With respect to atmospheric steam generating humidifiers, the present disclosure resolves the problem of end-users not adjusting the drain interval of the humidifier by using an electronic controller to automatically choose an appropriate drain interval without requiring any user input. The electronic controller accomplishes this by receiving input data from a sensor that measures a water quality parameter, automatically determining a drain interval based on the received data, and sending an output control signal to a drain water control valve to execute a drain event in accordance with the drain interval. In some examples, the electronic controller utilizes a look-up table correlating the water quality parameter to a total dissolved solids or cycles of concentration value.

This application relates to a humidifying device, including a shell, an air duct and an air blowing apparatus disposed in the shell, wherein a mist outlet channel, an atomizing cavity and a heating cavity communicated with the mist outlet channel are disposed in the shell; the air duct includes a first air duct communicated with the atomizing cavity and a second air duct communicated with the heating cavity; the air blowing apparatus is provided with an air outlet member, and the air outlet member is aligned with the first air duct and the second air duct, and is configured to supply a first air flow to the first air duct and supply a second air flow to the second air duct. When the humidifying device operates, the first air flow forms an atomized air flow and the second air flow forms a heated air flow then are mixed.

Steam cylinders for humidifies require periodic replacement as well as replacement to address failures etc. However, field replacement of steam cylinders is not a straight-forward operation and there is significant risk and potential for damage to the replacement cylinder and the humidifier as fluidic seals for the water inlet and steam outlet must be unmade as well as electrical connections for heater elements, level sensors etc. Accordingly, embodiments of the invention provide solutions for the deployment of replacement cylinders etc. for domestic, retail, and commercial systems that reduce the likelihood of damage to the fluidic seals, electrical connectors etc.

The electrical connections of a chamber or enclosure for a water tub can be protected through the use of spill element sensors. The spill element sensors can help to disable the delivery of power to the heater of a water tub in the event that the electrical connections become wet.

Liquid heating devices and methods of use are disclosed herein. In some embodiments, devices include a heating element and a surface area interactive material contacting the heating element, the surface area interactive material having approximately zero surface tension interaction with a liquid which is passed through the surface area interactive material, the surface area interactive material conducting heat from the heating element into the liquid to raise a temperature of the liquid.

A humidifier that suppresses formation of a slime, a scale, and a dew bridge in a lower portion of a humidifying member thereby preventing degradation in humidifying performance. The humidifier includes one or more porous metal bodies serving as the humidifying member and including therein a plurality of voids, a fan that blows air to the porous metal body, a water-supplying device (a supply pipe, a reservoir, and a nozzle) that supplies water to the porous metal body, and the porous metal body includes a tip portion formed in a lower end portion, in a protruding shape or a pointed shape.

A humidifier includes a second housing. A water storage tank is in a housing space of the second housing. The tank is detachable through an attachment/detachment port of the second housing. A third introduction hole communicates an inside and an outside of the second housing with each other in the second housing. A first tank hole communicates an inside and an outside of the tank with each other in the tank. Between the second housing and the tank, a first seal member separates a first downstream side flow path leading to an inside of the tank through the third introduction hole and the first tank hole, from an external space of the second housing. The first seal member extends along an inner surface of the second housing to entirely surround the tank, when viewed from a top of the tank.

Methods and apparatus for vaporizing liquid from a liquid source into the surrounding environment, are disclosed, where the apparatus comprises at least one manifold comprising at least one liquid port formed by a through-hole and at least one ridge structure, wherein the liquid port is in fluid communication with the liquid source and the one ridge structure At least one vaporization port is included in a planar structure connecting a first side of the structure to a second side, in fluid communication with the at least one ridge structure and the surrounding environment, wherein fluid flow through the liquid and vaporization ports is substantially perpendicular to the plane of the structure, and the ridge structures are substantially parallel to the plane of the structure. At least one heating element is present that is in thermal communication to the at least one vaporization port and at least one ridge structure.

The electrical connections of a chamber or enclosure for a water tub can be protected through the use of spill element sensors. The spill element sensors can help to disable the delivery of power to the heater of a water tub in the event that the electrical connections become wet.

Provided are an indoor unit of an air conditioner and a method for controlling the same, the air conditioner includes a humidification module to generate steam, mix the generated steam with filtered air to generate humidified air, and spray the humidified air at a discharge outlet through an independent flow path to provide the humidified air to an indoor space, in a smart care mode, performs a humidification operation during a heating operation to discharge the humidified air together with heat-exchanged air, automatically switches a mode between a high speed mode and a comfortable mode to prevent frequent on and off, thereby saving energy, and automatically switches an operation mode thereof according to a temperature and humidity to control discharged air and the humidified air, thereby effectively supplying air with adjusted temperature and humidity.
