Further, the first and second fans may be configured to direct cool air generated by the first and second evaporators to the freezing and refrigerating chambers, respectively. Additionally, a plurality of cool-air ducts may be provided in at least one of the freezing and refrigerating chambers; the cool air ducts may be configured to provide cool air to the freezing and refrigerating chambers via operation of the first and second fans, respectively.

[0005] The invention provides an additional improvement, an additional advantage or an alternative to the prior art.SUMMARY OF THE INVENTION

[0006] The object of the invention is to provide a cooling device, particularly a household cooling device having at least one air distribution opening in a cooling part of the cooling device, where an aesthetical appearance shall be provided to users of the cooling device and where temperature difference in the cooling part shall be minimized and which can be easily produced and which provides cost advantage.

[0007] Another object of the subject matter invention is to provide decrease of the temperature degree difference, that exists in the cooling part existing in the cooling device, to preferably lower than 1 centigrade degree.

[0008] In order to achieve the object, the subject matter cooling device contains a cooling part, an inner rear wall that exists in the cooling part, at least one air distribution opening provided at the inner rear wall, at least one air channel through which the cold air passes and which is suitable for being connected to the other side of the inner rear wall which does not face the cooling part in a manner covering the air distribution opening, at least one air passage gap configured to correspond to the air distribution opening at the air channel, at least one air transfer part which is suitable for being connected to the air channel and which provides transfer of the cold air, formed by at least one evaporator by means of at least one fan, to the air channel, at least one air feeding opening positioned at the inner rear wall and adapted for passing the air, which exists in the cooling part, to at least one evaporator air input part which exists in the evaporator, by means of at least one air feeding channel, and at least one air channel surface extension which can exist at an air channel front surface in order to allow passage of different amounts of air, by at least two air distribution openings which are equivalent to each other, from the air channel to the cooling part. By means of this, while the air distribution openings are seen by the users in a manner having exactly the same size, namely equivalent to each other on the cooling part inner rear wall, the air distribution openings can be configured to be able to provide different amounts of cold air passage from the air channel to the cooling part. This condition will contribute to enhancing of the aesthetical appearance of the inner rear wall that exists in the cooling part. Additionally, input of different amounts of cold air to the cooling part through different air distribution openings which have the same size as each other is possible, the temperature differences which may occur in the cooling part will be prevented. In other words, temperature balance in the cooling part can be provided.

[0009] Here, by means of the “cooling device”, it is desired to describe any device, particularly a household cooling device, a refrigerator used in houses and which can realize cooling function and which has a cooling cycle.

[0010] Here, by means of “the other side of the inner rear wall which does not face the cooling part”, it is desired to describe the other side of the inner rear wall which is not seen by a user who looks in a manner seeing the inner rear wall that exists in the cooling part. In other words, it is desired to describe the rear side of the inner rear wall.

[0011] Here, by means of the “at least two air distribution openings which are equivalent to each other”, it is desired to describe that the air distribution openings are the same as each other in a width direction, in a depth direction and in a height direction.

[0012] Here, by means of the “air transfer part”, it is desired to describe a part which can also be mentioned as a fan housing and where a pressure chamber exists.

[0013] In a possible embodiment of the invention, the cooling device contain at least one air distribution opening positioned to the inner rear wall in a manner corresponding to the lower side of an inner upper wall that exists in the cooling part. By means of this, cold air input through the lower side of the inner upper wall of the cooling device from the air channel to the cooling part can be possible. Thus, by preventing the fluctuations in the temperature degree of the lower side of the inner upper wall of the cooling part, contribution is made for prevention of the temperature differences which may occur in the cooling part.

[0014] Since the air distribution opening is positioned at the lower side of the inner upper wall preferably in a manner close to the inner upper wall, the cold air, which comes from the air channel and which enters the cooling part through the air distribution opening, is prevented from meeting with any obstacle. Thus, blocking of cold air input through the air distribution opening from the air channel to the cooling part is prevented.

[0015] Here, the mentioned inner upper wall can also be mentioned as a ceiling of the cooling part.

[0016] Here, the mentioned inner rear wall can also be mentioned as a rear side of the cooling part.

[0017] In a possible embodiment of the invention, the cooling device contains at least one air distribution opening placed to the cooling part in a removable manner and positioned to the inner rear wall in a manner corresponding to the lower side of a plate-like separation unit which is suitable for providing formation of a cooling compartment. By means of this, air is input from the air channel to the cooling part through the lower side of the plate-like separation unit. Thus, fluctuations in temperature degree which may occur in the cooling compartment which occurs by placement of plate-like separation unit to the cooling part are prevented, and contribution is made for the prevention of temperature differences which may occur in the cooling part.

[0018] Since the air distribution opening is positioned at the lower side of the inner upper wall preferably in a manner being close to the inner upper wall, the cold air, which comes through the air channel and which enters the cooling part through the air distribution opening, is prevented from meeting with any material placed to the cooling compartment for being cooled. Thus, blocking of cold air input from the air channel to the cooling part through the air distribution opening is prevented.

[0019] In the preferred usage, the plate-like separation unit can be a shelf produced from glass material. However, if preferred, it is also possible that the plate-like separation unit can be produced from a different material.

[0020] In a possible embodiment of the invention, the cooling device contains air passage gap and air distribution opening which have the same size as each other and which are suitable for providing cold air passage from the air channel to the cooling part. By means of this, the cold air which comes from the air channel can enter the cooling part without meeting with any obstacle, namely without delimiting cold air passage. Here, by means of the statements of the air passage gap and the air distribution opening which have the same size as each other, it is desired to describe that the air passage gap and the air distribution opening have the same sizes in width and height direction.

[0021] In a possible embodiment of the invention, the cooling device contains an air passage gap configured to be bigger than the air distribution opening, which is suitable for providing cold air passage from the air channel to the cooling part, in the height direction z. By means of this, it can be possible that the size of the air passage gap, that exists in the air channel, in the height direction, is bigger than the size of the air distribution opening in the height direction. In other words, since the air passage gap is bigger than the air distribution opening, the amount of cold air which comes from the air passage gap to the air distribution opening can be increased.

[0022] In a possible embodiment of the invention, the cooling device contains an air channel surface extension which is suitable for connecting to the air channel front surface, which exists in the air channel, in a manner partially closing the air passage gap in the height direction z and which provides that the air passage gap is smaller than the air distribution opening in a manner providing partial cold air passage from the air channel to the cooling part. By means of this, since the cold air, which comes from the air channel, meets with the air channel surface extension, namely with an obstacle, the input of the cold air to the cooling part from the air distribution opening is delimited. The air passage gap is partially closed in the height direction by means of the air channel surface extension. Since the air channel surface extension can be connected to the air channel front surface, the air passage gap can be closed at the desired proportion. It can be possible that the air channel surface extension can be connected to the air channel front surface, on or under the air passage gap or both on and under the air passage gap in the height direction. This facilitates the closing of the air passage gap in the height direction with the preferred dimension at the air channel front surface. By means of this, the air passage gap can be smaller than the air distribution opening. In other words, by blocking the cold air, which comes from the air channel, by means of the air channel surface extension, the cold air can partially enter the cooling part.

