Description

REFRIGERATOR THAT HAS AN AIR CIRCULATION SYSTEM TECHNICAL FIELD The present invention relates to a refrigerator having an air circulation system, and more particularly to a refrigerator having an air circulation system having a cold air passage and an oscillating wing system capable of circulating air cold towards a refrigeration compartment. BACKGROUND OF THE INVENTION As shown in Figure 1, a conventional refrigerator is constituted by mounting a door of the freezer compartment 6 and a door of the refrigeration compartment 7 on a refrigerator body 4 on a thermally insulated structure that forms a freezing compartment 2 and a cooling compartment 3, which are divided from one another by an intermediate partition wall 1 between them. A compressor 11 is installed in an engine compartment 11M which is placed below the cooling compartment 3, a condenser and a capillary tube (not shown) are mounted inside the body 4, or are placed in the machine compartment 11M, and an evaporator 12 is mounted on the rear wall of the freezing compartment 2. The components are connected to each other by refrigerant tubes (not shown) to perform a refrigeration cycle. A fan 13 is placed to force cold air 5 from the evaporator 12 into the freezing compartment 2 and into the cooling compartment 3, above the evaporator 12. In order to guide the flow of the cold air, a grid 14 is placed before of the fan 13, and a cold air duct 15a is placed in ^ < - the rear wall of the refrigeration compartment 3. Here, the numeral 19 indicates a control damper for controlling the amount of cold air that is introduced in the refrigeration compartment 3, and the numeral 8 indicates the shelves for receiving food products . 15 As a method of supplying cold air to the refrigeration compartment, a conventional refrigerator generally adopts a method of cold air discharge rack by shelf. As shown in Figure 2, in this method, a plurality of cold air discharge openings 16a, which are provided for several areas divided by the shelves 8, in a vertical direction over the cold air duct 15a, in such a way that the cold air is discharged towards the front, towards each formed area for the plurality of shelves 8.

In the cold air discharge method for the front rack, a uniform distribution of the cooled air is not achieved, since the areas in the direct path of the blown air receive more cooled air than the remote areas. The configuration of the food products 5 further contributes to this problem. As an example, a bulky food product near a cold air discharge opening blocks the flow of air, and consequently, this area receives less cooled air. There is still an additional problem in that, since the openings The cold air discharge 16a are perpendicular to the flow direction of the cold air going through the cold air duct 15a, only a small portion of the cold air from the evaporator 12 passes through the discharge openings of the air. superior cold air, but the Most of the cold air flows down through the cold air duct 15a, and is discharged into the cooling compartment 3 through the lower cold air discharge openings 16a. In accordance with the above, the food products on the shelves above the cooling compartment 3, can not maintain an appropriate cooling temperature, while the food items on the lower shelves are supercooled. There is another problem in which some newly stored food products may be at a significantly higher initial temperature and that the temperature in the cooling compartment. In this case, there is a need to concentrate the flow of cooled air to the hot / warm food product, to effect rapid cooling, as well as to prevent heating of the immediately surrounding food products. Conventional systems do not offer this compensating element. In accordance with the above, the situations described above contribute to an undesired condition where , ^ t- there may be significant temperature variation throughout the cooling compartment. In an attempt to distribute the cold air more evenly, a three-wall cold air discharge method has recently been developed. How I know shows in Figure 3, a refrigerator according to this method has a plurality of cold air discharge openings 16s on the side walls of the refrigerator. / - cooling compartment 3, as well as the cold air discharge openings 16a on the rear wall of the cooling compartment 3, in order to discharge cold air from the side walls as well as from the rear wall. However, this refrigerator fails to provide uniform air flow through the entire cooling compartment. That is, they still exist < "areas, such as corners, that are not directly exposed to the flow of cooled air." Also, this refrigerator does not offer elements to concentrate the flow of cooled air in a specified area depending on the detected condition of the cooling compartment. The above shortcomings of conventional refrigerators are especially clear in the event that higher temperature food products are stored in remote areas such as > / wPj superintendent skis or cooler compartments. Since refrigerators of a larger capacity suffer the above problems in a more remarkable way, and since the demand of the consumer of these refrigerators, the need for. Solving the above problems has become increasingly important.

SUMMARY OF THE INVENTION In accordance with the foregoing, it is an object of the present invention to provide a refrigerator capable of maintaining a uniform temperature over the entire volume of a cooling compartment, by uniformly dispersing the cold air evaporated in multiple directions. It is a further object to provide a refrigerator capable of achieving concentrated refrigeration over a specified area of the compartment, depending on the temperature detected within a plurality of specified areas of the refrigeration compartment. In accordance with the convenient features of the present invention, there is provided a refrigerator with an air distribution apparatus positioned on a wall of a refrigeration compartment, an air guide element placed in the air distribution apparatus in a vertical manner , and for dividing the volume of cold air introduced from the upper portion of the air distribution apparatus, and an air distribution element placed on the front of the air guide element, and for horizontally discharging the air divided through a plurality of openings formed in the front area of the air distribution apparatus.

Alternatively, a refrigerator is provided with an air distribution apparatus placed on a wall of a refrigeration compartment, and an air distribution element placed in the air distribution apparatus, for horizontally discharging a divided volume of air of the cold air introduced from the upper portion of the air distribution apparatus, through a plurality of openings formed in the front area of the air-conditioning apparatus. -w.J air distribution.

