Description

Refrigerating appliance and method for producing the same

The present invention relates to a refrigeration device with a refrigerated goods container, and to a method for producing a refrigeration device. In refrigerators, a refrigerant is typically conducted in a closed circuit. In this case, the refrigerant is first compressed by a compressor, condensed in a first heat exchanger with heat dissipation, expanded with a throttle and evaporated in a second heat exchanger at low temperature while absorbing heat. As a second heat exchanger tube evaporator are known which can be arranged in a refrigerated goods. During operation, the tube evaporator receives heat through the refrigerated goods container, which thus leads to cooling of the space inside the refrigerated goods container.

Pipe evaporators are often formed as a coil, which meanders over a certain area to achieve favorable heat exchange conditions. However, these coils can be easily twisted or moved by the refrigerated goods in the refrigerated goods and thus be exposed to greater mechanical loads that can lead to a defect in extreme cases. It is therefore an object of the present invention to provide a refrigerator, the tube evaporator can be stabilized in a simple manner.

Under a refrigeration device is in particular a household refrigeration appliance understood, ie a refrigeration appliance for household management in households or possibly in the

Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer or a Kühlgefrierkombination.

The object is achieved by a refrigeration device according to claim 1.

It is a refrigerator, provided with a refrigerated goods, in which a

Pipe evaporator is arranged with a plurality of pipe sections, wherein at least one of the pipe sections passed through a wall of the refrigerated goods is, wherein the guided through the wall of the refrigerated goods container pipe section and at least one further pipe section are fixed together by means of a holding device.

Thus, it can be ensured that the pipe sections are not rotated or shifted by refrigerated goods and are thus exposed to high mechanical loads. Further, according to this embodiment, a tube evaporator can be used, the tube sections are rotated against each other during a phase of production, and which are fixed to each other only after this phase. The pipe sections can be fixed in particular in one plane.

The mutually fixed pipe sections can each be straight and be arranged substantially parallel to each other in the refrigerated goods.

The holding device can be arranged on the side of the tube evaporator facing the wall of the refrigerated goods container. Thus it is sufficient if the

Pipe evaporator is attached to the refrigerated goods only on the opposite side by means of clips or the like.

The holding device can be fastened by means of a latching connection or a clip connection to the tube evaporator. Thus, a simple mounting of the holding device is possible.

The holding device may have, for example, at least two, preferably at least three hooks which fix the pipe sections. Furthermore, the holding device may have at least one bearing surface on which rest the pipe sections. Thus, a reliable fixation of the pipe sections is possible.

The pipe sections can, for example, with the exception of the outside to the tube evaporator arranged pipe sections, be connected to each other by a plurality of transverse to the pipe sections arranged transverse ribs. Thus, the outer pipe sections and the middle pipe sections can be rotated against each other, which can be advantageous for the production. The holding device may have at least one retaining lug, which is arranged between two of the transverse ribs and fixes one of the pipe sections. Thus, a better fixation of the pipe sections and the holding device can be achieved.

The holding device may have a bottom wall, in which at least one drain hole for discharging condensation water is provided. Thus, a relatively large-scale holding device can be provided, which allows a stable fixation and is reliably dissipated in the condensation.

The holding device can be dimensioned such that it fixes exactly two or exactly three pipe sections together. Thus, the holding device can be made so compact that it can be mounted with one hand.

It may be provided preferably two of the holding devices. In particular, a holding device can be provided on each side of the tube evaporator, resulting in a particularly stable fixation of the tube sections.

The holding device can extend over the entire width of the tube evaporator. With this embodiment, all pipe sections can be fixed with only one holding device. In this case, the holding device may be, for example, a bar designed as an angle profile or U-profile. The strip can be a lower strip portion on which the pipe sections rest, as well as the lower strip section

have opposite retaining projections, wherein the pipe sections between the lower strip portion and the retaining projections are fixed. Between the holding device and the wall, a spacer may be arranged. This spacer ensures that the holding device can not be moved backwards in the direction of the wall and arranged there

Temperature sensor or the like damaged. A method for producing a refrigeration device with a refrigerated goods container, in which a tube evaporator is arranged with a plurality of pipe sections, wherein at least one of the pipe sections is guided through a wall of the refrigerated goods, has the following step: fixing the through the wall of the refrigerated goods guided pipe section and at least one further pipe section by means of a holding device.

