SUMMARY OF THE INVENTION

It is accordingly an object of the invention to provide a home appliance, particularly a cooling device, having at least one air flow system, which overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type and which prevents the interaction of the air which is located in at least two subparts, moreover, in parts such as a drawer or compartment which is located in each subpart, during transfer of the cold air, provided preferably at different temperature degrees, in an independent manner from each other to at least two subparts which exist in a first part and/or in a second part of a cooling device and to parts such as a drawer or compartment which is located in each subpart, to the evaporator again and cooling of the cold air in the evaporator, and to prevent any clogging that may occur in the evaporator.

Another object of the present invention is to prevent non-homogenous frosting of the evaporator.

Another object of the present invention is to provide efficient usage of the evaporator.

Another object of the present invention is to reduce energy consumption in cooling devices.

In order to achieve the objects, the subject matter cooling device includes at least two subparts provided in at least one part which is suitable for storage of at least one material, a related inner rear wall provided in each subpart, at least one related cold air input part provided on the inner rear walls, an evaporator which exists in the related part and which provides formation of cold air, which is suitable for passage by using the related cold air input part to the related subpart, by using at least one related fan, at least one air transfer path which provides transfer of cold air for passage of cold air by using the related cold air input part from the evaporator to the related subpart, and at least one air feeding channel which provides transfer of the air, that exists in the related subpart, for feeding to the related air input part opening into at least one evaporator, by using at least one air feeding opening provided in the related subpart, the at least two air input parts opening into the evaporator are configured to be suitable for being provided in a manner substantially not overlapping with each other and in an aligned and side-by-side manner in a width direction.

In this way, the air fed to at least two air input parts opening into the evaporator is prevented from interacting with each other, in other words, prevented from mixing. Thus, in case air is fed at different temperature degrees to at least two input parts opening into the evaporator, frostings which may occur in the evaporator are prevented.

In a possible embodiment of the invention, the evaporator includes at least three air input parts opening into evaporator. Thus, air, which has different temperature value, can be fed to the evaporator, and interaction of at least three airs which are fed and which have different temperature values is prevented, and thus, undesired frostings in the evaporator will be prevented. The air, fed to the air input parts opening into the evaporator, is transferred to the evaporator for being cooled again. Thus, the air fed to the air input parts opening into the evaporator is less cold when compared with the cold air which comes from the cold air input parts.

In a possible embodiment of the invention, the first air input part, opening into an evaporator and provided in a manner corresponding to the middle part of the evaporator, among the at least three air input parts opening into the evaporator is configured to be bigger than the other air input parts opening into the evaporator.

The air input part opening into the evaporator is connected to the related subpart or to the compartment by at least one air feeding opening. Thus, the dimensions of the air input parts opening into the evaporator can be produced or adjusted in accordance with the required cooling capacity for the related subpart or compartment. In this way, energy efficiency can be provided.

In a possible embodiment of the invention, the evaporator is configured to include the second air input part opening into the evaporator and the third air input part opening into the evaporator where the second air input part and the third air input part have different sizes from each other or are equivalent to each other and are suitable for being positioned to two sides of the first air input part opening into the evaporator and provided in a manner corresponding to the middle part of the evaporator. In this way, in accordance with the required cooling capacity for each related subpart or compartment to which the air input part opening into the evaporator is connected by at least one air feeding opening, the air input parts opening into the evaporator can be produced or adjusted in terms of dimension. In this way, energy efficiency can be provided.

In a possible embodiment of the invention, at least two subparts, which are suitable for storage of at least one material, are provided in at least one first part. In this way, during feeding of the air, which exists in at least two subparts that exist in the first part, to the first evaporator, the air can be guided to air input parts opening into different evaporator. Thus, undesired frostings and clogging which may occur in the first evaporator can be prevented.

In a possible embodiment of the invention, at least two subparts, which are suitable for storage of at least one material, are provided in at least one second part. In this way, during feeding of the air, which exists in at least two subparts that exist in the first part, to the second evaporator, the air can be guided to air input parts opening into different evaporator. Thus, undesired frostings and clogging which may occur in the second evaporator can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the figures of the drawings in detail, it is seen that 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.

