Description

Descriptive Report of the Invention Patent for REFRIGERATOR.

Technical Field [001] The present invention relates to a refrigerator with a cooling compartment for products to be refrigerated, with a housing that at least partially integrates the cooling compartment, with an access door to the provided cooling compartment. in an opening of the housing and movable in relation to the housing, and with a door fixation, provided between the door and the housing, which presents an opening assembly with a movable lever to move the door, especially around a movable axis horizontal from a closed position to an open position.

State of the Art [002] To make the refrigeration compartment of a refrigerator accessible, closed by a door, doors are known with the most diverse door fixings that, through an opening set, allow the door to move from a closed position to a position open. Thus, for example, from document DE 140 1 078 A1 it became known to fix the door that movably holds a door in the housing through a mobile assembly. For this purpose, two movable levers are provided laterally on the door, so that with the movement of these levers you can open the door vertically upwards. Although, a door fixation of this nature can create unobstructed access to the refrigerator's refrigeration compartment, it was evidenced that mobile sets, in addition to the larger static and disadvantageous preconditions for the mobility mechanism, are only restricted because the doors are moved with this mechanism it can react sensitively to stress forces conditioned by movement. Lon

2/14 g downtime periods that are especially required in industrial use of refrigerators, cannot be guaranteed with these mobile mechanisms.

[003] For this reason, door fasteners with alternative opening assemblies (US 4 369 632), which have, for example, turning sets with vertical projection turning axes, have become known. Although opposed to door fasteners with tilting sets, these door fasteners can guarantee a long durability, because neither the components of the opening set nor the doors are exposed compared to intense demands on opening, but it is a disadvantage in these door fastenings that with the doors open, they stand out from the refrigerator and thereby restrict the refrigerator's movement area. Barrier-free access cannot therefore be guaranteed by these door fastenings, which implies comfort disadvantages.

Description of the Invention [004] Therefore, the present invention aims to shape, in such a way, a refrigerator with a movable door of the kind initially mentioned that in a simple constructive way it can be ensured both a high resistance of the fixation of the door, as well as a barrier-free access to the cooling compartment.

[005] The invention solves this task, due to the fact that the fixing of the door has a support connected with the tilting lever, especially sequential to the tilting lever and that has, at least, a part of another set of opening fixing the door for moving the door from a closed position to another open position in front of the open position of the other opening set.

[006] When the door fixation has another opening set to move the door from the closed position to another open position, opposite the open position of the other opening set, en

3/14 So, according to the invention, it may be possible to provide a fixed tilting set simply because, according to the users' habit, a uniform use of the two access alternatives will be adjusted in the middle, so that without special additional construction measures, a tilting set may also be provided. In particular, however, the durability can be increased when the door fixture has a support connected with the rocker lever and which supports at least a part of another door fixture opening assembly. The demands of the door resulting from the tilting movement can thus be transferred to the support, which can improve the possibility of loading the door and, especially, therefore, the durability of the door fastening. Simple construction conditions result when the support is sequential to the rocker lever. Therefore, contrary to the state of the art, the invention can not only guarantee greater durability of the refrigerator, but also an alternative access, that is, among other factors, also a barrier-free access to the refrigerator.

[007] Especially the door and / or the other opening set can be relieved of forces resulting from the tilting movement when the door fixation has a support and the support is in such a way, placed in front of the door that in the movement of the door around of the tilting axle, the support, through a support provides a removal of force on the tilting lever. Deformation forces conditioned to the tilting movement can thus be removed in a simple way, which can reduce the predictions in the construction field for both the door and the other opening assembly. For this reason, also in view of the state of the art, doors with glassy surfaces can be envisaged, that is, tilting glass doors, which can be especially advantageous for the comfort of use, because this way before opening the door, the products inside comparPetition 870190092148, of 09/16/2019, p. 7/25

4/14 cooling device can be seen. Then, with the support, the security of fixing the door can be increased by reducing the danger of the door breaking, that is, fixing the door. Therefore, the support can be arranged in such a way in front of the door that in the tilting movement of the door an energy connection is created in the direction of the other opening set, so that the tilted door can be relieved in an improved manner. The support preferably serves, at least, for a partial support of the tilted door. Of course, the rocker lever should not always be seen as a straight lever, but it can occupy a joint form with the support, which can express the most diverse situations. [008] If the support has a support frame, then not only can a construction be created that can receive load for the additional opening mechanism, but, advantageously, this frame can also be used as support that can receive a load. In addition, the frame, for example, can alleviate the tilted door on all sides, which can especially enable comparatively high security in relation to damage to doors and glass surfaces, ie glass doors. Simple construction conditions result when the rocker lever and the support are a unit built together.

