Technical field

The present invention relates to the technical field of air treatment, in particular to an air conditioner.

Background technique

Air conditioners usually have a cooling mode and a heating mode. The circulation of the refrigerant in the circuit formed by the compressor-condenser-throttle valve-evaporator-compressor can provide indoor air with a suitable temperature. However, there are situations where in addition to air temperature requirements, there are also requirements for other aspects of air quality, such as improvement in cleanliness and increase in humidity. The improvement of cleanliness is usually achieved by structures such as germicidal lamps and filters. The increase in humidity often requires the addition of a humidifying function structure in the air conditioner.

Still taking the increase in humidity as an example, as shown in Fig. 01, there is currently an air conditioner indoor unit: the housing has a return air outlet 01 and a supply air outlet 02, a volute 03 is arranged in the housing, a fan 04 is arranged in the volute, and a fan 04 is arranged downstream The evaporator 05 is equipped with a wet film support 06 downstream of the evaporator. The wet film support is provided with a wet film. The wet film is placed in water and supplied to the wet film by means of siphoning. The air flows back under the action of the fan 04. The air outlet is drawn into the shell and humidified by the evaporator and the wet film in sequence, and then sent into the indoor space through the air outlet. However, after a period of use, the humidification membrane tends to have problems such as calcification. If it is not replaced, the humidification effect will be reduced. In addition, after the microorganisms in the air stay in the humidifying film, the humidified air causes pollution that affects the health of the body.

Correspondingly, a new technical solution is needed in this field to solve the above-mentioned problems.

Summary of the invention

With this arrangement, it is possible to obtain a water film by directly supplying water to the spray member, and when the air flows through the water film, it collides with the water film to take away the water, so as to achieve a solution that does not cause pollution and does not require replacement of parts. Humidification program. In addition, by arranging a pump in the spray line, a better humidification effect can be achieved. For example, the quality of the water film can be changed by adjusting the operating parameters of the pump.

It can be understood that the structure, number, and location of the spray components can be flexibly selected according to actual conditions. For example, one spray member is provided on both sides of the indoor unit of the air conditioner (the side perpendicular to the blowing direction), and each spray member has only a pair of spray heads and the like.

For the above-mentioned air conditioner, in a possible implementation manner, an open structure is provided on the humidification box, and at least a part of the open structure is provided with a water-retaining member, wherein the water-retaining member allows air to be free on the one hand. Flowing into/out of the humidifying box, the water blocking member on the other hand can block at least one part of water from splashing out of the humidifying box.

Through such a setting, under the premise of ensuring the free entry and exit of air, water droplets can be prevented from splashing out of the humidification box, which improves the user experience.

For the above air conditioner, in a possible implementation manner, the open structure includes a first open structure and a second open structure, air flows into the humidification box through the first open structure, and the water film is humidified. Then, it is delivered to the indoor space through the second open structure and the air supply port in sequence, wherein the first open structure and/or the second open structure are provided with the water blocking member.

With this arrangement, it is possible to better prevent water droplets from splashing out of the humidification box.

For the above-mentioned air conditioner, in a possible implementation manner, the water blocking member has a mesh structure.

For the above-mentioned air conditioner, in a possible implementation manner, the mesh density of the mesh structure is 20-100 mesh.

For the above-mentioned air conditioner, in a possible implementation manner, the mesh density of the mesh structure is 40 mesh.

For the above-mentioned air conditioner, in a possible implementation manner, the thickness of the mesh structure is ≤ 20 mm.

For the above-mentioned air conditioner, in a possible implementation manner, the mesh structure is a polyurethane water-retaining mesh.

For the above-mentioned air conditioner, in a possible implementation manner, a heat exchanger is provided in the housing, and the humidification box is located between the heat exchanger and the air supply port, so that the air passes close to the heat exchange The direction of the device flows through the water film in the humidification box to the air supply opening.

For the above-mentioned air conditioner, in a possible implementation manner, the spray member can be detachably mounted to one or more positions of the humidification box.

Through this arrangement, it is possible to produce more diverse water films, such as the thickness, area, and orientation of the water film, so as to seek more diversified humidification requirements.

It is understandable that those skilled in the art can determine the number of spray components provided on the humidification box, the positions where the spray components can be installed, and the specific installation method according to actual conditions. For example, an installation position is provided on the two sides of the humidification box, and the spray component can be installed in any installation position. Or convert one installation position to multiple installation positions along the air supply direction. When two spray components are arranged in the humidification box, the installation position can be flexibly selected according to the actual situation to set the spray components, thereby shifting the water film On this basis, we will seek a more scientific humidification effect or more in line with user requirements.

