DETAILED DESCRIPTION

[0040] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0041] The technical solution of this implementation mode is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples can be combined with each other if there is no conflict.

[0042] like Figure 1-Figure 15As shown, this embodiment proposes an air conditioner indoor unit, which can be a wall-mounted air conditioner indoor unit or a cabinet-type air conditioner indoor unit. The air conditioner indoor unit includes a housing 1, a cross-flow fan 104 and a humidification component. Figure 1 As shown in FIG. 7 , the housing 1 is provided with an air outlet 12 and a first air inlet 11, and an air outlet duct 2 is provided inside the housing 1, and the air outlet end of the air outlet duct 2 is connected to the air outlet 12. The cross-flow fan 104 is provided at the air inlet end of the air outlet duct 2, and the humidification component is provided in the housing 1, as shown in FIG. Figure 3 As shown in FIG. 7 , the humidifying assembly includes a mist outlet 7 and an atomizing device 6. The mist outlet 7 includes a mist outlet body 71. The mist outlet body 71 is provided with a mist inlet 711, a mist outlet 712 and a second air inlet 713. The atomizing device 6 is connected to the mist inlet 711 through a mist outlet pipe 8. The mist outlet 712 is connected to the second air inlet 713. Figure 7c The opening part framed by the dotted line.

[0043] An internal passage 714 is provided in the mist outlet body 71, which connects the mist inlet 711, the mist outlet 712 and the second air inlet 713. The second air inlet 713 and the mist outlet 712 respectively connect the internal passage 714 with the interior of the housing 1. The airflow in the housing 1 can enter the internal passage 714 through the second air inlet 713, and the airflow and water mist in the internal passage 714 can be discharged through the mist outlet 712. When the air conditioner indoor unit is in humidification mode, part of the airflow entering the housing 1 through the first air inlet 11 can enter the internal passage 714 through the second air inlet 713 under the action of the cross-flow fan 104, and be sprayed out through the mist outlet 712 along with the mist entering the internal passage 714 through the mist inlet 711. The mist sprayed out from the mist outlet 712 enters the cross-flow fan 104, and is blown out from the air outlet 12 through the air outlet duct 2 under the action of the cross-flow fan 104, so as to humidify the indoor ambient air.

[0044] In this embodiment, the second air inlet 713 is provided to ensure the air pressure balance in the mist outlet head body 71, to ensure the reliability of the mist outlet head 7, and the water mist and the air flow are pre-mixed in the internal passage 714, thereby improving the uniform mixing effect of the water mist and the air flow in the air outlet duct 2. In addition, the air flow entering the internal passage 714 from the second air inlet 713 will also generate an impact force on the water mist in the internal passage 714, thereby further breaking up the water mist, reducing the droplet size, and significantly improving the humidification effect.

[0045] In this embodiment, the location of the mist outlet head 7 is not specifically limited and can be flexibly designed according to needs. Figure 5 , Figure 6a-Figure 6bThe structure diagram of the indoor unit of the air conditioner is shown, and the indoor unit of the air conditioner includes an indoor heat exchanger 3, which is arranged in the housing 1 and is located in the air flow path between the first air inlet 11 and the crossflow fan 104. The indoor heat exchanger 3 includes a plurality of fins and a plurality of heat exchange tubes 31, and the plurality of fins are stacked, and the plurality of heat exchange tubes 31 penetrate the plurality of fins. The mist outlet head 7 can be arranged between the crossflow fan 104 and the indoor heat exchanger 3, and can also be directly arranged in the air outlet duct 2.

[0046] In a preferred embodiment, Figure 5 , Figure 6a , Figure 6b As shown, the mist outlet body 71 is arranged on the windward side of the indoor heat exchanger 3, and the mist outlet 712 is arranged on the side of the mist outlet body 71 close to the indoor heat exchanger 3. Under the action of the negative pressure formed by the high-speed rotation of the cross-flow fan 104, the mist discharged from the mist outlet 712 is driven to enter the cross-flow fan 104 through the indoor heat exchanger 3, and under the action of the cross-flow fan 104, the mist is fully mixed with the air flow in the air outlet duct 2, and then blown out from the air outlet 12 with appropriate humidity, thereby improving the comfort of the indoor environment.

