Description

The The invention relates to a cooling device with Foldable goods edition according to the characteristics of the preamble of the main claim.

such coolers be used for cooling of perishable foods, such as Snacks, bakery and Pastry, meat and dairy products, etc. used. The coolers are included in sales counters and self-service counters.

A such cooler consists of an insulated tub, on the at least one Warenauflagefläche for Recording the goods to be cooled is arranged. In the tub is a cooling arrangement, consisting of at least one evaporator, which with a refrigeration unit, the outside the goods space is arranged, is connected and one or more Fans for air circulation.

Around the goods opposite protect the surrounding area, is the goods support surface usually covered with a counter glazing towards the top.

The air duct takes place at refrigerated counters usually so that the air cooled by the evaporator from the open operating side over the goods support surface for closed customer side is blown and there again from the fan is sucked in.

Since condensation forms in the tubs and accumulates impurities, the tubs and the interior must be cleaned regularly. In circulating air cooling, the goods support can be folded up together with the evaporator and, in the upper position, self-retaining by means of a gas pressure spring, so that the tank bottom is accessible for cleaning. This is for example in the DE 201 00 881 U1 and the DE 197 10 336 C2 shown. Another way to clean the counter interior is eg in the DE 32 01 819 A1 dargesellt. Here, the goods support and evaporator package can be set up one after the other, so that both the complete floor area and the evaporator are easily accessible for cleaning.

In order to additionally clean the circulating air flow of dust, viruses and bacteria, circulating air cooling systems are increasingly being equipped with a filter and / or disinfection unit. This is for example in the DE 200 11 051 U1 , in the DE 201 01 627 U1 and the DE 101 34 545 A1 shown.

newer forced air cooling for baked goods, snacks and the like are usually easy in the horizontal or slightly inclined to the customer work surfaces. To the customer side towards a glass structure is built. This glass construction often only has has a height by Max. 350-400 mm. In many cases is within the glass structure still an intermediate floor for uncooled food present, allowing a convection cooling For cleaning often only about 250 mm can be swung.

There the customer-side windshields usually not like the known butchers are hochschwenkbar, these Umluftkühlungen in most cases built to be cleaned from the operator side can.

It is not possible for the goods display a large opening angle, as in the DE 32 01 819 A1 presented to provide.

To be able to clean the evaporator anyway, as in the DE 297 11 452 U1 shown, the fan arranged on the side of the hinge of the goods support and the evaporator is attached to the movable goods support movable. Thus, after folding up the goods support with evaporator, the evaporator can be folded down again so that it can be cleaned with a water shower or similar. is easily accessible.

In Modern counter shapes often make the convection cooling tray easy to the customer installed inclined. This also has the flow in the area of the swivel joint to be ordered.

When using filter units, such as in the DE 101 34 545 A1 shown, these are also installed on the hinge side.

Around for maintenance to the fans or to the degermination device to go to check the filters and to change or to clean only the drain, the Goods display around a big one Angle can be swung up. However, this is in the beginning mentioned establish not possible in practice due to the glass structure.

In order to are fans, condensate drain, filters and sterilizers for maintenance and inspection only after disassembly of the upper goods display or the disassembly of the upper glass top and after swinging the upper goods delivery by a large rotation angle possible.

The invention has for its object to design a device for cooling food, which the disadvantages mentioned above avoids, which allows easy cleaning of the entire tank bottom and the evaporator and which at the same time allows easy accessibility to the arranged in the hinge, fans, filters, sterilization facilities, etc. for maintenance, inspection and cleaning and the total cost is to produce.

According to the invention, evaporators ( 7 ) and Warenauflage ( 3 ) via a respective rotary joint ( 23 + 15 . 22 + 15 ) with the tub ( 5 ), wherein the axes of rotation of the two rotary joints ( 23 + 15 . 22 + 15 ) have the same direction, the two axes of rotation are arranged on the same side of the tub and wherein the rotary joint ( 22 . 15 ) between tub ( 5 ) and Warenauflage ( 3 ) is formed by a detachable connection.

This allows the goods circulation ( 3 ) independent of the evaporator ( 7 ) are raised. Both sides of the evaporator ( 7 ) are accessible for cleaning. Because the swivel ( 22 . 15 ) is formed by a detachable connection, the Warenauflage ( 3 ), so that the rear evaporator area with fans ( 20 ), Filtering ( 12 ), Outflow ( 14 ) etc. is easily accessible.

The swivel joint with the detachable connection ( 22 . 15 ) becomes advantageous according to claim 2, ie by a bolt ( 15 ) and a counterpart having a groove-like opening ( 22 ) in which the bolt ( 15 ) is guided during the rotational movement.

Several major improvements can be made by combining the goods ( 3 ) with the tub ( 5 ) via lifting means ( 9 ) according to claim 3. On the one hand, even heavy goods orders ( 3 ) for cleaning the bottom of the tub. Furthermore, the goods order ( 3 ) are made self-holding in the upper position. In the lower position and during pivoting, the lifting means ( 9 ) the goods edition ( 3 ) with the groove-like openings ( 22 ) against the with the tub ( 5 ) connected bolts ( 15 ). The goods edition ( 3 ) can not inadvertently from the hinge ( 22 . 15 ) jump. Are used as lifting means gas springs ( 9 ) used according to claim 4, the folding up of heavy goods ( 3 ) simplified. At the same time, the goods order ( 3 ) then self-holding in the upper position.

The gas pressure springs ( 9 ) have yet another advantage: when in the open state at the merchandise display ( 3 ) pulled at this by the operator, the bolt slips ( 15 ) from the groove-like opening ( 22 ). The goods delivery ( 3 ) is now only via the gas springs ( 9 ) with the tub ( 5 ) connected. The gas pressure springs ( 9 ) are treated in this situation like fixed-length levers. Will continue at the goods support surface ( 3 ), this is about the lifting means ( 9 ) guided on a circular path to the operator. The goods edition ( 3 ) can thus by about 1.5 to 2 times the opening stroke of the gas spring ( 9 ) are pulled forward. The rear evaporator section is now freely accessible, the goods support ( 3 ) has a fixed position and does not need to be set aside.

Will the swivel joints ( 22 + 15 . 23 + 15 ) of goods support surface ( 3 ) and evaporators ( 7 ) designed so that they form a common axis of rotation is on the tub ( 5 ) only one bolt ( 15 ) necessary for both hinges. This simplifies the assembly (claim 5).

If the evaporator ( 7 ) according to claim 6 via a detachable connection ( 17 + 18 ) with the goods support surface ( 3 ), then when opening the goods support surface ( 3 ) the evaporator ( 7 ) with raised so that the bottom of the tub is immediately accessible for cleaning. After releasing the connection ( 17 + 18 ), the evaporator ( 7 ) can be folded down again and if necessary, the Warenauflage ( 3 ) are pulled forward.

It simplifies the production of circulating air cooling, if according to claim 7, the fans necessary for air circulation ( 20 ) with the evaporator ( 7 ) get connected. Also remain after the folding of the evaporator ( 7 ) no baffles or similar more at the bottom of the tub.

When using recirculating air filters ( 12 ) and degermination devices ( 11 ), it is also appropriate, this according to claim 8 with the evaporator ( 7 ). The evaporator unit with fans ( 7 ), Filters ( 12 ) and sterilization device ( 11 ) can then just outside the tub ( 5 ) and only needs in the tub in the final assembly ( 5 ) to be used.

The Drawings illustrate two particularly suitable for installation in counters Embodiments.
