As disclosed in the above prior art, in order to sterilize air, ultraviolet rays emitted from ultraviolet lamps, titanium dioxide photocatalysts to promote the sterilization of ultraviolet rays, anions generated from anion generators to promote decomposition of harmful substances, and the like are used. Both are effective elements for sterilization.

However, the above-mentioned prior art is mostly equipped with a plurality of ultraviolet lamps (UV) inside the moving passage of the air having a predetermined cross-sectional space of the air to the ultraviolet irradiation area (照射 領 域) is emitted by the moving means of the air (照射 領 域) Is sterilized by forcibly moving it, but the air passes through the ultraviolet irradiation area momentarily, so the amount of ultraviolet radiation irradiated into the air is insufficient, so it is difficult to expect the air sterilization effect.

In particular, the filter unit of the air cleaner is the place where bacteria suspended in the air during the filtration process have the highest adhesion density of bacteria through the various dust attached to the filter, and bacteria propagation by water and organic dust is also active. There was a problem of insufficient sterilization of the filter mechanism.

In addition, when operating the air sterilizer in the hospital room, there is a problem that the noise in the environment of the hospital room to be quiet, especially since the operating noise of the motor fan is severe at night.

The present invention is divided into the dust chamber and the sterilization chamber in the side of the air exhaust chamber of the air purifier body forward and backward to provide an air inlet and a filter mechanism on the door of the dust chamber, the sterilization provided on the wall surface of the dust chamber facing the front when the door is closed During the dust collection process, the bacteria are continuously sterilized by the filter mechanism by focusing on bacteria with high adhesion density. Then, the air passes through the sterilization chamber having the aluminum light reflecting surface coated with the photocatalyst by natural convection of the air. New air purifiers have been developed to increase UV sterilization effect by increasing the time.

An object of the present invention is to provide an air purifier with improved dust collection and sterilization of air

Another object of the present invention is to partition the dust collection chamber and the sterilization chamber back and forth with the diaphragm of the exhaust chamber of the main body of the air purifier to the back and forth to each of the dust collection chamber and the sterilization chamber to open and close the door and the air in the door of the dust collection chamber When the door is closed with the inlet and the filter mechanism, the sterilization lamp provided on the wall surface of the dust chamber facing the front face sterilizes the bacteria with high adhesion density through the filter mechanism through the dust, etc. Provides an air purifier that gently sterilizes the sterilization chamber with a photocatalyst coated aluminum light reflection surface by natural convection, and is sterilized strongly by sterilization lamps provided on the wall to supply clean air. It is.

Another object of the present invention is to open the door provided in the dust collecting chamber and the sterilization chamber of the main body can be easily cleaned deep inside the dust collecting chamber and sterilization chamber, the bacteria can be attached to remove the factors to breed hygienic air To provide a purifier.

Another object of the present invention is to provide an air purifier that can be safely used in a quiet place without operating noise during use of the air purifier.

The present invention provides an air purifier, wherein an exhaust chamber of air is provided on one side of a space of a rectangular parallelepiped body, and a dust collecting chamber and a sterilization chamber are partitioned back and forth by a diaphragm on the side of the exhaust chamber, and air is vented below the one side of the diaphragm. It is provided. The dust collection chamber and the sterilization chamber are each provided with an openable door, and the door of the sterilization chamber is provided with an air inlet and a conventional composite filter mechanism. A plurality of sterilization lamps are provided on the wall surface of the dust chamber facing the door, and ultraviolet rays emitted from the sterilization lamps are continuously irradiated to the filter mechanism to concentrate various bacteria having high adhesion density through the dust adsorbed to the filter mechanism during the filtration of air. It is supposed to be sterilized.

A vertical diaphragm that divides the passage in a zigzag section is provided in the middle of the sterilization chamber through which the air of the dust collecting chamber is introduced through a through hole provided at one side of the diaphragm, with an air vent at the upper side thereof. Sterilization lamps are provided.

