One example in the related art is that a centrifugal fan is arranged above a water tank, a fan shaft of the centrifugal fan is vertically arranged and extends into the water tank to be in transmission connection with a water throwing piece, and the centrifugal fan drives the water throwing piece to rotate around a vertical axis so as to throw water in the water tank into a purification air channel.

Another example in the related art is that a fan shaft of a centrifugal fan extends horizontally, and the fan shaft is collinear with a rotational axis of a water slinger. Wherein, centrifugal fan's fan import just faces with getting rid of the water piece, and the air current that centrifugal fan drove can drive gets rid of the water piece and rotates to in making the water in the water tank be got rid of the purification wind channel, centrifugal fan's fan export orientation top.

However, with this arrangement, the centrifugal fan in one example requires modification of the fan shaft to enable the fan shaft to extend into the water tank to be in transmission connection with the water slinging member; in another example, the volute of the centrifugal fan needs to be modified to directly communicate the fan outlet of the centrifugal fan with the air outlet, or a wind guide shell is arranged in the casing and communicates the fan outlet with the air outlet. Therefore, in any of the above examples, the centrifugal fan needs to be modified, or the air guide casing needs to be added, which leads to high design cost.

Fig. 1 is a schematic structural diagram of an air treatment device in an embodiment of the present application, and fig. 2 is a schematic disassembly diagram of the air treatment device in the embodiment of the present application. Referring to fig. 1 and 2, an embodiment of the present application provides an air processing apparatus 10 for an air conditioner indoor unit, where the air conditioner indoor unit includes a casing, a heat exchange air duct is formed on the casing, and indoor air may enter the heat exchange air duct to perform heat exchange, so as to implement cooling or heating; the air treatment device 10 is used to purify indoor air.

The air treatment device 10 comprises a water tank 11, a water throwing piece 12 and a centrifugal fan 13, wherein the water throwing piece 12 is arranged in the water tank 11, and the centrifugal fan 13 is arranged outside the water tank 11.

Fig. 1 and 2 show a water tank 11 having a cubic shape, and the cubic water tank 11 has a cavity therein for containing water. Of course, in other embodiments, the water tank 11 may also have a regular shape such as a cylinder shape or other irregular shapes, which is not limited in this embodiment.

The water tank 11 is further provided with a purified air inlet 111 and a purified air outlet 112, and the purified air inlet 111, the cavity inside the water tank 11 and the purified air outlet 112 are sequentially communicated to form a purified air duct. It should be noted that the purification air duct and the heat exchange air duct are independent from each other, so that the heat exchange operation and the air purification operation of the air conditioner indoor unit are independent from each other and do not affect each other, so as to avoid affecting the heat exchange function of the air conditioner indoor unit, and the air treatment device 10 can be set as an independent module, which is convenient to detach and install.

The casing is provided with an air inlet and an air outlet, the purified air inlet 111 is communicated with the air inlet, the purified air outlet 112 is communicated with the air outlet, and the centrifugal fan 13 guides the indoor air to introduce the indoor air into the purification air channel through the air outlet for purification, and then sends the purified air out of the air outlet to the indoor space, so that the cleanliness of the indoor air can be improved.

Specifically, the centrifugal fan 13 is disposed above the water tank 11, and a fan inlet of the centrifugal fan 13 communicates with the purified air outlet 112, and a fan outlet of the centrifugal fan 13 communicates with the air outlet of the cabinet. Therefore, when the centrifugal fan 13 is operated, the indoor air purified in the purification air duct can be drawn into the centrifugal fan 13 from the fan inlet and sent into the room after flowing from the fan outlet to the air outlet.

Wherein, the fan shaft of the centrifugal fan 13 extends along the vertical direction, and the centrifugal fan 13 of this embodiment is configured to axially supply air and radially supply air. That is, the central axis of the fan inlet of the centrifugal fan 13 is perpendicular to the ground, and the central axis of the fan outlet of the centrifugal fan 13 is parallel to the ground. From this, centrifugal fan 13's fan export is towards the casing in this embodiment, so reasonable setting centrifugal fan 13's position can be so that fan export direct alignment air outlet, compares with centrifugal fan 13's fan export orientation top among the correlation technique, sets up like this, need not to make the change or add wind guide shell to centrifugal fan 13's spiral case, and then is favorable to reducing design cost.