DETAILED DESCRIPTION OF THE PREFERRED MODE Figures 4 to 15 illustrate different embodiments of a cold air distribution apparatus having an air guide element. In Figure 4, the _. *) refrigerator is comprised of a body 4 protected by an insulating material comprising a freezing compartment 2 and a cooling compartment 3, which are divided by an intermediate wall 1. In addition, the respective compartments 2, 3 are equipped with doors 6, 7 on the front side of the compartments 2, 3. In the refrigeration compartment 3 a plurality of shelves 8 for placing food products are installed. In the upper portion of the cooling compartment 3, the third is formed compartment 9 to allow food products to be stored within a temperature scale in relation to the individual characteristics of the specific food products. A compartment of vegetables 10 is formed in the lower part of the refrigeration compartment 3. A compressor 11 is installed in an 11M engine compartment, and a condenser and a pressure reducing device, not shown, are installed in the wall of the body 4, or in a compartment of motor 11. In addition, the evaporator 12 is mounted on the rear wall of the freezing compartment 2. All the components are interconnected by a refrigerant pipe (not shown) to perform the refrigeration cycle. A fan is installed above the evaporator 12 _.-) 13 for forced blowing of the cold air generated from the evaporator 12 towards the freezing compartment 2 and the cooling compartment 3. To guide the cold air, a grid 14 is mounted in front of the fan 13. On the rear wall of the cooling compartment 3, it assembles a cold air distribution apparatus 17 having a passage of cold air and discharge openings which will be explained later. Accordingly, the cold air generated by the evaporator 12 is divided between the freezing compartment 2 and the storage compartment. refrigeration 3. The numeral 5 is a recess for housing the cold air distribution apparatus 17. As shown in Figure 5, the cold air distribution apparatus 17 is installed in the central portion of the rear wall 3 of the compartment from refrigeration 3. An upper portion of the air distribution apparatus 17, is placed behind the third compartment 9, while a middle portion and a lower portion of the air distribution apparatus 17 are placed behind the area of the refrigeration compartment 3, excluding the third compartment 9 and the vegetable compartment 10. That is, the upper end of the air distribution apparatus 17 is positioned adjacent to the intermediate wall 1, and the lower end thereof is placed adjacent to the vegetable compartment • * > . , d 10. The entire height of the air distribution apparatus 17 is approximately equal to the height of the cooling compartment 3 plus the third compartment 9. The cold air distribution apparatus 17, as shown in Figure 6, comprises a front plate 24 5 made of a synthetic resin, a back plate 25 which is made of insulated material, and is assembled with the front plate 24, a seal plate 34 covering the rear face of the back plate 25. A set is provided of a cold air distribution element of the present invention, which will be described later in different manners, or an oscillating wing 26 provided in a detachable manner on the face surface of the face plate 24. At the upper end of the oscillating wing 26, an engine 28 is provided to operate the oscillating wing 26. The engine 28 seated on a motor case 29, is installed - "on the upper portion of the front plate 24. At each lateral end of the l Engine 28, an internal lamp is mounted . The numeral 31 is a lamp cover for protecting the lamps 30. In the embodiment, since the motor 28 is mounted sealed in the upper portion of the oscillating wing 26, the humidity of the compartment can not penetrate the motor 28. Because moisture or condensed water flows downward due to the force of gravity, including 3 when there is moisture formation or condensed water, there is no concern for its penetration into the engine 28. In addition, there are less chances of penetration of humidity because the motor is housed by the box 29. There can not be an excess of cooling caused by the decrease in the speed of the motor due to the indirect contact of the humid air. Even when water penetrates, the water is immediately evaporated by the heat of lamps 30 mounted nearby, thereby eliminating the problem of the inoperability of the engine 28 due to the penetration of water, and in addition, the inaction of the oscillatory wing 26. Consequently, this has the advantage that there is never a decrease in the speed of the motor, with respect to a bad electrical contact, an insulation failure due to the penetration of humidity, or an excess of cooling due to the freezing of the water that penetrate. In the modality, a gear motor is used whose rotation speed is fixed, like the operating motor. However, a stepping motor can be used to control the rotational speed of the oscillating wing, as well as the forward and reverse rotation of the oscillating wing. The numeral 32, which was not explained, is a position detection switch for controlling the rotational position of the oscillating wing 26, which is "on / off" by means of a protrusion 33 provided at the upper end of the oscillating wing 26. The number of the position detection 32 corresponds to the number of the respective oscillatory wings that will be installed in accordance with the respective modalities. The numeral 27 is a grid removably assembled with the front plate 24 for the protection of the oscillating wing 26. The grid 27 prevents the food products housed in the compartment from impeding the rotation of the oscillating wing 26. In Figure 7, the upper portion of the air distribution apparatus 17 comprises an air passage 18 for guiding the flow of cold air generated from the evaporator 12, a screen plate 19 for regulating the volume of cold air fed to the cooling compartment 3 in accordance with the opening / closing of the display plate 19, and an engine 20 for operating the display plate 19. The temperature control used by these components is achieved by the same method of the conventional method. The numeral 21 is a screen cover and is formed integrally with the front