Description

  The present invention is a refrigeration apparatus having a refrigeration space for articles to be refrigerated, which is provided in a housing that houses at least a part of the refrigeration space, and is movable with respect to the housing for entering and exiting the refrigeration space. A swing lever for moving the door from a closed position to an open position, particularly around a horizontal swing axis, having at least one door and a door mounting device provided between the door and the housing Relates to those that have an open device.

  In order to allow entry into and out of the refrigeration space of the refrigeration device closed by the door, doors with various door mounting devices that allow the door to move from the closed position to the open position via the opening device are known. For example, German patent application DE 1401078 discloses a door mounting device for mounting a door via a rocking device. For this reason, two swing levers are provided on the side of the door, and the movement of the swing lever can be swung vertically upward. Although such door mounting devices allow unimpeded access to the refrigerated space of the refrigeration device, the swing device is only limited to the extent that the swing mechanism is constrained, in addition to the increasing disadvantageous static preconditions. I found it not suitable. This is because the door that is swung by the swinging mechanism may react sensitively to the load force caused by the swinging. In particular, these swing mechanisms cannot guarantee the long life required for industrial use of refrigeration equipment.

  For this reason, for example, a door attachment device with another opening device having a swinging device with a vertically extending swinging axis is known (US Pat. No. 4,369,632). Moreover, these door mounting devices can guarantee a long service life unlike door mounting devices having a swinging device. This is because neither the part of the opening device nor the door receives a relatively large load when opening. However, a disadvantage of such a door mounting device is that when opening the door it protrudes from the refrigeration device, thereby limiting the range of motion in the refrigeration device. Accordingly, these door mounting devices cannot guarantee unobstructed access, thereby creating a disadvantage for comfort.

  Therefore, the present invention provides a problem of constructing a refrigeration apparatus having a movable door of the type mentioned above so as to guarantee a long life of the door mounting apparatus and an unobstructed access to the refrigeration space with a simple structure. It was.

  According to the present invention, the door mounting device has a support body that is coupled to the swing lever and particularly follows the swing lever, and the support body moves the door from the closed position to another open position with respect to the open position of the other open device. By supporting at least one part of another opening device of the door mounting device for movement, the given problem is solved.

  If the door mounting device has another opening device that moves the door from the closed position to another opening position with respect to the opening position of the other opening device, it is easy to provide a stable swing device according to the present invention. Will be possible. This is because, according to the user's custom, the uniform use of both the possibility of entering and exiting is carried out on average, so that a rocking device can also be provided without special additional structure means. However, if the door mounting device has a support coupled to the swing lever, and the support supports at least one part of another opening device of the door mounting device, the service life can be particularly increased. The door load caused by the swing can thus be removed to the support, thereby improving the door loadability, particularly the stability of the door mounting device. If the support follows the swing lever, a simple structural state occurs. Thus, unlike the prior art, the present invention not only guarantees a long life of the refrigeration apparatus, but also ensures entry and exit of the refrigeration apparatus without any obstacles.

  If the support is provided against the door so that the door mounting device has a support and the support removes force to the swing lever through the support when the door moves around the swing axis, And / or from other opening devices, the forces caused by the rocking can be reduced. Deformation forces caused by rocking can thus be easily removed, thereby relaxing the structural prerequisites for doors and other opening devices. Therefore, a door having a glass surface or a glass door can be provided so as to be able to swing with respect to the prior art, which is particularly advantageous for ease of operation. This is because articles in the refrigerated space can be looked into before the door is opened. Furthermore, the support can increase the safety of the door mounting device by mitigating the risk of destruction of the door or the door mounting device. Therefore, it is possible to improve the force reduction from the swinging door by providing a support for the door so that the support forms a force coupling device in addition to another opening device when the door swings. it can. The support is preferably used for at least partial support of the swinging door. Of course, the swing lever need not always be considered a straight lever. The lever can take the same shape as the support, which can form a variety of transitions.

  If the support has a support frame, it can not only provide a loadable structure for other opening mechanisms, but can also be used as a loadable support. Furthermore, the frame can alleviate, for example, the swinging door load on all sides, which allows a relatively high safety against doors with glass surfaces or glass doors in particular. If the swing lever and the door form a common member, a simple structural state occurs.

  If the support has a horizontal guide part of the sliding guide device, a simple structural state is produced for the sliding guide device. This is because the support can be used structurally for other opening devices configured as sliding guide devices.

