FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to a cooling device according to the preamble of the independent claim.

A cooling device is an electronic device which provides keeping of food without spoiling for a specific duration and which cools beverages and which has a chamber which is at least partially closed. Cooling devices operate by means of a cooling cycle. In general, a cooling cycle takes place in a cooler, and the changes, formed by suctioning of heat by a cooling fluid and afterwards emitting heat by the cooling fluid, are defined in a cooling cycle. In a cooling cycle, the low-pressure cooling fluid is increased to high pressure by the compressor and is transferred to condenser. Condensation takes place in the condenser, and transformation into low pressure liquid is realized by passing through the expansion valve, and from here, cooling is realized by means of the evaporator.

There are pluralities of units in the cooling cycle. Additionally, there are electronic elements like sensors, illumination elements on the cooling device. These electronic elements must be associated and controlled with a control unit. The control unit can be placed in parts like base, ceiling and side wall on the cooling devices.

DETAILED DESCRIPTION OF THE INVENTION

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.

Referring now to the figures of the drawings in detail and first, particularly to FIG. 1 thereof, there is shown a cooling device 10. In the subject-matter cooling device 10, items placed in at least one body 11 are cooled by means of a cooling cycle. The aim of realizing cooling in the cooling device 10 is to keep various items under environmental temperature in said body 11. The cooling cycle of the cooling device 10 is controlled by means of at least one control unit 20. The control unit 20 is essentially a PCB. Thus, the control unit 20 controls operation of various components provided on the cooling device 10. The control unit 20 on the cooling device 10 is located on an outer wall surface 12 of the body 11. The outer wall surface 12 is essentially a ceiling part of the body 11 away from the floor.

In FIG. 2, a representative perspective view of at least one container arrangement 30 positioned on the subject matter cooling device 10 is given. Accordingly, the container arrangement 30 is positioned on the body 11. The container arrangement 30 control unit houses at least one part of the control unit 20 and protects the control unit 20 from external factors. In order to be able to realize this, the container arrangement 30 has at least one control unit housing 31 and at least one carrier tray 32. The carrier tray 32 is in the form of a drawer. The control unit housing 31 is in the form of a chamber connected in a fixed manner on the cooling device 10 and wherein the carrier tray 32 can be positioned. The control unit 20 is positioned on the carrier tray 32. Thus, assembly and maintenance facility is provided to the control unit 20 as the carrier tray 32 is placed into and moved away the control unit housing 31.

In FIG. 3, a representative dismantled view of the container arrangement 30 provided on the subject-matter cooling device 10 is given. There is at least one inner gap 312 for the placement of the carrier tray 32 on the control unit housing 31. The inner gap 312 at least partially receives the carrier tray 32. A vertical part 314 and an upper wall 315 are provided on at least one side of the inner gap 312 on the control unit housing 31. The vertical part 314 essentially exists on both mutual sides of the inner gap 312. The carrier tray 32 can be placed to the inner gap 312. The placement of the carrier tray 32 to the inner gap 312 provided on the control unit housing 31 is a closed position II. The control unit housing 31, fixedly positioned on the body 11, is configured so that it at least partially surrounds the carrier tray 32 in the closed position II. The extending of the carrier tray 32 outwardly from a front wall 13 of the body 11 is at least one open position I. The front wall 13 is the side of the body 11 which faces the user under normal usage conditions of the cooling device 10. As the carrier tray 32 is moved between the closed position II and the open position I, maintenance and assembly can be realized for the container arrangement 30.

The control unit housing 31 contains at least one first connection element 311. The carrier tray 32 comprises at least one second connection element 321. The first connection element 311 and the second connection element 321 are configured to be associated with each other. In a possible embodiment of the present invention, the first connection element 311 is a guide opening. The second connection element 321 can be in the form of a pin formed in a manner able to enter into the guide opening. The first connection element 311, provided in the form of a guide opening, exists mutually on the vertical parts 314 of the control unit housing 31. Thus, as the second connection element 321 is slid on the first connection element 311, the container arrangement 30 can displace between the open position I and the closed position II. The first connection element is 311 being an essentially L-shaped guide opening. Thus, sliding displacement of the second connection element 321 in the opening of the first connection element 311 is provided. The first connection element 311 has a first guiding portion 311a extending longitudinally and a second guiding portion 311b extending in a direction perpendicular to the first guiding portion 311a at an end of the first guiding portion 311a. Thus, sliding of the second connection element 321 in the first guiding portion 311a and locking in the second guiding portion 311b are provided. However, in alternative embodiments, the cooling device 10 can be produced also in different shapes in order to displace between the open position I and the closed position II.

In FIG. 4, a representative perspective view of the container arrangement 30 provided on the subject-matter cooling device 10 is given where the container arrangement 30 is in the open position I. While the container arrangement 30 is in the open position I, it is positioned in a manner facing outwardly from the front wall 13 such that servicing process can be applied to the control unit 20. In the container arrangement 30, there is at least one second guiding portion 311b for keeping the carrier tray 32 in the open position I with respect to the control unit housing 31. The second guiding portion 311b keeps the carrier tray 32 continuously in the open position I. Therefore, second guiding portion 311b is configured to prevent essentially the movement of the second connection element 321 on the first connection element 311. In case the first connection element 311 is provided in a guide opening form, the second guiding portion 311b is provided in the form of a pocket which is adjacent to the guide opening. In case the second connection element 321 is slid on the first connection element 311 and passes to the open position I, the second connection element 321 is stopped by the second guiding portion 311b and movement of the second connection element 321 in the guide opening is prevented. In the invention, the second guiding portion 311b is configured so that the carrier tray 32 is being in a rest position in which an angle is provided between the carrier tray 32 and the outer wall surface 12. Thus, the undesired movement of the carrier tray 32 in the servicing process is prevented.

In FIG. 5, a representative perspective view of the container arrangement 30 provided on the subject-matter cooling device 10 is given where the container arrangement 30 is in the closed position II. Accordingly, the carrier tray 32 passes to the closed position II as it fills the inner gap 312 of the control unit housing 31. This closed position II is the operation position of the cooling device 10 under normal conditions, and the control unit 20 is protected from external factors. For providing this, the second connection element 321 moves on the first connection element 311 and fills the inner gap 312. In order to be able to keep the carrier tray 32 in the closed position II, at least one first lock element 313 is positioned on the control unit housing 31, and at least one second lock element 323 is positioned on the carrier tray 32. The first lock element 313 and the second lock element 323 are associated with each other in the closed position II, and delimit the movement of the carrier tray 32. For this reason, in a possible embodiment of the present invention, the first lock element 313 is a hole form provided on the carrier tray 32. The second lock element 323 is a protrusion formed in a manner placed to the first lock element 313 which is in hole form. Thus, the desired locking can be realized at the closed position II.

At least one handle portion 322 is positioned on the carrier tray 32. The handle portion 322 is essentially held by the user, and enables displacement of the carrier tray 32 between the open position I and the closed position II. By means of this, the reachability of the container arrangement 30 is increased. In a possible embodiment, the handle portion 322 is provided at a front wall which is in a perpendicular plane with respect to the outer wall surface 12 of the body 11.

By means of all these embodiments, the requirement of operation at the top part of the cooling device 10 for servicing is eliminated. The assembly of the control unit 20 onto the cooling device 10 can be facilitated by means of the container arrangement 30, and repair and maintenance services in case of failures are facilitated. Additionally, as the control unit 20 is positioned on the outer wall surface 12 of the cooling device 10, the wetness risks are also prevented.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