plate 24 in the embodiment. The numeral 22 is a separator that is made of an insulated material. The thickened separator 22 prevents frost, which is caused by the amount of cold air through the air passage 18, from being generated on the outer wall of the screen cover 21. The numeral 23 is an air discharge opening that is provides on the upper portion of the faceplate 24, whereby cold air through the air passage 18 is discharged into the third compartment 9. In the embodiment, a pair of the discharge openings 23 are formed in the upper portion. of the front plate 24. Accordingly, the third compartment 9 maintains the temperature lower than the cooling compartment 3, since the distance of air travel from the air passage 18 to the air discharge opening 23 is shorter that from the air passage 18 to the middle and lower portion of the air distribution apparatus 17. The oscillatory wing 26 is placed in front of the middle and lower portions of the front plate 24. The conf The configuration of the oscillatory wing 26 of the present invention will be explained in detail later. The distribution apparatus 17 formed with a reinforced type, is removably mounted on the rear wall 3W, and it is more desirable that the front plate 24 be placed against a uniform surface with respect to the rear wall 3 of the refrigeration compartment 3 That is, as shown in Figure 6, the seal plate 34 adheres to the back side of the back plate 25 which is assembled with the front plate 24, and the oscillatory wing 26 and the grid 27 are assembled on the plate. 24, and then the motor 28 and the internal lamp 30 are assembled. Finally, the assembly is inserted in the rear wall 3 (Figure 5). Accordingly, in comparison with a prior art apparatus where many individual components are installed in the refrigeration compartment, respectively, the installation work using the components of the present invention is simpler. In Figure 8, the air distribution apparatus 17 comprises an air passage 15 and the openings 16A, 16B, 16C, which discharge air from the air passage 15 to the cooling compartment 3. The air passage 15 form in a longitudinal direction on the rear surface of the air distribution apparatus 17. The openings 16A, 16B, 16C are formed in a manner - penetrated in the air distribution apparatus 17 to connect the air passage 15 and the air compartment 15. refrigeration 3. The openings 16A, 16B, 16C are provided in an up and down manner along the vertical center line. The air passage 15 is provided with a first conduit 35 and a second conduit 36, each of which is configured adjacent to both vertical edges of the apparatus 17, concentrating on the openings 16A, 16B, 16C. The position of the respective openings 16A, 16B, 16C, corresponds to the space divided between the shelves 8 of the cooling compartment 3. The uppermost opening 16A is placed in 3 / 4H, the middle opening 16B in 1 / 2H, and the lower opening 16C in 1 / 3H, assuming that the height of the cooling compartment 3 is "H". Since the air passage 15 has first and second conduits 35, 36 on each vertical side, the wing member 26a is positioned in front of the opening 16, where the thickness of the air distribution apparatus 17 is thinner. Also, the protruding height of the dispensing apparatus 17 towards the cooling compartment 3 is lowered, thereby preventing the available volume of the cooling compartment 3 from decreasing. The upper portion of the first and second conduits 35, 36, expands towards both sides of the air passage 18, respectively, while the lower portion of the first and second conduits 35, 36 expands towards the vegetable compartment 10. The air, through the air passage 18 through the opening of the plate screen 19 (Figure 7), flowed in a branched manner towards the first and second conduits 35, 36. Most of the air is flowed down along the conduits 35, 36 to discharge into the refrigeration and vegetable compartments 3, 10. The remaining volume of the air is discharged into the third compartment 9 through the opening of download 23 (Figure 8). To guide the air flowing down to the cooling compartment 3, the air passage 15 comprises a first branch conduit 37 which is connected to the first conduit 35 and the opening 16, and a second branch conduit 38 which is connected to the second conduit 36 and opening 16. Accordingly, the air flowing along the first and second conduits 35, 36 is guided to the first and second branch conduits 37A, 37B, 37C, 38A, 38B, 38C, discharging from this way in the cooling compartment 3 through the respective openings 16A, 16B, 16C. The wide entrance of the branch conduits 37, 38 has the configuration in which the upper portions 37U, 38U are rounded, and the lower portion is configured with the flange 371, 372, 373 where the middle flange 372 is more extended outward (to the right and to the left of Figure 8) that the uppermost flange 371, and the lower flange 373 is more extended outwardly than the middle flange 372. Accordingly, since the first discharge air through the air passage 18 along the first and second conduits 35, 36, has a longer length to travel, the Air temperature is higher. The lower you go, , 0 greater amount of air is needed. The configuration of the branch conduits 37, 38 as above, is very useful to minimize the deviation of the air temperature with respect to the height of the refrigeration compartment 3. Furthermore, to feed the cold air in a 5 direction to the right or to the left to the cooling compartment 3, in the opening 16A comprising an upper portion 16U and a lower portion 16L, the upper portion 16U is formed out of phase towards the first branch conduit 37A with respect to the second branch conduit 38A, while the lower portion 16L is formed out of phase towards the second branch conduit 38A with respect to the first branch conduit 37A. The air through the opening 16A is discharged in each different direction, thereby causing a smooth discharge flow without the head-to-head collision towards the cooling-and-cooling compartment 3. Next, in the opening 16B adjacent to the opening 16A, the position of the upper and lower portions 16U ', 16L "is reversed with respect to that of the upper and lower portions 16U", 16L ".

