In this embodiment, the windward side 312 of the indoor heat exchanger 310 refers to the windward side of the tube bundle of the indoor heat exchanger 310. When the indoor heat exchanger 310 is a U-shaped tube plate heat exchanger, the windward side 312 refers to a side of the indoor heat exchanger 310 facing the indoor air inlet or windward. The fresh air inlet 411 and the fresh air outlet 412 may be rectangular, circular, elongated, oval, or may be a plurality of micro-holes, which is not limited herein. It should be noted that the fresh air duct 413 is an air duct independent from the indoor side air duct, that is, the air flows in the two air ducts do not interfere with each other. The fresh air outlet 412 is disposed adjacent to the windward side 312 of the indoor heat exchanger 310, and the distance between the fresh air outlet 412 and the windward side 312 of the indoor heat exchanger 310 is less than or equal to 10% of the thickness of the indoor heat exchanger 310. The fresh air outlet 412 may be flush with the windward side 312 of the indoor side heat exchanger 310 or such that the fresh air outlet 412 is disposed to protrude from the windward side 312 of the indoor side heat exchanger 310. That is, the end of the fresh air case 410 is made flush with the windward side 312 of the indoor side heat exchanger 310 or is disposed to protrude from the windward side 312 of the indoor side heat exchanger 310. Therefore, the fresh air duct 413 can directly extend to the windward side 312 of the indoor heat exchanger, and dehumidification of fresh air through the indoor heat exchanger 310 is facilitated. The end of the fresh air casing 410 may not extend out of the windward side 312 of the indoor heat exchanger 310, and the fresh air outlet 412 may be adjacent to the windward side 312 of the indoor heat exchanger 310. At this time, the fresh air blown out from the fresh air outlet 412 can flow along the side wall 311 of the indoor heat exchanger 310, the side wall 311 of the indoor air duct casing 500, or the side wall 311 of the cabinet 200 and blow toward the windward side 312 of the indoor or indoor heat exchanger 310.
By arranging the fresh air outlet 412 adjacent to the windward side 312 of the indoor heat exchanger 310, the airflow blown out from the fresh air outlet 412 can be quickly sucked into the indoor air duct by the indoor fan, and dehumidified by the indoor heat exchanger 310. Most of the air flow blown out from the fresh air outlet 412 can be dehumidified by the indoor heat exchanger 310 before being fully mixed with the indoor air flow, so that the situation that the humidity and the temperature in the room are affected after the fresh air which is not dehumidified enters the room and is mixed with the indoor air flow can be effectively avoided, and the use comfort of a user is further improved. And indoor wind wheel can inhale indoor wind and the new trend that blows off from new trend export 412 in the indoor side wind channel together, and through indoor side wind channel dehumidification, so, not only dehumidify the new trend, reduced the influence of new trend to indoor wind, and make the air current in whole house only can dehumidify to increase dehumidification efficiency.
Further, as shown in fig. 2 and 4, the fresh air casing 410 has an air outlet section 414 protruding from the windward surface 312 of the indoor side heat exchanger 310, the end of the air outlet section 414 is bent toward the end of the indoor side heat exchanger 310 opposite to the side wall 311, and a fresh air outlet 412 is formed at the end of the air outlet section 414.
In this embodiment, it can be understood that the air outlet section 414 protrudes from the windward surface 312 of the indoor side heat exchanger 310, that is, the air outlet section 414 protrudes from the windward surface of the indoor side heat exchanger 310 closest to the indoor air inlet side, that is, the air outlet section 414 protrudes from the outdoor side to the indoor side to protrude the entire indoor side heat exchanger 310. When the indoor side heat exchanger 310 includes two indoor heat exchangers stacked in a front-back manner, the air outlet section 414 protrudes out of the windward side 312 of the indoor heat exchanger on the front side, i.e., the side close to the indoor air outlet. The air outlet section 414 may be disposed inside the casing 200 or outside the casing 200. When the air outlet section 414 is disposed in the casing 200, the indoor heat exchanger 310 and the front side wall 311 of the casing 200 are disposed at an interval, and the air outlet section 414 is located between the indoor heat exchanger 310 and the front side wall 311 of the casing 200 and is communicated with the indoor air inlet 210, so that a gap between the indoor heat exchanger 310 and the front side wall 311 of the casing 200 can be utilized, and fresh air blown out from the air outlet section 414 can be blown to the indoor heat exchanger 310 quickly for heat exchange. When the air outlet section 414 of the fresh air casing 410 is disposed outside the casing 200, the indoor heat exchanger 310 can be directly attached to the front side wall 311 of the casing 200, and then the airflow entering from the indoor air inlet 210 can directly enter the indoor heat exchanger 310, thereby improving the heat exchange efficiency. And the air outlet section 414 is arranged outside the casing 200, which can improve the fresh air circulation rate, thereby ensuring enough fresh air volume.