In this case, the pipe sections can be determined by the fixing by means of the holding device in a plane.

The method may further comprise the steps of:

- In particular flat application of at least a portion of the pipe sections to an inner wall of the refrigerated goods, not all pipe sections of the

Pipe evaporator are in the same plane;

- Foaming the refrigerated goods container with a heat-insulating material;

- After foaming, set the pipe sections of the tube evaporator in a plane.

This makes it possible to use a tube evaporator which is so flexible that it can be pressed against the outer wall by a foaming core or the like during the foaming process, wherein a part of the tube sections is already guided through the outer wall of the refrigerated goods container. Thus, the tube evaporator arranged in the refrigerated goods container can be completely welded before foaming, and at the same time it can be ensured that the walls of the refrigerated goods container are not pressed in by the foam pressure.

1 shows a perspective view of a tube evaporator 130

wrapped refrigerated goods container 110 of a refrigeration device 100. The refrigerated goods container 110 has substantially the shape of an open towards the front and towards the rear

truncated cuboid having a top wall 120, bottom walls 122 and 124, left and right side walls 126 and 128, and a stepped rear wall defining an interior 160. The refrigerated goods container 1 10 may be made for example of plastic. The open front side of the refrigerated goods container 1 10 is surrounded by a frame 140. In each case two receiving latches 150 are provided in the side walls, with which dividing walls for vertical subdivision of the refrigerated goods container can be accommodated.

The refrigerated goods container 110 is wrapped with a first tube evaporator 130, which is arranged outside the refrigerated goods container 110. In operation, the first

Pipe evaporator 130 is charged with a refrigerant which evaporates by absorbing heat. In this case, the first tube evaporator 130 through the refrigerated goods 110 through heat, which thus leads to a cooling of the interior of the

Refrigerated goods 110 leads. Within the refrigerated goods container 1 10 and in the present example in the ceiling area, so near the ceiling wall 120, a second tube evaporator 200 is provided in the form of a tiered storage, which is shown in Fig. 2 in a perspective view. The second tube evaporator 200 comprises an evaporator tube 210 and a multiplicity of transverse ribs 220. The evaporator tube 210 comprises, for example, ten straight tube sections 210a, two of which are connected at their ends by bent tube sections 210b, so that the evaporator tube 210 extends meandering in a plane , The transverse ribs 220 are formed, for example, as straight pieces of wire and are arranged on the two sides of the evaporator tube 210 and attached thereto, for example, by soldering or the like. In this case, the transverse ribs 220 extend between the second and the penultimate straight pipe section 210a, so that the distance between the two pipe ends 230 is easily changed by compression or extension and the two pipe ends 230 can be easily rotated out of the plane defined by the transverse ribs 220. By the transverse ribs 220, the pipe sections are held together, so that the evaporator tube 210 is provided with a certain rigidity. On the other hand, they improve the heat exchange properties of the evaporator tube 210.

The two outer straight pipe sections 210a are through the rear wall of the

Refrigerated goods container 1 10 out. These two outer straight pipe sections 210a serve as a supply and discharge of the tube evaporator 200th

Due to the provision of the second tube evaporator 200, a more uniform temperature distribution within the refrigerated goods container 110 is achieved, which leads to a reduced standard energy consumption of the refrigeration device. In this case, the first tube evaporator 130 and the second tube evaporator 200 can be connected in series with each other in terms of flow. Thus, both tube evaporators 130, 200 are operated via only one cooling circuit and no further compressors, valves or the like need be provided for the additional evaporator. On the input side, the tube evaporator 130, 200 may be connected to a throttle valve, not shown, and on the output side to a compressor, for example a linear compressor (not shown). FIG. 3 shows a perspective sectional view through a refrigeration device 100, the section extending in a direction perpendicular to the first tube evaporator 130. In this refrigeration appliance 100, the second tube evaporator 200 is fastened to the ceiling wall 120 in the front region of the refrigerated goods container 110 by means of a strip 300 and latching connections, eg clips 170.