The upper portion 16U 'is formed out of phase towards the first branch conduit 37B with respect to the second branch conduit 38B, while the lower portion 16L' is formed out of phase towards the second branch conduit 38B with respect to the first branch conduit 37B. Further, in the lower opening 16C, the position of the upper and lower portions 16U ", 16L" is reversed with respect to that of the upper and lower portions 16U ', 16L1. That is, the position of the upper and lower portions 16U ', 16L ', is the same as that of the upper portions and lower 16U, 16L of the upper opening 16A. In the above structure, the faster the air is discharged through the air passage 18, the higher the air temperature rises. The temperature of the air reached in the second branch conduit 38A, is higher than the air temperature reached in the first branch conduit 37A. In an alternative way, in the opening 16B, the temperature ratio is reversed. Also, in the aperture 16C, the temperature ratio is the same as in the uppermost aperture 16A. This slightly compensates the temperature deviation between the right and left side of the refrigeration compartment. Figure 9 shows a first embodiment of the oscillatory wing or air distribution element 126. The oscillatory wing 126 comprises a wing member 126a and a columnar member 126b. The wing member 126a is formed as a vertically extending plate, and integrally assembled with the columnar member 126b. The columnar member 126b extends along the longitudinal center of the wing member 126a which is used as the »0 revolving arrow of wing member 126a. The upper end of the oscillating wing 126 is connected with an output arrow of the pulse motor (Figure 6), to operate the oscillating wing 126. In addition, the protrusion 133 is provided at the upper end of the oscillatory wing 126, to control the rotational position of the oscillating wing 126, when a flow located in the cooling compartment 3 is required. It is more desirable that a pair of oscillating wings 126 be installed in the front of the openings 16A, 16B, 16C, to discharge 0 a uniformly the air entering into the cooling compartment 3 through the respective openings. One of the oscillating wings is oscillatingly placed in front of the openings, moving towards the right portion of the openings. That is, the longitudinal center line of the columnar member 126b is parallel to a vertical center line of the right portion 16U, 16L ', 16U "of the respective openings 16A, 16B, 16C (Figure 8). The oscillatory wing is rotatably positioned in front of the openings, moving towards the left portion of the openings, ie the longitudinal centerline of the columnar member 126b becomes parallel with a vertical centerline of the left portion 16L, 16U ' 16L "of the respective openings 16A, 16B, 16C (Figure 8). First, the compressor 11 and the evaporator 12 are operated in Figure 4, and the cold air is generated by the heat exchanger with the circumference of the evaporator 12. The cold air moves towards the freezer 2 and the cooling compartment 3 by means of fan 3 along the arrow. Depending on the temperature of the cooling compartment 3, the closing / opening operation of the display plate 19 is controlled (Figure 7). When the display plate 19 is opened, the cold air from the evaporator 12 is fed to the air passage 18 as shown in Figure 8, and the air is divided into the right and left side of the upper portion of the apparatus. of air distribution 17. A part of the cold air is discharged into the third compartment 9 through the air discharge opening 23 (Figure 5), while most of the cold air is discharged to the refrigerator 3 and the compartment of vegetables 10, after flowing along the first and second conduits 35 and 36. In Figure 8, the air along the conduits 35, 36 is guided by the respective branch conduits 37, 38, to be discharged to through the openings 16 in sequence from the top to the bottom. In addition, air through the openings is distributed in the direction of the right or left side by rotation of the oscillating wing 126 to generate uniform cooling of the cooling compartment. In the modality, the oscillating wing 126 is operated by a gear motor at a constant speed. The gear motor can also be replaced by a stepping motor, which has a variable rotating speed, if desired. However, in the specified area, if too many food products are placed, or if a relatively hot food is placed, the steady state of uniform cooling is altered, to create a difficulty of uniform cooling in a refrigeration compartment. To solve the problem, it is necessary to use concentrated cooling in the specified area. Figures 10A, 10B, and 10C, show the condition of the concentrated cooling of the left, central, and right side, respectively. Concentrated cooling can be achieved by directing the air flow to a predetermined direction under the command of the control system, as well as in the three directions mentioned above. To determine the direction of the concentrated cooling, or the discharge direction of the cold air, a right space temperature sensor or first temperature sensor 52 is installed in the upper center portion of the right wall of the cooling compartment 3, and is installed a temperature sensor of the left space or second temperature sensor 53 in the lower central portion of the left wall of the cooling compartment 3, as shown in Figure 5. The temperature sensors 52, 53, as well as the position switch 32 (Figure 6), are connected to a control member (not shown) by a conventional method. In addition, the motor 28 for rotating the oscillating wing 126 is connected to the control member. These components can detect the temperature variation in the cooling compartment to achieve effective concentrated cooling. Figure 11 illustrates the operation state of the position detecting switch 32, which determines the reference position of the oscillatory flange 126, and the protrusion "133" which is rotated in contact against the position switch 32. The protrusion 133 rotates in the direction of the arrow together with the oscillating wing 26, to be operated as shown in Figures HA, 11B, 11C.