[009] Simple construction conditions for a sliding conduction result when the support has a horizontal conduction of the sliding conduction, because in this way the support, in construction, can be used for the other opening set conformed as sliding conduction.

[0010] If another opening assembly is formed as a rotating assembly, comprising a swing bearing attached to the support that has a swing axis inclined in the direction of the tilting axis, especially of normal projection, then, regardless of the construction of the

Petition 870190092148, of 16/09/2019, p. 8/25

5/14 door, a cost-effective suspension for the door may be created.

[0011] In order to suppress the uncontrolled swing of the tilted door, it can be foreseen that the support mounted on the side of the door facing the cooling compartment limits the swing region of the door. This way, in a simple way, the security of fixing the door can be improved, because with the door tilted, this slope on the support with backrest limitation, and in this way, it cannot perform unwanted rotating movements during a door swing.

[0012] To increase the rigidity of the housing in the face of tilting stresses, between the housing wall protruding from the housing cover and the housing cover, a support bar is provided with the action of joining forces.

[0013] If the housing with a support structure limits the structural supports and the support connections, at least partially a cycle of ambient air subject to the temperature in the refrigeration compartment, then the dimensions of the refrigerator can advantageously be kept low extension, because the conductive assemblies provided for the ambient air can be placed between the cooling compartment and the external side of the housing, that is, the housing can be used to form this assembly. Advantageous viewing conditions can be created when the ambient air cycle, at least in the region of the housing and door coupling, has openings for holding the door with cooling air in the direction of the cooling compartment, as this way , simply, condensed water on the door can be avoided.

[0014] Depending on the load applied and to be removed, the two tilting levers can be provided reciprocally apart

Petition 870190092148, of 16/09/2019, p. 9/25

6/14 and specially planned in parallel, which act together in the door frame and which, through an individual swivel bearing, are attached to the housing roof. In addition, the constructive dimensions of the refrigerator may be reduced, since, in the intermediate region of the two tilting levers, means are provided, for example, for the compressor and / or the condenser, for the refrigerant cycle of the ambient air cycle.

Forms for Carrying Out the Invention [0030] A refrigerator shown, for example, in figure 1, has a cooling compartment 1 for storing products to be refrigerated and which are not represented in more detail. The cooling compartment 1 will be partially enclosed by a housing 2. In an opening 3 of the housing 2, a door 4 with two wings 5 and 6 is provided, and through a door fixation 7, the door 4 is attached to the housing 2. The fixing of the door 7 allows the door to be moved so that in this way access to the products can be created in the refrigeration compartment 1. The door movement of this type will first be made possible with the aid of an opening set 8. This opening set 8 creates a possibility of moving door 4 around a horizontal tilting axis 9 from a closed position 10 to an open position 11, the two positions 10 and 11 being shown in figure 2. Position 11 shown with a dotted line in figure 2 it effectively represented a final position and other tilted open positions can be imagined, but for visualization reasons they are not most rated. This open position 11 stands out for the fact that door 4 does not protrude into the users' movement compartment in front of the refrigerator. It happens that port 4

8/14 is essentially on the cover 12 of the housing 2. As the door 4 has transparent regions and is therefore partially permeable to light, the products stored in the cooling compartment 1 can be seen from the outside. In addition, the door can predominantly, that is, be made completely transparent or also impermeable to light. It is disadvantageous in the removal of refrigerated products that by a tilting movement of the door 4, a comparatively large opening of the refrigerator is necessary in order to be able to remove the goods from the refrigeration compartment 1. In order that an improved withdrawal can be created, adjusted to position of the refrigerated products in the cooling compartment 1, it is proposed, according to the invention, that the fixing of the door 7 has a support 15, sequentially to the tilting lever 14 of the opening set 8, which has at least parts 16 another set of opening for fixing the door 7, configured as a swivel set 17, to move the door 4 from the closed position 10 to another open position 18 in relation to the open position 11 of the tilting set 8. The open position 18 can be seen, especially in figure 3. The ease of operating the refrigerator will therefore be increased because the rotating assembly 17 creates a sec unda possibility of movement of the door 4, that is, the wings of the door and 6, around a turning axis 19 of essentially vertical projection.

