the shell 10 is provided with an air treatment air duct which is mutually independent with the heat exchange air duct of the air conditioner, the air treatment channel comprises an air outlet section 14 and an air inlet section 13 which are communicated through a communication port 51 and distributed along the up-down direction, the air outlet section 14 is provided with an air outlet 12, and the air inlet section 13 is provided with an air inlet 11;

the water washing module is arranged in the air outlet section 14;

the filtering module 20 is arranged on the bottom wall 15 of the air inlet section 13 and is used for filtering the air passing through the air inlet 11; a kind of electronic device with high-pressure air-conditioning system

The water receiving convex part 30 is arranged on the bottom wall 15 and corresponds to the communication port 51, the outer diameter of the water receiving convex part 30 gradually decreases from bottom to top, the outer periphery of the bottom end of the water receiving convex part 30 is provided with a water receiving groove 31 with an upward opening, and the water receiving groove 31 is arranged opposite to the periphery of the communication port 51.

Specifically, in the present embodiment, the shape of the casing 10 may be numerous, and for better matching with the air conditioner, the shape of the casing 10 may be set according to the model of the air conditioner specifically used, and is not particularly limited herein, and a cylindrical shape is exemplified.

The positions of the air inlet 11 and the air outlet 12 may be many, and may be flexibly set according to different air duct types and different models, which is not particularly limited herein. For example, the air inlet 11 is formed at the back and/or the side of the housing 10; the air outlet 12 is formed at one or more of the front, side and top of the housing 10. Namely the positions of the air inlet 11 and the air outlet 12 can be set according to different machine types, different air channels and different user requirements. The shapes of the air inlet 11 and the air outlet 12 can be set according to the positions and actual requirements of the air inlet 11 and the air outlet 12, and the shapes of the air inlet 11 and the air outlet 12 can be various, for example, circular, elliptical, square, polygonal, etc., and are not limited in particular herein.

Specifically, the water washing module can be jointly composed of a water tank, a water pump and a water sprayer, wherein the water pump pumps water in the water tank into the water sprayer so that water forms a water curtain after passing through the water sprayer, and the water curtain cuts off an air treatment air channel, so that air passing through the air treatment air channel can be washed by the water, tiny particles in the air can be washed away, and air discharged from the air treatment module is cleaner and cleaner. Of course, the washing module may be formed by a washing net and a driving device for driving the washing net to move together, or the washing module may be formed by a water-beating wheel and a water tank together, and the washing module is not particularly limited herein.

Typically, the water after the air is washed by the water washing module is discharged to other positions without falling onto the bottom wall 15 of the air intake section 13. But because the fan 40 drives, can make some water fall in the air inlet section 13 when throwing around, simultaneously because the air is by the washing back, air humidity promotes greatly, when air humidity is too high, can form some drop of water, drop of water falls on the diapire 15 of air inlet section 13 from the intercommunication mouth 51 under the action of gravity. Therefore, in order to prevent the filtration module 20 from being wetted by the water falling onto the bottom wall 15, the bottom wall 15 is provided with the water receiving convex portion 30 corresponding to the communication port 51, the circumferential surface of the water receiving convex portion 30 is provided with the water receiving groove 31, when the water falls from the communication port 51, the water firstly drops onto the water receiving convex portion 30, then flows down along the water receiving convex portion 30, and finally is converged into the water receiving groove 31, thereby preventing the water on the bottom wall 15 from flowing to the filtration module 20.

In the present invention, the water receiving groove 31 is disposed opposite to the periphery of the communication port 51, which means that the projection of the communication port 51 on the water receiving convex portion 30 is located in the area surrounded by the outer groove wall of the water receiving groove 31, so that the water drops dropping along the periphery of the communication port 51 can be prevented from dropping on the periphery of the water receiving groove 31. The shape of the water receiving protrusion 30 may be various, for example, the water receiving protrusion 30 may be a cone, a truncated cone, a pyramid, or the like, and is not particularly limited herein. Since the air inlet section and the air outlet section are communicated through the communication port 51, the communication port 51 is not necessarily blocked by other members, that is, a gap is provided between the water receiving convex portion 30 and the periphery of the lower end of the communication port.

In the present embodiment, the water receiving groove 31 with an upward opening is formed at the outer periphery of the bottom end of the water receiving protrusion 30, and it is conceivable that an annular protrusion is provided on the outer peripheral surface of the water receiving protrusion 30, and the water receiving groove 31 is located on the annular protrusion; or the bottom surface of the water receiving convex part 30 forms a flanging, and the water receiving groove 31 is positioned on the flanging; alternatively, the bottom wall 15 is provided with a rib surrounding the water receiving protrusion 30, and the water receiving groove 31 is formed between the rib and the outer peripheral surface of the water receiving protrusion 30.