Figure 11C shows the moment in which the electrical point of the position detection switch 32 is released, which considers the reference position of the oscillating wing in the mode. The protrusion of the contact portion with the position detection switch is configured O in a gently rounded manner to prevent any noise generated by the sudden release of the switch. The degree of rotation of the oscillating wing 126 is controlled by the control member, and the position detection switch 32 which is "turned on / off" 5 by the protrusion 133 of the oscillating wing 126. In the embodiment, the time when the protrusion 133 is released in a contracted manner from position detection switch 32, is set as the reference time (Figure 11C). The period of rotation of the oscillatory wing 0 is verified by a control member, thereby producing the degree of rotation. For example, assuming that the speed and rotation of the oscillating wing 126 is 6 rpm, the oscillating wing 126 rotates for 10 seconds from the reference point, thereby rotating a 5 turn.

- ^ Next, when a concentrated cooling is required for the left side, the oscillating wing 126 is temporarily fixed towards the left direction, in such a way that most of the cold air flow is directed towards the left side, as shown in FIG. shown in Figure 10A. In addition, when a concentrated cooling to the central area is required, the oscillating wing 126 is temporarily fixed in the central direction, such that the greater part of the cold air flow is directed towards the central area β, as shown in FIG. Figure 10B. In addition, when a concentrated cooling is required for the right side, the oscillating wing 126 is temporarily fixed in the right direction, such that most of the cold air flow is directed to the right side, as shown in FIG. Figure 10C. In the following descriptions of the different modalities of the oscillating wing, the same numerals and letters are used for the elements that work the same as those of the first modality, and an additional description 0 is omitted for the elements. Figure 12 shows a modified example of the first embodiment. The oscillating wing 126 'comprises a columnar member 126b extended upwards and downwards, and a distribution wing 147' which is placed on the columnar member 126b in an eccentric manner, and is formed as an oval in a cross section. It is more desirable that a pair of oscillating wings 126 'be installed on the front of the openings 16A, 16B, 16C, as described in the first embodiment. Figure 13 shows a second embodiment of the oscillating wings 226R, 226L. Each oscillating wing 226R, 226L comprises a plurality of wing members 241A, 241B, and 241C, and a columnar member 126b, respectively.

In this example, since the right portion 16U of the OR opening 16A of the air distribution apparatus 17 (FIG. 8) is placed out of phase with respect to the left portion 16L of it, a pair of oscillating wings can be used to achieve an effective air discharge. That is, one of the oscillating wings 226R is rotatably placed on the front of the right portion 16U, 16L ', and 16U ", of the openings 16A, 16B, and 16C, while the other of the oscillating wings 226L is placed rotatingly on the front of the left portion 16L, 16U ', and 16L "of the openings 16A, 16B, and 16C. The wing member 241A comprises a divider member 244A provided with a rounded plate, and a dispenser wing 247 provided perpendicularly on the divider member 244A. Each divider member 244A, 244B, 244C is positioned at each lower edge of the opening, ie, the divider member 244A 5 of the right swing wing 226R is at the lower edge - "- of the right portion 16U of the aperture 16A, while that the divider member 244A of the left swing wing 226L is at the lower edge of the left portion 16L of the aperture 16A.The diameter of the splitter members respective 244A, 244B, and 244C, is approximately equal to the width of the right or left portion of the respective openings 16A, 16B, and 16C. In the right swing wing 226R, the distribution wing 247 is provided with a concave part 250 and j.0 a convex part 251 which are rounded in series, respectively. That is, the concave part 250 and the convex part 251 are smoothly connected to form in an "S" configuration. The height of the distribution wing 247 is the same as the height of the respective right or left portions of the respective openings. By using the configuration of the distribution member on the splitter member, cold air is prevented from escaping. Next, the distribution wing 247 of the left oscillating wing 0 226 L has a different position with respect to that of the right oscillating wing 226 R. In the right swing wing 226R, the concave part 250 is placed in the same direction with respect to that of the protrusion 133 of the columnar member 126b, while the convex part 251 is placed in the opposite direction with respect to the "" the protrusion 133 of the columnar member 126b. In the left oscillating wing 226L, the convex part 251 is placed in the same direction with respect to that of the protrusion 133 of the columnar member 126b, while the concave part 250 is placed in the opposite direction with respect to that of the protrusion 133 of the columnar member 126b. The placement of the distribution wing 247 is to reduce the flow resistance, which corresponds to the placement of the right and left portions 16U, 16L of the opening 16A. The air guided by the distribution wing 247 impacts on the convex part 251 to a large extent, and flows on the convex part 251, thereby significantly reducing the flow resistance. The cold air generated from the evaporator 12, 5 as shown in Figure 8, is discharged for the most part towards the refrigeration compartment 3 and the vegetable compartment 10, after flowing along the first conduit 35 and the second one. conduit 36. Accordingly, the air guided through the first conduit or branch 37A on the right side is flowed in a striking manner over the convex part 251 of the right distribution flange 226R, while the air guided through the second conduit branch 38A on the left side is flowed in an impacted manner on the convex part 5 of the left distribution wing 226L, which - "" develops a main flow. Furthermore, the horizontal plate-shaped dividing member keeps the weak air discharged in approximately one horizontal direction towards the cooling compartment, even when the oscillating wing is in the slow rotation mode. When