In the related technical scheme, a water distribution part is provided on the outside of the evaporator of the indoor unit of the air conditioner, and the water distribution part applies humidifying water to the evaporator through the water distribution structure.

[0047] Example 1

[0048] See also Figure 1 and Figure 3 The main body of this embodiment is an air conditioner, which includes an air conditioner indoor unit 200 and a humidification structure 100 disposed in the air conditioner indoor unit 200. Figure 2 and Figure 4 , Figure 4 The humidification structure 100 provided in this embodiment is shown in FIG. It can be seen that, in this embodiment, the humidification structure 100 includes:

[0049] A cross-flow fan 180, wherein the cross-flow fan 180 includes an impeller 182 and a volute tongue 181 disposed radially outside the impeller 182;

[0050] an evaporator 110, the evaporator 110 being disposed outside the air inlet side of the crossflow fan 180, the evaporator 110 comprising a first end 110a and a second end 110b formed on the radially outer side of the impeller 182 and opposite to each other, the distance between the first end 110a and the volute tongue 181 being smaller than the distance between the second end 110b and the volute tongue 181;

[0051] A water distribution member 120 is provided with a plurality of water distribution structures 121 for applying humidifying water to the evaporator 110; the plurality of water distribution structures 121 are arranged in sequence along the evaporator 110 from the second end 110b to the first end 110a, and the flow area of ​​the water distribution structure 121 close to the first end 110a is larger than the flow area of ​​the water distribution structure 121 close to the second end 110b.

[0052] The crossflow fan 180 is mainly used to realize the delivery of airflow, and is mainly composed of an impeller 182 and a volute 181. The flow velocity at each location of the crossflow fan 180 is not uniform. For details, please refer to Figure 2During the rotation of the impeller 182, a vortex with its vortex center located at the volute tongue 181 is formed. The closer to the vortex center, the greater the flow rate of the airflow. Therefore, for the evaporator 110, since its first end 110a is closer to the volute tongue 181 than the second end 110b, the airflow speed at the first end 110a of the evaporator 110 is greater than the airflow speed at the second end 110b.

[0053] In accordance with the difference in air flow velocity, this embodiment optimizes the flow area of ​​each water distribution structure 121. Figure 6 , a top view schematic diagram of the water distribution member 120, in this embodiment, the water distribution member 120 and its water distribution structure 121 are both located above the evaporator 110. Among them, the closer to the first end 110a, the larger the flow area of ​​the water distribution structure 121, and the larger the amount of humidification water that the water distribution structure 121 can apply to the corresponding area of ​​the evaporator 110, thereby fully utilizing the evaporation capacity of the evaporator 110 for humidification water, and the closer to the second end 110b, the smaller the flow area of ​​the water distribution structure 121, and the smaller the amount of humidification water that the water distribution structure 121 can apply to the corresponding area of ​​the evaporator 110, thereby avoiding a large amount of humidification water from flowing out of the surface of the evaporator 110 without being evaporated. It can be understood that after the same amount of humidification water is given to the water distribution member 120 and flows out of each water distribution structure 121, the humidification structure provided in this embodiment can evaporate more humidification water, thereby ultimately achieving the purpose of improving the humidification performance of the air conditioner. After actual verification and testing, it was found that the humidification of the entire air conditioner was increased by about 10%. More specifically, in this embodiment, the flow area of ​​each water distribution structure 121 increases in sequence from the first end 110a to the second end 110b.

[0054] The water distribution structure 121 is mainly used to allow humidification water to pass through so that the evaporator 110 is provided with humidification water. Figure 6 In the present embodiment, the water distribution structure 121 is a water distribution hole, and its aperture size determines the size of its flow area. The aperture of the water distribution hole may be above 10 mm, for example, 11 mm or 12 mm, to ensure the water distribution capacity of the water distribution structure 121.

[0055] Implementers may also use a nozzle structure to replace the above-mentioned water distribution holes. For example, in another embodiment, multiple water distribution structures 121 are nozzles of the same specifications, and the nozzles can adjust the opening of their own liquid outlet ends, thereby making the flow areas different from each other. It is understandable that for the technical solution of using a nozzle as the water distribution structure 121, the impeller 182 of the cross-flow fan 180 can be arranged horizontally in the axial direction, and correspondingly, the water distribution member 120 is arranged outside the lateral side of the evaporator 110.

[0056] More specifically, in this embodiment, the projection of each of the water distribution structures 121 on the horizontal plane is covered by the projection of the evaporator 110 on the horizontal plane. This arrangement can ensure that the humidification water entering the water distribution structure 121 directly falls on the evaporator 110, reducing the risk of the humidification water falling outside the evaporator 110.

