Detailed Description
With reference to fig. 1 to 2, according to an embodiment of the present invention, an air-conditioning indoor unit, especially a wall-hanging air-conditioning indoor unit, is provided, including a casing 1, an air inlet 11 is configured on a bottom wall of the casing 1, an air outlet 12 is configured on a front side wall of the casing 1, the casing 1 has an air duct casing, the air duct casing includes a volute tongue casing 21 and a volute casing 22, the volute tongue casing 21 has a volute tongue 211, and the volute tongue 211 is located below the volute casing 22 and is adjacent to the air outlet 12. In the technical scheme, while the lower air outlet in the prior art is improved and set as the upper air outlet 12, the volute tongue 211 is arranged at the lower side of the volute casing 22, so that the vortex core position of the flow field in the cross-flow fan 4 of the indoor unit of the air conditioner is moved to the area adjacent to the lower side of the air outlet 12, and the air pressure in the area is low, thus the air flow flowing out of the cross-flow fan 4 can be deviated to the area with low air pressure, the air outlet flow can flow out by clinging to the volute tongue 211, the air outlet flow of the air outlet 12 is ensured to have a downward flowing trend when flowing out of the air outlet 12, and the landing performance of the air outlet flow of the air conditioner is improved; furthermore, due to the adoption of the air inlet 11 positioned at the lower part, the air inlet airflow of the air inlet is adaptive to the position of the volute tongue 211, so that the air inlet of the air inlet can be more concentrated at one side close to the front side wall of the shell 1 and far away from one side of the installation wall. At this time, it is preferable that the air guide plate 3 is disposed at the air outlet 12, one side of the air guide plate 3 is connected (hinged) to one side of the air outlet 12, when the air conditioner operates, the air guide plate 3 can guide a flow direction of an outlet airflow, and when the air conditioner stops operating, the air guide plate 3 can seal the air outlet 12, so that a large-angle air sweeping in a vertical height direction can be realized, and more importantly, the connection position of the air guide plate 3 and a frame (housing 1) of the air outlet 12 is disposed at the lower side of the air outlet 12, so that an airflow backflow phenomenon between the air outlet 12 and the air inlet 11 can be prevented, and the performance stability of the air conditioner is ensured.
Because the air flow passes through the heat exchanger, the energy loss of the air flow is larger when the air flow passes through the heat exchanger, and the air flow is in an accelerated state in the whole process from an air inlet to an air inlet radian of the cross-flow fan, and the air flow is larger when the air flow is closer to the fan, so that the energy loss is larger when the air flow is larger when an evaporator is closer to the fan, the reasonable limitation of the air flow between the heat exchanger and the cross-flow fan is important for improving the performance of the air conditioner, on the basis of the above, the air conditioner indoor unit further comprises the heat exchanger 5, the cross-flow fan 4 and the heat exchanger 5 are positioned in the air duct shell, the heat exchanger 5 is provided with a first heat exchange part 51 positioned between the cross-flow fan 4 and the air inlet 11, in a plane perpendicular to the axial direction of the cross-flow fan 4, the distance between the middle point of the long edge of the first heat exchange part 51 and the axial center of the cross-flow fan 4 is L d or more than or less, and d is the outer diameter of the cross-flow fan 4, and the air conditioner is prevented from passing through the first heat exchange part 51, and the air flow resistance is reduced.
Preferably, the heat exchanger 5 further includes a second heat exchanging portion 52, the first heat exchanging portion 51 is fixedly connected to the second heat exchanging portion 52 and forms a V shape, and an opening of the V shape faces one side of the crossflow blower 4. A gap is formed between the second heat exchanging portion 52 and the mounting wall of the housing, so as to ensure that the intake airflow of the air inlet 11 can flow through the second heat exchanging portion 52, and further increase the heat dissipation area of the heat exchanger 5.
Preferably, the first heat exchanging portion 51 is inclined downward along a direction close to the front side wall of the casing 1, the indoor unit of the air conditioner further includes a water receiving tray 6, the water receiving tray 6 is located below a side of the first heat exchanging portion 51 far away from the second heat exchanging portion 52, and the first heat exchanging portion 51 inclined downward can facilitate condensed water generated thereon to be gathered in the water receiving tray 6 below the first heat exchanging portion 51 and then discharged to the outside.
In order to further increase the air intake area of the air intake opening 11, it is preferable to construct a pipe groove 13 on the inner side of the top wall of the casing 1, so that the pipe 7 (including the cable connected to the outdoor unit, the drain pipe, and the like) of the air conditioning indoor unit can bypass the top of the air conditioning indoor unit without being disposed at the bottom wall to occupy the area of the air intake opening 11.
The utility model also provides an air conditioner, machine in the foretell air conditioning.