The wall surfaces of the dust collection chamber and the sterilization chamber are aluminum light reflecting surfaces coated with a photocatalyst to prevent the ultraviolet rays emitted from the sterilization lamp from being absorbed from the walls and to enhance the sterilization function by the reflection of the ultraviolet rays.

The upper side of the exhaust chamber communicating with the sterilization chamber is provided with the exhaust pipe relatively high vertically like communication, and the heat generating lamp which acts as an actuator of the air circulation to circulate the air in natural convection into and out of the interior of the air cleaner. Is provided.

Opening the door of the dust collection room and the door of the sterilization chamber exposes the dust collection room, the sterilization chamber and the exhaust chamber, making it easy to replace and clean the sterilization lamp or the heat generator.

According to the present invention, as the air of the air cleaner is heated by the exothermic lamp, the indoor air flows into the air inlet provided in the door of the dust collecting chamber of the air cleaner by the action of the air convection to the exhaust pipe due to the difference in the air weight.

The dust of fine particles suspended in the air is quietly attached by the conventional composite filter mechanism provided in the door of the dust collecting chamber, and the air passes through the filter mechanism and moves to the sterilization chamber through the lower side of the dust collecting chamber.

Since there is no forced air blowing in the dust collecting chamber, the dust collecting action by the filter mechanism becomes very high.

Since a plurality of sterilization lamps provided on the wall surface of the dust chamber are irradiated with intensive ultraviolet rays facing the filter mechanism, various bacteria such as erythrocytes, branch bacteria, Escherichia coli, staphylococci, tuberculosis bacteria, etc. are killed as the irradiation time continues. Therefore, the air moved to the sterilization chamber is almost clean sterilized air.

The air flowing into the sterilization chamber is moved at a slow speed through the zigzag passage partitioned by the vertical diaphragm, and the air is sterilized again by the ultraviolet rays emitted from the sterilization lamp provided on the wall of the sterilization chamber so that the clean air passes through the exhaust chamber to the exhaust pipe. It is discharged and supplied to the room.

The reason why the speed of air movement in the sterilization chamber is slow is because the heating effect of the heating lamp in the exhaust chamber is increased along the exhaust pipe due to the difference in specific gravity of the air, so the power of the heating lamp is only 100w. It will slow down. Slow air movement speed increases ultraviolet irradiation time and improves sterilization ability.

On the other hand, if the air flow is slow, the amount of sterilized air supplied to the room is not so high. However, since the air cleaner operates indoors day and night with little energy, it is insufficient for the sterilization of indoor air in hospital rooms or homes with limited space. Without is enough.

Since the air purifier of the present invention intensively sterilizes various bacteria adhered to the filter mechanism by irradiating ultraviolet rays to the filter mechanism, the sterilizing effect is very high compared to simply passing air through the ultraviolet region.

In addition, since there is no operation noise of the air purifier, it can be useful to clean the air at night in a quiet hospital room or home bedroom without disturbing a good night's sleep.

Opening the door of the dust chamber and sterilization chamber exposes the dust chamber, sterilization chamber, and exhaust chamber, making it easy to replace sterilization lamps and heat transfer lamps, and to clean the dust collection chamber, sterilization chamber, and exhaust chamber. Can be. Therefore, it is possible to use an air purifier that is hygienic and clean, since the elements for germ growth are removed.

The present invention partitions the collecting chamber and the sterilization chamber back and forth by the diaphragm on the side of the exhaust chamber to be associated with each other in the main body of the air purifier, the door is provided in the dust collection chamber and the sterilization chamber, respectively, and the air inlet and the filter mechanism are provided in the door of the dust collection chamber. When the door is closed, a sterilization lamp is provided on the wall surface of the dust collecting chamber facing the front and sterilizes the bacteria with high adhesion density through the filter mechanism through the dust during air filtration. The path of the sterilization chamber having the aluminum light reflecting surface coated with the photocatalyst by the action is gently moved up and down zigzag, and the sterilization lamp provided on the wall is strongly sterilized again to supply cleanly sterilized air to the room.