[0023] In a possible embodiment of the invention, the cooling device contains an air channel surface extension which is suitable for being produced one-piece with the air channel front surface in a manner partially closing the air passage gap in the height direction z and which provides that the air passage gap is smaller than the air distribution opening in a manner providing partial cold air passage from the air channel to the cooling part. By means of this, since the cold air, which comes from the air channel, meets with the air channel surface extension, namely with an obstacle, the input of cold air to the cooling part from the air distribution opening is delimited. The air passage gap is partially closed in the height direction by means of the air channel surface extension. The air channel surface extension can be produced in a one-piece manner with the air channel front surface. Thus, production of the air channel which has air passage gap with desired size can be possible. This provides advantages in terms of cost. Moreover, by providing an air passage gap that is smaller than the air distribution opening, the cold air, which comes through the air channel, can partially enter the cooling part.

[0024] Here, by the inscription “partially”, it is desired to describe that a part of the air passage gap is closed in the height direction. By means of this, it is desired to mention that a partial cold air passage from the air passage gap to the cooling part is possible.

[0025] In a possible embodiment of the invention, the cooling device contains at least two air channels, which are suitable for being placed to the other side of the inner rear wall, which does not face the cooling part, in an orthogonal manner to the inner upper wall such that the air channels cover the air distribution openings and are parallel to each other such that there is a distance in between in the width direction x. By means of this, the temperature degree differences which may occur in the cooling part are prevented. The number of air channels which make contribution to the cooling part in accordance with the size of the cooling device can be increased. By means of this, the cooling part is cooled more rapidly. In the preferred usage, the air channels are positioned to the other side of the inner rear wall which does not face the cooling part in an orthogonal manner to the inner upper wall and in a parallel manner to each other such that there is a distance in between in the width direction x. Additionally, the air channels can be positioned in a manner parallel to a first side wall and a second side wall forming the cooling part and such that there remains a distance in the width direction between the first side wall and the second side wall. In the preferred usage, the air channel can be in the form of rectangular prism, however, it can also be possible that the air channel has a different shape. In the preferred usage, the air channel, which is in the form of a rectangular prism, has been separated into two equal compartments by means of the support part. In other words, the air channel is separated into a first compartment and a second compartment. In another preferred application of the invention, when the mentioned first compartment, the second compartment and the support part between the first compartment and the second compartment and the air distribution grid are removed, the cooling part can be seen at the inner rear wall. Here, the distance can be described as the distance in width direction, which can exist between the first side wall and the second side wall of the cooling part and the air channel or between at least two air channels in accordance with the size of the cooling device, in other words, in accordance with the width of the cooling device.

[0026] In a possible embodiment of the invention, the cooling device contains at least two air distribution openings positioned in a manner corresponding to the lower side of the inner upper wall and in a parallel manner to the inner upper wall, where each of the at least two air distribution openings is positioned to the inner rear wall in a manner corresponding to at least one air channel. By means of this, the temperature degree differences that may occur in the cooling part are prevented.

[0027] In a possible embodiment of the invention, the cooling device contains at least two air distribution openings placed to the cooling part in a removable manner and positioned to the inner rear wall in a manner corresponding to the air channel, in a parallel manner to a plate-like separation unit and in a manner corresponding to the lower side of the plate-like separation unit which is suitable for providing formation of the cooling compartment. By means of this, the temperature degree differences which may occur in the cooling part are prevented. In the preferred usage, the air distribution openings are positioned in a manner corresponding to the air channels. In accordance with the size of the cooling device, in other words, in accordance with the width of the cooling device, the number of air channels can be increased, thus, the number of air distribution openings that correspond to the air channel can also be increased.

[0028] In a possible embodiment of the invention, the cooling device includes an air channel formed by a single compartment that is suitable for transfer of cold air. By means of this, the cold air, which comes from the air channel, is transferred to the air passage gap without being interrupted, in other words, such that the cold air flow is not prevented.

[0029] In a possible embodiment of the invention, the cooling device includes at least one support part which provides separation of the air channel into at least two compartments and configured between an air channel front surface and an air channel rear surface in a manner preventing deterioration of the form of the air channel and in a manner orthogonal to the air channel front surface and the air channel rear surface. By means of this, deterioration of the form of the air channel is prevented. Thus, narrowing of the cross-section of the air channel, through which cold air comes, is prevented. This increases the usage lifetime and efficiency of the air channel. There can be more than one support part. Thus, if preferred, the air channel can be separated into more than two compartments. Moreover, the air channel front surface and said air channel rear surface can be parallel to each other.

[0030] In a possible embodiment of the invention, the cooling device contains at least one air distribution grid which connects to the air distribution opening and which provides distribution of the cold air, which passes to the cooling part through the air channel, to the cooling part. By means of this, the cold air which comes from the air channel and which passes through the air passage gap and air distribution opening can be easily distributed to the cooling part. By means of this, the temperature degree difference inside the cooling device can be decreased.

[0031] In a possible embodiment of the invention, in the cooling device, the air distribution grid contains at least one inclined guiding part which provides the cold air, which comes from the air channel, to be distributed to the cooling part. By means of this, the cold air which comes from the air channel and which passes through the air passage gap and the air distribution opening can be easily distributed to the cooling part. In other words, cold air can be transferred also towards the first side walls and the second side wall of the cooling part. By means of this, the temperature degree difference inside the cooling device can be decreased.

[0032] In a possible embodiment of the invention, in the cooling device, the air distribution grid comprises at least one flat guiding part which provides the cold air, which comes from the air channel, to be distributed to the cooling part. By means of this, the cold air which comes from the air channel and which passes through the air passage gap and the air distribution opening can be easily distributed to the cooling part. By means of this, the temperature degree difference inside the cooling device can be decreased. In the preferred usage, the flat guiding part which exists in the air distribution grid is positioned in a manner corresponding to the support part.

[0033] In a possible embodiment of the invention, the cooling device is in rectangular form configured such that the air distribution openings, which exist at the inner rear wall in the cooling part, are at the same size as each other in the width direction x and in the height direction z. By means of this, the user, who looks at the air distribution openings from the cooling part side, can see that the air distribution openings positioned at the inner rear wall are at the same size. This provides contribution for enhancing the aesthetic appearance of the cooling part. The user satisfaction increases in this direction. Even though the air distribution opening is preferably in rectangular shape, it can be arranged in any shape. By means of this, the cross-section of the air distribution opening is increased. Moreover, by means of the rectangular shape of the air distribution opening, the friction surface is reduced, and contribution is made in the direction of not reducing the pressure of cold air which comes from the air channel.