In short, the air conditioner of the present invention provides a water film equivalent to that provided by the wet film in the prior art by spraying a pair of nozzles of the spray member to produce a water film. Since the water film starts to be produced against the spray water and disappears as the spray ends, the water quality is relatively fresh and will not breed bacteria. The quality of the water film can be adjusted by adjusting the water flow speed of the nozzle, which is more flexible when humidifying the indoor air.

FIG. 3 is an enlarged schematic view of part A in FIG. 2C. FIG. 4 shows an exploded schematic diagram of the humidification module of an air conditioner according to an embodiment of the present invention. A structural schematic diagram of a humidifying cover of a humidifying module of an air conditioner according to an embodiment of the present invention is shown, and FIG. 6 is a schematic structural diagram of a humidifying box of a humidifying module of an air conditioner according to an embodiment of the present invention. Air conditioners usually include an outdoor unit of an air conditioner and an indoor unit of an air conditioner. The outdoor unit of an air conditioner is mainly equipped with a compressor, an outdoor fan, and an outdoor heat exchanger (usually called a condenser). The indoor unit of an air conditioner is mainly equipped with an indoor heat exchanger (usually called As an evaporator), the compressor-condenser-evaporator-compressor forms a refrigerant circulation loop. When the refrigerant circulates along the compressor→condenser→evaporator→compressor, the air conditioner is in the refrigeration cycle. When the refrigerant circulates along the compressor→evaporator→condenser→compressor, the air conditioner is in the heating cycle. The indoor unit of the air conditioner includes a casing 1 installed (such as suspended on a wall or ceiling) or placed in the indoor space. The casing 1 is provided with a fan, an evaporator, a drain pan 3, and an electric control box, etc., on the casing 1. With air supply port 11 and return air port 12, when the air conditioner performs cooling/heating, the air in the indoor space is drawn into the shell through the return air port under the action of the fan, and after heat exchange with the surface of the evaporator, it is sent The air outlet is sent into the indoor space. The housing is provided with a drain pan drain joint 13 for draining the water from the drain pan, a refrigerant pipe joint 14 for filling refrigerant, a water source joint 15 (to supply water to the spray member below), and a lifting lug 16. The indoor unit of the air conditioner is fixed in the indoor space by lifting ears.

In the present invention, a new functional module is also provided in the housing. Specifically, a humidification module 2 for increasing the humidity of the air entering the indoor space is also provided in the housing. The humidification module is located between the evaporator and the air supply port. When the humidification module is working, under the action of the fan, the air in the indoor space enters the shell through the return air port, exchanges heat with the surface of the evaporator, and is sent into the indoor space through the air supply port.

It is understandable that in the process of increasing the humidity of the air, the cooling and/or heating can be stopped or can be carried out at the same time. If the humidification module of the present invention is used to achieve the function of increasing the humidity, it can be completed in a relatively short time, so the conventional cooling and/or heating of the air conditioner is suspended during the humidification. In addition, since the fan at this time only serves the humidification function, the operating condition of the fan can be adjusted more flexibly according to the humidification demand, thereby ensuring the degree of realization of the humidification function.

It should be noted that those skilled in the art can flexibly set the number and positions of fans according to actual conditions. For example, two fans (17a, 17b) can be set, and one or two of the fans can be set according to different air supply requirements. Both stations are running. In the case of general humidification requirements, it is enough to make one of the fans run. In this way, on the premise that the humidification target can be achieved, the noise and power usage problems that may be caused by the simultaneous operation of two fans can be avoided. In the case of urgent humidification demand, two fans can be operated at the same time. Such a setting can meet the humidification demand in a short time.

The humidification module includes a humidification box 21. The two sides of the humidification box are equipped with a spray member 5 respectively. The spray member has a pair of nozzles 55. The speed is 5-10m/s), a water film is formed inside the cavity of the humidification box. When the air flows through the water film at the position of the heat exchanger, it collides with the water film and takes away part of the water in the water film, thereby increasing the humidity. , And then delivered to the indoor space through the air outlet to achieve the humidification function.

