The air treatment device of the present application is described in detail below with reference to the accompanying drawings.

Referring to fig. 1, in which arrows in fig. 1 indicate a flow direction of air, an air treatment device according to an embodiment of the present application includes a cabinet 10 having an inlet 11 and an outlet 12, a blower 20 circulating air to the inside or outside of the cabinet 10, and a laser cleaning device 30 for cleaning air.

The cabinet 10 forms the general appearance of an air treatment apparatus, and has an inlet 11 and an outlet 12 formed therein, and air enters the cabinet 10 through the inlet 11, is treated, and is blown back into the room through the outlet 12. The housing 10 is further provided with an air duct 13 communicating the inlet 11 and the outlet 12, and air flows along the air duct 13 after entering the housing 11.

The fan 20 is disposed in the air duct 13. The fan 20 is used to blow air so that the air can flow from the inlet 11 to the outlet 12.

The air treatment device can be an air conditioner, a fresh air fan, a dehumidifier and the like. In either type of air treatment device, the air treatment device requires purified air.

The laser purification device 30 is disposed in the air duct 13 and is used for sterilizing the air flowing through the air duct 13. Specifically, the laser purification device 30 is disposed at the inlet 11 or within the air duct 13 for sterilizing and purifying the air from the inlet 11.

In other embodiments, referring to FIG. 21, an air treatment device includes an air handler 100 and an air duct 110. An air duct 110 communicates between the air handler 100 and the chamber for delivering air therebetween.

In this embodiment, the air treatment device 100 may be a central air conditioner with an air duct, an air duct machine, a total heat exchanger, etc., and most of these air treatment devices are installed in a suspended ceiling, and the air duct 110 is used to communicate the air treatment device 100 with the room.

The air handler 100 has an air duct 13 therein, and the laser purification apparatus 30 may be disposed in the air duct 13.

In other implementations, the laser purging device 30 may be disposed within the air duct 110 for sterilizing air flowing through the air duct 110.

Laser is a high-energy photon stream that causes absorption, excitation, oscillation, or ionization of biomolecules, resulting in the breaking or partial breaking of certain chemical bonds and even chromosome aberration. The mechanism of laser decontamination of microorganisms (such as bacteria, viruses, etc.) is as follows:

thermal effect: the laser is absorbed by bacteria or adhesive thereof to cause the temperature to rise rapidly and destroy the tissue structure of the bacteria;

chemical effects: the laser can cause the chemical bond of cell molecules to be broken;

mechanical effect: the laser impact deforms the cells in a compression way so as to break;

ionization effect: the laser generated plasma has certain killing effect on bacteria.

Laser can realize short-time sterilization, so that better air purification effect can be realized by using laser sterilization.

Referring to fig. 2 to 4, the laser purifying apparatus 30 includes a purifying housing 31, and a laser generator 32 for emitting laser light.

The purge housing 31 forms the general appearance of the laser purge device 30. With reference to fig. 1, air enters the housing 10 through the inlet 11, enters the laser purification device 30 through the inlet 311, is purified in the laser purification device 30, and then flows into the air duct 13 through the outlet 312.

Therefore, the air inlet 311 is closer to the inlet 11 than the air outlet 312 in the flow path of the air, that is, the air inlet 311 is located upstream of the air outlet 312.

A cleaning air duct 313 is formed between the air inlet 311 and the air outlet 312 in the cleaning housing 31. The air entering the air inlet 311 flows along the clean air duct 313 to the air outlet 312.

The laser generator 32 may be connected to the inside of the cleaning air duct 313 by means of screws, fasteners, or adhesives, and the laser generator 32 emits laser light to clean air.

Since the laser beam generated by the laser generator 32 is thin and has strong directivity, the area to which the laser beam is radiated is small, and only a small portion of air in the air duct can be purified. In order to improve the purification rate, in some embodiments of the present application, the inner wall of the purification housing 31 is designed to be a mirror surface, and the reflection of the laser beam inside the purification air duct 313 is increased by the mirror surface. Specifically, the inner wall of the purification casing 31 may be provided with a mirror surface layer, enhancing reflection by the mirror surface.

The air treatment device of the application, owing to set up laser purifier 30 in it, utilizes the characteristics that laser energy disinfects fast to reach better purifying effect and purification efficiency.

Moreover, in the laser cleaning device 30, since the inner wall of the cleaning housing 31 is configured as a mirror surface, the radiation range of the laser in the cleaning air duct 313 can be increased by using the principle of mirror reflection, and it is ensured that the flowing air can be cleaned by air.

