The air conditioner generally includes an outdoor unit and an indoor unit, the outdoor unit is mainly provided with a compressor, an outdoor fan and an outdoor heat exchanger (generally called condenser), the indoor unit is mainly provided with an indoor heat exchanger (generally called evaporator), and the compressor, the condenser, the evaporator and the compressor form a refrigerant circulation loop. The air conditioner is in a refrigeration cycle when the refrigerant circulates along the compressor → the condenser → the evaporator → the compressor. When the refrigerant circulates along the compressor → the evaporator → the condenser → the compressor, the air conditioner is in a heating cycle. The air-conditioning indoor unit comprises a shell 1 which is installed (such as suspended on a wall or a ceiling) or placed in an indoor space, wherein a fan, an evaporator, a water receiving disc 3, an electric cabinet and the like are arranged in the shell 1, an air supply opening 11 and an air return opening 12 are arranged on the shell 1, and when the air-conditioning is used for refrigerating/heating, air in the indoor space is pumped into the shell through the air return opening under the action of the fan, exchanges heat with the surface of the evaporator and then is sent into the indoor space through the air supply opening.

In the present invention, a new functional module is further provided in the housing, and specifically, a humidification module 2 for performing humidity increasing treatment on air entering the indoor space is further provided in the housing. The humidifying module is positioned between the evaporator and the air supply outlet. When the humidification module works, under the action of the fan, air in the indoor space enters the shell through the air return opening, exchanges heat with the surface of the evaporator and then is sent into the indoor space through the air supply opening.

It will be appreciated that cooling and/or heating may be stopped or performed simultaneously during the humidification of the air. The function of increasing humidity as achieved by the humidifying module of the present invention is accomplished in a short time, thus suspending the conventional cooling and/or heating of the air conditioner during the humidifying. In addition, because the fan only serves the humidification function, the running condition of the fan can be adjusted more flexibly according to the humidification requirement, and the realization degree of the humidification function is ensured.

It should be noted that, a person skilled in the art can flexibly set the number and the positions of the fans according to actual situations, for example, two fans (17a, 17b) can be set, and one or both of the fans can be operated according to different air supply requirements. Under the condition of general humidification requirements, one of the fans can be operated, so that the problems of noise, power use and the like possibly caused by the simultaneous operation of the two fans are avoided on the premise that the humidification target can be realized. And under the condition that the humidification demand is urgent, two fans can be enabled to operate simultaneously, and the humidification demand can be met in a short time by the arrangement.

The humidifying module comprises a humidifying box 21, two side parts of the humidifying box are respectively provided with a spraying component 5, the spraying component is provided with a pair of nozzles 55, after the pair of nozzles spray water towards the directions facing each other (for example, the speed of the sprayed water flow is 5-10m/s), a water film is formed inside a cavity of the humidifying box, when the air flows through the water film at the position of the heat exchanger, the air collides with the water film and takes away part of water in the water film, so that the humidity is increased, and then the air is delivered to the indoor space through an air supply outlet, so that the humidifying function is realized.

As further referring to fig. 7A and 7B, fig. 7A illustrates a structural schematic view of a spray member of a humidification module of an air conditioner according to an embodiment of the present invention, and fig. 7B illustrates a sectional schematic view of the spray member of the humidification module of the air conditioner according to an embodiment of the present invention. In a possible embodiment, the spray member 5 comprises a base body having a water inlet end and a water outlet end, the water outlet end being provided with a pair of nozzles 55 with their spray directions facing each other, the water inlet end and the pair of nozzles each forming a flow path therebetween, so that water entering from the water inlet end can reach each nozzle through the flow path corresponding to the nozzle. Specifically, the base member includes the first body 51 as being responsible for, and first body extends outward has two pipe diameters to be less than the second body 52 of first body, and the nozzle sets up in the one end that first body was kept away from to the second body. Specifically, the second pipe body includes a first branch pipe 521 extending radially outward along the first pipe body and perpendicular to the first pipe body, the first branch pipe extends at one end far away from the first pipe body along the axial direction of the first pipe body and to another nozzle to form a second branch pipe 522 having a pipe diameter smaller than that of the first branch pipe, and the nozzle 55 is disposed at one end far away from the first branch pipe of the second branch pipe. In addition, the second branch pipe extends outwardly with a ring stand 5221 at a position close to the nozzle, so that the nozzle is located just in the middle of the ring stand.

