Therefore, the utility model discloses technical scheme is favorable to promoting the heat exchange efficiency of air conditioner, saves the air conditioner inner space, is favorable to the product miniaturization to the limited board house of adaptation inner space.

Further, as shown in fig. 4 and 5, a volute 210 and a volute tongue 220 are arranged in the internal machine casing 100, the volute 210 and the volute tongue 220 are located on the air inlet side of the indoor side wind wheel 200 and are arranged into the air inlet duct, so that the air flow is concentrated to enter from the air inlet duct, the air inlet pressure is increased, the volute 210 and the volute tongue 220 are arranged into the air outlet duct on the air outlet side of the indoor side wind wheel 200 and are arranged into the air outlet duct, so that the air flow is concentrated to blow out from the air outlet duct, and the air outlet pressure is increased. In this embodiment, the distance between the volute 210 and the volute tongue 220 gradually increases from the center of the indoor wind wheel 200 to the indoor air inlet 111, so as to provide wide-angle air inlet; in addition, the distance between the volute 210 and the volute tongue 220 is gradually increased from the center of the indoor wind wheel 200 to the indoor air outlet 112, so as to output air in a wide angle. Certainly, in other embodiments, the distance between the volute 210 and the volute tongue 220 may also be kept unchanged from the center of the indoor side wind wheel 200 to the direction of the indoor side air outlet 112, so that the air volume flowing through the heat exchanger can be increased, and the heat exchange efficiency is further improved. It should be noted that, in this embodiment, the upper and lower ends of the indoor side heat exchanger 300 are respectively connected to the volute and the volute 210, so that the volute 210, the volute tongue 220 and the indoor side heat exchanger 300 enclose an air chamber, thereby ensuring that the airflow can smoothly enter the air duct after passing through the indoor side heat exchanger 300 for heat exchange. In addition, in this embodiment, the lower end of the indoor heat exchanger 300 abuts against the bottom of the indoor unit casing 100, and the lower end of the volute 210 abuts against the lower end of the indoor heat exchanger 300, so that after the airflow enters the indoor unit casing 100 through the indoor air inlet 111, the airflow can completely flow through the indoor heat exchanger 300 to exchange heat, and the airflow is prevented from escaping from between the indoor heat exchanger 300 and the bottom of the indoor unit casing 100.

Further, as shown in fig. 4, the indoor side heat exchanger 300 includes a first heat exchanging portion 310 and a second heat exchanging portion 320, and the first heat exchanging portion 310 and the second heat exchanging portion 320 are disposed at an included angle, so as to facilitate the height of the indoor side heat exchanger 300 to be compressed, and meanwhile, the heat exchange area of the indoor side heat exchanger 300 can be increased, thereby improving the heat exchange efficiency. In addition, the indoor heat exchanger 300 is divided into two heat exchange portions, and the heat exchange flow paths of the two heat exchange portions may not be communicated with each other, so that the length of the heat exchange flow path can be shortened, thereby reducing heat loss in the flow process of the refrigerant and improving heat exchange efficiency. Of course, in other embodiments, the indoor-side heat exchanger 300 may not be provided in sections or in more than three sections.

Further, the included angle opening that forms between first heat transfer portion 310 and the second heat transfer portion 320 faces indoor side wind wheel 200, so, the area of crossing the wind that is equivalent to increase the wind channel import reduces the windage, and wide angle formula air inlet further increases the intake. And the angle of the included angle is larger than 90 degrees, so that the heat exchange surfaces of the two heat exchange parts correspond to the indoor side air inlet 111 as much as possible, and the air can fully flow through the two heat exchange parts to exchange heat.

Further, as shown in fig. 4, the first heat exchanging part 310 extends vertically, and the second heat exchanging part 320 is connected to a lower end of the first heat exchanging part 310 and is inclined inward with respect to the first heat exchanging part 310. That is, the second heat exchanging part 320 is inclined with respect to the vertical direction, so that the occupied space of the second heat exchanging part 320 in the vertical direction can be reduced, and the lateral space of the air conditioner can be sufficiently utilized. Under the condition of ensuring that the whole heat exchange area of the indoor side heat exchanger 300 is unchanged, the utilization rate of the inner space of the air conditioner is effectively improved, the structure of the whole air conditioner is more compact, and the height size of the whole air conditioner can be reduced.

That is, the angle of inclination of the air intake side of the second heat exchanging part 320 with respect to the air intake side of the first heat exchanging part 310 is greater than or equal to 30 ° and less than or equal to 60 °. It should be understood that if the inclination angle of the second heat exchanging portion 320 is too large, the vertical air inlet area of the second heat exchanging portion 320 is greatly reduced, and thus the effective air inlet area of the second heat exchanging portion 320 is greatly reduced. For example, when the inclination angle of the second heat exchanging portion 320 is greater than 60 °, the effective air inlet area of the second heat exchanging portion 320 is reduced by more than 50%, which may seriously affect the heat exchange efficiency. In addition, when the inclination angle of the second heat exchanging part 320 is too large, the condensed water generated by the first heat exchanging part 310 is easily dropped from the bottom of the case directly, which may generate a large noise and affect the use of the user. When the inclination angle of the second heat exchanging portion 320 is too small, it is difficult to achieve the effect of fully utilizing the lateral space of the air conditioner, so that the indoor side heat exchanger 300 occupies a large space in the vertical direction, and the height of the air conditioner is increased.

This embodiment is through the inclination setting with second heat transfer portion 320 when between 30 to 60, can solve above-mentioned problem betterly, can enough make full use of air conditioner horizontal space, effectively promotes the utilization ratio of air conditioner inner space, still guarantees that second heat transfer portion 320 has great effective air inlet area, guarantees heat exchange efficiency.