According to some embodiments of the present application, the mirror layer may be formed by disposing aluminum foil, tin foil, or the like on the inner wall of the purification housing 31, which may be a smooth mirror material that can reflect light.

The mirror surface material may be attached to the inner wall of the purge case 31 by means of bonding. Or the processing technology is simple and the cost is low.

The laser purification apparatus 30 has an outer shape corresponding to the shape of the air duct 13. For example, the cross section of the air duct type air conditioning indoor unit is mostly rectangular, and then the purifying shell 31 of the laser purifying device 30 is rectangular; the cross section of the air duct of the fresh air blower is circular, so that the purifying shell 31 of the laser purifying device 30 is cylindrical; the inside of a large centralized heat exchange air conditioning equipment (such as AH U) has a large available space, so the shape of the laser purification device 30 is not limited, and can be spherical, rectangular or cylindrical.

Illustratively, referring to fig. 2, the laser purification apparatus 30 is a sphere, and the air inlet 311 and the air outlet 312 are disposed at two ends of the sphere having the same diameter. The laser generator 32 is positioned on one side of the spherical wall between the air inlet 311 and the air outlet 312; in addition, the number of the laser generators 32 may be one, or may be increased at an opposite position or a side position.

The laser light emitted from the laser generator 32 is continuously reflected within the sphere, so that the exposure time of the air flowing from the air inlet 311 to the air outlet 312 is prolonged.

Illustratively, referring to fig. 3, the laser purification apparatus 30 has a cylindrical shape, and an air inlet 311 and an air outlet 312 are respectively disposed on two circular surfaces of the cylindrical shape. The laser generators 32 are located on the side wall of the cylinder, and the number of the laser generators 32 may be one, or may be increased in opposite positions or in a side position.

The laser light generated by the laser generator 32 is continuously reflected on the sidewall of the cylinder, so that the exposure time of the air flowing through the air inlet 311 to the air outlet 312 is prolonged.

Illustratively, referring to fig. 4, the laser purification apparatus 30 is a rectangular parallelepiped, and a set of opposite faces of the rectangular parallelepiped are respectively provided with an air inlet 311 and an air outlet 312. The other four sides except the side where the air inlet 311 and the air outlet 312 are located are reflective surfaces, and the laser generator 32 may be disposed on the reflective surfaces, and in addition, one or more laser generators 32 may be disposed.

The laser generated by the laser generator 32 is reflected on the reflecting surface, so that the exposure time of the air flowing to the air outlet 312 through the air inlet 311 is prolonged.

In some embodiments of the present application, referring to fig. 5, the inner wall of the purification casing 31 is a concave curved surface, so that the laser can be reflected on the concave curved surface to make the reflected light more concentrated in the purification air duct, which is beneficial to improving the laser purification effect and purification efficiency.

When the purifying shell 31 is a cylinder or a sphere, the inner wall thereof is directly a concave curved surface, and the concave curved surface thereof can be directly utilized; when the purge case 31 has a rectangular parallelepiped shape, the inner wall thereof may be formed into a concave curved surface.

In some embodiments of the present application, referring to fig. 6 and 7, the inner wall of the purge housing 31 has a plurality of protrusions 314 thereon. Thus, when the laser beam is irradiated onto the convex portion 314, the diffuse reflection is easily formed, and the light irradiation area is increased.

The convex portions 314 may be distributed over the reflecting surface at predetermined intervals so that the laser beam is irradiated without dead angles inside the purge case 31.

The outer surface of the convex portion 314 is spherical, so that the reflection range of light rays can be increased.

The convex part 314 and the purifying shell 31 can be integrally formed and manufactured, and the manufacturing process is simple and the cost is low.

In some embodiments of the present application, referring to fig. 8-10, where arrows indicate air flow paths, the laser purging device 30 further comprises air guiding blades 33. The air guiding blade 33 is arranged in the purifying air channel 313 and extends from the side wall of the purifying air channel 313 to the center direction, so that the air guiding blade 33 blocks the air, the flow direction of the air in the purifying air channel 313 is changed, the flow path of the air is prolonged, the flowing time of the air in the purifying air channel 313 is prolonged, namely, the exposure time is increased, and the purifying rate of the air is improved.

According to some embodiments of the present application, the plurality of air guide blades 33 are arranged at intervals in the flow direction of the air. Thus, the flow direction of the air can be changed for a plurality of times, and the flow path of the air is prolonged.

