates a further potential damage against the environment.
  • With respect to known and widely-applied techniques, air is sucked from the evaporator surface by means of a fan unit and is distributed into the internal volume of the device, such that the device interior is uniformly cooled down with the cooled evaporator surface. As a relevant example, the published patent application KR20020015242 discloses an arrangement, in which a fan providing in-refrigerator air circulation is disposed on an evaporator. According to this arrangement, the fan sucks a mass of air from the evaporator surface, so that the air mass is uniformly distributed within the refrigerator. The published patent application KR20010065919 , in turn, discloses an arrangement, in which a mass of air mass sucked from an evaporator surface by means of a fan is distributed within a cooler with the aid of a second fan.

    Description of Invention
  • The cooling device (A) used for storing food products (either by refrigerating or freezing the same) according to the present invention, as illustrated in figures 1 and 2, is developed to provide energy saving and enhancement of refrigeration efficiency. Said device (A) comprises a compressor (1), condenser (2), evaporator (3) units to conduct the refrigeration cycle known in the relevant art. It is aimed with the present invention to cool the internal volume (5) of the device (A) in a more efficient manner. The device (A) internal volume (5) is provided with fixed or removable shelves (6), formed for placing food products thereon. The internal volume (5) may also be separated into different compartments (e.g. cooling, freezing compartments, vegetable compartment etc.; not illustrated in figures). At least one door (12) (e.g. cooler and freezer compartment doors) is provided to give access into the internal volume (5). A heat-insulation material is provided at the device (A) body (13) and door (12) to prevent heat exchange between the internal volume (5) and the exterior.
  • With the air blowing unit (8) of the device (A) according to the present invention, air at a high flow rate is hit onto the evaporator (3) and it is distributed over the evaporator (3) surface, such that heat transfer (i.e. amount of heat which the evaporator absorbs from the internal volume) occurring at the evaporator (3) is increased. The refrigerant (3) in the evaporator evaporates, with the heat it takes, into the gaseous phase. With an increase in the heat absorbed by the refrigerant in the evaporator (3) while it changes phase with the aid of air guided to the evaporator, more efficient use is made from the refrigerant. The amount of heat which the refrigerant absorbs from the internal volume (5) is increased and the operation time of the compressor (1) is reduced, therefore energy consumption is decreased by 28-35% as compared to the prior art, as determined from the results of tests performed. This fact means that advancement is achieved by at least one class in refrigerator energy classes according to European (EU Directive 94/2 EC) standards. Additionally, by creating an angle of 30 degrees at least, between the direction of air guided onto the evaporator (3) and the evaporator (3) surface, most efficient cooling is obtained (according to the results of tests performed).
  • As an exemplification of the present invention, at least one internal wall (4) of the cooling device (A) is closed partially or entirely with at least one plate (7), and at least one evaporator (3) is disposed in the gap (11) remaining between the wall (4) and the plate (7) (referring to Figure 1, the evaporator (3) is illustrated to be placed at an internal wall (4) of the device (A)). The internal wall (4) may be any wall on the device body (13) and/or door (12) (a vertical rear wall is shown in the figures for this purpose). According to this sample embodiment, said plate (7) separates the evaporator (3) from the internal volume (5). The evaporator (3) may either be placed on the internal wall (4) or plate (7), or be situated so as to separate said gap (11) into two. The plate (7) is particularly made from a material with low heat conductivity (heat insulation). Thus, any frost formation thereon is prevented. Therefore no frosting occurs in said gap (11), except the outer surface of the evaporator (3). For this reason, the plate (7) can be kept as close as possible to the evaporator 83) so that the useable space of the device (A) interior (5) is increased.
  • In this sample embodiment (A), air is guided onto the evaporator to cool down the device (A) interior (5), such that air cooled down here is propagated through said gap (11) and is fed into the internal volume (5) (air flow is illustrated by dashed arrows) through at least one hole (9) provided on the plate (7) and/or on at least one wall (4) (the hole is illustratively shown on the plate (7) in Figure 2). At least one air blowing unit (8) (situated at a certain distance to the evaporator (3) surface) used to guide air onto the evaporator (3) sucks air from the internal volume (5) and guides it directly onto the evaporator (3) (to any region on the evaporator (3), e.g. to a region on the evaporator (3) at a certain distance to the center of the evaporator (3) surface). It is one of the preferred embodiments according to the present invention to create an angle of 30 degrees at least, between the direction of air guided onto the evaporator (3) and the evaporator (3) surface.
  • The air blowing unit (8) may be situated on the plate (7) (as representatively illustrated in Figure 1), on the internal wall (4), or on the evaporator (3). The air blowing unit (8) may suck and blow the air either coming from at least one hole (10) on the plate (7); or, if the unit is situated on the internal wall (4), from at least one channel (not illustrated in figures), which may be provided on at least one internal wall (4) and connected with the internal volume (5). Said air blowing unit (8) may be a fan unit or an air pump.