7A and 7B, FIG. 7A shows a schematic structural view of the spray member of the humidification module of the air conditioner according to an embodiment of the present invention, and FIG. 7B shows the structure of the humidification module of the air conditioner according to an embodiment of the present invention. A schematic cross-sectional view of the spray component. In a possible implementation, the spray member 5 includes a base body having a water inlet end and a water outlet end. The outlet end is provided with a pair of nozzles 55 facing each other in spray directions, and a flow is formed between the water inlet end and the pair of nozzles. Channel so that the water entering from the water inlet can reach the nozzle through the flow channel corresponding to each nozzle. Specifically, the base body includes a first tube body 51 as a main tube. The first tube body extends outwardly with two second tube bodies 52 having a smaller diameter than the first tube body. The nozzle is arranged on the second tube body away from the first tube body. One end. Specifically, the second tube body includes a first branch tube 521 that extends radially outward of the first tube body and is perpendicular to the first tube body. A second branch pipe 522 having a smaller diameter than the first branch pipe extends axially and facing the other nozzle, and the nozzle 55 is arranged at an end of the second branch pipe away from the first branch pipe. In addition, the second branch pipe extends outwardly with a ring platform 5221 at a position close to the nozzle, so that the nozzle is located exactly in the middle of the ring platform.

It can be seen that the flow channel corresponding to the two nozzles is composed of the first tube body→the first branch pipe→the second branch pipe. In order to ensure the quality of the water film, the two pipelines corresponding to the nozzles are of symmetrical structure. It is understandable that the structural flow channels of each tube can also be in other forms. For example, the inner part of the first tube is divided into two cavities, and each cavity corresponds to the flow channel of a nozzle, and the first branch pipe and the second branch pipe are one. The arc-shaped pipe and the second branch pipe have a reduced diameter structure along the water flow direction.

The first pipe body has a third pipe body 53 extending outwards at a position corresponding to the water inlet end, and a hole 531 is provided at the corresponding position of the humidification box. The external thread of the third pipe body is equipped with a connecting pipe (such as a silicone tube) that matches the external thread, so that the spray component can be connected to the external water source. In this way, the water source passes through the silicone tube to the second After a pipe body, it is sent to a pair of opposite nozzles through the (first and second) branch pipes. The water accelerates at the nozzles and collides to produce splashes, forming a water film with a certain radius in the humidifying box. The pipeline is equipped with a special pump and water inlet valve, so that the quality of the water film can be adjusted by adjusting the parameters of the pump and the opening of the water inlet valve. For example, a pump and a water inlet valve are separately configured for each spray component, or a pump can be shared, and other methods such as a water inlet valve can be configured separately. Preferably, the humidification module is placed on the right side of the whole machine as a whole, and the water source is arranged on the right side of the humidification module, which is convenient for maintenance.

The first pipe body has two mounting ends 54 extending outward along the direction opposite to the extending direction of the second branch pipe. The fastener connects the spray member to the humidification module. Preferably, the two mounting ends are located on both sides of the third pipe body along the axial direction of the first pipe body. It can be understood that the number, specific form, and location of the mounting ends can be flexibly selected according to actual conditions, for example, two mounting ends are provided on both sides of the third pipe body.

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

It can be understood that the holes (531, 541) are only an exemplary description of the installation position for installing the spray component, and those skilled in the art can use other installation positions to realize the fixation of the spray component on the humidification box. For example, when the structure of the spray component is the same, adopt other installation methods, or when the structure of the spray component changes, adjust the specific form of the installation position accordingly.

As an improvement, more installation positions can be reserved for the spray component, so as to adjust the humidification level by adding or reducing the spray component or changing the installation position of the spray component. Still taking the above-mentioned holes (531, 541) as the installation position as an example, two height installation positions may be arranged along the height direction of the humidification box, or three or more installation positions may be arranged along the air supply direction of the humidification box. For example, the holes (531, 541) are arranged at intervals along the blowing direction. However, in order to prevent the liquid in the humidification box from splashing through the installation position, the installation position should be equipped with a corresponding blocking structure, such as a slidable plate inside the installation position.