concentrated cooling is required for the specified area of the refrigeration compartment, the concentrated cooling, as shown in Figures 10A, 10B, 10C, is achieved by using the protrusion 133 provided at the upper end of the columnar member 126b. Figure 14 shows a modified example of the second embodiment. The oscillating wing has the same components as the second embodiment of Figure 13. Additionally, the oscillating wing comprises a plurality of slots 245 formed on the circumference of the respective partition members 241A, 241B, 241C along the extended direction of the member. columnar 126b. Slots 245 are for cold air that is not discharged at 0 through grid 27 yet (Figure 7). The air remaining above the divider member 241A actively flows down through the slots 245, as well as through the gap G between the rear surface of the rack 27 and the circumference of the swinging wings 226R ', 226L'. Figures 15A, 15B illustrate a third < "" modality of the oscillating wing 326. The oscillating wing 326 comprises a plurality of wing members 326a and a columnar member 326b. The wing member 326a comprises a divider plate 344 having an upper plate 341, a middle plate 342, and a lower plate 343, which are separated from one another in a horizontal manner. The wing member 326a further comprises a distribution wing 347 which provides a first inductor flange 345 formed perpendicularly between the upper plate 341 and the plate -0 medium 342, and a second inductor wing 346 formed perpendicularly between the middle plate 342 and the lower plate 343. In the embodiment, three assemblies 361, 362, 363 of the wing member 326a formed with the partition plate 344 are integrally assembled and the distribution wing 5 347, with the columnar member 326b (the remaining 349 will be explained later). That is, the oscillating wing 326 is formed in such a way that the three wing members 326a, which have the divider plate 344 and the distribution wing 347, are integrally coupled to the columnar member 326b. The upper end 0 of the oscillating wing 326 is connected with an output shaft (Figure 6) of the impulse motor 28, to operate the oscillating wing 326. It is more desirable that the columnar member 326b be configured with a cross in a cross section. The numeral 349, in Figures 15A and 15B, is a "~ phantom wing assembly (false) that is irrelevant to the discharge of cold air, since no opening is provided in the position corresponding to the ghost wing. (false) 349, is not directly related to the flow air discharge. However, through gap G (Figure 7) between the rear surface of the grid 27 and the circumference of the oscillatory wing 26, the cold air is fed into the space that houses the ghost wing (false) 349. The air in that space is agitated by the phantom (false) wing 349, to increase the distribution effect with respect to the air flowing down to the lower wing member 363. In addition, the configuration Balance of the wing member provides an external harmony. The oscillating wing 326 is formed in a detachable manner as shown in Figure 15B, to solve the problem arising from the manufacturing process. The upper portion of the oscillating wing 326 consists of the upper wing member 361 and the middle wing member 362, 0 and the lower portion of the swing wing 326 consists of the lower wing member 363. In the case that the wings of distribution 347 are molded in a different direction from each other (as will be explained in more detail below), there is the difficulty that a cavity mold shape can not be used. Consequently, the oscillating wing 326 is divided into two portions. In the upper portions 361, 362 of the oscillatory flange 326, the edges 347E, 347E 'of the distribution wings 345, 346 are formed at 90 ° with each other. At the lower portion 349, 363 of the oscillatory flange 326, the edges 347E ", 347E" 'of the distribution flange 345, 346, are configured at 0 ° or 180 ° with each other. Accordingly, if the degree of assembly between the upper portions 361, 362, and the lower portions 349, 363 is / "- 0 can change, you can vary the deployment of all the distribution 345, 346. In the mode, the edges 347E", 347E "'are placed in the center between the bank 347E and the bank 347E' Figure 15C shows a modified example of the third modality, which illustrates the oscillatory wing 326 without the (false) phantom wing assembly 349. As illustrated above, the respective distribution wings 347 are positioned opposite the corresponding openings 16 (Figure 8), and the position of the partition plate 344 and the openings 16 correspond to the space divided between the shelves 8 of the refrigeration compartment 3. The oscillatory wing 326 is placed in front of the front plate 24, as shown in Figure 6. The middle plate 342 of divider plate 344 is placed on the border between the right portion 16U and the "" '* left portion 16L (Figure 8). The upper plate 341 is placed above the middle plate 342, with the height of the right portion 16U, while the lower plate 343 is placed below the middle plate 342 with the height of the left portion 16L. The upper, middle and lower plates 341, 342, and 343, have the same diameter. The diameter is approximately equal to the horizontal width of the opening 16, to prevent the cold air from escaping. The space defined by the upper plate 341, the middle plate O 342, and the right portion 16U, forms a single rotation passage with the aid of the conduit extended from the branch conduit 37A. Also, the space defined by the middle plate 342, the lower plate 343, and the left portion 16L, form another individual rotation passage with the support of the conduit extended from the branch conduit 38A. The individual rotation passages help the discharge of air into the cooling compartment without descending. It keeps the weak air discharged in an approximately horizontal direction towards the cooling compartment, even when the oscillating wing is in the slow rotation mode. In addition, the first distribution wing 345 and the second distribution wing 346 are placed with a symmetrical arrow. In more detail, the inductor wings 345, 346 5 are provided with a concave part 350 and a part <; * "convex 351 which are rounded in series, respectively, i.e., the concave part 350 and the convex part 351 are smoothly connected to form in an" S "configuration.As a result, air is gently discharged throughout Next, the first inductor flange 345 has a different position with respect to the second inductor flange 346. The concave portion 350 of the first inductor flange 345 is placed on the first and second inductor wings 345, 346 through the opening 16. 