As can be seen in FIGS. 3 and 4, the second evaporator tube 210 is inserted into the strip 300, which in turn is inserted into the clips 170 provided in the ceiling region. The advantage of this arrangement is that the second evaporator tube 210 is held at a predetermined distance from the ceiling wall 120. Thus, a better cooling circulation in the refrigeration device 100 can be ensured.

Fig. 4 further shows that three of the straight pipe sections 210a by a

Holding device 500 are fixed to each other. More specifically, the first, second, and third straight pipe portions 210a of the tube evaporator 200, counted from the left, are fixed to each other by the holder 500.

As stated above, the straight pipe sections 210a except for the outermost two straight pipe sections 210a are fixed to each other by the transverse ribs 220 and provided with rigidity. However, since the transverse ribs 220 do not extend to the two outer straight pipe sections 210a, the two outer pipe sections 210 are rotatable relative to the middle straight pipe sections 210a. More specifically, the two outer straight pipe sections 210a may be rotated from the plane defined by the central straight pipe sections 210a, and the middle straight pipe sections 210a may be compressed by the tube evaporator 200 in-plane onto the outer straight pipe sections 210a be moved to or away from them, or be moved in the direction of the straight pipe sections. When installed, in particular, there is the risk that the middle straight pipe sections 210a are pushed up by chilled goods, which leads to an increased mechanical load on the pipe evaporator 200. Furthermore, a temperature sensor 400 for detecting the interior temperature can be arranged in the rear area of the interior. When moving the arranged in the region of this temperature sensor 400

Tube sections 210a, 210b of the tube evaporator 200 to the rear there is a risk the tube evaporator 200 abuts against the temperature sensor 400 and damages it. By fixing with the holding device 500, the pipe sections 210a can be fixed to each other, so that a fixed, predefined position of the

Pipe evaporator 200 is secured. At the same time, the tube evaporator 200 also protects the temperature sensor 400 from being damaged by the frozen food.

FIGS. 5a to 5e show different views of the holding device 500. Fig. 5a shows a perspective view of the holding device 500. Fig. 5b shows a bottom view of the holding device 500. Fig. 5c shows a side view of the holding device 500. Fig. 5d shows a plan view of the Holding device 500. FIG. 5 e shows a front view of the holding device 500.

The holding device 500 comprises a bottom wall 510, three hooks 520a, 520b and 520c and a side wall 530. The bottom wall 510 is substantially rectangular in shape, with rounded corners, and has on the left side in FIGS. 5b to 5d a recess. The side wall 530 extends from the edges of this recess around the bottom wall 510 so that a cup-shaped shape results through the bottom wall 510 and the side wall 530. The side wall 530 serves, inter alia, as a support for the tube evaporator 200th

On the bottom wall 510 three hooks 520 are arranged, each one

Foot portion 522 and an arm portion 524 have. The foot portion 522 extends substantially perpendicularly from the bottom wall 530, and the arm portion 524 extends from the foot portion 522 substantially in the right leg

Arm portions 524 are arranged in the longitudinal direction of the holding device 500, wherein its free end to the left in Figs. 5b to 5d points. The arm portions 524 thus extend substantially parallel to the bottom wall 510. The width of the hooks 520b and 520c and in particular their arm portions 524 is such that they can easily be guided by the transverse ribs 220. The hook 520a can be made wider. As can be clearly seen in particular in FIG. 5 d, the hooks 520 may be formed in each case from two plate-shaped elements 528 arranged in parallel, which are connected to one another by web elements 529 arranged therebetween.