[0057] In addition, the evaporator 110 can be linear or square, and the implementer can set it according to their own needs. Figure 2 In this embodiment, the projection of the evaporator 110 on the horizontal plane is arc-shaped, and the projection of the crossflow fan 180 on the horizontal plane is outside the side where the projection of the evaporator 110 on the horizontal plane forms an opening. In this way, the evaporator 110 can have a larger heat exchange and humidification area, thereby ensuring heat exchange efficiency and humidification effect.

[0058] See also Figure 5 In this embodiment, the humidification structure 100 further includes:

[0059] The water absorbing body 130 is disposed between the evaporator 110 and the water distributing member 120 to absorb the humidification water flowing out of the water distributing structure 121 and release the humidification water dripping therefrom to the evaporator 110 .

[0060] Among them, during the use of the humidification structure 100, as the humidification water continuously flows out from the water distribution structure 121 of the water distribution member 120, the amount of humidification water that can be adsorbed in the water absorption body 130 reaches the limit. At this time, the humidification water begins to overflow from the water absorption body 130 in a relatively uniform droplet shape, and then drips evenly onto the evaporator 110 to achieve humidification of the airflow. Compared with the related technical solutions, the humidification structure 100 provided in this embodiment mainly utilizes the capillary action of the water absorption body 130 to achieve uniform diffusion of the humidification water, thereby improving the humidification performance of the humidification structure 100.

[0061] As for the material of the water absorbent 130, the implementer can use a sponge material structure or a cotton cloth material structure, both of which have good capillary action and can be effectively applied to the uniform diffusion of humidification water. In this embodiment, the water absorbent 130 is specifically a wet film, which has better humidification water diffusivity than sponge material or cotton cloth material, and can further improve the uniformity of humidification water distribution.

[0062] In addition, please see again Figure 5In this embodiment, the evaporator 110 includes a plurality of fins 111, which are vertically arranged and arranged in sequence in the horizontal direction, and the water absorbing body 130 covers the top of the gap 112 formed between two adjacent fins 111. The gap 112 is mainly used for airflow to pass through, and the fins 111 perform heat exchange operations on the airflow passing through the gap 112. When the water absorbing body 130 directly covers the top of the gap 112, the humidification water can pass through the gap 112. Compared with the related technical solutions, such a setting can improve the contact degree between the airflow and the humidification water, thereby improving the humidification amount of the air conditioner.

[0063] In addition, the distance between the water distribution member 120 and the evaporator 110 in different models of air conditioner indoor units 200 often has certain differences, that is, different models of air conditioners require different thicknesses of the water absorbing body 130. At the same time, the uneven deformation on the water absorbing body 130 will affect the water distribution effect of the water absorbing body 130, and ultimately affect the humidification amount of the air conditioner.

[0064] Therefore, in this embodiment, the water absorbing body 130 is mainly composed of a bendable folding piece 131 , and along the direction from the water distributing member 120 to the evaporator 110 , the folding piece 131 is bent at least once to be in a folded shape.

[0065] Therefore, please refer again to Figure 5 In this embodiment, the water absorbing body 130 is mainly composed of a foldable flap 131, and along the direction from the bottom of the water distributing member 120 to the evaporator 110, the folding flap 131 is folded at least once to be in a folded shape. When installing the indoor unit 200 of the air conditioner, the implementer can first install the water distributing member 120 and the evaporator 110, and then install the water absorbing body 130. In detail, when the distance between the water distributing member 120 and the top of the evaporator 110 is large, the implementer can fold the entire flap 131 for many times to increase the thickness of the entire water absorbing body 130, and when the distance between the water distributing member 120 and the top of the evaporator 110 is small, the implementer can reduce the number of foldings of the flap 131 to reduce the thickness of the water absorbing body 130 finally obtained. After adopting the above arrangement, the installation and arrangement of the water absorbing body 130 can be realized more flexibly. In this embodiment, the water absorbing body 130 is specifically a wet film, and the folding flap 131 is a membrane.

[0066] In addition, for the air conditioner, it is inevitable that there will be some installation errors and manufacturing errors. The error between the evaporator 110 and the water distribution member 120 will eventually cause a small vertical gap 112 to exist between the water absorbing body 130 and the water distribution member 120 or the evaporator 110. Due to the existence of these vertical gaps 112, the humidification water is likely to flow along the surface of the water absorbing body 130 or the water distribution member 120 during its flow, which ultimately affects the uniformity of the water distribution of the entire water absorbing body 130. Therefore, in this embodiment, the two parts of the folding sheet 131 that are bent and folded are the first bending portion 131a and the second bending portion 131b, and the first bending portion 131a and the second bending portion 131b are arranged at an angle.