  If the other opening device is configured as a rocking device including a rocking bearing attached to the support, and the rocking bearing has a rocking axis that is inclined with respect to the rocking axis and extends in particular at a right angle, An inexpensive suspension device for the door can be provided regardless of the structure.

  In order to prevent uncontrollable swinging of the swinging door, a support provided on the side of the door facing the refrigeration space can limit the swinging range of the door. Thereby, the safety of the door mounting device can be easily improved. This is because when the door is swung, it is limited by the stopper and rests on the support, so that an undesired swinging motion can no longer take place during the swinging of the door.

  In order to increase the torsional strength of the housing with respect to the swing load, it is possible to provide a strut for coupling a force between the housing rear wall protruding from the housing lid and the housing lid.

  When the housing having the supporting skeleton has at least a part of a circulating air circuit for applying a temperature to the refrigeration space between the skeleton supporting body and the lateral coupling piece, the size of the refrigeration apparatus is advantageously reduced. Can do. This is because the guiding device to be provided for the circulating air can be accommodated between the refrigerated space and the outside of the housing, or the housing can be used to form this device. An advantageous viewing condition is provided if the circulating air circuit has an outlet for allowing cooling air to act on the side of the door facing the refrigerated space, at least in the region of the housing opening adjacent to the door. This is because condensed water at the door is easily avoided.

  Depending on the force load to be removed, the oscillating device has two oscillating levers which are spaced apart from each other and extend in particular parallel, and these oscillating levers engage the support frame together, And is attached to the lid of the housing. Further, the refrigerant circulation means of the refrigerant circuit of the refrigeration apparatus is provided in the middle range of both swing levers, so that the structural dimension of the refrigeration apparatus can be reduced.

  In the figure, the subject of the invention is illustrated by way of example.

  The perspective view of 1st Example of a refrigerator is shown.   FIG. 2 shows a side view of the refrigeration apparatus according to FIG. 1.   FIG. 2 shows a front view of the refrigeration apparatus according to FIG. 1 with the door opening door piece open.   Fig. 2 shows an enlarged partial view of the door mounting device of the refrigeration apparatus according to Fig. 1.   FIG. 5 shows a front view of the door mounting device according to FIG. 4.   Sectional drawing of the refrigeration apparatus by the VI-VI line of FIG. 3 is shown.   Another embodiment of the refrigeration apparatus is shown in partial side view.   The partial side view of 3rd Example of a refrigerator is shown.   The partial side view of 4th Example of the refrigeration apparatus which has an open | release apparatus different from another Example is shown.   Sectional drawing by the XX line of FIG. 9 is shown.   The partial side view of 5th Example of the refrigeration apparatus with a support body apparatus different from another Example is shown.   The partial front view of FIG. 11 is shown.   The partial side view of 6th Example of the refrigeration apparatus with a support body apparatus different from another Example is shown.   FIG. 14 is a partial front view of FIG. 13.

  The refrigeration apparatus illustrated in FIG. 1 has a refrigeration space 1 for storing articles to be refrigerated (not shown). The refrigerated space 1 is partially surrounded by the housing 2. The housing opening 3 of the housing 2 is provided with a door 4 having two opening door pieces 5 and 6, and the door 4 is coupled to the housing 2 via a door mounting device 7. The door mounting device 7 enables the movement of the door and can thus reach the article in the refrigerated space 1. The movement of the door is made possible by the opening device 8. The opening device 8 enables the movement of the door 4 around the horizontal swing axis 9 from the closed position 10 to the open position 11, both positions 10 and 11 being known from FIG. An open position 11 indicated by a chain line in FIG. 2 indicates one end position, and the other end position, that is, a swing open position can be imagined, but is not shown for the sake of clarity. This open position 11 is characterized in that the door 4 does not enter the exercise space of the user in front of the refrigeration apparatus. That is, the door 4 is substantially above the housing lid 12 of the housing 2. Since the door 4 has a transparent area 13 and thus partially transmits light, the articles stored in the refrigerated space 1 can be seen from the outside. Furthermore, the door 4 can be configured to be largely or completely transparent or light transmissive. A disadvantage of taking out a cold article is that it may be necessary to open the refrigeration device relatively large by swinging the door 4 so that the article can be removed from the refrigerated space 1. Now, in order to be able to take out improved according to the position of the article in the refrigerated space 1, according to the present invention, the door mounting device 17 is a support 15 following the swing lever 14 of the opening device 8. And the support 15 moves the door 4 from the closed position 10 to a different open position 18 with respect to the open position 11 of the swing device 8. Supports the opening device. Therefore, the ease of operation of the refrigeration apparatus is increased. This is because the swinging device 17 enables the movement of the door 4 or allows the opening door pieces 5 and 6 to swing about a substantially vertical swing axis 19.

