[Conventional technology and problems]

2. Description of the Related Art In recent years, opportunities to eat while cooking on a cooking table have increased indoors, and cooking utensils such as cooking tables and simple hot plates have become commonplace in homes. However, when eating while cooking in this way, smoke (particularly oily smoke) and odors are generated and fill the room, which can even spoil the atmosphere of the meal. In addition, there is a problem that these smoke and odors adhere to furniture, curtains, walls, etc.

There was a desire to develop a small and inexpensive air purifier.

In order to satisfy this need, air purifiers placed on the cooking table and ventilation fans placed on the walls of the room have been proposed, but the former air purifiers do not have sufficient cleaning ability. Furthermore, in the case of a ventilation fan, the above requirements cannot be met.

Therefore, the inventors of the present invention conducted intensive research to solve the problems of the conventional techniques as described above, and as a result of various systematic experiments, they came up with the present invention.

An object of the present invention is to provide an air cleaner that is excellent in adsorbing and deodorizing properties such as oil smoke and irritating odors.

[Structure of the invention]

The air purifier of the present invention is a mobile type air purifier that is installed indoors and includes a blower, a housing having an opening in an air passage, and an adsorption deodorizing section disposed between the blower and the opening. The adsorption/deodorization section is characterized by having an adsorption layer containing a hydrous magnesium silicate clay mineral as a main component.

The configuration of the present invention will be explained in more detail below.

The adsorption/deodorization unit in the present invention absorbs oily smoke-like substances such as oily smoke and bad odors that pass through the air passage of the indoor purifier.

It is intended to adsorb and absorb irritating gaseous substances such as foreign odors, and has an adsorption layer mainly composed of a hydrous magnesium silicate clay mineral on at least a portion of the opening of the blower and the housing.

Obtain an aqueous dispersion of clay minerals.

Next, a valve as a binder and aluminum sulfate as an additive are added to this aqueous dispersion of clay minerals, and the mixture is mixed and dispersed. Furthermore, a synthetic emulsion or the like as a binder is added and mixed until it is sufficiently dispersed, and then a paper is made by a paper making method and dried to form a sheet-like adsorption sheet. In addition, after simply defibrating the clay mineral raw stone and dividing it into short fibers,
An adsorption sheet may be obtained by mixing water and a small amount of a binder, such as SBR (styrene butadiene rubber), cornstarch, a glue material such as PVA, or a valve, using a mold, and drying the mixture. Next, desired air permeability is imparted to this adsorption sheet by press machining or the like.

Here, in order to increase the strength of this adsorption sheet, a mixture of at least one of a valve, a chemically synthesized fiber, an inorganic fiber, a metal fiber, etc. may be used in addition to the clay mineral.

In addition, when using two granular clay minerals, granular clay minerals obtained by crushing clay minerals as raw materials or powdered clay minerals can be used as fillers such as kaolin and silica sand, styrene-butadiene rubber latex, acrylonitrile butene, etc. Synthetic organic binders such as rubber latex, polyurethane, and melamine; natural organic binders such as cellulose and natural rubber latex.

Additives such as inorganic binders such as aluminum sulfate are added as appropriate, and granular clay minerals obtained by granulating and drying to an appropriate size are used, and these are inserted into a case with air permeability to form an adsorption layer. Here, the case having 2 air permeability consists of a frame body made of metal, ceramics, 2 synthetic resin, wood, etc., and an air permeable sheet provided in the air passage portion of the case. This breathable sheet can be made of paper such as Japanese paper, 9 synthetic resin, cloth such as cotton, carbon fiber 1 synthetic resin fiber, or organic.

Use one made of inorganic fibers.

In addition, when using powdered clay minerals, the appropriate shape is made of metal or ceramic that has air permeability.

A case body made of synthetic resin or wood is sprayed with a mixture of clay minerals and a binder.

Furthermore, in order to further increase the adsorption capacity of these adsorption layers,
A mixture of clay minerals and adsorbents such as activated carbon and zeolite activated clay may also be used.

Here, this adsorption/deodorization part may be composed only of an adsorption layer mainly composed of the above-mentioned clay mineral, but in order to effectively adsorb and absorb dust, smoke, odors, etc., it is mainly used for dust, etc. It is preferable to have a structure consisting of a first adsorption layer that adsorbs smoke and odors, and a second adsorption layer that mainly adsorbs and absorbs smoke and odors.

A specific example of the configuration is as follows. This adsorption/deodorization section 1 has a structure in which a first adsorption layer 2 and a second adsorption layer 3 are simply arranged in parallel, as shown in a conceptual diagram in FIG. In this case, the first adsorption layer 2 is.
