Description

GERMAN

To buy frozen items are self-sellers became known, in which the goods shafts housed in an ice compartment and from several sides are surrounded with ice. The goods shafts of this type, which are designed without shaft bottoms Self-sellers stand; one over the discharge openings the cooling housing from the ejection device separating partition. Occupational Self-Seller the discharge openings are closed by sliders. After inserting coins, they are moved by a push member so far that the goods pass through the ejection openings falls into goods removal.

The cooling effect of such self-sellers is low because the cold only indirectly affects the Shaft walls separated from the ice mass pieces of goods is delivered. By not being hermetic closable discharge openings also penetrates warm air into the goods chutes, so that the cooled The temperature prevailing in the self-seller's room is adversely affected.

There are also known self-sellers with several product shafts, in which the product shafts are arranged in a common cooling container, the walls of which are connected to a cooling unit Evaporator plates are formed. With such a common * arrangement of several goods chutes within a common cooling container is the degree of cooling of the individual goods chutes depends on their position in relation to the evaporator plates. It is also with such a self-seller not possible to sell unrefrigerated items from one of the product chutes.

The invention avoids the stated disadvantages. She suggests that each one be frozen for sale Goods chute as a self-contained, all-round insulated cooling container is formed, the bottom plate and side walls connected to the cooling unit, per se known evaporator plates exist. This inventive training of a self-seller it is possible to evenly cool the goods shafts and also subsequently a goods shaft that is used for Issue of cooled items of goods is designed, against such for the issue of uncooled items of goods exchange or vice versa.

According to a further embodiment of the invention, the evaporator plates of the side walls preferably have the cooling container has a shape profiled to the pack of goods. In a further development of the invention the side walls of the goods shafts are provided with openings above the container bottom, pass through the ejection organs when the goods are sold. These openings are after reset the ejection organs in their rest position by iso-

lating means closed again, according to a further embodiment of the invention on the ejection organs are appropriate. This creates a hermetic seal against the outside temperature; Cold losses are largely excluded.

Further features of the invention are the embodiment shown in the drawing and the Refer to the claims.

The embodiment shown in the drawing shows a vertically cut goods shaft 10, which is constructed as a rectangular column and behind the front wall 11 of a self-seller for frozen pieces of goods is arranged. It consists of the side walls 12 and the base plate 13. This represent evaporator plates in the known type, which are attached to one below the goods shafts in a special Part of the self-seller housed cooling unit 14 are connected, which the coolant pushes through the finned tubes 15 of the side and bottom walls. The ones forming the goods shaft Evaporator plates 12, 13 are surrounded by an insulated layer 16 to prevent heat radiation into the To prevent the inside of the shaft. The filling opening of the shaft is closed with an insulated cover 17.

Above the shaft bottom 13, at the level of the lower packages of goods, are in the opposite side walls 12 and the insulation layer 16 recesses 18, 19 are provided, of which the opening 18 serves to exit the lower packs of goods. The opening 19 penetrates the ejector 20, which is in Embodiment is designed in the form of a transport bolt. When pulling out the drawer-like trained slide 21 is through the ejection

organ 20 conveyed the lower package of goods through the output opening 18 to the outside. Through insulating plugs 22, 23, which are expediently attached to the ejection elements 20, 21, become the openings 18, 19 hermetically sealed when the slide 21 is returned to the rest position.

By attaching devices, not shown, on the sides facing the inside of the shaft Evaporator plates, an air gap can be achieved between the goods packs and the shaft walls, by which freezing of the packaged goods is prevented in a known manner.

The cooling shaft can also be pivotably attached in its lower part by suitable means. For easy refilling with goods, this is swiveled out at its upper end in a manner known per se. In addition, additional adjustable sheet metal walls, which are also known per se, can be used in the Inside the goods chutes are attached, so that the sale of smaller items of goods from one Cooling shaft can be done.

The design of the goods shaft according to the invention also makes it possible to use it as a closed unit in machines next to shafts, out of which are uncooled Goods are sold without influencing these goods.
