WIPO Patent Application WO/2021/075178
Kind Code:
A1
Abstract:
This humidifier (70) comprises a second housing (41) that divides an accommodation space (S). The accommodation space (S) accommodates a water storage tank (72). The tank (72) is inserted into and removed from the second housing (41) through an attachment/detachment opening (43K) which is an opening in the second housing (41). A third introduction hole (48) that connects the inside and outside of the second housing (41) is opened in the second housing (41) separately from the attachment/detachment opening (43K). A first tank hole (73) that connects the inside and outside of the tank (72) is opened in the tank (72). Disposed between the second housing (41) and the tank (72) is a first seal member (75) that divides a first downstream-side flow passage, which reaches the inside of the tank (72) via the third introduction hole (48) and the first tank hole (73), and the space outside the second housing (41). The first seal member (75) extends along the inner surface of the second housing (41) when viewed from the insertion/removal direction of the tank (72), and extends so as to entirely surround the periphery of the tank (72).