[0031] According to figures 4 and 5, the fixing of the door 7 is shown in more detail. In this way, the tilting assembly 8, the welded support 15 is sequential and in this case the rotating assembly 17. The opening assembly 8 consists of a tilting bearing 20 and a tilting lever 14 which can be moved around a tilting axis. 9 of the tilting bearing 20. The support 15 protrudes vertically from the tilting lever 14 in order to allow it to act

Petition 870190092148, of 16/09/2019, p. 12/25

9/14 on this support 15 support means 21, for example, a pressure-tension spring to facilitate tilting movement. The swivel assembly 17 is attached to the support 15, with part 16 of the swivel assembly 17 surrounding the support 15 and protruding from it, so that the pin 19 'that forms a vertical axis of rotation 19 can penetrate the other parts of the turning set 17, which are attached to port 4 not shown. In the region of the opening of the housing 3, the support 15 may be surrounded by an insulation not shown in more detail, so that in this way the thermal conductivity of the support 15 is reduced.

[0032] The support 15 forms a support frame 15 'that projects in parallel with the lateral edges of the door 4, which can be better seen in figure 5. To relieve the door, as well as, the other set of the support 15 is mounted in such a way in front of the door 4 that when the door 4 moves around the tilting axis 9, the support frame 15 'of the support 15 serves as support 22 for support at least partially of the door 4 tilted. This can also be seen especially in figure 2. The support frame 15 ', arranged behind the door 4, is rotated together with the door 4 and can relieve the door with its support 22, at least in the marginal section. This marginal clearance may be at the top of the door and / or at the bottom of the door. It is also possible to imagine that the sides of the door are relieved, which can occur, for example, in the case of a flexion of the door. In this way, the support 15 can enable an especially good force removal on the rocker lever 14, which creates a fixed and secure door fixation 7. Advantageously, the rocker lever 14 constitutes a joint component with the support 15, and, in addition, it can be imagined to completely form the support 15 and the rocker lever 14.

[0033] In particular, the security of the

Petition 870190092148, of 16/09/2019, p. 13/25

10/14 refrigerator control, when the support 15 provided for the side of the door facing the cooling compartment 1, with its support 22 limit the pivoting area of the door 4, which can be seen especially from figures 2 and 3. The support 22 is so arranged on the support frame 15 'in front of the door that when there is a tilting movement of the door 4, an additional vertical movement cannot occur, that is, the door 4 rotates, that is, the wings of door 5 and 6. It can be imagined that between the support 15 and the door 4 additional means are provided so that a support 22 is created in this way, which, however, does not change the fact that the support 15 serves as support 22. Because during a tilting movement of the door 4, the door 4 on the support 15 eliminates the additional load on the other opening set.

[0034] Between the rear wall of the housing 23, protruding from the housing cover 12, and the housing cover 12, a support bar 24 is provided for joining force.

[0035] In addition, the tilting set 7 features two tilting levers 14 reciprocally spaced and projected in parallel, in whose central region means 25 are provided for the refrigerator's refrigerator cycle. This can represent, for example, a compressor, so that it does not have to be provided at the bottom of the refrigerator, which allows a low position edge of the refrigerator. It is not necessary to mention in addition that all tilting levers 14 of different projection are imaginable.

[0036] The built height of the refrigerator may be reduced, when the housing 2, which has a support structure, between its structural supports 2 'and the transversal connections 2, limits, at least partially, an ambient air cycle 26 which is subjected with temperature in the refrigeration compartment, which can be better seen in figure 6. In order to reduce formation

Petition 870190092148, of 16/09/2019, p. 14/25

11/14 of condensed water, the ambient air cycle 26, in the region of the opening of the housing 3 bordering the door 4, presents a discharge 27 with nozzles 28 for holding the side of the door facing towards the cooling compartment, with application of cooling air. To create a forced churn of the cooling air, the discharge 27 is arranged on the ceiling of the housing 12, and a fan 30, integrated in the bottom of the housing 29, through an inlet 31 introduces at least 26 ambient air cycle , the air expelled from the discharge 27. On the rear wall of the housing 32, the evaporator 33 of the refrigeration cycle is also provided for cooling the cooling air conducted in the ambient air cycle 26. In addition, on the rear wall of the housing 32, through the transverse connections 2, nozzles 28 are provided so that the products stored on the shelves 34, not shown, can be subjected with cooling air. In addition, the refrigerator features for activating the wings of doors 5 and 6 handles 35. A thermal insulation 36 is advantageously mounted on the outside of the housing.

