In the description of the present invention, "a plurality" means two or more unless otherwise specified.
An air treatment device 40 for an air conditioning indoor unit according to an embodiment of the present invention will be described below with reference to fig. 1 to 10.
According to the air treatment device 40 for the indoor unit of the air conditioner, the indoor unit 1 of the air conditioner is provided with an indoor heat exchange air duct. Therefore, the indoor air can enter the indoor heat exchange air duct for heat exchange, thereby realizing the cooling or heating function of the air conditioner.
As shown in fig. 3, the air treatment device 40 includes a casing 430, a guiding fan 420 and a water treatment module 410, the guiding fan 420 and the water treatment module 410 are respectively disposed in the casing 430, the casing 430 is provided with an indoor air inlet 433 and an indoor air outlet 434, and an air treatment duct isolated from the indoor heat exchange duct is disposed in the casing 430. Thus, the indoor air can be introduced into the air treatment duct through the indoor air inlet 433 by the guide fan 420, and the treated indoor air can be discharged from the indoor air outlet 434.
As shown in fig. 1-3, the water treatment module 410 includes a water tank 411 and a water-fetching member 412, the water-fetching member 412 is rotatably disposed in the housing 430, and the water-fetching member 412 is configured as a passive rotating member driven by the air flow driven by the guiding fan 420, and the rotating water-fetching member 412 is used for guiding the water in the water tank 411 to the air treatment air duct so as to make water molecules contact with the air in the air treatment air duct.
It should be noted that the guiding fan 420 drives the air flow to flow, and when the flowing air flow passes through the water beating member 412, the water beating member 412 can be driven to rotate in the casing 430, and at this time, the water beating member 412 can throw the water in the water tank 411 into the air treatment air duct, so that a large amount of moving small droplets are distributed in the air treatment air duct to form a water curtain. The air passing through the water curtain collides with the small liquid droplets, so that the small liquid droplets moving in the air treatment duct can remove dust entrained in the air and can increase the humidity of the air. Therefore, when air flows in the air treatment duct, the air is washed by water, so that the air flow flowing out of the indoor air outlet 434 is fresher, and the indoor air quality is improved.
According to the above description, the air flow blown out through the indoor heat exchange air duct plays a role of conditioning indoor air, and the air flow blown out through the air treatment air duct plays a role of removing dust and humidifying indoor air. Because the indoor heat exchange air duct and the air treatment air duct are isolated from each other, the air treatment device 40 for the indoor unit of the air conditioner in the embodiment of the present invention does not affect the working efficiency of the indoor unit 1 of the air conditioner when performing air treatment.
According to the air treatment device 40 for the indoor unit of the air conditioner, provided by the guide fan 420 and the water treatment module 410, the guide fan 420 can introduce indoor air into the air treatment air duct, the water beating piece 412 can be driven to rotate by the airflow driven by the guide fan 420 to guide the water in the water tank 411 into the air treatment air duct, when the indoor air flows in the air treatment air duct, the dust particles in the air can be removed by the small liquid drops moving in a large amount in the air treatment air duct, and the humidity of the air is improved. Therefore, the indoor air is fresher, and the indoor air quality is improved. In addition, since the indoor heat exchange air duct and the air treatment air duct are isolated from each other, the air treatment device 40 for an air conditioner according to the embodiment of the present invention does not affect the working efficiency of the indoor unit 1 of the air conditioner when performing air treatment. In addition, the water beating piece 412 is set to be a driven piece which can be blown by wind, so that the rotation driving mechanism of the water beating piece 412 is simplified, and the blocking is avoided. The humidifying device has the functions of introducing indoor air and humidifying, and does not influence the heat exchange function of the air conditioner. Some air treatment devices 40 may be configured as a stand-alone module that is easily removable.
Specifically, the rotation axis of the water beating member 412 extends horizontally, and at least a portion of the water beating member 412 protrudes into the water tank 411. As shown in the example of fig. 2, a lower end portion of the water scooping member 412 protrudes into the water tank 411, and the water scooping member 412 is rotatable in a vertical plane. Therefore, when the water-beating piece 412 rotates, water in the water tank 411 can be thrown into the air treatment air duct so as to remove dust and humidify air in the air treatment air duct. Moreover, the part of the water beating part 412 is arranged to extend into the water tank 411, so that the resistance of the water beating part 412 during rotation can be reduced, and energy conservation and consumption reduction are realized.