[0034] In a possible embodiment of the invention, the cooling device contains at least one connection element which provides connection of the air distribution grid to the air distribution opening. By means of this, the air distribution grid can be snap-fixed to the air distribution opening. In the preferred usage, the air distribution grid can be connected to the air distribution opening by means of at least one connection element. Preferably the connection element can be a connection tab. However, if preferred, different connection elements like adhesive, screw can also be used. The mentioned connection tab can be positioned on a first part or on a second part or can be positioned both on the first part and on the second part of the air distribution grid. In the preferred usage, on both the first part and the second part, at least one connection tab is formed in a one-piece manner with the air distribution grid. In the preferred application of the invention, there are totally four connection tabs in the air distribution grid. In order to create connection tab form both in the first part and the second part, a forming process, in other words a cutting process can be realized in a manner forming connection a tab in the first part and in the second part. This prevents extra material usage for the connection tab, thus, this provides prevention of occurrence of extra cost. In an application of the invention, the air distribution grid is connected to the air distribution opening which exists at the inner rear wall in the cooling part. In this stage, the holding surface which exists in the air distribution grid prevents sliding of the air distribution grid from the inner rear wall towards the air passage gap, and a more stable connection is provided. The air distribution grid is in the form of a channel which narrows from the inner rear wall towards the air passage gap. More specifically, the air distribution grid is seen in oblong form at the inner rear wall. However, by advancing the lateral parts towards the flat guiding part from the inner rear wall towards the air passage gap, a channel structure is formed which narrows from the oblong form, which exists in the inner rear wall, towards the air passage gap. However, the air distribution grid can be made also in different forms. Moreover, the air distribution grid also contributes to the aesthetic appearance in the cooling part. The air distribution grid can be produced from plastic material. By means of this, it can be possible that the desired shape is given to the air distribution grid. In the preferred usage, the air distribution grid is used which is formed by two inclined guiding parts and one flat guiding part. The inclined guiding parts have inclined structure in a manner providing guidance of the cold air towards the first side walls and the second side walls of the cooling part.

[0035] In a possible embodiment of the invention, an insulation material can be connected along the air channel between the air channel and the other side of the inner rear wall which does not face the cooling part. The insulation material can be selected from EPS Expanded Polystyrene. By means of this, due to the temperature degree difference between the air in the cooling part and the cold air that passes through the air channel, the condensation which may occur at the parts which correspond to the air channels at the inner rear wall of the cooling part is prevented. In other words, formation of droplets at the sections which correspond to the air channels at the inner rear wall of the cooling part is prevented. By means of this, user satisfaction increases, and an aesthetic appearance is obtained in the cooling part. Moreover, also in the insulation material, there are openings at the parts which correspond to the air passage gap and the air distribution opening.

[0036] In a possible embodiment of the invention, the air channel can be connected to the other side of the inner rear wall, which does not face the cooling part, by means of the double-sided band. If preferred, instead of the double-sided band, connection can be provided between the air channel and the other side of the inner rear wall, which does not face the cooling part, by means of engagement connection.

[0037] In a possible embodiment of the invention, after the air channel is connected to the other side of the inner rear wall which does not face the cooling part, liquid polyurethane is added to the air channel rear surface side. When the liquid polyurethane solidifies, the air channel rear surface is completely covered. Access to the air channel through the air channel rear surface is not possible. By means of this, insulation can be provided between the cooling part, that exists in the cooling device, and an outer medium where the cooling device exists. Contribution is made for protection of the cooling function of the cooling part. At this point, the support part, that can exist in the air channel, prevents flexing of the air channel rear surface towards the air channel front surface as a result of adding polyurethane from the air channel rear surface side.

[0038] In a possible embodiment of the invention, in the cooling part, there can be at least one drawered part which enables storage of various materials. The drawered part can be positioned in a manner corresponding to the air transfer part and the evaporator in the cooling part. The air distribution openings are positioned between the drawered part and the inner upper wall. In the preferred usage, there are two air distribution openings which are parallel to the inner upper wall and which are in a manner corresponding to the lower side of the inner upper wall. At the same time, the air distribution openings are positioned in a manner corresponding also to the air passage gap that exists in the air channels. The air distribution opening and the air passage gap that exists in the air channel are at the same size as each other in the height and width direction. It can be also possible that the air passage gap, that exists in the air channel, is bigger than the air distribution opening in the height and width direction. Therefore, the air distribution openings, positioned in a manner corresponding to the lower side of the inner upper wall, is the part where maximum cold air input is realized into the cooling part. In the preferred application, the air passage gap, which corresponds to the air distribution openings which exist at the lower side of the inner upper wall, is nearly 10 mm in the height direction. Cold air is inclined to collapse due to its structure. By means of this, by collapsing of the cold air, which exists at the lower side of the inner upper wall, towards the drawered part, the temperature degree difference which may occur between the lower side of the inner upper wall and the other parts of the cooling part, is prevented. Therefore, in the preferred application, the air distribution openings, positioned in a manner corresponding to the lower side of the inner upper wall, are configured to provide maximum cold air input to the cooling part.

[0039] In a possible embodiment of the invention, there are two air distribution openings in a parallel manner to the plate-like separation unit at the lower side of the plate-like separation unit. In the preferred usage, there are two plate-like separation units in the cooling part. The plate-like separation unit can be positioned in a manner remaining in the region which exists between the drawered part and the inner upper wall in the cooling part. However, if preferred, it can be positioned at equal distance to the inner upper wall and the drawered part. The second plate-like separation unit can be positioned in a manner closer to the drawered part in the cooling part. Thus, there are totally four air distribution openings positioned at the lower side of the plate-like separation unit and the second plate-like separation unit in a manner parallel to the plate-like separation unit and the second plate-like separation unit and in a manner corresponding to the air passage gaps that exist in the air channels. In the preferred usage, the air passage gap, which exists on the air channel front surface which corresponds to the air distribution opening positioned at the lower side of the plate-like separation unit, is configured to be nearly 6 mm in the height direction. In the preferred usage, the air passage gap, which exists on the air channel front surface which corresponds to the air distribution opening positioned at the lower side of the second plate-like separation unit, is configured to be nearly 6 mm in the height direction. The configuration processes are possible by means of the air channel surface extension.

[0040] In a possible embodiment of the invention, cold air passage occurs with proportion of nearly 42% through the air passage gaps which are nearly 10 mm in the height direction corresponding to the air distribution openings positioned at the lower side of the inner upper wall. Cold air passage occurs with proportion of nearly 36% through the air passage gaps which are nearly 6 mm in the height direction corresponding to the air distribution openings positioned at the lower side of the plate-like separation unit. Cold air passage occurs with proportion of nearly 22% through the air passage gaps which are nearly 6 mm in the height direction corresponding to the air distribution openings positioned at the lower side of the second plate-like separation unit. Thus, the passage of the cold air, which comes from the air channel, to the cooling part is possible in a 100% manner. The total of the proportions can change provided that the total is 100% by increasing the plate-like separation units, thus, by increasing the air distribution openings positioned to the lower side of the plate-like separation units and by increasing the air passage gaps corresponding to said air distribution openings. Moreover, it is assumed that the dimension of the air passage gaps in the width direction is fixed. In the preferred usage, the dimension of the air passage gaps in the width direction can be nearly 80 mm.

[0041] In an application of the invention, there is an evaporator cover positioned at the inner rear wall in the cooling part in a manner closing the air transfer part and the evaporator which corresponds to the drawered part. In other words, the evaporator cover forms the part of the inner rear wall which corresponds to the drawered part. By means of this, if desired, the evaporator cover is removed from the cooling part, and access can be provided to the evaporator and to the air transfer part and thus to the fan. In the preferred usage, the mentioned air transfer part is formed by connecting at least one air transfer part front face and at least one air transfer part rear face to each other. By means of this, the air transfer part can also be mentioned as a fan housing and there can be a pressure chamber in the air transfer part. Moreover, the evaporator cover also provides an aesthetic appearance.