  4 and 5, the door mounting device 7 is shown in detail. The swinging device 8 is followed by a support 15 to be welded, and the support 15 is followed by a swinging device 17. The opening device 8 is formed by a rocking bearing 20 and a rocking lever 14, and the rocking lever 14 can rock around a horizontal rocking axis 9 of the rocking bearing 20. The support 15 protrudes from the swing lever 14 at a right angle, and a support means 21 that facilitates swing motion, such as a tension-compression spring, can be applied to the support 15. A rocking device 17 is attached to the support 15, and a portion 16 of the rocking device 17 includes a support 15 and projects from the support 15, thereby a pin 19 ′ that forms a vertically extending rocking axis 19. It can fit into another part 19 'of the swinging device 17, which is another part of the door 14 (not shown). The support 15 is surrounded by an insulator (not shown) in the range of the housing opening 3, thereby reducing the heat conduction of the support 15.

  As can be seen from FIG. 5, the support 15 constitutes a support frame 15 ′ that extends parallel to the side edge of the door 4. In order to reduce the load on the door and other opening devices, when the door 4 moves around the swing axis 9, the support frame 15 ′ of the support 15 is swung at least partially in support of the door 4. A support 15 is provided for the door 4 to serve as a support 22 for the purpose. This can be seen especially from FIG. The support frame 15 ′ provided behind the door 4 is swung together with the door 4, and the support 22 can reduce the load on the door at least on the edge side. This load reduction on the edge side can be performed on the upper side of the door and / or on the lower side of the door. It is also conceivable to reduce the load on the side of the door, for example when the door is bent. Thus, the support 15 allows good force removal to the swing lever 14, thereby providing a stable and secure door mounting device 7. It is also conceivable that the swing lever 14 is advantageously formed with a common member with the support 15 and that the support 15 and the swing lever 14 are composed of one piece.

  As can be seen from FIGS. 2 and 3 in particular, if the support body 15 provided on the door side facing the refrigeration space 1 limits the swing range of the door 4 by the support 22, the reliability of the operation of the refrigeration apparatus is particularly improved. Can be improved. A support 22 is provided on the support frame 15 ′ with respect to the door so that the door 4 or the opening door pieces 5 and 6 do not move excessively vertically or swing when the door 4 swings. . Although it is conceivable that an additional means is provided between the support 15 and the door 4 to form the support 22, the support 15 is still useful for the support 22. This is because the door 4 removes the load in addition to another opening device at the support 15 when the door 4 swings.

  Between the housing rear wall 23 protruding from the housing lid 12 and the housing lid 12, a support column 24 for coupling force is provided.

  The oscillating device 7 further has two oscillating levers 14 extending in parallel with a distance from each other, and a refrigerant circulation means 25 of the cooling device is provided in an intermediate range between these oscillating levers. This may be, for example, a compressor, so that this compressor may not be provided at the bottom of the refrigeration device, which allows a low charging edge of the refrigeration device. Further, a swing lever 14 extending in a different manner is also conceivable.

  A housing 2 with a supporting skeleton defines a circulating air circuit 26 that acts on the refrigerated space, at least in part, between the skeleton supporting body 2 'and the transverse coupling piece 2 ", as can be seen from FIG. In order to reduce the formation of condensed water, the circulating air circuit 26 faces the refrigeration space in the area of the housing opening 3 adjacent to the door 6. An outlet 27 having a nozzle 28 that applies cooling air to the side of the door to be circulated is provided, and an outlet is provided in the housing lid 12 to perform forced circulation of the cooling air, and a blower 30 provided in the housing bottom 29 is provided with an inlet 31. Then, at least air from the outlet 27 enters the circulating air circuit 26. Further, the housing rear wall 32 has a refrigerant circuit evaporator 33 for cooling the cooling air introduced into the circulating air circuit 26. It is accommodated. Further in the housing rear wall 32, a nozzle 28 is provided by the lateral coupling piece 2 ", thereby directing cooling air to the article (not shown) that is stored on the shelf 34. Furthermore, the refrigeration apparatus has a handle 35 for operating the opening door pieces 5 and 6. A heat insulator 36 is advantageously provided on the outside of the housing.