In order to achieve the object of the invention, the subject matter cooling device 1 includes at least two subparts 3, 4, 8.1, 8.2 provided in at least one part 2, 8 which is suitable for storage of at least one material. A related inner rear wall 17, 18 is provided in each subpart 3, 4, 8.1, 8.2. At least one related cold air input part 3.1, 4.1, 4.2, 9.1, 10.1, 11.1, 11.2 is provided on the inner rear walls 17, 18. An evaporator 5, 12 which is provided in the related part 2, 8 provides a formation of cold air, which is suitable for passage by the related cold air input part 3.1, 4.1, 4.2, 9.1, 10.1, 11.1, 11.2 to the related subpart 3, 4, 8.1, 8.2, by using at least one related fan 7, 14. At least one air transfer path 6, 15 provides a transfer of cold air for passage of cold air by using the related cold air input part 3.1, 4.1, 4.2, 9.1, 10.1, 11.1, 11.2 from the evaporator 5, 12 to the related subpart 3, 4, 8.1, 8.2. At least one air feeding channel 3.3, 9.4, 10.4 provides a transfer of the air, that exists in the related subpart 3, 4, 8.1, 8.2, for feeding to at least one related air input part opening into the evaporator 5.1, 12.2, 12.3, by using at least one air feeding opening 3.2, 4.3, 4.4, 9.3, 10.3, 11.3 provided in the related subpart 3, 4, 8.1, 8.2). At least two air input parts opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 are configured to be suitable for being provided in a manner substantially not overlapping with each other and in a lined and side-by-side manner in a width direction X.

In this way, the air fed to at least two air input parts 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 opening into the evaporator 5, 12 is prevented from interacting with each other, in other words, prevented from mixing. Thus, in case air is fed at different temperature degrees to at least two air input parts 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 opening into the evaporator 5, 12, frostings which may occur in the evaporator 5, 12 are prevented.

With reference to FIG. 1, it is seen that the subject matter cooling device 1 includes a first part 2 and a second part 8. The first part 2 is formed by a first subpart 3 and a second subpart 4. At the first subpart 3, there are preferably six cold air input parts 3.1. The cold air input parts 3.1 transfer the cold air, which comes from at least one cold air passage channel 3.4 positioned at the rear side of a first inner rear wall 17, to the first subpart 3. The cold air is formed by using a first evaporator 5, and can be transferred to the cold air passage channel 3.4 with the help of a first fan 7 and by using a first air transfer path 6. Then, the air that exists in the first subpart 3 is transferred to the first air input part opening into a first evaporator 5.1 which can be seen in FIG. 4 and which can be removed from FIG. 5, by the air feeding opening 3.2 and by the air feeding channel 3.3 connected to the opening. The first air input part opening into the first evaporator 5.1 can be seen through an imaginary window opened in FIG. 4. At the second subpart 4 that is provided in the first part 2, the cold air, that occurs in the first evaporator 5, enters the second subpart 4 by using the first fan 7 and by using a first cold air input part 4.1 and a second cold air input part 4.2. The air, that exists in the second subpart 4, is then fed back to the first evaporator 5 by using the second air input part opening into the first evaporator 5.2 and by using the third air input part opening into a first evaporator 5.3. As can be seen in FIG. 8, there is at least one first evaporator cover 19, which is removable, at the part of the first inner rear wall 17 which corresponds to the first evaporator 5. In the preferred usage, at the first part 2, there is at least one first air feeding opening 4.3 and at least one second air feeding opening 4.4 positioned on the first evaporator cover 19 in a manner corresponding to the second air input part opening into the first evaporator 5.2 and to the third air input part opening into the first evaporator 5.3. In the preferred usage, the first air feeding opening 4.3 and the second air feeding opening 4.4 are in rectangular form, but can also be produced in different forms. The first air feeding opening 4.3 and the second air feeding opening 4.4 can be produced in desired numbers. Moreover, as can be seen in FIG. 7, in the second subpart 4, there is a drawer part 21 in the part that corresponds to the first cold air input part 4.1, the second cold air input part 4.2, the first air feeding opening 4.3 and the second air feeding opening 4.4. The temperature values of the drawers which are provided in the drawer part 21 can be different from each other and from the first subpart 3. In the preferred applications, the temperature of the first subpart 3 can be between +2 and +8 Celsius degrees. The temperature degree of the drawer part 21 can be between −1 and +3 Celsius degrees. As seen in FIG. 7, there can be preferably two drawers in the drawer part 21.

As can be seen in FIG. 3, FIG. 7 and FIG. 8, the second part 8 is formed by a first compartment 9, a second compartment 10 and a third compartment 11. These compartments are independent from each other. As can be seen in FIG. 2 and FIG. 3, a second evaporator 12 is positioned in a manner corresponding to the rear side of a second inner rear wall 18 such that the second evaporator 12 corresponds to the third compartment 11. The cold air, produced in the second evaporator 12, enters the first compartment 9 through a first compartment cold air input part 9.1 by using a first compartment cold air passage channel 9.2 with the help of a second fan 14 and a second air transfer path 15. The air which exists in the first compartment 9 then passes to a first compartment air feeding channel 9.4 through a first compartment air feeding opening 9.3 and reaches the second air input part opening into the second evaporator 12.2 as can be seen in FIG. 4. The second air input part opening into the second evaporator 12.2 can be seen through an imaginary window opened in FIG. 4.