[0067] By setting the first bending portion 131a and the second bending portion 131b, the water absorbing body 130 is endowed with the ability to elastically expand and contract in the vertical direction, that is, the first bending portion 131a and the second bending portion 131b can be adjusted in such a way that the entire water absorbing body 130 can contract and expand to a certain extent in the vertical direction by adjusting the bending angles of the first bending portion 131a and the second bending portion 131b, thereby allowing the entire water absorbing body 130 to always maintain good contact with the bottom of the water distribution component 120 and the top of the evaporator 110.

[0068] In this embodiment, the water distribution member 120 in the humidification assembly mainly relies on gravity to spontaneously apply humidification water to the water absorbing body 130. In another embodiment, the water distribution member 120 is a water tank. Placing the water tank at a high place will significantly increase the safety risk of the air conditioner. Therefore, please refer to Figure 4 and Figure 7 In this embodiment, the humidification structure 100 further includes:

[0069] a water receiving tray 140, the water receiving tray 140 being disposed at the bottom of the evaporator 110 and being used to receive the humidification water flowing through the evaporator 110;

[0070] a water tank 150, wherein the water tank 150 is configured to receive the humidification water received by the water receiving tray 140;

[0071] A water inlet pipe 160, wherein the water inlet pipe 160 is used to connect the water tank 150 with each of the water distribution structures 121; and

[0072] The pump body 161 is used to guide the humidification water contained in the water tank 150 to enter the water distribution structure 121 .

[0073] The water tank 150 is used to hold the humidification water required for humidification of the air conditioner, and the water receiving tray 140 is used to receive the humidification water that has passed through the ventilation channel and has not yet evaporated. This part of the humidification water flows to the water tank 150 through the connecting pipe 141 and is gathered in the water tank 150. The humidification water gathered in the water tank 150 is transported to the water distribution member 120 under the action of the pump body 161, and thus serves as the humidification water applied by the water distribution structure 121 to the ventilation structure.

[0074] Regarding the pump body 161, it can be set in any component such as the water tank 150 to pull the humidification water. In the present embodiment, the pump body 161 is arranged on the water inlet pipe 160 so that the water inlet pipe 160 attracts the humidification water in the water tank 150 to move upward and finally enter into the water distribution part 120.

[0075] In addition, the implementer can also connect the pump body 161 to the controller to adjust the operating power of the pump body 161, thereby achieving the technical effect of changing the humidity of the airflow. For example, when the ventilation structure is fed with a high air volume, the flow range of the water pump is controlled to be approximately 200ml / h to 700ml / h, that is, the humidification water flows at a high flow rate, so that the humidification water passing through the ventilation channel can be completely evaporated. When the ventilation structure is fed with a low air volume, the flow range of the water pump is controlled to be below 200ml / h to reduce the volume of humidification water that has not been evaporated. This arrangement can avoid the waste of power of the pump body 161 while also reducing the circulating volume of humidification water, reducing the risk of humidification water being contaminated during the circulation of the water tank 150 and the water distribution member 120, thereby improving the cleanliness of the airflow after humidification. It should be pointed out that the above-mentioned controller can be an independent module, or it can be coupled to the control module of the air conditioner itself into the same module.

[0076] For more details, see Figure 8 , a schematic diagram of the air conditioner indoor unit 200 disassembling the lower part of the shell to reveal the evaporator 110, it can be seen that in this embodiment, the humidification structure 100 also includes an evaporator bracket 170, and the evaporator bracket 170 specifically includes an upper evaporator bracket 171 and a lower evaporator bracket 172, the evaporator 110 is arranged between the upper evaporator bracket 171 and the lower evaporator bracket 172, and the water distribution member 120 forms an integrated structure with the upper evaporator bracket 171, and the lower evaporator bracket 172 forms an integrated structure with the water receiving tray 140. The implementer can also set the water distribution member 120, the upper evaporator bracket 171, the water receiving tray 140, and the lower evaporator bracket 172 to be independent of each other.

[0077] Furthermore, in this embodiment, the air conditioner indoor unit 200 has a shell, on which a return air port 220 and an air outlet 210 are formed, and the humidification structure 100 is arranged between the return air port 220 and the air outlet 210 of the air conditioner, so as to humidify the conditioned air while the air conditioner indoor unit 200 is supplying air normally. The implementer can also configure the humidification structure 100 to be independent of the air supply structure of the air conditioner indoor unit 200, that is, a humidification channel independent of its air supply channel is formed on the air conditioner indoor unit 200, and the humidification structure 100 is arranged in the humidification channel.