In some embodiments, as shown in fig. 2-3, the water beating member 412 includes a water beating turntable 4121 and rotating blades 4122, the water beating turntable 4121 is configured to direct water in the water tank 411 to the air treatment duct, the rotating blades 4122 are connected to the water beating turntable 4121, the rotating blades 4122 are configured to be driven to rotate by the airflow driven by the guiding fan 420, and the rotating blades 4122 rotate to drive the water beating turntable 4121 to rotate. It can be understood that the rotating fan 4122 is driven by the airflow driven by the guiding fan 420 to rotate, that is, the water beating member 412 has neither a separate motor nor a coupling connected to the guiding fan 420, so that the design of driving the water beating member 412 to rotate by the airflow simplifies the structure of the water treatment module 410, reduces the production cost of the water treatment module 410, and thus the structure of the air treatment device 40 is simple and compact, and the production cost of the air treatment device 40 is reduced.
Specifically, as shown in fig. 2, the water beating turntable 4121 is provided with a plurality of through holes 41211, and each through hole 41211 penetrates through the water beating turntable 4121 in the axial direction of the water beating turntable 4121. It can be understood that by arranging the through hole 41211 on the water fetching turntable 4121, when the water fetching turntable 4121 rotates, the through hole 41211 on the water fetching turntable 4121 extending into the water tank 411 can be filled with water, and with the rotation of the water fetching turntable 4121, the water in the through hole 41211 can be thrown into the air treatment air duct, thereby improving the water vapor content in the air treatment air duct. Furthermore, when the water fetching turntable 4121 rotates at a slow speed, a water film may be formed at the through hole 41211, and when air passes through the water film, dust in the air may be removed and humidity of the air may be increased.
More specifically, the through-hole 41211 has a diameter of 1-8 mm. It can be understood that the diameter of the through hole 41211 is too small, and the water drops thrown out by the water beating turntable 4121 are smaller, so that the dust removal effect is reduced. The through-hole 41211 is too large, and a water film is not easily formed in the through-hole 41211, which also reduces the dust removing effect. Therefore, the adjustment of the through hole 41211 needs to be within a reasonable range.
In some embodiments, as shown in fig. 2, the plurality of rotating blades 4122 are circumferentially arranged, the water fetching turntable 4121 is sleeved on the plurality of rotating blades 4122, outer ends of the plurality of rotating blades 4122 are connected to the water fetching turntable 4121, and inner ends of the plurality of rotating blades 4122 are connected to the rotating shaft 4123. This arrangement may facilitate a reduction in overall size and arrangement of the water scooping member 412 and the guide fan 420.
In some embodiments, as shown in fig. 2, the water fetching turntable 4121 is plural, and the plural water fetching turntables 4121 are coaxially disposed. Therefore, the number of small droplets thrown out by the water-fetching turntable 4121 in the air treatment duct can be increased, and the collision probability between the small droplets and the air can be increased, so that the dust removal effect and the humidification effect of the air treatment device 40 can be further improved.
In some embodiments, as shown in fig. 3, the guiding fan 420 includes a centrifugal wind wheel, the centrifugal wind wheel is configured to axially wind in and radially wind out, the centrifugal wind wheel may also be configured to radially wind in and axially wind out, and the wind inlet end or the wind outlet end of the centrifugal wind wheel is disposed toward the water beating member 412.
Specifically, as shown in fig. 2 and 3, the plurality of rotating blades 4122 are disposed at the center of the water fetching turntable 4121, the wind wheel formed by the plurality of rotating blades 4122 is disposed coaxially with the centrifugal wind wheel, and the wind inlet end of the centrifugal wind wheel is disposed toward the wind wheel formed by the plurality of rotating blades 4122, so that the wind power can maximally drive the water fetching turntable 4121 to rotate.
In some embodiments, as shown in fig. 1-3, the housing 430 includes a pumping shell 431 and a driving shell 432, the pumping shell 431 is provided with an indoor wind inlet 433, a bottom of the pumping shell 431 forms a water tank 411, and the pumping member 412 is rotatably disposed in the pumping shell 431. The driving shell part 432 is connected with the water pumping shell part 431, an air passing opening 435 communicated with the water pumping shell part 431 is arranged on the driving shell part 432, an indoor air outlet 434 is arranged on the driving shell part 432, and the guide fan 420 is arranged in the driving shell part 432.