In the air conditioner of the present invention, the humidification box is installed in the housing as a whole to facilitate the addition and removal of the humidification module in the air conditioner. 8A-8C, FIG. 8A shows an assembly schematic diagram of the humidification module of an air conditioner according to an embodiment of the present invention, and FIG. 8B shows an assembly schematic diagram of the humidification module of an air conditioner according to an embodiment of the present invention. 8C shows a schematic sectional view of the assembling of the humidifying module of the air conditioner according to an embodiment of the present invention. In a possible implementation, the left and right sides of the humidification box are respectively provided with brackets 213. The bracket 213 includes a horizontal portion 2131 extending outward and a vertical portion 2132 extending from the horizontal portion. The vertical portion is provided with a connection Component, the humidifying box is fixed to the shell through the connecting component. The connecting assembly includes two connecting members, specifically including a connecting hole 214 located above and a hook 215 located below. In this way, when installing the humidification box to the housing, first extend the hook 215 into the groove 2151 on the housing corresponding to the hook. At this time, the weight of the humidification box is supported by the housing, so the installer can be freed Hands. Afterwards, the humidification box is fixed to the housing by means of screws, bolts and other fasteners that cooperate with the connecting holes 214 and the corresponding holes 2141 on the housing. With such a setting, the humidification box can be installed by a single operation, which improves the convenience of operation.

The humidifying box is located above the water receiving tray 3. The humidification box is provided with a plurality of drainage holes at the position close to the water receiving tray, that is, the area near the bottom, so that the water sprayed from the nozzle can be discharged from the humidification box after participating in the humidification process. For example, a first drainage hole 211 and a second drainage hole 212 are respectively provided at the bottom of the humidification box and the bottom of the side walls on both sides of the humidification box. Preferably, the diameter of the second drainage hole is less than or equal to the first drainage hole to avoid During the collision between the air and the water film, water splashed out of the humidification box from the second drain hole. Preferably, the water in the (first and second) drain holes is introduced to the drain pan before being discharged from the air conditioner. Of course, a drain pipe can also be connected to any of the holes to drain the water directly from the air conditioner.

The humidification box has a first open structure and a second open structure on the upstream side and the downstream side of the air flow, respectively. At least a part of the first open structure and/or the second open structure is equipped with a water-retaining member, and the water-retaining member allows air on the one hand. It flows into the humidification box and on the other hand, at least a part of the water can splash out of the humidification box. That is to say, within the scope of ensuring good air exchange, the main function of the water blocking member is to prevent the water droplets splashing from the nozzle or the water droplets on the water film after colliding with the air from splashing out of the humidification box.

For example, the water-retaining member should usually be a mesh structure, such as a porous non-metallic filter, the thickness of the water-retaining mesh is ≤20mm, preferably 10mm; the mesh density of the water-retaining mesh is 20-100 mesh, preferably 20- 40 mesh. As an example, the water-retaining member is a polyurethane water-retaining net with a mesh density of 40 mesh (hereinafter referred to as the water-retaining net). Obviously, on the premise that the functions can be satisfied, those skilled in the art can also use water-retaining members with other parameters such as mesh density, thickness, material, structure, etc.

In a possible embodiment, the first open structure includes a first opening 31 and a second opening 32 provided on the rear side and/or top of the humidification box, and the second open structure includes a first opening provided on the front side of the humidification box. Three openings 33, the first opening is provided with a first water-retaining net 41, the second opening 32 is provided with a humidification cover 22, a second water-retaining net 42 is provided under the humidification cover, and the third opening 33 is provided with a third Water retaining net 43. Preferably, the water retaining nets (41, 42, 43) are respectively provided at the first opening, the second opening and the third opening in a detachable manner. Exemplarily, the second water-retaining net 42 at the top is fastened to the humidification cover by a buckle, and the third water-retaining net 43 on the front side and the first water-retaining net 41 on the rear side are fixed in the following manner: The front and rear sides of the box are reserved with inward edges 2251. A vertical baffle 2252 is provided on the inner walls of the two sides of the humidification box. The inner baffle, the side wall and the two sides of the humidification box Two stop grooves 225 are formed along the edge of the part, and the water retaining nets (41, 43) can be directly inserted into the corresponding stop grooves. For example, the thickness of the stop groove is 8-10mm, and the mesh density is 40. Purpose Hard polyurethane water retaining net. Obviously, the baffle can be a whole piece or composed of several spaced sheets. In addition, a baffle can also be added on the inner side of the bottom of the humidification box. Obviously, this is only an exemplary description of the stop groove. As long as the stop groove can meet the function of fixing the water retaining net, the stop groove can be designed in any reasonable form.