0 inversely to the convex part 351 of the second inductor wing 346, while the convex portion 351 of the first inductor flange 345 is positioned inversely to the concave portion 350 of the second inductor flange 346. The placement of the inductor wings 345, 346 is to reduce the flow resistance, which corresponds to the placement of the right and left portions 16U, 16 L. The air guided by the inductor wings 345, 346 impacts on the convex part 351 to a large extent, and it flows on the convex part 351, thereby significantly reducing the resistance 0 to the flow. The convex portion 351 of the first distribution wing 345 is positioned towards the slightly right side of the opening 16A. In an alternative way, the convex portion 351 of the second distribution wing 346 is positioned towards the slightly left side of the opening 16A. Accordingly, air guided through the first - • * "" branch conduit 37A on the right side is flowed in an impacted manner over the convex part 51 of the first inductor wing 345, while the air guided through the second branch conduit 38A on the left side, 5 is flowed in an impacted manner on the convex part 51 of the second distribution wing 346, which develops the main flow. In a similar way to the aforementioned modalities, in this modality it is also needs a concentrated cold air flow. Assuming that the edge 347E of the upper wing member 361 is the base, the edge 347E 'of the middle wing member 362 is positioned at approximately 90 °, and the edge 347E "' of the lower wing member 363 is positioned at approximately 45 °. As the 5 upper, middle, and lower distribution wings 361, 362, 363 are configured in a different directional direction with each other, the point of impact and the discharge direction on / from the distribution flange 347 of the cold air is variable, thereby causing the load 0 applied to the distribution wing 347 to decrease. If the edges 347E, 347E ', 347E ", 347"' of the inductor wings 345, 346 are aligned, the cold air discharged from the different rotation position, impacts on the distribution wing in the same direction, and causes an excessive load on the oscillating wing 5. In the modality, the - / ~ degrees of the configuration of the distribution wing assemblies are different from each other. others, and not pu When the problem of an excessive burden arises. The banks 347E, 347E ', 347E "' are placed inside of about 90 °, regardless of the rotational position of the oscillating wing 326. At the same time, the other edges are placed within approximately 90 ° on the opposite side. By using different angled edges, chilled air discharged through the openings is blown in a concentrated manner within approximately 90 ° to the specified area, ie the area on the left, center, and right side of the compartment of refrigeration, as illustrated in Figures 10A, 10B, 10C, respectively. The operation of the concentrated cooled air flow is performed using the protrusion 133 provided at the upper end of the columnar member 126b, as the operation of Figures HA, 11B, 11C. In this embodiment, a single oscillating wing 326 is employed, since the configuration feature of the oscillating wing 326 is coupled with the nature of the air flow through the openings of the air distribution apparatus 17. FIGS. 21 illustrate different? f * ~ embodiments of a cold air distribution apparatus, without an air guide element, which adopts the above modalities. Figure 16 shows the rear perspective view of another air distribution apparatus without the air guide element, which comprises the air passage 15, the openings 16, and the related components. Except for the air guide element, all the components of Figure 16 are identical to those of Figure 8. The same component parts of Figure 16 * 0 are designated by the same reference numerals as in Figure 8, but the detailed description of the parts will be omitted. Figure 17 shows a fourth embodiment of the oscillatory wing 426R, 426L. Each oscillating wing 426R, 426L comprises a wing member 427 and a columnar member 126b, respectively. The wing member 427 is formed as a ^ plate extending in a vertical direction, and has a plurality of partition members 444A, 444B, 444C, which are likewise separated from one another in a manner horizontal, and are formed perpendicularly on a vertical lateral surface of the wing member 427. In this example, although the dividing members are provided only on a vertical lateral surface of the wing member 427, both vertical side surfaces may Provide a plurality of dividing members. The position of the respective splitting members 444A, 444B, 444C, corresponds to the respective lower edges of a plurality of openings coupled (not shown) of the grid 27. In addition, the respective openings of the grid 5 27 are coupled with the space divided between the shelves 8 of the cooling compartment 3. Accordingly, the air flow down through the conduits 35A, 36A is guided to the respective divided spaces of the refrigeration compartment 3.! 0 The cold air generated from the evaporator 12, as shown in Figure 16, is discharged for the most part towards the refrigeration compartment 3 and the storage compartment. vegetables 10, after flowing along the first conduit 35A and the second conduit 36A. Consequently, the air guided through the first conduit 35A on the right side is directed as it hits the respective dividing members 444A, 444B, 444C in sequence, while the air guided through the second conduit 36A on the left side is directed. direct on impacting or on the respective dividing members 444A, 444B, 444C in sequence. In addition, the horizontal plate-shaped dividing members 444A, 444B, 444C keep the air impacted by rotating in a direction of approximately 90 ° towards the cooling compartment. 