The filter module 20 may be disposed over the air inlet 11, i.e., against the side wall of the air inlet section 13. Of course, the filter module 20 may be spaced from the side wall of the air inlet section 13, so that in order to ensure that the air entering the air inlet section 13 through the air inlet 11 can be filtered by the filter module 20, the top end of the filter module 20 is in sealing contact with the top wall of the air inlet section 13, and the bottom end of the filter module 20 is in sealing contact with the bottom wall 15 of the air inlet section 13. The filter module 20 may be a HEPA filter, etc., and is capable of filtering out some particulate matter in the air.

Further, a fan 40 is provided in the air handling duct, preferably in the air outlet section 14, for driving air from the air inlet 11 into the air handling duct and out of the air outlet 12. The types of the fans 40 are numerous, and may be centrifugal fans 40, axial fans 40, cross-flow fans 40, and the like, and the types of the fans 40 are not particularly limited. Preferably, the fan 40 is a centrifugal fan 40, so that the air treatment duct is divided into an air inlet section 13 communicated with the air inlet 11 and an air outlet section 14 communicated with the air outlet 12, and a windward opening of the centrifugal fan 40 forms a communication opening 51. Of course, in other embodiments, a partition 50 may be disposed in the air treatment duct to partition the air treatment duct into an air inlet section 13 communicating with the air inlet 11 and an air outlet section 14 communicating with the air outlet 12, the communication port 51 is disposed on the partition 50, the fan 40 is mounted on the partition 50, and the air inlet side of the fan 40 corresponds to the communication port 51.

In the invention, the water receiving convex part 30 is arranged on the bottom wall 15 of the air inlet section 13, the water receiving groove 31 is formed on the water receiving convex part 30, and the water drops dropping from the communication port 51 fall on the water receiving convex part 30, so that the water flows to the water receiving groove 31 along the water receiving convex part 30 and is stored in the water receiving groove 31, thereby preventing the water from flowing to the filter module 20, and particularly when the filter module 20 adopts a HEPA (high efficiency particulate air) net, the filter module 20 can be prevented from being failed because the water receiving groove 31 is arranged to prevent the filter module 20 from contacting with the water. Meanwhile, the air treatment air duct is mutually independent of the indoor heat exchange air duct and the outdoor heat exchange air duct of the air conditioner, so that the heat exchange process of the air is not influenced in the air treatment process of the air treatment module, and the air conditioner can stably operate. In addition, the air treatment module is used for the air conditioner, so that more space can be saved for a user compared with the mode that the air treatment module is independently arranged, the structure of the air conditioner is more compact, and the space is fully and reasonably utilized while a new function is provided for the user.

In an embodiment of the present invention, the bottom periphery of the water receiving protrusion 30 is turned outwards and upwards to form an annular flange 32, and the annular flange 32 and the peripheral surface of the water receiving protrusion 30 together form the water receiving groove 31. The annular flange 32 is formed by directly folding the periphery of the water receiving convex part 30, so that the formed water receiving groove 31 has good sealing performance, and water leakage of the water receiving groove 31 can be avoided.

In order to enable all water falling from the communication port 51 to drop onto the water receiving convex portion 30 first, in an embodiment, the projection of the communication port 51 on the bottom wall 15 is located in the outer periphery of the bottom end of the water receiving convex portion 30, so that the water falling from the communication port 51 can be ensured to fall onto the water receiving convex portion 30. Since the water receiving convex part 30 is protruded on the bottom wall 15, the distance between the water receiving convex part 30 and the communication port 51 is relatively short, and then the water dropped from the communication port 51 is firstly dropped on the water receiving convex part 30, and the dropping distance is relatively short, so that excessive increase of gravitational potential energy of water drops is avoided, and the tendency that the water drops are dropped on the water receiving convex part 30 and splashed around is reduced.

In order to further prevent or reduce water from splashing around when falling onto the water receiving protrusion 30 from a high place, in an embodiment of the present invention, the outer peripheral surface of the water receiving protrusion 30 is covered with a buffer member, so that the kinetic energy of the water droplets is reduced after the water droplets are exposed on the buffer member, and the water droplets are prevented from splashing around to wet the filter module 20. Preferably, the buffer member may be made of sponge, silica gel or foam.

In order to prevent excessive water accumulation on the water receiving tank 31, the water washing module is communicated with the water receiving tank 31 through a water pumping pipe, and a water pump is arranged on the water pumping pipe, so that water in the water receiving tank 31 is pumped to the water washing module under the action of the water pump, and the water washing module is reused, thereby being beneficial to saving water. Of course, in other embodiments, a drain opening may be provided in the water receiving tank 31, and a drain pipe may be connected to the drain opening to drain the water in the water receiving tank 31.

In the above embodiment, the water receiving protruding portion 30 and the bottom wall 15 may be fixed by bonding, clamping or magnetic connection through a magnetic member, so that the water receiving protruding portion 30 is convenient to install and remove.

