DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier, and more particularly, to a combination of an ultraviolet lamp and a discharge tube type ozone generator to enhance a sterilizing effect. The present invention relates to an air purifier that can prevent an excessive supply of ozone by holding a timer function for generating intermittently.

[0002]

2. Description of the Related Art In a conventional air purifier, pure air is supplied by filtering the sucked air, sterilizing it with ozone, and blowing it out into a room.

[0003]

However, in the conventional air purifier, the sterilization effect is low because sterilization is performed only by the discharge tube type ozone generator, and the discharge tube type ozone generator is energized and released. Therefore, there has been a problem that the discharge tube type ozone generator is overused unnecessarily, and the life of the discharge tube type ozone generator is shortened.

In the conventional air purifier,
Since the ozone for sterilization was released, the ozone contained in the indoor air became too rich. There is a problem that the vessel may be damaged.

The present invention relates to an air purifier for solving the above-mentioned conventional problems. The present invention relates to a combination of an ultraviolet lamp and a discharge tube type ozone generator to enhance the sterilizing effect and to improve the discharge tube type. An object of the present invention is to provide an air purifier that prevents an excessive supply of ozone by holding a timer function for generating ozone intermittently in an ozone generator.

[0006]

According to the present invention, a centrifugal sirocco fan is rotationally driven to suck air from a suction port at a lower portion of a casing, and primary filtered by a pre-filter, and two filters are arranged in parallel in two stages. UV-sterilized with a UV lamp, and second-filtered with a main filter, generate ozone with a discharge tube type ozone generator and sterilized again, and air that has been cleaned by these filtration and sterilization is passed through the upper outlet. The above-described problem has been solved by adopting a means in which the discharge tube type ozone generator has a timer function of intermittently generating ozone while blowing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a front perspective view showing a front panel of an air purifier of the present invention with a front panel removed.
An air suction port 2 is provided in the lower part on the front side of the air conditioner, and a pre-filter 3 is installed above the air suction port 2. Above the pre-filter 3, two ultraviolet lamps (hereinafter, referred to as UV lamps) 4a and 4b for emitting ultraviolet light are arranged in parallel in parallel at an interval in the vertical direction. A main filter 5 is arranged above the space 4b with an interval.

The air sucked from the suction port 2 is filtered by the pre-filter 3 for dust having a relatively large particle size, sterilized by the UV lamps 4a and 4b, and further filtered by the main filter 5 for the pre-filter. Dust of small particle size that has not been filtered by 3 is filtered. UV
The lamps 4a and 4b constantly irradiate the pre-filter 3 and the main filter 5 with ultraviolet rays to sterilize the equipment and the attached matter. A discharge tube ozone generator 6a is provided above the main filter 5, and the discharge tube ozone generator 6a further sterilizes the filtered and sterilized air.

A rotatable centrifugal sirocco fan 7 is provided above the discharge tube type ozone generator 6a, and an outlet 8 is formed in the casing 1 above the sirocco fan 7. When the sirocco fan 7 rotates, air containing dust is sucked into the casing 1 from the suction port 2, and the pre-filter 3, U
The air that has been filtered and sterilized by the V lamps 4a and 4b, the main filter 5, and the discharge tube type ozone generator 6a is discharged from the outlet 8 toward the room.

On one side of the casing 1, an ultraviolet ray generator panel 4 is provided, and on the other side of the casing 1, a power cord 9, a motor 10, and a discharge tube type ozone generator panel 6 with a timer are provided. Each is provided. The UV generator panel 4 on one side is the UV
The ultraviolet rays are generated by controlling the lamps 4a and 4b. The motor 10 on the other side rotates the sirocco fan 7, and the discharge tube type ozone generator panel 6 with a timer controls the generation of ozone of the discharge tube type ozone generator 6a by its timer function. And make it intermittent.

FIG. 2 is an explanatory view of a discharge tube type ozone generator panel with a timer according to the present invention. The discharge tube type ozone generator 6a has, for example, 30 units by the timer function of the discharge tube type ozone generator panel 6 with a timer. The ozone can be generated intermittently such that the circuit is turned on for only 5 minutes in a minute cycle and the others are turned off.
According to the present invention, since the discharge tube type ozone generator 6a does not perform redundant and unnecessary current supply and discharge as in the related art by generating the ozone intermittently, the ozone generation Can last longer.

Ozone is an allotrope of oxygen and is a gas having an odor like garlic, and sterilizes and purifies the air. However, dense ozone has the possibility of damaging the respiratory tract. Since the intermittent ozone generation according to the present invention suppresses the supply amount of ozone, the ozone content of room air can be appropriately reduced, eliminating the original garlic odor of ozone, In addition, the indoor environment can be maintained healthy and comfortable, for example, by eliminating the risk of violating the respiratory tract.

Next, the results of a test conducted by the Tokyo Metropolitan Institute of Public Health to prove the sterilization effect of the air purifier of the present invention are shown below. In this test, under the same conditions, a conventional air purifier without a fan and an air purifier of the present invention (with a fan) were operated to collect bacteria and fungi floating in the indoor air. Then, the number of floating bacteria per unit air was measured, and the bactericidal effect of the floating bacteria was determined.

The above test was conducted by the following method. In other words, an air purifier without a fan and the air purifier of the present invention are installed in the center of the room under the same conditions, and the bacteria are suspended in the air at a constant concentration. Bacillus subtilis (ATCC 6633 spores) diluted to a concentration was added, and the humidifier was operated to disperse the spore particles. On the other hand, by applying an impact to the tatami mats and walls of the Japanese-style room using a bedding, the attached fungi were released, and high-concentration floating fungi were scattered. Airborne bacteria were collected by aspirating room air at each elapsed time using an RCS air sampler (manufactured by Gunze Sangyo), an ABS air sampler (manufactured by Millipore) and a biochecker (manufactured by Nikken Biological). The discharge tube ozone generator of the air purifier of the present invention was turned on for only 5 minutes in a 30 minute cycle. Tables 1 to 4 show the test results.

From the test results shown in the above Tables 1 to 4, the air purifier of the present invention shows that indoor airborne bacteria (Bacillus subtilis spores) and airborne fungi (wet fungi, Fungi) proved to have a high bactericidal effect. In addition, the air purifier of the present invention sucked the indoor air with a sirocco fan and blows the purified air into the room, and as a result, it was found that the air purifier can be applied to a room as large as 40 tatami mats. .

[0020]

The present invention is embodied in the form described above, and has the following effects. The air purifier of the present invention can enhance the sterilizing effect by combining an ultraviolet lamp and a discharge tube type ozone generator. Further, since the discharge tube ozone generator with a timer of the air purifier of the present invention is configured to generate ozone intermittently, the life of the discharge tube ozone generator can be extended, and the running of the equipment can be performed. Cost can be reduced.
Furthermore, since the air purifier of the present invention generates ozone intermittently, it is possible to prevent the excessive supply of ozone to the room and to maintain the ozone concentration properly, and to eliminate the odor peculiar to ozone, and to improve the safety of respiratory organs. And the indoor environment can be maintained healthy and comfortable.