It can be seen that the flow path corresponding to the two nozzles consists of the first tube → the first branch → the second branch. In order to ensure the quality of the water film, the two pipelines corresponding to the nozzles are of a symmetrical structure. It can be understood that the structural flow channel of each pipe can also be in other composition forms, such as a flow channel which divides the interior of the first pipe body into two cavities, each cavity corresponds to one nozzle, the first branch pipe and the second branch pipe are arc-shaped pipes, the second branch pipe is a reducing structure along the water flow direction, and the like.

The first body has the third body 53 in the position that outwards extends corresponding to the end of intaking, corresponding position at the humidification box sets up porose 531, the part that stretches out the hole outside the third body has the external screw thread that can with the tube coupling, through dispose the connecting tube way (like the silicone tube) that matches with the external screw thread on the third body, can be connected to the outside water source with the component that sprays, so, after the water source lets in first body through the silicone tube, send a pair of nozzle of relative setting through (first, second) branch pipe respectively, water collides the production splash after nozzle department accelerates, form the water film of certain radius in the humidification box. And a special pump and a water inlet valve are arranged on the pipeline, so that the quality of the water film can be adjusted by adjusting the parameters of the pump and the opening degree of the water inlet valve. If a pump and a water inlet valve are respectively arranged for each spraying component, the pump and the water inlet valve can be respectively arranged in other modes. Preferably, the humidifying module is integrally placed at the position close to the right side of the whole machine, and the water source is arranged on the right side of the humidifying module, so that the humidifying module is convenient to overhaul.

The first pipe body is extended outwardly in a direction opposite to the extending direction of the second branch pipe with two mounting ends 54, for example, the mounting ends are cylindrical structures having internal threads, holes 541 are provided at corresponding positions of the humidification case, and the shower member is connected to the humidification module by means of fasteners. Preferably, the two mounting ends are located on both sides of the third pipe body in the axial direction of the first pipe body. It can be understood that the number, specific form and arrangement position of the installation ends can be flexibly selected according to actual conditions, for example, two installation ends are respectively arranged on two sides of the third pipe body.

In this embodiment, the axes of the (first, second and third) tubular bodies are coplanar, and the axes of the (first and second) branch pipes are respectively collinear with the axes of the (first and second) mounting ends.

It is understood that the holes (531, 541) are only an exemplary illustration of mounting locations for mounting the spray member, and that other mounting locations may be used by those skilled in the art to secure the spray member to the humidification cartridge. If the structure of the spraying component is the same, other installation modes are adopted, or when the structure of the spraying component is changed, the specific form of the installation position is adjusted correspondingly, and the like.

As an improvement, more mounting positions may be reserved for the spray member to adjust the humidification level by addition, subtraction, or change of the mounting position of the spray member. Also taking the mounting positions as the holes (531, 541) described above as an example, two mounting positions may be arranged in the height direction of the humidifying box, or three or more mounting positions may be arranged in the air blowing direction of the humidifying box. For example, the holes (531, 541) are provided at intervals in the air blowing direction. However, in order to prevent the liquid in the humidification chamber from splashing through the installation site, a corresponding blocking structure, such as a slidable plate, should be provided on the inner side of the installation site.

