WIPO Patent Application WO/2018/212411
Kind Code:
A1
Abstract:
The present invention relates to a vortex spray-type steam head device for a coffee machine, wherein a steam sterilizer, which is used while connected to a steam discharging hole of a coffee machine, sprays steam in a vortex flow. When existing steam sterilizers or the like spray high-temperature steam, the steam is sprayed in a straight line due to steam pressure such that used coffee grounds are discharged from a coffee extraction hole to be cleaned or sterilized in a coffee machine, thus making cleaning or sterilization inconvenient. Furthermore, the problem of noise being generated when the steam is sprayed in a straight line is solved.
