DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) FIG. 1 is a perspective view of a device 1 for cooling or frosting a container 2 according to an embodiment of the invention. The device 1 is configured as a single glass freezer and supports one container 2 to be chilled or frosted which in this case is a beer glass which is supported in the container receiving portion 3 of the device 1.

(7) FIG. 2a and FIG. 2b are respective views of a device 1 for cooling or frosting a container 2, wherein FIG. 2a is a partial sectional view and FIG. 2b a top view on the central part of the device 1. As can be seen in FIG. 2a the device 1 comprises a container receiving portion 3 in its central part in which a container 2 such as a glass to be chilled can be placed upside down. The container receiving portion 3 is comprised in a base 4 and has two air inlets 5, 5 through which cold air indicated by the arrows is blown with high speed by fans 6, 6 into an annular chamber 7. In order to achieve a swirling air flow in the annular chamber 7, the air is blown into the annular chamber 7 tangentially. By the so-called Coanda effect, air will be directed on the inner surface 8 of the container 2 which has been placed in the container receiving portion 3 in a thin layer. Further, the swirling air moves upwards along the inner surface 8 of the container 2 until it reaches the bottom of the container 2 from where the air is sucked out of the container 2 into a central pipe 9 of an air outlet portion 10 of the container receiving portion 3 which pipe 9 from the container receiving portion 3 extends upwards into the container 2. The swirling air is sucked out of the container into the central pipe 6 by means of an additional support fan which is not shown here. The used air is sucked downwards through the pipe 9 of the air outlet portion 10 which is connected to a cooler block 11 via a cooler block air inlet 12 (see FIG. 3b).

(8) FIG. 3a and FIG. 3b are respective sectional views of a device 1 for cooling or frosting a container (not shown here) according to still a further embodiment. The device 1 is basically configured as the device 1 already described above in connection with FIG. 2a and FIG. 2b. However, as can be seen here in FIG. 3b, the base 4 with the container receiving portion 3 is connected to a cooler block 11 in which the air used to chill the container 2 (see FIG. 2a) which is still cool but slightly warmed up compared to the air introduced into the annular chamber 7 at the two air inlets 5, 5 is cooled down to an appropriate temperature again. As described above, the used air is sucked out of the container 2 through the central pipe 9 and is introduced into the cooler block 11 at its cooler block air inlet 12. From there, the air is circulated through the cooler block 11 several times by passing through several sections (only indicated here schematically by several arrows) into which the cooler block 11 is divided to achieve an efficient cooling of the air which after having passed through the entire cooler block 11 reaches a predetermined temperature at which it is reintroduced into the base 4 and the container receiving portion 3 through two cooler block air outlets 13, 13.

(9) FIG. 4a and FIG. 4b are respective views of a cooler block 11 of the device 1 for cooling or frosting a container shown in FIG. 3a and FIG. 3b. As can be seen, the cooler block 11 is formed as an evaporator with a piping 14 which is arranged such that it meanders back and forth between the short sides 15, 15 of the cooler block 11 and through which a cooling liquid is circulated. A plurality of cooling ribs 16 is arranged between the piping 14 so as to make the heat transfer between the piping 14 and the air passing through the cooler block 11 more efficient. Thus, a temperature difference of at least 30 C. of the air circulated in the cooler block 11 from the cooler block air inlet 12 to the cooler block air outlets 13, 13 (see FIG. 3b) can be achieved.

(10) FIGS. 5a to 5d are respective perspective views of the device 1 for cooling or frosting a container 2, as shown in FIG. 3a and FIG. 3b. As can be seen in the figures, the fans 6, 6 for blowing air with high speed into the annular chamber 7 are equipped with external engines 17, 17 to keep any heat generated by the latter during operation out of the air flow path.