In some embodiments, with particular reference to fig. 8, the purge air chute 313 has opposing first and second sidewalls; the air guide vane 33 includes a first air guide vane 331 and a second air guide vane 332, the first air guide vane 331 extends from the first side wall toward the center, and the second air guide vane 332 extends from the second side wall toward the center. The first air guiding vanes 331 and the second air guiding vanes 332 are arranged in a staggered manner from the air inlet 311 to the air outlet 312. In this way, the flow direction of the air is changed several times by the first air guide blade 31 and the second air guide blade 332 in sequence while the air flows, and the flow path is further extended, the exposure time is further increased, and the cleaning rate is further improved.

In addition, along the air flow direction, the first air guide blades 331 are arranged at intervals, the second air guide blades 332 are arranged at intervals, and the first air guide blades 331 and the second air guide blades 332 form a labyrinth path in the clean air duct 313, so that the air flow path is extended.

In some embodiments, referring to fig. 9 in particular, the air guiding blade 33 is disposed obliquely in the purge air duct 313, and the air guiding blade 33 is inclined toward the air outlet 312 from the sidewall of the purge air duct 313 toward the center. In this way, the inclined arrangement of the air guide blades 33 can reduce the wind resistance to the air while extending the air flow path.

In some embodiments, the air guide blade 33 may be provided swingably. The swing angle of the air guide blade 33 can be used to satisfy both the requirements of the purification rate and the wind resistance.

For example, when the air guiding blade 33 swings to 90 °, the air flow path is relatively long, the purification rate is high, but the wind resistance is large, and when it is necessary to mainly improve the air purification rate, the air guiding blade 33 can be controlled to swing to this angle (90 °); when the air guiding blade 33 swings to be approximately parallel to the air flow direction, the wind resistance is minimum, however, the flow path is not prolonged, the purification rate is relatively low, and when a large wind speed is required, the air guiding blade 33 can be controlled to swing to a small angle or even 0 degrees.

The air guide blades 33 are rotatably connected to the purification housing 31, and the plurality of air guide blades 33 are interlocked with each other by the link 34, so that the air guide blades 33 swing together with the link 34 when the link 34 moves.

The first driving member is connected to the link 34 for driving the link 34 to move. Specifically, referring to fig. 10, the first drive member may be in the form of a motor and rack and pinion arrangement. The connecting rod 34 is provided with a rack 341, the rack 341 is meshed with the gear 352, and when the gear 352 is driven by the motor 351 to rotate, the gear 352 drives the rack 341 to move, so that the connecting rod 34 moves.

In other embodiments, the first driving member may also be a pneumatic cylinder with a telescopic rod, an electric push cylinder or a hydraulic cylinder, etc. The telescopic rod is connected with the connecting rod 34, and the movement of the connecting rod 34 is realized through the extension and contraction of the telescopic rod.

According to the embodiment of the present application, the laser purification apparatus 30 further includes a fixing rod 36, the fixing rod 36 is fixedly connected to the inner wall of the purification air duct 313, a mounting hole is provided on the fixing rod 36, and the rotating shaft 333 on the air guiding blade 33 is fitted in the mounting hole. When the link 34 moves the air guide blade 33, the rotating shaft 333 rotates relative to the fixing rod 36.

The moving distance of the connecting rod 34 can control the swing angle of the wind guiding blade 33.

In some embodiments of the present application, since the different swing angles of the air guiding blades 33 affect the cleaning efficiency of the laser cleaning device 30, the air cleaning device may have a plurality of cleaning modes, such as a general cleaning mode, a strong cleaning mode, and the like, according to the different cleaning efficiencies.

The controller can control the air guide blades 33 to swing to corresponding angles according to different purification modes. For example, the air guide blade 33 swings to a preset angle α in the normal purge mode, and the air guide blade 33 swings to a preset angle β in the strong purge mode. The swing angle is an included angle between the air guide blade 33 and the extending direction of the purifying air duct 313, and alpha is smaller than beta. The air guide blade 33 has a better effect of prolonging the air flow path under a larger swing angle, and has higher purification efficiency.