[0042] In a possible embodiment of the invention, there is at least one air feeding opening positioned at the inner rear wall and adapted for passing the air, which exists in the cooling part, to at least one evaporator air input part which exists in the evaporator. In the preferred usage, two air feeding openings are provided which are positioned such that one of them is close to the first side wall and the other one is close to the second side wall, in a manner close to the upper side of the drawered part which exists in the cooling part, in other words, between the drawered part and the second plate-like separation unit in a manner closer to the drawered part. However, the number of the air feeding openings can be increased and decreased in the desired manner. By means of this, the air that exists in the cooling part easily passes to the evaporator air input part. The air that exists in the cooling part is transferred to the evaporator air input part that exists in the evaporator by means of air feeding channels connected to the mentioned air feeding openings. In the preferred usage, there are two air feeding channels connected to the two air feeding openings. The air feeding channel, connected to the air feeding opening which is close to the first side wall, advances through the side of the air transfer part, which is close to the first side wall, in a parallel manner to the first side wall at the side where the air transfer part rear face exists. The air feeding channel, connected to the air feeding opening which is close to the second side wall, advances through the side of the air transfer part, which is close to the second side wall, in a parallel manner to the second side wall at the side where the air transfer part rear face exists. After the air feeding channel which is close to the first side wall and the air feeding channel which is close to the second side wall pass from the side of the air transfer part which is close to the first side wall and from the side of the transfer part which is close to the second side wall, they widen and orient towards the evaporator air input part and reach the evaporator air input part. In other words, the air feeding channel which is close to the first side wall and the air feeding channel which is close to the second side wall are meeting in the evaporator air input part and are connected to the evaporator air input part in a manner closing the evaporator air input part. The number of air feeding channels can be increased and decreased in a proportional manner with the number of air feeding openings. The cooling compartment can be mentioned as the volume which exists in the cooling part and which covers the materials desired to be cooled. Preferably, the cooling compartment can also be mentioned as the volume which remains between the plate-like separation unit and the second plate-like separation unit or between the inner upper wall and the plate-like separation unit or the second plate-like separation unit or the drawered part and the plate-like separation unit or the second plate-like separation unit.

[0064] In this detailed description, the subject matter is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

[0065] As can be seen in FIGS. 1 and 5, the subject matter cooling device 1 contains a cooling part 2, an inner rear wall 2.1 that exists in the cooling part 2, at least one air distribution opening 3 provided at the inner rear wall 2.1, at least one air channel 5 through which the cold air passes and which is suitable for being connected to the other side of the inner rear wall 2.1 which does not face the cooling part 2 in a manner covering the air distribution opening 3, at least one air passage gap 5.6 configured to correspond to the air distribution opening 3 at the air channel 5, at least one air transfer part 6.1 which is suitable for being connected to the air channel 5 and which provides transfer of the cold air, formed by at least one evaporator 7 by means of at least one fan 6, to the air channel 5, at least one air feeding opening 8 positioned at the inner rear wall 2.1 and adapted for passing the air, which exists in the cooling part 2, to at least one evaporator air input part 7.1 which exists in the evaporator 7, by means of at least one air feeding channel 8.1, and at least one air channel surface extension 5.2 which can exist at an air channel front surface 5.1 in order to allow passage of different amounts of air, by at least two air distribution openings 3, which are equivalent to each other, from the air channel 5 to the cooling part 2.

[0066] With reference to FIGS. 1 and 2, the cooling device 1 contains the cooling part 2 formed by the inner rear wall 2.1, an inner upper wall 2.2, an inner lower wall 2.3, a first side wall Y1 and a second side wall Y2. The cooling part 2 covers the suitable volume for placing the materials desired to be cooled. There is a front opening 13 which enables access to the cooling part 2 by the user. The front opening 13 exists at the opposite side of the inner rear wall 2.1 that exists in the cooling part 2. The cooling device 1 contains at least one door not shown in the figures connected to the cooling part 2 in a rotatable manner by means of hinges. In case the door is closed, the front opening 13 is completely closed, in other words, access to the cooling part 2 from outside is prevented. As can be seen in FIG. 2, there is a plate-like separation unit 9 which is suitable for being placed in a removable manner to the cooling compartment 2 and which separates the volume, covered by the cooling part, into parts in a manner forming at least one cooling compartment 10. The plate-like separation unit 9 can be connected to the cooling part 2 in a manner holding to the first side wall Y1 and the second side wall Y2. The holding can be provided by means of wall protrusions provided at the first side wall Y1 and at the second side wall Y2 and by means of bracket-like structures not shown in the figures. As can be seen in FIG. 1, there is at least one air distribution opening 3, positioned at the inner rear wall 2.1, in the cooling part 2. While the air distribution openings 3 seem to be exactly at the same size as each other on the inner rear wall 2.1 in the cooling part 2, in other words, while said air distribution openings 3 seem to be equivalent, the air distribution openings 3 can be configured in a manner able to provide different amounts of cold air passage to the cooling part 2 from at least one air channel 5 which can be seen in FIG. 5. This shall make contribution for enhancing of the aesthetical appearance of the inner rear wall 2.1 which exists at the cooling part 2. Additionally, since different amount of cold air input is possible to the cooling part 2 through the air distribution openings 3, the temperature differences which may occur in the cooling part 2 are prevented. In other words, the temperature balance in the cooling part 2 can be provided.

[0067] As can be seen in FIG. 1, the air distribution grid 4 is connected to the air distribution opening 3.

[0068] There is at least one inclined guiding part 4.1 and at least one flat guiding part 4.2 providing distribution of the cold air, which comes from the air distribution opening 3, to the volume covered by the cooling part 2. The mentioned inclined guiding part 4.1 enables distributing of the cold air towards the first side wall Y1 and towards the second side wall Y2. The flat guiding part 4.2 enables distribution of the cold air to the cooling part 2. As can be seen in FIG. 1, at the inner rear wall 2.1 provided in the cooling part 2, there is at least one evaporator cover 7.2 provided in a manner forming a part of the inner rear wall 2.1. The mentioned evaporator cover 7.2 hides at least one evaporator 7, at least one fan 6 and at least one air transfer part 6.1, positioned at the other side D of the inner rear wall which does not face the cooling part, when viewed from the cooling part 2 side. At the inner rear wall 2.1, there is at least one air feeding opening 8 which is close to a drawered part upper side 12.1 which exists in the cooling part 2. The mentioned air feeding opening 8 makes contribution for passing of the air, which exists in the cooling part 2, to at least one evaporator air input part 7.1, which exists in the evaporator 7, by means of the air feeding channel 8.1. As can be seen in FIGS. 1 and 2, there are two air feeding openings 8 in the preferred usage. The mentioned numbers can be increased or decreased as desired. While one of the air feeding openings 8 is positioned in a manner closer to the first side wall Y1, the other one is positioned in a manner closer to the second side wall Y2. However, it can be possible that the positions are arranged in the desired manner. As can be seen in FIG. 1 and FIG. 2, there are totally six air distribution grids 4 at the inner rear wall 2.1 of the cooling part 2. The six air distribution grids 4 are connected to six air distribution openings 3. The mentioned numbers can be increased or decreased as desired. The air distribution openings 3 are positioned between the inner upper wall 2.2 and at least one drawered part 12 which exists in the cooling part 2. In other words, the air distribution openings 3 are positioned between the evaporator cover 7.2 and the inner upper wall 2.2. In a possible embodiment of the invention, there can be drawered part 12 which enables storage of various materials in the cooling part 2. The drawered part 12 can be positioned in a manner corresponding to the evaporator cover 7.2 which can close the evaporator 7, the fan 6 and the air transfer part 6.1 in the cooling part 2.