[0037] According to figure 7 an alternative embodiment of an opening set 8 'is shown. Unlike opening set 8 shown in figure 4, this opening set 8 'features a two-arm rocker lever 14' and is attached to the crossbar 24 'via a rocker bearing 20'. By extending the lever 14 of the toggle lever 14 ', support means 21', for example, a pressure-tension spring, act to facilitate the tilting movement of the door 4. Support means 21 'are mounted movable in the housing 2 The support frame 15 ', arranged behind the door 4, will be rotated together with the door 4 and with its support 22 you can relieve the door. In this way, the support 15 can enable an especially good removal of force on the rocker lever 14 '. Especially, with an essential 24 'crossbarPetition 870190092148, of 16/09/2019, p. 15/25

12/14 acting on the outer end of the housing lid 12, as well as on the rear wall of the housing 23 protruding, the rigidity in the region of the refrigerator lid 12 can be improved.

[0038] Another relatively open embodiment of the opening set 8 is shown in figure 8. Compared with the embodiment of figure 2, this opening set 8 ', similar to figure 7, features a two-arm rocker lever 14'. Facing the pressure-tension spring, shown in figure 2, this modality has support means 21 ', which, with the aid of a pulling cable 38, guided on a deflecting roller 37, this cable prestressed with a pulling medium 39, contributes to facilitate the tipping of door 4. Traction weights, motors or also a pressure-tension spring can be used as a traction medium.

[0039] In addition, the other opening set can be configured as sliding conduction 40, which is shown based on figures 9 and 10 as another modality. Advantageously, the support 15 has a horizontal conduction 41 of the slide conduction 40, which reduces the constructive effort. The two wings of the door 5 and 6 move in rolls 42 side by side in the conduction 41, so that, with the displacement of the door wing 5 or 6, the cooling compartment 1 becomes accessible. According to figures 9 and 10, a fragmented view will be shown. However, it is understood, of course, that at the lower end of the door the same conduction may be provided, but not necessarily. The support 15 forms next to the conduction 41 also a support 22, which is positioned on the upper side of the door 4, that is, the wings of the door 5 and 6, which can be recognized according to figure 10. In addition , the support 15 also has a support frame 15 ', into which the wings of the door 5 and 6 can project. This, however, is not only advantageous with regard to a thermal seal, however, the support frame 15 'po

Petition 870190092148, of 16/09/2019, p. 16/25

13/14 will then serve here as support 22, because the side faces of the door can rest there, that is, on the sides bordering the wings of the door 5 and 6, when there is a tilting movement of the door.

[0040] Another modality is shown according to figures 11 and 12, and here the other opening set is formed as a rotating set 17 '. Unlike the swing set 17 of figure 4, the rocker lever 14 is joined with the support 43 through the swing set 17 '. The rocker lever 14 therefore supports a part 16 of the swivel assembly 17 'of the door fixation 7 to move the door 4, with the part 16' protruding from the support 43, so that, in this way, it can penetrate a pin 19 'that forms a turning axis 19 of vertical projection, in the other parts of the rotating assembly 17', whose other parts are provided in the support 43. The support 43 is attached to the door 4 by means of various connection means 44, so that it can remove, in this way, deformation forces resulting from the screed of the door 4 in a simple way, which is advantageous, especially in the case of doors with glass surfaces, i.e. glass door. The support 43 is provided between the rocker lever 14 and the door 4 which can be used advantageously to support the tilted door. The support 43 is so arranged in front of the door 4 that when moving this door 4 around the tilting axis 9, the support 43 can be moved in the direction of the tilting lever 14, so that the support 43 serves as support 22 for rest to the tilted door 4. In this case, however, the support 22 is represented between the support 43 and the rocker lever 14 and not, as shown in figure 2, between the support 15 and the door 4. Figure 11 shows a considerable distance between the support 43 and the rocker lever 14 - the extent of the distance is determined by the possibility of the mobility of the support 43 in the direction of the rocker lever 14. For example, one can imagine overcoming this distance by tolerated strain forces

Petition 870190092148, of 16/09/2019, p. 17/25

14/14 in order to obtain support 22.

[0041] Another modality is shown according to figures 13 and 14. Contrary to the modality of figures 11 and 12, support 43 'is part of door 4, with support 43' supporting the glass face 13 and the parts of the 17 'swivel set. Here, too, the tilting lever 14 can serve as support 22 for the support 43 'when the latter, in the tilting movement of the door 4, moves in the direction of the tilting lever 14. The support 43' is so shaped that rotation is possible. door 4 freely through the rocker lever 14.

[0042] In addition, it is possible to imagine, in a general way, integrating means between the support and the tilting lever, that is, the door before a tilting movement of the door, that instead of a movement of the support, that is, of the then contribute to the formation of rest.