Through making the end of air-out section 414 buckle towards the opposite end of indoor side heat exchanger 310 and its lateral wall 311, then can change the orientation of new trend export 412 and the size of new trend export 412, and make new trend export 412 more press close to the middle part of the windward side 312 of indoor side heat exchanger 310, and then promote dehumidification effect. It can be understood that the bending of the end of the air outlet section 414 may be a single-section bending, or may be a multi-section bending, and the number and direction of the bending sections may be selected according to actual requirements, which is not specifically limited herein. In order to increase the air output, the end of the air output section 414 may be gradually expanded toward the fresh air outlet 412.
In one embodiment, referring to fig. 3 and 4, the opening of the fresh air outlet 412 is disposed forward. Thus, the structure of the air outlet section 414 of the fresh air case 410 can be simplified while the dehumidification requirement is satisfied. In another embodiment, the opening of the fresh air outlet 412 is disposed toward the windward side 312 of the indoor side heat exchanger 310. Therefore, fresh air blown out from the fresh air outlet 412 can immediately enter the indoor side heat exchanger 310 for dehumidification, and the influence of the fresh air on indoor airflow is reduced while the fresh air intake is met. In other embodiments, the fresh air outlet 412 opens toward an end of the cabinet 200 that is away from the fresh air case 410 in the left-right direction. In this way, the gap between the indoor heat exchanger 310 and the front wall 311 of the casing 200 can be fully utilized, the circulation rate of the fresh air can be increased, the airflow blown out from the fresh air outlet 412 can circulate along the windward side 312 of the indoor heat exchanger, and the fresh air blown out from the fresh air outlet 412 can rapidly enter the indoor heat exchanger 310 for dehumidification.
In one embodiment, as shown in fig. 2, 3 and 5, the fresh air outlet 412 extends in the vertical direction. By extending the fresh air outlet 412 in the vertical direction, the space in the height direction in the machine case 200 is fully utilized, the fresh air outlet amount is further increased, and the occupied space of the fresh air case 410 in the left and right directions is small, so that the whole structure is more compact.
Further, the extension length of the fresh air outlet 412 is greater than or equal to one third of the height of the side wall 311 of the indoor side heat exchanger 310, and is less than or equal to the height of the side wall 311 of the indoor side heat exchanger 310. Specifically, the extension length of the fresh air outlet 412 may be one third, one half, two thirds, five sixths, and the like of the height of the side wall 311 of the indoor side heat exchanger 310. When the extension length of the fresh air outlet 412 is less than one third of the height of the side wall 311 of the indoor side heat exchanger 310, the air outlet area of the fresh air outlet is small, and the requirement of the fresh air outlet volume cannot be met. When the extension length of the fresh air outlet 412 is greater than the height of the side wall 311 of the indoor side heat exchanger 310, the height of the air outlet section 414 of the fresh air casing 410 is too high, so that the height of the whole machine needs to be increased, and the volume of the whole machine is increased. By enabling the extension length of the fresh air outlet 412 to be greater than or equal to one third of the height of the side wall 311 of the indoor side heat exchanger 310 and smaller than or equal to the height of the side wall 311 of the indoor side heat exchanger 310, the requirement of fresh air output volume is met on the premise that the height of the whole machine is not increased.