[0069] With reference to FIG. 2, the cooling device 1 has at least one air distribution opening 3 positioned to the inner rear wall 2.1 in a manner corresponding to the lower side of a plate-like separation unit 9 which is suitable for providing formation of the cooling compartment 10 by being placed to the cooling part 2 in a removable manner. By means of this, cold air input is provided through the lower side of the plate-like separation unit 9 from the air channel 5 to the cooling part 2. Thus, the fluctuations in the temperature degree which may occur in the cooling compartment 10 which occurs by placing the plate-like separation unit 9 to the cooling part 2 are prevented, and the prevention of the temperature differences, which may occur in the cooling part 2, is supported.

[0070] Since the air distribution opening 3 exists at the lower side of the plate-like separation unit 9 in a manner close preferably to the plate-like separation unit 9, the cold air, which comes from the air channel 5 and which enters the cooling part 2 through the air distribution opening 3, is prevented from meeting with the material placed to the cooling compartment 10 in order to be cooled. Thus, blocking of cold air input through the air distribution opening 3 from the air channel 5 to the cooling part 2 is prevented.

[0071] As can be seen in FIG. 2, the cooling device 1 contains a plate-like separation unit 9 and a second plate-like separation unit 9.1 which is suitable for separating the cooling part 2 in a manner forming the cooling compartment 10. In a possible embodiment of the present invention, the cooling device 1 contains at least one air distribution opening 3 placed to the cooling part 2 in a removable manner and positioned to the inner rear wall 2.1 such that each of them corresponds to the air passage gap 5.6 that exists in the air channel 5, in a parallel manner to a second plate-like separation unit 9.1, in a manner corresponding to the lower side of the second plate-like separation unit 9.1 which is suitable for providing formation of the cooling compartment 10. By means of this, the temperature degree differences which may occur in the cooling part are prevented. In the preferred usage, the air distribution openings 3 are positioned in a manner corresponding to the air channels 5. The number of air channels 5, thus, the number of air distribution openings 3 corresponding to the air channel can also be increased in accordance with the size of the cooling device 1, namely, in accordance with the width of the cooling device 1. Since the air distribution opening 3 exists at the lower side of the second plate-like separation unit 9.1 preferably in a close manner to the second plate-like separation unit 9.1, the cold air, which comes from the air channel 5 and which enters the cooling part 2 through the air distribution opening 3, is prevented from meeting with a material placed to the cooling compartment 10 in order to be cooled. Thus, blockage of input of cold air from the air channel 5 to the cooling part 2 through the air distribution opening 3 is prevented.

[0072] There are two air distribution openings 3 in a parallel manner to the plate-like separation unit 9 at the lower side of the plate-like separation unit 9 which can also be seen in FIG. 1. In the preferred usage, in the cooling part, there is the plate-like separation unit 9 and the second plate-like separation unit 9.1. The mentioned plate-like separation unit 9 can be positioned in a manner remaining in the region which exists between the drawered part 12 and the inner upper wall 2.2 in the cooling part. However, if preferred, the mentioned plate-like separation unit 9 can be positioned in a manner having equal distance to the drawered part 12 and the inner upper wall 2.2. The mentioned second plate-like separation unit 9.1 can be positioned in a manner closer to the drawered part 12 between the drawered part 12 and the plate-like separation unit 9 in the cooling part 2. At the lower side of the second plate-like separation unit 9.1, there are two air distribution openings 3 in a manner parallel to the plate-like separation unit 9.1. Thus, there are totally four air distribution openings 3 positioned to the lower side of the plate-like separation unit 9 and the second plate-like separation unit 9.1 in a parallel manner to the plate-like separation unit 9 and the second plate-like separation unit 9.1 in a manner corresponding to the four air passage gaps 5.6 that exist in the air channels 5 that can be seen in FIG. 5. Thus, there are also four air passage gaps 5.6 at the air channel 5, which correspond to the four air distribution openings 3. In the preferred usage, the plate-like separation unit 9 and the second plate-like separation unit 9.1 can be shelf produced from glass material. However, if preferred, production from a different material is also possible. Moreover, the mentioned numbers can be increased or decreased in the desired manner.

[0073] With reference to FIG. 5, the cooling device 1 contains at least one air distribution opening 3 positioned to the inner rear wall 2.1 in a manner corresponding to the lower side of the inner upper wall 2.2 which exists in the cooling part 2. By means of this, cold air input from the air channel 5 to the cooling part through the lower side of the inner upper wall 2.2 of the cooling device 1 can be possible. Thus, the fluctuations in the temperature degree at the lower side of the inner upper wall 2.2 of the cooling part 2 are prevented, and the prevention of the temperature differences, which may occur in the cooling part 2, is supported.

[0074] In a preferred usage, as can be seen in FIGS. 1 and 2, the cooling device 1 comprises at least two air distribution openings 3 positioned in a manner corresponding to the lower side of the inner upper wall 2.2 and in a parallel manner to the inner upper wall 2.2 and where each of said air distribution openings3 are positioned to the inner rear wall 2.1 in a manner corresponding to at least one air channel 5. By means of this, the temperature degree differences that may occur in the cooling part 2 are prevented. Since the air distribution opening 3 is positioned at the lower side of the inner upper wall 2.2 preferably in a manner close to the inner upper wall 2.2, the cold air, which comes from the air channel 5 and which enters the cooling part 2 through the air distribution opening 3, is prevented from meeting with any obstacle, for instance, with a material desired to be cooled. Thus, blockage of input of cold air from the air channel to the cooling part through the air distribution opening 3 is prevented. Here, the mentioned inner upper wall 2.2 can also be mentioned as a ceiling of the cooling part 2. Here, the mentioned inner rear wall 2.2 can also mentioned as a rear side of the cooling part 2. In other words, there is the front opening 13 at the opposite side of the inner rear wall 2.1 that exists in the cooling part 2.

[0075] As can be seen in FIG. 5, the cooling device 1 has at least two air channels 5, which are suitable for being placed to the other side D of the inner rear wall 2.1 which does not face the cooling part 2 and in an orthogonal manner to the inner upper wall 2.2 such that the at least two air channels 5 are placed in a parallel manner to each other and there is a distance in between in the width direction x and they cover the air distribution openings 3. By means of this, the temperature degree differences that may occur in the cooling part 2 are prevented. In accordance with the size of the cooling device 1, in other words, in accordance with the size of the cooling device 1 in the width direction x, the number of air channels 5, which make contribution for coming of cold air to the cooling part 2, can be increased. By means of this, the cooling part 2 is more rapidly cooled. In the preferred usage, the air channels 5 are positioned to the other side D of the inner rear wall 2.1 which does not face the cooling part 2 and in an orthogonal manner to the inner upper wall 2.2 such that the air channels 5 are placed in a parallel manner to each other and there is a distance in between in the width direction x. Additionally, the air channels 5 can be positioned in a manner parallel to a first side wall Y1 and a second side wall Y2 forming the cooling part 2 and such that a distance remains between the first side wall Y1 and the second side wall Y2 in the width direction x. Here, the mentioned distance can be described as the distance in the width direction which may occur between at least two air channels 5 and between the air channel 5 and the cooling part 2 first side wall Y1 and second side wall Y2 in accordance with the size of the cooling device 1, in other words, in accordance with the width of the cooling device 1.