The air treatment device 10 further comprises a driving mechanism, the driving mechanism is used for driving the water throwing piece 12 to rotate, the water throwing piece 12 is arranged in the purification air channel in a rotatable mode, one part of the water throwing piece 12 can extend to the position below the water surface, when the water throwing piece 12 rotates, the water can be moved, water is thrown into the purification air channel under the centrifugal effect, small liquid drops moving in a large amount are distributed in the purification air channel, and the water throwing surface is formed. From this, when the air was imported by purification wind channel flow direction fan, the air current can collide with the droplet through the water curtain, and impurity such as dust, hair or fine hair wadding in the air is dissolved in the aquatic and falls back to in the water tank 11, and then makes the impurity in the air filtered, and in addition, the humidity of air has also obtained the improvement. That is, the water slinger 12 treats the air with water to freshen the air flow from the air outlet.

It should be noted that the axis of rotation of the water slinger 12 extends horizontally, i.e. the water slinger 12 rotates about a horizontal axis to form a water slinger around the horizontal axis. So set up, compare with the water slinging face that is on a parallel with the horizontal plane that water slinging piece 12 rotated around vertical axis and forms, the part liquid droplet of the water slinging face that this embodiment formed can fall back to on the surface of water slinging piece 12, then this part liquid droplet can continue to be thrown away, has played the effect that the secondary was thrown away.

Taking the cubic water tank 11 as an example, the rotation axis of the water slinger 12 may extend along the length direction of the water tank 11, may extend along the width direction of the water tank 11, or may be inclined to the length direction of the water tank 11

In summary, in the air treatment device 10 of the embodiment of the present application, the water throwing element 12 is driven by the driving mechanism alone, and the fan shaft of the centrifugal fan 13 does not need to be changed to drive the water throwing element 12; meanwhile, the fan outlet of the centrifugal fan 13 is configured to face the casing, and the fan outlet can be directly communicated with the air outlet, so that the volute of the centrifugal fan 13 does not need to be changed or the air guide casing does not need to be additionally arranged to guide air, and the design cost is favorably prevented from being increased.

Several implementations of the water slinger 12 are described below, but these implementations are not limiting:

FIG. 3 is a partially exploded view of the water tank and the driving mechanism of the air treatment device according to the embodiment of the present application. In a possible implementation manner, as shown in fig. 3, the water throwing member 12 includes a rotating shaft 121 and an impeller, the rotating shaft 121 extends in a horizontal direction, the rotating shaft 121 is rotatably installed on the water tank 11, and the impeller is sleeved on the rotating shaft 121. When the air conditioner indoor unit operates, the rotating shaft 121 drives the impeller to rotate, and the blades of the impeller raise the water in the water tank 11, so that a large amount of liquid drops splash in the purification air duct.

Specifically, a first mounting hole and a second mounting hole are formed in the side wall of the water tank 11, the first mounting hole and the second mounting hole are both provided with a rotatable shaft sleeve 123, and two ends of the rotating shaft 121 are respectively mounted in the shaft sleeve 123 of the first mounting hole and the shaft sleeve 123 of the second mounting hole.

In another possible implementation manner, the impeller may be replaced by a rotating disk, the rotating disk is sleeved on the rotating shaft 121, and a plurality of protrusions are uniformly arranged on the annular side wall of the rotating disk around the axis of the rotating disk. When the air conditioner indoor unit operates, the rotating shaft 121 drives the rotating disc to rotate, and the bulge on the rotating disc drives the water in the water tank 11 to be raised, so that a large amount of liquid drops splash into the purification air duct.

In the above two possible implementations, the impeller or the rotating disk may be provided in plurality, and the plurality of impellers/the plurality of rotating disks are arranged at intervals along the axial direction of the rotating shaft 121. Through setting up a plurality of impellers/carousel, then can be formed with a plurality of surfaces of getting rid of in purifying the wind channel, and then improved the air current through the possibility of the surface of getting rid of to can make more air purified, purification efficiency is high.

