Definitions

  • the invention relates to a refrigeration unit intended in particular for shopfitting, which essentially consists of a cooling table which has a table top on a base for placing the goods to be presented to the customer and which also has a cooling device for at least the perishable goods lying on the table top to be able to keep fresh.
  • Refrigerated furniture for shopfitting is known.
  • the problem with such refrigeration units is that it is difficult or at least cumbersome to clean them and in particular their cooling device after business hours and after the goods to be presented by means of the refrigeration units have been removed from them.
  • Another problem is that the cooling capacity of known refrigeration units is often insufficient because extensive insulation measures have to be taken to enable the cooling air to be cooled without excessive energy losses.
  • the invention has for its object to provide a refrigerator, which is intended in particular for shopfitting, which is easy to clean or easy to clean on the one hand and on the other hand does not require special insulation to achieve the desired cooling performance.
  • the invention makes it possible to clean the surfaces to be cleaned after use of the refrigerator, such as, for example, the top of the table top, but also the guide system for the cooling air, in a simple and uncomplicated manner, because the corresponding surfaces for one convenient cleaning can be made easily accessible if the cooling device and any parts connected to it have been moved from the operating position to a retracted and raised rest position.
  • the cooling device containing an evaporator has a closed channel for the cooling air to be circulated within the refrigerated cabinet, through which the cooling air can inevitably and inevitably flow, insulation of the evaporator against heat radiation to the outside is not necessary, because most of the power of the evaporator becomes through the air flowing through it.
  • At least one shock absorber is installed according to the invention in the movable lever-having adjustment device, which is preferably between one of the levers and the trough-shaped base is articulated and thus adjustable.
  • the articulation point on the one lever can be expediently adjusted or adjusted so that the damping force of the shock absorbers can be optimally used and adapted to the weight of the respective cooling device.
  • the cooling device with the lever linkage and the trough-shaped base is designed as a module-shaped structural unit which can be installed as a whole in a refrigerator and can also be removed again from the refrigerator.
  • the cooling device can therefore continue to be used even after the use of the refrigerated cabinet has ended by installing it in a new refrigerated cabinet such as a new sales counter. This is particularly expedient because the service life of the cooling device is often much longer than the period of use of the refrigerator.
  • a piece of cooling furniture such as a counter can be equipped with additional cooling devices as desired, i.e. Cooling devices can also be retrofitted to those points of a sales counter where cooling was originally not desired or intended.
  • the cooling table (1) intended for shopfitting has a fixed table top (2), from the front end of which a transparent cover plate (3) runs upwards, while on the rear end a worktop (4) is supported by a raised wall (5) is.
  • a cooling device (6) is arranged on the table top (2), which works with circulating and thereby cooled circulating air.
  • the cooling device (6) has a box-shaped housing (7) which, in the operating position, as shown in FIG. 1, covers a trough (8) attached to the table top (2).
  • the box-shaped housing (7) is mounted on the table top (2) and / or the tub (8) by means of angle levers (9) and straight-line levers (10) such that it moves from the operating position shown in FIG. 1 to the position shown in FIG. 2 cleaning position shown can be moved and raised, and vice versa.
  • a channel (11) is arranged within the box-shaped housing (7), which contains an evaporator (12), through which the circulating air to be cooled can flow when the cooling device (6) is in the position shown in FIG. 1 operating position shown.
  • a disk-like axial blower (14) is let into the end wall (13) at the inlet end of the channel (11) on the left in the drawing, said axial fan (14) opening through openings (16 ) Sucks in air from the space between the cover plate (3) and the housing (7) and guides it through the channel (11) and thus the evaporator (12) housed therein.
  • This air is cooled in the evaporator (12), specifically by means of a cooling medium which is passed through a cooling coil (17) and which is led through a pipe (18) serving as an inlet from a coolant source (not shown) and through another, not recognizable in the drawing, Pipe is returned to the coolant source.
  • the air cooled within the channel flows out through an outlet opening (20) located in the corresponding end wall (19).
  • the outlet opening (20) is located under the wedge-shaped front edge (21) of the worktop (4), so that the cooled air leaving the channel (11) is deflected and, so to speak, directed into the space above the cooling device (6) to where the goods to be cooled lie when the cooling table is in operation.
  • a pivotably hinged flap (22) which, in the operating position shown in FIG. 1, is supported on at least one adjusting screw (23) which is screwed into a bushing (24), which is located on an inclined section (25) of the tub (8).