In the region of the recess described above, two web elements 540 are arranged, which extend from the bottom wall 510 in the same plane to the front. Since these web elements 540 are substantially thinner than the bottom wall 510, they can be rotated with relatively little effort out of the plane of the bottom wall 510. On their front side, the web elements 540 each have an upwardly extending wall 542, which is substantially flush with the side wall 530 but extends slightly more upwardly in the vertical direction. Furthermore, in the illustrated example, this wall 542 extends longitudinal ribs 544 in the longitudinal direction of the holding device 500.

The in Figs. 5b to 5d left hook 520a has an end portion 526 which points slightly downward. Together with the web elements 540 this forms

End section 526 thus a clip into which a pipe section 210a can be clipped. Thus, the holding device by means of a latching connection or a

Clip connection are releasably connected to the tube evaporator 200. Of the

Tube section 210a is fixed downwardly from side wall 530, rearwardly from foot section 522 of hook 520a, upwardly from arm section 524 of hook 520a, and forwardly from end section 526 and wall 542 and longitudinal ribs 544, respectively.

On either side of the central hook 520b, transverse ribs 550 extend between the foot portion 522 of the middle hook 520b and the side wall 530. Further, transverse ribs 560 are disposed on the foot portion 522 of the rear hook 520c extending approximately half way between hooks 520c and sidewall 530 extend. As the top of the side wall 530, the transverse ribs 550 and 560 also serve as supports supporting the tube evaporator 200, as will be explained in more detail below. Further, the transverse ribs 550 and 560 increase the inherent rigidity of the fixture 500 and thus increase its stability. Further, retaining lugs 570a are disposed on the side wall 530 in the region of the middle hook 520b on both sides. These retaining lugs 570a extend slightly in height beyond the side wall 530, as can be seen for example in FIG. 5c. The retaining tabs 570 a are spaced from the transverse ribs 550, wherein the spacing of the retaining tabs 570 a in the longitudinal direction of the holding device 500 from

Foot portion 522 of the hook 520b corresponds approximately to the diameter of the evaporator tube 210. Thus, in the fastened state, the evaporator tube 210 is fixed in the region of the middle hook 520b from four sides, downward from the side wall 530, rearward from the foot portion of the hook 520b, upward from the arm portion of the hook 520b, and forward from the retaining tabs 570a.

Also at the rear end of the holding device 500 are on the side wall 530th

Holding lugs 570b arranged. The width of the retaining lugs 570 a and 570 b is such that the retaining lugs between two adjacent transverse ribs 220 of the tube evaporator 200 can be pushed. Preferably, the width of the retaining lugs 570a and 570b may be slightly wider than the distance between two adjacent transverse ribs 220, so that the transverse ribs 220 are elastically slightly pushed apart during insertion of the retaining lugs 570a and 570b, resulting in an additional fixation of the holding device 500 on the tube evaporator 200 leads. In the bottom wall 510 520 drainage holes 580 are provided below the hooks, which allow the flow of condensate. Furthermore, these drainage holes 580 provide an advantageous configuration for the manufacture of the fixture 500 in FIG

Injection molding. The holding device 500 may be made of plastic, for example.

The Fign. Figures 6a and 6b illustrate how the outer three straight pipe sections 210a are fixed to the fixture 500. For this purpose, first the holding device 500 is brought with the hook 520 upwards under the tube evaporator 200. Next, the retainer 500 is moved upwardly, passing the hooks 520b and 520c through the transverse ribs 220 in the region of the second and third and third and fourth straight pipe sections 210a, respectively. Since no transverse ribs are arranged between the first and second pipe sections 210a, the hook 520a can be freely moved upwards. At the same time, the retaining lugs 570a and 570b become between two adjacent ones, respectively Transverse ribs 220 out, which may be slightly pushed apart. Next, as indicated by the arrow in FIG. 6b, the holding device 500 is moved to the left, that is, toward the outermost straight tube section 210a. At this time, the web members 540 are slightly pushed down and the arm portion 524 of the first hook 520a is slightly pushed up, and the outermost pipe portion 210a is clipped.