[0076] As can be seen in the detailed view given in FIG. 5, at the lower side of the inner upper wall 2.2 of the cooling part 2 of the cooling device 1, there are the air passage gap 5.6 and the air distribution opening 3 which have the same size as each other and which are suitable for providing cold air passage to the cooling part 2 from the air channel 5. By means of this, the cold air which comes from the air channel 5 can enter the cooling part 2 without any obstacle, namely without delimiting the cold air passage. Here, by means of the statements of the air passage gap 5.6 and the air distribution opening 3 which have the same size as each other, it is desired to be described that the air passage gap 5.6 and the air distribution opening 3 have the same sizes in the width direction x and in the height direction z. However, in a possible embodiment of the invention, at the lower side of the inner upper wall 2.2, the cooling part 2 can comprise air passage gap 5.6 configured to be bigger in the height direction z when compared with the air distribution opening 3 which is suitable for providing cold air passage from the air channel 5 to the cooling part 2. By means of this, it can be possible that the size of the air passage gap 5.6 provided in the air channel 5 in the height direction z is bigger than the size of the air distribution opening 3 in the height direction z. In this case, the size in the width direction x can remain the same. Thus, since the air passage gap 5.6 is bigger that the air distribution opening 3, the amount of cold air which comes to the air distribution opening from the air passage gap 5.6 can be increased.

[0077] As can be seen in another detailed view given in FIG. 5, in a possible embodiment of the present invention, the cooling device 1 comprises an air channel surface extension 5.2 which is suitable for connecting to the air channel front surface 5.1, that exists at the air channel 5 at the lower side of the plate-like separation unit 9, in a manner partially closing the air passage gap 5.6 in the height direction z and which provides that the air passage gap 5.6 is smaller than the air distribution opening 3 in a manner providing partial cold air passage from the air channel 5 to the cooling part 2. By means of this, since the cold air, which comes from the air channel 5, meets with the air channel surface extension 5.2, namely meets with an obstacle, input of cold air to the cooling part 2 from the air distribution opening 3 is delimited. The air passage gap 5.6 is partially closed in the height direction z by means of the air channel surface extension 5.2. By means of the connection of the air channel surface extension 5.2 to the air channel front surface 5.1, it can be possible that the air passage gap 5.6 is closed with the desired proportion. It can be possible that the air channel surface extension 5.2 can be connected to the air channel front surface 5.1 on or under the air passage gap 5.6 or both on and under the air passage gap 5.6 in the height direction z. This facilitates closing of the air passage gap 5.6 at the air channel front surface 5.1 with the preferred size in the height direction. By means of this, the air passage gap 5.6 can be smaller than the air distribution opening 3. In other words, it can be possible that the cold air, which comes from the air channel 5, is prevented by means of the air channel surface extension 5.2, and the cold air can partially enter the cooling part 2.

[0078] In a possible embodiment of the invention, there is the air channel surface extension 5.2 which is suitable for being produced one-piece with the air channel front surface 5.1 in a manner partially closing the air passage gap 5.6, that exists at the air channel 5 at the lower side of the plate-like separation unit 9, in the height direction z and which provides that the air passage gap 5.6 is smaller than the air distribution opening 3 in a manner providing partial cold air passage from the air channel 2 to the cooling part 2. By means of this, since the cold air, which comes from the air channel 5, meets with the air channel surface extension 5.2, namely meets with an obstacle, the input of cold air to the cooling part 2 from the air distribution opening 3 is delimited. The air passage gap 5.6 is partially closed in the height direction z by means of the air channel surface extension 5.2. The air channel surface extension 5.2 can be produced in one-piece manner with the air channel front surface 5.1. Thus, it can be possible to produce an air channel 5 which has an air passage gap 5.6 with the desired dimension. This provides advantage in terms of cost. Moreover, by providing the air passage gap 5.6 to be smaller than the air distribution opening 3, it can be possible that the cold air, which comes from the air channel 5, partially enters the cooling part 2.

[0079] Here, by the statement “partially”, it is desired to describe that a part of the air passage gap 5.6 is closed in the height direction. By means of this, it is desired to describe that a partial cold air passage from the air passage gap 5.6 to the air distribution opening 3 and thus to the cooling part 2 is possible.

[0080] With reference to FIG. 4, the cooling device 1 contains an air channel 5 formed by a single compartment 5.8 which is suitable for transfer of cold air. By means of this, the cold air, which comes from the air channel 5, is transferred to the air passage gap 5.6 mentioned in FIG. 5 such that the cold air is not interrupted, in other words, the cold air flow is not prevented. With reference to FIG. 3, the cooling device 1 comprises at least one support part 5.5 which provides separation of the air channel 5 into at least two compartments and configured between the air channel front surface 5.1 and an air channel rear surface 5.7 in a manner preventing deterioration of the form of the air channel 5 and in an orthogonal manner to the air channel front surface 5.1 and to the air channel rear surface 5.7. By means of this, deterioration of the form of the air channel 5 is prevented. Thus, narrowing of the cross-section of the air channel 5 from which the cold air comes is prevented. This condition increases the usage lifetime and efficiency of the air channel 5. The support parts 5 can be more than one in number. Thus, if preferred, the air channel 5 can also be separated into more than two compartments. Moreover, the air channel front surface 5.1 and the air channel rear surface 5.7 can be parallel to each other. As can be understood from FIG. 3 and FIG. 4, the air channel 5 can have a rectangular prism shape in the preferred usage, however, it can also be possible that said air channel 5 has a different shape. As can be seen in FIG. 3, the air channel 5 which has a rectangular prism shape has been separated into two equal compartments by means of the support part 5.5. In other words, the air channel has been separated into a first compartment 5.3 and a second compartment 5.4. The first compartment 5.3, the second compartment and the support part 5.5 that exists between the first compartment 5.4 and the second compartment can be seen at the inner rear wall 2.1 of the cooling part 2 when the air distribution grid 4 is removed. The flat guiding part 4.2, which exists in the air distribution grid 4 which can be seen in FIG. 8 in details, is positioned in a manner corresponding to the support part 5.5.

[0081] With reference to FIG. 6, by removing the evaporator cover 7.2 which exists at the inner rear wall 2.1 in the cooling part, the fan 6, the air transfer part 6.1 and the evaporator 7 become visible. In an application of the invention, there is evaporator 7 which corresponds to the drawered part 12, and an evaporator cover 7.2 positioned at the inner rear wall 2.1 in the cooling part 2 in a manner closing the air transfer part 6.1. In other words, the evaporator cover 7.2 forms the part of the inner rear wall 2.1 which corresponds to the drawered part 12. By means of this, when desired, the evaporator cover 7 is removed from the cooling part 2, and access can be provided to the evaporator 7 and to the air transfer part 6.1 and thus to the fan 6. Moreover, the evaporator cover 7.2 also provides an aesthetic appearance.

