The present disclosure provides a humidifying device, including: a container, configured to accommodate a liquid; a first moisture absorptive member, partially or completely dipped in the liquid in the container; a second moisture absorptive member with air permeability, in contact with or isolated from the first moisture absorptive member; and a driving member, configured to control movement of the second moisture absorptive member, so as to allow the second moisture absorptive member to be in contact with or isolated from the first moisture absorptive member. The humidifying device according to the present disclosure can be applied in household appliances such as air cleaners and air conditioners. The operation and shut down of the humidification function is controlled, so as to avoid formation of superfluous air resistance when the humidification function is shut down. The present disclosure further provides an air cleaner and a household appliance, including the humidifying device provided according to the present disclosure. The air cleaner and the household appliance are not only simple in structure, effective in cost, and convenient in installation, but are also quiet when in operation.

A system that provides effective and efficient introduction of water droplets into an air flow. The water droplets are sufficiently small so as to evaporate primarily before leaving the mixing enclosure where the droplets are injected by spray nozzles. Large droplets are kept to a minimum, thus reducing condensation and water accumulation to a very small amount. An amount of water usage is significantly less than that of a conventional evaporative humidifier of the same capacity. The present system may be placed in an enclosure that can readily replace other conventional evaporative humidifiers in enclosures. The present enclosure and system may be installed in lieu of a conventional enclosure and evaporative humidifier with minimal effort. The present enclosure has features that facilitate droplet to air mixing, viewing, humidification, and testing. In permissible situations, the present system may replace a conventional system but retain the conventional enclosure.

A humidifier includes a housing, a water reservoir configured to hold a quantity of water, a fan assembly configured to generate an air flow path within the humidifier, a sanitizing system, and a wick assembly. The sanitizing system is configured to generate a sanitizing gas and to transfer the sanitizing gas to the water reservoir such that at least a portion of the sanitizing gas is absorbed into the water in the water reservoir. The wick assembly is fluidly configured to receive water from the water reservoir and transfer the water into the air flow path to generate humidified air. The water received by the wick assembly includes at least a portion of the sanitizing gas absorbed into the water, wherein at least a portion of the water received by wick assembly flows back to the water reservoir.

Disclosed is a humidifier having multiple water pans stacked together with one water pan at the top of the stack and one water pan at the bottom of the stack and the remainder water pans in the middle of the stack; within each water pan, there are evaporate pads comprised of multiple layers and positioned in sequences like wave after wave. Water fills the water pan at the top the stack and continues to fill the water pans in the middle of the stack one by one and then the water pan at the bottom of the stack; in doing so, water moistens the evaporator pads within each water pan, while warm air moves through the evaporator pads, warm air absorbs moisture to create humidified air.

It is an Evaporative Humidifier Air Purification combo unit performing the functions of both cool mist evaporative air humidifier as well as the air purifier. The optional attachments make it easy for the consumers to make use of any of the functions it is capable of performing. It even solves the problem of degradation of performance and material life prevalent in conventional standalone air purifier units. The evaporative humidifier is motor driven and is provided with proprietary HEPA quality nano membrane with high chemical stability, waterproof, water vapor permeability, windproof, breathable, acid and alkali resistant, anti-corrosion and anti-bacteria functions etc. membrane used in combination with humidifier cooler pads. On using the water tank, the setup performs the function of air humidifier using the air sucked from the wick using the fan and aiding the evaporation of water in the tank. While on replacing the water tank with the air cover, the same fan sucks air through wick and blows the purified air upwards in consonance to the mode i.e. High, Medium or Low.

Various embodiments for a drip irrigation system configured to control a temperature of at least a portion of a synthetic playing field are described. A system may include a synthetic surface and a drip irrigation system that provides water to one or more portions of the synthetic surface. The drip irrigation tubes include water outlets positioned relative to the synthetic surface such that synthetic fibers wick moisture from the water outlets. A pump may be fluidly coupled to plurality of irrigation tubes and a controller may be configured to cause the pump to drive fluid through the irrigation tubes at a controlled rate to provide heat management in at least a portion of the synthetic surface.

Disclosed are a humidifier and a household appliance. The humidifier includes a housing, a fan, a water absorption net assembly and a time record assembly. The housing is provided with an air inlet and an air outlet, an air duct communicating with the air inlet and the air outlet, and a water storage tank communicating with the air duct are formed inside the housing. The fan is provided in the air duct. The water absorption net assembly is at least partially extending into the water storage tank and at least partially extending into the air duct. The time record assembly is installed in the housing and configured to record a use time of the water absorption net assembly.

Disclosed is a powerless humidification module for an air cleaner which is capable of preventing leakage of water into the air cleaner. A powerless humidification module for an air cleaner which is detachably mounted on an upper portion of a body of the air cleaner and is capable of preventing leakage of water includes a base cover having a first opening opened toward the air cleaner and a second opening opened toward a side surface of the first opening, a cistern part located in the interior of the base cover and located such that a space defined between an inner partition wall and an outer partition wall having predetermined heights such that water supplied to one side thereof is stored surrounds a periphery of the first opening whereby water supplied to one side thereof is stored, and a humidification filter located in the second opening.

Evaporative humidifiers comprising: in vertical relationship and fluid communication with each other, a water inlet and a water reservoir downstream therefrom, positioned to receive water along a first fluid path; air inlet(s) and air outlet(s) in vertical relationship with the water inlet and/or reservoir, and a wick, downstream the water inlet, partially disposed in the reservoir to draw water therefrom to a wick portion in fluid communication with the air inlet(s) and the air outlet(s); and a motor-fan assembly downstream and in vertical relationship with the water inlet, upstream the reservoir. The reservoir and one or more of the air inlet(s) and the air outlet(s) generate an air current for drawing air, via the air inlet(s), from an external environment through the wick portion and move moistened air to the external environment via the air outlet(s) along a second fluid path at least partially separate from the first fluid path.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source through an inverse-opal wicking structure to a vaporization port where the vaporization port is formed by a through-hole in a structure connecting a first side of the structure to a second side, with all dimensions ranging from 10 um to 300 um, that is in fluid communication with the liquid source and the surrounding environment so that fluid is transported through the vaporization port between the first and the second side.