In the air conditioner of the present invention, the humidifying box is installed in the housing as a whole to facilitate the addition and removal of the humidifying module in the air conditioner. Referring to fig. 8A to 8C, fig. 8A is a first schematic assembly view of a humidification module of an air conditioner according to an embodiment of the present invention, fig. 8B is a second schematic assembly view of the humidification module of the air conditioner according to an embodiment of the present invention, and fig. 8C is a cross-sectional schematic assembly view of the humidification module of the air conditioner according to an embodiment of the present invention. In one possible embodiment, the humidifying box is provided with brackets 213 at left and right sides thereof, respectively, the brackets 213 include a lateral portion 2131 extending outward and a vertical portion 2132 extending from the lateral portion, the vertical portion is provided with a coupling assembly, and the humidifying box is fixed to the housing through the coupling assembly. The connecting assembly includes two connecting members, specifically, a connecting hole 214 located at the upper side and a hook 215 located at the lower side.

The humidifying box is then fixed to the housing by means of the engagement of fasteners such as screws, bolts, etc. with the connection holes 214 and the corresponding holes 2141 on the housing. Through such setting, the installation of humidification box can be accomplished to one-man operation, has improved the simple operation nature.

The humidifying box is positioned above the water receiving tray 3. The humidifying box is provided with a plurality of drain holes at a position close to the water receiving tray, namely, a region close to the bottom, so that water sprayed from the nozzles is drained out of the humidifying box after the water participates in humidifying treatment. If the bottom of the humidifying box and the bottom of the side walls at the two sides of the humidifying box are respectively provided with the first drain hole 211 and the second drain hole 212, the diameter of the second drain hole is preferably smaller than or equal to that of the first drain hole, so that the phenomenon that water splashes out of the humidifying box from the second drain hole in the process of colliding air and water films is avoided as much as possible. Preferably, the water in the (first and second) drain holes is guided to the water pan and then drained out of the air conditioner, and of course, a drain pipe may be connected to any one of the holes to directly drain the water out of the air conditioner.

The humidifying box has a first open structure and a second open structure along an upstream side and a downstream side of an air flow, respectively, and at least a part of the first open structure and/or the second open structure is provided with a water blocking member which allows air to flow into the humidifying box therethrough on the one hand and enables at least a part of the water to splash out of the humidifying box on the other hand. That is, the water blocking member mainly functions to prevent water droplets splashed from the nozzle or water droplets on a water film after being collided with air from splashing outside the humidifying box within a range where good air exchange is ensured.

For example, the water retaining member is usually a net structure, such as a porous nonmetal filter screen, and the thickness of the water retaining net is 0-20mm, preferably 10 mm; the mesh density of the water retaining net is 20-100 meshes, and preferably 20-40 meshes. As an example, the water blocking member is a polyurethane water blocking net (hereinafter simply referred to as a water blocking net) having a mesh density of 40 mesh. It is obvious that a person skilled in the art may also use water deflector elements with other mesh density, thickness, material, structure, etc., provided that the function is satisfactory.

Preferably, water blocking nets (41, 42, 43) are detachably provided at the first opening, the second opening and the third opening, respectively. Illustratively, the top second water blocking net 42 is fixed on the humidifying cover by a snap, and the front third water blocking net 43 and the rear first water blocking net 41 are fixed in the following manner: the front side and the rear side of the humidifying box are reserved with inward edges 2251, the inner walls of the two side parts of the humidifying box are respectively provided with a vertical baffle 2252, the inner baffle, the side wall of the humidifying box and the edges of the two side parts form two stop grooves 225, and the water blocking nets (41, 43) are respectively and directly inserted into the corresponding stop grooves, for example, a rigid polyurethane water blocking net with the thickness of 8-10mm and the mesh density of 40 meshes is installed in the stop grooves. Obviously, the baffle plate can be a whole piece or composed of several spaced pieces, and in addition, the baffle plate can also be added on the inner side of the bottom of the humidifying box. It is clear that this is only an exemplary illustration of a retaining groove, which can be designed in any reasonable manner, as long as it fulfils the function of fixing the water retaining net.

