Patent number: 5073967Abstract: A humidifier including a base defining a liquid reservoir; an electrically energized humidification device adapted to induce dispersion of liquid retained by the reservoir; a power supply for supplying electrical current to the humidification device; a control circuit connecting the power supply to the humidification device and including a switch operable in an active state to produce energizing current flow between the power supply and the humidification device and operable in an inactive state to prevent energizing current flow therebetween; and a sensing mechanism operatively coupled to the switch and adapted to sense the liquid level in the reservoir, the sensing mechanism adapted to provide the active state for the switch in response to a minimum liquid level in the reservoir and to provide the inactive state for the switch in response to a liquid level in the less than the minimum liquid level.Type: GrantFiled: July 8, 1991Date of Patent: December 17, 1991Assignee: Duracraft CorporationInventor: Frank Marino

Patent number: 5067169Abstract: A humidifier includes a base defining a boiler cavity, a liquid supply being supported on the base and having a discharge opening communicating with the boiler cavity and adapted to maintain a given level of liquid therein. An evaporation unit is removably mounted on the base and includes an electrically energized heater projecting into the cavity and a magnetically operated switch. A float includes a magnet which activates or deactivates a switch. A vapor passage discharges the vapor from the cavity.Type: GrantFiled: August 1, 1990Date of Patent: November 19, 1991Assignee: Duracraft CorporationInventor: Bernard Chiu

Patent number: 5038394Abstract: A cordless thermal vaporizer of the liquid type wherein the body of the vaporizer has a heater for heating a wick for drawing up a chemical solution from a bottle, and a socket disposed under the heater and removably fittable in the form of a cap to the bottle for attachment thereto. The body is reduced in weight and thereby made attachable to an electric outlet with stability. The solution bottle can be attached directly to the socket of the body and is therefor easy to replace.Type: GrantFiled: October 6, 1989Date of Patent: August 6, 1991Assignee: Earth Chemical Co., Ltd.Inventors: Takahiro Hasegawa, Takanobu Kashihara, Junichiro Mesaki, Akira Nishimura

Patent number: 5014338Abstract: The components of an electric warm-air humidifier are enclosed in a housing. The components include an evaporation chamber in the shape of an inverted cup which has a steam outlet in its top and contains an electric heating element positioned at a short distance above its open bottom. The chamber bottom and the heating elements are immersed in water contained in the main compartment of an open, removable tray, having a smaller filling compartment communicating with the main compartment. The tray may be removed from the housing for cleaning. The neck of an inverted, removable jug filled with water is placed into the filling compartment, and water fills the tray until its level reaches the lower rim of the jug's neck. A blower is mounted above the evaporation chamber and delivers cool air through a duct which communicates with the evaporation chamber via its steam outlet, and humidified air is blown back into the room.Type: GrantFiled: December 21, 1988Date of Patent: May 7, 1991Inventor: Dov Z.
