Specifically, in this embodiment, the casing 100 of the indoor unit of the air conditioner may be formed by one-piece molding, or may be formed by splicing a plurality of parts, and has an air inlet through which air flows into the indoor unit of the air conditioner and an air outlet through which air flows out of the indoor unit of the air conditioner. The heat exchange component and the air duct 110 component of the indoor unit of the air conditioner are arranged in the air duct 110. The heat exchanging component includes a heat exchanger 300, the air duct 110 component includes a wind wheel 200, and the positional relationship between the two components can be various, for example, the heat exchanger 300 is disposed in the air duct 110 between the wind wheel 200 and the air inlet, or disposed in the air duct 110 between the wind wheel 200 and the air outlet, and the description will be given by taking the example that the wind wheel 200 is located between the heat exchanger 300 and the air inlet. The first dehumidifying heat exchanger 310 may have a plurality of overall shapes, such as a flat plate shape, a bent plate shape, etc., and the first dehumidifying heat exchanger 310 may be integrally disposed or may be disposed in a sectional shape. Similarly, the overall shape of the first heating heat exchanger 320 may be many, such as a flat plate, a bent plate, etc., and the first heating heat exchanger 320 may be integrally disposed or may be disposed in a sectional manner.
In this embodiment, when the airflow passes through the first dehumidifying heat exchanger 310, the airflow exchanges heat with the airflow to obtain cold energy, and the moisture in the airflow is condensed to form condensed water and flows downwards along the first dehumidifying heat exchanger 310, so that the moisture in the airflow can be removed and the airflow can be dried. When the air flow passes through the first heating heat exchanger 320, the air flow exchanges heat with the air flow to obtain heat energy, so as to increase the temperature of the air flow. The air current with higher temperature flows upwards, and the air current with lower temperature flows downwards, so that the cold air and the hot air flow are mixed in the air duct 110, the mixed air temperature is moderate, the temperature difference with the air outside the air conditioner is small (compared with the cold air and the hot air flow which are not mixed, and the direct comparison with the indoor air is carried out), when the mixed air and the indoor air are mixed again, the condensate water cannot be formed at the position of the air outlet due to the large temperature difference, and the use of the air conditioner by a user is facilitated.
The arrangement of the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 is many, and will be described in detail below:

The longitudinal directions of the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 correspond to the longitudinal direction of the casing 100, and extend in the longitudinal direction of the casing 100. The first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 are spliced (with a gap left therebetween) in the height direction or the width direction of the casing 100. The spliced heat exchanger 300 may be vertically disposed in the air duct 110 or may be obliquely disposed in the air duct 110.
In other embodiments, the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 are disposed at an included angle, and the opening of the included angle faces the wind outlet direction of the wind wheel 200. So set up, the fin of top and bottom and the distance between the wind wheel 200 air outlet are less than the fin in middle part and the distance between the wind wheel 200 export. That is, the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 are inclined and extended to the middle part, part of the air flow is guided to the middle part of the first dehumidifying heat exchanger 310 by the top of the first dehumidifying heat exchanger 310 for heat exchange, part of the air flow is guided to the middle part of the first heating heat exchanger 320 for heat exchange by the bottom of the first heating heat exchanger 320, and meanwhile, the area of the heat exchanger is increased by the inclined arrangement, which is beneficial to improving the heat exchange efficiency of the air flow.
In other embodiments, the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 are disposed at an included angle, and the opening of the included angle faces the wind outlet direction away from the wind wheel 200. So set up, the fin of top and bottom and the distance between the wind wheel 200 air outlet are greater than the fin in middle part and the distance between the wind wheel 200 export. The first dehumidifying heat exchanger 310 extends from the middle of the air duct 110 to the top, and the first heating heat exchanger 320 extends from the middle of the air duct 110 to the lower side.

The top of the first dehumidifying heat exchanger 310 is far away from the air outlet, so that the wind speed passing through the top of the first dehumidifying heat exchanger 310 can be effectively reduced, and meanwhile, partial airflow at the top is diffused towards the first dehumidifying heat exchanger 310 (fluid is diffused under the action of pressure difference and downward diffusion of cold airflow characteristics), so that the heat exchange efficiency of the first dehumidifying heat exchanger 310 is improved.
Similarly, the flow rate of the air flow between the bottom of the first heating heat exchanger 320 and the casing 100 is larger than the flow rate of the air flow passing through the first heating heat exchanger 320 due to installation requirements or process errors of parts (precision). The bottom of the first heating heat exchanger 320 is far away from the air outlet, so that the wind speed passing through the bottom of the first heating heat exchanger 320 can be effectively reduced, and meanwhile, partial airflow at the bottom is diffused to the first heating heat exchanger 320 (fluid is diffused under the action of pressure difference and upwards diffused by hot airflow characteristics), so that the heat exchange efficiency of the first heating heat exchanger 320 is improved.
In some embodiments, in order to improve the heat exchange efficiency, the heat exchanger 300 further includes a second heating heat exchanger 330, and the second heating heat exchanger 330 is disposed above the first heating heat exchanger 320 and below the first dehumidifying heat exchanger. The second heating heat exchanger 330 is disposed between the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320, so that the air flow after heat exchange with the second heating heat exchanger 330 still flows upwards to be mixed with the air flow after heat exchange with the first dehumidifying heat exchanger 310.
In some embodiments, to further improve the heat exchange efficiency and improve the mixing degree of the cold and hot air flows, the heat exchanger 300 further comprises a second dehumidifying heat exchanger 340, and the second dehumidifying heat exchanger 340 is located between the second heating heat exchanger 330 and the first dehumidifying heat exchanger 310; alternatively, the second dehumidifying heat exchanger 340 is located between the first heating heat exchanger 320 and the second heating heat exchanger 330. Through setting up a plurality of dehumidification heat exchangers and heating heat exchanger, compare in only setting up a dehumidification heat exchanger and heating heat exchanger respectively, be favorable to reducing the distance of heat transfer back air current in limited space, be favorable to the mixture of air current more. Particularly, when the second dehumidifying heat exchanger 340 is disposed between the first heating heat exchanger 320 and the second heating heat exchanger 330, the air flow after exchanging heat with the second dehumidifying heat exchanger 340 can be simultaneously mixed with the air flow after exchanging heat with the first heating heat exchanger 320 and the second heating heat exchanger 330, and simultaneously, the air flow after exchanging heat with the second heating heat exchanger 330 can be simultaneously mixed with the air flow after exchanging heat with the first dehumidifying heat exchanger 310 and the second dehumidifying heat exchanger 340, so that the mixing of the air flow after exchanging heat with the heat exchanger 300 can be greatly improved, thereby reducing the formation of condensed water at the position of the air outlet.
It should be noted that all the above heat exchangers (the first dehumidifying heat exchanger 310, the second dehumidifying heat exchanger 340, the first heating heat exchanger 320, the second heating heat exchanger 330, and further heat exchangers additionally provided as necessary) may be independent heat exchangers. In some embodiments, it may be integral, or portions thereof.

In this embodiment, the water tray 400 disposed between the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 is taken as an example. The first dehumidifying heat exchanger 310 condenses the water vapor by cooling, and then flows into the water pan 400 along the fins of the first dehumidifying heat exchanger 310. The drain pan 400 then drains the condensed water out of the indoor unit of the air conditioner.
It should be noted that, in this embodiment, the water receiving tray 400 not only has the function of receiving the condensed water, but also has the function of guiding the airflow. In general, the amount of air passing through the joint of the first dehumidifying heat exchanger 310 and the first heating heat exchanger 320 is large, but in the present embodiment, the water pan 400 is disposed therebetween, and when the air flows toward the joint of the two, the pan wall 410 on the windward side of the water pan 400 blocks and guides the air flow toward the first dehumidifying heat exchanger 310 or the first heating heat exchanger 320. The quantity of the air flow passing through the joint of the air flow and the air flow is greatly reduced, and the guided air flow exchanges heat, so that the constant-temperature dehumidification effect is favorably improved.

The bottom of the first dehumidifying heat exchanger 310 is arranged in the water receiving tray 400, so that the air flow can not blow out the condensed water out of the water receiving tray 400, and the reliability of receiving the condensed water is effectively guaranteed. By setting the tray wall 410 on the windward side higher than the tray wall 420 on the leeward side, the water pan 400 (the windward tray wall 410) can efficiently guide the airflow to the first heating heat exchanger 320 and/or the first dehumidifying heat exchanger 310, and can smoothly pass through the joint between the two (because the tray wall 420 on the leeward side is lower, the airflow cannot be blocked).
In some embodiments, in order to better exchange heat with the heat exchanger 300 for improving the constant temperature dehumidification effect, the casing 100 is further provided with a wind guide portion 500, and the wind guide portion 500 is located on the side wall of the wind channel 110 between the wind outlet of the wind wheel 200 and the heat exchanger 300, so as to guide the airflow on the side wall of the wind channel 110 to the middle of the wind channel 110. The wind guiding portion 500 is exemplified by a wind guiding block, which is arranged in a wedge shape and extends from one end close to the wind wheel 200 to one end close to the heat exchanger 300, and extends from the side wall of the wind channel 110 to the middle of the wind channel 110. So that the air flow extends from the side wall of the air duct 110 to the middle of the air duct 110, thereby greatly reducing the air flow lost between the heat exchanger 300 and the side wall of the air duct 110, and being beneficial to improving the constant temperature dehumidification effect of the indoor unit of the air conditioner.
