Water-permeable resin members for adding water to gas
A recently granted patent (Publication Number: US11649972B2) describes a gas conditioner designed to add water to a gas. The gas conditioner consists of a case that forms a gas channel and a resin member with water permeability, which is placed within the gas channel. The resin member is made up of multiple resin members and is supported by a support structure that allows for attachment and detachment.
Claim 1 of the patent highlights the key components of the gas conditioner, including the case, resin member, and support structure. The resin member is described as a hermetic hollow material that encloses water. This claim emphasizes the modular nature of the resin member, which can be easily attached or detached from the support structure.
Claim 2 provides additional details about the structure of the resin member. It mentions that the resin member consists of a tubular peripheral wall portion and a closing portion that seals each end of the peripheral wall. The closing portion is formed through the welding of a resin material.
Claim 3 specifies that the resin member has a helical shape, indicating a spiral or coil-like structure. This design feature may enhance the water permeability and distribution within the gas channel.
Claim 4 states that the case, which forms the gas channel, is made of a metal material. It further mentions that the gas conditioner is intended for use in an air conditioning space where the air temperature is adjusted.
Claims 5 to 9 reiterate and combine various aspects mentioned in the previous claims. They highlight the use of a hermetic hollow resin member, the tubular peripheral wall portion with a welded closing portion, the helical shape of the resin member, and the case made of a metal material for use in an air conditioning space.
Overall, this granted patent describes a gas conditioner that utilizes a modular resin member with water permeability to add water to a gas. The design allows for easy attachment and detachment of the resin member, and the use of a helical shape may enhance water distribution. The gas conditioner is intended for use in air conditioning spaces where the air temperature is adjusted.