The top peripheral edges of the humidifying cover and the humidifying box are preferably hermetically assembled so as not to allow water in the humidifying box to spill through a gap therebetween. As with reference to fig. 2C and 3, in one possible embodiment, the humidifying cover includes a cover main body and a flange extending downward from an outer edge of the cover main body, the flange overlapping the humidifying box. Specifically, the lower extreme of turn-ups has the first attenuate part 2241 of outside-in attenuate, and the inner wall upper end of humidification box has the second attenuate part 2242 of inside-out attenuate, and under the state that the overlap joint is good, the surface butt of first attenuate part connects to the internal surface of second attenuate part. Wherein, because the front side and the rear side of the humidifying box are respectively provided with the water blocking nets (43, 41), the inner surfaces of the first thinned parts corresponding to the front side and the rear side of the humidifying box are respectively abutted to the outer surfaces of the water blocking nets (43, 41). It will be appreciated that the sealed connection between the humidifying cover and the humidifying box may be made in any feasible manner, such as a sealing strip or the like.

On the basis of realizing the sealing connection, the left side and the right side of the humidifying cover 22 are additionally connected with the humidifying box in a buckling manner, so that the second water retaining net 42 below the humidifying cover is convenient to replace. The specific form of the snap connection is as follows: two vertical bar plates 2231 extending downwards are respectively arranged at the left side and the right side, two triangular holes 2232 are arranged at the positions below the vertical bar plates, and triangular protrusions 2233 corresponding to the triangular holes are arranged at the corresponding positions of the humidifying box. In order to increase the air inlet area, the humidifying cover is of a structure which is inclined downwards from left to right, and in order to ensure the area of a water film simultaneously, the included angle between the humidifying cover and the horizontal plane is preferably not more than 30 degrees. In order to ensure the ventilation performance at the second opening, a plurality of communicating structures are designed on the humidifying cover, and meanwhile, in order to ensure the humidifying function, the humidifying cover is arranged to be a closed structure at a position corresponding to the water film so as to prevent water drops in the water film from leaking. If the humidifying cover includes a first region 221 having a long shape corresponding to a water film, and two second regions 222 are disposed on both sides of the first region, respectively, and the position of the water film is different according to the installation position of the nozzle, so that the two second regions may be the same or different, illustratively, a plurality of air holes 2221 are disposed on each of the second regions, the diameter of each air hole is about 3mm, and the distance between the air holes is about 5 mm. Obviously, the aperture and the density of the air holes can be flexibly set according to actual conditions, such as uniformity or non-uniformity, the aperture of each air hole can be the same or different, and the like. In addition, the communicating structure can also be any other structure except the air holes, such as a strip-shaped hole, a star-shaped hole and the like.

The air conditioner may have different humidification mechanisms according to a specific form of the first open structure. Specifically, the method comprises the following steps:

in the case where the first open structure includes only the first opening, the air conditioner humidifies air of the indoor space by a front air humidifying process of: under the effect of fan, the indoor air is taken into the casing inside, and the inside air of casing passes the first water blocking net 41 of humidification module, slows down and gets into the humidification box, then through the water film and with the water film bump and take away partial liquid in the water film in-process that passes the water film thereby realized the increase of air humidity, later reaches the outside of humidification box through third water blocking net 43, finally gets into indoor space through the supply-air outlet. The circulation is carried out, so that the air in the indoor space can be humidified;

in the case where the first open structure includes only the second opening, the air conditioner humidifies the air of the indoor space by a top air humidifying process of: under the action of the fan, indoor air is pumped into the shell, the air in the shell passes through the humidifying box-the second water blocking net 42 of the humidifying module, is decelerated and enters the humidifying box, then passes through the water film, collides with the water film and passes through the water film, and takes away part of liquid in the water film so as to increase the air humidity, then reaches the outside of the humidifying box through the third water blocking net 43, and finally enters the indoor space through the air supply outlet. The air in the indoor space can be humidified by circulating the air humidifying device.

In the case where the first open structure includes the first opening and the second opening, the air conditioner humidifies air of the indoor space by a mixed air humidifying process of:
