Abstract

An air purification device includes an adsorption block, a housing, an introduction port for indoor air, an introduction port for heated air, a return port for indoor air, and a discharge port for used regeneration air. The adsorption block adsorbs purification target substances in indoor air, and is regenerated by dispersing the adsorbed purification target substances by circulating heated air. The housing accommodates the adsorption block therein. The introduction port for indoor air and the introduction port for heated air are provided on one end side of the housing. The return port for indoor air and the discharge port for used regeneration air are provided on the other end side of the housing. An insulating layer is provided between the housing and an outer surface of the adsorption block.

First claim

What is claimed is:

1 . An air purification device comprising:
an adsorption block configured to adsorb purification target substances in air by indoor air being circulated, and which is regenerated by dispersing the adsorbed purification target substances by circulating heated air; a housing configured to accommodate the adsorption block therein; an introduction port for indoor air and an introduction port for heated air provided on one end side of the housing; and a return port for indoor air and a discharge port for used regeneration air provided on the other end side of the housing, wherein the air purification device being switchable between an air purification state in which the introduction port for indoor air and the return port for indoor air are able to communicate with the adsorption block and a regeneration state in which the introduction port for heated air and the discharge port for used regeneration air are able to communicate with the adsorption block, and an insulating layer is provided between the housing and the outer surface of the adsorption block.

2 . The air purification device according to claim 1 , wherein the housing comprises a partition wall configured to partition the inside thereof into a plurality of accommodating chambers,
an adsorption block is disposed in each of the accommodating chambers, and the adsorption block in each of the accommodating chambers are made switchable between the air purification state and the regeneration state.

3 . The air purification device according to claim 1 , wherein the insulating layer is constituted by a hollow chamber provided to seal between the housing and the adsorption block.

4 . The air purification device according to claim 3 , wherein a space between a circumferential edge of an air introduction-side end portion of the adsorption block and the housing is sealed by a first seal section, and a space between a circumferential edge of an air discharge-side end portion the adsorption block and the housing is sealed by a second seal section.

5 . The air purification device according to claim 4 , wherein a support protrusion disposed between the first seal section and the second seal section and in contact with the outer surface of the adsorption block is provided on the inner surface of the housing.

6 . The air purification device according to claim 5 , wherein a tip of the support protrusion is formed in a hemi-spherical shape.
