Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to indoor air cleaning, and more particularly to a small air cleaner in which indoor air pollution sources are specified.

[0002]

2. Description of the Related Art FIG. 5 shows an ozone generator 4 which takes in indoor air with a blower 13 and removes dust with a filter 7.
1 is a schematic diagram showing the configuration of an example of an air purifier that aims to remove offensive odors, etc., but normally the indoor space in which the air to be purified is present has a much larger volume than the air purifier, and the air purifier purifies The room air to be blown naturally depends on the recirculation caused by the suction force of the blower 13. As described above, since the volume difference between the interior space of the air purifier and the indoor space is large, the clean air discharged into the room is diffused throughout the room, so the purified air is always targeted for the entire room.

[0003]

In the conventional structure as described above, the clean air that has been purified and discharged into the room through the discharge port immediately diffuses into the room where there is air before the cleaning, so that the installed air purifier is installed. The air to be purified that is to be acted on is the entire volume of the room. However, it is rare that dirty air or the like, which usually requires purification, emits a source to the entire room, and the source is generally limited. That is, it is inefficient in the purification of, for example, cigarette smoke, which requires partial purification, and in reality, the installation of a large air purifier is unavoidable in order to obtain the expected effect.

[0004]

A small air cleaner according to the present invention is provided with a housing provided with an outlet for purified air and an inlet for indoor air provided with a filter, and ozone provided therein. A generator, a rotating machine, an electric power source and a control device for driving them, and an air guide cover that is rotationally driven by the rotating machine and is provided so as to cover the air discharge port of the housing, A vane is formed on the inner wall of the guide cover, or a third indoor air intake port is provided on a base fixed to the bottom of the housing, and a plurality of legs are provided on the base to form a space under the base. It is configured as follows.

[0005]

[Operation] In the above configuration, a part of the air purified by the filter and the ozone generator is taken into the above-mentioned purification device again, and the source of air pollution that normally requires purification is limited, such as cigarette smoke. It does not require the installation of a large air purifier, etc., because it functions efficiently and can enhance the purifying action when purifying the air.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment according to the present invention, in which a base 2 serving as a base of the air cleaner body and a housing 1 fixed to the base 2 form an outer cover. And the ceiling part 1-1 of the housing
Has a hole 1-2 penetrating the output shaft 3-1 of the rotating machine 3, and an upper end of the cylindrical side wall 1-3 has an ozone generator 4 installed therein for removing deodorized and harmful substances. Flow passages A1-4 serving as discharge ports and flow passages B1-5 serving as intake ports for the room air to be purified are formed near the lower ends of the cylindrical side walls 1-3, respectively. A rotating machine 3 that drives an air guide cover 6 is mounted on the ceiling portion 1-1 of the housing 1, and dust is preliminarily collected from the air supplied to the ozone generator 4 installed inside the flow passage B1-5. A filter 7 is installed to remove it. Further, inside the casing, a power source and a control device 5 for controlling the operation of the rotating machine 3 and the ozone generator 4 are also arranged.

An air guide cover 6 is fixed to the end of the output shaft 3-1 of the rotating machine 3 protruding above the housing 1. As shown in the figure, the air guide cover 6 is provided so as to cover the flow paths A1-4 in the upper part of the housing, and is driven to rotate by the rotating machine 3 to take in indoor air into the air purifier. And a flow of air leading to the discharge from the inside is generated, and the air discharged from the flow paths A1-4 is provided in the lower flow path B.
In order to guide it to the vicinity of 1-5, a blade 6-1 having an axial inclination is formed on the inner wall thereof as shown in FIG. Incidentally, as a means for ensuring the reliability of fixing and holding the output shaft 3-1 of the rotating machine 3 and the air guide cover 6 and for facilitating the attachment and detachment at the time of maintenance, both fitting parts are made non-circular and the output shaft end is screwed. It is also good to fix it by tightening with the nut 10 after processing.

The room air to be purified is supplied from the flow passages B1-5 of the housing side walls 1-3 by the rotation of the blades 6-1 on the inner wall of the air guide cover 6 as shown by the arrows in FIG. It is taken into the air purifier through the filter 7,
Deodorization and removal of harmful substances are performed by the ozone generator 4 installed inside. Then, the purified air is once discharged to the outside of the housing from the flow path A1-4 of the housing as described above, but the discharged air is rotatably arranged so as to cover the flow path A1-4 as described above. Blades 6 on the inner wall of the air guide cover 6
1, a portion of the air purified by being pushed to the vicinity of the flow path B1-5 near the lower end of the housing side wall is again taken in from the flow path B1-5 together with the indoor air, and the purification of the filter 7 and the ozone generator 4 is performed. After passing through the device, the degree of purification will increase.

In the second embodiment, as shown in FIG. 2, legs 9 are provided on the base 2 to secure a space 11 under the base, and a flow path which is a third air intake port formed on the base 2 is formed. When the indoor air is taken in from C2-1, for example, when the ashtray 12 is placed in the space 11 under the table to take in the purple smoke, this tobacco smoke is purified in the air purifier and the flow path A is obtained.
Is once discharged from the outside to the outside, but by the blades 6-1 on the inner wall of the air guide cover 6 rotatably arranged so as to cover the flow passage A as described above, the flow passage near the lower end of the housing side walls 1-3 is formed. A part of the air purified by being pushed to the vicinity of B1-5 is taken in together with the indoor air from the flow path A, passes through the purification device of the filter 7 and the ozone generator 4, and the degree of purification is increased to the entire room. The effect of air pollution will be suppressed.

The filter 7 provided along the flow path B1-5 is detachably held by a holding member 8 together so as not to obstruct ventilation as shown as a housing portion in FIG. It goes without saying that they should be replaced as appropriate according to the progress of pollution.

As described above, the source of air pollution at a place where a small air cleaner is installed, such as an office space, is often specified, and the air to be purified by these specified sources is unconditionally specified. The aim is to increase the purification efficiency by carrying out repeated purification without diffusion.

[0012]

The small-sized air cleaner according to the present invention functions efficiently in purifying, for example, cigarette smoke, which usually has a limited source of air pollution that requires purification, and reduces the influence of the limited pollution source in the vicinity of the source. It is possible to limit the effect to a limited amount, and to bring about the effect that a large air cleaner is not required to be installed in order to enhance the cleaning effect.