Of course, in the embodiment of the present invention, the indoor air inlet 433 may be disposed on the driving shell 432, and the indoor air outlet 434 may be disposed on the pumping shell 431, that is, when the wind direction is reversed, the positions of the indoor air inlet 433 and the indoor air outlet 434 are reversed. For simplicity, only the case where the indoor air inlet 433 is disposed on the water pumping shell portion 431 and the indoor air outlet 434 is disposed on the driving shell portion 432 is described as an example, and the case where the indoor air inlet 433 is disposed on the driving shell portion 432 and the indoor air outlet 434 is disposed on the water pumping shell portion 431 can be directly derived from this, and is not repeated herein.
Here, the wind wheel of the inducer fan 420 may be provided inside the driving case 432, and the motor of the inducer fan 420 may be provided outside the driving case 432. Alternatively, when the guiding fan 420 and the pumping unit 412 are coaxially disposed, the motor of the guiding fan 420 and the pumping unit 412 are disposed at two axial sides of the wind wheel of the guiding fan 420, and the motor shaft of the motor passes through the housing wall to be connected to the wind wheel, so as to achieve the purpose of protecting the motor.
It should be noted that the connection relationship between the water fetching shell portion 431 and the driving shell portion 432 can be various, for example, in some embodiments, the water fetching shell portion 431 and the driving shell portion 432 are formed as an integrally molded component. For another example, in some embodiments, the water fetching shell portion 431 and the driving shell portion 432 are formed as a detachable connection structure by using a bolt connection or a snap connection. For another example, in some embodiments, the water beating shell portion 431 and the driving shell portion 432 are fixedly connected by welding, riveting or the like.
Specifically, as shown in fig. 1 and 2, the pumping shell 431 includes a water bottom seat 4311 and a water cover 4312, the top of the water bottom seat 4311 is open and forms the water tank 411, and the water bottom seat 4311 is connected to the driving shell 432. The water sealing cap 4312 is open at the bottom, the water sealing cap 4312 is detachably covered on the water bottom seat 4311, and a shaft hole 4313 for matching with the rotating shaft 4123 of the water beating member 412 is formed between the water bottom seat 4311 and the water sealing cap 4312. Therefore, the phenomenon that water drops at the position where the water beating piece 412 is thrown away are scattered in a mess can be avoided, the structure limits the water drops thrown away by the water beating piece 412 to be filled in the cavity defined by the water beating shell part 431, and the purification effect of the air treatment device 40 is improved.
Specifically, as shown in fig. 1, the indoor air inlet 433 of the housing 430 is formed as a grill, which makes the air flow more uniform and prevents water from being excessively thrown out of the housing 430.
More specifically, as shown in fig. 4, a water blocking rib 436 is provided on an inner wall of the housing 430 adjacent to the indoor wind inlet 433, and a portion of the water blocking rib 436 extends toward the indoor wind inlet 434 and covers an inner side of the indoor wind inlet 434, thereby preventing the water splash from being splashed out of the housing 430 by the water splash 412. In fig. 4, the water blocking rib 436 is formed as an arc-shaped plate, and the water blocking rib 436 is plural, and the plural water blocking ribs 436 are respectively provided at the plural indoor air inlets 433 of the grill.
In some embodiments, the air treatment device 40 for an air conditioning indoor unit further includes a brake module (not shown) having a brake state in which the water striking member 412 is restrained and a brake release state in which the water striking member 412 is released. It will be appreciated that the brake module is used to control the state of motion of the paddling member 412. Specifically, when the brake module is in the braking state, the water striking member 412 cannot be rotated by the driving force of the air flow. At this time, the air treatment device 40 cannot perform a strong humidification and purification function on the air flow. When the brake module is in the released state, the striking member 412 may be rotated by the airflow. In this case, the air treatment device 40 can perform strong humidification and purification of air. Therefore, a user can select whether the air treatment device 40 carries out air humidification and purification according to needs, and the phenomenon that the air treatment device 40 is always in a working state to cause electric energy waste is avoided.
Here, the brake module may have various structural forms, for example, the brake module may be a solenoid valve, a spool of the solenoid valve may be electrically controlled to move, and when the spool stops against the water striking member 412, the rotation of the water striking member 412 may be prevented, and the solenoid valve may be in a braking state. When the valve core is reset to release the water beating piece 412, the water beating piece 412 can rotate, and the electromagnetic valve is in an unlocking state.