In the above embodiment, the driving mechanism 14 is used to drive the rotating shaft 121 to rotate to drive the impeller to rotate. Specifically, the driving mechanism 14 may include a driving motor 141 and a transmission device, and the driving motor 141 is in transmission connection with the rotating shaft 121 through the transmission device to transmit power to the rotating shaft 121.

For example, the transmission device may be a gear transmission device, and accordingly, the transmission device specifically includes a driving gear 142 and a driven gear 143, the driving gear 142 is sleeved on a motor shaft of the driving motor 141, the driven gear 143 is sleeved on the rotating shaft 121, and the driving gear 142 is engaged with the driven gear 143.

For another example, the transmission device may also be a belt transmission device, and accordingly, the transmission device specifically includes a driving pulley, a driven pulley, and a belt, the driving pulley is sleeved on the motor shaft of the driving motor 141 and is sleeved on the rotating shaft 121, and the belt is wound on the driving pulley and the driven pulley. Of course, the transmission may also be a sprocket transmission.

It is worth mentioning that in the possible implementation manners described above, the gear transmission is more compact, which is advantageous for miniaturizing the air treatment device 10, and thus for avoiding the space occupied by the air treatment device 10 inside the air conditioner internal unit from being too large.

The water tank 11 of the embodiment of the present application is described below with reference to the drawings.

Fig. 4 is an exploded view of an air treatment device according to an embodiment of the present disclosure. Referring to fig. 4, the air treatment device 10 further includes a water tank base 15, a pick-and-place opening is provided on a side wall of the water tank base 15, and the water tank 11 is placed on the water tank base 15 and can be taken out from the pick-and-place opening in a horizontal direction. Set up like this, when needs are added water or are traded water for water tank 11, the user can remove water tank 11 along the horizontal direction and make it take out from water tank seat 15 through getting and putting the mouth, adds the water back that finishes, and the user places water tank 11 on water tank seat 15 again. In other words, the water tank 11 can be pulled to facilitate adding or replacing water.

Here, it should be further noted that the housing is further provided with a mounting opening, which is opposite to the access opening and is configured to allow the water tank 11 to pass through, so that a user can pull the water tank 11 through the mounting opening, so that the water tank 11 can be taken out of the housing.

Wherein, the shape of the water tank seat 15 is similar to that of the water tank 11, so that the water tank seat 15 can be adapted to the water tank 11, and the water tank 11 can be more stably placed on the water tank seat 15. For example, in fig. 4, the tank holder 15 and the tank 11 are each cube-shaped.

Preferably, a drawing part for grabbing is further arranged on one side of the water tank 11 facing the access opening. Thus, the user can grip the drawing portion to apply force to the water tank 11, thereby facilitating drawing of the water tank 11. Specifically, the drawer may be a pull handle, a pull cord, or the like. In the example shown in fig. 4, a bottom of a side wall of the water tank 11 facing the access opening is provided with a groove 113, and a user can insert a hand into the groove 113 to hold the water tank 11.

In one example, the centrifugal fan 13 may be fastened to the water tank base 15, i.e. the centrifugal fan 13 is fixed to the water tank base 15, and the water tank 11 is movable relative to the water tank base 15 and the centrifugal fan 13. Thus, the centrifugal fan 13 fixed to the water tank base 15 does not move when the user pulls the water tank 11 to add water. It will be appreciated that in this embodiment, the top of the tank base 15 may be provided with a mounting plate for mounting with the centrifugal fan 13.

In another example, as shown in fig. 4, the top of the water tank 11 and the top of the water tank base 15 are both provided with openings, the air treatment device 10 further includes a top cover 16, the top cover 16 is tightly connected with the top of the water tank base 15, the centrifugal fan 13 is tightly connected with the top cover 16, and the top cover 16 covers the openings of the water tank 11. Therefore, the opening at the top of the water tank 11 can be used as a water filling port, and after the water tank 11 is taken out, a user can directly fill water from the opening at the top of the water tank 11, so that the water filling is convenient. Moreover, because centrifugal fan 13 is fixed on top cover 16 and water tank seat 15 fastening connection, consequently, the in-process of pull water tank 11, top cover 16 can not remove along with water tank 11, and then makes the top at water tank 11 of installing that centrifugal fan 13 can be stable.