Further, a water blocking groove 16 is formed on the bottom wall 15, the water receiving protrusion 30 is located in the water blocking groove 16, and the filter module 20 is located outside the water blocking groove 16. Thus, when the water receiving tank 31 is full, the excessive water can flow to the water blocking tank 16, and the water blocking tank 16 further avoids the contact between the filtering module 20 and the water. Meanwhile, by providing the water blocking groove 16, part of the water drops splashed up by the contact with the water receiving convex part 30 can fall into the water blocking groove 16, thereby avoiding splashing on the filter module 20.

In this embodiment, the water-blocking groove 16 may be formed in various manners, for example, in one embodiment, a water-blocking rib 17 is disposed on the bottom wall 15 and surrounds the water-receiving protrusion 30, and the water-blocking rib 17 surrounds the water-blocking groove 16. Or in another embodiment, a partial area of the bottom wall 15 is recessed downward to form the water blocking groove 16. Still alternatively, the water blocking groove 16 may be formed by removing a part of the surface material from the bottom wall 15. In order to avoid that the water blocking ribs 17 block the air inlet of the filter module 20, the water blocking ribs 17 are arranged at intervals with the filter module 20. The specific distance between the water deflector 17 and the filter module 20 is not limited in the present invention, as long as the two are not in contact.

It should be noted that, the air treatment module is usually used with an indoor unit or an outdoor unit of an air conditioner, that is, the air treatment module is usually installed by a wall, and the yielding hole for the ventilation pipe on the wall to pass through is usually located at the back or the side of the air treatment module, and considering the arrangement of the ventilation pipe, the back of the casing 10 and/or the side of the casing 10 are provided with the air inlet 11, preferably, the back of the casing 10 and the side of the casing 10 are provided with the air inlet 11, so that when the air treatment module is installed, the air inlet 11 can be selected to be communicated with the ventilation pipe appropriately, thereby facilitating the communication between the air treatment module and the outdoor.

Further, considering that the gap between the air treatment module and the wall is relatively small after the air treatment module is fixedly installed, if the air outlet 12 is formed at the back of the air treatment module, the air outlet speed of the air treatment module is affected. In view of this, in one embodiment of the present invention, the air outlet 12 of the air treatment module is provided at one or more of the front, side and top of the housing 10. Preferably, the front, side and top of the casing 10 are provided with the air outlet 12, so that the area of the air outlet 12 of the air treatment module is increased, and the air treatment module can supply air in multiple directions, so that the air purified by the air treatment module can be quickly filled in all the indoor places, and the user experience is improved.

In addition, the air treatment module may be installed indoors or outdoors; specifically, when the air treatment module is installed indoors, the air inlet 11 of the air treatment module is communicated with the outdoors through an air duct; when the air treatment module is installed outdoors, the air outlet 12 of the air treatment module communicates with the room through a ventilation duct.

Further, when the air treatment module is installed indoors, the air treatment module may be installed at the top, bottom or inside of an indoor unit of the air conditioner; when the air treatment module is mounted below the indoor unit of the air conditioner, the air outlet 12 of the air treatment module is preferably disposed at the top, which makes the air outlet 12 of the air treatment module disposed more adjacent to the air inlet 11 of the indoor unit of the air conditioner. When the air treatment module and the indoor unit of the air conditioner work simultaneously, fresh air exhausted by the air treatment module can be directly sucked into the heat exchange channel of the indoor unit of the air conditioner and exhausted from the air outlet 12 of the indoor unit of the air conditioner after exchanging heat with the heat exchanger, so that the air exhausted from the air outlet 12 of the indoor unit of the air conditioner is more fresh, and further the user experience is improved.

When the air treatment module is installed outdoors, the air treatment module may be installed at the top, bottom or inside an indoor unit of the air conditioner.

It should be noted that, when the air treatment module is installed at the top or bottom of the indoor unit of the air conditioner or the outdoor unit of the air conditioner, the air treatment module is detachably connected with the indoor unit of the air conditioner or the outdoor unit of the air conditioner, so that the installation and the detachment of the air treatment module are facilitated; when the air treatment module is installed in the indoor unit of the air conditioner or the outdoor unit of the air conditioner, the air treatment module and the indoor unit of the air conditioner or the outdoor unit of the air conditioner are structurally integrated, so that the air treatment module is convenient to install.

The invention also provides an air conditioner which comprises an air conditioner indoor unit, an air conditioner outdoor unit and an air processing module, wherein the specific structure of the air processing module refers to the embodiment, and the air conditioner at least has all the beneficial effects brought by the technical scheme of the embodiment because the air conditioner adopts all the technical schemes of all the embodiments, and the detailed description is omitted. The air treatment module is arranged in the air conditioner indoor unit or the air conditioner indoor unit.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