[0047] In this embodiment, the mist outlet body 71 is arranged on the windward side of the indoor heat exchanger 3. When the air conditioner indoor unit operates in the heating mode and the humidification is turned on, at the initial stage of heating, the water mist sprayed by the mist outlet 7 adheres to the fins of the indoor heat exchanger 3 to form condensation to release latent heat and improve the air conditioning effect. As the heating mode is running, the indoor ambient temperature rises, the indoor return air enters the shell 1 through the first air inlet 11, and part of the air flow in the shell 1 enters the internal passage 714 of the mist outlet 7 through the second air inlet 713. When the indoor return air with a certain temperature is sprayed out from the mist outlet 712 with the water mist, the water mist can be reduced from adhering to the fins of the indoor heat exchanger 3, thereby reducing the generation of condensation. On the other hand, when the air conditioner indoor unit operates in the self-cleaning mode, the water mist sprayed by the mist outlet 7 adheres to the fins of the indoor heat exchanger 3, which can humidify the fins, thereby increasing the thickness of the frost layer required for the self-cleaning process of the fins and improving the self-cleaning effect. Placing the mist outlet 712 opposite to the indoor heat exchanger 3 can shorten the water mist flow path, reduce water mist loss, and ensure the humidification effect on the airflow. In addition, when the mist outlet body 71 is arranged on the windward side of the indoor heat exchanger 3, the second air inlet 713 is arranged to ensure the air intake of the indoor heat exchanger 3, avoiding the situation where the mist outlet body 71 is arranged on the windward side of the indoor heat exchanger 3 and blocks the airflow from entering the indoor heat exchanger 3.

[0048] In one example, if Figure 6aAs shown, the indoor heat exchanger 3 is half-surrounded by the outer periphery of the cross-flow fan 104, and the indoor heat exchanger 3 includes a first heat exchange section 32, a second heat exchange section 33 and a third heat exchange section 34 which are connected in sequence, a first angle is formed between the first heat exchange section 32 and the second heat exchange section 33, and a second angle is formed between the second heat exchange section 33 and the third heat exchange section 34, the first heat exchange section 32 is far away from the air outlet 12, and the third heat exchange section 34 is close to the air outlet 12, and the mist outlet head body 71 is arranged on the windward side of the third heat exchange section 34.

[0049] The indoor heat exchanger 3 of this embodiment is half-surrounded by the outer periphery of the cross-flow fan 104 in the circumferential direction, which not only increases the heat exchange area of ​​the indoor heat exchanger 3, but also ensures that the airflow entering the housing 1 from the first air inlet 11 is sucked into the cross-flow fan 104 after heat exchange through the indoor heat exchanger 3, thereby ensuring the air conditioning effect. The mist outlet body 71 is arranged on the windward side of the third heat exchange section 34 close to the air outlet 12, which can reduce the loss of water mist and ensure the humidification effect.

[0050] The present embodiment does not limit the location of the air outlet 12 and the first air inlet 11. The air outlet 12 may be located at the upper part, lower part or front part of the housing 1, and the first air inlet 11 may be located at the upper part, front part, lower part or rear part of the housing 1. The location of the air outlet 12 on the housing 1 may be determined according to the type of the indoor unit of the air conditioner. Figure 3-Figure 5 As shown, the indoor unit of the air conditioner is a hanging unit, and the hanging height of the hanging unit is 20cm-60cm. At this time, the air outlet 12 is arranged at the upper part of the front side of the housing 1, and the first air inlet 11 is arranged at the lower part of the housing 1. The air inlet direction is referenced Figure 5 The direction indicated by the arrow. The humidification component also includes a water tank 5, which is detachably arranged at the upper part of the internal space of the shell 1. The atomizer 6 is arranged at one end of the axial direction of the cross-flow fan 104. The water inlet end of the atomizer 6 is connected to the water tank 5. The mist outlet pipe 8 connects the mist outlet end of the atomizer 6 to the mist inlet 711 of the mist outlet head body 71 from one side of the windward side of the indoor heat exchanger 3. At this time, the airflow with appropriate temperature and humidity blown out from the air outlet 12 is directly blown onto the user's body, making the user feel comfortable. The air inlet is arranged at the bottom of the shell 1 to accelerate the heat exchange of the bottom airflow. In addition, setting the air conditioner indoor unit at this height can facilitate the user to add water to the water tank 5 connected to the atomizer 6.