In this example, the top cover 16 may also be considered as a cover for the water tank 11, and the water tank 11 and the top cover 16 together define a clean air duct. Wherein the purified air outlet 112 is disposed on the top cover 16, the centrifugal fan 13 is fixed on the top cover 16, and the fan inlet 131 is opposite to the purified air outlet 112, so that the purified air outlet 112 is communicated with the fan outlet.

Alternatively, the purge air inlet 111 may be provided on a side wall of the water tank 11. For example, the purge air inlet 111 is provided at the top of a side wall of the water tank 11 facing the pick-and-place port, which is not shielded by the water tank holder 15, and the purge air inlet 111 can directly communicate with the air outlet without providing a through hole for communicating the purge air inlet 111 with the air outlet on the water tank holder 15. It should be noted that, since the clean air inlet 111 and the pick-and-place port are on the same side of the tank base 15, the air inlet and the mounting port are on the same side of the cabinet in order to ensure that the clean air inlet 111 communicates with the air inlet and the pick-and-place port communicates with the mounting port. Further, the mounting port and the air inlet may be shared.

Alternatively, the purge air inlet 111 may be provided on the top cover 16. With this arrangement, compared with the purified air inlet 111 provided on the side wall of the water tank 11, on the one hand, the water in the water tank 11 does not flow out from the purified air inlet 111, and the water storage amount of the water tank 11 is larger; on the other hand, it is advantageous to reduce the possibility that the liquid droplets thrown out by the rotation of the water slinger 12 are thrown out of the water tank 11 from the purified air inlet 111.

Further, the water slinger 12 is disposed directly below the purified air outlet 112. With this arrangement, the water throwing surface formed by the rotation of the water throwing member 12 is located right below the purified air outlet 112, and the air flowing into the water tank 11 from the purified air inlet 111 is more likely to contact with the water throwing surface in the process of flowing to the purified air outlet 112, thereby being beneficial to ensuring that the indoor air can be purified and improving the purification efficiency.

Further, the transmission is configured such that the rotation speed of the rotating shaft 121 is smaller than the rotation speed of the driving motor 141, i.e., the transmission is a reduction gear. Specifically, when the transmission is a gear transmission, the diameter of the driving gear 142 is smaller than that of the driven gear 143. Thus, when the rotation speed of the rotating shaft 121 is low, the rotation speed of the impeller or the turntable 122 is low, and the centrifugal force formed by the impeller or the turntable 122 is low, which is further beneficial to preventing the water brought up by the water slinging member 12 from being slinged into the centrifugal fan 13 from the purified air outlet 112 under the action of excessive centrifugal force.

It should be noted that the driving motor 141 is installed on the water tank 11, and the driving motor 141 does not protrude from the sidewall of the water tank 11. This is advantageous in preventing the water tank 11 from being taken out smoothly due to interference between the driving motor 141 and the water tank holder 15. Wherein, the driving motor 141 can be installed inside the water tank 11, or, as shown in fig. 4, the driving motor 141 is installed on the top of the sidewall of the water tank 11, and the driving motor 141 is flush with the outer surface of the sidewall of the water tank 11, so that the driving motor 141 does not contact the water tank base 15 during the drawing process.

Also, there is a gap between the driving motor 141 and the top cover 16 so that the driving motor 141 does not contact the top cover 16. Therefore, the water tank 11 can be prevented from being taken out smoothly due to the interference between the driving motor 141 and the top cover 16.

In addition, on the basis of the above embodiment, the air treatment device 10 further includes a protection net 17, and the protection net 17 is installed at the fan outlet of the centrifugal fan 13. From this, protection net 17 can play the guard action under the prerequisite that does not shelter from the fan export, is favorable to avoiding user's hand to stretch into centrifugal fan 13 in from the air export mistake and cause danger.

An air conditioner indoor unit according to an embodiment of the present application is described below with reference to the drawings.