[0082] With reference to FIG. 7, the cooling device 1 contains at least one air distribution grid 4 connected to the air distribution opening 3 and which provides the cold air, which passes to the cooling part 2 through the air channel 5, to be distributed to the cooling part 2. By means of this, the cold air, which comes from the air channel 5 and which passes through the air passage gap 5.6 and the air distribution opening 3, can be easily distributed to the cooling part 2. By means of this, the temperature degree difference that exists inside the cooling device 1 can be decreased.

[0083] With reference to figures between FIGS. 7 and 11, the air distribution grid 4 comprises at least one inclined guiding part 4.1 which provides distributing of the cold air, which comes from the air channel 5, to the cooling part 2. By means of this, the cold air, which comes through the air channel 5 and which passes through the air passage gap 5.6 and the air distribution opening 3, can be easily distributed to the cooling part 2. In other words, cold air can also be transferred towards the first side walls Y1 and the second side wall Y2 of the cooling part 2. By means of this, the temperature degree difference that exists inside the cooling part 2 of the cooling device 1 can be decreased.

[0084] In a possible embodiment of the invention, the air distribution grid 4 which exists in the cooling device 1 contains at least one flat guiding part 4.2 which provides distributing of the cold air, which comes from the air channel 5, to the cooling part 2. By means of this, the cold air, which comes from the air channel 5 and which passes through the air passage gap 5.6 and the air distribution opening 3, can be easily distributed to the cooling part 2. By means of this, the temperature degree difference inside the cooling device 1 can be decreased.

[0085] As shown in the figures between FIGS. 8 and 11, the cooling device 1 contains at least one connection element 4.3 which provides connection of the air distribution grid 4 to the air distribution opening 3. By means of this, the air distribution grid 4 can be snap-fixed to the air distribution opening 3. In the preferred usage, the air distribution grid 4 can be connected to the air distribution opening 3 by means of at least one connection element 4.3. Preferably, the connection element 4.3 can be connection tab. However, if preferred, different connection elements 4.3 like adhesive, screw can also be used. The mentioned connection tab can be positioned on a first part 4.4 or on a second part 4.5 of the air distribution grid 4 or both on the first part 4.4 and on the second part 4.5 or on the lateral part 4.7. In the preferred usage, both on the first part 4.4 and on the second part 4.5, at least one connection tab is formed in a one-piece manner with the air distribution grid 4. In the preferred application of the invention, there are totally four connection tabs in the air distribution grid 4. As can be understood in FIG. 11, in order to create connection tab form both in the first part 4.4 and in the second part 4.5, forming process, namely cutting process can be realized in a manner forming connection tab in the first part 4.4 and in the second part 4.5. This prevents usage of extra material for the connection tab, thus, this prevents occurrence of extra cost. In an application of the invention, the air distribution grid 4 is connected to the air distribution opening 3 that exists in the inner rear wall 2.1 of the cooling part 2. In this step, the holding surface that exists in the air distribution grid 4 prevents sliding of the air distribution grid 4 from the inner rear wall 2.1 towards the air passage gap 5.6, and provides a more stable connection. The air distribution grid 4 is in the form of a channel which narrows from the inner rear wall 2.1 towards the air passage gap 5.6. More specifically, the air distribution grid 4 is seen in oblong form at the inner rear wall 2.1. However, the oblong form creates a channel structure which can be seen in FIG. 11 by inclining of the lateral parts towards the flat guiding part 4.2 from the inner rear wall 2.1 towards the air passage gap 5.6. However, by advancing the lateral parts towards the flat guiding part from the inner rear wall towards the air passage gap, in other words, a channel structure, which narrows towards the air passage gap, is formed from the oblong form that exists at the inner rear wall. However, the air distribution grid 4 can also be made in different forms. Moreover, the air distribution grid 4 also makes contribution for the aesthetic appearance in the cooling part 2. The air distribution grid 4 can be produced from plastic material. By means of this, the desired shape can be given to the air distribution grid 4. In the preferred usage, the air distribution grid 4 formed by two inclined guiding parts 4.1 and one flat guiding part 4.2 is used. The inclined guiding parts 4.1 have inclined structure in a manner close to the lateral parts 4.7 of the air distribution grid 4 and in a manner providing guiding of the cold air to the cooling part 2 first side wall Y1 and the second side wall Y2. The flat guiding part 4.2, in the preferred usage, is preferably at equal distance to said inclined guiding parts 4.1 between at least two inclined guiding parts 4.1. The at least one inclined guiding part 4.1 and the at least one flat guiding part 4.2 are positioned between the first part 4.4 and the second part 4.5 of the air distribution grid 4.

[0086] As can be seen in FIG. 3 and FIG. 5, in a possible embodiment of the invention, an insulation material 11 can be connected along the air channel 5, between the air channel 5 and the other side D of the inner rear wall 2.1 which does not face the cooling part 2. The insulation material 11 can be selected from EPS Expanded Polystyrene. By means of this, due to the temperature degree difference between the cold air, which passes through the air channel 5, and the air which exists in the cooling part 2, condensation which may occur at the inner rear wall 2.1 of the cooling part 2, in the parts corresponding to the air channels 5, is prevented. In other words, formation of droplets at the parts corresponding to the air channels 5 at the inner rear wall 2.1 of the cooling part 2 is prevented. By means of this, user satisfaction increases and aesthetic appearance is obtained in the cooling part 2. Also at the insulation material, there are openings at the parts which correspond to the air passage gap and the air distribution opening. In a possible embodiment of the invention, the air channel 5 can be connected by means of double-sided band to the other side D of the inner rear wall 2.1 which does not face the cooling part 2. If preferred, instead of the double-sided band, connection can be provided by means of engagement connection between the air channel 5 and the other side D of the inner rear wall 2.1 which does not face the cooling part 2.

[0087] In an application of the invention, after the air channel 5 is connected to the other side D of the inner rear wall 2.1 which does not face the cooling part 2, liquid polyurethane is added to the air channel rear surface 5.7. When the liquid polyurethane solidifies, the air channel rear surface 5.7 is completely covered. Access to the air channel 5 through the air channel rear surface 5.7 is not possible. By means of this, insulation can be provided between the cooling part 2 provided in the cooling device 1 and the outer medium where the cooling device 1 exists. Contribution is made for preservation of the cooling function of the cooling part 2. At this point, the support part 5.5, which can exist in the air channel 5, prevents flexing of the air channel rear surface 5.7 towards the air channel front surface 5.1 as a result of addition of polyurethane from the air channel rear surface 5.7.

