DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a bottle cooler wherein bottles, cans and similar containers, preferably containing beverages, are offered for sale in cooled condition.
Prior art includes cabinet-shaped refrigerating counters wherein the bottles, of which the liquid content is to be cooled, are placed on shelves. In such a refrigerator, it is not easy to get oneself a view of what kind of drinks are contained in the cabinet on the various shelves. Cabinet-shaped refrigerating counters have a swingable door at one of the four sides. Thus, such a refrigerating counter is poorly suited to be placed in the middle of the business premises in order to attract maximum attention for sale-promoting purposes. A negative feature in this respect is that the bottles in fact are kept concealed within the cabinet and can only be seen when they are located close to the glass door, preferably when the latter is swung open.
SUMMARY OF THE INVENTION
In accordance with the present invention, one has aimed at eliminating deficiencies, disadvantages and limitations of use relating to prior art technique and, thus, providing a refrigerating counter of the kind defined introductorily, exhibiting a sale-promoting construction wherein bottles and/or similar containers for beverages become easily visible, and including a suitable storage which may be filled with bottles which, thereafter, as bottles are removed from the display shelf of the bottle cooler, automatically refills said display shelf, and wherein provision has been made for an adequate cooling system comprising recovery of cooled air, possibility of evaporating formed condensate, etc.
According to the invention, said objects are realized through designing a bottle cooler of the kind concerned, in accordance with the features appearing from the following claims.
A bottle cooler according to the invention comprises an in per se known cooling machine which is positioned in the lower portion of the bottle cooler.
Above the cooling machine, the bottle cooler has been built up on a standing pipe having at least one through-going opening at the upper portion thereof: which is surrounded by a downwardly open hood. A distance beneath the lower edge of the hood, a support shelf for bottles, cans and/or other containers for beverages is disposed. In the area of this shelf, in the adjacent wall surrounding the standing pipe, perforations are formed.
When the cooling machine produces cooled air, this air will be brought to flow upwardly (against its natural flow direction) by means of a fan, from the lower end of the standing pipe to the upper portion of the standing pipe and out through said opening(s) and into the room surrounded by the hood. Here, the larger weight of the cooled air can be utilized to let it "fall" down onto the bottles which are stacked upon the support shelf which, in the circumferential direction, may extend wholly or in part around the standing pipe. During the air's downward flowing, the cooled air cools the bottles and, thus, the content thereof, such that condensate is formed. This condensate becomes drained off as it is formed through the perforations in said wall portion surrounding the standing pipe.
Thus, said condensate is drained off together with cooling air which has accommodated some heat from the bottles, through said perforations, and lands ultimately on a heating plate adapted to evaporate the condensate and which may be based on the use of heat gas pipes.
The evaporator of the cooling machine will be placed within a widened lower portion of the standing pipe, beneath the fan for the cold air's transport upwardly within the standing pipe. Below a horizontal wall having a vertical, central pipe for conveying condensate to said heating plate, a compressor and an air-cooled condenser have been disposed, opposite said heating plate.
The necessary amount of air for the condenser is taken in through the perforations in the bottom portion of the bottle cooler's double-walled casing. This air is then about 10.degree. C. higher
