The second LED lamp 120 is rotatable relative to the photocatalyst filter 130, so as to increase the effective irradiation area of UVA on the photocatalyst filter 130, and further increase the air purification effect of the photocatalyst filter 130.
As a preferred embodiment, the air purification apparatus 100 further includes an LED lamp mounting base 140, referring to fig. 2 and 3, the first LED lamp 110 and the second LED lamp 120 are disposed on the LED mounting base 140, and the LED lamp mounting base 140 rotates relative to the photocatalyst filter 130 to adjust an angle between the second LED lamp 120 and the photocatalyst filter 130, so as to adjust an irradiation angle of the UVA on the photocatalyst filter 130, and increase an effective irradiation area of the UVA on the photocatalyst filter 130.
Further, with continued reference to fig. 2 and 3, the LED lamp mounting base 140 includes a fixing bracket portion 142 and a rotating bracket portion 141, the rotating bracket portion 141 is a long-strip-shaped structure extending along the width direction W of the air outlet 210 (or the air return opening), the fixing bracket portion 142 is rotatably disposed at the left end and the right end of the rotating bracket portion 141, the fixing bracket portion 142 is fixedly connected with the inner wall of the air duct, so as to integrally fix the air purification apparatus 100, and the first LED lamp 110 and the second LED lamp 120 are disposed on the rotating bracket.
The second LED lamp 120 rotates relative to the photocatalyst filter 130 by the rotation of the rotating bracket 141, fig. 2 shows a schematic structural diagram that the rotating bracket 141 rotates clockwise to a certain angle relative to the photocatalyst filter 130, and fig. 3 shows a schematic structural diagram that the rotating bracket 141 rotates counterclockwise to a certain angle relative to the photocatalyst filter 130.
Further, a driving motor 150 is disposed at the air outlet 210 (or the air return opening), a power output shaft of the driving motor 150 is connected to one end of the rotating bracket portion 141, and the driving motor 150 is used for driving the rotating bracket portion 141 to rotate.
Further, first LED lamp 110 and second LED lamp 120 equally divide and have a plurality ofly respectively, and a plurality of first LED lamps 110 and a plurality of second LED lamp 120 set up along the length direction interval of runing rest portion 141, improve illumination intensity, and then improve the air purification effect.
As a preferred embodiment, in order to ensure that each corner of the photocatalyst filter 130 can be irradiated by UVA, the operation process of the second LED lamp 120 rotating along with the rotating frame portion 141 includes that the second LED lamp 120 is perpendicular to the photocatalyst filter 130 (i.e., the rotating frame portion 141 is parallel to the photocatalyst filter 130), the second LED lamp 120 operates for t1 time in this state, then, the second LED lamp 120 rotates clockwise α degrees relative to the photocatalyst filter 130 (i.e., the rotating frame portion 141 rotates clockwise α degrees relative to the photocatalyst filter 130 in the state shown in fig. 2), the second LED lamp 120 operates for t2 time in this state, then, the second LED lamp 120 returns to the state perpendicular to the photocatalyst filter 130 (i.e., the rotating frame portion 141 is parallel to the photocatalyst filter 130) and operates for t1 time, then, the second LED lamp 120 rotates counterclockwise α degrees relative to the photocatalyst filter 130 (i.e., the rotating frame portion 141 rotates counterclockwise 7 degrees relative to the photocatalyst filter 130 in the state shown in fig. 3), and the second LED lamp 120 operates for t2 time in this state, and the second LED lamp operates for t 3536 time.
The reason why t2 is set to be equal to or greater than t1 is that, regardless of whether the second LED lamp 120 is operated in a state perpendicular to the photocatalyst screen 130 or the second LED lamp 120 is operated in an inclined state as shown in fig. 2 and 3, the photocatalyst screen 130 can always be irradiated with UVA at the middle position of the photocatalyst screen 130 (i.e., the portion facing the rotary holder portion 141) and the irradiation intensity at that position is the strongest, so t2 is set to be equal to or greater than t1, the operation time of the second LED lamp 120 in the inclined state is prolonged, each corner of the photocatalyst screen 130 can be effectively irradiated and excited, and the air purification effect of the photocatalyst screen 130 is improved.