  FIG. 7 shows another embodiment of the opening device 8 '. Unlike the opening device 8 shown in FIG. 4, this opening device 8 ′ has a double-arm rocking lever 14 ′ that is attached to a lateral support 24 ′ via a rocking bearing 20 ′. Via the lever extension 14 ″ of the swing lever 14 ′, a support means 21 ′, for example a tension-compression spring, acts to facilitate the swinging movement of the door 4. The support means 21 ′ is movable in the housing 2. A support frame 15 ′ provided behind the door 4 is swung together with the door 4, and the load on the door can be reduced by the support 22. A particularly good force relief on the ′, especially by the lateral struts 24 ′ engaging the substantially outer end of the housing lid 12 and the protruding housing rear wall 23, improving the rigidity in the refrigeration device lid area 12. be able to.

  FIG. 8 shows another embodiment of the opening device 8 '. Compared with the embodiment according to FIG. 2, this opening device 8 'has a double arm swing lever 14' as in FIG. In contrast to the tension-compression spring shown in FIG. 2, this embodiment contributes to facilitating the swinging of the door 7 by means of a tension bar 38 which is guided via turning rollers 37 and tensioned by tension means 39. It has supporting means 21 '. As the tension means, for example, a tension weight, an electric motor or a tension-compression spring can be used.

  Still other opening devices can be configured as the sliding guide device 40, according to FIGS. 9 and 10, as another embodiment. The support 15 preferably has a horizontal guide device 41 of the sliding guide device 40, which reduces the construction costs. Since both opening doors 5 and 6 run side by side on the rollers 42 in the guide device 41, the opening and closing doors 5 and 6 can move into and out of the refrigerated space 1. 9 and 10 show partial views. However, it is clear that the same guiding device need not necessarily be provided at the lower end of the door. As can be seen from FIG. 5, the support 15 also constitutes a support 22 on the upper side surface of the door 4 or the opening door pieces 5 and 6 in addition to the guide device 41. Further, the support 15 similarly has a support frame 15 ', and the door pieces 5 and 6 can enter into these support frames 15', respectively. However, this is not only advantageous for thermal insulation, but the support frame 15 'also serves as a support 22 here. This is because when the door is swung, the side surface of the door 4 or the side surface of the open door 5 adjacent thereto can be placed there.

  Another embodiment is shown in FIGS. 11 and 12, where another opening device is configured as a rocking device 17 '. Unlike the oscillating device 17 of FIG. 4, the oscillating lever 14 is coupled to the support 43 via an oscillating device 17 '. Therefore, the swing lever 14 has a portion 16 'of the swing device 17' of the door mounting device 7 for moving the door 4, and the portion 16 'protrudes from the support 43, thereby forming a swing axis 19 extending vertically. The pin 19 'that engages can fit into other parts of the rocking device 17'. The support 43 is attached to the door 4 via a plurality of coupling means 44, whereby the deformation force caused by swinging can be easily removed from the door 4, which is the case in a door with a glass surface or a glass door. Particularly advantageous. The support 43 is provided between the swing lever 14 and the door 4 and can be used for supporting the swinged door. The support body 43 is provided with respect to the door 4 so that the support body 43 is movable in the direction of the swing lever 14 when the door 4 moves around the swing axis 9. It serves as a support 22 for supporting the swinging door. However, in this case, the support 22 is provided between the support 43 and the swing lever 14 and is not provided between the support 15 and the door 4 as shown in FIG. FIG. 11 shows a considerable distance between the support 43 and the swing lever 14, the width of which is determined by the possibility of movement of the support 43 in the direction of the swing lever 14. For example, it is conceivable to reach the support 22 by overcoming this distance by an allowable deformation force.

  Another embodiment is shown in FIGS. 11 and 12, the support 43 'is a part of the door 4, and supports the support 43' glass surface 13 and a part of the swinging device 17 '. Again, when the support 43 'moves toward the swing lever 14 when the door 4 swings, the swing lever 14 serves as a support 22 for the support 43'. The support body 43 ′ is configured such that the door 4 can be rocked without being disturbed by the rocking lever 14.

  Furthermore, it is generally conceivable to insert means that contributes to the formation of the support between the support and the swing lever or door before the door swings or instead of the door movement.