The humidification cover and the top outer edge of the humidification box are preferably assembled in a sealed manner to prevent water in the humidification box from splashing through the gap between the two. 2C and 3, in a possible embodiment, the humidification cover includes a cover body and a flange extending downward from the outer edge of the cover body, and the flange is overlapped to the humidification box. Specifically, the lower end of the flange has a first thinned portion 2241 that is thinned from the outside to the inside, and the upper end of the inner wall of the humidification box has a second thinned portion 2242 that is thinned from the inside to the outside. The outer surface of the thinned portion abuts against the inner surface of the second thinned portion. Wherein, since the front side and the rear side of the humidification box are respectively provided with water-retaining nets (43, 41), the inner surfaces of the first thinned parts corresponding to the front and rear sides of the humidification box respectively abut against the water-retaining The outer surface of the net (43, 41). It is understandable that any feasible manner for the sealed connection between the humidification cover and the humidification box, such as a sealing strip, can also be used.

Based on the realization of the sealed connection, a snap connection is added to the humidification box on the left and right sides of the humidification cover 22 to facilitate the replacement of the second water retaining net 42 under the humidification cover. For example, the specific form of the buckle connection is: two downwardly extending vertical strips 2231 are respectively provided on the left and right sides, two triangular holes 2232 are located below the vertical strips, and the humidification box is provided with a triangular hole at the corresponding position. The corresponding triangular protrusion 2233. In order to increase the area of the air intake, the humidification cover has a structure that slopes downward from left to right. In order to ensure the area of the water film at the same time, the included angle between the humidification cover and the horizontal plane is preferably not more than 30°. In order to ensure the ventilation performance at the second opening, many connecting structures are designed on the humidification cover. At the same time, in order to ensure the humidification function, the humidification cover is set as a closed structure at a position corresponding to the water film to allow water droplets in the waterproof film to leak out. For example, the humidification cover includes a long strip-shaped first area 221 corresponding to the water film, and two second areas 222 are respectively provided on both sides of the first area. According to the installation position of the nozzle, the position of the water film is different. The second regions may be the same or different. For example, each second region is provided with a plurality of ventilation holes 2221, the diameter of the ventilation holes is about 3 mm, and the distance between the ventilation holes is about 5 mm. Obviously, the pore size and density of the vent holes can be flexibly set according to the actual situation, such as uniform or uneven, and the diameter of each vent hole can be the same or different. In addition, the communication structure can also be any structure other than the air-permeable holes, such as strip-shaped holes, star-shaped holes, and the like.

According to the specific form of the first open structure, the air conditioner may have different humidification mechanisms. specifically:

In the case that the first open structure only includes the first opening, the air conditioner humidifies the air in the indoor space by humidifying the front air. The process of humidifying the front air is: under the action of the fan, the indoor air is drawn into the housing Inside, the air inside the housing passes through the first water retaining net 41 of the humidification module, decelerates and enters the humidification box, and then passes through the water film and collides with the water film and takes away the water in the process of passing through the water film. Part of the liquid thus achieves an increase in air humidity, and then reaches the outside of the humidification box through the third water blocking net 43, and finally enters the indoor space through the air outlet. In this way, the air in the indoor space can be humidified;

In the case that the first open structure only includes the second opening, the air conditioner humidifies the air in the indoor space by humidifying the top air. The process of humidifying the top air is: under the action of the fan, the indoor air is drawn into the housing Inside, the air inside the housing passes through the humidification box of the humidification module-the second water blocking net 42, slows down and enters the humidification box, then passes through the water film and collides with the water film and takes away water in the process of passing through the water film. Part of the liquid in the membrane thus achieves an increase in air humidity, and then reaches the outside of the humidification box through the third water retaining net 43, and finally enters the indoor space through the air outlet. In this way, the air in the indoor space can be humidified.

In the case that the first open structure includes the first opening and the second opening, the air conditioner humidifies the air in the indoor space by humidifying the mixed air. The process of humidifying the mixed air is as follows:

Under the action of the fan, the indoor air is drawn into the housing, and the air inside the housing is divided into two paths, passing through the first water retaining net 41 and the humidifying cover-second water retaining net 42 of the humidification module to decelerate and Enter the humidification box, then pass through the water film and collide with the water film and take away part of the liquid in the water film during the process of passing through the water film, thereby achieving an increase in air humidity, and then reach the humidification box through the third water retaining net 43 From the outside, it finally enters the indoor space through the air outlet. In this way, the air in the indoor space can be humidified.