At the same time, the arm portions 524 of the hooks 520a, 520b, 520c are respectively slid over the first, second and third straight pipe sections 210a. Thus, the first to third pipe sections 210a are securely fixed upwardly through the hooks 520, downwardly through the supportive sidewall 530 and the transverse ribs 550, 560, rearwardly through the legs 522 of the hooks 520, and forward through the hooks 520 Holding tabs 570 a as well as formed by the wall 524 and the end portion 526 clips. The thus fixed pipe sections 210a can thus not be rotated against each other. Furthermore, the tube evaporator is thus stiffened.

It should be noted that the above-described method of fixing the pipe sections 210 can advantageously be performed with one hand.

The above-described method for fixing the pipe sections 210 may be the last step in a method for manufacturing a refrigeration device, which will be described below with reference to FIGS. 7 to 9.

In a first step of the manufacturing process, the clips 170 of the

Outside of the refrigerated goods container 1 10 placed in indentations in the top wall 120 of the refrigerated goods container 1 10, wherein the legs of the clips 170 are guided through through holes in the top wall 120 of the refrigerated goods 110, after which the clips 170 can be secured, for example, with tape. The situation shown in FIG. 7 results in that the clips 170 protrude freely from the ceiling wall 120 into the interior 160 of the refrigerated goods container 110.

In the next step, the second tube evaporator 200 is pushed into the interior 160 of the refrigerated goods 110, the tube ends 230 of the second tube evaporator 200 are guided through through holes in the rear wall of the refrigerated goods 1 1, and the second tube evaporator 200 is at two of its bent pipe sections 210 b with the Clips 170 clipped to the ceiling wall 120. Next is the refrigerated goods container 110 wrapped with the first tube evaporator 130. After that, the first one

Pipe evaporator 130 and the second tube evaporator 200 are joined together by welding or the like. It should be noted that the first and second tube evaporators 130 and 200 may also be mounted in reverse order.

The refrigerated goods 110 is now pushed into a not-shown outer housing with a device outer wall and fixed it. Further, in the inner space 160 of the refrigerated goods container 110, a foaming core made of aluminum or the like is placed. This foaming core is used for stabilization and is dimensioned such that the underside of the second tube evaporator 200 rests on the top of the foaming core. At this time, the middle pipe portions 210a stiffened by the transverse ribs 220 are pushed up, and the upper end of the foaming core is disposed between the outermost straight pipe portions 210a. In other words, in this state, the outermost straight pipe sections 210a extend through a plane other than the central pipe sections 210a, which are parallel to the ceiling wall 120 as shown in FIG. 8. More specifically, in this state, the outer straight pipe sections 210a extend obliquely from the two through holes in the rear wall to the clips 170 arranged in the front region of the refrigerated goods container. Furthermore, the foaming core can support the rear wall 620 and the side walls of the refrigerated goods container 1 10 from the inside.

Thus, it is also apparent why the transverse ribs 220 do not extend over all the straight pipe sections 210a. If this were the case, then the middle straight pipe sections 210a could not be pressed against the ceiling wall 120 with the foaming core.

In the next step, the space between the refrigerated goods 1 10 and the device outer wall is filled with a heat-insulating material. Since the second tube evaporator 200 fits tightly against the top wall 120, it stabilizes on the one hand the top wall 120 and on the other hand passes the pressure resulting from the foaming on the top wall 120 to the foaming core, so that a deformation or

Denting the ceiling wall 120 can be prevented. In the figures are off illustrative reasons, neither the device outer wall nor the heat-insulating foam shown.

