Abstract

FIELD: dust removal equipment. SUBSTANCE: dust suction apparatus (vacuum cleaner) has suction nozzle and dust accumulating bag 12 connected with nozzle through, for example, tubular device, turbofan unit 27 driven by electric engine and positioned behind dust accumulating bag in the course of flow. Impeller 29 of turbofan unit 27 is driven at frequency above 50.000 rev/min. Apparatus is constructed such that main air flow created by turbofan unit 27 exits directly or indirectly from unit 27 into atmosphere through outlet channel 30. Device 45 facilitates creation of auxiliary air flow, which at least partially cools electric engine 32 and is delivered into electric engine through cooling air inlet channel 44, which is separated from main air flow. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation.

Claims (1)

Изобретение относится к устройству для всасывания пыли (пылесосу), имеющему всасывающее сопло и пылевой мешок 12, который соединяется с соплом, например, с помощью трубчатого ствола, узел 27 турбовентилятора, приводимый во вращение электродвигателем и расположенный за пылевым мешком по направлению потока. Крыльчатка 29 узла турбовентилятора приводится во вращение с частотой, которая составляет свыше 50000 об/мин, причем конструкция выполнена так, что основной поток воздуха, создаваемый узлом 27 турбовентилятора, выходит из узла в атмосферу через выходной канал 30 прямо или косвенно. Пылесос оснащен средством 45, с помощью которого создается вспомогательный воздушный поток, который частично охлаждает электродвигатель 32 и который поступает в электродвигатель через один или несколько входных каналов 44 для охлаждающего воздуха, отделенных от основного воздушного потока.The invention relates to a dust suction device (vacuum cleaner) having a suction nozzle and a dust bag 12, which is connected to the nozzle, for example, by a tubular barrel, a turbofan assembly 27 driven by an electric motor and located behind the dust bag in the flow direction. The impeller 29 of the turbofan assembly is rotated at a frequency of more than 50,000 rpm, the structure being such that the main air flow generated by the turbofan assembly 27 exits the assembly into the atmosphere through the outlet channel 30 directly or indirectly. The vacuum cleaner is equipped with means 45, by means of which an auxiliary air stream is created, which partially cools the electric motor 32 and which enters the electric motor through one or more inlet channels 44 for cooling air, separated from the main air stream.
