Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deodorizing filter used for deodorizing various offensive odors contained in indoor air.

[0002]

[Prior Art]

 Various offensive odors are contained in the air in the room of homes and the rooms of various business sites. The effects of these offensive odors on the human body and substances cannot be overlooked, and various air purifiers have been proposed so far. Focusing on the fact that water itself has a deodorizing effect, the water was retained in an air purifier and the air before deodorization was made to pass along this water surface for deodorization. There is something. This device is widely used because it does not require a complicated mechanism and can be produced at low cost.

[0003]

[Problems to be solved by the device]

 However, since the above-mentioned conventional example only takes in air on the water surface and allows it to pass therethrough, a unit amount of air can contact the water surface for an extremely short time. Therefore, the time during which the air can be deodorized by water is extremely short, and the deodorizing effect is small. On the other hand, by controlling the flow of air, it is possible to extend the time to touch the water surface, or to touch the water surface multiple times and then go out of the equipment. However, this will increase complexity and cost.

The present invention is proposed to solve such a problem, and an object thereof is to provide a deodorizing filter capable of efficiently deodorizing air with a simple device.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention provides a deodorizing unit member which is a plate-like member formed of a water-absorbing material and having a bent portion. It is characterized in that a plurality of deodorizing air passing therethrough are arranged side by side with a required gap, and pass through between the deodorizing unit members while repeatedly colliding and reflecting on the wall surface forming the deodorizing unit member. It is used as a deodorizing filter.

[0006]

[Action]

 With this structure, the pre-deodorizing air is discharged after the deodorizing unit member has been touched for a long time, and thus is discharged after being sufficiently deodorized.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a partial outline of a deodorizing device using the filter of the present invention. The filter 1 has a sucking tongue 3 which is soaked in a liquid tank 2 and sucks up the liquid. The liquid sucked up through the sucking tongue-shaped piece 3 efficiently permeates the entire deodorizing unit member forming the filter 1. Therefore, it is needless to say that the member forming the filter 1 has a water-absorbing property and is easily wettable. Needless to say, various materials having such properties have been developed so far. Can be selected and used.

As the liquid contained in the liquid tank 2 and absorbed by the filter 1, various kinds of synthetic water such as water may be used. For example, synthetic water is one in which manganese and vitamin C are combined and dissolved. This has the effect of suppressing the reproduction of harmful microorganisms and has a unique deodorizing effect. The liquid infiltrated into the filter 1 is formed so that the malodorous substance in the air is deodorized by a chemical change to become odorless air, and then the components in the liquid return to the original components. Therefore, after the deodorizing action of the filter 1, there is no possibility that adhered substances will remain and maintenance is not required, so that the filter 1 can be repeatedly used for a long period of time.

The clean air deodorized by the filter 1 is discharged outside the device by a fan 5 driven by a motor 4. The deodorizing device having such a device main part may be combined with other essential members in the form of an air purifier according to the application. Hereinafter, the deodorizing filter 1 will be described in detail.

FIG. 2 shows a first embodiment of the filter according to the present invention. The unit member 6 for deodorization has one bent portion 7 and has a V-shaped folding screen shape in a plan view. A plurality of the deodorizing unit members 6 are arranged side by side in the same direction, and the deodorizing unit members are connected to each other by a connecting member (not shown). Further, the suction tongue 3 is provided on any of the deodorizing unit members 6 or on the connecting member (not shown). The sucking tongue-shaped piece 3 is partially immersed in the liquid tank 2 so as to suck the liquid and infiltrate the deodorizing unit members 6 with the liquid.

The filter 1 is held by the holding frame 8 and has a predetermined shape, but the air flow before deodorizing enters the wall surface of each deodorizing unit member 6 as indicated by the arrow, and enters the wall surface. It passes between the deodorizing unit members 6 while being reflected by. Therefore, as compared with a state where the deodorizing unit members 6 having no bending portion pass in parallel to the surface of the deodorizing unit member 6, air is forced on the surface of the deodorizing unit member 6 for a long time. It will pass through without contact.

As described above, the air is chemically deodorized by the liquid infiltrating the deodorizing unit member 6 and is then discharged as odorless air. As described above, the liquid does not leave an adhered substance on the deodorizing unit member 6 even if the air is deodorized, so that it can be continuously used. Therefore, as long as the required liquid is replenished in the liquid tank 2, it is possible to continuously deodorize the air without requiring special maintenance management.

FIG. 3 shows a second embodiment of the present invention (the parts corresponding to those of the first embodiment are designated by the same reference numerals. The same applies to the following embodiments). It is a plan view. In this embodiment, a plurality of bending portions 7 of the deodorizing unit member 6 are provided. With such a configuration, the air passing through the filter 1 hits the surface of the deodorizing unit member 6 before passing through the filter 1, the number of times of reflection is increased, and the deodorizing effect can be increased. Since the resistance to the air passing through a large number of the bent portions 7 becomes large, it may be necessary to increase the air pressure to be passed in the case of such a structure.

FIG. 4 shows a third embodiment of the present invention, in which a resistance piece 9 is attached to the wall surface of the deodorizing unit member 6. Moreover, since resistance pieces 9 are provided on both sides of the air passage formed by the deodorizing unit members 6 in the passage direction, the resistance against the passing air becomes extremely large. With this configuration, when the air passes, the air strikes the deodorizing unit member 6 and, in addition to being reflected, creates a vortex in the air passage, so that the air makes more contact with the deodorizing unit member 6. Like It should be noted that the resistance piece 9 should be made of material selected so that it will float around the attachment point as a fulcrum when passing air, or if it is attached, it will avoid increasing the resistance against passing air more than necessary. Be done. Further, the mounting of the resistance piece 9 in the height direction may be changed for each deodorizing unit member 6, or may be any configuration such as mounting the resistance piece 9 in the entire height direction.

FIG. 5 shows a fourth embodiment of the present invention, which should be called a modification of the third embodiment. In this embodiment, the resistance piece 9 attached to the wall surface of the deodorizing unit member 6 is provided only on one side of the air passage. Moreover, unlike the third embodiment, the angle at which the resistance piece 9 is attached is 90 ° with respect to the wall surface. With this configuration, the eddy current when air passes can be generated by the minimum resistance piece 9. Therefore, the cost can be reduced when the filter 1 having the resistance piece 9 is produced.

The present invention is not limited to the above embodiments, but various modifications and variations are possible. For example, the shape of the filter may be a gentle curve even if the bent portion is not an acute angle, and the intervals between the deodorizing unit members may not be equal intervals. Moreover, if a removable dustproof filter is attached to the air introduction side of the filter, the filter can be protected together with other dustproof filters provided in the device. Further, it is needless to say that the present invention is not limited to the arrangement as shown in FIG. 1 and can be appropriately arranged according to the specific mode of the air cleaner.

[Effect of the device]

 As described above, according to the present invention, by efficiently contacting the air with the surface of the deodorizing unit member, it is possible to efficiently deodorize through the liquid infiltrated into the deodorizing unit member. Moreover, since there is no need for maintenance and maintenance, and no problems with durability are caused, odors such as ammonia, trimethylamine, sulfur compounds, and mercaptans can be easily and properly deodorized.