As a preferred embodiment, the first LED lamp 110 and the second LED lamp 120 work alternately, and the proper LED lamp is turned on for purification according to the indoor air quality, so that the purification effect can be improved, and the energy consumption can be reduced.
Because the UVC emitted by the first LED lamp 110 does not act on the photocatalyst filter 130, and the first LED lamp 110 is not required to scan the photocatalyst filter 130 in a large area, when the first LED lamp 110 works, the rotating bracket portion 141 can stay at a position where the rotating bracket portion 141 is parallel to the photocatalyst filter 130, and at this time, the UVC can purify and sterilize the air flowing through the air outlet 210 (or the air return opening) to the maximum extent; when the second LED lamp 120 is operated, the rotating bracket 141 performs a rotating operation.
Through the alternate operation of the first LED lamp 110 and the second LED lamp 120, the service lives of the two LED lamps can be prolonged, and the service life of the driving motor 150 can be prolonged, and the energy consumption can be reduced.
Referring to fig. 4, the specific process of the first LED lamp 110 and the second LED lamp 120 alternately working includes that the rotating bracket portion 141 is parallel to the photocatalyst filter 130, at this time, the first LED lamp 110 and the second LED lamp 120 are both perpendicular to the photocatalyst filter 130, the first LED lamp 110 is turned off after being turned on for t3 time, then the rotating bracket portion 141 is not moved, that is, the second LED lamp 120 is kept perpendicular to the photocatalyst filter 130, and the second LED lamp 120 is turned on for t1 time, then the second LED lamp 120 is turned clockwise α degree relative to the photocatalyst filter 130 (that is, the rotating bracket portion 141 is turned clockwise α degree relative to the photocatalyst filter 130) and turned off after being turned on for t2 time, then the rotating bracket portion 141 is restored to the state parallel to the photocatalyst filter 130, that the first LED lamp 110 is turned off after being turned on for t3 time, then the rotating bracket portion 141 is not moved, the second LED lamp 120 is perpendicular to the photocatalyst filter 130, that the second LED lamp 120 is turned on for t1 time, and then the second LED lamp 120 is turned counterclockwise (that is turned off relative to the photocatalyst filter α degree) and turned counterclockwise relative to the photocatalyst filter 130 and turned off after being turned for t2 time.
At this point, the first LED lamp 110 and the second LED lamp 120 complete an alternating work process, and if the air needs to be purified continuously, the alternating work process of the first LED lamp 110 and the second LED lamp 120 is repeated; if the air does not need to be purified, the first LED lamp 110 and the second LED lamp 120 are both turned off, and the rotating frame 141 is returned to be parallel to the photocatalyst filter 130.
As a preferred embodiment, the indoor unit 200 of the air conditioner has an automatic cleaning mode, and referring to fig. 4, when the indoor unit 200 of the air conditioner is in the automatic cleaning mode, if the pollution index of the air is greater than or equal to the system set value, which indicates that there are more harmful gases in the air at this time, the first LED lamp 110 is turned off, and the second LED lamp 120 is turned on, so as to perform powerful cleaning on the air.
When the second LED lamp 120 works alone, in order to ensure that each corner of the photocatalyst filter 130 can be irradiated by UVA, and to improve the air purification effect, the angle between the second LED lamp 120 and the photocatalyst filter 130 needs to be adjusted, and the working process of the second LED lamp 120 rotating along with the rotating bracket portion 141 has been described in detail above, and is not described herein again.
As a preferred embodiment, the air conditioner indoor unit 200 further has a normal operation mode, and with reference to fig. 4, when the air conditioner indoor unit 200 is in the normal operation mode, the first LED lamp 110 and the second LED lamp 120 operate according to the above-mentioned alternating operation process, which is not described herein again.
It should be noted that, after the air conditioner 200 is turned on, if the user selects the automatic purification mode, the air conditioner 200 enters the automatic purification mode; if the user does not select the automatic cleaning mode, the air conditioner indoor unit 200 enters the normal operation mode.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