As can be seen in FIG. 2 and FIG. 3, the cold air, produced in the second evaporator 12, advances through a second compartment cold air passage channel 10.2 with the help of the second fan 14 and the second air transfer path 15 and reaches a second compartment cold air input part 10.1 and enters the second compartment 10. The air, that exists in the second compartment 10, then passes through a second compartment air feeding opening 10.3 and comes to the third air input part opening into the second evaporator 12.3, by using a second compartment air feeding channel 10.4. The third air input part opening into the second evaporator 12.3 can be seen through an imaginary window opened in FIG. 4.

As can be seen in FIG. 2 and FIG. 3, the cold air produced in the second evaporator 12 comes to the third compartment 11 through a third compartment first cold air input part 11.1 and a third compartment second cold air input part 11.2 that can be seen in FIG. 1, with the help of the second fan 14 and the second air transfer path 15. The air, that exists in the third compartment 11, then passes to the first air input part opening into the second evaporator 12.1 by using a third compartment air feeding opening 11.3. The temperature degrees of the independent compartments that exist in the second part 8 can be different from each other. For instance, while the first compartment 9 can be −18 Celsius degrees, the second compartment 10 can be between −18 Celsius degrees and +4 Celsius degrees. Moreover, also at the second part 8, there is a second evaporator cover 20 which is removable and which is provided at the part of the second inner rear wall 18 that corresponds to the third compartment 11. Thus, the third compartment first cold air input part 11.1, the third compartment second cold air input part 11.2 and the third compartment air feeding opening 11.3 can be positioned in a manner facing a second inner volume 23 on the second evaporator cover 20. With reference to FIG. 3 and FIG. 6, it is seen that the first compartment air feeding channel 9.4 and the second compartment air feeding channel 10.4 are positioned so as to be at the opposite direction of the second inner volume 23. Moreover, it can be understood that the first air input part opening into the second evaporator 12.1 is provided at the side where the second inner volume 23 is provided.

In a possible embodiment of the invention, the evaporator 5.12 includes at least three air input parts opening into evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3. Thus, feeding of air, which has different temperature values, to the evaporator 5, 12 becomes possible, and interaction of at least three air flows which are fed and which have different temperature values is prevented, thus, undesired frostings in the evaporator 5, 12 will be prevented. The air fed to the air input parts opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 is transferred to the evaporator 5, 12 to be cooled again. Thus, the air fed to the air input parts opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 is less cold when compared with the cold air which comes from the related cold air input parts 3.1, 4.1, 4.2, 9.1, 10.1, 11.1, 11.2.

In a possible embodiment of the invention, the first air input part opening into the evaporator 5.1, 12.1 and provided in a manner corresponding to the middle part of the evaporator 5, 12, among the at least three air input parts opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 is configured to be bigger than the other air input parts opening into the evaporator 5.2, 5.3, 12.2, 12.3. In this way, the dimensions of the air input parts opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 can be determined based on heat gains in the operating condition and the temperature adjusted in an energy test. The air input part opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 is connected to the related subpart 3, 4 or to the compartment 9, 10, 11 by using at least one air feeding opening 3.2, 4.3, 4.4, 9.3, 10.3, 11.3. Thus, the dimensions of the air input parts opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 can be produced or adjusted in accordance with the required cooling capacity for the related subpart 3, 4 or the compartment 9, 10, 11. In this way, energy efficiency can be provided.

In a possible embodiment of the invention, the evaporator 5, 12 is configured to include the second air input part opening into the evaporator 5.2, 12.2 and the third air input part opening into the evaporator 5.3, 12.3 where the second air input part 5.2, 12.2 and the third air input part 5.3, 12.3 have different sizes from each other or are equivalent to each other and are suitable for being positioned to two sides of the first air input part opening into the evaporator 5.1, 12.1 and provided in a manner corresponding to the middle part of the evaporator. In this way, in accordance with the required cooling capacity for each related subpart 3, 4 or compartment 9, 10, 11 to which the air input part opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 is connected by using at least one air feeding opening 3.2, 4.3, 4.4, 9.3, 10.3, 11.3, the air input parts opening into the evaporator 5.1, 5.2, 5.3, 12.1, 12.2, 12.3 can be produced or adjusted in terms of dimension. In this way, energy efficiency can be provided.

In a possible embodiment of the invention, at least two subparts 3, 4 which are suitable for storage of at least one material are provided in at least one first part 2. In this way, during feeding of the air, that exists in at least two subparts 3, 4 provided in the first part, to the first evaporator 5, the air can be guided to the air input parts 5.1, 5.2, 5.3 opening into different evaporators. Thus, undesired frostings and clogging which may occur in the first evaporator 5 can be prevented.

In a possible embodiment of the invention, at least two subparts 8.1, 8.2 which are suitable for storage of at least one material is provided in at least one second part 8. In this way, during feeding of the air, that exists in at least two subparts 8.1, 8.2 provided in the second part 8, to the second evaporator 12, the air can be guided to different the air input parts opening into evaporator 12.1, 12.2, 12.3.