In addition, when the door of the dust chamber and the sterilization chamber are opened, the dust chamber, the sterilization chamber and the exhaust chamber are exposed, so it is easy to replace the sterilization lamp and the heat transfer lamp, and the dust chamber, sterilization chamber and the exhaust chamber can be easily cleaned and sanitarily clean. An air purifier can be used.

In addition, since there is no operation noise of the air purifier, it can be installed in the hospital room or the bedroom of the garden so that the air can be effectively cleaned without disturbing the sound sleep.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 and 5, in the air purifier, the collecting chamber 1 and the sterilization chamber 2 are partitioned on the side of the exhaust chamber 3 of the air at one side of the space B of the rectangular parallelepiped body B. It is partitioned back and forth by (4), and the through-hole 4h of air is provided in the lower part of one side of the diaphragm 4.

As shown in Figs. 2 and 3, the dust collecting chamber 1 and the sterilization chamber 2 are provided with doors 1d and 2d so as to be opened and closed by a hinge hg. Opening the door 1d of the dust collecting chamber 1 and the door 2d of the sterilizing chamber 2 exposes the interior of the dust collecting chamber 1, the sterilizing chamber 2, and the exhaust chamber 3.

As shown in Figs. 1 and 2, the door 1d of the sterilization chamber 1 is provided with an air inlet 1n and an ordinary compound filter mechanism f at the air inlet 1n. The composite filter mechanism f is selected from various filter mechanisms and the filter itself is known. On the wall surface 1w of the dust collecting chamber 1 facing when the door 1d is closed, a plurality of germicidal lamps UV are provided side by side at regular intervals to continuously irradiate the filter mechanism with ultraviolet rays.

Ultraviolet rays emitted from germicidal lamps (UV) are effective for sterilizing all bacteria, but their sterilization ability varies depending on the amount of ultraviolet rays, irradiation distance and irradiation time. Escherichia coli, which is an indicator of bacterial contamination, is killed when it is irradiated for 10 seconds at a distance of 10 cm by a 15-watt sterilization lamp, and various pathogenic viruses require 1.5 to 5 times that of E. coli, and about 3 to 6 times that of yeast. The sterilizing lamp (UV) of the dust collecting chamber may be provided with a plurality of 15-20 watt outputs (two sterilizing lamps are shown in the drawing).

Since the ultraviolet rays emitted from the germicidal lamp (UV) are continuously irradiated to the filter mechanism (f), the filter material and the dust of the filter mechanism are used as a medium during the filtration of air to concentrate sterilize various bacteria with high adhesion density in the filter. do.

As shown in FIG. 3, the passage d is zigzag in the middle of the sterilization chamber 2 through which air of the dust collecting chamber 1 flows through the through hole 4h provided at one side lower portion of the diaphragm 4. A vertical diaphragm 5 for dividing is provided with a vent hole 5h on the upper side to protrude from the wall vertically, and a plurality of germicidal lamps UV are disposed on the wall surface 2w of the sterilization chamber 2. It is provided on the left and right sides of 5) and sterilized by irradiating ultraviolet rays to the air moving in the upper and lower zigzag passages d of the sterilization chamber 2. In the embodiment of the present invention, the germicidal light (UV) has one output of about 15 watts.

The four-sided wall surface 1w of the collecting chamber 1, the four-sided wall surface 2w of the sterilization chamber 2, and the four-sided wall surface 5w of the diaphragm 5 are aluminum light reflecting surfaces AR coated with a photocatalyst. Ultraviolet rays emitted from (UV) are prevented from being absorbed on the wall, and all of them are reflected to help sterilization and increase sterilization ability.

As shown in Figs. 4 and 5, air flows into and out of the air cleaner internal space on the upper side of the exhaust chamber 3 partitioned by the diaphragm 6 with the sterilization chamber 2 and the exhaust hole 6h. A heating lamp (HR) (about 100w) is provided to act as an air circulation actuator to circulate in convection, and the exhaust pipe 3d is relatively vertically connected to the upper end of the exhaust chamber 3 (about 1 to 2m). have.

