| 摘要 | A vaporizer-humidifier having a small insulated vaporization chamber within a larger storage chamber, heating means within the vaporization chamber and a fan above the chamber for drawing air through and vapor from the vaporization chamber and dispelling it. The vaporization chamber has an open lower end communicating with a sediment collecting reservoir, which reservoir is connected by a one-way valve with the large storage chamber to permit liquid therein to flow into the sediment collecting reservoir and then up into the vaporization chamber as the liquid therein is vaporized. Sediment purged from the liquid settles in the removable sediment collecting reservoir. | ||||||
| 权利要求 | 1. A vaporizer-humidifier comprising means defining a supply reservoir, chamber means defining an insulated vaporization chamber within said supply reservoir, said chamber means comprising a tubular member having opposite open ends disposed in vertically spaced relationship, the lower open end being a reduced opening, container means disposed beneath the lower open end of said tubular member, said container means being secured in fluidtight condition with said tubular member and in communication with said chamber means through said lower open end for receiving minerals purged from a liquid therein, passage means affording the flow of liquid from said supply reservoir to said vaporization chamber, immersion heating means disposed in said vaporization chamber for heating liquid therein, and blower means positioned with an inlet above said open upper end of said vaporization chamber and an outlet for removing vapor and ambient air therein from said vaporizer-humdifier. 2. A vaporizer-humidifier as described in claim 1 wherein said passage means define a passage and a one-way valve means therefore between the container means and the supply reservoir to permit liquid to flow therethrough into the vaporization chamber and to prevent any warm liquid from moving from the vaporization chamber to the supply reservoir. 3. A vaporizer-humidifier according to claim 1 wherein said heating means comprises a resistive immersion heater which has helical coils disposed in said tubular member. 4. A vaporizer-humidifier according to claim 1 wherein said heating means comprises a protective outer sheath and an electrical resistor positioned within and insulated relative to said sheath, and a thermostatic control adjacent said heating means to prevent heating thereof significantly above the boiling temperature of water. 5. A vaporizer-humidifier according to claim 1 wherein said tubular member comprises a hollow cylindrical member positioned vertically within said supply reservoir and having a funnel-shaped lower end terminating in said reduced opening, said container means comprises a receptacle removably supported beneath said tubular member and a portion of said supply reservoir, said passage means comprises an opening into said receptacle from said supply reservoir, and a one-way valve is positioned in said passage means to allow the flow of liquid only from said supply reservoir to said vaporization chamber. 6. A vaporizer-humidifier according to claim 1 wherein said tubular member has a scale resistant coating on the interior surface thereof. |