Fig. 5 is a first schematic diagram of air flow of an air conditioner indoor unit in the embodiment of the present application. Referring to fig. 5, an air conditioner indoor unit 100 according to an embodiment of the present application includes a casing 20, a heat exchanger 30, a driving fan 40, and an air treatment device 10, where the casing 20 is provided with an air inlet and an air outlet, the heat exchanger 30 is disposed between the air inlet and the air outlet, and the driving fan 40 is disposed between the heat exchanger 30 and the air outlet. It should be understood that the air inlet, the interior of the housing 20 and the air outlet are in communication in sequence to collectively form a heat exchange air duct.

When the air conditioner indoor unit 100 operates, the driving fan 40 drives indoor air to enter the casing 20 from the air inlet to exchange heat with the heat exchanger 30, and then sends the air after heat exchange out of the air outlet to the outdoor, thereby realizing cooling or heating.

The housing 20 is further provided with an air inlet 212 and an air outlet 213, and the air treatment device 10 can guide the indoor air from the air outlet 213 into the clean air duct of the air treatment device 10 and send the cleaned air from the air outlet 213 into the room to achieve cleaning.

The air conditioner indoor unit 100 in the embodiment of the present application may be a floor air conditioner or a wall-mounted air conditioner, and the present embodiment is not limited thereto. Further, when the air conditioner indoor unit 100 is a vertical air conditioner, the air conditioner indoor unit 100 may have a cylindrical shape or a cubic shape. Taking the vertical air conditioner indoor unit 100 as an example, the air treatment device 10 may be disposed on the upper portion or the lower portion of the air conditioner indoor unit 100, so that the width or the length of the air conditioner indoor unit 100 is not increased, which is beneficial to avoiding the increase of the floor area of the air conditioner indoor unit 100. Here, the air treatment device 10 is disposed at the lower part of the air conditioner indoor unit 100, which may specifically mean that the air treatment device 10 is disposed below a water pan of the air conditioner indoor unit 100.

As can be seen from the above, the purification air duct and the heat exchange air duct are located in different spaces of the casing 20, i.e., the purification air duct and the heat exchange air duct are separated, so that the indoor unit 100 of the air conditioner can simultaneously perform indoor air purification and indoor air conditioning, and the two air ducts do not interfere with each other.

Fig. 6 is a schematic structural diagram of an air conditioner indoor unit in the embodiment of the present application. Referring to fig. 6, the casing 20 includes an air inlet panel 21 and an air outlet panel 22, the air outlet panel 22 faces the indoor, and the air inlet panel 21 faces away from the indoor. As can be seen from fig. 5 and 6, the air inlet 211 is disposed on the air inlet panel 21, and the air outlet is disposed on the air outlet panel 22, so as to form a heat exchange air duct with rear side air inlet and front side air outlet.

Similar to the air inlet 211, the air inlet 212 may also be disposed on the air inlet panel 21, which is beneficial to prevent the air after heat exchange from entering the purifying air duct from the air inlet 212 under the suction action of the centrifugal fan 13, compared with the case that the air inlet 212 is disposed on the air outlet panel 22.

Further, as shown in fig. 6, a maintenance opening is formed in the air intake panel 21, the air conditioner indoor unit 100 further includes a maintenance plate 23, the maintenance plate 23 is installed in the maintenance opening, the maintenance plate 23 is detachably connected to the air intake panel 21, and the air inlet 212 is formed in the maintenance plate 23. Thus, a maintenance person can open the maintenance opening by detaching the maintenance plate 23, thereby facilitating inspection of the condition of the air treatment device 10 or facilitating maintenance of the air treatment device 10.

Specifically, the maintenance plate 23 may have a grid-like structure or a net-like structure, and the maintenance plate 23 is formed with grid holes or net holes, which are used as the air inlets 212.

In some embodiments, the service port may also be used as a mounting port. In this example, the access port on the tank base 15 is aligned with the service port, and the service port allows the water tank 11 to pass through. When adding or replacing water, the user detaches the service panel 23 to open the service port and holds the drawing part to move the water tank 11, and the water tank 11 can be taken out of the cabinet 20 through the access port and the service port. Therefore, a mounting opening does not need to be formed in the casing 20, and the strength of the casing 20 is higher.

In the example shown in fig. 5, the air outlet 213 may be disposed on the air outlet panel 22, and in this case, the housing 20 may form an indoor air processing duct with rear side air inlet and front side air outlet, so that the purified air is directly blown into the room.