After foaming, the second tube evaporator 200 is released from the clips 170 and slightly lowered at its front, as shown in Fig. 9. The straight pipe sections 210a are brought back into a plane. Thereafter, the strip 300 is plugged into the second tube evaporator 200. Finally, the strip 300 is clipped or fixed to the clips 170. This results in the state shown in Fig. 3. Thus, the second tube evaporator 200 is no longer close to the ceiling wall 120, but is spaced therefrom, so that there is an advantageous refrigeration circulation within the refrigerated goods 110.

In this state, the tube evaporator 200 is forward over the bar 300 and the clips 170 are attached to the ceiling wall. Further, the outer straight

Pipe sections 210a fixed by means of the passage through the rear wall of the cooling tank. However, the middle straight pipe sections 210a swing freely and thus can easily be displaced or twisted by refrigerated goods. Therefore, in a last step, the outer three straight pipe sections 210a are fixed to each other by the holding device 500 in the manner described above. In the ready-to-use state, the refrigerated goods container 110 can be surrounded on five sides by the device outer wall and can be closed to the front with a door.

With the above-described method, during the foaming operation, the second tube evaporator 200 closely abuts against the ceiling wall 120 and stabilizes it, so that it can be prevented from being deformed due to the foam pressure and dented inward. Furthermore, all soldering operations on the second tube evaporator 200 can already be carried out by the foaming. In particular, that can

Output side end of the first tube evaporator 130 are soldered to the input-side end of the second tube evaporator 200 and then tested for leaks before foaming. If, however, the second tube evaporator 200 is used only after foaming, then an additional step for testing the tightness is necessary. Previously, an embodiment has been described in which the outer pipe sections 210 a on the left side in the interior 160 of the refrigerated goods container 1 10 with a

Holding device 500 are held together, but it is also possible to fix the outer pipe sections 210a on the left and on the right side each with a holding device to each other. Thus, a better fixation of

Tube sections 210a can be achieved.

Alternatively, it is also possible to provide a holding device 1000, which extends over the entire width of the tube evaporator 200. Such a holding device 1000 is shown by way of example in FIG. 10. The holding device 1000 illustrated in FIG. 10 has a base strip 1010 and six hooks 1020 fastened thereto. More specifically, in each case a hook 1020 is provided in the end regions of the base strip 1010, wherein these hooks 1020 fix the two outermost straight pipe sections. Further, in the region of, counted from the outside, in each case third straight pipe sections 210a each two hooks 1020 are provided, which are spaced from each other. There are thus fixed with this holding device 1000, four different straight pipe sections 210a to each other. This holding device 1000 is also fixed by being brought under the tube evaporator 200, then moved upwards and finally by moving to the left the tube sections 210a are fixed with the hooks 1020. However, the embodiment described above is advantageous in that the holding devices 500 can be used with one hand and also have a lower cost of materials.

11 shows a further alternative embodiment of a holding device 1 100. This holding device 1100 is designed as a strip and has a base strip 11 10 and a side strip 1120, which are arranged at right angles to each other and a

Angular profile result. In this case, the side bar 1 120 does not extend over the entire length of the base strip 1110, but at least over a large central area thereof. Alternatively, the holding device 1 10 may be formed as a U-profile. At one end of the base bar 11 10 this U-shaped bent, resulting in a U-shaped hook 1130 results. At the other end, a recess is provided in the side rail 1 120, in which a pipe section 210a can be accommodated. Further, locking lugs 1 140 are provided at this end. Also on the U-shaped Hooks 1130 can be provided here not shown locking lugs. The holding device 1100 is fixed by engaging the pipe sections with these locking lugs.

Further, extending from the side rail 1120 retaining projections 1150 forward, which fix the middle straight pipe sections 210a and ensure that they can not be bent upwards.

Further, 1 120 rubber bumpers 1160 are disposed on the outer straight pipe sections 210a between the rear wall and the side rail. These rubber bumpers 1160 serve as spacers and ensure that the holding device 1 100 can not be pushed backwards and come into contact with the temperature sensor 400.
