FIG. 1 is a sectional view showing the internal structure of an air purifier according to a preferred embodiment of the present invention, and FIG. 2 is a flowchart illustrating a process of operating an air purifier according to a preferred embodiment of the present invention.

As shown in FIGS. 1 and 2, the air purifying unit 20 and the lighting unit 10, which are a preferred embodiment of the present invention, are integrally formed and drawn into the interior of the wall, It can be used for interior lighting such as penthouses (warehouses), office buildings, etc. and for indoor air purification. In the present invention, an air purifier installed in a dressing room will be described as an example.

The air purifier includes an air purifying means 20 in which various devices used for purifying air are mounted in an internal accommodation space, and an air purifying means 20 which is integrally formed with the air purifying means 20 and which is separate from the internal accommodation space of the air purifying means 20 A lighting unit 10 equipped with various devices required to emit light in an internal accommodation space of a living room, a motion detection sensor 52 for sensing a movement of a person, and a pollution degree detection sensor 51.

The air purifying means 20 is a case which is drawn into the inside of the wall and is provided with an internal accommodation space. An inlet 25 through which the room air is sucked is formed at one side so as to communicate with the internal accommodation space of the air purifying means 20 An outlet 26 for discharging the purified air at a predetermined interval from the inlet 25 is formed. A filter 21 is mounted on the inlet 25 side and an air blower 22 and an air cleaner 23 are mounted on the outlet 26 side. A sterilizer 24 is mounted in the space between the filter 21 and the blower 22. The indoor air sucked through the inlet 25 passes through the filter 21 and passes through the space in which the sterilizer 24 is installed and is discharged to the outlet 26 through the blower 22. The air discharged to the outlet 26 is discharged while containing the air cleaner component discharged while the air cleaner 23 is operated.

A duct 31 is connected to the inlet 25 side of the air purifying means 20 so as to discharge the air before passing through the filter 21 to the outside. A ventilation fan (30) is installed inside the duct (31) and is used for discharging the room air outdoors. The ventilation fan 30 is preferably formed at a point where the duct 31 is connected to the air purifying means 20. [

The filter 21 is composed of a triple filter structure. It is preferable that the filter is formed of a laminated structure of three kinds of pre-filter, antibacterial filter and deodorization filter. The order of stacking, the number of stacks and the type of filter can be changed according to the demand of the designer or the user. The filter 21 may be composed of any one of a HEPA filter, a VOC promoting filter, an allergen filter, a low temperature plasma filter, and a photocatalytic filter.

The sterilizer 24 is installed in the interior space of the air purifying means 20 in contact with air passing through the filter 21 and can use UV LEDs. The sterilizer 24 is used to sterilize bacteria and fungi contained in the indoor air.

The lighting means 10 is formed on a surface exposed to the outside in a state of being drawn into the wall. The interior space of the lighting means 10 is separated from the interior space of the air-cleaning means 20. [ The illuminating means 10 comprises a light emitting member 11 which receives power and emits light to the room. The light emitting member 11 is composed of a plurality of LED lamps 11a.

The heat radiating fins (40) are brought into contact with the light emitting member (11) of the lighting means (10) to receive heat. The radiating fins (40) extend to the inner receiving space of the air purifying means (20). The radiating fins 40 transfer the heat generated in the light emitting member 11 to the internal accommodation space of the air purifying means 20 and are cooled while being in contact with the air flowing inside the air purifying means 20. [

The contamination detection sensor 510 is mounted in the internal space on the side of the inlet 25 of the air purifying means 20.

The movement detecting sensor 52 and the remote control signal receiving sensor 53 for receiving the remote control signal are mounted in the interior accommodating space of the illuminating means 10. [ Preferably on the side of the light-emitting member 11.

The control unit 12 stops the operation of the light emitting member 11 and operates the air purifying unit 20 when the movement of the person is detected by the motion detection sensor 52 and thereafter the movement of the person is not detected. The PCB constituting the control unit 12 is mounted so as to be exposed inside the air purifying unit 20 and to perform heat exchange with the room air. Further, it is preferable that the control unit 12 is mounted so as to be in contact with the radiating fins 40 so as to perform heat transfer.

The operation of the air cleaner constructed as above is as follows.

As shown in FIG. 2, first, a door detection step L1 for sensing the opening of the door that communicates with the room is performed.

After the opening and closing of the door is detected, a motion detection step (L2) for detecting a movement of a person is performed in the motion detection sensor (52). At this time, if motion is sensed, a light emission step L3 for operating the illumination means 10 to emit light to the room is performed, and if the motion is not sensed, the maintenance step L4 proceeds. The maintaining step L4 maintains the on state when the lighting means 10 is on, and maintains the off state when the lighting means 10 is off.

If the person is exited while the light emission step L3 is in progress and the movement of the person is not detected by the motion detection sensor 52, the maintenance step L4 proceeds. At this time, the maintenance step L4 maintains the lighting means 10 on for about 20 seconds.