  • the adjusting screw (23) is set so that the trough-shaped flap (22) lies in the operating position with a flange (26) located at the outer or free end of the flap against the underside (27) of the worktop (4), so to speak, sealingly , so that the cooled air flowing out of the channel (11) cannot escape downwards or backwards, but between the worktop (4) or its front edge (21) and the end wall (19) of the housing (7) upwards and thus is deflected and directed backwards in accordance with the inclined position of the end wall (19).
  • the cooling device (6) is supported on two different lever arms, namely at the end facing the cover plate (3) of the cooling table (1) by means of Angle levers (9) and at the opposite end by means of straight levers (10), the latter between their two articulation points (28 and 29) having a greater actual length than the angle levers (9) between their articulation points (30 and 31). Therefore, the rear end of the cooling device (6) is raised more when lifting off the table top (2) than its front end, as shown in FIG. 2.
  • the angle levers (9) lie with their shorter legs (32) on the top (34) of the table top (2) or the bottom of those fastened on the table top Trough (8), so that the cooling device is kept stable in the raised and retracted position, also because the upper articulation point (31) of the angle lever (9) is now on the other side of the lower articulation point (30) as in the operating position (Fig. 1). This results in a so-called dead center lock.
  • Fig. 2 it can be seen that after lifting the cooling device (6) the top (4) of the table top (2) and the interior of the tub (8) are easily accessible for cleaning purposes.
  • the worktop (4) is not in the way when cleaning the table top (2), the tub (8) and the cooling device (6), it is attached to the housing (7) of the cooling device (6) by means of laterally arranged plates (35) and is accordingly lifted off the table top (2) with the cooling device (6) for cleaning purposes, as shown in FIG. 2.
  • the embodiment according to FIGS. 3 and 4 differs from the embodiment according to FIGS. 1 and 2 essentially in that the housing (7) of the cooling device (6) is not only supported on straight levers (10) at the rear end, but also at the front end on straight levers (36), which are however shorter than the levers (10). Also in this embodiment, the dead center locking of the housing (7) described above in connection with the embodiment of FIGS. 1 and 2 is ensured in the retracted and raised position, since the upper articulation point (31) of the shorter straight lever (36) over the lower one Articulation point (30) goes away when the housing (7) of the cooling device (6) is moved from the lowered operating position shown in FIG. 3 to the retracted and raised cleaning position shown in FIG. 4.
  • FIGS. 3 and 4 differs from the embodiment according to FIGS. 1 and 2 also in that at least on one side of the cooling device (6) between the longer straight lever (10) and the upstanding side wall (37) of the tub ( 8) a shock absorber (38) is arranged.
  • this shock absorber (38) is a cylindrical air spring with a cylinder housing (39) and one protruding from the cylinder housing and extendable piston rod (40).
  • the cylinder housing (39) is connected in an articulated manner to the relevant lever (10) with a head piece (41) attached thereto, while a further head piece (42) is articulated on the outer end of the piston rod (40) and is articulated with the relevant side wall (37 ) the tub (8) is connected.
  • a coil spring (43) is freely displaceable, which, when the housing (7) of the cooling device is in the lowered operating position (Fig. 3), from the cylinder housing (39) of the shock absorber (38) against it the piston rod (40) fastened head piece (42) is pressed and thereby set under tension.
  • the longer lever (10) contains a number of holes (44) arranged in series, into which the head piece (41) of the shock absorber (38) in question can be hooked in order to adjust or change the effective lever arm of the shock absorber according to the respective operating conditions can.
  • the shock absorbers (38) serve to facilitate the retraction and lifting of the housing (7) of the cooling device (6) and, on the other hand, to dampen the movement of the cooling device (6) back into the operating position.
  • the coil spring (43) supports this damping effect.
  • shock absorbers (38) are preferably designed as air springs, another type of shock absorber is also conceivable, for example a hydraulic shock absorber.
  • shock absorber (38) it may be sufficient to install a shock absorber (38) only on one side of the cooling device (6). For reasons of symmetry and to counteract tilting of the adjusting mechanism, however, it is advisable to provide shock absorbers (38) on both sides of the cooling device (6).
  • the trough (8) with the cooling device (6) arranged thereon and the adjustment mechanism can be designed as a modular unit be, which can be installed in a refrigerator, such as a sales counter - also retrospectively - and removed from it again, without having to make major changes to the refrigerator itself. Rather, it is sufficient to detachably attach the tub to the table top with the help of screws, not shown, which can be screwed into the table top (2) or inserted through this table top.
