- the nozzle equipment 10 in accordance with the invention may be disposed in different arrangements in connection with tables 11 and in different table applications.
- An elongated slot nozzle preferably extending over the entire length of the bar counter is advantageously used as the nozzle in the nozzle equipment.
- Fig. 2A shows a first advantageous embodiment of the invention, wherein a body 200 of nozzle equipment 10 is disposed in connection with a table 11 in a gap TJ between table-top parts Hat or 11 a 2 or in an elongated groove made in the table.
- the nozzle equipment 10 includes a slot nozzle 12 formed by plate parts 12' attached to a round part 12" which is articulated to turn in a round cradle 12'".
- the nozzle 12 can be turned in a manner known in itself into different control positions in order to direct an air jet in desired directions.
- the nozzle extends over the entire length of the table, such as a bar counter.
- the body of a collecting chamber 30 of an openable space 120 for collecting impurities is designated by reference numeral 300.
- the nozzle 12 is disposed with its turning bearings in a nozzle body 120 and the entire structure is detachably attached as one entity to the chamber 13 collecting impurities, such as liquid, by means of a quick-release fastening means 100.
- the impurities collecting chamber 13 includes an air supply chamber 14 as the supply duct.
- the nozzle equipment 10 can be opened at its body 200 over the entire length of the collecting space 130 and the collecting chamber 13 so that the chamber 13 collecting impurities, such as liquids, in its impurities collecting space 130 may be cleaned.
- the collecting chamber 130 can be opened over the entire length thereof from the side of the elongated equipment 10 for the purpose of cleaning.