Next, the power supply to the lighting means 10 is cut off and the waiting step L5 for operating the sterilizer 24 installed in the air purifying means 20 proceeds.

After the waiting step L5, an air purification step for operating the air purifying means 20 is performed.

The air purification step consists of the following steps.

After the waiting step L5, an operation step D8 for operating the blower 22 for a predetermined time period is performed. The operating time of the blower 22 set in the operation step D8 is preferably set to 5 minutes. When the air purifier 20 is started using the remote controller, the operation time of the blower 22 set in the operation step D8 is set to 2 minutes. In this way, the setting of the blower operation time is different from that in the case where the user is out and going, so that the initial operation time of the blower 22 is set to 5 minutes after the movement of the person is detected .

When the blower is initially operated, an operation step (D9) for operating the contamination detection sensor (51) proceeds. When the pollution detection sensor 51 is activated, the pollution measurement step D10 for measuring the pollution degree of the indoor air sucked by using the pollution detection sensor 51 is performed.

Next, a pollution degree determination step (D11) for judging whether the pollution degree measured by the pollution detection sensor (51) is within the set pollution degree range is proceeded. At this time, the range of pollution degree to be set can be changed according to the demand of the user. The set contamination degree range is preferably set to 20 to 50%. It is also possible to set the pollution degree range to be set as the pollution value. In the case of contamination levels, the extent of contamination can be changed by the user. (Mg / m ³ ) of benzene, toluene, xylenes, and the like. (Ppm) of formaldehyde or the like.

When the pollution degree measured by the pollution detection sensor 51 is 20 to 50%, a flow rate determination step (D13) for determining the air flow rate of the blower 22 is performed. At this time, the air volume of the blower is set to three stages of the strength, middle strength, and weakness according to the degree of contamination measured. When the pollution degree becomes low during operation, the blower 22 is turned off to stop the air purification operation. If the pollution degree of the blower 22 is about 20 ~ 30%, it corresponds to about 30 ~ 40%, and if the pollution degree is about 40 ~ 50%, it is adjusted to the steel. At this time, the range of the wind speed and the pollution degree can be changed according to the demand of the manager or the user.

When the rotational speed of the blower 22 is determined, a continuous operation step (D14) for moving the blower 22 is performed. After the continuous operation step (D14), the process proceeds to the pollution degree measurement step (D10) again.

When the pollution degree measured in the pollution degree determination step D11 is higher than the set pollution degree range, the operation of the air blower 22 is stopped and the ventilation fan 30 is operated. It is effective to discharge the contaminated room air to the outside rather than to purify the room air when the indoor pollution degree is too high. Accordingly, when the indoor pollution degree is higher than 50%, the operation of the blower 22 is stopped and the ventilation fan 30 is operated to discharge the indoor air to the outside through the duct 31. The operation of the ventilation fan 30 is stopped when a certain period of time passes or when the degree of pollution in the room is lowered.

The air purifier of the present invention can also be operated manually or automatically using a remote control. When the power supply step (D1) for operating the remote controller to supply power to the air purifying means 920 is performed as shown in FIG. 2, the air purifying means 920 is operated in the automatic operation mode or in the manual operation mode An automatic driving determination step (D2) is performed. When the automatic operation mode is determined, the above-described operation step (D8) proceeds. At this time, in the operation step D8, the operation time of the blower 22 is set to 2 minutes.

When the manual operation mode is determined in the automatic operation decision step (D2), the remote controller operation step (D4) for operating according to the manual formed on the remote controller proceeds.

Next, an air amount selection step (D5) for determining the air amount of the blower 22 as being strong, medium or weak is performed. When the air volume is selected, a time selection step (D6) for determining the operation time of the air purifying means (20) is performed. In this case, it is preferable to select one of 30 minutes, 60 minutes, and 120 minutes. The selected operating time can be changed according to the user's request.

The automatic operation mode switching step D7 for changing the air purifying means 20 to the automatic operation mode is performed so that the operation step D8 can proceed when the time selected in the time selection step D6 elapses. That is, when the operation of the air purifying means 20 is completed in the manual operation mode, the operation of the motion detecting sensor 52 and the operation of the air purifying means 20 are automatically performed by the pollution detecting sensor 51 Mode.

As described above, the air purifier according to the present invention combines the built-in lighting and the air purifying function in the dressroom so that the air purifier can be efficiently operated.

The lighting uses an energy-efficient LED, and adopts a PIR sensor, which detects human motion, as a motion detection sensor 52, so that illumination and air purification are automatically performed when a person's motion is sensed. Normally, it is very effective to automatically operate the lighting and air purifier at this moment because the room is contaminated in a situation where the person returning from the outing enters the dressing room and stores clothes worn outside.

In addition, it is possible to use the manual operation mode by the remote controller, so that the control is convenient and it is possible to meet the demand of the user who wants to operate the air cleaner at an arbitrary moment.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
