Description

A COOLING DEVICE COMPRISING A PIPE RETAINER
The present invention relates to a cooling device that comprises a retainer for holding the circulation pipes.
In cooling devices, the circulation pipes wherein the refrigerant used in the refrigeration cycle is circulated extend between the inner wall and the outer wall so as to be invisible to the user. There may be differences among the temperatures of the refrigerant in the circulation pipes, the outer environment and the cabinet wherein the refrigeration process is realized. In this case, fastening the circulation pipes so as to contact the inner wall or the outer wall in order to fix or support them, causes condensation on the inner surface of the cabinet or the outer surface of the cooling device due to temperature difference. Condensation visible inside the cabinet not only causes user dissatisfaction but also causes the foodstuffs to be spoiled quickly. The state of the art pipe retainers damage the outer wall and the inner wall having a relatively thin structure.
In the state of the art Patent Application No. WO2012089475, a cooling device is disclosed, comprising a retainer that enables the circulation pipes to be fastened between the inner wall and the outer wall.
The aim of the present invention is the realization of a cooling device having a retainer that serves to hold the circulation pipes without damaging the body of the cooling device and without causing condensation on the inner wall and the outer wall.
The cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a retainer with a spiral spring shaped body, that is disposed between the inner wall and the outer wall and that enables the circulation pipes to be supported. Therefore, the retainer is enabled to hold the circulation pipes between the inner wall and the outer wall without damaging the inner wall and the outer wall. By means of its spiral spring-shaped body, the surface area of the retainer contacting the inner wall and the outer wall is increased and the pressure applied by the retainer onto the inner wall and the outer wall is decreased.
In an embodiment of the present invention, the retainer is produced from resilient material. Thus, the retainer absorbs shocks that may come from outside and prevents the circulation pipes from being damaged. Moreover, the retainer is prevented from being broken/cracked when a load acts onto the cooling device from inside or outside.
In an embodiment of the present invention, the retainer comprises at least one housing having an inlet port that enables the circulation pipes to be placed therein in order to hold the circulation pipes. The circulation pipes pass through the inlet port and are fixed by seating into the housing and are prevented from moving.
In an embodiment of the present invention, the housing is almost circular and the circulation pipes are surrounded all around. Holding the circulation pipes that generally have circular cross-sections by means of a retainer having the same structure, provides a more stabilized supporting.
In an embodiment of the present invention, the width of the inlet port is narrower than the diameter of the circulation pipe so that the circulation pipes seated into the housing are not dislodged. A mild force is applied so that the circulation pipes pass through the inlet port while being fastened to the housing. By means of the inlet port that enables the circulation pipes to be snap-fittingly seated into the housing, the circulation pipes are prevented from dislodging.
In an embodiment of the present invention, the retainer is produced from plastic material. Since the thermal conductivity coefficient of plastic material is low, there is no heat transfer between the circulation pipes and the inner and outer walls.
By means of the present invention, the circulation pipes are enabled to be placed without contacting the inner wall or the outer wall and condensation, also called sweating, on the outer surface of the cooling device or inside the cabinet is prevented. Moreover, the retainer is prevented from damaging the inner wall or the outer wall.
The cooling device realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
Figure 1 – is the top schematic view of a cooling device.
Figure 2 – is the perspective view of the retainer in an embodiment of the present invention.
Figure 3 – is the perspective view of the circulation pipe and the retainer in the assembled state.
The elements illustrated in the figures are numbered as follows:
1. Cooling device
2. Cabinet
3. Inner wall
4. Outer wall
5. Circulation pipe
6. Retainer
7. Body
8. Housing
9. Inlet port
The cooling device (1) comprises a cabinet (2) wherein the refrigeration process is realized, an inner wall (3) surrounding the cabinet (2), an outer wall (4) with a heat insulation material provided between the inner wall (3) and itself, at least one circulation pipe (5) that is disposed between the inner wall (3) and the outer wall (4), and at least one retainer (6) that enables the circulation pipes (5) to be fastened between the inner wall (3) and the outer wall (4).
By means of the retainer (6) provided in the cooling device (1), the circulation pipes (5) are supported without contacting the inner wall (3) and the outer wall (4).
In the cooling device (1) of the present invention, the retainer (6) comprises a spiral spring-shaped body (7). By means of the spiral spring shape of the retainer (6) body (7), a curved surface is enabled to contact the inner wall (3) and the outer wall (4) and thus the retainer (6) is prevented from damaging the inner wall (3) and the outer wall (4).
In an embodiment of the present invention, the retainer (6) is produced from resilient material. By means of the flexible structure of the retainer (6), the retainer (6) is prevented from damaging the cooling device (1) when a pressure is applied onto the outer wall (4); moreover, the circulation pipes (5) are prevented from being damaged due to shocks thanks to the retainer (6) that absorbs vibrations.
In an embodiment of the present invention, the retainer (6) comprises at least one housing (8) having an inlet port (9) that enables the circulation pipes (5) to be placed therein. The circulation pipes (5) are seated into the housing (8) by passing through the inlet port (9).
In an embodiment of the present invention, the housing (8) is partially shaped as a ring. With the shape of the housing (8) matching the shape of the circulation pipes (5), the circulation pipes (5) are enabled to be supported in a balanced manner in the retainer (6).
In an embodiment of the present invention, the width of the inlet port (9) is narrower than the diameter of the circulation pipes (5). By means of this embodiment, the circulation pipes (5) are prevented from dislodging without applying any force after being fastened to the retainer (6).
In an embodiment of the present invention, the cooling device (1) comprises the retainer (6) produced from plastic. Thus, the heat insulation is provided between the refrigerant flowing through the circulation pipes (5) and the inner wall (3) and the outer wall (4).
By means of the retainer (6) used in the cooling device (1) of the present invention, sweating problem is solved by preventing the circulation pipes (5) from contacting the inner wall (3) and the outer wall (4) under any circumstances, moreover by means of the spiral spring-shaped body (7), the retainer (6) is prevented from damaging the inner wall (3) and the outer wall (4).
