A humidifying device for a vehicle has a humidity detection part, a blower, a non-water-supply humidifier, and a controller. The humidity detection part detects a humidity in a vehicle compartment. The blower draws, as an intake air, an inside air in the vehicle compartment and an outside air outside the vehicle compartment at a specified ratio and blows the intake air toward the vehicle compartment. The non-water-supply humidifier collects water included in the inside air and supplies a humidified air, which is humidified using the water, toward a specified area in the vehicle compartment. The controller sets the specified ratio between the inside air and the outside air and controls an operation of the non-water-supply humidifier. The controller controls the blower to draw at least the inside air, when the non-water-supply humidifier is operated, and when a humidity in the vehicle compartment is lower than a specified humidity.

A scrubber tower of a flue gas purification device, comprising: a flue gas entrance and a flue gas exit, a liquid entrance and a liquid exit, a contact area for said flue gas and said liquid between said flue gas entrance and said liquid entrance, at least one tray installation positioned within said contact area and across at least 50% of a horizontal extension of said contact area. The tray installation provides a multiplicity of through openings for said flue gas and said liquid respectively, which through openings being adjustable individually, in groups or all together in their respective cross sections.

An ultrasonic humidifier includes a tank having a water level and a floater having a tubular structure with a bottom rim and a top rim. The tubular structure has a frusto-conical shape and is vertically and co-axially disposed within the floater. The tubular structure having a widest diameter end disposed on the bottom rim and a narrower diameter end disposed at the top rim. This humidifier also has an air-supply arrangement that eliminates water damage to the fan during spillage.

Provided is a method for manufacturing a microbicide having high microbicidal performance for eradicating microbes. This method for manufacturing a microbicide comprises: a step for preparing an inorganic aqueous solution containing an inorganic component having seawater as a raw material thereof, an ozone mixing step for mixing ozone into the inorganic aqueous solution, and a stirring step for stirring the inorganic aqueous solution mixed with ozone and passing through a bubble generation nozzle; wherein, the temperature of the inorganic aqueous solution in the ozone mixing step and the stirring step is 0° C. to 30° C., and when the amount of inorganic aqueous solution treated in the ozone mixing step and the stirring step is defined as X liters and the treatment rate of the ozone mixing step and the stirring step is defined as Y liters/minute, then the microbicide is manufactured by alternately repeating the ozone mixing step and the stirring step for A.Math.X/Y minutes (where A is 30 or more).

Presented is a humidifier, comprising: a rotatable wick; a means for rotating the wick; characterized in that: the humidifier further comprises a disinfection unit adapted such that different parts of the wick are disinfected when the wick rotates.

An air conditioner includes a humidifying assembly and a control unit to control the humidifying assembly. The humidifying assembly includes a humidifying-receiving unit including a water tank configured to receive water and a humidifying-sterilizing unit configured to irradiate light to sterilize water received in the water tank. The control unit is configured to control a driving time of the humidifying-sterilizing unit based on an amount of water received in the water tank.

There is provided a mixing device (2) for a beverage and CO2 gas for producing carbonated beverage. The mixing device (2) having a mixing channel (4) extending in a main direction (10). The mixing channel (4) includes: wide channel sections (16) and narrow channel sections (18) along the main direction (10). The mixing channel (4) has an elongated cross section seen in a direction perpendicular to the main direction (10). At least a first delimiting surface (22) of the mixing channel (4) is provided with protrusions (20) extending at least partially along the first delimiting surface (22) in a direction across the mixing channel (4) and protruding towards a second delimiting surface (24) of the mixing channel (4) to form the narrow channel sections (18). A turbulent flow of beverage is created by the narrow and wide channel sections. Further a carbonator for producing carbonated beverage, an appliance having a carbonator, and a method of producing a carbonated beverage are provided.

Evaporator tray (100) for a sauna heater has one or more elongate plate members (102) extending across a support member (104). Support member (104) has at least two sides. In use, plate members (102) support rocks (not shown). Plate members (102) have a generally concave or hollow cross-section with a hollow face (106) upturned, which means they can collect unevaporated water, thereby protecting the sauna heater. The generally concave shape may be “V”-shaped, “U”-shaped, arcuate or concave, or any shape suitable for retaining water.

A filter arrangement for a humidifying device. The filter arrangement has: a rotatable body; a humidifying filter member arranged to be wetted with water; a guiding arrangement configured to guide water to a discharge region; and at least one discharge bucket arranged on the rotatable body. The at least one discharge bucket is configured to lift water from a tray and to discharge the water to the guiding arrangement as the rotatable body rotates in a first direction about a rotational axis. A humidifying device comprising a filter arrangement and a method for cleaning a humidifying filter member of a humidifying device are also provided.

A super-fine bubble generation apparatus includes a fine-array porous membrane and a device for generating substantially uniform, super-fine gas bubbles in a liquid. The fine-array porous membrane includes a plurality of pores having a substantially uniform size of <100 μm, with a variation of <20%. The super-fine gas bubbles generated by this apparatus can have a size of 50 nm-50000 nm, with a substantially uniform distribution with variations <20%. Applications of such super-fine bubble generation apparatus can include a skin cleansing device, or a teeth-cleaning device.