In addition, different wind speeds can be correspondingly set in different purification modes. The controller controls the wind speed of the fan 30 according to different purification modes. For example, the fan corresponds to a wind speed a in the strong purification mode, a wind speed b in the general purification mode, and a wind speed c in the normal mode. B is more than or equal to a and less than c, the smaller the wind speed, the slower the flow speed of air in the purification air channel, the longer the exposure time, and the higher the purification rate; changing an idea, when a user selects a strong purification mode, the user is more concerned about the purification effect of the air, and at the moment, the wind speed is low, so that the purification requirement can be met preferentially; when the user selects the normal mode, the user is more interested in the basic performance, and the wind speed is higher at the moment, so that the requirement of the user on the basic performance can be met preferentially.

The working mode, the swing angle of the air guide blade 33 and the wind speed are stored in the memory in a one-to-one table form, and after receiving the working mode selected by the user, the controller controls the air guide blade 33 to swing to the corresponding angle according to the table and controls the fan 30 to operate at the corresponding wind speed.

The purification modes of different degrees enable the air treatment device to be more intelligent, and the purification requirements under different air pollution degrees are met.

In some embodiments, the swing angle of the air guide blade can also be controlled in linkage with the air volume, that is, the controller is used for adjusting the air guide blade to a corresponding angle according to the wind gear selected by the user.

Specifically, when the controller receives that a user selects a high wind gear, the air guide blade is adjusted to swing to a preset angle alpha 1; when the controller receives a low wind gear selected by a user, the swing of the air guide blade is adjusted to an angle beta 1, and alpha 1 is smaller than beta 1. The swing angle of the air guide blade is small when the wind gear is high, so that the air guide blade reduces the blockage of wind, and the requirement of a user on high wind volume is met preferentially; the swing angle of the air guide blade is large in the low wind gear, so that the air guide blade is additionally provided with a wind block, the flow path of air is prolonged, and the exposure time is prolonged. The user low profile indicates that the demand for basic performance is not high and purging may be prioritized.

In some embodiments, for convenience of description, both the intake opening 311 and the outtake opening 312 are referred to as an air opening.

Referring to fig. 11 to 13, the laser purification apparatus 30 may include a light barrier 37, and the light barrier 37 is disposed at the wind gap for blocking the laser and preventing the laser from leaking.

In an example, the position of the laser generator 32 in the purification air duct 313 may be determined first, and then the reflection path of the laser in the purification air duct 313 is calculated according to the reflection rule of the laser, so that the outward emission range of the laser at the air outlet can be known, and the light barrier 37 is disposed corresponding to the outward emission range, so as to block the laser and prevent the laser from leaking out.

In another example, the minimum air volume performance requirement of the product may be confirmed, the shielding area of the light barrier 37 to the purge air duct 313 is confirmed through the minimum air volume, and then the position range of the light barrier 37 is used as a point on the laser reflection path to reversely deduce the position of the laser generator 32 on the purge air duct 313. The mode can ensure the requirement of minimum air quantity while ensuring that the laser does not leak.

According to an embodiment of the application, the light barrier 37 is movable between a shielding position, in which the air opening is partially shielded, and an open position, in which the air opening is fully open.

When the laser generator 32 is in operation, the light barrier 37 is in the blocking position (fig. 11), blocking laser light from leaking; when the laser generator is not operating, the light barrier 37 is in the open position (fig. 12, 13), which avoids affecting the wind speed.

In some embodiments, the light barrier 37 is translatably movable between the blocking position and the open position.

When the light barrier 37 moves towards the direction close to the tuyere, the tuyere is shielded, and when the light barrier 37 moves towards the direction far away from the tuyere, the tuyere is opened.

The movement of the light barrier 37 is effected by a second drive. The structure of the second driving member is the same as that of the first driving member, and is not described herein again.

The light barrier 37 specifically includes an air inlet light barrier 371 disposed at the air inlet 311, and an air outlet light barrier 372 disposed at the air outlet 312.

For example, in fig. 11, the intake air blocking plate 371 blocks the lower portion of the intake opening 311 when moving upward, and blocks the upper portion of the outlet opening 312 when moving downward; in fig. 12, the intake vent 311 is opened when the intake shutter 371 moves downward, and the exhaust vent 312 is opened when the exhaust shutter 372 moves upward.

In some embodiments, referring specifically to FIG. 13, the light barrier 37 is rotatably movable between a blocking position and an open position.

When the light barrier 37 rotates to the air inlet, part of the air inlet can be shielded, and when the light barrier 37 rotates to the direction far away from the air inlet, the air inlet is completely opened.

Referring to fig. 14, the light barrier 37 can be rotated by a driving motor 38, a motor shaft of the driving motor 38 is connected to the light barrier 37, and the driving motor 38 rotates to rotate the light barrier 37.
