DUST COLLECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/058141
Kind Code:
A1
Abstract:
The present invention provides a dust collecting device in which the area of a dust passage is widened to prevent the dust passage from being clogged by the dust separated by centrifugal force from outdoor air and flowing downwardly. To this end, the present invention comprises: a dust collection tank, to one side of which a first air supply pipe for supplying outdoor air is connected and which has an open lower end; a first air discharge pipe arranged in the inner top of the dust collection tank so as to discharge the outdoor air which is supplied to the dust collection tank and from which dust is removed by centrifugal force; a conical induction block which is arranged in the open lower end of the dust collection tank, and which is formed into a conical shape having a diameter that increases from the top vertex to the lower end thereof so as to induce swirling of the outdoor air; a dust passage formed between the circumference of the lower end of the conical induction block and the inner wall of the lower end of the dust collection tank so as to pass the dust separated from the outdoor air by centrifugal force; and a first dust collector having a dust storage tank, arranged beneath the dust collection tank, for storing the dust that has passed through the dust passage.
