Definitions

  • the invention relates to a display case for fruit and vegetables with a receptacle inclined forward on a support frame for the use of fruit or vegetable boxes.
  • fruit and vegetables are offered for self-service in their own display cases, in which the open fruit and vegetable crates are lined up in receptacles and arranged here in two or three rows one behind the other.
  • the sales showcases are usually equipped with mirror walls behind the receptacle for better clarity, but fruit and vegetables are freely offered for free removal and there is no possibility of quality-assuring storage, so that the goods are sold as perfect fresh goods for only a few hours, at most one day can.
  • Experiments with cooling devices for the receptacles with forced air cooling u. The like. brought no noticeable benefit, which combines the sale of fresh goods, in particular the sale of fresh vegetables, with a high reject percentage of the quickly aging and spoiling goods.
  • the invention is therefore based on the object to remedy these shortcomings and to create a display case of the type described, which offers the best storage conditions for fruit and vegetables with comparatively little additional effort and helps to significantly extend the keeping time of the goods.
  • the invention solves this problem in that the receptacle as a freezer with a trough-shaped chest body and a transparent lid and along of the chest body wall, which is connected to a cooling unit, is formed with cooling coils, the cooling coils running essentially in the wall parts of the rear area of the chest body.
  • the invention is based on the knowledge that the freshness of fruits and vegetables depends to a large extent on the moisture content of the ambient air and on a uniform cooling temperature level in the storage area, thereby preventing the goods from drying out as much as possible.
  • the freezer which is dimensioned as a receptacle, now offers enough space, like a conventional receptacle, for inserting the standardized fruit and vegetable crates, so that the goods can be offered in a conventional manner and only a transparent lid only allows access after opening.
  • a desired fresh-keeping climate with static cooling can develop, the lack of air circulation keeping the moisture inside the chest body and preventing the goods from drying out.
  • the unevenly distributed cooling coils cool in the rising, rear chest area, whereby the cooled air slowly descends down the floor into the front chest area and leads to a barely noticeable, but the uniformity of the temperature, which entails air circulation.
  • the cooling coil-free wall parts in the front chest area prevent the front storage area from overcooling and thus ensure the desired even temperature distribution.
  • the arrangement of the trough-shaped freezer as an inclined receptacle with the cooling specially adapted to this inclined position brings with it a surprising increase in the shelf life of fruit and vegetables, so that the goods as fresh goods are not only perfect for one, but up to 3 and 4 days can be offered and the committee share can be kept very low.
  • the cooling coils can be laid in any arrangement if they bring about the uniform cooling temperature with consideration of the cold flow with an inclined freezer.
  • the cooling coils could be distributed over the floor with a decreasing surface density, but it is expedient if the cooling coils are laid in the rear half of the chest body floor and in the rear wall of the chest body, since this is also the case with conventional cooling coils that are limited to these wall areas desired uniform temperature distribution is achieved.
  • the side walls of the chest body can also remain free of cooling coils, which simplifies installation and, above all, facilitates the side-by-side arrangement of individual sales cabinets to form larger sales units.
  • the freezer can be closed with a lid, the transparent lid allowing a clear view of the chest and therefore only needs to be opened to remove the goods.
  • the cover has sliding parts which are supported on rollers on rails of the chest body, the rollers being adjustable in terms of stroke and can be pressed down from a raised release position into a lowered support position by means of an actuating handle .
  • the sliding parts of the lid can be easily opened and closed despite their considerable dimensions and weights due to the large chest opening due to the roller support, but at the same time the actuating handle limits the mobility to the desired displacement.
  • the actuating handle If the actuating handle is actuated, it only presses the support rollers into their supporting position, in which they can roll on the running rails and allow the sliding parts to be moved easily by means of the actuating handle. If the actuating handle is released, the dead weight of the sliding parts brings the castors back from their supporting position to their free position, in which the sliding parts sit on the running rails without roller support and their mobility is braked so that any unwanted sliding part movement does not occur.
  • a simple operative connection between the actuating handle and the roller adjustment is achieved in that the actuating handle engages on the actuating rails via pivoting levers articulated on the support rails, preferably a pair of oppositely inclined wedge surfaces is assigned to the bearing journals of each roller.
  • the pivoting movement of the driver levers can thus be used for the sliding adjustment of the actuating rails, the pair of wedge surfaces bringing about a corresponding actuation of the roller independently of the pivoting direction of movement.
  • a display case 1 for fruit and vegetables consists of a freezer 3 built on a support frame 2 which is inclined forward, which freezer 3 has a trough-shaped chest body 4 as a receptacle for inserting fruit or vegetable boxes 5, which for example can be placed side by side and one behind the other.
  • the chest body 4 is provided with a transparent cover 6 which, if necessary, is opened by customers for removing the goods.
  • the freezer 3 is equipped with cooling coils 8 connected to a cooling unit 7, only indicated, which run along the foamed wall 9 of the chest body 4, but these cooling coils 8 essentially are only installed in the wall parts of the rear chest body area 10, in the exemplary embodiment shown they are located in the rear half 11 of the tub floor 12 and in the rear wall 13 of the chest body 4.
  • cooling operation taking into account the fact that the cooled air descends along the tub floor 12 from the back to the front, ensures a uniform cooling temperature within the cooling space and prevents overcooling in the front lower chest area .
  • the stationary cooling and the natural, only temperature-dependent air circulation prevent moisture removal from the chest, which creates optimal storage conditions for fruit and vegetables and ensures that the goods are kept fresh for a long time.
  • the chest lid 6 is designed as a sliding lid and comprises two sliding parts 14, wherein for easier actuation each of the sliding parts 14 is supported by rollers 15 on rails 16 of the chest body 4 in the upper edge region of the chest opening, but the rollers 15 are adjustably mounted to avoid undesired sliding movements and can be depressed via an actuating handle 17 from a raised release position into a lowered support position.
  • the rollers 15 on each long side of the sliding parts sit on bearing pins 18 in guide slots 19 of a support rail 20 which are normal to the running rail 16 and can be attached to the bearing pins by means of an actuating rail 21 which is adjustable with the actuating handle 17 and which has wedge surfaces 22, preferably two mutually inclined wedge surfaces 18 attack, adjust the stroke.
  • the actuating handle 17 is pivotally articulated via a driving lever 23 to an abutment 24 of the supporting rails 20, which levers 23 pass through the actuating rails 21 through driving openings 25, so that the pivoting movement of the actuating handle 17 via the driving lever 23 is converted into a sliding movement of the operating rails 21.
  • Due to the interaction of the wedge surfaces 22, bearing pin 18 and guide slots 19, the rollers 15 are pressed down from a raised, non-load-bearing exemption into a supporting position in which they perform their support function and allow the sliding parts to be moved easily.
  • the sliding parts 14 can only be moved smoothly when the operating handle 17 is consciously actuated, when the operating handle 17 is released, however, the support rails 20 rest with the entire sliding part weight on the running rails 16 and block a further sliding part movement, which from the outset can cause injuries due to unskillful handling of the sliding parts helps prevent.