Increasing the output of the heat lamp (HR) is not preferable because the temperature is increased to increase the flow of air is lowered sterilization action. The moving speed of the air is a slow speed (about 10 cm / sec) such that dust adhering to the filter mechanism is not released again by the moving wind pressure of the air.

Closing the doors 1d and 2d of the dust collecting chamber 1 and the sterilizing chamber 2 blocks the dust collecting chamber 1, the sterilizing chamber 2 and the exhaust chamber 3 from the outside, and the air inlet 1n and the discharge pipe. Only by (3d), the indoor air can be collected and sterilized while circulating in and out of the air cleaner main body (B).

When the air purifier of the present invention having such a configuration is connected to a power switch (not shown), power is supplied to the heating lamp (HR) and the sterilizing lamp (UV), and the heating lamp (HR) as shown in FIGS. 4 and 5. As the air in the exhaust chamber 3 is heated, the air flows up into the exhaust pipe 3d due to the difference in the specific gravity of the air, so that the indoor air is the door 1d of the dust collecting chamber 1 of the main body B of the air cleaner. Flows into the air inlet (1n) provided in,

As shown in Figs. 2 and 5, the dust of the fine particles suspended in the air is quietly attached by the conventional composite filter mechanism f provided in the door 1d of the dust collecting chamber 1, and the air is the filter mechanism f. It passes through the through hole 4h of the lower side provided in the diaphragm 4 of the dust collecting chamber 1, and is moved to the sterilization chamber 2 side.

At this time, the plurality of germicidal lamps (UV) provided on the wall surface (1w) of the dust collecting chamber (1) facing the filter mechanism (f) in front of the ultraviolet rays continuously focused on the filter mechanism (f) at a short distance (10cm) As the irradiation time progresses, various bacteria including E. coli with high adhesion density are killed by the filter mechanism through the filter mechanism or the dust adsorbed on the filter mechanism.

Therefore, the air moved to the sterilization chamber 2 is clean air sterilized by bacteria contained in the air.

The air introduced into the sterilization chamber (2) is moved in a zigzag passage (d) partitioned by a vertical diaphragm (5) at a slow speed, and in the sterilization lamp (UV) provided in the wall surface (2w) of the sterilization chamber (2). The germ contained in the air is again sterilized by the emitted ultraviolet rays, and the clean air is introduced into the exhaust chamber 3 through the exhaust hole 6h partitioned by the diaphragm 6, and then discharged into the exhaust pipe 3d to be indoors. Sterilized clean air is supplied.

Sterilization lamp by aluminum light reflecting surface AR coated with photocatalyst provided on the wall surfaces 1w and 2w of the dust collecting chamber 1 and the sterilization chamber 2 and the wall surfaces 5w of the diaphragm 5, respectively. Ultraviolet rays emitted from (UV) are prevented from being absorbed by the wall, and all the emitted ultraviolet rays are reflected to help sterilization, which increases air sterilization ability.

In addition, by slowing the movement speed of air in the sterilization chamber, it is possible to increase the sterilization effect by increasing the ultraviolet irradiation time of the air.

In addition, since the sterilization effect is achieved by intensively irradiating ultraviolet rays by the sterilization lamp (UV) at the filter mechanism (f) side of the air purifier according to the practice of the present invention, the sterilization effect is compared with simply irradiating ultraviolet rays during the movement of air. It can be higher.

In addition, since there is no operation noise of the air purifier, it can be useful to clean the air in a quiet hospital room or home bedroom.

In addition, when the door 1d of the dust collecting chamber 1 and the door 2d of the sterilizing chamber 2 are opened, the dust collecting chamber 1, the sterilizing chamber 2, and the exhaust chamber 3 are exposed. It is easy to replace the overheating lamp (HR) and easy to clean every corner of the dust collecting chamber (1) and sterilization chamber (2).

Therefore, compared to the disassembly and disassembly of the side plate of the conventional air cleaner, the work procedure is reduced, and the elements for germ propagation are removed, so that the air cleaner can be used hygienically and cleanly.