[0051] In some embodiments, Figure 3 As shown in FIG. 7 , the mist outlet 712 extends along the axial direction of the cross-flow fan 104 . At this time, the mist outlet 712 is in a long strip shape, which can disperse the water mist and improve the uniformity of the distribution of the water mist in the air outlet duct 2 .

[0052] In some embodiments, Figure 7a-7cAs shown, there are multiple second air inlets 713, and the multiple second air inlets 713 are spaced apart along the axial direction of the cross-flow fan 104, so as to ensure the structural strength of the mist outlet body 71 while ensuring the reliability of the mist outlet body 71 while ensuring the air intake of the mist outlet head 7.

[0053] In some embodiments, Figure 6a , Figure 7a-7c As shown, the second air inlet 713 is disposed on the top and / or side of the mist outlet body 71 to prevent condensed water in the mist outlet body 71 from flowing out through the second air inlet 713 .

[0054] In some embodiments, Figure 6a and Figure 6b As shown, the side of the mist outlet body 71 away from the indoor heat exchanger 3 is tilted from top to bottom toward the direction close to the indoor heat exchanger 3, which reduces the air flow resistance from the first air inlet 11 to the second air inlet 713, and guides the condensed water in the mist outlet body 71 to the indoor heat exchanger 3 from the mist outlet 712, or guides the condensed water outside the mist outlet body 71 to the indoor heat exchanger 3, and the condensed water will flow along the indoor heat exchanger 3 to the water receiving tank 601 located at the bottom of the indoor heat exchanger 3. At the same time, the volume of the mist outlet body 71 is also reduced.

[0055] In some embodiments, Figure 6b , Figure 7a-7c As shown, the mist outlet head 7 includes a fixing component, which is arranged on the mist outlet head body 71, and is used to detachably set the mist outlet head body 71 on the indoor heat exchanger 3. There is no limitation on the setting method of the fixing component, for example, the fixing component includes a combination of one or more of a connector, a snap-in connector, and a plug-in connector. In one example, the fixing component includes at least one support plate 715, one end of the support plate 715 is connected to the mist outlet head body 71, and the other end is provided with a slot 716, and one end of the support plate 715 provided with the slot 716 is inserted into the gap between any two adjacent fins of the indoor heat exchanger 3, and the slot 716 is snap-fitted with the heat exchange tube 31 of the indoor heat exchanger 3.

[0056] In this embodiment, the slot 716 is directly engaged with the heat exchange tube 31, thereby reducing the gap between the mist outlet body 71 and the indoor heat exchanger 3, so that the mist outlet body 71 fits the indoor heat exchanger 3, and reduces the overflow of water mist from the gap between the mist outlet body 71 and the mist outlet 7. In addition, the mist outlet body 71 is directly engaged with the heat dissipation tube of the indoor heat exchanger 3 through the slot 716, which simplifies the installation process, and at the same time, there is no need to set additional fixings on the indoor heat exchanger 3, thereby reducing the production cost.

[0057] In a preferred embodiment, Figure 7a-7cAs shown, support plates 715 are provided at both ends of the mist outlet body 71 along the axial direction of the cross-flow fan 104, and two card slots 716 are provided at the end of each support plate 715 away from the mist outlet body 7, and the two support plates 715 are respectively inserted into the gap between two adjacent fins, and the two card slots 716 are clamped with the two heat exchange tubes 31, thereby improving the reliability of the assembly between the mist outlet body 71 and the indoor heat exchanger 3.

[0058] In some embodiments, Figure 7a-7c As shown, a side of the mist outlet body 71 facing the indoor heat exchanger 3 is provided with a positioning rib 717 and one of the positioning grooves, and a position corresponding to the indoor heat exchanger 3 and the mist outlet body 71 is provided with a positioning rib 717 and the other of the positioning grooves, and the positioning rib 717 is positioned and matched with the positioning groove. In this embodiment, the indoor heat exchanger 3 and the mist outlet body 71 are positioned and matched with the positioning rib 717 and the positioning groove, thereby improving the assembly efficiency between the mist outlet body 71 and the indoor heat exchanger 3.

[0059] In some embodiments, Figure 2 As shown, the air conditioner indoor unit is also provided with a humidity detector 102 for detecting the humidity of the indoor environment.