5 When a concentrated cooling - "~" is required for the specified area of the refrigeration compartment, the concentrated cooling, as shown in Figures 10A, 10B, 10C, is achieved by using the protrusion 133 provided at the end upper of the columnar member 126b. Figure 18 shows a modified example of the fourth embodiment. The oscillating wing has the same components as the fourth embodiment of Figure 17. The oscillating wing 426 'comprises a columnar member 126b IO extended vertically, and a wing member 447 'which is placed on the columnar member 126b. It is more desirable that a pair of oscillating wings 426 'be installed in the first conduit 35A and in the second conduit 36A described in the fourth embodiment. In an alternative way, a plurality of distribution wings 444D, 444E, 444F, are tilted downward and outward. Figure 19 illustrates a fifth embodiment of the oscillating wing 526. The oscillating wing 526 comprises a wing member 547 and a columnar member 126b. The member of wing 547 is formed as a helix-shaped plate that extends in a vertical manner. In addition, the wing member 547 is integrally assembled with the columnar member 126b. In addition, the protrusion 133 is provided at the upper end of the oscillating wing 526, to control the The rotational position of the oscillating wing 526 when a flow is located in the cooling compartment 3. It is more desirable that a pair of oscillatory wings 526 be installed in the first conduit 35A and in the second conduit 36A, described in FIG. The fourth embodiment The propeller 5 angle of the wing member 547 is more inclined at the inlet portion or higher than at the outlet portion or lower.The volume of air impacted on the lower portion of the wing member 547 is greater On top of this, it satisfies the need that the lower the air goes, the more air is needed. The cold air generated from the evaporator 12, as shown in Figure 16, is mostly discharged to the cooling compartment 3 and the vegetable compartment 10, after flowing along the first conduit 35A and the second conduit 36A.Therefore, the air guided through the first and second or ducts 35A, 36A on the right or left side, impact on the upper portion of the wing member 547. The part of the impacted air is discharged into the space 0 divided between the shelves 8 of the cooling compartment 3, through the opening corresponding top of the grid 27. Through the middle opening of the grid, a greater volume of air flows than from the upper opening, into the corresponding space. At 5 the lowest opening of the grid, a larger volume of air is discharged than at the medium opening, into the refrigerator space 3. When a concentrated cooling is required for the specified area of the refrigeration compartment, concentrated cooling, as shown in Figures 10A, 10B, 10C, is achieved by using the protrusion 133 provided at the upper end of the columnar member 126b. Figure 20 shows a modified example of the fifth embodiment. The oscillating wing has the same components as the fifth embodiment of Figure 19. The oscillating wing 526 'comprises a columnar member 126b vertically extended, and a wing member 547' which is placed in the columnar member 126b. In an alternative way, the configuration of the wing member 547 'has an angular helix. Figure 21 illustrates a sixth embodiment of the oscillating wing 626. The oscillating wing 626 comprises a hollow cylindrical member 626b and a columnar member 126b projecting upwards or downwards from both upper and lower ends of the cylindrical member 626b, around which it is made rotate the cylindrical member 626b. The protrusion 133 is provided at the upper end of the upper columnar member 126b, to control the rotational position of the oscillating wing 626, when a localized flow is required in the cooling compartment 3. It is more desirable that a pair of oscillating wings be installed. 626 in the first conduit 35A and in the second conduit 36A described in the fourth embodiment. further, a propeller wing member 647 is formed on the inner wall of the cylindrical member 626b. A side edge 647a of the propeller member 647 slopes downward, and is formed in contact along the internal wall of the cylindrical member 626b. Another side edge 647b of the propeller member 647 is inclined and extends almost perpendicularly to the center of rotation of the cylindrical member 626b. On the wall of the cylindrical member 626b, there are a plurality of openings 66A, 66B, 66C that are separated from each other in a horizontal manner. The position of the respective openings 66A, 66B, 66C corresponds to the space divided between the shelves 8 of the cooling compartment 3. At the same cross-sectional point of the inclination of the propeller member 647, a lateral end edge 647a of the propeller member 647, while the other side end edge 647b thereof, is tilted upwards. The upward inclined angle of the inner edge 647b with respect to the outer edge 647a, is the lowest in the upper opening 66A, while it is the highest in the lower opening 66C. Accordingly, the angle inclined upwards is half of the middle opening 66B. Due to the configuration of the inclination, the least amount of air is discharged through the upper opening 66A, and the largest quantity of air is discharged through the lower opening 66C. The cold air generated from the evaporator 12, as shown in Figure 16, is mostly discharged to the refrigeration compartment 3 and the vegetable compartment 10, after flowing along the first conduit 35A and the second conduit 36A. Accordingly, the air guided through the first and second conduits 35A, 36A on the right or left side is flowed in an impacted manner over the inclination of the propeller member 647 adjacent the upper opening 66A. Part of the impacted air is discharged into the space divided between the shelves 8 of the refrigeration compartment 3, through the corresponding upper opening 66A of the edge 27. Through the middle opening 66B, a greater volume of air flows through the medium. from the upper opening, towards the corresponding space. At the lower opening 66C, a larger volume of air is discharged than at medium opening 66B, into the refrigerator space 3. When a concentrated cooling is required for the specified area of the refrigeration compartment, the concentrated cooling, as shown in Figures 10A, 10B, 10C, it is achieved by using the protrusion 133 provided at the upper end of the columnar member 126b. As described in detail above, uniform cooling can be performed more effectively by means of different oscillatory wing patterns that disperse the cold air discharged. In the event that there is any temperature deviation in the compartment, the area with a relatively high temperature may receive the concentrated cooling for some period, until the uniform temperature is reached. In accordance with the above, the present invention has the advantage of achieving a concentrated cooling in any case.