[0088] In the preferred usage, there are two air distribution openings 2.2 which are parallel to the inner upper wall 2.2 in a manner corresponding to the lower side of the inner upper wall 2.2. At the same time, the air distribution openings 2 are positioned in a manner corresponding to the air passage gap 5.6 which exists in the air channels 5. The air distribution opening 3 and the air passage gap 5.6 which exists in the air channel 5 are at the same size as each other in the height direction z and in the width direction x. It can also be possible that the air passage gap 5.6, which exists at the air channel 5, is bigger than the air distribution opening 3 in the height direction z and in the width direction x. Therefore, the air distribution openings 3 positioned in a manner corresponding to the lower side of the inner upper wall 2.2 is the part where the cold air input to the cooling part 2 is at maximum. In the preferred application also seen in FIG. 5, the air passage gap 5.6 which corresponds to the air distribution openings 3 that exist at the lower side of the inner upper wall 2.2 is nearly 10 mm in the height direction z. Cold air is inclined to collapse due to its structure. By means of this, by collapsing of the cold air, which exists at the lower side of the inner upper wall 2.2, towards the drawered part 12, the temperature degree difference which may occur in the other parts of the cooling part 2 and the lower side of the inner upper wall 2.2 is prevented. Therefore, in the preferred application, the air distribution openings 3 positioned in a manner corresponding to the lower side of the inner upper wall 2.2 have been configured in a manner providing maximum cold air input to the cooling part 2.

[0089] The plate-like separation unit 9 which can also be seen in FIG. 5 is configured such that the air passage gap 5.6, provided at the air channel front surface 5.1 which corresponds to the air distribution opening 3 positioned at the lower side of the plate-like separation unit 9, is nearly 6 mm in the height direction. In the preferred usage, the air passage gap 5.6, which exists at the air channel front surface 5.1 corresponding to the air distribution opening 3 positioned at the lower side of the second plate-like separation unit 9.1, is configured such that it is nearly 6 mm in the height direction not shown in the figures. The configuration processes are possible by means of the air channel surface extension 5.2.

[0090] In the preferred application of the invention, cold air passage occurs with proportion of nearly 42% through the air passage gaps 5.6 which are nearly 10 mm in the height direction z corresponding to the air distribution openings 3 positioned at the lower side of the inner upper wall 2.2. Cold air passage with proportion of nearly 36% occurs through the air passage gaps 5.6 which are nearly 6 mm in the height direction z and which correspond to the air distribution openings 3 positioned at the lower side of the plate-like separation unit 9. Cold air passage with proportion of nearly 22% occurs through the air passage gaps 5.6 which are nearly 6 mm in the height direction z and which correspond to the air distribution openings 3 positioned at the lower side of the second plate-like separation unit 9.1. Thus, the cold air which comes from the air channel 5 can pass to the cooling part 2 at proportion of 100% totally. By increasing the plate-like separation units 9, thus, by increasing the air distribution openings 3 positioned at the lower side of the plate-like separation units 9.1 and by increasing the air passage gaps 5.6 which correspond to said air distribution openings, the proportions can change such that the total thereof is 100%. Moreover, it is assumed that the size of the air passage gaps 5.6 in width direction x is fixed. In the preferred usage, the size of the air passage gaps 5.6 in the width direction x can be nearly 80 mm.

[0091] In the preferred usage, cold air, which is between −8 and −10 centigrade degrees, comes from the air channel 5. In case the air passage gaps 5.6, that exist in the air channel 5 that exists at the lower side of the plate-like separation unit 9, of the second plate-like separation unit 9.1 and of the inner upper wall 2.2, is nearly 10 mm in the height direction z, air passage with proportion of nearly 33.3% occurs through each air passage gap 5.6 to the cooling part 2 such that the total thereof is 100%.

[0092] With reference to FIG. 6 and FIG. 12, in the preferred usage, the air transfer part 6.1 is formed by connecting at least one air transfer part front face 6.1.1 and at least one air transfer part rear face 6.1.2 to each other. By means of this, the air transfer part 6.1 can also be described as a fan housing, and there can be a pressure chamber in the air transfer part 6.1.

[0093] With reference to FIG. 12, the air which exists in the cooling part 2 is transferred to the evaporator air input part 7.1 that exists in the evaporator 7 by means of air feeding channels 8.1 connected to said air feeding openings 8. In the preferred usage, there are two air feeding channels 8.1 connected to the two air feeding openings 8. As can be seen in FIG. 12, the air feeding channel 8.1, connected to the air feeding opening 8 which is close to the first side wall Y1, advances through the side of the air transfer part 6.1, which is close to the first side wall Y1, in a parallel manner to the first side wall Y1 at the side where the air transfer part rear face 6.1.2 exists. After the air feeding channel 8 which is close to the first side wall Y1 and the air feeding channel 8 which is close to the second side wall Y2 pass from the side of the air transfer part 6.1 which is close to the first side wall Y1 and from the side of the air transfer part 6.1 which is close to the second side wall Y2, the air feeding channels 8 widen and orient towards the evaporator air input part 7.1 and reach the evaporator air input part 7.1. In other words, the air feeding channel 8 which is close to the first side wall Y1 and the air feeding channel 8 which is close to the second side wall Y2 meet at the evaporator air input part 7.1 and connect to the evaporator air input part 7.1 in a manner closing the evaporator air input part 7.1. The number of air feeding channels 8.1 can be increased and decreased in a proportional manner with the number of air feeding openings 8.

[0094] The cooling compartment 10 can be mentioned as the volume that exists in the cooling part 2 and that covers the materials desired to be cooled. Preferably, the cooling compartment 10 can be mentioned as the volume that exists between the plate-like separation unit 9 and the second plate-like separation unit 9.1 or between the inner upper wall 2.2 and the plate-like separation unit 9 or the second plate-like separation unit 9.1 or between the plate-like separation unit 9 or the second plate-like separation unit 9.1 and the drawered part 12.

[0095] Here, by means of the mentioned “cooling device 1”, it is desired to describe a device, particularly a household cooling device, a refrigerator used in houses and which has a cooling cycle and which can realize cooling function.

[0096] Here, by means of the mentioned “the other side D of the inner rear wall 2.1 which does not face the cooling part 2”, it is desired to describe the other side D of the inner rear wall 2.1 which is not visible by a user who looks in a manner seeing the inner rear wall 2.1 which exists in the cooling part 2.

[0097] Here, by means of the mentioned “at least two air distribution openings 3 which are equivalent to each other”, it is desired to describe that the air distribution openings 3 are the same as each other in a width direction x, in a depth direction y and in a height direction z.

[0098] Here, by means of the mentioned “air transfer part 6.1”, a part is desired to be described which can also be mentioned as a fan housing and wherein a pressure chamber exists.

[0099] In a possible embodiment of the invention, the cooling device 1 is in rectangular shape configured such that the air distribution openings 3, that exist at the inner rear wall 2.1 in the cooling part, have the same size as each other in the width direction x and in the height direction z. By means of this, the user, who looks at the air distribution openings 3 from the cooling part 2, can see that all of the air distribution openings 3 positioned at the inner rear wall 2.1 are at the same size. This contributes to the aesthetic appearance of the cooling part 2. User satisfaction increases in this direction. Even though the air distribution opening 3 is preferably in rectangular shape, it can also be arranged in any shape. By means of this, the cross-section of the air distribution opening 3 is increased. Moreover, by means of the rectangular shape of the air distribution opening 3, the friction surface is reduced, and contribution is made in the direction of not decreasing the pressure of the cold air which comes from the air channel 5.
