Abstract

PURPOSE:To form a compact air purifier for a household use and car loading use, by providing a suction port having a blower device mounted therein, a main body case having a blowoff port and a fiter, which is formed by pleating filter paper in a zigzag pattern and receives a deodorant in the recessed part thereof, provided to the suction port. CONSTITUTION:A main body case 1 has a blow-in port, which is formed of a freely detachable grill 2, provided to the entire front surface thereof and has a blowoff port 5, which is formed of a grating 4, provided to a part of the upper surface thereof. Within the main body case 1, a filter block 9 is provided to the suction port 3 and a fan 10 is provided behind said filter block to be attached to a motor 11. The filter block 9 is constituted by providing a dust removing partition wall formed by pleating filter paper in a zigzag pattern in a filter frame 20 and filling the recessed parts provided to both sides of the partition wall 17 with deodorants 18, 19.

Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to an air cleaner for home use and the like.

[Background technology]

BACKGROUND ART Conventionally, in general, air cleaners use a dust removal filter and a deodorizing filter that performs all functions such as gas adsorption. The dust removal filter has a sieving effect and is made of pleated paper. Granular activated carbon is often used for deodorizing filters, and other materials such as porous bodies impregnated with chemical substances are also used.

In order to construct a filter unit 7 using these, each is formed into a box or a container shape and stacked on top of each other in a box shape. As a result, the filter unit becomes large, which poses a problem, especially in air cleaners for home use, vehicles, etc., which require thinness and compactness.

In addition, activated carbon is the mainstream deodorant, but it is not a panacea.
It is effective to use other types of deodorizers (eg, neutralizers) in combination.

In some cases, these two types of granular deodorants can be simply mixed together, but their effectiveness may be reduced if they come into direct contact with LC, or they may have different specific gravity, so they may be separated if they are simply mixed. There are things etc. However, if the deodorizing filter is further divided into multiple layers, it will become even more bulky.

[Purpose of the invention]

The overall purpose of the present invention is to provide an air cleaner that can be made thin and compact and suitable for home use, vehicle use, etc.

[Disclosure of the invention]

The air purifier of the present invention uses a filter in which a deodorant is housed in four parts of a partition wall made by folding filter paper in a zigzag shape.

Embodiment 'f of this invention: @8 shown in Figures 8 to 3
In the figure, ■ is the main body case, and the entire air surface V
It has an entire suction port 3 formed by a removable grille 2, and a blowout port 5 formed by a lattice 4 on a part of the upper surface. The upper surface of the main body case 1 is inclined forward. The main body case 1 is to be placed vertically for stationary use, or upside down for hanging installation, and has a push button switch for stationary use.
A sochi 6 and a pull swivel for hanging use are provided on the top surface. 8 is a timer 2 A suction port 31C and a filter block 9 are provided in the main body case 1, followed by an IC centrifugal fan 1o. The centrifugal fan 1o is attached to the motor 11, and the motor 1
1 is fixed to the main body case IK with a bolt 13 together with a wall hanging tool 12. 14 is a cavity 1 that accommodates a centrifugal 7 ampere 10
5, the bellmouth-shaped middle plate suction port 1
It has 4a.

A safety grid 16 is provided integrally with the middle plate 14 at the middle plate suction port 14a. Moreover, a filter fitting wall 14b is integrally provided on the middle plate 14.

The filter block 9 is provided within the filter frame 20 through a partition wall 171i for dust removal made by folding filter paper in a zigzag shape, and is filled with deodorizers 18 and 19a in four parts on both sides of the partition wall 170. is covered with a breathable mesh sheet 21.

The deodorants 18 and 19 are each in the form of granules or coarse powder, and the deodorant 18 on the front side of the partition wall 17 and the deodorant 1 on the back side of the partition wall 17
A different type from 9 is used.

For example, activated carbon is used for the deodorant 18 on the front side, and an inorganic adsorbent such as zeolite is used for the deodorant 19 on the back side.

In this way, since the deodorant 18.19 is filled in the recessed part of the partition wall 17 with a zigzag shape, the thickness of the partition wall 17, which is an element for dust removal, can accommodate the deodorant 18.19, making it thin. This makes it a compact Filter Pro 9. Therefore, the overall shape of this air cleaner can also be made thinner. !
2N deodorant 18.19? However, since they are placed separately on the front and back of the partition wall 17,
If these two types of deodorants 18, 19 are mixed, there is no problem even if they are inconvenient. When the activated carbon (specific gravity 0.5) used as the front side deodorant 18 and the zeophyte (specific gravity 2.0) used as the back side deodorizer 19 are mixed, uneven mixing will occur due to the difference in specific gravity. However, in this way, the partition wall 17
By arranging them separately on the front and back sides, uniform deodorization can be achieved over the entire filter block 9.

Note that the deodorants 18 and 19 do not necessarily have to be provided on both sides of the partition wall, and it is also possible to provide one type of deodorant only on one side.

〔Effect of the invention〕

The air purifier of this invention can be made thin and compact, making it suitable for home use and vehicle installation.
